Himilaya "Find Window Fail" resets after splash sc - MDA II, XDA II, 2060 General

Hi all,
Hoping you can help me out with the himilaya i've got. I am currently using an xda mini s from uk but am working in kolkata at the moment and have been asked to fix a himilaya for a friend. the details of rom and radio version are below. the splash appears as usual on booting and loads for approx 4 seconds, then displays a small box with heading "Find Window Fail" with an OK button on the same title bar, and an empty box below. After displaying this for less than a second it just restarts and does repeats this process until the cows come home.
I've read through a lot of the posts here and have tried searching but can't find anyone else who's had the same problem.
Should I try reflashing (have never done this before) or will it even be possible?
Any help will be much appreciated. Fred
ROM = 1.03.00 USA
Radio= 1.05.12

I've now got the problem that I cannot even load bootloader, i've tried all the suggestions in other posts of leaving the battery out for an hour or more and then trying power, reset and navigation button all at the same time, it is literally dead. not sure how this happened, it was entering bootloader before and i left it overnight, now is totally unresponsive. tried recharging main battery seperately, no luck, when its in the cradle the red light comes on with no battery in it. have also tried formatting buttons (record camera and reset) but still nothing.
is there anything i can do??

still no luck, would taking it apart and taking the backup battery out and back in help?
any advice please

I have the same problem for 4 weeks now, still no luck in entering b/l mode.
Pls advise if you succeed, ok?
10x,

XDA2 not playing ball.

Hi all,
Did a search on this, but hoping to prompt some new info on this.
While using my XDA2, running the latest WM5 from TofC via Buzzdev.net, with Tomtom it froze. Nothing too unusual with that, but this time the usual remedy of soft resetting it left it stuck at the splash screen. Same thing happend after removing the battery for a short while. I left the battery in, with it stuck at the splash screen, and the device became quite warm (as though it was working overtime).
Afterwards, I tried removig the battery again and then hard resetting. A couple of times, I have go it to boot MOSTLY, but the backlight will not come on (yep, I have checked the settings) and there are no sounds. Also, when it goes into stand-by, it wouldn't switch back on again.
I have since tried reflashing it with the WM5 rom (stuck at splash screen again), and flashing with the official O2 rom / radio (still stuck at splash screen).
From what I have read, it might be a battery problem, but I have tried charging the battery fully (in the cradle, not in the PDA) and nothing.
The battery I am using is a replcement from Ebay, the original is with a friend so not available for another few days.
Any fresh ideas most welcome!
Well, didn't expect too many replies :roll:
But academic anyway, because the 'brick' is fixed!!! After leaving the battery out overnight (not for the first time, I hasten to add) the XDA2 has decided to boot
It now has an XDA2s version on WM2003 (just thought I'd try it). Pretty sure though the issue wasn't ROM related, because it had been freezing at the same point with this new ROM.
So, anyone with the same problem on their device should not give up hope!

