Hi,
I don't know exactly what is wrong there.
Using Firmware Patcher is not intended to lead such a failure.
Do you sure about your firmware model?

I am suspecting about if your firmware model is different than T-CHL7DEUC...
Depending our compatibility table, you needed to use T-CHL7DAUC for LA model B650's.
So you might not recover you TV with SM resetting.

If I were you, try to setup proper ExLink connection (don't know what 's wrong with your connection) and boot via External USB Flash.
Than you could use "Alternative Firmware" at your TV to recover it.

I completely agree with you. Just as desperate step when nothing more left to advise... :?
Sure, if here were connection to TV, it would be restored already...

Yes, joining tx and rx works well and it indicates - cable is OK.
I wondering why here is no debug button on mainboard and why we do not get any signal from TV - rs232 was set to debug before flashing patched firmware.

This is the second TV i ever heard about, witch falls because of patcher. But other one had TDM access and shell over it...

Sure, LA models should have T-CHL7DAUC firmware on board. But now it is not important - we can`t enter neither u-boot promt nor debug console.

calvinyeoh,

Did you try enter to u-boot? Press and hold ~ on putty terminal and power on TV. Blind, just for a try.

Good news.
Check what firmware version is in service menu- very first screen. is it t-chl7deuc 3001 ?

If yes and you still want use.SamyGO, make dumps of your TV with SamyGO dump maker lite and give me dump files and log files you get for inspecting. If everything ok, you could restore your missing partitions to get access over exlink (you should be 100% sure) and then without any scare install patched firmware again.

So i think you need:
1. Make dumps (using Dump maker lite)
2. Restore kernel (after i inspect dumps) to have access to console over exlink (using FFB)
3. Check if you get TOP debug menu and u-boot working
4. Download clean firmware from samsung
5. Patch it once with 0.24 firmware patcher by enabling advanced startup (a)
(you could use already prepatched firmware as well)
6. Upgrade TV with patched firmware
7. Enjoy!

According this plan, if you get bricked TV, BUT steps 1-3 are done, you restore it in 5 min...

It is up to you what do you do now ;)

check SM settings to have "debug" and "watchdog off"
Try access u-boot menu
Try access TOP debug menu

It seems your fw is unrestricted one.
