Greetings gentlefolks.
This forum has been an absolute godsend. I managed to get the latest JF os installed and as such am thoroughly enjoying my G1.
In the past, I had a Windows Mobile phone from HTC. One of my favorite applications on it was Pocket Scheme because it enabled me to write code ON my phone. I'd love to eventually spend time working on software FOR my G1, but right now I'm interested primarily in writing code while on the train, in line, etc.
As far as I know, Pocket Scheme is not available on the Android. I also came across Ruby for Android [2], but so far it force closes as soon as I open it.
So:
1. Are there any languages that are available for writing code on the android? Something with either an included editor AND repl (like Pocket Scheme) or even just an editor (?) or a repl (like Ruby for Android) would be fine.
2. What editor for making "plain text" files with any extension do you use?
3. In desperation I tried using echo to create a new shell script file the other day, and Android OS complained that the file system was read only. Can I make it r/w from within the android, or do I need to use ADB?
Thanks in advance. I tried googling for answers, but to no avail.

Well you could flash Debian to a JF build and go from there.
You can remount it as r/w from the device. I can't remember exactly what the command is but it is something along the lines of "mount -oremount,rw /dev/block/mtdblock0 /system" anyone care to correct me if that is wrong? You can also use DroidSans Tweak Tools available free in the market, just don't use the lite version

almosst correct on the command there, there is actually a space between the "-o" and "remount" so it should read
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
that would make your system partition read write, but if you wanna run shell scripts i would go grab gscript and just write them in there.
oops i typed it wrong i switched the rw and remount, it's fixed now sorry

Haha that's funny. Ive been typing: "mount -o rw, remount -t yaffs2 /dev/block/mtdblock3 /system"
But. That's just what works for me. Found it when I first rooted my phone.
I get the:
E: No Signature
E: Verification Failed
Installation aborted
no matter what update I try to apply. (I am also hung up on the G1 screen when I try to regular boot, so right now I am pretty stuck). When I home+power it also goes to the old triangle exclamation point screen rather than the cyanogen recovery (which I just installed). Any thoughts would be appreciated. I am stuck.
Hey, did you have any response to your problem? I am having the same problem with my spl update zip file, it aborts every time. Cheers
i also have this problem
Does anyone have a solution?
just did this
yea just go to the market download telnet
(go to the front of you screen press enter then type telnetd and press enter again so it could open) then
Type the following into Telnet (these commands will give you root access easier in the future):
# # mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
# # cd sdcard
# # flash_image recovery recovery.img
# # cat recovery.img > /system/recovery.img
(have a recovery image as well on you sd card)
Stuck Too !!
Sounds like I'm stuck at the G1 boot screen too, also trying too update to new hard spl after updated radio. I'm not able to get to telnet because stuck at G1 screen. I used the original root on Wiki and the recovey never took. But the Android recovery was working and letting me have root and apply updates. I was trying to flash a dRizzle hero. Directions had me update radio and spl using the link from his page it took me to haykuro's sapphire htc dream page where i did what it said, flash radio first (that took) then hardslp.
It never took and stuck at G1. Could it have something to do with the fact that i was doing this all from the downgrade rc29? Any help would great.

First sorry for my English
All credits are for zedomax, who has gotten it to work in Nexus One and for Desire is practically the same.
Sorry about "h t t p" of link adress I am very new here.
Original howto -> h t t p : / /nexusonehacks.net/nexus-one-hacks/how-to-install-ubuntu-on-your-nexus-oneandroid/
For now, I've only gotten it to work with Windows 7 and "CyanogenMod 5.0.8" and "Defrost2.0c" ROMs. The rom is important for get this works.
Practically almost all the steps are the same as in the guide of nexus one by zedomax. Well go:
Before anything, download ubuntu.zip from original HOWTO and unzip it.
Now download the updated script from zedomax.
h t t p : / /zedomax.com/android/bootubuntu
and overwrite the bootubuntu file of unzipped ubuntu.zip
1. First, you will need a rooted Desire.
zedomax say that you must have the latest version of busybox 1.16.1 but in Defrost2.0c works with 1.16.0 and cyanogenmod has 1.16.1. So we ignore this step from original guide.
2. Once you have a rooted Android phone, you will be able to run Ubuntu under Chroot.
3. Copy these six files from ubuntu.zip over into your SD card’s root folder under folder name “ubuntu“
4. Put your Desire in recovery mode. And connect it to your computer via USB.
5. I am assuming you've already installed the Android SDK (while you were rooting your phone) so let's head to your Android SDK directory and load up ADB Shell.
For Windows, go to your Android SDK Tools directory such as c:\sdk\tools and type "adb shell".
(FYI, cd is the command you can use to browse to your sdk\tools directory. For Windows, do cd \sdk\tools and for Mac/Linux, do cd /sdk/tools.
For linux and Mac, go to your Android SDK Tools directory such as /sdk/tools and type "./adb shell" or it can also be "sudo ./adb shell" for Ubuntu.
6. Once you are in the ADB shell, you should see a “#”symbol. Great, let’s start bootin’ Ubuntu right away.
7. Next, type "mount system", press enter and then type "mount sdcard". If you get this "mount: mounting /dev/block/mmcblk0p1 on /sdcard failed: Device or resource busy" ignore it, sdcard is already mounted.
8.- Next, type "cd /sdcard/ubuntu"
9.- Now we will write separate commands instead of using a script to see if something has gone wrong easily. Copy and paste each line separately and hit Enter at the end of each command.
rm /system/bin/fsrw <--(this problably return an error, ignore this)
rm /system/bin/bootubuntu <--(this problably return an error, ignore this)
rm /system/bin/unionfs <--(this problably return an error, ignore this)
rm /system/bin/mountonly <--(this problably return an error, ignore this)
cp -f fsrw /system/bin
cp -f bootubuntu /system/bin
cp -f unionfs /system/bin
cp -f mountonly /system/bin
cd /sdcard/ubuntu
chmod 4777 * <--(this problably return an error, ignore this)
cd /system/bin/
chmod 4777 *
cd /
umount sdcard
umount system
exit
Now select "reboot system now" from recovery menu of your Desire. When android fully loaded you need load up again ADB Shell.
For Windows, go to your Android SDK Tools directory such as c:\sdk\tools and type "adb shell".
Type "su" to enter superuser mode. Is very important not to forget this!
type "mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system"
type "mkdir /data/local/mnt"
10. Once that completes, type "bootubuntu" to "chroot" or boot into your new Ubuntu on your Android!
If you get the "root_localhost:/#" sign, congratulations! You've just installed Ubuntu on your Desire/Android phone!
the hardest part is complete!. From now, follows the original guide for the "nexus one" to get access to Gnome (visual desktop).
Other problems like keyboard mapping can fix it follow the original post from nexus one forum:

well, I hope this helps
thats pretty cool mate thanks ill try it out tonight when i get home from work
Thanks for this! Will give it a shot when I have a moment
Script?
Anybody fancy writing a nice script to do this for us? I'm on Holiday in Spain so I'm feeling pretty lazy.
Awesome, thanks a lot!
I'm on DJ Droid's Sense with Froyo 2.2, will try it.. hope it works! But do you know why it's rom specific? Is it because of busybox?
I tried this out, and got stuck on bootubuntu from the bootloader menu.
command not recognized. . .
everything works ok until i try to boot ubuntu from the bootloader menu.
Works great for me, SixOclock rom with busybox 1.16.2

Is anyone nice enough to break the ubuntu.zip down into the 6 files and upload separately?
good job, works fine on SetRom 3.5
someone can post screenshoots ???
?¿?The uncompressed "ubuntu.zip" has a 2Gb .img!!!

humm, are you get any error in this part?
cp -f fsrw /system/bin
cp -f bootubuntu /system/bin
cp -f unionfs /system/bin
cp -f mountonly /system/bin
and, where are you launching the bootubuntu command? You need do it from adb shell (at least until you set gnome) or terminal client directly from your phone, like better terminal emulator. Don't forget do "su" before launch bootubuntu. If it still does not work I recommend you start again the guide

