Months ago I upgraded my metro PCS huawei ascend from a 2.1 to 2.2 froyo (the metro PCS version) through wifi.(Phone is rooted) Now I'd like to upgrade to 2.3 CM7 gingerbread. Im really impressed with the added features,UI, etc. I've seen different ROM versions out there and many installation how-to's. I already installed 2 different CM7 roms on my sd card (no PC, using turbo downloader from market). I don't know which one of these will run smooth and is compatible with my device→ CM7-Ascend-05142011 ,, I don't wanna end up doing more harm then good since I don't have a PC or USB cable. Can someone please give me step by step instructions on how to upgrade my (metro pcs) huawei ascend m860 to 2.3 gingerbread straight from my phone (with the right ROM), from what I've heard it can be done I, just really need it to work right the first time.. I know many of you are knowledgeable in this area. Thank you
