Help! LG G2 Stuck on fastboot - G2 Q&A, Help & Troubleshooting

Okay, this is the entire story.
I rooted my LG G2 and planned to flash a cyanogenmod 11 on it. I managed to adb my zip file to my phone. However, when I tried to boot my phone into fastboot mode, and install the zip, it just stuck there. saying something like fastboot udc()... I can still power on the device and get back to the stock rom but that is obviously not what I want. So how can I get to recovery? And by the way, I managed to factory reset the phone earlier, (before it stuck in fastboot, but it just cleared the data and restarted). Does factory reset delete my cm files? Thanks

Why not just go back to stock and start over from there? Put your recovery and ROM on the phone while stock is running and then use a program like Flashify to flash TWRP or CWM. You know how to do the rest from there I'd imagine.

I have tried that... the ADB stopped working and no matter what recovery software i used, it always stuck on the fastboot...

So then you can't get back to the stock ROM? You said in your original post that you could. And if you can do that, you should be able to do the rest without using ADB at all.
Once it's stock and running, put it into MTP mode while plugged into your computer, copy the recovery, ROM, Gapps, etc onto your SD Card partition, then download Flashify from the Play Store and use it to flash your recovery of choice.
Once your recovery is flashed, you should be able to boot it into it when Flashify asks you to reboot. If that doesn't work, you can download Quick Boot from the Play Store to boot into recovery on your stock ROM.

Yes I can get back to the ROM

OK. I think there are some misunderstandings. I tried to factory reset the phone from the settings. the phone went to fastboot and stuck there. I pressed the power button and it launched the LG Optimus UI. but that doesnt solve the problem. I still can't go to recovery mood. it would just stuck there forever until i press and hold the power button again. I know, it is kind of weird

[Q] ClockworkMod Recovery 5.0.0.1 flashed from ROM manager failed. trying again

I just got the new CWM recovery update through Rom Manager today, and it said it was successfully flashed, but the phone only hangs on the HTC logo when goingto recovery. I can still do fastboot and boot to Android tho, so I'm now gonna try to figure out how to get my recovery back before something bad happes xD
anyone have advice or know where I can download a standalone copy of CWM 5.0.0.1 for G2?
Wish me luck I'll keep updating as things progress
okipokey, solved my own issue. Just had to reflash back to an older recovery and try again a couple times before it stuck.
Time to test out the new recovery!
I decided to flash the upgrade as well. The flash went perfectly. However, I couldn't boot into recovery while within Android. I had to power off and boot into the bootloader and then select recovery... Whenever I tried to reboot to recovery via the Android UI, it restarted and hung at the boot splash screen.. It didn't even work if you selected the option from the ROM Manager itself... I rolled back to previous version as well and its working again. It may be a bug... Early adopters nightmare....
Same here just reinstalled the new version and it worked second time round
must be a bug they havn't quite worked out. Next time I'll do a fastboot flash instead for a low build number.
First time I flashed I tried it from a battery pull through HBOOT and it still hung. Reflash to 3.5 and then back to 5.0 fixed it like you guys

try just reflashing version 5 I had the same problem,but rebooted the phone reflashed version 5 from the rom manager and now is all good
I just sent the dev a comment about it on his Google+
maybe he'll have a fix out soon
Nice one, seems a "double flash" fixes it have just tested 3 or 4 times,seems to be working
yessir, seems to me that if it's a bug its really minor. I can see this being a problem if someone accidentally screws up something on their phone right after flashing the recovery, but not very likely and they'd still be able to reflash through fastboot
Seemed to flash the new version ok. But then, when trying to boot into recovery for the first time, the phone hung on the HTC logo boot splash. Pulled battery, and booted into recovery ok after that.
that's interesting that some of you didn't hang after the battery pull while mine did. Maybe it depends which version we're upgrading from?
stuck at htc
hey i also had this problem and i can't get my g2 to boot up at all. It hangs at the htc screen. I don't know how to fix this issue as i was trying to restore a backup from recovery right after the update. i can't get into recovery or anything else...all i get is the htc screen. Any ideas how I can fix this?

Any sign of a changelog?
I have no idea how to get to a changelog...can you tell me how?

found this
-From Mr.Dutta via G+
I've just finished releasing updates to a bunch of devices to ClockworkMod Recovery 5.
Major changes:
Backups now use tar over yaffs for everything except mtd partitions. Backups got way faster.
Backups now preserve the filesystem type at time of backup. Restores will restore the appropriate filesystem type at restore.
Please update to ROM Manager 4.4.0.3 or higher and try out the new recovery!
Troubleshooting:
Flashing issues: If a recovery does not flash properly, enable erase recovery in settings and try flashing it again. Recovery flashing can be finicky at times.
Bugs: Report them to me! You can always revert back to the older recovery too from within ROM Manager!
So far no issues here while playing around.
my issue is i can't get back to android at all now. i went into rom manager to restore a backup and was told there was an update, then it reflashed the recovery. When i tried to restore my backup it froze and i have not been able to get past the htc screen at all.

can you get into the HBOOT?
pull the battery, put it back in, hold the volume down button and then hit the power button. you should come to a white screen with some options
In the case you want to update your recovery using fastboot method, heres what you'll need:
CWM 5.0.0.1 for G2 (Vision)
HTC Sync drivers
ADB fastboot from Android SDK
Make sure your phone is all the way off by pulling the battery. Get into the HBOOT by holding down the volume down button and then hitting the power. use the volume keys to navigate and the power button to select. Choose "FASTBOOT"
Rename the recovery that you downloaded from CWM to "recovery.img" and put it in your ADB and Fastboot folder
plug your phone into your computer and pull up a command line for your adb/tools/ or adb/platform-tools/ folder where you should have ADB and Fastboot.
under the command line type in:
fastboot devices
<list of devices>
If you do not see your device make sure the cable is plugged in and your drivers are installed. if still nothing try a different cable til you get it to be recognized by the computer.
Once it's recognized do:
fastboot flash recovery recovery.img
when its done:
reboot
I flashed through ROM manager. On suggestion, I checked the box for "erase recovery - recovery will be erased prior to flashing". On first reboot to recovery it sticks at HTC screen. Pulling battery and vol. up+power then entering recovery the 2nd time works just fine.
Hope this helps.

