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] SOLVED Problem flashing CyanogenMod 9.1.0 Stable

I rooted my MT4GS a few months ago but stuck with the stock ROM. I decided I wanted to try out the CyanogenMod 9.1 ICS ROM. I followed the following steps:
1) Installed ROM Manager.
2) ROM Manager indicated a newer version of ClockworkMod Recovery and I installed it (5.0.2.7).
3) Using ROM Manager, did a full backup of the current ROM. All went well.
4) Using ROM Manager, downloaded and installed CyanogenMod 9.1.0 stable-doubleshot. I specified to wipe the data and cache partitions. The installation seemed to go normally.
When the phone rebooted, it was stuck at the logo screen. Had to remove the battery to turn it off. Tried a couple times, still the same.
Since I had the backup, I decided I would use CWM to restore the old ROM.
When I boot into recovery mode, it shows CWM 5.0.2.7, but whatever option I try to choose from the recovery menu, The screen just goes blank with the CWM logo in the middle and nothing else happens. Hitting the power button returns me to the menu, but no option works, even power down or reboot. It just goes back to the CWM logo again and I have to remove the battery to shut it down.
So, I thought I would try using fastboot to flash the ROM again. When I boot the phone into the boot loader and select fastboot, then plug the phone in via USB, nothing happens. Windows does not see the phone and ADB or fastboot don't see it either. It's not a driver issue, as the computer is still setup from when the computer was rooted and I connect the phone all the time with no problems.
When the phone is off and plugged into USB or the charger, I still get the charging light, though it goes off after about 10 seconds, then comes back on and cycles like that.
Is there anything I can try at this point, or is my phone bricked? It seems like I followed all the steps correctly. Is there an update.zip I can put in the root folder and see if it picks it up?
Any help would be appreciated.

Ok, after rebooting Windows, I was able to get the USB connection to the phone to work in fastboot. It seems I missed the step described in this thread:
http://forum.xda-developers.com/showthread.php?t=1508556
which states with S-ON you must flash the boot.img separately. I did that via fastboot and the phone boots into cyanogenmod now.
However, I still seem to have the issue with clockwordmod recovery. As long as I do the recovery functions from rom manager, everything is fine, but when I manually boot into the recovery menu, I get the same behavior of any choice from the menu just blanks the screen except for the CWM logo and nothing happens. I tried reflashing the recovery image using fastboot, but still no go.

This is solved also. Seems on the MT4GS, the trackball is the selection button. The power button appears to only be a back button.

What a thread! Two nicely phrased problem definitions, two well explained solutions, and all from the same guy. Sorry we weren't able to help directly, but you obviously found the answers you needed elsewhere in the forum. And you updated the title as well to show it was solved. Thanks.

[Q] Recovery Boot Loop Problem

Had a problem. Hope someone with experience can give me a few answers.
Nave new t-mobile Note 3, SM-N900T. Stock 4.4.2 KitKat Touchwiz rooted.
Rooted to enable SDFix to use SD card as I want to use it.
Everything great! No problems.
Thought it would be wise to have a Nanoid backup.
Opened Rom Manager and made One change in prefrences. I set it for external SD card storage. (mistake?)
Went to 'Backup current Rom' in Rom manager, started it and it started to reboot. Shut down and restarted in a 'Recovery' boot loop??
No matter what I did, Tried holding power, up volume and home button, nothing. Boot loop continued. Removed battery, waited, as soon as I re-installed battery it instantly went back into recovery boot loop.
I don't know what I did, I kept removing battery and trying again and again and all of a sudden, it booted up back to KitKat and now everything is working great again. No problem on any standard reboot.
What happened? I have used this same set up on my S3 and never had a problem.
I would like to backup the current setup for any future problems. But now, I'm afraid to even try.
I removed Rom Manager and re-installed. Made sure that the storage location was reset to internal and it should be OK??
What did I do when I got out of the Recovery boot loop??
So, afraid to try again. Don't want the boot loop again.

