Last night I was on my nexus before I would go to bed. I opened the franco kernel app and then noticed that r6 was available for download. I downloaded and flashed it and was about to go to sleep when I noticed the notification light that my phone was charging. I thought it was neat then tried to get some sleep, but my promised sleep did not come quick. After a good chunk of time had passed, I thought that my lack of sleep was caused by the green light that was barely noticable. I searched and searched in the app to try and find an option to disable the LED, but could not. I then decided that the best way to get rid of the light, would be to flash the older r5 kernel so I wouldn't have to see the light anymore. I hit flash and my phone rebooted and then brought me to the bootloader. I attempted to reboot but I could not. I've tried using adb and nexus root toolkit to get my device to work again, but they can't seem to find it without the correct drivers. I installed Motorola device manager, nothing. I tried to follow the instructions in the toolkit to get the correct drivers installed but I can't continue with the need to enable debugging, which I cannot do from being stuck at the bootloader.
Under bootloader logs, I have the following messages:
Invalid boot image size!
failed to validate boot image
Fastboot Reason: Fall-through from normal boot mode
Any help would be greatly appreciated.
USB debugging is an android setting. It can only be used when android is running. If you had USB debugging on, it would make absolutely no difference in recovery or bootloader so don't let that step stop you.
From the logs, it sounds like your kernel download is corrupt or didn't flash properly. I had a similar message when I flashed a partially downloaded recovery image today.
Just fastboot flash a complete boot image
I tried that last night by launching adb and doing 'adb devices' but my device is unrecognized and I am unsure of how to go about fixing that.

Tried what exactly? Adb and fastboot are two different things. Adb works in android or recovery only. Fastboot works in boot loader only. Boot to boot loader and do "fastboot devices"
Ah that was my mistake. But the fastboot devices command just returns a new line for a new command to be entered in

That probably means there is a blank line between them - showing that no device is found. Unlike Adb it just gives a blank line instead of "no devices".
Probably means a driver issue or cable issue. Try different USB ports / cables if you can. Check to see if there are any yellow triangles in device manager too.
I'm new to this phone so I don't know where the drivers are if you need them. If I ever find them, I'll port my nexus 5 Adb and fastboot thread over here. Unfortunately i use Linux at home so I don't really have a driver issue.
Oh, so if I were to use Linux I wouldn't have to deal with missing drivers? I'm assuming that's the issue since no matter which port I use, 'Connect USB Data Cable' doesn't change

I can't say for sure. In Linux you may need to add UDEV rules. I didn't though. My bootloader is just recognised.
Please do check your device manager though.
I'm sorry i can't help more right now. I'm going to bed.
Okay, thank you! I'll reply if I encounter any other errors!

I am not new to flashing phones, but I cannot figure this out. I can run Mofo and Mofoverify, but I cannot run a fastboot commands like "fastboot flash logo logo.bin". All I get is waiting for device. " Adb devices" and "fastboot devices" both return an empty list in there respective modes. Now I have tried several similar but not the same fixes from many Google and XDA searches. I have tried all sort of driver solutions, USB cables, toggleing of settings in my phone and such. I have used Mofo without issue and still can, but fastboot won't let me flash the setup files for Lollipop and I want me some sweetness! I have a newer Windows 8.1 machine and the XT1254. Lastly, this is my first Q&A thread post, so please be gentle. Thank you ahead of time, because this is XDA, and it can solve anything!

Any way you could try it on a Windows 7 machine?
Where did you get your fastboot files? If mofo detects it then your fastboot files are jacked up
Go here: http://dl.google.com/android/android-sdk_r24.3.3-windows.zip
Once you extract it, run SDK Manager, Select to install Android SDK Tools, Platform-Tools.
Once that's done, go to \android-sdk-windows\platform-tools. Hold shift, right click and Open Command Prompt. Then fastboot will work
O
Here's an easy way to install Fastboot/ADB.
Once that is installed you'll have to change your commands to fit the file path of the fastboot files.
For example:
Code:
fastboot flash logo C:\Users\OP\Desktop\logo.bin
[/COLOR]

This minimal version of fastboot is a lot smaller and worked for me.
I have used minimal Adb/fastboot. I don't know if it helps, but when in Android, even after revoking USB debugging authorizations, I never get asked on my phone to re-authorize my pc. As for a Windows 7 machine, I could downgrade my laptop, but I wanted that to be a last resort.
@savage- sorry for posting this on ComputerFreaks thread, but it was his image I am trying to install and figured someone doing the same as me may have had same issue, but I'm sorry.

