I just read about
[ROM] [02-06] Primo-S - v4.1 [HTC One V port] Android 4.0.3 [Kernel 3.0] and it works fine on HTC Desire S.
First of all it's rom not RUU. if you want to know difference read tutorials and guides here.
You have HTCDev unlocked bootloader and installed 4ext recovery.My recommendation is to flash new 4ext recovery first(touch one) that I uploaded.
of that zip file.
To do this follow
step 3. in
[Guide] How to root, install EXT4 recovery and custom ROM on HBOOT 2.00.0002 just use
recovery.img from attachment down here.
And now for your problem.From what I know this is common problem on S-ON HTCDev unlocked phones.
After flashing new rom you have to flash boot.img from fastboot.
First open your
PrimoS-v4.1.zip then you will see file
boot.img.Extract it to
C:\android-tools.Get in boot by holding power button and volume down together.Connect USB and enter fastboot. (fastboot usb)
Go to start->run-> type cmd and press enter. A command prompt will now appear.
(just like step 4 in guide)
Type:
Code:
cd c:\android-tools [press enter]
fastboot devices [press enter]
this show if your phone is connected to computer
if you get nothing you are not connetced
if you get some info like ST9212IJKL then you type
fastboot flash boot boot.img [press enter]
you will see blue loading form in right upper corner of screen
very fast but that mean you flashed boot
When all this done reboot phone and you should get your rom started.Sometimes it takes up to 10min but no more then that.
If you don't get in like this then you have to go to recovery and wipe all except sd and flash rom again and follow step 4 in guide.
Try this then tell what you got.Good luck.
