[Q] Clorkworkmod cant find sd. Is it bricked?

Hi. I was loading a rom in recovery and first wiped system and data. when I went install the new rom I got the error "E:Can't mount /dev/block/mmcblk0p1 (no such device)". In other words, I have wiped the old and it cant find the new rom.
Previously I rooted by UnRevoked so I have not previously set up android sdk.
Am I screwed
Thanks

Have you tried a different SD card or the CD card in another PC?
Could be a faulty sd, or if not maybe try cleaning the contacts on the card and phone?

the card seems ok. It can be read via USB from recovery.

Is there any way I can set up a terminal connection and flash a rom from my computer?

I'm having the exact same issue with r6. The SD just won't mount even in recovery. When this happens there is literally nothing else to do, we need a solution!!!

Sorry to hear it Doogle. Im out of ideas too

Pretty lucky to not be the only one tho
Just so you know, mine is definitely USB bricked, but the SD thing is stopping me from being able to fix this.
It's quite unusual.

Any idea if its possible to set up a terminal?

or does usb bricked mean your comp cant see the phone?

I set up a thread earlier to find that out. No replies
Yeah when the phone is USB bricked the PC just can't detect it,
so it's impossible to flash RUUs, so I'm up against the wall unless
I can get this working

When Clockworkmod didn't find my SD, but card reader showed it ok, I used SDFormater to reformat card (remowed all partitions) and when formated in recovery.

Have you tried reformatting your SD mate? The chance of that fixing it isn't high but it's worth a shot...I'm reformatting at the mo

Basically, the SD card is not mounting (if it's the same as me), so regardless of what .zips might be on it, it can't flash them...

You're not using quick format option are you?
Because a proper full format is much more effective,
and takes a while to complete.

i am now waiting for sdformatter to do its magic. I hope it it learnt to format at Hogwarts!

nope. It still cant mount it

[Q] Dropped my phone - Now stuck in bootscreen

Hello guys,
I woke up too early this morning, and i accidentally knocked my phone off the stairs. It fell about 2 meters, bounced and then fell another meter, bounced and fell another meter and stopped.
Thankfully it was in a silicon case (i think that's what made it bounce) and there are no visible damages.
I picked it up, and it seemed to be working. After a few secs it went into sleep mode and would not wake up.
I removed the battery and rebooted, and i got the HTC screen, then the nexus boot screen and it stays stuck on the nexus boot.
I then entered recovery mode and thought i would try and restore my backup. I get the following message:
E: Can't mount /dev/block/mmcblk0p1 (or /dev/block/mmcblk0)
(No such file or directory)
E: Can't mount /sdcard
I took off the SD card, put it my pc and it works just fine.
I got another SD card, copied a rom onto it and tried to reinstall through recovery.
I did a wipe/data factory reset and tried to install the rom.
I got the same message...
Is my Desire toast? It's only six months old...
I was running Defrost6.1 and using psfMod 0.9.7.2 as my recovery.
Any advice would be extremely appreciated.
Thanks
aalex
UPDATE
I did another wipe data / factory reset, and i rebooted.
The rom starts up, without any of my previous settings of course, but I still cannot mount my SD card.
From file manager, it seems that it is being mounted, but no files are listed...
When i try with gallery it reports "SD card unmounted or not present".
Any insights?

Drop it again, it helps

I tried to mount as usb storage, it seems that it mounts, my pc picks up an additional drive but when i double click on this drive it just says that it cannot be read...

With your SD card in your phone go into settings then storage and unmount SD card. Then format your SD card from your phones menu and it should mount the SD card see if that worked.

Hi ste1164,
Thanks for responding. My problem is that my phone cannot pickup the existence of an SD card.

This is a typical USB-brick. I've had one a few weeks ago. You should look at this thread: http://forum.xda-developers.com/showthread.php?t=691639&highlight=usb+brick.
If you're new to this, it can be hard to get it working again. Just let me know if you have any problems. It took me a few hours to get it done

From fastboot via ADB, execute "fastboot oem enableqxdm 0" and then reboot it with "fastboot reboot" command.
See if it works.
If you don't remember how to do the above, just search.

its not a usb brick, thats a software brick.... it sounds to me like you have a corrupt sd card, sd cards are very delecate and this can happen from a sudden impact, try formatting the card in windows explorer, obviously you cannot format your sd-ext using windows so try gparted or ubuntu to format your other partition.

