Made mistake in user.sh patched BD-D7500B wont boot

[alessio71]

I've made a mistake in the user.sh script, just before the

Code: Select all

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

command
the BS starts, dispaly the logo and stays there, no root access

Is there any chance to get it back?
Thank you

Alex

Oh damn, this is really bad. You have to delete user.sh... Same as sbav1 suggested for Prairie...

Looks like what you need is mtd_rwarea partition clean-up/reformat - but I don't have any useful ideas how to do it by any simple hardware hack[s].
In theory (just maybe): if you'll be somehow able to disrupt OneNAND <-> SoC communication in the VERY precise moment (to prevent initial /mtd_rwarea mounting in startup script), it may then get erased/reformated.

No serial access? If you have the USB hotplug patch you can remove this file using run.sh on USB stick

[juusso]

Oh yes, all Fir* patched firmwares have usbhotplug patch enabled. Take fat formatted usb and script (made under linux or if on windows, then with notepad++ or other robust editor, save ANSI encoding)

Code: Select all

#!/bin/sh
rm -rf /mtd_rwarea/user.sh
insmod /mtd_exe/fpi.ko
/etc/Scripts/MicomCtrl 143

While BD is powered on, attach USB and wait

Nothing to do, the USB disk's LED flashes at same with the main circle LED in front of the BD and nothing happens
Any other option? Some kind of factory reset?!

Thanks for your effort,
Alex

[juusso]

how your latest user.sh looks like? what modifictions did you done?

I don't know if it'll work, but try this:
Create that script with Notepad++, ANSI encoding

Code: Select all

#!/bin/sh
rm -rf /mtd_rwarea/user.sh
insmod /mtd_exe/fpi.ko
/etc/Scripts/MicomCtrl 143

Save it as "rc.sysinit"

Create a folder in your USB disk named "SamyGO", then inside it create a subfolder named "etc", and copy rc.sysinit script in there (so it should be <USB>/SamyGO/etc/rc.sysinit).
Plug it and restart your player.

I was trying to start a newer version of exeDSP, I tried what stated in the wiki: http://wiki.samygo.tv/index.php5/ExeDSP_modifications
and didn't work, the newer exeDSP didn't start; then found this user.sh in this post: viewtopic.php?f=57&t=5275&p=38499&hilit ... .sh#p38499
and tried it:

Code: Select all

#!/bin/sh

Plug it and restart your player.

Nothing, if I start my BD with USB in it, the USB key's LED doesn't even turns on, I get some kind of response (USB key's LEDflashnig on/off) when I plug it later, after abot 30 sec. from boot.
What i did: I've connected my USB key to a linux machine, formatted in vfat, created user.sh in the root as suggested before but this did'nt work, created the SamyGO/etc folder and rc.sysinit in it, even launched the chmod 777 on both sh files but nothing, when i start my BD with the USB key in it nothing changes, I get this Samsung logo and nothing more, the same without USB key.

Thank you,
Alex

Damn, you should get your own rc.local and rename it to user.sh, then add some commands, not just get someone else's user.sh..
I don't really know what you can do now..
