My kit includes a GB ROM that gets restored as a nandroid backup from recovery. Just follow the instructions in the OP for installation and you will have everything needed to change your PRL from the phone without a PC.

Make sure to do a nandroid backup of your current ROM before restoring the one in the kit so you can return to it later.

I am unable to connect to 3g. only 1x. One attempt to fix the problem was to put on the same version prl that my wifes evo 3d has.

this did not fix the problem. still stuck on 1x. cannot figure it out. it just takes a long time to connect, and when it does its 1x
[HTC EVO 3D] ramjet73:
The PRL can only increase signal strength by allowing connection to additional towers. If it doesn't improve connectivity for you then it's probably best to stay with the one that is downloaded from the system updates section of settings.

the issue was that the 5x versions went screwy and people were forced on 1x. this was some time ago. i did not have the 5x version i had 6x. but im trying to get everything to be the same as my wifes phone. i knew this was a longshot. but was worth doing.

s-off success finally...

I finally had success with s-off and decided to try testing a few PRL files..

I downloaded QADPUK and followed ramjets instructions for updating my PRL via 4ext..

I tried 3 or 4 times but seemed like it was getting stuck on the HTC boot screen after the install and reboot.

Well,,I thought, that didn't work......so I decided to try boot manager pro and thoroughly screwed up my phone...

After hours of tinkering I got my old ROM back but don't know if I wanna try that again.

Any thoughts ?

[HTC EVO 3D] ramjet73:
You can't boot GB ROM's with the 1.58 hboot. They require an hboot version lower than 1.57 just like the AOSP based ROM's. I'll add an advisory to the OP.

That's probably the cause of your problems trying to use Boot Manager as well, but it should't screw up your phone. Flashing or restoring an ICS Sense based ROM should get you back to where you started.

[HTC EVO 3D] gunfromsako:
I'm gonna drop this here for you to play with...

It seems to be that sprint got tricky with their epst.apk in ics and jb. With a simple build prop edit the ##778# code becomes available and on device prl changing is available without a hitch. I've only tested on the Rom above but I'm getting ready to flash a 3.6 Rom and try it out, but I'm assuming with the proper epst.apk its possible on any sense Rom.

The build prop edit:

ro.build.type user

Change to

ro.build.type dev

Reboot and try. It's basically the same procedure as with ##775# .

Hope this helps! Thanks for all your helpful threads and ninja links ramjet.

And thanks to rulingczar for pointing me in the right direction.

Edit: yep it works for 3.6 and if you guys ever get a jb port it should still work :D
[HTC EVO 3D] ramjet73:
Wow!

That would be great if it works with any Sense based ROM.

I'll give it a try on nega's BluROM right now.

Edit: The ##PRL# code didn't work on BluROM even though the ##DATA# code did. Made sure the build.prop parameter changed but maybe it requires a specific version of epst.apk?

[HTC EVO 3D] gunfromsako:

[HTC EVO 3D] ramjet73:
Thanks for sharing this.

I'll still leave this guide active since users running AOSP based ROM's might find it easier than flashing back to a Sense ICS ROM. The de-Sensed GB ROM I'm using is pretty small for a Sense ROM so it's nandroid backup takes less space on an SD card than an ICS Sense 3.6 ROM would, but it's nice to know that it can be done without changing ROM's for anyone that uses a Sense ICS based ROM as their daily driver.

A couple questions, is this Sprint only? Or if VM users can do, I have a tower that's pretty close, decent 4g signal, would I be better off just sticking with my prl?
[HTC EVO 3D] ramjet73:
VM users can use this guide to change their PRL but I'm not sure how effective that will be. One of the main advantages that I see in changing it is improvements in roaming options like the data roaming allowed with the corporate PRL, but VM doesn't allow that anyway. I'm not sure it will make much of a difference for your connections since that varies drastically by location and that's why I've included the apps to test it yourself.

My signal at work has been pitiful last few months (1x ie, 100k) so I am playing around with some of the Sprint corporate prl's to see if I can keep a better signal. Thanks for the heads up that the epst works in Negaman's Negalite Blue rom. All I had to get was the prl zip from the op.

Last year, I was following an Evo3D thread about the different prl's but never did anything with the info. I am pretty sure it walked you through how to backup a current prl to sdcard. I want to locate it so a backup of the 21094 can be done.

[HTC EVO 3D] ramjet73:
I think extracting the PRL may require a program like QPST or CDMA workshop and the diagnostic drivers but I just tested using the epst.apk on MeanROM ICS 2.6 with the "ro.build.type dev" mod and was able to downgrade from the corporate (61092) PRL I was using to the 21092 version in this kit and then upgrade to 21095 by doing the online PRL update. It wouldn't update when the 61092 PRL was installed.

