[Q] Modems and loss of signal sph-d710 - Samsung Epic 4G Touch

Hello all i am new here. ive been rooting for a little while now and i have nothing but issues with my modems and connection. Im running The Blu Kuban ICS 1.0.4.0 with steady hawkins fd02 kernal with cwm. ive tried mutliple roms and kernals and every modem out there. every speed test i run on 4G i get under one meg. before on a stock el29 even rooted i would get 13 to 15 megs. but as soon as i install any rom GB or ics its dead. i am look for any suggestions i can get. thank you for your time. and yes im aware of looking around the site. i have not seen anything that really equals to my issues.

Too me your issues are not exactly something the community can help you with especially if you have tried everything out there. I would just odin back to complete stock and try your speed test again. If you achieve the speeds you want then I would then proceed with flashing roms only and do speed tests after every one.
Honestly the EL29 modem has worked the best for me and I am on CM9. I know you are looking for answers but I unfortunately don't know what they could be other than just keep trying. Different modems work better for different people in different areas. So the resolution for one may not be the resolution for all in this case.
Final choice may be what did you root your phone too do. If its just tethering then Foxfi can cure that with out being rooted. I guess its a matter of whats most important too you if you cant get back up to the speeds you desire...
Edit: Have you done Profile Updates after updating modems? Have you done PRL updates at all? Have you asked Sprint to refresh your data?

I have tried the prl and profile on about 75 of the modems ive flashed. some are 50/50 some see very minor jumps and some seem to decrease. i thought about calling sprint but i was nervous if they would ask about the specs that i dont have due to the phone being rooted and flashed. ive seen a post about how the phone may be stuck in 1x in the radio or something along those lines. but once i get into the debug mode all of the menus and everything that is packed in is way out of my league. im going to wait for the kuban update. i will start from square one and test everything out. EL29 did wonders for me stock root but once i flashed over to caulk or blu kuban it all seems to go down hill. i really like the layouts and the battery life thats why i always come back to a custom rom. thank you for helping me.

[Q] 3g signal weak after constant flashing??

Hey guys my 3g is not as fast anymore after constant flashing of roms and radios and now I never get over 500kbps..any suggestions?
I've been having the same problem! I seen somewhere about reconnecting your phone with Sprint towers, but can't find the post about it again anywhere.
Did yall try updating your profile?

Ive updated my radios, prl, profile..and I always do complete wipes and wipe multiple times before I install a rom..also I tried that data govenor removal mod and still nothing..i really dont want to unroot and bring to sprint to replace
Sorry but thats all i got. Ive noticed sometimes i get bad reception but i havnt up dated my radios since fresh 3.4 came out. Ive been running cm for a long time so that might be it but its not enough to make me flash back to sense to fix it. I hope you get everything figured out.

Hey no problem man I appreciated the help..I guess my next move will be to flash fresh Rom..the speed seems to come and go on myns rls 5 but on any other Rom speed is completely horrible but let's see..ill get back with results.
I've been having the same issues. I've noticed when running the speedtest app sometimes it detects the closest server being over in Europe (I'm from Wisconsin). It appears to be tower related. When I'm on the tower closest to my house it detects the closest location in Missouri? Awkward. I'm on CM 6.1.2 running snap 7.6 with turbo enabled. Most times I see speeds of .3 mbit. Turn on wifi and I instantly max out my connection at 8 mbit. If only 3g were that fast, lol.

Poor to none 3g speeds

So I'm fairly new to rooting and have been flashing a bunch of ROMs since I have and everything has worked fine but today I have noticed that I can very rarely get 3g in my house and a lot of the times its completely gone, I can't even get 1x. I have not messed with radios and I hadn't planned on doing so but what's going on here has anyone else had similar issues? I've flashed different ROMs after full wipes and still am having troubles. What gives?
Edit:
I am also getting really slow USB speeds. Like 10 minutes to put a nandroid backup onto my sd, this used to take a minute or less. What is happening and how can I fix my phone I'm going on vacation tomorrow I need it working
Do a full wipe in recovery, then flash this: http://forum.xda-developers.com/showthread.php?t=1087077
As far as slow SD speed, are you on an AOSP rom? If so, Chad's incredikernel will fix it. Look around on his thread, I think the latest release has it incorporated.
Yea I was trying MIUI so that's that problem.
Edit:
Whew you are a a life safer that brought back my great 3g speeds. I would like to know what exactly this did though and if I can flash new ROMs again and what might have happened to cause the problem.
Another cause for this to happen is that if u flash a Rom with Sprint source and u call the *228 it will mess your phone up and you will need to go back to the incredible official froyo to fix it... I had this issue my self ...

I thought I remembered hearing something about turning the phone on or off while in airplane mode causing this too, but I could be wrong. Glad that you got it working, if you have more questions feel free to ask.
I'm having problems with 3g as well. Has anyone tried applying this then going back to another rom?
It's my understanding that the GB leak fixes it, and you can go back to the rom of your choice after flashing it.

Seriously need Help. :/

I recently bought a used Epic 4gt, with a bad ESN, I have a GS1 and all i had to do was copy all my info to the new GS2. Im currently on boost my GS1 works fine so it was going to be pretty easy. I repaired the esn and flashed everything to GS2. Everything works except 3G. I tried everything I can think on from going to stock el26 to el29 to custom roms and back to stock. Tried using open DNS and changing APN to boost, with no luck. I have the 3g icon with up/down arrows and they flash. Under #data AAA-passes, it has an IP address, I get both 1x and 3G but when it comes to loading browser page or Google Play its no go. Tired different modems with no luck. I know my donor phone and GS1 are working just fine, with the same info applied as does the GS2. I dont know what else to try, I mean I get text and send text and make and receive calls, just no data coming in even with 3g icon present. If anyone can help me it would be great and will donate with paypal. GS2 currently sitting on EL13 modem with rogue 1.4.1 kernal and el29 TNZ blend 3.0 rom.
[email protected] in case i dont see the reply on the thread.
You've tried switching just the modems too right?

