Bootloop after flashing twrp - Samsung Galaxy A40 Questions & Answers

Hi xda,
I'm new into the world of flashing so any help would be nice.
I used this tuto:
https://rootmydevice.com/tutorials/root-samsung-galaxy-a40/
and downloaded twrp image from this post:
https://forum.xda-developers.com/galaxy-a40/development/recovery-twrp-galaxy-a40-t3968586
After flash phone restarted as intented but it keeps booting, I tried also some methods how to enter recovery mode while bootlooping but they didn't work out. I also want to flash pixel experience rom.
Thanks for any help provided.

Use the TWRP from this thread.
Your TWRP is not working anymore with actual firmware.

Trouble reflashing ASUS stock ROM for ZE551KL

I accidentally tried doing a factory reset, and flashing an incorrect rom. So I lost the stock rom, and have no other rom to use. I tried using TWRP to flash ASUS's stock firmware from asus's support website, under firmware. Using firmware file: "UL-Z00T-WW-1.16.40.763-user.zip"
but TWRP tells me "E:Error executing updater binary in zip '/sdcard/TWRP/Stock.zip'
Error flashing '/sdcard/TWRP/Stock.zip"
I still have access to both adb, fastboot, and TWRP but I cant get an OS to install.
Any help with this would be greatly appreciated, haven't even had this phone a day yet, and already may have broken it.
I don't have an answer to your question , just got this phone yesterday and am in the process of figuring out how to root and install a custom recovery for this specific device.. I have found many methods to root but none for my specific model. I think you have the same model as I do and was hoping you could lead me to the place that will give me the files I need.. the box my phone came in has the model as ASUS_Z00TD (ZE551KL).. Sorry I wasn't of any help to you, hope you manage to figure out how to flash something that will get your device running again!

Do yo mean this stock recovery? http://forum.xda-developers.com/showpost.php?p=64441364&postcount=9
How do I flash it? just "fastboot flash recovery stock_recovery.img" ?
If so, I've tried that, and TWRP still boot when I try to enter recovery. Also, once I've flashed the stock recovery, do I just place the firmware on the root of the sdcard as 'update.zip' and try to install it from there?
Thanks for your help already, and sorry about the repetitive questions!

Yes. You installed official twrp 2.8.7.0?? I didn't try updating twrp through twrp. If I did I could've provided assistance.
I can't take anything easily, so if at all I have something new to do, I'll start from the beginning. Lol.

Help needed. Urgently

I had installed cm 13 and tried installing a new kernel but i guess since i was on a old version it didn't work out. So i proceeded with putting the old kernel back *sandy kernel* however now when the phone opens up i put my pass code it shows the background for a split second with a system ui crashed error and back to lock screen. hence i tried installing a recovery again (twrp hybrid) since the latest roms use that and I wanted a new rom anyway. But i thought id back my stuff up but alas the system ui error doesn't allow me to do so. Finally i ended up by using fastboot to flash the new recovery but even after it said OK ! my phone won't boot into recovery.
So now i am stuck with a OP2 that boots into cm13 but cant get past the lockscreen, a recovery that won't load and a fastboot mode that is the only working thing.
God I really shouldve backed it up i know. But is there a way I can resolve this without losing my data?
I have an exam and the notes are in them.
Help is appreciated !

As I said. the method i showed you is most certainly the solution. But you need a Computer and yes, 1gb is propably too much for mobile data
Maybe, just maybe if you flash OOS-Firmware it might help. But i dont know for sure.
So i finally managed to get into twrp 2.8.7 (lollipop)by this http://forum.xda-developers.com/devdb/project/dl/?id=16684
thanks a lot for all your hard work guys ! (cant boot into os still but twrp will help atleast)

NO Recovery in my phone, Bootloader Unlocked (OP2)

Few day earlier my home button died , so i decided to change rom . After some tries with different roms it started to work again (finally settled for oxygenos) . I used that rom for quite some time before i got bored of oxygenos and decided to change it . But to my surprise i won't boot into recovery no matter what i try. I tried to upgrade or change it using flashify and other app ,still nothing happened. Finally i tried to flash recovery using computer , still it won't boot in recovery .
My boot loader is having unlocked status. I tried flashing different types and versions of recovery . Everytime i write command error comes and it won't flash . I searched my threads with suggestions of using specific recovery for oneplus 2 but none of them works.
Please help , My battery drains like sand from hand. I get less than 2.5 hours of screen time

Oos 2.2.1
Ok.. Go into Fastboot mode.. If your bootloader is unlocked, flash twrp recovery 3.0.2-0.img.. You can download it from twrp website.. Hope you know how to flash a twrp recovery.

Tried it but doesn't work ....
Some TWRP recoveries don't work with earlier rom firmware. Try finding Twrp 2.8.6 or 2.8.7 and try flashing. Also wich version of windows are you using. I've had my fair share of problems with windows 10.
Best of luck

When Android Keep Booting Into TWRP Recovery

Thousands of android users having this problem, when you install custom ROM and then you try to reset your phone; it keep rebooting into TWRP recovery (not system), even after you flash your ROM again.

The answer for me when I had this happen in September was to simply flash the Magisk zip file from the TWRP recovery after one of the many loops that it had done
(and I had tried everything else - reflashed TWRP from both fastboot and recovery many times, re-flashed the Google Pixel full image via the flash-all.bat file a few times, etc).
