[Guide] [How To] Android Nougat Developer Preview with Root/Encryption/Data - Nexus 6P General

I've been meaning to write this guide for a little while now, but I've only just gotten around to it. Basically, I had wanted to try the N preview, but TWRP didn't play nice with it, so until now, it has been impossible to run N with encryption, root, and without wiping your data. In the interest of full disclosure, I found the basis for this solution while down a Reddit rabbit hole in a very short post at the end of some thread that I've been unable to find again, so I can't take full credit. Many thanks to this random Redditor.
I originally posted this solution in another thread, but the tl;dr version is this: you have to wait to flash the vendor image from N until you're all done with twrp, but other than that, it's just like you're updating with a monthly security patch. This doesn't require any sort of toolkits or anything else either, so that's always a plus. I'm assuming this would work on the N5X as well, but I don't have one to test this on.
1. Download the factory image of DP4 from here.
2. We're basically going to be following step 9 of @Heisenberg 's guide. So unzip the download as you normally would to update your security patch, and put it in the directory you normally would.
3. Now flash everything EXCEPT the recovery and vendor image. I've copied the code from Heisenberg's guide here for your convenience so you don't have to keep switching pages. If you're going to copy and paste that into your command prompt, don't forget to take out the images I listed.
fastboot flash bootloader C:\angler\images\bootloader-angler-angler-xx.xx.img
fastboot reboot-bootloader
fastboot flash radio C:\angler\images\radio-angler-angler-xx.xx.img
fastboot reboot-bootloader
fastboot flash boot C:\angler\images\boot.img
fastboot erase cache
fastboot flash cache C:\angler\images\cache.img
fastboot flash recovery C:\angler\images\recovery.img
fastboot flash system C:\angler\images\system.img
fastboot flash vendor C:\angler\images\vendor.img

4. Now that that's done, we're going to go to your phone. Use the fastboot menu to boot into twrp. At this point, you should be able to enter your lock pattern/pin/whatever, and then flash SuperSu as you normally would. IIRC, you'll need v2.74 or higher, which you can download from here.
5. Now using twrp, reboot back into your bootloader. Fastboot flash the DP4 vendor image that we left out earlier, otherwise your phone won't boot.
That's it! You can now boot into system, and you'll be running Nougat DP4! The first boot took a while, and looped a couple timed for me, but it worked, and I've been running DP4 without wiping my data, without decrypting, and with root for a couple weeks. Remember, twrp won't work with the N vendor image installed, so if you want to use twrp again, you'll have to reflash the M vendor image, and then reflash the N one after you're all done. I haven't tried this yet, but that's what I intend to do when it comes time to update to DP5, whenever Google releases that. Happy flashing!
UPDATE: Confirmed, this method does work to update to DP5 from DP4.

Reserved

I'm going to try this.
Really want root on my sh**t.
But, theoretically, when DP5 is out, you'll have to do everything again, but with the Vendor image from DP5?

By how some people roll around these forums, I'd remove the lines from the copy/paste box-thingy you did... haha.
Edit: fell on my a**. Reminder for me to be more helpful

Quite honestly if someone needs a guide they don't need to be flashing.
They need to do the proper research and understand what each image is. Just my opinion

Kudos. Always good to have a write up with steps for folks. Thanks for contributing. [emoji6]

Thanks for this post; I think it really helps having a quick reference for something like this. I can confirm that if you need to re-access TWRP, you can just flash the marshmallow vendor.img over adb, boot to TWRP, do what you have to do, return to bootloader, flash the nougat vendor.img in adb, and continue using your device. I had to use TWRP to flash the Adaway systemless support zip and doing that sequence I listed above worked as expected. It's not as ideal as having TWRP function with an encrypted device as it does on marshmallow, but at least it works.

Worry not, dear friend as I was also a noob back in '08/'09.
We all learn new things every day. I'm just saying that there are dedicated threads to help with newcomers and guide them step by step.
Edit: You're right. Thanks.

