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 All
Sorry to bother you again with my troubles.
My xz1 compact (with LOS 17.1.5 last version of OS , Sony Firmware .228) wasn't charging battery anymore last night (no way to make it charge) , and went off out of battery. I dissasemblied it to check and clean the charging port, and the current came back and charged the battery full. But after reassembly the phone booted and stay stucked on start screen with unresponsive screen.
No way to unlock, no response of the touch screen, no ADB operation possible as the phone was "unauthorized" in the terminal window. .
I went rebooting on TWRP recovery to back up my files, and there the screen worked perfectly ! i could do my backups, wipe everything and reinstall LOS 17.1.5, but again on startup the touchscreen is away !! ... the touch screen looks fully functional when on TWRP, could it come from a software or hardware issue on my phone ? .
Someone in my city told me that I've could have boken one small resistors near to the screen connector on motherboard, but I can't see anything when comparing to the motherboards images
Bye and thanks for your help.
It's incredible, as I can perfectly manage the phone on TWRP recovery app, but no way to do anything on screen when a system is booted
Hello all, still trying to fix that problem... After full wipe and formatting (via TWRP, screen is working on it), and reinstall of LOS I get system to boot, but with black screen, the phone react to button press (power and volume), but no to any screen command . Is there a way to test services and perpiherals with TWRP ? Tryed to move back to sony stock firmware .228, but with bootloader unlocked it's not possible. Thank for any hint or suggestion, bye.

I'm running .228 with an unlocked bootloader. If the flashtool or Newflasher isn't working then you need to use Sonys TOOL. As for your main issue, I have no idea, it is strange though.

Thank you @SXUsr yes it is a strange issue, as the screen works with TWRP, and the hardware looks no faulty .. my only clue is that I've touched and clean the Charging port to cure a bad connection ( and it's charging directly now )
I will try to reinstall Sony .228 from newsflasher or Sony "Emma" tool (thanks a lot for the link I couldn' find it by research) and I will maybe know if it's a soft or hardware issue !
Firmware .228 reinstalled from newsflasher . the screen seems to work .. the telephone is still with bootloader unlocked ... Now I'm back on ungoogling it . Thanks
I just wanna ask after the oct update i got bootloop now when i try to go to service center they told me that the problem is the motherboard. When i explain to them the reason i just update it then bootloop they always tell me the problem is motherboard. And i need to fix it and the cost is half the price of the phone. Now i need some help. When i try to turn on its stuck to androide one then off whne i try to go to fastboot its okay. When i charge it it turns on and off. I jus need some help.

is your bootloader unlocked?
If so, have you tried booting latest twrp image from fastboot?
Code:
fastboot boot twrp.img
Sounds like you may at least have to try to wipe and format your phone at the cost of all data.
But then you could use the situation to install a good custom ROM..
If you were doing a normal update, your phone should revert to the previous slot after a few attempted reboots.
Keep trying to reboot.
If nothing else works, try flashing september version from EDL (search it on the forums).
I flashed and still couldn't boot at first. I tried restarting a lot of times, until it got on the "Retry" or "Power off" option. I let the phone sit on this screen until it shut itself off. After tried booting up a few more times until it finally did.
I was not plugged in during this.
I'm not going near that october patch ever again.
Hello everyone,
I'm using mi A2 (64gb). It is rooted and was running on Resurrection Remix 8.6.2. Somedays earlier, I let my phone idle, suddenly it starts rebooting, just like bootlooping. After seeing that I booted in recovery and wiped dalvik and cache then rebooted and the phone rebooted in system successfully. But then I noticed the power menu appearing continuously on the home screen, I tried to dismiss it but it rebooted again and so on. From then, only the splash screen appeared for 8 seconds and it reboots again. I can boot into recovery or fastboot but only for 2-3 seconds then it reboots.
I've searched on the internet and was flashing firmware manually from fastboot but accidentally, I flashed an image file in a wrong location and the phone screen turned off and nothing appeared. Then I found that it had entered in EDL mode. but still it is rebooting and I can't flash firmware from mi flashing tool as fastboot wasn't working.
This is the problem of my phone. A help would be amazing! Thank you!
Ps. I'm new here and it is my first post so if anything is wrong. I beg your pardon and sorry for my bad English.

Try shorting testpoint in motherboard then enter EDL mode,
Then use mi flash tool.need to remove battery first.
How? Watch youtube, for mi6x. Mi 6x = a2, sort of.
~yes, you need to remove/open the phone.