Hi. What recovery are you using?
If you haven't installed a custom recovery, then that explains your issue. Basically, the app scheduled a custom recovery script which kept failing in the stock recovery. You should normally be able to reboot into the system holding the power button, thus skipping going to recovery. This also resets the recovery script so everything is back to normal.
Nandroid is normally only possible using a custom recovery like TWRP or CWM.
I saw that you might be able to perform a Nandroid without restarting the phone (so without a custom recovery) using this app: https://play.google.com/store/apps/details?id=com.h3r3t1c.onnandbup&hl=en
I have never tried it. Looks promising though.
But please note that you won't be able to restore the backup without a custom recovery.
EDIT: If you do have a custom recovery, why not boot in recovery mode and make the backup from there?
Cheers

Recovery Boot Loop Problem
I have CWM installed. Setup thru Rom Manager as I have done before on other phones.
Tried it again, same thing. Over and over. Constant reboot. Dosen't matter if I hold the power button or try different ways, same thing.
It says: Recovery booting
Recovery is not seandroid enforcing
Set warranty bit:recovery
If I remove battery and wait a couple of minutes, I can install battery and it dosen't start till I hold power button.
So I held volume down, home button and power button and booted into download mode. From there I cancelled and it rebooted normally.
Everything I've read on boot loops always say 'boot into recovery'. I only wish I could. That's the bootloop.
Any idea on what's wrong?
Thank you for your time and trouble.

Have you tried booting directly into recovery?
So just shut off your phone and then open it by holding volume up + home + power. It should boot into recovery. If it doesn't, I recommend installing cwm or TWRP using Odin instead of Rom manager.
Might be a problem with your current recovery.

Yes, I tried. Does the same thing.
I've never used Odin. All the info I've read mentioned downloading USB drivers and using different .tar files. Checking this and that.
Nothing I've ever done.
No experience with it.
Never had a reason before to use it.
Every instruction website I've read all seem to be different.
I'm gonna have to find out, huh? lol
I've got Odin on my computer, and have the CWM 6 zipped file.
Will do some research.
Thanks

No problem.
A few tips with odin:
-If you have Kies installed, you don't need to install other drivers.
-The file you flash with Odin should have tar or tar.md5 extension
-you have to activate USB debugging from developer options.
-boot your phone into download mode
-run Odin as administrator
-connect your phone. you should see the text Added in Odin. If don't see it, you need drivers.
-you should make sure only auto reboot and f. Reset time are checked
-you should put the file in Pda or Ap(if using latest version)
Click start and wait until it finishes. It will restart itself if you checked auto reboot.
That's about it. It's very safe and easy to use.
Watch some videos on YouTube. You will definitely find some.
Cheers

Update: The install of CWM with Odin seemed to be successful. Still have same problem.
I believe the problem must be somewhere else.
Something is stopping the recovery boot. More research ahead.
When I find out more, will post here and give update.

Strange. You could try TWRP instead of CWM. I use TWRP and really like it:
Here is the download link for your device: http://www.techerrata.com/file/twrp2/hltetmo/openrecovery-twrp-2.7.2.0-hltetmo-4.4.img.tar
This is the Odin flashable recovery.
Here is TWRP page: http://teamw.in/project/twrp2/
EDIT: One more thing. Are these the exact steps you are following when booting into recovery?
"To access recovery mode on your Note 3, turn off the device and press Volume Up+Home+Power buttons at the same time for about 4-6 seconds. When the screen lights up and you see the Samsung logo, release the Power button but keep Volume Up+Home keys pressed until you see the recovery menu screen"
Cheers

Yes, if I use the buttons, the download mode comes up saying 'Boot failed'. That's holding the vol. button 'up'. If I hold vol. down, it loads download mode correctly.
If I try to enter recovery thru Rom Manager, Recovery tries to start and the boot loop starts. ??
I may try TWRP. I've heard a lot about it.
Thanks for the links.

Success!! TWRP works!!
Installed with Odin and it started up fine. Backed up system on my Ext. SD card and rebooted back to OS.
Perfect!

