Hello. First of all I'd like to state that this is my first android device and I am still learning the whole process of rooting and flashing ROM's so bear with me.
So to my question. I installed BlackStar V1 yesterday and I noticed when performing a speed test that my 3G performance had dropped significantly. I have a 1Mbps download bandwith plan from the best provider in my area, and got full speed at 60-120ms with my previous phone and with stock and Omega V4 rom's with GS3 at all times of the day. However after installing BlackStar my latency tripled and download speed cut to third from the 1Mbps even at night when the network is less crowded. I can manage when I'm home or at work since the wifi works fine, but when on the move handling large e-mail attachments gets frustrating. Does anyone have an idea what might be the issue?
I haven't tried to restore my Omega nandroid backup yet in hopes this issue might get fixed somehow, but am forced in couple of days if it's not, which is a shame since i really like this rom .
Unfortunately I do not have screenshot of my speedtest result before installing BlackStar.
I have a little different speeds in helsinki with stock rooted ROM and fastest saunalahti multi-sim
Yeah that shows that the stock works fine, I actually realized to check the history tab and you can see that 3G has worked for me correctly in the past.
Could it be that the creator of the BlackStar has changed the stock modem with a different one that doesnt work well with finnish frequencies?

Seems like it was indeed a modem issue. Fixed after installing the new XXLF2 modem.

So I got my gs2 monday, as soon as I got home I rooted it and put cm9 on it. since then ive been trying lots of ics roms and leaks. it seems like on them all my data is terrible. Either incredibly slow speeds, or lots of drops where my data doesnt work. also im in america on tmobile, which means I only get 2g edge speeds, I know edge is slower but this is horrible.
anyone hve the same problem?
This problem is mentioned in almost every ICS thread, also with suggestions for fixes.
FYI, I am in the UK and my data is fine on CM9.

thanks.
im sure some of it has to do with me having tmobile so I can only get 2g speed. I love the phone but 2g is so bad.
I suggest to try diffrent modems

I suggest try a firmware that Samsung have actually released as opposed to a leaked beta buggy test rom .

I have had my Thunderbolt for over a year now and have been flashing numerous ROM's/radios since. I have always had great success in each one and as time has passed, newer and better ROM's having been coming out. I currently have the Full Blown Thunderstick ROM which I have found to be the best and smoothest ROM to date. There is only one probem.
I have noticed a drastic difference in the speeds while using this ROM/radio compared to all the ones used prior. I have flashed this ROM and it's respective radio on my Thunderbolt and numerous others and I still have the same issues with all. Can someone tell me why I went from 15mb down/7 mb up speeds which I had prior to now 3-4 mb down/.5-1mb up speeds with this MR4 setup? Also, why won't the ROM let me use the Wireless Tether for Root Users in addition to the Wi-Fi Hotspot one it came with? When I try to run and connect to it from any laptop, it says it's unable to connect the network address although I have no problem connecting to the Wi-Fi Hotspot one. But sometimes with the Wi-Fi Hotspot the ROM came with, it drops connectivity. It feels like it's not using the 4G LTE speeds but only the 3G speeds only.
Just curious, did you search first? The answer for wifi tether has been posted atleast 100 times. I posted it as recently as 2 days ago. As far as speeds, speedtest.net does not work properly with that rom, your info is not correct.

Oh I read the whole thread and I didnt really see anything that answered these questions. Im not going with speedtest.net. Im judging it based on certain websites and web-based programs which are now slower since I installed the ROM.
Did you try Barnacle? I haven't used the ROM you have, I run Liquid.
Most people claim that Wireless Tether works great with Liquid, but I couldn't get it to work. Once I used Barnacle, it not only worked, but I've been getting great speeds with it.
You need to run Imoseyon's kernel to fix the speed issue. It's been widely documented and discussed in almost every MR4 rom thread.
I'vd had the lean kernel flashed since the beginning and still no change in speeds

which IMO kernel are you using? I believe for mr4 you want v5.2.0. I have it if you cant find a link. pm me
i am using v6.1.0 which was documented to use
Hi Guys,
I recently got the SG2 on AT&T (i777) and the first day I had it stock I was getting consistent H+ connection in my house and pretty much everywhere I was going. I ran the speedtest app a couple times, and I was averaging 2.5-4 mbps downloading which wasn't too bad.
That same night I rooted the phone and flashed Phonebreaker 2.1 rom following the correct steps (Not my first time rooting/flashing roms, I've done it to my Tmobile SG2 a few times). However the following day it seems my data connection has become inconsistent and speeds have slowed down to a drag. The indicator on the phone can never stay on H+ or even H..it consistently cycles from H+ to 3G to H (tried it in same locations as the first day with the phone). I ran the speedtest a few times and my download speeds ranged from 300Kbps to 1.6mbps if I was lucky.
I tried looking around in all the forums, I re-did the APN settings found in these forums, I troubleshooted with AT&T but to no avail.
Anyone have any suggestions? Would much appreciate it as I love this ROM minus this data issue I'm having.
FYI - Stock only shows H+ even if your not actually on it.
Its an illusion AT&T does to make the user think they have great connection everywhere.
Also try flashing a different modem, that might be the issue with your speeds, cause I changed to the leak's modem upon many request.
Thanks LiLChris06!
I tried the KH7 modem which did nothing, and I tried the KK6 which seemed to improve it a bit. I went into AT&T today and they said maybe it's just a defective phone and were willing to switch it out, which I might do.
However I love this ROM so much, is it available without the custom modem you added or with a different modem in the install rather then the UCLK2 I think you included?
Thanks

Hmmmm...what you mean by is it available without the custom modem? Maybe Im reading it wrong. As you know, because you said you have tried different modems, there are many different modems you can try. Shouldn't matter what modem the ROM comes with. Think there is a modem thread around here that has some good info. I think Task also just uploaded the the new LC5 Modem
I should have worded my reply a little better, and it might come across as a newbie question but basically I was wondering if that rom came with the stock modem the i777 comes with because when I had the phone the first day stock, the data speeds were pretty reasonable (3-4 mbps/downloading).
Wasn't sure if flashing different modems other then the one that came with the phone originally would help out my issue, but I suppose it doesn't hurt to try. I did find the UCLC5 modem so I'll try that in a few minutes along with the other ones I haven't tried. If no luck, I'm going back to AT&T to exchange, probably defective phone like they said.
Thanks again for everyone's help
Sweet, found a solution!
I tried all 7 different modems under the same conditions, KJ1, KJ4 and KK6 were around the same ball park. KH7 and UCLC5 were a bit slower but close to each other, UCLC2 was by far the worst..and the winner was KJ2, big difference.
Thanks guys!

I noticed E2 is way faster. BUT big but, E2 has way worse reception.
Am i the only one?
I was on Jersey Shore today and I couldn't get any data working.
If that is the case for you, then you could flash a different modem I suppose.

I've noticed way faster data speeds on E2. I used to see about 2 down, now I see about 6 down. And I've had no signal issues, always 4 or 5 bars. Afaik, different modems can give vastly different performance for different people. All depends on your area and what not. Just experiment with the various modems. I'm just glad Samsung finally got one right for my area, as I've only ever seen about 3 down on any phone I've owned until now.

The AT&T version of both of those modems, which is all us Canadians have access to thus far, has, for me, had much worse data speed numbers (non LTE anyway) on the Telus network than the stock GB Telus modem.
The E2 modem is, in my very non scientific testing, slightly slower for us here in Canada. (again, HSPA only, no LTE coverage here yet)
I'd really be interested in understanding what is actually different between carrier modem implementations. I noticed a similar speed differential in the stock modems.
I tried adjusting the RF preferences but that doesn't solve it. Its almost like AT&T doesn't have the same implementation of HSPA+ as the Canadian carriers.
I say all that with some degree of confidence in the numbers... having installed a variety of ROMs n modems and the results from the stock Telus modem are consistently better when I can use it.
Currently on the One Beta and associated LE2 modem, it shows very wonky "bars" by times...like none, in what should be solid five bar area.
My fourth floor office which never wavered from five bars on stock.. Consistently now shows any where from 0 to 3... But it still transmits and receives calls and data.
A buddy of mine is testing the Telus 4.0 release with Premium Suite... so in any event, it shouldn't be too much longer.

is it really that much faster? ive yet to upgrade from UCLD3 because its just running fine, wanted the next time i update my phone to be the last (offical ICS since i doubt we will get a update any time soon after that)
I noticed a big difference in speed. UCLD3 used to stutter a lot and freeze up from time to time for no apparent reason. Haven't had any of those issues with UCLE2. Also, bugs that annoyed me in UCLD3 were fixed in UCLE2. I don't see any reason not to flash UCLE2.
I've been having a bug on ucle2 where I cant keep a wifi connection for in app downloads resulting in the download stopping I've tested on multiple ucle2 roms and confirmed no issue on ucld3 not sure how I got so special because I haven't seen anyone else report this that I know of

That actually happened to me. I reverted to D. Seems not as crazy fast but stable. With E I got 1mB (that's bytes) per second. D tops at about 600.

my wifi performs completely fine until I try to do an in app download such as gta3, modern combat 3, order and chaos etc etc.. couldn't figure out why I'm the only one, did full wipes clean installs tried flapps and apps ucle2 roms, even when I went to CM9 which uses the ucle2 kernel I had the problem.. so frustrating lol then go back to ucld3 and problem never shows up once
So last night I updated my s3 to the latest UK firmware, XXBLG8, And I can't tell if my problems stem from the latest update!
After the update many apps wouldn't open and I'd have to do a battery pull to sort out each individual app that refused to load, everything's fine now, however, my data connectivity seems to have worsened considerably, even with full signal strength and HSPDA nothing will load, the browser shows errors that I'm not connected to the internet and apps such as the Play Store and Speedtest won't connect.
Anyone else experiencing this problem? Would I be able to flash back to an earlier firmware using ODIN? (I'm new to the s3 scene, just jumped ship from a Desire HD and haven't yet fully got my bearings.)
Thanks guys!

only problem i have noticed is that speedtest does no longer work but everything else perfect. Infact my hsdpa connection is much better on this rom. you can easily downgrade your rom back if you wish just follow this excellent guide to flash via odin.

Hmm, I suppose it could be the area I'm in, but it's usually fine where I am. I'll give it another couple of days and test it in other areas to see if the problem persists.
I've upgraded via ODIN before, just wasn't sure if there were restrictions on downgrading etc, I'll give the thread you linked to a good read now, thanks!
Try changing Modem BULF1 for starters .
I find the last two updates modems are very poor .

I am also on the 8 firmware and so far it's good.
looks like speedtest.net have changed there site slightly if you goto site with mobile agent set on browser it redirects to the play store to the speedtest app, change browser to desktop as long as you have flash installed all is fine. I believe this has been done site to the up and coming removal of mobile flash

Thanks, I'll give it a go!
So I decided to bust out my Desire HD, I remembered I still have a month left on my old contract before it gets terminated, checked the data connectivity on there and I seem to be having the same issues. Looks like it's a problem with 3 in general rather than it being my s3. Which is good news for my s3!
Must have been pure coincidence that I started having these issues right after upgrading, however, I tried a few new modems and have been getting better signal (no change with the data issues) so at least I've taken something away from the experience
Isn't there an issue with 3 UK branded ROMs experiencing network issues when you flash the unbranded ROM? I think you may need to flash a separate modem, Google it, I may be wrong.
I'm on 3uk running blg8 not had any problems making, receiving calls and texts and my network is fine on both wireless and 3g

It seems to be working pretty well this morning on both my s3 and DHD, and Frostfree I'll have to check that out, I've already flashed a few new modems and I'm getting better performance so that might very well be the case!
I'm in Folkestone (south east coast)
I am on BLG6 with Cyanogen Mod 10 latest rom and so far I have great speeds (4-5Mb) on speed test app.
Will try flashing BLG8 when i can find a download link. I just want the modem to flash not a whole rom cos i am loving JB on the SGS3.
