PRS-T1 The most painful thing in the world is that the machine fails and there is no way to

Last month I found a sony prs t1 from the second-hand market. After changing the battery and using the SD card to save the brick, it was able to turn it on, but I found that the original battery was completely dead, so I bought another 3mm thick battery (missing the temperature detection cable.) So I found that it can only discharge, not charge. When I was sad, I found that as long as I pulled out the white cable and pinched it with my finger, the red light for charging would light up and charge it. Although it was hard work, it was interesting, especially since the original battery cost more than $14, which was far more than the price I bought it for.
After that, I found out how to read Chinese from the evening, because the Chinese novels I imported, it shows all ❓. Use calibre to enter the font code in the attached css, and then create a FONT folder in the reader root directory, put the font in nine and you can read it.
However, the good times don't last long, it always displays various wrong pop-ups, so I want root again, so I can install software freely. After using the root package of porkupan, a new desktop appeared in front of me, but it was too slow, so I wanted to go back to the original system. At this time, I swiped the wrong restore-set.zip, so now I am stuck in the boot interface. The opening book is a white progress bar, the power yellow light keeps flashing, and the light of the sd card does not respond. Press and hold home + memu to enter recovery. After about ten seconds, it will keep restarting in a loop. I am very sad.
Finally, I found the jpa method in in-app, bought usb to ttl, welded it, and used putty to link it, but I don't know what to do next. Although I installed ubantu, I don't know how to use these commands. In putty, it keeps restarting in a loop.
Later, I wanted to find a similar ttl method to save bricks, such as kindle, but I found that one of the key commands is bootm + an address, but I don't know if prs t1 can use this method to enter recovery, so it should be able to save bricks.
I looked at the method above the wiki, and there seems to be no effective method. The things on Sony's official website, as well as many links and methods, are a long time ago, and they have long since expired. Or they all refer to each other. If anyone can tell me the method, I would be very grateful.

This is what appears after I connect to putty.

The PRS-T1 is buggy. I got a refund. Later I got a PRS-T2 which is a far better model, though of course the WiFi and Webbrowser is pointless because no valid certs/
