ASOP, AKOP, CM10 and wimax - Samsung Epic 4G Touch

I would like to have to have just a normal Jelly Bean 4.1 or know 4.2.1 experience of my phone. I tried out the Pacman rom and CM10 rom. Both have the same issue. My 4g wimax speeds go from 10megs to 750kbps.
Is there something that I missing or is everyone just fine with horrible speeds? I even tried the temp boot and updated my PRL and such.
Is there anyone running a stock android 4.1 or 4.2.1 with 10 meg wimax speeds? or does this not exists.
currently im running TW jelly bean FL16 rom....perfect wimax. so its not JB.
~also which I found annoying was this was the same issue on my piece of crap evo3d. wimax would go from 10megs down to 750kbps on every ASOP, AKOP, CM9 and up.

Some have said that its because there is no kernel source for JB. So aosp roms don't have kernel source for the kernels they use.

So when the developer of the roms say 4g is working, its actually not?

No. It is working.
Tbh I never fully trust speedtest.net servers. For example.. I have 2 servers in columbus, oh and 1 in radnor,oh near me. Columbus servers are 50 miles closer to me than radnor ones. Still I always get 2-3 times faster results on radnor servers.
So in reality I have a faster throughput but I am misled by server caps. Now i know this is not the case because obviously on a tw rom you get much faster results.
What I am trying to say here is that when I am on 4g on non tw roms, 4g is much faster than 3g even though speedtests tells another story for me. 4g and 3g speedtests give me similar results. I also get faster tranafer rates when downloading files when on 4g.
So my guess always has been that on non tw jb roms, speedtests are not measured correctly.

i live in downtown Cincinnati with perfect 4g signal. Speedtest is one way to check. Another is by trying to download things.it took a couple mins to download speedtest. I mean its like being on 56k modem or something. So no 4g is not working correctly. it might be working, but at 1/12 of the speed its suppose to.

The source for aosp kernel was made from ics kernel source which apparently has a buggy 4g problem... That's why custom kernels also have throttled 4g. Hopefully after jb source drops somebody will make another kernel with the new source...

It's an issue with source built kernels. Nobody really knows why it happens hut it is what it is. Repacked kernels are where it is if you want 4g speeds to not be absymal.

What roms come with repacked kernels? Does that mean just modded touchwiz based roms?

Slower data on CM9/AOKP roms.. no HSPA+ 42 perhaps?

I noticed on all CM9/AOKP based roms on the T989, my 4G data isn't as fast. By comparison on stock and Darkside roms, My speed tests are consistently double-digit download (10-14 kbps) and around 3kbps upload. But on CM9/AOKP based roms, I don't get above 5 kbps down, and 2 kbps up. These are the typical speeds I would be getting on an HSPA+ 21 phone.
Do we have any information on why this is? Do CM9/AOKP not support HSPA+ 42? Is there a script I can run to improve this?
Thank you in advance.
I noticed the the same thing. On tw ics I normally get 8-18mbps. Aokp and cm9 5-8mbps but good enough
Sent from my SAMSUNG-SGH-T989 using xda premium
I have had sporadic success getting 13 mbps by flashing the le1 radio included with darkside. For the most part though i cant use cm9/aokp for this reason, no one really knows why to my understanding.
I flashed one of the Tellus radios and it's working very well for me. Running AOKP

I agree-I have the same issue. I'm on CM9 and love it but it's vever been as fast as the Dark Side roms.
lol but noooooooo everyone looooves CM roms because they don't have bugs, issues or anything
Try flashing one of the modems for the Darkside ROMs when you flash an AOKP or CM based rom?
That should do the trick. Probably is just a modem issue over anything else.

No it's not a modem issue. I've already tried all the Darkside modems and the issue is the same and consistent. I truly believe whatever makes HSPA+ 42 work on stock and darkside is not implemented on the CM9/AOKP roms, because the speeds I get are consistent with what people with Nexus phones in my area on T-Mobile get, and they only use HSPA+ 21.
I've gotten a best of 18.50Mbps down on AOKP.

Yea no joy with that, reg build without any radios fetches me 8 Mbps max in an area that i get 13 Mbps.
Yes, I noticed a slow down from GB to stock (debloated & rooted) ICS ROMs... But it seems like AOKP may be even a little slower than that.
I've seen some users post lines that you can replace in the build.prop file which they said gave them faster speeds on AOKP... but then people just stopped talking about them.
The user did say that the only way he could see a difference in speeds using the build.prop fix was to tether his phone to another device and do the speedtest on it... For some reason he was certain that speedtest.net was reporting lower numbers for AOKP ROMs, but the speed was still there... You'll have to go back and read the AOKP thread in the general section to find it.

I don't know about that I flashed UVLE1 radio from darkside and actually got speed test results of about 12 Mbps to 13 for a few hours. After about a half day of use it dropped back down to 8. Reflashed the radio and it still wouldn't go back up.

I've tried several speed tests, not just speedtest.net and I get the same consistent results of slower data speeds. As far as real-world results, I have seen problems streaming video on PLEX on 4G with CM9/AOKP roms that work just fine with Darkside. So it's not just an issue with speedtest. Something is different. Would love to have some input on this from Eugene or Yaldak or someone like that.

[Q] LTE on all AOSP ROMS

One reason that's kept me from flashing an AOSP rom and keeping it is the latest strength issue. I live in the middle of no where basically but some how I have lte which averages 10+mbps on two but drops to under 2mbps on every aspect romantic I've tried. I there a reason for this and any fixes available?
Sent from my SPH-L710 using xda app-developers app
I'm curious to see what others say about this. Others have said that AOSP ROMs simply display your true signal strength and that's why people think they have weaker signal but you are actually experiencing much weaker signal.
Just for more clarification, if you use an AOSP rom and have weak signal, can you just flash a tw rom and instantly have normal signal?

AOSP roms display your true voice/evdo signal, that's different from LTE/data.
The reason users tend to get less mobile data performance on AOSP is because, essentially, AOSP is ported to our device and to any device that is not a Nexus. That's why we have issues, because people like CM and preludedrew (evervolv) have to work with the files provided to us by the OEM, files which are not compiled for AOSP, but for whatever proprietary UI came with the phone (Sense, Touchwiz, Motoblur, LG UI, etc etc).
However, now with the leak from the S4 Google Edition, we should see all around improvements to the US SGS3 CM10.1 and other 4 2.2 AOSP roms.

Wow you guys work hella fast I might even flash some nightlies now
Edit: If one wanted to could they simply place these files in any AOSP rom they wanted or would it be best to just wait for the dev to do so?
Sent from my SPH-L710 using xda app-developers app
Having more bars on tw is apparently normal. Something about the way it displays the signal is different than the way AOSP roms do it. I don't know all the technical aspects of it. IIRC the bars aren't an indication of how strong your data is though. I've been in places where I had "full bars" but no data at all.
Have you tried liquidsmooth? It's my daily and haven't had problems with LTE. My house is out in a hilly area and don't get LTE there but I do at my friends house and the speed hasn't been any slower there as far as I can tell. 22mb down usually there.
Edit: CNex to the rescue lol

All thanks go to SamMobile for providing that leak lol.
Someone in the CM thread commented that after flashing the nightly with the S4GE blobs, their 3G went from around 500kbps to 1500kbps...but of course ymmv (your mileage may vary).

[Q] Same carrier, two different phones, difference reception

I have my Galaxy S3 and my coworker has an HTC Evo. Both of us have Sprint and yet his phone gets 3 bars of reception whereas mine only gets 1, 2 if I'm very, very lucky.
AFAIK, he's running stock, unrooted and I'm running rooted with latest LiquidSmooth 2.9 with the MD4 modem. No idea what modem he has.
What could be the reason why he's getting better reception? Better antenna build in the Evo?

Some of it has to do with the rom. Some aosp roms show a more accurate bar reading...which is why your's is fewer. I wouldn't really get to worked up over it. They both probably get similar reception and data speeds on 3g

I would suggest Updating PRL / Profile. Maybe even trying a different Modem. Not everyone gets great reception on MD4. You may have to experiment to see which works better for you.
If you want to properly know if your device is getting less of a signal you need to flash a TW rom, preferably one which is close to stock update prl and profile. Then check your signal and data speeds compared to your friends. AOSP roms remember are built from leaks, and ported from other devices. There is no true aosp source for the Sprint S3. So there's lots of patches and coding which goes into getting the cdma radios working.

We've actually done a Speedtest together and his had a higher data rate than mine. I've had different modem with the earlier builds of Liquid Smooth as well, but still low reception. I've also updated my PRL/Profile in the past in hopes that it'll help but sadly no.
I'll look into having a TouchWiz ROM versus this one. I just love how LiquidSmooth is, so hoping I can find a TW ROM that's just as fun.
EDIT: I don't even know how to find a TouchWiz ROM. I figured it would say "TW" along the subject line, the same way AOSP does, but alas I cannot find that. I have heard of Goodness, is that a TW ROM?

Most likely cause all the roms which do not say AOSP or CM or AOKP or something like that are TW roms. I would recommend MOAR or TPR The People's Rom.

OP,
Unless you're being very careful with your comparisons and using quantitative, and not qualitative, data like db, seeing more "signal bars" means nothing.
Sent from my buttered S3
You must also keep in mind, that even after you switch to a TW Rom. There is no guarantee that you will see better reception. IE more bars. There are quite a few variables involved. What you should concentrate on is making your device the best it can be for you. As CNexus stated. When comparing you have to compare Apples to Apples, and Oranges to Oranges.

[Q] Custom kernel that DOESN'T bork 4g speeds?

Does anyone know of a custom non-TW ROM that doesn't bork the wimax speeds on this phone? Pretty much any rom I've tried means that my 4g speeds cap at about 600kbps. Then I can flash right back to a TW rom and get ~9mbps. My understanding is that there's something with the kernel that limits that, but does anyone know of a workaround or a non-TW rom that doesn't have it?
I ask because (1) I use my mobile connection as my home internet connection since I'm poor and (2) I hate, hate, hate, hate touchwiz. IMHO, it's the ugliest UI I do believe I've ever seen and I'd love to use a CM rom but haven't found anything that doesn't screw up the wimax speeds. Any ideas?
Thanks.

Sweet, thanks! Any non-TW rom I've tried means I'm NEVER able to get above 600k, so I'll give this one a shot. Thanks again
I think it's a kernel issue rather than the ROM (although many ROMs bundle the kernel with them), source-based kernels seem to cause low 4G speeds for me (slower than 3G), while stock/repacked ones work fine. I've played with all 4 kernels on the Lightweight ROM, for example, and only stock and Agat's repacked gave me good 4G speeds.

Just try different ones... make sure they are ICS modem's though or you won't have data.
Remember... just because we all have the same device... doesn't mean that they run the same. So what works best for you might not work best for another..

I've heard this before, and it doesn't make much sense. Yes, location matters, but two of the same phone in the same location will likely produce negligible differences in reception when using the same modem.

You sound upset... that wasn't my intention buddy. But I can tell you that I have had two epic's and my first one hated JB modem's and my current one gets great signal on JB modem's... and yes it's the same area and no new towers.
Maybe it was the difference in ICS and JB, I'm not sure.
But fl24 is the newest ICS modem and that's what I get the best signal with when I'm running any cm/aosp/aokp based roms... and I've tried quite a few different modems. That was in the Chicago area and Springfield area... both in Illinois.
Also... this current epic runs aokp roms great.. where my first one wouldn't... all chips are not created equal or maybe I just didn't now what I was doing then...
Hope somebody in youre area jumps in with some info for you. Good luck..

No, not upset. My apologies if I came off that way. I work with radios on embedded devices and my experience has been that they all perform within <1% difference of each other when running the same software. Now, it's quite possible to have bad chips, but then all sorts of things go wrong and no amount of software can adequately compensate.
My guess is that ICS vs JB did make the difference for you. And as for AOKP roms running better, maybe it was a different version of the ROM?
Thanks for the input about FL24. I'll try it out.
I have two Epic 4G Touchs in my possession
One of them I can't even get data working on Any AOSP ROMS even though I was using ICS and GB modems.
I now use it as a media device so it doesn't really matter.
My daily driver is the complete opposite.
I get the best reception using FC14 modem.
Unless someone lives in your area with the same phone, they can tell you which modem works best for said area.