Please Help-Wizard Won't Boot After Flashing

I have a g4 8125 and tried to flash black diamond 2.0 using shelltool. I followed all the instructions, but I may have messed something up. I installed the enablerapi and certspcs files on my phone, but i realized later that i did this after turning off my radio. After flashing I made a hard reset, and now it just comes to the cingular splash screen and shows my ipl, spl, gsm and os (which it says is 6.0.0.0) and doesn't load anything. Anyone have any ideas? It won't connect to activesync either.
edit: sorry for my ignorance, thanks for the help though!
Please refrain from posting WITHOUT using the search bar. This question has been answered more than a million times.
For starters, hold down the camera + power button whil poking at the reset button
Hello there.
This is my first post, and I hopefully pray that I don´t get a "Please Do a search" kind of answer as I have been doing a hard search through the forum but haven´t found what I´m looking for. Probably I´m just using the wrong search terms but english is not my native language so I´m not sure how to look up for this issue.
First, I unlocked the sim of my device by sending it to a third party. Afther that, the phone came with a Wizard-Love OS installed, and finally I got excited and started to mess around with the Shelltool to get the device upgraded to WM6. (It´s a G4 by the way).
First I successfully upgraded to wm6 wee htc wizard v5.2.660, but then I found that the keyboard mapping was all wrong with the shown special characters (they weren´t where they were supposed to be at all), so i tried messing up with the registry trying to select a local language for spanish with no success at all....
Also I was having some issues trying to connect to internet via wi-fi even when I did get connected to the network, but did not test it hard enough.
Then I went farther trying to "shelltool" a Black Diamond 2.0 Touch rom, but then everything became a real mess... The Shelltool said that it was finish only like 4 to 5 minutes after starting so I disconected and Hard Reseted the unit. Don´t remember if I disabled the radio before flashing it, nor if I had the sd card installed on the device at the flashing momment, but definetly i had reinstalled the cert_spcs and EnableRapi cabs prior to this seccond attempt.
After the hard reset, it started but freezed on the first screen showing the ipl, spl, gsm and os (which it says is 6.0.0.0). Then I hard reset like two more times, with no luck. Then I entered on the bootloader mode, but after trying that for a while the phone stopped responding. It did not turn off, so I removed the battery. Then when I put the battery back the unit did not turn on at all. Even it did not show the charging red light when I connected it to the usb nor the wall ac adapter. I was devastated... I leaved the unit with the battery out all the night and the next day I reinstalled the battery to see that the device did turn on and did charge, but still it was locked on the splash window.
I tryed to reflash the unit using the bootloader under windows xp, after killing the activesync connection and using the wizard_Love_2.26.10.2_WEE_Novii_CF2 rom. The unit showed a progress bar so the pc and after 10-12 minutes it was done. I Hard reseted the unit but then it always started on the bootloader screen as if I was pressing the camera button.
Hard reseted, soft reseted, battery out and in, no luck. Then it went dead again. It did not turn on at all and no charging light. Once again i leaved the unit all day without battery and send it to the friend that had unlocked the sim for me. He just called me and told me that the unit was now up and running again with wizard_love rom. I´m really not sure how he did it. Probably i did something with the sd inserted when it was supposed to be out. I did flashed the wizard love on bootloader with the sd inserted but i´m not sure if that could have make the mess.
I would like to know if anyone have had this kind of lock up and how to deal with it (how much time to leave the battery out, etc). Also I will love to know how did my friend (he wont tell me as is it´s bussines and he charges for it) finally restarted my unit flashing wizard_love again, as I´m still too curious to not try to flash my unit again and probably be on the same mess once again.
Thanks in advance.
That's a lovely 1st post. If every one is to be like that.. it would be just to nice to help others.
Anyway, this may not sound logical, but I get problems with Shelltools when I do not have the official ROM flashed before another flash. What I would suggest is that, you ought to have an official ROM (check Wiki to download your official ROM flashing EXE), which seems to get me out of trouble a few times.
Also, it maybe wise to check your battery before any flashing attempt, make sure it is 100% (60% will do mostly, but in case of an emergency, that 40% helps). It cases where a phone doesn't go charge/bootloader, it is battery problem. The overnight thingy that you've done, probably rest the battery long enough to boost it to a charge (e.g. how you get a blink when you switch off a torchlight for period of time on a low batt).
Good also among your information, tell us the IPL/SPL/Radio on the ROM you are using.

