yes sorry i looked at all of them and they all involved well just flashing the stock rom but i cant get my computer to see my gs4 on download mode...i got the drivers and odin installed.
Well, this thread has a couple of ideas...

You might also want to look at the TWRP thread in the development section.
Try again to get into recovery, the key sequence can be tricky, make sure you are doing it just right. "Doing it just right" has been discussed many times.
Also, look at this thread, maybe it will help...

Yea, I realize that thread is about MF3, but it still has ideas that might help you.
There are also a ton of threads about how to get your PC to recognize ODIN.....search.......good luck.
yeah ive been at it for hours man those links can all access the recovery i cant... i tried everything got the drivers up tried all the odins and its just stuck on "downloading do not turn off target" and my pc doesnt see it...
Odin finally recognized it on the pc in download mode and i was able to flash the stock rom but it seems it wasnts successful...it still just vibrates and vibrates when i press the power...

Take battery out, back in, power+volumedown, download mode, Install Samsung Kies, do Kies update, connect to PC, Tools-> firmware initialization, take battery out and type model/serial Number, wait patiently until it finishes.
Try different USB port or different PC. Use stock USB cable comes with original box.
If Kies screen get stuck at model number section, you did flash MF3 triangle thingy -> unsolveable brick. Have to go thorugh warranty replacement.

Hello
I have F version, country Italy
I tried install a few roms but I always had freeze screen and reboots. So finally tried restore from Odin and I had brick. I used the last firmware from Odin and one from this forum of "Fast download" And this only shows the bootimage and reboot again of freeze
In download mode shows in System: "custom", Recovery: Samsung Oficial
I cant enter on recovery mode
Im not sure if Samsung I still give me "warranty"
Anybody can help me ?
PD: sorry4myenglish
best bet is to try and flash another ROM if you can get into download mode still (making sure that you flash a ROM for the right version of your phone).
Samsung probably wont honor warranty as you tripped KNOX when flashing in the first place (that voids your warranty and I belive download mode states this)
EDIT:
the right version for you is the first link on the thread: http://forum.xda-developers.com/s6-...icial-stock-roms-firmware-aoj5-g928f-t3231589
as long as you have the SMG928F version from Italy

well it might be a corrupt download, but theres no MD5 for the files form that thread to match.
Can you enter download mode? If so then I would probably flash a custom recovery and install custom ROM just to get the phone running again.

I just tried enter but only shows the message "recovery mode is senandroid enforcing" then shows (after 1 min maybe) the screen like a tv without signal
Some days ago I had exactly the same problem as you. You need to download "Smart Switch" on PC (something like samsung kies) and then recovery your phone through it. This samsung app will download a new system and completly repair your phone, after that if you want to install audax rom or something else you MUST go to developer options and enable USB DEBUGGING and OEM UNLOCK or you will have the same problem after rebooting phone.
Hope it helps, I bricked my phone for 1 day and managed to repair it with it. ODIN and all other stuff didn't worked.

That message means that SElinux is enforced and the way around that is a custom kernel as the stock on is forcing it always.
Natherul after I bricked my phone by installing audax and the unchecking in dev options "oem unlock" Smart Switch was the only one thing that actually unbricked my phone :good:

EDIT: Problem solved!!!
I used this tutorial: https://forum.xda-developers.com/sa...very-samsung-sm-a510f-fd-exynos7580-t3314399/ to install TWRP and root my SM-A510FD on 6.0.1 . My device was rooted and working perfectly until stupid me decided to turn off "OEM Unlock" and i restarted my phone and now it says "custom binary blocked by frp lock" The only thing i can do is go to the Download mode. I tried to use Samsung Kies and Smart Switch when in Download mode but they tell me that my device is not supported. But Odin detects my device and says "Added!!". I am currently downloading the stock firmware for my device from Sammobile and i plan to flash it using Odin.
- Will putting the firmware file in the AP section of odin and clicking start work to fix the problem? (I do not care if i will loose data)
- If this will not work is there anything else that i can do? I can't take it to repair because Knox is tripped and i do not have my receipt. If my phone is bricked forever please tell me so i don't waste my time trying to fix it.
Thank you so much in advance! Any help would be extremely appreciated!!