When booting into twrp, will it prompt you for a pin/password? I never set one and I'm afraid it will make me have to completely wipe my phone.

Sweet! This was easy peasy and didn't lose my data. No serious issues, either. Thanks for sharing this info.

To be honest, I'm not sure. I've never had to deal with twrp and no password. I wouldn't think it would reset anything; I assume you just won't have to enter a password..?
What do you normally do for twrp?

thanks for the guide. Do you think if I'm already on DP4 I could flash the vendor image from an M build and continue from there?
edit: it worked!

Thank you this worked like a charm! Switched from a rooted+busybox stock build to rooted DP4. Now waiting for DP5

No problem! Glad it worked for you!

Just upgraded from my stock M + rooted + busy boxed + xposed build to DP5. TWRP and SU both working. Thanks for the guide.

Just updated to DP5 using this method (all flashes but vendor and recovery, flash M vendor, boot into TWRP, root, reboot to bootloader, flash DP5 vendor). Works perfect.

Works on un-encrypted as well. Flashed bootloader, radio, boot, cache and system, reboot TWRP to allow modification-back to bootloader and flashed modified boot.img. Then boot to TWRP, adb sideload SuperSU-2.76, reboot bootloader and flash vendor.img then reboot system. Profit! Still unencrypted with no loss of data and root retained.

Thanks for the extra info!
Question: doesn't twrp work with N as it did with M if you're not encrypted? I thought the issue with twrp and N was due to twrp's code not being able to decrypt - and that was the whole reason people were using the modified boot.img and decrypting was so twrp would work.

I can also confirm that this works with DP5. Will be updating OP shortly.

Oneplus Two - Solution for Hard Bricked Device

Hard brick for OPT happens when you change critical partitions. It will follow improper firmware flash or accidental erase of certain partitions. The phone won't show any response when hardbricked.
The solution for OPT is similar to OPO - you just need a Qualcomm driver and a recover package. The only full recovery package available is very big and it restore the phone to Hyrdogen OS, with everything wiped. So it would not be very attractive.
Fortunately, thanks to this post from Chinese supporting forum, a minimal version of restore package is provided. It does not wipe user data and guarantee a recovery entry. you would normally be freed using this package. if not, please use the full package in the end of the post
Download link for driver
Download link for Recovery tool
uncompress the files to a local folder.
First step, turn off drive signature enforcement in windows 8/8.1/10. Tutorial Here
Second step, hold the power key for 20 seconds to force turn off power. connect OPT to usb, hold volume+ and power until your PC finds a new hardware (if it doesn't work, try hold volume+ and volume- together)
Third step, go to device manager in your PC, find the new "QUALCOMM-HS USB Diagnostics 9006" device. Update its driver in property page using the Qualcomm driver provided (for 32bit windows, select x86 folder; for 64bit windows, select x64 folder).
Fourth step, when the driver is installed properly, run MSM8994DownloadTool.exe in the recover tools folder, using admin privileges . Clear start in top left corner and wait for it to finish.
Now your OPT should be able to enter TWRP recovery. It still won't boot but you can manually flash anything again (like the full Oxygen OS package).
The procedure is tested by me twice. Enjoy!
p.s: sorry the recovery image in the A2001_save_brick_mini.rar is Chinese. Please download this file, change the name to recovery.img and substitute the file in the recovery tool before flashing.
UPDATE:full Oxygen OS 150805 restoration package for those who experience recovery entry problem. Note that this package wipes everything including internal storage!
Awesome, I will go ahead and make a full recovery tool that includes these files as well as the latest version of OxygenOS as I did with the Oneplus one.
You write about a full Oxygen Package? What do you mean with it? a flashable .zip or fastboot .img?

