Manual firmware downgrade, blocked SamyGO by Samsung

[lukeki]

Hi

Dear comunity, I need yours help with understanding all the knowledge from Wiki.

My TV is UE32ES5500
I had before firmware T-MST10PDEUC_1032.0 on my TV hacked with SamyGO widget, installed via USB (InstallSamyGO).
I configured everyting to fit my need (Samba Server, virtual USB etc.) and everything was fine till SmartHub update forced by Samusung couple days ago. SamyGO stopped working, I lost FTP, telnet access and other features like Virtual USB, Samba Server.

First I tried to reinstall SamyGO same way like it was installed, without any luck. Then I done factory restart of SmartHUB and then of everythig else in Service Menu. Then I tried to install SamyGO, once again without any luck. Widget is always installed and after run it in SmartHUB there is notification that everything is fine, but I don't have telnet and FTP access.

So, I tried factory restart and SmartHUB reset couple more times without and success.
Then I done firmware upgrade to T-MST10PDEUC_2000.2, restarted SmartHUB and installed SamyGO widget. Also this time everything installed same way without telnet and FTP access.

Then I rooted TV with Wiki's "Rooting the ES-series" manual. And this is working, I have shell and FTP access. But disadvantage of this solution is that I cannot use features like Virtual USB, Samba and needs to run hack every time.

I tried to find out why SamyGO widget is not working, I tried to run it manually from shell (.sh scripts) and check by FTP what is happening on file system.
I find out that there is no permission to create any file or mount anything in "/mnt", tried to change permissions with chmod but this was impossible to do.
Then I tried to use "/tmp" instead of "/mnt" for SamyGO, I can create files there, so I changed .sh scripts to use new path, but this still is not running SamyGO. Maybe path is transcoded somewehere else...?

I has trying also downgrade firmware usung "DNS hack" from Wiki's.
But when I configure this DNS, TV says that there is no internet connection and I get error 800 when I try to upgrade firmware online.

Can you advice me what else can I do?

Maybe I can downgrade firmware via USB. Patching firmware T-MST10PDEUC_1029.0 with this manual "http://wiki.samygo.tv/index.php5/Extrac ... s_firmware". But I'm not sure if this operation will not brick my TV. I read all manuals on Wiki, forum and I'm very confusted now about this patching.

[zoelechat]

No downgrade possible at all on ES/MST.

What you can try:
-gain FTP access using wiki method
-verify that you have SamyGo folder in /mtd_rwcommon/widgets/user, else reinstall SamyGo as usual or create folder and unzip it SamyGo widget found here: viewtopic.php?f=53&t=5797 (then launch widget once)
-unzip/replace attached files in /mtd_rwcommon/moip/engines/Skype (if you can't find folder, first uninstall/reinstall Skype and launch it once, may be needed even if you find folder )

libSkype.zip

-reboot TV

edit: Be aware that nobody(?) here has experienced latest 2000.2 firmware so I can't confirm SamyGo still works with it.

OK, I've done all the steps very carefully couple of times, but without luck.
Widget is installed and Skype autostart is trying to run it on startup, but image 128mb.xfs is not mounting in /mnt or even in /tmp when I'm changing script run.sh.

Can you advice how can I try to debug and find where exacly is the problem with script?
This is basicly Linux, so when I have root shell access maybe I can run some external libraries and get logs in which line of run.sh I have failure.

Also what do thing about patching firmware T-MST10PDEUC_2000.2 and trying to upgrade from USB? (http://wiki.samygo.tv/index.php5/Extrac ... s_firmware)

[lukeki]

I found where the problem is.
Actually there is couple of problems after SmartHub and firmware update.

1. Functions like: eval("FilePlugin.Copy(\"/proc/self/cmdline\", \"$(sh /dtv/usb/sda1/run.sh)/dtv/usb/sda1/cmdline\")");
In widget not working anymore, I can use "FilePlugin.Copy" only for copying files.

2. Path /tmp/loopnone is nonexec now

I'm using now root solution from wiki, but I've modified run.sh script like that:

Code: Select all

#!/bin/sh

cd /tmp
mkdir /tmp/bin
cp /dtv/usb/sda1/bin/* /tmp/bin/
chmod 777 /tmp/bin/*
/tmp/bin/busybox --install -s /tmp/bin
sync
export PATH=/tmp/bin:$PATH
export LD_LIBRARY_PATH=/tmp/bin:$LD_LIBRARY_PATH
sync
/tmp/bin/busybox tcpsvd -vE 0.0.0.0 21 /tmp/bin/busybox ftpd -w / &
/tmp/bin/remshd &
sync
mknod /tmp/tmpfs b 7 9
losetup /tmp/tmpfs /dtv/usb/sda1/128mb.xfs
mount -o sync,exec /tmp/tmpfs /mnt
sleep 10
bin/sh /tmp/bin/start.sh &
/mtd_down/emps/empWebBrowserDRI/bin/BrowserLauncher

In start.sh code looks like that:

Code: Select all

#!/bin/sh

chmod 777 /mnt/rcSGO
sh /mnt/rcSGO

So, basicly I've changed /tmp/loopnone to /tmp/tmpfs - this one is still executable.
And after running root solution I'm running SamyGO Extensions Pack.

I have all the features of SamyGO now.

But the last problem I have is that I cannot get autostart for this script and need to run manually Widget and then Webbrowser everytime after reboot of TV.

What I can do is to call script with /mtd_rwarea/start.sh to get autostart, but this is too risky I think.
Can you please advice how can I restore TV later if I'll make some mistake with /mtd_rwarea/start.sh?

[juusso]

dont touch start.sh, here is no way to repair tv if your start.sh is not correctly made or fails to start.

please give the content of /mtd_exe/rc.local

Here is content of my /mtd_exe/rc.local file:

I have the same issue after media hub was auto updated on UE40ES6100

[yepp]

got the same /mtd_exe/rc.local

successfully made auto boot with /mtd_rwarea/start.sh
