Well it mostly depends on what rom your using, what radio your currently using and if you are happy with your data speeds....
Yes it is possible to brick your phone....but if you follow instructions and always make sure you md5 checksum matches up....most people dont have any problems.

Well I'm using the RCmix kingdom rom....and I would like to try another radio. But a couple posts said that flashing a radio didn't really do much for a phone...what should I look for when trying to pick a radio?

From what I've read...most rom developers usually have a specific radio they suggest to use with there rom.
And if not, it's usually safest to stick with the stock radio's. I've had the best luck with the most recent radio released by AT&T....26.06.06.30_M

Personally from my experience, I've had nothing but kinda meh luck with radios and data speed since I rooted my phone. I've gone from 2mbps download and 1.5mbps uploads to around 1mbps downloads and 100kbps uploads, at best. I've tried a handful of radios and roms both, and so far stock is showing me the best results...But that's just my experiences. Maybe I'm one of the unlucky ones.

Rerun the hack kit on the rom your using but when it get's to step 3, have the radio image you want to use in the folder of the hack kit and let it push that to the phone.
This will fix your wireless data speeds.

When you say rerun the hack kit, I take it you mean re-root the phone altogether or wipe and re-install the ROM? It's 4AM here right now so my mind is a little muddled and I wanna make sure I understood right lol.

Tried it, and still getting around 150kbps download and 70kbps upload.
Thanks for the help, but I think I'll just go back stock. No point in having a great device if I can't even use it on the web, or to listen to music without it stopping half-way through every song.

Just out of curiousity, what do the RIL even do?
For my problem, I've flashed the RIL, kernel, ROM, Radio, re-flashed the kit, kept the stock, flashed a dozen different radios with their RIL's and still...Nothing. Just stating my (bad) experience with Rooting, ROM's, and Radios. Kinda wish I could go back to how it was pre-rooting and get my 2mbps down/1.5mpbs up back, as well as having a stable connection back.

Your issue stems from the fact that your APN settings are fu*ked. Look up henrybravo's thread about apn settings in the dev section; it'll be on the 1st or 2nd page. If that doesn't clear your data speeds up, then post back here and I'll point you in the other direction. But, the APN trick worked great for me. I was *****ing about the exact same thing and everybody thought I was just too blazed or something because nobody paid attention until henrybravo figured out to change the access point names to the exact same entries as in the stock ROM. It works like a charm.

Talking about the MEdia.net and MMS settings that come with stock? I'm on stock now, and since rooting I've not been able to get my original stability and speed back. I dunno if the root kit I used screwed something up big-time or what, but I can't even listen to Pandora or Slacker anymore without having to unlock the phone screen, go into the app, wait a second, then it plays. Close screen. Rinse-repeat song by song. And it isn't like my phone is somewhere new; before rooting, for a few weeks before rooting, I'd listen to music for 8 hours every night or so there...After rooting, I can't.

[Q] Does ROMs affect Signal Strenght?

Hi, I recently obtained a new HTC Inspire 4G and rooted it in order to unlock it and use another provider's SIM card. I've noticed that using this phone with the other company's SIM doesn't work very well for me, because given that I'm at a certain place with that company's stock phone i have complete signal bars and when I use the Inspire 4g i only have like 2 or don't have service at all, which sucks... I just wanted to know if anyone can tell me if the ROM or radio on the rooted phone somehow determines the signal strength of some other provider service. Can anyone help me here? I would really appreciate it. Thanks a lot in advance.

ROM doesn't play all that much into the signal strength directly, but indirectly each ROM will have a different RIL which has a radio that corresponds to it. (Before you go well how does that all work, please see the radio thread in the dev section). So if you're changing ROMs and keeping the same radio (since I can tell you already know but I'll just make sure...radios don't change when you flash a new rom) you may be pairing a radio to the wrong RIL.
From your last thread and I'm not sure why you created two threads for this but whatever, you need to allow time for everything to settle in at least a couple hours. You may also want to check your apn settings if you're using a different carrier outside of AT&T. It may take some time until you find the proper radio/ril combo that works best for you. You need to allow some time for testing. If this is annoying to you or you just can't do it, unroot your phone and leave it stock because you're gonna find that a lot of these things are trial and error.

Bars are NOT a representation of signal strength. If you arent having it displaying your snr and giving those numbers, bars are meaningless. Remember the att fix for the iphone 4? they changed the height of the bars to trick people into a fix.

They're not completely meaningless. Each bar consistently represents a range of strength, and I think they can be configured.

