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.
So i wanted a new rom for the awesome features so after i had rooted and installed twrp custom recovery i downloaded cm12 then created a nandroid. I put my phone into recovery wiped everything except internal storage and installed cm12 and gapps. This is where my problems started, as much as i liked the new rom it wasnt connecting to my cellular network so i thought ok ill just recover my nandroid so i wiped everything except the internal storage and then started the recovery when it finished i rebooted and it goes to the warning bootloader unlocked screen and sits for about 15 seconds the goes black and repeats. My phone is a motorola moto x 2014 victara, any help is much appreciated.
Please give us more details:
1) can you access recovery? Try holding the "power" button for like 20 seconds and trying to reboot into recovery when the phone boots.
2) can you access fastboot mode on the phone? maybe you lost your custom recovery but can access the bootloader and that makes things easier.
3) what is your device number? (xt1097, xt1095, xt1092, etc)
You are going to want to factory reset. Most times coming from a customer rom to another or even back to stock you will need to do a factory reset in order to wipe out anything that may have been left over that could cause issues.

Your custom recovery is messed up, you may try this at your own risk
Download any rom for you liking (Custom or stock)
move it to sd card from pc, use the andriod one all in one tool or fastboot and try to root your phone. (Before that you need to have proper drivers installed)
The custom recovery you try to flash will boot. Wipe (factory) + Dalvik and data and flash the rom you had moved to sd card. Now your phone will boot with the new rom,
If you have succeeded, come back here for further instructions ...

Yes, the usb debugging should be on to perform that.
Try what hp5942 suggested
'Use volume up + power when the android with exclamation mark occurs.' You just factory resetted your phone, so give the first boot atleast 30minutes
Yes he's right the first boot\ boot after factory reset will take little more time, so be patience.
If it doesn't work, search for thread for factory image for your phone and flash it with flash tool. It will bring back your phone to working from soft brick.

When i was stuck in that screen the only way i found to get out of it was to remove the back cover and disconnect the battery
I have the same problem
-I have rooted my htc mini2 and after a while decided to restore the original ROM but everytime i turn on the phone i have that red warning message.
One day i decided to delete de TWRP backup files bacause it takes a lot of space on my internal memory .
Yesterday my baterry died so when i was turning my phone it gets stuck on that message screen . So i can't get through because on my internal memory i don't have the TWRP files to backup or get into recovery mode.
Is there any solution? i was thinking about putting those files on my sd card and see if the phone will read them?

No, not possible from SDCard alone, you have to flash TWRP by placing TWRP in PC ADB folder (ADB must be installed in PC and device should be able to enter bootloader and fastboot) and entering bootloader>fastboot on device, then connect device to PC, this only works on unlocked devices.
Command is :
fastboot flash recovery twrp.img
fastboot erase cache

Hey, i had the same issue. After rooting my phone, when my phone died because of the low battery, the same thing happened to me.
The solution is pretty simple, actually - you have to restart the charging unit of your phone.
So what you gotta do is this:
leave it to charge a couple of minutes (so it will have enough power to boot again) and then just press all the buttons of your phone at the same time and hold it for up to 10 seconds, so power button + volume up + volume down.
This will restart your charging unit and it will get your phone to boot normally again. :fingers-crossed:
I don't know why this keeps happening, but I have to do it all the time, if my phone dies. So I try to make sure it has enough battary not to die, because it is just annoying.
i have the same problem. if you hold the power button + volume up you can reboot your phone if it is frozen.

the trick is to keep hold of power vol up & vol down for 2 mins,it will boot,reboot,boot,reboot loads of times,keep hold for at least 2 mins,once you let go it resets itself:good:
make sure you have a some means of installing Android back onto your phone placed on your SD card or internal storage
I recommend updating to the latest version of twrp before trying these (I used 3.0.2.0)
twrp>wipe>advanced wipe>select everything but: "/Micro SDCard" "/Internal Storage" "SD-EXT" and "USB-OTG
after that install Android by restoring from a recovery backup or instal a custom rom onto your device (whatever floats your boat)
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.
