Hi All,
I tried to complete a manual update of the 4.3 OTA on my Nexus 4 this evening, however unfortunately it didn't work and my phone would not boot past the 'Google' screen. After wiping the cache, and still having the issue, I decided to do a factory data wipe/restore. However the problem still persisted.
With this, I thought the only way past this was to install the factory image. I installed the 4.3 factory image just fine (after going through the various steps, including unlocking the bootloader) and it was up and running for a while installing apps. However, with this, the device had a black/blank screen for a fair few minutes and after leaving it I thought I might has well reboot. Unfortunately, this time is did not boot again.
So; off to do the same previous steps again.... fastboot oem unlock (as I relocked the device previously), load bootloader, etc, etc. Got to the system update, and it passed an error saying that fastboot is not available on a locked device. Strange as I had unlocked it, but there is was on the menu "LOCK STATE - locked"....
I am now at the stage where I can't actually keep my phone unlocked. I can complete the command fastboot oem unlock, but once I complete fastboot reboot-bootloader, the device is stating it is locked again. - This is where I need some help, PLEASE.
Sorry for the long post, but wanted to describe the situation. If you need further info from me, just let me know. I'm hoping someone far wiser than I am can help me resolve this issue...
Any help on this? - It would be much appreciated.
I too have the same problem with my phone
but my phone is 4.2.2. rooted and wouldn't load past the 'google' boot screen
I can still go into clockwork recovery mode and I wiped cache, did factory reset and I can't even access my phone through the computer

Hi everyone. Here is the deal im having with my nexus 7 (not the 2013 model) with jop40d.zip. The person I purchased from didnt tell me it was soft bricked. It seems as though he tried to root it but failed while at the same time relocked the bootloader. So I've tried almost everything in my mind to get it back to normal. It wont let me adb sideload the stock rom it says "installation aborted" or any other rom. Also when i boot up it goes directly to the bootloader which gives me the options start, restart bootloader, recovery mode, power off. start obviously does nothing. restart bootloader just for some reason turns the device off, recovery mode takes me the caution sign where i can adb sideload or factory restore. factory restore hangs and doesn't do anything then shuts off. adb sideload always fails when loading up the zip files. i factory restored the cache. I'm not sure what to do anymore. I spent a fair amount of money on this device but now it all seems like a mistake. Can anyone who has fixed this issue help me out? I would deeply and greatfully appreciate it.
-Cheers

also I wanted to add. I have the android sdk installed and all drivers installed properly. as well as adb/fastboot.
Stop trying to use adb, follow the sticky at the top that says flashing a factory rom using fastboot/return to stock. If you can't type fastboot devices and get a serial number return then the drivers are not installed properly.
Sent from my Nexus 7(2012) that has zero issues.

hey slow cobra. yes fastboot does recognize the device. however fastboot oem unlock doesn't do anything.

I have a Nexus 7 sitting in front of me that was dropped off by my aunt in hopes that I could repair it for her. It doesn't look too promising, but I thought I'd consult the mighty fine people here on XDA before I give her the bad news. Here's what she says happened. Yesterday, while preforming day to day activities on it (browsing internet, Skyping, Facebook, etc), the device completely froze. After holding down the Power Button and forcing it to shutdown, she booted it back up. Everything seemed to functioned properly for about 30s - 1min when, at that time, the device turned off and rebooted on its own. After booting back up, it started to repeat this cycle. Basically getting stuck in a bootloop. I personally have never witnessed a bootloop like this before, where the device successfully boots up completely into the OS before turning off and repeating. I'm more used to dealing with ones where it might go as far as the manufacturer logo and then repeats. So anway, as I stated, I only have a 30s - 1min window where I can make changes in order to troubleshoot. The first thing I figured I should do was to go into "About Device", turn Developer Mode on and get USB Debugging enabled. I was able to do this and used "adb devices" to confirm its connection to my computer before it looped again. After its next bootloop I headed back into settings because I wanted to take note of the Android version she was running. As I was navigating there, I noticed that the Developer Options were no longer active. Basically as if I hadn't enabled them yet. This made me start thinking that changes being made on the device weren't sticking. I decided to make a few visual changes to the home screen and see if they were still there after the next bootloop. I uninstalled an app, rearranged icon placement, and changed the wallpaper. Once it shutdown and booted back up again, everything was back to the way it was before the changes had been made. The app I had uninstalled was still there, the wallpaper reverted back, and the icons were back in their original location. At this point I decided to see if I could reboot into Safe Mode. Unfortunately, this doesn't work. I am able to get the reboot to Safe Mode confirmation box and tap "Ok" but it remains in Normal mode when it boots back up. I eventually tried to boot into recovery and preform a Factory Reset. I was able to get into recovery and reset the Nexus. Or so I thought. Instead of seeing a Device Setup screen after it wiped, like I assumed I would, it booted up and still had all the data on it. There were no errors during the wipe and it was confirmed with "Data wipe complete." afterwards.
I am absolutely lost. I've never dealt with such an unusual issue before. Especially with it not even reacting to a complete data wipe. So, just to recap . . . I only have 30s - 1min available to interact with the OS before it reboots itself, any changes made during that time don't stick, Device is successful booting into Stock Recovery, and I can successfully get a Fastboot connection when booting to the Bootloader.
Luckily she has come to terms that this might not get fixed and has decided to go a head an order a newer 2013 model. I'd still like to try any solutions that you all might have. Just in case there is a slight glimmer of hope.
Oh, and one last thing I should mention. I tried to see if I could get the bootloader unlocked but it didn't work. This is the first Nexus I've ever had in my possesion, so I'm not really familiar with the tools available for it. I found WugFresh's Root Toolkit and attempted to Unlock with it. The process seemed to go as it should and I didn't receive any errors on the tablet or in the software. However, in the end, it didn't make any changes to the bootloader.
same problem
I have the same problem as you.
Did you find a solution?
Can anybody help us?
Thanks.
I have a similar problem, but I think mine is related to the bootloader.
I'm stuck on 3.34 and that's where it fails ever time I try Wug's Nexus Tool Kit.
Have you tried Nexus Tool Kit yet?

I have tried factory reset from recovery, no errors while wiping but when device restarts nothing has happened: I only have a 30s-1min of old system with all my data and apps or directly bootloop.
Also I have tried flash factory images with Nexus Tool Kit and directly from bootloader. No errors while flashing, apparently has flashed new image system. When device restarts nothing has happened: bootloop or my old system with data and apps for 30s before restart.
Myself and a few others are having the same problem... please keep us updated if you find anything out.

