Well that settles the notion that the Coby ICS Tabs (Allwinner A10) are Pre-Rooted when shipped.
It seems that most solutions require rooting. While there are some rooting scripts out there, none seem to be stable (each has some residual problems). Too Risky. May Brick Tablet.
That might not be a problem if we could figure out how to get the Coby ICS Tabs (Allwinner A10) into Recovery Mode in order to revert back to the original if the rooting goes bad.
Ill keep trying to find out how to put the Coby ICS Tabs (Allwinner A10) into Revovery Mode OR find a stable Rooting solution.

I found this site with some more information on Allwinner A10 tablets:

Please hold on as long as you can. This appears to be a really good tablet and a great price. I'm willing to keep trying, if you are willing to hold up before you return.
How much time to you have before you have to Return?

Id rather not send it back. I like it. I just hate the restraits google places on Coby
 
Hi all, new here. Was thinking of picking up one of these tablets but doing research to see if I can get google play first. I found this article. It may help some of you get it working, let me know if it does! Also has anyone played netflix on this tablet, does it play well?

Here is the link, it wouldn't let me put a link in my first post.

Your link refers to a generic process for Coby Tabs that exixted before the new Ice Cream Sandwich _ _42 Tablets. The only reply says that process did not work. I would not try it.
Also, on the first page of this thread, HexDogbone, said the z4root did not work on the Mid9742.
 
I found this on another forum, about getting the tablet into recovery mode.

"I also am having trouble with google play.
Managed to get tablet into recovery mode while plugged in. Any way to root it from there?


Hold volume up button and home button while pressing down power on, released on coby splash screen."
 
Some older (pre-ice cream sandwich) tablets had physical buttons for Home, Menu, Back. The MID9742 has Back, Vol & Power buttons. So that older recovery method wont work --no physical Home button.
-------------------- Try This :
Press and hold .. Back, Power & VolUp for 15 seconds. Recovery mode?
Press and hold .. Back, Power & VolDown for 15 seconds. Recovery mode?
Other combinations ???
 
All,
I created a new thread about 9742 boot issue... my tablet seems to be dead : do you think there is a way to get out this state ? is it possible to boot from a external sdcard ?
thanks...

Hmmm odd. I don't actually have the tablet yet as I am waiting to buy it if it's able to get playstore working. Anyways the thread I got that from is here, and he says it was for the MID7042. I assumed the MID 9742 would be the same just with a bigger screen.

tried it several times volume up and down with above doesnt do anything
 
I got recovery mode to work! The button sequence is as described (volume up + back, whilst holding down power until Coby logo shows up).

Here's a screenshot for proof:

Hopefully now we can proceed!

Netflix does work. Until Google Play works, what you can do is email the APK for the Amazon App Store to yourself. The Amazon App Store contains Netflix and lots of other common apps, though of course the Google Apps are missing, as well as Facebook and a number of big ones. But I was able to pick up 80% of what I needed through there.

Good luck!

WOW --- Can't Believe Something Finally Worked. Great News
Thank You for hanging in there While I came up with all those Crazy ideas.

Turn the MID9742 Off before you try this procedure:

1) Press and Hold.. VolumeUp & Back button ...
2) While still holding above .... Press & Hold Power button. (20 Seconds)
3) When COBY Splash Screen shows, Release all buttons. .... You are in Recovery Mode

REMEMBER: you must PressHold Power Button LAST)

You will see the following Menu:

Android system recovery -- Android system recovery utility

- Apply update from external storage
- wipe data/factory reset
- wipe cache partition
- apply update from cache

The 2nd option (wipe data/factory reset) should restore to factory condition.
