Remote wiping my broken N4 - Nexus 4 Q&A, Help & Troubleshooting

Sadly dropped my Nexus 4 and cracked the front screen on Xmas eve which also made it unresponsive to touch. Have luckily got my HOX to fall back on but would like to wipe my N4 before sending it back to my mobile phone insurance firm. How do I do this without being able to use the touch screen?
Thanks guys. Shall we start taking bets on when I get my replacement?

If you have ADB access and can turn on the phone, try using the Nexus Root Toolkit and flash stock/lock the phone. At least that's what I'd try. Only problem I can foresee is you not having USB debugging enabled.

Can you not get one of them Plan B remote wipe apps? The ones that are usually used for instances such as when your phone is stolen?

You can, but if it requires the user to interface with the program to set it up, then it won't work.

If the insurance firm doesn't care if the phone is rooted or not, you can unlock bootloader (with fastboot, from the command line) and flash a custom recovery. Most custom recoveries use the volume up/down keys and the power key to navigate, so you don't have to use touch at all. Then, once you are there, you can wipe it. (You can even get a nandroid backup, transfer it to your desktop, and then do the wipe)

This. And you can lock the boot loader with adb as well, and probably unroot it too, just in case.

I dont have USB debugging enabled. I presume I am screwed?

Yes I think you are as you would have to first enable the developer options and that requires long pressing the build number in the about phone settings. Once the developer options are unlocked you can enable usb debugging. Don't know of any other way to do it though I'm not an expert on adb.

You are never screwed if you can get into the bootloader screen. You can format and return your phone to stock using fastboot from the bootloader screen, dont need usb debugging for fastboot. Hold down power and volume +/- to get into bootloader screen.

Problems with MT4G after digitizer replacement

I picked up a MT4G for cheap with a badly cracked digitizer and decided to replace it. I'm not new to taking apart and fixing small electronics so I didn't feel like there should be any problem. I looked over the videos and info about taking apart this phone, and replaced the digitizer with no problem. The problem came when I booted the phone up. it boots into fastboot but when on none of the hard wear buttons work. I can also boot into Hboot by holding up and down while powering on the phone, but after the phone is turned on again none of the hare wear buttons work. Anyone have any suggestions???
either you broke your ribbon or your ribbon is not fully connected in check agian and try
Well it doesn't sound like you broke anything internally because you can boot into fast boot, you probably wiped the phone of software somehow tho, can you choose selections in fastboot menu by pressing the volume and power keys?

No. non of the buttons respond when the phone is on. The funny thing is the buttons respond during power up because I cab boot into Hboot. I'm going to take it apart again and have a good look to see if anything came loose.

Sounds like a strictly software issue, I'm pretty confident that if you can get adb access you can flash a rom through there. Can you mount the phone to your computer?
In the development section there's a guide for getting adb access, if you absolutely can't get the phone to respond than adb is your best bet.

Installed ADB onto my laptop and got it to see the mytouch 4g plugged in by showing the serial number. When I enter commands I get errors, I think the phone may be toast.
No way dude if it's recognizing it you're in the clear, if it gives you errors try to remount, you might want to get one of the developers on this since I'm not so technically proficient.but I do know that it's completely recoverable as of this point

Do you have any suggestions on who to contact?
Have you tried re-formating the phone?
Hey sort for such a late reply, hope you got it working, try contacting option 94 or any one from team royal.

Need Help Quick Guys About to buy faulty Desire, Volume up and down

Hi guys
Im about to buy a faulty Desire Hd (only 100 euro) seller says works perfect except for the volume up and down key.
I don't mind this as I can use an app for volume control. But is there any way to get into the recovery menu without the Volume up key so I can change roms....
Thanks in advance.
You can always use 'adb reboot recovery' as long as you have USB debugging enabled.

Cheers Mate, Just what I wanted to hear. Can volume be increased and decreased via touch screen during call??
EXT4 has Touch recovery, no volume buttons needed, and works awesome.
Wasn't able to adjust in call volume though with the default sound controls.

How does the adb reboot recovery work?
Would it also work if he gets stuck in a boot loop?
Sent from a dream.
Enable USB debugging, plug in the USB cable, and then on a pc with the android debugging bridge installed use the adb command to reboot the phone.
"adb reboot recovery" will reboot the phone into recovery.
"adb reboot bootloader" will reboot reboot the phone into bootloader.
"adb reboot" will reboot the phone so it boots normally.
Simples!
Don't worry about the buttons, HTC's European warranty is for 24 months, so just send it off for a free repair.

Bloody hell, who let you in?
I had this problem with my phone. Until I dropped it in a massive puddle of water.
Pull my battery, sim card,sd out and left it for 2 days in a container with dry rice.
Put the phone back together hoping it would even just turn on, Phone was fine AND I got my volume buttons back.
I think they just get clogged up.

[Q] Nexus 7 password lock/crack screen workaround please?

