I used flash tool to try to install recovery on my Lenovo A750.
I used DA_PL.bin instead of MTK_AllInOne_DA.bin as download agent.
Now when the phone is turned off, it is not recognized (no MT65xx), and I cannot use the flash tool again. Beside this the phone works fine including 'regular' USB connection.

I think the solution would be to re-install DSP_BL. As I cannot use the flash tool my plan is creating the following zip file:

Code:
- DSP_BL
- dir: META_INF
  - dir: com
    - dir: google
      - dir: android
        - update-binary
        - updates-script
DSP_BL - taken from a750_s148_120428_cybermaus_v0.rar
update-binary - taken from A750_S306_120530_cybermaus_ICS_V1.3
updates-script is as follows:

Code:
run_program("/sbin/busybox", "mount", "/system");
assert(package_extract_file("DSP_BL", "/tmp/DSP_BL"),
       write_raw_image("/tmp/DSP_BL", "DSP_BL"),
       delete("/tmp/DSP_BL"));
unmount("/system");
  • Do you think it will work?
  • Do I need to add the files CERT.RSA, CRT.SF and MANIFEST.MF - or can I ommit them?

Thanks
