I want to learn how to flash/unlock - General Questions and Answers

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 would be willing to help, i have alot of disk space + pc resources.
I found an (a01q) (SM-A015M) guide here: https://forum.xda-developers.com/t/how-to-root-samsung-a01-a015f-ds.4147191/page-2#post-85246899. As it reflects in the SM-S111DL adb shell, as a01q. Can someone verify if this is a variant? Should we be flashing parts of the (a01q) (SM-A015M) firmware to the SM-S111DL?
Also have we tried flashing different CSC's to verify if the OEM Unlock option appears in devops? also check to see on each csc is you can just natively run fastboot oem unlock in the bootloader.
I had trouble doing a carrier switch, so we just went back to Straight Talk, and gave the device back. Waiting for a knockoff unlocked s22 ultra from alibaba so my frend can move to qlink. So he has it for now. I dont want to risk bricking it and him not have a phone.
However, I thoroughly went through that device and the ramparts, investigating information about the device. so im hare to help and once we get the replacement device for him then ill try again on that device.
1. try different firmwares to verify if the OEM unlock function appears. It'll most likely be early versions of the firmware.
2. Verify the device variants and see if parts of their builds are congruent with 111DL
3. test each flash and attempt to enable fastboot
This is a lower end device but with a debloat and bl unlock i think it would be worth at least a little time.
I have crap tons of tools that will save you time.
Can we set up a sharepoint?

Question Is my bootloader unlocked? Samsung Galaxy S7 (SM-G930VL)

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.

SM-J200BT Lockscreen Inquiry

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.

[RMX3085] How to unlock bootloader, root and enable call recording?

Hi,
I have vanilla version of Realme 8 phone running on Android 11. I turned it on to figure out the build number and it is A22, i did not connect or update it anyhow. Shall I do it before rooting? Now I want to root it and enable call recording. I have found the two conflicting guides https://forum.xda-developers.com/t/flashing-twrp-and-rooting-realme-8.4366399/ and https://forum.xda-developers.com/t/...otloader-flash-twrp-and-root-rmx3085.4386473/ and I don't know which is correct one to follow. Shall I install versions of Magick and SP flash referred by these posts or the newest up to date versions? By the second guide I also wonder why to install TWRP if the Magisk is not installed through it and it shall itself be installed via Flashify app so I would have another app to flash files into phone. By the second guide shall I follow the first part when I did not upgraded anything but my version is A22?
Btw. the guide https://forum.xda-developers.com/t/realme-8-rmx3085-twrp.4365305/ recommends to use fastboot to flash TWRP which is in contradiction with other two posts which claim that fastboot is not working. I also would welcome guide for Linux if there is that option.
Thank you!
I am planning to visit my mother. I can take bicycle, tram or walk naked through the woods. each is in contradiction, which is the correct way?
I will better ask my mother

How to really downgrade Galaxy S6 SM-G920F firmware from 7.0 to 5.0.2/5.1.1/6.0.1?

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
