I am quite new to the android rooting & custom recovery and having a problem with my Huawei P8 GRA-UL00 flashing (purchased from China), when I try the procedure with MAC OS X. My step by step actions and result was as follows:
1. I installed "SDK Tools Only" for Mac. Connected the device via USB, launched terminal and successfully see the device with the "adb devices" command.
2. Vol +, Vol- and Power didn't work to enter to the fastboot&rescure mode. However, Vol- and Power worked. (Also, Vol+ and Power enters to the Huawei eRecovery mode, which shows EMUI logo, Reboot, Download new version and recovery and Shutdown buttons. I guess this is stock recovery???)
3. In the fastboot mode, I have successfully seen the device with "fastboot devices". Then I unlocked the bootloader with the code. The first problem was here, there were no auto-reboots and I entered "fastboot reboot" command, and stuck in seeing "reboooting..." in terminal. Nothing happened after this command. After 10 minutes I manually rebooted the phone by pressing power and entered into the fastboot mode. I was written as "Phone Unlocked". (Do u think it was really successful?)
4. I tried to flash the TWRP file which was uploaded by @jniklast (openrecovery-twrp-2.8.7.0-p8-ul10-r4.img). The result was like that:
MacBook-Airlatform-tools go$ ./fastboot flash recovery openrecovery-twrp-2.8.7.0-p8-ul10-r4.img
target reported max download size of 471859200 bytes
sending 'recovery' (25566 KB)...
OKAY [ 0.703s]
writing 'recovery'...
OKAY [ 0.353s]
finished. total time: 1.056s
MacBook-Airlatform-tools go$
5. Tried fastboot reboot, but I wasn't successful:
MacBook-Airlatform-tools go$ ./fastboot reboot-bootloader
rebooting into bootloader...
ERROR: usb_read failed with status e00002ed
FAILED (status read failed (No such file or directory))
finished. total time: 0.121s
MacBook-Airlatform-tools go$
I am not sure if I have correctly defined my problem. I guess I wasn't successful to install TWRP even it says so. What should I do after finishing the flash recovery command?
Can anyone help me with this error?
@landros57 That recovery is only for Android 5.1.1 beta version. You should flash the @jniklast 's GRA-L09 version of TWRP which is for Android 5.0.
I'm not quite sure what the problem is? You enter rescue mode via power + vol- so that's correct. You enter recovery via power + vol- and vol+ so what happens if you do that after flashing TWRP? And better not use the adb command go voot into recovery as that will lead to a bootloop to recovery which has to be broken by manually booting into it once.

Thank you samusalo.. Then I understand that TWRP for GRA-L09 can work on a GRA-UL00. I will try.

I don't use adb reboot, I manually press Vol - and Power. Then, the Fastboot & Rescue mode opens, and I enter to the terminal "fastboot flash recovery openrecovery-twrp-2.8.7.0-p8-ul10-r4.img". It quickly shows that the installation is successful. Then I enter fastboot reboot-bootloader (I guess this is required to launch TWRP) but it shows that usb read error.
@jniklast and @samusalo thank you for your explanations. They both worked.
I flashed the GRA-L09 version of the TWRP to my GRA-UL00 and it worked! Now I have a backup...
I also realized that I am doing something wrong.. After installing TWRP, I was trying to fastbot reboot-boatloader in order to get TWRP launched automatically. However, the only thing I need to do is to follow jniklast's instructions and after the phone shut down, press Vol+ Vol- and Power together to get the TWRP launch.
Now I will try to flash an official International ROM, instead of my Chinese ROM.
Is the following command correct for this?
fastboot flash system "HUAWEI P8 Firmware(GRA-UL00&UL10,Android5.0,Emtion UI 3.1,V100R001C900B141,General Version).zip"
No, you need to extract the img files to be able to flash it via fastboot. Look for huawei image extractor

Many .img files exists in the update.app file. I guess I need to flash only the system.img?
If I flash the recovery.img or boot.img inside the update.app, will I lose the custom recovery and my backup?
I'd first try to only flash system.img. If that doesn't work also flash boot.img. it might be though that you have to flash another cust.img as well and I'm not quite sure if that's possible via fastboot. In that case you'd have to do it via TWRP which is a bit tricky
Partially Successful

