[Q] Is it possible to downgrade from 3.30 back to stock 3.26?

I have a somewhat unique situation that I haven't been able to peace together after 6 days of searching threads. Any insight would be greatly appreciated!!
My elderly mother bought an EVO recently after I bought one and some idiot talked her into running the 3.30 RUU on an EVO with software 3.26.651.6, baseband 2.15.00.07.28, and hardware ver 3. This also upgraded her HBOOT to ver 2.02. From my thread searching, it seems that 3.30 isn't intended for EVO's with HW ver 3 and may impact the phone's performance and/or battery life. I do believe that there was an OTA for her phone for 3.29.651.5.
I am wondering if it is possible to downgrade her HBOOT and sw back to 3.26.651.6 and the corresponding HBOOT version? I would then want to apply the OTA to update to 3.29.651.5, where she should be. She NEEDS to have a stock phone . From searching threads it appears that I need to root her phone using the 'like a boss" method and then run the RUU 3.26.651.6. However, I am unable to find the stock 3.26 recovery img needed. I do have the stock 3.30 recovery img but am reluctant to use a different recovery img.
Help please, if you can!

A little direction if you can...
Anyone? Just looking for a little direction here. Also, trying to follow the rules and keep this out of the dev section...
Not a noob to rooting, just to the EVO. Rooted my old hero and flashed a few diff roms...just want to make sure I have the right info and am prepared before I start rooting the phone. I really have searched MANY threads and I feel confident about rooting the phone via "Like a boss" and illogos's updates but I didn't find anything about successfully un-rooting to a pre 3.30 software version.
Can I just run the RUU for 3.26xxx after rooting? I'm assuming that will be fine with S-Off and an older hboot.

[Q] [SOLVED] Final question before rooting my DZ

Hi,
I've got my DZ a couple of days ago. It's a secondhand DZ. Previously i've used HTC Touch, Touch Dual, TP2, so this is my first Android experience. I did lots of ROM playing on previous winmo phones, but after reading for these couple of days of Android modding, i learn that flashing another Android ROM is not so simple as winmo ROM.
This is my DZ info:
Android version 2.2.1
Baseband version 12.28e.60.140fU_26.04.02.17_M2
Kernel version 2.6.32.21-g6e170e7
Build number 1.82.707.1 CL317545 release-keys
Software number 1.82.707.1
VISION PVT SHIP S-OFF
HBOOT - 0.85.0009
MICROP - 0425
RADIO - 26.04.02.17_M2
eMMC - boot
Dec 13 2010
I've check with root checker and Titanium Backup, it says NO root access.
I've learned that with 1.82, i will have to downgrade first to 1.34.
In the steps for downgrading, i found that i will have to flash signed PC10IMG. But i also found in the sticky thread there's a warning, not to flash signed PC10IMG if i have S-OFF. So before i can downgrade, i have to get the S-ON.
I've read in a thread :
If for some reason (sending phone for warranty or repair, etc) you want to go back to S-ON:
- If you got S-OFF by flashing an Engineering hBoot, download the official HTC RUU for your phone version and flash the stock firmware back again. S-ON will be restored. This forum contains many threads with official RUUs.
- If you got S-OFF with gfree, it saved a backup copy to your SD card called "part7backup-xxxxxxxxxx.bin". It can be flashed back from a terminal emulator or from an ADB shell:
"dd if=/wherever/your/part7backup-xxxxxxx.bin of=/dev/block/mmcblk0p7
The problem is, i got a secondhand unit without microSD card. How can I get S-ON? I don't know how (what method) my DZ got S-OFF at the first place.
Any help is much appreciated.

You are already S-OFF? I'd find it strange that you'd be S-OFF and not be rooted.

install rom manager and check if there has been a recovery already flashed. Might answer your question
Why do you want s-on? S-off is a good thing

You can check if you got S-OFF or S-ON
by entering bootloader
Power off your phone, then, hold the volume down key and the power key.
You might need to disable fastboot

I've already installed Rom manager and there's no clockwork recvery installed.
I want to flash custom rom. I need a root to do that. To get a root, i need to downgrade. To downgrade, i need to flash signed pc10img. And there's a warning here that said DONT flash pc10img with S-OFF. That's the problem.

