Hey got my transformer today but no joy, It wont even power on . I charged it via wall socket for an hour, still wont power on so I tried charging it through usb on my desktop and still no dice. I tried the button combinations listed here http://forum.xda-developers.com/showthread.php?t=1032374 and was able to get a reproducible click noise but no screen movement what so ever. I unplugged it once in the beginning and it made a low battery noise but have not been able to make that happen again. Any ideas?
Thanks

P.S. Should I try this? http://tabletroms.com/forums/showthread.php?976-Nvflash-Unbricking-and-forever-root!
It couldn't hurt to try. It supposed to unbrick bricks.

Tried it. Windows does not recognize the device. Then clicking on properties it states that the device is not working. I'm guessing faulty cable. Will look for a replacement tonight.
As per the instructions charge it for 8 hours with the OEM charger and cable. Charging via the USB is pretty worthless. The charger is rated at 1.2 Amps at 15 volts. A USB port is .5 Amps at 5 volts, way less.
You need to install the Windows drivers to have ir recognized.
Sounds like a dead screen.
Does the power adapter feels hot/warm when you do your charging? Did you push in the power adapter until you hear a click sound?
@greeny2010 Yes and yes,
I will let it charge all night tonight and let you all know in the morning.
Ok I let it charge overnight and attempted to power it on. First I pressed the power button for ~10 seconds then waited ~5 seconds and pressed power again. This time the speakers made a pop noise and I heard the camera click but still no screen D:
Any other ideas? I really don't want to rma I have my final essay due Thursday and I stupidly sold my laptop to get this thinking it would get here and just work.
I read in another post where someone had a similar issue which was due to a bent pin where the transformer connects. I would inspect that carefully.

Within 30 days you can always return it, if you can find another one in stock somewhere. Otherwise RMA is your only option
bricked transformer
i have asus tranfrormer 9.x.x.x, recovery 5.8.x.x, after i did superwipe , every thing is gone and i cant flash any rom through adb/nvflash saying cant write to sdcard (read only). any suggestions?
so first and foremost, i did some searching, but I will not act as if I dug around the ENTIRE forum, so apologies in advance if I over looked/didnt find the needed help I am about to ask for.
That said.....we got my son a nexus 7 a while back and it is perfect....none of the issues some users have it has just been great......then my son screwed up the charging port by forcing his charger into in...yes he was given a stern talking to and a tutorial on how to properly charge electronics...no worries though I'll order him the dock.
Got the dock and now the Nexus 7 just screen flickers......
so to recap:
1)cant charge via port
2)dock causes Nexus to just screen flicker
what I've tried:
1)it sat on the dock for 24 hours - no dice
2) held power button down for 60 secs - no dice
3) tried every combination of Vol +/- & Power possible (for up to 60 secs) - there is a pattern developing
4)removed back and did a batt unplug/replug and then repeated the above 3 things - still no dice
(oh and yes I tried 1-3 both while it was docked and undocked)
I'm sure that it doesn't help that I cant be wired.....so I ask you the wonderful community.....any thoughts?
also it is a stock never rooted nexus 7.
Thank you in advance!!
I think if the dock port is okay than your son shorted the USB when forced the port. Now it's not charging because of shorted circuit. What you can do is to change the USB port or just remove it and use the dock.
It sounds like a short. The display flickers while on the dock, but is it able to charge at least?

It is able to charge.....I was able to fix it with really just some old fashion patience. I unplugged the batt again overnight and plugged it back in in the morning, and now it works like a charm.....
Thanks for the feedback guys.
I have ordered a new port to solder on, but to be frank, I dont think I'll do it unless i have too.
Hi guys,
My Nexus 7 (2012) turned off(not properly) when the battery level was low and won't power on. I tried a battery from a working tablet and tested my battery in another tablet. It seems like the issue is somewhere else.
These are the things I tried:
- leave it for a couple of hours charging (no battery sign at all)
- hold the power button with/without the volume levels while it being both connected and disconnected.
- tested my battery in another tabled and put a fully charged battery from another tablet
- made sure that the battery is connected
There was one more thing I tried - to press the Power button with no battery inside but the tablet being connected to a laptop via the USB cable. One could hear something like a boot noise coming from the tablet (doesn't happen when the battery is inside)
In December, 2015 I installed a Custom ROM with android 5.1.1 which I found here http://forum.xda-developers.com/nexus-7/development/android-6-aosp-grouper-t3268172/ (the thread was renamed and is now about the Android 6 update) The tablet worked fine for these 3 months but one day when I was checking my email it went off and won't respond to any actions.
Could you please help me to fix it? I'm just not ready to give up on this tablet. Thanks!
Both you and i, same model, essentially, the same circumstances. I also tried every method you mentioned as well. Even down to the flashing of a rom. Same results. I even tried "jump starting" the battery. Not wanting to give up on it. It sits in my closet like that boy in A.I at the bottom of the ocean, waiting... I know that is not the reply or help you were looking for. Just so you know, you are not alone..

