Lightbulb Alternate way to restore your phone to S-ON and stock

I've spent the last few days digging through the internet, looking for ways to get my Desire S back to S-ON after AlphaReveX S-OFF. The reason? I need to send it in for repair due to a birth defect.

I thought I'd share the path which turned out to be successful. Remember that there's always a risk that your phone will end up bricked as a result of procedures like this. I take no resonsibility for bricked devices, this is just a statment saying what worked for me. Good luck.

My initial setup was AlphaReveX S-OFF with Clockworkmod Recovery and LBC Mod. As the ARX HBOOT can't be overwritten by the HTC update program, it has to be replaced by a HBOOT that can. Luckily I found this thread in which Igl0 provides a pretty much tailor made HBOOT for this purpose:

The only problem: It couldn't be flashed in the bootloader (it would just return the message "parsed .."). After this I tried flashing through ADB, but for some reason it didn't work either. My third attempt was more fruitful - I successfully flashed engHBOOToverARX.img through fastboot (HTC drivers required which you probably already have).


Just to keep things simple I've made a zip which contains the files needed (except HTC drivers) to perform this flash. This guide assumes that you have already tried other methods and are familiar with related terms.

1. Connect phone to PC and navigate to fastboot
2. Download and extract the compressed folder attached to this post
3. I've composed a simple .bat (called "Click This") that will open a cmd prompt
and execute the command: fastboot flash hboot engHBOOToverARX.img.
4. Restart and enter HBOOT.

If the file was transferred and flashed correctly, the header text in HBOOT should now read "ENG HBOOT ...".

Now you can go ahead and flash a HTC stock RUU. It will overwrite other customisations such as a custom recovery. The HTC Update failed on my first attempt (file: RUU_Saga_HTC_Europe_1.28.401.1_Radio_20.28b.30.080 5U_38.03.02.11_M_release), but luckily I found another RUU that worked (RUU_Saga_HTC_Europe_1.47.401.4_Radio_20.28I.30.08 5 AU_3805.06.02.03_M_release_199410_signed). You can browse this great collection to find one that suits you:

As my first RUU installation failed partially, I was left with only the stock HBOOT and a non working recovery. Though, I found out that I could perform the next HTC Update attempt while in fastboot, and it was successful this time.