U said rebooting even in edl, if not. Dont. Just make sure you have enough battery juice.

i have a similar issue, phone reboots when flashing reached vendor b and goes into bootloop, anybody ?
Hi !
Mi cellphone worked well for one month and yesterday began restarting by itself, I tought It was a problem with the button ON; but today it gets worst, the phone doesn't restart to the menu home, it just keeps turning on in "Bison" and then it turns off, and again "bison" and turns off, here a link
I can't use the recovery mode because the times i reached it the phone turns off; there's a mode to block phone's turning off? maybe using some buttons?
Please I beg you, help.
i have got the same problem with my bison also ,on one month it was work properly bt nw restart it self every 4 seconds
can you give more information? Did you unlock the bootloader? Did you install another OS? Did you use Magisk?
Or was it a stock image with locked bootloader? And failed on its own? Its possible there was an OTA update but I cant tell with the info you supplied.
Hi, I just update the software from the provider (i think is a OTA update, a normal update).... and then the problem appears, it takes a few of days to show the bootloop; i dont do anything else.
Now im triying to flashing the rom but it's SO ****ing difficult, because the phone restarts always, but not completely.
I tried to use the default recovery mode, but the phone restarts...
I was thinking about some file to block the bootloop while flashing? it that possible?
Using the flash i just do download, and to finish the process it left just 3 files: supersu, cache and userdata, but it restaaaaarts :C ... i tried the option "upgrade firmware" but formating stops at 88% XD
I was thinking about a full format, it could be worse, no?

YES, after that loop of boot problem,it came in normal after flash by SP flash(firmware upgrage),, then problem arose again,flash secondly by SP flash(formart all and download),this time it start normal but with another problem(TEE and google unwriten key,lost of IMEIs),i decide unlock bootloader and root it by magisk (follows umidigi comunity tutorial)bt all fail,it remain loop of booting it take more than 1mins show bison last log before start and shotdown again,,,off botton respond very slow on power on.
My Bison had this same infinite boot loop problem and I found out that the problem is in the short-circuited power switch. You have to open it and disconnect the flat from the side buttons to test
Today I left my phone in a cab and got it back in the evening. But after I got my phone it was stuck in a boot loop (after force restart - power button press and hold - it will go to battery icon and automatically restart after a few minutes and again goes to battery icon). Please see the video to understand the boot loop. Unfortunately, Developer options of the phone were not enabled.
Can boot to recovery but can boot to fastboot.
Can you please help me to boot my phone back to normal or sideload a ROM via adb.
tia
Was able to fix the issue. Followed below steps,
1. Kept phone until the battery fully drains
2. Plugged into the charger and charged the phone up to around 65% while the phone is switched off.
3. Switched on the phone when the cable is disconnected.
4. This time the phone was booted to recovery. No battery logo anymore
5. From recovery, rebooted the phone. But again it was booted to recovery.
6. Wiped all data and rebooted.
7. Phone was booted to MIUI os but had to set up the phone again from the beginning.

Same problem bro, did u resolve it???
I think your battery is empty. Leave it on power for a while and check if its charging. Maybe the charginglevel is too low for booting up.

I hope it was that simple ..it seems probably like a bad update. My gfs phone did the similar today
The digitizer stopped working, I force reset the phone and boom ..recovery mode - Trying everything but it doesn't work. Wipe surely would work but she has pictures and videos so I'm trying to avoid that. Plug it to charging but she remembers it had like 75% of battery ...geez (hoping for a miracle)
EDIT: Probably this happen from the bad xiaomi update, anyway I did wipe the data and as expected it work without an issue, I'll unlock this phone and ditch MIUI (I mean I did it to my phone Xiaomi Mi Mix 2S from day 1 - I hate miui) ..now my gf has a reason to hate it too
A factory reset could be painful, since you would lose everything on the device. I saw a guy tap all over the back of the phone with two fingers, and boom! The Redmi Note 10 Pro boot normally! I tried it on a friend's phone, and it worked.
Hello,I had a kind of a similar thing.
I left my phone to charge and when I was back it seems to be stuck in a boot loop(MIUI14)
Well,I tried to force restart but the same.
Before I go to recovery mode,accidently,I putted the phone in fastboot mode.I restarted it in the try to go to recovery mode but the phone started normally.After boot,it's shows an update compete message,so te problem was from an android security path update whatever.

I have important apps on the phone and I wasnt thinking about a factory reset anyway but hopefully it worked in that way
