[Huawei P9 Lite Questions & Answers] Nicramcio:
Hi!

As in the title, something wrong with my P9 Lite happened. Namely, the day before yesterday he decided to turn off by himself with a 50% battery there, but turned on normally after 2minutes. At night from Wednesday to Thursday it discharged and in the morning after charging I couldn`t start it.

The phone either booted and stopped several times on the Huawei logo and the note "Powered by Android". I can enter by using a key combination the eRecovery mode. Ultimately, it started up one time, and it worked until the evening and until it was discharged again. After that it has been charged to 60%, one time he turned on but after an hour of further charging he fell on the amen. I've been trying to fight him since the morning that maybe he'll turn on like yesterday, but no. I had this situation for the first time in August 2018, then in February and July 2019 with that it was probably a decent brick then, because this black screen was constantly displayed with an exclamation mark and some error. A visit in smartphone service has always helped, but I can't spend 80 PLN again to fix that issue. After the repair in July, I specially wrote the system version so that I would have knowledge for the future in the event of a repeat. The phone had the firmware as below:

Today I downloaded the system from this link: huawei-firmware.com/rom/huawei-p9-lite/vns-l21/9618

However, at 5% installation the error crashes and I can only restart the phone. I tried using two different sd cards, so the option of the card being faulty is 99% out of the question. I hope that some good soul will help me, because I believe that I can solve this problem independently at home and not necessarily after paying with a GSM spec. : P

I forgot to add that the phone has not been updated since it was repaired or anything. I didn't do any treatments myself with loading custom systems. He just turned himself off, without any previous signs of malfunction and end. I was surprised that the phone doesn`t want to accept the software that was uploaded by a service technician ... but maybe I am doing something wrong.

At the end fastboot situation:

PHONE: unlocked

FRP: locked

EDIT:

In another forum I got instructions to upload rollback and then soft "C432B160" and everything will be good. I took it up and the rollback installation was completed, after a minute the phone rebooted. Unfortunately, this problem caused another problem, because since I installed rollback I can`t enter the erecovery mode, where I have possibility to shut down...so phone stuck with the Huawei logo all the time. I was supposed to upload this software, but I had to leave the house and the phone was completely discharged when I returned. From that moment only fastboot mode starts, or after switching on and trying with different phone buttons, it always becomes a logo and got freezed. I was charging it for an hour, but after disconnecting from the charger the LED was blinking red and I saw on the screen message about 0% battery. After that another situation...I connected it to the charger and after a second showed me message of 100% battery, but after a second phone started automatically and hung on the logo again. After unplugging it from charger and trying to start without charging, the LED flashes red and message about disscharge was on the screen. Now I`m seriously starting to wonder, if anything from this phone will still be..... :/

Links to rollback and software (according to which I did not manage to upload before discharging the phone):
