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.

Exclamation Need help on some confusions.
Sir,
I am using micromax canvas 2 colours a120 with 8gb rom (mt
6582). I am using TWRP recovery.

I have a lot of confusion about android backup and modification. I
have searched a lot in google, have read a lot of xda forms but did
not found proper answer of the following questions.
I am very sorry for asking so much question.
But I shall be very very much greatfull if you clear my confusions

1) Can TWRP or CWM backup EBR files while nandroid backup? (I know
that mtk droid tools and sp flash tools readback can do that)

2) Where preloader.bin get saved in root explorer?
(while scatter loading through sp flash tools we find preloader.bin
which we should untick before download. Other wise phone may get hard
bricked. So i want to know where it remainis in root explorer. So that
I do not modify it by mistake.

3) May some custom room need modified preloader.bin? (I shall not
flash custom rom if it need modified preloader.bin)
4) Can recovery be accesed and nandroid backup be restored after wrong
flashing through modified recovery ?

5) Is there anything other rather than preloader.bin that I should
untick while flashing through sp flash tools?

6) Does the apps that changes app storage and internal sd size (like
hkromeditor.apk mlpriorepartition.apk)
Only flash Ebr files or they also modify preloader.bin?

7) Does imei, bluetooth , wifi automaticky backuped by TWRP Or CWM in
nandroid backup? (we know imei remains temporary in nvram and
permanently in system\etc\firmwere\modem.ing)

8) If I loose imei and bluetooth or wifi will nandroid backup will
restore it? (I have also mobiuncle tools backup and mtk droid tools
backup)

9) Where Ebr files remain in root explorer?

Please reply. Sorry for asking so many question and for improper english.

NOTE "If you are not developer do not reply unless you know properly".
