Root How to flash radios (from recovery) with up-to-date radio links

You are correct. Good idea on the new thread. You're keeping this place super organized :D

Theres really no reason to wait for full S-off. Everything we need to do can be done with S-ON and HTC Dev unlocked
 
I never thought that I'd see it this easy, but I'll just repeat what I said a few years ago about the Evo dev community - HTC keeps trying to build a better mousetrap with their bootloader and they're not up against mice, they're up against junkyard dogs.
 
Thanks for getting this posted up guys!! I only had 1 day at home this weekend, didn't get as much accomplished as I'd hoped.

We'll never see S-OFF on this device now, no need. Believe me the good Cap'n will find a way to remove the watermark too. He did it on the OG, he'll do it again. ;)

The Cap'n doesn't have any issues with us posting his OP's either. Really cool dood there, glad he's a part of the community. :)

EDIT: I stand corrected, S-OFF is here. LOL :)
 
Okay, I'm going to be a noob. Flashing radios is new to me (I'm coming from an Optimus S).
What exactly does flashing one of these radios do? I assume it's not the same as a PRL update.
Is it mandatory to flash the latest one with the new rooted stock ROM?
Which order - radio then update, vice versa, or does it matter?
Can I flash a new radio on an older ROM?
Sorry for all the questions!

It seems like we were able to mix and match without issues on the OG EVO, but I'll be playing it safe and sticking with what it was designed to run with.

At launch of the first Evo, devs stressed those rules, I've always gone by them. The old XDA Evo wiki page used to make it clear which radios went with which roms, but that got re-done and well - became less that fully useful. :(
 
I guess i need it spelled out for me, sorry about that.

I never accept an OTA since i have been rooted, seen too many problems others have had.

After the Devs have incorporated this OTA into their roms and kernels, it will be ok to flash the new radios it has as well?

If one were to flash the radio w/o that incorporation, will it break anything or just not be effective?

I read in here about how it used to be generally understood not to mix radios with older versions but it hasn't been stressed or followed on the old Evo. I have flashed various radios soon after they hit the street in hopes of improving my reception. I don't know if i was helping myself or just messing things up?

I do know that problems while flashing radios is one way to brick our old phones, would that hold true here as well?

If you recall the early days of the Evo, devs were not ok with mixing and matching.

I suspect that was because of matching to kernel changes, but I can't back that up.

In theory, if the hooks in don't change and the exchange structures don't change, you can mix and match them. How we'd know that without someone guinea pigging it, I couldn't say.

My personal bias is pretty clear - short of a defective radio update from the source, go with what the HTC engineers figured out. Anyway, that's just me.

I imagine that anything is possible with flashing and would caution to make sure that your phone is charged and that you check md5 sums before flashing anything, especially radios.

Unless bad reports hit in force, I will be using the new radios with any 1.22 based rom that I go with.

No clue what happens when we get to aosp roms.
 
That definitely has logic to it.

unfortunately, i do not recall the early evo days. I had just upgraded to a Moment, and a little while later, upgraded my daughter to the Evo, but i have only had one for a year. That's how it goes sometimes... :D

And thanks again for the info!
 
I pulled out the new radio thread and tossed it in the sticky, but it turns out over at mikmik, they have the on-going collection. Hmmmmm....

PS - title change here, sticky updated for it.
 
Anyone else update ONLY the radio out of this recent update?


Just curious. I did and have had some minor issues....and battery life took a nose dive

I have and it seems the opposite for me, less drain from wonky signal when I was on the web.
 
I stopped updating radios a while back I notice I have never improved my signal with them nor have they had any noticeable affect on my OG EVO. I'm not sure if this is the Same with the LTE but I'm in an area where its not offered anyways. I also know that the sure'est way to brick your device is to have something go wrong while updating such radio's.
 
New phone, new network, new rules.

The only dev at XDA saying to mix and match radios is the one with a thread with mysterious bugs.

Your mileage may vary, but I would caution all to remember the early Evo days where rom and radio mixmatching was definitely frowned upon.

And yes, at the very least, check md5 sums before flashing anything, especially radios.
 
I hope it doesn't mess with the battery life. I didn't even know you could just update the radios.

I got the firmware zip that was in the MeanRom thread, it is a dl from CapT. There were a number of things there that it seemed to update, I don't know how to find out what all they were.

Being on the new 1.4 rom too, I am not going to be able to tell, if the battery life starts going down, if it is the rom or the update.
 
Non-root users are reporting better battery life because of the update.

If yours suffers, I wouldn't blame these radios.

Last I checked, CapThrowback was using the mikmik site as his radio source, so you should be fine.

I'm picky about sending people there because unlike other payloads on XDA, those are radios, whereas some others are handing out radios AND a new hboot - the last thing you want!

This is pretty much where I stand on the issue If I do download and update a radio then it is from the HTC engineers still I think I need a bit more than new phone new rules to determine if these are a necessity :)

I hear you but the problem you and I both have is that they're skimpy on giving us lowly users a real changelog to know.

FWIW, I tend to always look at the non-root user OTA reports - always have. Whenever I see them talking up better service and such, that's a cinch for me. Also, sometimes we get some insider info that specific things happened in the radios to solve issues or to accommodate the new network.

In any case, I can pretty much assure of this, with the Network Vision changes and whatever they do in their learning curve on the towers, it's not if but rather when you'll be flashing radios.

Wait a second - you're on the 1.4 MeanRom, so you have the new kernel (from the 1.22 OTA).

If you flashed only the radios, you're on the old kernel.

Bet me the kernel and radios don't tie together somehow. ;)
 
What i have been hearing him say is that the radios do have some good reports.

That he thinks you should match the radios to roms/kernels based upon the ota that provided them, as 1.4 is.

And that due to Sprint changing stuff around, we most likely will be needing to flash new radios, at least at some point.

So no, if you are on 1.4, that rom is built on the ota and should accommodate the radios.

If I understood him correctly... :p
