I have a cloned UFS3 box with HWK that was working with ufs suite 3.03. I used a software to upgrade to 2.6.7 and after that the DCTx sayes BOX_AUTH_ERROR and others saying "Selected Device, not Compatible with Software". I tried every firmware that I could find and also reverted to 2.5 and used "UFS3 Tools 2.69b" but results are same. Seems they are working only for original boxes. with DCTx Tools 1.3j when I push connect it only beeps after checking the box and shows nothing. I checked other boxes atmega on the box(with changing the ft232's serial)it's working.so it's the firmware problem inside atmega. With "HWK Replacer V 3.03.001" " Code: Updating started... > Device: UFS3 SarasSoft, S/N: 71*** - opened. > Entered to BOOT... >>> 62 CF > Features: 00000001 > Section 1F: 00C7 > SN = 71*** (0x11***) > UFS fw CRC: 0x5FA6401A > Please update your... > Operation aborted > Device closed. and says Code: You need update your UFS before to continue You can see this message only if: - Checksum of your UFS firmware is not correct - UFS firmware was patched - Very Old firmware - ...(i am very lazy to make more tests) PS: you can use UFS3Tool to update your box Any HELP, Thanks in advance.
