[MOD] PRL Write Enabler for Sprint Galaxy S4 [MDC][MDL][MJA]

[ChadH42]

First off this work is based on Digiblur's PRL Write Enabler from the Sprint Galaxy S3 forum. I simply modified it & packaged it for our Sprint Galaxy S4 devices.

Here is the original S3 post that this was found in... http://forum.xda-developers.com/showthread.php?t=2159054

Also, post #8 below provides additional info.

I tested it by flashing with TWRP and it worked on my stock, rooted S4 with the MDC and MDL releases.

If you're on a stock rooted Rom and not using TWRP, you can just copy the HiddenMenu.apk from inside the zip file downloaded into /system/app/ and overwrite the one that's there. (You'll need a root enabled file browser to do this of course).

Thanks to Unknownforce here is a version for MJA...

Enjoy!!

This certainly will save me from having to use CDMA WS to switch like I just did yesterday. 55014 was not working well for me in my market so I switched back to 25014.

You mean the install of the zip?

If so, you can pull the APK out of the zip and replace HiddenMenu.apk in the system folder (make a backup first). You may want to also set the permissions to rw-r-r after replacing the system app. Reboot, then you should be good to go.

@ChadH42,

I know it seems like I'm harping on you but I'm really not..

You need to update the OP on - 1. What is this? 2. What does this do? 3. Why is this in the Development Section.. ?

A good OP leads to less questions.. Development Sections aren't for information. That would be considered a Discussion Thread that belongs in General.

Let's keep the Dev section clean from the start.

My suggestion - Edit the OP on the What's/Why's?/How To's and you won't get posts like mine.

To the OP, updated your title as [WIP], and I suggest you provided additional information so that folks aren't bricking their new devices.

I will check in, if you need anything, let me know.

What this MOD does (in case the OP takes a little while to chime in)

What this MOD does is modifies our ##DATA# (select View) menu to allow for the PRL Write option to appear and function. With this menu option, the user can change their PRL on the fly from the device itself by placing a copy of the desired PRL in the root directory of Internal Storage and name it "test.prl" (no quotes), dial ##DATA# (choose View), tap Write PRL, tap the sub-menu option Write PRL ---wait--- and then the device reboots with the test.prl PRL applied upon reboot. Not every PRL works and sometimes it takes a couple of tries.

A tip for multiple PRL options is to, of course, keep a folder of the PRLs you like and keep them labeled in there. Copy the desired PRL to proper place as needed and just remember to rename the copy to "test.prl". Switch back and forth as you please. I hope this helps clear some confusion and helps some find purpose with the MOD like I have.

For a clear set of instructions that I did not want to just copy verbatim, check the link below. Also, if you are having issues with the zip not installing in CWM, just extract the APK from the ZIP (inside the system/app folder), use Root Explorer or your favorite root-access file explorer to place the APK in the APP folder, apply the proper permissions and reboot.

So I unzipped the file, replaced the hidden menu original apk with the new one, then set permissions, rebooted, then tried ##3282# and the view and edit options do not appear.. .. It just blanks out the items I just entered

Did you clear Cache when you rebooted?

What ROM are you using?

I just tried this mod with the Force ROM and it did the same thing (blank options). The only thing I can think of is that it works with the odex version of the stock ROM so maybe its a problem with deodex ROMs of which Force is one.

 

[jayjay7411]

O okay. Its currently not a necessary thing for me at the moment, just nice for when I travel to Alabama. Hopefully later on someone gets it working on deodex.

I am actually running it on the Rooted Stock DeOdexed ROM. So I don't think it is an Odex/DeOdex issue...might be a Force ROM issue.

Also, moot point for Force ROM (1.0+) anyway because the PRL Write mod is already included with that.

 

[Sterist]

I'm also having this problem and I'm pretty sure it was working this morning. I haven't flashed anything since then.

edit-- I tried:

1. wiping both cache's
2. killing background process "OIThiddenmenu"

neither fixed it.

 

[ChadH42]

I reinstalled the stock odex ROM and flashed this again and it worked.

Just an FYI, OP, I get Error Status 6 when trying to flash this via recovery, which indicates one of two things. Either the format of the file is incorrect or there is a syntax error. The syntax looks fine, but opening in basic Notepad shouldn't "look pretty" like it currently does. So it's likely it was edited with a non-Unix-compatible text editor like Notepad or MS-Word...

To make modifications to an updater-script (or just about any Android/Linux files like this) you need something like Notepad++ or gVim.

Anyways, I did a quick test with this, and it does in fact not work on my ROM as it is, but I see why it's failing, but I don't know what exactly it's trying to reference yet. (It fails with an id number instead of a name, so I'll have to de-compile some things to find it.)

I'm not sure it's a ROM issue or a MOD issue yet. (meaning it might have to be updated for each custom ROM, depending on how they are configured) But I'll track it down and update when I can.

Thanks for all your help here..

I had the error status 6 problem in the beginning and thought I fixed it. You are correct that I used MS WordPad to edit the files.

I think TWRP can read the non Unix type characters, which is why it works on a different recovery.

I'm hoping it's a mod issue and I can just modify the mod to work universally regardless of the rom. But we'll see.
