[Q] Controlling Nexus 4 on the PC after breaking screen, possible?

Hey guys,
Haven't been here for a while. Okay, so I have a bit of a dilemma and every solution I've found requires something I just can't do. Here's the situation: my screen is broken, it has a lock screen, not in developer's mode, not unlocked.
This means:
I won't be able to transfer my files over, as I have to get past the lock screen
I can only install applications from Play store on my computer, but can't launch them
No use for any method that requires phone to be rooted
Can't even activate any USB options to transfer files some other way
Still need to be able to control it to create backups and such of important SMS messages, get files off
Does anyone have any suggestions at all? I don't want to have to resort to replacing the screen, as that'll end up costing me enough time and money where it's more cost-effective to purchase a new phone; however, I really need what's on my phone as soon as possible. Thanks in advance.

I think I have a solution for you: http://forum.xda-developers.com/showthread.php?t=2177440 Specifically, you'll want to read this post:

So typically, just as I fill my claim to repair my nexus my wife drops her, smashing the screen even more than I did so she has absolutely no use of her screen. I went through the process again and though I'd post it in a more simple fashion.
1. Reset Nexus into recovery mode (power & volume down)
2. Connect to PC via USB. Install the USB driver from the SDK so that it appears as an ADB device
3. Fire up the updated toolkit. You should see the nexus as a fast boot device
4. Unlock bootloader
5. Using option 10 on the toolkit load up CWM on the phone. This gives you ADB access so can you pull files off the device via ADB although I could access the SD card through programs like Droid explorer.
6. If you want to carry on further and get into Android properly, you'll need to wipe the cache from within CWM
7. Reboot and hold down the volume key to get back into recovery
8. In the toolkit select root options (option 4) and load temporary image (6) If it hangs on the google or nexus logo you've not wiped the cache.
9. With this second phone I couldn't access it through droid explorer as it was popping up as an MTP device but I could pull the files via command prompt or through the toolkit
10. If you have any use of the touchscreen at all you can run the following command which will then mean that any touch will unlock the device
adb shell rm /data/system/gesture.key​11. You can activate bluetooth via adb if you have a mouse or keyboard available but you will need to be able to press okay on the screen
12. Any changes you make in the unstable android image such as lockscreen, bluetooth, enabling debugging, etc will remain in place when you restart the device.
13. You can relock the bootloader if you wish via the toolkit. You just need to be in recovery mode first.
Hope this simplifies the process

In the future, always enable USB debugging in case of incidents like this. You can then use ADB commands to do a heck of a lot of things. Of course, it does make your phone data vulnerable if it gets stolen, but I'm willing to take the risk, plus 10 wrong PIN tries = reset anyway.

hi, what does this mean?
2. Install the USB driver from the SDK so that it appears as an ADB device

1. It means that if you have the SDK Manager installed on your computer, somewhere between the last packages at the bottom of the list, you'll see "android drivers" (or something similar). With those drivers, your device will show up in "Device manager"(the Windows' one) as an adb device.
2. But if you don't want to get the SDK Manager and be quicker, you can download only those drivers, directly from the "Google developers" page and install them manually by going to "Device manager", right clicking on the Nexus 4 (it will appear with a yellow triangle on it, maybe), then "Update driver", "...BROWSE computer...", then click again on "Browse", then go to where the drivers have been downloaded and select the entire folder by highlighting it and clicking ok (or something). The folder with the driver would look like this "latest_usb_driver_windows" and inside you'll see another folder called "usb_drivers". That's what you need to select and install.
So that's what you need to do to make your phone appear as an adb device in "Device manager". And, of course, adb let's you do a lot of stuff to your phone through your computer, but probably you already knew that.

[Q] Enabling USB Debugging in ROM Over USB on a rooted, unlocked, running CWR

Hey guys. My phone slipped out my pocket and the digitizer is broken. My phone is rooted, the boot loader is unlocked, and I have it recognised as an ADB Recovery device. I want to enable USB Debugging so I can use androidscreencast to use my phone over my PC so I can set it up to push notifications to my computer and to my pebble(smart watch).
How can I do this. Most of the threads I have found just flat out don't work or stop because of some sort of restriction due to the phone being still locked.

It looks like you need to run some commands in a terminal emulator on your phone. Which in your case is going to be impossible. Why don't you just use adb pull to pull the data off your sdcard?

Don't need any of the stuff - I could just boot in and take it over USB. All I need is to enable USB Debugging to send touch commands in place of my touch screen. Once I have that my pebble can let me use my phone outside of the house and I can send notifications to my PC too.

Bump!
Bump!

Anyone? I can't get a new phone for a while.

The biggest Problem ist the Drivers "FOR ALL"problems
You must have all Drivers for it

How to access Nexus 4 through PC, bootloader locked and not rooted.

