Hello dear RIFF Box users !
In order to diagnose possible problems with mass memory chips (internal
disk) in above listed models, we've added ROM2/3 chip detection to DCC
loaders.
This applies to following models:
- Samsung Galaxy (P1000/i9000/T959, m110s, m180s)
- Samsung Nexus (i9023, i92020, m200s, m200k)
Explanation:
Above listed models have two memory chips:
- NAND chip which holds bootloader and part of system software (ROM1),
- eMMC chip which holds user data and in Nexus phones complete OS (system software). (ROM2 and ROM3)
In case that eMMC is faulty, Galaxy models will hang on startup screen, or show message "Unable to mount x drive",
Nexus models will not start at all, or just will show black screen with low backlight.
To diagnose if eMMC is faulty or not, use the following method:
- Galaxy models:
Select P1000 DLL, and on DCC TAB select ROM2, set any data length size,
click "Read Memory".
If You get "error 0x28" on reading attempt, it means that eMMC is faulty and You have to replace it.
- Nexus models
Select i9020A DLL, and on DCC TAB select ROM2, set any data length size,
click "Read Memory".
If You get "error 0x28" on reading attempt, it means that eMMC is faulty and You have to replace it.
Examples:
Here is sample log from P1000 with working mass memory:

Here is log from device which has faulty mass memory chip:

In this case mass memory is either not present or it developed failure. Only NAND chip (ROM1) functions will remain accessible.

In this case eMMC is also faulty, and need to be replaced.
