    I have been running CM7 since September, and I love it. However, I am a bit of a NOOB with ROMs and I think I need some help. I have gotten really unsatisfactory 3G and 4G connectivity. I hardly ever have a good 4G connection, usually it switches to 3G, and quite often either 1x or no data connection at all. I thought it was just the network that really sucked, but I am thinking more and more that it is something with my phone, because I have been around other people on Verizon that have no problem while I do. I am running CM7.1.0 RC1.8, with radio 1.48.00.0817r and kernel 2.6.35.14. Is there a better radio/kernel combination that might help my connection issue? I don't want to change my ROM, I love CM7, I just need a more reliable data connection. I would really appreciate some tips if anyone has any.

    The newest radio is from the 605.9 OTA, and is quite a bit newer than the one you're currently using.

    Its posted here in the all things root section. I'd give that a shot, it seems to be a lot more stable than some of the previous radios.

    Also, there's some newer versions of CM7 available. Maybe try this one? Its the newest version, and is built by a CM7 Dev.

    Thanks for the reply. After I posted this, I found the newer radio for 605.3 and flashed it. 4G wouldn't work at all with that one, so I flashed the old one back and I've actually been getting good connectivity all afternoon. I didn't see there was an even newer one for 605.9, I'll try that one.

    As for the newer CM7 build you showed me, I didn't really understand what that was, because it says it's not a Cyanogen supported release, and it's not in the original Slayher thread either. I don't know who Thundershed is, and wasn't sure if it was a trustworthy ROM. If it's good, I'll give it a try.

    605.9 is the newest radio. Definitely worth a flash.

    There is no official CM release for the Thunderbolt, Slayher just happened to be a CM Dev, and so is Workshed. He maintains the Eris for CM.

    I knew that the CM7 wasn't official, but I didn't realize that the other one you mentioned was the same sort of thing. I never really understood who is who, I thought Slayher was "the guy". Now I understand, thanks!

    By the way, I did upgrade the 605.3 CDMA radio, but left the LTE radio on the older 605.1. I don't know if one has anything to do with the other, but I am getting really good results with this combo on my LTE service. I am getting 6-11Mbps with no outages like I was before. It's only been a day, so I'll try it for awhile before I change anything. I just didn't really know much about the radios and kernels, still don't, but things seem to be okay for now.

    Thanks again and Happy New Year!

    I was having issues with my 3G & 4G until I switched to Liquid ginger 3.2 from CM7, since then my phone connectivity has been perfect.

    I am not trying to say Liquid ginger is better than CM7 since I am also a NOOB in the rooting world, there are experts here who are really good at mixing & matching ROMs, Kernels and Radios to give them the ultimate performance, they are in a better position to say which ROM is the best.

    As a NOOB, Liquid ginger v3.2 out-of-the-box seems to solve all my problems, didn't need to do any tweeking. I suggest you give it a try.

    Thanks for the tip about the newer radio. I just put the 605.9 radio on my TB and I'm getting much better results. Really good on tethering with my iPad too, so that's really good for me!

    i also have these problems, and i have a few questions.

    if i want to try different kernels, will that effect my connectivity in any way?

    and most importantly, i can just flash i radio like i would a rom or kernel? i dont want to brick :p

    From a post by El Presidente - http://androidforums.com/faqs/443075-root-terminology.html

    "The kernel is the OS at its most basic format and acts as the bridge between Android and the phones hardware. It looks after things like voltages, power consumption, WiFi Strength (to a certain degree), CPU speed and the scheduler (see above). It's also one of the first things the bootloader kicks in to life after your handset is switched on. A decent kernel can make a massive difference to performance and battery life."

    Flashing a radio has to be done in hboot.

    1. Download the radio to your phone - Rename the file to PG05IMG if not already done so.
    2. Place it in the root directory of your phone (It's the same directory where the "Android", "Download" and other folders live).
    3. Download AFV (Android File Verifier) from the market and check the MD5 checksum with the one listed from your download source (Important step, do not skip). If they don't match, then download again.
    4. Once a match is verified, power off phone.
    5. Hold down power and volume down until the hboot screen appears.
    6. Wait - Hboot will check for the PM05IMG file. It will then prompt you if you want to update - Select yes.
    7. Be patient - Let the phone update - It may seem to stop at times but it is still working. The phone will prompt you to reboot when it is done.
    8. Once your phone has rebooted - Delete the PG05IMG file - It is no longer needed and it will get in the way of getting to hboot in the future if you leave it there.
    9. Enjoy your new radio
