cannot mount internal storage after downgrade to 4.3

I tried to downgrade to 148 to get the cm install to work. Lost access to internal storage. I was using twrp 2.8.7.0 or 2.8.0, flashed the rooted stock ROM from another post here and lost access. I've tried the su command "restorecon -v -R /data/media" and now I can see the internal storage from the settings menu but not change the location from there.

Here is my terminal command "mount" result

[GT-i9000] Unable to mount /system and /data and a few questions

I am working on Ubuntu 15.04 and I used the Heimdall suite to do the necessary flashing.

Before I start: I created this post to share my experience with trying to flash a custom ROM on the GT-i9000 and receive some suggestions, though my main concern is the fact that I am unable to mount /system and /data. And yes, I have read posts concerning this issues, but they were too vague, so I decided to write my own.

First I figured I should flash a custom recovery, so I tried flashing the latest CWM for the galaxysmtd in Download Mode and it appeared to have been successful, though when I pressed the 3-button-combo (UP-HOME-POWER), It would boot the default Android System Recovery.

I tried flashing a few CWM and TWRP recoveries (though I didn't try PhilZ Touch, because goo.im is down and I couldn't find a proper PhilZ Touch recovery anywhere else), though I noticed that none of them would work, even though the flash was successful. So I figured I could try flashing a kernel, which would include some recovery - and it worked, to my surprise, though after attempting to wipe a few folders, I got the error: unable to mount /system and /data.

So I came to realise that the only way for me to get a working custom recovery was to flash a kernel, which should include a working recovery. So I ended up flashing Mackay_kernel_0.692_twrp_CMC-signed.zip, which includes TWRP v2.8.0.0. The recovery seems to work fine, though the same error persists: unable to mount /system and /data.

I tried formatting /system and /data, though to no avail: it just forced the recovery to reboot (I have attached the recovery log to this post).

Any help is much appreciated!

[Q] E: Unable to mount '/system': Bricked after ROM Update

I tried to update my device with the newest ROM (Dirty Unicorns) and somehow bricked it. ...
The device just stuck in the flashing process for over 10 hours. After TWRP and Fastboot were still working, I tried a lot of things to revive the system, but everything I tried went wrong.
First I tried to flash the factory image. The strange thing: that seamed to work well (with Wugfresh toolkit), but the device still stuck in a bootloop.
Everything I try in the recovery mode ends by TWRP with "E: Unable to mount '/system'" (in red letters). So I tried to flash the factory image again and wiped the device in the newly flashed Revovery completely.
No change: "Updating partition details... E: Unable to mount '/system'".
- ABD sideload doesn't work. I tried to flash system.img. No success.
- Bootloader is unlocked. V3.44.1.0123
- Newest TWRP (twrp-2.8.7.0-flounder.img)

Here are the best Android-experts worldwide! So can someone please help me?
Thanks in advance!!

Failed to mount /data and frozen after factory reset, HELP!

I have what's probably a unique situation, though I hope not. For background info, I bought two I747s, one white and one blue, each with issues, but I intended to put parts together to end up with one good one.

When I did a factory reset on the blue one via the recovery menu, it returned a bunch of errors along the lines of "failed to mount /data." Then when it rebooted it would hang on the Samsung logo. Back in recovery mode it returns more of the same errors just booting into recovery mode, and factory reset still returns more of the same errors and doesn't fix anything. I flashed 4.3 with Odin in an attempt to fix it, but I got the boards mixed up, and that one had 4.4 on it, not 4.1 like I thought. I'm pretty sure it's hard bricked now (that whole can't downgrade thing) because it's unresponsive to everything. Though my computer does recognize that it's plugged in, more on that later.

So I figured, fine, I screwed up, I'll just use the other board with 4.1 on it from the white phone. Except when I did a factory reset on that one, it did the exact same thing! Same errors, same problem stuck at the Samsung logo. Except this time I'm not flashing sh*t until I know exactly what I need to do to fix it. In another post where the guy had the same issue with 4.1.1, it was solved by flashing 4.3 with Odin. And another post where the guy had no idea what version he had, he just knew it was lower than 4.3, his problem was also solved by flashing 4.3, But since my last efforts failed miserably, I'm very reluctant to try it until I get some knowledgeable input. I don't remember exactly which version is on there, it's 4.1.something. I'd also prefer not to upgrade beyond 4.1 because I'd like to unlock it and from what I'm reading you can only do it for free if you're on 4.1. So I guess I need a link to an Odin flashable 4.1 package?

