After upgrading to WM6, every works perfectly. But then, it seemed randomly, the display is blank/ all white, but I can the phone is still functioning, because i can tap on the screen and get the tap sound. Soft reset and hard reset doesn't work. I'm doing the hard reset blindingly since the display is showing nothing, guessing the key push (i pressed record-camera 3x then mail button). I'm pretty sure it did the reset because after about 30 secs I get the beep that comes on when the screen is showing Tap to setup your device.
I figured it might be a loose lcd cable, but if go into the bootloader, power+record+reset. The display works fine! Showing Serial V 2.07.
I took apart the BA anyways and made sure the lcd cable is firmly attached. It didn't work.
Sometimes the phone would go back to normal randomly, or if I let the backup battery drain, but not always. When it goes back to normal, the clock is always reset to 2004 12:00 AM.
Can anyone help me? Is it possible to have a loose LCD connector which won't be able to show normal display, but can show the bootloader normally? Or is it caused by something else?
Here are other things about my BA that may or may not be related to the problem:
-Can't use DOC_Repart to resize storage, I'm getting the FL_IOCTL_FORMAT_PHYSICAL_DRIVE failed as described here http://forum.xda-developers.com/showthread.php?t=255585
-When upgrading the upgrade program can't detect my current OS version (showing blank under "Your device is about to be update from:"), but otherwise the upgrade works fine.
-I tried Helmi R0, PDA Viet , and xplode's 6.00 roms. They all give me the same problem
Thanks.
I am also experiencing the same issue... currently phone is at white scren, but using My Mobiler i can see my desktop and see that the phone is fully functional, just white screen so cant use...
Mine too. I can see the display working perfectly using SOTI pocket controller pro. So the phone seems to be functioning except for some reason the screen is showing all white screen.
cubangt, are using an extended battery or the standard battery that comes with the phone?
Have you tried flashing with a different rom??
Sorry, I fear my message won't be useful at all for you, but I'll post it just for the record. I hope you can find the solution to your problem anyway!
My BA now can't show anything but a white screen because of what I think is damage to the screen cable (while sliding the display the backlight goes on and off...).
But the cable is not loosely connected, it is sort of strongly bent at one point, and maybe some contacts got kind of cut. Now it does not work anymore, but some time ago switching it off and the on again used to do the trick: the display would be readable again (even though with annoying colours, stripes and so on). I don't think this is your case, but I'd like to warn the newbies like myself that they should care not to lose any piece while changing the LCD on their BA: I think I probably forgot about some sort of protection which could avoid damages to the cable in its movement.
As for the missing version number when upgrading, the same has always happened to me.. I think.
Ok, sorry for my English, I would have had some troubles with exposing these few silly things even in my mother tongue... bye... and good luck.
I tried 3 different WM6 roms. And if I remembered correctly this also problem also occurred for a brief while I downgraded to WM2003SE while trying to resize the storage(which failed).
Yeah I'm not sure if mine is a hardware problem, since I can always go into the bootloader and the display works fine there.
I have new info to add though. I found out I can reliably get rid of the problem by draining the backup battery. Now I have a new question, since draining the battery takes a while, is there a way to reset the phone as if the backup battery is emptied (and return my display to normal)? If I can find a way to simulate this, then I can actually use my phone again, even if I have to do this once a day.
Obviously soft reset doesn't work. And I don't wanna do a hard reset either. Maybe the experts here now what kind of data is reset when all batteries are completely drained.
Thanks for the help
hmmmm
quick thinking.....i was working on my phone tonight and came across this thread.....if not grounded properly it could be that you statically fried a component in the process?
On Saturday night i was txting playing beer pong having a good time.
When all of a sudden a black screen came out saying something about how it was goin to restart and reset or something like that and that all my personal info would be gone.
So i did it and once it restarted it just stayed stuck on the boot up screen.
Not thinking twice about it as i was having fun i just put it in my pocket thinking maybe its gonna take a lil longer but then i realized after awhile it was still on that same screen.
I took out the batter turned it on again same thing happened.
I gave up and decided i'd just deal with it the next morning.
Next morning comes its now like around 1-ish crazy party haha
Point is phone is dead i charge it for 30 min? i try turning on and nothing.
So then i boot up pushing both buttons figured i would do a hard reset.
Still nothing!
My friend decides to take me home so i take this time to charge my phone a lil more with his car charger and at first it was charging then out of no where it doesn't charge?
No light?
No boot up?
Nothing?
I take the battery out and back in then plug it into the charger and the light doesn't turn on but my phone just starts vibrating uncontrollably...
This freaks me out so i take the battery out and again same thing.
I took the battery out for a couple minutes then put it back in and it started charging again.
yay!
Oh btw the whole time this happened i was able to get into bootloader mode so i figured it cant be bricked and i can fix it just got to charge it.
I got home battery wasn't that charged but i plugd it in to my computer in bootloader mode hoping it would charge for a bit then i downloaded a new rom and i read it was a good idea to use task29.
Sounded like a great idea to fix my phone.
I got the Repack by ShaDrac and flashed it on my phone.
One strange thing i did notice was that usually when i flash it i see HTC then a progress bar.
This time it was just blank all black but with the progress bar i saw it go all the way to 99% and 100% on my computer it even said successful flash.
But after that it just stayed off?
No reboot ?
NOTHING!
wont charge
wont turn on
no bootloader mode
completely bricked.
im sure the battery is just dead since it wasn't that charged to begin with but i have no way of charging it!
I did a lot of googleing and found no answers i refuse to believe its bricked!
it cant be rite??
If anyone could please help me i would really appreciate it.
Ive only had my HD2 for about a week =[
Oh and it's a T-Mobile US version unlocked.

