I've been using the same ROM, TWRP recovery for 5 years without issues, but today, I tried to restart the phone and it seem to bootloop in the bootloader Animation, then I tried to soft reset with (volume down+power)button, then it started bootloop with recovery, the phone name shows for more than 2 minutes and then it shows TWRP loading page, then it loads for 5 seconds and there is no touch working in it, power button worked to lock it but after 5 seconds of no response, screen turned black and the bootloop started all over, I can go to download mode with (volume down+Bixby+power)button and return to the bootloop .
(it has a lot of essential files for my college and android development related data, not backed up)
Device: Samsung galaxy note 8
Model: SM-N950F(greatlte)
Root: SuperSU
Recovery: TWRP 3.1.1-0
Update(1): I got access to internal storage from TWRP, but the recovery doesn't stay, it stays for 5 seconds and goes back to loop, went to repair shop they said it's neither Buttons short issue nor battery, it's the RAM or something inside the motherboard. But now if the motherboard is damaged, how can pc still detect internal storage normally for 5 seconds in TWRP, I didn't flash the same version TWRP again because I really think it would revoke the internal storage access. Is that true?
Thanks for the support

This model has a card slot, so by backing up in twrp to external memory, you should have all the data you need to recover. Because for what other purpose to do a backup in twrp to internal memory?
If you didn't backup in twrp, your only hope is to replace the battery with a working one and try to boot.

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.

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.

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.

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)
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.

Dear All Respected Professionals,
My Samsung Note 8 SM-N950F Android 8.0 stopped booting all of a sudden. No software update, no modification, nothing. It was working perfectly, I restarted phone and it won't start again.
When I try to boot it stays stuck at boot logo (SAMSUNG logo) for around 5 minutes and then automatically restarts. It gets quite hot.
I can access via ADB while it stays in bootloop. I exported logcat. I'll upload if it may help.
I have around 2.2 GB free out of 64 GB internal storage.
Never rooted.
However, it seems like Internal Storage doesn't get mounted. I can’t access /sdcard or /storage/emulated/0
As much as I remember, I had "Allow OEM Unlock" enabled. I tried to flash TWRP via Odin in Download mode, but it fails.
I'm looking to
1. Revert phone to working state without formatting
2. If 1 is not possible, I want to at least make complete backup, something like nandroid to backup WhatsApp data and other stuff.
Note: I want to recover data from my phone. It has lots of important data. I don't want to simply format it.
Device: Samsung Note 8 SM-N950F
ROM: Stock Android 8.0
Never rooted
I can boot into Recover and Download mode.
This is my first post here. If any more details are needed please ask and I'll provide.
Kind people here please help me fix my only daily driver???

My Samsung Note 8 SM-N950F Android 8.0 stopped booting all of a sudden. No software update, no modification, nothing. It was working perfectly, I restarted phone and it won't start again.
When I try to boot it stays stuck at boot logo (SAMSUNG logo) for around 5 minutes and then automatically restarts. It gets quite hot.
I can access via ADB while it stays in bootloop. I exported logcat. I'll upload if it may help.
I have around 2.2 GB free out of 64 GB internal storage.
Never rooted.
However, it seems like Internal Storage doesn't get mounted. I can’t access /sdcard or /storage/emulated/0
As much as I remember, I had "Allow OEM Unlock" enabled. I tried to flash TWRP via Odin in Download mode, but it fails.
I'm looking to
1. Revert phone to working state without formatting
2. If 1 is not possible, I want to at least make complete backup, something like nandroid to backup WhatsApp data and other stuff.
Note: I want to recover data from my phone. It has lots of important data. I don't want to simply format it.
Device: Samsung Note 8 SM-N950F
ROM: Stock Android 8.0
Never rooted
I can boot into Recover and Download mode.
This is my first post here. If any more details are needed please ask and I'll provide.
Kind people here please help me fix my only daily driver

