[Q]How to distinguish 1X or Ev-Do service we get on Epic? - Epic 4G General

I'm trying to flash epic to another carrier(in china). I've already flashed the imsi, esn, akey, aaa userid, aaa passwd. Everything seems to be fine(calls, sms...), except the data service.
The connection is extremely slow(got about 125kbps down and 120 kbps up), it seems the epic is using 1x not ev-do.
When i set "HDR/1x Selection" in ##DATA# to "Evdo Only", the "3G" icon is still there. I dialed *#147852#, selected "Testing" then "Phone information", i found that the "Network type" is "1xRTT".
WTF, I'm really confused by epic.... Since there is absolutely nobody talking about Epic 4G in china and I know that no one could know more about this phone than you guys on XDA, I really need your help!
Sorry for being a noob and sorry for my stupid english, but i just want things to be done, PM or posting welcomed, Thank you!

Put the phone in airplane mode then bring it out to have it update the EVDO Only.

You also need to use CDMA workshop and copy NV Items 465, 466, 1192, and 1194. That will get you 3G speeds.

I believe you can also use QXDM for the NV items. But CDMA WS is way easier.

While on this subject,i read somewhere that there is a way to force Epic and Evo to use Verizon network without roaming charges(since sprint and verizon share same towers),im upstate ny and sprint 3g service is not that fast,i would like to try verizon and see if I get better speed.If anyone knows how to do that please post it on here.

thank you for you remind, i had a reboot and with no luck... i wonder if there are other NV-items than 465 466 1192 and 1194

This is not development. Remember everyone, post questions in general section, not development!
Thank you,

3g?

sorry for the noob question, i posted this in the non-cdma hero sub-forum (mods please delete other thread) but i tried to search for this question so sorry ahead of time.
does the cdma hero have 3g and if so how do i use it?
3g as in the data service?
sprints 3g is called EvDo, and by default its always on..
yes the Sprint version has 3G if you are in an area that has 3G service. Its not really called "3G" by sprint it's EVDO REV.A
You dont have to do anything special to use it unless you have it turned off. Do you see a 1X or EV in the notification bar?
thanks for the reply. again sorry for the question. yes i have the 1x or Ev
just another tidbit 3g stands for third generation

changing your signal for better or worse...

what would be the best i guess service? you should use wcdma gsm cdma on this phone? if you wanna pick your signal you can get into the secret menu by going to your dialer and putting *#*#4636#*#* tell me what you guys think about this...
What?
I don't...
What?
This is a GSM phone, changing it to anything else might just brick it.
*Maybe posting those test codes was a bad idea.
*#*#4636#*#* and phone information won't change anything. AT ALL.

Correct my n1 could lock on wcdma through that window but for some reason the vibrant won't lock onto it..... but the vibrant holds a betyer 3g signal than my n1 did...
i noticed where my MyTouch 3G had a "wcdma preferred" selection, this one has "WCDMA only", or "GSM/CDMA PRL"
mine came default set to the "GSM/CDMA PRL" and i changed to WCDMA only
connection or download speed seemed to pick up some
i don't think you're going to brick your phone changing that selection - if it doesn't show an improvement, or if you're in a 2g coverage area, i presume it will drop your svc, but don't know why you can't just reselect the default setting

This is just wrong information. This is a GSM/WCDMA phone. 2G/Edge is GSM technology where 3G/UMTS is WCDMA technology. I force my phone back and fourth all the time for network testing.
P.S. I'm a field tech for TMO.

I dont have my vibrant yet, on its way. So your saying that when you enter the phone info page WCDMA Only is not longer an option in the drop down menu? Or is it grayed out?

If you can, will you post on here if you hear any rumblings of an OTA to fix:
GPS reception issues
The Totally Broken Compass
General 3G Reception problems
Please?
Or, hey, if you can confirm if the issues at hand are software or hardware-related. That would do it for me.

Its still they're just switching it don't lock it on wcdma only like the n1....
Itll still switch to edge... Just doesnt do anything.

Well, if I want to keep my job I'm not supposed to post privileged information but I will say this, most issues wont be acknowledged until a specific amount of complaints are called in. In bold words, if no one complains to T-Mobile directly (not on a forum) they wont fix anything. That's just Business 101. Sorry I wish I could be more help.
As for if they are software or hardware, I do not know that. As the phone has only been out for a week, there has been no information from within about any issues. Again, sorry!

