    • El LG 4 no funciona por fuerza g o cobayos; aquí está lo que tiene:

    • Pantalla 5.5" IPS "Quantum" con resolución de 2560 x 1440 (538 ppi)

    • Procesador de 6 núcleos 1.8 GHz, 64 bits Qualcomm Snapdragon 808

    • 3 GB RAM

    • Almacenamiento a bordo de 32 GB, expandible con 2 TB adicionales via tarjeta microSD

    • Cámara trasera de 16 MP, f/1.8 con OIS y foco automático guiado por láser y cámara frontal de 8 MP f/2.0

    • 802.11 a/b/g/n/ac wi-fi, Bluetooth 4.1 BLE y conectividad NFC.

    • Android 5.1 Lollipop

    • ¡No se necesitan herramientas aquí! El G4 incluye una muesca útil para remover el panel trasero fácilmente.

    • Si de reparabilidad se trata, eso se ve prometedor.

    • Nos hace sentir feliz (y, por suerte, no a nuestros iOpeners) de ver un proceso de apertura tan simple—especialmente comparado con las aperturas llenas de adhesivo en muchos teléfonos.

    • No necesitamos una visión de rayos X para ver que esta baterías puede ser reemplazada por el usuario.

    • ¡Pero los rayos X son mucho más divertidos!

  3. Desmontaje  LG G4: paso 3, imagen 1 de 3 Desmontaje  LG G4: paso 3, imagen 2 de 3 Desmontaje  LG G4: paso 3, imagen 3 de 3
    • La batería de ión de litio de 3.85 en el G4 está clasificada para un mínimo de 11.2 Wh.. Si bien el departamento de mercadeo de LG no afirma específicamente sobre la vida de batería, nos ha asegurado que la batería de 3000 mAhdura y dura.

    • El Galaxy S6 se clasifica muy cerca y detrás a 3.85 V, 9.82 Wh.

    • El iPhone 6 tiene una batería de 3.82 con una calificación de energía de 6.91 Wh.

    • A pesar de sus especificaciones impresionantes, pensamos que la características más excitantes de esta baterías es el hecho de que se puede remover fácilmente.

    • Recientemente, hemos visto una tendencia perturbadora en losteléfonos principales con baterías difíciles de remover. Hasta Samsung se ha rendido con su serie de teléfonos más nueva.

    • Es muy agradable ver que LG parece ser uno de los pocos en la guerra corporativa contra las baterías reemplazables por el usuario... ya que, tú sabes, las baterías se mueren eventualmente.

  4. Desmontaje  LG G4: paso 4, imagen 1 de 2 Desmontaje  LG G4: paso 4, imagen 2 de 2
    • Se ve como un pedazo de plástico común, pero esto, mis queridos amigos, es lo que llamamos libertad. Las pequeñas pestañas de plástico en la caja trasera permiten que se desenganche con facilidad—una simple tecnología que pensábamos haber perdido .

    • ¡Pero, esperen! ¡Hay más! Vemos algunos contactos que se asoman fuera del plástico.

    • Unos rayos X más tarde, descubrimos la antena NFC camuflada, no una bobina de carga inalámbrica.

    • Para aquellos que esperan usar tu cargador Qi justo al salir de la caja, este G4 no soporta carga inalámbrica sin una caja especial.

  5. Desmontaje  LG G4: paso 5, imagen 1 de 3 Desmontaje  LG G4: paso 5, imagen 2 de 3 Desmontaje  LG G4: paso 5, imagen 3 de 3
    • Ya llegamos hasta el marco medio sin necesitar nuestra caja de herramientas. Lo primero que sale de nuestra caja es nuestro Conjunto de Destornilladores Pro Tech con nuestro estándar Phillips #00.

    • Luego, tomamos una púa de apertura y la usamos en el marco medio para revelar el corazón del G4.

    • Tomamos nota rápidamente del número de modelo del G4r—LG-H811— antes de seguir adelante.

