So, yesterday my phone turned off on its own and keeps rebooting and gets stuck on lockscreen for 5 seconds until it reboots again. When I try to factory reset using TWRP or OrangeFox, it keeps telling me that my data partition is corrupt. And my phone wouldn't boot for this reason. I've even tried flashing fastboot rom using mi flash tool but the problem persists. Any help would be appreciated.
P.S: I got my motherboard replaced in January as my phone was under warranty. So, I'm afraid it could be a hardware related issue.
If your phone is still under warranty try to have it looked at. Sounds like a HW issue.
Yes it should not crash right after clean flashing fastboot MIUI

So my friend's phone died during a software update which completely messed up his phone. I thought it would be a simple fix, no problem, but there is hardly any valid information out there that can help me (due to a lot of dead links). Here's the issue:
The phone (SPH-M950 btw) loads the initial "Samsung" image on the screen. Then it goes away and starts to boot up with a blank screen. My computer recognizes the device until a couple seconds late the phone restarts itself and continues this boot loop. I cant boot into the stock Android Recovery but I can boot into Download Mode. I've tried for hours to flash all kinds of ROMS with Oden but, despite the fact that Oden says everything worked, it still continues the boot loop.
If possible I would like to get the OS to work again without losing any data. If not then I would at least like to get the phone to return to it's OOB state so it's at least functional.
Help please?

Did you try to access the recovery mode after you flashed anything?
Try it and check whether it works. Then try to format /system /data and /cache (internal data will be lost) and then reflash stock rom via Odin.
Then try again.

I forgot to talk about accessing recovery mode. All that happens an Android logo pops up and starts to look like it's loading the recovery os but then the phone just reboots again and continues to do the boot loop. Nothing changed no matter what custom recovery I flashed.
I would have no problem if I could just get into the recovery menu but that's my biggest obstacle.
Sorry if I broke any rules, first thread in XDA.
Have an old Z Ultra that was having sim slot issue, It was belong to my bro who recently upgraded to another phone. I factory reset it to wipe any user data or bugs that may cause by 3rd party softwares. immediately after reset, it went to bootloop, it will either stuck just before fully loaded into Android system or just after it. I can't seems to boot to recovery or bootloader to check anything, when pressing the down button with usb cable inserted, the green led blink for a split second then nothing. flash mode with blue LED is fine, I can flash ftf. I tried with PCC repair, the process completed, updated to latest 5.0.2 but again, bootloop, updating Android took dozens of reboot/bootloop to complete. the first time I tried, it managed to boot normally and I could do some setup but when I tried to shutdown, it took forever, so I do power + vol up to force shutdown...the bootloop came back and never boot normally again. I had tried using flashtools with a few different tft, the same thing, bootloop. this is one of the ftf : http://forum.xda-developers.com/showthread.php?t=2798690
I had read a few threads in Z ultra section, many suggest to flash a ftf or PCC repair, most managed to solved with the aforementioned but not me. I didn't root or unlock the bootloader before, never tried any tweak to the system or any thing that might cause system corruption, ONLY factory reset. is this some hardware issue? but why only after factory reset? had tried several ftf, still the same bootloop. unless the issue is cause by recovery or any other hidden partitions/system that the ftf I tried didn't flash? battery is >80%. no sim I still can use it as display but bootloop, this is as useless as junk.
Anyone can offer a way to fix this?
TIA
i had my amaze repaired (power IC, bad data cable caused it to not charge or even boot up or go in bootloader). Now within 30 seconds off booting up it used to restart. and i cant get into the recovery( shows logo and powers off when going into recovery from bootloader). i cleared the cache from bootloader and its now stuck at boot animation( not boot logo) and wont boot completely. before clearing cache after logo it used to show 4ext recovery boot screen then screen off, now it just shows logo and screen off. really need help i got this phone fixed after 1 year. im s-off and running any 4.4.4 rom (dont remember which rom, i think pacman rom)
so basically i can get into bootloader and use fastboot commands (no adb, authorized device). cant do anything else on the phone. is there a way to fix the phone?

reflashed recovery for the 4th time and it worked. it said the cache partition is corrupt. formatted it. phone works now. updating apps caused system ui stopped working error. going to flash other roms.

Glad you got your phone working--your persistence paid off.
Be sure to make a backup before flashing other ROM's.
I think I have accidently erased EFS partition and I have no back up. I have seen a guide for restoring them for the redmi note 3 but nothing similar for the redmi note 4. Can anyone help me. I can install the official rom and an unofficial rom but the phone is in a constant bootloop and just restarts after 1 minute.
Just to add, I can't understand why it is bootlooping every minute. It means I can't do amything with it before it restarts. Adb recognizes the device and i have been able to get in long enough to see both imei's are gone. I get that I have wiped them but I don't understand why it is constantly bootlooping even after I put the official global rom put on and relocked it. After it went bad it would load recovery and fastboot but the screen was blank so I didn't realise at first until I noticed it was connected to Adb. Installing the global rom restored the recovery and fastboot screens but didn't help with the bootloop. If I could fix even just the boot loop it would be a start. Any help would be most appreciated even if it is just to tell me it is a lost cause.
I Downloaded LineageOS (Unofficial) from this link => https://sourceforge.net/projects/harukeys-roms/files/laurel/LineageOS18/, Wiped everything with TWRP, ADB pushed the file from my pc and flashed it with TWRP, the OS booted normally, but WIFI didn't work, so I decided to reboot the phone, now the screen is completely black, won't respond to charger or power button, can't boot to recovery/fastboot, is there anything I can do? If it is indeed hard-bricked what will the fix cost be?
Plug your device into your computer and see if it detects it.
Also try putting the device into EDL mode and connect to a pc and see if it is recognised.
If it is recognised you can use mi flash to flash the stock firmware back to the device.
Also what exactly did you wipe in twrp? Did you wipe persist partition and everything?
If yes than you may have to replace the motherboard because without a backup of the persist partition there is no way to return it to its original state which may render sensors and radios completely useless or worse, a hard brick.
A bit more info on what exactly you did would be helpful in diagnosing exactly what is wrong and how you can proceed.
What's strange is you said it booted the first time and then fails to boot afterwards.
