Of course! Excuse me
I will attach the dumps now!
BTW bit 0x6D51 is 0x00 now
But i will double check (maybe that i forget to set it back to 0x01 when playing around with SoC EEPROM before)
Edit: I'm going crazy! That's my run_old.sh which is executed because run_old.ok is created:
Code: Select all
#!/bin/sh
dd if=/dev/bml0/10 of=/dtv/usb/sda1/bml10.dmp
date >> $1/run_old.ok
echo $1 >> $1/run_old.ok
#ls /mtd_rwarea/usb_mount >> $1/run_old.ok
#cp /mtd_rwarea/usb_mount/killself.sh $1
#cp /mtd_rwarea/usb_mount/usb_cmd $1
#cp /mtd_rwarea/usb_mount/usb_mount $1
#cp /mtd_rwarea/usb_mount/usb_hotplug.sh $1
rm -f /mtd_rwarea/profile
sh -x $1/SamyGO/rcSGO $1/SamyGO > $1/rcSGO_out 2>&1 &
But there is no dump file on the usb stick
Edit2: changing to 'dd if=/dev/bml0/10 of=$1/bml10.dmp' has no effect too...

Code: Select all
mount | grep "sd*" >> $1/run_old.ok
is the answer /dtv/usb/sda1 ?
edit: Try
Code: Select all
dd if=/dev/bml0/10 of=/mtd_swu/bml10.dmp
cp -f /mtd_swu/bml10.dmp /dtv/usb/sda1/
or
Code: Select all
bml.dump /dev/bml0/10 /dtv/usb/sda1/bml10.dmp
or
Code: Select all
cat /dev/bml0/10 > /dtv/usb/sda1/bml10.dmp

Finally...
'mount|grep "sd*" > $1/run_old.ok' returned:

'bml.dump /dev/bml0/10 /dtv/usb/sda1/bml10.dmp' didn't work, but cat command did!
Edit: inconvenient dump sizes BTW... had to delete bml10.zip which you already downloaded as only 5 attachements are allowed

okey, waiting for other.
ps. i hope here is enough time to make dump of /dev/stl0/17 ?
Code: Select all
cat /dev/stl0/17 > /dtv/usb/stl17.dmp
or first to /mtd_swu and next reboot - copy to USB

bad, only bml9 and 10 are complete, other partitions have just ~1Mb of size
Edit. need to know how to calculate hash of current /mtd_exe, time is not enough to reflash full partition

Have to disappoint you: stl17.dmp copied from /mtd_swu is only 976kB...
Do you know how long a flash of /mtd_exe takes?
Is there any way to prevent sstem from shutting down (kill auth**)?
Edit: to see what file a touched (timestamps) on /mtd_exe 'ls -lsaR' would be fine, wouldn't it?!

flash of exe.img takes longer than you have time. Do you let TV boot with USB attached OR are you attaching USB after a while after TV is powered on?
Leave it for coldstart and let it dump bml0/5, we need more time.
Here is nothing what prevents TV from reboot by authuld, just correct hashes.

Is attached before boots.
Look, what i figured out:

As suspected the rc.local is corrupted. What about setting time whith date command to Oct 10 2011 and create new file with correct content? And then toggling partitions back

You could try to replace correct rc.local from original exe.img same way like you changed it.
mount as rw and bla bla bla. But now you don`t have much time. And not much hope that in this case hashes will be correct.
Not create new file, but use original file!

I will try that! Could you extract the rc.local from T-VALDEUC-3011.0? (have no linux here to mount)
Why should the hashes not be correct after copying the original file? Because of the timestamp?
