Use MSM tool to be safe. Take note that you will be deleting all files in the internal storage upon doing this.

Reinstall Stock and use fastboot command to lock
./ fastboot oem lock
If you want to use custom roms, then keep it unlocked.

No it won't install original recovery. If stock isn't installed it'll brick your phone. Hope this helps.

Disclaimer: By attempting any of the processes listed in this thread you accept full responsibility for your actions. I will not be held responsible if your device stops working, catches fire, or turns into a hipster and claims to have been modified before it was cool.
Hi everyone, similar to my threads for OP3, OP3T, OP5 and OP5T, as only a few versions of unbrick tool are available here and that they allow to rollback to specific versions of Oxygen OS I decided to search for more and succeeded in that.
I linked to version 5.1.5 and 5.1.11 shared by @Fivegates and @Titokhan here and here.
Rest is provided by me.
As the instructions and Qualcomm drivers are already available here, I don't feel a need to rewrite them.
You can ask questions here on how to use and issues, however I might not be able to answer immediately.
Here are the files uploaded on AndroidFileHost ordered by Android version:
ANDROID 8.1:
OOS 5.1.5
OOS 5.1.6
OOS 5.1.8
OOS 5.1.9
OOS 5.1.11
ANDROID 9:
OOS 9.0
OOS 9.0.2
OOS 9.0.3
OOS 9.0.4
OOS 9.0.5
OOS 9.0.7
OOS 9.0.8
ANDROID 10:
OOS 10.3.0
OOS 10.3.2

Thank you for the files! I'm busy downloading the 9.0.4 archive at the moment. One question: I can't find a working download link for the qualcomm drivers anywhere. The Android FileHost link on the linked thread can't find any mirrors:

Does anybody have a different location where I can download the drivers?

That I'm flash a recovery for example so it shows me that I'm entering a black screen or error Qualcomm crash dump mode then the system does not cost me a black screen

Sounds like you did something wrong. In order to receive help you need to write in detail what you did, what files you flashed/used and in which order.
1. i fix my brick with OnePlus 6_Hydrogen5.1.3_hardbrick
2.update to 9.0.5 in update software
3.unlock bootloader with adb pc
4.flash with adb twrp-3.2.3-1-enchilada / twrp-3.2.3-x_blu_spark_v9.96_op6
And when I try to get into the recovery he shows me a blue screen with blue LED light
Or looking at me as an error Qualcomm crash dump mode
And the normal system also does not work after it has to again the OnePlus 6_Hydrogen5.1.3_hardbrick for fixed

Oneplus7pro back to stock

Hello there,
I tried the open beta on the OnePlus 7pro for a while, but I have some massive issues with speaker distortion, so I decided to go back to stock. I know this involves a wipe of the entire system, and I have fully prepared that.
However: I seem to be to stupid to perform this. I used to flash all kinds of roms to my OP3 back in the day, but I can't find an option for simply flashing the zip in the recovery.
My big big question is: How do I perform the full reflash of this phone?
Do I get an factory rom like with the pixel, or do I need to sideload something and flash it in recovery?
I am really clueless rightnow, expecially since the factory image told me, that the bootloader is locked, but to my unterstandig, flashing an original manufacturer image should not require the bootloader to be unlocked...
So I am really hoping on your help, as rightnow, I have a beta phone that is waiting to be setup...
:crying:
Follow this tutorial.
https://forum.xda-developers.com/oneplus-7-pro/how-to/msm-tool-guac-t3934691
Or easier way would be to download rollback package from oneplus which will wipe everything on your phone. You will have os9.5.3
You can then do Ota upgrade to latest os version. Rollback package is listed in in the middle of the post
https://forums.oneplus.com/threads/...-for-the-oneplus-7-and-oneplus-7-pro.1099154/
So my OnePlus 7 Pro is rooted, has twrp, xxx ROM and renovate ice. If I want to go back stock and relock bootloader, can I simply flash the latest ROM (in this way I should loose twrp and root) and then relock bootloader with ADB command?

