(fixed )Another phone brick. Only eRecovery showing up - Huawei P9 Questions & Answers

hello!
I have the EVA-L09 version of the P9, and I recently had installed Cyanogenmod 13 on it.
To do that, I needed to do an OEM unlock and flash TWRP ++.
Now when I'm trying to go back, I can't get my phone to force the update from the DLOAD folder.
"Volume up + power" and "volume up + down + power" does both enter the eRecovery. I've tried this from rebooting my phone by holding down the power button, and also entering the eRecovery and pressing "shut down" first.
I've tried to flash the recovery.img and recovery2.img from my B136 firmware (UPDATE.APP) - but i can't get it working.
I have also tested with unlocked and relocked bootloader.
What do I simply do to make it work?
Where do i find stock recovery that works? gah
EDIT: Fixed it by following the steps provided here. Just note that phone has to be powered completely off, before you hold down all buttons to boot into recovery. http://forum.xda-developers.com/showpost.php?p=67754200&postcount=4

Can't go into fastboot mode. Please help!

Hello. I have a razr I and decided to unlock the bootloader. I tried the button combination power + volume down several times, but the phone just powers up normally (actually rhe screen flashes for a second, but doesn't go into fastboot mode. I trided using adb reboot fastboot but the device just reboots. What can I do about it?
NVM, just did it by fastboot reboot bootloader...
Ok, one more thing. It seems my device ignores the key combo, but I was still able to get into fastboot mode by using adb. However, I have tried to flash a custom recovery with no success.
I tred using the supplied installer and after rebooting I get to the open robot screen with the red exclamation mark. Then, after holding some keys (not sure if power or power + volume down I get into recovery, but it's still the stock android recovery. Then I tried flashing the recovery image from fastboot mode. It sait the recovery was flashed, but still cannot boot into recovery. What's wrong with my phone?

Just incase you need to do it in the future:
Hold volume down, then hold the power button. When it begins to vibrate release the power button and keep the volume down button pressed until you get into fastboot.

Alright. So how about the never appearing CWM recovery?

How to run TWRP on P10 VTR-L09?

As a newbie hoping to root my P10, I have just entered a magical world that is confusing to me. After reading many posts about installing TWRP on the P10, I have no success running TWRP: all I get is the stock EMUI recovery.
Am I missing a secret maneuver?
This is what I did:
1. Unlocked
2. Powered Off and On
adb reboot bootloader
fastboot flash recovery twrp-3.1.1-0-vtr.img
3. Power Off
4. Try to Power On with Power + either Vol Up or Vol Down for a few seconds
Each time, I get EMUI Recovery instead of TWRP.
Would love some insights on that. Huge thanks in advance for any gentle guidance you can give.
Try to unplug the usb before you boot into recovery.
This should work.
To get root use the magisk tutorial. It's the safest method and you can hide it from apps.
Thank you for your advice, @Hamburg.
Oddly, the device still boots to EMUI Recovery instead of TWRP.
Same when I use
fastboot flash recovery twrp_3.1.1_fromfuture.img
First there is a screen that says that the device is unsafe because it has been unlocked, and to press the Up Volume for three seconds to enter recovery. That's when it boots into EMUI Recovery.
Shortcut combination is tricky to enter recovery, it usually require several attempts to get it right. With these devices, after logo, it is vol down + power again if I do not remember wrong (not just volume). Check the button combination again, just I case
Don't press the volume down button when the bootloader screen tells it.
Start the phone with this instructions:
Press and hold the power button until the phone vibrates, press and hold volume down and release the power button.
Hold the volume button until twrp shows up.
The Bootloader screen will also be present but will show you something linke "booting recovery" instantly.
If you get to the UI you can also boot into TWRP with the ADB and Fastboot Tools "adb reboot recovery".
I flashed TWRP 3.1.0 and it worked fine.
Maybe you can also start the recovery image from Fastboot directly by "fastboot boot recovery [VariableNameofTWRP].IMG"
Thank You!!!
Thank you so much @Jannomag and @ChipCollector !
Both of your instructions work (on my phone with Volume Up instead of Down).
In case someone else is reading, here are the full details to load TWRP on this particular phone.
1. Unlock
- get unlock code from https://www.emui.com/en/plugin/unlock/detail
- adb reboot bootloader
- fastboot oem unlock UNLOCK_CODE_FROM_THIS_URL
2. Install TWRP
- Remove cable, reboot, plug in
- adb reboot bootloader
- fastboot flash recovery twrp-3.1.1-0-vtr.img
( substitute your image name, e.g. twrp_3.1.1_fromfuture.img )
3. Run TWRP
Unplug, power off, then EITHER
- Remove cable
- First Option:
--- reboot, plug in
--- adb reboot recovery
- Second Option:
--- press Power until the phone vibrates
--- immediately press Volume Up and hold, quickly release power, keep holding Volume Up until the TWRP screen appears.
Now I'm at the scary place where I have to do make the right choice and not brick this thing.
The question is answered, so I will ask my next question in a different post.
Huge thanks!!! :good:
Hi guys, who has a working link for a P10 (Emui 9) TWRP image?
Thank you in advance

