Can't update

So my dad went out and bought a nakasig/tilapia it's running Android 4.2.1 and bootloader is 4.13. Having just updated my razor/flo via fastboot everything was setup and working. "adb reboot bootloader" reboots the nakasig/tilapia into fastboot mode and "fastboot devices" shows the nakasig/tilapia serial number. Every other fastboot command just hangs there and does nothing. "fastboot oem unlock" does not prompt me to unlock bootloader. "fastboot reboot" doesn't even reboot the tablet. I use Linux so I figured I would try Windows following the thread sticky'd in this forum http://forum.xda-developers.com/showthread.php?t=2175086 same problem adb works fastboot will list the device but can't do anything with it. "fastboot getvar all" did give me an error however "FAILED (command write failed (Unknown error))" all the other commands just hang there doing nothing saying nothing. Having tried Windows and Linux setups which I have used on my other Nexus devices without issue I am starting to think its an issue with the bootloader maybe I need some older version of fastboot.
Is there a way to flash bootloader from inside Android or Recovery? I can use Towelroot to root the tablet then flash TWRP from Android and boot into TWRP but I don't think you can flash a bootloader from there or unlock the bootloader can you?
Edit: according to http://forum.xda-developers.com/showthread.php?t=2068207 the nakasig/tilapia bootloader is encrypted so you can't flash or unlock it without fastboot.

OK so you have a 2013 N7 that does not have this problem, but your dad's 2012 does. Two different pieces of hardware.
Could it be a driver issue? Sometimes when the drivers are not talking to it correctly you get these flaky results. Different USB cable/port?
Theoretically there is a flash all command you can use to flash an update of the whole thing including the bootloader without it being unlocked. However if you are getting write errors then you should really be cautious because that could just fry it instead of fixing it.

ADB and fasboot use the same drivers don't they? While in Anroid adb works fine I can adb shell I can adb push/get I can adb reboot.

Tried every cable and port I have. Different computers even.

NONE of the fastboot commands work except "fastboot devices"

No, AFAIK they're different drivers, and different devices often require a distinct driver install too.

Got any sources on that info?

WOW
weird! really weird!
I really don't know what the issue, the fact that it happens on Linux and on Windows makes me think to an hardware realted issue, unfortunately..
As long as I know adb and fastboot do not use exactly the same drivers, but you download and install them together, so it should n not be a problem, this one..
The only think I can suggest you atm is to try with Linux by logging in as superuser (su). On my slackware with my "normal" user adb works as usual, but if I try to use fastboot the terminal says me No permissions..
I hope someway your distro has the same issue, even if your fastboot devices success!
So login as superuser and try to use fastboot. If you do not install it in /bin partition you should have to locate its directory and then use
./fastboot devices
or any other command but with ./fastboot instead of fastboot..
hope it helps.. I really hope!!

For that matter, on a whim... when you open a command prompt in Windows to adb to your device, try running Command Prompt as an Administrator. Sometimes Windows is weird like that.

Please keep questions in the Q&A section. Development sections are for development only.
Thread moved to Q&A.

It's probably a problem with drivers. It's common in Windows. Search in the forum for these keywords: ADB Windows driver problems
I resolved using a Linux distro (Debian Sid, but Ubuntu is OK and more friendly too), no problems with drivers anymore.

but when i type adb device i found my device but when
he enter to the fastboot mode it said waiting for device
do you can help me please how do you have fixed it

Do you run the command prompt as Administrator (right clic on the Command Prompt icon > Run as Administrator)?
Do you run fastboot devices before to check if the phone is recognized by fastboot?

i have run the cmd as an admiristratore but how to reconized it

with the command:
Code:
fastboot devices
if the phone is recognized, it should respond with
Code:
random123 fastboot
if nothing happens, you have to check your adb drivers (uninstall and reinstall for example).

Problems Unlocking bootloader

Hi guys,
I'm having problems unlocking bootloader.
The phone enter into fastboot mode but when I type "fastboot oem unlock-go" in the cmd of windows it doesn't recognize my device.
I have installed Minimal ADB and Fastboot and I have installed ADB Driver installer too but it doesn't recognize the device.
Can anybody help me with this please?
I need to unlock it because I want to root it.
Thanks

Have you tried unplugging and replugging when the phone goes into fastboot mode?
I just got my pro 3, did the OTA to the .19 software and unlocked and rooted just today and my girlfriend's very very fresh windows 10 install.
If that doesn't work just delete the adb driver, replug the device and windows should install the same drivers I used.

LG Leon H340N fastboot not working

Hello!
I have a very big problem. My LG Leon H340N is "bricked" totally, there is only fastboot mode in phone, nothing else.
The problem is that fastboot is not working, when i try to execute some commands it all the time gives me answer: FAILED(Unknow Command) and i don't know how to fix this, i don't have access to download mode, i don't have access to hard reset menu, i don't have access to recovery mode, only fastboot
Could somebody help me ?

How did you get into fastboot mode?

I connect device and laptop via USB and device is starting into fastboot mode automatically.
When device is connected i open cmd (run as administrator) and C:\ cd adb = C:\adb> fastboot devices - and it shows me my device connected as fastboot device then I try to execute some commands but it always gives FAILED(UnknowCommand). The fastboot drivers are installed - original google drivers from android sdk. I'm using Windows 7 Home Premium, i try execute some commands on other laptop with windows 7 starter but the same thing - FAILED(Unknow Command).
Thank you for reply, Regards

I have still allways the same Problem with rooing from my P8 lite.
I got today a new update with EMUI 4.03.
After the update I got the message that my phone is rooted and it is dangerous.
Root checker basic shows the message "Sorry! Root access is not proberly installrd on this device"
SuperSU shows the message "Root undetected"
How can I root my P8 Lite correct? who can help me?
many thanks.

Sorry for asking:
1.Does your USB cable/port work good?
What does fastboot devices command says are your devices listed?
2.Does your bootloader truly unlocked?(i running ALE-L21C432B614 and bootloader writes unlocked even if locked i think its a bug)
What is the current output of fastboot oem unlock <your bootloader unlock code>?

I think the USB-Port and cable is ok.
1.) Is start my P8 lite with comand "adb.exe reboot bootloader" in fastboot&rescue mode.
The P8 lite screen shows:
"fastboot&rescue mode
Please connect Usb Cable to your Computer and Open Hisuite
More Information:
http://zh.ui.vmall.com/emotiondownload.php?mod=restore
reboot_enter_fastboot_common_func
green Android Picture
Phone Unlocked
Keep Pressing Volume Up to Exit this Mode"
2.) I will download the twrp with command "fastboot flash recovery twrp.img"
twrp.img is "RecoveryTwrpV3.0.2.img".
3.) after start the fastboot command shows the prompt the following messages
"C:\fastboot flash recovery twrp.img
< waiting for device >"
and nothing happens anymore.
The UniversalAdbDriverSetup.msi Drivers are installed on my PC.
My current Phone Build: ALE-L21C432B614
EMUI: 4.0.3
Android 6.0
I have no a solution for my problem for root my phone.

Go to fastboot mod and after you see the fastboot&Rescue mod screen run this command in your pc:
fastboot devices
If fastboot detects your phone you should see your serial number.
If not you probably will see nothing in the command line on your PC.
Give me the output please

can you please tell me how can i get build number using adb bootl loader
