1. What to Do Now?


GomdoLight is just enjoyable, and you have probably configured most of it already during the installation process, but it can be better adjusted to your needs.


1.1. Donate to the Developer

If you are satisfied with GomdoLight, how about making a small donation?

Any amount will be greatly appreciated. (You will need a PayPal account)


1.2. Remove leftover apps

Though GomdoLight has eliminated all unnecessary apps from your system area when it is installed, there might be some leftovers if you updated those apps at least once. However those leftovers can now be completely removed because they are no longer a part of the firmware. Go to Settings → General → Apps, and remove whatever you do not want.


1.3. Root or unroot your device

You might want to root or unroot your device. For example, if you installed GomdoLight via the Sideloader directly on the unrooted stock firmware GomdoLight remains unrooted, and you might want root. Or, if you rooted your device to install a custom recovery environment as a required preliminary step before installing GomdoLight though you didn’t want root, then you might want to unroot your device. Either way, this is now the easiest task in the world with GomdoLight.

– To unroot, use ‘disable.root’ Flag.

– To root, use ‘enable.root’ Flag.

Detailed information on using Flags can be found below.


1.4. Install some powerful apps

GomdoLight App Manager offers some very useful apps that might help you in various situations. These apps can be installed without any network connection, and can be freely removed when you no longer need them. Whenever you upgrade GomdoLight to a new version, check the GomdoLight App Manager for new apps and updates. You can also open this manual any time from its menu.


1.5. Further personalize the device with GomdoLight Flags

GomdoLight gives you an unparalleled level of freedom in personalizing your own device. With ‘GomdoLight Flags’, you can do many great things even without root. Please refer to below.



2. GomdoLight Features


GomdoLight has numerous features to further adjust itself to your needs.


2.1. GomdoLight Flags

Inside GomdoLight are very powerful features that you can use by placing specially named files in /sdcard/GomdoLight, then restarting your device. In other words you are ‘signaling’ GomdoLight to perform specific tasks by creating files with specific names. These files are called ‘GomdoLight Flags’. Being able to use the Flags, is often one of the primary reasons why thousands of users choose GomdoLight.

Some of these Flags are listed below.

  • enable.root
    Roots the device without any external help.
  • disable.root
    Completely unroots the device. You will be without root privilege until you root the device again with ‘enable.root’ Flag.
  • install.xposed.framework
    Installs the Xposed Framework, regardless of whether the device is rooted or not. Requires the ‘Xposed Installer’ app to work properly.
  • auto.install.xposed.framework
    Automatically schedules for installation of the Xposed Framework when the device starts without the Xposed Framework in place.
  • uninstall.xposed.framework
    Uninstalls the Xposed Framework.
  • disable.adblock
    Disables the built-in ad blocker. Useful when some apps or websites do not work properly.
  • enable.adblock
    Enables the built-in ad blocker.
  • reboot.recovery
    Reboots into the recovery environment.
  • gomdolight.online.upgrade

  • force.gomdolight.online.upgrade
    Downloads and installs the latest version of GomdoLight, regardless of current version.
  • disable.gomdolight.online.upgrade

  • clear.carrier.wifi
    Removes all predefined SKT/KT/LGU+ Wi-Fi network entries.
  • disable.3rdparty.camera.sound
    Silences most (but maybe not all) 3rd-party camera apps. Stock camera app is not affected, and can be muted without this Flag.
  • enable.3rdparty.camera.sound
    Unmutes 3rd-party camera apps silenced by ‘disable.3rdparty.camera.sound’ Flag.
  • install.busybox
    Installs BusyBox to /system/xbin, and creates symlinks for all its applets. Recommended for advanced users.
  • install.busybox.nosymlink
    Installs BusyBox to /system/xbin, but does not create any symlink. Recommended for advanced users.
  • uninstall.busybox
    Uninstalls BusyBox from /system/xbin, and removes all symlinks for all applets.
  • disable.security.app
    Disables the preloaded antivirus app to further optimize the system. Not supported on every device.
  • enable.security.app
    Enables the preloaded antivirus app to have an extra layer of security. Not supported on every device.
  • restore.easymod.backup
    Restores the system from the EasyMod backup data set, letting you undo the changes made by the EasyMod package recently installed. However, this Flag does not remove any components that are newly added (without replacing the existing components) by the EasyMod package.
  • clear.easymod.backup
    Deletes the EasyMod backup data stored on the system by previously installing an EasyMod package. This action is irreversible.

