[Q] Black screen while in call - Legend General

Hello,
i'm having troubles with the last OTA 2.05.405.2 update on a stock unbranded, sim-free HTC legend.
The weird thing is my screen going black when calling to my voicemail and not being able to get back to a normal screen. So I cannot interact with the phone anymore.
I get the same problem with other phonecalls too but when the other side hangs up, my screen comes back normal.
I suspected an incompatible app so i reset my phone to factory settings, but this didn't help.
My next step was to download the RUU_Legend_HTC_WWE_2.03.405.3_Radio_47.39.35.09_7. 08.35.21_release_130330_signed ROM from the internet and make myself a goldcard. The process of "updating" (downgrading in fact) goes well until i get an errorcode "140" "Bootloader problem"
Is there a way to replace the bootloader to a previous one? How do I proceed?
Tnx

Men, use search... There is a good thread about downgrading.

Black screen while in call -- proximity sensor broke?
OK, I managed to downgrade my phone succesfully to 2.03 official rom.
My black screen problem still exists. Apparently, my light sensor is not sensitive enough.
When in call, the screen goes black, even if I don't hold it to my ear.
When I put the sensor under a bright light, the screen goes on again. So there must be a wrong setting or just a fysical problem.
Does anyone else have this problem (only when in call)

I have the same problem but the screen turns back on when I shake the phone.

I called HTC service today.
the problem could be software or hardware, for software related problems, a hard reset (factory settings) should resolve the problem.
In my case, i had to send it back for repair.

I hope you unrooted before you gave it in for repair. Or did you flash an unrooted ROM when you downgraded?

I flashed a stock rom 2.03.405.4 from shipped-roms.com.
My previous Rom was 2.05.405.3 via on OTA update.
I suppose there is no problem with that.
Tnx for the attention.

Like in2ition, when I move the handset away from my ear while on a call the screen comes backs, but I'm guessing yours didn't. It's most likely a power saving 'feature' as while you are on the phone you are probably not going to be looking at the screen.
Were any other features not working on the phone? Games like Teeter etc?
Anyway, hope it comes back fixed.

Well this adventure is getting out of hand.
I sent the phone back to HTC and they claim the failing light sensor is not covered by the warranty because they have seen some scratches on the cover, not on the screen!
So they send me a repair note of 225€!!!
Be aware that HTC is trying to get out of their responsability when sending back you device.
I'm trying to escalate with HTC but so far (after six weeks) no luck, the call center is holding back the answer...

Viskoze, I seem to have the exact same issue. I am very grateful that you shared your experience; thanks to that I know that returning the phone as high chances of being an expensive move (my legend has scratches too) and I seem to have found a workaround (putting the phone under a bright light doesn't work and wouldn't be as easy):
sliding my finger from left to right above the screen brings the phone back to life.
Even if there is a hardware pb (the light sensor), the fact that pressing the standby button doesn't bring the phone back to life is definitely a bug to me. Hopefully they fix that in a future release.
I will try to remember to update this thread if this workaround doesn't prove to work well, but so far it works 100% of the time.

