Yeah. I thought it was some confusion of this sort.

What you're talking about is bad blocks on the NAND-flash device. Those bad block messages that the kernel prints are all from the built-in NAND device, and not from the SD cards. The internal SD card is a different device with completely different operating characteristics. Specifically, all SD cards have HW circuitry and firmware which does bad-block remapping, block translation and wear-levelling. So, any bad blocks, if they are present on the SD cards, will be quietly remapped by the card itself. And, if there are problems with the SD card, it will be very clearly visible in the dmesg outputs, and when they occur cause "hangs" if you attempt to use the SD card in any way. It's a very unsubtle problem.

So, it is highly unlikely to be bad blocks on the SD card which are causing whatever install failures you describe. If it isn't bad blocks, then that leaves random data. For this scenario, consider what happens when you repartition the SD card:

1. CWM calls a /sbin/sdparted script with the partition sizes.

2. The script calls the /sbin/parted program to create partitions.

3. Right after this, the e2fsck program is run to check the newly created /data.

4. The /data partition is again checked when the ROM is booted. So is the other partition on the SD card: /mnt/sdcard.

5. Newly created filesystems are empty because all meta data--block bitmaps, inode tables, superblocks, journals, FATs, etc--are all freshly written.

How can data persist after all this? In fact, you can test that repartitioning is a very reliable operation: Its easy to write a shell script which will loop N times creating 2 partitions on the internal SD card, filling it will random files and dirs., then repartitioning and checking to see that all data has disappeared from both partitions. I'm very confident that if you run such a script on a boring Sunday afternoon, say, it'll come back clean every time unless you set N to some outrageous number and wear out the SD card.

I don't know what all this is, but, its very vague and not relevant to our little discussion which is on the supposed benefits of double partitioning and the utility of redundant steps.

Again, not relevant to the discussion, and, more than a little ironic considering that you are a member of the Flashback team.

Not just in "theory"--whatever that means in this context--but, in practice too, which is what prompted all this.

Cancer?! Oh, boy...

No, it's not to "prove my superior Android knowledge"; its as you said it: "education people", or, as I would have phrased it: providing factual and useful information and not simply internet rumours.

How is providing inaccurate information and persist in doing so in the face of contrary evidence "helping people"?

Now this is getting silly. Me, the cause of XDA's "bad rep"? Must've been a bad day for XDA when I joined up, right?

Oh, I'm not mad, just slightly eccentric.
[G Tablet Android Development] gnac:
So I am having a couple basic problems.

First, how to get the update files into the root directory? Are you folks putting the files onto a removable microsd card on you pc and then moving the media onto the tablet? For the time being update.zip is located at /sdcard/

Second, and perhaps more importantly, when I power off, holding the power and col up buttons doesn't seem to bring the system to the stock recovery. I briefly see the android logo, and then a blank screen. It appears to have powered off again.

Third, I tried hooking up the system to a pc with and old male to male usb cable I found, but adb cannot find the device, and the device gives me no indication that a connection has been made, do I need a specialty cable?

Thanks,
[G Tablet Android Development] rajeevvp:
See this video: https://www.youtube.com/watch?v=mY_FvJnWNEw

It should answer most of your questions. Note that the user is on a 1.1 bootloader. Most current gTabs come with a 1.2 bootloader. Each bootloader version needs a version of CWM and ROM that is compatible with it--ie. 1.1 bootloaders need a 1.1 compatible CWM and ROM. Make sure whatever you're installing is for your bootloader version.

See video.

Did you install the correct version of CWM? CWM-2.5.1.1-bekit-0.8 or CWM-4.0.1.5 for 1.1 and CWM-3.0.2.5rev5 or CWM-4.0.1.5 for 1.2?

Use the cable that came with the gTab.
[G Tablet Android Development] Rochey21:
I never noticed that CWM was different for 1.2 and 1.1. I currently have 1.2 and tired to install CWM which was the wrong one.

When I try to enter recovery, I get a message of " booting recovery kernel image"

I can turn it off and enter into the stock rom no problem.

Any help would be great to how I can undo this and install CWM.

Used the link for CWM from step 1 from this LINK

Thanks very much.

Not sure if you got this fixed or not, but I ran into the same problem. I just now got around to updating to 1.2 and didn't realize there would be a difference. Hit this link- http://xdaforums.com/showthread.php?t=1288253

If you need to nvflash anyway, just rename the image part9.img and replace the original.

[G Tablet Android Development] Andronick:
Success!

I followed the procedure and everything worked out fine!

You sold a Gtablet for Viewsonic with your explanations! Otherwise, I would not have bought it!

Great job, easy for a Noob like me.

I just wish I knew why these steps were necessary but hey, you can't learn everything in one go!

