[Q] Is it possible to get APX/NVFlash working on the Lenovo IdeaTab A2109?
I've recently purchased a Lenovo IdeaTab A2109 Tegra 3 running 4.1.1 (build A2109_A411_03_13_121126_UK) running stock but with the bootloader unlocked via fastboot.
Last weekend I read about APX/NVFlash which (subject to the backup) gives my device a true bootrom recovery to allow me to restore my device in the case of a brick (handy for if I mess around with custom roms).
So far I've tried using both Windows 8 (with Nvidia generic drivers) and Linux Mint 15 (in a VM) but both have ended in failure producing the following errors:
Windows 8) "Unknown Device Found"
Linux) "Nvflash v1.5.66719 started
rcm version 0X4
Command send failed (usb write failed)"
Two theories I have right now are 1) I'm missing something e.g. firmware.bin, key, etc. or 2) NVFlash is incompatible with my tablet but the problem is I can only find information/specific software for other tablets e.g. Asus TF.
Are there any suggestions for what I can try to get this working? I am able to get temporary root access via CWM and ADB if I need to get anything off the device.
