r u getting the multirom screen at boot? and r u selecting the correct boot location?

if yes, maybe its updater script uses some special stuff. i'll see. Currently my app removes mount and unmount statements, and replaces format statements with rm -rf.
[Optimus One, P500, V Themes and Apps] lipe082:
I think multirom menu dont appear on boot will try with cm10 its alot more useful but after prepare zip i have to flash in recvery? Because with sense app didnt flash rom only change updater script well will see now with cm10
[Optimus One, P500, V Themes and Apps] kawaiiDango:
Did u use the "create from zip" option? Dont use that. You have to flash in normal way from recovery. The app doesnt flash ROMs. It just modifies the updater script and boot image.

Multirom should have got embedded with the ROM's boot.img, so, after you flash in recovery, multirom screen should show up at boot.
[Optimus One, P500, V Themes and Apps] lipe082:
So after prepare zip flash as sytem rom and then restore backup to stay with both roms?? Im getting confused.

So i have to assume that app only gives multirom options to others recoverys is that it? If so already got it how to work ;)
[Optimus One, P500, V Themes and Apps] kawaiiDango:
are you talking about nandroid backups? You dont need any kind of nandroid backup. It modifies the updater script so that the rom is flashed directly to /sd-ext/multirom/rom/

It mounts /system as /sd-ext/multirom/rom/system, /data as /sd-ext/multirom/rom/data and so on.
[Optimus One, P500, V Themes and Apps] lipe082:
let me wake up because realy im getting confused what i did now was with cm7 i change script then reboot to recovery and install that zip and replace my cm9 that was in system lool...

its better i wake up first...
[Optimus One, P500, V Themes and Apps] kawaiiDango:
hey theres an error. linux line breaks have got mixed up with windows line breaks. I dunno how you managed to flash. amon ra gives me a parsing error.

expect an update soon.

btw, did u flash the original zip or the modded zip? the modded ones have a prefix "mrom-" (
[Optimus One, P500, V Themes and Apps] lipe082:
moddeda and amonra as well ,and now when using stock with dt script cant recgonize my sdext lol

should not appen but no stress waiting for your update ;)
[Optimus One, P500, V Themes and Apps] kawaiiDango:
i tested cm10, Dynamite and aokp sucessfully. Sense didnt work and i have no idea why.
[Optimus One, P500, V Themes and Apps] lipe082:
Ok i see the zips that app does but they are smaller than the normal zip and it gives error when flashing the rom. What am i missing does the app execpt of the bar fulling when changing updater script says done???
[Optimus One, P500, V Themes and Apps] omidreza:
sorry for my question...i need your app and i'm a bit confused. i want to have the cm7 as base and daily rom and try the aokp for a few hours and get back to cm7. what should i do?
[Optimus One, P500, V Themes and Apps] kawaiiDango:
works fine here. zip can be smaller due to different compression ratio. but there could be other reasons also. Can u open the zip in file manager? Did u complete the "embed multirom" step? did u mount sd-ext in recovery before flashing?
[Optimus One, P500, V Themes and Apps] lipe082:
I can open zip from file manager i mount sdext but i always get a status6 error.
[Optimus One, P500, V Themes and Apps] glimmling:
It seems, you havn't updated to the latest release.

arnab321-Tasssadar-MultiROMMgr-v4.1.apk in the first post.

The status 6 error is the same one I got with v4.
[Optimus One, P500, V Themes and Apps] kawaiiDango:
v4.2 released

It is caused if u dont mount sdext in recovery before flashing. But u wont have to do it anymore after this update.

This is the last update before i go to college. I wont be able to use a computer (except the college computers). We arent even allowed to keep laptops for the first yr, so i wont be able to work on it anymore.

Changes:

[*] If u prepare zips using this version, script will mount sd-ext automatically before flashing in recovery.

[*] if /sdcard/multirom/multirom.zip is found, it will use that for preparing zips.
[Optimus One, P500, V Themes and Apps] DistantFather:
I want to use this but unfortunately I am a bit confused on how this actually works?

would you mind if you provide a rather simplified instruction for melon heads like me?
[Optimus One, P500, V Themes and Apps] kawaiiDango:
Simplified instructions:

I guess you already have an ext partition on sdcard. (else create it from recovery, gparted, or any partitioning software). A typical rom takes about 200-250mb if you keep minimal apps.

