One plus 6 completly bricked - OnePlus 6 Questions & Answers

Hi everyone,
I'm quite new to unlocking and rooted phone, but I've read many many post on this forum but nothing worked....
Here what's happening;
Few days ago I wanted to Recover from TWRP a backup that I've made. I launch the recovery from TWRP (important details, it was a backup that I made from slot B in twrp....) in slot A.
So yes I indeed restore a slot B recovery into the slot A in TWRP.....
And I tried to reboot after that..... and the problems begins !!
I just have a blackscreen with a blue light, nothing happened..... Same thing If i try to boot into recovery mode.....
Since I tried many many things but nothing worked...... I can't boot into TWRP from fastboot.
When I'm trying that:
Code:
fastboot boot twrp-3.2.2-0-enchilada.img
The phone just reboot and got stucked on the screen with one plus logo and the text "fastboot mode" below the logo.....
I read all these post below and everything I tried (erase all data, change the active slot on fastboot mode......)didn't work:
https://forum.xda-developers.com/oneplus-6/help/oneplus-6-os-twrp-stuck-fastboot-screen-t3870989
https://forum.xda-developers.com/oneplus-6/help/stuck-fastboot-rooted-help-please-t3851802
This one I didn't really understand exactly what needed to be done but I guess I need to boot into a custom recovery as well:
https://forum.xda-developers.com/oneplus-6/how-to/guide-mega-unbrick-guide-hard-bricked-t3796051
Even tried that but it didn't unbrick the phone:
https://forum.xda-developers.com/oneplus-6/how-to/rom-stock-fastboot-roms-oneplus-6-t3796665
I tried to boot into another recovery, but same thing not working/booting;
Code:
fastboot boot blu_spark_r65-oos-pie_op6_9a5f932e4.zip
So I'm desesperate and really really need help !!:crying::crying:
Does anyone can help me step by step or has a solution please?
I can access to fastboot mode that is the only think I can do and the bootloader is unlocked.

Go and see there :
https://forum.xda-developers.com/oneplus-6/how-to/tool-msmdownloadtool-v4-0-international-t3903272
You'll get your phone like it comes out of the box.

yep, do this:
https://forum.xda-developers.com/oneplus-6/how-to/tool-msmdownloadtool-v4-0-international-t3903272
I had the same problem with my OP3. i cant get past the fastboot screen. after i tried the tool everything was back to normal. but i had to oem lock after it to boot up.

Also use the official twrp for a fully functional backup and restore

Thank you all for your reply !
I've tried to follow the process from the link but the MSMTool is not finding my OP6 and I've uninstall in the Device Manager as indicated:
HTML:
plug in the phone to the computer, go in device manager and under port (COM) disinstall qualcomm one (oneplus 6) and then unplug
But When I go into safe mode and re-plug, I can't do this part because I don't have this information....
HTML:
Now you have to see US8_BULK as new device connected and you can also see in device manager; if you can't notice it, repeat the process until you see it (power on, power off, hold...) there is a full youtube guide for op5 and it's the same process
I tried on 2 different PC (Windows 10 and 7) but nothing worked so I can't used the MSMTool

You have to use it in safe mode to install the unsigned drivers. It only works when you see the device as something like 9800 in your device manager.
Dont worry if it fails a few times. I had to do this 8 times on my OP3 till it was successful.
You can also use this guide:
https://forum.xda-developers.com/oneplus-3/how-to/guide-mega-unbrick-guide-hard-bricked-t3405700
The steps are the same

[Resolved] HT16 Stuck In Bootloop

Hi! I'm kind of new to this so please forgive me (done once before with a few problems).
Basically, I was looking to root my new HomTom HT16 with SuperSU by downloading a custom recovery (TWRP). I rebooted into bootloader with USB Debugging enabled and OEM Unlocking enabled too.
I selected Fastboot mode from the menu in the bootloader and plugged my phone into my computer. I had no problems recognising the device. I followed the bootloader unlocking steps with:
{fastboot oem unlock}
The instructions that I was originally followed told me that I had to use the Fastboot command (with the recovery.img being TWRP):
{fastboot flash recovery recovery.img}
I was told nowhere that I had to clear any cache partitions (still not sure if I had too). Everything I did seemed successful until I was told to take the battery out, put it back in and turn the device on. It brought up the "HOMTOM" text for the boot screen but instead of booting, it repeatedly turned off and on. Because none of this actually worked, it didn't actually flash the recovery, and so I couldn't boot to it. It just got stuck in a boot loop.
I searched up how to fix a bootloop and I could find anywhere a solid solution unless I just wasn't looking properly. I have all the factory ROM files, I just don't know how to use them to replace anything that could be corrupted. I flashed back the original recovery.img but it still will not turn on, it just says on the "HOMTOM" text screen for a very long time. The recovery also doesn't work, it's just an image of broken android with its internals showing.
Does anyone know what to do now?

