I guessing I'm doing it wrong because I still have the static before the boot animation.
[Galaxy Tab 10.1 Android Development] Grommish:
Backup your SDCard. This WILL wipe it..

Download the "Files for Dummies" pack (in this thread I believe).

Download the Stock HC3.01 ODIN file

Download Kernel of your choice - Recommend Pershoot's, Make sure you have the right one for your tablet!

Download ROM of your choice, though I recommend the Stock OTA CWM Flashable 3.1 TouchWiz

1) Copy the SDCard to your Machine

2) Flash Stock Recovery via ODIN

3) Boot to Stock Recovery - Factory Wipe - This WILL delete EVERYTHING and Format the SDCard.

4) ODIN CWM back to Recovery

5) ODIN HC3.01 Stock File

6) Boot Tablet, let it shake down. Connect to USB, Copy Kernel/ROM CWM Zips to Card (KiesAir/MTP/Whatever)

7) Flash ROM, Immediately Followed by Kernel without Restarting

8) Boot - It'll take a while this first time out. Re-Setup Tablet info and Sync.

This will set the tablet back to stock and recondition the internal storage. If you have Complete "I have to return it" stock, do steps 1-7, without Kernel flash and using the HC3.1 OTA CWM, then Re-ODIN stock recovery. This will remove CWM and be on stock ROM.

+1 is there a solution ?!!!

Please im stuck
[Galaxy Tab 10.1 Android Development] Grommish:
No. You are hosed. Take it back, get an iPad2. They dont require special things, like reading.

If you can get into nvflash mode you can get into download mode. If you cant get into either, you are screwed and need to return it. Since you seem to actively refuse to read or learn, i wish you the best of luck with it.
[Galaxy Tab 10.1 Android Development] marksnet:
Funny i still have my G10 but i also got pissed and got an ipad2. +1 to you brotha!

I like the g10 but grow very tired of buying the latest and greatest android stuff only to discover

My Tab seems bricked, and won't turn on.

I've gone through the guide and tried but I'm getting USB Write Failed.

Any ideas? Next up will be the battery drain but will take so long and may not work.
[Galaxy Tab 10.1 Android Development] Grommish:
Silly, but did you hold the power button for 20sec? Also, may want to try holding the power & vol- and plugging in to the wall (not PC).
[Galaxy Tab 10.1 Android Development] Smithyster:
Thanks for the suggestion but yes I have. Tablet got stuck during formatting system, and since won't turn on.

okay I get always down to section 17. With nvflash and tablet boots normal and everything works fine on task ics rom then when I reboot or power off it will not power up unless I nvflash agin ... any suggestions ? And is there any way to get to down load mode thru nvflash so I can odin back to stock? Im new to nvflash

------i have the same problem......hope fix will come out soon...I have galaxy tab10.1

i mean these error

---------- Post added at 09:26 PM ---------- Previous post was at 08:59 PM ----------

Just got my tab power back on...after a 2 weeks of not using it.....

I tried this idea but it dont work with my gtab 10.1 wifi....i got the error 0x4

but i tried succesfully powering it up.
[Galaxy Tab 10.1 Android Development] johnccc:
Thanks for this tutorial.

It didn't work for me because I have the 0X4 error, protected. I'm sure it would have worked otherwise.

Just wanted to ask, Is there anything working for the protected ones yet, thanks.

Normal power on results in "Download Mode", I can get into APX by unplugging USB, pressing and holding power + vol up for 15 or more seconds, then connecting to PC. The screens stays blank the whole time, when holding power and vol up and even after successfully connecting to pc and seeing APX in device manager.

In normal power mode, for me, "download mode", I can connect using odin, but I cannot write anything to the tablet. Everything is good until it attempts to write.

I have problems doing this from a 64 bit Windows 10 installation. I get the following:

C:\nvflash>nvflash --bl bootloader.bin --go

Nvflash started

rcm version 0X4

Command send failed (usb write failed)

I tried a couple of times, including after a reboot and it fails at each attempt.

The driver installation was OK. I see it in Device Manager, it disappears right after issuing the nvflash --bl bootloader.bin --go command.

Any ideas?

