Hello everyone, I hope some of you can help me, I have a problem with a Huawei P9 Plus VIE-L09C02 (vodafone brand), in trying to install the no brand firmware (C432) the device does not start anymore, it gets stuck on the initial boot screen (huawei logo), and the only mode it enters is Fastboot Mode.
I describe all the steps I made:
-Reverted to android 6.0 using the rollback package and a stock rom I downloaded (using manual updater)
-Revert was successful , android 6.0 was running
-Wanted to try updating to android 7.0 once again using the normal updater.
-Normal updater said it was already at latest version, but it was android 6.0
-Tried updating to android 7.0 (same package as before) using dload method (manual updater)
-Updater stopped at 5% and said wrong package (weird, it worked before)
-Tried using the same rollback package as before to get it to region c900 (worldwide)
-Went to 100%, rebooted and stuck at boot-logo.
-After a while, rebooted my phone, but always stuck at boot-logo.
-No longer can shut down my phone. Holding power reboots.
-Tried getting to erecovery using vol+ & power. Reboots to boot-logo (vibrates twice during reboot)
-Tried getting to manual updater using vol+ & vol- & power. Reboots to boot-logo (vibrates twice during reboot)
-Can get into fastboot mode, but bootloader andr frp are locked. (Limited fastboot commands).
-Letting power drain shows red power circle indicating the battery is practically empty and will only boot to fastboot mode (plugged in)
-After charging still stuck at boot-logo.
Unfortunately I have the bootloader locked, (FRP instead unlocked), so I cannot install a fastboot system because it tells me that the commands are not allowed.
Trying to restore via HiSuite Proxy, and using all available roms, once downloaded and unzipped the installation starts, but from fastboot mode it restarts (I think it tries to enter eRevocery mode to install the system), and keeps crashing on the Huawei logo.
Has anyone already had the same problem and knows how to fix it?
I searched all the forums but couldn't find a solution to the problem.
