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:
- Restore with fw 5.8.10/5.8.11 which I already fully copied.
- 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.
