Unable to revert Security Patch SUPEE-10570 v1

[jensusu]

I do not understand why this patch won't revert. I'm using CE 1.9.2.4 and trying to revert SUPEE-10570v1 to apply SUPEE-10570v2, but I'm unable to revert and receiving this code (I have checked all prior patches and they are the correct versions):

app/Mage.php

Hello @jensusu

Do you have v1 or v2 of Patch 9656, if you have v1, revert and install v2 of supee-9767. Then try installing SUPEE-10570v2. Try git diff the files with a clean repo of your magento version. Run the patch with sh (nameofpatch).sh or ./(nameofpatch).sh

@Manish Mittal There is no patch with the number 9656. If you mean SUPEE-9652, there is only one version which I checked in my applied patches file:

-e 2017-02-07 21:13:34 UTC | SUPEE-9652 | EE_1.14.3.1 | v1 | 4038f0785d828794083f53f10c01aaa6af403523 | Tue Jan 24 15:03:12 2017 +0200 | 9586981e6ca8b255014b242d50b68b88525b0754..4038f0785d828794083f53f10c01aaa6af403523
patching file lib/Zend/Mail/Transport/Sendmail.php

I also have supee-9767v2 already installed. I have 10570v1 and trying to revert it so I can apply 10570v2, but it won't revert and having this issue. I also have a development site with the exact same theme and patches and I could revert with no issues. Also, which files am I supposed to do a clean repo of Mage_Catalog, Mage_ImportExport or Sendmail?

app/locale/en_US/Mage_Catalog.csv
-OR-
app/locale/en_US/Mage_ImportExport.csv
-OR-
lib/Zend/Mail/Transport/Sendmail.php

@Manish MittalSolved with clean version install of app/locale/en_US/Mage_Catalog.csv from ver 1.9.3.8.
