3g speeds whilst rooted

random question. i lived in new orleans for 4 years and during those years used a hero and an evo. both phones were rooted, and never had an issue with 3g speeds while rooted. i didnt root my e4gt until i moved to baton rouge, and the speeds were just abysmal. got on the phone with sprint, and they suggested i take my phone to my local sprint shop to see if it were a problem with my phone.
so, i unrooted the phone, and the 3g speeds went from roughly 50kbs to 512kbs. i even reached 1800kbs about a mile away from my house in a grocery store when typically i was getting 100kbs, at the most. for what its worth, i was using blazer rom with stock kernel. anyone ever run into this?

Rooted and rooted using a custom rom are two different things.

gotcha, but i guess i should have made myself more clear. both phones previous to the e4gt were using custom roms, and never had an issue with 3g speeds. i have tried just about every custom e4gt rom, and they all suffered the same abysmal 3g speed disease. maybe its just my area, but again was just wondering if anyone ever ran into this...

I'm not sure many (if any) of the custom roms for the e4gt have any 3g tweaks. The only thing that would affect ur speeds is what modem you have. I personally have seen little difference with any of them but it seems like fb15 is slightly faster than the rest for me.
Probably the one thing you can do is change ur proxy settings.
Dial ##3282# in phone.
Select edit
Type in MSL
select others
select mutimedia
Change addresses to 0.0.0.0
Change ports to 0
Should give you a slight boost.

thanks, yeah i tried that this morning, and interestingly enough made matters worse. well, maybe not worse, but not any better. i just found it very interesting that the speeds would be so much better with stock, thats all. at this point, i dont even think i am going to take it sprint because my initial call was because of the horrible speeds. now, it would just be a waste of time. lets be honest, none of use like going to sprint stores. again, thanks...

I love goin to the sprint store. Talkin to the techs is fun as hell.
Not as fun as XDA, but still....

ha ha! sure, sure. depending on my mood, i may make the trip. its not too far away, and i do love dealing with the indifference that is the sprint employee - at least the ones i have encountered. i know there are good/great ones out there, but the brick and mortar employees have been less than stellar.

How to Increase Signal in my Apartment?

I recently moved in to a new apartment for college and unfortunately my signal is very poor while inside the building.
This is really the only place on campus that I don't get great signal unless I get close to the window and pray that my phone decides to connect.
I've briefly looked into possible solutions but wanted to see if anyone had any suggestions/opinions on what I should/ could do.
I briefly looked into the Sprint AIRAVE, which I should be able to get. However, unless I can get it for free then I really don't see it as a viable solution, especially since my contract is up soon and I can just move to another carrier.
At this point I see my options being:
1. Get the AIRAVE.
2. Purchase a 3RD party signal booster (If cheaper than Sprint one).
3. Come up with some kind of DIY solution
4. Change some things on my phone in the hope that it improves.
5. Switch to another carrier.
What do you guys suggest doing/ think is the best option?
Are there ay other options I've missed?
Current Setup on my Epic 4g:
Rom: CM9 STABLE build from 8/10
Kernal: Shadow v0.6.3.3
PRL: FC09

I suggest option #1: Call Sprint and throw a fit, and have them provide you an airave

You may be better off with option 5.
The Airave is more of a cop-out solution for Sprint and their craptastic network. However, if it works for you then by all means go with it.
I've been with them for over 10 years now and haven't seen much network improvement in my city in the last 5 years. There are big patches of dead and weak signal spots all over. Hell, I can step outside my office building and find a dead spot in one 5 foot span, then move out of that span and be in a 3-signal strength spot.
I'm waiting a bit longer to see if their network will improve in my area. Otherwise, I will most likely jump carriers.

My family has used them for about 10 years total, with a brief break when we lived in england. I've never really had any problems with getting signal where I needed it before now. But yeah, at this point they better make a good offer if they want me to stay with them.

So I called sprint, they wanted me to go through some troubleshooting stuff and ended up asking me if I was rooted.
I had a bunch of back and forth with him and he claimed that being rooted/not on stock caused my phone to show no "vital signs" and that even if I am using the proper PRL it doesn't matter. Everything he said sounded like a bunch of policy stuff and he never gave a clear explanation of why it mattered if I am rooted. Anyways he said I could restore to stock/factory settings and then he would call me back latter and we would troubleshoot stuff.
I am going to be doing the flowing:
1. Backup everything
2. Odin back to stock (non-rooted + update)
3. Go through the troubleshooting, even though I know it won't make a difference.
4. Hopefully get the AIRAVE for free.
5. Go back to my current setup.
I've also noticed that turning 4G on may actually make a difference in signal (Since there is 4G in atlanta).
Does anyone have in thoughts about this?
Am I wrong in saying that being rooted has NO effect on connectivity?