Can't be sdcard, op said tried sdcard in PC and tried different sdcard...same result, must be sdcard reader or something.
You never know, might be a USB brick, just happened before the drop and was brought on by the reset...but I agree probably is hardware fault.
Is it possible to flash stock rom from fastboot without sdcard? Could try warranty repair then...

sorry i didnt notice that, could be a usb brick but like i said thats S/W related and i doubt dropping your phone could cause such an error, +1 suppose the sudden reset could cause the usb brick especially if the device was reading or writing to the sd card when it happened, could also be the sd card reader in the device has been damaged or one of the internal components. can the device read the sim card? if it dosent, could be a usb brick

Just a thought...is the sdcard reader attached by a ribbon? (never seen the inside of my desire, hope I never have to)
I'm sure I've heard of a few desires that can't read sdcard anymore, I reckon it's either attached by ribbon or it's the most delicate part of the phone.
I'm hoping it's a loose ribbon because that's an easy fix, even I could do that.

Hey guys,
Thanks to all of you for responding.
My sim card works just fine. I can make and receive calls, texts, go online via 3g and Wifi, connect through bluetooth. As far as i can tell, my phone does everythind it did before except mount an SD card. Also, the android market keeps crashing, and if i try and download anything from the net i get a prompt saying that i need an sd card to download.
So far I took the SD card and put it in my pc. I formated it, tried again but it didnt work.
I then tried a brand new sd card and that didn't work either.
However, I did not format the old card's ext2 partition, and the new sd doesn't have an ext partition yet.
Would this point to a USB Brick as mentioned above?
Would it be possible for me to flash the stock rom on the device?
Thanks once again, to all of you.

Yes, that should solve your problem. I had the same problem a few weeks ago, but that included a malfunctioning usb, even charging didn't work correctly.
To fix the sd-card, you should run the above command using the tool fastboot, available in the Android sdk. After downloading, cd to the tools folder in the sdk and then run the command while your phone is connected to your pc in fastboot mode. Then it should work again.

Hey koenvbeek,
Thanks for the help. I think i may need a bit more of it
Here is what i did so far:
I used Nephrons guide to download and install ADB.
I then rebooted to bootloader. The phone displays "fastboot" and then when i plug it in it dispalys fastboot-usb
I then went to the ADB tools directory and tried to run the command.
I got a message saying the command cannot be run because adbwinapi.dll is missing from my system, and asking me to reinstall everything...
Clearly i made a mistake somewhere but where?

I don't think you made a mistake
Either the requested file is missing, or it can't be used by your computer. First check if the file is present. If not, google for it.
If it is present, your computer can't use it for some reason. Are you on a 64-bit OS? If you're on Vista/7: did you open the cmd promt as admin?

Yeah, nothing wrong, it's just that the API library is missing.
Download it from the attachment here, and put it in the "tools" folder, then try again.
Edit: As you can see it's in an archive, since dll attachment is not enabled here, so extract the file from it.

[SOLVED] MicroSD to Internal Storage swap not working

Hi,
I was running Flex ROM w/ the MicroSD swap Mod. I shutdown the device and took out the memory card. I used the card for transferring some files. After I inserted back the card and turned on my device, the A100 was no longer detecting the MicroSD swap Mod. I tried to install a new ROM, Green ICS, but it is still not working. The Internal and SD storage are reflecting the Internal Storage. I have set the permission correctly on the install-recovery.sh but I cannot get the MicroSD swap to work. Could anyone please help me with this?
Thank you.

Are you sure you set the right permissions? If you used Root Explorer, all the boxes must be checked. Also, have you tried running the script on boot (using script manager)? You could even execute the script manually.

Since this started after using the card outside of the tab to transfer files, I would suggest checking it for errors, or even formatting it and trying again. A bad removal from a PC can cause this to come up, it seems to happen occasionally on all devices when the card is removed and used on either another device or on a PC. Android won't always notice something is wrong, just won't mount it without reporting errors or things like that mount swap script will fail as the mounting isn't completed on the external SD, so it can't swap mount points (one is missing).
I say bad removal from PC because, windows in particular, will allow you to unmount for removal while STILL writing to it, which makes no sense to me. In my experience, even in linux, the file transfer dialog will say its complete, however the card is still being written to for up to a few minutes afterwards. The card reader I use has an activity LED on it, and I don't even attempt to unmount (or remove in windows) the device until after that has stopped blinking for a few seconds. Removal while still writing can cause filesystem errors that android will usually pick up, but not always.
If possible, try the card in another android device and see if it mounts.
If not, copy all of your data off to your PC, then format it FAT32, then insert into the tab and see if it picks it up.
If not, insert it into the tab and see if it will allow formatting from there.
If not, insert it into another android device and see if it will allow formatting from there.
If not, perhaps wiping in CWM or TWRP will allow it to be mounted.
If recovery will not mount it, even after ALL of the above steps, then the card may just be bad, its flash memory, it happens. A recovery log would help if this happens, and point out why it's failing. ADB shell can then be used to attempt to repair it by e2fsck for error checking, and mke2fs to format it. Final last ditch is zero it out and format again. That should overwrite any bad areas with zeros and "hide" the bad data by writing zeros over it. Takes a LONG time to do this though, roughly 20 minutes per 6 GB. But before we ever get to needing to zero it out, the other tools will report something like a bad super block which can easily cause failed mounts and won't always be reported in android.

