Hi, NexusAd...
I generated my own Nexus 7 'blobs' some years ago, and fortunately, I've never had cause to use them. My Nexus 7's bootloader is still good, and the tablet still works, albeit very, very slowly (I blame Lollipop for that!) and which is why I rarely use it these days.
It has always seemed to me, that the 'flatline' procedure, for generating such 'blobs' and then using them to restore a Nexus 7's bootloader, was somewhat experimental and not guaranteed of success. I've never read of any successful attempts here on XDA or anywhere else for that matter, where somebody has actually used 'flatline blobs' to that effect.
----------------------------------------
So anyway... as I understand it, there's really only one way of reviving a hardbricked Nexus 7, and that's via a motherboard replacement.
Rgrds,
Ged.

Between a rock and a hard place...

Hello all,
I need some advice concerning my Nex4. As many people have experienced, I also have a slightly buzzing earpiece and now I'm in doubt whether to use my warranty and get a new one or not.
Since I live in Holland I got my Nex4 through someone else from a store in Germany, about 1 - 1,5 hours away to reach it if I want a new one. Since I'm 15 and not able to get there myself I'll probably will need to go through some quarreling with my parents to get them to driving me there.
The issue is that I'm not sure if I want to go through all those things, since the problem doesn't actually bother me. I can make good quality calls with a little of buzzing which I don't mind and I'm happy with my battery life: 3-4 hours of screen time on 1,5 days with medium usage.
I hope you can give me some counsel. Thanks in advance!
By the way, when I'm studying in silence I sometimes seem to be able to actually hear some high-pitched sounds, which I do mind, but I guess that's partially a placebo effect.

I just got a REV 11 device. it still makes the nose, albeit slightly quieter. With that said, these phones have build quality issues and getting a new one might be more hassle than it's worth. My REV 11 device has a slightly worse screen than my REV10 (lots of streaks on the the grey scale). Just keep that in mind.
Wait, REV 10 and 11? Did you already do this many RMAs or did I misunderstood the meaning of the word ^^?
Sent from my beloved Nexus 4
You misunderstand the word, REV is for hardware revision, a new revision comes with small changes. I got a REV 11 device and it's my first one.
Also keep in mind, you don't know if your replacement device is going to be any better.
Ah, thanks, any idea if I could check my REV?

Reboot into bootlader mode & it will tell your hardware rev.

There is no danger in booting into fastboot made & checking the info. IIRC with the phone off hold volue down & power at the same time.
Thanks, I've got REV 11. I guess I'll stick with it.

Awesome Wipe Script Bricked my Nexus 7

Hi all,
So I flashed the superwipe script made my "Awesome" and in the OP it said it wipes external so I assumed all was okay. well it wiped the internal entirely so now my nexus 7 is bricked. I can't even turn the ****ing thing off without runing the battery to dead.
What can I do now to get it back to at least stock ?
Nevermind..
I fixed everything by following this guide

Please do not use the term bricked when your tablet isn't actually bricked.

Which is the crux of the problem-throwing around terms without knowing what they mean. It's like someone with a cough assuming it's mesothelioma when it's really just the common cold.

I think that people tend to go into panic mode when something untoward happens... and the word BRICK in bright red letters flashes on and off in their mind, without really understanding the difference between hardbrick and softbrick.
People...
...if you see the word 'Google' upon boot - and nothing after (or maybe just the ROM boot-animation)... you're bootloader is still good and you're likely just softbricked/bootlooped or otherwise wedged.
If you DON'T see the word 'Google' upon boot... now is the time to start worrying - but don't panic, as that impairs judgement and clarity of thought.... both of which are needed in order to fix whatever ails your device.

I've thought I had a device bricked before, then realised it wasn't.
Doesn't mean I don't know what bricked is??

What should I do with my old Nexus 7?

I bought a new Nexus 7, returned it today due to screen problems, and ordered a new one from Best Buy that I should get tomorrow or Thursday.
I was wondering what you guys have done with your old Nexus 7 or any recommendations on what I should do with mine. Mine is 32GB and still perfectly functional. I was thinking about using it as a media server but I'm not sure how useful that would be. I'd rather not have it just sit here and collect dust.
Thanks ahead of time.
Sell it.

Why not using it with the daydream? An expensive alarm clock with weather notifications, along with some other stuff and as such it can also collect dust!

You could use it as a permanent car mount, or a clock, or a computer remote ( unified remote works great), or just sell it.

Try to impress a date and bring it with you on a boat, only to fall into the water (happened to me.)
But seriously,
1. Ebay if you want to sell it fast, tho you probably won't get as much as you want for it, plus ebay and paypal fees sting.
2. Craigslist if you want to risk getting robbed.
3. Give to niece/nephew if you have them as a christmas present.
4. Keep it and wait 20 years until it becomes a collectors item, then sell it for bookoo bucks!!
5. Learn to develop games/apps with it.
6. Use it as a coaster.

I only suggest using the old one to dev on just in case something goes completely wrong and it gets ruined. I don't know much about android development, so I don't know if its even possible to brick the N7, but just as a cautionary measure, I would rather use an older device than a brand new one JUST IN CASE.
In the same boat as you, have no clue about development, was just curious. But now that I too have an old nexus lying around maybe I'll look into it!

