Fastboot loop - device won't load recovery - OnePlus 6 Questions & Answers

Hi all,
so after system update of OOS which ended up in a boot loop and losing the TWRP recovery (back to stock)
I was trying to get TWRP (back again) via fastboot I was able once to get TWRP loaded once and was even lucky to able to load the Nandroid backup "successfully".
but unfortunately, after restarting...nothing... always getting back to fastboot main screen with no success of booting normally or into recovery mode.
also, not able to re-flash the twrp.img to reach again for the backup.
is there another way to get back TWRP and load my backup file? by using fastboot commands?

I just had the same issue.
I managed to fix it using a fastboot image https://drive.google.com/open?id=1fqvjJ-lC7w2wtcxYwlbmZ4pRW60psODV
After the flash completed I booted into the OS then rebooted back to fastboot and from there I was able to use fastboot command to boot into TWRP

Had a similar issue after installing a rom a while back. Posted about it here https://forum.xda-developers.com/oneplus-6/help/stuck-fastboot-trying-to-install-omnirom-t3849882
Google the mega unbrick guide on the OnePlus forums. Let me know if this helps at all. Or give the other link posted there a try as well.

Nice, we're from the same city.
anyhow, have you flashed this by doing "fastboot flash XYZ.zip" ? & afterwards flashed the TWRP again?

Np. I cant remember exactly but i think it wiped the phone. You won't be able to restore that backup unless you happen to have copied it externally from your phone before the brick.
Let us know if you manage to get it all fixed and going again. Know its frustrating having your phone bricked. Pretty much brought it back to its factory shipped state from what I remember.

Weird Soft-Brick, Need Help!!!

Hi all,
I started out on TWRP version 2.7.1.0, and I wanted to flash the latest TWRP recovery (2.8.7.0), so I used the app that was linked by the TWRP site (TWRP Manager). So I tried to flash the latest update, and then a message pops up telling me to check if this was the right partition. I was careless and I didn't check it, and went ahead and installed it. It said it failed, but next thing I know, every time I tried to reboot(into the system/OS) I just boot right into TWRP (version 2.8.7.0). Then from TWRP (2.8.7.0) I tried to reboot into recovery, and it rebooted into TWRP, except that it was version 2.7.1.0, where I started.
So, when I hit boot into system, I got TWRP (2.8.7.0), and when I hit boot into recovery, I got TWRP 2.7.1.0. I was completely confused, so I wiped the OS, and then booted into fastboot to fastboot flash TWRP(2.8.7.0) in my recovery (It worked). Right now, I'm soft-bricked so I don't have an OS, but I have TWRP(2.8.7.0) as my recovery. Except now, I still get TWRP when I try to boot into system, and fastboot flashing, adb sideloading, and regular TWRP flashing is not working...
Any help is very appreciated, I need my phone to just be working!!! Except, if anyone can help me update it to 5.1 while they're at it, that would be awesome!

Thanks for the reply!
I have already tried to flash the RUU for 4.4.4 but the recovery flash method gave me an error, and the fastboot flash method gave me
FAILED...(remote: not allowed)
I will try again in the morning and let you know how it goes, but I have a feeling it will end the same way.

The firmware is apart of the RUU, did you use cmd

Then flash RUU? Fastboot flash zip nameofRUU.zip

When you go to flash your custom recovery, use fastboot rather than twrp manager. If you MUST use such a shortcut, I might recommend flashify.

I haven't tested fastboot but it should work. TWRP works 100%
Thank you very much, you are a life saver!!
I was stuck in a TWRP loop.
I tried flashing through TWRP but it didn't work but the fastboot method worked like a charm!
My phone is running again.
Thank you very much.

For some reason on my unlocked nokia 1 it started to ask password after flash and boot and gkeyboard always crashes on boot. So, I thought flashing fresh userdata might help.

