**It's really simple- once you get familiar with this process, you can do it fairly quickly.
**Take the time to read through and get everything set up and you'll be set for future updates.
**No begging the internet for flashable zips.
So my situation is i'm running stock, bootloader unlocked, rooted, and xposed on my US XT1540 2GB Moto G. I went through the process this morning of updating to the new 23.46.4 update. Thought I'd share what I did for anyone out there wanting to update with questions ; hopefully some can be answered here. I'm familiar with flashing firmware files from my previous Moto X's '13 & '14 so trust me it's not a big deal to flash back stock firmware to update. This process should be applicable to any variant of the Moto G and and to any future updates as well, not just the one mentioned here as of 09/19/15. Just be mindful of your phone's version and use the appropriate firmware.
- First, make sure everything worth keeping is on your microSD. Flashing stock firmware will wipe your phones internal memory so pictures, music, downloads, SMS, etc need to migrate. Also make sure you have SuperSU and Xposed on your microSD for re-installation. This might be obvious for some and you might have everything going to your microSD (sdcard1, EXTsdcard) already, but one thing you might miss is Titanium Backup...
- Save apps in Titanium to microSD: Menu>Preferences>Backup folder location>Click to change>Ext. SD card>Create a new folder>Use current folder
- Nandroid in TWRP to microSD: toward the bottom click on "Storage: Internal storage" and choose "Micro SDcard"
If you're super smart, after making that backup you'll copy that to your pc.
- Get the most recent firmware for your device from lost101's firmware thread (thank him threads like this are so helpful)- http://forum.xda-developers.com/2015...mages-t3169639
- Download and install the drivers for you phone, I believe the generic android driver will work but you can also get them from Motorola Device Manager: https://motorola-global-portal.custh...ail/a_id/88481
- Download mini-sdk.zip, attached to the the bottom of this post. Useful light weight sdk containing adb & fastboot which should cover all your flashing needs. If you're not developing apps, full blown android sdk is bloatware
3) SETTING UP ADB/FASTBOOT
- Enable USB debugging in Developer options
- Extract mini-sdk.zip to a folder. Extract and add the contents of your firmware to that folder.
- Open a cmd prompt on the mini-sdk folder (shift + right click, "Open Command Window Here")
- Let's verify that adb sees the device:
- Should see "XXserial#XX device". If you get "offline", be sure to check your phone for the adb authorization dialog.
- We're ready to flash firmware so reboot into fastboot:
adb reboot bootloader
4) STOCK FIRMWARE INSTALLATION
- Once phone is in fastboot, enter the following commands in the cmd prompt (open on the mini-sdk folder containing the firmware files) one at a time. Let the current flash command finish before entering the next, especially at the img_sparsechunck steps because they take a 10-15 sec each. Also make sure all of the filenames match what you have; substitute accordingly.
fastboot flash partition gpt.bin fastboot flash bootloader bootloader.img fastboot flash logo logo.bin fastboot flash boot boot.img fastboot flash recovery recovery.img fastboot flash system system.img_sparsechunk.0 fastboot flash system system.img_sparsechunk.1 fastboot flash system system.img_sparsechunk.2 fastboot flash system system.img_sparsechunk.3 fastboot flash system system.img_sparsechunk.4 fastboot flash system system.img_sparsechunk.5 fastboot flash modem NON-HLOS.bin fastboot erase modemst1 fastboot erase modemst2 fastboot flash fsg fsg.mbn fastboot erase cache fastboot erase userdata fastboot reboot
- When you reboot, if you don't get prompted for update check for it- About phone>System updates
- Download & install update
- When update is finished and phone boots back up, enable Android debugging in developer options.
6) FLASH BACK TWRP/ROOT/XPOSED
- Place TWRP img file in mini-sdk folder. Boot back into fastboot and flash TWRP.
adb reboot bootloader
fastboot flash recovery twrp-osprey-2.8.7-test1.img
- Vol up/down in bootloader to boot recovery.
- Once in recovery flash Supersu & xposed (optional of course) from your microSD and reboot.
- Install Titanium from play store, go back into preferences and point to backup folder on the microSD and restore apps.
When xposed and modules are reinstalled through Titanium, you will need to reboot to enable. After that you'll need to tweak your preferences in system options like notifications or display, but any settings in modules (like gravity box) will be restored as long as you backed up app+data in TB. Easier than a custom rom clean flash in that aspect.
So that's it, with that you should be back up and running. Let me know if I missed some steps or if you have questions about the process.
BTW, Installing xposed from scratch for those confused on what files to do what with: http://forum.xda-developers.com/show....php?t=3034811
- Flash this one in recovery: xposed-v74-sdk22-arm.zip (or most current)
- Install this apk after you reboot: XposedInstaller_3.0_alpha4.apk (or most current)
