sorry for the delay,i hadnt forgot about you
so ive eliminated the bad usb, unless all of them are... lol, (could be), i also dont know if its refurbished, and i havnt changed any images... thast 2/3 So should i call htc>>
that is prolly the best option,as long as you dont care about admitting to them that youre trying to unlock your bootloader,wich may void all or parts of your warranty,according to their disclaimer. this does NOT mean that you have no warranty,legitimate hardware issues are likely to be taken care of,and in all honesty,its very likely that neither sprint nor htc check for signs of unlocking/rooting/etc. when addressing warranty returns. vzw has admitted publicly that they do not check for root,only for the following:
1)the condition of the shipping packaging
2)overall physical condition of the device(scratches,nicks,etc)
3)that it powers on(or doesnt)
sprint is likely to be the same,as in reality we, as rooted users, are still in the minority of the entire phone using population. it would be very difficult to train staff at vzw,sprint,etc. to be able to check
all devices of all manufactures for signs of root when doing their inspections. its just not really worth their time. in the long run its cheaper/easier to just replace a few devices that they prolly shouldnt have.
having said that,the possibility is there,and is up to you to decide the amount of risk involved.
if the issue is hardware related,then the only solution for using htcdev unlock is to have them send you a device with everything matching. the thread i was refering to earlier,is
this one in the htc sensation forum. it was presumed his issue was a IMEI/ ESN mismatch,due to having the main board replaced.
unfortunately,he did not recieve much help from them. i dont mean to suggest to do anything dishonest,but if the phone has any issue you can find,you might call sprint(rather than htc) and argue with them to send you a replacement. hopefully you will get one that you can unlock.
Ok well thankyou, im assuming their has to be an alternative method for unlocking the bootloader, htcdev method has only been out so long...
unfortunately... no. htcdev unlock technically "works" for flashing roms(tho is IMO a PITA),and at the very least is a good,solid means of gaining root to make other exploits work.
as such,i dont think devs and hackers are spending nearly as much time looking for software temp root exploits. especially since the juopunut bear s-off method reverses the
relocked watermark,making it pretty much undetectable that you ever did anything(well,except for htc having your info on file from getting your unlock token)
todays newer,more complex devices are doing many more security checks,making it much harder for software exploits to be of much benefit. the emmc is write protected on s-on devices,so you need to disable that,but the typical ways of doing that have all been patched,and every partition is protected by another.
back in the old days,simply changing the main version on the phones misc partition would let the phone think it was "upgrading" to older firmware
we cannot do that now,because the phone checks the hboot version as well,and wont let you flash old software/firmware with a newer hboot.
you cannot modify hboot,becasue doing so breaks the htc signiture,casuing an immediate softbrick. you cant modify the partition thats checking hboot siginiture,as something else is checking that
and so on...
I see what your saying, that makes complete sense. Well, it must be a refurbished device... Ive heard of people doing like some sort of dbl brick force downgrade on the hboot, have you heard of anything like that? I mean, i know, it sounds completely absurd to temp brick your device to gain root access... im just curious.
prior to juopunut bear,hboot 1.4 or less was needed to s-off with revolutionary. clever user unknownforce on xda used a strategy to dowgrade hboot,based on the unbricking info/tool created by dexter93 for the sensation. basically you have to brick the phone in a specific way,wich will put the phones processor into a qualcom download mode,at wich point the tool can be used to recover the phone,but to a lower hboot than what you had.
the obvious dis-advantage,is that the soft brick you are required to create,could lead to an unrecoverable hard brick.
info on the dowgrade tool is here:

due to the obvious disadvantage,and the fact that we have no idea how the issue your phone has may affect this softbrick/downgrade process i cant in good feeling recomend that you try it.... as having a phone that would cooperate with htcdev,then running juopunut bear is a 100% more safe method of achieveing root/s-off.
I unfortunately can't offer any advice on that situation because I have never seen this before.
