Help Please [SM-T377P] - Samsung Galaxy Tab E Questions & Answers

So at some point when wiping/flashing LOS 15.1 something got messed up & it just keeps rebooting before the boot screen loads. It doesn't matter what I flash now, it does the same thing, all except for the firmware file from Updato. That booted into 7.1.1 (though it took a while), I tried flashing LOS after but it still goes right back to the reboot loop. Any help would be much appreciated.
[edit]
So I found a full backup & got that restored using TWRP 2.8.7.0, that booted up only to tell me to put my sim card in, no clue where that is, never used it (used tablet). I flashed 3.2.3, LOS 15.1 & 16.0 so far, neither will boot, they just get stuck on the boot screen. LOS 14.1 just reboots before the boot screen.

I've tried to use the Bootimage Debug Addition patch from here to grab some logs but it doesn't seem to be working, any help would really be appreciated.

So I take it I'm just out of luck then?

Oneplus2 Stuck on Animation

I have a US Oneplus2 that is stuck on the animation when it boots. I can get into TWRP and Fastboot, latest TWRP works and can also use an older version that I had.
I made a TWRP backup that I pulled off onto another computer. I then installed OOS 3.5.1 (I think) to do some testing. Once I was done testing, I decided I wanted the latest lineage as my backup was a 6 month old version of the latest at that time. I used TWRP to wipe the data, cache, and system to then install the latest Lineage 14.1 11/24/17 and gapps mini and micro (tested both). It gets to the lineage boot animation and the ball goes back and forth forever. I have left it over night and it's still going. I have rebooted the device, installed lineage several times, moved to 12/1/17 today with the same results.
After messing with it for hours and days, I decided to just put the TWRP backup back on the phone and then update from there. Well... my custom animation is load but the animation is also going forever.
Looking for some help on what might be wrong with the phone, thanks.
Make sure everything is formatted as ext4 and update firmware to 3.6.1 just to rule it out.
I would use the latest twrp.
I go to format tick all the boxes and clear everything then go to reboot > recovery. Once back in twrp copy the ROM and gapps across from pc install ROM and gapps together, wipe cache and dalvik reboot.
I'm in the process of doing that now.
The TWRP that I'm using is 3.1.1-0 which looks to be the latest. I am working with OOS 3.5.8 but will look at downloading 3.6.1. I am working to get Lineage 14.1 on there once everything is stable.
I ran into another weird is when using the qualcomm recovery tool:
My method is to enable ADB, enable OEM Unlock, enable Advanced Reboot.
Reboot into fastboot
Fastboot oem unlock: is successful
Fastboot reboot
I then go through renabling ADB and Advanced Reboot, OEM Unlock is still enabled.
I then reboot into fastboot
Fastboot flash recovery twrp-3.1.1-0-oneplus2.img
This completes successfully and then I fastboot reboot.
I have tried several times to get into TWRP but I keep getting the stock recovery.
I have tried to reflash recovery but nothing ever changes.
Is there possibly something wrong with the OEM unlock that says it was successful?
How do I go about troubleshooting this?
Ok, I fixed that and install OOS 3.6.1 and then was able to install TWRP 3.1.1-0.
I then wanted to install Lineage 14.1:
I then formatted Cache, System, Data, Dalvik... everything but internal. Should I wipe internal as well?
I copied over linage 14.1 and open_gapps for the same build micro.
I now am back to getting the Lineage Boot animation.
Thanks for helping since I'm trying to get Lineage to boot.

Internal doesn't really matter to be honest, did you check they data and system are formatted as ext4.
It is in twrp advanced wipe options.
Did it ever boot ?
I did doubt check the data and system are formatted as ext4.
I let it sit for 3-4 hours and didn't see any progress.
Try a different rom. There are a lot of lineage based roms around.
I tried that and am getting the same results. Even if I flash a full TWRP backup from a time when I had it known to be working it happens.
I've tested this with 3 different roms now. My latest attempt has been to update TWRP to 3.2.1 and then install lineage 14.1 20171208. I also tested with Paranoid and Carbon because they were near the top of my list not because I know anything about them.
The phone just never gets past the boot animation. If I reboot to recovery is there a log I can pull to see what the issue is?
Thanks
Would like to see if anyone has any thoughts. If I run OOS I can use the phone but as of right now I can't use any other rom.
Is there any advanced fastboot or wipes that can be done to get it to boot. Is there any type of debugging that will show me what's happening when it tries to boot.
Just trying to bump this, I really need a way to debug this problem. Besides running OOS, I have a feeling this device is bricked and the mega unbrick guide doesn't work.
Also looks like if I try to put Kali on top of the base 3.5.8, the phone goes into the animation loop. So any change after OOS on the device puts it into an animation loop.
Is there a way the system or boot locked? Even thought I can TWRP anything onto the phone without errors.
Hey!
I've got the same issue it seems, phone just sticks to boot animation when flashing any other ROM than OOS 3.6.1.
Any update?
EDIT :
problem was with the persist.img
Flashed a different firm file and it was resolved

OOS does not refuse to boot if a mountable partition is corrupt. This is not the case with lineage. If a mountable partition is corrupt and the corresponding fstab entry does not allow lineage to format and somehow mount it then init never proceeds
Try flashing this file: https://glassrom.botstack.host/firmware/oos-3.6.1-firmware-signed.zip and try again
Note that this file reboots the device after the flash is done so don't use twrp queue to flash this file. Flash this file last

