Huawei P10 Lite bricked | Func NO: 15 (bl31 image)

[KleinDev]

Hey my friends,

my huawei got soo many times soft or hard bricked.
And any time Dc softwares helped me to unbrick my phone.
(It's my old phone)

Now I have a tricky problem:

First, my Phone was totally black and stucks in fastboot mode.
DC-Phoenix made it to boot out of fastboot and go in Error mode.
So I was trying to ref-flash my recovery and system.
But, oh, the bootloader is locked?
Okay, luckily I have the unlock code from HCU, so..

I unlocked the bootloader and my phone wants to reset.
But wait! Sh*t! There is no system to do a factory reset!

So, my phone stucks in booting to error mode, turn off, boots in error mode.
I charged my phone the full night long with an huawei fast charger, but the battery is still on ~0-1%
No chance to enter in fastboot, recovery, erecovery or dload mode


So, is there anyone who could help me?

Greeting

OMG!

I connected two points from the board, Port 2 and 3, the bigger gold marks. (See image with the red dots under)
Cconnected my phone through USB with the PC pressed VOL DOWN and wait for next reboot.
Now the phone is in SERIAL MODE

Steps to reproduce:

1. Reboot ur PC (in my case windows 10) with pressed Shift key and click on "restart".
2. You must select the advanced start up optiions to disable the driver signature.
3. After restarting, download this file: https://sigmakey.com/nfs/content/610...1.0_driver.zip
4. Now it's time to get ur phone to serial mode.
5. See above, connect the port 2 and 3, reboot ur phone.
6. Now go to the Device-Manager on Windows, u see a "USB SER" device.
7. Right click on it and select update drivers, choose the 2th Option and select the path to the extracted HUAWEI_USB_COM_1.0_driver.zip
8. Now ur dirvers are installed
9. Open update OEMINFO
10. Check "Use BOOTLOADER"
11. Select ur bootloader (in my case, I think, Kirin 658)
12. Go to Testpoint files
13. In my case it was WARSAW_WAS_P10_lite
14. Click on update

Voila! Ur bootloader was reflashed and ur phone boots in fastboot mode.
Good luck everyone!


But, rebooting ur phone will take it back to the error mode..
So replay the steps
