Amazfit 2: cannot get to fastboot - Amazfit

Hi guys,
I was following tutorial in order to install stock international FW on my Amazfit 2. However something has failed at step 11, when I was trying to "adb shell reboot bootloader". I got
- exec '/system/bin/sh' failed: Not a directory (20) -
using port=5555

Watches are now stuck at amazfit logo and I cannot seem to get to fastboot. Does anybody knows, how to get to fastboot via some key combo on Amazfit 2? I could find just Amazfit solution (this "4 seconds" hint), however it does not seem to work for Amazfit 2...
Any help appreciated, thanks!

Try just this instead:
Code:
adb reboot bootloader
or
Code:
adb reboot-bootloader

Hi thanks for the help,
However I got this idea as well before (based on my general android devices experience) however what it does is that it just reboots normally leading to splash screen stuck. It does not matter whether I issue adb reboot bootloader, adb reboot-bootloader or adb reboot lalala. I think it just grasps adb reboot part only and does normal reboot. However, thank you!.

Well, if your watch gets into a bootloop after you use reboot, then something else is wrong... Normal reboot works, just "reboot bootloader" fails?

---

No, unfortunatelly both normal reboot and reboot bootloader lead to bootloop with Amazfit logo :/

---

Fastboot finds your device? Can you wipe both data and cache?

Only adb devices sees it. But as I cannot get to bootloader, fastboot does not see it, so I cannot do anything...

Have you ever tried to flash another ROM? It seems that system is broken, that's why you get bootloops and cannot get to bootloader. You have to find a way to do it manually, most devices has some combination at start up to activate recovery and/or fastboot...
Make sure fastboot drivers are installed:

Then check this for manually activate fastboot:

Hi Ifom, thanks again for your energy and willingness to help me.
I would like to flash another ROM, however right for that I would need to get to bootloader. Guide in second link does not work, probably it is intended just for Amazfit 1. This is actually my original question, whether there is something like this for Amazfit 2, because I cannot find it anywhere.

Be aware that the method is really hard to get right, it's unlikely you'll get it immediately. It took me maybe 10 minutes of testing to get it to work

---

You were right! I can confirm now that this method work also for Amazfit 2, however it is kind of tricky. Took me 20 mins to do it right.
Thank you both for helping me out, I appreciate your friendliness very much!

Take the "Huami_AMAZFIT_Tool_1.0.1.1" and click on "reboot bootloader". This works!

That requires ADB, which requires the watch to at least get to that stage, which isn't the case if you break the kernel

I cannot enter Fastboot Mode.

I have an Amazfit and I can't get into Fastboot Mode at all. I have tried all of the alternatives described here many, many times. One question: can Windows / USB port influence not being able to enter Fastboot? Should I try on a Windows 7 for example?
