I9300 Samsung S3 without serial how to upgrade? - Galaxy S III Q&A, Help & Troubleshooting

Hello everyone,
I´m on Cyanogen 4.2.2, I lost once my IMEI and serial, I could get back my IMEI but not my serial number. Now I need a patched Kernel / Modem for this problem.
What would be the best version to update to and how / where could I find the needed files?

[Q] Anyway to know what your stock rom was?

Hi,
I am a noob to XDA and this is my first post, please dont be mean!! I recently bought a galaxy s2 unlocked version from amazon.com and when i received it i flashed in the new leaked jellybean rom:
Android version: 4.1.2
Baseband version: I9100XXLS6
Kernel version: 3.0.21-462349
[email protected] #3
SMP PREEMPT
Build number: JZO54K.I9100XXLSJ
After flashing this new rom my IMEI number had been reset and i am currently getting no network service. The samsung SRS tool is not picking up my phone for some unknown reason to let me reset the IMEI number. Before flashing the new rom i did not take stock of what the original rom was!! Is there anyway to know what the stock rom was before flashing?
Please help!!!!
Well if it was the factory unlocked version, my guess is you had stock unbranded gingerbread.
unbranded

When you say, your IMEI number has been reset, I think, the efs folder got corrupted. its where the phone data like IMEI number is stored.
And if you want to flash stock kernel, you can visit this site, but I'm not sure how you can retrieve this efs folder data.

Your IMEI is also printed on the sticker beneath your phones' battery.
Your probably seeing the sim lock bug and getting confused. if you flash the leaked JB rom your sim lock will be enabled so you will need to use a unlock app.
Use search, we have plenty of topics that cover this since JB leak.
and then some.....

yea i know it is but the imei number behind the battery and the one i am seeing when i dial *#06# are different. i am seeing alot of 9999's and 000's in it..when i googled it i saw it was some sort of manufacturer's default imei or something. i flashed in an unbranded uk rom xwlp7 but when i try to root it using cf-root it is not working now!!!

samsung s3 help
could you please link me to a solved thread with this exact problem please
unless you backed up your efs partition . you cant revert to an older modem . my advice for now is stay with mg4 and back up efs . apparently for as of right now if you change your modem you will most likely lose your imei

[Q] How to revert back from 4.3 to 4.1.2 (Malaysia Region)

Hi guys. I need some helps. I'm from Malaysia and the android that i used before is android 4.1.2 I9300XXEMF6 (original firmware). Then ive upgraded it into android 4.3 (I9300XXUGMJ9) for UK region. Even though it is an official samsung firmware, i found out it is unstable. I flash it back to android 4.1.2 (Malaysia original firmware) but something happen. The "network have not registered" problem. I then found the solution by rooting it and install the modem. But it act funnily as the android seems unstable from before. I flash it over and over again hoping that reverting back to 4.1.2 will be the same as before but i ended up using 4.2 as the 4.1.2 have network problem. I already search the forum and find many solutions but none provide the files that i need. I also have tried KIES method by recovery and initializing method but it resulted the same. "Network has not registered. The only solution is to root it and i would really like to NOT to root my phone.
My question is, can someone provide me with necessary files such as the pit files, phone (modem) and the CSC files that specifically for Malaysia regions? I already have the firmware file. Please guys. The instability of 4.3 is driving me crazy.
BTW im using i9300.
Stop.
You are going to brick your phone if you flash things without understanding them.
Go to general forum and read the sticky post, especially efs 'know this stuff'.
Flashing a pit file WILL brick your phone.
When you flashed 4.3 you upgraded to efs v2, there is no way back. You can only use EMGx and later modems now, find a later modem that will work in your country, either with 4.1 or 4.3.
Edit. Backup your efs, perform a factory reset, flash your 4.1 country rom then an EMG modem.
hey man, thanks. One question, where can i find this emg modem?

What you`ll need is a new version of 4.1.2 with a mg4 baseband or latest, the 4.3 rom changed your efs folder format. If you want to stick with your 4.1.2 go to http://forum.xda-developers.com/showpost.php?p=43946365&postcount=15 and flash that emergency.zip (mg4 baseband), it should do the job.
Hi guys. Already solved the network problem by installing the Modem DDEMG2 files via odin. Thanks for your guys helps and advice. For some that thinks that i haven't read many posts, i have read them but cannot grasp the concept. Sorry for the inconvenience. Many thanks.

[Q] i9300 freezing with Cyanogenmod 10.2

I have an international version of the Galaxy S3, the i9300 and I'm facing freezes with Cyanogenmod 10.2. I heard that these problems could be caused by baseband version, I tried to use GetRIL to update the RIL and it updated successfully but only the RIL, how can I check which version of the baseband I must to update and how do I update the baseband ? It is done via Odin ? Where are the download files ? I couldn't find any version for my region (Brazil). My actual baseband version is I9300UBELL1. Thanks !

i don't think so... just try to flash another rom like Temasek or Paranoid android... second me you can solve your problem..
you tried to return to a stock? I do not think the problem is baseband, but maybe the CM was installed wrong. even so, you can find zip files or baseband modem, to install recovery via advanced.
Try using the CyanogenMod installer.

Look here to solve >> http://forum.xda-developers.com/galaxy-s3/general/ref-imei-efs-stuff-i9300-including-t2393289 <<
you have to flash older baseband if the problem occured after upgrading. ie. you were on 4.0 (older) and flashed 4.3 (newer) you have to flash the older baseband. (the modem file of 4.0).
if you dont get this. try
1. flashing the original stock rom
2. flash other modem files.
dont forget to hit thaks if i helped you n any way