If you have only had it for a week then the best thing is to just take it back to wherever you bought it and ask for a direct replacement as it should still be within the time frame for that.
Sounds like you have done everything possible to bring it back, taking the battery out, hard reset. If it wont turn on, wont go into the bootloader and you cant get an activesync connection then theres not really much more you can do.
Mark.
yea i agree, dont waste time fiddling and trying to bring it back, get round the shop today.
Unfortunately thats not an option as i got it from someone else and then unlocked it since im on at&t. At most i would have to call htc and hope the manufactureres warranty can do something but i highly doubt it.
cant believe this is the end of my HD2

You might try taking the battery out and leaving it out for at least 24 hours. Sometimes that will reset a few things and bring the screen back on but im not guarenteeing anything. Yo uhave nothing to lose at this stage though. You could also try connecting it to your pc via activesync and see if it connects. Even if the screen isnt coming on you might still get a connection which you could use to flash a new rom.
Even getting a replacement battery off ebay very cheaply might sort it out as I have heard of batterys going funny before.
Just a few sugestions.
Mark.
all the phones should (I think) be manufacturer warrantied for the first year, so I bet htc will fix it, though you might have to pay shipping.
dig out your regions htc repair center and get in touch. so long as they can't see the hspl it should be free.(
I dont have HD2 (<--nexus one), but one thing i have noticed with all HTC phones that I've had something similar happen is when i have tired to reboot the phone by turning it off and then trying to turn back on it wont. I would take the battery out and still it will not. I would do the same with the sd card and same but what fixes it is taking the SIM out press the power button few times with no battery and then putting everything back on and it turns on. It happens in a while. Maybe not the same problem but i guess its worth a try if you haven't yet. One more thing I would try is to take the battery out, the sd card and the SIM card out and then plug your phone into the charger and wait a few mins to see if the led or screen would come on. Try the same thing by plugging it to your computer. If computer does make sound and it does detect your phone then it might just a screen related issue which might be the case since you already flash it with a different rom and nothing came on. I know you probably have tried this but you didnt say in your post but have you tried this?
1. With the device turned off, press and hold the VOLUME UP and VOLUME DOWN buttons, then briefly press the POWER button.
2. Continue pressing the VOLUME UP and VOLUME DOWN buttons until you see this message on the screen:
“This operation will delete all your personal data, and reset all settings to the manufacturer default settings. Press VolUp to restore manufacturer defaults, or press other keys to cancel.”
3. Release the VOLUME UP and VOLUME DOWN buttons.
4. Press the VOLUME UP button to perform the hard reset, or press any other button to cancel the reset.
Good luck
I agree with mskip about the 24H thing if you let the internal/backup battery die it could solve a possible brick then by reflashing
also what deanesn said about the HD phones its also true (same prob with G1 and excalibur) sometimes out off nowhere it wont turn on or its just going to give you a black screen... wierd huh!?
important things I wanna know is
what rom where you using? what radio version? what were the last app or apps you installed on your HD2?
anyways from what I've read&done ever since I joined XDA this is the best thing to do in a situation like yours
This is when you get a black screen
