my dad just bought two nexus 7's.. One for me ;)

The problem is that one of them was already opened, (they said that they were going to put it out for display) but he bought the last two they had..

So the one booted up perfectly...

The one that was already opened, he said it boots up to the welcome screen but it gives him an error message (no connection) and he it's like the touch screen isn't responding...

He lives several hours from me, and I've never touched a nexus 7, but I got him to boot it using the 3 finger method, and when he tried to go into recovery it just stayed at the Google Logo..

I'm trying to get him to do a factory reset..

I don't know if someone has borked it or what?

Any suggestions before he takes it back?

I know if i had my hands on it I could use fastboot etc.. but i don't want to void the warranty since he can return it and get a new one..

Thanks

Had to return to stock today after my nexus 7 was hanging at the Google startup screen. Thanks for the great write up chris.wueste

[Nexus 7 Android Development] Shano56:
I've actually never seen stock recovery...is there factory reset option in there? Try having him do it while its plugged into the computer. Maybe the wall
[Nexus 7 Android Development] okantomi:
Can you get into your CWM recovery via hardware keys? I'm definately stuck in a bootloop after rooting, then flashing new rom and gapps. I didn't wipe, cause I figured that unlocking wiped everything...dang, I never learn.
[Nexus 7 Android Development] elijahblake:
well, i followed this guide to flash it back to stock image (which it was anyway) and it still hangs at the Welcome screen, the notification pulldown keeps jumping up and down and sometimes it won't even work... I'm guessing it's a hardware defect..... Going to have him return it...
[Nexus 7 Android Development] spences10:
If you can get into the bootloader from holding down the Vol Up + Vol Down + Power keys then you can select recovery from there by using the volume rocker to select 'recovery mode'

Yeah, maybe try another rom first if its consistent then I'd have to agree with you

Bad USB connector

Ok I have an RMA for my Nexus 7 for a bad USB connector and I need to return to stock. Whats the best way to do this. I unlocked and rooted with WugFress Toolkit 1.52. I belive I should be able to reflash a stock image thru CWM. But how do I relock the device. Or since it is a hardware issue should I just do a factory reset and send it back as is. I dont need to get into a recovery boot loop with no USB port to ADB or fastboot into. Thanks
[Nexus 7 Android Development] Atmazzz:
Use the Tool Kit and you can flash back to stock and relock it. I've done it once. Very easy and painless.
[Nexus 7 Android Development] jnot2:
I can not use the toolkit because I have a bad USB port on the Nexus so I can not connect to my computer.
[Nexus 7 Android Development] Atmazzz:
Ah .. it would help if I could read.

There may be some way to do it through Terminal Emulator but I don't know. If you can't lock it I'm not sure it would matter. That's not the reason you have a bad USB port.
[Nexus 7 Android Development] caseyc:
So true, but ASUS is very firm about their warranty policy as I've experienced. If it goes to them with an unlocked bootloader, they're likely to call your warranty void and charge for the repairs...

Of course, with this being a Nexus 7 it may be a different outcome, but this was my experience with a defective screen on my transformer prime. Declined a $300 repair.
[Nexus 7 Android Development] methslushee:
honestly your best bet is to try and reboot and plug the cable into it right away when it boots up to see if its recognized, people have gotten there ports working again this way no matter how menial and annoying it is, your only other bet would mobile odin and to check around to see if any has experimented with it on the neuxs 7, but most likely that is a dead end since its not samsung
[Nexus 7 Android Development] slickie88:
Yeah, I'm bricked...

I seem to have managed to brick mine and I'm really not sure how. I successfully rooted using the Nexus Root Toolkit, install and configured all of my apps then thought I'd take the opportunity to make a nandroid backup and bam, boot loop.

I can only access the bootloader, which allows me to attempt to flash back to stock, but this too results in boot loop. I've flashed the latest version of CMW that reveals that I can't mount /sdcard. I believe I'm looking at a partition problem and need some guidance on how to get this thing back to stock so that I can start over again.
[Nexus 7 Android Development] brianjr1:
Have you tried flashing back to stock using ADB commands? Or did you just attempt to use it through Wug's toolkit?

---------- Post added at 07:37 PM ---------- Previous post was at 07:32 PM ----------

Also, google released the stock images for the 4.1.1 build. Found here.
[Nexus 7 Android Development] Vocalshock:
Are you kidding me? This is crazy I was in a CWM bootloop and going crazy. It seemed like nobody knew what to do and no reply to any of my posts. I am kinda new at this so I did not think I could use adb because my device was in CWM and I could not get to bootloader. Well after following this thread I was able to get to bootloader using fastboot. I have use adb a little so I was able to get it going and now I am back up and running. Woot Woot! Thank you so very much!
[Nexus 7 Android Development] jozkam:
Something isnt right, at what point does the zip file come into it? I dont see it, the link from google site just has a tar file containing a 250mb file with no file association.

What do you do with that?
[Nexus 7 Android Development] shong84:
Thank you very much!
[Nexus 7 Android Development] AtropineNa:
hey is there another mirror for the image? =( nexus wont boot... not sure if its cause i copied back the old (stock) build.prop or something..

Edit: going here: https://developers.google.com/android/nexus/images#nakasijro03d hopin' it works
[Nexus 7 Android Development] chris.wueste:
Apparently you didn't read hard enough because the instructions to boot into the bootloader using the side keys are definitely in the OP. Have been from day one.
[Nexus 7 Android Development] chris.wueste:
Just updated the OP with the new link. Sorry that took me so long. Hope my guide is helping people.
[Nexus 7 Android Development] chris.wueste:
Just did some thread maintenance. I have updated the OP to reflect the new stock 4.1.1 image both in the download link and in the code sections. Hope this guide continues to help you. This is my first guide on XDA so the thanks I have been getting are really making my day. You guys are awesome.
[Nexus 7 Android Development] Werbs:
did you guys put the charger and cord back in the back when you return it? i would like to keep a second one just in case
[Nexus 7 Android Development] cybrnook:
Worked like a charm! Thanks for the adb commands and listing the hosted 4.1.1 image. Trust this much better than the all in one tools........
[Nexus 7 Android Development] AtropineNa:
Of course you would have to put the charger and cord back when you return it
[Nexus 7 Android Development] chris.wueste:
I can't ever get the all in one toolkits to do anything for me. Nothing against the devs in any way. I appreciate their hard work. But i just cant seem to make them work for me.
[Nexus 7 Android Development] snipestech:
I bricked my nexus after flashing a custom rom

Stays stuck at jellybean screen on paranoid android rom

I downloaded fast boot adb enter the command to flash stock while in fast boot mode and

Tablet does nothing

Any help would be greatly appreciated

Btw I'm running w7

In the past I've been able to bring back android devices on a Linux box anybody know a tutoríal

Tx
[Nexus 7 Android Development] chris.wueste:
Have you put the tablet in fastboot mode. It needs to be on the bootloader screen to accept fastboot commands. Feel free to pm me if you have any questions. I've also used g+ hangouts to get people back on track. Your choice. Also...I didn't know paranoid had a rom for the nexus 7. Ive used their rom for the gnex several times and love it.
[Nexus 7 Android Development] wildestpixel:
Remember that the wipe is very complete so omit the -w in the update command if you want your sd card data in tact and perform a factory reset afterwards.
[Nexus 7 Android Development] toyfj2k7:
I wonder if this would work using a Mac if I extracted the zip to the root of the drive ( like you would when rooting anything) then changing the commands to ./fastboot-mac
[Nexus 7 Android Development] snipestech:
Yeah paranoid android is sick

Apparently I misunderstood and only did a dalvic caché wipe and that caused this and yes I am in fastboot mode

I also installed from, scratch on a laptop I have no go

Also tried through ubuntu still not recognized and yet my sg3 is recognized without a problem (3rd pc I've tried, switched out cables etc)

Tried wugz 1.5, nexus 7 toolkit adb etc
[Nexus 7 Android Development] jwedda:
I managed to brick my N7...

Strange, just did a system reset on a rooted JB 4.1.1. (I had been tinkering with the build-prop, but had restored it back to default.... I think .. )

I'm still on vacation, but upon returning I'll flash it using Adb. Txs for the video walkthrough!

While I'm mentally preparing to flash, I was wondering. The OP and the video both mention flashing the latest Google firmware. Is there a rooted firmware available with CWM? Makes it a lot easier and quicker

is it safe to install CWM or its recomended not to install ?

i dont have the time to mess again with reinstalling everything...

appriciate your answer !
[Nexus 7 Android Development] :
U can flash cwm and any rom u choose after. Or just cwm ..whatever you want. You're good.

Op: Tks! I used these images to come back from the dead.:D Really appreciate this!:thumbup:

[Nexus 7 Android Development] chris.wueste:

How long should "sending 'system' (438656 KB)..." take?

I left it for an hour last time but disconnected assuming it had hung.