    • La fácil apertura y simplicidad de los componentes nos recuerdan a esos días de antaño de teléfonos Android de fácil reparación. El G4 parece ser una muestra de lujo estilizado y facilidad de reparación.

  6. Desmontaje  LG G4: paso 6, imagen 1 de 2 Desmontaje  LG G4: paso 6, imagen 2 de 2
    • La cámara selfie de 8 MP no está a la altura de nuestro spudger.

    • Lo más notable de esta cámara pequeña es el efecto alisado algo controversial que parece ser útil en situaciones fotográficas comunes—si no necesitas detalles nítidos.

    • Si bien no es visible, se supone que el G4 también tiene una filtro infrarrojo azul ultra delgado de 0.1 mm para bloquear la interferencia infrarroja, dándole a las fotos un look más natural.

    • LG está tratando de ayudar a sus fanáticos de Instagram: mejores fotos y todavía puede decir #sinfiltro. Técnicamente.

  7. Desmontaje  LG G4: paso 7, imagen 1 de 3 Desmontaje  LG G4: paso 7, imagen 2 de 3 Desmontaje  LG G4: paso 7, imagen 3 de 3
    • Sacamos la placa madre del G4 y vemos mejor todos sus componentes. Fíjate en estos circuitos integrados:

    • Samsung K3QF6F60AM-QGCF 3 GB LPDDR3 RAM

    • El Qualcomm Snapdragon 808 SOC de ocho núcleos, 1.8 GHz en capas debajo.

    • Toshiba THGBMFG8C4LBAIR 32 GB NAND Flash

    • Cliente WiFi 5G Broadcom BCM4339HKUBG

    • Circuito integrado de administración de potencia Qualcomm PMI8994

    • Circuito integrado de receptor de potencia inalámbrica Qi IDT P9025A

    • Transceptor LTE Qualcomm WTR3925

    Thanks for this great document. I was looking into how to fix the WIFI and Bluetooth. My older G4 has problem to turn on WIFI nd bluetooth, I finally get to see the parts oday by using your chart.......but I do not know what I can do......should I try to bake the mother board???

    • Chips traseros:

    • Amplificador de Potencia multimodo multibanda Avago ACPM-7717

    • Qualcomm WCD9330 Audio Codec

    • Transmisor Ultra HD SlimPort ANX7816

    • CI Administrador de Potencia Qualcomm PM8994

    • Controlador NFC NXP 47883

    Is the Qualcomm WCD9330 where the DAC resides?

    • Volviendo al resto del G4, sacamos la cámara frontal de 16 MP para mirarla más de cerca.

    • La cámara tiene un sensor de imagen 1/2.6", un foco automático de laser y un estabilizador de imagen óptica. El foco principal de discusión, sin embargo, ha sido la apertura de f/1.8 .

    • LG ha agregado algunas funciones avanzadas —como compensación de exposición, captura de imagen RAW y otras configuraciones—que pueden ajustarse manualmente.

    • Desde este extremo del G4 podemos vislumbrar su puerto infrarrojo (a la izquierda del orificio de micrófono).

    • Esperemos que el uso de este teléfono como un remoto no lo condene para siempre a los almohadones del sofá...

  10. Desmontaje  LG G4: paso 10, imagen 1 de 3 Desmontaje  LG G4: paso 10, imagen 2 de 3 Desmontaje  LG G4: paso 10, imagen 3 de 3
    • La complejidad de la cámara trasera y su estabilización de imagen es aun más aparente bajo los rayos x. ¡Qué marco! ¡Qué chips!

    • La pequeña cámara que sigue es la cámara frontal; un simple lente y sensor de imagen, si ningún mecanismo OIS.

    • Y de costado, la cámara trasera se ve como Nessie.¿Conspiración? Probablemente no.

  11. Desmontaje  LG G4: paso 11, imagen 1 de 2 Desmontaje  LG G4: paso 11, imagen 2 de 2
    • Dirigimos nuestra atención a la toma de auricular y la sacamos de la carcasa.