I cracked my Nexus 7 screen on the left side and that cracked side no longer accepts touch input. Three letters of my password are on that side and I had orientation locked to landscape mode in my previous use before I cracked it. If I could somehow get to portrait mode I would be able to input my password and use the device with the only limit being my having to flip the device around all of the time when I need to touch the screen in that area.
Anyway of resetting the password or reorientating it from the lock screen? I won't have the money to fix it for about a month and a half and I don't want to factory reset and lose all my data.
I searched for ways to reset password and found nothing useful besides factory reset. I also searched for things I might be able to do by hooking it up to a PC via USB but not one search item turned up was even closely relevant no matther how I phrased it.
Thanks.
Try to turn it on and off?

I've definitly thought of that I won't have any money until next month sometime.
There is a thread on xda that tells how to remove the lock, and it works. Do a search.

boot to recovery and make nandroid backup (if you don't make one yet) then factory reset. You can restore backup later on, easy as pie.
Fix with broken screen and lock
Hey guys,
This will not work for all broken screens. i had the pattern lock and broke 3/4 the screen was not responsive to touch. i was able to use google play store > manage devices. Then change password. this changed it from pattern to a password field. i was able to set a new password that was accessible in the small section of screen that worked.
I was then able to flip the screen in any direction to access what i needed including the usb debug so i could use OTG and get a mouse to control the whole thing. also i was able to get the Bluetooth connection going and control it over my computer and do anything i needed.
Hope this helps someone.

And my three day old Nexus 7 is hard bricked.

I don't remember doing anything to the tablet while I was help my friend with his car. No physical damage from what I can tell or anything. Will not boot and connecting it to my computer results in a HSUSB_DLOAD driver error on my computer.

I couldn't get mine to work a couple days ago. Would not power on. Hold power button for 20 seconds and it booted back up. Hope that works for you.
Tried everything. Nothing worked at all. Showed that driver required that I showed. It requires a jtag to fix
Try holding down the volume rockers and power button. I did the same thing and that fixed it

Back to the retailer for a refund or exchange.... Why do anything else that would waste more time or actually cause more damage?
That's what I did. I didn't have a nandroid backup on my comp for it hence why I wanted to save it.

I actually got to the HSUSB_DLOAD on my computer also. For me that came up if you press vol +/- and power at the same time. The screen will not turn on but windows detects something trying to install. I wonder what that is. Remember to boot into bootloader it is vol - and power. Hope this helps.
Try a different cable. It doesn't brick that easily.

When you say "Will not boot" do you mean you're able to power it on and it gets stuck at the X screen? Or it can't power on at all?
If you're able to power it on, you should be able to get into fastboot mode and restore it to factory settings or flash the stock images.
If you can't power it on at all, then it's a hardware issue and there's nothing you can do about it. Unless you know how to fix the hardware.

[Q] Is my Note 3 dead?

My screen is shattered, but the phone turns on and it vibrates when I turn it off and plug in the charger. Battery lights are normal for charging. Goes from orange to green.
However, when I try to turn the phone on it vibrates once then the blue light starts to blink continuously for a long time. After about 10 minutes the blue light is gone but the back and menu buttons are lit up and stay lit. I can't tell if it has actually booted or not.
If I try to ADB into the phone while it's in this state I can see it listed but it shows as unauthorized.
Does anyone know if I can I revive my Note 3 by replacing the LCD and digitizer? Is there anyway I can test it to see if everything is working besides the screen? I don't want to waste the money unless I know that is the only problem. I would really like to fix it if possible.
There is absolutely no water damage, just a really bad fall.
Try a hard reset with the 3 buttons. If it stays the same then you have a broken phone.

Can you please elaborate. How do I perform the hard reset when I can't see anything on the screen? I know for a fact that the screen is done for. I just need to know if the main board is still salvageable by replacing the LCD and digitizer.

You can't do a hard reset without a screen as it involves booting into recovery, then navigating using volume keys. If you have a custom recovery installed then it's even riskier to try it without the screen. So don't try it.
I'm assuming that the phone doesn't show up as an MTP device when you connect it to a PC?

Thank you for understanding my poor explanation. Yes, you are correct. Phone does not show up as MTP device when connected to my computer anymore. Does that mean I should assume the worst?
Unfortunately, yes. Just a shattered screen wouldn't cause 10 minute long boots every time (blue light only blinks when booting up, at Samsung logo) and the absence of MTP (even with lockscreen password/PIN/pattern the device shows up as MTP but it doesn't show the data unless it's unlocked first). It seems that the logic board of the handset is damaged in some capacity so just replacing the screen and digitizer won't do the trick.

That makes sense! Is there anything I can do to find out for sure if the phone is just in a coma?
I had set a pattern lock so I assume I can't access through adb somehow, right?

Good idea. I'll have to find an mhl adapter and try it. Thank you
If your charging led and hard key lights blink, your phone is good. A display assembly replacement would help.
I received my Note 3 in this way (from a friend) and then I replaced the display and been using it for an year now