My 3G reception has been fine considering T-Mobile's 3G tower deployment and with how my old phone behaved, but anyway it does appear to be a Samsung thing. The -dBm readout under the Android menu system is completely wrong.
I too have noticed that making changes in the *#*#4636#*#* menu to the band selection does not stay. As soon as you go back into this menu, the setting is reverted back to GSM/CDMA auto (PRL), no matter what I set it to. I have noticed that this setting will stick, however, on my N1. The only differences I can see between the Vibrant and my N1 are that the Vibrant is 2.1, and the N1 is 2.2.
Anyone have any ideas as to why this setting doesn't stay?

Do anyone have the latest(or close) Verison PRL 52078????

I googled and can't find a download for verizon 2010 PRLs. Anyone have a link or can rip it from their phone??

This is the Sprint Evo forum. Maybe try a Verizon forum?
I was thinking someone here already had it ripped out of a verizon phone for their use on the Evo too
HERE are a few Verizon PRL's I keep around. There is a 51926 in there, I think from June or July of this year. Also some 65 series PRL's, but I haven't used any of them. I can verify that at least in Vancouver, WA I get great voice and 3G signal with the 51 series PRL's, cant really tell the difference between them, 518, 516, 517, 519, all good for me. Roaming triangle taunts me the whole time though,
Also, link in my sig for some other PRL's for the VZW 3G hack.

Thanks but i've tried 25 roams through out the month with altel/verizon and I always get 1x with 1 BAR. the only difference is some PRLs show the roam sign and others don't. This one even gave me the Roaming symbol.....What could the problem be????
I really don't know what the issue could be. I know that all the PRL's I linked will roam on 3G, so ???

Well they jump back and forth from Evd and Evdo_A when I sit the phone with 1 bar. But if I try to use the phone it jumps back down to 1xrrt with 1 or 2 bars at times. I'm kind of new to the hacking scene but I think everyone thing is good on my end. Unless there are other things you suppose to do after changing your PRL?
I'm no hacker myself, so at this point I don't know what else to look at.
Whenever I run any of these PRL's, I always have my network set to Sprint only, I turn off data roaming and make sure always on mobile data is enabled. But, even at the worst, I get intermittent data loss, but never get anything other then 3g. Have you tried the 00001 and 01337 prl's from the roam hack thread?
For me, on CM6.1, if I run any of the verizon PRL's, and select Sprint Only in the wireless networks menu, I roam on VZW 3G. If I switch to Affiliated Networks setting, I will drop all signal cause it gets confused I guess. If I change back to a Sprint PRL, and Affiliated Networks, I get good voice signal, but show 1x for data. As soon as I put it back to Sprint only, my data returns to 3g.
On any new froyo sense rom, it's almost impossible to tell. A bug that seems like it may be intentional has popped up. My phone will not show 1x, but only 3g. Even when I'm on a sprint prl, and confirmed to be roaming, which would be 1x, It still shows 3g. I dug into the rom, and the icons are there, they just don't show up on a lot of sense rom's
How are you able to tell what evdo ur on? Are you on an Evo?

Theres a app called Cellumap and Phonestatus in the marketplace. It tells you the network your phone is on and cellular provider.
I'm using the sprint lovers CUSTOM rom. I guess I'll switch to cm6 custom rom like you are using and set it up like you mentioned. so I'll give this a try tommorow(sunday) and report back. but I think it's just the RURAL area I live in but then again Verizon has full coverage according to their map...
yeah, probably just ur area. You should call Verizon and tell them about the issue
You could say something like, "hey, I'm trying to use your expanded 3g service for free, but all I get is 1x. Can you give me an ETA as to when this will be fixed?" That would be fun!
I'll give those apps a try on my end and see what I get.
Well, I'm getting EVDO rev a on most of these. Provider shows digital roaming but still says Sprint. Confirmed speed tests at just under 1mbs and dialing a number without area code sends me to Verizon error message.
That is with the 51 and 41 PRL's.
Hey... This thing makes phone calls too!

Aw great for you ... well I'm installing this cyanogenmod6.1 custom rom and see what it does on a different rom I guess. If not I don't know what else I could, probably no roaming agreement with Verizon(altell had my area covered before Verizon bought them so Verizon really never had towers here....)
Ah, so that's why you were looking for the newest PRL. I would think you could get it to work with the right PRL.
Hey... This thing makes phone calls too!

Sprint EVO and other towers?

