Hi!
I have a problem with my Samsung Galaxy Y from T-Mobile Poland. I upgraded soft witch KIES to 2.3.6 and everything was ok. But after a two weeks there was a problem witch internet via 3g. It wasn't too bad for me. But from yesterday wifi is not working. So i reset to factory settings via recovery menu. it didn't help me. So i tried reset from phone's settings. And after that the IMEI number is gone. And when i connect phone to pc KIES says "Your device doesn't support firmware upgrade via apl." And generally i can't install aplications for root which means i can't restore backup via MyBackup or Titan Backup. My phone was rooted.
What can i do? Sorry for my english i'm from Poland.
Could someone help me?
Hi there!
I know I'm new to here, but not new to android, flashing, etc...
So I recently bought a Galaxy S3 international version (GT-I9300).
I tried to update it's software with KIES, and it stopped on 61%.
KIES tried to flash the newest 4.0.4 (UK) firmware (I9300XXBLG8).
I got the .tar.md5 file out of temporary directory and flashed it manually from ODIN. It booted normally, but i had (have) no network signal. When I turned it on it requested my PIN but when I entered it, the phone doesn't connected to my carrieer's network. My phone is unlocked (checked it with galaxsim), and my IMEI number doesn't changed or corrupted. (Checked under the battery). I live in Hungary and my carrieer is T-Mobile. Tried hard reset, wipe.
Can anybody please help me to solve this problem?
Thank you very much in advance.

Hi Tom ,
it happened that I had a bit of a similar problem before ( not with my Current International S3 but with my older Xperia neo v ) , after flashing a new ROM something went wrong and I had lost network , tried everything possible but it wouldn't do anything.
my solution was flashing back to my previous ROM , so I highly recommend to you to flash back using your NANDROID backup ( I hope you made one before Flashing... ) or you can try another ROM / or even RE-flash your current ROM but pay more attention this time and make sure nothing goes wrong , and also make sure you do a factory reset , Cache wipe and Dalvik cache Wipe before you flash it just to make sure everything is clean.
I hope this helps , and if I helped you by any way possible don't hesitate and press the Thanks button on your LEFT :good:
Cheers

OT I don't have thanks buttons, maybe you should qualify with an IF statement?
Bad news, I don't really know what my original firmware was, so I can just try Kangburra's tip... I have 25 min waiting time on hotfile.com, I will the download the latest 4.1.1 unbranded firmware, which has PDA I9300XXDLIH and CSC I9300PHEDLI1. I will write about the results ASAP.
edit: I'm too tired, I thoght your signature was a suggestion for me

It seems you misunderstood me... I have absolutely no network signal from my carrier :/
Update: Okay the last 4.1.1 mentioned before is not working. Now it sees my network just doesn't register on it. Will try I9300XXALE8_I9300OXFALE5_XEH now.
Found something: All of ROMs installed I'm seem to be reachable. My friend ringed me from his mobile and IT WAS RINGING. If I turned off my mobile, it was not ringing of course. So what the hell is this?
Hey Guys,
First time poster.. so please don't flame me...eh!..LOL
I have searched and better searched without success to my question..
I would like to revert back to JB 4.1.2 on my S3 which is SIM locked to T-Mobile UK, would I need to ROOT the phone beforehand or can I just use Odin and the relevant stock firmware.
would this affect the IMEI and the EFS folder that would make the phone unusable?.
if the procedure is straightforward would I be able to revert back to perhaps 4.1.1 (which would allow me to unlock the SIM myself..).
Hope I have made some sense with my first post..
cheers for any help guys...
4.3 changed your efs to v2. You cannot go back to 4.1.1 unless you have an efs backup from before you upgraded (an efs v1 backup).
Going back to 4.1.2 will work provided you use a firmware EMGx or later (efs v2).
Follow the guides in general stickies on how to flash stock using odin, root afterward with CF auto root.
There are many threads on efs changes, efs 'know this stuff' in particular.

Do you mean this firmware I9300XXEMG4
cheers
cancel all that... I have managed to flash my s3 with the I9300XXEMG4 firmware..... and truth be told I was crapping myself when the phone kept looping on the logo screen.... I did a factory reset and cleared the cache.....all is working.....
just a quick update...
My phone is working fine and dandy with the 4.1.2 stock firmware.... I have also discovered that the SIM is unlocked (or was not locked to begin with), tried a Tesco mobile SIM in it last night and it worked fine, was not asked to input unlocking code for it!
result all round..... :laugh:
You help me too. Thx.
So guys, please explain this to me.
After I did an update to 4.3 the efs was changed. I was ok with that, until my hard drive died and I had lost 4.1.2 backup and so, I can't restore my efs.
The problem is: Can i downgrade to I9300XXEMG4 without problems? I mean, I will not have IMEI and network signal problems? I did flashed some 4.3 roms, but I'm not satisfied with them.
after effect in this downgrading process on my s3
I have upgraded from 4.1.2 XXEMH4 to 4.3 GMJ9 VDI first. liked that very much, display battery backup[battery doctor] was on my phone but drains quickly though in reality with lag issue. i found few things in 4.3:
1. time lag,
2. emulated drive
3. IMEI shows correctly but its SW ver shows 11 instead original 01
there were dozens of good features over above these aforementioned issues.
Sometimes wanted to use Samsung's Indian keyboard, downgraded therefore back to xxemh(4.1.2)..
Problems I found,
a. IMEI shows correctly with original SW version 01 but mobile shuts down suddenly quite frequently.
b. my csc becomes unknown while typing *#1234#
c. Both USB and UART options change to modem every phone boots
d. rooted and found csc folder is missing
e. wifi gpars work but Bluetooth can not be turned ON it becomes gray . sometimes phone hangs when I try to put it ON. it restarts automatically at times.
f. phone lags just like that of 4.3
is there any method settle problems of a., c., e. and f.??

