Until finally I could release 50MB-60MB of memory on the XT550 !!! here the guide as I did .... First of all come to this cost me several reflash to the XT550.
Before starting I recommend to later retrieve synchronize contacts, calendar entries, and other ...

RSDlite search in XDA
open the program and wait for usb recognize
click in the button next to filename text frame '...' and select the firmware file

How to remplace the chinese super user by SuperSu from @Chainfire
Thanks to @Chainfire (my respects)
https://play.google.com/store/apps/details?id=eu.chainfire.supersu&hl=es_419
1- We go to the Google Play Store and downloaded SuperSU
2 - Once downloaded and run it SuperSU we get a screen that says upgrade binaries we touch 'Normal Mode' If the option doesn't work normally , and past 5 minutes (or more) just restarts and retry.
3-Then go to the "Settings" tab and look for the option "default access" and select "Prompt"
4- done this one you see what we will do is install SuperSU in the System folder and Chinese superuser will be deleted leaving for default SuperSU so go where it says "SuperSU installed in / system" asks you a couple of confirmations and if we give the entire phone was restarted and when we turned on the Chinese superuser is deleted and will be installed SuperSU
thank you and excuse me for not putting images is that I was afraid that SuperSU uninstalling and then reinstalling it and take pictures of screen, Root lose but I think the tutorial is quite understandable.

Drawline test solution to the touchscreen calibration screen
DRAW LINE TEST
this issue would not wish on my worst enemy. That let me several nights without sleep and in some moment want to smash the phone to the wall or break it with a hammer (thats the reason of the image above). ok too much bla bla, go to the point. browser by the web (spanish forums because it's my native lenguage and the phone is a masive plague here LOL) I find a solution to this issue (lucky phone It's saved from the hammer).
this one is the drawline test, it's a test which calibrate our touchscreen from the issue of the keyboard mistake letter touch and the crazy recent screen ('pantalla loca' how the follow tuto reads LOL) I don't what this apk do but follow the video steps and you will fix it.
https://www.youtube.com/watch?v=DCxWx-hW0EM

Last step leave stable, and free memory for more apk's
Install Root Explorer, Go Launcher EX, Link2SD, CacheMate and DroidTweaker (you can install apps from Google Play or download them and copy them to the SD card) - started in Link2SD and select EXT2 (you must partition the SD before) - Configure Ex Go Launcher as the default launcher ... Preferences .... Set as default launcher and opens the contextual menu if using always ... (this step is very important because if they are left without launcher to make the next step) - Open Root Explorer and go to / flex / app .... touch where it says Mount R / W .... select all files in that folder and give them move and took them to a new folder inside the SD card. .. There are 2 apps that give error loop if you move it ... give here a while to force close and finally restart the phone .... we will miss several apps ... but do not worry. .. when we started again ... Root Explorer to / sdcard / (folder where you moved the content /flex/app)...
install FileManager.apk
MusicDashboardGlobal_argospin_mdpi.apk (controls the PLAY button)
MusicGlobal_argonspin_mdpi.apk (music player) ...
and if we have Facebook (FBAndroid_1.8.3-preload.apk)
or Talk or Gmail or YouTube or Twitter (I recommend installing the apps that came with the phone and then the update. .. as some gave me error when installing from Play)...
finished installing apps open the DroidTweaker (we ask permission of SU and various checks to make sure we know what we do lol) ...
check Clean Dalvik and give Dalvik Heap Size 40M ....
Apply and restart the phone
- Restarts and go to CacheMate ...
choose it clean and there we see how much memo is .... in my case before updating 84MB at this point we can load apps that we like in the phone ...
in my case install Shazam, Whatsapp, Wifi File Explorer, Dolphin Browser, File Transfer Bluethoot, Notifications and Navitel do .... after we verified that we have not been any updates the Play.
- We again use the CacheMate and ready I stay with 52MB available ... the phone is more fluid than before ... it does not lock and has more resources available ... yet updated and synchronized ... I still test the theme the battery to see how hard without batterymanager I hope that works for someone else ...
Update: in this 4shared folder is all apk and the batery mannager if you want to equilibrate your batery.
you can use batery calibration too.

[MOD] Fonts or Font style letter O JB KK
I'm customizing and sharing mods and Apps for the XT550, these sources of letters are best for use with behaus letters or something XD, The question is going to Settings / Display / Sources of letters and no change for behaus or as call.
1 - You have to be root.
2 - Have root explorer.
3 - Make a backup of the Fonts folder located in the System.
4 - Download the files.
5 - Then they go to System / Fonts and paste the downloaded files.
6 - replaced.
7 - Restart the device.
8 - And ready, the lock screen stay more minimalist .. So:
In short, it is much, much more cute ah, and greatly improves if you put the source of behaus letter.

Ulefone power 3s problem

First post so I apologise if I'm posting in the wrong area. I have a rooted ulefone power 3s and having a strange overlay on my screen. It's in red and is located top right of the screen but isn't present on lock screen and when reboot is performed the writing takes roughly a minute to appear. The writing reads:
未写入key
I've tried translating it but cannot find anything at all for what it might be. I'm running on 7.1.1 both IMEI are present and correct and phone works fine other than this issue. It appeared after I flashed my rom (official ROM from ulefone website). All my data was wiped and I lost my IMEI etc I've managed to sort IMEI but really struggling with what this writing is any help at all would be muchly appreciated.

Google translate says "not written key" - which is not really explaining too much.
You can go step by step to isolate the root cause of the message like:
- Shutdown the phone and remove all SIM cards and external SD cards
- Start up the phone and see, if the message is still there.
- When exactly does the message appear? ....and so on.
Anyhow - this will probably not fix the issue.
I would restore the original ROM or (even better) download the Oreo ROM from the Ulefone download area:
It's available in the download area for this phone
Good luck!

I had the same issue.
The setup is possible with this screen problem, so just do it and then you get a notification about a new OTA Update.
Go ahead and install this, it will fix the screen, but you end up having the same red overlay with the chineese writing.

I found out how to ged rid of the red overlay!!!
It's a service called "sdrpmbFloat view service"
Killing it via developer options -> active services hides the overlay.
So if you have root, you can simply disable this service, or be able to uninstall the app behind this service.

Hello,
i found 3 ways so far to remove it:
1. Killing the "sdrpmbFloat view service" (overlay will be gone since next reboot)
2. Disable permision to show over other apps for Factory Mode:
Settings --> Apps -> 3 dot menu, Show system --> Scroll down to Factory Mode and select it --> scroll down to advanced section on bottom --> select "Draw over other apps" and switch it off.
3. With root, uninstall Factory Mode app

APP PAROU
Acabei de comprar meu Ulefone Power 3S, mas ele fica parando os aplicativos do android: "Google Play Services parou ou "Google Play Services isn't responding" e logo em seguida reinicia sozinho. Não dá para mexer. alguém sabe por que isso acontece?

Delete package
This method worked for me to get rid of the 未写入 tee key message. With adb platform tools use this command line :
adb shell pm uninstall -k --user 0 com.mediatek.factorymode
It deleted the factory mode package and stopped displaying the message.

not Turn on
I was using it normally when I turned the screen off and when I put the fingerprint it did not turn on.
Does anyone know what can it be? I'm suspecting the battery.:Boa:

A simple way that works for me was restaring the device in Safe mode (hold power botton, when te options of shut down and restart appear on the screen
press the shut down botton on the screen then you going to see a dialog and confirm to reboot to safe mode) in ideveloper options disable: Enable view atrribute inspetion, reboot and its done! :angel:

4. Option is to deinstall the Factory Mode App using ADB/SDK Tools with PC but Without ROOT
All you need to do is Download this: www,mediafire,com/file/cc443705xa3e6mg/minimal_adb_fastboot_v1.3.1_setup_2.rar (remove the comm between www,mediafire,com and set points instead for the commas....... because new account and i cant write links)
U must enable USB-Debugging on your Ulefone Power 3/3s. (no matter which Android version)
Connect your Smartphone with your PC using USB Cable.
Then start the Program you downloaded before.
Maybe you Have to Confirm the Debugging on your Smartphone.
1. Type into the Console:
adb devices
Something like this should pop off:
C:\Program Files (x86)\Minimal ADB and Fastboot>adb devices
List of devices attached
0123456789ABCDEF device
2. Type into Console:
adb shell
Something like this should pop off:
Power_3S:/ $
3. Type Into Console:
pm list packages
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
All the Packages you Have installed should Pop off.
4. type Into Console:
pm uninstall --user 0 com.mediatek.factorymode
"Success" should Pop Off
If this Worked you Restart your Phone and The Red 未写入key or 未写入tee key should be away 4 ever.
I hope it Works and sorry 4 my bad English.

I dunno if is the same thing but I got the same message when I updated my Power 3S to Oreo... so I used an ADB command and removed that message. You may try it if you want, but I can't guarantee that it will work for you... or anything but do it at your own risk: adb shell pm uninstall -k --user 0 com.mediatek.factorymode

King !!!! thanks a lot, i have been searching for this for more than 2 months!!!
method 2 worked perfectly for me, thanks again !

I remember I have rooted Ulefone power 3s with Android 7 a year ago.
Now I have Ulefone power3s with Android 8 and I cannot
I go to fastboot (power + volume up and from the mini menu 2nd option) mode and make:
Of course before was programming mode, debug mode, can unlock and unlock by fastboot command, restart, then:
c:\zuk\adb-fastboot-tool-2016\fastboot.exe flash recovery c:\zuk\power3\recovery.img
target reported max download size of 134217728 bytes
sending 'recovery' (17836 KB)...
OKAY [ 5.469s]
writing 'recovery'...
OKAY [ 0.266s]
finished. total time: 5.734s
With or without (I have tried both)
c:\zuk\power3\platform-tools\fastboot.exe boot c:\zuk\power3\2\recovery.img
downloading 'boot.img'...
OKAY [ 5.484s]
booting...
OKAY [ 0.078s]
finished. total time: 5.562s
and then if it restart by this command fastboot boot... or without it I can restart by volume up + power or by volume down+power
Any combination goes eventually to Chinese recovery with Chinese letters!
What the hell is going on and why simply fastboot boot recovery.img doesn't work as should work ?
=
My only recovery is like this Samsung
I have never had like this, NEVER:

If you got the same menu after flashing, that means that the root files are not for your phone model or android version.

And why the flash has NO error and send/ok message is on terminal during fastboot flash-ing

The mokee team ported mokee on this phone though you can find it here : https://download.mokeedev.com/nx616j.html Thanks to EspritNewGen to let me know and test it for me :highfive: He wasn't able to pass BasicIntegrity but I'm pretty sure if you install Magisk and hide the root for the play service and install MagiskProps Config to spoof your ROM fingerprint you will even be able to play PokemonGo :laugh:​

Note : Because i removed some Chinese apps like the nubia_play store for example the pets in AOD don't work (you need to install an application completely in Chinese that want call logs, contact location etc etc lol
Actually the things that don't work in the settings are :
AOD pets
Lockscreen, Launcher and Theme -> Launcher Settings
Google
Smart Service Card (i uninstalled NeoPay you can ask me if you want or mount the systemmodified.img and take it from here)
#PREPARE THE TERRAIN
First of all before loosing anything make a backup of your apps and settings using adb and also with an app like "Super Backup & Restore" for example that export your contact, sms history etc. Export all your pictures, downloads etc to your computer by usb or anything else.
You are on your own. In this tutorial i will suggest to wipe the data partition to have a clean base.
If you do something wrong simply Do the STEP 1 : Flash the ROM, TWRP and MAGISK in one paste. If there is a problem for some reason don't ask for a Discord but post here your problem -> if you can't install adb or fastboot I will help you but please search before asking.
Also, Adb does not work on all apps, some disable it in their AndroidManifest
I also say a lot of time to be in the adb directory but that's only valid for Windows and maybe Mac, on Linux its in the path except if you downloaded adb or fastboot directly as executable
Backup using ADB :
Go to settings
Click on About phone
Tap 7 times on "Build number" below the JOS version
Scroll down a little and enable "USB debugging"
Now plug it to your PC
In the notification you can see that USB debugging is turned ON
Click on "Android System · Charging this device via USB"
Click again
Select Transmit files
Now you can backup your device using adb by
Code:
adb backup -all -f backup.ab
Note : you need to have adb on your computer lol type "How to install adb" on YouTube and you will be good to go. Remember on windows you need to press Ctrl + Shift inside the directory where adb.exe and maybe some dlls are stocked to open the terminal and be able to launch adb
You phone should now suggest you to enter a password
Click backup my data and don't touch it.
Note : to see if the backup do something you can see its size on your computer Adb don't show anythings even success.
to restore the backup do
Code:
adb restore backup.ab
Now backup with USB and "Super Backup & Restore" or anything else blablabla
#LET'S THE FUN BEGIN
You need to have Fastboot on your computer, like Adb, in a directory where you opened the cmd (it is provided with the 15 seconds script on windows, on Linux(Arch) its with android-tools.)
Don't forget to run cmd as an administrator !
On windows right click on start (windows logo) and click on "Start cmd as administrator" (if its powershell its the same you just need to enter "cmd" to launch cmd in powershell) now enter "cd \Users\(username)\Desktop\Adb-Fastboot"
Extract my ROM in the fastboot directory in its own folder for example : Desktop/Adb-Fastboot/ROM
So in ROM/ directory you need to have systemmodified.img vendor.img vbmeta.img aop.mbn etc etc
#STEP 1
Flash the ROM, TWRP and MAGISK in one paste :
Long press the Power button and swipe restart
Press and hold the VOLUME- button like you want to lower the volume
Note : the VOLUME- button need to be pressed at least before the nubia logo on restart (not the shutdown animation). You don't need to press POWER because you restarted it
Now you should be in the bootloader, you can select boot to system, recovery, emerg recovery etc
Don't press on the POWER button or it will boot to something you selected
Plug your phone to your computer
In the cmd opened in the Fastboot directory select all this and paste it in the cmd (select from the first fastboot to the "s" of "stop selection here" so the cmd enter the command automatically at each new line):
Code:
fastboot oem nubia_unlock_critical NUBIA_NX616J_CRITICAL
fastboot oem nubia_unlock NUBIA_NX616J
fastboot flash recovery ROM/recoveryTWRP.img
fastboot flash boot ROM/bootMAGISK.img
fastboot flash dtbo ROM/dtbo.img
fastboot flash parameter ROM/parameter.img
fastboot flash splash ROM/splash.img
fastboot flash system ROM/systemodified.img
fastboot flash vbmeta ROM/vbmetaDISABLED.img
fastboot flash vendor ROM/vendor.img

