Guest AceOfSpades Posted January 24, 2011 Report Posted January 24, 2011 Hi, I just wondered whether this would be possible, seeing as the roms are ~100MB in space and we have (I think) ~500MB of internal memory for roms, would it be possible to partition this, and mod clockwork recovery for dual roms (select which to boot from clockwork). I imagine this would be really useful for devs as they could have a fully working rom and some more experimental stuff at the same time, it would also be great just for ROM testing etc. Apologies if this has been asked already
Guest IronDoc Posted January 24, 2011 Report Posted January 24, 2011 Not to say anything (positive or negative) about the possibility of the rest of it, but we don't have '500MB memory for ROMs'. We have 500MB of memory for everything, including data, boot and recovery.
Guest Phoenix Silver Posted January 25, 2011 Report Posted January 25, 2011 humm android is a unix system where mounts are in fact only files i think it would be possible to do this
Guest rjm2k Posted January 25, 2011 Report Posted January 25, 2011 (edited) Somebody on xda was working on this, basically by flashing on the fly if I remember correctly. http://forum.xda-developers.com/showthread...833#post9345833 Edited January 25, 2011 by rjm2k
Guest shadowninty Posted January 25, 2011 Report Posted January 25, 2011 this would cause problems with Recovery and would need a separate /Data partition

I imagine this would be really useful for devs as they could have a fully working rom and some more experimental stuff at the same time, it would also be great just for ROM testing etc. Apologies if this has been asked already i guess this would be possible you could create 2 data and 2 user partitions etc. and put a stub in choose which to boot into. not sure if this would be any use except possible for development. not sure it is much value for end users though.
Guest ololizoz Posted January 25, 2011 Report Posted January 25, 2011 When I had my last phone (Samsung i5700 Spica) they dualbooted. One OS was installed on the internal memory and the 2nd was installed on the SD. Is there a chance that a dev can port it?

Guest hecatae Posted January 25, 2011 Report Posted January 25, 2011 the msm7227 cpu is capable of booting from sd card, nothing to stop trying for windows phone 7 instead

Guest hecatae Posted January 25, 2011 Report Posted January 25, 2011 1. Closed System based on optimized win CE 2. Drivers whoops, forgot it was windows
Guest Rotmann Posted January 26, 2011 Report Posted January 26, 2011 1. Closed System based on optimized win CE 2. Drivers HD2 runs windows phone 7 pretty well. This may be due to similar hardware to WP7 HTC devices.
Guest El Nino9 Posted January 28, 2011 Report Posted January 28, 2011 HD2 runs windows phone 7 pretty well. This may be due to similar hardware to WP7 HTC devices. android devices can only run android! windows devices can run windows and android and anything else that devs can port depending on hardware. HD2 is the best "dev" phone out there in regards to what it can run and has a huge community. now with that said i will try answer the main question. KENDON has already done a dual boot for the HTC hero back in the day. yep he has a SF but stopped developing for it, but i dont want to get into that. i respect him highly so yea. if you got to their site and you can search there for the dual boot method used. you will need to partition your SD card. that said you will be dual booting two android roms. also another user has already posted it up here dual booting thread fround on XDA
Guest uncorrupted Posted January 31, 2011 Report Posted January 31, 2011 My thread on xda was linked to and it is easy to get something working on one specific phone, but trying to get this working on most phones has been a challenge. Some are able to use loop devices, some can mount ext partitions in init.rc and some can't do either. I should be releasing it in the next Satori so, as it is working on a number of phones.
Guest Hopelessness Posted February 1, 2011 Report Posted February 1, 2011 I'd quite like to be able to run Ubuntu natively on the phone...
Guest Phoenix Silver Posted February 1, 2011 Report Posted February 1, 2011 not ubuntu but perhaps tinycore ;) why not with unetbootin

LOL thats for the info about dual boot. and about the windows thing i just wanted to put it into noob terms because im tired of this question being asked so many times. we can barely run android on the blade in terms of the RIL issue, no roms except ones released/leaked for providers.

Couldn't you flash the other boot.img to recovery? Or does that not work?
Guest kendon Posted February 2, 2011 Report Posted February 2, 2011 Couldn't you flash the other boot.img to recovery? Or does that not work? might work, but tell that to a noob with a locked spl... f-up both roms and you more or less have a brick. lost interest in this, i don't really see the point in dualbooting. also at one point i stopped flashing my phone and started using it, and then you want ONE rom that works, not two that don't.

Guest uncorrupted Posted March 10, 2011 Report Posted March 10, 2011 After looking over several different scripts including kendons and working with them I finally went a different direction as each one was for a specific phone. Yes, Kendon's worked on mine with some modifications, but I started to work on getting it to work on the EVO, and then another and another. Turns out that making it work on multiple phones was a challenge as each one has different specs, kernels and mount-points. For me I like my Sense-based ROMs, however they do tend to slow some things down, including some games. Others like the look, feel and speed of an aosp rom (especially CM7). So for them to switch back to Sense or whatever UI it is they have to update or do some testing, they can easily do it with out backing up and restoring. I'm finalizing my scripts now, which are ran through recovery to set up the roms, and once you do that it's a matter of running a script in the gscript app and when it reboots you are in the other rom. You can even make a shortcut to the script on your home screen.
Guest fonix232 Posted March 17, 2011 Report Posted March 17, 2011 any update here? I see no. But I wanted to ask, are you interested in MeeGo? We should try to port it :D
Guest kendon Posted March 18, 2011 Report Posted March 18, 2011 not particularly, but i am generaly interested in all modding and porting, so...
