When I unlock my LG V40 ThinQ from my TMobile account, it says "IMEI not in T-mobile system",
but this is definitely a Tmobile device with all the Tmob locked apps and Tmobile boot logo and music etc...Its model number is LM-V405TA (same as LG v40 ThinQ sold by TMobile).
I purchased the LG V40 ThinQ from Amazon.
The issue is same as being reported on https://community.t-mobile.com/other-devices-11/how-to-unlock-tmobile-lg-v40-purchased-on-amazon-15026 .
Can you unlock my LG V40 ThinQ?
