Navigate Setup Screens by OTG USB Keyboard - MeMO Pad 7 Q&A, Help & Troubleshooting

I just picked up a dirt cheap ME176C on eBay with allegedly a broken digitiser [The screen works, but doesn't respond to touch]. Naturally the previous owner has done a factory reset, so it's stuck on the first setup screen [Choose Language]. Before I decide whether or not it's worth buying a new digitiser for the MemoPad, I want to try and get USB debugging turned on so I can ADB Shell in and have a poke around at the various sensor logs and see if everything else looks OK.
So, the challenge is to navigate through the setup screens without using the touchscreen.
I've got a USB OTG lead, so I've tried plugging a mouse in, but no joy [no cursor appeared]. Then I tried with a USB keyboard and found that, by hitting the Return key, I can pop-up the Language selection menu and then select a language using the keyboard arrow keys. However, I can't find a key [or key combo] that will then change focus to the arrow to take me to the next setup screen.
Does anyone even know if what I'm trying to do is possible? I was quite hopeful, when I hit the Return key on my USB keyboard and saw the Language selector menu pop-up, but there doesn't seem to be any way to move focus to the next UI element on that screen.

[Q] Display broken...need to turn on USB debugging

Just like the title says. I was in a car accident a few days ago and my phone got thrown around and the amoled is cracked. I turned off the option to turn on usb debugging when connected and now I need to find a way to get it turned on so that I can control my phone through the pc. Any ideas?
You'll need to navigate by going with where it is approximately on the screen. Then to verify that it's connected just adb devices if nothing returns try it again. Here are some pics to show you where to press on the screen (red arrows show where).
NOTE: this starts at the settings screen to get there just press menu then the bottom right corner.
Thank you for the screens. I guess I should have mentioned that I'm running CM7, so I might have a little trouble with the first step, adjusting for the extra cm settings and adw settings. Thanks again.
here's the Settings for ADW EX.
hopefully its in the same spot.

Touch screen defect - map Back key to hardware keyboard?

My trusty Milestone's touch screen stopped working (defect ribbon cable maybe - it wasn't exposed to anything unusual).
Since I'm only using it as a bluetooth hotspot I don't need the touch screen that badly since it's possible to navigate most menus using the D-Pad.
BUT it's not possible to go back or to the home screen (or I haven't found out how) so here's what I would like to do:
Map the Back (and Home key maybe) to the hardware keyboard.
I tried mapping Back to the physical search key in /system/usr/keylayout/qwerty.kl
Code:
key 217 BACK WAKE_DROPPED
But it shows no effect :crying:
Can anyone provide help?

Z3 Play users - I need your help

Hello guys, the other day I dropped my loved phone and the screen broke. No big deal I thought - just order a new display assembly and I'll be fine. Sadly the internal display connector on the logic board happened to break too, infact I tried two displays but none worked, then I noticed some misaligined pins on the ribbon connector - logic board side.
I have some very important stuff on this phone that I absolutely need to recover. To do so, I need to enable USB debugging and developer options in settings. I can do that with an external USB keyboard connected through USB-OTG, but the best I can do blindly is inserting the lockscreen password, then I can use WIN + N to open the notification tray but I have no idea what to press next. If anybody happens to have a z3 play, an USB keyboard and some spare time, please write me the keys to press to reach first the settings menu and then build number/developer options. I suggest doing the steps in offline mode so that the keys are 100% the same as mine, also I'm using the latest version (Pie) on the latest security patch.
If you could help I'd really appreciate

Can't get any data out of my phone after screen problem. Please Help

Please. Please help me out to get my files from my damaged screen P20 Pro
To be honest I'm starting to hate those HUAWEIS... It have done the same thing twice in a row, this time I was more prepared when last time but still same thing happening, I cannot connect it to PC or even TV thats means I can't get anything out of it :crying:
This time I am 100% sure I had USB Debugging enabled, also HiSuite is also was installed on my phone I just didn't use it. Now when I really need it connect it to my PC it doesn't work! No matter what I do... That is super annoying as they made very simple thing, super complicated and annoying...
- HiSuite doesn't find my phone and keeps popping messages that I need to enable USB Debugging even when its already enabled.. It also gives me message sometimes that I need to install HiSuite on my phone as well but its already installed.. I had checked it trough my PC via Google Play and it says its already installed. Totally useless app if you having screen problems.. I also tried “dr.phone” which cannot find my phone too and few other cant remember the names but unsuccessfully too
The worst thing is that before damaging my screen it was able to access files I was also able to use my Type C HDMI adapter without any problems on TV and Projector but now it doesn't work too... What the hell? WTF is wrong with that thing? The only reason I can think of is that before connecting it to PC or TV I have to unlock my phone first for some stupid Huawei safety reasons and now when I cannot do it because of my screen problem it doesn't connect to anything? If I am right, is there is any way go around that, take off the screen lock without resetting whole device??
On top of all this super annoying bull**** I have found on another Android device which Im using now that all the contacts I saved with my P20 Pro wasn't actually saved into my google contacts at all and all my new contacts for over half year are gone too on all other devices, for some stupid reason it didn't saved them to my google acc even when I am always saving it that way. I never had such a problems with any other devices in the past and I am android user over 7 years.. This phone can get really annoying in some situations, it does what it wants
Can anyone help me out on this one? That would be Amazing :good:
Use a kB to type your pin unless the screen works..
Then copy out..
If you can't turn on usb / hdmi then you'll never guess it..
kB over usb c is your best bet mate..
End of..
Hard times man.
OR....
You get the repair guy to do it whilst you're there lol..job done.
which part of your screen is damaged? the touch or the display or both? Not able to do something you really want might be really frustrating. If I were you, I'd do this way.
I'd plug-in a USB-C hub ( with USB ports for keyboard/ mouse combo, another USB port for storage device, and a HDMI output). Plug-in my flash drive, mouse/ kb, and the monitor (or TV).
the phone will instantly switch to the desktop mode and you will be able to use the keyboard/ mouse and able to copy the files to the flash drive you plugged in.
Maybe you'll need one of those USB-C adapter with power pass-through.

