[Sprint HTC EVO 4G LTE] scottspa74:
This is my primary concern.

Quote from toastcfh in the one x forum TWRP thread. ......

no, USB mount does not work in recovery. It appears to be locked out in recovery mode. the workarounds to get it working are one of two things.

(1) fastboot boot awesomeRecovery.img (this works because fastboot then boots recovery on the boot/temporary partition. So the you're not actually in recovery mode

(2) Offmode (this works because again you're again not technically in recovery mode. It uses the recovery ramdisk, kernel, and binaries but its still not technically recovery.

On that note I've seen suggestions that it's possibly a recovery issue with cwm and twrp. Unfortunately it doesn't appear to be the case. If it were then in CWM u wouldn't have usb when u fastboot boot the recovery or in offmode (fair assumption since both these options use the same kernel, ramdisk and binaries as recovery?). Can it be fix? Not that i know of. It looks to me like a total radio or bootloader lockout from using USB in recovery. Which means on a radio or bootloader level USB is disabled in recovery mode.

On that note I think we should raise the point to HTC that this locking down of the device does not suite our needs.Key points of fail would be as follows.

(1) Can NOT flash the boot partition from recovery. I've personally contacted HTC on this numerous times and they seem to just not care. Responding with "It's a security issue" and so forth. I would love to know how this is a security issue of any sort. Every other Android device has this ability except HTC devices since they started the HTC unlock ordeal. It's utter fail IMHO and HTC should listen to our needs .

(2) Can NOT flash recovery or boot partitions from system. This issue is NOT a deal breaker and isn't so bad when it comes down to the nitty gritty. But since the issue above exists, flashing with applications like htc dumlock and such were our only options. These work around apps cant be used to flash now because of the lockpout from system and it wouldn't be such an issue if HTC didnt lock us out in recovery from flashing boot.

(3) Can NOT flash P*IMG.zips in hboot/bootloader anymore. For the unlocked device running a custom firmware this is a must. Specially when radio updates and such are needed from the OEM. We seen a big use of this on the Sensation when HTC updated the device from Gingerbread to Ice Cream Sandwich. The update required new hboots, radios, and partitioning to actually use. So in that instead of having to flash a RUU Which didn't exist the only choice was to flash a custom P*IMG.zip that included all the radios and images need to run the builds. At this point we can't update those image/partitions without flashing an RUU. This makes no since and doesn't seem to do anything but make things more difficult on the unlocker to customize and modify their device.

(4) If all the conditions above HAVE to exist. Then why not give us documentation or utilities to flash fimware.zips from recovery like HTC does? When HTC was the proud Nexus device there was full support and documentation available on how to flash firmware on their devices. This made anyone choosing an HTC device blessed with knowing that their device was not only open and unlocked, but when flashing firmware that it was being flashed correctly to Google and HTC's standards. This code has now been moved out of recovery since right before the move to edify scripting and moved to vendor/htc/ (not arguing this choice as thats where it belongs from a maintaining point of view). But the problem is that vendor/htc is proprietary now. Which means Documentation and support for flashing firmware correctly is not available and left to developers of recoveries for the community to figure out. One would think if HTC was standing behind us that they would step up and give us a PROPER/OPEN/REAL unlock, or if they cant for the lame excuse of security concerns, then give us the documentation and utilities to flash the boot and firmware partitions properly. I mean really... what is there to lose there?

(5) WHAT WAS THE POINT OF HTC UNLOCK? I was to reach out and except us as a community. It was to keep us from having to exploit their firmware and look for holes to gain control of a device we rightfully own. WHAT DID HTC UNLOCK DO? It unlocked the devices at first and with each new revision of the unlock it gets more locked down and harder for us to use it as intended. WHAT DOES THAT LEAD TO? It leads to us hoping someone will take the time out of their life and exploit HTC's firmware so we can have access and control of our devices. I mean, it's bad when u have people poking a device with a paperclip to get a device unlocked to avoid a official unlock.

Bottom line; I'm personally fed up with HTC's unlock. It's absolute crap! It does not serve the purpose it was intended and only makes things harder then they were before. As a devoted HTC customer it has me questioning if my next device will be an HTC. With all the other options that would allow me to spend less time trying to gain proper access to my device and more time actually having fun with it, why choose HTC? Everyone else is shying away for these same issues. Everyone with an HTC unlocked device waits for someone to exploit HTC's firmware and give them a proper unlock. Why not just choose a device without the locked down/unlock instead? IDK but HTC needs to step up and listen to us. Every HTC forum with an HTC Unlock is screaming for these issues to be fixed.

My call to HTC is to fix these issue and/or give us proper documentation on flashing firmware to our devices via custom recoveries. The boot flashing lockout is dumb, pointless, and in NO WAY a security threat AT ALL and is nothing more then a CRAP RESPONSE to something that they sould be working to correct, instead of ignoring. In the end its hurting HTC's relations with developers and is ultimately doing the opposite of what it's original intent.

HTC, PLEASE READ AND LISTEN!!!11ONEone

To everyone else, SPREAD THE WORD!!!ONEone
