How to have "dualboot" + on "every" device,simple method!!! - Optimus L3, L5, L7 General

Just a info for have dualboot or maybe more roms on one device using backup+restore.
---
Whats needed:
1. A device with a unlocked bootloader and latest custom recovery.
2. Two or more other custom roms that can be flashed with recovery
3. A lil bigger sdcard class 10 is the best,because faster.
4. A brain
---
You dont need to mod or code hard stuff ,because its simple to do it without modding or something.
You need only a second or more customroms (normal, or not?).But it must have same baseband i, not tested with different basebands.
Now u do a nandroid backup from your current rom and than wipe data/factory reset and flash new rom and do your settings.
When all is done do a nandroid backup from this rom too.When u are addicted like me you can flash three or more roms with same method.
Now you have the option to switch between two or more backups,because you have two or more backups that u can restore in your sd,easy...not.
That goes with 100000 roms the only limitation is your external sdcard space.

How to do a fresh install of ROM on rooted note

Hello i successfully rooted my galaxy note and overclocked it im running darkynote rom but want to change to a new, But firstly i want to do a fresh install delete everything apart from the kernal and root, Do i simply just go into
Privacy, Factory data reset ?
First of all, you want to do a backup of your existing system and data in case something goes wrong. The way to do this is
1. reboot into CWM Recovery
2. choose Backup and Restore option
3. Backup
and CWMR will backup everything. Restoring is just as easy (if something goes pearshape with your new install).
Usual steps when flashing new Roms are
1. reboot into CWM Recovery
2. wipe cache (2 times)
3. advanced/wipe Davlik cache (2 times)
4. factory reset (2 times)
5. install zip from sd card (this is your new Rom)
However, bear in mind that some Roms have different flashing procedures, so you'd do well to follow closely flashing instructions in their respective threads. Those can be usually found in 2nd or 3rd post.
Hope this helps.

Refer this lucid guide for all your need for flashing a new ROM on your rooted Gnote: http://forum.xda-developers.com/showthread.php?t=1424997
I hope u are aware with every custom rom flash, you change your binary counters and that this will hamper your warranty claims, in case of needful. Nevertheless, its always useful to be enterprising... so good luck!!

This tutorial is for restoring nandroid backups

Hi Guys,
Im made this tutorial based on my personal experience, what pain i had to suffer for restoring my stock GB 2.3.4 nandroid backup, after messing up with CM7 and nvflash, i have consolidated all the thread in 1, i had tryed to make it simple to understand.
This tutorial is for restoring nandroid backups if u got in trouble while playing with custom roms and u want to go back to stock roms.
"Always make a nandroid backup of ur stock rom, before playing with custom roms"
Note :- Stock roms are based on EXT3 and Custom roms EXT4, here u get stuck when u try to restore nandroid of stock EXT3 to EXT4 partition.
1. Root ur stock roms with superoneclick. http://forum.xda-developers.com/showthread.php?t=953182
2. Install CWM recovery http://forum.xda-developers.com/showthread.php?t=953182 , or install Rom manager from Market, and install CWM from it.
3. Make a nandroid backup.
4. Install custom roms as ur likes and wish play with it, custom roms coverts ur partition form EXT3 to EXT4.
5. To convert back EXT4 to EXt3, use this link. http://forum.xda-developers.com/showthread.php?t=1021549
6. If u forgot to convert partition and try to restore nandroid u will get into boot loop LG screen stuck.
7. In boot loop u have only 1 option thats NVflash use this link http://forum.xda-developers.com/showthread.php?t=1007825.
8. After sucessfull nvflash stock, repeat step 1 and 2 as mentioned above.
9. After completing step 8, copy ur nandroid backup to ur SD card, now ur ready to restore ur stock nandroid backup boot into recovery restore.
Thanks for reading this
I think boot loop doesnt inevitably mean you have to nflash. For example, when having boot loop caused by installing EXT 3 rom to EXT4 partition, it is sufficient to pull battery and go to recovery(holding power plus vol down), then use back2ext3 etc.
Also, i have many bootloops, but never nflashed before.
Good turorial for beginners anyway.

