Hi folks

Really hoping someone has an idea...or I've got an expensive paperweight in my lap.

Installed r4 just fine.  Installed Clockworkmod just fine and tested, including a nand backup.  Then install r5.  Had a complete brain fart and closed the cmd prompt before the Vega had rebooted, thought the job had finished but forgot to wait for the Vega.  

Now it won't boot but no problem because I've got the nandroid backup - ah, wait, no way to get to the Clockworkmod reboot app.  So, into recovery for a stock image flash but, and here's the big problem, I can't get into recovery.  Doing the usual and whilst holding down the back button after 2 secs try to hold the power button for 2 secs but as soon as I touch the power button, the backlight comes on.  Tried booting and getting to recovery with power plugged in and on battery only.

ADB doesn't see it either :-(

I'll have your babies if you've got an idea...

Cheers

Simon

PS Paul.  Just adding to the chorus of bloody good job....thank you.

Just keep trying. Try with and without power, try after leaving it a while, press a few other buttons then try again.

I've flashed bad images a good number of times and ended up in the same situation as you - you'll get into recovery in the end.

Tip: Open device manager on your Windows PC while you're trying to get into recovery, you'll see the list 'refresh' when it sees the recovery device arrive!

I had a similar problem a few days back and could not for the life of get it in to recovery. Tried constantly for an hour or so and got so p$%%$d off. Ended up leaving it for a bit and hitting the bottle to make me feel better and when I returned and hour later first try and bingo straight there so as Pauls says just keep trying and may a bottle of beer in-between lol.

[simonta]

You mean I got to drink beer to make this work?  Cooool.

Thanks guys, I'll leave it for tonight and see how it goes - fingers and thumbs are hurting after about 2 hours of trying :-)

Night all.

[ho66es]

good luck on your return!

I might have stumbled onto something.

Couldn't resist trying just a little bit longer so, beer in hand, I thought about booting into recovery.  Why hold the back button down first?  Why not just press back then press power?  I'm guessing that holding down the back button clears something in the nand.  Then pressing power with the back button held on kicks off the recovery boot script.  The script then checks for power release at 2 seconds then back down for 2 seconds.  Of course, I might be talking gibberish - but it has inspired me to try to figure out how the recovery boot mechanism works.

I've already got the beer so let's try more button combinations.  Here's what I found.  It could be a complete co-incidence but I thought I'd post anyway in case someone else gets into the same situation and this helps them.  I'm not particulary inclined to put myself in a pickle again so if someone else finds this works, please reply so others might benefit (actually, post if it doesn't, all good experience).

1. With the charger unplugged, hold the power button down for 6 seconds.
2.  Keep the back button held down and plug in the charger.  Wait for the blue led to illuminate.
3.  (from here, it's the normal recovery boot procedure). Hold the back button for 2 seconds.
4.  Keep the back button held down and press the power button for 2 seconds.
5.  Release the power button.
6.  Hold the back button for further 2 seconds then release it.  Voila!

Reflashed stock then nadroid restored and still got time to finish the beer...

Thanks to Paul and T4yor.

Night all.

I had a similar problem and left it on until the battery was flat and then tried again. Worked first time.
Best piece of advice I have us if the screen lights up its to late. Start again. Took me ages to work that out.

Does it require any specific brand of beer?

Nice work getting it fixed.  As we're allowed to run custom ROMs on the thing I'd imagine it wouldn't be too much of a problem to get the thing fixed if you hadn't got it working again.

Hi Guys

I pressed the  usb slave/host widget on my tablet and when my vega rebooted it said "booting", blinked," booting" again and then said "advent" then turned itself off. I have the R8 rom installed which has been working fine. I have tried all the various button pressing combination exercises mentioned in the threads (and at different times) to no avail. It is still doing the same thing. Where am I going wrong? Has someone produced a video tutorial on this.

[nowimboard]

Afternoon!

I've read through a couple of the threads on here and followed the steps (knowing that the bootloader screen is blank helps!).

I was trying out the Host/Slave mode and got stuck on the fastboot USB protocol screen.

Right now I am trying the Advent update, but not having any luck.  I have installed the USB drivers, doubled checked that it shows up in Device manager (NVIDIA USB Boot-recovery driver....), then started the Advent "software image_V1.09"exe. This is were I get stumped.

The command windows comes up and run a line, then comes to a complete halt at "Nvflash started".  It doesn't crash as I can close the window fine. It just doesn't do anything!

I've restarted both the pc and the boot loader, sorry to bother but some assistance would be great as I haven't found someone posting this problem!  Once they get here, it appears to be clear sailing for them!

Oh, using Windows 7 Ultimate 64bit with anti virus+fire wall turned off (tried with them on also, no effect)

"C:\Users\John\AppData\Local\Temp>nvflash.exe --bct H5PS1G83EFR-S6C_V24_0625.bct
--setbct --bl bootloader.bin --configfile flash.cfg --odmdata 0x0b0c0075 --create --go
Nvflash started"

It must be something to do with the tablet as I have tried on another laptop and its doing exactly the same thing.

Oh For Flippity Fracking F*** Sake!

Why is it you can repeat the same task 26 times, then on the 27th it does it?!?!

May I ask what is supposed to happen after you have done that. What is supposed to happen on the screen?
Thanks

Absolutely nothing.  If you see anything, even just the backlight, you are not in recovery.  Only way to know if to look at device manager (I'm assuning that you are on Windows) and look for APX (in recovery but wrong drivers - see YAUDIG or AUDI) or Nvidia Harmony Recovery (in recovery, correct drivers).

[beepo666]

I found a few times I thought I'd bricked it (and started to brick it, ) only to realize that I count seconds way too fast, almost twice as fast as 'real' seconds. Now I count 4 seconds while I'm bricking it, appears to go into recovery every time.  

Basically, although it's been said a thousand times on this forum, just keep trying because you can't really brick it glad you got it sorted Simonta.
