What does this mean exactly?

[nguyendqh]

Hello Phateless do you remember me? lol I am always on diff name so ya.

But yes PD15IMG.zip is not the golden solution to everything. It all depends on how you originally rooted your MT4G as VISIONary+ (TempROOT) and root.sh (PermROOT). In that case your S=OFF security off flag is dependent on the eng hboot which was pushed to /dev/block/mmcblk0p18 during PermROOT.

Now since its not true security off once you have newer radio. You try to run PD15IMG.zip (Sense 2.2.1 Rom/Radio 26.03.02.26_M) after the first update which is stock hboot you would be locked due to it changing S=ON thus on next step it will fail due to the image being older than originally on which is currently flashed which would be the radio. In this case your in a point where you shouldn't be as you can be locked out and no way to reroot. which I am working on finding. This also goes for gfree radio s=off.

If you do want to go back download PD15IMG.zip (stock radio 26.03.02.26_M) and then flash it once that is done then you can revert back to stock rom/radio using standard PD15IMG.zip (Sense 2.2.1 Rom/Radio 26.03.02.26_M). Keep in mind unless the new PD15IMG.zip is out you can't revert it back if your locked out due to source being outdated than current image.

Found this post here in THE Bible. Trying to understand exactly what it means.
What is he saying here?
Can someone put this into noob terms please?

I am not sure how to explain it furthermore as when I posted that it was clear to everyone, but ill try to simplify.

The original stock rom that came with our device was 2.2.1S and later we had GB2.3.X port and we mostly switched. Then came the radio rom which I hope I don't need to explain what the image does. So the standard stock radio that came with our device was 26.03.02.26_M. So later on as Panache came out we had leak to other radios which user could flash, thus changing it from stock radio to leaked radio. I hope it make sense up to there.

Now keep in mind we have 2 type of root meth as one is via TempROOT/PermROOT as I explained before via VISIONary+ which just push the eng_hboot and gives the illusion of S=OFF but the true security is not off as that is only done if you do the other rooting meth which is PermaROOT which disables the radio security completely.

Now the problem few users faced was when they flashed the leaked radio and they wanted to revert back to stock rom/radio via PD15IMG.zip for our MT4G (IDD15000). The installation would fail only for folks who had root via PermROOT as they never had true S=OFF thus once the eng_hboot is replaced with stock bootloader the security is disabled thus user can't complete the second part of the process which would be flashing the radio. So only solution was that they first revert back to stock radio or wait for newer radio because the source of the image inside PD15IMG.zip was older than the radio.img that was already flashed inside user's MT4G.

I hope it explains if not well IDK how to explain any better man :O

So if I'm understanding this all correctly, how I find out if this will affect me?
Where and what information should I provide you in order to find out if this will happen to me as well.
I'm getting ready to send my phone in for an exchange and was looking to flash PD15IMG.zip before doing this when I came across this post.
I rooted my phone with Visionary R14 and Terminal Emulator.

What other info do you need? Please let me know. Thank you.

At this point it wont affect you as thats obsolete due to TMoUS releasing newer stock rom/radio for our MT4G few months ago as Panache radio leak is older than the current stock rom/radio. As its GB2.3.4S which comes with the newest radio which is newer than any radio you flash. So the source of the PD15IMG.zip if you have the newest one then it will always be newer or equal to the radio.img already in device and it means in simple term it will flash the 2nd part. I hope it make sense as it should not affect anyone now. Even if it does all they have to do is run the current new PD15IMG.zip and it will fix the issue which user faced few months back.

If this is all about going back for an exchange, i recently did just this. Please see my post on the topic: http://forum.xda-developers.com/showthread.php?t=1241740

If all you did was the temproot/permaroot method via visionary+, and not the gfree method (gfree is actual s=off), then I believe some of the steps may be different. Specifically, you may be able to skip the whole bit about turning s=on again.

So which is it?

 

[nguyendqh]

So rooted via Visionary R14 and being on Virtuous Unity (newest update)
I should be able to flash PD15IMG.zip from this link here: http://forum.xda-developers.com/showthread.php?t=863899
and have no problems yeah?

Sorry for all the questions. But yeah I'm only half to 75% following what you're saying.
I'm not advanced yet. =(

Thanks for the help again though.

Keep in mind PD15IMG.zip is the default system file for our device which is checked on the bootloader as our device ID is PD15000 thus getting the PD15IMG name. So PD15IMG.zip can be multi files as we have 2 of them 1 is 2.2.1 and newest one is 2.3.4 just look in the dev section you will find the newest PD15IMG.

I did not use the gfree method.