My understanding is that the current PRL may vary by location so I'm not sure everyone would be able to upgrade from 21092 to 21095 but it worked for me.

Edit: There are some PRL information links in this post and I think post #3 of the first thread linked may contain the info you are looking for.

ramjet73
[HTC EVO 3D] mpgrimm2:
I was thinking I could just switch over to 21092 and update it to get back when needed. Thanks for the extra links and confirmation. I'm trying out 12126 now since one of the info threads linked in your op show it as Corporate/Network Vision vs just corporate. The other info link shows it as corporate with no LTE/low priority 800smr which is most similar to the residential 21xxx PRLs (default).

Desperate times when I've gotta play with PRLs to get 'decent' 3g. Still no Sprint 4g at all in this part of Va. Even considered breaking contract ($450) to switch carriers this week.

Price comparison for 3 smartphones w/unlimited data, texts & 1000 minutes (24 months)...

- Sprint. @ $170/month (no 4g here)

- US Cellular @ $230/month ( unlimited 4g here)

$300 visa gift card to switch & $100 off Samsung Galaxy phones thru March.

- T-Mobile @ $210/month (unlimited 4g here)

- Verizon has 4g, but not unlimited anymore.

$40 - $60 extra per month adds up quick so I will see what I can squeeze outta sprint. Running out of patience with them more and more.

Hard to say.

Some VM users that have switched PRL's claim it has made a difference but the only way to find out is to try it and test. There's a popular thread in an Evo V forum on another website that includes flashing the Sprint 60690 PRL instead of the VM default 61009 PRL using QPST and the diagnostic drivers but it's listed as optional and most users haven't seen much difference with the change.

Confused about non-Sense based PRL's

I am confused about how PRLs work in custom ROMs. I installed the Wild for the Night CM 10.1 a few months ago. I gradually noticed that I was getting lousy data speeds at times, sometimes worse than 300 kbps. I eventually noticed that it was especially true at work. I did not originally connect it to the ROM because we had just moved to a different floor. I thought it might be some combination of building construction or height aspect of that floor causing the problem. So yesterday I decided to load the stock ICS Sense based InbREDed 5.5 ROM. All of sudden my data speeds went over 2,000 kbps. Could it be because of the InbREDed 5.5 has current PRLs due to it be based on stock Sense? Do non-stock non-Sense based ROMs such as Wild for the Night CM 10.1 have PRLs included with them? I am confused as to how it could or what version it would have. Or is maybe just some issue with the CM 10.1 ROM itself? (NOTE: As a new user I don't have permission to post any questions on the Wild for the Night thread).

I really want to go to back to CM 10.1 but I don't want to go back down to useless data speeds. I wiped my system and data partitions and did a fresh install of the latest version (5/1/13) of Wild for the Night. I have read through this thread and am confused as to what to do next with the PRL. If I run the kit and install the ROM to get the new PRL, isn't it going to overwrite my CM10.1 install? If I backup the CM10.1, then install the app to get the PRL and then restore the CM10.1... isn't going to overwrite the new PRL I just got?

Thanks,

Bob-C :confused:
[HTC EVO 3D] #WB:
if you flash a PRL on a Sense ROM, that PRL will remain if you flash a AOSP ROM.
[HTC EVO 3D] gunfromsako:
Hi Bob :D

Flashing a rom will not change your prl so no worries there. Totally different parts of the phone.

As for the speed increase when flashing back to sense I'm not quite sure. The only thing that may of increased it would be a profile update. I would do a clean install of cm10.1 to compare data speeds. After being on aosp for so long I'll flash back to sense to do a profile update when I notice slow data speeds.

Do you go in and out of service a lot?
[HTC EVO 3D] Bob-C:
Where is the PRL stored? Is it in the /system partition?

Where the PRL is stored is a big source of confusion for me. I read the link to the alternate method Ramjet posted and it says the following:

Step 2 - Install a root explorer of some kind (i.e. - Root Exolorer, ES file manager) and make sure you're in "root" mode and that your system directories are mounted as "rewritable"

Step 3 - Go to where you had downloaded the older epst.apk file and the 21081.zip file from that zip file, extract the 21081.prl file to the root of your sdcard

Step 4 - Copy the old epst.apk file you had downloaded and then navigate to your system/app/ directory

Step 5 - In the aforementioned directory, there should already be an epst.apk there. Rename that file to "epst.apk1"

Step 6 - Now take the epst.apk you had copied and paste it into the directory you're in which should still be the system/app/ directory.

