everytime when the screen timeouts without the usb cable plugged in, the phone will restart. it happens after i recompiled the kernel or repacked it but not stock kernel. and if the usb cable is plugged in, it wont happen.
anyone know which part/module i need to look at? it should be the power management thing but i have no means to trace it since no log can be obtained
thx

Hi,
I want to update my ROM from a standard WM5 to WM5SE rev 5.0. Following instructions, I downgraded with the button ROM to let me CID unlock my G3 Jammin. The butotn ROM installed, but when it reset it would not boot and both the red and blue lights would flash together, the screen would flash on, and then it would shut off.
This pattern is repeated every couple of second and doesn't stop until I pull the USB cable out, after which it repeats once more then switches off. I can't turn the phone back on with the power button. From here I can get back into the locked cycle by powering on with the USB cable plugged in (back into reset cycle), or into windows with the mains power cable (see below).
I think this means that the problem is related to my USB cable being plugged in. When I put the mains power cable in, the PDA will boot into windows. Related to this is what I think may be the main culprit. In setting, Windows says the battery is on 0%!!! Even the mains power cable doesn't seem to ever charge it, so I think it must be a software problem related to the ROM. Inceidentally, I recall that I had to softreset near the end of Button ROM's install, perhaps this is part of the problem...
Now I can reinsert the USB cable only during the Windows boot process, which as mentioned has to be initiated with the mains power cord, ie. I swap over half way through. If I change from mains power to USB after Windows has fully booted then the phone resets and the above reseting cycle occurs again.
Once Windows is fully booted with the USB cable in everything is stable and Activesync detects the phone. The problem is that when I try to reinstall a stable ROM, the update software throws the following error: Error [220] mains battery power. So the software I believe is reading that the battery is less than 50% (ie. probabaly thinks there is 0 charge left) and I can't reinstall a new ROM!!
The other thing to note is that I can get into bootloader mode with the mains power cable, but as soon as I try to switch over to the USB cable, the phone resets and it again gets locked into the perpetual reset cycle.
Please help me!! Any ideas are appreciated.
Gavin.
Hi,
Found this: http://forum.xda-developers.com/showpost.php?p=1216580&postcount=23
Seems like a similar problem. He solved it by replacing the battery. Is it possbile to destroy a battery while flashing a ROM?

Wow 40 views, and not a single idea?
Well I think I'm going to invest in a cradle, so that I can have both mains power and a usb connection, hopefully I'll be able to reflash with this. Anyone have expereince with this method? What is a good cradle?
Hi, my Xperia X1 does not boot normally. I did not mess with the SPL or bootloader. I made a call, put it back in it's pouch, tried to make a call a few hours later and got the bootloader screen instead. All software and ROMs are stock standard and was never changed. I started by reading XDA forums. The phone will power up to bootloader screen when switched on. Serial is displayed. Plug in a USB cable to PC and this changes to USB. The PC makes its sound to indicate a USB device has been connected. It then says the device cannot be recognised and removes the usb icon from the taskbar. Activesync, mtty, SEUS or any other software will not recognise it. I have since put RA2 on a SD card and updated the ROM. This worked fine. There is no way I know of to HardSPL the phone as it cannot communicate with a PC. If you plug in the wall charger, car charger or USB cable to a PC, the phone will skip the bootloader screen and switch on. The phone cannot be charged while switched on. No charging symbol and the battery will still run down. Switch the phone off and it will however charge. Anybody seen this before? Any ideas how to fix it?
Thanks in advance
I have a major problem with my Tilt, when it is off and I plug it in, the phone will not charge and instead just boots up into Windows Mobile. While turned on, the phone will not charge; nothing happens when I plug in the USB cable.
The USB connector *looks* OK, no obviously bent pins or damage compared side by side to other HTC phones, but I'm not an expert with a microscope.
Is this a lost cause or are there things I can try to get the device to charge?
i'm not sure my observations will help you but i noticed the following behavior ONCE...i was too lazy to re-test and confirm my theory, but here goes:
1. if the phone was improperly shut down, the phone would turn on and start booting as soon as i would plug in my wall charger (NON HTC, its a generic Motorola charger). in my case, my device charges fine once the boot up has cleared the boot splash screen.
2. using the usb cable plugged into my pc, the phone would NOT turn on when i would plug in the usb cable. i MIGHT have shut down the phone properly prior to trying this but my memory isn't keeping up with me right now
i guess what i'm trying to say is that i THINK the device is built to turn on the moment a charging source is available, that is if it was improperly shut down.
Thanks for that tip...my Tilt is now plugged in via USB and will charge whether or not it is on or off. I still have to try it with the regular AC adapter, but at least it's not dead!
Edit: Everything is good to go Thx for the tip
I appear to be having wired issues related to the USB port as has been previously reported on the Galaxy S2.
When not plugged in to anything, it constantly says it is charging. It will not let me select between USB debugging mode as it says the cable is connected.
Despite it's belief that it is charging, when I actually plug it in to the mains to charge, it doesnt charge!!
If I power off the device, it shuts down correctly, however it will constantly switch between the grey battery icon, then a almost full green one, then off. It then wont allow me to turn on the device. Ive tried plugging it in to the mains (but I guess that as it wont charge this way, this is why it wont let me turn it on this way either) the only way I can boot it up is holding vol up, middle button and power together for 10 seconds or so. It then goes to CWM recover where I can reboot the device
If I plug in a jig, that allows me to connect a USB flash drive, it all seems to work OK. it no longer says it's charging, and i'm able to mount the drive.
The only way I can actually make it charge, is by plugging in to a PC.
Im very careful with my USB connectors, and I can only think that slight dampness may have entered as the phone has been with me in the bathroom during showers.
I dont want to send my phone in for repair, my first plan is to wait it out and hopefully any moisture dries out. Ive tried cleaning the inside of the USB port, but it makes no difference.
If I changed the USB port myself, a) is that a hard task, b) would it solve my issue?
I had a very similar problem with my note.
Solution was to take out the battery and leave the cover off, in a dry p;ace over night. It could definitely be related to dampness in your phone.
I have tried:
1. different charger/cord
2. hooking up to pc (doesn't recognize anything has been plugged in)
3. cleaning dust out of usb port
4. slightly moving the tab inside the usb port to encourage better connection
Weird things:
When I unplug the usb from the phone, it turns on the screen as if it knows something was unplugged.
When the phone is powered off, it charges very slowly
When I restart the phone, it goes through the app optimization (takes forever) as if I just flashed a new rom