[Q] CWM Restore after flashing custom ROM

Hi there,
I have a rooted N7000 running original Android v 2.3.6
I want to flash (test) it with a custom ROM.
I made a full backup of my current system (via CWM backup)
Now, when I flash a (new Android 4) custom ROM, will it then be possible to restore the old v2.3.6 image that I made, using CWM?
Other question: Do I need to take care of what type Kernal version I have
I have 2.6.35.7-N7000XXKKA-CL726566
Baseband-version is N7000XXkk5
Thanks for your reply.

nothing to worry about, that is what backup is intended to do.
the only thing you have to watch that you're on safe kernel like philZ when wiping data in stock ics or jb (read sticky threads)
example: if you are on philz kernel and runing ics or jb, when you restore your backup of gb, you restore your gb kernel, system, data etc, just like backing home

OK, Thanks for the reply. So if I understand correctly:
1. I make a backup of my current ROM (Image via CWM) and put it in a safe place.
2. I can flash any custom ROM, and test/play with them.
3. Afterwards I can put back my old ROM again via CWM restore.
4. Reboot, and I'm back in the old state.
Is this right?
Can I flash ROMs by using CWM also (using zip files) or do I need to flash, using Odin?
I actually do not understand your remark about philZ, can you explain a bit more about what that means.
Thanks for your help so far

Since you are going to try custom rom, you need not to worry about emmc brickbug, since they will be using a safe kernel..but double check before flashing...so, if you are on Stock ICS kernel, you should NOT wipe/factory reset..if you do, you will brick your phone..you can just go through couple of sticky threads to know abt emmc brickbug, if you are not aware of that..whatever the steps you have mentioned above are correct..but when you flash a custom rom, follow the instructions mentioned in the Custom rom OP...

1. Yes, copy your /clockworkmod to your pc (just for double safety) dont cut it or move it, you need it on your internal sd card always, if you wanted to restore it again... and dont rename it (you will end up with message md5 missmatch!)
2. of course
3. Every new custom kernel like Philz kernel ( for ICS TW and JB TW) http://forum.xda-developers.com/showthread.php?t=1901191
or hydracore (not working on TW JB, but works on all other) http://forum.xda-developers.com/showthread.php?t=1749863
have built in CWM 6.x.x.x , You can recognize them by the gray background in CWM recovery. (there is no need to install independet CWM or something else, like you do on your stock GB kernel)
They are built in almost every custom rom, and these kernel are safe for wipe.
3.1 . So if you flashed new custom TW ics or jb, and after playing with them, you want back to your nandroid backup, just go boot in recovery (now you see a grey background CWM6) do all the wipes (in my experience the best way is: (advanced > wipe dalvik cache, go back > wipe cache, then wipe/data factory reset, then go into mounts and storage > format cache,system,data and preload , dont format emmc and sd card. go back into backup/restore > restore from (internal sd card or some other place depends on where you place your backup)
4. of course, when youo see a message backup complete, reboot it

Where to start ?

Spent quite some time searching through the forum but I'd still like a few pointers on where to start particularly (in which order).
Like;
1) Root
2) CWM
3) ROM Manager
4) SuperUser
5) Odin
6) Data wipe
7) Binary count reset
8) Recovery Manager
9) Custom ROMS
(EVEN THOUGH I'VE NUMBERED THEM, IT'S NOT LIKE I KNOW THE ORDER, JUST IN CASE YOU'RE WONDERING)
So here are my main questions:
1) In which order do I install them ?
2) Is there any relationship between them? (i.e. I thought ROM Manager let you install CWM and with CWM you can get to Recovery manager or something...)
3) Do I need the Recovery manager for recovery or for installation of custom ROMS?
4) What is the point of getting custom ROMS when I get root ?
Phone: GT-I8190
Android: 4.1.1
Baseband/Build: I8190XXALJL
Thanks in advance, and apologies for asking same question if there is a thread around here about it.
I'd prefer ppl to explain rather than referring to other threads as that got me a little confused before. (you may still refer if that thread is clear enough)
Ok. The order is
1- Root (superuser comes with it)
2- CWM
3-see the right rom for u
4- wipe data, cache, and dalvic in advanced, to flash rom
5-reset counter when u flash anthing in odin u will have a yello triangle to remove u have to reset counter ( does not effect the phone

Could u explain 3 a bit more ?
Also is there any relationship between CWM, ROM manager, custom ROMS and Recovery Manager ?
Go to development forum, pick one of the pre rooted firmwares and flash via odin. Then install rommanager app from tbe play store and flash cwm recovery. Don't worry about binary count coz triangle away app works on our phone. If you want to wipe the phone reboot to recovery and wipe data. To boot into recovery use the quick boot app from play store.

...and most important.. Don't forget to make a full nandroid backup in recovery before you start to apply mods and other things
Might come in handy if the phone fails to boot!
Should note that after custom rom you can't get access software update through kies air. At least I can't :-\

So if I understand this the right way; CWM recovery has custom ROMS or am I getting the wrong idea ? - Why do I need it ?
(It's just that I've been a little confused because of the mass information available on XDA, so bear with me if I'm a bit annoying

Which would you prefer; Nandroid or Titanium ?
Do I need "busybox" for anything ?
Do I need Kies to connect my phone to PC btw ?
Another question: There are two recovery images on the official site of CWM, do we need to choose the normal one or the touch and what about the ROMS, do I need to install those seperately ?

With cwm or any other custom recovery you will be able to install zip files with mods, tweaks, roms, and so on. Simply put, non-samsung-signed-things + other functions as well.
You wont find many custom roms for s3mini yet wich it to be flashed through cwm. For now i think theres only BenzRom but I guess more will come
Nandroid or Titanium ? BOTH!
Nandroid for restore if something goes really bad, and remember to make sure you have a backup before you apply changes or mods. If you dont like it you can easily go back to previous state without flashing new firmware and have to install all your apps from scratch.
You will be just where you were at the time the nandroid was made.
Titanium backup to backup your apps and appdata. When installing new rom you can simply restore all your apps and appdata without downloading everything again. Do not restore systemdata. It often leads to alot of trouble.
Just make sure you save all your backups on your external sd, so it won't get wiped by mistake.
Busybox is needed if you want more than just root so go ahead and install.

Last couple of questions for now (apologies ) ;
1)Do I need Kies to connect my phone to PC btw, cuz I read something about USB debugging mode to be turned on and ADB...
2)There are two recovery images on the official site of CWM, do we need to choose the normal one or the touch and what about the ROMS, do I need to install those seperately ?
3)So every time we flash another ROM it has a chance to brick or are we safe if we made a backup beforehand ?
4)What format should I format my card to ? - FAT32, NTFS, ext4 or ...?
5)Does data wipe erase all data on phone or phone and sd card ?
6)Given both CWM and Odin flash what would be more recommended ?

No worries. Better be safe than sorry
1. No, you dont need keis unless you want to look for official updates.
For filetransfer I use Airdroid or box/dropdox/4shared. Official updates will be available to download anyway
Adb (Android Debug Bridge) is just a terminal. I won't go in to details here but you will find lots of threads on how to install and use it if you search xda.
2. They both do the same thing, but in touch-version you make your choices on touch screen while the other one is managed with phones physical buttons. I prefer the latest.
Roms for cwm are packed as .zip & are downloaded separately. As I said before there isn't much to chose from for our device yet.
3. Everything done after root is a risk. Even root can be dangerous if it's not done right.
Usually if something goes wrong it will just lead to a softbrick wich can be fixed in download mode or recovery.
Once rooted, make sure you do that cwm-backup to keep on your external sd. It's also a good idea to keep an odin flashable firmware on your computer, just to be sure.
4. Go for fat32. It can be changed later if you want to explore link2sd, sd-swap etc..
5. Factory reset will wipe all internal, but not your external sd.
6. cwm makes it possible to flash custom roms while odin can't. You need odin to flash official samsung firmware, but cwm to flash custom roms, mods, and so on. Can't really compare those two with each other, as they are used for different things.
:good:
Dated, but still very relevant.

