You can now flash new radios on an S-ON HTC EVO 4G LTE

6a00d83451c9ec69e20168e9441304970c 800wi - for some reason we don't have an alt tag hereWith EVOs prior to the HTC EVO 4G LTE, the main benefit of S-OFF was the ability to flash radios without reverting to stock and doing an over the air update. But even then, you were stuck going forward and could not revert to an older radio in case the newer one did not work so well. Luckily, Captain Throwback has delivered a method for the HTC EVO 4G LTE which circumvents the S-ON restrictions to recovery mode and allows any versions of the radios to be flashed directly from recovery.

The two notable times I can remember needing S-OFF to change radios were once on the OG EVO, when a radio update was eating my battery alive and I had to jump back a version, and more recently on the HTC EVO 3D, when I wanted to try a ROM that had a different baseband and had to go forward.

With S-ON/unlocked providing no functional differences to S-OFF, the only barrier to a completely free phone is the requirement to use to unlock the bootloader. As HTCDev states, this may invalidate the warranty, and many people believe that once you’re on the list, getting warranty work could potentially be an issue. (This should not be any issue for Sprint users, as we know what the official Sprint repair policies are.)

There appears to be no performance benefit to flashing either of the radios available for the EVO 4G LTE, and with flashing radios you always have the potential for something to go screwy, so I’m going to hold off playing on radio flashing until such time as there is a reason to, but it’s nice to know the method is there when we eventually need it.

  • does anyone ever actually go through HTC directly for support? If so, I would like to know why, when you can easily either get it swapped or repaired by sprint.

      Many people do. Keep in mind the EVO line is not Sprint-exclusive. The GSM versions of the phone run on different networks.

      GSM also allows for you to port your phone from carrier to carrier. So any of the GSM EVOs potentially could be being supported by nobody/require warranty repair by HTC.

  • Hey Paul,
    Thanks for info and sorry this is slightly off subject. But wasn’t there a review on a “all in one” method to root and automatically do the leg work from HTC dev unlock method.? I’ve already done the one click root so I’m good there. However the HTC portion is lil more confusing. I tried on my newly replaced og Evo4g but couldn’t figure it out. Now with the LTE I’d like to again be fully unlocked.
    Thanks for any info.

  • cool thanks. yes i already used the one-click method you guys posted weeks back. (worked like a charm). However i was curious about the htc unlock. thanks again . ill give it a go

  • I had to go through HTC for a warranty repair once. I did not have insurance and had an early 3D that was afflicted with the phantom screen tap bug. The phone was unlocked using HTC’s official unlocker and I was in their “could invalidate your warranty” database. Sorry to disappoint all the tinfoil hat folks, but they honored the warranty and send me a refurb without a hassle. I promptly HTC unlocked the new phone and did a nandroid restore of my previous stock & rooted ROM.

  • thanks i ran the process and am currently running a restore on titanium pro. Your the best Paul thanks for all the help and valuable info!

  • From the brief reading I did following the links you provided it seems they’ve also figured out how to make flashable kernels for S-off EVO LTEs and One X’s… Nice!

    HTC always seems to leave in just enough loopholes to appease enthusiasts, even with the official HTCDev unlock method so many people complain about.

    Either that or they’re incompetent and can’t seem to lock down a device as tightly as Moto has in the past… I choose to believe the former tho. :p
