How can I completely downgrade and revert back?

[xxza]

I am currently using JD's rom and Titan's 3.35 radio. I want to have a completely downgrade and revert back so I can use sprint's official new rom in the future.

Could someone tell me how to do that? Thanks.

Btw, what's sprint touch's current officical rom version and radio version?

Thanks. This post had this section:

PLEASE NOTE: It has been said that GPS radios and Non-GPS radios are very different. Flashing from the original 1.13 Radio to a 3xx Radio will write a TOTALLY new Radio to your device and reverting back to the OEM 1.12 Radio will not completely remove the new 3xx radio.

So my questions is: Now I am having the titan 3.35 radio. How could I completely revert back to the OEM 1.12 radio? If I can not, will this affect my future upgrade of sprint official new rom?

Thanks.

Go over to the ppckitchen site and click on the chat button ... perhaps Colonel, GGuruUSA or ImCoKeMaN will be available to give you an answer based on their personal and low-level experience with the process.

Thanks.

I'm a little nervous about this as well. That being said, I do have faith in the PPCGeeks community and something will get figured out.

I figure even if we can not upgrade the hacked rom to the sprint official rom directly, someone at this board will make a rom for us to upgrade...

I asked IMCokeman the same thing and he basically told me that it would be probably be safe to install from the 2.31 bootloader. (it wont get overwritten) I thought we might have to load the .4 bootloader which should allowthe custom bootloader to be overwritten. I wouldnt mess with it now however. Who knows how long we will be waiting for the sprint rom to come out

As far as flashing a the OFFICIAL OEM Sprint ROM Upgrade when it comes out, I think I will not upgrade to it just yet. I personally am using the 2.31.coke unlocker and have the Titan Radio flashed and am using Ghettofreeryder's ROM flashed to my device. I think that, given the complex method of upgrading to the Titan Radio, I will wait for someone to figure out what needs to be done to complete the Sprint upgrade successfully.

Honestly, what I will probably do is figure out a way to flash the Core OS only and not the new Radio or SPL. This should avoid any real problems at all with the upgrade.

Problem with that is the likely chance that Sprint might be using a different radio that will be specifically designed for gps and rev a and such.

It's difficult to answer a question such as "what will work in the future" because the future has yet to arrive. It is very unlikely, however, that you will need to revert your radio to stock pre-gps, to then upgrade it.
