Zte nubia z9 mini (urgent help required) bootloop - ZTE Nubia Z9 Mini Questions & Answers

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?

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.

My first guess is a bad battery.
If that is not the problem, you could probably fix it by flashing a rom, either a stock one using odin(Not ICS), or a custom one from recovery(Aryamod maybe)
If its a bad battery then, performing the setup while charger is connected should keep the phone ON.
Before this problem battery back up was almost 1 day with moderate use
can i try factory reset with charger plug in as @nokiamodeln91 said
Tried setup with charger connected but this time also at at the end of the setup phone hang rebooted itself after reboot stuck at Samsung logo
kindly help

Also before flash using Odin, boot into recovery, fomat system, data, cache and preload.. then go to advanced... reboot download and flash the rom with odin .. or use recovery to flash a custom rom.

And yes, you just flash that rom from recovery, from your sd card.. After that you will want to do another factory reset, and clean cache.
Flashed with custom rom as you suggested @Azeazezar
but in this rom smoothness gone sluggish & poor touch sensitivity
what is the reason behind it
My stock JB was sooth enough
Use it for a day.

Need help - Stuck on static red logo

Hi all,
I was browsing the web on dolphin browser and my XT890 simply froze. After 5 minutes, I held the power button + volume down + volume up and the phone rebooted, but it got stuck on the red M static logo. Had to open the phone and disconnect the battery connector from the PCB so I could turn it off. Here are the facts:
1) Stock rom, 4.1.2 JB;
2) Can't get into fastboot menu;
3) With the phone turned off, after connecting the battery charger I can see the battery charging screen.
Because of 3) above, I don't think the phone is dead. Can any of you guys help me?
Thanks in advance.
Update:
Managed to get into fastboot. Did a wipe data / factory reset but after rebooting, it still got stuck on the static red logo.
Will flashing the stock rom again with RSD do the trick?
Thanks in advance
If u have access to the recovery, than a full flash with rsd lite will help (almost always) Do use the latest version of your firmware if JB has been installed on your phone. When JB hasn't been installed on your device, than any firmware can be flashed.

Thanks, mate. Flashing worked.
I just noticed that the SD card does not work anymore, probably that's what caused the crash in the first place. Replaced the SD card and it's working ok for now.
Cheers.
Hi,
I've exactly the same problem. Went to shut down the phone and it hung. Power and vol down to reset and the static red logo. I can get into fast boot and even android recovery but factory reset and full data wipe have no effect.
Could I flash a rom from android recovery? If so which one (phone was updated to JB a year or so ago). Otherwise do I need to use RSD lite when I get to a PC?
Is the internal sd card a standard micro SD card?
Many thanks,
Nick

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)

need help, regarding xperia T lt30p cant turn on

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

HELP!! Le2 x526 Not booting Up, nor Charging

Hello Friends,
Yesterday I was chatting on whatsapp and suddenly my le2 restarts, and then a blue splash screen appears and device keeps on booting,
hence I went to recovery and clear the data, but that also didnt help me,
Then i flash the 13s rom via Flashone 1.9 then also same problem happens, sometimes it went to optimizing apps 3 of 4 and again restarts with blue LED, i were unable to switch it off,
after draining the whole battery I keep mobile to charge but now it is not charging, it only showing Red Solid LED Continuously.
Now I am also Unable to boot into recovery or fastboot mode.
I again flash the stock 13s rom via flashone 1.9 , i got success msg but then also mobile is not booting nor it is charging.
Note: I am on complete stock rom on locked bootloader, never unlocked or rooted, used as come in box.
Please give me a solution on this, I have searched everywhere but not getting any solutions.

Cable is ok. I have another Le2 and it is charging with that cable very well
I am facing same problem. How you solve this issue? Blue led blinks after flashing any rom and bootloop.

Hello Friends,
Yesterday I was chatting on whatsapp and suddenly my le2 restarts, and then a blue splash screen appears and device keeps on booting,
hence I went to recovery and clear the data, but that also didnt help me,
Then i flash the 13s rom via Flashone 1.9 then also same problem happens, sometimes it went to optimizing apps 3 of 4 and again restarts with blue LED, i were unable to switch it off,
after draining the whole battery I keep mobile to charge but now it is not charging, it only showing Red Solid LED Continuously.
Now I am also Unable to boot into recovery or fastboot mode.
I again flash the stock 13s rom via flashone 1.9 , i got success msg but then also mobile is not booting nor it is charging.
Note: I am on complete stock rom on locked bootloader, never unlocked or rooted, used as come in box.
Please give me a solution on this, I have searched everywhere but not getting any solutions.
Thanks in advance

I also have the exact same problem. Phone started rebooting as soon as it booted up. Somehow i managed to unlock the bootloader, but to no avail. Can't seems to find any rom which can boot up. So practically i have a bricked device with trwp. Formatted the system and other partitions with twrp, flashed many roms. Still the result is same. Bootloops.
Hi,
try to to reimage your phone with QFIL from this site:
https://www.techpoison.in/2017/12/how-to-flash-letv-le-2-x526-stock.html
I downloaded everything from there, QFIL, Sparse image and drivers. My phone was bricked, but its working normally now. After you flash the image your phone should charge normally, just try to boot it up. In my case i had issues with baseband, not detected, no sim function and no wifi and phone was restarting each 3-4 minutes, but it was operable. Basedband issues can be solved by hard reseting the phone and updating it to 21s using the local update, just put the 21s stock renamed to update.zip to internal storage and run system update. When you get the error - APK missing, just boot it up again and retry the local update, should work fine the second time, i just deleted the update.zip and put back again and ran the update.

Flash the 21s bootloader + modem, one ZIP file, should work fine. Not sure what ROM did you install last time. You can give it a shot with with MIUI 10 - its nougat.
I had similar issues, see my topic, maybe it helps a bit.

Brother same thing happened to me, a week ago. I cant say about your problem but my problem was due to faulty power button. Actually due to that reason my phone actually kept restarting itself. It showed red light blinking while charging and wasn't able to bypass the optimizing app screen. I also thought it was a software issue but actually it wasn't. I spent about 2 hours figuring out what the actual problem was. The problem was: As we know when power button is hard pressed for about 10-15 seconds it reboots itself.
Although the repair shop guy didn't put new power button but he added a tiny piece of paper in between the power button and body housing to prevent the issue and voila the problem was solved.

Hi, Thanks. I actually did that first, flashing through qfil the same rom. it helped me to go to settings after umpteen attempts to go past language selection screen, and i was just able to oem unlock and enable usb debugging (actually after a 2nd partial failed flashing). the phone kept freezing within seconds of booting up. Now After i unlocked the bootloader and installing twrp and flashing many roms thru twrp, i am still having the same problem of booting up and freezing at start-up. cant flash again through qfil, as i will again loose the unlocked bootloader and twrp.
At least , now i can try different roms to see which can unbrick it. last one used was the twrp flashable rom based on eui (small eui by aurel) but it also freezes on language selection screen or beyond.
I am running out of ideas, lets see.
2nd partial failed flashing? any issues during the flash process? i had some issues when i used usb 3.0, 2.0 worked fine for me. If you have also charging issues stay in twrp and let the phone charge properly, its slower but should work fine. You can try to flash the 21s bootloader with modem, maybe it will boot properly. But try it only when you are able to enter the fastboot mode, longpress volume down and power for 10-15 seconds, if that is working you should be able to flash twrp via fastboot and you can experiment a bit. Try to find the chinesse twrp 3.0.2.0 and try to flash the stock 21s version. Should be also an image file, in standard twrp go to install - image, after selecting the image file click on recovery and install, after installation go back, reboot, recovery. Copy 21s to storage, wipe data, cache, dalvik and flash it, chinesse twrp will skip version check and will let you install the stock image, after install reboot but click on do not replace recovery button - this will keep the chinesse twrp installed.
If nothing helps it can be only a HW failure, maybe the power button, try usb 2.0 port during the flash process, i had issues with 3.0 on my pc, if that doesnt help.try a different cable, no more suggestions, sorry.