i am faced with the same issue too. hope someone is able to assist.
This sounds suspiciously like the DSOD problem that plagued the Sprint and Verizon 6700 Units. DSOD = Dark Screen of Death After much research the problem was found to be caused by the SD Card. More specifically having programs installed to the SD card, it seemed power managment was not properly implemented or something and often times when something was accessed on the SD card while the unit was in suspend it would exhibit the same symptoms you described.
There is a long forum post about it here.
http://pdaphonehome.com/forums/ppc-6700-xv6700/79197-regedit-i-have-made-make-6700-more-stable.html
my screen washes out white sometimes
Mine will turn the backlight off randomly when I start to enter a text message or an email... it turns back on after I press a button however.
DSOD? Yikes sounds terminal! As for the SD issue, the screen went dark after a hard reset / rom reflash with no sd or sim card in.
I'm going to send it back to HTC Europe, hopefully they'll swap it? Anyone had any experience with an RMA to these peeps?
Thanks
SOD and White Out Screen
Guys:
Let me share this with all. I got the white out screen of death on my TyTN about a month after I bought it. I would take the unit out of sleep, it would momentarily flash the good screen then fade to white, then black. I thought this was a software issue with something I had installed, so I re flashed the phone a couple of times and the problem persisted. This problem is an issue that needs repair, I'm afraid. I tried contacting HTC about this through their website and got no response. I guess they don't talk to peons like us. So, a week later, I contacted the place where I bought it in the USA, networkingrus.com, since it was still under warranty and they gladly issued an RMA...return merchandise authorization for repair. They said this was a common issue with many TyTNs and I was surprised at their high level of customer service with these guys in contrast with the ignoring I got from HTC directly. Once they received my phone here in the US, they forwarded it to the US agent/wholesaler who then sent it to HTC Europe in the UK for repair. The turn around time for my situation was about 6 weeks, but it was during the holidays, so figure normally it would take about 4 weeks before you get the phone back under normal conditions. They repaired it very well and it works flawlessly....however, they do flash the repaired phone with the oldest firmware HTC has, so you'll need to do a firmware upgrade for your area/country when you get the phone back from repair, as I did. That's my 2 cents on this issue. So, yes, it is a repair issue.
i have this problem when i open my keyboard and in the same time i play some file in media player. then when i want to write sms, document or something my screen blacks out when i stop typyng

Got the same issue, not resolved yet. It happens most of the time while I am typing on MSN over wifi. As MSN is yet quite buged he may be the culpit; I may try to investigate a little more this issue.
EDIT: In fact my screen does not turn completely black; it just loses the backlight.
I have kind of the same problem. A while after I've installed official WM6 only the backlight turned on when I woke the device from standby. And sometimes the hardware buttons stops working, when this happends the lights in the green and red call buttons are on, even when I set the telephone in standby. Sometimes when this happends the orange charging light also turns on, and I get a bright blue flash in the bluetooth light(much brighter than the actual bluetooth light).
I've tried to turn of the standby, now the device never get black screen(it seems that the black screen only happends when I wake the device from standby). But still the buttons locks up randomly during the day...
Now I've downgraded to official WM5. The telephone was ok for a while, but now it shows symptomes of the same problem.
Is this a hardware or software problem?
Anyone else have this problem?

Dead Touchscreen

Good afternoon,
Just wondering if anyone could give me a hand here. I have the Hermes in the guise of a MDA Vario II. On Thursday, I was using a Wi-Fi connection and the handset got really hot and since then the touch screen has been unresponsive. Since then I've noticed that one of the soft-keys looked as though they were stuck on (changed colour as though they were in being pressed), so I clicked the hard key underneath it which stopped the soft key from being as though it were pressed but that didn't fix the matter of the dead touchscreen.
I've also tried cooling the handset down and then trying to use it, but that doesn't fix the matter.
I've tried reflashing the ROM (Black 3.0.1) on the device, but I get stuck at the calibrating the touchscreen step as the touchscreen doesn't work. I can bypass the first tap screen command though, by pressing the power button to put the device into sleep mode and then pressing the power button again to get it out of sleep mode. This also happened when I flashed Black 2.5. The weird thing is that my phone will still ring even when stuck at the calibrating screen step but it won't show the caller; it just makes the ringing noise.
I've got to admit that I'm running out options fast. I don't want to open the device up unless it's unavoidable. I've alread had a look over some of the other issues with touchscreens but I can't find a resolution.
I think you are snookered here. Warranty fix may be problematic with all that flashing. You could open up (warranty voiding) to see if a connector has worked loose, but that is very much pot luck. Repair job at full cost - possibly very costly!! (and not guaranteed to be working when you get it back - often they replace the LCD screen that may in fact not be broken!)
Won't go into details of the screen issue - you'll have read them all anyway.
Mike
Thanks Mike,
I've got it back to the T-Mobile Hungary ROM now (but it still won't get past the screen calibration). I've been talking to T-Mobile to a seperate issue with the handset and they've said that they'll exchange it, so it looks like I could be sorted. My main concern is that they might query why it's got a Hungarian ROM on it; although I'm hoping that they'll see the splash screens and get stuck at the screen calibration so it won't be an issue.

