[HTC Rezound] jrredho:
Good ghod what a state I've managed to get myself into: I've been unlocking/re-locking my phone (ROM: OTA ICS, S-On, Unlocked, Rooted) for right at a year now, but, during the recent OTA update push, I managed to get it into a state where it will no longer unlock. My (long, sorry) story follows...

I started receiving the recent OTA push two or three weeks ago. The problem is that I'd renamed the HTClinkifydispacher apk and odex files, and added a couple of things to /system/app/build.prop so the update would fail. Why was this such an immediate problem? Because I use my phone for an alarm clock and would wake up on random days to see it booted to recovery---after having overslept. Grrr.

Being the impulsive guy that I am, rather than just ask here how to stop the f$*kin' update, I found and saved the OTA.zip file to my sdcard, fixed the two problems I was having, re-locked the bootloader, and booted to recovery. Next, I *thought* I picked the OTA zip file to install... but I was wrong.

For at least one reason (I wanted to install a kernel with tun.ko installed so I could use a VPN network connection), I had a copy of SebastianFM's 1.4 overclocked kernel zip on my sdcard and mistakenly picked *it* instead of the OTA zip (hey, the fonts are small in Amon Ra). Well, that install failed, and, when I saw what I'd done, I thought "uh oh," so I rebooted the phone fully to see if I'd done any damage. None was apparent. So I moved on, once again re-booting into recovery and (this time successfully) installing the OTA zip.

Woo-hoo!

I thought I was golden, but I was wrong: Using my original unlock code and an up-to-date copy of the Android SDK on my linux box, I tried to reflash the unlocktoken partition using the fastboot command. My cursor froze/still freezes at something like "[0kb downloaded]..." It's almost like I've lost permission to write to that partition in the bootloader.

After the first sixteen times of trying various re-flashes of the August OTA, I thought "Gee, maybe it's something to do with the firmware," and since doing something is almost always worse than doing nothing (yes, that's what I meant to say), I did the only thing I could do: I flashed the Global Update RUU zip from October that I got off of Android Police's site. It's a great ROM; unfortunately, I still cannot unlock my bootloader. :(

In anticipation of some possible questions, let me add that

(1) I've factory reset any number of times;

(2) When I did the flashes, I immediately re-flashed a second time to ensure that the flashes took;

(3) When I connect my USB cable, I see "Fastboot USB" light up in the fastboot section of HBOOT.

(4) When I issue any other fastboot command, such as "fastboot devices" or "fastboot get_identifier_token", I get responses from the phone.

(5) Even though I have my original Unlock_code.bin file from HTCdev, I went through the whole unlock process from that site (sent a new identifier token; got the Unlock_code.bin back; tried "fastboot flash unlocktoken Unlock_code.bin") on two other occasions. Interestingly, the identifier_tokens would vary, but any new Unlock_code.bin files have all been identical---if the md5sum hash can be trusted to distinguish them.

Can anyone out there in expert-land help me figure out how to re-unlock my bootloader?! !? Beer can be involved. :)

Many thanks for your patience and kind consideration...

cheers,
