[Hardware Hacking General] dannysauer:
I'm working on a system for my vehicle which needs a device that has Bluetooth and at least one (preferably a couple) "thing" (GPIO or useless LED or whatever) that I can have an application set and hold to either high or low. The device needs its own battery, so that it can operate without draining the vehicle's battery. What I'm ultimately trying to do, among other things, is to use Blueooth proximity detection to unlock my car - and a bunch of other things while the car's on. Because cell phones (and, to a lesser extent, tablets) already have batteries that will last for days with all the radios shut down, the screen off, apps suspended, and the CPU in a low-power mode, that seems an ideal approach - made better because older phones cost near-nothing on eBay. :) I don't have to have a visible display, but a working touchscreen would simplify a lot of other things I'd like to do.

But it seems darn near impossible to figure out what device would be be appropriate. Specifically, I haven't been able to find a good way to identify what devices have something like unused / repurposable GPIOs. I don't know if I need to just repurpose an LED, or if there are phones (or tablets) which already have something to interface with. Or if there are newer devices that I can use something like a USB serial port on, or if I just play a "sound" which makes the audio output seem to be "on", or what. The important thing is that the phone/tablet has to be self-contained, as charger power will be disconnected when the vehicle is off - and it'd be best if I could get an extended-use battery for this device which could maximize availability while the vehicle is parked (likely for several days). Since that covers just about every phone, the next most important thing is to figure out how to make it interface with the outside world without the outside world needing to provide any additional power to enable that communication (i.e. I can turn on a transistor, but I can't have something like the daisy bluetooth GPIO devices running as that will use car battery power).

So, I guess I'm asking how people usually interface with the outside world using a hard-wired connection, and what devices to look for (or how to identify those devices) which make that relatively easy. Can someone get me pointed in the right direction? I'm currently just wandering the web trying to find a starting point, and since the odds are good that this forum is going to be a stop somwehere along the path anyway, I figured this'd be a good start.
[Hardware Hacking General] qubas:
What other things? And what do you mean by proximity detection? You want it to unlock your car automatically, as soon as your phone is in range or is it ok if you have to run an app and press "unlock my car" button?
[Hardware Hacking General] dannysauer:
I mean "poll bluetooth and unlock when I'm near". If I have to push a button, I may as well use a regular keyless entry fob. :)

While the car's running, I'd like to be able to run some standard apps, like an mp3 player, Wigle wifi scanner (presuming I find something w/wifi and gps) , and similar standard car pc stuff. That's all easy, though. And the programming to poll bluetooth is not that hard (I'd probably just use llama to start with). The hard part for me is really just how to hard wire a relay or transistor, and get a program to turn it on or off.
[Hardware Hacking General] qubas:
In that case you should think about IOIO (google "IOIO for Android"), it gives you a lot of digital I/O and analog input pins.

1) ASAP Utilities is a free Excel add-in that allows you to automate many frequently used tasks in Excel (examples: automatically converting cells to all uppercase, lowercase, or sentence case; trimming spaces or removing any other character you choose from the cells, remove all hyperlinks, merge multiple files into a single file, highlight every other row, etc.). Download it from http://www.asap-utilities.com and install on your computer.

2) Under the new "ASAP Utilities" menu, choose "information" --> "list filenames in folder". Select the folder that includes your files. This will generate a new worksheet that includes a listing of each file, with the name hyperlinked to the actual file.

3) Now with a little manipulation and using VLOOKUP or MATCH, you can simply create a function that will look for the cell value in the worksheet that ASAP created, and if the value exists, show the filename with the hyperlink on the current worksheet.

