[Redmi Note 8 Pro ROMs, Kernels, Recoveries, & Othe] camsapphire:
After a couple weeks of suffering the lack of bluetooth caused by the PE ROM, and following all your helpful tips here, i manage to fix it.

However, it still got me a while... when i first read this guide by @SansSerif_ , the 8th step made me think that if I just followed the clean flash instructions for PixelPlusUI everything was going to be fixed. However, it will not! You really, really have to follow the step by steo guide they provided on the post.

Some tips that may help you:

1. Make sure the hashsum of the files you downloaded matches the MD5 or fingerprint given by the ones sharing it (ex, the xiaomifirmwareupdater page). You can check the checksum via the terminal, or with a software. If you are on Linux, gtkhash is really easy to use! I said this because one of my downloads was paused by a few minutes, then restarted, yet something broke and that left me with a soft-brick. Please be careful! Better safe than sorry :D

1.b. Make sure you have the ADB tools for your computer installed/on your $PATH. Since i am on ArchLinux, i installed android-sdk-platform-tools, android-udev and android-tools from the AUR, and had no problem. Make sure to read some guide or watch a video for your specific OS.

2. Might be obvious, but, do it when you are sure you will have time both to a) flash the device b) fix it if something gets broken (which includes re-downloading the roms). Also, make sure you won't need the phone while doing it so (i just pulled an allnighter to do it calmly). Also, if you want the download to go faster, consider using a downloads manager. I really like Motrix (Linux, Mac, Windows; + browser addons) and JDownloader2 (Windows).

3. After I followed steps 2-7 in the previously mentioned guide, and tried to finally flash PPUI, i found that my TWRP instance had dissapeared, and i was redirected to MIUI's recovery instance. Added to that, the TWRP that the PPUI page does not work via fastboot, and if you happen to lose your TWRP instance like i did, you will need to re-flash TWRP via fastboot. I tried downloading the official builds provided by TWRP's page but none of them worked. However, i had been using Greeshan's MIUI repack and he actually provides a TWRP .zip that you can flash via recovery, or extract and flash the twrp.img via fastboot. Here's the link to the post and here the link to the download itself. There's a link that says you can download the .img file on a forum, but the link is broken. Download the .zip instead.

4. If you take into account this considerations and follow the guide provided carefully, you should end, like me, with a beautifully and fully working PPUI experience.

About the ROM itself, two things: if your frontal camera is not working, check if you have allowed the "Force 64 Mp" in the BegoniaParts settings. When i disabled it, my camera worked again.

I also had some trouble with android's native file manager ( com. android.documentsui ). What i did was, first of all, disable the app itself. I did it with AppManager, but you can also achieve it via the native android settings. Then, I installed MiXplorer via this magisk module. That fixed everything. I guess that as long as you disable the app and install your favorite file manager, you are good to go!

Hope this help. This ROM is my favorite so far, and I'm grateful for the hard work of those working on it :3
