[Q] Will an RUU downgrade a radio?

I want to run RUU_IncredibleC_Verizon_WWE_1.22.605.0_Radio_1.00.03.04.06_release_161493_NoDriver.exe
But before I do, will it downgrade my 2.15 radio to 1.0? Will it put back on the stock .77 HBOOT?

yea it will

Ok, so if I first turn S-OFF back to S-ON, then I can run the above named RUU, and I'll totally be back to stock (radio, recovery, hboot, OS)??? Am I missing anything?

Leave S-OFF.

Def leave s-off if you want to get root back right away.

The phone is going back to Verizon (it won't charge the battery), so I will be putting S-ON before it gets sent back. Do I do that before or after running the RUU?

Root, s-on, RUU

Unrooting

Hi!
My phone broke and now I want to try to get it fixed with warranty. I'm not sure if warranty still is available if I use root so I want to unroot.
I have read that all I need to do is flash the RUU, but which one? http://forum.xda-developers.com/showthread.php?t=824357
And what will flashing it do? Will it remove CWM and everything else I was using to root? I remember that I flashed radio 2 times, had S-OFF and E-ON.
And then I will simply run System Update? Because it seems that RUU are firmwares that phones are shipped with.

yea, just flash a RUU.
Make sure you install the original RUU for the type of your DHD (i.e. WWE, Voda,T-Mobile...)
and if your phone is S-OFF, make it S-ON - S-OFF / S-ON GUIDE (guide for S-ON is at the end of the 1st post). Go into bootloader and make sure you have S-ON
--your recovery will be restored to original HTC recovery

Oh, but which RUU I need to flash? I remember I needed to do a downgrade and I think it was 1.72.405.3, not the R2, but I'm not sure.

Well, when you had your phone, was it branded?
if so, you need to find a brand-specific RUU.
If not, then WWE RUU is fine.
i would suggest the 1.32 FW (because S-ON requires temproot from Visionary+), then follow the guide to S-ON

What about radio? I have flashed the leaked gingerbread radio, wouldn't they be able to see that I have flashed a newer radio? Or the RUU flashes radio also?

RUU flashes radio too. But after flashing the RUU have a look into the bootloader, the device might still be S-Off. For S-On you need to root again and Use the easy radio tool to make S-On again. Then use the RUU again.

It still was S-OFF, but used Visionary and Easy Radio Tool to get S-ON. A brand new phone
Thanks!

Does it work the RUU to flash even if I come from an ext4 ROM (ARHD 5.1.9)?
Or do I need to format first by cwm 3.0.2.6 so that it is ext3 again?

No one any advice?

Unrooting Desire

Hi guys,
Looking to unroot my Desire and sell it.
What's the best way to do this please?
Thanks

Partition sd, then flash RUU

Thanks
Will sort out.

Take a ruu rom and flash it

Is it that simple even if you are s off and are running a custom partition? I was reading that you need a goldcard if you are boot .93 or greater. The unroot guide thread has a lot of comment from people who haven't simple loaded the standard ruu, maybe that's their issue

Yes, its that simple. You only need a goldcard, if you handset is/was branded and you want to run a unbranded RUU.
S-Off doesn't cause problems, except you have flashed one of the new downgrade-proof hboots from alpharev - you can check by booting into bootloader and check the version number. If its version 6.xx you need to flash the downgrader-hboot from alpharev first, then run the RUU, if its version 0.xx, you can just run the RUU.

thanks. I'm selling mine so am about to give this a go. I'm running cm7 partition so was presuming I would need to get the partitions back to stock before doing anything. Just loading the ruu sounds much less hassle.

Nope, the RUU restores it all back to stock

just thought I'd update this for completeness. If you've used a recent version of alpharev you have to flash the downgrader.img before running any ruu as the hboot change is now blocked.

But only protected against ruu and ota, other hboots can be flashed without using the downgrader.

[Q] About flashing back to stock rom

Hi guys, just a few questions.
1) Requirements for warranty is it just unroot it? or do i need S-On for my device?
2) Is it possible for me to use the stock rom i backed up to revert back to stock? and does that means its free to go for warranty after flashing back? Do i really need to use the RUU version stock rom?
Just these questions for the moment.
Any kind souls to help? Thanks alot!

If your device is not bricked, you need both S-On and Unroot.
If you have done Radio S-Off and Root, it is easy, just run an official RUU and you will be back to stock
If you did Eng S-Off... well that complicates things a bit and you have to use Jkoljo tool if you used to achieve Eng S-Off (I don't know about any reversing any other method), just hope you kept your Hboot backup (the one that the tool made) on the root of your SD card.
Hope that helps.

