So i was just following the instructions from this page https://wiki.lineageos.org/devices/flox/install, was able to unlock the bootloader of my nexus 7 device. Now at this point i didnt know my device codename, i thought it was flox but i just noticed on the bootloader page it says deb. [Im a noob..guilty]
Now the 2nd step was no biggie either, i was able to flash twrp recovery, but somehow it was not working as i was keep getting error 1 and vendor invalid argument when i tried to flash the lineage 18.1 zip.
The recovery img i tried were
lineage-18.1-20211018-recovery-flox.img
twrp-3.4.0-0-deb.img
twrp-3.5.0_9-0-flox.img
twrp-3.5.2_9-0-flo.img
twrp-3.5.2_9-0-flo_followmsi.img
Now after flashing twrp recoveries i was getting the problem of not able to flash the LOS 18.1 rom file, plus if i would format the device and then try to reboot the device back to recovery i would get an error with android logo collapsed [check the image]
what am i doing wrong? plz help.
I sense its repartitioning process? also i am not sure if i did an EFS Persists back up.
so if someone can give a walkthrough. would be very greatful _/\_
thanks again
Was your device rooted? Start it in to recovery mode, go to "Mount". And see if you could chose system directory. If not, that means TWRP can't access system directory and will not be able to flash any custom ROM until you sort root permissions.
Edit: Sorry just now noticed that you can't get in to recovery mode anymore. Connect your device to computer and use Nexus Root Toolkit to flash TWRP recovery.

Guys... when i tried to flash oos 3.0 on my op2 through twrp, i first wiped the data to install new rom, then install oos 3.0, it failed. I then flashed the recovery i downloaded from the thread, then restart the recovery
I cant boot into the recovery.
System can't boot
Is it called "brick"?
So i tried to flash stock recovery in pc by command, but it says "remote: device is locked. cannot flash images". any solution to this problem?
I can boot into fastboot mode
You need to run the phone in Qualcomm mode on a PC and run the recovery tool to fix you bootloader.
I did the same and it was a royal ball ache trying to find out how to fix it
Don't do what rosswaa said
Why not?
What you should do is boot your phone into fastboot mode, connect it to your pc. Flash this modified TWRP recovery img to your phone https://www.androidfilehost.com/?fid=24459283995297945. After that you have to flash this modified SuperSU (through the new recovery) https://www.androidfilehost.com/?fid=24459283995297946.
The normal recovery doesn't work in OOS 3.0 (just like in HOS) and it's the SuperSU that gives you the soft brick. A dirty flash of the modified SuperSU should fix it.
I also had your problem and I did what rosswaa said which shouldn't be necessary (I lost all my data and backups).
I didn't lose anything, but I tried doing what you said and my bootloader was screwed so wouldn't take a flashed recovery or anything (yes the modified one)
Wish I hadnt been so excited and just flashed but all sorted now
Hmm okay, if it doesn't work with flashing the new recovery img then do what rosswaa said and after that follow this post https://forums.oneplus.net/threads/installation-instructions-faqs-oxygenos-3-0-0.439108/
Obviously try what green says first, if it works then happy days
first i am really glad that someone give some advices on me. But since i am a noob, how can i flash twrp in fastboot mode? using command? "fastboot flash recovery xxx.img"? thx

I tried to unlock my phone (A2017G) and flash lineage OS today following Controllerboys guide, but must have done something wrong, I managed to unlock it and flash the bootstack, but I hit an error when trying to flash LOS and so decided to reboot the system and try again, however when rebooting the system I got the error "Your device software can't be checked for corruption, Please lock the bootloader". And I cant seem to access TWRP anymore just the stock recovery.
Is there a way that I can just flash stock OS and be able to use my phone?

That's not an error message, it's the unlocked bootlaoder screen. get used to it, you're gonna see it every time you reboot
You probably didn't flash the Universal Bootloader. You didn't even read. You should install TWRP again with axon7tool, then get there and flash the Universal Bootloader, then the A2017G modem, the the ROM. If that doesn't work just download MiFlash and the latest G package and flash it
I may or may not have TWRP installed. Because, it's stuck on the bootloader when it switches on. I can only get into fastboot. Not more than that. No more Recovery mode. All the tutorials I see online for flashing with QFIL is only for A6000 (not Plus). I have A6000 Plus. What do I have to get it back on the track?
I've searched on other topics about this. But, they're all for A6000. I don't wanna brick more. So, any help would be appreciated.
If u can enter into fast boot then flash the twrp
U can watch at YouTube about flashing twrp
If u cant flash the twrp or get into the twrp !!!
Then flash the stock ROM ...!!!

Most tutorials for A6000 work for the "Plus" variant and vice versa, so it might be worth checking them out.
Also if you had usb debugging on and can send commands to your device from ADB, you can boot into recovery by this command:
fastboot boot recovery xxxx.img
Where "xxxx" is the name of the recovery file which must be in the adb folder.
Feel free to ask if any query

I was like why didn't I try this before.
You know what happened? The boot process on "Command Prompt" screen went fine. I heard the unplugging the device and replugging the device sound very well. But during all these process it stays on Fastboot mode forever.
I have the latest TWRP loaded for temporary boot process. (3.2.1)
Besides from that
I was finally able to flash with QFIL tool. But still stucks at Lenovo POWERED BY android logo. QCom Downloader didn't work. But QFIL tool did work. I was able to finally come over the "sahara error" by quickly clicking "Download" button after connecting the cable. Then it flashed all the files. Then it finished downloading. But then if I try to switch it on, it wouldn't boot. Still stucks at the screen that I mentioned earlier.

