Hopefully its not hardware related.

First, can you verify you have a T999 model by looking under the battery?

The only thing I can think of for you to try is to Odin flash the stock firmware (not a rom).

Use the root66 version firmware to stay rooted.

If that doesnt help, it may be a hardware problem.
[T-Mobile, Samsung Galaxy SIII] superman63:
thanx doc. i was thinking of that but wasnt sure if i should flash the rooted version or original. will check it out and let you know he outcome. thnx again for the quick reply
[T-Mobile, Samsung Galaxy SIII] ndwgs:
I concur with the APN Settings.

No where near BMore, and only if I'm around Baltimore I get this kind of speeds. I live in College Park, and only Baltimore and Washington DC are the ones that got the LTE switch on. Confirmed by a coworker that has a Note 2 that when he's not in Washington...he gets 17Mbps/3Mbps respectively when on LTE he gets way higher (avg of 5 tests consecutively, a whooping 28Mbps/8Mbps).

Tested the LTE modem, and got same speeds as MD5. So I reverted back to MD5, and here are my results with APN changes posted by BassMan:

*note: I didn't get to record nor screen shot MD5 with no changes to my APN, which normally yields me 15-17Mbps/2.50Mbps respectively

Math-heads...

Calculate my average? Hihi :p

Edit:

This is a repost of my response from Doc's LTE FW

Hey guys I currently live in Paterson new jersey and I'm trying to find a better modem any suggestion?
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Look at the map. If anyone close by has posted their results that would make a good starting point.

If theres not then im sorry to say youre on your own, but I hope if you do some honest testing to find the best one you will add to the map!
[T-Mobile, Samsung Galaxy SIII] Dantenios:
Just wondering if there would be a Mobilicity VLDLL1 Modem as well :)
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
As soon as someone is willing to pull theirs and get it to me I can make it. I put out several requests but no one ever answered.

I can try to put one together from the firmware, and it should work.

Ill try to get to it sometime today.

what baseband are you running?

Thanks
[T-Mobile, Samsung Galaxy SIII] stncldtex:
I believe this is the code you are looking for. *#*#4636#*#*
[T-Mobile, Samsung Galaxy SIII] Perseus:
Thanks. I was asking Doc since this code was in his list, if he knew precisely what it did to the Modem.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Wow! I'm sorry I never got back to you on that! Trying to do too much at once I guess. If I ever go a week w/o answering like that feel free to remind me or pm me or something. Wasn't ignoring it on purpose. Ill look at it better tonight when I can get on my computer.

Sorry again.
[T-Mobile, Samsung Galaxy SIII] Perseus:
Hey Doc. No Worries. Next time I will remember to PM if needed. I know your RL is more demanding, so I prefer to go easy on you ! :laugh:
[T-Mobile, Samsung Galaxy SIII] IXChicharitoXI:
Is it possible to flash an ICS modem on a AOSP ROM? I'm running DLJA and I've been getting woeful results just like MD5.

I tired to search but nothing relevant comes up.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
I'm surprised you didn't find it. It's been asked several times in this thread as well as a few others.

Any modem, any Rom, any build.

Just be sure you flash one that is for your model phone.
[T-Mobile, Samsung Galaxy SIII] IXChicharitoXI:
Thanks, mate.

I figured it has been asked before but I couldn't get anything after re wording my search a few times.
[T-Mobile, Samsung Galaxy SIII] silhouette004:
I'm not 100% sure what I was running at the time, but I'm running T999UVDLJA right now (haven't flashed anything in awhile) and I've gotten better speeds than what I mentioned in that previous post.
[T-Mobile, Samsung Galaxy SIII] BJohnM:
Clarification on Models

OK, I apologize, and I saw it was asked previously, but I'm still not totally comfortable with the answer, and the last thing I want to do is brick the phone.

I have a T-MO T-999...not a T999V or T999(V). Can I install the UVDMD5 modem shown on the OP of this thread?
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Yes. MD5 is a T999 firmware so you are good to go.

