Try NVFlash or Smart Flash?

Ok, I'll try NVflash but for sure it will take me ages to download this file right now I'm in egypt and wireless sucks here!
Thanks for your help! As soon as I'm done with it I'll tell you!

[Q] Stuck on LG logo after CM7! help!

I recently installed CM7 after rooting my phone with Superoneclick and installing Clockworkmod. However, after installation of CM7, i managed to boot up the system, played around with it and realised that i needed to install the google addon as well. So i rebooted the phone to enter into CWM recovery, however the problem started.
My phone is now stucked on the LG logo screen and would not change. I left the phone in that state till the battery went dead. Recharged the phone and it remained on that screen.
Tried to connect the phone to the PC to flash it with smartflash, but it doesnt work at all. I removed the battery and held the volume down button while plugging in the usb cable. All i see is the phone stucked on the white LG logo screen.
Is there any way that i can reformat the contents of the phone or is my phone certified?
All help would be much appreciated!

Power up directly to cwm by pressing power button and volume down key at the same time.
Once in cwm, full wipe including /system and reflash cm and gapps.
Good luck.

I have tried that method as well. Sorry. Forgot to mention it in my initial post. It didn't work. I have tried to pull the battery, hold down the volume down and power button for at least 20 times now. Each time i get the same screen. The CWM menu does not come up.
Any other ways?

Hmm.....if u can't power to cwm directly then perhaps try smartflash to any stock rom.
1. Download any stock rom
2. Start smartflash app from pc
3. In power off mode, just press volume down to boot to software update screen. Start smartflash stock rom.
4. Boot up stock rom
5. Install rom manager and flash cwm from rom manager. (Or download cwm from Rusty! Cwm thread)
6. Boot to recovery
7. Flash cm rom
8. Flash gapps

Remove battery, hold both vol buttons and plug in USB. Screen should stay blank, but Windows will pick up an APX device. Now NVFlash back to stock and start again.

yup, tried the exact method that you suggested too. But it doesnt work. Still gets stuck at the LG logo.

This method worked! But i have another problem, windows found an APX device, tried to install it but failed. It says driver was not found. Do i have to install a specific driver for this to work? Thanks!

Yes, good point: http://android.modaco.com/topic/335...k-rom-release-v10b-dated-1300166062-15032011/

I have managed to flash the phone and it is back working now. Thank you so much for your help rusty and temasek!

Hi, first post, hope the thread is not too old.
Unfortunately this is my best chance.
I have the same problem on my O1:
Updated from mik's beta 6.5.7 to beta 6.5.8 with the clockwork manager, at the reboot, I was stuck on lg logo.
Unfortunately usb + both volume buttons didn't work.
It remains still at the lg logo.
Pressing home + both volume, it repeately reboots.
In every case I can't go in recovery mode, so I can't wipe the system folder.
Any help will be appreciated,
thank for your time!
PS: sorry, maybe thread in p500, cm7 will be more appropriate.

hold power button + volume down button for 5-10 seconds may work, phone will reboot into recovery mode, then you are able to flash a stock rom or restore your nandroid-backup (if you made one)
good luck, hope it helps you

thanks, I saw a useful post here:
http://forum.xda-developers.com/showthread.php?p=18531050#post18531050
Then I proceded as you wrote.
Now I'm stuck at adroid logo, without the chance to wipe cache.
The recovery does not start: loading bar and then forced reboot...
I don't know what to do

nvflash
maybe you try this link
android.modaco.com/topic/335416-nvflash-setup-instructions-drivers-links-active/
Sorry, i don't get the link working, copy it in your browser, then it should work (i'm posting with my phone that's why the link is'nt correct, but it works with browser, i tried it out)

If the link doesnt work, search 'nvflash lg p990 instructions' with google, you'll see the modaco website with the instructions and the download links

Thank you. A few hours ago, I managed to make it working.
Thanks for your answers, I appreciated.

nvflash is the way to go. Always make sure to use the usb ports on your motherboard (back of your computer) and not some usb hub or so.
Had a black screen for 8 hours, not able to boot, flash, recover or anything.
Changed usb port and I was able to flash the phone again.

you can't have CWM on official v30.There is some workaround , but there is an easy way.Flash v20 patched with CWM and then install CM10.1 or other custom rom

Yes this might fix my troubles too, i kept going back to stock v10 then i used the lg updater for both updates till i was at v30 and then installed cwm. All the times i kept getting that stupid security error..
how stupid :') i also didnt read anywhere about it?? thanks for the reply tho.
I got the job done using a flashed v20 to get into CWM and flashed other rom from there.. Thanks

thank you guys for the help . appreciated
i will go the v20 a try . i hope it works for me

I cannot boot into sw update mode - i removed the batery and connected the usb cable, pressed power+ vol down and nothing happens.
With the battery on, even if I press power + vol down it doesn't enter sw update mode - i get the error message and it then turns off.
SmartFlash doesn't detect the device so I cannot flash another ROM.
Im NOOB at this, so maybe I'm missing something.

[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
