Which bootloader version/branch does your GTab have?
HOW TO CHECK BootLoader Version:
- If you have STOCK Tap-n-Tap: Go to Settings — About Tablet — Tapu UI Version.
- If your firmware starts with “1.0” or “1.1”, then you have the older 1.1 bootloader.
- If your firmware starts with “1.2“, then you have the 1.2 bootloader. (An obvious difference between the two versions of firmware is that the 1.2 branch adds a lockscreen to the tablet.)
- If you have flashed a CUSTOM ROM: It is a bit difficult to determine from inside the ROM. However, the version of ClockworkMod (CWM) will be different. Boot into CWM (Power & Vol + buttons). The CWM version number will be displayed.
- If it displays “Clockworkmod v.220.127.116.11” or “18.104.22.168-bekit-0.8” or if the version number includes “bekit” in it, then you have the version 1.1 bootloader.
- If it displays “Clockworkmod v22.214.171.124 (GTablet 1.2 dev branch, and NI Adam compatible)” or, a newer version, then you have the version 1.2 bootloader.
There is no difference in the hardware using the two different versions of the bootloader. The difference is entirely in the firmware – which can be switched from one to the other. However, the ROM & bootloader version MUST agree.
There are two situations to consider:
- Soft-bricked Devices The term “soft-bricked” refers to a GTab that is locked up at some point (stuck at the 3 birds or similar) and the user has no control.
- Devices that are operating but you want to flash a new (custom) ROM.
[important]Regardless which situation you are in… Or, (if bricked) how the device got bricked… or the bootloader version that you have installed…
ALL users will need to visit “NVFlash for Dummies” to proceed.
NOTE: To determine if your device has the LARGER (250meg) system partition…
To check the size of your SYSTEM partition, open Terminal Emulator app (free on Market), and type in “df” (without quotes) and hit enter.
The “Filesystem” area is at the top of the list (either turn the GTab to portrait mode or scroll up to view the top of the list). Check the line that ends “/system”.
My device (250meg) reads:
/dev/block/mtdblock3 253696 216480 37216 85% /system
If your device shows something around 200000 instead of the 216480, then you probably have the smaller (200meg) system partition.
As always, please leave a comment.
