Database Develop

I can NOT get ADB to recognize this phone in fastboot mode.

Please for the love of god help me. I've tried everything.
I have a developer edition. I have the newest drivers, the newest phone updates. Everything. It is recognized by ADB when I'm on the home screen, but when I am in fastboot mode itself it will not recognize the device. I can't unlock the BL because of this. It's VERY frustrating and I'm about 12 hours from selling this device and buying an HTC M8.
I have Windows 7 64 bit. I'm on the newest moto drivers, the newest FW for the X. I've uninstalled and re-installed and restarted my machine countless times. With no luck. With the drivers installed I booted the phone into fastboot mode, pulled up a command prompt where ADB was installed, ran adb devices and nothing. Over and over again. Please help me. I really want to keep this phone.

Navigate to where fastboot.exe is installed, and run "fastboot devices".
And make sure phone is in bootloader mode.
Does it list serial number?

I ran into the same issue last night, I just got a moto x DE for my wife, and a new laptop since last March when I unlocked my moto x DE. "adb devices" returned nothing, and I had a fresh install of the SDK and the moto drivers. Both old and new laptop on Win 7 64-bit. I googled trying to find a solution, but didn't find anything that worked. Grabbed my old laptop, hooked up to it, and it worked fine.
One suggestion I saw and didn't try was to remove/reload the moto drivers. Since I got it working and got her phone unlocked with my old laptop, I didn't pursue further.

Adb devices wont work when the phone is in Booloader/fastboot mode.
Make sure you have the latest Moto drivers from here -> https://motorola-global-portal.custhelp.com/app/answers/detail/a_id/88481
Follow this -> http://mark.cdmaforums.com/ADB.htm To install The Android SDK, PlatformTools, and mFastboot, and add platform tools to the Path.
once that is done.. type fasboot devices and see if you get anything. If no, look at Device Manager and make sure there are no ! or such in there.

This is what worked for me. Posting here for posterity and potential helpfulness.

I hit the issue earlier and fixed it with the steps. hope will help you too.
1. connect your phone with computer
2. go to C:\Program Files\Common Files\Motorola Shared\Mobile Drivers\
3. run Motorola Driver Installer.exe, choose clean and Reinstall.

Even that wouldn't help him if he was trying to use adb while in the bootloader.

Thanks for clarifying. I only end up dealing with rooting something once a year or so and always forget the "ins-outs-and-what-have-yous". Once I was reminded of fastboot vs. adb all was well!

[Q] Bootloader Troubles

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!

The Google driver works for all Nexus devices (except the GNex): http://developer.android.com/sdk/win-usb.html

Connection issues between computer and Nexus6

I bought a Nexus6 about a month ago. I wasn't planning on rooting it, but I have rooted a number of devices in the past so am reasonably comfortable doing that. I bought the phone from Amazon but I am on T-mobile's network.
After I fired up the phone and used it for a while, I got a message asking me to update to software version 5.1. When I go to the about on my phone, it says it has 5.1.1 but it says the build number is LRX22C which when I looked that up indicates that it is actually running 5.0. I told the phone to update, but it fails every time (android guy with the red exclamation mark over his belly). I did a factory reset and repartition and still the same thing. At this point, I figured I would just root and and force it to 6.0.
After installing drivers, ADB-tools, etc. my computer recognizes the phone. When I connect by a USB cable and the phone is on, it shows under devices. However, when I boot into fastboot mode, my laptop no longer recognizes the Nexus. The fastboot screen shows that the phone is unlocked, and it recognizes that it is getting power from the laptop. However, it says to connect via usb. Running the command prompt and using SDK-Windows, when I type fastboot devices it shows nothing.
Interestingly, I see that Superuser is on the phone and working. I don't think I rooted my phone at any point in the process of trying a lot of different things, although anything is possible. I have been thrashing around a bit trying to get this to get the phone on 6.0 so might have rooted accidentally although I doubt it. My suspicion is that I was given a previously used phone that someone rooted and returned.
Any suggestions/help out there?

When in Fastboot Mode, what does Device Manager show? Does it see the device correctly, or is it showing a yellow triangle w/ exclamation point over the device?

It shows Other Devices > Fastboot Shamu S with the yellow triangle and exclamation point. I have motorolla device manager installed and I thought that had my drivers covered but perhaps not?

These devices do have driver issues. Try downloading the correct drivers and it should fix it, a lot of people have had similar issues.

@LSquared
Download Wugfresh Nexus Root Toolkit. It has a long button on the top right "Install and test drivers" - a really helpful guide in clearing out any old drivers and installing and testing the new ones.
It can also perform many other functions, but after a lot of persuasion(!) in these forums I decided that learning to do everything manually is not only simple but safer, because you know at exactly which point an error occurs. The driver setup part of NRT is a brilliant help in setting your PC up once to get you started.
If you don't have anything valuable on your device yet, install the MMB29S factory image, then TWRP, and from there install SuperSU v2.66, and you're as up to date as you can possibly be.

Spend a few hours doing research and you will be fine. Just stay away from root kits. They only make things worse and lessen the experience of owning a nexus. As well as stops any help you may get in the forums as no one will help those that use the root kits.

Thanks for all the help/suggestions. After a lot of poking around, I realized that I had the right driver hiding in a folder (inside SDK I think) and had to just manually point to them and that got rid of the connection issue. Now I seem to be stuck on flashing the latest stock OS. I have been trying to flash via Minimal ADB and Fastboot but it isn't pushing the image there correctly. I don't want a custom rom, just stock 6.0.

How are you trying to push the files, I assume Fastboot, are you getting an error? Is your Android SDK up-to-date?

