[Q] Can't get into Fastboot

Ok, now we know that fastboot and adb can be troublesome on WIndows, but despite lots of reading, I;m a bit stumped as to what if anything is wrong with my WIN 7 setup.

ADB works fine, I can get into adb from a cmd window, enter commands and get the expected result.

"adb devices" returns the 16 digit serial number, a few spaces and "device"
"adb reboot" reboots as normal

I cannot get into fastboot from adb though. (I can use a factory cable to enter fastboot, no problem, and using the Quick Boot app, I can get into Fastboot no probs.

Once there,
"fastboot -i 0x1949 getvar product" returns -> product: Tate-PVT-08
"fastboot -i 0x1949 devices" returns -> 13EE000200000001 fastboot
"fastboot -i 0x1949 reboot" gets me out into normal mode.

All above leads me (correctly or not) to think that the drivers, system etc are ok and I'm doing something wrong.
eg
" adb reboot-bootloader" (as written in adb help) simply reboots the device as usual
as does
"adb reboot bootloader"
"adb reboot boot loader"

I've seen the various syntax here and elsewhere

It seems as if the command is read as far as "reboot" and everything after that is ignored. So, what am I doing wrong?

You're doing nothing wrong. I believe that command does not work in the later os versions.

Oh bum. You know, I thought maybe the drivers were wrong, or my syntax wrong, but I never thought the OS would be wrong!! Lol

Does anyone know when this change was introduced and which was the last OS release that could be booted into fastboot via adb?

Thanks Red. The shell command works, but issuing a command that waits for a handshake then rebooting doesn't. I also tried the same command whilst the device was powered down, but in both cases it just booted normally.

Of course my factory cable also works, and I am rooted

thanks safinwasi. I managed ok without needing this option, It was more for reassurance. For the benefit of anyone who might need to do this, I have seen that command without quotes, so try both.

I think you should get a fastboot cable less hassle!

Hmmm, I think you should read posts properly before making comments.

I've had my factory cable since I rooted my first Kindle about 15 months ago.
