Does anybody have much experience with different modems? I have had pretty spotty connection every since I switched to the newest rom. The signal says full and all icons indicate data is connected properly, but things aren't loading at all or are very slow. I'm not sure if a different modem would make a difference or not.
Yes. I believe modems are designed for different regions in mind. There was one reliable modem from the GB Era (KI4?). It worked well for me in the SF Bay ARea whereas newer ones like KL1 (which has a good reputation in general) and LPH kept dropping data left and right. I'm not sure if it was an RIL (in which case not modem) issue with my ROM at the moment, but given it was Gingerbread CM7, I think the RIL was not the issue.
KI4 worked well in SF Bay ARea but REFUSEd to give me 3G in Detroit, MI. My Nexus S did fine on 3G and got decent speeds. I finally flashed LPQ modem and I got 3G. Wasted 40% of battery all morning trying to get KI4 to work and it was a bust.
But I assume you're not on the international SGS2, so I can't really help you with modems. Entropy512 who does a lot of dev work for the SGS2 phones recommends the older modems. I think he mentioned KH7 or something which is what he uses as the newer ones are crap.
While I think modems DO make a difference, I don't think there's as much difference between them as people make it out to be. PEople claim battery life significantly changes, but I think that's within use pattern. Or furthermore if one particular modem su cks with 3G, the battery use is from trying to connect to 3G.
My success with mass restores using Titanium Backup is essentially 0%. I only restore selected apps as needed.
very surprised. I've had 100% success essentially. You have to do Restore missing apps & system data. And it's more an issue when you jump from ROM to ROM as they have special apps and kernel tweaking apps that are rom specific. However, with small changes, I've been ok, like flashing CM to a non CM ROM, you make sure you take out the CM apps. I used to wipe every few nightlies and do a mass restore with TB. Every few months I'd wipe my whole ROM and restore selected apps only and install the rest for a clean slate (kinda like reformatting a HD and reinstalling windows).
The only time I had horrible luck was going from GB to ICS, but everyone knows you have to be careful. Just restore apps. System data restore crossing different OS versions will screw you up. I had to use SMS Backup & Restore to move texts over.
