Note: Rooting Sony DPT-RP1 & Impressions

I’m noting down the references I used to root Sony DPT-RP1, plus a tiny bit of hands-on experience.

  This is the tool used for rooting.
• GitHub - HappyZ/dpt-tools: Wiki - The-Ultimate-Rooting-Guide
  The “official” guide written by a pro. Very detailed.

  If English is a bit hard to read, this Chinese tutorial is a good reference.

There isn’t much to say about the rooting process itself. Just follow the official guide.
The only issue I hit was adb devices showing no permissions; see [http://developer.android.com/tools/device.html].
The fix was adb kill-server && sudo adb start-server. Running adb with sudo made it work… pretty ridiculous.

Good thing I had some basics from tinkering with Enable China Telecom SIM Support on Pixel 3 before, otherwise this might’ve been a bit rough at the start

Right after rooting, I installed KOReader. Sony’s built-in reader is really not great, and it only reads PDF files anyway.

Sony DPT-RP1 Impressions

First, the official specs page: Sony - DPT-RP1

• Screen 13.3
  The large screen is the biggest advantage of this device. It’s only a tiny bit smaller than A4, and it’s amazing for reading PDFs.

• Weight 350g
  Compared to my 10.3-inch Boox device that weighs a bit over 500g, I’m more willing to pick up Sony DPT-RP1 to read (when I’m at home): bigger screen, lighter weight.

• 207 dpi
  It’s a bit worse than 227 dpi on 10.3-inch devices, but the large screen experience offsets it. I can’t really tell much difference with the naked eye.
  Also, besides dpi, things like frontlight, front panel thickness, and front panel material affect display quality.
  Sony DPT-RP1 has no frontlight and uses a flat panel, and it still looks very good.
  For comparison: Boox devices usually have a frontlight and a flat panel, which makes the panel thicker and hurts the display a bit; Kobo Clara 2E uses a recessed panel to reduce thickness and improve display quality (at the cost of collecting dust and looking less clean).
  But in the last couple of years, 10.3 + 300 dpi screens are also gradually becoming mainstream, so you don’t necessarily have to sacrifice screen size for resolution.
  Hope E Ink moves faster and ships 10.3 + 300 dpi panels soon (in my dreams; with no competition E Ink doesn’t need to “move faster” at all, slacking is enough).
