Wiped T310, no OS, unable to mount internal SD - Galaxy Tab 3 Q&A, Help & Troubleshooting

Prior to today, I had not installed TWRP or rooted my T310 device. I believed I followed the instructions to root my device correctly (found here). Going through TWRP, I rebooted the system to install the Superuser package. I then rebooted the system, loaded up TWRP, and began to do a system wipe (followed instructions found here) to prep the flash of the rom and gapps.
I selected the following partitions to wipe: Dalvik cache, system, data and data. The instructions werent clear, so I checked both 'data' boxes.
After the wipe executed, I went to flash the rom and GAPPS I loaded to the internal sd card aaaaand... there were no .zip files. Crap. I went to reboot TWRP and it alerted me that my device does not appear to be rooted. Double crap. Not panicking, I went to mount and tried to see if I could mount the internet SD card to my device. Nothing. Windows now shows a 'Samsung_Android' device but it is listed under 'unspecified'. Reloading the drivers have done no good.
I'm guessing SuperUSer was never installed correctly *or* I did something during the reset.
I, of course, did not perform a backup prior to all of these. I have rooted my devices multiple times and it was always a breeze so why backup now? Weell...
So now I'm sitting here with a nonSU device, with no OS, no backup, and I'm unable to connect my device to Windows. Outside of loading a rom from an external SD Card, what options do I have?

You can either download the whole firmware and use Odin to flash or get adb setup and push a rom zip to the internal card using adb.

hi,
you will need a microsd card 32gb and properly formatted that comes with a card reader for your pc.
download your rom and get it onto the card, insert the card into your device
boot to twrp, and flash,
now, if twrp still spits the no os message at you, which is an issue with twrp,
you next need to go to your wipe options, select advanced and do a full data format/wipe,
NOT SYSTEM, DATA. meaning /data and /data/media. when that completes you should be sorted
but expect your initial boot of the new rom to take a little longer.
never wipe system with twrp. the rom's updater-script will manage that function.

Thank you both. I lost my SD cards and card reader in a move so while that orders, I will attempt to utilize ADB. I'm pretty green but I'm certain there are guides out there..

I'm having a hell of a time getting the rom to install from the SD card. I believe I am not formatting the card correctly. Is there a guide on how to do so? I have a primary partition in SD in FAT32 and the other partition as EXT4 but no luck. Any help is appreciated.

hi,
your external sdcard should be formatted as single partition fat32 unaligned,
if you running windows, use bootice, look it up
On linux , gparted may give you issues, if so, on debian at least there is another better utility
though the name escapes me at the moment, disk manager i think.

Well I was able to find a good stock firmware download, flashed that via Odin and I'm back to square 1. I am going to forego the external SD route. Perhaps too technical for me or some other hang up is abound but I am leaving that method alone for now. Thank you for your help : )

double check your partitions, make sure you have FAT32 + EXT3 @512mb then flash the chosen rom again, this is your best chance.
go with my rom, linked through my signature, the update will wipe the Cache + dalvik cache but keep all of you personal data and apps.

How do i check the partitions? Cant boot so can`t see them that way and haven't got card reader or anything. Im sure its got something to do with partition. Does this seem like it is causing the problem?
Any help appreciated.
bump, need help
have you wiped everything before flash?
I wiped with rom manager after downloading rom. Not sure of all the custom recovery options as rom manager usually does it all for you. Not sure if i should wipe date, cache etc, will this wipe my backups? Tried removing sd card but wont boot, not even sure how I would get another custom rom on sd card so i could flash that. I have both defrost 2.4a and opendesire aswell as a nandroid backup on my sd card but can't get these to boot either
Must be something to do with the sd card partition. Everything I try I get the message
E:Can`t mount/dev/block/mmcblk0p2(file exists)
error mounting sd/ext/!
Don't know what this means but think its causing the problem.
perhaps a bad sector on the SD?
try backing up everything on the SD, format it again & try the roms one by one to see which possible causes the issue
U need to try an alternative recovery.
Try using unrevoked, and flash and different recovery.
Sounds like the fake flash recovery u got with rom manager Isn't clearing ur partitions.

in Windows XP Disk Management, right-click the existing partition,
and click delete, that will leave the whole card as unallocated space. Then
right-click on the unallocated space, and click new partition.
edit : or install http://www.sdcard.org/consumers/formatter/sdfv2000.zip
free SD partitioner
in disk management it only shows the size as 3.18gb, I made the partition through rom manager which I think formats it in linux which windows doesn't recognise.
Taking the Sd card out gets in onto the animation screen, so a little further, but still doesn't boot. Very frustrating. \\\\\any more help appreciated.
Flash a ROM that doesn't use Apps2SD.
can you link one for me pal, ripping my hair out here, lol. By the way how do you do full wipe in custom recovery ie data, cache, is that it?
edit. Don't matter. Sorted. Copied an earlier backup of sd card onto spare sd card and did a recovery. Still need to know how to remove the partition from other sd card using windows.
This was definitely the problem and won't be using rom manager to do another partition.
If someone does know how to remove partitions using rom manager from sd card via windows then would appreciate it if you would let me know...
Stock rooted ROM: http://forum.xda-developers.com/showthread.php?t=694564
Full wipe can be done using the "wipe data/factory reset" option in ClockworkMod Recovery.
To get rid of the ext Partition get gparted or something like that. Normal Windows cant see ext partitions because its a Linux filesystem. You can also take a Linux live cd.
Can't you just take ROM Manager and partition your SD card again? Swap 0/Ext 0/FAT 32 All
It looks like something isnt ok with the partitions so i would recommend to delete all partitions and make them new i also had a problem once with my sd card but after deleting all partitions and repartition it everything was ok again.

[Q] Using factory restore and erasing sd card contents within a custom rom

I am curious what the results will be if I use the factory restore within a custom rom . I'm currently running AOKP M5.1 . I am wondering if there are any unsightly ramifications to booting into TWRP and doing a factory restore and erasing the SD card contents? I would like to do this to free up as much space as possible and remove the left over remnants of over 20 flashes and a plethora of app installs. One question I have is will TWRP wipe its own directories?
Would this be better from a stock perspective? The only time I wiped my SD card I was on stock and I really don't care to experience any directory malfunctions or card mounting issues. Doing this within a custom rom will my device still know its a kindle lol?
Edit: I know that this will not restore to 6.3.1 I'm just looking to run AOKP in a clean fresh environment including the SD card thanks for any input

You cannot wipe recovery from inside recovery, only the TWRP backups on your sdcard will be lost. The sdcard is on its own partition apart from recovery and system files.
Backups are backed up on my pc also the only time I have used factory restore is when I was going to flash something new. The idea of this seems simple I just don't want it to be problematic since I won't be doing a new flash.

Factory data reset from a ROM will wipe the /data partition. It's effectively the same as "Wipe -> Factory Reset" from TWRP.
On the other hand, if you do the equivalent from the stock software, it too will wipe the /data partition, but it will also take the SD Card contents along with it. I learned this the hard way.

I would like to flush the SD for a clean start music video and apps can all be restored before I stick both feet in I want to make sure that it just gives me the spring cleaning that I'm looking for
Well here's what I decided to do I figured since I had a working rom on I would do it all from the factory restore in the rom. So I clicked factory restore and erase SD card after rebooting it prompted me to set up my Google account. After it restored my account and all my apps downloaded and installed, I moved some files to my SD that I wanted back on and did a backup through twrp. All said and done I was very excited to see that I had 4 gigs of remaining space on my SD card so I managed to clear out 2 gigs of excess clutter from what I have done on my kindle. The only downside I have noticed so far is when hooking my kindle to my computer it shows G: removable disk . ADB drivers are good but its no longer listed as kindle under my computer which isn't the first time I've seen this.The way I figure no big deal adb works and I can access my SD card contents on my computer how its listed is irrelevant.
Drivers driver drivers windows sucks lol at this point they are functioning so I will not be trying to reinstall them. Later I will try another restore and wipe my SD through twrp to see if that changes probably won't make a difference I'm just gonna do it for kicks and giggles
On a device that only has 5 gigs of storage regaining 2 more gigs of play room is substantial. There was more clutter than what I anticipated I was only hoping for a half a gig and I'm certainly thrilled by 2

[Q] Can I access storage memory from CWM?

I have a Galaxy Nexus that won't boot. It goes through a boot loop. I've tried everything to try and get it working. I've wiped data/factory reset, I've formatted system and re-flashed ROMs that were already on my phone, I've tried restoring backups from several nandroid backups. It never gets past the initial Google splash screen with the unlock symbol.
I'm going to send it in for service, but I'm wondering if there's a way to try to access the flash memory to copy all the data to my computer? I've stupidly done tons of regular backups (Titanium, SMS, nandroid) to my flash memory on my phone, but never backed it up to my PC. I can see the directory structure through CWM 5.5.0.2, but I can't mount it as a USB storage device from CWM and I assume I actually have to be booted up to use ADB.
Any suggestions?

