Slow 3G and/or 4G speeds? - Epic 4G General

Ever since I started playing with the leaked Froyo builds I noticed that my 3G and 4G speeds were incredibly slow (never going over 100Kbps on uploads or downloads). After flashing back and forth 4G started working better but 3G was still disgraceful.
No matter which how many times I used Odin to go back and forth between DI18 and DK28 I kept getting the same results. So a few days ago I decided to flash the oldest DG27 build and use OTA updates to go back to DI18. Well I think that fixed everything because now 3G works perfectly.
Same thing happened to me with the accelerometer and compass. I used the /system/bin/sensorcalibutil_yamaha command to reset the sensors and now the phone is back to perfection.
I'm just typing this up because I've seen people complaining about problems like this every once in a while. Hope this helps anyone out.

[Q] Are any roms going to increase 3 g speed?

i was running the super D rom a few months back and i was able to stream netflix and youtube on my computer from wireless tether. even the Cyanogen 6 rom i was running was doing fine , till just a few days ago, it got worse and worse.
I just flashed the new CM6-FroyoRedux-v1.5-32b-blk and I'm having major issues with my 3g speeds still, i don't know if my towers changed recently or what the issue maybe i live in downtown Portland,
any other roms you'd recommend for good 3g speed? Or any roms that still are based off of froyo? I'm downloading round 8-10 .
any recommendations would be very very helpful.
i haven't overclocked or tried anything like that. everything is basically default.
Thank you.

Update to 2.2 worth it.

Guys I have nero v5 installed and I want to install the stock samsung vibrant froyo. Is it stable and how do I install the update. I backed up my stock 2.1 rom and am ready to restore to 2.1. Do I idyll 2.2 through kies or what
download kies mini and update through there
You install it through Odin. Personally I don't think its worth the upgrade from Nero unless you like the stock look. I came from Nero v5 to try out this rom and notice that my wifi is much slower, when wifi is off my bars say 3g but internet browsing feels like its on edge, and I can barely get a gps lock. On Nero I always get a lock no matter where I am. Of course apps load slightly slower, but that's not my biggest issue with the rom.

I get consistently over 3.8mbps dow now. Thats almost 1 mbps morw than my average before the update. I wrote in another thread wifi reception was better as well.
I think youre just expweienving some placebo effect. Happens a lot to people who use lag fixes and stuff.

I was wondering the exact same thing. Im running Nero v5 and was debating weather to revert back to stock and do the 2.2 update
It is very stable for me, upgraded from stock 2.1 am pleased my gps never worked anyways so meh.
I upgraded from stock ji6 so that's the only rom I have to compare with. It was a nail-biting experience since kies wouldn't pick up my phone thanks to Tmobile leaving out the minor detail that USB debugging had to be enabled. Midway during the upgrade process kies crapped out with an error saying upgrade failed. Phone would only boot into emergency recovery and was luckily able to use the kies recovery option to finish. Phew! I've flashed phones before but they were always spares so I didn't care if they bricked or not - this is my first time flashing my main phone.
Ka6 is a definite improvement over ji6. The one thing I noticed immediately is lag is gone!! ji6 used to go from 3g to edge for no apparent reason, now it stays on 3g. Haven't noticed any difference in the transfer speeds in 3g or wifi, seems about the same. Built-in wifi and usb tethering is nice, and much improved copy paste. Different colors, GPS still is meh. I was using my Garmin for 2 years before I got this phone so I never really cared about the GPS. Aside from built-in flash all the other changes appear to be cosmetic. Media scanner seems quicker.
If you're still on stock ji6 the upgrade to froyo is definitely worth. If you're running a custom rom like Nero, Axura etc. I guess you should stay with it. You upgraded to a custom rom because you obviously put a custom rom on your phone because you didn't like stock!

Going Back to 2.2

After beating on 2.3 on my stock N1 for almost a week I've gone back to 2.2.1 on my MyTouch 4g.
Continuing problems with 2.3:
Battery usage, even after following all the tips on this site (network selection, etc.)
Juice Defender doesn't seem to be turning off wireless when it should
Lack of trackball wake
Swype KB doesn't seem to be as intelligent as the one that comes with the MT4g
Inconsistent performance with ExchangeSync
Advantages of 2.3:
None apparent to me. I don't load up with apps so haven't seen any storage shortages that are apparently corrected by 2.3
Besides the MT4g has physical buttons.
Maybe things will settle down in a couple of months. But I'm liking the MT4g more and more the more I use the N1.
thanks for your story
Battery life for me was /really/ terrible. I too was considering rolling back.
Then I looked it fresh and wondered what was happening.
I'd been leaving the wireless on usually, knowing that it'd stop itself. This lately update seems to fix that so it's on more often.
Turning it off manually now, I'm back to pre-update power usage it appears.
+1 here; my whole company exchange account (mail, agenda) went lost since upgrade GB; no way to set it up properly again!
N1, stock, unrooted, OTA froyo -> GB
how many threads do we now need for people not liking 2.3?
I've just gone back to a custom rom, after losing root with update..
decided to go back mainly due to a bug where the screen kept disappearing..
i never tried a gb rom as i dont want to update my radio..

