[Moto G9 Plus Guides, News, & Discussion] christjeam:
This is my first post, I'm not a pro at roms/kernel/etc, but I've learned something over the years, I guess.

Well, let's do it. This process is the same as reviving a bricked phone. This is an official rom so you don't need to have the bootloader unlocked, unless obviously you want to be rooted. As you know, we only need four things, the motorola universal drivers installed, adb and flashboot drivers, platform tools and the official android 11 Stock Rom (Retail Version), I don't know if it works with the dual sim version but this is easy peasy lemon squeezy.

Tools:

-Motorola drivers: https://motorola-global-portal.custhelp.com/app/answers/prod_answer_detail/a_id/88481/

-Adb and fastboot drivers: https://drive.google.com/file/d/0B0...WkE/view?resourcekey=0-64AHOI-cvO3EHX6xZiOXQg

-Platform Tools: https://developer.android.com/studio/releases/platform-tools

-Stock Rom: https://mirrors.lolinet.com/firmware/moto/odessa/official/RETAIL/

Instructions:

First, install the drivers, then unzip the platform tools rar, and with the stock rom downloaded, you just have to unzip it and transfer all the files to the platform tools folder, it doesn't matter that all the files get out of order, just make sure that all the files both as the platform tools and stock rom are in the same folder.

Now, make sure that your phone is at least 90%, if you want to have a clean experience, I recommend to do a factory reset, if you don't want that, don't do it, it still works, although it takes a little longer to install, lmao.

Second, turn off your phone and enter to fastboot mode, once you have installed all the drivers, just connect your phone to the PC, it should recognize it. To make sure, open a terminal and type the command "fastboot devices", and it should respond with a code and with the word 'fastboot' next to it. With that we know that the PC recognizes the device.

Third, close the terminal and now open a power shell or cmd with administrator permissions, and inside the terminal enter into the folder where the platform tools and stock rom files are. How to do it? (if you don't already know) There are two ways, you open a terminal directly from the folder, or inside cmd or power shell you write [cd 'insert folder address'] simple as that, hit enter, and then just copy and paste these commands and hit enter:

fastboot oem fb_mode_set
fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img
fastboot flash vbmeta vbmeta.img
fastboot flash radio radio.img
fastboot flash bluetooth BTFM.bin
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash dtbo dtbo.img
fastboot flash recovery recovery.img
fastboot flash super super.img_sparsechunk.0
fastboot flash super super.img_sparsechunk.1
fastboot flash super super.img_sparsechunk.2
fastboot flash super super.img_sparsechunk.3
fastboot flash super super.img_sparsechunk.4
fastboot flash super super.img_sparsechunk.5
fastboot flash super super.img_sparsechunk.6
fastboot flash super super.img_sparsechunk.7
fastboot flash super super.img_sparsechunk.8
fastboot flash dsp dspso.bin
fastboot flash erase userdata
fastboot flash erase ddr
fastboot oem fb_mode_clear

Let everything proceed, there should be no errors or anything like that if you have all your drivers installed correctly. After it finishes processing, reboot the phone and you already have Android 11 installed, then just configured your phone.

What's working (for me) lmaooo:

Everything, this rom seems to be optimized for all moto G9 Plus devices in general, although in system information it says that it is from Brazil, which I heard about it has many bugs and lag.

What's not working:

I don't know, don't tell me because I don't know anything about rom development, lmfao.

Just kidding, it has certain bugs. The default launcher for some reason has a large empty space where the Google widget should be, it's very annoying, but since I use the Nova Launcher, I could easily forget it.

The other thing would be is that sometimes the navigation bar gets bugged, very seldom but it happens, and it gets stuck vertically when you're using horizontal content, you just fix it using the auto-rotate to detect its position, or you use the gesture of recent apps in the position in which you are using it, it has only happened to me in some games like Fortnite or watching a video, very few times, but as I said, it happens from time to time.

Those are the only problems I've had, otherwise I feel it more fluid and faster than the default Android I had, even more, before the battery lasted 8 to 10 hours but now it can last 12 hours of constant use in basic applications such as social networks and media content and I have installed many applications that are open in the background all day long. So that's a pretty good thing.

Now I will teach you how to install root with Magisk.

I hope you have not yet deleted any files from the platform or the stock rom, because we will only need one file, boot.img, the key to everything.

So, once your mobile is configured, (obviously you must have the bootloader unlocked for this), just in case it turned on USB debugging, I don't know, I'm not sure, lmao, but I did it with USB debugging turned on. Copy the boot.img file to the phone memory and install the Magisk Manager apk, open the app and then go to install magisk, it will take you to the section where it says if you want to install magisk by patching a boot file, you click there and then select the boot.img file, it will patch it and then it will download you an img file that you'll gonna found in the download folder. You're going to copy that file and take it to the platform folder in the PC, then you're going to rename it as boot.img, do not replace the original file, just remove the original file from that folder and leave the renamed there.

Now turn off the mobile and enter to fastboot mode, as in the other process, open a terminal with the address of the folder, and put this command:

fastboot flash boot boot.img

And then reboot the system, go to the Magisk Manager and it should show you that you have root installed.

Congratulations, you are now rooted on your new Android 11 system. I hope this tutorial has been helpful to you, and that you have been able to understand me, since english is not my native language, that was it, thank you!
