Interesting Issue concerning no OS, but boots fine - OnePlus 3T Questions & Answers

So I've had my oneplus 3t for a while as soon as I got it I did the standard magisk root and so on, however the other day I tried to move a app to system files. And it said failed. Confused. I decide to go back to a backup, when I got to the twrp I realised I'd forgotten to put a backup on my phone. Oh well, I'll just reboot and worry about it later, then a screen poped up, no OS?
The odd thing is it boots up into oxygen os no problem in seconds after I go past the two stupid warning screens ... I'm really confused as to why that is? Anyone have a clue or any ideas?
Thank you in advance.

Sounds like you may need to do a clean flash?

Dead Turbo?

So I was running CF 1.3 base for quite a while with no issues. Two days ago my phone shut down on me and would not boot. I wipe everything multiple times. I wiped cache. I did a factory reset, nothing... I wiped again. Nothing.
It gets past the Motorola logo and then just sits at the boot screen. A couple of times it would say updating android, it would finish, but then it would go right back to the boot screen. After about 8 hours it finally booted and I used it all day yesterday. This morning my issue is back. I've flashed different images to see if it has something to do with 1.3. It's all the same. I think I might try to go back to kit kat. It seems to be a software problem, but I am starting to think that something most be wrong with my hardware.
I found this thread: https://forums.motorola.com/posts/b0021413e7
I think my phone is shot... Any ideas?
When I had my Razr Maxx I had an issue that was similar and nothing I tried would fix it. Factory reset cache wipe flashing different roms nothing. Finally I decided to factory restore it with RSD Lite and after that the problem went away and I was able to do everything again like normal. I don't know why a factory reset wouldn't fix it and that did but it did.
Thanks. That is my next step. Do you know where I can find the RSD image?
Is this what I need? http://forum.xda-developers.com/dro...quark-stock-firmware-moto-maxx-droid-t3063470
Do I need to worry about flashing radios and stuff back to 4.4.4?
Seems to be. Honestly I've used it on many Motorolas in the past but I haven't read much about using RSDlite on the turbo. I would just do some googling around I'm sure you'll find it

This just happened to me yesterday. Long story short, I have a strong suspicion that something about the recent Moto Actions update is breaking our phones for reasons that I describe here: http://forum.xda-developers.com/droid-turbo/help/complicated-problem-restore-doesnt-help-t3184251. I managed to fix it, but I re-broke it because I'm an idiot and the method I used before isn't working. If you get it fixed and get your 1.3 CF image back up and running, I would strongly recommend against allowing the Moto Actions update. I have a feeling that we're going to be hearing more about this soon from other people.

That makes sense, after I finally got mine going, I updated Moto Actions and all the other apps it crashed again in about 12 hours. If I can finally get it to boot again, I think I am going to test your theory. If you figure out how to get it booted again, please share!
Edit, which rootjunky image did you flash? SU2-12?

I did get it booted again. I flashed the kitkat update (not the stock, stock update 1, which is what you should be on if you're using mofo) file on the firmware thread that was posted here using the version of RSDlite that was posted there. The key is just to wait a really, really long time. Even if the screen goes black, it could potentially still be booting, especially if the back of the phone gets warm. I left it plugged in, let it get to the boot animation and left the house for several hours, and when I got back it appeared to be functional, but things were slow and choppy at times and my home button didn't work. The settings menu from the pull down menu didn't work either. I had to access settings from the app drawer. I tried a factory reset from the settings menu, and that just re-broke everything. So now I'm back at square one. I re-flashed the same image using RSDlite again, and now I've waited about 10 minutes and I'm still looking at the boot screen, which at this point is normal since the problem occurred.
I got a hold of an old copy of the Motorola Sensor Services apk. As far as I can tell, this is the apk that is replaced by Moto Actions, which according to Google Play is only compatible with 5.0 and above. My plan for tonight is to wait until the thing decides to boot, attempt to start the stock Sensor Services app and get it to do the sensor firmware uninstall that I mentioned in my other post. If that doesn't work, I'm going to try to install the apk that I found and see if I have any more luck with that. I'll report back here when I get a chance to do that. Let me know if you figure out a solution.

