Good luck! Keep us informed please. We at 4pda have got many reports on successful restore with official 5.8.11, but no one has tried 5.8.9.0.1.

Does anyone know reason for "UPDATE ERROR: 4" ?
I succeeded in copying the 5.8.9.0.1 firmware, but got the error.

Is it related to file integrity? I'm not sure if I copied it completely. Or downgrade is not allowed for the firmware/uboot?

Most likely the corrupted fie. Do you have enough time to check md5 of the copied file?

@hius07 failed on the first trial, and gonna try some more later on.
I think 20 seconds is not enough for a integrity check.

What? Rare situation happened!

During a copy, the Kindle showed up as a drive persistently, which means there's no more 20 seconds limit. But it seemed to be related to battery status. My Kindle showed a battery low alert and something related to computer.

Photo attachments are below.

----------------EDIT:

After unplugging the USB, I found that the Kindle is actually INTO the system, I got full GUI. The "battery alert" mentioned indicated that Kindle dectected USB connection and it's charging. But the screen didn't appear to be in a normal scale.
It's really rare and hard to enter. After copying evrything I need, I tried to install 5.8.9.0.1 update (full md5 integrity checked), and it appeared "UPDATE ERROR: 10", which is a new error code I've never encountered. I've checked the firmware version and it's 5.7.4.

But luckily, I've got all the firmwares copied in advance in case 5.8.9.0.1 doesn't work. Now it's again in the bootloop.

Now I got two options:
  1. Restore with fw 5.8.10/5.8.11 which I already fully copied.
  2. Try to enter the state again, which may take a long long time.


Any suggestions? Thanks everyone!

PS: @hius07 Have you ever seen these ill-displayed system in any other cases in 4PDA? It's working fine but everything seems to be smaller.

Lucky. Time to fix your device.
If you could say exactly how you achieved this state it will probably help a lot of people.

@bozza111 Actually there's no any sort of "ways" to do that. Just happened by chance. I was copying files between bootloops and then it happened. I noticed the copying time for one time is already over a minute and after that, I unplugged and the system GUI showed up.

If there has to be a way, I think it should be trying more with Kindle connected to PC. And maybe the possibility is greater when you are doing a Kindle disk I/O.

Update:
Now updated to 5.8.10. Kindle runs normally, but of course, without jailbreaking .
Trying again to downgrade to 5.8.9.0.1. Hope it works.

PS: Even though the firmware is updated to 5.8.10, the system still looks a bit ill-displayed occasionally as you can see from the bottom of the display, there's a grey area.

Did you not try to install the jailbreak before updating?

Just forgot to install the jailbreak, stupid again .
Good news is Kindle is back to life. Bad news is not able to install any copied bin files. They got deleted by Kindle once I disconnect it from the PC.

Anyway to solve this?

That's all, you are on 5.8.10 without software jb possibility.

It seems that after huge amount of reboots the system (initial factory 5.7.4) has finally restored itself. Very interesting.

All right. Thanks anyway.

And anyone who wants to know about my experience can post under the thread or just PM me. I'll be happy to share.
