I was thinking that dual booting on a single device would be a really great thing. A huge step.
Why we cannot do it?
Cannot we "emulate" partitions of the internal memory on the sdcard and then create a modified spl to boot from sdcard?
I was thinking that it is possible to make the sdcard working like internal memory..
Is it so difficult?

I think this would be a good idea too. have a stable boot partition, then on the second boot have our "testing" partition.
Is this even possible?
Whether or not this is possible, I don't know.
But kinda related, I would like to see a bootloader that made an "image" of the entire phone to sdcard AND would also restore the entire "image" of the phone.
Why?
It would give us an easy way to test out different roms!
You could have your stable build for regular day-to-day use, you could also "image" any other rom you install, then you could switch back and forth without the need for a computer to restore using Fastboot. Using this method, you could "image" any number of builds you wouldn't to try.
There may be a way this could be done right now, I don't know. I haven't found out how. If it's already an option, someone please point me in the right direction!
It would be very difficult cause you would have to find another OS that isn't linux based. Even with a bootloader all the files will be knocked off from the previous flash because everything in these builds are pretty much in the root folder. The OS runs on these references and if you change them the OS will not run. You would have to rework the whole OS to get this to work
Someone delete me
argh xda is so slow

Booting off the sdcard could be possible but would be pointless to do.
Everytime you mount the sdcard to the computer it would crash the phone. Also, There's not really enough internal space to dual boot. 1 decent ROM barely fits on as it is.

Cyanogen mentioned he was looking into this to try implement it into his recovery image. I don't think anyone's been able to restore a complete nandroid backup outside of fastboot...yet. However people are working on it. I think it's doable.

Maybe, maybe not. A second or third EXT partition on the sd card could possibly be used for a dual/tri boot enviornment. Only the FAT32 portion gets mounted when you mount through your phone. And there would be virtually no difference when mounting through ADB. Now would be a good time for those interested in persuing this notion to have a look at the data2sd thread. Sounds very possible to me.

no, i'm pretty sure all partitions get mounted, they just don't show up on windows.
on linux they all appear for me when i mount the phone.
also, sorry about the triple post, dunno wtf happened there.
Debain As Primarly OS
What Ive Been wishing for is someone to make the Dream Boot straight to Debian, No android running in the background.
Then we could boot into a debian with g1 drivers (if open source) and have gpu accl. x11.
Then maybe dual-booting android.
Im willing to try to get a debian img to boot on my g1 if someone wants to tell me where I would start to even try to attempt it.
lolz
Booting straight to Debian would be cool, except there is really no use for it on our G1's. We are best off running after loading Android, although I'm sure one day we could just boot Debian. What would the point of Debian be on our G1's? I'm running Deb5 on my Dell Mini that has a 9" inch screen and can barely see text.... how in the world would this become useful on a 3" screen???
just my £0.02
there is an old saying in my country. "if you don't believe it can work, then it won't for you". that holds so true for development. yes you will make mistakes on the way. heck i'm on my fourth G1 so far (and i suspect there will be more to come!) I love this phone, and i love the fact that we as a community can build such amazing things as the hero rom for the device.
what would we have done if the first person had said the wheel was impossible? or if the first person had said that fire was impossible. or (shock horror) electricity? or television? or telephone? or GPS? or the internet?
all of those were impossible until someone worked out how to do it.
dual boot would be pheasably posible, as the device is primeraly a computer first, and then a phone second. it boots a linux kernel from the bootloader (if i am correct in my understanding) so all we would need to do is create a bootloader with a choice in it, and then direct the phone to boot a second partition from the SD card.
the phone does mount all partitions - but only if the OS understands all partitions (test it for yourself - if you have windows and apps2sd mount the partitions and then run an app from the card it still works. but it does not under linux).
to answer the what would be the point questions, what would be the point in not doing it? surely development for a device like this is all about trying stuff, and then if it doesn't work not doing the same thing again.
i believe that a second OS would boot quite comfortably on a decent SD card. not that i have this working or anything. to make the screen readable, you just use a lower resolution (320x480). i would probably not want a full-blown GUI linux anyway, what i would want from a dual-boot OS would be a working command-line debian with FULL hardware access - allowing me to really use the phone as a fully-functioning remote terminal for my server.
i recon, though, that one thing that would be absolutely amazing is being able to have a fully-portable totally reliable XDA-Developers OS on my phone.
so, why do we not just try as much as we can to get this working? how do we start?

