Yesterday I was trying to install a stock rom, with the stock recovery, but suddenly at 30 or 40% it just made a reboot. I had this simptom of boot loop even before, but plugging it to the power bank, was solving the issue, so this is why I am thinking that is a battery issue, and even before, it was always failing to install anything from odin, as it was re-booting after a while ...

So it is either the phone which is dead, or the battery. Let's hope for the second one ;)
Lets wait and see. I will wait for updates :).

Hi there ... it was really the fu##ng battery. Every time I was installing something it was reeboting and that was screwing up everything ...

BTW I am still not abel to install the stock rom, but at the moment I don't care, I've been able to install CM and this is more than enough. Thanks a lot anyway for the support.

Cheers

Steve

ODIN METHOD

NOTE: With the following method you can't install Gapps. If you wish to install GApps you must install them with a custom recovery and by following the FLASH USING CUSTOM RECOVERY METHODS post. Same goes for the super su.

INSTALL PROCEDURE
1) Boot into Download mode. (In order to do so, press Volume Down (-), Homebutton and the Power-Button at the same time untill you see the Green warning screen. Then press the Volume Up).
2) Connect the device to the computer.
3) Open Odin on the computer.
4) Check if your device is being recognised on the top left of the Odin window. There should be displayed something like (e.x. 0:[COM3]). (If nothing is displayed, you propably didn't install the Drivers or you installed the wrong ones)
5) Make sure that only Auto Reboot and F.Reset time are ticked.
6) Press ONLY the PDA button.
7) Browse to your downloaded file (e.x. ROM.tar.md5).
8) Select it.
9) Press Start.
10) Wait untill the device reboots and on the top left is displayed one green box saying PASS!.
11) Unplug the device from the computer.
12) Immediately remove the cover and take out the battery.
13) Wait 5 secs and then put it back again.
14) Boot into recovery mode. (In order to do so, press Volume Up (+), Homebutton and the Power-Button at the same time untill you see the S3 Mini Logo, then release the Power-Button and keep pressing Volume Up (+) and the Homebutton)
15) Wipe data/factory reset.
16) Wipe Cache partition.
17) Press reboot system now.
18) DONE!

Hello! Thanks for such a brief and awesome guide!

I have an issue with my I8190 when booting the custom rom for the first time, it won't pass the boot animation. As soon as it flashed, the phone will automatically restart TWO times, the first time it will show the model logo and then it will display a green android for 1-2 secs., then it restarts again and the boot animation (blue CM alien in my case) remains forever.

Any hint? Thanks!

This is a common issue and it is called bootloop. Try to flash a custom recovery first via odin (the instructions are in the op) and then try the custom recovery method No.1. Let me know how it goes.

    Hello guys,

    As you may have heard the clean installation, is a method that wipes all your device's DALVIK CACHE, SYSTEM, CACHE, DATA and INTERNAL STORAGE partitions.
    YOU DONT HAVE TO WORRY ABOUT MAKING THE PHONE UNSUABLE.
    By wiping SYSTEM partition, you only wipe the old ROM's files. The new ROM will genarate new proper files.
    By wiping DALVIK CACHE and CACHE, you just clean the old " mess" of installed apps etc.
    By wiping INTERNAL STORAGE and DATA you DO delete all of your personal files, apps, phone contacts etc.

    UNBRICK

    NOTE: Please be sure that your device is bricked. To know if your device is bricked, your device should not boot into your current ROM at all and at some cases not even on (Custom) recovery. In other words you suffer from what is called bootloop.
    If you are able to boot into your already flashed custom recovery use the FLASH USING CUSTOM RECOVERY METHODS and flash your custom ROM to regain access to the phone.
    If you can not boot into your custom recovery but you can boot in download mode the problem is repairable. Be sure that you have the original recovery installed before you flash the Stock ROM because some roms don't include it and it may cause some issues.
    If you can not even boot in download mode then your device is hard bricked and you must use an usb jig in order to make your device boot into download mode(ONLY) again. If at the end, you still can not boot into download mode then there is nothing you can do from a software-side


    Download the stock rom you need form here: www.sammobile.com and unzip it on your computer.

    UNBRICK PROCEDURE
    1) Boot into Download mode. (In order to do so, press Volume Down (-), Homebutton and the Power-Button at the same time untill you see the Green warning screen. Then press the Volume Up).
    2) Connect the device to the computer.
    3) Open Odin on the computer.
    4) Check if your device is being recognised on the top left of the Odin window. There should be displayed something like (e.x. 0:[COM3]). (If nothing is displayed, you propably didn't install the Drivers or you installed the wrong ones)
    5) Make sure that only Auto Reboot and F.Reset time are ticked.
    6) Press ONLY the PDA button.
    7) Browse to your downloaded file (e.x. ROM.tar.md5).
    8) Select it.
    9) Press Start.
    10) Wait untill the device reboots and on the top left is displayed one green box saying PASS!.
    11) Unplug the device from the computer.
    12) Immediately remove the cover and take out the battery.
    13) Wait 5 secs and then put it back again.
    14) Boot into recovery mode. (In order to do so, press Volume Up (+), Homebutton and the Power-Button at the same time untill you see the S3 Mini Logo, then release the Power-Button and keep pressing Volume Up (+) and the Homebutton)
    15) Wipe data/factory reset.
    16) Wipe Cache partition.
    17) Press reboot system now.
    18) DONE!


    If everything went as it should you should now have stock rom with stock recovery installed.
