Minimum Brightness + Turn Off Button Backlights on rooted Android.

Hello again, yes it's another app. I'm not really good at (or not interested in) the interface. So it's ugly af. Yet functional af too. :) It just does the job unlike many other fake backlight apps or screen overlays. This is not an overlay, it changes your screen brightness to the lowest possible level your screen allows. If you ever need more, you better use an overlay. Because this is the lowest. And it really can turn off your button backlights.

Needless to say, it needs ROOT. --> Root your Dialog Optima 2 here..

In case it doesn't work on your device, just leave a comment with a file explorer ( or even better shell ls -l ) screenshot of "/sys/class/leds/". I'll give you a fix asap. Even better, see the source below. :)

Dialog Optima 2 Unstable SuperSU Fix/Workaround

The title says it all, this is not a permanent solution. Just a workaround until Chainfire fixes the SuperSU to work with these newer China devices. If your device is stable and all, please don't proceed. Though this is for DOptima2 A130, it could work on other rooted L5.1/22 devices. If your Optima2 isn't rooted yet, get it rooted.

Till SuperSU is fixed, we'll use ToggleSU, a little apk I made to toggle "suability". It doesn't offer any advanced features you get from SuperSU or any other superuser apk. It doesn't even prompt you if an app asks for permission. To toggle su is all ToggleSU can do. Before proceeding any further make a full backup of your device. Just backing up /system/xbin/su would be enough, but I can't guarantee anything.

Unzip this archive to /sdcard/togglesu
This is NOT a flashable zip, it just contains some files that we'll be using to install ToggleSU.

Then connect your device to an adb configured computer. Avoid trouble, use Linux. :)
Open an adb shell, then issue the following.

su

and ONLY IF this succeeded and you got a root shell like the image below, continue. Otherwise, you have either denied SuperSU or your root is broken. Get it fixed first.

Disable SuperSU using Settings > Apps > All > SuperSU > Disable
(Yes disable it, we won't be needing it anymore)

Now in the root shell, issue the following.

cd /sdcard/togglesu

chmod 751 installsu

./installsu

If it returned nothing, you're ok. Otherwise, something went wrong. Restore from backup if necessary.

Now exit the root shell, and disconnect the device from the computer.
Open your file manager, install the apk in /sdcard/togglesu/

If everything went alright your suability should toggle when you press the Toggle button. Test it a few times using the adb shell, or terminal emulator.

Unlike SuperSU this cannot prompt you when an app asks for root access. Instead you'll have to toggle the lock before running that app.

It's still a beta, so... tell me if anything goes wrong. Such simple app can't go wrong but you know.. :D

PS: A root app should be opensource, so does everything else. Here's the source.
PPS: Delete the /sdcard/togglesu folder if you don't need it anymore.

Dialog Optima 2 Custom Recovery + Root

Well peeps, it hasn't even been a month since the phone was released but as I had access to a pre release device, I had some more time playing with the device. This device however was a slightly different story when it came to rooting. After trying almost all the one click root apps and windows software (damn I even installed Windows on a 70GiB partition on my precious Linux box. :/ ) I kinda “knew” this cannot be rooted that way. The only option seemed to be compiling/porting a custom recovery and flashing root zip using the recovery. Again, no auto port worked and when I've finally found a link to the original compiler and asked him for help/advice his reply was something like “There's a problem with some mt6580 devices” and that's that. So I had to do a manual port/compile. Compiling a recovery was kinda out of range as I'm running so low on space.

So I HAD to port, manually. But with what? There was almost no device that fits the device specs/build version etc. The Doogie X5 was kinda OK but I didn't go anywhere farther than a bootloop with that. So I kept searching and searching for like two weeks. And after crawling through almost every China phone forum and with the use of some Google dorks, I found two devices with the exact custom build. (Lucky me eh?)

Fly FS504 Cirrus 2 and Nomi i504. And now I had to find if anyone had compiled a recovery for any of them. The thing was, the forums were in Russian. So with “excellent” Google translate I finally found a TWRP for the Nomi. A little play with the props,fstabs, init.rcs and the kernel, voila!

Yeah yeah I know you don't wanna here my story but just DEAL WITH IT!

Now to the actual thing.
Configure adb, fastboot on your machine. Ubuntu/Aptitude users, do (I know you already have these but in case you don't)

sudo apt-get install android-tools-adb android-tools-fastboot

And fix the udev rules. Don't forget to restart udev.

Windows users? Use Google.

Enable USB Debugging and Unknown sources and toggle the “Allow OEM Unlocking” option. Now check if adb and fastboot work.

Fire up a terminal, do some stuff like

adb reboot bootloader
 fastboot reboot

Before flashing anything we need to unlock the bootloader, do,

adb reboot bootloader
fastboot oem unlock
#if this doesn't work try fastboot oem unlock 0x0e8b

Once you've unlocked the bootloader, flash the recovery.

fastboot flash recovery recovery.img
fastboot reboot

When rebooting hold Volume Up + Power. You will see the “Punisher” face and then taken to the TWRP. If this doesn't happen, you fucked up somewhere. Figure out where you did wrong, fix it.

Now to the actual rooting, though TWRP has its own rooting functions it's a little messy and broken. So we'll flash the superSU.zip manually. Do,

adb push superSU.zip /sdcard/

Then in the recovery INSTALL >> select “superSU.zip” >> slide to the right.
Once it's done, wipe cache partition and reboot. And congratulations, you got yourself a rooted device. Use Root Checker to check root.


NOTE: Even the superSU is not so compatible with the device yet. So we cannot use “Prompt”, until it's fixed we will have to use “Grant”. Other superuser applications didn't even work. So if you got anything better, please tell us. :)
