[General Questions and Answers] jeremyb234:
Hello All,

This has been the most active forum discussion I can find for the RCA Tablets that I could find. Until now, I've been reading all 28 pages and doing much research. My tablet is the RCT6378W2 Dual Core RCA 7" tablet. I have never rooted the device, enabled usb debugging, or used a custom rom or recovery. One day I was using the tablet, and it stopped, the screen faded out, and it restarted. However, since then, it has not been able to get past the White RCA screen with the dogs on it. I have learned how to access the stock "Android System Recovery <3e>". For anyone who does not know how to do this. I will explain:

1. Turn tablet off.

2. Hold down the volume up(+) key. While holding this, press and hold the power button for about 5 seconds. Release the power button while continuing to hold the volume up key. Within a few seconds, the device should power on with the white dogs. Keep holding volume up key. After a few more seconds, the screen will go black. Keep holding volume up. Then you will see a black screen with a android robot lying down with a red triangle with a ! mark on it. Release the volume up button. In order to access the options, briefly press the power button and volume up key at the same time and release. You should see about 7 recovery options on a list. You can navigate the list by pressing the volume + and - keys, and select and option by pressing the power key (don't hold, just press).

Anyways, RCA will recommend first trying the "wipe cache partition" option. If this doesn't work, then try "wipe data/factory reset" option. After doing this, select "reboot system now". This is as far as RCA technical support goes. If this doesn't work, they will give you a ticket # and instructions to send the tablet to Venturer Electronics in Lockport, NY for repair. Part of the problem is that RCA has not released the firmwares for this unit. They claim to not have it. They might be right, as the tablet was made by Foxconn International. Anyways... Venturer Electronics claims to not have the firmwares either, so I don't know what they think they can do with it besides replacing hardware. Anyways, because my unit still powers on, the screen works, and recovery system is still workable, it seems like there should still be some small chance of getting this to work.

I have tried nearly everything. I hardly know what I'm doing, but all of the instructions I've found do not work. I've tried downloading other firmwares that should work, and they never do. I have managed to connect my device to my computer and communicate with it via ADB (one of the options on recovery system). I have also attempted to flash these roms via micro SD card, but have always been rejected after failing verification. The only thing I have had any success in was installing some update files that someone provided a dropbox link to. These files were 1.0.2.zip , 1.0.3.zip, and 1.0.7.zip. All three of these firmware files have been accepted and successfully applied to my tablet via ADB. To my knowledge, these firmwares are not complete android roms, but are actually updates that were provided to the RCA tablets.

This brings me to my final thought (sorry for all the back story...). Because these update firmwares are the only ones that seem to be accepted by the stock android recovery system, is there any way to alter them to include the rest of the android operating system? I have heard about tools that can repackage these update files to include virtually anything you want. However, I have tried repacking these updates as is, and the new update.zip fails verification. So, I think that there must be some way to manually alter these updates. Perhaps, maybe this is not possible. What do you think?

One last thing, if there is anybody out there who has successfully recovered this tablet from a non-booting state to a functional android operating state, please tell us how you did it! If anyone out there has a working firmware for these tablets, please post! (You can send me a private message too!)
