Default [Q] how to install OTA without losing data

OTA telcel
hi all I share the link to the OTA telcel reaching all this right now

h t t p : / / w w w .mediafire.com/download/2wtup1s49uctgt8/Blur_Version.14.81.1.falcon_umts.AmericaMovil.en.M X.zip

the problem is that we have root and unlocked bootloader get an error

I already try:
1 - Restoration Projects the stock recovery and unroot from SuperSU goes wrong
2 - apply by sideload from stock recovery and also get error
3 - apply by brand sideload from CWM and it is for this is XT1030 falcon_umts and modify the line that I found only in the build.prop and the same error keeps coming.
4-apply the zip from CWM like any other zip goes the same with sideload.

I'm looking for how to install the OTA without reflash the firmware if you do not maintain all data

if someone wants to test and share results, all the tests I've done I have not been but I have not caused a brick or data loss.
