I heard this was possible, could someone elaborate on how this is done? Thank you
Do *not* attempt to flash ROMs across devices. Each ROM contains a customized set of drivers and configuration settings specific to your phone. Even if what you suggest is possible (it shouldn't be, but sometimes the safeguards aren't as strict as they should be) and you'll wind up with a phone where the hardware buttons don't work, or the touchscreen is off, or the battery doesn't charge correctly, or... yeah, just don't. Unless the hardware really is the next best thing to identical (and I mean the actual, internal chips and such, not the look of the device's chassis) it is pretty much guaranteed to cause more problems than it will solve.

You know what bugs me already for years is the following...
Mobile phones, which I paid a lot for, come with poor vendor roms, which are locked. They are mostly rich in bugs and therefore poor in bugfixes, support and updates.
xda-developers mod roms, cyanogenmod, android root and so on are such great projects...
The problem with those is, that
- warranty gets lost
- not available for all phones (there are for example no mod roms for Motorola Flipout, because the bootloader has been successfully protected my Motorola and no one could hack it yet)
- the developers have to waste time with working around the protections to mod the device
It is ridiculous, you paid the full price for the phone, but never get the right to fully use it's potential.
Let's compare it with buying a normal laptop. It's also a piece of hardware and mostly there is Windows preinstalled with a loads of bloated unwanted software. This might be ok for a lot of people. And the rest? They are free to install ANY operating system they wish.
On normal laptops there are not risks when messing around with new operating systems. Of course you need some knowledge and you may lose your data, if you do not know what you are doing. But since all my messing with operating systems for PC, I never damaged the hardware, simply it is designed in a way, not to be damaged by software, it's robust.
Mobile phone vendors claim, they lock us out, because we could potentially harm the hardware. Isn't it their task, just to develop robust hardware and allow us to install any software we want?
This petition would aim for:
- open bootloader by default
- root by default
- warranty for the hardware, no matter which software you used
- free to install custom roms
- robust hardware
I'd like to start a petition and perhaps some public awareness for this issue.
So, if you want to help with anything.... Like writing a petition, a more handy text then this, for example, would be needed.
Discuss.
Installing another O/S on your laptop is not likely to break it, if it does you fix it or take it to a computer shop. A computers warenty normally only covers the junk it came with. There is already a problem with self entitled gits who dont read properly, or make an effort to understand what they are doing who download a WP7 rom, try to put it on a sensation, and expect someone to come running with a new phone. I don't believe they should try to stop people from modifying their devices in any way they want to, but they shouldnt have to cover your fumbling around either. Any modification is rightly done at your own risk.

I agree with this.
One of the major issues with phone ROMs is that you do have the potential to completely brick your phone if you don't know what you're doing. Unrelated hardware failures (i.e. USB port loses power while flashing a new bootloader) may hard brick your phone to a state of complete uselessness.
Having super user access and root on a phone is another issue that the vast majority of end users do not want to have to deal with. UAC is enabled by default on Windows Vista and 7 because it provides robust protection for people who DO NOT know what they are doing. For day to day usage of a computer, users do not need an account with any special access privilege. Even if you do know what you're doing, its still SAFER to be on a non-admin account for day to day computer use.

There are also computers which come without any software, just hardware. If anything goes wrong, like defect harddrive, then it will be replaced, because of warranty.
Mobile phones are very similar to computers nowadays. But there are no decent mobile phones without operating systems available. This is also what I vote vor.

Well, messing with software -> no more software suppprt -> but hardware warranty still ok.

I agree that this problem does exist right now...
But only because the hardware is not robust.
As far I know, (a while ago I informed myself about a few devices) it is not possible to brick Nokia S60 v3 devices. This is because the routine to flash the device is read only and can not be changed. No matter if you lose power during flashing or usb cable loss... You can always flash again. There is NO way to brick the device while flashing.
Apart from the flash routine which is hardly built into the phone, the rest of the phones software can be updated.
That demonstrates that there are no technical limitations to deploy robust hardware.

