    Does anyone know how I can get the stock ROM/ firmware (Android 4.1.2) for a ZTE Sonata 4g (Z740g) on Cricket?
    I flashed a stock rooted ROM, only to discover it was for AT&T. Then the Nandroid backup was gone.
    I really would appreciate any help with my search.

    If you are looking to restore your Z740G the ZTE Sonata from Cricket then this is how I did it.

    I rooted it and installed a rom for the Z740 ATT radiant model and had issues with the mic being too low and speaker was low during calls.

    Anyway, to restore download these 3 files.

    1. root it with the 'android_root' one click rooting file. Follow instructions (dont worry about errors, it still worked for me)
    2. connect your phone with usb debugging turned ON (let it install drivers)
    3. unzip clockworkmod.zip and copy the folder 'clockworkmod' to the root of the SD card you want to use. (it is almost 600mb of space make sure you have enough space first)
    4. unzip z740_cwm_tch and open the file 'install_z740_cwm_tch.bat' (follow on screen instructions)
    5. Once clockwork mod boots up select backup/restore then backup from sdcard or sdcard1 for external if you put it there
    6. it will show you the 1970.... folder and select it then it will restore the stock recovery to the phone.
    7. once it is finished reboot phone and do a factory reset from the settings menu.
