[Q] New Chinese smartphone has me stuck at lockscreen - Android Q&A, Help & Troubleshooting

I bought a Chinese smartphone from DX.com. I wasn't expecting great quality, but I was expecting it to at least give me a workable system out of the box. Instead, upon first powerup it gives me a lock screen - and I'm not told what the lock key is. I requested help on DX's forum, but as they don't themselves manufacture it I expect the answer to take a long time to arrive, if it ever does.
By powering it up with various buttons pressed I've managed to get it to boot to what I'm assuming is some kind of debug/recovery menu. It's interesting that it isn't the usual Android recovery, but it's something running within the system itself.
In this mode the lockscreen is disabled, but so is most of the operating system. I did manage to get to the settings/language menu, but when I access it I get this error.
I tried accessing the developer options in the hope of enabling debugging and accessing the filesystem via ADB, but the whole submenu is inaccessible in this weird testing mode.
As for the obvious idea - accessing the security menu and disabling the lockscreen - even in this mode it still wants the previous combination before it'll let me disable it.
The debug menu itself. I tried accessing a few options at random, but I get a lot of text I can't understand and large buttons with red/green colouring that look menacing. What little is written in Latin alphabet (stuff like RECALIBRATION) makes me think I could easily screw the phone up by experimenting with the various options without knowing what I'm actually doing. In general it seems like a hardware test app, though; one of the options I did dare test makes colors appear if you push the non-touchscreen buttons. I'm not sure anything in this can be used to bypass anything.
I tried posting to the /r/chinese subreddit to see if they can make sense of those menus. Is there anything I can do in the meantime? I don't know, does Android 4.3.3 have a default combination for that accursed lock screen? Getting to the default Android recovery and doing a factory wipe would probably solve the problem, but so far I've only managed to get the weird testing mode by booting with buttons pressed.

After an immense driver headache, I have managed to gain ADB access to the filesystem. However, "adb reboot recovery" doesn't show a recovery menu - I get the Android animation with the rotating whatsitsname, then a red exclamation mark.
Edit: I have changed the language to English via ADB. The lockscreen is still stubbornly in place.

Starting phone from standy in landscape mode

So I have a habit of sliding the phone open and then pressing the hardware messaging key, and no matter what, it never seems to work. I press the button, and Ill see the today screen, but no messaging window. I have to slide it back closed and open again and everything sorts itself out.
I've tried looking, but haven't seen anyone complain about this particular problem. Anyone else fret about this? any solutions?
no one has this problem?

I find my X01HT in landscape mode when i wake him um with the "on" button, and have to wait for it to "think" a litle bit to obey me, while that, if I try to push any command he will go crazy and the image will stay locked in the last scene and will not get actualized... Kind of annoying thing, using black Satin... But i'll try schaps now to see if that goes away...

Im on WM5.
Vijay, I don't want to disable orientation permanently. Just sometimes, I want to start messaging, so in stanby mode itself, ill open and start it up. thats what confuses the 8525, thats all. I have to close the phone, and then slide it open again for it to regain consciousness!
Its no biggie, but i was just wondering if any1 else had a similar issue.
FINALLY... WHAT YOU HAVE ALL BEEN WAITING FOR

I've come to notice that no one REALLY knew how to fully disable screen rotation on WM devices.
Some offered 3rd party apps to get the job done, some only knew how to disable automatic rotation, but when the device went into standby and woke up again - the screen rotated back. So that didnt really work.
So if you're as desperate as i was about screen rotation,
this is what you need to do:
1. Get dotfred's free taskmanager HERE, and run it.
2. Go to "Devices" tab, and look for "MIS1:" device (oem_misc.dll)
3. Long-Tap on it, and tap on "Stop"
4. Long-Tap on it again, and now choose "Set Manual"
5. Go to "Notifications" tab, and look for "Notifications\NamedEvents\VCPowerWakeupEvent"
6. Tap on it to make it selected
7. Disable it
(In dotfred's taskmanager, there should be a button for disabling it, but for some reason some devices couldn't see the button icons, although the buttons are still clickable. Under the notifications list there is an empty light-blue line - the buttons are there, eventough you can't see them.
The disable buttons is somewhere i the middle of that light-blue line, just tap the center until a message box popps up and asks if you'd like to disable this notification - Tap on yes.)​All those steps are a one time deal - they stick even after an SR.
This has been tested on htc universal and works great.
The screen will keep its orientation even if you flip your screen, take out your built in keyboard, or turn the device off and back on.
The only time your screen will revert back to the original orientation is when you soft reset your device.
Hope this helps

[Q] Sleep mode and Help info - Where are you?

