Bootloop only when booting to recovery - OnePlus 2 Q&A, Help & Troubleshooting

I'm currently the running OOS 3 beta, and I want to change back to OOS 2.X, but the phone gets stuck in a bootloop when booting to recovery. I've tried booting into it both by holding vol down+power and using the adb command, I've also tried reflashing TWRP and stock, but the result is the same. Really weird tbh, I haven't done anything exotic with the phone, just trying out different ROMs. Any help would be appreciated.
Thanks!

All you did was that you updated your bootloader to the newer MM one by going OOS 3 and missed that you need to have a recovery that is bootable with the newer bootloader (think Linux Grub or Windows Bootmanager in terms, just a tad more sensitiv to what it wants to boot).
Just use search, your question has been answered like 100 times already.
And for the sake of god, where's the channel admin, cleaning is needed.

Help twrp

I have a Huawei P9 Lite and i have installed twrp and android 7.0 on it. Now I want to install Google assistant, but when i try to boot in twrp recovery (volume down + power b) it shows me the screen where it says ''Installing update'' and then freezes at 5 % so i have to hold my power button to power off the phone.
If I dont try to run in the twrp, phone works just fine.
I apologize for my bad english.
Hi there,
I will move your thread in the correct forum dedicated to Huawei P9 Lite for more relevant answers.
Good luck
Bump..
Just to state that I am in the same boat here; as I am facing the same issue. Here's what happened in my case (using a guide found here at XDA-Developers):
-- unlocked the bootloader
-- booted to bootloader and flashed twrp
-- used adb to reboot to recovery (adb reboot recovery)
-- used twrp recovery to flash nougat update (two zip files, one ~1300mb and second ~680mb)
-- had some errors that were expected, the guide said ignore them and reboot after both zips have been flashed.
-- the flash overall was successful as the phone booted in emui 5 with android nougat. However, there was no virtual keyboard; so decided to do a factory reset
-- rebooted to recovery, but this time, the phone booted to huawei erecovery
-- did a factory reset, but to no avail
-- now, i can't boot into twrp to flash anything else. booting into bootloader and using fastload to flash recovery image is successful, but the phone does not boot to twrp recovery; remain stuck on "your phone is booting up" (or something similar).
My phone is not bricked, as basic telephony, wifi and built-in apps are working fine. But, without a keyboard, its pretty useless for everyday use. Any help in this matter will be appreciated.

This seems helpful; but how can I flash recovery if I can't boot to fastboot?
[Update] Oh, got to fastboot, trying the suggested recovery now.
Fixed
Fixed using the suggestion above. Thanks.

P8 Lite turns itself off while booting to TWRP/CWM recovery

LATE EDIT: solved, read bottom of this topic for solution
Hi, so I have a P8 Lite and after properly unlocking the bootloader, I flashed TWRP (versions/ports found on XDA for P8 lite).
After using fastboot fastboot flash recovery twrp.img properly, it outputs OK, indicating it successfully flashed.
Now, assuming all went fine, I tried booting into recovery with powerbutton and volume up, after a few seconds only it turned off, the whole device just shuts itself down.
I then noticed it'd go into Huawei eRecovery when you keep holding it, so I just briefly pressed both keys until it started up, immediately released, and it still failed to boot into recovery.
To make sure I made no mistakes with triggering the recovery boot, I used adb to perform ''adb reboot recovery'' and so it attempted to boot into it, resulting yet again in the same black screen shortly after the Huawei (powered by android) logo, where that black screen is actually the device shutting itself down.
So the conclusion I draw is that the recovery is broken after installing it, the question is how. I'm not a novice to this kind of stuff, as you might have noticed, but still I cannot think of what went wrong, as my bootloader is successfully unlocked through the EMUI method, and I made proper use of fastboot to flash recovery, after which it tells me it succeeded, using the proper recovery for this device.
To double check I also installed the CWM recovery released for the P8 Lite (https://forum.xda-developers.com/p8...overy-clockwork-mod-recovery-cm-12-1-t3342209), as TWRP's for it (multiple versions/releases..) failed thus far, and also with CWM the same happens.
I really want to proceed flashing recovery to then root the phone and install a custom ROM, so any help or ideas what the cause might be, will be appreciated, or anyone that encountered the same problem!
SOLVED (was too lazy to post on time, i fixed it shortly after posting this).
The problem was that I flashed a bad recovery, basically the ALE-L21 has different TWRP versions advertised in the P8 lite section, i happened to choose a not too good one, it may have even been one that didnt belong to my model (like P8 lite generation year), not sure as the section is co-shared between P8 lite model generations, this mistake is easily made.
If you have this issue, just keep trying additional (TWRP) recoveries, the subsequent 2 versions from different publishers that I tried were working fine and the issue stopped.

