    Yes, there's a internal 4gb sd card class 4 inside every tablet of the xx24 series and yes it it replaceble. But be very carreful, and run antutu benchmark on the sd card that you want to put inside the kyros to see if the sd card has the at least the same write and read speed as the internal sd card.

    I tested with a 32gb and a 16gb on a 1024. Both worked, but I went with the 16 because it was the faster card.

    Was there anything special you had to do to prepare these cards?

    I ran the AnTuTu tests and internal read/write tests scored 61/58.

    External 32gb read/write scores: 91/40.

    So my current external card has a faster read score.

    Spook_Man, the metal thing on top of the internal sd card is soldered and keeps the sd card in place. When I replaced mine, I forced it/break it. I did not solder it back but still kept the metal and just put a tape on top of the metal. Hopefully it will stay in place.

    Nothing special to do to the new card, just insert and flash like normal.

    I didn't have the same luck.

    I changed the internal sdcard with 16GB card and reassembled everything, then it wouldn't boot up. It hung up at the Android logo.

    I have tried reloading GingerLF version 1.5 a couple of times but then internal sdcard doesn't show. It just runs from the ex. sdcard.

    Most things seem to work but it is low on memory.

    Anyone have an ideas to get my int. sdcard working?

    @merl, as Kairnage says, I would get another 4gb microsd card and flash your system with the 16gb card in your system. You could use Steev's Alldro2 CFW or even the Coby stock rom. Just putting in a blank card into the internal memory slot won't allow the system to work properly; there's missing files. Re-flashing will create the proper files/folder/partitions for the 16gb internal card.

    I hear what you are saying, but that's what I have done several times now. I have reflashed using GingerLF, and a couple of other CFWs but still no.
    I have tried new sdcards for the CFWs and int. Sdcard and I have tried putting the 4GB card back in. It seems I must have screwed something up.

    @merl: Wow, sorry to hear that nothing is working for you. Is there anything I can try to help you with to get it working properly? Steps to complete the job, etc?

    After waiting an hour and half for a DD raw copy within a Linux virtual machine to finish (which it never did), I just did the flash of the 32GB SanDisk which I bought from Walmart when I first got my 7024 (believe its a class 2); used Steev's Alldro 2 1.3 CFW (http://www.androidtablets.net/forum...13-cfw-mid7024-based-alldro2-gingerbread.html). I was using this 32GB card as my extsd for the tablet. Tablet is now showing Nand memory at 27.8GB total space with 27.8GB available and 1.37GB internal available in internal storage.

    Got a bit scared for a second after putting the tablet back together. Power up, Kyros logo would only be shown and side buttons would stay lit. Found that the tape which holds the metal memory connector down was loosing it's holding abilities; memory wasn't seated all the way down. I had to re-tape it and once the memory card was being held in place properly, it booted up, QUICK! 13 seconds from when the boot animation starts until I get to the unlock screen! As my previous post stated, the AnTuTu memory Read/Write scores were 61/58 with the stock 4gb SD card and 91/40 with the extsd card. Slower write, but significant higher read score and it does show in boot-up time.

    Merl, not sure if you have tried this. Get a magnifying glass and look carefully around the memory slot. If you used anythig metal to remove the tape you might have damaged a trace for the slot. Long shot but....

    Well, this is may latest attempt:
    I downloaded Alldro2-1.3_7024.zip and extracted.
    I opened the case, pulled the 16GB sdcard and formated it using HP USB Disk Formating Tool. Put back in the MID1024.
    Formated the 32GB with the HP USB Disk Formating Tool, and then copied the Alldro2-1.3_7024 files to the 32GB sdcard.
    Put the 32GB sdcard into the extrenal sd slot , held down the silver button while powering on until the blue text shows up.
    It goes through the Update process and says it's initalizing the internal sdcard and show the capacity to be 32GB. It finishes installing the file and patches then powers off.
    I pull the 32GB sdcard and power on the device. The Logo screen comes up and the system hangs.

