The FCT's of coolpad - CoolPad Note 3 Guides, News, & Discussion

Hello every on !
Today I am here to share details of my research on the Coolpad Note 3 stock ROM method to implement fingerprint.
This is mainly targeted on fingerprint.
The thing coolpad has enabled new is "fct". I call it new because i haven't see any such in other device.
On close examining the factory_init.rc of the boot image, i have found a service to activate a file with name "fctd", which has been using to activate the libraries "fct_*" of the lib{,64} of the system mount point.
So, how actually is this factory_init.rc called, The coolpad note 3's ramdisk has a file with name multi_init in the sbin directory, which is again activated by "init". This init is obviously loaded by the bootloader initially.
So the fctd plays a major role in the fingerprint. Based on these , I have enabled fingerprint on custom ROMs of the coolpad. :angel:
The software team of coolpad wanted things to be seperated, so that if there exists any problem with any segment, they can fix them easily, that is the main reason they have implemented this fct's.
Any corrections to this are accepted
Hope fellow developers would gain some knowledge from what i shared, and also correct me if iam wrong

Good findings.
Keep up ?

1. If you are rooted then simply replace the /system/etc/hosts file with one included in stock rom.
2. If not rooted then you will need flashable zip file for that. I'll create one tomorrow and will upload here.

Thanks a lot!
It really does work but some just get through like those on the Leo Master app, is there any way that you could add them as well so that they're blocked as well?
I would really appreciate that a lot... It's really annoying but I can understand if you don't want to do it as well, in that case could you please guide me on how to do it?
P.S I'm a noob, but I'll try my best to learn.

[ROM] [MM] Chinese CM 13 (Unofficial) Redmi Note 3 (SD)

I created this thread because this ROM is been discussed in lot of others threads. So let's give it a separate dedicated place .
This ROM is for for advance users only. If you don't know what you're doing, don't even think of trying. Proceed at your own risk.
Problem you may face:
Will relock your bootloader.
You may not be able to restore your previous backup.
It is working great for some people and for some people it's a nightmare.
You tell me.
Why you should install it, there are 2 reasons.
You miss Finger Print Sensor
You miss Finger Print Sensor a lot.
Fingerprint unlock performance is amazingly faster than offical MIUI. And in case you don't miss Fingerprint sensor , I don't see any point of flashing this ROM. Instead go here [CYNOGEN MOD 13 ]and install my favorite ROM from one of my Fav developer @Santosh
Working:
RIL
Audio
Camera
Infrared
Finger Print Sensor
And everything except things mentioned in "not working"
Not working:
GPS
May be some other things.
Here's the offical thread. It's in Chinese language so you may need to use Google translator unless you know Chinese.

Can you explain step by step, if you don't mind.
safest way would be to dl fastboot ROM from miui, flash it via miflash. then simply unlock BL again using MI unlock, flash recovery as you did before and you re good to go. fastboot rom will revert everything on ur phone like it was when u bought it. rooting/unlocking you'll need to do again, but hes everything will be working as it should.

Simply speaking ,it is a bootloader replacement(or a modified bootloader) by which u can install multiple ROMs and recoveries at same time.U can run a miui ROM,aosp rom,Ubuntu Linux and u don't need any patched kernel or a multirom recovery or multirom supported rom .And no need of confirmation if a ROM can be booted as secondary or primary ROM as there is no terms like that.
@deeps7515 @preetnoobie
Bootloader is the first thing that get loaded in the memory after the device starts. Once the bootloader gets loaded in the memory, it handles OS initialization, and the OS initiates only after that point.
The goal of this project is to generify the process of bootloading, so that any ROM or any kernel can be loaded into memory without any kind of modification at all, through some universal architechture. The technical details are vast enough and quite frankly, even I don't understand many of that.
TL;DR
It will make multibooting buttery smooth in our devices.
if i am not wrong .. now we can also install complete armhf based linux distros??

Well sadly, sailfish still requires some work to be done because of the hardcoded system.mount, and I directly jump into it after I publish the first beta. Right now, I'm experiencing some weird bug that apparantly noone has faced before, and that's why the build is taking longer than expected.
Stay tuned.

