How To | M8 Hong Kong | Downgrade with S-ON | To S-OFF

zeyarwynntun · Aug 19, 2014

Out of the Box, my M8 comes with 1.60.708.2.
I've been so upset that I can't go S-OFF with Firewater.
As for Sunshine method, in-app payment declined my credit cards (Myanmar).

And even with my Fav custom ROM, due to base OS difference, there were problems with boot time, boot logo, ...

Finally I found this site

http://bbs.gfan.com/android-7496959-1-1.html

These are what I did.

Stock Nandroid backup and Stock recoveries downloaded from this thread

http://xdaforums.com/showthread.php?t=2701376

1. I firstly restored to 1.60.708.2 by restoring Stock Nandroid from that thread via TWRP recovery.

2. Restored to Stock recovery from that thread.

3. Relocked the bootloader.

4. Download this and rename to HBOOT.zip
http://pan.baidu.com/share/link?shareid=2359888657&uk=622017286

Download this and rename to 0P6BIMG.zip
http://pan.baidu.com/share/link?shareid=2360886064&uk=622017286

5. Enter RUU mode by the command:

fastboot oem rebootRUU

Then flash HBOOT by

fastboot flash zip HBOOT.zip

6. Then, transfer the downloaded 0P6BIMG.zip to the root of mSD via Card Reader, then insert to the phone.

7. Reboot to bootloader by

fastboot reboot-bootloader

ROM flashing will start automatically.
It will take a long time to complete.

Then ur phone will boot up with 1.54.708.5 downgraded OS.

8. Then Unlock Bootloader.
9. Flash TWRP recovery.
10. Root with SU zip in TWRP.
11. Finally, use Firewater to get S-OFF.

DO IT WITH YOUR OWN RESPONSIBILITY

I've tried this method and now with SuperCID

Thanks for this. Worked a treat. I didn't need to downgrade the ROM just the bootloader and firewater worked!

It's a small price to pay, for less stress plus everything else is free on xda.

And yet you can afford this phone and a Sony Xperia Z2. O the mysteries.

I'm sorry, but I don't agree with you.

buying two devices doesn't make 25 dollar for a s-off (per device) cheap. Developers have been offering such services on XDA free for years. And there are always people who are willing to donate to appreciate their effort.

Remember there was a bounty thread where people were willing to pay up to 2 grand for s-off. But the devs asked us to pay a premium price per device, and that's just not in the spirit of XDA.

This is just my two cents. and you have every right to disagree with me.

Of course I am going to disagree. Another take-for-granted user.

will this work on all gsm unbranded m8's?

n1234d · Aug 20, 2014

Will this work for whelped users?

mdorrett · Aug 20, 2014

Any idea if it works with VZW? If so would I just RUU a stock ROM afterwards?

zeyarwynntun · Aug 20, 2014

I'm sorry friends.
I'm just an end user and just sharing my experience with my Hong Kong version of M8y with this method, which perfectly ok on downgrading and then S-Off'ing my Device.
I don't know it will work on other devices or not.

Anyway, mine was also a whelped device with 1.60.708.x.

Was it whelp, it has been patched, or whelp, no amount of flashing will help?

zeyarwynntun · Aug 21, 2014

Yes, patched.
And succeeded with this method.
Again, mine is Hong Kong version m8y.