Flashing boot and system was successful! Then, again, my "fastboot reboot-bootloader" didn't work and retured me my initial error. But I rebooted manually and successfully launched my phone OS.
I now have a slow-operating new Android firmware, which is a little weird )) I think it is now a international&chinese hybrid version. Some apps disappeared and I have a complete new page for google services and apps. However, my chinese stuff (baidu spotlight search, notifications, etc.) remains The EMUI Build is: GRA-UL00V100R001C00B120, which should be V100R001C900B141 as I have flashed the img files of this update.
I tried "fastboot erase userdata", "fastboot erase cache" and "fastboot erase system" but they both returned with "FAILED (remote: Command not allowed)".
The following were my successful fastboot flash commands:

I was finally successful to flash cust.img with fastboot and now I have B141 and all Chinese apps are removed. All Chinese ROM specific apps are disappeared and the only remaining Chinese stuff is the text in the Magazine Unlock, accessible when swiped up from the bottom of the screen at the lock screen.
The remaining problem for now is; when I press the Dialer, Contacts and Messages apps at the bottom, they crash.
Do I need to flash any other from the following extracted img files?
3RDMODEM.img
CACHE.img
CRC.img
CURVER.img
DTIMAGE.img
EFI.img
FASTBOOT.img
HIFI.img
MCUIMAGE.img
MODEM.img
MODEM_DSP.img
MODEMNVM_UPDATE.img
RECOVERY.img
RECOVERY2.img
SENSORHUB.img
SHA256RSA.img
TEEOS.img
TRUSTFIRMWARE.img
USERDATA.img
VERLIST.img
XLOADER.img
This is now delicate stuff, you could try and flash the radio (aka modem.img) but that will probably break connectivity as that is different in hardware. Maybe you'd need to install the dialer and messaging apks from the ul00 firmware. Does an alternate dialer work so that you can actually call someone?
And I think fastboot reboot-bootloader doesn't exist. It's either fastboot reboot bootloader or maybe only fastboot reboot. Anyway, booting into bootloader or recovery is better done by pressing the keys on the P8

Hello again,
Actually the hardware is the same, it is GRA-UL00. The device originally had: GRA-UL00-UL10_EMUI3.1_Android5.0_C00B173
I tried to fastboot the following ROM:
HUAWEI P8 Firmware(GRA-UL00&UL10,Android5.0,Emtion UI 3.1,V100R001C900B141,General Version)
I was successful to flash Root, CUST and System but when I try to flash any Modem-related img files (Modem.img, 3RDMODEM.img, MODEM_DSP.img, MODEMNVM_UPDATE.img), I get the following error:
sending 'modem' (38865 KB)...
OKAY [ 1.038s]
writing 'modem'...
FAILED (remote: Command not allowed)
finished. total time: 1.039s
I didn't try to install APKs.
I am still having crash problems with the dialer, contacts, messages, google play, and some other google services.
Network Mode FREEZE AUTO
Hi did you try checking Mobile Networks In Settings, As i m unable to open that. As soon as i click on it the network gets released and then comes back. THATS' ALL. I have the same phone and did the same stuff. Unable to Flash Modem.IMG as well.
Finally Done!

I finally succeeded.
After flashing the Boot.img, system.img and cust.img and launching the phone, I flashed the stock recovery and made a wipe/reset to factory settings. First, I extracted the recovery.img from the update.app file which you can find after downloading the official firmware and running the Huawei Update Extractor script available in the forum. Then I flashed this stock recovery.img in the fastboot mode. And finally I entered in the stock recovery (Huawei eRecovery) mode by pressing the Vol+, and Power buttons. After the wipe & reset to factory settings, I launched the phone and all problems with the radio, dialer, contacts, google services, etc were solved.
Thank you @jniklast for your help.

Just checked and realized that I also have the same problem. THe contents of the "Mobile Networks" button doesn't show up and it works like a reset button. When I press, it disconnects me from the network and then the it reconnects to the network automatically.
Any Update on this anyone? I am unable to use the phone as it drains a lot of battery on 3G and i cant change it to 2G as due to Blank Mobile Network Settings.
Guys I have one problem I want to flash stock recovery for P8 L09 but in cmd it fails like not allowed command anybody knows why ?

Hi landro57 have you tried to flash the update.app file of 18 Kb from local update? Some owners of the P8 gra ul09 variant are using that file to debrand their P8s. The mobile networks problem you ae experiencing is the same some other people have turnaround with that trick. You should check with it and report back to us, because if that goes ok, it means no more china firmware on our P8 gra ul00, we can simply flash the international general P8 firmware V100R001C900B141.