[Nexus 10 Q&A, Help & Troubleshooting] Rodeojones:
Someone with more experience correct me if I'm wrong, but shouldn't we be avoiding wiping system in TWRP prior to flashing ROMs? I believe I read a thread (probably on RootzWiki) that said wiping system messes things up as you lose the ability to flash a ROM in the "traditional" manner. I wipe cache, dalvik, then click factory reset. I leave system alone and I've never had a problem with flashing ROMs.
[XPERIA X8 Q&A, Help & Troubleshooting] senci00:
Hi! i was wondering if Xperia X8 E15i could be overclocked to 1000MHz because i heard from my brother (he had this phone and then i got it) and his not sure because its not possible anymore to do it anymore.

My brother had my xperia long time ago and he had 1000MHz then later when he gave it to me he unrooted it and make it to normal Xperia

[XPERIA X8 Q&A, Help & Troubleshooting] pilu1978:
@senci00: your brother is joking only with 1000MHz ;)

@fotak-x: no, you can set higher frequencies than 864 with a modded frequency table. I made an experiment earlier and reach 921,6MHz, but:

-the phone was really unstable

-needed really cold environment (around zero celsius)

-to reach this frequency needed to extremely decrease all other frequency (axi and ahb bus), so the phone was slower :(

@Gogeta: basically the arm core can't produce enough heat to get physical damages due the overheating (the most critical part is the soldering what need around 280C temperature to damage, hard to reach it with 1-1,3 voltage and 100-200mA) ;)
[XPERIA X8 Q&A, Help & Troubleshooting] Gogeta:
So we can overclock to higher value without any problem???

I mean it doesn't damages anything so we should increase value :confused:

[XPERIA X8 Q&A, Help & Troubleshooting] pilu1978:
Theoretically yes, you can set high frequencies with minimal risk. All arm cpu have extreme low power consumption (compared to the x86 cpus), the physical damage due the heat is minimal (but more than zero) The overclock ability of each 7x27 soc is different and depends on lot of thing (damages in the silicium structure, soldering quality between the core and the case, etc...). Some soc unstable on 700MHz, some working good on 800+ MHz. And the most x8 owner have "low quality" cpu, because under the manufacturing procedure all cpu tested, and the high quality cpus (what stable on 800-900MHz) marked and sold as 7x27T (turbo) with default 800MHz (this is normal, usually the manufacturers sold the damaged cpus with lower clock or disabled features, for example: you buy an i3 cpu into your desktop, but maybe the cpu manufactured as i5 with damaged core, and after disabling the damaged parts, sold as i3).

Hi all,

I normally live over on the Xperia Arc forum but I have been trying to root my mums Kindle.

Last time I looked it was on 10.2.4 which, as far as I have read, is rootable.

However last night I checked the version again just before I commenced rooting and it was on 10.2.5!

I cant seem to find any reference of .5 anywhere.

Even on amazons website the latest update says 10.2.4

I tried the root methods but it didnt work unfortunately...

Any ideas? Anyone else been updated to .5 and successfully rooted?

[Kindle Fire 2 Q&A, Help and Troubleshooting] fmkilo:
You could definitely restore to a rooted 10.2.4 if you had a fastboot cable...
[Kindle Fire 2 Q&A, Help and Troubleshooting] QuantumProcessor:
This works for 10.2.4

I found the solution! If you try and install superuser.apk directly by copying over to downloads and clicking on it, it works. Then simply grant ES File Explorer su permissions and click to mount the﻿ file system.

Idk why it worked, but if it doesn't, try using Root_with_Restore_by_Bin4ry_v1**8 & QemuRoot combination. When you get permission denied, make sure you run it again and press 3 to jump steps, but make sure﻿ you run step 4 or your device will remain sluggish

If﻿ that doesn't work try this: Rooted 10.2.4

Hopefully after running the tf101 file and qemu you can manually install superuser.apk from the sdcard. If﻿ it worked make sure you mount the﻿ filesystem with ES, because tthe shell wont﻿ work. Next, make sure﻿ to rename /system/etc/security/otacerts.****(zip) so that the next software update wont deroot you.
[Kindle Fire 2 Q&A, Help and Troubleshooting] Wilkinsss:
Last week my kindle fire 2 randomly update to 10.2.5 after I had rooted it with root many android, by bin4ry and qemu root.

