[Q] Help! HTC HD T8282 doesn't respond at the password screen

I just set a 4 digit password on my HTC HD T8282 a few days ago. Its worked fine for several days - when I turn it on and enter the 4 digit code, everything is fine. But a couple days ago I turned it on and the password screen shows the number pad, but when I touch the numbers, nothing happens (usually I would see an * for each digit I press), but nothing happens when I touch the digits now, however I can press the "Menu" button on the bottom right of the screen and get a selection of Reset Password or Cancel - but the only option that can be selected is cancel (the 'Reset Password' option is greyed out).
Any idea how I fix this, I can't use may phone now!
I'm trying to avoid doing a hard reset if I can.
Any suggestions???

it might be an issue with your touch screen calibration, have you tried connecting and controlling the device using a windows pc and mymobiler?

Interesting! I did notice that the screen calibration was off one day and recalibrated it and everything seemed fine after that. But I'll definitely give this a try! I'll let you know what happend too.
Thanks for the quick response!

I downloaded mymobiler v1.25 and intalled it. My PC is running Windows XP and I use ActiveSync v4.5. ActiveSync is able to connect to my pnone when its connected to my PC but I can't get mymobiler to connect to it.
I see the mymobiler icon in the system tray but it gives a "not connected" message if I place the mouse cursor over the icon. Also, if I click the icon and get the menu, even if I click "Connect" nothing seems to happen.
Also, the mymobiler screen doesn't show when I select "Open Mobiler".
Anything I'm doing wrong?

that reminds me of the question i should have asked in the first place:
did you set the password with the windows mobile built-in security feature or using a 3rd party software?
background: the windows mobile's own security is meant to prevent proper activesync connections, because, without entering the password, you are not supposed to be able to sync data or access the phone, in that case, activesync should ask you for your 4 digit password, before the connection is really established.
also, if i remember correctly from my blueangel (which had a password bug with cooked roms), a hard reset wouldn't even be enough to unlock the phone again, because potential thieves could do that as well and had a brand new phone on their hands. so only flashing the device with another rom did the trick.
assuming that, as a reasonable windows mobile user, you create regular pim backups, either using pimbackup, MS myphone or outlook sync, you might be better off, just flashing the rom again, performing a hard reset and start over. after all, as of now, your phone is only a useless brick and being able to use such a great device again should be worth more than a few sms or the 90-120 minutes it takes you to flash the device and set it up again and install your apps.

Its the Window's built in security feature.
It seems as the activeSync works to update my Microsoft Outlook with information from my phone while connected to my PC. But Mymobiler doesn't connect to the phone.
I wouldn't even know where to start for flashing the rom - never done that, looks like I'm going to have to do some reading on the forum...

UPDATE: I did a hard reset on my phone and now after booting, it shows a screen alignment screen and I keep pressing on the screen where the marker is, each time the marker moves to the next location (center then each corner of the screen). After I finish with each location, the process starts all over again - it just keeps doing this.
Any idea what is wrong now???

if it just keeps starting over, the points you pressed were too far off the regular grid, so the device "doesn't believe it". you should have a look at your screen, whether somewhere there might be a tiny peace of dirt or an air bubble under the screenprotector or something like that. since the blackstone lacks multitouch, when it detects 2 display touches, the relative center of the 2 points pressed is the touch point it recognizes. say, you have dirt pressing your display in the top left, you are aligning the screen at the bottom right, it will determine the relative middle of the display as touched point.
so what i'm trying to say is:
either your screen has some hidden peace of dirt somewhere, which would mean, clean it thoroughly, OR your display is starting to fail due to a hardware defect, caused probably by the device's age and everyday wear and tear. in that case, have a look at ebay for the digitizer+lcd combo, download the blackstone service manual and exchange the display. also, in case you need to buy spare parts, be advised that the price for a used blackstone, depending on your location, might only be as high as 80-180$ (which makes some spare parts heavily overpriced in comparison to the price of the device itself).

Thanks again Chef Tony! I'll give that a try.

