SimLock Solution For All 4.3 users

Hello to you all
I would like to show all of you 4.3 users the solution "elvisypi" gave me in my private mail and finally i succeed to unlock my device.
So all of us know that sprint or google changed the way HtcOMADM works and we can't use the original system for unlocking our device.
So here is the solution that "elvisypi" gave me :
1. Download the "Stock with goodies 4.3 ROM". Don't flash it wet. (link : http://www.mediafire.com/?9y21d2wlszh6d6c )
2, With an archive viewer like winzip open the ROM.zip and go to /system/app
3. replace 2 apps which I have attached: HtcOMADM_SettingsPlugin_SPCS.apk and HtcOMADM_SPCS.apk. Just drag and drop and replace.
4. Finally flash the ROM.
5. Install the HTCOneSIMUnlockHelper and follow the onscreen instructions.
This system works 100% and this way you can be on 4.3 rom and still have an unlock GSM sprint device.
again , many thanks to "elvisypi" for his great support

sim unlock
Hope it does
downloading....

Would this work with other ROMs like insercoin?

You must use a stock rom for this to work

Hey, are you using this with Tmobile or another service?

I'm not using t-mobile , I'm not from the US but it should work with any GSM sim after the unlock is done

I've followed your directions, using the ROM you provided (only difference being flashing the root-fix) and I get vDM errors every time I boot and the app says it's unlocked but my Tmobile SIM gets no signal. Is there any other way i can check if my phone's unlocked?

Yes I have, it says preparing SIM card but I never get any bars. I read in another thread that I need to be on an older radio in order for Tmobile to work. And for that I'll need s-off which I can't. Sigh.

Flash the release radio and let us know, I'm interested in using an At&t card for when I need a good data connection.

It didnt work for me?
I did exactly what you said an When the phone starts up it says unfortunately ui has stop working an it keeps popping up an i cant do anything with my phone

Thank you for this already pressed the Thank you button also
i was getting annoyed that i couldnt find the files before i found this thread

HTC ONE
I did everthing s-off....flashed to the old radio baseband....tried everything still havent got any signal....who know what a problem?
The only thing is that I've flashed my sprint htc one to the Straight talk. Could it cause a problem?

I am also trying to unlock for T-Mobile. Running into the same issues as others. I was reading a thread where someone was apparently using it on T-Mobile, and PMed them on how exactly they did it but never got a response.
Would love to hear if anyone has it working on T-Mobile

This works. :victory:
Only need to extract, modify and zip again.
Flash with TWRP.
And everything is working normally, no need to reinstall or root, or whatever.
The only problem is that every time I turn on the phone, I get the error message VDM, but it disappears instantly, without stopping or forcing any application.
I live outside the U.S., and continues to operate all perfect with SIMUnlockerHelper. :fingers-crossed:
My device: Sprint Htc one = Unlockboot, TWRP, SIMUnlocker Helper, Root, and the rom on the top of the post. (benny's 4.3 LOL)

it actually works, but if you're using a sense rom I think you only need to download the apps in the op and replacing in system/app
I did this with insertcoin 6.0-4, the unlock helper app didn't recognize the rom, but with the terminal emulator method it worked just fine, tried with a sim and all fine ... then put again the original apks and you don't have to deal with any error popups

Interesting. I was under the impression that our version of this device did not support domestic (only international) GSM bands, hardware wise.
Is this version of sim unlocking different than what you would get if you asked Sprint? (they do allow you to unlock it if you meet certain criteria, like good account standing)

it supports the bands, but all the radios except the original one block domestic gsm carriers. if you still unlock and use that radio, it'll work.

Not working
I tried everything mentioned above, ( Unlock bootloader, S-OFF, Root) also changed the 2 apps in the system for the 4.3 ROM Stock rooted deodexed and then used the SIM unlock helper.
Then Got the same result : No GSM signal, and the SPRINT logo still on the top when I make a call, the same answer comes: " Error number 16 script 3."
I'm using Straight Talk Sim by ATT.

