LG G5 H830T 32GB T-Mobile 4G LTE Android Smartphone (New other) [ebay.com]
New other (see details): A new, unused item with absolutely no signs of wear. The item may be missing the original packaging, or in the original packaging but not sealed. The item may be a factory second or a new, unused item with defects. See the seller's listing for full details and description of any imperfections.
Phone's seal was opened and resealed for unlocking purposes
Android pay might not work. Sim card not included.
Seems like the seller flashed custom rom to unlock it. From the previous threads looks like it is possible to restore to stock rom to get warranty and official updates, but will lose the unlock.
