Unhappy IMEI Invalid, totally stuck! :(
Hi all,

I'm new to smartphones and all this tech in general. I recently purchased a Ulefone U7 smartphone and stupidly flashed the latest Android v4.4.2 KitKat ROM via the Ulefone site using SP Flash Tools. Now the phone says my IMEIs are invalid for both SIM slots and I'm unable to change them.

I've tried changing them via the Engineer Mode AT+ commands but get the message "This command is not allowed in UserBuild" or something similar.

I've also tried changing them with Droid Tools v2.5.3, but nothing sticks.

I'm unclear as to whether root is required or not. In any case, I can't root with SuperSU.

I've tried most things to root, but the only thing that seemed to work was VRoot. I then tried replacing VRoot with SuperSU via both methods listed by gammelobst in a previous post, but seem to be missing something.

Trying these methods, I run the .BAT file and get the message "/system/bin/sh: su: not found" and am not prompted to grant root to ADB.

Can someone please help me rescue this phone from being a paperweight? I'm all out of ideas and all the lingo phones use is new to me.

Thank you from the bottom of my utterly exhausted heart...

Hi

Do you have a backup? Guess not
Have you tried to flash the origional 4.2.2 rom from the ulefone website? Mostly this would solve it

Just tried this, and although the IMEIs weren't restored, I /was/ able to successfully send the Engineer Mode commands, reboot the phone, and keep the proper IMEIs intact. THANK YOU!!! My only question now is: can I keep the IMEIs intact /and/ upgrade to 4.4.2? I've read that 4.4.2 doesn't tolerate those Engineer Mode commands, and that a factory reset will reset the IMEIs...

I also notice that on the Ulefone site [link deleted 'cause I'm new] there are two Kitkats, one explicitly labelled as such and a later-dated one with a gibberish description. I've only tried the latter. Would that make a difference?

Again, thanks for your help!

Hi,, just out of curiousity
Why still want 4.4.2 and have the volume, camera and storage bug, when 4.2.2 works out of the box

Just settle down, root your phone and get the proper recovery
Install exposed framework and the desired modules and make this device your own. You dont need 4.4.2 really. Better yet, wait for the 4.4.3 version

Just my thought dude

The engineering mode works, but on my u7 you have to insert a space either before or after the plus, I can not recall to make the command take.

Unfortunately there is no Kit Kat update for Tronsmart P7. Has anyone put Ulefone Kit Kat ROM on Tronsmart P7? I am wondering if the ROM is compatible given that those phones are almost identical.

Would appreciate some feedbacks. Thank you.

As the specs seem to be identical, I guess now it comes to which brand is better known for good built quality. I know Ainol mostly for their tablets and Tronsmart for TV box. I haven't heard Ulefone before.

Also to be considered the chance of manufacturer to release ROM update. And of course, the chance there will be custom ROM contributed by developers.

Anyone can share any feedback on any of them? Thank you.

Chinese manufacturers unregularly update the firmware. Ainol may be more famous and have english site ainovo . com

Im also looking into one of those 7" bad boys.

But i also need my next device to have BLE (Bluetooth low energy) for fitness tracking. Do you guys know if any of those devices do have BLE capabilities? Is a 7" phone with BLE out there generally ?

thanx so much. the internet is very quiet about BLE so it would be much appreciated if a happy owner could check (pretty please )
