Stuck at tricolour screen after visit to the toilet..

Hi,
A coworker of mine dropped her Diamond 2 in the toilet. True story!
Anyway, since it was brand new she dried it up and if you switch it on now you get to the tricolor screen. I tried attaching it to my pc, and the text at the bottom changed from serial to USB. I now thought I might have a chance to salvage the phone by trying to flash the original rom. owever, even if everything seems to have worked out fine during flashing, the screen (when ready flashing) turned blank only to go back to the tricolor screen again.
Any one have any idea on what to try next? Is it bricked for good?
The screen shows no sign of water damage whatsoever.

The best thing to do in these situations is to immediately pull the battery and put into a bag of rice to absorb all of the moisture before putting power to the unit thus risking a short circuit.
You may still have water shorting out your hardware keys and its putting the phone into bootloader mode.

My wife put her phone on the kitchen counter, well, it got completely wet. In addition to using rice, I put the rice and the phone in one of the vacuum bags and pulled vacuum, left it in for 2 or 3 days and the phone worked and functioned 100%. 6 months later, still up and running.

Thanks for the answers. I think it is as dried up as it can be though. She have dried it with rice etc. Is there any tip on what to do from the tricolour screen?

Hi,
I maybe didn't understand when the screen goes blank, but since the situation looks pretty desperate why not try to install latest HSPL, it's still a flashing procedure and should end up succesfully if you don't have any hardware damage. If HSPL flashing works, you'll be able to flash any ROM you like, official ones included. Since the device is not yours sorry for the silly question: you have WMDC installed on your pc ,don't you?

The screen goes blank after the bar goes up to 100% on the telephone. I have WMDC installed, but I cant get it to connect to the phone, so installing HSPL will be a problem or?

Edit: Doublepost

If you can't connect to WMDC you can't flash anything,I'm afraid...Any chance to flash by putting the ROM image into the SDcard? Problem is that official ROMs come in .exe format while flash procedure via SDcard needs the ROM image to be in .nbh format..I'm sorry, I'm stuck.

You most probably have a hardware problem, probably a button stuck. Try pressing volume up down repeatedly for example 30 times then try to turn on the device. If that doesn't work you will have to disassemble and dry off your device and check for a shortcircuit or some resistivity in the volume down area. Even if you dry your device on the outside, some water still remains on the inside (I know since I'm an electrician).

Sorry for posting in here - my issue is with an opal but it sounds like a very similar issue.
I tried to clean out the stylus holder on my opal with some washing up liquid on a cotton tip bud. Nothing happened at the time, but some washing up liquid must have got into the phone, as the next time I went back to it seemed to be bricked. I didn't know how to deal with washing up liquid so I disassembled the phone and put it into the freezer to see if that would get me anywhere. I didn't think rice would be much use at absorbing washing up liquid. Anyway, a few cycles in the freezer followed by a cold blast with the hair dyer seemed to have the phone able to get to the bootloader, and able to hard reset.
This is where I am now. Hard resets only get as far as displaying:
ONBL 1.27.000
SPL 1.27.000
GSM 03.29.90
with the 'smart mobility' splash below. That's it - after about 5 seconds the phone turns off. I can keep performing hard resets in this loop, and I can also get the phone into the bootloader 'tri-colour' screen where it shows
ONBL 1.27.000
SPL 1.27.000 (all in the red bar)
and then 'F256' in the green bar
the white bar will change from USB to SERIAL as appropriate.
I thought I'd cracked it when I downloaded the stock ROM from htc, and it seemed to run succesfully. However, once it got to 100% it turned itself off again and I was still only able to either unsuccessfully hard reset, or get to the bootloader screen. I've tried installing the stock ROM through an SD card too, and it seems to work again, but same result. I suspect the phone is a brick now, and there must be hardware damage somewhere important. Any ideas appreciated though.

