Hey guys,
is it possible to backup my rom witg twrp to another but similar device? From z1c to z1c.
best, dj
Yes, this is possible and it works OK. I have done this many times.
Just make ABSOLUTELY SURE NOT TO restore the "TA partition" from one device to another! This partition contains device specific code. If you clone the TA to another device, it will not boot. The only way to recover would be if you have a TA backup of the messed device (and you will have to access its internals).
So to summarize: You can share ROM backups through multiple devices. Always do a full backup BEFORE you restore another one. Never restore TA partition from another device.
Thanks. Btw, if you share a micro sd card wirh multiple devices twrp generates device speccific folders. You can access only files from your "own" folder.

the wonder is my first android and I wanted to learn while before hacking on it ...
last night I did the root and installed ClockworkMod 6.0.1.2 to make a nandroid before flashing a ICS rom.
but I have come some doubts:
1) the nandroid with clockworkmod is done either on internal mem on external sd right? I tried with the internal memory and I did a backup of 17MB ... I have copied to the PC the folder ClockworkMod always 17MB: they seemed to me just a few for a nandroid backup... I did it again ... the same ...
2) then I added the external sd and I deleted the two previous backups from internal mem and redid the backup to external sd ... the process took about twenty minutes (slower then before), and in fact has made a backup of 790mb
3) I try to copy the backup on the PC with the phone attached but it don't work .... I removed the SD card and copied the folder on pc with win7: I did not copy some files because they are "too long" (???)... then I tried to copy it on a pc with ubuntu and makes the copy but when the transfer is finished tells me that the number of files copied is right but instead of 790mb is only 725mb: I need to trust this backup? ?? better to delete and redo everything? I do not want to flash something and do not have a working nandroid...
another question: when I flash a rom and do ALL wipe the sd external is reset? no I think, right? and to put on the contacts and messages and the settings I use those saved using kies or do I need to do a better titanium backup or save contacts synced to gmail?
sorry for the many questions but as I'm a true noob and before I do damage I want to have in mind what I was doing
I'm waiting your reply before flash a rom... thanks

First thing: Why do you need to copy the backup to your PC? I can certainly assure you that the backup is working fine. Just leave your SD card within your device upon backing up. And just leave it there. If you ever really wanted to copy the backup to your pc, well don't get the file size(s) wrong. They will certainly be different since the systems you are trying to copy the files to uses a different file system. So it's normal for them to have different file sizes. To add to that, the CWM uses generated MD5 to confirm that the backup (it's related files) are correct before it will restore a certain backup. If something is wrong or the backup got corrupted, CWM will not continue in restoring it.
Second: when you flash, your personal files in your sd card will remain intact. Flashing (may) be only wiping an SD-EXT if you created such partition in your card since apps uses this. So don't worry.
For most customized ROM, I'm afraid components regarding the communication of your device and Kies won't be integrated since devs prefer your system to be our of bloats as possible. So upon flashing a custom ROM, you might not be able to use Kies anymore. In flashing, internal data such as contacts, messages, APN, wifi(s), etc. will be erased as the system will be erased. So;
For your contacts: Sync it with Google or export them to our SD for later import.
For your APN and messages: There's an app in the Play Store that allows you to backup and restore them.
The titanium backup is a very good tool too. Use it.

The [Q] in your thread title should have been reason enough to post it in Q&A .
Please don't post Questions in General Section in the future.

just do another backup to ha the certainty to have a good backup and now can I try to flash my first costomized rom
thanks a lot dude
ciao
It's been a pleasure in helping you with your doubt. Happy flashing and don't ever forget to do a nandroid backup.

This reply may be too late in coming...but I'll post it anyway. First, the size of your created nandroid....17mb.....WAY too small....the size of the backup I made was +/-800mb.
Second....if you REALLY have to copy it to a PC, zip it with minimal compression first....I found from personal experience that it copies MUCH more easily and safely....
Finally, keeping personal data (contacts, SMS, lists of installed apps [not including app data]) safe. You can install apps that will make data files of your texts and installed apps that can be accessed after flashing a custom ROM to enable recovery and re installation, and for your contacts (if you store them on the phone instead of the sim card) you go to your contacts, press the menu button and select import/export, then export to SD card. If you use these apps (appbak and SMS backup and restore) and the export to SD card function on your phone, you will find that data files have been created by using them.....these data files MUST be moved to your EXTERNAL SD card BEFORE flashing your custom ROM. They will be perfectly safe there as long as you haven't played around with the storage configurations on your phone....which I don't believe is possible with a stock ROM anyway....
Good luck and happy flashing
Hope this has helped....if it has, click thanks

not so late dude
the problem is... I don't have a working backup still now!
I just flased cm9 and RemICS 1.5 rom and every time I tried to make a backup before flashing...
the first time I have the above doubt (as you can read above)
the second time I've tried to install CWM 6.0.1.0 instead 6.0.1.2 and the backup process is finish well (or it was what I belive ) then when I try to comeback to stock version an error has occurred in restore and I must re-do a flash with stock firmware because the SGW was freezed.
I don't know if there are problems with installation of CWM, the release of CWM (now I try with a CWM 5.5.0.4), with the type of backup files (n CWM6 you can choose the type of format file do you have from the backup process) but now before to flash another rom I want to have a WORKING nandroid!
thanks for your reply and your suggests too... maybe make I something wrong but I follow the tools on web and these are simple... maybe is only bad luck... I retry
Dude...if you read my thread here.......
http://forum.xda-developers.com/showthread.php?t=1846449
And specifically the replies posted by IvanKurnia, you'll find the links (and installation method) for the version of CWM that I'm using.....with success. When you make your nandroid backup, you need to make sure you have enough space for it to complete as you don't get any warning about lack of memory....the backup process will simply stop....and unless you know what to look for, you may not realise.
I'm not totally sure if flashing different versions of CWM on top of each other will cause instability or not....maybe somebody else can answer that one.....
I'd advise getting as much info as you can about EVERYTHING! before you make any more modifications to your phone.....read as many threads and ask as many questions as it takes.....most members of this community will be happy to help (though there are one or two who have a superiority complex...lol)....it's better to ask a hundred questions and get it right, than to ask none and turn your phone into an expensive paperweight.......
CM9...I don't HAVE to.....I just.....can..
first of all: I wanted to write mate not dude sorry for my bad english...
thanks keithross
I read your thread and all the replies in it...
yes the metheod for flashing the CWM is the same I knew. I prefer to flash it whit odin.
I don't think I have problems flashing other versione because I must do a replace of stock firmware before: I set the cell in the status as new... then I reflash on it the CWM.
the only thing I don't have made is to set on USB debugging ON... uhmmm maybe is this the problem?
I try now to flash, make a nandroid, try recovery by nandroid to understand if nandroid works! If not... I try to instal CWM witn the method has showed by ivankurnia
for free space I have enough space in my SD ext card (3gb ca.) and not so many app installed... and yes I use often forum and I think these are the greatest resource on the web xda for android is "the bible" I think so!
p.s. your thread has so many informations I need...
Hi Bennymax, I found ivankurnias method the easiest to use....I'd tried ODIN without success....but successfully installed CWM on the first try with the terminal emulator/busybox method.....others have successfully used this method too. I do still stand by my concerns about flashing different versions of CWM on top of each other as I've come to believe that the recovery partition is separate to the ROM partition and that changing the ROM partition has no effect on the contents of the recovery partition. I hope I'm wrong about that, and that the issues you are having with nandroid backup and restore are as you say bad luck....but I'm not convinced.....having said that, I'm not a developer, and I could be wrong. I feel that it is something that needs researching just in case the luck you've had is not bad, but good in so far as you haven't bricked your phone yet......
Anyway, good luck however you decide to proceed....
Keith
CM9...I don't HAVE to.....I just.....can..
Hello XDA, I am on the process of moving from stock 4.2.2 on my DUOS to a Custom ROM, I haeve my device currently ROOTED, with CWM, SU app, ROM has been backed up using CWM/ROM Manager, Stuff synced with Google, Apps backed up with Titanium, need to be sure I have a recoverable EFS backup.
Now here is where I halted the process because I have been reading quite a lot and talking to people used to flash their phones but none of them have a GT-I9082 and we aren't sure that about what partitions are vital for an EFS restore.
I know I have backed up using EFS Professional my EFS partition but other than that no other partition was available (Used International Variants option as filter, since my device isn't listed by default). I added manually a filter named ftaer my device, the way I made it was reading the PIT file and selecting all the available partitions, but I'm still not sure whether that would suffice to recover a broken EFS.
I would really appreciate any input from people who already recovered their EFS successfully either using EFS Professional or any other method, please tell me which partitions have you backed up.
Hello, as some of you know, after I used Keis to backup my device, did a factory reset and restored the device, I found that some of the data and files were not backed up. Since Keis cannot do a good job in backing up the device, why do we need Keis? Is there any good app that can do a full backup/clone so that after restoration, the device is like it is before a factory reset? From Helium Wiki, it says that the app does not backup photos nor videos. It also does not backup system files, widgets, device specific apps like s-note or s-memo, contacts, etc.
I usually keep personal things ( documents, photos, etc. ) on the removable SD card, and then use TWRP to do the backing up of the device. Quite frankly, having TWRP backups has saved my bacon many, many times Another option would be Titanium backup, which has been around forever and has a very large user base.
Thanks. By TWRP, do you mean TWRP Manager (ROOT)? I don't know if ROOT means it only works on rooted devices. As far as I heard, Android 4.4.2 on our device does not allow saving on SD card. How do you do that?
Yes TWRP is a replacement recovery which you boot into prior to the OS booting using particular button combination. By loading prior to the operating system it allows for the complete backup of all files (system and all).
Essentially for the best possible outcome with regards to backup and restore it is best to have root which gives you full access to system files for backup and more importantly for restoring which requires the ability to overwrite system files.
One of the reasons I insist on having root on my devices is that I keep a backup of all applications using Titanium Backup such that if I'm ever disatisfied with the way an application update performs (lets say a developer updates their app and the new version has bugs in it) I can always roll back to the prior version if necessary. It's very handy for this purpose.
I have been using TWRP for a while and have been saving backups regularly on the external SD-card. I have restored many times after testing some custom ROM.
Today I tried to restore my most recent backup and after it was done, it throws me back into the boot screen.
I can see a long list of previous backups but when I select them I observe the following, which I had not paid attention to before:
1) the most recent backup involves the partitions System and Data
2) the three next backups show no partitions and TWRP refuses to restore them (and I could swear I had restored from them in the past)
3) a very old backup shows System, Data and Boot
4) an older custom ROM backup also shows System, Data and Boot
Can someone please tell me what you think the problem is here? I cannot go back to my most recent backup.
Make sure you've not somehow ended up with 2 twrp folders with different id's as twrp will only recognize the current Id.
If that's the case copy the backups into that folder.
There is only one TWRP folder. It seems some backups contain "Boot" "Data" and "System" and some backups contain only "System" and "Data" and are missing "Boot".
As I only followed the "defaults" when I did the backups, I need to understand why in some cases it did not save "Boot".
Would you know why?

