64GB Micro SD Card, EXFAT, and TWRP Recovery

BestBuy has the class 10 SanDisk 64GB micro sd card for 43 bucks.

I took the plunge. I've been reading a lot of posts that claim it doesn't work on the Note 2, but an equal amount that say it does. I know you can either format it in fat32 or exfat. Exfat allows you to store files larger than 4GB, such as HD movies.Is there any other advantage to using exfat than the 4GB file size option? Also, I'm pretty sure exfat won't work with TWRP recovery, right? I'd be stuck with stock recovery if I opted for exfat formatting, right?

TWRP is a recovery not a kernel. If you're running stock kernel exfat should work.

It will not find the your SD card if you try to do a backup and restore if you formatted the card using exfat. I wonder what would happen if I went ahead and installed TWRP, but when I did my back up I inserted a smaller, back-up card that formatted with fat32. I could reinsert the fat32 card only if I needed to restore the backup...

Can you do a backup to your sdcard? If so, how?

I have no idea. All I know is on my ATT Inspire the nandroid backups were always stored on my SD card using CWM.

For CWM, if you want to back up to extSdCard, you have to select "backup to external card" or something like that.
for TWRP, the latest version supports exFAT & when you are in backup, you can select if you want to backup to internal or external sdcard. its a radio button.

Pretty sure I saw one of the TWRP developers say today that it does not support exfat... could be wrong though.

People are saying clockwork mod rom manager does not support note 2 yet. I think you can use Odin to install it however. Maybe it's just that the app doesn't support note 2 yet. I wonder if I should just wait until the goole play clockwork mod app adds note 2 support. I suspect it won't be long.

The latest version supports exFAT because I'm using TWRP with a 64gb formatted exFAT & the dev released a version that supports exFAT in the TWRP thread.

You don't need to use ROM manager because CWM & TWRP does everything it does and if you want to update CWM then you'll have to use ODIN.

Can you post a link to the version of TWRP that supports exfat. I can't find it. Is it just the latest version, 2.3.1.3?

Just download GooManager from the Play store and select to install Open Recovery (like previous poster said). The first few releases of TWRP did not support exFat, but the dev was nice enough to add it.
I just booted into TWRP and confirmed it's there.

Thanks.

Thanks to everyone for clearing this up! The developer of TWRP should consider noting that TWRP now offers exfat support on the TWRP OP. That's a pretty big deal IMO.
My phone arrives Monday, but my 64gb card probably won't be here for a while. In the meantime I will be using a 32GB fat32 card. Any harm in just powering down the phone and switching cards when the new, larger exfat card arrives? Switching cards never seemed to be an issue on my old Inspire. I mainly just use the card to house music and movies.

{Q} Is there a stock rooted JB rom?

I want to put my phone back to a stock rooted rom, is there one out there?
I've looked through the development forum but can't seem to find one that is just stock.

Also, just for good measure, make sure that you download team epic root from recovery zip just in case...so that if you lose root, you can get it back.

Thank you both, I did find them on my own after I posted this.
Somehow I lost the nandroid back up on my wife's phone when I put a 64gb SD card on her phone. It may still be on the internal memory, but I don't have her phone with me at the moment.

Not really. A 64GB card will work just fine with one exception. The recoveries can not access the 64GB card if it is formatted as exFAT. The ROM will handle it just fine but the recovery can only handle it if formatted to ext4 or FAT32. I still have my 64GB formatted as exFAT but I do not use if for nandroids. I either backup to internal memory or I pop in my 32GB card for recovery use.

Yes I formatted the 64gb card to fat 32 before using it in the phone.
My problem is I don't think I saved her nandroid back up from her old card, and the old one is wiped clean.
Could I use a nand from from my GS3?
I know I couldn't on my EVOs.

64GB Micro SD card issues, pls read

I had a recovery of my stock rom installed, and inserted a BRAND NEW (Bought it 30 minutes ago) 64GB SanDisk MicroSDXC card, bought from Bestbuy factory sealed. with the sdcard installed I recovered to my CM10.1 install and the SDcard does not work, it says "mount sdcard" but nothing happens when I click it. What am I doing wrong?

Should be in Q and A but to answer you only the stock touch wiz kernel and perseus support the 64gb cards....youd need to format it to 32gb or use a 32gb on cm10 if I am correct.

Not true. You should have no problem running a 64gb card on an AOSP rom as long as it is formatted to fat32. I am currently running a 64gb sandisk card and my current rom is liquidsmooth but have also used it on carbon, rootbox, paranoid as well as a few touchwiz based roms with no issues. Just make sure you format the card to fat32 and you should be fine.
Sent from my SPH-L900 using xda app-developers app

No support for exfat, so you'll have to format to fat 32, which defeats the purpose of a high capacity card.
(can't store files bigger then 4gb aka HD rips)
Although there are some hacks on this board that may work.

Xfat from my understanding only works on stock kernel and persus from what I remember reading unless the dev added the support so like it was mentioned formatting it to fat32 on that size card defeats that cards purpose....I should have been clearer since the OP said it doesn't work on cm10 but did on his gfs phone that seemed like why to me. :thumbup:
Sent from my SPH-L900 using Tapatalk 2

So, can we expect ex fat support on cm10.1 anytime soon?

sd card issues with aosp/cm roms....................that's why I stay away from those roms in that thread...........those roms look bad-ass, but not worth sd card issues, i.e. reformatting to fat32 and such..........not worth it.

I wouldn't get anything over 32gigs...unless you plan on downloading a bunch of pics, games, videos and apps..my 16gig is perfect for me.

The above poster is correct if you want to run aosp or cm gotta format to fat32..
And yes some kernels other then stick and Perseus have issues reading exfat.
But there isn't a Damn thing wing with running perseus they are dope.

SD card not mounting/cant flash ROM

I have CWM 6.0.3.1 installed and im rooted. When I go into recovery the SD card does not mount. So I can't flash a new ROM. I tried to format the SD card in the phone but that did'nt help either. I have the stock ROM with 4.1.2. Can i use the stock recovery to flash a ROM or do I need CWM? When im in stock recovery the card is mounted and I can read it. Its just in CWM it will not mount,
btw-im trying to flash cm10 dont know if that matters.

Why not Odin flash the stock-rooted rom and then you can flash cwm/twrp custom roms or just stay stock rooted.
Either way it will fix your mounting issue for sure.
Big mistake if you're going to flash cm10, you are just asking for problems unless you like experimentation.
Good luck!

I did Odin flash like you told me in another post. It got the phone back up but I cant get the card to mount in CWM. I guess Ill try TWRP. Thanks for the heads up on cm10. I could stay stock but I wanted to increase the CPU speed and get some features stock does'nt have. I don't want to turn this into "whats the best ROM" but can you tell me a good one without problems.

I guess it has to do witht the SD card. I used a 1gb and it works fine. But i still need to figure out how to make the 64gb card work.

Not sure that the 64GB cards work on AOSP. Pretty sure you need TouchWiz ROM for that.

The 64GB are in EXFAT format and I don't believe CWM can identify the card in that format. You will need to format the card to FAT32 on your pc and then the recovery should read your card.

That's only one of many reasons why I always try to advise people to stay away from AOKP/AOSP/CM roms.
All of them have inferior cameras and none have wifi calling.
Those roms were meant for developers or for those who like to do a lot of experimentation.
I just got a 64gb sdcard yesterday and it works perfectly, I had a 16gb card which worked perfectly too.
The rom I am using now is jovy's Stockorama v1 which is not exactly stock, it is deoxidized and debloated
and has many mods and lot's of improvements when compared to stock rom.

Weird, when I go to format my card I can only do FAT32 or NTFS. No other options are there, its win 7.

All sdcards come pre-formatted with FAT32 as default because they perform better and
faster than other formats when used in cell phones and other small devices.
The only advantage of formatting sdcards with other than the default format is when you are
dealing with files larger than 4GB in size. Most people will never have to deal with files of that
size unless they want to use their phones to record video for more than 8 hours continuously.
There are many 3rd party windows 7 utilities which have other format options like MiniTool partition wizard it's a free
(for home use) partition manager that can format a partition as EXT2/3/4 from windows - http://www.partitionwizard.com

I know the aosp/aokp/cm based roms do recognize most sdcards but we are talking about 64gb sdcards
and that's where many of those roms have a problem recognizing and formatting the 64gb sdcard.

Hmm.. That's odd. I'm currently running Liquidsmooth 2.4 with my FAT32 formatted 64 GB SanDisk Class 10 card with no issues. It's been almost a year now since moving from EXFAT.
It has worked on both CWM and TWRP recovery for me.

Ext SD Card Scan Disk SDXC 64GB Won't mount in AOSP 4.2.2

Hey guys, I am hoping someone, anyone at this point can help me with this issue and question. I have a 64gb Scan Disk SDXC External SD Card that I formatted to Fat32 when I first got it.
Everything was good, up until last week when I decided to return to stock and reroot becuase I was having some other unrelated issues. Anyway when I did, I decided to format the Ext SD Card in android on the phone.
Now to my problem, Now my Ext SD Card will not mount in any AOSP 4.2.2 Rom, however WILL mount in TWRP and CleanRom and TW.
SO did formating the SD Card via the phone in settings make me lose Fat32?? If that is the case then why will it still mount in TW and TWRP?
When I try to mount in a AOSP Rom it just tries to mount and says preparing and then doesn't.
