Not long ago I bought a quite beaten HD2, TMoUS. Glass adhesive gone loose, screen dirty from the inside, phone had been opened and badly fixed already. Guess what? No thermal pad over the EMI shields. Here's what I found: you can remove the board from the phone, place a thermal pad of the same greenish-blue kind usually found between the HD2's case and board (pad can be found inside dead laptops) between the CPU and metal shield. Then place another pad between shield and front frame. Put board back in. Place more pads between board and back case. Close it, you're done :grin:

Just as a side note: my phone, even though badly assembled, wasn't overheating. I also found that this works for Nexus One and Desire, those two also put out a lot of heat, and both share the same board.

Phone #2: Milestone B (A953 in A853 shell), stock Moto crap (broken volume buttons, no flashing )
Tab #1: Nexus 7, 2012, WiFi+16GB
Tab #2: Asus EeePad Transformer TF101, stock ICS (broken USB cable, need new one :P )

Test phones: Several

Others: Over 50 WinMo/android/Symbian/other devices in this short life of mine

Remove the CPU cooler, should find these slippery, rubbery pads on top of some components. Usually found in HP laptops, lots of them which had AMD CPUs failed easily, and they have this stuff inside. Can be found cheaply. Don't use thermal paste inside the phone, as it gets messy. The silver one is better, but still, inappropriate for use in a phone. I see you're using a Nexus One. You want to apply thermal pads between the QSD8250 chip on the rear side of the board (under metal shield, careful, shields held by copper tape) and the metal shield covering the QSD8250. Put a pad between the metal shield and the phone's display. Careful there, a pad too thick will force the display and break it. Last one, put a pad between the MicroSD slot and the aluminum frame of the phone. There already is a small pad there. Remove it.

Man, great info on here!

I'm especially curious about your mention to use the oven. It's actually not too uncommon to place dead computer components in the over for a bit to fix broken solder points by reflowing them.

Curious to see how this turns out for you.

Smile Ideos S7 105 baked and works

Yesterday I baked in the kitchen oven the motherboard of my Huawei Ideos S7 105, and now almost every thing is working. Reboots and hangs finished!!!!!!
I've read the entire thread and recognice the problems I was suffering since a year ago.
So, better baked than bricked
But the oven fixed the problem.
Only colateral damage in one speaker, maybe due to a incorrect rebuild.
Its working fine with GPS, Google maps and every thing.
Before cooking it was only able to do hard work inside the freezer, for example load the last room.
Difficult unmounting the motherboard, specially screen connector, same as remounting.
Work in the oven was 10 min at 100 C and 5 min at 250 C, then natural cooling, half hour.
Rom ideos. s7 froyo from joenilan
thanks to all