I also assume that you have multirom (not this app) installed. Else simply use the app's "check for updates" to install multirom. (Or maybe download the flashable zip from tasssadar.github.com )

-backup your current boot image with the app. (I'm calling this backup as rom1.img)

Steps to flash a new rom to sdcard:

-use the "prepare zip" menu of the app, choose the rom zip you want to flash on sdcard. (Sense roms will not work)

-it will take some time as it extracts, modifies and repacks the zip. When the preview of the updater script is shown, just press "save".

-after the progress bar completes, you will see the "embedding multirom" screen. If you are a first time user and see a prompt about choosing multirom.zip before that screen, just choose "download from internet".

-At the "choose boot location" prompt, select "sdcard".

-the boot image of the Rom will be stored as "tmp_boot.img" (all boot image backups are stored in /sdcard/multirom/). Just rename it to something meaningful with a file manager. Let's say I renamed it to Rom2.omg. You will need this to boot into the Rom later.

-go to recovery and flash the zip. (The modded zip will have the prefix "mrom-").

-reboot. Your Rom in sdcard should boot now.

Switching Roms:

-to switch to Rom on internal memory, go to "backup/restore boot image" on the app, select rom1.omg, choose "internal memory" and reboot.

-to switch to Rom on sdcard, do the same thing with rom2.img and choose "sdcard".
[Optimus One, P500, V Themes and Apps] Ecuadude:
Sorry for the noob question :rolleyes:... But how would I flash ics gapps to cm9 using multirom? My main rom is gingersnap right now but when I tried to flash the ics gapps to cm9 it mounted system and flashed it to main rom . Do I need to mount sdext for it to flash on sdcard rom? :confused:
[Optimus One, P500, V Themes and Apps] DJBhardwaj:
Removed
[Optimus One, P500, V Themes and Apps] cure25:
Nope u even not need to prepare zip.just go to multirom option in recovery.there is option

Flash zip( do not use for roms)

Select it and now select gapps which u want to flash.u r done
[Optimus One, P500, V Themes and Apps] Ecuadude:
Thx a lot. :thumbup::D it worked nd now I'm enjoying cm7+aokp lol. It's a lil slow but I can deal with tht
[Optimus One, P500, V Themes and Apps] DistantFather:
This should be posted on front page

Thank you!

This should be posted on the front page as not everyone clearly understands what was written there.

One last question...what does doing this thing (having rom on sd card) does to the overall performance of the phone?
[Optimus One, P500, V Themes and Apps] DistantFather:
Hey Dj!

does this work on your MIUI rom? your rom being the one on SD card?
[Optimus One, P500, V Themes and Apps] kawaiiDango:
Use the prepare zip option in the app if u want to flash anything to sdcard.then flash the modded zip.
[Optimus One, P500, V Themes and Apps] kawaiiDango:
Test it. I can't do anything now as I'm landlocked with my phone and a slow 2g network, and no laptop for a whole year in this hostel.

Edit: umm what??? I never made any miui Rom. :D
[Optimus One, P500, V Themes and Apps] DistantFather:
sorry, i didn't notice the "quote" on DJ was not present..it was for him
[Optimus One, P500, V Themes and Apps] DJBhardwaj:
Yes, I tried and it worked. Well actually it would work flawlessly if you have a class 10 SD
[Optimus One, P500, V Themes and Apps] DistantFather:
How long does it take to boot on sd card? its been 5 minutes for me and still "booting from SD Card"
[Optimus One, P500, V Themes and Apps] Sandipkim:
Normal time...!

If you have flashed any ICS rom(Except Aokp) directely to SD..then it won't work!!:silly:
[Optimus One, P500, V Themes and Apps] kawaiiDango:
In that case, pull battery, switch on, and at the multirom screen, press misc.> reboot

It's something similar to the charger screen bug in older hephappy's Rom, and happens sometimes only with ics (even if you keep it in internal memory)
[Optimus One, P500, V Themes and Apps] Dobomi:
Am I missing something? I'm on Amonra recovery, stock rom (v20h) + ta kernel (on internal memory) and cm7.2 (on sdext partition). I use multirom v19 and this app's 4.2 version. Everything works fine (with 2 ROMs). From the quotes above should I understand that I could use more than one ROM on the sdext partition? How do I do that? I tried to move with this app the active rom to backup, but it didn't let me do it. Any advise? Thank you!