Google updated fastboot a little over a year ago to allow flashing the very large system.img files. Minimal ADB & Fastboot does not have this update (I believe). Download the latest Android SDK and you'll be good to go.

I just downloaded Android SDK so it has the latest files (I believe). Android SDK doesn't connect to the phone, it just keeps an updated set of firmwear, right? If I am not using minimal ADB and fastboot to push files from my computer to the phone, what program should I be using? It seemed a lot easier on my older phones that had a micro SD card because I could just drop the new Rom on there and install that from the bootloader.

Use the ADB and fastboot that are included with the Android SDK that you downloaded. They are in the Platform-Tools folder.

That guide is great and helped me get the bootloader unlocked and the phone rooted. I downloaded the image file just fine, but when I go to run root-windows.bat I get the message "fastboot is not recognized as an internal or external command." I am guessing I don't have some file in the right location?

The flash_all scripts don't work. Flash each img file individually, after you've extracted them all from the ,zip.

Yup, flash the .img files individually, the batch command doesn't work.

Here's the guide I always use: How to manually flash img files to your Nexus device
Basically, with phone connected to computer and booted to the bootloader, open Command Prompt window, change directories to where your sdk/platform-tools directory is with your Shamu files, then:
Code:
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
Code:
fastboot flash bootloader "name of bootloader"
fastboot reboot-bootloader
Code:
fastboot flash radio "name of radio"
fastboot reboot-bootloader
NOTE: You'll have to extract the files from the image-shamu-mmb29s.zip file in this case to flash MMB29S.
Code:
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash cache cache.img
fastboot flash userdata userdata.img
Code:
fastboot reboot
I'm aware, it may be overkill, but I've never had any issues performing all of these steps to get back to 100% stock so if it "isn't broken, don't fix it". Also this will wipe your internal SD area, so any files you want to save you should save them prior to starting this.

Good summary!

To avoid wiping your internal user storage, just skip the step that flashes userdata img (and the step at the beginning that erases usedata)

Booting TWRP through fastboot doesn't work

Hi guys, I got a new XT1900-7 today, tried to install TWRP but I'm not able to boot it with "fastboot boot boot.img".. Yes the bootloader is unlocked, cmd is running as admin, adb and fastboot stuff is correctly installed, motorola drivers are installed, tried different cables and ports... I don't get it why it does not work and I'm absolutely NOT new to this business... Additional info: Running OPWS27.2.4, patch level August 1, 2018.
See the cmd screenshot below, it freezes there... Any help is much appreciated, absolutely don't know what is going wrong here!

What's the file size of your boot.img? It should only be about 30 mb. It's not frozen it's still attempting to transfer the img to your device.

Thanks for your reply, the file sizes are correct, I tried these from twrp download page: twrp-3.2.3-1-payton.img (29.5M) and twrp-3.2.3-0-payton.img (25.9M) - same result.

Ensure Motorola drivers are up to date and even try a different USB port.
With Windows, does it see the phone in device manager while in fastboot?

Latest drivers from Motorola Device Manager are installed and phone is properly recognized in device manager (used usb 2.0, 3.0 and 3.1 ports, nothing changes, same behavior). I tried it now with mfastboot but still nope..

Are you using minimal or full sdk (by Google) platform tools?

Minimal, I have also a Moto G5 and I don't face this kind of problems - only with Payton.

I recommend switching to full sdk. You don't have actually download all the packages, just the platform tools and it keeps itself updated. I stop encountering these random issues when I switched from minimal two phones ago. Issues like yours are; 9 out of 10, driver issues.

The very next thing to try, would be reflash everything.

Unfortunately still no progress with full sdk and latest platform-tools, I'm giving up (for now).. I don't get it man, I'm not able to do anything in bootloader... for example when I try "fastboot flash partition gpt.bin" it freezes at sending OR it throws instant failed, the bootloader log menu shows that something is downloading but nothing happens... I relocked the bootloader (locking and unlocking is no problem) again and I am going to use it for a while... otherwise I will do a mistake somewhere and will brick it... Thanks for taking the time to help me haha

I'm having this same exact issue, just got this phone (XT1900-1) for my wife and she wants a custom rom, my own phone booted into twrp no problem.

https://forum.xda-developers.com/moto-x4/how-to/guide-how-to-flash-official-factory-t3808348
Maybe try the fastboot in that link. I read through the thread and no specific reason why they suggest that version but it allowed people to flash back to stock. I used it last week to go back to stock before Lineage.

No effect still stuck on "downloading 'boot.img'..." but thank you, should I try flashing TWRP without booting? Would that even work?
or maybe an alternative way to get TWRP like a rooting method or the such?
Edit: Im going to try a factory reset, who knows maybe itll work?
^Nope
Edit 2: ERRR ota update is also failing to install, all I did was unlock the bootloader, havnt been able to do anything else.. wtf is going on.. What should I do from here, lock the bootloader and try ota again?
Edit 3: Something strange is going on, the fastboot commands are failing randomly I just noticed, see the attached image... Im spamming the same exact command once every second and it intermittently works.

Sorry, beyond my expertise. Maybe it's USB c port on the phone issue? Intermittently dropping the connection? Or have to tried flashing the 8.1 sick from the thread I posted? Maybe the factory ROM is messed up some how. I honestly don't know and those suggestions aren't based in any real knowledge.

Code:
fastboot version 1:7.0.0+r33-2
Android Debug Bridge version 1.0.40
Version 4986621
In linux mint do you have the same versions of the tools as above?

Had exactly the same behavior like you (especially Edit 3), I tried it on a different computer from 2013 with usb 2.0 ports and it worked..
No other cable, no usb port, no adb and fastboot changes and no other drivers - just put all the stuff on a other computer and run the commands from there :good:

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.
Thanks!

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:
