I have found the stock ROM, I bricked my device in the rooting process, and am unable to flash the complete stock image, because the device reports "unable to flash bootloader on unlocked device"

Hi, because you should not flash bootloader.
you can try those 2 solutions:
the fast one, it should work. The flashall command flash every.img files he find in the fastboot directory. So try to remove the bootlader.img and execute the flashall command.
the manual one (longer one):
Put only the recovery.img, boot.img, and the system.img files ( you should have something like 13 , named "systemchunk0/12.img") in your fastboot directory and flash with fastboot ( the command is always the same: fastboot flash recovery recovery.img, fastboot flash boot boot.img, and for every single part of system.img you should flash like "fastboot flash systemchunk0(until 12).img " so you flash flash 13 times the system with avery 13 parts .
Sorry for my english i hope you solved that

I did try this, but I still have no signal because the modem file is part of the bootloader, and no modem means no mobile signal

Ah ok i didnt understand that you have this modem issue. I don't kno how to help you...you phone is bricked so you can test few solutions without more risks .
before flash the original recovery , boot and system by fastboot, you can try to install TWRP again and flash only the bootloader from TWRP (should support .zip and .img files). Then you turn the phone in fastboot mode and flash other stuff .

Factory Images & Systemless Mode
Q: I messed up help me?!
So you screwed up and didn't follow Rule Number One in the IT-Handbook?
Which is: Always create a backup before working on a system?
Download the Factory State Images. Which are all flashable with fastboot: https://goo.gl/JTCwKj
Place the files you want replaced into the "Minimal ADB & Fastboot" installation directory and start it's shell:
If you want to flash back the stock image. Simply run:
Code:
Code:
fastboot flashall
You can also replace all partitions if required.

Thanks, I was on P2a42_S038...TMO (T-Mobile, checking OTA update = you are using latest software) flashed this P2a42_S048_ and got OTA info to download latest ROM P2a42_S062_170117_ROW (103MB) :good:

Is there an alternative download link? What is Mega? I want to avoid these third party download utility if I can...
I put the following into a BAT file and placed it into ADB / Fastboot directory:
Code:
fastboot flash partition gpt_both0.bin
fastboot flash bootloader bootloader.img
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash dsp adspso.bin
fastboot flash system systemchunk0.img
fastboot flash system systemchunk1.img
fastboot flash system systemchunk2.img
fastboot flash system systemchunk3.img
fastboot flash system systemchunk4.img
fastboot flash system systemchunk5.img
fastboot flash system systemchunk6.img
fastboot flash system systemchunk7.img
fastboot flash system systemchunk8.img
fastboot flash system systemchunk9.img
fastboot flash system systemchunk10.img
fastboot flash system systemchunk11.img
fastboot flash system systemchunk12.img
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
fastboot erase cache
fastboot erase userdata
fastboot erase customize
fastboot erase clogo
pause
Extract all the files listed in the BAT file or simply extract the entire archive to ADB / Fastboot and launch the BAT file.
Does this work?? @Undesirable
the above post
Oh yeah, it unbricked me and put me back to stock so I could get OTA updates for Nougat. You need the archive posted earlier in the thread though.
@Undesirable Nice and elegant solution man! Typing all this stuff was so annoying.
For those who need an alternative download source, I offer this magnet link:
Code:
magnet:?xt=urn:btih:ef05ea3af4da8a0cbb137c10621942f3ae16d46f&dn=P2a42_S048_161111_ROW_fastboot.7z
It's slow unless lots of people help to seed it.
Is it possible to flash this firmware 2a42_S048_161111_ROW_fastboot.7z on the P2c72 with firmware build number: V3.5_1652_5.1342.1_ST_p2c72 ???
I bought this phone 4GB Ram/64GB from china, but I want to put the international firmware on it.
Thanks!

how can I replace my data partition? It's not getting formatted due to an encryption error
If fastboot erase userdata doesn't work, then use TWRP to change user data file system to EXT4 then change it back to F2FS again.
Need help...
I flashed back the stock ROM (due to encryption error in custom 7.0 ROM) using fastboot commands, but my SIGNAL WON'T WORK after I started d phone . I've tried reflashing the stock firmware (and also custom ROMs) but my phone won't detect the signal. "About phone" settings show unknown baseband and IMEI... how to get it back

I've flashed 'ROW' variant of stock ROM. Is there a different version for Indian variant?
First, I assume you know what root, fastboot, SafetyNet, bootloader, adb is ( SEARCH FIRST BEFORE DOING THESE STEPS! ) and you know the risks of rooting a device!
Me nor the XDA guys are responsible for bricked devices, nor any damage to you and/or your device.
So, after that, let's dive into the steps of rooting it
First of all is to download your stock android image ( in case something goes wrong plus the boot.img needed for this process )
You can download your stock image the way you want, you can use lolinet etc, just make sure it matches your device!
So, open the image you downloaded, extract the boot.img file and put it on the phone's internal memory, then download Magisk Manager ( I personally used GitHub to download.... ) and open it.
Now, select 'Install' ( the one that says Magisk, not the manager ), go to 'Select and Patch a file'
Navigate and select your boot.img, then wait for it to complete, after that, you'll see a file in the Download folder on the phone called 'magisk_patched.img' grab this file and put it on the computer.
The next step is that you'll need to unlock your bootloader ( I'll not cover how to do that here, but a quick search on ' how to unlock Motorola bootloader' should help ), but be aware that it will format your phone ( you'll lose any saved data, so pay attention! )
After, put the phone in fastboot mode again ( vol minus + power button ), then on the terminal window you're using fastboot, run this command:
fastboot boot magisk_patched.img
( I assume you put the magisk_patched in the same folder you're running fastboot ( Windows case ) )
REMEMBER TO TEST EVERYTHING ON YOUR DEVICE IN THIS PART BEFORE CONTINUING!!!!!
IF YOUR PHONE DIDN'T BOOT OR BOOTED BUT WITH MALFUNCTION STOP NOW AND REBOOT IT, MAYBE YOUR STOCKROM WASN'T CORRECT OR SOMETHING ELSE...
After that your device will normally boot, install Magisk Manager and check if it "says" installed and displays the version.
If so and your device runs fine, reboot again to fastboot then run on the terminal window:
fastboot flash boot magisk_patched.img
This will make the root persistent after reboots
Now as you expected, you're rooted
A bonus tip:
Safetynet will fail! To fix that, open Magisk Manager, then go to it's settings, then tap to enable "MagiskHide" and then tap "Hide Magisk Manager" type a new name for the Manager and boom, that's it, now SafetyNet will work ( In my case it did hehe )
I'm new to English, learning alone, so any mistyping etc tell me and I'll fix it
Also I'm new to XDA too hihi
Thanks a lot for sharing your experience!
Has there been anyone else who managed to root this device?
I really want to buy one but first I want to make sure I will be able to root it from day 1. I don't like to use an unrooted phone
I bought my device last Black Friday and rooted it this week with this guide.
I’ve downloaded my boot.img from Lolinet and googled how to unlock a bootloader of a Moto phone.
I’ve also enabled oem unlock in developer settings.
It’s not so difficult.
The bonus tip from the OP is very helpful. Only rename Magisk is not enough. Also hide the manager to pass the safetynet test.

Hi, I root the G9+ with your guide and now it's rooted, thank you for post it. I want to change te system fonts, I have some visual impediments and I need a fonts with more contrast and bold. I try with Fontster, HiFonts, Zfonts, and many more. I grant root privileges to these via MagiskManager, but without any success. It's normal that? any idea why? The rootchecher confirm that the phone it's rooted. Please can help me? Thank you and please excuse my poor english

I think u'll need to port your custom fonts as Magisk Modules, since you can't change system files directly ( even with root ).
Hi, I'm new to rooting the phone, I managed to unlock the bootloader, I did everything as in the description except the last step because the fastboot boot magisk_patched.img command did not work. So I copied the magisk file to the adb folder and typed: fastboot flash boot C: \ adb \ magisk_patched_INTjS.img. My phone touchscreen has stopped working. I'm very worried. Is it possible that I used the wrong stock image version or did I do it wrong? Now I wish the phone would just work

So maybe your stock was wrong, if ' fastboot boot magisk_patched.img ' failed then u can't force ( fastboot flash ) the installation since it'll probably cause problems...
I suggest you try to download your stock rom and re-flash the boot partition, if no lucky, try using ' Lenovo rescue and smart assistant ' and hope it works again...

Yes, I tried to enter this command but it said that it cannot find the file magisk. Tomorrow I will try to install the stock rom with RSD Lite if that's the right decision, with the help of this website: https://www.androidinfotech.com/moto-g9-plus-odessa-android-10/. If that doesn't help, I will have to give it to repaired because I won't be able to handle it myself.

Room that I will download should I unpack to adb folder or where? Is it safe to install it yourself or is it better to go to a local phone repairer? It may be hard to find someone who knows what to do.

Yeah, as I said, u need to unpack it to the folder where you see the ' fastboot.exe ' file, and then copy all the spoiler commands I sent, put the phone in fastboot mode, and open the cmd in the folder where fastboot.exe and your extracted rom is, then paste and run the spoiler commands and you're good to go, remember that it'll take a while since it'll re-flash all your system.

No prob, we're all learning, and all you need to fix a device that doesn't boot, is an unlocked bootloader, since u can re-flash, I did this on a few devices ( moto x4 ; moto G5s ; moto g9+ ) and succeeded on repairing those...
PS: I know some of the linux thing, but I have no experience in building an Android ROM. Any suggestion and discussion are welcomed
1. Make sure you are on the CN ROM. If not, revert to it.
2. On your CN ROM with magisk/root access, run
Code:
dd if=/dev/block/mapper/vendor_a of=/sdcard/vendor.img
this is to dump the vendor partition where the NFC drivers locate. use vendor_b instead if you are in the b_slot
3. Copy your dumped vendor.img from your phone to your computer with fastboot env.
4. Now flash your internation ROM: AP only
5. run
Code:
fastboot reboot fastboot
get your phone into fastbootd
6.
Code:
fastboot erase vendor_a
fastboot flash vendor_a <path of your vendor.img dumped from CN ROM>
7. reboot to fastboot, run fastboot erase userdata in case the userdata is encrypted
8. restart your phone
Ehh it works, thanks brother!

Is it possible to use this method to change touchscreen drivers? Do you know where it is stored at?
I was having a weird touch screen problem with virtual buttons with an international modified Rom and this touchscreen problem was not present on Chinese stock Rom...

this is to dump the vendor partition where the NFC drivers locate. use vendor_b instead if you are in the b_slot
3. Copy your dumped vendor.img from your phone to your computer with fastboot env.
4. Now flash your internation ROM: AP only
5. run
Code:
fastboot reboot fastboot
get your phone into fastbootd
6.
Code:
fastboot erase vendor_a
fastboot flash vendor_a <path of your vendor.img dumped from CN ROM>
7. reboot to fastboot, run fastboot erase userdata in case the userdata is encrypted
8. restart your phone
