SIMLOCK after 10 minutes - Sprint HTC 10 Questions & Answers

I tried to mod my Sprint HTC 10 to Verizon by flashing a VZW image. The firmware flash went fine but I couldn't get a signal. Then I found out from jcase that loading VZW firmware on the phone would not work as the hardware is different!
So I signed up for Sprint and reflashed Sprint stock firmware on the device. After 10 minutes of usage with the Sprint SIM card, I get a message that says, "SIMLock Enabled - Voice and Data service will not work as SIMLock is enabled. Please contact customer service to unlock."
Once I reboot the phone, everything works again for 10 minutes until this message appears again and shuts off voice and data. Any ideas on how I can fix this?
I have S_OFF and the phone is unlocked.

[Q] Phone crashes - not network detected

Dear Colleagues,
First of all, my apologies if this issue was included in some other post, but I was not able to find it.
I have used the following tip to root my Atrix:
http://forum.xda-developers.com/showthread.php?t=1255548
Everything went ok until yesterday. I left my phone charging during the night and when I woke up, the phone displayed a message saying that "SIM Card is invalid". I've rebooted the phone and everything went back to normal. 20 mins later, the same error showed up. Rebooted again, and it worked again. A few minutes later, I've tried doing some calls and the dialer looked like calling but it was not able to connect. I have restarted again, and the same happened, only that this time no data was being transferred. I checked the APN and there was none. So it seems that it was deleted by the phone. I re-entered the APN info, everything worked again, but this morning the same happened after charging. Now my phone displays randomly the following error message: "The process com.android.phone has stopped unexpectedly. Please try again.", the APN is gone and it restarts randomly. Any clue?
Should I do a factory reset?
System Info:
Android: 2.3.4
Build Number: 4.5.91
Carrier: Movistar Argentina
Any help is greatly appreciated.
Thank you in advance.
Regards,
Fernando
Hey
Some questions:
1) Does your phone if from your carrier or did you sim unlocked it using an unlock code?
2) Did you unlocked your BL?
3) Do you run any rom or mod on your phone?

similiar issue here:
yes i have performed 1 and 2.... sim unlocked and bootloader unlocked
please help
thanks
edit:
i bought the phone "new" from ebay. everything seemed and appeared new and clean on phone so i am inclined to believe that it is in fact new. i have unlocked the bootloader, rooted the phone, and entered a code to carrier unlock it. the code appears to work as i have recieved the "phone is now carrier unlocked" message. however, where my bars should be i have an X. then, when i search for a network i recieve 3 networks: 2 att's and one tmobile. I am using a Claro (dominican republic) sim card. i try all three of the searched netowrks and recieve the same error for all of them: "network with limited service found." now i have an exclamation mark in my notification area which reads: selected network (att) is unavailable.
please help!!! i leave for the DR on sunday and need this phone to work!! thanks for your help in advance!

Tried unlocking for us gsm sim, think I've ruined it help appreciated

Got an LG G2 Lollipop from a friend, originally on Sprint but I can't switch to sprint, so followed procedures to unlock sim for use on tmobile (root on lollipop, international sim unlock) those went ok.
Everything I found went like this:
Edit:
ro.carrier=spr(or TMO, or SPR in caps, sources varied so i tried all suggestions)
ro.build.target_operator=spr (or TMO...etc)
persist.service.crash.enable=1
Once i did this I(I think the problem started on the target operator edit) I got so many alerts "Unfortunately, the process com.android.phone has stopped" I couldn't access settings, couldn't get back into the rom toolbox editor, couldn't press barely any buttons besides restart. Went into recovery mode, cleared the cache, no luck. Went back in to do factory reset as last resort...still no luck. Is there any way I can fix this? If this can't be solved via forum, anyone who is savvy switching from sprint to tmobile I will pay to have it mailed and fixed because I've researched this all week and still am not having any luck.
Much thanks