Hey! I have a similar condition with OP. Thing is, I have a USB-C to HDMI connector, and I tried connected it to my monitor. But it's not automatically switch to Desktop mode, instead my phone screen is displayed in my monitor. The thing is, I have enabled password requirement after reboot, and I can't type the password even with a keyboard or a mouse (I was guessing the numpad pattern hundred times, and just click the areas).
So here's the review:
1. Screen cracked
2. No display
3. Touchscreen not working
4. ROM EMUI 8.1
5. Bootloader LOCK (No root, no custom recovery)
6. USB Debugging disabled
7. Password authentication after restart is enabled
8. Can display the screen on my monitor via USB-C to HDMI
9. Mouse and keyboard seems to responding, but not work when typing my password, the screen just freeze when I tried to do that and nothing happen
10. HiSuite acknowledge my device but can't do anything because I haven't allow USB debugging connections.
11. Data not sync to Huawei Cloud
I will not repair the screen because it's $250 exc. labor cost in my country, I preferred save my money to bought another phone. I want to access my data on the phone, Any suggestion?

Thank you for you answer mate. I ordered adapter and the keyboard but some reason it still didn't do the trick. But it does work on other devices straight away. Strange... maybe again some stupid huawei security thing.. I will try dock option, its my last chance :crying:

Thanks for your respond :good: Im not sure about touch screen, I dont thing its working but I can't fully check that at the moment, as for screen its completely dark. You think so? I just ordered type c dock, hope it will do the trick, as keyboard alone with adapter doesn't do the trick :crying: so dock is probably my last chance. Thanks for the advice, I hope it will work

You may need to select something on screen to allow it. Does video come up? Or do any peripherals work?
Are you powering the hub?
Wired or wireless KBM
My wireless one in work, didn't work for me, whereas my wired ones did.
Are you on emui or a custom ROM?
Tbh custom ROMs would probably have more luck from experience.
Did you alter the default usb mode from charging to anything else?
That may also be causing an issue..
Does any input work at all on the phone ? Could you try by measuring input on an identical device then touch the exact part of the screen to unlock it??
I've been here before, but it is starting to look like a lost cause pal.

It looks like this phone does everything he can to keep my data locked :laugh: I connected it successfully via Type C Hub (Good recommendation btw :good::good For some reason my old type c hdmi adapter just doesn't work after screen crash
So finally I have got my hdmi signal back, I can see my lock screen now which is a very good sign, mouse and keyboard works too but now I got another super silly problem which now makes me look like this peace of **** is laughing out of me
I tried connecting my phone to TV and Projector, I can see my lock screen fine but once I push Space on my keyboard or scroll the screen with my mouse to unlock the screen I lose my screen connection straight away...
I tried entering my code on blank screen, pushing enter etc... but nothing happens or if it does my screen is completely dark and I can see nothing, I push on/off button twice and I get back my screen connection back with my lock screen again asking for same code Seriously wtf?
It looks like that moment which lets you type the password in can't be transmitter on my tv/projector for lets say some resolution issues... just guessing but my code entering on blank screen doesn't look like is doing anything either
I have an official Rom without any tweaks

Disconnect either the mouse or the kB. Might be too much power. Are you powering it?? Change cable. Change TV.
No it doesn't have external power source. My current type c hub, doesn't have this option. Only Hdmi, 2x Usb 3 and sd & micro usd slots. Is there is anyway to add it now externally?
I have tried it already with single kb or mouse. Even connecting my wireless kb just with usb type c adapter with no luck. Once I come back home today I will give a try with only Wired Keyboard connected. Haven't tried that yet

it's better to use USB-C hub with power delivery (i.e, u can plug in your charger to the hub).
I also tried your scenario at home last night. I plug-in my keyboard, mouse and HDMI cable to the hub, then i plug-in the hub to my phone while the phone is locked. first, there is nothing. No signal.
Then i press power button on the phone, I then saw the mirror of phone display on the monitor.
When swipe the mouse to reveal the unlock screen, yes, the monitor suddenly lost the signal, but just continue typing in the password correctly. The phone will be unlocked and u will get back the HDMI signal on the monitor.
then pull down the notification panel and activate the EMUI desktop mode. That's it.