[solved] bootloader dont load

wanted to install wp7 with a clean start...so tried to task29 (doloop) with 100% success and then my tmo hd2 wont go into bootscreen what ever i do...its stuck for ever in "stick together"...i know there is no os to load...but i dont understand y cant my hd2 go intobootloader
so far i tried
with holding volume down and power key with a single tap
with holding volume down and holding power key
with holding volume down, volume up and power key with a single tap
with holding volume down and reset button
with/without sim
with/without SD
with/without plug in wall charger
with/without plug to pc via usb cable
observations...when i pull out the battery and put it back in and then connect to computer when the phone is still off....the charging indicator LED glows in orange.
when in this mode if i switch the phone on with power/end key....it doent start...i have to pull the usb out, the orange LED still glows...and if i tap the power/end key nothing happenes...i have to pullout the battery to get it to start and eventually get stuck in "stick together"..
would really appriciate if any1 can help me get my hd2 into bootloader screen...

resolved the problem myself.....hd2 is working like a charm....thanks for all your support.

How did you fix it? For other users in this position.

SOLVED {bootloader dont loadArrow}
Here is what I did..
B4 that some background -
I used to heavily try different roms/mods and always played with android sd and nand versions…win 6.5X in multiple cooked version….
So my tmo-hd2 has been formatted/hard reseted/flashed many many times
By virtue of this….my screen died….slowly my screen touch responsiveness malfunctioned and eventually died… all hardware keys were working perfectly by the touch was dead….
During the process of screen malfunction to completely dead….made few observations to not things which might help fellow Hd2 owners…one thing is power/end key seems to be the culprit (this is my observation/belief).
Since I don’t live in US spend 100$ in changing the screen since then everything is working well…I still rig my hd2 like I always do…
Well when the wp7 was released, wanted to give a try…did this…hspl pkg 3 spl 2.08 hspl > then task 29 > and my hd2 didn’t get into bootloader at all…..i was doomed as there hd2 (after task29) didn’t hv os..
Searched for the solution everywhere and eventually nothing worked for me…I was about to give up…suddenly sometime struck my mind…wat if the power/end key is the problem….then things were positive..
I opened up my hd2 (unscrew and removed the back panel) and disconnected the connector flex rigid board (A board) of the hardware keypad from the mainboard….and pushed the battery in and pressed reset (sometime u need to plugin the usb cable to wall charged/pc to wake up the phone) and held volume down key and hopped for some miracle.
Viola saw the tricolor screen after eternity – since the back panel (not backcover) was open I help the battery to the pins and didn’t even move my fingers …run the stock rom installation and held the battery tight in place and waited to get the rom completed…the moment its 100% relaxed my fingers and reconnected the flexboard connector, re-assembled my phone and everything was back to normal…
ONE THING I LEARND FROM THIS…..HD2 IS A ROCKING PHONE AND U CAN RESURRECT IT WHATEVER HAPPENS TO IT (if at all some1 screws it with wrong radio…its officially bricked, but still it can be revived using RIFF JTAG method and rewrite boot data).
One final request pls DON’T GIVEUP ON YOUR DEVISE
Now I have wp7 running successfully and waiting for my activation code for live services

also hit thanks if u think its worth it

May I link to or rewrite and credit you with this in my guide?

interesting, two confirmations in this thread, and there's another thread where 2/3 people successfully used this method.
That whole lower right area is the Achilles Heel of this phone, keypad, screen connector and most pressed key all right in one little place.
Bring me the chief designers head on a plate!

Yes. The only downfall of the hd2. I wish it had the soft screen keys at the bottom.

yup...and the interesting thing is, i befriended an HTC engineer and got hold of multiple 'a-boards' at that time to test this out.the flex-board that reacts when we push the button.
there were multiple models/molds for HD2...may be different production lines..everything did the same job including the one which was shipped with the device..'a-board' wasnt the culprit here..the very design of having power + end call + device unlock in the same key/button is the issue.

Read this and be aware please

There is a dangerous in our phone and its caused by us and we have to be aware of that.
As many of us keep playing with our phone an ulocking them , modifying etc for some reason and most time to get out from bootloader we take out our batteries.
What i saw and thought i brick my phone is to destroy battery pins from in /out the battery.
I keep having random rebbots from that cause.
So be carefull with that pins and when you plug or unplug your battery always keep in mind of this as it will be maybe a reason not to find a reason why your phone doing those tricks......
Just plug or unplug your battery carefull...

