What is the best CDMA radio flash file for stock ICS

I am currently using LC1. Seems to improve my wifi reception quite a bit. But cdma and 3g signal still sucks. So just a quick poll for everyone. Which radio to use on ICS, and dl links if you have them. Thanks!!!

Really which is best is very subjective. I have personally never seen a difference with any of them. Theoretically though, the latest one should be the best one. Here is the link to the thread in the development section.

Thanks for the reply. I have seen that thread and tried all except the KD8, I didn't notice a difference with any but LC1. My signal seemed the same but my speed tests were faster at home with the airave. Which I know runs the same 3g speed constantly. . . According to my other phones. The point of the post really was to see if anyone knew of a better radio. In their opinion besides the ones on that list. But I will update after I try the KD8.

No noticeable difference between the two.

Wifi speeds are not necessarily dependent on the used baseband firmware. Wifi speeds are influenced in fact much more by the used drivers (corresponding shared objects with "so" extension and library files) and its bugs. These drivers are located on the system partition. Official binary blobs containing wifi drivers can be downloaded. The official ROM uses binary blobs (proprietary SW) for wifi operation. Though some custom ROMs may contain open source drivers.

There aren't different radios than those. If you see a different radio not in that list, you should probably not flash it if they're claiming it's for our phone. Obviously a new radio could come out again and there could technically be some radio that never went official but if those make it into the public, the thread would likely be updated and have them.

[Q] Extremely bad internet speeds after rooting

Hello, so basically I have rooted my Speedy from 2.3.4 by using the bootloader unlock method posted by VICODAN in his tutorial but now I find that I am having insanely slow download/upload speeds compared to before rooting.
I have flashed the latest radio after finding THIS thread and I also tried the method from HERE to try and at least boost my speeds. I have also updated my profile and PRL through my Sense rom but nothing seems to help.
If anyone could give me any advice I would greatly appreciated it. I am on MikShifted-G v2.1 running dodgekernal v1.6. Thanks in advance.
I would also like to know if there is any way that I can go back to the stock 2.3.4 GB.

Welcome to sprint, the not now, maybe later network... :beer:

Well I've found that your speeds depend on what time of day it is. I know that's BS, but it's what I've found. Posted some Screen Shots Below of my Speeds.

The only time I get decent speeds from sprint is at night. Like 2am night.

You could also try the 3G Turbo Charger. You'll find it on THIS thread. Just make sure to read before installing.

Maybe you had roaming enabled in your old/stock rom and it's turned off be default in your new rom?

Well the thing is that I had perfectly fine speeds in my area prior to rooting.
I downloaded the "Network signal speeds booster" and "Fresh netowork booster", both from the play store and I am having almost back to normal speeds now, there was a dramatic increase in speed after I used both of those.
But I have also looked at the 3G Turbo Charger thread that prboy linked and I will definitely be trying that as well

I Just noticed this (several months later), but prboy, for your top screenshot you're connected to 4G, and in the bottom you're using 3G? I think in yours specifically it was only the connection you were using and not actually the time of day...

Well I've actually redone the Tests recently. Certain times of the day in my area must have some Heavy Network Traffic. Because the Network does slow down at the same times daily. But only during the week . Strangely enough I just noticed that I posted the wrong Screenshot . Although I do have to admit I'm not exactly a Scientist .

Haha yeah, but thats good to know, and yes, kinda weird that you would get faster speed on weekends you would think that it would be the other way around.
But anyway, thanks for sharing your results, I've done some tests recently too and they seem to be following a similar pattern...so even though you may not be a scientist, there is some truth to what you said
Sent from my PG06100

Yeah it's really bad from like 5 to 8 PM... You wanna see good 3G speeds, get on there at 3 or 4 AM, crazy good speeds cuz nobody's using the network... Except people like me who set stuff to download before they go to bed LOL

My 3g is really bad and it does not matter what time of day. 4g does not exist here, I am going to try 3g supercharger this weekend and see if I can make some progress.

I've had good results with the 3G TurboCharger. It just took a few tries before I found the correct setting. Downloading the App Speedtest.net will help you dial it in.

Tried 3g supercharger without any sucess. Perhaps someday the signal will get better.

You can change the PRL without QSPT if your on a Sense Rom. Check out THIS Guide. Just be warned using certain PRL's can get you into issues with Sprint because of constant Roaming. Also you may want to do a search for the latest PRL's, as the ones linked in the post seem to be bit old.

