[Huawei P9 Questions & Answers] Ogameplayer:
Hey xda community,

last night i run into a tricky situation.

First, I explain what I did

I bought me the P9 EVA-L09 via Telekom Germany.

cause i don't want the Telekom **** on my device i decide to TWRP, Root, and flash P9 stock Rom on it.

Unlocking and install TWRP with the SRK Tool works fine. Install the Root was a bit more tricky, because windows lost the correct ADB connection when i go into TWRP Sideload Mode. Because that does not work, i decide to flash the P9 Stock ROM without Root to come forward.

While flashing, (i don''t now anymore which method i choose to flash) an error appers, and the flash process canceled.

The Device don't boot anymore. After a loot of googeling and testing, i've found out that the problem was the encryption of the /Data Partition.

TWRP was unable to mount it, same for the /cust and one more.

After reading about other Methods to get the Phone work again i try this Method i've found on xda.

Unfortunately the "press all buttons on the phone" Method don't work.

I also tried out the Huawei Update Extractor to flash single image files to the partitons of the phone. I used the dload file form the previous Method

But that don't work. fastboot already replies with "Remote Command not allowed"

i changed the Method a bit. I've put the BOOT.IMG and RECOVERY.IMG an an SD card and flash it via the Install IMG Funktion of TWRP.

That workes very well and expect the /data partition every partition was mountable again.

Then i used the "Fastboot flash system SYSTEM.IMG" again, and tada it works without errors.

The device is booting again to Android, but it reports that the /Data Partition Decryption failed and i have to enter the Recovery Mode and do a factory reset to unlock the partition. If i reboot for get rid of this error the phone does not boot into the Recovery, it boot to the eRecovery which is useless for that because it only provide the eRecovery function instead of also a normal factory reset (how dump is this :eek: )

Now the state is, phone boots normal, reports the /Data is not decryptable, reboot to eRecovery, shutdown or reboot. It does really nothing else.

I can't get into the Fastboot/Download Mode, it ignores the Key Combination Volume down + Power. If i press this it starts normal.

I also can't get into the recovery / TWRP Mode, it ignores the Key Combination Volume Up + Power. If i press this is starts normal.

I've also noticed that the Phone is not conecting to the ADB on my computer, only the virtual CDROM from wich the HiSuite is installable connects.

I've also noticed that the eRecovery is not able to starts WIFI on the phone. It errors with "Starting WIFI failed!"

I also tryed out another time the dload function. This changed nothing. Phone boots still normal and run into the Decryption problem.

And i tried out to boot into fastboot or recovery after a cold reset, battery empty

Now it's on you. Has anybody an idea how i can solve one of the above problems. I think when one is solved the others will disappear via flashing new TWRP or so
