TWRP gets overwritten

I'm on latest ob18. I am able to flash it, and run it once, but after reboot, the stock recovery gets Back. Any ideas?

Just Reflash twrp via flashify or adb in fastboot mode, that could be normal if u r flash an unmodified stock rom

Yep. On latest ob-Oos or H2o for me recovery stays, after instaltion of the rom. But on a second reboot, stock recovery shows and i reflash custom recovery again.

Guys I flashed latest H2OS beta over OOS Beta18 and lost access to recovery. These are the steps I followed, please help.
1. Backup current ROM (OB18)
2. Dirty Flash New H2OS version
3. Flash recovery image again
4. Reboot system
ROM booted without any problems and all my data is present but I lost access to TWRP.
Solution attempted: Reboot to fastboot and flash recovery image again, the process is successful but still TWRP is not coming up.
Please help. Thanks in advance

Stock rom always over writes recovery best way to get it to stick is flash stock zip than twrp reboot to twrp and reboot or flash mods/root

Thanks this worked

[SOLVED] HELP! i'm stuck in a boot loop! :(

my flashing history:
i was on audax (oos based nougat rom) with blu spark kernel before, then went to official ob1, then back to audax, then back to stock oos nougat and now i flashed audax and after clean flashing it, it just wont boot up.
when i try to boot up i see the 1+ logo but then it reboots to recovery. i also tried flashing stock nougat again and also flashed stock kernel manually but it also doesnt work.
i always do:
1. wipe system/dalvic/cache/data
2. install ROM
3. wipe dalvik/cache
4. flash magisk (also tried without flashing magisk)
5. reboot
i've been looking on the interwebs all day but nothing worked.. help pls :/
EDIT: problem was blu spark twrp. Maybe installing Oreo ****ed it up. I flashed codeworkx newest twrp universal build and now Im able to boot again!! Btw: I also found that magisk 15.0 prohibits a proper boot up and results in a boot loop. version 15.2, however, does the trick!

when it auto reboot to recovery, formate data

When s**t happens, it is wise to start everything from scratch:
-boot in fastboot mode and flash stock recovery with "fastboot flash recovery recovery.img" (rename recovery.img with your recovery filename), then reboot recovery and select english, advanced, adb sideload;
-flash stock OS with "adb sideload rom.zip" (rename rom.zip with your Oxygen OS filename).
Procedure will require some minute because of the large file size. Remember to save all your data on internal storage first!
I advice you to flash original recovery because often sideloading in TWRP leads to some error.
Your phone will boot again... after that you may reflash TWRP, Magisk etc

I had the same issue. Bootloop and jumb into recovery by itself. You have to flash magisk 15.2 via recovery and will be boot.

He says that it occurs even without Magisk... I had a similar trouble once, and the only way to solve it was the procedure I wrote above...

I dont know if you can boot it w/o root

Why not? Stock OS is not rooted.

SOLVED! TWRP was the only variable left that I didn't think of. See initial post for solution. thx for help!

Help!! My Pixel 2 XL is stuck in the bootloader!

Hello, I was just trying to install a custom ROM (Resurrection Remix) on my phone, but now I can't get out of the bootloader.
The steps I took were:
Install TWRP
Root with Magisk (for Titanium Backup)
Factory Reset in TWRP
Flash the RR rom zip file
and now when I turn my phone on, it goes through the bootloader unlock notice and the Google screen, but then it just goes into the bootloader.
I tried going into LineageOS recovery and doing an OEM sideload, but when I go into Apply Update --> Apply from ADB, on my computer, adb devices shows nothing.
Someone please help me.

So fastboot should work. You can always flash the stock ROM first and continue from there.
Instructions: https://developers.google.com/android/images

Try the following,
Go back to stock
Boot twrp
Swipe to factory reset in twrp
Flash RR ROM zip
Flash TWRP zip
Boot to system (it should go to OS)
reboot back to TWRP
Flash custom kernel (optional)
Flash Magisk for root
Boot back to system

Oneplus 5T root problem

Hello all If any one can help me ,
I was rooted running rooted stock oxygen os before on my Oneplus 5T
after flashing Oxygen OS 5.1.4 Full Zip my phone is not rooting it gets in initial oneplus logo and freeze there without loading OS
Phone is working fine after Flashing Oxygen OS 5.1.4 Full Zip without any issue its not booting after flashing either SuperSu or Magisk
Steps which I follow are
1 Flash custom recovery I have tried both Codeworkx TWRP | Blu_Spark
2 after flashing recovery boot in to recovery flash Supersu or magisk
3 reboot
when I reboot if i Flash supersu it stuck on oneplus logo, If i flash magisk it reboot itself to fastboot so Os is not loading at all.
I have to flash full Zip again every time to get it working but then I dont have root access.
I have tried at least 10 times with different even old versions of magisk and supersu with out any success.
Is there any particular recovery or different version of magisk or superuse I need to flash?
your help will be really appreciated.

