So, I am currently having this Samsung Galaxy J2 TV (SM-J200BT, Android 5.1x) that I have been locked out for a couple of months now and I still have some important data there to be fetched out from the device, therefore leaving the factory reset option as the last resort. I have tried using Dr Fone and iMyFone but my device is not listed on their supported devices at the moment. I also have tried using ADB but unfortunately, USB debugging is disabled on the phone. At one point, I even have considered to apply the method which involves copy-pasting a long list of numbers and pasting it into the password field then crashing the lockscreen, but unfortunately again, the phone does not even allow me to copy nor paste anything while it is locked. I also have considered using the GSD tool to install the phone's boot.img file for this matter but the file that I have downloaded for my device seems to be unsupported or corrupt according to the software and carrying the next step into Odin just doesn't do anything either (TWRP included, since the 'galaxy j2lte' file was the closest one I could find).
The only possible solutions that I could think of, at least to some extent, that is still giving hope at the moment is to somehow find a roundabout method in activating USB debugging while the phone is locked or have a proper firmware/file that can help me succeed in installing into the phone and unlocking it using Odin or some other method, while at the same time, NOT LOSING ANY DATA. Any help or suggestion is widely appreciated, thanks in advance.

I want to add flashing and unlocking services to my families business because it's in demand. I didn't see any general guide pop up on the search list. Can anyone help?
There's no "one guide fits all". Each device manufacturer has a slightly different way of dong it. You have to visit each device forum and find the HOW-TOs on how to unlock and flash each device.
it's not difficult, but you have to ensure you do it properly or you risk potential damage.
the most comman way to unlock and flashing is-
first make sure you have enough drivers for devices (can also use ADB driver installer to find drivers)
and you also must have stock rom of that device (in tar.md5 format)
start with downloading drivers and stock roms of many devices you can.
after download them put them in your pc and creat a list of devices which drivers and roms you have
also download latest version of odin and some videos about "how to flash rom with odin" these vedios will help you in future.
test yourself by flashing your own device first
if everything done correctly then you can try it on customers device (which is in your list)
dont do anything else with devices only connect them>install them with right drivers> open odin select tar.md5 files and flash
if unsuccessful return them their device and ask them to contact mobile care...
[do everything on your own risk]
Posting what device you want to flash/unlock would be a start
Using the search button is the answer

For flashing custom roms, to begin with you should figure out how to do the following by searching on XDA:
1 - Install ADB drivers
2 - Root a phone
3 - Unlock the bootloader
4 - Install Custom Recovery
5 - Make Nandroid Backup
6 - Flash Custom Kernel
7 - Flash Custom Rom
The methods and files are different for each phone but broadly speaking they are the same. So perhaps you should try it out with your own phone first, then try more and more and you will get a good hang of it. Its not really that hard, just make sure you read and follow instructions properly otherwise you can brick the phone.
For unlocking phones, I am not sure. If you google there are some methods for popular phones like on this site - http://www.wikihow.com/Unlock-Mobile-Phones but I do not know if that works. You can always use a website to get the unlock code and charge your customer a little bit more than what you pay for the unlock code.
I've searched in vain on how to manually update to latest security patch, now that Sammy informs me that my device has been modified in an unauthorized way and will not allow OTA updates.
In sammobile I can see that my phone has a new security update. My question is if I have to install the complete firmware or security updates are available from some other source?
With respect to the latter, Sammy doesn't seem to make security updates available on its page and I would have preferred just patching a smaller file and not the whole firmware.
Any guidance appreciated.
Cheers!
if u use the home csc file when flashing new firmware with odin ur device will not been wiped, just updated without losing data.

Many thanks Roberto, for your answer. Unfortunately, I have a few more questions which I hope you can help me with. At the SamMobile it says Download Odin v3.13.3 and running it displays the following warning: see image here.
It says I have to: ...delete my Google account (Sammy account) before downloading the binary. I suppose that by "downloading" they mean moving firmware to the phone, but it doesn't seem very logic...?
The unlocking referred to I suppose is the OEM unlock, and no problem there.
I haven't found any explanation why this new measure of having to delete the Google account is necessary and wonder if you could help clarify it?
Cheers!

1. If flashing stock firmware you don't need OEM unlocked.
2. OEM unlocked is used for flashing non signed Samsung files/firmware. IE: twrp,root etc.
3. Using the home_csc ( not CSC ) as stated in the previous post should keep your data. It is recommended to flash the 4 files when upgrading. But always do a backup first.
4. If you have twrp or root you will need to redo again.
5. Usually deleting any accounts from your phone turns off FRP protection.

Thanks spawnlives for your response.
As mentioned in the subject I had TWRP and Magisk, and, first time around I was aware of loosing apps, their configuration and internal data. I would think the same would happen any subsequent times - hence my question how to install only the security patches.
I suppose it's not possible... In that case, with security patches for my S7
sometimes every month, it's not worth going through the hazzle of adding TWRP and Magisk.
Shame on Sammy penalizing rooted customers when it won't update the Android version of more than 2-year old phones.
Another, shame on Sammy has to do with how security patches are more frequent for "important" countries (i.e. where Samsung sells most). In the previous link above, just select another country, say Costa Rica, which only has received one security update for this year - as opposed to three for Germany. Why?
Greetings, everyone! Usually I have good knowledge regarding rooting, custom recovery and flashing a new system. But this time I tried to downgrade the Samsung Xcover 3 of my friend and flashed the Android 4.4.4 sboot.bin with Heimdall - unfortunately I forgot to tick the "no reboot" option. The moment it rebootet, I know do not have any access to the phone anymore.
When trying to bring it into download mode, it vibrates, but nothing else. Neither Linux nor Windows recognizes the phone. Is it dead? How to gain access so that I can flash the correct sboot.bin? Any tricks you recommend?

