dual boot - Galaxy S II Q&A, Help & Troubleshooting

I'm in need to dual boot GB & JB.
I'm currently using wanamlite rom details link: http://db.tt/r9A8Kkmh
I tried to clone my current setup/rom (as an update.zip) using philz but I get errors/cannot complete.
Can you suggest an alternative way?
I tried to generate/clone an update.zip of my previous setup/rom (that'll be the 2nd booted rom) though via philz I get error no .tar file found from the nandroid backup once selected.
I see in rom manager there's an option to backup current rom, though will it be an update.zip and/or will it work as a dual boot file?
Any help appreciated, as I'm cautious as I don't want to lose my current rom/setup.
I'm going to use the dual boot method/work around from this link http://forum.xda-developers.com/showthread.php?t=1882884 though need to generate the apt file(s) first.

ok I believe I backed up my currrent rom/setup via rom manager, as now I have a new file with today's date, though as my phone rebooted automatically can I be sure I now have a working backup of my current rom/setup?

As with most backups, the only way to test is to restore and see. You could copy the restore to a pc and open it in any archive tool to examine the contents and check your happy with the result. I've never bothered tbh.

I downloaded an alternative kernel to dual boot and it didn't work with wanamlite rom so I bit the bullet & tested the nandroid backup that I was unsure (had roblems with earlier), & it worked [thank the backup reminders].
However, is there a known kernel(s) I can flash to dual boot (compatible with both GB & JB) with wanamlite rom without losing all the goodness n speed of the rom?
Also, as I had issues using philz cwm 4 to make a clone of my current and previous setup/rom datas as an 'update.zip', can anyone suggest an alternative app to generate an update.zip of my setups/roms (as I'd prefer not to make update.zip files myself).
Help and your time (anyone & all) is appreciated.

The only way you're able to do this that I'm aware of is by using that convoluted method you linked to in your OP. There's no way to simply just flash a single kernel & do it, because you're talking about different frameworks (GB/JB), the kernel has to be capable of working with both roms you're using (which is how dual booting works with Siyah).
Edit - Another convoluted way to possibly achieve this (and you'd have to be really keen/motivated to want to do it) would be:-
Say you're currently running a JB rom, you back this up in CWRecovery, then you do a clean install of the GB rom you want to use. You use the GB rom, then when you're finished doing what you need to do with it, you back it up in CWRecovery. When you want to go back to JB, you restore your backup, use JB, and back it up again when you're done. Then when you want to use GB again, you restore your backup, use GB, back it up again, etc, etc. Obviously you'd have to be really motivated to want to go through this much trouble given you're going to have to backup/restore a lot whenever you want to switch roms. But I can't think of another way to do it other than that method in your OP.

Yeah that was my thinking last evening, if I couldn't find or get info on a suitable kernel.
I'm going to read the other method again and decide what to do.
Thanks.
[edit] after reading the alternative method again I guess it comes down to 'timings' on either method; to complete.

Yep that's it. Whichever method you choose, it's going to take a bit of 'messing around'. You have to weigh up the hassle Vs how much you need to use the GB rom I guess.
No probs. Good luck

[Q] Help with wrong flash!

Hey all I'm new to the community and understand how to flash and what not but am not as knowledgeable when it comes down to the details. Recently I flashed Trigger 3.2 and I love it! However, I wanted to try to apply the gps fix that BT provides in his OP, and for some reason I thought that I could download it straight to my phone and flash it via ROM Manager. Anyways, I went into ROM manager and it seems to have flashed 3.2 again, except that I am now missing LauncherPro, all my apps(including Titanium Backup) so I have no way of restoring ROM Manager and attempting to revert to my previous flash. I know that I made a backup of 3.2 except Im not quite clear as to what a nandroid backup is, so I cant say for certain if I did that. If anyone could please give me some advice as to how to get back to my previous flash of trigger 3.2 (with all my apps and data) it would be greatly appreciated. Thanks in advance!
first, check this website about Nandroid. http://www.simplemobilereview.com/android-rooted-what-is-nandroid-backup/
I dont think its possible to get your backup back because the backups on rom manager is saved in a folder called clockworkmod.... which is in your internal sd card. Soo next time you change roms, backup your rom, and put it on your computer. Or nandroid it.
Hope this helps

Thanks for the response! I figured I wouldn't get my ROM back, but I did have a backup of Trigger 3.0 so I just flashed that and will reflash Trigger 3.2 tonight
You should be able to enter clockwork recovery via three button method and restore through the nandroid restore option

The plan is to choose a ROM which suits your preferences, e.g. no homescreen lag, better camera apk, better access to the CPU. Try a few, I use Villianrom, which suits me really but there are loads more.
Enjoy

your /efs folder is in comparison to apps, data etc. the most important thing to backup since it is the only thing that cannot be restored without a proper backup if it is screwed up by a bad flash. it basically contains your product code, imei and other sensible phone related data. you can backup it easily with hellcat's kTool app from market. For safety reasons you should copy your /efs backup img from your sdcard to your pc afterwards.
Concerning your other questions, just read through the few stickies in the general and android original dev. section. all what you look for is explained there very detailed.

If u rooted with cf kernel n haven't flashed another then yes, up+home+power >back up. Use hellcats k tool to back up efs (its on market or his thread in dev section) titanium back up is the 1st thing that comes up if you search 'titanium' on market the pro version is costs but is worth it.
Seriously tho, if you're new to android and have never rooted, give it a few weeks first otherwise you won't know what is 'better' and if you don't and end up having problems with roms you'll end up crying that you should have got an Iclone.. Just my opinion from observing this forum for a while

hi,this rooting seems pretty confusing as i used to be an iphone user and jailbreaking was simple but this seems to be difficult to follow,ive been looking around the forum for step by step guide on how to install roms etc but just cant find them,would like to test this out to see if it was worth rooting but at the moment its done nothing for me or the phone its just added another few apps,it seems to me like its a lot of hassle to get different roms etc onto the phone & whats radio etc do i need to update other stuff when i try to put roms on & kernels whats that all about ????sorry chaps but im clueless to all this stuff maybe i should have stayed with apple.
and the efs backup has been done with hellcat & when connected to pc there is no backup file on my sd card ??

My advice is to stay away from flashing ROMs, kernels and rooting.
Use it like you used your iPhone, install games and apps from the Android Market and enjoy your phone.
Unless you've seen something you particularly want from any of the above, the risks for you are not worth it.
thinking that myself mate but how do i put the phone back to the way it was before i rooted ?
how to remove the root & go back to original way
As far as I can tell, you haven't said how you rooted - looks like you flashed a different, pre-rooted kernel. There's not a big risk staying rooted, just take extra care if you install something and you get a popup on your phone telling you it's asking for root (superuser request).
it was this
DooMLoRD_v2_ROOT-zergRush-busybox-su.zip
and installed zimage to my sd card and installed onto phone so i have superuser and darkyrom2 installed ive done nothing else.
mucking around with roms & kernels etc seem a load of hassle & dont want to destroy the phone with wrongly installed roms etc & what happens when a new update come out through kies ? do i just install it or what ?
can i not just remove the root by doing a factory reset or something ?
Of course you can easily completely revert back to your original set-up. For doing that just type *#1234# in your dialer and post here the output. I or someone else can point you to your original rom.
BUT you will never get a taste of in my opinion the greatest advantage of android: it's customability.
I promise you, you won't regret the effort it takes to educate yourself a bit about the basic knowledge you need, to do all the cool stuff which is only possible rooted. It is enough to spend some time to read regulary here on xda and you will see that everything is really not that hard. You don't have to fear, it is almost impossible to brick your phone if you just have a backup of your /efs folder, don't flash the firmware of another device on your phone and don't disconnect your usb cable in the one second a different bootloader gets flashed. I have flashed and hardcore abused my sgs1 more then 500 times (no exaggeration, i am a dev for sgs1 ) and my sgs2 also very often. Everything ( while testing stuff i went through scary errors and a literally death phone more than once) is recoverable except in the three situations i mentioned above. And you can ALWAYS go back to stock later on no matter what you have messed up.
Have a look again at the content of your sdcards (also in folders and subfolders), the efs.img or .tar has to be somewhere there, save it on your pc and the party can be started

And because i am a nice guy and don't want you to go back to apple here my advice for your first custom rom :
1. Follow exactly the instructions there: http://forum.xda-developers.com/showthread.php?t=1103399
Take your time to read through, everything is explained very well
2. Then you are ready to flash your first custom rom: http://forum.xda-developers.com/showthread.php?t=1288850
this is in my opinion the most stable atm. Read through the first posts, download the 2.9 zip from the post, copy it to your internal sd
3. Switch your device off and boot into recovery by pressing and holding volume up, home and power button at the same time until samsung gti9100 appears on the screen (about 5 sec.), then release the three buttons and you are in recovery mode. You can navigate with vol up and vol down and power or home button in the recovery mode. Navigate to "install from sdcard"/"choose zip from sdcard" and then select the file you have downloaded. Confirm and relax. That's all... easy or?