Right but without knowing what that is, its apples and oranges. But i agree with what you are saying. Would be nice to configure at the user end.

APNs are going to affect your signal strength also. Just try a different APN setting and see if that helps. I'm sure you can find some by searching.

Thanks to all of you for your responses. I've not been working on that since I've had a lot of work and college but now Im ready. Ive got the part where someone said that it wouldnt affect, but the radio does... OK, I paired the ROM with the recommendded radio and still no changes noticed. So, I guess I'll have to change the ROM all over again. Can anyone recommend me a good one? Thanks a lot.

what? I'm unsure of what you're telling me or the OP? IF you're saying flash RUU to get back to stock then yes, I agree. Gene has made a wonderful tool that will help you get back to stock. But in general, no ROM will change your radio, you mustdo it yourself.

An official HTC RUU.exe will install a radio.

Proper Radio/Modem flashing?

Hello, I am hoping someone can set me straight on the flashing of modems/radios and what is the proper way to do it.
Do they have to be flashed during the rom flash and then never touched until the next rom flash or can they just be flashed any old time?
The reason I ask is because I was booting into CWM and flashing each Modem/Radio one at a time and testing them out. I narrowed it down to one that had the best call quality but after flashing back to it the quality was worse then it was the first time I had flashed that one. Is it possible for a modem to install differently the second time? I am not running any formatting or clearing anything.
Why would the same modem/radio give different call quality on different installs?? Should I only be installing the modems/radios at the beginning when I first flash the rom?
Would like to sort this out as my outgoing call quality is pretty bad. Tested my SIM card in my old Galaxy S on CM9 and it sounded a million times better. My Galaxy S2 LTE is on SKY ICS 4.2F6.

You can flash a new radio/kernel on your phone any time after you've flashed the rom (as roms usually flash a radio/kernal when you flash the base) and it should not have any adverse effects on your phone (unless the kernel/radio is buggy/bad for your phone).
As far as formatting/clearing, I habitually clear my cache whenever I update anything on my phone and I haven't had any issues with deteriorating call quality and the like.

That is strange. My outgoing call quality is so bad compared to my Galaxy S on CM9.
I just flashed my phone to CM9 RC2 and will see how that goes. Now I just have to wait for a friend to give me a hand testing call quality.
It's really strange how I had different results with the same radio but different installs.

I'm actually running CM9 RC2 as well and am having major issues with the radio that gets flashed with it (UCLF6) as I live in a test LTE area. The reception goes to 0 to full every 2 seconds and I never get any phone calls or missed calls when people call me.
CM9 RC2 seems to have an issue with the LTE toggle, Network Mode and "2G only" features. As soon as u turn it on, it auto switches back to the default LTE being on.
I did a little bit of research and found that I would need to flash a "RAT UNLOCKED" radio. My concern is the same as the OP in that I'm a little confused as to the proper method and steps to doing this. Any help is greatly appreciated. I think both me and the OP will benefit.
I've attached a screenshot of my about phone page.
Thanks!

I recall seeing those "RAT Unlocked" radios listed on Mohan's Embryo thread.
It can be seen here: http://forum.xda-developers.com/showthread.php?t=1754473
I have no idea if those radios can be used with CM9 or not but I'm thinking of trying the embryo ROM and seeing how my call quality goes.
My problem is nowhere near as severe as yours. I get decent signal and can receive calls fine. My outgoing audio just sounds horrible and garbled. Who knows, maybe my issues also has something to do with LTE.

That as almost correct. ROMs usually contain a kernel and the /system. They almost never contain a radio. That being said, yes, you can flash a new radio at any time. There are quite a number of radios for the Skyrocket because each ICS leak pretty much had a new one. You should have no issues flashing either a Rogers or AT&T radio on a Skyrocket. From what I've read and seen, different areas of the country do better on different radios. I would personally start with the radio from either the AT&T or Rogers official release and then work backwards from there.

The radios should work the same regardless of the ROM.

okay that sounds promising. to flash a radio do you simply flash the zip over everything on CWM? do u need to clear or format anything? once you flash do you need to change any APN settings or anything? sorry if these questions seem novice but i usually just use the stock radio. fist time doin this
Also: Where can i find and download the official rogers modems?

HMM.. Any idea why I would be experiencing these problems then? Just seems strange that I installed the same radio twice and it had different results on each install. Do you think it could be a phone hardware issue?
Would it matter if my phone is a Rogers and I am running an AT&T radio? Maybe I should try the Rogers radios?
@Ompalompa287
From what I gather... Just flashing the zip in CWM is all you need to do. No settings to change or anything. I have heard of some people wiping cache as well.

