Sorry to bother you about a very simple problem that I can't fix.
My son's ZTE Racer (Australian) decided not to boot past the green Android screen. He doesn't think he did anything odd to cause this.
I've tried lots of suggestions from this site and all I can get to work is to put it into FTM mode and then it appears under the Windows (7) drivers as "ZTE Handset Diagnostic Interface(DFU) (COM3)"
I looked at and downloaded all sorts of ROMS and fastboot-windows.exe and adb-windows.exe as suggested by RacerBoy at http://android.modac...very-for-racer/ but as this phone has not been rooted or modified in any way the ADB drivers do not load.
I downloaded an unlocking program to my PC that correctly identified the phone and if I just let it boot normally (without Vol+ or Vol-) then connect to the computer I see a modem device which in diagnostic mode identified the IMEI etc, so the phone is working to some extent despite only the Android robot visible on the screen (which then goes to the TELSTRA logo and freezes).
I have downloaded a TELSTRA ROM file found elsewhere in these forums (TELSTRA_P726TV1.0.0B12-update_signed.zip) - this looks like a full filesystem dump.
Just to restate: this is a completely unmodified phone so Developer Debugging was not turned on, hence the ADB drivers do not work. Nearly everything on this site seems to be about rooted phones with extra things done including Developer Debugging enabled. That is not the case with this phone.
Surely there is some way to fix the phone from FTM/DFU mode only? Or what other programs/roms/action do I need to get/take to recover to factory default or (better yet) to recover to a bootable phone, maybe even without losing data?
Despite my searching on this site this critical thing seems to be missing: how to unbrick/reflash a virginal (unrooted) phone from only FTM/DFU mode. I assume that's exactly what FTM mode is for though - so how do you do it?
BTW it's ok if all data is lost.
Thanks for any help - exact links/instructions would be excellent too!
