lost root after 4.4.2 upgrade, cant re-root - Nexus 4 Q&A, Help & Troubleshooting

hello guys,
I had 4.4.1 rom+kernel stock, rooted and custom recovery, after the OTA to 4.4.2 lost my root and recovery.
tried re-root with wug's but it gets stuck on "pushing root file to you device".
got superSU application but cant remove it because its system application.
Is there a way to root it?
thanks.

Same here except i had cwm touch latest. It seems i have lost my recovery too. If i try and boot into the recovery menu i get the open hood android with a red triangle.
No custom kernel only custom recovery.

I lost my custom recovery too. But I just reflashed it (adb reboot bootloader, then flashed a downloaded custom recovery via fastboot), and then reflashed SuperSU as well.

I'm having the same problem. Root undone, and recovery went back to stock. Custom recovery doesn't stick after reboot.

I was in the same situation after my OTA of 4.4.2
I had nexus root toolkit, tried to put in twrp with it failed.
Then updated to the latest nrt and then I could flash the latest twrp, havent tried cwm.
and eventually got the root back using nrt

Found the solution to my problem. Used CF Auto Root instead of manually flashing SuperSU again. Cheers guys!

Same thing happened to me. just use fastboot to flash CWM, then before you reboot go into the recovery. then next time you reboot it will still be there. For some reason if I flash the recovery then reboot without entering recovery it will loose the recovery.
Once you have the recovery back, just flash the SuperSU binary through CWM.
Also, IMHO, dont use toolkits... you dont really know whats going on when you use those. Learn to use ADB & fastboot. They are really simple to use and you will be better able to help yourself when you have problems in the future.

Root and recovery without adb?

I tried updating to the new 4.2 ota, I installed stock ROM then booted then back to recovery to install 4.2 update. I lost root as expected, however my ota root keeper says the is not root backup file even though I ran it before doing all that. Not sure what happened.
On top of that I can't reboot into recovery without going through boot loader. It seems as though the update removed my custom recovery too.
I could easily fix all this if I were home, but I am at work today...no adb access. Is there a way to fix root and recovery without a computer?

To enable ADB to go:
Settings-> About Tablet-> Click Build Number for Easter Egg Multiple times! BOOM!
I am not sure if there's a way of rooting without PC and custom recovery.

[Q] Lost root and TWRP after JWR66Y update.

Hi,
I lost root after updating to JWR66Y, and when I open up SuperSU, it says "There is no SU binary installed, and SuperSU cannot install it. This is a problem!"
So I turned off my phone, pressed volume down+power button to go into TWRP and re-flash SuperSU.zip, but the screen only shows broken android with exclamation mark on it.
So, my question is, what do I do? I want to flash TWRP via adb and then flash SuperSU.zip via TWRP. Is that the correct procedure? I'm afraid if something goes wrong I won't have a way to restore my nandroid backup or something.
Thanks.
you always lose root if you take an ota update or flash the factory img. when you flash stock, its just that, stock. its been that way since the beginings of android.
you want to fastboot(not adb) a custom recovery, then flash the latest su binaries via your custom recovery.

[Q] Nexus4 stuck on Google Logo, won't boot into custom recovery

I have a nexus 4, I've previously been able to root it and I've run CM10 and pac roms on there, with no problems. I've also previously flashed CWM recovery, no problems.
However, since I've flashed it back to stock Android 4.3, I now cannot access any form of custom recovery,
When I go into the bootloader and select recovery, the device shows a green android fella lying down, with a red triangle and exclamation mark.
I have tried to use Nexus Root Toolkit v1.7.2 to flash custom recovery, when it says it's booting into recovery temporariily, the phone just shows the google logo and nrt says "Waiting for device".
I've also tried locking and re-unlocking, no change,
Tried flashing permanent and temporary recovery, same problem.
I've tried things on forums but none of them seem to work...
(USB debugging enabled, MTP disabled... adb sees the device, just not when google logo is showing.)
Also, when in android 4.3, SuperSU says "there is no SU binaary installed, and SuperSU cannot install it. This is a problem!"
Any help?
Thanks
I think the best way is to restore it again to stock. If you are using Windows use Wug's Nexus 4 Toolkit. Just don't forget to back up.
Then Root your phone,
Install Flashify
Download TWRP
Install TWRP via Flashify (root required)

I have restored to stock, that's what I'm running.
I'm using that same toolkit.
I've tried re-rooting the phone, but when it tries to boot to TWRP temporarily, it goes back to the google logo and is stuck there, computer doesnt list it as an adb device. I have to holddown power and reboot, but noting has changed.

how to root and still have stock recovery using adb

for rooting i usually uses the wugfresh nexus toolkit and it will root the nexus by using a temporary twrp recovery but how do i do the same using adb?
im using linux now so thats why i used adb to flash 4.4 but i couldnt find a way to flash twrp temporarily(the recovery will only last for one time and returns to stock afterwards) . i could flash twrp and install superuser and then flash the stock recovery but im just trying to figure out how the toolkit does it by using two steps (flashing twrp temporarily and installing super su).

The command should be fastboot -c "lge.kcal=0|0|0|x" boot nameofcustomrecovery.img , with this command you can boot in twrp temporarily
Or simply flash the stock recovery when done.

Try framaroot maybe? There are reports it works on KitKat..

Softbricked phone

I was trying to root my phone and I installed Supersu but than my phone refused to boot. It would open fastboot but nothing after that. I tried to revert to the stock image and i think i made it past that but, that did not fix anything i can still only boot into fastboot. Please help me I want to save my phone.

Flash a temporary rom and then install a stock recovery, and then boot back into stock rom by flashing stock image on pc
through fastboot mode

@fireop958
Installing SuperSU or any root app needs custom kernel installed, if you flash it on stock kernel then its anti-root mechanism will get activated and it will refuse to boot;
now first flash the stock rom via fast boot from here : https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138
then after its booted successfully, then flash the TWRP from fastboot and flash the ElimentalX kernel from TWRP, reboot and check the kernel info in about phone in settings; after then
simply flash SuperSU or magisk from TWRP to get root access