First off, This is probably in the wrong space, simply because I haven't reached my proper post count. (Too much of a lurker, sorry) but I think I've found something that will make fellow D2 / D2G smile, and I couldn't help but share this.
Here is where I got the idea from:
http://forum.xda-developers.com/showthread.php?t=962974
Unfortunately, the debian-img.zip link is no longer functional (at least it was the last time I checked). No big deal, you can get it from here: Debian-img.zip.
Download that, and make sure you have your Android sdk tools installed. You will need root and busybox. Connect phone to computer, memory card mode, create folder called debian, and unpack the debian-img.zip file into the debian folder on the sdcard. When complete, switch it to charge only mode and now for the fun to begin.
Open the command prompt, navigate to sdk\tools folder, and type adb devices. If you don't see your phone listed as a device (will be a bunch of letters and numbers) switch it to pc mode, run adb devices again.
Once it shows up, type the following:
adb shell
su
mount -o remount,rw -t yaffs2 /dev/block/mmcblk1p21 /system
export bin=/system/bin
export img=/sdcard/debian/debian.img
export mnt=/data/local/debian
mkdir /data/local/debian
export PATH=$bin:/usr/bin:/usr/sbin:/bin:$PATH
export TERM=linux
export HOME=/root
busybox mount -t ext3 -o loop,noatime,nodiratime $img $mnt
busybox mount -t devpts devpts $mnt/dev/pts
busybox mount -t proc proc $mnt/proc
busybox mount -t sysfs sysfs $mnt/sys
busybox sysctl -w net.ipv4.ip_forward=1
echo "nameserver 8.8.8.8" > $mnt/etc/resolv.conf
echo "nameserver 8.8.4.4" >> $mnt/etc/resolv.conf
echo "127.0.0.1 localhost" > $mnt/etc/hosts
busybox mount --bind /sdcard $mnt/sdcard
busybox chroot $mnt /bin/bash
if ps -Al | grep vnc > /dev/null
then
echo "vnc detected"
else
export USER=root
rm -r /tmp
mkdir /tmp
vncserver -geometry 854x480
fi
exit
mount -o remount,ro -t yaffs2 /dev/block/mmcblk1p21 /system
You can't just copy/paste that whole block of code due to the busybox commands. Copy and paste one at a time. I also found that you can't make a script with that code either (please prove me wrong!) and have it work on the droid2 or d2g without errors.
Once you put in the last command, hit ctrl+c, and then open AndroidVNC, using the following data (similar to the debondroid thread):
nickname: debian
Password: password
Address: localhost
Port: 5901
Then connect!
Issues:
I have found that not only can't I use a script, I also cannot use a terminal emulator or even connectbot to put in the commands line by line. I am unsure why, but this only seems to work when I use the adb shell through a computer/usb connection.
You may have issues using USB SDCARD mode after you have run this code. This is fixed by rebooting the phone (as this causes debian to stop being run, and the img is being run off the sdcard, which is mounted with busybox into the system). Otherwise, all other phone functions work perfectly.
A neat little bonus: I found that I am able to access the internet through a browser in debian using nothing more than my 3g data connection.
Feel free to comment! Especially if someone out there can get these commands to work as a script. Enjoy!
im dieing to get this running, i have D2G running miui ics, first i cant download debian-img.zip, it wont complete download. after searching and downloading debian arm iso and renaming img i try your instructions and get hung up at
busybox mount -t ext3 -o loop,noatime,nodiratime $img $mnt
any help would be apperciated thank you
It's possible the latest ICS leak could be the problem (I had only tried this on an old Fission build, stock (both) and CM7). However, sometimes when I would reset the phone and run the commands again, it would throw me an error in the same spot you're having. It was wierd (as it JUST worked). I flashed to a different ROM to see what was up and it was happy again--but only through one power cycle. There might be a spot in this code I'm missing, but the error it throws acts as if I were trying to mount the img in the wrong loop block. This could be to the loop block already having the residual data (from the forced shutdown of the phone not allowing a tru closure of Debian), and if that's the case It would make sense if we could wipe that loop block (del and recreate it) through ADB. I haven't had time, but I'll look into it tonight.
As for the img, I'll also look into that tonight (on my phone currently).
I really apperciate the speedy reply, I'm not showing ext2 or ext3 on miui ics, do you know of a working GB rom that debian works with. I really apperciate your work in getting this going, I'm surprised its not developed by more people as the idea of having a desktop computer in your pocket is appealing. Thanks again
That's the beauty of this workaround: D2/D2G doesn't have ext3 support. That's why I had to use this method and frankly could be one of the reasons that there are those out of the blue errors that don't make sense. I need time so I can get screenshots up (to prove I'm not lying), but this will work with the img file linked.
For a good GB build, you can try the latest CM7 build at rootzwiki, or the stock GB update.
I tried again and almost everything went smoothly until i punched in "fi" and it gave me an "Unknown hz value! <80> Assume 100." i finished the instructions and tried to fire up androidvnc and tried to connect and i get " VNC connection failed! localhost" so im going to try and attach a bmp of my cmd window. i am looking into the unkown hz value but so far am stumped. "change ext of file to bmp or png"
also im assuming the debian img which i was able to successfully download is a arm distro?
omg it worked!!!! i redid the steps like i had done i was still getting vnc connection error, then i changed the address in vnc from "localhost" to "127.0.0.1" and it works!!! thanks man

