Can't revert SUPEE-9767 v1

Question

I want to upgrade my Magento version 1.9.3.3 to 1.9.3.4. As I understand it I have to revert SUPEE-9767 v1 using the command sh PATCH-SUPEE-9767.sh -R.

When I run this command I get the following error log from it:

sh PATCH_SUPEE-9767_CE_1.9.3.2_v1-2017-05-25-09-03-28.sh -R
PATCH_SUPEE-9767_CE_1.9.3.2_v1-2017-05-25-09-03-28.sh: 14: PATCH_SUPEE-9767_CE_1.9.3.2_v1-2017-05-25-09-03-28.sh: 127: not found

So unfortunately I'm not able to revert this, so I can't upgrade to 1.9.3.4. Does anyone have a clue about what is going on?

Answer 1

You are get Unreversed patch detected! errors because original v1 patch did not install successfully. In other words, whenever you see a message "Unreversed patch detected!", V1 patch didn't not make any changes to those files when you installed it originally. It skipped them probably.

For you to be able to reverse V1, you have to open the V1 patch with an EDITOR and remove patches code for the files that you see show "Unreversed patch detected!" I counted the following from the list provided:

app/code/core/Mage/Adminhtml/Block/Checkout/Formkey.php
app/code/core/Mage/Adminhtml/Block/Notification/Symlink.php
app/code/core/Mage/XmlConnect/controllers/Adminhtml/MobileController.php
app/design/adminhtml/default/default/template/notification/formkey.phtml
app/design/adminhtml/default/default/template/notification/symlink.phtml
app/locale/en_US/Mage_Adminhtml.csv
app/locale/en_US/Mage_Core.csv
app/locale/en_US/Mage_Dataflow.csv
app/locale/en_US/Mage_XmlConnect.csv

You also have HUNK failed at 232

app/code/core/Mage/Checkout/etc/system.xml
Hunk #1 FAILED at 232.

You could possibly modified this file manually after V1 installation, compare this file with original Magento system.xml file for your version. There must be something missing in the code.
