Not working odin not reading the device and sideload keep aborting install. how to load cwm recovery?
[Galaxy S III General] nk33:
You have to install latest samsung drivers on pc. Also try different versions of Odin - there is always one that works better on one device than another
[Galaxy S III General] DaGWaR:
yea downloaded drivers and search for odin for the 9300 did not work.

I managed to hide the problem by changing the IMEI mask using an xposed module and because of that I was able to make an exchange, switch on a Galaxy S6 Flat SM-G920I.

Unrooted GT-I930 E:failed to mount /efs, /system etc

Okay, I have the same problem and am looking for a different solution than the ones already mentioned. My unrooted, untampered-with S3 (GT-I9300) randomly got stuck in a boot loop yesterday and I haven't been able to fix it yet. I can get to the Recovery page and get the same E: failed to mount notifications (failed to mount /efs (no such file or directory); failed to mount /system (no such file or directory); failed to mount /cache (no such file or directory); can't mount /cache/recovery/last-recovery; failed to mount /data; et cetera). I first tried wiping the cache partition and tried to reboot the system; when that didn't work, I did a factory reset and tried to reboot - it's still not working. I've been charging my batteries with an external charger for a couple weeks now because my phone's USB port is faulty (not connecting well, I think - when I push the USB-charger all the way in and hold it in a certain way, it charges, but it stops doing so as soon as I let go), so I don't think trying Odin is my best/easiest option right now.

I can connect my external SD-card card to my computer fine, so I'm downloading the stock ROM atm and will try to c/p it to the SD-card. Am I right in assuming I need to put it in the phone, enter Recovery mode and then try '"Apply update from external storage"?

Is there anything else I should do? Any options that don't involve connecting the phone to the computer?
[Galaxy S III General] Mosiur420:
Follow this. It should help. I discovered it from various source.

How to Solve can mount /efs

1.	Download any recovery twrp or cwm recovery on your phone.

2.	If ddi: mmc_read fail show up then Select T flash on odin 3.09 and install recovery on memory card.

3.	For my case, I couldn’t flash stock firmware with odin. SO, i flushed twrp on my microsd card. If you having firmware problem go here my another post --- ( https://xdaforums.com/note-4-tmobil...-error-fix-t3434335/post72354317#post72354317 ) You can flash firmware through twrp. Forget about odin once you have twrp. For me odin still doesnt work.

4.	I tried with everything online. Didn’t work.

5.	Now do the steps I Say to remove this can mount /efs error.

6.	Once you installed recovery mode, setup adb from online.

7.	Open adb folder in your computer and press shift and click the right side of mouse. There you will see open command prompt here.

8.	Click on it

9.	Type adv devices

10.	If it says some random number and digits and recovery on other side then you are in the right track.

11.	If it doesn’t say this then install your drivers

12.	Now type these commands

adb shell

su

cd /dev/block/platform

ls

cd dw_mmc (for me it was dw.msdcc.1 something like that, so don’t forget to change it on here )

ls

cd by-name

ll ( for me this didn’t work so I put “ls -l”)

mke2fs /dev/block/.....(lastly what ever says cant mount /efs, system, catch just put the code in here. Code should be like mmcblk0p13. Not same for everyone)

mount -w -t ext4 /dev/block/.....(paste the same could here too)

(If you have multiple problem like system, catch and efs cant mount. Do one at a time. )

reboot

Hope this help. like share

watch this video it will help.

Hi can anyone plz help with my EFS error I been asking in other forums but I'm not getting any helpful responses so I'm asking here here's where I am with my progress...

I hope you can help......I have this ERROR & I tried several ways to fix it Running the EFS Professional.exe as Administrator.....& it keeps telling me I don't have enough storage & I deleted a bunch of apps & data from phone /sd but I keep getting this error unable to back up certain partitions

[Galaxy S III General] srdryl:
no I sure didn't......I unrooted it & returned it & got a new device.
[Galaxy S III General] mattman1978:
Fixed my efs. I had a backup, but the backup didn't "fix" it. TWRP wouldn't load it. Can't remember the error. So, I used Odin to DELETE the EFS and then re-loaded it using TWRP backup. Worked like a charm! I believe it had something to do with permissions. Oh, I clicked format as well in Odin. Samsung galaxy grand prime. I'm sure if you have a backup, the same would probably work on any Samsung phone. MUST HAVE BACKUP!

[Galaxy S III General] perwhis:
Fail to mount all partitions...