I was just looking at ebay for a digitizer+LCD combo and saw this but also saw a digitizer only which was much cheaper. Since my LCD screen appears to be fine (image on the screen visible), do I need the Combo, or will the digitizer only work (or is it much easier to install the combo, etc?) Since I've never done this, just wondering...

i believe there are a few other threads on this forum dealing with both the installation of the digitizer only and the combo. the problem appears to be that the lcd and the digitizer are glued together, which makes it very hard to separate your original unit and there is a risk of harming your lcd in the process, which makes the repair more expensive. personally i'd go for the combo for more convenience.

Thanks - that make sense. I'll look at getting a combo. I found the post with pics about replacing it on the forum and hopefully that does it for me. Thanks so much for all of your help!

Thanks Chef_Tony! Got the combo unit and installed it today - phone is back up and running! Thanks for all of your help!

Black screen and no functionality but want to pull data

Hi i dropped my phone and the screen is black. I know it still works because the fingerprint still vibrates and the pc still recognizes it via charging method. I have some important photos that i didn't have backed up and now wish to recover. Can somebody show me steps to get into mass storage ?

In general, you can. You'd need to have ADB enabled though. You'd use the ADB pull command.
If anything, are you on stock with stock display size? Do you have apps that keep a persistent notification?
If not, I'd say you could try this;
Basically get someone to match your setup. They'd install any apps that you use which use persistent notifications to exactly match your setup. If none, have them take a picture (with an actual camera or another phone) of their 6P with the notification shade pulled down while plugged into a computer. Then another picture after they click "Charging Only" to switch it to MTP. If you can unlock the phone with the fingerprint scanner, and start up top to pull down your shade, you should be able to follow visual queues to enable MTP instead of charge only mode. Then you could at least navigate the folders on the phone and drag and drop your pictures to PC.
Edit: Assuming your screen still responds to touch, but is just black. Didn't see it specified. It's worth a shot.

None, AFAIK.

God you people....if you have TWRP installed as recovery.....do this until it works right...timing is everything...hold the power button down(I know you won't know if/when it powers off) and hold down the volume up and power button when you think it powers up....volume up and power enters recovery directly, not bootloader....then you can connect to computer and transfer as twrp has adb enabled by default

No need to be so condescending. Especially since you offered OP a useless tip.
Why? As stated in their 1st post, their fingerprint scanner unlocks the phone. You can't have a fingerprint set without a pin, password or pattern. Since TWRP does not support fingerprint unlock, they would have to manually input their password for TWRP to access their data and have it show on a PC. As mentioned by OP above, the touch screen is non responsive. Meaning they cannot input their credentials to decrypt.
Edit: Just to confirm, I went to recovery and tried myself. Folders will not show up in file explorer on PC until TWRP is unlocked. ADB devices does show device ID as in recovery, but issuing ADB pull commands does not work. I pulled several folders and all I got was empty folders with no files. If they're encrypted (they said stock, so I'm just going to go ahead and assume they are encrypted) with password/pin/pattern (which we've already established is the case) this will not work.
@OP, I'm not sure of a way you'd be able to get into your pictures at present. Maybe someone with more technical knowledge could chime in, but as far as I can see you need to replace your screen. Either send it in to a repair shop, or DIY.
Here's a link for a new 6P screen (this is just the first link I found). Shop around yourself, see if you can find better prices & also be wary of reviews:

so i have used a usb-c hub with an hdmi port and usb port - then hook up phone to a monitor (not computer) and i had a pattern lock - it was really annoying as i had to guess where the dots were as the monitor doesnt show you where the dots are - but i used my mouse to unlock it - if you have a number lock it is easier to unlock - as you just makesure numlock is on then type in your passcode - once there you should be able to navigate round your phone using a mouse - turn on debugging and make sure you have the usb connection set to MTP (media transfer protocol) instead of charge only - id also take off all locking mechanisms to make it easier for yourself - then plug it in your pc and transfer all files across

Yotaphone 2 - Broken LCD screen - Can't pass Setup Wizard and use phone...

