It tells me that my serial number is incorrect when I am certain that it's not

It seems that Samsung has no firmware for the SM J700T so it won't work.

I don't get the "Device Initialization" tab. It isn't present, but the drivers (correct- I think) are installed, it was being seen by Odin. Just trying to restore a buddies phone that is saying "Custom binary blocked by FRP Lock.
Any thoughts, ideas, solutions that anyone could share with me, please? And thank you......

Smart Switch says unsupported device.

Smart switch is garbage. Use updates by android aka updato on play store. Download firmware, extract on PC, flash with Odin.

Cfauto root works with sm-j700t 7.1.1 .
I updated while rooted just to see if it would brick or not . Didn't brick updated through smart switch.
Then reflashed the Cfauto sm-j700t and it worked.

U can just flash any root zip, auto root takes longer

Is the Verizon LG G2 (VS9803AA) running 5.0.2 Rootable?

I have spent the last day trying to root my Verizon LG G2 and have had no progress. Every utility I try seems to fail or freeze before finishing. Upon further investigation I found the the recovery that the Verizon G2 has doesn't have the option to flash the phone. In fact the only option it has is to factory reset the phone. I have also tried forcing the G2 to boot into recovery using adb reboot recovery. When I did this the phone rebooted to a black screen with an error message no command found. So I can't manual root it by flashing it. I have tried both versions of LG One Click Root but once the terminal or gui reached Looking for LG Serial Port nothing happens. It doesn't ask me to manual reboot into download mode or anything. From what I have been able to find, it would seem the Verizon G2 impossible to root.
Does anyone have any other methods or idea? This isn't my primary phone so if I screw it up is not a big deal (though I would prefer not to). I was also kinda curious if it is possible to flash a new recovery through download mode? As this seems like the only way I can alter the phone system.
Any help is appreciated.

why do you think is the cheapest version of LG G2 you can find? cant seem to root mine neither.

Download this:
LG One Click Root 1.3 (Graphic UI)
https://drive.google.com/open?id=0Bx...jMwN3Uzdm1rbkk
LG Verizon drivers
https://drive.google.com/open?id=0Bx...UdFZTVuTlUzVW8
Rooting LG G2 running Android 5.0.2 with LG One Click Root –Requires – USB drivers installed and Windows PC
1. Download and install ‘LG United Mobile Drivers’ on your Windows system.
2. Download ‘LG One Click Root’ file and extract it. Then install it.
3. ‘Enable USB Debugging‘ on your phone. To do so, go to Settings > General > About phone > Software information, tap Build number seven times and then go to Settings > Developer options and turn on USB debugging.
4. Connect the phone to computer via USB cable. (Select USB mode as MTP, NOT INSTALLER MODE, MTP only or it wont recognize it)
To confirm your device is connected over ADB interface, open ‘Device manager’ and it should show your phone as an Android device.
5. Run LG One Click Root tool and select ‘Start‘.
When it says ‘Waiting for device…’, get back to phone home screen and select OK for ‘Allow USB debugging?’
The phone will reboot at 45% and after rebooting when it says ‘Looking for LG serial port’, go to home screen again and select OK to Allow USB debugging.
6. The device will now reboot into ‘Download mode‘ (Firmware Update)
If the tool gets stuck at 90% on computer (0% on firmware update screen on phone) just restart the phone by long pressing power key while it’s connected to the computer, otherwise your device may get bricked. It should then show 100% and Done! . If not, repeat from step 5.
7. After it ends the process and the phone status bar goes to 100%, it reboots, let it load some seconds and now you should have Super user permissions now, you can see the app in the box too.

How to enter recovery mode Topway Ts8? Plz

Hi! I have a Topway ts8 product, how can I enter recovery mode? Help me please ?
This product only has a reset hole, and in addition does not have a physical key. I have tried many ways but cannot enter recovery mode.
I use Google Translate, so the grammar may be inaccurate, I hope everyone will be sympathetic and helpful

Hello. Did you manage?

Sorry to bring this topic on top again but does anyone have solution to enter recovery mode of this device? I tried to use five fingers to tap, swipe at left top corner, hold reset button… but doesn’t work. My HU is stuck at logo.
Thanks

What has been tried

Currently, I connected KEY2 line to ground, My screen displays "start update", I have a rom in USB but it doesn't recognize the rom, 3s later screen appears "update end".

I've resolved the problem "Device is stuck at logo and couldn't enter recovery mode" : check your Android head unit power cable, there is a line named KEY2. Connect this line to ground. reset your device (use reset hole) then on screen you will see : "update start", now you're in update mode. Make sure you plug your USB in with the firmware, all files will be installed automatically. Make sure you're using right firmware, if not 3s later, screen displays update end.

Unlock bootloader 8227l

I have a 8227 unit. I uptaded it with 9213 aj firmware ( Real Oreo 8.1), but I can´t install any twrp firmware. Rebooting on Fastboot mode, i can´t install it because the bootloader ,it´s lock, and it´s imposible try to unlock it, because the unit is onlly touch, no physical buttons (only reset pin). I try to flash directly with spFlash tools (only twrp recovery) i can flash but no access to twrp (logically)
Any Ideas for install twrp, or How can i unlock boot with other method?
In this unit for example, I only can access to spflash with a male-male without ground pin, and host config usb. For adb/fastboot can access with normal 4 pins and device conf usb
Thanks

Where did you find real android 8.1 for 9213aj? And how did you install it?

You can find It in russian forums as 4pda Sorry but i can't paste the link

Can you send a link by e-mail and instructions on how to install? [email protected]

SpFlash. and very important format + download all (included preloader) if your system is 6.0
A question...Is your bootloader lock ?. It´s not important for updated, but it is for install twrp
Please, Does anyone know how to unlock the bootloader without volume +?

Is there a difference in the operation of the radio on android 8? worth installing?

It´s faster than 6.0 and very smooth. I think that it improve sound (but it has same problem between 19-20 volume. Previously the problem appear between 17-18). If your system has sound`s processor (dsp) it has improvements as loudnes and equalizer inside this firm. I think that wifi and bluetooh conection is better
Maybe in other post we can continue this questions, But this post is about Bootloader in the 8227l demo

Oh No. Enter fast boot and unlock the bootloader is for can install twrp recovery (and root later if you want)
For install the fimware you must choose the scartter file from the new firmware and click in download all parts ( with select format all + download option), reboot the unit with 4 pin usb conected and host option config (3pin in my case and 12v external supply to the unit, others radios it´s not necessary). But the most important is make a full backup FIRST. When you completed your backup you will known how the unit must be conected

so I don't have to open the radio?

but I give up, I can't handle it

Android Allwinner T3P1 easyconn need help

Hi,
I am not sure what setting i have done or after updated system firmware. The easycon no longer working. Everytime i press the app icon, it went in and immediately kick out to the main icon screen.
Another issue is after updated the system firmware, the side touch panel lighting cannot be change colour. Floating button also gone missing.
Appreciate someone can help out.

I have t3_p1 1-16 Android 10 units. I reset it to factory settings. Screen mirror no longer works at all. Even the USB Car Play Dongle is not working. Is there a hero to offer a solution?

hello,
It happened to me when I updated my system, after system updating my air conditioner app stop working and also it's T3 P1 and I solved the problem.
The solution is to go to settings, car settings, extra settings ( pass 123456 ) then select car model or something related to model, then you will be getting into car selecting menu ( pic is attached for reference ).
Please be careful when choosing the car model, it should be exactly the same as yours.​after that you will get an APK downloading, also MCU update, system will be restarted automatically after updation, done
notice: your head unit should be connected to WiFi for the MCU updating process.
