Here I'll write down a set of Q&A about the S4 mini, flashing, etc.

(If you like to provide extra information or have a correction, I'll add it to the OP)

Disclaimer:

I'm not liable to any demage to your device, including Knox. The information here is as good as I know, there is no guarantee.

- How to enter recovery?

- Power the device off and press volume up + home + power for a while​

- How to enter download mode?

- Power the device off and press volume down + home + power for a while​

- How to root?

- This is one method, there are many though (this one will trip Knox): http://xdaforums.com/showthread.php?t=2364980​

- What is Knox?

- Read here: http://xdaforums.com/showthread.php?p=52855637​

- My device is bricked help!

- Follow this thread: http://xdaforums.com/showthread.php?p=52648525​

- How to flash something with Odin?

(If not described differently, follow this)

- Make sure you've enough charge on your phone, min 40% is usually safe

- Put the .tar or .tar.md5 file into PDA or AP (it's the same, it's just different in Odin versions)

- Boot your device into download mode (press volume down + home + power at the boot process for around 20 seconds)

- Connect your device (Odin should say "Added")

- Click "start" (Do NOT disconnect your device or power off your computer in the flashing process, it could hardbrick your phone)

- Wait until your phone has fully rebooted

- Done (If you've trouble with booting into the system after a flash, do a factory reset in the recovery)​

- More flashing information: http://xdaforums.com/wiki/index.php?title=Flashing_Guide_-_Android​

- My signal is bad etc. from the very beginning I have this phone, what can I do?

- Return to seller before Knoxing it up (don't flash anything and don't try to repair it on your own)​

- Will the s4 mini forum get more users any day, also more roms etc.?

- Yes, I'm pretty sure, the device got intense price reduction since the S5 was released, so more people could afford it​

- I don't like the keyboard of my AOSP rom, is there a better one?

- Look here this is the Xperia Z2 keyboard, it works for s4 mini (Flash the flashable .zip not the single file): http://xdaforums.com/showthread.php?t=2708805​

- Can I flash Cyanogenmod with TWRP?

- It worked for me, even though the Cyanogenmod team doesn't recommend it​

- When I boot my device I see colored pixels lightning up after the splash screen, is my device now totally broken?

- No, It's stuck in a bootloop, but the lightning pixels are not to worry normally. You've to unbrick it.​

- My device is heating up, do I have to worry?

- Mine does too, and I'm not worrieng​

- How to enter to enter extra-developer settings (For example performance settings (set governor etc.)) in AOSP roms?

- Tap the build number in the phone information menu 7 times (It should say "now you're a developer") Then after that you'll find more menus in the settings​

- How to easily access the hidden service menus?

- Download this: https://play.google.com/store/apps/details?id=com.kabasoft.util.servicemodeshortcut&hl=de (In AOSP rom's probably only the "Test menu" works, because others are blocked)​

- How to change CSC?

- Get this app: https://play.google.com/store/apps/details?id=com.manniakk.cscselector&hl=de​

- How to safe battery without loosing performance?

- Deactivate syncing services (Parts of Googles services etc.) which you don't need, or pick another governor and i/o.​

- My battery doesn't work properly and I've my phone for more than 1 year, what can I do?

- Batteries don't have a long lifespan, your battery is most likely demaged. You can use this app to view what the system says to the battery health: https://play.google.com/store/apps/details?id=com.cpuid.cpu_z&hl=de​

- Where to download the latest stock firmwares?

- www.sammobile.com or www.samsung-updates.com (Sammobile is recommended)​

- Can I return to stock after flashing a custom rom?

- Yes, but remember you cannot reverse Knox so far! How to reverse to stock: Flash a stock firmware with odin, enter recovery and do a factory reset. (Stock firmware links, above)​

Hello, thanks for your advice. Please could you answer this for me. I currently have an s3 mini and love flashing custom roms etc. I am thinking of buying an s4 mini on contract with o2 service provider. If i buy this phone and the bootloader is locked will i be
able to unlock the bootloader?

Search online for "repair firmware i9190" I think it was available, I'm not allowed to link it since it's for premium download only. Once you got the file, share it with us. I don't have it.

You can not install roms from other device. The system will boot bu you will have no radio function(gsm, mobile data...)

I am new to android and i have s4 mini i9190 which had stock rom 4.2.2 jelly bean.
four days ago i installed TWRP using odin but was so scared to install custom rom. Anyway i still made a back of everything(modem, EFS, Boot, System, Cache, Preload and Data). Two days ago i installed CM12.1 and i really liked it but the problem is camera. The pic captured while recording video is in low resolution compare to stock camera. so kind of slow too.
Can i go back to jelly bean using the restore without any problem?
and which restore option should i leave checked.
My knox is 0x1.
Can someone please help me go back to stock rom?

 

[juanpabloml]

A question the system format is required to install the rom ??

 

[ugynok]

Do anyone know when they stopped producing i9195 and i9195i ? I need to buy the latest version, because my i9195 was made in 2013 and have that battery drain issue even with new batteries...
