Death S4 mini / hard brick

[alex27riva]

Hi, suddenly my S4 Mini crashed and it doesn't boot up anymore.
It doesn't enter into recovery mode, but enters into download mode.
So I flashed i flashed the stock firmware via Odin and the procedure freezes in the beginning, so i tried 2-3 times and now my phone is a paperweight, completely dead.
How can I fix it? the JIG USB will resolve the problem?
Thanks
Bye

I got same issue 1 year ago. My phone getting Samsung logo and restarting all the time. I flashed many roms in 1 day. Phone getting hot while flashing rom. Also weather is too hot. Unfortunately i burned my phone's hardware partition (I think I burned baseband).
I thought I gave my phone to phone repair shop which has jtag. I don't want to gave it Samsung service because I lost my guarantee with rooting it. But my father said "you already have guarantee. 2 years didn't exist after you bought your phone. You should gave your phone Samsung service"
I gave it to Samsung authorized service. I said that I was upgrading my phone via Kies. (I was too excited while I was saying this) After that my phone couldn't turn on. (I know I told lie but I need to get fixed my phone without money ? )
After 3-4 day i went there again to take my phone. They gave my phone and told me "your phone's mainboard and sub (charging input socket) were changed.
I was shocked ?. They didn't controlled my phone if it was attained knox counter.
Sorry for my bad English.
Maybe I can't help you but I wanted to share this event that I lived it.

Same thing happened to my S4 mini Duos on 11th February. My phone was on Stock Samsung Firmware, Custom Recovery, Custom Kernel, and of course rooted.
I changed to stock in December. It was working fine for a month. I texted my friends and after 15 minutes I took out my phone to make a call and I found it was powered off. Then I tried to power on. No response. Then I charged the battery using external battery charger as my phone was not showing charging logo.

After some time, it showed logo and entered Download mode. But didn't enter Recovery mode.

I did a complete flash (nandroid erase all) through ODIN. Not entering custom recovery as well as stock recovery. It shows "recovery booting" but restarts right after that. Stuck on Samsung logo. Just vibrates and reboots again and again.

I gave the phone to a Samsung Authorized Service Center, they declared my phone as hopeless. They say the motherboard is faulty and it needs replacement.

I never even dropped my phone or overclocked the cores. I had been using it gently. I really don't know what to do now. Here I am, looking for a solution.

So, I see that there are more and more people with a same problem and there is no clue what is the cause of the problem. I started a topic with a same question about month ago, but without any reaction.

Hi... I got something similar going on.
Samsung s4 mini running CM13 NIGHTLY (cm-13.0-20160214-NIGHTLY-serranoltexx.zip) Yesterday, I Downloaded Feb 18th nightly and decided to update other apps as well.
Today, as I updated some apps on the play store and got "insufficient message". Decided to make SD Card part of internal memory. Went thru the process and it transferred about 3GB into the SD Card. Afterwards, I proceeded with the CM update. A small screen came up saying it was preparing for upgrade and then it rebooted in recovery, as usual, but this time it blacked out. It just wont go into recovery mode.

Should I try to boot with a different SD Card with the CM update? Is there a way to do it on download mode?

Any suggestions would be great! thanks
