Does the light go green first then go orange and finally turn off?
If so you will have a brick and have to do the following.
1. Connecting SE0 to TRISTATE (without soldering; and not to the SE0 point)
2.The only (and must have) purpose of this connection is to keep your PS3 power up the motherboard and E3 flasher without shutting down. This allows the E3 flasher to flash a working copy of the firmware into its storage in its memory board (commonly known as the NOR processor).
3. It works by connecting the TRISTATE to a 3.3 voltage. So happen that the SE0 of the E3 board is 3.3 voltage, hence the official instruction is to solder these two points together. There are many issues with this soldering – the distance is far too long between these points, the connection pad on the E3 flasher is way too small, in particular it makes disassembling the PS3 extremely difficult once soldered. I do not recommend soldering these points.
4. Instead you can try connecting the TRISTATE point to other 3.3 voltage points on your PS3 board (there are plenty of them). These points are different depending on the different version of PS3 you have. At the bottom of this site

5. Instead of soldering, try use any wire/cable and sticky tape to connect these two points. Remember – it’s the objective that matters. Don’t hang on to the soldering comment from the official site.

This would be the only way to fix it if it is bricked and the PS3 is not staying on mainly because this draws power from the motherboard instead of the HDD slot and as such you will be able to get back up and running.
Just make sure that you have a valid dump first by double checking the dump and if the console is banned then you can ask people to look over the dump for you. DO NOT DO THIS IF IT IS NOT BANNED OTHERWISE THE CONSOLE ID WILL PROBABLY BE STOLEN AND SOLD.