stop selection here
Note : You need to perform these command as an elevated privilege on linux too. In fact i don't know if Fastboot require to be admin on Windows lol.
Note : You can now flash a A/B ARM64 Treble ROM if you want to learn android
#STEP 2
Make my pre-installed app working
Because i don't really know chcon and context etc my pre-installed app need some extra something to work as well as the nubia_account app because i deleted it and undo etc :
Select with the VOLUME button "reboot to recovery"
Wait for TWRP to load
Click on "Mount"
Select "System"
With the phone pluged and the cmd opened in the adb directory do :
Code:
adb shell "cd /system/system/priv-app && chcon -R u:object_r:system_file:s0 THE-BEST-FILE-EXPLORER-OF-THE-UNIVERSE TELEGRAM SMS-WITH-ENCRYPTION-BETTER-THAN-THE-NUBIA-ONE RIOT MAGISK-MANAGER LAUNCHER-OPENSOURCE KEYBOARD-OPENSOURCE FLUD-TORRENT FIREWALL FIREFOX F-DROID ../app/nubia_account"
Note : You need to perform these command as an elevated privilege on linux too. In fact i don't know if Fastboot require to be admin on Windows lol. If you launched adb as a normal user you need to first kill the adb server to relaunch it as an admin by typing "adb kill-server". It can say "WARNING: linker: Warning: couldn't read "/system/etc/ld.config.txt" for "/sbin/sh" blablabla" it doesn't matter
Now try to reboot without wiping the data to see if its working. :fingers-crossed:
If : the launcher blink and you receive some notification saying that the launcher crashed etc try to open the notification drawer and click on settings, go in app info and reset the data of Lawnchair same for Silence if it crash on start.
Else -> thanks god i made a backup.
Go back to TWRP by pressing VOLUME- (If the device is not responding when you want to shut it down press for 10-15 seconds on it to force a reboot)
in TWRP go to Wipe and swipe the button.
Try to reboot
Note : Its normal if it reboot two times
If its not working again you need to wipe everything including your pictures downloads etc (your app data was already deleted by the first wipe)
Go back to TWRP again
In the wipe option re-wipe by security the first one
Click home and re-click on wipe.
This time select "Format data", write yes and apply.
Reboot and it will work for sures.
Note : Its normal if it reboot two times
Setup you phone by disallow the localization to some nubia app etc. I included AF-Wall to block internet for the gallery, Camera etc (don't forget to Select "Block selected" by clicking the button on the right of the search button and deactivate the AF-Wall notification in the AF-Wall settings)
To receive the notification for the SMS go to settings -> App info -> Silence -> Notifications -> Importance : Urgent
#OPTIONAL - G-APPS
Install Google data-mining apps :
Note : If you install the Google apps you will have the GPS working on google maps and its all I don't appear on the Snapchat map. You need to install MicroG wich is a Open-Source alternative of the google service, so you don't have google spying on you, only Nubia :laugh: The Pico version of OpenGapps don't provide the file needed for the GPS you can download the micro version (ARM64/9.0) here[/STRIKE] -> wrong even the micro version make the GPS unavailable, I think its a OpenGapps issue I'm trying to figure it out.
I included OpenGapps Pico in /system but you can't have the GPS with it
Mount system again
Go home and click install
Click on "(Up A Level)"
Scroll down and click on system
Scroll down and click on "open_gapps-arm64-etc"
Swipe and Wait
When its done simply reboot and to the google setup
Note : Google setup don't work on the fingerprint section so skip it as well for the password or pin, just set it in the settings after.
Install Gapps MICRO wich have the GPS available
On your computer download here the ARM64/9.0/micro OpenGapps .zip file
Once finished open a terminal in the same directory where the openGapps.zipi is located (in Download I guess)
Reboot into TWRP and plug your device in your computer
Type as an elevated user
Code:
adb push OpenGapps.zip /sdcard/Download
where OpenGapps.zip is the real name of the one downloaded
In TWRP click Install and go in the Download folder
You should see OpenGapps.zip that has been copied by adb
Click, Swipe and Wait
When its done simply reboot and do the google setup
Note : Google setup don't work on the fingerprint section so skip it as well for the password or pin, just set it in the settings after.
You have now the google backup working and the Play store !
At this point your system is finally ready !
If you want to know somethings about an app or anythings that you found -> I spent 4 full day on this maybe I can help you
#OPTIONAL - MICROG
Install an Open-Source alternative of Google Service:
Note : Safetynet don't work so you can't use Snapchat or Pokemon GO for example
First you need to fake the google app signature with a Xposed module called "FakeGapps" I did not tested Tingle because I don't know how to deodex a rom as i understood it doesn't require Xposed to work, maybe Safetynet can work with it but unfortunately I didn't find any relevent tutorial .
Install "Riru - Core" from magisk
Open Magisk
Open the left panel by clicking on the Hamburger icon or swipe to the right
Click on "Download"
Wait and search for "Riru"
Scroll down to "Riru - Core", Click on the Download button and Click on install
Wait and hit reboot when its done
Install "Riru - EdXposed" from Magisk
Open Magisk
Open the left panel by clicking on the Hamburger icon or swipe to the right
Click on "Download"
Wait and search for "Riru"
Scroll down to "Riru - EdXposed", Click on the Download button and Click on install
Note : there are two version, I tested both and both work so pick wich one you want
Wait and hit reboot when its done
Install "EdXposed Installer" from Github wich is basically the Xposed app
Open Magisk
Open the left panel by clicking on the Hamburger icon or swipe to the right
Click on "Download"
Click on "Riru - "EdXposed", scroll down to "Usage" and click on "EdXposed Installer" from the step 4
You should be redirected to the Github's release page of the EdXposed Installer
Click on "Assets" and click on EdXposedInstaller_v...-release.apk"
Wait for it to download and click "OPEN" in Firefox to install it
Install "FakeGapps" from Xposed wich will fake the microG into a valid Google App
After installed it, open it and open the left panel by clicking on the Hamburger icon or swipe to the right like Magisk
Click on "Download"
Wait and search for "FakeGapps", click on it
Swipe left to go in the "VERSIONS" panel and click on "Download" the latest version
Install it
Note : if for whatever reason you can't download through Xposed in the description click on the repository link, scroll down and click on the download link, install it and go back to Xposed, Click on the hamburger icon -> Modules and tick FakeGapps
Activate FakeGapps by going in the "Modules" section of Xposed by clicking on the Hamburger icon again and tick "FakeGapps"
Reboot
Now, install MicroG
Download the latest version of NanoDroid-MicroG-NUMBER.zip (and not NanoDroid-NUMBER.zip) on your computer here : https://downloads.nanolx.org/NanoDroid/Stable/
Reboot in TWRP
Plug your devices to your computer and open a cmd in the same folder where the NanoDroid-microG-NUMBER.zip is located
Type
Code:
adb push NanoDroid-microG-NUMBER.zip /sdcard/Download
Wait and in TWRP click on "Install", it should be in the /sdcard/Download folder by default so just click on NanoDroid-microG-NUMBER.zip and swipe to install
Reboot
You should now have MicroG installed on your system and Aurora Store to replace the Play Store ! But you need some extra work to make it work lol
Open MicroG
On the Top you should see a message that say "Grant permission", click on it and allow all
Tweak some settings like you want (I have "Google device registration" Activated and UnifiedNlb Settings set on "Déjà vu" and "Nominatim")
Exit MicroG and open the Aurora Store which is the play store opensource
Note : I can't have my google account connected to it I have no idea why but you can always connect anonymously
Click on "Apps" at the bottom
Blacklist microG from updating itself by clicking on it and openning the option menu.
Refresh the installed app and you should see microG diseapear
Note : If you find something related to MicroG or google -> Blacklist
Note : to allow auto install from the Aurora Store go in Aurora Store -> settings -> Installation -> Aurora Services and grant the permission, (you need to relaunch Aurora Services to update the red icon) Go back in Installations settings and click on "Installation method", select "Aurora Services and you will be good to go !
#ADDITIONAL TWEAKS :
I deleted FileBrowser and nubia_myfile thinking there were no use for it. If you don't have them the MTP file transfer will not work !
I attached two tar.gz in this post you can open FX an create a web access to transmit those archives into your phone
Note that nubia_Myfile is maybe not needed but when we plug a OTG usb if you click on "open file" in the notification nothing will appears so I think its better to have it
Open FX and select "Web access"
Make sure you are in the same network as your computer (on the same wifi)
Click on the start button and with your computer open Firefox and go at the url displayed on your phone mine is http://192.168.1.243:2112/
Enter the password
Double click on your Download folder or where you want it doesn't matter
Drag and drop my two tar.gz file, sometime the files are not copied so you may need to drag and drop multiple times
Once the transfer is finished open FX and open one of the tar.gz, click on the folder up to either FileBrowser or nubia_myfile
Copy FileBrowser or nubia_myfile and go back to the main menu and open "System (Root)"
Go in System/priv-app and past here FileBrowser and nubia_myfile
At this point I don't know why but I could not copy the symlink in FileBrowser/lib/arm and arm64 so plug your device into your computer, select file transfer and type in a terminal
Code:
adb shell
Code:
su
Make sure to grant the permission on your phone
Code:
echo "mount your system in read write" && mount -o rw,remount /system && echo "deleting the symlink that were not copied" && rm /system/priv-app/FileBrowser/lib/arm/* /system/priv-app/FileBrowser/lib/arm64/* && echo "Creating the symlink" && ln -s /system/lib/libnubiamtp.so /system/priv-app/FileBrowser/lib/arm/libnubiamtp.so && ln -s /system/lib64/libnubiamtp.so /system/priv-app/FileBrowser/lib/arm64/libnubiamtp.so && echo "chmod 644 the symlink" && chmod 644 /system/priv-app/FileBrowser/lib/arm/libnubiamtp.so && chmod 644 /system/priv-app/FileBrowser/lib/arm64/libnubiamtp.so && echo "delete the data of the app "Media Storage" (not your data lol)" && rm -r /data/user/0/com.android.providers.media/* && echo "remount your system in read only" && mount -o ro,remount /system
Reboot
Disable the Nubia Voiceassistant button -> Settings -> More Features ->voiceassistant to not have to wait 20 years to have the shutdown menu
Disable the Colorful mode in Settings -> Display -> Screen display preferences -> Natural Mode to not have the satured black on the AOD mode
This phone is strange, i installed YouTube vanced with magisk and it keep killing the app when I listen in background it does this in call too lol, because its a system app its not shown in NeoSafe "Application power management" you need to go in Neosafe -> Detailed electricity records -> Screen or another apps but screen should be here for sure -> battery optimization -> Select all apps by clicking on "Not optimized" :
I disabled the optimization for :
Call Management
Cell Broadcasts
com.android.cellbroadcastreceiver.overlay.common
com.android.phone.overlay.common
com.android.smspush
Google Play Store
InCallUI
LocationServices
Maps
Music
Phone Services
Silence
Youtube
I am kinda dumb and wrongly edited to build.prop at the end :silly:
Open Fx File Explorer
Go to System (Root)
Click OK
Go in System
Click on the padlock
In remount "/system" Filesystem R/W tick "I understand the risk"
Click OK and open build.prop
Click on the edit button (the one with the pen)
Go all the way down and on the line "ro.min_pointer_dur=8 ro.max.fling_velocity=12000" insert a line after the 8 and remove the extra space before the ro.max.fling
Click on the option button and Save.
Now the scrolling should be a little better
To have an animation when you return on home you need to allow Lawnchair (the launcher) to have access to the recents apps
Open Magisk
Open the left panel by clicking on the Hamburger icon or swipe to the right
Click on "Download"
Wait and search for "QuickSwitch"
Click on the Download button and Click on install
Wait and hit reboot when its done
After reboot go in the app and launch the newly installed app "QuickSwitch"
Click on Lawnchair and in "Use Lawnchair as recents provider" click OK
Reboot again
After reboot open an app for example the Camera app and go back to home by swiping the middle bar and you will see a little animation like on iPhone !

Hello !
Maybe are you french ?

If so, thank you for your contribution. I wonder if I will not buy a Nubia X and your post encourages me to do it.
What return can you make me the phone, overall?
I was wondering, quite a lot of sales sites indicate that this is a global ROM. Is this really the case?
Do you think to "maintain" the ROM that you propose?
Have a good day !
Matthew
********************************
Si c'est le cas, merci pour ta contribution. Je me demande si je ne vais pas acheter un Nubia X et ton post m'incite à le faire.
Quel retour peux-tu me faire du téléphone, au global ?
je me demandais, pas mal de site de vente indiquent qu'il s'agit d'une ROM globale. Est-ce vraiment le cas ?
Penses-tu "maintenir" la ROM que tu proposes ?
Bonne journée !

Hey man lovely post and i really appreciate the work that got into this, i wonder only one thing. When i complete all the steps and got at the part where it says optional, my phone doesnt really reboot twice nor does it look like it reboots. Instead i just get a black screen, so i have to hard reset and then i can hear windows recognize the device again to press down on the volume down again, but i am kinda stuck in this step, ive done it twice the process, i think it somehow doesnt really installs the image but is busy for quite some time. You have anything that looked like this while working on this? THanks a lot hope you can help out!

wow! well written - I get the feeling that you enjoyed it very much
I have the X and I'm not so happy with it. It's basically a v3.05 version, but I bought it with a "Custom-ROM with Google-Play and German languagepack preinstalled". Generally it works and I think it's a cool piece of technology, but some things bother me: I can get no GPS-fix with GPS-Only-Apps ("speedometer"-apps), the AOD is lightly lit (no black where black should be). Did you happen to experience those things before you made your own ROM?
I tried to "downgrade" this customized ROM to the official one like posted in a nother thread, but it stops after 50% or so and says that it doesn't work :-/ Can you please advise me to make it work?
OR - do you think I can try to root it and flash TWRP onto it (as it is shown in some threads)? Or will it brick?! (I know, it's a difficult question ....) Or should I try your ROM? As I understood your way of installing, you tried NOT to wipe everything first?
Maybe you could help me a bit
Thanks alot in advance!
Tom

Hi !
Yes I'm french ZTE have released the Nubia Z20, it's the same as the Nubia X but more advanced / advanced I think it would be better to buy this one, and in September it will come out with an official global ROM, I received my nubia X 10 days before the Z20 so lol ducoup I try to sell it now after if you still want to buy the Nubia X it has dropped to 300 € so it's also a great opportunity finally if you want I can sell it to you lol.
For my overall opinion I would say that it is frankly not bad, Snapchat works in 60fps and launches in less than a second, the battery has a good day, the camera is not bad too but in low light it still remains to improve, also for example if I'm on snapchat and I switch camera, the next time I open it I'll have to press OK and change screen. there is no button "do not ask me" as on the main photo app that it changes directly screen, imprint scanners on the other hand if I record several fingers not walk or walk after the 20th test lol ducoup I have my thumb recorded after I have not tested that much, maybe I'm recording badly or whatever.
After this is the first phone to have two screen so it's normal that there are things to improve. this says it's still the class to have two screen at the beginning I make believe that I have a single screen (the one from the back) and people make fun by saying that I have a screen rotten and soon that I return it they haha ​​bugs.
Finally here I personally think you should take the Z20, just the speaker in the back to make calls shows how they push the idea to the max.
I ordered mine with a global ROM too but I think they did exactly the same as me, when I received it I had no pre-installed apps, not even the music app, the launcher was quickstep, i could update magisk etc but no more, there was just not the message that said my phone is corrupted at startup but that's it.
Maintain the ROM I do not know because I think I have done the trick if it would be a treble rom that I would have managed to carry there yes but there is already everything that works and more if I can sell it for the Z20 I could just help since my memories lol ducoup I do not know the only things I could bring this would be in the box addnal tweaks, I just see that there is a magisk module for Lawnchair to have access to the recent apps ducoup now I have a little animation when I close an app.
********************************
Salut !
Oui je suis francais ZTE ont sortie le Nubia Z20, c'est le même que le Nubia X mais plus perfectionné/avancé je pense que ce serait mieux d'acheter celui-ci, en plus en septembre il sortira avec une ROM global officiel, J'ai reçu mon nubia X 10 jours avant que le Z20 sorte lol ducoup j'essaye de le vendre maintenant :laugh: après si tu souhaite toujours acheter le Nubia X il a baisser à 300€ donc c'est aussi un belle occasion finalement si tu veux je peux te le vendre lol.
Pour mon avis global je dirais qu'il est franchement pas mal, snapchat marche en 60fps et se lance en moins d'une seconde, la batterie tient une bonne journée, la caméra est pas mal aussi mais en basse luminosité ça reste quand même à améliorer, aussi par exemple si je suis sur snapchat et que je switch de caméra, la prochaine fois que je l'ouvrirais je seras obligé d'appuyer sur OK et changer d'écran. il y a pas le boutton "ne plus me demander" comme sur l'app photo principale qui elle change direct d'écran, les scanneurs d'empreinte par contre si j'enregistre plusieurs doigts marche pas ou marche après le 20eme essais lol ducoup j'ai que mon pouce d'enregistré après j'ai pas plus testé que ça, peut-être que j'enregistre mal ou quoi.
Après c'est le premier téléphone à avoir deux écran donc c'est normale qu'il reste des choses à améliorer. ceci-dit c'est quand même la classe d'avoir deux écran au début je fait croire que j'ai un seul écran (celui de l'arrière) et les gens se moque en disant que j'ai un écran pourris puis dès que je le retourne ils bugs haha.
Enfin voila personellement je pense qu'il faudrait que tu prenne le Z20, rien que le haut parleur à l'arrière pour passer les appels montre à quel point ils pousse l'idée au max.
J'ai commandé le miens avec une ROM global aussi mais je pense qu'ils ont fait exactement pareil que moi, quand je l'ai reçu j'avais pas d'applis pré-installé, même pas l'applis musique, le launcher était quickstep, je pouvais mettre à jour magisk etc mais pas plus, il y avait juste pas le message qui dit comme quoi mon téléphone est corrompue au démarrage mais c'est tout.
Maintenir la ROM je sais pas car je pense avoir fait le tour si ce serait une rom treble que j'aurais réussi à porter là oui mais là il y a déjà tout qui marche et en plus si j'arrive à le vendre pour le Z20 je pourrais juste aider depuis mes souvenirs lol ducoup je sais pas les seules choses que je pourrais apporter ce serais dans la case additionnal tweaks, je viens de voir que il y a un module magisk pour que Lawnchair ai accès au applis récentes ducoup maintenant j'ai une petite animation quand je ferme une applis.

Hi ! Thanks a lot By optionnal do you mean at the Gapps part ? Does OpenGapps say an error in TWRP ? If you reset your phone after flashing OpenGapps it will not uninstall them, because you erase only the /data partition (and Dalvik/cache) so maybe you mean you re-flashed everything, in this case i don't know why it is stuck after flashing the Gapps can you try to do the first wipe (Data, Cache and Dalvik) after flashed OpenGapps ?
when you say

Click to collapse
your phone shouldn't reboot two times because you don't wipe anything in this step. To reboot you just swipe "reboot" after flashing the OpenGapps zip file ? Windows recognize the devices at boot and in TWRP, when you reboot your devices does windows make sound like you un-plugged your device and plugged in again ? If yes check that you can't access the file on your devices (the phone launch an autorun for windows where in TWRP you can access the file in the devices) and try to see if its in fastboot mode by typing in admin or with sudo
Code:
fastboot devices[CODE]
If nothing changed after that let me know, i will try do follow my post step by step maybe i forgot something ;)

Hi :D ! Yeah I have learned more than that I could have ever imagined !
I myself also have bought it with a "Global" ROM but it is basically what I did, there is just the pre-installed app removed and the playstore added and vbmeta disabled to allow changing the boot partition (magisk update for example), I just tried the GPS with "GPS test" and I also can't have any signals I have to turn the airplane mode to have one satellite but I couldn't do it again (I will try outside after this post).
For the AOD I had exactly the same issue you need to switch to sRGB mode in Settings -> Display -> Screen display preferences -> Natural mode.
[QUOTE="hellraisertg72, post: 80112550, member: 6973608"]but it stops after 50% or so and says that it doesn't work :-/[/QUOTE]
50% ? do you mean the JOS things at the first boot ? Or when you go in the Recovery and update it with an OTG usb ? In the last case you can't downgrade with this method you need to flash with fastboot like I did for this ROM and reset everything (I didn't tested to downgrade but i read that you must reset it to downgrade).
you can't brick it if you use the .exe provided by nubia but because its a "global" ROM (so not official) it will probably say "this devices is corrupt" in this case you can flash vbmeta.img to bypass it but in any case you can't brick it at the point of not having fastboot so if it don't work for any reason you can always flash my ROM by fastboot and try to keep your /data partition (I didn't tested to have the settings from another ROM and then switch to my ROM but as the Android system is built it should work without any problem. Maybe you will notice some "blabla is not responding" or "blabla has crashed" but in this case you just need to reset the problematic app). Mine was already rooted, I got kicked off the battlebus for cheat in Fortnite because of that :laugh: you can download Magisk Manager and see if its already rooted

Hi Roman!
You are my/THE hero
1) the trick with the color-mode changed it to a real AOD - thanks!!!
2) GPS is a pain in the a... in the X - I read that you already bought the new Z20 (from where, btw? I got my X from cect-shop.com), did you receive it yet? Hopefully at least GPS is working better!!!
3) yes, you were right (of course ) - I tried the recovery-update-installation. You meant that I just have to fully reset the X first then go into recovery und "downgrade" with the NX616J-update.zip - file?
4) I'd also like to sell my X and buy the Global-Version of the Z20 - that thing is really great (at least I think so regarding the first Indian and Chinese handon-tests )

Hahaha I am honoured :angel:
When I found it I was like "Ohhhhh sh" lol, I tested the GPS outdoor and I get a signal 5 secondes after i turned it on on "GPS test" but the app said that I get a very poor signal so i waited for ~1 minute but thats all I could get now if I test indoor only Google maps can see my position, "GPS test" don't. I tried this but i can't make matlab working i will try on Windows so i will not get libblabla.so.6 error.
I did not buy the Z20 but i really want to, I posted my X on sale but nobody want it except for 200€ lol.
I never downgraded this phone I just read somewhere that Nubia said that we must factory reset the phone but i'm pretty sure you need to flash the rom with TWRP like the OPTIONNAL - GAPPS section of my post or with fastboot but you first need to convert the system.new.dat.br and the vendor.new.dat.br into a raw img file before by decompressing them with brotli and convert the .dat to a raw img file by
Code:
sdat2img systemorvendor.new.dat systemorvendor.transfer.list systemorvendor.img
and flash it with fastboot exactly like my ROM.
They even put a back speaker to make call on the other display ! The triple camera set with the two flash make me regret my X lol even the back screen show a preview of the camera when you take a picture from the main screen the only bad things is the screen ratio, on the X the screen is more border-less than the Z20 but it doesn't matter haha if you want to buy the Z20 I can suggest you "V-Phone Store" on Aliexpress wich is the same store that i used for the X thay have it here

Hi Roman!
You are my/THE hero
1) the trick with the color-mode changed it to a real AOD - thanks!!!
2) GPS is a pain in the a... in the X - I read that you already bought the new Z20 (from where, btw? I got my X from cect-shop.com), did you receive it yet? Hopefully at least GPS is working better!!!
3) yes, you were right (of course ) - I tried the recovery-update-installation. You meant that I just have to fully reset the X first then go into recovery und "downgrade" with the NX616J-update.zip - file?
4) I'd also like to sell my X and buy the Global-Version of the Z20 - that thing is really great (at least I think so regarding the first Indian and Chinese handon-tests )

Oh god i found the issue with the GPS you need to remove all the google stuff and install microG
EDIT : The Pico version of OpenGapps don't provide the apk needed for the GPS i installed OpenGapps Micro and it work well, I just can't get pokemon Go working even if i have BasicIntegrity and Cts true I wonder why

Hi Roman!
Finally I tried the flashing and it worked - thank you very much! I did not even loose any private data. I just flashed microgapps like you proposed and I had to verify the Google-account again - but it worked.
The GPS-Problem persists, alas, at least in a smaller amount. With GPS-Test (play.google.com/store/apps/details?id=com.android.gpstest) it works perfectly. After 2 secs I have a fix wirh "hundreds" of satelites But with other GPS-Apps like "Speedometer GPS PRO" (play.google.com/store/apps/details?id=luo.speedometergpspro) it didn't work again
Did I miss something? (I didn't do the brotli and packing thing, by the way... just flashed the microgapps)...
And another thing: I like your(?) dog, but I'd like to build my own splash.img - can you help me please?
Many thanks in advance!
Tom

I'm happy to hear that !
I tried to re-flash and re-reset my phone to make sure it was the openGapps Pico that caused problem by using the Micro one but i couldn't get any GPS signal, only google maps worked. So I plugged my phone to my computer and watched the logcat, I just saw that google maps created some sort of request to GnssLocationProvider and TencentLocationProviderProxy and then saw that when I launched SatStat there were some warning about missing permission (in fact the Phone and the Storage permission was refused by default for this app). So I tried to enable them and relaunch it to see and it worked ! so now all my app that need GPS work. I tried to re-refuse the permission and it still work lol I even played Pokemon Go for 2 minutes before get the unsupported devices message (I'm sure it see magisk installed). I tried your app and I could not make it work, even on a genymotion's Pixel 3 virtual machine where gps test report my accuracy and position (I can only modify the latitude, longitude and accuracy). I opened the logcat and i saw this :
Code:
AppOps : do not show dialog !!! application luo.speedometergpspro targetSdkversion below M , and op 1 is dangerous permission .
It look like the developer don't want to fully port his app to Pie, but instead keep it to Marshmallow. I never touched or created an Android app so I may be wrong
EDIT : No i'm just wrong lol the targetsdk of the app is 28 so it should be good here is my post the next day about the gps in general
Yeah i already converted the stock rom to a Raw image so you don't need to decompress and convert the sparse image etc
What !? you want to remove my beautiful dog ??? lol I forgot I modified that, I changed it in /system/media/theme/bootup. You can modify picture_1.nubia, picture_2.nubia etc don't worry about the .nubia extension they are just png. If you want to modify them open Fx file explorer and click on "System (Root)" and go in system/media/theme/bootup from here you can copy thoses file on your computer and make the changes you want I just worry about the right, ownership and security context (the chcon command that you did with adb to make my pre-installed app working is for this) of the file when you modify them you may need to re-chmod 644, re-chown root:root and chcon ubject_r:system_file:s0 the file after copied and renamed them in /system/media/theme/bootup.
In step it look like this :
Open FX File explorer, do the first time setup etc
Click on "System (Root)"
Go in system/media/theme/bootup
you can open them if you want by clicking on and selecting Image Viewer (You can see how I was aware of odexing an app in fullbg.nubia lol)
Select picture_1.nubia, picture_2.nubia etc and copy them in your download folder for example
Copy the .nubia/.txt to your computer
I don't have windows to test but on Linux you need to change the owner (root) to your in order to modify the file by using
Code:
chown $USER picture_1.nubia/picture_1.txt
Note : When saving the picture make sure to have the same name and export the picture in png, I didn't tested if it support anything else that would be cool to display a GIF
Copy them on your phone and select and copy them with FX
Before pasting the .nubia make sure to click on the padlock and tick "I understand the risk." and OK to be able to write in.
Now paste the picture and select "Merge/Overwrite" to replace the original or delete the original and rename the new with the good name
To restore the chmod things etc first see if its necessary, select the .nubia that you overwrited, click on the option button at the top-right and click on the info button (the first one) it should be like this :
Code:
Security Context -> u:object_r:system_file:s0
Owner -> root
Group -> root
Octal : 0644
If its not like this you need to
Download Termux on the play store and open it
Wait for it to install and type "su" and grant the permission on the magisk popup to become root
Code:
mount -o rw,remount /system
to be able to write in the /system partition (I say partition but its actually a partition in a directory named system)
Code:
cd /system/media/theme
to move to the theme directory
Code:
chmod -R 644 bootup/
To set the 0644 Octal type in the entire bootup directory (to avoid doing this for every .nubia/.txt file)
Code:
chown -R root:root bootup/
To set the root owner and group
Code:
chcon -R u:object_r:system_file:s0 bootup/
To change the Security Context
Code:
chmod 755 bootup
To restore the original 755 octal of the bootup directory (In fact you could just avoid the -R option in the previous command and chmod/chcon/chown bootup/* where "*" is to select all the file so in this case all the file in bootup/ without changing the bootup directory)
You have now removed my cool dog. If you want to change the sound as well its in /system/media/audio/ui and its called bootup.wav it also have the 0644, root:root and the same security context of the pictures.
Its more easy to change it than the picture because you just need to convert any song you want to wav by using a online converter for example and put it in /system/media/audio/ui, change the owner, security and 644 and of course you need to rename it to bootup.wav (make sure if you use FX to replace it to select "System (Root)" instead of "System" and click on the padlock to be able to modify the /system partition)
I never touched the splash.img I think it only contain the Nubia logo displayed at boot because the shutdown animation is in /system/media/theme/shutdown
EDIT : the splash.img don't need to contain anything because when I tried LineageOS I didn't get the nubia logo but the Lineage one

Hi !
Thx for your message

Thank you OP for such a wonderful work. I bought it for $625 from geekbuying and now price for $400. Biggest disadvantage is not having proper global rom..

Hi Roman!
Finally, (at this point) GPS is working on GPS-Only-Apps, google is working and it looks fine... BUT (oh no, again!) - now I can't get a file-transfer-connection either to linux or windows (10).

Do you have an idea, why?! (maybe it's the "-" and the "_" in the name and not in the mount-name?)
Thanks,

The GPS drive me nuts
Without Gapps Pico or Micro it work perfectly etc I even get speedometer working but not the latest version only the 3.7.21 or lower without "googlemaps" in parenthesis work
The latest version of speedometer log this in Logcat
Code:
GooglePlayServicesUtil: Google Play Store is missing.
so its not working of course.
When I flash OpenGapps the only position I got is the one from the cell tower in Magic earth or nothing at all for GPS test and Satstat. Only Google maps work normal. But the most disturbing things is that I need to wait one day and open the permission of Satstat to grant the Storage and Call permission to "unlock" the gps for SatStat, GPS test or Magic earth. In fact Magic earth show my position based on the last fix that SatStat did, if I wait some time it will show me again the cell tower lol. I think if I launch Snapchat, Pokemon Go or anything else that use the google api the gps will not work.
I've hidden the root for Snapchat, pokemon Go and Fortnite and i also renamed the com.magisk into com.fsdijuhg in the magisk settings and I changed my build fingerprint using "Magisk Hide Props Config" to pass cts. Fortnite work well I can jump off the battlebus without being kicked out for cheating but Pokemon Go and Snapchat don't find any GPS signal so it shouldn't be a root or safetynet issue. Or Fortnite is broken. EDIT : I can play it without google play services the game mode help a lot I must say
If someone have an idea or have already got this problem please help me
I also tweaked the gps.conf as well as the izat.conf flp etc but nothing worked so far

I just cheched and its because I removed the filebrowser app and nubia_myfile I though I only removed the nubia_Myfile. My bad. I attached two tar.gz you can open FX an create a web access to transmit those archives into your phone
Note that nubia_Myfile is maybe not needed but when we plug a OTG usb the notification can't open it so I think its better to have it
In step :
Open FX and select "Web access"
Make sure you are in the same network as your computer (on the same wifi)
Click on the start button and with your computer open Firefox and go at the url displayed on your phone mine is http://192.168.1.243:2112/
Enter the password
Double click on your Download folder or where you want it doesn't matter
Drag and drop my two tar.gz file, sometime the files are not copied so you may need to drag and drop multiple times
Once the transfer is finished open FX and open one of the tar.gz, click on the folder up to either FileBrowser or nubia_myfile
Copy FileBrowser or nubia_myfile and go back to the main menu and open "System (Root)"
Go in System/priv-app and past here FileBrowser and nubia_myfile
At this point I don't know why but I could not copy the symlink in FileBrowser/lib/arm and arm64 so plug your device into your computer, select file transfer and type in a terminal
Code:
adb shell
Code:
su
Make sure to grant the permission on your phone
Code:
echo "mount your system in read write" && mount -o rw,remount /system && echo "deleting the symlink that were not copied" && rm /system/priv-app/FileBrowser/lib/arm/* /system/priv-app/FileBrowser/lib/arm64/* && echo "Creating the symlink" && ln -s /system/lib/libnubiamtp.so /system/priv-app/FileBrowser/lib/arm/libnubiamtp.so && ln -s /system/lib64/libnubiamtp.so /system/priv-app/FileBrowser/lib/arm64/libnubiamtp.so && echo "chmod 644 the symlink" && chmod 644 /system/priv-app/FileBrowser/lib/arm/libnubiamtp.so && chmod 644 /system/priv-app/FileBrowser/lib/arm64/libnubiamtp.so && echo "delete the data of the app "Media Storage" (not your data lol)" && rm -r /data/user/0/com.android.providers.media/* && echo "remount your system in read only" && mount -o ro,remount /system
Reboot
You should be good now I will update my main post about it
And also thanks for your logs ! That's one less thing I had to do

It is now at 300€ on Aliexpress :laugh: ! With the shipping i get mine at 500€, I'm disapointed. Yeah imagine the number of people that would have bought it... At first I though someone would make some "hacky" stuff for it like changing the way the dual screen work or maybe port a custom rom for it (I tried but I'm not good enough lol) but no, they released a update to fix certain bugs and after 1 day there were 107 comments on their forum where in xda 0

YESSSS! You are the best - thank you - it worked perfectly. Hopefully my having worked GPS is still working after the reboot... Will try it soon outdoors
p.s.: what about the new v3.11 - update (my X is claiming there is a new one out there )? I assume I cannot install it easily per TWRP over your/the V3.05 without at least losing the X to a brick So - will you be able to make a new version of your ROM based on the V3.11?
Thanks alot!
"So long and thanks for the fish" - bye!

You're welcome ! I still have no clue why OpenGapps or google service disable the GPS by the way
I saw their post here but it only have "System stability" in the changelog I will try tomorrow to download it and install it so hopefully I can extract the new .img with TWRP and remove the chinease app and install FX Silence etc to make a new build, maybe the GPS will work who know
And by the way you can't install the update if you try lol it will complain about the root even if you uninstall magisk haha
EDIT : I found how to cheat the root by the way you need to flash the partition.img wich is in fact a text files saying "empty"
and when you unlock the bootloader it will change into this :
on the last line the last number is how many time I unlocked it (01) if you change it to FF it will become 255 lol its a strange way to flex but you can do it :laugh: I think the number 1 and 0 from "BOOT IS ROOT", "DEVICE IS ROOT" and maybe "DEVICE IS ROOT" came when you flash the boot partition, the system and when you unlock the bootloader but I'm not 100% for the last one. Only "FASTBOOT UNLOCK COUNT" number is written in parameter.img
I can't update it to 3.11 even with only the recovery changed to TWRP and without, I removed the SHA1 check of the system partition because somehow the stock one get changed but I'm stuck at "E1001: Failed to update system image."
If you want to download the 3.11 OTA update I uploaded here : https://mega.nz/#!PO5FXQ7A!mHsX4lSz4FkJGa3ZBhHIWljOlKUaITzGsz21bdg9Mhs

Hi Roman!
Sorry for the long answering delay... been very busy lately
But now I will try some things again - therefore I have one question: the provided OTAv311.zip is just for trying if it will work on my X or will it work when I flash it per TWRP!? I didn't catch that of your explanation, sorry :silly:
BTW: my GPS is still working (at least here: GPS Speedometer and Odometer (Early Access), ver 12.5) - but I have still no clue, why it is (maybe some developers are paying more attention to google's API) I'm just happy with it (unfortunately it is PIE-related, I assume - some other android-pie users on other smartphones are complaining on this "feature"....)

Hi I uploaded the update for anyone who simply want it so there is no need to download with the update application and extract from the ota folder this .zip, concerning the GPS I no longer have this phone and I never found why it never worked with the google api. It work with MicroG but not with google I'm not sure its Pie related if you remove google from a samsung and flash openGapps it will work for sure, I'm pretty sure its because of a config file in the /vendor I don't remember which exactly but one had tencent location service instead of Google gms I changed it but nothing happend maybe if you remove tencent Location Service and watch the logcat you can retrace the origin of the problem though.
Mokee released a ROM for the X but you don't have BasicIntegrity (maybe with magisk you can tweak it) if I remember correctly, the guy from the channel EspritNewGen tried it but I don't remember if the GPS worked with google api I posted the link on the main post if you want to try it

Root samsung sm-j730, j7y17ltexx, j730FXXU8CUE8

Hello,
I am trying to Root for the samsung smj730 ITV (technical specifications in the picture), j7y17ltexx with version j730FXXU8CUE8 android 9.
I have installed Magisk-v19.3, no-verity-opt-encrypt-6.0 and RMM-State_Bypass_Mesa_v2. as in the video "
".
Once the procedure is finished, I checked the result using "root-checker-6-5-0" and disabled the samsung security services with "disable application" ..
I install "shortcut-master-lite-1-2-7" and grant root rights via magisk manager version 19.3.
Shortcut lite does not load the services.
I do not encounter this problem with the phone sm-j730f, j7y17ltexx with version J730FXXU2ARG1 android 7, I can root through the file CF-Auto-Root-j7y17lte-j7y17ltexx-smj730f.tar, I install shortcut-master-lite-1- 2-7, granting root and shortcut rights works fine.
Is there any way to switch from Android J730FXXU8CUE8 to Android J730FXXU2ARG1?
How can I root j7y17ltexx with j730FXXU8CUE8 android 9 version so that I can use shortcut lite?

Good morning,
I'll explain the files and applications used to root the sm-j730 android 9 pie.
After unlocking the "developer mode" from the phone on, I restarted the sm-j730f in "download" mode, through Odin I installed the following file in "AP" to access "TeamWin" to root, below the file used:
- TWRP-3.2.3-TwrpBuilder-j7y17lte-2018-09-13_15-35
in TeamWin I ran the video link in the initial post, where it explained to reset the cache both in Wipe and advanced wipe. I installed the no-verity-opt-encrypt file to modify the device OEM and RMM-State_Bypass to disable Samsung OEM Unlock jail and OEM Unlock option, below are the files used:
- no-verity-opt-encrypt-6.1
- RMM-State_Bypass_Mesa_v2
To root I installed Magisk-v19.3, and restarted the device by unchecking Promt install TWRP and Install System App and pressing do not install. Below is the file used:
- Magisk-v19.3
After restarting the phone, I rerun the steps to get developer permissions. At this point I disabled the samsung protection via disable application, I installed root-checker to check that the root process was successful. Through magisk manager_v9.0 I gave root rights to the two newly installed applications and at this point I was ready to use shortcut lite. The apps used are as follows:
- disable applicarion
- root-checker-6-5-0
Through magisk manager_v9.0 I gave the root id rights also to the shortcut lite application, by executing the answer I received the answer that I enabled the root rights, I made a verification test with the code 0011 and executed through the command "favorite" root 0, the application writes me "root required" and does not execute the command. Below is the app used:
- shortcutmaster.lite_1.2.7
I did a further check on the call by typing "* # 2263 #" and the phone replies with the standard message from phone without root permissions.

[KERNEL] Bandido - G780/G781 (overclock/usb-charging/undervolt/better scaling)

The Linux kernel is the core component of the Android operating system. It is a software program that manages the system's hardware resources, such as the processor, memory, and input/output devices, and provides a foundation upon which other software programs can run. The Android System runs on top of the Kernel the same way applications run on top of the Android System. Below the Kernel, only the hardware itself.
It should be installed via Recovery (TWRP) or FKM over Stock or GSI ROMS (Android 12 or 13). It doesn't need any tweaking with any app, just install it and use it.
BUT you can use any kernel tweaking app to change settings.
It has UNIQUE features like:
- no CRC checking on mmc reads, for performance
- disabled some cpu throttling and "touch boosters" (more speed and less battery usage)
- Bandido governor, a battery-friendly governor
- BandSaver governor, a SUPER battery-friendly governor
- removed A LOT of unuseful kernel code
- "Fair scheduler" tweaks
- a lot of power saved when the screen is off
- USB fast charging
- latest GCC (compiler), 14
And some common features:
- add 200mhz GPU clock to save power
- GPU overclocked to 900mhz, stable
- GPU undervolt to save battery and keep it cool
- added every TCP congestion control algorithms
- added conservative and ondemand CPU governors
- KCAL support
Overall your phone will be snappier, and at the same time less battery hungry
Make a backup of your BOOT partition with TWRP just in case you want to go back to a slower experience lol

wow, I will definitely test!

sweet... congrats fella
will give it a test now.

Great thank you i think my battery life is so good with this one

Thank you, works without issues on the Project X ROM on the G781B.
EDIT: I'd just recommend setting Westwood as the default TCP congestion algorithm since it is the fastest. By setting it to default, users don't need to install a third-party app to set it themselves

Does it work on exynos version?

Any sources about westwood (from 2001) being faster than BBR (2017) ??
Google uses BBR and as most ppl uses google services, this match would be welcome

Westwood is the more mature algorithm compared to BBR, and is more stable and subject to less packet loss. I might need to do some testing. Is BBR the default setting for the kernel?

The table you just posted says everything.. BBR even with 3% of loss can reach 132 Mb/s.. do you want 0.97 Mb/s instead dude ???
Yes, BBR is the default for me.

@fbs something I've noticed in all the FE (5G) kernels I've tested, the app AFWall+ gets messed up when trying apply iptable rules. I asked Sam if a kernel could affect it and he said yes it could but it shouldn't or something like that.
I've just switched from stock to Bandido again and AFWall+ has gone from working perfectly to screwed up again too...any ideas what might be the cause ?

I haven't changed anything in the network code.. it should be just like stock... I'll take a look at it

Will I need to flash the kernel again after every monthly security update?

Maybe, but you can check which kernel you're using on About Phone -> Software Information

is this kernel only working for rooted device?

@fbs Great work with the kernel, keep it up
By the way, I just wanted to let you know about a bug with pausing/resuming multimedia with the earphones. It freezes the device and makes it to restart. I reproduced the steps with stock boot.img and everything's fine.
My variant is G780G, don't know if it's the same for G781B

Nope. It also works on non-rooted devices.

Newer version is up.. I think I managed to get good battery savings
And now the same file works for both variants (4g or 5g)
