@duvelr, Nice one, thanks - So we know now all the correct nand partition names, (we were close before).

Code: Select all

Nanda = BOOTFS
Nandb = LROOTFS
Nandc = LSYSTEMFS
Nandd = LDATAFS
Nande = MISC
Nandf = LRECOVERYFS
Nandg = LCACHEFS
Nandh = UDISK

[duvelr]

Then maybe we can start putting together a set of 'adb' commands to create a 'recovery' file? Before Trying Anything Else that can taint the system!

For mount points and 'fs' see /init.sun4i.rc, /uventd.sun4i.rc & /proc/1/mountstats also
the output of the 'mount' command can be informative.

how did you do the command on boot as if i reboot it unmounts from adb and cant type the commands before boot starts s get no nand patitions in results?

any other usefull commands would be appreciated as still got lots to learn about android and linux

[duvelr]

humm ... I did get suspicious when dmesg didn't get me the full record.

Ok I've been playing with this for a while and here's another -awkward- way to get it:

1. switch off tab.
2. in terminal (PC/Mac/Linux):

Code: Select all

adb shell cat /proc/kmsg > kmsg.txt

3. switch on tab.
4. repeat(Key-Up & Enter) until no longer receive the message "error: device not found"
5. Ctrl-C to stop.
6. Edit kmsg.txt

hoorah that did it

Very pleased to see you happy!!

And here is the best way I've found:

1.

Code: Select all

adb bugreport > excel_bugreport.txt

Wait for the prompt to come back.

2. Edit excel_bugreport.txt and search for the string "------ KERNEL LOG (dmesg) ------"

I'm back in a week.

gonna try that now, when you get back maybe work on getting an update .zip made for this 2.3 if you have the time. i have all the nand blocks here would like to get an update.zip signed so we can easily flash back to stock 2.3 from an ICS rom. or other members can flash my older firmware version from stock recovery without having to go the CWMOD5 route to get a better video lypsync.
cheers
