Official JB update

Hello,
I have Samsung Galaxy Ace 2, but still no official update yet. When i click on update it says no updates available. Why is that? I live in Lithuania.
Thanks.
There's no official JB update in Lithuania for the i8160 yet, maybe or the L version.
You can however odin-flash German (DBT) XXMF1, but you will have an European CSC.

But it is going to be right? Do i need to root before odin-flash? Current CSC is LL2 (SEB)
Flashing with Odin is harmless if done properly.
If your CSC is SEB then you have OXE multi-CSC... By installing MF1 you would get OXX multi-CSC which I don't think contains SEB CSC (neither Thailand).
You don't need root permissions to flash with Odin, you just have to boot the phone while pressing VolDown+Home+Power and enter Download Mode, load the files in Odin, connect the phone via USB (and let it install drivers from Kies, which should be already installed but not running) and press Start!
And always remember to Wipe data/factory reset from the recovery menu (VolUp+Home+Power).

[Q] flashing via ODIN 3.09 related question

So I have a small problem and few questions.
I've bought S4mini in Poland where i live, but with SEB (Baltic) region firmware.
when I type in phone *#1234# I get:
AP: i9195XXUAMG8
CP: i9195XXUAMG8
CSC: I91950XXAMG4
Question no. 1 - what does it mean, and shouldn't be there 3x MG8 ?
Question no. 2 - when I flash with Odin 3.09 firmware for polish region (XEO) from Samsung-Updates.com, Kies will identify my phone firmware as polish XEO , and I will be able to recieve OTA from my region and flash it normally?
Question no. 3 - on Samsung-Updates.com is big firmware file and separatly kernel file. I should flash both or the kernell is also includet in md5 firmware file? If not, haw to flash only kernel in Odin? - the same procedure as firmware?
I'm doing this, because I'm experiencing big battery drain in standby mode, and it seems like its radio related. When this won't help I'll flash CM 10.1 as my last solution.
thanks in advance
ps. this is my wifes phone, so if I broke it she will kill me

Roll back to any NEE 4.1.1 firmware. Change the csc with csc changer, triangle away if needed, flash 4.1.2, factory reset and you're back on warranty with your original csc.
It all worked out anyway.
Flashed 4.1.2
Flashed auto root
Triangle away
Changed csc to NEE
Full unroot in superSu
Factory reset
OTA and Kies success :good:
is it safe to flash csc file with newer versions of roms to have language that we need?

Can't go back to default firmware

I flashed BTU (UK) firmware to my XSA (AUS) NOTE10+ and now trying to flash to new XSA that was released yesterday but having issues.
After XSA flash, it boots into recovery mode saying your data might be corrupted, I tried to choose try again option but it gives error screen and boot back to recovery mode.
AP, BL, CP and CSC are all choosen in odin, no other setting was touched.
So I flashed back to BTU and my phone restore back fine. I'm using HOME_CSC as I don't want to reset my phone.
Same result for older firmware for both BTU and XSA, I just can't go back.
Anyone having simillar issue? Can this be fixed or only way is full reset?
XSA firmware is N975FXXU1BSLA/N975FOXM1BSLA/N975FXXU1BSL4
BTU is N975FXXS1BSLD/N975FOXM1BSL7/N975FXXU1BSL4

Will Flashing updated firmware wipe out data?

My A505F has official INS firmware, if I flash any other firmware like PAK firmware by selecting home csc option in odin, will my data be wiped out??
