[q] getting past pattern protection screen - Nexus 7 Q&A, Help & Troubleshooting

Hi,
During this week, I dropped my 1-year old Nexus 7 and cracked bottom left 1/3 of the screen. It looks as if the device is still functional, but I am not able to get past the pattern protection that I have used as a security feature. Is there a way to get beyond this screen to see if it still is a functional device and if so, then disable the pattern recognition. I am resigned to the fact that I may have to buy a new device, but I do not like to discard it without trying if I can get some additional service out of it somehow. By the way, it is an unlocked, but unrooted device.
Thank you for any help/suggestions.
Best Regards,
RaliR

the display is ON right?

The same happened to my Nexus. The device is good. Just get a replacement Screen+Digitizer (cost around 66$ with free shipping in ebay(tools free), let me know if you need the link). And you can fix it by yourself(I did) with the help of "How to replace glass in Nexus 7" video in youtube by Android Authority!

Hi Nijom,
Thank you for your reply. Before I spend money to get a replacement glass(& digitizer), I want to see if there is a way to get past the Pattern Protection screen to make sure that my device is fully functional. I do not want to spend $66, replace the glass and then find that the device is not working. Any thoughts, Anyone?
Thank you,

The only way to do it is to erase the file that contains the password. You won't be able to do this from a booted device, at least assuming you are running 4.2+ and USB debugging is off/your computer isn't authenticated with the device. You will need to flash a custom recovery if you do not have one already. Once you boot into recovery, you have two options. You can either use the file manager built into TWRP recovery, or you can use ADB. You need to delete the file /data/system/gesture.key. Use the file manager to delete it, or run from your computer:
Code:
adb shell rm /data/system/gesture.key
This will only work if your screen is still partially functional; it doesn't disable the passcode lock, but it erases your saved pattern so that any pattern will unlock the device. If you are able to touch any of the points on the pattern lock, it will unlock the device. Once unlocked, you can remove the lock screen, assuming your touch screen is functional.
And yes, this is an inherent security risk with unlocked devices.

[Q] Android geniuses, help me! Smashed Nexus 4 screen after 6 days, options?

Hey guys I need some advice on what to do with my Nexus 4 - I had it for less than a week when it slid right onto the kitchen tiles, and as a result I have an unrooted Nexus 4 with developer options disabled, a pattern screen lock and a completely smashed and unresponsive touch screen.
I don't want to fix the screen if I can help it as I would just end up selling it and would basically break even on just the repairs.
From my current position is there any way to get the phone functional in terms of being able to use a keyboard and mouse with it, perhaps as a server or some other capacity like that?
Please list any and all ideas of how you would proceed from here, from the research I've done it seems as though I'm severely limited by the fact I can't change certain settings without the touchscreen working (Such as getting OTG working)
PS. I don't care about getting data back, just want to be able to use the phone in some way so it's not a complete loss, if possible!

I wonder how did u think of such S**t with this Lovely baby.
You had FUN! Now just pay the price for having fun with the unresponsive screen. Njoy.
Rohit :/ He didn't mean it literally. you are shame for us Indians..
OP - nexus 4 can't output enough power to use a keyboard or mouse.. Boot into recovery factory reset and flash a kernel that supports OTG. Then MAYBE with a Y-Cable you could connect a device to use.. though I doubt it.. Go to your nearest LG shop and repair it and BUY A CASE.

PS. I don't care about getting data back said:
1.Cough up $150 to LG to fix it.
2. Read the return policy. In 2012, It stated you can "return the device for ANY reason within 14 days". In 2013, its been revised.
3. Sale it on amazon and ebay for $200-250.

Backup w/ Broken Screen? (TWRP Installed)

Hey guys, I recently broke the LCD on my Note 3 running stock KitKat ( :crying: ) and realized I hadn't done a nandroid backup in quite some time...
I tried the obvious adb pull, but for some reason I couldn't even get into adb shell or see my device in the device list like I had previously.
I'm all out of ideas now...
Could somebody please throw some help my way?
Does your phone even boot up? Do you get sound, vibration, anything to indicate it's still working internally beside blank screen?
Are you going to try to fix it? buy new one? upgrade to Note 4? Me and my wife used to own GS3 and when she broke her screen, I swapped motherboard with mine to copy pictures mostly and some other stuff, but we werent going to fix it, since I decided to get her GS5.