HD2 touch screen doesn't work

Hi guys,
This evening something wring happened with my HD2. Suddenly without any visible reasons touch screen stopped working. Actualy screen itself is working but it doesn't react on any touches. I did hard reset - no luck, screen is working but touch surface isn't, so basically my phone is almost dead :-(
Have you seen this behaviour ? Is there any possible way to fix it ? The only thing that comes in my mind which could cause something like this is static electricity shock, but if it kills HD2 screen I want my money back.
I guess now I should use warranty and this is just after 1 month of usage....
Just a stupd question
Don't be offended by my question, I just want to rule out the obvious.
You're not wearing gloves due to the cold outside?
Greetings
chuelibrueder
No, I'm not using gloves with HD2 :-(
I have the same problem. I believe that the connectors under the screen became loose.
I have send an email to htc and they told me to contact the retailer to check if they can replace the device and if not to contact the service center in Cyprus.
There is another thread about this issue here
i`m sure that warranty will solve it.. just contact your retailer.. good luck
Hmmm,
Yet another one having to go back due to hardware problems....
WB
I loose the touch screen today and the hardware button exept Home i think, i had to remove the battery and i waited 30s put it back and everything went in place, the phone had called one contact when i had the bug.
The only thing that happened before screen doesn't work and buttons : i received an MMS strange, i'm not sure i can rely on my phone
I only installed the 1.48 rom and the 3 patches (audio, sms and sd card)

I contacted the service center in Cyprus and they offered to repair it but they don't have spare parts right now. I've also send an email to the retailer and wait for their answer.
Seems i have to wait after Christmas for a repair or exchange.
The good thing is that by pressing the screen with my palm or giving it a few solid taps it works for some time.
bBeware keyboard layout!
I had suffer bye used hadwritting layout sometime it cause screen doesn't responds
try change keyboard layout not hadwritting
Just had the same thing happen with mine, powers up but the screen wont respond anywhere i press. I have tried hard reset AND soft reset, nothing!
Have just restored factory ROM, and deleted hspdl and dropped off at vodaphone in town. Im gutted!!
really seems to be a production problem: i had to send my hd2 back to htc for screen replacement just 4 weeks ago... same fault as yours: the touchscreen wasn't responding to input anymore!
the last weeks i noticed that many people had this problem too...
wow.. keeping a close eye on this.. guess the same problem from the HD is creeping up to the HD2..
Well im hoping vodaphone dont turn around and say its not covered under warranty etc, I had to [like most ppl] sign up for two years to get this phone, i aint gonna be to happy if i have to spend the next 21 months of my contract without the handset i wanted!
Yikes , yesterday my screen didn't respond either (for the first time). Soft reset didn't work. After taking the battery out and leave it out for > minute it still didn't respond. I pressed the screen a little and then it worked again. Not sure if it was because of pressing the screen, but it did look that way. I hope this will be the last time this happens!
tnx!

Well, it's been a few weeks now and I've had this problem several times again and worse, even after a hard reset; and almost each time I could fix it by pressing the screen/hardware buttons, but that shouldn't be the way, because I don't think it's good for the hardware, so I searched the forum and I think I found the two culprits (maybe a combination of the two):
1. The problem occured exactly the same day I began using my 16 GB card, class 2. It once happened that when I had the locked screen problem I took out the card and it immediately unlocked. But every now and then the phone still froze, even when I took out the SD card if the problem occured.
2. Then I have put off the automatic light adjustment settings and guess what; no more freezes!
It looks like a combination of power settings and use of SD card. I'm not very technical, but even when it looked like it was a hardware fault at first, it now seems it's a software fault after all.
Touchscreen doesnt work
Well F4CK my screen will not respond to touch at all anymore seems that this is a problem that is not well addressed tmobile is sending out a new one but the question is when will the touchscreen stop working on that "new" one.NOT happy at all.
Well this has now happened to me....no touch response but hardware buttons working, screen still displays-- off to JB HIFI as soon as I can to replace.
OOOKK I had this problem when i just flashed my phone with a costum rom. As far i remember my phone fall down once or twice but not something bad. I have the silicone cover and screen protector. If it was a hardware problem i believe that it shouldn't work at all even if you had to use the hardbuttons. Which that was how i would have to use to unlock the screen. I will go back to the factory rom and settings to see if there is any difference. My current rom is AthineOS 3.14 and Radio 2.15.50.14.
If for any reason you want to access your cellphone and you don't have time go through troubleshooting. I Suggest you download mymobiler which connects the phone and you can use it through your pc. Make sure you take the sd card before you connect. Here is the website www.mymobiler.com
In my case, my phone was RIP. The touch screen stopped working after installing a custom ROM. I installed the latest official ROM from T-Mobile and my phone and came back to life

