I think my system portion is corrupt... Any chance of saving it?

I have a 2012 Nexus 7. At the time it had a locked bootloader but it was rooted with cm11 & TWRP on board. I downloaded the Nexus toolkit & tried to upgrade to lollipop when it was officially released. Somewhere along the line, I think the system partition got corrupted. I can manually flash all IMG files except system. I can get into bootloader & recovery. I even tried flashing TWRP again to reflash cm. TWRP took but cm failed to install. Anyone else have this issue? The tablet appears to boot but it just gets stuck at the Google screen with the lock at the bottom. Never goes past that point. Any help to revive this tablet would be much appreciated.

Can you enter recovery or fastboot mode? If so, use either to attempt and repair (format) the system partition, then reflash the ROM of your choice.

In Twrp recovery,
1. go to wipe menu and advanced wipe.
2. select system partition then tap repair.
3.Flash your rom

Ok so that worked to flash cm but will this continue to happen if I try flashing the official lollipop update? I'm trying to return to stock so I can give the tablet to my nephew. I don't want him jumping into recovery or bootloader & wrecking it for good

Need Help; My LG G6 (H870) keeps booting in TWRP and I can't install stock ROM

Hi,
I unlocked the bootloader of my H870, installed TWRP 3.1.1.0 and SUPERSU. Everything was working great untill I decided to restore my system defaults to make a fresh start with my G6. After choosing the option to restore system defaults, my phone rebooted and it booted into TWRP. I rebooted my phone and it kept doing this all the time.
I decided to look for a stock ROM and flash that ROM.
I succesfully flashed the "LG-H87010f-Flashable.COMPLETE.zip" ROM (from autoprime's post) trough TWRP. But this did not work. I even wiped all the data from my phone (even system) and flashed the ROM again; still nothing.
Before having this issue, I had the same Baseband version, Kernel version, Build number. Only the dates and the Software Version are different.
I had the V10b-EUR-XX Software Version installed on my phone. I see this is the 10f version. I guess this should not be a problem right?
After this I took these steps solve this issue:
1. Downloaded new LG Mobile Drivers (LGMobileDriver_WHQL_Ver_4.2.0)
2. Downloaded and installed LGUP. LGUP doesnt recognize my phone as a LG G6 and this method did not work for that reason.
Fastboot mode is working on my phone; I can reboot my phone trough the commandline on my PC and things like that . However, my PC is not recognizing my phone as a LG G6 device in Fastboot mode.
My PC recognices my phone as a H870 when in TWRP. In Fastboot mode it recognices my phone as Android Device.
3. Installed LG Bridge for more drivers; did not work either
4. Downloaded Uppercut, but it doenst work without LGUP.
4. Looked all over the internet to find a Stock ROM in .zip or .img format; found nothing
5. Downloaded WindowsLGFirmwareExtract-1.2.6.1 and tried to extract the H87010d_00_OPEN_EU_OP_0327.kdz file. I extracted it into .bin files, but they were not usable. After that, I combined these .bin files into a system.img file. But that .img file was bigger then 5 GB and for that reason it was not usable to flash trough Fastboot or TWRP.
7. Looked for other methods to obtain a H870 Stock Rom, including another extraction method, but I cant figure out how to do this.
I have spend countless hours on this problem, but I cant find an usable H870 stock rom to flash my phone with.
Is there someone that can help me out with this problem? Im willing to donate some € if someone helps me to get my phone working again.
Really hoping for a kind person to help me out and provide me solution for this issue.
Thanks in advance

Try formating data in TWRP(not factory reset) then flash the 10f complete zip. Trying to perform a factory reset from within Android could have possibly messed up your data (due to TWRP being installed instead of stock recovery) so a full data format is needed.
Lgup most likely doesn't detect the phone because you wiped system. But flashing the complete zip should have restored system.
In the future make backups in TWRP to restore later.. or flash a kdz with lg bridge or lgup without wiping system first.

Thanks for your reply. I have already formatted data in TWRP, but im still having this problem . It seems like something is preventing my device from starting up. I have flashed several ROMS on other devices, but never experienced something like this. Is there something else I can try? Can I flash the stock recovery and flash the stock ROM? I got the feeling TWRP is causing this issue.
If its possible to flash stock recovery, where can I find it?

