I alredy did that. It doesn't work. It stucks in android is upgrading or loading apps. I don't remember exactly what it says, but it's something like that. Do you have any idea for what may be happening? Thanks for your help!
EDIT: It's freeze and reboots as such as the image

I had this problem too and there is a solution for this boot loop. Downgrading lollipop to KK causes this loops. Search as "SM-N910A baseband unknown SOLUTION" on google and you'll find the solution.

solution
hi, can you check your imei / baseband when you're on kitkat? (you have to do that very fast because your phone restarts every couple of minutes)
if your imei is null and baseband unknown, you can follow instructions on my thread here http://forum.xda-developers.com/note-4-att/help/baseband-ok-imei-unknown-efs-folder-t3156309
it will wipe the efs files, baseband will fixed, but imei still unknown.
i'm still stuck on the imei, but so far, the phone's bootloop will be fixed, no more auto restarts :fingers-crossed:

GNX-GSM randomly rebooting @stock JB

Hi Guys,
A friend got a problem with his Google Nexus GSM. He has 4.2.1 takju on his Phone (original there was the yakjuwx build installed), but he is having this problem since 4.1.1 yakjuwx. It randomly restarts. Not reproduceable. After the restart the accu level droped down very hard. The repair service said that there is no hardware defect so they just reinstalled the stock rom. What schould he do now ? Is this a common problem ?
May this screenshot will help you to understand what I mean.
EDIT1: also tested with a second original accu

Need Help! N7100: No Service - IMEI: Null

Hey Guys, this is the first time this has happened. I was using my Note 2 and it got really slow (im on Hawkish Rom | Perseus Kernel) and i decided to reboot it. On reboot the device booted and got to the "Samsung" Logo and was stuck there! i rebooted a few times more, and pulled the battery but it was still the same problem! So i decided to flash my ROM again, now the phone successfully boots to the OS, BUT it keeps saying: com.android.phone has stopped! I tried to go into Settings and check if my IMEI number is okay but when i click on "Status" under "About" settings just crashes. I opened up the Phone App and hit *#06# and it says IMEI: NULL. My WiFi works fine, but i cant get any signal. I have always made frequent backups of my EFS partition. How do i fix this issue? As i have a lot of business calls i am missing right now! Thanks!
ok. first things first if IMEI is lost (happened to me once) Just try to recover EFS partition using your recovery (TWRP o CWM) just search the option.
the one thing that worked for me it was flashing a new version of a Rom I was using android revolution and it also got laggy so I reinstalled and...I lost my IMEI (like you) then I just flash wanamlite (G1 Modem) and i got back my imei .
hope it works.
(there is also a thread in the development section)

Hi,
I was flashing a custom ROM and my IEMI became null.
I tried flashing official 4.3 ROM of my carrier but that did not solve the problem.
I have not done backup to EFS and thus I cannot use that option.
Would you please help me fix this?
Thanks

Strange things happen to my i9195... suddenly out of the blue,wifi won't turn on neither from quick settings panel nor the settings itself...
Everything else works as it should(data,bluetooth,airplane,gps,sound etc) but the wifi setting tries to turn on but immediately turns of. anyone had this problem?
and more important... a solution??????????
Which rom are you on? You could try reflashing a rom to clear any possible software issues
yes try reflash rom

thanks guys for your replies...
i was on stock rooted xxuamf4, i flashed both xxuamh3 and xxuamg8 (these two i had already downloaded) but problem remained. just to eliminate software issue , as a last resort i flashed CM 10.1.3 and magically my device was fully functional again( by the way ..:good: to CM...).
So WTF? i 'll try later to flash a stock non rooted fw and see what will happen...
p.s : anyone know how to change baseband? in my sgs3 mini i used to flash different modem for that. what works for this device?
p.s 2 : thanks again for your time guys!:good:
flashing back stock firmware , problem reappeared! it seems something has to do with knox , because every time i try to open wifi a toasted notification appears "prevention information... the device as detected...bla...bla...bla"
the thing is that if i root my phone and completely delete knox,knox agent,store and container agent, the notification stops but the wifi setting still cannot be enable.
any ideas????