[Galaxy Tab 10.1 Android Development] madsquabbles:
thanks. i was gonna try that but wasn't sure if it only applied to back up or not.

going to next step.
[Galaxy Tab 10.1 Android Development] nagmier:
First off thanks for the effort everyone is putting forth on this...

I downloaded nvflash from post 2, and pershoots i/o bootloader from page 2...

followed the instructions all the way through section 1 no problem, section 2 was perfect up until #18 as soon as I type nvflash --sync and press enter I get

Nvflash started

rcm version 0X4

Command send failed (usb write failed)

As soon as I hit enter the Tablet disconnects from the PC and Drops back to Cmd prompt. I have to press and hold the right vol button and power for 15 seconds then plug in the usb to get it to show back up in device manager as "NVidia USB Boot recovery driver for Mobile Devices"

Am I maybe missing something or is this maybe because of the locked bootloader?
[Galaxy Tab 10.1 Android Development] pershoot:
you should backup your stock recovery prior to flashing a different one in (just as a force of habit), at the very least, once, then go nuts, hehe.
[Galaxy Tab 10.1 Android Development] pershoot:
instead of sync do this:

nvflash --bl bootloader.bin --go

then carry on with backup of your recovery and flashing in a new one.
[Galaxy Tab 10.1 Android Development] shep211:
All the commands run pretty fast. If it every stops at starting nvflash then it needs to be restarted. Hold down vol up then power and wait for a beep then run the command again. For some reason the --resume command does not work right in windows. I ended up resetting nvflash after every command. Why it stops is because bootloader.bin is already started and if you run bootloader.bin command again it will stop at starting nvflash.
[Galaxy Tab 10.1 Android Development] madsquabbles:
yeah, i didn't back up my bootloader since he included one. after actually backing mine up and using --resume it went fine.

now to root.

thanks!!!
[Galaxy Tab 10.1 Android Development] shep211:
there is no 18 partition. It goes 2-17.
[Galaxy Tab 10.1 Android Development] nagmier:
I get the exact same result
[Galaxy Tab 10.1 Android Development] madsquabbles:
well that's weird b/c resetting wouldn't work for me. it would just hang each time at "nvflash started"

after using bl bootloader and then resume everything went fine.

i'm using w7x64 home premium.

so i guess if resume doesn't work then do a reset and vice versa. either way backing up your bootloader should come first.
[Galaxy Tab 10.1 Android Development] pershoot:
take a nandroid backup and flash the latest tools pack.

this will give you su/busybox/misc utils + root boot.

[Galaxy Tab 10.1 Android Development] nagmier:
ok I'll try it one more time before I have to bail and grab my kid
[Galaxy Tab 10.1 Android Development] shep211:
No its not done. You should get output on every command. Just reset nvflash after very command to make sure it works.

1 run command

2 wait a few seconds for it to finish

3 hold vol up and power until you hear a dos beep

4 run next command

5 wait a few seconds for it to finish

6 hold vol up and power until you hear a dos beep

If it gets stuck on starting nvflash for a few seconds then it needs to be reset again.
[Galaxy Tab 10.1 Android Development] madsquabbles:
finally rooted! thanks everyone!

hope we get some kind of lagfix soon. the delayed inputs are killing me. especially when scrolling webpages.
[Galaxy Tab 10.1 Android Development] shep211:
Ya some people say resume works and some say it doesn't work. Win 7 32 bit and resume would not work. If we have people report what works for them and what os they have we can create scripts for winy 32 and win7 64 for what works best.
[Galaxy Tab 10.1 Android Development] shep211:
I just tested this and it worked a lot better. I updated first post. I hope this makes it easier. Thanx

Good morning bierma32.

Thanks for your response.

My biggest problem is that I can't go into Download mode, the tablet goes into APX mode.

Greetings

Thank you a whole lot. From reading your first post - you didn't get much sleep. I am this way as well. If I start a project, I will work at it until it is complete.

edit:

To save some obvious time, I have restarted the device multiple times I have tried disconnecting everything and starting over. I even reloaded the driver.

Anyone else having this problem? if so anyone on the form who already downloaded please reupload to another media sharing site
[Galaxy Tab 10.1 Android Development] dsh897:
Do you have a lock symbol when u boot? U might be an unfortunate soul who got a locked one. I had heard news of this. If you do return it
[Galaxy Tab 10.1 Android Development] Dirrk:
I do not have a lock symbol when I boot.

edit:

And I believe you have that backwards. I believe if you have the Lock symbol its always unlocked if its locked there is no symbol at all. Which is what I have :(
[Galaxy Tab 10.1 Android Development] mongoose0318:
All steps ran fine but I can't seem to get into recovery. After finishing the steps in the first post, I rebooted and open up adb. ADB sees the device and when I type adb reboot recovery the tablet reboots but goes to the battery charging screen. Can anyone point me in the right direction?
[Galaxy Tab 10.1 Android Development] madsquabbles:
none of my other tegra devices would let you go straight into recovery. you have to boot holding volume down then push down select the android& box pic then volume up.

the tf does have some script or program that you can go automatically into recovery, but i think it's more than just an adb command.
[Galaxy Tab 10.1 Android Development] shep211:
3.1 has this issue. You have to turn off the device then hold vol dwn then hold power button. Let go of power when it turns on but still hold vol dwn (left volume button) it should go into recovery. I read 3.0 does not have this issue.
[Galaxy Tab 10.1 Android Development] mongoose0318:
THANKS! That did the trick. I just did a nandroid backup and am flashing to root tools as we speak. Great work on this.
[Galaxy Tab 10.1 Android Development] sdotA85:
Do we have to install the Clockwork recovery or can we just stick with the stock i/o recovery?
[Galaxy Tab 10.1 Android Development] bucketachicken:
CWR will give you better backup options.
[Galaxy Tab 10.1 Android Development] shep211:
You can stick with stock but you cant make backups in recovery. You could still root and do titanium backups in android. I really haven't seen anything yet that must have CWM.
[Galaxy Tab 10.1 Android Development] Dirrk:
Shep,

has anyone successfully done this with a "locked bootloader" I have been completely unsuccessful following these directions
[Galaxy Tab 10.1 Android Development] nagmier:
I wasn't able to after going through the instructions 2 times... I'm starting over 1 last time
[Galaxy Tab 10.1 Android Development] b-reezy:
It's seems mine successfully flashed everything following your guide.

But when i do 'adb reboot recovery' it just turns the device off and goes to the charging animation.

When I boot the device up it shows the pad lock and it is unlocked.

any ideas? :confused:

That tip worked for me! Make sure you pick the android box with the arrow to enter clockwork otherwise you will be in Odin and have to restart the tablet and try again.

you are the man this worked perfectly.

I'm trying this on the retail version with no unlocked symbol on bootup.

I completed section 2. I can see the NVidia USB Boot recovery driver in device manager.

But when i try NVflash --bl bootloader.bin --go , i get Command send faile (usb write failed) . I have made sure usb debugging is enabled. Anyone know why i get this error? (plz see attached thumbnail)

Worked great! Root on my retail 16GB GT! Used a Windows 7 Pro 64 machine.

Thanks for all the hard work.
[Galaxy Tab 10.1 Android Development] kirdroid:
Did your retail version had the unlocked icon on bootup?
[Galaxy Tab 10.1 Android Development] thesoundman:
Worked great for me. Root on my 16GB GT retail. Used Windows 7 Ultimate 64bit with no problems. Mine has the unlocked icon at boot.

Thanks to all those involved!
[Galaxy Tab 10.1 Android Development] used2hvatreo:
Same here, every detail. Loading up titanium right now. Thanks guys for getting this out. WELL DONE!
[Galaxy Tab 10.1 Android Development] blulite:
Does this turn a retail GT into an IO GT? Or is it just a retail GT with an IO bootloader? I guess the real question is what's the difference between an IO and a retail GT?

