I have IN2010 with OOS 11.0.8.8 IN21AA. I want to downgrade it to the same international firmware. Is there any risk of losing fp or any other problem can occur?


edit: i have tried it using global OOS 11.0.4.4. But i have problem where it says param preload fail and just stuck there. It is too long so I decided to plug off the cable and reboot the phone. No issue with the phone after that.

I have tried this two times but still not working.

I can't really tell if my OnePlus 8 is actually bricked or not, but I have not been able to turn it on
for 2 days now. I tired running the tool while holding down both Volume +/- but as soon as it gets to "Start Download Firehose" something or whatever it says, my computers makes the sound of the device being disconnected and it immediately goes to "Try Firehose Communication Handshake" and then fails.

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 the previous threads for
OP3, OP3T, OP5, OP5T, OP6, OP6T, OP7, OP7PRO, regular OP7T, T-Mobile OP7T, regular OP7TPRO, T-Mobile OP7TPro 5G and OP8Pro here are the EDL packages (also known as MSM tools or unbrick tools) that can revive a bricked unlocked OnePlus 8 (except T-Mobile/Sprint IN2017 ones and Verizon IN2019 ones, head to https://forum.xda-developers.com/oneplus-8/how-to/op8-unbrick-tool-to-restore-device-to-t4093043 and https://forum.xda-developers.com/oneplus-8/how-to/op8-unbrick-tool-to-restore-device-to-t4191723 for that)

You should also be able to rollback your phone to a previous release of OOS with them if for some reason you want to go back to an older firmware :)

You can download the following versions:

IN21BA tools (european firmware):


IN21AA tools (international firmware):


IN21DA tools (indian firmware):


Warning:

As this happened on OnePlus 8 Pro, it is advised to take backup of /persist partition before crossflashing (eg going from International to Indian build) as fingerprint reader may give an error related to enrollment issue. You can do so by using dd if=/dev/block/bootdevice/by-name/persist of=/sdcard/persist.img (you must have root access, which is not something I'm going to explain here) and moving it to your computer/cloud.

Instructions:

Launch MsmDownloadTool V4.0.exe.

On Android 11 MSMs and up Windows 7 users may need to launch MsmDownloadTool V4.0_Win7.exe instead, but it hasn't been tested


On the login prompt select "Other" in the dropdown menu and click on Next.
Wait a few seconds until main window shows up.

Click on Target button and select O2 while using international tool or India while using indian tool or EU when using european tool.
Power your device off.
Maintain volume up and volume down keys to get into Qualcomm EDL mode.
Plug your device to your computer using stock OnePlus cable. (You may let volume keys go once done.)
Click on Enum to be sure your device is detected and press Start.
Wait ~300 seconds.
Enjoy your brand new device.

FAQ:

Does this work on Mac or on Linux?

Unfortunately no, tool is Windows only. You should need at least Windows 7.

Why is my antivirus freaking out when unzipping the archive or running the tool?

In an effort to protect reverse engineering from being done (and by extension prevent conversion process like it was done on 6T and 7Pro), OnePlus now use VM Protect V3 in their MSM tools. As this tries to detect debug environment, this is seen as malicious behaviour by some antivirus.

My device isn't detected when I click on "Enum" button

Go to device manager and make sure your phone shows up as QDLOADER 9008.
If it shows up as QHUSB_BULK, it means Qualcomm driver wasn't installed automatically by Windows Update. Download the latest one from Microsoft website at http://download.windowsupdate.com/c..._fba473728483260906ba044af3c063e309e6259d.cab (source https://www.catalog.update.microsoft.com/Search.aspx?q=qualcomm hs usb 9008 ) and install it manually by right clicking on QHUSB_BULK and selecting "Update driver software" and "Browse my computer for driver software" to where you downloaded CAB file.

MSM tool is stuck on "Param pre-processing"

Ensure you're using the Qualcomm drivers linked above.

MSM tool is stuck on "Sahara communication failed"

Unplug your phone, get in fastboot mode, turn off phone, wait 15 secondes and get back in Qualcomm EDL mode. You can also try using a USB 2.0 port instead of a 3.0 one.

What is SMT Download mode?

Just don't try to unlock that mode, it will wipe your IMEI and your Widevine certificate if you use it.

How can I fix "SMT config not found" error?

My OP (IN2010) Ch Ver was totally hard bricked after getting the qualcomm crash dump. black screen, no fastboot, no charging message when charging. but somehow, when I plugged it in my computer, it gets detected and I was able to go EDL mode. I tried MSM tool, but I always get "firehose communication handshake failed" error message. I'm a total noob so I hope you can help. Thanks brother.
Hello, please, did you fix it ?? i have the same issue with in2010...

Hey there, my OP8 IN2010 is rolling on OB12, bootloader unlocked and rooted. I

I kinda lost my mojo for rooting and I also have been experiencing problems with Magisk and bank apps so I'm willing to give HOS12 stock a go.

I did backup persist.img and its on my PC already. I did download MSM package for flashing HOS and everything needed...however, when I try to open MSM tool 4.0 that comes within this HOS package, it shows an error saying "Tool version is out of date and unavailable", my question is:

Would it work OK if I unpack the MSMTool,exe in this thread package and move it into the HOS folder in order to proceed with the HOS flashing?

I'm asking because I'm not sure if MSMTool.exe in a given flashing package are tied to it in any way or if they are just in there so we don't need to find it, to download it and to move it to the corresponding folder so we can flash away.

Thanks
