Smartphone hacking without risk – plus, broken phones needed

http://hackaday.com/2011/09/06/smartphone-hacking-without-risk-plus-broken-phones-needed/
Scrolled into this article today. Thought some here might find some benefit to this community.

this has been covered on the front page a couple of times already, and it's only for phones with cortex A8 processors. the droid 3 users a TI omap processor so it wont wont

The D3 has a TI OMAP4 SoC which includes a dual core ARM Cortex A9 processor.
Think of these SoCs (OMAP, Tegra, Snapdraggon, etc) as an entire computer (motherboard, CPU, graphics card, etc) on a single chip.
But yeah, this guy is working with the A8, while the D3 and all current generation phones use A9 based CPUs. Maybe it will apply though, idk.

sorry, what i should have said was it requires a samsung hummingbird
this is a hardware mod, and the devs posted a list of all the phones its applicable to here:

change cpu ?

with the new exynos and mtk octa core in the market , i was wandering if its possible for our phone to change cpu ? would a octa core be compatible ?

That is not PC dude. Anyway it would be great if possible

I don't think so. The motherboard may be not compitable with new cpu

Ahh no sorry, there are two challenges that you would have too overcome, the first being the hardware aspect. The tegra 3 SoC isn't just a CPU but APU that has both a CPU and GPU on the same chip. This chip is physically soldered to the motherboard. While its not inconceivable that a very skilled person might be able to remove the chip and replace it with an identical chip (in theory).
You cant replace the tegra chip with another for both hardware and software incompatibilites, our phones whole motherboard is designed around the tegra3 and its very intricate details of operation. But let's pretend the hardware will be compatible and a exynos octa core is what we will use, the next problem is software. The kernel is the core of an operating system, on the arm platform the Linux kernel is different to that of x86 based devices, arm devices need extremely specific kernel support, you would in essence have to rewrite or re engineer an entire devices specific hardware support in the kernel, for scale the difference between mainline 3.1 and the 3.1 android kernel in our device is about a million lines of code, I'd guess lge's changes would be around 50,000 lines of code for our device.
But I somehow don't think its worth it

Why? You would lose access to THD games

right the whole kernel must change. too much for me

[Question] Moto G 2014 Processor Model

So, i got curious and downloaded the "CPU z" application to have a look at my phones specs in detail. I found that my processor was the "4x ARM Cortex A7 @1.19Ghz". however the advertised processor is the "1.20GHz Qualcomm Snapdragon 400" now, is this just a pre-manufacturing model name and I'm just being stupid or is something fishy going on here?
Also i find it odd that the actual processor in my device is clocked at 1.19 when i in fact was under the idea that it's a 1.20 clock speed. I'm sure it wouldn't make that much difference but still seem odd?
could someone put my mind at rest and tell me that I'm just being an amateur and to go back into my android noobie cave or can someone confirm that in fact something fishy is going down.
thanks!

And don't worry about the clock speed.
I hope this answers your question.

Unleashing The Snapdragon 820

Hey guys, i'm looking for a new phone, and i'm considering the 3/32 version of the mi5...the only thing i don't like is the Snapdragon 820 clocked at 1.8 instead of 2.15...and still have to figure out if the Adreno 530 is underclocked too...is there any possibility to unleash the full potential of this SoC?

wondering the same thing

It isn't possible now because Xiaomi hasn't released the Kernel sources yet. With kernel sources you can overclock it in theory but the base model Sd820 isn't the same as the one in the pro or prime mi5. It may not run stably on higher clocks.

Assuming you trust Mi5Devs, then this table shall say the difference:

So considering that table the only difference is the clock, since board codes are the same...anyway as long as i've read, there is very little chance that xiaomi is going to release the kernel sources before than Q1/Q2 of next year...am i right?

Assuming the 6-month-source-code-release-after-device-release cycle is consistent, then Mi5 source code might be released next month. So far, their Qualcomm devices always have source code released. Let's just hope for the best.

So, is it possible now?

32gb ver is underclocked and poor performance, thus not recommended to increase cpu speed

Why there is much better support in roms for Snapdragon than Mediatek smartphones?

I was wondering why there is much better support for Qualcomm Snapdragon version of Leeco smarphones than the one with Mediatek MTK?
For example check out the LineageOS (download.lineageos.org) or pixel or any other line of android's, all of them are developed for Snapdragon version. All recent versions of Android Oreo or Pie are developed and supporting Snapdragon SoC.
Can someone explain me what is the reason for such weak support in recent android versions for the case of Leeco (for example Leeco S3 X626) with MTK cpu?
Edited:
Seems like I find partially the answer in: https://www.xda-developers.com/mediatek-source-code-release-no-plans
However, I thought that android source kernel is open source so it can be compile by anyone for any SoC, I mean new source kernels has already implemented new CPUs right? Or am I wrong?