From now on you can easily forget about kies, roms here will mostly provide newest firmware long before it is out via kies. Also with odin you can always much more comfortable flash the same firmware as comes over kies.
You can flash any rom you want as long as it is for your device (gt i9100).
As i said, take your time and read across the forum and always follow the thread about the rom you run and your knowledge will improve from alone have fun bro

Downgrade to GB using CWM restore?

Had a very bad experience when i upgrade rooted GB to stock ICS using wifi (w/o pc connection). During the 1 week of using ICS, my s2 got tons of issues, ie, no app works properly, battery drain faster, consum more ram etc.. worst, could not root! Eventually brought to samsung svc ctr to restore a brand new GB.. root the GB again & working well till now..
However i really want to explore the latest JB roms, in case of the flashed rom got any issues, i want to know how to restore to GB (backuped using 'CWM app') using CWM restore or anything else?
Which likes using Ghost to backup/restore a setup windows sys..

Rooted with Current kernal: CF-Root 5.0
Can any1 also kindly advise me what are the important things/steps i need to take note, when flash to JB rom? I dont want to mess up my lovely s2 again..
Thanks in advance!
1. Try to backup gb and then install ics stock rom on your phone with odin, you can find the guide on the forums somewhere (because there is no support for running gb and jb on the phone because of non kernel support for the both),
2. After you get your phone booting up root it with siyah kerneb by flashing it frue odin like flashing the stock rom,
3. Now install jb (i recomend you the jelly bam version by igio, awesome rom )
4. Now that done if you want to go back to gb you have to install gb stock rom yust like in odin.
5. Root the gb and install cwm kernel and you can get back to your rom.
JellyBam http://forum.xda-developers.com/showthread.php?t=1903162
So to your question NO you cant as i said the kernel does not support gb and ics/jb on the same device...

What a load of crap that other guy said.Just make a nand backup of your GB setup,then flash the JB rom/kernel.You can backup that if you want/or dont(if you dont youll lose option to restore JB).
I can alternate between GB/JB by just restoring nands anytime I want.

Nandroid Backup or nand backup - a Nandroid backup is essentially a complete snapshot of your phones operating system—application data, and all—that be restored via recovery. It’s always a good idea to keep a backup of a nice stable setup just in case of emergency so that u can restore the same using CWM recovery
so that it saves u all that time u need for dwnld'ng a firmware and flashing the same and setting up ur phone to its previous wrk'ng state, with all ur apps and its data
PS- u can use that CWM app (the App after rooting) to perform those actions
Eg.Im using XWKI4 with siyah v2.6.14 kernel.I go into cwm and make a nand backup.
I can then download say vanilla rootbox by bajee,and once everythings set up ok I then go into cwm again and make a nand of that.
2 minutes later I go into cwm and restore my GB backup and Im back on GB.
For your other question,I think the siyah GB kernel has cwm as an "app",but I dont think the vanilla rootbox kernel did.I changed the kernel to dorimanx but I went straight back to GB.
Anyway,I just use the 3 button combo to get into cwm.

Correct me if im wrong..
So as long as i already created a GB backup in my int sd card, & after which i flash a JB rom. If i want to switch back to GB, i just reboot to Recovery mode with up-home-power buttons & from there i can restore my previous GB (backup in int sd card). Is it correct?
In addition, regarding kernel..
I explored some rom & their steps of flashing, none mention about flashing kernel?
I know kernel is sth connecting hardware with OS (right?), then why flashing kernel is not included in the rom flashing steps? Is flashing another kernel necessary?
When flashing a kernel, must i connect to pc to do so, or simply copy kernel file into int sd card & flash it (using recovery mode?)?
Thanks for ur patience!
1.yeah,thats what I said
2.the roms come with the kernel,and some come with aroma installer which lets you choose various combinations eg. kernel/apps/launchers whilst you are installing the rom.
Anyway you can chop and change compatible kernels whenever you like.....same with modems.
People try different kernels for performance/battery life so its not compulsory.
You can use odin/mobile odin or cwm for flashing.
And its best to backup your efs folder when your rooted also and keep a copy on your pc.

