How to install Custom ROM CM 12.1 Lollipop 5.1.1 with Phillz Recovery and Root i9192

[gauravjot]

Hi, everyone I have recently did Custom ROM CM 12.1 Lollipop 5.1.1 on my Samsung Galaxy S4 Mini I9192. So for complete steps how to do it, Follow the Steps -

Strictly for I9192 Devices

Be noticed that it will void your warranty and your device may get brick during process. Also keep your battery fully charged before doing anything. I am just showing you things to do, in any odd situation YOU ARE RESPONSIBLE for damage.

For all the steps below use genuine USB cable comes with your device.

Start By Installing Phillz Recovery on your device. Here it is how

1. Download philz_touch_6.48.4-serranodsub_AndroidTunado.tar and Odin
2. When your phone is full charged, turn it off.
3. Enter Download Mode by pressing HOME + VOLUME DOWN + POWER KEY.
4. When download screen will appear open Odin and connect your phone to computer with USB Cable.
5. You will see your device detected as "COM:*". In Odin, do not change any checkbox settings and click PDA or AP (whatever available) and choose Phillz recovery "philz_touch_6.48.4-serranodsub_AndroidTunado.tar" file.
6. After choosing file, click Start Button to begin downloading in phone.
7. Your phone will reboot automatically and Phillz Recovery willl be succesfully installed.

So we are done with custom recovery. Next step is to install CM 12.1 . Again charge your battery if you lose any during Phillz Recovery. For download CM 12.1 and Gapps follow this post - http://forum.xda-developers.com/galaxy-s4-mini/development/rom-cyanogenmod-12-0-s4-mini-duos-gt-t2950526 (Big thanks to @k2wl).

After downloading, paste both .zip files to SDCARD. I recommend to paste both in internal and external memory in case.
Before installing ROM must do a backup of your device, install Nandroid or Titanium Backup from Google Play and get a full backup of your system and data. You need almost 4GB of space in external SDCARD to do so. Don't miss the backup as it will be only way to get you back on working phone if any failure occur. (Copy on computer as well to get secured)

So we are ready to install CM 12.1 yay! (Unlpug USB Cable if connected)

1. Boot your device into Recovery Mode by pressing HOME + VOLUME UP + LOCK BUTTON
2. From there wipe the system and clear cache: “wipe data factory reset”, “wipe cache partition” and “wipe dalvick cache”.
3. From main menu of recovery select “install zip from SD card” and “choose zip from SD card”.
4. Pick the cm-12.1-20XXXXXX-UNOFFICIAL-serranodsdd.zip file from SDCARD and install it.
5. When completed, DON'T EXIT/REBOOT, press again install zip from SD Card and choose gapps zip and install it.
6. When done Reboot your device.

There it come cynogenmod icon on bootup of your OS. Congrats CM 12.1 is installed. You can go to setttings and see version 5.1.1 of android working!

Don't forget to follow changelog of ROM for new nightly infos: http://www.cmxlog.com/12.1/serrano3gxx/#next_build

So follow rest if you want SuperUser in your device. Please note if you don't want superuser and yet Root access you have inbuilt in ROM at Settings >Developer Options > Root. Only follow below if you want SuperUser Application to have control over root access.

1. Download SuperSU-v2.46.zip file (from attachments) and put in your SD Card.
2. Again bootup in recovery mode HOME + VOLUME UP + LOCK
3. Choose "Install Zip from SD Card" and choose SuperSU-v2.46.zip
4. Install the package
5. When done reboot the device and you have SuperUser installed

Enjoy CM 12.1 with phillz recovery and ROOTED. Keep in mind its just a tutorial. I take no responsibility of ROM or softwares attached. For your info, everything went perfect for me on my I9192. Let me know how your experience went!

Special Thanks to

ROM Performance as CM12.1 Nightly 3 July

ROM is almost stable and you may not have any trouble with general usage. Calling, Messaging, Wifi, Bluetooth, Radio almost everything is working. Camera quality is same as on stock and with same upto Full HD Recording. UI is more faster (thanks to no bloatware) and new settings for many new lollipop features and developer options. Battery life is same as stock (Falls to 20% after 3h 52min Screen Uptime with moderate usage with games and music playback). I haven't find any difference in battery yet using for 10 days. What I find is needed to improve or buggy are following

• Random Force Closes - Few Apps (not all) get closed automatically. I often use a music player (debug version as I am developing it) which automatically closes after some time. (Maybe force close only for debug or non play-store apps, not sure, let me know about your experience) (Seems solved in newer update)
• Games are not as fast as Stock Samsung - Heavy games like Asphalt 8 loses frames which is not with stock ROM. Sometimes Clash of Clans too behave a little laggy (once in hundred times).
• Earpiece Speaker - I don't know if their is problem in my network provider or phone but 1 in 10 calls I can't hear anything what other person is speaking while connecting headphones give response and normal sound of caller. Tell me if it's same with you or I got problem at connection ?!?!?! Really annoying. (Most probably working 100% in new update as told by @roshanu)

Issues are being detected by @k2wl and improvement is going on everyday. You can upgrade to newer ROM when any comes out.

This post may get outdated anytime when ROM will be improved. To know what are changes in new nightlies, follow ROM Download Link > Changelog

Tell me what are new issues or if any old issues get resolved. Thanks everyone

Thanks to @roshanu for reminding of this post.

I am on July 10 version, installed using CWM recovery. Been two days now. Pretty basic use: no gaming no music.
ROM is stable so far, no force closes.

+1 on the light sensor.

Haven't had any problem with the earpiece speaker.

It seems root access was getting disabled on reboot, not sure. Also there was no SU app after the installation.
So I enabled the root for apps and adb through developer options, then installed the SU app through Play. Working fine now.

Will update new findings, if any...

Do you know if 4G LTE can be enabled on our phone i9192, or even future possibility ??

It's good that developers are working on ROM and issues are solved pretty fast. For SU app you have to flash the SU zip file (in attachments) in download mode (by pressing [Volume Down] + [Home] + [Lock]). And sadly 4G LTE depends on chipset and hardware, not on software, so it can never be more than HSPA+ in any update. Do post any issues or any new improvement, it may help developers
