N900W8 Downgrade to 4.3

So I flashed 4.4.2 successfully and it was booting and everything was working. Now I'm trying to get back to 4.3 but I am unable to do so.
In ODIN, I selected only the 4.3 AP file -
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
It just keeps trying to boot for a very long time. What am i doing wrong?

The 4.4.2 bootloader would stop you from downgrading, in other words, you 'CANNOT' go back to 4.3. You have to use 4.4.2 mate.

Okay, I know normally, 4.4.2 bootloader stops you from downgrading to 4.3. Maybe those people didn't flash the 4.4.2 bootloader. Anyway!
Then maybe you need a factory reset. Do in stock recovery (It will delete all files in internal sd).
Better still, maybe flash custom recovery then Wipe there and not lose files in Internal SD. Cheers!

Are you running a custom rom right now? If you are, follow the steps below;
- if you flashed a custom rom ( x-note, omega, etc...) after flashing stock firmware, you have to flash back to stock KK same way when you upgrade
- flash your original 4.3 firmware, for example in my case I have MJ4 before flashing then I have to flash MJ4 back because MJ1 will fail.
- if after flashing of original 4.3 firmware and it's getting stuck at the samsung flash screen, take battery out and put it back in, boot to recovery ( press vol up + power + home button at the same time till recovery appears then let go ) and do factory reset then reboot and it should boot up all the way to setup
edit: I haven't seen your last post below the picture, in this case just reboot to recovery and factory reset and it'll boot up all the way to setup.

Lucky Users of Canadian version. It seems no other version can revert from 4.4 to 4.3 OR 4.3 to 4.2.

Now i have found that device not only stops at logo (security error) on hard reset but on restore personal data from original rom backup and on sim remove/ insert or trying to change any file of system!:crying:
I followed the following flashing procedure, just done full wipe, then flashed the rom and flashed update supersu 2.01. that is all!

I did basically the same thing and I have it working now. However the knock on is still a pain in the a$$ and there is still the dead spot in the upper part of the screen. It was not there before kit Kat.

Please also help me !

Same problem for me after flashing lamhoang 1.5 (back from Lamhoang Final ART).
However, I factory rest it (using hard button) and enter recovery, reflash lamhoang final again.
It works!

Can u get the phone back into recovery mode? With the phone off, press and,hold the power and volume down button. When the LG logo appears let off the power button and quickly press and hold again. The screen should turn white and will ask if you want to do a factory reset. Choose yes and you should go into recovery mode. Hopefully you can get that far. Then you can reinstall from your backup(if u made one) if not. Be sire you do a wipe. Also if you unzipped the file into multiple folder you can have problems too. If so flash the backup and delete everything except the zip file. Once you are in recovery wipe the data. Be sure to include dalvic cache and cache. Then flash the cloudy Rom,zip file and all should be good. Pm me if you have any questions about it.

Thanks for suggestion!
But i always go into recovery, do a full wipe (dalvic cache, cache, system and data)!
But the problem of security error is always there!

Flash a proper kernel for it to run.
Ask in his thread, that's the best.

You need to flash Kk_baseband for your device

[Q] Flashing 4.4.2, or Custom ROM?

Hey Y'all,
So I've been trying to root my 5.0.1 S4, but could not do it for the life of me. I figured since the CF Auto Root file was made for 4.4.2, I would try flashing back to that with Odin. After getting the correct build for my device, I've been trying to get it to flash, but it got to system, and then stalled forever. I let it run overnight, and it hadn't progressed, so I tried restarting. Now, it fails in a matter of seconds, but I keep seeing progress on the phone's blue bar.
[Q] AM I wasting my time trying to flash an old build? If so, should I just use a custom rom so I get my root? And if so, which one should I use (I'm new to this phone mod stuff.)
Thanks in advance!

Yes, stop before you brick your device. CF Auto Root works for Lollipop. Or Odin TWRP and flash SuperSU zip. Or just flash a rooted ROM. Read the OPs and decide which one sounds like the best fit for you.

KK, thanks. I could not get CF to root my device, trying 3 different versions of Odin. I'll go the custom rom route, methinks.

Uncheck Auto Reboot and F Reset (everything) when using Odin. And wait a minute after it says PASS before unplugging. Also try different ports and cables.

I can only find .img files for TWRP, I haven't yet been able to find any .tar files. Any tips on where to get a recovery file to use with Odin?
Yeah, definitely cannot restart my phone at the point, it's referring me to Kies to recover. Kies won't connect, either 3.0 or 2.6. So At this point I guess I'm hoping flashing a custom ROM will work...otherwise, is my phone bricked?

