[G Tablet Themes and Apps] Alpha06:
Thank you SO MUCH

# 7 worked

Now my question is: while I was flashing to #6 (wrong directory)...did that screw anything up file structure wise etc??? :confused:
[G Tablet Themes and Apps] rayden25:
Good question. Mine seems fine and I flashed it about 20 times. I formated it too! LOL!
[G Tablet Themes and Apps] WickedStyx:
#7 worked for me as well. Thanks.
[G Tablet Themes and Apps] original G:
got home and restored everything. tried again using partition 7 and boom! I love the new logo. Thanks everyone!
[G Tablet Themes and Apps] Alpha06:
Haha, thanks so much for this guide.

Just me having some giggles

If anyone wants the black tegra image let me know
[G Tablet Themes and Apps] FateZero:
May I please have your boot logo
[G Tablet Themes and Apps] Alpha06:
Sure thing

[G Tablet Themes and Apps] cnathanw:
Maybe a "little" more indepth help needed here.

OMG OMG OMG I got it to work! It took me 3 days of answering my own posts...sigh. Learning's the curve right? The first post here advises to follow a link to install NvFlash, but that link really only shows the SDK and install it. I've followed several links around to get the Nvflash_gtablet file and the Nvflash_windows file. Be sure the NvFlash_gtablet zip you get has the correct "usbpcdriver" folder in it. If that folder isn't there, its the wrong file.

First and foremost - you can't do this on Win7! It finally clicked to jump on my XP laptop. Install the SDK. Do the Volume - and power button to go thru birds to black screen (with your USB cable plugged in). The APX found will pop up on your PC and the driver is in that nvflash_gtablet folder on your PC under "usbpcdriver".

Once that's done then you can go back to the nvflash_gtablet folder on your PC, get a command prompt and run the command. (make sure your *.bmp file is in that folder) I got my tablet December 27th or so. It worked indicating Partition 7 in the command. Voila!

Trying to "re"find the link for the nvflash that included that usbdriver folder - I'll post when I find it again.
[G Tablet Themes and Apps] daname:
nvflash process clarification, please

I am assuming that the process to replace the boot logo for any G-Tablet (VEGN-TAB included) from a Linux system is as follows:

1. Connect Linux system to gtab with USB cable.

2. While pressing the "volume -" rocker key down, press and hold the "power on"

key until the gtab screen turns black again.

3. Run in a Linux command window:

sudo ./nvflash --bl bootloader.bin --download 6 my_new_boot_image.bmp

4. Reboot gtab

I am using bootloader.bin from: nvflash_gtablet_2010110500.zip

and nvflash from: nvflash_linux_2010110500.tar.gz

Is this likely to work?

Is there some way to look/check first to make sure that the boot_image.bmp is to go in partition 6 and not partition 7?

EDIT:

I have answered the process questions by running the following statement.

$ sudo ./nvflash --bl bootloader.bin --getpartitiontable gtab_partition_table

The partition table on my G-Tablet looks like this:

...

PartitionId=6

Name=MSC

DeviceId=19

StartSector=2688

NumSectors=8192

BytesPerSector=2048

PartitionId=7

Name=BLO

DeviceId=19

StartSector=10880

NumSectors=2048

BytesPerSector=2048

...

Do you think BLO stands for boot logo?

Could someone that has successfully changed their boot logo run --getpartitiontable and tell me your result and what partition number you used and when you made your change?

EDIT EDIT:

I installed the logo to partition 6 (wrong choice) and then partition 7 (I should have gone with this one first!) and it now works so I am guessing that the BLO does stand for "boot logo".
[G Tablet Themes and Apps] seymour_butts:
i also flashed partition 6.. and nothing...

then i did it to 7 and got it...

what about partition 6 now? have we screw things up? anyone knows?

soon i entered the system i got "android.process.acore" FCs... everytime i reboot..

any ideas?
[G Tablet Themes and Apps] seymour_butts:
hum... i think i've got the FC resolved...

disabled sync, then cleared contacts storage.. reboot and enabled sync.. FC seem to have disappeared.

so... partition 6? Maybe we have done something bad????? :D
[G Tablet Themes and Apps] seymour_butts:
Hum... Now gmail FCs...

Nvflash commands

I looked online for a tutorial on nvflash... commands for pulling partition table info, saving and restoring partitions, but didnt have much luck. Can anyone point me to a resource? Id like to get rid of the birds but I dont want to just cowboy up and risk bricking this thing.

[EDIT] I found this post... http://xdaforums.com/showthread.php?t=861950 which has a lot of the info I'm looking for (search is your friend). I'm going to play around with APX mode this weekend. Can't wait to get rid of those birds, but I'd still like to know the syntax for creating a restore img for a specific partition in case something goes bad. Can anyone help me there?

[EDIT EDIT] I got it. Thanks to JimCPL for his post in the general forum... http://xdaforums.com/showthread.php?t=914039&highlight=nvflash+windows and for pointing me to it from the IRC. I'm sporting a cool TegraII logo on powerup now (my BLO was also partition 7). It seems like most of the GTabs may be partitioned this way?!?! I highly recommend everyone run the getpartitiontable command in APX mode via NVFLASH to confirm this before they download their images.
[G Tablet Themes and Apps] digitalslacker:
got it! thanks for your post daname, that helped me a bunch.
[G Tablet Themes and Apps] doihaveto:
Why would my pictures not be working

i can load the pic logos i download on here but if i alter them or make my own logo from scratch i get a blank dark screen, which dont get me wrong is better than the birds but id like my own logo.

i am currently using the one with droid pissing on the apple

any specific specs i need to be following that would make my altered or created pics not show up (blank black screen) but the ones others have made and I have downloaded do?
[G Tablet Themes and Apps] lifeisfun:

My BLO partititon is also #7 NOT 6
[G Tablet Themes and Apps] seymour_butts:
ok.. some more feedback..

When i first did this the partition I had to flash was 7 and not 6...

Then i had a problem with rom manager and had to do a full restore with nvflash like mentioned here http://xdaforums.com/showthread.php?t=861950

Today I went again to flash and put my image there and bum.. wrong partition.. it was not 7 like before, but 6... Must have been cause of the original image available here https://www.dropbox.com/s/wrcd87u1iy31u4e.

ok.. so then i tried again... flashed partion 6 and it worked again...

now i have the same problem.... What could have happened when i flashed wrongly the partition 7??? I already asked before but got no answers here...

Aparentlly the tablet is working, but some must have changed when i flashed the 7 instead the 6...
[G Tablet Themes and Apps] doctorisin:
Seymour... If you look at flash.cfg in the nvflash directory you used, it shows you the partition table, so when you did the restore, it set up your tab with the BLO in part6 (it was in part7 before). You can use nvflash to write just part7 (kind of the same way you did with the bootlogo) using the part7 image from the nvflash directory if you dont' want to do a full restore.
[G Tablet Themes and Apps] seymour_butts:
just to see if i got it right...

u are saying i can just flash part 7 again, just to be sure nothing got messed up? that's great...

but how's the command? when i flashed the logo I did:

nvflash --bl bootloader.bin --download 6 (imagename).bmp

and when a full restore i just did

nvflash_gtablet.bat

don't take me for lazy for asking... hehe.. I'm just leaving work to go home and if u know it, great, else i'll do some searching later on..

thanks
[G Tablet Themes and Apps] lifeisfun:
What command would you use to restore only individual partition ?

Thanks
[G Tablet Themes and Apps] lifeisfun:
Anyone ?

I would love to know how to flash only one partition.

Thief beware...

It's a nice place to write your name, phone + email since the logo survive a regular rom replacement!
[G Tablet Themes and Apps] the3dman:
Just so everyone knows, any image I put that was larger than 1.8mb showed up as a blank image, so I had to compress them down first to 1.8mb or less.
[G Tablet Themes and Apps] the3dman:
I believe it would be this (just my guess from reading about nvflash), but I am not responsible if that does not work.

nvflash --bl bootloader.bin --download 7 part7.img

[G Tablet Themes and Apps] notwen:
Sweet. I think I will change my boot logo as well. Thanks to all who have contributed to this thread. Here's to hoping that "BLO" does indeed specify your bootloading partition. =]

[G Tablet Themes and Apps] jdub1911:
OMG I finally got rid of the birds after 3 hours. After tracking down the right files, I was finally able to get my photoshop'd file to work off of the op's original tegra file (for some reason had to leave it named tegra.bmp). Thought i'd post up and share what finally worked for me. The only thing i could use from the OP was the APX usb drivers, then I had to use everything else (nvflash.exe, dll's and the bootloader) from the nvidia download site .msi file. Hope this helps!

[G Tablet Themes and Apps] JOE3PO:
Thanks for the info guys. I've been reading all of these threads for the last couple of days, & It was overwhelming at first. But I think I'm getting hang of it. I'm waiting on my Gtablet still, I should get it the beginning of next week. I think I should be well prepared by then after reading all these threads a few more times between now and then.

But this is def. one of the things I must do, I don't even have my tablet yet and I'm sick of those birds ... haha ... I took a break from all the reading & created my own Boot Logo ... Kinda stoked to put it to use.

Thanks again for the info guys
[G Tablet Themes and Apps] trindog01:
Hoping someone can help me out here. I have followed all of the instructions and even made sure that 7 is the partition that it is stored on. When I run the command

"nvflash --bl bootloader.bin --download 7 bootlogo.bmp"

it states: "Nvflash started"

but I don't get a response after that, it just seems to hang. If I reboot nothing changes and the image of the birds is still there. I tried this several times BTW. On one hand I am happy that the tablet is still working, but I can't seem to figure out why the system keeps getting frozen when I enter that command.
[G Tablet Themes and Apps] wd5gnr:
Do you have usb drivers for windows or the udev rules for Linux? Search for nvflash setup instructions.
[G Tablet Themes and Apps] trindog01:
It's the windows drivers, for some reason all of the other commands work it's only when I try to flash the startup logo it hangs up.
[G Tablet Themes and Apps] wd5gnr:
Maybe you should reformat partition 7? Nvflash has an option for this. Just be careful not to pick the format all one. I had a problem reading my msc partition and a format and reload fixed it.
[G Tablet Themes and Apps] trindog01:
Tried it again for the 5th time and it worked. I am not sure what happened but I didn't change anything
[G Tablet Themes and Apps] gogorman:
Here is the one I have made, and am using. Looks great when the tablet boots up!