[Q] Atrix HD: T-Mobile SIM Not Allowed On Network [SOLVED]

I'm pulling my hair out trying to get my Atrix HD to recognize a new T-Mobile SIM card. Here's where I've been and where I'm at now:
- Purchased AT&T Atrix HD MB886 on ebay preloaded with fresh install of CyanogenMod 10.2 Nightly build from 9/28/13
- Inserted new T-Mobile SIM card, not prompted for unlock code... Hmmm
- Attempted to register on T-Mobile network, received error message "Your SIM card doesn't allow a connection to this network"
- Attempted again with second new SIM card, same result (both SIMs work in another phone)
- Upgraded to new CyanogenMod M1 build from 11/2, same result
- Performed TWRP/CWM-based recovery>wipe data/factory reset..., same result, though now it shows on the lock screen "SIM/RUIM IS PERSO LOCKED" (may have been there before, but I don't remember seeing it)
I doubt if the phone is carrier unlocked, so I expected the prompt for an unlock code. In researching I found several people for whom the factory reset worked (even prescribed by Motorola support) to solve this when a new network SIM was used, but sadly not for me. What should I try next? Thanks.

Go back to stock with RSDlite Ok
I imagine you are bootloader unlocked and rooted.
Once on stock insert the new sim card and unlock it inserting the code into the prompt.
Once unlocked the rest is history. Just root the phone again as is very probable that you will loose root.
Then flash the ROM you want and happy testing....

seems good to me too...Search RSDlite as he said...get stock flashed up..and see if it asks for a code or not!!

Thanks. I was afraid I would need to go back to stock. Not that big a deal at this early point with the phone. I'm flashing the image now. It's been going for over an hour. How long should this process take?

An hour seems far too long. It's been a while since I flashed a stock rom but I don't recall it taking more than 10 minutes,

That's what I thought. So I powered off the phone, RSDlite said it failed. Now the phone boots directly to fastboot.on a short press of the power button, with the reason stated as "failed flash". It had hung.on 18/23 flash system "system.img. I'm re-flashing now, but after 60 minutes it's still hanging up at the same place.
I'm following the posted RSD Lite guide from last April very carefully. However it does mention that you can not downgrade from JB to ICS, I'm not doing that, but I am going from 4.2.2 (Cyanogen 10.2) to the 4.1.1 JB stock. Hope that's not a problem. I'll try again at work today with a fresh copy of everything and differnt PC. Thanks for the help.

Make sure you reboot to a new fastboot mode with no errors

All Is Well!
The re-flashing on a different PC worked quickly and correctly. :good: I'm back to stock JB, and was correctly prompted to unlock the phone when I inserted the T-Mobile SIM. It also kept the bootloader unlocked (as the Motorola Warning informed me). Now on to the mods. Thanks to you all for the assistance and advice. You're great!

Good to know help came along and glad to see you back at testing. Lol

Once the bootloader has been unlocked, it cannot be relocked. After you enter the network unlock code, it's permanently unlocked. Sounds to me like the phone is now fully and permanently carrier and bootloader unlocked.

I'm back in business now. AT&T sent me the unlock code in just 12 hours (had my fingers crossed), I unlocked, and T-Mobile was setup automatically. Re-rooted, Reflashed ClockworkMod Recovery, then Cyanogenmod 10.2 M1. It hung in a boot-loop the first time, so I erased all caches and did a data wipe/factory reset, and the second CM flash worked fine. Learned a lot in this whole episode. Thanks.

happy ATRIX !!

Gsm unlock emergency calls only!

My bootloader is unlocked with H-Boot 1.56, I'm S-off, rooted and TWRP recovery. I'm on the 6th rom I've flashed (Tried CM 11 Nightly, CM 10 Snapshot, Stock Deodexed rooted 4.1.2 and 4.4.2, MIUI, Viper Rom) and I've been working on this device for about 48 hours non-stop. I am NEED of assistance if ANYONE can offer it.
Does this sim unlock also work for phones that are currently registered on Sprints network? Like the account is still active? I've got a Sprint HTC one I've performed the Sim Unlock attempting to use my T-Mobile sim, but it says "Emergency Calls Only," and "Searching for network/No Service" I've got a red X where the signal bars are. Of course No text, no voice and no data. I've gone into the *#*#4636#*#* service menu and changed the settings to WCDMA, but NO dice. Yes, I went to mobile settings, searched for service and nothing appears, just a blank screen! The phone does recognize my Sim card and even shows my cell number and IMEI, UICC as well. I've even attempted to change RUIM settings in DFSCDMA Tool but that does very little. I have changed the radio around about 5 different times, currently using 3.04.651.2 with NO fix. I have searched high and low on these forums and haven't found anyone that can help me.