1 if its stuck on the boot screen try to do another hard reset
2. if you cant or nothing happeneds try to see if you can acces the bootloader screen
3. if you cant, remove the batterie for like 24H or maybe more so the internal batterie dries out (if you do that make sure that you try to estimate around 50% to 70% before removing the actual batterie for reflashing)
4. then insert the batterie and try to acces the bootloader or hard reset by pressing the key combanations dont try to see if by a miracle chance it would fix the problem (trust me at this point it wont)
5. if it actually DOES bootup find and download THE STOCK ROM FROM TMOBILE
6. HARD reset if nothing then do it agn but before it has a chance to, try to boot up
7. quickly acces the bootloader wipe your phone (task 29 for hd2) and flash the STOCK ROM (not a custom rom. I read somewhere that its always better to go with an official tmo rom)
thats it Ive try many things on my ALMOST bricked situations this are the things Ive done MAYBE IT WONT WORK FOR YOU, one time I thought my excalibur was dead until I left my phone without a batterie for like a weak then later out of nowhere it boots up only on the first tmobile splash screen and I was able to fix it
LOL even tho those steps prob dont apply to you what you can do is call HTC and tell them you have a black screen on your htc DONT TRY AND ACT all smart by telling them you have a brick and you had a custom rom and all of that cause that prob voids your warranty with HTC, from what I've read this one guy told them that his girlfriend was texting and then the phone froze and the she remove the batterie and the screen went black. And he got a replacement
also another one that I read is a guy telling them he was doing an OFFICIAL ROM UPDATE and the phone never turned back on.
hope it helps
Mark:
Thanks, and this is actually my plan lol I used to flash my old motorola rizr all the time even had to testpoint it to bring it back from a complete BRICK! but the one thing i couldnt fix was water damage haha but after a week of having the battery out some how... miraculously it came back
Deanesn:
How is the nexus one? I was gonna get a nexus one or a hd2 but the screen size ended up being the tie breaker although ever since my g1, android has had my heart haha
Ive always hated windows mobile but the hd2 was perfect!
I also agree with what u said, i have seen those symptons before.
But yea thanks on the advice.. sadly... already tried it and nothing.. =/
Tuppaacc:
Thnx thats exactly what im trying to do.
My only problem is my battery is dead and i need to charge it!
Oh i just noticed i forgot to answer ur questions Tuppaacc.

I was using Duttys_Leo_Sense_2.5_5.2.21898.5.0.91_2.10_Radio_2.08.50.08.2_HG_V1.7_WWE Rom.
Im not really sure what radio i was using but if i had to guess i would say 2.10 since i dont remember flashing anything else and i heard the best radio was the one the HD2 already came with.
As for the last app installed ummm.... iGo8? not sure either but in total all the apps installed where
My Phone

Facebook

iGo8
Aim
Flashlight
Glympse
umm cant think of any other ones. I know i didnt install much just had flashed the rom the night before.
again sorry for skipping your question.
try
try taking sd card out and boot it work for me
Here is what you have to do after I made a mistake and "killed" my US version HD2, but it's back to service.
First of all, you have to be sure the battery has at least 50% left. If the unit is able to charge the battery, leave it charged for a couple of hours.
Second, unplug all the cables from the unit, take the battery and wait for a few seconds, then put the battery back in. Press and hold volume down button and press red (end/power) button once. If everything goes well, you should see a tri-color screen.
Third, plug in the phone and run ROM update again.
WARNING: flashing will erase your personal data.

