[T-Mobile Galaxy Note 4 General] AlkaliV2:
The reason OTA and Kies don't do the reset themselves is because they aren't capable of backing up the data you've accumulated on your phone since you've owned it. The average user only get an icon in the upper left-hand corner that tells them to update and they do it because T-Mobile says so. Imagine that same user installed the update and then they were looking at the Lollipop welcome screen like they had just taken the device out of the box. It would lead to an outcry from consumers because they lost months of data from the upgrade. However, we here on XDA are not average users and some of us know exactly what happens during these updates. You probably don't remember this, but there was a time when Odin wiped your phone automatically even on incremental updates. Because just like flashing a ROM, clean is the only way to truly ensure that residual files are not causing problems. But they eventually removed this behavior in later releases of Android. I don't know why this was done, I am only able to tell you the history of Odin as I know it. However, because Android changes have been so drastic lately (locked SD cards, addition of preload partition, removal of preload partition, SELinux policy updates, institution of Knox and protected files, etc etc etc.) not starting with a clean slate led to a myriad of problems for users. If you need specific examples just look at the Galaxy S5 Wi-Fi issues from taking the Lollipop OTA without doing a factory reset. If you format your hard drive before installing a new version of Windows then you should be capable of understanding why clean partitions for an OS upgrade makes sense. But you don't have to take my word for it, click the link I left with CtSomethingOrAnother up there. People almost unanimously support a factory reset for major upgrades. So you can take my advice or follow your own, but I promise that I'm going to get plenty of sleep tonight regardless of what you decide to do with your phone. You have to realize that I am giving advice as a senior member of a respected development community where new members come for answers. I make sure that I am giving them the best advice that I could possibly give them with my experience on these forums and with Samsung devices. If users decide to cut corners after knowing the proper way to do it, that is on them.

tl;dr -- I wrote this Howto so that I could help people; not waste their time. You don't have to believe anything I wrote above. In fact I encourage you to research this information yourself and come to your own conclusions about why factory resets are necessary. Until Google goes on record saying, "No more factory resets for upgrades" I'm going to keep my advice just the way it is written.
[T-Mobile Galaxy Note 4 General] KingBeef:
I appreciate you taking the time to explain this. I have been flashing and what not for a few years, but I am by no means completely aware of why I do things a certain way in all cases. It is nice to know the "why" behind things sometimes.
[T-Mobile Galaxy Note 4 General] CtJackHarkness:
I think resetting the phone and having everything wiped should only be done if experiencing problems. Everywhere online this is the case. It is NOT required to wipe a phone. And again if you wipe / factory reset a CDMA phone - don't they have you call in to reactivate it? (little offtopic but just curious regarding verizon)
[T-Mobile Galaxy Note 4 General] AlkaliV2:
To me, the why is always the most important part. When someone posts a flashable file to fix a problem I open it up to see what it is doing. It took a lot of reading and some prior experience with Linux to be able to grasp a lot of what Android developers are doing when they change the files

I truly don't understand how you could acknowledge that skipping the factory resetting could lead to problems for people but that you don't recommend it because people should just use it until they have a problem and then wipe all their data at that point. And as far as "everywhere online this is the case", I literally Googled for you tons of links with people saying to factory reset for Android upgrades and you're choosing to ignore the information. That's on you. As far as CDMA phones having to be re-activated? It's been years since I used a device on Sprint and doing a factory reset on Android led to the device activating itself. It isn't an issue, it's just part of the setup process. It's no different than updating the PRL and Profile on Sprint (CDMA) once a month to ensure roaming capabilities are working at peak efficiency. Verizon customers used to have to dial a number to update the PRL but now on Android it happens in the background just like it would during setup.

However, changing your mind isn't my job nor is it how I intend to spend my time on here. You can do whatever you wish with your phone and what I wrote is exactly how I handle my phone. I'm leaving your criticism and my responses in this thread for people who want to hear both sides and hopefully that will accomplish what you set out to do by posting here in the first place. If you still aren't satisfied, please take it to PM.

