[Q] how to get fastboot working
My phone is not recogniser in fastboot by the PC.
I have a HTC One UL (Intl.) S-OFF, CID HTC_032, ARHD 30.6, Hboot1.44.0000.
As my phone does not vibrate any more, I tried to return to stock to take it service.
I followed this guide http://forum.xda-developers.com/show....php?t=2541082
I downgraded Hboot1.44.0000. and I LOCKED and removet TAMPERED my bootloader with this tool http://www.htc1guru.com/dld/1-29-401-12_hboot_1-44-zip/
I downloaded this EXE RUU RUU_M7_UL_JB_50_HTC_Europe_1.28.401.7_Radio_4A.13. 3231.27_10.31.1131.05_release_310878_signed
Started it, rebooted my phone, yet my computer will not recognise the phone in fastboot-usb. Unknown USB Device (Device Failed Enumeration)
ADB still works. My rom is usable.
Can someone guide me how to get fastboot working, or how to flash another HBOOT, and then get to stock.
I have to be 100% stock to take it in service and when i start my phone a red warning appears.
Could i be able at least to get the command fastboot oem writesecureflag 3, to be S-ON and tahe it in service?
Thanks in advance,