Data drops

Okay, so my phone had been connecting to data and then just dropping within a minute and try to reconnect and so on, so I sent it into Samsung. It turns out, all they did was take the update that Samsung had put out while they had my phone and said it was fixed. It may have seemed fixed to them, but it is definitely not. It seems as though it only happens when I'm in a 3G only area which is where I live so I basically cannot use my data at all. I know it works when I leave where I live because I went to Los Angeles last month and my 4G and my 3G were working fine. I just don't understand it. I know it's not because my area has bad 3G coverage cause it's fine. I'm just so flustered. Any help?

Looks like tower problem to me since it works fine in town.
Flash every modem available to see if you can find one that works with your 3G tower. Have seen older radios that worked better with 3G due to the towers being old tech. Since the phone and radios are new may not be able to find radio that works consistently. The 4G will work with with any 4G tower. If not able to get 3G contact Verizon and put in a ticket on your local tower. Hope this makes sense.

All radios are on Rootzwiki. If radios don't work call them back. Nothing wrong with phone if works in town although also depends how far you are from tower. If any Verizon phone works you have a case for upgrade of tower or phone. If just at home may give you extender. Do not let them charge you for it.

This device is solid on 4g and when in a 3g only area...soon as you get to a area where the data switches between 4g/3g/1x it becomes flaky at best no doubt. Beans rom seems to have the most stable data connection whem Im on the outskirts of a solid 4g signal...it is a device issue that should be fixed with a software update at some point. The problem is its easier for verizon to release a device with bugs, then to spend the extra time and cash to R&D and fix them before release date. I know it does not make sense, but think about it from there end. Lets say VZW has a device thats 90% bug free, so they release it to start locking people in on new contracts and rake in the money hoping folks dont complain about minor issues. If folks do comlain, well then vzw will run you thru the mill and send you a refurb, or open a claim ticket...by then after enough time has elapsed and no issue is fixed, they most likely will discontinue the device andoffer you a different one, passing the customer on to a whole new set of problems. Welcome to America, where its a dog eat dog world and we are all wearing milkbone undies.

[Q] 4G LTE issues with CleanRom 5.0

Hi all,
i have some questions about CleanRom 5.0 however i don't have the authority to post in it's forum, so i'm hoping someone can help me out here.
overall the rom is incredible, my only issue is the speed of my 4g lte network. it is much slower than what i am used to.
using speed test i consistently get about 12mbps down and 8mbps up, however if i go back to my stock nandroid backup so my phone is like it was before i went to cleanrom i used to consistently get about 23mbps down and 16mbps up. is this normal for cleanrom and if not is there a way to fix it because now the speed is about half of what it used to be.
i should probably also mention that i flashed the new radio and rpm that scrosler provided links to in the second post of the cleanrom forum

I've seen it stated many times that roms won't affect connection. Likely it is the new radio you flashed. You can always try flashing the old radio and rpm. Someone with s little more experience may have more insight.

Gotta agree with this. Roms do not change/impact your signal.
OP, flash another set of modem/rpm or even return to what you used before. Personally, my data speeds were below what I'm used to when using the latest modem/rom. My experience is nothing more than anecdotal and a single trial. I switched back to a prior modem/rpm combo and have enjoyed my normal speeds/LTE access.

Thank you both very much for the responses. I will try flashing the old modem and rpm to see if that solves the issue.

[Q] Will a different radio fix this?

Hi everyone, I'm running CM10.0.0 Skyrocket with UCLD2 modem. I live in Jupiter, FL and when I am traveling through town and pass through areas that switch between HSPA, 3G, and 4G, I often have to toggle airplane mode to get data back. Is this due to my radio? I was doing research in the forum about the various radios and I couldn't find a definitive comparison of the various modems to each other with a chronology of release. I'd guess that newer modems are better, but then I read that sometimes that's not the case. Anyone care to weigh in on why I lose data connection when traveling through different data zones? btw i checked my APN settings and theyre fine.

I too run into the same issue but when I'm at work I know that if you running jb data loss has been known to be an issue with it yes the newer the modem can potentially fix or issue depending on situation best option is test

Just an update, things still seem good with CI3 compared to my old radio. Only thing I notice is it doesn't really like 4G data, it'll say 4G and have good bars, and I can make and receive calls fine. But if I go online it'll stall, and I'll watch it struggle and then swap to H+ and be fine. That’s the only remaining quirk. Not sure why it's doing that.

I fixed my reception with 4G accidentally, i flashed the Lightning Zap v3 kernel to improve battery and lo and behold, reception hand off is fixed!!
