So...
Last week, my wife's Tab S went into a bootloop. She runs complete stock, we haven't rooted, or anything. There had been a notification about an update, but she hadn't touched it. She'd updated to Lollipop at some point last year, but hadn't applied the absolute latest update. One day last week, she just turned it on, and it started bootlooping.
Because it was so stock, there were no backups, no nandroids, or anything like that. No Custom Recovery. I told her "well, we can just do a factory reset. You'll lose everything, but once we get you back up and running, it'll just re-download everything from the Goog." So we factory reset it. Looked good for a minute, booted into the first screen, enter in your Wi-Fi password, all that. As soon as we got the Wi-Fi password entered, however, it re-booted. And keep rebooting. Bootloop city. No problem. I walked her through (over the phone) using Odin to flash the latest Lollipop firmware. No dice. It appeared to flash successfully, but still bootlooped.
Over the weekend, I tried using Kies to flash the most official firmware I could find. Everything was successful -computer recognized the device, was able to download "direct from the source," as it were, but it got stuck at 69% twice before failing. I read somewhere that one had to run Kies in administrator mode to get it to successfully complete. So I did, and it got past 69%, successfully completing the flash. STILL NO LUCK. STILL WITH THE BOOTLOOPS.
Last night, I realized that I hadn't flashed in Odin using Administrator Mode. Tried it, using latest 5.0.2 (XAR-Cellular South). Flashed successfully, all appeared well. Still bootlooped.
So, I'm stuck. I can get into recovery, I can get into Download Mode, I can successfully flash. I just can't get the darn thing booted.
Thoughts, anyone? Should I try flashing a Custom ROM? How hard is that using Odin? Thanks in advance.
Ok this will take a few tries but here is my method of dealing with this situation
1) Flash stock using Odin
2) AS SOON AS the screen goes blank, start holding Power+Volume Up+Home
3) When recovery boots, release the buttons
4) Use the volume buttons to select "Wipe data/factory reset"
5) Press power to confirm
6) Reboot
If that doesn't work, you may either:
1) (more likely) Installing a ROM will fix the problem
2) (unlikely but possible) You might have worn NAND pages, which I doubt but could cause this behavior.

Thanks, I'll try these steps tonight when I get home, and report back!
All right, here's something interesting. Before I tried your first step, I remembered that the other night, I left it stuck at the Samsung logo -it was just kind of stuck there, and since the behavior was a little different than I'd seen before (not continuous bootlooping), I thought I'd boot into recovery and wipe. I did, I wiped (factory reset), and rebooted. The tablet booted into the first screen, Accessibility/Wi-Fi, blahblah. This was where it usually rebooted. On a hunch, I bypassed entering in my WiFi key. I then bypassed almost everything else (Samsung account, Google account, etc.), expecting that the tablet would reboot at any moment. But I made it to the front apps page, where it shows you the side-launcher, the Magazine-Flipboard thingie, and whatnot. Wi-Fi still not connected, though. I opened up the app drawer, and scrolled around. Looked really good for a moment. I even took a picture with the camera, and viewed it in Gallery! Feeling brave, I thought, "well, maybe it just needed a couple of minutes before firing up the radio." So I went into settings, and inputted my WiFi key. It connected. And rebooted into its bootloop. (getting so tired of that boot-sound).
Went ahead and flashed the most original stock firmware I could find. As always, flashed successfully. As soon as it booted, I made my way to recovery, and wiped, per your instructions. No luck. Bootloop again.
It's something in the WiFi is what I've come to think as a result of the above. Which I don't entirely understand, as I thought the radio got re-flashed with the firmware.
I'm ready to try flashing a Custom Rom. Can I do that through Odin, or should I try and flash TWRP, and do it through there? Will TWRP flash without a working (bootable) OS?
All right. Thanks for your response!
Try this as a test.
First make a full backup of every partition with twrp including the EFS <<IMPORTANT!
Get it booting again without wifi then root the device and delete the EFS folder or delete it in recovery.
Reboot the device and try and enable wifi.

