Root Just get Blank screen on boot

[Austin_Yeahbaby]

Hi,

First post... please help...

I think I bricked my o2 desire within 1 day

My aim was to upgrade to froyo.

I set up my GoldCard no problem.

I then upgraded the RUU to the following with no problems

RUU_Bravo_HTC_WWE_1.21.405.2_Radio_32.36.00.28U_4.06.00.02_2_release_126984_signed

Now my phone boots with no display, I hear the boot music and the phone is seen by the RUU upgrade if I go back in but no display...

Please help..

Everything appears to work, buttons light up etc, but no screen???

 

[murphwiz]

After a tense 45 minutes of butt clenching, sorted!
Unbranded now using:
RUU_Bravo_HTC_WWE_1.21.405.2_T2_Radio_32.41.00.32U_4.08.00.09_release_137222_signed.exe31-Jul-2010 01:44 144M

Did you try the exact version I posted above, it's 1.21 and got my screen back into the land of the living!

There is also another thread with people having a similar issue;

http://androidforums.com/all-things...st-black-screen-vibrate-when-i-turn-help.html

Personally just used unrevoked mentioned on the one click root thread. Simple and no sim lock even on Orange who seem to have it in for people try not to have their Cr-apps.

You must use the RUU posted above, the one you used will not support SLCD desires.

 

[murphwiz]

How do you tell if it's SLCD or AMOLED, didn;t think the SLCD would be coming through yet?

 

[teppic74]

If you got your phone within the last couple of weeks it's very likely an SLCD one, if you got it more than a few weeks ago it's definitely AMOLED. There's no simple way to tell by looking unless you've got two to compare.

 

[Austin_Yeahbaby]

I did not know you needed a specific version for the SLCD screens.

I can't apply the above 1.21 version as I already applied the following to try and fix the problem

RUU_Bravo_H3G_UK_1.22.771.1_Radio_32.36.00.28U_4.06.00.02_2_release_127568_signed

Now I'm on 1.22 and can't dowgrade as I get Error [140] Bootloader Version Error.

How can I downgrade to the version you guys mention without having access to the screen?

check on the back of your box, in the description, mine says 3"7 inch AMOLED screen.

also, what bootloaders are you all working from? if its 0.83, then you may have problems..

Ahh mine just says 3.7" touch sensitive screen, so looks like slcd, hence the problems above!!
I think there was something in on of the links above, 'i bricked my flatmates desire' where they managed to get it back, however I'd be very tempted to take it back and plead ignorance and hope for the best?

P.s after all the angst of debranding, there's currently no froyo official upgrade for this software number, think it's on hold or something.

This RUU will work with SLCD desires:

http://shipped-roms.com/shipped/Bra...1.00.32U_4.08.00.09_release_137222_signed.exe

The others contain HBOOT 0.80 and will not work.

This is the latest version of stock HTC 2.1 software.

Wow do you know when this was released?

Will it work with HBOOT 0.83?

Official updates contain their own version of HBOOT and that gets installed, this one contains 0.83.

That's the one I used once I had cried over bricking my phone!
Never been so happy yo see a htc logo in my life when it did it's first reboot once flashing!

Do you know if it'll work with the Vodafone 1.24.161.3 ROM to downgrade to a stock HTC ROM?

You can try it (you will need a working goldcard). It won't do any harm if it fails to install.

However, because this contains 1.21.405.2 and the Vodafone update contains 1.24.161.3 it may think it's a downgrade and refuse to install.

You can still root the phone though and install a custom ROM (such as the rooted official 2.2 one, which has no branding).

 

[anoniemouse]

There is now a rooting method for people with a hboot of 0.83

[ROOT] Method for HBOOT 0.83/0.92 (SLCD phones) - xda-developers

There is also a fix if you have the dreaded black screen too

[SLCD-BRICK] Fix is here! - xda-developers

Yeah I know, but I think I'm going to wait and see how people get on with the root/downgrade for SLCD screens with the Vodafone firmware before I try it myself lol.

 

[teppic74]

Rooting has always worked on hboot 0.83, but custom recovery didn't work on SLCD desires until now.

If you have an SLCD desire, do not downgrade it unless using the RUU posted above. It will break the screen and force you to upgrade to stock 2.2 (and to do it without a working screen).

I was going to use the method stated here [ROOT] Method for HBOOT 0.83/0.92 (SLCD phones) - xda-developers. That should work shouldn't it?

 

[teppic74]

Some people have been unable to complete the steps without a screen to show what is happening. It is not worth the risk.

The steps for updating to FroYo are meant as a recovery for people who have killed their screen by downgrading.