HD2 Touch Screen Not Responding

Hi Guys i hope somebody who knows about capacitive touch screens can help me! I have taken my HD2 apart to fix a smashed camera lense. On removing the back cover i used a small screwdriver to prise off the back case and unclip it all round. It came off with no problem, i fixed the camera and put it back together. When i turned the device back on the touch screen isn't responding to my finger on any screen. Like i turned the touch screen off! The hard buttons still wok but nothing from the screen. Nothing looks damaged (I.e the glass isn't smashed). I seem to think i might have damaged something when prising the cover off with the screwdriver. Please, any suggestions would be really helpful!!!
Can anybody out there help with this? I am currently without a phone :-(
I have exactly the same problem, but it happened from nowhere. I didnot unscrew anything. Please Help
Check the flex cable.. this part are very delicate.

same problem
ive got the same problem, mine just stopped working, i performed a soft and hard reset, removed the battery still nothing. it worked for a moment but once locked it stopped working again, only the hard buttons.
same problem but it works on and off. basically the screen will respond until the phone is put into hibernate. the after that id have to push the phone button and end button back and forth until it responds
Same Issue independant of ROM
Same issue here.
Funny thing is it started a week or two ago randomly out of the blue.
Same scenario:
lock the phone can't get touchscreen to respond for unlock
Judging by these posts everyone started seeing this about the same time, maybe it's a software issue or background app .
Help!
I have same problem. It can work for a couple of hours or in 1-2 days then just stop responding, almost every time when in hibernate. Lets just hope it's not hardware failure.
This started happening to me this morning. Out of 50 tries, managed to unlock the phone three times only. This happened out of the blue, right after i removed my phone from the charger.
Have soft reset, hard reset, reflashed ROM, but the issue still remains.
I really really hope this is not a hardware issue.
Does anyone out there know how to solve this? My phone is virtually unusable right now...
Same problem here, I've been testing for about 2,5 months now and today I've sent mine back to HTC . I think it's a hardware problem, tried everything from hard resetting to reflashing. When I press the HTC logo and keep it pressed the screen does respond again. Conclusion: hardware problem.

You're probably right.
I've also tried everything. But kind of strange that if I lock when not on home tab it seems to work. And the screen, almost always, reacts as it should as long as I just dont' lock it.
I just started to get this issue. touch screen works fine until it hibernates. reflashed, still happens. found this in my search:
htcphones.net/htc-hd2-problems-with-touchscreen/
just got off the phone with tmo. they are sending me a new one.
Yeah, it happened to me as well. I opened a new thread like a month ago explaining the problem: http://forum.xda-developers.com/showthread.php?t=710282&styleid=15
and I contributed in another one concerning the same issue here: http://forum.xda-developers.com/showthread.php?t=708530
Summing all up, it ain't caused by a software or a ROM of some kind (at least in my case) because soft and hard resets didn't solve it nor did the flash of a stock ROM. The most probable cause is a digitizer (touchscreen) defect that appears randomly and totally out of the blue. The only thing to do in my opinion is to send the phone in for repair, which I did. It came back with a check mark on "calibrated screen" checkbox. As of now phone's working fine and I hope they solved it even though I read of other people who have had their leo's screens completely replaced..
A curious side note: htc care reset to zero my phone's call duration timers..
I'm not sure if it's the screen. In my case I think it's the connector from the screen to the motherboard, because pressing the housing seems to help.
But let's see if HTC is able to repair it, I hope they are, because the problem is so random they might not even see it
After losing functionality on my touch screen for a week, finally decided to send it in. Took the trouble to revert my HSPL to original and Stock Rom.
Repair should take about a week. Now I'm stuck with an ancient Nokia 6230i for this week. I feel so lost without my ppc. Have had one for as long as I can remember.
Hopefully the phone comes back okay...
I've had so much problem with the screen not responding so I did all backup then reflashed, hard reset to put the device back to stock. Did this during the weekend, I even fired up my old iphone 3g to have as backup phone.
All set today to go to the store and have it repared under warranty.
But since Sunday evening it works perfect. I've been testing it a lot and the screen has not stop responding even once.
This might be just temporarily but does anyone else experienced something like this?
Mine sometimes worked well for hours... days... but eventually the problem came back.
Mine died on me when I was actually out of the country (stuck in Vietnam without a phone). It would work for 5 minutes, then stop for hours. I would have to switch my phone on and off for a couple hundred times before it worked for another 5 minutes...
Got so tired of it that i sent back my HD2 for warranty repair. Expect it to be back tomorrow (or Friday at the latest). Hope there's no further problems with it.
I hate to say it, but the HD2 is known for its highly defective touchscreen. Even when it's working, a lot of people experience strange and bothering events, such as the touchscreen "touching" itself, a very high/very low screen sensitivity all of a sudden, the tilting of the screen to one of the four corners of the device and so on and so forth.
With a device so expensive one would expect it to work flawlessly. Seems to me that HTC doesn't think the way we do...