Thats a fair point.....
You could always just use the reset button though

i bent mine about 10 months ago, bent them back and never had any issues

yeah one of my pins is bent right now every few days my phone does a random reset cuz of it

Yeah, ran into this issue a few months ago, with my daughter's phone. She was just yanking it out and putting it back in like nothing. Thought hers was bricked until I fixed the pins too. But good post to warn others ahead of time, because it can continue to give your phone problems.

I dropped my HD2 a couple of months ago - back cover and battery went flying.. Couple of scratches but nothing major, or so it looked like.
Then I had some major problems with it not switching on, I thought I was in serious trouble.. But a look at the battery pins confirmed the problem was they were bent out of shape and just not lining up (would have happened when the battery flew out with force). Nothing the end of a pen or a small screwdriver couldn't fix!

I pull out and put my battery in almost every day and ive never had a problem.
...Then again im not a retard.

Thanks for starting this thread sotmax. This is a problem that needs to be adressed in my mind. Now I do not know proof positivly that it is a deferents between pulling the battery or pressing the reset button. But I notice very early on when I first got and started using my HD2 that my HD2 would often hang/freeze on boot up at the Orange Windows splash screen. where as when I used the reset button my HD2 very very rarely would hang/freeze on the orange Windows splash screen. Matter of fact ever seens I have recieved my replacement HD2 I have made it a point not to pull the battery out unless the my HD2 is turned off. I have also made it a point to only use the reset button whenever the need for it comes up, andmy replacement HD2 has not hung/frooze on boot up what so ever. I know you have to pull the back cover off anyway to reset or pull the battery, and that it is just a kittle more of a hasle to have to find something to use to press thelittle reset button. I just feel more comfertable using the reset button, I mean the designers of the HD2 oviously forsaw a need for the button and included one with the HD2. So in my mind maybe it would be better for users of HD2s to use the reset button and not pull the battery whenever they experience freezing or any other issue that requires restarting the phone and you can not do so via the external power/end button. like I said I don't know if it is a difference between using the reset button or pulling the batter as far as ghetto software or hardware goes. But my exsperience tells me it might be. Anyone else that reads this and can tell if there is a actual difference between them please post here and inform me and others about this. Plus using the reset button will negate you from having to worry about bending your battery pins.

What do you mean? That people's hardware keys don't break? Just because it hasn't happened to you doesn't mean it doesn't happen. Android requires you to use your hardware keys more, so they wear out quicker... it's a common problem. Why do you think most recent android and wp7 phones use capacitive buttons? Because the buttons are used a lot more than they were used for winmo.
I have always been very careful with my phone and never pushed buttons hard or did anything that would harm them quicker, but my home and back button are both beginning to deteriorate. They still work most of the time, but you can feel they don't have the same resistance to them and they aren't always responsive anymore. My phone is in perfect condition except for that.
So what's your issue with people who are having problems with their hardkeys?

This is a good thing to remember!

You broke your buttons so you're posting this ? I've said before and I'll say it again, Buttons were made to be pressed (don't say it's WinMo, they remain "Buttons" ). They won't make something that would break . Also the warranty does not cover improper usage, try to send it to them and await their response. I doubt you treated your buttons well, I had my HD2 for almost a year and the buttons are still in good shape . It's your fault that you don't know how to correctly use/press the buttons
My HW buttons "WILL" not break unless in an accident

Lets keep it civil please guys ...........

I chuckle every time I read these threads from kids who have broken their phones and then complain that its a fult of the phone not them
Ive had many many phones over the past 15 years and not once have I EVER had a button/pin or any other sort of problem like that unless it was a manufacture fault.
Buttons are meant to be pushed!
Battery pins do not break unless YOU break them. Ive had my HD2 for a year and have constantly removed/replaced battery and have only ever used teh reset button once.

[Q] Going back to stock.

