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:

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.

I just exchanged my g tablet at office depot and before I put clockwork recovery on the new one, I decided to update it to see what changes were made to the stock g tablet shell as I have been running vegan for a while. The tablet boots and runs as it should, but I cannot get into recovery mode. I hold power and volume + on boot and it says Dectect recovery key and it looks like it is going to boot into the stock recovery but then it goes to a screen where it looks like the tablet is updating (as if it was installing a new firmware) for about 10 seconds, then reboots into the OS...any ideas as to why I cannot get in?
thanks

I don't think the stock firmware's recovery mode has anything like the Clockworkmod's menu. The stock's recovery mode basically looks for a recovery folder and an update.zip in the internal sdcard's root directory and that is. Since there isn't a recovery folder and a file named update.zip in your internal sdcard's root directory therefore the behavior you observed was correct when you tried to boot into recovery mode. You will have to install the Clockworkmod to give you a more advanced recovery tool on the gtab.
Follow this link by scsione889 to install Clockworkmod on stock rom.

What you are describing sounds very much like a successful update via the standard recovery console.
• Are you sure your update didn't work?
• Did you have the update.zip in the root of your sdcard and the command script in the recovery folder?
• What version do you see in the settings screen?
• Did you know that you may need to wipe user data to see the new UI even with the latest ROM?

thanks for the replies
The strange thing is, I have done all of these things. I just did the same steps I did with the old tablet and cannot get it to work.
I will reread all of the tutorials and follow your steps..maybe I am missing something? I just dont see what I am missing..
Here are my steps.
DL clockworkmod.
Put it in the root of my microSD card.
power on device holding PWR and VOL +.
Wait for the viewsonic splash screen to show detect recovery buttons.
Release buttons.
Then gTablet splash screen appears.
then stock android update screen appears as if it is updating something.
about 10-15 seconds later, device reboots to regular OS..
I have also tried these steps putting the clockwork files on the root of the tablet's storage with no luck...It is crazy that I cannot even get into the stock android recovery. I have never had an issue with this as I have had a Droid, Droid X and Droid Incredible and have already modded on tablet..
The only thing that has changed between my tablet and my returned one is the OS version. This one shows 3389 in the settings and I know I never updated my other one.
Did something change with OS 3389?
Think I rooted it , tried to go into recovery, now I'm stuck. anyone here? right now? maybe can give me live assistance, over IM of some sort? pleaseeeeeeeeee
Looks like you're in the stock recovery, and the clockwork recovery mod was overwritten (it does that every time you reboot).
you can refer to this post for instructions on flashing the cw recovery again and rooting: http://forum.xda-developers.com/showthread.php?t=931865
it's basically just a fastboot command.
What do you mean you think you rooted it

Also someone posted Odin with stock image...perfect for situations like this
http://forum.xda-developers.com/showthread.php?t=947950
i don't think we need to go the Odin way just yet
it sounds like he's in the stock recovery, he just need to do the fastboot, and all that stuff to get things going
The box pouring an arrow onto an android and/or the exclamation mark android is stock recovery. From there, just hit power first, hold it, then hit up arrow, you should get into stock recovery.
If that didn't work, pull the battery and let the phone boot normally. IF you're on 2.3.2 or higher, the install-recovery.sh script will replace the stock recovery in case you some how munged it up.
Reboot into fastboot with the volume key and power key, then when the box with the arrow appears do the power key hold and press the volume up, you should be in stock.
As others said, you can also just fastboot boot or fastboot flash the clockwork recovery image.
You're phone's not bricked, so no panic necessary.
edit: oh, and finally, if you actually succeeded in rooting, you could also just use ROM Mgr app to flash/boot to clockwork recovery, which is what you really should be using.
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)
So, I got my new OnePlus One today and I tried to get CM12 onto it. I was following the [GUIDE] How to Install CM12 on the OnePlus One- Android Lollipop/5.0 on the OPO forums, and everything went well until I tried to get the TWRP on there. I flashed the recovery and rebooted the phone. I turned it off and then tried to boot it into recovery but it doesn't, it just hangs at the OPO logo until I hard-restart it.
I've tried factory resetting it and doing
fastboot oem unlock
but nothing happened. The factory reset pretty much just reset the phone. I think I might've messed up the kernel. How do I fix it?
EDIT 1: I've tried reflashing twrp recoveries and nothing. When I hold power+volume down, it powers on, shows the one plus logo, then reboots and just goes to the lockscreen.
UPDATE 1: I managed to manually flash all the CM12 files and use lollipop. I haven't tried the recovery yet but I'll keep you guys updated (if any of you even care).
UPDATE 2: Apparently flashing CM12 made the recovery work. Everything works as it should and the OTA to the most recent CM12 worked perfectly.
You're probably doing the button combo wrong. Hold volume down, then hold power (so you're holding them together), when you see the boot logo let go of power but keep holding volume down until you reach recovery.