I wrote in the instructions...
If you get a password just enter a random one, then it will ask you to wipe the device, click ok and it will reboot to recovery and then wipe userdata and boot fine.
just make sure you flash the recovery.bin and not twrp before you wipe

Same happened to me. I solved it by a hard reset via the stock recovery.
Make sure you flash the recovery.bin like Sooti said.
Wiping through twrp doesn't work.
Nice, working twrp for Nokia 1.
I buyed this phone today. Waiting for customs
A little warning.
It looks like the recovery.bin I took from another nokia 1 device doesn't match the checksum check which causes a failed during ota updates, please only flash this rom if you soft bricked your device.
If anyone can get me TA-1060 stock recovery image that should solve it. for now you can't update the phone until a fix is found
I have Nokia Ta 1066. Will this rom work on mine? Also I read somewhere Ta 1060 is single sim variant. What about the second sim?
Has anyone with TA 1066 tried it?
Thanks. Both methods work fine. Don't ask how I found out.....
Can you share how you managed to backup stock recovery file. Maybe after all the steps above we can flash our own device recovery to make ota work again...

I don't have stock recovery from our device i have from another variant of Nokia 1
Hey guys i have a TA-1056 and after unlocking bootloader and flashing TWRP it booted to recovery and came up encrypted, after looking around the only solution was to format data, afterwards when rebooting it always boots to recovery, i tried flashing this zip and i get the same issue and i can't find the stock ROM for the 1056 anywhere online, can anyone help me out? i really appreciate it

Does Nokia 1 support DT2W?
Sir, is that possible to get a stock rom of TA 1056 ?
I have searched everywhere but whole thing available over net just left my phone bricked. All i need is a working rom source. Even if that’s a custom rom too to flash via sp flash tool. Thanks in advance
Can any please repost the firmware , the link isn't working

Magisk uninstall, boots twrp won't boot back into phone OS

I was downloading a OTA update the other day & in preparation I thought I would go ahead & uninstall Magisk. Magisk asked me if I wanted to restore images or uninstall I just uninstalled, not ever having made a image before I didn't know what it was talking about.
The phone rebooted once then booted again into TWRP, I can't get back into my phones OS.
Later I couldn't get back into TWRP so I had to boot using the fastboot commands in Windows. I was able to see & "Backup" the contents of my phone to an external drive.
Now how do I get back into my phone like normal?
Do I need to flash an image or I've seen other threads they wipe the data & there phone boots?
Please advise.
Thank you

First of all, no need to uninstall Magisk - unnecessary and waste of time.
Once in TWRP (fastboot boot twrp.img, or via your phone if you still can) - flash OOS OTA update (as that was what you were trying to do).
Then flash TWRP, reboot TWRP. Now you can flash Magisk again (so you get root, since you removed it for some reason).
Everything should be fine.

Unfortunately now I can't get the "fastboot boot twrp.img" to boot into twrp? FAILED authentication.
Now what?
Fastboot devices work & the reboot function works, just can't boot twrp.img. I've seen somewhere I can maybe force boot the device idk if it will work. damn

Sorry to hear. You are going to have to provide logs of what commands you are typing into terminal, and what is the output.
So are you in TWRP or not. I literally have no idea what is going on with your device or what you are doing.
Next time, maybe check guides in this forum of how to do what you are doing.
Randomly uninstalling/installing/flashing/issuing commands via terminal/random backup and restores/etc.... does not sit well with android devices.
I'll try another pc tonight.
If you can get back to twrp you need to flash magik to boot normally
Still can't back into twrp. Failedremote: failed to load/authenicate boot image: Load error.)
Tried a different computer. Tried deleting my fastboot files on PC then copying them from a backup thinking I modified the twrp image wrong thinking this unmotified version would work, still nothing.
Can I get some advice links to guides. Thank you.

ARE YOU SURE you are typing 'fastboot boot twrp.img' - BOOT, not FLASH!!!???
I'm now able to boot into twrp. Had to use fastboot --set-active=a. Worked great. Left it like that at home. I'm at work now.
What next?