Just hack the spl and flash it, but be cautionous as hell
Okay, I dont claim to know alot but I'll share my thoughts anyway
When you mount the SD all partitions get mounted, if you go into disk management in windows you can see the 'Unknown' partition if you have an ext2 partition.
Secondly, we don't really 'boot' debian, it just mounts an image file on your SD card that contains the debian binaries. As I understand it there is no reason these binaries couldn't be included in android (like busybox).
Thirdly, do we really want debian? What we need is a very light OS, android is the perfect base, take away all the gloss and its linux underneath. I love the idea of having repositories and being able to apt-get and even develop on the device.
Lastly, we're forgettign why android is such a good platform, the reason android is useful is because of the Dalvik VM, it's what allows us to make portable apps that will work on any android phone. I seriously doubt everyday users will be interested enough to learn to compile source on their phone. I've worked programming games for mobiles in J2ME and it was horrible, there was barely any portability between manufacturers, i believe android will be alot better adn from what i've seen (with people porting from other droid devices) this seems to hold true. It will be interesting to see if Android gets bloated with manufacturer specific API's like J2ME.
Also I'll just throw this out there... I'm not a fan of being tied to google, yes google helped along the way, but its not 'google android', its android. Wasn't it strange hoe Gmail worked fine, but the email app didnt? (K9 is perfect though!)
hi guys, i'm not at all a developer of any kind, i suck even at web design, but here's my thoughts expanding on the whole "what if the wheel didn't work" scenario
inventions are created by the need to do something, we need to get from A to B faster, lets make a car. we want to entertain our families in the evening, Hey look, TV. i need to tel my wife to get some milk while she's at the shop, Voila, Mobile Phone.
Basicaly the point i'm trying to make is, if somebody finds a NEED for dual boot on android, then so be it, it shall be done, maybe not today, maybe not tomorrow, but if something is needed, then something shall come from it. we develop technology when we need to do something faster, easier, or just plain do it.
if somebody decides they NEED dual boot, i'm pretty sure they will figure out how to do it, either that or ask haykuro for some tips and alot of help, but i think he's still too busy with regular life at the minute, i'm not so sure, all i know is he's definately a legend, and maybe will want a piece of dual-boot pie
So who is the great man who want to try to do this? ;D
I offer my help, if it could be useful..
re: dual booting
would it be blasphemous to want to try out winmo 6.5 or 7 on these?
personally, i'd love to see WM on here. mainly, just so we know it's possible.
People are always slating Windows but, personally, i don't see whats wrong with it (Linux is my primary OS and always will be ). It would be nice to have say WM for work and Android for play
any news on this? I would really like to run a hero rom one day and then cupcake the next while not losing my settings...
Hello,
I've purchased the Yarvik TAB450 2 weeks ago, used (6 weeks old) and I now know why the seller sold it.
It's slow, it's not efficiently installed (5.6 GB free, but I'm unable to install apps), move to sd of apps breaks them, Android is outdated (2.3.3) and not all apps run on it. (at least firefox and age of wind crash)
Lots of reasons to ditch it again, but one to keep it. I haven't found a custom rom for it and I'm curious if I can build one for the tab. (as the specs show more then enough promise and I haven't build anything for a while)
I would like to build an environment which I can use for something else then a glorified ebook reader. However I haven't found any manuals for a general rom build. How to proceed?
I would guess the following steps are needed:
Install sdk (done)
Install other stuff (what?)
Get source (have to locate it)
Determine hardware used in tab. (how?)
Build rom
Test in emulator (is there one?)
Install on tab
Have fun
This is very general, I know, but details will be added later. (when I have them )
The questions I hope to have found the answer of soon are:
How to setup a build environment in Debian
How to determine the hardware in the tab
How to safe the current rom (it's rubbish, but at least it'll let you read ebooks )
Is it possible to boot an image from the sd (of USB stick) to test it
The last 2 points are to prevent destroying the tab while testing, as the manufacturer doesn't have an image, 'as it's in rom'. (which is altered when trying to root it, as I've discovered lately)
I haven't got a clue what I'm getting into, but I hope to get a useful tab out of it. (or the tab dies trying ) I hope to prevent the latter, but when that's not possible, it'll be sacrificed to science.
Whoopsm crash...
The 450 crashed thursday. Not the software, but the device fell. The screen is broken, so it's not responding to touch. I'll see what I can do with the command line interface, it'll gonna be entertaining, but I guess someone else has to take up the challenge for a complete rom. (as I can't test the correct response of the device)
It's dead Jim...
I am wondering if anyone knows of any way or if someone is working on a way to get ICS or JB to boot on a home-built PC? My PC is AMD 64, 8G RAM, etc. I have seen some instructions online, but they failed to mention that you must have a certain laptop or tablet. I would like to be able to tri-boot Android and run it whenever I feel like (probably use it the most). Thank you for any input.
Massive overkill. Why not simply run VMware and stick Android in a virtual machine?
android-x86
There is a project called "android-x86" - this might help you.
I tried android-x86. That is where I found out after several failures that you can only use a handful of specific Lenovo devices to boot into Android. Apparently there is a way to use Android 1.6, but who wants that.
As far as the overkill thing. Well I did build it as a workhorse PC. And I could run VM. But I would rather boot into it. I think it would be great for average tasks.
How difficult would it be to make it work for myself from AOSP?
Kernel build, hardware support etc. That's why I just run a VM for mime when I want to play. Also means I can access all my synched days such as SMS messages easily on my PC.

