[Problem][1.1.4]Cannot come out of sleep mode + iBooter NVRAM question
As the title states, I when the phone is put into sleep mode when it comes out of sleep mode it will either, freeze/restart. Occassionally it does come out of sleep mode ok but it seems erratic.
It started after I used one of those FM adapters to charge the phone. I have read the lengthy forum about this subject but wanted to try all software alternatives (not the band-aid) fix before resorting to replacing any hardware. My question is that has anyone resolved this issue? I have tried:
- Turning on airplane mode, restart, turn off airplane mode, restart
- Restoring (then Ziphone)
- Restoring (then Winpwn)
- Restarting phone while plugged into A/C and dock
- Deleted com.apple.SystemPowerProfileDefaults.plist but resulted in REALLY poor battery life
- Erased baseband and restored (update 07/16/2008)
- Attempted Dev Team Wifi fix (update 07/16/2008)
- Edited com.apple.SystemPowerProfileDefaults.plist (Possible Solution 07/16/2008)
What I have not tried is the Dev team wifi fix. I have done some reading and the result for the iBooter command "radio readnvram" is:
Type: 0x0004 Size: 0x0014 Purpose: Build Name (Looks ok)
Type: 0x0007 Size: 0x0004 Purpose: Not Available (Out of Place?)
Type: 0x0001 Size: 0x01f4 Purpose: WIFI Calibration Data (Looks ok)
Type: 0x0002 Size: 0x0006 Purpose: WIFI Hardware Address (Looks ok)
Type: 0x0003 Size: 0x0006 Purpose: BT Hardware Address (Looks ok)
Type: 0x0005 Size: 0x0006 Purpose: Ethernet Hardware Address (Looks ok)
I have manually changed the WIFI address with iBooter previously and all went well, I just changed the last letter/number. There is one line that looks out of place, but I am not sure if this output is what is normal. Can anyone offer any advice on what to do? Thanks in advance!
Update 07/16/2008: I have also noticed that the MAC address shown in the about page differs slightly from the WIFI hardware address listed in the iBooter output. Just the part that I changed using iBooter previously, the last 2 characters. Would this have anything to do with needing to use the Dev team wifi fix?
Update 07/16/2008: I have tried the Dev Team wifi fix, however it said there was nothing to fix, I used iBooter to change the Wifi mac address once again. Now the NVRAM read out from iBooter and the mac address shown in preferences matches up but still restarts when attempting to come out of sleep mode. Does anyone have any other suggestions?
Update 07/16/2008: After looking into the .plist editing and possible deletion of the com.apple.SystemPowerProfileDefaults.plist I decided not to delete the .plist to avoid really really terrible battery life. I have also seen other edits posted on this site for the com.apple.SystemPowerProfileDefaults.plist however those also resulted in poor battery life. So after a day of searching I found an edit for preventing poor signal life and attempted it and it looks like it is working so far. The usage timer actually shows standby and usage times are different so it is actually going into standby unlike deleting the plist.
The edit is to WinSCP to your phone and copy the com.apple.SystemPowerProfileDefaults.plist file to your computer and edit by changing the 'Dynamic Power Step' and 'Reduce Processor Speed' keys in each array from 1 to 0. If the key was already 0, I just left it as is. I will report back tommorrow after a full day of usage to compare this solution to the com.apple.SystemPowerProfileDefaults.plist deletion, having iMapIdle running all the time, and the com.apple.SystemPowerProfileDefaults.plist edit found on this site. Fingers crossed.

Reason: Update, possible solution
Update 07/21/2008: It seems like it can now come in and out of sleep mode properly after a full charge, however once battery life goes to ~70% artifacts start to appear on the screen, all apps crash and the phone resumes the behaviour of not being able to wake from sleep. Does anyone have any ideas?