TWRP can flash images now.
Flash this build of TWRP first. (It's a .tar for Odin)
https://dl.twrp.me/jfltespr/twrp-2.8.4.0-jfltespr.tar
Copy this build to your device somewhere. (You might as well go ahead and copy a ROM you want to install on your device also.)
https://dl.twrp.me/jfltespr/twrp-2.8.7.0-jfltespr.img
Boot into TWRP and go to install. Select images button at the bottom right and select the build you copied to your device. You will now be running the current version of TWRP.

WOOOOOO!
After a ton of troubleshooting and grief, I finally got 5.0.1 back on, and working. I also discovered that my front usb port was not working correctly. I guess I'll try to root it now!
Aaaaaand, it seems to have worked flawlessly. Thanks for all the help guys!

Little Help needed to get my 6p alive again

please help me.
I have completely wiped my device. nothing is there in internal storage. Just the TWRP folder.
it has unlocked bootloader and twrp installed
but it is the unrooted device.
so please tell me what is best for me?
shall I root it or can I directly go to stock Oero?
I have already downloaded stock file '8.1.0 (OPM6.171019.030.E1, Jul 2018)- angler-opm6.171019.030.e1-factory-1abcb2f1.zip'

You will be fine I wipe my internal from time to time. Just make sure you update your bootloader and vendor. If you use the flash all I'm pretty sure it's done for you but if using fastboot method follow the steps in the hiesenberg guide. Just so you know once on the latest Oreo builds from what I've read can no longer downgrade. I haven't verified or read up on it myself but maybe look into if you think you might want to go back to nougat .

i have tried that earlier, but still i got the red triangle.
since i failed to go to stock today i installed latest twrp-3.2.2-0-angler using latest SDK tool.
then i flashed Magisk-v16.0 and then ResurrectionRemix-M-v5.7.4-20161008-angler and it immediately went to google logo and stuck there.

just use this to get back to stock https://developers.google.com/android/images
all you do is boot in to fast boot plug into pc and run flash all
there are ways to save data but you already wiped so no need
if your still confused just look up a guide of how to flash factory images and install the usb drivers

It looks good but didn't seem to flash radio and bootloader maybe just not in screen shot should boot but if it still won't boot in to the stock recovery and factory reset might help

You could have the bad big cores try flashing one of the 4 core fixes. Also I wait to flash magisk until after first boot. It can hang you on the Google screen .

Galaxy J5 SM-J500FN stuck on boot screen after flashing custom ROMs

Hello to everyone,
I hope that someone can help me at this point where i'm stuck on bootscreen after i flashed an custom ROM.
So, let me tell you my story.
I have a little of experience with flashing custom ROMs. And on my personal phone (Galasy S5) i succesfully installed over and over again custom ROMs. I really like the ROMs from AOSP Extended. They are covering all of my needs. So today i have an Samsung Galaxy J5 SM-J500FN. It is having some problems with the capacitive buttons(Back and multitasking buttons); those are playing however they want, so you can realise that entering in some app and your phone exiting fro it by itself is very annoyng. So on my S5 i have an option that can disable those buttons for good. And i wanted to install the Android &.1 Nougat offered by AOSP Extended today. So i ve got the TWRP from the official website for the right model of the phone (J500FN) and put it succesfully on it. I downloaded the ROM from official AOSP website, and succesfully installed it on the phone whithout any error. Then i installed the GApps nano, again with 0 errors. And when i was relaxing a little bit hoping that everything it s allright, when i wanted to boot up the phone, it froze up at boot screen (At the moment with that logo with Samsung ... powerd by Android). Then in a couple of seconds it started to turn to an green screen and then to an white screen. At this point, everything is frozen. So i removed the battery and entered in recovery mode(TWRP). There was no problem (only with those capactive buttons that i want to block).. But anyway, i donloaded several ROMs and nothing so far. I tried with anoter TWRP version, samething, stuck on boot screen.
Until my first atempt to flash the custom ROM, the phone worked just fine, only that those buttons ware going crazy. But now, i can't start it up in every mode i can think of.
Can anyone help me with this, please?! Any ideea of how to slve it?
TWRP version 3.1.1-1 j5 nlte
Firmware version: AospExtended-v4.5-j5ltexx-20170816-2007-OFFICIAL
Phone version: SM-J500FN
Tried with various TWRP versions and ROMs. Installing with and without GApps. All the results were the same like in the pictures below:
1) Start up like a normal Android phone

}
2) The the big surprise
3) Getting colorfull
4) Advancing...
For now, i can flash with Odin any version of TWRP, i can flash from TWRP any firmware, but i cannot get it boot up normally.
I don't have any backups from stock firmware so, please don t ask me about that.
Thanks in advance...

Look at the aosp file you downloaded. It says j5LTE.
Your device is j5nlte not j5lte you tried to install the wrong file.
Simple as that.
And if that isnt your problem you may have the wrong bootloader and modem but changing that is easy just follow the guide here https://forum.xda-developers.com/ga...5-1-1-bootloader-modem-j500xx-t3566801/page15