A windows 7 machine is unnecessary. I used windows 8.1 pro x64 to perform the whole upgrade process without a hitch. If mofo functions correctly, that means the fastboot drivers are installed correctly. If you start up minimal adb/fastboot, plug in your phone while it's in fastboot mode and type "fastboot devices," what do you get?
EDIT: Duh. You already said that it says returns nothing. Well in that case there has to be some sort of problem with the USB connection or the minimal adb/fastboot installation. Maybe try running the minimal adb/fastboot shortcut as administrator. I don't remember having to do that on mine, but who knows?
St33ve- see OP, nothing listed for adb or fastboot devices commands in their respective modes.
Have you tried a different USB cable?

Yes, about 7 different ones. 4 that I am sure have worked before, and no physical damage to them.
You said Mofo is able to see your device though, so that's kind of throwing me through a loop. You could try a fresh install of the Minimal ADB, and double check your drivers?
That's a sign of drivers not being installed!
Try opening up device manager n see if the driver is not installed.... If u see a device with an exclamatory mark n "quark" somewhere in it... The drivers aren't installed...
When the phone is in fastboot mode, the phone is listed as quark fastboot, but no exclamation mark. I reflashed computerfreaks image (KK) without an issue, but still isn't recognized in fastboot or Adb. I really want to flash me some Lollipop! I have crack flashed with every phone I own. I'm going thru withdrawals here LOL.
i am having the exact same issues. I've reinstalled drivers, switched usb cords and have had no success.
I'm not certain what actual fixed mine because I tried so many things but I got mine to recognize my phone. I think what did it was revoking the USB debugging authorizations and deleting the adb files on my computer under username/.Android. Then reauthorizing my phone. That and I believe I may have had duplicate drivers interfering with each other. Hope this helps
Hallelujah, I have lollipop!!!
I do not know exactly what the issue was but after factory resetting windows 8.1, and manually loading each driver for adb and fastboot, it works (again). I wish there was a Thank All Button. THANKS ALL!!!
After installing the "15 seconds adb installer", I shift clicked the folder with my twrp file, "twrp-3.0.2-0-tbltetmo.img" to open the command prompt and type in "adb reboot bootloader" , causing my screen to go into boot loader mode. [ e.g. image ] ]So far, everything is going well, according to this guide.. However, the problem is the next step. Once in boot loader mode, i type in "fastboot flash recovery twrp-3.0.2-0-tbltetmo.img" . Instead of masses of text appearing, I instead receive the message: "Waiting for device." To be honest, I think my problem lies in the fact that before i went into boot loader mode, my phone was detected by my pc, but after it shifts to boot loader mode, it stops being detected, this causing the "waiting for device" message. However, even though I know the cause, I can't find any means to fix it after searching for hours. Also, yes, I enabled allow unknown sources and usb debugging. I've also went to T-Mobile's website to install their usb driver.

Possibly the cable. Not sure if the USB drivers you got from T-Mobile's website are the same as the one that TEKHD posted in his Tutorial thread for rooting...but I use those and with my original cable. (sometimes with my Xbox One charge cable) Hope that helps.
I know that if I use a a cheap or thin cable, I get problems.

Thanks for your reply. I gave up using the usb cable method to connect to adb. Instead, I just flashed it with Odin, which works (strangely, even though my device still didn't appear under "Computer")
I received my new sony 1 ii and have checked and the bootloader can be unlocked and the phone can be rooted. I thought I was away to the races but I'm mystified. I can't get the phone to boot into fast boot.
I appears I have the drivers in place and the phone is recognized by the computer but no luck with fast boot.
I have searched and can't seem to find out why this is. I suspect some kind of driver issue with win10 but when I connect to the computer with the phone off and hold the up-volume nothing happens. I have also tried to boot into recovery mode and that does not work as well. Any help would be appreciated.