    • Nuestros ingenieros de desmontaje notan que la toma tiene contactos de muelle, lo que hace el reemplazo fácil.

    • Es un buen día cuando la toma de auricular es más fácil de reemplazar que la mayoría de los componentes en tus auriculares, o earpods.

    • La toma de audio está footlose y libre.

    • Los contactos de muelle son excelentes para conectar componentes; no hay soldado, no hay problema, y fáciles de reemplazar.

    • Las porciones más oscuras de los rayos X son el metal de los contactos que llevan potencias y datos hacia y desde la toma de audio a la placa madre. El resto del gris es simplemente el armazón de plástico.

  12. Desmontaje  LG G4: paso 12, imagen 1 de 3 Desmontaje  LG G4: paso 12, imagen 2 de 3 Desmontaje  LG G4: paso 12, imagen 3 de 3
    • Otro componente donde se aplica el contacto de muelle: ¡el vibrador!

    • El vibrador parece ser un motor de vibración de moneda. Las dos formas oblongas tipo O son las bobinas de alambre y la forma de yunque oscuro es un peso que gira, haciendo temblar al motor.

    • Desde un costado, los contactos de muelle obtienen más volumen y hasta puedes ver los filamentos de alambre individuales en las bobinas. ¡Genial!

  13. Desmontaje  LG G4: paso 13, imagen 1 de 3 Desmontaje  LG G4: paso 13, imagen 2 de 3 Desmontaje  LG G4: paso 13, imagen 3 de 3
    • Puntaje de reparabilidad del LG G4: 8 de 10(10 es lo más fácil de reparar).

    • El panel trasero y la batería se pueden remover sin herramientas.

    • Muchos componentes son modulares y pueden reemplazarse independientemente.

    • Los tornillos estándar Phillips # 00 hacen que el destornillador sea fácil de encontrar.

    • El ensamblaje de pantalla fusionado— cristal y LCD deberán ser reemplazados juntos si uno o el otro se rompen.

    • Y finalmente, nos gustaría agradecer a nuestros amigos en Creative Electron por su equipamiento y experiencia!

These X-Ray tear downs are really interesting. Hope to see more in the future!

Robert - Contestar

It must kill LG to have to use Samsung RAM chips.

Shawn Latin - Contestar

Corporations do not have emotions.

Almost everybody buys from anybody. Samsung sells parts to Apple, etc, etc.

It's all about maximising profit. Do that and nobody cares where the parts come from (unless your corporation can do it cheaper itself.)

Mike Reid -

Awesome! I loved this X-Ray feature.

Marcel Cintra - Contestar

Looks like the external speaker is also connected with spring contacts! I've had notoriously bad luck with external speakers, so this is awesome!

David S - Contestar

Anyone knows where I can purchase the rear camera module? My daughter shattered the glass.

Thanks in advance.

TheDoctor Who - Contestar

Any info on sensor chips?

hunter - Contestar

Hi. The plastic trim around the screen is all attached is it? There's no way of replacing it without replacing the whole screen?

Paul Garner - Contestar

you could probably use a heat gun to seperate the glass from the from i know you buy just the frame on amazon

aaron brogan -

Excellent guide, The place I work will not allow cameras on the work site, will the phone still work with the cameras removed completely?

taylorraymond - Contestar

Dude...Just cover the cameras up and call it a day (And disable the camera app)

niccotaglia -

There are a LOT of reports of the wireless charging breaking after several weeks to a month of use. As in, the Qi wireless charging ability completely dies. This is unfortunate!

On their website IDT is no recommending the 9025A and has a newer model, the 9025AC. Are these 2 facts related? Will LG upgrade newer ones to this chip?

