Current state of AT&T bootloader? topic

My partner is looking at getting a new phone, and we are looking around at different models. We want one that we will be able to upgrade and flash custom ROMs on for obvious reasons. For the AT&T model, what's the status of the bootloader? I have read that someone had an unlock method a few months ago, but I've also read that new models have an update that breaks that method. Also I have read that there is a safestrap method to install custom ROMs without having to unlock the bootloader.

Can someone summarize the status of the above for me? We would be buying a new one from AT&T. Would we be able to unlock the bootloader, or use safestrap?

Thanks!

[Q] Random Shutdowns. Reverts to previous phone state on reboot. topic

My AT&T HTC One (32 GB) that I bought day one keeps rebooting randomly.

From day one, I rooted, unlocked my bootloader, flashed CWM, and installed Android Revolution.
I've since updated up to AR 31.0 without any problem, and have been running that version for quite a few months.
I have never had any problems with Mike's roms on any of my other phones.

Recently, it reboots completely, even when I'm not touching it.
Once booted up, it will revert to a previous state. The same apps will begin to update, I will be notified of the same emails, voicemails, texts, etc.
If I touch it while all this happens, it will reboot again, and do all of the same things.
If I leave it alone until all of this occurs, I might have some luck using the phone in a stable state.

I've not installed anything new recently.
I run Seeder, a few Xposed tweaks, a couple of Sense Toolbox tweaks, and Tasker at root level, but all of these things have been running simultaneously without a problem for months.
This just started happening out of no where.

Again, running AR 31.0, Android 4.3, Sense 5.5. Random reboots.
Any ideas guys?

[Q] Trying to get to the state of LOCKED (bootloader) but I'm stuck on RELOCKED topic

I'm on full stock (recovery and rom) but on my bootloader it says ***relocked*** and I want to get back to locked so I can use my JUMP thing from T-mobile. Any tips on what i should do to get to say ***locked*** instead of ***relocked***

Xperia Arc S - battery drain in OFF state - suspect hardware topic

Hi there,

my problem is as shortly described in the topic.
The device drains between 50-190mA in an OFF state depending on the voltage applied.
I used a lab power supply to check it.

The procedure to measure it is:
0) perform repair using PC Companion - the device is completely clean
Model: LT18i
Android version: 4.0.4
Kernel: 2.6.32.9-perf
Build: 4.1.B.0.587
It has been upgraded from its factory version quite some time ago.
The drain problem started long after the upgrade.
1) Installed (just for formality): Battery Widget, Battery Stats Plus, OsmAnd, GPS Test, Total Commander
- the rest is usual bloatware that installs itself
1) switch off all possible functions (plane mode, WiFi OFF, BT OFF, ...)
- no alarms, no calendar notifications
2) power down the phone
3) take out battery, SIM card and SD card
4) connect power supply directly to ± battery connectors on the phone
5) no other cables connected (neither the battery)
6) apply voltage 4.2V (190mA) -> 3.0V (33mA) in 0.1V steps

Let me stress it again - the phone is in OFF state - no power button pressed, no attempt to boot it.
At this state I would consider 10mA normal, but definitaly not 200mA.

I have done a bit more measurements, but I don't think it is of use now.

As I mentioned above, the problem started suddenly, long after I upgraded to a newer OS version.
I noticed it since the phone started heating, which I could feel in the pocket.

Now, a bit about the heating. It seems that the source of it is a chip that I have identified as a Flash memory.
It sits around the top left under a metal shield when looking from the back of the phone,
after unscrewing the plastic mid-part. It is worm even in OFF state (no charger, just battery).
It gets very warm when the phone is ON and "unpleasantly" warm when there is some activity
(I actually played with the camera).

Otherwise the phone is fine. I haven't noticed any problems with it.
I use it as a navigation, SD card and SIM inserted, but no service (I mean the SIM card is inactive).

Now the actual question - is there a SW way (I mean without desoldering anything) to possibly
correct this problem? Unfortunately my suspicion is that some power management component
must have failed and it keeps delivering power.

Any help will be appreciated. It is still quite a nice device.
