I was using a stocked rooted rom and was planning to planning to change to a custom rom and flashed a wrong kernel.
Currently when I power on my nexus it will show the word google with an unlock icon bottom and proceed to infinite loop of the nexus logo (the colorful X)
I still could go into the bootloader option but then i could not find the fastboot option, there is only restart bootloader, poweroff and a un-clickable recovery mode.
isit possible to flash a new kernel to overwrite the current one? if so, which kernel should I flash? I am not sure whether my nexus is a 4.2 or 4.1.2 version.

The bootloader is fastboot mode. That's where you do all fastboot commands. Flash a new recovery using fastboot and then just flash a new kernel from recovery.

please HELP!!!!!!!!!!!!!!!!!!!! plase
fastboot OEM unlock, fastboot flash a custom recovery, flash the su binaries or a custom ROM, boot, and profit. that's all that is needed(without a toolkit). did you use a toolkit?

try twrp recovery. but cwm should work too. try booting recovery through fastboot..
fastboot boot recovery recoveryname.img
If you have installed the new boot loader latest official CWM will not work unless you flash an unofficial version (6.0.1.5 if I remember well).

The title says it all. In fastboot, selecting recovery shows "Google", then a black screen for a moment, then "Google" again, then the tablet boots normally. I am aware that there's a problem with booting to recovery if you don't hook up a USB cable during Fastboot mode, but I've done that and I still can't get to recovery. I've tried it with stock recovery and after flashing CWM recovery, but no dice on either.
Thanks for any advice you can provide!
Edit: For anyone wondering, this is a 16gb wifi-only Nexus 7 running unrooted 4.2.1.
Have you tried...
adb reboot recovery
or
adb reboot bootloader

I had to down grade to the 3.34 recovery image to get my N7 to boot into recovery and it only does so from an app licate Quick Boot.
do you have the correct bootloader? if not, flash the appropriate version of the bootloader. also try the goomanager app from the market, it installs a (in my opinion at least) better recovery call twrp, or team win recovery project.

The exact same thing happens with reboot recovery - shutdown, Google logo, black screen, Google logo, normal boot. With adb reboot bootloader, I get into fastboot mode, then selecting Recovery does the same thing - Google logo, black screen, Google logo.

This happens with the stock recovery from the Google Nexus 7 Toolkit and with CWM. I believe I did install twrp earlier but the fact remains, I cannot access any recovery under any circumstances, they just progress to a normal boot.
Maybe do a fresh setup(Stock Rom) with nexus 7 toolkit and then try to flash the recovery(again), just an idea.

Did that before posting on this thread, but sadly, no dice.

How do I determine the bootloader version? And why would this cause a problem?

Bootloader 3.41 was problematic (for some) in earlier versions of CWM and TWRP. The correct bootloader version for JOP40D is 4.13. Use this with CWM 6.0.1.9 or TWRP 2.3.2.1
To determine the current version reboot in fastboot mode - power off device, hold vol down + power. Your device should then look like this
I've had parandroid as my ROM, and decided to flash the franco kernel to get some extra battery life. Well, I flashed it, but when it rebooted it got messed up somehow. If I just hold the power button and restart it, it will go to the Google lock screen and then to the Nexus "X" color screen where I let it sit for 10 hours and it didn't change. When it is not plugged into a usb to the computer, I can boot it to the bootloader and go through the options, "Start, Recovery , Power off, Reboot bootloader" but when I select the option, it just goes to the google lock screen. If I plug it into the computer, I can get to the boot loader but I cannot cycle through the options. I'm really hoping I didn't mess it up for good, so any help is greatly appreciated, thanks!
if you an get into your recovery(from your bootloader), just reflash your rom without the franco kernel, and without wiping anything.
I would flash stock using wugs nexus toolkit, probably not the most efficient solution as you will loose root, but the safest IMO. This is what I have done when a custom rom has done this to me( its always been paranoid android for me, even their newest build crashes after boot and kinda sorta soft bricks my n7)