Thank you for the replies. I have already reformatted the microsd card. It is actually read by the tablet and no problem using it but I still cannot swap the memory. It was working before. The permissions are correct. I've set it with everything checked for rwx. After rebooting, my internal memory is still the same but the SD storage becomes a duplicate of the internal storage. I have tried using script manager. I'm not sure though if I ran the script properly. Is there any guide on running the install-recovery.sh on script manager? Thank you again in advance.

To run it manually in Script Manager, just select it and click run (make sure you are browsing as root). You could also use Root Explorer (a bit more simple) - Simply tap it and choose execute.

Thank you for the response again. I tried executing it on Root Explorer but nothing happened. It says install-recovery.sh was executed but after restarting, nothing happened. My bootloader is unlocked and I'm using TWRP 2.1.1+. Both Flex Reaper and Green ICS ROMs no longer works with the MSD2INT Mod on my tablet. I'll try reverting back to HC then re-do the whole process of unlocking bootloader and rooting. If anyone has an idea or similar issue, please assist. Thank you.

If you use Root Explorer to do it, it will not work after a reboot. You would just execute it and use it from there (and re-execute after each reboot). Script Manager is best since you can set it to automatically execute the script on boot.

Thank you. I tried using Script Manager on /system/etc/install-recovery.sh and set SU and Boot then saved it. I rebooted but still not working. I'll just try from scratch and see if I get it working again.

I added an edit to this post
longest edit ever
Which explains the steps for both methods of using this script, acer stock/modified or AOSP based which uses script manager. Give that a read, it's quite detailed and boring, but it works.
This is also going to be added into the A100 guide as I get around to it, for anyone else having issues. Mainly, make sure the permissions are correct if it's not working, and you're giving it a minute to show up.

Thank you to everyone who replied. I was able to determine the issue and fixed it. It was a problem with my microSD card. pio was right. The card was corrupted. It was being mounted and detected in the ROM but I was not able to mount it on the recovery. It seems it is not read during boot up and it only gets mounted when the ROM is loaded. I tried reformatting it using the Windows format tool but it still didn't fix it. I was able to use the SD Formatter v3.1 application to fix the problem. The microSD to internal storage mod is now working. I'm back using the Green ICS ROM. Thanks again for the help and suggestions.

[Q] External SD Card Read-Only Problem

I tried researching this but wasn't successful finding same exact problem or solution. I'm on 4.4.2 Baseband N900TUVUCNB4 rooted with stock rom and ext sd fix. Everything was working fine until recently. My external SD card has inexplicably become read-only, both on the phone and on my desktop. I first noticed this last week when the phone camera began having problems writing to external SD card, and now I can't sync music to card. I've tried formatting on the phone and desktop, both quick and full but no dice. On the phone, I am able to delete individual files or folders but they reappear. On the PC, I can view but get write protect message when trying to format. Anyone else come across this or have suggestions?

Happened with me once with a different phone/OS. Weird thing is that it was only for a particular SD card. I put a different card and it worked.
It turned out to be a problem with the card (dunno how thats possible though).

What's the brand of your SD card?

I have the exact same problem with my SGNote 2 and SanDisk 64gb micro SD card. First I lost some pics I have taken that day. I searched through with a file rescue tool but they were nowhere to be found. Deleted files reappear, and the ones I copied from internal SD dissappear.

It's a SanDisk 64gb class 10.

Glad to hear I'm not the only one. Maybe we can share the solution when we find one. I'm using internal memory in the meantime for new media files, but frustrated that I am not able to use the rest of the memory available on my card.

SanDisk works fine for me, maybe your sd card is a faulty one, let's wait for a while here and maybe someone could answer your question and hopefully solve your problem

Thanks, Lorettaa. It seems like that's the only option right now, since I can't find any other info about it on XDA.

I have full read access to every file, just can't do anything else

I have the exact same problem, i tried many options , used some softwares in windows to format , wipe, fix, modify. nothing works.
One possible reason for this problem is file system errors , which can be rectified using the 'error checking' option in windows and 'fixing the file system errors'
But that doesnt solve my problem, even after formatting using advanced softwares, the sd card is the same - no files deleted, no files added...
The fat as well as ext4 parition is not formattable now in anyway.so the possible conclusion is 'sd card is going to fail'.. Take a backup before you loose the read capability.

Recuva is a good, free tool (from the people that make CCleaner) to deleted recover photos.

And one possible reason for a false error condition is a corrupt system. This is normally an unlikely possibility but it is very likely on devices that have had partition images written to (i.e. a flashed ROM). If you have done all you can to the SD card and if the errors are not only on one SD card then wipe everything and load a backup. If you still get errors then wipe everything and revert to stock to see if they still occur.

Micro SD Card says corrupted after installing Android Marshmallow in my LG G3 D858HK

Hi people. I had installed this ROM (Marshmallow 6.0) in my LG G3 D858HK dual sim. The link to the ROM is http://forum.xda-developers.com/lg-g3/development/lg-g3-d856-7-8-android-marshmallow-t3294053
But after installing the same my MicroSD card says its corrupted and asks to format it. I have formatted it several times and also by PC with a card reader. But still the issue persists. I don't get the option to set up my card as either INTERNAL or PORTABLE storage as it should be in Marshmallow ROMS. It directly starts to format as Portable storage and starts at 20% and shows successfully formatted. But still it shows that the card is corrupted. My card is working fine. I checked it. Please help.

I have the same problem and not yet identified the reason for this. Have you tried other ROMs? For me it is also happening on CM 13 and CandySix.

Answer.
Hope that helps, it worked for me with the same problem and works always....

I have the same issue with a Samsung 64GB microSD in a LG G3 d851 (T-Mobile USA). The card works fine in Windows and Android Lollipop. However I am testing several Marshmallow ROMs and so far I got this corrupted message in LightDark, Turbo and DU ROMs. However it works fine in Tesla-M. All of them are AOSP Android M ROMs. It seems that there is a problem somewhere but at least Tesla-M tells us that it can be fixed.

Fat32 lads, instead of exFAT format to fat32. The root in MM causes exFAT cards not to be read and stupidly the phone formats it to exFAT. Also the SIM contacts won't appear, instead you have to download an app to copy them from sim to phone.

I'm experiencing something similar.
I am on fulmics 4.2 on a d855. I had no problems for some weeks, than the phone started mounting and unmounting my sdcard, I tried all the suggestions I read online. Like slow formatting (tried all the types of partition), also I tried with the phone format. My best result was the read of the sdcard for just some hours, but then it started auto-expelling it.
I obviously tried with more sdcards and it's not a problem with them. Any suggestions? It's a software problem or an internal hardware problem?

I tried change the kernel a xceed and the sd card is recognized but not funcionally complete,(the radio fm do not work with xceed)

Hi all,
I found out that the same SD card I have since I bought the S5, May 2014, just got corrupted.
It won’t format in the phone, I use the AParted, ES File Explorer, FX Explorer and it never work.
I can still use it in a camera, PC, another Phone and it worked fine!
I put the card back in my PC, reformat in Fat32, ext4, NTFS and each time never worked in the S5.
I did the same thing with a bran new one too, same results.
It starts after updating SuperSU 2.61 to 2.71, in Marshmallow.
Few days’ work fine and then, corrupted.
I tried many options people have here and still the same result, corrupted.
I fix it (I hope) with doing a full factory reset in Marshmallow first.
Got to TWRP and did a full Wipe, Format Data and Adv. Wipe; select everything.
Yes, that clean a lot.
Use Odin and re-flash Marshmallow.
Everything is fine now, but it is only a few days that I did this, so it might still happen.
Could it be the version of SUperSU I took that has something? Or It is actually Marshmallow 6.0.1 with SuperSU ?
We might never know as the version change often.
Hope that will help someone.

Hi all,
I found out that the same SD card I have since I bought the S5, May 2014, just got corrupted.
It won’t format in the phone, I use the AParted, ES File Explorer, FX Explorer and it never work.
I can still use it in a camera, PC, another Phone and it worked fine!
I put the card back in my PC, reformat in Fat32, ext4, NTFS and each time never worked in the S5.
I did the same thing with a bran new one too, same results.
It starts after updating SuperSU 2.61 to 2.71, in Marshmallow.
Few days’ work fine and then, corrupted.

