My S2 won't turn on - Galaxy S II Q&A, Help & Troubleshooting

First of all, sorry but my English is pretty bad.
I have a S2 that I want to use it just occasionally (as businesses phone). It charged perfectly but sometimes it shows this 'error'

I've tried installing CM and Gapps but i can't from stock recovery, so I also tried to install TWRP from Odin but i get another error.
You guys know any solution or is completely dead?

Do a Google search for:
"USB jig for Samsung"
Or a search for:
"300k resistor method Samsung"
You'll find information for a couple of different tricks to force-boot your device into download mode and then you can flash your stock firmware using Odin.
If it is at all possible for you to revive the device, this should do it.
If it doesn't, then it can only be repaired by:
1) replacing the motherboard
2) a JTAG service(or buy the expensive JTAG hardware for yourself and learn how to use it). The service is probably still around $50 but I'm not sure.
3) Pay for an Octo box or a Riff box service(or similar hardware interface equipment)
Or buy the Octo box/ Riff box or other interface for yourself and learn to use it.
There is also, possibly, a trick that involves a somewhat complicated method of booting a stock debrick.img that has been burned onto an external sdcard that has been formatted as a "bootable" drive and then using the booted OS to repair the partitions on the device, then after everything is restored and booting properly without the external sdcard, you return the external sdcard to normal format as storage instead of as a bootable drive. You can probably find a copy of debrick.img(sometimes labeled as debrick.bin) for S2 or maybe you can get someone else here with a S2 to pull a debrick.img(.bin) from their device using terminal emulator or adb shell. If your device does not at least vibrate or light up the capacitive hardkeys when you try to power on the device, this method of booting from external sdcard will not work on your device but a JTAG service will probably do the job, however, there is no guarantee that the service will work.
Also, I can't see what the second photo that you posted is. Can you repost it correctly so that I can view it?
