Dear XDA Community,
since 4 years iam using a Samsung Galaxy Note8 SM-N950F. It works comepletly fine until one day the device suddenly reboots by using it.
At first i wanna mention, that the Hardware didnt got conact with water and at this day and the days before it didnt fall down.
At the first reboots I always got to the home screen and could use it for a few seconds. But after a few reboots its get stucked by the logo.
After 5 hours of rebooting, the device worked like before... but only for one day. The next day its beguns rebooting again...
I try to break the loop and opened the bootmenu. From the bootmenu the device did not reboot but display the following message (Picture-1):
firmware info was not valid
Then i wiped and restartet it. I clicked through the firststart dialog after i reach the home screen and then i joined the reboot loop again.
I tooked my phone to a repair center but they said it will be a mainboard defect which i cant belive cause it dont reboot from the boot menu and from the android download mode...
The resettet and said they installed a new firmware but the error message didnt changed.
I also followed this guide to do it by my own:

firmware issue Samsung Galaxy S8 (SM-G950FD)
Hi, I have a serious issue with my Samsung Galaxy S8, 64 GB, dual sim. My phone has stock android, never rooted, never modified in any way. I run it in Australia but got it from overseas. After a system update (sometime in December) my phone rebooted (precisely on 29/12/2019), and after the...

If this really a hardware defect? Or is there anyway to rescue the phone?

Phone Condition: Very very new (Less than 48 hours)
Problem Description: The screen freezes randomly, restarts randomly, sometimes the screen freezes without restarting and can be stuck there forever
Solution tried:
(1) Wiped cache partition through stock recovery as suggested by everyone on the internet (It makes things smoother a bit but it still has the problem)
(2) Wipe everything and reset the device (Problem still persists)
(3) Flashed the latest available stock firmware with ODIN (Link: http://www.sammobile.com/firmwares/database/SM-N9208/XME/ --> Malaysian firmware) (Problem still persists)
(4) Used Smart Switch's Emergency Software and Recovery and Initialization (Problem still persists)
(5) Went to Samsung service center and sent in for repair, the person told me it has been fixed without providing further explanation and details (Problem still persists)
I've spent almost 10 hours troubleshooting and it's driving me crazy, someone please help me.
The whole internet with different blogs and articles only mention the wipe cache partition fix and it's useless.
Sounds like you've got a faulty device, my friend. Try bringing it back to your carrier and recreating the issue. They should replace it for you.

I've bring it back to the carrier and also Samsung today, both of them says they cannot refund me.
Samsung agreed to fix the phone if it's a software problem and if it's a hardware problem they will replace it with a new phone.

How to install it mainly,because i reverted it back to stock a couple times,and i could really use help in installing

