H9436 Stuck in bootloop, possible to rocover any data? - Sony Xperia XZ3 Questions & Answers

Hi,
I've run in to some problem with my XZ3, H9436. I was restarting my device as i do from time to time but this time it got stuck on startup. I goes on normally until it starts showing the "xperia" logo in different colours and just freezes for some time and then reboots and it keeps doing this until i force it off.
I've tried to get into recovery mode by holding down power+volume up but to no avail. (Maybe it's the wrong combo?)
When the phone is connected to a windows computer it is being seen by the pc.
Pc companion sees it but don't allow me to do anything since the phone is locked.
The only option i can use in pc companion is the factory reset but that deletes my files and there are some .gpx files i would like to recover from the phone.
Am i out of luck or is there anyone who has any ideas that could help me get my files of my phone?
//N
EDIT: Of course i would like to be able to repair the current system and not reset everything, but that might not be possible? But if it is that would be great.

[HELP] [URGENT] Xperia Z won't open (restarts contionusly) but...

An hour ago i have changed my customization number in build.prop to get updated and now my phone fails at restarting. after sony logo a blank screen comes up and then phone restarts again. boot animation don't show up.
Actually i didn't rooted phone. Like didn't fully root. An exploit that does it without unlocking bootloader. I was able to run root required apps but when i was trying to mount r/w mode, the phone was restarting itself before i do something. So i copied build.prop to another place, changed it, then in root explorer copied to /system. I managed it to owerwrite before phone restarts. When phone shutted down, didn't open, stucked at that point. Keeped restarting.
I know a lot of questions, topics opened about this but almost every solutions says that "repair over sony pc comp" or "repair over SUS". I tried both but in pc comp, program couldn't find my phone because it's turned off. when i open phone and connect wire it finds the phone but before pc comp finishes connecting phone restarts again. And in the SUS, i managed it to go into flash mode (volume down key and then connect.) It has found the phone (however green light didn't come out, no LED color was there) and SUS said there is no update for my phone, it's up to date. There is no repair button.
Besides there is another solution, flashtool. Will i lose my data if i use flashtool? I'm able to go into fastboot mode (blue light).
What can I do?
Update
Guys i can't belive now... Somehow i installed CWM recovery on my bricked xperia z. Now taking backup but the problem is when i connect to adb when phone is in CWM recovery mode i can't reach internal sd. WHY???

Process System is not responding + Bootloop

So last night I turned my phone off and put it on the charger. This morning when trying to boot up I get an error that process system is not responding and whether I choose wait or to close the program, after a few moments the phone reboots itself. The only way to fully turn it off is with power+volume up. I can't do a factory reset or anything involving an internet or cell connection on the phone. When I try to do a factory reset It will tell me system is not responding and reboot again. I have a Tmobile XZ C6606, and I am using xubuntu 14.04 right now. Any help?
EDIT:
Also I have manually uninstalled all downloaded apps and I have booted into safe mode and the same thing occurs

Screen Goes Black after Reboot

After my phones battery was fully drained, i kept it for charging and after some time when i tried to restart it
Boot Logo animation appeared, then whole screen gone blank. It just shows the active notification icons and when power button pressed it shows power off option.
I am having the exact same issue. Have you had a luck resolving it?
My phone battery died last night. I plugged my phone in, let it get about 15% charge, then tried to turn it back on. The phone boots like normal, but after the boot animation goes away, the screen is black. Active notifications still seem to work, and I can hold the power button to get the Power Down option. I can boot into the bootloader & access recovery just fine. However, my phone is fully stock (no root, no bootloader unlock, no anything). I can't seem to access ADB when the phone is powered normally (ie, when I'm at this mysterious black screen), but it's possible that USB debugging isn't even enabled.
So far, I've found a few people who've said a full factory reset will fix the problem, but I'm looking for another solution, or at least a way to grab my data before I reset. Since my bootloader's still locked, I can't seem to use fastboot boot to boot into TWRP, and I can't find any other way to access my data to copy it off the phone. I've tried wiping the cache using the stock recovery to no avail. Any suggestions?
I had to factory reset my phone.. There was no other way to solve that issue, no other forum moderator is providing solution. There are many threads regarding this issue. Lets hope next update comes soon fixing this issue.
Hmm, ok, thanks. That's probably what I'll resort to doing. I was hoping to find a way to not lose my data. Or at least get a copy of some of it before resetting...
Me too have tried many things for not losing data, my usb debugging was also enabled. But pc didnt recognized any device. There was one article regarding recovering data after factory reset but you need to root your device after u reset ur device. Then you can recover data with DrFone data recovery or Es android recovery. I avoided it because i dont want to lose my warranty.

Is my phone hard bricked? h81120p

Recently I was running Prometheus custom rom, until it started actin funny, so I attempted to reflash cause the phone was getting slow over time. Tried reflashing but it didn't work. Tried other custom roms but each and every one of them kept saying * such n such isn't responding... System UI isn't responding, etc* unbearably slow, I no longer had landscape, sound, and the flashlight didn't work.
re-flashed the h81120N kdz with lg up tool, and the phone initially wouldn't even start, had to re flash 3 times before my phone said I had some upgrades... so it upgraded me to h81120p. Phone ran like a charm and I got all functionality back.
I attempted to at least re root h81120p, it initially worked then the next day I take phone off standby, and it turns off and wont boot past the LG logo screen. if it does the screen goes black. I put the phone in download mode and run lgup, and reflash with a stock h81120p kdz.. sh1t still doesnt work, tried again, sh1t still wont work. ' ventually, phone stopped staying in download mode, and when it does finally get there, LGup no longer recognizes its plugged in * please connect handset*. TF? computer only recognizes "Qualcomm HS-USb QDLoader etc.." under "ports"
Did some googling and was linked to LG flash tool and to a site on here for a .tot restore, which linked to some Vietnamese site I cant read, and one you have to pay premium vip in order to download the file, file seems to not exist anywhere else on the net.
so here I am... Phone barely stays in download mode, when in download mode, ( after multiple attempts of removing usb cable and battery, holding up on the phone while trying different combos of plugging in phone/ cable)LGUP doesnt recognize it, phone does not boot past the Lg logo , a factory reset does nothing.
first my laptop fails, now my phone is gone. wtf? can anyone help?

Question Redmi Note 10 Pro - Stuck on Miui Logo

Hey,
I know there's a fair few threads on this but I've spent the past 7 hours trying to resolve this with all ideas I've found although to no avail.
My phone was on, working as normal although randomly it is now stuck on the Miui logo no matter what I try. It also freezes on fastboot.
The phone isn't detected by the PC now anymore either, the phone is only 6 months old.
Does anyone have any other ideas what I can try?
I've tried safe mode, reboot, fastboot, connecting phone to PC, having someone call me etc, no luck.
Fastboot is not "fast boot", it is a mode to install parts of the operating system from PC.
If your bootloader is unlocked, (unlocked lock icon at the top of the screen when starting the phone) you can download MIUI (Fastboot version) from https://xiaomifirmwareupdater.com/archive/miui/sweet/ and then extract the archive, and run the flash_all_except_storage.bat file from PC while the phone is in "fastboot" mode and connected to PC via USB.
If your bootloader is locked (no lock icon when starting the phone), then I'm afraid you're gonna have to reboot to recovery mode (hold power button+ volume up when restarting the phone) and select wipe data option which will erase all data and "factory reset" it. If that does not work, then MIUI is corrupted and you have no choice but to visit a Xiaomi phone service center.
You're in luck if you live in europe or china, since there are many official xiaomi stores, but if you're in america, there are currently no official xiaomi stores sadly.

....Boot problems can also have something to do with defective hardware buttons.

Enter recovery. (hold volume up and power) There is an option to reset data there. It will wipe the data in your phone, but should start you from scratch.
