I have no idea what i didn't to. No thing i didn't try. It won't turn on, it won't go in recovery.
Always black screen. I connect it to PC with both volume Up and Down pressed and i see it's in FDU mode, some sort of Diagnostic i beleve. That gave me some hope that it is not actually dead.
I tried this Thread. Since TPT, Clockwork, Fastboot, Win updater are no good for this state of phone i jumped to Method #5. All went good until 5.4 (Restore channel1.nvm to your phone). That was finished, just every single step as the @hedgepigdaniel said.
After finishing that, pull out battery and the phone will go into CWM recovery. The thing is that my phone won't do that. It remains with black screen.
About the phone:
probably USB Debugging is Off
Volume Up, Menu, Power = vibrates, back button goes red, screen on but plain black and stays like that
Volume Down, Power = same result
Volume Up, Power = same result
just Power = same result
USB connection ( i have all the drivers)
Both Up and Down volume + USB = FDU Mode
Down + USB = Unknown Device under Universal serial Bus Controllers
Power + USB = Always installing drivers, i see ZTE Composite ADB Interface under ADB Interface
Just USB = Unknown devide under Universal serial Bus Controllers
So from Daniel's thread i downloaded that flasher, with both volumes pressed i see my phone in that program is in Download mode.
If i start that BATCH file for recovery it just keeps "waiting for device".
ZTE Terminal online upgrade (PC Suite) doesn't know what is the device connected.
So, now what? It is cheap phone, but the price here is 60% of my paycheck. So it isn't that cheap for me. To make things worse, it's not my phone.
Now i take it as a challenge, i flashed, bricked and unbricked a lot of phones. About 10 Skates, few SE X8 and X10, Samsungs, HTCs, etc. and never had this problem.
EDIT: I also tried Sales_DL_P743_Hungary_V1.00.00 and the App see the phone but i get error that the firmwares are different
