[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.

ahh..this was the thing i don´t understand...but i think it´s a good tip

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

PLEASE HELP...Can't get SD Card Swapped!!

I just got a 32GB Micro SD Card for my evo and I am trying to replace my current 8gb card. I was previously running MIUI 11.26 and using clockworkmod recovery. I followed these steps because I couldn't find anything Evo specific:
http://theunlockr.com/2009/10/15/ho...-android-when-using-swap-hero-and-or-apps2sd/
when trying to format and reapply the rom i was using i received this error msg:
E:Can't mount /dev/block/mmcblk0p1 (or /dev/block/mmcblk0) (No such file or directory)
Now I don't know where to go from there. I previously had a 16GB card fry because apparently i didn't take the correct steps to get it working properly, i do not want that to happen again. Can ANYONE give me specific instructions for swapping my SD Card for my Evo?? If so I would GREATLY appreciate it!!!
And yes...this is probably rather "noob-ish" and I DID already search the forums for any help and couldn't find what i was looking for. Again any help is appreciated
Thanks!!

just copy all files from your 8g card to the 32g card pop it in the evn and you are good to go, nothing special required. Unless you are using apps to sd, then the easiest way s to put all apps back on the phone, then after switching to the new sd put them all back on the sd.

Yea I tried that and kept getting an error msg. I think there are specific steps for partitioning etc I just don't know them.

sorry if i'm misinformed but the evo has 2.2/apps2sd built in and 2.2 partitions the sd card on reboot. The article u linked i believe is for devices with 2.1 or ealier and a modded apps2sd . I have swapped many different cards and have not had to do anything that special.
Here are my steps:
1. go into settings manage applications and pull all apps back to phone.
2. copy all files/pics/vids/whatever u want to keep to computer.
3. power off, swap out sd cards, power back on.
4. phone should boot and partition sd or whatever.
5. use astro file manager and if it shows directory for sd, asec, secure then everything is good and u can move apps back to sd.
6. hook phone to sd and move all your kept files from old sd to new sd

I have seen your problem happen with a bad sd card, where did you get the 32g card. You may want to test it and see if it is actually a 32g.

Thanks for the response...just a question before i go forward with it, when i replace the card and reboot the phone, is it automatically going to boot up w/ the rom i was using before replacing the card?
Edit: Tried these steps and got stuck in bootloop for MIUI (rom i had flashed previously). Even tried to put the initial PC36IMG file on the sd card and flash it through recovery, nothing! It searched for it then says it directory cannot be found. I've put the 32gb card in my card reader on my computer and it comes up just fine, I can add files to it, format it etc and everything works, any other suggestions...this is becoming highly frustrating! Again any help is definitely welcomed!

So i still cannot seem to get this working, and I've tried doing a lot of different things and nothing is working for me, I have tried to install some sort of file manager program (astro) but it doesn't recognize my sd card, yet my phone shows it as mounted and with plenty of space available. I do not know what else to do...can ANYONE help me?

i had a similiar problem recently. For christmas I received a new sd card. At fist it didn't recognize my card. I tried to format it using my PC but I then went to my recovery (Amon RA) and clicked on the Partition SD card option.
After I partitioned, I turned on USB-MS toggle and put all my files back into the phone (including my rom zip).
I disabled USB-MS toggle, and then wiped data/factory reset, cache, dalvik-cache
Flashed zip from sdcard and violoa. It works!
try that one out.

noob needing advice

Hi folks I'm new here so go easy on me
I recently installed CyanogenMod via the installer but I mid the s-pen functions more than I anticipated so I have been looking at the different ROMs on here and decided to try Phoenix ROM. when I downloaded the ROM and super clean as described in the instructions I placed them both on my ext SD card but I can't flash from ext SD via Phil's cwm as it doesn't find the SD card it says its not mounted. Is it OK to place the 2 files on my phone root directory to flash from there or will super clean wipe them from there too before I can flash the ROM.
Thanks in advance

Anybody ???

1st...
what is your SD card ?
64 GB ?
2nd...
if you use a super clean wipe Zootscript Megawipe to clean, yes it will erase your internal USB storage.

switch off and remove battery and place the ext sd and boot up and see if it detects on phone now proceed to recovery and wipe there u can even find a ption to mount internal storage so after the wipe u can place your file to internal sd but before doing anything just verify if the mount is working and if the ext sd has detected or not

Tried that but no success still says unable to mount path no matter what I try to do withe the external SD it works fine from the phone just not during recovery. Could it be a bug in cm 10.2
How do I get the ROM to the internal SD if I mount it with recovery can I connect it to my laptop and transfer of over from it.

