rebooting loop help! (upgrading)

Im trying to flash a new ROM but cannot seem to enter recovery mode:
I had revolver 3.6 and wanted to upgrade to the latest, so I held down power and selected recovery, now its in some type of rebooting cycle where it tries to boot up with the "Eee Pad" in the center and the "ASUS/NVidia" at the bottom, this stays on for about 3 secs then it appears to power off and the cycle starts again.
Holding down just the power button seems to do nothing, but if I hold power+volUP for a few seconds it seems to make it power off for good. From this powered down state, pwr or pwr+volUP does nothing. From this powered down state pwr+volDown brings up the boot screen + the small white letters in the upper right saying to hit volUp within 5 secs to enter RCK but if you do this then you get the reboot loop all over. If you let it sit there Itll allow you to either coldboot or eraseuserdata+cold boot. This allows the tablet to boot up normally.
But I just can never seem to boot to recovery. I have revolver parts and the reboot2recovery and the recoveryinstaller.apk all installed. What am I missing?

What about cwm? Sounds like you still on stock recovery.

How did you root? And how did you flash recovery? Were you ever able to get into recovery?
My gut tells me your recovery isn't compatible with your bootloader and/or boot.img.

Thanks for the help. I don't think i loaded cwwm when i originnally rooted. I reded rooting and it put cwm5 on.

[Q] "No command" when booting to recover on 4.2.1

So I've become tired of pressing "Check now" and being lied to about my system being up to date on the system update screen, and decided to sideload 4.2.2 myself.
This requires booting into recovery mode, but doing so just shows an image on Android on its back with a red triangle over its chest, and "No command" underneath it.
adb reboot recovery yields the same result, as does booting into the bootloader and choosing recovery from there.
After leaving it on this screen for a while, the system automatically does a normal boot.
This Nexus 10 has never been rooted or unlocked: the only thing I've ever done to it is to update to 4.2.1, for which I did wait for the OTA update to become available for my device.
So I'm currently stuck. Anyone have any idea what's going on?

The red triangle is stock recovery. Try hitting one of the volume buttons to get you into the next part of stock recovery. Once there you can select to sideload. I haven't played with stock recovery on the N10 recently so don't remember which volume button and if your press it or hold it.
EDIT: It looks like tapping the power button and volume up button at the same time works. Don't hold the buttons, just tap ... tap it in ...
EDIT2: Just realized you may be having some other issue after I saw someone else mention the "no command" piece.

AHA!
Thank you! Knowing that there's a second step to get to the menu helped me to find this:
Press and Hold the Power button and then tap the Volume Up button within a second to display the menu. This can be a bit tricky if you don’t do it right so if your device reboots just try again.

Once you get "no command" then hold power button and about a second after (if not less ) tap the +volume button . again just TAP the +volume button . don't hold the + volume button

I am in the exact same situation.
Launched the update after 4.2.2 Notification, the device restarted, error message then "No command". I restart manually with Power and Vol+.
My Nexus is fully fonctionnal but always in 4.2.1.
For info : My bootloader is unlocked and the devices is rooted.

I had the same problem. In my case, the thing was I had no recovery installed (the Nexus 10 tries to restore stock recovery if you install another one, and sometimes it fails).
I solved it by installing GooManager from the Play Store and using it to install another recovery.

Could you please elaborate further? I have the same problem (rooted and getting the No Command error) and i am absolutely not sure what to use the goomanager for and what difference it would make

I got the same problem, I have to flash the 4.0 factory image back, then got ota 4.2.1 and 4.2.2, that was before I realized that 4.2.2 factory image has been released by google. Now just wait for some tools to root the stock.

FWIW, this a 2 year old topic.
People are talking about Jellybean here.
Please don't bump threads THIS old. Please find someone else to help out. Thanks for understanding.

this info was very helpful for me, i did the adb reboot recovery, then on the no command screen i tapped the volume + like two or three times and got into recovery, thank you so much!

"No command" message while accessing Recovery

Hello guys !!
I recently flashed the factory image of Lollipop on my nexus 4, since then, I'm encountering a problem while trying to access my stock recovery, i have a screen with a resting droid and an exclamation point saying "No command", I tried to press power button + volume key up, and then I access to a "Android System Recovery <3e>", but I don't know what it is ....
Any help to understand what's happening will be welcome !

The Android System recovery is the stock recovery.Its functionality is quite limited compared to custom recoveries, but still lollipop has added new options there. You are able to get into stock recovery from the dead android screen so you should be fine. If you want more options, flash a custom recovery like twrp.

Update to marshmallow failed

I'm stock 5.1.1, unrooted but bootloader unlocked. Tried updating with ota but ran through the stock recovery Android booted and it said update failed. Do i have to relock the bootloader? Again, im NOT rooted.

Also, when I tried booting into recovery manually, after the bootloader unlocked warning screen came up, it went to what was supposed to be there stck recovery but instead was the dead (lying down) Android with this words "No Command" over him. That's all, no other anything. I Powered off and booted back into Android.

BTW, got the phone second hand....

Download 6.0 and flash in fastboot.

You can also use my thread, but remember, there provided files are for EU version of Moto X Style. If you are using another device, steps will remain the same, but you will need files for your device!

The dead Android is stock recovery. Hold the power button then tap the vol + button. That will take you into the recovery menu.
From LenoMoto:
Code:
With the phone powered off, press and hold the Volume Down button and the Power button at the same time until the device turns on.
Press the Volume Down button to highlight "Recovery mode"
Press the Power button to restart into Recovery mode.
You'll see an image of an Android robot with a red exclamation mark.
While holding down the Power button, press the Volume Up button.

[Guide] What to do when TWRP won't boot from fastboot

Here's the fix I found for when "fastboot boot twrp.img" leads to a frozen Google logo screen
1. Go into the bootloader (shut down, then hold volume down and power together)
2. Choose "recovery mode"
3. Wait until you get the broken android that says "no command"
4. Press volume up while holding the power button to show a list of commands
5. Choose factory reset
After going through these steps, TWRP finally loaded! It took me a couple hours to figure this out, hope it helps others with the same issue save time :good:
