Fast boot and recovery - AT&T LG Optimus G

So I'm preparing to do n4 conversion. However, as I'm making sure everything is ready to go I noticed the only way I can get into recovery is through an app called quick boot, is there something special in the boot loader to get to recovery ? I see no selectable options.
When in boot loader, fast boot is in red , but I can not pull up fastboot devices , when I try to do fastboot reboot, it just sits and stays at waiting for device. Under device manager it says android with a yellow exclamation point when in boot loader.
Lgnpst notices my phone both in download mode and when on, but not in boot loader. I just want to make sure I'm completely set before I do this. Please help!

Btw, all adb commands work, fast boot options comes up , but can't do anything in fast boot mode. I'm not that much of a noob, is there anything I can try ?
Its not about what you know , but who you know.

81 views and no responses thought I would at least get some "your a noob" responses

Had the same problem. My drivers weren't installed right turns out. I just ended up using another PC that I knew for sure worked with adb.

I know for sure my adb is working though. In fastboot mode, I look in device manager and under other devices, I get android with a ! When the phone is on, all drivers are working perfectly. I'll try another computer for sure, just baffles me why everything but fast boot works :-/
Its not about what you know , but who you know.

Figured it out with help from kaerey on irc. Had to go into drivers and search manually for the driver.
1: get into boot loader
2. Open device manager
3. Click on android with yellow !
4. Select update driver
5. Search manually
6. Select android devices
7. Select Google under manufacturers
8. Select fast boot
9. Install and enjoy having fast boot again
To access recovery in boot loader:
1. Vol + twice
2. Power button
3. Your in recovery
Thanks again to kaerey from IRC
Its not about what you know , but who you know.

And what divers are you using?
I cant install drivers even in manual search mode.
I cant find fastboot in the list of Google... many zte and adb stuff but no fastboot

Yah....Nothing!!
Try all methods:

I think you may need to use ADB commands to force it to reboot into download.
You may need to do method #4.
You may want to keep adb up and keep typing 'adb devices' to see if it sees the device when you try these different methods. If so - reboot into recovery from that.
You should be able to get into DL mode. Do you have ADB on your computer? If not, get it. Put it on the root of your C:\ and than make sure you get the drivers installed on your PC. Get ODIN and have it open. When that is done, connect your phone to your PC and boot it up. Open a cmd prompt (if you are in windows 7 you may need to open as admin) and navigate to C:\ (or where ever you decided to put ADB). At the command prompt type this exactly minus the parenthesis: "adb reboot download" Should shoot you right into DL mode. At that point you will need to flash a new ROM via ODIN, so make sure you read up.
Hope this works/helps.
I tried all that but cant get into recovery or download mode, my phone is not stuked on vibrant logo it just go to the second logo and then blank screen. Fabrication date is 08-10.

Still trying to fix this I now have no recovery and just get the two icons wipe data and fast boot or it just keeps trying to load a Rom that isn't there so it sticks on the main logo screen if I could get it to show in windows that would be great but now I have no recovery I'm not sure how to even get it to install anything once I do !

As long as you have the fastboot logo, there should be hope. First, you will need to do whatever you can to get your computer to recognize fastboot mode. In order to do this, click on the fastboot icon on your prime and then plug your usb into your pc. What does windows say? Is the device showing in the windows device manager?

It shows up but then says failed to install driver will try it on different pc,s see if it works thanks for the replies seems fairly easy
Ive found on my device that it sometimes requests two different drivers. One for adb/fastboot, and one for mtp. I just cancel the one for mtp as they are not in the naked driver set, and windows then detects another different device.

Okay, you're half way home! The reason why nothing shows in adb is because fastboot and adb are two completely different interfaces. When in fastboot, your device will be expecting the fastboot command only.
Now what you will have to do is find a recovery that is in the blob format. Cwm would probably be okay. Twrp would be good, however the new version requires the nvflash version of the bootloader.
Once you find the blob of the recovery you want, place this in the same folder as the file fastboot.exe
It should be in the same place as adb. If not, place the blob somewhere easy to remember.
Then in a command prompt, type
fastboot -i 0x0b05 flash recovery blobfilename
If you placed the blob in the same place as fastboot, then the above will be the blob filename, or better would be to include the path as well.

