Lost recovery, cant boot, only fastboot - OnePlus 2 Q&A, Help & Troubleshooting

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

XT905 - flashing recovery overwrites system

Hey guys,
I have an stock, unlocked and rooted xt905 lying here with stock recovery right now.
For several times now I tried to flash either cwm or twrp but had no luck.
Thats what I did:
- complete backup
- unlock bootloader
- restore backup
- fastboot flash boot twrp.img
- fastboot reboot
Flashing twrp doesnt throw up any error but as soon as I say reboot, the phone reboots into twrp instead of booting the system.
If I try to reboot to system within twrp, it reboots to twrp again. Booting to recovery from twrp brings me to stock recovery.
Its the same thing with cwm and I dont have any clue why, as other users are saying that twrp is working fine.
Till now I tried several different versions of fastboot, twrp and cwm and none of them worked.
Any ideas?
You're using the wrong fastboot command.
By typing "fastboot flash boot twrp.img" you are flashing TWRP in place of the boot.img. You need to type "fastboot flash recovery TWRP.img."

Embarrassing! I flashed about a dozen phones before and never had any problems whatsoever and now this.....
Thanks anyway! I am glad that I didnt brick the phone with flashing the wrong partition.

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
Sent from my Redmi 3S using Tapatalk
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.

re-installing stock recovery on Nexus 6P

I installed TWRP custom recovery on my Nexus 6P. I was able to boot into it ONCE. When i next tried to enter Recovery, i get a screen showing the Android Robot and the following statement: NO COMMAND
I tried to re-install TWRP using adb twice, but the result is the same.
How can i either fix TWRP, or re-install the stock recovery
I am basically a beginner here, so any help would be appreciated
If you installed the stock system image and then booted into it, it likely automatically reinstalled stock recovery also. I don't know why it does that, but it does. This is why I usually just reinstall TWRP again after each monthly update is completed.
You should use fastboot to install the images, not adb. The command should look like:
fastboot flash recovery twrp.img
I think i just worded it wrong - I used the above command (fastboot flash recovery twrp.img) to install twrp, and then, when i couldn't get back into recovery (Power - Volume Up combo just lest to screen that stated "No Command".), i used the fastboot flash recovery twrp.imp twice to try to re-install TWRP, but it didn't work
I also downloaded the latest stock Oreo ROM, copied the recovery.img file, and used fastboot.flash.recovery.img to try to re-install the stock recovery, but that didn't work either
The once time that TWRP work, it asked it I wanted to use TWRP is read only, to twice i selected NO (don't know if this matters)
Any other suggestions to fix TWPR, or re-install the stock recovery image???
When you say it didn't work, can you expand on that? Was there an error or anything?

If you want TWRP to stick, you need to flash either SuperSU or magisk. The Android with the exclamation mark is what stock recovery looks like.
Once you have TWRP installed and wish to keep it, you don't need to flash stock recovery in the monthly update. Just boot into TWRP after flashing update and root again.

When the phone is turned on, it never progresses beyond the first screen. No error codes, it just does not proceed to boot up.
I had to buy a new phone (need it for business, but i given up on trying to install Resurrection Remix on the Nexus 6P, which was the reason I was trying to install TWPR and SuperSU. So far, I have only accomplished turning the phone into a brick door stop!!!

Use Magisk it's the better solution for root. Never had boot up issues with it just stock you have to boot once through before flashing. Custom ROMs you can flash right away.

Unable to flash TWRP on Moto e3 power with latest software update

I'm trying to flash TWRP (twrp-3.2.1-0-taido.img) on my Moto E3 Power. I had successfully rooted this phone once, and that's why the phone is unlocked. So when I try to flash custom recovery using the command "sudo fastboot flash recovery twrp-3.2.1-0-taido.img", it says it completed successfully, but instead of booting into twrp, my phone is starting up completely. When I tried booting up custom recovery using "sudo fastboot boot twrp-3.2.1-0-taido.img", the same thing happened again.
The software on my phone is "23.0.XT1706_S151_180706_ROW". So far I've been unable to flash twrp on this phone, but I got it to work an year ago. Please, can anyone help me what's going wrong here? I'm following the tips on xda-forums using which other users were able to flash the same recovery on their phones.
you can try this

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?

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.
