Hi,

veery nice tutorial, but onlu problem that I have is that on my phone, System is P6, Cash is P7, Data is P8 and Internal SD is P9.

So, there is no explanation for EBR1 and EBR2 for this way of partitioning.

i have similar phone, i try follow your instruction but its still nonsens for me. Please see this hex code and help me, maybe i was wrong and you can correct me.

first i think we have different name of partition so i can't use your guide instantly.

Code:
MBR
00 00 00 00 05 00 00 00 | 00 04 00 00 | FF FF FF FF
00 00 00 00 83 00 00 00 | 00 68 00 00 | 00 50 00 00         ->   20000 =  10240000 > 10mb  
00 00 00 00 83 00 00 00 | 00 B8 00 00 | 00 50 00 00         ->   20000 =  10240000 > 10mb
00 00 00 00 83 00 00 00 | 00 6C 01 00 | 00 30 00 00         ->   12288 =   6291456 >  6mb

EBR1
00 00 00 00 83 00 00 00 | 00 98 01 00 | 00 40 06 00  -systm ->  409600 = 209715200 > 200mb
00 00 00 00 83 00 00 00 | 00 48 08 00 | 00 00 18 00  -cache -> 1572864 = 805306368 > 800mb
00 00 00 00 83 00 00 00 | 00 48 20 00 | 00 D0 0B 00  -data  ->  774144 = 396361728 > 375mb
00 00 00 00 05 00 00 00 | 00 F4 07 00 | FF FF FF FF  -link int-strg

EBR2
00 00 00 00 83 00 00 00 | 00 24 84 00 | FF E7 73 FF  -end
how can i ensure partition name? my phone is 8gb, it should have 1gb++ on data or system but i dont find it.

Superb Tutorial
Thanks a lot for the tutorial. It is really helpful to thoroughly understand MBR, EBR1 & EBR2.

I modified stock EBR1 & EBR2 using HxD and flashed using SP Flash tool. Failed once and read the instructions again then found my mistake.
Corrected it and yes, it worked like a charm! I am using MMX A190 (MT 6592), increased /data to 4GB and rest to internal SD.

Using for more than 24 hours, rebooted couple of times and working fine.

Thanks again

Note: I didn't have any option other than using CWM backup. I restored CWM backup after formatting /data. Somehow it is working fine.
