How to put my vega in nvflash mode?

How to do I put my vega in nvflash mode? I have a custom rom now and I did that before but I forget how. Everywhere where I read I get steps to get into ClockworkRecovery Mod but I need to get into nvflash. I want to instal a new rom but I stuck on this little thing

Hi there
This has been covered before, lots of times. Please use the search function before starting a new thread. It just adds clutter to a great forum.

Take it easy

I read that and I tried that. What I get is that power off screen with, power off, restart, recover options and when I push power button slighty less my screen shuts down but nvflash doesn't apear in device manager, nothing happens

Nothing appears on the screen until you start the rom install. Check its in the right recovery in your device manager on the pc. Nvidia recovery should appear in the usb section. If not reinstall the usb drivers from the advent website.
Good luck.

Rememeber that the vega must be plugged.

I finally did it, thanks a lot! The problem was what you don't need to push buttons for 2 seconds each, just 1 second hold did the trick

Actually it is easy to put your Vega type tablet into nvflash mode without a power cable attached -
1 Press Poer button to start boot.
2 As soon as the screen lights up, press and hold down the POwer button until the boot is aborted and the tablet goes back to being pwered down.
3) Immediately start the Back Button, Power buttin, Back button routine and the tablet will now successfully go into nvflash mode.
Enjoy.

[Q] HELP. Bricked :( Motorola Xoom

Basically its stuck at the M dual core logo screen.
I used android sdk to flash the img file. But now its stuck at the M dual core logo.
Theres a thread with a solution, but it has a filesonic link
Please help.
Also I hate XDA's rules, it makes it hard for me especially during emergencies
I have to wait 5 minutes and I can't post in the developers section.

Are you trying to reboot into the Operating System or reboot into recovery (CWM recovery)?
To reboot device, press volume up plus power--hold it until you see the dual core screen...with luck, it will proceed to boot up the device.
However, if you are trying to reboot into CWM recovery, after rebooting (vol up and power, wait a couple of seconds from when you first see dual core screen and press volume down. You should see starting android recovery in upper left... then press volume up and power to choose it. If you want fastboot, dont wait 2 seconds, just hit volume down, and you should see starting fastboot protocol.

Hey, I know it isn't in English but may help you!

You download you're retail rom in motodev website: http://goo.gl/sQ0Qb
(On the video I download the Brazilian Rom, but download your version!)
Force fastboot mode in you're Xoom holding "volume up" + "power" button and after 3 seconds after reboot press "volume up" to enter in fastboot mode.
;D

Bricked?
I'm pretty sure that the screen lighting up and displaying the company logo is the definition of not bricked. Probably the Volume + Power thing will work, I've had to do that a few times.

Yes thank you m1ch4el.
Now I know there's a way out if I get bricked again, exactly what I was looking for. Now to continue experimenting XD

Which Version is you Xoom and from the sounds of it your xoom is not bricked, if you are able to get into RSD mode on your Xoom you can flash your stock images from MOTO DEVS WEBSITE! Make sure
1. you have newest update and drivers from motorolas website
2. find RSD version 4.2 or later and install it onto your computer
3. find the right file of your stock image hint (its ends with a sbf file)
4. once flash is done restart and BAMO you shouldnt be bricked anymore

[Q] A500 refuses to go into download mode

Ok I have been using the ics leak (version 19) trying to install custom recovery.
All the instructions for going into download mode says to insert paperclip into reset and while holding down reset press power button for exactly 3 seconds then after 1 second release reset button.
My problem is while reset button is pushed in the unit does not respond at all to the power button period. tried it for an hour. Reset button works. power button works. Power button with the reset button pushed in does not work at all.
Is it possible in the ics leak they have disabled the download mode??

Just thought I would update with more information
adb reboot works
adb reboot recovery gives me blank screen. If I hold down power again it will eventually go into recovery mode and tell me recovery is broken (red triangle).
adb reboot download gives me a blank screen like the power is off.
I an thinking my power button may be bad as I have to hold it down for 10 seconds while it is off or in stand by to get it back on or off of stand-by mode.
Anways tried for an hour and a half. Hopefully someone has a clue on this...

