[Q] Problem installing Darkys rom

Hello,
I have tried installing cyanogenmod. This worked, but I wasn't happy with it and tried to go back to darky's rom, by wiping to factory defaults, then wiping all data; and afterwards update to darky's rom.
But somehow, my phone isn't starting anymore. I also cannot go into Recovery mode. The only thing that is starting is Downloading mode. How can I get a decent rom installed again? :S
Pls help! I don't know what to do anymore
Can anyone help me out here?

[Q] Getting back to stock

I was wondering a few things if anyone could help. I have the metro version
of the mega. Id like to know if it is possible to get back to complete stock. I flashed
twrp, which is awesome. Also I bought a sd card reader from Walmart so
I can add and remove files to the sd if I ever brick the phone. I have
tried cm11 wasn't for me. I have rooted the phone etc. I'm trying
to get back to the state of when I first got the phone. Currently I flashed
bnb's clean twrp files and am back to stock. I want to get rid
of twrp and go back to thr original bootloader if theres
a way. From what I know the bootlaoder is locked up.
Im thinking about taking the phone back to the store as the
owner knows exactly what I'm talking about when I start grilling
him with questions about different roms and such. Do you
think at the store they may be able to reflash it? I've
tried via odin, but can only flash the twrp and then from there
I am able to flash the clean backup. I totally want to go back
to original. If you guys have any tips, questions or comments
please and thank you.

Galaxy Note 2 Simple Mobile/Verizon Rapid Bootloop

A couple of weeks ago I bought a Galaxy Note 2 from Simple Mobile began to experiment with it. Later on I managed to root it, but I accidentally flashed a recovery via Rom Manager which after a restart broke my phone.
After that I flashed a OTA through Odin of Verizon 4.1.2. The system booted and everything but the radio was missing meaning that I could not text or use 3G. I looked for many ways to restore it but none worked.
I later on flashed a T-Mobile ROM thinking it will help restore the radio and it did successfully flash the ROM through the recovery. But the ROM turned out to be 4.3 and the radio still didn't work. Later on in the same day I flashed an OTA of T-Mobile through Odin and that's when this happened. My phone bootloops really fast when I turn it on. The recovery doesn't show up at all. And every time I flash anything through Odin it fails. I've felt ashamed all this time and it took me a while to reflect and face what I've done and decided to post on here to get help.
Thanks for reading! Any help is appreciated. I will try every method that gets posted and will post back results.

I have a very similar problem. hope you get help on this, I have been trying to fix this problem for a month.
The 4.3 update is where the issue came from if it will allow you to flash try using a custom rom to get you out the boot loop but because the 4.3 bootloader is locked you now have another issue you will now have to run a virtual rom and there is a certain way you have to do it or you will completely brick your phone try researching first Google your phone model with the rom build 4.3 root you have to root it now before you can do any modifications at this point

bootlooping after flashing twrp, need help

hey folks, yesterday I was trying to root my phone and something went wrong and now it is bootlooping. I spent the last hour researching and couldn't find a solution, and I really can't invest more time into it right now. I can give a few bucks worth of bitcoin to any good soul that helps me save my phone.
So, I have a S9+ (was) running pie, japanese version, SCV39 (snapdragon) which I think that is the same version as G9650, this may be the source of the problem.
I've flashed twrp star2qltechn on it. After it, I flashed no-verity-opt-encrypt-samsung and magisk. And the phone was stuck bootlooping.
Without knowing what to do I wiped all data and flashed a new stock ROM on it but it keept bootlooping.
Details: I may have flashed and old version magisk but and after I've flashed magisk 18.
I was in kind of a hurry because I use Mac and had to ask my sister for her PC, and she got to get back to her home. I got an old windows laptop to try to fix this problem.
Thanks in advance.
For reference: I was able to recover my phone by wiping all data on the phone thru twrp and installing this ROM: https://firmwarex.net/samsung-s9-scv39-9-0-official-firmware-rom/

Help!! Galaxy Tab S3 stuck in bootloop. Needs reflash with CSC t820xxu2brl2

Hi All,
Noob here. I've reflashed older Galaxy devices to LineageOS with no issues, but I'm worried I've bricked my Galaxy Tab S3. I flashed TWRP no problem, flashed Lineage OS and Gapps and rebooted, but it got stuck on the LOS boot screen. I thought I'd re flash the original firmware, but it lists the target as t820xxu2brl2. Looks like the CSC code to me, and this doesn't seem to exist at all to download anywhere. I'd like to install LOS, but would happily revert to stock just so I can use the thing again!
I don't know if:
I have to re flash the stock firmware
or
I'm missing something that will help LOS boot loop issue.
If anyone has any ideas, I would be grateful. I've alread lost 3 days of my life trying to sort this!!
Thanks!!

Reflash LOS. Maybe you have to do a factory reset. If you have a backup of all your data.
Flashing back any recent stock firmware for your device and region should work fine too.
