[S/W stuck rescue]Ultimate rescue guide topic

First of all, sorry for my bad english :D .
After i've spend alot of hours with flash after flash, fail after fail i found an easy way to rescue our Optimus 4x from dead.

You know what i mean when you get stucked with S/W screen, and you can't flash the device in any way.

So, what i've done?

1. I've disassemble the phone, till the motherboard.
2. I've disconnected all the connectors, and let only the USB connected.
3. I've hold battry manualy, while start KDZ flash, and BINGO!
4. Hold battery till the end of the flash, and you should get the LOVELY :


Before that, the flash stop at 17 seconds (10%) and i get Error 207 or 210.

I'll add images if someone is interested.
