I tried to install the stock 3389 (i believe) on launcher pro. The result is I have the stock version (tapNtap) and Launcher pro.
The problem is I could not enter into cwm mode. I see the two black and white lines and then goes on to see the GTablet logo.
What should I do to enter the cwm mode again?
If I understand, you flashed 3389 and can no longer use recovery keys to start CWM.
1) put 'CWM' as 'update.zip' into '/sdcard' or '/sdcard2' folder
2) put correct 'command' file into '/recovery' folders *
3) shut down
4) restart recovery (hold 'power' and 'Vol+' till you see recovery booting)
5) wait while CWM is installed
6) reboot
* line in 'command' file must point to correct location
Thanks.
Yes your understanding is correct, tried to flash 3389 over Tnt 4.2.2 and ended up loosing CWM.
Thanks, it did work and now I do have the Stock version and Tnt 4.2.2 kind of dual boot.

When I got my G tablet yesterday and rooted/flashed to 2.2 Lite, I did it using my G1's SD, but since then I backed up my SD to what I had it on my G1. My question is, can the G tablet naturally boot from an SD card(micro) as long as its named update.zip? I mean so I can do the flash again or is it perma bricked? If it is perma bricked, should I return it to store and start all over with a dedicated SD card?
Thanks!

Necro,
This tablet is 99% unbrickable (I would say 100% because I haven't head of one bricked yet but nothing is impossible). you just need to boot into APX mode and reflash stock firmware
how to get into APX mode can be found here
http://wiki.tegratab.com/index.php/Nvflash_FAQ
you are going to need to download the complete NVflash restore file
which can be found here: http://forum.tegratab.com/viewtopic.php?f=13&t=18

The download link for the SDK is broken or old. Is there another place I can download it. Stupid google keeps bringing me the PDFs for Nvidia. Nevermind about the SDK, found it on their site. What about the original ROM/IMG? That link is also broken.
Is there a better guide. I'm getting a headache from all the files the SDK dumped onto my computer. Can someone show me a noob proof version of how to do this?
I only undertand the APX mode on the G Tablet. Other than that I cannot get windows to recognize the device even after installing the SDK. Where are the drivers for the APX?
There are instructions on the main post for TNT-Lite for what to do if you get into the boot loop. I ended up having to get to the step where I repartitioned the internal flash and re imaged.
You can avoid the SDK and driver issues and only use the computer to put some files on the SD card:
Easiest way to fix for me was (I had same issue problem with 2.0):
1. Download "Clockwork .8" (links at XDA)
2. Unzip the recovery file and update.zip to root of a micro sd
3. Change the recovery folder's command file to "microsd2" & save it
4. Put the card in the Gtablet
6. Interrupt the boot loop by pressing power and volume up at same time
7. Clockwork should install
8. Power down and restart the G tablet
9. Download TnT Lite 2.20
10. Repeat 2 and 3, but this time extract the update.zip file from TnT 2.20 and copy over the update.zip already in the root directory. YOU WILL NOT NEED A RECOVERY FILE FOR THIS METHOD.
11. Delete the recovery file in the root directory
12. Power down
13. Restart by pressing power and volume up
14. Should be in Clockwork
15. You want to clear both cache and data (two options on main screen)
16. After clearing both, choose install update.zip.
17. The next screen will show the update.zip. Go to its row and choose it by pressing home button
You should auto reboot and be set. You can then install the Folio Flash apk and install Titanium so you can do the market fix.
This is process is what saved me, at least.