Try the third method, it should work. By the way if you want to bypass hands free activation, rename HTCSetupWizard.apk to HTCSetupWizard.bak

Only do this if you're unable to get past the setup wizard.
1. Boot into twrp
2. Wipe dalvik cache
3. Mount system
4. Go to the file manager in advanced
5. Go to system/app
6. The file should be there, rename it.
7. After that unmount system, wipe dalvik again and reboot, and you should be good.

After SIM Unlocked, the phone recognize the SIM, but o Signal

Hi everybody
Actually I am not fresh or new to this kind of unlocking, i made many successful processes, but now i am facing a very strange situation, i had an HTC One for sprint updated to the latest sense 6 , i performed all the unlocking steps successfully, and i get it unlocked.
the problem starts when i inserted the local SIM card, it recognize it and ask me for the network setting, and when i am trying to do the last step (changing the network to GSM) it refuse !! and keep put the network to Automatic mode and tell me no network available!!
i tried almost everything, downgrade to previous Viber ROM ( sense 5.5) S-off , update firmware, etc.. with no hope
maybe i pressed something is the API menu by mistake which caused me all this problem,
any thoughts or ideas will be highly appreciated

today I made the same thing with m8 , same situation, any help pls

Honestly.. I'm thinking it has to do with the firmware. Try method #3 here. If that still doesn't work, try it again for good measure.

I had same issue. My phone is s-off. The way it works for me was going back to 4.3 and i did the method with sim unlock helper. After that i restored my 4.4.2 sense 6 stock rom and unlock works but no mms o data (data 3g and H symbols shows!) I went back to 4.3 and used google to search how to fix gsm connection. You will find a tutorial from here. (Xda) I used cdma tool. Btw...you need to find your MSL code ....that tutorial show you how to do it. Good luck!
To going back to 4.3 i just flashed a 4.3 rom from reckvery. Look in development threads.

[GUIDE] [fixed] SIM UNLOCK after lollipop

this thread is just for lollipop 5.x m7wls (sprint) based on sense roms
no need to S-OFF
if you are on kitkat or less here or here if you are on the stock ODEX rom
1 - you need just to unlock bootloader from htcdev.com
2 - TWRP or any other here is the TWRP for m7wls(sprint)
3 - flash SuperSU
4 - its time to flash HtcOMADM_SPCS
5 - install sim unlock helper.apk
6 - Insert your SIM card, you may see this massage No Network Found
Code:
Select "YES" to switch to global mode
Select "NO" to stay in the current mode
but do not worry since your phone dose not say invalid sim card . so now go to setting , mobile data . and chose GSM/UMTS only. tell now you wont see any signal , just scroll down to Available GSM netowrks ,then Search networks you will see a list of networks and only one that is available, chose it .
now if you want to stop the annoying vDM crash massage flash the stock-HtcOMADM_SPCS .
Its better to relock your bootloader and flash the RUU rom so every thing works well and you wont see the No Network massage again .
That's it ^_*

it really works but, it didn´t solve my problem i guess my problem is not sim unlock i can not have signal for gsm it stuck in CDMA but in *#*#4636#*#* it shows up like radio turned off i want to turning on but i can not,:crying:
anyway thanks:good::good:

I've tried your guide and elvisypi's guide, but neither work. I'm using a rooted M7, lollipop, stock ROM.
When using the SIM Unlock Helper app, I get "OS Check Fail! You aren't running HTC Sense!", but if I hit the back button I end up at a screen that states "Device verified, root available, sense rom (yes)". Hitting Start does open up the menu, but never before a vDM client crash. After hitting Sim Unlock and it hanging for a few seconds, the log is empty after hitting back to return to the unlock helper. The screen says "Log empty, did you run the program first?"
It seems to me that "vDM" is what is supposed to be doing the work, and it's crashing so it can't...

when OS Check Fail! appears to you press Display SIM Unlock Log then go back and press start and scroll down to sim lock
if that menu did not appear to you try flashing this instead

