[Q] Root and efs backup

Hi all guys! I'm new to this phone
I have i8190L (Latin) variant of the s3 mini, Android 4.1.1, the CHE csc code (Chilean Entel network provider firmware), and I want to install the latest 4.1.2 firmware for my country generic firmware (CHO csc code).
But for being sure, it's recommended to do an efs folder backup, and I have to be rooted for doing that. But the only way to get root is to flash another pre-rooted firmware, and that process can screw up my efs folder anyway.
What can I do? I don't want to f*** up my phone
Thx in advance, and sorry for my English
Sent from my GT-I8190L using xda app-developers app
EDIT: Already rooted with a method which is not necessary to flash some pre-rooted firmware.

[Q] new cf-auto-root

heloo to everyone.
has anyone tried the new CF-AUTO-ROOT for android 4.4.4 and device model M3XX that has been uploaded yesterday.
I have stock germany firmware 4.4.4 with the new bootloader and SECURE DOWNLOAD Enabled in Knox, do you think if i flash this with odin will root my device?
thank you.

officially the most simple way to root i9305
tried the new added cf-auto-root for I9305 lte.
flashed it with odin...which comes in the archive and it works like a charm on 4.4.4 stock Germany firmware.
Thank you chainfire.

[Q] when PDA & CSC dont match how to flash new rom

hey hello to all out there
Basically i am new in the forum but not to its threads which have always been a great help to me when it comes to rooting my smart devices or making them more efficient or whatevr so finally joined it to avial even more fun !
Well i own a Samsung Galaxy S3 GT- i9305 4G LTE which i rooted months back in order to install android kikkat 4.4 .But i later found that the android kikkat versions available den, were not the officail ones and the users complained various problems with the custom ones so i decided to wait for the official release and to install it manually using ODIN!
Now when the officail kikkat is avialable to download i am damn confused about regions i should download from ..coz my PDA version and Csc version denote different regions !
So what i need is some expert advice on this as to what to do in this case when the PDA and CSC /Product code show different regions!? Should i change my csc, den how?n how do i know the correct csc for my device coz my PDA shws i have a multi csc ?(n i dont knw what was my csc before i rooted)
Phone Info
Model:Gt - i9305 4g lte
Country of origin: MADE IN VEITNAM
Original CSC code: VDI
Product Code: GT-I9305RWDVDI
PDA version: I9305XXUEMKC

(P.s- I dialed *#06# to knw the IMEI n through it i came to knw that my phone is from germany so my csc should have code that matches with germany code but my csc code i.e VDI matches to ireland )

So are you having any problems? You can use different PDA(rom) and CSC(sales code) as long as they are from the same android version. It shouldn't matter otherwise. The baseband version will affect your reception and is region specific(ie. What may work well in one region may not work so well in another) If you want stock samsung firmware, the version you install will replace the PDA, CSC and baseband that you have now.

hey thnx for the reply ..
ahan i see ok hmm i sought of got u but still the doubt remains the same which regions firmware should i download now?
My baseband and IMEI denote germany (unlike my CSC which denotes ireland) so should i download the kikkat version for germany or ireland? i reside in UAE so getting firmware of Germany/ireland that wouldnt be an issue ryt?( as i already mentioned the firmware presently in the phone isnt of UAE either n is either of germany or ireland ... so i know geting of a new firmware of these countries shouldnt ceate an issue bt just want to be on the safe side so i am asking u)

So I'm assuming you really want official firmware. I would suggest a custom rom but it's your choice. I don't think installing 4.4.4 official firmware will be a problem, only with the baseband as I mentioned earlier might be a bit hit or miss as it will be chosen for the region where it was released. Also once you install 4.4.4 I'm pretty sure you won't be able to go back to 4.3. The only thing I can suggest if you are certain you want official is try one, then if you face any reception problems or excessive battery drain or something try another one. You are not limited to Germany/Ireland either: By flashing the firmware you download, you replace the PDA, CSC and baseband.

Firstly ya i want the official one coz want to get back my warranty.i know i can unroot to get the warranty back but still i rooted it for being able to get the official fimware on my wish .. but i will surely check with the baseband thing n confirm whether the one i choose will work well i m my region(ie UAE) or not as u said its region specific( that is what u want me to do ryt before proceeding with a baseband Just being sure ..its my first time so want to be clear mate
The question of not being able to go back to 4.3 has confused me like i was willing to back up my current rom so anything as u mentioned arises, i would easily downgrade ! ?
Lastly i am downloading the offical kikkat (from samsung updates.com) so should i back my efs folder and imei as well?any help with that would be gr8

As I've mentioned before when you flash the firmware, everything is included such as baseband
Regarding downgrade from 4.4.4 to 4.3, I have read reports saying the bootloader won't allow you to install 4.3 as it is not compatible, but I'm not sure, I've never tried it. Just google and read as much as you can if this is important(being able to downgrade)
Always have a backup of efs folder on your pc. This contains important stuff such as imei.

gr8 thnx for helping out!

Hi, I have a question. Recently my phone was updated to latest software 7.1 however i wish to return to marshmallow. This firmware that u have available, will it work for my country Trinidad and Tobago? What are the implications for installing a firmware not meant for your country? Also just for confirmation. The firmware software that I am finding does not match my PDA and CSC number.. Will this be a problem?

hello...
please give me some help..
I am beginner on android, flashing and so on...
I have an S4 active, with 4.4.2 with Baseband version "I9295XXUCNI1".
I want to install the 5.0.1 version, but on sammobile, the only version available for "I9295XXUCNI1" is 4.4.2.

Yes, you can install nearly any of the firmwares from the sammobile site. If you're asking which firmware would be the best to flash to your device, it depends where you are located. The NI1 firmware is available for several different countries, so I would flash the firmware for your region, it should be optimized to best work on your networks.

update: I installed the DOD3... it worked!!

When you flash the firmware through Odin it will completely wipe the device, it doesn't matter if you're rooted or not.

thank you

but what if the S4 is locked to orange carrier?
The firmware I have downloaded is carrier free...
is there any problem?

I am afraid of bricking the phone.... I understood the root will not be a problem, but I am afraid of the lock carrier.... the baseband is not the same as the one installed on the phone now
