-Some roms (particularly the W2 versions) BREAK BlueTooth Headsets. It might get fixed later but for now do without because no amount of factory resets and permissions altering seems to bring it back. The reason is the removed Phone and Telephony APKs which the BlueTooth requires for some dependency.-
So you're using a Quad-core Senai-N10, Ampe-A10 or HiApad-F10 with that awesome Freescale i.MX6q SoC.
And you're unrooted on a stock rom. Here's how to fix that.
Thanks to mickaaa, Kingsman and timmytim along with Bin4ry, CityAceE and Gusse.
This guide is still under heavy revision. I'm dedicating a big chunk of time to testing out every aspect I can of the modded ROM. I want to help the modders and Devs make the MOD as complete and useful as possible. This tablet is so badass it deserves the attention.
What you're gonna need.
-One world's awesomest budget tablet (one of the three quad-cores listed above)
NOTE: Check the Build Number. If it has a W in there get the W2 versions of the recovery and release ROM.
-Root with Restore by Bin4ry. Grab it from XDA
-Recovery image (get the right one for your model's screen. Otherwise your graphics will look washed out and you'll have to start over with the right one)
-Rom release (again, get the right one for your model)
Turn on USB degugging (Settings/Developer options/)
Also allow Unknown sources (Setting/Security/)
Copy the release ROM zip file in the root of your tablet's sdcard (internal storage). You'll be needing it later.
Now let's Root this bad boy (cuz if it ain't rooted it ain't yers!)
Extract Root with Recovery to a new directory and rename the folder 'Root'. Move the 'Root' folder to the root of your PC's HDD. From the start menu Run CMD. This should drop you in a command shell. Type 'CD\root' and hit enter. If you did everything right you should see:
Attach the USB data cable to your tablet, then to the PC.
Type 'RunMe.bat' and follow the instructions.
When all is done your tablet should be rooted.
At this point if you had trouble with rooting consult the XDA thread about Bin4ry's root with restore.
Time to backup! (you can skip this if you don't mind everything being erased for good)
Launch Play Store from the tablet, fill in your credentials and grab a copy of Titanium Root. Once it's done installing run it and then have it backup your apps and data.
Recovery push (you need this especially if you're using a W2 screen device)
Rename the recovery you downloaded to 'recovery.img' and place it in the folder 'C:\Root\stuff\'.
Now you need to go back to CMD to push the recovery to the tablet.
Run CMD. This time type 'CD\Root\stuff' and press enter. You should see:
Type 'ADB push recovery.img /sdcard/'
Good times, now type 'ADB shell'. You should see:
shell@android:/ $ _
Check your tablet and it might be asking to allow shell superuser permission, grant it. You should see:
shell@android:/ # _ (notice the Cash turned into Hash)
Type 'chmod 777 /data'
Then type 'dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p2'
Give it some time to do its thing. When it's done you can exit ADB and CMD (you can close the window) and disconnect your tablet.
Shutdown the tablet and then restart it holding the - Volume button (the right one) as it boots up. You should find yourself in CWM Recovery.
NOTE: If your screen looks washed out and overly-bright with crap contrast then you wrote the wrong recovery to the tablet. Try the W2 version when you repeat the recovery push process above. The next time you go to recovery it should look fine. If you're using the W2 recovery then you also need to use the W2 ROM release.
Finally, ROM TIME. (Because PONIES)
Select 'install from sdcard' in CWM. Then 'choose zip from sdcard'. Somewhere in that list should be the ROM zip you copied over earlier. Select it and let it run. Go make a coffee, chat up the cute girl over IM. Go pinch the mailman's *arse. IDC but find something else to do for the next 5 minutes.
This next step is usually required otherwise you end up with a buggy tablet or boot loop.
If you know for sure you shouldn't do a factory wipe for your particular operation then just skip this.
When it finishes select 'Go Back' a coupla times then have CWM do a 'wipe data/factory reset'. You can also wipe the dalvik cache and fix permissions at this point. When you're ready select 'reboot system now'.
If you made a backup.. (No one likes to lose their apps)
Launch Play Store, fill things out again and grab another copy of Titanium Backup. Have it restore your apps and data. Reboot the tablet and all should be fine with the world.
Congrats on being so awesome!
Special Secret message to people with too much time on their hands:
It is possible to retain BT on the W2 release market fix. But it is long and 'complicated' and really stupid simple.
Just time consuming.
Flash the CWM recovery.
Install the Mod ROM.
Sign on to the market, accept.
Flash the stock W2 recovery BACK.
Install the Stock 1.64 from the extcard but don't do a factory reset.
Since that's the only thing you changed that should be the only item affected.
Right now I'm getting Gusse's help and maybe, just maybe, BT audio will be working again soon. (STILL A WORK IN PROGRESS 4-10-2013)
