I want to use this table for car navigation and I`m unable to enter fastboot to perform the command fastboot oem off-mode-charge 0 to autoboot on USB power when car starts the engine.
ROMs uploaded on Dev-Host server ... No bugs except USB OTG and extra Language support, sorry about that
Please remember to back-up your "/data/nvram" folder from your stock before flashing and replace after flashing these so that you all don't use wrong IMEIs, MAC addresses, Serial number etc. Also do all three wipes before flashing (data, cache and dalvik cache)...And yes, be patient cause the first boot after flashing may take up to 3 minutes...
All files posted here are to be flashed using CWM recovery with "Install zip from sdcard" option !!!
NOTES :
1. For complete power-off in LeWa modded ROM, you have to un-check "settings--->Accessibility--->Quick Boot"
2. May have to install the patch (link below) to set internal sdcard as default memory after flashing modded Foxtrot and LeWa ROMs
EXTRAS : (Credit Foxtrot_KZ)
Patch for setting external sdcard as default memory : http://d-h.st/SDL
Patch for setting internal scard as default memory : http://d-h.st/u5M
Sure, no problem !
After several hours of search and difficulties to register onto Chinese websites
I managed to find the attached file. I take no credit for the tool because it was developped by someone else (SNARL I guess)
It was missing the superuser apk inside so I put it back and also translate the steps to English.
Here are the steps :
- Connect the tablet in Debug USB mode
- Launch root.bat
- The device will reboot at each of the 3 steps
1. Open SP Flash Tool
2. Choose a "Scatter-loading" file from "CWM Recovery ROM" folder
3. Press "Format" in a left top corner of SP Flash Tool
4. Choose "Auto Format Nand Flash" -> "Format whole flash" and press "OK"
5. Connect device to PC, press "reset" button on a back of your device
Your device should be formated on this point.
6. Close SP Flash Tool

Do the same think with gapp-ics.zip and reboot your device.

On this point you should have a IMEI working, if not repeat IMEI repair from point 3.
