Once you upgrade your firmware you can't downgrade. When you install mg9 you can't go back. Backup your folder now if you have the correct imei, and if you lose your imei try to restore using this guide

FYI: I just finished flashing the MF3 TTT version... PDA, PHONE, CSC, MODEM and PIT... not working either.

I made the IMEI backup when I just deployed latest version MG9... So it's not an IMEI backup from old versions.

tamirda, any idea what can be down to downgrade ?

tks!

Mf3 is old version. I told you that you cannot downgrade so why you installed mf3?

[Galaxy S 4 i9500 Android Development] nabil alami:
As i understand here is what you to do:

1. flash MG9 (plus modem i think)

2. Restore IMEI Backup

3. Everything should work
[Galaxy S 4 i9500 Android Development] umoraes:
tamirda - the problem is: MG9 (latest firmware) is no good in my area. On MG9 I don't have IMEI problem... it shows the correct IMEI. That's the reason I'm looking a way to downgrade. Just a matter of MG9 has no good 3G reception. is there something I can do ? And, Why isn't possible to downgrade ? where does samsung store the information that I can't downgrade once I installed everything from scratch ? thanks.
[Galaxy S 4 i9500 Android Development] tamirda:
You Can Not Downgrade!

Use MG9 Till newer base comes out, till then We can not help you if you don't understand that you can not downgrade.
[Galaxy S 4 i9500 Android Development] nabil alami:
Isnt MG1 and MG5 newer or are they older....just asking
[Galaxy S 4 i9500 Android Development] tamirda:
XWUBMG5 is the newest but this ersion causes for IMEI brick.

XXUBMG9/UBUBMG9 are the safe newer versions.
[Galaxy S 4 i9500 Android Development] umoraes:
you should respect people - specially those looking for help. If you don't agree or don't have patience - don't answer. It's so sad to have a senior member in the board with such behaivor. I wish you have a great time in weekend so you get your patience back.
[Galaxy S 4 i9500 Android Development] tamirda:
Its not that I don't respect you, it is just I said it at least 6 times this 2 hours that I try to help you.

You keep trying to install older versions when I am telling you that you can't. The reason is that when you install the newer version it changes something in the EFS folder location that older versions can not find it and give you broken IMEI, and there is no fix for that, only to use mg9 till newer version comes out.

I gave you the solution but you keep trying older versions. There is nothing more that me or other people here can help you.

When you say "don't agree" - pay attention that it is not just don't agree, it is because I know no one can help you with that, including me, because I wrote this thread after alot of tests, so you can keep arguing with me or use what I told you.
[Galaxy S 4 i9500 Android Development] starscream0:
dude you should really listen to what tamirda has to say!! go back a few posts and read what happen to my device because of a downgrade!

Luckily i was able to pull out from it after like 4-5 days of desperately searching forums across the internet.

Do not mess with your efs folder! if you dont have a backup you're screwed!

just wait till newer base come up my friend.

A simple question - if I face a problem with imei, will flashing a stock fw via odin will revert things and solve it?

Thanks
[Galaxy S 4 i9500 Android Development] tamirda:
I don't think so, it might be a solution if you have old firmware but EFS is not invluded in a stock rom and that is why you need to backup efs first.
[Galaxy S 4 i9500 Android Development] marc_ecko28:
Wrong info mate. I came from UBUBMG9 and it also bricked my IMEI, good thing I fixed it and restore my IMEI
[Galaxy S 4 i9500 Android Development] tamirda:
Wrong info that helped for many of my users.
[Galaxy S 4 i9500 Android Development] marc_ecko28:
Yes I know. Im not saying against the thread.

But...

What I mean is that you are saying mg9 cant brick imei. Im just saying that i came from ububmg9 firmware and it bricked my imei.
[Galaxy S 4 i9500 Android Development] nabil alami:
He didnt say that it cant brick he said that they are the most stable versions while the others will DEFINITELY brick it.

[Galaxy S 4 i9500 Android Development] marc_ecko28:
Btw brick and lost imei is very different... lol
[Galaxy S 4 i9500 Android Development] nabil alami:
Thats what I used to think until I saw the amount of posts :p I actually once lost the IMEI number on my Galaxy S1 but recovered it very easily....:D

But thanks for giving me hope lool
[Galaxy S 4 i9500 Android Development] ophirb:
In that case who puts the efs dir on the phone in the first place? It hard to believe it is done in a separate process from the fw.
[Galaxy S 4 i9500 Android Development] tamirda:
Blame samsung.

Samsung as far as I know is the only company who puts IMEI & serial in a folder that can be deleted.

MH1 is newer, so you can not downgrade, you can flash only MH1 or higher.

Can I backup EFS folder with root explorer and paste it back when this problem would happen?
[Galaxy S 4 i9500 Android Development] PutraMasyers97:
Hi.. I try to do 4 way of Backup My EFS..

1. Using ES File Explorer with root access. And then I copy efs folder from system to my External SD Card...

2. Using Terminal Emulator (.img). I type dd if=/dev/block/mmcblk0p3 of=/sdcard/efs.img bs 4096

3. Using Terminal Emulator (.img). I type dd if=/dev/block/mmcblk0p10 of=/sdcard/efs.img (Follow up on YouTube)

4. .tar.gz = NOT WORKING!!

From these 3 working backup, All of these 3 backup size are not same..

1. ES File Explorer (copy/paste) = 6.01 MB

2. .img (mmcblk0p3) = 20.00 MB

3. .img (mmcblk0p10) = 8.00 MB

So i was so confuse with one is the the true backup..

Please note that I was using SAMSUNG GALAXY S4 GT-I9500 with LATEST MALAYSIA FIRMWARE. And I was on STOCK ROM On STOCK KERNEL with root and CWM 6.0.3.2 from clockworkmod website.

Amm I guess you can try it, but be careful and flash PIT like the installation instructions here:

The stock you are flashing should be the one with knox MJ5/8.

Adonis pit you can get here:

Use odin v3.09

If it still doesn't work, you will have to talk with smasung that you don't have call signal(don't say IMEI or something.. act like someone who doesn't know what is ROOT and recovery hehe)

It is very simple, more than using these manually methods.

I just tried HC-kTool app on i9000 and it says not compatible, and also "Efs" app doesnt work.

I've been using a Venom ROM for quite some time. But after a while it started generating some bugs. Because I have a Tegra 3 device I'm not able to install the new versions anymore...

Looking at the past periods the most important part of the ROM are the OTA upgrades. So I'm now thinking about going back to the stock ROM, but I'm not able to find a good way to keep all my data/settings while doing so. I do have Titanium backup, but is it possible to restore the file on an unrooted device with a different ROM? Or is it possible to flash the stock ROM, keep all functionality and still be rooted?