Thank for your respond. It's sounds simple and obvious but for some reason I can't get through that bit for some reason, I even started thinking if google could changed my password but thats very unlikely but its acting as it is, as I don't know how can I type my password so many times and it still wont pick it up
I will give another good try today once I get back home, it does look like I tried that already but will give another try. The thing that you lose signal at code bit as well tells me that it not just happening for me and that my kb and mouse should be still working at that time as i though I could be getting full disconnection at that time.
Do you need to click Enter to confirm typed code in? O does it unlocks straight away after correct code is entered? Tried both still
Hi did you manage to get this sorted? I'm experiencing exactly the same now. Tia
Same issue

Did you manage to get anywhere? In the same boat. Can get lock screen up using HDMI adapter, but when I unlock, the screen goes black and the monitor says no longer receiving signal and goes into standby mode.
I have the same problem - even with a active USB-C hub...

OK. This is how I got my P20 Pro to work.
- I used a generic USB-C to HDMI Adapter. Mine was the Baseus UCN3277.
- Screen Broke completely
- Touch not working
- Fingerprint not working
I just used a wired cheap HP USB Keyboard connected to the USB-Adapter. Using a wired Mouse made it not work for me. I think this draws to much power.
Connecting power to the USB-Adapter also made it not work. (This might be just for this Adapter)
Remove all Sim cards! I had one in the second slot. This made it not work.
This is how it works for me:
1. Connect the USB-Adapter to the Phone and the TV
2. Press the Power button on the phone -> Screen appears on the Monitor
3. Press Space -> Monitor goes black (seems to be some security feature from huawei)
4. Despite the black monitor, type the Password on the Keyboard (I did not use the numpad)
5. If the Password is correct, your in at this point
I used teamviewer to control the phone, so that I could confirm the RSA Fingerprint message, when I want to use adb on the PC.
Hope this helps for people with the same problem.
I am having unfortunatly the same problem here. I did managed to get my phone's screen on my monitor for only seconds (sometimes scretched all the way to 16:9 aspect ratio), but often just black screen or a grey screen with the time and a unlock icon beneath it.
Strange enough it all works right away on my newer Samsung. I tried different mouses and HDMI cables. Going to try a different monitor or TV aswell. Anyone other suggestions?

i have usb hub with hdmi and power delivery + extra usb ports for mouse/keyboard...
can't get pass the gray lockscreen with clock and lock icon - when i press space on the keyboard, talkback says it requres a pattern code which i have to guess where to draw (or so i think)...
can pattern be entered via keyboard's numpad? (like a phone numpad where 1 is a top left corner and 9 in bottom right corner)
Whoa, thanks for this thread. Same problem here, but with my P30.
I only used my mouse before, but with my Sidewinder keyboard it worked. I had to touch my phone, then put in my password and now i have acess to my old phone and safe all the photos. THANK YOU!!!
I used this hub and connected it to a normal usb c power supply https://www.amazon.de/gp/product/B07RQLF6M8/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

were you able to put in the password with your keyboard or did you use your phone. My screen is broken and unusable so I'd have to guess the password?
I have the same problem with my Mate 20X. the phone feed to the monitor freezes or just goes blank as soon I swipe/unlock the phone to put in my password. I tried different combinations with my USB-C hub (powered, not powered, only mouse, only keyboard, both) but it still doesn't work.

Best way to copy a system app on a locked tablet?

I have a tablet, its not a Tab it is a generic tablet but running a version of AOSP on android 4. It came with a smart home device I use to control it. The problem is the tablet is designed to work exclusively with the home appliance (in this case an air purifier) and nothing else. It sits in a case and has no touch screen buttons when removed from it. I included pics and specs of the tablet. The tablet has been completely unlocked by the manufacturer however the system only boots into the program used for the air purifier. When it starts you can see the Linux symbol in the top left of the black screen until the android logo shows up, then it goes into the full screen program and that's it. You cant get to any options or settings or anything. The best I can do is bring up the keyboard and get into "keyboard settings" and even then I get stuck because I cannot hit any back buttons and there is no on screen controls. So you have to reset the tablet to get out. I am trying to take the application used to control the purifier from the tablet and put it on my PC so I can install it on other tablets and phones. However I cannot do ADB because I cannot access dev options in settings. When I connect to the PC it sees the "flash" drive but it's empty. I was hoping someone may be familiar with a way to connect to the tablet and access the root files when you cant enable USB debugging or how to enable it using older AOSP. Any help or insight is appreciated.