I was curios and enabled advanced reboot to try and boot into recovery and it worked (after I had flashed CM12). Everything's working now.

How did you manually flash CM12? I think I'm having the same trouble you were having. I used the oneplus toolbox from the forum to unlock the bootloader, then flash the TWRP, but no luck in getting into recovery mode. It just boot loops with the oneplus logo until I release the volume down button at which point it then boots to the lock screen.

@Heisenberg I'm also having trouble getting into recovery. I've tried the different button combos (power + vol down; power + vol down and release power) as well as the advance reboot options to get into recovery, but they all fail. I get the 1+ logo and after I let go of the volume down button the screen goes black and boots again to the 1+ screen and then to the lockscreen. It's almost like it doesn't recognize the recovery. I tried putting the stock recovery back on using the image in the OnePlus One toolkit folder, but that one doesn't work either. In addition to unchecking the "CM Recovery Update", are there any other settings that could be causing problems?
For background info, I initially used the toolkit interface to unlock the bootloader and then flash the recovery. The bootloader unlocked with no issue...it wiped my device and I was in sync with the "How to root" video posted by alex.inthi. I got sidetracked after the (seemingly) successful flash of TWRP onto the phone I kept getting booted into the Cyanogen recovery. I realized out that I needed to uncheck the setting to keep it from overwriting TWRP and after that was not able to boot into recovery. After finding your beginners guide (thanks, by the way, very well written) I tried using fastboot from the command line as you show, but still no luck.
Thanks in advance for any help...

Okay, I must have been having a special kind of moment - I've got TWRP 2.8.7.0 running on my handset now. I may have been holding the volume down button too long, or it may be that I was using an older version of TWRP, but I'm going to go with the former. I've also been able to successfully flash and boot into Philz 6.59.2
Having the same problem
I am having the exact same problem and cannot seem to find a solution. Recovery screen just doesn't appear, but goes to lockscreen.
Tried erasing, flashing both twrp, philz etc., but nothing works. The phone doesn't recognize the recovery status. Advanced booting does the same.
Update CM-recovery is checked off, phone is unlocked. I've followed every step of the big guide down to every detail.
Is manually flashing the 12.1 ROM the only way and in that case: is it hard for a relative newcomer?
I have searched around but cannot find a solution. I can't seem to get a working recovery after flashing stock images with and without TWRP 2.8.7.1.
I followed these steps to upgrade to Android 6.0 after verifying the md5 checksum of my download:
adb reboot bootloader
fastboot flash bootloader bootloader-hammerhead....img [it looks the same as before, but I did it anyway]
reboot bootloader
fastboot flash radio radio-hammerhead....img
reboot bootloader
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
....I have also tried with and without flashing cache
fastboot reboot
...then I go back into the bootloader and try to access recovery, but I only get the dead android with the red triangle.
Is anyone else having this problem? Does anyone have a suggestion for a fix?
I'm having the same problem with my Nexus 7 (2013).
Hold down the Power button and press Volume Up.

When I see the dead android? When the phone is off? When the phone is booted into the system?
The dead Android means you have stock recovery installed. When you see the dead Android, hold down the power button and push the volume up then release and you will receive the stock recovery menu

Thanks for the description, but it didn't work. If I hold those buttons long enough, it just loops on the "Google" screen, and if I let go, it boots into the system.
After flashing other times, I have been able to either get the recovery menu or enter TWRP when I choose Recovery from the bootloader menu. Not this time though.
Well, I re-extracted the recovery.img file and flashed it - same problem. I decided to try flashing TWRP again. After flashing I rebooted the bootloader (probably not necessary), then chose Recovery and it booted TWRP like I normally expect.
Still not sure what is happening with the stock recovery. For now I don't have to worry - I'm getting my backup.
Sometimes it doesn't work right away, I keep switching between the volume buttons and it eventually pops up. Only need to tap the volume key, no need to hold it when at the dead Android.
Good luck

Getting into stock recovery from the dead android can be very tricky. As stated above, from the dead android screen, you want to hold the Power Button and press Volume Up quickly, then release. It sounds like you are holding the Power Button way too long which is causing it to do a reboot. I had the same issue the first few times.
Below is a video of someone doing it. On the video, he says to press volume up, volume down, and the power button at the same time until the recovery menu works. But, it is just the power button and volume up. The video will just show you how quickly to press the button combination.

I don't recall having any difficulty in the past, but I think I get it now. Thanks for the tips guys.
