Flashing roms and getting bootloop - Galaxy Grand 2 Q&A, Help & Troubleshooting

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

Stock ROM Backup

Hi,
I have rooted and installed TWRP on my 910F Note4 as I was fed up waiting on the lollipop update rolling out. I am currently on 4.4.4 and have made a full backup using TWRP of the stock rom.
My intention was flashing the Cyanogen ROM and using that, but i now see on sammobile there is a stock 5.01 rom available. I have a few questions about this.
1. If I flash to Cyanogen can I still revert back to the stock rom 4.4.4 I have made a backup with? I read somewhere there might be problems as I was on KitKat then moved to lollipop(Cyanogen).
2. Can I flash the stock lollipop rom from within TWRP? Or do you have to do this via ODIN?
3. If I flash the Lollipop stock ROM with Odin I assume I will lose root and TWRP? So this would have to done again?
Guess I am asking what is the best way to proceed?
Thanks again
Paul

hi Paul,
1. i beleve to flash CM from kitkat you will need to install the lollipop bootloader first.
2. You have to flash the stock rom via Odin, you will keep all apps settings and files but you will lose root (you u can re root in 3 minutes)
Best thing you could do is flash the stock rom first with odin, see how that feels (IMO its good been using it for months now) and then root it and back it up and flash CM12 (you dont have to flash any boatloader at this point)

Ok tried to flash Stock O2 UK lollipop ROM via ODIN and got error message on screen. MD5 too big or something. Had to pull battery on phone. Had to then reflash TWRP. Got back into TWRP and tried to do a recovery of the backup I took but phone is stuck at Galaxy note 4 screen. It then shuts down and restarts and gets to the same screen again.
Do I try a different ROM? What can I do?
Thanks

I got it working by flashing the German non branded ROM... Got the error message again but then used a "All samsung recovery.tar" as stated on another post in here and it booted fine eventually... Now on Lollipop. Now time to flash with TWRP.... Again!!!
Please, i need help !
I need help, urgently !
My Note 4 SM-N910C does not work. I can enter the Recovery and the Download Mode. When attempting to install a Custom ROM gives me an error that says I have no data. In the internal memory I have 0mb.
I tried using odin, but I can not .. Salta error.
Someone who can make a backup of your phone (which is factory), leave me a link to download it? So I install the TWRP. Please.
They have another solution?
Thank you.:good:

[Q] Stock ROM .zip for SM-G530H or Solution for Odin Error

Hello all!
I did a small mistake with my brother in law's phone. I lost his System and thought "ok no prob... just need to flash the stock with ODIN".
Well... life kicked me in the nuts... every time that I try to flash the original ROM by Odin 3.7 or 3.9 or 3.10 I see an error (Failed (Auth)). I don't know how to solve.
I did flash MIUI with a lot of bugs, so he can use the phone but I'm feeling guilty. Since the ODIN flash is not working and CWM is working... I'm here to ask you for a favor. Does anyone has a Stock or almost stock ROM for the SM-G530H to share ?? Or maybe do you know how to solve the Odin problem? Which firmware to flash without error?
His phone is from TIM provider and we are from Brazil.
Thanks guys!
same problem
Hi i have the same problem is there any update on the issue
I thought we're not supposed to post our questions in general section?
Me too
Guys I have cm11 working good the only bug that he always forget WiFi ssid and I want to back to stock and my phone can't detected by Odin. I have philz touch and I have a semi solution
First of all I extracted the cm11.zip I take the folder. Meta-inf it contain the updater script
I extracted system.img.ext4 with ext4 extractor tool then I created a zip file that contain system folder and meta-inf and flashed it through philz and it worked but WiFi not working and sim too (in my case I need to flash modem.bin too)
Stock ROM 4.4.4

emotion revolution on note 4

Hi,
I want to install emotion revolution and I have some questions:
- I have a SM-N910F with android 5.1.1 and baseband N910FXXU1COH4 Kernel 3.10.89-emotion-TW-5.1.1-nigltly-r21 . TWRP is installed and device is rooted. Can I directly flash or should I flash modem or bootloader first?
- Is the note 5 port release also working or note 4 or is there a specific one (didn't find anything)
Sorry if my questions are stupid, I'm a little bit lost with the version numbers COI4 COH4...
thanks
in advance

firmware version numbers are really simple.
the higher the letter in the alphabet, the newer the version.
that's all there is to it.
so COI is newer than COH.
the Emotion rom topic should have a clear explanation of how to flash it all though.
i think they even added the bootloader and modem that you need.
and a note 5 port...of course that works on a note 4, that's why it's called a port

1. You must update BL and Modem, else it won't work. Both are available on their homepage, and they're the same as for Emotion Revolution r10.1
2. The Note 5 port is working on the N910F. Be aware though that the Note 5 port "features" stock Samsung colours, i.e. it's plain ugly (IMHO ). That's what's keeping me from flashing it atm. Emotion Revolution r10.1 has a more stock Android colour scheme (e.g. b/w toggles), which I find much more pleasant to the eyes than Touchwiz turquoise. But unlike r10.1, the Note 5 port has a working Theme Store (should have at least), so it's probably possible to theme the ROM to your liking.
Hi, I tried to flash modem and bl with the files on the site. I ended with an unknown baseband and the Phone powering off after 2 minutes... I used odin and put the bl file in the bl section and the cp file un the ap section and clicked start. Is this wrong?
I flashed a stock rom to get the Phone working Alain.

good question. I saw a video telling it must be put in AP. I tried again and put it in CP but this gives the same result, baseband unknown and mobile restarting after 1 min...
any suggestion?

Hard to tell. I'd try this:
1. Flash BL and modem via Odin
2. Boot into recovery (TWRP 2.8.7.0)
3. Wipe /dalvik cache, /data, /system, /cache
4. Flash Emotion rom.
If that fails, download a COI3 stock rom from SamMobile, flash it via Odin, then try again.
Ah, the sweet moment when your phone finally boots up and runs. I can't tell how many times im the past years I believed I had murdered my phone.

Hi,
thanks for the reply. I also installed phone info. After the flash from modem and boot loader, phone info displays the new BL but an empty CP...
I also tryed to flash the COI3 modem and bootloader found on alexndr ROM but with the same result
Do you think it is because I flashed COI3 Modem on a COH4 firmware? This means that flashing emotion will "repair" it?
COI3 Firmware is not availlable for Switzerland for the moment...

Flashing a custom rom won't repair your modem. You can try, of course, but I doubt that will fix it. If nothing helps, you can start from scratch, flash the older OH4 firmware with Odin, make sure everything's working, then update BL and Modem, and flash Emotion rom. I hope you've made a backup of all your stuff?

Hello @Leboboy19 ,
Can you try using Odin (newest version ) and flash the original stock rom that you had before messing around with custom rom. make sure to uncheck re-partition. you may have to flash the stock boot and stock recovery .img which you will find on shellbox firmwares.
If that does not work can you try flashing the twrp md5 for that device . let me know

Thanks for your message brother, you reminded me of the tab after giving up on it, after months of trying finally found a fix.
to anyone having this problem:
1. Download your latest stock
2. extract it and swap the recovery.img with a recovery.img from a combination file that matches your binary number
3. Enjoy Your Recovered Tablet or sell it like me:laugh:
