my galaxy s2 is GT-I9100. i saw a jellybean update is on kies so i did the update. However after i did the 4.2.1 update, i found out my CSC was changed! before the jellybean update, it was TGY(HongKong) after the updates, it changed to XSP(Singapore)...WTF.............
Also i cannot change the CSC anymore. i tried using CSC select to change my CSC, but it says "com.android.Precnfig not found on your device. Manual mode..." not only in phone, Kies also says my device is unable to do S/W upgrade or something.
BTW i haven't done any rooting. i don't know why after i did the jellybean update, it shows these kinds of problems.
please give me some solution or any feedback!
re-flash.
Sent from the little guy
changing csc code in jellybean requires root access.
i rooted and tried csc select but there is no csc to select from.
anybody know why?
Did you solve this problem?

Hey I just my Samsung galaxy s20 (SCG-01) is locked to the au network in japan (Blacklisted too I bought it second hand ), and I tried many ways to unlock it but nothing helped, So now i'm trying to install a different region firmware same model same specs the only difference is the region. My model - SCG01, The firmware I'm trying to install - SM-G981U. But when I try to install the firmware through Odin, it shows a message as a failed in red. When I click start in odin it takes around 3 seconds and the failed message is shown. My problem is why can't I install a different region firmware even thought all of the other specs are exactly same in my device, Please help. I'm using the latest version of odin as well
Hello everyone,
I need help with resurrecting the above phone model. After updating it via Samsung Switch, it 'magically' stopped receiving network recognition but it could sense the SIM card's network operator. I tried dialing some numbers and it said "Not registered on the network". I ran to the internet through various forums. I have been re-flashing STOCK ROM and i was getting PASS; still no good came out. I tried custom ROMs, same thing. NOW suddenly i got an efs/ failed to mount. How can i resurrect my baby? All i have about the phone is:
AP: G925FXXU6EVG4 (Build number) - NDR90M
CP: G925FXXU6ERF5 (Baseband version)
CSC: G925FXXU6EVG4 (Country version) - 02U
IMEI SV - 02
SN - RF8G610C1MN
The stock ROMs i have downloaded so far are:
1. Samfw.com_SM-G925F_O2U_G925FXXU6EVG4_fac.zip (stock ROM based on the last successful booting ROM; after updating via Samsung Switch)
2. Samfw.com_SM-G925F_O2U_G925FXXU6ERG1.zip
I have these in place:
- Samsung S6 Series EFS Backup Restore Tool v1.0 By Jamesjerss.exe (which i used prior; to get an efs.img before my phone got messed up (a 20Mb file was created). Is that the backed up EFS?
- Odin Odin3_v3.14.4
- CF-Auto-Root-zerolte-zeroltexx-smg925f.zip
- twrp-3.3.1-0-zerolte.img.tar and twrp-3.3.1-0-zerolte.img (i wonder the difference although the internet says i use .tar with Odin)
- SR5-SuperSU-v2.82-SR5-20171001224502.zip
Now, the stock ROM stops on the RECOVERY MODE with efs/ failed to mount, and when i try the custom ROM, it stops on SAMSUNG Galaxy S6 Edge. In all recovery modes, good enough my PC detects my phone's internal storage. I need to get this device to work, people.
Someone help with with a step by step tutorial, please. I am a fast learner
PS Am not a tech student or anything, am just a person who reads stuff on the internet although i understand some basic stuff on tech

1. If you think about Smart Switch Mobile, it is not for update.
2. Go back to Stock firmware via odin.
2. Have you seen >this< tutorial?
how can i know the stock firmware of the phone....i only remember the one that was updated via Smart Switch (Hanset: Samsung Galaxy S6 Edge G925F single SIM card slot no SD card slot)
1. Check your CSC on the phone box or with the Phone INFO app ★SAM★ 3.8.5.
2. Select your CSC region in the "Version" box read the instructions and download the firmware.
3. Use Odin 3.13.1 to update this model.
@ze7zez. Just bought it from some phone shop that sells used phones. I have the needed STOCK firmware already. The CSC is 02U G925F---VG4. All am getting is this image below:
Since your system is not working, go to "View recovery logs" and look for CSC or "region name".
You can also try uploading firmware from your country's region.
The CSC is 02U (O2) which according to internet research it is UK

I already have all firmwares for this handset from 02U. I have tried EVERY STOCK ROM...but all am getting is E: Failed to mount '/efs' (Invalid argument).
I tried EFS-Fix-regalstreak.tar.md5 basing on https://ajketech.wordpress.com/2016/07/27/efs-missing-factory-mode-activated-here-is-the-solution/ i got FAIL.
I do have an efs.img i made before all of this whole saga but i don't know if it is broken or okay.
Try flashing TWRP from >this< manual. Read it carefully!
With TWRP you will have more options for repair.