Did not work... I might go and return it tomorrow. I even tried flashing to original firmware and nothing.
I got stuck in an unrecoverable boot loop as well. I tried to install TNT Lite 2.2, got a boot loop.
Tried to install TNT Lite 2.2, 2.2.1, 2.3 from microsd (yes changed the line to SDCARD2), always got the giant exclamation mark.
Tried to install the vanilla restore and stock TNT from here http://forum.xda-developers.com/showpost.php?p=9439414&postcount=7 still exclamation mark.
Tried to install Clockwork Mod, still exclamation mark.
EDIT: Finally got out of my bootloop by flashing the ViewSonic G-Tablet Restore file from DroidPirate
http://www.droidpirate.com/download/click.php?id=1777
http://droidpirate.com/category/ablets/viewsonic-gtablet/
Its the only one that worked.
I can't get into recovery. Long story short I went from TnT to ????. I was able to figure out my back back but now I get FCs all the time. I read somewhere that I need to wipe my data but I can't get into recovery.
This is what I have done so far:
1. Rooted again with Z4Root (it was gone after putting back the TnT)
2. I followed this thread to get Clockwork again (http://forum.xda-developers.com/showthread.php?t=865245). After unzipping the file I made sure it was in the right place.
3. I reinstalled ROM Manager - I still can access the app but nothing happens when I select anything from the menu (i.e. Reboot into Recovery or Restore Backup)
4. Because ROM Manager is not working I did the power and Volume + and I see the message: Detect a recovery key pressed but I get all the way up and not into the recovery menu.
I have fixed the market and everything but I get FCs for almost every app that I try to use.

Update: the command file was setup to sdcard2
Hello, newb here (for now)
My nephew rooted my Best Buy Nexus S (AT&T) and installed Cyanogen 7, it works great, but I think I have a defective screen and I need to exchange it at BestBuy. (Screen Flickers/flashes at times)
The kid is gone back home and I need to get back to stock. Here's where I am right now:
- I launch Rom Manager (4.3.3.0) go to "Download ROM" and scroll down to "stock images" and download Nexus S 2.3.3, it downloads.
- Then the "Rom Pre-Installation" screen comes up and I choose all three options (backup, Wipe data/cache, Wipe Dalvik Cache)
- I press "OK" to reboot and get the Google Screen with the lock and it just stays there (I waited about 10 minutes)
- I pulled the battery, power on with VOL up and get to "Fastboot mode" (I think... screen with choices and android character?)
Anyhow, I've tried every option here and i cannot get it to load anything to replace the Cyanogen 7 Mod.
Maybe I need a stock AT&T Image? The one from Rom Manager is wrong?
With all of that said, I'm using a MAC.
Any pointers or suggestions?
Thanks!
I think my issue is that it will not go into recovery mode. When I choose recovery, ut goes to the google screen with the lock at the bottom and never gets past that.
For whatever reason, using ROM Manager to flash a recovery onto the Nexus S makes it disappear. I did this myself and it made the recovery image vanish.
So use fastboot to re-flash the recovery image.
Download this file: http://download.clockworkmod.com/recoveries/recovery-clockwork-4.0.0.2-crespo.img
Rename it to "recovery.img" and copy it into the "platform-tools" folder.
Plug the phone into your PC, and boot it into fastboot. Open a command prompt and move to the platform-tools folder, and type "fastboot flash recovery recovery.img."
When it's done, reboot fastboot and when fastboot comes back up, scroll down to recovery and select it. It should boot into ClockworkMod Recovery.
Thanks for the reply!

Access your phone's memory card from Mac and enter sdcard/ directory. sdcard/ is your internal storage where you should put your ROM, if you decide to flash ROM or any .zip file from CWM's recovery.
I have just updated my nexus s to the latest 4.0.4 update..now i want to bring back root access .. as we all know were going to loose root access if we updated. anyway i previously used this method http://nexusshacks.com/nexus-s-root/how-to-root-nexus-s-or-nexus-s-4g-on-ics-or-gingerbread/ now im wondering if this also applies to 4.0.4 update and what is the best recovery to flash on this update?
The only thing i did was upgrade to 4.04, dont reboot but flash superuser, all clear, root is back.
[Q](solved) how do i bring back root on my i9023 ics 4.0.4