Oh, it's possible. Believe you me, you can do it. It's just a bit harder to kill a Nexus device in most situations.
I can confirm it makes a great coaster. I'm starting to lose interest in flashing new ROMs every few months, but I may repurpose my Nexus 7 into a HUD unit of sorts to mount over my desk.

Random Black Screen Flashes

I have owned a Nexus 7 2nd gen for a couple months now and have just started to get random flashes of black (occurs for not even a quarter second) ...
I am wondering what causes this...
I have not damaged the Nexus in any way and bought it brand new..
I have only used CleanRom and PA ROM...
The functionality of the tablet remains great, but the flashes are very annoying ...I have tried clean installing multiple times but the flashes still happen...
Any feedback/solutions would be a big help...
Thanks

I had that happen soon enough for a return to be viable. Do some more Google searching and you'll find people who fixed this as a hardware issue. They had to open the back and fiddle a connection. Didn't sound to hard but I just went to best buy instead.
Happy hunting, sorry I don't have a link.

Yea I would exchange it before it is too late. Doesn't seem that troublesome but if it got worse, or worst, disconnected entirely, it would bring bad news.

Just because you bought it off ebay doesn't mean it doesn't still carry the 1 year manufacturer warranty on the hardware. It would require you to send it in, but worth a shot.
Once you pop the back and start fiddling with hardware, you run the risk of doing enough damage where Asus will void the warranty. I think I would check with Asus first before resorting to hardware modifications.

[Q] Nexus 7 HardBricked

Hi, I was trying to update my nexus 7 from fastboot, one of the fastboot commands for the bootloader gave an error. So I tried to reboot and again same error, so stupid thing I did and I turned it off from the bootloader (when the device was still on). now the device is not responsive, it doesn't turn on or have any reaction. I'm familiar with unlocking bootloader and all the android stuff since the first day of android, so my nexus 7 doesn't have any bootloader in it anymore (at least not a proper bootloader. in the device manager when I plug it in, it shows as a device called APX. can anyone help me get turn it on. as far as it turns on I can handle to flash it with some code lines. but I have no idea how to bring a bricked nexus 7 to life.
and if it helps so far googling I ended up with a program called QPST. if anyone help me use it I think I can bring it to life
I'm even considering donating if anyone help me succeed, cause for one fact I know this device is not coming to life easily
welcome I have the same problem been looking everywhere. Have you got the 2013 because i think qpst is for qualcomm chipset
I have the old nexus 7, and I have tried even nvflash, I can communicate with my device through USB but I need someone who knows better to give me (us) the right files so I can push the data to the device, maybe search for nvflash or nexus 7 blob.bin file if you have never heard of it

I don't know about you but I'm taking a risk of detaching the memory part from the motherboard reprogram it with the boot data and re attach it to the board again. seems like a crazy idea but its better than another 300$ to buy a new one

I'm not that advanced. I downloaded the cardhu driver package directly from nvidia website which seems to have lots of interesting files including nvflash I don't know if you already seen but I used this to get my uid which never happened with anything else, maybe if looked at by someone with more knowledge can pick something important from there. I know someone who solved his problem since he had a blob.bin his post is on here aswell you could ask him and take a dig, I wouldn't know what to look for

I figured out how to fix it with blob.bin for own device, without my blob.bin I found a generator from acer tablets which generates your device encryption to use someone elses blob.bin using your UID, UID is a good choice. but if you've used costume roms before, there is 50% chance your UID have been modified from the original one. I don't know how it happens, but it did for me in past.
by the way you can read your original UID by just opening back of the nexus 7, its written inside the back of the tablet on the lower part near the speakers
So that means we just need an already made blob.bin. well getting a blob.bin won't be hard, I'll ask around since there are lots of people who backed up their blob.bin

Hi, mehras1991...
Here is my 'blob.bin' (and other associated files) that I generated some months ago, using the flatline procedure.
https://dl.dropboxusercontent.com/u/37483979/blob_bin.zip
The files in this .zip archive were generated from a WiFi only Nexus 7 2012 model.
Hope this helps... but to be honest, I'll be very surprised if it does... as bootloaders are crypto-signed to a specific Nexus 7.

Yeah, I was able to backup my own blob.bin using the instructions. Still doesn't help me with the bricked Nexus 7 though. Why do they need to make it so difficult? There should be a generic blob that would let u recover a device, or at least a utility to generate a valid blob file knowing only the devices's UID.

so if you have your own blob.bin what's the problem, you can easily recover it with nvflash, just incase your computer doesn't recognize the dead device, don't plug it to a USB 3, it just makes it harder for you to resolve it. when you plug the tablet doesn't turn on, but your computer see the usb port open. and don't leave the tablet pluged to laptop alot, since the tablet can't be charged at this stage, if it runs out of battery then you also have to replace a new battery to boot it up the first time.

Yeah maybe I wasn't clear. I have two Nexus 7s...my own which is fine and backed up bin files, and my friend's dead Nexus 7 which is a different tablet and I DON'T have the blob.bin for that one.
