[Samsung Galaxy Tab A series Guides, News, & Discus] bojan.1995:
Hey,

I successfully unbricked my device.

Follow this, it's very safe since you are flashing Stock Rom.

In order to get your CSC regional code you need to contact Samsung. This is really boring since you will have to deal with multiple agents from customer support.

I first contacted Samsung US via Live Chat under support... and they didn't provide any details about product Region at first. So I contacted them few times until they helped me.

YES SPAM THEM AGAIN AND AGAIN.

DONT EVEN SAY YOU ARE NOT FROM US AND DONT MENTION HARD BRICK OR ANYTHING.

So, according to them, my device is for Germanic region (I already knew this, I had some HSH Hotel bloatware).

I contacted German support via live chat and my device is from Austria.

VOILA.

Now that I know which region it is I need to check CSC Region Codes and I made a list.

I searched for them online until I matched codes on the left and Telecoms (carriers) on the right.

Austria (csc codes are on the left and Telecoms on the right):

CSC Regional Codes = Telecoms

AOM = AUSTRIA - unknown /generic probably

MOK = AUSTRIA - unknown /generic probably

TTR = Austria - magenta (former telering/t.mobile)

TRG = AUSTRIA - TELERING

MAX = AUSTRIA - t-mobile

DRE = AUSTRIA - Drei 3 (former Orange)

ONE = AUSTRIA - Orange

MOB = AUSTRIA - a1

ATO = AUSTRIA - Open Austria - directly from Samsung

So, I contacted Drei 3 and A1, I spam them a lot and eventually both agents answered my device is not on their list.

Since my device was

SIM UNLOCKED

I decided to flash ATO since it's Open and directly from Samsung

AUSTRIA

.

FIRMWARE

Caution, I didn't like 7.1.1 since I want Root.

So I flashed 5.1.1.

So now that I know which CSC Firmware I want to flash I have to download it. Yes, Firmware is same terminology for Stock ROM.

I downloaded mine from

GALAXYFIRMWARE .COM

You could download older firmware if you want, I flashed both for

TESTING

I had firmware 7.1.1 and that one I downloaded.

7.1.1 ATO

Then I downloaded 5.0.2 ATO

Choose which one you need.

Then Extract zip in 1 folder.

ODIN

Download unpatched

I leaved

CHECKED

AutoReboot and F.Reset

FLASHING

FOR 7.1.1

Now, every file from extracted zip make sure it matches Odin box:

BL file is going into BL slot

AP file is going into AP slot

CP file is going into CP slot

CSC file is going into CSC slot

For 5.0

There will be only 1

It goes into AP slot

Now make sure your Tab is turned off.

If not, remove back cover and unplug battery and plug it back again.

Press Home + Power + Volume Down

(at the same time)

When prompted blue window, press Volume UP

Now connect it to Odin and wait 2minutes to connect.

Start flashing.

If it fail you are flashing wrong FIRMWAR. HAPPENED TO ME FEW TIMES.

PIT FILE

USE This if ABOVE FAILE.

I did not test this.

Okay for some reason you are really in bad position and you really want to flash PIT.

Well you can extract Pit from 7.1.1 CSC.

Copy CSC file to Desktop and rename it to .zip extension:

It will look something like this:

Now extract it and look for Pit extension file.

Its something like:

NOW make sure in ODIN Re-Partition is CHECKED.

Now that you have it and you are flashing with PIT.

IN ODIN THERE IS PIT OPTION CLICK ON IT.

IN PIT SLOT PUT PIT.

IN OTHER SLOTS PUT OTHER FILES FROM EXTRACTED ZIP.
