Hi All,
I'm reading this thread (and also others for kindle DXG register problem). I face the problem after I factory reset my Kindle DXG device. Initially I had issues connecting to 3G and factory reset didn't fix it. I solved the issue by manually selecting 3G network from 311 page, but then I face current problem with "Missing certificate" and "Unable to register". I tried all updates and etc. but without luck (as everyone here). I've spoken to Amazon support, but they couldn't do more than re-registering my kindle to my amazon account, but the device was still showing "not registered". I was able to download all my content and upload it locally to my Kindle and read it, so it was not such a burden to have not-registered device.
I wanted to share with others what I was able to achieve, without registering my device and now I'm able to use all functionalities, that I've used before, when the device was registered.
- The first thing I use, was my kindle store to download books, that I bought, but I've workaround it via downloading to PC.
- The second thing than annoy me is the Collections thing, as I'm using them quite often (very useful when you have more than 10 books, that can't fit single screen). But when your device is not registered, you can't create/manage collections. So here is how I solved my problem:
- As I read Cyrillic books, I have jailbreak and unicode hacks installed from here (https://www.mobileread.com/forums/showpost.php?p=973688), files Update_jailbreak_0.13.N_dxg_install.bin and update_unicode_3.1_k3g_255_fonts_install.bin, with linkfonts folder.
- I've added Update_usbnetwork_0.57.N_dxg_install.bin in order to access Kindle root FS and make kindle think that it's registered. There are threads in the forum about usbnetwork installation ( I didn't keep reference of them). I'm a Linux user and It was quite straight forward hack. I've attached the simple steps I've done.
After I trick the device to think that it's registered, I was able to use all disabled functionalities, except those requiring internet access (e.g webBrowser and shopping from kindle store), but I can use them from my phone/PC. So till Amazon fix the issue (I thought there won't be any fix, but this thread keep the hope alive), I think this fake registration is good workaround.
