bricked On5 after changing "OEM" setting in Dev Options - VERY Frustrated - General Questions and Answers

i am not a phone geek. i'm frustrated at the difficulty in getting a clear answer as to how to unbrick my G550T after getting "Custom binary blocked by FRP lock."
I've attempted approx 5 different "SOLVED" methods, none to any avail.
I know i'm not permanently bricked - i've been through this before. someone, please help???
I've downloaded Odin but it won't see my phone even when i boot my phone into DL mode.
Please help, someone?

Have you installed the samsung USB drivers? Tried different USB ports and/or cables.
You're on the right track here. Flashing stock firmware should solve it.

Try uninstalling any of these if you have them:
1) Kies
2) Smart Switch
3) Samsung USB drivers
Then reinstall just the drivers and try Odin again.
Make sure it's a stock USB cord
Try different USB ports (i.e. 2.0, 3.0)
Try a different PC

Interestingly, I was unable to install Kies3 - kept stalling. I'm on a Samsung laptop/Win7.
Would Kies not help if i am able to install it?
I'll attempt your other suggestions. thanks

Kies can interfere with Odin, all you need is your stock firmware file, the USB drivers and Odin.

I smashed my galaxy note 5 out of anger today and really need help!
I rooted my phone with a custom kernel about a month ago and it constantly rebooted during calls etc.... I wanted to use Arter97's kernel with CWM but it will not boot into recovery.
My phone will not connect to the pc but will only charge! I have tried every option and no luck! I tried my other galaxy s6 and the drivers worked but not my note 5!
The root used to work before but I did a factory reset and not it says root is not properly installed!
My issue is phone will not connect to pc to use ODIN and CWM will not boot into recovery to install Arters Kernel for my Galaxy Note 5 SM-N920W8
Please help me before I cause some serious damage to anyone gets in my way in real life!

The device still works, just the glass back of the phone broke. The phone is not being recognized by the computer at all even before I smashed it.. I tried every method but it works on my s6 right away but not the note 5. It says my phone has no root now after I factory reset but my kernel is still the rooted version... 3.10.61 noble kernel v0.1
Did the root damage the hardware that it would connect to my pc?

Try a different cable and a different USB port when in download mode.
I had the same once, it's not the end of the world.
I've found the more generic the cord the more likely it will work especially if your port is bent

Tried multiple ports and multiple cords... Nothing.. at all phone is in a bootloop that wont clear either
I went to a few stores they said They have to change the motherboard for my note 5 SM n920w8... apparently that is why it changes with the usb on the pc but not data sync.... Im kinda lost on this because why would it do that!
Please help they are trying to charge me 240$...
To anyone who can help me fix this issue I will be more than happy to pay 130$

It seems like I have multiple issues now, The phone is in a bootloop and will not pass Samsung Note 5 Logo, and the other problem is the device is not being detected on my computer.. Now it kinda seems worse because I am not even getting the error anymore it just won't connect.
I can still enter Odin download mode and Recovery mode yes.
I took it to the shop and they said they can fix itbut will cost around $240.00 to replace the motherboard so it can connect to the computer. If I can make it connect I can fix this whole issue..
I have tried multiple cords, multiple computers, disabled and enabled drivers, uninstalled and reinstalled drivers, updated drivers, every possible way you can think off with the computer.

Galaxy s6 stuck at boot? Unable to fix

Hi xda members, im new in here and i was hoping for a bit of help
My phone is galaxy s6 SM-920T
I was reading on the net when the phone powered off and started restarting and restating again and stuck at book logo "powered by samsung".
I am not able to go into recovery mode but i can open the os download mode.
Tried many times with odin and no luck
I think due to the phone being full encrypted by me nothing can be done, is there any posibility? Thanks
The same here. I cant get into recovery. I had Terminator Rom installed. I can get into download mode but odin doesnt detect it. I eventoght the usb door was damadged so paid 60$ do replace it at samsung. But odin still doesnt not recognize it. Odin does recognize my Samsung Tablet 4.

Have you made sure you have the latest Samsung drivers installed on your computer?( http://developer.samsung.com/technical-doc/view.do?v=T000000117) And after that, try to see if Odin recognize it download mode, after you have confirmed you wanna flash new Rom ( volum up)

I've had cases where you had to put the phone into download mode THEN open Odin for it to be seen. Maybe try that.
With it in download mode and plugged up open devices and printers and scroll to bottom and see if it shows up. Would be called gadget_serial. Some computers take a while to load the drivers for it as well. You may want to click little popup menu on bottom right of desktop by the time and date and see if it shows it is loading drivers for it. It will not show up until the gadget serial drivers are installed.
Thanks for the help. Nothing worked. It doesnt not recognizes the S6 only my Galaxy Tab 4. Could it be that the usb door wasnt repaired proprely ? Windows doesnt even detect the phone no gadget_serial. Nothing.
Make sure that You're using USB 2.0 not 3.0. My Note 4 worked through usb3.0 without any problem. And S6 doesn't. And if Odin reflash won't fix it. Get pit file and flash it with it.