hmn... what i did was
i went to adb
open cmd
flashed recovery3101.img
after that i installed superuser using CWM recovery . if your using the stock recovery it will only show an error msg. didnt wipe anything ... all is ok and well hehehe cheers!
I have issue with CWM and Root. I've follow the guide here.
I manage to successfully do up to step 4 without error. After that, when I reboot the device, it have a message "android installing update". I installed titanium backup and it says no root access. Superuser is available. When I tried to update on Play "Update for Superuser could not be downloaded due to an error (941)"
I tried to go back to recovery, it is the stock recovery instead of CWM. I've updated my 9023 from 4.0.3 (stock non root) to 4.0.4 using CWM. I've installed superuser using CWM as well. But when I reboot the device, it went back to stock recovery. I've tried fastboot CWM, turn off, then turn back on to go recovery, it is using CWM. But when I reboot, and try to go back to recovery, it goes to the stock recovery.
Appreciate some help. Hope my explanation is clear.
Will
First try flashing the latest Superuser than reboot, then open rootexplorer
Rename "/system/etc/install-recovery.sh" to "/system/etc/install-recovery.sh.bak".
All Stock ROMs replace the recovery on each Boot if it isn't the stock one. Renaming this script stops that. After you do this, flash CWM one more time and it'll stick.
Thanks to harbb who helped me with the same isseu
not sure if this is legit... I found a few sites with the same tutorial but different backup apps same file download though... can anyone varify?
filename: Superuser-3.0.7-efghi-signed, from a mediafire download (/?57iroxlzh8bb5qi)
from tutorial: Root Nexus S with Android 4.0.4 ICS IMM76 Firmware, from androidlot.com
(sorry can't post link)
it just said to do a recovery from bootloader, no other tampering needed... was thinking of using it if it worked as I just did the Nexus S 19023 OTA update 2.3.6 - 4.0.4 found on this forum but wanted to root to use voodoo sound... first timer and dont want to mess around with roms or cwm... figure no harm rooting as Nexus S probably won't get anymore official updates
Signature verification failed
well i have tried to install the superuser from recovery (apply update from SDcard) but every time i try to install the zip file it gives me signature verification error .

That means your not in CWM Recovery. You have to follow the guide and use fastboot to flash a custom recover. Thats why we use a custom recovery, to bypass the signiture check
so wats da final result?
in ics 4.04 how to flash cwm and root and install vodoo?
ended up using m.sabra's one click root and flash cwm tool (/showthread.php?t=1544940) worked a charm, downloaded voodoo sound plus so i didnt have to flash new kernel, putting music back on phone now (had to unlock bootloader) to see how it sounds
also used appbackup&restore, copied backup folder from sd to computer, used the root tool, redownloded appbackup&restore, copied folder back from computer to phone, allowed install from non market, reinstalled all apps
now have superuser and cwm and all my apps back
Hope this may help. it's the way a did it on my Nexus S
Download fastboot for Windows or Mac.
Make sure you have the Android SDK installed.
Download ClockworkMod Recovery.
Download the Rooted Su Binary for 4.0.4
Make sure you have the necessary drivers installed for your device
Put your device into Bootloader Mode (turn your device off, then hold Volume Up + Power).
Once in Bootloader Mode, type the following into your Command Window
fastboot oem unlock
You should now see a couple of lines go through on your Window.
Then Type the following:
fastboot flash recovery recovery-clockwork-5.0.2.0-crespo.img
Provided this went correctly (it should), you now want to cycle down to “Recovery” on your device using the Volume buttons and press Power to confirm. This should boot you into ClockworkMod.
Select Recovery again, navigate to “Mounts & Storage” and then to “Mount USB Storage”. Once this has been done, your SD Card should appear on your PC.
Copy the Rooted Su Binary you have downloaded to your SD Card, and then Unmount USB Storage on your device.
Navigate back to the main menu of ClockworkMod and select “Install zip from sdcard”, then “Choose zip from sdcard” and select the package you just copied across, and then confirm the installation. This should install the package and root your device.
Hey guys sorry i was on vacation, thats why it took me so long time to come back, anyways... here is the link of the step by step procedure on rooting your nexus s, this is what i followed, http://nexusshacks.com/nexus-s-hacks/how-to-root-nexus-s-or-nexus-s-4g-new/
but what i did was ;
1. after updating i lost root
2. open adb tool
3. flash new recovery3101.img ( this is to replace default recovery from the stock ics 4.0.4)
4.then installed superuser from the new recovery that i installed ( CWM)
i wont go through all the details since , the link already explained that there....so cheers and hope this works for you , all the needed files is in the link also.