You need to get a desktop charger so you can plug the battery in and make sure its fully charged. I dont think they are available from shops but you can buy them online (ebay) for around a fiver.
http://cgi.ebay.com/Desktop-Battery...&otn=8&po=LVI&ps=63&clkid=9087015918333818927
That one says for the T8585 but im pretty sure they both use exactly the same battery. You might want to check on that though.
Mark.
My goodness, that OP is a real doozie.
That's pretty wild man, although I don't have much input, other than the obvious suggestions that have already been provided for you... I will say that was a worthy read.
Yea thats pretty much my only option I will be buying that desktop charger real sooon and ill get back to the forum with my results.
Cant believe they are so cheap haha
Ive even seen one that comes with an extra OEM battery and charger for under 15 dollars!

Thnx for all the help and support. =]
U have a Bricked HD2 my friend
i bought the wall charger and it charged the battery but it still wouldnt turn on or go into bootloader mode or do anything!!
=[
..
any luck with un-bricking your HD2?
Seems like OP bought a damaged phone in the first place or something, or something "happened" on the night of the party. Beer got on it, perhaps?
Hi everyone, I'm new to this forum (first post), I've owned my Continuum for a few months now happily with no problems. I actually love the phone! But recently I ran into a pretty big problem...
Let me give you a little background on my phone first, I have used SuperOneClick on it, to grant super user permissions, I've used the program to grant me access to the phone tethering apps that are out (currently using Open Garden), and the AdFree app in the market. I havn't used anything else in regards to 'hacking' my phone so I'm a bit confused as to why I'm getting trouble.
Anyways here's my problem, lol! Well the other day I turned off my phone and tried turning it back on and I would get a grey battery with the spinning disk, and it wouldn't turn on :\! I tried holding all the buttons, for over 10 seconds, no avail. It still turned on to the battery and nothing. I tried taking the battery out for a whiiiile and nothing. Eventually I plugged in my phone to the wall and it magically worked. Actually that's the only way I've been able to get my phone to turn on lately. It works fine once it's on but every time I turn it off the same thing happens .
So that's truly why I'm here... Is my phone 'bricked', or are these some symptoms of being 'bricked'? Are there any fixxes I can go about taking to you know...fix the problem ?
Any help would be Greatly appreciated,
Thanks everyone,
-Matt
Oops, I forgot to mention that my phone has been acting strange sometimes in the sense that I plug it into the wall and the 'Mass Storage/ Media player' option comes up, even though it's not plugged into the computer, just into the wall.
Pretty strange huh?
Anyways thanks again everyone who helps!!!
Can you try taking out the battery, then putting it back in...
Then hold down the volume down key as you power it back on?
I would try un-rooting and doing a factory reset... that should eliminate software issues... If you're still having issues then take it to VZW and let them give you a new one.
This is not "bricking"... If a phone is "bricked", it does nothing, absolutely nothing, and the only way to make it useful is to use it to build something.
Sure, right now it says "Downloading... Do not turn off Target!!!".
Thanks for letting me know it's not bricked, that's a little reassuring .
After a while I just took out the battery and stuck it back in and attempted to turn on the phone the usual way, and it turned on just fine. I'm guessing it's fixed and hopefully it won't do that again.
Hello all. First let me state that I rather not make a thread to ask help on a problem that seems to have happened to a few owners, but my knowledge as to how I could resolve the issue is severely lacking..
At some point today my phone was ringing but the screen would not show. I thought about taking the battery out and turning it back on but there would be no HTC, Bootanimation, anything. It was Just a black-lit screen which responds due to tactile feedback and the four touchkeys light up as usual. At first there was an odd sound that would play after a few minutes so I decided to charge it but again there was nothing. Even tried to access bootloader with -Vol and Power still no screen.
I asked a friend of mine to call my phone to see if it would ring but they said it instantly goes to voicemail as if my phone was off. Note that I WAS SURE IT WAS ON.
Adb seems to work with it as it seems whatever I need to do I have to do it through there.
G2 rooted with gfree method
CM7.1 RC1
Clockwork Recovery
Again i am sorry if I bothered those with posting something others would think is "too common of a problem" as I have no experience in fixing this issue. Plus I would like to try any option available as I would not like to try and have my phone replaced (because of the risk of discovering root and obtaining a G2 with stock gingerbread which is currently not rootable)
Please help..
It sounds like you're suffering from some sort of hardware failure. You need to send your phone in for repair/replacement.