Yeah, I used SU2-12.
I followed the procedure outlined here to go back to stock. https://www.youtube.com/watch?v=6avEPGWB8E0 I used the SU2-12 file, but I lost everything... Thanks for the help. I hope there is a fix for this soon! I'll test your idea about MOTO Actions and report.
Edit: Well, I thought my phone was booting when I wrote the above, but it has been 30 minutes and it has not booted...
So, I can get it to boot - although it is not easy and it takes me like 30 minutes and I haven't found a full proof method yet, but after it goes to sleep I have to start the process all over. It has been a frustrating 3 days.

I think you are onto something. I'm currently on 4.4.4 and it is bone stock. When I go into the Play Store it shows that I have Moto Actions installed, but when I click on the app it says that it is not compatible with my device. I've tried wiping the data from the app, force closing it, and clearing the cache. None of that has prompted me to uninstall the sensors. By the way, I found the Moto sensors app and tried doing the same thing, no luck.
So, I think I have the 5.1 Moto Actions installed still, which is causing the 4.4.4 image to freak out. I've thought about trying to go official 5.1 and see if that fixes it, but since I have a replacement on the way, think I might just leave it be - unless someone (like you) figures this thing out.

I ended up getting a replacement from Motorola too. If it has 5.1 on it, I'll sell it and get one with 4.4.4. Thanks a lot for the tip, by the way. I might still work on it just as a hobby, but I'm out of ideas. Of all the many, many devices I've tinkered with, this is the first one that I ever permanently messed up, so I'd like to fix it as a matter of pride, but I now only have 48 hours to do so. After looking at logcats, the partition table of the phone and the androidmanifest.xml of the motorola sensor services apk, I'm pretty much certain that this app writes those sensor drivers to a partition other than the ones that get flashed when we up/downgrade (ie system, boot, recovery, etc.), which is why these processes don't fix the problem. Theoretically, if I knew which partition that was, I could find someone with a working Turbo who could dump that image, and if I get lucky and it's a partition that isn't sig checked by the bootloader (like the radios, for example), I could flash that and be good to go. I have no idea how to figure out which partition that would be, though. The obvious choice was the "firmware" partition, but that partition has a lot of drivers that seem to relate to lots of different important things, so messing with that seems scary. I also don't know anyone who is knowledgeable enough to generate that image (myself included), so it's a moot point.

My question is why hasn't anyone else's device gotten borked since the update? I've had it since the update was distributed with no issues and use Moto Actions continuously. Seems like if it really is a combination of writing drivers to a partition that isn't compatible it would be a universal issue. If only 2 people who have a mofo'd 5.1 IMG (out of probably hundreds) experienced issues my bet is on some weird glitch that occured when you initially flashed the updated firmware to get 5.1 working on the mofo'd device, rather than some general driver incompatibility.

I agree. Either it was a corrupt driver installation that worked just well enough for the app not to realize it, or the firmware update happens silently only when requested (similar to Google play services), and we're all one chop chop flashlight away from a phone apocalypse. Hopefully it's the former.
So, I went ahead and updated my device to official 5.1 and the problem is still there. The moto actions app that is installed still says that it is not compatible with my phone. I have cant figure out how to clear it or delete it or anything. And when I think I have it, I let the phone sleep and I can't bring it back to life again without waiting for a 15 min+ boot. Oh well, at least the bootloader says "official" now rather than "modified." So, Motorola should not complain about it. Thanks for trying to figure it out @TheSt33v

Good to know. I picked the $25 option specifically because the free one requires an inspection, but I'll probably update it anyway. I'm not surprised that it didn't solve the problem though. When we flash those upgrade/downgrade images, we're basically just doing manually what RSD lite/Verizon upgrade agent does automatically.

you called it! Just spent 2 hours reflashing 1.3 first repeated V4A, then Base. flashing sick Android upon Recovery attempt, FAIL. reflashed radios and such and with different "vol& pwr" sequence was able to get in to wipe cache. Not hat it would help me but i viewed chche Logs and im wondering if, to the right person, it would help to have copies of them?? It's a bunch of pages tho and and not sure if it would help.
My plan it to, in Recovery, Factory wipe, then reboot to Bootloader and attempt to flash base. W/ all sys.img's, then wipe caches again. ihave read the whole thread early yesterday morning but i fell asleep prob 20 times during. it was like 3 ishi think SO, i'll now go re read probably to find that you've already ruled out "my plan"

Damn. I was hoping I was wrong. Yeah, I did what you suggested many, many times. If you end up reflashing 4.4.4 and you see the message to uninstall the sensor firmware, do it and FLASH NOTHING ELSE until a solution is found. If not, it's really easy to get a new one from Motorola.

