Hi

My sons 7" Android tablet (Nexus 7 mk2) has developed a fault.

When switched on it just shows a black screen with:

1. The green android robot on its back, with belly cover open and a red warning triangle with an exclamation mark inside

2. And the words below it "NO COMMAND"

I have Google It and everyone says it needs a HARD RESET to factory settings.

I done that

And WIPED ALL DATA

And WIPED ALL PARTITIONS

But when reboot again its not fixed it (same robot and NO COMMAND) :( :( :(

Does anyone have any other suggestions?

Thanks!

That's stuck in recovery mode, did it download the 6.0 update recently and fail to apply it?

 

What I would do is reflash it with the factory image from Google's Android developer page - however, that's not as easy as it sounds as there are drivers etc to set up first which aren't trivial. It doesn't sound like anything unrecoverable, just that you might have to go one step further than just a reset and actually "reinstall" the tablet.

It is probably recoverable, by downloading the correct ROM file and installing it, but you are probably best asking someone who knows to do it for you. I've not ROM'ed a Nexus, but I have done it to several other Android tablets and phones.

Yup, it's a re-flash ROM job.

Download and use wugs toolkit to make it easy and load 6 straight on.

Any step by steps, Martin?

Is it just a case of download onto PC and connect to tablet?

If can't even boot tablet how will PC recognise?

Thanks

The Nexus is probably one of the easiest I've ever done. However, that's easiEST, relative, I still wouldn't say it's actually easy.

You should be able to boot the tablet up (from off) while holding down the volume down button (or maybe the volume up button, I can't remember which). You should get to a screen with some small text in the bottom left, a green Android (which may have its cover open), and a menu roughly where the volume buttons are located. Once you've got this, you're in bootloader mode, and there's a second driver which causes your PC to recognise an Android device in bootloader mode ready for the command line tools or this "wugs toolkit" to be able to reinstall the OS.

 

If it's a Nexus 7 Mk2, I'm assuming you mean it's the 2013 model, in which case you need one of the following two links downloaded:

https://dl.google.com/dl/android/aosp/razor-mra58u-factory-0a88a925.tgz - Android 6.0, WiFi-only

https://dl.google.com/dl/android/aosp/razorg-mra58k-factory-7221a6d9.tgz - Android 6.0, WiFi+3G

 

Once you've got the archive file, hopefully there's an easy way to flash it using wugs toolkit, I've never actually used it myself...

Yeah, they're fairly big, but it's everything you should need to recover from a "soft-bricked" tablet. As long as you can get into the bootloader, then this should be able to put any other damage right (excluding hardware faults)...

I 'll give it another go later ....as it was too slow to download earlier....

Now works on my desktop. Must have been a site problem.

I've rooted a couple of nexus 7's. As said the easiest way is to use a "one click" toolkit. I've used the mskip toolkit which is pretty good.

I'm sure you need to enable usb debugging first though, which you can't since it won't turn on. I could be wrong, it's been a couple of years since I've done one.

Your laptop was probably too busy downloading Win10

Struggling to find how to start the application :( :( :(

 

Files uncompressed from .TGZ:

Problems here too :( :( :(

 

It seems to need to reboot THEN it can be set in DEVELOPER MODE! 

But THATS my problem, it dosen't boot proper :( :( :(

 

 

 

 

1. Initial problem, it boots to this:

 

 

 

 

2.So ran WUGFRESH...

 

 

3. selected UNLOCK (which reboots the tablet to enable the DEVELOPER OPTIONS):

 

4. My laptop recognises the tablet, it reboots ok....

 

 

5. BUT, it reboot to this screen now (SAME as original problem but, WITHOUT the "No Command" underneath now)

 - Which also means I cannot set the DEVELOPER OPTION        :(

 

 

Any advice?

I would ignore the Unlock option - I'm 99% sure that you don't need the bootloader unlocked to reflash the stock software (which is what you're trying to do). Based on your screenshots, what I would do is:

 

Turn the tablet off

Hold down the volume down button

Push the power button (keep holding vol down)

You should get to a screen that looks like this https://goo.gl/photos/BBhR3ra8VrERk7LX9

This is "fastboot mode"

 

In the toolkit window, under "Restore/Upgrade/Downgrade" tick the "softbricked" option

Click the "Flash Stock and unroot" button

I think at this point, it should ask you for the file to flash, at which point you give it whichever large file you downloaded from Google before (make sure you have the right one, WiFi-only vs. WiFi+3G)

You don't see much happening on the tablet screen during the flash, but I would imagine once it's finished the toolkit will tell you, and the tablet may reboot

Once it reboots, it *should* be up and running on Android 6.0

Thanks to everyone on here for help!

Gac's ""Restore/Upgrade/Downgrade" tick the "softbricked" option" using Gadgetman's download - sorted it!

So, special thanks Gac and Gadgetman
