I only got my i9300 yesterday so this info is not complete and COULD contain errors, this thread will be updated as and when I find other info out.

As listed on this thread, the US version.

The use of dd;

dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p18

Where as the Asian variant of GS3 is on different block 0p6 instead.

Is it a normal practice to writing the recovery.img by using dd?
Or was it just used purely to escape from increasing the flash counter?!

GT-I9300_mx_20120329.pit can used for 32GB(S3) ?

You have 32Gb SGS3?

If so contact me via PM and we can read your current pit and check.

Blindi1985 · Jun 30, 2012

Which *.pit-file is correct for the 16GB Version?

GT-I9300_mx_20120220.pit
GT-I9300_mx_20120322.pit
GT-I9300_mx_20120329.pit
M0_20120220.pit
M0_20120220.pit

Why do you feel you need to flash with a pit file?

ZACQ8 · Jul 1, 2012

A noob Question, Can we access OTA partion, the OTA file which is downloaded can be accessed before flashing it?

The OTA files are stored in the cache partition, check it out with root explorer

sacredabyss · Jul 2, 2012

I'm just being nooby, what does this thread do? will it later become a rom?

E:V:A · Jul 2, 2012

It would be useful and interesting to know what is inside and the function of the various partition images. For example, why is there a cache image? I would have assumed the default cache.img should have been empty.

In addition what is the "new" TZSW partition? I've never heard of this one before. Finally, is the GT-I9300 PARAM the same as for I9100?

ARM Trusted Zone

Function is the same but format is different, i9300 file is a tar.

mmcblk0p4 PARAM = param.bin = param.lfs
mmcblk0p5 BOOT = boot.img = zImage
mmcblk0p6 RECOVERY = recovery.img = no
mmcblk0p7 RADIO (MODEM) = modem.bin = modem.bin
mmcblk0p8 CACHE = cache.lmg = cache.img
mmcblk0p9 SYSTEM = system.img = factoryfs.img
mmcblk0p10 HIDDEN = hidden.img = hidden.img
mmcblk0p11 OTA = data = data.img
mmcblk0p12 USERDATA = userdata.img = UMS.img

SGS3 32GB Internal memory

If guys u need any kind of help. Soooo most welcome

@odia

Thanks for the infomation about mmcblk0p4 (param.bin).

There are 26 jpg images in this partition - one is the boot logo.

I replace the boot logo (logo.jpg) and reflashed mmcblk0p4, but the original boot logo is showing.

Do you know if there is a backup of this partition somewhere?
Or, if the logo.jpg (boot logo) is in the SBL partition?

I know I flashed it correctly, as I copied it back and dumped it. It was as I created it.
BTW - I had no errors on boot because of my changes.

Edit: I did clear the cache

Thanks.

Yes logo.jpg is also part of sboot (sboot has 8 JPEGs) so that must be taking over.

I have a 32gb S3 unlocked and rooted if you need any information.

Since SGS1, thru SGS2 (although not recommended by devs) I always flashed lowship firmwares (with data.img) and pit. Just to be sure that everything is overwritten... If I had data.img (userdata) I could do with SGS3 as well...
