All,
When I worked on my wife's new phone, I did a full restore from Titanium backup and that caused a number of problems with the phone. For example, I wound up losing Gallery along the way. In an attempt to repair this mess, I followed the published factory reset procedure. However, this does not do a true factory reset - it only wipes SD card data and a small number of settings.
Is there some way to truly reset the phone to the state it was in when I took it out of its box? If so, please provide some guidance.
The phone is question is a Sprint phone, SM-G900P that originally had Android 4.4.4.
Thank you.

Detection - thank you. The methods shown are the one's that do not accomplish what I want - they simply reset certain parameters, but do not restore the original software. The Q&A mentions recoveries - I think that that may be what I am seeking.

Ah I see, in order to restore the original firmware, you'd need to use ODIN with a stock ROM & the PIT file, that will (should) completely delete and recreate all partitions, then reflash the original ROM
You flash them both in ODIN at the same time, PIT into PIT section, ROM into AP/PDA section
Flashing a custom recovery can also achieve this, but you will be left with a custom recovery, not stock, until you reflash a stock ROM
I'm on the same boat as you. We need to install Samsung's stock firmware.
Update firmware through Odin
Firmware update through Samsung
Install Kies
Upgrade firmware
Hope that it worked
Go check if it worked ( Volume up/ Home button/Power button )

i am really new to rom flashing, but really want to get good at it.
thanks everyone in advance,
ths forum is amazing, and all you people are amazing.
Samsung devices are pretty easy to restore and hard to brick, as long as you have some firmware you can flash through Odin. Download mode should remain intact even if you mess up the bootloader/system.
I haven't looked at the link you provided, but assuming the downloads there are in Odin format, flashing back to stock should be easy as pie.
If however, you don't have Odin flashable firmware, and you ahve soemthign that needs to be flashed via fastboot/recovery, then I'm hoping your recovery is still intact and you can boot to it via Volume Up + Home + Power. If you can get into it, you should be able to load firmware onto a MicroSD card and flash from there.

sorted!
Got it sorted, thanks very much..:good::laugh:
Hey guys. I want to start off by saying that I've researched answers to my following questions but the answers have raised more questions.
I will first explain my current setup and the process in which I took to get here.
When I first got my phone it was mj7
From fully stock (no root) I installed the OTA mje update.
I then rooted using Kongo
Installed SS
Installed the JellyBeans rom
Now wwhee I need clarification. ..
If I'm upgrading a new version in the future of this same rom it states to do a factory reset. To me this means use ss and perform a wipe on the rom slot the current rom is installed on. Is this correct? I ask because I've seen posts saying you should reroot before doing so. This leads me to my next question....
If I'm going to unroot and put back to stock as if I was going to do a warranty swap can I use the kingo unroot option and be all set? I've read that this works perfectly fine but then I see others saying you should flash the tar file. And that brings me to my last question. ..
If needing to fflash the tar file should I flash the current mj version my phone is on (I believe this is called the kernel version? ) or whatever is the latest one released ?
I totally understand these are basic questions that I should already know and have been talked about a million times but for a beginner like me and the HUGE amount of info out there I feel I'm getting some contradicting information. Please forgive my lack of knowledge, I'm just now stepping into this world. Thank you in advance... any and all input would be hugely appreciated.

One you have updated to MJE and achieved root and installed SS, you're good, until the next OTA rolls out from verizon. Currently I have my stock slot with root and nothing else. My first custom Rom slot has Beans' Rom on it. when people say to do a factory reset, they are talking about a factory reset on the specific rom slot you wish you flash. When you wipe a Rom slot, only that slot is affected, nothing else. So the phone will not lose root, or MJE, or SS.
So, in your case, back up your apps with TB or whatever you use, save your media on your MicroSD if you have one, and wipe the slot that youre going to flash. Dont wipe the stock slot, unless that's the one youre re-flashing. after you wipe, flash the new Beans 5, then either have google sync up your apps, or install titanium backup and go restore everything. Personally i had problems doing a full batch restore, so I only restored a few things, (i left out a bunch of system app data restores such as settings and dictionaries), but that should do the trick.
Hello,
I was playing around with my Note 3 LTE and I flashed (obviously) the wrong ZIP file which rendered my Phone function useless. I decided to re-flash the firmware to fix the problem.
I flashed the newest firmware for my phone, and it DID fix the problem. However, all my apps and settings are still here, the phone is still rooted, and my benchmark tests show that my phone is only 50% efficient compared to my pre-tinkering failed experiment.
I need help on how to do a CLEAN start, like when I first bought the phone. Is it doable via Odin? What do I need to do?
Factory reset in the phone settings ?
And do learn a few basics.

I did factory reset. It guided me through the phone settings again etc, but as soon as I booted the phone up it started automatically downloading my missing apps that were previously installed. AND my phone is STILL rooted. As I understood, flashing the firmware again should unroot the phone, and I should root it back again. I can't install busybox, for some reason, etc.
Thanks for your response. But don't be an elitist. I am learning, that's why I'm asking questions.

Grab your Stock Image, then flash it via Odin and it'll bring your device back to a complete stock factory state (back up anything beforehand - pics etc)

Thank you.
I just successfully downgraded from COD6 back to NK4 in order to alleviate concerns that downgrading back to Kit-Kat was going to be an issue. Reference post found: HERE. I am outlining the method I used to downgrade below, but this can also be a guide on how to upgrade to later firmwares.
I don't recommend trying to downgrade past NK4 and only downgrade if your dev says you need to! downgrading is risky and can brick your device! You've been warned!
Downgrade to NK4 or Upgrade to COD6
1.) Download Odin v3.09
2.) Download full Odin NK4 (Found HERE) or COD6 found, almost everywhere
3.) Unzip the file and there should be a file called "N910TUVU1ANK4_N910TTMB1ANK4_N910TUVU1ANK4_HOME.tar.md5" or your COD6 tar called, "N910TUVU1COD6_N910TTMB1COD6_N910TUVU1COD6_HOME.tar.md5"
4.) Open Odin v3.09 and click the button labeled "AP" and locate the tar file you unzipped
5.) Let it load, it will freeze for some time while checking the MD5 and then be ready to go
6.) Turn off your phone completely; after it is powered off hold vol down+ home + power until you see a warning message
7.) Hit Volume up to continue
8.) Plug in your device and and the it should light up blue under "ID:COM" and say something like "COM:1"
9.) Check to make sure your tar is loaded into the AP slot.
10.) Ensure that they only two boxes that are checked are: "Auto Reboot" and "F. Reset Time"
SHOULD LOOK LIKE THIS PHOTO: http://cdn.droidviews.com/wp-content/uploads/2013/05/galaxy-s4-odin-flash.jpg
11.) If you've verified that your Odin looks like the picture then click "Start" and be patient
*****************************************************************************************************************************
***If Downgrading You MUST wipe USER DATA following the steps below or your phone will boot loop on restart!***
***If Upgrading I Strongly Suggest wiping USER DATA to avoid potential issues from upgrading!***
*****************************************************************************************************************************
12.) Wipe User Data as outlined below by booting into recovery as soon as the download completes by holding power + volume up + home until it says, "Recovery booting" in blue in the upper left corner.
13.) After doing the factory reset and rebooting it will you can setup your phone like normal
These are the same steps if you want to upgrade with Odin, you just use the full tar of the upgraded firmware (COD6 in our case)
To Wipe User Data
1.) After you've clicked start and the file completely loads on your phone it will reboot and immediately enter recovery
2.) It will show and Android and a blue bar scrolling across setting up your system. It will reboot again after this
3.) As soon as the screen turns black hold vol up+ home + power to enter recovery again
4.) It will boot to the Android again and you should see THIS before the menu loads
5.) Scroll down to "factory reset/data wipe" with the Vol Down button and then hit the power button to select it
6.) Scroll down again and hit "Yes" so that it completes
7.) After it is done reboot and allow your phone to boot normally
8.) Setup your phone like normal
Done!
I vote for this to be a "Sticky".
Good job :good:
Thank you, I've been with 5.0.1 for the day and the battery was better on 4.4 and it looked better. I was going to try as soon as I got home but now I know.
I was googling how to downgrade and ran in to this. A lot of report saying it worked. I'm surprised this is possible with Odin. Thanks for the additional confirmation.
Just wanted to add. Downgrading to NK4 will require a factory reset, otherwise you go into a boot loop.

Makes no sense. It says must wipe user data....why on earth would you need to wipe / factory reset just to UPGRADE to COD6?
Guide needs proper writing...

