ODIN mmc_read fail, but MMC is alive! - Galaxy S 4 Mini Q&A, Help & Troubleshooting

I've acquired an S4 Mini i9195 that is "soft bricked" and worth repairing.
It sticks at the "Samsung S4 Mini" (white on black) screen, but is happy to boot into ODIN or recovery partition.
I tried to flash a new recovery using heimdall; it aborts with "mmc_read fail", even if I specify a PIT file. I also attempted the --repartition from a full backup, which also fails with the same message (followed by "SECURE CHECK FAIL: PIT")
It's sensible to presume the "mmc_read fail" messages aren't normal and the device is clearly telling me what the problem is .
Except the stock recovery partition boots can and can even wipe and reformat /data and /cache. So the MMC seems fine here and it's strange it would be reliable at one thing, but totally broken for another?
What could I try next so I can start flashing the recovery etc.?
Thanks

What happens if you try to flash a FULL stock ROM?
Do you know what caused the soft brick?

The same thing; I also tried with the Windows Odin software; the phone reports that message and the software's log gives no details other than "FAILED"

No, the phone came second hand but its previous owner didn't strike me as someone who would be experimenting with custom ROMs or anything like that; for them the phone stopped working and a new one was needed. It doesn't have its knox bit triggered.
Thanks

[Q] How to unbrick the note2 (n7100) ?

Guys my english is not that good so if you dont understand something tell me.
my friend gave me his phone becouse i had to fix it for him. i thought it was an usual brick, but when i try to flash the rom with odin it fails on the nand writing. when i get in to recovery mode i see that the device doesnt mount the system file (cache, efs etc...). I tried a nand erase + repartition but odin fails them too. i dont think that the nand is broken, just something doesnt allow me to access
what should i do?
Try this
Have u tried mounting external usb stick with otg cable? what version of odin re u using?
Alternatively try installing custom recovery like philz and then try flashing a rom.
let me know if that helps.
Hey, i have the same problem.
i took my phone out of my pocket and it was turned off. I tried to boot it but it got stuck at Galaxy Note II logo.
When i opened recovery (i use teamwin) , it shows in the log similar error messages to yours. It won't mount any of the partitions. I also tried repartition with odin, but it fails too.
I think the internal storage (the emmc) is broken in our phones and we can't really do anything about it. But i'm not sure.

Internal flash corrupted?

Today my N7100 suddenly rebooted without any warning and got stuck at initial Samsung boot logo (even sound gets into loop). I managed to enter recovery and tried to wipe cache partition. But every time I try to wipe anything or delete via twrp file manager - phone reboots
Should I try re-partitioning via Odin? What pit file do I use?

you can try to use Odin, but probably you have faulty eMMC, many similiar cases around the forums about rebooting and stuck on Samsung logo.
Probably PC won't recognise your phone and there will be nothing else to do, but to give it to service
Miracles happens! Re-partitioned and fully erased nand via Odin and managed to upload the rom! Have tried 3 time before it succeed (crashed few time on system and cache image writing). Everything seems fine so far. Won't upgrade the rom from the stock 4.1.2 for a while to keep phone working. I have the insane emmc chip by the way. Hope it won't fail again.

Rogers - Device memory damaged

I have searched through the forum but haven't found any answer. I got this message on my phone 2 days ago,
"Device memory damaged, reset your device". I have tried to reset using the button provided but nothing happens. Have tried to Odin the factory ROM but it fails with "Write operation failed". Have also tried to flash CWM recovery and Philz recovery and they both flash fine but I have the same message when I boot.
Have tried to boot to CWM menu and tried to format/wipe/reset but to no avial. I get error saying can't mount /cache, an't read /cache.
Have not been able to find a Rogers pit file to repartition using Odin. All the files supplied are for SGH-I747 or i9300, I need one for SGH-I747M. Any body has one?
Any way to bring the phone back?
Does Odin flash any part of the stock rom? Which part fails to be written?

HELP! restoring stock rom on Verizon galaxy S5 (G900V)

First of all to admins..., I hope I'm posting this in the right section. If I'm not, please move it or direct me.
I have a Verizon S5 - G900V that is soft bricked and I have been pulling my hair out trying to restore stock rom to it via Odin. It fails every time. I have tried so many versions - some fail with aboot, which I understand means that th version I'm flashing is older and I can't downgrade. Fair enough. The only one that seems to work is G900VVRU2DPD1 (which shows up as the version in recovery mode) but it fails at loading the SYSTEM stage. In Odin on Windows it shows fail (AUTH) an on t device it shows secure check fail: system
Reactivation lock on the device in download mode shows OFF And I can't boot into the OS to verify that.
I have all the necessary device drivers installed in windows.
The device, I believe, is not rooted.
Using kies doesn't work because I asks for for device serial which I d know and does n show under the battery (only shows IMEI an model) and using the Verizon repair Assistant doesn't even see the device
I have wiped cache partition and did factory reset from recovery mode.
I have done exhaustive Google searches an been on many xda dev posts for weeks and not finding anything that works.
I've also tried pushing with adb sideload....didnt work.
The only thing I can think of, and think I might have read somewhere, is that my problems are caused by a locked bootloader. I anyone here able to attest to that?
One other thing...in recovery mode, if I select mount system, it gives errors in red e:Failed to mount /system (invalid argument).
Any experts here able to help me get passed this to successfully flash stock rom (or any rom even modified) back into this device and end my madness?
Any help would be appreciated.
Thanks in advance
Bump
any experts out there able to help me on this one?

Can't access recovery and bootloader

Hi,
I have Samsung Galaxy S4 Mini (serrano3gxx). I was using this ROM and CWM recovery. I really don't know how it happened. My phone shut down and when I booted it, I saw this message "Encryption Unsuccessful", so I was not able to access my storage. Then, I've searched how to fix this. I tried to backup storage in recovery and I got this error every time "Can't mount /system, /cache, /data", even while trying to mount them manually. After a few try (flashing etc.), I've become to not access ROM (also bootloader) and CWM recovery. When I tried to access them, I only got "Black screen" and nothing appeared on screen. Then, I could access "Download Mode". At this point, I've tried to flash another ROMs (including stock ROM) and recoveries via Odin. Firstly, Odin detected my phone but ADB not. Secondly, when I tried to flash something that I mentioned, Odin's log screen stuck on "Initialization" step. I've waited 1 hour only for flashing recovery... Nothing flashed and still stuck same step...
Now, actual situation is that I can't access even Download Mode! Before this, phone was shaking when I plugged it to charger or USB port and tried to power it on. Now, this is also changed, it is not shaking...
Guys, I am saying "wth is it" now. These occurred step by step:
1. Shut down and message "Encryption failed/unsuccessful".
2. Can't mount /system /cache /data.
3. Can't access both of ROM (bootloader) and recovery // Black screen
4. Can't access Download Mode.
Note that, all of required drivers installed, even Kies. By the way, Kies detected my phone but it could not complete loading to recognize.
I've found this article but I don't know if it is solution.
I guess phone's storage is corrupted.
So, my phone's storage is fried? What should I do? Thanks for helps I will get.
Try flashing the complete stock rom not just the recovery. Or find a fix and flash it!!
Maybe you should get a pit file and flash that. Reanimated a S3 mini with that.

As I wrote, I can't access/reach recovery and download mode. How can I do that if you know it? I am still searching how to fix this but it is hopeless case I guess. "getting a pit file" is ok. I found it for a few roms including stock rom. But how can I flash it? I could not find this.