You should be able to do adb with the device in recovery mode. I'd recommend doing something like
Code:
> adb pull /data/media sdcard
This will copy the entire contents of the pretend SDcard on the phone (/data/media) onto a new folder on your computer called "sdcard".
I don't think there's a way to access the internal memory through CWM. For CWM to do that, is that to unmount that partition, and it cannot unmount data (where the sd-cad resides) as android wouldn't run without the /data partition, or so I've heard.
Feel free to correct me if I'm wrong.

Recovery is not Android, it will run fine without the /data partition mounted (though there isn't a whole lot it would be able to do then, since that's where all your flashable goodies would reside). CWM accesses internal storage all day long when you're flashing ROMs and kernels and whatnot.
Thanks! I assumed ADB wouldn't work in recovery because I tried it quickly on a PC that didn't have the drivers installed. I plugged in it on my upstairs PC and I'm doing a very lengthy adb pull as I type this. Thanks!

stuck in recovery now what?

I updated clockworkmod recovery through rom manager. Rom manager said the install was successful. So then I boot into the recovery to flash the cyanogenmod 10 preview build. I do all my wipes data, cash, exe. Then I go to install the rom and I realize now with the new recovery I can’t install/restore anything from /extsdcard (external storage). It only has the option to install/restore from /sdcard (internal storeage) which would be fine except all my roms/backups are on my micro sdcard (external storage). I have already wiped everything so now I can’t boot my phone to fix it. Is there a way to install the old recovery after I have wiped everything. I was thinking about using Odin to flash the old recovery in download mode again (like I did when rooting) but I am not sure if this is ok to do. I tried mounting the internal storage to my pc to copy the files I need from my computer to my phone. When I plugged it in the box in the bottom right popped up and said installing drivers and they were successful but when I try mounting (anything) the computer does not recognize it. So I can’t transfer the files. Would someone who knows more than me give some advice please?

While youre in recovery, can you mount through the mounts and storage option? Im not on the recovery you are talking about but if you can mount it you can throw the rom on that way. If you cant do that you should be able to just boot up the rom thats currently on it and mount it that way. Just because you wiped everything doesnt mean that it wont boot up, it just cleared all of the data. It should load up with your previous rom.
Thank you very much. It gave me more insight on what was going on. I have my phone back up and working. I was able to flash the old recovery with odin and i hope this information will help someone else in future as well.

Stock recovery wipes everything but TWRP preserves the "virtual" sdcard. There might (or might not) be some advanced option in TWRP to wipe the virtual sdcard, never looked.
Twrp has the wipe option, I knew that already. I wanted to find a way to use it and still be able to flash a rom. In any case I figured out how to transfer a file to the device with the ADB push command after getting adb to recognize the nexus. Will attempt all this in a couple of days.

I guess I don't understand what you mean then as by default twrp doesn't reset your virtual sdcard for a wipe, so whichever ROM update.zip files you had on the virtual sdcard would survive a wipe in twrp, so there would be no reason to copy them back over.
I guess maybe your question had nothing to do with wipe, and you were really asking how to transfer a custom ROM install file to the tablet so twrp can install it. You can do that using adb or mtp or just download the file using the browser on the tablet.
In advanced wipe there is a box for internal storage... and TWRP supports OTG so you can connect a flash drive formated to FAT32 that contains the Zip you wan't to flash and flash it like any other file.

This is what I mean. My virtual SD Card (data/media) is bloated with files I want to get rid of. So I wanted to wipe internal storage to clear all files and reinstall a rom. Using ADB or USB-OTG as iamezio says, I can transfer a rom zip back to the internal storage after wiping it to be able to install a rom. When I first made this post I wasn't sure how to do this.

Well, when you do a wipe from twrp, it is just removing all the files using a delete operation, which you can also do yourself.
The part of your question that seemed pertinent to me is you wanted TWRP to see your ROM file, which is the same question one would have if they asked how do I install a ROM.

twrp will wipe you internal storage with that option you saw in advanced settings. i actually did that one day by mistake and had to sideload the files to get back up and running. if that's what you are ready for, then go for it, it'll do it...
