  1. hii frnd, m in jus in way to upgrade my g1 to froyo, so plz do tell me 2 simple things, 1) is computer tethering working fine after upgrade 2) does it hav any serious bugs, bcoz i use to g1 everyday…

    plz reply

  2. hi, i have a t-mobile g1. i downloaded the exterm foryo rom and G.apps. when i go in recovery mode. come a message E:can’t open cache/data/recovery command…so if you can help me please??

    • i did that for ages, you want to check you haven’t renamed your update ‘update.zip’ as it already has a hidden .zip suffix, thus making the file update.zip.zip and unrecognisable to the recovery mode

      this fixed my problem in windows 7,hope you have the same circumstances/luck

  3. this version sux.. no sound, very laggy, slow and unstable crashes all the time on G1. get the official release from cyanogenmod forum, much smoother.
