Help, out of ideas. Possible mother/logic board going bad? - Sprint Galaxy S 5 Q&A, Help & Troubleshooting

I have a well and heavily used Galaxy S5 (GM-900P) and about 2 months ago it started accting up pretty hard. Becoming very very slow so I decided to update to the latest sprint firmware and install a new(er) rom ([ROM][QD1][6.0.1]14Dec2017] Stock-ish Plus Tidbits and Magisk) and all was good for about 5 days and the phone started having apps crash/force close like crazy and most the time just reinstalling them would fix it but a bunch of google play services would crash and would have to uninstall the updates then it would work again for a day or so, sometimes it would randomly restart and get stuck at the boot screen and the phone would get crazy hot and the only way out of it was to boot into the recovery and then reflash the stock firmware in odin again then reinstall the rom. Then I had my phone all of a sudden act like there was no sim card in it and originally though it was a sim card issue but turns out it wasnt, I had to boot into the recovery and do a full wipe of everything reflash the stock firmware yet again and then reinstall the rom again. That happened twice in a matter of a week. At my wits end I decided to give LineageOS v16 a try so I boot into recovery, do a full wipe, boot into download mode, flash the latest stock firmware in odin, then boot right to recovery, flash LineageOS 16.0 then latest Magisk and all was great, for about a week, then Google services start crashing again and random apps crash over and over and even times the phone would slow down and reboot, get stuck at the boot screen and then eventually just reboot back into recovery by itself after failing to boot. But with LineageOS at least just reflashing the rom in the recovery will let it boot right back up sometimes and work as it should for another few days, other times too much stuff will just keep crashing so I do a full wipe and reflash LineageOS and all will be great for another few days to a week and it starts all over again. Its like stuff just randomly gets corrupted on the device and the only way out of it is to reflash the whole thing and start over and enjoy it until it does it again. Sometimes it will go days, sometimes a day later its all screwy again.
Also, TWRP always fails when I try to do a back up and it seems to always fail when in the data or data/private-app part of the system and its never at the same point.
I guess my question here is, could the onboard flash (the motherboard/logic board) be taking a crap on me? I really really dont want to give up on this phone just yet as it has everything I want in a phone and frankly, I just really really like it. I can get a new (used) motherboard for like $20 but even that kind of worries me cause I dont want to possibly be in this same position 3 months later again. I have a Galaxy S8+ (unlocked AT&T phone) that I refuse to use yet just cause I can not root it or unlock the bootloader.
Any help or ideas would be much appreciated and sorry for the long winded post.

could be wrong, on this one, But.....
If it was mew, I would go to stock . run that for a day, maybe 3... if all it well, then flash over what ever Rom you would like.
"KNOWING IT Work" is the key. Oh, another thing, that may help too . seen this on one of the LineageOS 15.1 or 16 is when you wipe ... System and Data, can be Reformatted, they have had some major success by also formatting it, (YES EXT4) but this will help to ensure nothing left over....
May even help with others Android 8.0, 8.1, 9.0....

Well, I have a new motherboard on the way so we'll see how that goes but I did manage to get the stock firmware on there and booted then I reflashed TWRP and then Magisk and going to just run it that way for a bit and see what happens.
I initially went in to TWRP, wiped data,system, etc... then flashed the stock firmware in Odin, then rebooted, got stuck at the Samsung boot logo so pulled the battery, booted to stock recovery, did a factory reset (Wiped everything, internal sd card included), then got it to boot, set the phone up, then rebooted to download mode, flashed TWRP, then rebooted again, set the phone up a bit more then decided to flash Magisk so I have root, and so far its working. 100% stock with magisk. Fingers crossed.
I still think there is an issue with the internal flash memory though as I can not get a TWRP backup to actually complete without failing. It always fails when backing up stuff in the data partition/section and never at the same point like its having read errors or something. I'll grab a TWRP log and post it up in a bit.

Well, that didnt last long. Within an hour, apps started crashing. I will make this thing work! LoL

[Q] Phone never boots after flashing new ROM

Hi!
I am currently running CM12-20150314-NIGHTLY. I am still using this old version because every time i flash a new rom the phone won't boot. It will ALWAYS get stuck on the splash screen. It will still be possible to access recovery mode, but it won't help wiping, reflashing the new version or reflashing the old version. To solve the problem i have to re run the guide for "root, ulocking bootloader and flashing recovery" to get the phone to boot again.
Do someone have an idea why the phone won't boot after upgrading to a newer rom? I have performed the process three times with different versions of the rom so i know it will happen if i flash a new rom again.

