Hi ,
I am new on this forum so sorry moderators if i have posted this where i shouldn't have . I recently got a ZTE NUBIA Z9 Mini and i wanted to root it so tried different methords and somehow i managed to soft brick it or as they say its in a bootloop. Whenever i try to boot the phone with volume up button + power button just the home screen nubia logo appears and it stays there. I am absolutely clueless what to do ... followed some youtube videos to flash new rom using fastboot but apparently it needs back up files which i don't have .
Someone please help me
Thanks !
Possible Fix?
Hey have you tried to boot to recovery? it can depend where you brought it from. I got mine directly from the nubia store on thier website and it came rooted with a recovery system already in place, i had the same issue as you I booted into recovery power+vol down downloaded the rom again or most up to date rom from the website or in my case needroms website . Then i just installed the rom from update on the sd card View attachment 3357925 then it took about 3-5 mins to install and i rebooted it. View attachment 3357928 After this it should be as normal like flashing any rom onto any android device then wolla done even all my apps and data remained safe because it was only a software update flashed over.

I have the same problem.
If I press volume - and power device doesnt go to recovery, it just show Nubia logo on the screen for a while, then screen is black, That is all. If I plugg it into PC, computer can see one part of partiition with -Image- directory and a few unreadable partitions..
Do you know what to do, please????

Don't do nothing I had the same bug here with the logo Nubia again and again.
Just let the phone discharging itself (as you can't remove the battery).It will take around 24 hours.
Put an official rom on your sd card.
When the battery is out (try to power and if nothing happens it's good) just plug your phone to charge (not on pc) and try to go to the recovery.It should works.
Then load the official rom and after you will restore your backup (if you have one).

I tried this already, just without sd card. Problem is, that I cannot go to recovery. If I press volume - and power I'll get just on logo screen, nothing else...
If I plug completely discharged phone on charger and press nothing, then just charging procentage appear for a while and then is dead again.
you can use one-click-tool.
first you switch off your.....try two or three times....or try again and again ....if you switch off your fone....then try to switch on in to fastboot....i have downloaded a fast boot rom..........1.16 version........extract the downloaded folder then first you click on ....z9 mini app in this folder.....and connect your mobile to pc......its start in automaticly.......wait for restart.......ohla....your mobile runs....https://drive.google.com/file/d/0B14zmeE7OLybaW5KWS1rME1Fd0U/view?usp=sharing
Problem solved!!!
This helped:
- Use a fast microSD card and copy on the root folder the original Nubia ROM (you can download it on the first page of this thread)
- Insert this microSD card into the phone
- Turn on your phone and let the battery completely discharge
- When the phone is turned off, press and hold Volume - than connect your AC adapter (USB cable connected to PC does not work), en Should start in bootloader menu
- If you can successfully start the bootloader menu, run the phone into recovery mode and than install the rom from external sd card
At the moment there is not any tool or bin format image for this phone

where is the rom?
Hi @ all.
I have managed this problem using volume up and power button. After first bootscreen hold the on button and wait until the second boot screen turn of. Release all keys!
Thats all.
The smartphone is off and you can return to recovery.

Thanks a million, it saved my phone
Hello everyone!
I had the bootloop problem and I could solve it following your recommendations. My problem is that the original ROM installation process was suddenly stopped (I don't know exactly why) and now I have no access to the OS. Everytime I reboot it, the system goes to the bootloader showing this message:
Bootloader Menu
You entered this screen because:
No kernel (boot partition is bad)
Now you are in fastboot mode
The phone is fused
Then I have access to TWRP or to the original Nubia recovery, but I can't install a new ROM. I can restore backups but when I restart the system it goes to the bootloader menu again. Any solution for this issue?
Thank you in advance!

Hi again!
I finally could flash the official ROM via TWRP. Initially I was trying to flash this ROM from the SD card, but the installation didn't work neither with TWRP nor with Nubia recovery. Then I copied the ROM to the internal storage and flashed it with TWRP with no more issues. Hope this information is useful for other members.
Thank you!

Hi once again, dudes!
As I told you this morning, I finally managed to fix my problem with the no-kernel message. However, after the reboot, I have lost wifi and bluetooth connections. When I turn on the wifi it doesn't even search for available networks. I have tried with official ROMs 1.16 and 1.19 and with a custom multilanguage ROM, doing factory reset (sometimes even system formats) before each ROM installation. Everything is working properly but I can't turn on the wifi and bluetooth.
Any idea or solution? Thank you very much!
Solution to WiFi and Bluetooth problems
Just to let you know that I finally managed to solve my problem with WiFi and Bluetooth. I got a backup of the 'persist' partition from a colleague's Z9 mini that worked perfectly and restored it in my device via TWRP.
RAW format image caputure
hi guys,
Since Nubia Z9 Mini runs on Android 5.0 (Lollipop version) with latest Camera 2 APIs with Manual control over camera, would like to know if the default Camera App supports Image capturing in RAW format.
Also can we use third party application like Camera FV-5 which supports RAW format image capturing feature in Nubia Z9 Mini,
Since you guys are users of Nubia Z9 Mini, pls. confirm this for me..
Thanks in advance..

