To be honest I never checked CWM Recovery recently to confirm that. I saw the two swap options listed at the top of this thread, so thought that those where the currect options - they have obviously been updated since then. ;)

galaxy s2 internel storage issue

I have been trying to dual boot siyah kernel with resurrection ROM.

When I try to clone 1St to second it says I don't have enough space which

Would be correct as I need 2.5GB internal when I only have 1.97GB.

has anyone got round this problem?
[Galaxy S II Q&A, Help & Troubleshooting] Many40:
Yes, it's almost correct. For 2nd rom you need: 2 GB for /data partition, 0,1 GB for /cache pertition and 0,5 GB for /system partition. In total about 2.6 GB
[Galaxy S II Q&A, Help & Troubleshooting] Cudge82:
So how do I get around this issue?
[Galaxy S II Q&A, Help & Troubleshooting] Many40:
There are several ways to free some space on internal sd:

1. If you have any files in /sdcard/LOST.DIRfolder - delete them

2. Move whole folder /sdcard/DCIM do your external sd card. Afterwords change settings in your camera app "storage" to "memory card". Then all your pictures or movies from camera app will be stored to external sd.

3. If you are using TitaniumBackup app move the foldet to external sd. Also change default location of backup files in TitaniumBackup app settings to the new one.

Good work!

I´ve read this guide and I really like the clarity of instructions. Now to my question: would it be posssible to "port" this tutorial so that it works for my S3 as well?
[Galaxy S II Q&A, Help & Troubleshooting] Many40:
Hi, I think you know that dual booting is not implemented yet for your S3 phone. According to OP of Siyah kernel thread Dev is working on that - dual-booting is still on his "to do" list. So I suppose when it is ready he or droidphille will prepare a guide for that. If this one prepared for S2 will fit to S3? Who knows, maybe, depending on how gokhanmoral is gonna port dual-booting to S3. Regards

[Galaxy S II Q&A, Help & Troubleshooting] ares05:
Hi Many40, thanks for the awesome guide, I'm about to take the plunge. I've spent the night reading the whole thread and something seems a lil unclear to me.

1. If I update my primary ROM without wiping data my second ROM is safe? Otherwise, since it is stored in my internal SD, it will get deleted?

2. If the previous answer is Yes, then to solve this problem all I have to do is make a Nandroid backup of secondary ROM and restore after I've done wiping and installing primary ROM?

3. And finally most devs recommend factory reset, wipe everything before installing a new ROM. So, if I have to follow this procedures for my secondary ROM do I just wipe cache & Dalvik memory or do I remove my old secondary ROM and install new ROM completely new as secondary ROM??

Sorry if it has been answered before, just seemed a lil unclear to my "new to dual booting" brain. Thanks!

1) As long as you stayed with the same kernel, even you full wipe by cwm recovery on the primary rom, the secondary rom still there.

2) nandroid backup is a good practice when you installing a new rom.

3) for installing a new second rom, I always removed existing second rom, wipe cache and dalvik cache in second rom option.

After installing the second rom, I always run extweats to remove root fellow a reboot. because some rom used different superSU/superuser. By doing this, my first and second rom will be on same superSU/superuser. Finally just restored back my data by titanium backup. My second rom will never have SOD, self reboot, fc, wifi and GPS problems. I tested nearly all the versions of aokp by bajee11, RR and PA ROM with no problems.

[Galaxy S II Q&A, Help & Troubleshooting] Many40:
Hi, first of all, thanks for treating me as an OP of this thread but unfortunately I am not, it's made by Phistachio. I am just actively try here helping the others sharing my experience and some knowledge. In addition to what timberwolf60 already wrote (maybe to make it even more clear for you) I'm gonna add a few words.

As I already wrote some pages ago 2nd rom uses following partitions:

/data partition - .secondrom/data.img as mountable img file on sd card

/cache partition - .secondrom/cacha.img as mountable img file (in the same folder)

/system partition in hidden partition: /dev/block/mmcblk0p9

1st rom uses different partitions with one exception: it writes some temporary files (during flashing phase) to system partition of 2nd rom (overwriting system files of 2nd rom). Later on these temporary files are never used) but unfortunately /system partition of 2nd rom becomes corrupted causing that your 2nd rom is lost, even /data and /cache partitions are not touched. What is important - it happens only if you flash as 1st rom a new stock TAR rom via odin or mobile odin. From my experience flashing as 1st rom customized rom in ZIP format from CWM recovery or restoring nandroid backup doesn't affect 2nd rom (under condition that they contain Siyah kernel, because if not you have to flash it again afterwords). However before you flash a new 1st rom it's good routine to make nandroid backup of 2nd rom. So summarizing, wiping system/data/cache of 1st rom doesn't influence 2nd rom at all. What does it's if 1st rom stores temporarilly anything to hidden partition /dev/block/mmcblk0p9 - TAR stock roms are concerned for sure. What I already tested is: flashing NeatRoms is safe for 2nd rom, other roms you have to check by your own.