I have the following problem. My Nexus 4's touch is broken, it can show stuff though. I need to run an app (the battle.net authenticator, otherwise I can't log in) through access from my PC, but there are some problems. It is not rooted, its bootleader is locked and everything is stock. I do have USB debugging enabled though. Also I can't do adb commands because this is a new PC and I haven't authorised it (it shows up as unauthorised on adb devices).
After a long series of experiments and a lot of googling, I found a combination of 2 programs ([email protected] and Android Control) to do what I want, and do some stuff when on Recovery Mode to activate the adb thing through cmd (most of those in this site), but my PC can't seem to even see that a device is connected when I am in Recovery Mode. I have tried reinstalling the drivers a couple of times but nothing seems to work.
Does anyone have any ideas?

As far as connecting to the PC is concerned have you tried another PC or USB cable? And since that's a battle.net authenticator you can contact their support, either via web ticket or phone (if you live in the supported countries) and after they confirm it's really yours account, they'll remove the authenticator for you.

I can see the phone just fine everywhere else, just not in recovery, so no I didn't try that. And I have tried using their support but I was in a pretty special situation for some reason and they couldn't help, but I fixed my problem. I had saved my restoration code for my authenticator ages ago and I didn't remember. Thanks for trying to help out though

Note 4 locked without USB debugging enabied (fngerprnt / bckup pword not recognised)

Hi
I have a Galaxy Note 4 (SM-N910G) and don’t normally muck around with the system. I have limited experience with Android.
My phone is locked (with important data stored in it)– a couple of days ago (presumably after a system upgrade) it suddenly would not recognise my fingerprint nor backup password.
I tried unlocking the phone using Android Device Manager but although I could get my phone to ring or display text, I could not change the password after locking the phone.
I called Google who said that Android Device Manager only works on earlier Android Versions - ?4 and below and most likely my phone would be running Marshmellow.
I called Samsung who said my only option is to restore to factory settings.
I wanted to use ADB
(to enter: adb shell
cd data/system
su
rm *.key) and downloaded it and tried to use it from the c:\ prompt but I don’t have USB debugging enabled. No device was recognised when running ADB.
I had not registered for a Samsung account so I could not use Find My Mobile.
I tried to apply an update via external storage in recovery mode (I downloaded files such as Lockscreen_Security_bypassV1.1.zip or Pattern-Password-disable.zip) but unfortunately when I tried to apply them, it came up with E:footer is wrong, E: signature verification is required.
(I also tried “Android Multi Tools”).
I do not have CMN recovery loaded nor Aroma+File+Manager
My question is: should I try and use Odin (have downloaded odin3_v3.11.2.zip) and TWRP to try and enable USB debugging or try to disable footer/signature verification??
Any other suggestions to try and unlock my phone???
At the minimum this has been an education!
Thank you for your help!

How to unlock any Huawei Bootloader after removal of unlock page including Mate SE

Hello All!
I was disappointed when I received my Huawei Mate SE BND-L34 (USA) 2 days ago that I could not unlock the bootloader because Huawei removed the unlock page from their website. Even after talking to support via live chat and email I could not get any help from them. So I decided to do my own research.
DISCLAIMER: THIS WILL WIPE YOUR DEVICE! THIS INCLUDES INTERNAL STORAGE! I am not responsible for any lost data or bricked devices!
Getting your Unlock Code:
1. First you need to go to https://www.dc-unlocker.com/ and register for an account. Do not download their software!
2. Instead download the software at https://hcu-client.com/
3. Install drivers via HiSuite if you have not.
4. View the supported devices page. Now the Mate SE is not listed as a supported device but it did work for my device (Mate SE).
5. Make sure your drivers are installed via HiSuite.
6. Now go into https://www.dc-unlocker.com/buy and buy 4 credits. This is needed for the software. Cost is 4 EUR ($5)
7. Launch HCU-Client and connect your phone.
8. Open the dialer on your phone and enter *#*#2846579#*#* select “Background settings”, “USB ports settings”, “Manufacture mode”.
9. Now in HCU Client log into your account (Check your Email for info) click Read Phone Info.
10. Go to Unlock tab and choose Read Bootloader code. It says it will wipe your device but mine did not get wiped until I unlocked my phone. This will take a couple of minutes. Watch the right terminal window. It should spit out your code.
Using your Unlock Code:
1. Turn off your phone, Boot your device into Fastboot mode with Vol down and power button.
2. CD to where you downloaded ADB/Fastboot Tools
Run these commands when inside ADB tools directory
a) fastboot devices. (your device should bee listed. If not reinstall drivers/reboot)
b) fastboot oem get-bootinfo (just to confirm everything is detected correctly
c) fastboot oem unlock <your_unlock_code>
3. Acknowledge the prompt on your phone. Device will be WIPED!
4. Once the wipe finishes it will take several minutes for phone to boot up. Do not panic. Once you See Huawei logo you are OK!
To root your Mate SE and Install TWRP follow this guide: http://www.desinerd.co.in/how-to-huawei-mate-se-root-twrp-recovery/
Do not use the Magisk Zip in that post. Instead grab it from here: https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445

The tool is safe. It's a false positive. If you are unsure Go read the HCU-Client forums.
Its your decision but I haven't noticed any ill effects. You can always run it in a VM.