I have the same, but likely a more serious problem, as all partitions fail to mount and both external and internal storage report 0 MB. I am not able to make TWRP "see" the internal storage so that I can reformat it, nor can Odin write to the phone as it seems. I have tried a downloaded PIT-file to re-partition, but it seems re-partitioning is not possible in the current state of the phone. I do not think it is a hardware error. My guess is that the partition table has been lost? Are there any ideas how to recover the phone, so that Odin can be used to flash a stock rom? The suggested commands does not seem to work for me. (I have used LineageOS 13, Marshmallow, for four months until this happened today.)

P.S. This is my first post, and I am not 100% sure about the protocols, i.e. if I should start a new thread or not, but it seemed to me this thread may have the solution as the problem is very similar, so I posted it here. Sorry if this is not the correct thing to do.
[Galaxy S III General] ZRK_NanDRD:
I had this problem & pretty much tried most of what you guys tried, but to my surprise...it wasn't that hard to fix this. This is what I did to recovery my device.

On TWRP > WIPE > FORMAT DATA then type yes

> = click

After doing this please DO NOT REBOOT device, 1st flash a custom rom from TWRP then you can proceed to do whatever you want. ;)

Hi everyone,i am asking for your help i am noob at this. So i wanted to install a custom rom on my s9+ (Pixle Expirience),after using the rom i installed a random android pie kernel,then the rom woudnt boot.So i installed a normal custom rom that i knew it worked.I flash that but i didint have mobile data and i coudnt see my IMEI and my flight mode was plain blue instead of gray(but my wifi worked like everything elese).Then i installed stock firmware via odin,still nothing.

Then i panic and found some software which with u can insert your IMEI,but i have accidentally wiped my efs.So now when i install firmware it is stuck at samsung logo,and in TWRP it says failed to mount /efs Invalid argument.So i ask u if u can guide me on what to do and how to get efs file.Your help is appreciated.Thank you.

HI GUYS!

I have a problem with my Samsung S9+ , while it stopped at a sudden and started to have a loop restart and then i got to the recovery mode i did wipe cache on the beginning and restarted but it went for loop restart, then i did factory reset and again loop start .. so then i went to the bootloader to install a firmware via Odin3 i did it and then when it finises and the phone reboot it come back to the recovery mode and show on the screen down that "failed to mount/data"(invalid argument) failed to resizing-data ..

knowing that i cannot go on the phone to do ADB the phone is only loop restarting ..

please guys anyone can help me in that ??
[Galaxy S III General] nk33:
mate you have to put it in Download Mode to use ODIN - make sure you download the official latest Samsung firmware for your exact device and it will work 10000%... downside is you will be on crappy official laggy buggy firmware - though for the S9 will be ok as its quite powerful.

...unless you have an issue with your hardware - then there wont be a fix apart from a repair of the hardware
[Galaxy S III General] ahmedhkad:
I did install a firmware from sammobile.com: G965USQS9FUC2_G965UOYN9FUC2_TMB it gave me PASS on the end and it was rebooting after installing ,, then it gives me the recovery mode screen and it shows "failed to mount /Data(Invalid argument) failed the resizing-data .. so please is there any other solution than Odin3 Or the Factory Reset ?
[Galaxy S III General] nk33:
Odin 3 is the very last resort solution - if this doesnt work then as far as i know there is no way.

try Odin again, use a different usb cable - make surd it is fully finished before you reboot it - when it reboots it should boot straight into the samsung phone setup

use the guide below - firmware must be exact - be careful

I left my phone now without charging so it went off... As soon as I plugged the charger it went on Although I didn't turn it on , it went on once i plugged the charger and again loop rebooting .. do you think it is hardware issue ?

If its boot-looping that usually means you have the wrong rom

Hello everyone,

I bricked my phone by flashing a bad firmware, with the help of @512 I was able to bring it back to life. But after flashing with an official rom everything works fine except the imei is null, when I try to do a factory reset data it indicates that there is a failure to mount the efs file on the system. See attached photos.

Ps: how and which software can I use to restore it (efs file) to what it seems the galaxy a21 cannot be rooted.

Hello guys. I have this Amaway A725 Tablet which I have rooted a month before. I tried to change the boot animation, which was when my tablet started rebooting and stuck at boot screen.

I fear that I would have bricked my tablet. Please help me.

I don't know the device, but I don't think you can brick a device just by changing the boot animation.

Can you reboot in recovery? If so, do a full wipe

A factory reset would not affect the boot animation in any way,shape, or form.

Reset the kernel info of similar hardware.

You can not recompile kernel and all related firmware just for the sake of one piece. If you are really serious about it, then you should search device with similar hardware configuration, I mean a clone of your device with genuine specifications. Then you can flash the files into your hardware.

Do you really think, you can re write every technical information and support drivers otherwise?