Debian img is indeed for ARM. And I haven't seen that error at all before, so I don't know what to tell you. Was working on school projects all night and just ran out of time, so didn't get to fire it up for screenshots, but it looks like you got it to work.
The next thing I'm gonna try is to put it in script form, and I think the solution is to put the busybox parts into a seperate script (android seems to like parsing the scripts all at once, so this borks the busybox commands).
I noticed that its busybox killing the script as well, good luck on compiling one that is compatable i will do wht i can on my end though i dont expect it to be much, thank you for putting this up, one more notch android has over the big apple

REVISED TUTORIAL IN ROOTING 2.3.6 SAMSUNG REPLENISH
warning for experienced adb users!: this was made with noobs in mind. you may learn something (from me! a noob! XD) but anyways, enjoy!
this does not affect anything on the phone except for adding the ability to access root permissions. CWM is not permanent, it disappears after you use it, and nothing on the phone is affected, as far as i know, but i had just factory reset the phone, so use at your own risk...
you may need to know:
root of a drive- drives are designated C:\ or D:\ or whatever letter in windows. Just go to "computer" and double click the first item. That location is the "root" of a drive.
Note: make sure you have at least 400 mb of memory (i know, thats alot, but just in case) on your sd card so you can back up your entire phone! i reccomend doing every optional step!!! It'll save you hassle if you have problems. If you can't make room for some reason, and you still wanna try, you should skip step 8. I don't suggest it though.
1. download "odin.zip" and "su" here: https://www.box.com/shared/620b03e95cc0814fefc8 and unzip to your desktop. if you dont have the android sdk, simply copy the "adb.exe" file from "odin.zip" to the root of your primary drive for later. Just go to "computer" and double click the top icon/item. It should say something about C:/. If you're on Mac, sorry. Idk much about it. As for Linux, I have no clue how you'd even try to do this. I love Linux but, sadly, can't experiment with this in it. WINE has its limits....... And I don't think adb or Odin would work.
2. download the "su" file and put into into "platform-tools" where you installed the android sdk, if you have it, or put onto the root of your primary drive if you havent.
3. start phone while holding "spacebar" and "p". "downloading..." should appear on the screen in yellow text
4. plug into the computer and run "Odin_Multi_Downloader_v4.42.exe"
5. select SPHM580.ops for "OPS" and Replenish-CWM5.tar for "One Package" (they should be the only options) DO NOT CHANGE ANYTHING ELSE!!!!!
6. hit "Start" and DO NOT REMOVE PHONE FROM USB.
7. as the phone reboots, hold "u" until CWM opens and set the phone down. you should close Odin now.
8. use the volume keys to navigate to the backup and restore option and use enter to select backup. wait for it to finish completely and take you back to the the CWM main UI. backing up here creates a pure recovery, untouched by anything. CWM is NOT installed into this recovery. continue with the guide.
9. open the command prompt (type cmd.exe in search or run in the start menu, depending on your version of windows) or use some form of terminal emulator on your operating system of choice. command prompt is preferred due to the fact i know it can get the job done, but do what you will.
10. navigate to the drive your sdk is on and into "platform-tools" or to the folder you put the adb.exe and su files on. the default should be [name of drive]:\Users\[username]\. use the "cd.." command til youre at the root of the drive, and if you installed the sdk, type "cd android-sdk-windows/platform-tools" or just go to the root of the drive and go to the next step if you havent. just be sure adb.exe and su are there.
11. type this in line for line, with enters in between. the blue "~#" in the later lines is the prompt you should have. do not type this. it will be in blue. (clockworkmod should still be open on your phone at this point)
adb shell
~#mount -o remount,rw -t rfs /dev/block/stl12 /system
~#exit
adb push su /system/bin/
adb shell
~#chmod 777 /system/bin/su
~#reboot
DO NOT CLOSE THE COMMAND PROMPT YET FOR THE SAKE OF CONVENIENCE
If you have problems with that, try using CWM to mount "/system". Some friendly people over at androidcentral pointed that out. I personally didn't have that problem, but I'm glad it's fixed.
12. when your phone has rebooted, go back to the open command prompt, which should be where it was before you typed "adb shell"
