[RECOVERY][Y300]Return to complete STOCK instructions

33 posts in this topic

Posted (edited)

I struggled to get my phone back to stock as I could not get any update.app to work. I was finally able to achieve this through the help of others on this forum, and as promised, I have put together instructions and all the relevant files needed to get back to stock.

My phone is a UK phone with the following build number: Y300-0100V100R001C00B194, purchased in July 2013

So the stock recovery included is specifically for this, but maybe you can use it for your country.

For this to work you will have to have TWRP recovery already installed. Also, if anything goes wrong then please do not blame me, as I am only sharing what I know.

Download the Stock.7z file and extract it wherever you like.

The checksum for this file is:

MD5: BFA1D584BB8B629C0394EE775339E6A2

Do the following in order.

From the "ROM BACKUP - as from purchase" folder

1. Place the TWRP folder in the root of the micro SD - so your path on the micro SD card should look like \TWRP\BACKUPS\...........

Place these 2 files in the root of the micro SD

2. recovery-stock.zip

3. remove_su_binary.zip

4. Boot into TWRP recovery on the phone - If the phone is off then keep hold of the volume up and power button

5. Choose restore from micro SD

If this fails then you might have to run a TWRP backup of your phone first and then replace all the files it creates with the ones I have supplied. You will need to maintain the folder structure.

If SU needs to be removed

6. Install "remove_su_binary" from root of SD via TWRP

To remove TWRP

7. Install "recovery-stock.zip" from root of SD via TWRP

8. You now have Huawei Recovery - Boot into Huawei Recovery - Hold volume up and Power button till you see the Android and red triangle

9. Wipe cache partition

10. Wipe data/factory reset

11. Reboot

Done - Your phone should be exactly as it was when it came out the box, except for if you have unlocked your BootLoader, which you probably have.

BootLoader relock instructions

You need to know your unlock code, as it is the same code to relock.

Necessary drivers and adb have to be installed on your PC.

1. Boot into BootLoader - powered off, hold the volume down and power button for 10 sec.

2. Connect the phone to your PC

3. Open up command prompt

4. Navigate to ADB folder using the “cd” command, so your path might look like c:\adb\

5. Type "fastboot oem get-bootinfo" - without speech marks

6. Enter

7. Now you can see if your Bootloader is locked or unlocked

8. To relock

9. Type "fastboot oem relock xxxxxxxxxxx" - without speech marks and the "xxxxxxxx..." represents your unlock password

10. Enter

If anyone wants to add their suggestions/tips then please go ahead. Hope this helps someone. Edited by maniv

Make sure that in recovery mode you have selected the micro sd card and not the internal one.

Were you able to restore your phone. If you haven't then have a look at instruction number 5, I have made changes.

Is it possible to cleanly relock the bootloader?

sudo ./fastboot-linux oem get-bootinfo

returns LOCKED from new, UNLOCKED following official unlock and RELOCKED after following this guide.

 

As a result, although I have tried to restore to as-new condition for return under warranty, there is still evidence I've been messing.

I am not sure if there is anyway to get to a locked version rather than relocked. The above bootloader locking procedure is the same as that from Huawei's website.

If you do find a solution then please do post it on here.

Seems to be downloading for me. Unfortunately I do not have any other location to store the file, though I might be able to stick it on Google drive.

Hello maniv

I'm a newby and would like to ask where to get the recovery-stock.zip   I managed to find the remove_su_binary.zip

I am having problems with my Y300 bought in the UK it keeps trying to download an updated file of 127MB but fails and then tries to download again. it has downloaded about 7 times -- I have to keep it switched off to stop it. so your guide seems a godsend if I could only get the file downloads.

 

Thanks

albyhart

yesterday I unlocked bootloader and installed CM11.

 

now I just reverted back to everything stock and relocked bootloader.

 

I tried to flash dload of b189 and it said failed to update.

 

it's all because the splash screen has image of network provider and I don't like, I want the splash screen of general version like b189 have.