WL1 - Contestar

Hi. My unit was manufactured in may 2015 (as per the serial number found on the retail box) and found out that units manufactured before sept. 2015 has a design flaw. Mine was purchased in june 2015. started to boot loop in oct 25 2015. Returned it to LG. their assessment was for mother board replacement.

chriztoph3r - Contestar

did u have ur motherboard replaced ? and is it working fine now with new motherboard?

Ashwani Bhat -

How can I change the bottom microphone? It stopped working/something might be clogged in it, and it doesn't appear to be in this teardown. Please help!

Emmet Spiegel - Contestar

Did you find any sulotion? I have the problem now. Thank you if you help me.

houman -

I'm also having this issue after about a year of use. Is it possible to access the port without having to take off the motherboard?

Myles O'Connor -

Hi all. My G4 H815 was manufactured in June 2015. Mine was purchased on 24 July 2015. started to boot loop on 19 November 2015. Returned it to LG the next morning and just got my motherboard replaced and received a November 2015 unit today. The technician does not know the problem of the unit when asked.

Walao Eh - Contestar

did you get the motherboard replaced ? and is it working fine with new motherboard now

Ashwani Bhat -

My husband dropped his brand new LG G4 in salt water. The motherboard burned. Can it be replaced?

Hendrik van Zyl - Contestar

My LG G4 is going through a "Bootloop" I wanted to know if the internal memory could be removed to retrieve the inner contents. That or just fixing the Bootloop seeing how LG admits to this being a defect in most device's in the components of the device.

Edgar - Contestar

how can i boost antenna main signal strength. phone showes no signal and iphone has 4 bars

Toby Andrus -

Same thing happen to my unit, bought in July 2015. Started boot loop and died off subsequently last week. Return to LG and had motherboard replaced.

Ralph K - Contestar

is your g4 working fine with the new motherboard or has it faced the bootloop issue again

Ashwani Bhat -

LG knows of the boot loop issue. It's seems to be a batch where the processor becomes loose from the motherboard. Heat gun and sticking freezer are quick very short term solutions. LG will replace phone or board no real questions asked.

Jon Hartsock -

Wait. H811? I have an unlocked G4 and it says H815

niccotaglia - Contestar

Any ideas on how to fix the bootloop issue?

aliceleemail - Contestar

It can't be fixed as it's not a software issue, it's a hardware issue. The only way to fix it is have LG replace it unfortunately :(

Craig -

Can be fixed short term by puttin freezer

Jon Hartsock -

Is it possible to remove the Toshiba THGBMFG8C4LBAIR 32 GB Flash memory and place it into another G4?

Jon - Contestar

Did you get a reply to this? I'd like to know, too.

matthewtreed -

Of course, I've done it yesterday

Александр Иванов -

Where is the Bluetooth module or antenna located?

Olaf Hoyer - Contestar

I have very bad 3G network connection the strength sucks. where is the antenna located?

Thanks for reply

psychokuh - Contestar

I lucked out buying the G4 last year for my wife. The screen, camera are superb. Now I'm glad the repairability is strong. Now this is a primary deciding factor in buying a phone. I don't think I'll be buying a new phone for a while, even this G4 was second hand, like new.

Jack - Contestar

The NFC antenna can it be upgraded or possibly can I make one

Ace - Contestar

my phone just stopped working the other day for no apparent reason. new chargers , different places and a new battery today. no luck . I noticed in the teard

Hello

I burned motherboard model LG G-4 (H 818P), and I want to buy please give me Information manager.

Sol69h Sol - Contestar

Hello, you have the PMI8994 and PM8994 Power Management ICs on your motherboard?

Roman Galifor -

I give a message to Iran and to How can I access lg g4 phone motherboard model h818p I get?

Sol69h Sol - Contestar

hi needs help from where can I buy Samsung K3QF6F60AM-QGCF 3 GB LPDDR3 RAM

Omar - Contestar

Why do you think about RAM. RAM crashes in the phones very rarely, DO NOT THINK THAT BOOTLOOP WAS CAUSED BY RAM OR CPU. THIS IS VERY BAD NAND SOLDERING. REBALL IT AND ALL WILL BE NICE.