I already did that. Bootloader says VISION PVT SHIP S-OFF. So that means i definitely have S-OFF.

I've learned some more from the post here and there. I think i figured out what happen with my DZ. I think the previous owner rooted and S-OFF the phone in the old firmware 1.34 then got an OTA update to 1.84. That update destroyed the root but somehow still S-OFF.
If I follow the direction in this thread, i assume that i can downgrade and root again. I will not need a goldcard to downgrade because currently i have S-OFF.

I am not sure whether it will work. But I am curious too.
I once upgrade via OTA and then I downgrade it following the instruction as per your link reference too. I rooted succesfully.
But, my DZ was S-ON.
Now you are in a different situation. You want to downgrade and root it but you already S-OFF.
Do you want to try it?
Cheers

I guess i have to try it.. will report after trying. Thnks all for the help..

Your theory on the previous owner having used the over the air update after rooting seems right to me. I've read more than a few times it will still show S-OFF but not be true S-OFF. Because you can't get S-OFF without root (well surely not on the newer 1.82's)

I'm not familiar with the 1.82 issues (why normal root methods fail on 1.82) but I wonder if temp root works, if you have radio S-OFF and temp root works it might be as simple as:
1. Obtain Temp Root (even Visionary could work)
2. Flash CWM Recovery (I'd use the flash_image method and not ROM Manager)
3. Reboot into CWM recovery
4. ...
5. Profit (Install a new pre-rooted ROM)
Of course this all depends on if temp root works with 1.82 and if your S-OFF is really S-OFF but it seems like a quick & easy thing to try.

I did it guys. It went smooth. Still needs goldcard though due to unmatched CID.
I'm on 1.34, rooted and S-OFF. Next find out ROM that i like most. Any recommendation? it has to be cool and fast..
So i figured that the warning "do not flash signed PC10IMG if you have S-OFF" is before we have the misc_version method. With misc_version "main is older" problem will never occur, provided misc_version done correctly.
Thank you all guys for your help and time especially for those guides starter. You guys are the ones who make this forum SO GREAT!

Congrats .
The first time I did after rooting was install ROM MANAGER premium version.
There a lot of rom to try with the easiest way..
Good luck

Issue upgrading a rooted evo from 2.2 to 2.3

Ok let start by getting a few things out of the way.
1 I'm sorta a Noob ok kick me crack a joke or two I don't care as long as you help
2. I have Htc evo of course running stock 2.2 (baseband ver 2.15.00.11.19)
Kernel ver 2.6.32.17-gee557fd htc-kernel and18-2 #15) (S-ON)
Radio-2.15.00.11.19 and I'm using a Mac (if that help)
3. I rooted it using the unrevoked method.
The device works fine but bit I'm having a big issue trying to upgrade from 2.2 to 2.3.
I have been trying to unroot the phone so that I can update OTA.
But no matter how many times I try to unroot it my super user is still there
I would rather flash the phone to a 2.3 GB rom thats 2.3 with sense 2.1 or 3.0.
I've tried this the method found on youtube using the s-on and dropping the image file (zip) on the sd card and flashing it
by making sure you install the (s-on) patch
and re-flashing the RUU (PC36IMG).
but when I did that it said that i was re-flashing a old version.. so I found a newer version.
But when I drop it on my SD card as (PC36IMG.zip) it reads it, checks it then... takes me right back to the Hbot screen like nothing never happen!!!
I've been working on this for 3 days I've even tried restoring and everything.
I've been searching online for answers but I can't find anything that helps either its not up to date or just flat out dont work.
at the end of the day i just want a damn evo running BG 2.3 sense 2.1 or 3.0 would be nice.
​
oh by the way when i try to run the OTA it reboots startes to load get about 35% then goes to the exclamation mark / triangle.
I'm out of options please help me out! I've searched and read on for about 3 days now.
please either help flash the device to a stable working 2.3 with sense 2.1-3 or un root it so i can update it ota and re root it again...

