Reboot

Hi,
I am new to tablets so maybe I am shooting in the complete darkness...
Why isn't it possible to reboot TF700?
Even with root (Tasker) the reboot action is disabled.
Is that related to kernel or something else?
Is it achievable without new custom ROM?
Thanks!

If you are rooted you can. In that case, you can try RebootMenu from the Play Store (and in there are several more options to choose from as there are more apps that perform this particular trick).
EDIT: just search for "reboor widget" in the play store, and the one you find from fadroid is prety nice as well. Used it before (as many of the others).

Hi,
thanks for the tip.
Is there a way to have a reboot options inside the menu when the power button is long pressed?
I think this is cyanogen way, but i am not sure...

Not that I've found so far -- I know what you mean, as my SGS2 does that when long-pressing the power button. This would be something a custom ROM might be able to provide.

I know on my Bionic I hate going back to stock because I miss that reboot button.

Found a great solution!
Download: Elixir2
Create: status bar widget (or home screen) with reboot toggle.
It show menu with reboot, recovery etc.
Not exactly same thing as with power button (where i also like the fact that it all looks native ICS), but still a very nice solution. :cyclops:

I can't wait to get CM10 running on this thing lol. It looked great for the early stages on the Prime.

I just open Terminal Emulator and enter the "reboot" command, but then again I sometimes have "values not saved" or sth like that from No-frills CPU (which is actually bogus, as there was nothing to save, it still has the same things to load - governor & scheduler, doesn't reset the settings or anything, so probably some precaution measures in the code)

Not quite as nice as hitting a button to do it lol. I think that turning off the device then turning back on might be faster than finding terminal emulator. I'm sure that's similar to what the actual widgets and such do.

Yeah, me too, CM10 is going to kick ass to my Infinity as soon as its available
But, I think more important right now is to unlock the bootloader - as soon as possible - we just have to wait for Asus on this one, which sucks a bit. How long did it take for Prime and other transformer line products to receive an unlocker?

TF300 got it very quickly (less than a month since original release I think)

Not sure about the Prime, but my TF300 got unlocked about a month to a month and a half after release. I think it was released at the end of April (in the US), and the unlocker was released either in the middle of May or the end of that month. It was a long wait even though it actually wasn't that much time.

Not possible. Devs have been trying to crack the Asus unlocker app for months. Asus' encryption is RSA-2,048 (that means the key is 2,048 bits long), which is almost completely unbreakable without a supercomputer to perform a ton of calculations. Even the NSA can't crack it efficiently.
For example (I researched RSA-2048 as I wrote this post), the most complex RSA encryption to be cracked thus far is RSA-768. The team that cracked it estimated that a 2.2GHz AMD Opteron with 2GB of RAM would need 1,500 YEARS to do the math required to break RSA-768 encryption.
Can you imagine how long it would take to break encryption that's almost 3 times stronger than that? Unless someone can come up with an insane algorithm to factor 2,048 bit numbers or you know a developer with a supercomputer laying around, no one's about to crack Asus' bootloader any time soon.
Edit: I should have paid more attention to the article. The team of crackers estimate that the desktop I referenced earlier would take "4,294,967,296 x 1.5 million years" to crack RSA-2,048 encryption. As terrible as a 2.2GHz Opteron is these days, I wouldn't expect much better from a top-of-the-line modern computer.

I don't think we have that much time, even with the Infinity.

No, even with a crapload of vitamins and healthy living to the max I won't make it that far (neither would I wish to). Oh, well, a month's waiting isn't that bleak when seen in this bit of context.

I don't know if this applies to the infinity but there are other ways of cracking this stuff. For my evo 3d, the boot loader unlock method involved intentionally bricking the device to access a hidden sort of mode where the partitions could be rewritten. If I remember correctly, that bootloader was also encrypted.

Failing that, if we got root we could probably try the 2nd init trick used on locked down Motorola phones, where immediately after the bootloader loads a rooted Asus firmware, the trick unloads everything but the kernel and starts loading your custom rom. The only flaw with the approach is you're still locked into using Asus's kernel, but otherwise you're free.
That said, with an official unlock I cant imagine there'd be a ton of demand or developer interest in such a solution.

[Q] A210 and MAG2GA TRIM bug, A510/700 affected, too?

Hello all,
over at android-hilfe.de is the home of the A210 Cyanogenmod port. Some time ago we discovered that the A210/211 uses the Samsung MAG2GA eMMC chip. According to EMMC Bugs this chip is affected by the TRIM bugs that plague a number of Android devices.
This would explain a number of bricked devices that users experienced with LagFix. Unfortunately not using TRIM means that the tablet slows to a crawl after some time in use.
Questions: Does the A510/A700 use the same eMMC chip? If so, did you work around the problem? How?
It seems that the 2012 Nexus 7 which uses very similar hardware is not affected thanks to a patch in the eMMC driver. Unfortunately the A210 kernel maintainer informed us, that the A210 uses a different driver, so the Nexus 7 fix is not immediately applicable.
Regards
Joerg

Thanks for the info, maybe this explains why my beautiful clean a700 is now a nice clean brick. That is if its the same chip.