Bump
Couple of questions. What roms are you trying to flash and where are you getting them? How long do you let it sit at the splash screen before giving up? When you say wipe, do you mean a complete data wipe? Or just a cache wipe? My thought is that it could be any of the following:
1. You just need to let it sit longer. The first boot after a new flash can take a really long time.
2. The rom may not be complete, or it could have been a bad download.
3. You aren't wiping everything and there is something conflicting.
If it's not any of those, let us know. But we need more details.
Thanks for your response!
This time i have not tried to flash a new rom, since it have not worked the past three times. Last time i think i came from CM12 20150210 to about 20150215. But that did not work, neither the previous flash between to ROMS.
1. I have let the phone load for at least 20 minutes one time, shouldn't that be enough?
2. No, really don't think that's the case, since i can't even get the phone to bot with the rom that i was previously using.
3. i have tried to wipe cache and a complete wipe, no difference
/diddi
It seems like you know what you are doing. For good measure, I would try instead of installing a nightly, just do a nandroid backup, and try a completely different rom designed for the the OPO. If that won't flash, then it may be something wrong with the recovery or bootloader.
Thank you! Will try that tomorrow when i got some spare time! I'll come back with the results!

Note 4 Edge is in a boot loop

So it has been quite some time since I've been on these forums or tinkered with any phones. I believe the last one I rooted was a Thunderbolt.
Anyways, I have recently tried to root my Note 4 Edge and I hate to say it but I got cocky and rushed through it and now I am in trouble. (I know -- stupid)
I followed this guide (http://forum.xda-developers.com/note-edge/general/easy-steps-stock-odin-n915tuvu1anjl-sm-t2943993) and everything was working right, followed the steps and what not. Unfortunately I did not create a backup of my last known working boot (Again, stupid, I know.) Needless to say, when I went to boot my phone up it was in a boot-loop. So I tried a wipe of everything using TWRP, everything except Micro SD and internal storage. Tried it again after the wipe, I get an message from TWRP saying that I have no OS (oh, great to see after flashing a rom).
After messing with that for an hour or two just to try and get my phone "working" again I gave up on it and tried using a ROM called HyperDrive, I think it's called. Wiped everything needed before flashing the rom, installation went smoothly, no "NO OS" message from TWRP. Rebooted phone, and what do you know, another boot loop.
Its been a while since I've tried tinkering with my phone, if anyone knows of what I did wrong or knows how to fix it I would greatly appreciate it considering ill need my phone for work tomorrow.
Please, and thank you.
Of course you wiped the system so no OS, i suggest you flash the stock rom via Odin first.

Stuck in a bootloop + CWM question

Edit: Solved, see bottom
ROM (D6633_Customized HK_1290-5630_23.4.A.0.546_R6C_HK_SuperSU2.46_XZDR2.8.21-signedv2)
Bit of a dumb move on my part. It all started when my snapchat stopped working, I updated, and then Titanium Backup wouldn't restore the data properly (giving me "parse error"). I was trying to fix that and read online that sometimes this is caused by improper permissions, so I booted into recovery mode, couldn't find the option, but somehow decided "hey, maybe my root permission (?) is wrong slash it's 6am and I just watched a wild 2016 election end" and I hit the button. Now my phone is stuck in a bootloop.
So my question:
1) What exactly does re-root phone do (in CWM), and why would that have messed me up? Is it because I have a pre-rooted rom?
2) I wiped cache and delvik and it doesn't help
3) How do I fix this? I was thinking of loading a SuperSU zip on the SD card from my computer and flashing that, assuming somehow a corrupted root is at fault. I can't seem to get the thing in ADB mode as a side note.
3b) If that seems like a good idea, does it matter what one I use?
4) If I reflash the ROM, it should keep my apps and stuff, ya? I don't actually care if my phone is crippled, I just need it to work long enough to properly back up some media, and mainly get my whatsapp over to my new SIM card. If I can't get in it's forever stuck on my old number which I don't have the SIM for anymore.
Any help would be GREATLY appreciated.
Edit: I don't know how to delete this. Anyways, with other resources I found out that because I used a pre-rooted ROM, there were issues with using CWM to try to do the rooting with its built in functions, softbricking the phone. Reflashing the original pre-rooted ROM worked fine.