And just so you know, flashing the T999V or T999L modems wouldn't brick your phone, they just wouldn't work. The partition layout is identical. This my not be the case with other models though.
[T-Mobile, Samsung Galaxy SIII] LuigiBull23:
So those modems wouldn't function and not that it's a big deal so long as you have an nv backup but could they potentially cause a loss of IMEI when reverting back to one of our own? or am I just going out of the whim here lol
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
If you flash the modem you wouldn't need to worry about the nv and imei backups as it doesn't touch anything but the modem. Just flash back to a working one.

No ones ever figured out the cause of imei loss. Flashing modems isn't any safer nor is it more likely to have it happen than flashing a rom. (To my knowledge though, no one's ever lost their imei after flashing a modem.)

This was a pretty widespread problem last year, then it seemed to subside. But now it's back to becoming widespread again.

Last year the best theory we could come up with was flashing with CWM seemed to be the culprit. It very rarely if ever happened with TWRP. CWM was the only common denominator we could find.

(@all This is just a theory so please don't argue the point just because you're loyal to a particular recovery) it may have nothing to do with it now anyway....

Just, if you haven't already make a backup of your nv items / imei!
[T-Mobile, Samsung Galaxy SIII] LuigiBull23:
I agree completely. I remember those issues occurring on CWM as well, though I was still in the beginning phase of learning Android.. For that and many other reasons I personally favor TWRP over CWM. It's never failed me. Even if I did prefer CWM you can't deny the fact that it was indeed the most common denominator. Besides, I'm always open to statements based on theory or opinion so no worries bro. Thank you for the clarification.
[T-Mobile, Samsung Galaxy SIII] Aerowinder:
This could be due to people using reboot nvbackup in the past when it was a widespread issue. Now it seems like most people have no idea what I'm talking about when I mention it. The IMEI loss problem became irrelevant, and so did the preventative measures. I think it's a reasonable assumption that the newcomers to the d2 are not immunizing themselves against potential loss. I've asked time and time again for someone who has run reboot nvbackup and still lost their IMEI to come forward. Crickets.

It was theorized, but there was never anything even resembling evidence that CWM was the cause. Mostly TWRP fanboys pointing fingers. I theorized that CWM was more widely used, thus the problem was more common with CWM, and a bunch of other stuff. Believe me when I say I want to like TWRP. What I would really like to try is 4ext.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
I wasn't aware of the reboot nvbackup back then. I thought it was discovered towards the end of last year.

I remember when the S3 first came out people immediately started losing imei's. It took Peoplearmy and Geek around a month to figure out how to back it up and longer to figure out how to inject it if lost without a backup.

They wouldn't have had to go through all of that if we had known about the reboot command. I think the reason no one knows about it now is because after we had our fix the problem subsided altogether and folks just didn't think about it anymore.

It's obvious new people aren't backing up just from seeing all the posts on it the past few weeks. But you have to consider that other than peoplearmys and Geeks threads (which got buried for a while), there's hardly any info on the subject here in our forum.

I honestly didn't know about the reboot nvbackup command until a couple of weeks ago myself. I never saw any mention of it here and only found it when I started helping people with it again.

Personally, I think it should be at the very top of every root method posted around here!

I have to disagree about the no evidence against cwm. When everyone was originally scrambling to find a fix, someone put up a public spreadsheet and asked anyone who lost their imei to fill it out. Literally the ONLY thing common between all entries was they used cwm to flash. Coupled with the various reports of the same around the S3 forums, it was the best, if not only lead we had. But no one who was actually working on it ever pointed fingers at cwm. Everyone knew there still wasn't enough data to say for sure. It was merely suggested that folks use TWRP for the time, just in case.

I do understand everyone wanting to defend CWM as it's always been a solid trustworthy recovery. But just because some people called it out based on data collected, they got hammered by others accusing them of being TWRP 'fanboys'. And the thing that irritated me the most, was no one ever actually accused cwm of being the definite cause, only that it was the best lead we had at the time. (Well, some took it that far, but it was usually a rumor mill type of thing). The point I'm trying to make is yes there was evidence that CWM might be the cause, but it still wasn't enough to say for certain.

Now, before anyone goes calling me a 'fanboy', yes I prefer TWRP, but I still like CWM too! I think they're both excellent recoveries, but I, like everyone, have my own preferences.

