[Q] Multi-Booting

Hi,
It just came into my mind. Since we can have custom recovery and android recovery also boots, can we have multi boot option in Defy as like in a PC's

Good question ..............i think there is no answer for this question

some resources would have to be used by both ROMs..
with the current hacks it can't be done easily.
i guess some way of ramdisking the shared resources will have to be used.
basically, if you think about a hack for defy ask first:
can it be done in a completely open (=bootloader not locked) phone like nexus ?
if yes, ask:
is it WORKING?
if yes also, so maybe it can be done.
nevertheless, it's easy enough to create a script to backup & restore NANDROIDS.
but then every switch between roms will take like 25+ minutes, so it won't be a real multiboot.

Somebody at one point on the desire was working on something like this. Run rom from nand and other rom from sdcard.

I think there are two possibilities for this to happen: first of all, we should try NAND boot for the primary ROM, and try somehow to load the secondary ROM from the internal memory (it'll be faster than the SD Card, I think). The problem here would be allowing the bootloader to read from internal memory instead of NAND. I know this can be done based on the number of WinMo-Android and iOS-Android dual boot solutions, with a menu to choose which system to load, in the boot screen.
The second option is the method used by Wing Linux to run Android on old WinMo devices. In this method, you MUST boot in WinMo (or, in our case, in the primary ROM), then open the app that loads Android (the secondary ROM, for us). Android does NOT run emulated in this method, but, since the device can't dual boot directly, the app sends a signal for the device to restart running from the bootloader to the SD Card (for us, internal memory). This second option is, somehow, like the System Recovery app (not 2ndInit), that has an option that reboots directly into Recovery. So, if we can tell the phone to load from custom Recovery (which is, in fact, in internal memory, not in NAND), I think it's possible to make it load an entire ROM from the internal memory (without having to mount it everytime and waiting for the dalvik-cache to load).
However, it's surely a hard work to do.

Yes one from nand and one from sd card..........good......can we partition nand and use it both on the nand itself??

it should really work if we use virtual images or sdcard-partitions instead of system, data and cache partitions.
This can be changed in the init.rc-file(of 2nd-init).
The creator of the 2nd-init-bootmenu should implement this feature.

it is possible... just need 2 new partitions ext3 on sdcard for data and system...
you can use 2nd-boot profile in bootmenu to change dev block links and customize mount settings

even i like to know tht did u tried tht?

I managed to boot from virtual system,data and cache partitions with the 2nd-boot-option of bootmenu like ep3 said.
It was a bit difficult because android-init remounts /dev so the changes will be lost but now I found a way.
And: I got recovery working for the virtual system so you don't need to prepare your images, BUT: only the wipe and restore are working. "install zip" will still affect your real system.
My scripts need some testing but after that I will release a first version.

the multboot works for me i writed a cutsom boot sh and init.rc and woila WORKS!
NOT PUBLUC because it not works for all rom

this is a dualboot rom
http://forum.xda-developers.com/showthread.php?t=1225179

So here is the first (very early) version of 2nd-boot:
http://www.multiupload.com/Z17M0WO3SU
Before continuing please make a backup of your phone!
Installation:
Just install it via CWM.
This will place the script in your 2nd-boot and replace the "CWM-Lastest"-script so it will install into the images. BUt can still use the "CWM-Stable" option for your normal system.
I've created 3 empty 300MB ext3-images for system,data and cache so you don't have todo that. Download them here:
http://www.multiupload.com/VY3U4IXRO1
Just copy the folder "fsimages" to your sdcard.
Usage:
After installing the update-zip and copying the files to the sdcard you can reboot into bootmenu, select "Lastest Recovery" and Restore an backup.
Please DO NOT install a ROM with a zip-file. Currently this will affect your real system.
After you restored your backup into the virtual file-system you can boot them with the 2nd-boot-option in bootmenu.
I successfully installed CM7.1 and MIUI-Pikachu-Edition in the virtual filesystem.

I uploaded a new version of my multiboot-script(v0.2)
changelog:
- "Install zip from SDcard" works now
- changed hook-method so it works with more ROM's(including ICS)

Thanks for your work.
Did the 2nd android system boots from sdcard?

Yes, but it's very flexible. By changing 2 lines you can let it boot from whereever you want.
I prefer storing it at the data-partition because it's over 1gb in size and my apps are using 200mb only.
I'm looking forward to better bootmenu-integration and boot-image-selection but for that I have to figure out how to compile bootmenu.

I released a dual boot version that uses 2nd-boot a few months back, hadn't have much time to improve it since.
I was using loop-back mount with /system and bind mount with /data since it's much more space efficient than just use an ext3 image.

Awesome job. I think u shud create a new thread for it. Dual booting cm7 and miui :O

Low memory

I'm running the **SMS* 3.02 by RSK team on my HTC Desire, the rom works great (I wanted the Amaze Cam) but I seem to run out of internal memory really quickly, ROM has only been on (again) for a week and I'm down to 25mb, all apps have been moved to SD.
I do have quite a few apps installed, but surely being on SD internal memory should be empty. The phone has a 16Gb SD card with a 2Gb ext partition created through recovery.
How to I get the memory back? I suspect it's going to be full in a day or 2, leading me to another full wipe

What i did to make more mem is using ''ram manager'' on the market and kill apps running in the background.

Thanks, I'm not sure how killing running apps is going to free phone storage space, though
I suspect I need to find a data2sd rom, ideally with the new cam

getting closer, I notice my Dalvik cache is ~170Mb, so taking up all that space. I installed 2 market apps to move it, the first, S2E just does nothing when IO tell it to move the cache. The second, a2sdgui, exits with the following message
"cannot start for one of these reasons
1. your phone is not rooted (it obviously is to be running custom roms?)
2. A2SD scripts could not be found o
3. No EXT partition found

Did you create a partition on your SD CARD? Does your custom rom support APP2SD (normally is natively included)?
Make sure.
Otherwise, I would suggest to try another rom to see what happen.

Don't assume that because you are running a custom ROM means your phone is rooted - the 2 have absolutely nothing to do with each other. Check that you have superuser installed, and if you do run terminal emulator and type the command su. If you're rooted you should get asked if you want to allow superuser privileges to the app. If it doesn't ask then either you've allowed (and remembered) the permission before or you're not rooted.
If an app's telling you you're not rooted then it's possibly right - always good to be sure.

Thanks, phone definitely rooted, and superuser installed (and titanium backup, which I've just used)
can't see mention of apps2sd on the rom page, though I was running a pretty old version.
Decided to do a full wipe, repartition the SD card and install a later version which has dalvik-cache to sd-ext, hopefully this will solve the problem of it filling.
Showing 174MB free right now, (+8.6Gb)
I take it if the cache does fill again I can just wipe it with no ill effects?

I wipe all my cache periodically with this:
https://market.android.com/details?...sMSwxLDEwMiwiY29tLmFhYy5jYWNoZW1hdGUuZGVtbyJd
I normally free up to 20 MB.

I am a big fan of cronmod's scripts. You can put the script in the init.d folder of the rom's .zip before you flash it, or you can flash one of cronmod's .zips immediately after flashing a ROM (before first boot).
I like them because they are fully automatic. You can install tons of apps, and they get put on your sd-ext without having to link them, or do anything to them. I used link2sd for a long time before I found cronmod's scripts. After a while I still ended up running out of space, and I would have to go back into link2sd to figure out what ELSI I could link.
With cronmod's scripts your internal folders ( like /data or /data/app depending on the script) get automatically mounted to to sd-ext. This effectively adds to your internal storage. I see it as more of a fix, while link2sd is more like a band-aid.

Hi, thankyou for the tips, yes link2sd will not give you infinite space, once you start to have a lot of apps, them continue to write some data (cache, etc.) on your internal memory and this will lead you to fill your internal memory. So in my opinion with a non rooted phone, simple move app to sd is like a band-aid while link2sd on rooted phone is like a powerfull band-aid.
About the script, it will move ALL and let you to install infinite apps? I've readed that these kind of script give you also some stability problem on some apps and also decrease speed of the phone while for now, with link2sd i've no problem at all, I moved also gapps.

Im using cronmod (int2ext+) and I haven't experienced any problems, I guess (haven't tested) they just released a script that will work with 4.2.1 The only app that ive seen with noticeable lag was titanium backup, but other than that its been great
Ive also used link2sd and that works extremely well also.

Obviously, not infinite, but on my ov I have about 180 mb for my data partition. Using the d2ext script with a 2 gb sd-ext partition means that I increase that by literally over 1000%. I have absolutely no stability problems with the scripts. Sometimes a particular rom won't boot with a particular script, but I've always been able to find at least one script that will play nice with any rom I've used.
I really liked link2sd when I started using it, but eventually running out of space again, and constantly having to link apps got old. The script will move ALL of your apps without you having to tell it what to do, and your apps will still "think" they are installed on the phone, so widgets will work fine.

thanks!!!!!
Thanks guys!!!
I m now using int2ext+ by cronmod ....works perfect!!!!
very stable and smooth...:good:

[Q] no internal space after installing rom

Need help and can't post in the thread required because i'm new.

I follow the instructions and update through m2sd then, after a few minutes reboot the phone. Next it still say's the internal memory is full, 1mb free and m2sd still showing errors with no data moved to the sd-ext. I tried a 4gig sd card with a 1 gig ext3 partition but still the same problem.
I am doing as said and wiping dalvik cache etc. I have a backup of the ONLY rom that works which is based on android 4.03 but I want the original setup back on the phone so any help needed and please, no stupid comments or immature comments as I have seen from some posts here. i'm not a child but at the same time I am not a tech-head, thanks.

I wouldn't know how to, I just trust the developer and since the rom does everything I wouldn't know where to look. the last time I tried editing a rom zip, it wouldn't install because it didn't match the original signature of the zip file. Also, because I am a new forum user, I can't contact the developer directly for some help.

Make 1 gb partition(Enough)! As the script uses 100mb of internal for every 500mb sd-ext....so making 3gb is useless.
Plus while configuring the app disable safe mode and see if that helps

Why you don't install cm10.1 beta 3. Its great and cool and stable to. Based on 4.2.2. Android os install link2sd and make both partition of fat32 by mini tool and don I have this problems when install the ROM you have then after I do this I have 8 GB SD card 1 GB fat 32 partition and other for data. Alls going good smooth stable. And a have 43 app installed on my pico and remaining internal memory showing 87 mb my good suggestion is to change ROM .
And give a time to the developers of (explorerman's rom xenon system) to make the ROM best

Did all that, I always do a complete clean of the phone before I try anything but still not working. I think, because it was a T Mobile HTC Explorer rather than a generic one that there is something hard coded into it. I see through the forums so many people having no problems at all but they have generic phones rather than unlocked phones from service providers. I am not a programmer so this is just guess work and from experience, I can't even restore the phone using an RUU because it will only accept a T-Mob one. If there a way to replace the entire software on the phone then I would but it's programmed into the chips at factory level (low level) since the phone was produced by HTC for T-Mobile. If the phone had been bought directly from HTC then there would be less problems. So far, I haven't found a single rom that doesn't have some kind of problem with this phone.
Thanks for all the suggestions but I'm guessing it's time to 'pick a window' for it and just save up for a more modern phone than trying to keep this HTC Pensioner going.

You need to wipe all partitions except sdcard in recovery, flash rom, gapps, then mod.
When you update rom, flash rom then mod again, that's it.
SD-ext needs to be a second primary partition formatted in ext4 (or f2fs if using cm12/cm12.1).
Note: New versions uploaded. Now supports all ivanich's ROMs (cm11,cm12,cm12.1).

Working great for me, but I got 2 questions:
1) I flashed the newest cm12.1 two days ago and flashed your mod (all in SD except dalvic) afterwards. Now you uploaded a New Version compatible with all ivanich Roms. Does your update make any differences for me with cm12.1? Should I reflash?
2) You just said that the mod should be flashed after gapps, I did it the other way round. Does it matter? Got no problems so far.

It doesn't matter in what order, as long as the mod is flashed after ROM because it edits ramdisk in the kernel.
Your fine with the version you have, it will act the same. You can flash the newer version when you update your ROM.

Problem with storage size
Thanks very much for the mod.
I wanted to use "All Data excl. Dalvik-Cache" and ivanichs cm 12.1 with 4ext recovery.
I was using delta-roh method on my previous installation.
I wiped all partitions except SD card. clean install the rom, then pico gapps and then this mod. Then i install my backups with titanium backup and it started to say storage is full.
When I checked the storage it was still showin 1.15gb and it was full. But installed app size was showing 2gb. I wast able to get sms because of the storage was full.
Am I missing something with the installation method?
Thanks is advance for the replies.

Same problem
Hey guys, I'm having the same problem than AKAndrew41. It gives me encryption unsuccessful screen after reboot. It keeps loading at bootloop and can't enter recovery neither. Can you help me?
Thank you!

Hi, I flashed boot.img (this file I unzipped from ivanich ROM 18.04.2015 ROM) from the computer with adb and flashed ivanich ROM 18.04.2015 from TWRP ivanich. It's helped.

