Was your ROM compatible with TWRP 3.1.1, have you checked OP on the 1st page (e.g., you must have had EMUI 5)
https://forum.xda-developers.com/p9/development/twrp-t3565703

YES TWRP was for NUGAT...
Reflashed stock rom via TWRP helped in my case and my beatiful P9 back to life.

Hi!
Yes, there is

I've tested it
There is TWRP 3.0.0, http://forum.xda-developers.com/ascend-p7/orig-development/recovery-t3314665
but I haven't tested it
I have the 3.0.0 installed, working well

TWRP not installing

Hey folks,
I've been trying to install TWRP on my Mi5, MIUI 8 Global 7.1.19 Beta, and I cannot, for the life of me, get it to work.
I've tried the standard method via Fastboot, which boots into TWRP but then defaults back to the standard Xiaomi recovery when I reboot. I've scoured the MIUI forums and these forums here and tried the solutions suggested, such as the Cofface.img and Flasher toolkit (When using the toolkit it says it has completed successfully and says "you are now in TWRP xxxxx" but the device remains in Fastboot mode and doesn't even reboot) etc., but none of them work! Each and every time the device falls back to the standard recovery and I'm left with more grey hair.
Does anyone know of any other solutions or ideas?
Thanks in advance.
What TWRP version ?
Did you try the modified version that is available in the miUI forum? xz.. something...
There is also a guide for it (on the miUI).

Cheers for the info, mate. Yes, I've tried the modded version (the cofface version and TWR 3.0.2.X), 3.0.2.1. wouldn't open when I was able to boot into it (once), it just stuck at the splash screen and 3.0.2.0 won't even boot, let alone install.
Cheers mate!
TWRP is now at 3.0.2-3
This is the webpage (official twrp site):https://twrp.me/devices/xiaomimi5.html
The modified version is the ZCX-TWRP: http://en.miui.com/thread-364569-1-1.html
Thanks! I managed to boot into 3.0.2-3 to flash the EU ROM I wanted. I'll have a quick reboot now and see if the recovery has stuck.
Edit
Yep. I managed to boot into 3.0.2-3, install the ROM and the recovery is fine too. Cheers, man. I appreciate the help.
Same problem...
Console tells me everything is well but there is no twrp... Tryed newest version.
Never mind. Had to boot into TWRP as a last step.
"adb reboot recovery"

TWRP wont run on P9

I recently installed twrp eva 3.0.2 on my P9 L19C636 but it wont boot into twrp. It gets stuck on your device is booting now.
Thanls
Not every recovery can run on any firmware. If you are on the newest firmware (N) try the newest TWRP 3.1.0-0.

For stock rom try the newest superuser or if it doesn't work the pre-rooted boot image from this forum. (flashed via fastboot)
For me I had no success with the superuser install for some reason but the boot image worked.

Tried to flash twrp. Can't boot into recovery anymore.

Hi i tried to root my P9. I unlocked the bootloader successfully and i can flash the recovery but i can't boot into recovery anymore. I get stuck on "Your device is booting now...". Also i tried to flash twrp onto recovery2 which is often suggested and that didn't help either. What i find weird it that adb doesn't allow me to erase a partition "FAILED: (remote: Command not allowed). Also the phone still works normal and i can use android. I also tried to flash a stock recovery but that still doesn't boot into the recovery. I couldn't find any advice online that would help me further. Hope someone can help me out.

You probably flashed incorrect TWRP -
you didn't even mention are you on MM (EMUI 4) or N (EMUI 5)
Different TWRP images must be used, but from the corresponding XDA Huawei P9 (MM or N) threads - not something maybe from elswhere on Internet
Also, if it didn't work from Recovery then no chance that it would work from eRecovery (if wrong TWRP, not ported to Huawei P9 and your EMUI version, it will not ecognize partitions and encryption, no matter if flashed to Recovery or eRecovery)
For example, if you didn't spoil also eRecovery, you would be simply able now to (re)Install latest firmware and recovery from eRecovery, and it would fix your stock Recovery
Otherwise, you should flash Recovery and eRecovery (extracted by Huawei Extractor from update.app, unzipped from FullOTA update.zip corresponding to your exact stock firmware and build you have).
Or, reinstall your stock firmware by DLOAD method (FullOTA-MF-PV package must be used for DLOAD)
You can also just flash the correct TWRP (but I strongly recommend to recover the stock eRecovery anyway), find the correct ports for MM, N and O here:
https://forum.xda-developers.com/showpost.php?p=72153575&postcount=2
https://forum.xda-developers.com/showpost.php?p=75787111
https://forum.xda-developers.com/showpost.php?p=77161313&postcount=2
If you are on Nougat, you can also find on XDA (actually, zipped in HWOTA/HWOTA7 packages from links 2 and 3 above) the so-called no-check Recovery, it can replace Recovery (but not eRecovery) img for any EMUI 5 stock firmware)
---
Btw, for Magisk (root), you don't need TWRP. Just install Magisk Manager app and patch your extracted Boot.img (MM and N, on Oreo Ramdisk.img), then flash the patched img from Fastboot

