Nexus 7 2012 Retrieve data without USB debugging, Bootloop. Solved !! - Nexus 7 Q&A, Help & Troubleshooting

Hi hope I have come to the right place for help. My Nexus 7 16GB 2012 wifi is freezing after the google logo during the boot animation of the spinning circles and stays like this. I have done some reading and I can get into recovery mode and would like to retrieve pictures/personal data but I have not enabled USB debugging, have a stock rom kitkat, but not sure which version, and have a locked bootloader, not rooted. Is it possable to still get the data off of the device. If someone could point me in the right direction it would be much appreciated.
Thanks in advance for a response

Use adb pull command

Ok Im not familiar with this programme but have read a bit about it. I will try and venture into this alien world of abd and see what happens.

Installed Minimal ADB and Fastoot, connected the Nexus installed the ADB driver from Asus in device manager. Booted into the bootloader and when I used "Fastboot devices" I can see my devices seial number. When I try "ADB devices" nothing is seen. I have read I need USB debugging selected and the device booted to use ADB, both of which I can not do as I am stuck in a boot loop.

You can't use adb in fastboot mode. It seems possible to pull files with fastboot, but it isn't fun.
Maybe you can flash something via fastboot to make it boot again? That would be the best way imho.

Go to recovery and try adb commands. In bootloader you can use only fastboot commands.

Ok I booted to the bootloader, from here selected recovery where the little Android is laying on its back. Now device manager showed nothing connected. Used the power + volume-up combo to get to the four recovery options, still nothing in device manager. Selected side load adb option and bingo welcome sound of device being connected. Windows didn't find a driver so downloaded adb driver from Asus but device manager refused to use it. Did some reading and downloaded Koush's universal driver and now device manager showed device connected and driver installed. The ADB devices command now shows the Nexus info. Now to learn the pull command. ....

Done lots if reading on this and think I am beat. From what I have read the with the Nexus 7 in its current state (stock, locked bootloader, unrooted, no usb debugging) the sdcard is not reachable through the stock recovery sideload option in any way. I had a ray of hope from the above link to pull files via fastboot but I have read the thread and it seems the person says it was misleading information that they posted. I followed information in another thread and tried extracting boot, recovery and system files from a nexus factory image and flash them via fastboot but it fails stating the bootloader is locked. If I unlock the bootloader I will lose the sdcard data I want, as I will have to perform a factory reset. So as suggested I could install a CWM/TWRP recovery, but to do this via fastboot I need to unlock the bootloader......
I am thankful for people taking the time to help and for all suggestion posted but unfortunately I can not find a fix. I would be sooo grateful if someone could prove my finding wrong....
Off to do some reading about mounting the sdcard via adb shell but don't think this will work via stock recovery

Can't get the nexus to boot up, just bootloader and recovery accessible so don't think I'll be able to do this.

