Cant boot into recovery

nextelhalo said:

Hey guys, new to the forum and am looking for some guidance here. I've had my LGOG going great with CM11 and one day I put it on the charger when the battery got down to 1%. The next morning I grabbed my phone and it was off and refused to turn on. I was able to get it on by holding volume up + power and plugging it into a charger or PC but only when it was plugged in. I replaced the battery already to rule that part out. So now i've followed this guide and everything went fine,I flashed Teenybin SBLunlockhttp://xdaforums.com/showthread.php?t=2230106. Only thing is for some reason i cannot boot into recovery mode, fastboot and download mode work fine but when i choose recovery from fastboot the phone shows a google logo and a small lock on the bottom of the screen and then turns off and show's the charging icon. I've been at it for hours and cannot get into recovery to flash a new rom.
My question for yall is am I wasting my time with this? I'm still not convinced that this is not a hardware failure since nothing on the phone works unless plugged into power. Any thoughts would help a ton otherwise i'll have to just cough up the cash for a new one. Thanks in advance guys.

Your battery was probably fine so I would keep it around. That just seems to happen sometimes.
The recovery that teenybins installs is not CM11 compatable. So you need to install a KK recovery, or ADB sideload a Stockish ROM.
For ADB sideload to install a Stockish Rom go here. http://xdaforums.com/showthread.php?p=36270473
To install a recovery through fastboot, DL it from here. http://downloads.codefi.re/shelnutt2/freegee/LG-LS970/ These are for KK
And to install it using fastboot.
fastboot erase recovery
fastboot flash recovery recovery.img

You may need to do a factory reset to get it to boot.

Forgot to tell ya, just pull the recovery image from the zip and use it with fastboot.

Thanks for the reply, this helped me get along with ADB and SDK but i'm still not clear on it. I've got the recovery image needed and ADB running but not sure how to flash the recovery image to the phone. I tried following the guide in the link you provided but it wants you to get into recovery mode on the phone and enable ADB mode but I cant get into my recovery on the phone. Problem. Again though thanks for you help, much appreciated. This learning process brings me back to my days of modding the old Xbox.

So just thinking about your last post, did you recommend installing a stock rom first and then try to install the new recovery image? I am able to put the phone into download mode and i've used LGNPST to push a full stock ZVB rom to it, seemed to work but I didnt know if that was the right way to go and flashed the Teenybin SBL unlock again.

You said you had fastboot. So you can use fastboot to load the kk recovery using those commands. If unsure just google it. Lots of info on fastboot.
As for sideload that was just to get a stock ROM on your SD.
If you lgnpst zvb then your phone should boot up and needs to update to zvc before you do anything else.
But if you flashed teenybins then you should have recovery and be able to flash the kk recovery. Power+ vol up gets recovery. Dn twice on vol button, then power gets you to recovery.
Check the FAQ and root guide. All this info is in there if it's confusing.

Do this then. Grab the zvc bin from the root guide. That is the most current and it has the right modem. Zvb and zv9 have the wrong modem.
Also it sounds like you have stock recovery. Which you will if your using zv? bins.
Then after using zvc bin, use teeny bin. That'll get you to twrp recovery. In twrp flash the kk recovery and you should be good to go.

Will your phone even boot to the stock ROM? If it does, try installing Quickboot from the PlayStore. See if that'll get you into recovery.
I can't remember if it's in the root guide or the FAQ, but I posted another option for a battery issue like yours. Try it and see if it'll do more.
There's some commands that'll wipe through adb. I'll see if I can find them.

There's something we're missing here, so lets start at the beginning
LGNPST ZVC again. This SHOULD get you going.
Now you will have stock recovery. To enter stock recovery, press vol down+power The LG logo will come on, then the capacitive lights. Immediately let go when the capacitive lights turn on. It takes a few seconds to work. And maybe a few tries to get it.
IF that all happens, then in stock recovery, do a Factory reset. IT WILL WIPE YOUR SD/INTERNAL STORAGE!!
Now your phone should boot up to stock ROM.
If that doesn't work, go to ADB and issue these:
adb shell
"dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/cache"
adb shell
"dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/userdata"

These will zero out /cache and /data
Reboot your phone and it should boot up
If not, you may need to LGNPST ZVC one more time and you should be good to go
If no dice again, you might need to try a battery pull, which you should know seeing as how you replaced the battery.

That's about all I got....you could also try getting on the irc and see if someone there has more idea's
Good luck! :fingers-crossed:

Edit: I forgot to tell you that in Stock recovery, use the capacitive menu key to select. The Power button doesn't do it in Stock recovery. Menu is the bottom right of the display and I don't think it's lit, but I'm not sure.
