Hello!
I'm using Samsung Galaxy Grand 2 (SM-G7105) and I want to unlock my bootloader but adb and fastboot don't recognize my phone while it is in download mode
Yes,i tried re-installing drivers and changing usb ports but it still doesn't work
Here is what the cmd is telling me:
C:\adb>adb devices
List of devices attached
0962d261 device
C:\adb>adb reboot-bootloader
C:\adb>adb devices

For interacting with Samsung devices in download mode Odin is usually the tool that is involved. Do you know for sure that your device doesn't come with a already unlocked bootloader? Are you trying to install a custom ROM? If you can provide me with more information I can help you more !

Yes,i am trying to install this ROM
Odin can actually detect my phone while in download mode,but fastboot and adb cannot
My real problem is when i try to install the ROM (i'm using TWRP recovery) it gets stuck at "Patching system image unconditionally" and the solution that i found on the internet is to unlock my bootloader

According to CPU-Z
Model: T07 (t07_ww)
Manufacturer: acer
android version: 6.0
Api level: 23
Kernel: 3.18.19+(1469620262)
Would these suffice?

Do you have any any custom recoveries for your phone so we can flash a supersu.zip?
If not could you boot this recoveries I repeat boot not flash or install.
How to Boot into recovery without flashing:https://aubykhan.wordpress.com/2013...t-into-twrp-or-cwm-recovery-without-flashing/
Custom Recovery:https://www.androidfilehost.com/?fid=24591023225178597
The custom recovery may not be for your phone but I have tried booting random recoveries to my phone similar to its specs and it worked!

Not the device but maybe the recovery but since you are booting it and not flashing it maybe it won't.I did this procedure to my phone but the 3g T06 model of acer liquid zest and it worked. Well I changed some links so that the recovery would be compatible for your chipset which is mt6735 and kernel 3.18.19+
PS.you need unlocked bootloader and developer options on for oem unlocking
Thank you, i will try that as soon as possible, although, whats the way to boot in bootloader in acer device?

Turn off phone then hold power button and up button at the same time or you can boot in fastboot using ADB commands.
Make sure you have an unlocked bootloader and good luck!
PS. Unlocking bootloader formats the phone

That can be caused if you dont have drivers installed and are you sure you have developer options on and usb debugging on? Also bootloader unlocked?
Hmm can you give me a picture of the procedure?
Pic of the device and the pc.
The picture of the device while the pc is saying waiting device and vice versa

Every Odin version I use with every TWRP tar file I try to use doesn't work. They either Fail or Odin stops responding when I try to load the tar file into the AP.

You can check bootloader with dialer (search it).
Of phone has fastboot mode you can check bootloader with fastboot commands (search it too)

I tried a some other steps. Tried using the video on youtube on a tut. When I get to the oem unlock I just get stuck with a msg sayng "waiting for any device" my device is plugged in, from what I know I have updated the samsung drivers (from previous attempt of other methods) the adb bootloader cmd did put my phone into fastboot mode
(White box, blue arrow point down with a straight line under the point)
(Blue screen with Downloading...)
do not turn off target
What am I missing here?
I tried rooting TWRP 3.2.3. with Odin on the phone again and it still failed
Does anyone else have any more insight to a possible solution?

Witch android you are?
I tried to much with installing diffent ROMs and now nothing's working anymore.
My poco starts only to fastboot but I can't connect with adb. Any other possibilities?
Drivers are all ok on the PC, because my second poco is normaly recognised.
Thanks for help.
Given unlocked bootloader, If you can only boot to fastboot maybe your recovery was deleted. You probably need to install twrp:
1.get twrp here:
https://forum.xda-developers.com/poco-f1/how-to/recovery-official-twrp-t3883736
2. If fastboot is working then:
https://www.xda-developers.com/how-to-install-twrp/
If you can boot to twrp then flash a custom rom
Note that I'm unsure if above will work, only guessed
Can't flash twrp because in adb mode it shows < waiting for any device >

I am sorry to say that but I guess nothing could be done to fix your tablet. I would be happy to proven wrong and see some solutions in this thread.
@XX_MRBEAN_XX
The mostly overlooked command
Code:
adb sideload <ROM / MOD>
may help: Get device's Stock ROM and flash it this way.

1. Looks to me that the ADB-driver you use isn't suitable: Download and install the correct driver for your Lenovo. tab:
https://devsjournal.com/download-lenovo-usb-drivers-adb.html
2. Wondering why then you didn't flash this Stock ROM by means of Fastboot ?
Code:
fastboot devices
fastboot erase boot
fastboot erase system
fastboot erase cache
fastboot erase userdata
fastboot flashall <STOCK-ROM-IMG>
fastboot reboot

Oh man
become familiar with Fastboot-driver and its subcommands available!!!
Anyway, unlock tab's boot-loader by means of Fastboot before you carry out the commands previously shown
Code:
fastboot devices
fastboot OEM unlock
FYI: I no longer participate with this thread.

To rescue a bricked Lenovo device, download their LMSA tool to a Windows PC. Use the Rescue option.
Have a look on the TWRP thread for the unlock commands. They will only work if you had already enabled Developer Options and OEM unlocking before the device bricked.

thank you for your help my bootloader wasn't unlock it is now thanks a lot
It appears your device's bootloader is locked. Try:
fastboot oem unlock
fastboot flashing unlock
If that doesn't help, search for a guide on how to unlock bootloader for your specific brand.
It also looks like don't really know what you are doing. Make sure you are following trusted guide. If no, I'll be happy to help.

well i did installed custom roms few time but i dont know much, i did unlock bootloader now the problem is i do install custom recovery twrp and it do installed and rom manager shows that custom recovery is installed but pressing volume down + power button just shows fastboot logo and it restart my phone, and with command "
adb reboot bootloader" i am able to boot into fastboot mood and when i go to recovery from their it open stock recovery instead of twrp
Stolen from my guide:
7. Go into fastboot mode
8. fastboot flash recovery recovery.img
9. fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
10. fastboot reboot recovery
12. Sometimes recovery doesn't want to stick as a permanent one. To test it, hold the power button and select "Reboot to recovery". If you reboot to TWRP, you can move on, but if you reboot to stock one, flash recovery using fastboot again and from recovery flash recovery again (sounds crazy, right?). I won't give you instructions on this, research it yourself. Make sure guide you will find is for your device and your recovery.
