SliPer ModRecovery and G1310 RootROM. What are they?

SliPer ModRecovery is a custom Andriod system recovery. G1310 RootROM is a custom ROM for Gigabyte GSmart G1310 smartphone with Dual-SIM support. Several versions of G1310 RootROM correspond to different builds, each designed for a specific region or reseller.

What are the differences between SliPer ModRecovery and stock recovery?

The only difference between SliPer ModRecovery and stock recovery is that during ROM installation process Gigabyte signature verification is disabled in SliPer ModRecovery. So you're able to install any stock/custom ROM (suitable for your device). The only restriction, while installing stock ROM (not custom!), is that BUILD_SW_PROJ field in update_ver.txt file of already installed ROM and BUILD_SW_PROJ field in update_ver.txt file inside update1.zip/update.zip package on SDCard should be equal.

What are the differences between G1310 RootROM and stock ROM?

In general, a custom ROM may differ from a stock ROM in everything ranging from the custom user interface to the modified kernel.

These are the differences of G1310 RootROM comparing to the stock ROM:

disabled BUILD_SW_PROJ check in the update script;

ROM is already rooted;

added BusyBox 1.19.4;

adbd runs with root permissions and "USB Debugging" is turned on for logging of the boot process by default;

G1310 RootROM preserves SliPer ModRecovery on ordinary boot for further use (if stock ROM is installed, on each ordinary boot recovery partition is being rewritten with the original recovery image formed by patching original boot image with binary diff file recovery-from-boot.p).

Interface and kernel are derived from the original ROM.

Will I lose the warranty after installing G1310 RootROM by using SliPer ModRecovery?

Before calling for service install G1310 RootROM for your region, then install original ROM for your region. This is required to restore original ROM and recovery. After that clear cache and erase userdata by using stock recovery, remove SDCard from the device.

How to install G1310 RootROM?

NO userdata will be erased during G1310 RootROM installation process, but it would be better to backup your valuable data anyway!

You should install smartphone drivers if they haven't been installed yet.

It's important that you DON'T need root privileges to install G1310 RootROM by using SliPer ModRecovery.
