When I found the Darth Stalker multi-carrier ROM for the Galaxy S4, I was very happy. It works very well, and has allowed me to take my Verizon Galaxy S4 (i545 version) -- that wouldn't work on a US GSM carrier -- and put it on a $60 AT&T "GoPhone" BYOD plan. This saved me about $80 a month since I have 2 phones on the account.
Unfortunately, soon after flashing this ROM, I found out that my WiFi could not be turned on. After some research, I found that there were some modules not included in the ROM that are needed on the i545 variant for WiFi to work properly. I was able to install these easily.
Unfortunately, this ROM will **NOT** work alongside the stock ROM through SafeStrap; it will flash in a ROM slot just fine, but it won't boot at all. This is thanks to the antics of Verizon developers in Verizon's constant attempt to lock their phones to their service. But all is not lost! This just means that you must flash this ROM over the stock ROM.
I have put together the following guide, based on my own experience, that will allow you to properly backup your stock rooted phone completely, properly flash the Darth Stalker ROM over the stock ROM, and make your WiFi work properly. I am using this device & this ROM as my "daily driver", and it works flawlessly.
If, for some reason, things go wrong and you manage to soft-brick your phone, you can re-flash the original MI1 ROM by following the procedures in this thread --> [ http://forum.xda-developers.com/showthread.php?t=2301259 ], which also lists download links for the Odin image file and all tools mentioned. Once your phone is recovered, simply re-root it and install SafeStrap in order to completely restore it to pre-flash condition (right down to the wallpaper) using the nandroid backup i will show you how to create.
INSTRUCTIONS TO PROPERLY FLASH DARTH STALKER v9 ON THE i545 VERIZON/ GALAXY S4:
1. This guide assumes that you have brought your Galaxy S4 up to the I545VRUDMI1 baseband version. If you have upgraded past that, there is no way to do this at the present time.
2. Follow the procedute outlined in the this Forum thread --> [ http://forum.xda-developers.com/showthread.php?t=2487142 ] to "ROOT" your Galaxy S4.
3. Once you have successfully rooted your Galaxy S4, you can now begin to convert your phone over to one of these GSM carriers, and use a much less expensive GoPhone or StraightTalk SIM card.
4. Go here --> [ http://forum.xda-developers.com/devdb/project/dl/?id=991 ] to download SafeStrap custom recovery, version 3.62. Once you have downloaded it, copy it to your phone's SD card.
5. Go here --> [ http://forum.xda-developers.com/showthread.php?t=2292054 ] to download the Darth Stalker ROM that supports multi-carrier operation very well. Once you have downloaded it, copy it to your phone's SD card.
6. Go here --> [ http://forum.xda-developers.com/devdb/project/dl/?id=1342 ] to download the modules that must be added to make WiFi work on the I545 version of the Galaxy S4; the developer did not add them into version 9 of Darth Stalker, but it is easy to do. Once you have downloaded it, copy it to your phone's SD card.
7. On your phone, tap your way to "Settings -> Security -> Unknown Sources", and make sure that it is checked/ enabled.
8. Now that you have all of these ZIP files on your phone's SD card, you have allowed it to install from the SD card, and your phone has been successfully rooted, bring up your phone's file manager.
9. Navigate to your external SD card, and tap on the green shield icon to install SafeStrap. Once it finishes installing, tap "Open", then tap "Install Recovery". Once it is finished, tap the new button for "Reboot Into Recovery" and let your phone reboot into SafeStrap Recovery.
10. Once you are in SafeStrap, tap on "Backup"; make sure that "Data", "Cache" and "System" are all checked, and that the storage location is set for your external SD card (DO NOT PUT THIS BACKUP ON YOUR INTERNAL STORAGE!!!). Then swipe to start the backup. This is referred to as a "nandroid backup" and you can recover your entire phone as it exists at that point from it. Let it work -- it should take around 10-15 minutes.
11. Once you have your backup done, tap "Back" to return to the main menu. You will see, in red at the top of the window, that you are working with the Stock Rom slot -- DO NOT CHANGE IT -- that is what we intend to do.
12. From the main menu, tap "Install", then select your external SD card in the Storage field; then scroll down to "DARTHSTALKER_S4_V9.zip" and tap on it. Swipe the button to begin flashing this ROM.
13. In a few seconds, the Aroma Installer will start up which will allow you to specify what features you want in your ROM. Make sure you follow these "bullet points" from the developer, jovy23 [ http://forum.xda-developers.com/member.php?u=4454815 ] -- it matters!
* Choose The "Full Wipe" Method.
* Choose Any Of The Apps You Want.
* Now Install The Rom Until Its Finished.
* The Aroma Installer Will Then Reboot Your Device.
* Once Rebooted And In The Setup Wizard, DO NOT Touch For 5 Minutes!
* After 5 Minutes, Reboot The Phone... ALMOST DONE!
14. Once you have finished installation, and your phone is working (all except WiFi), you will need to re-install SafeStrap from your SD card. This is a quirk of the stock MI1 bootloader, but can be worked around. Simply re-install SafeStrap when it disappears. Once you have SafeStrap Recovery installed again, reboot your phone into recovery directly from SafeStrap -- DO NOT USE THE PHONE REBOOT MENU TO REBOOT INTO RECOVERY.
15. You will repeat the process you used in originally flashing the ROM, but instead, this time you will flash the file jfltevzw-MI1-modules.zip that is on your external SD card.
16. When flashing is done, tap on the "Wipe Cache/Dalvik" button to clean up and make the kernel recognize the new modules when it loads.
17. Reboot your phone.
18. Once your phone comes up, you will now have WiFi. Enjoy!
Warning: I cannot be held responsible for anything you do to your phone. Anything you do to your phone is your responsibility. I am simply giving your the benefit of my experience in this guide, and I cannot help it if you don't follow it exactly.

