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.
Hey Everyone,
Im sorry in advance if I'm about to ask the dumbest questions of the day/week, but I'm brand new to this, and I haven't found any answers in any of these threads, so go easy...
Up until now I customized the heck out of my mt4g. Tonight however, I followed HTC's instructions and unlock the boot loader -- as I thought based on what their site said, that I'd be able to flash custom roms to the phone once unlocked.
I was successful in unlocking the Bootloader, but (S=on) still exists. I'm kinda stuck now because I don't know what to do next? Is it possible to go from here to Root, if so, how? I've tried the HTC Super Tool for over an hour and it's not working... not giving me perm S=off. Maybe I'm doing something wrong?
If the phone isn't rooted, then how am I supposed to be able to flash a rom??... Do I do it from the HBOOT menu? Because I can't seem to do that either. If I opt for "recovery" while in HBOOT, I come to a red triangle, and have to do a battery pull.
The stock rom that's loaded now has GB 2.3.4 running.
My goal is simply to get CyanogenMod running on this phone. I just don't know what the next step is. I've already factory reset the phone so all my customizations and apps are gone therefore I don't really care what I have to do to get where I want to go. If it's possible to root from here, what's the next step? If root isn't possible, then how do I flash a new rom, like HTC claims I can do now that the BL is unlocked??
If someone could offer some help, I would be super appreciative!!

Follow that guide and get off the official HTC unlock. You should have read the thread on this forum about it.

okay... I followed the guide and I achieved "perm-root", I believe.
If I go into terminal emulator, and type SU, I get a # returned. I do notice however that when I boot into HBOOT, it still says s=on. Not sure what the difference is between 'perm root' and 's=on' but...
I have rom manager downloaded. I also have titanium backup downloaded and did a full backup.
PROBLEM:
In rom manager, I Flashed ClockworkMod Recovery, and then downloaded the nightly CyanogenMod, no problem, but every time the phone reboots (into recovery mode), I stop at the red triangle?!?!?!
What's going wrong?
Open rom manager and art the top is an option to install recovery-install it, then you should be good to go
I did install recovery. Everytime it reboots into recovery i get the red triangle.
After I get the red triangle, and I hold the Vol Up button and hit power, I come to a BLUE recovery menu (3e) with 4 options:
- Reboot system now
- Apply update from sdcard
- Wipe data/factory reset
- Wipe cache partition
in the middle of the screen, in yellow text it says "E:Can't open /cache/recovery/command"

If you had your device s-off and rooted, why HTC unlock? You just went backwards.
i started with HTC Unlock, then achieved perm-root, but (s=on)
Recovery
Hello,
I had the same issue, I had to flash the recovery with adb
1) If you dont already have it download flash_image and place it in your adb tools folder
2) Download the recovery you need and unzip, then rename to recovery.img and place in the root of your sdcard
3) open terminal and use the following commands
adb push flash_image /system/bin
adb shell
su
cd /system/bin
chmod 777 flash_image*
flash_image recovery /sdcard/recovery.img
4)wait for it to finish
5) type exit
adb reboot recovery
this should solve the issue
You can find the recovery here...including the new touchscreen version
http://clockworkmod.com/rommanager
You can download flash_image here
http://forum.xda-developers.com/showthread.php?t=902493
Thanks to Raichison for all the above
okay #furydude39, im all ready to run through your steps... when i issued the first command "adb push flash_image /system/bin", the handset responded with
"failed to copy 'flash_image' to '/system/bin/flash_image': Read-only file system"
Any idea where to go now? This is obviously why every time i boot into recovery that the processes initiated by RomManager isn't sticking.
an hour later...
I was able to execute the commands correctly that 'furydude39' recommended, and still nothing.
Here's a video I shot of the phone [still] giving me a headache

Someone's gotta have an idea on how to get past this?
Have you turned off fastboot?
Sent from my HTC Glacier using xda premium
yes, just checked... fastboot is off
We need to find out why it is not flashing the cw recovery. Are you able to to mount /system partition and copy files to it? I'm thinking a downgrade might be necessary so you can do gfree and eng bootloader.

okay guys...
I got past the last problem, of getting clockwork mod recovery to work. So, that's all set.
NOW, I use rom manager and i downloaded cyanogenmod 7.1 (stable) + google apps. Once the downloads were complete, I checked all three boxes... backup, clear caches, clear dalvik cache. The phone reboots, goes right into clockwork mod recovery.
the backup goes fine... the cyanogen flash goes without error, and then the google apps flashes without error.
NOW, the phone reboots, and the thing just hangs on the White t-mobile boot screen. Is this supposed to take a while before it goes into Cyanogen's screen? It's been sitting on this white screen for at least 5 minutes.