[Q] Cyanogenmod installed, but now how do I now install CWM Recovery?

i messed up. i had cwm recovery rom running, but i did not install it. then i installed cyanogenmod. now recovery is cyanogenmod, but i want it to be cwm recovery. im stuck i dont know how to do what i want.
when i boot into recovery, i get cyanogenmod. adb and fastboot commands do not seem to be working. like i cant switch to fastboot via adb reboot bootloader. (no laughing please... is that because i flashed the custom rom???)
google play is not installed yet either because adb and fastboot isnt working like it was before i flashed cyanogenmod. i was going to try to download the cwm rom manager again to help me install (permanently) cwm recovery rom.
im so lost and a noobie, so details for replies please. and thank you for the help.
Its hard to give details in replies without details in your question, please give as much information about your device as possible, especially the make and model
But generally speaking fastboot will only work in bootloader and adb will only work in os and recovery mode
To give more specific answers on what your steps should be please give more device specifics

I don't believe cyanogen has made a recovery since the g1 days so I doubt you have this. But if your not sure what recovery you have upload a pic of it.
If you want a new recovery download the appropriate recovery for your device and use fastboot to install it, see here for help

I BET THATS IT! i installed the custom rom, so debugging needs to be turned back on. the setting was overwritten with the new rom flash. duh! THANK YOU VERY MUCH!
for those of you coming to this thread after me, enable developer mode by going to Settings > About Phone and tapping on Build Number 7
Update: this did solve my problem/question. also watch cyanogenmod's screen. it will ask you to confirm debugging mode use each time or you can say its ok from this pc all the time. the latter worked best for me. another thing i ran into was phone would not power off unless i unplugged the usb cable. if i asked it to power off with the usb cable plugged in, it rebooted instead.

here's how i resolved my complete question:
1) enabled developer mode by going to Settings > About Phone and tapping on Build Number 7
2) activated advanced boot options by going to Settings > Developer Options > Advanced reboot (check it)
3) told phone to always allow debugging mode from my/this pc
4) booted into fastboot mode
5) plugged in usb cable
6) entered the command "adb reboot-bootloader" to switch to fastboot mode
7) entered the command "fastboot devices" to ensure i was in fastboot mode
8) entered the command "mfastboot flash recovery <downloaded.img>" to flash cwm
9) unplugged usb cable
10) reboot into recovery to verify flash was successful

No OS!

Hi,
I got my Nexus 9 around launch date and used Wugs toolkit to unlock bootloader, root and install teamwin recovery.
I kept gettting OTA updates for 5.0.2 but they wouldn't install. After months of ignoring I thought I'd update.
It wouldn't update so I tried to use Wugs toolkit to 'Flash stock + unroot to latest version'.
This failed saying something about no fastboot device, although the device went to the white screen and seemed to be displaying hboot/fastboot as options...
I got frustrated and used TWRP to wipe everything, including the OS!
I'm used to Samsung so expected an Odin type program to flash over my mess... I can't seem to do anything now.
HELP! (Please!)
A reason I don't like tool kits. If they don't work as expected you have no idea what to do next. Follow the long method of this, http://forum.xda-developers.com/showthread.php?p=58956577

Appreciate the reply but I can't enable anything within the device as there is no OS installed...
I have used vol down and power to select fastboot.... Is this "Boot your device into the bootloader" in your guide?
All I get is waiting for device in the cmd window
thanks

Vol down and power does bring you into the bootloader. Do you have usb drivers setup? Go into device manager on your pc with the device connected. Do you have an icon with a yellow exclamation mark? If so right click on it and go to where you can choose a driver from a list on your computer. Choose Android adb composite interface.

Used ODIN to install twrp but phone won't boot into recovery at all

I'm using SM-J510H
So I installed samsung drivers.
I even installed ADB and it's drivers (now i have samsung android in the device manager)
I downloaded TWRP for j53gxx:
https://eu.dl.twrp.me/j53gxx/
The .tar for odin (twrp-3.4.0-0-j53gxx.img.tar)
I did the OEM unlock and debugging thing I even got the notification that the computer was trying to access blah blah I did allow always.
Put the phone in download mode (Down + Home + Power)
Press up to enter download mode.
Connect the phone.
Untick reboot in odin.
Use the ap to select the correct file
Start success!
I try to reload into recovery tried so many different ways even the adb command to reboot into recovery. All I get is a little thing on the top left saying warranty bit recovery and then the screen is black.
It doesn't load into the default recovery it just stays black. I need to take the battery to rest...
I tried with adb but when i force it to load up into download mode (adb reboot bootloader)
adb doesn't recognize the phone anymore
I've now downloaded the android ask maybe that will solve things lol but does anyone have any advice please?
Damn ignore this wrong forum reposted in QandA

First off, i would find your twrp maintainer. I wonder who he is
You have j510h, and you downloaded the j500h twrp. How do you expect me to help you beyond that?
