[Q] Fastboot Device not Recognized

I was trying to flash a new splash screen for my phone and I was getting the error below. I got a similar error when trying to flash a new kernel earlier this week. I always get the "FAILED (status malformed (1 bytes)) finished" error.
I have been searching for about three hours for a fix to this problem to no avail. Right now I'm thinking it could be my drivers, but I can't find HTC Sync for the MT4G. Also, I can use ADB and my phone is recognized there, which made me think it was not my drivers. Ugh, I'm just so confused.
Here is the error:
"C:\AndroidSDK\tools>fastboot flash splash1 rootedmytouchsplash.img
sending 'splash1' (750 KB)... FAILED (status malformed (1 bytes)) finished. total time: 0.021s"

Just to make sure, did you put your device in fastboot mode before flashing image?
What does "fastboot devices" return?

Yes, I was in fastboot. It shows my options in fastboot as (Bootloader, Reboot, reboot bootloader, and Power Down). When I input fastboot devices this is what returns.

Is your S=OFF?

My s=off. Otherwise I would get an error saying that the command is not allowed I believe. But yes, s=off.

fastboot.... you're doing it wrong... I would be glad to help, but troubleshooting over forums is annoying. hit me up on aim, yahoo, msn, gtalk, IRC, etc

I would also be hugely interested in a solution or fastboot instruction sheet. I have similar problems on my 4G trying to flash to stock Glacier 2.2.1 (post OTA).
Thanks!

Yeah, you're not doing something right. fastboot devices should return the serial number of your phone followed by the word fastboot. Your command returned nothing. Make sure you have the proper drivers installed. It will install new drivers the first time you hook up the phone while in fastboot, and those are necessary.

So yea I just had a breakthrough about 2 mins ago and thought I would share. I too had the same problem exactly to the T of what you where having. Then I shyte you not, I had an epiphany. While in bootloader on my phone not attached I clicked on fastboot then plugged my phone in(i am using Win7 Home 64-bit) and nothing popped up in my start bar. So I went to control panel and then to hardware and Right clicked on the Android hardware and updated my drivers automatically and viola my problem was solved.

I think I figured out my problem. When in fastboot, my phone isn't recognized by my computer. I went into manage devices, but Android Device isn't showing up at all. When I go back to bootloader, it recognizes my phone, and says its drivers are up to date. The only problem is, fastboot commands can only be used while in fastboot. If my phone isn't recognized while in fastboot, then I can't apply any fastboot commands. How can I get my computer to recognize my phone while in fastboot?

Are you sure you are in fastboot mode? I had the exact same problem and actually took the Nexus S back because I could not get fastboot to work(have to use fastboot to unlock bootloader). After reading numerous threads I booted my MT4G into recovery and cursored down to fastboot and actually clicked on fastboot and then connected the device to the usb which was already connected to the PC and lo and behold it loaded the drivers and away we went. I did the same thing with my Nexus one and my Vibrant and all now are recognized by fastboot. I do not know if this will help you but just wanted to share what worked for me.

Just had the same issue with my Incredible 2, followed the above, and worked just fine.

fastboot device is not recognized
Here' s my case
Initially unlocked bootloader, rooted through kingroot; tried to flash xposed framework through twrp but the zip file was not compatible. hence phone was bricked.
restored my moto g updated to 5.1.1 through OTA update.
Again rooted through Kingroot, bootloader is still unlocked but now when i'm trying to again install twrp i'm getting a message that
""'fastboot' is not recognized as an internal or external command,operable program or batch file.""
the procedure i'm following is correct. Prerequisite requirements are also installed.
Please help!

Help with rooting P8-lite Ale L21 dual-sim C432B564

I have a relatively new P8-lite L21 dual sim phone and I am quite happy with it. It came with C432B170 which is Lollipop I think 5.01. After a few days it updated to B172. I have unlocked the bootloader after registering with Huawei and waiting 2 weeks. Then I have successfuly rooted the phone with Kingroot phone version. Two or three weeks ago I have updated the phone to MM (6) and Emui 4 with local update (B560) that I have gotten from this forum. 2 days ago I recieved the notification of OTA B564 which went smoothly beside the fact that it reset the phone but i have succesfully restored (contacts, data etc.) All of this time since I upgraded to MM i have tried to root the phone but I was unsuccesful either with any software solution ( Kingroot, Kingoroot or others). After reading most if not all discussions on this forum and several blogs and how -tos, I tried the so called fastboot method others have recommended but here is now the gist of my problem. My phone is seen by my PC - OK so USB drivers are properly installed (by the way my PC is Win 10) and I have installed Android SDK as well as minimal ADB. When i try to flash TWRP 3.00.2 I can not do it (the message says something about not able to access or i think remote command not allowed. So since I cannot flash TWRP i am unable to put SU on the phone and root it. I hope someone more experienced and skillfull in Android world can point me in the right direction and help me. Thank you

