    Jelly Pro Stock Boot, Stock Recovery & TWRP

    I take ZERO credit for any of this. I just received my Jelly Pro and am reposting information I found useful to get TWRP & root. I take no responsibility if you bork your device.

    Enable Developer Options (Settings,About phone,click Build number until you see 'You are now a developer')

    Go back to Settings, scroll down to the bottom and you'll see a new ‘Developer Options’ entry right above ‘About phone’

    Enable OEM unlocking
    Enable USB debugging
    I also disable animations, just a preference, but not necessary

    Make sure your usb drivers and adb/fastboot is set up on your computer

    From terminal:
    adb reboot bootloader
    fastboot oem unlock

    fastboot flash recovery twrp_jelly_pro.img
    fastboot reboot

    (hold volume-up and power to go into recovery)
    ****if something went wrong and you get a "command not found" message, click volume-up & power a few times to go into stock recovery, then do a factory reset and try again)

    ****when going into twrp, DO NOT allow modifications

    In TWRP, go to ADB Sideload and swipe to start
    From term: adb sideload
    Back in TWRP, go ahead and reboot

    should have TWRP recovery and root

    hopefully we'll start seeing some ROM's for this little guy....

    1. Stock boot:!UbZASJTI!weBJa4uu9DGoJglpqHQMf3WE6hHplgqPJ7O5UBjDJAQ
    2. Stock Recovery:!9SoTVDbY!dZI7XYYSqwPaq2542lQFh5NNXbrA0KTqDCzy-46Dsd0
    3. Twrp recovery:!0WICAZwD!cUSG82h1SnuI_cDHWg9ir2w5xb0T-fAl9MrWeClnRBs
    4. Latest Supersu flashable zip:

    (original post:
    Here you can find the shared files from Unihertz in order to flash to stock using MTK SP Tool and then update to latest version
    UniHertz JellyPro

    <_Root_and_Custom_Recovery_> :good:​

    1. Initial setup phone (Input wifi if no mobile data. Google not required for now)
    2. Settings>System>About Phone>Wireless Updates>Install Update (Important to do this before modifying boot/recovery image)
    3. Developer Options > Unlock OEM
    4. Developer Options> USB Debugging Enabled
    5. Connect phone to PC with USB cable
    6. Use a CMD prompt to run ADB command as follows:
    7. Code:
      ADB Reboot Bootloader

      Once in bootloader, type:
    8. Code:
      Fastboot OEM Unlock
    9. Press Volume Up to confirm

      Fastboot flash recovery [URL=""]TWRPrecovery.img[/URL]
    10. After it flashes, hold Volume Up and Power, and type:

      Fastboot reboot
    11. Hold Volume up and power until it boots to TWRP recovery
      NOTE: Phone will try to restore recovery image on boot. You must hold the buttons after flashing to directly enter TWRP. If you fail to do so, you may have to go back to step 5.
      Pick Read Only!
    12. Flash Magisk ZIP to acquire root
    13. Back to TWRP main menu
    14. Wipe>Format Data (This will disable encryption on the data partition)

      <_HOW_TO_FIX_BRICK_> :good:​

      :(If you brick (no fastboot), use this tool

      And this rom

      With these drivers

      On a Windows 8 or lower machine (because of unsigned drivers)

      You will need to follow these instructions to reflash the phone.

    Note: When reflashing with SP MDT, you should turn the phone off before plugging it into the PC. This is the only way to flash it over vcom port***
