S4 bootloop, E:failed to mount /system (Invalid argument) - Galaxy S 4 Mini Q&A, Help & Troubleshooting

Hello everyone,
i'm new to android devices and english is not my native language, so i'll try to explain my problem as well as i can.
the GT-I9195 won't boot, if i turn it on it freezes in the booting screen (the white logo with the model number).
so my first try was to recover it to factory settings by pressing volume up+home button+power. unfortunately this results in a red text that tells me: "E: failed to mount /system (invalid argument)", so the phone can't access the files that are needed for the recovery.
now i thought maybe kies could help me with this emergency firmware recovery but kies doesn't even recognize the phone, it stucks at trying to connect to the device.
ok at this point i knew this is getting complicated, i think the next step is trying to flash the right firmware by hand and restore the files needed for the recovery, buuut i don't know which firmware is the right one since i can't check the correct PDA/CSC/MODEM number.
now my question is how can i figure out which stock firmware is the right one, or maybe i can use some sort of costum firmware?
do i need to download any other files to make the phone work again? i ask that because when i open the odin tool there are buttons with bootloader/pda file/etc.
i hope that just somehow the files got corrupted and the intern flash memory ist still working and not damaged...
thanks in advance

[Q]+1 A100 bricked

Hello forum Seniors
I have a problem with my a100 device, I searched for days a solution, but had no success.
I bought this device with original HC and updated with ACER_AV041_A100_0.002.00_ww_GEN1 ICS rom, to this point everything working.
everything worked, boot recovery/gps/games/ics/ everything
And I used it for a long time. Then I reseted the device.
And the problem began.
the device does not turn over.
I can START fastboot, but it dont sync with pc (I got drivers instaled)
I can START recovery, but dont install nothing ( I think my recovery is damaged)
I hope that there is a solution. But have not found any yet.
my recovery does not install or mount sdcard and external sd
when I enter, I see a red triangle with a dead android
I PRESS HOME key and recovery list this
Android system recovery <3e>
Android system recovery utility
reboot system now
apply update from external storage
wipe data/factory reset
wipe cache partition
apply update from cache

There is a guide to using the EUU_SBK??? link please?????
This is my last hope.

thank all
E:/dev/block/mmcblk1 does not exist
That's recovery. Its saying recovery doesn't exist. If you can wait for a bit I'm working on fixing this but its going slow as some people aren't as clear about whats happening as you are, I was chasing a fix that didn't even need fixing, thank you. Its either something different and new, or its something thats been happening this whole time, but no one mentioned the error output aside from the update.zip failure.
I'll begin work on this new issue, and hopefully it can be fixed with the rest. The other devices seem to have recovery, however it seems it only works in CWM or TWRP, you seem to have stock recovery. I would suggest maybe trying to install CWM from HERE. Follow the instructions exactly and see if you can flash the CWM recovery and get into that. Please report back if this works or not, and what happens when you try.

thank you and sorry my inglish
Your english is fine, don't worry
Ok, so previously mmcblk0p1 was NOT found, now it IS found? Well thats better then nothing. I've seen this on another device, though it was cache that was mounting and not mounting at almost random times.
I've been tracking this as far as I can, and it appears the A100 shares an issue with the A500 (and maybe A200?) that results in a bad sector(s) and must be partitioned around. If this is the actual cause, its a hardware failure, not software, and isn't anything you did, it just died.
This explains the string of bricks that seem to occur out of nowhere.
My original method was to DD a working image to the device, completely restoring the partition with a clone of my working system, cache, recovery, etc. However if its a damaged EMMC, this will not work either. This also explains why past attempts have failed on other devices that I've tried helping with off the forum.
As I can emulate a "bricked" device, I don't have a device with this actual issue to diagnose and attempt to fix, my device doesn't have this problem. I'm not real sure I can proceed much farther until either my device does this bad sector thing, or I get my hands on a device that is already bricked and begin finding the method to repair it.
Ok..now dealing with what DOES work...
==========================================================
Android system recovery <3e>
Android system recovery utility
reboot system now
apply update from external storage
wipe data/factory reset
wipe cache partition
apply update from cache
=========================================================
have you tried selecting any of these options? Highlight with volume, and hit power to select, try from
apply update from external storage and record what it says (hopefully it just installs and your're good to go)
then
apply update from cache and again record what it says, hopefully it works fine.
then
wipe data/factory reset and again record what it says
then
wipe cache partition and record what it says
Do these in the order I mentioned, only doing the next if it fails. If it does install, don't do the rest, just report back success and what you did, in the order you did it, to get it going again.
Edit: Oh and reboot after each selection if it fails, and reboot into that menu again.
This is the problem, can't select any option
I select a option with VOLUME key, put cursor on apply updade from external storage so i hit power
And nothing happens.
If i hold power, device force power off...
Power key work perfect, only in recovery dont work...
Thank you
My friend have the same device with the same update 0.002.0_WW_GEN1, his device work normaly, when i go into recovery, I cant select any option too
I think if i reset his device, this cant boot to...i dont try it
I can upload video in youtube for you, if it help u see my case.
Ok, if power doesn't work on either device, try the home button. It's been so long since I ran stock recovery I may have gotten the buttons mixed up with CWM recovery, which uses Power as Enter. And good call on not doing anything on the other device, you never know. It shouldn't cause issues, but just in case, don't. We don't know exactly what is causing this, and if its anything like the hardbrick bug in some Samsung devices, anything can trigger it if it happens in the right order or time.