I just simply need to know if there is anyway to disable 3g (force to edge) network? I have a at&t Skyrocket running cm9 Chopsticks.

So I just found out my phone has Noise Cancellation for the microphone. Maybe it's the noise cancellation mic that is causing the issues.
Does anyone know how I can disable the noise cancellation to test this theory?

since cwm does not wipe the radio, flash new radio two times, even three times just to make sure it completely overwrites the old one you are replacing

[Q] Got GSIII and reception is terrible

It's easily 50% worse than my last phone (palm pre 3) and I've never had issues at my home with anyone's verizon phone.
I did flash LK1 RPM and Radio from this thread: http://forum.xda-developers.com/showthread.php?t=2007414
I'm not sure if that has any bearing on it and am also not sure if it was like that before. I did it all when I was in town.
Is there another radio I can flash and see if it's better? Or does the GSIII just have garbage reception on the outskirts?
TIA TIA

Diddo on all that..here is a list with all the modems.let me know if you find the best
Good luck

I've tried the miui 4.1

and the mean jellybean one I posted above.

To be honest when I first flashed any ROM on to my GS3 my reception was terrible. Every ROM that I used was the same, I also tried every radio available.
My only solution was just to go back to stock which I did now this Stock ICS has me at 4-5 bars everywhere I go.
My last CM ROM had me at 0-1 bar in the same places.
I hope this helps.

Check to see if you have the updated prl version 15154. Do this by going to settings, about phone, status. I think that is an updated list of the towers and that could be your problem. If its not the updated version just shut phone off take out SIM card for 2 min and then just start it up and it should automatically update. I read this somewhere in another post and just figured i'd pass it on. Hope it helps.

Txs mike..I was on something like 14015::' 1 month of fiddling of different modems and radios

Unfortunately I'm already on this PRL
Going to try some ICS roms I guess.

I have tried each radio as they have come out with mixed reviews. Some are better than others for me but YMMV. I have found the latest VRLK1 is what works best for me. I came from the Thunderbolt, and I really miss the reception I had with that phone; however, that is the ONLY thing I miss about it. I am currently running CleanRom v5.0 and VRLK1. I definitely get the best reception, and can maintain 4G at work while the other radios would drop to 3g or 1x. I only hope it continues to improve, but I don't think it will ever be as good as I had with the Thunderbolt. Good Luck.

Did you try all the radios, even the ICS ones.

I tried every radio I agree the newest seemed to work best but still was ridiculous. Barely any service even though I had two bars at times. Not enough for a single call and had to be by a window to get spotty text service.
Traded for a lumia 822. Works perfect.

This is funny. Coming from the nexus this phone has way more signal and better reception. Instant switching from 3g to 4g and to wifi. Ive tried every radio and they all work very well. Tried on my nexus and all were horrible. Just my .02 cents but this phone rocks.

As others have said try out all of the older radios and use whichever one works best for you. Unfortunately, this phone is not particularly known for having a strong radio (and no software update is ever going to really fix that).
If you are really on a fringe area of service, this might not be the best phone for you. In my experience, Motorola phones have always had the best radios in the industry, and are the most reliable in fringe service areas.

Trying to figure out poor signal strength issue

Hey guys!
Since I got my Nexus 5 a week ago, I'm experiencing a very poor performance of the signal reception at my office. At the same spot, Nexus' signal is around -103 dBm whereas a Neo or Arc S is around -93 dBm. Translated to bars, Nexus has 2 bars using EDGE and the others have 3-4 using HSPA.
I've tried to disable 4G, even for testing purposes I disabled 3G, but the signal strength is the same. I have read that many people have issues with the signal, either this same issue or other, and I got two Nexus with the same behavior, so I don't think it's due to defective devices.
I have noticed that the wifi drops some times and that the Nexus makes more noise on the speakers of my computer. Hence, I think it's a problem of some sort of interference produced by the Nexus.
Checking the testing menu (*#*#4636#*#*), on "Select radio band" at the "Phone information" field I only see "USA Band". I live in Spain, do you think this may be the source of the problem? If it is, how can I fix it?
The version 4.4.2 neither improve nor worsen the signal strength.

You have a problem with low signal strength. The .23 radio seems worse in that regard so get the .15 or .17 radio and test to see if it's better.
