G935S no data connection after custom ROM installed - Samsung Galaxy S7 Edge Questions and Answers

I have SM-G935S (SKTelecom Korea) and have been trying to improve battery life by using custom ROM. The installation is a success, but it makes my phone cannot use mobile data connection. I have been trying RENOVATE 4.0, SupermanROM, and KingROM but all have the same result. Are my device not compatible with those ROM or any mistake and fix that you can point it out to me? I'll be thankful for your help.

If the imei still intact, there's hope. Try flashing original rom. If not, service center is your only option.

Try updating Boot loader and Modem before installing the recent custom ROMs. Or use ROMs that have the Auto-Bootloader and Modem update. Check APN settings for Your network.

I have the same issue but for a G935F
Did you solve the problem?

It happened to me also. I have g935f. Only thing that works for me is to install csc after installing the rom. So first install rom then let it boot. after boot before settings go back to recovery and then install your csc and then boot up and do your settings. Good luck.

[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

I have done a clean flash of my KK TW V29 without issue....
first I have made a FULL wipe include internal storage and flash stock NI4 rom but without any changes
someone got an idea???

Please message me the following details from the sticker inside the device under the battery, so I can grab the Service files from samsung for you!
I've flashed OB1 with odin and flash back after 2 weeks NI4 and the last I try was this N9005XXUFNG2_N9005OXXFNG3_XEF (Open France) (No-wipe)
the flash goes well but doesn't change my BL and modem, before that I was with NI4 BL and NI3 modem and now still with that
I use sosh carrier (orange) in france
will send you the details from sticker
@rayman95 This is what i have found out!!! From my understanding, You took the Lollipop bootloader when you installed the OC1 Package. if you want to completely restore to "Earlier Version", WHICH this may not be possible due to a SAMSUNG new coding issue, You would need to have the complete 4 Files software to repair your device.... As well as using all the following checkboxes in ODIN:
Auto-Reboot
Re-Partition
F. Reset Time
NAND Erase ALL
Phone Bootloader Update
I Attempted to download your files for the device, but Kies will Not "Initialize" for download, and it will give you an Error if you plug the device into Kies3 i believe because you device is ROMMed.
IF you want to try Kies to restore AND it begins "DOWNLOADING", You can copy the Tmp****.tmp.zip that is created when the progress indicator hits 85% in Kies.
The File location on Win7 is "C:\Users\*Your Screen Name HERE*\AppData\Local\Temp"
If you Have the 4 Part file for NI2, try flashing in ODIN wioth the Above Checkboxes selected!!
Kies don t let me dl any files and gave me some error but don't remember exactly what... but not important because you give me good files.....after that I hope flashing again cm12.1.....
Thank so again chief....

Note 4 n610f bricked?

Hi all, im really hoping someone can help, and that what ive done is reversible.
After rooting I tried installing the alliance rom (lollipop) on my n610f, i got a boot loop so restored the backup rom using CWM without any problems, i read on the alliance rom page that id need a different bootloader and modem, i got what i thought were the correct one and put them on using odin, did a wipe and tried again, same bootloop. Except this time when i restore the backup rom i still have the same boot loop.
If anyone has a fix for this id be eternally grateful.
Fixed it by flashing N910FXXU1B OB4 [Lollipop 5.0.1] bootloader and modem
What did you flash? Modem or bootloader..? I think the best solution is, flash stock firmware via odin, then try again.

Galaxy S4 (GT-i9500) Major problem

Hello everyone. I used Albe95 N5+S6 Port rom for my GT-i9500 and it worked flawlessly. I had TWRP recovery. After a lot of using I thought to re-flash the rom and start using it new, so I reinstalled the Rom file on my external SD card and flashed the rom using TWRP recovery and it was a success, but then I noticed I accidentally backed up some things which I didn't wanted to I re-flashed the Rom again, but this time when I (in recovery mode) wiped the data, I chose "Advanced Wipe" or "Advanced Reset" (It was something like that I don't exactly remember. So after that I reflashed the rom and when I had to press "Reboot" a message appeared above saying "Looks like super user is not installed in your phone. Do you wish to install it?" I said Yes and the screen went blank. I tried to reboot but It didn't. I removed the battery and then put it back again and tried to get into recovvery but recovery seemed to be lost and I ended up in Samsung's own factory mode where we have options like reboot, flash using external sd card, flash using adb, enable cp logging and etc. I tried to flash back everything but nothing works. Tried Odin and tried flashing custom firmware but it fails. If I reboot Samsung Galaxy S4 GT-i9500 comes on screen and then it goes blank no boot animation or anything like that. Please help me, Your help will be highly appreciated
I used advanced wipe many times before, I'm pretty sure something else caused your dilema.
And most Odin fail messages are caused by the USB cable, PC USB ports (back ports are recommended) and Windows version.
So what should I do now?
If the problems are caused by the above mentioned, you should obviously try to change things up.
It appears that your phone is in soft-brick.
Also, you lost your TWRP.
Check your bootloader version and install the stock firmware via odin. (If you still fail in odin, As GDreaper pointed out, odin fail could cause by usb cable, port and windows version so you need to keep changing until it works)
Root the phone. Reinstall the TWRP.
Then flash the custom rom again. When you install the custom rom please follow the cooker (custom rom maker) instructions on wiping.
Thanks for your comment. I'm kind of a noob, how do I check bootloader version? and how will I know after checking my bootloader version which stock firmware to install?
Bootloader has nothing to do with it.
If you flash a stock firmware, the Bootloader will also be updated to whatever Bootloader the download firmware has.
The only situation where the Bootloader would matter is if you try to go from lollipop to kitkat, in which case it will fail.
Thank you. My device is back now.
I am glad to hear that your problem is solved.
When I was on kit-kat, I did not check my bootloader version and flash the stock firmware with older version of bootloader which tripped the knox counter on my i 9500. That was why I said to check the bootloader version before installing the stock firmware. You can use app like phone info to see the bootloader info. Then install the firmware with the same or newer bootloader.
I recomend to Update drivers, Windows, Bootloader install Samsung Kies and Install TWRP again, After stock

Wifi, bluetooth and Mobile data not working N9005 LTE model

Hi,
Installed a Custom Rom Cm14.1 in my N9005 LTE version. After Some time i prefer restoring it to stock firmware. So I thought of restoring the TWRP backup file. Unfortunately, while restoring TWRP showed some error. Modem file not present ( not the exact error words).
Because of the error in performing a restore. I installed LineageOS. But the wifi, bluetooth and Mobile data is not working. Then I tried installing many stock firmwares of different countries downloaded from Sammobile, updato, etc but no use.
I tried downgrading my phone to Kitkat 4.4.2 and then upgrading it to Lollipop via Kies. But still wifi bluetooth and Mobile data is not working.
Please help me. Wifi and bluetooth is greyed out.
I also installed the "wifi and bluetooth fix v2.55 s5.zip" but no use.
Is there any other way. Please help.
First check your IMEI is correct .
Yes. IMEI number is correct.
Anybody to solve N9005 wifi bluetooth problem? Waiting for expert's advice. Please help.
Will restore TWRP file of stock Rom help in getting the WIFI bluetooth and Mobile data working?
If yes, can somebody upload the RESTORATION TWRP FILE (backup file) of N9005 LTE version.
Thanks in advance.
Depends upon what problem is but yes worth flashing stock rom via Odin .
Was Odin successful in flashing a stock ROM? If not, post the Odin log errors.
Thanks for the reply. ODIN stock Rom flash was successful. No problem in Odin flashing. I tried different country stockroms, No problem in Odin flashing. But the problem persists.
What is your CSC ?
DXUGBOK3
Any help?
You need a service repair .
You flashed the latest stock ROM in Odin? Tried flashing with a pit file?
Yes flashed the latest stock ROM with ODIN. But England STOCK ROM. Pit file too.