And how do you let the phone discharging itsel if the initial screen with nubia logo dissappears after a few seconds???
It won't discharge itself because it switchs off every time.
Anyone can tell me what to do?
Thank you.
Problem with Nubia Z9 mini
I've had this phone for 1 month and installed this ROM - http://forum.xda-developers.com/general/rooting-roms/rom-nubia-z9-mini-nx511j-rom-twrp-t3142204
Phone was working perfectly fine this morning but I noticed it had only about 30% battery left so I tried to charge it and it wouldn't charge? Tried computer cable, original Nubia cable and even others and nothing charged the phone. So decided to restart the phone to see if this fixed it and now the phone is just stuck on Nubia home screen . Can't restart or turn off or anything.... If i press volume down and power button it makes the screen print/camera sound and that's all i can do.
I'm not the most technical with all the mobile software stuff ect but can manage if guided
Also the phone is becoming really hot
Would greatly appreciate some help with this
thanks
I have a different problem here . I had stock ROM (India) when I purchased. Very laggy. I rooted, loaded TWRP, put MIUI-6, it was better, all working, but a little laggy too. Later put [email protected] The ROM is good (faster, very clean and clear voice, faster wifi etc...) but later found data not working. I read somewhere that the ROM may not be suitable for Indian version. When I want to load back the backup of MIUI-6, I am unable to boot in recovery mode. Only Nubia logo appears with all combination of switches. I am able to enter into recovery menu (Vol- and power). When I select "boot into recovery mode", only Nubia logo appears. I saw the directories in the PC, there is no TWRP directory in the internal storage. I tried to once again load TWRP, in the PC I get everything o.k, but in the phone, it strucks at recovery screen, and hangs. I have to press vol- and power to reboot again. It reboots o.k. Now, how do I get into TWRP recovery? Is there anyway to make data working with the present ROM? I tried all, like, draining the battery ...... etc.... not helping. Some information in this regard will be of great help.
I have tried everything possible as below.
As the above case, I am also using Indian version of Z9 Mini. I have flashed TWRP and then flashed MIUI6 & 7 and after that I came back to original rom through backup. Then after that, once again I came to MIUI7, after that when I tried to came to original rom, I can't. So I have downloaded last ROM from [email protected] , that is 3.61 . I that, my sim cards were not detecting. After that, when I tried to open TWRP , I can't. Just Nubia logo screen. After that I tried One Click Root Tool to flash TWRP. At that time , when my phone gone for rebooting , it's gone. Now whenever I tried to boot the phone or boot into bootloader , only that nubia logo screen appears. When I tried to flash through fastboot , device is not detecting. Why so ? . No partitions are seen on computer . I have tried all above steps , but no help . When I tried that fastboot flashable ROM by vijay2 , phone reboots to bootloader and in computer, it flashes everything. But after reboot , it is as same as before . What to do ? . If it is the case of missing driver , then please give me a link for it.
If you get stuck in charge only mode, while running the latest cm12, and the usb menu won't show up in the settings tab (under storage -> more) just delete the file /data/properties/persist.sys.usb.config and reboot. It should restore it back to normal connectivity over usb.
Hi!
After i choosed charge only in my blisspop, my pc or my laptop doesnt recognize my zenfone even in bootloader. Tryied to factory reset, flash another rom but, tried your method but no success. I can only use adb over wifi becouse of this.
Worked splendidly...thanks!!!
wish i would have seen this before as i formated my fire to get rid of this.
Hi,
I have to pick up this old thread, because I have the same Problem with my Lenovo K3 Note on CM12.1. Deleting the suggested file and rebooting did not solved the problem. The file persist.sys.usb.config was not restored after reboot. Any other suggestions for me?

Many, many thanks. Every time I choose "charge only" my Fire 7th (KFAUWI) with Lineage 12 (austin) installed get stuck and I can't conect it to PC. The only solution was a factory reset to get it to normal (mtp/ptp conection).
Sorry to revive an old thread but I need to thank you. You saved me one month of searching for a solution. Worked like a charm.
Can I disable this "charge only" option? In case I choose it by mistake.

When I try to do into ...data... It says I need to turn on root access. How do I go about this?
Greetings XDA community, recently I've been facing a problem regarding my wifi which is stuck on "turning on" hence, it cannot be turned on from the toggle and the settings. This problem first appeared while I was in a custom rom. So I decided to revert back to stock firmware which temporarily solved the problem. After a while, the problem returned and doing some factory resets and clearing of cache didn't help. Other troubleshooting steps I've done so far :
a) Toggle airplane mode
b) Delete a wifi config file(I can't remember the name) using root explorer.
c) Turn on mobile data tethering
d) Flash a different Kernel
e) Downgrade from Nougat to MM
f) Reset network settings
g) Reboot/Poweroff for 5 minutes
Has anyone encountered this problem? If so, how were you able to get the wifi to work? Thanks in advance.

Go back to your stock rom and root it. Then get a root file explorer and go into System then into etc and copy the "Wi-Fi" folder and place it somewhere safe. Then go back to whatever rom your on now and put that Wi-Fi folder in the same spot. Delete the folder before you place the one from stock and give it 0755 permissions. Reboot and you're good.
Good morning!
I have Xiaomi Mi9 6/64 with OS Xiaomi.eu 11.0.5
I install magisk to root my device.
Yesterday, I tried to install an audio module on my xiaomi, using Magisk, but after restarting I have bluetooth with error. It turns on, tries to connect to any device and disconnects again, Bluetooth turn off. stays in a loop. The only thing that Bluetooth can do is to reinstall the entire system.
I've tried everything, but to no avail.
Would anyone have a tip?
I need a Help.
Sorry for my bad english!
Update:
I did a nandroid backup when everything was working, including the audio patches, however, when I had a problem, I formatted the entire device and recovered the backup. The bluetooth error continues.
