[One (M8) Q&A, Help & Troubleshooting] Xcutz:
I've flashed the RUU from H10 and the LTE was working fine when using H9 & H10.

Now I don't have any more LTE (on AT&T, with an AT&T variant converted to GPE).

I tried:

-the "cellular network settings" and switch from 2G, 3G & LTE: no success

-typing "*#*#4636#*#*" in the dialer, then going into the options (by default "WCDMA preferred" was selected, I was able to select GSM but couldn't select LTE Only nor GMS/LTE or most of the other options, by clicking on them it didn't do anything and kept "WCDMA preferred".

-Just flashed again the firmware "M8_GPe_Firmware_6.0_MRA58K.H6_5.07.1700.6_0p6bimg.zip"

-Then re-flashed RUU "RUU-HTC_One_M8_GPe_Marshmallow-6.0_MRA58K.H6_5.07.1700.6_0p6bdiag.zip" successfully

-Cleaned cache & reboot

I have an AT&T variant

CID GOOGL001

Model 0P6B120

Firmware:

HBOOT-3.19.0.000

Radio-1.23.2133311491.A13G

S-OFF

I noticed some things while flashing:

1)

FAIL90 hboot pre-update! please flush image again immediately

FAILED (remote: 90 hboot pre-update! please flush image again immediately)

For "hboot-preupdate" response, restart the same procedure for device FA46DWM03625...