13. type "adb shell". you will see a prompt of "$." type "su." if you have a prompt of "#" rejoice! you have permanent root! now you can go on the Play Store and find "Superuser" and "Busybox" (they should be free. if you cant find it, get ahold of me and ill try to supply the newest updates) if not, and you have a backup from optional step 2, you should go through til you hit CWM and restore the backup. if not, make one now and reattempt everything aside from downloads and the moving the files around on your computer. Also, someone said something about "chmod 06755 /system/bin/su", so if you might try using that instead of "chmod 777 /system/bin/su". 777 worked for me, but maybe this works better for you.
OPTIONAL FINISH STEP: I dont know how you install CWM permanently, but you should do this so you can make backups of your rom and store them somewhere like on a box.com or mediafire.com account if you decide to mess with something on your phone. (use hjsplit to break it into pieces for uploading and reassemble after download for flashing if its too big). to use a recovery, enter CWM (either the way i have here or if you have permanently installed, just reboot and hold "u") and navigate to "backup and restore," "restore," and select the recovery you wish to use on your sd card (make sure when you take out a backup for storage, you zip up the entire folder with the name that contains the date and time of your backup.) it will overwrite everything on your phone to be exactly like it was when you backed it up.
good luck! have fun!
Note: if you rename the CWM backup file, make sure it DOESN'T HAVE A SPACE or it'll give you something about md5 or something not matching. If it says this, remove any spaces in the name and try again. I had it happen on my xperia play and freaked, thinking it was soft-bricked permanently one time, til I found out about cwm's glitch with that.
Also, I uploaded pretty much everything needed for rooting the phone, with comments pertaining to each file. This includes current (as of July 31, 2012) copies of Superuser.apk, a busybox installer, and the busybox and su binaries, as well the Odin package containing the tools to temp flash CWM.
the odin.zip file and the process of achieving CWM temp-flashing was found at http://forums.androidcentral.com/sa...method-samsung-replenish-android-2-3-6-a.html and credit for that part is given to joshua.worth, although I took it a different path than he did.
Update to above info: to simplify things, I uploaded all relevant files to box so people can get them easier. The su file went missing from xda, most importantly, so I fixed that, and added an updated binary in case someone has trouble with the other one.
contact me at [email protected] if you cant pm me.
Sorry if it takes a while to respond. Life's been kinda crazy for me lately, and I am using my new phone (no service) to do this over wifi.
ahh... well, turns out unrooting cannot be done with a CWM backup... you probably have to find a nandroid or a clean version of kernel with rom. the su file dissapears, although root is still there. ill keep playing with it, i have an idea why root stays although su disappears from the system files. anyways, i will still supply a backup thats pre-rooted for anyone who is willing to have a fresh start on their replenish. it will have superuser.apk preinstalled along with busybox, and everything else will be wiped. this will be a sprint backup, so if anyone has the boost version and is willing to back up with CWM and factory reset, then follow my guide, install busybox and superuser.apk, then back it up again, id be eternally grateful to have a copy
by the way, if anyone has problems with restoring a backup due to "md5" tags or whatever it is, make sure the name of the backup has no spaces. i was freaking out til i found that tip on an obscure forum (well, to me. i dont have a Motorola. lol. just a Sony Ericsson and 2 Samsungs)
update: sorry i havent uploaded the backup. i realized it would give whoever used it the number on this phone and i have to fix that. havent had time to anyways, plus it would only work on a sprint phone. it would convert any boost mobile to sprint, so thats a no-go. sorry...
does this work for the boost mobile replenish that is 2.3.6 if so how long does it take to odin
It should work. And Odin just flashes cwm (really fast) for the duration of the next boot cycle, which it automatically initiates, so hold the recovery button (I think it's u) as it goes into it and you'll have temp root. Make sure it's in download mode before you start. Remember, it cannot be unrooted, so if you value your warranty, plz think twice before doing it. I'm just here to supply the how-to if you decide to, not to say you have to. If you do, enjoy root access!

