Lost recovery, cant boot, only fastboot

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

Boot into TWRP. Goto Advanced --> Disable DM-Verify. Reboot device. Done.

now i installed the supersu but when i reboot the phone it always boots to TWRP i think because i flashed
fastboot flash boot twrp.img (yes i am a idiot)
if i want to boot the system what should i do?

As far as I read this thread you forgot to turn off the DM-Verify option in TWRP after install and rebooted immediately.....
Hate to break it to you but your currently installed OS is now pretty much dead now. Had the same issue when I first tried it.
You need to install a clean MIUI ROM first via fastboot and MIFlash-Tool. Then proceed to install TWRP again. When TWRP is booted the first time it will ask your permission to Modify the System. Swipe to confirm that (needed for most operations TWRP is able to do).
After you allow the system modify part, you are in TWRPs main menu. Tap on "Advanced", then tap on "Disable DM-Verify". Once again swipe to confirm.
After that, you should be able to have TWRP on your device and should be able to boot normally to MIUI... or you go straight ahead and flash a new Custom Rom.

thank you.
So i will need to download a new rom (any suggestion on which one is good? i did install twrp because my vendor rom didn't work with local 3g and LTE) and install it with the miui flash tool. Than repeat the twrp installation but disable dm-verify first, (than reinstall super su?),and at the end reboot.
No need to clear anything?

i flashed the global stable rom from the xiaomi flash tool it say successful and took just a second but i am stuck still on mi logo....

Is your phone unlocked?
In fastboot fastboot oem device-info

i unlocked it just one day before with permission message from xiaomi.

Next time used cofface twrp for redmi 3S: http://en.miui.com/thread-244098-1-1.html

Ez. Go to fastboot mode, flash again the whole ROM and flash your TWRP again. Don't forget to disable DM-verify. It stuck at logo not because of you forgot to root your device, is because of you forget to disable DM-verify.

Can't install TWRP, no bootable A/B slot

Dear all,
after trying to install TWRP (from the official homepage), the bootloader logs show the following message on my phone (moto g6 plus):
AP fastboot Flash Mode (Secure)
No bootable A/B slot
Failed to boot Linux, falling back to fastboot
Fastboot reason: Fall-trough from recovery boot mode
Any recommendations, what I can do/try now?

With volumen keys search for a green letters "Start" and flash stock rom or flash boot.img from stock.
Kepp in mind that Official TWRP can't be installed only BOOTED so don't try it again there's a flashable TWRP installer here:
https://forum.xda-developers.com/g6-plus/how-to/twrp-installer-zip-evert-t3875657
KEEP IN MIND THAT WE CAN FLASH THE INSTALLER BUT ISN'T RECOMMENDED!

DON'T DO WHAT YOU WANT when a script is given from the creator IT IS NO A PROBLEM.
I know muy words are so really bad but is the truth. Reflash all the stock system and after it BOOT twrp is you need but dont flash cause we don't have a recovery partition, so, we can't use twrp like un older moto phones

Failed Update from 10.3.12 to 11 - Assistance Appreciated

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?

An attempt to flash TWRP and reflashing should go.

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.
---------------------------------------------------------------------------------------------------------------
First boot into fastboot mode.
to install lineage recovery
fastboot flash boot <lineage recovery image>.img
download from here https://download.lineageos.org/fajita
menualy select and boot to recovery. It will boot to lineage recovery.

lmao it appear in two posts. deleted 1.

NEED HELP

I INSTALLED NEW VERSION TWRP RECOVERY IN ASUS ZENFONE MAX M1 BUT PHONE BOOTED STOCK RECOVERY AND MY PHONE BOOTING LONG TIME 15-20 MINTS ‍‍‍

Did you unlock your bootloader first, if not, the recovery you wiped will restore itself, but if it cant...?
May also be caused by a/b partitioning? booting wrong boot slot..?

Yes I unlocked Bootloader this phone first time then flashed TWRP RECOVERY for official letest version from BUGJAEGER APP SUCCESSFUL but my phone BOOTING stock recovery AND system BOOTING 15-20 minutes

Because even though you unlocked bootloader, it is still stock bootloader, root it.

I try to many time to root but not working magisk,rootking & iroot but not working . Any suggestions ??

Get stock firmware for your fone.
It should be a zip.
extract that, go into the extracted folder, find boot.img
Place this boot.img in your adb folder
adb push boot.img /storage/emulated/0/Download (note: your dir may be slightly different, notice magisk looks in default folder 'Downloads'? Note the 's' ).
Then install magisk CANARY version, and point it to the boot.img now on your fone.
If your fone is online, it will flash your boot for you at this point. If it can ?
Make a backup of what magisk leaves in your fone. If it does not, backup your bootloader after it's complete, saves the hassle of being online everytime you need to root again

I flashed magisk boot.img now my phone stuck on fastboot mode how to fix ???‍

Did you flash it manually, via fastboot flash boot magisk_boot.img
or let magisk flash it while online? How did you go about it?
And what size is your bootloader? Some know I'm looking for 32mb bootloaders just now, not the 64mb ones
Also, do you know if your a/b partition?
What OS?
9,10,11,12?

I download boot.img on XDA then flashed magisk after reboot (magisk_patched-23000_YdcW1.img ) this file flashed fastboot mode on.
I don't know Bootloader size
Android 8
Check photo . This is right way ??