Not unlocking
Hi I am have bootloader unlocked, intalled TWRP, and rooted. Tried with Stock Sprint Lollipop ROM and menu would not pop up. Flashed to Viperone 8.0 and I am able to bring up the menu. Once Sim Lock unhighlights I hit the back button and get the SIM unlocked successful message. The reboot in that screen does not work for me so have to hold power button down and reboot. I have changed settings to GSM and WCMDA preferred. Next pop in an ATT SIM and a Cricket but still get invalid SIM. Any ideas? Also, I am S-On as I have been unable to off with HBoot 1.61

Hi, I bought a Sprint HTC One M7 (running 5.0.2) from someone figuring that I'd be able to unlock for use on Verizon (because every phone can be unlocked...... right? ). I first unlocked the bootloader with HTCDev, ok good. Then I ordered a SIM unlock code off the interwebs thinking that I could just go get a Verizon SIM from them and then enter the code when prompted. Took the phone to Verizon and they couldn't help, said that IMEI was not valid and they couldn't give me a new SIM because the current phone I have (Incredible 2) isn't eligible for a SIM only upgrade, then they said I should just purchase an upgrade with the EDGE plan (yeah right). I then used the SIM card of a friend who has an M7 on Verizon hoping that I'd be prompted for the SIM unlock code then, but I only got "invalid SIM......"
So, I stumbled upon this thread and followed the procedure to flash TWRP, then SuperSU, confirmed that I'm rooted, and then flashed HtcOMADM_SPCS_2.zip, and ran SIM unlock helper. I got the same error as the other guy "OS Check Fail" and vDM client crashed, but then I press back and go through the SIM lock part and reboot. So now I can put my friend's Verizon SIM in and I get no SIM error, but I am still not prompted to input the unlock code for my IMEI. Any Ideas, or is it not even possible to use a Sprint M7 on Verizon?
EDIT: I am now S-off with sunshine (hboot 1.61)
EDIT 2: Ok, now I'm getting to a point where I put my friend's SIM in and it prompts "preparing SIM", "SIM card inserted, tap to complete setup". Once I tap the notification, I get taken to a screen that says select your carrier. It takes a little while to load the carriers but Verizon appears, but after I select verizon, the page disappears and nothing further happens. It then repeats the loop from "preparing SIM".
EDIT 3: From TWRP I wiped all data including the OS. Then I got stuck at the splash screen, reflashed [STOCK ROM] [5.0.2] [SENSE 6] Sprint 6.16.651.2 rooted from phonegeekjr (PhoeniROM ?)

I think You need to change the CDMA via DFS so it can be recognized by SIM card
Why
Sprint always use the CDMA as PRL that you can write it via DFS while Verizon use this type of network as a SIM card so that after using sim unlock helper your phone dose not say "invalid SIM" but it didnt show the network signal

As far as I know, the Sprint and Verizon M7s have custom radios operating at their carrier frequencies. Sprint's frequency band is not the same as Verizon's, and even after unlocking, the radio can only scan within its band. Your radio simply can't see Verizon's tower. It seems like your process completely worked, though.
I haven't gotten the chance to try again, but I am planning to eventually.
Also, it is possible to S-OFF through any other method than Sunshine? It'd be nice not to have to pay for that... Is S-OFF absolutely required to SIM unlock/ flash custom roms/ change files at the root level?

This does NOT work...
I think it is pretty obvious that THIS METHOD DOES NOT WORK...
I basically ran the latest RUU - Sprint Stock ROM which put my phone to Lollipop 5.0.2 - Sense 6.0, HBOOT 1.61, S-ON
I unlocked bootloader with HTC DEV, installed the latest TWRP, and rooted the phone, so it is all LATEST and GREATEST as of this post date...
I ran BOTH of the HtcOMADM_SPCS_2 files - both OLD and NEW - and neither one works. NEW is actually worse because the vDM client crashes each time you even try to launch the SIM UNLOCK HELPER app.
With the OLD file you can get to the menu and you can click on SIM LOCK, but nothing gets written to the log before or after reboot, plus when you go to *#*#4636#*#* you can select the connection type, since it is set to CDMA but every time I change it to - GSM only - it will reset to CDMA only when I go back in. So the change refuses to save and I keep getting that prompt saying:
No Network Found
Select "YES" to switch to global mode
Select "NO" to stay in the current mode
So it seems to want to force you back to CDMA mode.
If we are supposed to be running a CUSTOM ROM then please say so, but I am testing with the STOCK ROM and it seems others are NOT having any luck.
So if someone has it working then just let us know WHICH ROM you are using and which files you are using, because it sounds like we are being asked to QA the hack...
Moving on to another solution now...
:crying:
P.S.
Why is someone posting about a VERIZON phone in the Sprint section, kick them out because they add to the confusion...

