ChromebookDB Samsung Chromebook 2 13.3 XE503C32-K01US,
Google links: developer information - Samsung ARM Chromeboook, Samsung Chromebook 2, using nv-U-Boot on the Samsung ARM Chromebook, Dev-Install: Installing Developer and Test packages onto a Chrome OS device, Crostini,
2023-08-06: enabled developer mode again - it takes a while. After that, I can do 'shell' from crosh, and 'sudo -i', but 'dev_install' fails with "curl: (22) The requested URL returned error: 403 Forbidden". Oh well.
2023-08-06: charged the machine and powered it on. It still works. ChromeOS is stuck at version 75.0.3370.144.
2017-02-25: update - after restart it runs ChromeOS 56.0.2924.87 (Official Build) (32-bit), Platform 9000.82.0 (Official Build) stable-channel peach_pi.

2017-02-03: I got a "Restart to update" notification, and restarted.
2017-02-03: this afternoon I booted my CB2 after a long hiatus. The battery was empty, I had to log in, log out and in again, because my account was not synced. Now it runs ChromeOS version 48.0.2564.116, platform 7647.84.0.
2015-08-30: after restart it is running ChromeOS version 44.0.2403.156, platform 7077.134.0 (Official Build) stable-channel peach_pi.

2015-02-17: unpacked the machine and opened it up. It came to life, battery is at 68%, claimed 7 hours 5 minutes left. I connect to my wireless network, log in (using Swedish keyboard), configure and select a Norwegian keyboard. I get a "Restart to update" notification.
2015-02-17: I got a pickup message (text message on my cellphone) and picked up the package at my local PIB (Rimi Trondheimsveien) on my way back home from work.
2015-02-16: new InfoCare service portal status at 08:23 local time: it is now listed as "returned". At 16:02 I received a shipping notice with tracking.
2015-02-13: I checked InfoCare's service portal today. the activity is reported as "finished" with "changed battery. tested OK" as solution. We shall see how long it takes to ship it back to me.
2015-02-09: shipping - the package has been delivered (received by "Trond"), it should now be in the hands of InfoCare (the service partner).
2015-02-06: shipping - delivered the package at my local PIB, and got a receipt with a tracking number. The package is now in the hands of the postal service.
2015-02-06: packing - packed in the original packaging, added receipt and fault description, wrapped package in brown paper and put the RMA label on it.
2015-02-06: checking: the account info is secured, there is no microSD card in the slot, the I reset the CB2 by going to Settings, show advanced settings, Powerwash, then restart, Powerwash, confirm. I also reset developer mode. Next, taking pictures of the machine, the power adapter, and the packaging.
2015-02-04: Dustin has registered my Chromebook for service with their service partner, InfoCare.A bit later I received the necessary info from InfoCare for returning the machine
2015-02-03: Another response from Dustin, saying that they don't have a good enough replacement for the Chromebook I have, but they now asks if I want to have it repaired under warranty. I answer yes, please do a warranty repair.
2015-01-26: Dustin responded back, asking if they should find a suitable replacement to offer. The next day, I answered yes.
2015-01-20: I responded to Dustin, stating that a replacement Chromebook needed to be 13 inch, have a good screen and fullHD (1920x1080) screen resolution. Let's see what they come up with.
2015-01-19: Dustin responded to my mail from 2015-01-05 (so, two weeks response time), and asked if I wanted my money back, or a replacement Chromebook since the model I have is out of production / stock now.
2015-01-15: Installing developer packages: crosh, sudo -i, dev_install,
crosh> shell chronos@localhost / $ sudo -i localhost ~ # dev_install
then I used emerge to install sshfs-fuse:
localhost ~ # emerge sshfs-fuse
after that finishes I can create a directory in ~/Downloads, for example ~/Downloads/mpoint and mount remote directories via sshfs. Unfortunately, the files doesn't show up in App:Files.
2015-01-15: version (from "about:version"): Google Chrome: 39.0.2171.96 (Official Build)
2015-01-07: mark the FreeBSD usb stick as bootable to U-boot /ChromeOS: it looks like this:

2015-01-07: enable usb boot - the machine is already in developer mode:
crosh> shell chronos@localhost / $ sudo crossystem dev_boot_usb=1
and verified - done.
2015-01-05: battery - I sent a message to Dustinhome.no explaining about the battery not charging, and what I have tried. I also asked them how they want to handle it. We shall see what their response is, and how quickly they respond.
2015-01-05: recovery usb stick in ChromeOS. First I start a real shell from crosh:

that was a lot.
2015-01-04: recovery media - in Chrome on my Chromebook, I went to chrome://imageburner and got the "Create OS Recovery Media" screen. I inserted a 8 GB usb stick (Kingston DataTraveler SE9), it warned me that all files on the stick would be erased, I pressed "OK". First it downloaded a recovery image (488 MB), extracted it, then started to copy it (1.5 GB) and then said "Your recovery media is ready. You may remove it from your system."
2015-01-04: battery - it seems the battery is not charging. The battery LED is blue (its should be red if charging) and the machine turns off if I unplug the power adapter. I tried a powerwash. It didn't help. When I turn off the Chromebook, the power LED blinks red. I measured the voltage from the power adapter (with my multimeter) - yep, it is 12 volts. I let the machine sit for many hours with the power adapter connected and the machine off - didn't help, the power led is still blinking red.
2015-01-03: I created a Google account. From Settings, Language and input settings, I could select "Norwegian" and Norwegian keyboard.
2015-01-03: first power on. I followed the quick start guide. Plugged in the power adapter, and opened the machine. It powered on, displaying a nice wallpaper and asking me to select language (English), keyboard (Norwegian was not available so I selected Swedish keyboard), connected to my (wireless) network and selected "Continue". Then I had to accept the Google Chrome OS Terms - this screen also had "System security setting" (TPM password) and "Accessibility". Next Chrome OS updated, before asking me to sign in. For now I selected Browse as Guest". After a while the panel (or whatever it is called - status tray) showed "restart to update" so I did.
2015-01-03: the Chromebook 2 has the following connectors on the left side (from back to front): DC input from power adapter, usb 3.0 (chargeable port), HDMI connector, micro-SD card slot. O the right side (from front to back): headset jack, usb 2.0 (chargeable port?), security slot.
2015-01-03: I picked up the package from Dustinhome today, at my local PIB (Rimi Trondheimsveien). The packaging contains:
1 x Chromebook 1 x power adapter (output: 12 V DC center positive, 3.33A) + power cable (the end that goes into the power adapter has the "Mickey Mouse" style plug) 1 x plastic bag with documentation: 1 x warranty information, 1 x 503C12 / 503C32 Quick Start Guide, 1 x Samsung Cromebook "Programvaruguide" (=software guide) which are offers for 1 year free AirDroid Premium + Wunderlist Pro + free lessions in Little Bridge.
2014-12-29: Sale on Dustinhome.no, and I found a Samsung Chromebook 2 (5010782006) for NOK 2490.- and this was the model with a full-HD display, so I bought it.