Do you say you have the original files if yes, then if your device is a Mediatek device use SP Flash Tool to flash the rom. If you still need help contact me here or on [email protected]

Cannot boot my OnePlus 6! Please help!

Hey guys!
So, my OnePlus 6 won't boot! My problems started when I tried to flash MIUI 10 port. Idk what I did, and appeared to me "your device is corrupted". But ok, i could boot normally.
Then, I tried to downgrade, as there is a tutorial here in XDA, I was in OOS 9.0.4, then rollback to 5.1.1 (i guess) with appropriate file. Installed it, and rebooted it. But it was taking longer than I expected, and I rebooted it into fastboot mode to flash stock image into fastboot (as there is a tutorial here too). And after this, the ROM install, in my computer everything seems to be ok, but as soon as the CMD reboots it, the message "unlocked bootloader" appears, and then, goes black. Only that. Oh, the notification LED also lights up white!
I connected it into my pc, and i can hear the sound that "something is plugged in", but I can do nothing. I can access fastboot mode normally though.
Tried the tutorial in msm download tool, but had some problems... I mean, it doesn't recognize my phone, but if I put in PowerShell, and type "fastboot devices", it recognizes it.
Could you please help me?

Did you installed fastboot adb drivers and oneplus drivers?
Or maybe try to wipe everything in fastboot and then install fastboot stock rom...
Follow the guide of msmdownloadtool, it's the best way to recover your phone, it's a pain the part of install the qualcom driver, but persist
only way to recover stock receovery and back to normal is to install msmdownload tool you can see the videos available on you tube

I tried this method before, and find this method to be simpler. If the PC is not recognizing your phone, try powering completely off, then press Volume Up button for at least 5 secs before plugging into the PC and going into the MSM flashing tool. You don't need OnePlus drivers preinstalled for the PC to recognize your phone in this state. From there, just click "Start" on the MSM flashing tool, and wait for your phone to boot back to life. Take note any data inside will be completely wiped clean, like it was flashed from the factory. This YouTube guide here will help you better understand this.

If you are able to use fastboot, can you download the latest compatibly TWRP for your device from the official website (twrp.me) get the IMG & ZIP files ( you can use just the image for both, but to keep it simple get both).
Boot into TWRP using the image you just downloaded by running
Code:
fastboot boot <img file name>
Your device should reboot into TWRP.
With your device in TWRPyou should be able to push the file to the phone using ADB push.
Code:
adb push <twrp zip file.zip> /sdcard/
From within TWRP install this zip image. * Now you should have a permanent TWRP recovery, until another OS/recovery flash.
To get the OS on the phone now -
Download the most recent official release for Stable OOS.
Code:
adb push <full os image.zip> /sdcard/
*That should put the file in the root of the SD card folder.
Again use TWRP to install this zip file on to the phone. * This will wipe the TWRP image we had just installed.
To get TWRP again, just flash TWRP after the OS image flash.
I would also suggest, reboot back into TWRP and install the OS & TWRP again as above.
Flashing the OS twice will flash the same version on both Partition A & B. This is essential.
If you find these steps confusing then the simple solution would be to use the MSM downlad tool it does everything for you with a few clicks.

[GUIDE] Recover your Bricked phone. SIM error. Bootloop Fix

Hello there,
this is my first thread so maybe I can make some mistakes.
I tried to install Lineage in my Mi A1, with their wiki guide. Then the device bootlooped, I tried with a lot of guides, tutorials, I used Cosmic Dan's TWRP for formating partitions, installed vendor images...
But the phone was ****ed up... I tried to install a fastboot ROM but the phone didnt have signal, or it was stucked in the SIM password...
If someone is facing some similar problem, I would like to help you. Like I said before, I tried with a lot of methods, a lot of different recoveries, I tried https://forum.xda-developers.com/mi-a1/development/twrp-stock-8-1-0-t3856328 this one too, all tipes of fastboot or TWRP stock ROMs... but no clue of how solving it.
So THIS is the only way(for me at least) for solving it. It is in Indian, but you can follow his steps if you flashed any ROM before, is quite easy.
1. - You need your phone to be unlocked, if you dont have it, just use the command "fastboot oem unlock" while you are in fastboot mode. There are plenty of guides for this.
2- You have to run MiFlash. If you dont have it HERE you have the version that I used.
3. Download and extract THIS Rom. Then copy the link to MiFlash like he does in the video, or browse for the folder.
4. Plug your phone in Fastboot mode, and click reflresh, till you see a device in the MiFlash tool. Check that you have the "clean all" option in the bottom of the app. DONT CHOOSE THE LOCK ONE.
After this your phone still wont work, dont worry, just press Vol Down+Power again till' the phone enters fastboot again.
5. Download TWRP and boot the phone with the recovery using the command "bootloader boot twrp-3.2.3-1-tissot.img.html" in the adb folder(same steps that the other TWRP versions with temporal boot)
6. Download this Backup and copy the folder inside the 7z to the device(not to the sd) and replace the TWRP folder.
7. Use the restore option in TWRP for restoring the backup, and the go to Reboot -> Bootloader and you will be in Fastbood mode again.
8. REPEAT the "4" step, but THIS TIME use the FLASH ALL AND LOCK option.
I hope it works!
Ps. Im from Spain, so it could be some grammatical mistakes xd

