Micro SD Card not mountable or detectable after installing Custom ROM - Xiaomi Mi A1 Questions & Answers

Hello! I own a Xiaomi Mi A1 and it became really buggy so I chose to switch to a Custom ROM. I installed Pixel Experience PLUS and everything works fine except the fact that now I cannot use my Micro SD Card anymore. I cannot mount it in TWRP (it says MicroSD 0mb), and it isn't detected by any other device I tried to plug it in. I really need help for this situation since I had some useful stuff on the card. Thank you!

[Q] Is it possible?

Hey. I have owned my Wildfire for a week now so I am still a noob. I wanted to know if it's possible to install a custom ROM on the wildfire without an SD card so basically do it through USB. I have seen some phones can do it with Amon RA recovery but I don't think it is possible for the Wildfire.
Thanks.
Dont think it is although why would you want to do it without? The wf comes with a sd card

Because when i put my SD card in the adapter and put it into my laptop it cant open the card and asks "do you want to format" and when i choose yes it says "unable to complete format" so im screwed with that SD card
Use paragon partition n look on YouTube 4 a video that will sort it out n will fix that error

Still dont work its not even showing up on my computer now ive probably ****ed it somehow but on my phone it says 1.83gb free space. weird.
Dose paragon partitioning show ur sd at all if not erm check to make sure ur SD card reader is ok bu using a different SD card
if paragon partitioning is showing ur sd card.
is ur SD card signed as active and does it have a volume letter as these thing will stop I from formating the SD card

It showed my SD card then when I tried to format it would only show my hard drive and plus the free version does not let you do anything to the card.
Try Panasonic SD Formatter:

E: Probably unrelated, but, make sure your card reader supports SDHC cards.
1.What happens when you connect the phone via USB and choose mount as disk drive?
2.When you use the SD card adapter, and right click on the SD card's drive letter if there's an option to "open as portable device" try that also try updating your laptops card reader drivers.
3.Use bluetooth to transfer the ROMS?
4. If you're already rooted, try formatting SD card via ROM MAnager.
As far as I know you cannot install custom firmware (a "ROM") without an SD card.
You don't have to use your SD card directly from the computer to install custom firmware. You can use file storage mode on your phone's USB connection or adb to access your SD card through your phone on your computer.
To install CyanogenMod with the help of adb, follow the steps in hxxp://wiki.cyanogenmod.com/index.php?title=HTC_Wildfire:_Full_Update_Guide and put the update.zip into the root of your SD card with this command:
Code:
adb push update-cm-6.1.0-buzz-signed.zip /sdcard/
You need to have your phone connected to your computer, have the appropriate drivers installed to do this and have USB debugging enabled on your phone. Documentation on adb is available at hxxp://developer.android.com/guide/developing/tools/adb.html
An alternative way to the above adb method is to enable USB phone storage mode when you connect your phone to your computer and transfer the update.zip file to your SD card.
Hi guys thanks for all your help I have fixed my problem. All I did was use a windows 7 laptop and it worked.

Is it safe to unmount the SD card on an SD build?

Sorry if this is a n00b question... but I've been able to unmount and remount the SD card in my HD2, or connect it to my computer via USB (which unmounts it on the phone side), all while running Android from that same card.
I'm wondering if this is safe to do, or if the only "safe" method is shutting down Android and rebooting into Windows Mobile. After all, the 1GB data.img and the Android system are both kept on the card, so if it is unmounted, you'd think the system would crash or otherwise corrupt data...
Thanks.

I do think the system would crash or be corrupted because if all the files are running from the SD card and then it is removed, then all files would not be accessible causing the system to crash or even worse - corrupt data. Whenever run it from the SD card and connect it to my computer I use the app called "Dual Mount SD" which allows me to still access my SD card (from my phone), which means the android files on the SD card can still be accessed by the phone for the system to still run. I believe this way is the safest.
I read somewhere that someone removed it and nothing happened, but take it from someone who tried it: Do NOT remove the card from the phone when it's running android. and unless the developer specifically says that it's safe to connect his build through diskdrive mode do not connect it that way as well!
I'm using the above mentioned program and it works fine. Music and other media files will be recognized by the music app only after you rescan the card using any free tool available (search the net/market for a tool to rescan the card on android) and that's all you need

[q] urgent help needed!!

Ok, I have CWM and I can access it. I cannot read from my External SD Card to install a rom. I can access my Internal SD but I do not have a rom in there.
I cannot boot into the previous ROM since I erased everything and when restarting I get boot loops. I need the tablet to get back to work tomorrow.
Any help would be greatly apreciated.
I have a ROM downloaded in my PC but when I connect the A500 to the PC (via USB) I cannot mount it to copy it there and flash.
HELP please!!!
What version of CWM do you have. I think the new one can install ROM from USB drive. Also try reformatting the SD card in a PC in FAT32, some time its just that and some time tablet is picky what SD card it can read and what it cant.

I was able to put the SD Card from my phone and flashed the new rom. The tablet is sill not recognizing the SD Card though. I put it on my PC and it wont detect it (cant format it that way). I put it on my printer and I am able to read from it but I cannot format it. It tells me that is right protected.
I need to find another way of formatting it.
Thanks for your help.
I suggest you get a new sd card. Clearly the one you're trying to use is not working.
I'm not even sure if you can "write protect" an SD. Maybe something on the micro SD adapter perhaps (switch)? Or an option in Windows Explorer (check the sd's "properties". If it says "write protected", then turn it off.

Can't restore sd card

(Sorry for my bad english[emoji14])
Hello, i bought a new sdcard just yersteday. Right a hour ago, i've plugged it in my P8Lite and it was working well. Then i decided to create another partition(ext4) to link my obb app files with Link2sd in my sdcard via pc. Everything gone well but when i've put it in, my phone told me that the sdcard is broken and i need to restore it. When i try to restore, it fails and shows me this message:
" 'command 118 volume unmount public:179:129' failed with '400 118 command failed' "
I've tried to restore it with my pc, change file system to: ext2-3-4, FAT and exFAT, i've tried to wipe it but still nothing. My pc detects my sd (cause i've an adaptator for pc) and i can put files in, but with my phone i can't do nothing. Does anyone have this problem too? Thanks to anyone that wants to help me.
My phone specs:
P8Lite B564 with root and xposed
The problem is that you need to format the SD Card to FAT32. The other problem is that windows natively only gives you the format to FAT32 option on 32GB sizes and lower. What you have to do is download a FAT32 formatter and put your sd card in your pc using the adapter and format it completely to FAT32. Good luck hope I was able to help you

No format on SD card after marshmallow upgrade

Hi, I'm trying to find how to solve this problem with no success.
I got Bliss Rom with marshmallow and i formatted my sd card as an extension of internal memory. Something that marshmallow allows.
I got back to stock system and recovery in order to upgrade officially from stock but, the system doesn't recognize the format of my sd card, suggesting to give it a format.
After that, system keeps on not recognize my sd card and I'm stuck.
Do I have to format it taking it out and accessing via a cardreader to manage file system or there's a way to solve this?
Thank you in advance...

No success. There are 2 partitions that cannot be modified. I'm stuck...:crying:
I just [RESOLVED] an issue after inserting a brand new SanDisk 128GB microSDXC sd card.
The Honor 5X will format the blasted thing to exFAT which refuses to open up in my Windows 8.1 Laptop to access folders and the like. A try to format to FAT32 did not have that available either. (Windows only showed NTFS/(default) exFAT)
So what i did was grab this SanDisk formatter
Code:
http://www.verbatim.com/includes/binary_details.php3?show=1&id=840
and in an instant my formerly exFAT transformed to the more easily PC accessible FAT32!
Now it shows up perfectly whenever plugged into any PC via USB and you can feel free to reach your SD Card contents manually to your hearts content.
No need for Huawei's (in my opinion buggy) HiSuite which i find sorely lacking and too much wasted time with Import/Export stuff.
Hope this helps someone, anyone who thinks that they absolutely must use Honor's/Marshmallow's own formatting to exFAT.
