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:

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.
Hi um I'm pretty new to Android phones, and my Captivate's stuck in a bootloop...
I had CyanogenMod 9 on it, based on ICS 4.0.4, which i still have the .zip for if necessary. But I think I did something stupid... in the recovery (which said something about CWMrecovery) mode, I absent-mindedly formatted the /system directory... derp....
Now basically the phone shows the AT&T logo, then shows some kind of recovery screen, it only flashes up for a short time but I can see in the background both an android, like stock recovery mode, and the logo from ROM manager (or something very similar). There is some text at the bottom but it's very small and only flashes up for a split second so I can't read it... and what's worse, it won't boot into recovery...
I'm not exactly sure how to even do it, but random combinations of the volume & power buttons and home.. screen-area-thing work eventually.. but it's just not working now, as i hold the buttons it either just keeps rebooting before it gets past the AT&T logo or ignoring it completely, showing the recovery screen then rebooting again anyway
Sorry it's kinda long.. I tried to be detailed XD
tl;dr CM9 rom Captivate, formatted /system, stuck in bootloop, recovery mode won't work
Any help would be much appreciated
Edit: Forgot to say, I've searched around already but I haven't found anyone else who's bootloop is caused by formatting /system -.-
re flash the rom. you erased the rom.
dont wipe dont format just flash the rom again. you should be back as if it never happened.
If your in a boot loop you might want to invest in a jig, only $6 on eBay
You also said recovery doesn't work? Have you tried putting it into download mode?

jig will not help bootloop.
you are freaking out because of the bootloop and not holding the button combo for recovery long enough.
take out the battery. and replace
hold both volume buttons
then hold power
keep buttons held for 5 seconds AFTER screen comes on.
if your phone turns on and starts to boot, you have recovery and download.

Tried that, isn't working :\ it just ignores it, shows the recovery screen realy quick then reboots again...
I've had this happen on my captivate...only option is to flash back to a stock ROM and work your way back up to CM9 or whatever you were trying to flash originally. To do this your gonna have to get into download mode. A jiff is your best friend in this situation as suggested by several others. however if the button combo for download mode works for you, that is best. Try unplugging the battery, wait for like 10 seconds and plug back in. Have a PC running, and make sure you have the drivers installed. have the USB cable plugged into your computer, and while holding both the volume buttons down, plug the cable into your phone as well. This should put you into download mode and your good to go.

thanks cmilldrummin (and everyone else)
I got my phone into download mode fine... but i don't think I have the drivers :s (googling still, but can't find them so far)
Also I got it into recovery mode earlier, re-flashed the same custom ROM but when I tried to load it it just kept loading with the blue android on a skateboard until the battery ran out (It was the same one, CM9)
Is the like actual android system openable in download mode? so I could re-write the /system folder? if not I guess I'll just try to re-flash a stock rom then upgrade.. *crosses fingers*
Best way is to flash back to stock and start fresh.

Np Dolei, but yea back to stock is best, gives you a nice clean slate, with no glitches or errors
Sent from my SGH-I897 using XDA
TRusselo is right. The other posts here are taking the sledgehammer approach for a simple fix. If you cannot get into recovery mode - you're doing it wrong, try again. reflash your rom from recovery and all done.

Try doing this, this has worked for me since I can't get into recovery with the traditional button combo method of holding all three buttons at the same time.
Turn the phone off. Hold the power button, vol up, vol down. Once the ATT boot screen comes on, let go of the power button. Keep holding the volume buttons and voila, you're in recovery.
Agree. Definitely go back to stock if possible first.

Hi,
I just (Well about a month or two ago) bought my-self a motorola milestone then i really loved it...
Now just now, i wanted to change the battery icon for fun right... and then i downloaded the framework-res.apk and i replaced it in the system>framework... then I Kept on receiving a message saying launcher pro unresponive... and there was only on option FORCE CLOSE... so i did but it kept on showing up so bassically i couldnt use my phone... so i pulled the battery out and put it back in i then saw the (M) logo and i thought it was going to be fine... but right after 20-30 seconds. there was a light black screen and i waited there for 10 miutes and nothing happened...

the problem is i can't show the phone on my computer because it needs to be turned on... And also, my power button is broken...Do you think there is another way to access my phone's system on my computer? :crying:
Pull the battery, connect the USB-cable, re-insert the battery and hold the x button while doing so.
This should take you to recovery and from there you can enable USB mass storage mode.