Just flash stock firmware and you are good to go, if it wont boot turn it off, reboot to recovery(stock) and wipe data & factory reset, later you can again flash twrp and root but dont turn off OEM unlock.

What about when my j7 says custom binary blocked by frp lock(boot.img) secure fail:kernel. It will boot into recovery, and download. Factory wipe does nothing, so recovery mode is useless to me at the moment. my computer detects the phone enough to say Unknown USB device (Device Descriptor Request Failed) driver error as the label of the phone. No matter what mode I'm in. Drivers are up to date, odins good, usb port, computer, and data cords are all good. I've flashed other phones and hooked this one up to another pc to see that it says the same thing. How do I get the computer and/or odin to agree with my phone enough to pick it up as a good device?
I'll be making a video for this with the 7 inch tablet on Nov. 29th or 30th (depending on the time I have)
General Disclaimer: I'm not responsible if you brick your tablet. This is how I did it personally as other methods here didn't work for me. I have yet to test this method on a 7 inch, also do not have access to the Surf variants. This has only been tested on the 10.1 inch with the keyboard. Will update when I test with the 7 inch.
What's Needed:
MTK Fastboot Drivers: https://online.mediatek.com/Public Documents/MTK_Android_USB_Driver.zip
Magisk Manager Canary: https://forum.xda-developers.com/apps/magisk/dev-magisk-canary-channel-bleeding-edge-t3839337
Stock Boot Image: https://forum.xda-developers.com/wa...eral/stock-stock-backups-images-otas-t3998227
ADB and Fastboot: https://www.xda-developers.com/what-is-adb/
Prerequisites:
Personally, I had issues getting my PC to recognize the tablets in Fastboot mode. The drivers wouldn't install. This might be optional for some of you, but I thought I'd include it just in case.
Installing MTK Fastboot Drivers from the link above
If you plugin your device in fastboot mode and your PC doesn't recognize it, follow these steps. If it did, skip this part.
1.) Download the drivers above and unzip the Zip file somewhere on your PC (desktop or My Documents is easiest)
2.) Boot your Tablet into Fastboot Mode by holding Vol + and Power, then select Fastboot from the Menu
*NOTE* There is a bug with these tablet's that the volume buttons are mislabeled. Really dumb, but I guess that's why they were 55 bucks for the 10 inch on black friday
3.) Plug the device into your PC and open Device Manager by pressing WinKey+R and typing devmgmt.msc, hit Enter
4.) If there's an Other Device listed called Android, follow these steps. If it isn't there, follow the next set of steps
5.) Open a Command Prompt window as Admin and type the following command
Code:
bcdedit.exe /set nointegritychecks on
6.) Hit enter, then restart your PC
7.) Once the PC is restarted, make sure your tablet is connected in Fastboot mode and open Device Manager again
8.) Right click Android under Other Devices and select Update Drivers
9.) Click the Browse my Computer for driver software button and select the MTK Folder you extracted from the download link above
10.) From there, you can open command prompt, type fastboot devices and see if your tablet shows up and move on to root!
Unlocking your Bootloader
From here, you can unlock your bootloader very easily to Root your device
This will wipe all data off the tablet!
0.) Enable OEM Unlock and USB Debugging on the tablet by going to Settings->About and tap Build Number 7 times. From here, enter the new Developer Options that unlock and turn on OEM Unlock and USB Debugging.
1.) Boot your tablet into Fastboot mode and connect it to your PC
2.) Open a Command Prompt window and type the following command, then hit enter
Code:
fastboot flashing unlock
3.) Follow the instructions on screen to unlock your bootloader
4.) Now Boot your device and we'll move on to making a rooted Boot Image
Creating a Rooted Boot Image with Magisk Manager
0.) Make sure you already have Wifi setup and connected before the first time you open Magisk Manager on your device! Make sure it auto connects as well
1.) Download Magisk Manager Canary from the link above
2.) Install it to your device
3.) Download boot Image from the Stock Boot Image part of the Prerequisites above and put the boot.img on your devices internal memory
4.) Open Magisk Manager and select Install Magisk
5.) Select Patch File and select the boot.img from your internal storage
6.) Once its done patching the image, take magisk_patched.img from the downloads folder of your device and move it onto your PC
7.) Boot your tablet into Fastboot mode and plug it into your PC
8.) Open Command Prompt and type the following command and hit enter (make sure you know your magisk_patched.img file location)
Code:
fastboot flash boot magisk_patched.img
9.) Reboot the device and you'll be Rooted!
Optional Steps like Modules and Debloating
My basic debloat script: https://forum.xda-developers.com/wa...s-general/root-walmart-bloat-remover-t4011639
Will be testing GSI roms on the spare 7 inch and will list those here
Recommended Magisk Modules:
Viper4Android Legacy
FDE.AI
MagiskHide Props Config
Systemless Hosts
Youtube Vanced Black
Magisk Setting to Enable:
Magisk Hide
Rename Magisk Manager App (keeps app from detecting magisk root)
Credits:
Myself for this root method @byproxy for reminding me to add the steps for OEM Unlock and enabling wifi before opening Magisk Manager for the first time
I'll start this off saying i'm an amateur at this, but I cannot for the life of me get an option to show up in magisk to patch the boot image even though it's on my 7" tablet. Any thoughts?
The bootloader was unlocked and it was successful so that's not the issue.
Are you online? I had the same problem.

