Well he has been told that the repair would cost him 150 dollars minus the replacement eMMC chip.

Is that a rip-off? We've seen guys replace and solder the new eMMC in like 20 minutes on youtube.

Considering what a high-risk delicate operation it is and how much specialized equipment is required - no.

You guys are seriously better off just buying a new phone at this point if your phone is dead. It's just not worth it. Sell it for parts (the screen w/assembly alone will get sell for around the cost of a new S3). Sell the SIM/MicroSD card reader combination. Sell the body of the phone. You might be able to sell the mobo for parts to someone who has experience. Just list it all on eBay and then buy yourselves a new phone with the money.

Stupid question...

Someone checked Tizen stuff?

Test device RD-PQ has I9300 pba inside...
Not sure if Live Demo Unit... but I9300A visible on Label...

Maybe checkout s-boot-mmc.bin ca. 290 KB...
http://download.tizen.org/releases/system/

Sources for uboot are here:
ftp://ftp.denx.de/pub/u-boot/

For instance u-boot-2014.04-rc1.tar.bz2

Samsung folder inside...
TRATS is S2 related...
TRATS2 is I9300 related...

I think RD-PQ is 16 GB variant...
Partition table is inside u-boot-mmc.bin
Attached...
IS unsigned or I have not seen Signature...

I9300 retail ignored this PIT...
I think because missing Sig...

Please, I am new to I9300
And I have only 1 damaged device with damaged Display, so I can't see nor Touch working...
So I was not able yet to dump few first Bytes from eMMC...

My obsolete knowledge about 512 Byte MBR + partition table... is from S8500/I9000...

For instance S8500 has 512 MB OneNAND and 1960 MB moviNAND... something similar like eMMC...

OS stores additional info into this MBR...
Code:
2NDFORMATCOMPLETED
2NDRSTORECOMPLETED
PRODUCTCODEINVALID
If NAND/Headerinfo is alive in OneNAND...
Instead text PRODUCTCODEINVALID is Unique number written...
sysinfo related...

I can not find I9300 dump to compare.
Maybe someone can help me to find Link or maybe someone can upload please first 512 Byte for study.

Thanx in advance.

Best Regards

I wonder if the previously mentioned eMMC low-level format command can be used to remove Knox from the i9305 (& possibly the i9505 as well)...

EDIT: Suggested procedure:
-Make a full Nandroid of all accessible partitions (including EFS).
-Prepare SD card for bootloader repair. (Does this still work if the entire eMMC is wiped, or does some boot partition need to be preserved? If not, use JTAG.)
-Do a low-level format.
-Restore the bootloader from SD card or JTAG.
-Flash param.bin, and restore EFS, ROM and user data.

So what is it? Because, I sure as hell have no idea why'd you bother making such a post without further explaining yourself.

I think this would work. SDC3 fuse is burned, so it should boot fine as long as the GPT and properly signed images/partitions are in place.
