But the most stupid thing I have done is trying to downgrade it to 5.7.4, and of course it failed  (I should have installed 5.8.9.0.1 fw!!).
And now my Kindle is experiencing bootloops (Kindle start -> progress bar -> couple of more restarts -> "Your Kindle needs repair).
But there's still hope as my PC is able to recognize the Kindle as a removable storage for a period of short time (about 20 seconds), and then disappear. I've read some threads on the forum and found that the only possible way is to split an official firmware into file pieces and copy them one by one to the Kindle when it's recognizable, and then combine them into a full firmware.bin file. The method comes from 4PDA, but no links are provided so I could just try my best.
It's easy to split into parts and copy them to Kindle, which I already succeeded. But just can't get them combined as the I/O speed is too slow and time is limited.
Also tried split file and cat them into one file, but still not that possible.
Anyone had the same experience? Asking for help now. 
Thanks in advance!  |
I'm sorry this happened!
That thread you linked also discusses fixing it by splitting the official update into smaller chunks, and installing with that, but it also doesn't explain how to do it.
If I had to guess, it looks like maybe kindle introduced some new hardware combination that is not supported by 5.7.4, but may also not be supported by 5.8.9.0.1, the results are being so mixed.
If it is already broken, I might be able to prepare a package that could work, but I can't make any promises. People have said DO NOT use the DO_FACTORY_RESTORE file.
What I think I can do it take one of the official updates, and remove the voice files, which will make it much smaller. That may be able to copy on in one go, durign that ~20 seconds.
If you do that, you will probably lose your chance to jailbreak, but it will be working again.
I can also try to take 5.8.9.0.1 and remove the voice files, for the same effect, but I can't make any promises that will work either, or make it worse.