As for the poor blue phone that used to have 4.4.something, and was mistakenly flashed with 4.3, I've heard about JTAG but I don't quite understand it, and I'm not sure it would work in my case since a lot of what I'm reading says that bricking which occurs from downgrading is often unfixable. However, Windows recognizes that a device is plugged in when I attach it via USB. It shows up in the Device Manager as QHSUSB_DLOAD. I am currently researching more on this and the method of booting from an SD card, except I don't have an SD card reader at the moment.

Any assistance, advice, links, information, and plain ole encouragement are always welcome and appreciated.

twrp won't mount internal sdcard

My phone was just sitting on the charger and it reboooted while I was away from it. IT was sitting on the larger Samsung Galaxy S3 logo screen. I could not get the phone to boot. I went into TWRP and it took a much longer time to get into recovery mode. When I do, it says there is no OS! When I look in the log, this is what I see:

E: Could not mount /data and unable to find crypto footer
E: Unable to mount '/data'
E: Unable to recreate /data/media folder.
Updating partition details
E: Unable to mount '/system'
E: Unable to mount '/data'
E: Unable to mount '/cache'
E: Unable to mount internal storage
...

Can not mount /cache or /data partitions

Hello all,

I recently wiped my phone clean, to give it to a friend, through TWRP. I was stupidly drunk in the process and didn't realize that I wiped every possible partition! At this point, I have no OS, no data, but can still access recovery and the bootloader without an issue (thank god! not a brick!). I am fairly good with working on this phone, but I have ran in to a couple problems. Apparently, RUU's are NOT working for returning to stock. I have tried many combinations of firmware versions, including the original out of the box RUU's for my ATT HTC One. Not a single one has worked. However, interestingly enough the RUU will run without an error, but gets stuck in stage 1/6. I've left it overnight and still stays in stage 1.

After doing intensive research on the issue, I realized that my problems possibly pertain to the fact that I am unable to mount /cache and /data. I can't even repair permissions because of this, so it has truly hindered all possible fixes. I believe it may be due to the fact that I might not have root anymore, but I don't know how to get root without a system partition. TWRP attempts to do an auto root but fails each time.

Wonderfully enough, I have issues using ADB Sideload. It will flash a .zip until 92%, at which point it stops with an unknown error. I've tried with multiple .zip's found from HTC1GURU's Stock ROM Guru Reset downloads page. No avail. I've looked into other fixes and still no luck.

SO...I'm practically at my wit's end, about to pray to Mobile Phone Buddha that this thing will work again...

Any suggestions?

"Please Help" I can't get my sd card to mount in my phone...

I have an HTC Desire 626s. My previous phone was HTC Desire 601. I purchased a memory card. The card is: Professional ULTRA PLUS SanDisk 64GB MicroSDHC.
I loaded the card into the new phone and it said "unavailable" to add insult to injury it immediately said: "sd card safe to remove" like I unmounted the card. The problem is I never even got the chance to mount it in the first place. Then tried copying the info off the card and just reformatting the sd card. I saved the info on my laptop and put it back in the phone to begin the formatting process. I started the formatting process and after 4 hrs. of it doing nothing but looking as if it was trying to work. I finally put it in the old phone just to format it. It took my old phone a few minutes and it was done. Then I put it back into the new and still the same issues are occurring. I really need some help here. I spent a lot of money on my sd card and the phone.

"unable to mount /system" in TWRP

Hello, I was trying to install ROM Arcatarc's EMUmIZERO SUPERLEGGERA. I installed TWRP v2.8.2.0, I did backup of all my data and system, wiped it and tried to install that ROM, but always got message "unable to mount /system". So I tried to restore my backup, but always ended with same message "unable to mount /system". I got this message when I do pretty much everything. Now I have no system and cannot use my phone. Please help.

Following today's system upgrade my SD card won't mount

I've had my Idol 3 for a couple of weeks now and I just love it . . . so do my 'green' friends! However . . .

My Idol 3 got a major upgrade today, and now the phone won't permit mounting of the SD card . . . home of many apps!

The option under Settings/Storage is not greyed out, it's just that when I tap 'Mount SD card' nothing happens. I'm also getting a continuous notice, i.e. "SD card safe to remove".

The card was not removed either before or after the upgrade, but since I have had the above problem I have done reboots, restarts and hard reboots, and and have removed and replaced the card a couple of times . . . . I'm at a loss on this one!

Does anyone have any suggestions that will help me get the SD card mounted please?

Many thanks!

S4 i9500 efs mount problem

My Phone is S4 i9500. I installed the program called SWAPPER. After changing some preferances i run the program and phone shut down. When i start the phone again it stuck on GALAXY S4 Logo. I enter the Recovery mod i realized that error ''not mount efs''.
I know the problem. I remember that SWAPPER use ''mmcblkop3'' as default and i forget to change before it run and SWAPPER formatted the place ''mmcblkop3'' as swappfile format. It means that the places containing efs information formatted.
I install the stoch firmware and using ADB shell and made system working but IMEI is like 0049........ Everything works normally including wifi but phone does not.
1-First of all i need to mount EFS folder. I read many forums but anyhow i coud not mount efs folder. Does someone knows how to efs is mounted? To mount efs can we use ODIN ? and how?
2- Then after i need information to save my original IMEI and the t info to use phone normally.

I will be pleased if someone help me.
Best Regards,

Nexus 7 magnetic car mount options

I currently have a pro clip car mount that I was using daily with my Nexus 6. I was doing some reading today and figured that I should wipe off my dusty Nexus 7 and put it to good use. I was thinking about using the stock proclip mounting base that I have and attaching a magnetic car mount for my Nexus 7. To give you an idea of what I'm talking here is a video: https://www.youtube.com/watch?v=UFg0dzAVORY

Does anyone have any experience using magnetic mounts with their Nexus 7? What advice or products would you recommend? Did anyone have issues with the size and weight of the Nexus 7 causing issues with keeping it stable?

Wireless Charging With Metal Plate For Magnetic Mount

Hi.

Just got a new S6 and I thought I would try out the new wireless charging which I think is great. I installed my metal plate however into my phone case to use my magnetic phone mount in my car but the wireless charging no longer works with this small 1” by 1” plate in the back. I’ve tried moving the plate around and can get the charging to work but if any of the plate is in contact with the coil it gets really hot fairly quickly.

I am able to move the metal plate far enough down in my case that it doesn’t interfere at all with the charging or get hot but then my phone isn’t as secure on the mount.

Does anyone have any recommendations or suggestions to get these two things to work in harmony?

I’m not interested in buying a new mount that does both. I’d like to keep what I already have.

In the end if I had to pick one or of the other, the magnetic mount would be my pick.

Just wanted to see if anyone else has the same problem.

E: unable to mount '/system'

Hi!
I have Mate 7 L09 (2gb of ram). Before i had lollipop 5.1.1 (b312) on my phone. Everything was ok, but i remembered that before on kitkat i had some "ios" animation pack installed and it was ok.
So from custom recovery, i installed that pack. (big mistake, don't do it) my phone started by i doesn't work properly. I had access only to settings. After that i did a wipe and a factory reset.
And from here my phone didn't want to boot. I only see the huawei logo. I tried to install the transition pack (by pressing vol - + vol + power) after many attempts i installed the pack. When i wanted to install the kitkat it froze at 90%. I did another wipe, another factory reset. And from here i tried a lot of combination. Lollipop bootloader, with kikkat installer, lollipop bootloader with update pack for lollipop, with transition pack. I tried also with kikkat bootloader and all the combination from above. When i install a custom twrp it tells me that i don't have any operation system on my phone.
I saw that i can't access system partition. When i want to wipe system partition it gives this error: E: unable to mount '/system'
What should i do?
Can you help me?

Thank you!
