I try to keep the first post in this thread fairly up to date with instructions. If you have a stock device, everything you need to know is there to flash to TnT Lite. You don't need clockworkmod and I would recommend that you stay away from clockworkmod until you feel comfortable with it.

And wipe your user data after flashing. It's always a good idea.

The only other thing you'd probably want is a backout plan to stock, and there's another thread here with the ZIPs for that.

Anyone having problems with artifacts? I just updated to 2.2 from 2.0.4. I was getting constant force closes for I believe "acore" process, so I did a factory wipe/reset.

The artifacts show up clear on the standard calendar app, where some strange lines are through the top days on the monthly view. Is there a simple fix to this, or is this related to the newer drivers?

Edit: I see the artifacts are normal, nevermind.
[G Tablet General] kevin stone:
So is this the part i should use?

I am assuming that I need to do this thru my pc or do I load a image on the cf card like I do in win Ce?

Instructions for those with standard recovery:

- Extract the RAR to the root of your internal memory. So, for example, if your device is mounted on your Windows F drive, you need to extract the RAR so that you have an F:\update.zip file and an F:\recovery folder. Then, unmount the drive cleanly.

- Power off the device, then begin the flash process by holding the power switch and volume up switch for several seconds. You should see a recovery screen and it will take 1-2 minutes to complete.

- After the update is complete, the system will reboot.

- You will see the standard Google registration screen, on first boot. You can skip the Google registration process and try later, when you have WiFi running.

Note: these instructions are for the internal memory. If you have no access to that (ie stuck in a boot loop), you can add the files to a microSD card and that will work. However, you need to make one edit to the \recovery\command file, which is a text file. Edit it in notepad and change "SDCARD" to "SDCARD2" and resave it. But, make sure that Windows doesn't add a .TXT extension - it HAS to be called "command".

There are some common apps that don't show up in the market for the g-tablet even though it seems there are billions being populated.
[G Tablet General] probenet:
Try install Clockworkmod v.08, the download link is in the first page.

In CW Recovery:

-Wipe Data Factory Reset

-Wipe Cache

-Under "Partitions Menu" Format All Storage

Reload TnT-Lite 2.20

This have fixed my acore crashes
[G Tablet General] grimsocks:
Well third time was the charm for me, I got my newest one today and just put 2.2.0 on it, THANKS you guys for doing an awesome job here on this. Its a cool tool with some interesting potential.
[G Tablet General] NewbTrader:
Hardware decoding for Rockplayer now works.

Well, I upgraded from 2.0.4 to 2.2, and I noticed that now Hardware decoding works in rockplayer, where as before only software decoding would work. It seems the newer nvidia drivers included some new functionality that didn't exist in the older ones. The default "movies" and "Movie player" seemed to have hardware decoding working in 2.0.4 fwiw, but now rockplayer hardware decoding works as well. Interesting..

Oh ya, the hardware decoding results in higher framerates. Software decoding dips to as low as 13 fps in the h264 movie I encoded, but with hardware it seems to hold steady (it doesn't display the fps w/ hardware decoding, but visually I don't see a big drop off during high motion scenes).
[G Tablet General] digitalman2112:
Install the ADW.Launcher from the market, then you get the ability to change its settings. I had to work to find it in the market, may be easier to sideload if you have another device. I eventually found a web link that took me to it in the market, then immediately made a backup in case I needed it later :)
[G Tablet General] maxman0077:
awesome job!!!

I'm cranking at 2477 according to quadrant. Thanks Roebeet.
[G Tablet General] prerunnerseth:
You wont be able to do back ups or clockwork til you load atleast one versioon of tnt lite. Its real simple. Open the zip. Mount the SD card in stock Rom. Copy update.zip and the recovery folder to your SD card. Shut down the tab. Hold volume up and power up the device. It will auto load tnt lite. Then side load titanium backup and do market fix.
[G Tablet General] Reginhild:
Maybe slightly different wording will help......

You've got it...basically uncompress the stuff in the .rar file that you download from roebeet's link.

You will have a recovery folder with a command file in it. You will also have a Zip file (leave as a zip).

Copy the zip file and the folder with the command file to the topmost level of the internal storage in the g tablet. You need to connect to the computer with a USB cable to copy from a home computer.