EDIT: Nevermind, I went back and edited the post to clarify that boot loop happens on downgrading and encouraged people to wipe user data while upgrading.
[T-Mobile Galaxy Note 4 General] hacker904:
This method worked for me..

This was my solution to completely downgrade the N910T back to KitKat after a full Lollipop stock upgrade or rom.

Please do a nan droid back up before attempting this first?

*** I am not responsible nor accountable if you damage your android device when done incorrectly or attempting this***

Please understand doing this will and is going to trigger the knox count if attempted.

When I did this it worked for me to test Lollipop or roms and back to KitKat stock for example:

DARTHSTALKER_NOTE4_V2

InfamousROM_Note4_COD6_v1.8.1.

Just to name some good KitKat and Lollipop ROMs for the N910T that I use.

Four things your gonna need before you start:

1. The actual KitKat N910TUVU1ANK4 Firmware.

2. Odin3 v3.07

3. N910TUVU1ANK4_N910TTMB1ANK4_TMB-files-modem.bin-boot.img-recovery.img (This contains 4 files: boot.img, modem.bin, NON-HLOS.bin, recovery.img).

4. WinRar or 7zip software.

What I found is that the baseband changes and does not allow to downgrade from stock N910TUVU1COD6 Lollipop back to stock N910TUVU1ANK4 KitKat with Odin it just wouldn't allow it. I've done this so I know this works since I wasn't ready for Lollipop bugs and battery consumption. From what I heard this couldn't be done.. Anyway after your nan droid backup Wipe every thing in your recovery TWRP: Advance wipe, Wipe the dalvik cach, System, Data, Internal storage, cache reboot back download mode. Now take the TMB-files-modem.bin-boot.img-recovery.img extract it with winrar or 7zip. Now go back into Odin Click Phone and search for the files you just extracted. They are 2 files needed and that's the NON-HLOS and the modem file. This needs to be installed one at a time on the Phone tab using Odin. Flash the NON-HLOS and reboot back into download mode. Now flash the modem file in the Phone tab using Odin and boot back into download mode. Now flash N910TUVU1ANK4 KitKat Firmware using Odin and let it finish and reboot completely. Check and make sure that Odin completes the flash and reboot completely to Tmobile setup screen. Done..

If the firmware feels weird at first just do a factory reset and cache in the stock recovery. Hope this helps out the XDA community. Don't forget to thanks please?

I'm going to wait on some testers for this one lol but if confirmed...I'm on it! Lol although I'm a little confused why I would nan and then immediately wipe internal data? I don't have a SD card yet though (just got phone today) so any nan I make goes right to internal :/
[T-Mobile Galaxy Note 4 General] hacker904:
Internal data

I wouldn't recommend doing any type of internal data wipe unless you have a SD card. Now take note of this when using custom (TWRP) recovery that you have to manually go into storage during the back up. Now go to the drive/storage and change the option in oder to back up on the Ext.SD card. I would be careful in the recovery when advance wiping the phone to reinstall another rom. It has the option to wipe the Ext.Sdcard...Do not do that take it from me I've done it rushing and it sucks. TWRP backs the nandroid on the Ext. in a TWRP file.

Hope this helps every one out.

Please thank?

[T-Mobile Galaxy Note 4 General] lewis.james.750983:
I guess tmobile changed some security policy that blocks phone users from downgrading.

Has anyone confirmed that you cant downgrade from Cog6? I am on one of the 5.1.1 ROMs I tried downgrading to 4.4.4 using ODIN but it keeps failing. Has anybody had any success with this?
[T-Mobile Galaxy Note 4 General] Some_dude36:
When upgrading from 4.x.x to 5.x.x do I need to download and install the official ank4 first if im already at 4.x.x rooted ?? Or can I download and odin the official 5.x.x cod6 and install from existing ank4 ?

in short

Rooted 4.x/heimdall/stock base ank4/stock base c0d6 5.x ( or OTA official update from stock base 4.x ???)/ twrp/rooted 5.x ?

or

rooted 4.x/heimdall/stock base c0d6 5.x /twrp/rooted 5.x ?