Recovery does not select options when press power /home/reset/volumes
I need a guide for use EUUs_SBK rom, I have my CPUID
And in my friend's device, how i back to original hc?
Recovery have the same problem does not intall update.zip, if I install the CWM, Can I do official update to back original state? I really need back to factory rom and recovery.
Thank you for help
If the device is having issues, I wouldn't suggest going back to HC, it can only cause more problems. If you run the official update.zip it returns back to how it came from Acer, stock recovery, locked bootloader and unrooted stock ICS.
The EUU and SBK stuff has been attempted before and failed. Its in various threads with the same bricking issues, and doesn't seem to help, or work. At this point I think NVFLash is about the only option we have left to try to bring these back from a bricked state. Sadly Acer decided to try to lock out NVFLash, so it'll take some time to see if it will work with our A100s. Vache has the NVFlash config files, so its a start, it may work it may not, however I can't test much as my device doesn't have this bricking issue, so any testing on my a100 doesn't really mean anything.
I've actually looked around locally for a bricked a100 to see if I can get and begin working on a method to repair it, but either there are none locally bricked, or none are up for sale (sent back to Acer for repair).
I'm working on it, but I have a couple roadblocks preventing me from really trying, time, and no bricked device.
Ok doing some more digging around, I've come across a thread with some posts that seem to lead me to believe that (non stock) our bootloaders don't respond to the correct SBK, mine doesn't either, and I think it's because our method for unlocking the bootloader uses the A200 bootloader, which will NOT accept the SBK, even if correct, because its wrong for that bootloader.
This leaves out NVFlash, it can't authenticate with the bootloader so it gets blocked, so while it would fix the bricks (outside of hardware failure) it's not an option for us until we find out the correct SBK for our bootloaders.
For those on stock, the update.zip failures seem to be common, however I have a few things for you to try (I think you're stock ICS right?)
download this update.zip
Its ICS 014, should work.
It seems people had issues with it working because it originally came encrypted, and had to be decrypted to work. If it wasn't, you got update.zip not found or various other errors like you did. Thanks to azmode for this.
Take your external SD card, insert it into your PC however you can, and format it FAT32. Before doing this, copy any and all files you wish to keep safe to the PC as this will erase the card completely. If your card reader has a light, wait for it to stop flashing before moving on.
Take the update.zip file you downloaded and place it on the card. Nothing else, no folders or pics or music or anything else. Again wait for the activity light to stop for a few seconds BEFORE hitting eject. Also verify the file is named update.zip nothing else, and not update.zip.zip which can sometimes happen. All lowercase letters.
Once that is done make sure the tablet is OFF, completely, not sleeping but off. Leave it off for at least 30 seconds (or if its been off the whole time don't worry about it) then insert the SD card. Hold Volume Down (closest to lock switch) then press and hold Power and hold for about 3 seconds until the text FIRST comes up, immediately release the buttons as soon as you see any text coming up.
This should once again attempt to read update.zip from the external sd card, and hopefully finds it, or gives a different error then before.
These instructions aren't much different from before, as various other users have outlined this procedure before, in particular blackshinobi who has spent alot of time on the bricked threads.
That update.zip should be decrypted which should allow it to pass the bootloader checks. I think this is where some of the issue is coming from, its that stupid bootloader encryption blocking even valid attempts to restore the tablet to working condition or updating.
If anyone is willing, could they pull their 100% official stock bootloader and stick it somewhere to play around with? Or, I suppose, someone with a 100% official stock ICS system try NVFlash on their system and see if it allows or gives permission denied? If the 100% official still denies, then our SBK generation is wrong, if it does, then its our bootloaders, and we can attempt to fastboot flash the correct bootloader to pass SBK for EUU.
Have you a alternative link? For update.zip

