[SOLVED] Help Needed for Updating to 4.4.2: "htc_fastboot.exe has stopped working"
Hi Developers
I have a SIM-unlocked AT&T HTC One (32GB, completely stock, Android 4.3, Sense 5, modelid: PN0712000, cidnum: CWS__001, Hboot 1.55.0000, baseband: 4T.20.3218.13, S-ON, LOCKED bootloader). I have been trying to update the OS to 4.4.2 but I failed every time. Here's a list of what I did so far:
1. I tried the RUU_M7_UL_K44_SENSE55_MR_Cingular_US_4.18.502.7_R10_Radio_4T.24.3218.09_10.26.1718.01L_release_356565_signed_2_2.exe. It starts OK but when it reaches 5%, an error "htc_fastboot.exe has stopped working" appears and the process is terminated. I have tried this on three different PCs (all with Windows 7 and proper drivers installed, adb and fastboot working) and all of them showed the same error. Suprisingly, RUU_M7_UL_JB43_SENSE50_MR_Cingular_US_3.17.502.3_Radio_4A.19.3263.13_10.38j.1157.04_release_334235_signed_2.exe runs just fine and I can reflash the 4.3 using it without any trouble.
2. I tried flashing the OTA update.zip via stock recovery by copying the update.zip on the phone storage, rebooting into recovery and selecting "apply from phone storage". It didn't work either. I failed to catch the error message showed on the recovery screen as it was very quick to exit recovery and start the phone in normal mode.
3. I extracted the rom.zip from the RUU.exe and tried to flash the rom.zip from fastboot using "fastboot flash zip rom.zip". It also starts to work but after some time (around 220 seconds) it shows "12 signature verification failed" error.
Could anyone please let me know how can I update my OS to 4.4.2? Thanks in advance.