Sorry, been a busy few days, but make sure you're connected to Wifi, close Magisk Manager, then reopen it and you'll be good to go!
Onn 8" walmart tablet
I purchased the 8" Onn walmart tablet second hand from a store called dirt cheap. Box didnt look to be opened but it had been. The tablet had been setup with someones gmail account that i do not know. The tablet was for a 4yo girl to use to learn preschool. Is there just any simple way to remove this google FRP lock ? I dont care if i lose the info on it as its not mine. I just want her to be able to use the tablet. Any help would be much appreciated please

Forced factory reset should do it. There is small pin hole near the power button. I believe pressing this hidden button(with a Sim card ejector, or paper clip).
If pressing does not do anything. Maybe press the button then hold power button too

Thank you for responding so fast. I've boot into recovery mode /wiped everything...its back to factory. The pinhole reset button does nothing other than reboot it . Ive tried all combos to with the reset button but nothing. Also i've read that its possible to use odin? if i can get it into download mode.
Ive downloaded the stock rom posted on an sdcard wondering if i can possibly update in recovery mode? Im sorta a newb at this stuff. I've been reading for 4 days on this matter. I've practiced a root on an old tablet with success. I guess at this point unless i can sell it as is giving the customer that it has this frp lock on it. If the know how to fix it so be it. Im not sure there is a working solution for frp bypass on these tablets.

This is an mtk device not Samsung. So there is no Odin or download mode. There is spflash tool, and preloader.
And if you flash firmware (with default frp partition) then frp lock is cleared.
But you will have to find that file. It maybe in the stock firmwares that are shared, I do not know.
EDIT:
i was having issues but figure it out. maybe it should be so common knowledge that it shouldn't need to be included as a step, but since i don't do this THAT often i didn't think about it and it took me a bit to figure out why i was having issues.
once you get your computer to recognize your device (mine did without needing to mess with any drivers) you need to first make sure to got into the tablet settings -> about and then tap on the build number 7 times to access developer options. then you need to go into developer options and turn on OEM Unlocking & USB Debugging.
THEN follow the guide to unlock bootloader.
then (since the tablet is factory reset once you unlock) do the above AGAIN to turn USB Debugging back on after you reboot.
also note that you need to have an internet connection on the tablet to utilize magisk. once you got all that square, then continue on with steps for full root.
hope that helps!

