I currently have HBoot 2.02 on my phone.
Rooted with Unrevoked 3.32 (so it has Unrevoked Forever on it)
I don't know if upgrading the HBoot is necessary or recomended, but if i want to upgrade to v2.10 do i have to UNroot first, or can i just flash it via .zip through Recovery???
Just flash it. Make sure that you have the latest from sprint.
I would HIGHLY recommend not updating your Hboot. There is NO reason to and it often causes a lot of issues.

I wasn't sure about the answer to this question, so I thought I'd just go to Q&A and ask. I searched and didn't find anything on this specifically. I'm a bit worried about using the latest RUU since the whole 2.02 HBoot thing (though I'm not sure if it would update older phones to that version). I was wondering if I'd be able to use the recovery to flash an early rooted rom and from there use an RUU and unroot it to that earlier version.
Sorry if that doesn't make a whole lot of sense, I'm just wondering if I can trick the RUU into letting me install an old version. A botched unrooting left me with the 0.93 hboot instead of my usual .76 eng hboot.
I don't think that this will work for ya, you need to downgrade your hboot. From my experiences by downgrading my hboot i was able to flash older ruu files.

Oh well, I'll just flash the latest PC36IMG.ZIP. I found it on the 2.02 hboot thread. It doesn't really matter, I only need to unroot this thing long enough to have Sprint accept it. It's been rebooting so much lately that I can barely use it for longer than 30 minutes. This was my last resort after wiping repeatedly, changing SD cards and other things.
just remember to flash the Unrevoked S-On tool too.
Hi,
Coming from HTC Hero running VillainROM 1.7 it did not take long before my DHD was rooted. Did Radio S-OFF; wasn't quite ready for the ENG. I thought I'd flash the radio but that did not happen without ENG. So my strategy is to have a backup of the current ROM, do the OTA and then revert to my backup via Clockwork.
I hope my strategy is OK.... but where is the OTA??
Thor
There are some problems with your strategy buddy.
If you flash the ota you will loose the clockworkmod recovery. Since you can't root stock 1.72 then you won't be able to flash it back again either. Since you have radio s-off all is not lost. You can get root back by flashing back to the older 1.32 ruu and re rooting. When you flash that it will revert your radio back to the older one however.
If you want to update your radio and nothing else you don't have a choice but to get engineering hboot s-off.
Ok, found a tool for ENG S-OFF that I can risk
Radio update then and check improvement in stock ROM before going custom.

So long story short I've done all these to MY incredible several months ago starting at 2.1. I now run latest hboot, radio, s-off, blah blah with CM7. My friend has a stock 2.2 dInc and wants to do the same.
In what order should these be upgraded/installed to go from a stock 2.2 to CM7? I remember when I was upgrading all my files there were certain no-no's that would brick. I'd really like to prevent that.
Right now I'm thinking for his stock 2.2:
Root 2.2
Update HBOOT to .92
Update radio to latest (2.15?)
Perform S-off
Install CM7 rom
Will that work?
When you root it can run the s-off patch for you at the same time. Other than that everything else is fine, no worries.

The newest version of Unrevoked3 installed Hboot .92 and did the S-off for me as well.
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?
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.