I would start by reading forum page 1 information about what you are trying to do.
I already explained to you the order to flash to make things work.
If that is not enough, once again, go learn what you are trying to do (via the forum thread).
You will probably save yourself these types of situations in the future if you understand what you are doing.
Good luck.
Everything is FULLY Operational Thank You. What a experience but Ive learned.

flashed TWRP over boot slot B

I ended up flashing TWRP over my boot slot (B) and now I just boot into TWRP. I have already installed TWRP on boot slot (a). I can't remember which version of oxygenOS I have installed and couldn't find a way to confirm. How can I fix this? Also want to update to latest version of oxygenOS and android. No data on phone yet. phone still connects to computer, adb sideloader and fastboot commands still work work. Thanks
Are you saying you did fastboot flash boot of the TWRP img? You should be doing fastboot boot TWRP img, then flash the TWRP installer zip.
You can get the OS back up and running by flashing the correct boot.img via fastboot. Or use one of the fastboot stock ROMs.

But to recover his phone, the OP will need the original boot.img from his OS version.
OP has already messed up the boot partition.
That has to be fixed first.

Glad you got it recovered.
There is an application called "Partitions Backup".
It allows you to back up all the phone partitions. The one you really want to backup from now on is the boot_a and boot_b.
Since you are rooted when you do an upgrade, grab the boot_a and boot_b before installing Magisk after the install.
This allows you to go back to stock. After you back them up, copy them to a computer.
hey guys. Not able to flash oos through twrp.

Doesn't TWRP back up everything including boot partitions?
Is there nothing that will take the entire internal storage and just make a 'bare metal' image of it for restoring.. the whole entire thing, byte for byte? If not, why doesn't this exist? It just seems so logical to me and would be so incredibly useful. Phone borked? No problem. Just re-image it form the archive you made. To me, that is what TWRP is all about, at least conceptually if not technically.

[Help Needed] Semi Bricked - Remove substratum overlay or somehow backup my data

Hey Guys,
So my idiot brain decided to mess around with substatum themes after I updated and rerooted my OP7P. I rooted with magisk but forgot to put TWRP recovery on.
Anyways, got the phone semi bricked when applying one of the overlays. The phone boots and I can see my lock screen wallpaper but the screen is just flashing on/off.
I cant use the fingerprint or pin to get it. Is there a way for me to backup my pictures and data or somehow remove substratum?
Biggest problem is that for whatever reason, the update revoked my ADB authorization so it looks like I cant do anything with ADB.
If someone has any way to salvage my situation, please reply. Factory reset is my last resort due to no backup.
Thank You
Try booting into TWRP and using ADB there.
Well boot to fastboot. Flash twrp there and then reboot to twrp.
Flash rescue zip and you should be good to go

Problem is, I dont have TWRP recovery flashed, looks like it reverted to stock recovery after I updated. I rooted with Magisk which does not put TWRP back. I forgot to flash it after.
I also probably wont be able to do anything in fastboot either because the update removed the ADB Authorization and I am unable to accept it since my screen doesnt respond to anything, I will attempt this route though.
Edit: No go. ADB vendor key not set and I dont think I will be able to accept it on my device due to unresponsive screen

Fastboot doesn't need adb.
Switch off the phone, reboot to fastboot.
Then type fastboot boot (filelocation of twrp.img)
Then your phone will boot to twrp.
Flash rescue.zip.
If it is still a no go. Then use msm tool

Rebooted to fastboot, entered the PIN but Fastboot is a no go. Just keeps saying <waiting for any device> and nothing happens. Would that be because the authorization keys were not accepted after the update?
I am downloading the MSM Tool and will try that if I cant get it to work with fastboot. Will update if it works.
Thanks for suggestions
Ended up using the MSM tool. Did not know it wipes data and also put me back to Android 9.
Oh well, lesson learned. Gotta make monthly backups, make sure twrp is installed and working before messing around with substatrum.
Thanks for the help.
