Mercado, I noticed your from my neck of the woods. What modem did you find to be the fastest? Reason I ask is because I was steadily getting on average 30-35mbps when Lte was 1st introduced and now on Avg 10mbps. I'm on the latest now and not sure what I was using before. Thanks
[Sprint Samsung Galaxy S III] .Nox:
I found the same thing. At first LTE speeds were insane...upwards of 45mb/sec.

Sprint has since capped us. Bastards.

Can I damage my radio flashing roms? I went from a touch wiz to an MIUI rom did full wipes prior to flashing the new roms. When I went to the MIUI rom something happened which ended up making the phone not boot properly and ended up flashing back to stock, rerouting, then reflashing the MIUI rom. Now, on TW the data and phone really is slow with what seems to be a hard time finding signal. On MIUI the data is smoking fast but phone is having a tough time finding signal and also ends up dropping a ton of calls. I've updated PRL and Profile on both TW and MIUI as well as different modems with no back to none qualityimprovement returning at least the phone quality to normal. Definitely appreciate any help/suggestions.

Had same issue with miui v5 4

[Sprint Samsung Galaxy S III] jake0125:
What did you do to "fix" the issue? No matter what rom or modem I run, my phone is not what is used to be and the data is so much better on MIUI/AOSP.

Lol they may be updating the tower in ur area I live in Michigan and happends to me all the time....sometimes I have blazing internet and sometime its not worth a crap at the same location more than likely its the issue

Yeah I have to flop back and forth between MC3 and MD4 depending on the week, here in the Phoenix/Mesa/Gilbert area... And I know they are messing with the towers because I have seen guys on them for awhile now.... Moving between them.... Screwing with us end users

What should I do if I flashed the LF9 modem and now my reception bars are gray?
[Sprint Samsung Galaxy S III] POWerSUrgeSW3:
Gray means that Google has not linked with itself. Do you have data access? Do they change from gray when you connect to WiFi? I would check under SYSTEM SETTINGS--> ACCOUNTS to see if everything is syncing....

If you're up to it try flashing a different modem like MD4. See if anything changes. Otherwise you might have to go through the process of updating your PRL and Profiles.

Maybe a dumb question - even though my build and baseband are MD4, why does it say MC3 under "Android System" in the application manager? Probably doesn't mean anything but I was just curious.
[Sprint Samsung Galaxy S III] POWerSUrgeSW3:
What ROM are you running? MC3 was a leaked version for the D2SPR, but never put into production. Then MD4 came out as stable.and most ROM makers builtnoff that. Some who build off every release, including leaked, might have updated some code to MD4 but ones that didn't Nees changing left as MC3. I've seen a couple ROM makers do that..

The People's ROM.
[Sprint Samsung Galaxy S III] styles420:
The People's Rom will never be built on any leak, it's one of the lead developer's rules in order to maintain TPR's reputation as one of the most stable roms around.

That value could have been changed by a mod, although if you installed a mod for one version on top of a rom that is based on a different version, that could cause problems - some may be obvious, but others may be difficult to notice and frustrating to find...
[Sprint Samsung Galaxy S III] bso44:
Interesting...I've never heard of that before and I've never flashed an MC3 based ROM on this phone. What kind of mod would change that value?

Just to show you guys that I'm not BSing, here are the screenshots:
[Sprint Samsung Galaxy S III] styles420:
The value wouldn't be changed, it would be the entire file that was replaced...

But in this case, we determined that android system is actually framework-res.apk, which I'm told did not change between the MC3 leak and MD4. I double checked my own (relatively unaltered) TPR install, and I show the same version, and I believe I recall a report from someone who checked a fresh, clean install and saw the same version as well :)

Anyone seen updated download links/md5s for the LF9 radio? The two links on the first post don't match, and one has a different file name.
[Sprint Samsung Galaxy S III] kngdmond:
Glad I'm not the only one with messed up service. Bought a brand new Sprint SG3 (2 weeks old) and out of the box it had horrible data and cellular connections in Phoenix.

Unbelievably slow, 1 or 2 bars max and no 4g. Been searching for a fix. Ditching stock ROM helped. Hope one of theses files will do the trick.
[Sprint Samsung Galaxy S III] POWerSUrgeSW3:
Oh and it depends on where you are at in Phoenix too... Because Sprint is upgrading towers for LTE... Service in areas are up and down due to number of towers they are working on at one time...

I've seen LTE service by Country Club and Baseline personally...

I'm in the Lichfield Park area. I've had good connections with Wicked Sensations. Hit 4g several times. But I've recently switched to LiquidSmooth. I really like the ROM but I can't say I like the connectivity that it and CM 10 deliver.

Sprint working on the towers explains some of the dead spots and drops.
[Sprint Samsung Galaxy S III] POWerSUrgeSW3:
Yeah I found the same... Switched back to Wicked and have stayed.

Good luck with service... I pretty much use WiFi everywhere in town for anything important. Fingers crossed we'll get better service after the upgrade!

Has anyone seen MD7 modem for Boost SG3??

Awesome thread!!! Great info and people, thank you. I have been trying to find it, yes I searched, but can only find the whole stock rom, either rooted,. Tar, etc but can't find just the modem. Any help I would be greatly appreciative and extremely happy!!!

Thanks again to all!!!
[Sprint Samsung Galaxy S III] POWerSUrgeSW3:
Well stock modem for which version of the stock ROM? typically when an OTA comes out he modem is updated. So for the current version available for a Sprint SGSIII the modem would be the MD4. Which is linked in the OP.

Hey guys...so an old friend of mine is has a Sprint GS3 and he rooted the phone herself when she first got it....while looking through her phone setting (trying to help her with something else) I noticed that she hasn't updated her phone since baseband "LI3". Now I've read the post..and I know that freeza is excellent at providing official updates. Here's where my problem comes in.

When I try to flash the baseband/radio flashabel update via CWM...it keep failing...I've tried several different files and got the same results. When I had a S3 (for sprint) I had an issue like that but I don't remember what I did to fix it. I believe I had to do something through ODin but I honestly don't remember. Can anyone provide any answers? Thanks

PS- I'm not trying to flash a rom for her..I just want to get her updated to the MD4...

Be careful...now that 4.3 is rolling out you will not be able to re-root your device. Have you tried downloading a stock, rooted ROM? You should probably do the upgrade to MD4 that way and not risk being unable to root your friend's device.

You might have to completely unroot the device back to the factory. It might have done something to the partition that the radio resides in.

I need help with the freaking radio on this sprint gs3. I was able to Odin to stock ROM. All works except the freaking signal.......
[Sprint Samsung Galaxy S III] bilgerryan:
Do an activation reset... ##72786# in the dialer. It would also help to know which stock ROM you're talking about... But the first thing should fix your problem.
[Sprint Samsung Galaxy S III] dmonleo:
No luck... Think I fried it when flashing it to pp+...going to open it up and check wire connections....

More likely scenario: you made an error flashing the phone to page plus.

I can accept that, any suggestions on how to rectify this FUBAR?

I've never flashed to another carrier, I would suggest asking in the thread most closely related to flashing to Page Plus and they can give you some ideas.

[Sprint Samsung Galaxy S III] copota:
I have a question.

I recently purchased a Samsung Galaxy S III SPH-L710 for use with FreedomPop. In the process of tweaking, I figured I'd try out some other modems.

After installation of three different modems from the first page links, I get the Baseband Unknown error.

I've tried flashing modems while on a Stock Samsung build of KK 4.4.2.

I tried PRL Updates (no connection reported). Tried an activation reset ##72786# (goes to a page that lists SCRTN, and nothing happens).

My stock modem shows as: Baseband version: L710VPUDND8

Do I already have a decent modem with the stock build, or are these other modems even compatible with my phone?

Thanks for any help.
[Sprint Samsung Galaxy S III] bilgerryan:
That is the only modem you can use besides NDC. KitKat won't let your downgrade the modem. So yep, that's as good as you're gonna get.

I'm new to the Samsung way of doing things, so I have a question.

When I flash a new radio (I guess they're modems in Samsungland), should I be on a stock ROM and update my PRL and profile afterwards?

On my Evo 4G, it was recommended to do that, but I haven't seen it mentioned here. I guess updating your profile and PRL would be a good idea regardless, which would require a stock ROM. Just thought I'd see how everyone else was up/downgrading their modems.
[Sprint Samsung Galaxy S III] Naddict:
Short answer to your question is yes, but you can update PRL and profile on a good, non-stock rom....
[Sprint Samsung Galaxy S III] EndlessDissent:
Well, by stock, I meant anything based on the stock TW ROM. Thank you. I'll be sure to flash back to stock before upgrading my modem.