Wow! OP was edited with a fix 4 hours after I'd figured it out myself. Just made an account to clarify that you need to downgrade the radio if it's too new. I had a lot of trouble trying to unlock it before figuring that out (and I went through an entire series of downgrading and flashing multiple ROMs until I found it out). Here's a guide I made that worked for me.
Have an unlocked bootloader first with HTCDev like said in OP. There's no need to have S-OFF or downgrade anything except radio.
1. Install TWRP.
2. Flash a lollipop ROM (I used Viper 8.0.0) using TWRP. (You can probably skip steps 2 and 3 if you're already on lollipop.)
3. Once booted, go through first time set up.
4. Restart into TWRP and install SuperSU.
5. Reboot and flash the radio (1.00.20.0315_1.29.651.7.zip from elvisypi's thread) and then flash HtcOMADM_SPCS.zip (I used the 4.3 version from chas123) using TWRP.
7. Reboot into System and install the com.viper.simunlockhelperfree.apk (Below; couldn't find where I got it from) then go to display log, press back, press start, then scroll down and press simlock. You could probably also do this using the Terminal method.
8. Wait a few seconds until it unfreezes and reboot.
9. Once rebooted, plug in your sim and go to the phone dial and put in *#*#4636#*#*. Go to Phone Information and set the network to WDCMA preferred. (It might spam you with "No Network Found," so just check do not show again and press No to switching to global mode.)
10. Exit out and open Settings then go to Mobile data and make sure the Network mode is set to GSM/UMTS Only. Scroll down and go to Access point names. (Found steps 10-13 from savage25rcracer while searching through the forums.)
11. In the APNs, choose your carrier and press back.
12. Go to Available GSM networks and press Search Networks.
13. Wait until it finishes and select your carrier.
14. Now you should have service and you are now unlocked on lollipop.
One problem I have is that when data is turned off, it never connects back to data when turned back on and I have to repeat steps 9-13. Any help with that would be appreciated. I did this method with HBoot 1.61 and S-ON and I am using a T-Mobile Sim. Hopefully this works for you guys!
EDIT:
Turns out that switching it to GSM Auto (PRL) made it automatically reconnect for turning data on and off, but data doesn't work after reboot until I repeat step 12.

Check my older post I have a fix for the in an out signal and it reconnects automatically... Thank me later. Spread the word... It's well worth it. I use it.
Sent from my HTC One using XDA Free mobile app

i tried with STOCK & Viper ... not working
with Stock SIMunlockhelper didnt give me MENU after i hit START
with viper it takes about 2 mins freezing when i hit SIMLOCK... then still nohting after reboot Network operator DIMED & alot of times it give me ERROR (vDM Client isn't responding)
NOTE : on lock screen it says (Invalid Card)

It doesn't say invalid sim,i selected ATT from the list of the carriers,i selected GSM/UMTS under mobile settings but my Network Operators Menu is grey and i can't select ATT there.Any ideas.

REVISTED - Did this work?!