2nd Rom files

Hi I'm new to dual boot thing! I tried to install a second rom using the guide provided in the first post. Everything seemed to work fine but after the installing process, it says no 2nd rom is found. So I decided to remove the 2nd rom but for some reason my internal sd card space is still used up even after I chose the remove 2nd rom from the dual boot option in the recovery mod. Just would like to know how to remove the 2nd rom files and get my internal sd space back! Any help is appreciated. Thanks
[Galaxy S II Q&A, Help & Troubleshooting] Many40:
Strange, seems that installation proccess failed for you for some reasons. What Remove 2nd rom command does is: removing files from sd card (data and cache partition) and formats system partition. If it doesn't work for you just do it manually: delete /.secondrom folder from internal sd card and go to CWM recovery /mounts and storage and use option format /secondrom_system. Also on sd card check LOST.DIR folder if you have any corrupted files, you can delete them as well. When you try installing 2nd rom again, make sure you have about 2.6 GB free space on internal sd card. Regards

[Galaxy S II Q&A, Help & Troubleshooting] Many40:
Strange, I had similar problem when flashed in parallel rom and Siyah via mobile odin. But I don't have any issues when I flash from CWM recovery. So I recommend you to download zip versiin of Siyah and go to CWM recovery, wipe cache and Dalvik and flash kernel from "install zip from external or internal sd card" or something like that. It should work. If you still face any issues some guys claim that Ultimate kernel cleaning script may help. I personnaly never used it and normally it is not required for kernel flashing. Regards

It did NOT work. Thanks for the suggestion. I also used the kernel cleaning tool. I also did the fix permission in Siyah.

please advise me on this issue.

thank you.
[Galaxy S II Q&A, Help & Troubleshooting] Many40:
Hi again. If you flashed something not from dual boot option of CWM recovery, it was flashed definitely to 1st rom. So if you flashed a mod not compatible with 1st rom - it's done with all consequences. I wrote recently that before flashing anything new it's worth to make nandroid backup.
[Galaxy S II Q&A, Help & Troubleshooting] 1981ts:
thanks for the info.

so that means the 1st rom is gone. swaping would work then?

now what i could do is, swap 2nd rom with 1st rom? or clone 2nd rom to 1st rom?

thank you.
[Galaxy S II Q&A, Help & Troubleshooting] Mohamedselim:
Swap as first rom and second rom exchange places

Clone as second rom will take place of first rom erasing it so you will have 2 second roms

Choose do you want to sacrifice the first rom completely (clone) or put it second rom (swap)

Hi,

They share only:

1. kernel

2. modem

3. Additionally you have access from both roms to:

- folders/files which you stored on external SD

- folders/files which you stored on internal SD but they are not part of ROM partitions, eg: pictures/movies from /sdcard/DCIM

The rest including all you have mentioned is unique for both roms.

[Galaxy S II Q&A, Help & Troubleshooting] Many40:
If you really decide to do that it will work but there are at least a few ways to achieve this. I recommend to you following:

1. nandroid backup of current rom

2. clean installation of your new pa rom

3. restoring your previous rom from the backup as the 2nd one from CWM recovery / dual boot options

Moreover I recommend to update your kernel to the latest 4.1.5.

So I have to verify that both ROMs support the same Kernel.....

I installed Jelly_king 1.5 as 1st and Rootbox 2.7 as 2nd,

When I updgraded to Rootbox 2.8 - it stopped working. Probably because it doesn't support DorimanX kernel but only Siyah.

BTW - it seems Rootbox 2.7 was better in terms of battery and many nice features as well.

It's normal behaviour if you flashed one of the latest releases of CM10 roms. They have new mali drivers included and most of custom kernels are not compatible yet (including Siyah).

Hi Guys,

I'm wondering if anyone can help me with a small problem please? Ok, for the last couple of weeks I've been running cm9 as my primary rom and cm10 as my secondary rom, no problems at all. Basically I wanted to update my cm10 build to the latest nightlie and it looks like the only way I can do this is to make cm10 my primary rom? So last night I cleared 3.5gb's of space on both my SD card and on the phone and did a rom swap to make cm10 my primary rom. It took a few minutes and it looks like everything was successful. Unfortunately, I've tried about 3 times to update my cm10 build to the latest one and all I've been getting is a black screen on reboot. I tried just the update without reinstalling siyah and that's the only time it loads up but I don't have CWM and obviously it's the stock kernel which will mess up my dual boot.

I've tried wiping cache/dalvik then installing the latest nightlie, reinstalling siyah then rebooting, black screen everytime. Am I doing something wrong? If someone can explain how I can update cm10 and keep my dual boot files etc..as they are and do everything cleanly and properly it would be much appreciated. Preferably without doing a full wipe and losing all of my apps/settings and stuff if possible? Sorry for the long post.

Thanks in advance
[Galaxy S II Q&A, Help & Troubleshooting] prnvp23:
AFAIK current version of Siyah Kernel does not support CM10 nightlies after Oct 2nd, something to do with Mali driver support I guess, you can update to Oct 1st version of CM10, nothing newer if you wanna keep dual boot. Hopefully a Siyah update is on the way :)
[Galaxy S II Q&A, Help & Troubleshooting] gargon01:
Thanks a lot for the info. I'm on the Oct 1st build already. So I shouldn't do a full wipe to install a newer nightlie as it won't support dual boot at all right?