Thanks again :D:D:D
[G Tablet Android Development] MDMTahiti:
I'm having troubles. I followed all steps - worked great. Decided to try the VegaN1.0b2 ROM. Followed the steps again. When it boots now, it keeps asking to touch the droid. I do and nothing happens past that. I followed the steps carefully to partition the SD. It still boots the same looping at the touch the droid. Now I have no way to change the ROM file on the gtab. I seem to need a driver so my XPSP3 machine can read it - it only shows empty directory and the install of the device said it had a problem. Please help!
[G Tablet Android Development] festivus:
Is the step-by-step install guide posted in the forum the same whether you choose TNT or Vegan? Will be attempting the install soon, and just don't want to screw it up. From a compatibility and useability standpoint, does one Rom stand out between the two? I think I would rather go for more reliability rather than chase down the last bit of speed at the expense of fc's, apps that don't work right, etc.

Any advice is greatly appreciated!

Help

Thanks for making such a great install thread... :D

I performed the steps and everything was working great, including market.

I tried to install Adobe Reader and had a force close of the app.

Now I'm stuck in a boot loop :eek: :eek:

I can reboot into ClockWork

Any suggestions other then starting over?

Thanks in advance!!

White screen freeze

I am new to android and followed this guide the other day to flash my G tablet to TnT 2.2. I am having one issue after the flash.

Every once in a while the Tablet freezes up and shows only a white screen until I turn it off and turn it back on. It did it about 3 times in one hour last night, while I was surfing the web. Has anyone else had this problem? Is there a way to fix this?

Thanks in advance
[G Tablet Android Development] csamy:
I completed Parts 1 and 2 successfully, but can't do part 3. Specifically, I can't get into settings. Nothing happens when I select "settings". The grey bar appears at the bottom if I press the list icon (whether on screen or via the button itself on the panel), but when pressing settings, it highlights as if its about to open, but then nothing happens. Therefore I cannot do part 3, step 3.

Tried rebooting, problem still happens.
[G Tablet Android Development] threedfreek:
New to the g... I want to keep the current crappy OS by backing it up with CW. If I do that will I be able to reset the system back to factory? I haven't installed the 101 update yet... if I save that will it completely overwrite any changes I make here? Thanks for any help!
[G Tablet Android Development] TaterTot24:
Same thing happens to me...
[G Tablet Android Development] csamy:
Well I found a workaround. The alternate way to get into Settings is to simply go into the Applications menu (from tapping on the list icon located on the right side of the desktop screen), and then choose Settings from there.
[G Tablet Android Development] pfowler79:
HUGE thanks to everyone who made this mod and the guide possible. As an android noob (other than using my stock Evo 4G phone), this stuff has been amazing. Great walk through. Great device! I turned mine on and used the stock OS just to confirm that all the main functions (touch screen, sound, etc.) worked before flashing... and boy did it SUCK! Now I can wrap this up and give it to the wife for Christmas knowing it's going to work, and work well.

As a side note, in addition to going to the Settings app in the App List, I found that you can also search for "Settings" in Google search bar on the main screen and get at it from there. Odd though, that it isn't accessible from the main screen pop-up on the bottom. As others have said, looks like it accepts the tap to select it, but nothing happens. Small annoyance for what you get with this mod.

Lastly, I'm not sure that I actually got the Market Fix to work. I never got an error. But, since I already have a Google account that has been used successfully on my cell phone, maybe that lets me use the Market without the mod? Or, maybe the mod worked and I just didn't get an error? Regardless, I have full access to the market and any app I've searched for thus far downloads and installs fine.

Anyway, so far, so good. Thanks again!

Got New G-tab Taday

Picked up G-tab today and was following the guide however I cant get pass installing CWMOD_v08 I hold both the power and vol up button and let go when the screen with the paroits is shown. Then in the top left i get the text "Detect recovery key pressed" and then "Booting recovery kernel image" then a flicker of the screen followed by a exclamation point inside of a triangle. I tried this several times. I used three different sd cards. Is there anyone who can help me with this. I dont think Im the only one with this issue. Thanks
[G Tablet Android Development] roebeet:
Standard recovery needs an update.zip on the root of your /sdcard, and a /recovery/command file in your /sdcard as well. Most of my mods have this structure in the zip/rar I supply, so you can just extract it and drop the contents into the mounted drive, on your PC.

the /recovery/command file seems to be a way to tell recovery where the update.zip is located, so it can run it.
[G Tablet Android Development] pfowler79:
I had this issue as well. I can tell you what worked for me, and you can give it a try. After copying the unzipped Clockwork Mod to the root of the SD Card (not inside any folders), I saw the "detect recovery key pressed" briefly before the big exclamation point showed up. Just to cover my bases, I put the microSD card in my full size SD reader, inserted it into my laptop, and reformatted the card (in FAT32, I believe). I then redid the "extract clockwork to sd card" part, confirmed that the card had both the file and folder it was supposed to, put the card back in my G-Tab, and fired it up pressing the power/Vol+ combo. That time I VERY briefly saw an image of a box with a green arrow, then the tab restarted. Had to let it get all the way to main screen, shut it down, then restarted with the Power/Vol+ combo again and Clockwork came right up.