Disconnect the USB cable and power down the g tablet.

Restart the g tablet by holding down burn the volume up button and the power button at the same time. The load should happen.

....if this does not work then try copying those files to a micro SD card instead. Use text editor to change the command file first by adding a number 2 after "sdcard". This will make the system point to the microsd instead of the internal memory. Put the microsd in the g tablet (while powered off - not while just asleep). Start up by holding down the volume up and power buttons at the same time. The load should happen.
[G Tablet General] prerunnerseth:
Just as a warning, shutting down with quick boot has screwed up my tab twice. Thank God for nandroid backups.
[G Tablet General] roebeet:
I added extra instructions in my first post, if you need to re-image. You can use a microSD card, since you can't get into the internal memory to setup the ZIP / recovery folders. It's the same instructions, except that you have to make one edit to the /recovery/command text file.

Worst case, you can use clockworkmod (also in my first post, and again with a microSD card) to flash recovery. The reason why is that this could be a system problem, but it would also be a user data problem -- and the only way to flash user data in a situation like this is to use clockworkmod.

Imo, you should always wipe your user data after an upgrade like this - it's really the best way to keep your system stable. In stock/ TnT, you can do that in settings -- security -- factory reset, once you are back up and running.

Roebeet your work kicks ass, I still have time before I buy a birthday present for my son...leaning toward the netbook but your work might sway me.
[G Tablet General] roebeet:
My son (11) is actually getting a netbook for Xmas, not a tablet. He likes Angry Birds, but he has to have RoBlox and that's Windows only. :)

Radio Shack has one for $180, on Black Friday. And Worst Buy will have one for $150 but that store is nuts.
[G Tablet General] akodoreign:
$228 at sams club (LED screen, looks pretty spectacular).
[G Tablet General] roebeet:
I have my backup, already - Target had an Acer netbok for $180 on Sunday (I got one). Unless I manage to snag the Worst Buy one for $150, it's the one I'll give him.

The ACER is Windows XP, but I have a TechNet subscription so it's just going to get wiped anyway. Windows 7 FTW!

LED screen sounds pretty sweet, though. Must be nice as a comics reader. Uh oh..... :)

[G Tablet General] Linuxslate:
Not so happy any more.

Exactly the same problem as how lowformat.

Worked for a few hours, and now I'm into rebbot loops.

Its effectively slagged until I can get home and try to recover via an SD card.
[G Tablet General] akodoreign:
I had similar issue with 1.3 from last night going into this morning. went to 2.0 and it worked again, Seems that it does not like to wake up.
[G Tablet General] photonmedia:
Flashed about an hour ago. So far, so good.

gotz ma angry birdz agn! lol

Yeah but anyway, great work Roebeet! You and Rothnic are pretty much the only reason this tablet is worth a damn. Would be great to see WPA-Enterprise support in TnT lite, but for now, I'll manage. ;-)

Oh and big ups to whoever figured out that Titanium Backup Market hack/fix!
[G Tablet General] xfernand:
No luck with your suggestion. Check and uncheck multiple times. neither Exchange or Gmail. They both show the circle icon indicating data synch but once they go away, no contacts.

Calendar worked well from the very beginning...
[G Tablet General] roebeet:
I know that original stock had this issue (for me). Reboot loops and also the "sleep of death" where it would refuse to come back on and you had to wait for the battery to die.

I've been pretty stable since I used nvflash and I still think that there's some imaging problem with some of these devices. That's my guess.

If anyone finds a better Contacts apk that works, I'll add a supplement. Unfortunately, for some of the canned apps I basically just checked to make sure they ran and not much more.

Don't forget bekit and the other devs that worked on clockworkmod and nvflash! I am eternally grateful to them!
[G Tablet General] xfernand:
Music Player

Music not picking up files from the external SD card. Maybe there is a setting we can tweak. It did on the version on CM6...
[G Tablet General] roebeet:
That's a known issue on the stock firmware. It's because the ext card is /sdcard2 and a lot of apps can't read that. That includes the music player.