Sorry!
I tried it with Stock Recovery of A6000 (not plus). It booted into recovery.
Now, I can boot into TWRP. Looks like all the partitions are gone. How do I recover that?

Sorry for previous post.
I tried to boot with Stock Recovery. It booted to recovery. But then I tried with TWRP again. It worked.
Looks like all the partitions are gone. How do I retain it?

Haha. I know how to do that. Thing is, I can't boot into System or Recovery normally even if I flash via Fastboot. I can only boot to recovery by "fastboot boot recovery.img" Then in TWRP there, I can't flash any roms as it shows Failed to mount /system /data /cache all the time. Tried fixing with "repair file system" option in TWRP. Still doesn't work.

Use the TWRP provided in the RR thread.
Wipe everything except MicroSD, if it shows any error while wiping, repair the partition in which the error arises and then wipe. After that flash the HEX firmware in RR thread and then flash ROM.
(Side Question : how did you land up in this situation?)

The TWRP I mentioned 3.1.0 was obtained from RR forum only where dev mentions "F2FS" support. It does show the same error that I mentioned earlier. I did repair, resize, format, change file system. What ever I do, I always get the mount error on 3 partitions. Can't flash any ROMs either. Shows that error 7 and 6. I even deleted the assert line. It would only land me on error 6. I even googled and tried to get rid of that error. But after the error 6 or 7, it shows the same "mount failed".
Not my device. One of my client's. Received as not working.
Hello everyone
My phone suddenly went into a boot look after multiple process getting stopped.
After that its not booting.
Now it shows the unable to mount E:failed to mount /cache (Invalid argument and i haven't unlocked the boot loader.
please help me with the same.
i have tried wipe cache partition , system reset everything,
If I understand correctly you can't use the official bootloader unlock app because your phone isn't booting android. I'm guessing your recovery is also not working or you would just factory reset the device and boot into android to unlock the bootloader.
I don't know of any unofficial way to unlock the bootloader so if I were you i'd just do it the official way.
1. Download the raw firmware for your device as well as the ASUS Flash Tool.
2. Boot your phone into fastboot and flash it with AFT.
3. Boot your phone into android if you can. If not, at lease your recovery should be working now. Download the latest device firmware form the ASUS website and flash it using the recovery menu of your device. (power + vol down)
4. Boot your phone into android install the bootloader apk.
5. Open bootloader unlocker app to unlock the device (you need to be connected to the internet for this bit)
Raw firmware for your device can be difficult to find but this one worked for me https://ainotech.com/how-to-flash-fi...twrp-recovery/
I am looking for the unofficial method because the official method does not work now.

I am successful this way, Peetama flash official beta rom 6.0.1 raw. After successfully booting back to fastboot to flash twrp. Once done, immediately reboot into twrp. Flash the magisk if necessary. But I went straight to the custom rom viper os 3.1.1 and done.
For details You can read the article here TWRP WITHOUT UBL

Attempted to update from the latest stable 10.3.12 to 11 by flashing the full OTA zip in TWRP.
Install failed and phone locked up.
Attempting to boot to recovery or system results in Qualcomm Crashdump Mode.
I can get to Fastboot, but I'm not sure if I should try flashing twrp.img or pull boot.img from the OTA or what.
Anyone have any suggestions?

I did not have time to wait so before bed I just reset everything.
I ended up using the MSM tool located here:
The Complete Guide to Unbrick OnePlus 6/6T from a Hard-Brick using MSMDownload Tool
Unlocked bootloader, installed TWRP & Magisk, installed A11 zip, everything is working again now.
Good luck!

Flash temporary recovery first ( lineage recovery ) then from fastboot.. boot into recovery.
You will see lineage recovery.
Select apply update - > update from adb ....
Then "adb sideload <twrp image>.img...
(probably it ask to verify choose yes)
Go back select advanced restart ( not sure the right word ) -> reboot to recovery.
Then you will have twrp installed.
If you only want to root why not flash magiskpatched image there no need TWRP just to root.

Hm but how would I install lineage recovery? Flashing recovery through fastboot doesn't work on the new devices anymore right?
I also tried booting lineage recovery without flashing but that also didn't work (although it didn't get stuck on crashdump but booted into the regular OS instead).
I did notice that it seems to be related to OOS 11 firmware. On 10 booting into TWRP works just fine and as soon as I upgrade to 11 it stops working (maybe this means it's fixable?). What I used as a workaround for now is to have 10 firmware in one slot, upgrade other slot to 11 and flash TWRP to both slots from the 10 slot. Seems to work so far but is not ideal IMO. I'm not a developer sadly but maybe someone smarter than me will come up with a solution.
What do you mean by "new device"?? New OOS version right??
I use this method all the time with oos 11.x.x.x.x to install TWRP so i can install Custom ROM later.
no need to go to oos 10 you can flash it from newest oos11.
