the sumcheck went OK but 6 .was failed to install...Reformating the SD card and trying one more time. Any other idea?
yep, I tried another SD card skipping the optional shopping channel and it worked. 24 wad installed.
if I did not downgrade to 4.1 in the indicated order and sofmod was alredy completed, can I downgrade at a later time?
Yes you can but you should have done it when the guide told you to. There is no reason to be on 4.3 and therefor no reason NOT to downgrade (in my opinion).
If all wads installed properly you can install system menu 4.1 without issues (just make sure you install the correct REGION). System menu 4.1 uses IOS60.
thanks. Is it OK to downgrade after installing the Priiloader and the darkcorp?
should I uninstall Darkcorp before downgrading to 4.1?
yes.. but you need to fallow Ithians guide.
**Edit: Also you backed up your nand right???