I've no idea, never come across it, unless you accidentally unchecked those partitions?
In any case none are full backups.
You should make a backup of EFS and modem too.

I have managed to restore an older backup which had Boot, Data and System partitions. I then restored the latest backup which only had Data and System. It now seems to work. I started it up and it all appears to be in place.
I then booted into TWRP and selected to do a backup and it had automatically selected the Data, System and Boot partitions. Why did it leave Boot out of the previous backups I do not understand but will keep an eye on it from now on.
Regarding the EFS partition: Originally I installed the stock ROM using ODIN. Does this mean that all the partitions were created during that initial installation? Or was the EFS partition present beforehand?
EFS partition is not part of the firmware, so is extremely important to back up, probably the most important of all to backup as it contains a lot of information that could render your device useless if it gets corrupted.
OK, thanks, will do it now.

Can we make EFS checked by default? I had no idea that it's that important..

"Important" - is there anything other than the IMEI to worry about? On my other, dual-SIM Chinese phones, I used to change the IMEI as I liked.
Yes. And it's ONLY 20MB, compared to the other partitions which are many GB in length.
And Restore should be made to have the partition unchecked by default.

Check it and it should stay checked.
And yes it contains a lot of important stuff related to imei, wifi, network, Bluetooth.
Lose it and you could be in trouble.
Search Google for more info.
Please somebody could explain exactly what i need to backup in twrp? The system image and vendor image are needed? What they are in def? Thanks in advance...
From this forum, "the /vendor partition would only need backing up if you manually made changes to it yourself (for instance, if you use Layers). Otherwise, you can just use the vendor.img from the factory image if you need to restore /vendor."
From this forum, "According to TWRP in regards to System Image... this is 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."
"The default backup options in TWRP are system, data, and boot. For most cases, this is sufficient for backing up a ROM. (Note that in some rare cases, boot isn’t available for backup on certain devices). If your device has the option, backing up android_secure and/or sd-ext may be a good idea. There’s usually no reason to back up cache or recovery (recovery not available for backup on some devices)." Answer found here.

Also make sure you backup your efs and keep atleast 2 copies eg 1 on phone and another on computer or in the cloud etc.
You only need to restore this if you loose your imei number due to corruption etc.
