I have been dealing with this for over a month. Nothing works. UBreakIFix was my last resort for a software flash. Literally, nothing. Every single hour I get a notification that my firmware is trying to update, followed by Internal Error 407. I am beyond frustrated. As far as updating the UICC, when I hit ‘UICC unlock” it immediately begins trying to do a firmware update. There is no notice saying SIM Restricted…. I have an unlocked phone.
Same here, T-M with a s10 Plus, unlocked. This is way too frustrating and I'm definitely looking to get rid of my phone at this point.
This is crazy I am having the same issue over a month. S 10 with Tmobile, I had the phone for 16 months wondering if I can return it
They need to do it asap, I've already been looking into new phones (clearly NOT samsung)....i can't take this any longer. The error 407's are happening more frequently and driving me insane. While I'm using my GPS, watching YouTube, etc. I'm over it, as I'm sure everyone is. Good job, samsung.
Hi, I see you tried UICC unlock and it seems like it didn't work. Did you have these instructions? They worked for me. Hopefully they can help. I understand the annoyance
Thank you for your attempt to help. Unfortunately that won't work on my phone. I never get a "sim restricted" message, it just goes straight into trying to update my firmware. Which fails each and every time.
