[X Style (Pure) Q&A, Help & Troubleshooting] Ohmster:
*NOTE: I tried to update my XT1575 Moto-X Pure Edition from a file on this page and it was a disaster! I now have the OTA visible on my phone, see screenshot, that keeps popping up. My phone is currently rooted, unlocked, and has TWRP installed, all courtesy of WinDroid tool. Windroid was painless, easy, and got the job done pretty quickly. Now that I can take the OTA update, is there an instruction page somewhere showing how to take the upgrade and keep root and recovery TWRP? That is the gist of what I really need.

I have a new Motorola Moto-X Pure Edition, rooted and TWRP with WinDroid app from Windows. This made it incredibly easy to unlock bootloader, install TWRPm and root. I am very happy with this system and some Xposed modules. I heard all the hoopla about the new Marshmallow rollout but did not have it offered to me on this phone. So, I did it manually from this page:

Stock/Rooted/Debloated X1575 6.0 MPH24.49-18

So much to choose from so I downloaded the moto_x_pure_edition_rooted_x1575_mph24.49-18_v1-deodexed.zip and flashed it in TWRP, after making a nandroid backup in TWRP. Everything seemed to work fine but I had problems after problems. My 32 GB ext-sdcard "vanished" and the system insisted that I reformat the card as "Portable" or "Permanent". I chose portable. I could not get Xposed working properly. My password manager would not work, when I updated from the play store, I got the message that all Android 6 apps now require a password at first run. Huh? What password? None of the passwords I have for the password managers would open the app.

Before losing 30+ GB of data on my ext-sdcard, I copied it to PC, then when complete I put it back in the phone, allowed the format as portable, then pulled the card and restored my stuff. Nothing was working right and it was pretty scary as this is my only phone. I restored the TWRP backup and had some settling in issues, but it worked, all but for WiFi. I could not turn it on! Like a spring on the switch, the moment you switched on WiFi, it snapped right back to the OFF position. No more WiFi. A friend sent me a stock recovery zip file, CLARK_RETUS_5.1.1_LPH23.116-18_cid9_subsidy-DEFAULT_CFC.xml_SHAWN5162.zip.

This file, once unzipped, will flash the entire phone back to stock. He send me a small modem-flash.bat file because he thinks that I have an Android 6 radio in an Android 5 device. After running the flash-modem.bat, I got my WiFi back.

flash-modem.bat

@ECHO Off
@Echo Test
C:\adt-bundle-windows-x86_64-20140702\sdk\platform-tools\adb reboot bootloader
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
.fastboot reboot

Now I am really, really gun shy. I now have the dreaded update message on my phone, see screenshot. I found some good instructions here:

[GUIDE] Unlock/Root/Flash for Moto X Style/Pure

Are these instructions safe if I take the OTA update?

What preparations should be made prior to taking OTA aside from a TWRP backup?

Must I really format my ext-sdcard to use Marshmallow?

What other kind of weird things will happen?

Thank you so much, scared "sheetless in Florida" :eek:
