I received the OTA update a couple weeks ago and it installed "N920VVRU3CQB9" (Nougat update). I'm having few issues with the phone where I'm stuck at the login screen with no keyboard (full details here).
My question is - if I flash the same ROM using ODIN, does it wipe all user data (pictures, videos etc)? After flashing the same ROM, does it get stuck in boot loop as it requires going into the recovery mode and selecting "wipe data/factory reset" which deletes everything.
Thank you.

If you flash that it usually does but there's no point in doing that because a factory reset does the same exact thing.. If you're going to flash anything at all or do anything at all to the phone then ENABLE oem unlock in developer options!!
Thank you MrMike2182. If flashing the same ROM as OTA will cause a factory reset. I would lose all my data, right? Is there any way to keep the data?

It depends on what you're trying to do.. When you do an upgrade it preserves your stuff. When you do a downgrade it tends to need a factory reset in order to work.. What I would do in your case is use Smart Switch from Samsung and backup the entire phone and even send any important documents to your computer and do a factory reset anyway that way it's a fresh system install and doesn't have any junk left over from all the other updates and whatnot and then after the factory reset is done just hook the phone back up to Smart Switch on your Windows PC and click restore.. It can pretty much put everything back including apps, music, contacts, documents, home screen theme etc etc. Works pretty good if you ask me.
Do NOT forget to enable OEM unlock!! Seriously.

So I'm S-off, Firewater, SuperSU, CWM, stock software, I have not loaded a ROM, fastboot flashed the nohbootimg firmware update, added the HTC browser, and flashed the OTA-killer.
Can I do a Factory reset without it messing something up? I'm having 3 issues that I want to see if a reset will fix, one is my alarm clock keeps turning itself off, another issue is that when I turn the phone on it seems to take a long time to "Prepare Sim card" , and the last issue is that I get a email "login failed" notice which is poping up before the phone starts seeing the data connection.
Thanks

If you are simply stock and rooted... you can factory reset using CWM without any issue.
Worst case scenario if you are backed up...

Since you have not installed a ROM I would think a factory reset would be a good first step. You will probably lose some if the customization you have done, but I wouldn't think you would lose root or anything like that. I believe a reset will just wipe the data partition ( maybe dakvik and cache as well).

Thanks! Just curious, I'm trying to learn as fast as I can , how does CWM reset differ from the the stock one?
And do you think that the CWM reset could help with the issues?

They both typically wipe the same partitions however the stock recover also resets some radio elements which is why you will always see me suggest to someone with radio issues to do a factory reset from stock recovery.

I used the reset in CWM and I'm going through the setup now, I guess we'll see if this helps. Thanks guys!!!
Well the alarm is staying on so far and I'm not getting the email login failure but I think I lost my CWM, guess I'd better reload it.
Interesting, I can't seem to get into my hboot mode? hmmmm
nevermind, I'm a dolt, forgot to turn off fast boot and I Still have CWM but when I select reboot I get a message "Root access possibly lost. Fix?" Anyone know what this could mean? Should I Pick "Yes - Fix Root" . I'd assume so, what the heck lets see what happens. lol
I got a new iPhone 7 and wanna sell my old Android galaxy 5, so, my concern is whether the simple deleted data can be easily recovered by some data recovery tools, because there are many sensitive data on my old galaxy 5. So, i wanna know if it's necessary to completely erase data on Andorid before selling? and how?
PS: does factory reset can completely erase the data without recovery?
factory reset should be totally enough.

the data can be accessed by data recovery software with only a single factory reset. There is a CNET post about this. A more secure way is writing random data to the phone to overwrite the current device. You can see more details from this guide: how to safely erase android phone
A few steps.
1. Factory Reset.
2. After Factory Reset, go through with setup to be able to accept Files from your PC.
3. Copy and Paste Junk Files, Pictures, Audio, or whatever isn't important if accessed at all, but Move onto Phone MORE DATA than what was there before which Overwrites All of Your Previous stuff.
4. Do Another Factory Reset.
Now, your Phone is Safe to Sell.

so, if the factory reset can't wipe Android completely, do you have a great way to erase data from Android phone without recovery possibility?
Hey,
I want to completely wipe my Samsung S6 before I sell it/giver it away, so that when the new user won't find anything when they scan the device for deleted files.
What's the best way to achieve this?
I figured Encrypting my device and doing a factory reset or wipe within TWRP would suffice, but does it? Has anybody achieved a completely clean device and how?

