"Re-Partition any MTK6589 Phone, Without A PC! (More /Data Storage!)"
When I reboot my phone, it stucks at logo screen.
What I've done trying to fix it:
1. Enter the recovery mode; it's a stock recovery (Android system recovery <3e>); wipe data/factory reset, wipe cache partition.
Result: still stuck at logo when rebooting.
2. Flash a stock ROM in recovery mode.
Result: Update aborted. In the log file, it says "failed to mount /cache (No such file or directory)" detailed in attached file. The stock rom I used is for ZTE LEO S1, while my phone is DTAC LION HD which is a house brand of my phone carrier. So, there may be a problem of ROM signing.
3. I installed "Minimal ADB and Fastboot" and "ZTE_Android_Driver", and run "adb devices" command.
Result: There is nothing under " List of devices attached", so I assume adb cannot see my phone. In Windows' Device Manager, it shows "Portable Devices" and lists drive I:\ and K:\ under it.
In summary, My phone is rooted. I might have damaged partition /data and /cache which causes the bootloop. I can still enter stock recovery mode. I have a stock ROM, but may not be properly signed.
Please suggest me on what I can do next.
