[Android Q&A, Help & Troubleshooting] MerlinStWahgwaan:
Im hoping this isnt a dead listing and someone out there can help with this....

Im going too post more detailed device info; If anyone knows where I can go online too find the information required for either a stock boot.img or a wiki for devlopment of this device, it would be much appriciated.

Firstly, I posted before accidently in the forum about the other Rand McNally TND series looking for this information, and I want too start this thread off by making it clear, that too my understanding, the TND series is an AllWinner brand device and there is some limited information for rooting that already available, but the OD7/OD8 series devices are, I believe, Foxconn Devices, with Nvida boards, and MacAllan chipsets, accorinding too the droid info report im posting below. Which means they are not done in the same way.

From what I have done to where I'm stuck now;

I have enabled Developer options

I have enabled OEM Unlock

I can use "ADB reboot ....." command, BUT

No matter which "adb reboot" command I send, recovery, bootloader, fastboot, RUU, RRU..... the command "fastboot devices" does not register after the reboot, nor any other fastboot command.

The device simply reboots one of two ways;

It either;

1. Reboots into the "bootloader" or "recovery", which i've discovered is not the bootloader or recovery modes, but acctually a Rand McNallly Engineering Menu, and gives the options for "recovery mode" "fastboot mode" "forced reset".

When you select ANY of these options, if you do nothing but select the option, the device simply restarts, hangs on the RM logo for about 30secs, and then continues too boot the system normally.

2. the device skips the Engineering Menu entirely, hangs on the RM logo, then boots normally.

I have learned that too enter the "Recovery Mode" after selecting it from the engineering menu, you have too follow these directions;

1. Power off the tablet by pressing the power button for 3-5 seconds and selecting “Power Off” on screen. If the device has frozen and will not respond to screen commands press and hold the POWER BUTTON for 10 seconds to force the tablet to shut down.

2. PRESS and HOLD the VOLUME UP BUTTON AND POWER BUTTON simultaneously. The tablet will then boot into the Engineering Menu.

3. Press the VOLUME DOWN BUTTON and highlight the “Android Recovery Mode” option and press the POWER OR VOLUME UP BUTTON to select.

The tablet will then show the Android Robot with a Warning Sign and display “No Command”.

4. Press and hold the VOLUME DOWN BUTTON and HOME BUTTON for no less than five seconds then while still holding them down press the VOLUME UP BUTTON at release all buttons. The tablet should display the Recovery Menu.

If it does not repeat this step until it does. If the screen goes black, start back at Step 2.

5. Using either of the VOLUME BUTTONS, highlight the “Wipe data/factory reset” option and Press the POWER BUTTON to select.

6. Using either of the VOLUME BUTTONS, highlight the “Yes – Delete all user data” and press the POWER BUTTON to confirm. The screen will indicate that the Data and Cache partitions were formatted.

The tablet will return to the Engineering Menu.

7. Using either of the VOLUME BUTTONS, highlight “Reboot System Now” and press the POWER BUTTON to select.

8. Wait for the tablet to complete its reboots.

The tablet will then be reset to factory state

Its the same for fastboot too my understanding, EXCEPT there is a snag I cant figure out;

When you follow step 1 & 2 and get too the Engineering Menu, and try too follow step 3, but selecting "Fastboot Mode" instead of Recovery Mode, you get nothing. either the screen just refreshes and you have too click it again, and the it reboots too the RM logo, hangs and then boots normally, or it just reboots too the RM logo skipping the screen refresh, and then boots normally after about 30 secs.

I assume, like in step 4, where you have a button combo press, like holding two buttons for 5 secs and then clicking a third while holding them at the Android logo, to actually enter proper stock android recovery mode; that there must but somthing I have to do, ether while its rebooting after selecting fastboot mode, or while it shows the RM logo for a few seconds before booting normally, to get it too actually boot into stock android fastboot mode where adb commands will register and I can send the fastboot oem unlock command.

If there is anything I missed, Ill try too add it, but I think thats about it for the current state of my issues.

Below, as mentioned, are the more detailed specs for the device, like I said, if anyone knows where and can point me in the direction of the stock files for this device, or a foxconn or Nvidia wiki or somthing covering this device, it would be BEYOND appriciated.

Thanks everyone!!!
