4g connect faster and have better reception????

I just got a replacement epic cuz my old one broke but I used to have these "tweaks" (I guess) that made my 4g connect to lower signals and the same for 3g and another one that made 4g connect quicker
But now I can't find these threads
If anyone can find them can you please give me the links to them? Cuz I've been looking all day and can't find either one of them. Thanks for whoever helps

My 4G broke! My other phone connects fine but mine craps out trying to obtain ip address on 4G network. Thoughts? Reflash the modem? EFS clear? Call Sprint?

That is the post that I was looking for except the one I seen was on here on xda and it had more stuff like options for the 3g connections to make it better and also there was something specific u type into connect bot to get the msl and only the msl instead of a huge list

My 4G is fixed. Had corrupted data somewhere. An Odin to anything got it working, a nand advance data restore killed it. Restored everything without data in Titanium. It is still working now.

I can't imagine anything in the titanium backup that would corrupt the modem or kernel?

No Titanium did not but I had some bad system data somewhere, perhaps in the WiMax apps. So I used Titanium instead of Nand to restore apps only and then data to the few apps I had to have restored like memo and cardstar. All is well now. Only 4G was affected by this corruption that I got on a journaled ROM. Flashed the journal on script to be doubly sure this time.

no more 4g

I rooted my tmobile S3 today and it worked fine. Later I installed a cyanogen nightly sang noticed it was only getting 3g, so I did a restore to the stock rooted firmware through ROM manger. With that I got just bars, no indication of 4g or 3g. The phone wouldnt go to the internet, it said no connection available. I had to restore back to cyangen to get the phone just to work... but regardless of which settings I chose the phone is stuck in 3g. What is the fix? I'm going crazy here

3G on cm is the same as 4G on tmo stock rom.
Try checking your apn settings on the stock rom since I think your imei is fine, without it you wouldn't have gotten 3G at all, even on cm.

Wait, are you just looking at the icon without it doing anything. Many aftermarket ROMs will show 3G when the phone is doing nothing. It will show 4G or H when you make it work.

[Q] (Answered) Why do I have an I747M on AT&T?

I searched around for the differences between the I747 and I747M, and apparently it is the location... That brings up my question.
I got an I747M, but live in the US and am with AT&T. Should I be worried about anything?
Thanks!
EDIT: I have found that it is because I flashed KyanROM, which changed it from I747 to I747M. Is there any way to revert this change? I did try to change it in the build.prop, like a bunch of places said, but when I did, the phone would get to the Samsung screen the crash. I did a nandroid restore and everything was fine, except it is still showing I747M.

Nope.

It is no big deal I am with rogers and I flash i747 ROM all the times on my i747m
If a flash aokp or cm10 it shows i747 but if I flash stock it shows i747m. It doesn't change your modem or anything.

Flash only modems that are for your carrier.

The reason I asked that is because Kyan ROM is based on the 747m firmware. It still works with the 747, but the build.prop shows it as a 747m.

Exactly. Look at the title in the Kyan forum... notice the M after the 747?.. so.. youve entered the world of ROMs?.. time to study!! Read read and read again my friend or youll get flamed like crazy around these parts. The answer to this question and probably all your questions are available in Kyans forum.. theres a thing called the OP that has all the info you need about the ROM you flash.. make sure you read it in its entirety atleast twice before flashing , sop. The OP is the very first post.. also, how to get around your issue and get the AT&T bloat back is also found in that forum.. theres a search function that will reveal all your questions and dreams.. its like magic except its just the search function.

Thanks guys, I feel a little bit better about it now.
I am only worried about the model number, because I can't download any of the AT&T stuff from the market because it is restricted from I747M's (as they are Canadian, and AT&T has no use on those devices). Is there any way to change it back to I747 and get rid of the M? @daddymatt, I have spent a good 30 minutes searching, and can't find any way to revert it.

You will need to use a i747 based ROM.

Try changing device id to I9300 instead of I747. It's the international version and will serve the same purpose. Don't know for sure if this'll work, but i think I've seen it somewhere else.

How many lines in the build.prop did you change? I had to change 4 in order to get Bell mobile tv working while running an AT&T rom. Try this, change
- ro.product.name=d2att
- ro.product.device=d2att
- ro.product.model=SGH-I747
- ro.build.product=d2att
This should make your phone think it's an AT&T phone again, remember keep a nandroid handy just in case...

New to CDMA

Hi, I've been a 10 year TMobile user. I just switched to sprint this week. I'm not a newbie when it comes to flashing roms, but I'm wondering what differences I need to anticipate by using a CDMA phone over a GSM before I start flashing something and brick my phone. Any input would be appreciated.

*facepalm* Seriously people read before you dole out your half witted 2cents
All of my experience is flashing on CDMA, but to my understanding flashing a GN2 on CDMA is exactly the same as GSM. Make sure you only flash the sprint variant ROMS, but other than that you don't have to take any precautions.
BUT you dont get to have data while talking on the phone anymore. Unless there is that sweet workaround with LTE. I'm in a 4g free zone so can't confirm or deny this.

Do I need to reactivate my phone after each flash or is it similar to with a sim card and just flash and go?

You would use activation like changing a sim card - triggers the phone to go out and grab its new phone number, GPRS logins, etc.
"Update profile and PRL" are what you should be doing on flashes, expecially if you flash a new modem.

I flashed a new modem last night, didn't update profile or PRL. Works fine.
Changing ROMs is as simple as changing sim cards. If your phone was activated before, a new ROM isn't going to change that. This includes AOSP ROMs, when they arrive.

Thanks for the replies. Now I just have to get over the differences of HTC and Samsung. Didn't have anything like Odin or whatnot for HTC, but did have weird bootloader issues. Thanks again.

Yeah, it will work fine. Modem rom contains the PRL, or at least it did on the e4gt. Flashing a new modem may leave you with an older PRL.

Ok. Maybe I didn't make my point clearly. I was talking about best practices over time.
For example, the modern you flashed has PRL56009 which is the newest ATM. Great.
In a year, if you flash this modem again, you'll be back on 56009. Even if the new PRL is 56123.
Make sense?

My general rules:
When flashing roms, only update prl and profile if you notice a loss of data speed or connectivity issues.
When flashing modems, update the prl and profile.
Samsung modems were new to me when transitioning from HTC. Common thought is the performance of different modem versions is dependent on location and/or individual phones. You will flash roms and modems independently.

My point was I had manually flashed the corporate prl previously, which I don't think was included in the modem. 55009 is the current standard prl.
I'm not trying to argue with you. I don't claim to understand how modems and prls work. Just sharing my experience.

This is usually the outcome. Too many postings (fresh ones too) of people who just got s-off and went to aosp. When they came back to sense, radios sucked. Until those posts stop appearing I stand by my comment.
If s-off, the decrypted ruu should fix. Until, you repeat the same steps...and define insanity.

I am running PAC-Man rom. Signal is being measured by GSAM Battery Monitor Pro.
Voice and Data are working fine, just low signal. IMEI is not blank. Not sure what step to take next to diagnose the issue.

This is what I'm getting running PAC when I have full bars.