IShredder works for me.. Or just do it oldschool.. Delete and factory reset. Stuff your phone with crap files to overwrite old files and do that as many times as you feel safe and done.. And if you want to experiment with it try to use some recovery software after to see if you got rid of everything

I think that only works for traditional hard drives rather than on flash memory (SSD/NAND) -- It would seem to me encrypting and factory reset/full wipe in TWRP would work better.
Installing stock firmware encrypts the phone, factory reset/full wipe to completely wipe the data including the key that unlocks the data and doing that another time would probably make data inaccessible especially after a time of use.
AFAIK custom roms are usually not encrypted to allow root to be installed.
I could be wrong however... Has anybody got experience using this method?
The phone needs to be encrypted first before performing a factory reset. Factory reset will make it look like all data has been deleted but actually personal info like photos, texts, emails etc will still be stored in memory and just marked as deleted. This means they can be quite easily restored if someone decides to use a data recovery tool on your phone once it's out of your hands. Both data encryption and factory reset can be done easily from the phone's settings. Data encryption is in the Lock Screen and Security section. Reset can also be done remotely from the findmymobile.samsung website
Hi. i have an issue with my tablet and samsung support wants me to do a factory reset.
My question is then if i flash a firmware from samfrew.com will that remove as much data as a factory reset? or is the data stored in another partition or something similar to that?
A Factory Reset - as it name implies - only restores Android phone to the state it was brought into the market, it does NOT alter phone's Android as flashing a firmware does.
ok? so are you saying that doing the factory reset will rollback all the software updates samsung has rolled out?

No, but factory reset, will wipe your internal drive completely. If you have a sd card store all your photos/music etc on sd card.
Only real time, you want to flash stock firmware
etc, is if you eg... want to upgrade your firmware to newer versions, or come back from root.etc.. etc.
Chances are... if you don't know what you doing... you can soft brick your device etc.!
Factory reset, seems like the better options.?
Even though once or twice (in the past) , a factory reset, did not help, where flashing correct, Official firmware version, actually help solved my issue.
So it's your choice.!
Good luck.

What's the issue?
Try clearing the system cache; it never hurts, it's easy and can cure erratic behavior.
Old loads will probably benefit with a clean load but for minor issues it's a shotgun overkill approach to troubleshooting.
Techs like because it works and makes things real easy... for them, not you!
Worse the issue can easily reoccur if it was caused by an app, setting, etc. Normally it's best to find the root cause rather than do a factory reset.
Exceptions are old loads and if you did a OS upgrade, in which case a factory reload fully warranted.
A reflash should only be done to upgrade or if the original factory load image has been corrupted (very unlikely).
ok.
i have an samsung galaxy tab S6 and since the upgrade to Android 11/OneUI3.1 international key on any hardware keyboard stopped working. regardless of layout set. Dvorak etc. does work though.
so i think it is a software bug and not some lingering configuration.
support asked me first to clear the cache on samsung keyboard app and when that didnt work they asked me to reset all settings in general management. no bueno there either. next thing they want me to do is facory data reset.
so my thinking is if this is a software bug that won't do any good. but reflashing the tablet with android 10 should work if the faulty software is in android 11, or rather in samsungs OneUI i guess.
does this make sense?
but i digressed. what i wanted to learn was what data is affected in a factory reset compared to a firmware flashing.

I basically answered your questionin above post..!
Factory reset will wipe your internal data.!
Where as flashing correct Official Firmware depends...... .!
eg If you do a dirty flash... you keep your data..! Data stays intact, but chances are "anything" (system apps) can get corrupted.?
Resulting eg, in excessive battery drain or an app not working properly.
(In Samsung devices when flashing you use /if you flash... eg Home_CSC etc with the other relevant files)
Otherwise/alternative, if you flash
(.. with the correct Official Firmware using)
eg CSC_XXX file, your device will automatically factory reset..!
Bottom line is, it depends how you flash your device.
example.....
HOME_CSC_xxx -> data will stay intact.
CSC_xxx-> device will factory reset.
Note,
If you knew the basics, about flashing official firmware......
you should have known, above information.?
So i suggest that either you do some reading /research, regarding flashing correct official
Firmware etc or you stand risk of soft
bricking you device..
Good luck

All critical data photos, contacts, music, vids, etc should already fully backed up, redundantly.
The whole idea of a reload or flash is a fresh start from issues that are present.
OS's are 100% expendable, critical data is not.
It's a little game to see how long you can keep a OS copy running well, but that's all it is.
Erratic behavior could indicate a virus or rootkit.
A benign instability could end up corrupting important data, even backups.
I'm ready to reload -now- should be how you roll; keep your data organized and backed up.
If you have a SD card slot, use it as a data drive. OS/programs/download folder on the internal memory or primary drive, and all critical data on the the data drive. You can nuke the OS but your data is safely (hopefully) still on the data drive, you backup that drive at least twice.
Hi,
I'm in the process of trying to flash my phone back to stock because I messed some stuff up in the hidden menu. I've never really messed with any of this stuff before, but it seems like Sony offers all the tools I need and it seems straight forward. I have a couple of questions, though. Will flashing the binary found at this link reset the phone to completely out of the box condition and will it function as if I never messed with anything? Will it function as if it's 100% stock and still receive updates normally?
I've wasted my entire afternoon trying to figure out how to factory reset this menu and I'd like for the phone to just back to how it was out of the box.
Thanks in advance for any help you guys can offer.
The phone is a Sony Xperia 5 IV, btw.
A Factory Reset only removes all apps added by user and user-data.
Hence reflash Stock ROM.

Thanks for the reply. I assumed that the rom reflash would reset everything, but I've seen posts on here saying that a rom reflash didn't reset that menu and I'm not sure which is accurate. So, would reflashing the rom actually reset those settings?
