[Q] Device encryption hangs start-up

Hello,
I recently configured ActiveSync E-Mail on my HTC HD mini. Everything works fine until I power off and power on the device. The startup sequence is paused with the following text:
"Company policy has enabled device encryption. Startup is suspended. Select unlock to continue. Emergency calls: Press talk."
When I select Unlock then nothing happens (the button is pressed).
The device cannot be turned off by power off button (it only goes to sleep).
The problem is not solved by removing the battery, putting it back and powering on.
The only way to get the device working is to hard reset the device by the special sequence of keys.
Device: HTC HD mini
ROM: RUU_Photon_HTC_WWE_EastEurope_1.36.479.1_Radio_Signed_32.2803.05.06_0.63.05.36_Ship.exe
I reproduced this problem 3 times.
I downgraded from RUU_Photon_HTC_WWE_EastEurope_1.36.479.1_Radio_Signed_32.2803.05.06_0.63.05.36_Ship.exe to RUU_Photon_HTC_WWE_EastEurope_1.32.479.2_Radio_Signed_32.2802.05.06_0.63.05.35_Ship.exe which seemed to remove the problem. However, it appeared after several power cycles also on 1.32.
Any idea how to correct this?

I had exactly the same problem when I purchased the HD minn a few months ago. It happened 3 times in a row that I had to hard-reset and re-install for exactly the same reason (no unlock keys after start-up.) I called my corporate's IT department. They said they changed something on my MS exchange policy profile that may help. Frankly, I can't believe that this was the real root cause of the issue but ever since then it works fine. Never had this problem again for 4 months.
Sorry that I don't have a real solution for you.

Thank you for you reply. May I have additional questions?
1. What ROM release do you have on your HD mini? As you had the problem a few months ago it might be 1.32, right? I have the problem on ROM 1.36 when I first time power cycled the HD mini. It survived many power cycles on ROM 1.32 until the last one which caused the problem again.
2. Is there any chance asking your corp. IT dept. about the change they did?
==
edit:
It seems that the responsible one is HTC Sense. I upgraded from ROM 1.32 to 1.36. I decided to test this with HTC Sense turned off. The problem is no longer present on 1.36 when HTC Sense is off. However, it is a workaround only. I informed HTC support and I hope they will fix it.

Same problem as the others, only I found the cause!
Everything works fine on mine (1.36) until I change the lock screen wallpaper. As soon as I change that the device hangs on the unlock screen at start-up.
If you look at the way it all works, on start-up when you are prompted to unlock, you get the standard unlock screen with the slide down option, and a background picture. I'm guessing the default picture is held in un-encrypted memory, and so it works. If you change the picture, the new picture is held in encrypted space and can't be accessed until you add your key. Only you can't because the device has crashed.
One work around may be to assign it a background picture from the SD card. But having only just got the thing to work I don't feel like trying it in case it puts me back to square one.
Update: Yes copy the image you want to SD card and then change the lock screen wallpaper to point at that. Device boots normally with the new wallpaper.
Hopefully this will help someone.

radar: Thank you for your input. The explanation sounds reasonable. I'll test it once I need to reinstall the device. I'll stick with the working status I have for now.

I am in the middle of waiting for my hard reset to complete as I type. I just had the same exact issues as you all described. I wanted to add though that the background I was using when this happened was from my storage card so I dont know if that will fix anything.
Ill try to add anything else I find out. I am going to try this one more time and then forget about my work email if the same thing happens. Or I might try to find a new rom - but I like what I have
Edit: I actually just saw that you (radar) said the image on the card worked... weird. I'm goign to try again. If I could get around this everything will be working perfectly and I'm not ready to give up.

Try disabling HTC sense. It helped me.; I am running months (done several power cycles) without the problem.

[Q] LE E900 Unbranded AT&T USA touchscreen NOT responding! PLEASE HELP!!

I really like my LG E900 phone. I bought it for AT&T in the USA unlocked on Amazon. Installed Mango recently with all the firmware upodates and until today been having a lot of fun with my phone!
All of a sudden today, the touch screen seems un-responsive. The touch screen works intermitently. It starts to work then stops again. I have tried resetting the phone (have to pull battery). I wasn't doing anything when I this happended. I recently installed Tango and Livestrong mobile app, otherwise phone was flawless.
1. Is my touch screen broken?
2. Does anyone have a clue. I thought maybe the phone is running apps in backround but I can't seem to find the problem. The battery seems to drain also.
3. The phone does become operation for minutes at a time but then goes bad.
I wanted to add that the screen is also very slow at first then starts to respond normally. Almost seems to something happening in the backround. As of now, the screen is still not responding. If I continue to play with the screen, sometimes the screen starts to respond, but slowly.
thanks for help!!