First thing to try would be flashing stock firmware with Odin.
https://www.dropbox.com/s/rb8iduv2o9i1ece/G920TUVS3DOJC_G920TTMB3DOJC_TMB.zip?dl=0
I recommend Odin 3.10.6
https://www.dropbox.com/s/1dlmxtc0ic7u7ew/Odin3_v3.10.6.zip?dl=0

already done, with same results stuck at boot loop, tried to add a custom recovery which got denied by knox

Sounds like DRK may be damaged.
Take the stock OKC firmware and open the archive with 7-zip or winrar and extract the system.img and boot.img.
Download and unzip this:
https://www.dropbox.com/s/bsreazoonsw4gwv/tar-Tool_Odin3-v3.07_by_mkh.mourad.zip?dl=0
Copy/paste the system.img and boot.img into the software directory and run the batch file. It will spit out a system.tar.md5 and boot.tar.md5
Flash the system.tar.md5 with Odin as AP then flash the boot.tar.md5 as AP.
Report back
thank you gonna have to try tomorrow due to bad USB cables, will let you know thank you so much for your help
If all else fails, just boot your phone into download phone and install Samsung Kies and restore it using that.
You will need the model & serial number of your phone. It will restore the latest stock firmware on your phone for you..

You cant, I suggest using a friend or family member's serial number that has the same model phone.. the serial number is a way of identifying the correct carrier specific rom.

Have you tried uninstalling all the USB drivers for your device, restarting PC, re-installing drivers then restart PC and then try connecting your device.
When you updated, did you boot to stock recovery and factory reset and wipe cache partition then reboot? Sometimes failing to wipe during update can cause things to not work correctly.

Yes I tried everything uninstalling and reinstalling all the drivers and dozens of restarts nothing helps.
Nope when it got updated I didnt factory reset or wipe cache partition cuz i didnt want to loose my data.
It was an official update.
Now I just did the factory reset and cache partition wipe nothing helps
My pc still wont recognise my note 4.

And when you right click on the driver with the yellow triangle and select update driver, it does nothing?
Have you tried manually updating the driver and choosing the option to select from files on your PC instead of the auto-update feature? You can use this method to navigate to the folder that the Samsung drivers are installed in and select them from there, this should load the drivers.

You changed the USB settings as suggested and nothing changes?
You disabled anti-virus before installing the drivers?
You disabled fast startup? (If your PC has this feature)
How USB works on your note 4 versus how it works on your other devices may have slight differences, that would explain why your others connect and the note 4 doesn't.
Have you enabled USB debugging developer options?
99% of the time this is a PC hardware/driver issue, not an issue with the android device in question.

Samsung Galaxy Tab 2 10.1 Help!!

Hi everyone, I am a new person in the forums, so please understand if I'm not good at some stuff and if I'm posting this in the wrong place
Well, story is that I found my old Galaxy Tab 2 in my basement after 3 years, and I got it to turn on (no factory cable, 1€ chinese cable). Android version is 4.0.3.
Found a couple of roms in the forums for 6.0, and yes, I've done it before on my phones.
Computer cannot recognize the tab, only says "Unrecognized device", even though I've tried every driver there is to it. Tried kies, no help. Tried odin, no help.
Neither of those detect the tab either, so I rooted it from the tab itself with KingRoot.
Now the tab is rooted, and I tried to flash TWRP to install 6.0.
It says that the recovery is flashed, but when I try to reboot to recovery, it only restarts, with nothing.
It goes into download mode just perfectly, but when connected to the pc, it still doesn't detect it.
I do not have money to buy a new tablet, so I would really like some advice.
Thanks!
hello
go in download mod ( power & vol+ )
go back to origin
use cfautoroot (all needed in it odin + drivers + cfautoroot)
use a new cable
after that install twrp, os ( first cm12.1 )
regards
Hi, will try!
Don't set auto reboot in Odin.
Once TWRP is flashed wait 1 minute and unplug the tab.
Now directly boot into TWRP, else stock recovery get restored on boot.
You should update over OTA to 4.1 or 4.2 if available first, else you'll have to flash a newer bootloader using Odin to avoid graphics glitches at boot.

I was flashing something onto my device and now I only get the "A error has occurred while updating the device software" screen and I've tried using Odin to flash the original firmware on os but Odin gives me this error: "Can't open the serial(COM) port" I tried every fix and none of them worked. Can anyone help me to fix this?
