[X Style (Pure) General] cmahendra:
Latest Android 6.0 Build No. MPSH24.49.18-4 for Moto X Style
​

Scenario:

While experimenting various stock roms for my Indian Version Moto X Style 1572, I flashed 1575 on my phone. Network did not work. But without trying to fix all the issues , I stepped back and flashed back to Indian Retail Version of Stock Rom XT1572_CLARK_RETASIA_DS_6.0_MPH24.49-18_cid7_subsidy-DEFAULT_CFC.xml.zip from this page. Everything worked but my Bluetooth stopped working. Then tried almost all custom roms and even cyanogen but BT never worked.

So now I was left for few days with BlueTooth issues in phone. Then after taking hints from various threads I managed to unbrick my phone to get latest stock build and May 2016 Android Secutity Patch Level

In short this guide unbricks Indian Moto X Style perfectly to resolve BlueTooth issues / IMEI Loss / other network related issues by flashing latest stock to Android 6.0

Advantages:

1) An important thing to remember, that above Indian stock rom, you will get Android Security Patch Level dated 1-February-2016. But I with files linked by me in this guide (Brazil Rom) so you will get Android Security Patch dated 1-May-2016 with more security :D

2) The rom is 3 months latest than Indian Stock and build is MPSH24.49.18-4.

3) Initial free space of usable internal memory is upto 75% out of 10GB, which is much higher than Indian Stock which gives only 50% usable space.

Resolution:

Taking idea from this EU (European) Single Sim version I decided to try BRAZIL's latest Dual Sim stock rom and then flash modem+baseband, and VOILA!! Everything Worked perfectly! No network and bluetooth issue anymore. :D

UNBRICKING STEPS:

So I thought to put these steps here following easy steps.

1) Download BRAZIL's latest official Dual Sim MM 6.0 firmware - MPHS 24.49-18-4 - RETLA-DS-Brazil (May) from here. Extract all files from rar file into new folder on desktop of pc.

2) Also Download Indian Baseband or Modem file called fsg.mbn (DOWNLOAD and extract "fsg.mbn" file in above new folder on your desktop by replacing over brazillian version of fsg.mbn

3) Start phone in Bootloader Mode (power off phone. Then press VolumeDown Key and Power Key both together to start phone in bootloader mode)

and then connect phone to pc with usb cable.

4) Now open command prompt windows on your pc and from the new folder, execute batch file named "Instalador.bat" at command prompt. Wait until all commands are executed which flashes all partition image files one by one. Press any key when prompted on screen to go ahead and wait until it finishes. When done phone will automatically restart. Now you can disconnect USB cable from phone.

Phone will start normally but WITH FULL NETWORK, Wifi and BLUETOOTH all working just fine.

5) Optional (rooting): First enable debugging mode in Settings >> Developer Mode. Restart phone in bootloader mode and connect to pc and from windows command prompt execute following commands to flash latest TWRP recovery file. (DOWNLOAD TWRP).

Now start phone in TWRP RECOVERY mode and flash SuperSU flashable zip (DOWNLOAD)

You are done! Network will start showing properly and strongly in both sims Bluetooth also works fine as it should work.

===================================

*Note: 5th step is optional if you do not want to ROOT your phone.
