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.
hello everyone!
i have a few questions. and i have done my research yet i still find no solutions so i will ask here
this is my story...
-root,unlock bootloader,flash cm12 android 5.0.1, ran cm recovery
-running fine for around 2 weeks.
-in those 2 weeks there has been times where phone drained to 0 its battery, then charged it then it was fine
-suddenly one day. charged it after it drained completely. then wont turn on.would boot up to 'sony' screen then repeatedly reboot and do the same thing again.
-could enter recovery, but when trying to reflash rom, phone would reenter boot loop
-have tried charging for days.
-have tried removing battery, same thing
-then used flashtool, relocked bootloader, reflashed stock firware, now cant get into recovery, flash successful, yet phone still cant turn on pass sony screen.
is it a battery problem?
just to add, ever since the first time it started having this problem, i could never get the phone to turn on at all without plugging it in .
Hi Jetdin
had the same problem with my XT a year ago, when a powerbank somehow "nuked" the battery-logic... After that, I had the pleasure to know what a deep-discharge feels like :-/
To revive my XT, I had to replace the Firmware... I did it this way, maybe you can try a "factory reset", maybe it already works out for you...
1. loading it (turned off) 24h with original recharger (don't try to turn it on)
(1a - if you can reboot it to save apps, data, files - do it)
2. reboot into TWRP - and do a factory reset
...and try your XT; with luck, this already solved your problem... if not:
3. get the new image of your choice - i downloaded whiteneos 12.1 - works like a charm... and copy it to an sd-card
4. after (re)loading the XT - boot into TWRP - and install the new image...
...reboot and hope this solved the problem...
Good luck!!
Edit:
that it only stops at the sony-logo sounds like "operating system not working" - maybe a "higher" OS-version will do the trick?
Thanks for the reply theunlucky.
I have tried most of those.
The cm12 was on Android 5.0.1
The stock firmware for the Xperia T only goes up to JB huhu

3. reboot
4. if you see a led hit vol + ( or vol - ) several times until the led color changes
5. now you should be in recovery... try to flash cm12.1 from whiteneo and reboot

I can't boot into recovery, i have wiped all data through TWRP, and my phone won't get past the lg logo.
What Happened:
I rooted my LG-G4 H811 and installed TWRP too, yesterday, and i thought of trying out a custom rom.
I chose the CM 13 Rom, i downloaded the files.
i put them in the internal memory of the device, (since my phone has an sd card problem, a hardware one) i could've done that using OTG too but i didn't think of it that time.
I go to TWRP using my pc using adb, Because there's no direct method of doing it, not even with the volume buttons. tried them all.
Here's when i messed up
i went to wipe the phone data instead of flashing the rom and gapps first. I ticked all the boxes, and it did clean everything. including the rom files i was about to flash ( genius)
I went back to the main screen and i rebooted my phone and now it's stuck on the LG logo.
I can get into download mode by pressing the volume up button while plugging in a cable
i CANNOT get to TWRP. idk why.
Please help me :crying:
download kdz file with the firmware that you were running before on your phone get yourself into upgrade firmware mode by pressing volume up and connecting USB cable when your phone is turned off and run lgup application to upgrade the firmware and you should be ok unless you experienced bootloop phenomena on you lg4.
my galaxy note 4 (sm-n910t) caught in bootloop . i dont know what caused it. the phone simply restarts upto first bootscreen, ie upto 'samsung galaxy note 4' and then vibrates and then restarts.this process continues upto battery is down or i pull out battery.the phone is not entering to recovery mode but enters to download mode.
i have tried installing stock rom from sammobiles but it won't help.i have also installed custom recovery twrp but that also won't help to enter to recovery mode,
i am trapped pls help..
You didn't mention how you tried to install the stock ROM . Did you use Odin?
I just fixed mine with the same issue. I was able to boot into recovery and download mode but mostly download mode without bootloop when I had the usb cable plugged in. I used ADB when I could to boot into download mode, but the buttons worked too. Trying to restart the phone only lopped after the Google screen.
I followed several guides here to flash stock with Odin and wipe cache etc but none solved my boot loop issue. almost gave up but there is a video on You Tube that said the battery warping in the cause of the boot loop. The battery, after/during quick charge, may heat up and change shape causing the issue. Today I installed my new battery purchased on amazon and no more issues.
Now I am on stock and have to find a good rom.
If you do decide to flash back to stock there are a lot of good guides. You may find yourself stuck on the T-mobile screen for 15 minutes when booting for the first time but that is ok. If you still boot loop after installing stock and wiping cache I would try the battery.

hi OP,
did you find any solution to your problem?
Hello all. I'm also pasting this in the T-mobile thread in case it can be of benefit to someone. This is advice to use as a very last resort if you are experiencing the recovery bootloop issue AND you don't have the emmc failure bug. I had the recovery reboot, sudden shutdown with no warning, etc. issue for the past two weeks. I tried everything on Google and Youtube to fix my problem with no success. I flashed multiple stock ROMS and recovery tars (stock and TWRP) via ODIN, but nothing worked. Oddly enough, I never received the emmc error that I have read about. Also, in the few times that my phone booted normally, I even loaded the Wakelock Power Manager app, set it to partial wakelock and my phone STILL continued to bootloop. As a last resort, I bought a new battery, but the reboot problems continued in Android 4.4.4 Kitkat, 6.0 Marshmallow, 7.1 Nougat and 8.1 Oreo ROMS. Well, here is what finally helped me to get my phone back operational. I had a backup ROM from a previous install and a TWRP flashable version of the same ROM on my SD card (in case the phone did not stay on for the full restore). I put the phone into a ziplock bag into a freezer for about 20 min. (thankfully this time TWRP stayed on long enough for me to do the following):
1) copy all the files I wanted to save from internal storage to a computer.
2) performed a full wipe (Dalvic, Cache, System, etc. Like when flashing a ROM, but this time also internal storage. Note: Please do not wipe both internal and SD card, as you may have a difficult time trying to load the ROM file back on the sd card (assuming you don't have a card reader).
3) After wiping, I was able to restore my stock ROM backup (or you can just flash the stock ROM).
I can't be 100% sure, but I think my wiping internal and then flashing the stock ROM finally did the trick. Since this morning, the phone has been pretty much back to as it was before. In either case, I'm sharing this with the hope that it helps someone else.

Hallo, yesterday my phone kinda got laggy so i thought to my self hmm why not flash a new firmware. Aftewards i said to my self, why not go even further and flash lingeageos 16 and thats when it starts going down. The phone would crash or black screen (volume and power key still work and show their UI on the screen) while the rest of the screen was black. I panicked and quickly wiped everything system,internal storage and all that via TWRP recovery. Now i face a even bigger problem. I cant flash anything onto my phone. The Flashtool requires some drives which i installed as the program instructed but with no great result. I put the device in flash mode by holding volume up key and putting the usb cable into the phone and still nothing i can do. I tried various tools to convert the FTF firmware into zip so i can flash it with TWRP that luckily still works. If i try to flash anything i get the error: 7 or bootloop/stock on loading screen. What should i do?
UPDATE: I flashed a stock rom via newflasher, so for anyone in situation like me, where they phone is a very essential part of they everyday life and everyday responsibilties. Then i recoomend this guid for you, it says everything you need to know when you are in a situation where nothing works: https://www.xperiablog.net/2018/01/...-firmware-for-xperia-xz-premium-xz1-and-more/
