Edit: [RESOLVED] Hard brick after attempting to wipe data/cache in recovery - MTCB Android Head Units Q&A

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.

Help!! Sd Card Not Seen By Device

Help! I have an XDA IIs which was working fine for the last two years. It has a 1GB SD Card in there. I used it for TomTom all this time, with no problems at all.
A couple of days ago, I forgot to grab my device from the car as I was in a rush and I left it in the car (powered off, but with TomTom running) most of the day.
When I got back in the car, TomTom wasn't working right so I closed it and tried to re-open it, whereupon I received the nasty message "Cannot determine location of data".
To put it simply, the device no longer recognises the presence of an SD Card! It's not in File Explorer, nor under Settings / Memory / Storage Card.
What is going on?
Here's a list of what I've tried already (none of these ideas has solved the issue):
o Tried a different SD Card
o Tried a soft reset on the device
o Tried a hard-reset on the device
o After hard-reset, tried a restore from a recent Active Sync backup-to-PC.
o Downloaded PocketPC Mechanic and played around A LITTLE (didn't do anything that seemed dangerous like defragging, registry cleaning, etc)
Any help will be VERY gratefully received!
Thanks
Matt
Update... but still have problem
Quick update
I also tried formatting the SD Card. No help (I have since copied all data back onto the card and it still doesn't work).

Apparently, the motherboard your device is dies slowly.
Have you tried a diifferent sd card? reinstalling the software all over again?
Replying to Rafa1215
Yes, I have tried a different SD Card (as noted in the original post, list of things I have tried). It's a 128MB one which works fine in the SD Card reader slot on my PC (my main 1GB card works fine in PC slot as well).
Here's a further titbit of information which may or may not be useful in helping me:
I've tried several times to restore the backup-to-PC I made at the end of April (essentially the same stuff on the device then as now, luckily). Normally, when you insert (or remove) the card, it turns the screen on. Each time I perform the restore (of the same backup, over and over again), the SD Card slot actually performs this function when I insert the card again - but ONLY ONCE each time I restore from backup.
As for reinstalling software all over again... I have performed a hard-reset on the device, and tried the card as soon as it is ready to use... no luck there either.
In reply to vovaxxxx:
Is that a serious comment? The motherboard slowly dies? If that's true then this device is fit for nothing but the rubbish bin!
More ideas are welcome please, I thank you for the feedback!!
If you're luck enough to have a friend that have a BA you could test his sd card on your BA and your sd card on his BA. If his BA can read your card and yours can't read his then you have 2 situations:
1) Your sd card slot is dirty or slightly melted so you have no good contacts, try to clean it.
2) Time to buy a new phone or try to buy a new circuit board for your phone but for the price I think is better you get a new phone.
Edit: If you have $100 you can get a new circuit board here: http://forum.xda-developers.com/showthread.php?t=310283
search google for panasonic sd formatter or something like this, this is a lil program which is used to format your SD properly. Insert your SD card into the card reader, start the program and reformat the SD card.
The problem is within the SD card file system

If that doesn't work try
Storage Tools by softwinter.com
You can at least do a Scandisk and fix any errors during the scan
OK I formatted the SD card with the Panasonic formatting utility. (Backed everything up to the PC first, from the card!)
Still no difference. To reiterate - the SD Card(s) I am trying to use are working fine in my PC's SD Card reading slot.
I think it's the hardware (i.e. the XDA itself)... LGSilva says I could try cleaning the contacts. Any recommended ways on doing this? The slot is too small to get any kind of decent cleaning implement in there, and I can't dismantle the device because it's held together with special screws (6-pointed-star-shaped heads).
Hi
the company i work for has around 300 device and this happens every now and again. not sure if this will help but normally call our mobile network and get a replacement. it's normally the card reader in the device.