Try a different approach. Instead of installing recovery, just get phone rooted first. There is a way where you can boot into twrp (without installing it), and then flash magisk/supersu zip. If your phone is rooted, then you can install twrp later (or keep oem recovery)
This is how you boot into twrp (or any recovery): fastboot boot recovery recovery.img
Let me know how it goes.

As you said boot to recovery without installing it.
One problem currently I am installing recovery and flashing root. After that phone is not booting up in to OS it stuck on oneplus logo. Then I have to force off phone boot in to recovery and flash full os zip to get it working. I can boot in to TWRP because my os didn't load. Now if I use your method and flash root file and if phone won't boot to os that means I won't be able to boot in to TWRP again to flash full os zip to get phone working atleast without root. Any idea?

Huh, frankly I have no idea why you are facing this menace. I can just give two suggestions.
1. Try with older, more stable versions of TWRP and Magisk
2. Get yourself a custom ROM, most ROM's will work flawlessly after flashing root files
Hope for the best!

I usually switch from OpenBeta to LOS and back again. Here's how I switch back to OpenBeta (steps should work for official OOS):
1) Back everything on internal storage up. This one's important
2) Boot into official OOS recovery
3) Wipe EVERYTHING (this is why you need to follow Step 1)
4) Sideload the version of OOS you want. The instructions will be right there on the recovery screen
5) Boot into Fastboot and flash TWRP
6) Flash Magisk and (optional) Xposed

All the usual preemptive steps are complete, correct? You OEM unlocked it and all that?

Don't feel too bad my friend, the P2XL is a quirky little bugger to say the least. I had a heck of a time rooting 9.0 after I updated from 8.1, then outa the blue, it worked. Here's a few steps to try.
1. Fastboot twrp, then flash magisk, try to boot.
2. Fastboot twrp, flash twrp.zip, boot up, then go back to twrp and flash magisk. If no go, do the same steps, except after you flash magisk, flash the magisk uninstaller zip, then flash magisk again.
3. Fastboot into twrp, flash twrp.zip, custom kernel.zip, then magisk.zip. if no go, then try the magisk uninstaller.zip method again.
4. Stick with it, be patient, sooner or latter you'll find the right combo. Also, it seems easier to root using a custom kernel, if your willing to try it :good:

Maybe give the guide linked in my sig a shot.
If that doesn't help, try the following:
-once you've permanently installed TWRP, try rebooting to recovery after each additional step BEFORE rebooting to system:
install cust kernel, reboot to recovery, reboot to system
install magisk, reboot to recovery, reboot to system
if that doesn't work, try doing a mass install after TWRP is permanently installed:
in the same flash, install cust kernel and magisk, reboot to system
These have helped other users who have had odd issues with their set ups, but in the end, Pixel 2 XL is a fickle beast
Best of luck!

SOLVED
The only way (for me) to root my Pixel 2 XL is follow theese steps:
Rooting with Magisk
NOTE #4: This section assumes you are not going to install TWRP. If you are, skip to the next section and just flash the latest Magisk zip after installing TWRP.
Download the Magisk zip from the official thread and install the manager from the zip.
Grab a boot image to patch (either the one from the latest factory image or a custom kernel one) and push it to your device:
Code:
adb push <path_to_file> /sdcard/Download
Open Magisk Manager and click the Install button.
Click "Install" at the first prompt then choose "Patch Boot Image File". A file manager will pop up.
Select the boot image you want to patch and let Magisk Manager patch it.
Pull it off your device:
Code:
adb pull /sdcard/MagiskManager/patched_boot.img
Reboot into the bootloader:
Code:
adb reboot bootloader
Flash the boot image and reboot.
Code:
fastboot flash boot patched_boot.img
fastboot reboot
Open Magisk Manager and you should be rooted!
