After i updated my psp version to 5.50GEN D3, when i turn on my psp, nothing appear on the LCD screen. There is only green light. What should i do? Reply my asap thanks.

upgrading/downgrading or installing CFW in PSP is a risky business. the rule of thumb is to know if you have hackable or unhackable motherboard. if you had 5.03 chickhen before, then most likely you have a PSP-3000 or PSP-2000 v3 which has unhackable motherboard. you should have just installed 5.03 Gen-C or CFW Enabler 3.70, or upgraded the OFW to 6.20 and installed 6.20 TN-E or 6.20 PRO-B. 5.50 Gen-D3 is for hackable motherboards like PSP-1000 or early versions of PSP-2000. you have bricked your PSP!!!

for more details, check out sites like pspslimhacks.com, pspcustomfirmware.com or qj.net.

Hey there.
Before updating to 5.50 Gen-D3 (which is a higher version than yours), try knowing your PSP MoBo first. Why? Because, you may brick your PSP with the upgrade. Use PSPident to do that. Here's a link for that (MONSTER here!!!). Don't mind the monster, I just thought it's kinda nice doin' that. LOL
Now, do that PSPident in your PSP. If your MoBo appear to be TA088v3, DO NOT (never ever) upgrade to 5.50 Gen-D3 or you will have your PSP dead... If your MoBo is LOWER than TA088v3 (like, say, TA085v1 or v2) then go on with the 5.50 Gen-D3.
If upgrading doesn't solve your problem with playing homebrew, you may have downloaded a corrupted ISO or CSO file... Find a new torrent for that game again...
Happy playing...

Seems like a bad update or a bad flash. If either Pandora's Battery is the only thing that will help if you are out of warrenty.

Hi first i will say sorry for that. I will recommend that you see a certified technician to fix it up, there are a few things i guess are wrong with your psp... the system of psp are fragile and should be handled with care because i think one or more parts are broken and need replacement. Cheers

I guess you have custom firmware. If so, you can use a pandora battery to solve the problem. If you do not know how to make a pandora battery or if this doesn't work send me an email or add me on [email protected]. But pandora is most likely to be the solution. I had the same kinna problem but I was updating it thats the only difference. The green light is on and the screen was blank and then the light turned off. So I used a Pandora Battery and it fixed. :P

i hope it is due to problem in the lcd

Put psp to charge when turning on

I'll give you the quick story of what they did. They "bricked" the PSP. This is a term used by all PSP hackers. When you try to hack the system so you can play pirated games on the system, you will occasionally get an error that causes the system to be "bricked". They use the word "brick" because once it happens, the PSP becomes as fun as a brick. You really can't do much about it. Your best bet is to call Sony and see what they can do for you. If you know anyone else that knows what they're doing with PSPs, you could always ask them to fix it for you, but Sony would be the easiest. They won't do it for free, but they will fix it for you. 1-800-345-SONY

well if when you turn it on the power light turns green but the screen stays blank it means its bricked. this has nothing to do with the battery..
it means when you were updating the system software... the version... you turned off the psp or somehow stopped it.
you can fix this by sending it back to sony.
Or you can buy unbrocking hardware from places like ebay. all this is is a battery and memory stick that have had some software added to them and have been slightly changed. the is i think the best option because if thisu do it again u can just fix it

Did you download any firmware? What version of updates are you on? Its possible that your PSP is bricked. Which basically means that you hit a one out of one-hundred chance of you PSP being locked up and useless for that matter.