Same issue here...
I'm facing the same issue, when i try to unlock the phone (power button or trackpad) the screen lights but stays black, and the buttons are also backlit. I have to lock again with power button and unlock again to get to the actual screen.
It first happened a few days ago, and since i didn't reboot/restart in weeks i tried to reboot but the same issue comes back.
then i shut it down, pulled the battery and then back, and restarted: the phone goes directly to that black backlit screen, i tried several times and tried recovery with no luck, so i thought my phone was messed up although i did have some haptic feedback, well in fact the phone was actually booting, but just not showing anything else than the backlit screen; i waited a minute or so to the booting completes (still shows nothing), then i lock/unlock the screen again and there it is, asking for the pin code.
I tried to go to the recovery again to try to wipe dalvik-cache, i know for sure it goes to recovery, but with a totally black screen, not even backlit this time; the trackpad is too sensitive in the recovery to just blindly navigate in the menu, so it is not useable at all.
Then i had the idea to go to Rom Manager, i reflashed the rom from my sd-card, and enabling wipe dalvik-cache, which worked (all through a black screen). After a few minutes i "felt" it rebooting (vibrating) but still back to that black backlit screen, and i locked/unlocked it again and back it was asking pin code...
I also tried to roll back recovery to 3.0.2.4, since i remember i updated it a few weeks ago, but still the same issue.
I don't know what else to do without accessing the recovery, i wanted to try another kernel, or remove the trackpad wake... is there a way to do it via a script? I guess it's what Rom manager does...
Next step will be a total wipe, but i need to make some room on my sdcard for backup purposes first...
If anyone has an idea to sort this out, i'm highly interested...
I'll try to get a logcat, maybe could give a hint
Edit: Virtuous sense 2.0.0 (used it with no issue since it came out, could it be a hw issue?)
Edit2 : attached logcat
Is the pin screen differant than the usual one ie white number keys? If it is that's the sim lock screen you need to call the carrier to get the code or find out the default. Or just get a new sim lol
nah it's the 4 digit pin code, i didn't lose it btw, it's still working and i can use the phone, but i have a black backlit screen whenever i want to wake the phone, and thus when i receive a phone call, i don't know who it is and i blindly press/swipe the screen to answer, because if i want to use the same trick of locking /unlocking, it doesnt work as the lock button is also used to reject a call...
Maybe rip and reinstall the phone app?

I have the same exact problem as this EXCEPT, it's intermittent. Sometimes when I wake the phone I get an all black but backlight screen, and other times it's fine. I'm on CM7.1.
But a superwipe and reflash will probably fix it. Also don't restore system data on TB
I know i still can use wipe data + cache + dalvik through rom manager, and i always used to superwipe before switching roms, but how can i do that now when the recovery is all blacked out?
can anyone guide me to a script or something i could do while the phone is active, to tell him to reboot to recovery and flash that superwipe?
anyway i'll try the regular wipe and keep the thread updated

