4G Versus E - AT&T Samsung Galaxy S II Skyrocket SGH-I727

This is sort of a two-fold question. I've searched the forums, until other responsibilities interrupted, but can't find a good answer. I recently unlocked my Skyrocket to use with Tmobile and flashed ptmr3's Sons of Android Rom to replace the I727-UCLD2-oem-rooted Rom (per excellent post by lart2150) I used to get the unlock. Although the baseband version remains UCLD2 (of course) I've noticed that my 4G signal I had initially gotten on the oem rooted rom has diminished to E (post SOA flash). Not that it's a drastic thing but if if I can fix it why not. Also, would flashing a T989 (Tmobile variant SII) Rom be a good fix? I'm reading up on it when time allows but any direction would be appreciated, as always. :silly:

Thanks! Feel free to remove. Got the radio flashed. Other than the Tmobile rom question, which I didnt venture within the SOA post.

If you're not having any problems then there's no need to change your radio, unless you're just wanting to experiment. 26.06.06.30_M works very well with CM7 if that's what you're using now.
26.03.02.26 is what it is on. Is mine just a standard one? Should I put the other on

If you do wish to change the radio and Ril combination then check out this thread that I provided a link for. There is a lot of good information in it and you can grab the files from there. Just check MD5 sums before flashing.

Edit: I see Henrybravo caught that you are using a very old radio. Follow his suggestions and change the radio out using the radio thread files and instructions which are posted there.

Now that I see your radio version, I'm going to change my tune slightly. Your radio version is an older downgraded version leftover from the rooting process. It came with the first wave of DesireHD phones at the end of last year but never came with the Inspire (although it still works). I'd suggest putting 26.06.06.30 on your phone. It's the latest stock radio and works well with most ROMs. As Wolf_2 said, check out the radio forum.

I swear, this is the only "flaw" with the hack kit, and it's not the hack kits or Attn1's fault, and it's not really a flaw, more like an unfortunate side-effect for noobs.
This problem comes up so often for new people who root this phone.
They think they're done when they get to the end of the hack kit process, and then, low and behold, we get these threads saying "my signal/wifi sux," and when the baseband version comes to light, it's...you guessed it... 02.26
Most people figure out they have to flash a working rom, but enough people don't, to where these threads are a regular recurrence.
All my stuff works. Dont have any problems. Just wondering if it makes a diff if im on a another one. Just curious thats all. I read about them and know its user choice.

Radio and modem questions

OK since this is a question I'm assuming that I post this here so if I'm wrong sorry. And I have searched for answers to these questions on xda and Google and if info is out there I can't find it so if someone knows where it is point me in the right direction and I'll read the info myself as I'm not to lazy to research info when I can find it now that that's out of the way my questions are as follows...
1. What does the modem in my phone control the wifi or data and basically what does it do? The quick version will be fine.
2. What does the radio do and controll? Quick version OK.
I just updated to the latest ics leak that came out a couple of days ago I think it UCLD2 correct me if I got that version wrong. I've also tried UCALC4 and with neither I get many bars. On gingerbread I got 2 or 3 bars in my home recliner with UCALC4 I got 1 and with UCLD2 this new leak I get 0. I've read flashing the galaxy note radio will fix this if so I need a link to that radio with instructions on flashing it in cwm. And if that radio does not fix the problem can I flash back to this one or maybe a gingerbread one?
And lastley I'm getting a notification at the bottom of my screen every few minutes that says connected to belkin wifi etc. I did not get this on gingerbread is this also a radio problem or a modem problem or a tottaly different issue? And what can I do to fix it? Should I just restore the backup of gingerbread I made and wait for the official update whatever year that may be lol?
Thanks ahead of time for any help or advice...

I typed "android phone modem" in Google and got an answer on the first page, I'm sorry but I highly doubt u searched anything. None the less, as a new user I will spoon feed u this one time
Radio and modem are interchangeable terms used on CDs to basically describe the firmware used to control your phones cellular radio. Different firmwares enable different functions and frequencies. Basically with no modem, u have no cell data, or signal. No calling, no texting, nothing
UCLCL5 has been pulled due to it causing too many instability issues. getting a phone that works with it is luck of the draw. Use leeC UCLA3 radio for ics instead

Sorry but I typed in cell phone modem and of course with that all I got was ways to connect your PC to the internet thru the cell phone. Didn't think about putting android in cause I figured modem would be in all phones oh well I will try that too see what I come up with. I'm in a real wooded very rural area so im not sure if the radio is the main problem I do know other phones like pan tech link a non smart phone gets full signal here but none of our android phones do. My main concern is the wifi saying connected every few minutes and my connection seeming like its slower that problem I did not have on gingerbread or UCALC4 is anyone else having these issues on the new leak

OK I flashed that modem that you gave me the link to then rebooted and BAM!!!!!! Instant signal bars... Thanks man you are awesome and I may be a noober but I'm learning a lot fast thanks to guys like you. I am a computer programmer/web developer/ net worker but phones are new to me but I'm learning in many ways there similar but in other ways miles apart... But thanks again.. oh yea by the way in baseband version it says UCALC4 but in build number it says UCLD2 but the modem I flashed said UCLA3 so I'm not sure what that's all about but its working so if it ain't broke you don't go messing with it...
Sent from my SAMSUNG-SGH-I727 using XDA
yeah, you'll learn about that as u go along, but they're basically different build numbers. UCLD2 is the newest, UCLA4 is the previous ics leak build, and UCLA3 is actually a gingerbread radio (2.3.6), but it works really well.
If I helped I u, and if others do in the future, hit the thanks button!

Yep, I used LeeC's UCLA3 modem for a good while. I tried the others but kept going back to it for the connectivity. Of course, everyone's phone and conditions differ so you have to try anything for yourself before you know if it is going to work for you. Like mentioned, it will probably show "Unknown" for a baseband, but it works. I am using the latest ICS modem (UCLD2) now with the Alien 7 ICS ROM and it seems to work just as well as the UCLA3 modem did for me.
+1 my wifi is even much faster and alot better range on ucld2 radio. Ucld2 is in every aspect. Far superior
Smoother. Faster. Less bugs
And easier to build from
I built my new rom. The ucld2 one. And did the themeing. In 1 afternoon.
Of course i have a great setup i ended up with from dealing with. The other leak. But i still say its much more refined
The UCLA3 modem worked good for me no doubt but as you said every phone is different and I like to try new things and stay cutting edge so I flashed the UCLC5 modem out of the galaxy note and my download speeds are faster with it but like you said it seems to depend on the phone itself and I would suggest anyone who is gonna try a new modem to try each one for a day or two to see which one is the right fit for your specific phone...

Yea, it worked OK for me (a few fc's in the background) but nothing major, but I too have read about the troubles some people get from the Note modem. Like you said, its probably not worth the gamble...especially now that UCLd2 modem is out.
Scott can you post a link to a zip file for the UCLD2 modem. The post I seen it in the other day I can't find now. I lost all my favorite XDA forum posts when I upgraded to premium. I want to try it on my wife's captivate just for an experiment.....

[Q] Blaze 4G Modem in the UK?

Hey guys,
Sorry if this is the wrong forum but I looked at the Blaze 4G thread in the Development forum and searched but didn't really find an answer / didn't wanna revive the thread so anyhow, two questions!
1. Some ROMs ask you to flash this after flashing the ROM. Is that for speed or is it because the stock radio / modem gets erased / doesn't work as well with the ROM? Sorry, I feel like this is a noob question but I'm asking because some ROMs have custom kernels (which I'm guessing replaces stock kernal? Or maybe you flash that separately?) so if the ROM asks you to flash radio, is it because it doesn't have radio and stock radio gets deleted / doesn't work?
2. If they tell you to flash the Blaze 4G modem just for speed (and the stock radio doesn't get removed / works just fine), is it worth flashing it when where I live doesn't have 4G capabilities (yet)? Like would it mess up the frequency or something / change it from GSM status to like CMDA or something? sorry, ANOTHER noob question, OT but I read somewhere in XDA that they had a radio (or something, I can't remember what sorry) that could unlock Droid 4 from CDMA to GSM or something so I'm worried that flashing this might make it not work in the UK frequency anymore / not really be worth flashing because it wouldn't affect speed much anyway?
Its useful for internet speed and range. Its 4G only, so this wouldn't be of use to you, sorry.