did you use fastboot flash recovery recovery.img ?
after that you were not able to get into recovery?
Was the 802 ROM a modified stock ROM?
If it was a stock modified ROM then find an original AT&T boot.img, you can download any ATT ROM and extract the boot.img. From there get back into fastboot and flash boot.img
fastboot flash boot boot.img
once you have boot.img flashed you should be able to boot into Android. Do not go into recovery and wipe or format anything.

Can you get into recovery? Which recovery you have? If you can get into recovery, then flash the PA ROM again so you can get into fastboot, download CM for the 800, extract the boot.img from CM and flash that boot.img
turn the device on holding the power down key and power button, as soon as the bootscreen comes up...release the buttons and re press them immdeatley.
this should put you on the recovery screen, hopefully from there you can restore your phone.
cheers.

from fastboot flash clockwork recovery if you are not using it and then see if you can mount USB storage. Not sure if it is in twrp or not. Did you use the CM boot.img from the D800 CM 10.2? It should have boot. Did you wipe system?

Stuck in Clockworkmod Recovery

Hi, I've tried to install Android 4.1.2 on my LG E610 L5. The rom I chose was 20d + root + cwm. It worked just fine, but I've accidentally let it update itself, not knowing you should do that on rooted devices. Not whenever I turn on the phone it shows me cwm recovery menu. Rebooting doesn't work and I can't get into stock recovery mode. I've tried hard reset, clearing cash and data, flashing another rom, nothing works. Is there anything I can do other than giving it to service and paying for getting it fixed? Cwm version is 6.0.2.8, I can link to specific download link if that made a difference.

I'd try that, but KDZ won't detect my phone. I can't boot up the system and there's no download mode in cwm. Is there any way to flash stock recovery using cwm?
I basically need anything that would make my phone show up and be detected by kdz. May be rom or different recovery.

okay first of all you need to go to google and find the right driver for your phone
next take the battery out of your phone and then plug it in to your computer while holding the volume up buttons
next go to your computers drivers via ( Start->right click on computer and go to properties->then go to hardware then drivers-> look for something called modem and if your phone is under it then disable it)
next open the KDZ updtaer
install that mx thing
then open KDZ updater set it to 3GQCT and EMERGENCY
then select your KDZ updater
launch update
it may say errors but let it finish.
Phone's display shows LG logo. Left for an hour, nothing happened. If I try to do KDZ update, it says "PHONE WAS NOT FOUND! "

How can I get into fastboot mode? None of the "press volume button and power for 30 seconds" methods work. @edit From what I've read, LG L5 doesn't have fastboot. Damn it.
Did you tried to remove the battery and enter emergency mode ?

OK, so that's really interesting. I've connected the phone to the PC, uninstalled drivers and let Windows Update install it's own. Doing so, instead of being stuck on LG logo, I was now in fastboot mode, despite being said LG L5 doesn't have fastboot. Anyways, I've flashed stock recovery.img I've found here: http://forum.xda-developers.com/showpost.php?p=37363473&postcount=1023. Using Vol- and power button I put it in download mode and managed to install clean soft from official LG website with KDZ. I'm not really sure how it worked, but it did.

Ok every one iv posted a simulare problem a month ago, when you use kdz, and it flashes stock, if after the flashing it stays in a boot loop all you need to do is leave the phone on boot with the lg logo for 10 mins.
After that unplug your phone, put the battery back in.
Now all you need to do is a factory reset, press and hold Vol down + menu, press power after the phone vibritas let go of the power button and keep holdind Vol down + menu for 10 seconds.
The phone will factory reset and boot up normaly.
This works on all versions of L3/L5/L7

but when i do so after the kdz update the phone boots automatically in cwm, so i cant let the phone do what it does during the logo display for 10 minutes. I have an l7
I had no idea what I was doing back then, so I haven't tried a simple solution, but you can try flashing a ROM. The fact you boot straight into recovery is a sign of no/corrupt system, so flashing a different one may fix it. Pick one from Original Development and follow the instructions.

Are you getting to the factory hard reset prompt? You have to go through that to get back into the recovery. Then you can just restore from Backup.

--This is copied and paste from another thread--
"You should be able to get to CWM recovery by using the hardware button (power and volume down held down, flash LG logo for a second, and then shuts off--only then you can turn it back on by holding power and volume down together until LG logo pops on, then let go of both buttons quickly, hold down both power and volume down again, and then quickly let go of the volume down button: a white factory reset screen should pop up and then you can push power button alone twice to enter CWM recovery).
If above does not work, you may need to KDZ back to stock using download mode (google LG G2 download mode) and USB cable (the one that comes with the phone as some USB cable won't work as they're charge only cable). You'll have to reroot with IOROOT25 and start over again."
--
I have no idea what fastboot or download mode is but your phone should be soft-bricked? If you can get into recovery or the factory reset screen you should be safe.
I wasn't able to get into the recovery at first but then I kept trying and trying and managed to get in by luck. Lol. I then wiped everything including Dalvik cache in Advanced and rebooted and was relieved to find it booted into Dirty Unicorns. I guess i was lucky.