You should manually wipe and flash. Doing it from the app seems to screw up some of the time. Make sure you wipe system data cache and dalvik before flash. It even helps to reboot recovery after doing wipe before you flash a rom.

In recovery, using the volume rockers, look for factory data reset/wipe. I'm not to positive on the exact names, since I have touch recovery. When you find it select wipe data an wipe cache. after those are wiped, go back then find advance, wipe dalvik cache. When that finished, go back. Select install from sdcard, find your files an install them. Everything should work then.
If I helped, give thanks, if you please.

Thanks all for your suggestions. I finally was able to get Cyanogen to stick. Had to wind up flashing the boot.img manually using fastboot via Windows while in HBOOT screen.
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'm having issues getting recovery to work on a Verizon version xoom. I first flashed CWM version 4.0.0.4. The first time I tried to boot into it, it was stuck on the android with the red triangle for a long time before finally getting into it (coincidentally when I was hitting the volume key, don't know if that's related). Anyway, since then I haven't been able to get into it. It will be suck on the red triangle screen for a minute or two before rebooting into the stock rom (I'm running stock ICS). Since then, I've tried flashing the new TWRP 2.2.2 or whatever version it is and it has no effect. It's still doing the same thing. Any clue what's wrong?
So what I'm reading is suggesting that the android guy I'm seeing is the stock recovery. I'm not sure how that's happening. I'm installing the recovery using fastboot on my PC and being in the bootloader on my xoom. The prompts on both appear to confirm success.
I haven't tried this yet as I'm at work, but I think I've got the issue sorted. The following is what appears to be happening from what I've read.
1. I've still got the custom recovery stalled. When the Android guy pops up, one needs to press volume up to enter the options. Otherwise, it reboots.
2. The recovery flashes are taking because I'm booting back into the rom after a flash. The system's built in recovery protection is re-flashing the original recovery at that point.
3. To make my CWM/TWRP/whatever flash stick, I'll need to power down and then boot directly into the recovery.
I'll post again tonight to say if this works. Hopefully this thread can help out others who have the same issue.

I thought it would be cool to see what the fuss is about rooting and loading a custom ROM but I just dont see the point after playing around the last few days.
I followed the rooting instructions online for the HTC One S ville and then made it to the loading Clockwork Recovery onto the phone and performing an Nandroid backup like it suggested. Well thats where I ran into the issue of not being able to boot into anything else afterwards it would just keep booting to Clockwork Recovery screen. I figured out that I have to hold the power button for 10 seconds and then it will boot properly to stock android ROM. So once I figured that out I began using the tutorial to load the Viper ROM. Once I loaded the viper rom I ran into an issue at step #11
After you configured it, reboot to your bootloader in fastboot mode

I stopped there because I was still stuck at the issue of being booted to the Clockword Recovery screen and unable to get to the bootloader screen. Even now if I shutdown my phone it just restarts to the Clockwork Recovery screen and I have to do the 10 second power button trick to get around it. (remember I did not complete steps 11-20 from post #5 here on the instructions)

Did you wide data/cache before you flashed your custom rom?
There are several ways to get back to your stock rom... If you made a backup of your stock rom via cwm just restore it.. if you didnt make a backup just find the correct ruu for your device and flash it that way, if you dont have super cid you will need to find the correct ruu or it will not flash. If you need any more infomation please let me know and i will do my best to help you out step by step.

Keep trying to get into the bootloader with holding the power for 10 seconds then as soon you see stop flashing hold the Vol- and power then use the all-in-one kit to install TWRP recovery then you wont have this problem any more and you will still need to fastboot boot.img for the rom to work.

No i did not clear the cache or the dalvik cache....im not sure if i wiped data to be honest since it was a few months back. I still have not wiped either caches as of now either.
I'm going to try to download twrp or whatever from the android market right now