If you can get into bootloader than chances are fastboot should still be working fine, if so extract the original kernel from the ROM you were using (the.zip you downloaded and flashed through recovery originally) open cmd on PC and change directories to the folder its in then from fastboot
fastboot erase boot
fastboot flash boot boot.IMG
fastboot reboot
Should be all good from here

Not really sure what happened, a while ago I had an issue with a game and restored my tablet back to factory settings to fix it, but now I discover that while trying to boot into recovery mode it's not there?
I'm trying to manually install the Android 4.4 Kitkat update, got sick of waiting for the OTA since I haven't gotten it yet and really want to use 4.4, but while trying to go into recovery mode to check everything is working because I'm paranoid like that and while I was successful into booting to the bootloader, trying to go into recovery mode resulted in seeing the little android guy with the red triangle saying no command underneath it, so I'm assuming somehow my recovery is missing?
I then tried to flash stock recovery onto my tablet using the Nexus 7 Toolkit and it told me there was an error in flashing the files and that it was because my device's bootloader was locked.
All I want to do is update to Android 4.4, but how am I supposed to do that when I can't boot into recovery? I've followed all the right steps to do it, did I do something wrong by locking my bootloader and unrooting my device?

Hi, JohnathanKatz...
Unrooting isn't the issue... it's locking the bootloader that's the problem.
If the bootloader of your device is locked, you won't be able to flash anything.
I don't use toolkits myself, but it's pretty straightforward to flash a recovery (stock or custom) using the fastboot tool...
* Unlock the bootloader with fastboot oem unlock
* Fastboot flash the recovery with fastboot flash recovery recovery.img
(...where 'recovery.img' is the name of the recovery image file to be fastboot flashed.)
Maybe there is an option in your toolkit that will unlock the bootloader again... however you do it (toolkit or fastboot), you MUST have an unlocked bootloader before you can flash a recovery.
Rgrds,
Ged.

Hi guys, I actually encountered this problem a minute ago when I attempt to flash a new version of TWRP recovery on my grouper. Whenever I go to the recovery, it just shows 'No command' with a red alert of Android on it (I started to panic when I found that there's an unusual error that prevents me from entering the recovery and this is the first time that I saw this error on my flashaholic experience *btw my previous recovery was CWM) I'm currently on stock 4.4.2 with an unlocked bootloader. I have no idea what problem is causing to display that issue when attempting to enter recovery but then I left it for like 5-10mins while it's displaying that error and after that the device reboots then it just quickly enter TWRP recovery normally as is :silly: sick of that haha, silly ol grouper jesus -_-
EDIT
After entering recovery, I got stuck forever on bootloader and recovery! whenever I reboot, I always get directly enter to the recovery and it forces me to not to enter the ROM oh my god at least I can still configure the recovery so I can backup and flash another ROM :|
ok so i have a razr m i got on ebay. It looks flawless
i unlocked the boot loader and rooted it.
i went into fast boot and pushed cwm 6.0.4.4. I could only get into the boot loader with the key presses "not adb reboot bootloader"
when I go into rom manager i see that i have the latest version of cwm
but I cant boot into recovery
it just shows the boot loader unlocked screen for a while then boots to the regular red eye and regular system
also could not flash cm12 nioghtly from rom manager.
do I just need to rsd the whole thing and start overt?
i retried flashing recovery with mfastboot and it didn't work any better
adb reboot recovery
just the unlocked bootloader screen for a while and then evenutally went into regular boot
ok getting somewhere
i tried a newer version of mfastboot and put the stock recovery back on.
i can now boot to the stock recovery.
i saw that there were issues with the recovery-clockwork-6.0.4.4-xt907.img
what recovery should I be using i am on 4.4.2 183.46.15
i want to get to cm12 eventually
i have tried a number of recoveries. XT901-XT907-TWRP-2.6.3.0-recovery is one