Flash the complete zip then boot into download mode and flash kdz. Lgup should see the device as a g6 now instead of unknown device. If lgup isn't seeing any device at all (including unknown device) then your setup is off.. missing drivers or something. If that doesn't work.. idk.

Don't factory reset using the in phone option. You can only do this through twrp's option. To fix this you'll need to boot through the hard side, using power and volume down until the lg logo appears then release power for 1 sec and then repress keeping volume down pressed. Confirm yes twice on the white screens to get to twrp. Once in twrp then reset again and reflash the system. Then using twrps img installer flash your twrp img(make sure it is on ext sd) again. Then reboot.

Probably because you already did all the flashing prior to. Glad it worked. This happened when I first got my V20 and was stoned not thinking. I reset using the in phone option and it caused twrp bootloop. I too learned the hard way.

Had the same issue, fixed it, thanks.

My phone kept doing this booting into recovery no mattery what ROM I installed.
I got into twrp by holding volume down and selecting yes on next 2 white screens....but now this message appears all the time.
please can someone help??

Flash a firmware trough LGUp, or flash again the last TWRP available trough fastboot.

Great tip @Swizzle82! It allowed me to restore my LG G6 after bootloop. It had not been detected by PC, and this hardware reset helped!

Hi, all
If I understand, and to sum up :
I rooted my LG-G6 few weeks ago, and intall TWRP. When OTA wants to install official update, the reboot stops in TWRP mod, so ... failed :-/
Is the solution to flash through Uppercut/LGUP with a .kdz file, without risk of brick the phone ?
Thx

OP5 bootloop with every ROM

Hey fellas,
so I rooted my phone and tried to install some Magisk modules, but after rebooting it got stuck in the TWRP bootloop. So I flashed the Nandroid backup and it got stuck in the OOS boot animation. After that I tried reflashing OOS, but it didn't change anything, so I tried Lineage OS and now it won't even get past the Oneplus logo at the beginning and keeps restarting.
Thanks in advance
EDIT: when I flash the stock ROM through TWRP it installs normally, but then when I try to reboot it says there is no OS. So I flashed the stock OS to try adb sideload, but my pc says it cannot read the zip.
I also decrypted my phone through the OP5 Decrypt App, before the bootloop it worked for some time.
Of course I wiped everything before every action.

if you can bootup into recovery, try go into advanced and format data and system.
if you can't your last chance is using adb - flash a default rom.

Is it any different than wiping everything? Because it didn't do anything. I can access both twrp and fastboot so I guess it's not that bad

sounds like you went from unencrypted to an encrypted rom and your data is encrypted, or visa versa.

yep, it's vice versa, I used the OP5 Decrypt App after rooting. Is OP5 encrypted by default?

If you've tried the Android 8.0 Rom, just go to the official OP5 support site and download stock rom, flash it via ADB sideload if you can. (Don't forget to format data etc etc..) and restart from scratch.
Unlock BL if it's relock, then flash TWRP and go for a custom ROM. That's what I did, happened to me 2 days ago.f
EDIT : Oh you just flashed Magisk.. Well, try this anyway.

I tried flashing Lineage, but I can't install Oxygen

Ok, so apparently OOS boots up only after relocking the bootloader. And I had to make adb use more RAM to get sideload to work.

[Help] TWRP can't install stock rom and lost encryption. Phone no OS installed.

I was on beta 3 and decided to flash a new version of OOS. I flashed 9.0.11 -> reflashed TWRP and magisk but when I rebooted, it went straight back to TWRP.
I had to switch to a different slot and the phone booted to OOS beta 3 again. Tried to flash 9.0.11 and reflashed beta 3 again but the same thing happened.
Then i swiped everything except for USB storage and Internal Storage in TWRP and now the phone is without OS.
I rebooted to TWRP and now TWRP lost the encryption and I can't flash anything anymore.
Does anybody know how to recover from this?
I'm using the official TWRP build.

