MOD + Tutorial for Re-partitioning Storage of MTK6589 + Flash through CWM/TWRP

MT6582, ZLR i6, 4GB ROM, KitKat 4.4.2

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.


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 :good:

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

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".

The files you have in your thread are close, but system partition is 883mb.. Which matters a lot, when installing color os...

Will you do that? Please. These are https://drive.google.com/file/d/0B9abLEpf1IGpTGlIcEhHLU4zbDQ/view?usp=docslist_api my current files.

Can someone help me re-partition the system storage of my Micromax A190 please?

I'm trying to use this on a lenovo p780. So far I've been trying for a week to get my full 8 gigabytes back in action on a CN markup. Any help? I've tried flashing this file 3 times already with no profit. Should the EBR 1 and 2 lines have " " or no? Do I need to toss in any other files? Scatter, MBR, pmt?

Tutorial/Guide for Re-partitioning MTK6589 + Increase your System & Data Partitions + Flash through CWM/TWRP + no need to use SPFlashTool

Part 1 :- To Flash existing modified EBR files through CWM/TWRP

There are plenty of guides for re-partitioning mtk devices, so why this one?
Well almost all of them suggest to use SPFlashTool to flash the "EBR" Files.

But we can do that by using CWM/TWRP (Custom Recoveries) as well!!!!!
no need to use SPFlashTool!
no need to format the Internal SDCard through PC!!

Just take your modified "EBR" files and put them into a Flashable Zip.

Edit the "updater-script" file to include the following lines.

Code:

[FONT="Comic Sans MS"][SIZE="3"][COLOR="Red"]package_extract_file("EBR1", "/dev/ebr1"); 
#put the name of your EBR1 file in place of "EBR1"
package_extract_file("EBR2", "/dev/ebr2"); 
#put the name of your EBR2 file in place of "EBR2"[/COLOR][/SIZE][/FONT]

Note :- If your device uses both the files then add both the lines and If your device uses only "EBR1" then add only the line of "EBR1".

Now add the following lines to format your "/system" , "/cache" and "/data" partitions.

Code:

[FONT="Comic Sans MS"][SIZE="3"][COLOR="Red"]
format("ext4", "EMMC", "/emmc@android", "0", "/system");
format("ext4", "EMMC", "/emmc@cache", "0", "/cache");
format("ext4", "EMMC", "/emmc@usrdata", "0", "/data");
[/COLOR][/SIZE][/FONT]

Note :- If you are going to increase your "/system" partition then you'll have to format the 3 partitions,
and if you just want to increase the "/data" partition then just include the lines for formatting "/cache" and "/data".


now save the "updater-script" file and replace it in the Flashable zip!!

Or , you can use this sample flashable zip file.
download it and put your EBR files in it!!!!
edit the "updater-script" file according to your need and replace it in the Flashable zip!!

copy the Flashable zip file to your external SDCard
reboot to recovery
select install from zip file and choose the flashable zip file
Flash it.

Remember after flashing the EBR files do not restore your previous CWM/TWRP Backup.
Just Flash any CWM/TWRP Flashable ROM available for your device!!
Wipe Dalvik Cache if you haven't done it already!!
reboot and see for yourself!!!

Disclaimer :-
I will not be in anyway responsible for any damage this might cause to your phone.
if you'll follow the instructions correctly, then everything will be fine.