Yup, so i have an eng s-off, radio s-off and rooted device.
Does that means i need to use that Jkoljo tool you mentioned to remove eng s-off and then run an official RUU to get back to stock?
and the hBoot filename is something like this?
"hboot_original.bin"
Thanks alot for the reply here =)

The steps you should do are like this.
1. Run the 1.32 RUU and then Re-root + Radio S-Off
2. Run Jkoljo tool and reverse Eng S-Off
3. Re-Run the 1.32 RUU and you should be back to Stock with Eng S-on and Radio S-On.
PS. if you are using a branded handset you should set back the CID to the correct number (Cannot remember exactly how, but Jkoljo thread should have some info)

Ok. I get it now! Thanks alot! =)
One last question. Branded handset means?

Like carrier branded (aka locked handset). You know like Orange/Vodafone locked DHDs where they have custom RUUs and CIDs.

[Guide] EVO Revert to stock + S-ON after Gingerbread

This took me all day to figure out so I'm making a guide. The 2 Big problems I had were getting the S-on patch to work and the newer Hboot that came with gingerbread refusing to downgrade to an older PC36IMG.zip.
The main reason I wanted to return to stock was for a repair, last time i did everything except s-on and the guy noticed it and black listed my esn.
Make sure you are prepared before you continue! Once you flash your radio your phone wont boot into the OS.
First, you need to flash an older radio for the S-ON patch to even work. I found flashing EVO_Radio_2.15.00.07.28.zip worked best. Do this in your custom recovery
Follow djR3Z's guide to turn S-ON but do not go past step 7!
Download this file I got this off a youtube video for the incredible and replaced the files with their EVO specific counterparts
Open the zip and move flash_image and mtd0.img to your sdk/tools/ folder
boot into your custom recovery and mount /system/
open up a command prompt in your tools folder
(in windows7 hold shift and right click on /tools/ there will be an option to "open command window")
Run the commands in the commands.txt file. FYI you can paste into command prompt with right click.
adb push flash_image /data
adb push mtd0.img /data
adb shell
chmod 777 /data/flash_image
cd /data
flash_image misc mtd0.img
exit
adb reboot oem-78

After this you can move your stock PC36IMG.zip to the root of your SD card and reboot into your Hboot Bootloader. If everything was done correctly it should now accept PC36IMG and downgrade to stock.

Great job! Do you think there will be an easier way in the future? I don't think I would be able to do this.

If you run the 3.70 RUU while still s-off, will it replace the hboot with an older version? It seems like it should, but I'm confused by the 6.16 hboot.
I haven't actually ran revolutionary, so this is all theory, but I thought unrooting/s-on would work like this:
Run the RUU for 3.70. I don't have much experience with RUUs, but if they don't include radios, you would then need to reflash recovery and downgrade the radio. After reflashing etc, then flash the s-on zip. Then rerun the RUU for 3.70 to get rid of your custom recovery, or run the RUU for 4.24, since once you're s-on you can't downgrade & every RUU will be a downgrade from 6.16 hboot.
Now this may be entirely wrong, but I was just curious if it would work. I've been rooted for a while, and unrooting and s-on would be much easier for me. Even though it sounds like a pain, it still sounds more noob friendly than the version in the OP.
Either way, great job on putting this together. I know that a lot of people are curious about unrooting from revolutionary, so hopefully you've cleared some confusion.

I can't get this step to work, try as I have to get S-ON back, it won't go. Doesn't the Revolutionary HBOOT prevent this from working?
The unrevoked-son zip flashes fine, and says it worked, but I'm still S-OFF. What did you do to get it to work?
@plainjane
HBOOT will not update to an older version. If that were possible, the GB OTA wouldn't have had to be rooted at all, since everyone would've been able to downgrade to a rootable HBOOT version.
It's that fact that makes me wary of this method working at all. Can the steps after the "S-ON" portion be completed (which I assume finds a way to downgrade HBOOT), and then run the S-ON tool & flash the stock PC36IMG? I think that's what I'll try now, since I can't get it working in the order specified here.

You can downgrade via RUU if you're s-off. My suggestion was to run the RUU while still s-off, because s-on won't allow you to downgrade. Or, if the RUU won't replace the bootloader, then flash an older hboot.
Then, if you're still s-off, flash the s-on tool. I don't know if this root method uses unrevoked forever or if it's just an always s-off hboot. I do know that it's a different hboot version.
If anyone has a chance to try to run the 3.70 RUU and see if it downgrades the hboot, I'd like to know. If it doesn't, but the RUU completes, then you should be able to flash recovery and then flash an older hboot - I believe 2.10 is the one that shipped with 3.70. Mine is 2.02, and I never updated to 3.70 (I believe it was 3.30 when I rooted).
Again, it's just a theory. If I get curious enough then I may unroot and update just to try revolutionary and try to unroot again, but I'd rather not get stuck with a horrendously obvious 6.16 hboot that can't be replaced/unrooted if I don't have to.

What I was saying is, at least with the Revolutionary HBOOT (6.16), it will not downgrade, either using the 3.70 Froyo RUU or the 4.24 GB RUU or PC36IMG.zip files flashed through Fastboot. It bypasses the Bootloader update every time.
Have you somehow gotten HBOOT to downgrade while S-OFF?

Hboot 6.16 will not downgrade or flash S-ON currently.