On my side if i leave the phone locked more than 30 seconds, it happens 100% of the time; also I noticed that now the backlight blinks 2 or 3 times (1 second blinking) when locked, first a few minutes after locking, and then randomly, about 3 or 4 times per hour; I guess it's getting worse;
I've read on another thread that it could be video cable getting loose, but since mine is still under guarantee, i won't open it right now just to check, if i can't fix by wiping / superwiping (when i know how to), i'll use that guarantee, which is one month left (lucky me)
EDIT: one other thing that makes me think it's no hardware, when the black screen appears because of a phone call or a message, the ringtone and notification sound are both half as loud as they should be, this is all really strange
after backing up my data, i reflashed the rom via Rom Manager, and I wiped data and cache (which equals to factory reset) this time: the first screen that should show the pin code numpad was already a black (backlit) screen!!
Also, thinking about it, i realised that the "flash rom from sdcard" menu in Rom Manager is in fact "Flash ZIP from sdcard": the zip doesn't have to be a ROM!!
So I tried flashing a new kernel this way, also some framework modifications (extended settings, removed TP wake, etc...) they all install Ok, but still this black screen...
Also I was about to flash SuperWipeG2.zip this way, but if it doesn't fix my problem, I will be stuck with a blacked out recovery, as SuperWipe wipes everything including /system; so if anyone has an idea to tell Rom Manager to flash two zips (Superwipe then Rom) i'll be willing to try, or a script to do that;
Maybe i'll have a look of the scripts in Superwipe and in the rom, and put both zips together... don't know if it's possible?
Maybe I'll try the Superwipe alone if I can get a spare phone, just in case...
Other thing:I used the phone's gps for more than 5 hours with the screen lit, and it never flickered even once; so it's hard to believe it's a screen connection issue...
Just to keep this updated, everything i did, including superwipe didn't change this issue, so i sent it back to the technical support (under guarantee) and I got it back today; the report that came with it says the screen has been replaced; so it was hardware finally...
Hi, i have same problem.. Black screen in recovery and during the boot. When the system boots, screen is OK. Sometimes i have also blackscreen when I want to use HW keyboard. I tried 4ext, reflash older versions of CW but still the same. I can see a screen through Android Screen Monitor and I can cotrol it. But phone is blak, only backlight. Can somebody say, how to solve this issue?
So, for other, if you cant see screen, you can use Android Screen Monitor for Windows and connect phone through USB and see a screen.

WAIT one minute... they don't care? where was I when this meeting took place?
I had this issue as well on a spare G2 I had.
The screen was just black but you could tell it was lit, hardware keys were lit as well.
The phone was actually my brothers and it rooted w/ CM7.
I ended up selling the phone as is on Ebay but after some research it was a failure in the hardware for the screen and I found extensive instructions on how to replace it that I didn't wish to do.
I never attempted to get it replaced and kind of wish I did now if they don't care about the device being rooted.
I purchased my G2 before he had his, and it's never had the issue so not sure what to think of it.

Thanks in advance!

I used the same tutorial to change the LCD but after I put the new its just the backlight but nothing else... I will give it another go maybe and have a look again at those ribbon cables! I guess...

I found on ebay: HTC-Desire-Z-T-Mobile-G2-A7272-Slide-Flex-Cable-Ribbon
or I found also with the chassis for a bit more.
Thinking to buy this, it would be great if anyone could confirm that it would help "my condition" ?
THanks in advance!
In terms of cables, yes the flex cables are what you want.

My brothers TMobile S8 screen randomly stopped working. It has no signs of damage anywhere as well. Weirdly, I managed to get the screen to go on one time by pressing some button combos to try to follow a guide to get it into recovery to factory reset it. Upon the phone booting, the battery had 3% and when I went to show him, it was dead. Now after letting it charge, the screen does not work once again and I can't seem to get it to come on in the same way it did before, the bright blue recovery screen.
Is there any software I can use to just attach the phone to it and factory reset it? I mean, I've seen bad phone screens before that have still had images show up on them, even if heavily damaged physically or it no longer responding to touch and showing dim lights. But this one simply doesn't turn on, except the one random time it did, and it was perfectly fine, showed no sign of damage. Any thoughts would be greatly helpful
Is the battery known to be good?
If not replace it. The system will not boot if there's not enough current. It takes a fair amount of power to boot up. A charger can't provide enough to do so...
It boots up fine, I can hear the initial TMobile boot audio as well as the notification sound the phone makes when it gets to the lock screen. I also had it stop charging @80% not too long after buying the phone on release, with some custom ROM I installed. Ofc its a possibility its battery related, since I can't see anything on it, but it was taken care than the average person I am sure
With a custom rom all bets are off. Makes troubleshooting much harder. Possible rootkit.
Firmware and malware aside if it's booting but no display, possible loose ribbon connector, failed display or mobo. That's assuming the battery is good...
Well I did disable/uninstall Superuser from the phone, and I used it for a couple years before giving it to my brother to use. That is a good point about the cable, I will search for images, maybe I can squeeze a few spots to just see what happens

Sometimes just reseting a connector is all it takes. Those are low voltage lines and a perfect contact is needed.
If the battery is more then 2-3 yo it's probably at the end of its usable service life.
Thanks for the input, I will open it up if nothing else works and I will report back if it helps
