Hi I have the following problem: after I flash Cannibal open touch recovery I could not flash any .zip file so I decided that I go back to CWM touch so I restarted my phone. Phone booted into fastboot mode with the following message no boot or recovery IMG so I decided to flash recovery with fastboot. I opened the folder with fastboot command flash_recovery connect the phone to usb but the command line always showed waiting for device. I unplugged the phone and tried to press the volume keys but nothing happened as if it freezes. I pulled the battery and try it again but no response. I cant connect phone to odin because it has broken power button and after I insert the battery it always turn on itself. Please advise me what to do thank you.
Seems your drivers have gone corrupt. Try a different system and use Nexus Root Toolkit.
I tried this option but without success. Phone does not respond to anything. No volume up or volume down. It´s just stucked on bootloader.
This link says that if you get <waiting for device> , then fastboot is not configured properly. Check out the link over here.
You may also try this command "fastboot boot recovery-clockwork-6.0.4.3-crespo.img" to boot into recovery without installing it.
no hope
The reason you cannot navigate in fastboot/bootloader is that your powerswitch is probably stuck in the "on position"...does your device immediately power on when battery is inserted?
The way i solved this a few months ago was to completly remove my powerswitch from the board power my device on..use quickboot to enter fastboot menu and input commands...
Also completely removing your power button makes powering on your nexus alot more complicated.
what i did was go to download mode (holding vol+ and -) and pluging phone in..this takes you to download mode
then you need to get a copy of a boatloader file to flash via odin which will reset your phone and power it on...pm me if interested i can provide you with files necessary

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)
try this:

Firstly, the power button has gone faulty on my Nexus S and I am due to send it back to Samsung for repairs, so I want to get it back to factory image 4.0.4 IMM76D using the Google image and to relock the bootloader. However, when I reboot into fastboot all the keys stop working and I presume it has stopped responding and the only way to reboot is to do a battery pull. Just wondering if anyone has had this experience before and knows a solution.
By keys you mean volume and power right?
Does a computer recognize it with fastboot. Example . Fastboot devices / fastboot reboot etc?

Volume and power keys don't work while in fastboot and it isn't recognised by that. And when it powers on regularly it say No boot or recovery img. Nope, doesn't get recognised by PC and just says No devices found...
Did it work before in the same system?
Only other thing I could think of to try is download mode/Odin
It was working fine that day. I even flashed CWM on it after trying TWRP. But then suddenly the power button broke, and when I used the key combo to get into fastboot mode using the plug in to charger method it loaded fastboot and just wouldn't respond
Hey guys, so I have this dilemma on my hands. One of my friends has a Nexus 5 that has a power button issue. It seemed like a stuck power button, because even cleaning it did not solve the issue. So I removed the power button, and it finally turned on. However, it's now stuck in a Google logo bootloop.
The Objective:
To recover all data on the device. This is a must.
The Obstacles:
- No physical power button, but I can place a pair of tweezers on the terminals on the board to simulate a power button press.
- Bootloader is locked (I can unlock it, but that erases all data on the phone).
- Cannot enter proper stock recovery (I get a "no command" error when I do; I've tried all button combinations afterwards, including the ones from HERE, but to no avail).
- USB debugging was not enabled on the phone when booting normally, so even though the phone is recognized by my PC, I cannot do anything using ADB.
- Fastboot mode is the only successful mode I can reach on the phone.
The Final Question:
Does anyone know how I can successfully recover all the data on the phone using ADB or any other method, having the above obstacles?
Thanks in advance.
If you can reach fastboot without any problem, you can try to boot a custom recovery image using the following command : fastboot boot recovery yourcustomrecovery.img
(if you dont have a custom recovery, you need to flash one with : fastboot flash recovery yourcustomrecovery.img)
It will boot in recovery mode and, I hope, allow you to have an adb access and recover your data.
edit : since your bootloader is locked, i guess this won't work.

I bit of a trick. Try 'fastboot flash boot recovery.img' but instead of kernel flash twrp. After flash do a 'fastboot reboot'. It will boot recovery. Via twrp the pc will recognize phone as a media storage. You will not erase any data

