How do I load firmware on a Libra(1)?
Hi, to keep it short

-deep end discharged my Kobo Libra after a trip
-voltmeter showed a dead battery
-replaced it with a new one (soldering) (can be charged via USB)
-device can't be hard reseted
-still shows my last ebook cover and is found via USB under WIN10 as "se blank 6sll"

by checking your forum I found out that it's bricked, is there the possibility to load the firmware back to the device via USB +script/software?

got this one (MARK 7 from your table): kobo-update-4.30.18838

it was just dead when I wanted to read something again. Frozen with my last ebook as a cover. I charged it 1h with no diffrence. Then I opened the back and meassured with the voltmeter the battery potential of 0V. So I decided to replace it. I soldered off the old battery, soldered on the new one in the previous cable orientation/polarity.
I checked the voltages with the voltmeter before and after charging it via USB.
The meassured battery potential rose from 3,5V to 4,2V - capped. Since then it's bricked. I started to factory reset it a described by kobo. But it shows no reaction besides being "se blank 6sll" under windows

Judging by the picture, a not thick 3000+ mAh battery will fit there.

You cannot load firmware on a Libra 1 as there is no such device called Libra 1. It's a figment of your imagination.

Enough, Jon. Your snarkiness when people do not use a device name that you consider acceptable is getting extremely annoying.

The alternative though I find it very hard to believe is that you imagine that your behaviour is actually being helpful.

I'm not the first one to bring up the issue of Libra 1 being wrong.

When there was only one, it was a Libra, Kobo Libra or Kobo H2O Libra.

Now that there is a Mk2 Libra, it's reasonable to call it the Original Libra or retcon it to Libra 1. Libra is now ambiguous.

The official Amazon names are pretty useless.

The Aura H2O has 3 different editions. The Libra H2O has no other editions. The Libra 2 is not an edition 2 to the Libra H2O.

That's like saying that the Aura H2O is the 2nd edition of the Aura HD.

Anyway, that's all I'll say on the matter.

No it isn't. It has a name. Use the name that is printed on it, shown in the menus, is used through out the Kobo's support site. If you tell someone to search for "Libra 1", you won't find anything useful.

And it is weird seeing you say this. You jump on people for being inaccurate in so many ways. But here you are encouraging people to be inaccurate.
