[Q] possible to enable roam only? - HTC EVO 3D

I have a unrooted Evo3D. Sprint is in the middle of there network vision upgrades in my area and right now reception is so poor I can't make a simple call or txt while I am at work. Is there a setting or some app that I can force it to roaming only instead of being stuck on the Sprint tower that is down until they finish the upgrades? Hopefully something that I can do without rooting or downloading different PRLs when I want to switch back and forth.

Flash verizon PRL file will solve the problem. I don't have that file on hand now. But google you will find it.

Yes I could but it would be a pain to flash the Verizon PRL when I get to work and then flash back to the Sprint when I leave to go home.

Roam Control should do what you want. Note that there is a fix in the most recent version for an unrooted Evo 3D. It costs $4 but that might be worth it in your situation.
If you decide to root your phone, MeanROM ICS 2.6 has a "roam only" option built-in.

Works great! Just takes a minute for it to switch over.

[Q] Lost my hybrid PRL after root...

I live in the Tampa Bay area which is generally an old Alltel stomping ground, and when I got my TB, I had to have VZ push the hybrid PRL (13006) to my phone to get any decent signal. I rooted last night (successfully, thanks to your guides and posts) only to find that my PRL had been reset to 15027. Is there any way for me to restore this setting, or am I going to have to call VZ tech support and get them to pull the hybrid PRL for my phone again? And ... more importantly, will I have to do this every time I flash a new ROM, or is there a way for me to backup/restore this information? Any help you can give me will be much appreciated.

These phones don't use PRLs in the classic sense. They receive the roaming list on the fly so whatever PRL it says you have should be the one you need. What's more, the method used by LTE isn't at all like cdma. I've been all over hell and back with mine. It kinda sucks going to a new area because it can take up to an hour for it to find signal and data service sometimes. Took mine most of an hour to find data when I got the thing at the store. I'm also not sure a ROM would change the PRL since that's radio stuff. Most likely if it changed, the phone did it by itself.
If you can get your hands on the prl file these links should help out. I was able to get a cricket droid inc back onto verizon by using these prl files.

What Radio can I flash?

I have terrible reception on my phone.
I want to flash a new radio but I'm not sure which one to flash
I'm running CM7 and switch between that and MIUI roms.
I don't want to flash the wrong one. Can someone guide me in the right direction??
Thank you.
You can look here for radios. But you should read as much as possible before flashing a radio.
http://forum.xda-developers.com/showthread.php?t=1193101
Also try updating your profile and prl and see if that helps. Or try a data reset.
Hope this helps

correct. I suppose it is possible, but no one has figured it out yet.
Agreed.. I don't think us HBOOT 1.5 guys can flash radios yet. Another thing to try, if you haven't already, would be to install the Open Signal app. It'll give you your radio signal strength in dbm and even plot your current tower's position on a map. Great app although it is a bit of a resource hog with all of its radio polling.

You might do better to flash a PRL. Safer and can lead to better signal without even changing the radio. Lots of people on here think they know it all and will tell you the PRL only affects roaming signal, but dont listen to them as they probably havnt tried changing PRLs and have no idea what they are talking about. Flashing PRL 00001 fixed my signal at my apartment by connecting me to the Verizon towers without being on Roaming mode. And 01337 gave me a little bit better signal in my apartment over 00001, even though I dont appear to be connected to Verizon towers anymore. Lots of people really like 11115 and I am going to try that next as it should be the best for signal since it uses both Sprint and Verizon towers equally and gives full 3G on either company's towers.
To flash a PRL you will need to be on a Sense ROM that has the extended EPST.apk installed. Put a PRL you want on your SD card, dial ##775# and put in your MSL code. From there you just select which PRL you want, press menu and then commit changes. Reboot and your good to go.

Actually my friend, I appreciate you trying to help me but in this case I will help you out.
I did tho PRL trick a year ago on my regular Evo. About 4 months later, I received a letter from Sprint stating that "even thou roaming is free on sprint, due to the overage roaming that I have used, they will terminate my services if my habits don't change in a month." Well I tried my best to change them but i guess they weren't satisfied and terminated my services. I had to call and beg and go on a 90 probation period where if I went over the limit by even 1min/mb, they you disconnect me. So I'll never do prl again. Instead, I downloaded this app called Roam Control and only use it when i'm waiting for an important phone call.
Radio on the other hand is a signal from Sprint and will not put you into roaming.
Aren't the radios loaded in the RUU? Can't you just run that and then unlock again with htcdev?

