Placeholder thread for my future guide on how to install android on an EMMC. I have acquired a 256gb EMMC chip. Its arriving soon. I will be experimenting with it and sorting out and identifying the issues that might come along.
If you are interested, feel free to provide input. My end goal is to run android, linux on the NAND natively in order to avoid the bottle neck an SD card might provide.
I have two ideas:
One is to replace HOS with android on the nand while running HOS via emummc/emunand. This is so android utilize the read/write speeds a nand chip can provide.
The other is to partition the EMMC to run both HOS and Android natively. Since this will severely reduce the amount of space available for HOS. Going this route would probably require a bigger EMMC chip. I purchased a 256gb chip just to try this. I don't think you would need much more than 124gb. Especially if you will be saving all your ROMs and games to an SD anyways.
I’m going to attempt the second idea first since thats what I would prefer. Although the first may be more attainable for most since it will be easier and not require another emmc chip.

While I'm really interested how this turns out I'm asking myself if the speed difference vs a good micro sd card is that big.. Switch has UHS-1 support right?
Of course I know in theory emmc is faster than micro sd card but in practice it may not make that much of a difference. I asked myself the same question back when I got my odroid hc2 single board computer. It has both a connector to add a emmc module and a micro sd card slot. I went with sd card. I read that in this case it comes down to the random read/write speed and at least in my case that didn't differ that much on sd card vs emmc.
Still, go for it, I wanna see how it turns out
I am mainly concerned with data integrity. An OS can perform 1000s of read write operations. Would rather run everything off of the EMMC to avoid burning out my SD card prematurely.
Ha, that is exactly what I asked Bylaws several weeks ago.
I mean I am not banned but I either use CFW (EmuEMMC - SD card), L4T (Sd card), Lakka (Sd card) or android (Sd card)
EMMC is just sitting there. It wouldn’t be that difficult and you would have faster speeds, the EMMC is very fast, and you would get to use the SD card slot as an actual Sd card slot! If you find a way, please share.
But I get a strike for creating a placeholder thread. Great.
I wonder if that possible to be a EMMC 128GB used for everything like:
32GB for Android
32GB for Linux
64GB for Nintendo Switch console
so i can change between the OS on Hekate
It might. Thats what I’m hoping to do. My console is banned so i’m not at risk, but once I’ve sorted out the process. I’ll be putting disclaimers out there.
This whole process provides a huge ban risk so if you buy an emmc chip. Do so at your own risk.
Wait Tito are you currently working on achieving this??? Awesome!

Yea my modded switch is banned as well (I have a secondary legit switch) So im all over this once u figure it out!
If anyone who's interested could find a source for the 128gb EMMC module. I'd be more than happy to share it. Mine is still in transit and it was pretty expensive when I bought it.

(i forget the name of the chip but you'll find it ^^)
The problem here is that the Switch's NAND has hidden partitions that lock the NAND chip to the hardware. You will need to figure out a way to copy these partitions off your old NAND chip and write it to the new NAND chip. It can and has been done, however partitioning for Linux/Android/HOS has not.
I think you'll find this useful: hxxp://pascoe.pw/2018/09/switchnand.html (replace hxxp with http)
If you pay attention at the end of the write-up, you'll see information for resizing the HOS partition. Meaning you could theoretically partition the NAND for all three.

Thanks for the info! I’m hoping that all that is needed is to write some images to a few properly appropriated partitions and some configuration here and there.
L4T, and android call to different partitions and sector counts. So right now the biggest hurdle would be to change how each os finds its corresponding partitions.
I know the hekate ini setup can probably direct where the os boots, but then the os itself might not have a clue. Especially since everything so far has been configured to run off the SD.
I’m playing around with how to modify each boot.scr to point to a different partition. Some others on gbatemp are familiar, but I haven’t dug too deep yet.

Thanks for the link. Since we would need the board that connects the EMMC to the switch. I'd preferably only want to promote the full unit(The board and the new EMMC already soldered to it.). Some on here might be technically savvy, but it might be too daunting of a task to also have to solder on a chip to a small board(This is the case for me lol). Especially if they elect to use their own EMMC board as the donor board. I hope that eventually a seller on alibaba sells those boards, but I haven't looked. I just wanted to buy a premed unit.
For those that might already have the equipment and skill to put this together. It's good to know that parts can still be sourced. Some might even offer their services to others. I've seen that being mentioned here and there on gbatemp. So its not out of the question.
I bought mine as a full unit from a seller on bonanza.com. I don't know if the price is really worth it though. Here's the link if any are interested.

