Hi my phone has already been rooted and loaded with a rom as far as i know. someone did it for me before but i completly forget how he did it and dont know where to start. Was reading the guides but i dont quite understand how to do it from when i already have one loaded in. Any chance someone can lead me to the right direction. Also have Cyanogenmod 7 not sure if that makes a difference and clockworkmod recovery v3.0.0.5
Flash latest recovery through rom manager, download rom you want, verify md5 sum, transfer onto sd card if not already there. Then this it's what I do-reboot into recovery, use trackpad to scroll and select items, perform a backup of current rom (nandroid), factory reset, wipe cache, wipe dalvik cache, format system (very important), choose install zip, scroll through your sd card files until you find the zip, select it and let it do it's thing. Once done, reboot phone, let boot and leave alone for 10 minutes, reboot into recovery again, fix permissions, reboot phone and let sit for 5 minutes (should load a lot faster), then set up phone how you want. Use apps from the play store to back up app data, text messages, etc. just don't bother backing up system apps, can cause issues. Download any apps you want directly from play store (under my apps) before restoring data to them. Make sure you don't wipe sd card unless you have it backed up on a computer and are willing to transfer everything over in recovery...it all sounds complicated but after you do it a couple times, it doesn't take very long. Main thing is to ALWAYS make a back up before flashing anything (rom, kernel, mod, etc.) To flash a kernel, you just need to wipe cache and dalvik cache only and fix permissions.

I'll just put this out there for other noobs using twrp. I've never done a nandroid backup before, and I'm currently running twrp v2.6.3.2. When I select backup, it directs me to select which partitions, with boot, system & data already checked. Do I need to check any of the other options (Recovery, Cache, EFS)? TIA.

most important is the EFS one, somewhere mentioned it contains your IMEI etc. Backup it, and copy it for safe keeping. Everything else you should be able to recover, but EFS if lost might lead you to a non-usable phone.
Cache not needed.
Recovery well depends, but its just 8-11MB more I would check it as well.
Actually you can back it up all.
The most space will take the SYSTEM and DATA anyways, the rest is few MB's. Let's say SYSTEM is your ROM (system apps etc), and DATA is your config and installed apps. (Not entirely true if you do some modifications but these 2 partitions you need to restore the backup as you had it)
Boot is the kernel. Which might be needed by the specific System if you go custom, again only some MB's.
Just remember that you can even choose what you will recover. So when you change your recovery, kernel etc and you go for restore of some older backup, careful of compatibility in between ROM and KERNEL for example
Awesome thanks for the quick informative info. I figured it wouldn't hurt to just backup everything, but I thought I'd ask just in case I missed something.
I have a custom ROM (PA 3.99) on my phone. I am meeting a guy tonight to sell it, and my new phone comes tomorrow. So I need the phone up until I meet the guy, so I will wipe after he agrees to buy. What all do I wipe to keep it working, but safely remove all my settings/pics/etc...? I'm on TWRP recovery.

Backup (apps&data), all of your pictures and videos, and anything you wish to keep to your computer. Download the factory image of KitKat or whatever you want to put on the phone, do a full wipe and flash.

Advanced Wipe partitions list: Dalvik, System, Data, Internal Storage, Cache, usb-otg. Do I select them all to wipe?
Also, the Format Data menu says it wipes backups, pics/vids, media, and encryption. Do I do that too or is the above sufficient?
Wipe everything but system and otg
If you wipe system then there is no rom on the phone. Don't have a otg device plugged in so that's useless

OK thanks, that was what I was wondering - how I wipe everything but keep the rom zip to flash to. So doing it your way, after the wipe, I reboot to a new phone (running PA 3.99) with no flashing needed?
Doing it that way will be leave a clean install of that rom. It won't change the kernel though if you flashed a different one over the one that came with the ROM.
If you wanted that back you would just dirty flash that same rom overtop of it.
In a nutshell there are a bunch of partitions on the devices. I won't go over ALL but the main ones we use.
/ system is the ROM
/boot is mainly the kernel.
Wiping all the rest leaves it clean. All your data and media goes on those partitions / mount points /data / internal storage or emulated / whatever the heck it is.
Basically yeah wipe everything but system ( and boot if your recovery has that option)
Hello, i want to try a different rom out and im wondering what things do i need to back up in twrp just in case something goes wrong or i want to go back. Also if i go back i would like everything to be right as i left off before flashing a new rom. My backup options are Boot, System, System image, Vendor, Vendor Image, Data, Chache, Recovery, EFS

By default, you have to backup Boot, System and Data

Don't you have to disable all security passwords like pattern lock and fingerprints before making a nandroid or it won't work when you restore? I read that in the How to thread for the 6P. Wondering if this is true or not.

Thank you! Im going to try flashing the BeanStalk 6.02 rom on my 6p tomorrow! Would it possible to restore data on a new rom coming from your old rom? For example: My Nexus 6p is running chroma rom right now, if i back up the data partition can i restore that partition onto my new rom ( BeanStalk 6.02)?

Yes that would be true, you would have to disable any type of lockscreen security because it wont let you unlock your phone after restoring.

Thats not even remotely a clean wipe and would cause nothing but issues.
I would highly recommend not doing that.

Noooooooo. When flashing a different ROM you need to clean flash (wipe system, data, cache, dalvik cache).

Which partitions do you backup and restore?
I don't feel the original question has been fully answered and explained.
The usual answer is: boot, system, data.
In the guide, section 4 that Heisenberg links however, vendor is added to the mix.
Remaining questions:
- Is vendor needed for usual backup together with boot, system and data. If so, why? What does it contain?
- What about the remaining partitions? Vendor image, system image. What do they contain and why do we not need them backed up?
---------- Post added at 01:40 PM ---------- Previous post was at 01:39 PM ----------
Also, yes you can still get back into a backup with fingerprint lock still active. See this post:

Boot, system and data are fine just as it's always been. I've already done this and restored with no issues. Even with lock screen security. All you do is use file manager in twrp to delete "data/system/locksettings.db". If you know what you are flashing is going to actually write to a partition other than boot or system then yeah, back those up too. Suppose it wouldn't hurt to grab backups of each partition individually and store them on your pc to be on the safe side.

The only issue with not backing up and restoring the vendor partition, and the reason I include that in my guide, is if you have themes applied they will survive through the wipe and be carried onto the restore/flash, potentially causing compatibility issues and a failure to boot or a wonky/unusable system after boot.

Oh so that's the reason! Well thanks, then I know what to do! I'll include the vendor partition then just for safety. I already have a complete backup of all partitions except recovery and cache too so I'll just keep that safe somewhere just in case.
Thanks for the replies!

I backup/restore my boot, data and system partitions to data/media (SDCard)
So what are other options such as system image?
Is it necessary to back it up? I just backed up the default ones

System.img is just that. An exact image copy of the system image in one chunk. So you would end up with IMG files. It's not necessary to choose the IMG options. Default options for boot, system and data is a complete backup.
Hi,
after few soft-bricks and hours, i was able to transform my stock A2017 B16 to stock A2017U B25 and everything is working.
now the device is B25, android 7.1.1 + TWRP 3.1.1-0 and i want to make full backup as i know the need it if something goes wrong (and it probably will )
in the back up options i see the following:
Boot (64MB)
Recovery (64MB)
System (4740MB)
System Image (6144MB)
Data (excl. storage) (4001MB)
Cach (27MB)
Modem (NON-HLOS) (95MB)
Bluetooth (BTFM) (1MB)
EFS (6MB)
for now, i did backup of all of them but didn't tried to restore because i saw somewhere that i can get you brick .
can you help me understand what to backup for *complete backup* which one i can use in emergency recovery cases?
Boot - This is your bootloader. I usually back this up.
Recovery - This is twrp, you could back it up by itself once, but it isn't necessary.
System - This is your rom and stuff. This is the main thing to backup/restore if you want to keep the current ROM you are on.
System Image - I'm not positive on this, but I think its a full image of the whole system with everything.
Data (excl. storage) (4001MB) - This is all of your personal data, apps settings, call logs, etc.
Cach - no point in backing this up
Modem (NON-HLOS) - I don't back this up either as you can always flash the newest modem files
Bluetooth (BTFM) - bluetooth settings/devices I think, probably don't need to back up.
EFS - Do one backup of this and keep it forever. If you ever wipe or mess the EFS up you are in trouble.
Don't count on all that 100% as I'm not a dev, but I've been doing this for years. Besides the one time backups I mentioned, I routinely just backup the boot, system and data and have never had any problems restoring.
If you are brave and installing a rom that runs on a similar base, sometimes you can backup only the data, and flash the new rom, then restore just the data and have all your settings and apps stuff back.
Hopefully that helps.
Boot, System, Data- just like the person above me.
That's all you really need to do. Sometimes I'll even do things like wipe system only if I'm having problems with the ROM, Gapps, or some random mod, and reinstall the ROM & Gapps to bring it back to a clean slate. Say, if I tried out A.R.I.S.E. sound mod but it was acting goofy and I wanted to make sure I removed all of its remnants.
Recovery is unnecessary I'd think.
EFS - I guess backup once.
Why not backup everything? It doesn't take up much space. System image seems to be the only one I'd leave out. I still back it up anyway.

You're mostly correct except boot, which is the kernel and not the bootloader, and system image is this as mention in an old TWRP changelog:
The Team Win Recovery Project has released version 2.8.7.0 of its custom recovery, known simply as TWRP. This update brings a system read-only option that's intended to help you make a pure backup of your system image that you can later flash to receive over-the-air updates after having rooted or ROMed your device.
Cheers.
@mb0 Basic backup is system data and boot to have a working device, but I'd backup everything at least once just to be on the safe side.
The "backup all" solution sound nice to me??
At least one full backup and i keep it in safe place(es).
Let's try the restore function and hope not to be surprised
Hehe, good luck mate!
I'm back to update...
Full backup (except 'cache') --> reboot to recovery --> normal 'wipe' --> reboot (to make sure that it wiped) --> reboot to recovery --> restore everything (except 'cache') -->reboot --> ITS ALL GOOD :good:
