Coby 7048

[RasputinAXP]

With my 8048 running sluggish. To fix do a system reset? Will this wipe my root? I really don't wanna do the whole process again lol

See my previous post. Do a system reset, and because you've pushed root to /system it'll stay rooted. You won't need to go back through the process unless you did it wrong initially.

Status update: the 7048 will actually run Minecraft PE, which is great, because it'd be a dealbreaker if my sons couldn't play it. It's plenty responsive, just change the settings to low graphics and you'll be fine.

If you will boot to fastboot mode, I will help you fix your tablet.

to get into fastboot mode

reboot tablet as soon as you seen coby press and hold volume up count to ten

now as admin open terminal fastboot devices

 

[Traveller]

Would that work for all the Generation 3 tablets, or do the tablets with Allwinner and VI Micro processors have a different key combo?

 

[neo_stythys]

'Volume Down' goes into recovery mode, but 'Volume Up' just makes it stay at the 'COBY' bootloader. As far as I can tell, the 7048's don't have fastboot. Being a telechips device, I would assume FWDN would work, but have not tried as of yet.

That is correct it should stay at the word Coby now type the fastboot devices command like I asked you to.

If you don't have drivers setup read this. http://www.androidtablets.net/forum/lenovo-ideatab-a2109/51074-howto-a2109-fastboot.html

VI Micro processors I think it's adb shell reboot bootloader

Allwinner custom script like the reboot-recovery script

 

[martin73x]

I´m finally in fastboot mode.
How can I fix my 7048?
