How to unroot from Calkulins patched rom?
 

So I've updated to Calkulins patched latest ROM and still rooted. I also updated to his Wimax IMG. But now I need unroot so I can return the phone before my 30 days is up. I can no longer use recovery to flash back to a previous NAND. Is there any other way to unroot. Maybe reinstall the complete latest RUU..exe? Does anyone have the exe file so I can try. I've only been able to find the zip files but I can't run this because I can no longer run EVO-recovery. Will Sprint even care?...well technically I have to return it to Radio Shack.

try downloading the current version of htc sync and the stock shipped Ruu then update it via the ota after reflashing

Re: How to unroot from Calkulins patched rom?
 

Thats not gonna work.. I downloaded his patch too and the only way youre going to downgrade is by doing toasts part 2 of his recovery method and following all of the instructions. ONLY then will you be able to flash the pc36img otherwise itll keep telling you that youre trying to flash an older version and fail. After that youll be able to run the ruu. Without doing that first, the ruu will get about halfway and fail everytime. TRUST ME...took me a whole day to figure out how to do it.

Edit: And this is assuming that you still have root access.

At xda there is a step-by-step thread on how to unroot. I unrooted and returned my phone to its original state. Don't remember the exact thread but if you go to that site and search unroot ego you should find it.

Re: How to unroot from Calkulins patched rom?
 

Its not necessarily the unroot thats the problem though.. its the fact that the patch included the ota update and upgraded the bootrom. And it wont let you overwrite it without going through those steps first. If you dont know adb I suggest you learn it.

i never had a issue with my way. I guess I know what I am doing

We poated a tutorial at cra-developers ill post a link in a hit.it works a 100%

Re: How to unroot from Calkulins patched rom?
 

Then you obviously didnt flash calkulins rom/patch that we're talking about here. The ruu WILL NOT flash over it without downgrading the bootrom first its not possible. There are a ton of people on xda that had to go through the same steps just to be able to flash the ruu because it wouldnt work. As a matter of fact just flashing the ruu wont work because once the update tool boots its going to stall because it wont be able to even find the usb unless the phone is put in hboot. And even then it still is going to give the "cant update due to this being an older version" error.

By the way this is what I had to do... and 10 times out of 10 you will too if you want to get back to stock.

U don't need adb with terminal emulator ur good

Re: How to unroot from Calkulins patched rom?
 

true... but its a ton easier as compared to entering all those commands on the on screen keyboard lol. especially if you use swype :laughing6:

Re: How to unroot from Calkulins patched rom?
 

Is there any need to unroot to return your phone? Just return it and walk away.

Re: How to unroot from Calkulins patched rom?
 

To tell u the truth it depends Sprint store or bb?bestbuy don't really care but spriny does they ll say u voided the warranty by tampering with the OS

Re: How to unroot from Calkulins patched rom?
 

imo I think terminal emulator is better no pc no wires no setting up adb downloading drivers

Re: How to unroot from Calkulins patched rom?
 

Okay, say you took it to the store and they say you are out of warranty. If you take the phone back, unroot it and revert back to stock what do you think happens then? Just hypothetical.

Re: How to unroot from Calkulins patched rom?
 

My problem also is after I patched with Calculins Wimax IMG I can no longer load the older IMG. It just keeps giving me a failed error. I think if I can get that IMG to load I can run EVO recovery and then load a saved nand and then flash it to the previous stock rom to unroot.

Edit: actually if can get recovery to work I can just flash it to the stock update zip that Calkulin posted.

Another way maybe is flash it with the current sprint ROM. But I can't find the exe to run on my PC. There's a big change the phone will deny it though since it already has the same version.

Re: How to unroot from Calkulins patched rom?
 

That's a good point. I bought it from Radio Shack so maybe they won't care. But either way I still would like to put it back to stock just incase.

They will flag ur device (esn #) on their system .so no Sprint store will exchange

Re: How to unroot from Calkulins patched rom?
 

follow the steps i posted

Re: How to unroot from Calkulins patched rom?
 

Okay, good to know.

Re: How to unroot from Calkulins patched rom?
 

Jocampo thanks for the link. By chance do you have the PC36IMG.zip on that link. Seems to be broken. And from what I read it is not the same as the first one.

EDIT: Nevermind my dumba$$ didn't see the mirror link. That's the only thing I'm missing. K..brb

Re: How to unroot from Calkulins patched rom?
 

Thank you! this the method I'm doing also but using adb shell. Hope this works.

Re: How to unroot from Calkulins patched rom?
 

Jocampo and brownhornet thank you so much for your help!! That method brought my ROM down to or at least made it think I had 1.17.651.1 and then just ran the RUU and was back to stock 1.32.651.1. Thank you thank you thank you!!

Re: How to unroot from Calkulins patched rom?
 

I'm such a noob on this, How do you use ADB command? Some one care to explain step by step.........like where to download and how do I open shell?

If you know dos command its pretty much the same principle. Below is the link for the android SDK for windows that I used. Unzip it into either your c drive or desktop. You need to shorten the folder and subfolder names to 8 characters or less so its easier to get to in msdos. When you open up a dos prompt, change your directory to the tools folder. then just type "adb shell". If you need super user permission just type "su". I just learned about adb today so if you need more info you should be able to google it.