Ok. Thanks

Stupid program won't run on my computer. Saw someone else on the dc-unlocker forums with the same problem. They linked a version to download but the link is dead now. I think this phone really wants to be returned.

You can try DC-locker instead of HCU-Client. I just find HCU easier to use.
Are u on Windows 10? If not make sure you have latest. NET Framework installed. Try running in compatibility mode.

Yes, Win 10. DC-unlocker link in the Android app shows 7x BND-L34 as compatible but it's not in the drop-down box of the Windows app and doesn't get autodetected .

Yea only thing I can think of is make sure latest .Net framework is installed and latest Visual C. Maybe try compatibility mode

The DC-unlocker problems were my fault. After getting the drivers right, it detected my phone and pulled the unlock code.

Logged into this account for the first time in YEARS just to say thanks a lot for this. I was pretty gutted when I found that Huawei removed their Unlock link and refused to give codes to anyone even via support emails.
I was super hesitant to try this though, I'll admit. Spending money on what (to me) looked like a shady site was the biggest red flag. But decided to bite the bullet and do it.
The only issue I had was that my phone DID get shut down after the bootloader code was read, which caused ADB not to be able to read my phone (adb devices) for some reason. So I had to turn it on, reboot fastboot via adb and then proceed from there. But that was the only issue I had.
So again, thanks a ton for this. :good:

Got problems making this work. Hope you don't mind helping an Android newbie.
Step 7 is to "start client". On Windows 10 I had to disable the virus scan just to see the HCU.exe from the extract. When I click on it I get "This application was unable to start correctly 0xc150002". Ideas? A previous step is to install drivers. I downloaded HiSuite and and made sure I could connect to my device. Does "installing drivers" mean something more ? Thanks.

Nope you are good on the drivers. Nothing else to be done.
As for the error code I recommend disable your Anti-virus and the built in Windows Defender and then re-downloading the program. If it still doesn't work you can try the DC-unlocker program instead of HCU-Client. It should work I just have only used HCU-CLIENT.

Finally got my unlock code! Many thanks to Sandman-007 and foltz61 for their help.
Following instructions from #1 of this thread, I could not (like others here) get the hcu client working on my PC. So here are my instructions on using DC-unlocker instead:
1. Go to consumer.huawei.com / minisite / HiSuite_en/
Download HiSuite. Install it on PC. Connect Phone to PC. In HiSuite click connect to my device.
(May have to enter Developper Mode on Phone: Settings>About Phone>Tap 7 times on your Build number. Enable USB debugging.)
2. Go to www .dc-unlocker .com / buy
Item : New user account, User name you want, Your email, Credits: 4
They will send you a email with a username and password you will need later ...
3. Go to www .dc-unlocker .com / downloads
Download DC-unlocker client to PC. Install it.
4. With Phone still connect to PC, use phone dialer enter *#*#2846579#*#*
Select “Background settings”, “USB ports settings”, “Manufacture mode”.
5. Now start the dc-unlocker client on the PC.
Enter: Huawei Phones (not modems) + Auto Detect + Click Search Icon. You will then see some on your phone info.
6. Click on "Server" and enter your username and password from the email you got at step 2.
7. Click on "Unlocking" + Read Boodloading code. Voila! Copy paste your code somewhere safe!
After giving me my code, my phone shut down. I just re-started it and all was fine.
(To get a better idea, the youtube video v=Lgph755EbKEcovers steps 4 to 7.)

I just did some searching, in my backup images. And I found the unlock code inside the "splash2.img"
/dev/block/mmcblk0p19
Still looking into possible ways to read this from inside the phone, and from locked phone too.
NVM, I think splash2.img is just some type of log file

Is there any other way to get the bootloader unlock code? I tried to buy credits and they refunded me because my paypal is not verified.
Or does anybody out there have a license and would be willing to run my IMEI to get my code? I am at a loss of what else to do.

Why don't you just verify your PayPal or use a credit card?
Someone can't just run your IMEI to get an unlock code. Only way is if they reprogram their device to use your IMEI. That's illegal.
You should NEVER under any circumstances just hand it out. Especially with this tool. Someone with this tool could steal your IMEI and knock you offline.
