I am hoping some one can help. I have a similar problem with my Koboreader. The upgrade failed. I cannot get any books on the reader after the upgrade. I followed the instructions in this thread. I finally got it into the upgrade mode, installed the new reader software on the PC. Then I connect. At step 6 it disconnects and tells me to phone a number. I see that SameerH helped another person with the same problem and he got his working. Hopefully someone can get SameerH to contact me at
markdgal@yahoo.com with the ame answer. Thank you