Hi,
Yesterday my Nexus 4 decided it no longer wants to boot up. It just sits on the boot animation and doesn't progress any further. I don't think I have done anything to cause this - it was working fine the day before and I haven't installed any new updates/apps or really changed anything on it.
It is running android 4.4 with stock recovery etc and no root or bootloader unlock. Unfortunately I need to recover the data stored on the phone because I don't have any recent backups but I can't figure out how to do that. I vaguely remember turning on usb debugging as a precaution many months ago but I can't remember whether I actually left it on or not.
Any suggestions on how to recover the data? I've already looked at quite a few threads on this, but most require an unlocked bootloader which I can't do because that will wipe all the data. I can't use adb pull because the device doesn't get detected. I'm not that experienced with adb, fastboot and command lines so some help would be appreciated.
I have wiped the cache through recovery mode and tried using the "sideload adb" mode in recovery mode and neither worked. I also can no longer get the options to appear in recovery mode for some reason.
Thanks for your help.
I recently successfully restored my Axon 7 (A2017U) to B20 and tried to OEM lock it again. After running "fastboot oem lock", the phone rebooted, but came up with something that said "To start Android, enter your password." I didn't have a password before, so I tried something I found online called default_password to see if it would unlock (which it didn't) & then other passwords to get the phone to wipe itself and essentially perform a factory reset. However, now it is stuck in Safe Mode and says "Decryption unsuccessful: The password you entered is correct but unfortunately your data is corrupt." When I try to wipe the phone, it says it is factory resetting, but then it restarts and goes to a blank screen. (Which I suspect is because TWRP is still installed as a recovery, not stock). In addition, power+volume up no longer works since the phone is oem locked, but power+volume down takes the phone into Factory Test Mode. My computer still recognizes the phone when it shows up in Safe Mode, but I cannot see it in ADB.
Where can I go from here to factory reset the phone? Is it possible to send this to ZTE to fix since it is OEM locked at the moment?
I followed razorblader's advice and successfully got the phone into EDL mode and ran tenfar's tool. However, that made it worse and now the phone just shows ZTE for the second & the screen goes blank.
EDIT: Nevermind, I was running that program without recovery.img/boot.img in the same directory, D'OH! Luckily, I still had comms with the phone after that mistake & I re-ran the program successfully. I can now get into TWRP recovery. However, booting into system still shows the corrupt data message. I'm going to try a factory reset from TWRP and see if that fixes the issue.
OK good news, got my Axon 7 working again, stock + locked & am currently posting this from it. One reason I wanted to relock it however was to get OTAs and right now B27 is showing up. Now before I almost brick my axon again, do I need to flash stock B20 recovery before I'm able to install this update? Also, I'd like to get to B29 eventually, but I'm guessing I need to update to B27 first. (correct me if I'm wrong though)
I replaced my GNEX10 battery last january. Aside from the battery calibration being off... (which eventually corrected itself!) it's been working fine. As of late it had rebooted itself while I was using it a few times. A few days ago, it had enough battery such that I left it on overnight. I picked it up the next morning and the notification lamp was flashing so I knew it was still on. I tried to wake it up without success. Usually a quick tap on the power button should do it. Nothing. So I rebooted... and on the google logo it stuck. I knew that a factory reset was probably in order since I didn't do it when I replaced the batter... I got it into the recovery screen... but I could not get the menu. I likely didn't press the right volume rocker. Then I tried again... booted to the bootloader, and selected recovery. This time, and since, only the google logo comes up. No andy on his back with "no command". It just tries to boot into something. I can't do a factory reset this way.
I tried the Nexus Root Toolkit. I can only get it to recognize the device if it's in the bootloader... when I try to use it to boot to recovery, same thing and the NRT says waiting for device... and gets no further. I tried to use it to flash (stock?) recovery but the N10 just sits there on the twrp logo screen and nothing more after temporarily booting into twrp. Just keeps saying "waiting for device"
Anyone have any suggestions! Getting seriously bummed!
So one more data point... I manually rebooted into the bootloader after trying to flash the stock recovery using the NRT. Then it appeared to flash the recovery image.... here is the bit of the log where it ended up:
Checking Fastboot Connectivity
fastboot devices
R32CB04GHGT fastboot
+ Fastboot Device Connected
Flashing Stock Recovery to RECOVERY partition...
fastboot flash recovery "C:\usr\NRT\data\Recovery_Stock\recovery_stock_mantaray_5.1.1_LMY49J.img"
Temporarily Booting TWRP...
fastboot boot "C:\usr\NRT\data\Recovery_Custom\TWRP\twrp-3.0.2-0-manta.img"
Flashing 'undo-perm-recovery-signed.zip'...
Waiting for your device...
That's where it ended up... not getting any further. Once again, attempting to boot into recovery gets it stuck on the Google logo.
How screwed am I? Is there a thread somewhere in the forum anyone can point me at?
Well, in spite of the crickets... I understand. I've managed to resurrect my Nexus 10. Alas there are no good contemporary replacements. The last so-called nexus table google put out there was too damn expensive in the first place and they seem to have abandoned the tablet market to others.
So the key question here: So long as I can get this tablet into the bootloader is it generally possible to reflash a stock image? I'd like to know of any types of caveats etc. The mystery I have still though is: How or why did my N10 get into this state (of of only being able to get to the Google screen) in the first place? I didn't have any questionable apps installed etc. I was totally on stock. One thing that did happen a week or two prior to my tablet going belly up... was somehow the thing lost my google account info and gmail had none of my accounts in place... it was very odd.
I did have to wipe the system because evidently you can't flash anything onto a locked bootloader (the Nexus Root Toolkit by wugfresh is up to date so far as the N10 is concerned at least). I know I could have resorted to using fastboot.exe and the adb directly but this was a touch easier. Alas the backup options for it say you need an unlocked bootloader which seems to be a chicken/egg issue if you've always been on stock.... so it goes.