O Jeez, xda gave me a " token timed out message" but only after I hit post reply and, it was a novel! I have to get at least 2.5 hours sleep tonight because that been normal lately. Besides setting up Moto functionality, I'm golden and I do have their updates blocked best I can anyway. Hope all is working.

[Q] Android Process FCs and General Device Instability After Flashing MMB29V

Hello all. Generally I've been able to troubleshoot all my Android issues on my own. Most of the time someone has had the same problem (amirite?!). However, I'm stumped and could use a little help from the community.
I've been going along on Marshmallow with FK as my kernel. Generally, waiting a bit to take an update til SuperSU was confirmed all working correctly and that there wasn't any surprises. I had been putting off the MMB29V update for a bit just because everything was running fine and I had no real reason to upgrade. Well, one day I started getting a few FCs and things seemed a bit off performance wise so I decided that I'd go and move on to the next release.
Now, since I've had my N6 I really haven't had the need to run a custom ROM which is completely unlike my old habits on the S3. I decided that it's been a while since I've checked out AOSP so I flashed MMB29V using the batch file with no issues and then DU and their recommended GApps. Here's the first hint of an issue. When I loaded up the OS for the first time I got acore and phone FC's constantly. I instantly thought that I didn't wipe something or that I had a bad zip. I re-downloaded everything and checked MD5s. Everything looked good and after the flash I was able to get through the setup wizard without any issues. As I was sitting there checking out the tweaks and options available I started getting FCs again. It seemed related to Google apps. I did the whole process a second time and still had the same issues. Basically it seemed like at some random point in time the FCs would come and then shortly after the device would be highly unstable. I'd get random reboots, etc. Looking at the stack traces the errors seemed like odd NPEs and native errors.
I decided that AOSP wasn't going to cut it right now if I was going to have a relatively unstable phone and went to flash completely back to stock. Much to my surprise I still got the same errors! Apps like Feedly would never even be able to open. They would just FC on launch. The device hot reboots. The phone process seems to crash during most calls. I triple checked my MD5 on the download from Google. Made sure I wasn't doing something super stupid. I even tried doing the factory flash, booting to the welcome screen, then powering down, going to stock recovery, and factory resetting before continuing. All the same errors.
I've flashed back to complete stock a few times before without any issues. I've been able to flash system.img without any issues. Now it seems like the phone is completely unstable no matter what I do. I get the "Your device is corrupt. It can't be trusted and may not work properly." (red) message when doing a cold boot.
So... What gives? Am I completely blanking on a step here? Is it possible that I have a hardware issue that is corrupting stuff (I've suffered a bad DIMM before in a desktop and it was mind numbingly frustrating)?
I've burned through two backup cards of Google 2-Step backup codes! I'd really like to figure this one out!

You could read the OP of the following thread and flash a debloated and prerooted ROM.
http://forum.xda-developers.com/showthread.php?t=3059493
I guess I'll try that. I'm still scratching my head why a flash from the factory image is still suffering from FC's and general instability. It also concerns me that I get the corrupted message at boot. It would be one thing if I flashed factory, then put a recovery, kernel, and rooted, but I haven't done that.
Hopefully I'll get a chance to try that this evening. Thanks for the link to that image. It's pretty much what I run when I take an update.
N, n, ne, necromancy!
I brought this thread back to life because I've never been able to solve the instability issues since my last post back in March.
Having some free time lately I decided to nuke my device and start again. I first grabbed the latest stock image and flashed stock. Then I downloaded the latest TWRP and Dirty Unicorns and decided that I'd give it a whirl again. I had FC issues right after the first go at it. I decided to try another GAPPs and do it again. I was able to get through setup. It took a few hours but the FCs started again.
I decided that I would try factory resetting the device and then starting a setup. I remembered that on my previous devices that I sometimes would have to do an immediate factory reset after flashing.
Well that did crap. FCs are random. The device is stuck booting now after a hot reboot.
How can I debug this? What do I need to grab from a logcat? Is there a way to run something like memtest to see if there is a bad section of RAM and something against storage to see if there is a bad sector?
This is frustrating as hell!

I Think I Trashed my Tab S2 T713

I am coming with hat in hand fully expecting to find out that there is no solution and I am out the $$$ it will cost me to replace. After having this device for close to 2 years, I decided I would root it. I have 5 other devices currently that are rooted and numerous others that I have rooted over the years (including Samsung). Admittedly, I dislike Odin and a lot of other things about rooting Samsung devices. That is part of the reason this was the only device that I ever kept unrooted for more than a month or two. I installed twrp_3.1.0-1_sm-t713_14417n with Odin with no issues. I had SuperSU 2.82 in internal. When I got into TWRP to install it, I saw nothing but directories in internal and it became clear to me that it was encrypted. Attempts to mount, wipe and even reset data all ended up with me booting back to TWRP. I'm sure frustration set in the more things I tried, but now I can't even shut the device down from TWRP or by long pressing power and volume down. Even that just goes back to TWRP. Obviously, I can't get into download mode or system. I just get the recovery booting set warranty bit: recovery message when it starts back up to TWRP. Can't say I have ever seen a device that can't even be forced to shut down, LOL. Thanks in advance if anyone can help.
*I've made some progress. I managed to back door my way into download mode by installing the boot.img from the external SD card. That didn't fix anything, but after that I was able to hold down power down and volume and spam the home button until I got to the download screen. I was able to get back into Odin, but the full firmware file I tried to install errored out at the end with a rev check fail. Hopefully, it was because it thought it was downgrading, so I am downloading the newest file now. The samsung-firware.org D/L is brutally slow. Has a few more hours to go, and I am not positive if it will work yet. Cross your fingers, and throw out any ideas if you have them.
Well, it's alive. Everything is back to normal (except needing to reinstall). Time to root now, LOL!
OK, tried again and ended up restoring the full image again (minus D/L time at least). I am ready to scrap root on this device. I have tried to do everything in the [TWRP 3.1.0-1][ROOT] Galaxy Tab S2(2016) - SM-T713/SM-T719/SM-T813/SM-T819 - 1/4/17 thread. https://forum.xda-developers.com/tab-s2/development/twrp-3-0-2-1-galaxy-tab-s22016-sm-t713-t3390627 I would have tried installing no verify, but no matter what I do not see the SU and no verify files on the tablet either after format data without reboot or after rebooting into TWRP. After the format, it shows that data is mounted. Looking at the pictures in the thread, I think maybe it needs the work done on the external SD but the instructions say nothing about that. Time to sleep on it, and maybe someone smarter than me can think of what I might be missing and maybe better step by step instructions are available. At least it is up and running, KNOX trips be damned. I'll post to the TWRP/ROOT thread. BTW, the OS version I am running is XAR-T713XXU2BRB2_T713XAR2BRB2-20180206.
Well, thanks to some middle of the night assistance from ashyx and about 3 hours sleep in the past 48 hours, I am not only restored and working but now rooted with TWRP 3.1.0-1 and Magisk 17.1! Time for a nap.

I am thinking about rooting my T713. Are there better instructions? What did you have to do differently?
I'd like to get it a go, but the instructions aren't as good as for the many devices I've rooted in the past.
Thanks!

The instructions in the TWRP thread are OK, but they could be a little clearer in some places. Take a look at the interaction between ashyx and I towards the end of the TWRP thread.

HELP, I think I may have finally killed my Tab S2 (T710)

Over the past couple years and up until last week I've been able to kill and revive my tablet. This time I'm really stuck.
Setup: I have TWRP running fine, not sure if it was 3.5.2_9 or 3.6.0. I've playing around with different ROMs for the past few weeks, seeing which one I wanted to use. Friday I reinstalled LineageOS 18.1, but I click the replace/keep up to date option which now guess replaced TWRP because it was no longer there when I booted in recovery.
I've tried reinstalling TWRP, CF autoroot, etc. But the closest I've gotten is TWRP coming up, then displaying errors quickly and the system rebooting. I know just enough to be dangerous, but not enough to know exactly what I'm suppose to do in what order to get the system back up (or which versions of the files I've downloaded I should actually be using.
Any help to get back to where I can run TWRP again would be helpful, I can probably take it from there. I can get the tablet in download mode, but that's about it.
We have same device, but still i can't upgrade my tab in any roms. And unable to install TWRP higher than 3.1 version.