Hello,
I do hope my questions fit in here.
I recently bought the LC-Power MIRA-1 10.1" tablet. In google play it is called "unknown M105F"
the tablet has a 1,2 GHz A10 - ARM Cortex A8 CPU and a Mali 400MP GPU
i do have some experience with backup/root/uc&oc and even custom mods with my motorola defy phone (currently running cm7.2 stable)
when "playing" around with my defy i found it was sold in big numbers and is very well supported not only here but in any number of other communities. however, since my new tablet is pretty new to the market and no brand tablet, finding information on it is near impossible.
i do hope this will change in the future, especially since I really feel that my tablet is well suited for a number of tasks and with the price tag of ~150 EUR might even have a chance of finding its way in the hands of many people
anyway, even if the tablet is fine as it is now, it could be better. i am talking about modifications and this is what this thread is about.
1) BACKUP
in case i screw up, I really would love to have the possibility of resetting everything(!) back to factory defaults.
with my defy it is as easy as downloading the official sfb and flashing it with rsd lite
this wont work here for obvious reasons
is there a possibility to download the firmware to the pc (from the tablet) and later restoring it? probably not
so the only way left is nandroid backup?
easier said than done with a new device and without root...
also, i would very much prefer to have a backup without root / be sure to be able to remove all modifications i made like installing clockwork mod and rooting...
2) ROOT
for various reasons I'd like to have root. according to my information, rooting 4.0.4 is dependant on the device.
considering i have an unknown device, short of trying every possibility, what else could i do/try?
3) UNDERCLOCK/OVERCLOCK
I would LOVE to try to UC and OC the tablet. I know this might fail miserabely, but I could try.
IF i had root and any idea on how to find (again, short of trying every possible app) a working app.
any ideas?
4) GENERAL CUSTOMISATION
i learned that a well made custommod (like 7.2 for my defy) can make a huge difference in customisation and performance.
I would be willing to try a stable custommod but for now, I dont think that is viable since they usually are device specific.
So all I can do is use another launcher and hope for the best. I really like the performance, functions and especial the ability to customize the AWD Launcher that came with the cm7.2 for my phone.
According to google play the awd launcher is not compatible with my device. i cant imagine why, but there it is.
now, is there a way to still try it?
and what launcher comes closest to the performance, feel and customizability of the awd launcher (i do NOT care about special visual effects on which most launchers seem to concentrate)?
5) SIMILAR DEVICES
the best way to approach all those questions might be to find a (very) similar tablet and try to extrapolate answers from there onto my device.
however, I have no clue on how to figure out what chipset my tablet uses and what other information might be needed to try it that way
---
thats it for now
any and all help will be appreciated!
thank you for reading this