I'm getting a replacement through the phone insurance. It does turn on and function perfectly normal, the screen just has a tiny, tiny fracture point with a crack spanning across the screen horizontally, rendering the bottom half unusable. The top half is functioning though.
I cannot unlock my phone or make a backup with the bottom half not working.
Try using a bluetooth mouse or wired mouse with otg cable

Could help, made for exactly your problem. If you manage to get it working download Nandroid Offline backup, which allows you to make a Nandroid backup from Android itself, rather than CWM/TWRP.
EDIT -- Just checked and it works an absolute treat. Providing you had USB Debugging enabled before your phone got broke, it should work fine. It even has the option to swipe to unlock or disable a pattern unlock if you had one enabled.

Thank you for the link - it looks like it would be a great solution, but unfortunately I cannot enable USB debugging with the code given :\. I may be out of luck
Well, if nothing else works and data on the phone is that important, then you need to convince the insurance company to send you new Note 3 first and swap the MB as I suggested to retrieve the data, then put everything back to original. I have not done this on Note 3, but GS3 was probably one of easier electronics repairs I've done, just follow one of many youtube videos, to make sure you don't break some wire, before disconnecting. Possibly a shop could do that for you.
Well, freakin sweet deal. After being on the phone with the insurance company and US Cellular for two and a half hours and having them tell me everybody was out of Note 3's and they would only give me $400 bucks for my old phone minus my $175 deductible, I received another call from management at the insurance company apologizing and letting me know that they'd offer me $725.
It just so happens the new Note 4 is $770, so thank the Lord I'm in a good spot!

[Q] Screen smashed, stock 5.0, need to retrieve data

Hi everyone. The screen on my nexus 4 has smashed and unfortunately I can't access anything on the phone. It would appear that since flashing 5.0 OTA as well my bootloader has relocked and the phone is not rooted. Additionally, there is no recovery installed and I won't be able to adb. There is a password on the phone so I'm unable to connect to my computer to access the files...
I really wanted to retrieve all my photos off it and don't really trust sending it to a third party. Is there any way I can access the mass storage, take my photos off the phone/delete them? It's a backup phone so I flashed 5.0 OTA without really thinking about it, didn't realise at the time that it would relock my bootloader and delete my recovery! Very frustrating.
Additionally, I had planned to use OTG to just use a mouse on it and unlock it via password and grab the stuff I wanted, however they took away the OTG mouse feature, very annoying! If anyone could help get that running too despite being completely locked down that would be helpful.
Thanks everyone.
Your best solution
There is a simple solution
You need to replace your screen.. If you buy a "LCD/Digitizer with Frame" on ebay you can replace your screen. This will bring your Nexus 4 back to life. It is easy to do. Just make sure you get a "LCD/Digitizer with frame" It will cost you a few dollars more but will make the job very easy.
check this youtube video it will show you how in detail

Nexus 6P angler-userdebug 8.1.0 question

hello, my first post, I bought a Nexus 6P from ebay. It has an unlocked bootloader (I get the warning when I turn it on) and the os build number is "angler-userdebug 8.1.0 OPM3.171019.01445.3998 dev-keys". there are applications that are not uninstallable: Better Bug, Nexus Logger, Traceur, and Volta. My question is, is this device suitable for personal use the way it is? any other information and/or suggestions are appreciated.

I am not sure about the rom version.

It sounds like somebody sold you a former test model from Huawei.
I can obly assume, that they sold remaining units, but after I searched a bit about those applications I can, like I said, only give you a vague assumption.
The important questions are -
Is the phone functional?Meaning: bootloop, sudden reboots, battery problems?
Are you able to use adb/fastboot? - > Is your phone being recognized by the command 'fastboot devices'?
Did you get a notification that is your system can be updated?
The unlocking of a bootloader isn't a reason to be distinctively suspicious?
But, if you are not satisfied with the phone in whatever way, you can demand to be refunded in regard of the unlocked bootloader with the argument, that the seller has tampered with it and should wrote it in the description.
I bought a phone a while ago and were unsatisfied with it, so I argued with the above mentioned and got my money back.
This was even from somebody private and there are no refund policies, besides the buyer protection.
If you have not passed thr chance and don't want to have a phone, which somebody has used most likely to flash a custom rom or recovery to root same phone, then go for it.
It is not a 100% bulletproof argument, but ebay excepted it, at leat in my case.
If you are okay with the device and adb/fastboot are working, in a way that you for example can test some commands, whicj you have to look up, but __don't flash anything__ as long as you are unsure of the condition.
If you want to remove these apps, you have to look them up, which is expandable and which isn't, before removing them.
And lastly - if you want to remove them, you have to root your phone (tutorials find you here en mass, the same goes for adb/fastboot usage).
But the same goes here for testing a ADB and fastboot usability, please.
If you decide to keep it, then you can remove system apps (>before a search if you phone goes boom..), aith this app for example
https://www.apkmirror.com/apk/jumobile/system-app-remover-root/system-app-remover-root-7-1-release/
With this, you are able to backup the apps if you want to remove them.
Some apps, especially the so-called 'bloatware' is from now on then, quite resistant.Just empty the trash, which you find in the app's menu.
Titanium Backup, a very, very versatile application, is fir example capable of backing up your entire apps including data, but I think, you have "some" pointers now and can give it (with carefulness) your own try.
Have fun & good luck

