Cant get in to bootloader/recovery

As it says on the title, I have just rooted went fine then I just installed ClockworkMod Recovery for the LG Optimus 2X went to go in to recovery powering on and holding the Vol down button and a scrren comes up saying
S/W UPGRADE
PLEASE WAIT WHILE UPGRADING....
then nothing happens tried it a couple of time with no joy, having to remove battery to restart, and also it wiped my phone back to stock all my apps etc gone wifi setting etc but the root/superuser is still there
Any idea people????

That is the baseband upgrade screen. You should HOLD power and volume down button!
If that doesn't work are you sure CWM is installed correctly?

I had this exact same problem as well. It led me to be very confused for a good half hour lol. Simple answer is we weren't booting into recovery properly.
1. Turn the phone off.
2. Hold the volume down button and do not let go.
3. Hold the power button and do not let go.
4. Wait and wait and wait.
5. Should see a small piece of text saying "Android" come up after about 10 seconds-ish.
6. As soon as you see this text let go of the power and volume down buttons.
7. You should now be in recovery.
Hope this helped
Edit: Also I don't think the .bat file used to install CWM recovery gives any confirmation after it's done.

Yeah well i ran the CWM again a couple of times then tried again and it worked great thanks every 1
I just think im impatient as going into CWM on the desire a little bit quicker
Once again THANKS

Had the same problem at first too.
Desire is not as "slow" as the 2X when booting to recovery.
Got myself a factory reset the first time I tried...

Yup exactly, the O2X seems to take much longer than other phones to boot into recovery. I used to have a HTC Hero and it literally took a press of two buttons and then wait a few seconds. Strange...

[Q] Stuck on Htc Logo and can not power off

Hi Everyone;
I unlocked my phone for flashing custom rom. After unlocking i reebooted it and was normal. Then i flashed cwm via htc one toolkit. It was successfull as well. Then i go to cwm and made factory reset + wipe cache + dalvik cache. Then i go to install zip from sd card but i could not find my rom file. Thought, it was deleted while unlocking device. Then decided to reboot phone again to copy rom file into the phone and reboot.
But, when i rebooted phone from cwm, it stuck on HTC Logo( Quietly Brilliant screen). Waited sometime, but nothing happened. Then i tried to power off it and boot into bootloader or recovery. I press and hold power button but it does not respond anyhow. When i am holding power button ,back and home buttons are blinking but nothing happens. Almost five minutes i waited as holding down power button but phone does not power off anyhow. i tried all methods like vol down + power, vol up + power and both volume keys + power. But really nothing happens, just blinking back and home buttons. That's all.
I can not simply power off device. :crying:
I also tried boot device via fastboot commands but it says "waiting for device" means computer does not recognize device.
Guys, i need an urgent help. Please...

just keep trying to reboot via holding power or power+vol down. if it doesnt reboot after 30 sec or so let go then try again. if that doesnt work you will have to wait for the battery to die. once you get to bootloader use all in one toolkit to erace cache. then boot to recovery and you rom should be there if not boot back to bootloader and sideload rom

First thank you for your quick reply. Unfortunatelly, power+vol down does not work at all. Maybe i tried 50 times.
Anyhow, after battery die. How can i boot into bootloader. I mean, can phone be charged again in this situation? Also, even if i manage to boot into bootloader or recovery how can i put custom rom file into phone. Actually, i did not use sideload or whatever you mentioned before.
I am serouisly confused now and don't know what to do.
Anyhow, as you said, firlst i need wait to battery die i think. Then i will report back whats happen.
Thank you again btw.

yes your not the first person with this problem. hold power+vol down to get into bootloader. press power button in bootloader to get in fast boot mode. use all in one toolkit to erase cache and side load rom. i recommend all in one toolkit because it automates the process. just select the option then follow on screen steps

Good to hear that i am not the first person That means somehow there is a solution i beleive. Still waiting for battery die. even i had 50 percent battery at the begining but still it holds on I never say again htc battery is bad
I exeprienced that stucking on boot logo several times before with my other htc phones but holding power + vol down/up worked always. This is the first time for me that i faced with power button can not power off device.. Well, ,i hope i wish i can handle out this problem. Definetley with your help.
Regards,

I am having the same problem and don't know what to do :crying:
Today I just got my One. Unlocked bootloader, rooted, flashed Android Revolution rom. Everything worked fine for a while... I wanted to reinstall the rom because I wanted to change some options in the installer - I did not wipe because it was the same rom (big mistake I guess!!). After making the installation option changes, when it was done it proceeded to reboot but now I am stuck in a white HTC logo boot loop hell... (with the red text at the bottom that says "this build is for development purposes only" etc). Holy crap I never had a phone that I could not remove the battery. I cannot get this back into recovery or ANYTHING, it just keeps looping... computer recognizes it, no problem with drivers or anything it just doesn't stay connected long enough (because of the constant looping) to be able to use the toolkit.
PLEASE any advice?? Can't even shut it down omg. Do I have a $600 brick here? :crying::crying:

Did you read the other posts in this thread? The way you do a "battery pull" on this phone is to HOLD the PWR + VOL DOWN button for ~15seconds. Your capactivie buttons will blink, too. On my device, it took exactly 15seconds to reboot. There have been some reports of some phones that get so stuck that you just have to wait until the battery dies and charge it back up.
Alternatively, if the computer is recongizing it, try to adb reboot recovery to try and get into the recovery.

hi again. this morning my battery finally out. Then i put my phone to the charger and started it in fastboot mode( that is a good new) Then i left it for 20-30 minutes to charge a little bit for flashing custom rom.Then i went to recovery and started adb sideload. Sideload was succesful and finally came to aroma installer of trickdroid. I chose my installation options and started to flash rom but process was frozen on 10 percent. It was saying unmount system, unmount cahce and both of them has notification as "already unmounted". But installation was not going on. Then again i tried to go back fasboot mode again by press and holding power+vol down but unfortunatelly lights are blinking but nothing happens again. I think i need to wait to battery die again.
Isn't it quite weird? Why power+vol down combination does not work for me anytime? So, do i need to wait for battery die in every frozen? Do you have any ideas or comments ?
Do i need to go back to stock first ?
EDIT : Battery was out again and i tried once more. This time installation (trick droid) was successful but it frozen at the end this time. And unfortunatelly i can not restart (power+vol down) it again again Holy crap, i am really pissed off with this problem.

O..K...Finally, i managed to start my phone and now it works... Especially thank you skinsfanbdh for your support.
But still i don't know how to solve button configuration problem. But anyhow i think i won't need quite sometim to use it I hope someone can find a solution for that later.

Guide me with steps please

Today i fixed it via asus flash tool.with the right steps it can be flash to stock with no problem

What should I do if I can't even get to the boot screen? I tried holding down the power and volume up buttons, but it just restarts and goes back to the same HTC load screen, what do I do????

45 minutes still no boot.

Wiped data cache AND dalvik, flashed to Malladus, installed GApps and LGApps at the same time. Been sitting at the android animation for at least 45 minutes all three times and still wont boot. I'm downloading stock image but was hoping someone had an experience similar and had an easy solution?

And now I offically think my phone is screwed. I cant boot into recovery, every time I try it wont enter and just reboots because I'm holding the power and volume down buttons. So far I don't think I can enter download mode either.

How to get into TWRP with hardware keys on G2
1. Make sure phone is completely powered down.
2. Press and hold the Volume down button and the Power button.
3. When the LG logo is displayed release the Power button only then immediately press and hold the Power button again.
4. Release both buttons when the Factory Hard Reset screen displays.
5. Press the power button three times, like it says. Even though it says it will delete everything, it won't (I can confirm that if you are at least on v2.6.3.2).
6. After a "factory reset processing" appears, you should get the TWRP flash screen, and you are good to go.

Thanks for replying. I've read how to get into the recovery menu many times. Something is wrong with my phone that prevents me from doing it. I'm assuming its hardware related. I was almost ready to give up yesterday when I found out that if I do the key combo while plugging it into USB, it enters the menu normally. At that point I was able to restore my backup and start again.
I think my phone has a fluke, but I've figured out a way around it.
For those who are using Malladus on Verizon, something was wrong with the radios in the set. I had to find a seperate KK baseband file for the VS980 and flash it over top of the ROM to get it to work. I'm not saying its the same results for everyone, but I tried every variant of his directions (just in case) and was unable to get LTE online. It was the seperate BB file later on that fixed it.

Probably Hard Bricked

I have a G973F that I managed to root and get TWRP installed. I attempted to install the BeyondROM but wouldn't make it past the logo screen so I attempted to flash the original firmware for my device using Odin. There were no errors when I flashed the firmware but the system still didn't boot. I tried to do a factory reset from the recovery menu and it seemed like it completed but now my device will only turn on with "Only official released binaries are allowed to be flashed" at the top. It does not attempt to boot the OS and turns off a few seconds after I release the power button. I have held the Bixby+Vol Up buttons to attempt to get into recovery, doesn't work. I have held Bixby+Vol Down buttons and plugged my phone into my computer to try and boot download mode, doesn't work.
I can't do anything at this point. Does anyone have a way I can use to recover from this?

Hi I got plenty of times this msg "Only official released binaries are allowed to be flashed". You don't have to worry about it. Just try to flash Official Stock and it will be fine.

Unfortunately I cannot get to download mode to do that. My phone turns on flashes the notice and then turns off. If I hold the power button it will stay on but Download Mode and Recovery cannot be booted to.

Thats the tricky part but I know its hard. Try to press together Bixby + Power button. As soon as it goes off then suddenly press Bixby + Volume Down button and attach data cable. I got the same issue because you have only few seconds to do it. If you cant do it then try to get some help of your friend or relatives etc. I am damn sure you can do this. You take reponsibility of buttons and tell your friend to attach the cable once it goes off. And sorry for my bad english

Your English is great and it worked as you said. I totally thought I was out the cost of this damn phone. Was that documented somewhere or did you randomly figure that out?

Its even easier - you can keep the cable attached. Had some story ...)

I never thought my English is good. Hehehehehe By the way I figure this out because it happens to me many times I guess. Anyways glad I helped.

Could not do normal boot. Invalid KERNEL LENGTH.

This message I get when I try to power up my Note 9 N960F/DS.
I got it this way: Been running the same ROM for 2 years. Time to upgrade. Upgraded TWRP via the app. After downloading the ROM image to SD card, I tapped an app called Reboot, with the Recovery option. I suspect this app is from some old installation, and ended up on this unit via data restore. Now all I get is this message on a black screen. No logo, nothing. Message flashes once. If I plug into PC, message flashes repeatedly. Cannot boot to recovery using Vol-+Pwr, Vol++Pwr ineffective.
I suspect I bricked the phone, but I seem to remember once breaking out of this 2 years back, I think. Any ideas, clues, anything?

Try this, power off phone. Press volume up and bixby button and while pressing buttons insert data cable, phone should go to downlaod mode. OPen odin and flash stock firmware.

OK, tried it, display showed the same message until I released the buttons, then flashed the message every 4 seconds until disconnected.

OK, got it into download mode, reflashed twrp, now it's in a boot loop. Will continue working this.

It took a few tries, but I not only got everything working, I restored my data backup and upgraded to Android 10. Thanks all!