For more details on GomdoLight Flags, refer to the ▷ tutorial for using GomdoLight Flags. For an additional list of GomdoLight Flags and their functions, read the supplementary document for LGE devices or SEC devices.


2.2. Silenced Camera

Now that you have GomdoLight installed on your device, the preloaded (stock) camera app can be silenced. Shutter sound can be silenced by turning it off from the settings menu, or on some devices, simply setting the device to vibration or silence mode. (NOTE: This feature is not available for some devices, e.g. Pantech Vega Iron 2)


2.3. Other Features

GomdoLight has several features that will silently aid you in some situations, or remove clutters and optimize your system. These features work automatically, so you can just focus on what you really want to do, without having to care about them.



3. Troubleshooting


Though it is the most desirable if you find GomdoLight useful and use it without any problems, sometimes unexpected bad things might happen. If you’re unfortunate enough to experience those bad things, don’t worry. Most problems can be solved.

  • Restart your device
    First, restart your device and wait for two or three minutes. This solves most of the problems. If your problem persists, proceed to the next step.
  • Search for forum threads
    The ‘problem’ might be actually an intended behavior, or might be so common that it is already answered. Search the forum thread before asking a question, and it is quite likely that you will find the answer even before asking. If your problem is not answered in the forum, proceed to the next step.
  • Uninstall 3rd-party components affecting system behavior
    There may be some applications that might affect or alter how your device behaves, including, but not limited to, battery savers, task killers, and tweaks. Uninstall these and see if your problem is solved. If your problem persists, proceed to the next step.
  • Repair and initialize GomdoLight
    Run the GomdoLight Installer, and repair GomdoLight by selecting ‘Upgrade/Repair’ to reinstall the GomdoLight core files. If your problem persists, run the GomdoLight Installer again, and initialize GomdoLight configurations by selecting ‘Troubleshooting’, then ‘Initialize GomdoLight’. This will reconfigure GomdoLight to near-stock state. If your problem is still not solved, proceed to the next step.
  • Clear damaged or incompatible data
    Run the GomdoLight Installer again, and select ‘Troubleshooting’ from the main menu. But this time, select ‘Clear Damaged Data’, and check the ones that you suspect to be damaged. WARNING: SELECTED DATA WILL BE PERMANENTLY LOST.
  • Completely uninstall GomdoLight (revert to stock) and reinstall from scratch
    Completely uninstall GomdoLight, then, reinstall GomdoLight from scratch. * NOTE: If you confirm that the problematic behavior is not observed anymore after reverting to stock firmware, maybe there is a flaw in GomdoLight – report the issue to the forum. However if the problem persists even with the stock firmware, the problem might be in the stock firmware itself (in this case the problem may be unsolvable), or somewhere else, such as corrupted user data.
  • Perform a factory reset
    If the problem still persists, back up everything, make sure you have your backup data stored in a safe place, and perform a factory reset.
  • Ask a question
    If nothing works, now it is the time to ask a question. Post a thread, but please be polite, and try to ask as thoroughly as possible.

* NOTE: Do NOT try to contact the developer via PM, email, or anything ‘private’, unless you’re requested to do so by the developer. Private questions, no matter how important/urgent they are, WILL BE IGNORED.



4. Uninstalling GomdoLight


Though it is generally not a wise decision, but for some reason you might want to uninstall GomdoLight. To uninstall, just flash the stock firmware, then factory reset your device.
