And you need for changing OEMinfo on b182 TWRP for Android 6 (not the one from OP = for Android 7) Download it here: [url]https://www.androidfilehost.com/?fid=457095661767122229[/URL]

Steps:

1) Your Bootloader must be open! Backup important files or folder from your internal memory (cause it will be completely wiped, except external SD will stay untouched)

2) Firmware b182 must be in dload folder (update.app 3,06 GB) Take the one for your device For EVA-L09 download full Firmware b182: http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1079/g104/v63880/f1/full/update.zip

EVA-L19 can use same b182 - the Firmware works for both.

3) Unzipp oeminfo.emmc.zip - you get: oeminfo.emmc.win - this is the file what you need!

4) Store this file in following path on root of your external SD: \TWRP\BACKUPS\SNxxxxxxxxxxxxxx\C432\ (SNxxx folder must named with Serial Number of your phone and inside this folder copy the oeminfo.emmc.win

5) Enable Developer Options in Settings, go inside and enable OEM Unlock and USB-Debugging - after go to Advanced Settings /Security and allow "Unknown Sources"

6) Connect your Phone with USB to PC and wait until Windows installs the driver.

7) With Minimal ADB and Fastboot program for PC in administrative mode - boot the phone into fastboot mode and flash TWRP for Android 6.

(TWRP img must be in Minimal ADB and Fastboot Program Folder. You start the Program with right click as Administrator. You enter

adb devices

- you should get your SN and device. If on the screen pop up a request to allow connection, grant permission for always from this PC. Now:

adb reboot bootloder

-phone restart into Bootloader /Fastboot Mode. Bootloader must be unlocked and FRP unlocked.

You enter:

fastboot devices

- and get SN device, then

fastboot flash recovery Name-of-TWRP.img

8) If TWRP is succesful flashed disconnect USB from your Device and boot immidiatly after into TWRP. For this press Vol+ and Power Button. Stay holding this position until TWRP is booted (can take some minutes)

When TWRP is booted, allow Write Permissions for system.

9) In main menu and choose the button: RESTORE

10) Navigate to the C432 folder and restore oeminfo. (from folder C432 !) This changes oeminfo from b900 to c432!

11) Go back to main menu and reboot your phone - but not to system. You must press Vol+ and Vol- (in the middle) down until EMUI Software Installing begin and b182 will flashed again (it must be in dload folder!) If you see on screen text with red colour - ignore it, just press Vol+ and Vol- down, if it does not help, press also Power Button to reboot, but keep pressing Vol+ and Vol- because b182 must flashed again on this point!

12) If it was not successful and you receive after reboot a white screen and you will be promted to enter "the" password, dont worry, just use your password for Google. Phone reboots and make a factoryreset with EMUI low-level wipe. TWRP will be overwritten with Stock Recovery. Thats normal.

13) soon flashing again b182 was successful you reboot to system and perform from there another Factoryreset from settings /advanced settings /backup restore /Factoryreset with wipe of internal storage.

14) SIM Card must be inserted - you can leave it in your phone from beginning.

15) Just make a short setup and you will see: You receive now the OTA Update to Nougat :cowboy:
