My son's Vega had Vegacream installed and was working fine until this afternoon, when it wouldn't turn back on, I could only get the backlight to show for a few seconds, then just a black screen. I had to hold the power button for 5 secs to reset it, only to get the same backlight for a few seconds then black screen.
I've made sure I had all the correct drivers installed using AUDI, and I can get the tablet into nvflash recovery no problem and reflash roms. I've tried reflashing vegacream, no difference, just backlight then black screen again. I've also tried reflashing vega moddedstock and original stock 1.10, it says they've flashed correctly in the dos window, but they just show the green android logo for a few seconds, then black screen again, and I have to hold power for 5 seconds to shut it down, then it just boots to the android logo again etc etc etc.
I know there are loads of posts already about Vegas that won't boot, and I've read lots of them , but I can't seem to find a solution to my problem.
Any help and advice would be greatly appreciated, my son is badgering me every 5 minutes, is my tablet fixed yet Dad?!

Need help/advice.
I flashed from stock rotos rom jme. I had problem with flashing. Things like windows not recognising tab in download mode. Several times failed flashing in midle of flash process. At the end I flashed succesfully. And things are working normaly. But when I switch off and then on. I get at&t logo and then black screen, i get sound from samsung logo but still black screen. Buttons on/off the backlight few times and still black screen. Then I press sleep then wake and i get straight the locking screen and all fine till next boot.
It looks like the boot part does not initialize the screen propely as its has a white line across when its black.
And in recovery i cant see what I am selecting.
Any ideas?
update:
sys73r pointed me to http://forum.xda-developers.com/showthread.php?t=899196. I will test that after I solve my unstable USB connection. As flasshing boot with usb problem smells like brick factory.
Sorry for bringing this again to top.
The fix was already posted.
Hello I am trying to fix a friend nexus 7 first gen
the problem is that it keeps flashing the white google logo like its boot looping , the system doesn't even seem to be restarting just a flash on flash off google logo , no nexus logo or anything else at all.
I cannot get into recovery it will just shutoff everytime i try even from the bootloader menu
tablet doesn't have debugging mode on so only thing I can do is work via fastboot
already tried to flash like 5 different versions of android and everytime it finish (succesfully) and goes to restart it just keep doing the same on the google screen.
any help is greatly appriciated, and I have been searching all around the internet for hours now and have seen many solutions to bootlooping which I have pratice before on many of my other android devices but nothing like this problem.
thank you and pardon my english.
When you turn on the tablet with the power button and the screen's backlit turns up, press the VolDown button. This way you can boot into bootloader and flash a factory image provided by Google.
yup like I said before I did got into bootloader and flashed factory stock images like 10 times now and still having the same problem, this is what i usually do when I get into bootloops with any other android device but for some reason this time is different.
its not idle at google and I dont even get to see the nexus logo it just shows the google logo for one second and screen goes black then again the google logo and black screen like infinite restarts with one second delay.
Then it maybe hardware related (corrupted nand/partition/etc) so you might consider to send it to Asus/Google to repair.
So this happened when I installed latest version of LOS14.1.
Basically happened to me 3 times, the screen won't turn on after I lock my phone, reboot doesn't help and there is no logo on boot. Black screen in recovery and download mode. I managed to enter download mode and installed stock firmware but the phone screen is still black.
When it first happened I managed to 'repair' the screen by pressing power button for some time. Second time it happened I got lucky again and screen turned on so I did factory reset. This time I can't do anything, I flashed the stock firmware and the screen is still black with blue LED on. I'm out of options and have no idea what to do, I am going to open my phone tomorrow to check if some cables loosened up.
Starting from the beginning: My phone crashed restarted several times and then black screen with blue led. Then I had t wait for the battery to die because none of the home power vol, power vol keys worked. Eventually got it into recovery mode selected wipe cache restarted same problem.
Now the phone even boot into recovery. It just stays on the blue screen saying "Installing system update" . The little recycling loading icon spins a couple times then its just stuck. Resorted to losing everything and installed smart switch and did emergency restore. Flashed a few times still no joy. Took it to shops they charged it turned it on and its reset to factory. Got it running again, only for it to go into a boot loop. Curious if it was actually fixed, i booted into recovery mode same issue and now back to square one. (I did let the battery die and started it up, came to the home screen and it started rebooting again to black screen and blue LED again.)
I do intend on sending it back but I am wondering could be that the recovery partition is corrupted?
Hello everyone,
So I have an Venku Android 10 PX6 unit that I had installed Hal9k onto some time ago, and for months everything worked fine.
However, about a week ago, the device got stuck on the boot logo and does not actually boot up android.
I have removed the power to the unit, pressing the buttons while its unplugged to drain any residual power, but that has done nothing. it just goes back to the boot logo once again.
The backup camera does work, but aside from that nothing else does. I do have the OEM FW on a flash drive, and I have tried to access recovery mode to flash it, but holding reset down doesnt seem to get me there. When I press down RST, the button lights turn off, as does the screen, but the button lights never flash indicating that I can release. I've tried holding it down for 15+ seconds, but no matter what, once I release it, the button lights come on like normal and so does the HAL9K boot image. It then just stays there.
At this point, I am thinking that this is a hardware failure, but I wanted to see if anyone had another creative way to get into recovery or something else I can try to get into recovery or reflash without recovery mode. I have looked at other posts, but couldnt find one that yielded any results.
Thank you all in advance.
Perhaps read MTCD forums and the detailed recovery / OTG posts