Did you ever have any luck getting your tablet running again?
It looks like I am having the same issue as you are. with a couple of minor variations. I've tried all the recommendations in this thread and the ones linked from here but I'm not making any progress. I fear there is nothing I can do and that the device is now a fancy brick does anyone have any other ideas on getting this fixed?
1. When I boot to recovery, get to the dead Android I see the following messages in yellow
E:Can't open /dev/block/mmcblk0p5 (No such file or directory)
E:failed to mount /cache (No such file or directory)
E:Can't mount /cache/recovery/command

E:Can't mount /cache/recovery/log

E:Can't open /dev/block/mmcblk0p5 (No such file or directory)

2. When I try to unlock the bootloader in fastboot mode (fastboot oem unlock) the screen blinks off and back on and I never get the lock.

Those errors have been identified as a dead emmc, which is currently unrecoverable. And is happening on quite a few of iconia's. This thread was prior to the devs and users finding thee issue. See all the brick threads here.

Well this isn't a forum for that device, and not being familiar with it I can only guess. mmcblk1p1 is usually external SD card, if one is inserted, remove it, if one is not, insert one. See what it does on each try. It may be internal SD card too, hard to say since I don't know that device, although a link to it's recovery.fstab would help there, or just /system/etc/vold.fstab.
Sorry,

PLEASE Help! Stuck on Startup screen after Odin

Hello all
I was updating my gf phone from rooted UVALJ4 or UVALH2 (Cant remember now, but it was an old Firmware) to root66 T999_UVUENC2 via Odin 3.09 on my Win 7 pc but after the odin install (which passed) I rebooted the phone and I got stuck on the Samsung logo on the start up screen. After about 10 mins I pulled the battery and tried to enter the Recovery mode, but nothing appears. Just a black screen.
So i Odin flashed the TWRP 2.6.3.1 to try to get to a recovery, but that didnt work. Still no Recovery.
I then used odin to flash the stock tmobile UVUENC2 4.3 firmware and it still gets stuck on the Samsung screen.
Next I tried to unbrick it via http://forum.xda-developers.com/showthread.php?t=2439367 using "SGH-T999 4.3 only Debrick Image" and reflashed the stock 4.3 rom, but that didnt work. :crying:
What can I try next? WHat should I do? I can still access download mode, thats about it.
Please help if you can.
Thx
I dont know how but I got the stock recovery to finally appear and now I get these errors (see Pic) what do these mean?
The recovery errors read: E:failed to mount /data ( Invalid argument) can't mount "/data" (invalid argument)
E: Can't mount /data/log/recovery_log.txt
again thx

Mod Please delete Thread.
Thx
In the future, try a factory reset, almost all boot hangs are solved with this. Happens because of incompatible data between versions, which would make sense condidering the jump you made. Kind of makes sense with the error message too, but I'm not 100% certain there.
Be careful with the toolkit. There is no support for it and it has bricked phones in the past.

E: fail to mount /efs, /system, /verification

One day after I charged my note 2 phone (SGH-T889), unplugged charger and started playing an app game for 5 mins. The phone suddenly crashed and began to restart nonstop but couldn't get passed the welcome screen animation. Eventually, it kept restarted and stuck in the logo screen.
I tried all the factory reset, wipe cache in recovery mode (holding the 3 buttons), taking out SD card, or all the basic stuff. The phone is not rooted at all. I even tried to install firmware through ADB (with digital signed software) but still failed to do so (even with some software to sign the zip file) because i got signature verification error. I also see failed to mount efs and system error. Also I wouldn't be able to get into recovery mode unless i hook up the usb, otherwise it will continuously fail to reboot in the logo screen.
I would like some guidance to reformat/ flash the whole phone with files linked or attached. Any official firmware version is fine for me. I only just learned ADB but I know nothing about odin. I don't want to root the phone if possible. Any help would be greatly appreciated. Thank you very much!
The stock ROM for your phone can be found here: http://www.sammobile.com/firmwares/database/SPH-L720T/
The stock ROM from sammobile is flashed via Odin as Odin is Samsung's official flashing method.

