*** A question about 8210 for professionals ! ***

Well, can anybody knows what is problem in following:
My friend gave me his 8210 to repair (Contact Service). I have read phone, and its original version is 5.28, ROM6. And, I said to myself "No problem!" But... I flashed it with his orig. version again with Rollis, and the thing is same. Although I did update FAID and Repair IMEI, phone is in "Contact Service". I used Jordik Tool and saw that original IMEI is 6565656565.... and his IMEI now is ????????????????. I changed IMEI in the same prog., and again update FAID and repair EEPROM, and situation is little different. Phone is now OK, and Eeprom Tools tests is OK. But, when I turn on phone, immediatelly after finding network, phone turns off itself !!! I tred other sw versions (only ROM6), and all situation is same.
Ha? Problem?............or not?
Is there hardware fault or it is all sw? What to do?

Would be safe to say thats a hardware problem, I had a 8210 like this, flashed alsorts of software to it, but after about a days use of the phone it would restart and go in to C/S again. Never did fix it broke it down for spares.

When CS appears try to run test in Eeprom tools or Wintesla first and then do whateaver is necessary. And if it is the HW, then try to reheat or reball CCONT or COBBA. ;)

How to reheat or reball CCONT and COBBA ?? Which is procedure for that?:confused:

You have to have a hot air station, soldering pasta, reballing kit and experience ... ;) ... but if you have no idea what is this all about just let the profesionals do it for you like some repair shops etc. ...

Yeah,

I found the problem! :D I make stronger pressure in the area above keys 1, 2, and 3, and the phone stays on after finding network!;) It seems to be factory fault by Nokia in this models. Thanks to all who took a part in this forum, especially dbrus12 from Croatia!

Well that's probably broken soldering balls under CCONT or COBBA, dude.

Well, I have just got the tip: "Sell your phone while it is still working, as soon as possible!" Hm......

Yeah ... good one ... :D
