I suggest to install the Android ask and use the following fastboot commands.
fastboot oem unlock
fastboot flash recovery recovery.img
*change recovery.img to whatever filename the recovery is and put it in the same directory as your fastboot.
This way you'll learn what a "rootkit" does and be on your way to learning more .

Fastboot mode within bootloader i believe.
If tried reinstalling the drivers and also using the toolkit. I choose not to flash a recovery, just temporary boot so I can install stuff. I tried using fastboot to boot twrp but all I get is a black screen. Seems like sometimes the driver changes. Never had this problem on 4.2

Boot your Nexus to the bootloader by first powering down the phone then simultaneously press and hold the volume down and power buttons for 2 seconds. Once in the bootloader connect the USB cable from the Nexus to your computer. Open a command prompt in the folder where you have installed fastboot, type "fastboot devices", and press enter. If you see a deviceID listed, you will be able to flash TWRP with the command "fastboot flash recovery openrecovery-twrp-2.6.0.0-mako.img" (assuming you are installing TWRP v2.6.0.0); otherwise, you will need to reinstall the Nexus drivers.
^The op wants to boot the recovery, not flash it.
Google removed the "fastboot boot" command in the new 4.3 bootloader. The new way to do this is by using the following command:
Code:
fastboot -c "lge.kcal=0|0|0|x" boot recovery.img

Thank you. Worked fine!!:victory:
Hi, when android 4.3 launched, i went back to 4.2 complete stock with no custom recovery and locked the bootloader to receive the update OTA.
Now I have 4.3 with Z20i bootloader and when i flash cwm, phone gets stuck on the GOOGLE splashscreen and after 1/2 hour moves to the X screen and gets stuck there. Recovery does not works. I had to flash stock recovery and wipe all data to make it work. when trying
Code:
fastboot boot recovery.img (recovery-clockworkmod-6.0.3.6-mako.img)
, it shows a black screen after google and then reboots in safemode whenever any button is pushed.

Normally you have to execute
Code:
fastboot flash recovery recovery.img
Try it with the latest cwm image

flash installs the recovery but nothing works. i have to do a wipe and install the stock recovery to boot it. i wrote it on top
Put your device on the bootloader menu and use this: https://developers.google.com/android/nexus/images#occamjwr66v
Always use the stock bootloader like pretty much everyone who owns the Nexus 4.

It is on the stock bootloader that comes with the nexus 4. The problem is after 4.3 update, i am not able to install cwm on my phone. using fastboot boot command gives black screen while fastboot flash boots a recovery whose none of functions work as it is unable to mount any partition, etc. and i have to install factory image of recovery and do a factory reset to boot the device again to android.

Oh, I thought that was some custom bootloader, apologies.
Em yeah you will have to install the factory image.

Did you try installing an other recovery like either the latest version of CWM or TWRP?

The issue is that fastboot boot recovery doesn't work on 4.3. The new command if fastboot - c lge.kcal=0|0|0|x boot recovery.img

not working. says 0 is a not a command. this is as | works as a batch separator in windows
Update: as i remembered modifier <"> will prevent | from kicking into next line, i tried that, and it works!
fastboot -c "lge.kcal=0|0|0|x" boot recoverycwm.img. but still no action. tried a backup, it starts to backup but files are corrupted. and nothing else work.
This is from efrant guide
Open a command prompt in the directory mentioned above and type: fastboot boot customrecovery.img Note: If you are running the latest bootloader (z20i), the command would be: fastboot -c "lge.kcal=0|0|0|x" boot customrecovery.img Thanks hwti & el_charlie

i loads up but is kind of broken.
any way i can copy the files to my pc to do some analysis. currently the folder which used to save the files has nothing. adb pull /mnt/shell/emulated/clockworkmod/backup/ /android/adbbackupfiles/nexus4 is yielding nothing.
OK. so now i tried using the touch version, and this time there are some files(Still copying). but those are very different than what it was on my older phones and my initial backup. Sorry, I had got away with this due to studies. now the files are .a and.b and the orignal file which is 0KB
Hi, i can't figure out how to boot a custom boot.img with fastboot on last bootloader.
I tried both
Code:
fastboot boot boot.img
and
Code:
fastboot -c "lge.kcal=0|0|0|x" boot boot.img
but it won't boot, stuck on Google logo. I'm on stock 4.3 and I tried to boot also the boot.img I extracted from the factory image, same result. Please note that I was able to boot clockworkmod.img using the 2nd command.
Anyone has a solution?
But if you were able to boot the clockworkmod.img, you could only boot into recovery of course? And that worked?
Which other boot images did you try?