Hi, been trying this for a long time now. I need, for warranty purposes, to return back to stock from nand android. Unfortunately i can't get to bootloader, the tri-color screen. My phone boots directly to Magldr. My phone on/off key is broken and i need it to get to the tri-color bootloader.
My question is, if there's any way i can get the stock winmo 6.5 rom flashed from magldr. USB Flasher, or by CWM, NAND Toolkit, or any other trick so that i can get it to repair?? PLEASE BEFORE ANSWERING NOTE THAT I CAN'T GET TO BOOTLOADER, I DON'T HAVE ON/OFF KEY AND THAT KEY IS NEEDED TO GET TO TRICOLOR SCREEN
My microphone is failling and the hard keys also... need them fixed.
Thanks.

You don't need the on/off keys to go into the bootloader, just the volume down rocker.
Press & hold it, then boot up the device.

Tried it a million times... it's a no go!!! It doesn't work, try it on your HD2, push the volume down and reboot the phone by taking the battery out and back in, or by pushing the reset button. That the only way i can reboot my phone. You need to shortly press the on/off button to get to bootloader.

Okay, try to install Android. After that, from within Android reboot your phone using "Reboot" option . And while it is rebooting, keep the volume down button held.
]P.S[ I just tried rebooting from within android, and then holding the volume down, WITHOUT EVEN TOUCHING THE POWER BUTTON and it went directly to the bootloader. Are you sure your volumes are working ?

You have MAGLDR installed. Power off your phone and connect charger with Vol. down button pressed. Your phone will start in bootloader.

I guess my volume keys must be down too... they work on magldr, they work on android but i can't seem to replicate what you guys are saying. But there's no way i can do this from usb flasher inside magldr?? or inside cwm?? or with nand toolkit?? without having to be in bootloader?

Those are some solutions I have been able to gather from various threads, with the same problem :
Solution #1 :
jonas2295 said:
Okay try this :
Remove battery,
With left hand press and hold volume down,
With the other hand you put the battery back in and press AND hold the power button, so power and volume pressed and hold, wait until you see the bootloader.
This will work (at least it worked on my phone 1min ago)

Some times, Bent Battery Pins can cause unpredictable issues (However, I have not seen one like this.).
You may want to check your battery pins, straighten them delicately if they are (even a little) bent.

No no no no no and NO!!!!!!!!!!!!
There is nothing in MAGLDR that can make your HD2 go into bootloader. The only this.g that can get you into the bootloader besides the external hardware buttons is the bootloader.exe that can be run from inside Windows Mobile. It can only be run from inside Windows Mobile. MAGLDR is a custom bootloader that runs after the HSPL bootloader and has no way of communicating with the HSPL bootloader.
At the OP, you may have a faulty volume button ribbon that is causing you not to be able to boot into the bootloader. Check out this thread you will see what I mean. Read post #10

I had the same problem ...
I could not enter the bootmanager in android brief button press to end a call, we moved the menu to shut down, reset, etc, the same menu that appears when you hold down the button longer to stop calling ...
This defect appeared to me after I lay HD2 due to large changes in ambient temperature ...
After a few days of research, opening, drying I removed the defect, so I pulled out and cleaned the keys below the screen (Home, Menu, Back, red and green) and wipe the foil that these pressures are the same buttons ...

It seems my phone has a little more problems than i tought. I got another HD2 with a broken digitizer,but i can reproduce what you are saying about the volume key down,no need of on/off button. I guess i have to get the courage to open up the beast.
Thanks for all your help guys.

by the way, it's not possible either to flash radio also if i can't get to bootloader??
flashing with fastboot, and .img files and what not is just for android based devices right??

Correct.
If you can't get to the bootloader, you can't flash anything.
Fastboot is only for Android.

I understand that if you are getting the phone serviced directly by HTC, they won't have a problem with you having Android on it. Buy, if you are going through your service provider, that may be a problem.
good luck

