I will explain you my case:
What i want to do is flash this model (E715) with E710 flash. I just thought it would be safer to read flash before, cause if something went wrong, I would be able to write it again.
Anyway, I get the same error (1st boot: failed) even when I try to WRITE flash. This means I canīt read nor write flash to this Samsung phone using UFS. (Just for record, I have already successfully flashed Sony Ericsson and Nokia phones, but this is the first Samsung one and Iīm having trouble.)
SO, what would be the natural procedure to follow?? Ask ufs support for help. Well, I tried contacting them using www-ufsx-com contact page, but got no response. Also searched www-ufsxsupport-com for a support e-mail, but there isn't. (And my reseler can't help, cause he don't have experience flashing Samsung phones also.) You said you can't see which part of support is bad. Well this part is bad. If I got similar problem with Martech, I can write to support-martech.pl and they will try to help me.
But, look, I'm not saying everything is bad. In fact UFS got nice, complete and up to date flash files site. And box is of great use... Ok, that's it.
Thing is I still have this samsung e715 flashing problem and If you l be so kind to help me, I would really aprecciate.
