HW related bootloop? s7edge G-SM935FD - Samsung Galaxy S7 Edge Questions and Answers

OKay long story if you're interested in details, this is different to the other bootloop issues, I think this is HW related.
1- Phone suddenly started getting into booting loops. Phone never rooted nor flashed with customer ROMS..
2- Strangely this happened after an official update from Samsung.
3- Booting in recovery mode, wiping cashe and rebooting helped and the phone worked but only for a month or so until it started getting into the loop again.
4- This time it's more stubborn, it doesn't even allow me into recovery mode, it reboots before I can do anything.
5- once every 50+ times it would allow me into recovery mode, I tried wiping cache and factory reset but they didn't help, phone always restart after the samsung logo appears.
6- I thought this is the time I try flashing a custom ROM and see since it was on Stock ROM, but unfortunately realized I had OEM disabled and hence FAP ON and can't flash custom ROMS (or can I?).
7- I thought to flash stock ROM again using Odin. I did so, nothing different, still getting the same issue and now even worse, it would sometimes just give a black screen with flashing blue light.
8- something weird regarding the Stock ROM, my devise is G-SM935FD, however, the latest official update samsung installed on my device changed it to G-SM395F, I know they are mostly the same but trying to use the latest ROM from Sammobile for SM935FD wouldn't work. only the one for SM935F is accepted by download mode. Probably it's because I bought the phone from Dubai (395FD) but then moved to Portugal, so it started sending me the updates related to Europe.
Now at the moment, the phone can't load beyond the samsung logo. It can occasionally get into recovery mode. The only stable mode is download mode but I can't flash any customer rom or twrp because of FAP ON.. so I can only flash stock ROMs which didn't change anything. Does anyone know a way out of that? maybe a ROM that can bypass the FAP ON and uses less processing to load. I know I'm probably asking for something magical and I would most probably not get any answers over here.
I have no warranty and the phone is in a horrible condition so I am not sure if taking it to Samsung would be useful at all.

[Q] GT-i9500 has no OS installed.

Hi everyone I just recently purchased a used S4 the GT-i9500. Everything seemed fine until I got home. It detected my T-Mobile Sim fine but I could only access 2G data and could not connect to any WiFi network I came across. The rom was stock 4.2.2 and the phone was rooted pre purchase. So after fiddling around for a few minutes I discovered the previous owner had flashed TWRP v2.4.1.0 as his choice for a Custom Recovery. Now at this point I had decided to flash on a Custom Rom and of course I first made a backup before flashing on WanamLite. Now after attempting to flash it I immediately received a failure. I tried turning off the signature verification and it did not flash. Now in my frustration i attempted to wipe everything and tried flashing Omega Rom v14. Now i was able to go through with the installation and choose what I wished to install and when I pressed Install things went along smoothly until I hit the app SecSafetyAssurance.apk where it freezes. This is a bump that I've run into at least 5 times already. I changed certain options I wanted to install and eventually made it past this and I am prompted to reboot. Now when I do this to my dismay I just receive a black screen. Upon pulling out the battery and attempting to reboot I still receive a black screen. when I boot back into the Recovery and attempt to reboot the system from within TWRP it warns me saying No OS Installed Are you sure you want to reboot. Im at a loss of what to do. I have read about other members suggesting to use ODIN but I am very confused about how to access Download Mode in order to flash a stock rom from SamMobile.com. I could use a few tips or maybe a few options that I'm left with in order to obtain the operation of my phone again. I would like to get my phone back and Im sure some users can relate to how Im feeling so any help at all would be greatly appreciated. Thank you very much in advanced!

Flashing through odin is one option.... some users have reported that there were some hiccups when installing omega 14 because of the aroma script.....try a different rom...there are many others to choose from....or you could flash stock via odin as said on the earlier comment good luck
Feedback
Today I attempted to use ODIN to flash now I am still currently attempting this. When I press the volume down key, power, and home button it takes me to the custom recovery TWRP instead of download mode. The phone did this when I first purchased it. When I still had what appeared to be the stock rom it would always take me to the recovery. When I would use the volume up instead of down it would take me to the factory test mode now mind you this happened when the OS was still installed. When i try that combination now i just receive a blank black screen. Are there any other ways to boot into download mode?

