I want to upgrade a US T-Mobile G1 to 2.1. Is the following procedure correct? (Don't need to backup.)
  1. In bootloader flash RC29 DREAIMG.nbh. Reboot.
  2. Type telnetd, install Android Telnet Client and root.
  3. Install recovery-RA-dream-v1.7.0-cyan.img using Telnet Client.
  4. In recovery flash G1-radio-2_22_23_02.zip. Reboot.
  5. In recovery flash spl_1_33_2003.zip. Reboot.
  6. In recovery flash FR-recovery-v1.5.3-CustomMTD_S.zip. Reboot.
  7. In recovery flash signed-SuperE103.zip then flash gapps-mdpi-FRF91-3-signed.zip then flash FR-boot-v1.5.3-CustomMTD_S.zip. Reboot.

Your way will work but I recommend a minor change iif you are using the rc29 method of rooting:
  1. In bootloader flash RC29 DREAIMG.nbh. Reboot.
  2. Type telnetd, install Android Telnet Client and root.
  3. Install recovery-RA-dream-v1.7.0-cyan.img using Telnet Client.
  4. In recovery flash spl_1_33_2003.zip. Reboot. (Will return to recovery)
  5. boot fastboot and flash the 2.x radio (info on my 1.33.2003 post.. and the *.img file is in the g1boot.zip)
  6. while in fastboot wipe so custom mtd works 'fastboot erase system -w' and 'fastboot erase boot'
  7. In recovery flash FR-recovery-v1.5.3-CustomMTD_S.zip. Reboot.
  8. In recovery flash signed-SuperE103.zip then flash gapps-mdpi-FRF91-3-signed.zip then flash FR-boot-v1.5.3-CustomMTD_S.zip. Reboot.

I'm not 100% sure of that gapps package.. just check the super-e page if its correct

Edit: If you don't want to downgrade first look at:

Thanks for the links. What is the advantage of installing radio via fastboot instead of recovery?

Rather than re-iterate see my post here: http://forum.cyanogenmod.com/topic/6...post__p__44790

In short it should be of similar difficulty for you the user and it has slightly less risk (not that there was much risk in flashing a 2.x over a 1.x one in recovery)..

For many scenarios that could brick however: if you flash via fastboot you will likely continue to be able to access fastboot after the flash; thus able to fix the phone.. while if you flash via recovery you get stuck in "boot mode 3" unable to boot anything without JTAG.