Wow man, between the general and q&a sections there are seven threads dealing with this very topic. Yet you couldn't find any of them?
If you want to unroot and take the ota you will need to flash the s-on update and run the 3.70 ruu to unroot. Once you do that you'll be completely unrooted and like new. Then just take the update and it should go through without any issues. If, however, your bootloader shows a firmware version higher than 3.70 and you are s-on then I'm sorry to say you are stuck like that.

I've dont that and i still can not remove the root

You'll need to flash the PC36IMG through fastboot to see what's going wrong with it then. To do that download the AutoRoot tools zip and the PC36IMG_3.70.651.1.zip from the link below. Once you have them both unzip the tools folder and place the PC36IMG in it, then run the FlashZip script and tell it to flash the 3.70.651.1 zip
It should flash ok but if not it'll give you an error message saying what went wrong with it. Keep in mind you're going to be completely unrooted if your bootloader shows S-ON.

What HBoot do you have... I think just flashing one of the stock GB roms probably would of been easier just my opinion....
Sent from my EVO rocking Evervolv Gingerbread

i just found a ruu for 3.70.651.1 ... installing so far so good

You do realize that you'll lose root until a new method is found, correct? If you want to stay rooted, you need to reroot, then flash the stock rooted 2.3 rom.
If you want a newer version of Sense, you'll be outta luck there too - the new update is same ol' Sense 1.0.
Just making sure you realize this, since so many people are whining about not being able to root the OTA and being stuck with the uneventful update.

[Q] Unroot procedure and RUU that can be rooted again

Hi,
I have HTC Desire GSM, rooted, s-off. Because of some issues with the proximity sensor i want to unroot the phone and send it back to HTC for maintenance. Before continue i must say that i have tried to clean the sensor, tried to remove the screen protector but the problem remains
However, i downloaded the hboot downgrade from alpharev site and updated the phone. Now the hboot version is still 6.93.9999 - will it be replaced when i flash the RUU?
Before flash the RUU i want to be sure that i can root the phone again once i get it back from HTC. I used the unrevoked to root my phone but as i see it's for hboot 0.93 and lower. What version of RUU should i use? I prefer to be froyo.
Thanks.

Yes, the bootloader will become S-ON once you use the RUU.
The best option is to use the corresponding RUU to your network provider e.g. my device is branded Vodafone, therefore if I were to send back for warranty purposes I would use the latest Vodafone RUU.
All RUU's are available on www.shipped-roms.com
If you are unable to find the correct RUU for your phone, or are unsure of which one is right for you, simply use the 2.3.3 Gingebread RUU available from htcdev.com (there is also a link available on my guide from #Resources)
Lastly, you can root and S-OFF your phone as many times as you please (Being it is not rooted or S-OFF already)

Thanks for the reply. I have found tha RUU i need
I have read that GB RUU cannot be rooted and i should downgrade to 2.1. So i will use Froyo instead. Thanks a lot

When you get the phone back you're probably more than likely to get it back with 2.2 anyway, also you have read wrong, in addition to the fact that unrevoked is now pretty much obsolete and it is much easier to S-OFF and flash recovery rather than root the stock system.

There are so many threads and it's easy to get confused
I suppose you are talking about 4ext recovery?
What's the way to s-off the phone? Is it still whit alpharev?
I will search a little bit more thank you very much

Wow you really need to do a lot of reading.. you can flash any recovery you want, whatever suits your needs...
Use revolutionary instead, it's a lot quicker and easier.

What android version and radio is the phone on? If its 2.3.4 do this http://forum.xda-developers.com/showthread.php?t=1306400. If any other lower version just use unrevoked http://unrevoked.com/#inc.

android version is 2.3.4 - 4.08.605.2
radio version is 2.15.10.07.07

Hi I am stuck in step downgrade, while attempting to install the zip tells me that the version is old and can not continue the process

I apologize for not copying and pasting into this thread for easier access but it is kind of a pain in the butt because links do not transfer over anyway, this is a guide that I have written for your exact situation. 2.3.4 downgrade and s-off. You will notice that the order of things may not be what you expected and that it is a little more labor intensive than you expected but I have used this exact process with two phones and it came out quite well. Other guides actually have this information already but I found them to be cluttered and hard to follow to I wrote this up to make this as easy as possible for users to root their phone and flash their favorite ROM. Good Luck!
