[Q] How to do a flashable zip from a current running rom ? - AT&T Samsung Galaxy S II SGH-I777

Well It's possible/safe to make a flashable zip of my running rom, exactly "full image" of my current one.?
So lets say my Rom A already have all the appz/modz,librarys added, and it's themed exactly as I like.. But then next week I want to run Rom B, again customized (kernel, modem,etc) to what best work for me and likes, then I want to try Rom C.. And then I want to run Rom B or A, or whatever.
So instead of flashing a completely new Rom, and start again with my mods, just wipe everything and flash my "customRom.zip on CWM
So how to make it ?
searching I found that doing a nandroid backup and trying to do a restore from that backup, must have the rom flashed first and then you can do the restore. Is that how it will work if I want to change roms ? Or is there any other way ??
Thanks.

No, a nandroid backup is basically a complete backup of your system. Configurations and all. I'm not 100% sure if a cache and dalvik wipe is needed between restores. But each backup should put your system back to exactly the way it was when you did the backup. Anyone pop in and correct me if I'm wrong.

You dont need to do that. In CWM just do a back up, it will back up everything. All of your settings, apps, customizations etc... it will basically back up everything like a mirror image. Then you wipe /system /data /cache and flash your new rom. Once you get it set up the way you like it, back that up, then wipe again, flash rom c, set that up and do another back up. You will now have 3 backups of 3 roms with however you set those roms up when you backed them up. for example: I have a back up of the Stock Rom, then a back of of ICScrewed, then one for Miui. Whenever I want to switch to one of those 3 I just go into recovery and restore whichever one I want to run. When you do a restore you dont need to do a wipe because recovery will wipe everything before it restores
but say if you flash rom A, back it up then flash rom B then decide to go back to rom A and while you are on rom A you make more changes to it install more apps, mods you will have to re back up Rom A otherwise you will lose those changes when you go to rom B or C and come back to A.

I don't wipe cache or dalvik cache when restoring a backup. I don't think it matters.

Awesome thanks.. Just a last questions.
I guess it doesn't matter if I rename the file created right ? Or must remain in the datehour format ?

You can rename the folder and it will still work fine.

I did hear though that it doesn't like spaces in the folder name. For example it won't like miui 2-15-12 so you would just name it miui_2-15-12

Flashing stock ROM and the going back to Cyanogen

Hello, I always find the people on this corner of xda very helpful. As usual, I think I know what I'm doing, but I'd like to check that I am proceeding in the right direction.
I've been using Mik's Cyanogen ROMs on my Optimus One. That's going well. But I need to SIM unlock my phone and I need to go back to a stock ROM to input the codes (please let me know if this is incorrect).
Before installing Mik's ROM, I performed a Nand backup. I have boot, cache, data, recovery and system img files. I think I can flash these through recovery and I should be back to stock.
Do I lose my apps and settings by doing this? Do I need to clear any caches?
What about returning to Cyanogen after I unlock my phone... Do I have to root my phone again or will I still be able to flash using recovery?
Using Clockwork, I just backed up my current ROM. I assume I will be able to restore from this later.
Is there anything else I should be aware of?
Thanks for answering my questions / clearing up my confusion.

this is correct

Do I lose my apps and settings by doing this? Do I need to clear any caches?
to revert back to stock, you must wipe data/factory reset, cache, and dalvik cache. you will lose your settings. as for your apps, you can back them up with titanium backup and restore them after you have restored your backup.
What about returning to Cyanogen after I unlock my phone... Do I have to root my phone again or will I still be able to flash using recovery?
when you restore your backup of the stock rom, you will still have root. i dont think unlocking your phone will cause you to lose root. your root access and custom recovery will still be intact
Using Clockwork, I just backed up my current ROM. I assume I will be able to restore from this later.
yes this is true
Is there anything else I should be aware of?
just to be on the safe side, please list the steps you are going to follow
Thanks for answering my questions / clearing up my confusion.
Thanks for the quick answer...
I on my sd card, I have a /clockwork directory with two subdirs. One is my original backup that I made before first installing Cyanogen. The other is the one I just made. Both contain boot, cache, data, recovery and system img files. The difference is that with my new backup the image files have an extra yaffs2 suffix: cache.img (stock) but cache.yaffs2.img (Cyanogen). Any problem here?
1. boot into recovery
2. restore stock from my sdcard using nandroid and wipe caches as you indicated
3. reboot, enter unlock code
4. reboot into recovery
5. restore current ROM from my sdcard using nandroid and again wipe the same caches
6. reinstall / restore apps (I'm not using Titanium, instead I backed up the list of installed apps)
Will I need to find and reinstall the GoogleApps (Market, etc) or will they come with the backup of my current ROM?
Pretty simple really. This make sense?

