[Redmi Note 8 Pro Guides, News, & Discussion] dcindallas:
So I've read enough posts to get this first - GLOBAL ONLY I got my phone on Amazon its a global unlocked NOTE8PRO. Any of you with something else like China or India try this method and brick your phone don't cry to me over it. After trial and error, bricking my device and paying some guy in Spain 30EUR to unbrick it (thanks brother you rock) I thought I'd share my final experience and how you can get your GLOBAL RN8P to a stable place to install the ROMS available at this time. I will include at the end my thoughts on the 2 ROMS I installed and used over the past week. Honestly if you're on a global version I'm not sure it's worth it although as I type this I kinda want to flash Pixel Experience again, I really liked it. But more on that later. I compiled this guide from sources here, if I don't give you credit I apologize in advance please just let me know.

First let's make sure we don't brick this mofo.

Hit the MEGA thread if you haven't read it then you shouldn't be flashing your phone, and do this from a clean install of MIUI-V11.0.6.0PGGMIXM and do yourself a favor and get it from Xiaomi or a reliable source, not everyone on here has good intentions. There are some "official" ROMS out there that have been played with and will break your phone.

1. Do it how you want I did this from fastboot. Dump the official MIUI global ROM in a folder, and (I'm on linux box so adjust yourself if you're sadly using Windows) I executed this command from FASTBOOT in the MIUI ROM folder with ADB and FASTBOOT installed for my system.

./flash_all.sh (I think its flash_all.bat for Windows)

This going to wipe your stuff out, have it backed up. I'm dedicated to Google and GDRIVE I don't care I get everything back when I wipe including sms and phone records etc, but to each his own.

It's going to wipe and restore to factory image on that ROM version and you're going to go throught setup again, tedious (I say that having done it 4 times this week) but none the less it is what it is. After you are up and running on that ROM version keeping in mind if you're going to flash a new ROM like PE then don't set it up all the way because you're going to do it all over again anyways move to the next step.

2. From the MEGA thread flash this and reboot. Read the thread download the files and do what Agent_fabulous (awesome guy btw) says. Reboot. Make sure you can reboot to SYSTEM and all is well, don't worry about recovery or bootloader yet.

fastboot flash preloader preloader_begonia.bin
fastboot flash lk lk.img
fastboot flash lk2 lk.img

3. OK kids we're almost there, now you need to install TWRP and there are MANY versions floating around. Honestly the official version sucks IMHO. go to this thread and download TWRP and do exactly what it says in the thread. Assuming you're device is unlocked already and if its not then come back later follow EXACTLY steps 2 and 3. From there you will update MAGISK after the reboot and be fully rooted and pass SaftyNet checks.

You are stable and rooted. All you do next is enjoy your rooted device and or install a custom ROM. If you do install a custom ROM - READ READ READ and FOLLOW directions I hate to add to the confusuion but there are so many threads on this phone (becasue it sucks to MOD it) and it's frustrating because all of it assumes you know everything or they just don't give you all the steps and you end up bricking your phone. I have never by the way rooted or flashed a phone in my life before this one.

At this time all the custom ROMS need to be flashed after flashing the Indian Vendor image, this is in fact the only way I know and it worked for me everytime. So at this point if you're flashing a new ROM first flash the India Vendor image then flash the new from all from TWRP. But in my experience just follow what it says because Agent_fabulous and friends may crack this tomorrow and it won't be the same. What I am giving you is a VERY stable platform to start flashing ROMS from or just to be rooted and happy. As an FYI from this you can install RIRU and EdXposed if you want to do that, I wasn't impressed other than dark mode in GMail on A9 and ad-blocking in YouTube, I get the ads in YouTube but Google no dark mode in GMail on A9? WTF??

Happy rooting and ROMing.
