HT-D5550 brick (exeDSP)

[keksnase]

Hello,

it seems I have bricked my BD Player

the steps I've done:
updated to patched Firmware 1116 (http://wiki.samygo.tv/index.php5/Patche ... NS_service)
installed samyGO Extensions Pack via smarthub
with this guide (http://wiki.samygo.tv/index.php5/ExeDSP_modifications):
downloaded latest firmware,
extracted exeDSP,
decrypted,
patched with freepatcher,
uploaded to /mtd_rwarea/ (chmod 755 via filezilla),
copied /mtd_exe/rc.local to pc,
renamed it to user.sh and modified it like this:

SpoilerShow

echo "B-FIRHTBEUC" > /dtv/info
echo 7 4 1 7 > /proc/sys/kernel/printk

mv /mtd_rwarea/user.sh /mtd_rwarea/user.sh.safe

if [ -e /mtd_rwarea/myBoot.sh ]; then
/mtd_rwarea/myBoot.sh
else
mount -o bind /mtd_rwarea/exeDSP /mtd_exe/exeDSP
cd /mtd_exe
sysctl -w kernel.msgmni=64
./exeDSP
fi

copied it to /mtd_rwarea/ (chmod 755 via filezilla)

rebooted -> see photo

is there anything I can do?
I cannot find a way to open the service menu. is there any?

this model has no vga port, only usb. (see http://img.hifitest.de/blu_ray_anlagen_ ... 965348.jpg )
I've read about ex-link but i'm not sure what I need.

I found this page: http://wiki.samygo.tv/index.php5/Serial_console
so I guess I have to identify the correct resistors...
Is there anybody who could help with this task?
I will upload pictures this evening if this helps...

please help!
thanks for answering

[keksnase]

thanks for the reply
I'm at work so I cant test properly right now, but if I understand the topic correctly I can plug an usb stick with a run.sh to my bd player and it will be excecuted?
thats great!
if I remove my user.sh and exeDSP everything should be fine, or do I have to format my rwarea like it is described here: viewtopic.php?f=57&t=5443&start=30#p39459

thanks again for the reply! maybe there is still hope

I am in doubts, but try and tell us result. If usb is initialized BEFORE exeDSP and hotplug hack is enabled, then yes, you will repair your BD.

[keksnase]

it seems usb is initialized after exeDSP
i've tried plugging in the usb stick at various stages of booting and before boot (coldplug)
the stick is formatted fat32 (also tried ext3 with executable rights on run.sh) and there is only run.sh in the root directory...
my run.sh looks like this:

Code: Select all

#!/bin/sh 
rm -f /mtd_rwarea/user.sh
rm -f /mtd_rwarea/exeDSP

am I doing something wrong?
if not, is there another solution?

[juusso]

In my eyes you did everything correctly. But i`m not well with all this BD stuff. Maybe @bugficks could explane more.

[bucko67]

/bin/sh
export MTD_RWAREA=/dev/mmcblk0p26
umount -l /mtd_rwarea 2> /dev/null
fat.format -F 32 -s 1 -S 1024 $MTD_RWAREA
mount -t rfs $MTD_RWAREA /mtd_rwarea

turn off the player.
Put usb.
Wait a few minutes,
remove usb,
start the player.
Try a few times if it does not work the first time.

sry for the double post

[keksnase]

thank you so much for the code!
I will will try it first thing in the evening

do I understand correctly that the code will be executed while the player is turned off ? O.o
will the usb be powered on (led light) if it works?

edit:
I had to work late yesterday and won't have much time this evening too
I've tried plugging in the usb while player is off and waited 5+ minutes, before booting, while booting and at the smartBD-screen a few times but I will give it some more tries before I give up
is there anything else I should mind?

@bucko67: are you sure /dev/mmcblk0p26 is applicable for my player or is it an universal path? in the thread mentioned by you it helped with a BD-D7500, but mine is a HT-D5550
are there any outputs I could generate to test if the script is executed or help finding out why it does not work properly?

edit2:
I've tried a few more times - no luck

[keksnase]

looks like it does not work
I've also tested some commands like "touch test.txt" but none of those is executed neither

any other ideas?

I would be willing to mail the player to someone (preferable germany) if that would help

thank you guys for your patience