Hi,
anyone knows how I can force the OnePlus Two to enter QUALCOMM-HS mode?
I have a "semi-bricked" OP2.
It can boot, but the recovery is broken and I cannot enter it anymore. Worse enough, the bootloader is locked and I cannot unlock it anymore.
So I am kinda stuck and thought this manual would bring me back recovery. But - I cannot get it to enter this specific emergency recovery mode as boot loaders are intact.
Any idea?
Thanks
Andi

Hi,
ok, I am one step further now.
I could bring the device in that mode, flashed via this recovery tool. All partitions were flashed but still no recovery. How can that be? ooops.
I did that many time on my OPO already successfully. But of course with the full recovery package.
So question is, I would not mind starting from scratch... anybody knows where the "big" recovery package that erases everything is available?
Thanks

I'm in a similar situation to you. I lost my recovery and somehow my boot loader is locked again. I can't set OEM unlock as I am on the old version of OxygenOS.
I tried the above instructions but they don't work. The phone reboots as normal, not in to recovery. If you solve this then let me know.
EDIT: I think flashing hydrogenos using this method is the best idea. We can then select the OEM unlock from developer settings, use fastboot to unlock the bootloader and flash a new recovery. The question is how? @qwsdert4

Hi, I got the "big recovery package" in question from OP support centre in China. It will recover your OPT to factory Hydrogen OS from which you could start over. I'll upload it onto Mega very soon so stay tuned.

Precisely, that is exactly what I meant. Fingers crossed that will solve this.
It could be I successfully recoverd following a hint by user @Zyxxeil (many thanks for the help).
If all works I will post soon what I did.
But - have everything running now again. Next I try to flash twrp again and root. If that worked, I will post the steps.

THANK YOU ONCE AGAIN @ShinySide!!! Not only for root, but now for a working custom recovery. Truly the 2 most important tools we could have for our phone.
FOR EVERYONE ELSE:
As usual, be sure to give @ShinySide your Thanks/Donations/etc.!!! He deserves it! Also, now that you have TWRP you might be wondering what to do next. Here are a couple of suggestions of things that I've already done and that I am quite happy with.
1) Theme it! - Here are some themes you can try out that will not only make TWRP more beautiful, but also provide a layout that is more intuitive and user friendly. These are listed in a Galaxy S2 thread yes, but I've attached a picture of the one that I'm currently running and I'm happy to say that it works on our phone like a charm. I've also used these themes on other phones in the past. Just follow the instructions in the OP of that thread and give the guy some thanks on that thread if you like them. There is no risk in this btw. Either it works or it doesn't and to get rid of it if you don't like it you just have to delete the theme folder that you placed in TWRP. (Try to use the files that say "480x800" as that's the resolution of our screen.) Here is the link: http://forum.xda-developers.com/galaxy-s2-plus/themes-apps/theme-materialised-t2933979
2) Add the Xposed Framework - Go to this link here: http://forum.xda-developers.com/showthread.php?p=62377731
Then, install the Xposed app from the link on that thread. After that, you're going to want to pick the file attached to the OP of that thread that is called "xposed-v80.0-sdk22-arm-custom-build-by-wanam-20160211.zip" and save it to the root of your external SD card. (Do not download the one that says "ARM64" in it. Just the one I mentioned.) Then, just flash it via TWRP and reboot. You should now have the Xposed Framework installed. Once, again be sure to give the OP thanks on that thread too!
NOTE: After flashing Xposed it may hang on the MetroPCS screen on the next reboot for up to 15-20 mins or so while it's doing stuff. If it's any longer than that, then just pop the battery out and reboot. It will boot properly after that while it reoptimizes some apps.
OK something not right everytime I flash the twrp I keep getting the 2.8.70 instead of the version of This 2.8.1.0 one I need help cause everything is correct I keep getting that old version instead of this new version but twrp 2.8.7.0 still works good but I want the version right here

It shouldn't be doing that. Also, you should just make sure your TWRP is properly installed first before you do anything else to it. Maybe try rebooting your phone just by holding the power button once instead of selecting reboot system and see if it boots correctly then.

Again, it is supposed to be 2.8.7.0 . Don't go by the picture I posted it was just a sample of what I had. Not a screenshot. Also, it doesn't need to look like mine to work. Theming it was just for fun and should only be done after you've successfully installed TWRP. Anyhow, try flashing this stock recovery file here. Then, boot into stock recovery and make sure you can still reboot to Android from there. If so, then go back and try flashing the TWRP recovery file again instead and see if that fixes the problem. No one else should flash this file by the way unless they are trying to go back to stock recovery for whatever reason. Thanks!

So, should this NOT work and it continues to reboot to TWRP what comes next? ? Ok, you got me. It continues to reboot into TWRP. I've never encountered this scenario before (granted I've never flashed a custom recovery via ODIN before either, but it went as expected up until I did a backup and tried to reboot into the system) and no, I didn't bother with trying to fancy up TWRP. I don't want TWRP looking unfamiliar. Any help would be greatly appreciated.

Try flashing through ODIN again. Make sure you are in actual download mode (meaning don't use the option in TWRP, use the key combo), and flash it again.
Maybe we could get another youtube video? What do you say, "TheDerek"?

Ok, that's next on the agenda. Gonna take a walk and get myself calmed down before I resume troubleshooting. Thanks for the helpful and speedy response. And the bit about booting into Download Mode using the button combo over the TWRP option - I actually had no idea there was a difference there. I've gathered several boot/recovery zips and tars just in case and am tracking down the T-Mobile version of the g360t1 firmware as well (to cover all my bases, because when it rains it pours ?). Anyhow, I'll report back once I have something to report and thanks again guys ?

I've gathered several boot/recovery zips and tars just in case and am tracking down the T-Mobile version of the g360t1 firmware as well (to cover all my bases, because when it rains it pours ?). Anyhow, I'll report back once I have something to report and thanks again guys ?

So, should this NOT work and it continues to reboot to TWRP what comes next? ? Ok, you got me. It continues to reboot into TWRP. I've never encountered this scenario before (granted I've never flashed a custom recovery via ODIN before either, but it went as expected up until I did a backup and tried to reboot into the system) and no, I didn't bother with trying to fancy up TWRP. I don't want TWRP looking unfamiliar. Any help would be greatly appreciated.

It has to be something you guys are doing during the flashing process that is causing it to boot into TWRP instead of Android. I would try flashing the Trapkernel again from download mode to see if that gives you boot, then if so, try flashing TWRP again. Both should be flashed in AP slot of ODIN. Make sure OEM Unlocking is checked in developer options, etc.
If that doesn't work and it still boots to TWRP, then you may have messed something up in there somehow. Try flashing back stock boot and stock recovery and make sure boot and stock recovery were restored. Once that's working, then you can try reflashing Trapkernel and TWRP. Use this link for more info on restoring your phone and for links to the stock files if you need them.

[Recovery]{Unofficial} TWRP v3.0.0.0 (WQ501)

Welcome to Twrp 3.0.0.0 for our Zenwatch 2's
This release I was able to flash the recovery, flash the supersu zip, and flash some others, so far I have not encountered our wild soft brick madness.
Thanks to @acbka for showing me how to get into log files, essentially helping me figure out why the partitions were not mounting correctly when I compiled and recompiled.
Here is TWRP 3.0.0.0
Directions:
Get into fastboot, either by enabling adb by enabling developer options going into settings, about, and taping the Build number 8 times, and going back, down to developer options and enable ADB Debugging.
Then you can type into your CMD or terminal adb reboot-bootloader or by powering down by holding the button or power down in settings, when the screen goes black, repress and hold the button and swipe the screen from the upper left down to the lower right and that should bring up the ASUS logo with CSC Fastboot Mode! on the screen
continue to boot the recovery by typing fastboot flash recovery twrp3.img
OR load up your tethered twrp and flash the image under that.
Hope you guys enjoy! So far I have not encountered soft bricks so it should be safe and sound
thank you, will test now

Works perfectly, my zenwatch 2 is now rooted
thank you, you`re amazing
Thank you very much! I hope this will be one of the first steps into advanced development for our watches! Does this work for WI502Q? But what's a benefit of rooting this watch?