For others who may read this, we still have no.idea why this happens!
[T-Mobile, Samsung Galaxy SIII] Aerowinder:
This spreadsheet? https://docs.google.com/spreadsheet/ccc?key=0Arzp20hXNPi4dFg3UUozS2FQaERYNVJRVm1hWmJYQ3c#gid=0

Will have to agree to disagree that it's evidence. I'm pretty sure CWM was a lot more popular back then than TWRP, for this device.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
That's one. Forgot about that particular one tbh. There was a similar, yet simpler one for T-Mobile. But if you notice the color coding, the red/pink are the ones that lost imei. Every single red one was CWM. It was the same in the T-Mobile one I was referring to. (It was probably an earlier version as it was much simpler and didn't have near as many entries).

As I said though, it isn't enough to say definitively. That's why most people who paid attention would only suggest that it was a possibility and then suggest that if you are concerned about it, just to use TWRP for the time being.

Again, not nearly enough to close the case, but as stated earlier, it was the only thing that the loss reports had in common, which is why I do consider it evidence.

Don't worry, I'm not saying it even convinced me against CWM. But it certainly did raise an eyebrow!

[T-Mobile, Samsung Galaxy SIII] BTT8:
I hope I'm not alone when I say using data (hpsa+) makes my T999 VERY warm compared to wifi. Currently on MD5. Anyone with this observation?
[T-Mobile, Samsung Galaxy SIII] Aerowinder:
Pretty common issue with that baseband.
[T-Mobile, Samsung Galaxy SIII] CarlosBattousai:
Can I use

Baseband: UVMD5

From Build: UVDMD5

OS: JB 4.1.2

On my UVMD5 T99 when I'm on JB 4.2.2?
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Any modem, any build any Rom.

So if you have a T999, all of the modems for that model will work.
[T-Mobile, Samsung Galaxy SIII] CarlosBattousai:
Thanks for clearing that up for me man~
[T-Mobile, Samsung Galaxy SIII] Perseus:
Yes I too came to the same conclusion.

Doc do you think there might be another modem out soon or

that switching to prior modem is the only answer?

Please hit thanks if you find this useful.

[T-Mobile, Samsung Galaxy SIII] Woody:
Ok, I have been getting so-so to not so good "speeds" on any of these modems. I put Speed in quotes bc I think that my SpeedTest is giving me bad info.

I am in Cincinnati and the closet server it picks up is Wichita, Kansas. I go in to change servers and it says that Wichita is ony 47km from my position. Now even if you look at a tiny map, Kansas is way more than a thumb's length from Cincinnati (actually it is about 824miles).

I have uninstalled SpeedTest, cleared data, checked on Maps/GPS that I was in-fact in Cincinnati, deleted my GPS data and re-locked and toggled Airplane mode. Anyone have any more ideas?

I have decent data speeds (as far as feel goes) and not so decent "speeds" showing up on the app. I think that maybe something is connecting me to a far away tower (IRL and not just on the app) instead of one down the street so to say.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Hey man, couple things that may help you (and maybe others) out.

I dont personally think SpeedTest.net app is very reliable when it comes to real world use. (Much like any benchmark) this is why I ask everyone to use it for their tests, so at least we keep that part consistent.

I have tested with absolutely horrific speeds before then been able to turn around and DL a large file really quickly. Any speedtest result is impacted a lot by traffic and hosts, not just distance. My closest server is about 60 mi from me, but I usually get much faster speeds with a couple that are up to 200mi away.

I am planning to look into a few other testing methods when I get a chance, will update here when I have more on this.

In the meantime, sounds like you did one thing I may recommed everyone do, toggle airplane mode on/off just before testing. This insures you are on the best/closest tower. When you move around and connect to different towers, you may end up in an overlapping signal area, but stay connected to a tower further away. The airplane mode trick usually resolves this. When the phone reconnects it automatically picks the best available tower.

Another thing to try is see if one of your local cable providers has a speedtest feature. Try to use your browser to initiate a test either with a cable/telecom company or even www.speedtest.net and see if your speeds improve. Also when using the app try other locations as well. Im in N Alabama, but one of my best speedtest servers is in the Atlanta, GA area, but only sometimes!

