Core partition - How to re partition the OFW core

[vizhigal]

@Die Dont flash any newly created core. I have not added the final modification in my msg. Will give you.

[vizhigal]

@Arya My CFW ROFS2 is just 82 Mb compared to normal CFW ROFS2 109 Mb. I was only asking how to make a CFW  core with a size of 43.9 Mb from  OFW core of 110Mb.

[Aryacooldude]

Because the size of your ROFS2 is exceeding the size of ROFS2 given in the core .

Refer my first size details

My brain is all up now

By deleting the contents in rofs1 u can achieve tht size but the problem is rofs2

ok, anyways, i need not worry. . .my phone is stil under warranty

i cud do any tests widout any fear

Now we can disable the protections in the Core and ROFS2 too.

As per my info Binh24 edits the C00 file and move the Rofs2 from it so that C00 file would contain nothing but the info regarding phone and its hex codes + some required files (No app would be present in it) hence he get the core size at below 40Mb size

He deletes everything from rofs except one file

Deleting ROFS1 from .C00 file will not give a repartitioned core. Core file contains information about sizes of the  CORE ROFS1 ,ROFS2 ,ROFS3 & UDA. The sizes need to be modified  core .C00 file. Then ROFS2 file need to be modified with the amended size. The attributes need to be changed from 2B to 2A. The OFW ROFS3 need to be copied and to replace ROFS1 in the Core C00 file. The table need to be adjusted . Then only we will get the repartitioned core ready for flashing.

[Aryacooldude]

The OFW ROFS3 need to be copied and to replace ROFS1 in the Core C00 file.

Why??? itz not needed

[vizhigal]

In the core .C00  file  the ROFS1 size  71,703,996 bytes is  reduced to 1,048,576 bytes . To accommodate 1,048,576 bytes the ROFS3 portion was added to the Core.C00 file. That is why  while flashing ROFS3 file was not used. The above is true in the case of PNHT core. First post updated.

Well now itz not mandatory we dnt need to place ny files just one dummy file is enough

[vizhigal]

Now because of the tools available we do not require any file in ROFS1. When PNHT done the first core partitioning this was the case. Again if you place one dummy file in the OFW core .C00 file , the modified core file can not be used for flashing because partition table in the .C00 file and partition table in the ROFS2 file need to be modified. First post updated with partition details.

WAS unaware of this thanx for the info +1

Thanks.

Binh 52.0.101 CFW core contains ROFS3 files.

He has used v 52.0.007 ROFS3 files instead of 52.0.101 ROFS3 files in his CFW.

This is clear that ROFS3 files needed to replace ROFS1 files in the core .C00 files.

This can be compared as below using Sweatscape 010 editor.

Compare 1 & 3 to know that he replaced ROFS1 with v 52 .0.007 ROFS3 files

Compare 1&4 to know that CFW ROFS1 files are changed with respect to OFW.

Attached the below

1.binh-RM-356_52.0.101_rofs1.bin ( Just extracted ROFS1 for comparison because of file size )

2.RM-356_52.0.101.502.02.rofs3.bin

Well he didnt place ny files in 5230 rofs1

Thts why I thought tht nw we dont need the lame themes

[vizhigal]

I have analyzed starting from PNHT RM356 51.0.006 CFW core till date RM356 CFW core including new Chineese core with out adding ROFS3 part to OFW .Coo file. But they removed 0xSD sectors in ROFS2 files. Because they want to remove the SHA1 20 byte protection .

[Aryacooldude]

Well little confusing

[vizhigal]

Its all because Nitesh who has asked me about Core partition . I got involved and the thread is because of this, But it is interesting if you involve yourself  and compare the files. Finally you will know  how to make a CFW

OOooh...+1 for the info

[Aryacooldude]

Well Lets summarize!! U need rofs3 in .C00 to flash right!!!

Cool

+2 Vizi...got to know many things about core

[vizhigal]

Well Lets summarize!!

yes , If the CFW to be made in the PNHT way

NO . If the CFW to be made in the new Chineese way ( with their tools )

K i get it now.

With No editors they did a heck of a job

Really tht group was epic and all r off now now only adonix is active(the God of Porting has returned)
