I bought a new never used Tab 3 for the intended purpose of using it as a universal remote. I wanted to strip it down and started right away with installing custom recovery, or at least I tried. No matter what I did I was not able to get Odin to properly load TWRP. It went through all the steps but I was not able to get into recovery other than stock.
Fast forward to the next day, I finally get it to work and somewhere in this process I somehow deleted or unmounted (I really am not sure) my efs folder/partition. If I try to reset deleting all cache and wiping everything including pulling the battery for a few minutes and flashing the stock ROM again I get hung up at the "SAMSUNG' logo. I have tried several ROMs and even tried using Odin to flash a new pit file with I found HERE. When I load both the pit file and my ROM into Odin it eventually says 'FAIL'. I can flash ROMs all day with no issue.
I can only assume that the error I am getting in recovery that says E:failed to mount /efs (Invalid argument) is my issue.
Adb is not really an option for me since I have little to none, more like none at all knowledge of using it. I assume since I have flashed several tries that USB Debugging is not enabled anyway and isn't enabling it key to using ADB anyway?
I have been at this for 2 full days searching everywhere and trying everything I see. I am at a loss and hate to think this new Tab is already junk.
Any help would be greatly appreciated!
The EMCC or something like that requires replacement

So I should junk it then? I only paid $80 for this Tab.
One trial you may try to flash a Cyanogenmod based ROM see if it can write out the partitions else if no luck time to replace that item as mentioned
I have tried flashing CM and still the same issues.
I have since found out what my issue is (or at least 99% sure), I somehow wiped out my efs partition completely. So running a new pit file with Odin does nothing because the partition is gone.
This is fixable and easy for someone who knows shell, but I don't. So now I am trying to figure it out. It's a matter of pushing the 6 following files to the phone using the adb push [file] /sbin/ command using adb which I have done, now I need to figure out the rest.
e2fsck
mke2fs
parted
resize2fs
sdparted

you can't do that in the way you think, it requires disassembling the recovery image, making modifications and repacking then reflashing the image.
If you are using an older recovery, namely twrp, install a newer recovery , check @nels83 's thread for a "modern" twrp build.
You can also try one of my philz builds.
Being as you have been abusing Odin, you may actually have damaged your tab.
BUT if you are connecting to wifi without a problem then it's unlikely that you have damaged your efs partition. It's more likely an error with the recovery build you are using, probably in the fstab.

Hello,
i just unlocked bootloader and installed twrp and it all went fine..
until i wanted to fully wipe my device, i did this via twrp.
after 20Minuts, nothing happend, the bar was still white and gray (not even a little bit blue)
and it kept stuck on ''twrp formatting data using make_ext4fs function''.
i knew this wasn't a good idea, but i decided to turn off my phone,
and now, everytime when i turn it on on the normal way it just redirrects me to TeamWin in a bootloop.
even if i want to go to recovery mode i keep stuck in that bootloop, so there is nothing i can do right now, i only can stick at Fastboot Mode but nothing else,
Is there any way to fix this problem?
Using ASUS ZENFONE 2 551ML
I hope you did a backup of your system before? Otherwise just download the latest full image:
http://dlcdnet.asus.com/pub/ASUS/ZenFone/ZE551ML/UL-Z00A-WW-2.20.40.174-user.zip
place it on your internal sdcard (via adb push) and then flash it normally with TWRP. Please note that the procedure can take up to 30 minutes, where the formatting is the procedure taking the longest time...

but i cant use twrp on my phone because its stuck in bootloop, or what do you mean? (english not my main language)
please give me some proper step by step instructions, i would really apreciate that!
thanks anyway your awesome!
Man, I misread your post, sorry...I thought you could boot only into twrp
If you still have fastboot, why not flashing twrp 2.8.x.x?
Code:
Fastboot flash recovery nameofrecovery.img
Fastboot reboot recovery
Otherwise you could flash stock system with this guide: http://forum.xda-developers.com/zenfone2/general/guide-brick-soft-hard-bricked-zenfone-2-t3284256
It's a lot to read
wow, that is something really helpfull, there is still hope to revive my phone
i'll let you know how it turnt out xd
thanks alot!!
i fixed recovery mode, so thats already one step further. Oefff @TheSSJ thanks for the help.
But now i get some other problems, when i try to wipe my phone i get the error like ''unable to mount /data'' and ''unable to wipe dalvik''
and all other kinds of these errors, i get the same problem when i was installing rom. isn't there anything or a way to fully wipe all this **** so i can install a fresh rom.
i flashed custom rom and this is error log i get. its all full written down.

Seems you don't have a WW image installed, do you have a CN Software? Then you need another Software of course
what do you mean with ww & cn software?
sorry but im new in this.. but im really interested so can you please explain a little bit?
how can i get this other software! thanks!!!
Where did you buy your Phone? what does the packaging state? WW, CN, TW, etc? These 2 letters must be written in uppercase somewhere, then we will know which software to flash, there is a check where your phone's software is compared to the zip you are trying to flash:
assert failed: getprop ("ro.build.asus.sku") == ''WW''
Which TWRP did you flash?
ohhh yes, i do have CN software Probably, as it is buyed from china.
Where can i find this other type software?
thanks!

I think flashing will still fail though...but pls try first,maybe it'll work
i tryed it, i get the same error :/
Update: i changed from CN to WW.
Because of this i reflashed to twrp 3.0 and it works properly and now wiping shows no problem anymore.
I also got the WW ota zip but dont know how to install that.
Anyway, i tryed to install xaosp rom (even if my ota is still CN)
And it showed no problems at all!
BUT when i tryed to startup my phone it sticks with the asus logo and wont go any further, not a bootloop, it just sticks at the asus logo.
We are Always getting more and more steps further into fixing my phone, thanks for that @TheSSJ were almost there ?

You could try flashing cm13 first and then xosp:
First wipe data/cache
Then flash cm13
Boot up and hope that it works
Reboot to recovery
Wipe data/cache
Flash xosp and maybe a kernel that fits (FlareM?)
Boot to system again

sorry for the kinda late answer, but yes i followed your instructions, and it works completely, after cm13 i also immediately installed gapps.
i skipped xaosp im fine with cm13
Thanks alot @TheSSJ for all the help my phone is fully fixed now and even working faster then before its like super fast.
thanks again your great!
Hi. I've just updated CM13 to the latest nightly using TWRP, but now the system just boots into TWRP - that's whether I select boot system, recovery, or bootloader. I tried restoring from a TWRP backup or another copy of the nightlies zip - it all seems to work fine but doesn't solve the problem. I can connect to the 'recovery' device using adb but adb restart bootloader just loads TWRP again. I've tried wiping first the dalvik/cache, then everything but the internal card, then finally everything but nothing seems to work.
I did get something a little bit like this a few days ago because SuperSU was complaining that I needed to update the binary. I let it do it the way that it suggested one does when TWRP is installed and afterwards couldn't reboot into system, but after a few minutes of frustration sorted things by wiping various partitions.
I attempted to load the full system restore files (cm-13.1-ZNH2KAS29G-crackling-signed-fastboot-74bb753396.zip) using TWRP but that didn't work (I imagine because they're designed to be run via fastboot). I tried loading them via the ADB sideloader option included in TWRP but it failed after a few seconds (I think the message was 'transmitting 0.0x'
I opened that zip and copied the various files to the external card, but I then baulked at installing the image files manually because the only partition option I'm given is boot and my understanding is that each image file should go into its own partition.
The only other potentially pertinent information I can think of:
TWRP keeps reporting "E: Unable to find partition size for '/recovery'"
Has anyone got any ideas please? I had been musing that my next phone would have OTG and NFC, but I wasn't planning to upgrade just yet if I don't absolutely have to.
Have you got it fixed? And if yes - how? I am stuck in a similar situation and can't find a solution for it. Tnx in advance.
I'm currently running my OP3 on Resurrection Remix 5.7.4 (MM 6.01), the phone has the latest version of TWRP and I've flashed other ROMs in the past without any issue
RR has proven to be quite unstable for me, the system UI keeps crashing, which renders the phone unusable until after a reboot so I wanted to flash Freedom OS as that worked quite well for me previously. When I tried to flash the ROM in TWRP the ROM seemed to flash successfully but when I rebooted, only the boot logo showed and then the screen went black and the phone refused to respond at all for about two hours, after that exactly the same thing happened. I managed to boot into recovery and tried flashing a different ROM but the result was the same every time, the only way to get the phone to work normally was to flash RR again/restore from a Nandroid backup, either way, the result is the same, I'm stuck on an unstable ROM and I don't know why, the last time I flashed these ROMs they worked fine, I followed all of the instructions for flashing said ROMs to the letter, I have the latest version of TWRP, etc.
Also it seems TWRP can't mount /system, in TWRP under "mount", system is unchecked, I checked it and tried again but found that whenever I rebooted the phone or attempted to flash a new ROM, it would always uncheck itself and flashing the ROM would fail, however strangely flashing the same version of RR was always successful. Is this why the flashing keeps failing and does anyone know what the problem could be?
Thanks!

Go into your bootloader and format system, cache, and userdata (This will wipe EVERYTHING so be sure to backup). Then latest official flash stock rom and reboot. This should fix it. If this helped hit thanks!

Bootloader? There is no option in the bootloader to delete everything as far as I can see, do you mean in recovery? And if I wipe everything off the phone, how do I get the stock ROM onto the phone to flash it? When you say wipe userdata do you mean wipe internal storage or am I misunderstanding and you're telling me to wipe the usual dalvik, cache and data as you would for a normal clean flash?

No, go into fastboot and plug into pc. Open cmd and type "fastboot format userdata" "fastboot format cache" "fastboot format system"

Okay, thanks, and then what? Do I flash TWRP then push the stock ROM to the phone and flash that? And exactly how do I do that?

