Motorola Says eFuse Doesn't Permanently Brick Phones
radicalpi writes "Motorola has responded to claims that eFuse is designed to brick your device if you attempt to mod it or install unauthorized bootloaders. Yes, the device will still not operate with unauthorized software, but it will only go into recovery mode until you reinstall the authorized software. According to Motorola: 'If a device attempts to boot with unapproved software, it will go into recovery mode, and can re-boot once approved software is re-installed.'"
There, fixed that for you. Bricked is permanent. Non-permanent "bricking" isn't bricking at all. If you can revive it, it was never bricked in the first place.
but I will decide what software is "authorized" to run on my phone!
No sale for you.

It all depends on how easy it is to reinstall the software. MOST "bricked" devices could be recovered at a service center with specialised equipment for a fee (that may not make it a cost effective proposition). If an end user can make the phone unusable but can't reverse the situation using the same equipment (or at least readily available affordable - as in a few bucks - equipment) I would still call it bricked even if it can be revived.
I have no idea if in this safe mode it's easy to install the authorised software. If it is easy I wouldn't call that bricked either. I'd just call it nasty DRM that I'll steer well clear of.

No. Bricked is forever, as defined by perception and ability -- both of which are subject to change.
A few years ago, I really fucked up a WRT54G when playing with software. I was going to throw it away, when I stumbled across a process for programming it using its JTAG interface and a parallel port. (Which worked fine.)
So was it a brick? The answer is simple, but flexible: It was a brick until I learned that it was possible for me to recover it, at which point it ceased to be a brick.
And now that I know how to deal with these issues, I can't successfully brick a WRT54G in the same fashion.
A dozen years ago, I fucked up a PC by flashing the wrong BIOS. Was it a brick? Again, it's a matter of perspective. In this particular case it was not a brick, though most folks would have reasonably considered it to be completely and totally bricked. Why was it not bricked for me? Because I already knew how to fix it: Enable shadow ROM on another computer, and plug the improperly-flashed BIOS into it hot. Then, just re-flash with the correct image, put the hardware back where it was, and move on with life.

Breaking in? It's not like it took prybars and hammers to open the thing. A WRT54G opens with a quick tug using no tools other than a pair of reasonably-strong hands.
Modifying the hardware? A little. But the JTAG header was right there on the board, IIRC it was even labeled. All I had to do was solder some pins to it to be able to plug a cable into it. And I could have done it without even going that far: after all, I just needed electrical continuity, and nowhere is it written that this must involve physical modification. (Soldering is easier for one individual device, but if I had a lot of them to fix I'd have come up with something less invasive.)
Breaking into the JTAG interface? To reprogram the PROM? You've gone off of the deep end. JTAG is a bog-standard and rather simple interface for dealing with flash at a low level. And PROMs aren't reprogrammable.
Another reason why the device was not bricked was that it was not physically damaged: No eFuse was blown, no parts had turned to smoke, and never was it in any particular danger. It just had a bad firmware load. In other words, it was experiencing a software problem. So I loaded new software that worked, once I learned how.

In other news, some layfolk also think that a PC with a crapfested install of Windows is bricked beyond help. This opinion is, of course, wrong. But it is based on their perspective and ability.
To use a car analogy: I have a dead GM 4L30E automatic transmission out back which died suddenly in my BMW. I fixed the car by replacing the transmission, which I knew how to do, so at no time was the whole car a brick. Now: Could the 4L30E be fixed? I guess so, but I don't know how to do that, so the tranny itself is still bricked. To someone else with different perspective and ability, it might be a quick fix, but that someone ain't me. If the day comes that I gain the ability to understand and fix automatic transmissions, or I give it to someone else who already understands these things, then it may cease being a brick.

Funny... cause the USB cable is in the box the phone came with.
"Have you ever thought about just turning off the TV, sitting down with your kids, and hitting them?"
you know what'd be fun? Let's spends several hours debating the "actual" meaning of a slang term. Can we do hella next? Because my friend says it means "really really" but he's just a fucking retard because I'm positive it means "really really really".
Too late. I don't know if I'll ever need to root my phone, but I want to know that I can. I was considering the Droid X and the HTC EVO 4G, and eFuse was the leading reason for selecting the HTC phone.
It's my phone, if I didn't want control, I would get an iPhone.
