Hello,
i bought a W810 and flashed the unbranded firmware onto it.
Then I tried several patches and I have to say that I am really impressed about the possibilities of this (old) phone.
Also the battery power is very very good compared to newer phones..

Ok now to my question:
I installed the patches with setool lite.
After all I wanted to remove some patches (bookmanager) so I just pressed "yes" instead of "no" in setool lite.
The patch seems to be removed, but my question is how does setool knows which blocks where there before installing the patch!? Or is every patch a complete new line of code which will be added to my phone..
I just ask because I don't want to have "dead" code in my phone..

Thanks and regards from Germany!

no, it replaces values in your main firmware with new ones and when you remove patches, it removes the new values and the old ones and restored. you understand or you want a more detailed explanation?

Here's a quick explanation of the contents of a patch

Take this patch for W580 R8BE001 for example:





Everything that starts with a ';' means its a comment and will not be read by the patching software.
It usually tells you info about the patch. The phone and version its made for, followed by the description, followed by the person who made it, followed by the person who ported it to that phone.



Is the main part of the patch.



Is the address where the value needs to be changed



Is the original value of this address (So that it can be removed in the future, and also to check if it matches)



Is the value to replace that original value in that address.

Thus, if you were to remove a patch, it'll "swap" the last two parts of each line, making it patch back in the original values. Get it?

Got it thanks for that good post!

No problem!

great i was in a hurry because i was busy that's why i didn't do it detailed but great explanation.