I decided I would try the root many android method again last night to try and re-root the device and it worked perfectly, installed rootchecker, definitely had root access. Left the kindle on overnight to charge using a wall socket.

Woke up this morning and somehow my kindle is now 10.2.6.. I even renamed otacerts.zip to something else and it still managed to update itself to a version which doesn't even exist as far as I am aware.

Am I missing something here? Does anyone have any input?
[Kindle Fire 2 Q&A, Help and Troubleshooting] onemeila:
Amazon will update a select few device with the newest version before they actually release to everyone. You should REALLY thank amazon for making you one of the new guinea pigs haha. Also renaming otacerts.zip doesn't seem to work with the newer software versions. I've disabled all ota portions of silk using Rom Tollbox, I'll let you know on the next update. Though I'm using the 8.9 but should be the same
[Kindle Fire 2 Q&A, Help and Troubleshooting] Wilkinsss:
I find it hard to believe I've been a guinea pig twice in two weeks haha but I'll take your word for it. Should it be safe to try reroot using the 10.2.4 method on 10.2.6? I assume so but I'm skeptical
[Kindle Fire 2 Q&A, Help and Troubleshooting] onemeila:
I would think its ok. Do you have a backup and factory cable incase?
[Kindle Fire 2 Q&A, Help and Troubleshooting] Wilkinsss:
Factory cable is in the post on its way to me now, the root worked fine in 10.2.5 so my assumption would be the same for 10.2.6.

Edit: Since I am a risk-taker, see:foolish, I just decided to go ahead and root again with bin4ry's root. All is well and I have root again. I'd very much like it if I didn't have to go through this procedure once again, is there any way I can foolproof my system not to update, since otacerts didn't work last time?

[General Questions and Answers] irony_delerium:
Make sure it's got all of the updates installed. I have the same device - once all of the updates were installed on it, the worst I've found is that I have to wait for the system to settle (open Task Manager, wait until most of the usage is by Task Manager itself and not the system, about a minute) before the jailbreak will work, but then it works every time.

Most of the reason for failure that I've seen after startup looks to be because the kernel location that the jailbreak is tweaking isn't at the right location (which is why you need to be fully patched), though it will fail all the time if its done too soon after startup.

There are many versions of "the samsung multimedia dock", for many models of Samsung phones. You'll need to be more specific.

And no external dock is going to change the fact that the i9100 has a 5-pin MHL connection, which still will not support simultaneous HDMI out and USB.

As for the off-topic, there are adapters you can get in order to plug an S3 into an existing 5-pin MHL adapter.

As far as I'm aware, Sprint does not use SIM cards. If you happen across an international phone that Sprint sells, then it may have a SIM. However my gut would say it won't. Said international phone would have other radios in the device to access those bands abroad.

So, I picked up the samsung smart dock to play emulators, games, etc. but I'm getting some pretty bad lag.

Its not choppy, just delayed from what I see on the TV.

I've tried enabling game mode on my TV so the post processing is disabled, and I've tried just using a plain LCD monitor but the lag is still there.

Recently, I switched to the beans rom and that helped the lag a lot, but, its not quite gone.

I noticed that in this forum: http://xdaforums.com/showthread.php?t=1712902 a kernel dev was able to change the refresh rate to get rid of the lag.

Ok OP I have the official MHL adapter on it's way to my house as we speak, hopefully it gets here in the beginning of next week so I can test and confirm what the problem is.

The post you linked to describes a refresh rate issue, which is not the same as lag. What's happening for that guy is his screen output is being capped at 24 fps which is horrible for gaming/interaction.

Once I get mine hooked up and tested on my monitor I will be able to confirm exactly what the phone is outputting and from there we can see what needs to be fixed.

On CleanROM 4.0.5, it wasn't much better.

On Beans it was much better, closer to 100-200ms.

I haven't tested with my S3 yet, but I suspect there may be similar lag since the hardware is similar.
