If I install a ROM ex. MIUI 1.5.6 X-part, what changes does it makes on my SD card? Will there be problems adding another rom after that? Do I need to reformat / partition on my SD card if I should go to a different ROM with a2sd+?
Another question:
If I made a backup of everything in recovery and want to restore do I have to wipe everything before restoration?
The rom won't make any changes to your sd card. however you wil need to format the card for the a2sd because you will need to create an ext3/ext4 partition(use rom manager or some kind of partitioning tool for pc eg: MiniTool Partition Magic Home Edition (free). no problems should be encountered if you want to add other ROM's after that as long as you wipe before, usually Chefs tell you what to do before flashing their rom.
For the 2nd question, no, you dont need to format if you want to restore a backed up rom
Goodmorning Sirs,
I have a strange problem...
My desire is happily runnig InsertCoin 1.0.8 with CM7 boot since months..
I am running also CWM recovery 3.0.2.8...
I'm giving a step by step description, in order to get you aware of possible upsets.
This morning I decide to install S2Ext program and strangely i found that
EXT partition was not recognized.. I reboot and have the same problem in S2E but everything was running fine... I was fearing that something gonna happen so I decide to have a nandroid backup to get clear that if something goes wrong I can restore all it back.
I successfully did a nandroid backup..
but..
after reboot I'm stuck at splash screen....
worried I went to recovery and I could not mount the sd card..
so no nandroid restore and nothing no sd no boot (A2SD+)..
Either usb mount is not working..
I verified that FAT32 partiotion on sdcard could be read from my laptop..
WHAT CAN I DO?
It's a recovery problem?
Sounds like the ext partition has become corrupted, so nandroid/cwm won't be able to write to it properly.
Stick the card in a PC reader, then run gparted on it - recreate/format the ext partition at the end (without formatting the FAT), then stick it back in phone.
Nandroid should then be able to restore backed up .img to it.

Easily fixed.

What do you want to know?
I know I'm not the first person to post about it. I've seen this problem mentioned numerous times, and what follows is the simple instructions of re-flashing cwm. However, let's not jump ahead of ourselves.
The problem:
I do not have an external sd card. When I go into cwm 5 and try to create a NANd backup, I'm told the cwm cannot mount my sd card. I would like to create the backup in the internal card. If I go to Mount and Storage and try to mount sd card, I'm told the same. This basically boils down to not being able to make a backup via cwm. So far I have found no work-around except to flash cwm 4.0, but this gets "undone" every time I update my rom of choice (ie. StarBurst). Naturally, I would like to find a way to make backups without having to revert cwm to v4 every time.
PARAMETERS:
1. I do not have an external sd card.
2. I have already tried re-flashing cwm v5 numerous times, since most posts simply instructed to re-flash the latest cwm.
3. CWM v4 does detect (and allows backups to) the internal sd card.
4. I paid for Titanium Backup Pro and use it regularly. I am,thus, not looking for a simple "restore data with Titanium" answer. I would like to make NANd backups in case I need to revert changes after a bad flash, etc.
So, wall of text over, does anyone have any answers / insight into the topic? I'm sorry if this is a duplicate, but I promise that I did search first, and apart from sporadic posts on the subject, found no real match to my situation.
Thanks

