Hello,
This update in Nougat/version 7 went very badly:
1) the OTA update was a failure. After this update, the phone kept rebooting.
2) I upgraded the version "UMIDIGI_Z.V7.01_20170601_update.zip" with SP Flash Tool in "Firmware Upgrade" mode. Same problem, the phone kept rebooting.
3) I made this same update, this time in "Download Only" mode. As expected, I lost my Ids. I have set them with your "SN Write Tool" page. No problem, except I lost my serial number (it became : 0123456789abcdef). There, the OS worked, but was very unstable. Frequent restarts, and I even lost the sound!
4) I downloaded "rom-20170225_g15v97_kw_u8_4m.rar" and flashed it with SP Flash Tools. This installation proved very stable. I then accepted the OTA update one by one. Everything went well until version 7.01_20170601. After version is installed, the phone reboots randomly.
Currently, I have remained in this state, I stay in version 7.01_20170601. The phone is usable. But it reboots without reason, usually when you need to go into the Wifi options, or 3G / 4G.
I look forward to an update that corrects this instability related to everything that is radio. Thanks in advance. |