Problem Solved wheww
Yes, did try just the modem from EG30 to EL29 EG31 FC07 and FC14. *note the best signal i got was from EL29 and EL13, but EL13 seemed to make my epic4gt act different but thats just me.
So heres what happened, since i live in a brick house i get really ****ty signal, for some reason but out side i get like 2 bars to 3. Anyways all was copied correctly but since the signal was weak the whole time i was trying to get it to work and didnt make any progress i ended up tweaking my settings in qpst. so that that broke my 3g and when i went back still no progress so i was stumped.
the next day started fresh and decided to call boost and have them refresh my account which ended getting a new msid and getting a sprint rep error 16. after that i had to reprogram my incognito and gs1 back to working condition. and also try to get my gs2 working but this time i had to go back and forth out side to get a signal and see if the error 67 stopped from coming up.
had to get flash prl 60681 to be able to update the prl and update the profile on my gs1, same thing with the gs2. after numerous attempt's i got it working finally took forever to lock a good 3g signal. still slow even in good area but i guess thats how gs2's are. this was suppose to be a smooth flash turned to nightmare but all in all good experience.
if anyone needs help let me know i think i can be of some help since this incident.
currently on Calkulin's_E4GT_ROM_v3.0 rogue 1.4.1 el29 all working now.
I personally love fd19 modem, it works by far the best for me. But every phone is different. Feel free to try later fed modems.
Another thought of mine was, of you go to your phone dialer, enter ##8272# you should pop up with a menu. If you have your msl number you can change some setting. If you click edit > others > multimedia and change all the proxy values to 0.0.0.0 that may help with speeds. There is a legit walk through on how to do it but this is all just off the top of my head.
Sent from my SPH-D710 using XDA
Yea, I had already zeroed out the proxy settings. dont know if it helped but i did it anyways.
I'll try other modems as soon as I get a good feel on el29 and might give el13 another try.
thx for the tip tho

How to fix Call Dropping ???

I've had this phone about a month, and I can't have a phone call longer than 15 minutes without the call dropping. It has nothing to do with my location, because I have an Evo and older Epic in the same house and neither of them have a signal problem.
I have tried multiple PRLs and modems, including EL29, EK02, and many of the newer ones like FD19, FD24, FD26, FE07, etc.
Some of the newer modems were terrible, in that once I got loss of signal it would stay that way and I'd have to reboot. With EL29 and EK02, the loss of signal appears for only a few seconds, but when that occurs during a call the call drops.
seems like a weird issue, and looks like you have explored software related issues. One thing you could try is a network reset and force the phone to re-activate on the network, you will need your MSL though. If your device is rooted then you can get it. once you have your msl, go to the dial pad and do ## 72786#, it will ask you for your msl and should reset, this just clears out your programming information and should force the device to go through hands free activation. Not sure if it will help, but I don't think it could hurt.
Tried that also, same problem.
You stated that you've changed prls and modems. Have you tried any different roms?

I'm currently using Blazer 4.1 ROM.
One thing I've noticed, is if I turn off 3G data, then the Loss of Signal occurs a lot less often. Today I had a 40 minute call that didn't drop once I turned off 3G. Before I turned it off, I had 5 consecutive calls drop before they reached 20 minutes.
However, it's not a total fix, because I still get Loss of Signal from time to time with 3G off.
ever find a solution to this? this seemed to only appear when i went from a GB to a ICS rom.. but even after i flashed back to my GB rom/older modem, the problem is still there..
Ive had issues network related on mine. Certain roms well kernals mess with things that need left alone. Are you running one of the LOS kernals? I had constant issues with them. Try doing a full format then flash to stock unrooted eg30 then use ota up to ics. Then flash on. Ive fixed many issues with this method. IT seems when we flash flash flash it messes with it. But flashing back to true stock formated does seem to help

i'll try that, i do remember trying to flash back to stock ICS while trying to fix things and that did not help. i would have figured just restoring my old GB rom would fix things but seems the network issues were stuck.
Thanks

Pageplus ics data issue

I got my evo 4g 2 days ago.I use pageplus for my provider. I had to flash the evo to get it to work. Everything went great. On any gingerbread rom everything works. I have tried every ics rom and everything works great except i only get 1x data.I'm not sure if it is an apn issue, but i dont know how to change the apn in ics. Any help would be greatly appreciated.
update
I know now its not the APN. I didn't realize that had to do with mms and that part works great. Weird thing is i can flash back to any gb rom and i get 3g again. I understand it might not be true 3g but you can tell a huge difference from the 1x i am getting on any ics rom. Does anyone have any ideas what i can do to get the 3g working on the ics roms?
have you tried rebooting 1 or 2 times after the ics flashes? usually that clears up a lot of problems people have when flashing the ics roms. i personally have never had this issue and have always been on sprint so i can't really help you but figured id throw this at you
edit: also what ics rom have you flashed because im running the team D.I.R.T. cm9 port and its simply flawless so far
Thanks for the advice. I have rebooted many times, no luck. I tried every ics rom i found in here. Everyone drops my data to 1x. As soon as i flash a gb rom i get 3g back. Is there a setting i need to find or a way to force it back to 3g?
in miui i think there is a setting to force 3g but i think thats the only rom that does it. gb or ics. so im not really sure about straight ics. sorry
