[Q] Downgrade to 1.29 stock Rom and stock radio downgrade

Hi Guys,
First of all I want to thank all people doing a great work, be it ROM development, testing or answering queries. I love to read a lot and I had leared many things from here.
I searched a lot on this great forum but could not find specific answer for my question. My level of expertise in mobile technology can be labelled as above average.
My query, Currently I have CDMA rooted phone running on DamageControl 2.05, Radio version : 2.42.00.03.10, Hboot : 1.41.0000.
I want to downgrade to stock ROM (1.29.651.1) and stock Radio(version I dont know). So,
1. is it safe to run the RUU(1.29.651.1.) with current Hboot?
2.If not, what should be the Hboot version and how to downgrade to that specific version.
3. I know its not possible, but can a Nandroid backup be used in case something goes wrong?
Thanks for all for your valuable time and really appreciate if someone could help me out.

Depending on what OS version was on your phone before you rooted will determine if you can RUU back. You can only RUU back to the version that was on there when you rooted. So if you had 1.29 and rooted then you can run the 1.29 RUU, otherwise you will need to run either 1.56 or 2.27. I know that with the 1.56 RUU it is hit and miss on having problems. If you do you get an error and freeze your phone from loading Android.
Here is the 1.29 RUU > Sprint 1.29 RUU
Here is the 1.56 RUU > Sprint RUU 1.56
And here is the thread for the 110 error that has happened when running the 1.56 RUU > 110 Error fix
I do not accept responsibility for bricking your phone. Proceed at your own risk.

Thanks a lot !!
The phone came with 1.56 version. Can you tell me if I use RUU, my radio image also goes back to stock one? ( I had never used RUU before, usually I updated to various ROM's with recovery).
Sorry for all the questions but I want to do think before doing rather than doing and repenting.

Need a little help on S-OFF

So I just picked up this Hero and was wondering the process to getting it to S-OFF. I'm on radio 2.42.02.10.29 and it is 2.1 Update 1. So my question is does anyone have the correct RUU so that I can use unrevoked?

So I know what to do but I just need the RUU and I don't know which one.
1. Root
2. Flash recovery
3. Flash RUU with older radio
4. Then able to S-OFF

[Q] about firmware and soff

my htcone is soff(by revone) and unlock(by htcdev)
now I have some questions:
1.if I update firmware to 2.24.401.1(hboot1.54),can I Reverting to S-ON and Lock the device use revone?
2.if I update firmware to 2.24.401.1(hboot1.54),can I downgrade Hboot by flashing a 4.1.2 RUU?
3.is there any change/deferent between 2.24.401.1 and 1.29 firmware when I use a 4.2.2 rom?

With the s-off you can do all what do you want

even with S-off after I updated hboot to 1.54 I couldn't flash an RUU with a 1.44 hboot. I got mainver error.
The way to get around this is to manually flash the downgraded Hboot then run the RUU.
You can also it seem flash the 2.17 firmware zip found here http://forum.xda-developers.com/showthread.php?t=2183023&page=500
and that will allow you to flash a downgraded RUU.

Related question, when browsing the different threads in the One Android Development forums I've come across the specific instructions to install the latest 2.24.709.1 ver firmware multiple times but never thought about doing the upgrade at the time. Now that I want to do it, I've been scouring the threads for those instructions and cannot find them, go figure. Can anyone point me out to one of those helpful links? Thanks
I just switched my phone to S-OFF, that's a requirement, right?

Looking for the best way to upgrade my radio.

My phone is on HBOOT 1.44 and Radio 1.00.20.0315. I am currently s-ON running CM 10.1. What's the best way to get my radio upgraded to the latest? Should I RUU and update to the latest OTA? If so what RUU matches my HBOOT? Or is it better to get S-Off and flash the radio seperately?

definitely do not upgrade hboot. best thing u could do is s-off and then u can flash any radio u want anytime! I have flashed all three this week to test, sprint is upgrading towers in phx area and signal is awful! im s-off hboot 1.44. s-off for sure!!!:good:
