[Q] Quesiton about MG4 baseband - Galaxy S III Q&A, Help & Troubleshooting

I recently flashed MG4 base-band and didn't backup my EFS direction.
I know that MG4 and MG2 changes the EFS partition and it messes up your IMEI code.
So how do I get rid of that "locking" that stops me from flashing other basebands?
I'm currently on MD3 PHONE and MG4 baseband.
Would the backup of current EFS with HC-kTool help when I flash other baseband and restore the efs.img?

Its actually the rom not the baseband that changes efs
No backup, no going back

So basically If I backup now when I'm in MG4 baseband the backup won't work if I switch to another ROM with different baseband?

The backup will work as a backup of "now". The backup cannot revert you to a "before now" state. Backups only take you back to the moment when the backup was taken. Not before

I mean if I flash another baseband and restore the backup that I did now, will my IMEI reset ?

I don't understand the question. Why would you restore the backup?
You can't use any baseband older than mg2. End of story

That's what I'm asking. Meaning I'm forever stuck with MG basebands?

Or newer (when released)

So there's no way of getting rid of MG baseband with working IMEI?

You're trying to joke with me now?

Did you have EMG4 at any point?
edit > Pardus is EMG4,
Have you still got the MG4 baseband?

Baseband = modem = radio.
it MUST be MG4 on an MG4 ROM. Pardus comes with MG4 baseband. Did you flash another?
Ariza is not a baseband :/

If it was mg4, you need to send for repair

I don't know was it mg4 I buyed the phone couple days ago, and then i flashed leaked 4.2.2 firmware, then i installed pardus rom then i noticed no network, and when i look at my IMEI 0049 first 4 numbers
The thing is mg4 baseband changes format of efs folder. Pardus is mg4. So now there are 2 choices...
1) restore efs (not option you said)
2) ensure you have mg4 baseband.
Once you have flashed mg4, mg4 is the only baseband that can read efs (and in turn - imei).
So make sure you have mg4 baseband
If you do have mg4 baseband already and imei still gone, you need to send for repair

Don't flash anything until you take time to read the faqs and guides .
basic knowledge is required ignorance just leads to a bricked phone .

And back up your efs now, today, to three different places, then back it up to two more to be sure.

No network connection after custom ROM install

Hi,
I was trying some different ROM's on my i9300 (UK 3 network) and had various problems with all of them but eventually decided to stick with Omega v46.1 Jelly Bean 4.2.2. All seemed to be good last night in the house but today I can't connect to the network (wifi works fine). I tried restoring a backup and re-flashing to stock (using Odin) but I still can't connect to the network.
Thoughts?

Apn correct? Does the imei match the sticker?
What was the last rom you had that could connect

Ok. I believe pardus uses XXEMG4 as a base? Could you check that please?
If so read the imei / efs thread linked in my signature

And yes Pradus does use XXEMG4
Given I don't have a backup of my /efs what are my options?
As per the thread, you have 2 options.
1) go back to pardus
2) locate an mg4 baseband and flash it

when you flashed a custom rom you probably used a rom that included a newer baseband. Such as emg2 or emg4. maybe you did not have the correct apn settings and you were not connecting to your network . then when you flashed stock , perhaps you flashed and older baseband. that older baseband can no longer read your efs partition which contains imei and serial. a possible solution if you did not back up your efs folder is to flash an emg2 or emg4 baseband . or a full stock rom which uses an emg2 or emg4 baseband. all of this is explained in the stickies. the best way to learn is to read them. good luck
Ok.thanks. i wil inform

did you try to flash an emg2 or emg4 baseband? some have reported that this can restore network connection

EFS 2.0

The 4.3 firmware have efs 2.0 i guess...
I am on 4.1.2 and that has efs 1.0. Is there anything that I need to worry about when updating the firmware over kies?
If you haven't read about the changes it brings then yes, you may needed to worry.

Just don't forget to backup your efs before you upgrade and you'll be alright.

Galaxy S3 accelerometer and magnetic sensor not working

Hi, this two sensors just stopped working after update to 4.3. I've tried installing custom rom but still nothing. All my other sensors are working fine but theese two aren't giving me any data. Any help?
Factory reset and flash full stock rom with odin. If still the same then you have a hardware fault.

I've tried that but still not working. Do I need to downgrade to 4.1.2?
I don't think it will make any difference, but won't harm to check. Make sure you use an efs v2 4.1 firmware.

Now you lost me. What is efs v2 4.1 firmware?
Firmware EMG4 and later all require efs v2 format for the IMEI number to be read, by updating to 4.3 you now have v2 and cannot use a firmware earlier than EMG4, otherwise your efs (and IMEI) will be corrupted.