Hi GryphonA, I don't get it, which 18kb update.app file do you mean?
I got the same problem (no access to mobile networks settings) and I can't remember if I never had that access or it happened due to my rooting/cusomizing activities.
I have GRA-UL00C433B180. I flashed also C470B180 but that didn't solve the problem.
BTW: There are a lot of mobile network setting apps and widgets in the Play Store but all apps I tested show the same failure as the mobile network settings: There seems to be a network reset and nothing more.
I originally did a boot unlock, a fash of twrp-2.8.7.2-angler.img, and when I could not get the pattern on twrp recovery to function, I did a sideload of the twrp.img instead of an install.
This failed in a boot loop.
SO I did a flash back to stock with angler-mdb08m-factory-dbc17940.tgz (after unpacking this).
Then I restored all my apk, etc.
BUT now when I do:
fastboot flash recovery twrp-2.8.7.2-angler.img, I SEE:
target reported max download size of 494927872 bytes
sending 'recovery' (16880 KB)...
OKAY [ 0.561s]
writing 'recovery'...
OKAY [ 0.247s]
finished. total time: 0.809s
---- all looks fine, but the device itself does not seem to react and when I reboot, and select recovery, it just goes into Google recovery.
Has anyone else seen this, and do you know how to get past this?
I already tried to unlock again and it tells me error, already unlocked.
So my next step would be to do a lock and then an unlock again, but that would probably cause me to take several hours restoring after another flash to stock, and I fear that I will be back where I am now??? any thoughts??
SOLVED!
It seems that somehow, I just hadn't waited long enough. I was able to now reboot into recovery.
Thanks to any that looked at this issue.
Hi all,
I understand there is loads of this stuff online but found nothing related to Z1, please bear with me. So, after successfully installing TWRP my Z1 is always loading the cm recovery.
I'm with CM 12.1 yog4pap25i, update CM recovery is off.
After flashing TWRP is there specific actions I need to do? I've always rebooted into recovery with fastboot or the advanced reboot in the phone, but I'm always having CM recovery installed.
Thanks for your help

You unlocked bootloader and checked oem unlock im sure.
But which command did you use to flash the twrp?
Output should be like this:
C:\Users\anwender\AppData\Local\Android\sdk\platform-tools>fastboot -i 0x2b4c flash recovery recovery.img
target reported max download size of 1610612736 bytes

OKAY
Please post your output
Hi @strongst, I'm on mobile now but yes, the response is ok. Also I've checked what you suggested. The problem is I think I did everything well, but somehow I'm not rebooting correctly
after that command type fastboot boot twrp.img (twrp is the name of recovery img) and it will booted into recovery

I would say, after installing twrp, directly type fastboot reboot recovery and boot to recovery immediately.
Booting into system will replace the stock recovery

Hi, this is the message received after flashing:

then I digit this
PS C:\platform-tools> fastboot reboot recovery

if i switch off it is booting automaticaly into CM12. If I exit the shell and try power + volume down it opens a plain recovery, neither the CM revocery nor the twrp. Any idea of what I'm doing wrong?
edit: also tried this
PS C:\platform-tools> adb devices

hi everyone, sorry for the newbie question above. Eventually I've managed to install TWRP, I just missed the right key combination to reboot.
Thanks
I'm trying to flash and start the TWRP. I've already done this once on a LG G6 (h870).
I downloaded TWRP from there: twrp.me/h870
Code:
OEM is unlocked:
fastboot getvar unlocked
unlocked: yes
Code:
fastboot flash recovery twrp-3.2.3-0-h870.img
Sending 'recovery' (21420 KB) OKAY [ 0.911s]
Writing 'recovery' OKAY [ 0.190s ]
After the flash, I start the recovery mode by pressing the button combination. After that I get the factory reset request, -> I choose 2x "yes".
The LG logo appears and then the splash screen of TWRP. But instead of getting into TWRP, the screen gets dark again and the phone restarts in the system.
I didn't find the same problem anywhere in a forum. Does anyone know what I can try to do to successfully start TWRP? Thank you for your help!
Unlocking again did the trick

For whatever reason, this was the solution:
Code:
fastboot flash unlock unlock.bin
Good news ...
I had the same problem as you with TWRP 3.2.3 H870 and i finally used the "unofficial twrp" developped by RunningNak3d" ...
In other words, you unlocked your phone twice !!!
Did your unlock it a second time, then flashed the TWRP official again OR did you simply flash a second time the unlock.bin ?
And this way, do you still have the "infamous" WARNING screen about bootloader locked made in Google ?
