Se cayó tu S8? Lo tienes en el mismo bolsillo que las llaves?

Lo más probable es que la parte de atrás del vidrio ya esté destrozada. Use esta guía para reemplazar el cristal trasero del Samsung Galaxy S8.

Si el repuesto no viene con el adhesivo pre instalado, deberá comprar adhesivo para el cristal trasero y el lector de huellas dactilares. Puede comprar adhesivo precortado o cinta delgada de alta adherencia.

    • Abrir el dispositivo pondrá en riesgo tu sellado impermeable. Ten preparado adhesivo de repuesto antes de proceder o trata de evitar exposición a líquidos si vuelves a montar el dispositivo sin sustituir el adhesivo.

    • Calienta un iOpener y aplicalo a lo largo del borde curvado del S8 durante 2 minutos aproximadamente.

    • Necesitarás volver a calentar y aplicar el iOpener varias veces para alcanzar la temperatura suficiente. Consulta las instrucciones del iOpener para evitar sobrecalentamiento del dispositivo.

    • También se puede utilizar un secador de pelo, pistola de calor, o lámina caliente, pero ten cuidado de no sobre calentar el móvil -la pantalla OLED y la batería interna son susceptibles a daño por calor.

    • Mientras esperas que el adhesivo se ablande, lee el resto de instrucciones para saber dónde ejercer palanca.

    What type of adhesive should be used to seal? Or better said, what would you recommend.

    Ion Ion - Contestar

    I’d recommend precut adhesive designed for the rear cover. If that’s not available, thin, hi-bond double sided tape like 1 mm wide Tesa 61395 tape will work well.

    Adam O'Camb -

    Yes, different microwaves have different power levels (e.g., wattage) so one microwave may explode the iOpener after 31 seconds of heating whereas another microwave will barely warm it. It would be helpful to have a more precise target temperature. My microwave is fairly weak so I’m heating it for seven seconds for every two minutes against the phone. In theory, this should slowly add more heat than is dissipated into the phone and surrounding atmosphere.

    • En los siguientes pasos irás cortando el adhesivo alrededor del borde del cristal del panel trasero.

    • El adhesivo del panel trasero está situado de la manera en la que aparece en la primera imagen.

    • El patrón de adhesivo a tener en cuenta para hacer palanca, visto desde fuera es el siguiente:

    • Porción ancha de adhesivo

    • Porción fina de adhesivo

    • Evita hacer palanca aquí, para proteger el sensor de huellas

    Go clockwise (or counter-clockwise) around the border to avoid causing extra stress on the back. The bottom has a lot more adhesive than you think, towards the top-center.

    Michael M - Contestar

    Failing completely at this step. I’ve heated the opener like 5 times and the phone is hot to the touch, but I can’t get even the tip of the pick into the opening.

    Added a hair dryer to the effort and stil making no headway at all.

    • Una vez que el panel esté lo suficientemente caliente al tacto, coloca una ventosa lo más cerca posible del borde calentado, evitando la parte curvada.

    • La ventosa no aplica una buena sujeción en la parte curvada del cristal.

    • Si la tapa trasera del teléfono está rasgada, la ventosa no podrá adherirse. Intenta levantarla con una cinta resistente o pega con adhesivo instantáneo la ventosa y permite que se pega así puedes proceder.

    • Levanta de la ventosa e inserta un spudger Haldberd o púa de apertura debajo del cristal trasero.

    • Debido a la curva del cristal, deberás tirar hacia arriba con la ventosa e introducir la herramienta plástica de forma paralela al plano del teléfono.

    We can't seem to get anything between the edges even after heating the back panel. Any tips?

    Megan Kennington - Contestar

    Hi Megan, unfortunately the adhesive is super tough on this one. I’d recommend carefully continuing to apply heat, very gradually so that you don’t accidentally overheat the battery. Eventually you should be able to get a little gap with the suction handle.

    Adam O'Camb -

    I’ve been attempting to get the adhesive to loosen for four hours now. Exactly how much time is this supposed to take? The pictures makes it look like it should be easy. The adhesive still hasn’t budged and I’m beyond frustrated.

    Lori Lucas - Contestar

    Hi Lori, sorry to hear the adhesive is being extra stubborn! If reheating and reapplying the iOpener isn’t working, you can try heating the edge with a hairdryer or heat gun. That way you can get more heat onto the edge faster, but be very careful not to overheat the battery inside.

    Adam O'Camb -

    I used a stanley knife - very carefully, after trying for several hours to get the adhesive to loosen. I bought another back cover with adhesive for the assmbley, which is the best option in my opinion. Just be careful not the scratch the case of the phone, and be prepared for the back glass cover to break when removing it.

    James wright - Contestar

    The manufacturers really want to make this impossible, huh… I’ve gone 3 years without ever cracking this phone and end up cracking the corner of the back trying to prise it open. Probably should’ve gotten a heat gun too. This is super tight.

    Benjamin Chaim - Contestar

    I am currently working on this. I have heated the phone to just barely to hot to hold. No matter how many times I've done this and pulled up with a suction cup I cannot get an edge to lift.

    Being that this is my second phone repair does anyone have advice on this? I've watched several YouTube videos and it looks so easy.

    DAVID LAWRENCE - Contestar

    I suggest you try to lift on the middle of an edge using the thinnest spudger you have. also as the edge is curved remember to insert it so to follow the curve. Hopes it helps

    Cajuteq -

    Our issue was that a small gap would open when using the iOpener, but not large enough to get spudger or opening picks in there (also tried hair dryer but same result). Luckily as a guitar player I had some very thin nylon picks that we were able to get in there, which opened up a large enough gap to get the spudger and opening picks in. From there, we were able to heat the other sides and guide the spudger around the entire edge to get the back glass off.

    First we used a Dunlop nylon .38 mm guitar pick, then a .60 mm pick, and that allowed us to get the spudger in.

    Dan Coleman - Contestar

    This is by far the hardest part of any tutorial that requires you to open the Samsung. The iOpener is totally useless on my opinion (it doesn’t get warm enough). What I did instead is use a hairdryer but it took me time before I could get the adhesive soft enough. Especially since I was not able to measure the temperature of the phone will warming it. Also I think that the halberd is not thin enough so I used a radiology sheet (don’t know the right word in English) to get into the phone and it was much more effective and time saving. Thank you for the tutorial and good luck !

    Thomas Alliot - Contestar

    Use a utility knife blade to work around the edges. Careful not to pry on the blade since you risk cracking the back

    Derek Gibson - Contestar

    I bought a back glass replacement kit with the battery kit since mine was cracked already. I used both iOpeners to uniformly heat the whole back along both long edges. I microwaved each pack twice over 10 mins. 5 mins apply, microwave, 5 minutes apply. That worked!

    William Mellema - Contestar

    Similar to other posts, this appeared simpler. I have a couple of tube socks filled with rice that we use a lot for a sore back. Put in microwave for 5 minutes and an amazing heat pack. So I thought I would try this instead of the iOpener as it just was not getting the phone warm enough. Wrapped the phone in the riced-filled-tube sock for a couple of minutes, to the point where I could at least pick it up and hold it. Also, I have the full IFIXIT kit, so I pulled out the jimmy. Viola. Got right in and then allowed me to use the halberd and picks to finish it off.

    kendrickcc - Contestar

    I was able to do this with the iOpener warming pad by microwaving for the suggested 30secs then leaving it on for 10 mins. repeated this process 2 more times for a total of 3 times @ 30 mins and used the suction tool and the picks to get it open. There is a considerable amount of adhesive on the tops and bottoms of the phone. So consider warming the whole phone before doing it.

    Note: if you already have a cracked back panel (like me) prior to starting the process, consider getting the replacement as the already cracked panel will crack even more as you are cutting away at the adhesive. Goodluck!

    Harry Williams - Contestar

    After over an hour of trying to use heat and the suction tool loosen the adhesive and try to get an opening on one of the edges, I used the blue spudger to see if it would slip thru the edge and it did. I was able to loosen the majority of the back glass but ended up getting excited and rushing and cracked the top corner. I was able to complete the battery replacement and use the cracked back glass. I’m going to order a replacement for that and that should be easier. Lesson to be learned, if any part of the back glass is getting a little tougher to loosen, hit it with heat again just to be safe. The rest of the replacement we pretty straight forward.

    MJH - Contestar

    The spudger provided in ifixit repair tool kit is not the same as the one used in this guide and can not be used in the same way as the spudger used in this guide. So I am pretty much winging it on the most critical point of this disassembly. This is extremely frustrating.