Yes, using fastboot I was able to boot only clockworkmod.img (obviously only boot into recovery), nothing else. Clockworkmod worked perfectly and I was able to flash SuperSU.
First I thought my custom boot.img was broken, so I tried the boot.img that I extracted from official factory image, but no luck.
I can't figure out...

fastboot boot boot.img works for me. Kernel/ramdisk compatible with your ROM?
Sent from my phone. Please forgive typos and brevity.
Problem half-solved. I noticed that the phone is actually booting, but the screen is blank... the strange thing is that if I flash the boot.img the screen works! The problem only happens when I try to boot with fastboot... anyone experienced this strange thing??
Hi I've done stupid thing for myself:
i tried flashing 4.4.2 stock rom. coming from 4.2 (i think) did the usual format data/cache. then rebooted then it loops on google logo. I can go to recovery mode.
So are you rooted? Custom recovery? Looking to flash stock? What bootloader do you have? Ota flash? Fastboot flash?

I still cant get fastboot up. ive used minimal fastboot and/or SDK Package. also changed the path for environmental variables.
So more info will help, usually the more info you give the faster your issues can be fixed
Are you in bootloader mode? I take it your using windows, what version? Has adb or fastboot ever worked before? When you type
fastboot devices
You get nothing? Can you post a screen shot of terminal, of environmental variables? Are all proper drivers installed? Does anything pop up in device manager when tablet is plugged into USB while in fastboot, recovery or os? Are you using factory USB cable?

sorry about that.
im in fastboot mode with power and both volumes pressed. i can also go into recovery mode TWRP v2.5.0.0
also rooted and yes windows 7 64 bit. recovery mode or fastboot mode . it doesnt recognized my nexus.
not sure if i have the right drivers. i cant find any drivers to download for nexus 10
Does anything pop up in device manager when tablet is plugged into USB while in fastboot, recovery or os? - No
and yes im using nexus 10 OEM cable.
i really appreciate the time to help me out with this issue.
Its no problem,
The SDK should have the drivers you need, or you can install the universal drivers made by koush or a number of others as well. Just Google search or a search xda for terms like
Nexus 10 drivers
Universal android drivers
Android naked drivers
You will find many that will work just fine for you
If in cmd you type
fastboot
And you see a list of commands than you know you have it installed
When you type
fastboot devices
And you see your serial number your good, if just a blank line then you need to get tab to communicate, this is most often a driver issue. If you can't find ones that work let me know and I'll link some to you, also you may need to uninstall old drivers and than manually install new ones, windows doesn't always do the best job of picking the correct drivers

finally found the driver that works and now
i get R32D2009DAT
Im assuming thats serial number whats the next step
Google search
Android factory images
Here you will download the correct one, latest manta for the nexus 10
Then extract the contents of the zip
Now if you want to keep custom recovery that's a good idea but if you want KitKat you will need stock or at least update to the newest twrp (as you current one won't flash kk)
So if you want twrp then google search
Twrp recovery manta
And then find the latest image, 2.6.x?
Oh and its a good idea to check md5sum for both the zip from android source and for the recovery image, both will tell you what it should be in download screen and there are many ways to check, just google search
Windows md5
There is both official and none official, I personally use Linux command line and can't recall the name of the program I use for windows off hand
Also note that the following commands will wipe all from tablet, it is good to do this but if there is anything real important back it up first
Now from fastboot, enter these commands
fastboot erase system -w
fastboot erase boot
fastboot erase recovery
Now find the bootloader image you extracted from the android .zip
fastboot flash bootloader nameofbootloader.img
Now if you want stock find the system image
fastboot flash system system.img
fastboot flash userdata userdata.img
fastboot flash cache cache.img
fastboot flash boot boot.img
Now find the twrp recovery image
fastboot flash recovery nameofrecovery.img
Here you can boot to new recovery and install superuser or just boot to pure stock, or if you want one of the many great custom ROMs you can boot to recovery and use adb sideload to flash one