    If it is saying 32GB then it is not seeing the internal at all. If you have looked for damage then you could try better tape, or look on amazon for Xbox heat sinks. They are a soft pad that you could place on top of the tape and when you put the case back on it will press the holder down.

    Ok.. Just want to verify; so you have two SD cards a 32 GB and a 16 GB card. You want to replace the existing 4 GB internal with the 32 GB card. Some of it may seem picky and redundant, but I just want to make sure everything is done "by the book" and the way it's been passed down by others on the forums. ha-ha..

    As with all other CFW jobs, "Disclaimer (borrowed from lfom): This custom firmware was tested on a MID7024 and worked fine, but you are solely responsible for its use. If it bricks your tablet you've been warned."

    1. Download and install SDFormatter; https://www.sdcard.org/downloads/formatter_3/. I've never had any issues with the simple windows formatter, but others have used this program and haven't had any issues since using this program. Plus you mentioned you're using an HP formatter. It's possible this is putting HP's twist on the SD card; hard to say but some companies have their own "standards" for doing things.

    2. Open and remove the existing memory; as Kairnage suggested, look to see if there's possibly any damage done to the memory slot. I used the follow documentation from MarioCG to open and remove the existing 4 GB memory; http://www.androidtablets.net/forum...recovery-recovery-image-mid-7-8-1024-a-4.html

    3. One at a time, put the 16 GB and 32 GB cards into your computer and format them using SDFormatter. I'd do the 32 GB card first, take it out once the format is done and then the 16 GB last so that you can keep in the computer to copy over the ROM files.

    *NOTE* - anytime you remove these memory cards from your PC, ensure you do the graceful removal; e.g. right-click "Safely remove hardware and eject media" icon in your task bar and select eject for your memory card, etc.

    4. Download the latest Steev Alldro2 v1.3 CFW Rom. http://www.androidtablets.net/forum...13-cfw-mid7024-based-alldro2-gingerbread.html

    5. On a whim, also download the latest stock firmware from the Coby website. This link is for the 7024 firmware. http://cobyusa.com/files/software/MID7024-Firmware.zip

    6. Carefully put the newly formatted 32 GB card back into your tablet and put the internal components back together (tape, ribbon cables, etc.) and just sit the back cover on; don't press it firmly down in case you need to open up the tablet again to remove something, etc. Flip the tablet over so you see its screen.

    If you want to just flash to the CFW, then jump to step 12. Beginning with step 7, we'll first install the stock firmware and then update to the latest CFW.

    7. Next, unzip the Coby stock firmware (MID7024-Firmware.zip) and copy its unzipped contents onto the 16 GB card. Ensure you do the graceful removal of the memory card and place it into the external memory slot of the tablet.

    8. Hold down the "home" key (the front circular key) and press and hold the power button until you see the Coby/Kyros logo and the blue text stating that it's going to do a ROM update. When you see the blue text, release both buttons.

    9. As with the custom firmware, it'll begin the process of resetting up your system with the stock rom. Hopefully the system will report during the firmware update, that the internal memory is 32 GB in size. It may power off and turn back on during the process but it'll shut down once it's done.

    10. Once the flash is done, I usually then remove the external SD card prior to first powering on the tablet. If the system sees this memory, it'll try to use it and copy files to it, etc. You can use it later, but for first power-up, remove it. Press and hold the power button until you see the Coby/Kyros logo. HOPEFULLY if everything went well, you'll be greeted by the Android Froyo unlock screen and then when you unlock it, be greeted by the default Coby layout, installed APPS, etc. Next, let’s update this firmware to the latest Alldro2 CFW; Power off your tablet.

    Also, give it time on the first boot up. I usually let it sit and do its thing for at least a minute prior to trying to unlock it, etc.

    If everything looks and works correctly, press the back of the tablet back together. You shouldn't need to open your tablet up again.

    11. Put the 16 GB card into your computer and format it again using SDFormatter.

    12. Next, unzip the latest Steev Alldro2 v1.3 CFW Rom (Alldro2-1.3_7024.zip) and copy its unzipped contents onto the 16 GB card. Ensure you do the graceful removal of the memory card and place it into the external memory slot of the tablet.

    13. Hold down the "home" key (the front circular key) and press and hold the power button until you see the Coby/Kyros logo and the blue text stating that it's going to do a ROM update. When you see the blue text, release both buttons.

    14. It'll begin the process of resetting up your system with the CFW rom. When I did the firmware update, the update reported that the system saw the internal memory at 32 GB; hopefully you too will see this. It may power off and turn back on during the process but it'll shut down once it's done.

    15. Once the flash is done, I usually then remove the external SD card prior to first powering on the tablet. If the system sees this memory, it'll try to use it and copy files to it, etc. You can use it later, but for first power-up, remove it. Press and hold the power button until you see the Coby/Kyros logo. HOPEFULLY if everything went well, you'll be greeted by the Android Gingerbread unlock screen and then when you unlock it, be greeted by the layout, look, etc.

    Also, give it time on the first boot up. I usually let it sit and do its thing for at least a minute prior to trying to unlock it, etc.

    If everything looks and works correctly, power off the tablet and press the back of the tablet back together. You shouldn't need to open your tablet up again.

    If you're still having issues, I would look at the SD cards you're using as the main culprits; e.g. the system sees the 32 GB card during flashing, but then the system locks up at the lock screen, etc. I've mainly used SanDisk SD cards and haven't had any issues. I bought a 4 GB yesterday from Wal-Mart for $10 and this will become my main flash external memory. I also bought a 32 GB SanDisk from Wal-Mart when I first got my tablet and this is what is working in the tablet just fine right now. I saw them on sale yesterday for $49 as well. I believe both as Class 2 SD cards.

    And then as Kairnage suggested when you have your tablet open, look to see if there's possibly any damage done to the memory slot.

    And when you're putting the tablet back together, ensure the metal memory tab is taped down and holding the memory in place. I had this issue where I put everything back together and after powering it back on, it stayed at the Kyros screen. The tape holding the metal piece down came loose and the memory wasn't seated correctly.

    I hope this write-up helps you and maybe helps someone else if they want to tackle a memory upgrade project for their Coby 7024.

    Also, if you're using a custom rom and MAC address filtering on your wireless router, following lfrom's tip http://www.androidtablets.net/forum...our-mac-address-across-firmware-installs.html to keep using the same MAC address for all your custom rom updates. This works well and I've used this tip for all my updates from Alldro2 version 1.1 SP-1 to version 1.3.

    Thanks..

    Just a couple of thing to add. Minimum Class 4 on the SD card. Particularly if you are going to watch any high res movies or TV. Speed counts. For flashing bigger isn't better. The microsd you flash from should be 4GB or less. Not that you can't use bigger, but you are likely to have less problems. If you use bigger, try padding the card add a couple of large files to the card with the flash files.

    To Whom It May Concern;

    I have tried ALL of the above suggestions (Thanks guys) but have had nothing but bad luck.
    At one point I did get it to boot up and see the internal SD, load the updated Coby Firmware and go to the unlock screen, but the screen would only respone for a few seconds at a time. (totaly un-usable) I was able to get past the unlock screen (kept trying the slider until I got it) and the buttons all worked (could open Browser, menu, go back, search) but the screen would only for a few seconds (3-4).

    I went through the "Process" again, but it hangs at the ulnlock screen again (screen never works)

    I powered it off and back on, now it does not see the internal SD or the external SD. It slowly goes to the unlock screen and hangs.
    It shows "Low Memory" in the notification bar but the screen will not accept any input and the buttons are lit all the time.

    Holdin the Home and Power no longer start Recovery. The buttons light up and then everything powers off.

    I feel I have waisted enough of everyones time on this. They still have another one in the store... looks like it may have my name on it!

    Thanks for all the help, but I am giving up. This will still be Back Burner project, but I am going to get a new one.

    Is the Alldro2-1.3 the CFW to use on MID1024 or should I use the GingerLF-1.5?

    Thanks again.

    @Merl, sorry to hear it didn't work for you. Any issues using the stock 4 GB memory, reflashing, etc?