On Sony devices you need to power off and hold volume up and plug in the USB cable. That should leave the blue LED to indicate fastboot mode. I'm not 100% sure since it's been a while since I've messed around with Sony devices
Thanks for the input. I have done that and am still unable to action ADB - It is a little confusing since the phone only shows the blue light and nothing else.
If I normally boot the phone it will register as an ADB device. I also find it strange that it will not boot into recovery. The android icon flashes but when you release it boots to safe mode. I assume it is a driver issue but it is not revealing its self to me . Cheers

The blue light is fastboot mode. There is no ui interface in fastboot for sony devices. Just a blue light and black screen.

Same person but had to change user name -- more on the issue
I managed to unlock the boot loader and it seems that at every step for rooting I am running into curve balls. Windows was not working for me so I managed to unlock the bootloader with Linux and going on to the next step I had to go back to windows to find a current factory ROM.
The next issue: going back to the "how to" I am unable to located boot.xxxxx.sin in the factory ROM and the closest I could find is boot_x-Flash-ALL-2389.sin and that doesn't work.
In the boot directory all files are bootloader_X_44 and a combination of zip and sin files
Can anyone steer me through the muddy waters
The factory rom was downloaded through XperiaFirm application

May I know how did you unlock the bootloader? Did you use xperia 1 as your device in https://developer.sony.com/develop/open-devices/get-started/unlock-bootloader/#unlock-code?
I have already installed usb drivers and have the platform tools. But everytime I boot my device to fastboot, whether using "adb reboot bootloader" or power button + volume up, screen only shows black (led is solid blue). I did left it for a couple of minutes, nothing happened.

Plug the device
Make sure adb can see my device
Use adb reboot bootloader command

I assume you are using windows and I must say I gave up trying to get win10 to work and I was stuck at the same place you are. I then switched to linux and it went a lot smoother and I didn't need all those tools as laid out in the description.
In linux you must use the phone to go into fastboot mode if you boot from computer it actually boots to a visible screen on the phone and I didn't have connection that would take the command line commands. Linux is very good because if you are missing something it will give you a link or a command line input when you execute the ADB or Fastboot command.
I have run a windows/linux dual boot desktop for a while now and I'm no expert but coming from the era of command line I can muddle through. Sorry if I can't give you more info on windows but win10 is such a pain and I find that with a lot of things linux works better. If I didn't need adobe acrobat I would not even bother with windows.
cheers

I was reverting my phone to unroot and locked bootloader. And it is saying that "Your Device is corrupt. It can't be trusted and will not boot" loop.
I tried flashing it using the new flasher. But after flashing, it will do SONY boot loop. If I connect it to a charger it goes back to "Your Device is corrupt. It can't be trusted and will not boot" loop.
I can't use Sony Companion since it is saying that my battery is low, and I can't charge the phone since it will just continue looping.
Do you know/have any recovery.img?

First, you need your bootloader to be unlocked. It's pretty easy if you have that done already.
You'll need ADB and Fastboot. It can be tricky to get the right drivers. The driver used when your phone is connected in normal mode is not the same when connected in fastboot mode, in my experience anyway. You'll want the 15sec ADB driver and you'll need to update the driver when it is in fastboot mode.
Next, get the correct twrp img and put it in the ADB folder(you'll need a different one based on flashing a pie rom or a q rom). You may want to rename it so it's easier to type in fastboot.
To enter fastboot mode, hold volume up and plug in the usb cable. The LED should light up blue.
Open a command prompt and navigate to wherever you've installed ADB(mine is on C:\ so it's really easy).
Type "fastboot devices" to double check if the driver is installed and your phone is connected in fastboot mode.
------It should show something like: BH9090808E fastboot
Then type "fastboot flash recovery twrp.img" - or whatever you've named the file. It will take less than a few seconds.
Then type "fastboot reboot" and let your phone reboot.
Done
Thanks a lot for the reply!
I've been experiencing the exact issues you described. I'm having issues unlocking the Bootloader. "Fastboot.exe devices" does not show anything, the phone is with a blue led on and a balck screen and when I look in Device Manager there's an "Other" Android device with an "!".
Could you please share the drivers you mentioned? Because I really went through
everything and none was accepted. Also the 15 Seconds ADB Drivers did not help.