My phone has been flashed multiple times by qfil method. And always it hangs at initial setup (so it boots up, but hangs at language selection or further up screens, before setup can complete and launcher could be loaded).
While trying to flash again with qfil once it stopped at 25 percent (because the battery went dead). Charged the battery and booted up the phone, and i was surprised it booted up. After 2-3 attempts i was able to reach the launcher screen and immediately enabled developer options and oem unlock / usb debugging. Only had few split seconds to do this and the phone froze again. After that i installed twrp and hence treying different roms. Most fail at setup.
Just tried MIUI 9PRO ROM. It also froze at setup multiple times, but once i was able to complete the setup and miui launcher is up , but it reboots or turn off the phone just after that. So cant do anything with the phone. Unsure of whether a newer bootloader will help in these freezing issues as i have been able to boot up at least in some roms only if for few seconds. Will try to tinker the settings of miui rom (if the phone let me do it before freezing/hanging). Lets see. Thanks for suggestions. More suggestions welcome, because i am still unsure weather this is a software or hardware related problem. I am guessing that it may have something to do with Google security as earlier i was getting msg that phone has been wrongly resetted and needs to verify with Google (but i couldn't get a chance to use the same account, as phone kept freezing at setup).
Did you fully charge the battery, if not let it fully charge in twrp. Flashing the roms in twrp works everytime or do you see any errors? Before you flash anything disconnect the usb cable.

Try to flash the 21s bootloarder with modem, one zip using twrp. Go to fastboot mode and wipe modems. fastboot erase modem1st fastboot erase modem2st. Put the phone to flash mode and reimage with qfil. Before you do it write down both imeis, you can find them also on the original package on the backside. Also try to remove all sim cards from the phone and try a different cable. If nothing helps, hw issue, maybe the power button mention earlier in this thread.
After reflash skip everything at setup and reset phone to factory defaults. OEM is already unlocked, you dont have to do it again.
I have charged the phone fully before any flashing after that error. I can flash the phone through twrp without any error msg. The phone boots up most of times in various roms but hangs at or after the initial setup screens show (like language selection etc). Flashed the modem+bootloader, success, but it showed bootloader version as 20s (not 21s). Tried the commands u mentioned to erase modems, it say error failed, no such partition found. I had checked the partitions with parted and 56 partitions are there including the modemst1 & 2.
Now re flashed via qfil , did as advised but again the same problem of hanging / freezing at or after initialization screens of various roms.

Yeah sorry i screwed the command its fastboot erase modest1 modemst2, my bad.
Just now i was able to complete the initialization (setup screen) of sparse image india rom. I can reach the launcher and settings for few seconds before the device freezes or reboots.
So the same problem , with which i started, the only good thing is that i have been able to set oem unlock to on, so that i can flash trwp and various roms (but all fail with the same freezing issues)

So you erased modems and reflashed with qfil right? If so i assume its a HW problem. Try the fix with the power button, i ran out of ideas
Last thing which can help maybe: https://www.youtube.com/watch?v=LH3VOIlLfvo&t=135s
Download 21s stock image + the chinesse twrp, links should be under the video, i think so, or look somewhere in the forum for new links. Try to reflash the 21s, some people reported that freezing issues were gone after installing the latest EUI. Basically you can do the same after QFIL reflash but you need enough time to copy the ZIP file as UPDATE.ZIP to the internal storage and run the local update via setting, system update and local update, i hope that TWRP will work for you, just follow the video tutorial.

Did that also, the same problem. The phone freezes after the os is booted. I was wondering what is that isnt touched by flashing ( in download mode or fastboot mode or through twrp). I may need to tinker that. The roms are all fine in the sense they all stop at the same points. Something in the phones partition, which isnt touched by flashing? (There must be, as i flashed with qfil, the oem unlock remains, the bootloader didn't lock, and it remains unaffected by re-imaging)
Try this, maybe it helps:
