This is a place holder for where I will do a write-up on all the released and unreleased progress I have made and any other helpful tools, sources, and patches I have made.

CWR for infotm(ic) / Sylvania:
Hey look, I actually finished it:
NEW FEATURES:
No more need for an external keyboard
Fixed the warnings and mount issues
More ui candy
Background code for ota updates (in future)
various other small tweaks
Here's the new recovery ramdisk [3/27/12]: http://min.us/mbjJ9i3KhK
Flash it with iuw as RECVRD.
If you cant find the button combo for your model to boot recovery, then you need to root it, install a terminal and type su [enter] reboot recovery
Tested on Sylvania 7" (sytabex7) and iCan 10"
sdbootable method coming soon for devices that lost otg mode.
Rom Manager should be able to reboot recovery too. But before you go messing with it trying to flash roms, be warned this has access to all partitions of the device (including boot) I'm not liable blah blah blah.

Bootable sd maker:
The following download is a largely compressed archive.
To open it, you will need to download 7zip (or use linux ;] )
After you decompress it you will have two files.
1) newsd.img (roughly 1gb)
2) hddrawcopy portable exe
You will need one micro sdcard you dont particularly care about.
Preferably a 1gb card. This should not be your regular use sdcard, since if you forget to remove it, you will end up reflashing your device when you turn it on.
Once you've found your sdcard, be sure you empty it since this will completely erase the card.
Regardless of what size card you use, (1gb - 8gb) you will end up with only 705-740mb of space left.
Simply use hddrawcopy to burn the newsd.img file to the micro sd via a card reader, then eject the card and reinsert it. The new filesystem will contain one folder named android which includes a readme and a flashable copy of the recovery ramdisk. If you have a copy of your stock ramdisk, you can trick recovery into booting automatically like so:
1) rename your ramdisk.img to ramdisk.img.original
2) rename recovery_rd.img to ramdisk.img
3) eject the card
4) flash to the device
5) rename files back
6) eject the card
7) boot device, recovery automatically opens since its the main ramdisk now
8) after backup/restore use the card to flash back the original ramdisk.img
ALWAYS REMEMBER TO SAFELY REMOVE / EJECT THE SDCARD
As I've said before some tablets (like the 7lp or some disgo's with the updater layout instead of recovery) will not boot with the recovery flashed and will required either an ius recovery or sdrecovery (by using the system, userdata, ramdisk, and uimage files extracted from your ius via iusedit) REMEMBER, you don't ever want to touch u0, I know its in the stock ius, but you never need to reflash it. EVER. The fact that your device still turns on is proof you should leave it be.

Code:
README:
THESE FILES WERE DISTRIBUTED ON ANDROIDTABLETS.NET AND TECHVENDETTA.COM
These binaries are gpl, however, the system images you build using them are not. (proprietary files)
I'm not responsible for your use and or misuse of these tools or what you attempt to do with their output.
32bit binaries:
USAGE:
chmod +x mkyaffs2image
./mkyaffs2image -c 4096 -s 128 -f system system.img
Your working directory should contain the binary mkyaffs2image and a system folder to work with. If dumping from device,
you must tar.gz the system folder before placing it on sd to preserve the symlinks. -f tries to fix them but sometimes cant.
If you have an ius file, to get system.img use the ius editor found here on androidtablets.net, then:
chmod +x unyaffs4k
./unyaffs4k system.img
this dumps the contents of /system/ into the EXTRACTING_SYSTEM folder.
Next you need to copy everything into a folder named "system"
make your changes, and rebuild.
ALSO NOTE: you need a filesystem that supports symlinks so dont try this on a fat or fat32 partition.
any questions at all, just send me a pm @ TechVendetta on androidtablets.net
Also, once you get the hang of working with this stuff shoot me a pm and maybe I'll add you to my DEV circle on g+