Trying following below steps..
1. First try to force restart device by pressing Volume down + Power key for 7 to 10 sec. It will fix system crash issues
2. Go to recovery mode and try to wife cache partition, ONLY WIPE CACHE PARTITION. DO NOT WIPE DATA/FACTORY RESET.
3. Try to boot device in safe mode, Press and hold volume down + power button, When you see Samsung then release Power button but keep holding volume down button until home screen.
Let me know results...
im having similar problems,
any results?
No matter what 9 out of 10 times I can no longer access TWRP recovery and Odin Download mode.
I'm currently on GA Lineage 7.1.2, rooted G900V. I have magisk 20.3 installed.
I've been having to change roms android 7.1-10 constantantly over the past couple years due to instability. Today the rom I was on I could not close the screen manually with power button otherwise the advanced power options would show. It's a bug!
Now all of a sudden after doing a full wipe and installing another rom I went to back it up and got the maintence boot mode rather than TWRP. I have already done factory resets, flashed other roms, re-flashed TWRP and my firmware. All of this several times over!
When I do mange to get TWRP I do wipe everything and restore backups of roms. Sometimes in download mode it wont stay and within a few seconds it bootloops into maintence mode.
I have no idea why this is happening again but now it seems it might be permeanent? Ive seen this maintence boot mode thing before but switching to another rom and or getting rid of bad modules stopped it. But not anymore.
Any ideas what is causing this and what can I do? Is my S5 done for? I guess at this moment I should stay on the buggy rom I was trying to get rid of until I can do regular backups again.

Well a bad power button could explain all 3 problems.
Or are you saying that even when using the advanced Power menu it will not reboot in Recovery or Download mode?

That never happened on my S5 G900M. I'm curious: could take a photo of it using an other device and post it here please?
Using this XDA site search: site:forum.xda-developers.com/ sm-g900v maintenance mode you can find other G900V users with a similar problem.
One user posted this:
I ONLY
GET "Maintenance Mode Recovery Menu" Which has 3 options
1 Normal Boot
2 Factory Reset
3 Safe mode Boot
But Sadly and STRANGELY I CANNOT GET THEM TO WORK EITHER!!!

A troubleshooting step could be to flash the most recent stock Samsung for your G900V which will re-lock the bootloader, test thoroughly to make sure it works properly then unlock the bootloader following one the numerous threads on XDA about it.
FWIW my Galaxy S5 G900M LineageOS 17.1 build 2020-11-29 + Open GApps Pico build 2020-11-05 + Magisk 21.0 + Magisk Manager 8.0.3 + TWRP 3.4.0 recovery is running smoothly without any major bugs.

Sorry for late reply I been busy. So the problems are happening again off and on. I'm going to have to switch roms again because mine keeps soft rebooting itself and dropping SIM card at times.
Next time I get maintenance boot screen i'll try to take a picture of it. The thing is from the restart menu I have the option to boot into recovery. When I do it only sometimes goes into TWRP otherwise goes into the maintenance boot mode and I have seconds to make a choice Boot normal, safe mode and factory reset. None of which options work. Within seconds my phone boots itself. I have the same issue in download mode if i'm able to get into it within seconds reboots itself. So it's very hard to do anything with ODIN. I've re-flashed twrp and my firmware a few times but it takes hours sometimes to be able to due to the self rebooting phone. There is also the problem of when I power off the phone in menu options it shuts off then powers itself back on again. I may have a bad power button its been a couple years that I can remember changing it. But it broke to where I couldnt power off my phone. When trying to lock the phone the reset menu pops up sometimes other times it locks phone as it should. It would be a ton of work for me to switch to a stock rom and do all that crap over again. I mean I wasnt having this problem this constant until recently.
I'm staying on 7.1.2 because bluetooth and music are working. I was on 8.1+ bluetooth would always drop and music would stop working in background due to how background foreground processes changed after 7.1.2. Also the camera file location is messed up and not in DCIM it's located in a lineage file. Whenever I take pictures they are auto uploaded into my dropbox. It doesnt work on newer android versions after 8.1. I have the G900V Verizon maybe thats why i'm having all these problems. I know for sure the No sim is one of them on this device.
I dont plan to buy a new phone until next year and it will be a 5G one. It's too early to invest in one at this time since 5G is just slowly rolling out.
@curiousrom here are two photos of the S5 booting into recovery / maintence boot mode.

Thanks for the photos.
So it seems it's a Bootloader Maintenance Mode, not recovery.
The first splash screen is the bootloader's which is named Aboot in the S5. See the attachments.
You installed a custom bootloader to unlock your S5 G900V & that's probably why it's acting up.
Ask in S5 G900V unlocking threads & includes those photos.

Odd because I really dont have this problem often and yes that was the only way to unlock the bootloader on 6.0.1. Anyhow I ordered a new power button should arrive soon. That might help with it being sensitive it does look a bit pushed in. I noticed it seems to not boot into TWRP if I choose to go to advanced restart menu and choose to boot into recovery. When I manually do it after powering off i'm not having the problem. So maybe it's a bug with all the ROMs out there when choosing recovery from advanced restart menu options.