I also agree that it is saves not to use admin account for everyday use and that it's also a good idea not to have it enabled by default.
On computers you still have the option to legally use your root account. At the other hand with mobile phones this is completely unwanted and you need some kind of hack to do it. This is the difference. And this is what I complain about.
Yeah
I think just like apps there are some absolutely amazing ROMs that run better than the vendor ROMs. I think they should allow those changes to occur whether through a "vendor verified" developer or some kind of authorized ROM download channel through the manufacturer so you can get the style and type you want the most which typically runs much smoother without voiding the warranty. Great idea!
Lmao. Hell no. Carriers and manufacturers will try to start sellings roms like theyre crack. Ringtones anybody? Cmon. Only $3.
Anyways. I think the op doesnt know what hes asking for. What you want is a blank phone and you want the manufacturer to cover hardware no matter what is done with phone. Fair enough. I guess you want them to cover the phone if you burn through all your write cycles in the flash memory used because you have to flash anything you can your digital hands on. You do realize this will cause the price of parts to go up in the long run? And prices upfront will be more because they will calculate losses due to all the warranty claims. Should i keep wondering why insurance prices keep going up? Phones are built much, much different from computers. Pc's are generally modular and a single piece if defective is claimed to oem of that part. Not necessarily hp or dell. Phones usually only have one or two boards in them with all your components. So if you somehow manage to fry your wifi because you thought could improve reception or your bandwidth or whatever with something custom and it doesnt work, that whole board, system or maybe even phone depending on how its built now needs to be replaced.
I dont want to say it, but itis fair for them to not cover your phone if you went above and beyond. True, because we have become digital crackheads we usually become beta testers for their hw/sw but we also have the power of the coin too. You cant fault them if you wanted to improve their bugs/sw. You cant go banging on your drug dealers door either when he sells you some bunk cocaine and you go mix it with drano, just hoping for something and it backfires on you.
I voided my warranty.
Some interesting opinions. If this was made legal there would likely be restrictions placed on what can be changed, and it would likely end up regulated in some way.
The result would be third-party 'illegal' roms and commercially available 'legal' ones.
People like us would likely still be flashing illegal roms with modified clock-speeds etc ; )
Anyone think that they could replace a obd2 ecm/ecu with an android phone?