I've been to HTC service. They didn't repaired the phone claiming that there was a non original software on the phone and there was water between the digitizer and the screen. Even though none of the stickers were showing red or pink or other color than white.
In fact there is something trapped inside but it may be alcohol. I had an accident with the phone on a boat. Got wet by a wave and it must have gotten to the phone too that was inside my "purse" (it's a man purse ok?!? those bags that we guys use to carry stuff!!). I didn't noticed and instead of taking the battery at once i tried to turn on the phone... all hell brake loose. I then toke the batt of, and let it rest for a couple of days. Then burried it in rice to absorb the moisture. Then read that alcohol could "push" the water out, and splashed some near the hard keys because they didn't work and i thought that may have been salt water, or salt crystals blocking my keys.
Concluding, the phones works with a few limitations. The only keys that work right is the call and the windows keys and volume keys. And my microphone doesn't work right too. People can only barely hear if i speak directly to it and shout, and still they hear me in the bottom of a well.
I've bought another HD2 on ebay, with a cracked digitizer. Was thinking of maybe taking it for parts, since mine is in mint condition. But i might replace it's digitizer and repair the two phones. I'm only affraid to open it up because it looks very, very difficult.
Thanks anyway for all your support.

Hello, i´m an electrician and i have an idea.
Important is to dry it completely before put the Battery in.
I have opened some "normal" earlier Cellphones (not Touchscreen Phones) and cleaned it with distilled water.
It seems to be impossible to get the functions of the Hardkeys back without open your Phone.
You may try to flush out the corner of the hardkeys with distilled water to remove possible contamination with crystals or minerals that could cause block the keys.
I remain this would be the last chance before opening the phone.
i can not say what happens when you do this, normaly the componets have no problem with water, only the microphone and the cable connection can hold the moisture for a long time.
I hope i could have helped you with this idea. Please be careful it will be a risk the Digitizer is also in the bottom right corner.
if you don´t want to take the risk bring your phone to a independent (not HTC or Service Provider) Phone doctor.
excuse my bad english

[Q] HD2 won't turn on — short vibration and black screen

Hi everyone,
I would really appreciate it if you could give me an advice for my TMOUS HD2 P81120, that won't turn on.
I bought it with some firmware problems, spent plenty of time flashing it and finally managed to install a stock ROM from SDCARD using a fridge (it couldn't install w/o such cooling).
After that, it booted to white splashscreen with pink logo (smth like "Bringing happinness", don't remember the text) and stuck on it. I rebooted, flashed HSPL 2.08 successfully.
After that the device won't turn on at all. When I hold the Power button, all I get a barely sensible short vibration, but the screen stays completely black, no signs of life. I kept it on AC charger overnight — nothing has changed. When I hook it to the charger w/o the battery, and put the battery in, HD2 powers on itself (same short vibration, no other signs of life). Tried removing the sdcard, different combinations of power-ons, still nothing. Tried freezing it again for 5-10 mins — still no luck.
Please let me know what else I can try.

and one more thing — when I plug the USB, the PC doesn't detect any device.
It seems that a JTAG is my last resort, still I'm not sure I can find the hardware for that.

the problem is that your HD2 are overheating so the only thing thats left in your case is to replace motherboard

Good point!

Make sure that none of the three pins on the phone that touch the battery are bent. One of the causes of constant reboot is when one of those pins are not touching the battery. Please let me know if it worked for you...

That were definitely not the battery pins.
If anyone cares - here's how it ended (or not yet )
I found a JTAG service in my city, they wanted 50$ to restore the device to a working condition. I agreed, they took the phone. After that they've called me and said they have restored the bootloader, but can't make HD2 actually boot (they flashed stock ROM directly through JTAG, but it always got stuck on "Stick Together Screen". Now I understand I have probably flashed the wrong rom/radio — that's what has bricked it. I paid them 7$ for "diagnostics" and got back a phone with a working bootloader.
After that, I used the "fridge" method to flash latest radio for HD2 and some custom Win6.5.3 ROM (10 mins of fridge before each step). Then I cooled it again and put the cold phone on a frozen chicken (still laughing on that). Guess what — it booted into WM6.5, I even managed to make a call, though it rebooted in 3-5 mins. Overheating problems confirmed, at least it's not a complete brick.
What I've done now is found a guy that will try to "reball" the CPU's BGA - sort of "reheat" the chip to get a firm contact of it with the motherboard, and solve the heat problems. He'll call me today and let me know how it went — i'll update this topic.
As a conclusion, I can only say: "Check three times what you're flashing before you actually are flashing". Otherwise, JTAG is a wonderful "resurrection" solution, although a bit pricey (my case is pure luck).