The functionality was taken out. I don't know the details, but something was getting borked up with internal sd. I believe your options, for now, are limited to what you already know.
1) Re-Flash v4 every time you flash a kernel or ROM with v5
OR
2) Bite the bullet and buy an SD card. I'll admit, I don't really get why this may be a problem, but we all have out reasons for things.
Anyhoo, I hope this helps. Maybe someone more intimate with CWM can chime in with more info or correct me if I'm wrong.
This just seemed weird to me.
Say if all my apps are installed to the SD card. I back them up, and flash a new rom.
When I goto reinstall them, aren't they STILL on the SD card. Does it all get overwritten?
I just don't get what will happen. I don't want to flash, then have all my apps messed up.
Did you try it? If you can use custom roms then you probably use the recovery, so just backup the Nandroid and try it. Or are you saying you did try it but it didn't work?
nono I'm asking, if I restore apps after I flash a custom rom, back to their original locations, the sd card, when the data is STILL there, what happends.
I mean when I flash a rom, the system is wiped, but the actual applications and data of the programs I have, are still on the SD card, does it overwrite them when I try to restore them?
Probably would overwrite then
Ok, solved problem by just moving all my apps back to internal storage.
TIME FOR SE.TWEAKED!
I own a Galaxy Tab PRO 10.1" Wifi (SM-T520).
I have the stock ROM, rooted and with TWRP. And SDfix...
I have tried fat32 and ext4 on MicroSD, and without MicroSD. No difference.
I cannot boot any custom rom (Stuck at Samsung logo). Sometimes when I try to install a rom, it fails, or reboots TWRP.
I also encountered problem when trying to restore a nandroid. No DATA partition can be written to, restore fails. (after reboot recovery, its no problem to restore)
Angry Birds Epic does not work. It stops at "Loading Levels", and sometimes it fails to start, and says its not installed.
Spotify says that that it cannot be used because it has no storage.
I can access the partitions, but they are not writable. A reboot is getting the internal/external SD to be writabe again.
So, what is the problem with the partitions on TabPRO? or is it the Samsung android rom thats the problem?
Can it be fixed?

Try installing FolderMount from the PlayStore. It can detect and fix issues with your partitions. You just need to run it, then reboot. I seem to get issues writing to my data partition after I install TWRP, on my SM-P900. FolderMount fixed it quickly and easily.

FolderMount did find an error, and fixed it, but same result
And it "fixed" the same problem as the SDfix app did.
But, I still made some progress. I managed to install a custom rom without error, and fully booted.
Team Freeze Rom installed fine. The rom is just under 800Mb. So i thought maybe it was some faulty memory sector on my tab.
Then I tried to flash GigaWatts ROM, and it failed. Same with ProPlus Rom.
When restoring my last nandroid, it fails when writing DATA partition.
Then I tried to restore my first nandroid, from "stock" rom, and it restored just fine.
First nandroid was from internal SD, and latest was from external SD. Made me wondering, so switched yet again another MicroSD, took a nandroid to it, and tried to restore. It fails again at DATA.
Then I tried t install GigaWatts ROM from internal SD, instead of external. Works without error.
Sooo.... I can flash custom ROM`s from Internal Memory, and restore from Internal Memory
Not from external SD.
Still, I do get internal/external SD dropouts, and getting "no space left/no memory to install on", which can be "fixed" by a reboot.(Still, it should`t be like this, and are quite annoying.
But, still no luck on getting past the "Loading Levels" on AngryBirds Epic
Where is the root of the problems? Faulty device? Android ROM? TWRP making trouble?
Please guide me if any logs should be provided to find out where the problems is, if i`m not the only one with these problems.

You can try flashing a stock ROM via Odin, and start from scratch. Factory Reset, Reroot, install twrp, etc. If you still can't write to /data properly, you may need to find a .PIT file and repartition your internal memory using Odin.

I have had to reflash stock with Odin 4 times by now, and it has been the same pain every time.
I was hoping not to use re-partition, so I will wait and see if some new info will come by from other users, as I see there are more of the users that struggles with flashing custom rom. (Stuck at samsung logo, installation fails)
So, will hold off for a few days, and if no new info about partitions, rom flashing, low memory, sd cards not mounting correctly, etc, then I will try re-partition...
meanwile, I`ll investigate som more on my own, read overall the internet
Ok, so i have tried and failed, and learned something on the way
Ext SD is useless for flashing rom, nandroid, etc within TWRP. It does not mount partitions correctly.
If I make sure DATA partition is mounted in recovery, and only use Internal SD, everythin flashes, backups and restores just fine
(Mabye an issure with TWRP?)
SDfix, or FolderMount fixes write permissions to Ext SD in rom to use TitaniumBackup, games, downloads, etc.
Hopes this can help others in simular problems.
And thanks to all that have helped on the way
