is it possible to get into the engineering mode on my rooted xperia z2???
what's that!? don't you mean DEVELOPER OPTIONS? just tap a few times on settings>about phone>build number until it says you are a developer

Engineering Mode is another name for developer options for MTK devices.
THIS WILL NOT WORK ON A SONY DEVICE
1. Go to you phone dialer and type any of these codes;
Engineer mode
Huge list of developer options for testing touch,gps,wifi,display,etc.

I've been trying to find a way to disable fastboot, and I've scoured the internet and my device settings to try to find a way to disable the fastboot. My device is an iDeaUSA CT702 - MID A777 running Android ICS 4.0.3. It's a 7" Tablet, and not one of those big company devices, so answers are difficult to find. I can only tell you where the fastboot setting is NOT in:
1. "Settings - Power", because there is not Power settings.
2. "Settings - Applications"
3. "Settings - Developer Options" Since it's ICS, Developer Options are NOT under Applications.
I think there should be a way to disable fastboot using Terminal, or maybe ADB. Could anyone see if it's possible?
I used to use this method a lot to push files to my phone ( HTC Evo ). Then i switched to the darkside (iPhone) for 2 years. I have not used it in a VERY VERY long time. Can someone tell me how to enter abd on the note 2?
Bootloader/Download mode?
poweroff / hold volumedown-home-power at the same time
when screen loads press volume up
IDK
I was watching the video for bootloader unlock and he mentioned abd being different from download mode... IDK...
Bootloader mode is what I use to odin anything... IDK
either of you guys unlock?
Download mode is what you use for flashing. I'm not sure what ABD is, but I'm guessing you mean ADB, which stands for Android Debug Bridge, and you turn this on/off pretty much the same way you always have, though it moved from Settings > Applications > Development Settings to just Settings > Development. There should be a check box to enable it.
EDIT: Also, bootloader and download are not the same, though they do look similar. The Galaxy Nexus has both bootloader and download, the Note 2 only allows access to download as far as I'm aware. Bootloader mode is used for fastboot. Download is for Odin/Heimdall.

try to update and see if it there
important point. after confirming the desire to unlock and clear data, the bootloader really(!) unlocks only after the initial settings and when you see the gray immutable "OEM unlock" switch in the developer menu.
If you didn't see this item the first time, you need to enable the Internet and update the security policies, and at the same time disable them immediately.
This is the only reason for the appearance of the red inscription "only official ..." and this is the way to switching "rmm state" from prenormal to cheking.

Hey guys, my friend gave me his a21s to unlock it but I really can't find a way to do that.
The phone has a pattern lock that he doesn't remember it...
Also it doesn't have Developer mode enabled.
and in recovery mode, FactoryReset option is not available...

I think you are booting your phone into bootloader mode.
You do not have to boot your phone into bootloader mode, instead you have to boot in Odin mode. For that, switch off your SAMSUNG phone. Afterwards, press both volume buttons and insert the data cable into your phone simultaneously. (Note: your device should be of samsung otherwise the Odin application will not recognize your device. Your data cable should be connected to pc to enter Odin mode). Then a blue coloured screen will appear. You have click the volume up button once and you will enter Odin mode.
Thanks!

First you have to access developer mode. You have to tap several times on the build number. (Settings/about the phone) In developer mode you heve to enable oem unlocking and usb debugging. Wait for permission request on the phone for access of your PC when attached to the phone.
Next step is to unlock the bootloader.
After this you will be able to install TWRP, which finally gets you to the point where you can install a new ROM. Just follow step by step:
Install LineageOS on a5y17lte | LineageOS Wiki
wiki.lineageos.org
Of course, instead of Lineage, you can use any suitable ROM

Thank you for replying but as I said above i cannot unlock bootloader in any way i tried. So maybe can u find another solution? (Note: i tried following the link u send me and its not working)
How far did you get? OEM unlocking and usb debugging successful?
When putting your phone in fastboot mode and attaching it to the pc, check with "adb devices", if your phone is properly recognised. Using windows, it´s often the drivers. On my system, I had to manually select the ADB driver, since I got no connection before.

thanks for replying again
i tried to oem unlocking and usb debugging but unsucessful
furthermore my pc cant even recognise my phone when i turn on usb debugging or change the usb to media transfer protocol (mtp) mode after i flash stock firmware (it worked before i flash the firmware)
how am i gonna install anything if my pc cant even recognise my phone????
(ps: your question "how far did you get" my answer is i cant flash any mods or unlock anything. bootloader locked.)
Can you see the "developer options" in settings/system when scrolling down ? If not, then:
How to access developer options in Android
Step 1: Go to Settings > About Phone.
Step 2: Tap Software Info > Build Number.
Step 3: Tap Build Number seven times. ...
Step 4: Once developer options are activated, you will see a message that reads, You are now a developer.
Within developer options there are options to enable usb debugging and oem unlock. I recently did this on a Galaxy tab and saw..nothing.
First I had to establish a network connection to my wifi base. Weird, but this brought those wanted menu items...
For further connection, check your computer drivers. Both the manufacturers usb drivers and adb driver are necessary. While connected to a PC, check, if you´re on Windows, the device manager, if the proper driver is chosen.

I see the developer options and the usb debugging switch
But there are 2 problems
1. My pc running windows 10 cannot detect my device (like showing it as a disk so i can copy files to )
2. In developer setting there is no OEM unlock option, which is weird. I triee many solutions but cannot get acess to OEM unlock. I even tried to unlock it with ADB ut its useless since my phone cant even access fastboot mode.(download mode is considered to be fastboot but ADB wont recognise my phone)

heimdall finally recognise my phone but whenever i try to flash twrp.img it says
"Only official binaries are allowed to be flashed(RECOVERY)" (the phone itself) HELP!!!!
*good karma +1*
On any other device, you would have enjoyed your new TWRP since several days. But Samsung is eager to build as many hurdles as possible, to prevent changing the original software. They invented "KnoxGuard" to "protect" the phone. In your case, it´s aprotection against it´s owner
The error message means, that your phone isn´t successfully unlocked.
Try this:
"FIXED IT!!
The time trick actually worked.
All I had to do was turn back the time by like a year, reboot, enter recovery mode, delete cache, re-enable OEM unlock, spam the update phone button, and boot into download mode!"
