I have rooted my LG Pheonix, and now am attempting to enter fastboot to flash CWM. I tried using adb command of
Code:
adb reboot bootloader
but that just rebooted my phone and didn't actually enter the bootloader. I also tried the power on while holding volume down, but that also didn't do the trick.
Anyone know how to do this?

Hey XDA, I'm a 17 year old kid with a huge problem!
I have an LG Optimus one p500 that's stuck in fastboot mode.
After rooting I downloaded ROM manager and went to Backup my rom I have installed. After selecting that the phone rebooted but was stuck in Fastboot mode. It's been stuck for 2 days and I can't figure out how to exit fastboot or just reboot regularly.
Methods tried:
-Battery pull then turn on
-Press and Hold Homekey, Powerkey and Volume down when booting
-Run fastboot on my command prompt and reboot, continue or flash command
<But they all end in fsatboot mode "Fastboot: Processing Commands" still>
I've tried everything and read everyforum, My questions
1)How can I just reboot my phone regularily! so it's not in fastboot mode?
2) Is there a command prompt for fastboot that willl exit fastboot?
I just want my phone to work normally! Please help, much appreciated!
I think I posted this answer to late
this things also happens with me yesterday and for gaining back my phone first I press back button and volume up and while holding this button I press power key phone will boot into emergency mode and then I used used kdz
my phone came back again without any data delete
but my phone again unrooedt and I rooted it again using gingerbreak.apk
kdz is not necessary in this case (and is not recommended, ever)

a buddy of mine bought a nexus s off of craigslist that is constantly force closing when you boot it. it will force close everything then reboot itself. im attempting to unlock the bootloader but adb devices doesnt show the serial number like it does for my nexus s. when i hold down volume up+down and plug in the usb it goes to the unlock bootloader screen but it doesnt give you the option of yes or no. iv posted a picture to show what it looks like. i cant get the phone into download to try to fix it with odin either. any help would be appreciated.
edit: i finally got my pc to recognize it and we now have an unlocked bootloader, but now iv encountered another problem. i downloaded a recovery image and moved it to the tools folder of sdk when i type in the fastboot flash recovery command it responds with error: cannot load recovery.img.
To unlock bootloader, you have to use fastboot, not adb. So the correct command would be fastboot devices
To boot into the bootloader, you have to press volume up + power, not volume up+down and plug in the usb -- that would bring you into the Download Mode instead

i know, i used adb devices to see if my computer would even recognize the phone. i i can get into fastboot mode by pressing volume up and power but cant send a fastboot command to the phone because it doesnt recognize the phone. when i hold down volume up and down to get into download mode it sends me to the screen i showed in the pic. its the unlock bootloader screen except there is no option to click yes to unlock the bootloader. i would love to get into download mode and use odin hence why i pressed vol up and down and plugged in usb, but like i said it sends me to the unlock bootloader screen.

Before you try to unlock the bootloader I would flash the latest stock rom and see if it boots properly.

Try one of these recovery images:
http://forum.xda-developers.com/showthread.php?t=988686
The full command is
fastboot flash recovery recovery.img
(make sure your recovery image file is actually named recovery.img)
If 'fastboot devices' returns your phone's id you can flash a custom recovery. Otherwise get a full _signed_ stock rom and flash from stock recovery.
Did you install all drivers? Deinstall existing and use either pdanet or sdk build in program to get them. You need like 3 different ones.
Try locking unlocking bootloader again.
There's always the chance you got a defective usb connector.

So I got my phone stuck at the Google logo, but since my volume down button is busted due to a fall I can't get into bootloader or recovery using the traditional method of power +vol down. It there any known workaround for this dilemma?
Code:
su
reboot bootloader
...from any terminal emulator with root access.
If you're not rooted, not sure you can even do this via adb from a computer?
Code:
adb shell
reboot bootloader
Thanks for the tips, however, since the phone is stuck at the boot logo the adb command or fastboot don't work unfortunately
You may need to fix the button then. Otherwise you may be out of luck in your situation.
Hello. I can't get my phone rooted in any way.
I want to Root so I can use TWRP app to flash TWRP recovery .img, and after that I can boot into TWRP recovery and flash new ROM. Correct????
What I've tried so far. OppoTools 1.6.5 = One key root gets hard stuck on Oppo logo at start-up and then I have to flash Coloros ROM again from recovery. Also KingRoot says app not installed. On windows version of KingRoot it gets to some percentage and then it Fails.
I have downloaded "unlocked bootloader" Coloros from this forum that was mentioned before ( Dropbox link )
I have also tried two different ColorOs versions.
I have installed 15sec ADB installer.
I plug my phone into PC and run CMD.
I type adb devices into command prompt and it detects my R7 plus.
then I try to command " adb reboot bootloader "
Phone restarts normally and doesnt go to bootloader. Tell me if im stupid, but isn't Bootloader different than Recovery? Because I can get to recovery command "adb reboot recovery"
I tried some weird button combination Vol+ Vol- + Power and phone semibricked for awhile and PC didnt even react USB driver correctly and almost waved the white flag on this case.
I've enabled USB-debuggin and OEM unlock from devices dev-options.
When I to type command "fastboot oem unlock" on command prompt is says Waiting for device. Nothing pops-up on device and nothing happens.
So now Im stuck on situation that my phone doesnt launch into bootloader where presumably "fastboot oem unlock" would work?
If you have flashed the version of Color OS that has bootloader enabled, you should simply need to go into the settings, enable USB debugging and OEM unlocking, then shutdown the phone before holding the power and volume+ buttons and waiting the ADB bootloader screen. After that, just plug it into the computer and follow the guide on flashing twrp with ADB.
Hello everybody,
I have a LG K520EMW with Android 10 Stock ROM,
According to Treble Check I have a system supporting system-as-root and a system partition A/B
So I downloaded a GSI from the phhusson's Treble Experimentations
But here are my problems :
- the phone won't boot at all on Fastboot mode (tried adb reboot bootloader, adb reboot-bootloader, both from sideload mode and normal mode, tried plugging the phone when it's off holding vol + or Vol - keys, and using QuickBoot, obviously didn't help because the phone is not rooted)
- the phone won't boot either on Recovery mode, it displays "No Command", i've tried all possible key combinations with vol +, vol -, power, camera, nothing happens and it stays on "No Command",
- Can't root with any tool, I tried KingRoot, KingoRoot, mtk-su
The only door open for me right now is sideload, I know I can type "adb sideload rom.zip" but the issue is I haven't unlocked bootloader, so I don't know what happens if I do this...
I've found nothing on the web about this phone, so if anyone have some informations or knows any procedure on another phone which would be applicable on this model, it would be great
Well, some news, i've figured out a dirty vay to access Fastboot mode, very very dirty :
I've tried, just to see what it does, adb sideload lineageOS-18.1-etc.img, and like a rabbit getting out of a hat, a recovery menu appeared and I could access Fastboot,
Now, I still have to find out why when I try fastboot oem unlock or fastboot oem device-id ( LG official procedure )
I have enabled OEM unlock in debugging options of course
On the Fastboot screen, Bootloader version is unknown,
When I try fastboot boot twrp.img, it answers "Download is not allowed on locked devices"
So, if anyone has an idea, I'd be very grateful
