[AT&T HTC One (M7)] isangaft220:
Hello all,

I am curious as to whether or not there is any other method to gain S-OFF on the HTC One with HBoot 1.61 other than Sunshine. I am a bit strapped for cash and AT&T may have managed to goof the network unlock code for this phone (I plan on using this phone on the T-Mobile network), which a good friend of mine who had just joined Project Fi (and therefore had been required to purchase a new phone) had kindly given to me to replace my old phone, which is aging and has its own problems... While we're waiting for AT&T to send us a replacement unlock code, I figured I would look into other methods of addressing this as I tend to have my smartphone unlocked and install whatever notably stable custom ROMs are available for such smartphones as I often use it both for development purposes and work calls and messages as I am a freelance developer and tech (among other things). My search came across the network unlock method for this phone requiring the phone to be in S-OFF and, eventually realizing that Sunshine costs $25 to utilize for such a purpose, I continued to dig deeper to look for another route to gain S-OFF on this phone, seemingly to no avail.

Therefore, in reality, I have three questions for any knowledgeable persons on this forum:

Is there any way of ascertaining the number of network unlock attempts used and remaining, or any way to reset the counter for such attempts? (Not 100% certain, but I seem to have found that a hard reset may reset the counter? Can anybody confirm this?)

Is there any specific firmware revision that needs to be used to even attempt to use a network unlock code on this phone, besides being stock? I.E. A maximum revision?

Is there any other method besides Sunshine to gain S-OFF (given this phone has HBoot 1.61), if all else fails? (I understand this is a $300 MSRP phone, however, as I stated before, I am quite short on cash at this time and need a decently working smartphone to continue working. I was already required to buy a new SIM card for $15 as it uses a micro-SIM as opposed to my old phone's mini-SIM and, though given the circumstances I feel I may end up obligated to go the Sunshine route, I would prefer to keep any expenses to a minimum if at all possible due to my current financial situation. I realize this amount may seem petty to some, but every person has their own restrictions given their own situations and I'm already in the midst of being forced to re-balance my own rather tight budget..)