That im not sure, it might, wouldnt hurt to fastboot boot it and see if itll start twrp. I have the 501
Root will go with modifying the Momentum kernel so you wont have much lag on the watch, and any other root modifications that can go with it, like maybe xposed?
Next step in development is fixing twrp so it can be flashed, then maybe modifying the wear os? Or maybe porting some stuff

what did u flash to get root? the one twrp offers (if this one does)? the one xda tv featured for 5.0.1 wear http://www.xda-developers.com/root-android-wear-5-0-1-xdatv/ ? or just the newest non-systemless supersu.zip used for phones? with a phone i would just flash away anything. but im a bit hestitant on the watch yet. couldnt find clear info yet.
Awesome! Got supersu flashed and was able to use Advanced Settings to disable some of the built-in bloatware apps. I'll have to try out the kernel but I'm currently at work and don't want to spend all day messing around with my watch (well... I want to, but I like not getting fired).

You can tell twrp to preserve the system protection, back every single thing up that you can in the twrp option, push that backup to your computer, and then you can disable system protection. twrp itself wont do anything, however playing with options will modify the watch.
OR you can fastboot pull things off the watch, the system.img and boot.img yourself, in case the ones uploaded in my general thread didnt have the protection enabled.
If you want to hang tight until 1.4 comes out, that can be a good thing too
And im not sure if there is something like that on the watch. I have not seen anything about it before
My attempt was a failure on my WI502Q. I got the following messages. And, OP, how do you pull system.img from a device through fastboot? I thought you needed root permission to do that through adb.
"
C:\adb\zw2>fastboot boot recovery.img
downloading 'boot.img'...
OKAY [ 0.381s]
booting...
FAILED (remote: dtb not found)
finished. total time: 0.834s
"
Thanks for this! I was losing hope on any development for this watch but now we have the most crucial component to modifying anything on android, a custom recovery. Going to perform a backup, root and flash your custom kernel you kindly released as well!
T10NAZ said:
Hello everyone, I have been working hard last night to make twrp run on our watches, and this I think is a good representation on what itll be like with actual development going on
As far as I understand people are able to get backups of their watch in order to preserve OTA's before rooting, and I was able to flash some zips and kernels successfully, and I fixed the UI to look better and actually usable on the watch
Also, I was able to flash this puppy, and I got android wear to boot with it flashed, however most of the time, it goes haywire and only boots into recovery. Same thing applies, this shall be a Tethered recovery only until I know why its going crazy.
As always, problems can arise on your watch, so be careful!
read the entire instructions, This is a known way to get system protection off, and to flash zips/kernels when need be. Do not flash please.
Here is the link to the updated twrp
Get into fastboot, either by enabling adb by enabling developer options going into settings, about, and taping the Build number 8 times, and going back, down to developer options and enable ADB Debugging.
Then you can type into your CMD or terminal adb reboot-bootloader or by powering down by holding the button or power down in settings, when the screen goes black, repress and hold the button and swipe the screen from the upper left down to the lower right and that should bring up the ASUS logo with CSC Fastboot Mode! on the screen
continue to boot the recovery by typing fastboot boot recovery.img like the other one.
I also have a kernel underway if people would like to try it out and test it in the next couple days

it could lead to that, yea, since this is the only root method basically, it adds a few extra steps to do it
can we root with regular supersu .zip, or do we need a special build for wear devices?

https://drive.google.com/file/d/0B3zB2zRyWlLBNmhwSmNBUEp1SVU/view?usp=sharing there ya go. dunno if the regular supersu works. havent tried that out. this one does. and alrdy has a busybox installer wear app included which u need anyway sooner or later.
there is no supersu manager app in it though like on phones. apps requiring root just have it. tested advanced settings so far for disabling built-in stuff and a reboot option. but maybe there is a supersu-wear.apk somewhere?

flash the stock images via fastboot or tethered (NOT flashed) twrp and you should get your watch working again.