Not sure if this will help or not. Since you tried several different SD cards, you may have tried formatting them as well. If not, pop one into a PC card reader and give it a go. Good luck!
[G Tablet Android Development] gregjones5947:
@ pfowler79 and roebeet Thanks to the both of you. Both you guys said the same thing pretty much. I UnZIpped from the file "CWMOD_v08" placed the two folders "recovery" and the "Updatezip". on the SD card without having it in a folder. Then I

repeated the steps in the guide and it worked. I then went slowly and followed the rest of the guide step by step reading each line twice as I went thru, and it worked. I know have TnT lite with flash and Market. Thanks

hi i purchased a g tablet through amazon and have been trying to install just clockwork for starters and cannot seem to get it working for the life of me. Could some one please make a video or maybe just re explain how to install clock work with a little more detail? if so I would honestly cry tears of joy because i am having such a hard time installing this< i have a 4gb micro sd that comes up as DCIM and have extracted the zip file to the dcim 4g sd card and have tried them in a bunch of different combinations when i hold power and + it just boots up then gives me a exclamation mark in a triangle.

Stuck at Part 2 Step 9

As you can guess a noob here. Followed the steps to the tee (I think!!). Part 1 got done right. For Part 2, I created a folder on my SD Card called "New Folder" and copied the TnT Lite 2.4.0.zip to this folder.

Followed Part 2 to step 8 (unmount /system and /unmount /data). All seemed good.

But for step 9 when I go to “choose zip from sdcard” it shows me all the folders in the /sdcard (including 'New Folder'). When I select 'New Folder', it says "No files found". And I'm stuck at that. My hunch is I should not have had a space in Folder name, but what do I know.:confused:

Is it OK now to power off (if folder name is the issue, to go back to file explorer to rename it and start from Part 2 Step 4 again.

Thanks a lot for your help.

Resolved the issue. I was trying 2.4.0 version of TnT Lite. That rar file was corrupted. Used the Tnt 2.2 version and everything went as explained. Great instructions. Got Market and Flash working. Thanks mate

only 256MB cache possible :-(

Hi to all,

sorry for the question but I did not find any answer.

When I repartion the SD card in .08 I only get the choice of max 256 MB swap.

But I heard here anywhere that somebody already used 512 MB swap.

How is this possible ?

Thanks for the tutorial

This was exactly what the doctor ordered. Finally I begin to understand how things are put together and how to modify them without the fear that I will somehow brick it or break it without being able to fix it. Case in Point....the first Viewsonic update broke my Weather app and when I asked tech support they told me to "just download a different app". Not really what I wanted to hear.

My rom managr/clockworkmod was not working but someone else's error lead me to V.08 which fixed it and now I also have backups working. Once a tweak-er can recover from their latest round of changes it opens the world to more research and play.

Well done

[G Tablet Android Development] rothnic:
Nice guide, here are some comments:

Clockwork install: Modifying the command file to point to the external sdcard might be troublesome for new owners who do not have a sdcard. People with an external sdcard can also use the internal storage with no problem, so I think internal should be the default.

TnTLite Install: This section could be changed to install custom rom. Then you could list Cyanogen, TnTLite, Zpad Clean, and Vegan and where to find them. We get lots of questions about will your guide work for Vegan.

Bootloop: You might consider not recommending using the 4096 option. That is an hugely big space for app storage. It might be hard for anyone to use that much. 2GB might be a more reasonable recommendation. Additionally, since android doesn't use swap, then second option should be set to "0".

I tried using the stock ROM for a few days, but (with much fretting about doing something wrong) followed your steps. I have never been happier. Your directions were just what I needed.

I would recommend this tablet to everyone - great hardware and now great software!

Did Part2, step 6! Had been holding my breath for 12hrs between Part1 step 4/5. I had a spotty clockwork download: meaning I had the update.zip but not the recovery folder (with the script in it). FYI, if your recovery folder is empty it doesn't work (duh). Downloaded and copied again, this time instead of flashing the /!\ symbol and rebooting, the install started. I loaded the VegaN b3 ROM and had to do the extra mount steps you stated. Thanks!

Take into account this is my first time flashing this type of device.

When I try to reboot into recovery..I see the notice , it looks for the kernel recovery ...then i get a big fat triangle with an exclamation point...no boot up into clockwork mod.

When I try to just reboot into recovery from within ROM Manager Premium (aka Clockworkmod v 2.5.1.4 with the base of clockworkmod 3.0) nothing happens.

Any help you can lend would be greatly appriecated.
