Alright, everyone. I have Link2SD working on my BPDN 9 inch and have 80mb of free space on the internal drive and 100 mb of apps on the SD card. What worked for me should work for anyone with a BPDN 9 in (R90L200) hacked with Roebeet’s upgrade.

I must admit I wouldn’t have a clue what to do if not for the help of Kierrok on xda developers forum.

Before I give the full instructions, I want to make sure that other BPDN 9 automatically have the same drive names for the SD card as mine. If they do not, then I will have to modify the instructions a little.

These instructions are intended be very thorough so that even the most technophobic of us can follow them. Sorry if I am insulting the intelligence of more advanced linux programmers amongst us. If you are comfortable installing Roebeet’s upgrade, you should be fine with these instructions. If not, get someone more technically inclined to help you.

Could someone do the following so I can make sure the drive names are the same:

-have Roebeet’s upgrade installed
-partition an SD card as FAT32 on both partitions (google it if you need instructions). The first partition should be the larger of the two. The 2nd partition will be where apps are stored from Link2SD. The first partition will be where you store music files, ebooks, etc for use in apps on the tablet. 400mb for the 2nd partition should be plenty of room. I believe the largest SD card the BPDN can take is 16gb (**I think** - correct me if I am wrong). I am using a 4gb SD card and this should be more than enough for me.
-insert the partitioned SD card into your BPDN. If you get an error that the SD card is damaged, try another card. One of mine gave this error, but the other did not. You are on your own researching what to do if all your cards say they are damaged.
- If you do not have a terminal emulator installed, install one from the market. I just used one titled “android terminal emulator” by Jack Palevich but you are free to use whichever one you want. If you choose an emulator other than “android terminal emulator”, please contact the maker of the emulator if you do not know how to use it. My instructions will specifically for ‘android terminal emulator’.
- In the terminal emulator enter the following commands at the command prompt (it may be a ‘$’ or ‘#’). You do not need to capitalize the letters. Lower case is fine. There is a space between ‘cat’ and ‘/proc/partitions’. No other spaces, though. Press [ENTER] after each line – these are entered one at a time.

Su
Mount
Cat /proc/partitions

When you enter these commands, you should get text like this on the emulator:

Email this text to yourself in the emulator by going to the emulator menu, then ‘More’, then ‘Email to’. Paste the full text from the emulator in a reply to this thread so I can check that your SD card is labeled the same as mine.

You can then close the emulator window by going to menu, then ‘Close window’. Simply pressing the ‘Home’ button will not ‘close’ the emulator. It will stay open and you will see it in your notification bar.

Once I can confirm your SD card does or does not get labeled the same, I will post full instructions on how to get Link2SD working (and it works even after reboots).

Ok. Good news and bad news. I think I have enough info to confirm other people's BPDN 9 in follow the same naming pattern as mine for the drives. However, it does not appear your SD card is partitioned. below is the las couple lines from what you posted:

179 8 7822336 mmcblk1
179 9 7818240 mmcblk1p1

The first line shows drive 'mmcblk1' which is your SD card (an 8gb I take it?). The next line shows 'mmcblk1p1' - the first partition. There should be an 'mmcblk1p2' for the second partition. Below is the same information but for my SD card - 'mmcblk1p2' is the 2nd partition where Link2SD stores apps.

179 8 3872256 mmcblk1
179 9 3068383 mmcblk1p1
179 10 803250 mmcblk1p2

Since your first partition is mmcblk1p1, your 2nd partition will be the next increment up, namely 'mmcblk1p2', which is the same as mine. I will post full directions in my next reply.

Anyway, partition (or re-partition) your SD card. Mini Tool Partition Wizard worked fine for me. There are plenty of sites to show you how if need directions.

[NicksDad]

Here are the full instructions to get Link2SD working on you BPDN 9 in. What worked for me should work for anyone with a BPDN 9 in (R90L200) hacked with Roebeet’s upgrade.

Again, I want to thank Kierrok at xda developers forum because I was absolutely clueless until he helped me.

These instructions are intended be very thorough so that even the most technophobic of us can follow them. Sorry if I am insulting the intelligence of more advanced linux programmers amongst us. If you are comfortable installing Roebeet’s upgrade, you should be fine with these instructions. If not, get someone more technically inclined to help you. I feel I must be clear if you DO NOT follow these instructions to the letter, the fix will not work. Don't complain to me if you fubar your tablet because you skipped a step.

Prerequisites BEFORE entering the fix:

-have Roebeet’s upgrade installed

-partition an SD card as FAT32 on both partitions (google it if you need instructions). The first partition should be the larger of the two. The 2nd partition will be where apps are stored from Link2SD. The first partition will be where you store music files, ebooks, etc for use in apps on the tablet. 400mb for the 2nd partition should be plenty of room. I believe the largest SD card the BPDN can take is 16gb (**I think** - correct me if I am wrong). I am using a 4gb SD card and this should be more than enough for me.

-insert the partitioned SD card into your BPDN. If you get an error that the SD card is damaged, try another card. One of mine gave this error, but the other did not. You are on your own researching what to do if all your cards say they are damaged.

- If you do not have a terminal emulator installed, install one from the market. I just used one titled “android terminal emulator” by Jack Palevich but you are free to use whichever one you want. If you choose an emulator other than “android terminal emulator”, please contact the maker of the emulator if you do not know how to use it. My instructions will specifically for ‘android terminal emulator’.

- install Link2SD.

Once you have all of the above completed, then you can do the following:

- In the terminal emulator enter the following commands at the command prompt (it may be a ‘$’ or ‘#’). You do not need to capitalize the letters. Lower case is fine. Spacing in each line is critical!! I would suggest copying and pasting the code below into a text document so you can make sure you get the spacing right when you type it into the emulator. Press [ENTER] after each line – these are entered one at a time. The second command is to clear out a file if it exists, if it does not exist you will get an error stating it does not exist. Don't worry if you get a message stating that does not exist. Just continue on. I included this just as a precaution. The other lines below it create the file with the correct code to 'mount' the 2nd partition of your SD card.

su
rm /system/etc/install-recovery.sh
echo '#!/system/bin/sh' >> /system/etc/install-recovery.sh
echo 'sleep 2' >> /system/etc/install-recovery.sh
echo 'mount -t vfat -o rw /dev/block/mmcblk1p2 /data/sdext2' >> /system/etc/install-recovery.sh
chmod 755 /system/etc/install-recovery.sh

Now close the terminal emulator window by going to menu==> close window and reboot your tablet [press & hold the power button until you are asked if you want to 'Power Off' and select 'Power Off'. Once the tablet is completely off, press and hold the power button again until the light above the screen flashes green, then release the power button, and let the tablet start up.]

Go into Link2SD and select an app you would like to move. As long as it IS NOT a system file and you followed the instructions above, the button to 'Link' the app will be enabled. Click the button to move the app to your SD card. Repeat and rinse until you have all the apps moved that you desire.

If this did not work, I would say you made an error. I am not a linux programmer to diagnose all the goofy things that can go wrong. If you want more details on the steps I took, look at pages 244 to 246 of the Link2SD application thread on the xda developers forum. If you have something crazy going on, these are the people to ask. Of course, I will help if I can, but the instructions above should set you up.

Enjoy!!

[NicksDad]

I just found an unintended consequence of using Link2SD.

I don't know if the developer intended this or not, but now when I install pay apps from the Android Market and move them to the SD card, I guess the tablet sees that as uninstalling the app, so I immediately get a refund from Google. It's done this twice so far. So I am getting all apps for free on my BPDN.

[jbreaker]

Maybe someone can offer me some advice on getting Link2SD working correctly.

NicksDad's method mostly works, but not completely - it seems like my PDN takes too long to recognize the SD card @ boot, so the automatic mount fails, and Link2SD gives the mount script error. If I manually run the install-recovery.sh file, Link2SD works correctly, and I can move apps, but when I reboot the mount fails and the apps disappear.

I tried adjusting the sleep in the install-recovery.sh, which sort of works - the mount does occur automatically, but the delay still breaks the apps because I guess the device has already registered the installed apps before the SD partition is mounted, so it still doesn't see anything installed there.

I've tried 3 different SD cards in case it was a card or speed issue, but got the same results on all of them.

If anyone has run into a similar issue but found a way around it, I'd love to know at least what direction to look in... It's frustrating to get close but not be able to actually get it working.

hi Nick's Dad
I partitioned an SD card, (2 fat32 partitions) had the roebeet "Polaris file" on it to root my pandigital 9 novel, then after successfully flashing got link2sd and terminal emulator from the market - followed your programming instructions - when the device rebooted, it successfully read the SD card (no damaged card) but I noticed that the side buttons (arrows, home, menu) no longer work while the SD is in the slot - the Link2SD program displays all apps and offers to link non-system apps (angry birds) to the SD card but then I get an error message - "su:access granted, courtesy of www.madicandroidapps.com mkdir failed for /data/sdext2/data I/O error"

so somehow it is still not mounted... any ideas?

halle-friggin-leujah - third time around it seems to have worked - 3rd time I made sure the SD was blank (previously had the polaris dat and other files on it) - or maybe I just missed a space somewhere... anyway, thanks

[Newbie1975]

A huge thank you to all of you ladies and gentlemen. I got link2sd working and a root rom this thing has trully come into it's own in the last month.