Feel free to use it on yours.
[G Tablet Themes and Apps] wd5gnr:
When I saved this as a BMP and loaded it, it looked "jaggie" -- I bet because of the JPG compression not saving the full range of black and instead using alpha. It looked good on the PC screen. Did you start with a BMP and export to the JPG? If so can we get the original source. I like the black background over the white one I have now.
[G Tablet Themes and Apps] JustMeToo:
My humble boot replacement.

BTW, mine was in partition 6
[G Tablet Themes and Apps] wd5gnr:
I never did get the black background one to show up right so I doctored the original white one. Attached are two files. One with a slight white border which looks nice (I'm using it now). The other solid black. Both ready to flash.
[G Tablet Themes and Apps] megabyte2365:
Installed!

I tried 7 first since it seemed to be the most popular location and nothing so I went to 6 and it worked. Thank you! Now I need to figure out how to remove the gold ANDROID between the boot screens.

Mine was a Woot and of the 10,000
[G Tablet Themes and Apps] wd5gnr:
While I am glad it worked out for you, you should not randomly flash partitions! In every case I've seen either the logo is 6 and the misc partition is 7 or vice versa. However, that doesn't have to be true. And it is still not clear to me what the effect of flashing the misc partition is. It appears it gets rebuilt so it isn't the end of the world.

Please, please, please use nvflash to dump the partition table an examine it. Then ONLY flash to the BLO partition.
[G Tablet Themes and Apps] CodeNinja:
Ok, I'm having fits here.
[G Tablet Themes and Apps] CodeNinja:
Nevermind, after doing an nvflash restore to 3588 everything started working. :)

Although for some reason it wouldn't take more than a 1.12mb file.
[G Tablet Themes and Apps] fosser2:
thanks for all the help. I was able to get mine to flash just fine and I'm a noob! Mine was actually in partition 7. I flashed partition 6 twice and noticed that marketplace reset and my widgets crashed from flashing to the wrong partition. I was able to get them reset without reformatting the flash. My tablet was from WOOT just for the 10k people who got them, you will most likely have to flash to partition 7. Hope this helps and hooray! first post :)
[G Tablet Themes and Apps] cd112:
Hey All,

I tried doing this last night on my TNTlite 4.40 Rom. I created a folder and unzipped all the NVflash files and included the tegra.bmp in a folder called picx on the root of C:\.

Then i opened the command prompt and cd \ over to the c:\picx directory that holds all the files.

This was the original Command

nvflash --bl bootloader.bin --download 6 (imagename).bmp

this is the command that i ran:

nvflash --bl bootloader.bin --download 6 tegra.bmp

it looked like this in the command prompt:

c:\picx>nvflash --bl bootloader.bin --download 6 tegra.bmp

the command ran successfully and it said copied successfully and then on gtablet it showed this once it was done. ("entering nvlash recovery mode / nv3p server")

I rebooted and the stupid birds are still there.. Am i doing anything wrong.

Any suggestions would be helpful

thanks again

cd
[G Tablet Themes and Apps] wd5gnr:
Most likely your birds are in partition 7, not 6. However, you should not blindly flash a partition.

Run

nvflash --bl bootloader.bin --getpartitiontable parttable.txt

Then go look at parttable.txt and see which partition is BLO. It must not be 6 apparently.
[G Tablet Themes and Apps] marcos6:
Thanks wd5gnr for the wallpaper and helpful advice on using nvflash! Now there's no more semblance that this is a Viewsonic device (since I bough the skinomi carbon fiber to cover the back side of the tablet). This forum rocks!

Because bootloader.bin file is missing.

thanks, for some reason the bootloader.bin was sitting the C:, i must have accidentally dragged it out of the folder or something.

Btw. With that NVFlash command is there any chance of the partitions being messed with?

Only reason i ask is cos i booted up my Gtab after giving up on the logo and everything started force closing, launcher, email and a bunch of other boot up apps

I just repartitioned the SD card using CWrecovery and I'm restoring a backup. I'm just curious to see if that is what happened

[G Tablet Themes and Apps] rajeevvp:
It turns out that there is a much easier way to replace that first splash screen: Just write a new .bmp file to the "bootbmp" partition using the flash_image program (either in CWM or in ROM. Note, however, that not all flash_image programs will do the job correctly--the one in the attachment works fine).

As a proof of concept: flash the zip file in the attachment using CWM to get a new initial splash screen.

If you want to roll your own, then just replace the bootbmp.bmp file in the zip file with another 24-bit 1024x600 MS-Windows bitmap file.
