Dangers of downgrading after installing GPS radio (and a little on signing)

And if that is not the case, we will end up with units with "dirty" radio ROM area? Thus causing possible incompatibilities with official ROM releases and/or end up with bricks?

I am further wondering, if sprint techs will be able to detect this when and if we have to turn in a faulty unit for repair or exchange..

The official release of the Sprint Touch GPS ROM will more than likely be a 3.xx radio. The titan's radio is a 3.35, so the touch should be in the same range, who knows maybe itll even be the 3.37 radio customized for sprint.

To answer your second question, yes the sprint tech's will almost certainly be able to detect this. Especially when they see that the bootloader screen says 2.31 ImCokeMan. Also the radio version can easily be detected in the EPST.ink menu.

Ok, this is definitely not good... I have one that needs work, repair or exchange... The screen does not align correctly, even after a screen alignment it would crap out after a few minutes... Any suggestions as to what to do..? I currently have a GPS rom on it...

Thanks...

1) Why is installing the Titan GPS radio a bad idea, but its "ok" to install the Alltel radio? The Titan radio (3.35) is sprint's radio, so shouldnt that be more compatible with my Sprint Touch than the Alltell 3.37 radio (i currently have 3.37 on my Sprint Touch and am considering "downgrading" to 3.35 because of all of the rave reviews about the increase in GPS performance).

2) Is the 3.35 radio the Titan radio you say to avoid installing? Thank you.

Radios ARE device specific! I am speaking from a physical device level on all of this. Do not flash Titan radios on a Vogue! If i felt the phones were the same i'd make a model ID patch in the SPL as well, but they are different devices! As for the carrier, once you have your device as SuperCID which the unlocker simulates there is no physical limitation to using a radio from another carrier.

Now on the other hand the carriers do have customizations and they may not be set up correctly when using a new radio/rom, but that doesn't make the device more prone to unrecoverable device bricking which are the dangers i'm speaking of.

Nice to have someone more "reputable" acknowledge/confirm this as I got tired of being treated like a n00b when I made that claim/statement!

Speaking of which, is the WiFi access in the Titan part of the radio, or is there a separate abstraction layer?

I went from the Titan radio back to 3.37. I was having lots of issues making outgoing calls with 3.35.

This reminds me, of not so long ago, our conversation about downgrading... where i remember saying you'd admit reluctantly that it's not "impossible" but highly not recommended. Even that being said, with some of the more recent threads that are around, i completely understand why you started this

What steps did you take to go back to 3.37 from 3.35, if you don't mind. Thanks.

While I did get the radio changed, I think I'll let someone else give the step-by-step directions on how to do it. My process involved having to flash the stock ROM via sd card to bring my Touch back from the dead.

so does this mean as long as you stay on the touch radio, you'll be alright? I am asking this because this give me the impression that once I flash the radio, any radio, I won't be able to go back to stock at all given all stock roms at this moment are non-gps 1.xx versions.

And if in 6 months, those new gps-enabled roms are everywhere, there's really no need to go back to the 1.xx radios, this "problem" will not be any problem anymore, am I correct?

I think you'll be fine. If it's not working already, whats the worst that can happen. You brick your phone and you use your insurance to get a new one. And if you don't have insurance, call in and get some today.
