Hantek DSO1152S - Wont boot after firmware update

<< < (8/26) > >>

WanaGo:
[root@Hantek /]# chmod 777 *
[root@Hantek /]#

hmm

Also in that rcS file, it looks like it is still looking for dso_update.exe ?

this is exactly what i sadi, Hantek implemented that check into rcS but since i don't know when exactly, they overwriting the running dso.exe with new one during firmware update (which never works on my systems). anyway, this is not the point here, leave that as it is.

All you can do now is try again to:
- kill dsod (in case still there, but you renamed it so should be ok now)
- kill dso.exe
- copy the new dso.exe into /
- in / chmod 777 *
- rm /param/sav/r*
- power cycle DSO and watch what is doing

in principle it have to work now. If now tell me what you see (segfault again? is something on screen/key reaction?)

WanaGo:
Its still the same.

Boots the first logo, 2nd logo, then goes black screen.

UART just outputs the same stuff:

Sits there, black screen. Doesnt boot into dso.exe

tinhead:
hmm, do you want to try to downgrade te firmware?

here on my onedrive http://1drv.ms/1hf4SgO
you will find in "DSO hacks->firmware->hw1.00.4" older fw versions.

While downgrading all you have to do is to copy to your DSO is then the dso.exe and English.lan from the older
firmware version (so you have to use gpg, winrar again to get them).

killall dso.exe
cd /
cp /mnt/udisk/dso.exe /dso.exe
rm /OurLanguages/*
cp /mnt/udisk/Engish.lan /OurLanguages/
chmod 777 *

WanaGo:
Ran the last command from the rcS file manually, to see what happens

Which is what I get on the UART when it does it itself.

running ./dso.exe works fine.
