[SOLVED] LN40B630 Help Bricked... in trouble with parents :(

[juusso]

Here is another way to mount rootfs over NFS. The rootfs is placed on network server and it will be mounted just after kernel load over tftp. There is a string about nfs in u-boot and i think it might work. We need place rootfs on server, export nfs shares and set correct env to root over NFS. Like rootfs=/dev/nfs
For more info search on the internet

Added:
I`m testing right now how to boot rootfs from dram. Idea is to upload rootfs and kernel to dram over tftp.
All what i need from you, flipper, post here your Output from "2. SHOW PARTITION"

Are you looking for dumps of ln40b630? Without dumps we aren`t able repair your TV. Please post announcement for other samygo users. Maybe someone will make and share his dumps.

Congratulations!
Isn` here any typos?:

Code: Select all

mkdir /mnt/nfsdir;
mount -t nfs -o rw,nolock,soft,async,udp 192.168.137.65:/root/rootfs /dtv/nfs

maybe:

Code: Select all

mkdir /dtv/nfs;
mount -t nfs -o rw,nolock,soft,async,udp 192.168.137.65:/root/rootfs /dtv/nfs

?

I found it. It is on /sbin/ directory. Could you post here the update.sh file? We need to compare it. Thank you. In basis of that file it is easy to roll back from februar firmware. Few tests are successful!

Ok now part 2 of the question.
Now that i got 1012.0 firmware, i just run the firmware through Samygo Firmware Patcher in linux and flash over USB?
But then what? How can i USE this hack? How do i run apps without a Content Library?

At first, is your tv CI or CI+?
If you flash hacked firmware with autostart enabled (samygo.sh), you can add samygo "games" with help of gdbtrick to run with tv start. You do not need to have content library for that.

So we found a new way to rollback firmware from me bricking my tv?

Actualy, we need to do more tests. Normaly february firmware does not accept earlier firmwares for upgrade. But runing this script with unxored exe.img and appdata.img on USB, we can flash firmware files directly. If we add right u-boot.bin, fnw.bin and Image, TV, after run this script tv becomes fully functional with working u-boot and TOP debug menu. We need just adapt code to create right firmware identification file (Version.x) on /mtd_rwarea/ and job is done.

About CI and CI+. Post here full TV model number from sticker on the side.

Please post here output of:

Code: Select all

cat /sbin/update.sh

Thank you!

OK, thanx!

I have got an idea after your success and i made a game for rollback. It supports not many models, but it works
I`ll add support B630 in next version too.