Well, I am not entirely certain that the radio is loaded into an RUU. Someone recently told me that the RUU would not change the radio version of your phone.
The thing is,the Hboot 1.5 folks cant revert to a pre HBoot 1.5 via RUU anyhow, so no one can try it. And while there are two RUU's available to Hboot 1.5 people. (2.08.651.2 & 2.08.651.3) They both have the same radio. So I can't run one over the other to compare radio versions before and after the RUU. Once a new update gets pushed with a different radio version, I could run the RUU to see if the radio flashes with it.
The one way I would think it is possible to switch radios is to re-lock the device, run an RUU to unroot, then accept an OTA to get an updated radio. Once you take the new radio via OTA, you would use HTC unlock again to unlock, flash a custom recovery, flash the SU binary and voila.
This of course is contingent that HTC doesnt backtrack on their unlocking promise. If you took an OTA and the new update is unable to be unlocked via HTC, you would be screwed. So we would want to make sure that they dont push an update that they wont support with the HTCDev tool. And of course the other flaw to this is that you can only "upgrade" the radio and never revert to a prior radio that you may have liked better.

Enigma, Can you tell me if Sprint charged you a ETF when they initially cancelled your service? I'm kind of looking for a way out of my contract and was hoping this might actually do it.

I guess it was this sentence which led me to believe that.
I didnt ever say that though, that was some other guy. I cancelled my service by myself about 7 months after this post because I moved to Verizon since I was using their network all the time anyway. Sprint service is just too ****ty in my area. And not just cell/data coverage either, but text problems on their network were the worst I have ever seen. But I never had any problems from Sprint about data usage or things like that. The person who said Sprint contacted them about roaming usage must have been using multiple gigabytes of data each month, I normally only use 500MB-1GB at most unless I am tethering something.

[Q] CM9 3g roam speeds?

I see that you can now, in CM9, force roaming but i only seem to get 1x speeds. I'm not sure if thats just because im in a low coverage area for verizon? I saw screenshots Joker posted of him getting 1mb+ on verizons network with CM9. Anyone know if he was running a new PRL or if it was just CM9 that allowed this? Huge thanks to Joker and all involved with their amazing work with the Photon and CM9!
Could be area and how close to the connected tower. Wish I could remember the Web page but you could with the connection info see the tower you were connected to look at the maps and see how far it was from you..
I used to do this all the time with my old VZW air card.. It was interesting because you may be a closer antennae or tower but the device would insist on the further of the two. The cool thing was being able to try forcing it to one over the other..
Not sure about cm9 but there has to be a way to bring up the connection info.. DBm, tower number, etc.. Could be some pound code to access it?
This is a standard function of CM. I haven't yet tried the CM9 alphas, but on my evo I was using CM7 and put my network onto automatic all the time at work so I could pick up a decent VZW signale, instead of my crap Sprint one in the building. Sometimes I would get great speeds, sometimes not.
I ended up just flashing a Sprint "business" PRL that allows 3g roaming onto Verizon, they *supposedly* only allow 1x roaming for normal users. I tried putting network to auto on CM7 on my Photon and it didnt do anything, however since ive flashed to CM9 on Photon it switches right over to Verizon's tower and i now, due to the new PRL, jump right to 3g Verizon(where there is 3g, obviously) And to tell what cell tower i'm on, I use an app called "OpenSignal" its in the market for free and has done well for me for a while now.
Cool thanks for sharing will have to checkout OpenSignal.

How did you flash the prl? I was on 11115 then flashed to cm7 which gave me the 51083 prl. I can't seem to get cm7 into the right mode to flash the prl. All the posts on the web are for the evo. And those folks have to go back to stock to change the prl. I am stuck with the 1x roaming as well.
This tool allows me to force roam on cm7 but I believe that my prl is limiting me to 1x.

I ended up restoring(via nandroid backup) to a stock blur rom from right after i unlocked/rooted my device and was able to follow THIS guide to get the PRL 01115 to flash to my Photon. Once i flashed PRL i just restored(again via nandroid) back to my CM9 backup. You will need your MSL, if you dont have it just call Sprint and tell them you need to do a data profile reset and need the 6 digit code and they give it out no questions as long as you play dumb and don't call it the MSL. And thanks for reply Joker! But i was out other day with some buddies(who are on verizon) and they were getting good 3g verizon speeds and i forced to roam on verizon and couldn't get over like 16k down(this was before i flashed new PRL). And in Settings - About Phone - Status it showed i was on 1x roaming, even though we were in a great 3g zone for verizon. Idk if that was a fluke or what but now that im on this 0115 business PRL i see flying speeds when force roaming. Cant thank you enough for all the amazing work you've done!
So do a nandroid back to stock and then nandroid back to cm7/9? Where is the prl info located that it would not change with a nandroid restore? I'm going to give of a shot and see how it goes.

