[Vibrant Q&A, Help & Troubleshooting] SociedadePsicopata:
After many weeks finding all the possible means to fix my Vibrant with a non-mountable internal SD, here some hints for future users do not waste too much time, as I did, trying to fix it.

Of course there are many "PHD"Threads, regarding this topic, in the forum, but many are kinda confusing or not for this specific mobile model.

If your recovery keeps saying that it "cannot mount internal SDcard"or Cannot mount mmcblk0p2, means your internal SD is gone and you have lost all the data on it (Blame Samsung, and its cheap hardware, for that).

First of all, DO NOT WASTE TIME TRYING TO RECOVER IT.

I have seen many people that have wasted precious time trying to Lagfix, Repartition, Flashing it to stock over and over, popping out batteries and so on, and nothing worked. You can give it a try (other posts have many outcomes). But for me it was only worries and no fun.

here`s how I definitely figured it out:

- If you`re acessing the recovery (CWR, Semaphore, Overstock, or whatever kernel), you`re good to skip the flashing process. If not, Back up all your data (oops, there`s no data to back-up :silly: - So why many posts keep saying that, regarding this issue??) and flash it ODIN back to stock (links and files of how to do it can be found within the forum). I used the SGH-T959.tar and 802.pit file. No need to check any of the options (repartition, reboot,...), but no problem if you do.

- If you have stock or not, remove your external SD card from the phone and plug it into your computer DIRECTLY (do not do it remotely via USB-Phone connections). Download your preferred partitioning software (I use Mini Tool Partition) and reparation your SD card in 2 blocks (one FAT32-Primary and the other EXT(4 or 2)) - Do not need to warn you`ll lose all the data in the SDCard - Doesn`t matter the sizes, but be sure you`ll have, at least, 1gb at each side (otherwise you may not have enought memory for apps and midias). To learn how to do that, please rely on specific posts on this subject.

- Copy your preferred ROM and GApps ZIP file on your FAT32 SDCard partition. Copy also this very handy zip file from this genius guy:laugh: (It will spare you from the annoying task reedit the vold.fstab file and also the risk of screwing-up the installation process and have to start all over, and over - for me was like 200 times:confused:). Plug back the SD into the phone and turn it on recovery mode.

- Once you`re in recovery mode (see how to do it over the forum as well), choose the specific ROM for your kernell. I suggest always to use the CWM 5.2 because it handles most of the android versions. And also prefer the Cyanogen Mods, since the SlimBean rom has caused this whole issue with my phone (Yes! The ROM can ruin your device, so choose it wisely).

- Chose install from SD card and then install zip from SDcard. Install your ROM, GApps and the linked vold.fstab.zip file, in a row. If you have an error message during the installation (with a warning sign over the robot), it means you`re under an incompatible kernell and must switch to the one compatible with your Android version (see details about that in the forum as well). If everything installed correctly, reboot the phone and have fun.:D

- "Voilá", you now may have a fully operating phone again. The bigger the SD card capacity you choose the better.

Hope to have a simple clear summary of how to fix this not-cool-at-all Samsung bug on Vibrants.
