Tried to root & bricked - on 2nd TM-900

Hello. New to this part of the forum but not to rooting Android devices (I have rooted my Galaxy Note 2, my wife's S4, my daughters Nabi Tablet and several HTC phones). A few days ago I got my 1st TM-900 (build KOT49H.T900UEUAND4) and attempted to root after setting it all up (naturally). I used Odin 3.07 and the procedure on Android Central which had me download the CF-Auto-Root-v2wifi-v2wifixx-smt900.tar.md5 file. I followed the directions and the tablet seemed to get stuck flashing cache.img. I waited for what seemed like quite a while and finally ended up pulling the cord - was unable to get into recovery/download mode to flash it back. Luckily I bought it 3 days ago and returned it for a new one. I really want to root, but now are a bit leery. I see where it says to flash with a SM-P900 file. Is this right and will it work with build T900UEUAND4 on a TM-900?

Also does it take it quite awhile to complete the process? the phones I rooted went quick, this took almost 15 minutes (or longer if I left it). I'm thinking I got "antsy" and should have waited longer on the 1st one. Can't afford to brick this one but feel naked without my root. Words of wisdom/advice for the second one?

One other thing. Are you on nb5 or nd4 build
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] midimench:
I was about to try what you did, and now I'm re-thinking it. This latest update came around about 10 days ago, so like you, I don't know if the SM-T900 tar file will bring me the same results as your brick brought you.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] michaelnmichelebuckner:
Odin header

My the version of Odin I downloaded has something similar (forget the excat wording) but if you look in the same folder/location as the Odin exe file resides you will see an Odin3.ini file - if you open it you will see that same text on the Title line - id did a quick compare between different Odin downloads and that seemed to be the only difference I saw. I edited mine to say Hello Michael.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] Desperado_22:
NB5 is written on the end of the build number.

Think I'll wait until the weekend then try to root again using an older xp laptop.

OK, was able to get out of the boot loop by installing a Stock ROM for the UK, then rooted after wiping the cache using the stock recovery, but now I can't see the 5GHz WiFi band. Can anyone tell me how to get the 5Ghz band back?
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] dodo99x:
Try a different 5GHz channel on your router.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] matthelm:
I don't think you read my post correctly. I have NO 5GHz WiFi band at all on the tablet, as if it only had a 2.4GHz radio.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] dodo99x:
Hmm very unusual. Flashing a rom from a different region shouldn't give you many (if any) differences in rom functionality. The only thing I can suggest is downloading the rom for your specific region. Or, you can intentionally try to soft - brick (by pulling your usb cable while odin is flashing Cache etc.) This will allow you to use Kies 3 emergency restore to download your original firmware (it will ask for your serial#) and flash your tablet back to stock original firmware.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] matthelm:
When trying to use Kies 3, I get a message about "Device is not supported ..." I can't win. :crying:
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] dodo99x:
Disconnect your tablet from the pc, using Kies 3, reinstall USB drivers under the tools menu. Reboot. Disconnect your PC from internet, then reconnect your tab via usb. Start Kies 3 and try again. (Disconnecting from the Internet prevents Windows from downloading drivers and forces it to use the ones Kies 3 installed.)

Success rooting t900.... finally.

Tried the same rooting method on my older Windows XP desktop PC yesterday (CF pack incl. Odin 3.07 and cf file for t900)

Took 10 seconds, first go .... no problems.

It seems my win7 laptop was in some way causing the problem.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] glensta:
Successful Root

Followed instructions, rooting worked perfect - thank you OP. I'm running a windows 8.1Pro Laptop with the standard cables and let windows install the drivers automatically. Now just waitin for that recovery to be developed :)

[Galaxy Tab Pro 12.2, 10.1, 8.4 General] sparks305:
I've been following this thread ever since it started up and have had no success trying to root my T-900, it always seems to get stuck at the cache.img part in odin then eventually fails. My next step now is using XP in vmware to try and load it. I've tried different usb ports, different cable with no luck. Yes I have USB debugging checked also. Maye as midimench mentioned above it has something to do with my firmware version of T900UEUAND4. Shortly I'll report back whether the XP solution solved my problem. Any other ideas for those of you who have had success would be appreciated. Thanks!
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] JJMT:
Take a look at this thread.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] sparks305:
BOOM! It worked, wow thanks so much!
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] midimench:
What exactly worked? Did you start with t900ueuand4 and use cf-auto-root-v2wifi-v2wifixx-smt900.tar.md5 to get rooted? Or did you do it another way?
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] sparks305:
First download this: http://xdaforums.com/attachment.php?attachmentid=2591013&d=1392923580 and in download mode with odin flash it. Next reboot into download mode again and flash chainfire's root package make sure its the version 2 one (cf-auto-root-v2wifixx-smt900.tar.md5) with odin, then complete!