My apologies. It's been so long since I've started from scratch, I must've gotten the drivers mixed up. The 15sec ADB is for the phone connected in normal mode.
I'm pretty sure this one is the fastboot one:

If not, I'm sorry because that's all I have.
I nailed it eventually!
For anyone that comes across this thread,
this video will solve all your problems with adb drivers:
I'm a newbie at this but managed to stumble through installing CM 14.1 on my LG G2.
Phone: LG G2 VS980
CyanogenMod version: 14.1-20161207-unofficial-phoenix-vs980
Kernel version 3.4.0-crdroid-g0f70b4b
TWRP v2.8.6.3 (I don't know how this version got installed, I started out with a 2.7 version and upgraded to a later version but this is the version I see after I got CM installed).
Latest version of ADB and Fastboot from the platform-tools download.
I'm trying to make the phone automatically turn on when plugged into a charger using the " fastboot oem off-mode-charge 0" command .
ADB commands work fine.
If I issue the command "adb reboot bootloader" when the device is booted in CM I get rebooted into a black screen with the following:
"Firmware Update Do not unplug the USB connection until the process is complete." There is a progress bar that remains at 0%.
Any fastboot command I issue returns "waiting for any device". I have to hold down the phone power button for several seconds to exit this screen and then the phone reboots normally.
If I issue the "adb reboot bootloader" command when the phone is in TWRP or I select Reboot - Bootloader from TWRP the phone just reboots into CM.
What am I doing wrong?
Thanks
I'm not too familiar with this phone, but all that I know is that it is in download mode, which is not the same as a bootloader. As a lot of android phones aren't the same as each other, I am not aware of how to boot into a bootloader of this phone.
I will say though, if it is anything like a Samsung phone, then it probably does not have a bootloader and the only way to interface with this mode is through the LG Flash tool found here: https://lgflash.com/LGUP/
Don't take my word for it, but it is possible that this is the case. Again, I don't have any idea how the phone works or anything, but this is possibly the solution.

I believe I'm in download mode when I'm seeing the black Firmware Update screen. I'm not trying to flash a ROM at this point so I don't think the LGUP program will be helpful.

The meaning and purpose of Download mode, Bootloader mode and Fastboot mode are same.

1st thing of all things in order to run Fastboot commands is you have to run command
Code:
fastboot devices
what establishes the USB connection. As long as the connection isn't established Fastboot throws message "waiting for any device".
BTW:
Booting into device's bootloader ( FYI: each device has a bootloader ) requires in addition to the well-known Fastboot driver the Android USB Driver got installed, too. This driver is OEM ( brand/model ) specific, you have it to obtain from OEM - mostly offered on their website.

Not the same really - and LGs aren't Samsungs, or whatever either...
One maybe could try emptying LAF partition ("nuking"). Some more drastic ways also suggest it for boot as well. But IDK, is it worth the trouble really? And even if one could get into the fastboot, that command might not work after all...

The meaning and purpose of Download mode, Bootloader mode and Fastboot mode are same.

The way I get into download mode is to hold the volume up button and plug in the USB cable with the phone off. When I do this I briefly see a screen that says Download with a blue hashmarked bar below it. It then goes to a screen that says "Firmware Update Do not unplug the USB connection until the process is complete." with zero percent progress.
Should I be able to issue fastboot commands when the phone is at that screen?

I'm trying to repurpose the phone as a dedicated Android Auto "server" and would like to be able to leave it connected to my car. It would be really useful to have the phone turn off when there is no USB poser and turn on when there is USB power.
If I make a backup of the Boot and System partitions within TWRP would that allow me to restore my LAF if I nuke the LAF and something goes awry?

>to have the phone turn off
Could it be there some app for such? IDK, maybe...
>If I make a backup
Nope again, The LAF has a partition of it's own. To backup use lglaf.py or LGUP having the dump option enabled or extract it from kdz if available.

This is probably a bridge too far for my skill level.
Is there a work around like putting it into a deep sleep that will let the battery to last for days or weeks but wake up when the USB has power?

There's probably a way to do this via root and there will probably be some app that lets you do this. Other than that, you'll have to dig around and see what you can find.
