Installing OMA ROM On Insignia Flex Elite 7.85

bobb has posted instructions at the ARCTablet forum.

Quoting (with some link additions):

Here’s what I did to get the rom installed:

1.Go to http://forum.xda-developers.com/android/apps-games/one-click-root-tool-android-2-x-5-0-t3107461 and download KingRoot and install it and open/run it then restart tablet.

2. go to playstore and get esfile explorer, terminal emulator and busybox and install/open them (you want to give them super user access when it asks)

3. Download Oma’s rom to your windows machine and unzip it.

4. plug a micro sd card into your windows machine and copy resource.img, kernel.img, boot.img, recovery.img and system.img from Oma’s unzipped rom onto the sdcard. Update December 31 2015: The microSD card should be formatted to NTFS for the tablet to “see” it in Step 6!

5. take the microsd card and plug it into your tablet, turn tablet on.

6. Using esfile explorer, copy the above files onto the sdcard in your tablet (not into a folder on the sdcard, just the sdcard itself)

7. Open terminal emulator, type in ‘su‘ without quotes and hit enter.

8. you will see a # at end of the next line (means you have super user access)

9. type in ‘dd of=/dev/block/mmcblk0p3 if=/mnt/sdcard/resource.img bs=4096‘ without quotes, hit enter (it will say it copied a file across for all of these as you do them, system.img will take some time)

10. type in ‘dd of=/dev/block/mmcblk0p4 if=/mnt/sdcard/kernel.img bs=4096‘ without quotes, hit enter
11. type in ‘dd of=/dev/block/mmcblk0p5 if=/mnt/sdcard/boot.img bs=4096‘ without quotes, hit enter
12. type in ‘dd of=/dev/block/mmcblk0p6 if=/mnt/sdcard/recovery.img bs=4096‘ without quotes, hit enter
13. type in ‘dd of=/dev/block/mmcblk0p10 if=/mnt/sdcard/system.img bs=4096‘ without quotes, hit enter

14. Tablet has Oma’s rom installed, restart it.

15. KingRoot will let you turn off some things at start (Auto-start), I uninstalled Purify (in KingRoot).

16. I also installed droidwall to stop apps from accessing internet as KingRoot tries to contact some server sometimes.

Hope this covers it…

Many thanks to Oma!

Thanks to bobb, OMA, and others who have gotten everyone to this point.

    I ran an mp4 movie on loop (the file was on my external sd card) with brightness set at 50% and volume off and wifi turned off and the movie ran for 5.5 hrs.It took 2 hours to drain the last 20% of battery life. Don’t know if this is a good test?
    Overall, I believe battery life is better, I get about 4+ hours surfing the net, etc.
    On standby, with the Advanced Wifi Scanning always available turned to Off and Keep Wifi on during sleep turned to Off and Network Notifcation turned to Off, over night (10 hours) battery only decreased 5%.
    This was the first time I totally drained the battery, expect it will be a little better now (everyone says to totally drain battery at first).
    I opened up the tablet and the battery is a 4000mah 3.8V, 2.5 Deep x 119 Length x 112 Wide.

    Step 14 should say tablet has Oma’s rom installed, restart it.

    Netflix not working, just stays at loading…
    Camera ZOOM FX does a little better job of photos.
    Can read and write to sdcard (it’s formatted ntfs).
    Seems to boot faster with some of the telephone stuff removed, and others disabled (Hangouts, etc.).
    The only way to keep root for terminal emulator is to re-install busybox after each shut down.
    Ordered a battery from aliexpress, will be a few weeks before it arrives.

  4. HI folks. I’m having difficulty copying over the system image. I keep getting the error “No space left on device”. Any advice?