Just bricked

Okay so yesterday I decided to finally try to install TWRP to flash a custom rom on the system, but never thought it would give so much headache. My drivers were bad, the system locked and android 11 updating making the phone all sorts of bugs, I was anxious to get rid of it, and I did somehow. I was unable to flash TWRP into the recovery as the system partition type is different than usual for it seems, but the recovery partition was all weird, "no command" was stuck in the screen even after a hard reset through there. So I got Magisk and got Root and used Smart Flash to install TWRP through the running system and it landed successful. But when going to the recovery the TWRP screen was flickering, but I could send ADB commands yet and boot normally, I just couldn't access the recovery functions yet. So I flashed a different version of the TWRP with the IMG and the zip folder and nothing worked then I realized that maybe I should erase the partition before flashing it and then the murder. I found a tutorial on erasing stuff, but the whole process cost me more than twelve hours as I messed with so many things and was kinda learning the hows and dos.
But then I saw the command "fastboot erase system -w" that was a shortcut for all cleanup processes and I was wanting to wipe it again even to recover my google backup and be able to use my messenger apps. But it did erase, of course, the whole system and everything, simply destroying everything, but yet stuck in the fastboot screen. What I did? Well, I downloaded the TGRZ of an older version of xiaomi mi a3 firmware, the android 10, as I was tired and thought that maybe if I downgraded it I would get my phone to get rid of android 11 bugs and sleep for good till tomorrow, that is today. I ran the script to wipe anything and install the system over it and it did successfully, then the message "successfully installed, press any key to finish" but then the prompt closed and the phone tried to reboot but fell into a hard brick. The computer recognizes the device as the name "QUSB_BULK_CID:0411_SN:EFCF04FD" and the hardware ID "USB\VID_05C6&PID_9008" matches the original.
So is there anything I could do yet? Phone warranty ended in january and that's why I tried that process, it is any worth?

well it seems I recovered it back, I bricked it and somehow it just got into EDL mode without cable or opening it up. So I found a tutorial back on reddit showing how use GFIL to install the stock rom back. I used android 10 stock rom before bricking it, but as I just flashed everything on empty partitions it didn't work, it seems that the Qualcomm setup needs some kind of previous work to set everything up. Anyways I managed to boot it, but now I'm aware that I should use Lineage recovery instead of TWRP as Mi A3 support is lacking, that's why after installing it I got it flickering (no compatible version with the latest Android 11 firmware).

Pixel 4a stuck in fastboot mode

Tried to follow this guide to root my pixel 4a and completed all steps up to 3.4. My phone is now stuck in fastboot mode and I can't get into recovery mode to do a factory reset. Not sure what to do, I'm a little lost. I accidentally used this or this image for Android 10 when I think I should have used this image for Android 11.
Any help would be very appreciated.
Maybe you can use this guide:
[GUIDE] UNLOCKING, DOWNGRADING TO A10, TWRP, ROOT
Hello, I'm posting this guide for those (like me) who can't do without TWRP on their device. I'm providing only a step-by-step explanation. Credits to @nikamura for his kernel and TWRP...
forum.xda-developers.com
And start on this line in "First Step" section:
Plug the phone into a usb port of your pc.
Then complete all the tasks in "Second Step" section to get your phone at least booting in android 10.

Hello. Currently stuck in fastboot mode. Using the volume buttons to select recovery mode and pressing the power button to go into it doesn't take me to recovery mode. The screen briefly goes dark before entering fastboot again. I think the phone is trying to restart but not getting past fastboot mode.

Can you type fastboot reboot recovery and get into recovery mode? You'll see a little Android guy with a red thing if you're in there.
If that doesn't work- it almost sounds as though your recovery partition is deleted or something. You can reflash the recovery from fastboot.
Hey, I had the same problem. I've got it resolved now and wasn't able to find any help on how to resolve it, but this thread is as close as it came, so in the off chance that somebody else comes along, I thought I'd write up the steps I took.
Because it was in fastboot mode, I was able to easily restore my phone to factory settings by running flash factory image script I downloaded here.
My original image was sunfish-rq3a.210605.005-factory-be541467 which I followed the steps with but couldn't get it to work. I got to the Google logo with a status bar that just ran forever. But the flash-all.sh script worked to get the phone booting again.
So what I did to get Magisk to work was to use that same factory image site to download an older version. I used a version that was listed in a different root guide with the idea that maybe the version I tried before wasn't compatible with magisk, but presumably the one from the guide was. So I tried sunfish-rq1a.210105.002, ran the flash-all in fastboot, and confirmed that it booted--it did.
Next I redid 2.2 through 3 and it worked, and the boot completed with Magisk installed. Everything seems to be working fine now.
