[MODEM] Main modem XX versions flashable through CWM

---

[SGS2] Modem Thread (modem guide) (thanks @geko95gek)
[REF] Modem+RIL CWM Installers (thanks @hawerpaul)

Hi everybody,
I did a lot of tests with different modem versions in order to see battery usage impact with my current configuration (Touch X v2 + ninphetamine 2.1.3).
To do those tests easilly and day after day with same situations, I used a CWM script (zip file) to avoid PC / Odin.

Here is those different modem versions with script :

For those who want to backup their modem before any flash, here is a CWM script I just made : HERE

Very quick user guide :
1/ download zip file and put it onto your internal sdcard
2/ if you have CWM app installed, you can use "Flash update" and select the zip file. Else reboot in CWM and use "install from zip".
No wipe needed

Alternate modem : NEKF2 HERE
Second alternate modem : NEKI2 (same network operator (THREE) released in Italy) HERE (thanks @thanksgiving60 and @s_wind)

Maybe someone more experienced than me could have a look into the modifications done by THREE to this modem and apply them on other versions...

Attached as a zip package flashable through CWM.

This is NOT the regular KF2 that you can find all over XDA, its extracted from my stock 3UK Rom, its modified by Three to serve their network better, and I can say they have done a good job.

Once again this is NOT the regular KF2 Modem

but thanks for the benchmarks.

Here is my results in terms of battery usage
(Fast Dormancy always enable, by the way my provider doesn't manage this mod)



Wake mode, GSM only (neither data, nor wifi, screen-off) :
KI4 (0.45%) < KG5 et KI3 (0.7%/h) < KG2 (0.8%/h) < KG6 et KI1 (0.9%/h) < KF2 (1%/h) < KH3 (1.25%/h) < KE4 (1.8%/h) < KE7 (1.9%/h) < KG1 (2.25%/h)

Wake mode, GSM + 3G activated (for mails), screen-off :
KI4 (0.7%) < KG5 et KI1 (1%/h) < KF2 et KG2 et KI3 (1.4%/h) < KG1 (1.7%/h) < KH3 (2%/h) < KG6 (2.3%/h) < KE7 (2.4%/h) < KE4 (3.4%/h)

2G usage (stream radio), screen-off :
KG5 (9%/h) < KG2 et KI4 (14%/h) < KG6 et KE4 (17%/h) < KG1 (18%/h) < KI1 (19%/h) < KF2 et KH3 (20%/h) < KE7 (22%/h)

3G usage (stream radio), screen-off :
KG6 (13%/h) < KG5 (14%/h) < KI3 et KI4 (15%/h) < KG2 et KI1 (16%/h) < KE4 et KF2 (18%/h)

Here is performance tests I did those last days (around 200) using versatile speedtest.net (so many possible issues) :

SpeedTest.net is a little bit complicated because we have a lot of infra between our GS2 and the server. So, we can have day after day, test after test, different results.
My approach is to bench a lot and provide a MIN/AVERAGE/MAX for each modem.
After that, my choice will be based on average battery usage.

All of this hard work is to provide a single view of what we can expect but, of course, because of so many networks, this is a little bit limited

I flashed the 2.3.5 KI3 and still get no Mobile Data ... I just came from villian to the 2.3.5 it was working on there just fine. Any ideas which one to flash?

Do you know the difference between Odin version and CWM version?

This is the same version. I just extracted modem.bin from each stock ROM and put it into a zip file with a small CWM script.

My idea is to give a way to avoid Odin/PC and to decorrelate ROM and modem versions.
Moreover, I am trying to investigate battery usage for each in some situations. I am not paying too much attention on network efficiency.

For the moment, the best one is KG5.