Hermes wont boot - 4 color bars - help please

Hello everyone. After some researching, this seemed like the best site to answer my question, as I have not found an answer yet.
Yesterday morning, I was running my ATT 8525 (which I believe you refer to as "hermes") just fine. I was using the internet sharing feature, and went to reset the phone. I "believe" I pressed the power button while pressing the "ptt- push to talk" - button. The phone turned off, and when I turned the phone back on, rather than loading like it normally did, I got a new screen.
The screen has 4 color bars. A red bar at the top, then a green bar, then a blue bar, and last, a white bar of color on the bottom. Each bar takes up 1/4 of the screen and runs horizontally. At the top, the phone says, in white text:
HERM100
1PL-1.04
HERM100
SPL-2.03
At the bottom of the screen, in the white bar of color, in black text, it says
SERIAL
Now, when I press the power button to turn the phone off, nothing happens. I have to remove the battery to shut off the power. If I plug in a USB cable, the SERIAL text changes to USB. If I press the top two buttons, the one above window and the one above ok, while pressing the stick in to reset the phone, that screen works ok. I believe it is called a "hard reset" It asks if I want to erase all data and restore factory settings, and if so, press r. I press R on the keyboard, and the screen then says reset complete, press space. I press space and then I am back to the screen with 4 color bars. Nothing else I have tried works either. I have been stuck on this screen with 4 color bars since yesterday.
I took my cell phone in to ATT to be looked at and the sales people at the store say that I am 7 days past my warranty, and that they can't/won't repair the phone, but they would be happy to sell me a brand new one... for several hundred dollars.
So, the folks on the internet are my last hope =( If anyone reading this knows anything, even if it is a link to another site or something, that may help me resolve this problem, I would greatly appreciate it. If not, I at least thank you for your time reading my post.
- Wormling
Oh, as an additional thought, if it helps, I have not used any of these :baked: roms or any such thing. I bought my phone and used it as is. The one and only change I ever did to my phone was I followed ATT's steps on upgrading from Windows Mobile 5 to Windows Mobile 6, if I remember their names correctly. Hope this helps.
Bootloader. This is the name of the screen according to my research.
"Is your device able to boot Windows Mobile OS?
This one is easy: If can you see your today screen and use your phone as a PDA means you can boot OS. If you only see the splash screen, bootloader screen (tri-color) or windows mobile splash screen you can't boot OS."
Got this from the thread at
http://wiki.xda-developers.com/index.php?pagename=Hermes_Unbrick
So, I guess I am stuck at the bootloader screen.
Try a Hard reset - hold both soft keys and reset with stylus. Hold in until it asks to reset to factory (whatever). Press "r" on the slideout keyboard and then space. You should go back throught the setup PPC steps.
YOU WILL LOOSE ALL INFORMATION ON YOUR HERMES...This is unescapable as you would any other way you tried to recover your Hermes too.
I suggest if you get it working to install Hard SPL V7 (makes recovery easier) and also pim backup so you can restore all your contacts/messages if something goes wrong again.
Cheers... & good luck.
I have tried hard resetting many times, and it does not work. It says that it succeeds and that factory settings have been restored, and then I am back to the bootloader screen. I have been to the wiki on bricked hermes phones and recovering from a brick. From that, I ascertain I have a type 2 bricked phone (goes directly to bootloader screen). I tried the MTTY tool, and it says that the NAND write was successful on both commands, but, I am still stuck at bootloader screen. I have since tried installing a few different roms, even in SSLL and HARDSPL modes, and nothing has worked.
What I have not tried is the JPIN fix, as I am not an engineer and don't have the tools or knowledge on how to do that. I also don't know how to do the microsoft operating system download fix (using an emulator?)
** UPDATE **
I think it might have been the mtty commands, but I took the battery out overnight, and when I put the battery back in to try the KITL attempt, the phone booted up and started to do the config. I was happy and thought that the phone was fixed, but when it was done with the configurating the phone, it reset back into boot loader screen -_-
You may need to check for bad blocks. This sometimes causes the problems you descibe as well as spontaneous Hard Resets and occasional soft resets.
Do a search for "how to fix bad blocks hermes" and you should get the info you need...
Hope this helps...

So i think ive bricked my iMate Jasjam but im not 100% sure spent hours reading...

Hey Guys,
Although this is my first post i have been reading and reading up about my iMate Jasjam and all of the other stuff that goes with it... Now whats happened is ive gotten this phone/pda for nothing with a sound issue that ive now fixed , it was running a rom with windows mobile 6.5. It was fine for almost 4 days but out of nowhere it wouldn't come out of idle or sleep mode where the screen is black and you just tap the power button to wake it. So i turned the phone off and on and managed to get it to boot into windows mobile but it froze, after this it wouldn;t go past teh load screen. I then removed memory card , battery and sim , still no boot afterwards... I then attempted to use the SD card to boot an original rom onto the phone but it comes up with "loading" for a few seconds and then just sits in the tricoloured screen and won;t budge.
Unfortunatly it appears the phones never had the hardspl done on it so if i can revive him ill definatly do this so it doesn't happen again... If i turn the phone on now it just hangs on the first load screen , ive still got GSM but im not very able with utilising the table to solve my problem... i was wondering if anyone could shed some light on the best way to try and revive it! it's a great little phone and i was using it heaps and heaps , had and did everything i wanted and would be such a shame to see it go as i got it for nothing, repaired it etc..
Thanks in advance and my appoligies if this is a stupid noob question.
Mick
You could try a hard reset, hold both "soft keys" (above windows and ok keys) while hitting reset, then the "R" on the slide out keyboard then space.
You should also be able to flash it from boot loader. Hold the power and side ok buttons while hitting reset, and you should end up in the tri colored boot loader, flash the at&t stripped rom from there (found in my sig below).
Then you can load hardspl. Then you should be ready for some flashing. Just make sure to flash the stripped rom between the custom cooked roms, it will straighten out odd memory issues (no need to let the stripped rom configure, it seems just flashing it is enough).

HD2 Stuck at HTC Screen, vibrating (EDIT - tried flashing currently stuck at 9%)

Hello,
EDIT - Ok I'm just adding this bit to my post to summ up the whole situation from Post 1 until Post 14 in dot points
- HTC HD2, Began randomly freezing to "HTC" screen, when reset, loads "HTC" Screen and vibrates 5-6 times, sometimes let me goto OS, but at one point stopped letting me goto OS, Stuck at "HTC" Screen with the 5-6 Mysterious vibrations.
- I tried to flash a ROM off the HTC HK Website, 1.78 I think, Stuck at 9%, Those 6-7 Vibrations, tried again, same thing stuck at 9% with Vibrations.
- Tried another factory ROM from HTC HK the latest one, Flashed 100% the first time through, but then does not boot, just stuck at "HTC" Screen with vibrating
- Tried to flash same ROM again, begins vibrating and stuck at 9%
- I wanted to try if some custom ROMS worked, flashed HSPL 1.42 on, while flashing HSPL it finished on the device but on computer I got "Unknown Error
0x1003FF"
- Continued and went on to upgrade my HSPL to 2.08 so I can flash custom ROMS, now I have 2.08 HSPL.
- I tried Artemis Custom Rom for LEO, this one after it finished I think brang me past the "HTC" Screen, it actually said "quietly brilliant" for the first time, and to some Windows config screen where this Error appeared :
ARM11 FATAL ERROR
flash_os_wm.c line 339
- So I tried resetting, and stuck at "HTC" Screen, but No constant vibrating, only 1 vibrate.
- I tried Cheetah ROM, same problem, stuck at "HTC" Screen.
- I tried "NRG" ROM, same problem stuck at "HTC" Screen, well the NRG Screen.
- I tried Kumars ROM, same problem again. stuck at at the bootup screen.
I should mention whenever flashing, on the computer it never tells me what my current Image version is, it just tells me the one i'm flashing to. e.g the "FROM" field is blank. That's it until now.
Also everytime while at the bootup screen, it cycles e.g it will Vibrate, show bootup screen, do nothing, go black... then repeat the bootup screen, vibrate etc etc etc. After ROM is flashed, if I do a soft reset it will just stay at the bootup screen and not do anything at all.
Hard reset doesn't help either, neither does battery out/in, same thing just stuck at the intro screen with all the ROMS I try.
If anybody knows what the problem could be, please post.
ORIGINAL POST BELOW BEFORE EDIT :
-------------------------------------------------
Whenever I turn on my HTC HD2 It's stuck at the white screen with "HTC" in the middle, it will vibrate on and off about 4 times, and after that it will do nothing.
A soft reset with the Red button under the battery cover just brings it to the same screen with the same problem.
Taking the battery out and putting back in does not help, same problem.
doesn't even want to respond to hard reset (Vol down + Vol Up) + Power Button briefly.
When I try to put it into the Diagnostic mode (Vol down + Power), and try to flash a ROM onto it,
It just gives a Error 294, Invalid Vendor, maybe because I was using a ROM that was not Hong Kong, I don't know but I cant try flash again as the device does not respond to anything now (like before but can't even get into boot mode).
So I'm stuck at the moment and can't do anything.
Before this it would sometimes want to start up, and then get stuck sometimes, but now it's constantly not booting up
and begin stuck at the HTC Screen with 4 vibrates.
Sometimes it even boots upto the "HTC" Screen, and doesn't vibrate at all.
And at the moment I can't even get it into Diagnostic mode, doesn't respond to anything other than the reset button.
Any ideas?
Thanks.
EDIT ----- > Now goes into boot mode, I found out that QUICKLY after reset doing vol- and power gets it into boot mode. But while trying to flash the ROM, on my computer it says NOTHING about the current Image ROM on the PC, Trying to update now, this time it goes into a Progress bar on the HD2, stuck at 9%, and funnily enough at 9% it does the same (Vibrate 4 times) thing. and is stuck at the moment.

