Desde hace un tiempo me ah venido dando problemas mi teléfono con diferentes problemas.

No reconoce la sim

Problemas de batería

Micrófono dañado y parlante dañado..

Busque solución en algunos técnicos de mi zona y nada.. Según no tiene reparación..

Tendrá arreglo!?

El cual funcionaba perfecto aún teniendo la pantalla rajada.

Al cambiar la pantalla se queda con la hora y no deja hacer nada no sale de hay.

Entro en recoveri y me deja moverme por el menú de el.

Si salgo de em reiniciándolo apagándolo etc.

Sale de nuevo la hora como si detectara que tiene puesta una funda.

I would be happy if someone who has the software zxw can find me the resistance level and the size of these resistors.

(By the way, so that more people can use this in the future, I will mention that two of them are on the sim way)

I marked the resistors here.

Thanks!

I had a broken P30 pro screen, with it, the earpiece speaker (no grill, vibrating one). replaced the piece and cant hear, is there something special I should know about like what apple does with linking the home button/batteries to motherboard? Everything seems to be in order

Another point - I actually managed to charge it ONCE from 10% to 60% without it stopping, battery temp was normal (13-18°C, showing at diagnostic tool, --talking about old battery, which is the one im able to boot with and is still in phone, coz new one doesnt work for me - any ideas why?) Only thing i thought might cause the problem where broken pins on old flex cable i already replaced (pins on mobo seems fine with naked eye, dont have microscope sadly)

So another question, where is temperature sensor actually located, so is there a way to check it if it is ok physically?

Also in eRecovery mode top right icon (battery% one) shows charging when charger plugged in.

I tried :

• Factory reset (settings)
• Factory reset (Power+VolUp)
• Clear cache (Power+VolUp)
• Hotswap battery while charger in (heard it might boot with the new one coz it thinks its old one)
• Cleaning pins
• 5 different chargers from 5W to original one

I BEG FOR HELP, IM SO HOPELESS haha

THANKS FOR ANY TIPS.

Does the entire back need to come off or can the glass be replaced from the outside?

Hi dear iFixit community,

I have a problem with my P30 Pro. My WiFi and Bluetooth are both dead. When I turn the toggle on it stays on for 1-2 seconds and turns it self off. It doesn’t scan for any networks though as it stays blank. So could anyone please tell me the location of the wifi chip on the logicboard? The teardown left me clueless..

It had a drop damage and got an entire new Housing/Oled Display assembly (Original Huawei part). Celular data etc. still work though.

Thanks in advance.

I am sure the problem is in the 2-jack section, because before it stopped working it sometimes got really quiet so I could barely hear anything, and I could fix that by rotating the sound jack so it can get better connection.

soo idk if the images are here somewhere, I'll just send a link now https://imgur.com/a/qmcJq7M

idk what should I connect to what because of the wire numbers being off @amber

@abhimannuec should I connect it like this?

my display broke so i decided to change it the first time by myself including a new battery. after assembling the phone back together, i tried to switch it on. the huawei and android logo are being shown on the display, but 10 seconds after that, the screen gets black. i tried entering the emui bootloader and got in. i did a whipe and factory reset, cleared the cache but nothing changed. i tried everything else too, but it looks like it cant boot android. what should i do now?

⟐ Answered marzo 11, 2023 at 18:25 GMT-7

I replaced the screen and the device seemed to functioned perfectly only to find the power button would not respond and/or turn on or off the device.

I know for a fact it was working before. Still with no solution a second P30 Pro came into our shop a week later for a screen replacement again. I just completed the screen repair only to find it has the identical issue with the power button!!!

anyone have any solutions or come across this before!? I’m out of ideas.

Additionally the main camera does not work, and apps say Error with camera etc each app warns uniquely that it cannot connect.

Sometimes after a reboot, like 30% of the time, camera can activate, however main camera cannot focus. Wide and tele seem fine.

So what seems to be the issue based on above?