Flashed Verizon RUU, cellular radios, GPS, and camera now broken

Hey all,
So, a little backstory: I got this HTC 10 from Sprint not too long ago, and little did I know that I would be stuck with Sprint unless I reflash the phone firmware. (after research, asking HTC and Sprint, I received misinformation from reps stating that the phone would work on Verizon with just a carrier unlock issued over the air). Moral of the story: don't rely on customer service :silly:.
Fast forward to now, and I have rooted (temporarily to run Sunshine), S-OFF'd (using Sunshine), changed the CID (for Verizon), and flashed the newest Verizon RUU that developer Dottat kindly posted here.
That worked, full LTE, but then whenever the camera or GPS were accessed by any application, the phone would freeze with a black screen (though it seemed something was still running in the background, as notification sounds would still play, and I could exit by pressing the home button and waiting about a minute). After this, I tried flashing the Viper ROM just for kicks, but then the cellular radios only functioned with 3G coverage (no LTE in a coverage area), and GPS was still broken (the camera issue was fixed with this flash for some reason).
Unfortunately (or maybe not), I am pretty sure /system has been wiped multiple times. I also ran
Code:
htc_fastboot erase modemst1
htc_fastboot erase modemst2
after each install of a new ROM, then performed a factory reset from recovery (just a factory reset, nothing more).
Now I went ahead and used an official ROM from HTC's website in an attempt just to get full functionality working on any carrier. I flashed the USA unlocked variant (and changed the CID to BS_US001. MID is still 2PS650000), but now I am experiencing more missing functionality. The camera and GPS are still missing, and now the SIM card is not detected (when entering the access point names dialog, a message pops up stating that there is no SIM, or SIM error when I am using an activated AT&T SIM). When I enter the test menu (*#*#4636#*#*) and select any option for network mode other than what is default (LTE/CDMA), the new option won't 'stick' (it returns to default after a few seconds).
This sounds to me like there is stale firmware on the device from a previous flash, or that the firmware for these core peripherals is corrupt. Is there a way I can get these devices working again? Or am I now stuck with a bricked device ? I do still have a backup I took of what was installed stock by Sprint (all except for /data...but I don't need that partition, right?)
EDIT: Mods, I am terribly sorry! I meant to post this in HTC 10 Q&A. I don't see a way to delete a thread, so hopefully we can move it.

A MOD should move it soon.
I am not the best here, but hopefully can be of some help.
I would just superCID, save a step for flashing RUU's.
So, when you flash the Verizon RUU, does camera work?
(if you RUU and only have 3g, wipe the modems to get 4g back)
If your trying to use the phone on Verizon I would do the following:
1) Change your CID to Super, 11111111
2) Flash the US Unlocked RUU, http://www.htc.com/us/support/rom-downloads.html#unlocked
3) After it fully boots, reboot into the bootloader & flash the Verizon radio, http://forum.xda-developers.com/verizon-htc-10/how-to/vzw-how-to-unlocked-model-vzw-t3376743
4) Make sure the Preferred Network is set to Global, Settings>Mobile data>Preferred Network
5) Get to the secret menu *#*#4636#*#*, and set the preferred network type to "CDMA/EvDO/GSM/WCDMA/LTE Auto"
I use a Verizon model with the US Unlocked firmware. As far as custom ROMs, some work with Verizon's network and some don't. I'm sure theres a workaround but I've stuck with the US Unlocked firmware, and just use Xposed for any tweaks/mods.
If your trying to use it on AT&T and the radio from the US unlocked RUU should work.

SM-G935P flashed to Verizon

Last summer I successfully flashed an SM-G935P (Sprint) to Verizon. I put it on the shelf without ever trying to use in on Verizon's network. I decided to switch to it from my S6 the other day. Before I did anything else I ran all system updates (via a wireless connection). All went well until I put in my already activated Verizon sim card. I get no coverage at all. Noda. The firmware loaded is G935VVRS8CRK2. Everything in settings =>About Phone looks right. Can anyone shed some light on what I may have done wrong?
P.S. I did try a Sprint sim card and it did show a 3g connection during initial setup. Is something left over from Spring that I need to wipe?
Flashing G935V firmware just converts your firmware to VZW (bootloader, radio, system) and you need to unlock your phone with Sprint still, but if you updated to Update 28 for S7 you can't go back to Sprint's firmware because the Update 28 contains bootloader v9!
TL;DR: you just need to unlock your device via sprint.
Here's a link to sprints unlock thing: https://www.sprint.com/en/legal/unlocking-your-sprint-device.html
The only thing is this, when I insert my Verizon sim card I am not prompted for an unlock code. Also, Sprint automatically unlocks their devices after ~50 days of active service on an account with good standing. Am I wrong?
Simple yet aggravating
So, the main issue I found after unlocking the Sprint G935P is (and I'm sure this is the problem you're having) you have to manually put in the APN settings to connect to Verizon.
Just Google "Verizon 4G LTE APN settings 2020" and enter what it tells you

S10 + Sprint Unlocked issue

Hi Everyone,
I just bought a brand new s10+ from marketplace. I ran a full imei report and everything is clean & not blacklisted. It was a sprint phone however the provider I use is consumer cellular (uses ATT towers). When I put my sim card in it obviously said invalid sim and request it get unlocked. I wasnt concerned because I was going to convert it to unlocked anyways via odin like I did my note 9. I reflashed it via odin with the u1 firmware. However the same thing is happening it keeps saying invalid sim and the button for mobile operators is not showing. I have a tmobile sim card and if I put that in it works fine. Being though tmobile and sprint are the same thats why it works fine. I also have a ATT sim card, If i put that in I get the same invalid sim message. So it still appears to be locked somehow. Only sprint / t mobile sim works. I thought by reflashing to unlocked it would unlock the phone sim.
Just to be clear the phone is brand new and never was attached to any account.
Any ideas? I dont know what to do here.
Thanks!!
As I understand, phones that are locked to a network are not just software branded... also the phones hardware ID. So flashing a generic firmware is not enough. You need to get the phone unlocked from the phone's original operator
I found out what I had to do. I had to use a remote unlock service to remove the software lock on the phone. Its fine now. Thanks