Got TWRP installed. Won't backup. Fails at 16% (system partition, I think). Just powers down to battery indicator in the middle of the backup. Looks like it backs up the EFS, though, since it's the first one. And when I go into TWRP's Restore option, there's a backup there (though I don't dare try and restore it).
Now I have to figure out a way to get the Custom ROM and GAPPS I downloaded onto the tablet without a reliable boot... It's gotten to the front screen a time or two tonight, but starts looping even when I bypass the WiFi setup.
Entered adb/TWRP interface. Tried to push two files, a Custom ROM file, and a GAPPS file. The ROM failed, with some sort of "Error 7," incompatible data, blahblah... Just out of curiosity, I tried to push the GAPPS file, and that failed after about 6%, and the tablet powered off.
I'm running out of ideas.
copied a custom rom to a USB/OTG stick (thumbdrive), and plugged it in. Fired up TWRP, tried to install. Wouldn't. Wouldn't install GAPPS, either. Looks like the only way it wants to flash anything is through ODIN or KIES.
The Latest...
All right...
I remembered that sometimes the TWRP version mattered. When I installed TRWP last night, I installed the latest and greatest, 3.0.2. Last night after I gave up, I remembered that sometimes, the latest and greatest TWRP doesn't install things perfectly. So, this morning, I downloaded TWRP 2.8.6-ish onto the USB/OTG device, and re-flashed the recovery partition. To be honest, I was surprised that TWRP was even able to flash that (but the TWRP image is only like 9.8 MB, so...)...
Got TWRP 2.8.6.0 flashed, and rebooted into TWRP. Immediately decided to try and re-flash the custom ROM that I'd tried unsuccessfully to flash last night, since the thumbdrive was still plugged in. Resurrection Remix Lollipop. Lined up GAPPS in the queue, as well. The ROM *appeared* to flash better than it had in TWRP 3.0.2, but it was sort of hard to see... GAPPS failed, and I was prepared to watch another round of bootloops. It did bootloop, sort of. The RR splash screen appeared, said that it was installing (or preparing) xx out of XX apps. Then, it rebooted. I figured it was doing its bootloop thing. However, it got to the same screen, "installing xx out of XX apps. Except that XX number had gone down, and the xx number had gone up. It repeated this action about 4 times --the last time I saw it reboot, it was "installing 1 out of 2 apps." And then...?
It booted into the RR lockscreen.
Of course, there were no GAPPS. In fact, there are something like only 20 apps total on the tablet. But it appears somewhat stable at the moment. (See picture).
Afraid to try and connect WiFi, afraid that it'll just bootloop.
Speaking of bootloop. At one point, once we got it booted, my wife hit an option in the Settings. LCD Density, I believe. As soon as she hit it (she literally just placed her finger over the 320 default option), the tablet rebooted. No loop, though. Rebooted straight back to the RR lockscreen.
So I appear to have a somewhat stable OS flashed onto the tablet at the moment. No GAPPS, though. No WiFi.
Anybody have a suggestion on where to go from here? I have my doubts as to whether or not I can even back up this configuration.
Sorry about all the updates. I kind of figured that if *anyone* else ever goes through what I'm going through, they'll have some sense of all the different things that can be tried in resurrecting a bricked/bootlooping device. I appreciate everyone's efforts to date -thank you so much, @Lightn1ng and @ashyx.
All right, because I can't leave well enough alone....
I got WiFi up and working. Tablet still stable and working. Wheeeee.... No GAPPS, though.
Downloaded GAPPS, second-smallest package from opengapps- only 128M (5.1 ARM package). Downloaded it in Android, from the tablet! Tried to flash it in TWRP. Failed, tablet rebooted halfway (not even) through. Now it's bootlooping again...
I should've left well enough alone, and waited for someone. Have tried re-installing Resurrection Remix, but tablet keeps failing to flash. Might have to try and flash a different TWRP. I don't know...
Have you tried another Gapps? Also, is this the WiFi only model or the LTE model we're talking about?