I may be wrong, but:
https://play.google.com/store/apps/details?id=org.prowl.torque
ive seen these, they just read parameters from the computer via the obd diagnostic port, what i meant was actually removing the the obd computer and using an android device to receive the incoming sensor data and use the data such as rpm, throttle position, and so forth to advance or retard timing tables and fuel tables to actually run the engine i have tuning software for my honda that i can run and retune my engine with but only from my laptop id like to be able to do this with an android device.
[A] 😉 let me know
That's an interesting question and not what I thought it was when I first read your initil post. Reading it literally you're asking about replacing the actual 'brain' that conductor that co-ordinates the entire ignition,fueling,emmisions and other secondary parameters that make the engine run in a harmonious symphony(oh, whatever happened to self metering by atmospheric pressure drop and contact breakers lol). I read it as taking out the OE ecu/ecm/powertrain module or whatever other term you use for it and replacing it with an android device. An interesting exercise but hardly worth the mountain range of problems involved considering you can go out and buy a custom fully programmable ECU anyway.
That is how it sounds though when you say replacing the ecu with an android device. i.e removing the ecu and putting in one running android or a piggyback ecu running amdroid....... i know, i'm being maybe a little too pedantic but it drew me in and made me read the thread and am definitely interested in finding out if there are any android apps that can reprogram or flash an ecu similar to the ones that run on windows.
I've mentioned in another thread I have a deep knowledge and experience in the car side of the equation but my knowledge of computers themselves ranks about 'interested in knowinf more but basically capable of using one n that's it' level. Or tge same as 99.99% of car drivers. They can drive but beyond that all they really know is where to out the petrol in although 100,000s of them will say they know all about cars lol.
In other words, I see know reason why technically there are no equivalent android apps/devices that can do what software packages running windows you use on a laptop. I'm in a similar but different position than you. I really want that ability to remap/flash new firmware onto ecu's except right now I don't have a laptop or desktop of any kind right now. All my online and computer needs are admirably dealt with on my Note 3 so i haven't bothered replacing either my pc or laptop when they passed on.
Was on ebay recently and seen very interesting and potentially useful software claiming to be able communicate fully with any obd1 and 2 ecus allowing you to reset, remap and 'chip' any ecus and also fully set up a new replacement custom reprogrammable ecu too although i am skeptical you could buy one that fully capable for £20 off ebay but they promise full customer support and the ability to download an entire remap for almost any make amd model so perhaps their claims are based on the abilitynof their product rather than merely sales rhetoric.
Anyway, what I mean is I see no reason why if windows can fully communicate with obd2 and android can also read current and pending dtcs, display freeze frame, live data and allow you, if you know the particular formula, to view data with custom PIDs then it seems possible that a software package written for android couldn't be capable of doing wnat these windows/mac programmes can do. I'm sure I've seen linux compatible software for desktops out there so surely an android version is poasible. BUT as i explained my knowledge of computer systems/languages is risible so there may well be a glaringly obvious reason that android is unsuitable (there's probably 1000s of 10 year olds laughing lije mad thinking is this guy stupid or what lol).
BUT if you ever come accross such an software package that runs on android let me know because if not it looks like I'm going to have to go buy this 20 odd quid ebay software AND a bloody laptop on top to bw able to use it
Hi everyone,
disappointed with altitude readings in GPS tracking software on my SGS2 I9100, I got an idea to implant a pressure sensor into it. Not that I can't live without it, it's more like a hacking exercise for fun. Anyways, let me explain the idea.
Few newer devices have pressure sensor built in. I.e. SGS3 uses LPS331AP from ST (mentioned in kernel sources and on some websites). It's well documented and is available to buy. Hooking it up (space challenges aside) would be pretty straightforward. I am certain i can find supply and SDA/SCL lines to connect to. However, I cannot hook up interrupt to main processor, and there is probably nothing to be done about it. OK, let's imagine I succeed in soldering, don't screw up the whole mainboard, and have a sensor attached.
Now, I'd need a custom ROM, or at least kernel aware of my new sensor. If all the wiring would be standard (including interrupt), I could just copy relevant parts from sources for SGS3, compile it, and expect it to work. Or something along the lines.
So, here is a question: can I communicate to pressure sensor without interrupt connected? Sensor itself supports it, but does android? With reasonable amount of hacking, of course.
I did quick search in kernel sources for SGS3, and I see it expects an interrupt input from lps331 during some init routines. However, I cannot figure out yet whether it always needs it, or can it live without somehow. I will go on reading sources. In particular, I'll look how exactly does HAL interacts with the sensor.
In the meantime, maybe someone more knowledgeable has some advice? I have very vague idea about linux kernel working, and never before looked into one for smartphone. I can read the sources, but my programming experience is limited. So, any tips are appreciated. Especially if you think it's hopeless
Hey,
It occurs to me this might be the sort of thing that might exist buried deep in some developers tool kit.
I am often stuck wanting to know more about what exactly my phone is doing. An external device which could take reported data on what exactly different components of the software system - including the operating system of course, were doing, would be very useful.
Exactly what data they were transferring and where and when, in particular. The capacity to frankly break various parts by disconnecting them - task killer, basically, but one that that does not run on the phone under inspection itsself.
There is also the need for something similar for wifi, of course. Something which gives much more detailed information than signal strength... I have never been able to find that.
This seems particularly pressing from the standpoint of owning one's own phone, owning in the sense of frankly controlling it (which is what real ownership implies.) So not just having it rooted, but being able to see into the internal workings to determine what it is doing. The degree of technical knowledge to do things goes down greatly when you can really see in there.
It would help greatly reduce the impact spyware and malware, including frankly cyber weapons used by the authorities against their own people, giving a sort of very general and innate resistance. Something which sys admins, I hear, generally quite appreciate and make good use of. One, because the user can reliably and with fine detail monitor the behavior of the phone in various ways, and manipulate it. Secondly, and perhaps less importantly, no software running on the actual phone can ever really be that reliable in the face of being duped by talented malware engineers.
Hello there, I have a very general question regarding android phones:
How can it be so hard to run an os on a phone when it is so easy (at least way easier) to run a os on a pc.
I mean even slight misshapes can ruin your phone and there is no way for a phone to boot from anything except it's internal memory. In addition to that, it takes forever to push updates to different phones which even use the same CPUs (mostly Snapdragon 8xx). I really do not get this. I have a piece of hardware in my hand which basically seems to me like a computer with a smaller screen and somewhat different Io devices, but shouldn't it be able to have all the features a full pc has? What is the fundamental point I am missing here? Is there any reason besides companies wanting people locked out of their devices, so they can keep making money? Why don't I get a message of "no is media" when I mess up with a lineage install but instead could turn my phone into a piece of garbage?
