[Q] Locked out of phone... Help? - Samsung Galaxy Nexus

My friend was trying to guess my unlock pattern and after so many failed attempts the only way to use the phone is to input your Google account details. The only problem with this is I had the mobile data and wifi turned off so the phone is stuck on the same screen. Any way of getting past this? If not, any way to restore to factory settings without getting into the settings menu or flash the stock rom? For the first time ever a Google search has completely failed me

I'm not sure the correct key press sequence, but I thinking holding both volume keys while powering on (from off state) should get you into the bootloader, from there you can pick recovery, and in recovery there should be an option to do a factory reset.
edit: once the stock recovery boots, it might look like a warning sign with an android in the middle. from that point you need to do another key sequence to see the options. It's been a while since I used a stock recovery, so I am not 100% positive.

perhaps try and pull the battery and let the phone restart? might let you try and use the pattern lock.

Thank you! Sorted now It was the same key sequence from the recovery screen and got it from there!

I am quite sure that the stock recovery menu does not offer any options.
I know one way which would work 10000%. Go to bootloader mode(hold both volume buttons while switching on), connect to your computer, and then use fastboot(http://koushikdutta.blurryfox.com/G1/) in the console, typing "fastboot oem unlock". This will unlock your handset(not a simlock,just the bootloader), but because of security reasons, your phone will be restored to factory settings. After that just use "fastboot oem lock" to lock the bootloader again if you want to preserve your warranty.

Stop thief!

[q] need help

I bought the kids A100's last year for Christmas. I ended up un locking the bootloader because the ICS update was WAY too slow for my liking. Two weeks ago my sons decides that the unlock pattern is not going to work. You can get the screen to respond in a couple of spots and then go from there but the lines are jittery. I figure that it might need to have a hardware reset. Do that and get a screen with the bootloader info instead of erasing cache..
Find the sd card I had all the info on and tried to do a master rest. NO go. Brings me back to ICS and his lock pattern. I cannot remember how I unlocked the bootloader, did not add it to my favorites or anything else. Now I am stuck. If I am looking at this right the bootloader is unlocked and needs to be locked before I can do a recovery? Is that correct and how do I get that done and do a factory hardware reset?
Worried that if I call ACER with this I will void his warranty.
Power off, then hold power + furthest from the lock switch, press and hold power then toggle the lock switch a few times when the screen turns on to reset. It didn't reset if there is still a lock screen there.
Edit: forgot to mention, holding volume - while powering on will boot into recovery which if its twrp or cwm you can factory reset there, install a new ROM etc.

You definetly need to find out what you have done. As in if the bootloader is definetly unlocked and if you have a custom recovery. Just because it is not neccesary to do anything (ie: root, unlock or recovery) if you just wanted to flash a leaked ICS or the official.
Like Pio said, if you have a custom recovery, boot to it and factory reset/wipe data from there, or flash another rom/reflash. I'm not sure how the tab will react if you do a stock factory reset with the button sequence when you are rooted, unlocked bootloader, and custom recovery.
If the screen only responds in a few places, and is gittery in others, it could be a problem with the digitizer. Digitzer problems are reletively common on the A100. It would covered under warranty if you still have one. If it turns out nothing fixes it, I would restock it though with this concern. They may ***** if they can see it was flashed, if it was bricked it would be a different story.
I used a post on here to go from HC to ICS. Basically It was rolling the HC back first to get the update to push from Acer. I tried to find the post but am having a hard time finding it, and my dumb ass didn't subscribe to it.
This was about in April of this year.
Now when I try to do a hard reset (power + vol down + switch lock) it goes to a black screen with USB bootloader info in the top right corner (near the vol switch). I don't have it with me so I cant tell you right now exactly what it says.
I would have posted sooner, but didn't get emails that there were responses.
Thanks for everyone trying to help. I will try to get back on this this afternoon.

I take it you did the process of going back to HC already and now you can't boot? If its saying its boot loader info in the right corner then its certainly not an ICS boot loader, thats in the upper left corner. It also says ICS in it. Let us know what its actually saying when you boot and we can go from there.

I will. I also turned on the email instant notification that I know that there are responses. Can't believe that I didn't do that before.
OK top left of the screen where the volume button reads:
Bootloader v0.03.13-ics: Starting Fastboot USB download protocol
This time I was able to do the erase user data. Got to the Welcome screen with the language and Country. Cant get the screen to respond.I am guessing at this point that the screen is shot and needs to be replaced (under warranty) however I need to make sure that this is set to Factory specs so that I don't have to worry about voiding the warranty.

