Angry Is this means hardware fault of paperwhite?

Hi, every one. I'm in china , and I had bought a kpw from japan. When I received my kpw, I pressed the power button, the screen change to the "Big tree", and then it stopped!
I bought a USB-TTL convertor, and what it print is as follow. I tried to update bin file, flash main_kernel.img/diags_kernel.img/pw_5.2.0-mmcblk0p2.img, but it still cannot work.
Then I found my print is different with others, Is this means hardware fault? Please help mel, thank you very much.

the print:

Spoiler:



I suppose the module could be failing somehow?
Quote:
Loaded module /lib/modules/eink_fb_waveform.ko (39836 bytes)
but honestly that is outside my knowledge. But it says Loaded rather than an error about the loading itself...

So possibly not that.

But... what confuses me is you say the screen actually "works" so I fail to see how it could be "broken"...

Hmmm... maybe someone with ninja module skills can help you further.


did you try a few things with regards to the module? like err... modprobe to check it actually is loaded. Or modinfo maybe, I dont have a PW so here my help (such as it was) ends.

Hope you get it sorted.



see below... I thought you inferred the screen was working... evidentially not.

Oh dear, it looks like a hardware fault. Before the e-ink drivers are loaded, the PMIC gives an error - for the DISPLAY regulator. That is bad - the PMIC is the power source (or better phrased: the power distribution chip). So likely, the e-ink system does not get any power, hence no wonder that the driver for it fails, too.

If it is open anyway, have a close look if some traces have been shortened. Maybe the cable for the display isn't fit correctly to its socket (is there any?).

So yes, hardware fault, unfortunately.

Given the error messages highlighted in red, I really doubt that this is worth the hassle... If possible at all, since the KPW is a bit more difficult to handle than the KT.
