Supported files Z3X shell

[Jane1]

I started with eMMC learning. As a test I want to program firmware for i9300.

My eMMC chip is like this

I found out that there 4 Supported files possible to download from Z3x shell.
There are
EMMC_ROM1_512Mb_USER.rar and EMMC_ROM2_2Mb_BOOT.rar
So I guess they are for eMMC. I unpacked them and started with EMMC_ROM1_512Mb_USER.rar

I set:
ROM to access ROM1( Main user data)
Preset I left it for 128kB How should I set it?

Next I wanted to programm ROM2
but it failed
Checking NAND Image : C:\eMMC\i9300\EMMC_ROM2_00000000_00200000.bin
Autodetected RAW data
File successefuly loaded!

Partition table scan:
GPT: not present

Why does it fail? What is GPT?
Thanks?

1) update you eMMC to last firmware, 0x8 old and no stable, stable is 0xF7, 0xFC, latest is 0xFC.

GPT - Partitotn table, first 0x4000 bytes of ROM1

You need select file, select ROM (1/2/3), press write
or Set "Write All ROMs" and select multiple files

Preset need to set "Lenght" address.
Then you load files, "Lenght" is auto changed

Thanks for the reply.I updated firmware. At the end of the updating it says
Please don't forget to repair extCSD from backup!
Please don't forget to configure BOOT sizes!

Will it be done automatically when I upload ROM1 and ROM2?

Next I Set "Write All eMMC regions at once "

As you can see there is a problem with ROM1. Can you please help/explain?
Thanks