So I take that as meaning the epst.apk file contains the PRL and is stored in /system partition of the phone. When I use 4EXT to do backup and recovery, I notice that it backs up and restores the /system and /data partitions. I am assuming the restore operation completely wipes and replaces the /system partition.

So right now I have the Wild for the Night CM10.1 ROM installed. Ramjet's instructions say:

1. Download the kit from here

2. Copy it to the /sdcard/clockworkmod/backup directory

3. Unzip the QADPUK-1.0 directory to that location

4. Restore the backup with 4EXT or CWM recovery

5. Boot the ROM (pic #1)

Won't step 4 wipe and replace the Wild for the Night CM10,1 ROM currently in the /system partition with the QADPUK-1.0 ROM? If I backup up my CM10.1 ROM first through EXT, do the procedure above and then restore the CM10.1 ROM from 4EXT, won't the restore wipe and overwrite the /system partition that QADPUK-1.0 just wrote the new epst.apk file to?:eek:

[Guide] EPST and programming your phone, no data, stuck on 1x help, tips and tricks

Check out my thread and I suggest searching for "prl" on xda. A lot of your questions can be answered.

PRL is not stored on any partition related to a rom. EPST is just an apk to allow on device NAM changes. The kit is kinda out dated as ramjet73 will tell you.

Edit: I'm late for school or i would explain better. Maybe the jet of ram will chime in :silly:

Edit 2: the kit isn't outdated just isn't necessary. All you need to change a prl is a sense rom...
[HTC EVO 3D] Bob-C:
I understand now - Thx!

I read through your guide and it really helped me understand. I just loaded the Sense ROM and did a PRL update from the Settings menu. The speeds look good at my house but the real test will be what they look like when I get to work. It is just sitting at my desk where there was a big difference between the inbRed and CM10.1 ROMs. If the speed sucks I will try the methods you outlined in the FAQ Section of your guide. Will let you know what happens. Thanks for all the help. Hope you had a good day at school!!:laugh:
[HTC EVO 3D] ramjet73:
The PRL is part of the carrier settings, just like the 3G/4G data settings, and is only used for CDMA based phones. I don't think it is stored in a partition per se, but I'm not really sure about that.

This kit is not outdated if you are running an AOSP based ROM since it's just as easy to load a GB Sense ROM as an ICS Sense ROM and this one has all the utilities and PRL's integrated. An AOSP user can also set diagnostic mode and use QPST but in my opinion that's more complicated than flashing a Sense ROM. Even if you are running an ICS Sense ROM you may need to change the build.prop file if the developer hasn't done that already.

ramjet73
[HTC EVO 3D] gunfromsako:
I hope you didn't take any offense to my previous post. It came out wrong, and I should of edited it out. This is great for aosp users! I know QPST can be a pain sometimes... DFS is awesome :)

Like you said the prl lives happily with all your 1X/3g/4g/data settings in NAM. Which I belive is "cdma_record" pictured below but I could be wrong.

*this is for Jewel not shooter.

I did a lot of googling last night trying to figure out which partition (if any) the NAM on a phone is located but came up empty. I'm going to keep searching when I have more time (finals week) and see what I can deduce.

[HTC EVO 3D] TheLyon32:
As a new user I have encountered this issue and I used QPST but lots of reading and searching revealed a much more simple solution. Its choosing the correct ROM with a modified Build.Prop file like RamJet mentioned.

Using the NegaLite-BluRom all you have to do is:

1. Download your assortment of PRL's to your SD card.

Plenty links available in this forum

2. From the Dialer input "##778" which opens EPST

3. Select edit mode and enter your MSL code

(download MSL reader app from play store if you don't have it already)

4. Select PRL-> Update PRL. The PRL files will be detected. Select the one you

want then press ok.

5. Select "Menu" in top right corner and "Commit Modifications"

And thats It.

You can test speeds of different PRL's in various locations without PC and when you find the one you like, flash the AOSP ROM you prefer and settings will remain intact.

Before doing this you should make sure you have a backup copy of your current PRL(or latest available when you "update PRL" in settings).

You can't update it on AOSP ROMS but you can on the NegaLite ROM.

Two ways I'm aware of to back up your PRL:

1. find it via search and save to your SD card. This is the easiest method

2. Extract it yourself with QPST. Much more time and effort but very doable.
[HTC EVO 3D] jcfunk:
The PRL is in the radio_config partition, for the 3D that's partition 19. No way to really edit it without messing up stuff. Best bets to use epst or qpst.
