i losing my efs folder and files and i dont have a backup
can i recover if i install a stock firmware on galaxy s3
if yes ,were can i download the firmware my galaxy s3 its from Portugal
help me please
Depends how you 'lost' the efs. If you deleted it then no, nothing will fix it apart from a paid repair.
If you just tried to downgrade to a firmware incompatible with your efs then flashing a 4.3 stock firmware might fix it. Download from sammobile.
no i never deleted i just install a galaxy s5 rom
but now i have installed a stock rom every thing its fine my imei its good but i can unlock my galaxy s3 SIm
how do i do my firmware its 4.3
Buy an unlock code.

Rooting your phone doesn't change your firmware.. You're still on the stock firmware unless you flashed a new rom. Goto settings>about device> and see your build.. Then goto Sammobile and downlaod the rom that is listed for Panama and matches your carrier or build whichever. Download it and flash it rom via Odin and you'll be unrooted.
though i don't see any point in unrooting. Rooted is always better.
Hi
My friend has UK 3 galaxy s2 i9100. It is sitting on stock ICS 4.03 firmware and It was previously locked but I unlocked it for him by rooting with CF-Root and installed an app Galaxy_S Unlock by helroz
It worked like a treat but now his phone is getting laggy and freezing so a re-flash of the firmware is on the cards.
I would prefer to flash the latest JB firmware for him but if need be will just re-flash current firmware and wipe to get his phone all good again
If I re-flash current firmware will I lose lock and have to re-do? or Can I even think about flashing latest JB and still be able to maintain unlock or be able to re-unlock it?
The unlock app says it modified nv_data.bin so is that just an option to backup the nv_data and restore it after reflash?
Appreciate any advice.. cheers
His current build is XWLP7 baseband I9100NELP3
Hello Guys. I went into a bit trouble here...
I have Samsung S3 for more than 1 year, and I already flashing it with custom ROM without proper backup (foolish yeah i know)...
And now, I want to return to my official stock rom (unroot). Since i am from Indonesia, I found that the latest firmware my country has from S3 is 4.1.2 (from samsung-updates and sammobile websites) like this :
GT-I9300 Galaxy S III
PDA: I9300XXEMF6
CSC: I9300OLBEMF3
MODEM: I9300DXEMB1
Added: 2013-07-23
I reset the binary counter with triangle away and unroot it with mobile odin, but the problem is my imei was like "0049...../1" and I cannot make any calls or sms (not registered from network).
After reading a bunch of threads, i found the solution was to root it back again and install modem XXEMG4...
Is there anything I could do to have a working unroot phone? like using official stock rom from other country perhaps?
cheers
Yes it is the Modem problem. And for heaven's sake as soon as you root make a backup and backup your efs partition as well before you get into a bigger mess. Flash a stock rom that has the modem MG4 or flash a 4.3 rom of any country it hardly matters.
If i unroot it with a 4.3 rom from any country, then can i update through option "software update" or should i flash it again if there is any update in the future?
Thanks for the explanation!

no i dont think...but you can try by KIES..that may be possible..but some users have reported that kies also doesnt work for them..but you always have ODIN to flash firmware of other country or any your country whenevr it comes..
:good:
So i still have to root it?
Root doesn't matter, you cannot use the firmware of modem for your country as it is efs v1 and you didn't take a backup before you changed to v2.
There is no way back, you'll just have to wait for 4.3 to be released in your country if you want stock and unmodified status again.

No, you can't downgrade unless you have an efs backup from before EMG4 firmware.

flash this from cwm it fixes
hit thanks if i helped you
@ferristah: this will install various modems and fix nothing.
Tell me how
how did you downgraded ?
which firmware you used ?
Just flash 4.1.2 with Odin and backup your EFS
Hi,
I'm sorry if this has been asked before but I ran a custom rom for a while on my Galaxy S3 GT-I9300 and now I want to restore it back to stock. According to my phone's menu, the baseband version is I9300XXUGNB1 but that version is not te be found on Sammobile firmwares. Can I safely install another rom with another baseband version? For example I9300XXUGNJ? (Netherlands). Or will I risk bricking my phone? To my knowledge the S3 I own isn't uncommon or anything. It's just a carrier- and simlock free phone which I bought at a major electronics retailer at the time.
Thanks in advance.
Hello and thank you for using Q/A,
you can flash all ROMs. But please keep in mind to backup EFS and then flash.
Kind regards
Trafalgar Square
so lets just say.. god forbid, the efs partition got facked at some point.. i may as well consider the phone bricked?
no you should be able to flash stock with odin and start all over (no root) if you didn't backup efs
not sure how its done though