Restore APPS

Hi Arnab,

Today i tries your application, it truly amazing and simple to use by following steps mentioned by you in the post, on my phone i had AOKP ICS and now on my sdcards i have HepHappy RC2 ROM and they work flawlessly.Thanks for this application and keep up the good work.

I have few question if you could answer them:

1)Is there any way that all the apps i have installed on my phone ROM(internal memory) will be available for the new ROM i installed using sdcard?

2)If i have flashed Gapps for phone ROM will i have to flash again for new ROM in sdcard?

3)While switching i got it to boot into phone ROM choose option internal from restore menu and for ROM in sdcard use sdcard option but what i didn't get it is when to choose option 'Backup ROM in sdcard'

4)I want to use CM7 ROM from my sdcard but i read somewhere in Tasssadar's MultiROM forum is people lost root permissions and are not able to root CM7 again.So is that mean if i flash CM7 from my sdcard i will loose root privileges and will not be able to root my phone again and will this affect my phone ROM(internal memory ROM) also and will loose root on that also?

5)How to use more than 2 ROMS means if i want 2 or 3 ROMS on my sdcard for flashing what are the steps for that?

Please answer my questions so that i can fully utilize this application and thanks in advance for your support

An Arnab fan

[Optimus One, P500, V Themes and Apps] sifonaru:
1) Flash a2sd script in recovery and your apps will appear in all roms (phone and sd card)

2) Yes, you need to flash Gapps individually for each rom

3) Backup ROM in SDcard - it will move your current sd card ROM into a new folder. So, if you want to install a new ROM in sd card, use this option first - then go in Recovery and choose Create zip from file. Reboot and try to boot from SD - it will appear two options in the menu (the new flashed rom and the backup = the old rom)

4) I never encountered this problem and I flashed a lot of roms.

5) >> Read 3) and just repeat the Backup ROM in SDcard step everytime you want to flash a new rom in SD.

[Optimus One, P500, V Themes and Apps] anand313:
Thanks sifonaru for the reply they are very informative.

For the point 5 and 3 above i got it when i click option 'Backup ROM in SDcard' it will move the current ROM on sdcard to some folder in sdcard and after that i need to again repeat same steps for flashing new ROM on sdcard like prepare zip and then flash ROM with mrom- as prefix.I am i right?

But i have questions

1) Do i need to create backup image of my current sdcard ROM again before doing this or old one which was created first time i flashed ROM on sdcard will still work?

2) After selecting option 'Backup ROM in SDcard' when current sdcard ROM is moved to some sdcard folder, will i be able to boot that ROM from sdcard from the image i saved earlier from backup/restore menu option?

(A) Also i wanted to know since on original Tasssadar's MultiROM forum its mentioned in the limitations that both ROMs should use same Kernel is this limitation applies to this application also.I wanted to use both AOKP ICS ROM (in internal memory) and CM7 (in sdcard), but both of these i suppose have different Kernels, so is it possible to flash ROMS with different Kernels.

(B) Could you tell me when to use option Manage ROMS on sdcard and what will it so, i know in description something is written but if you can elaborate it it will be quite useful for all of us

(C) Is it possible to flash separate Kernels on ROMS installed on internal memory and sdcard via this application?

Thanks in advance for your valuable inputs and sorry for bombarding with questions.

[Optimus One, P500, V Themes and Apps] lipe082:
well its almost yes to all your questions i will try to explain,

with this app you can have roms with diferent kernel and the boot.img you made by that app will always work wih the same rom no need to make one if you already have one for a rom,plus you can simply extract boot.img from rom you want and place in multirom folder in sdcard it will work the same just rename...

you can only use one rom in system and lets say the other 2 in sdcard,when you choose make rom, you wait until bar is full press save and choose sdcard reboot to recovery and rom that app made will install in sdext after you have the rom in sd install the app again click on boot.img of rom you have in system choose location system(or sdcard main or sdbackup depends on what rom you are using)and reboot phone you re back to the rom you have now...

after you have first rom in sdcard use app to remane the folder it makes with the rom to whatever you want...

if this is well done you wont loose you internal data or anything but do a backup of your rom first just in case and try it its very useful......

im not very good explaining stuff but with the first page tuto. and this tips i think you get the picture...
[Optimus One, P500, V Themes and Apps] 4wd vege:
Hi this looks simply amazing.

I have used the original multi rom before but found it a hassle to get roms with different kernels working.

Currently I have a 1gig ext 2 partition for David nt apps to sd mod.

If I put another partition on the sd card does multi rom know which partition to put the rom in?

By the way great work arnab123.
[Optimus One, P500, V Themes and Apps] lipe082:
How do you do 2 ext that would be great 2 ext one for apps of internal and another to rom.

I think its not possible to have 2ext in same sd but share how to make it.
[Optimus One, P500, V Themes and Apps] Sandipkim:
You can make two ext2 partition using mini partition tool from windows:good: but I don't now how it gonna be set up for your using purpose!:p
[Optimus One, P500, V Themes and Apps] anand313:
Last few questions and then i am done

Thanks lipe for valuable reply, but some questions still remains, it would be great if anyone could answer these:

1)Could you tell me when to use option Manage ROMS on sdcard and what will it so, i know in description something is written but if you can elaborate it it will be quite useful for all of us

2)Is it possible to flash separate Kernels on ROMS installed on internal memory and sdcard via this application?

3)After selecting option flash/backup ROM option in app i choose sdcard ROM image and click Backup ROM to sdcard, but after that message is displayed on screen saying 'Backup folder is empty'. Please let me know how can i backup my sdcard ROM so that i can flash another ROM in sdcard

4)How can i uninstall the ROMs i have flashed on my sdcard, do i ned to just remove image file and ROM created by prepare zip with mrom- as prefix or there is some other method to uninstall sdcard ROM?

5)Is there any way to sync contacts/messages/call logs across the ROMS?

6) I have observed that when i am using Sdcard ROM phone usaually heats up, i have not overclocked it by default its 320-600mhz, governer-powersaver on hephappy RC2 ROM, has any body observed the same?

7)How to uninstall multiROM app just in case, is it same as removing any app from phone or some other process is there.As I have seen a download link on original Tasssadar's MultiROM forum for uninstaller.Do i need to flash this zip file as any other file from recovery?

8)I have came across one such app known as bootmanager in google play store which alows multiple ROMS on phone but currently it supports HTC phones only.It has a feature called sdbooster because of which ROM on sdcard runs smoothly, can we have simmillar feature in this app?

9)While having one ROM in sdcard if i use option prepare zip from the app the follow the same procedure saving after progress bar ends save and then image of that ROM will be saved in sdcard/multi ROm, will this overwrite image of my current ROM on sdcard

Thanks all for your support. I know its i am going deep but it will surely help other users who want to try this app without facing any problem

Using a regular partition manager rather than using CWM, you could presumably make whatever partitions you please. The question is what the various programs will make of them.
[Optimus One, P500, V Themes and Apps] 4wd vege:
How to make it?

Very easy if you have a Linux machine.

Connect through usb.

Drag all contents to another folder.

Format sd with gparted.

Partition with gparted.

Copy all files back.

Turn off usb conection.

One issue I am facing is with "Manage ROM's on SD"---> "Move Active ROM to Backup".

When I try to backup my current rom which was booted from SD card, it says "Cant move active ROM to backup!" and "Backup folder is empty!"

Please help me to manage this backing up of current ROM.

Thanks again!

The same here: I couldn't move active ROM to backup.

Booting from one ROM to the other requires 5 or 6 clicks. I automated the whole process using Tasker and now I boot in just one click: I launch the app (Multirom Manager) and Tasker does the rest.

I created two Tasker profiles, using as first context Application (Multirom Manager) and as multiple alternate actions Wait (from Task category) and DPAD (from Input category). Of course, there are 2 profiles: one to boot from internal memory and the other from sd-ext.

Excellent app

Now I have three ROMs ;)

-Internal memory: GB stock + custom kernel (basic, very light, for daily use) - 157 MB free memory

-sd-ext (main rom): CM7 (bloatware removed) - office and internet oriented - 252 MB size

-sd-ext (backup): CM7 (bloatware removed) - media and navigation oriented - 244 MB size

I have placed on the homescreen of each ROM 2 Task Cuts (shortcuts for Tasker tasks) for the purpose of booting directly to one ROM or another. It takes 65-75 seconds from the time I press the Task Cut icon up to the moment when all the apps of the newly booted ROM are fully active. It's faster when I pass from sd-ext to internal memory.
