Prl downgrade - EVO 4G Q&A, Help & Troubleshooting

I just finished resetting my data settings and updated my prl and profile. Thing is, I now have prl 60680 and its killing my battery. Does anyone know of a way to downgrade the prl. 60679 was perfect for me.

PRL does not kill your battery. All it is, is the updated info on the towers in your area. I really don't think it's much more than a database.

Check to see if your uptime and awake are the same. If they are, you have a wakelock issue and as HipKat stated, it is NOT because of the PRL.

I'm on aosp but its showing my device sleeps good. I guess I should try messing with different radio combos.

You can try downgrading only the PRI and see if that helps.

It was my nv. I had to downgrade it to 1.77 003. Thanks for the suggestions. Mod please close or delete.

I was gonna suggest that. Seems like that, the 2.15 radio and the 1.90 PRI are the best combo of radios for the wakelock issue.
There's a whole thread about it in the dev section

[Q] flashing cyn mod 7 with new radio

i like have no signal while Im at work,in hosptial. With Myn i had signal power lots of place. Ever since I went ginger happy i get like no data connection at all. so like no texting while im at work. I wanna flash the latest radio but is wondering if a good move or bad. Holla back and letme know...
also where can i find the latest radio zip.
thxs
Yes, of course you should update your radio. Especially because it can help with speed issues. Update with the zips on this thread
You flash any of them through your recovery, but I wouldn't update your HBoot which is why it's not in the combo.
It wont let me download radio 215. Why is that. From Cal's site

Oops didnt mean the thanks, but o well. Those downloads are working fine, your best bet is to use the combo one on the very top.

Has radio 2.15 been a success for anyone here or in other words nightmares.
Sent to XDA by the mind of an EvoKing. LoL
I have had no problems with the 2.15 radio.
Now signal bars drop down to all white. More drop calls as well. Should I have just dl the whole string update?

Flashed the radios. Seemed to help. But, I has to have the worst connection on the planet, so anything would have helped.

Download the zip, backup your current rom in recovery. Then wipe cache and dalvik cache, flash the zip file.
I did it all with no problem just don't flash the kernel

Can these be flashed with Recovery 3.0 or should we downgrade to 2.5?
Flashed on CM7 N87 and all is good!
Updated Kernel
Tiamat 4.0.4, CM7 nightly, RA 2.3
Confirmed all is working after flashing the radio update. Though still 1x in my office building due to interference from the verizon/att tower in the back if the property. Sprint refuses to attach to it, lol
I may stand corrected here, but in order to get the full benefit of the new radios you should update your profile and prl. Yeah, it probably isn't needed necessarily considering the pain if your on an AOSP rom, but a good idea because with the profile update it helps the network recognize that you have the update.

I'm getting a major boost in data connectivity after the radio update. Spots where I'd get no WIMAX before I'm getting decent service.

Question Regarding Radio

I just came from the HTC HD2, and there were many radio updates to flash to the phone. Are there updated radios for the Epic 4G? I'm having network and cellular network connectivity issues, so an update makes sense here...
Not yet. Try going to settings /about phone/ updates and update Profile and PRL

Yeah I've done all that. Still have the issues. Sprint says it's an issue with the phone, but I find that hard to believe.

[Q] One week deep. LOS/Sleepy Radio software or radio based?

I like the hardware but this loss of service thing is annoying.
Has anyone determined if this is a software issue? Sprints network isnt great but my evo 3d fares much better.
Ive read around on the internet and I THOUGHT I read a post that mentioned a user reverting to EG30 which solved his/her problem. Only thing that isnt positive is whether the user reverted to software EG30 or baseband EG30.
Any insight into this issue, how to revert to an earlier software version? Ive tried various radios but not software. I appreciate your time.
I'm having same problem....my evo 3d had no problem with Los but my e4gt is terrible where I live.....I was told to try different modems but I tried FCO7 AND FC14 still the same.

Hmm, what do you mean by "loss of service"?
This is a term used specifically to describe losing service while the phone says it has service...

Ok, maybe that is incorrect.
Just using it, for example sending a tweet or an email, one may send immediately. Then if I choose to refresh or send a second tweet/email right after, the transmission arrows dont light up for a while. Its like the radio is going to sleep way too fast and it takes even longer to wake up and complete the transaction. Enabling/disabling fast dormancy doesnt seem to make a difference.
Edit: under these conditions, I never get the "no signal" icon. Just seems the radio is sleepy
Well I asked around because my signal sucks but I called sprint and they said my area has really good service.....but people told me to try FCO4 and FC14 and FCO7 that might help so I did......nothing helped.
I just looked it says I'm using el29 on my kernal and FCO7 under baseband.......not sure if that helps,ill try to find out more and if it helps ill let you know

If not then manually install a different PRL, so you can connect to closer towers in your area, and don't forget to update profile and prl in settings>about phone> system updates

The only prl that I think would help is the corporate 11115 prl.
Any other suggestions?

Los on this phone is when you have a circle with line thru it the only thing that fixed that was reboot sometimes toggle airplane mode but they fixed that long ago . Now some ics had similar problems but had a lot to do with your signal strength...
