Hey friends,

As I already informed you in the "geekbuying firmware" thread, I have ordered a Nubia Z17S with "gobal rom". See here where I got it from: https://nl.aliexpress.com/store/pro...hone/708786_32837057331.html?isOrigTitle=true. I have 2 subjects to discuss with you. One is FOR you, one is where I need help :).

GLOBAL ROM UPLOAD:
I got the phone in, just a few days ago. But it appears it really HAS a stock global ROM with full Google Play support, everything works! It is the EN_COMMON v1.02 ROM.
If you like, I can make a backup from this ROM and upload it for you guys, in order to see if you can cook a compatible Z17 ROM from it?
The only question: How do I do this, WITHOUT rooting my phone, if you have a tutorial for me, I will try for you.

Mobile Iron not installing:
Why I ordered a Z17S with the global ROM, is that I am NOT allowed to root my phone. Why: I need to have Mobile Iron installed, a secure enterprise cloud service, used for my work email. See here: https://play.google.com/store/apps/details?id=com.mobileiron&hl=en. Normally on my other phones (for instance the Z9 mini) it was no problem to install this app, as long I had an official rom on it. It was always on a Android 5 ROM. However, now, the APP is not installing and gives me the following error: "Your work has set up a work profile. If you like to use [email protected], use the version with badge that has been installed on your device". The problem is however, that my company does NOT have installed ANYTHING yet on my phone. Searching around on the internet shows that also Samsung users with Android 7 have this issue, as there is a secure folder installed that is not allowed by Mobile Iron, see here: https://forums.androidcentral.com/a...galaxy-note-7-unable-install-mobile-work.html. So, my question here is the following: Does the official Nubia ROM have something like a "secure folder" option, or anything like that? And if so, how can I uninstall that? I tried to look around myself, but no luck.

In summary: if you could help me with the Mobile Iron installation, I will help you with the Z17S ROM (and even if you cannot help me with the Mobile Iron installation :)).

Sorry but for twrp I need to unlock the bootloader, which I can't do.
Finally I was managed to get it working. Now my phone is rooted with just two or three steps. Really easy to do :).
1. In your phone, Open settings, about phone, tap many times on a build number to access the developer mode and enable USB debugging, enable also OEM unlock!
2. Download this file: https://1drv.ms/u/s!Aibwba12yUANjd4Ss0xEQErPtMrfTw
2. Unzip the folder somewhere to your disk
3. Run recovery.bat
4. Close the opened website and in the opened command line, press 1 and enter to install drivers
5. Press 2 and enter to install TWRP, after the installation is finished, the phone remains in a fastboot mode but you will see press any key to continue in the command line (don't press anything on the computer!) you have to press volume down on your phone to choose reboot to recovery mode and confirm it by pressing the power button
6. Voila, you are in a TWRP. In TWRP first of all, if you have a set pattern or a code, type in the code or a pattern, select language and confirm by pressing the blue enter button. You can also choose your language (for me English). Swipe to allow modifications.
7. Navigate to advanced, tools and root device, swipe to confirm
8. Wipe cache/dalvik and reboot to system.
9. Download root checker and check if you are rooted.
10. If you want to boot to the recovery again, I think this is a temporary TWRP installation. If I tried to boot to TWRP again, I just got into the original recovery. BUT the root still remains! And if you want to unroot the device, you just tap to unroot device in TWRP.

11. If you want to get into TWRP, again repeat steps 3 and 5 - Just open the recovery.bat and hit 2 to install TWRP, then get into it and make a backup.

MOREOVER, I was able to make the backup! So if you could make the backup (I skipped the data part because I think it is not so important since there should be just some apps data and other things not the system files), but please make a backup of your rom and upload it somewhere. Please give it a try :)
Thanks in advance

unlock bootloader,
flash twrp,
make a backup
flash official recovery if you want
lock bootloader if you want.


you are still not rooted so your iron will go on working. any many no zero operation done to ROM - system so you are still unrooted.

Thanks, but as I mentioned, I cannot unlock, root or reflash the device, sorry!
Once again, did you try my method?

I also couldn't unlock, root or anything else. But with this manual, you can do that. And then you can unroot your device easily if needed.

BTW. Guys, is there anyone who could make his backup even with the Chinese rom in TWRP?

I accidentally formated data and now the phone cannot boot again, the only thing I can do is get to the TWRP but I cannot do anything else. Please someone, make your backup and post it somewhere to download.

Thank you very much.

Sorry but you don't get me I am afraid ... I mean I am not going to risk my 600 euro phone to root unlock and reset, as the Z17s has no solid twrp and I do not have a international ROM to fall back at the moment. If something goes wrong, which is very likely (see your own situation at the moment), I will be stuck for weeks or longer, and having the risk to never be able to install Mobile Iron anymore.

So to be clear, I will be more than happy to make a backup of my system, but if this involves rooting, unlocking or reset, I cannot help you. Sorry!

My situation was totally different. It was just my fault that I did a full reset with all the data erased:) but I am back alive. Just flashed the old recovery and stock rom. So a quick and simple solution. Hopefully there will be someone who is not so afraid.

The method I posted is 100% safe. I have tested it and worked like a charm. I was managed to install Google Play and other services so I am happy now. Do not need the geekbuying rom. Because there are no updates which I would miss.

Anyway, thanks.

Rome
Please allow a couple of stupid questions:
-Is this ROM you linked ( NX595J_Z69_EN_VNG0N_V105.zip ) compatible with both the models? (6/64 GB and 8/128 GB?)
-Is OTA update possible once they're installed?
-Are they already equipped with google services and stuff?

Thanks to whom might answer