Night and day difference with LF9 vs LG2. Haven't tried LEN yet to compare speeds. Thanks! LG2 was a nightmare here in Houston. I was lucky to get 100kbps downloads with it and it rarely connected to 4g.
[Sprint Samsung Galaxy S III] jarnow94:
You don't have to be on a stock-based ROM to flash radios with this method, I just did it on CM10 and it worked perfectly.
[Sprint Samsung Galaxy S III] EndlessDissent:
On my Evo, I got into the habit of updating my PRL and profile when I would flash a new radio. It still sounds like a good idea. I think it's worth the extra 10 minutes to flash a stock ROM and update that stuff.
[Sprint Samsung Galaxy S III] Naddict:
Yuuup... Can't hurt...
[Sprint Samsung Galaxy S III] Krazy_Calvin:
I installed lf9 onto the blazer 1.5 rom and the difference is mind boggling. The service was unusable for data in my house with the newest radio. In my house it would always say data roaming and 1x for the signal. The lowest number of bars on 3g if I was lucky. The local sprint guy told me 2013 for 4G in my area so there was never a possibility for that.

[Sprint Samsung Galaxy S III] treedog5:
Not sure if i got a bad download or what, but when i check my baseband it reads (unknown). now i have no data and can't get my hands on a cable to hook my phone to the computer..AAAHHHHH

I had downloaded the LF9 modem and the back up zip and applied both to internal sd.. not sure what went wrong..
[Sprint Samsung Galaxy S III] mercado79:
sorry to hear it. i've added md5 values to the OP, that way you can check to see if you got a bad download.

yeah, i checked the MD5 and it's completely different from the one you posted for the LF9 modem. but the back up zip MD5 numbers are the same. so i must have gotten a bad download some how. but i will download from computer when i get home and hopefully that fixes it.. thanks for the MD5

[Sprint Samsung Galaxy S III] freeza:
Anyone having the baseband unknown errors with no service should check the following:

/system/etc/firmware/ I'm assuming there are a lot of files then when it should only be these:

wcd9310

a225_pfp.fw

a225_pm4.fw

a225p5_pm4.fw

a300_pfp.fw

a300_pm4.fw

leia_pfp_470.fw

leia_pm4_470.fw

vidc_1080p.fw

cyttsp_8960_cdp.hex

After removing all but those and rebooting, your service and baseband should return to normal.
[Sprint Samsung Galaxy S III] techusky:
I ran several trials to test the connection speeds of the LG2/LEN/LF9 radios and also the difference of setting the network mode to CDMA vs. LTE/CDMA (I'm in an area without LTE coverage). I used the SpeedTest.net app on the latest CM10 build for these tests. Between each set of tests, I rebooted the phone, and made sure no other programs were running in the background. My phone was plugged into power the entire time, and I made sure it was in the exact same place on my table the entire time. I am outside of the Cincinnati, OH area.

Summary (in order of download speeds):

1. LF9 (CDMA Mode) - 987.1 Kbps

2. LF9 (LTE/CDMA Mode) - 541.1 Kbps

3. LEN (CDMA Mode) - 452.5 Kbps

4. LG2 (LTE/CDMA Mode) - 333.3 Kbps

5. LG2 (CDMA Mode) - 314.4 Kbps

6. LEN (LTE/CDMA Mode) - 211.1 Kbps

Summary (in order of upload speeds):

1. LF9 (CDMA Mode) - 693.6 Kbps

2. LEN (LTE/CDMA Mode) - 643.2 Kbps

3. LEN (CDMA Mode) - 373.8 Kbps

4. LG2 (CDMA Mode) - 225.5 Kbps

5. LF9 (LTE/CDMA Mode) - 176 Kbps

6. LG2 (LTE/CDMA Mode) - 174.8 Kbps

See my spreadsheet on Google Docs for the full results.

Same here. Most of my extra files are in the format of "modem.bXX" (modem.b01, modem.b02, etc.) or "modem_fX.bXX" (modem_fw.b01, modem_f1.b10, etc.). I'm guessing they're backup or database files of some sort. They should be safe to delete, but if you're not having problems, I see no reason to risk it.

Also, what network mode are you using? CDMA or LTE/CDMA? Assuming you're in a non-LTE coverage area, try changing your mode to just CDMA if it isn't already there and then re-test your speeds. I found that CDMA-only mode for me was consistently faster.

I have the exact same situation going on. My upload speeds are consistently faster than my download speeds. I get between 80 and 120kbps download and above 200 upload. I am also in an area where there is no LTE and most likely we are at the end of their upgrade schedule. I am sticking with LF9 because I actually get data connectivity in my house where with LG2 I get maybe one bar if I am lucky and it keeps saying data roaming.
