Sorry, first of all my system could not type in Chinese, it's really appreciated if somebody could translate this to Chinese so more people could read this.
The attachment in download link from "benq e72 wom 6" contains an invalid E72 rom!!!
DON NOT TRY TO FLASH THIS IMAGE BACK TO YOU E72 BY ANY MEANS. OR YOU MASS YOUR PHONE UP.
Why I think the rom file is incomplete? Good question!
1, I'm using Utils which reads the Disk on Chip partition to analyze layout of E72 rom on a living phone.
2, E72's D.O.C. Partition reads as follow: 79.92M (0x4fec000) DSK1: | 1.19M (0x12fc00) Part00 | 2.56M (0x290000) Part01 | 76.17M (0x4c2c000) Part02 (The first partition is boot, then XIP and IMGFS )
3, So the flat binary file dumped should around 80m in size, which 20m larger than attached.
4, If the rom is proper dumped, a 4 bytes signature/checksum could be found at the end of it.
5, In addition, I've spent some time on the attached rom try to extract and modify it. The result is: so far I could strip the main file system part out of image and extract files from it accordingly. But the tools will just crash at certain point for unexpected end of file problem (this usually caused by an incomplete rom)
And feel free to reply in Chinese, I have no problem to read Chinese
