The (most?) text strings are stored in usr/local/Kobo/nickel. This file contains among other things several zlib-compressed blocks. Nine of these blocks contain the text strings of the supported languages.

Thank you for the reply
Maybe you know the address in the nickel?

The starting addresses in FW 3.13.1 are as follows. For language identification I add one example string for each language. (I chose it randomly.)

The language string is in 2 byte annotation, e.g. space = \x00\x20. It is followed by the reference string in English in simple ASCII (EDIT: utf8).

If you need help with finding and uncompressing zlib streams, there is a python script by PeterT somewhere in this forum (maybe you can find it). You cannot use the script as it is, but it might get you started.

Edit: Here is the link to the post containing the python script. For a general description see here.

This addresses for Kobo Glo?

Thanks a lot.

This first approx of python code

Spoiler:

#!/usr/bin/python2

__author__ = 'axa'

import zlib

ZLIB_MARKERS = ['\x78\x9c']
filename = 'nickel-glo'

infile = open(filename, 'r')
data = infile.read()
end = len(data)

pos = 0
found = False

while pos < end:
    window = data[pos:pos+2]
    for marker in ZLIB_MARKERS:
        if window == marker:
            start = pos
            rest_of_data = data[start:]
            decomp_obj = zlib.decompressobj()
            uncompressed_msg = decomp_obj.decompress(rest_of_data)
            print "===== Message start %0x\n%s" % (pos, uncompressed_msg)

    pos += 1

There is a bug, but the result is very interesting.

The firmware is almost identical between the different devices. The differences are some of the fonts and images.

[AxaRu]

Yes, thanks

Since I do not speak python, I cannot help you with the code. Just for information: You are decompressing successfully the first 4 of 19 zlib streams. Streams 11 to 19 contain the language strings.

AxaRu,

I do not understand anything (I am not computer programmer), but I'm very interested in how to translate the interface. I want my aura H2O in catalan

I will be grateful if reports its progress and if you get it, help to me.

thanks

Simply change strings from one language to another, then zipping block an replace in nickel.

You could send me the text strings and then zipping block an replace in nickel my translate?

or explain step by step how to do it in a very, very clear and simple way?

[AxaRu]

Sure, but I'm still just at the beginning

Ok. Thanks

Second approach

Spoiler:

#!/usr/bin/python2
# -- coding: utf-8 --

__author__ = 'axa'

import zlib

ZLIB_MARKERS = ['\x78\x9c']

def zipstreams(filename) :
    with open(filename, 'rb') as fh:
        data = fh.read()

    pos = 0

    while pos < len(data) :
        window = data[pos:pos+2]
        for marker in ZLIB_MARKERS:
            if window == marker:
                try:
                    zo = zlib.decompress(data[pos:])
                    if zo[0:4] not in ['\x89PNG', '\x8aMNG']:
                        print '{:x} : {:s}'.format(pos, repr(zo)[0:1000])
                except zlib.error:
                    pos = pos
        pos += 1
        if pos == len(data):
            break

zipstreams('nickel-glo')
