Nokia n8 hang on logo....please Help

[Arunsf]

Hai Friends..

Here is my problem.

I installed Figs-4 CFW on my nokia N8 Using phoenix.Later i tried restore it to Belle Refresh (I am not a technician and don't have proper knowledge in mobile flashing.I am doing all things after watching tutorial videos ).After flashing my phone gets stuck on Nokia logo screen.I tried other CFWs but the same problem existed.Then i flashed with figs4 for once again. Wow it's worked.I could use it perfectly as before.Then flashed with figs3.1 That's also worked.((( FlaShIng iS FuN )) ......... I have little knowledge in Computer softwares.In that base i came into a conclusion that "Figs cfw" is injected some reg keys into my phone.So i should remove it first for use any other firmware......... ( CrAZY tHoUgHts )

After searching and watching tutorials, downloaded "Nokia Infinity Best BB5 service tool"...... ( Real Problem Starts .

i "Erased Rpl" "Erased Flash". Then i flashed with "Belle refresh fw" and other CFWs But the issue still alive (phone gets stuck on Nokia logo screen ).I wanted to stop this crazy game with my phone and made a decision that let my N8 live with figs4 cfw forever.I flashed with figs4....Now The issue affected to the figs cfws also figs4,3.1...Phone gets stuck on figs logo screen(colorful nokia screen)..

I Gave my phone to a shop.Technician notified me that there is some Errors and contact them after 4 days.
I hoped that they will give back my phone in working condition.In that hope i uninstalled Nokia Infinity Best BB5 service tool and "Deleted All Backup Files"

I Love My N8.I cant miss it.Technician returned back the phone as i given.They told me that they couldn't repair the issue .So please Help me to bring my nokia n8 Alive.

Again i installed bb5 service tool and made Read rpl test.Here is the log and there is an error at PAPUBkeys