Thanks... But its stuck on the bootloop... I think im getting it fixed tomorrow though...
Thanks Anyways...
P.S: Although if you can think a way around the bootloop...
Try to enter recovery - either by holding X on the keyboard while powering on or pressing down on your D-Pad.
Recovery works, even if the Android system is bootlooping because it lives on a seperate partition.
You already did this before flashing the ROM.

I have done that but then, what do I do?
Just follow the instructions again - it's not that hard.
Press Volume Down and Camera to access menu, apply update.zip, then Open Recovery starts, and so on...

Pulled battery and connected USB... WORKED!
Idk why, but a million thanks!

Hi!
My phone is no longer detectable on my PC via USB (Win7 and Linux), with adb or nvflash with vol+ + vol- or vol- + power or anything.
This problem come from the last official stock update, like what, it's crazy. And no access to hidden menu, etc.
Then, after, trying to solve this problem by applying http://forum.xda-developers.com/showthread.php?t=1981359, by using Rom Manager to replace TWRP by CWM recovery (I know, it's very bad idea...), now my phone don't want to boot in recovery mode, I probably corrupt my system.
Now I have a brick, which can boot and display "S/W Upgrade Please wait while upgrading..." with vol down, but no usb IPX mode or adb or anything (to be sure, I try with another android phone, and work perfectly).
In normal boot, I have LG logo, then rom logo (an X in color), and no change, this animation continue but no end.
I had try many usb cable, reinstall lg drivers and nvidia drivers, different pc and os...
Can we restore recovery mode with special scheme, file, on a sdcard only by boot the phone?
I'm very interested in any ideas that can unlock me.
A big thank you to the community!

Yes, this script only call nvflash with predefined parameters.
My phone is not detectable by nvflash or adb, that is why it doesn't work.

I had a weird brick with my 2x too, after flashing a wrong rom and it was not working at all
So I decided to remove the battery and use a spare one I had in my stuff, and the phone turned on, and when i turned it off again I could reuse nvflash to get back to stock
Did you try something like that, or only charrging the phone for a few hours to see if comes back ?

I don't try another battery, but I have charging the phone with the official lg charger during 4 days, and nothing... This why I asked if we can boot or reconfigure with a "magic" sdcard...
Thanks,

Remove battery.
Press and hold volume- key.
Connect USB cable.
Still press volume- key.
Release when you see screen says "S/W" download.
Insert battery back.
If it worked use smartflash to flash a rom. If the screen still black, then you should try it on another pc. There is no way to screw up the nvflash mode with a bad flash or anything. Keep in mind that keys can be unresponsive during the years. It is realy hard to set my phone to nvflash mode since my volumkeys are unresponsive. I have to press them so hard that my phone nearly break in to half.
If it still not works change usb cable. Check the device manager for devices with a ! in a yellow triangle. If you see that you have some kind of driver issues. If all of these fails to revive your phone, then your phone is dead.

unfortunately it doesn't work, try with a new pc and a new cable... no change. My usb slot in my p990 is probably dead. what is infuriating is the rest works well.
Did you use fast charge with any ROM ?
USB fast charge can damage the USB connector
Did you try using the method to check if the device connects to computer with nvflash, since it does not require battery ?
Try checking this and if the USB connection broke you can send your device to a repair shop to replace it, or even search ebay, aliexpress and etc to find spare parts, and if you do so, I recommed get an extra battery (non original batteries are cheap)
good luck

That is probably a myth.
Try to use a very short usb cable and use the ports on the backside of the pc ( not a laptop!), I always had problems with the front usb ports.
SO I really dunno what could possible made this device die
I nevr had big issues with mine like this, but the closest thing that hapenned when the device stopped working, and did not charge, was to put another battery and this helped
is someone selling this the whole USB flex hardware? I wanna buy it. I am from Philippines.
I installed clockwork mod recovery on my phone. Had a ROM to install, however the ROM installer package wasn't working properly. I mistakenly restarted my phone after having formatted my phone to install the ROM. So now the phone has started up to the white HTC screen and will not go any further. I cannot get it to restart into recovery or to simply power down. Do I need to just let the battery die and then restart into recovery or is there a hardware way to get it to restart without tearing the phone apart? Thanks!
Maybe try power plus volume up?

Just holding the power button for 10 seconds or so. It should power off. It is essentially the same thing as pulling the battery (on phone where you can do that).
