Nokia reboot problem when trying to update

Hello!
I have a strange problem with my phone it wont update to latset firmware without get in some kind of boot loop.
The phone was runing the lastest firmware 1232.5962.1314.0017 before the problems started, it all started when some systems apps like camera, settnings, messeging. etc, stop working. All that showed up when entering the apps was a black screen say something like "reconnecting" and then it jumped back to home screen.
So I restarted the phone but then went in som kind of reboot loop where it wouldent go past the nokia logo. I tried everything soft reset, hard reset. The last thing I tried was to reflash the phone, I tried diffrent ROMs and it finaly worked with the ROM 059Q5C6 RM-821 GLOBAL BLACK SWAP.
The phone is runing now and almost all functions work exept camera and automatic brightness (all that I discoverd so far).
Its currently running the 1231.5951.1249.1004 firmware.
But like I said now when I try the update the phone it goes to the same boot loop state.
What should i try next?
Is the thread in the right place?

Same thing happens to my phone!! Did not think that it could be the latest firmware (1308 for me) could have caused it since I don't think there are a lot of us affected by it and my phone has been running fine for months after the update! I've restored 5 times, by the time I thought to flash it, it wouldn't charge anymore.... I'd sent mine for repair now... Have you fixed yours?

S6 edge g925f freezing on system but stays on recovery

Hi
I'm sorry if this isn't the right place to ask this
I have bought a used S6 edge yesterday and that phjone was restarting and hanging some times and freezes forever. sometimes it restarts automatically but sometimes I have to restart it using button combo.
I have flashed Factory formware combination and it worked realy fine. nothing hangs and also stable (than the normal TW)
I have tried TWRP and it also works fine stays in recovery mode as long as i need without hanging.
So this hangs only on TW system
Please be kind enough to give me a solution
In sri lanka it costs arround 55000/= for this model. Unfortunately I do not have any warranty for this. And that was # months of my salary :crying:
EDIT : Tried flashing custom roms. Nothing changed
Tried flashing factory binary (borrowed from a friend) works fine without lagging. No any error on that.
Tried flashing official nougat again. Frozen at setup and remain rebooting...
Please guys help me.... :crying:

Try a different stock firmware just to be sure it's not corrupted.
Which custom rom did you Try?

Boot loop

Hello. I have a boot loop issue with my SM-G850F. It happens immediately after camera launching, boot loop can last for minutes, but eventually the phone turns on and works alright except camera. Sometimes camera may work fine for some time but later it goes to boot loop again. Also if i restart my phone manually it also goes to boot loop. I tried to reflash it using Odin, different firmwares, home and factory, Kitkat and Lollipop, i did it with data and cache wiping from recovery every time. When Odin finishes it's job and a phone tries to reboot after reflashing - here boot loop starts again. But when i reflashed 4.4.4 and got a Lollipop OTA update, my phone got back to life, camera worked fine, it restarted fine with no boot loop anymore. But after about 6 months it happened again. The same situation, wiping didn't help, reflashing didn't help, and again reflashing 4.4.4 + OTA update did help, i don't know for how long. What may be the reason? I assume it's not a camera problem, OTA update shouldn't fix it, and it's not a battery for the same reason. What do you think?

Maybe a hardware issue? Did you try ozcan or epsil rom? Do you have the same issues on those roms?

After several hard resets the problem has gone, i don't know for how long though. So i have no idea is it a hardware issue or not. May it be a flash memory problem?

Samsung J7 Prime G610Y No Service Auto Restart

it is in Nougat 7.0. I was trying to fix No Service issue by trying to format, hard reset and reflashing stock rom (not a newbie for flashing) but nothing works. As I was done with that i notice when i use it, it automatically restarts at exactly after 15 mins, first its slow down, got hang then restart then after restart as soon as it boot up to the Samsung logo it hangs up and never complete the boot unless you force restart it then it boot up normally, then after 15mins same goes again.
The No Service issue, when i inserted the Local sim there is no signal no matter what. tried to fix it using Z3X Samsung tool pro v29.5 but i guess it doesn't support G610Y yet but rather in higher version. By fixing Auto restart i tried flashing stock rom both Marshmallow and Nougat version. Please help me and will greatly appreciated.
Must be careful choosing Stock Firmware next time, I've got the wrong firmware and of course it's not compatible that's why it Auto Restart on its own. About the No Service issue I've tried using "Z3X" Patch Certificate done but didn't fixed it so it must be a Hardware issue.:good:

Galaxy S9+ G965F Bootloop problem, need help

I woke up with a black screen and unresponsive I soft reset and booted back up just fine, fast forward 2 days, apps are constantly crashing and often seemingly randomly the phone will restart and go into a bootloop anywhere from 1-5 minutes before it finally boots. Sometimes I get lucky and can use my device just fine for a few hours, then apps will crash and stuck back in bootloop.
I have factory reset in recovery, and also flashed latest stock rom via odin, I am new to this and this was my first time I might add, it passed but it hasn't resolved the issue, is there anymore steps with odin or anything else I can do to repair this? The device isn't rooted if that helps.
I think that's a motherboard issue
You could try installing a custom rom