Back to report that re-rooting with arco's method but with rootkit v2 (that includes kernel) seems to solve the issue! the steps i follow was :
1) gain root
2) install cwm recovery
3) with es explorer delete knox store,knox agent, container agent (both apk and odex files)
4) reboot to cwm recovery
5) clear cache and davlik cache
6) reboot and RESURRECTION!!!:good:

i think it's a kernel related issue. But first in order to eliminated hardware problem possibility, try to flash a cm rom. If your wifi and bluetooth works then you can be sure it's not a hardware failure. in my case flashing a different kernel solved the issue.
p.s : if you find a way to change baseband version ,please share the way!!!

you need flash same version Kernal file, example: when you finished flash MH2 stock firmware, if wifi shotdown, just flash MH2's Kernal file, file size around 7MB

I have problem whith my s4 mini.. I9192 dual sim
Baseband : Nd1
When i want to connectt to wifi i enter password.. As soon as i hit the connectt button wifi signal will desappear... I updated the frameware but no sucsess...
How to solve?
Is it hardware issue?
Same problem for me (1st post): new i9195 with latest XXUCNK1, never flashed before,
install twrp and make a backup, install CM-12.1 and CM-13 without any issue,
After restore to KK using my twrp backup I can't turn on wifi,
solution was to flash Modem_I9195XXUCNK1.tar from modem thread.
I notice that twrp doesn't restore previous modem I update to XXUCOL1

[D855 32 GB] Reboot problems (brick or hardware defect?)

Hello guys,
I managed again to brick my phone.
I flashed Fulmics as I wanted to swap from those not fully stable nougat roms. Well, I have no idea what caused my problem - Fulmics run without prolbems for a 2 or 3 days including xposed etc.
Then today I changed my ChromePie options and that's when the reboots began. I don't know if this the real cause was though.
So I tried to flash another rom but always got random reboot even in recovery after few minutes/seconds. So I went all the way back to stock rom (4.4.2) with LG Flash tool - which worked after a few tries. Then I installed MM rom via .kdz file and flash tool 2014, which also worked after a few more tries. But then the reboots started again. Can't say if the 4.4.2 rom was without boots because I updated to 6.0 quite quickly.
The strange thing is that after some reboots phone won't boot again and I have to take and leave out the battery for some time to boot the phone again.
Any solutions for my problems?
Best regards
..bumped into the same 1/2 year ago. Didn't want to put to much effort so,..went to stock and back, worked for me.
Good luck.

Which stock and how did you go back?
As mentioned I already went back to stock but the issue kept occuring.
Hi, got the same problem with my G3
wi fi and bluetooth didn't work and phone loop rebooted
Here below the steps I followed to solve
1) First attempt (didn't solve): had cloudy rom, got back to stock official but still rebooting, tried fulmics and other rom but problem persisted.
2) second attempt (didn't solve): went back to stock and changed battery (found somewhere in internet), now I have a brand new battery but a phone still loop rebooting
3) third attempt (SOLVED): found that the wi-fi / bluetooth chip (one for both) copuld have unwelded and solved so (it appears I can't post outside link, delete spaces to have the correct link):
youtube .com / watch?v=1zWpzYh2DPI&t=15s"
youtube .com/ watch?v=6_0jzp65eLY&t=256s
Now i'm on fulmics and no more loop reboot
Hope you can solve
[sorry for my english]

used flashtool
have to say restoring and/or flashing isn't always that stable. I've experienced it sometimes needs a 2nd try.
Hopefully it isn't a hardware issue in your case.
So I tried all of oyur suggestions but nothing seems to work.
On the contrary I ended up in a status where I can't even flash a new firmware.
In LG Flash Tool 1.8.1 I get the error
"Donwload Fail!!!"
PID: NULL
IMEI: NULL

DLL: D855
BIN: LGD855AT.....

In LG Flash Tool 2014 (flashing MM with kdz file) phone shuts down in middle of process.
But I can still access Download Mode.
No more ideas?
I really think I finally broke my phone... But the fact that I can still access download mode keeps my hopes up.
So, after 2 months I just tried to reawaken my phone. Still the exact same problem. It just keeps shutting down aber some while, but just when I start flashing something. If it stays connected to computer whitout doing anything it can stay on for like ever.
Can anyone confirm that this could be a hardware defect?

SM G928T Update problems

Hello Guys,
This is my first time posting on xda forums,
I rooted my Sm g92t from t mobile,
everything was working fine until i tripped the oem unlock,
restarted the device only to be met with frp block.
searched online and tried to fix it, got it to work
but ended up with unknown baseband and imei null.
Things i've tried
1. Run several roms, all stock
2. tried to use z3x tool to fix but no luck,
3. tried restoring efs backup, no luck since i didnt know much about efs folder by then.
One funny thing is that, whenever i run a new rom,
installing system update which comes up the rom has finished loading doesn't
reach 100%, it gets to 32% and switches to erasing and continues to boot.
I've lost hope, no T-mobile or Samsung service centre close by, i really need help.

IDENTICAL Problem. Flashing original ROM T-Mobile QE1 and after reboot it goes to 32% and then resets and gets stock in T-Mobile.
I tried few things nothing is working. I have Z3X box but I am not sure how to pinpoint problem.
Anyone can suggest something >?<
Hey,

Bootloop
How did you fix it with the combination of roms