Well, that's a good start, at least I am not the only one!
Have you tried to connect your device via USB? My laptop can see a connected device but it can't recognize it and I hear some sounds coming from the tablet when I try to hold the `power` button. This made me think that it can be a display/screen related, so the device works but we can't see it due to the broken screen/display. Don't know how to check that though.
Same here, stock Nexus 7, won't turn on, just switched off one day and won't come back on, have tried everything as suggested above, can't get it to flicker, doesn't even register the power connection with a green light or anything

Try replacing the screen, just to check. If that doesn't fix it, at least you have a brand new screen!
I'm currently having the same issue, haven't used it in 6 months and when I tried to turn it on, nothing happens

I fix mine,
let it sit on the charger for a hour, then hold down the button for 20 sec
same issue here as well ive had it for about a year and im not able to access anything via my pc google help forums had no answer either, looks like we may be screwed..........
Hi, I just had same issue with my tablet only thing is that I was using it with ~20% of battery, nothing special - browsing the web using chrome, then the screen lit gray and shut off. After that no response either from charger, holding power button for 60+ seconds didn't work either, tried re-connecting the battery, still with no signs.
And then, I tried to plug in the charger and then pressing VolumeDown+Power immediately after connecting the charger. Suddenly got some response, that battery charging icon appeared, and it shows my battery charging, but from 0%. Still waiting to charge a bit until I can try to boot it.
I'll update this post with any news.
EDIT: When I connected my tablet to the charger it had that hissing sound, but after few minutes it stopped.
After 15 minutes of charging I managed to boot my Nexus7 with 7% of charge in it a that moment, It seems to work for now.
Summarry of what I did to solve my problem:
1. Opened the back of the N7 (I used a guitar pick for this) and re-connect the battery.
2. Then plugged in the charger and at the same time pressed VolumeDown+Power, battery icon lit up but went out, repeated step 1, and then step 2 again gave me animated battery charging animation which showed up for like 10 seconds
3. Waited for 10-15 minutes and tried to boot normally. And it works now

Honestly, I do not think it is the battery, I can see the Charge signal, and the Battery is showing 1,784 VDC tested unplugged and disconnected, my smart young co-worker seems to think POST is failing, I still never see a "Charging" indication.
Does anyone know , Is there a fail safe, say the battery is disconnected, and usb charger is plugged in, will i just see all 5VDC at the sub port, ?
I never see a screen flicker, DEAD battery sign, nothing.
co-worker, tried some things that made sense when he explained what he did, I would have to agree with him.
Now it is rooted, 4.x something I forget, Never went to 5.x did once early and did not like it, Back stock, ran 2 days no issues, Rooted again, 4.x still do not remember, worked great 3-4 months, Sons ran it to DEaD and that was it, put it up for 90 days or so, wife got new tablet, kids have Fire each, and here i am tabletless, CRAP, did not want to throw to much $$$$ at this thing, nor did I want to buy a new one.
Samsung Tablet here we come.
any body want this Nexus 7, it is a 2012 model.

I would be more than happy to take it off of your hands mate. Probably gonna use it for parts to keep mine running.
My Nexus 7 2012 suddenly died, trying to use after a long time. It was stuck at loading so I wiped cache and it booted fine was very slow and sort of felt stuck so I rebooted and it never powered on again. It doesnt even show charging battery sign when plugged in. I tried everything nothing worked.
1) Pushed the power button for a minute and combination of other buttons as well
2) Left the battery for charging for hours at least 24 hours
3 Tried charging battery manually by removing it (like mentioned in many youtube videos etc)
I thought battery died but if I connect a small bulb to the battery it works fine, so I do not think battery is dead. What should I do? PC doesnt recognize it but if I plug it in the PC usb port and try to power on the tablet it does make a sound when something is connected to the PC but nothing shows up and it never charges.
What do you think it is? How should I fix this?
anyone?
I think the motherboard has died. The solution is a motherboard replacement.
I was given a Nexus 7 (2012) that had the same problem. The procedure in this video fixed it. Take note that there are two cells in the battery, two red wires and two black wires, you need to charge both cells. I made up a double lead and charged them both at the same time from a Samsung 1.0 amp charger, no problems. The unit now charges to 100% and works fine.
Forum wouldn't let me post a link. Search youtube for "Nexus 7 dead" and check the video by Doug Peng. Worked like a charm for me.

Hi, mannesty...
I've found this link...
...but here, Doug Peng talks about the Nexus 7 2013 model, the successor to the original Nexus 7 2012, so I'm dubious how much of what he says can be applied to the OP's original 1st generation Nexus 7.
----------------------------------
My view, is that I think the OP's device is hardbricked, with a corrupted or erased bootloader.
From his/her more recent post...
https://forum.xda-developers.com/nexus-7/help/figured-reviving-nexus-7-blob-files-t3983203
This is also highly suggestive of it too...

The charging battery animation, with the device in a powered off state, is part of the bootloader. It's failure to appear strongly suggests the bootloader is corrupted/overwritten/erased and the device thereby hardbricked, and the only tenable solution is a motherboard replacement, as a previous poster here has suggested.
Having said all of that though, it couldn't hurt to have a tinker around with the battery ~ and maybe Doug Peng might have something useful that just might work.

Ged.