Keep trying that hard reset method. Make sure both buttons are fully pressed and briefly press power button to get HSPL to appear.
Follow this guide:
Performing a factory reset using phone buttons
1. With your phone powered off, press and hold the VOLUME UP and VOLUME DOWN buttons.
2. While holding the volume buttons, press the END/POWER button briefly and then release it.
3. When you see a warning message on screen, release the VOLUME UP and VOLUME DOWN buttons.
4. Press the VOLUME UP button to perform the reset, or press any other button to cancel the reset.
Thanks for the reply,
Sorry I was editting my post while you were replying, please read it again it has some updates on what is happening at the moment.
Got it to go into boot mode, SPL 3.03 Version, connected to USB, tried to update with HK ROM, stuck at 9% and does 4 x Vibrate, now stuck at 9% on phone and computer.
What should I do now?
Update - Error 262 on Computer (UPDATE ERROR) the ROM utility has encountered a communications errors during the update process
The computer guided me what to do :
1. Remove USB cable
2. Battery out, battery back in.
3. Start device up and flash again.
Device started at "Software update failed", i was able to plug the usb cable back in, and start flashing again.
at 4%, It vibrated 4-7 times while going from 4% to 9%, and progress stopped at 9% Again.
That vibrating I don't know why it's happening.
I even tried updating again, and it does the same thing, vibrates 4-7 times and then stops at 9% update.
Is the ROM I'm using a bad one? It's the HTC Hong Kong one from early 2010,
There is another one I can download which is from Late 2010, but it's SPL Version might be too high.
The reason I'm trying to update a ROM is to get an early SPL, so I can load HardSPL to use Custom Firmware.
EDIT -
Edit - I just tried Hard Reset, but it just goes to the "Software Update failed, please try again" screen. Tried to load ROM on again but still the same vibrating and stuck at 9% during update.
Hi,
Now I tried updating to a later HK ROM, and it updated but still now has the Green HTC Screen with the vibrating. The ROM that did the Vibrating during 3-9% and stuck at 9% was :
HTC HD2 RUU_Leo_HKCSL_WWE_1.72.831.1_Radio_CRC_Signed_15.32.50.07U_2.07.51.22_2_Ship.exe
And the one that Is Updating without problems and works fine is the newer one found on the HTC HK website :
HTC HD2 RUU_Leo_HKCSL_WWE_3.14.832.3_Radio_15.42.50.11U_2.15.50.14_LEO_S_Ship
This one it lets me update all the way through, once it's complete the device goes black and does not respond to anything, Battery out and battery in and the device starts up, but goes to the HTC Screen, and then Vibrates 5 Times.
And then does not respond.
What is the problem??
Even tried a Hard Reset, and again it does the same thing.
Boots, Vibrates once on HTC Screen, 5 seconds later, it vibrates on/off about 7 times and that's it, stuck at HTC Screen.
Since those 2 ROMS don't work, is there any ROM or Software that I can try to put on that will let me somehow get my HD2 Working again.
I had the same problem. I fixed it by flashing radio version 2.15 and then re-flashing hardspl. Then i installed a custom winmo rom. After that my phone was fine.
Sent from my HTC HD2 using XDA App
UPDATE !!
Ok this is getting very weird.
So I tried to flash the Later ROM that ORIGINALLY WENT ALL THE WAY THROUGH 100%.
THIS TIME, IT GETS STUCK AT 8%, and then the phone Vibrates 5 times just like the earlier ROM.
Does anybody know what this vibrating is indicating? I might try to ask HTC, but even though they developed the phone they would probably be of no help since they sent me a faulty phone back from Warranty.

Just info, I read that some users reported the same as you. And unfortunately, they have to bring it to HTC repair as this might relate to hardware malfunction.
If you are under warranty, you better bring it for repair.
Cheers