In your position, I would try to:
1. Use the guaranty (if it's still active) and take it to a local service
2. Flash a different rom/firmware with all the latest updates inside and see what happens.
3. Buy a new e900...they cost less than ever nowadays...(almost 180€-190€ without a contract...)

You have got to be kidding me, the exact same thing is happening to me, and for 2 days now. I'm unbranded (I believe) on Vodafone Spain. The entire phone has become unresponsive. Drops nearly every call, has rebooted about 50 times in the last 24h.
fUnny thing is, it doesn't ever reboot when I'm actively using it, just during lock screen.
cOuld you further develop your symptoms just in case we have the same issue? Thnx

More Detail about the LG E900 WP7 Lock Screen issue
OK. SO here are the symptoms-
- Whenever I enter the lock screen, the touch is screen does not respond. TO be clear the touch screen senses I am touching the screen but the lock screen doesn't move when swipe.
Ater some research you can find the SAME EXACT error on HTC Surrround Samsung Focus. here's the youtube video. exactly as it appears except time to unlock takes about 2:30 (2 minutes 30 seconds) on my LG
http://www.youtube.com/watch?v=t3QABdcTINc
So here is what happens and what I do
1. Again entering the lock screen, and attempting to unlock the touch doesn't reposnd to any swipes.
2. You continue to swipe and occasionaly hit the physical buttons. This keeps the lock screen on. You have to keep swiping for about 2:30. After 2:30, the touch screen just seems to respond.
3. After the touch screen responds. Nothing out of the ordinary. When I tried using IE, it seemed that IE didn't work as well. Pinch to zoom, swipes not as good. Also portions of the screen are not as responsive.
So maybe start looking for a replacement.
I've tried
- restoring previous OS and files. No change.
- Hard and factory reset. No change.
- changing the brightness setting (AUTO, low) no change
The only thing that I haven't done is upgrade/downgrade the firmware. I think that may help but not clear on what to do.

Are you using the correct charger?
I have an HP Touchpad that has a high output microUSB charger for rapid charging of the Touchpad's battery. Although it hasn't (yet?) given my e900h any troubles, I did read at least one report of a guy's Samsung phone reacting poorly with symptoms similar to yours after using the Touchpad's higher output charger.

I am using a third party USB charger. Not a high power one, but an inexpensive one from monoprice. Ok, I will try.

Some people have reported errors and crazy system behavior when using third party chargers...

Still no luck. Using stock charger now. Will wait to see if any improvements. Thanks everyone.

I was one of them. This behaviour would occur with the charger connected.
I get the feeling the problem the OP and I are facing is also related to chargers, but no longer when they are connected. Charging makes no difference for me, the phone is still reacting very strange.

More Info on failiong touch screen
So
Here are more precise deets
- Whenever the backlight is turned off, the touch screen becomes non-responsive
- The touch screen notices touch but not swiping.
- in order to get the touch screen to respond you must continue touch the screen for 00:02:30 (2 minutes, 3 sec).
- the touch screen will usuallly start to respond to swipes but only a single axis (e.g. vertical or horizontal)
- after 2:30 the touch screen responds like everything is ok.
- the goal is to make sure the screen backlight stays on until the for 2:30. In some lock screen cases, you can issue a voice command, camera etc which effectly keeps the phone one (i.e backlight on) for longer without having to continuously touch.
- issues came after tangoi install and livestrong install.
- wonder if tango did something to lock screen
- also tried changing lock screen wallpaper - no changes
- when installing microsoft insider app, I tried using the wallpapers, but the apps crashes. Changing wall paper using default app works
- using default charger no changes
- received the latest update (fixed voicemail and outlook issues) - no change
I haven't been able to retore/flash NODO. That is probably what I need to do.

same problem here, new phone, original recharger and touchscreen of my optimus goes sometimes frenzy...the frequency of strange behavior raises when I fully recharge battery
i found a video on youtube, but yet i cannot send urls, because i'm new user here, u can find it if u search "problema telefono"
any1 have some solution, pls? or did u try to send the phone back to LG service?