Hi,
I broke my LCD display a couple of months ago still, I managed to use the phone with the epaper display and eventually reinstall it without clearly writing down the exact procedure (with Lolipop)
Today, as my Marshmallow update freezed, I had to wipe all, thinking well I could easily find the steps to start the phone again.
The only problem remains that Setup Wizard wants us to use the LCD display, and I can't.
The last time I managed to use screen mirroring on Windows, with androidscreencast-0_3_1.jnlp, which is dicontinued.
To that extend, I allowed USB debugging (three lines to add) on system/build.prop and default.prop and copied a file from my computer (adbkeys.pub) to a certain folder in the device, to allow my PC to operate on the cellphone
But that last step doesn't work anymore.
I can see a dialog briefly popping up on the yotaphone, prompting me to allow the computer for debugging, but I can't click.
Droid Explorer tells me that this yotaphone is not allowed in $Vendor (or so on, I can't remember well).
So I managed to authorize the screen mirroring before, to start the phone, but I can't right now, although I found a new app, androidscreencast-0.0.10s-executable.jar.
I would have to copy adbkeys.pub to data/misc/adb/adb_keys, but as of today, that directory doesn't exist.
Can somebody please help me with that?
Thanks,

Hi,
I solved a similar situation by plugging a mouse to the phone using a usb to micro USB adapter (also called USB OTG adapter).

I've made it : the phone starts again.
If anyone is interested, I'll tell the trick for a broken front screen like mine.
Now I'm looking forward to make an image backup of it as it is very fresh if it can save me or others !
And I need advices for that?

Hi!!!
I have the sale problem
How did you bypass the wizzard???

hi. how do you bypass setup wizard? i had mine reset due to stuck. before im using only back screen. please help!

My front screen also stopped working all of a sudden without me doing anything. I was able to use the eInk so I did a factory reset. Now however I'm stuck since I can't boot the phone without a working front screen. I was wondering if a software issue stops the front screen from working and if there is a way to check/fix it.

$125 reward if you help me to turn on USB debugging mode on my Nexus 6P broken screen

Hello guys,
I have broken the screen of my Nexus 6P and I really want to save my data before moving to a new phone.
I've found several applications to control phone from PC, but all of them needs USB debugging mode enabled, which is unfortunately disabled on my phone.
I read here on the forum some method to enable USB debugging from PC via USB cable, but I'm not an expert and I can't do it.
My phone is locked by screen lock (PIN code, of course I know the code), and the phone is NOT rooted, OS is the original one (with all the updates installed.)
If any of you guys would be able turn on USB debugging on my phone without losing my data, I will be glad to reward his efforts by $125 and a HUGE "Thank you"! Money will be sent via PayPal, remote session could be done via TeamViewer.
I really hope someone of you can do it!
Thank you in advance!

How is the screen broken?
Is it just not responding to touch? Is the lcd shattered or dead black?

If you can see even a little of the screen, grab a usb-c OTG cable ( https://goo.gl/BzUKno ) and use a wired pc mouse to make all entries needed.

i have good news for you as other have said you need an otg cable i tested with this one https://www.amazon.com/gp/product/B01COOQIKU/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 and it worked with this mouse and keyboard combo https://www.amazon.com/gp/product/B005DKZTMG/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 im sure other will work but thats what i tested with once it is connected swiping up is a bit hard i was just trying to drag it all the way up at first but to get to the pin screen you will need to do it in a flicking up motion then just you the the number keys on the keyboard and unlock then the next best this is probably to try and cast the screen so your not blind if you cant and you get it unlocked these are the steps ...
1. unlock clicking and swiping mouse up then enter pin and hit enter.
2. down twice on keyboard and then enter to get to app drawer
3. type settings hit enter twice
4. down 11 times enter.
5. down 3 times enter.
6. down 13 times enter right once and enter.
usb debugging should be enabled that is for android 8.0
ps if you dont have developer mode enabled it will be different if so tell me ill count it out for you for that too.