Hello
okay, I have some news...
since no one had anything to say I went ahead and started trying stuff out...
Apparently, the tablet is rooted by default (or my measurement of being rooted is wrong):
- when i run the app root checker, it says it is rooted
- when i run adb shell / su the prompt is root:directoy #
- i can create and delete files from /system/app
still, something is up...:
- using the adb shell i can create a file in /system/app (touch test.tst)
- if i try to delete/move anything in the adb shell from /system/app apparently the file can not be found
- it works in terminal emulator
- ive installed superuser, but have yet to see the "application asks for superuser rights"
- with the default file browser or es file explorer i can not get to / (stuck in /sdcard) EDIT: Resolved, layer8 problem!
ive also tried some overclocking apps
- they either do not go beyond 1.2ghz (stock) - the apps however is more or less to uc, not oc
- they crash the tablet even with 1248mhz - maybe the scaling gouvanours fault?
- underclocking seems to work (by accident i set the mhz from 1200 to 60 and well... it was SLOW)
i also found out some stuff (quick info system pro)
- ARMv7 processor rev 2(v71) (ARM Cortex A8 1,2GHz - at least according to the tech sheet at the manufactorer)
- sun4i
so, i wonder:
- is the tablet actually sold rooted? then why do i not get superuser permission popups?
- is my hardware not overclockable with (those) apps (i have) and/or do i actually need a custom kernel (ive read abput self compiled kernel for sun4i and another tablet)
ive gotta say, even with a bit of experience in android (acutally, very little) and a bit of linux (not too much, but decent enough) i am sorta confused
...not alone
I´d bought 2 devices LC Power Mira 2 yesterday...they should be delivered on friday...so hang on...you´re no longer alone...
It could be that the device is rooted...as far as I know...
Google runs some kind of an quality assurance by denying some "nobrand" manufactures the total Android 4.0 compatibility.
For an example the Arnova (Archon´s budget line) 10b G3 is running 4.0 but without the Play Store, ´cause the device is not fully supported as an "Quality Android 4.0 Device" and you have to use a custom rom on that tablet.
That´s one reason to spend 5 Euros more for the Mira2 which have it all onboard...or am I wrong...?

Yes, indeed, at least the MIRA-1 tablet does come prerooted. This is of course nice (since I do not have to try root it myself) but also troubeling, since there is a good reason that android devices usually are not sold rooted. The bigger problem however seems to be that the superuser app is not working properly, i.e. I do not get the "this app is requesting superuser acess" question and probably for the same reason can not get my file browser (ES file browser) to go into the / directory.
what and if other apps could have trouble with the root access that apperently not every app is "finding" i dont know. i do hope not!
however, using the android sdk or shell emulator, all kinds of SU operations can indeed be executed.
concerning your google play store question (was it a question?), yes, the MIRA-1 tablet has google play installed and it can be used without any peticular limitation. its a safe bet that the mira-2 will be able to, too.
my experience with overclocking the tablet does not bode well. even a 48Mhz (smallest step) increase will freeze it. I have tried multiple apps.
i do not have any absolute answer so far. it could be that the oc apps have trouble with the root or are plain the wrong apps or simply that the cpu is already at its absolute limit and just can not be oced.
further investigation into this issue has revealed that apparently other tablets with similar hardware configuration may be able to overclock but apparently it would be neccesary to edit config files and with those compile the kernel. this is far beyond of what i can do and would be willing to do.
i am a bit sad about that, then yeah, the tablet is nice and good enough for me and worth the money, but a bit more speed could not hurt. it does happen that the tablet gets unresponsive for .5-1sec when browsing the web.
one last thought. the gpu does seem to be pretty "powerfull" (please, do not take me to literal.)
but i have yet to find any game that does not run smooth and looks good. according to my information i came across, the gpu is indeed well known for its good performance in 3d and full hd playback
(one exception. snes emulator is unplayable slow. but here i too blame the cpu, not gpu)
...
...sounds good to the fact that I won´t expecting more for this price. Hey 157€ is´nt very much for an 10.1" tablet...
...I´d got also my LG P990 as Android device and smartphone...believe Me...I know what it means being betrayed...no updates...Tegra ? - nVidia ?...I don´t wanna talk about it...lol
It´s rooted and I never got problems with some apps about this fact...ok it´s still on 2.3...thanks LG, by pretending the update comes in May 2012...
I´d send an e-mail to the support of LCpower, by asking about an list of compatible 3g Sticks...10min. later...Answer and an Exel-file with the whole list...great service...´til now...
I just hope that I´d bought 2 "nice" family tablets for a few funny games, sometimes a movie, some social networking...nothing more.
Hope I did´nt misunderstood something here...
...is it only possible with another Explorer (like Astro and ES) to get to the files of an external SD Card or not ???

well, the external sd card behaves a bit strange (at least for my understanding of android)
in short:
we have 2+1 memories in the tablet:
1 internal memory (small, i think 256mb, quite full with the android os and the apps)
1 other internal memory (the 8GB)
1 slot for the sd card, the +1 memory
now, everything begins at / (i figure this is the small internal memory)
the 2nd internal memory with 8gb is mounted under /mnt/sdcard and i believe /sdcard (where i would expect the sdcard!)
the sdcard itself can be found at /mnt/extsd
es file explorer has some trouble with that. if you launch it, it will start in /sdcard
since it does not recognize root, you can not go to /
since you cant type in the path by hand you can not go to /mnt
so apparently you cant browse the sd card with es file explorer (or i havent figured it out yet)
the preinstalled file explorer has no trouble with it at all. in fact, it even actually sends you to the right memory when you tap the corresponding symbols (as preinstalled file explorers go, it is actually not so bad)
ive tried setting up some symlinks but failed. maybe i did it wrong, maybe it just wont work.
another possibility to fix it could be editing fstab. but this could be dangerous and/or cause more problems then it helps
i filed that as a minor inconvenience to be adressed when im bored enough
...
Ok...this means...that I just hope that the Mira2 is accepting my microSD16GB and I can use it quite as normal...
In 2.3 it´s still the structure: " /mnt ---> /mnt/sdcard ---> /mnt/sdcard/_ExternalSD"
Is this structure changed in 4.0 ?

well on my mobile phone (motorola defy with cm7.2) i have /sdcard and /mnt/sdcard - actually being the sdcard
i also have /sd-ext which is empty
i dont know if that is the default for all android versions and/or if there are differences in sd-card mount points in android
however, the behaviour of the phone seems more logical (or its just that i am used to it)
whatever it is... the sd card of the tablet can not be accessed by /mnt/sdcard/ANYTHING
however, further research especially with the es file browser has shown that indeed you can browse the sd-card /mnt/extsd by switching the two in the favorites options.
so, maybe it makes sense, maybe it dont.
maybe its andorid 4.0.4 conform, or not.
what is important is that apps apparently dont mind (they do get installed on the 8gb internal memory mounted at /mnt/sdcard and /sdcard) and so far have yet to refuse to work/show strange behaviour
also, it is possible to move/copy etc files between /mnt/sdcard and /mnt/extsd and browse both directories, at least with the default android file explorer as well as es file browser.
So...a little update...the 2 devices are now in our hands...for about one week...
....and everything I can telling 'bout them...
,,.they're working great. Not a single bad issue, no freezes, and as far as we can see...
...for a price around 160€ there is no better tablet on the market.
Since yesterday I run the game Wild Blood (Unreal Engine 3 Game) which is most famous for an app who killed some tablets and phones...but nit the mira2 ...it's playable.
The device was also rooted "out of the box" but I can't find a single problem with the external SDcard or other USB Hosts I tested.

Had the same issue thanks for the help guys
hello, I wonder if there is any program that can create a register or log(HijackThis it´s a pc program)of all the programs and applications that are in the phone, and I want to know what can be uninstalled and deleted because the service provider install applications that I've never really used and all they do is eat memory and slow the phone.
well I hope this time not confuse the forum channel, pls any help would be helpful to be able to enter the modifying phone.
PD: my phone its a Samsung Galaxy s4 GT-I9500 / 16GB +64GB sd / Android 4.2.2 / No ROOT.
It's definitely necessary as our phone process no less harm if under malware attack than our PC. I'm all ears as I was a big fan of HijackThis during the WindowXP period. I'm sure phone with an Operating System would surely have a similar way to detect malwares on our phone. :fingers-crossed:
