failed to flash ob 10 and can only boot into recovery now

Tried to flash flash ob 10, but twrp said the zip was corrupted. I could not boot into the system anymore.
The problem is the system partition is ok ( verified from twrp file manager), but every time I choose reboot system, it will go back to twrp. I tried to re-flash ob 9, but twrp again reported another error. Log is attached. How should I solve the problem?
By the way, I wipe all data, including storage in twrp by mistake. Is there any way to recover the data? I am traveling now, just got several hundred pictures.:crying::crying: It seems to be impossible to do it on a computer in MTP mode, but I could not boot into the system neither.

Download the modded twrp from here and install it. Use it to flash community builds and all other roms from now on.
About the file recovering part, I wouldn't know.

You need to flash stock recovery, ADB sideload the official Open Beta, and boot into ROM.
By any chance, did you trigger an OTA update with TWRP installed?

I am always using the modified one. I am encountering a weird error.
The message is like
'E: unknown command [log]
........
script succeeded: result was [1.000000]'.
Update: flashing stock recovery seems to be effective ( of course, twrp does not exist anymore ).

Unknown command is a known and harmless issue on all 7.x.x roms. Just ignore it and go ahead.
And I think I saw 3.0.2-1 twrp version in your log.

Open Beta builds can be flashed via modded twrp, no need to use stock recovery and adb sideloading. Plus even if he installed an OTA update, it won't get installed on twrp ~ and no harm will be done.

After you flash any rom, reflash recovery. Reboot to RECOVERY & then to system.
The red message it's on almoust every Nugat rom. And it's about some log .

He said he could only boot into twrp. That occurs (reboot to system will take it back to twrp over and over) only if someone tried an OTA update with twrp.

I don't think this is the case for you, but if you tried the other suggestions don't work try the below. I had a similar issue and found that my recovery partition was corrupted. However, an additional symptom I had was that my TWRP would hang completely when selecting reboot after any successful flash. I think modded TWRP does not like internal storage wipe from within TWRP (rather than through fastboot format userdata).
Boot to fastboot
Fastboot erase recovery
Fastboot flash recovery filename.img
Boot to recovery and flash your desired ROM+supersu which you can sideload via MTP (drag and drop from Windows) or adb push C:\SourceLocation\filename.zip /sdcard
I recommend ADB push over MTP.

Had the exact same problem as op, after some issues i was forced to use the unbrick method to get phone back as it wasn't even booting. Now im using beta 10 perfectly.

Did you manage to fix it? I have the same probem.

TWRP New install , New Phone issues fastboot

Did standard unlock bootloader (went fine)
Moved a TWRP zip onto phone sd root directory (twrp-3.4.0-0-guacamole-unified-Q-mauronofrio.zip)
adp fastboot boot twrp-3.4.0-0-guacamole-unified-Q-mauronofrio.img. (went fine)
But when I look for the zip file (or any system files) it does not show up , even in TWRP file manager.
Redid data wipe and it tells me "Failed to mount /system_root and /vendor
I am 99% sure that its just because these will not mount:
Does anyone have any idea what I can do to get these mounted to start a regular TWRP flash ?

Well I tried adjusting data format and ended up losing the Stock Rom.
And the stuff will still not mount.
UPDATE, rewiped data and got stock rom to load.
Now Data will load but vendor will not.
UPDATE : data and vendor will mount after data wipe. But still cannot see anything that is placed on device.
Such as the zip files I need to install.
UPDATE: now I sideloaded TWRP onto new phone, but now cannot get it to reboot into Rom.
Its odd after plugging it in , it went to a stock recovery even when TWRP was installed.
Found the issues, finally had to run MSM download tool and fix everything from there and start from scratch.
Ended up installing TWRP from fastboot flash recovery image.
Now to get root going on it and magisk.

What device do you have?
You're in the 7T forum but saying you used the 7 Pro twrp.
If you're using 7T, the reason why you don't see internal storage is because TWRP cannot decrypt on OOS (this is not because of a mounting error, this is simply due how oneplus has implemented their encryption).
And on 7T you don't need a zip of any sort to install twrp.
Reading the actual twrp thread would be a good start.

Yes, I read though the threads, But got so bombarded with pages of stuff kind of lost track.
This is why I posted . Also it is a combined Christmas gift for my daughter that she cannot know I am working on. So I think I tried to rush it when she was in school.
Found out about the decryption part after I started the process. Then it was too late and ended up having to start over with tools.
It was a newb move to end up this far and try to rush it.
People did help me get back on track and now I am working on figuring out Magisk. (good help on magisk threads).
Thanks for your response.

Magisk IS your root

Oneplus 7T - TWRP no OS installed and unable to install OS

Hi all,
I tried rooting my Oneplus 7T (Android 11) but it failed horribly. I started by unlocking my bootloader, then "fastboot boot twrp.img" and it worked. I was in TWRP when I tried flashing Magisk and TWRP, and somehow my OS is gone.
Now, whenever I reboot, it says "No OS installed" and boots back to TWRP. I tried to sideload a stock ROM but failed as well. I did adb push stock rom and tried to install it but it gave the same error. As of now I am clueless on what to do. I already wiped my system and formatted my phone (I already backup everything).
Error code when trying to sideload ROM (both stock and custom):
Failed to mount '/system_root' (permission denied)
Failed to mount '/vendor' (permission denied)
Devices on super may not mount until rebooting recovery.
To flash additional zips, please reboot recovery to switch to the updated slot.
As you can see, I am an idiot.
Please help.

U must flash twrp and not boot twrp:
fastboot flash recovery twrp.img (rename img file to twrp.img and put in same adb folder)

HOLY COW IT WORKED, I managed to reinstall the OS.
Thank you very much HueyT, you certainly saved my day.
So...if I want to root my Oneplus 7T, I need to flash instead of boot TWRP?

Yes, op7t won't like boot TWRP as it has a dedicated recovery partition (both a and b slots-but when u don't specify TWRP goes into both slots)

Is best TWRP for oos11 as allow data backup in twrp

im having a similar issue as OP... with device super message. I flashed the OOS firmware, then TWRP and then the custom rom whichever that may be.
However i have a feeling i am doing something wrong here. The only rom i can boot into is Syberia Android 12. However, after that i cant enter recovery again, and get stuck on the TWRP splash screen.
is there any reason why i cant boot into any custom android 11 roms?

LG F400S/K Kitkat unable to install TWRP recovery / unable to install Gapps (solved)

Now the phone is unable to boot to system, I have no idea what I could do to fix it as there is no way to use adb or fastboot command…
I remember that the stock rom version is S11a, it have some problems when I tried to root it, and failed to flash recovery even I've got the root permission (response "write error: no space left")
------↑solved by using LG flashtool↑------
Now I am facing the problem that unable to install TWRP recovery using dd, it responds “ write error: No space left on device” I’ve reinstall the LG drivers, reboot the phone, reboot the computer, unroot and root again, but the problem still occurs.
----- update ------
solved by using flashify, and TWRP version 3.3.1 instead of latest 3.6.1, so that it won’t have “secure boot error” warning, and boot to recovery successfully.
But there is a new problem now, when I tried to sideload MindTheGapps after installed LOS 18.1 successfully, it warns me “could not mount /mnt/system! Aborting”. This is the third phone that having this warning for me, and I still couldn’t figure out which step goes wrong.
Nothing goes wrong after flashed to lineage recovery, installed MindTheGapps now.
--update--
I also tried to flash lineage recovery from TWRP on my D855, it also works, I installed MindTheGapps and everything works fine. So this is the problem of TWRP? Or reinstall the recovery is the solution? Maybe I would have a test later.

Nexus 5X (NO RPMB): Cannot install Nethunter due to "Data partition appears to be empty" error, TWRP

Tools:
- nethunter-2023.1-bullhead-oreo-kalifs-full.zip
- twrp-3.2.1-0-fbe-4core-bullhead.img
- SR5-SuperSU-v2.82-SR5-20171001224502.zip
- forceencrypt_disabled_dm-verity_disabled (modified boot.img for my Oreo)
I have issues with my Nexus 5X being unable to mount /system partition due to encrypted data. Following several guides found online, I found a way around it by re-formatting /data to ext2 back to ext4 in TWRP.
This allowed me to successfully flash SuperSU and root my Stock Oreo ROM. The problem comes when I try to install Nethunter via TWRP.
I've tried:
1) Flashing both the Stock and force-encrypt-disabled Modified boot.img (neither of which decrypt the /system files in TWRP)
2) Unlock bootloader --> boot into TWRP --> Install Nethunter via ADB sideload (must use sideload since SD card is not mountable)
- This fails, probably because /system cannot be mounted
3) Unlock bootloader --> boot into TWRP --> Format /data to ext2 and back to ext4 --> Mount /system --> Drop Nethunter into SD Card --> Install via TWRP
- This fails due to "Data partition appears to be empty, run Android setup Wizard before installing Nethunter)
SO based on my findings online I can either decrypt /system or keep /data in-tact, but not both. But both appear to be required for the Nethunter installation? I know this is an old device but I am hoping SOMEONE out there has a potential solution.
Thanks in advance!

Same problem, still no solution found....

Hey buddy, sorry I didn’t update this sooner. But I found a solution after asking on Reddit and finally got it working. Here is what I did:
“
Nehunter needs to be installed through magisk. If you want to install a kernel, the provided packages are in AnyKernel3 format, which need to be flashed through the recovery environment.
Here's what I would do, I would reflash the stock ROM, install TWRP, wipe data, system, cache (-s) and install an AOSP based ROM like Lineage OS.
Then I would root using magisk, flashing the apk file as a zip (Don't forget to rename with a .zip extension)
And I would boot into android, download and install magisk, flash the nethunter zip as a magisk module and wait.
You should be done after this point.”
