New versions of CM10 (Jellybean) are now available for the Polaroid PMID4311 and Emerson EM543. The Polaroid version should be compatible with its Uniden-branded cousin.
These fully rooted ROMS are based on a build by Shaun2029, and include these apps: PlayStore, Gmail, SuperUser, Apex Launcher, ES Explorer, Root Checker, and KoiPond live wallpaper.
Unlike previous DoPa ROMS, this version comes in two parts so existing users can upgrade without losing their apps and data.
- a LiveSuite image that is required if you are using the stock ROM. Current DoPa ROM users can skip this step.
- an update zip containing CM10 that is installed using CWM.
There are separate files for each tablet:
- Polaroid PMID4311 (4311-cm10-dopa-20130101.zip and 4311-dopa-framework-20130108.zip)
- Emerson EM543 (543-cm10-dopa-20130101.zip and 543-dopa-framework-20130108.zip)
Also available from the Polaroid link is a zip with all the apps that were preinstalled in the two tablets' stock ROMs.
Part 1 - LiveSuite image (xxxx-dopa-framework-20130108.zip)
This is a one-time step that is needed to expand your /system partition from 256mb to 384mb. Without it, attempts to install the update zip will fail for lack of space. It will also install an updated version of CWM 188.8.131.52 in your Recovery partition.
After LiveSuite finishes, the tablet should reboot automatically. If it doesn't, then restart the tablet normally - do not try to boot directly into CWM. On this first boot, the tablet will display the DoPa logo for about 10 seconds while it formats your /data, /cache, and /sdcard partitions. When done, it will reboot into CWM so you can install the update zip.
If you haven't used LiveSuite before, you can get it, along with instructions on using it, from here: LiveSuite.
Part 2 - Update Zip (xxxx-cm10-dopa-20130101.zip)
Copy the update zip to an SD card, insert it, then select "install update from SD card" from the CWM menu. Alternately, you can use ADB to push the zip to your internal SD card (a.k.a. /emmc). In either case, the update program will erase anything on the card, so backup any existing content. If you are upgrading from a previous DoPa ROM, the update will clear both /cache and /data/dalvik-cache - you shouldn't need to do anything manually. When done, hold the power button until the tablet powers off, then press it again to restart normally.
it takes several minutes from the time you restart until the first screen appears - most of that time is spent in the CyanogenMod boot animation. Be patient. After it's up and running, the tablet will be very sluggish; its performance will improve noticeably after some use and a reboot.
If this is a first-time installation, you'll get a Setup Wizard which may not be able to identify any wireless networks. If you know the name of yours, you can select "Other Network" and enter its name - otherwise, you can back out of the Wizard and setup your WiFi and Google account later.
Compatibility & Bugs
The very newest Polaroid 4311's may actually be Emerson 543's in disguise - there's no way to tell from the outside. If your touchscreen stops working after flashing the 4311 version of the update zip, try the one for the 543.
This ROM should fix problems with wifi draining the battery when the tablet is asleep.
After installation, some stock apps may be larger than the screen because they were designed for higher resolution screens. A work-around for this was identified after this version was released: edit /system/build.prop and change 'ro.sf.lcd_density' from "120" to "96".