Thanks

[Sprint  Galaxy Note 4 Themes and Apps] Sterist:
I have been getting a problem with voicemail (visual voicemail, "vvm") nagging about a required update while unable to do so with a "General Failure" error. Google search revealed many of the same issue for other devices but didn't see any for this device.

I restored my stock rom backup, updated voicemail, backed up voicemail, and restored custom Rom. I can confirm that simply installing this voicemail will solve the issue (for now) until another required voicemail update is pushed OTA.

this is comes from STOCK SPRINT NOTE 4 N910P KITKAT NIE rom, it should work on any KITKAT rom for this device.

it MIGHT work on lollipop for anyone using that and having the issue too though you should use titanium backup to save your old voicemail beforehand, since uninstalling the update "restoring factory version" may also delete all your voice messages.

it also MIGHT work for other U.S. variants of the Note 4 but that is your risk to take.
[Galaxy Note Pro 12.2 Accessories] petercohen:
Hello, I have been using the SanDisk Ultra 64GB. Whenever I clicked on the stock camera app, there was a pause before it was launched. Sometimes it seems that after I chose the video/photo, there was a pause as well. I wonder if I would have these problems if I use the SanDisk Extreme PRO® microSDXC UHS-I Card 64GB card. Any user experienced appreciated. Thank you.

P.S. I set the saving to the sdcard by default.
[Galaxy Note Pro 12.2 Accessories] ShadowLea:
Simple way to test: Does it also happen when you take out the SDcard, forcing it to use the internal memory?

The answer is probably yes. Samsung actually made it a point to mention that the S6 camera launches much, much faster than on existing devices, leading us to believe the delay is normal. As for the delay in opening the preview: It opens the Stock Gallery. That poor thing is bloated to a point where it can't launch quickly even on an empty device.

[G3 Q&A, Help & Troubleshooting] jreink01:
I know this should be directed to the twrp forums but I wanted to get feedback from owners of the sprint lg g3 preferably using the CM12.1 android version 5.1.

I have always had this issue where I am unable to flash roms on my external sd card via twrp. Everytime I try (just tried again tonight), after over and hour of restoring, it was only at 10%. When I flash the same rom on the internal sd (memory) it only takes about 10 minutes to accomplish the entire restore, its the same way for backups too. I don't understand why I am unable to do backups and restores from my external sd. It is very inconvienant to keep moving the backups from external to internal and vice versa. Plus, I can never put more than 1 backup on my internal because they take up so much space (roughly 8gb). It doesn't matter what backup rom I flash it does the same thing. Has anyone else been able to flash roms from their external sd card and if so, what did you have to do to get it to work? I have sent my concerns to the twrp team with no replies back. I am just curious if others are having the same problem or if their has been a fix for this.

I am currently on version 2.8.5 of twrp.
[G3 Q&A, Help & Troubleshooting] jreink01:
Does anyone have any suggestions or feedback on this issue? Thanks
[G3 Q&A, Help & Troubleshooting] Redline:
Hey mate,

You could try installing the TWRP version for the G3 from their app, rather than just the generic version for any phone. If that doesn't work, then it sounds like your SD Card could be corrupted. I backup my whole phone to my external SD Card before I flash any updates or anything else, and can install the ROM updates from my SD Card with no problems whatsoever.

All I can really think of is either a new SD Card, or the official TWRP for the G3 from their app.
[G3 Q&A, Help & Troubleshooting] jreink01:
Thanks for the response. Do you have a G3 also? I have installed the official bumped version of twrp for my sprint phone and am still having issues. Just by curiousity, when you are in twrp, are you able to backup and restore directly to/from the sd card. I do not have any issues with my card other than this, I can transfer and move files, etc. I have noticed though on my 64 gb scandisk card that when it first boots up, it will say not able to retrieve location. I put a different card in the phone and that message stopped which makes me believe it has something to do with the card. That location message just started about a month or two ago.
[G3 Q&A, Help & Troubleshooting] jreink01:
It turns out that it was something to do with the external SD card. I replaced it with a brand new card and i am able to backup and restore to/from the external card with twrp.
