Stuck in bootloader, please help!
I'm new here but right now I'm at my wits end here...
Backstory: I rooted my One and installed a ROM on it. However, a problem with the mic suddenly cropped up. Calling has been a pain and people say that they can hardly hear me. Speakerphone, however, works but it's annoying and inconvenient if I turn on my speakers every single time.
I decided to contact HTC again and asked for a replacement. I told them that there is something wrong with the mic of the phone. They were able to placed an on-site replacement. However, after 2 days, they sent me back an email saying that the problem lies "outside of the warranty" and the charge to get it back to working condition is $200. I thought it was ridiculous so I googled around and most on xda forums said that it is a hardware problem not a software one so I figured it's not a ROM problem.
So yesterday, when I got the phone back, it is unrepaired and worse, the volume buttons do not work at all...I am reluctant to send my phone back to HTC again because I know they will say that it is "out of warranty".
Stupid as I was, I tried to relock my One and S-On it again in order so that I can send my One back to HTC.
However, my One is stuck in bootloader mode.
On the top it says "Tampered", "LOCKED", and "Security Warning"
The HBOOT is 1.56 and it is S-ON.
The thing is, the volume buttons DO NOT work so I can't get into recovery mode using the normal method.
I can still use fastboot commands but the fastboot reboot command always send me back into the bootloader mode which is annoying. Because I can't get into recovery mode I can't use adb commands. So now, I think my phone is softbricked.
Would anyone be so kind and guide me through this? If anyone could help me I would be forever grateful.