It's the WiFi-only model - SM-T800.
It's kind of weird. I thought it might be some sort of internal memory problem (like the worn Nand pages you mentioned), since almost anything I try to do in TWRP fails (although I was able to flash an entire Custom ROM the one time AND get it booted) -but backing up isn't working, whether it's to internal/external SD. And the fact that I can flash perfectly (subjective term there) well using Odin or Kies tells me that whatever problems the tablet is having, something's getting through.
I'll try a different GAPPS package. Right now, though, TWRP isn't letting me flash hardly anything, and moving files back and forth on this thing is just awful.
AGH - I was so close!

Maybe somebody else with a T800 could backup their entire EMMC using
Code:
dd if=/dev/mmcblk0 of=/sdcard/full_nand_dump.bin
And you take the file on your tablet and do
Code:
dd if=/sdcard/full_nand_dump.bin of=/dev/mmcblk0
And restore YOUR efs folder using TWRP.
THIS IS A DANGEROUS OPERATION AND I AM NOT RESPONSIBLE FOR ANYTHING THAT GOES WRONG!

@ashyx Any more ideas before I go ahead with my evil world domination plan to recover this device?
I wouldnt carry out any risky operations until a full backup can be made with twrp or you may end up with an unrecoverable device.
If twrp cannot backup the system partition then there is an issue with the partition.
Try backup again and post the recovery log, it may contain some relative information.
I have the same issues and have tried eveything. I was rooted and running the latest Pheonix rom on my sm-t800. Last Wednesday (8-10) I starting getting boot loops out of nowhere, no new apps nothing just a daily driver. I've been through everything on here and have gone back to bone stock but to no avail, the boot loops just keep coming. I can connect to wifi and get things set up but if I try to use anything more than 'light usage' the tab starts its boot loops again and rows fits for about 10 minutes and always different timing on the boot. Sometimes it will make it to the Samsung logo, sometime only to Tab S and sometimes about 10 seconds of usage.. I know this isn't helping much but wanted to let you know there are more of us with the same problem. Will be blab to try anything to help said issue.
Exactly the same issue on my LTE version.
Samsung support just asked me 230€ for a new motherboard.
I refused to repair. I think it is related to nand memory..
Hello I have both the 8.4" and 10.5" I updated the 8.4" to Android 5.02 nothing but boot loops my other is still on 442 and I wont be updating it as its working fine. I have been reading a few posts and the problem was right in front of me all the time I have 2 internet connections 2.4 GHZ and 5.0 GHZ if I connect to the 5.0 GHZ I get boot loops but if I stay on 2.4 GHZ no problems what so ever so I may just install a custom rom and my 10.5 tab and stay clear of the faster internet.

