Guest gwebb Posted March 7, 2011 Report Posted March 7, 2011 No, it's the problem with the Blade. I have a Pulse and a Blade. At the same time, same place and on the same network (T-Mobile, Hungary) my Pulse gets more than 1 Mbit/s (!) upload, while the Blade only gets 3G maximum 0,4 Mbit/s to the same server. Apparently this is a ROM problem. With the "256 MB" Blade ROM I had only simple 3G sign on my Blade toolbar, but after my Blade changed to 512 MB ROM version (newer version) I have my little "+" sign along with 3G. But it's indicate only HSDPA download. HSUPA not supported yet as I see. It's a real chinese phone. :( *bump* I realise this is an old topic but I'm seeing something similar to this. Using the same giffgaff SIM, and two phones at the same location -- LG GT540 and ZTE Blade, both based upon MSM7227 -- I'm seeing a big difference in Speedtest results. LG GT540 gets 3 Mb/s down and 1.5 Mb/s up, with a roughly 100 ms ping, hell it quite often goes faster than that touching 4 Mb/s. ZTE Blade gets 1.8 Mb/s down and 0.4 Mb/s up with a roughly 200 ms ping. Would ZTE take the same chipest and then deliberately knacker it so that the performance is so poor? I don't expect identical results but I thought it would be better than it is.
Guest sharix Posted March 7, 2011 Report Posted March 7, 2011 (edited) I'm in Slovenia and I get the H sign most of the time when using network data. I did a test with speedtest.net app right now three times: Down: 1975 kbps, 1270 kbps, 1604 kbps -> average 1616 kbps Up: 57 kbps, 63 kbps, 109 kbps -> average 76 kbps Edited March 7, 2011 by sharix

LG GT540 has a difference in build.prop relating to this issue, blade states gprs class 10, gt540 states gprs class 12, and there are references to 0 and 1 go grab a lg gt540 custom rom and you'll see what I mean Edited March 7, 2011 by hecatae
Guest wbaw Posted March 8, 2011 Report Posted March 8, 2011 LG GT540 has a difference in build.prop relating to this issue, blade states gprs class 10, gt540 states gprs class 12, and there are references to 0 and 1 go grab a lg gt540 custom rom and you'll see what I mean The gprs class should only affect 2g connections, class 12 has a 32-48k upload vs a 16-24k upload for class 10. ro.ril.hsxpa= might help, what does that say on a gt540 rom? it can be 1 2 or 3
Guest wbaw Posted March 8, 2011 Report Posted March 8, 2011 (edited) ro.ril.hsxpa=2 ro.ril.gprsclass=12 in build.prop seems to make no difference over the default values for me on CM7 (default is 1 & 10) ro.ril.hsxpa=3 ro.ril.gprsclass=32 are some different settings i've seen, they don't make any difference for me either. anybody else want to test it?

Guest hecatae Posted March 8, 2011 Report Posted March 8, 2011 might be the actual driver itself then
Guest wbaw Posted March 8, 2011 Report Posted March 8, 2011 might be the actual driver itself then There's a chance that my local cell tower doesn't support it, I'll speed test on another phone which should work. If anybody else wants to test those settings, they don't seem to hurt anything. I didn't test gprs, so there's a chance we could get faster gprs with that class 12 setting. I agree there's a good chance of it being the ril driver causing the problem too though.

Guest wbaw Posted March 8, 2011 Report Posted March 8, 2011 http://en.wikipedia.org/wiki/General_Packet_Radio_Service you can read about gprs classes there, highest is 34 Also from the cm forum post you linked 'There are many ro.ril parameters which I found from /system/lib/libhtc_ril.so:' I just looked through the blade's ril .so files with a hex editor, I can't see anything like those options, maybe it ignores everything in build.prop & has it's own hardcoded values.
Guest hecatae Posted March 8, 2011 Report Posted March 8, 2011 that's a shame if it does have hardcoded values.
Guest wbaw Posted March 8, 2011 Report Posted March 8, 2011 none of those options are in any of the zte roms & they don't appear to make any difference for me, so i think they might not exist in the ril driver that we use on the blade.
Guest hecatae Posted March 8, 2011 Report Posted March 8, 2011 would it involve finding what the gt540 ril uses and edit the blade ril?
Guest wbaw Posted March 8, 2011 Report Posted March 8, 2011 (edited) would it involve finding what the gt540 ril uses and edit the blade ril? the blade's ril files aren't open source, we only have the binaries, so it's hard to edit them. maybe the ril drivers from another phone with a similar chipset might work & might provide extra features. try searching google for libril-qc-1.so i think the LG GW620 has it & the t-mobile pulse, along with some sony & motorola phones. libril-qc-1.so from the orange uk b10 rom is 4k larger than the same file in cm7. maybe it's a later version? improved? added ... bad idea, it doesn't work in CM7, no idea why not. Looks like changing the ril driver isn't so simple. Edited March 8, 2011 by wbaw
Guest Coyote74 Posted March 9, 2011 Report Posted March 9, 2011 Blade should be HSUPA cause when connected by usb to PC, windows reports "HSUPA device"
Guest hecatae Posted March 9, 2011 Report Posted March 9, 2011 Blade should be HSUPA cause when connected by usb to PC, windows reports "HSUPA device" i agree, but the current ril driver does not enable HSUPA