[SM-T530] Screen "frozen" after flashing stock 5.0 Lolipop

So I've been having this strange issue for a year now, where I want to upgrade my SM-T530 (Tab4 10.1 wifi) to the stock Lolipop (5.0.whatever) ROM in order to get the damn kernel updated so I can access all these wonderful custom ROMs (Stuck on CM 12 atm...).
But whenever I flash a stock ROM for my model, it seems to freeze the screen after the boatloader. As in, everything seems to be working, sound and touchscreen, it just doesn't update/refresh the screen. Basically, the same behaviour as described in this post.
So here's the steps I took, in the hope that anyone can point me in the right direction:
Boot tablet in recovery (TWRP 3.0.1, in this case) and wipe Dalvik, /data, /cache, /system, basically everything)
Reboot tablet into bootloader/download mode
Using Odin 3.11.1, flash T530XXU1BOL2_T530PHN1BOE1_HOME.tar.md5 (Found here, which should be the correct ROM for my model (Bought in the Netherlands, but I have no idea where you folks are pulling this T530XX stuff from, it's nowhere to be found on the back))
Reboot tablet
After the 4th step, the tablet will be unresponsive for ~10 minutes (I think it's doing the whole "upgrading apps" thing that follows a new installation). After that, when I hit a certain area of the screen, I can hear the regular Android touchresponse, raising the volume also give the normal beeps and pushing the power button plays the "turning off screen" sound, but the screen stays active, showing the Samsung Galaxy Tab4 boot logo.
Soooo... Anyone care to take a guess what I'm doing wrong?
Personally, I think it might have to do with flashing the incorrect stock ROM, but for the life of me, I can't find out which T530-code I have. I've been flashing different ROMs, but no luck so far...
As for troubleshooting I've already tried:
The above procedure, afterwards flashed TWRP via Odin and flashed a custom ROM via TWRP. Same effect.
Variations of the above procedure, where I keep wiping the tablet after each step
Different custom ROMs
Ugh, nevermind.
Turns out I have an UK tablet (BTU-T530XXU1BOG2). After flashing a dozen or so ROMs, this one did the trick.
Oh well, problem solved :good:

N910F problems - emmc read fail/ flashing stock no longer boots the phone.

Hello. I had gotten this Note 4 phone which had a custom recovery installed on it but the rom seemed to be official, on 5.1
The first thing I did was go to samfirmware and flash a 6.0.1 rom, it went fine, phone was working properly. Then I got greedy and wanted to test a Note 7 ported rom. Flashed TWRP recovery and from within I flashed RamROM http://forum.xda-developers.com/note-4/snapdragon-dev/rom-sm-n910g-ramrom-t3400349 , I downloaded the one from post#2 , the N910F one that my phone is and after it flashed to ROM it simply stopped working. My phone no longer booted, was booting me directly into Download mode with emmc read error. I kept trying to flash the stock rom which I previously flashed and it would fail.
Afterwords I used Smart Switch to reinitialize the phone, writing my phones S/N and that failed as well but at least that made my phone boot into a different recovery where it said to connect to Kies. Once again I used Smart Switch and this time it was successful 100%. My phone even booted into the OS and was working, however, while using it, after 10 minutes the phone restarted into Download mode with emmc read error.
So all in all the phone is functional but it starts to lag and restart. Now I'm kinda stuck again since I've tried to flash the firmware I got from Samfirmware through Odin, it succeded but it just doesn't boot, it goes to Recovery, tries to apply an update and I get an error.
Is there anything I can do? I can't believe the emmc could've broken just from trying to flash that custom rom, especially that afterwards I was even able to boot into the phone.
Thanks for reading and I appreciate the help.

read this - http://forum.xda-developers.com/note-4/help/note-4-issues-t3453048
there are links to more threads related to your issue.
Short version though:
it is dying. install wake lock application, add it to start up and set settings to #4.
accept the fact that your phone will eat the battery faster and one day WILL die completely
Thanks for your response. Regarding the Wake lock application, I'm starting to look into it, I asume I'll have to be rooted. I'll try to recover it again using Smart Switch and then I can only hope I can install TWRP and still have it functional.
Previously when I was able to get it working with Smart Switch, entering the recovery messed everything up. It said it was applying an update and that got stuck.

no need to be rooted, just download, install and set it to autostart
I'll try it if I somehow manage to get the phone working again, Smart Switch just fails now midway through.

