Those additional details are informative. First a disclaimer, I don't have the experience to interpret all the details of getvar or other flashing related logging, so I'm applying other troubleshooting experience to a logical testing framework (and perhaps someone else can provide "real" answers based on your info

).
OK, you've gone back and forth between stock and custom before (so, unlocked bootloader) then after flash of wrong version = boom, and although RSA/LMSA can see, download and attempt to install, there is the reported error. Ideas:
- Wait for someone who has actually experienced this or has the knowledge to get into deeper troubleshooting. IE maybe this can be fixed by some command that changes the region or something like that
- Check the LMSA download folder to see if all the requisite material is there and that it matches the device. It may also be helpful to compare file names and total size with what is available at
https://mirrors.lolinet.com/firmware/motorola/.
- Poke around in fastboot to see if there are any odd or blank values for "modem, "base-band", etc. (this is more for potential later troubleshooting and might be in getvar)
- Try to boot to TWRP from a computer via fastboot poke around in there..
- Can any ROM be flashed or restored to the device? If yes then maybe LMSA doesn't like a region setting or partition arangement.
- If you've got access to a Windows 7 computer you might be able to try restore to stock using an older utility (RSDLite) which can flash the material from lolinet (at least up to Moto X in my experience).
Thank you, so much for your reply, i appreciate it alot! im hoping this will get cracked or at least put to rest so im not trying to do something impossible.
I wasnt able to find a twrp that matched my device, so i tried the first twrp that i could find that seemed to work with android 12 and gave it a tried to boot but get this :
.\mfastboot boot twrp.img
downloading 'boot.img'...
OKAY [ 0.898s]
booting...
(bootloader) Fastboot boot command is not available in locked device
FAILED (remote failure)
I tried to unlock the bootloader but was met with this message:
PS C:\mfastboot> ./mfastboot oem unlock
...
(bootloader) Check 'OEM unlocking' in Android Settings > Developer
(bootloader) Options
FAILED (remote failure)
............
I The firmware that LMSA downloads is the same size as the one on
https://mirrors.lolinet.com/firmware/motorola/. And even replacing the firmware that LMSA downloaded with the one on the website, it wont flash and give me the same message about going to a customer center.
.........
No other roms can be flashed at least the ones I've tried all from the loli website., and no windows 7 to use either :/ just my luck.
Something i did find odd was that every time i would connect to LSMA and looked at the BOOTLOADER LOGS it would constantly spit out the following commands on its own:
cmd: getvar : slot-count
cmd: getvar : all
cmd: getvar : slot-count
cmd: oem hw dualism
cmd: getvar : slot-count
cmd: getvar : dualsim
cmd: getvar : slot-count
cmd: oem hw dualism
cmd: getvar : slot-count
cmd: getvar : dualsim
when i try to run these same commands i get the following:
slot-count: 2
(bootloader) dualsim: false
and then
(bootloader) dualsim: not found
getvar:dualsim FAILED (remote failure)
then when checking online on
Check IMEI Number and find out hidden info. Check hardware specification, warranty or BLACKLIST status and more for FREE. Over 110 mln checked IMEI's in our database.
www.imei.info
it states that my phone is a DUAL SIM, which is not true, it is only a one sim phone from what i can tell. So it has me thinking if LSMA is looking for a dual sim when its not. But i didn't have this problem in the past using LSMA for some reason now it wont let me flash its recommended firmware.
It really has me puzzled, I haven't been able to flash,, format, or boot anything. The commands run but it just returns to "no valid operating system could be found the device will not boot" OS Fingerprint: 0xC2224571" screen. Im open to any more suggestions and in the mean time keep poking around until i find something that gives me some sign of life. I hope someone out there may be able to help.
*Edit: I tried to flash the firmware myself but wasn't able to, this is what returned:
./fastboot flash partition gpt.bin

I then decided to compare the bootloader files and it seems that the LSMA bootloader file is different than the one on the phone.
BOOTLOADER ON PHONE
(bootloader) version-bootloader: MBM-3.0-uefi-51fb89de16b-221130
BOOTLOADER ON LSMA FILE
MBM Version: MBM-3.0-uefi-ff43dd709-221130
Could this be the issue? Do i need to download each loli firmware file individually to find the matching bootloader file to be able to flash it?
*Edit 2: I stumbled upon another post, in which the user apparently has a very similar bootloader file to mine. Just wondering if this is anything i should be looking into. This is the post im speaking of:
Hello everybody, I can't find correct subforum for Moto G51. Hope I can get some help here. I have softbricked my phone by doing two mistakes: 1) Trying to flash the software for XT2171-2 on my XT2171-3 2) Forgetting to switch on "OEM...