Sometimes it helps to reset to factorysettings. That helped me to come out of being stuck at starting.
Hey all,
Looking for some assistance here. I apologize in advance for not having specifics on everything, but it's been a couple years since I've needed to do anything with this phone (SM-G900A). I picked it up used a couple years ago and shortly after, I did a NOX unlock and rooted the phone for two reasons - using Titanium Backup and to unlock the WiFi hot spot. I recently noticed that something had happened and my root access wasn't working correctly- guessing from one of the OTA updates that was attempting to occur on my phone. I say attempt, because I don't believe they ever successfully installed since they always seemed to error out. I'm currently on StraightTalk, not an AT&T customer. Something weird was up with it though, because I could never uninstall the Xposed Framework or app, yet Pokémon Go was recognizing it was rooted and blocking my access. I should also mention that I had towelroot running on the phone and it's showing the custom unlocked padlock on startup.
Fast forward to last night- I wanted to return it back to the stock ROM so I did my research, found a couple different tutorials that included the correct ROMs and applied one - G900AUCU1ANCE_G900AATT1ANCE_ATT.zip. After flashing, the phone will not boot and freezes halfway through the swirls around the Samsung logo, then goes blank. The blue notification light also stays lit on the phone.
Thinking it was most likely bootloader related, I found another ROM that included separate AP, BL, CSC files. I attempted to flash the bootloader, which failed and I got the following error on the phone - SW REV CHECK FAIL : [aboot]Fused 2 > Binary 1
At any rate, it seems like my boot loader somehow got corrupted or isn't compatible with this ROM, but I was hoping some of you experts out there could provide some answers. At this point my phone is dead, so I'm hoping I can get it restored very soon.
Thanks in advance guys!
The issue identified in this thread (http://forum.xda-developers.com/galaxy-s5/help/g900a-stuck-samsung-logo-black-screen-d-t3050369) seems very similar to mine as well as what's described on this website- http://www.galaxys5update.com/fix-black-screen-with-pulsating-blue-led-on-galaxy-s5-g900a/
I'm seeing the pulsing blue light as well. How do I find the 4.4.4 OA1 Kernel identified in the first link?
Hello XDA, I'm having a problem with my grandmother's phone, and I'm in a hurry to get this fixed because she needs it for business. Her phone is an AT&T Galaxy Note 3 SM-N900A unlocked to T-Mobile. It was running Android 4.4.2 KitKat, and I tried to update the phone as I did with my grandpa's, who has the same exact phone before we switched to T-Mobile. Because it was unlocked, the phone couldn't receive the OTA Lollipop update due to the SIM card not being AT&T.
After spending 4 hours searching and trying solutions, I came down to one thread on XDA Forums here. I saw it and I ended up using Odin 3.09 to flash the All-In-one/Non-Wipe Tar file onto it, now my phone is stuck in a boot-loop. Strangely, the Lollipop update seems to be installed as when I plug her phone into my PC/charge it, the battery screen is different than the old one which looked shiny and not flat and material like the Lollipop one. Knox has not been tripped, system status is OFFICIAL, and every time I turn on the phone, it proceeds to boot until the AT&T logo screen, where it freezes mid-way vibrates 2 times and boots the same way over and over again.
Is there anything I can do aside from doing a wipe or factory reset, as I mentioned before she has to use the phone for a business she works for and she had somewhat important work on the phone. The worst part of it all is I was stupid and ignored the warning to back my data up first in the firmware thread. Please help, I'm in a very big hurry to solve this and finish the updating/problem.
P.S If it's not a boot loop and it's called something else, whatever. xD
Did you try using Smartswitch to see if it can see and repair and/or reflash? A factory reset may be the only way to fix it because I believe the file layout for KK and LP and different.
Hello,
I received a at&t galaxy s6 edge, it was rooted and kept popping up knox warnings, so I looked at the baseband version and it was G925AUCU6EQCF, I googled that + stock rom which lead me to this thread.. which I downloaded and flashed using Odin, afterwards my touchkeys/softkeys just no longer work. They were working before flashing.
I've tried, wipe cache, factory reset, safe mode booting, *#2663# -> sensorhub fw update is grayed out, I also tried multiple new charging ports.
Little background, I don't know much about rooting and android roms, but I run a repair shop and do bunch of hardware repairs. I recently received a dozen or so assorted s6, s5, s6 edge, note3, note5 which all appeared to have been throwing KNOX warnings (among other issues, broken screens, charge ports, etc..). Now I'm not completely oblivious to this stuff, but I've flashed stock roms and installed twrp +root before on samsungs. For 10 of the phones I googled the baseband +stock rom and was able to flash it back to stock and KNOX warnings went away and all were fully functional, not sure If I'm doing it right but it works, perhaps unrooting would have been easier/quicker?
I opened up the phone and tried a working charging port from another s6 edge which I know the softkeys work, but I still got no touch on them, they only light up but no function or vibrate, so I did some googling and noticed I may not be the only one. I've seen some threads here but for other samsung phones, some mention something about "flash some idlekernel that will update the touchkey's FW", another mention build.prop and other "qemu.hw.mainkeys=".
Now, I am not all too technical with this so I was hoping some handsome generous person could help me out or point me somewhere, anywhere
Thanks!
