Any reason for why downgrade?
If you made a nandroid backup before flashing dll7 will the bootloader be downgraded also or not?

I agree with you, but if I wanted to make money from it I would not have released the solution public and open, but I do feel credits should be given.
So, would you like to know the answer to the question I asked you, what 0x12345676 in location 0x1002080C does?

location 0x1002080C is s5p_restart_handler INFORM3 aka reboot_mode
reboot fota_bl sets MAGIC 0x12345676
when mach_board_main is executed in sboot and location 0x1002080C has 0x12345676 then it will execute pit_update_bootloader_ota, all pretty simple really.
There is also another special mode of reboot sud which sets s5p_restart_handler to 0xABCF0000 but to discuss its function would be off topic here.

Asked in another thread and got a response from someone saying to get back to stock recovery you "do the same thing you did to get the custom recovery, just use the stock image instead".

Look through QBKings videos found here. Please note, his videos, on the M8, are all listed in the black box on the right.
All of his videos regarding the M8 can be found in this link. You may find what you need in his tutorials.

To unbox:
MOD edit: This thread is for videos on helpful how to's for this device. A unboxing video is nothing more then a review of the device.

Great Information
:good:

I'm wondering if "how to videos" that discuss rooting, custom recoveries, custom ROMs, etc. should also include a warning about accepting OTA updates?
Lots of Galaxy S3 and S4 users unknowingly accepted OTA updates to find their phones were now hopelessly locked down and no custom recoveries could be installed.
I personally believe ALL carriers want their phones locked down securely and do NOT want anyone to be able to mod a phone in any way and with this belief comes the thought that any phone such as the M8 will sooner or later receive an OTA that will lock the bootloader.
A warning about OTAs couldn't hurt anything...

Hi ppl, looking into how to threads, I am still looking for a way to disable SIM from unknown source msg on my m8, how can I do that?
Sent from my HTC6525LVW using XDA Free mobile app

I saw a video about flashing to the Google play version of this device. Is there a link or instructions on here about that? And does anyone know whether it would even work since there's been an update since then?

[GUIDE][HOW TO FLASH LOLLIPOP | SM-N9005][5.0 | N9005XXUGBNL8][Easy]

Confused on how to install Android 5.0 Lollipop? Fear not. This guide have you covered ​
So to start this. We need some things.
Odin
Lollipop Leak
A Backup of your PIT File incase something goes wrong
and lastly a Samsung Galaxy Note 3 THIS GUIDE IS FOR SM-N9005
Now that we have everything we need. Let's start.
THIS WILL ERASE/FACTORY RESET YOUR NOTE 3. So take a backup of your important stuff
Extract the ROM zip file.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Once extracted. Open Odin and set up Odin as follows.
FOR 32GB Model
FOR 16GB Model
Now click START
Once done reboot your device. 16GB users will have to goto Recovery and factory reset
First boot will take longer than expected. Leave it alone for about 10 minutes.
And after some time. You will be greeted with the glorious Android 5.0 screen.
Video Guide. ​

Before flashing we need to make a backup of your PIT file just incase something goes wrong. And to do so open Command Prompt and execute the following commands.
Code:
adb shell su -c "dd if=/dev/block/mmcblk0 of=/sdcard/My-N9005.pit bs=1 skip=17408 count=4244"
adb pull /sdcard/My-N9005.pit
Now that will create a backup of your PIT File as a failsafe. :fingers-crossed:

I've never experienced any issues with WiFi personally. Can you explain more about your issues with it?

Also port for other devices?
Hey,
are there any chances or possibilities for porting this rom also to another device? E.g. the S4 LTE-A, which has "exactly" the same hardware as the note 3 i guess, it also has the snapdragon 800, so i think it might not be too difficult to port this rom also for this device, someone who can tell me something about that?:good::victory:

The fact the Xposed won't work with Android v5.0 at present makes a no go for me. I can't see how I can do without about 6 or 7 key Xposed modules. It's a real shame

So glad to see this Is this leak for the international Note3 ? Does it incluede French language ? Did you see any bug on this leak ? And last question, if the flash goes wrong, how can I use the backup PIT ?
Many thanks for sharing this leak !

I install it on my N9005 it include french and Italian and many other i dont flash bootloader and pit file for now everything it's ok only the WiFi issue!!!i must to put the key wen I restart or close the wireless.

Sorry if is a dumb question, is the first time i try to flash a rom for this device, i have a n900w8 and odin shows me repartitio error, even with repartition unchecked, is ther any chance to install this rom on the n900w8? i think it has the same hardware as the n9005.
Thanks in advance

its not working for note 3 sm n9005

No, I don't think you can flash it, this isn't the same model event if the hardware look same. Maybe a little difference who made ****. But I don't think you can. I'll try it later ^^
A question, @Sewrizer, the wifi patch you give us, we have to pass with a custom recovery ? I don't want to pass my Knox to 1 ^^ I think i'll wait if their is a wifi bug, my wifi code is too long to enter it each time wifi reboot...

This willnot work for the ATT version will it?

Not Working

Quick question:
Can I downgrade to KK? I Want to try this FW but (surely) keeping KK because of Xposed compatibility.
Thanks!!

I'll post a guide about PIT later on sometime. It'll have things like "What is PIT?" "How to Backup?" "How to restore?" "How to revive soft bricked Note 3's" and all. Do remind me after the New Year and I'll make one.

WiFi issue might be solved by flashing this. Thanks @Sewrizer. I personally did not test it and also discourages flashing it as Lollipop includes many new changes to WiFi drivers while the zip file is meant for KitKat. EDIT: Instead of flashing that file. Try this. And also try to move the Q/A's there. Let's try to keep this an organized thread.

Just unlock the bootloader, flash twrp and use the root method of your choice. I recommend magisk.

You'd have to spend $$ to purchase "sunshine" and judging by your lack of experience you could blow your phone up and kill everyone in a 10 meter radius.

You don't need s off to install a custom rom.
Since your rooted and have TWRP installed you just need to download the custom rom of your choice and flash it per the developers instructions.
I suggest @LeeDroid 's rom it's the best of the best IMHO.

Read and re-read the OP carefully and you'll be fine.
About halfway (or more) down the OP you'll see "A quick whistle stop tour of flashing a custom build". It'll tell you how to flash the rom. Search the thread for answers to any questions before asking. During installation of LeeDroid you'll have many choices... choose carefully.

A couple of questions:
Which version U11 do you have?
Do you have ADB enviroment setup on your PC?
If not, You can go to the 15 seconds ADB Installer thread here:

For me ADB is a must.

MAKE A TWRP BACKUP BERFORE FLASHING!​
When a newer version is released the guyz (like Droidit) around there will post download links in the thread.
A must read thread:
[COLLECTION] HTCU U11 – RUU/Firmware/Recovery/OTA/Backups
https://forum.xda-developers.com/u11/how-to/collection-htcu-u11-ruu-firmware-t3612048
A lot of information and helpfull links for how to's... Read and re-read it.
It has a spreadsheet link to "HTC U11–RUU/Firmware/Recovery/OTA/Backups" downloads.
Spreadsheet Link:
https://docs.google.com/spreadsheets/d/15JL3tRWDSVOUKo_revEYtQ_tRcOSJ0vWcvk8a7TK8Hk/htmlview
A couple of questions:
Which version U11 do you have?
Do you have ADB enviroment setup on your PC?
If not, You can go to the 15 seconds ADB Installer thread here:
https://forum.xda-developers.com/showthread.php?t=2588979
For me ADB is a must.
Hope this all makes sense and helps you out.

Thanks friend, I'll try the suggestions
if something does not work out as expected I can use the back up to revert the process and leave the OS as it came from the factory, right?

Yes. You have to unlock your bootloader first prior to rooting but you'll have to pay to have your bootloader unlocked since it's T-mo branded. Here's a link to the forum explaining it:

Let me preface my response with: This is JUST MY OPINION: Just my thoughts/feelings on this
But I wish the Title of this thread stated all the "fyi" stuff. Like if the thread were labeled:
"ROM for T867U when you pay 100-200 for some random dude to "root" your tab, then you can install this Stock Rom with some mods"

A title isn't supposed to be a detailed description. This thread was created off the assumption/pre requisite that you already have an unlocked bootloader, hence the OP. You asked a question, so I provided an option to your dilemma. I did say in my previous post that you have to pay. If you are skeptical on paying for an unlock token, he is a reputable dev. XDA wouldn't just allow some random person to offer a service like this. And if this was false advertisement, the thread would have ceased to exist. And yes, it's quite unfortunate that we have to pay for our Snapdragon devices to be unlocked after all these years of relying on the hard work of devs to exploit, but it's better than being completely locked down. But you yourself can become the change you want to see and find an exploit if this irks you that much. If not, at least be grateful you have a possibility. But enough of this. I don't wish to hijack the thread

Hello. I would like to try this stock ROM Based on T867USQS5CUG1
I have already swapped my firmware from T867V to T867U on boot loader version 5. I did not unlock the bootloader yet.
Seeing as this custom stock ROM is on the same boot loader version 5 would I be able to Flash it via Odin without unlocking the bootloader?
All the best.

Amen brother! Preach it!

Note to the OP...
I see that there may be in incorrect reference to the fact that SAMPWND may NOT be offering the unlocked BL on their site for the T867U... at least none that I can see. I have put out a question to the dev on this.

Any idea if this works on the regular 860 model?

Thanks for all your work on this. It's funny because there doesn't seem to be much work in this device and most searches bring up Tab S6 Lite.
I've flashed way back but since being on Pixels I hadn't seen any reason to.
T-Mobile locks suck but you suggested they're possible after unlocked BL, are you able to point me in the right direction for Sim unlock? The hardware is nice it's just a shame it's locked and has so much bloat.
Thanks again.