For $125.....
For damn near the cost of the reward, you could get another screen/assembly and swap the guts, having a fully working device again....

If OEM unlocking is on / bootloader is unlocked, you can try flashing twrp recovery(after unlocking bootloader) and check if files show up on pc (I think MTP mode is on by default in twrp).

Perhaps trying this.

I'm afraid I'm not able to do what you described (I'm not an expert at all), that's why I need someone who will help me. Moreover I need not only the files but it would be optimal to get full access to the phone, first of all because I need to use google authenticator. That's why I need usb debugging mode to be turned on so badly.

If possible, I prefer to be able to turn on usb debugging mode because then I can get full control on my phone and control it from my laptop, not only getting able to save my files. I need it mostly because I need to use Google Authenticator on my phone.

1. I successfully unlocked the screen by typing my pin code, I can even hear the audio confirmation (ie. unlock sound). Fortunately I have to do it only once because after the first successfully unlock I can use the fingerprint reader to unlock the screen
2. Once the screen is unlocked, I hit twice the "down" button on the attached keyboard. I think something is going wrong here, because after the first "down" I can hear the audio confirmation (ie. keyboard sound), and after the second one I can't hear anything as if I stepped down on a list which has ended already. Any idea what do I do wrong?

Please see this thread here on Xda. It has the commands to enable usb debugging and also control a phone with broken screen. I seen your thread and thought this could help. Good luck & God bless.

Thanks a lot for your suggestion!
The thread you linked says I should enable usb debugging via recovery using this code:
Code:
Adb shell
echo "persist.service.adb.enable=1" >>/system/build.prop
echo "persist.service.debuggable=1" >>/system/build.prop
echo "persist.sys.usb.config=mass_storage,adb" >>/system/build.prop"
reboot
Unfortunately I have no idea how to do that.
My $125 reward is still available for anyone who could help me with that via TeamViewer (or any other way.)

How to recover data after display stopped working?

Hehy there,
unfortunately the screen on my mi9t stopped displaying. Really weird. While I was using it, the screen started flashing, just to turn black and never wake up again. No fall or water involved. The phone still seems to work fine, and even touch seems to work, but no display.
I opened up the phone to see if the connector got loose, but everything is well in place.
Now my problem ist, that I can not access the phone anymore. All my files and things are still on there but unreachable.
Here are the facts:
- no display
- bootloader is locked
- usb debugging is enabled, but my pc is not authorized
- I can blindly get into fastboot and to the lockscreen
- I am not able to blindly unlock the device
Easiest option would obvoulsy be to exchange the display, but unfortunately I can not get on here (South Africa) and shipping would take a month.
My favourite aproach so far was to mirror the screen via Vizor, but unfortunately it needs to install the according app on the device, which it can not while the device is locked.
Does someone here know how to recover the data?
Thanks
and a happy new year to everyone!

When I experimented, I was able to unlock my two SIM cards and Android by adb (replace xxxx by your PINs)
However, phone was rooted and shell was given the root grant:
adb wait-for-device devices
adb shell
su
input text xxxx
input keyevent 66
input text xxxx
input keyevent 66
input touchscreen swipe 930 880 930 380
input text xxxx
exit
exit

try fastboot apk
Mirror screen to pc with vyzor. You have usb debugging turned on, so it's worth a try.
If touch doesn't work, use usb otg adapter to plug keyboard or mouse
There's no other option.

Thank your for the idea! Unfortunately it does not work in the unrooted phone. I suspect that's only because I can't the adb connection to my pv authorized.
I tried this on an unrooted lineage os 17, which I have on my old Mix2, and there it works like a charm.

Thanks for the advice. I think i tried everything to get the apk installed, but I can not do anything through adb since even though debugging is activated, the connection to my pc is not authorized.
I guess I have to wait for the replacement screen.

Any water exposure? Ever?
May not be the screen; a mobo failure is just as likely even more so especially if they use no lead solder paste.
Maybe a loose or bad connector/cable if you get real lucky... and find it.