Hello,
and the rest of story??
i can flash TWRP in download mode, and i can intall zip by TWRP , the lineage rom,
but, cant odin flash official md5 file, it stucks on logo.
Like so many others, my phone spontaneously developed the infamous bootloop problem. I've had the phone for less than a year, so Sprint will replace the phone for free, but I have a lot of things stored on internal memory of the device that I would very much like to retrieve before the exchange.
I've tried freezing it and heating it--both techniques succeeded in getting the phone to boot up, but not long enough to do anything other than confirm that all my data is still there.
I've been searching the web and this forum and found the guides about disabling big cores, but it seems that the files do not apply to my version of the phone, the LS991. Other guides describe booting the phone into recovery mode or fastboot/download mode, both of which I've done successfully, but I haven't been able to find out what to do from there. ADB only seems to recognize the phone is there when it's in "sideload mode."
Yes, I rooted my phone shortly after I got it, but I don't have any custom recovery installed because at the time, and apparently still, there aren't any available for this model!
So here I am with a phone that has my data on it but won't boot, and all the solutions beyond extreme temperature and hope are unavailable for this version.
Am I missing something? Is there a reason that a chunk of the population facing this growing problem have been left without the means of doing anything about it? Has someone produced the tools (either a custom recovery or a big cores disabling file) and I just can't find them anywhere?
Again, I'm not the first to ask, but I'm asking anyway. If anyone knows something that would help, please speak up!
I've also posted this on Reddit and the OnePlus forums, but I'm hoping I can find an answer here, too.
Long story short: I really messed up my phone and I'm looking for help getting it to at least boot into the system. Lots of weird, confusing things have happened within the past few days, so bear with me; might be a long story, but I'll try to give you the abridged version.
I run locked and unrooted. I flashed OOS Beta 3 over 4.7.6 on my 5T, wiped my cache, and everything was wonderful for a week. Then one day, I got a system message saying "Bluetooth has stopped". I cleared that and thought nothing of it, but I got another message saying "Bluetooth keeps stopping". This message would actually pop up (with no exaggeration) every second. I could only stop the messages completely after going to the Bluetooth app and clearing the data, then disabling Bluetooth Scanning.
I figured the problem would fix itself, but the next day when I tried to connect to my car via Bluetooth, my phone would freak out again like the previous day. I had to listen to a CD like it was 1996. I thought I could fix the problem with a Factory Reset. As soon as I hit the Welcome screen, "Bluetooth has stopped". When I went to check the Storage section of the Bluetooth app in the Applications list, the app portion read 0 bytes. What? Even when I went into Settings --> Bluetooth and tried to turn it on, nothing would happen. I thought maybe I should revert back to 4.7.4 and start from the very beginning.
That served no purpose. The Bluetooth symbol did show temporarily in the Status bar as I was setting up my phone, but eventually disappeared, with the Bluetooth app once again taking up a whopping 0 bytes. I've done various combinations of installs, but I cannot get Bluetooth to function normally. And at some point, my phone developed a new problem: any time I hit the Bluetooth button in Quick Settings, the phone would eventually reboot on its own. Later, it wouldn't need any input from me at all. It would just be sitting in the Lock screen and reboot.
Icing on the cake: I got desperate, unlocked the bootloader, deleted the system and cache partition in fastboot, then wiped the data in Recovery with the hope that doing a completely fresh install would fix the problem, but at some point my internal storage got wiped and now I have no ROM on my phone to install. Even better: I'm having some real problems trying to install OOS (any version) on my phone via ADB sideload. I keep getting the message "cannot read <filename.zip>", even though it's in the correct folder.
