Just a quick warning, recently a number of new accounts have been targeting Honor 20, Honor 20 Pro, and Honor View 20 owners by sending them unsolicited DMs offering to purchase their phone or the build.prop* file for more than double the original value of the device. THIS IS A SCAM. The user is likely intending to use the phone to claim certain in-game promotional items without actually paying. If you engage with them, one of two things may happen:
- They will insist that you send your phone to them first before they pay, but once they receive your phone they never pay up.
- They will pay you, but then use PayPal to force a chargeback and reclaim their payment even if you legitimately send them the phone.
Also, offering to trade phones is against the XDA Forum Rules, clause 7.
Remember, if it sounds too good to be true, it probably is a scam.
* PS. With regards to why people are so interested in the build.prop file, at some point there may have been a rumour that the file contained unique device serial numbers that could be used to spoof someone's device and claim promotional items without their consent. However, this appeared to be a false claim because the build.prop only contains system configurations and hardware model numbers, neither of which can be used for AppGallery redemptions. Sadly, it doesn't seem to have stopped these people from continually begging for the file. You also need root access to read/overwrite this file so if anyone tells you that they need your file to "repair" theirs, it's likely a lie.
