I have stock ICS 403 active with HBOOT 1.53.0007 and unlocked resp. rooted my Evo ed using the HTC method.
I have also installed 4ext recovery using fastboot tool and tried to flash Cool-ICS-v18-EvoG.zip after backup,factory/data reset, wipe cache and davlik.
But I have got message E:can't open /sdcard/Cool-ICS-v18-EvoG.zip (bad).
I made a restore and downloaded again the zip-file as I thout it might be corrupted. Resul the same.
Then I googled and found that I can flash a ICS based rom also using the original recovery (CWM). I reflashed recovery again with original cwm recovery image.
Performed the same steps: Backup, factry reset, wipe cache and davlik.
But also there the zip-file could not be opened.
What might be wrong?
Could you please give me a hint. Thanks in advance.
With kind regards,