I was able to remove FRP lock on one of mine by flashing the stock rom with SP Flash Tool. I used the full wipe and download selection with every partition selected including boot.
no worries! i didn't think about it either until i was having issues. thanks for the tutorial... it was super helpful!! btw it definitely works on the 8" tablet.
Hello! I'm new to all of this, but what I'm trying to accomplish is removing the Google account from this tablet and putting a new image on the ONA19TB002, ONA19TB003, ONA19TB007, Surf 7 and 10 tablets. I followed all of the steps as far as installing the drivers. I had to go through hoops to get the MediaTek Drivers installed, but I have a "warning" cone by it. I haven't been able to find any resolution to this. Any help would be appreciated. I' have a Windows 10 64-bit system that I'm using and the tablet I'm specifically working on at the moment is the ONN ONA19TB003 tablet. The tablet is not being recognized by my laptop when I run the 'fastboot devices' command in PowerShell. Is there something that I'm missing? Any help would be appreciated.

Personally, I avoid PowerShell at all costs. This kinda stuff has always just seemed to work better with CMD.exe instead of Powershell.
These tablets are kind of a nightmare for this. If you've done the mediatek drivers and still have the warning cone icon, I'm not sure what's next as I haven't hit that wall myself. All I can maybe recommend is right click delete drivers in Device Manager, then start over with the driver install
Removing the Google Account would be needing a FRP Bypass. Someone above stated "I was able to remove FRP lock on one of mine by flashing the stock rom with SP Flash Tool. I used the full wipe and download selection with every partition selected including boot. " so if you can get it recognized, try that

Ok, thank you! This is a shot in the dark, but in order for ADB to work, USB debugging has to be enabled. I can't do that as the tablet is locked by FRP and I have looked countless times on Google and MSN to see if it's possible. Do you have any tips for that?
I don't know what I'm doing wrong, but for some reason I can't seem to get. The tablet to stay in fastboot mode. It just says waiting for device.

Sorry for late reply. Been away from home with work. When fastboot mode indicates "waiting for device," it generally means that your device is not properly communicating with your PC or laptop. This is nearly always due to missing or incorrect drivers 9n your computer. There are several comprehensive guides here on XDA for installing necessary ADB & Fastboot drivers.

when you mean patch boot img do mean to unzip file on onn 8
Hello...
I am looking for a working way to root my SM-T555
The device is running android 7.1.1;
base ver. "T555XXU1CQHA";
build ver. "NMF26X.T555XXU1CRG1";
Samsung experience 8.5;
Android security patch August 2017.
So far, the several attempts I made using every T55X related software I found in this website have been unsuccessful.
It would seem that the rooting software available is for "Marshmallow only", thus not Nougat specific,
though I read some comments stating that the TWRP made for MM worked on Nougat too and, after that, Magisk would/could do the job...
So I gave it a try but, after installing the recovery, my tablet got stuck every time: refused to boot normally
and if I turned it off, long pressing the power key, I couldn't turn it on again as if it was bricked.
Every time I had to re-start it in download mode and re-flash the original stock rom with Odin in order to have it working again.
On top of that, the "OEM unlock" key is not present in the developer mode list: none of the "date changing tricks" I found around the web seems to fit this model.
I am inclined to believe this "might" be the mother of my problems in rooting the device though, supposedly, the patches were not for Nougat, anyway...
The developer options page, once activated, can only be "turned off" ("greyed out") but cannot be deactivated;
while, on other devices, if you turn it off the page usually disappears after rebooting then you have to tap 7 times the build version, again, in order to make it appear.
I never had problems in rooting any of the phones and tablets I have /had, including an SM-T819 running Nougat 7.1.1,
thanks to the great job done by the coders in this community to whom I would like to express my appreciation for what they do for the benefit of us all.
But this thing seems to reject everything I throw at it and it's been the most stubborn "phone like object" I ever fought with.
So far I am the one loosing the fight... I wish some of you guys could give me the means to defeat it.
Thanks in advance to whoever may be available to help me out.
Flash TWRP, then install Magisk in TWRP.

thanks for your reply.
maybe my post was too long and boring so you didn't read it all
Of course I already tried the solutions posted in the page you suggested but they did not work.
not the autoroot files, not the recovery, etc...

