Jelly by Unihertz - the smallest 4g Phone Ever

[johnnynmonic]

Is there a sub forum for the Jelly yet? Want to see the ROMs that come out.

 

[Mr. Death]

You can download whole rom from my link and extract stock boot from it.

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).

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!?

 

[Mr. Death]

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.

Ok man i love you!!! I used your version of the flashing tool. It's just a bit different then my two i already used. Port scan worked immediatly!? I did the thing whith the setting, when device not recognized even if it was recognized and flashed the rom from 20171103. Now its booting up!!! :victory::victory::victory::victory:

Thank you again!! So never give up

hi, yes i used supersu v2.82 even on the the 20180926 rom with no problems. I'm on a Jelly Pro M version and for the official TWRP never worked. I use a old twrp image from old unihertz forum

 

[Mr. Death]

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!

I've tried it now and I can't turn it on without battery.

Thanks for trying, this is unfortunate for my project

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"

Bootloader

Does anybody know how to unlock the bootloader? I have contacted Unihertz but they do not allow bootloader unlock, very disappointing. Does anybody know a work around? >-<

adb reboot bootloader
fastboot oem unlock

after that you can flash TWRP, but it won't be able to mount encrypted data partition.

 

[marnold425]

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.

Hi,
can anyone post a screenshot of the battery consumption? I'm comparing few to see which SW version may consume less.
Thanks