    Brent Neilson - Contestar

    I’ve repaired many iphones but this was my first attempt on a Samsung. I made no headway at all on opening the case and I’ve decided to just live with the battery being kind of weak. Even with a short life, I would much rather use this phone than an Iphone.

    r torrance andrews - Contestar

    I've tried 5 times in over the course of 4 hours to loosen the adhesive on this phone, and it won't budge. Unfortunately this kit is useless to me

    • Desliza la púa de apertura hacia abajo por el costado del teléfono, separando el adhesivo.

    • Hazlo con cuidado, debes evitar salirte de la hendidura. Si se te dificulta, vuelve a calentar y aplicar el iOpener.

    Cracked my glass multiple times, do this very slowly and with more heat to each new area.

    • Repite el paso previo de calentado y corte del adhesivo en los tres bordes restantes.

    • Deja una púa plástica en cada borde del dispositivo mientras continúas para evitar que se vuelva a unir con el adhesivo.

    • El cable del sensor de huella conecta al teléfono con el cristal trasero, cerca de la cámara principal. El cable es muy corto y se debería desconectar mientras se retira el cristal trasero.

    • Mientras levantas el cristal trasero, asegúrate de que el cable naranja con el conector azul se ha desconectado.

    • Utiliza las púas para eliminar cualquier resto de adhesivo que haya quedado y abre con cuidado el teléfono.

    • Si el cable del sensor de huella está conectado o trabado, no continúes abriendo el teléfono. Desconecta el conector antes de continuar.

    • Durante el montaje, para reconectar el cable del sensor de huella alinea el cristal trasero hasta que el cable del sensor esté sobre el conector de la placa. Entonces, usa la parte plana del spudger para presionarlo cuidadosamente hacia abajo y conectarlo.

    • Quita el cristal del teléfono.

    For reassembly, if the fingerprint scanner is removed from the back cover: it’s much easier to place the fingerprint scanner in the small compartment on the back of the phone, connect it and then finally put the replacement back cover on. The adhesive on the inside of the back cover will get connect to the fingerprint scanner and hold it tightly.

    Brian Hoffmann - Contestar

    I wish I saw this comment earlier because it's absolutely correct. I hope iFixit remedies this because it is incredibly difficult to connect the sensor when it's already adhered to the glass. It took me a good while and I ended up using some tape to keep the back glass aligned while I used the spudger to push blindly until it snapped into place. The only way I knew it worked was because I tested the sensor before fully sealing the glass.

    Preston Steimel -

    The NFC antenna and coil assembly might get stick to the back cover due to adhesive spreads while trying to pry the back cover to open the phone. Take a look inside to ensure the assebly has not got sticked. If so, try using a credit card like plastic to get it peeled of from back cover without breaking the assembly always paying attention to the fingerprint sensor as well.

    dcode - Contestar

    Reconnecting this cable seems like it would be very tricky: how can you get the pieces close enough together to make the connection without having the perimeter adhesive start to connect the front and back? It seems like that adhesive could easily get messed up at this point.

    r torrance andrews - Contestar

    To remove the akku, high temperature was NOT constructive!! I used ethanol (cc.) instead and it worked in between 2 minutes. I think it´s also better to open the coverage in this way. Instead of heating it.

    • Para reinstalar la tapa trasera:

    • Usa unas pinzas para pelar algún residuo de adhesivo en el chasis del teléfono. Después limpia las areas de adhesion con alcohol isopropilico de alta concentración (al menos 90%) con una tela libre de pelusa para preparar la superficie para el nuevo adhesivo.

    • Pela el protector del adhesivo en el nuevo cristal trasero, alinea cuidadosamente el borde del cristal en contra del chasis del teléfono, y presiona firmemente el cristal en el teléfono.

    • Sigue esta guía para reinstalar el panel anterior o un panel sin adhesivo preinstalado.

    • Si lo deseas, puedes reinstalar la cubierta sin sustituir el adhesivo. Retira cualquier gran acumulación de adhesivo que pueda impedir que la cubierta esté nivelada. Después de la instalación, calienta la tapa y aplica presión para asegurarla. No resistirá el agua, pero el adhesivo normalmente es lo suficientemente fuerte como para aguantar

    • Puede que también necesites transferir el marco de la cámara hacia tu nueva parte. Si ese es el caso sigue nuestra guia en como remplazar al marco de la camara

    Bonjour,

    Vous parlez d’ajouter de l’adhésif, comment et où le trouve-t-on cet adhésif ?

    Difficile à appliquer ?