Wow! OP was edited with a fix 4 hours after I'd figured it out myself. Just made an account to clarify that you need to downgrade the radio if it's too new. I had a lot of trouble trying to unlock it before figuring that out (and I went through an entire series of downgrading and flashing multiple ROMs until I found it out). Here's a guide I made that worked for me.
Have an unlocked bootloader first with HTCDev like said in OP. There's no need to have S-OFF or downgrade anything except radio.
1. Install TWRP.
2. Flash a lollipop ROM (I used Viper 8.0.0) using TWRP. (You can probably skip steps 2 and 3 if you're already on lollipop.)
3. Once booted, go through first time set up.
4. Restart into TWRP and install SuperSU.
5. Reboot and flash the radio (1.00.20.0315_1.29.651.7.zip from elvisypi's thread) and then flash HtcOMADM_SPCS.zip (I used the 4.3 version from chas123) using TWRP.
7. Reboot into System and install the com.viper.simunlockhelperfree.apk (Below; couldn't find where I got it from) then go to display log, press back, press start, then scroll down and press simlock. You could probably also do this using the Terminal method.
8. Wait a few seconds until it unfreezes and reboot.
9. Once rebooted, plug in your sim and go to the phone dial and put in *#*#4636#*#*. Go to Phone Information and set the network to WDCMA preferred. (It might spam you with "No Network Found," so just check do not show again and press No to switching to global mode.)
10. Exit out and open Settings then go to Mobile data and make sure the Network mode is set to GSM/UMTS Only. Scroll down and go to Access point names. (Found steps 10-13 from savage25rcracer while searching through the forums.)
11. In the APNs, choose your carrier and press back.
12. Go to Available GSM networks and press Search Networks.
13. Wait until it finishes and select your carrier.
14. Now you should have service and you are now unlocked on lollipop.

Well, it seems this is the ONLY SOLUTION that worked for me, because I tried the Bad Boyz custom ROM that some others have suggested but it does NOT seem to work and there are "bugs" like the status\notification bar disappearing when you start to mess with the ROM. I flashed the Viper 8.0.0 ROM with TWRP and everything loaded properly except for one little "bug", which is this constant non-stop blinking NFC icon in the status bar so I might have to find another ROM. I wish I did not upgrade, so if you have ANY HBOOT under 1.61 - DO NOT UPGRADE WITH OFFICIAL ROM - because once you have 1.61 then you cannot S-OFF although you can downgrade the radio with S-ON and it is just a matter of unlocking the bootloader.
2 Notes:
1. Make sure you install SuperSU and do not rely on the Viper version, so let it uninstall any other SuperSU after installing from the Play Store. I believe the SuperSU installation will fail for you if you install through TWRP, but ViperROM should be rooted and instead install SuperSU from the Play Store if TWRP installation fails.
2. When you run "SIM UNLOCK helper" it WILL FAIL the first time, because you need to have SuperSU give it permission so make sure you go to the LOG in the options. Afterwards, make sure you close everything and remove from latest apps list. Then run again, when it fails then open LOG then hit BACK and now it will show you that you PASSED THE TEST. Then START then scroll down to SIM LOCK and wait like a minute or more because it took a LONG TIME for mine to un-freeze but then I hit REBOOT once it came back which is right there in the same list. If you doubt it, then reboot and do again but I was able to get it to work and then when I changed options in 4636 it would look for my SIM and did not give me any errors.
Anyway, I was able to follow all the steps here and the key seems to be downgrading the radio, because nothing seemed to work until I downgraded the radio version and then I tested it with both an AT&T and T-Mobile chip that I have lying around. The T-Mobile chips seem to work with no problems as others have noted, so you are able to make changes, register on the network, and set it up but I had problems with AT&T although I got farther than with any other modification. The AT&T chip will let you select the AT&T network, but you will not be able to scan for networks and you get NO BARS although it seems to be connecting or doing something although I suspect AT&T or something in the software is blocking you from connecting 100%.
So I cannot say 100% this SIM UNLOCK worked, but at least I was able to get to options that I could not get to before and I tried BOTH chips and only the T-Mobile chip seemed to work without any problems, so I suspect what others have reported is true and the Sprint HTC ONE M7 seems to be giving you problems with DOMESTIC US Carriers. I will be able to make a DEFINITIVE test in 2 months, because I am going to Peru and I might as well take this phone with me so I will test the Sprint HTC One M7 with both Claro and Telefonica SIMs down there. I will even try to update to the LATEST Sprint Official ROM to see if the unlock stays and if I am able to get GSM to work with overseas SIMs then the SIM UNLOCK worked, but you might as well not bother using it in the United States, so hopefully this will help others once I post an update after July and this will end up my "overseas" battle phone unless I pawn it off over there.
See you then...
:good:

Not to derail the thread, but I think there is a fix in HUB - Addons.