[Q] Broken display

Hello all,
(First of all, if you watch the video you will understand what I'm trying to explain here, but I wasn't able to make myself very clear, secondly I don't have support from asus/google in my country)
I've been using my nexus 7 for almost 4 months and haven't had any problems with it until now. When I upgraded to 4.2 I noticed that the speakers sound was strange sometimes, but most of the time it worked just fine. But today something very sad happened
When I unlocked the tablet I realized it was in my sister's user (I was already at launcher's "home"), so I locked it in order to switch to my user, but when I pressed the unlock button, the screen wasn't normal, it went crazy. I couldn't see anything, just shades of black and white (see video above for details). After that I tried anything but the the screen was the same. Something important to mention is that the screen responds normal to touch input, so I can unlock, open menu, recent apps, etc only by knowing where to touch. I'm even able to turn it off by holding power button and then choosing "yes, reboot tablet" without being able to see anything on the screen.
It worth mention that after several reboots, screen locks/unlocks I manege to get the screen to work perfectly for a couple of minutes, but when I locked the tabled the screen stopped working again.
My question is: DO you guys think that this is a screen problem, some wires that aren't well connected or even maybe Android OS problem? And would it worth it to buy a new screen and try to find someone to change it for me or I should just throw it in the trash?
PS: The tablet is completely stock now, just rooted and with busybox, no OC, no GPU OC, etc...

Try flashing a factory image. If that doesn't work, it's most likely a hardware issue. You should be able to get warranty service if that's the case.

Edit: Missed the part about no support from Google/Asus. Disregard the warranty statement.

Thanks for the answer. I decided to do that (even though I didn't think it would solve the issue).
I turned off the tablet and booted into recovery by holding vol up and down + power and guess what??? when it booted into recovery the screen was perfect again, I could see all information about the tablet, lock state, etc. I decide to reboot it and it has been working normally for a couple of hours from now, I have even made some benchmarks and everything was ok.
Now I'm more confused than before: Hardware or OS problem? The tablet is working now, so I'll just backup all my titanium backup data to my pc and leave USB debugging on, so if the problem returns I'll just flash stock again.
EDIT: After some hours the screen problem returned. I flashed 4.2.1 and the problem was still there. I guess I'll just have to find someone who will open my tablet and see if the wires are properly connected.

Unusual touch screen issue - delayed on start up?

My LG Optimus 7 touchscreen stopped to response with no reason. Nothing was installed or damaged - one minute I called and after turn off and on it stopped to respond. Well - not really stopped but respond in strange way not allowing me to unlock (swipe) lock screen:
http://www.youtube.com/watch?v=QOb54qugw-A
(I took this video after Factory Reset which did not help - that's why it's in German)
And even if I reboot it, no buttons tapping is working, nothing - only this strange unlock screen which moves really slowly and not allowing to unlock.
I ordered and replaced digitiser (dismounted all telephone myself) and this did not help at all.
But I realised yesterday that if I leave my LG with screen open for 2-3 minutes IT STARTS WORKING!! It reacts on touch as it was before! No idea why and how. Unfortunately it goes into unresponsive mode after turning screen off and on, and I have to wait again. So it's useless...
I tried to google and I found few other people experiencing the same issue with different telephones (or tablets). Does it mean it's hardware issue? Is there any point to downgrage ROM - at the moment it's 7.10.8862.144??

(last one of tablet: I have been using the Twist for 4 days and the device is great, only the touch screen seems to be delayed on start up, sometimes it can take up to 10 minutes before it starts working)

Lock screen bug

Just incase anyone else gets it, had a frustrating bug where after using the phone as normal throughout the day, I just went to unlock the phone using the to fingerprint unlock, which it said was unavailable and to use pin to unlock.
Upon inputting the pin it refused to accept the pin, was deffo correct used the same pin for years and years, no way I was getting it incorrect. No matter how many attempts it wouldn't work.
In the lock menu even holding down power I was unable to open the restart or turn off phone options aswell to compond the frustration.
After holding the power button for what felt like forever the phone performed a restart, the phone was able to be unlocked using the pin after the restart.
Had the phone for weeks and this is the 1 and only time it's occured. Just thought I would mention incase it happens to someone else

I can confirm that behavior and also the solution. Had that once as well.

Nearly the same issue here but in my case the power menu to restart the phone "normally" worked.....
