What do you really mean? from where are you accessing and what?
Why you want extract...? for removing any specific app?
If you have a CWM back up of earlier ROM, you can use Titanium Backup Pro for individual apps installation for installing from your earlier ROM....
I just wanted to do it in case I would like to back up to original state before rooting and flashing CM7.

Sorry to say you cant backup your current ROM till you root your phone...
Use checkfus to download original firmware .

If you use CWM you do not back up original as it has cwm and root kernel ,

Ok, I have back up my phone just after root so I have possibilty to back my stock T-mobile brand firmware but with root.
I want to roll back to the stock rom, I dont have the firmware but my parents phones are still stock so can I get the stock firmware from their phones?
if so, how?

you can simply download a stock rom from e.g. sammobile.com and flash it via Odin.
if you really want it from your parent's phone: you have to root (I think you cannot make a nandroid with stock recovery?), make a nandroid backup, un-root their phone (follow the guides in general's stickies)

If you got the I9300 model with no sim lock- no problem.
Ps- notice that if your current build is below EMG4, than your file partition will be changed to EFSv2,
needs to be noticed if you'll try to go back to 4.1.2 afterwards

I think he can go back after flashing 4.3 ROM. I have done that.
Aashish, you can install any ROM as per your requirement if SIM is not locked with any SP.
But there is a chances of loosing IMEI. So please take backup. Search and download MG4 modem handy.

Yeah what you propose seems very straightforward BUT it would be advisable to do a full backup INCLUDING EFS, just check the EFS box in TWRP for instance, as it's not usually included in a backup by default.

Ah I get it now, in which case I would be tempted to go to an Indian 4.1.2 firmware through ODIN and the update through OTA if that's possible. That would reduce the chase of stuffing up your EFS by using an official Samsung update procedure.
Hey Guys.
Once i tried to downgrade my Galaxy S6 Edge SM-G925F from Marshmallow to Lollipop with odin, but it failed and i had a brick. I tried different Versions of Odin and with much luck i fixed my Phone. But now i am insecure and hope to get help from you. I installed latest Smart Switch Version. What do i have to do to downgrade without bricking my Device?

Only possible when flashing 5.1.1 custom rom via recovery, but you will lose your imei, BUT you can backup your imei and after flashing new rom restore it.

Yes before you proceed you will need to install a "custom recovery" (Search about it if you dont know what it is)
Go to recovery like you want to format but instead go to "Backup & Restore" and select backup and then select "efs" which is IMEI.
After flashing a custom rom and after the first boot you will notice that there is no signal, so go to recovery and select to restore efs.
I recommend you to backup efs to ext sd card.
This will void your warranty, even downgrading it self will void it.
Goodluck!

Any firmware 4DPG1 or above can not be downgraded. Im guessing before you was on U3DPAD or lower which can be downgraded. The first MM builds could be downgraded. But any 4xxxx can not
ah ok....
then i downgraded fast enough
my main reason of downgrade:
in MM it is not possible to change the font with HiFont App....!!!
i see other people saying that it's possible.
but i have one of the latest builds so, in your opinion , it is impossible for me to downgrade.
but are you sure? i can't believe that, i want absolutely a solution, i am searching it from so many time, please help

What build number are you in? It is impossible to downgrade from a late build 4xxxx. I have tried absolutely everything. The only way is to flash a nandroid backup but even then you will lose imei. You can always back up efs and restore but its not always as straight forward to restore it. You would also need to flash a new bootloader and modem.
Did you make a nandroid backup of your previous firmware? If not then you cant try that.
The only other way you can try is to flash a 5.1.1 custom rom. Again you will lose imei. So efs backup is important. You would also need to flash BL and modem again.
There are roms based on lollipop which is a much safer way to revert back, try one of them.
Overall i wouldnt try it bit its up to you. If you do and you find a way to do it let me know.

You cant downgrade after 4xxxx firmware mate. After updated bootloader your stuck on mm.
There are ROMs based on 5.1.1. But because you flashed 4xxxx firmware you cant downgrade. All lollipop firmwares are 3xxxx