Hey whiz kids,
I upgraded to a new NIghtly cm-10.1 for my tf300t through the custom roms app. Problem is I didn't have a upgraded bootloader, it could be as old as honeycomb I don't know. Whats happening now is a the first Asus screen loads up and its just frozen there permanently until the device dies. I can get into RCK and Fastboot. Apparently I don't have a backup either. What are my options?

Whoops, sneezed and clicked the Thanks button. Oh well... you have my thanks.
Load a stock ROM on you microSD (available on ASUS' support website), and flash it from recovery. This should update your bootloader in addition to flashing a bootable ROM. Then, reflash CM's nightly.
It might be better to ask in the 300T section in case there's any slight idiosyncrasy's that differ from the TF700T.
Marty is right though you should be able to flash back to ICS and start over with an unlocked bootloader.
Appreciate the comments back..thanks. I tried the suggested idea, however, the microsd card inserted on the side of the tablet doesnt have an option in recovery to open up and view the files. The only option I have is to look through the internal usb storage drive, since I cant connect the tab to my computer in an way I tried so far, I cant get an old rom into the internal drive.?? Its just frozen on the asus bootloader screen and wont even turn off lol.

Hold down the power button long enough will enventually turn off the device. Make sure it off first then boot into recovery and see if you can access your sdcard. If not working hookup usb cable between pc and your device, boot into recovery (home page), then open adb on your pc and make sure the rom file is in the same directory of your adb command, on your pc run this command to copy file to your internal memory:
adb push c:\folder_where_adb_and rom_zipfile\rom.zip /sdcard
OK..I sent the file using adb push it took like 90secs and it confirmed the asus jellybean firmware (10.4.2.16) file at 100mb. Only problem is is that its not showing up in the sdcard. There are just a bunch of folders with no new .zip files.?? I dont understand why the file wouldn't show up after it says it sent it.
Which custom recovery are you using? Sounds like you need to re-do it from a PC when in fastboot mode ( choose USB icon in boot loader ). Make sure you use the latest TWRP or CWM as they both read the card fine.

I copied it here because I wanted to point out the rename step that's needed if you're on stock recovery somehow. I too am curious as to what recovery is active on your system...
*** Factory Restore after a softbrick/Downgrade from Jelly Bean to ICS/Clean Factory Restore ***
When You Need This?
* if you get stuck on Asus boot screen (the one with the spinning wheel)
* If you don't like JB and you want ICS back
* if you want to get back to a clean stock firmware
Note: You need to have a working recovery (stock or custom) in order to use this method.
========= Recover /Downgrade from Jelly Bean to ICS/Clean Factory Restore with stock recovery =========
1) Download the latest firmware from Asus site (based os your SKU,eg. ww 9.4.5.26 * to downgrade from Jelly Bean you need the 9.4.5.30 firmware)
2) Extract the .zip file somewere on your desktop (the result will be another .zip file,use it for step 3)
3) Rename the extracted archive to "EP201_768_SDUPDATE.ZIP" (without the " ") and upload it to a MicroSD card
4) Insert the MicroSD card in your tablet and use this button combination to Power ON and go to recovery --> Start the tablet by pressing Volume Down and POWER togheter for 5 seconds ,a message will inform you that you have 5 seconds to enter the recovery,press Volume UP before the 5 seconds expire.
At this point the device will go in recovery and should start updating your firmware .
Note: Keep in mind that Windows doesn't show the known file extensions so most users don't have to put the .ZIP extension in the filename.

2) Extract the .zip file somewere on your desktop
3)Rename the file to something like "recover.zip" uploade it to the root of your MicroSD card