Yes my tab pro 12.2 was updated to the latest T900UEUAND4 when I rooted it. The key is to flash the different recovery first then flash chainfire's root package.

So taking it back one update to B5 before doing chain fire

That's a slightly different file
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] sparks305:
Yah probably rolling back to the previous firmware you could avoid having to flash the recovery prior to the root package.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] midimench:
I said B5 but meant B3

---------- Post added at 05:06 PM ---------- Previous post was at 05:04 PM ----------

I forgot to ask earlier. Does this require a complete wipe am I gonna start over?
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] JJMT:
My experience was that I flashed the B3 recovery, then the Chainfires file, and then discovered that wifi worked but would not do secure connections. So I had to wipe data. So yes, you should expect to wipe.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] midimench:
I flashed the file P900XXUANB3-RecoveryImg.tar, when I rebooted I still had the build kot49h.t900ueuand4 installed. I then ran the chainfire auto-root file and everything works like a charm. I didn't even have to do a factory reset. I installed root checker for verification and installed Titanium Backup which asked for root access just like it should.

Hi,

A little question for a newbie that i am.

Do the CF-Auto-Root-v2wifi-v2wifixx-smt900 work with a NB5 version ?

Thank's for your answer.

Best regards.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] midimench:
Don't know the answer to that one, my firmware ended in the letters nd4. After running the recovery file that never changed
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] Return_Of_Jedi:
It's normal that you version number dont change. Cf autoroot allow to install appications who needed the root right.

Thank's for your answer.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] midimench:
Yes. The auto root file was all I needed after running the recovery file. Both are done through Odin 3.07 in this case
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] Return_Of_Jedi:
Hi,

I have seen that you have a SM-N900V.

Mine is a a SM-T900 but this recovery is the same for a Galaxy Pto or Galaxy Tab.

I will patch tommrrow if i have time.

[Galaxy Tab Pro 12.2, 10.1, 8.4 General] midimench:
Don't be confused by the model of my note 3 phone which is SM-N900V (Verizon variant). My tablet is a Tab Pro 12.2 model SM-T900. I use tapatalk on both devices.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] Return_Of_Jedi:
Hi,

Sorry i dont understand that you have both Note 3 and Tab 12.2.

The recovery will be the same for Note 3 and Tab 12.2 ?

ROJ
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] midimench:
Let me clear up the confusion I saw that you had referred to my tablet with my smart phone model that's why I said what I said. I was referring to my samsung tab pro but I was using my phone to make the reply. That made the phone model appear at the end of my text. In the part where it says "sent from my SM-N900V". The recovery for each device is very different, but I have only been referring to the tablet the whole time. My tablet model is SM-T900.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] Return_Of_Jedi:
Thank's midimench,

I have understand and see my mistake. I never heard speak from this spartphone in France, but i dont not all know.

when you patch the root fot SM-T900, i mean that the knox will be on ?

So received my tab pro 12.2 yesterday and spent hours in the loop of odin,install auto root,stuck at cache, recover,rinse and repeat. My next step is to try on a old Winxp netbook...

[Galaxy Tab Pro 12.2, 10.1, 8.4 General] ugabuga:
I'm at a loss guys - still cannot get past the Cache.img.ext4 - i modified the bat file and

flashed the new recovery via odin 3.07 then rebooted. Next shutdown, download mode, Odin and cf auto root yet again and same damn issue.

Current build KOT49H.T900XXUANF1
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] rchtk:
Yes, CF Autoroot WILL trip the knox warranty bit as it installs a custom recovery. This is mentionned on CF Autoroot main page.

The USB interface and protocol for these tablets is indeed a bit tricky. I've had much less problems with my Galaxy S III (for which the odin protocol is supported in linux and mac)

So I've been using a virtualbox guest windows XP in linux host.. not the easiest but after a few trial and errors, I rooted my 10.1 using CFAutoroot.