Flashing a new radio should be the least of your worries, if your not worried about flashing a rom than the radio is a cakewalk!

There is no reason you can't leave the one you have and still have GB as far as I know.

Do agree with you. Exchange Sync not working as it should anymore. Stop syncing after a couple of emails. Never happen with 2.2.2
Dang

Install "Wheres my power droid". It's free in the market.
I also went back. I went to stock with root of course, partitioned sd card and installed Link2sd. Gingerbread also killed battery and I need trackball wake. Will go back to 2.3.3 soon.

4G latency on EC05

I have run a few tests, and ever since installing EC05 I have noticed that my latency on 4G is way better. I used to see it around 250, and now it is in the 90 to 120 range. It also wakes up faster than it did before. I actually like using 4G now, lol. Anyone else notice that their latency and wake up is better?

That's due to the updated modem firmware mostly. They performed several fixes on that front and overall should be getting a lot better performance not just on 4G but 3G as well.

When ACS makes a ROM from EC05 then I'll update. Are you using stock or Bonsai?
The EC05 update and the modem overall fixed all the problems everyone was seeing. Check every problem people were complaining about and you will see that Sprint fixed all of the problems with the EC05 update. The Modem is nearly perfected in the EC05 update as well.
Even when acs does release the new version it may not include the modem just like bonsai. So just odin it now its worth it. 3g drain is really low now.

[Q] EF02 Reviews

What does everyone think of EF02?
I have EC05 rooted and have had occasional issues with visual voicemail (says cant play until I restart the device), texts not coming through properly, and misc other issues. I was considering going to a ROM such as bonsai, but thought maybe EF02 would be better since it's close to a stock release.
I use my phone for business and look for stability and battery life primarily with performance and eye candy ranked third or fourth. Thanks ahead of time for the help.

There are some kinks to work out. GPS is pretty iffy, and some apps don't work, for some reason. Still, it's clear the future is bright, cause I can't wait for something already this snappy to get rfs replaced, overclocked, and tweaked to hell like the froyo roms.
As for your other issues, I ported my number to google voice, so they handle all my texting/voicemail. No regrets so far, other than maybe that I can't use handcent anymore. People get my texts instantly too. My brother was at a ball game I was watching on tv once and was getting my texts along the lines of "He was safe!" so quickly after the plays he jokingly asked me if the TV was somehow ahead of live action.
One issue I'm having with EF02 is that I've lost the default shortcuts on the toolbar. All I have is Applications...
Anybody know how to get them back?

I'm taking aa i3 for a run. But for a worry free xperience do the following..
Odin eb13.
Get gps lock.
Root.
Flash ef02. Set it up to ur liking.
Odin ec05 modem.
If you use titanium backup then restore only app not data!

I've had no issues at all with EF02 w/EF10 modem. The only GPS issue I ever have is using check in on Facebook but the GPS locks fast so I think it's the Facebook app which in my opinion is pure garbage. It sucks on my girlfriends phone too and some of my coworkers have problems with the app as well.
I'm getting excellent performance. With 105+ apps installed, I'm getting 2500 on quadrant. I'm going to test gps in a few. All apps seem to be working.. i had some that didn't but i just uninstalled then reinstalled from market and it worked. Running i3 with GPS fix and chris41g rotation lag fix.

I ended up going back to EC05 for SRF 1.2, but thats out of personal preference for the SRF rom. In my experience with EF02, it was very good. Fast for RFS, pretty good battery life, and all around mostly pretty stable... seems Samsung/Sprint are pretty close to a final/official build to me.
I am using EF02 with EF10 modem and it has worked perfectly so far. GPS works better than ever. All of my apps work. And I have had none of the wierd EC05 force closing with the 3 vibrates. It works great for me and can't wait for the official to drop.
I have been using EF02 for a while (AR i2) and everything has been very good, I had some strange issues with the GPS at first but now everything is working fine.
I get 12-15 hours with moderate use, not nearly as good as some of the Froyo roms but worth it because of Skype/Netflix... With the EF10 modem I got about half that, so I went back to the EF02 modem and everything is great.
I thought ef02 aa i3 was pretty good. Memory issues pushed me back to froyo. The leak didn't seem to clear memory correctly and used too much. other than that and gps issues at first I was actually happy with it. All in all not to bad. These froyo roms seem to be to polished to continue on a leak rom though.