TWRP.me (apparently) is the official TWRP site but you can see that they only have one TWRP img file (for each new TWRP release) for Huawei P9 (EVA) - hence they don't care, they are not aware of different organization of partitions (sizes, names and encryption) coming with different EMUI versions.
And from their P9 Changelog (screenshot attached) you can see that last adaptation for P9 was made in May 2016, when P9 had its original Marshmallow (EMUI 4).
Below is XDA thread from 2017 when Nougat (EMUI 5) was released and a guy who ported to (with description of changes he made). TWRP for EMUI 5 I gave you the link in previous answer is based on his port, but made after he stopped maintaining it (he moved off from P9), hence it is still TWRP 3.2.1.0 but with slight change (somebody else fixed/improved I think which partitions are mounted by default and/or what will be erased by Factory reset option - I don't recall details anymore)
https://forum.xda-developers.com/p9/development/twrp-t3565703
Btw, you are not the first who soft-bricked P9 (with Nougat) by installing the 'official' TWRP (you could search here on XDA P9 sub-forum, I recall I similarly helped to two or three of them last year and this year) and who had to move to the proper port from XDA to unbrick - the 'official' TWRP seems to be good only for those who are stuck with Marshmallow / EMUI 4 from 2016 (most likely those who got stuck with the cust c900, 'international' cust at that time, that was never updated by Huawei to Nougat while they introduced new custs for different world regions, countries and operators when they started to sell and support the phone out of China)
It would be fair if TWRP.me at least makes a note on which stock firmware version they test their 'official' P9 releases...

Can't access twrp 3.4.0.1, H870

Hello,
I've installed twrp 3.4.0.1 via fastboot, but after I select yes when i'm asked about erasing my data, the phone just boot up normally without deleting any of my data, but does not enter twrp either. Tried 3.4.0.0 too, no luck. Only 3.3.1.0 worked, but when I try to backup it says something like 'can't mount system partition' and some other errors. I think that version is too old for my rom, so I'm afraid to use it for backup/flash. My phone is LG G6 H870, Android 9, software version V30b. The phone is not rooted, the bootloader is unlocked. Tried to erase cache partition and install twrp 3.4.01 again, didn't work. I can't install Skyhawk or Orangefox becuase I can't use twrp.
Is anybody facing this problem too?
Thanks!
Bootloader unlocked?

HI You need to use OrangeFox recovery or SkyHawk. If you plan to go to 10, then you need SkyHawk. And I think SkyHawk is maintained but OrangeFox not.
Links:
SkyHawk https://sourceforge.net/projects/pa-g6/files/Releases/SHRP/20.07.2020/H870/
OrangeFox https://forum.xda-developers.com/lg-g6/development/recovery-orangefox-recovery-project-t3943594

So can I install SkyHawk via fastboot over stock recovery without installing twrp beforehand? I see there are multiple files in the shyhawk zip, should I only extract the recovery img and install it via fastboot? I'm kinda new to this, thanks!

HI. It is made to flash in TWRP (same as OrangFox) So I really don't know if that recovery.img flashing through Fastboot works. Never tried, sorry.
Maybe someone knows though.

Ok, thanks, I'll try to find a solution, or maybe I'll just wait for the next version of twrp.
You should try installing the recovery and immediately installing any custom rom, when i flashed twrp the first time i had to do it several times cause somehow it got "erased" every time i noot the stock OS.
Ig you don't want to install a custom rom try right after installing twrp and on the fastboot screen to reboot to recovery with (Volume - ) button and power.
I think the idea is not letting the Stock os boot
Also that error. i have the same problem, the only moment it doesn't appear is when you wipe all data with the "Format Data" option inside "Wipe" menu in twrp.
After you boot to the OS once and go back to recovery it will come again everytime you flash something.
Not sure if its a problem or not, because i've dirty installed some updates and also installed gapps and magisk even with that error.
Im currently in A10 using Havoc and NikGapps.
TWRP 3.2.3-0

Yes, I know I have to install twrp again every time I let the stock rom boot, but the only version of twrp working is 3.2.3 and I think that was released before the G6 received official Android 9 update, so that's why I'm not very confident using it. I've tried to enter recovery immediately after I've installed it, so I don't think that's the problem.
I have the same problem on the LG G6 H870. I won't get to TWRP. I tried several versions of TWRP and nothing.
Edit.
This twrp is functional:
https://androidfilehost.com/?w=files&flid=289997
After installation using fastboot, restart directly to twrp using power+vol. down.
Finally i've successfully flashed Skyhawk using TWRP 3.3.1, so thanks everyone for advice!
Still couldn't make official TWRP 3.4.0/3.4.0.1 work.

Hi, I don't know if this goes here, I hope you can help me, I update twrp from version 3.1 to 3.4 and now I can't access twrp, how can I fix it?
Hello again, I answer myself, and if it helps someone else, using adb fastboot with twrp 3.2 Melina solves it and twrp works perfectly again.