Touchscreen does not work

hello, recently my phone's touchscreen does not work. Only when I initially turn it on, it will work until I turn off the screen or if someone calls, I am able to answer then the touchscreen works. Other than that, if I power on the screen, I cannot unlock it at all. I am currently using NAND version of Android on my phone and it have been perfectly fine for weeks. Does anyone have any clue? I have already tried to load a different version of the rom but still the same problem is occurring.
Could be a hardware problem. Send it back for repair.
This is a hardware problem. Send it back to HTC for repair.

Try turning on your screen with the other buttons beside the red end call one.
This happened to me, however, eventually, it stopped working whenever i pressed any of the other buttons to turn on the screen for touch to work also, so it's best to send it for repair while you still can.
For all of you having issues with screen freeze, here is my take. (Before I waste any of your time, I just want to say that I finally had to send it to HTC for repair) This is NOT a software issue but a hardware issue.
I have been flashing roms ever since HTC 8225 came out. I don't want to sound like an expert, but I am an above average user.
I have been using my HD2 for over a year. Then the screen started freezing out of the blue after it locks. Then I had to reboot it and it worked as long as it didn't lock.
Then I figures out that it started working when i awoke the phone by pressing the "BACK" button. So I kept doing that for a while till that stopped working. Then I figures out that if I tilt the phone sideways, almost like changing the screen to landscape, brought it back to upright position, and pressed the back button, it unlocked. However, this also stopped working after few days.
(I also tried to flash many different roms to make sure that this is not a software problem)
Finally the touchscreen stopped working altogether.
Then I called HTC to see if I was still under warranty. I thought I was way past the warranty period but HTC said that I was under the warranty. So I send in the phone for repair and it is on the way back from repair. I didn’t have to pay anything since it was still under warranty.
If your phone is under warranty, send it in for repair as soon as possible. Even if it works for a little while, it needs to be fixed.
I just wrote what I have learned by trying different things. When I flashed factory roms and the screen is totally unresponsive, I concluded that it is a hardware issue.
If you know better, share it with the community!
Thanks for the response everyone.
I have tried to turn on the phone using any other button but the red button and it works. But as most of you already experienced, it will probably get worse. I don't think my phone is under warrantee anymore so is there a repair kit for this?
I have worked on a handful of HTC phones but the HD2 is different. You need to use a soldering iron to remove the touch screen connection. I personally don’t like to deal with stuff like that! As far as a kit, I am not sure. There are videos on youtune which can walk you through changing the screen. Then again, I am not sure what needs to be changed. Is it the screen? Is it the digitizer or something else? Keep searching... Good Luck!
digitizer broken, send the HD2 for repair
Obviously, if you phone still falls into warranty period, reflash original stock WM
good luck