It worked!
My stock nandroid would not flash (Error while flashing boot image!) so I wiped and flashed Jokerstockrev1 (nice ROM BTW) in CWM. This enabled me to enter BP tools mode and flash PRL 11115 using QPST. I nandroid'ed back to my CM7 backup and I now get 3g roaming! Not that I need this right now since I am in a Sprint saturated area, but having the option is nice when I travel to remote areas.

**PLEASE DELETE** [DEPRECATED] bar = ucwords

still works for me, but not everyone..please delete
I am admittedly not very well versed in cellular technologies, but I know a few things. When I click on "Select radio band" it gives me a menu with the heading "Set GSM/UTMS band". With the EVO LTE being a CDMA phone, what good would it do to change a GSM setting?
nice find....almost like a roam only hack. When I choose 800 I immediately start roaming, which at work gives me much better signal.
Hmmm...I did this, and I did get much better reception but it also immediately went to roaming. When I went into settings and forced it to use the Sprint network only...all signal was lost.
Not sure I want to force roaming all the time.
Sounds like Verizon's 800 MHz signal has better coverage in your location than Sprint's signal, and you're forcing it to roam (they have reciprocal agreements).
Definitely YMMV, but hey, it should work fine. Note that Sprint has the option of terminating you if your roaming minutes go too high.

To reverse the effects, just press the multi-task button (or redo the first steps) and choose Cellular 1900. That should put you back on Sprint's spectrum.
I'm not suggesting full-time roam, but it does help if you're ever in a low signal area on Sprint..
I immediately reversed it. It's a good trick to know if you're ever in a spotty area and need to force roaming though.

Don't do this! You can't get it to automatically switch between the two after you choose one.
As a part of sprints network vision they are slowly converting their iden network (push to talk) which is on the 800mhz band to a voice band which will soon result in stronger signal and better coverage for voice. So this will be a good tweak in a few months once that is fully carried out but for now it's just going to throw you on verizon if you select 800mhz

Before trying this; if you use Google Wallet, please go RESET it now, and sync all of your data because this will reset your phone back to stock.
Now try a Reverse Logistics
1. From your phone dial pad enter ##786#
2. Select Menu from the top right corner
3. Select Reset
4. Enter your MSL code (you can call sprint to get this or root your phone and use MSL Reader)
The Phone should reboot and clear all data and system. I know you can just do a factory reset but I did the same thing and for some reason the factory reset and stock RUU did not work for me I had to do the ##786# which got rid of the X, but the data would not come back on, but since I got the phone data has been spotty, but the new PRL has fixed that somewhat.. I've bricked about 3 phones since the launch date trying things I know I had no business, but my curiosity has allowed me to find fixes for a lot of problems except for the NFC bricking problem with Wallet (SO PLEASE RESET GOOGLE WALLET BEFORE DOING THIS RESET).........
Good luck and let me know it this gets rid of the No Signal problem from manually switching frequencies.

Oh my, thank you so much for this. Seriously, thank you. I was contemplating returning the EVO for a new one after messing this up. After following your guide, I can not roam on Verizon 3G with 11115 PRL without manually choosing 800Mhz. Thank you!