Is there a way in VEGAn-TAB 7 to select "Sleep" mode from the menu that pops up when you disengage (now shows "Power Down" and "Reboot" among other selections. but no "Sleep" selection). Also, is there a "Help" capability for Android 2.3.3 or the VEGAn-TAB 7, to give us new-to-Android users some assistance to understand how to use or work with this Android system and this ROM? All this is my first venture into Android land, and even though I've learned a lot by going from screen to screen and menu to menu, I could really use some additional help info along the way. For example, some of the icons and what they are for is unclear. In the menu, I understood the icon for WiFi and Volume, but not the other icons that are displayed (the volume icon intechanges with another unknown icon). Thanks for any help on this.
This is especially frustrating to me because I'm an old (now closing in on 76 years) technical writer who wrote PC software and hardware manuals for close to 25 years. But that's another story.

[Q] (Code question) Need to figure out a way for my widget to update it's icon.

Hey all,
Forgive me if I need to post this elsewhere but the searches I have done have come up empty.
I'm pretty new to Java and Android development. So I'm sure this is an easy fix. But I could use some help.
The short version is I need to figure out a way for my widget to monitor the silent mode status. And would like to know what monitor's the home screen usage in android system.
The long version is this. The widget is pretty simple it just toggles the silent mode. (Hey we all have to start somewhere.) The problem is it's designed to update the icon to reflect the silent mode status, but the code triggers through a click action. See the problem? Yep silent mode can be toggled in many different ways. Thus what I need is an efficient way to monitor the silent mode status. My current idea is to have it run a simple check whenever the "home" or "back" buttons are pressed/whenever the home screen displays.
Problem is I don't know what SystemService checks that. I'm not really looking for an "ok plug this code into..." I want to learn. I'm looking for what I need to call in so I can monitor when the user returns to the home screen. Or if anyone has another more simple fix I'm all ears.

[Q] Lockscreen-Problem with GT-i9100

Hi everyone,
first of all I want to say I'm new to xda-developers and also I couldn't find the GT-i9100 in the list for new posts so maybe this isn't the right place for this thread . in this case, sorry, maybe someone has a hint where to post it then
So here's my problem:
My phone won't enter lockscreen. Around three days ago it started to just resume back where I had left once I press the home button (the round one in the middle) without asking me for my PIN.
I had gotten the phone used, so I did a factory reset and afterthat I installed cyanogenmod, thus rooting it, but not manually - I guess the installer did that for me.
First I had a pattern as screenlock but after applying the full-disk-encryption it would only let me choose between PIN and passoword so I set up a PIN.
Then it just started to skip the lockscreen when waking up. I get still asked the lockscreen-PIN when booting, then the SIM-PIN, then the lockscreen-PIN again, then it boots, but when the screen turns black i can always resume by pressing the home button. Also, the power button just makes the screen black, but also without ever locking it...
What I tried so far:
Settings / Lock Screen / Screen Security / Automatically Lock set to 5s
Settings / Lock Screen / Screen Security / Power button instantly locks checked
Settings / Lock Screen - Widget Pager unchecked (i read it somewhere, can't find the exact source anymore)
http://forum.xda-developers.com/galaxy-s2/help/lock-screen-home-button-fixed-t1506317 --> also tried this method, also rebooted after applying every of these changes listed above
I hope this is not too much of a stupid problem because I missed something really obvious - although that would be nice
Anyways, i would really appreciate it if anyone knew a solution to this.
After all, full disk encryption isn't exactly useful if your phone is always unlocked...
Thanks in advance everyone!

Rescuing from a faulty/malicious app black fullscreen takeover

Hello. So strange. A friend's HTC U11 Android phone boots up normally and just as the UI starts to load in, the entire screen is taken over by nothing but black. Tapping on the screen unveils a white dot where the tap is occurring (I'm wondering if they messed with Developer options and caused this?). The hard buttons still work. It operates in the background. Swiping down from the top edge doesn't work. Opening the task viewer doesn't work -- you can't do anything. Pressing and holding the power button does bring up the restart/power off pop-up. Gestures work (tried three-point multi-touch swipe downwards and a permissions request for HTC Connect popped up). These pop-ups happen over the black fullscreen. Other than those, nothing works.
For the split second that it loads the UI upon boot-up, I've tried quickly swiping down from the top and tapping on the Settings gear icon, however even though it goes into Settings the black fullscreen takes over just the same.
Tried wiping cache. Tried booting under "Safe Mode" -- nothing helps.
Now, the phone is not rooted, and it's set up with encrypted unlock at boot-up, so that makes things even trickier. Perhaps there's a way to install some sort of app that clears startup apps/services from Google Play remotely using a desktop computer on the account? Or it won't work until the app is first opened on the phone right? Maybe TeamViewer Mobile somehow and see if the phone's screen shows up on the connecting PC?
Tried plugging in a USB keyboard/mouse. I see the mouse cursor move around on-screen. Tried different keyboard shortcut combinations and nothing seemed to work. Any ideas in terms of keyboard shortcuts I should try?
Any ideas on how to salvage the data without losing it by rooting the bootloader? It won't respond to ADB. HTC Sync Manager doesn't see it either.
