6210 checksum errors

[Wireframe]

Hello. I have been lurking for some time, but now I find I require some help. I ahve a nokia 6210. Recently it started resetting randomly, about every 20-30 seconds. Then it would sometimes say "contact service" and need the battery removed. Before I managed to corrupt (by overwriting) my original .fla, it said there was a checksum error. Does anyone have any advice. I could really do with a new .fla file. I use rollis v4.78 build006. Does anyone have an original (or just plain working) 6210 original .fla file I can download? It should be about 4 meg, it seems. Before I managed to corrupt (by overwriting) my original .fla, it said there was a checksum error.

Also, does anyone have any more advice? I have tried the "contact service" guide, but EEprom tool won't read from my phone (says com port 3 is busy)

I really appreciate any help you may be able to give.
Thanks

OK, I fixed this, I got a flash pack from a good nokia. However, the phone still randomly resets a lot. Any Ideas?

Thankyou for your help Chunkhead. Your guides have helped me a lot in the past. However, thistime your soultion didn't fix the problem. The phone STILL randomly restens even after following your guide. Any other ideas? It seems more stable, but still sometimes resets, and sometimes displays "contact service".

Get a clean flash file from here: www.handy-flashpage.tk and then use my "Contact Service" guide in conjunction with the Rolis And knok guides! You just have bad software!!!