Sideload fix
Managed to fix this without losing anything (sdcard, docs, pictures, apps, setting etc). Took a while mostly due to lack of understanding of fastboot and ADB sideload from the recovery options.
Lots of posts advising to boot into the bootloader and use adb and fastboot. Everything I read to do with using fastboot commands via the nexus bootloader (insatalling boot/system/recovery etc) involved having an unlocked bootloader or having to unlock it as in my situation. This of course involves a factory reset of the Nexus resulting in a loss of the data that I was trying to retrieve, so i ruled this option out.
As suggested I should try the ADB pull command, but because I had not previosly enabled the USB debugging option via the setting menu everything I read said this was not an option. Read in one forum post something like "As you have not enabled USB debugging ADB is dead to you, just flash a factory image via recovery".... and lose all your data... this is not what I wanted to hear so I abandoned this option aswell.
Then I discovered sideloading. With this you can manually install an OTA update (the ones that pop up in your notification window saying something like "System update available") via the Nexus recovery option "apply update from adb". This does not invlove wiping any data , apps etc as it would just install the differences between what you are currently running eg. 4.4.2 and the updated android you want to go to eg 4.4.3. This is different to flashing a full factory image via fastboot were everything would be erased/formatted and an entirely new install would be flashed. Of course... simple when you know what the option is for and what you are doing. Of course I had had no clue what sideloading was all about.
So with my new knowledge I downloaded an OTA update from here:
http://forum.xda-developers.com/showthread.php?t=1745781&highlight=4+23
but wasnt sure what version of KitKat was running prior to the bootloop. I knew it was somewhere around 4.4.2.. so took a chance and tried KTU48L from KOT49H (4.4.3 from 4.4.2) and copied it to the Minimal ADB folder.
I booted the Nexus to the recovery mode and selected "apply update from adb". The tablet then conected to the PC (windows) as shown by Device manager. (I used Koush's universal ADB driver as windows failed to find anything of use). https://plus.google.com/103583939320326217147/posts/BQ5iYJEaaEH
I opened Minimal ADB downloaded from here
http://forum.xda-developers.com/showthread.php?t=2317790
and typed "adb devices" which showed the Nexus was connected.
I then typed "adb sideload nexus OTA file name.zip"
Lots of sending files messages appeared in the adb window the Nexus disconnected from the PC and showed this...
Finding update package...
Opening update package...
Verifying update package...
Insatlling update...
Verifying current system...
Removing unneeded files...
Patching system files...
Patching boot image....
Unpacking new files...
Unpacking new recovery...
Symlinks and permissions..
Patching remaining system files...
script succeeded: result was [/system]
Install fromADB complete.
All looked good so I rebooted the Nexus but I was still stuck in a bootloop at the four spinning circles. I tried clearing the cache from the recovery menu several times powering it down and leaving it to boot but after half an hour accepted failure.
So I tried downloading KTU84P from KTU84L (4.4.4 from 4.4.3) and repeated the procedure. this time not as much files seemed to be sent to the Nexus, I guess this was just a small update. Again it showed "script succeeded" but still failed to get past the spinning circles of the boot animation.
Thinking I was defeated again I was going to give up but tried downloading LRX21P from KTU84P (5.0 from 4.4.4). This time when I sideloaded a mass of files were sent to the Nexus much much more then the other two updates, obviously KitKat 4.4.4 to lollipop 5.0 was a big update. Again I got the "script succeeded" but this time I got the new Lollipop boot animation and the Nexus fully booted.
I can only guess that the big update to Lollipop removed or replaced files or did something to replace the faultly part of my install that other OTA updates did not change.
Anyway I did not find any other fix that advised sideloading an OTA update to fix a bootloop, maybe I just looked in the wrong places. I tried to write this in laymans terms for non techie people in the hope that it may help someone else in the same situation who like me knows very little about android.
Thanks to the forum for the information...
Also link here with some info about half way down page on effects of usb debugging being enabled for sideloading, and near the bottom of the page a good link to a sideload pdf guide.

[Q] please help with my nexus....

I went to flash cyanogenmod 10.1.
backed up rom via clockwork.
wiped data, flashed new rom.
flashed gapps.
I think i flashed the wrong gapps
upon boot I get "setup wizard has stopped" as well as one regarding gapps.
this prevents me from using the rom. I can access the calender and clock that is all. not the settings or reboot menu.
I can access the built in storage via windows, shows up as a nexus 7.
Ok, not a big deal, I will boot into recovery via the bootloader.
That no longer works. Sits at a google screen forever
Ok, I will use fastboot via the bootloader....
That no longer works. As soon as a usb cable touches the nexus either power or pc it freezes the bootloader requires a reboot.
windows rejects the usb and states is malfunctioned and unrecognised (though it works fine in the rom)
fastboot doesn't see the device.
I've tried:
three usb cables.
windows safe mode.
different ports
uninstall/install drivers.
nexus tool kit (doesnt recognise device)
wiggling the cable as suggested
anybody got an idea how I can either get the bootloader not to freeze when using a usb cable or how to boot into some kind of recovery (which was there!!!!!)
please? :fingers-crossed:
Something seems a little off here.
Was it a gapps package for some other device? Hard to see why flashing something to /system would produce the result you got, as the (gapps) edify script would at most specify a mount of "system", not a /dev/block/ device name.
Does adb work (with the ROM booted)? If so, can you get a root shell or install .apks?
The fact that the ROM boots suggests that the bootloader is working correctly enough to load and execute the LNX (boot) image. That means that in principle you could flash (using the "dd" command) a recovery image to the boot partition from a root-privileged command line (either an adb session or a terminal emulator). Performing a regular (power button) restart would boot you into a recovery session.
Obviously, this hinges on you getting a command line somehow with your reduced-functionality ROM limping along as it is. It's not obvious to me how you will make that happen though.
I am not at all confident that this will fix the bootloader <--> USB issue without somehow reflashing the bootloader without using fastboot!. The only way this has been observed for the N7 has been with the OTA process and a stock recovery - the OTA puts an image (**note - important!** this OTA bootloader image is slightly different from the bootloader image in the factory/fastboot ROMs) into the USP partition and some magic occurs on the next boot.
Well, anyway there's some ideas. Would you mind identifying the "wrong" gapps that you used? For the life of me I can't see how it caused the symptoms you are observing...
good luck
Hi. Many thanks.
Ok.....
Gapps. I downloaded the appropriate package via the link on the Rom page. However, I flashed a jellybean package I'd downloaded for my one x. I may be naive in thinking that Gapps is Gapps no?
I deduced it was that having googled the setup wizard problem and seeing that others had had it.
Bootloader.
Again. Ive googled around and can see many have the freezing bootloader with usb issue. Some say its the cable. Some say its the pc. But it does it with the charger as well. Again this is an issue for some. not sure what to do! Works fine until the cable goes in.
Recovery.
Again I know its an issue booting recovery from bootloader. I've read you need the usb in to a pc to make it happen. Obviously that's a no go for me
Adb.
Never really used it. Used fastboot many times. I assumed you need to be able to access the developer options and activate debugging etc within the Rom to allow it to work? I can not do that. Its around 10% funtional. I can place a reminder on the calender but that's about it! No way to system settings.
Sorry if thats teaching you to suck eggs. You obviously know your stuff, just wanted to make it clear.

A normally functioning tablet does NOT require you to be plugged in to a PC in order to boot the recovery from the bootloader menu. Maybe you are saying something else here, but I trust you've tried starting the recovery without anything plugged in at all.
Unless you can get the recovery working, the only hope you have is somehow levering up what you have available to gain a privileged thread of execution. Obviously that's going to be pretty challenging.
good luck - you're going to need it.
PS: could you provide a URL to the *wrong* One X gapps download? I think the gapps bundle ships with system libraries - I want to peek at those libs to see if there are any hardcoded block device paths that might explain the queerness you observed. (I can't imagine why this would be the case, but...)

[Q] Fastboot/ADB/sideloading issues

I flashed a 4.4 stock rom on my 2012 32g N7, and unfortunately, didn't notice until too late that it was also overwriting my custom recovery with the stock. Also, in the flashing process I received an error while flashing GAPPS. When I first booted the tablet, everything was fine except for no GAPPS, but I figured it would be simple to just download an APK or two and load them - well, when I tried that with several play store APKs I got "cannot open file" error.
I have now resorted to ADB to "sideload" the apks (and a custom recovery) to the tablet. At first I had trouble with the drivers, but I have followed numerous tutorials and have a solid grasp of how ADB works now. (more on that later)
I also tried WUG's toolkit, but no matter what I tried (or how many drivers I un/installed) I could never get past the "no fastboot device" error.
I used a second version of the ADB from another XDA thread, and was finally able to get my PC at the command prompt to communicate with the N7, and recognize it with "ADB devices" - the result was "<serial> sideload". This is of course when I have the tablet in the stock recovery "adb sideload" mode.
I about yelled for joy, when after six hours of rebooting and tutorials, I was able to get "adb sideload update.zip" to load, but the joy was short lived - as it consistently hangs at "sending: 'sideload' 53%"
I have tried several different zips, of varying names. and even some APK's (which hang at 78%)
Any assistance which can be offered to get this N7 functional again would be greatly appreciated!

