[HD2 Android NAND Development] nickj:
Data And MMS connection issues...

First off, I'd like to thank tytung for all the work that has gone into this great project and all the others that contribute their time and energy in keeping it ever moving forward. Thanks to all. I'd also state at the outset I'm no genius at any of this and have attempted to learn as I go based on the work of people far smarter than myself, so please bear with me. As of about 2 weeks ago I began to experience similar data and mms issues as Down8 and tytung described/discussed in post #'s 6733,6734,6735 and #6746.

I had been running version 2.8 Nand with no apparent issues (and loving it!) for quite awhile until attempting to connect to the web one evening and getting a "no connection/timeout" error. I assumed it was a TMO network issue (West Atlanta) and didn't give it another thought. Since that time however, the issue hasn't corrected itself and I'm hoping someone might be able to offer some guidance. I first attempted a restore from a CWM backup but with no change. I also performed a clean install of V2.8 with no impact. I have since performed a task29 and followed the install instuctions from post 1 as recommended, and installed V3.0 hoping this would solve the issue. No joy, still the same. My current setup is: TMO HD2 HSPL: 2.08.HSPL, Radio: Leo_RADIO_2.15.50.14, Bootloader: MAGLDR 1.13, Bootloader: cLK 1.4.0.1, Recovery: ClockworkMod Recovery 3.2.0.0. As Down8 described, I too can make and receive calls and use wifi without any issues. When attempting to go online either via browser (native and Skyfire) or through market most often it will attempt for quite awhile and eventually give an error with unable to connect. Here's what I've discovered in trying to isolate the cause. If I check the option to "use only 2g networks" this issue disappears and everything (Data and MMS) functions properly as it had been, only more slowly needless to say. I can uncheck "use only 2g network" and if I immediately attempt to go online it will work for maybe a minute but will then encounter same timeout/no connection issue again. In researching this, I see where the real Nexus had similar issues at launch but I wasn't able to determine any "fixes" that changed my current situation and don't know that any "fixes" would apply on the HD2 at any rate. Running *#*#4636#*#* I ran a ping test while having the phone unchecked for "2g network only", I get these results as I type this (further test may/will change some results) and occassionally I do get a "pass" showing a good connection:

Ok, if you're still reading this I applaud you and apologize for the long post. Hopefully this is just an isolated event and I still wonder/suspect if in fact it isn't a TMO issue versus anything to do with this build. At any rate, hopefully someone might have suggestions as to how to proceed. Sad to say, even if I never resolve this issue, I'd rather continue to use this ROM using only EDGE versus ever returning back to WinMo 6.5.3 so in any event, I still feel like I've came out much better for the trade. Thanks again tytung.

Stumped,