[d0zs]

Thank you very much NicksDad, the instructions were easy to copy & paste into adb shell.

When I run the install-recovery.sh script manually it works perfectly with Link2SD, but I'm having a problem with it auto-mounting on boot.
I'm guessing it's because when the device powers off, the SD card needs to be reinserted so android can "prepare" and mount it. I'm curious how you're able to get that script to mount automatically to the SD card on boot, even though the SD card needs to be manually inserted after every restart?

edit: Got it working using a different SD card. Even though it didn't say it was damaged, for some reason it needed to be manually mounted, with this other SD card it mounts automatically on boot.

All instructions work well have market and link2sd running smoothly. You want youtube type app download from market or install videohub through sd card pick mp4 high quality streams videos smoothly amazing no buffer pauses at all actually its a better apk than youtube dont forget to pick mp4 high quality after you search for video. with all these mods and apk this little ereader is more tolerable and FYI to run games that do load up smoother try lowering graphics in settings of game. GL to all patience is a virtue. Follow instructions to the tee it will work.

Hey NicksDad,


At the request of brunog (in the Alternate FW thread here: http://www.slatedroi...post__p__395700 ) posts split and made into your own topic.

Nice write-up and thanks for sharing.

I am a noob so please excuse any dumb questions. I have black 90L200 with S6410_PP2_PD_2010_10_29 Firmware. Is Robeet's upgrade on this site. And how about the emulator and partition tools?

[3du]

Many thanks for all the effort and input. I have followed the instructions and voila!

Works on my Black Canadian Model#PRD09TW-R90A200, HW Platform RD201-2GB-W with 32Gig SD

excellent work!

cheers!

PS: The SD card reader in my PC didn't recognize a 32G card so I plugged it into my HP camera connected via usb to my PC and used SuSE linux partition tool to setup the SD card and format it. You have to delete the existing partition on the SD and then create two new ones.

Ladies and Gentleman,

I am a first time user/hacker of android devices and I have to say that this fix was spectacular! I managed accomplish it on my first, very first try! Thank you so much for saving me on this one! I think I just may have to get more into all of this! I didn't want to send this tablet back because my boyfriend bought it for me as a birthday present and he is absolutely NOT tech savvy in any fashion! So you saved me!
Thank you all for your absolutely wonderful instructions!

[Newbie41]

I have followed all the steps (many times in fact), but still can't get Link2App running. Keeps saying I need ext2. I've tried a 32GB card, an 8GB card, formating the card with Fat32 for both partitions, with Fat32 for one partition and Ext2 for the second, and with Ext2 for both partitions.
I have checked to make sure the tablet is rooted and that Robeet's ROM update is installed.
When I check the status of the SD card, I get a readout for the first partition (when it is Fat32), but nothing shows up for the second.
If I need to provide more specific information, please let me know and I will be happy to do so.
At this point I am at a loss of what to do and would appreciate any and all help!
Thanks.

[ennok]

Just a little info on the damaged sd card issue. Using information I found on other websites there is an easy way to fix the novel from saying the sd card is damaged after you've created the 2 partitions on it.

It's just a matter if using windows error-checking program to check the sd card. It won't find anything wrong but the PDN won't say the sd card is damaged. This worked for me with 2 different sd cards.

Make sure you only have "automatically fix file system errors" checked, and not the scan for bad sectors(not sure if anything will happen but why take the chance)

[hrupp]

I'm new to the boards thanks for all this work and information, I joined Slatedroid because I now have a R90L200 and wanted to get the most out of it, Can't get Link2SD to work on this PDN, I've followed your steps exactly and the SD card and partitions show up fine, both formatted to FAT32 primary, when I open Link2SD and it asks me to select the filesystem I select FAT32/FAT16 and it says:

Mount script cannot be created
su: access granted, courtesy of www.
magicandroidapps.com Usage: mount [-r] [-w] [-o
options] [t-type] device directory

any insight? Perhaps there's another way to utilize the internal 2GB better so I don't HAVE to get Link2SD working?

Thanks so much Android pros!

[galtario]

just bought a R90L200 a few days ago and did the ROM update.
having access to the market is great. having no space to install is not.
so a big thank you for this very helpful info.