Is this the app you're talking about? https://play.google.com/store/apps/details?id=eu.thedarken.wl&hl=en
What exactly does it do?
I managed to restore it eventually with Smart Switch, it took quite a few tries, then I switched to my Macbook when I saw the app was available on it too and the 3rd try succeded. I only did it because I saw the 2nd try had the % much higher than the first.

yes, that is the app.
i've read it does not allow your phone to go to sleep mode.
drains the battery faster, but this is the only way to keep note 4 working without swapping its motherboard...
I have a question, my gf recently bought a note 4 and we may swap our phones and if we do, i'll flash CM and tinker with it because i find this phone very interesting, just a question, does this bug affect the N910C (exynos) model? Do i have something to worry about? Because the phone is warrianty protected and if it's the case, i don't want to break it. I hope someone will shed some light on this

S5 reboot issues

Hello, i will try to be as elaborate as I can cause I know you guys here are really knowledgeable when it comes to smartphones. So, here are the issues I am currently experiencing with my G900F phone. Just a background, everything in my phone is stock (rom, recovery, kernel) no changes done yet. It currently runs MM with a security patch of February 2017. As of now, I can't boot into the phone.
1. . I was able to successfully root it with CF auto root.
2. I started experiencing random restarts. I tried obtaining the last kmsg however it does not exist.
3. I tried flashing a new ROM thinking maybe there is some rare bug in the stock rom i currently have. I flashed TWRP via Odin, to be able to flash a new ROM. Odin successfully flashed the recovery however when i proceed to install a new ROM through TWRP the phone gets stuck in a bootloop. I do not experience this in the stock recovery
4. I was able to restore the phone through Smart Switch device intialisation. However, with everything stock I still experience the random reboots.
Bottomline: Is there anyway I can fix this on the software side (e.g. flash/update this or that)? And if not, do you think this is a hardware problem? Worth mentioning it's got a yellow screen bug but if i press hard on the back of the phone it disappears. Also, I can boot into stock recovery and download mode without any problems.
Thanks and sorry for the long post really need your insights.
Sorry you are having issues. I apologize if I missed this, but have you tried downloading the official firmware for your device from sammobile or similar sites, then flash that through Odin?

Soft bricked data recovery

Hey all, been a while since I've been on - longest I've ever had a stock phone for . Hoping somebody can offer some advice as I'm stumped...
NOTE: If possible, I'm trying to avoid a factory reset!
Last night my stock UK Note 4 (SM-N910F) died (possibly during an OTA update but I wasn't using the phone and have been told it didn't so not sure) and when turned back on would just sit at the pulsing Samsung logo with no apparent restarting or anything. Clearing the cache didn't make a difference.
Recovery reported my ROM to be N910FXXS1DQE9 (region BTU). After waiting ages for the download, I first tried BTU-N910FXXU1BOC5 which produced the exact same problem with a different Samsung animation. I then tried BTU-N910FXXU1DQHC which seemed to sort of work - it would now boot but gave me a "Unfortunately, System UI has stopped" error with a black screen. I then flashed BTU-N910FXXU1DQH3 which is what I have running currently but this does the same thing. I did also try wiping cache in combination with the above (is this actually needed after flashing a new ROM?). I have also tried safemode - would let me open the power menu but otherwise did exactly the same thing.
I'm currently downloading the original ROM that wouldn't boot (N910FXXS1DQE9) from samsung-firmware but it's taking ages at ~50KBps. What are the chances of this working compared with the others, I assume probably not much? If likely, I'll pay up for an account and a quick download.
I've also tried flashing TWRP but I have reactivation lock on - does anybody know a way to disable / bypass this without access to the phone (research tells me probably not but there are a lot of smarter people than me here that I hope could tell me otherwise ). I can get into stock recovery but that only gives me ADB in sideload mode and I can also enter download mode fine obviously. Does anyone have any suggestions on recovering data from the phone before I factory reset?
Simply put, have I lost everything on the phone or is there a way I can retrieve some of it?
Also, I do have a load of server space I can offer with decent bandwidth - I have those ROM images above so I can offer these for download at a decent speed without a cost if anybody here on XDA needs - just send me a PM for a link