[HowTO] Treble for S9

Hello everyone,
After seeing the news that Treble images were properly working on the S9, I decided to give it a go and see for myself how good/bad was it working.
The from my findings, the only thing that is NOT working is the auto-brightness.
Here are the installation steps :
Make sure you got TWRP installed properly, with DM-Verity and Encryption disabled.
Download this : https://www.androidfilehost.com/?fid=817906626617958348
Place it in the root of your device, then navigate to TWRP, click install, click install Image, select the transfered system.img, and select system image.
Make sure to full wipe after that, and reboot, and you are good to go.
This is awesome. As soon as I'm able to get my hands on an Exynos variant S9, I'm buying one for Treble support alone.
Auto-brightness doesn't work because the framework doesn't define any brightness levels for each lux level. You can make an overlay to fix that or modify the framework at source.

It's also framework related so very much unlikely to happen.

Porting the frameworks has recently happened for Huawei and Sony. Unless Samsung are deliberately obfuscating things, it should be possible to do the same for the Exynos versions of the S9 and S9+.
Can someone post screenshots
Im so excited .. this is one of the biggest reasons why I will switch to s9+

I have one more question, when I flashed aosp ROM it worked fine but with the brightness glitch, however when I flashed lineage os it just bootlooped so any suggestions ?

26th builds of 8.1 are okay for brightness but fingerprint is broken for some and causes touch to stop but reboot, unlock then a few lock/unlock cycles it's good temp fix til next reboot

{ROM} GSI Lineage OS For Our Redmi 6!

Hi There Everyone!​First a brief: I've been a longtime XDA user, but never found the need to create an account. Now, I bought a Redmi 6 and I'm really disappointed by the development:crying:, so I thought i'd chip in a bit I don't have permission yet, so I posted this here.
As you know, till now there are NO Custom ROM's available. This is really sad, and I can't live with MIUI. So I decided to give GSI (Generic System Image) ROM's a try.
And guess what? They work! I tried installing Lineage OS 15.1 on our cereus. The rom is really fast and smooth. Here's what I found:
Working:
Wifi
Bt
Camera
Vibration
Sound
Finger Print
Bugs:
SIM detected, but no range found. RIP calls/sms/data. Looks like a problem with the raido's.
Headphones don't work
I couldn't test hotspot and gps.
Even though there is a bad bug, it still works surprisingly on this MediaTek SoC with no drivers / kernels. All we need is a little paching and we should be good to go!
Give it a try. Ill post guide on how to do this later. For now, i'm using miui cuz i wanna make phone calls

I know, and I've read through all that. They are all buried inside TWRP threads, and not everyone knows about GSI. I made this so people know, and I'm also going to make an other thread with instructions on how to flash a GSI rom for our Redmi 6 soon (It's a little tricky getting TWRp to work and all...)

It works! Sorry, I forgot to mention that - added it now :good: Btw, even though it works, it isn't as accurate and as fast as MIUI.

I meant to say good job about putting this all together. Nice.
I just randomly remembered when i was trying this ROM some time ago. Headphones doesn't work.
(Adding this to post would be ideal)
Edit: It could also be the Pixel Experience ROM. But i don't remember.

Thanks! I tried LOS again, and I can confirm that headphones don't work. Added that to the post:good: Btw, do you know any GSI ROMs for Cereus that can actually make calls and work well?

All i tried was LOS and Pixel Eperience. Both are same, except PE has Android 9.0. I tried treble RR, it had really cool logo while booting, and i was really excited for RR because i never tried it. But i never made it to boot. Boot logo is looping infinitely and i tried fresh installing (With MiFlash clear) about 10 times.
Edit: Maybe if you would want to, you can give it a try https://forum.xda-developers.com/pr...0-resurrection-remix-v7-0-arm64-32-b-t3891636
Edit: I didn't understand most of it, but i could start adb logcat while booting. From all i could understand, all apps were dying and restarting all over.

Omni rom, android 9, works pretty good, no major bugs.
Installation instructions on screenshot in attachments.

Yep, only USSD is broken by default. See 11) on screenshot.
Calls/sms works out of box.
Don't know about volte since my carrier doesn't support it.

Seems that mtk ussd fix breaks something on other phones. So, this is flag to enable it.

Ahh, you mean how to append?
Open /system/build.prop file with text editor that has root access, add line to end, save file, reboot.
Or you can do this via adb/terminal emulator:
1) su
2) echo persist.sys.radio.ussd.fix=true >> /system/build.prop

Since you said ussd is broken by default i thought that that wouldn't fix it.

By default — right after installing, without adding this line.

Oh my bad. By the way I'm going to install this rom and I'll see if that line fixes ussd. Then we'll have a probably fully functional rom for the redmi 6. ****ing finally. It's about time.

It doesn't work for me. Same as every single other GSI rom.