[HOW TO] Manual PRL update

I'm writing this to try and save you guys some steps. This is a combination of things I've pieced together from several other instructions. Necessary files will be attached as best as I can, links will be provided otherwise.
This should give you 3G on verizon. I seem to get it no problem. However, I am not sure that it will be as fast as the 3G on Sprint, and it will definitely prohibit use of Sprint's LTE network, if you're one of the lucky ducks in the six cities starting up LTE soon.
if you bork your phone, I'm not responsible for that. You do this at your own risk.
things you'll need-
HTC diagnostic drivers
CDMA workshop (demo version is fine)
your MSL
a PRL to push to the device
if you're rooted, you can get your MSL by simply using MSL reader. I got mine from sprint when i was activating my phone.
you can get PRLs from this page. I chose OOOO1, because it's a verizon PRL, but your phone doesn't say roaming all the time. you need the .prl file inside of the zips, not the zips themselves.
turn on android debugging in your settings, and allow sideloading (i've read this is necessary, but i already had it on, so i cannot verify that it won't work if it's off)
Download the htc drivers folder below, and unzip to somewhere.
go into diag mode ##DIAG# on your dialer (that's ##3424#)
plug your phone into your computer (windows 7, i haven't done this on the linux side of my machine yet, so i'm not sure how it all works out there).
open up the device manager
(just start typing 'devices' in the search field, it will pop up. or type 'devices.msc' ) don't use the quotes.
you should see the phone, under 'ports' (so i've read) or modems. wherever it pops up, it should be in yellow, because we haven't installed the diagnostic driver yet!
right click on it, where ever you found it in the devices list.
choose to install/update driver. click 'browse my computer'. click 'let me pick from a list of drivers'. click 'have disk'. click 'browse'. navigate to wherever you put those htc diagnostic drivers, and select the one (64 or 32 bit) for you.
it should then be in the device list as a modem (assuming your phone is still in diagnostic mode). right click on it, select properties. figure out which port it is on (the modem tab)
open up cdma workshop. you should only have to doubleclick the executable file (cdma_workshop.exe) to open it up. this is the demo version they give away freely on their website. this is not a cracked fully functional version. but, it does what you need it to.
set the port to the one you just read out of the device manager. hit 'connect' and then 'read'.
click on the security tab. write your MSL in the field under 'SPC/user lock'. in the drop down menu there, select 'HTC method'. click the little box just to the right of your MSL field until it says 'S'. Click on the SPC button there and hit 'send'. Your phone should now be able to be accessed by CDMA workshop.
Go to the 'Other' tab in CDMA workshop. under PRL, leave it at Universal, NAM1 (I also wrote to NAM2 for some reason. I don't know enough about this to say with perfect accuracy what would be 'most appropriate'. just a warning).
click on the 'write' button. it will bring up a box for you to find and choose the PRL of your choice. hit okay. boom. written.
now, from here, i also changed the preferred radio to the 900mHz band cellular.
those instructions can be read here .
basically, that's *#*#4636#*#*, hit phone info, menu, select radio band. i also changed my preferred radio to include all the network types and switch through them automatically.
i've changed my prl, and radio type, and i'm getting 3g on verizons towers, not showing roaming (although i am roaming, it just doesn't say so because of the modified PRL)
there you go kids.
btw, i did have to reboot my computer twice to get the drivers and the phone and cdma workshop all to place nicely together.
hope that helps someone.

Yes they can, you can view the amount of roaming data used online on sprint.com
People have had their contracts terminated for roaming too much, but on the flip-side, there's people out there who have roamed constantly without a warning letter or anything from sprint. YMMV

dont do it
sprint is clamping down on it
i got a warning call once, and they said i did over 900mb while roaming
yes, sprint knows. i don't care. honestly, if they kicked me off, it's fine with me. i move in two weeks to a part of the country that basically only covered by verizon.
Do it a lot if you wanna get out of your Sprint contract without cancellation fee's.

Use a lot of data while roaming, and I mean gigs of it. Sprint will catch on and kick you off contract. Thats what some people I know did to get out before their 2 years was up.
Did you not catch timothydonahues winky smile lol ?

Btw.does sprint charge for roaming?

Don't think Sprint charges for roaming, but I do this only because I have to. Work related.. I use the OG EVO 4G EPST.apk so I can change PRL on the fly when I need to Verizon 3G.
I'll have to double check but Sprint does throttle/limit roaming 3G to 300MB. At least that's what happened to me. Couldn't get decent Verizon 3G after I went over last month. After billing cycle I was able to get back good roaming speeds.
If you do this don't abuse it..

it depends on your plan, my plan does not charge for it.

Will a verizon LTE PRL give a sprint phone LTE? Can our phone roam on LTE?

Nope. Verizon's LTE network is different than Sprint's. They run on different frequencies.

Will OG EVO 4G EPST.apk work for the EVO 4g lte, if it does would you mind posting a copy?
I followed the instructions you posted and it seems to be working, but I was just wondering how I will know I"m on verizon since the 0001prl file removes the notification and is there an easy way for me to control when I am on sprint or when I'm on verizon?
Thank you very much for all the help, this feature is great if I"m in a bind and need service!
Anyone know if Sprint let's you start another line after getting kicked out? Not that I plan to or anything..

without an EPST.apk that will allow you to manually choose the PRL, you have to use this convoluted method to change to verizon. switching back to sprint only requires you to go into settings>updates>update PRL. it pulls it from the network.

You have 6 months to go back to sprint.

is there a EPST.apk for the EVO 4g LTE?
Hi Guys...
is there a EPST.apk for the EVO 4g LTE, so we don't have to be by a computer to change the PRL?

i tried about 3 different versions, none worked. that is what i tried to do first. i'm not saying there isn't one somewhere that works, i just couldn't find it.
could we use "roam control" app to switch back and forth between verizon prl and sprint? anyone try this
