I purchased NEW bricked Desire (Bravo) from a guy that got it from Belgium as a gift, for very cheap money. Guy turned it on for the first time here in Serbia and the phone worked 3-4 days, and then died. never rooted, everything stock.
I took the phone, and pushed Power button - and it turned on (Oh, how I regret I didnt use "volume down" at that point) and it got stuck at green HTC.
I took out the battery and after that - not once did it turned on, or LED turned on when charging or anything. No boot.
then I read all the threads I could find, and the conclusion is that it's bricked and it needs JTAG, and nothing else will help. But, after some time without battery in the phone, I putt it in, and the phone vibrated 7 times and not even a flicker from the screen.
I actually opened the device (it has Belgium warranty but with serbian custom regulations, sending it and receiving it back is more expensive than brand new Desire) and checked everything - good solder, battery good (it has voltage), everything is in place.
My question is, as I dont understand software part of the phone - HOW does it even vibrate 7 times, and if it's bricked - WHAT is giving the phone instructions to do so ... ? If it is able to vibrate in a pre-defined manner, then something is working inside the device. And that something acts random (didnt turn on with the guy, turned on once with me, now wont turn on again) so Im asking - what part of the SoC is actually working to enable that 7 vibrates, and why is it acting random .. ?
note: HTC NEVER gave ANY explanation on those 7 vibrations. phone-repair forums from Russia dont know the story behind that also.
I will eventually take it to a service shop where JTAG would be preformed, but I would so much like if there was another solution ... If it turned on once, how do I make it turn on again ... (so I could use ADB to sort out everything)
anyone with advanced knowledge on this one .. ?
