Can you get into the stock recovery?
Did you try removing the battery for a while and putting it back in? (while=1 hour to let the phone fully discharge)

HD2 Doesnt vibrate anymore..Even Htc sense

Guys i am facing a problem..i already searched the whole xda but i didnt find anything..my problem is that my htc cant vibrate anymore...even the htc sence and even when im typing to send a message...at the settings is already set to vibrate all the mods..but nothing works!!any solution please?
did you try a softreset or hardreset? also what rom are you using?
i did soft reset many times...i use stock rom 1,66....!
anyone please??
Do a hard reset. Yes, it'll wipe out all the data and apps but its worth a try. If your phone still don't vibrate, I guess you have a problem with the motor or something.
yeah thats it...
a problem can be caused by a installed program or something else...
after a hardreset, it has to work..if not, you've got a hardware defect.

Check on the back of the phone if your led flash is "pressed in". That could cause the vibrate to stop working.

Same problem here. Flash cover was pushed and stopping the vibration mechanism. openning the back cover and pushing the flash cover so that it flushes with the cover solved the problem. Openning the cover will void your warranty though.

Amazing!!! this worked for me too.
After all this time looking for a software fix...
Good ol' mechanical remedies if an army of vibrating HD2 take over the world, now we know how to stop em
son of a ....
I had the same problem, and found my LED flash to be pushed in after reading this thread.
I opened up the case to correct it. But after putting it back together not only does vibrate not work, but the volume keys, speakers (both earpiece and speakerphone), flash, notification led, and camera all don't work.
I obviously screwed something up, but I have no clue what it could have been. I was very careful. One thing I'll note is that when I pulled the case apart, the volume rocker went flying. When putting the phone back together I got it back into place so that I THOUGHT it should work (it was seated properly and felt "clicky" for up/down movements.
But no luck, all that I listed above is non functional, and what I'm left with is a glorified 3.5 in tablet
Any ideas??

HTC Sensation Bricked? Suddenly can't turn on anymore..

Hi guys,
I've run into some problems, I installed Android Revolution HD 6.5 two days ago. Everything worked like a charm, now I shutted down my phone to go in recovery, sadly enough my phone won't reboot, does not charge nor does it respond to my desperate pushes on the power button. Anyone experienced anything like this?
Worth mentioning also is that the battery was 80+% charged.. So it would seem strange to me that this would anything to do with eventual dead battery.
Just to be clear: hadn't installed anything, nothing less, nothing more.
If I could just get acces to bootloader through usb or anything like this.
I fear that there is someting seriously wrong here?
What are you guys thinking? Any possible solutions?
Hi,
The same thing more or less happened to me.
My phone went dead one night and wouldnt turn on, charge or connect with the PC. I had already arranged a repair with HTC for another issue and so I sent it off to them and a few days later I now have it back and it is working fine so far.
They replaced the mainboard and a few other bits and pieces all under warranty.
I hope you get your phone fixed and sorted asap.

Did you root it or anything like that? It really seems like an hardware issue.. Thanks for your reply also btw.

Hi,
Is there any chance the battery pins could be damaged or bent?
Is there any way for you to get hold of another battery(from a shop or friend) and try that?
I will test the battery in the laboratory tomorrow.. I've read you should get a minimum of 3.6V or something like that? Curious to see what has caused this problem. Do you think htc would see I flashed a custom rom on it if I send it to repair?

Hi,
That is why i suggest a different battery.
If they can switch it on,they will see the s-off.
If they cannot,it does not matter.

They don't use a JTAG unit or anything like that to see what has went wrong than I presume? Well, first thing I'll do is test it right away at the laboratory. I will post the result in the evening.

My sensation was rooted and had a custom ROM on, but I was preparing to send the phone back in when it got bricked. I had managed to install stock rom and do S-on but the phone had an unlocked bootloader using HTC dev website, so I was worried they wouldnt do the repair.
As it happens they did all the work under warranty and didnt say/ mention having unlocked bootloader. It has come back locked though.
Was anybody able to find a fix for this?
My sensation 4g has basically the same problem. After rooting and installing ICS it worked fine for a few days then it ceased booting or responding to a charger (no LED response). I was able to turn on the phone again by letting it sit for a while but no luck lately. I'm wondering if my phone is bricked?
When I press the power button the screen stays black with lights on (no LED).
I can't get into bootloader and the phone is not detected by ADB, I tried the unbricking project thread by Dexter, however my phone is not detected by linux. On windows, i did get it to detect as qhsusb_dload.
Any thoughts would be helpful!
Thanks

If your getting QHSUSB DLOAD I'm so sorry to tell you as I believe your device is HARD BRICKED. You can try jtag. If you search there are several companies who will jtag. I'm wishing you the best and I'm sorry about your device.

I had to return my HTC Sensation to the repair center. Apparently the motherboard just fried. I got a new motherboard and just S-OFFed the phone again. Very weird problem though. As has been said in this post earlier, if they can't turn on the device they won't see it is S-OFFed and your warranty will apply.

Sometimes turning the screen off, waiting three seconds, and turning the screen on again will fix unresponsiveness. If the screen will not take ANY user input, then try a reboot. I don't know what you mean by "it acts like someone is touching stuff"?

What do u mean.. Should i turn off the phone or ?? And i mean it acts like im touching apps and stuff when im not even touching the phone so it just opens random apps
backup up your phone with cwm, then factory reset or odin to stock so you start fresh and if you are still having the screen randomly pressed its probably hardware issue.

If u r already using stock firmware then better go to Samsung service center.
If ur on some custom rom then 1st try stock rom & check whether our works or not.
Stock firmware= stock rom.
Good luck!

If you're screen stopped working after dropping it, it is most likely damaged. Dropping it will not cause any rom to malfunction and stop touch from working. It may be a loose connection, or if you got the device used from somewhere, the screen may have once been replaced and the replacement may not be as good as the original (which by no means was perfect either).
It happened to me. Open your opo, disconnect and then reconnect the screen.
