What do i need to do to prepare my device to remove this rom and get back to stock? unfroze knox and now what..

First you need to upgrade to MI1, then you can go to 4.3 and retain root. Head over to XDA. We already have a big thread on how to do it. Basically you need to ODIN back to stock MI1 and root with De La Vega and change a param.sh file and use survival mode in SuperSU, then upgrade to 4.3 and retain root. 

 

Here is a link to the thread on XDA.

Start at post 1.

 

I CANNOT STRESS ENOUGH TO FOLLOW THE POST TO A T!!! THERE CURRENTLY IS NO ROOT METHOD ON 4.3 IF YOU MESS UP. THIS IS GETTING YOU ROOT WHILE ON 4.2.2 MI1, THEN RETAINING THAT ROOT TO MOVE TO 4.3.

thanks for reply, I will study before i jump in and plan to report back...

EDIT

got MI1 just fine but am stuck trying to open FILENAME: rootdelavegajfltevzw.7z

can you provide a link to a mirror with a.zip file or instruct how to open..........

[portscan]

If that's a zip file you need to extract the tar file from the zip and run the tar file in the pda section of ODIN.

[portscan]

If that file is corrupted use this link to get a good file. It will be a zip and the tar is in the zip. Just extract and run in ODIN

I have been able to obtain root privileges but I cannot keep them. something keeps breaking root

[portscan]

What's it saying? Did you leave survival mode on in SuperSU?

[Hollywood67]

No, I have not gotten that far yet Here is where I have made it too:

Step 1 - Preparation
 

Quote:

First we need to prepare your device by returning it to a factory stock image to make sure all mods and system-related changes are removed (or OTA will fail)

• Head over to this thread and download the VRUDMI1 Factory Image and flash via ODIN
• Let your device boot back to OS and confirm everything is working as it should
• Head over to this thread and root your device exactly as per instructions there
• Let your device boot back to OS and confirm everything is working as it should and you have root access as well
• Do Not apply any other mods or anything else until all steps in this guide are complete or OTA will fail!

Step 2 - Restoring One Modded File Back to Stock
 

Quote:

Next we need to restore one modded file that was necessary for the root method from the previous step back to stock in order to allow the OTA to complete successfully

• Download the prepare_param.zip attachment I have in this post to your computer/device and unzip the prepare_param.sh file inside it
• Move the prepare_param.sh file to your device SD card (internal or external doesn't matter)
• Using app like Root Explorer, move the prepare_param.sh file from your SD card location to replace the one located already in /system/bin/
• It should ask you if you want to replace the file (if it doesn't ask you are moving to the wrong location)
• Once it is moved, set the permissions on that file to rwxr-xr-x (Important!)

Went to play store to purchase pro version of superuserSU and lost root. what am i doing wrong??

[portscan]

Don't use the stock image. You have to use the Root De La Vega image.

[portscan]

I am going to assume you will have to take the route I did. Some have been able to get the stock image to take root while others couldn't. Looks like you are not going to be able to. You will need to use the Root De La Vega image like I did. This also means you won't be able to take the OTA. You will need to flash the 4.3 update zip in stock recovery. I have the 4.3 update zip to flash in stock recovery as well.

[Hollywood67]

i have been using the image from de la vega. i think i understand you to mean the ota will not work for me and i will need to manually flash 4.3 in recovery, but it seems i am not there yet. Don't I need to be rooted first? I have gone through the de la vega root method three times now, maybe i will try again

[portscan]

Yes, you need to be rooted. Are you rebooting the phone and removing the files and all like it says? That step is very important.

[portscan]

Once the de la vega image is flashed you put the root files folder and the other file on the root of the internal storage with the ext sd card removed, reboot, wait for boot, then remove the files and reboot again. You're doing all that, right?

[Hollywood67]

Yes. I think I have been following all instructions properly. It will root, but something breaks it. Trying to figure out what that is??

Hrmm. Never had that happen.

[Hollywood67]

Had one mod leftover that I just deleted. Will try again later.

The flash should wipe any mod you had.. Anything frozen with Tit?

[Hollywood67]

Yea thats what I thought too. Ran a batch "defrost" on titu before starting las night

During step three in the OP, when opening up superuserSU my phone breaks root. Can you help?

[portscan]

I can't see a reason why it would be doing that.