I think it is. I found this post from pawtip, where he writes: "FStrim will have no effect on our device since I've disabled TRIM support within the kernel, as it is this command that causes bricks on our device. (There is a bug in Samsung's EMMC firmware.)"
I'm still curious how the 2012 Nexus 7 can safely use TRIM (it's baked into Android 4.3) and whether it is possible to adapt the fix to other devices.

According to Samsung, only secure trim is broken and normal trim can work fine. But I'm not going to risk slowly bricking a lot of tablets by enabling it.
The bug will slowly break the eMMC which leads to freeze when the problematic block is read. Wiping caused a lot of brick because the entire partition is TRIMed. E.g. If the bug is present, enabling TRIM for files may not brick it right away, but may brick it one year later.

So would it be safe to say that once the a700 (like mine) is now in apx that an nvflash if it was available would be of no use as the emmc is now physically damaged.

Not physically damaged. But yes, it's not fixable. There's a lot of posts about this, so please search if you want to know more.

But what about the original nexus 7? It uses basically the same SoC and the same eMMC. And yet there is lots of praise for the way TRIM in Android 4.3 makes it fast again. Why is this possible for the Nexus 7 but not for our Tegra 3 Acer tablets?

It's a risk issue. Google has exact information from Samsung about what works and what doesn't. They can also probably replace eMMC chips if they beak them. If I break my tablet from experimenting, I can't get it fixed without spending a lot of money.

How to make an APP NEVER close

I am playing starwars galaxy of heroes app. and it has some uses for the game to stay open. But as soon as i multi task the game gets shifted out of the processes somehow.
Is there a way to change this so i can let this app stay open untill i deem otherwise (appkiller or whatever)
I dont wish for it to restart. When i do my raid sometimes i have to wait 1 hour to post my actual damage in the app.
So that would leave my Shield K1 tablet unusable for other things, like chatting or other games in the mean time..
Hope someone knows the answer!

Anyone? surely this must be possible

The game probably takes so much resources that android has to kill the game to free up resources for the other apps you open. You need a way to trick it into using other resources or killing other processes instead.

I'm not sure you should modify anything to prevent this because you'll have to modify the native android task killer, you'll probably cause more issues than this is worth.
I suggest you deal with, it's not worth screwing your device up, it's JUST a game, it can't be that important.
Since this is most likely due to your device having limited RAM, there's probably nothing you can do that would truly be effective without interfering with vital processes that your devive requires.
The simple solution would be to play the game on a secondary device such as a phone you aren't using or a tablet. Then you can play your game on one device and do all your multitasking on the other. Or buy a device with more RAM.

For me it is that important. it is mainly why i even use this tablet. I spend hundreds of dollars on this mobile game.
It's a hacked device. this is silly. surely you can have controll of your processes which it kills or not??

Yes, it can be done, but on a device with limited hardware, you already don't have enough RAM to go around, some of your vital processes probably can't run at the same time that the game is, you can't get blood from a stone. Get it?

Well isnt this forum with knowledgable people. Ive got enough ram to run this game. often just as soon as i switch out of focus it exists because yes it may use quite some memory. but by no means im out of memory. i check this with an advanded task manager. Often I have more then half of my ram still available when the app is open.
Surely there must be a way to "lock" a process in with all the modding going around here.

As far as I'm concerned... This is the finest, well aged, click-bait... And therefore deserves none of our time...
If its patchable... It'll get patches... If it requires physical access to the device to set up (which based on wording, is my guess) it's not really a thing...

Mobile Operating System Idea

Hello,
I am here today to share my idea for a mobile operating system, perhaps a derivative of android or its entirely own thing.
The operating system would have a very simple interface. A background (of the users choosing), and in the foreground would be the users apps. The apps would be circular and settings would be simple to understand and wouldn't take up a zillion pages.
It could go 2 ways as well, 1 way being what I already stated and the other following more of a feature phone where you can't put apps on it, you only have the basics but with a touch screen device.
This operating system would be designed for absolute simplicity in every way as it is primarily targeted at old devices with limited power (or just not as much power as today's devices), it could also be placed onto new devices if there became a demand for it but it is primarily targeted for old devices.
I'd attempt to develop this myself but admittedly I have very little knowledge when it comes to code.

Just put a theme, and organize your apps

Sometimes I just wish smart phones can be like pc.. Install the os, load in drivers.. And it'll just work.
Unfortunately it doesn't. In order for the os, in this case Android to work, it needs to be able to access the hardware via drivers. It is not able to load all the required drivers used by so many phone manufacturers each having its own design. From processor to sensors, to have a generic one. But if u include all into the firmware, it will just be very slow.

Like living things, electronics have an age too. As you use it, it ages, sort of like wear and tear.
Things like heat and heavy usage makes it age faster.
The closer you are to its lifetime, the slower it gets.
Having a lighter rom will help but not by much, and will only get worse.
Best remedy, is a new phone.

Did you try LneageOS? It's fast. I think you want to support an old phone but with new features, which require fast processors and lots of services in the background. If you only want to call there are burners for that.

Usually in older phones such as note 3, when it gets sluggish a factory reset tends to fix it for a few months before getting sluggish.
If it's sluggish even after a factory reset, I'm sorry it's the hardware that aged and there is nothing you can do about it.
Is like getting an old athlete to run. Even a flagship phone or Olympics gold medal runner can't run as fast anymore.