I know the zPad firmware mounts it under /sdcard so it works better on the zPad firmare as well.
[G Tablet General] Linuxslate:
BTW, before my G-tablet went into reboot fits, I was able to fix the market simply by doing:

Settings >> System Applications >> Google Services Frameworks >> Force Stop

Settings >> System Applications >> Google Services Frameworks >> Delete Stored Data

Then the following in some order, but not sure of that order:

Wipe to factory settings ---- Market Errors --- Reboot --- Wait --- Working market (Did not try paid apps)

Also, just before the reboot fits, I was trying to create an M$ Exchange Mail setting in the eMail App. I started getting constant FC in that app, and decided to reboot. That resulted in the Birds >> G-tablet >> Reboot loop.
[G Tablet General] bmasephol:
Finally was able to download and flash today. I love that Flash works now in the browser with the sideloading of the Flash apk. The settings -> display crashes for me when I click on it, anybody else have the problem?

Yesterday on zPad I played around trying to get swype or slideit to work on the tablet but swype kept crashing and slideit takes up half the screen with it's keyboard. Anybody else try these?
[G Tablet General] insight3fl:
I will be trying the new system tonight...perhaps it had somthing to do with replacing the old one on 1.02 rather han it being built in as on 2.00 I will let you know my results.

just curious, but i had my exchange email set up and syncing...then I added gmail to the email program after that.
[G Tablet General] New2Android:
blank screen

Hey Roebeet,

Great job with the TnT 2.0

I updated fine with your above version and was able to get booted up. then did factory restore and booted up again to remove old data. I was on the latest viewsonic updated released yesterday.

However when i was trying the market fix and was installing the titanium backup suddenly the screen went blank and now wont respond to any touch or even power button.

What should i do? Should i wait for the battery to drain out completely?

Please advice.

Also as and when the tablet starts up again what should i be doing to ensure that i get market and a stable tablet working?

Thanks in advance
[G Tablet General] Hannigan174:
My long press buttons no longer work in 2.0, I am not sure if this is intentional, a side effect, or something I did. If anyone else has this issue please let me know, and a possible fix for the long-press home button function.

Also, does anyone know how to edit the launcher, since we can't access the correct settings?
[G Tablet General] Linuxslate:
re-flashed this FW, but I am still stuck in a re-boot loop since, appearently the problem is still there.

I need to wipe.

How can I do this?

Cyanogen?

put something in /recovery/command?

When I boot holding Vol (-) I get a black screen -- Is that fastboot?

Will try above later this evening.
[G Tablet General] Crimton:
is there any way to get another video player on here? like the one from zpad. i hate the normal gallery.
[G Tablet General] hymis:
Hi Guys, i got 2.0 to install just fine but I cant get 2.2 for the life of me. Im using clockwork to install the new rom but I dont think its working. How do I find out what rom im running? Thanks guys!! You should have a donate button somewhere. Im down.
[G Tablet General] Darkness863:
Tried this method but it didnt work very well for me, slowed down my TNT Lite. Kinda wondering if i could change the shortcuts on the stock launcher. Anyone else got any good ideas?
[G Tablet General] Darkness863:
Wipe date and cache, then extract the contents of the zip (2 folders, one named update.zip and one named recovery) into the root of the SD card. From the main clockwork mod menu, select apply sdcard:update.zip

Don't forget to delete any old update.zip files you might have prior to doing this as well as the recovery folders that accompany them, also, backup your current rom in clockwork mod.
[G Tablet General] gotwillk:
question: in the first steps to flashing this rom it says to have a microsd card for use. does that mean i need a spare microsd? doesn't the tablet already come with a microsd? the 16gb internal memory is the microsd right? do i need a microsd? can i use a sd instead?

sorry for the noob questions but i just ordered a tablet and waiting for it to arrive so i'm preparing myself so i'll be ready to flash.
[G Tablet General] GideonX:
Not necessarily need, but have just in case you mess something up.

It does not come with a microsd. The internal memory is just that, internal. You can't use a SD, it only supports microsd.

If you follow the first post, you seriously can't mess this up.
[G Tablet General] gotwillk:
oh the specs said it supports SD card, but not microsd. weird. what class of microsd can the tablet take? will 6 work or is that overkill?
[G Tablet General] GideonX:
It'll work, overkill.
[G Tablet General] hhsq78a:
Work outstanding, thank u!
[G Tablet General] dan1431:
roebeet, excellent job!!!!

One quick question, is it possible to update the Android core to FRG83 or FRG83B? These two versions of Froyo seem far more stable on my Nexus 1.

