[Help]firmware version confusion for downgrading from N soak to MM stock.

i am using moto g4 plus indian version ( XT1643 ) want downgrade from N soak test ( NPJ25.75-2) to Stock MM , so that i can upgrade to latest official N build.
i searched various threads for the same but , all of them confused me on the firmware version for xt1643.
i am not sure which firmware version to flash as, flashing wrong firmware can lead to serious problems .
can someone please tell me what is the firmware version for xt1643.
like is it MPJ24.139-63 or MPJ24.139-16 or something else ( i just gave these examples for the sake of clarity of what i want to know)
thanks

Keep in mind that don't downgrade gpt and bootloader.

Fastboot Files

Can anyone provide me Moto X Style 1572 Asia DS fastboot files for Nougat firmware??
I accidentally installed 6.0.1 ES verison and now i am unable to flash 6.0 ASIA DS firmware.
In India Motorola didnt updated XT1572 to 6.0.1

Sorry to hear that but unfortunately the Motorola's official firmware center link has been removed all you need to do is wait for nougat firmware aka (fastboot files)
You can't even downgrade as it'll throw pre valid errors over you
And btw der was no 6.0.1 for Retasis_ds

Thanks

as Firmware.Center is down, Use these links
6.0.1 with september 2016 security, (download might be slow)
http://www.filefactory.com/file/66c...S24.107-58-5_cid7_subsidy-DEFAULT_CFC.xml.zip
6.0 with september 2016 security,
https://mirrors.lolinet.com/firmwar...HS24.49-18-8_cid7_subsidy-DEFAULT_CFC.xml.zip
once you boot up, both will give you the december security ota....
You can relock the device if the EU version number that you flashed is less than these firmwares. if you get prevalidation error then skip fastboot oem lock and flash gpt commands

Thanks Sir.

Unfortunately if your on Oreo you won't be able to downgrade to nougat. Depending on the bootloader version number you can not even downgrade to an early version of Oreo either.
Bootloader version number is the 5th number from the right of the file name that you downloaded from sammobile. Binary 2 device 4 is telling you that your current bootloader version is 4 and you are trying to flash a version with bootloader ver 2.
Eg: G950FXXU4CRKG is a name of a file that you would download from sammobile. The number 4 ( 5th from right ) is the bootloader version number. So you can only flash with a BL 4 or higher and not lower ( ie: 3,2 or 1 )

Flash the full Oreo firmware without the BL tab, then you will be downgrading to Oreo but you will still keep the Pie bootloader.
Also if you do want to downgrade the bootloader I found this thread: https://forum.xda-developers.com/galaxy-s8/how-to/guide-skipping-kg-prenormal-oneui-t3911862/amp/

No, I have not tried it but I thought it might work. Try downgrading the bootloader via this method https://forum.xda-developers.com/galaxy-s8/how-to/guide-skipping-kg-prenormal-oneui-t3911862
I think you can also get heimdall on Windows
Edit: I found the heimdall download page here: https://glassechidna.com.au/heimdall/
If that doesn't work I also found this thread about downgrading the bootloader with combo firmware: https://forum.xda-developers.com/galaxy-s8/help/method-to-downgrade-galaxy-s8-to-oreo-t3946240/amp/ You just have to find a combo firmware with the same binary version as your current firmware.
Downgrading the bootloader is really hard on Samsung devices if possible at all

Your device is on a bit 7 bootloader. The firmware you are trying to flash is a revision 3. You cannot downgrade your revision. 5th digit from far right end in firmware is your software revision

hi i have a sm-g955f
with g955fxxs7dta6 base band
can i downgrade from android 9 to android 8?
thanks

Same as post as above yours check all the Android 8 firmwares if they are the same bit number as Android 9 then yes. If not. No

so in my case I have to find a custom android 8 rom with bit 7?

and if I put a custom rom with a lower rev bit can I downgrade?
having rooted and having twrp?

if it has knox, most likely not

[QUOTE = "avipars, post: 84174127, member: 7551187"]
se ha knox, molto probabilmente no
[/CITAZIONE]
knox is 0x1 therefore no guarantee

I don't think you can

sims were getting detected but were showing no Service.

I recently Flashed stock rom NPJS25.93-14-18 , After flashing i got an update off ~40mb,Once the update was complete Both the sims were getting detected but were showing no Service.
Also my baseband was changed. is there any way i can revert back to the indian baseband ?
Device : XT1643
Bootloader status : unlocked