You could use a root file explorer and check the properties of /idata or just enter code below into a terminal emulator. To enable terminal in cm12, goto developer options and enable local terminal.
Code:
df /idata

To enter recovery pull battery out, then reinsert it. Hold down volume down button while powering up device and it will enter bootloader, which then you can enter recovery by selecting recovery.
You must have a second primary partition (sd-ext) of your sdcard formatted as ext4 (or you can choose to use f2fs if using cm12 or cm12.1).
If your formatting your whole sdcard instead of shrinking your fat32 partition, then you need to create the first partition (fat32) first and then the second (ext4 or f2fs), otherwise they will be labelled wrong.
CM11 doesn't support f2fs, so if you format it as f2fs on CM11, you will get an encryption error and same goes I guess if you format a partition in ext2 or ext3 because it's not configured in fstab.
Did you try flashing ROM and then mod again, maybe it was a bad flash, it can happen.

I'm using your MOD Plus V3 with 2 f2fs partitions at the moment, which I created with GParted.
What does TWRP do when wiping sd-ext in recovery? If I need to wipe both is there any posibility without using GParted?
And similar, what is backuped by TWRP when doing a backup of sd-ext?

Multi swap
Hi there,
I love the work you've been doing on the sensation and I'm glad to still be using it 4 years on with the latest CM12.1. I have a problem with lagginess after multiple attempts to install CM12.1 and your boot mod v1.2. It seems to be an issue relating to the memory and swap, and I noticed running the cat /proc/swaps shows BOTH /dev/block/zram0 AND the data partition. Removing the zram0 by using the swapoff command speeds the phone up loads. Is there a permanent fix though to persist after reboots?
Thanks,
Keith

Hi Keith, zram shouldn't be active, my mod disables it in fstab.pyramid, found in the root directory.
I don't know why it's activated on your side, maybe an app or init.d script.
To disable it, you could use an init.d script.
Code:
#!/sbin/sh
# Disable ZRAM
swapoff /dev/block/zram0

ZRAM sorted
Thanks for the reply mate. I installed TWRP (from 4ext) and used it to reformat everything and start from scratch which sorted out the ZRAM0 issue.
After reinstalling ivanich's CM12.1 and your boot mod v1.2 it was much better. I'm still having intermittent lag and slow network speeds so I reverted to CM11 this morning (with your boot mod) to see if it was any quicker. Seems to be much quicker but the lag persists. Weirdly I get the lag most in the settings, and it bombs out sometimes. I'm wondering if it could be to do with my SD card partitions which were created in GParted, not TWRP.
If you've got any ideas of things to check I'm all ears.
Thanks for the kind support!

No worries, first try a lower swappiness value by lowering value in /cache/swap.conf, save it and then reboot.
Try 30 or 40, default is 60. See how it goes.
If you still have lag then your memory could be running very low, use an app or init.d script to raise minfree values slighty higher.
I don't think it has to do with your sd partitions, could be your sdcard is a little slow maybe.
You could probably check the partitions in twrp or gparted though.
If you sort it, post what you did :good:

Update: Blew everything away again and installed cm12.1 fresh without the SD-EXT mod and it runs fast and lag-free. Installed the sd-ext and lagginess came back. :-/
I had previously tried a fresh install with another SD partitioned by TWRP, made no difference to lagginess. Lower swappiness values seemed to have a minor difference but still laggy.
The lagginess seemed to be mostly when loading from disk. Applications in RAM seemed to run fine until they needed to load something. Downloads very slow on WiFi or 3g, titanium backup very slow too. Strange...
It would be nice to get it working but this is a tad baffling. Thanks for your kind support!

Seems to me that your sdcard is not fast enough, what make and kind of card do you have?
SDHC or SDXC and UHS-I or UHS-II
I have a Sandisk Ultra SDHC UHS-I and it's only just fast enough for this mod, I need a faster one really.
I have no issues with download speeds with wifi, not really related to mod though, could be slow at writing to sdcard.
Titanium could be slow due to slower writing speeds on sdcard too as it has to build dalvik-caches on sdcard when restoring apps.
Edit: Can you try BOOT-MOD-1.1.zip, it's the non-plus version. It would be good to know if you still experience lags with it, if you do, then sdcard is not fast enough, otherwise could be something to do with the plus version, cheers.

I'm using a Lexar 32GB class 10 SDHC, had no issues with it. I ran the A1 SD card benchmarking tool and it measured reads of 17 and writes of 11 MB/s. The internal flash reported speeds of 25MB/s read and 7MB/s write by comparison.
I'll try the BOOT-MOD v1.1 and report back...