Broken Phone HELP PLZ ?*♂️

Hi, so I recently smashed the H*** out of my Essential Phone. I put my sim in my wife's old Nexus to try and get back into the Gmail account I've had for 10+ years, and they've forced 2 step verification onto my account and will not let me use my number for recovery. The ONLY way to complete this verification is to use my Broken Essential Phone to accept screen prompt. So here's my question... I was rooted, with TWRP and Custom rom but do have Full Back ups on my computer, so if I were able to get another essential phone and root it, would I be able to then restore the factory image and back ups I had created for this old essential phone onto the new device and gain access to my Gmail account that way, or am I totally out of luck unless I fix my smashed phone enuf to get to the screen on to accept screen prompt to verify my identity....? Any insight here is greatly appreciated. I have 1000's of $$ invested in that Gmail and have been unable to access it for a week now. Google has been zero help. Sorry if. This is posted in the wrong space, I haven't been here in a while.

A few years back you used to be able to get a new phone install TWRP create a backup on new phone and then copy the files from the old phones backup into the new backup folder (with the new unique file number). But think I read this doesn't work anymore on new version (but not sure you'll have to check yourself or hopefully someone here knows)
Even if that works what type of 2FA is it? Authenticator or SMS?
https://support.google.com/accounts/troubleshooter/4430955?hl=en
without a backup code it may not work anyhow
if you can see your screen but touch is not working just plug a mouse into the usb & click away! If screen is blacked out but rest of hardware good easiest to buy a replacement screen as cheap or use usb-hdmi hub to mirror screen (not sure if Essential phone requires any input to set up as haven't tried with this phone)
If other hardware damage it will depend, but as rooted you are in with a chance. Is usb debugging on?
Thanks for your response, Google has been zero help and I've definitely considered ordering a screen to see if I can get the old device to work, but the og screen is detached from the chip board, as far as I can tell it will power on with some serious prompting, but idk if it's actually trying to boot up or in some kind of safe mode detecting the screen is missing, or just wrecked completely...? Lol the notification Light stays red until the battery dies. I've considered maybe trying to clone the esn of my old essential phone to another phone to try to trick their servers that way but idk if they recognize the device via that (The ESN) or tokens generated locally on the device, and the more I think about it, the more I think the latter sounds more logical considering the nature of the beast I'm fighting here... Seems It would b wildly irresponsible of them to rely solely on esn to identify a "Trusted" device. Idk what to do, lol except cry... I'm basically at a loss at this point, so I will order a screen and go from there I guess, if the screen option doesn't work. You'd think with the money they have, they'd have some type of account recovery team, or a way to recover in the event something like this happens, or someone to speak to at the very least, the can verify my account in seconds over the phone, but do literally nothing for me, nor let me speak with or point me towards anyone who can.... And this is a pretty common issue it seems after lookin at their "Community help section" it's literally top to bottom ppl complaining about what I'm looking to "get help" with. There is zero reason they should be forcing 2fv on my account it's shut off in my account settings, I can get far enuf to c them, just doesn't let me change anything with out "Signing in" and verifying. Nor does it give me the option to use my only ACTUAL set up recovery option on the account, a code via text. It's almost like theyre protecting all my own s***, from me. The owner. Makes zero sense to me.
It sounds like when you setup the essential, you configured your Google account to use the *device* (via the Google app) for verification. I've done this also, but I have an old device also configured to authenticate. So the pop-up screen appears on both.
If you use a computer to log into your Google account (not gmail) on the screen that is waiting for verification, there should be a link to try a different method. Hopefully you setup a secondary email address in addition to the gmail account one.
Edit: start here https://support.google.com/accounts/answer/7682439?hl=en
OT: I realize you are frustrated, but it would be easier to pick out the relevant information in your posts if they were not one long paragraph.