Play with some combinations: using kies, revert drivers. Close kies, disconnect, start in download, at the warning where you have to push volup: plug, and quickly start odin (been using the one bundled in CFAutoroot zip). Then select PDA, then Start.

Is that a United Kingdom firmware? I'm a bit confused on what firmware I can use. I'm in the US and am on ND4. NF1 is newer, so can I flash any firmware from any country or would this cause problems?
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] k1ng617:
Hey man,

If you are still having issues, I might know why. I was running into the same issue where it wouldn't pass the cache and the screen would go all funky with little dots cascading down my screen. I kept cycling through recovery, reboot, & download modes. After the reboot from the fresh recovery you need to go into the stock recovery and clear he cache then go into download mode to install the new PDA file. After I did that, it worked perfectly!

Just so I am clear, I have a Tab 12.2 wifi, was on the latest ND4 firmware, and updated with CF-Auto-Root-v2wifi-v2wifixx-smt900.tar.md5.

I hope this helps!

Bringing this back from the dead. I have been trying to root my Tab Pro 12.2 with [MENTION=631273]Chainfire[/MENTION] autoroot and it has not been working for me at all. Let me know what information you need from me and I will oblige. When I attempted to root using the package from Chainfire's site, it got to writing the cache part of the MD5 and then hung up. After that, I got a garbled up screen from download mode that looked like rainbow pixels. Anyway, I was able to get my tablet back to stock, but I still want root. Any ideas?TIA
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] JJMT:
Yes, that happens. Please read this thread. You need to flash the recovery from the P900 before you flash the auto-root. You may need to format cache as well.

I was very hopeful that step #3 would get this sorted out as flashing any auto-root would get stuck on flash.img. However it did not work, either with the p900 or t900 auto-root.

It finally worked after and only after flashing TWRP using this guide: http://www.carbontesla.com/2014/08/...-7-recovery-galaxy-tab-pro-12-2-wifi-sm-t900/. Then the t900 auto-root flashed without problems and gave me root. Still had to install SuperSU app manually though.

I confirm that I have successfully rooted my Samsung galaxy tab pro 12.2 KOT49H,T900XXUANI1 has described here.

No more need to use resources prepared for Galaxy note pro model.

- I found USB drivers here.

- I never found "enable USB debugging" option in 4.4.2 stock rom system menu,but worked without that.

- I started odin in administrator mode ( windows 7 64bits)

- first launch of supersu after boot hangs on trying to disable knox. supersu was up to date. disabling knox worked well at 2nd try after an other reboot.

next step : fix writing sdcard problem. That's why I decided to root my device
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] blownupp:

Has anyone had issues with their Tab Pro since rooting? I rooted mine and then it started randomly soft rebooting, especially when left with the screen on after pausing or stopping video playback. It's mostly after the screen turns off or is turned off after playback.

[Galaxy Tab Pro 12.2, 10.1, 8.4 General] Speedstra:
I had the same problem. Found out through this site that it's to do with knox. Superuser disables knox on its first start. I had major random reboots. I solved it by using Titanium backup. In TB one of the Knox apps showed up as frozen. Defrosting it did the trick.

Hope this helps,

Speedstra
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] sksbir:
yep. I have noticed that. get random soft reboot too, even with device left alone since a long time.

I also noticed that sometimes after unlocking, touch screen feature is disabled. I have to lock it again ( power button is still working ), unlock it to get touch feature back.

I must say that after rooting, I have installed avast, activated firewall and disabled network communications for a lots off applications which have no reason to get net access. ( screen savers, side by side and so one ).

I think the best way to solve that ( and a lot's of other inconveniences ) is to install twrp and an alternative rom without knox softwares. Playing around with stock roms doesn't appears to be a good idea from my mind.

Hey Ludespeed,<br />

I used the CF-Auto-Root-v2wifixx-SMT900 to get root. Then I used image file of 2.8.6.1 TWRP for the v2wifixx. (Looks like the 2.8.6.1 version isn't available for the v1awifi version) Then I downloaded "FLASHIFY" from the Play Store and used the "RECOVERY FLASH" in Flashify to flash the TWRP image file.