What should I do for wired transfers only, I mean.
Do I need to search for the phone specific driver for pc at Official Samsung site or is there no driver ?
Any other things I need to turn on except USB debugging mode when wired ?

[Q] I need some help to get back to Ultimate XXLSZ

I was using Ultimate ROM XXLSZ_JB_4.1.2_v5.2 without any problems apart from poor battery performance.
However, I attempted to install Rocket ROM-V1-XXLSZ and have now got myself into trouble.
I followed the instructions to flash the latest XXLSZ-OXA cwm kernel and then flashed the Rocket ROM. It worked ok but I would like to return to the Ultimate ROM and kernel I had before.
I have a pevious full Nandroid backup of the phone (made with ROM Manager Premium) of the Ultimate ROM and the PhilZ kernel it came with but cannot restore it. I get the error "MD5 Mismatch" and the restore aborts.
Even if I reflash the original Ultimate ROM with all the usual wipes, the XXLSZ-OXA cwm kernel is still there and I still can't restore from the Nandroid backup. I tried re-flashing PhilZ 3.1 kernel separately and then the Ultimate ROM file but this didn't work either. The kernel is still the same.
Can anyone tell me how to either
1. completely wipe the phone so I can install Ultimate ROM AND the built-in PhilZ 3.1 kernel.
OR
2. get the phone to the point where I can restore from my Nandroid backup which I assume will restore the earlier version of the ROM at the same time.
I hope I've explained the situation clearly enough.
Thanks in advance.
Trevor
Install a cm kernel then wipe your phone then install a fresh ultimate rom and later on advance restore the data

You don't want to restore your nandroid. It is a bad backup.
In philz recovery go to mounts and storage. Format system data preload cache. Them go to advanced from main page and wipe dalvik
Flash ROM. Guaranteed to work.

Thanks. I know I can flash the ROM again but I was hoping to learn why the Nandroid backup no longer works.
Since posting, I gave up trying to restore the Nandroid backup, did all the usual wipes, re-flashed the Ultimate ROM and re-installed all my apps from scratch so my phone is more or less back to normal (Incidentally, I notice that no matter how many times I do this, all my music and photos are still there even though they're stored on the internal sd card. Dunno why).
Most of the ROMs I've tried have the kernel built in so all I needed to do was do the usual wipes and then flash. If I didn't like the ROM, I just wiped again and restored the Nandroid backup using CWM (Vol Up + Menu + Power) and the phone was back to its previous state.
The only thing I did different this time, as per the Rocket ROM instructions, was flash a kernel first. I may have done something wrong with that step or messed it up somehow. Even when I flashed an earlier version of the PhilZ kernel, the restore still didn't work. I've still a lot to learn about ROMs and Kernels, I guess.
As I said, I have successfully restored from Nandroid backups many times before this without any problem after experimenting with different custom ROMs. Can I ask you why Nandroid is a bad backup? Is it a problem with ROM Manager?
(One problem I've always had with ROM Manager is that if I choose to write the backup to the external sd card, it falls over with error messages. If I choose the option to backup to the internal card, it works but writes the BACKUP TO THE EXT CARD ANYWAY! I cannot get a reply from the dev about this).
Is there a better, more reliable backup method you'd recommend that does the same thing as the Nandroid?
I notice that different ROM managers use different CWM Recovery versions ie ROM Manager Reboot Recovery = 6.0.1.2, ROM Toolbox Rebooter = CWM 6.0.2.8 (same as Vol Up + Menu + Power). Could that be part of the problem?
Sorry for the long winded post.
