joker97: The xxls8 that came with 4.1.2 gives me superior reception to dolp4 but haven't tested speed. I'm I using a t model phone


Yeah... I was hoping that XXLS8 would be good... but no go for me... I could only get EDGE! Undecided Surprised Sealed

But the reception here is a bit dicey (Goodwood Heights/Manuaku)... my personal belief is that it is the proximity to the airport approach path and things like Primary Radar and Navaids interfering with signal... coz when I go into the city (or anywhere else really) I get much better reception...

I might try flashing XXLS8 this afternoon and see if it works in the city when I go to see my GF... perhaps it just isn't as forgiving in low signal area's as DOLP4?? Tongue Out

Don't know in the swimming pool on dolp4 no reception. On xxls8 had decent speed. But haven't flashed back to check. Cox if it ain't broke ...

I'm on xt. Sounds like you're not. If you're on 2d try xxki4 or xxlps

Are you actually using it on telecom?

joker97: T makes no difference


It makes a huge difference if you want high speed mobile data...

I have tested this.. A LOT... And If you don't use a T specific modem (aka baseband)... Chances are you won't be able to get 3G connection... I did some extensive research, and found that apparently the T has some extra hardware on the antenna to tweak it for better performance on the Telecom/Telstra 3G network bands (850MHz from memory)... I cant find the source for that at present...

BUT I have tried the ever popular BVLP7,the latest XXLS8 (from official international 4.1.2 releases) and a few others from this collection... The only ones that give reliable 3G service are the i9100T specific ones... And then, I have found the one from the last official telecom release DOLP4 to be the best)

Having said that, modems seem to be fussy... And the best for one user/network may not be the best for another...

FWIW, I am on 2degrees... With an i9100T... In Auckland...


Yeah this is just not true. I had a i9100T and used various modems with it. While the T modems gave a slightly stronger signal the non-T modems worked perfectly fine and in some cases I could get on average higher data speeds.

The i9100T doesn't have different hardware at all. This has been disproved quite a few times by people on XDA and other places. I owned a i9100 and i900T and tore them both down to check myself. Simply it is a different model because it is tuned to comply with Australian regulatory requirements and prefer 850MHz over other frequencies.

Some conjecture: http://webdevsys.com/gt-i9100t.htm
Some evidence: http://forums.whirlpool.net.au/forum-replies.cfm?t=1926314&#r5

i9100T hardware - http://img440.imageshack.us/img440/2918/dsc00589sz.jpg
i9100 hardware - http://guide-images.ifixit.net/igi/bOCjli3mGykCADXT.large

Note that the i9100 doesn't have that chip...  Apparently this is some sort of filter... a quick google of RAFTP98 comes up with this datasheet

I'll experiment some more... but in my experience, without a T modem, I don't get reliable 3G :(



EDIT: As a disclaimer, I should point out that I am running on an AOSP based ROM (SlimBean), which is currently utilising the CM Kernel for the i9100 version...

As opposed to Wanam/Neat/Alliance etc which are based on Stock... So this might also have an impact on the RIL etc...

I am now in the unfortunate position of having a nasty little shatter over my S2's menu button. It's still quite usable with a screen protector to protect from the jagged glass but while I can't get it fixed for at least a couple of weeks there is now way it can stay like this for very long.

Has anyone purchased replacement screen/digitiser assemblies? I'm looking at different options on Ebay or Amazon as most NZ places are a good deal pricier. Are there chinese knock-offs of the OEM parts or are all the parts around actually OEM? I'd hate to get one only to discover it's got a crappy screen or something like that.

Help!

Lee

a big oops coming up

the reception seemed to be ok ... but i tell you what - just tested the speed at work. T modem 7+Mbps upload just under 1Mbps. the XXLS8 = 500kbps / 300kbps 

this has been repeated.

so now i'm back on DOLP4 ... if it aint broke you can still fix it!

now i need to go back to the swimming pool (not sure when) and find out why i can never get reception on any other modems apart from the XXLS8 ...

IMO, speedtest.net is generally accepted as the defacto standard...

They have an app on the play store...

I've just started testing i9100T JJLS2 modem that I got from here

Is a modem+RIL from an official 4.1.2 i9100T release (Pelephone in Israel)... the only i9100T JB release available on sammobile.com... seems to be working OK on my build of 4.2.2... as in, I get H and H+ connections... not convinced it is as good as DOLP4... but I'll give it a good couple of days before I make a final decision Wink

Also try an app called "Network Signal Info"... gives you a good overview of what your mobile signal is actually doing... reception strength, network type (ie. EDGE, GPRS, HSDPA etc)...

That way you'll get a better idea of what network connection you are getting... and what the reception is like...

Its free... you just need to put up with the ads ;)