Open Odin, uncheck everything except f reset time, flash rom, when you see the word reset in the status window, remove cable from the phone, remove battery, replace battery, boot into recovery, wipe, and reboot.

Doesn't work after i put back battery in. In fact, i had trouble going to cwm after that. When I try to go to cwm, it goes to the green robot for a split second and jump back to logo screem in loop.
What happens when you put the battery back in? Does it flash stock without errors? Cwm should not be in the phone after flashing stock.

After I flashed with odin with (T889UVUCOH4_T889TMBCOH4_HOME.tar.md5), my phone is still in the download mode screen but everything is done downloading already. I unpluged usb, battery, micro SD card. When I try to reboot in recovery (I did your let go of the power button the moment the logo poped up), I am unable to do that, except I get reboot non stop and sometime I can see the green robot with the percentage bar screen. Eventually after multiple logo reboot loop, it just stuck at the screen and not do a thing.
Pretty much nothing I can do when I unplugged the phone from the USB, but when I plugged back the phone to the USB i can go to recovery mode somehow and I get all the e fail to mount errors for everything like i posted previously.
Also tried to install cwm through odin, but after odin said it pass and restarted with or without taking out the battery, I cant even go to recovery mode anymore....
omg my phone does the same thing except I cant flash at all keeps saying complete (write) operation failed. someone did resovle this please pm me or reply....
only thing that manages to connect with my phone but never complete is cwm4_fixed_for_cm7-odin.tar
I see the blue bar its complete but nothing ever happens
Sounds like there is a hardware problem with the phone. There could be a few causes but the failure to mount partitions means the memory may be damaged.

it connects only to that? so what to do @audit13
I would look around to see if I could find a cheap note 2 with a smashed screen and working motherboard to switch the parts.
If you don't want to do that, maybe ask a cell shop for a repair estimate?
The phone is not worth too much so I would not spend a lot of money fixing it.
omg are you serious so thers nothing I can do? can I show you the pictures or something what is cwm4_fixed_for_cm-7-odin.tar? why is that only working ...im broke lol!!and a noob

If you haven't figured this out yet I'll throw in my 2 cents.
Start here: http://forum.xda-developers.com/showthread.php?t=2678420
I don't know exactly what heimdall is but odin should work just fine for this. Try a few different odin versions if you have to as it has changed a lot over the years since the release of this phone.
Also make sure to uncheck reboot from odin, unplug after reflash, pull battery, then manually go to recovery immediately after flashing. If you get anywhere besides the TWRP you have to flash again.

Oh thanks for reply........... i have also make some reply in this same thread. I have also tryed some solution but i ever obtain the stock recovery. Whit odin i have also tryed to reflash some complete image founded over internet:
I have tryed to flash the stock firmware I9195XXUCPB1_I9195ITVCPB2_ITV.zip downloaded from sammobile.... after extracted the md5 it's be flashed successfully but at restart the phone stuck on recovery whit so many error E: fault to mount and can't mount etc etc.
After this on internet i have tryed a stock firmware for odin splitted in 5 file including the .pit for re-partition completely the phone. Also here all flash by odin it's be completed whitout any problems and all it's successfull but same thigs........at restart again stuck at recovery.
I don't have idea what i come do again for tryed to fix this phone If you have so other suggest......... please explain me..
*EDIT*
A strange things i have notified on this phone......... every time i put the phone in download mode and using odin and at every flash i complete in theory i can see the flash count increase right ? In this phone after this all test and tryed i do i can see the flash count blocked at zero like i never flashing nothings....... it's normal ?

Flashing Firmware Help

I'm not sure if anyone can help me-a long time ago I stupidly formatted my G6 edge using TWRP. Now that obviously wiped everything. Well I need a backup phone and I can't get odin to flash the firmware no matter what I try. I have even tried to flash some files individually either through odin or adb sideload-including the firmware-to no avail.
What Rom Ver.
I have stock 7.0 but i did a nand wipe before i put it on and my custom boot screen is still there (alienware) its bugging on diagmon random reboots and vol up, home key, power to bootloader brings up a android says updating but doesnt then goes to a fail android then to Android Recovery apply from SD card =E:failed to stat /dev/block/sdb1
E:failed to mount /sdcard (No such file or directory) --Couldn't mount /sdcard otherwise no other bugs i know of. I cant get my TWRP back it wiped it I try in ODIN but all hangs or fails with some weird asian letters after english