I am currently back on my OnePlus 3 and the proud owner of a very sleek brick. I used to root and unlock Nexus devices and Moto X's, so I'm pretty embarrassed that I managed to ruin my phone while it was running (basically) all stock. It can still boot into Bootloader and stock Recovery. Is there anything at all that I can do to at least load OOS (or any ROM)? Do I have to send it back to OnePlus and beg for a replacement? Will they even take this phone in it's current state? Am I just SOL?
I've run out of ideas and patience. I'm really hoping someone out there can help me. At the very least, thanks for reading my long sob story. Hopefully this never happens to you.
try flash orero based twrp and flahs stock 5.0.3 zip in twrp, see if it works. then figure out the reset.
Why would you delete system from fastboot? Does people not formating partition from recovery more often？
The twrp I use
https://forum.xda-developers.com/oneplus-5t/development/recovery-twrp-3-2-1-0-oreo-8-0-8-1-t3729673
Update: I managed to unbrick my phone using an unbrick tool. The process was pretty painless and it will revert your 5T back to OOS 4.7.4 no matter what you did to it. Props to Drasm19 from the OnePlus forums and the geniuses behind this tool! Funnily enough, I was ultimately led back here:
https://forum.xda-developers.com/oneplus-5t/how-to/oneplus-5t-unbricking-tool-confirmation-t3733012
You guys more than likely already knew about this tool, but definitely keep this in mind if you manage to brick your phone like I did.
Now I'm back to my original problem: Bluetooth is really messed up. This is what I'm talking about:
https://imgur.com/gallery/eEkbX
No matter what I do, no matter how many times I flash any version of OOS, this is always the result. As you can see, even with the toggle in the "on" position, Bluetooth refuses to do what it's supposed to do and the app takes up 0 bytes. Something is up...
I've searched a lot of threads that reference Bluetooth issues, but it looks like I'm the only one with this problem. I'm open to any and all suggestions that'll help me solve this and get back to using my 5T. I already miss those awesome navigation gestures.
Thanks again for your time and help.
im not really a developer type, but a while back it was easy to root and un root with kingo. and i could put things in the system with FX. please bare with me a sec.. p9's i like, but getting some glitches. when the gboard went byby, on reset, i had to set up my welcome screen by shouting at the phone.. 'at sign' does give you @ but to get capitals you have to trick it, eg. 'USA' to get an upper case 'u'
anyway, i got in, and got gboard from 'my apps' ..fine but of course, wont survive another reset.
so about the missing bluetooth.. iv got the directory info. and the missing files. thanks ..but i didnt want to wipe the phone, it seems rooting has become a can of worms.
wouldnt it be nice if there was a nice (no root) app , to run bluetooth from the apps ? so that 'joe blow' doesnt have to throw his phone away, cos it doesnt work in the car ect.. thanks
I just started receiving the error "Bluetooth keeps stopping" on my Pixel 3 XL a week ago. It comes and goes seemingly completely at random, sometimes clicking close app will work and other times it will just keep coming back over and over until I restart my phone. It's a huge problem because it takes my wifi and sometimes I think even my mobile data down with it. I've read a bunch of posts and it seems like many people have been having this issue.
I've tried turning off Wi-fi and Bluetooth scanning.
updating Google Play system update.
Clearing cache and storage of Bluetooth.
resetting every bluetooth device I own
Factory Reset
sideloading an OTA image
Flashing a factory image
I'm all out of ideas. The only thing I can come up with is it's a hardware issue, but generally hardware issues I run into are not so sporadic and random. Usually it's either broke, or not broke. It doesn't seem to correlate to how hot the phone gets. I feel like Google broke something with an Android update. I've tried to warranty it through Google but I purchased it new on Ebay and they want the original purchasers name, email and order number. Anyone know of a way around that for Google's warranty?
As a last ditch effort I just flashed the Sep 18th Android 9 factory image, crossing my fingers that for some reason that does something.
My only other idea is google has driver binaries posted for pixel devices. Do these binaries get written over/rolled back when the factory image is flashed? Or are they isolated and not touched when flashing a factory image? Could flashing new driver binaries fix the problem? If so, does anyone have a guide on how to flash the driver binaries, google gives documentation for sideloading the OTA or flashing factory images, but nothing for how to install the driver binaries.