+1 for this. Most recently, there have been some users reporting multiple vibration patterns (usually 7 times) when turning on the phone. None of them was able to flash any ROM to bring back their HD2.
At least, most of them were able to install an original SPL before sending it to a service center. However, I never read anything about the final outcome.
The phone has already been through warranty once, and HTC's slack attitude and approach offended me greatly. They wrote on the paper "No Faults Found", which shows their reluctance towards fixing their faulty phones that they are bringing out to us. They just reflashed a ROM with appeared to "fix" the original voice problem I was having, but I didn't have enough time to test the phone out before it began malfunctioning and vibrating on startup when they send it back to me.
And the fee's and costs to get it to Hong Kong are just not worth it, having to pay the postage back from Hong Kong, plus to receive my HTC in worse condition than it was before I sent it to them.
HTC isn't what it used to be
Hi,
So i tried flashing to an older ROM I was shown to by users on the HTC HD2 forum,
It was 1.48, and It flashed all the way through, so then it didn't let me soft reset after the flash I think, so i took the battery out and put it back in.
After that It didn't do the vibrating, only vibrated once at the HTC Screen but was stuck at that.
Now though I am at SPL 1.42, so any point in trying to put HardSPL on and going to a Custom ROM? I just haven't been able to get any ROM to boot up yet past the HTC Screen.
Trying to reflash with the same ROM again this time it's stuck at 0% All the time.
So i tried updating to HardSPL, It got past the "We hacked it" Screen, but after that when it went to the Progress bar on the HTC HD2, on my computer I got the Error :
Unknown Error
0x1003FF
However now when I go into boot mode, It shows that I have HSPL Installted.
Now that I have HSPL, any tricks or Firmware I can flash to try fix these problems and try get a ROM working/booting?
I'm using Windows 7.
Another update - I put HSPL 2.08 on so I can flash Custom ROMS (well most of them i guess).
So i got Cheetah's ROM, I flashed it on and then after it was on, the HTC SCreen appeard, and then the ROM Version in Red letters at the bottom, but it did not boot up, so I did a reset, and then the HTC Screen comes up and is stuck at it.
UPDATE -- Did battery out / battery in, and It GOT PAST THE HTC SCreen, it displayed the "quietly brilliant" text, then it got into a windows screen, but then the Error
ARM11 FATAL ERROR
flash_os_wm.c line 339
I can't click "OK" on the window either its frozen.
A soft reset brings it to the "HTC" Screen with no more.
Battery out / in brings it to the Same "HTC" Screen but then it turns black for a sec, flashes,
then back to the "HTC" Screen, with no Red letters at the bottom, and it keeps going black,
then vibrate and back to HTC Screen continuously.
Sometimes though it will just be stuck at the "HTC" Screen with no Vibrating, just that screen.
I just tried flashing with the "NRG" ROM, I can't get past the "NRG" bootup screen now, soft reset or battery in/out does not help.
So far have tried 4 different custom ROMS, All give the same problem, stuck at the intro screen after the flash.
Also the installer on the computer doesn't say what my current Image is.
Any help greatly appreciated.
hello,
please try the following.
On the back of your phone, the battery cover (metalic) comes over 2 small metal pins. The phone will detect if these 2 pins make an electric contact, aka if the backplate is mounted. Some HTC have either microcontracts or magnetic sensors to prevent a phone to be flashed or to boot with the battery cover missing or improperly attached. This is because without the cover, there is a greater risk to have the battery disconnected or to fall, thus interrupting a reflash process.
Older HTC's would either prevent a bootup in case of missing cover or simply didn't start-up at all. I don't know what's with hd2 but i had one of them with exactly the same problem, and knowing that i checked those small metalic pins. One of them wasn't making a proper contact with the metalic cover, after i fixed that the phone was able to corecty flash a stock rom from the microsd card.
However, i repeat, i don't know if this is really the case with HD2, i may have just been lucky. One more thing, if in the end the phone woun't recover from this, i suspect a nand memory corruption. Kind of like bad sectors on a hard drive. Back some time ago, i only manage to fix a broken device with this problem after doing some welding on the cpu and connecting the board with a pc via jtag interface. Then i could mark the bad sectors as "unavailable" and correctly flash a bootloader.
Sorry for the english as i live in a non english speaking country.
LE. nevermind that, did a hardware check with some equipment, the battery cover issue is not the case with HD2. The problem seems thermal related, - if you cool the phone to 5-6 degrees celsius, the problem should either dissapear or occur less frequently. I suspect the CPU soldering to be crappy in this model, so when the chip heats up the small solder balls (the chip is BGA mounted) either don't make a proper contact due to dilatation in the chip itself or the solder materrial. Aah, i really don't know how to put it in english. However i still have a hd2 with this problem. It's worth disasembling it and trying some fancy soldering with a smd rework station.
HD2 vibrations
By me it was HARDWARE problem.
Try to give phone to 5 celsius for few minutes. After try to flash.
By it works, but after doesn't want to power on.