No biggie if it is not possible, I really appreciate your work and am very appreciative for all that you have done for the community.

Thanks,

Dan
[G Tablet General] mdwalker@yahoo.com:
Probably not yet

From what I've gathered...

TNT lite is based on the stock Tap n Tap build, which has some custom software and quirks. I believe you can't replace the core stuff without breaking the stability of this platform.

However, the Vega based build is aiming for more stock Android where this might be possible, and that also might be true of the zpad and/or CyanogenMod builds.
[G Tablet General] tcrews:
Just and FYI, those aren't version of android, those are the number of builds done for the Nexus 1. The Android those are built off of is 2.2.1 but they've done 83B builds until they got a "release". Proprietary drivers, etc.. could have changed between builds or they added things to the framework or kernel or whatever that they felt was significant enough to increase the "build number".

Build numbers are device specific and aren't related to Android versions (2.1, 2.2, etc...)
[G Tablet General] TheTruth:
technically we can just nvflash about anything, so long as the kernel, framework and needed drivers are there for our system... if you are feeling up to it you could flash the latest build found on the nv tegra developers forum and things should work just fine.

there is also a tutorial there on how to get ubuntu running but that is not for the faint of heart...

I've said this before, but there is quite a bit of "evidence" that the gtab and other malata derivatives are nothing more than a developer board put in a pretty package...
[G Tablet General] cjbailey75:
Did anyone work out the portable hd not working fix?
[G Tablet General] flipper9:
Some strange things...

1. I'm starting to get random Google service framework FCs.

2. The right side of my touch screen seems to now require a firmer touch to register and seems to work intermittently when tapping.

I'm using the latest TnT Lite 2.2.0
[G Tablet General] Arcyne:
Can't seem to download the new 2.2.0 from the hosting shares.

Anyone else having the issue? First line seems to no-op for me. (Tried on multiple computers and my g-tablet.) Second link says the file is temporarily unavailable.

Normally I'd just wait a day or so and these items resolve themselves, but unfortunately my tablet is in a state where I should update now. (Somehow I triggered a firmware update my gtablet was in its case and when I booted it up in the airport I was at the initial set you machine up wizard.) :-(

Since I will need to reset the device I might as well perform the upgrade now.

Thanks in advance.
[G Tablet General] roebeet:
2nd link is down for me, but the first one is working. YMMV.

You might need a data wipe (if you hadn't done that already). Are you getting the UID "I'm feeeling lucky" errors?

As for the firmer touch, not sure about that one.

You can do me and the other modders here a big favor -- called Viewsonic and ask for the source to be released. Seriously. That's the one thing everyone here can do that would be a major help. Call them and complain.

I call them every week, but I'm just one person. If we can get the source (specifically the drivers for the touchscreen and whatever else is in the kernel), then we could make our own builds. Right now it's just a lot of guesswork and trial and error.
[G Tablet General] cherokee2217:
Quick noob question. Did the 2.2.0 upgrade from stock and all looks well. But per roebeet's suggestion to wipe data and cache as the next step before proceeding, I can't figure out how to do that. I don't see "firmware" under Settings to do a "Factory Data Reset". Please advise.
[G Tablet General] roebeet:
Sorry, I meant "Security", not "Firmware". Brain fart.
[G Tablet General] Turbo4V:
No fc's here, but I'm also seeing the issue with the right side of the screen, rolling back to 2.00 seems to fix it, might be something to do with the performance pack?

Justin
[G Tablet General] cherokee2217:
Thanks reobeet. That worked!
[G Tablet General] roebeet:
That's definitely a possibility - the PP affects a lot of things. I'll have to test that out a bit more, this weekend (taking a break from the Vega build testing, anyway).
[G Tablet General] rushless:
64gb thumbdrives and 500gb WD USB drive work for me. Both in FAT32.
[G Tablet General] flipper9:
I did a full wipe, repartition, and reformat of all partitions including sdcard then reinstalled. Seems to be fine for now and was fine beforefor the first 24hrs or so. I also didn't restore with titanium backup this time so opted to manually reinstall everything I use from the market. I'll keep testing.

As for the touchscreen it could be hardware or software related, dunno.
[G Tablet General] rushless:
Roebeet, perhaps a little bad news in regards to 2.20, since there still appears to be something wrong with the new rom, 2.20.

Angry Birds and other apps are vanishing, just like they did with 2.03. Plugging in USB drives appear to accelerate apps vanishing. The same apps that vanished with 2.03 are now vanishing with 2.20. At least they appear again with a reboot, but USB drives cause them to vanish and you have to reboot to use the apps.

Seems that after using a USB drive, some apps vanish instantly and some like Angry Birds are there, but when you touch their icon, they force close and vanish too.

Already aware of this?
[G Tablet General] Arcyne:
I was able to get the file to download and install. I have to say that the performance difference is definitely astounding. Definitely worth the accidental reset!
[G Tablet General] cutterjohn:
Did a stock TnT -> TnTL 2.0 -> TnTL 2.0.2 -> TnTL 2.1.1(had to wipe) -> TnTL 2.2.0 (over the course of c. 1.5w or so...)

Didn't wipe or fix perms and had no problem booting it twice(so far) and web browsing for c. 2h. Had to re-install flash of course, and haven't really tried to download anything from market yet either...
[G Tablet General] jtbnet:
I did NVflash back to Stock first to test stock->2.2.0 as figured unlike us that have tried each version... newbies would be stock... so stock, add clockworks, then use zip on /sdcard to flash direct to 2.2.0 works like a champ!! I did use clockworks to flush cache after installing 2.2.0 so not to get the FC's on first boots after changing versions and not a single FC in over a day of use...
[G Tablet General] envy731731:
noob question.. I downloaded the rar file extracted to the root of the internal sd and shut off the device then rebooted holding down the Up vol and power key and i get the msg at the top of the screen saying its loding the recovery but then just boots like normal. I have also tried the same process with my external sd card and same results.... Am I doing something incorrect???
[G Tablet General] Talk2Rider:
I experienced a problem yesterday with 2.2.0. Prior to getting FC on all the GAPPS, I had been syncing with media player, deleting files off the internal memory via usb, and tinkering with bluetooth trying to get it to pair with my PC (so I was in Settings alot). After the tablet resumed from sleep, I began getting FC related to the GAPPS. Reboots did not solve the problem, nor did clearing the cache from clockworkmod. I did a restore from the previous day's backup and all was well - in fact I was up until 2:30am playing Robo Defense - another very addicting game.
[G Tablet General] roebeet:
I definitely had some apps vanish over the last week, but I was working on these supplements so fast that I didn't have time to really figure if it was just me reflashing over and over again.

Angry Birds was an app I noticed disappearing at least once.

I'll test the USB drive theory - I don't really use a thumb drive all that much but I'll do that more. Are you noticing it after anything specific, like running a video off a flash drive?
[G Tablet General] kevin stone:
2.0??

As a noob would 2.0 be a better starting place than 2.2?

I need flash and the market and exchange support the rest of the stuff can wait

Thanks

kevin
[G Tablet General] roebeet:
Advantages of 2.0.0 is that it might be a bit more stable than 2.2.0, mainly because of the lack of the performance pack. 2.2.0 is definitely a significant speed improvement, but it might be a little more unstable going on some of the posts I've read over the last day or so.

I personally use 2.2.0 as it feels fairly stable for me, at least so far. The speed improvement really is significant.
[G Tablet General] kevin stone:
Thanks are the other ones still posted somewhere?
[G Tablet General] roebeet:
Yes, you can reference the first post, in this thread.

2.0.0 and 2.2.0 are "full" updates - in other words, they are the baseline mods. 2.0.x to 2.1.x are supplements for 2.0.0 (if you want to use them) and 2.2.0 does not have any supplements, yet.
[G Tablet General] :
I noticed the app disappearing issue as well, but after a few minutes, they appear again. For example, Shortyz crosswords app on main screen, using LauncherPro, the icon changes to unknown, then changes back to correct icon. However, the app still works while the icon is not correct.
[G Tablet General] kevin stone:
2.2 and dead

I just did the 2.2 and all seemed ok until I did the data wipe as recommended.

first time I got a bunch of fc's so I did the power buttom volume up thing and now all I get is the viewsonic screen and gtablet screen alternating back and forth and I have no way to get back into the tab to reload anything :(