The screws are size 6 Torx bits, suitable sets of these drivers can be bought from Maplins in the UK, although you don't mention where you are located.
There is also a guide to taking the BA to bits in the WiKi and a very comprehensive one containing pictures etc. at the bottom of the WiKi page, well worth reading both before you try taking it to bits - Mike

SD card not Mounting Cyanogenmod

Ever since flashing cyanogenmod 6 I have been having several probelms
1. My SD card is not mounted and not recognized by anything. This is stopping me from accessing rom manager or making any changes.
I have tried several things including reformating my sd card and removing files just in case it was to full. I have not been able to figure out how to partition it to part fat32, part ext yet. I am running out of ideas and getting very frustrated with my phone. I have three sd cards to work with and none of them are recognized.
2. This would not be a problem if I could just go to stock. Unfortunately I can not get my pc to get me into recovery so I can preforma NAND backup or flash a different rom that is closer to stock. I think this may have something to do with my sd card not being recognized. I have also tried the workaround involving no pc but still am getting nothing,
3. I am also having issues with usb connectivity.
I think if i can either get my sd card mounted or my phone to enter recovery mode so I can flash another rom, add the google add on, or do a NANdroid backup it would take care of my problems. If any one has a great idea as to how to get my sd card to be recognized I feel that would solve most of my problems.
Thanks Brad
Hey I have the same problem!
Could you solved this sd card issue?
Thanks

Desire won't recognise sd card - Oxygen RC7

I upgraded from Oxygen RC6 to RC7, in between, I performed s-off, flashed the oxygen hboot table, resized the sd card with gparted and then formatted card. I then did a full wipe and installed RC7.
However, I can no longer see the SD card as being mounted once I boot up the desire, if I go to recovery>advanced>usb i'm able to see the the card fine and i'm able to install stuff via recovery but it seems as though the card isn't being mounted once it boots.
Also, when I connect via usb it starts charging instead of coming up with the sd card files. Tried turning usb debugging on/off but that doesn't help.
Any ideas how to rectify this?
edit: tried a different micro sd card and it's doing the same thing
Could be an issue with the ROM. You could try another 2.3 ROM.
Does your PC recognize your phone? You might a have a usb brick and have to flash the modified misc partition. Search ad usb brick modaco.
Sent from my LeeDroided Desire HD
managed to sort it in the end, formatted the card in recovery then plugged it in and it came up with a dialog box in windows saying format the card (again), after which it started detecting the card again.
At least that's what I think it was anyway

[Q] Finally reached a problem I cannot fix on my own, please help

So my phone and computer will not detect my sd card after I dropped my phone.
Here is everything I have tried:
hard reset
sdhc micro adapter for my computer
pulling out sd card and reinserting
pulling battery and letting sit for awhile and plugging battery back in
I followed the sd card and usb fix issue found in the forums, but everytime I install the jdk the sdk installer says it is not found.
I know if I am able to format the card somehow it will fix it i think. but I cannot get anything to recognize it, or if I can figure out what single driver is missing on my phone I can figure the rest out from there.
The sdhc adapter works with the new micro it came with but not mine.
I am still able to use my phone but I obviously cant do **** without the sd card.
I have a recent backup of my sd card on my computer I just need a way to get it to my sd card and I am stumped.
Thanks for your help guys
Is there a way to force my comp to read the sd card?
Update
One thing I was just able to do was to take the micro sd that came with my adapter and my phone reads it just fine. However it is only a 2 gb. Like I said, I have a back up on my computer of everything that was on my sd card at one point. Being that my phone can read sd cards, does this help at all with somehow fixing my factory one?
Since I am now able to get into rom manager and my phone recognizes some sort of sd card. Would flashing some sort of sense ROM allow me to put my original sd card in and format it?
If all you want to do is repartition and/or reformat it, boot into recovery and do it there. While in recovery, especially is your recovery is amonRA v2.3, select the "MS-USB" option and serif your computer detects it while you're connected via USB.

I am currently using clockwork. I tried the mount unmount options in recovery mode. I have never really tried amon-ra for anything but now might be the time to give it shot.

[Help] Error flashing Malaysk PX5 Rom on Seicane PX5 Oreo unit

I'm having issues flashing Malaysk's ROM on my Seicane PX5/MTCE Android 8.0 unit (MCU MTCE-XRC).
I'm stuck at the first SD card step. After reseting my unit, the update process starts as expected but at about a 1/8 of the progress (bar), the screen simply shows "Error!!!". I need to reset my unit using the reset button.
Now I can't seem to be able to access the recovery (which I guess this is what the first SD card is trying to flash).
Unit still boot fine into Android. I just seem to have lost the recovery.
I tried the first SD card procedure with 2 different SD cards, a 1GB and a 512MB one.
Bonus question: Was the first SD card procedure necessary in my case since my unit was already on OREO?
Thanks
Yes the first card is necessary, did you replace the img file as in the guide?
