What we must do first???
First we must downgrade from 6.0 if you have on your mt7 to 5.1.1
How do it???
Here i write how i do it :
1. I have b571 instaled and rooted
2. Downloaded custom.bin and oeminfo we copy to :
- Oeminfo copy to System(root)/dev/block/platform/hi_mci0/by-name and overwrite
- Custom.bin copy to System(root) /data and overwrite and set permission to 0775
3. Go back to System(root) and push search and write recovery ( it take some time to search )
4. When its finish you see folder recovery and open in new window
5. When it's open you see log and now you must delete this file
6. Now go to System(root)/data/system/dropbox and open ( delete all file in side )
7. Now go to System(root)/log/log-services and delete all folder
8. Open SrkTool via Administrator and go to unlock bootloader
9. When you unlock use Mobopx tool to flash stock recovery
10. When it's finish go to SuperSu and do it full unroot
11. Copy B500 update.app to dload in internal sdcard and flash using 3 bottom method
12. When you Have now B500 flash latest 5.1.1 and flash
13. Copy B300 update.app to dload in internal sdcard and flash using 3 bottom method
14. When you Have now B300 flash latest 4.4.2 and flash
15. When you have now latest 4.4.2 (in my case it's B137sp03) download first 4.4.2 for your mate7
16. When you download copy update.app to dload in internal sdcard and flash ( in my case it's b120sp04 )
17. When we have first 4.4.2 go to setting and then backup & reset and do it factory data reset and internal memory to.
18. When its boot go to setting/about phone and push 7 time on bulid number and go to developers option ( enable usb debugging )
19. Now open SrkTool and relock your bootloader
20 . When you have relocked we can go to next step
How change relock to locked bootloader
1. Open Dc Unlocker and create new count ( you must buy 4 credits )
2. When you have active your count open HCU Client and log there
3. When you login you has connect to server.
4. Now go to dialpad in your mate7 and write this code *#*#2846579#*#* push 1 and 2 ( change to Manufacture Mode and plug mate7 to your pc via usb cable )
5. In Hcu push Read Phone and when its connected go to unlock and push Lock Bootloader its take 1 min
6. When it's finish change Manufacture Mode to Hisuite Mode
7. Now go to SrkTool and push 7 then 5 and your phone go to fastboot mode and you see you have locked bootloader.
How Lock bootloader on latest full 6.0
1. When you have locked bootloader on your first 4.4.2 update to latest 4.4.2 using ota update
2. When it's Upodate you must unlock bootloade, reboot device, relock bootloader and lock bootloader (go to setting and then backup & reset and do it factory data reset and internal memory to.)
3. Now Flash latest 5.1.1 and do it that same unlock bootloade, reboot device, relock bootloader and lock bootloader (go to setting and then backup & reset and do it factory data reset and internal memory to.)
4. Now Flash first 6.0 full rom and do it that same unlock bootloade, reboot device, relock bootloader and lock bootloader
(go to setting and then backup & reset and do it factory data reset and internal memory to.)
5. Update to last 6.0 using Ota update and do it that same unlock bootloade, reboot device, relock bootloader and lock bootloader (go to setting and then backup & reset and do it factory data reset and internal memory to.)
Why we must unlock bootloader, relock and lock after full update rom???
Because all firmware have diffrent data formate in rom. When you lock bootloader all this information go to sevice when you use HCU Client.
If you want lock bootloader on 6.0 you must flash first Marshmallow (in my case it's B522 ) and do it format using backup & reset and do it factory data reset and internal memory to. Now you can relock first Marshmallow and update to last firmware and send your device to huawei services. Your warranty it's back and they repair your device
That all. Cheers