I've tried formating the SD card to fat32 and flashed the latest cwm recovery and still no joy with being able to use the external SD to flash from. So if I do the super wipe how do I get the zip file for Phoenix ROM or any other ROM for that matter onto the phone to flash it

well, i am not sure it will work or not,
but have you try with OTG cable + thumbsdriver/ pen driver with the rom in it to connected to your phone to flash in recovery ?
if this dont work, probably u will need a brand new memory card for sure

Well i finally got it sorted i flashed the latest cwm recovery again using the internal memory and it worked i can now access the external sd card from recovery so im now running phoeniX v14 and sofar im impressed and glad to have s-pen functionality back again

[Q] big trouble, cannot mount Ext_MicroSD (M8)

Dear friends:
I don't know what happend, but I cant mount my EXT_MICROSD Card... I flashed the phone, I format the MicroSD Card, I read a lot of threads from here, but nothing, without solution...
well... the first thing was when I flashed TWRP latest recovery (2.8.1, any else) then, microSD card stop to work. I read this treathd (the problem it's the same, but with other smartphone) http://forum.xda-developers.com/showthread.php?t=691639 I tried to make all steps, but doesn't work
I set my microSD Card into my card reader on PC and I can use it.
When I get into recovery I can't "read or mount" storage microSD or USB storage"
I'm desesperated right now... :s I don't know what it's the problem!! please help me, give me a chance to repair my error... ;__;
PD. I flash full stock ROM and I tried flashing custom ROM, well... I hace this problem 1 week ago.
NEWS: I flash GPE ROM, I changed MID at least USB Storage WORKED!... but isn't MicroSDCard and the "yellow/white" flash in bootanimation it's gone

Its not clear how you re-formatted the SD. But folks have had differing results whether they use the phone's format function, or otherwise. 3rd party formatting apps on a computer seem to work better. So give that a try.
Did you try another SD (borrow from a friend if you don't have one)? Its possible the card has just gone bad.

Hi, thanks for answer. I tried using other SD Card (in the mobile), but doen't work. I put the SD Card into a SD Card reader (in the computer) and work correctly. In that moment I formatted into Fat32, NTFS, ExFat and work fine in the PC, but doesn't work in the phone.

I recently had similar issue.. either the rom could read the sd card, but not recovery or vice versa (I use Philz).
I reformatted in Philz with default settings and now it works in both rom and recovery...
Think it has to do with allocation unit size. I can't help you with "correct" setting, but I know if you have too big or too small, it can slow down read/write speeds.
What happend when u plug in sdcard in your unit? Does it say it needs to be formatted?
I found some good read about formatting sd card here

When I plug into the phone doesn't work. (now I have TWRP recovery, do you think that Phil it's better than TWRP? maybe I could try flashing that) and... the first time doen't say to make a format. but, yesterday, when I install GPE, say that. when I push format... doesn't happen.

Im not qualified to tell if TWRP is better or not, but Philz is the one I use and it fixed my SD card issue. Just give it a try... you can always flash back to TWRP after if you want

Hi have exactly the same problem? i bought my at&t htc one m8 unlocked but couldn t ever even mount external sd card, they work well outside the phone but don t function inside it, not even recognize an ext sd card.....please someone could give some help to me?

If you try formatting an SDCard on a PC, set the block size to 512 bytes.
Are the SDCard's branded or cheaper end of market?
There was (maybe still is) a problem with SDCard's of a certain version (v10 I think) and this could be a similar thing.

Well, my final score: the SD Card was loose and disconnected inside, a cell technician repair it.

Format SD as Internal?

when i format my SD card to be used as internal storage and i place a ROM on the SDcard to install / update the Rom im on i cant locate the zip at all. Is because its formated as internal and also when i connect to my computer only the sdcard shows not the internal memory any ideas

Let me just give you an other warning, when using Custom ROMs you should not use internal storage, because the moment you decide to switch ROMs and you either choose to or have to wipe /data, strangely it will wipe and corrupt an SD card,, its weird because wiping /data doesn't touch the real internal storage but if your SD is set as internal storage it wipes it.
I learned that the hard way, I switched to a custom ROM on my HTC 10, I was using SD Card as Internal for the first time on this device in Stock Rooted ROM, the very second I wiped /data to do a clean flash, TWRP said "can't mound sd card".
The card was wiped in a weird format so it was corrupted, a 64GB Sandisk Ultra became a 16GB card that wouldn't properly mount even in windows, yes for real! even formatting in Windows 10 wouldn't fix it, I had to use a special tool from sandisk's website to repair the card.
After all of this I searched XDA to confirm this is a real issue, it wasn't just weird bad luck, so if I were you I would be careful or just switch back to SD External Mode.
The final conclusion is this feature is very nice for the regular world with OTA's but it seems in the Root world it can be a disaster, which I'm sure why you could be having issues as well.
EDIT: I forgot to mention, the last part you mentioned is normal, internal storage will no longer be accessible in Windows or even Android for you, apps can still install there though, and in the App Manager you have the choice where you want a particular app installed.

No problem, I will tell you my set up if it helps you, I use SD as External, all my Music, Photos, Videos, Game ROMs(SNES, N64, etc), TWRP backups, any ROMs or flash stuff is all on the SD.
My internal storage is usually never touched by me file transfer wise, all apps and other caches and such are stored there by force but I still have a good amount of space because of the SD help still.
And I have a bit of apps, including all the big file sized GTA games, Real Racing 3, etc.
Good luck on what you decide is best for you!

hey there. How should I format my SD card? Ext2/3/4? size? What's the best choice? Got a 128gb card
Thx for reply
