Can't boot into recovery After using NVFLASH

hi all i have a T-mobile G2X and im trying to root this phone so... i try to flash CWM using NVFLASH and everything goes according to plan but once i try to boot into recovery by pressing both volume up and down buttons nothing happens. Once i flash stock recovery phone boots and everything is back to normal but once i flash either version same thing happens again. I tried searching but couldn't find a solution. So if anyone can help me or point me to the right direction i will appreciate it.

You boot into CWM recovery by holding power + volume down (do not touch volume up). Hold the keys a good 10 seconds and wait for the fancy LG logo. Once you see the fancy LG logo (not plain white) you can let the keys go. You will then boot into CWM. You are just pressing the wrong keys. Don't boot that way into stock recovery as it will do a factory reset on your phone.

I seem to be having the same problem, except that my phone only shows the s/w update screen and wont revert back to the stock recovery when i try. nvflash just leaves my phone on the update screen for hours. it will boot up normal if i pull the battery and put it back in, but it only shows the s/w update screen when i try to boot into recovery. any thoughts?

To boot into Clock Work Mod Recovery, you press and hold the "volume down key" and the "power/sleep" button at the same time.
Hold the buttons all the way through the Lg boot logo. After a short moment, you will see a distinct "purplish" bluish glow to the logo. At that time, release both buttons.
You will boot into Clock Work Mod Recover and ready for flashing

or use the Terminal:
$su
#reboot recovery

This command does not work on the P999. Recovery is not on the standard partition and this command will only reboot the phone. To reboot into recovery (if you have CWM installed on the physical recovery partition and not installed by ROM Manager) you need either Weapon Rom installed, which has this built in or there is an app on the Android Market written specifically for LG 2X/G2X devices that knows where the recovery is installed and can reboot into it. On some G2X (P999) models it says not compatible because of the way LG wrote the build.prop but instead of saying "Ok" which closes the program you simply use the back key to get to the main program screen and it works like a charm.
This app is also preinstalled as a system app on my roms.

Thank You everyone for ur help. Ive figure everything out and im now running MIUI ROM.

[Q] Vol. down + power dosen't enter the bootloader

After I updated my (unrooeted/locked) Nexus S (9023) to 4.0.3 I wanted to try the 4.0.4 upgrade. After the 4.0.3 the recovery mode lost the backlight, so I figured the it was a good time to root.
I tried this one-click script to unlock. It worked and I installed CWMR and flashed the 4.0.4 upgrade. After a reboot the phone had ICS 4.0.4 and got root.
But not all is working. I lost the ability to get into the bootloader by pressing 'vol down.' & 'power'. The phone just starts normally.
The only way I can get into the bootloader, is to "reboot to bootloader" from a command line. If I choose recovery, I get a picture of an android at its back with a red ! (2105.dk/temp/img_1161.jpg). After two minutes it automatically reboots. What has gone wrong? What does it mean? And how can I fix it?
I'm new at this, so i'm out of ideas

try Vol up + power

Ahhh... now i'm feeling a bit stupid
Okay, i'm able to get into the bootloader, but the problem with the recovery still remains. (what does the picture mean? - 2105.dk/temp/img_1161.jpg)
I've tried both CWRM and TWRP. They seems to flash with no errors, but i still can not get them started from the bootloader (fastboot mode?).

Not sure if it's what you are looking for since I can't see the picture you are talking about but I think it's the recovery "security" screen. When you are there press power first and maintain it to press vol up, you should now be into the recovery...
Also remember stock rom has a script that overwrites any custom recovery with stock recovery each time the rom loads.

Yes, pressing [power] + [vol. up] at the recovery "security/error" screen, starts up a recovery.
I also didn't knew that the stock ROM overwrites the recovery. I never seen it mentioned any where else.
Thanks for the hints.

Okay, after learning how the stock OS trying to reinstall stock recovery, I managed to rename /etc/install-recovery.sh to *.bak
Now the stock recovery stays away, and CWM recovery stays on permanent.
Also, the error screen doesn't show up any more. (never found out what it means)

I had the same problem, because I had already taken the 4.0.4 update. The problem I (and I suspect the others) were having is the reboot after Odin installs the CWM. It happens so fast, there's no time to unplug the tablet and do the button dance to boot into recovery. As a result, the normal boot goes through, and runs the install-recovery.sh that Ryan79 mentioned in system/etc, restoring stock recovery.
Here's how I solved it:
1). On Odin, uncheck "Auto Reboot".
2). Install CWM6.
3). When it goes green, unplug the tablet (still in "download" screen).
4). Reboot manually into recovery (hold power + Vol. left, release power, hold vol. left until CWM screen comes up). I did this straight from the "download" screen. The tablet powered off after a few seconds of holding the power button, then came up to the samsung screen, then I released the power button and continued to hold the volume button until CWM6 loaded.
5). I installed the cwm-root-gtab2.zip file.
6). I selected YES when the "Stock Reboot Fix" question appeared.
Rebooted from recovery, Successful root! Looks to me like the "fix" simply renames the install-recovery.sh, removing the ".sh" at the end. I have now rebooted a couple of times normally, and can still access CWM6 through the buttons.

[Q] only LG logo not booting till even CWM Recovery in P500

Hi,
My p500 phone is just showing LG logo on power up and gets blank after few seconds. I tried all combination volume, power, home keys.
It's not even getting detected by PC. Actually its not reaching to boot loader and stuck before that.
To achieve this situation what I did :
1. I wanted to flash new 4.4.2 ver 12 with this thread.
2. I wiped all data, cache , etc.
3. I tried to update CWM Recovery v6.0.4.8 http://forum.xda-developers.com/showthread.php?t=2564767 from v6.0.4.6.
4. During the installation I pulled out battery by mistake.
5. I rebooted the phone and it got stuck to blank screen after on LG logo screen.
Please suggest something.
I know phone doesn't have any data, rom and CWM recovery (corrupted) and not even boot leader.
Also adb is not able to detect as it's not booting till PC can detect a device.
I am sure it's not hard bricked
Please help , how can at least boot so that adb can detect.
Thanks,
Devesh

Solved
That's how it worked :
1. I pressed a magical combination (dont remember ) :
a. Up volume + back key + power key while inserting battery
or
b. Up down+ back key + power key while inserting battery
which game emergency mode. And that was enough for me.
2.Then, I used standard method to flash recovery and image see here
3. I flashed finally cwm v6.0.4.8 with kitkat 4.4.2.
and it worked

Recovery Flash not working

Hello, I bought a OnePlus one (came with CM11 - 4.4.4) and followed the standard steps to root it
1) unlock bootloader - successful, phone got factory reset, checked the status using fastboot
2) Flash custom recovery (TWRP) using fastboot - always "okay" message
3) The phone DOES NOT boot to recovery after this - it gets stuck at the 1+ logo, or remains stuck for a few seconds and goes to normal reboot. -I've tried using fastboot to reboot phone while holding down volume button
Please help! i've look this problem up and haven't found a solution.
I tried 2.7.0.0, and the latest 2.8.5.1, along with 2.8.6.0, along with trying to use the one plus tool kit. Using the toolkit, even flashing the stock recovery, then booting it didn't work.

after you flash recovery in fastboot, do not issue the fastboot reboot command. you need to manually power off the phone by keeping the power button pressed till it powers off

As the other posted mentioned you have to fastboot flash twrp (2.8.6.0) then power off phone and use volume down + power button combo to get to recovery. Its flashing but if you boot to OS it will be overwritten by CM recovery hence booting directly will alleviate that

Boot into os, enable dev options by tapping the build number a bunch of times in settings-about phone section, go back and go into settings-developer options, make sure "update cyanogen recovery" is unchecked. Flash recovery again, and like people have said, power off the phone and use volume down and power buttons together to boot into recovery.

Thanks for the quick replies guys. I have tried all the above s and none of them have worked

Should I try unlocking the bootloader again?

I recommend going to this guide and following it closely: http://forum.xda-developers.com/oneplus-one/general/guides-bacon-timmaaas-how-to-guides-t2839471
