Hi folks!

My desire should arrive within a week or so. The past days i tried to collect as much data about getting full root-access with r/w access to /system.
We probably need a modified SSPL and a HardSPL. So far i've tried to contact cmonex, gauner1986 and haykuro to help us here.

So there is the first question to you (desire owners): Do we have jtag on the desire? Haykuro asked me; jtag is required otherwise testing is impossible.

UPDATE 1:
We found one device with r/w-access to /system, but we don't know where the security flag is set, so we can't set it to "normal" phones.
Adam235 is currently analyzing the dumped files.

UPDATE 2:
ahmgsk provided his recovery. Playtime.

Update 3:
Nand was unlocked for the EVO 4G. Maybe this helps us.

Update 4:
New root method, which should work with any new 2.1 HTC Phone, but we still don't have full write access to /system:

Well first off, good luck.

Don't we need schematics to know that or at the very least to rip apart the Desire to access motherboard and possibly find JTAG pins ?

Any less barbaric way? :<

Judging by the usb bricking showing the phones as qualcomm devices, and further by the mention of some Qualcomm development/debug tools mentioned on XDA, i'd say if anything, the JTAG connection is obtained via the USB port, and is activated by somehow switching the device to the debug mode.

Thanks for the input so far.

Over at modaco someone got a phone with full r/w access to system.

Anyone got an idea which addresses we need to dump the spl with pmemdump?