If your ever in Winter Haven, Fl area, I'll buy you a steak dinner.
Thank you.

Stuck on PURE XPERIA Z2 LOGO after full wipe and accidental REBOOT SYSTEM

Good day everyone, I'm using the clone version of A240,
I successfully installed "DeGRuS™ DarkSide_Xperia_Ultimate" ROM on this device a couple of days ago,
but decided to try a different ROM, named "PXZ2-FINAL_A116_signed_by_CMahendra_NEW_F" from Myphone Iceberg group,
I already have all the files needed, so I reboot to recovery, did a full wipe, format system, and then i accidentally hit reboot system, I dont know how the heck I did that but it has been done, now the device is stuck on Boot Logo,
I tried holding power button and then eventually it will shutdown,
but the problem is, when I try to access recovery, it only boot's to the same logo, and then screen turns off for a second or two then back to boot logo.,
can anyone help me with my problem?\
Please! Please I desperately need your help people!

Thank you for your response, luckily I'm able to enter recovery mode after hours of trying to hit [volume up + power] and [volume up and down + power].
Volume +/i and power button gives me options recovery and fast boot (if I'm not mistaken), but only redirects me to Recovery after a couple of mins of trying.
I'm already considering using SPFT by that time, haha
Thanks again for the reply,

How to boot into recovery of start tablet?

Hi, i have a start 101 tablet with a Cortex-A9 cpu, a WM8850 chipset and a Mali-400 GPU and i do have root, it has android 4.0.3, im not very good in these things but i wanted to install google apps on this tablet, i already found a site that gives some links to some zip files for every android version, but i don't know how to install them. The site that gave those zip said that you need to boot into the recovery of the device and press install from zip, but the problem is that my recovery doesn't have any menu on it.
So 2 days ago i tried finding a way to boot into the recovery, holding the power button and volume up do not take me to the recovery, they take me to a screen which says "do you want to do system recovery? press power button before 10 seconds to confirm" and if i press the power button the tablet factory resets, if i wait 10 seconds the tablet shuts down, i also tried holding the power and volume down buttons but they just took me to normal android.
Now yesterday i found a way to boot into the recovery by using an adb command or by using an app called "Reboot manager ROOT", but the problem is that when i use abd or this app and reboot to the recovery, an android robot with a red triangle appears without any menu on it, and searching this on the internet i was told to basically press power and volume up / down untill a menu appears but i can't get this menu to show up, and since there is no menu if i hold the power button to reboot im stuck into this boot to recovery loop unless i factory reset which works and takes me back to normal android, so then i was thinking that maybe the recovery in this tablet does not exist but is that possible? im not very experienced with this but i also found out about custom recovery yesterday, so after like 5 hours on the internet i found a cwm recovery for my chipset and i saw a video on youtube that said that if you had a twrp/cwm recovery for the same chipset of your android device you can make a custom recovery for your device, the video i followed is this:
so i made this custom recovery img file now but how can i flash it? or can i just use the recovery that is already into my tablet to install the google apps?
because i searched the internet a bit and it seems that for flashing a recovery you need to go to the bootloader but i can't access this thing for some reason, power + volume down takes me to normal android so then i tried adb reboot bootloader but it also takes me to normal android, then i also tried the same app i used to reboot into recovery (reboot manager root) but pressing the reboot to bootloader buttons also does not work (it asks for root permission, i press allow and then it reboots to normal android) same with the reboot to download mode button, then as a last attemp i downloaded an app called "flashify" which basically allows to flash recovery, zip and etc, so i first tried to flash the recovery but pressing the button choose file made the app freeze, so then i tried the flash zip option to maybe flash google apps without recovey, but after choosing the zip it gets stuck at downloading 92% and the app freezes and it doesn't seem to have installed the google apps, do you know if there is any way to boot into this bootloader to flash this cwm recovery or maybe any way i can get the normal recovery to work?
thanks for the help!