Can't access TWRP even though it's installed, loads huawei recovery instead of twrp.

Hi guys,
My firmware is stuck on emui 4.1 and I'm trying to install a custom Rom.
Bootloader unlocked fine
adb worked fine
I've flashed twrp
However, whenever I try to reboot I get the "your phone can't be trusted" boot recovery screen instead of TWRP, so I can't root.
I've tried power and up, power and down, and power and up and down.
They either go to the recovery option screen, then boot like normal, or hangs on the normal boot screen
Any suggestions
Things repeated several times elswhere.
1. Your phone cannot be trusted because you unlocked the bootloader. If you don't like it, re-lock bootloader ;-(
2. Upon flashing TWRP, FIRST THING YOU MUST DO is rebooting to TWRP. If you don't do that, stock Recovery will ovewrite TWRP.
Find instructions in the TWRP threads how to enforce immediate booting to TWRP, upon you flashed it:
-Type on the PC: fastboot reboot -but don't press Enter yet.
-Press and keep pressing Vol+ and Power buttons together on the phone
-Press Enter on the PC and then immediately unplug USB cabel.
-When phone shows Booting, release Power but keep pressing Vol+. button

Trouble getting TWRP installed

Have a SM-T813. Attempting to use Odin to flash TWRP. All goes well be it keeps rebooting back into the normal recovery. I've tried different methods....with and without auto-reboot. I've read where some devices will replace the updated recovery if the proper key sequence is not used but I think that may be part of the issue. When done flashing I hit the power button and vol down button but instead of powering down it seems to power back up/reboot precluding me from hitting the proper key sequence to enter recovery mode. Home + Vol UP + Power.
And btw I have Allow OEM Unlocking and Allow USB debugging set.
Am I missing a procedure?

I have a 713 and the procedure is kind of funky but is the same. See lines 5-7 below. You literally need to move one finger from volume down to volume up while the fingers on power and home stay put.
https://forum.xda-developers.com/tab-s2/development/twrp-3-0-2-1-galaxy-tab-s22016-sm-t713-t3390627
Flash with ODIN 3.10.7 in the AP slot.
Put your device in DOWNLOAD mode.
Uncheck Auto reboot.
Load the respective file below into the AP slot and hit start.
After flashing and ODIN reports PASS immediately reboot to recovery by holding POWER + HOME + VOL DOWN.
As soon as the screen goes blank change to VOL UP whilst still holding POWER + HOME.
You should now see TWRP recovery.
Yep finally figured out the one finger deal from vol down to vol up. Installed and working fine now.

Stuck In Bootloop (Not able to get in fastboot or recovery mode)

My device went int bootloop suddenly while I was using it. I not able to get in fastboot (when I press Power + Down it shows fastboot window for a sec and reboots again ) or recovery mode(When I press Power + Up, Screen shows up saying no command).
I was using official build(July patch). I have not enabled ADB. My bootloader is also locked.
Is it possible to get this device working?
Any help will be appreciated.

This is normal behavior of stock recovery: seeing "no command" hold "power" and click "Vol+", - to get to the stock recovery menu (btw, search would 100% give you this tip even in these forums).
As you are locked, and thus you have surely lost user data, you can try to make factory reset from recovery menu.
Yet I'd try to connect phone to power and make numerous attempts to reboot, occasionally rebooting into fastboot and into recovery, - with the hope that phone will switch into the other A/B slot.
If nothing helps, TestPoint/EDL is the only option except service.
But again, the problem may be hardware issue, and as you are supposed to disassemble phone preforming TestPoint, I'd check connectors inside and tried to reboot again before reflashing in MiFlash. And do not forget to reflash in fastboot after MiFlash reflash (and unlock phone - which I did immediately after purchase).
