i had converted my external sd ard to internal storage on marshmellow.....I flashed a new rom and expected them to be auto detected, did I do something wrong or do I need to go back to my old rom->titanium backup->restore--the old way?
As far as I know, the encryption key is per installation. If you don't have a backup of the system it's probably gone.
Even if you had the original key, I doubt you could persuade your new ROM to use it. Neither could you do that with a new installation of the original ROM

Hi, question, I want to change my microSD card, but that's of course where I installed my ROM (UnNamed) from and has other information that I've stored on it so far from the phone.
Can I just copy all the files from the first SD to the second or would this not work? And would it affect the ROM if I did so? If I switch microSDs do I need to reinstall the ROM from the new microSD? Thanks.
No worries about switching your micro sdcard. The rom zip file is like an installation file. Once installed, the rom does not need it for it to continue to work.
Just save the files you want to keep.
Unless you changed it, the default save location is the internal sdcard, not external. To make sure shut the phone off, and take the micro sdcard out. Boot it back up and make sure all your files are still there.

Hy guys, there is something I dont understand about nandroid. I flashed my rom, kernel, downloaded apps, change setting, homescreen etc. and now i would like to back it up exactly as it is. I read that nandroid is best for that but it doesnt backup sd card? whats up with that. I look at my sd card with root explorer and there are many folder and files that were made by apps when they were insteled on the phone.Does it backup that also? Also i have many apps, apps2sd, will it make backup of them also?
It won't back up your entire phone onto your phone. It would get really big with all the music, videos, etc, that a person might have. If you have your external card mounted then you can attach via a USB cable to your computer then either with adb or with a file manager copy all of /mnt/sdcard youlle get the important things that nandroid does not. The exception I can think of is that it doesn't seem to back up your modem firmware, so if your partial to a particular one then just have it as a flashable file.
Ok, thanks, so it doesnt backup internal sd card because someone told me yesterday that it does? If i copy the entire sd card to PC and latter copy it back to mobile like that will it work. First i recover nandroid backup, than i format internal sd card and than copy all the files back to sd card.
A Nandroid backup will copy a lot, but it can't copy everything or there wouldn't be room on the device for it to be practical. It is quite supprising how much it will keep; it just isn't a complete backup solution is all.
Addressing your question though, as for copying the entire sd card, you really only need to copy the folder /mnt/sdcard or /sdcard ; the latter is a symlink to /mnt/sdcard
If you try to copy your entire sdcard then it is possible to end up with data from partitions that will take forever to copy and that you really don't want, for example /proc on the phone is just kernel information that doesn't even exist when the phone is turned off. To keep things simple, everything is part of the ROM and kernel except for /mnt/sdcard and in the case of and external sd card, /mnt/sdcard/external_sd but the latter (/mnt/sdcard/external_sd) will be copied along with the first one provided it is mounted when you do it.
The only other exception to what needs to be backed up is a partition called /efs and there are various tutorials with various methods about how to do that. I would follow one of them rather than just copying the data out as its a partition that holds unique information about the phone that it can't function with if it gets messed up. This is more immediately important and I think there's quite simply some apps that will do it for you if you look at the sticky threads here. The files will be on your phone though so you'lle want to pull them off on to your computer for sure.
As for your friend's advice, though, you won't typically ever need more than a Nandroid backup unless something happens to that other data, for example if there's filesystem corruption. If you do a restore of your ROM then it still retains all your music and photo goodies or whatever, app settings get wiped though where they are retained with Nandroid. The only thing that I'd worry about is if the impending update to Ice Cream Sandwhich somehow wipes suff, or if you play around at the command line a lot make a mistake unintentionally. If it weren't for the updates and beta ICS releases we're seeing then I'd simply be telling you not to worry about it, but to back things up and be done with it.
By the way, doesn't Kies back things up? I don't have it so I don't remember but it seems like that's how I initially got things onto it and that it has a sync option. Perhaps this is enough?....

Man just do the backup and don't worry about the sd card files/folders. The reason it doesn't back them up is because they stay there anyway. Eg, if you uninstall an app, a folder that was created by it on your sd card is still there. Flashing firmware, including wipe versions doesn't touch the 11.5gb internal storage or external storage.
BTW, most of my internal sd card is used up and 25gb is used up on my external card. If the backup was to include those a 64gb memory card wouldn't be enough.
Between the S1 and S2 I've backed up and restored over 100 times, including after fully wiping the phone (but not formatting sd cards) and the phone always looks and functions exactly as before, including apps.
So, only copy memory card files to PC if you intend to format the internal / external cards or if you are worried you might lose stuff if the memories become corrupted.

Thanks guys for you help. I dont use Kies also so i dont know and, yes, i format sd card before flashing every rom so i would probably format it also before making restore of nandroid backup. Also when i delete some app a delete a folder created by it on sd card. OK, than i will make a nandroid backup and copy mnt/sdcard on PC so if it ever gets corupted i can restore everything. As for efs folder, Neak kerenl made a backup of that automatic so i just made a copy of that on PC.
Every so often I go though the folders on the sd cards and clean them up a little but I have never formatted the sd cards. I don't really think you should do it with every flash.

