[Q] Failed Sprint Note 2 Root Stuck in Loop, Dev not answering

I attempted a root on Samsung Note 2 Sprint version (in white). Followed all steps, however phone got stuck in a reboot loop right after I put the option 2 (root only) Odin step in. Sprint ver LPH889 (I believe that is what Odin is calling it, option 72). Toolkit used was ADB 4.1.0.
Original symptoms were that the Android updater was looping trying to load everything; being new I made it worse and tried recoveries and reloads which also failed. Now it boots, goes to splash, circling blue oval image and...it stays there.
Good news: I have access to download mode and recovery reset mode (including sideloading).
Bad news: every thread I've followed has given me an issue.
I have recovery access but I need some idea of where to go from here and searches have shown near but not exact symptoms. I have unplugged it from the pc, removed the battery, done a factory reset, attempted to reflash via Odin (root) attempted to reflash stock via Odin and so far I am still stuck in a reboot loop. Windows detects the phone but shows a problem in device manager because possibly it won't stop rebooting. Any help you can provide is appreciated and if at all possible I need to recover some form of working phone here, and soon. My girl needs it for work and Sprint's network in my area barely works from day to day (which they admit but don't credit my account for). This phone has problems sending/receiving calls, they claim it's fine, and I was forced to try a root to get some form of working device. That failed too.
I'm a newb at this...it's been years since I flashed a phone (Razor v3), so...any help would be appreciated, otherwise I have to crawl to sprint/samsung and get it replaced, which I don't want to do. Thanks.

What method are you using to root.....I used the "toolkit" and had no problems at all.

I thought it would to but I did not want to dig through 70+ pages of the thread when searching failed...unless I really needed to. Most of it is old and doesn't apply.
I was directed by the referenced Youtube vid. I used the options referenced for the phone in this thread with that toolkit. I backed up existing files (not as one unit, but internal files and I think OS), went for the option 2, followed the instructions and things went great through odin...until android went to update and started looping with the 'updating files' percentages. At that point I tried to restore to basic and started clearing caches and such and that is how I got to where I am.
When that failed I started looking at the leaked stock flash and that failed on shoot.ini which that guy never addressed because he thought his international version was all versions (that's why I choose 'doesitwork?' as screen name ). So i'm down to sideloading or something. I really need guidance, and I emailed the toolkit author but I'm still waiting on a reply.
Any thoughts?

When used the toolkit a year ago, I found that I had to turned off all firewalls and antivirus apps for it to work properly. Once I did that it worked fine....give it a shot...can't hurt......might even be able to repair what you've done so far.....Good Luck!!!

I'll give this my best shot...download a rooted rom from the development section and place it on your SD card.
Download toolkit from here (I take no credit for this) http://d-h.st/iu0
Put phone in download mode.
Open ODIN and uncheck "auto reboot". Then click "PDA" and add the .tar file (recovery).
Plug phone into PC (make sure to have samsung drivers installed).
Once ODIN sees the phone you can click "start".
When the recovery flash is complete, pull your battery to ensure power down.
Boot into recovery : volume up, home, power all at the same time.
Flash rooted rom.

Toolkit is an extra and unnecessary step.

Grab the one click flavor of choice. Use the one with 1090526 in the name as that's the full version.
Open in windows, put phone in download mode and flash. Easy Peasy.
Let me know if you have any issues with this.

Sorry for the late reply, I had some issues with the "catchpa".
The one click fix worked like a charm, thank you! I will soon be making a contrib to the site. It's a shame I couldn't root as easily :laugh: .
I know the level of work that goes into this stuff and the desire to keep on top of new gear while maintaining support for the old and I appreciate the community coming to my aid, so again, thank you!

It is usually a pretty common courtesy to hit the "thanks button" when someone helps you out.
I am not at all trying to be mean, just letting you know.

Digital2 Platinum Pad 8 - D2-861G-BK

So I created this topic because there is hardly anything on the internet regarding this tablet. I just recently purchased it from Best Buy and it took me quite some time to find something that would help me root it. Finally, I tried vroot ( a rooting application) and I succeeded in rooting my tablet. I don't have the exact link I used to get vroot but a simple Google search should suffice. Anyway, I figured I'd start this topic for anyone and everyone who uses this tablet or knows of this tablet to discuss any other developments. For now, if anyone needs help rooting their tablet and getting superuser running, I'm here to help.~
For now, I hope you all can figure out how to use vroot (yes, I know it's in Chinese. I can not read Chinese but it was pretty simple to get through the process of rooting.) Anyway, I don't remember the specifics but if anyone else gets through it, I ask that you please post some details on how you did it for everyone else to get through it as well. Hopefully, with time, we can get some good stuff going with this tablet. Could anyone figure out how to get CWM Recovery running on it? I'm a bit new to this and I don't want to screw anything up.