If there is a TWRP file specific for my Nougat version available I'd be happy to give it a shot

Did you follow a guide when flashing TWRP? Did you unlock your bootloader?
You need to be clear and concise in your posts as yo what you did and how.

of course I did follow the guide by the book. also, the recovery appears to be installed properly, Odin showing a nice green PASS sign, but it doesn't work anyway
now about unlocking the bootloader, as I mentioned in my first post:
"the "OEM unlock" key is not present in the developer mode list: none of the "date changing tricks" I found around the web seems to fit this model.
I am inclined to believe this "might" be the mother of my problems in rooting the device"
every time I had to re install the system, so there clock want back to zero. Maybe I should be waiting for the allotted number of days to pass on order for the OEM unlock key to appear...
but before my first attempt to root the device, almost one month was past and the OEM unlock key wasn't there, notwithstanding...
I hope there was a chance that the bootloader was already unlocked...
to be concise (schematic):
tablet in download mode
untick auto reboot in Odin
AP loaded with "smt550_cf-autoroot.tar"
flash with Odin, OK, green sign PASS
reboot manually home+volume down+power,
then switch to volume up when screen becomes black
the Samsung logo appears and stays there indefinitely
So I turn the device off, long pressing the power key
then I try and turn on the tablet but does not turn on anymore,
not even pressing the power button for 30 second
then I press home+volume down+power again
to enter download mode and reinstall stock rom
(the same happens with
sm-t550_p550_p555_cf-autoroot.tar
or twrp_3.0.2-1_sm-t550_mm_7816.tar,
I also tried
twrp_3.1.1-1_sm-t355_251117
remark: none of them mentions T555 nougat)
Put your tablet in Download Mode and take a picture of the text at the upper left of the screen.

What process did you follow to unlock your bootloader?
Stop trying to use Autoroot. Let's figure out what we need to do to get TWRP on your device. Once we do that, you can flash Magisk in TWRP for root.
Please read this guide, sections 1 through 4 (don't worry about the GSI stuff) and tell me what you have or have not done.
ok, I wasn't able to do this:
Unlock Bootloader
Enable Developer Options and turn on OEM Unlocking
OEM Unlocking is missing in the list, as I mentioned in my previous posts
I tried the date change trick but it didn't work

This is the first step. You cannot flash custom or modified images if the bootloader is locked.
Connect to the Internet and check for updates in system options, then check Developer Options again.
I did that step too, several times:
the system found an update available
the first times I cancelled the download
then I downloaded the update without installing it
then I tried and installed it
no result at all the attempts: the OEM Unlock key does not appear in developer options

it is the first time I work on this specific device, so I couldn't tell: so far I couldn't find the OEM unlock option in the list
it never happened before on any of the several devices I have rooted in my life,
included another Samsung tablet SM-T819 running Nougat 7.1.1: the option was right there and all I had to do is tick it.
I used fastboot for other brands
I wish there was a way to use fastboot to unlock the bootloader on Samsung
if there is any I don't know it
adb is working, but when I give the "adb reboot fastboot" command, the tablet enters the download mode and fastboot does not see the tablet anymore from the computer

Samsung devices do not have a fastboot mode.
Since this is a Snapdragon device, it probably cannot be unlocked, especially if it was marketed in the US.
Only Exynos and international Snapdragon devices can be unlocked, unfortunately.

actually I am in Rome, Italy so I am quite positive it was marketed here...
is there a way to know for sure whether or not it is international?
the Samsung SM-T819 I am writing from has a snapdragon chip
but I had no problem unlocking/rooting it,
I bought both the devices here in Rome
now that's a mystery...

Usually the model number is a good indication with phones - the G908U vs G908N for example, but I don't see that being the case here
Have you tried signing into a Samsung or Google account on the device before checking for updates and looking for OEM Unlocking?

I did that too...
on a freshly installed rom:
I connected the internet thru wireless
signed into my Google account
completed the tablet configuration, etc
then I went and enable the developer options
no OEM Unlocking yet again...

You manually checked for an update too?
Did you try disconnecting from the Internet, disabling network time, and manually setting the time ahead 1 week?