Try flashing the dec/Jan build then lock bootloader then start phone as normal setup then unlock bootloader. There's also some Bluetooth settings in the developer ootions. Also check battery settings for the app maybe try turning off optizmation for it. There's also a setting somewhere that will let you turn off the ble236a scan it's always on mine new pair list. But the drivers are usually flash with the update or ota. I needed to flash those when flashing Dirty Unicorns. Fastboot flash vendor_a vendor.img and same for vendor_b believe the other is the radio img you would need to extract them with 7zip if using Windows.
Mine did this as well but I was using naptime,and servicly to kill and or deep sleep quicker. Which is what made me think of the battery optizmation

Just a precaution, as soon as you start locking and unlocking bootloader you're going to be doing a complete wipe of your device. So backup before hand. You'll also want to do a complete install of the factory image, with the wipe option, before you attempt to lock the bootloader. If you lock the bootloader and you are not 100% stock of something goes wrong you could end up with an expensive paper weight.

The error happened once immediately after a full factory image flash before I had downloaded a single program or changed a single setting, so I don't see how it could be bluetooth settings, battery optimization, wifi/bluetooth scanning, or a rogue app. Oddly enough, since posting this last night I've managed to go 12 hours without an errors after flashing the Sept 2018 factory image. buuuuuuuut now I'm afraid to upgrade to Android 10 again.

Thank you for making sure I understood this. Yeah, I generally factory reset my phone and laptop once a year so I always back everything up before a reset. And yeah, I haven't changed anything from stock on this phone since I've had it, so unlocking and locking the bootloader should never cause any issues. As I told Billy, the Sept 2018 image seems to have fixed the problem, fingers crossed.
Is it probable that upgrading once again to Android 10 will cause the issue to return? The Sept 2018 image must have changed an internal setting or driver that wasn't functioning properly.

I can't tell you for sure, but i would think the latest firmware should work. There have been a number of Bluetooth fixes since the original firmware, which it appears you're on now. That, and lots of security fixes.

Yeah, I mean I would much prefer being on Android 10 and having the latest updates, I normally update as soon as they come out. But, given that I flashed the Jan 2020 image and bluetooth was still broken, and then flashed the Sep 2018 which seems to have fixed it, I'm hesitant to go back to the Jan 2020 updates. Kind of tending towards the if it isn't broken, don't fix it philosophy right now. If I had time to monkey around with my phone all the time I wouldn't mind, but the semester just started and I use my phone for everything at school so I don't really have time for it to be not working. >.< Such an odd issue and odd fix.
Looks hardware related, like the cable is loose.

And it's continuing to happen even with the Sept 2018 factory image flash.
Why do you think it's hardware related and that a cable is loose when a reboot fixes it? If the cable is loose a reboot shouldn't fix it.

What do you have Bluetooth connected to when it happens?

Nothing. It doesn't matter whether anything is connected or not. It literally happened on first boot up of a fresh flashed Jan 2020 factory image, before I had put a single thing on the phone.
Generally I have my Fitbit Versa connected, I got 2 tiles awhile ago, but first troubleshooting thing I did was remove the app and delete those from bluetooth since those were my latest additions to bluetooth. I have backbeat fit headphones I use sometimes, the same with bose soundlink ii headphones, ps4 controllers, a jbl pulse 3, my car radio. But I factory restored all of those items so they weren't trying to connect to my phone, and then flashed the factory image. So I don't see how it has anything to do with an actual bluetooth connection.
Im having this same exact issue. Android 9 was always super smooth. It all started with the Android 10 update. I was having all kinds of Radio related (wifi/bluetooth/data) issues ever since. I noticed sometime in Nov/Dec that google released some kind of radio system app update and things got a little better. But I still have the Bluetooth problem (like today, which prompted me to find this thread) or every once in a while ill lose all data connectivity and have to reboot my phone for everything to come back. I LOVE the dark theme, but this has to be the worst Android update from a stability standpoint ive ever experienced.
Just want you to know it isnt just you. Its something to do with some phones on Android 10

Yeah, I wish this thread held a solution for you. I've searched and searched and tried every solution I've found on google and nothing has worked, and really none of the threads I have found have ever had a concrete solution either, just one or two people going "well I did THIS and it worked", and a bunch of people saying it didn't work for them. I just cannot fathom how a full factory flash back to the very first image would not revert the changes that came with Android 10. That's why I was questioning whether or not a factory flash replaces driver binaries. It's the only way I could see the factory flash to Sept 2018 not fixing our issue. (Other than it really being a hardware issue, but that doesn't seem possible to me.)
Oh wow, you're still having same issues on Android 9??
Im still on Android 10, most recent update. I did do a full factory flash a few weeks ago and it was quite the improvement. But I still do have the Bluetooth/radio issue every once in a while, like yesterday.
I wonder if it's a hardware issue and/or substandard hardware performance that Android 10 made more prevalent? That's something we'll probably never know
I only pointed to hardware as I had a similar issue years ago. The radio connections were slightly loose so it would come and go. I do hope you are able to figure out what is wrong, was not trying to be rude.

