[HELP] STUCK entering nvflash recovery mode

i'm not flash any rom/kernel etc.
i'm only play with power and volume button.
and then my xoom stuck at "entering nvflash recovery mode".
my,question,how exit thaht mode?
i can't adb cause my pc not recognise my xoom.
please,help me to figure out.
thankyou
*PS:-my xoom is m600 [wifi-3g/verizon-usa version]

can you reboot the device? if yes does it stuck on reboot without pressing buttons?
if you cant turn of the device with the power button just press power + vol up at the same time for 3 sec
now it should turn off
this may help you
Here is how I was able to get into different booting modes.
1. Power down
2. Power up and wait for the M sign to show up
3. Press volume down, nvFlash will display, press volume down again, RSD mode will display, press volume down again, fastboot mode will display.
4. Press volume up to select fastboot
5. Go ahead and flash the kernel that you like to restore
can you change the booting mode by pressing vol down?

thanks for your quick response..
yes,i can reboot/powerr off by power+vol UP.
but if only press power button to turn off ,nothing happens.
EDIT:-try this method and no success.

I don't know if I got something wrong up there, but since you didn't flash anything and were just playing around with vol up/down, you should not have to flash anything...
What happens if you just reset your xoom by holding vol up + power for 3 seconds and after that just wait? Imo your xoom should just boot back into android and everything should be fine...

he don´t has to flash something
i am not sure if he wasnt able to turn of the device... and reboot it or something else...
the points for flashing r optional - if he wants to change the kernel or something

Try holding Vol up + PWR for 3 seconds and release, you should see the Motorola logo.
Can you tell us what happened before the xoom went off, or if you have loaded a custom ROM some time ago.

Let the battery go all the way down. Then put it on charge and try to boot-up.
Can you get into fastboot mode? If so, you should be able to reboot into your OS.

Broken CWM

I have flashed the CWM from TF201 by accident. Now the tablet is stuck in that CWM mode. I can't connect to usb using adb mode. Power+volume down does not work anymore. Any way I can reflash the correct CWM?
THanks

If you can boot to OS - you can use fastboot to flash any recovery.. or flash TWRP from goomanager.
upd: sry..don't see about "stuck".

I have made the same mistake. Although I can get the device to fastboot USB mode. I have tried to use CWM with the restore I made before I put in Cyanogenmod 9, as well as putting on the Cyanogenmod experimental #2 for TF300. No error messages at all and it wipes data and cash without any problems.
But I get locked on the Asus boot screen and it does not continue ie I am stuck as well.
I have as well tried to use the TWRP 2.1.5. I get the Teamwin loggo screen, it wipes all the data and verifies all the filesystems and reboots. Still stuck.
Is the device bricked ?
upd:The TF300 can not be shutoff either. When you hold the power button the screen goes black, but after ~5 s the device is starting again and is still stuck on the Asus bootup screen.

if you reboot it holding vol down and power, can you get back into the boot menu, to reselect fastboot?
if holding the power button doesn't switch it off, what happens if you leave it to run out of batteries then do this?
then you can flash the correct recovery.img

Yes, I can get access to the fastboot and I have already tried to flash with the recovery.img. I have as well let the battery run out and tried it once more with the same result.
Still stuck on the asus bootup screen.

power
Hare,
I have same problem.tab cannot power off. Just reboots into cwm.
I was thinking to drain bat. Thanks for sharing that info.

There are a lot of topics about people who broke their devices with TF201's recovery.
Afaik, no one recovered it. Send to Asus.

So the device is bricked then :'(.
Thanks for clearing it up.
Sent from my GT-I9100 using XDA

RMA..
Guillaume,
Thanks for clarification.
I have read that ASUS wants 700USD for replacing/reflashing the bootloader. That was for the tf201. Any way to nvflash it back to factory? I don't believe that they have to change the MB.
I have no warranty left, but I don't want to be gouged by them either.
Any thoughts, info?

Hi,
I've do the same mistake, but I can use adb.
Do youhave any news about our problem?
Thanks
Midyr

unable to power off
My issue is that I have the CWM for the tf201. I did the update from the CWM app in Android. Bad idea. So now the tab does not power off s.t. I can get into the power+vol down mode. Adb does not work since I cannot ( don't know how) to make it go into the usb debugging mode. I have tried several things none of which have worked. Still stuck.
I wanted some feedback for a RMA from ASUS, posted it here but sor far no answers.

Not sure if it would really work, but on my Evo, I don't have to completely power off the phone to do the recovery sequence. I can do it during a normal reboot. There is a point just before the device starts booting again where it is technically "off", and if I hold volume down (don't even have to hold power on my Evo; volume down seems to be the only necessary button) starting at this point, the phone will boot into the bootloader.
So, next time the device reboots, just start holding volume down (possibly power also, just in case) at the "off" point.

[Q] T-Mobile LG G2 stuck in fastboot, can't get into recovery

Update: I messed around with fastboot a bit more and managed to brick it entirely. It's stuck in a boot loop now -- it won't even power off -- and there's nothing I can do about it, so I just took it in to get it replaced.
Hey guys, I know this thread is very similar to others that have been posted, but I've already looked through them and haven't found anything that works for me yet.
My phone was already running rooted stock with TWRP for the recovery. I tried flashing CM10.2 but it was for the wrong model (I downloaded D802 but my phone is of course D801. Oops). Upon reboot, the LG splash screen appeared and then immediately went to a black screen saying
Code:
Fastboot mode started
udc_start()
When I attempt to turn the phone off it just reboots to that screen again. I am still able to use fastboot, and have tried wiping the phone and re-flashing TWRP. It doesn't throw any errors but I still can't actually boot into recovery. I can't use fastboot to flash a new ROM onto the phone though, since it doesn't like .zip archives apparently, and I can't find a .img file of a ROM anywhere.
When I try to use flashtool as described here http://forum.xda-developers.com/showthread.php?t=2541087 it says the device is not connected (probably because it's not in download mode?).
Any help would be much appreciated. All I need to do is get into recovery, it shouldn't be this hard.

That's the same error I got a few days ago when I mis-flashed a new recovery (oops. and be careful when you use 'dd', because a typo can nuke your recovery). I'd get that error message if I tried to boot into recovery, but if I just let the phone boot, it would boot fine. It was easy to fix, but that was because I just used Terminal Emulator to re-flash recovery.
Your best bet might be to go back to stock. Try this thread.

similar issue, but not quite

I'm not in a boot loop, as I can power off and it will stay off. But I am stuck at the Fastboot mode started screen (I can't get download mode to come up). When I do try to get into download mode it flashes for a second, but then goes back to the fastboot mode screen.
I'm hoping to find an image that I can use the fastboot flash recovery command with to re-write my recovery partition.
Any suggestions on where to find this image file? Or am I going down the wrong path?
Thanks,
Joseph

Did you get it to work? I am in the same mode.

I'm stuck here as well. Looking for a fix

Did you guys find a fix? I need help with this...

similar thing here with me
any solution
i cant boot at all, not into download mode, nor recovery,

got this too because i was installing a note3 rom to my d800, acciodentally of coarse. i managed to boot to twrp by doing the power and volume down technique. and from twrp i restored my recent backup

To anyone still stuck in this situation (reboot loop, no recovery etc):
- Unplug the phone from the USB cable
- Hold down the power until the phone turns off
- Wait a couple of minutes with the phone off
- Now hold power and volume down buttons
- When LG logo appears - release power and volume down and hold them again
- When you see a white screen with "reset to default instructions" -- do what it says, meaning pressing the power button a couple of times
THAT should work.

All I did was hold power and volume down until the LG logo came on (not when it flashed for just a split 2nd) and then pressed and held power down again and it came to the white screen. Then I pressed power 3 times and got into recovery

What if I'm stuck on a black screen no matter what buttons I press.

Not sure if you've tried this. To power off fully, press and hold the volume down and power buttons. Do not let go of the buttons. The phone should turn off and the LG logo should appear. Continue holding until after the LG logo disappears. The phone should be fully off and won't turn back on at this point. If you don't see the LG logo, just keep the buttons pressed for about 10-15 seconds and you should be fully powered off by then. You should be able to enter download mode from here (press and hold volume up button while plugging in USB from computer). If you are able to enter download mode, then use the LG mobile support tool in my thread and follow the instructions. This should flash the latest stock system to your phone. If that doesn't work, I have a link to an alternate method for flashing the latest stock system on your phone. Hope this helps.

Bootloop, no Recovery, no Download

Hello,
sorry that I have to bother you with this.
I had a S6 (G920F) with Maniacx Ressurection Remix Unofficial OREO 6.10 , with Magisk 7.10 and TWRP 3.2.1 running.
Because of a problem with calls, I flashed a .zip that fixed the problem before (it's CallAudioFix.zip in that thread – can't find it right now, but I can look for it later if it's any help). That sent my phone into a bootloop.
My problem is that I can't boot into Recovery or Download mode. Windows (in a VirtualBox) finds a SAMSUNG_Android device per USB, but ODIN can't find it (doesn't show anything under ID:COM). ADB in my terminal finds the phone, but it shows it as unauthorized, so I can't use it, either.
I appreciate any help – thanks in advance!

Thanks for your tip, didn't work for me, sadly. If I press and hold the combination for the recovery, I get back into my bootloop. If I press the combination for download mode, nothing happens until I hold it for too long and trigger the battery disconnect (volume down + power).

I'll rather avoid trying to remove the battery for that.
If I hold all buttons, I can only get the "Samsung S6" screen to flash for a second before it goes off and on again (tried for a minute as you suggested).
I tried holding the combos before the kernel screen, directly at it and holding it for a minute, but it only sends me back to the bootloop. Also, I don't get any text on the kernel screen.
Guess I have to keep trying around for a bit...

Try after that flash appears for second to press combo fast i remember that worked for me at same state of bootloop

Samsung Galaxy a40 stuck on "powered by android" screen

Hello, I have a Samsung Galaxy A40 and yesterday I tried to flash LineageOS (I already have experience flashing gsi's), but when i rebooted the system, it just stuck on the "Powered by Android" screen.
It's not even rebooting, it just stays on that screen until the battery dies. So I've tried to let the battery drain and then booting into download mode after charging it a bit by pressing Vol Up + Vol Down and then plugging it into pc, but for some reason it just won't boot into download mode. What can I do now without having to risk booting into that screen and having to wait another full day again?

Hi,
You probably have to flash the latest firmware for your device.
If the phone freeze on the powered by android screen you can press and hold volume down + power and the phone will force reboot.
To reach download mode you can try this :
Turn off the device
Press and hold Volume UP key + Power Key for a while
Release all key when Samsung logo appears then you will see Android System Recovery
Select Reboot to Bootloader
Use Power key to Confirm

The easiest step is the keys but look like it doesnt work for you.
You should try to boot with different key combination get past the bootscreen, otherwise i suggest you to got to a repair center if you can't