If you can find a "debrick.img" or "debrick.bin" for your specific model number, there is a method that uses your external sdcard to boot the phone then repair it while it is booted.
But, first, you need to find a debrick.img or debrick.bin for your specific model number. If you can't find a copy for your model number, you can try finding another member here that has a rooted Xcover 3 with the exact same firmware as your device had and have them pull a copy of debrick.img or debrick.bin from their device then upload it for you to download.
If you can't find that, the only other options are to send the device to a repair shop for JTAG service or replace the motherboard.

I did not even expect that someone would answer here. THANK YOU SO MUCH, @Droidriven! That gives me hope to rescue the phone instead of having o buy a new one for my friend. Here is what I actually did wrong: In my attempt to "downgrade" from 5.1.1 Lollipop to Android 4.4.4 Kitkat (downgrade needed to be able to root the phone) I flashed the sboot.bin of Android 4.4.4 Kitkat with Heimdall and forgot to tick the NO REBOOT option.
That being said, the phone now only vibrates when using my JTAG (yes, I actually have one and the phone vibrates, but does not boot into download mode and is not recognized by neither Windows nor Linux). So, how to build this unbrick image? Could you help me with that? Both firmwares are to be found here:

Another thread with sadly no file uploaded was to be found here:

As for the creation of the unbrick image, do you recommend this tool? I currently have no Windows at hand but can provide you with the original PIT file if you can run this tool to create it:

Thanks a lot for your help. May god return your efforts in helping me!

Sorry, I'm just now seeing this. Did you ever make any progress? Yes, I think there are some reliable methods to create debrick.img/debrick.bin files, there is one such method posted here at XDA in a random post in a thread here but I can't remember exactly what thread it is.
Hi all,
So I've inherited an old S7 and I'm trying to install LineageOS on it. I've got the build for the OS done already, but to sideload it, I need the custom recovery TWRP installed on my phone, but I haven't been successful getting it installed on my phone, and after talking with the folks on the LineageOS subreddit, it's unclear if my phone's bootloader is unlocked, which it needs to be to install TWRP. I've enabled developer options on my phone, enabled USB Debugging, and I've enabled OEM unlock. However, when I follow their instructions to install TWRP, I boot into recovery mode, and the stock recovery mode loads.
I can't tell if my bootloader is unlocked or not, and any test I've followed apparently doesn't work on my phone because Samsung. I found this tutorial on this forum about unlocking my particular phone model - https://forum.xda-developers.com/t/unlock-bootloader-sm-g930vl-straighttalk.3436986/ - but I have 2 problems.
1) The first response links to a guide, but almost all the download links the author listed no longer work - https://forum.xda-developers.com/t/...ning-to-stock-a-galaxy-s7-or-s7-edge.3411039/ - I believe I already have the Samsung drivers and ADB setup on my computer; I was able to find a download for Odin; but I have no idea where to get the root images, and nobody else in the comments posted an alternate link that I could see.
2) In the original thread, other users suggested just using the Eng boot instead of the guide I listed, but nobody listed a download link, and I don't know what it is, or how I would tell an official download link from a questionable reupload.
If anybody can help clarify some of my confusion, or point me to where I could get the downloads I'm looking for, I would very much appreciate it.
Hello
I've been reading forums and downloading files for days. Many of the links in the posts no longer work. Posts are 5 years and older. There are no new ones. At least not one that actually works. Downgrade I mean. That's why I wrote this question and I'm asking for help - how to really downgrade my Galaxy S6 G920F.
Thanks for the help.
PSA: Downgrading WILL void your warranty!
What have you already done (what method, software) have you already tried?
The 100% surefire way to downgrade your phone (or any android phone really), is to:
1. Backup your phone data.
2. Switch the phone into download mode, connect to PC, boot into TWRP recovery through fastboot
3. Wipe your 7.0 firmware and all data
4. Flash android 5.02 ROM
For a samsung phones ODIN + Freya is also an option. Odin is a samsung's firmware flashing tool, Freya is a 3rd party program that can download the stock firmware android for you. All of these tools are available online, and you can ask on a samsung subsection of XDA about how to use them - people can give you up to date links.
I'm laughing because you write quite a lot in three days. Of course, this method does not work.
Is there anyone willing to help?

That is assuming they have TWRP.
Also, the part you mention about "boot into download mode, connect to PC then boot to TWRP via fastboot" is not correct because Samsung is not compatible with fastboot, adb works but fastboot does not. Some Samsung devices technically have a "fastboot mode" but it isn't functional, it doesn't respond to fastboot commands, it's basically useless.
Also, you can't flash a firmware that has a lower binary than the currently installed firmware so if the binary of the downgraded firmware is lower than the binary of the currently installed firmware, the downgraded firmware can't be flashed.
Samsung is making it harder and harder to downgrade their devices.
OK. I'm afraid I'm missing the point of what's being said.
I know it is possible and there are also posts about it, but they are old, the links in them do not work. I'm asking for an expert who knows how to do this, philosophizing about what it would be like if it somehow doesn't really help me and I'm not interested either
I'm only interested in a positive thought, help and not brainstorming, if you understand me?
No offense