Hi all,
Here it is again, my SD card is corrupted again by the OS… but I can access the card by my PC or another phone!
So it seams to be a combination of OS 6.0.1 (Canadian Rogers), how it is rooted (Twrp) and the SuperSU free v2.76.
I’ll wipe the phone again and re-install the original Os from the carrier, no Root & no SuperSU.
I’ll wait for a week and see.
Keep you posted.
Have a great one!

Hi All,
I rooted by phone this week also using the KingRoot method and also had the same issue. The below steps resolved it for myself and hopefully for you.
Since this is my first post I can't paste the URL to the site as the forum won't let me, so you'll have to google it, sorry about that.
Google - 32fat guiformat and look for the site 'GUI Format - Ridgecrop Consultants Ltd'
Download the program by clicking on the picture.
Run the program and select the drive letter of your memory card. Set the Allocation unit size to 32768 and untick Quick Format the press Start.
The format process takes maybe 45mins. But afterwards you'll have a full 64GB card formatted as FAT32 and will work in your phone again. Hope this helps you...
Enjoy your day.

If you can verify that more than one card works in a computer but not on the phone, and that formatting the card in the phone goes to 20 % very quickly, while afterwards going to 100 % but still tells you it´s corrupted, then indeed it´s simply the installation of Marshmellow that suddenly no longer wants to work with the file system of the card.
For me, the 32fat guiformat program told me that card was locked by another application, so I did it manually:
In windows elevated command prompt - after backing up eventual data on the card:
diskpart
list disk
(now find out which one is your sdcard, let´s call it x)
select disk x
clean
create partition primary
select partition 1
format fs=fat32
When the format is finished, if the cards size is beyond 32 GB, you´ll get a message about that the disk is too big.
At this point I managed though to make a quick format in the before mentioned FAT32 GUI Format program, and bingo - the card is recognized in the phone again.
No need for the diskpart stuff of course, if you already had success with the GUI thingy, just telling in case anyone experiences the same problems as me.
It may be that there´s a way to tell diskpart to use a different cluster size to avoid the error at the end, and also there may be a trick to make the card available to fat32gui. without first going through the diskpart step In my case though, I had the error on two different computers, on which none of them were accessing the card from any applications, disk management, win explorer etc.
Finally I´d like to add that this is not a general error for all Marshmallow phones: My huawei p8 worked fine with the card, also on Marshmallow, before I had to reformat it to fat32.
It´s a pretty sucky bug: Never mind the hassle of formatting the card, as long it works. What bothers me is the 4 GB limit of files in fat32. It´s easy to have a movie nowadays which is larger than that.
PS: Some people recommend using an app called aparted to format the card on the phone, which now has another name. I tried that, but it kept on closing itself, so perhaps it´s not compatible with Marshmallow or the same plus LG G3.

Hi people. I had installed this ROM (Marshmallow 6.0) in my LG G3 D858HK dual sim. The link to the ROM is http://forum.xda-developers.com/lg-g3/development/lg-g3-d856-7-8-android-marshmallow-t3294053
But after installing the same my MicroSD card says its corrupted and asks to format it. I have formatted it several times and also by PC with a card reader. But still the issue persists. I don't get the option to set up my card as either INTERNAL or PORTABLE storage as it should be in Marshmallow ROMS. It directly starts to format as Portable storage and starts at 20% and shows successfully formatted. But still it shows that the card is corrupted. My card is working fine. I checked it. Please help.

same problem i tried everything aparted, wiping partition from twrp, cmd promt.

maybe busybox
I know this is an old thread but I've recently had this same situation but I found it was a result of installing busybox with Busybox Pro from Stericson. I used the "Smart Install" feature and selected to "Replace all symlinks" and "Clean Mode".
Basically, I believe by doing clean mode and replacing all symlinks, I had replaced needed System applets which somehow had hindered the OS from being able to correctly mount any External SD Card.
After using TWRP to factory reset (Wipe System, Data, Dalvik, Cache, Internal Storage) I Odin Flashed the latest stock firmware and then proceeded to root, etc. BTW, My phone is a T-Mobile Samsung Galaxy Note 4 SM-N910T on Net10 prepaid network.

Worked for me!!

Did you ever find out a resolution to this? I'm having the same problem -- card works in computer and other devices, but not tablet which was rooted (twrp) with supersu installed. In fact, no sdcard will work now in that tablet, formatted using gui formatter mentioned earlier or not.
