[Q] LG P500 stuck in fastboot - "waiting for device" - Optimus One, P500, V Q&A, Help & Troubleshooting

Hello.
Earlier today I wanted to try a new JB rom to replace ICS so I transfered it into SD card and tried to reboot into recovery.
Instead of getting to recovery, I got stuck in fastboot mode, so I'm assuming recovery has been damaged.
After a whole afternoon of researching this forum I tried for several times this tutorial in order to install a recovery and afterwards a ROM (http://forum.xda-developers.com/showthread.php?t=1088046) and similar ones in both Mac OS X and Windows 7 (tried both USB 2.0 and USB 3.0 so its not a problem from USB) and I didn't succeed at all.
When I am using Windows 7, when I use "fastboot erase recovery", I keep receiving this message "waiting device". If I write "fastboot devices", I don't get results.
When using Mac OS X, I can get via command line to the folder "platform-tools" where fastboot is located but if I write "fastboot erase recovery" or something, it says "command not found". I've read it could be because I have to set fastboot as an environmental variable, but I having trouble setting it (Mac OS Lion).
Thank you so much for reading. Please help me!!! Any clues would be really appreciated!
-----
UPDATE: I finally managed to communicate with the device.
I used the following commands from this tutorial http://androidforums.com/optimus-m-all-things-root/382525-guide-get-out-fastboot-mode-2.html
fastboot erase boot
fastboot erase recovery
fastboot erase system
fastboot flash recovery
The problem is, now I'm stuck at LG Logo, can't access fastboot... Please help, I think it's even worse now.

boot rom, pull out battery and boot normal, it does or not? if it does use terminal emulator or adb push to install custom recovery, adb will work in fastboot if you had checked android debugging

I don't understand what you mean by boot rom. Every time I turn on the phone, (normal or as POWER+HOME+VOL DOWN) it goes into fastboot. When I pull out the battery, and power again it goes again into fastboot...

[Q] Stuck on Google logo. Unable to push image file to phone... Please help.

Tried various possible solutions and still can't get past the Google logo. Installed adb and Samsung driver but when executing commands such as "abd remount" or "adb push file.zip \sdcard\" in cmd I get an error saying "device not found".
Does anyone know how I could resolve this issue?
I tried clearing the cache and wiping the data from the phone, and even heating the phone with a hair dryer. I'd very much appreciate any help.
looks like you still be able to get in reovery ? if so , then nothing you should worry , just flash a new ROM
Do you mean like a boot image or a recovery image?
If so then you need to put phone in fastboot mode, hold volume up and power til it comes up on screen, then on command prompt on your computer type in fastboot flash recovery xxxxxxx.img (xxxxx is the name of the file like cwm5.0.2.0.img or whatever)
That should give you a working recovery to flash roms from.
Is your boot loader unlocked?
If you wanna mount then just go to mounts and storage and mount USB storage and it will show up on your computer!

Thanks for your reply, seems to be hanging on waiting for device. Fastboot appears to be locked and it just hangs on "waiting for device" when I enter the command fastboot oem unlock... Not sure where to go from here.

Hmmm try going to cmd prompt and typing in adb devices, if you get nothing then your adb isn't set up properly and you need to go into setting and change the path on your computer.
I know the details are sketchy but gimme a min and I will find you a link

Find the Android sdk folder in your computer, move it to the root of C.
I don't think adb is where this guide says it is, there is a read me in the folder where it was saying it has moved to the platform tools folder.
So anyway find the path to the file and put it where the guide says and you should be on the ball.
Forget adb. You need to use fastboot.
Open a command prompt in the directory with fastboot or cd into it.
Put phone in fastboot mode.
On the command prompt type fastboot devices.
You will see your serial number. If you don't recheck and make sure you did everything. Sdk PDA drivers if need be etc.
Fastboot flash recovery custom recovery img name.img
Boot into recovery
Mounts and storage.
Mount SD card
Put a rom for you device on there.
Unmount
Wipe everything but sdcard from recovery.
Flash the rom by going to install zip from SD card......
Okay still stuck trying to connect to my phone. I haven't been able to get my serial number show when typing fastboot devices in cmd. adb is set up and seems to be working but the list of devices is blank when I type in adb devices. The phone was put into fastboot mode both times. I get <waiting for device> when I try
fastboot flash recovery clockwork-5.0.2-crespo.img
I think the bootloader may be locked as it does say LOCKED under lock state, which is probably the reason why I can't get the recovery image to work. I couldn't install PDANet as it wanted to connect to my phone while in debugging mode at the end of the installation. Would it be possible that fastboot oem unlock won't work with without having PDANet installed? I'd really appreciate any further help on this topic.
You need the drivers.

