[Q] Hard bricked Z2 - Xperia Z2 Q&A, Help & Troubleshooting

Hello,
I tried to flash Lollipop from another Z2's Nandroid backup. But Only thing I got now is blinking red LED when I connect phone to charger or PC (Flashmode and fastboot dead).
All the tricks with buttons I already tried. And after that I dissasembled my Z2 to try pull out battery - nothing.
After that I found out, there is a Testpoint and when I ground it I can connect to PC as SOMC Flash Device but I don't have any SETool stuff and something like that.
I tried to use S1tool from 28.2.2015 but it still doesn't support MSM8974-AB only MSM8974.
Thanks for any advices.

Yes, phone doesn't react. Tried all buttons tricks even with rubber band on it for all night. Only flashing mode I can achieve is trough testpoint.

No idea about the jtag thing but I think this is the test point for the Z2, I connected it to PC and all other points give no change, but this one turns the led off when grounded by touching the metal shields with a paper clip.
If I'm wrong then OP please correct me.
Also am patiently waiting for an update to S1 Tools for our d6503/2, there's plenty of hard bricks qwith unfortunately no solution unlike other Z flagships.

hard brick z2
yep i tested it also and the only change that i could get is just that point that u mentioned , was in city searching for some one to fix my phone he said hes gonna charge me 50 dollar to fix my phone without even opening my phone with heat ( already opened it : / ) , when i asked him whats this about and how could u fix it he said it s a new way that came for z2 and i could get ure boot back up again , hopefully i will go there in 2 or 3 days to see if his right , will let u know if i fixed the phone and hopefully i could ask him about the way that his doing it : )

No, even two services couldn't fix it. Waiting now for new S1tool

Refresh

Don't know about Sony repair service, just tried some unofficial services and nothing. All I got is only flashing with testpoint but for this you need some flashing box like Octopus box or SETool. Also exists alternative - S1tool which is free but now works only with Z1 and older models.

---

refresh

how could restoring another nandroid or carbon rom cause a hard brick?

---

I don't know. It was 5.0 backup from another Z2 (same model) and i had 4.4.
