Hi!
is there any custom revcovery, which has the option to boot (not to install) Android completely from SD card or USB?
I'm aware, that SD or USB would be a pain due to low transfer speed, and also, that you cannot just copy a firmware image files to sd card.
So, search didn't show any helpfull results, except "https://www.xda-developers.com/rom-external-sd-card-guide/" (which seems to work for some devices with dead emmc, only)
Any idea?

I am trying to Flash my G Tablet with a new ROM. When I view the existing files on my G Tablet using the resident file explorer two SD cards show up, SD and SD2 but there is no SD card installed in the slot. The reason this relates to my attempt at flashing the ROM is the mystery SD card is the only thing my laptop shows when tethered using the USB cord.
Can I delete these mystery SD cards without any harm?
If I do delete them, will my laptop then be able to get to the Root folder so I can transfer the Clockwork Mod and TnT Lite files?
Hmmmm interesting i have never heard of that problem (not that its abnormal).Well in the viewsonic g tablet there is an internal sdcard, but you mention a SD card 2. I would reccomend NVFlashing because this may just be a glitch and it will restore your tablet back to normal. And as a plus, it will be very helpful learning how to NVflash your device because it comes in handy very often. Hope it works
I have a 4gig thumbdrive I tote around with a persistent version of ubuntu and some other utilities, like ultimate boot cd. Since I always have my phone, I figured why not just use it instead of carrying the thumbdrive.
I have been trying to install the boot installer on my phone's sd card so I could just boot a PC with the phone. The trouble is that if I install the thumbdrive boot files on the external micro sd card there seems to be no way to boot a pc from that drive. If you goto disk drive mode and boot the PC, it only wants to boot to the first USB device, i.e. the internal SD card. I tried the multimount usb app, but that did not help in mounting just the external SD card.
I have installed the boot files on the internal SD card and successfully booted the PC with it, but once the phone is restarted it decides there is something wrong with the internal SD card and it reformats it.
Has anyone tried to use their phone as their PC boot thumbdrive?
I have tried the YUMI and the old fashion single boot on pendrivelinux.com. It matters not whether I select persistent mode.
Hi, I've installed CM7 on my SD card so that when I switch on my NT16 with the SD card it boots to CM7 and Android 3.7.3. I've extended the 4th partition on the SD card to make use of the card's full capacity but I can't seem to put any files onto this partition.
When I explore the SD card it just shows less than 200MB. When I connect the NT16 with the SD card to my laptop it shows two removable disks but when I click either it says to insert a removable disk.
Any ideas as to how I can put files onto my SD card?
Gotta put it into USB mode.
Only way I know how on my 8GB NT is to:
1) Boot from the CM7 SD card.
2) Once running CM7, connect cable to PC.
3) Android bot will appear on screen with a button that you can click to get it into USB mode.
4) Only after you click will both drives (internal and SD card) appear on the PC.
i tried the sdcard way for roms but i just can't wrap my head around how to get to the fourth partition while using the rom. if u browse to it using a file explorer like root explorer it will only display the rom partition rather than the user data partition.
so the question is: how to get the user data partition to show while using the rom...
Thank you!
When i have my SD installed on my phone and try to enter on recovery mode (TWRP) it gets stuck on TWRP Boot logo, i need to pull my battery to shutdown the phone.
if i remove the SDCard and try to boot into recovery it works without any problem.
i installed TWRP through AutoRec from Play Store.
Now i'm on marshamallow and i use the SD Card as internal memory, so i dont know if i can remove it without cause any problems just to use TWRP.

When you decide to make your sd card "Adoptable (internal) Storage" your phone not only incorporates the card as internal, but it also ENCRYPTS your sd card. Now the only device that will read your card is your phone. Try and load it on a desktop or your laptop and it won't even recognize your card. Because it encrypts your SD CARD, TWRP cannot see your card and thus gets stuck on the TEAMWIN screen when booting into recovery. When you remove the card and reboot into recovery, then TWRP works again. How I fixed it is to go to storage, and settings and change the card back to "Transportable (extrnal) Storage." The phone will reformat your card again (thus erasing everything on the card) and make it external and able to be read from any device (laptop, desktop, etc.). This will also allow TWRP to see the card again and will not freeze on TEAMWIN screen when booting into recovery. Also, if you revert the sd card back to Transportable Storage, your phone will "remember" that you had an SD CARD assigned to Adoptable Storage. You need to click on that SD CARD and choose "FORGET" card. this will remove that SD CARD and assign your newly reformatted Transportable SD CARD as the only card on your phone. If you don't do this "FORGET" step, your camera, your gallery will force close everytime you try to open it because it is looking for the Adoptable SD CARD that you got rid of yet your phone still thinks it exists. Once you "FORGET" that SD CARD, your phone will function properly. I learned all this the hard way and hours and hours of reading.
TWRP - Does hybrid partitioning possible after SD Card reverting Int->Ext allocation?

Thanks a lot texasjmzmd for your diagnostic and fix, very helpful! TWRP documentation says nothing about possible hybrid partitioning Int+Ext to extend Internal memory keeping External capacity, except the menu proposing to allocate some memory (with no precision about memory units bytes/kbytes/mbytes). Some enlightment about that issue would be more than welcome : a link to documentation or any related post.
Hi P9000 users!
I had now time to test some stuff with my P9000. One question: I inserted a Sandisk 128 GB SDXC Card (UHS) and formatted as internal Storage (want to move apps). Worked fine for the Phone and i was able to move apps to the SD. But after connecting Phone to USB (via MTP & unlocked phone) it only shows 32 GB internal SD. Also via File Explorer app on the phone i cannot find the external SD or mountpoint....
Anyone with same issue? I also changed connection-type to USB and then my OS (Win 10) does not open phone file system at all.
thx and br

We did an article about the SD card memory management in Marshmallow a while ago on the XDA portal that explains this, I'd suggest googling for it as I can't remember the title.
Edit: Something to do with the SD card being formatted as Ext4 (linux file system standard these days) and Windows not supporting Ext4 filesystems.
Thx for reply, so i am afraid its related to Android 6 default behaviour. So if SD is formatted as internal storage you cannot access via USB from PC or managing files on it via file browser app? Thats really disappointing for me since it then switches SD card to enhanced app storage only, useless for image, videos, music etc. Of course i can format as portable SD, but then no movement of apps are possible (via root its maybe the only option).
In SD portable mode, i also had issue that SD cards randomly disconnects and one time it even needed to be reformatted. Have read about that in another thread, that this is related to physical sd mount... will see to fix this with some tape :/ (gives me not a good feeling here)

Update: checked some forums and blogs, seems not to be android 6 default behavior that you completely cannot access the files on adopted SD-card anymore. after adopting as internal storage... anyone could also reproduce this? I will try doing factory reset with SD-Card inserted..