Now I changed ports and It seemed to be running quicker but now I'm here again about 20 mins in.

The arrow keys to change the action on the power key are not responding, is that normal or the sign that the sending has stuck?

update: this ended in "FAILED (data transfer failure (Value too large for defined data type))"
[Nexus 7 Android Development] Surfy89:
When I'm flashing the stock image it says:

archive does not contain 'boot.sig'

archive does not contain 'recovery.img'

archive does not contain ' system.sig'

Then it write everything except SYSTEM. It says 'Sending 'syste' <438656 KB>... FAILED <remote: etc..'

What am I doing wrong?
[Nexus 7 Android Development] MaddMan420:
I'm having the same issues.
[Nexus 7 Android Development] thedauntlessone:
It's safe to install a custom recovery... that's how everyone installs their roms/kernels/mods.

I suggest you install TWRP 2.2.1 (2.2.1.4 is bugged and 2.2.1.5 is a beta release). I've always used CWM until I tried TWRP. Just better overall IMO.

---------- Post added at 08:20 PM ---------- Previous post was at 08:17 PM ----------

I received the same message about the archive. However, I did not receive a FAILED notice. I would redownload the factory image and try again.
[Nexus 7 Android Development] brando56894:
Wow unbricking the N7 is so much easier than unbricking the original Transformer, I hated NVflash with a passion, it was so damn confusing to use. If you're running linux it so much easier to unbrick the N7 because all you have to do is execute the shell script with root permissions and bam it's done for you!
[Nexus 7 Android Development] WiseManWhite:
This guide worked like a charm! I almost messed up and forgot to extract the file again after extracting it the first time.
[Nexus 7 Android Development] Shano56:
hah, thanks for this chris.wueste. I actually had to use this :P I flashed the first CM10 nightly (unbootable) and had no backup or other rom to revert to. I was also unable to push any roms to the device storage to flash, so this did the trick for me.
[Nexus 7 Android Development] Tibedabeeto:
Mine is doing the same thing, guess I will try to reboot from bootloader, see what happens. BTW it started off saying that the archive does not contain the 3 files mentioned earlier.

ONce I rebooted from bootloader the cmd screen showed failed, and it bootlooped once but afterwards booted up fine and is unrooted. I had to go back into bootloader to relock but now I am back to factory thanks, OP.
[Nexus 7 Android Development] gordo80:
How do I unroot with the newest version. I need to send my tablet for warranty since my screen is lifted. I try the unroot method but it can't push the file it gives me a message unable to locate file. Thanks
[Nexus 7 Android Development] nmlam:
excuse me, but after downloaded the factory image for the Nexus 7 & extracted to folder, i just had 1 file "nakasi-jro03d-factory-e102ba72", don't know where bootloader-grouper-3.34.img & image-nakasi-jro03d.zip, plz help me, i really need returning to stock, because my nexus 7 connect to wifi network, but there's no internet connection while my htc evo 3d & htc HD7 still using internet.
[Nexus 7 Android Development] clago87:
So it looks like I am having a problem getting into bootloader. I am stuck on the black google screen after trying to flash update of twrp. I cant get into recovery or bootloader and tablet won't turn off. Any advice out there? Getting a little worried now I am at full charge but can't get my computer to recognize the device.
[Nexus 7 Android Development] zekemo:
You need to extract the "nakasi-jro03d-factory-e102ba72" file with a program like winrar. The files you need are within the factory file.

Thank you!! You saved my a$$! I was in a slight panic mode after flashing the Beats=Xlouder killed my audio and I was stuck in a non-recoverable boot loop. Simple instructions and accurate. Perfect!
[Nexus 7 Android Development] chris.wueste:
Was this ever figured out? Did anyone ever get theirs running again?
[Nexus 7 Android Development] demandarin:
I haven't yet. I still need to try your manual method. I have similar issue. Using toolkit I get stuck on sending system or boot or recovery. It'll erase everything fine, reboot bootlaoader and write new bootloader to it. I detailed my situation in mskip roottloolkit thread. Just posted it a few minutes ago.

I installed android adk with platform tools and everything. But typing In "adb devices" in cmd shows me nothing after list of adb devices. Fastboot seems to work. At least partially. My device manager shows me connected as android adb device. So I believe I have all drivers properly installed. But I think toolkit wiped my device so I can't boot Into OS. So now I don't know if USB debugging is even enabled anymore. At least I can manually get into bootloader/fastboot mode.

Well I'm going to try your method shortly or maybe tomorrow. I've been at this for a few hours each last couple of days..lol. I'm determined to figure this out one way or another.