It sounds stock to me. From what you have said, I think all you did was revert back to a HC version to get the ICS update ( which some did bck when ics came out if their version wasnt getting the update). If you did this a few months ago, you are just running a stock ICS version.
If that is the case is something missing from the ROM that I cannot get it to reconfigure everything automatically? I thought that it should go directly to the recovery information and reflash the entire tablet (may have the terminology screwed up).

If your talking about Google's sync. If you have it turned on and sync'ed prior to a factory reset, and turned on after. It will sync some stuff, it may restore your desktop wallpaper, contacts, WiFi info and some apps. But it will not restore it perfectly. Either way if your screen is still messed up, I think your OK to warranty it. IMO. Verified if your bootloader is locked, and under settings > about tablet, you are running ICS version 4.0.3 with a stock Acer build number.
I cant get there though. The screen will not respobd to input. I was going to try a bt mouse and keyboard but not having screen inputs puts a damper on that.
And about reconfiguring I was refering to the os and stock software not yhe stuff from play.

Ah I think you mean a factory reset. It doesn't flash anything, it erases /cache and /data (not /data/media but that's another story) and let's the system purge any settings apps or data causing issues.
The system itself is left untouched, if its rooted it stays rooted, if something is corrupted or damaged or missing, it stays that way through a reset.
To replace the system itself you'll need to attempt to flash a stock ROM zip named update.zip on the root of your external SD card and powering on holding the volume - key closest to the lock switch.

[Q] Nexus 7 hangs at "Google", can't enter Recovery

My 2013 Nexus 7 (all stock) hangs at the "Google" screen and won't go further.
If I enter the bootloader and select "Enter Recovery", the screen clears and it goes to the "Google" screen and goes no further. The dead Android with the red triangle/arrow never appears.
Can't connect to it via adb (device doesn't show up) and fastboot just says "Waiting for device..."
Is there anything I can do to recover?
Thanks.

Are you completely stock? Were you attempting to flash anything? Does this only happen when you try to boot into Recovery, or when you try to do normal boot too?
Same thing happen to me, about an hour ago i try to turn on my stock nexus 7 2013, it got stuck on the boot animation, after 10 minutes i turn it off by holding the power button, then wait a minute try to tun it on again and i wont pass the Google logo.
i use it this morning as usual and turn in off like every day i don't know what causes this boot loop.
Any help will be appreciated.

Yup, completely stock. I had the bootloader unlocked but I hadn't ever flashed anything.
It started like this: The screen was dark and the LED notification light was blinking indicating some sort of message. I pressed the power button and nothing happened. I waited a bit and pressed power a few more times. Nothing. (LED kept blinking.)
I finally decided I had to force a reboot, so I held the power button down for the 5 seconds (or whatever) required. The "Google" logo appeared, then the colorful animated logo appeared. After a few seconds of that, the "Google" logo appeared again and hung.
Subsequent attempts to normal boot hung at the "Google" logo.
Attempts to enter recovery hang at the Google logo.

Hmm. That's odd. It sounds like the only thing to do would be to flash the factory image. Luckily, you're bootloader is already unlocked, so you shouldn't use any of your userdata. Follow post #2 from this thread: http://forum.xda-developers.com/showthread.php?t=2382051. Pay particular attention to what you need to modify to make sure you don't wipe your userdata.

I'm not sure how to do that because when it is sitting in the bootloader or after I've selected Recovery and it hangs at the Google logo, fastboot just prints "waiting for device" as if the boot process hasn't gotten to the part where it is willing to participate in the fastboot protocol.
Or am I not understanding something?

Well, fastboot is for when the your device is sitting at the bootloader menu. You may be getting it confused with adb, which is when you are completely booted into the OS. So, boot into the bootloader, plug the tablet into the computer, and open the cmd terminal in your platform-tools folder and type "fastboot devices". You should see your device. I'm assuming you already have the drivers since you already unlocked your bootloader.

I thought I had tried that, but thank you, I'll try again. I appreciate your advice.
Indeed, "fastboot devices" worked at the bootloader. But now I have new problems:
Although I had unlocked the bootloader, the bootloader now reports "lock status: locked" and the unlock icon that had been there during the Google boot screen the day before is now gone. Resigned to lose my userdata, I tried "fastboot oem unlock".
The screen went to the "Unlock bootloader?" screen. I select "Yes" and press the power button. The command line says:
(bootloader) Unlocking bootloader...
(bootloader) erasing userdata...
and then hangs there. I've tried it twice and waited about an hour each time with no progress beyond this. The screen remains on the "Unlock bootloader?" screen during this time. I wonder if this is another manifestation of the hang when normal booting and when going to the Recovery screen.
Suggestions? Thanks for your help.

Hmm. Unfortunately, this is issue seems beyond my knowledge. That's odd that yesterday it was showing unlocked, and today it randomly is locked. If all you did was unlock the bootloader using fastboot, it should still be locked. Did you use a toolkit to unlock before, or did you do it manually with "fastboot oem unlock"?

Can you boot into stock recovery? Without flashing a stock rom or the system image the only thing I can think of would be to do a factory reset. It sucks but it is sometimes necessary. If you are stuck in a boot loop long press the power button to force a reboot, as soon as the screen turns off press the volume down button that will get you to the bootloader. Or if the device is off press and hold both the power button and volume down button to get to the bootloader. Choose recovery with the volume button then press the power button. You should see android laying down with exclamation mark. Press and hold the power button and while holding the power button press and release the volume up button. Stock recovery! Use the volume button to select "wipe data/factory reset" then press power button. If that doesn't take care of it download the factory image and extract, if running 4.4.2 wifi version you should see ;
bootloader-flo-flo-04.02.img
flash-all.bat
flash-all.sh
flash-base.sh
image-razor-kot49h.zip
if you double click the "flash-all.bat" with the device already at the bootloader that will flash the complete image including userdata which wipes the device. You can also open flash-all.bat with notepad and remove -w from the script and it should not flash the userdata.img. Or... you could extract all of the images from the "image-razor-kot49h.zip" and flash them seperately with fastboot, whatever images you try to flash need to be in the same folder as fastboot.exe (platform-tools) so you do have multiple options as long as there is no hardware issue that is causing the reboot. Hope this helps!

Thanks, but sadly this doesn't help me. I'm perfectly happy to do a factory reset at this point, but selecting "Recovery mode" from the bootloader just hangs again at the "Google" logo.
I attempted flashing stock images, but even though my tablet was absolutely unlocked before this happened, "fastboot flash ..." now says "Bootloader is locked." It feels as if whatever damaged the system software also damaged the storage where locked/unlocked is stored.
I feel as if there is nothing to do at this point other than contact Asus about hardware service. Sigh.

Sorry to hear that! I don't remember ever hearing being able to get into the bootloader but not into recovery from there. Your probably right about having to do doing an RMA. If it's any consolation I had a good experience with ASUS when I had to RMA my 1st gen N7 32GB after the speakers went bad.
I'm glad to hear you had a good experience with ASUS support. I have an RMA and am sending it to them. Thanks for your help.
I am having the same exact problem as the OP. Stuck at the Google logo. However, I never unlocked the bootlocker since I bought it (Nexus 7 2013 32GB) back in June 2013.
When I try to go into Recovery, I also get sent back to the screen with the Google logo. It will not enter Recovery so I can Factory Reset.
Is this pretty much going to be an RMA to ASUS. I purchased at Best Buy. Think there's any chance they will exchange?

I would say definitely RMA it. With you having a stock tablet it's not worth risking messing something up trying to fix your tablet and then maybe you can't RMA. I would start with Best Buy and them what their warranty period is. If it is within their stories warranty then take it to them. If not then call ASUS.

Help me
Hello Guys I am stuck in a very annoying situation at the moment which is that my nexus 7 has become inaccessiblhttp://forum.xda-developers.com/images/smilies/eek.gife. This is how it happened
one day I tried to play the android game NOVA 3 on my Nexus 7 on the highest graphical setting so I went and researched how to do this. I was pointed towards some kind of app called 'ChainFire 3D', Once I pressed the install button inside this app the Nexus 7 switched off and the next time I tried to turn it on I got the X logo of death (boot loop). I then tried to enter recovery and I got the annoying 'no command' errohttp://forum.xda-developers.com/images/smilies/crying.gifr. I cant seem to remember how I rooted this thing but I do have access to the fastboot stuff ONLY (inside cmd).
if there is anyone who has any idea how to go about fixing such an issue without wiping everything on my nexus could they please get back to me ASAP.http://forum.xda-developers.com/images/smilies/fingers-crossed.gif
thanks in advance
I have the exact same issue as the OP. Can't get to recovery cause the Google logo hangs there. I can fastboot but the N7 is locked since it was not rooted. Using fast boot and Wugs I get the same thing where it just hangs on erasing userdata for hours. Wondering if any fix has been discovered for this since the OP issue was months ago.
Use fastboot OEM unlock command to unlock the boot loader then re flash stock.

