Nexus 7 Wont Boot - Android Q&A, Help & Troubleshooting

I have a 2012 Nexus 7 and it has a really weird problem, when it boots it goes to this screen and won't do anything if I click start. If I go to recovery mode, it says Booting Failed in the top left, it seems that android is removed, but I'm not sure. Sorry for bad picture quality

Looks like you will need to try and restore by flashing the original factory img files.
Guide: http://forum.xda-developers.com/showthread.php?t=1907796 (hint, skip all of the SDK stuff for adb and fastboot and just use this - http://forum.xda-developers.com/showthread.php?t=2317790) . Also, make sure to grab the same update or newer, for best results.
I prefer doing things manually as it is good to learn how things work, but if that is just above your expertise, you can also check this out: http://forum.xda-developers.com/showthread.php?t=1907796
Good luck.

Well, you either have a corrupted file or you didn't do something right. The best way to flash into or flash out of honeycomb rom is to follow my code red instructions found at my website in signature.

That was my original post. And I'm not getting any respond. I have a Moto x DE xt1053 unlocked bootloader and Rooted. I started flashing all sort off Roms and gapps. And the other day I was just browsing system files and I've seen the log . and I notice that my phone got really slower too. Boot logo shows but when its done it goes black screen for at least 5 sec and then goes to lock screen.

Those are the screenshot. As mentioned on my original post . the last image was from a website that sells mobile spy. And I even read a thread saying that it has something to do with rf-42 firmware bug.
I don't know and I'm kinda afraid to do anything with my phone . coz I'm still a noobie in flashing and I don't wanna break my phone.

Unable to flash device using FlashTool for Mac OS X

Hello,
I am attempting to flash my Sony Xperia M phone, to downgrade it from 4.3 to 4.1 (in order to install a custom ROM).
I have downloaded two versions of the 4.1 OS, but neither appear to work.
The problem is, the progress bar indicating how far along the Flashing process is, is stuck at one point forever.
As I understand, it should take only a matter of minutes, but I've left it going for hours at a time, but it never completes.
There seems to be something wrong with the software, or the OS I've downloaded, or the phone itself. I have no idea.
If you are able to suggest ways around this problem, that would be appreciated.
Here's a screenshot and a WebM of the Flashing process.

Asus C300 recovery

My ass c300 recently decided to boot up with the missing or damaged os message yesterday. Tried using the recovery utility on my PC to make a USB recovery but no luck, it just gets to "system restore in progress..." With the spinning wheel to the left and never advances. I made one USB with the downloaded image via utility, another via the only imagine download I could find online (it said it was outdated when tried that one and wouldn't let me go any further), tried my computer in safe mode with networking and same thing.
I'm at a stuck point n have no idea how to go about this further... Anyone have suggestions or maybe a updated recovery image for the c300? I use my Chromebook daily so need to fix this asap if possible.

You have erased/deleted your Boot partition. No need to worry tho. You will need to flash the stock rom or boot image using a computer. There are many tutorials out there for that.
Just like this one :
P.S. the device is different but the brand and problem are same, so you should have no problem.
