At this point i am ready to buy a code from dc-unlocker. Something in another thread lead me to think that they were going to want an imei number...
As far as my comment about the partial upgrade, these are my notes as towards what I have going on. I’m not a total noob, but guess I am just spoiled with how easy the nexus and one plus devices have been.
• Locked BTV-W09
• NRD90M test-key
• Last tried to install C128350 with Firmware Finder
• fastboot oem unlock doesn’t work (I have no code). The Huawei website doesn’t seem interesting in giving me a code (check values); I have no IEMI to enter, yet am on EMUI5.
• Can only power up from dead battery on ac (usb starts and then starts shutting down, once into Android)
• Can power down from Android, but it immediately tries to power itself back on, and it doesn’t seemt to work – hangs on “Powered by Android/Huawei MediaPad” screen.
• any fastboot commands, beyond devices or reboot fail.
• Can’t seem to boot into bootloader from/with adb or recovery screen
• Huawei Firmware Finder (Team MT) mostly works, but since it doesn’t either shutdown or start correctly, whatever I try doesn’t install.
• Three key combo sequence to install from sdcard doesn’t appear to work
• reset of tablet does not work – it goes to restart, which doesn’t work.
• HiSuite software, says everything is fine.
• Can get into recovery screen, says Phone locked FRC unlocked (oem unlock in developer options is enabled)
• can adb
I’m at a bit of loss for things to try. I think the test-key problem means I need to flash the hw data update that goes along with the release, but I don’t have anyway that I know of to do that.