There is a newer one available search for unbrick tools in forums and also you can use this old one too you have to do local upgrade after that

Thanks bro!!
Local upgrade is a cake walk! All my worry was, if I go for a random version msm tool, which is not specific to 10.3.4(more like the case of fast boot Roms), i may stuck at bootloop/something undesirable.
From your reply, i understand, i can use any msm tool zip that supports one plus 7 pro, and get back to stock with an older oos version in it. From there i can choose OTA upgrade or local upgrade.. Whichever way? Right ?

Yes I used 9.3.4 and then did local update but if you are on 9.3.4 you have to flash first 10.0.3 and then after that 10.3.4 to upgrade.

Have you already tried downloading correct firmware from OnePlus site. And local upgrading?. And you will indeed have to look it up. This all requires some working knowledge of how all this works.

Realme C21Y (RMX3261,RMX3263,RMX3262) kernel source, boot.img....

Hello and welcome​NOTICE:This thread will be modified when new files are available.
Manufacturer: Rea*me
Device: Realme C21Y
Chipset: UNISOC T610
DEVICE CODENAME: RMX3263,RMX3261,RMX3262
Currently available files:
pre-built kernel(zImage) boot.img
device-tree.dtb(device tree blob)
device-tree-source.dts(device tree source)
kernel-configuration file, sepolicy, prop.default
EDIT:finaaaaally Rea*me released the kernel source for this device, I think it is time for you to compile !
https://github.com/realme-kernel-opensource/realme_C21Y-AndroidR-kernel-source/
unfortunately as you see, there is no kernel source and also a way to unlock the bootloader, the files are somehow not very important but maybe in the future they will be.
actually, you can build any custom rom for this device using the prebuilt kernel(zImage), without kernel source by using TARGET_PREBUILT_KERNEL="Path to zImage" variable, if you understood that's good, if not just search for it, then when you got the zip file you can use sp research tool to flash the built from source rom with a locked bootloader, because it is the only way to flash this phone's files with locked bootloader, these are the instructions that you'll need to do(please note that this is a theory only, i didn't test it and i am not responsible for bricked devices, at your own risk !):
Get the phone's stock rom for example from this link: https://romprovider.com/realme-rmx3263-flash-file-firmware-free/
then install the sp research tool(you need to use this one specifically, the sp flah tool works just in the factory): https://androidmtk.com/download-spd-research-tool
Link: then using this link follow the steps until you replaced the stock system.img to the GSI's system.img one.
then just flash it using the tool and you will success to flash the GSI rom.
Next the file device-tree-sorce.dts is the device tree source file.
To get the boot.img, download the boot.zip below, extract it and you'll have it, if you want to modify boot.img download AIK tool: then run the shell script on the boot.imh file(you can do it only in Linux).
well we hope we will find a way to unlock the bootloader, because it's the key for doing everything.
Have you tried realme Deep test App to unlock the bootloader.
Hey I was thinking of flashing the proton AOSP GSI on Realme C21Y. I have checked that realme c21y has Treble SUPPORT so I thought if you can give it a try if you happen to have a realme c21y available.
Here are the links of file and tutorials that I intend to follow .
Tutorial.
GSI ROM link : https://github.com/haridhayal11/treble_proton_aosp/releases/
The problem is that you can't unlock the bootloader. Not about installing a GSI.

The command failed .
The problem is that the device's community is dead. You can't find a griup or something like that to discuss.
Unfortuanately, i don't own that device anymore.

One more question, why is that every GSI that is loaded by this method has some kind of audio problem..
Without audio , this is almost a deal breaker....
Is there any method to use headphones on booted GSIs ??

Greetings, the problem with the headphones is partly related to the vendor, which is natural for A11, but for A12 and A13 it is not yet available, or rather it needs to be updated for this, which is comparable to know very well Same Kotlin.

You can unlock the bootloader only on A11, on A12 it is impossible. You need to go to A11, unlock bl and then go to A12.