Thanks for the response, but the bootloader has to be unlocked for that to work, and while I can do that, it will wipe the data I need.
*accidently put this in the wrong thread, if a mod could move it. thanks*
So I wanted to get rid of the chinese recovery that was on my lenova tablet and messed up along the way.
I first enabled debbuging USB on my tablet and used adb on my pc to boot my tablet into fastboot (I am unable to enter fastboot any other way).
I ran this line: "fastboot oem unlock" and then "fastboot flash recovery twrp.zip".
The TWRP version i flashed onto the recovery was a wrong version causing my tablet to go into a bootloop on restart.
I get no response from vol up+power, vol down + power, vol up+vol down+power.
I had to let my tablet battery run out since the back battery is unremovable.
The tablet shows the splash screen when it boots and restarts after about 5 seconds.
I have no idea on what to do so i turn for help here
First, you’ll need ADB and fastboot, which can be downloaded here. To set up ADB, go to Settings/About Phone/Software Info and tap on build number until you get a toast notification saying “You are now a developer!” You will now have a new category in Settings called Developer Options. Go into developer options and enable USB debugging and OEM Unlock. You won't be able to turn it on if your phone is plugged in to your PC. Once you've turned it on, go to your PC, open Terminal or Command Prompt and type “adb devices”. Then plug in your phone and hit enter. You'll get a prompt on your phone to “Allow connections to this PC?”. Check Always allow and Allow. Now run “adb devices” again. Your device should now appear in Terminal.
If you have a SD card, download the latest zips from here and here onto your SD card. It'll save you a step later on.
Then you'll need to reboot to fastboot by holding down VOL- and plugging in USB while power is off. Alternatively, you can type “adb reboot bootloader” in Terminal or Command Prompt.
Next, you'll need to unlock the bootloader. Bootloader unlocking will factory reset your phone! Once you're in fastboot, run “fastboot oem unlock” in Terminal or Command Prompt. Now the bootloader is unlocked.
Now it's time to flash TWRP, a custom recovery for Android. It's going to be the way you install custom ROMs and add-ons. Download Official TWRP here. Once you've extracted the recovery.zip, run this command: “fastboot flash recovery path/to/recovery.img”. Once the file has flashed, disconnect the USB cable and battery. The next step is important! You're going to need to boot into TWRP for the first time. With the phone off, hold down VOL- and press power until the phone vibrates and the LG logo appears. While still holding down VOL-, release and immediately press and hold power. You should now be at a white screen that says “Reset all data and restore to factory settings?” Use the volume and power keys to select yes and yes again. If you've installed TWRP successfully, it won't actually factory reset your phone. Now you should see the TWRP screen. If you don't see the TWRP screen and instead see a floating ring that says “Erasing”, don't worry. Let if complete and try flashing TWRP in fastboot again.
In TWRP, you'll be greeted by a screen that says “Swipe to allow modifications?” Swipe it, then go to the Wipe tab. Go to Wipe, then Format Data, then type yes, then go to the Reboot tab and select Recovery to reboot into TWRP again. If you're prompted to install the TWRP app, don't bother.
Once you've rebooted into TWRP again, it's time to disable encryption and root the phone. Download the latest zips here and here. Skip downloading them if you already put them on your SD card earlier. On your PC, push the files to your phone using the command “adb push path/to/file.zip /sdcard/”. You can drag and drop the file into Terminal or Command Prompt to copy file path. Then go to the Install tab in TWRP and select the no-verity-opt-encrypt.zip, tap Add more zips, then add the root zip, then swipe to flash. Let the zips flash, then tap the Reboot System button when it's done. Your phone will take a little longer to boot and might reboot a couple times.
Once you're back in the OS, go through the setup wizard. Set up Magisk. If you stay on stock, you should install an app like Quick Reboot Pro from the Play Store to make it easier to reboot into recovery. Now reboot back into TWRP and go to the Backup tab. If you have a SD card, set it as the backup location. You can enable compression if you want. This will make a full system backup that you can restore from as long as you have TWRP. If the backup takes up too much space, you can put it in Google Drive or your PC later on.
You are now ready to install ROMs!
Thanks to @messi2050
My device will not start boot loader with command "adb reboot bootloader" or with the method of holding volume down and pugging it into the PC, it just restarts and boots like normal. i cannot even get to the stage to use the command "fastboot oem unlock"

Please explain more in detail so you can be helped better In what ways? What are you doing to get into bootloader mode? I've never had any issues on my T-Mobile Stylo 2 plus. Are you trying to get into bootloader using buttons manually or through twrp or adb?

You hold volume DOWN and power then soon as screen comes on and you see LG you let go of the power button and then immediately press power again and you never let off volume DOWN. That doesn't work?

Hey there, I've got the LG K530F, is there any chance of unlocking it? I looked up the LG developer website and it's not listed in there, filling that form will just lead to a popup regarding that. I thought about downgrading it back to MM (Android 6.0) using the K350F10d_00_02221.kdz firmware package aiming to be able to run fastboot oem unlock, but I'm afraid of getting it bricked. Anyone tried it? I recall doing something like that to unlock the LG Optimus L9, but that one was way older and had much weaker security measurements.
Can't get into Bootloader
Hi i have a LGL82VL and when trying to use adb reboot bootloader it just restarts, And when using Vol Down and Power it just comes to the factory reset page (Hard Reset)
Any ideas on how to get to the bootloader? i checked with fastboot devices while on the hard reset page and got nothing. Any Ideas?
