Radio version 1.27.00.00 is available for the Hermes!
This radio has HTC_BOOT 0107, so it is "safe" to upgrade. We have it in two flavours:
- Shipped upgrade (signed NBH file) containing only the radio, valid for:
- HERM300 T-Mobile devices with CID starting with "T-MOB1"
- SuperCID devices
- NOTE: SuperCID (unlocked) devices with HTC_BOOT 0108 (for example SoftBank X01HT post Dec-2nd) must use bootloader SPL-1.09 to flash this radio!
- Extracted upgrade (NBF file) valid for:
- Hermes devices with bootloader 1.04 and HTC_BOOT (radio bootloader) version 0107.
- screen will show "Upgrade Radio Stack Please wait........."
- after finishing flashing radio (about 15 min) you will see an "Upgrade Error", but the radio ROM will be flashed anyway.
For more information see the extracted radio wiki page and information about radio ROMs.
As always, upgrade at your own risk!
