From some days ago, my S200 started restarting itself sometimes (like once or twice a day).
I thought it was something to do with the ROM but 3 days ago I woke up and the phone was completely turned off. I tried powering it on with the Power On button but nothing happened.. Tried Soft reseting and hard reseting and nothing.. Removed the battery for 10 minutes and then it powered on but the screen started flickering (horizontally, 1 pixel).
Then I saw at BatteryStatus that the CPU speed was jumping from 195 MHz to 91 and 52, randomly (195, 52, 91, 52, 195, 91...).
I searched the net and did found almost nothing, just a forum where they say that 195 Mhz is the normal mode, 91 Mhz big sleep mode and 52 Mhz deep sleep mode.
Even if I overclock it with BatteryStatus, it doesn't maintain the speed, and slows down to 195/91/52.. (Even with speeds below 195 MHz it doesn't fix).
(Sometimes it doesn't enter the Standby mode, it only turns off the screen and the battery discharges in a few hours)
One day I plugged it in at night and in the next morning the phone was charged (green light always on) but I pressed the button to power on the screen, and nothing.. Removed the power cord and the green light kept on. Reinserted the battery and tried to turn it on, and nothing.. Resets did nothing, it was completely dead. Took the battery off and after one hour I put it back, and it powered on (with screen flickering and that CPU changes..).
I think the problem is on the CPU.. I reflashed it with other ROM's just to be sure it wasn't from the ROM (although I used that ROM's without any problems before).
One more thing I remembered, the WiFi isn't working (from some days ago, before that CPU changes...). It doesn't turn on.
Sometimes, when connected to Activesync via USB, it keeps the speed (195 MHz) and the screen stops flickering.
Sometimes, it loses network from mobile operator and I have to turn the phone (not the pda) off and on, or soft reset, and sometimes it freezes and I have to soft reset or re-insert the battery...
Any help appreciated... Thanks in advance
