Hi
Way to go?
I have been a year a quite happy user of Koreder. However after an install of KPVBooklet which I found unstable, I uninstalled it. It had left a lot of documents on the Kindle side that I could not erase, even if the documents were gone... Now my mistake: I thought I could only deregister and register again my Kindle to Amazon to make these empty documents disappear. Not only they stayed but Amazon politely informed me that my PW3 wifi G090 G1 version 5.7.2.1. was no longer a test machine and that I had to inform "Developer". (see screenshot which I do not translate). The effect of such a warning is that, for example, I cannot launch KUAL and instead a dialogue box pops up telling me to read this letter...
What I did after that
I upgraded -downgraded successfully to
5.7.4. initial bin after downloading it (735 MB) but the Amazon warning is still in place.
Question
I am looking for advice: should I reinitialize totally the PW3 and downgrade again to
version 5.7.4. initial?
Should I try directly some jailbreak even with this Amazon warning?
Thanks for your help and advice.
EDIT: now on my way to a successful new jailbreak, after a full reset, 5.7.4 and so on.
I did not read any previous warning about NOT REGISTER. It makes you lose some hours...