Ok here's the deal, I have a sprint evo running cyanogen blah whatever. What got my curiosity pumping was that I had this question in my head for quite a while and haven't been able to research anything regarding it.
Ok lets cut to the chase. My evo is obviously sprint oriented, but could there be any way possible tobmake it pick up other towers such as T-Mobile or AT&T, meaning as in their 3G speed, why do I ask this?
Where I'm currently located is a place where Sprint isn't really "Reliable" per say, in fact, we don't actually have 4G towers (WiMax). And I know other companies don't have it either but I'm sure their 3G is the same, I just want to know if there's a way to tweak the phone to accept such signal because where I'm at, Sprint's 3G is terribly unstable and other carriers have it running smoothly.
I think it has something to do with PRL?
Cyanogen
That won't be possible sorry because Sprint is CDMA, while AT&T/T-Mobile is GSM using a different technology and different frequency. You can how though use the Verizon PRL to get faster 3G speeds.
Ok if that's the case, I'm located in Puerto Rico, For some funny reason Verizon has been renamed "Claro". Now if I was to try to find out their PRL, how can I achieve that?
Cyanogen

I'm not sure if the same Verizon PRL that we use here in the states will work but seeing as it is still Verizon, give the PRL file below a try.
http://dana.ucc.nau.edu/add46/00001.prl
You'll have to be on a sense based ROM to upload it to your device.
"Dial ##775#. Enter your MSL into the password box that appears >> hit OK >> tap on the "Update PRL" button. Make sure "All Folders" and "Type: prl files" are selected. You should see the downloaded PRL (00001.prl) on the list; Select the PRL >> Press Menu >> Commit."
Follow the steps above to successfully flash a PRL to your device. If you don't know your MSL code just download MSL reader from the android market (note your device must be rooted).

[Q] 3G/4G or WCDMA/LTE Only

Is there anyway to get 3G and 4G only?
My question is general and i ask in name of both TouchWiz (preferably) and AOSP roms, as i havent had the option to get rid of GSM in none of them.
greets
What do you mean?
Limiting mobile network mode to 3G/4G only, meaning no GSM on it.
I know im dislectic, but i was as clear as it can get.
Anyone?

IF you have a GMS phone and on a GMS network, then that's the only signal you'll receive.
If you're on the wrong forum and/or down-load the wrong rom that'll have an effect also.
There are certain modes under Mobile Networks, many Custom ROMs feature hidden options i.e such as LTE Mode Only. What i am after is for my data never to drop on 2G. I want it strictly at 3G/4G mode only

Really? Then you get no signal if there was no 2g available. That's why no one supports your ?. If you set to lte then it will keep connecting to it if there is lte, if not it ?s to 3g and so on till 2g.
Search for an app to force lte only. If there is one, never searched.

LTE is 4g only, and I would suppose it also depends on your area and modem

Then how do I get ? when I have it set to lte, but my carrier doesn't even have lte where I live? Because it goes directly to 3g or 2g. As far as I know it doesn't stuck with lte if there is no lte.

Wow, idea, is that what you think this is, an idea? Why would someone post an idea in the, let me cite, "Q&A, Help & Troubleshooting" section?
Dude, im after a solution or a workaround for an issue, and the issue does not matter to the world as long as the question is clear enough.
Your theory is incorrect as there is WCDMA mode only, which is absolutely compatible with GSM networks. The point is to never drop on 2G protocols. If you want details, ill throw tons of them, im a network engineer and i can show you anything you need from the tower perspective, my question is from the phone perspective, and that's all.
Some carriers have strict or stupid band jumps, meaning the towers are configured incorrectly to change the transmission mode (i.e you get H+ when the signal is good), so to avoid a carriers stupid mistake, i wanna limit my handset to reject 2G connections (GPRS, EDGE).
Belittling is not an option, i'm dyslectic and i try my best to make my words as less personal as possible, so please next time respond with the intention to answer the question asked and not the one you understood.

Haha ? engineering and can't find a solution. Then there is no solution.
I really don't see the big deal here. A fellow XDA'er has a legitimate question on how to force or is there a way to force 3G or 4G/LTE. I too would like to know if there's a way to only force the phone to use LTE.
LTE Mode only bas been around for quite some time, so has WCDMA (3G). In fact, as you can see on the screenshot i attached a page behind, the developers of the custom Rom have made the feature available. It seems the solution is there but just not as a choice.
Generally, i've been disappointed with this section, even though i myself have critisized people for asking questions in irelevant places, this section remains highly ignored. It seems only power-users will pop around once in a while where they accidentally read a question that may've been a problem for them in the past (myself included), or a troll who thinks belittling will get them somewhere, unfortunatelly.
