whenever I boot-up ESP or restart it (the button on it),
he enters this loop and it stays in it for way too long
Isn't there a watchdog to stop it? or some interrupt or whatever..

It is because he was trying to connect to my WiFi every time it was booting up.
When I managed to:
import network
network.WLAN().disconnect() (I did it with the ESPlorer, this would be impossible with putty)
while the pause between rebooting, which lasts about 300ms, it finally stabilized
Please fix this somehow, change the boot routine or smth

So connecting to the wifi was causing the fault and then rebooting? Then that's a bug that should be fixed (boot routine would stay the same). Please try again with the latest code to see if it is fixed or not.

The same thing happened, but this time it showed (after a few reboots) :

and it stopped, actually freezed. When I restarted it, it finally connected to the WiFi. And I doubt that it is because my signal is week. The net modem for wifi is 1 meter from me so I have extremely strong signal

Now this thing pops out a few times when I turn the power on, and it just crashes. It takes me about 30 mins just to boot it up and enter the REPL mode
Maybe it is just me doing something that shouldn't be done, even though I don't know what would that be.
I use the pyboard's 3v3 as power source and CH340 as usb-ttl, everyhting on win10.
But the firmware thing is done on Linux
I hope this can be at least a little helpful to fix the bugs :D

Try something else. ESP8266 requires peaks of 500mA and pyboard's LDO can supply only 300mA.

With a 9v battery and LM7805, together with pyb's 3v3, it boots as it should :)
Thank you, Sir, for the advice
I never expected it to "eat" that much power