[Galaxy Tab 10.1 Android Development] ikon8:
Thanks, piece of cake. Works on Linux, you just need the nvflash linux binary. Here is nvflash for linux if anyone needs it.
[Galaxy Tab 10.1 Android Development] 00r101:
I bought a 16gb retail from BestBuy - It has an unlocked bootloader (or at least the unlocked icon on the boot screen). I wonder if the locked retail bootloader only on 32gb is a myth.
[Galaxy Tab 10.1 Android Development] insertnewsn:
Bump -- having this same issue. Retail 16gb white version (no lock symbol).. "usb write failed" error
[Galaxy Tab 10.1 Android Development] shep211:
This has i/o recovery only. I am working on custom rom and it may be based off of I/O.
[Galaxy Tab 10.1 Android Development] shep211:
I don't have a locked version to test but I will see if any of my coworkers got one on Monday. I pretty sure we can get the bootloader replaced. Once I get one to test I will see what I can do. It may need a bootloader.bin from a locked device and thats all to get the command working. When I used default nvidia development kit bootloader.bin the commands would not work. Once I replaced the bootloader.bin with one from unlocked galaxy tablet it worked.
[Galaxy Tab 10.1 Android Development] abmcbride85:
Yes mine had the unlocked icon.
[Galaxy Tab 10.1 Android Development] used2hvatreo:
I got my 32Gb version on Friday morning from Fry's. Upon boot shows the little lock symbol with a piece missing from the right side of the loop, i assume indicating unlocked. However, adb reboot recovery just put me at the battery icon, and the 3e recovery would not see the update.zip containing root.

all that fastboot stuff would not work for me as well.

took me like 5 minutes with the nvflash stuff and i'm rooted and backed up with tibu. looking forward to a customized ROM now.

@shep,

are you going to be able to put a video player in the rom, i downloaded a couple, but their stability seemed rather shaky.
[Galaxy Tab 10.1 Android Development] lostinbeta:
So I've repeated every step and I still can't get into recovery. I'm on Retail 16GB Metallic Gray version. If I hold Vol Down and power it jumps straight to Downloading mode and I have no other options. The screen just says

ODIN3 Download Mode

Reason: Force Key

Secure Mode: nonsecure

Check Signature:Check

waiting USB cable...

It seems to skip over a screen with an android icon but it flash right past it and I can't make it out. I'm not an idiot, and I've read and re-read to see if I'm doing something wrong, but it's just not working.

Edit: And now it just causes it to reboot. Vol Down is the left half of the rocker correct? (or is it not going in landscape mode, which either way isn't working...lol)

Edit 2: And now it works. Though I didn't do anything different. Wow...ok. Must just be one of those days.
[Galaxy Tab 10.1 Android Development] shep211:
Try reloading stock i/o recovery and make sure that works then try again. If all else fails reload stock retail recovery then try again.
[Galaxy Tab 10.1 Android Development] kirdroid:
Thanks bro....you are awesome. I'm glad to know you will look into it :-)

Edit: I have a locked version. I can post the bootloader.bin...let me know the steps on how to pull it.
[Galaxy Tab 10.1 Android Development] madsquabbles:
i'm asusuming that we can ue al custom roms that may come out for the io tab since we ahve the io ootloader now.

and will this also make us "unrickable" since we can get into apx mde and flash with nvflash?

srry for the typos hc sucks on this forum and i'm not anting to change themes... yet.
[Galaxy Tab 10.1 Android Development] lostinbeta:
thanks. it randomly started working, seems consistently working now. no idea what happened but i guess it doesnt matter at this point lol.
[Galaxy Tab 10.1 Android Development] jvanbrecht:
Worked great for me.. mine is now rooted.

Just a note.. ignore the volume up or down, rather refer to it as right or left and the power button.

Hold the device so that the buttons are on top, left most button being the power, and then the volume rocker button.

For recovery mode/download mode, it is power and left side of the volume rocker button. For APX/nvflash mode use the power button and the right side of the volume rocker button.

This worked first time for me.
[Galaxy Tab 10.1 Android Development] droxid:
So after some trying I realized I'm one of the unfortunate souls that has the locked version. I get that dreaded

Nvflash started

If there's anything that I can help, providing bootloader/dump etc I'll be more then willing. As long as there are instructions :P

I WANT MY ROOOOOT :p
[Galaxy Tab 10.1 Android Development] EvoXOhio:
Sorry if this has been asked already. Will this process erase all my apps and settings? When I had the xoom, the rooting process erased everything. Just wondering if this is the same. Thanks.