there might be a problem. what clockworkmod version did you use to make the backup of the stock rom? if i remember correctly, using cwm 3.x.x.x backs up a certain way (and also does not have the yaffs2 suffix) and using cwm 5.x.x.x backs up a different way (with the yaffs2 suffix) so backups may not be "inter"compatible (more info on that here). however, you can just flash back cwm 3.x.x.x right now (you can do it using rom manager), restore your stock rom backup, do the following steps, flash back cwm 5.x.x.x, then restore your backup
1. boot into recovery
2. restore stock from my sdcard using nandroid and wipe caches as you indicated (i recommend wipe first then restore)
3. reboot, enter unlock code
4. reboot into recovery
5. restore current ROM from my sdcard using nandroid and again wipe the same caches
(same here again, wipe first then restore)
6. reinstall / restore apps (I'm not using Titanium, instead I backed up the list of installed apps)
Will I need to find and reinstall the GoogleApps (Market, etc) or will they come with the backup of my current ROM?
i think you will have to flash gapps again
Pretty simple really. This make sense?
looks good (how sure am i? id say 80-90%. it definitely makes sense, but i have never done this before)
Good good. It's getting late so I'll tackle this tomorrow. Thanks for the detailed help... I'm glad I asked before going at it.

I followed your instructions (I downgraded Clockwork before starting) and the 10-20% chance of you being wrong came true... but in a good way
Restoring from the backup brings everything back: apps, settings, contacts, SMSs etc. So it was actually even easier than you suggested since I didn't have to use my backups at all.
Thanks again for the tips!

Yes... when I was back in stock I could access the unlock menu by entering 2945*#500# on my keypad. The SIM unlock code that I have worked fine. I haven't actually tested with another SIM card but the phone claimed to have been unlocked, so I should be good to go.

It backs up everything, it will basically cryogenically freeze your version of Android as it is for later use. So yeah, if you don't like ROM x you restore ROM y from nandroid

2. To remove root you need flash stock firmware (I think)

1. nandroid backup is backup everything
2. yes you can, if don't want that custom rom, just restore the nandroid backup you make
A NANDroid backup does not include the EFS, however, and you will want to back up that up in case your IMEI ends up getting lost. (Grab kTool from the Play Store)
Also not included in a NANDroid backup is the modem and kernel. These don't require you to back them up yourselves, as you can find stock kernels on the Internet (and modified ones) as well as the modems, but it's worth noting that some unofficial ROMs do tend to flash these as a part of their install process

Music to my ears :thumbup::thumbup:
I use Nandroid backup as a method to save all my folder and apps layout ,
flash a new rom just format cache and system .
That gives me my layout plus the new rom works 99% of the time if upgrading to similar roms even moving from LF2 to LG8 .

Nandroid backups your system data cache and boot partition this means after restore you will get everything same as old times but you can't go back from aosp roms because they use mtd partition type but samsung roms use bml you have to flash stock rom from odin and then restore when you want to come back from aosp/cm based roms

I tried that but it didn't work for me probably my fault. I was a galaxy s (I9000) user and it was needed to flash every time stock odin rom before restoring to samsung roms and I guessed its the same on s3.

same here, but seems to be different with the s3, but there might be some problem between different versions of cwm recovery, that might be the problem..if you backed up on touch say..then tried restoring from 5.c.x.x?

What exactly does backup do.

A few days ago i put on Siyah neweset 5.0.1 kernel on my S2 and overclocked but my performance hasn't increased much so i'm gonna put Ressurection Remix ROM now but the first step on the guide says to format my phone and i hate loseing my things, is there anyway to keep my stuff on the new ROM D: ? I'm not sure what to do QQ i don't wanna screw this up, also i'm gonna make a few backups, cuz 1 isn't enough.
Over clocking doesn't increase performance per se.
You can use titanium backup to backup and restore your current apps. Use SMS backup+ for your texts and call lists.
Images, vids, music etc are unaffected by formatting via CWM.
Sent from my GT-I9100 using xda app-developers app
If you want to switch to another ROM, I guess it's best to backup all your apps via Titanium Backup. As far as I remember, the list displays white apps, red ones and green ones. The red ones are system apps and you should backup them since they differ from ROM to ROM. The white ones are apps which you have installed on your phone (via Google Play...). The green entries are things like "Messages" "Phone call history" and stuff like that.. I guess you can backup them too.
You won't loose your contacts as long as they are stored on your googlemail-account. So no need to safe them.
Then just backup your current ROM via ClockworkMod (I guess one backup is enough :b - If you want to be 100% sure try to backup and right after it finished try to restore the backup. If it works (in 99,9% of all cases) you can just flash your new ROM - if it didn't work try to backup+restore again. As soon as you've got a working backup (I guess the first backup will be OK), flash the new ROM and restore the needed apps via Titanium Backup again. (Just download Titanium Backup right after flashing RR and you will be able to restore every single app again).
More and more ROM devs advise not to restore apps via Titanium Backup, but it always worked fine for me
Hope I helped you,

Don't be ridiculous.
What about something simple like "How to backup data before installing new rom?"
In any case you should have searched google or XDA first as there is plenty of topics on how to flash roms without losing data or how to backup all your apps/appdata etc.

Anyway, i've been useing this rom since yesterday, it's awesome .. mostly
Some minor disadvantages, some things like Clock crash, won't update some things but that's normal.
My stock benchmark was 6800, now 6200 D:
Probably becouse the rom uses more RAM than stock.. Overall 8.7/10 <3
I'll keep testin.
EDIT: OH YEA! what were those "modems" it asked me when i was installing it?

Do you need to back up your stock ROM only once?

Hello,
I have a question. I backed up my stock rom before installing a custom rom. Now i want to install another rom, so this time do I also have to back up the rom or its already backed up as I did it once the first time? So now that if I want to move to a new rom, i just
Select Wipe Data/Factory Reset. Confirm on the next screen.
Select Wipe Cache. Confirm on the next screen.
Select Advanced and then select Wipe Dalvik Cache.
and I should be good to go? Any other steps?
Best wishes,
Marc
Nandroid makes a snapshot of your entire phone, so you can go back to the exact moment in time when you made it.
Unless you think you'll want to go back to the current custom ROM you are using then no, don't bother.
Factory reset won't wipe the system partition, you would be better off flashing Philz recovery which includes a wipe option for use between ROM's. It's a good idea to have the right modem & RIL for your country ready just in case your new ROM has the wrong modem included..
Make sure you have backed up the entire efs partition to your pc, dropbox etc.

Just copying the folder across in explorer won't save you if you need to restore, use Mike Skip's SG3 tool, the app from market or again Philz recovery to snapshot the entire partition. I'd advise having at least one version you can flash via odin.

It's not necessary, but you should always back up your ROM before flashing a new one.
It's a personal thing, but I only do so when I do a major leap, like from Sammy to cm or cm to Sammy or one of those to miui or something like that. Other wise I don't because I like having free space on my SD cards.

[Q] TWRP/Nandroid question

Hi, I'm not exactly new to XDA, however my Note is my first real Android phone. My question is this: If I want to make a backup of the entire phone, so that I can install a new ROM, then restore the phone to exactly the way it was before I installed said ROM, what do I need to select to back up in TWRP? I'm wanting to play with the Lolipop build for i717. I already have a good EFS backup stored separately just in case, so I need to select System, Data, and Boot, and this will save the kernel and the ROM contents, correct? ...and when I restore this backup it will be just like I left it, right?
Also, what do I need to select to Wipe to perform a 'Full Wipe' as is recommended before install?
Thanks for your time.

Use gimmeitorilltell's version of twrp as some specifics have not made it to official version. I've had great results using 2.8.0.0 though I believe some newer versions are working now as well. I backup android secure as well. Not sure if this is necessary, it was the default setting. Wipe is generally accepted as factory reset usually followed by going to advanced wipe and checking cache, and dalvik cache and wiping these again. Then install your new rom zip, gapps zip if required, wipe cache and dalvik cache and reboot. First boot will take a long time. Possibly as long as 5 minutes or more. Once booted let rom settle for at least 10 minutes before adjusting any settings. Good luck.
Edit: Your backed up rom system will restore everything back to the way it was if you desire to go back (installed apps and settings as well).