Alternatively this is a method I don't recommend to beginners because they accidentally give twrp logs to devs without realising it
You can get logs by making the forcing the device to "crash" through the power button
Here's how it's done: you boot the non-booting ROM and wait for about a minute. Then press power + volume down while it's on the bootanimation. You have to hold it until you see the oneplus logo and boot to twrp
TWRP's kernel will recover the last booted kernel's log from ram and place it in /sys/fs/pstore
First you have to open the log yourself to check if it's valid. The file is console-ramoops-0. All other log files in that location are invalid for your specific issue
Now for an ordinary user this is hard. They can't tell if the log is a recovery log or a ROM log. Since we're dealing with official lineageos we assume selinux would be enforcing
You want to search for this string "permissive=1". On Linux just do cat console-ramoops-0 | grep "audit" (quotes are part of the command)
If you're on windows then you can download Linux and get the logs. Stop bothering me
If you see the string "permissive=1" in the log you have accidentally fetched a recovery log
Go back and boot again and wait for about a minute if selinux is permissive
The string should read
"permissive=0"
That means selinux is enforcing and this is indeed a ROM log
Send this log here
Hello,
Was this problem ever solved? I am experiencing the very same thing with every single ROM i have tried so far. TWRP is installed, I can install all ROMS but when I try to boot the phone, it just won't get passed the booting animation.
Thank you

SM-T580 flash with LineageOS 16 stuck on lineage logo loop

I installed TWRP 3.1.1 using the ODIN patched version and was successful. I had let the system boot into the samsung original stock from where you see "HI" then I rebooted it into TWRP to attempt flashing and I got the /data partition couldn't be wiped. So I ran some of the other repair functions in TWRP and that appear to have fixed it. I then flashed with the latest LineageOS, Gsap, and Magistk20. When it boots up the LineageOS I'm stuck on the Lineage Splash screen. I've let it run over night and it has't changed anything. Any advice?
I recommend trying to wipe the system and reinstall LineageOS with flashing Magisk. If the same problem occurs. Just wipe the system and flash LineageOS without installing Magisk.

Here's how I think I fixed it.
booted into TWRP
advanced wipe, Factory reset
booted it into TWRP
Flashed the LineageOS
boot into LineageOS
boot it into TWRP
flashed the Gapps.
I'm up and running now. I tried different iterations and It really bothered me because it worked fine on another one. I was also at time flashing it with SuperSU and other times with Magisk. It didn't matter which one I used it got stuck on the LineageOS splash screen.

By the way, it's called the boot animation. The splash screen is like the Samsung screen that says powered by Android.
Possible corrupted file

So far you're quite correct I personally have three SM-T580's and they all seem to work just a little bit different. Might I suggest doing an MD5 Sumcheck? The device shouldn't be getting into a bootloop unless there was something wrong with the files, or the device.

Trouble installing custom rom

Hi - so I unlocked my bootloader, installed TWRP no problem. However I boot into TWRP abd select ADB Sideload - but it will not load. Installed via OTA/USB instead - tried flashing Lineage and AICP - both start the boot process but never complete. Lineage boot me back to TWRP, AICP just stuck on loading screen. Tried cleaning cache etc etc still no dice. Any ideas anyone where Im going wrong....I was previously on the latest stock rom.
Fortunately I can still access TWRP and bootloader etc fine.
Thanks!

You must be missing some steps before flashing, like "FORMAT" your data partition instead of just wiping it.
read the instructions more carefully next time

LineageOS 17.1 bootloop error.

Heyy. Could you help me with this.
So I installed LineageOS 17.1 some weeks ago on my G928F Samsung Galaxy s6 edge+. And have a little problem. My phone is stuck in a bootloop. My phone shutdown because it didn't have battery left. I put the phone to charge and when I tried to power on the phone it just went in a bootloop. I tried several things to make my phone come back. The closest I get was that my boot animation started. But it just went off and again in the bootloop. I tried to wipe cache and dalvik cache. I tried to install boot.img file from the custom Rom zip file. Also I tried to change the boot animation but I can't see the /system/media folder. And I don't want to lose my data. Other detail, I don't want to dirty flash LineageOS 17.1 every time my phone shutdown because there's no battery left. Could you help me?(Sorry my bad English, I'm from Spain)
Nevermind
No problem. I already installed the stock Rom. Because some of important things that the stock Rom has the LineageOs 17.1 don't and that way I make sure that I won't have problems again.

Cannot install LOS as per LineageOS instructions

This phone has had a number of previous installs of ResurrectionRemix (2019), LineageOS 18.1 different versions and there has not been any problems to install custom ROMS. Just recently, after recharging the phone, the phone would not boot. Kept hanging on the LOS boot animation. I have reverted to Stock ROM successfully, and after that tried several LOS reinstalls with the recovery bootloader (either TWRP or LineageOS's own) but every time the LOS install starts hanging on the boot animation. Timeout. And I am trying to reinstall same versions that have been working before. Total mystery. How do I get a working LOS back on the phone? Strange thing is that a ResurrectionRemix install seems to work. No hanging at boot there at least.
What is causing this peculiar error? NB: I have never used any apps like Magisk or similar.
BR /Johan
try it with twrp
I have tried with TWRP running from 3.3.0+ up to 3.6+ . No difference here. It feels like the LOS installation is missing something. A partition or what not. adb logcat does not work when I boot so I can't see what's going on during boot, but I can use adb with the LOS recovery to look for things .
Update: Finally got the boot logging to work. It turns out that my fingerprint sensor is dead, and LOS gets into a bootloop when it tries to access it via HAL(?!). I am no expert on debugging - thanks to guys over at #lineageos. But it is worth noting that LOS might get into a boot loop if the fingerprint sensor is dead for some reason, be it an electrical failure of some kind or firmware issue.