Your issue with the app not knowing where you are is not uncommon. Many just dont notice it I think. Try turning on WiFi and then start the app (you may need to force stop in app or task mgr), seeing if it determines you location that way. If so choose your desired server then turn off WiFi. Last time that happened to me the WiFi trick seemed to fix it for quite some time. (Also make sure your location settings allow for Network based positioning and allow Location for Google search).

Try a different testing app like Cisco Gist, or FCC Speedtest (also by Ookla) as well. In the end it comes down to what works best in real world situations, but as long as you use the same testing methodology, your fastest test should still help you determine which modem will be best for regular use.

Doc, it seems you and I are on the same wavelength about a lot of things around here. Since I just came over to the GS3, I think that you and I will do some great things together. I don't mind helping people at all and I have 2 younger kids, so I have infinite patience (most times).

Thanks for ALL the info and I'll be lurking around the General and Q&A sections (I actually like it in there. Many don't, but I do).

Thanks again and I will report back later on with anything.

Mirror download stated about 19mb but I download it a couple of times and it's about 7mb which one is correct?
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Should be 19.42mb. Tried both my primary (minus) and mirror (dev-host) and they both work fine. Sounds like a bad download. Try again.
[T-Mobile, Samsung Galaxy SIII] KAsp3rd:
I'll check my mirror source. I have flashed most of them and they do work. Could be compression level and what not. As I stated they aren't mirrors of DOC's
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Yeah, they're not mine.

I appreciate the gesture of the mirror dude, but its probably best to keep other peoples work in their threads since they need to be the ones to support it and fix any problems.

Plus, the stuff ive worked on and am supporting already has 3 sources for people to get it from.

Dont get me wrong, i appreciate the offer and If you still want to mirror mine thats great, and you're welcome to do so. I just dont want to ask you to do any extra work you may not want to do and isn't urgently needed.

Thanks man!

Hey DocHoliday...

Notice that your user name is docholiday77 and 77 downloads to your latest LI7 modem... hehe. Thought I'd share I'm #77 :D :thumbup:
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Lol! Lucky Lucky!
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Finally got the minus crap worked around! Still dont know whats wrong with em!

Still like em though because they say theyll never delete/expire your files. One of my biggest peevs here is when you try to download something and its gone!

I think I mentioned earlier, but I really do try to get the modems pulled and released within a day. Figured it was a reasonable goal both for me to reach and for how long others may have to wait.
[T-Mobile, Samsung Galaxy SIII] Android_Monsters:
Really enjoying all the modem choices. Thanks a lot man
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
No problem! Im glad to get them for you guys!

And the list just keeps growing and growing! I wonder, what device has the record for the most fw releases, leaked or otherwise. Our GS3s gotta be close to breaking whatever that record may be!
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Maybe I missed it, but I'm not sure what post you were replying to. Switching to a prior modem is the only answer for what exactly? Unlocking?

As for a new modem...it'll just come out when we get our next firmware update. A total guess with nothing to back it up is a couple more months. No idea tbh.

Could be tomorrow! Could be Christmas! Hope its tomorrow. ...:D

Various Modems For Kc Mo Area

I've tested all of the JB modems, at home and at work. Tested each on speedtest.net app after a full reboot ran twice and took a screen shot of the best one. Then ran each for at least 12 hours in various real life tethering, http d/l's etc. Is it worth posting the pics?

Let me know..
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Definitely not all of them! :eek:

But feel free to post one for the best two modems if you want.

And you are welcome to share your results of course, just that many pics would be overkill.

And if you please, add your info to the map on page 1? Thanks! And kudos for actually doing all that testing! It is a helluva task with the number of modems available!:thumbup:
[T-Mobile, Samsung Galaxy SIII] njonas01:
So on my sii I used the note modem and it was awesome. Will it work with this phone?
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Probably not. No ones ever found a different devices modem that'd work on ours that I'm aware of. Some have bricked their phones by trying it btw. So I wouldn't recommend trying it. The gain would likely be minimal anyway.

Have you tried the ones we have available here? I'm sure at least one of them would be good.