My phone randomly died? (Soft brick, not a hardware failure)

So I have an XT1031 and it's been running Ressurection Remix MM (Thuglife kernel) for about a year now when suddenly it died today.
I haven't messed with anything, simply uninstalled some apps, mainly games then a few hours later it all the sudden rebooted, now when it boots up it'll optimize apps and once it has finished it will crash or something basically causing it to bootloop. Why?
Thankfully anything really important, such as pictures, are already backed up to dropbox, so I haven't lost very much but is there anyway to salvage it?
(Note: I have booted into recovery and tried deleting both the cache as well as the Dalvik/ART cache no good, unfortunately...)
And... While I'm here I figure I might as well ask how to install Nougat? By that I mean, can I go straight from MM into Nougat or do I need any sort of updates first?
Thanks.
Alright, since nobody apparently has any ideas on the matter, I went ahead and factory wiped my phone and it works now, although I'll probably wipe it and install a Nougat rom later.

oneplus6 seems damaged following a failed twrp restore

So here is situation.
Phone been running 8.x version of havocos for months, however I was never fully happy due to broken usb tethering and random lockups (blue light freeze).
I decided to work on the phone 2-3 days ago, this involved doing a manual backup of all of data/media, and a nandroid backup. As well as some exports of configs in tasker etc.
I then flashed OOS stock, and nolimits, discovered tethering was still broken (yet it works with same sim in samsung galaxy s7 and hauwei).
This was the only issue tho, everything else was functioning as expected, phone was still fast.
Then I needed quick access to something that was on my phone from havocos, so decided to do a nandroid restore, this nandroid backup had all partitions ticked. The restore I also had all ticked.
The restore failed with an error 255 during data restore, I googled and found out is a nasty known bug for 2 years on TWRP, this backup was done on 3.2.3, I know now is a newer 3.3.x where this particular bug with corrupt backups might possibly be fixed.
I decided to try and boot havoc anyway but it boot looped, so I then went back into TWRP, and restored the vendor partition which was skipped. As it stopped on data, still boot looped, but also now this created a device is corrupt error on every rom boot even on stock OOS.
I spent ages trying to fix this error and during the process, discovered my phone no longer can be detected in flash boot as a com device in windows so currently the phone cannot be used with the MSM tool.
Eventually I reflashed stock using a flash-all script from here, and also put back on twrp using that script, and noticed even more issues that were not there before.
1 - phone is now much slower, stock before booted in one second after first boot, now its way way slower. Over 10 seconds so 10x as slow.
2 - I think before was a cache partition but is now gone. Supposedly these arent a thing anymore tho.
3 - nolimits zip will no longer flash with an error 1, I did exact same process as before but simply doesnt work now, the twrp detailed log right before the error 1 says "Please install the latest Magisk!" which suggests its failing to detect magisk.
4 - camera app is way slower, and OOS feels slower, laggier in general than before the problem.
5 - MTP no longer works when phone is booted up, again this is stock OOS and even if phone isnt rooted no magisk etc. But still works in TWRP. Basically the device pops up, I can see internal storage, but the size information is missing, and is no visible files/folders.
From what I can see I think my EFS is fine, I see an imei number.
I did fix the corrupted device error using a reboot command someone posted in that thread, so that error is gone now at least.
Try to flash oxygen os beta version from the official download links, let it install the stock recovery, then boot into rom, finish the installation progress by just skipping it and then factory reset it twice from recovery mode.
after doing that and finishing the setup , try to take picture and see if its saves it to gallery ( if the picture delete it self try to factory reset it through recovery for 1 more time)
I think you have figured out whats wrong, it just clicked, and I went to post and found your post so sorry no reply yet.
Indeed the problem seems to be a lack of /data/media/0
I have multiple times wiped data, and twrp has been putting files directly in /data/media, I just discovered I Cannot even take screenshots, magisk cannot download modules as well.
So I guess the stock recovery creates this structure?
Pretty shocking that twrp doesnt fix this or even have an option to. I will report back and let you know how things go, thanks.
Issue still there after stock recovery reset, wow these phones are damn hard to work with.
Also it seemed to do nothing, no settings were lost etc.
So basically stock recovery even if I choose full wipe does nothing, there seems to be some kind of lock on the internal storage that anything made by one plus is refusing to write.
I wonder if this is due to the device is corrupt message I had before where it said the device can no longer be trusted.
I can confirm that files that are on there are now visible in file manager and root explorer. But file manager can do no writes. root explorer can create new stuff but cannot delete or overwrite anything there, gets access denied.
I propose to start over again following this guide, option flash-all-partitions.bat. Helped for me.
I already stated thats already been done.
I eventually got msm working. and that luckily worked.
@chrcol ..., but you've issues

In recovery, format data. Problem fixed. Wipe will never fix your problem but format will.