That's curious -- mine would show the APN's with an activated SIM, but no signal whatsoever. This is what I had to do to use anything other than Verizon's CDMA here in the US. I was told that Verizon locks out the US GSM frequencies in their kernel so that you can use GSM outside of the country only.

I wonder if something changed in the later updates. As of MDK/ME7 it was working. I was able to get AT&T HSDPA after putting in the APN data. Voice worked without any of that.
As a part of their 700 Mhz spectrum agreement they had to be sim unlocked. My wife is using a VZW iPhone with an AT&T sim without problem. Did you see any sort of signal when you had the sim in (no data indicators, just signal bars)?
Anyone try stock MDK ROM and MJ7 Modem on ATT or Prepaid ATT with LTE active? Is this possible? In service mode I see both Band 17 and Band 20 as new selectables when updated to the MJ7 Modem
My 2 cents
unlocked out of the box
the sch-i545 is unlocked out of the box. no mod required. the only issue i have with AT&T is caller ID formatting has a + in front. Otherwise once with APN added, it works fine and able to get HSPA+

No -- no bars at all -- just an empty triangle. I would get the occasional flashing small triangle just above the signal indicator (searching for data, I believe), but the bars would never show. About half the time, I would get a red "NO" circle over the indicator, too.
As soon as I flashed Darth Stalker, though, it glommed onto signal & data lickety-split. I'm happy with it now -- in fact, I did a second one and sent it to my girlfriend in New York.

Before I left Verizon, while it was still on MI1, I flashed the MJ7 radios -- it virtually killed my transfer speeds. Went from almost 20 mbps to less than 10.
I've been through allot of this trial and error as I've always used GSM services in the past and before my S4 used a Verizon Note 2 with Straight Talk "AT&T". I got lucky and got an MDK and I've helped a friend with an ME7 on same service.. so I've worked with them both. What I found right away was that the Verizon CyanogenMod builds do not work properly with GSM phone service properly.. then I got a tip and made a custom VZW loki'd ATT recovery and started flashing the i337 CM ROMs and everything worked perfect from that point on.. I still have to do some work swapping files around when I want to run custom kernels.. not sure why most of the devs decide to pre-patch the kernel images instead of loki patching them during the recovery flash process as this would make a universal VZW/ATT kernel.. but it works non-the-less. As for the ME7 i545, the stock rom worked as long as you selected global mode but you'd still get the non-verizon sim error. Used SS with the GE 4.2.2 ROM and it works perfect with his GSM service.

The radio flashing happened while it was still a CDMA/ Verizon phone, before I flashed Darth Stalker. It really cut my LTE speed. Flashed the original MI1 radios, and I got the speed back.
Now, with Darth Stalker, I am on HSPAP:15 or HSPA:11 but the indicator says 4g -- I get comparable throughput as I did on Verizon.
Anyone getting LTE on ATT or prepaid ATT like goPhone, StraightTalk, AIO with the MJ7 radio?
Guys I actually have un-used AT&T go phone sim card I need it for someone to simply remove activation on iPhone. I put it in my S4 VZW and it showed AT&T as service provide so you don't need to mess with custom roms.

I have a CDMA SIM for 1x and EVDO here in India, we have been using GSM after the unlocking without any extra APN settings. Since the author has mentioned other networks, will this procedure help in using other CDMA SIMs in Verizon S4?

No, I think you misunderstood the nature of my original post. It was meant to illustrate how to get away from the high phone bills with Verizon here in the US -- since Verizon locks out all GSM US carriers in the RIL, you MUST replace the Verizon stock ROM in order to be able to use the Verizon phone on any US carrier which uses GSM technology.
You can still use foreign GSM carriers with the stock Verizon firmware, but there is no known method to "open up" the Verizon stock ROM for the use of the phone on US carriers on GSM -- many have tried, and everyone has failed. The only viable option is to completely replace the stock ROM and kernel -- which was the purpose of my "tutorial" here.
If you are in India, and you have a Verizon CDMA S4, you simply need to pop a SIM from a foreign GSM carrier into it in order to use GSM there -- you will NOT be able to use GSM here in the US, though, because of Verizon's lock-out logic contained in the RIL (Radio Interface Layer). I am not sure about the use of the Verizon US CDMA phone on foreign CDMA carriers, though.
Hello Everyone!
This OP is meant to be a reference for anyone who may attempt to "unlock" their Verizon S4 so that they can use another carrier's SIM in their Verizon S4 (SCH-I545)
A few weeks ago, I naively followed a guide to unlock my S4 so that it could be used with other carrier's SIM cards. Example Guide (There are many of these throughout the web): http://forum.xda-developers.com/showthread.php?t=2282683 - These guides are NOT meant to used on Verizon branded S4's.
For the record, I followed this guide in an attempt to change some of my network settings in order to get SMS working on a ROM, and did not realize the gravity of changing settings in the Service Mode Menu. To make a long story short, I changed the PERSO SHA256 status in the Service Mode menu (This menu is available on TW ROM's) and also attempted to restore the "Golden Backup" to the NV (Non-volatile memory - I believe). This inadvertently resulted in disabling calling and SMS on my phone. I later learned, and members like @k1mu have talked of this before:
Verizon S4's DO NOT NEED TO BE UNLOCKED
(and already have the PERSO SHA256 status set to "OFF" anyways.)
Our S4's are already capable of connecting to GSM, LTE, CDMA, and other some other network types for different carriers. If you decide to change your carrier to AT&T or Straight Talk, you can do so by changing out the SIM, changing your Network Mode, and setting up new APN's (all of which should be possible on a stock ROM). Although, I understand there are still certain limitations on our S4 with specific bands and network types that may not result in the most ideal performance on another carrier's network. There are also guides and threads throughout the forum that discuss different advanced settings and modifications to achieve certain capabilities on other carriers networks with our phones.
--------------------------------------------------------------------------------
The following information is in reference to MDK users. However, if you are on a different bootloader, Please read the end of this fix for a possible solution.
For those (MDK users) who have attempted to "unlock" their Verizon S4's and are having issues with SMS, Data, or Calling:
There is no way, that I determined, to reset the setting in the Service Mode menu to restore SMS and calling. I was able to change a lot of settings like network bands and data settings, but nothing to remedy SMS and calling. I even went to a Verizon retailer and got a new SIM card (which somehow restored SMS - depending on different Service Mode settings, ROM, and modem). I think Service Mode settings have an affect on both the phone's internal settings, as well as on the SIM card.
It took me many days, a lot of research, a lot of experimentation with Service Mode settings, and getting a new Verizon SIM to stumble on a solution to my issues. My solution arose form this post by @colton22 http://forum.xda-developers.com/showthread.php?t=2650296.
This is how I solved the issues:
- ODIN back to the stock MDK ROM (excellent guide here: http://forum.xda-developers.com/showthread.php?t=2301259 )
- Factory Reset the device via the settings menu Settings > Accounts > Back Up and Reset > Factory Data Reset > Reset Device.
- And Victory! Just follow the above guide to also re-root the device and re-install your custom recovery
Click to expand...
Click to collapse
I know it may seem obvious to ODIN back to stock, but that is not what fixed the issue. I tried that multiple times, tried many different modems, and tried many different network settings. However, the key to this is the Factory Reset via the touchwiz menu. I wiped my phone dozens of times, but it required the stock Verizon ROM factory reset option in order to regain full functionality.
This leads me to a possible fix for non-MDK users:
- It may be possible to restore full functionality by just doing a Factory Reset (via the settings menu) in any TW ROM
- I am unfamiliar with Safe Strap and how the whole system works, so it would be interesting to see if someone not on MDK could remedy this issue if it arose.