You just go into twrp (no need to reflash) then adb sideload oxygen os

Thank you, I am now running OOS, hopefully everything else will go smoothly now, planning to go back to FOS again
I didn't even have to use the fastboot commands to format, just sideloading the OOS file wiped everything anyway
Turns out the issue isn't actually fixed, "system" still appears unchecked in TWRP. Could the fact that I didn't actually format everything first have made a difference, given everything was wiped in the process anyway?
Looks like I'm going to be living the sideloading life...
Edit: Sideloading freedom OS failed, ended up having to restore from my TWRP backup. I don't know what I'm going to do, my main reason for using custom ROMs is installing a black theme, and OOS doesn't support Layers or Substratum fully so I can't stay on that
Is the thing that says "mount system as read-only" enabled in the mounts menu? /System isn't ever mounted when TWRP starts, you have to manually mount it, but as long as the updater-script tells /system to mount, it will. However, if that option to make it read-only is enabled, then nothing will ever write to /system. Last resort is deleting the .twrps file from /sdcard/TWRP folder to remove current TWRP preferences and then when you boot into TWRP, that first screen has the swiper to allow modifications, and you'll swipe that

It isn't set to read only, I have tried updating and resetting TWRP but nothing has helped, in fact it's got worse, I managed to sideload OOS but my attempted install of FOS failed so I tried to restore from a backup and that also failed, something which didn't happen back when I was on RR.

Which version of TWRP are you running? The official 3.1.0-0 is good for OOS and OOS based ROMs only. Try eng.stk's version.
Use the latest eng-stk twrp.
https://forum.xda-developers.com/devdb/project/?id=15934#downloads
In recovery go to Wipe > Format data (this will wipe ALL in youre phone).
It's youre Data in F2FS? If yes you must change it to ext4, in recovery Wipe > Change file system. Reboot recovery. Check if it's changed.
Reboot to Bootloader (Fastboot). From PC reflash recovery.
Now copy Oos rom to the phone memory. Flash rom. Reflash recovery (the rom will overwrite the recovery). Reboot to recovery to see if it works. If not do it again.
I sugest to NOT restore old data. This way you'll have all new in youre phone.

Help! I attempted to do this and the process failed, I didn't manage to wipe data because "/data could not be mounted as device or resource is busy"
Edit: Device now has nothing but TWRP and fastboot, no OS, no ADB, no data, no internal storage
If you can reflash twrp from PC. If not reflash recovery from twrp recovery : Instal > Image > Select Recovery (you must have TWRP.img in youre phone memory )
I managed to get hold of a few factory images and attempted to flash system.img through fastboot, resulting error was
"target reported max download size of 536,870,912 bytes" (system image is 3080 MB)

I reflashed the modified TWRP successfully. The second suggestion wouldn't have worked, given my phone has no internal storage
You can't see internal storage because of the recovery does not work write.
If you have a working recovery you can do all you want.

The recovery was working at this point, the issue turned out to be the data partition, system was formatted to ext4 but I didn't realise data was in f2fs which caused the problem in the first place. I formatted to ext4 and everything worked, I was able to install paranoid android and everything worked...
...until I flashed the wrong firmware and now I've hard bricked it! I'm going to try the hard brick toolkit
Edit: After 12 hours of being an unresponsive brick, the phone suddenly booted, system doesn't work but it has recovery. Unfortunately I seem to be back to square one, if I try to flash something it appears to succeed but then the phone doesn't boot up into system
So I am now back to the original issue of system not mounting, in terminal if I type "mount /system" I get following error:
"mounting /dev/block/sde20 on /system failed: Device or resource is busy"
Anyone know how to solve this?
I formatted everything, reflashed recovery and tried to flash OOS, got following error:
Code:
[FONT="Courier New"]"This package is for OnePlus3 devices, this is a oneplus3t" (it isn't)
"Updater process ended with ERROR: 7
Error installing zip file /sdcard/OOS3.2.6.zip" [/FONT]
Issue was "solved" by flashing PA, GApps and the correct firmware
Hopefully that's the end of all this drama, thanks to everyone for their suggestions
Hi, I'm pretty new at rooting and I seem to have a similar error. I'm getting the "can't mount /system" error in TWRP. I am able to boot into OOS 4.1.3 and run the nandroid backup but, I keep getting the same error and am unable to select "system" when choosing the mount option in TWRP.
Do I need to have all partitions in f2fs? My system partition is in ext4. Is this what solved your issue?
It seems my phone is functional even with the error active but, I've been trying to get systemless SuperSU and MagiskHide working and I think that's what is preventing me from doing so.
I have a FTV 2 that can get into TWRP but can't boot up normally. I've tried flashing prerooted images, unbrick script, and wiping everything. I am stuck.
In TWRP I keep getting unable to mount Cache Invalid Argument. When trying to flash a pre-rooted image, it just hangs forever on copying system image.
Is there anything I can do? If I need to get a replacement device from Amazon, can I remove TWRP, even if it won't boot?

Edit:
I followed your steps and made it to work.
Thank you
Thank you for responding rbox.
I already tried the cache clearing steps you mentioned, and just tried it again just in case. I still get the hang on "copying system image" when trying to flash a prerooted image, and I see "failed to mount '/cache' (invalid argument)".
At this point all I want to do is remove TWRP. Can I do that from the terminal in TWRP?