Because doing an Odin upgrade or downgrade on your device does not wipe the data partition which is necessary when changing a letter versions of Android. For example, let's say you are going from Kit-Kat to Lollipop or perhaps Lollipop to Kit-Kat in a way similar to that presented in this "How to".
However, I get that new members need help sometimes so let me help you research your criticism.
Welcome to XDA.
Forgive my ignorance, but I am curious. When upgrading to a new letter version via OTA or a program like Kies, there is no factory reset done by default. The fact that a factory reset solved problems for many this go around aside, why is it a must when using Odin? I have upgraded ma few devices over the years to new letter versions without resetting so I am just trying to get a better understanding.

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.
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.
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)

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.
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 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?

Hey bud. and this by no means is trying discredit you, but the OP works just fine. Just did it. Odin 4.4.4 and wipe data after.
@hacker904 did you do this from 5.0.1 or 5.1.1 because I am on 5.1.1 and have tried to return to Kit Kat and it will not allow me to. Also waiting for testers on this one

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?
Hello, I'm new here.
I have a problem.
I forgot the PIN lock of my SM-G360F LTE (with Android 4.4.4), and I would like to keep all my files & documents inside it.
I don't have USB Debug enabled and I don't have a Samsung Account, so there's no easy way I can connect the phone to a computer.
What can I do to save my datas?
I've already tried flashing a Custom Recovery with Odin, but I haven't found a compatible one.
Please, give me an advice on what I should do.
Not sure if this will work for your version but it can't hurt to try. It worked for my stock unrooted SM-G360T1

Let me know if this works for you

It doesn't work (or I'm missing something) just because I can't unlock my screen lock to install the APK.
If I'm missing something, please tell me.
What I'm looking for is a way to enable USB Debug mode without unlocking the screen (something like a Custom Recovery mode).
Read the entire post including he comments cuz that link I posted is a step by step guide to unlocking the phone. If the phone has not been factory reset yet then do that first so it causes the phone to go to the Google email verification page then follow the in the link step by step and you will have the phone unlocked. What you are doing with this guide is making a custom path to the settings menu for the phone enabling you to do a factory reset from the backup/reset setting. By doing so you will remove the link to any and all accounts that have been uses on the phone this making the device start just as it would had you bought it from the store and was doing the initial setup. Let me know if you get stick anywhere or need help

But if I factory reset my phone, I will lose all my data, which I don't want to. Or via this "Backup/Reset" setting am I keeping my data?
Sorry for all this questions, but I'm pretty confused...
You will lose your data as this is the master factory reset but you can back up everything while in this menu to your Google account. After you factory reset go through the initial setup and come back to this menu and restore from your Google account
Can I backup my photos, music, documents etc. on my Google account? And how do I do it before resetting the phone?

Check out this guide here on lifehacker...
https://lifehacker.com/5976036/simp...droid-phone-from-the-desktop-no-root-required
Works great and doesn't require root to get it done. I know it is a lil different from what I mentioned earlier but I totally spaced this method until earlier today. Hope this helps you.
Man, my main problem is I can't enable USB debugging, having the screen locked! So I can't use any ADB method.
As far as I know there is no other way to backup your data without using adb methods without a custom recovery. Have you tried flashing twrp for your device and doing a full nandroid that way? I know that twrp has a compatible version for your device. Just search the forums here for you specific device model and flash using Odin 3.10
Here is the link to the twrp website go here to make sure you model is supported then download the tar.md5 file for tour device and flash using odin. Make sure to Uninstaller lies from your pc to avoid any issues with odin

I had already tried flashing twrp, but when I tried to boot in recovery I did get a Bootloop and the "Recovery is not seandroid enforced" error.

Are you using the hardware keys to boot to recovery (volume up+home+Power buttons)? If you try to boot to recovery from any other method it will cause a recovery loop. It's a known issue with all variants of this divice. It's gonna show the "Recovery is not seandroid enforcing" but it will go into recovery.
Of course, I'm using Home+VolUp+Power.
Im out of ideas outside of trying to flash twrp again through Odin

You can just try reflashing the stock firmware for your region in the AP slot of Odin from here.

It should keep all your data while it resets everything else like new.

Yes. In fact, if you've tripped factory reset protection (FRP), it is the only way to fix it. Here's an example of where this worked for someone else. Read my comment here:

Then also read the response that follows. Use the correct firmware for your device though at the link i gave above.

I understand that that guide has helped people and that's a good thing for sure. It's just that it's really the absolute most difficult way to fix a device that's under an FRP lock, as it's many steps rather than just the one step of flashing the stock firmware.

I appreciate the help and insight. Will definitely keep this in mind in case I ever run into this problem again.