Glad my post helped. Reading that old thread again gave me goosebumps As I thought I really messed up my phone. I, as well as many others, appreciate people like you who take the time to make sure no one is left behind. Thank you!
My S4 received the crack of doom so I am now typing this off my Edge!
Thanks again!

If you are asking about how to recover your phone's SMS and calling capabilities because you tried to unlock your phone via the service menu, then here is my advice:
I have not had anyone test this method that did not have MDK yet. However, I imagine flashing one of Surge's Odin Tar's for your specific bootloader version would be your best option. For NC5, I would recommend using the VRUFNC5 Full-Wipe zip found on this thread: http://forum.xda-developers.com/showthread.php?t=2735172
You can try wiping you phone with the above zip via Odin, then going into the settings menu and doing a Factory reset (as mentioned in the OP).
Let me know if you get any positive results!
However...
If you are trying to gain access to the service menu, you will need to find a guide somewhere else. Verizon S4's do not require a SIM unlock, and therefore I do not recommend you trying to do so.
FYI, I have used this phone for quite some time in Indonesia, maybe almost a year, and I don't get any problem using different carrier. No need to unlocked it anyway, just put my GSM SIM Card (Telkomsel) from the first time I bought it and then it works very well. The only thing that might need to be done is adding a new access point, which is only "internet" for both username and password, if you flash a new ROM.
Here's my situation I inherited a Padfone X from my brother (unfortunately he passed away last month) and he had it setup I think as a padfone S running Android 5.0 using build LRX21M.WW_padfone-12.2.2.27-20150721 on TMobile. I need to convert it back to stock rom or an AT&T compatible revision. A detailed process would help. 'Ive tried installing other ROMS but the phone wont take them off the SD Card and Ive tried doing an ADB sideload of a stock rom I found but it gives me a bad header message. can anyone help or will I have to send this phone to ASUS to be restored?