I have the Google USB driver package installed from SDK Manager. I had tried to install some other Samsung driver found on another post but it wouldn't install.
Turns out drivers weren't fully installed, managed to get PDANet installed and could connect to the phone with fastboot devices. Serial number was displayed in cmd. Only problems lies with unlocking the bootloader. fastboot oem unlock fails giving an error: too many links. Anyone have a solution to this?

Did you try booting into bootloader in the first place? Volume up+Power
Then you can use fastboot. Forget PDAnet. Just install SDK and ADB

Yeah I was in bootloader at the time, but I noticed that the Lock-State said locked. So I figured I must first use fastboot oem unlock. If I was to try flash with a stock recovery image would I still need to unlock the bootloader? Like I said I was able to use fastboot devices and get my phones serial number to show up, so I think SDK and ADB is properly installed, path set correctly etc.

I don't think you need to unlock the boot loader to flash a recovery image.
I may be wrong but I remember someone saying that once. I had mine unlocked before I had the chance to try it out. What happens when you type in fastboot oem unlock?

Thanks for your reply, I followed the steps just now and got the exact same error. Before I was trying fastboot oem unlock while in platform-tools but this time I had downloaded the nexussrootICS.zip file, and extracted it to the root of C. I tried fastboot devices and my serial shows up and after fastboot oem unlock I get "status read failed: too many links."
The only difference I seem to have is that in my device manager I have Android Device > ADB Interface, as opposed to SAMSUNG Android Device > ADB Interface.
Not a big difference but that's all I can think of.
the same issue for me. is there any working solution for that?
I recently had success in recovering from this issue.

[Q] Moto G stuck on "Warning Bootloader unlocked" screen

After rootting my moto G around a month ago, the KitKat update has came out, I tried to update on my phone and there was an error, then I tried updating it from the PC, again another error. Then when I would turn my phone on it would turn off after around 1 minute after turning on, So I found a thread to install the update manually, then I had errors flashing partitions as said in the steps on this other website. I uplugged the phone as I kept getting errors, now when I try to turn it on it just gets stuck on "WARNING BOOTLOADER UNLOCKED" screen. Even when I hold down the power button to turn it off, it just turns the screen black, vibrates, turns back on with the warning screen. I cannot enter fastboot with holding down power and the volume key. I am stuck here any tips or anyone know what is going on/ causing the error?
Did u got the phone completlely off? If not - try it and try to Boot in fastboot then.

I am also having same problem. did anyone found solution for this?
There can be many reasons for this: broken ROM, incorrect kernel etc. Unless you know specifically the last thing you changed; you are better off doing a factory reset and installing a new ROM in Recovery or flashing a firmware image via fastboot.
I am having this exact same issue. the phone is stuck on the unlocked bootloader screen. It is still responsive, I can get into the fastboot and even clockwork recovery mod but nothing i do will escapt the bootloop. I even tried a factory reset in Fastboot and Clockwork and the RSD lite method but it didnt work.
Go to the 'Restore Stock Firmware' thread and re-flash your firmware again. I've had bootloops before.

I did, I tried that method but when I get to step 3B I cannot get mboot or whatever to work. First it throws an error and asks for an obscure Adb.dll that i hunted down and put in its folder but then i click it to open and it flashes up for a second then closes. Excuse me while I go cry in a corner for a bit. :crying:

If you have access to TWRP, then are you able to go into the Advanced menu and use the ADB Sideload feature to flash over a ROM from your PC? I had a problem while working with my phone the other day during its initial unlocking and flashing where I'd broken the system install but still had access to TWRP, and by swiping and enabling ADB Sideload, I was able to flash in a new ROM with my phone connected to my computer by running: adb sideload /path/to/rom.zip
Alternatively, you may be able to use the stock firmware restoration procedure detailed elsewhere in this forum to restore your stock firmware via fastboot.
Pardon me if I haven't fully grasped your issue. Hope this helps!