I'm confused not sure what you are trying to achieve here. Need more info.
1) which ics leak have you installed?
2) To install a custom recovery using Acer Recovery Installer from the market is easiest. it will backup and restore and allow u to flash roms, does not work for 3.2 tho
3) Download mode is used with the acer upgrade utility (EUU) to rollback to HC 3.2 from ICS or to go back to stock NOT to install a custom recovery.
4) The button press method to enter custom recovery is vol down/power.
So if you can post a bit more info i'm sure we'll get you to where you want to be

I was using the guide here to install the unlocked bootloader then CWM. Sorry I was not more specific.
http://forum.xda-developers.com/showthread.php?t=1516012
Sorry it worked finally it took 2 hours to get into the mode. It seems my power button does not work very well. I had it pressed in for almost 20 seconds for it to take. I noticed that the only way to know before plugging in the usb is to watch for the power button to light up white.
Maybe the guide should be updated to let you know the screen will be blank untill a later part of the process.
At least I was able to get the bootloader unlocked now and CWM recovery install. I may still have to send the unit in if the button stops working.

[Solved-Q] Must be a moron, but I just can't get vol+/power-button to CWM-R to work

This is a painful message to write, but I am desparate. This should be so simple!
Have a U8800 standard (at least it says only "U8800" in settings/about phone.
What have I done:
- Upgraded some time ago to 2.3.5 Rev B522 from Huawei.
- Then rooted it with SuperOneClick.
- Installed ClockWorkMod from Play Store.
- Downloaded CWM Recovery 5.5.0.4 stable from xda and placed the file into the /.cust-backup/image folder via Remount.
- Turned off Fast boot under settings/applications
:: What worked/happened.
- Rooting went fine, ES file explorer and others get root-permissions ok.
- But got into CWMRecovery only via CWM program (Choosing "Reboot into recovery"). Never with the holding buttons vol+ and power-button during power-on.
Figured it was that locked bootloader on B522 that was the problem.
What I did:
- Followed the instructions in http://forum.xda-developers.com/showthread.php?t=1457490 (Get your pink screen back).
- In CWM Recovery flashed "update-B518-bootloader.zip".
- Got "ok installed or something to that effect" from CWM Recovery.
:: What worked/happened.
- Still could not get into CWMRecovery via button-holding. Tried reflashing the B518 bootloader a few times, but just no difference.
Read somewhere that each Huawei firmware-release comes with it's own bootloader, so lets try to install Huawei B518.
- Only place I could find the image was here http://huaweiideosx5.blogspot.no/2012/03/u8800-b518-23-software.html
- U8800V100R001C00B518G001.zip
- Had to take out the external SD-card to get the /sdcard/dload directory on the internal SD-card.
-Seems to be important to have dload on the internal SD-card and not the external.
- Booting the phone with vol+, vol-, power did not start the downgrade, but was able to trigger it via settings/storage/software upgrade.
After downgrade to B518 (Checked version in settings/about phone):
- Deleted /sdcard/dload directory.
- Rooted with SuperOneClick
- Installed ClockWorkMod from play store again.
- Put CWM Recovery 5.5.0.4 into ./cust_backup/image again (think this was unecessary. I think it was already there but did it anyways)
- Turned off Fast boot under settings/applications.
:: What worked/happened.
- The phone is now in B518 software, but still can not get into CWM Recovery via keypressing at boot.
I hold the vol+ and power-buttons all the way to "desktop" so to say, but can not for the life of me get into CWM Recovery that way. Getting into CWM recovery 5.5.0.4 via instructing CWM application to boot into recovery works fine, though.
I am drooling at the thought of ICS Aurora, but I don't dare before I can reliably get into CWM Recovery via keypress.
Sorry if this is very stupid post, but I have tried so much.

Maybe the volume buttons are faulty? Turn off the phone and try this: hold down volume up; while holding press power button as long as the logo comes up. Release power button but continue holding volume up. If it did not work, try doing same with volume down.

Yeah, do what Blefish advised you but do it while the phone is off and charging. I have a kinda broken power key and with this 'trick' it boots faster and more reliable. Keep holding the 3 buttons until you see the recovery.

