is not problem in WP7.8... problem is in bootloader... Zune cant downgrade bootloader when roolback update...
only way is flashing with gold card and Y-USB cable SLSPL http://forum.xda-developers.com/showthread.php?t=1413694 and after that flash NoDo version http://forum.xda-developers.com/showthread.php?t=915827
but if you bricked bootloader you can forget all about this... maybe HTC service center can do jtag on your device and restore bootloader

Thanks dxdy for the goldcard method but I already know it I cannot wanted to do that any other method

New upgrade for HTC Titan and Interop unlock

So I have an HTC Titan and just saw an update available notice on my phone.
This is the second update available on my phone. I applied the first update last month and am now os version 7.10.7720.68, firmware revision number 1600.2200.10902.401, bootloader version 1.8.16001S.3(132000).
Should I stay away from this update if I want to wait for an interop unlock.

Bump since more people would have noticed update by now... Any feedback friends?

I just recieved my Titan and I seem to be on a later version of firmware and bootloader. Unfortuantey I have not been able to get interop unlock to work.
Other than that I have not real basis for comparison other than the fact that it is an awesome phone ...

'HTC desire s' not listed on htcdev.com

Hi all
Is it me, cuz im not seeing the 'desire s' listed on the htcdev.com as an option to unlock the boot loader?
All I want to do is root my stock Rom. Not interested in trying any other roms.
Sent from my HTC Desire S using xda premium
It's not listed but it works. Just select the bottom option "Other Supported Devices" and follow the procedure
Does this procedure get around s-on also ?
Concerns me why they haven't listed it.
Sent from my HTC Desire S using xda premium
No, your device will be s-on, but the bootloader will be unlocked. It's almost the same.
I have no clue why they haven't listed it either.....
Can you still root with s-on ?
Sent from my HTC Desire S using xda premium
After you unlock bootloader via htcdev.com, yes you can
Thanks for your help. One last question, how do you root the installed rom?

Look for SuperOneClick in here, it will easily root your rom
Sent from somewhere around the globe using XDA app on my HTC Desire S
I unlocked the bootloader via htcdev.com (operation was OKAY).
SuperOneClick 2.2 hangs at step 7.
I'm guessing that you have a hboot 2.00...
When u used HTC.dev to unlock your HTC desire s you need to Install cwm or 4ext and then you can flash any Rom you like.
After flashing your HTC with the new Rom you need to fastboot the boot.img to your device cause your device is not S-off.
An other option would be downgrading. Do a few searches and you will be fine.
Otherwise post back and I'll help you out.

Hello,
Thank you for your help.
Yes I have the HBOOT 2.00.002 - Android 2.3.5
In the post : http://forum.xda-developers.com/showthread.php?t=1390496
"dtronics" suggests 2 operations to do for s-offing for the Desire S :
1 - unlocking the bootloader (htcdev.com)
2 - using SuperOneClick 2.2
The second treatment hangs at 7th step.
Without downgrading the hboot (2.00.002):
If you have a link to a simple and complete documentation to doing s-OFF.
Thank you
Dos bootloader unlock deletes all personal apps, contacts, files or not?
Superoneclick 2.3.3 roots desire s?
Thx for help

I unlock bootloader and root, install recovery, then it deletes all contacts and file in internal storage, not delete file in sd card
In the drop down list choose other supported phones

What's better to do if I want to flash roms, htcdev unlock or S-OFF? I mean, do I have to do both, or just one, and what's better?
And what should I use, EXT4 recovery or ClockworkMod Recovery? Tnx
I would choose downgrading if necessary and S-OFF. The main disadvantages of the htcdev method are the loose of warranty and the need to flash manually the boot image every time you change the rom.
I personally like 4ext but CWM is also very good.
Next time you need some info gry to search the forum, this things were allready discussed.
As a mather of fact i don't think there's a thing left undiscussed in here.

[Q] updating to official ICS

Im a noob here i just wanted to know if i update my htc sensation 4g (on official 2.3.4 with locked bootloader and s-off) to official ics will i loose my carrier unock. I unlocked it using http://forum.xda-developers.com/showthread.php?t=1232107
Nope. . . Never loose carrier freedom after update
Before updating , I recommend get s off now in case if u want flashing in future .
Coz getting s off on ics ( include wire trick ) is verry difficult than gingerbread. .

rooting htc one help needed

any way of rooting htc one wihtout unlocking bootloader?
more over i read some where if i unlock bootloader i wnt get future updates as well as i may lose some apps in htc one?
does unlocking bootloader wipe all d date on phone?
if yes suggest me best tool to back up everything on pc?
thanx in advance
There is no way to root the HTC One without unlocking your bootloader. Also yes unlocking your bootloader will wipe all the data off your phone. About future updates as soon as you go back to your stock rom everything will be back to normal and you can get the updates. Some apps and features will not work because they need things like frameworks from the HTC Sense roms.
As long as you don't go to a custom rom all your feature should work but installing a custom rom is part of the fun.

**Press the thanks button if I have helped you.
What about s-off does it requires unlocked bootloader? Does it root?? Does it wipes away the data ???