If you're flashing the stock KitKat, you shouldn't need to flash a separate gapps package. Aside from making sure you have UAC control, make sure you update boot to 4.23, if you haven't already done so. Flashing 4.4 is easy, as long as you don't make the mistake of ever owning another An droid device and plugging it in to your pc... Dealing with missing/conflicting Windows drivers might require a vacation day and a fist-full of xanax,

LG G2 Fastboot

Everything I found on this says volume + and power, which kicks me into download mode, not fastboot.
I've gone into adb and typed adb reboot bootloader, but that just restarts the phone and turns in on like normal.
I google the how to enter fastboot mode on LG G2 and can find plenty of post about being stuck in fastboot, but nothing on how to get into fastboot in the first place.
Found a tutorial here about setting up and using fastboot and thought I was set until I got to the part about "and using fastback", where it just says:
Make sure you have android debugging turned on in your phone (not really needed for fastboot but you do need for ADB), plug it into your computer and boot into fastboot mode...
I felt like watching "Much ado about nothing" when Denzel says; "The learned constable is too cunning to be understood"
Any direction is appreciated.
Hmm, I may have written that guide... Just checked and yeah should have been more clear I'll change that up. It should have read the USB debugging was needed for adb (not for fastboot) so when you can issue
adb reboot bootloader
But after that I did mention to check device specific forum for answers on how to get into fastboot/bootloader and being I've never held an lg g2 I took a quick look around.
Unfortunately the only way that I found that people said works every time is to wipe recovery to get into bootloader mode as the recovery you guys currently have disables something due to a patch getting custom recoveries to work
So yeah, I would advice to speak with someone knowledgeable about your specific device before you just wipe recovery
Out of curiosity, is there something specific you need to do with fastboot or are you just curious about your phone?

the current thing I've been trying to straighten out is that despite being rooted and installing TWRP, I can't install ROMS. I tried CM 11 and Hellfire so that I could put kitkat on, but gave the following:
Error executing updater binary zip.
One of the answers I found said that I had to go back to TWRP 2.3 (I'm using 2.6) and I believe that's where the whole bootloader thing came into play, because it was the way to 'downgrade' -
So then I found Philz touch 6 (as I understand it a mode of CM 11), but here he talked about fastboot and lokifying items. Here's the link:
http://forum.xda-developers.com/showthread.php?t=2554053
In the end it still comes back to the "can't load ROMs" issue. Just want a completely stripped down Kitkat that I can add the stuff I want without the bloatware.
Thanks in advance.(and the thanks button was hit on your reply)
For KitKat you should need a newer recovery with SELinux support which I believe is 2.6.x and newer for twrp, 2.3 I doubt would work if there even is one for your phone
But yes fastboot is often the best way to change recoveries but not the only way.
If there is a flashable.zip you could install new recovery from old
If your current ROM supports the flash image binary you can use a terminal emulator
You can use adb to install
Or even apps from the market
I would look for the latest recovery for your device, twrp, cwm, shouldn't matter so long as its new and then find what way works best changing for your phone.
The update-binary issue is often a sign that you need to change recoveries
Unfortunately without having your device I don't know if I can give you the best answers but feel free to ask
Best of luck!

Thanks again. I have adb and the script for loading TWRP 2.6.xx. I unrooted and rerooted the phone, because I wasn't sure how to replace the recovery... Now I think I realize that I could just find another recovery image and place it in the same file as the loki flash and that will flash it (At least that's what I understand at present).
If that's the case, then downloading the Philz touch 6 would work... but not wanting to brick it, I'm still asking and reading.
Hello Guys.
I am having a similar issue. I have a new ROM that will not run because of a faulty lg set up wizard that always force closes and I can not get passed it and a nandroid that for some reason is corrupted. So. This fastboot seems to be a dead end it looks like a quick learning curve of ADB is the only viable answer. I have installed all SDK Manager with ADB Tools and also the required Jarva JDK and LG drivers. The phone is turned on (at the beginning of the faulty setup wizard) In CMD my device is found when typing in 'adb devices' So. I am already to push a new ROM over to the phone.
Do either of you guys know the adb command?
Help would be appreciated.
Thanks
You can't actually flash a new ROM with adb, but you can either push it phone with adb and then flash in recovery. Or if your recovery has an option for adb sideload then use this.
Also setup wizard crashing is usually the fault of wrong gapps or not wiping before flashing a rom

I found that the best way was to load flashify, that did the trick so I could start trying out ROMs... so no on to the next step - finding a 4.4.2 stripped down stock and the LG stuff I actually like.... thanks again.

I know it's not possible to flash a ROM via ADB. I have everything set up, ADB etc, etc. My phone is turned on and adb is seeing it but I can not work out the command to push. Every time I try to push I just get a long list of ADB instructions (I think they are) but nothing gets pushed. I have read lots of instructions on how to make the command but I still must be doing something wrong.
Here are my parameters;-
adb push/C:\Users\dene\Desktop/cm-11-20140210-SNAPSHOT-M3-d802.zip/sdcard
Am I missing some spaces I am not aware of? Are all my slashes the right way round and in the right places? Is my 'sdcard' destination designation correct seeing as there is only internal storage on the G2?
Another problem I am having is that ADB has no problem seeing my sevice EXCEPT when I boot in to recovery (TWRP). When in recovery I lose coms between my device and pc. Hence I can no do TWRP ADB side load (I have tried). I have all the correct LG drivers loaded. Except MTP keeps failing to install? Any ideas?
Not to be mardy about it or hassle you but I am fairly house bound and live out in the country and really require my mobile phone. I have spent many hours trying to figure this out. Any help with the above would be much appreciated?
PS. I did a very thorough wipe, I always do. The gapps are built in to this ROM!
Thanks

You need a space after push
But it usually easier not to enter the location of a file while pushing so cd to the directory first like
cd C:\Users.....
Then once there adb push /nameoffile /locationonphone
But if you don't want to cd, I see you have widows, depending on version you can just right click in the folder your file is located and choose open cmd here

As I thought I bought LG G2 D-802, but it was D-800 and I accidentally install the lollipop of D802 and now it's in bootlap.... I can only get into fastboot and whenever I try to flash .img of D-800 or D-802 it just stuck at "writing .img"
What to do to unbrick the phone and bring it back to live. I tired the adb and fastboot cmd method on windows 10 and windows 7 but no success. It's just stuck at writing .img file.

[Q] Tmobile D801 will not boot FIXED

Just switched over to Tmobile from Sprint and before even signing into google i went ahead and tried to root my phone. Rooting was a success. Used Flashify to flash twrp recovery. Downloaded rooted stock D80110G rom and began debloating it (like I did with the Sprint version) and then booted to recovery, wiped twice, flashed and reboot. Well, now it will just keep rebooting back to recovery and thats it!
I still have access to download mode
still have access to custom recovery
Did not do a nand backup unfortunately
cant mount in twrp because computer no longer recognizes phone!
shows up under unknown devices as LG D801
Tried the stock recovery using LG Flash tool posted in generals but ran into the "can not update because of your device policy" or something like that. Reinstalled and tried it again many times, even switching languages and countries (the last step)
Tried using the ubuntu method posted by partager.info but even ubuntu does not recognize the device. Matter of fact nothing even happens when i plug the phone in.
Tried reinstalling drivers, tried on 2 different laptops (one windows 8.1, one windows 7, and an ubuntu usb boot) and my desktop computer (windows 8.1) and am just unable to mount using twrp because none of them recognizes it!
tried using the adb sideload but twrp just stays trying to load adb sideload forever and adb terminal cant even find the connected usb device.
Tried factory reset but that just takes me to twrp.
I've redownloaded the rooted stock rom and left everything as is. I'm assuming I just need to get it onto the phone somehow so I can flash it.
I have an otg cable but not quite sure how to work it wit twrp or if that's even an option; I've just purchased it.
I feel like I've exhausted my options. Anything else I can try?
Thanks in advance.
EDIT: Should've just used Titanium to debloat instead of trying to do a fresh install! I know I know
Figured it out! not sure how to delete this thread now

I've redownloaded the rooted stock rom and left everything as is. I'm assuming I just need to get it onto the phone somehow so I can flash it.
I have an otg cable but not quite sure how to work it wit twrp or if that's even an option; I've just purchased it.
I feel like I've exhausted my options. Anything else I can try?
Thanks in advance.
EDIT: Should've just used Titanium to debloat instead of trying to do a fresh install! I know I know
Figured it out! not sure how to delete this thread now

Hey sorry, I haven't been on the site for a couple days.
I used the flashtool to go back to stock. Had to enter download mode and work from there. The big issue I was having was a driver issue. Uninstalled every driver related to android and then reinstalled after a restart and that did the trick. For some reason android phones are giving me a lot of driver issues on windows 8.1
follow these steps here but make sure you read a chunk of the thread as the steps in the main post are not complete

Help! Boot loop

Hi, I have a fully stock nexus 7 1st gen which is stuck on a boot loop, I am able to get it into fast boot mode where I've tried the wipe data/factory reset and wipe cache partition but it just freezes. I've searched around for solutions I've even tried flashing the stock images with wugfresh toolkit with no luck, most fixes it seems need the debugging enabled on the device which I can't do because I can't get into the menu. If anyone can help me it would be fantastic

Hey Mike, it sounds like you have no other option than to restore back to factory using the official Google Factory Images. That will completely wipe your N7, SDCard and all
Go ahead and download the nakasi image of your choice from Google: https://developers.google.com/android/nexus/images#nakasi... make sure that you don't accidentally get the nakasig firmware as it is for the Tilapia 3G model.
Extract it with 7-zip or WinRar (or whatever) and with your tablet plugged in and in Fastboot Mode, (you will also need the fastboot/ADB drivers installed) run the flash-all.bat batch file. (You may need to enable the Windows function "Show File Extensions" to see the .bat part after the file name. There is also a flash-all.sh in the folder as well but that one is for Linux users so you wont be able to use it unless you're on Linux.
Good Luck! :good:
Hi Tim, Thanks for replying,
I'm not too worried about losing data I'm just desperate to get it working again.
I have downloaded the flash image but where would I find the download for the fast boot drivers?

They should be included in the Wugfresh Toolkit that you downloaded. Just follow the steps to install the device drivers and I believe that the Fastboot drivers installs with it.
How weird, I am fixing my Dad's tonight, exact same issue! Have had it a week or so but just found time to do it now... I will do with you if you like. I already downloaded the wugfresh NRT and worked through the steps, obviously missing out the debug mode parts. Currently downloading the nakasi kot49h which is taking a while, so came on here to see what to do if this fails and saw your post!

If you download the nexus root kit v1.8.2 from www.wugfresh.com follow the steps on there to uninstall various drivers, then click the initial setup - full driver installation to get the correct driver for your device.

In the wug toolkit when installing drivers step by step guide to configure MTP drivers you need to disable USB debugging then disable MTP mode then re enable debugging all of which I can't do because I can't get into the menu to do anything
Hi Tom,
I can't seem to figure it out ive tried the wug toolkit a number of time with no results it seems most fixes need you to be able to enable debugging, if you find out how to do it let me know and if I by some miracle get it working I'll let you know
I have just run the flash stock and unroot option on wugfresh in the log everything has been erased but when it has tried to send bootloader is says failed<remote: bootloader is locked.>
Yes, you are up to where I got to. I fixed mine last night eventually. Next I tried a risky extra step which I won't tell as I don't think it did anything, then directly on the left of Flash and unroot there is a button to unlock bootloader. Run that, it gave me an error message but appeared to do the trick because the next time I ran flash + unroot it worked finally. Let us know how you get on!

No it still isn't working everything I try doesn't work it all comes down to the locked bootloader and no matter what I do I can't find a solution to open it
Has anyone come across the same problem and found a solution?

Open a command prompt in the folder with Fastboot. Type in "fastboot oem unlock" without quotes. That will unlock the bootloader and also you to flash factory image.
Doesn't work I've tried it before it just comes up with unlock bootloader screen where you have a choice yes (may void warranty) or no I click yes then I am directed back to fastboot mode with a message at the top left corner saying unlocking now....... but nothing ever happens, I restart device and I'm back to where I started.
Someone must know how to fix this
