Galaxy S4 SPH-L720 (jfltespr) (Sprint) GSM Use not available!

[IzumiSenaSora]

Hi i bought a Galaxy S4 (it was a dream phone in past of mine).

I got a Galaxy S4 which on back it says it was GT-i9505!
But in bootloader it says SPH-L720!
Then i tried to flash GT-i9505 stock rom it failed!
Then i tried SPH-L720 it worked!

Now after installing DivestOS 11 no GSM Sim use available!
But i am outside of US so no CDMA network here!
After inserting SIM it says my SIM Card name but No Service!

Can someone help me how i can use my SIM outside US with GSM Network?

The device might be locked to Sprint by IMEI.

that is very weird, I don't understand why it would do that

Maybe properties get generated while installation from bootloader information instead of hardcoded in a file?

Edit: I tried to update it via "Settings/System Updater" after reboot into recovery it shows "Error!" Then rebooted into system.

That means even if i try to update via Settings it still checks if it JFLTE XX or not.

Can you add JFLTE SPR support in "updater-script" file in JFLTE XX build please

[SkewedZeppelin]

I don't think this can be easily done.

How about adding jfltespr in TARGET_OTA_ASSERT_DEVICE Variable LineageOS Repo Link

TARGET_OTA_ASSERT_DEVICE := jflte,jfltecan,jfltetmo,jfltexx,jgedlte

Replace it To this via sed command

TARGET_OTA_ASSERT_DEVICE := jflte,jfltecan,jfltespr,jfltetmo,jfltexx,jgedlte
