Work in progress to find a Recovery image to install with a Bootable SD Card Update - See How to manually update SYNET7LP/SYTABEX7 to Android 2.2 "Froyo" If this seems simplistic it probably is because of my limited knowledge. I am learning as I go and any assistance is appreciated. There are other forums devoted to development but this site has the most participation related to this specific device. In reviewing many many sources I have made some discoveries regarding this tablet since it has a InfoTM CPU as does the Flytouch II, WOWpad, SuperPAD, Mid Tablet PC, ZT-180, and the disgo Tablet 6000. The tablet has several devices which hold different parts of the file system. These can be identified using these commands. Code: C:\adb shell # cat proc/mtd dev: size erasesize name mtd0: 00200000 00080000 "ramdisk" mtd1: 00600000 00080000 "kernel" mtd2: 08000000 00080000 "resv" mtd3: 0c000000 00080000 "system" mtd4: 3d800000 00080000 "userdata" mtd5: 04000000 00080000 "cache" mtd6: 1ff00000 00080000 "Local-disk" mtd7: 00100000 00080000 "panic" In reviewing a firmware update for another InfoTM device I found this description of the file system. Code: #[alias] [device] [device2] [partition_name] [mount_point] [file_system] BOOT: NULL NULL boot NULL raw KERNEL: /dev/block/mtdblock0 NULL kernel NULL raw RAMDISK: /dev/block/mtdblock1 NULL ramdisk NULL raw RECOVERY: /dev/block/mtdblock2 NULL recovery NULL raw SYSTEM: /dev/block/mtdblock3 NULL system /system yaffs2 DATA: /dev/block/mtdblock4 NULL userdata /data yaffs2 CACHE: /dev/block/mtdblock5 NULL cache /cache yaffs2 LOCAL: /dev/block/mtdblock6 NULL local /local yaffs2 SDCARD: /dev/block/mmcblk0p1 /dev/block/mmcblk0 NULL /sdcard vfat TMP: NULL NULL NULL /tmp tmpfs PACKAGE: NULL NULL NULL NULL package This now explains why attempts using unyaff to open the image file created by dumping mtd2 have failed. Using this HOWTO: Unpack, Edit, and Re-Pack Boot Images The extracted ramdisk image from the Sylvania reveals the following file structure which will look familiar to anyone who's examined their device layout (image below). So we know that device mtd0 is in fact ramdisk. In this post Firmware update 1480, instructions and download link, from a developers forum, they provide a link to a firmware of a similar device which includes instructions and utilities to create a bootable SD. Using the provided instructions and utilities from the downloaded file, I was able to create a SD card that boots! A 2 GB microSD was re-sized to 705 MB and the included "aben.start sector.001" file was incorporated into the "Clone Disk". It was then formatted FAT 32 with Format options - Quick Format checked. I copied only the uImage and userdata.img files to the card and inserted in tablet. Powering on the following was displayed. Booting from SD ... Burn file system finished Take off SD and reboot. Nothing was changed or burned in the process above. This was only a test for creating a bootable SD card that will work in this device once we have the correct image files. The test process DID NOT affect the original ability to do a complete factory reset. This as far as I have been able to take this effort. Any further insight to which of the images pulled from the Sylvania, if any, can be used in place of the images provided by in the example from the other device would allow creation of a working SD recovery for the Sylvania. A complete victory would be to find the magic combination which will all those missing an Recovery to successfully recover from SD. Where do we go from here to find/create the correct files for the Sylvania?