Thanks for the help. I tried ADB Sideload feature in twrp as well the adb sideload /path/to/rom.zip this command/feature was not working from the pc.
Anyways, I tried USB OTG method, copied CM nightly into my flash-drive then attached flash-drive + OTG cable with phone, at first OTG was not working don't know why it could not mount, I restarted phone, went into recovery and then I could installed rom from flashdrive. Finally my phone is working now
I am totally new to android and this rom rooting stuff. Moto G is my first android smartphone coming directly from iPhone 5 so I was scared like hell
If anyone failed with ADB Sideload method please try USB OTG method and your phone will work again. Hope this help others

You first have to select the usb storage in TWRP because TWRP detected internal storage. U can even mount usb otg from TWRP options. after selecting usb then u can see the files in ur usb drive.
I'm stuck on the same Warning screen, it is not a bootloop since the phone just seems to freeze but after a minute I get the windows sound as if you conected something via USB, but the warning screen stays, I've let it for hours and I've flashed stock roms. Even when you flash a no warning boot logo.bin the screen shows again even when mfastboot shows as succesful flash. Out of ideas now, please help

Solution for MotoG locked in bootloader,
I think you must have tried to install another kernel version or so. If you have installed cyanogen try resinsallting the lasted update by going into custom recovery and flashing the latest update in the cmupdater file. Worked for me ! Lets hope that it works for you too. All the best !

[Q] Wiped everything, can't get ADB to see my device anymore

Hi everyone, this is the first time i write here. I've been dealing with this problem for some hours now and it seems i can't get out of it alone.
Today i decided to wipe the N5 and install Lollipop. I downloaded the factory image, wiped everything from TWRP (i know it was unnecessary...), started to flash all the stuff from ADB...but i got some error. I tried again, and got the same error again. So i started to mess around...a guide told me to give adb the following commands:
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
I think it was after this that ADB stopped recognizing my phone, and now i can't even get to the recovery. I tried uninstalling and reinstalling sdk and google usb drivers plenty of times, i even tried some alternative solutions like LGUnitedMobileDriver and Universal Naked Driver.
I can see that windows sees the device (which now only works in fastboot mode) from Device Manager, and that ADB is working (if i give the command "adb version" it responds correctly), but there's no way to make adb recognize the Nexus. If i just install the drivers, Device Manager shows it as "Android Bootloader Interface". A guide i found says to manually select "Android ADB Interface" or "Android Composite ADB Interface", and so i have done (i have to untick the "show compatible hardware" box in the installation process to see this options), but no luck.
Does anybody have any idea how to solve this? What may i have missed?
You need fastboot commands to flash images in recovery. ADB will only recognize the device when you have android running
Try "fastboot devices" command without quotes. It should detect your phone and return a serial number. If so, flash the images (see the sticky on how to return to stock and follow the method 2)
Adb and fastboot are two different things. ASB works in android or recovery but is not used for flashing. Fastboot works in bootloader.
I wrote an "adb and fastboot" thread. Use it uninstall your Google drivers and install naked.
Omg, it was that simple! Thank you guys, you were so fast :good:
If you downloaded the factory image, it seems like you just need to flash that with fastboot.
1). Reboot into the boot loader by holding down volume when powering on.
2). Type fastboot devices to make sure your phone is recognized.
3). Untar the image and execute the flash-all.bat script. This will completely factory reset your phone, including stock recovery. Note this will also delete your internal storage files.
If you don't like this approach, you can also flash the recovery partition with fastboot flash recovery recovery.img, where recovery.img is the TWRP image you downloaded. Once you boot into recovery you can restore a nandroid or whatever from there. Good luck.

