Just to add to this. I had MIUI and CM7 etc working perfectly on my phone for a while. I went back to Froyo H57 because of some of the sensor issues and GPS taking forever to connect (I needed to use GPS and MIUI just failed horribly). Now since going back to H57 Dfgas did a H57GB thats based on AOSP and I decided to try it. Now I also have no data with any AOSP Roms. I have been trying for several days to get this working.
I have done a total format gone back to 2.1 Eclair then Froyo then any GB AOSP ROM. all results are the same no data on the AOSP ROMS only.
I can get data for a short time after placing a call with the phone, but it will lose it right after. Going back to stock and using any touchwiz/stock froyo based ROM the Data works just fine.
For some reason the phone isnt even communicating with the AAA Data server with AOSP ROMS, doesn't even initiate a data sessions so the AAA wont assign an IP Address to the phone.
The weird thing is AOSP ROM WERE working for me until I tried them again this week. I have since given up and just using Froyo stock based ROMS. I may revisit this again in a couple of weeks, but I have no idea what is different or why it doesnt work for me anymore..
Just wanted to say you are NOT alone in this.. Thats all
Oh and for the record, I have tried all the stuff mentioned in this Thread, RFS reformatted, EXT Reformatted. Even did some stuff with Dfgas on IRC yesterday. I have also done some stuff to the account (as I am a service tech) Got someone to deactivate, resend to switch and resend to AAA, Reactivate etc, but no dice. Still no data on JUST AOSP Roms.
Really bizarre issue indeed.
