As
Mark Nord say, "um recovery" still works... I'm still using the old firmware so I cannot try it, but I think that "delete" and "fulldmp" are also gone...
And I think there is a key combination to boot in recovery mode, but I don't know what one
(I've tested it and it didn't work for me, but it's possible that I've tested it
before enable adb... and I think it only works after that, as you have the new boot that porkupan has kindly make for us...

and now that I've enabled adb, I can't remember the combination

)
uboot
I'm very busy theese days... Feel free to put this info in the wiki... or I'll do it when in I can...
I think this is the first thing that everyone have to do with a new T1 (their own backup of their own partitions)
As a matter of fact:
- I did that
- I make a backup of every partition... not only system & data
- I've mounted every image into a new /tmp folder
Tip: To know the kind of image to mount "-t" option, you can do "file *.img"... It tell you if it is FAT, EXT, CRAMFS,... and a lot of usefull info
- I've make a ".tgz" of the contents of each image (so I can view them easily in windows, and I can recover specific files from adb)
- I've extended the system partition to maximum (I don't want to tell how as I'm speaking by heart and is a dangerous operation... but I'll write it to the wiki when I'm sure... I've not used the same method as boroda/porkupan... It was based on "resize2fs")
- I've deleted all unusefull android packages and changed some permissions
- I've installed su, Superuser.apk and the last busybox

As you can see, it's a very usefull procedure...

I've did it this way because porkupan doesn't have any packages for my firmware version... and I always like to learn "my own way", if possible...