If you do anything with Sprint that involves troubleshooting, you should be on 100% stock. Also, never admit to rooting, even though there is that PDF from internal Sprint mail around these forums saying it's basically okay for customers to be rooted. It's way easier to just get back on stock and step through troubleshooting, than dealing with a script following CSR on the matter.
It takes an experienced flasher all of 3 minutes to get from stock back to previous setup or a new custom setup. So not a big deal.
Turning on 4G is an entirely different radio; hence you would have differing signal strengths from 4G to 3G.

Maybe try the nexus modem and see if that improves signal. Some people say it has and got rid of dropped calls. Samsung is notorious for making awful modems, but Google made the Nexus one, so it is better for me and most people who have tried it.

I know really shouldn't have admitted to being rooted but I think I kind of wanted to argue with him about it, just to see what kind of reasoning they give.
And yeah, flashing back to my previous setup shouldn't be too hard. I already know for a fact that going to stock won't solve the problem,
I'm still testing the 4G thing since I can't really confirm if it is actually boosting the signal or not.

@xboxfanj: I thought about trying that the other day. I have to be on a CM7 rom to use it, correct?

Now there is a patch for CM10 as well. Nothing yet on stock or CM9.

Yeah I noticed that. I tried switching to PA1.99 and using the nexus modem but it didn't have any kind of effect in my apartment.
So I odined back to stock fc09.
The Sprint rep called me back, I told him it didn't have an effect (because it didn't).
He agreed to send me the AIRAVE at no charge so I should hopefully have it in a week or so.
After I get it all setup I'll update this thread with details as to whether or not it actually solves the problem.
Now time to root my phone again...

Received the AIRAVE today. Took a little bit of fiddling to get it setup right.
I now get pretty consistent signal, generally 5 full bars, throughout my apartment.
My only real complaint is that it decreases my internet download speed from over 100Mb/s to around 40Mb/s.
The decrease is unavoidable since I have to use the AIRAVE router functionality in order to have it and my computer hooked up.
However it did seem to increase my upload speed by about 5Mb/s once I increased the limit it had set by default.
It also seems to causes me to receive texts twice but that may have just been a one off thing.
Overall it has solved the issue and since it was free I can't really complain.

The double text is an occasional thing and probably will never happen again. I hooked my airave to my router instead of the modem as suggested and it works just fine and does not interfere with my throughputs.

This is how I have mine set up and it works perfect.

Mine is setup so that the AIRAVE connects to the wall and then to my laptop (it's probably hooked to a router/modem somewhere but it's dorm internet so I have no control over that).
It would probably be faster if I hooked it through a separate router but I don't really want to spend the money on one, and would need a pretty decent one since my school has one of the top 10 fastest internet connections in the country (if I had to guess number 3, behind the pentagon and google fiber).

Modem suggestion for Miami, FL

I just upgraded to Blu Kuban ROM, and I want to try a better modem here in Miami.
Any suggestions?
Thanks

Try fi27 first. Then its just a gamble. At least with cuban you can pretty much download all ics modems. Although there are still people on el29. Good luck man

Yeah like patrao said its a little like Russian roulette, you just gotta try em and test em to find one that likes your specific device and area. There seems to be some small differences between the hardware radios and towers where even ppl in the same location get widely varying results on the same modems.

thanks guys...a dumb question....how do you test the new modem? look out for dropped calls? speedtests? what do you look for?

I usually use speedtests for data, and in about phone/status check the dbm the lower the better signal u have. Usually -90 to -95dbm is decent -86dbm is perfect and -120dbm is essentially no signal at all.
Edit: for speedtests I use ookla speedtest.net app and FCC test app, I will also tether both USB and wifi and run speedtests on the PC and write down all results and then avg them out for each modem and then go with the one that gives me the best/most consistent results. I usually run my tests over a 24-48hr period per modem, and its best to test from a tw rom so u can update prl and most importantly profile after flashing the new modem.

4.2.2 OTA signal question

Hey folks,
Just a quick question I was hoping to get some clarification on:
Like many, I got the 4.2.2 OTA on Tuesday evening and everything went fine with the download and install. That being said, I'm having some signal issues that are a bit strange. For the most part the signal quality is fine. Not really having any connection issues, but I've noticed lower bars being shown overall. After doing some digging though I've determined that apparently 4.2.2 reports signal quality differently than 4.1.1 did... representing a much truer value based on dBm and not overly inflating things for constant 3-4 bars. Essentially it's like I remember way back with 4.0.2. I still find it a little odd that I can show -85dBm and only have 1 bar, but if that's how things are reported in 4.2.2 then so be it.
The thing that's bothering me though is this: at times my signal will read 0dBm 99asu. I'll have zero bars showing, but it will still show 4g in the notification bar and will say connected to the network in status. I can make calls, text, surf the web, download apps, even run speed tests without any problem (although not great numbers, they're not horrific either) Eventually bars and dBm "come back", but the amount of time for that to happen varies. Again, nothing seems to be affected by this, but it's just a little disconcerting to have happen.
So, has anyone else experienced this? Google searches show some talk of it but otherwise haven't turned up much. I've done a battery/SIM pull and that didn't change things. Is it possible something may have gone a bit sideways in the ota download? Was thinking a factory reset may help too but not looking forward to wiping my device only to find out this is pretty normal.
Any help would be greatly appreciated. Thanks in advance.

