Don't root unless there's a reason you need it

Don't root unless you are prepared to deal with potentially bricking your device!

Also, you need to be familiar with TWRP already because the text is very small on the device so you need to know what you are looking at.

Download the supersu zip from https://s3-us-west-2.amazonaws.com/supersu/download/zip/SuperSU-v2.82-201705271822.zip or http://www.supersu.com/download to your PC.

Also download the TWRP.img linked elsewhere.

Also you will need to install "Minimal ADB and Fastboot" to your PC. It's a very small program.

Put the phone in bootloader mode and connect to the PC.

Open Minimal ADB and Fastboot

Type "fastboot boot" and don't push enter yet

Drag with your mouse the TWRP.img file to the "Minimal ADB" window and it will fill in the path so it will look like "fastboot boot c://user/desktop/twrp-jellypro.img" or something similar.

Push enter, wait about 30 seconds. You will boot into TWRP.

Suggest you do a backup at this point!

Next, go to advanced and select ADB Sideload.

Type on your PC: adb sideload (and now drag the superuser.zip into the window) so it looks like "adb sideload c://user/desktop/supersu.zip" or whatever your path is. Hit enter. Wait a minute,

Wipe cache & dalvik. Select reboot. Wait patiently while it reboots.

You have root.

[General Questions and Answers] FanboyStudios:
I'm thinking of getting one of these phones (probably the pro model), how is the battery life and reliability? Can I use this on Verizon and AT&T? How is the ROM support? Is there an official section for this phone?
[General Questions and Answers] Cralex:
Battery life wasn’t that great, but it seems to be better with recent updates and taking steps to reduce power consumption. It’ll work with AT&T and T-Mobile in the USA (plus smaller carriers that use the AT&T and T-Mobile networks) but not Sprint and Verizon. (It’s a GSM phone, not CDMA. Sprint and Verizon are CDMA networks.) So far, no unofficial ROMs have been released for it. It can be rooted, but the system is hardened pretty well and rooting can be complicated. Don’t think there’s an official section yet.
[General Questions and Answers] FanboyStudios:
Ok thanks for the info! Can the phone last all day with maybe 2 hours moderate use? Is it easy to root? I've rooted Motorolas and some older Samsungs like the S5 Sport and Galaxy Note 10.1 2012 Edition.
[General Questions and Answers] Cralex:
I use mine as a backup phone most of the time, (FreedomPop LTE GSM,) so it’s typically on Airplane Mode. (It can last on standby over two days like this.) Maybe tomorrow I can turn on cellular data and/or Wi-Fi and let you know how it lasts if I use it a little.

You can read some people’s experience with rooting it in this thread and at sites linked in this thread. I don’t have much experience rooting phones, but at one point my Jelly Pro was rooted with Magisk. If you go this route, which involves unlocking the bootloader, it’ll display a message about the bootloader being unlocked each time before booting up. I eventually reflashed the stock ROM onto it when it became unstable (rebooting itself, getting very warm, zapping battery life, eventually not booting at all) for some reason. Never could figure out why. Haven’t tried rooting since and it’s been very stable while unrooted.

As for rooting with Super SU, that typically involves TWRP. When I tried installing TWRP, it failed to boot, claiming to need some password. It’s been done, you just need to look up how to do it.

My advice for rooting it is to not do anything important with it before you start trying to root it, in case you need to start over, and to keep a backup when you have it working the way you want.

Edit: Yeah, I think you can expect a full day with light to moderate use.

This phone makes me very frustrated.

My idea was to unlock install TWRP & root to be able to install pico gapps adblock etc to debloat all Chinese crap program.

I have only been able to unlock bootloader.

All the rest has failed. I had to reflash back to default when I bricked the phone.

Is there a updated instruction that works?

Unihertz hompage with support forum has much room for improvements...right now it is really useless support forum.

Call Sound Quality

Can anyone here chime in about the sound quality of their phone calls on the Jelly?

Some users are complaining that the other end has trouble understanding them.

I'm having this as well on phone calls and Hangouts calls, but WhatsApp and Facebook calls sound fine. (I would guess it is a problem with noise reduction or echo cancellation software.)

One user here reports getting the unit replaced. https://www.unihertz.com/bbs/forum.php?mod=redirect&goto=findpost&ptid=49346&pid=52106&fromuid=34598

Hi,

Yes, I did get a new one. I posted two Threads about that topic in the Unihertz Forum, but I can`t post the links here, because of the xda rules. sorry...
[General Questions and Answers] harryspar:
Jack, how did you get them to send a new one?
[General Questions and Answers] jack24M:
I tried to attach some Mails here, but no chance... sorry.

In the mails they accepted my issue, after they tested it on a Jelly Phone.

In the Mails, they said, that they tried my Samplefiles at a Computer. After those tests, they told me that the Carrier where the issue.

I complained, that I can't use the divece as a phone and I attached new Samplefiles from me with an external mic and a build-in mic test. After that they told me to send it to them, because they tested it on a Jelly from them.

At First I had conntact with the service Team and after a few mails they looped the technical support team in the mails.

I hope it will help you.

Download the fw update package on unihertz forum and flash back to stock with the attached flash program.

This I have done 3 times now because I fail to install TWRP and root. (I have the latest version n)

In my mind the phone is not useful with the original fw and its more like a toy for kids ,maybe someone develops a better rom in the future.
[General Questions and Answers] stratosmacker:
Has no one then been able to build a new ROM for this device? It's such a compelling piece of hardware, it's a shame the manufacturer isn't releasing any source to do so. I would use one in an instant, but I'm not going to run some strange firmware that I don't trust.

