These are all the Actions ACU7515 official firmwares, complete with source code and everything. I have no idea how to assemble/build them and flash to the device though.
Code:
s75_release_v9.1.51nodrm_070215.rar
s75_release_v9.1.51drm_070215.rar
ACU7515_9_1_51_NODRM_20070329.rar
ACU7515_9_1_51_DRM_20070329.rar
ACU7515_p10_9_1_52_NODRM_20070518.rar
ACU7515_P10_9_1_52_DRM_20070601.rar
ACU7515_P10_9_1_52_nodrm_E版IC录音补丁_0816.rar
ACU7515_P10_9_1_52_nodrm_2ce_patch_0724.rar
ACU7515_P10_9_1_53_nodrm_20070820.rar
They're ~12M each so I'll only download them by request (from Actions server).

If you can get the part # of the display I may be able to find the correct driver for it. If U disk mode functioning, that means the firmware compatible with the CPU but display driver is wrong.
