[How-to][ruu] Flash ruu.zip to factory

[czifraj2]

If you have some problem with your phone like me (Settings app fc always) you can download your RUU.zip and flash it.

If your bootloader unloced no problem no need to relock.
Go to download mode and type:

fastboot oem rebootRUU

Now your booted to the black HTC screen. Make sure your Rom.zip file is in your adb/fastboot folder

htc_fastboot flash zip Rom.zip

This takes a couple minutes and you will most likely get a error (pre-hboot update: please flush immediately) and maybe your phone reboot sometimes.
Make sure device is still in ruu mode(black HTC screen).
Let it run and it should finish this time

After completed :

 fastboot reboot

It will reboot to a fully stock build.
Just remember, anytime you get a "flush immediately" error, just make sure your still in ruu mode and reflash the zip.

The most common error is typically :
FAILED (remote: 90 hboot pre-update! please flush image again immediately )

Enjoy your stock phone again.

If you want to decrypt RUU you can use : HTC RUU Decrypt tool . You will got a system.img, boot.img, recovery.img etc...

Thank you. I was wondering how to flashing the zips.

Thanks OP.
I want to extract the stock boot and recovery from RUU but it appears the format of RUU provided here is different from the others.
Is it still possible to extract them?

And could this RUU rename to 2Q4DIMG.zip and place to sdcard and flash from device with download mode?

If y want to decrypt the RUU y need this : HTC RUU Decrypt tool
You can decrypt the ruu file and y can find the system.img, boot.img, recovery.img.

I think you can place to sdcard but i didn't try this.

Hi, I flashed the firmware from the microsd (fimware 1.10.400.23). As with htc 11 normal model, just rename the firmware file corresponding to the phone model in 2Q4DIMG.zip, put it in the sd card, start htc u11 plus in download mode and it's done. There is no need to have unlocked bootloader.

I tried to downgrade from 1.24.401.2 to 1.10.401.23 with the SD-card method (non root) because of wakelocks and the low percentage of Deep Sleep of screen time off (confirmed today by HTC Nordic today and that HTC are working on a new update. The support person didn't know any ETA).
Everything seems okay underway when flashing but after boot and finishing the setup procedure, Wifi, Google account etc. I'm still on 1.24.401.2. I used the 1.10.401.23 in the first post.

Have anyone else tried to downgrade with non root?

My HK model got an update today to 1.24.400.03 and devcheck is reporting 61% deep sleep.

I have had almost none since the update from 1.10 to 1.24.400.01. the .03 update seems to have solved this.

Downgrade has nothing to do with root. You have to be S-off.
