If you bricked your device and you can't boot even to flashboot there is a solution from Unihertz:

If you see DA error, you need another rom like me (need Jelly Pro N, it's for MT6737T).
rom list: https://drive.google.com/drive/folders/0By1nhWOmuw2KdDhTUlFOZHpXQjg
flash app: https://drive.google.com/drive/folders/0By1nhWOmuw2KQ2lyNFIybnJIcEE
Both also in manual.

Hi, thanks for your reply. I know this locations, the tools and the instruction. I even have the tool in 2 diferent versions (v1.5.1 and v2). The problem is when i'm scanning for setting the ports my jelly wouldn't be recognized anymore. So on the tool in v1.5.1, because i startet the scan after bricking the jelly.

On the SPMultiPortFlashDownloadProject in v2 i didn't the scan so the port should be ok. But i can use any of my official roms and starting the port for Firmware upgrade ... nothing happens. The only thing i can hear is the connection of a usb device in windows. So it will be recognized at least as device. But the operation on the tool won't start!?

Down in the manual are instructions if it can't discover device. It helped me, I used app from the manual (my second link). Also you have to install USB drivers before trying to flash it.
Hope you'll be able to repair it, it took me about two or three hours to find everything and reflash it.

You can root via adb sideload using magisk or supersu zip. It works only with TWRP, original recovery says it's unsigned zip. Anyway TWRP isn't able to backup rom because of encrypted data partition. I wasn't able to decrypt it to get TWRP fully working.

Format data partition from twrp and everything will work, encryption will disappear [emoji6]

I wasn't able to format data partition. It probably works in android 7, but with latest rom it's blocked. Anyway I don't need TWRP, I need root because of Titanium Backup (restore apps data, remove bloatware) and that's it.

I have been looking to wire up a Jelly Pro inside a vehicle, but need to know if it can run without a battery. Does anyone know or can someone test if the phone operates without the battery in (but the power connected obviously)? It would be most appreciated!

Which version of firmware and version of twrp are you using at the moment? I am having problems when I install twrp after full wipe. It says 'no command' while booting in twrp recently installed… It boots normally to android (the last version for Jelly Pro [no N]). I don't know what can be causing this. I have used official twrp and the one that is posted here in first page.

Thanks in advance.

I'm stuck in an infinite "Orange State" boot loop, any way to get out of this? last command ran was "fastboot flash recovery twrp-3.2.3-2-jellypro.img" which gave me a "writing 'recovery'... OKAY"

Okay both of those links are pointless. the first one is a 404 and the second is a link back to this post. How can i get the fastboot drivers installed for the device? i can get adb to work but fastboot is just waiting for devices and ive installed all the drivers i could find even disabled driver verification in windows and android is still a yellow triangle

The problem is fastboot. You don't want to use 'fastboot' on this phone as it will cause bootloops. You need to use SP Flash tool (best choice) and have the correct scatter file. Orange state will only show up if you did an OEM unlock. I don't believe you even need to do the OEM unlock to root or install TWRP on this phone although some say you will but I've done it without unlocking and you can also relock it after rooting and TWRP. Make sure you have the right ROM for your phone. You need to know whether it is the M or T version.

    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 supersu-XXX.zip
    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: https://mega.nz/#!UbZASJTI!weBJa4uu9DGoJglpqHQMf3WE6hHplgqPJ7O5UBjDJAQ
    2. Stock Recovery: https://mega.nz/#!9SoTVDbY!dZI7XYYSqwPaq2542lQFh5NNXbrA0KTqDCzy-46Dsd0
    3. Twrp recovery: https://mega.nz/#!0WICAZwD!cUSG82h1SnuI_cDHWg9ir2w5xb0T-fAl9MrWeClnRBs

    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

      Then:
      Code:
      Fastboot flash recovery [URL="https://dl.twrp.me/jellypro/twrp-3.3.1-0-jellypro.img"]TWRPrecovery.img[/URL]
    10. After it flashes, hold Volume Up and Power, and type:

      Code:
      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!
      DO NOT MODIFY SYSTEM PARTITION or YOU WILL BOOTLOOP
    12. Flash Magisk ZIP to acquire root
    13. Back to TWRP main menu
      <<<ABOUT TO WIPE ALL USER DATA>>>
    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***