Forgot pattern and Gmail

Hi there guys!
I have a friend who had forgotten his pattern and Gmail account on the m8 and now we can't unlock it
We've tried to make it wrong 10 hoping for a reset as I saw on some websites
And tried to enter the recovery no luck as fastboot is on
Tried adb but he never turned it on
He would do anything to unlock it
From flashing a new firmware to unlocking the bootloader anything for a working device
Actuality I am a Sony user and I am a noob Inn htc stuff
So a helping hand is needed
Bootloader is always accessible, doesn't matter if the "Fast boot" power option is on or not:
Hold power and volume up for several seconds. This will force a reboot. The moment the screen goes dark (but before the white boot screen) release vol up, and start pressing vol down. Don't let go until the white bootloader screen appears.
Or you friend can just go to Gmail on a computer and retrieve their password.

Hard reset using key combo. But it will wipe the data from the phone.
Then after reflashing make a nandroid backup!

Unlocked boot advise, how to get rid of it?

Hi ppl,
I've unlocked my bootloader and now, every time i power on the OP3, shows a screen saying my phone is insecure because it is unlocked, and offer key settings to go recovery menu, etc.
It shows about 3 seconds and continues the booting process.
Is there any way to flash my own image or something to hide it (as i did on my old moto g/g3-te)?
Thanks.
Sergio.
Nope, you'll have to live with it.
You can skip that message by pressing power button, but there's no way to remove it.

Other way of removing that message is to lock the bootloader.
Type in terminal: fastboot oem lock. this will wipe clean the userdata and you'll need to install everthing again.
You can't remove that message with the unlocked bootloader. You'll have to live with it.

Tips for Nougat rooting

Just wanted to pass along some knowledge I gained the hard way when rooting my BLN-24 with Nougat (360).
1) Make sure you have the EMUI 5-specific TWRP and SU. They may have the exact same version #s as their EMUI4 counterparts, but only the EMUI5 versions will work.
2) (This one cost me a LOT of time): Once you "fastboot oem unlock", do NOT let the phone boot to system until you've installed TWRP! If you do, it will FRP lock, and the "Allow OEM Unlock" developer option will be permanently greyed out. With FRP lock on, you won't be able to flash a new recovery (it will error with FAILED (remote: not allowed)).
So after running "fastboot oem unlock" at recovery, the phone will reboot and factory reset. Once finished, shut it down, then start up with USB cable plugged in and holding Volume down + Power on. This will get you back into fastboot where you can now flash recovery or recovery2. If you screw it up and flash the wrong recovery, you'll have to RE-lock your bootloader, then re-unlock the bootloader and go through the whole process again.
Unless there's a simple way around that problem that I totally missed...
3) Don't try to re-lock your bootloader once you've flashed a new recovery. Once I did that, the device would only boot to eRecovery. (Actually, I flashed TWRP to recovery2 so I could still get OTA updates, but I suspect flashing a replacement recovery and relocking bootloader will cause the same issue).
Hope that saved somebody some pain.
Help needed After Flashing berlin twrp recovery . The phone just boots to Revovery.
Thanks for the article Florp . I need some help to fix my recovery issue.
I have flashed the twrp berlin recovery for EMUI 5.x and now my phone just boot to recovery no matter what I do.
Your help will be much appreciated.
Are you able to get to the bootloader (fastboot) screen (USB cable plugged in, Volume down + Power on)?
If so, what does it show for the lock status of FRP and bootloader?

The Bootloader screen says
Phone Unlocked
FRP Unlocked.
If you only flashed TWRP and haven't flashed a custom ROM, I would try to flash the stock recovery for your current ROM and see if that fixes it.
Thanks for the heads up. Good looking out..
