I have to unlock my bootloader of redmi note 3 i got permission from xiaomi but when i used mi unlock tool to unlock bootloader but it is showing verific
ation error
It's a common error you might face. The solution is to enable oem unlock in developer options and USB debugging and go to i.mi.com and login in with your account to make sure that the device is shown online. Then go to fastboot and try unlocking. If it doesn't work, wait for some 3 days and try again.
Mine worked after 3 days.
this method worked for me (kenzo) when i was on V8.0.6.0.LHOMIDG MIUI8.
1- you need to switch from global stable to global developer rom, download the latest global developer rom on android lollipop(5.1).
unfortunately xda won't let me include links,so google this : miui_HMNote3ProGlobal_6.8.18_d0da79d09e_5.1.zip
2- after downloading the rom,rename the file name to Update.zip then copy to internal storage(in downloaded_rom folder).
3- open updater app, select choose update package, go to downloaded_rom folder and select Update.zip. It will verify your rom and install it.
4- download the latest global developer rom from en miui , repeat the steps 2 and 3.
5- sign in to your mi account on your device(enable find device),also on i.mi.com(to check your device). enable developer options, then enable OEM unlocking and USB debugging.
also check your status in developer options>unlock bootloader(I forgot the exact name of this section)
6- download the latest version of MIFlashUnlock tool and log into your account
7- turn off your device and go to fastboot (press and hold volume - and power button at the same time), connect your device to your PC, click unlock(on MIFlashUnlock tool), after your bootloader successfully unlocked, click on reboot.
also there is no need to wait after receiving your permission, it worked for me after a few hours of searching for solutions and if I knew this method in the first place, I don't think there would be a problem right after receiving my permission to unlock the bootloader.
Attention .. !! Make sure you have received a message to unlock the bootloader !!!
It worked for global rom 7.2.1.6 beta !!! You can try on the position rom any liability for any error so long as this method at your own responsibility !!
The first step: remove MI ACCOUNT you and reset your mobile phone ..
2 - turn off the only time after the initial boot, (do any setting and turn off your device).
3 - unplug your sim card and turn it back on without any sim card inside.
4 - continue to use the wifi connection just proceedings in the initial setup ..
5 - after entry to the home screen, Your new MI ACCOUNT Your input settings
6 - turn the setting developer
7 - Turn OEM UNLOCK and turn on usb debbuging (Do not try to add an account in setting the developer to see mi unlock status) !!
8 - after the entry into fastboot mode
9 - The right way miflashunlock
10 - try to expect the device you will be able to open bootloader
After i flash my phone the OEM is not showing. I waited for 7 days but still it's not showing, i guess it's because there's no IMEI and Baseband version is UNKNOWN. Now i can't root, write EFS or install custom rom. Please help me guys if you any idea to fix this problem on my galaxy A520f (2017)

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.

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!

B.S! Done that like 10 times now, no OEM option still.. I have all the passwords and everything, still can't get it rooted ...
Hello i was needing the stock firmware to my s21 SM-A215U A215USQS6BUL1 TMK im actually try to downgrade it for android 11 to android 10 and if possible put TWRP on it if anyone could help me out i would really appreciate it thank you
Hello all. I have a G570Y which was accidentally updated to the August 2020 security patch system. I can't downgrade the firmware to the previous version because this version has changed the binary to U3 (earlier version U2).
You also won't find OEM Unlock Toggle in Developer Options or it is called RMM / KG State set to Prenormal on this new firmware.
However I have managed to make this device ROOT. This is how I do it.
STEP 1 - Bring up the OEM Unlock Toggle
URGENT !
You have to connect to the network and ignore / disable Samsung Gift applications
Show Developer options by opening the Settings menu> About phone> Software information> Tab 7x on the Build number and returning to the Settings menu, the Developer options menu is under the About phone menu.
Select the General management menu> Date and time> Turn off the Automatic date and time option, then set the date manually. Shift the month counted 3 times backward, ignore the date, choose the one you like (This method works best without frustration)
Select the Software Update menu then turn off the Download update automatically option, then restart your phone.
Open the Settings menu> Developer options> OEM Unlock is visible. Repeat for the OEM Unlock process by sliding the toggle.
If it doesn't appear, repeat no, 1,2,4. When it appears you can continue to the next step.
STEP 2 - Flash Root Kernel
URGENT !
You must backup all your internal data before doing this process.
i found a halabtech website which uploads root kernels for G570 F/M/Y series with U3 binary. You must use ODIN to flash this file in AP.
Link download :
Root Kernel G570M - Odin
Root Kernel G570F - Odin
Root Kernel G570Y - Odin
Download the latest version of Odin here:
Odin3-v3.14.4.zip
After installing the Root Kernel you will find a long booting and a black message appears on the device screen saying that there is activity without permission, wait a few moments until you can press the Reset button at the bottom of the screen. The device will reboot and erase all data.
After that you must install Magisk Manager and update the latest version of Magisk Root.
STEP 3 - Install TWRP
Download the latest version here:
TWRP - J5 Prime
Download RMM State Fix 8.1 and 9.x OEM Unlock Fix here:
RMM_Bypass_v3_corsicanu.zip
Reboot phone to Bootloader (hold Vol Down + Home + Power button)
Open Odin then enter the TWRP file in the AP box, untick Auto Reboot on the Odin Option menu. Click the Start button.
Turn off the device then enter TWRP (hold down the Vol Up + Home + Power button), select the Wipe menu> Format Data. Then back to the TWRP start menu and select Reboot> Recovery. (This is because the phone's internal sdcard is not readable / 0 mb)
You can only copy files and flash RMM State Fix 8.1 and 9.x OEM Unlock Fix after reading the internal sdcard in TWRP.
I've managed to make a permanent ROOT on the G570Y and removed all the bloatware. I hope this helps all of you.