hmm... i am familiar with the error (ive gotten it with 3 different phones in my attempt to root it, but i have succeeded each time regardless) but are you sure you actually have clockworkmod OPEN on your phone when the error shows up? i cant actually do anything from my end, because i no longer have a computer i can use to test anything, or the replenish i rooted with the method... but i opened the cwm several times before thinking to test the adb and seeing the "~#". i actually restarted the phone and did it again before actually rooting it, seeing if i had rooted it or what, and tho i got the same prompt every time it was booted in cwm, it wouldnt show up if i allowed the phone to boot normally after using odin, i HAD to ACTUALLY boot into the cwm menu, which is completely seperate from the OS itself, although it has access to the system files.
by the way, copy and paste this directly into the command prompt when you get to the step to avoid human error. mount -t rfs -o remount,rw /dev/block/stl9 /system
or, if it wont work, try this mount -o remount,rw -t yaffs2 /dev/block/mtdblock4 /system
sorry bout the babbling XD. anyways, cwm should be circumnavigating the root permissions. hmm.... if you still have problems after that, try skipping to the adb push for the "su" file.
sorry i havent been on top of the thread. ill set up an email notification.
and by the way, something i found very useful on my xperia play when it went into infinite reboot, you can always just restore the system files in the advanced restore option, allowing you to keep all of your app data if, later down the line, your phone needs to be restored. hope this helps. it helped me XD thought id lose all of my messages, but nope. i decided to explore the advanced restore and yay! i got to keep them XD
UPDATE
I don't know if it matters to you anymore, but apparently, some people have trouble with this and fix it by going to the mount menu in CWM and mounting /system
Couple of corrections:
chmod 777 /system/bin/su
should be chmod 06755 /system/bin/su
and then following that command should be
ln -s /system/bin/su /system/xbin/su
and I saw someone say this is unrootable. Thats not correct. Simply running the unroot script would unroot. Doomlord made a nice one.
To use it do the following:
Code:
adb push unroot /data/local/
adb shell chmod 777 /data/local/unroot
adb shell su -c "/data/local/unroot"
adb reboot
[code]
The above will unroot almost any android device.

Unfortunately, Doomlord's method didn't work on it. I tried all manner of one clicks and manual versions and only this got even temporary root. It's a workaround based on forcing the phone to boot into a custom recovery. (I call it custom bc its not an "official" recovery.) And I chose the chmod by looking through many manual ways to root, and that one was popular, and it works. I had full root access afterwards. I tried to unroot afterwards, however, so I could take screenshots and stuff, but the su file would reappear, even after manual deletion or restoring to an unrooted backup. Anyways, point is, this is the only method I could get to work at all, and it does work.
But the "chmod" night help other people, so ill make note of it in the post just in case. Thanks for the info.

Important fix----
If step 11 doesn't work, go to the "mount" menu in cwm and mount /system. Some people on androidcentral were kind enough to mention that this fixed their problem with mounting /system as rewritable

thats because your command is wrong

How? Throughout my own rooting of one of the phones, I had this working perfectly. Every time I hit a snag, I found a way around it and documented it. A few other people had errors show up because the phone itself hadn't mounted the system, but the problem was resolved, and only a couple people had any other problems, and they were unrelated to that. I assure you, every command works properly, as far as I know.
exactly my point. your command to mount system is wrong.
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
lets break it down shall we?
mount - this is teh command
-o remount,rw - this is where you tell it what option you want, in this case remounting as rw.
-t yaffs2 - here you are telling mount that it should expect a yaffs2 formatted device, which is not what the samsung replenish is. the replenish uses RFS (robust file system), the best way i can describe it is like telling your windows computer that your hard drive is fat32 when its actually ntfs.
/dev/block/mtdblock3 - this is where you tell mount what you are looking to mount, the issue here is that the replenish doesnt use MTD blocks, it uses STL's and BML's.
/system here is where you are trying to mount the said device to..
out of 5 parts you did get 3 correct tho. you might wish to modify your guide to reflect the actual mount command, for your device it is the following:
mount -o remount,rw -t rfs /dev/block/stl12 /system
and that will kick out system as r/w

Hmmmm.... Odd..... *shrugs* I had no problem with the command, but I guess other ppl had pickier computers or phones. Hell, Vista's buginess might have worked in my favor that time XD. Thanks for the pointer. I didn't really understand the exact way the replenish was built. I just found a lil guide for making it boot into cwm and found it allowed for me to use that as an exploit to root the device. In fact, I've done the same kind of stuff to root the samsung Intercept, except I made their own software flash a pre-rooted kernel. anyways, I'll update the guide on xda and androidcentral. Thanks!

chances are you had system mounted in cwm without knowing it.
for future knowledge always check the devices fstab for where to mount and filesystem type

as you can see the proper mounts from the files i used to make CWM for the replenish

Eh, maybe. For all I know the first thing I did was mount everything with cwm. I DID do this several months ago. I don't even have the phone anymore. The owner of the phone was gonna give it to me after upgrading, but she sold it, so I kept her 500gb laptop hard drive instead. Popped it out of the external hdd casing and stuck it in a laptop. XD. It now has Linux on it.
Anyways, I've updated the guide to have the right command and note that if it doesn't work to use cwm to mount /system. And how do you find the fstab? Just Google it? Or is it somewhere on the device?
Btw, do you know anything about cwm? It refuses to properly back up my xperia play anymore. The .android_secure folder keeps giving it errors.

its where the recovery is on the device. each device has their own fstab. as for your error sounds like a conflict, either with cwm itself or that folder

It HAS to he cwm, because the folder is regarded as super hidden by the device. The folder itself can be seen, but the contents can ONLY be edited by the rom or a pc, and I haven't touched it with a pc before. It's where your apps go when you move them to the sd card. I've been trying to back my phone up with cwm because I wanted to test the jelly bean alpha release for it. its the xperia play 4g. Stupid backup crashes every time I try and it ends up eating up what room is left in my sdcard.
i followed your guide and have root in shell. however i cant get root permission on any apps, the window doesnt pop up asking me for permission. i also get a toast notification saying superuser access denied for whatever app im trying to open. any ideas?