I think it depends on how the os is configured, for my sbc I use armbian (debian base) running from sd card. It's optimised to reduce wear on the sd card. But idk how it is on android. I guess there's good reason why android runs of off emmc rather than sd cards on the majority of devices (except speed).
I didn't know that there's a board for the emmc you can "just" clip on, this makes it interesting again ...But the set you linked is rather pricy It's crazy if you think about it. In china you can get a 128gb emmc module for 20 usd
If there'll be such set available with 64gb (I guess that should be enough?) for like 50 usb and some sort of script for partitioning the emmc that could be run off the sd card then I'm all in :laugh:
Finally got it! I’ll be posting a write up soon.
This is perfect for my needs! I revived my dock bricked Switch by replacing the USB-DP controller chip, so I have nothing to do with it now since I had already transferred everything to my working console, so I want to use it exclusively as an Android device for games and apps lol I can't do much of anything to help but good luck!
EDIT: Oh, this is an important question. Would I still require RCM mode? Or will powering on the Switch boot directly to Android with this method? I want to avoid using payloads for regular use. I assume not since the console's hardware boots straight from EMMC

You will most likely still need to boot from a payload in order for this to work. Unless hekate gets rewritten to support booting from the EMMC chip itself. Not sure if you can set it up as an SD and boot drive.

Injecting a payload will be required. Booting directly is impossible unless you somehow get Nintendo to sign a copy of hekate with their private key or install a modchip.

so just read up on swap and had a couple more questions. i understand that it changes the way your phone handles the ram different apps use but still not understanding the specifics. if someone could clear that up it would be wonderful also will this affect battery life at all? and last question will this work on the kernel that comes with das bamf remix 1.6.3? ( i think my phone info says dirty by adrynalyne #1 ) or do i need to use the one suggested in the instructions --> http://forum.xda-developers.com/showthread.php?t=1106420 here?
It turns a set amount of your sd card memory into ram essentially, and the less frequently accessed files are written to the sdcard swap partition instead of the ram, essentially freeing up the ram for the more frequently read and written data. I didnt notice any effect on battery life, and i guess the only way it would...was if it drew more power to write to sd...i believe you need to use a kernel with swap enabled like the one by imoseyon
Thanks a ton! that perfectly answered my question as for the kernel i figured as much. does anyone know if the kernel i mentioned supports swap?
Swap is created on internal space, the emmc not the SD card.
sent from a sweet paper weight.
Pretty sure I read from Adrynalyne that his kernels all had swap enabled even though he doesn't believe it works.
Mike
For windows users, swap is like your page file (just better managed). I see very little ever use swap on android though.

There are also whispers going about that doing this "could" stress the emmc too much and cause your phone to an hero itself. The emmc is also possibly the leading culprit in the GB reboot of doom. Too lazy to point to source but seen this about the forums.
Truthfully I don't understand why people are putting their phones through this. EMMC is limited to how many times you can write to it. Just like a SSD drive. The first thing people do with SSD's is to either disable the swap file (page file) or move it to another drive. Putting a swap file on your EMMC is just killing the life of your EMMC even sooner. People say that you'll never kill your EMMC chip within the lifetime of your phone. But the fact is, no one knows how many writes your EMMC chip will take before degradation occurs. It's all up to the user though. Just wish people would do some research and fully understand the technology within their phones.

+1....Adreylane himself declared that he would not create swap on the EEMC. If he does not recommend it, I am not doing it.
I would like to, however, figure how people have so much RAM remaining on their phones safely. I only get about 120/600 free 98% of the times without having to constantly close out tasks. People in the dev forum are reporting they have had 300-400 free on Froyo. We all know GB takes more but I am on Froyo still and only have seen my aforementioned numbers.
id heard of some problems on emmc but didnt realize it was such a big deal. thanks for clearing that up before i tried it out. and im having the same issue im only getting between 100-200 free mb of ram without a task killer. is there something were doing wrong?
I would like to swap the factory 2Gb HD in my Nook Touch with Glowlight. To do this, I realize that I must first open up the device. I must take off the back cover. Do I need a special tool for this?
My credentials:
I've been searching all day for any information on this, even remotely similar.
This would fall under battery replacement, FYI.
Rooting forums are not opening the nook anymore to get to the Nook Software.
Yes I have been rooting Nooks since they first came out.
I don't plan on rooting this device, just upgrading the HD.
I plan on using Linux and doing a "dd to nook.iso" (if you don't understand that, you probably can't help me.)
I don't need any help with the software side, just removing the plastic back without breaking it.
Thank you to anyone who can help me.
I don't think it would work this way. Probably those are IC soldered to a board, and pretty much useless to remove it. Ever tried using a larger capacity SD card?
There is no HD inside nook, memory IC is sandisk SDIN5D2 iNAND flash in TFBGA package which is soldered to pcb.
Have you got the skills to desolder/solder this kind of package?
No SD???
There is NO SD card that they put the Android OS on? That is strange since it is exactly 2gb on the Nook Touch Simple with Glow Light.
Haven't they always used Micro SD cards?
Is this a new attempt at trying to stop people from rooting?

Ooh! Side loaded SD card! Neat!
Alright guys, I noticed today that my Titanium Backups aren't on my mount/extsd storage, and I tried to change the backup location under preferences, but it wouldn't allow me. While checking my sd card I noticed the only file stored on it is my pictures? I tried downloading apps to sd in an attempt to move titanium backup, and that's when I realized I have a serious issue I believe. I was given a message when apps to sd opened that said, "this device does not have a real primary external storage, or the primary external storage is emulated"? Whatever the hell that means by emulated I don't know? The sd card was working in the last phone I used it in.
Biggest problem is that I'm rooted, so I can't return it under warranty! At least I can't to my knowledge. I'm in serious need of some help here, I purchased the phone at the T mobile retail store, so I don't know if I can sneak it past them somehow, or if I should maybe just (it hurts to say it) brick it on purpose, and pull the old" it just shut off and wouldn't turn back on" routine?
Please guys, any and all advice will be much appreciated!
Before doing anything drastic, have you thought about maybe reformatting the SD card first? If that doesn't work then try another SD card (they do go bad you know). It sounds like something that should be easy to fix. Whatever you do please don't brick it on purpose. It's not anyone's fault that your device is now acting up after rooting it. At least do them a solid and ODIN back to stock, then try to return it if that's the case.
Hi,
You should read this thread. It should shed some light on your external SD card problem and provide a couple of methods to get around it.

Yes I did format it to no avail, and I'm headed home soon where I'll try a different sd card. I don't want to brick the device, and I've had to unroot and return a phone before because of a hardware issue with the screen that wasn't my fault. The problem with doing that in this situation is that I don't believe there's a way to unroot it and go back to the stock recovery or reset the binary flash counter. As far as you saying it's not anyone's fault, it sure is my friend and it's not mine! I had a Galaxy s4g that wouldn't read an sd card two days after I got it & I had to return it. So, as far as being no one's fault, not true... It would be Samsungs fault, and rooting it had nothing to do with it. If I broke a device because of my own foolishness or stupidity, I would ABSOLUTELY NEVER try to exchange it! The entire basis of my spirituality is based on karma and I would suck it up & pay for my mistake but maintain my peace of mind. This however, I am not at fault for, and I shouldn't be responsible for faulty hardware just because I obtained root access.

Sorry for the frustration, but I just spent a heck of a lot of money here, and this is a very aggravating problem....
My TB backs up to the ext SD. I had the same problem you did. Too bad I can't actually remember what I did. :crying:
When you go into TB and try to select storage location...nothing comes up but the internal?
I think I manually moved the TB folder from the internal to the external...then went back into TB to select the location...then selected the Detect button...and it came up with a list of folders that I could choose.
It went something like that. Hope that sheds some light...(sorry I cant remember exactly)
FYI...the ext SD folder is under mnt/extSD...or something like that.
I forget to mention something else guys. I am able to copy & paste my Titanium Backups as well as any other files to the sd card. So, the phone recognizes it, and it will write to external sd if I manually copy things there, but it will not allow any third party apps to write to external sd? I also cannot move apps to the sd card? This is a HUGE pain in the ass! I bought the 16gb model because that's all the retailer I my area had, so the sd card is a necessity for me. If I'm downloading torrents or other large files this could be a problem. I'm really wondering if this isn't just my phone?
It'd be great if someone here with the skills could port this mod for us.

It basically makes the phone think that the external is the internal...and all files downloaded from the browsers or whatever app that doesn't allow sd access...to go directly to external.

Sorry nothing! THANK YOU! I was like 3/4 of the way to that idea, I had already copied the file, but I was just thinking maybe if I deleted the internal file, maybe now it will follow the one I copied to the mount/extsdstorage? I can't thank you enough for just confirming that this isn't a problem specific to my model. I think that this problem should be explained to everyone & stickied. This is a seriously confusing situation. Ppl who don't root or come to XDA won't have any idea why they're music, videos, or anything from third party apps aren't going to their sd cards? Some ppl may not even realize it? I don't know if it's been mentioned in another thread here yet, but I couldn't find anything in our forums about it, and I've been trying to figure out what was going on all day. I still don't understand what the hell it meant about emulated storage?

All stock Samsung Galaxies S3 do this. Google in their infinite wisdom is locking down apps so they can not write to an external card that can infect other devices.
Problem is we all want more control with our external cards and there are a lot of unhappy campers with this new "feature". Gamers are especially concerned because they can not install their games to the external card to free up more space.
This is a real strong reason to buy the 32gb model and not the 16gb. One could take the stance that they are forcing us to pay a higher premium for our storage when we purchase the phone.
As I said you can do the work around with directory bind until:
1. A dev comes up with a a patch
2. You install a custom Rom like Cm9 that has patched out this security policy.
Never mind... Now that I'm using better keywords to describe the problem, and searching outside of just the US variants forum, I'm finding threads... I feel like an idiot now! Some folks are talking as if this is better? I don't see it though. I did a nandroid after root, and it only left me with around 8gb or so with my apps installed. I know its faster memory than an sd card, but it's kind of a pain. I hope I never need to download anything bigger than 8gb... Doubtful ill need my phone for anything that big though.
Sorry for freaking out and making a big deal out of this issue, but I thought my device was defective, and I wasn't using good search terms. I should have been able to figure this out without cluttering things with a two Page thread.

Yes, I really wish I could take it back and pay the difference for the 32gb, but with being rooted its really not feasible. I was browsing XDA on my phone also, and I didn't even catch the link in your first post, I was only reading the links I your second post, lol. I really feel like a dummy here since my question was almost immediately answered. Also, the browser can act a little wonky sometimes on XDA.

Actually you are bringing up a valid concern and one of the first to do it in this section of the US version of the S3, my hat off to you!
It would be good idea to have a stickied thread in general that addresses this. That way ppl will be well aware of how to work around it. And yes, a patch for this would be great, because some may prefer things this way, and alot will prefer the previous standards. I for one don't like this one bit!
Put a stock rom on it and go into the store. Tell them you're having issues, they can order one on their end and send it out to you.
I would know. I worked there.
So, in short, I used Link2SD to move all my bulky apps over to my MicroSD card. As you can probably tell at this point, I'm somewhat new to Android and apparently that causes a whole bunch of issues. I'm used to dealing with Windows PCs, where you can easily have an small SSD dedicated for your OS and a large HDD for your media storage. I guess Android isn't as simple as that. I thought it was supposed to be better, since it is Linux-based and all. Or maybe I'm missing something. I did some research, and it seems possible but I couldn't find a straight-forward answer.
Can someone explain to me how to use your MicroSD card as storage for your apps without screwing them up? I'm sure this has been addressed before, but I'd like someone to at least point me in the right direction as to not mess anything else up further. Link to another thread perhaps?
In addition, now that most of my apps are screwed up, is there a way to undo this? I am willing to do a factory reset, if necessary, but only if it is the best fool-proof solution.
Formatted ext sd via recovery...now I can't install, add or even format. I tried on pc and with twrp again by even using repair and changing file system. Anyone know how I can format this card? It's a 64 gb SanDisk. I can't find any solid solutions online. Thanks.

