Dear Sir,

I can see that you used the version 1.9.4B version of the management software.And i would like to ask you to updade to our latest version. Right now it is 1.9.4F. In this 1.9.4F we included an additional check after erase to confirm that erase was performed good - it's called blank cleck. For more info read our sticked thread about it : http://forum.gsmhosting.com/vbb/f101...-9-4f-2549284/.


Now about fixing your machine, if the erase was intrerupted by the mac, then when HDBOX wrote to chip, the content got mixed, and image inside is not good. I see you made a back before clicking write, that is VERY good. Just download 1.9.4F and do like this:
1-Click detect SPI, see if the chip is detected properly, click it 3-5 times,
2-Click open file - load the backup you saved,
3-Now you can either unlock what you need, or you can just directly restart it to see if its starting or not. And then Unlock it.



After good erase/write, the mac still have an issue and does not start, then is time to perform an NVRAM / PRAM reset, and sometimes even an SMC reset on the machine. Here is a helping link: https://www.macworld.com/article/288...m-and-smc.html