It's possible that the OTA updated the baseband, please look into that as I'm not entirely sure. If that's the case, then it might just be that the new baseband is not suitable for your coverage area in which case I'd suggest you flash a previous release.

Thanks for the reply. I'll fully admit I'm not as up to snuff on this as others, so please correct me if I'm wrong... but the 4.2.2 OTA did in fact contain new radios from VZW, so shouldn't the baseband have been updated for everyone who took it?
Mine is: I515.10 V.FK01/I515.FK02
As I understand it that breaks down to phone model (I515), HW rev 10, with the new radios being FK01/FK02
Wouldn't every VZW GNex that was on the 4.2.2 OTA have the same baseband; outside of having either HW rev 9 or 10?
Currently I'm locked, stock, not rooted... yeah, probably one of the last Thinking I may unlock and root and try the 4.1.1 radios again. Do I need TWRP or CWM to flash those or can that be done if I keep stock recovery?
As always thanks for all input, much appreciated.

My Gnexus is the same . but despite that it actually performs better oddly enough

Do/can you update roaming (*228) with the Verizon nexus? Or is that just something I could do with my old fascinate (yes, a fascinate and then nexus... I am a glutton for VZW punishment).

You can, but as far as I know you'll then have what is considered a 3G PRL pushed to your phone, something beginning with "5"... if you just let the PRL update and push on it's own like it's supposed to you'll have a 4g PRL, and will begin with a "1" Both work the same and pick up both 3G/4G signals...not sure what the true difference is honestly. I've been on 15192 for ages now and it's been fine up to this point... Think I'd just as soon keep it. Thanks for the suggestion though.

I Read some where online. That if you take out the Sim card let it for like a minute or so. Slap it back in and there you go. It work for me

Yeah, did that... battery pull and sim card pull... left it out for 30 min then back in... no difference. Like I said, it's not that I'm having a huge problem with my data connection, it's just acting... strange... kind of all over the place. Lots of fluxuation, odd readings/bar equivalents, and the whole 0dbm 99asu thing with still being connected. However I've also now started seeing higher than normal "time without signal" percentages... Just flakey. And frustrating... no issues at all until the 4.2.2 ota.

mine is not really a problem but I had way more bars of coverage in a multitude of places (work, home, gym, etc) on the old radios. I havent looked at the dbm's but visually it's different. might be something for someone interested to look into.
btw, im in fresno, ca.

Well Google changed how the signal is read visually through the bars to provide a more accurate reading. You should look at dbm
Toro | Xylon | Diamond

Having the same experience here (Whidbey Island, Washington) where the 4g signal clings on until it absolutely had to fall back to 3g. New radios may be contributing, but the change in coding to report lower signals may have improved the ability to hang on to a 4g signal. Hand off seems pretty slick too, but that's likely a function of the new radios that came in the OTA.

[Q] Radio for Verizon Galaxy Nexus?

Well I hate to create a new thread but the rules on this website are weird and I can't post in the actual thread that would answer my question yet.
Anyways.
I'm on Paranoid Android 3.99, and apparently Verizon hasn't released a radio for 4.3 yet. Would that explain why I keep dropping Wi-Fi and 3G/4G?
Again, sorry to start another thread, but your forum, your rules I guess. Also you should work on the forum search, a lot of the pages it returned didn't even have my query text in them anywhere (via Ctrl+F).
Thanks.

I've been wondering this lately myself. I'm suffering from the same data drops that you are. Sometimes it takes 30 minutes or more for my phone to finally catch a solid connection. It's becoming unbearable.

I'm getting pretty close to going back to stock myself, especially if I have to wait for a radio from Verizon (2018 maybe?). Not much use having a fancy phone with the latest version of Android when all you can do most of the time is play solitaire, eh?

I've found that turning off LTE and just using 3G has far less issues. The city I live in has spotty service at best due to topography, with LTE coverage only in half the city. I think the 3G/4G handoff is the culprit. This is apparently a known issue as shown here - http://www.androidpolice.com/2011/1...other-4g-lte-vzw-phone-is-losing-data-signal/

Interestingly enough, I went into my settings to see if turning off LTE would make a difference in my reception. My "Preferred network mode" was set to WCDMA when the only two options when I click on it is LTE/CDMA and CDMA only. Looks like it was manually set or something. I don't know if that is hurting anything, if WCDMA doesn't work then it should fall back to something that does, right?
At any rate, I set it to CDMA to see what that does for me. As for the link you posted, that does seem promising, but I'm inclined to believe this is something with 4.3, or heck, even with PA itself, because before I left the last 4.2.2 version of PA, my service was perfectly fine (relatively speaking... I live in Amish Country!).
Hah, it wouldn't let me post this because I quoted your link.