IMEI.
just download hkctool off play store and use that.
Used 'CWM app' to backup into ext sd card; restore also using 'CWM app' w/o any issues.
However, when i reboot to recovery mode, i cannot restore as indicating 'file not found'.
My question is: whether the backup file must be inside int sd card instead of ext sd card?
Thanks!
It doesnt matter where it is.The restore option in cwm looks at your external card,and the other restore options further down look at your internal card.

It might be in your internal and the cwm is looking for it in external or in other direction that is looking in external and the backup is in internal you can look wit the explorer or something. Look for the clockworksmod folder or something. Mine is in the external sdcard. Try to move whole folder in internal maybe.

[Q] Nandroid backup of Gingerbread on Samsung Galaxy Proclaim

Hey Everyone. Sorry if I posted in the wrong spot, but I've watched the "noob" video, and I couldn't find anything about my phone on here. So, I've become interested in custom roms, and I'm thinking about learning how to make some. I currently own a Galaxy Proclaim, and I havent been able to create a nandroid backup. I've successfully set up the adb on my Lubuntu Netbook, and I ran adb backup, and apparently that only works for ICS. So, that leaves me with a few questions. How do I make a nandroid backup of gingerbread? What does ROM Manager, from googleplay, back up? And Is there a way I could make a backup manually? I know how to backup the files on my system, but how would I backup the bootloader and everything else? Sorry about all the questions, I'm just curious and determined to make a custom ICS rom, or compile a ROM from source, but I'm afraid to try anything because I don't want to brick my phone.
Buddy do it via cwm.download compatible cwm for ur cell to sd card to root and go stock recovery m0d install zip from sd card and select cwm then select backup restore and in that option just select backup and wait until its done.u need root for flashing cwm in recovery.

Clockwork Manager doesn't support my phone. The phones model number is SCH-S720C. I've tried other backup apps and they back up my apps/media just fine, but I need a full nandroid backup in case I mess up the boot loader or flash the wrong .pit file. I'm not taking any huge risks this time since I bricked my last one. Is there anyway I could make a backup manually? I currently run Lubuntu 12.10, and I've compiled adb and it works right on my computer.

[Q] Dual Boot - ROM backup

I'm using GoogyMax (have also used Siyah) and running Purelook HD Rom along with Slimbean as 2nd ROM. Right now I have my phone exactly how I like it but I also like trying new versions. It gets confusing doing Nandroid in each ROM and running backups from both using TB (Titanium) or MBR (My Backup Root) and recently I managed to stuff things up and had to rebuild from scratch.
Is there a way to do a Nandroid and get the entire package backed up? I am presuming in Slimbean backup I get only that ROM (it's around 1.1GB) and the same for Purelook (it's around 2.17GB) It would be good if I could simply boot to recovery and run one Restore and be back to my full setup.
Or am I mistaken in the idea Purelook, based on 4.1.2 stock, would be 2 times the size of Slimbean?
Shouldn't nandroid in CWM backup both Roms as the second is a kind of subset of the first regarding folder structure?

Shouldn't nandroid in CWM backup both Roms as the second is a kind of subset of the first regarding folder structure?

No, 2nd ROM is:
/sdcard/.secondrom
This is why it's best to use Siyah recovery to manage nandroid backups for 2nd ROM. However, since /sdcard/.secondrom should contain all the ROM stuff (including data) IIRC, shouldn't you just be able to rename that to /sdcard/.secondrom_OLD and reformat a new /sdcard/.secondrom?
Thanks for the replies.
I am unable to locate the /secondrom using ES File Explorer. Going to / and searching for 'secondrom' gives me no result. secondrom is deinitely there though - I just booted into it. Either it's a setting in ES that I need to change so I can see it (I'm using ES File in the 1st ROM) or I am not understanding how the folder set up works with dual boot. (or possibly, at all )
I guess, unless there is something more specific to find on here, I will have to backup everything then try a restore of each nandroid and see what it gives me.
Its .secondrom, meaning hidden file. Have you enabled hidden files?
On 4.1, /sdcard is /data/media but on 4.2, its /data/media/0 so you'll need to use root explorer permissions to browse and check /data/media if you're on 4.2 as it may appear "missing" as per link in my signature