Over the past couple years and up until last week I've been able to kill and revive my tablet. This time I'm really stuck.
Setup: I have TWRP running fine, not sure if it was 3.5.2_9 or 3.6.0. I've playing around with different ROMs for the past few weeks, seeing which one I wanted to use.

Have you just tried flashing stock firmware, using odin?
I was trying the CF_autoroot (and other kernels(?)) and TWRP in odin.
Oddly over the weekend I left it plugged in for a day and and when I opened the cover it was in TWRP.
I was able to wipe, format, and load a ROM. But I think I might have broken the battery connection now, it doesn't seem to want to plug into the main board. So it doesn't want to do anything now. I'll probably play around with the connector a bit and see if I can sort that out.
But I'm not sure what @rufio85 issue might be and I would be the last person to advise anyone on this stuff.

Question How do you run an ADB command on a bootlooping device?

I have uninstalled a system app that I shouldn't have (something to do with network conectivity according to the recovery log) and everything was fine until I updated my device. I hadn't restarted it since removing the system app but after tyhe update it will no longer go past the Samsung galaxy logo. I remember doing something similar to either this device or another and I remember that I was abler to get into the system enough to be able to reinstall the neccessary app and fix the problem. However, this time I cannot get into adb at all. adb won't show any devices when in recovery, download mode, or at any of the three stages of the boot screen. I have tried wiping the cache and everything but factory resetting it as I have data that I can't lose. Any help would be appreciated whether getting adb install-existing to work or to pull important files off of the device before a reset. The device runs android 12 not rooted.

Go back via odin to the original firmware including the correct BIT.

Flash in Odin using home CSC file, simple
You only need to run ADB in Windows PC terminal or DOS mode in order to Odin flash firmware. No need to run ADB commands in the phone.
Just be sure that you install the "Samsung ADB Driver" into your PC before
you try Odin flashing firmware.
Just be sure you download the proper firmware for your phone.
Good luck, have a great day and have fun!
Thank you to all the help, but eventually I got into the phone. For anyone who may encounter a similar problem in the future:
After the phone reboots enough, it resets all preinstalled apps and removes any user installed ones and goes into safe mode. From here, the phone goes through the initial setup screens but all data is still intact, just not apps. Concerningly, it doesn't ask for you to enter your password, it just puts you on the homescreen, which seems bad from a privacy perspective as any samsung repair tech can easily cause the phone to boot loop. From here, you can back up anything important and factory reset. There is no way to exit safe mode once you've gotten this far.
I don't remember why odin didn't work, it may have been that I couldn't get the firmware to download as Samsung likes to change that stuff all the time or it may not have reinstalled the system app neccessary.
I should've been more clear in the original post but I have not flashed any unofficial firmware just the U1 firmware to remove carrier bloat, but that was way before this occurred. In case it wasn't clear, the problem happened because through
Code:
adb shell uninstall --user 0 package.name
an important system app was removed (something network related) which caused android to crash when trying to start the service. In short: be careful what you remove when using adb and, for all you forum members: read the whole post instead of jumping to conclusions about the user's mistake and if it isn't clear, ask for more details. Again, thank you to all the helpful comments even if they didn't end up working.

May I ask how long it took to "reboot enough"? I'm having issue updating to Android 13. It got into boot loop (the 2nd time actually. I mentioned about it in another thread a few weeks ago. Today I decided to try again). Anyway I am wondering if there's anyway I don't need to reset the whole thing. What you described interested me.
Thanks

Sorry for the late reply,
I don't know how many times it needs to reboot to go into safe mode but it seemed like quite a bit maybe 20-30 times possibly like 100. But once it does it'll go through the initial setup screens and let you in without a password. It's very important to backup everything on your device before you mess with any system apps or update especially if you've previously messed with system apps. I however don't use google hence I didn't have a backup of anything and needed to get it off before hand.
It could also be possible that Samsung removed this back door in android 13 and just the act of trying to update it gets rid of it. I don't know I'm just throwing around ideas.
Rule #1 - if a OS is fast, stable and fulfilling its mission, let it be! Firmware upgrades/updates can and do break Samsung's.
