Bootloop after first restart with multiple CFWs!

Hi guys,
I have the standard note III 9005 and I had always installed CFWs on it.
I wanted to update to newer 6.0.1 Roms (had 6 roms before) but I seem to have a VERY annoying bug:
I tried to install Temaseks rom and resurrection rom but I had huge issues with it. I got bootloops although I got the newest 3.0.2.0 Team Win Recovery Project
I installed rom, GAPPS (correct version of course 6.0.1) , install rom again then delete cache and then it worked on both roms.
So a simple "install rom, GAPPS, then clean cache" didnt work. I tried to install multiple times until I got the installation! YAY! BUUUT!
Here is the fun part:
If I restarted the phone acidentally or on purpose I got stuck in a bootloop. After that the phone was unuseable again so the installation was useless.
Only solution is to completely wipe and reinstall and experiment with the order of installation until it works!
I did install STOCK rom because I was so freaked out and then went with ODIN the complete rooting guide for clean rooting, but still problem exists.
I tried two other roms but the problem was that while flashing the phone restarted automaticly and then TWRP said no installed rom? ???
Huge thanks for helping me!
New info:
I was able to make the rom work. I restarted and got stuck into bootloop!
I could boot normally after deleting dalvik cache!
But after rebooting I got into bootloop. Tried deleting cache again but this time it never booted properly.
How can I avoid by always deleting dalvik whenever I have to restart my phone (if battery dies or purpose)?
PPS: Stock Rom flash works flavlessly. I am waiting in stock rom until I find a proper solution :"(
Suggest you read the roms faqs and Q&A particularly with regard to TWRP .

Stuck while flashing Rom zip [solved]

I officially upgraded to 3.0.2, unlocked and rooted my phone.
It was fine for the first few times I flashed multiple ROMs. But ever since I flashed Exodus, I keep having issues switching to different ROM.
A week ago, I flashed "Switch to OOS3_H2OSMMv7" zip and was able to flash Resurrection Remix, but today when I tried switching to CM13 or PA it gets stuck at flashing the ROM zip. I tried flashing the firmware zip again and flash the ROM, but to no avail. It won't flash any ROMs now, just stuck at recovery while flashing the zip.
I have a working fastboot and recovery mode though, so I'm trying to avoid flashing the entire factory image but that seems to be only option left. Does anyone have any clue as to why this is happening and how I can fix it?
Edit: Resurrection Remix gets installed fine, CM13 and PA still giving me issues.
Edit: I downloaded the latest version of CM13 and it works. Earlier I was using June 30 build which seems to have issues with the new firmware. I'll try out the new PA build to see if it fixes that too.
What error does your recovery gives?
Do you have Data Backup?
Can you access ADB while in Recovery?

It does not show any error as it just looping while installing the zip. I have to force shut down the phone to exit it.
Yes, I have backed up all my data
Yes, I am able to access my phone in both ADB and in fastboot modes.
After flashing Custom ROM, Wipe data, cache, d-cache and then reboot.
If still doesnt work try flashing another custom ROM. You can use adb-sideload to flash another zip in recovery mod.

(sovled)Bootloop after installing custom rom in TWRP in Z00LD HELP!!!

i had installed custom rom and recovery(lineage 14.1 & twrp)
it was working fine until the lineage updater downloaded an update and asked me to install it.
but i didnt read the instructions properly and now every time i reboot my Z00ld it gets stuck in a bootloop
how can i get out of the loop.
here are few things ive tried already:
i had a backup after installing the custom rom (the 1st time), the backup didnt work.
so i wiped the whole OS and tried to install the rom again. it completes the installation process without any errors but after completing, it just boots back to the TWRP recovery.
How am i supposed to get out of this loop.
(this happened only after the updater downloaded an update and tried to install it. )

Lineage seems to be no more available for Z00LD. I'm trying to install any custom roms on my Z00LD (I'm new on rooting and/or installing new roms) but I am not sure about which one is available for that model. Could anyone help me please? Thanks.

Galaxy A5(2015) restarts again and again.

Hello, i wanted to change frequency bands on galaxy a5 and use this thread:https://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059, after i restart device, it started but after few seconds it restarted automatically, after started and same.
what can i do, if i install stock rom may it back to normal(after hard reset from twrp, and install custom os nothing changed)?
Can someone help?
Clean wiping and installing stock ROM will obviously fix this issue. If you are on a custom ROM, you can try wiping and reinstalling the system partition only which may fix the issue of boot loop.

My oneplus 5 does not recognize rom stock!!

I'm using the xxxNolimits rom 5.1.3. When I try to do the procedure to update the version of the oxygen I can not. I downloaded the rom from the site of oneplus, 5.1.4, I make the flash in the TWRP blu spark latest version and when I reboot the message "no OS installed"
I do not know what to do, my oneplus only recognizes the custom rom if I try to go back to the stock it does not recognize. It's like I'm not flashing anything. MA does not appear any error during the flashing of the stock rom by twrp
Have you wiped data? You can't upgrade from xXx to stock OOS without wiping data. Try wiping data, system, flashing OOS, rebooting and if it starts, reboot back to recovery and flash kernel ?
