Need to update version ? How ?

[elpa]

I downloaded AT command set doc (reported version is 0.25), testing many command I get "ERROR".
AT+GMR returns 00160901, so I think i need to update the firmware.
I'm running on Linux (kubuntu 13), after reading in the forum I downloaded AT_bin_v0.25_1024+KB_flash_can_upgrade.zip and flash_download_tool_python2.6-2.7_wxpython3.0_release_v2.0_SOURCE.rar
I installed python2.7 python-wxgtk2.8 python-wxtools
After reading README.txt, I ran "python frame_test.py". I got:

Traceback (most recent call last):
File "frame_test.py", line 140, in <module>
TestFrame().Show()
File "frame_test.py", line 128, in __init__
self.fm1 = TestFrame_uint( pos=(20,20),prnt=self)
File "frame_test.py", line 41, in __init__
self.panel_path=pp.Panel2(self)
TypeError: __init__() takes exactly 3 arguments (2 given)

Am I doing some mistakes ? Did I download the correct files ? Which is the correct procedure to update the firmware ?
Please include all the instruction in a doc file, I lost 1 day in finding a way to make it work (and it doesn't work, yet). I never used python, and I don't want to learn it. For example, if you simply write that to start that program you must type "python frame_test.py", I would save 1 hour of work.
Thank you

Hi,

You could use FLASH_DOWNLOAD_TOOLS_v1.2_150512.rar here http://bbs.espressif.com/viewtopic.php?f=5&t=433

Unzip it and use "flash_download_tool_v1.2_150512.exe" to download bin files into flash directly.

Using AT_v0.25 please make sure your flash size is 1024KB or larger than that.

download:
boot_v1.4.bin 0x00000
user1.1024.new.2.bin 0x01000
blank.bin 0x7e000 & 0xfe000

Thanks for your interest in ESP8266 !