Can't boot into fastboot or recovery after flashing custom kernel to the system image

I need some help.
Last night I was updating to lineageOS' new nightly update with TWRP in recovery mode. I also like to run a custom kernel on of that for battery life reasons. In doing so, I mindlessly flashed the custom kernel (blackscreen 3.6.2) to the system image partition instead of the boot partition, then went back and flashed SuperSU, wiped the cache as I normally do.
My problem is that when I rebooted the phone it hangs on the stock LeEco boot logo without going past it. In addition I cant get it to go into fastboot or recovery no matter what button combination I use. In addition, I can't get adb or fastboot to detect it from my PC to do anything from there either. My PC does detect a "Portable Devices", listed as a D:\ drive, but this isn't helpful.
I could really use some help. I'd hate to think I bricked my phone with such a mindless mistake. If you know what's up or another post that can help me, please post it.
Pls disregard this post, I managed to boot into recovery when I plugged it in to my PC and turned it on with volume up and power

Flashing S7E Exynos - Used Odin + TWRP, can't get any further.

Hi everyone, I tried to use this guide to root my phone.
Can confirm it's International, so Exynos.
Used Odin 3.12 and TWRP image 3.1.1 for hero2lte, which is the correct version.
Everything flashed perfectly - Got the OK from Odin, so can't see any problems that side.
Now the problem I'm getting:
When booting into recovery, I get installing updates... then 'No command' screen, like in this thread
I have factory reset via the recovery I DO have (I don't think this is TWRP, there's no touch interface, and it's all controlled via volume + power keys). This allows me to boot into the OS.
I have the option to boot into bootloader, and this takes a little while to do, but seems to fail and boot into the OS anyway.
I have no way of trying to reflash TWRP that I'm aware of, and I'm kinda stuck... could anyone help me from this point on please? Thank you!
EDIT: I'm trying to install custom ROMs and tweaks (Not sure if things like busybox/gravitybox/xPosed framework etc. exist anymore - haven't touched custom stuff for 3 years now! If you know, please let me know too!) So are there OTHER steps I should be aware of/know if I wanna proceed?
(just posting reply so I can see this thread later on, gonna do the same thing after exams, if I get same issue, this will be helpful)
P.S: By the way, when flashing TWRP, deselect auto reboot and see if you can go to recovery without booting it first. Sorry can't think of more options :S
after disabled auto reboot, then holding vol up and home and boot it booted to twrp.
Flash each of the checkboxes individually or it will send you back to download mode
Only one checkbox at a time also make sure ur oem unlock is enabled

LG H870 installing TWRP

Hi everybody. I need a little help here. I bought used LG G6 to practice installing custom roms. So I unlock bootloader and now I trying to install TWRP (at this moment without root beacuse obviously with my luck on my phone doesnt work any program like kingo ROOT or something like this) and when flashing recovery with ADB is done I unplugg smartphone and enter to menu with wipe all data because in every corner in internet I was people say when I choose ..Yes" twice then TWRP would launch. Not this time. And whats strange that when I boot smartphone normally then all the data is still on it. Power key+volume down doesnt do anything, volume up too. I dont know what to do next.
My answer may be too late but it sounds like the recovery you flashed is broken in some way.
When I installed my custom recovery I had to enter into recovery IMMEDIATELY after flashing the recovery image from terminal, in fastboot mode. Upon entering the recovery I had to install a .zip file named "no-verity-opt-encrypt.zip". This is the .zip that prevents the recovery partition to be reflashed by the phone's OS back to stock. This "back to stock" flashing is done by the OS at boot time. If you fail to boot into recovery and let the phone boot up before installing the .zip, you may have the experiences you just described. I'll search for the thread I followed.
Edit: Here is a thread I found useful:
Wich twrp actually work on h870?
Hello. I've been trying to get twrp(official) working on h870 for some time. The only version that at least boots up is 3.1.1.0 I know that in order to make it "stick" I have to flash magisk or custom rom. However I don't want to do that prior to...
forum.xda-developers.com
And here is the one I *probably* followed:
https://forum.xda-developers.com/t/recovery-twrp-v3-2-3-1-for-h870-h872-us997-unofficial.3828254/
Sadly I can't say 100% sure if it was the thread I followed back in the day.
