Once a tablet is manually updated we have found on another tablet a complete copy of the multi-part update file (.ius) is stored on a partition. By extracting the data from that partition a user could save the file for recovery if ever needed to burn the update again.
Some of this information was discussed starting around post #86 in the Custom Sylvania ROM development thread.
We have confirmed on another tablet the mtd2 "/dev/block/mtdblock2" partition is in some way a Recovery partition containing a complete InfoTM Update Wrap file which could be dumped and saved to use in case the device needs to be manually updated. We just need to ensure we keep the update file complete so it can be used with the InfoTM Update Wrap tools (IUW.exe).
Using either adb or Android Terminal Emulator could you obtain a copy of the mtd2 partition "resv" (mtdblock2) using the following command and post the resulting 128M for inspection?
If you aren't rooted or not interested or able to perform any assistance with obtaining from another AIRIS OnePad 700 tablet owner would be appreciated.Code:dd if=/dev/mtd/mtd2 of=/sdcard/mtd2.img bs=4096