Thanks for the heads up! I also bought this tablet about a month ago. I was impressed with how thin and light it was, and how nice and bright the (IPS) screen was, especially for a cheaper "no-name" tablet. I've since found virtually no online support for this. D2 didn't even seem to list it on their own website. Although, finally today, I found this thread, and this site: http://www.d2pad.info/index.php?option=com_content&view=frontpage&Itemid=585. Seem the model is exclusive to Best Buy.
The only problem I've had with this tablet is that on rare occasions, if the screen is left on too long, the touch controls go a bit haywire, detecting random touches all over the place, and not really responding. Simply turning the screen off and back on fixes the problem. (Also, the camera is kind of ****ty, but I don't really care about that)
Anyhow, I'll definitely be trying to root this tomorrow. I take it you didn't need any special drivers? I came across this (http://scottyzone.com/2014/03/17/connect-the-d2-961g-to-adb-using-google-usb-drivers/), which I'll try if I can't get the tablet connected to my computer properly to run Vroot.
Thanks!

Thank you for bringing some needed attention to this topic! I actually used the Vroot application, rather than the software. It took a few tries but I got it to work. If you want to try the software, however, I've connected it to my computer numerous times without the need for any special drivers. Only thing I can suggest is the generic google drivers. By the way, I reverse searched the tablet's hardware and kernel and came across a duplicate device from China. It is exactly identical right down to the appearance, hardware and software to our tablet. It is called the Chuwi VX8 and the only difference is that it comes in white rather than black.
After making this discovery I came across a nice little development topic for the clone device (http://www.freaktab.com/showthread.php?16025-Chuwi-VX8-RileyROM-1-1) and it seems they've founded good amount of research into the tablet. They've come up with a rom (I've yet to test), CWM Recovery (Unable to flash. If anyone else can try, that'd be dandy.), root methods (with links), among other things. It seems that anything that would work with the Chuwi tablet SHOULD work with the Digital2 Platinum Pad 8. The same rooting method was required and everything about the two tablets is perfectly identical so I'm led to believe they're going to be able to use identical roms or recoveries. I'll look more into flashing CWM Recovery tonight and get back to you on my results.

Which app exactly are you referring to. I thought it was something in the Play Store, but no luck finding what you're referring to.

Found this link (http://products.mgyun.com/api/downjump?id=846) just for you. It should work but let me now whether or not it does. It's the exe for computers but if it doesn't work Google "vroot apk" for the app.

As you mentioned, the link was for the (Windows) software. It requires ADB connection to a computer (usually requires special drivers).
When you said you used the application instead of the software, I assumed you used an APK. However, there is no apk of (the official) Vroot (it was designed to work through Windows). That makes me think the root app you used was something else. So I have to ask... what did you use to root this device?

vRoot is now iRoot
First off, I'd like to thank you for starting this topic. I've searched all over since I bought this tablet a couple of months ago but couldn't find any information. When I did a google search for vroot, i found http://www.mgyun.com/en/getvroot and the software is now called iRoot, and is in english. The main link on the page is for the windows ADB version, and there's a link further down the page for "iRoot for Mobile", which will give you the APK. Now that I've got root, I'll keep trying to get CWM recovery to work, and maybe we can start seeing some ROMs come out for this great device!
UPDATE: (IMPORTANT, please read): The APK does not work. or at least, I couldn't get it to work on my device. It tells you that you've got root, but doesn't really give it to you. Download the computer based exe from the link that Josh8550 posted earlier.
You will need developer permissions (Settings -> About Tablet -> tap Build Number until it tells you you're a developer).
Install ADB and Drivers on windows PC (http://forum.xda-developers.com/showthread.php?t=2588979)
Connect tablet to PC with USB cable.
Run vRoot (iRoot) on PC. Program will connect to tablet and check for root.
Click the "Get Root" button.
Wait...
Tablet will reboot.
Wait...
Program will connect to tablet and check for root.
Program should verify that you have root.
Download and Install SuperSU from the Play Store.
Open SuperSU and Update SU Binary. You will have to give SuperSU root permissions from the chinese interface (choose the box on the right, don't mark the check box).
Reboot.
Congratulations! You now have root access. Enjoy!
More info to come later...

Thanks man. I couldn't find the link to the apk again so that's a huge help for everyone here. I'll try to get CWM recovery working soon then I'll see about getting Cyanogenmod 11 ported over.

Rooting Digital 2 tablets
Hey everyone.
I successfully rooted with Kingo ROOT using my PC, however now Im stuck. Cant seem to find ROMs or Mods compatible with this tablet.
Any info out there would be great. Im running a 4.1.1 Jelly Bean.

Rooted now what?
Did you ever try the cwmr or cyanogen ROM you had mentioned above?

I did, and ended up hard bricking it for months until I finally got it back out, fixed it and gave up.

I also have the D2-861G and ended up bricking it but have been unable to fix it, would you mind telling me how you got it back up and running.

Phone Inadvertently Upgraded to 4.6.4. Is downgrade to 4.6.1 via ADB Safe?

I just received two phones (from the excellent eBay deal that I'm sure will drive more popularity of this forum), and stupidly, while working on the first one (getting CM11 on which went seamlessly), I forgot to disable updates on the 2nd. When I turned to the 2nd phone, my heart sank as I saw that it was now on 4.6.4 (464000220). My immediate thought was to boot into recovery and sideload 4.6.1 (820) but I remember reading that there is danger in downgrading this way?
Can anyone shed some light if downgrading this was is safe, or if I am no royally screwed? While Kingroot has no problem rooting 4.6.4, I'm trying to get to CM11 so I need Safestrap which apparently require 4.6.1 (820).
Any advice would be much appreciated!
Thanks a bunch!