I'm wondering if i try to "Completely" wipe tablet clean. Meaning everything, data included, will that help..lol I'm afraid though. Don't want to wipe bootloader and not even be able to manually get I to it anymore. They say as long as i can get into fastboot/bootloader mode, I can recover. Somehow ;)
[Nexus 7 Android Development] demandarin:
Update: close but no cigar :(

I used this manual fastboot method. Used video for reference. Everything initally went well. Typed in commands and they were going through just like toolkit. Showing same things. I got all the way near the end to the part where its sending "system". It got stuck. I left it alone for half an hour and still no luck. It sent and wrote "boot" & "recovery" before that just fine. So seeing it was a bust I tried again. This time it got stuck on sending "boot". I give up for tonight..lmao. don't know why initial steps send and write just fine. Then when it comes to flashing/sending the system, it gets stuck. Doing the exact same thing that occurred with toolkits trying to reflash stock.

I've tried toolkit and now over tried manually with fastboot. Sending "system" is the farthest I've gotten trying to reflash stock. I need some help.

On a positive note, it felt good entering in fastboot commands ans seeing them perform just like the toolkit. Fastboot isn't hard at all. I just wish I could successfully reflash this device back to stock. If i end up not being able to, ill just try to relock the bootloader then and send it back in like that. Everything is erased so no proof of rooting or unlocking if i can at least relock it. Ill read up somemore and give it another shot tomorrow since I'm off. I really want to put this back to stock firmware. If i can't, ill try to relock bootloader and send it back as is. Its not my main N7. Its a replacement they sent me THST the speakers were really bad on them. So I'm sending it back to them. I had unlocked it though while I had it.
[Nexus 7 Android Development] Hussainally:
Yes .I managed to get to stock using adb.just ignore these errors.I unplug device reinstall drivers and immediately flashed the stock ROM and it worked.
[Nexus 7 Android Development] tonno16:
please help me, I hope to write in correct section. I use toolkit and everythis seems to work.

I rooted device, I unlock device but now after flashing a cwm touch recovery with toolkit 2.0 my n7 reboot on a black screen where the only two icons are the lock (unlocked lock) and the white word "Google"

I can remove the battery so What I can do?? please answer me.
[Nexus 7 Android Development] rkanwar:
Hi guys. Im trying to fastboot the image.zip file but.nothing is happening. It says archive does not contain boot.sig and recovery.sig

Edit. Ok now its advanced but now im stuck on sending 'boot' <4890 kb> its been twenty mins
[Nexus 7 Android Development] demandarin:
I had exact same issue. Or sometimes it would get past that but get stuck on sending system. I never got it solved. So I just relocked the tablet and sending it back to Google. It was a replacement unit anyways. My original unit works fine so ill be keeping it. But I do wish a solution can be found. I tried everything and it didn't work. I saw some new tool that completely wipes the nexus 7 and allows you to load recovery/bootloader from a fresh clean slate. THST might help. Bit for me, no matter if using root tool or manually fastbooting commands, tablet would get stuck on previous statement. I cleaned all drivers, reinstalled, tried different cables, different plugs, nothing worked. Only thing I wasn't able to try was doing it from another pc, because I don't have another one.

Good luck. If you fond solution, please post it up as we are not alone In this issue.

Flashing the "R" stock image will wipe everything & flash stock recovery right?

CWM works on the new binaries?

What i'm doing wrong? :(
[Nexus 7 Android Development] demandarin:
Did you make sure to put all those .img in same folder as your platform tools? But Iwould think it would say ccan't find it and not can't load it. Make sure your adb drivers installed correctly. You can also try typing "fastboot adb" to get adb going

Then "fastboot adb devices" to see if it lists your device.

Good luck getting it running. Hopefully someone else chhime in soon.
[Nexus 7 Android Development] Patroy:
i'm sure that files are in the same folder as platform tools, typing commands which you wrote didn't do anything. just schowing list of avaliable commands
[Nexus 7 Android Development] demandarin:
Do you have your adb pointed to the right folder/directory? It should be pointed to platform tools. Watch that YouTube video in op. It'll show you how to point it to your android sdk folder then to platform tools. Once file path properly set, you "should" be good. Doesn't look like your filepaths set correctly. THST YouTube video shows you step by step.
[Nexus 7 Android Development] Patroy:
I did it with toolkit and the toolkit just downloaded other named file and flashed it on his own. Now everything works very well, but thanks anyway :)
