[Q] Radios...whats the big deal?

I've found the forums that explain to me how to flash a custom radio, but I haven't been able to find a thread that explains why I would want to do it. What are the advantages and disadvantages of using a custom radio and what are some good radios for my DInc with CM6.1?

all radios are good in the same sense. Ok basically a different radio can give you better signal or battery life or both. Or it can kill your battery faster and give worse signal. It's a case by case basis and I think mainly where you live matters.. I always stick with the 7.28 radio its been the best for me but its also terrible for some people.

Thanks for the input. I suppose I need to educate myself more on the different radios available because 7.28 doesn't really mean anything to me. If you don't mind me asking, what type of area do you live in that 7.28 works for you but not for other people? Is it the difference between a metropolitan area and a rural area, or is it more specific like better in a certain part of the country or city than another?

It is more of a block-by-block basis. I had an Eris in Chicago *Belmont and Central* and updating the radio helped immensely. But, went 2 blocks east, and lost all signal. Now I have a Dinc running the leaked Evo (11.09) radio, and notice better signal in buildings (Glenbrook South HS)

Also 7.28 is the newest stock Verizon radio. Radios are usually known by the last numbers in the name.. Radios are risky business as a bad flash can brick the phone. I'd read up and hold off if I were you... I'd hate to see someone break their phone its really a travesty when it happens.

How do I update the bootloader?

Hello!
I've been having bad receptions/signal loss on my GN.
People have been recommending me to update my bootloader, but how do I do it?

1. Assure you are bootloader unlocked
2. Go into bootloader mode
3. Download http://forum.xda-developers.com/showpost.php?p=20725207&postcount=2835
4. Double click fastboot-windows.bat (windows only)
5. Done
6. Reboot
And your problem is most likely radio related. What radio are you using?

Bootloader isn't going to do much for signal, you want radio. See this thread and this post

The thing is that I already have the PRIMEKL01 bootloader with the KK6 radio.
How come I still have huge problems with signal loss on 2G/3G?

Because that nonsense of a magical bootloader helping or stabilizing signal was....nonsense. Same for battery life.

Well, my reception is good enough - but I very often get signal loss meaning and reception is gone completely for 30-40 seconds before returning as nothing happend.

I still don't understand why you continue to "join" these threads and mention about these absurd debates in previous threads because they honestly really don't help anyone at all but cause drama. But okay.
@OP: Settings -> "More" (under Wireless) -> Mobile network settings -> Access Point Names -> Bottom right, reset to default.
Try playing around with different radios around the forum. See if one of them will prevent the dropping of signal.

I use XXKK6 but you have a bad experience with it. Usually "XX" radios are optimized for Europe. But it doesn't really matter, I live in USA and I use European radios.
KRKL1: http://forum.xda-developers.com/showthread.php?t=1439217 (Korea)
UGKL1: http://forum.xda-developers.com/showthread.php?t=1430107 (North America)
UGKK7: http://forum.xda-developers.com/showthread.php?t=1382699&highlight=radio (North America)
.. also, google "hashtab" and verify it's MD5 hash (do not flash a radio without a MD5 hash provided.. thats my recommendation, flashing a radio without matching MD5 may cause problems but if its not provided then look at user feedback anyway, flash it only if you need to). I suggest you to go back to XXKK6 if you manually updated the radio to verify its MD5 hash.
UG = North America
XX = Europe
K = 2011 (11th letter of the alphabet)

Probably because if there's one thing XDA is great at, it's people spreading misinformation that they don't intend/realize their spreading.

More like people here just love to go into other people's threads and cause drama based off a person's personal experience. If it has helped someone fix their problems even though a person doesn't believe it, that doesn't give them the right to keep posting in there to bring the topic out of relevance to what the purpose of the thread was supposed to be.
We're all here at XDA to help each other. Not bash on each other's feelings. It was simply a matter of updating a bootloader, and having a updated bootloader isn't going to make a phone become worse. No damage done, so is it really worth all of this drama and debate? I don't think so.
And I wouldn't want to continue this talk any much longer as I've dealt with it in the past 2-3 threads. Thanks, show was good, but let's move on.

Shoot, I'm on 4.0.2 with 4.0.3 bootloaders/modems, although in a lot of the weak signal areas around here I think I might be better off reverting back to the 4.0.2 modems.
What the other poster was trying to say in a not so nice way is, "Feel free to update your bootloaders. There's no harm that can be done and you may have a slightly smoother ICS experience, but don't be under the impression that it is a solution for making a significant difference in your battery life".
It's not helping to mislead people. Not that anyone in this thread has, but to the new user, there are a lot of things that are misread. New bootloaders and modems probably WILL make the OP's ICS experience somewhat noticeably "better", but they do not solve the OP's desire, which is to get extra battery life.
It's going to be very frustrating for people that think that new bootloaders fixed their problems, only to have their problems "come back" (because unless your original bootloader is just plan trash, your battery life difference is negligible) which will lead to more of the same types of posts that are all over XDA that are chalked full with a lot of opinions and not a lot of proof, which only leads to an over saturation of conflicting information when people use the search function.
But I agree, dude coulda been a little more tactful. And to the OP, flash a new bootloader/modems. It really can't hurt. I'm on Revolution HD which is already fast/smooth, and there are places within the ROM that smoother/quicker with 4.0.3 bootloaders/modems. Also, when you say signal loss, do you mean you'll go from 2G/3G to nothing, or from 3G to 2G sitting in the same area? It's not a fair comparison since I'm on Verizon, but I've had some times where my signal drops for no reason. A buddy of mine's Rezound is that same way, living in the same area, we think it may be a tower issue. Although I do see times where it happens in other places.

What is this 'tact' thing, you speak of?
/me runs off to Google.

[Q] Is there an external for the SGH-T989 ?

External antenna
I activated my phone yesterday and my signal is weak and very spotty. Sometimes I can get as high as 4 bars, most times 1 or none. If I can't get something to boost the signal, I'll have to sell my phone and look for something else. Is there anything sold or any mod I can do to boost my signal? Many thanks, for any help I can get.

Have patience with me. This is my first smartphone. I don't know what a radio is in this context and who and where can I find this Mr x thread?

ok I now know what a radio is, but is a hacked version better than the stock version that came with my phone. I just got it yesterday and I don't want to mess anything up. I don't know enough about this stuff to fool around with it just yet. I am trying to learn so that I can IMPROVE it's functionality. Notice improve, if it will not work better than stock, what's the need to change anything?

Radios give different mileage depending on your location. Which is why the above poster suggested trying different radios because in your particular area you might get better reception with a radio other than stock. You'll need to have your phone rooted in order to flash new radios.

Thank you for the quick reply. If I can't find a hardware solution, I may gather the courage to try a new radio. Is this the software or is it firmware, that I need for the T989?

I'm not sure what that list of files is but whatever it is, it's not applicable to our phone either way. The galaxy s2 they have listed is the I9100 which is the international version. We are sgh-t989 and any software or firmware is not cross platform.

Ardent are you in the Phoenix area? If so the kl1 modem is the best.

No, I am in Appomattox, VA. I live in the county, not the actual town. I know for sure that I am 7 miles from a Novatel tower. I get mostly a signal with 2 to 3 bars, that's between -100 and -92, respectively. I an using a U727 data stick on Ntelos 3G network. It wasn't always that way. I used to get practically no signal, until I cleared all the trees on my property.
I got the link in my last post from the following link:
http://forum.xda-developers.com/showthread.php?t=1426001
and it says at the top of the page that it is for the SGH-T989 series, that would make one believe that our phone is supported by it. I believe that it was derived from the SGH-T989D to be exact.
Someone please chime in, if I'm wrong. I have been getting, what I believe to be a lot of contradictory info here and for a newbie such as myself, that will only impede my progress and send me scurrying post haste to some other "authority" on the subject.
There does not seem to be anyone here who will correct faulty procedures. I understand that no one here is liable for bad advice, but believing that many here are proficient at modifying these devices, people come here to seek advice.
I need to increase my signal, either by hardware or script, can someone please help me resolve this issue?

you don't really need to because you can always return everything and get out of contract without ETF since you just activated. Just saying you can use it as a trial run and if reception sucks you can go somewhere else. You can try the radios but for what it's worth, might not produce any results.
You can probably safety use any of the ones in the link you have, and I think anything that screws up is recoverable. Any screwup will just mean you get no signal at all. Just flash back to the stock one which you can easily find with search.

No I am not in a contract. I would have to sell my phone, which I really like. I am using T-mobile prepaid. I bought the phone on eBay for $500. It has a clean IMIE as verified by T-Mobile Customer Service. I have bought over $125 in accessories also and would lose too much selling everything.
So I prefer to try to resolve my weak signal dilemma before taking such drastic action. Is there anybody out there that can help?

[Q] T-Mobile Modems

So, I was doing some reading around a few of the majors posts and realized that I should probably update my modem. I'm running an older version of CM10 nightly (11-14, really stable and hesitant to upgrade to CM10.1 due to a few issues it still has). The modem I have is still the Out-of-Box modem that came with the phone. If I update to UVLJA per the modems post, is there anything else I need to do other than flash the modem? What are the benefits of updating the modem?
Thanks
Ref modems post: http://forum.xda-developers.com/showthread.php?p=31409259

Just flash and reboot. I've done a few and find the latest to be best for me with signal in places I usually didn't get a signal. Although it might have a negative effect also. It depends on where you are located, what buildings you are in and so forth.

Great, thanks. Just flashed the new modem and the connection seems smoother already.

Good news

You can safely update to CM10 12/16. That's the last CM10 nightly. I ran that build for weeks and never had a problem.

Some people including myself experienced issues with that nightly, I had reboots with it and calls having delay issues (it would ring but I could not answer it until after the 3rd or so ring)... besides he isn't asking which is the latest nightly he should use.

Giving opinions on closely related topics is no longer allowed here? Thank you for pointing out the issues with reboots. I have not personally experienced them, however.

What works for one doesn't always work perfectly for another, no point in arguing about it.

I just went on a modem flashing rampage.. Don't know if it's best to let the radio sit or not but I found the UVLI3 modem to be best for me according to speed test. I'm in the NY/CT area and used the sonic tools modem flashing kit. I Got 13mps which isn't bad lol

PRL Updated.

My PRL updated to 61009 and I'm getting horrible to none connections with cell towers. Was wondering if anyone had any PRLs between 61000-61008? or even something around the 60700-60999 area would be nice to try!
If so, I would be greatly appreciative if you guys could share it with me.

Honestly, all I can suggest is read all the prl discussions you can to include other Sprint devices. Just don't expect a magical speed daemon to arrive in your phone. It's about obtaining signal where you may not or other reasons that I'm sure you'll find.

How can you tell which prl is right for you?
Is it just trial and error?

Easiest way for me to answer is go read the op of the link I posted. I think you may be confused on why someone would want to change prl's..
:edit: I see that you're on boost. I don't think this will help you. Mvno's like yours may not benefit from this. May want to research this more before changing.

I'm researching the PRL, but currently mine says default. I'm looking in ==> System / About Device / Status. I'm wondering is that normal. I'm reading ppl have a # on their phone, but mine just says default.

Well, I have to confess, this is weird. I looked at my phone yesterday, and my PRL was listed as default. NOW, it’s listed at 21095.
Note, I’m still researching about PRLs.
