Hello, I am on an HTC One V running PACman ROM 15.3, with the kernel JmzPrimoC+.
I started having this problem a couple weeks ago. It would randomly unmount my SD card saying 'SD card unexpectedly removed'.
This started to happen more and more often until it would say that as soon as I put the SD card in.
I did a factory reset, which helped for about 5 minutes before it started happening again. Now, more recently, it started saying 'Damaged SD card. SD card is damaged. Try reformatting it.'
I put it in my computer (which doesn't show anything wrong with it), and did a full format. It didn't help at all.
This problem is happening with both my regularly used SD card (SanDisk Ultra® microSDHC™ UHS-I 32 GB (the red and grey one)), and my ordinary SD card (8 GB class 4 Kingston).
I don't think this can be a hardware problem because when I boot to recovery, TWRP recognizes it perfectly.
But I don't either see how its a software problem, because a factory reset should have helped...
Please help me, any help will be greatly appreciated.
Maybe its a bug in the rom?

Hhmmm...
Good idea. What other ROMs work with JmzPrimoC+ kernel? AOKP?

OK, update, now TWRP won't read the card! Either card!
Now I'm getting really nervous...
Does this mean it must be hardware?
Is there ANYTHING I can do now?
Please help!
Wow, I screwed up really bad.
I was gonna use TWRP to flash a new rom, so I did a factory reset, and then started flashing the rom.
But in middle of flashing the rom it was interrupted. So I rebooted, rereset, and then I realized... it's not reading my card.
I can boot to bootloader and recovery, but that's it. No OS. I'm screwed.
Is there ANYTHING I can do?
Is it possible to flash a rom over USB? Or SOMEHOW get my card working again?
Just enter recovery and use adb sideload to flash a ROM.

But I need an SD card in order to use ADB sideload!
It fails every time because
Code:
E:Unable to mount /sdcard
Is there ANY way to do this without an SD card?
OK, I was able to do it following this guide.
I flashed the latest version of PACman. Still rejecting my SD card though.
I guess it's a hardware issue. Too bad my warranty is void from bootloader unlock :\
Try to partition SD Card in recovery
I am facing same issue and I came across this thread while looking for solution. Here is what I tried. That resolved issue for five minutes and then damn! same issue again but someone can find possible fix using the info here.
HTC One V rooted, currently running MIUI 3.1.2 with JB 4.1.2
Sandisk 8 GB SD Card.
Firmware CWM Recovery
I was facing same issue even before I rooted my phone while Original HTC ICS 4.0 Firmware was installed. MY observation is the problem starts few months after you start using SD Card. (Insert a new SD card in your phone, it will work fine for days / months and then will start giving same error.
While I tried thousand time to remove SD card, clean slot, clean card and reinsert, it did not work. May be worked just once for few seconds. When I tried to connect phone to PC and browse SD card contents, the card was not detected.
Booted to recovery, tried to format card, not detected. Tried to mount SD card, not detected. Then tried to partition SD card in Advanced options in recovery. The available options are 128MB, 256MB, 512MB, 1024MB, 2048MB and 4096MB. Since my SD card is 8 GB, chose the largest option. Now got an option to choose SWAP partition size. Chose 256 MB. Next chose option fix permissions, you have to wait until you see message permissions fixed message on screen.
Now rebooted phone, and voila! It worked!! SD card with 3.94GB memory is detected. But what happened to my rest of 4 GB?
Tried many apps to manage SD card from Play store. Using an app called APart, was able to delete partitions on SD card and create new ones. It worked for few minutes and then again I got SD card unexpectedly removed message.
Does this info makes any sense? I am not a developer and do not know much into phones but someone who know might be able to help. Buying a new SD card is not an option here because its going to work temporarily.
Have you tried formatting the SD card with your computer?

Yes, tried formatting SD Card using computer. Works fine when connected using adapter. Not detected when phone is connected to computer.
Hello,
Currently I'm facing an issue which is quite strange.
I've bought a Android head unit from AliExpress an year ago from Greenyi.
Here are the specification:
Name:Greenyi
Voltage:12v
Size:2 Din
Model:Q7301
Memory: DDR3 1G
µC: Cortex A9 Quad Core 1.6GHz
Touch Screen:HD Capacitive 1024*600 pixels
Operation System:Android 4.4.2
Since some days, my unit is stuck into recovery mode and I tried to flash the below files unzipped and copied in the root of an SD card:
- MTCB-KGL-V2.59 (mcu.img)
- KGL_rk3188_h(20150708) (update.img)
Then, I've chosen in recovery mode the option "update from sd card".
Afterwards, mcuimg udpate was successful then my unit rebooted.
HERE, the recovery mode started again eventhough I've removed the SD card from GPS slot.
I tried again with another SD card and still I have the same issue.
Has someone met the same issue? Can someone help me please?
Best regards,
Ben.
Hi Everyone,
Last week I installed Malaysk 6.0.1 rom on my head unit. After switching off the ignition, the external SD card becomes corrupt at the next turn on. The same card in the GPS slot is flawless, and the GPS card in the other slot is corrupt. After reset (reboot) is good, but only until the first shutdown.
The Head Unit MTCD KGL PX-5 4/32 Gbyte
Anybody has experience or solution?
Thanks
Janos
Goodday, im new here and i got a problem, installing my radio that rom and its components, in the post i reach to the part when sd card 1 finishes to copy to radio, and when I am asked to remove the sd card, the radio reboots and illuminates buttons, but screen does not work. its like turned off. help me please ....
Hi everyone,
I was trying to update my mtcd gs px5 headunit (2gb) that was running malaysk ROM 1.1 (Android 8.0) to malaysk's 3.5 firmware.
I followed the instructions, booted into recovery and hit install update from SD card. It installed successfully with no errors. The next step in the guide said to wipe data so I did so. Unfortunately this led to the unit's screen going black with a flash of text every 5 seconds that reads something like "can't mount cache/recovery/last_locale".
I attempted to create a bootable SD card using the instructions on malaysk's post (https://forum.xda-developers.com/showpost.php?p=75664396&postcount=3254) but placing this SD card into the GPS slot and attempting to boot only brings up the screen in the picture attached.
I attempted to create this bootable SD using two different SD cards that are freshly formatted as well as a USB drive. I tried booting the unit using the sd cards in the GPS slot and into the regular SD slot. It only goes into that screen if there's a bootable SD card in the GPS slot.
For anyone reading this, It turned out this issue for me was caused by a faulty gps card READER.
Since I have an xtrons unit with two sd card slots (one standard the other gps) I just wired the standard SD card slot into the the GPS slot (they use the same size ribbon cable) and was able to boot from the bootable sd card.
Hope this helps someone.
