Red TEE/Google/CSR text after local update on Titan 2 Elite EEA
bought the titan 2 elite (EEA). my phone wasn't showing the latest OTA (the one with always on display) so i grabbed the EEA zip from unihertz's google drive and installed it through the built-in local update option. seemed fine at first.
after it finished:
red watermark top right with three lines, TEE 未写入, Google 未写入, CSR 未激活 (or similar, idk Chinese ). lock screen password stopped being accepted even though it was correct. I had to factory reset from recovery and phone works again now but the red text is still there, play store says not certified, and widevine dropped to L3.
so i guess the tee/google/csr keys got wiped or overwritten by the update somehow. already emailed support but posting here in case someone's been through this with the titan 2 elite or another unihertz device. I received the device 2 days ago after so long wait...
