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.

 

[AndreaKPiermarteri]

YYeeeeeeaaah!! More software for this little miracle!!

 

[Gyre8]

My Jelly Pro was delivered today. Looking good so far - just getting to grips with it.

 

[tomogo]

I'got my Jelly Pro today and need root. Any idea how to root my Jelly?

 

[pdue]

Custom roms for jelly ?

 

[Cralex]

It's a cool little device, and Unihertz seems to be making things easy for the users. Hoping to get TWRP on mine at some point.

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....

I successfully flashed twrp and supersu, but when I reboot, it just goes right back to twrp, and asks for a pattern to decrypt data... Not sure what I might have done wrong. I was able to reset things by flashing stock boot and recovery via fastboot. (as described at http://www.unihertz.com/bbs/forum.php?mod=viewthread&tid=67&extra=page=1&page=3).

I tried again (fastboot flash twrp, sideload supersu) and this time it worked! Just wanted to leave all this here in case anyone else runs into similar problems. Lovely having root again. Can't wait for Lineage to make its appearance!

 

[javadahut]

I ran into the same issue. When phone was delivered, /data was already encrypted.....with what key I don't know.

 

[tumbleweed1234]

User "vineethrp" helped me with a similar issue. He is the one that came up with the TWRP recovery and dumped the boot and recovery images. Here are the instructions on post 22:
http://www.unihertz.com/bbs/forum.php?mod=viewthread&tid=67&extra=page=1&page=2

The issue, he suspects, is dm-verity. DO NOT modify system when you boot into TWRP and click on "Keep Read Only". I was able to root and it is booting again.

 

[rich333]

can we use magisk su?

 

[Cralex]

I was having trouble booting up to Android with TWRP installed, even with the directions in the original thread, so I reflashed stock boot/recovery and installed Magisk Manager. (I was going to use Magisk anyway.) I used it to patch the stock bootloader from the original thread, then flashed the patched bootloader. Magisk works fine now on my Jelly Pro with stock recovery.

If you use an SD card, Magisk and Xposed won’t work unless they are on internal storage.

 

[invertedskull]

Wow, I'm surprised root was gained by someone on this thing, but that is awesome! I reckon I'll haveta do it to mine too!

Reckon this thread will get it's own "Unihertz Jelly" section? Moderators?

 

[ultramag69]

Yeah, would be good to have a forum to go to...
Will have to root mine now too

Bad customer service!!!!

Placed order through Unihertz website on 9/26/17. I have not even received a confirmation email regarding the order. I even posted to their customer "service" forum hoping to get some reply. It has been three weeks! Now I find out Amazon is selling the JellyPhone with Prime, while the Unihertz site is listing "21 days to 30" days for shipment. As a company that is trying to break into the consumer market(rather than OEM) they should attempt to take better care of customers.

I bought one on amazon and emailed service@unihertz.com to cancel my orders. They were still in 'processing' status and hadnt shipped.

I was having trouble booting up to Android with TWRP installed, even with the directions in the original thread

I've managed to install TWRP using that instructions. After that I installed SuperSU, then deinstalled SuperSU and installed Magisk. But one app didn't work well, so I decided to reinstall Magisk. And I've made one big mistake: haven't made backup, and got a softbrick. I've managed to unbrick it, but some things goes wrong.
So now I'm looking for stock firmware to flash. If someone can get TWRP backup of all folders except userdata and cache, please upload somewhere and post here the link.

I got along!

I entered into the stock recovery (long press on power button + volume up from power off state, and after the recovery loaded, simultaneously pressing on the 3 physical buttons and the "Home" soft button)
I chose wipe data, and then I chose booting to bootloader.
I re-flashed the TWRP recovery, entered it, and using ADB sideload to re-installed SuperSu, and I rebooted to System mode.

The system has been re-uploaded, and without encryption!

I think the problem was that I made a change to the NVRAM, and as soon as I re-flashed the stock boot and recovery, it checks the integrity of the partitions, and does not agree to boot if they are not original. As soon as I returned the SuperSu from the TWRP it canceled the test and allowed to boot as usual. Just a hypothesis, the main thing is that it works ...

 

[sd_shadow]

I would watch the Unihertz forum they may post firmware there sometime.

So can you please backup system and vendor folders using TWRP and upload? I need them Did you do the backup?

Btw you don't need to "simultaneously pressing on the 3 physical buttons" it works with short press power button + volume up. Sometimes it works at first time, but usually you need to press them several times.
