Bluetooth problem after flashing TWRP

[vasik006]

Hi,
I flashed TWRP on my unlocked Redmi Note 8T with MIUI Global 12.5.5. Everything was great until I rebooted it and saw Bluetooth error which pops every time I try to turn Bluetooth on or just randomly during usage of the device. I also tried to re-flas TWRP with Orange fox but it unfortunatelly did not help. Now I have no idea what to do but there are also some other people with this problem (for example: https://www.reddit.com/r/Xiaomi/comments/y9zsak ).
Does anybody know any solution? Thanks!

Btw Orange fox is for ginko devices, I did not find version for willow

I had the exact same problem when I tried to root my stock rom in ginkgo. I was getting a lot of "app keeps stopping" pop ups, and that also included bt. My bt was completely broken until I changed rom. Also I'm guessing this had happened when I had rooted my phone with magisk, not by flashing recovery itself. Perhaps you could try to uninstall magsik, and see it it resolves the issue for you. If that would be the case, then you would have found your problem, and maybe you can flash a custom rom to safely root your phone.

Thanks for reply, but i did not have magisk flashed on my phone. I only had installed the app, prepared apk file and did nothing in TWRP (Orange fox) , just flashed a recovery with my PC, checked that it is working and rebooted device. Anyway I tried to do it only because of acces to NFC and Gpay which is now blocked.

As you also said, I would like to try custom rom (like LineageOS) because it seems like bad idea to have a stock room on an unlocked phone. Only the problem is how to backup data like data from apps, games etc.

So now it tried one of my ideas, which was to install Magisk (root) and uninstall it but it also did not help (I expected that)

To backup data simply copy your personal files in pc or sdcard. And to backup data in apps, take back-up of only those apps and where you need to backup. Don't take a complete backup using some app. That consumes a lot of space and make the newly rom feel "not so new". Most apps don't require you to take back-up offline these days. I usually backup only my personal files before flashing rom.

 

[vasik006]

Yeah, that's true. But don't you know how to backup data from these "offline" apps? I was trying to solve this also before unpocking bootloader like a year ago but unsuccessfuly.

Also, which rom should I choose? I'm deciding between LineageOS and Pixel experience.

So I have LOS installed but I can´t install other zip files (like Google apps). Im only getting error: signature verification failed while. Im using LOS recovery so where is the problem?

Solved it!

Hey @vasik006 ! I know this is very late and you might have found the solution yourself, but I found the solution to this problem. Since yesterday I was trying to root my ginkgo with twrp, using magisk delta and had exact same issue. Joyose and bluetooth keeps stopping, and don't work. Simply factory reset ( I also formatted data) in twrp, and in next boot bluetooth should work. Then you can simply install the magisk apk and let it do its thing. No need to flash again since it has already made changes to boot file that can't be overriden by resetting phone.

 

[vasik006]

Thanks, this might help someone else with this problem. I have already formatted my phone, installed Lineage OS and everything is ok

For me, the problem with BT and Joyose occurs only with TWRP v3.7.x. I went back to TWRP v3.6.1_9-0 but now backups are not working.

I have the same problem with the Redmi note 8. Did you unroot first or did the factory reset directly? Tks

no need to unroot. simple factory reset the device and you're done.

TWRP is invaluable for backing up the system before making changes like theming etc. and I can take a TWRP backup to any of my (all the same) devices and restore the whole thing in just a few minutes. So convenient! I really couldn't imagine life without TWRP. TWRP enables me to clone my device in case of hardware failure. All my settings and all my apps and all my custom configurations which would otherwise take hours/days to setup - BAM! Presto! on the new device and running perfectly.

TWRP + NeoBackup are essential. TWRP as described, and NeoBackup to roll back breaking updates to apps when devs butcher them, break them, and/or just remove really useful features. I also disconnect apps that get ruined by an update from the Play Store so they don't keep coming up when I check for updates.

I would advise you to read the posts again. They were asking about how to take backup of "personal apps" which twrp can't do, and if they are changing ROM then twrp backup won't be of any use to them. Therefore, whatever you're trying to tell here doesn't really help the discussion.

TWRP does backup personal apps and their settings. Once you restore a TWRP backup, you have everything back except media files - images, videos, documents, etc. The launcher icons, the apps, the system settings - everything is a perfect clone which you can restore on a new device (same model, of course).

I actually came across this thread searching to see if others had a problem where merely flashing TWRP caused Bluetooth to crash (and Atmos).

Use OrangeFox

is there anyone use BT-fix-for-PE-20190618.zip to fix this problem ?

 

[Dredead]

I'm on an ROG Phone II with the same issue.

The "fix" is to wipe in TWRP and install Magisk BEFORE you leave for your first boot and NEVER come back to TWRP as the issue will return the second recovery is booted.

For me, the problem with BT and Joyose occurs only with TWRP v3.7.x. I went back to TWRP v3.6.1_9-0 but now backups are not working.

From what I can tell, this is correct. 3.6_XX-X allows me to come and go from TWRP as much as I please without incurring the bug, however, I haven't tested backup though I can't see a reason why they wouldn't work.

Are these existing backups that aren't working or the whole backup function in general?

It looks like this guy didn't have any luck with it either. It may be divice specific

amazing, I have do nothing, just reboot my device, and yesterday the bluetooth also has problem, but today I open bluetooth, it is no problem. I'm still confused about that.

It seems to be a twrp issue. What version do you have? And what version of magisk do you have?
I have recently flashed miui 12 (android 10) after bricking the phone using qtel. I noticed the Bluetooth problem last week and didn't find a fix. I have twrp 3.6.2 and magisk 25.1. I had twrp 3.7.1 but if failed to decrypt data using pattern so I rolled back to 3.6.2. And I thought that magisk had to do with the Bluetooth problem so I rolled back to 25.1 from 26.
I still can't use the Bluetooth, and I don't have time to reset the phone, I just finished restoring everything

 

[Olfason]

I CAN CONFIRM

go back to the previous twrp 3.6.2 version + wipe factory reset or simply format data solve sucesfuly solve installation issue of Magisk 26.1 or Magisk Delta 25210

I can't afford resetting my phone right now , don't have enough time. I'll let it like that for some months.

Edit : I have miui 12.0.6 installed (android 10) and I'm not planning to upgrade since I have much better battery life (even better than every mod I tried). I wander if I flash miui rom from recovery can fix it?
Edit 2: flashing the rom from recovery didn't fix it
