EDIT:
It seems since there is no Huawei P8-Subforum, my thread seems to has been postet to misc. Development. Im sorry about that!
Hello there,
I spend the last three hours trying to get the device (L09) to work again. I made the terrible mistake to update my phone with custom recovery (TWRP) installed. My target is to upgrade from B191 to Marshmallow.
The main probleme here is that I don't own a micro-SD card plus the internal storage contains a dload-folder which I can't delete.
My current situation:
- The phone is bootlooping at bootanimation
- I can access the fastboot-mode, stock-recovery and upadte-mode
- My internal storage (intenal SD-Card) contains a folder named "dload" with the B200 firmware
- I flashed the stock B200 recovery.img and boot.img (extracted with Huawei Extractor)
- When going to update mode the phone proceeds to 5% and then shows "Software install failed!"
I don't really know how to proceed from here on. I tried to flash TWRP again to clear the dload-folder and place another firmware, but somehow twrp can't be installed anymore - flashing shows "OKAY" but when booting into recovery, the same old Huawei recovery is booting. Also I'm confused as to when to leave the USB plugged in or disconnect it.
My current plan is to revert to 170 firmware to start completely over. I downloaded the 170, 200 and 313 firmware.
How to proceed?
EDIT:
I flashed recovery.img, boot.img and system.img from B170 and now the boot repeats at the Huawei logo. After flashing boot.img and recovery from B200 I get to the bootlogo again, which is stuck.
Solution:
After flashing boot.img from B191 the B170 firmware booted successfully. I got a few random reboots at the start, but they quickly grew less and now I have a somewhat stable B170.
Upgrading to B191 or B200 didn't work, tho. I'm trying to get behind that now.

Hi guys!
I have an issue here with the Huawei P8. I wanted to go back to stock from ARROW ROM, so
-I used Huawei Extractor to get the stock recovery and flashed it via fastboot adb
-Updated my phone with the 3 button method and put the DLOAD folder into my SD card
-I used B394 to get the recovery img and to update as well (it was ~1,6Gb)
The update started and everything worked fine, the phone said everything is fine but my phone stuck in bootloop. I mean it doesn't restart or anything but all I can see is the Huawei logo.
What should I do? Any tips how to fix this?
First try getting into Recovery mode & doing a factory reset & cache wipe.
If that doesn't work, try with a stock rom that's one prior to what you had before installing Arrow - like in this thread & follow the steps there (i.e. you first need to flash boot, system & recovery .img files extracted from the prior rom): [GUIDE] How to unbrick HUAWEI P8 when failed to update and ends in bootloop
If you cannot find where to download the prior stock rom, ask for help - someone may be able to provide a link that works. Tell us your phone's full, original model number (GRA-????), the region rom you need (e.g. C432 would be European) & the version B???.
Hi folks. I have the PRA-AL00XC675 (India) variant of the Honor 8 Lite. I recently updated my build to B151 and proceeded to root with Magisk. However, instead of patching a backup of my actual ROM, I extracted BOOT.img from a previous OTA update.app, I couldn't find one for my current build on firmware finder.
After flashing, my bootloader is still unlocked and it boots up, but is now stuck on "Your device is booting now..." screen. I appreciate any inputs to get my phone booting properly again. Does anyone have a back up of the Boot from a PRA-AL00XC675B151 ROM? Or know where I can find one?
hello!
i have a p9 lite vns-l21c432b380 dual sim
some days ago i contacted huawei to get the bootloader unlock code. after that i unlocked it via fastboot, flashed elite twrp recovery 3.2.1.0. everything working fine til now. i then tried to flash from twrp latest lineageOS release but it doesn't seem to be working as on reboot i get stuck on "you're device is unlocked and it can't be trusted" screen with the options to boot system and erecovery. it just stays there, no sign of lineage os.
i tried to restore at least the stock rom via dload and 3 button method and to flash extracted bits frome the update.app file via fastboot with no success: i always get a "update installation failed" error, with the only option to reboot the phone to nothing
what am i doing wrong?
update: i tried to flash oem info for l21c432 dual sim from twrp, then retried to install via dload and 3 button method. no luck, still "software install failed" and nothing else
OEMINFO: ftp://XDA-Dev:[email protected]/Oeminfo/L21/L21_DS_C432_by_EasySR.zip
FIRMWARE: http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1164/g104/v66034/f1/full/update.zip
i'll try to flash both via fastboot, since the recovery won't now mount data
thank you
fastboot gives me "command not allowed", flashing via elite twrp 3.1.1 "invalid zip format". what am i missing?
You need to flash oeminfo with TWRP. (Unpack the arhive then copy the oeminfo.img on your phone)
And also , unpack update.zip .
Then make a new folder on sdcard called dload and put update.app there.
Then boot into dload mode and it should work.
i'm not sure of how it worked. now i have TWRP 3.0.2 installed and stock ROM VNS-L31C432B150. some how it changed from l21 to l31.
do you think there's a way i can flash latest lineage os or should i stick to b150? in case how can i do it?
thank you for patience and time
Hi.
CAN-L11
Unlocked bootloader, rooted etc.
When i want back to factory settings, twrp show me information about encrypted data. So i vipe data (found this solution in google...) and when phone boot up there is error about unsuccesful decrypt data or something like that.
At next im boot into fastboot and flash by fastboot firmware boot, recovery,system and cust from update.app.
At now when i turn off phone i see only information "my phone is untrusted.... device is booting now" and nothing happens.
When i try to recovery firmware from sdcard (dload folder) it stuck at 5%.
What can i do ? I read many threads about that and there is many possible solutions but i dont wanna to make a bigger mess with my phone.
Sorry about my english
Unplug USB cable. Try another update.app?
DC-unlocker is a good solution bro, i had serious problem and i fixed and i get official nougat android,i have nova dual sim...
Okay, Let me explain exactly what I did here... I first flashed Twrp using SP flash tool which worked without too much problem. Then I attempted to install the latest super su zip which told me the boot.img was already patched and it could not find a ramdisk... So I moved on and flashed the latest Magisk zip which flashed no problem. Rebooted the device and it came up with a red boot state telling me it would boot in 5 sec. It did not boot at all. Turned off the tablet and rebooted into twrp again. I then flashed the OTA update system.img, boot.img, and re-flashed twrp from twrp itself instead of the SP flash tool. It booted into twrp no problem, however now it said it could not mount the system partition. I did a full data wipe, factory reset, rebooted into twrp again. Same issue. So I attempted to re-flash the firmware with SP flash tool. Did not notice i had it set to format and download and not only download. It said formatting for maybe 2 sec and gave me an error. Now the device will not turn on at all... no screen whatsoever, no recovery, etc... I have had no luck getting the asus flash tool to even recognize a com port however SP flash tool seems to be able to flash the device no problem. I extracted the .raw firmware file I have for the latest firmware, modified the scatter file to allow flashing all partitions, and I did a full firmware flash of the device using SP flash tool. However it still does not turn on... it does nothing... So I'm assuming that I accidentally formatted over the bootloader... And I cannot find a bootloader flash file for this device anywhere... So I'm stuck with an Asus ZenBrick... Does anyone know a way to fix this issue? When I plug the device into my computer and open device manager it switches between the preloader and mtk serial port very quickly not staying on either one very long. I'm assuming this is why I cant get the asus flash tool to work and SP flash tool works off just the initial preloader. I just bought this tablet from someone and managed to hard brick it in less than a days time... Any help at all with a way to revive this device will be greatly appreciated. Thank You in advance to anyone who tries to help me fix my mess up.
