KIES running in background as process?
Tried another USB cable?
Tried to use another USB slot?
In order to turn it off ... did you try to push Powerbutton and hold it pressed until re-boot?
BTW what did you do to get into this situation?

Try flashing a Stock ROM with ODIN
PS: Give more informations please
hi
​Thank you for your quick reply. Fortunately i've resolved the issue. Indeed i've flashed a stock rooted rom(XXBMEA) and it worked. Unfortunately my goal was to flash the new Omega v5.0 rom but it looks like i cant flash the new TWRP 2.5.0 kernel. I can flash it successfuly but nothing happens. Can you please help me in this sittuation. At this momment Im using the XXBMEA stock rooted rom with the wifi and data fully working. So i think i could flash at any momment the Omega rom if i could flash a working TWRP or any other way if u know. Please help me.

[Q] n900 stuck on Samsung logo

Hi guys I've been facing this problem for a few months now. Hope someone can help. I am on vn rom v14. While on this rom I had flashed the clear warranty zip to reset my knox counter to 0. I was curious to see if it would work. Therafter I decided to flash stock firmware. After the flash I was stuck at the boot logo. So then I booted into stock recovery and wiped data factory reset, wipe cache and wiped dalvik cache. The phone then boots up however it doesn't receive any network signal. It can only connect to wifi. Base brand version and imei are also lost. The only solution that I found was to flash the vn rom again and everything is fixed. I seem to be stuck on vn rom as this is the only rom that picks up signal. Tried many other roms and have the same problem. Eventually I have to return to vn rom to use my phone. Can somebody please help me.
After you flash your stock firmware (you lose your imei )
You should install this zip file from twrp or cwm

Thank u so much il try that.

Help!!! Bootloop with custom roms

At the moment have stock 5.0.1 rom for SM-N910F.
have rooted and installed twrp through odin but every time I try and install a custom rom, it installs but it bootloop. And I mean every rom. Tried installing twrp through flashify and as a zip file and both of those won't boot the phone up at all. It will just go straight to download mode.
I am fresh out of ideas and any help would be appreciated.
I have been flashing for years so I know the steps to successfully flash custom roms but I have never faced this before.
you sure you got the right version for your phone, seems like a compatibility issue with your recovery/bootloader.

Yeah that's what I thought but it was for SM-N910F according to TWRP website and all the roms have been for that same version.

Flashing roms and getting bootloop

Hello guys I need a little help here in every time I flash marshmallow rom or nougat rom I got bootloop so after googling for an answer I found that the solution is by changing or updating the baseband version so I need you guys to give me a link for a modern baseband version and tech me how to flash the baseband version.
I know I am asking too much but I really love flashing those roms so please help me.
My baseband version is SM-G7102XXUBOE1
I am now using CM12.1
And I tried to flash stock firmware then flashing those roms but still Getting a bootloop.
Note: all lollipop roms work good (except blisspop Rom when I flash it I got bootloop so I extracted the cm12.1 boot.img then I flashed it so blisspop rom booted but Wifi, hotspot and ril didn't work.
Revert to stock ROM using Odin (use NAND erase all option). Then back to install CM13.

1.download NK1 firmwire from here
https://forum.xda-developers.com/galaxy-grand-2/general/stock-firmware-grand-2-google-drive-t2849501
2.Extract zip to get a .tar file
3.Download Odin.
4.Select AP and click on the .tar file you extracted
5.Factory format the phone,then take out battery for 8 sec(not so necessary ).Then switch off grand 2.Then hold vokume down+power button and click volume up when asked for confirmation
6.Attach the phone to PC and click on flash
7.After finishing,turn on mobile,complete first setup in stock ROM then install TWRP recovery on the device and install any ROMs. Your problem won't occur again
I have the same problem but i can still run my phone on boot but after some few seconds, it will reboot and then goes back to lock screen and then does it again. I flashed Ressurection Remix for Grand 2 btw

Baseband & IMEI unknown after flashing CM14 on SM-N910C

A few nights ago, I flashed CM14 with Nougat on my SM-N910C. Unfortunately, ever since the flash finished, my phone stopped reading any SIM cards. The baseband and IMEI both read "unknown" in the settings. Is there any way to return these? I'm okay with anything as long as it ends up making my phone usable again.
I'm not an expert at this, so please explain stuff your help is appreciated, thanks!
Bump! Please help me out!! Any tips appreciated

Did you made efs backup from twrp before flashing rom ?
If you have efs back up then restore it.
If not then Try flash stock 6.0.1 firmware via odin and do factory reset from stock recovery after flash.