Александр Иванов -

can somebody learned in the ways of motherboards tell me if there's any possible way to pull off pictures, music, notes, etc. after the G4 goes into its bootloop? I have a lot of priceless files and data on this phone I would probably sell my soul for. As far as I know, it's irretrievable. Can someone confirm or deny this?

To anyone considering this phone, stop. This is my second LG G4 that died due to motherboard manufacturing issues. They aren't isolated instances. Most users have had this issue within 6 mos. to 1 yr. of purchasing. Interesting how the phone dies right around the end of its 1-Year Warranty.

I have no interest in having this phone replaced by LG or repaired since I already ordered a new phone. I just want to extract the files. There has to be some way to do this. I find it hard to believe that in December 2016 that this can't be done. The only reason I haven't gone Office Space on this otherwise useless phone is because I still have hope I can retrieve my lost files.

LGMakesMeSad - Contestar

Of course, but only if you have equipment. Only some of repairman can do it.

Александр Иванов -

Put it in the freezer in a Ziploc bag. Wait about an hour. Should boot normal. But will give u a short window to get files off. Once chip starts heat up, jumps into boot loop again. I had good luck sandwiching phone between 2 big ice packs and using my laptop with usb. micro cable download all files needed.

Jon Hartsock -

Desolder the eMMC chip and insert it into the correct eMMC chip reader. Unless the data is encrypted, you can access even the things you wouldn’t access through your phone’s file manager. Then you can even change the bootloader, root the phone, download everything eg. documents, load or store backup, perform recovery of your deleted files.. When you’re done, reball the chip back on the motherboard and your phone may work fine if you do everything correctly.

patrikstaron -

Does anybody know where the GPS Antenna/contacts are? My GPS stopped having reception a while ago, would like to see if there is a fix possible.

hans - Contestar

I'm aware the g4 has two external LDI stickers. One in the battery compartment and one on the battery itself. But does it have internal ldi stickers?

Nunyally Li - Contestar

where can i buy a new motherboard ? cause they ask ridiculous prices to repair outside warranty . and repairing? i can do that myself not that difficult

maurice1975 - Contestar

Anyone know which IC deals with the touchscreen? I have a new frontpanel and digitizer and LCD, all were working before the Bootloop/dead phone issue. I got the phone working again with a heat gun to only the mother board. but no touch screen. Roger - 1/28/17

Roger - Contestar

Is there a way to replace whatever part of the phone manages display? I got my LG wet on the weekend. Phone working - but no display. I can live with the sketchy speakers. Been in rice 2 days. Can only answer in my car on bluetooth. it will not "swipe" to answer, etc. on a blacked out screen.

Chattering H - Contestar

On the mainboard:

What function does the mainboard smaller part (under NFC chip) have?

I have the mainboard with that smaller thin lateral side (antenna I think) broken but it works apparently normal: bluetooth, wi-fi signal, carrier signal, etc

Ramre - Contestar

No Light Display. .. Took my G4 apart to repair micro usb hub and when I put it back together I can no longer see the screen without nothing short of a bright light shining on screen. anyone have a few suggestions of possibilities of what I done wrong? does screen get sealed with something or did misplace the lcd lights maybe?

Have an LG G3 will not charge battery, Help Greatly Appreciated

maryannhopper - Contestar

I love this… It was so informative… Keep up the great work!

Jesus Child - Contestar

The seal in front of the camera (removed in step 5) I took off thinking it was just for decoration, but little did I know it also kept debris from entering the camera mechanism! Now, my camera sometimes refuses to boot, but if you take a needle and go around it’s perimeter and clear away dust, it starts to work. In addition, and the reason I came here, is that I now have a more permanent spec of dust behind the lens itself, so I will have to disassemble the camera or get a new one…

Meow meow - Contestar

what is the gold-colored paper strip called and can I get it separately?
