I can't even boot up now..it sstays in the Google screen plz help me
UPDATE: I switched usb ports and it worked.... man urges the best....I love u....urge the best...I want to donate plz give me a link so that I can donate. Ur the best man.... love u and android central... android for life.....

Yeah usually switching to a rear usb port will help. Glad you got it working. Key thing is to not panic, you can't brick a Nexus device, we can always fix them.

No donations needed buddy, just enjoy :)

Re: [GUIDE] Factory Image Restore for your Nexus 7

THANKYOU SO SO SO MUCH!

After flashing ParanoidAndroid on my Nexus, I decided I didn't want it and wiped everything, but some of it was still there; the keyboard had some holes in it and there were only two options at the bottom; back and recent apps. From the home screen it was obvious that it went wrong. i must have wiped everything at least five times, until I started to get desperate. I found this after three hours of googling and it worked perfectly. I was a bit worried with all the erasing I had to do, but it was good. THANKYOU AGAIN!

Re: [GUIDE] Factory Image Restore for your Nexus 7

Hello i was wondering if any of you could help me. Im trying to do a factory reset of my tablet, its rooted and what i think i might have bricked it or w.e it never gets past the boot up from the fastbood mode even when i choose recovery or something. I followed the video to the dot and i get up to the part where im supposed to plug my tablet it in.. i plugged it in and still nothing.. it still says waiting for device. I've used 2 cables and still nothing. Any help will be nice.
Or i heard that theres another way to do a hard reset and thats by setting it into recovery from the fastboot mode but i heard that the nexus 7 has a bug and u need to be plugged into a pc to do it, problem is when i plug it into a pc i cant use the volume buttons. If any1 could tell me how to fix that problem then i can just do it that way. Sorry if im hijacking this thread lol.

Hi folks,first time poster on here but long time poster on XDA,basically like many on here my Nexus is not working due to a bad flash,tried twice using the Nexus 7 toolkit but it just stays at sending system so im gonna try manually input the commands,sold my laptop and just use the Nexus (and Galaxy S3) so using internet cafes.

Hopefully 3rd time lucky after work tomorrow evening,2defmouze looks to be very helpful and knowledgeable,fingers crossed ill get my Nexus 7 back,im lost without it.

You're right on that one. Finally, a device that is I.Guy-proof! :) takes a while to figure out what you're doing, but once you get it, it's all fun and games.

Keep trying.. If it worked before it will work again.

What keeps going on that you've had to do so many factory image restores, out of curiosity?

Try sending the pieces individually. First perform the wipe steps (fastboot erase boot, fastboot erase userdata, fastboot erase system, etc...), then send the bits one at a time:
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash recovery recovery.img
etc down the list...

Now its my turn! I have been at it for last 18 hours straight trying to wrap my head around.

Once upon a time, 18 hours ago....I was reading a book on N7 when it just went off. I thought the battery must have died. Left it on charge overnight. Turn it back on in the morning and get the "X"!
I have tried most suggestions in this post and from other posts too.
Long story short, I am able to get into "fastboot" mode.
I am able to get the serial number response from "fastboot devices".
I am NOT able to go any further (CANNOT get "fastboot oem unlock" to work which would be the key to this entire theatrics).
To save all a lot of reading, I am attaching image.
Any genius's out here who can trump the fat fallen Android?

Well a factory image restore is meant to recover your device when you screwed something up hacking at it. Yours just turning off while you're reading is not related. Sounds more like hardware failure to me, though I can't say for sure.

fastboot flash boot boot.img

it says that the device shuts down the end point...
gone to google...:(