Oh no, I didn't think for a second you were being rude. And I appreciate your idea, just with what I'm experiencing with my specific phone it doesn't seem to be a hardware issue.
Strangely enough, the issue has been tapering off as of late, after the factory resets I just continued to use my phone while I wait to figure out if I can get a refund or a warranty replacement, etc. The issue has been occurring with much less frequency since then. Still happens, but not like it was.
Damn, the Bluetooth bug is back again. It was so bad the other day, my phone kept bootlooping for like 20 mins while I was on the road.
I finally just let phone sit for a while and it fixed itself. Man this is completely sporadic.

Yeah, mines been better for like 4 days, and then it just crashed and rebooted by itself earlier today.
has anyone gotten to the bottom of this yet? it seems to be a result of the play store system update being "stuck" on Sept 1st...even if you get it to download to the current version, currently March 1st, after a reboot it will not show the March update has been applied. And should it actually show that the March update has been applies, within a day the phone will reboot and the bluetooth bug will return, strangely the update to the play store system reverts to Sept 1st.
I'm having this issue with my son's phone. I tried unlocking the bootloader and flashing the factory img from April but of course the bug is still there, and after signing in the Play Store system is of course dated Sept 1st
There is no fix. I made an official Android Issue Tracker thread.
https://issuetracker.google.com/issues/151033055
and a Google Pixel Phone Help thread.
https://support.google.com/pixelphone/thread/32828289?hl=en
Google's being ****ty about it. I eventually just bought a new Pixel 4 XL. I needed a functional phone for school and work, and as much as I hate to spend money on another Google product after this mess, they do make the most powerful pure android phones with the best camera. Ebay FTW, $600, never giving them another penny directly.
If you still have warranty, get it warrantied immediately, and don't take no for an answer. I dawdled around thinking it would get fixed and even though I reported that I was having issues with it directly to Google's phone support BEFORE the warranty expired, by the time I called a second time and pushed a manager to see if they could warranty it, my warranty had expired so they told me to go jump in a lake.
to make it worse, Google told me the phone still has an extended warranty but I'm not the original owner and have no way to contact that individual. But you need that person's email address for it to work. So it was purchased but because of this technicality it's null and void. I get the security of it but it's still garbage
I seem to be having issues occasionally with apps being unable to restore sessions or being able to login into them, often completely loosing logged in sessions and not being able to access it properly until I reboot. I have also seen it let me login with finger print but not with the pin code.
I initially thought it was an issue with the ROM but I have since been on two different ROMs - Paranoid and now NameLess - and have had the same issues on both of those. Sometimes it seems to happen multiple times within a short period and then sometimes days so not sure where to start tracking it down or if there's some hardware issue in my device.
If anyone has any ideas what to try I'm all ears although I'm resigned to it happening now but figured I'd put it out there in case someone else has experienced it
Have you used MSM Tools to reset your phone between your two installations? Maybe it came from the A12 version used by Paranoid and the file concerned remained untouched when you changed for NameLess (which would be strange, considering that a majority of custom ROMs installations processes ask you to factory reset your phone)?
I didn't use MSM tools but I did reset to the original firmware/latest oos11 in between them. But I have just thought that perhaps slot b doesn't have the right stuff in, even though I made sure to do an update it was on slot a till a crash a couple days ago and that's when it started going wrong on nameless. I'm going to try switching it back to slot a later and seeing if it happens again. If so I know it's something on slot b. I'm pretty sure paranoid ended up running in slot b too and the last oxygen I actually used was slot b.
If so I'll try MSM tools to make sure it's got the right stuff in each slot. It's the first time I've done custom ROMs for a long time so probably missed something. Thanks for your suggestion. I'll have a look