Thank you both for trying to help me here!
Unfortunately I have had no luck with your suggestions.
Re: Broken keys.
Power and volume-buttons seems to work well when the phone is on. Also when I boot into recovery through the CWM program, navigate to advanced/key-test, the vol+, vol- and power button seems to work well there too.
On pressing the power-button, CWM-R reports Key: 116
On pressing the vol+-button, CWM-R reports Key: 115
On pressing the vol--button, CWM-R reports Key: 114
So I think the keys must be ok, right?
Blefish: I did what you suggested, as I understood it.
When the phone boots, there are three stages of logos.
1. A static logo of Huawei's red "fan?".
2. A short "comet" animation.
3. An animated logo of Huawei's "fan", where some highlight flashes from left to right over the fan.
I hold the power-button in until I see the first static logo, then let go of the power-button and hold the volume-key(s).
Is this the same stage in the boot-process that you were thinking of?
I have tried vol+, vol- and both vol+ and vol-, together with releasing the power-button at that point.
Have not had any success with that, and ended on the "desktop" each time.
AceDroidX: I tried your suggestion as well.
I did this:
1. Shut down the telephone
2. Plugged in the power.
3. A "fan"-logo appears which is replaced by an animated battery.
4. Upon seeing the animated battery, I tried the various key-hold variants.
- vol+ and power : Ended up at desktop.
- vol- and power : Ended up at desktop.
- vol+ and vol- and power : Ended up at desktop.
So not much success either.
I am out of ideas... Can it be that B522 bootloader that still lingers in there, not replaced by installing the B518 software?

Well, idk what else to suggest.. Maybe your problem is here?
Downloaded CWM Recovery 5.5.0.4 stable from xda and placed the file into the /.cust-backup/image folder via Remount.

I remember that when i mount my phone in linux, there was a partition with just the image folder. Some files like boot.img and recovery.img where there. Try to put the recovery image in there and see if it makes any difference.

I'd like see your versioninfo, can you upload a screenshot?
You can check mine from B528

AceDroidX: When I use Remount, I am able to mount that partition as read/write so that I can copy CWM's Recovery image in there. I think it is identical as mounting it up remotely, as you do. I am after all able to boot into CWM-Recovery, just not by key-pressing? I suppose I could boot into Linux and try to mount up the partitions as you do.
Hi kilroystyx: I can not figure out where to find a similar-looking page as the one you have in your picture.
I have the settings/about phone, if that is an older version of what you have there?

You have to dial *#*#2846579#*#*

Off.. I completely forgot about that place!
Here are the right screenshots.
What can you see from this?

Based on the screenshots your installation is fine.
Just one last shoot based on what AceDroidX says, with phone off press Vol+ and hold then connect USB cable to PC or charger and stay holding Vol+ then wait...wait and what you see?

hi all,
i'm using some ics roms and it seems ics supports natively vol++power button to take screenshots but it doesnt work for me... do you know if there are some custom ics rom where it will work?
thank you

Wow.. It is hard to believe.. but I have actually ... eventually found a way to get into that CWM-Recovery every time.
It is a combination of your suggestions.
I have been doing variations, trying to figure something out and eventually there is a method.
What I must do, on this phone, in order to get into CWM-R is this:
1. If the charging cable is in, then unplug first.
2. Turn the phone off.
3. Take out the battery and put it back in.
- This makes a difference on my phone, at least. I am not able to get into CWM-R wihtout taking the battery out first.
4. Press and hold Vol+
5. With Vol+ being pressed continously, insert the charging-cable.
6. Wait for the Fan-animation to finish and the "battery-charging" animation to start.
7. When the battery-charging animation is running and the screen eventually goes black, keep holding the Vol+ button for some time.
- Sometimes it works to keep holding the Vol+ button for only a second or two. Sometimes I must hold it up to 30 seconds.
7. Press and hold the power-button in addition to the Vol+
8. Wait for CWM-Recovery to start.
Thank you very much for your help.
Now I think I can try for ICS!

Try Vol- and Power ON

[Q] which bootloader do i have...

Any easy way to tell?

IF you never update it, I'd say HC (older 1)..If you ever updated to ICS thru OTA update (then you'd have ICS LOCKED Bootloader.
You'd have to manually add ICS UNLOCKED Bootloader to have it.. IF you flashed roms in old days of HC, then u might have UNLOCKED HC Bootloader.
When I load up my tablet that i added it myself, it says Skrilax Cz's bootloader (it is ICS UNLOCKED Bootloader.)
you can run a few programs will tell as well...
Google this... Acer A500 Afterota Lite v1.09 (after running. it will say something like , do you want to save file..it saves info to a .txt file and will say.
maybe this... Acer A500 Manager 1.1 (blackthund3r)

Make sure there is no sd card in the slot.
1. Hold the tablet in landscape.
2. Make sure the switch next to the volume is at the left position.
3. Hold volume up (right side)
4. Push and hold power for 3 seconds while still holding the volume button from step 3
5. After releasing power and still holding volume, a soon as the tablet vibrates, quickly switch the switch next to the volume rocker back and forth.
6. If you did it right, it will show you the bootloader version number
Good luck
