[Help] Bootloop animation. Z3 Compact

Hi. I've got into a problem.
Recently I unlocked the bootloader and rooted my phone. Then I installed Lineage OS. When I tried to go back to stock ROM,flashing it via recovery, it got stuck at boot animation (blue waves).
Other ROMs based on AOSP, like Carbon ROM, and the same Lineage OS can boot and work fine. But when I install Sony stock based ROMs, they just get stuck at the animation.
I've tried many things.
-used factory reset in recovery several times.
-tried different ROMs (the same problem happens just with stock based ROMs, while Custom are working)
-tried locking the bootloader and using software repair with Xperia Companion. Getting an error everytime
-tried flashing with flashtool by androxyde. It just aborts the flashing when I connect the phone in flashmode. It says :
error : null
erorr : flashing aborted.
Will be glad for any help.

So. I just fixed this problem, after struggling with it for about 3-4 days. Maybe this "magical" way will help someone that will get into this problem too.
-I had Lineage OS installed on my device
-downloaded eXistenZ Marshmallow - v5.6.5 (which is based on stock sony firmware) from a XDA post and transfered the .zip to internal storage
-entered recovery and did a factory reset (wiped data,cache, dalvik/ART)
-flashed the eXistenZ from internal
-I got stuck in the animation boot (strangely, the animation was from Lineage OS
-I powered off the device
-opened the flashtool and the flashing process started, without any errors.
Now i'm back on stock firmware, and it loads without problems. I guess Lineage OS deleted some files required for stock roms to work properly/flashtool to start the flashing process ,and the eXistenZ mod added the missing files. I just don't find any other explanation.

A Bit of a Complex Issues Involving TWRP, SuperSU, and not being able to restore OS

So, I recently installed TWRP on my SM-T813. I then flashed LineageOS 14.1 successfully, but didn't like it, so I reflashed stock ROM. Everything was working fine, until I tried to install SuperSU on my stock ROM.
Now, my tablet is stuck into booting recovery mode, and cannot boot into the ROM (although Download Mode is still usable, more on that later). Upon trying to reflash the backup again, and attempting to reboot, TWRP states "No OS installed!" SO I tried reflashing the LineageOS ROM, same thing. Upon trying to restore a firmware with Odin, I get an error saying "SW REV CHECK FAIL aboot Fused 2 Binary 1." After finding no answers, I delved into my SD card and found that I had flashed the WRONG version of SuperSU, although it had been cleared when reformatting with TWRP. I then tried using the CORRECT SuperSU, and I am still stuck in recovery bootloop.
Can someone analyze what's going on and see what the problem is?

This has been posted a million times all over the forum. A quick search here or Google would have revealed the answer
You need to flash a revision 2 firmware. So that would be something like t813xxu2 in the firmware build number.

Sorry for being late with reply. Your advice helped me fix my tablet! Thanks so much!

Galaxy Tab S2 not booting properly.

Hello everyone,
I recently wanted to root my galaxy tab s2 and install a custom rom on it to enhance performance, someting i've done before with my old phone where everything worked fine. So i used autoroot to root the tablet which worked fine and choose to install lineageos afterwards. i found a fitting version of lineage on their official website, installed twrp on my tablet and used it to install lineageos and GApps. However i did not unlock my bootloader using adb since i didnt have to do that back when i rooted my phone and i read on a forum that unlocking oem in the developer settings would be enough. This is where the problems start. After i installed the custom rom the tablet would try to boot into the os for a couple of minutes only showing a loading animation just to boot straight into recovery mode afterwards. In an attempt to fix the error i used odin to install a stock rom from sammobile on the tablet. However now it doesnt even boot into recovery anymore. instead it only shows the stock rom loading animation until the battery emptys. Though i can enter download mode from that position and then cancel it in order to reboot the device which enables me to enter recovery mode. Does anyone have an idea how i could boot a normal os again or is the device hard bricked? The only idea i have left is trying to install a new os from an sd card.

I have the same issue. I installed unofficial lineageos 16 to exynos 2015 t810. I have newest odin and twrp. Im wondering if i need to install or unlock the bootloader to get past the logo loop then recovery bootup after 5 minutes. I followed clean tutorials.
Update: i found this to try.

- addonsu-16.0-arm-signed.zip
- open_gapps-arm-9.0-pico-20191009.zip (some with nano or stock)
I am doing a full clean install every time (over 10x so far) but only get it to boot using the ROM alone. Any mod, such as addonsu, gapps or even trwp app cause it to show the Lineage boot screen for quite a while until dropping back into TWRP. Since there is a virtually infinite amount of permutations which versions to try - can someone who is successfully installed 16.0 with Gapps on a T710 let me know their version combination please?
Thanks.
pico-20191009 is giving problems with the 1009 build on my T810 too. Pico-20191006 and Magisk 19.4 are doing the trick for me.
Don't know about other combinations
BTW, it's advised not to install the TWRP app as it is known for causing bootloops on this rom.
Don't know for sure, but wiping internal storage before installing rom might be useful too.

mi max 2 and flashed lineage os 16 and was running good until today it bootloop stuck

suddenly today it rebooted and stuck in a bootloop so I tried to enter twrp but was stuck in the twrp logo page, so then after trying to flash multiple twrp files using fastboot, all of them gave the same results. so now I tried to just reset phone to stock rom and downloaded all files and used miflash to flash the rom without locking bootloader and it was a success, but now its stuck in the mi logo and again recovery is not stock, its still twrp and its also stuck in the logo. what do you suggest me to do?

Only Official Binaries can be flashed. Bootloop and Cant get into TWRP.

Hi, I recently thought of flashing Project Sakura or iOS ROM by Sayanu. And when I flashed TWRP I Formatted Data, Used universal forceencrypt disabler, and after booting to phone and then trying to go to recovery, my phone is now stuck in a bootloop and Red Text Saying Only Official Binaries can be Flashed. I went to SamMobile, got the zip file, flashed in Odin, then back to normal, I've reflashed Stock ROM for 7 times straight. Even then, TWRP Fails to load with the red text saying Only Official Binaries can be Flashed. Please help me, I need a custom ROM urgently.

Enable developer mode
Disable OEM lock in developer mode
Read about RMM little bit
Wait 7 days
Flash twrp
There are two encrypted partition the name I forget but you have to reformat it google before procedure
Then format phone
Install any custom ROM that you want
PS project sakura is end of life, lineage 19.1 is pretty stable
