[G Tablet General] wd5gnr:
By the light of morning I got back to a full market! But it again broke the web site connection. Is anyone seeing this behavior? Or is it just me?

For the new guys.

1) This appears like it MAY break your connection with the market web site [Update: Wait a few hours and it appears to catch up with you]. It may have other unknown effects. If you are not comfortable with making mods you might wait until more people have reported success or failure with this. For the record I did NOT find this fix (thanks Isira -- see OP of this thread). Just writing up my take on what you need to do. This applies to VEGAn 5.1.1 with supplement. It has been noted that with a stock rom you may need to put "busybox" before commands like cp (which you don't need to use if you have Root Explorer, by the way). If you get this to work (or not) on a different ROM, report it in this thread.

2) That being said, you need a file explorer that will look at / and edit text files, an su utility (comes with your root kit; as far as I know all the custom ROMs are pre rooted) and a command shell/terminal. Or you could spring a few bucks and get Root Explorer which is well worth it and does all of these things. Others have suggested Absolute Root tools which I do not know about. You could also use adb for all of it (which is what I did) but if you know how to do that, you probably don't need me to tell you what to do. We will be changing your build.prop file in the /system directory.

IF YOU ARE NOT USING ROOT EXPLORER GO DOWN TO STEP 3B. IF YOU ARE, GO TO STEP 3A.

3A) Open root explorer. Find /system and press the "Mount R/W" button.

4A) Long press on build.prop and select Copy. Then navigate somewhere like /mnt/sdcard and press the paste button at the bottom of the screen. This is your backup. Please backup.

5A) Go back to /system

6A) Long press on build.prop again. The menu is scrollable. You want Open in Text Editor.

7A) Find the line that says ro.product.device=XXXX (where XXXX is probably Vega). Make it read:

ro.product.device=olympus

Don't change anything else.

8A) Save the file by pressing the menu key and selecting Save & Exit.

9A) Scroll to the top of the /system directory and press the Mount R/O button.

10A) Reboot your tablet. Wait for things to settle down on restart. Open Market. Look for Saumari 2. Look for LauncherPro, Opera Mobile, etc. It will all be there.

If you don't have root explorer:

3B) Open the terminal. At the prompt, enter (spaces and lower case matter):

su

mount -o remount,rw /system /system

HINT: If you think you will do this a lot grab Script Manager off of the market. You can put the mount line in a script, tell it to execute as root (which is the same as su) and then you can run the script when you want to make changes.

4B) Start your file manager and find the /system directory. Your file manager probably starts in /sdcard or /mnt/sdcard. You'll need to go "up" a directory or two to root and then back down. Either way, when you find it, make a backup copy of build.prop somewhere you can write to. Seriously. Do not skip this step. Make the copy.

5B) Edit build.prop. You are looking for a line that sys ro.product.device=XXXX (probably Vega; I don't know about other ROMs and if this works for other ROMs but for VEGAn 5.1.1 its Vega). Carefully replace whatever you have as XXXX to olympus. So the line should read:

ro.product.device=olympus

Note: Some of us had other changes to build.prop. Not clear if these had any effect or not.

6B) Save your changes. If your file explorer is not root, you probably need to save the file to where you can write (your sdcard for example) and the copy from a terminal, such as:

su

cp /mnt/sdcard/new-buildprop.txt /system/build.prop

or

su

busybox cp /mnt/sdcard/new-buildprop.txt /system/build.prop

7B) Open your terminal and enter:

su

mount -o remount,ro /system /system

Remember spaces and case count! Also if you are in the same terminal window as before you don't have to keep entering su since you stay root.

NOTES FOR BOTH SETS OF INSTRUCTIONS

I did the original market fix after saving the file, but some people say it is not necessary. But at least a few people have said they don't see much or anything in market until the redo the fix (the one where you delete the market cache and the google services framework data and reboot).

Things that appear to work:

1) Installing free programs

2) Updating existing programs

3) Amazon market web site oddly enough

4) The official market Web site AFTER WAITING SEVERAL HOURS

5) Buying an app off the build in application

Some of us had other changes to build.prop but I don't think any of them were significant. If you have trouble you might apply it (shouldn't hurt). Also, if your "my apps" only shows your paid apps (or nothing if you have no paid apps), try downloading anything off the market and that will usually restore it. There is also an update local cache key that might do the trick, but loading some freebie off the market is easier. Also check to make sure gtalk is logged in. You can try forcing a resync on your Google accounts (in the main menu under Accounts).

Hope that helps someone. Its early so I probably made mistakes and will edit any that are found.