Download mininal adb fastboot and then try to flash twrp via fastboot.
That error occurs because your adb doesn't have full permissions.
Minimal adb will solve this.

Downloaded minimal adb fastboot and installed it. Tried the procedure. Copied TWRP recovery to the minimal folder. Shift right clicked in the folder of minimal and opened command window. Adb rebooted to bootloader. Phone shows it is unlocked. The device is seen in fastboot window but flashing recovery doesn't work (same message) I am really confused. How do I give adb full permissions ?
Any way thanks in advance.

Did you activate usb debugging ?

Yes of course !

Try reinstalling drivers with universal adb.
Are you sure your bootloader is unlocked?
Type fastboot devices and let me know the output.

The drivers were reinstalled. My bootloader shows unlocked on bootloader (bottom of fastboot screen). Fastboot devices does nothing. Adb devices shows my phone serial number correctly (I have it written down). But then when i try to flash recovery it is unsuccessfull. It says "FAILED (remote: Command not allowed)"

sorry, if you've already answered this, but you can also do it by flashify... flash the recovery image via flashify (root needed though)

Weird... i can't think of anything else myself that hasn't been said. Perhaps... redownloading twrp? Maybe the image is corrupted by something... ot's a long shot because ot should flash everytging that comes its way. But it's the only thing you hven't tried.

LET ME EXPLAIN...
i solved the problem of not installing the TWRP by reading this topic here
https://forum.xda-developers.com/g6-plus/how-to/twrp-installer-zip-evert-t3875657
it seems that newer versions of TWRP cant be installed, instead i must type
"fastboot boot twrp-3.2.3-0-evert.img" and run it by the PC-DESKTOP.
but i saw another post saying this
segra246x said:
You can install TWRP on this device and it's very simple!
First boot TWRP via fastboot boot twrp.img and then flash the TWRP-Installer.zip in TWRP. This overwrites the stock recovery which is within the boot.img now for A/B devices. After that you have to flash the magisk.zip and it's done!
Just use Google to find twrp-installer.zip/evert

unfortunately the MOD APK dolby plus was flashed using TWRP but no app appeared when i started the android 9...
i installed twrp 3.2.1.zio(flashed with TWRP) after that i installed magisk v18.zip with TWRP.
i noticed that the internal partition of g6 plus was encrypted. and the partition of microSD CARD the TWRP reads perfect.
i entered in the android 9 pie system
i decided install and open the apk magisk manager 6
unselect the option "forceencrypt" and unselect the option "vdb verity mode"
the apk installed something and now my smartphone wont BOOT.
it is stuck on motorola logo in bootloop forever
when i try boot in recovery mode the TWRP menu appears but i dont know what to do to have my phone working properly again...
it seems that magisk changed the partition of boot...

UPDATE: PHONE WORKING WELL AGAIN...
Reading this topic
https://forum.xda-developers.com/g6-plus/how-to/3-how-to-install-root-aka-magisk-t3854244
i must type"fastboot flash boot boot.img"(the file boot.img from a stock ROM, I have the PPW29 116-16 ROM so i used it)

I don't think Dolby is gonna help your volume problem more than the built in one, try flashing magisk and installing the viper4android module.

Can´t boot twrp.img!