Boot Logos!

Just flash the zip in TWRP to change your boot logo. These should work for any model of the G6 Play. All backgrounds are white with the exception of the original boot logo. This was done to cover up that annoying bad key or N/A message. Enjoy!
Hey, thanks for this! If I do a design, could you make it into one of these? For example, this one?

Yep, check back in like 10-15min and I'll make that a logo.
Edit: Done!
Motorola Moon
This took me a few hours. Hope you folks like it. I'll probably make a few more over the next several days.
Is there a tutorial anywhere on how make these?
These are great and just what I need, however, I can't seem to the zip files when I'm booted into TWRP on my XT1922-3 (I think it has something to do with not being able to find a download for XT1922-3_no_dm-verity_boot.img that still exists anywhere). So is there a way to flash this using fastboot?
I tried unzipping and using the command > 'fastboot flash logo logo.bin' which it said was successful, but I still see the bad key or N/A.
It would be great if anyone can explain how to get this to work for me.

You shouldn't need a no verity boot.img
You can flash the dmverity disabler then magisk.
If you already have TWRP, then dmverity has already been disabled. Or your phone wouldn't boot.
But if you need it

Thanks, yes, I downloaded that already and put the zip file into the root directory, but TWRP doesn't see it to be able to install/flash it.
As I don't need the phone rooted, as I'm just setting it up to sell on, I think I'll just reflash the stock firmware and see if I can relock the bootloader and get rid of the N/A and/or Bad Key messages, so it is like oem from the factory, for whoever buys it.

That's because TWRP can't read encrypted storage. Has to on your SD card.
These are really cool! Appreciate you sharing what you made and getting the annoying "bad key" done away with. Did you follow a specific tutorial to make these or you just already knew how? I am interested. I would like to make some is why I ask. I use Ubuntu on my home computer and I have gimp. I haven't ever really messed with it much but I plan on setting down with it soon ,hopefully this weekend and this would be a cool project I believe to start out. I'll search around here on xda and see what all I can find on boot logos. Thank you! Also thank very much for the custom twrp recovery!! If it wasn't for you I don't believe the Moto g6 play would be able to install GSI roms. :good:

[GUIDE] How I flashed TWRP, Xiaomi.eu rom and rooted with Magisk

Hey guys.
The below is my full experience of how I flashed TWRP, the Xiaomi.eu rom and rooted with Magisk. Whilst it essentially is a step-by-step, it also contains not only how I succeeded but also how I encountered issues and so...
*UPDATE!*
Here is a slightly condensed verison with thanks to @airwebber
Get the latest xiaomi.eu rom from here or here, just scroll down and find the "xiaomi.eu_multi_MI9..." version.
https://sourceforge.net/p/xiaomi-eu...ty/?page=0&limit=100#5cb9f96ee8ba7c44716e87ff
Get the latest magisk (magisk v19 works at the time of writing this post):
https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445
Some versions of twrp may not work on older builds other than the latest (9.4.25) and so use this one with:
https://mega.nz/#!CH5jgYTB!yNqOiVoo3cf0_15jIwZ-btO52cvpOG7iZrRCe19V2Nc
Once the waiting time elapses (usually 360 hours) use the MiFlash tool to unlock the bootloader. Warning: this wipes your phone entirely, so be sure to backup anything of importance.
Unlocking takes a few minutes and once 100% complete your Mi 9 will reboot. Your phone will say “unlocked” on the first splash screen while booting up.
Your Mi 9 will boot, and you will need to either perform/skip the initial setup stuff. Once ready, power off your device in order to flash TWRP.
Press both the volume down key and power key to boot into Fastboot Mode.
Once in Fastboot Mode, use the following command to install TWRP: “fastboot flash recovery XXXX” (XXXX = the pathway to your TWRP.img file). However, I find it best using Minimal ADB and copying the TWRP file and renaming it to “twrp.img” for ease) in the Minimal ADB folder location e.g. “C:\Program Files (x86)\Minimal ADB and Fastboot”.
Once flashed, disconnect the USB cable and boot to TWRP recovery by holding down both the volume up and the power buttons. This sometimes will bring you to the stock recovery and NOT TWRP! If it does, boot back to Fastboot and reflash TWRP.
Once you can boot to TWRP, push both the rom and magisk via CMD line:
adb push rom.zip /tmp/
adb push magisk.zip /tmp/
For ease, I suggest copying both files to the Minimal ADB folder location e.g. “C:\Program Files (x86)\Minimal ADB and Fastboot”. And renaming them to: “rom.zip” and “magisk.zip”.
This step is very important!! You must go to the Wipe menu and select: Format Data, then type “yes” to continue and then: do a Factory reset, which also wipes: Data, Caches and Format Data. If you skip this step you won’t be able to install a lot of important apps and will have to start over.
Now that you have pushed both the rom & magisk and wiped everything you needed to. Install the ROM immediately after install magisk.zip (in that order) both located in /tmp/.
The installation will take a couple of minutes (if your screen dims, don’t worry that’s just TWRP screen dimming, touch the screen to keep it awake!) once finished with no errors, then reboot and chose Do Not Install the TWRP app when prompted.
The phone will take a few seconds to reboot and show the first MI splash screen, but it should start booting. After a couple of minutes, you should see the initial boot screen! Perform the setup (connecting to Wi-Fi, adding my Google account etc.).
Once finished setting up, you may notice that magisk was not installed, if that happens, you can install the APK version and follow the prompts and reboot.
Once rebooted, confirm that magisk is now installed. If it is, I suggest installing SafetyNet and confirming your phone passes!
If it passes, you have successfully installed and rooted the Xiaomi.eu rom!
Also, when updating with each weekly I recommend the below as an alternative to using the built in Updater app. The reason being is I believe the updater app automatically reboots after it installs, which if you're rooted means you'll lose it. That then means you have to reboot back to twrp, reflash magisk, reboot, reinstall modules, reboot again etc.
Therefore to update a weekly:
Download the rom manually
Reboot to twrp
Wipe system and caches
Flash the rom and magisk
Reboot
Optional: I also disable my substratum theme too before updating and reapply afterwards. Whether it's needed or not I'm not too sure, so give it a try either way
Awesome, all files at the ready! BTW get the latest MIUI from HERE or HERE.
Make sure you download the xiaomi.eu_multi_MI9_xxx.zip.

Thanks for the detailed write up. The EU roms are google approved correct? Does the side Ai button work with google assist? Do you need to install twrp to flash or can I just flash global/EU rom if I don't want to root yet?
I just got the bootloader unlocked (1h before than I tought ahahah). I had some issue that the unlocker was telling to me thaat I didn't use enought the phone and that so I had to try in few days I overtook the problem using an old version of the unlocker (2.3.803.10).
Reading your procedure it all logical and fine, thanks! Except one thing that I'm not sure... Is xiaomi.eu a 'full rom' (on all Xiaomi that I had I always jumped straight to something different than MIUI and so I never tried it ahahah )?
If so, I think it would be better to wipe the system too before installing the rom. That's because doing so it will do 100% 'clean' installation and not a an update on the normal global miui

Yeah, to change the device name back to mi 9, just install "Find my device" app from Google play store, sign in with google account, there's an option in the setting to rename the device (this device).
That's the only place you can change the name back, I did try all, but only this one worked.