Im on at&t with this ww rom having no issues. Pretty odd why you want to go back to this crappy firmware at&t and asus gave us.
The only way to get it restored is from a back up. However this will not restore band 17 unless he has an efs backup hiding somewhere.
Best way to go is to downgrade the ww version to 4.4 using a downgrade version provided by asus.
Its best that you flash that under twrp. Once there locate a back up of a padfone x firmware and then just restore it from there. But wipe everything before flashing the back up.
Thats what I think would be best for this. I havent done it because I love ww firmware on a pfx, it made my phone more functional and alot more faster.
can you help me get it to show 4g lte properly or run it? I just updated to the latest and still have the issue. I think my brother modified the modem software so I need to regret not back to the original. He didn't leave s backup anywhere.
Hello,
I have a SM-G965U1 I bought it new and unlocked and I had it on Boost Mobile (sprint) for a year and switched to Mint Mobile (T-Mobile). I keep getting prompts for updating PRL and Profile after an OTA a few days back I looked up the firmware and such and noticed my firmware and radio is for Sprint version side. Is there a way to wipe the radio information or update it so it starts getting the T-Mobile OTA's? I understand CDMA requires PRL and Profile data and GSM does not but these pop ups are crazy.
Thank you!

You might need to flash a universal firmware to avoid future issues
Thanks I did but this phone outright at best buy unlocked and had it on boost mobile but thanks I see that it had installed the boost software. Is there a way to switch without wiping my phone and I am not sure what i should install i know how to use oden and such tho.

So the way I did it was I used Frija the firmware downloader tool and got the tmobile firmware make sure that its greater than your current firmware. Then if you chose one of the CSC options I forget which one, it won't wipe your stuff. There's home and something else, I don't remember which one doesn't wipe but a google will probably help you out. I had Sprint and bought out my phone and then flashed the TMO firmware and now have a TMO sim in my phone. Also if you hate phone carriers and the software they use, I was running the SM-G965U1 firmware but I wanted the visual voicemail and stuff so I just flashed that.
Yea ok... this phone isnt rooted or anything I just might look into it but I was looking around but I'll take your advice and look for csc in that search aslo.

Yes you can switch the firmware on the sm-t867v from Verizon to TMobile or Sprint. It keeps the bootloader locked down so root is still impossible but since you are not looking to root it just switching the firmware version should work just fine. I personally have metro pcs and their $15 unlimited tablet data plan on mine and I switched my firmware to TMobile so I could pick up the LTE bands it would not connect to with the Verizon firmware. All you need to do is download the modified Odin 3.14 and the firmware of the carrier you wish to switch to. It HAS to have the same base model. For example I went from the SM-T867V firmware and flashed the SM-T867U firmware to the device. So your firmware choice absolutely MUST have the SM-T867 in the beginning of it. Any other firmware will most likely brick your device if Odin even allows it to flash. The thing that makes the difference between Verizon and TMobile is the user userdata file. You must flash it with the rest of the firmware files, So BL, AP, CP, CSC, and Userdata. Don't worry, the stock firmware will come with the userdata file. Also its best that you don't flash the CSC-Home file but flash the regular CSC file as the home one will not delete your data and its probably best to do a full wipe when switching firmwares, so make sure you back up anything you don't wish to lose. When the flashing is finished it will boot and instead of the white screen with big red circle for Verizon you will get a pink TMobile screen and it will be model SM-T867U now. All OTA updates will still work without problem and you will get a functional dial pad which works for all the secret menus and all that fun stuff. BTW, I take absolutely no responsibility if for some reason it messes up or bricks your tab s6 lte. Goodluck and enjoy your non Verizon tablet.

I'm glad it worked for you without any major issues. This was the first thread I've given any real instruction on. Hope your tab continues to work perfectly. I broke the screen on mine so the only thing it's really used for is an android PC. Thank God for the Tab S6`s ability to output video so easily and the Samsung DEX software.
