Thumbs up
great!
thx txr33. good chance to test several modems for me.

maybe a short overview could be useful. just to see which modem offers best connectivity in which countries.

I tested all modems for about two and a half hour and did some measurement.

I'm living in Germany, Baden Württemberg and for me the two ...ALK2 work best.

XXALK2 has a slightly better reception, but AEALK2 is better at WLAN conncectivity (faster) and finding internet connection at poor reception.

Interestingly the original firmware (T-Mobile) is the worst from all the listed ones, by far!
The internet speed in all networks (3G, H+...) is half (!) as fast compared to the ...ALK2 ones

I attached the exel chart I did for the test. It's German, but I hope you'll get what it means, otherwise I'll translate it.

Hi all,

This may help a few French users, and maybe others too. I quickly made a CWM flashable zip by using one of the files available on this thread (many thanks to all the devs for the great job by the way !) and replacing the modem inside by the one contained in the French SFR I9305XXALK5 ROM file (jellybean 4.1.1).

I noticed that this modem is giving me by far the best data connexion when used along with custom ROMs. As some German users mentionned earlier, I noticed that when I use custom ROMs (Ripper or Supreme) I can not benefit from Dual Carrier (or 4G) anymore. My data connexion is then restricted to 3G or HSPDA.

By flashing this file, I managed to at least connect in HSPDA+. But still no dual carrier, unfortunately . As I am a very basic user, I can not investigate the reason why I lose 4G when I flash a custom ROM (4G works nicely when I use SFR provider stock ROM).

If you want to give it a try, the file is available HERE.

I would be glad to read if some people are experiencing the same problems.

ok, flashing your GT-I9305 modems on a GT-I9305N was a bad idea, it broke my 4G and more or mess my 3G too
I only had "E" (Edge?) on AEALK2 and I had 0.05Mbit
with XXALK2 I messured ~2Mbit and I had 3G and H+ for a short while.

I found a source of my original firmware and extracted the modem and made it to a flashable cwm zip
(first time I did this and I did it the easy way, editing an existing .zip downloaded from first post, so my .zip will have the "Ripper" message while flashing)

tested ok by me.

Hi

That's a pity, sorry for this problem. The modem I took from the French provider SFR is I9305AEALK2. I just discussed with a member on a French forum, and he thinks that this version is optimized for SFR network. But the fact that your phone is a "N" version can also explain the differences. I do not know what is the difference between N and non-N versions.

I think I will try your modem, in order to see if I can get a better connexion. With my file I get something like 10 Mbps on speedtest when connected on HSPDA+.

Ok.

I tried your modem and it worked on my phone (I9305), although the connexion was a bit slower than with my file (but I did not make many tests), around 5Mbps.

But a strange thing occured when I tried to reflash my own file : the flashing went right but when I rebooted I had lost Data + GSM connexions. I had to reflash my stock ROM in order to get them back (reflashing another modem did not fix anything). Strange.