Suggest wipe phone via recovery
Mounts and storage format sd card system cache data .
Boot to download mode and flash stock rom for your network .

@JJEgan, thanks for the reply and tips!
a. IMEI shows correctly with original SW version 01 but mobile shuts down suddenly quite frequently.
>>>Mobile as in what network or the phone ??
---Mobile is in Vodafone India on my I9300
b. my csc becomes unknown while typing *#1234# [SOLVED]
>. Flash the correct CSC for your network.
--CSC folder has been recovered this way in the process: re-flashed 4.3 (swc) on existing 4.1.2 (xxemh4), sw version of imei changes to version 11 however IMEI remains same, them flashed another itv (4.1.2) as explained in another thread. I lost imei as it becomes 049....
then I flashed back to my country's 4.1.2 (xxemh4). got IMEIand its sw version correctly and my CSC folder also.
EVERYTIME I FLASH I DO FACTORY RESET AND CACHE WIPE compulsorily FROM stock recovery 3(e)
--------------------------
I HAVE BEEN READING A LOT SINCE LAST FIVE DAYS, basics of flashing I guess I know as i have been doing this since 2009[Samsung Bada on GT-S6353]. I use only stock recovery and stock roms. my problems now reduce to:
1. Bluetooth non functional- can not make it ON. When I slide Bluetooth button to make it ON, phone either hangs and restarts automatically or Bluetooth button goes back original OFF position
2. phone's utilities reset to modem automatically [both UART & USB]. I check this when my s3 can not connect to pc or kies to reload my contacts on s3. This is checked by typing *#7284# and I need to set it UART => MODEM & USB => PDA. But these two setting reset to MODEM automatically whenever I check at later stage [when i found pc doesn't recognise s3].
3. phone lags just like 4.3 even in 4.1.2 [xxemh4]
I will do flashing again! Thanks once again!
=================
Flashing done! It doesn't help me
Khaaba,

I am also facing same issues.
Thanks and regards

Use this link and flash with "I9300XXEMG4_KOR_MULTI_FACTORY". That's the method I followed!
Everything is normal. Then I flashed my country's FW using Odin in PDA mode only!
Hello.
I have a problem which annoys me a lot for a half a year now. Here's the story:
I bought my S3 from secondhand in 2012. It was Android 4.1.2. I was complete newbie that day. When update came off, I wanted to update it via my phone, bu then i threw errors. then i tried it via Kies but also did not managed to. I googled the problem and saw that I am rooted. I listened to people, who said that I should use Odin to upgrade my firmware, So did I. Downloaded latest firmware from sammobile.com. i did everything following the tutorial, but I got the network problem - no connection to the service - no sms, calls, 3g and so on. Only wifi. Then I spend three days trying to google out the problem. Tried almost everything, but as I didint had any backups made for my EFS, and my IMEI was "unknown" as phone said, I assumed that there is nothing i can do there. So I gave phone to the repair service. They fixed it in a day. I got it with the old 4.1.2 firmware version and enjoyed my phone like a year for now. And immediately backed up EFS.
So today I thought that im very bored with this old 4.1.2 and encouraged myself to try upgrade it again. So as I have efs backup, (I also did modem backup) I tried downloading latest 4.3 fimware from sammobile again. (as Im from Lithuania, there is no firmwared for LT, so I downloaded Croatian, because the carrier was the same (Tele2). And here I go again. No network, only wifi. I tried to restore efs, modem - no change with network (Did not managed to recover modem corectly, Odin fails when i want to recover it). then I tried several modems from Perkas file Stash, which i managed install via Odin, but still no change. I truly tried almost every app ant searched every thread in this forum for solution.
Now I tried to flash in to 4.1.2 I9300XXEMG4 firmware. And now im stuck with Samsung logo, mobile does not even turn on.
Any solutions? I will apprecaite any information. Thanks
There is no single solution, once the efs is damaged only a reputable repair centre can recode it properly. If it comes back with 4.1 then it isn't hasn't been fixed properly.

Hello everyone.
My problem is simple, I can't change the modem.
More information:
I got my P780 some time ago with 4.2 from the vendor. For some days now, the device was softbrick'd. After a complete flash and 3 days of back and forth I got 4.4.2 S221 Life installed with TWRP and CWM recovery (can easily change between). With this version i actually CAN (miracly!) connect not only to 3G, but to 2G!! (Only version so far for me)
If it helps, I live in Germany and probably got the chinese version (chinese letters written on battery)
Problem is, the connection is not very stable :/
So I decided to switch the modem to v51. That's where the problems start. I got the zip on the ext_SD, flashed with TWRP and CWM and wiped the cache. But the "Baseband version" is still at "P780.V101..........", even after several modems, it does nothing!
My second problem is, that the WLAN-connection only works once. I enter the password, it works and after I got out of range and back in it won't connect again!! I have to "Forget" the connection and connect all over again with entering the password.
I really hope you can help me

Thanks for the quick reply.
Unfortunatly this doesn't help either. I flashed it, but the signal strength is nevertheless bouncing between nothing (maybe 10db above noise) and full reception. Also in 2G as well as in 3G.
AND the Baseband version haven't changed at all (still v101)
what i noticed is with Alice Project i got the best signal reception for WIFI and for phone also ... its using baseband of S920.V101 may be thats why...
or alternatively serach for S920 modem drivers and give a try ..
cheers

I tried nearly every modem I could find (around 15-20) but none changed the baseband version or anything.
Thats my problem