Thanks for the reply! So I'm guessing stock radio would work as normal? I'm thinking about flashing GOV3 and it said to flash Blaze 4G after flashing ROM so I wasn't sure if it was necessary or just a preference
No problem. Well in your case, 4G isn't supported so keeping the default stock modem is perferred, this will present less problems.

Good feedback. For future reference, what network in Romania are you using? (I wasn't aware it increased signal strength on different carriers, but that's good to know!)

If it ain't broken don't try something that could break it?! Haha thanks for the info though if I'm having noticeable issues with stock radio, I'll look into flashing this!
How do I back up stock radio though? Not flash a version of the stock radio uploaded here, but the one that came with my phone? Ya'know ... just in case
Flash any ROM (I mean ANY) and it'll come back.

Connection problems with SUPERLITE CM10 JB4.1.2 RoM

I recently flashed to Vincom's SUPERLITE CM10 JB4.1.2 RoM | V8.0.
Ive gotten things up and running pretty well, but there is one major issue I seem to be having. My phone is not consistently able to connect to data on AT&T. I am frequently losing my data connections in locations where I have always had them in the past.
I searched around on his developer thread but didnt see an answer. I saw a reference to APNs for AT&T, but his note says these should now be included in the ROM I flashed, so Im not sure if I am missing something.
Anyone know if this is a common problem or how I can troubleshoot it and get up and running again?
Thanks.
Haven't heard of this being a problem. What modem (baseband) are you on? You can find it in settins, about phone.
Also, in settings wireless, more, mobile networks, Check that the access point name is on att LTE

Its gotten worse. Ive spent the last 5 hours with almost zero data access.
I see baseband version i727UCLI3.
Access Point name was was set to ATT wap,cingular. I switched it to ATT LTE (pta)...should this fix it? Any idea why this would have happened? Will I need to keep checking this or was it just something from the ROM flash?

reflashing radio is the simplest things todo on our phones, no harm will come of it and sometimes beneficial as cwm/twrp wiping and flashing roms dont touch that parition

[Q] Which radio should I flash on my Blaze S?

I have been reading up custom roms ever since I got my Blaze, and something new I didn't know i needed was an updated Radio for certain ones. Doing a little searching, there seems to be more than one radio I can flash; about three I've found. What radio is recommended? What are the differences? Is there enough of a difference for me to be concerned?

Uvmb1 is the latest radio for the blaze and is the most recommended. The t989 radio is compatible (from what I've read from other users) and should work. As far as which is better is a matter of how each works for your area. Try them both for a bit and see which one works best for your area. But the Uvmb1 is the radio the cm developer UberPinguin recommends...

In my area the 3G/HSPA/UMTS signal drops each certain time.
I've tested UVLB7, UVMB1 and UVLH5 radios but it doesn't seems to work.
Sure, is the area when I located, because in another part of the city the signal is strong.
I will test the UVMC6 radio in order to find out if my signal stops dropping
In MIUI, Stock and Avatar is the same results.

Check out the Blaze bibles for compatible radios. Benefits differ for each person. Some people are better with the uvmb1 radio while others benefit more from the uvmc6 radio. Flash one, try it out then try another

If you flash one not meant for your device, or if it's packaged improperly. Other than that, I've flashed several without any issues. When it doubt, though, let us know here, and we will be more than happy to help
