Speed tests with radios
I've done some speed tests with the different modems.
All modems (except 1), are from stympy's modem zip (look elsewhere in this forum).
All tests performed on the Telstra Australia network, in Melbourne, using the Ookla Speedtest tool.
SIM1 : Telstra SIM card
SIM2 : foreign SIM in roaming mode
Only SIM1 speeds were tested.
P780 Chinese model 4Gb, production date 15/03/14
Stock
P780_ROW_S124_140403 ROM version flashed.
Ran speed test 3 times, took average of 3 runs
Modems flashed in recovery, with Wipe of Dalvik Cache + Cache.
In case of a none working SIM2, restarted phone to double check.
All names are name of zip in the package without the .zip extension.
Remarks :
- Either fast speed but SIM2 not working
- Either slow speed (seemed to be capped at 30kB/s) and SIM2 always working
- For fast speeds, the SIM1 always directly became active as 3G/H+
- For slow speeds, the SIM1 connected as G first, then switched to 3G mode after 20 seconds
- V51,V52 (all zips with this version number in it) suffered from capped speed
- also noticed that the order of flashing the modems seemed to create some issues. I noticed that modem.S920.for.P780 showed the capped behavior too after flashing it after V18 Modem_S920_CN_V18. However, trying other combinations again, I could not reproduce the issue. And only this particular modem showed the issue.
- V17_modem.S920.for.P780.zip and modem.S920.for.P780.zip are identical.
Result :
Fastest (working SIM2 + good speed SIM1) combinations were:
-
modem.S920.for.P780, mddb BPLGUInfoCustomAppSrcP_MT6589_S00_P780_V15 : got results between 800 and 1600 kB/s DL, but running the test about 5 times, it is usually more around 800-900 kB/s
-
V18 Modem_S920_CN_V18, mddb BPLGUInfoCustomAppSrcP_MT6589_S00_S920_V18 : got results up to 1700 kB/s DL, but running the test about 5 times, it is usually around 1200 kB/s
In my previous post on this thread I was also concerned about the unstable signal. Both modems mentioned above as the fastest working, also showed a more stable signal strength.
See the results in the attached PDF.
Hope this is useful