Hi All
I have searched the forums for an answer to this, to no avail. Its not an easy problem to search, but apologies if this has been previously discussed..
After some years of owning and flashing various android phones I have suddenly come completely unstuck. I am not sure what has happened, but I suspect that my internal storage has died. No matter what Rom I load (including returning to stock flashed via Odin) I cannot see the phone's internal storage (i.e. the memory that used to appear as "internal USB" or similar). Instead, the "SD card" is being emulated under the folder "0" in the phone's main storage... I am unsure what is happening here.
This happened after flashing the latest version of Omega Rom (v44). Everything went completely fine as usual, I have no idea why this happened. When I rebooted the Rom had installed but internal storage was missing as described above. For some reason the AOKP elements of the Rom are not present, but the system does seem to work.
I have inserted an external SD card to see if the phone would just use that. No effect. It still appears to be "emulating" the external SD card.
I am not sure where to go from here. I can accept that my internal storage is dead. However, as described above inserting an external SD card still doesn't seem to allow the phone to work normally. It is still trying to emulate the SD card in the phone memory, even on a stock rom. On custom roms this seems to stop the AOKP element from working and I end up with some kind of half way house of custom rom and stock Samsung stuff... its bizarre!
Any help or even just thoughts as to what is going on here greatly appreciated.
I remember that in CM roms there is an issue with the 0 folder thing, but not familiar with it. Maybe someone with more experience could recommend you some action steps.
In case you could always try a full wipe (mega wipe) as it includes your sd card (internal) and leaves nothing on the phone. This will enable you to start from scratch (have a flashable rom on your external SD though).
I'm trying to create an image of my device, but the memory of the device is way more than half full.
Since ClockWorkMod is trying to backup to the DEVICE memory, and not the SD card memory, it obviously doesn't have enough room to do so.
How can I change the location of where it does the backup?
I'm using ClockWorkMod recovery v4.0.1.5 with CF root, and I'm quite a newbie when it comes to ROM changing and everything, never done that.
Thanks
In the backup/restore settings in CWRecovery, you should have the option to backup to internal/external storage. Choose external if you don't have enough space in internal.

I do not see any "settings" in the backup/restore.
Also - I cleared about 700MB from my device memory, leaving it with 10GB used space and 2GB free, and it seems like it did a backup which its size is about 2GB leaving me with about 100 free MB. How does it make sense? doesn't it backup the data like images and videos?
Will still prefer to try and backup to SD.
Thanks
CWM will make an 'image' of the phone at the time you make the backup minus the modem & external SD card (if you have one). If you have photos/videos/whatever stored in the usual place on the internal storage these will be backed up. That backup size is normal.
Do you have an external/separate SD card, or are you talking about the two separate parts of the internal storage; you have the part that's used by the 'system'; & the 'userspace' which is normally referred to as 'sdcard' ? If you are using an external/separate SD card, there's definitely an option in the backup & restore settings to backup to external SD card (I'm looking at that menu right now).
I have a feeling the version of CWM you're using may have something to do with you not having these options; 4x is ancient, I don't even remember what options are in the menus of that; we're now using 6x.
Perhaps you might want to use a kernel that has a more recent version of CWM if that's the case & it's not allowing you do what you want ?

I did mean the external storage, yes.
I tried to update to 6x but it stayed the same version.
Anyway, if you're sure it makes sense that 10GB became 2GB after backup, then I'll trust that and will use the backup it created in the internal storage.
What I meant was, you said the backup size was ~2GB; that is indeed normal. If you attempt to update CWM independently of the kernel, you will revert to whatever version is baked into the kernel when you next reboot. If you want to update to a permanent later version of CWM, you'll need to flash a kernel that has said version of CWM.
if you're on PhilZ kernel, you can choose to compress the backup file. (low, medium or high compression)
You can also get a smaller file size, by uninstalling apps you certainly dont need. You can clear off cache files.
For cleanup i recommend Clean Master - search playstore
Hi all,
I stuck with thinking and perhaps somebody knows if this is possible at all and how to:
I have an Onyx and I am on new bootloader, TWRP by BlueSpark and ROM is Crdroid Nougat 7.1
This works perfect as daily driver.
Usually I do nandroids out of TWRP for proper backup before trying other things and I use the OTG connection with a 128GB drive, also worked perfectly so far.
Lately I added a microsd instead of the 2nd SIM, and I migrated it to become available as internal memory, because I ran out of memory.
Also this is working well and as exepted.
Now I would like to go into TWRP and make a Nandroid. At this point I am not able to backup internal memery including the migrated SD card. I can only backup the "real" internal part, so I do not have a real snapshot of the whole phone to be on hand if needed to be restored.
How can I achieve that, I can't find the clue? There is no relevant partionion I can add, whatever? Is it possible at all? Perhaps it is related to the TWRP version?
Thanks for your thoughts,
D.
I don't have a link for it but I'll at least tell you what happened. When you choose to use the SD card as "adopted storage" Android encrypts the SD card so that it can store sensitive app data on it securely. Since it's encrypted TWRP cannot read the SD card now at all. I think there's a version of TWRP on here (maybe by the developer of Blu_spark?) that is for devices that are encrypted but since I myself don't use encryption I don't know where that is on here.