[Q] ADB not showing device while in bootloader

Hello guys. I have HTC Sensation, Bootloader unlocked, S-ON, HBOOT-1.27.0000
Yesterday I tried to flash TWRP using fastboot. I have downloaded ADB drivers and also HTC drivers. Connected device and everything was working good. ADB showed my device serial number (or what it is, I don't remember) when I type "adb devices" in command. Then I typed "cd Downloads" to point to download directory (this is where I have twrp.img) and at least "adb reboot bootloader" . Device rebooted into bootloader, but, suddenly, popup appeared on my laptop, it was saying "USB device not recognized". I have closed it and go into command, I typed "adb devices" again, but it didn't show anything at this time. Then I run command "fastboot flash recovery twrp.img" and it returned "Waiting for device...".
After no luck., I have tried to install twrp.img though Flashify. It successfully flashed. I go into recovery, make a backup, perform clean wipe and tried to flash CM12. But it didn't flash. Then I go to restore tab but I can't see my backup. So, TWRP is not flashing anything, I have even tried stock ROM, also it's not backing up things. So now, I'm in bootloop, no OS is installed on my sensation and every time I boot up device, it automatically going into recovery.
I have laptop running Windows 10. I want to make ADB working in bootloader mode or make TWRP working to flash something.
Thanks in advance.

adb doesn't work in bootloader, only fastboot
when you enter in bootlaoder choose fastboot
in the hboot screen you will see fastboot usb
then you can use any fastboot command
i suggest to change the recovery to 4ext
http://d-h.st/rG7
extract the recovery.img and flash it via fastboot command
then before flashing the new rom from 4ext enable smartflash from it(because you are on S-ON)

LG GPAD 7 stuck on Fast Boot

Purchased an Lg Gpad 7 Wifi tablet (v400) 2 weeks ago. Came with preinstalled Lollipop android so i couldnt install a recovery rom to flash any other custom roms. Downgraded to Kitkat version following the instructions on Xda forums and succesfully installed Twrp. When i installed Cyanogenmod 12.1 through Twrp i got stuck in fastboot screen.
Any suggestions and / or solutions would be greatly appreciated.
I had a similar problem.. Only mine was stuck at the bootloader. Go in TWRP and repair /data and other partitions. My data partition gave me an error since F2FS is a little flaky and some ROMs corrupted it (claimed they supported it). I would recommend erasing the system, cache and data partition if you can't get into TWRP.
The problem is i cant get out of fastboot whatever i try. It says start on bootloader but the tablet just restarts on an empty screen doing nothing.

if you have an sd card, try removing that, then reboot.
if that doesnt work, try entering fastboot command, fastboot continue
Tried without sdcard and i get the same fastboot screen.
How can i give any commands? The only options i have are Restart Bootloader / Restart / Power off. Tried restarting bootloader but i get nothing in return tablet just stays on with nothing on screen.

you said it was stuck on fastboot, if thats the case, install any needed drivers on your pc, connect device to it, open a terminal in the fastboot dir (after you go get fastboot), then try those commands i gave. you could also try, fastboot reboot dont think i mentioned that before.

Did as you said but every command i gave gives me an error message in adb terminal. There are new lines in fastboot menu in tablet now. Bottom two are SECURE BOOT - enabled & LOCK STATE - locked.

hmm, ok, im guessing it would have said that normally, when not broken. all the command does is try to release it past where its stuck. it doesnt actually flash, lock, unlock, or change anything.
imo, this seems good, because now we know fastboot is working.
i own lg devices, but not your specific device. i would hate to give you some bad advice and make your tablet broken more, but if it were me in this situation, i would try to flash the factory KK firmware you used to downgrade with odin or however you did it. hopefully, that will clean everything up and let it boot properly.
if for whatever reason you cant do that, we could try extracting the factory file, and just flashing recovery and system, those should be the only things that got changed putting on twrp and cm normally.
Sorry, I have the serious proplem wtih my LG pad V400, I rooted it and using <LG Flash Tool 2014> with <V40010c_00.kdz> to downgrate the firmware but their is error then my LG pad stuck in fastboot menu as with just turn off, restart and restart bootloader. if i seclect one one them the tablet just logged again the fastboot menu
it stuck on the fastboot menu and i cannot do nay think with it. I can restart with factory restore mode but when select yes to restore, it will restart and log in fastboot menu again.
I downloaded adb and fastboot program and put in one folder <Minimal ADB and Fastboot> in C:\Program Files (x86)\Minimal ADB and Fastboot
I dont have recovery image so i download file <cm-13.0-20160421-NIGHTLY-v400-recovery.img> form your link to download TWRP file
move it to folder of fastboot programe and changed its name to <recovery.img>
I turn on the tablet and it waited at fastboot menu
when i run the command <fasboot flash recovery recovery.img> and they said some thing wrong like in picture
please help me
