Just press the thanks button

If you do not like flash custom kernel and if you like official status you must install cwm or twrp recovery and you must clear system data and cache . And reflash firmware. If you wifi doesnt turn on again You must flash stock rom again. And you see every thing is normal and pDa and modem version is true device status is official

1. I recommend u do a FACTORY RESET (remember make a backup of ur data folders and SMS before do this process). You will recover the sound maybe. If that no works continue with next step.
2. Full wipe (You can do this in CUSTOM RECOVERY or STOCK RECOVERY).
3. Flash again android 4.4.2 stock rom :highfive:.

[Q] lost root and can't get it back

Hi all,
I rooted my smg900f two days ago and flashed a recovery, everything went fine, I tried a couple of custom rom and at some point I noticed that I didn't have root access anymore (checked with root checker). I launched towelroot again, and now it says that my device is not supported yet. Does anybody encountered the same issue ?

I have clockwork recovery, I had Omega ROM running on my phone (maybe at this moment I already lost root but I only noticed it after), I tried to flash this mod, it didn't work so after a few tries I full wiped my phone and insalled Omega 8.0 again. Then I noticed I lost root access when trying to open some apps.
I also flashed the bootloader for SMG900F featured in the Omega rom thread
That's about it

Then i suggest you flash a stock rom, factory reset and root/flash custom recovery from scratch. Its seems some files are messed up that prevents you to root. Backup important files to the pc/sdcard first. That is what i would do at least

Good luck mate. After the flash and factory reset flash a custom recovery and then the superSU.zip and you`re rooted.

There should be a folder on the sdcard named Clockworkmod with the backup, save it to the sdcard before you factory reset. No a backup can`t be flashed with Odin, only in recovery

Did you flash a stock rom with Odin or flash a custom rom in 3rd recovery? Just do a data factory reset in recovery, pull the battery and wait 20 seconds and flash a stock rom with Odin.

- you should be on kitkat stock rom.. the recommended firmware is NH6 and NK1 base
- root your phone
- then install recovery like cwm 6.0.5.1 or philz 6.49.0. you can find it on grand 2 thread easily
- after that install S6 styled S5 port. before install. make sure youdo this :
1. wipe data,cache, and dalvik. wipe dalvik can be find in advanced option
2. format system and boot in mount and storage option
3. then flash the rom
4. then aroma installer should be begin. there 2 option here
- wipe external sd card : this will wipe all your external sd card
- no wipe
if you dont want your data in ext gone.. dont choose wipe ext sd card !
instead use no wipe
5. oh yeah after that flash deds kernel v2.0 in kernel section of grand 2 thread. if you already download it. just flash it..
the reason flash deds kernel because it will fix the wifi and xposed installer issue
- and its finished. just reboot your phone now.. wait 5 minute and yay.. :laugh:
if i help. please hit thanks button okay

hmm maybe you should do this
- flash stock rom nk1 again and root it again
- after root your phone, reboot .and you will see supersu app. open it.then you will see knox bootloader. choose disable bootloader. then now it update binary from supersu. choose normal .dont use twrp/cwm option. reboot again. and now download busybox in play store. after that install the busybox
- then flash recovery.. and then see the instruction of flashing rom in my previous post
note : dont flash deds kernel v2.3e... it will brick your phone... flash deds kernel v2.0
please tell me if it works or not
I opened superu after reboot by it is showing nth in hw to disable bootloader

Yeah ofc,just download odin for your phone,find stock rom here http://live.samsung-updates.com/ download, go to odin check pda etc (i think you know how to flash rom in odin) then go download mode and flash. After it you have clear phone, stock rom , no recovery , no root.

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