Dont panic just download a fast boot rom for version 9.0.11 and run it from fastboot using terminal. Then you will need to flash Magisk in order to have root access.

How do you do that using the terminal? I tried following this topic https://forum.xda-developers.com/oneplus-6t/how-to/rom-stock-fastboot-roms-oneplus-6t-t3862516 but I got this error

TWRP still can't flash OOS
So I was able to boot the phone up again using MSMdownloadTool but the problem still persist. I was supposed to be at OOS 9.0.11 but upon checking I found out I was still on open beta 3. Tried to flash 9.0.11 via TWRP and the same thing happened. I was on slot B so when I flashed OOS and rebooted, it rebooted to slot A and brought me straight back to TWRP. It won't boot again until I switch back to slot B to boot and slot B was still on open beta 3. Any thoughts?

Flash a patched
Code:

when I got the problem, I did that and it worked, booted me to system but if that doesn't work then you have to flash Magisk.

This phone has A/B partitions and is able to store a backup version of the OS so if a new installed version doesn't boot it will revert back to the old one.
When Flashing, you need to flash "BOTH" slots.
If you used the MSM tool to boot, you just booted and not flashed.
The MSM tool will flash your phone, restore the stock recovery and relic the bootloader. It will look like it came out of the box.
I don't know how to get you from wrapped around the axle except to tell you to run the MSM tool and let it wipe the phone and get you back to stock. You can then unlock the BL again and install TWRP, etc if you like.

You are booting into TWRP because you did not format your data partition. When flashing OOS, you need to not only wipe data, but also under the Wipe menu, select format data. It should prompt you to type "yes".

Odd. If I had to guess anything, it would be that not all the partitions were flashed when going from Nougat to Oreo.
I once flash a Nougat ROM from an Oreo ROM and I had the same encryption issue and lost everything.
That was the last time I would trust myself again and not do a backup.

Flash stock recovery from KDZ through patched LGUP & do a factory reset .
After stock recovery completes the wipe do a battery pull, flash TWRP via fastboot, format data, flash Kernel & Magisk & you should be back on track...

I tried that as well. With stock recovery is says data is corrupted and doesn't do anything. I think it might be a problem with patched lg up because when i use normal lg up to flash oreo it works. But I cant root then.

I would try changing to 3.2.3-4 TWRP and then trying the procedure again. It seems that the 3.3.0 TWRP does not decrypt properly sometimes.

In the same boat as OP

Hi
Looking for a way to keep TWRP and root ... any help appreciated
I've got a US996 with the same issue as the op. I have the latest TWRP 3.3.1-0. The phone was working fine until I upgraded twrp but I might have done a mistake resetting phone outside of twrp.
I can still get back into twrp but I haven't been able to install zip files without getting that decryption unsuccessful message when booting to system.
When getting back into TWRP using hardware buttons sometimes there is a prompt asking "keep system read only?" which I never chose and swipe to allow modification. I think this happens after
I pull the battery after getting the decryption unsuccessful message. There is a reset system that I could chose under the decryption unsuccessful message but I'm assuming that will make me lose twrp
...but if my phone is a us996 and is still
unlocked, would it matter if I did select it? Wouldn't I be able to reinstall twrp using adb again on a computer after Oreo is reinstalled?
To do Prowler_gr's suggestion which guide do I follow (sounds like I should do the second option)
"Flash stock recovery from KDZ through patched LGUP & do a factory reset .
After stock recovery completes the wipe do a battery pull, flash TWRP via fastboot, format data, flash Kernel & Magisk & you should be back on track... "

Don't blame me if this goes wrong but I'm pretty much 100% certain that you mush press the rest button. This has happened to me a few times I'm sure. You won't loose twrp. Whatever resetting goes on in the background I don't think it's an actual Factory Reset.
Edit: Just to be clear you taking about a white screen with I think in dark blue or black text ENCRYPTION UNSUCCESSFUL and something like "reset phone" option directly under it, on the upper half of the screen?

Hi ezzony
Yes you are thinking of the right decryption unsuccessful page. I get it when booting to system
after installing Oreo and magisk 19 and having wiped everything (format data too). I will get the exact wording of it tonight
Thanks!