Hi,
I follow this Tutorial to root my Moto g6 Plus.
I could unlock my bootloader, but i cant boot twrp-3.2.3-42-evert.img.
When I try "fastboot boot twrp-3.2.3-42-evert.img" , I get
Code:
Sending 'boot.img' (31100 KB) OKAY [ 0.878s]
Booting FAILED (remote: '')
fastboot: error: Command failed
I am using Windows 10, 64 BIt.
I use cmd in WIndows Terminal.
I used the ADB and Fastboot Installer for Windows to install adb and fastboot.
Can someone help me please?
autowert66

I ran into this when I was looking to replace HavocOS 2.7 on Moto G6 plus and fix a few issues after a failed update using the tutorial here.
Did you disable lockscreen?
Even though this did not fix this issue for me it is well documented that it can have an effect on adb/fastboot use.
Did you see the notice on your phone to trust the connecting device?
I missed it the 1st time I tried using adb and it didn't prompt me again after that.
Have you tried adb/fastboot on another (older) machine .
I could NOT use fastboot on my Ryzen 7 linux machine w/ native USB 3.0 (or the 2.0 ports) and was getting the same type of results as you, although "adb reboot bootloader" worked fine.
I ended up usng an old HP Celeron laptop booting FWUL (bootable linux dev enviroment, Search for it here on XDA) on a USB stick which recognized the phone no problem and allowed me to "fastboot boot twrp-3.2.3-42-evert.img" (although I did copy/rename it to boot.img to save typing time), use it to backup to sdcard, format data, and install "new" ROM.
WARNING:
The tutorial I used above also has directions for installing (Open)Gapps and Magisk which, even after 2X attempts had lawnchair crashing continuously.
The 3rd time I just installed the ROM and Magisk and it's working fine.
This will be a test to use the phone w/o any g00gle at all (g00gle is EVIL).
HTH!

i know this is not a solution, but this kind of issue is solve by using a different pc.
i got the same "bug" with my current pc (ryzen 5 + motherboard asus b450m-a)
but my wife's pc (intel+asus mb) have working fastboot commands like usual
also try (if you can) using a usb hub... in my case it did not work but i read some users do.

In my case fastboot got stuck at sending boot.img forever until I removed the cable and then I got a similar or the same error. I solved this problem by disconnecting the cable, then typing in the command and pressing enter and after that putting in the cable again. Then it sent successfully and booted. I hope this helped someone.

If you have ryzen get a usb hub. If you have intel, run the command and wat for the "<wating for device>" and plug in the phone there. Also use usb 2.0

the other 2 i can get into fast boot, they were previously rooted & running orea/8 stock rooted
neither of those other 2 phones are recognized by my pc
i am using the adb reboot bootloader and get no joy on the 2 suborn phones.
both of the two phones refused to flash roms of any sort or type after a twrp wipe.
one of the phones is now fastboot only and nothing else ever happens and no connection to the pc is ever made
the other phone still goes into twrp most of the time,,sometimes fastboot only,,and still refuses to take any rom of any sort at all
my goal is to reflash twrp, and throw on lineage stable
BUT
not desktop connection?
someone pleas help me unbrick these two

updot
i found a way to get coms, but it is still failsauce.

thinking out loud.
everything i am seeing sais if my handset is not recognized by the desktop PC then my drivers are not correct.
problem with that statement is one of my 3 V20's does connect. correctly.
the other two are
FAILED (remote: unknown command)
as if there was no phone connected
but they are recognized under the fastboot devices, showing the connection is recognized by the PC, but not recognized by the phone.
how?
someone tell me pleas?
how do i get the 2 derpy phones to recognize the pc?

i am very much in a less then 3rd world country circumstance. (16 kbps max download speed for more then a week now) connecting to the internet is almost impossible as it is under excellent circumstances. for me to reboot into a Live os, and then set up a full NIC config before the Live freezes, glitches out or other wise kicks me in the face is almost impossible.
i am guna try to make an install. drag copy everything from the install to my os. this arch distro is built super similar to parrot os, so i might be able to make something work.
time will tell.
so far i have a failed atempt at this point

[email protected]:/home/lglaf$ cd lglaf
bash: cd: lglaf: No such file or directory
[email protected]:/home/lglaf$ sudo git checkout h918-miscwrte #for the TMO V20
error: pathspec 'h918-miscwrte' did not match any file(s) known to git
--------------------------------------------------------------------------------------------------------------------------------
the lafsploit is not able to "get" from the hub. looks like files have been removed?
now how do i get what i need?
took me an hour and a half to run less than 10 cmd lines.
not to mention thes fails are forcing me to unplug a phone while in download mode.
this is not fun.
any one know where i can download the file "h918-miscwrte"
looks like it is no longer on github
[email protected]:/home/lglaf# git pull
Already up to date.
[email protected]:/home/lglaf# git checkout h918-miscwrte

hard thing waiting.
