[guide][root] Tweaks Redmi 4x stock ROM

[tweakradje]

No. 1x1 cpu. Do you have Redmi 4X? (santoni)

Check with adb shell, then su:

- getprop ro.board.platform (msm8937)
- cat /sys/devices/soc0/soc_id (313)

If not then changes will not apply.

of course i do have redmi 4x santoni. iam running miui 7.7.20 nougat 7.1.2 the first .sh work, but RRV3 version makes no changes on cpu config.. i checked it usimg cpuz

 

[tweakradje]

Ok. Then I don't know what is wrong then.
Try this:
adb shell grep "###" /etc/init.qcom.post_boot.sh

It should come up with many ### lines that I put in there. If not you have not changed the proper file.

 

[NTLinhHaHa]

@OP: I edited the file directly, using FX File Explorer, and the script worked for me. I didn't replace files.

 

[nightvury]

looks like your RRV3 version doestn work on MIUI 7.7.20 Nougat.. So i used the 1st version of your .sh file and cpu config changed to 1x1

really nice work man!

Thanks a lot for clean guide here.. I know SD435 in santoni Supports WiFi 5Ghz/ac. Since stock MIUI doesn't support it, is it possible for some tweak to enable WiFi ac @tweakradje?

 

[tweakradje]

In hotspot mode you can choose 5 Ghz. So chip supports it. I have tried a couple of hours to get ac working for normal wifi but no luck so far. Maybe later.
If you do logcat|grep wpa you see ac is supported if you toggle wifi.

If I look into the source code it needs to be defined at compilation time?
See source code here.

So we need another msm wlan.ko module? Redmi Note 4X supports 11ac. I try that wlan.ko
EDIT: wlan.ko from Note 4X don't load.

typedef enum
{
    eHDD_DOT11_MODE_AUTO = 0, //covers all things we support
    eHDD_DOT11_MODE_abg,      //11a/b/g only, no HT, no proprietary
    eHDD_DOT11_MODE_11b,
    eHDD_DOT11_MODE_11g,
    eHDD_DOT11_MODE_11n,
    eHDD_DOT11_MODE_11g_ONLY,
    eHDD_DOT11_MODE_11n_ONLY,
    eHDD_DOT11_MODE_11b_ONLY,
#ifdef WLAN_FEATURE_11AC
    eHDD_DOT11_MODE_11ac_ONLY,
    eHDD_DOT11_MODE_11ac,
#endif
}eHddDot11Mode;

Try Wifi hotspot. There is 5 Ghz. I have looked into msm wifi driver. It only needs a flag when compiling.

Thanks a lot for reply. Since I wasn't tagged in your first reply I didn't see that. Maybe this 5Ghz WiFi you can include in your first post Santoni facts.. Hope to see 4x connecting to our 5Ghz AP....

Has anyone tried the tweaks in MIUI 9?

 

[JoseRT5]

I dont understand very well the tutorial for decript data partition.

When i do the second step "Backup /data to "internal sd" (or to "ext sd card") with TWRP", do i have to put the phone on fastboot mode for do the 3rd step "On PC: adb pull /data/media/0"? Thank you very much

 

[tweakradje]

@JoseRT5 all is done from recovery! Where did you read fastboot in instruction?

ps: if you don't care about your data then no need for backup/restore steps of course

 

[boom1982]

good tweaks

My pc said "device not found". I already have drivers installed

Solved, I formatted /Data from TWRP and installed RR again

@tweakradje
Hi)
Many phones have already made a stereo sound (when the multimedia and spoken speakers sound together)
can you do also for redmi 4x?

LED notification not showing

Anyone running RR with my V2 script having battery drain issues? I have since yesterday.

I am now running new script to test battery drain. The change is to disable all these
low power modes again. Lets see tomorrow.

Oh and if you see the notification led blinking purple after reboot? The V3 script switches it
off again after 3 sec.

After using your v3 Script on RR N-final the led notification stopped showing at all. It shows Purple during boot as you said for 3sec. But later on the LEDs are not showing at all

Update: used this zip to make it work it again

Will update you about night drainage & battery backup

 

[tweakradje]

@__PG__ In the last RR version there are light libs from other phone. These require other permissions on these files:

#LED
chown system:system /sys/class/leds/*/brightness
chown system:system /sys/class/leds/*/blink

The zip file you mentioned overwrites the V3 script. (open the zip file and look in etc folder)

If you want to use my init.qcom.post_boot.sh script you need to add the 2 lines to it at the end before using it.

Cheers
