RADIO VERSION

The Qualcomm MSM6275 chipset is found on Hermes, Trinity and Breeze devices.

If radio version ends in "1" it means GPS is enabled in this radio, if it ends in "0" it means is disabled. Example:

Radio 1.21.31.10 ==> GPS is disabled

Radio 1.22.01.01 ==> GPS is enabled

To see NMEA data you can use the command "at@startgps" in GSM AT Command interpreter. To stop receiving NMEA data use "at@stopgps". It is possible to flash a GPS enabled radio from Trinity on Hermes, but Hermes hardware seems to lack either the antenna or the RF amplifier (or both) and it is not possible to use the MSM6275 as internal GPS on Hermes. See related thread for more info on this.

HTC_BOOT

This is the radio bootloader, do not confuse with normal bootloader (SPL).

Until now there are three radio bootloader versions found inside hermes radio (GSM.nb): 1.0106, 1.0107 and 1.0108

The last 4 digits of the radio bootloader version is returned by radio bootloader command "rversion".

These are the known differences between them:

1.0106 -- still has command 'rrbmc' to read back the memory content

1.0107 -- command 'rrbmc' does not work anymore, but it has been replaced by command 'rdpram' with the same syntax.

1.0108 -- this was first seen in Softbank X01HT post december 2nd devices (radio 1.14) and is also included in some trinity radios. The peculiarities of this radio bootloader version are explained here:

If you have a radio with HTC_BOOT 1.0108 on your device, you can't use extracted radio ROMs: This means you will not be able to flash radios in NBF format with MaUpgrade_NoID.exe anymore, you'll allways need to flash them in signed NBH format (ie: full ROM upgrade).

If you have a radio with HTC_BOOT 1.0108 on your device and flash a full ROM upgrade in NBH format, the radio will not be flashed unless your SPL version is 1.09.

If you have a radio with HTC_BOOT 1.0108 on your device and flash a full ROM upgrade in NBH format with SPL-1.09 on your device, your radio will be changed to the radio contained in the NBH file, HOWEVER the radio bootloader will stay the same HTC_BOOT 1.0108.

The same, explained in other words:

If you have a radio with HTC_BOOT 1.0108 (for example softbank x01ht 1.14 radio) and want to flash radio 1.21.31.10 on your device:

Upgrade your SPL to version 1.09, either by flashing a full rom containing SPL 1.09 or by flashing only this SPL with MFG bootloader.

Flash a full ROM containing 1.21.31.10 (or your desired) radio version, for example jasjam 1.31 rom. This will put radio 1.21.31.10 on your device, but HTC_BOOT will be 1.0108 even if the radio 1.21.31.10 has HTC_BOOT 1.0107.

Flash MFG bootloader again and flash extrom and OS "manually" from MFG.

Results after this:

Radio 1.21 will be back on your device, but HTC_BOOT 0108 will stay instead of being the original HTC_BOOT found on radio 1.21 (HTC_BOOT 0107). This means you will not be able to flash radios in NBF format with MaUpgrade_NoID.exe anymore, you'll allways need to flash them in signed NBH format.

Recommendation:

Don't flash any HTC_BOOT 0108 radio on your deivce if you plan to test Trinity's GPS enabled radios on Hermes, because you'll loose the ability to flash radios in NBF.

There are 2 trinity GPS enabled radios:

- 1.29 with HTC_BOOT 0108

- 1.22 with HTC_BOOT 0107

If you want to test, flash the 1.22, otherwise when you flash a new full hermes ROM in NBH you will keep the HTC_BOOT 0108 and will never be able to flash a Trinity radio on Hermes again.