[General Questions and Answers] grundigboy:
I hope this does not mean the support for Jelly Pro is or will be abandoned soon. Unihertz has announced Oreo for Jelly back in March. The last Nougat update was released in March and it did not get more reliable with it even worse. The Atom looks impressive, but as long as Unihertz is showing such a short term and not satisfying firmware support, I will not buy any new "next great thing" from them. Usually I use my phones longer than two years, so I don't buy a phone every year.

Have a nice weekend

FYI: Custom Rom work for the Jelly

Some guy on Github works on an Custom-Rom for the Jelly pro: https://github.com/LineageOS-MediaTek/android_device_unihertz_jellypro

He even has an blog, where he released an build for Resurrection Remix: https://samarv-121.blogspot.com/2018/06/rom712unofficialbeta-resurrectionremix.html

He uses the prebuilt Kernel from the original rom.

I didn't tested these ROMs or worked on these sources. I just found the sources when I did a search for "github jelly" on Google....

It seems that he has an account on xda, but it is disabled :confused:

[General Questions and Answers] droidzer1:
Has anyone with a Jelly Pro and TWRP installed tried doing a RESTORE with TWRP? I found out the hard way it won't do a restore and won't even try due to some error about decryption. Error was in such tiny font I couldn't read it even with a magnifier. The version of TWRP made for this phone by user SamarV-121 on the Unihertz forum doesn't seem to have much support about issues with it. Even the method the developer lists to install it will fail on Nougat unless you modify the file recovery-from-boot.p in the system folder by renaming it to something else. Othewise your phone won't boot anything except TWRP.
[General Questions and Answers] droidzer1:
Found the problem above with TWRP was likely related to using too old of a version of TWRP on Nougat. Had to use SP Flash tool to start all over to fix things. Now TWRP mostly works with some minor errors regarding /data partition. Unfortunately use of the SP Flash tool will always cause both of your IMEI numbers to end up as all 11111111111111's or 22222222222's.

I found a fix for that after about nine hours of trying everything under the sun. While Xposed Framework has some modules that can fool the phone into seeing a good IMEI it is not really flashed into the phone and if you remove Xposed Framework it will go back to all one's and two's. I personally don't care for the overhead Xposed Framework has, the slowness I've seen on some phones when it's installed and some lockups and other issues. On the Jelly Pro it took some 10 minutes just to boot up on the first install. After uninstalling it I still found traces of Xposed Framework left behind. I know a lot of people like it but it's not my cup of tea.

So I found a little tool that permanently writes the IMEI and that tool can be removed after it fixes your IMEI and you will still have your correct IMEI. You can find it on various sites but even if it looks like the latest version you will probably need to allow it to download the latest version (it asks you to do this when it is first run) for it to work. I tried two previous versions which did not fix the IMEI but the latest did WORK! You also need to have Wifi working while you modify the IMEI. It asks you to 'share' the tool before writing the IMEI. I just shared it with Total Commander as a text file and that worked. The App is called Toolhero. After it writes the IMEI it asks you to reboot and upon reboot you'll find you have restored your correct IMEI numbers.

Hi everyone.

I managed to brick a jelly pro (already updated to android 8.1) during the rooting process.

I tested to flash TWRP using fastboot without problems. Problem was, I got errors trying to flash supersu from TWRP using sd card (couldnt reat, font is too tiny, but maybe logs are inside sd card, arent they?)

So I rebooted to system, in order to try to copy the zip file again to sd card.

I still got errors.

So I decided to test flashing TWRP using last version of sp flash tool instead of adb/fastboot tools, thinking that could make any difference.

I re-flashed TWRP, but I also flashed a pre-loader file that came with the pack.

Since I flashed the pre-loader, phone has never booted again. black screen. even charging, no battery animation is shown.

It responds to sp flash tool, so the preloader some how is working, but the phone never loads nor system nor recovery. It keeps in black screen. So you only can use sp flash tool with it.

I flashed the full strock rom with all parts of the scatter file (this includes a preloader, boot, system, etc). Using "dwnload only". No dice.

I tested again using "format all and download". No dice.

I tested again using "upgrade". No dice.

I usually got "error 4008" at some point flashing system, but repeating process seems to be effective and I reach 100%, but it suggests some kind of problem with the flash.

So, basically, after a full firmware upgrade with stock rom, still phone is almost dead. Only sp tool is able to comunicate with it.

Can someone help me to return the phone back to an operational state? Is there some more information that I could provide?
[General Questions and Answers] Olangu:
Ok, so after spending a day trying to get this to work on my Jelly Pro I realize that I have a Jelly Pro "M"-variant. What's the difference? Another processor? Is there any chance we'll get LineageOS and TWRP for this version? It's so annoying.

Appreciate if anyone could explain why there is two versions.

Thanks
[General Questions and Answers] Cralex:
I don’t know about LineageOS, but the developer of TWRP for Jelly Pro said he was working on a TWRP for the M variant. In the meantime, it’s possible to root with Magisk if you want. That’s what I did with my M variant. You just need to be careful that you don’t install addons that cause a boot loop or something.
[General Questions and Answers] droidzer1:
Most likely you have the wrong ROM - flashing the 6737M on the 6737T or vice versa will cause this black screen problem. Earlier Jelly Pro's had the 'M' version and later ones had the 'T' version.

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!?
[General Questions and Answers] 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.