I have no idea of your hardware, but 64gb is where the switch from SD-HC changed to SD-HC (technically 32 can be either, but generally 32 are HC) and older hardware that didn't explicitly support XC wouldn't work... It either doesn't see it at all or sometimes it will work until you get to 32gb, then you can't write any more data.. I have older SD readers that so both.
But any phone or reader for the last 3-5 yrs handle XC, which has a theoretical 2tb limit, SanDisk has a 400gb microSD.. Insane.
Anyway that's all moot if it used to work in your phone and reader, but just doesn't anymore. Mostly if they're pre-formatted is exFat. If you formatted in TWRP I think it probably defaults to ext4, but TWRP can do a variety of formats.
I got to say though, if you can't reformat it again and TWRP that doesn't sound promising. Perhaps there is an Android app that will let you format with more control than the default tool (I have no idea since the last phone I had with SD was a Droid running GB)
Sorry I didn't really offer a solution, I have had problems with micro SD cards in general with generic brands... But I generally format them in the device I'm using them with and then I have a small USB thumb drive size thing that the micro SD card goes completely inside of and windows generally mounts whatever format it might be, provided drivers are installed.
Also sorry this is so long-winded I tend to do that when I'm voice dictating...
If you have more info that might be helpful drop a line. It doesn't take much to bugger up a microSD card though. Could be as simple as damage (static or physical) when removing it from the phone and putting it in the computer. But the proximity of time when formatted to not working makes that unlikely.
And I'm rambling again.
Cheers.

I have no idea of your hardware, but 64gb is where the switch from SD-HC changed to SD-HC (technically 32 can be either, but generally 32 are HC) and older hardware that didn't explicitly support XC wouldn't work... It either doesn't see it at all or sometimes it will work until you get to 32gb, then you can't write any more data.. I have older SD readers that so both.
But any phone or reader for the last 3-5 yrs handle XC, which has a theoretical 2tb limit, SanDisk has a 400gb microSD.. Insane.
Anyway that's all moot if it used to work in your phone and reader, but just doesn't anymore. Mostly if they're pre-formatted is exFat. If you formatted in TWRP I think it probably defaults to ext4, but TWRP can do a variety of formats.
I got to say though, if you can't reformat it again and TWRP that doesn't sound promising. Perhaps there is an Android app that will let you format with more control than the default tool (I have no idea since the last phone I had with SD was a Droid running GB)
Sorry I didn't really offer a solution, I have had problems with micro SD cards in general with generic brands... But I generally format them in the device I'm using them with and then I have a small USB thumb drive size thing that the micro SD card goes completely inside of and windows generally mounts whatever format it might be, provided drivers are installed.

Well the Windows machine won't read ext4 without third-party software... But I don't see why that would keep you from formatting again. And if TWRP does the same thing, errors out, then I got think the card's had it.
If you're trying to use it in the phone you should leave it in ext4, but if you're trying to use it and windows you could try to format it exFat in TWRP.

I tried changing file system to a different type so that I could wipe it in twrp. But even after I do that, it still says it's ext4 on the pc

Nothing really.
I am curious though. Can you give me specs on the card brand/model/serial?
Also, I have had good results with UFS Explorer Recovery pulling data when nothing else will. I think there's a free trial, but you plobably have to pay for it to do anything other than verify it 'can' successfully recover, not sure, but if it is data that you need, it is good.
I only ask about the card because I found in the past I bought like three identical adata brand SD cards and one appeared to be DOA and I couldn't do anything with it and lo and behold adata had found a firmware thing that they could actually fix and they had a tool that did it.
If you want to go down a rabbit hole there is a sticky XDA thread https://forum.xda-developers.com/showthread.php?t=1355528&page=2 with various degrees of helpfulness. Its a little dated, but the ideas are sound for most of it.
Really i just googled "sd card bad after formatting twrp" and lost 2 hrs...
Let me know if you have any success, I realize this is either about data or just personal curiosity like mine... Because a probably sub $20 card is not worth this kind of investment... And if its a high end part, probably has lifetime warranty..

Did you request RMA?
https://kb.sandisk.com
I'm not sure if they are lifetime warranty or not, i have a couple ultra plus cards from Costco that were lifetime warranty.
Now on the less ethical side, if it's a current model, plckup a new one then swap/return. But obviously thats evil.

I would swap....but my data is on it. Lol. I can't delete ANYTHING on the card. Can't format, or right click a file and chose delete. It somehow got from ntfs to ext4
