How do I unroot & go back to stock rom /recovery?

[elcidroyale]

I am on USA Mediapad 3 BTW-W09. I'm rooted, bootloader unlocked. I'd like to go to stock rom without root, bootloader locked. I want to sell this tablet like stock.

Thanks!

That's rather simple reflash the stock Rom that came with your phone... (Hint SRKTools) would be handy here..

I was able to relock the bootloader with that tool - thanks!

BUT now I have another problem. It reset and Huawei eRecovery popped up and said there was partition damage and asked to repair it. I said yes. Then it reboot but came to eRecovery screen again and asked to Download latest version and recovery. I did and it failed. Then the cycle starts over again. Won't boot.

What do you suggest now?

Quick question did you remove the "root", trwp before re-locking your BL.. this is why I suggested flashing your stock rom.. now go check out the bottom of this thread as it may be able you help you out..https://forum.xda-developers.com/mediapad-m3/help/bricked-mediapad-m3-t3746893

Ah yes I just saw this before you responded. I got the tool downloaded, got it to extract an update.zip that I found BUT there are two files missing. The CUST.img & USERDATA.img. Any ideas?

 

[elcidroyale]

I see I need update_data_full_hw.zip. Do you know where to find for USA? I found one for EU - does it matter?

I ****ed it now! I found the appropriate zips and uploaded through Huawei Media Tools. Then I have no bluetooth, keyboard or stock apps. Then I "downgraded" to MM I thought. Got some error message in Huawei Media Tools saying I flashed wrong rom. Now it is stuck on boot screen. Now what??

You need to stop while your ahead.. first off probably should have tried to stop you when you failed to mention what model you have as you haven't stated as much. and you just seem to be flash happy. All I will suggest now is either you can can try to recover it through Huawei HiSuite or take it to your local shop an let them re-flash it..

 

[elcidroyale]

damn you said it. I was FLASH HAPPY. No way to get into Hi Suite as it won't get out of boot logo. If I could get into the bootloader mode, I could reflash the correct files but can't do that. Oh well, lesson learned!

Ok..first get the correct Rom for your phone..don't do anything else till you do that.. the put you phone on the charger we don't want it to die and it needs to be charged.. now see if you can manually but your phone in fastboot mode either manually or by ADB commands .. and read up how to flash the rom that way..

WOW the gods have smiled down upon me and my and my tablet this morning! It was surely dead but I held power down and then plugged in cable then voila, fastboot mode!

Bootloader was locked so I unlocked it so I could flash correct files. I unlocked then it automatically reboot normal which was not good. The back to same frozen boot screen. I kept trying and couldn't get back into fastboot or any other useful mode. Then I went away and came back and tried again - hold down volume & plug cable - BOOM it work again.

I flashed the stock files and good news is back to square one with a mostly working tablet. Just same issue of no bluetooth, keyboard (I downloaded from web), stock apps missing & no "updater" section in settings.

Any fix for this? Any link to OFFICIAL stock rom for USA version?

Thanks for you help man!

Hit the thanks button.. try hooking it up to HiSuite and see if it will repair it through there.. (look here.. https://www.getdroidtips.com/huawei-mediapad-m3-stock-firmware/ ) if it has what you need you can fastboot or srktool it..

UPDATE FIX:

It was indeed bricked. Luckily it was under warranty so I sent it to Huawei Service Center and they sent me a brand new tablet in a few days.

Now back to square one with no 5ghz and SLOW AND ****TY 2.5ghz. ugh
