Still seeing old carriers boot logo

[Android Central Question]

I purchased a Galaxy note 8 from Verizon years ago. After being with Verizon for a year I switched to TMobile to save some money and I brought my Verizon note 8 with me. I used the note 8 on TMobile for another year then I switched back to Verizon and got the pixel 4xl. I sold my old note 8 to a friend who was using straight talk as his carrier. The TMobile boot screen still pops up and he still get messages from T-Mobile and he doesn't have data when he is talking on the phone. Is there a way to fix this? The phone is unlocked and paid off. TMobile says they don't know how to get their stuff off the phone. Also I feel like they are messing with my data. I can't receive pictures unless connected to WiFi Any help is much appreciated.

Setup all files, confused what to do after hit Start,
since it mentions turning phone off and booting into a diff mode.

Just want to got from Spectrum UI7 file to T-Mobile UI1 firmware.

Download that firmware to pc from Frija then use latest Odin

It's the shutting off and going to bootloader that confuses me.
So this simple I can just run odin?

You need to put in download mode which usually is volume down and power button same time

Thanks, backing up now.

Didn't work, odin showed Pass, get notice on boot up, still Spectrum, blocked update.
Wiped phone. Trying now to restore backup.
Next step is to contact Spectrum and found out why an unlocked phone is so mucked up.

Its subsidize carrier's sim , you need Verizon/Att/TMB sim to see the boot logo change, otherwise need to flash unlocked firmware

Thanks as usual, have T-Mo SIM, connected and working, just will not change anything.

No problem, if you want go to the unlocked firmware

 

[DLewis13]

Checked firmware version, did change to UI1, but Spectrum has locked something in.
Will have to contact them, firmware is T-Mobile version now.
Thanks!

The U1 firmware is unlocked , shouldn't show any carr bloat or logo

Warning on boot up after update, too fast to read. Did see something couldn't be changed. Spectrum has something locked, even Settings Connections show Spectrum, even though I am connected to T-mobile.