    Cordialement,

    Stéphane

    Steph D - Contestar

    Mille excuses, je viens de voir les “adhesive strips” :)

    Steph D - Contestar

    I broke the rear glass trying to get all the adhesive off! Be very careful!!

    jimhunz - Contestar

    Be careful with the NFC Antenna/Charging Coil Assembly. It’s covered in a black wrapping that can look like adhesive. Don’t scratch too hard with the spudger, the wrapping will come off!

    Michael M - Contestar

    Hello, I appreciate that tuto, very detailed for a somewhat subtle job . Is it possible to use one of the 7000 or 8000 glues in place of the adhesive Stickers ? Thanks

    • Si estás instalando un nuevo panel de vidrio trasero, también deberás transferir el sensor de huella digital a tu nuevo panel de vidrio trasero de la siguiente manera:

    • Vuelve a calentar el iOpener y aplícalo al sensor de huella digital montado en el vidrio trasero.

    • Presiona el sensor de huella digital fuera de su adhesivo desde en la parte externa del teléfono.

    • Si el sensor no sale, cuidadosamente deslizar un spudger Halberd debajo del respaldo de plástico para ablandar el adhesivo antes de empujar.

    • Esto hará que el adhesivo posiblemente no se pueda volver a utilizar, así que intenta empujar con tu dedo primero.

  10. Reemplazo del Cristal trasero del Samsung Galaxy S8: paso 10, imagen 1 de 1
    • Si el adhesivo del sensor de huella digital está intacto, se puede reutilizar. De lo contrario, reemplázalo con algún adhesivo precortado.

    • Luego de remover el viejo adhesivo, limpia los bordes del sensor de huella digital con alcohol isopropílico de concentración alta (al menos 90%), luego aplica el nuevo adhesivo.

Conclusión

Luego de aplicar nuevamente adhesivo, seguir estas instrucciones en orden inverso para armar nuevamente el dispositivo.

Will the phone still be water proof after this

gavinjay - Contestar

No. After the adhesive is removed, your water resistance is as gone as your warranty.

James watling -

after the rear panel is removed? ... no...

John Joiner - Contestar

Nice its simple action with this tutrial

Seibors - Contestar

Great tutorial, simple and straight to the point. My type of learning.

If I could add just one little thing….

I myself would have loved if you would have touched on replacing the fingerprint scanner ribbon when replacing the back glass. , I learned

None the less, you gave me knowledge and I thank you…

Alvin Thomas - Contestar

it will be if you do the process 100% correctly and ensure a proper seal by applying enough adhesive at the edges (yet not too much!) at the edges and around the camera and fingerprint scanner. In theory that should do it, but bear in mind i have not tested this

Robin Bogaards - Contestar

Where to buy original rear back glass?

a.voloshin - Contestar

Under “parts required”, I see:

Galaxy S8 Rear Glass Panel - $90

Galaxy S8 Aftermarket Blank Rear Glass Panel $15

1. I assume I only need one of these parts, correct?

2. if correct, what’s the difference between the two? they look like the same exact part, except the $90 is Samsung branded and the non-branded is $15

Thanks everyone!

Jimmy Ng - Contestar

That is correct. The non-branded one is generic. The one that says “SAMSUNG” is name brand and just costs more. You can use either one.

Albert Ayala -

What adhesive do you use ? can you recommend ? I bought one that already had adhesive on the back panel but one side raised up slightly, I could get my finger nail underneath and the gap was noticible.

Links to product would be great.

Thanks

Dave

dave - Contestar

Hey Dave a the top of the guide we list the rear cover adhesive you can find in our store!

Sam Goldheart -

Thanks for the guide, was handy. Definitely needs glue to hold the new cover, fingerprint sensor and the other bit on - just ordered a B-7000.

drpotatoman - Contestar

very hard and difficult to pass the spudger under the glass !!! But I didn’t abandonned I did it! thanks for the share.

SAINTE-COLOMBE Vonjy - Contestar

I have learned my lesson! Edge dropped phone. Display cracked , force created a hidden micro crack in the back glass. I heated the back very well, but still that thing cracked as I was finishing. Take my advice, and anytime you work on this phone buy a new back, then just break off the current one. You will be sooo much happier. Don’t forget to make sure it comes with adhesive.

Max Reynal - Contestar

The replacement back glass could use some more adhesive towards the top and bottom. It doesn’t sit as well as it should. Definitely no longer waterproof

Michael M - Contestar

This does not show how to reinstall the adhesives.