I received Fire Phone today from the eBay deal..
I was reading thru Forums before i connect to Wifi.
Could you please share how you disable updates?

So in the absence of any response, I decided to just do it, and can confirm that sideloading 4.6.1. after having updated to 4.6.4 is without any ill effects. What a relief. As the eBay deal has about 7000 purchases, I'm sure others will fall into the same hole, so I hope this is of help. I used used Minimal ADB to serve as the deskop-side bridge (largely because I already had it installed from when I flashed my HTC One M8).
I must say the flexibility and simplicity of flashing these fire phones is even better than with HTC Ones. Ability to sideload a ROM baked into stock recovery is fantastic. If only all manufacturers were as (perhaps unintentionally) flash friendly.

It's surprisingly easy. Simply go to Settings (the Gear Wheel in the menu), then on over to Manage Applications (I can't remember exactly what it says as I've flashed both my phones over). In this section, make sure to select the filter at the top to list All applications (I think it defaults to those "Downloaded"). Then simply scroll to two entries that say System Updates. Select each and select Disable. That's it!
As I mentioned, if you are looking to flash CyanogenMod (and you really should since FireOS is extremely clumsy and poorly thought out), this doesn't matter as you wiping the phone of FireOS when you do so. The good thing is that if you don't like CM, you can always flash back to FireOS per the flashable images provided in other threads here.
Hope this helps.

hey there...
can you post a link to 4.6.1?? thanks..

Just a heads up, my phone is an unlocked model on t-mobile and it OTA updated while I was in the store to 4.6.4. and rebooted into recovery with an error message. Only operation is to sideload. Will absolutely shut that **** off when I'm done.

I am on 4.6.1 and I disabled the 2 system updates app.
but still, its trying to download 4.6.4 update.
any idea..
How do you ADB fire phone.. I couldn't get ADB to work. I may miss drivers though.

I believe there is a third system file "DCP" that needs to be disabled. The list of apps adjusts in a couple threads here.
I would install a package called "Minimal ADB and Fastboot" which you can find on a Google search. A small and effective installation that works well.

No OS will install properly, odin won't work, need help with TWRP on N5110

This is my first post, so please forgive any mistakes I make with a post.
My wife's Galaxy Note 8.0 tablet was being stupid, it would refuse to properly use the internet from our Asus router, would connect but apps would insist there was no connection. Was getting tired of that crap so I decided to install a custom ROM, since samsung can be kind of jackasses abandoning most their devices after one major update, was only running Kitkat for crying out loud. I had done so before, but issues arouse. For one, I had great difficulty finding a proper TWRP for some stupid reason, NO ONE seamed to know where to get a well working version. I found one, but it messed everything up, it seems to work just fine but any ROM I install has massive issues with the Google apps, they crash eternally and continuously so I can do literally nothing, can't even get past first setup. I came across talk that it was old TWRP to blame, that it has issues with newer OS's like the lollipop I was trying to install, and FINALLY managed to find a newer version of TWRP, but freaking Odin keeps hanging on it's install, gets to "Nand write start" then stops doing anything. I have tried different cables as well as different computers, does jack crap so far to help. My backup I made in TWRP doesn't even work, when I restore the result is nothing but a boot loop. I am trying to find a stock os to restore it to (mostly) original condition, but it is absurdly difficult for some stupid reason to find, found one all in one exe that didn't work for a damn. I was hoping there might even be a way to install the newer TWRP from with TWRP itself. Can anyone help me with any part of this?

First things first. Calm down.
Do you have Samsung Smart Switch installed on your pc? If not, do so.
Connect your note 8.0 to your pc, select the 'more' button and then Emergency software recovery and initialization. Let that run is course. It can take a while.
See if that helps.

Sorry, but you are going to have to be a little more specific. I installed Switch, but connecting an off device obviously does nothing, should I install and let it boot into a broken ROM again, where gapps crashes, and connect it then?

If your main isues are with GApps try clearing the cache in the play store app, check the date and time on your device.
I literally just got my Note 8 up and running after suffering these same issues you describe. My thread on this:
http://forum.xda-developers.com/galaxy-note-8-0/help/note-8-0-stuck-screen-t3218608
I'll try my best to help you. I received some good advice and I 'd like to help someone as a show of appreciation.
We'll get this straight!

Thanks, pretty much.

None of what you said really made sense, I could not get to ANYTHING AT ALL that was not Odin or TWRP. But that link you had gave me the name for the stock os, I searched that and flashed it and now everything is great. So thanks, sort of. You even mentioned that method not working for you I think in that thread, but it did for me, so yeah.

All good then.

Trying to get a clean install on a crippled SM-T540 (Galaxy Tab Active Pro).

Edit 3: USIC, after further investigation, has confirmed the tablet was actually one lost in shipment and compensated for by insurance, the sale was legitimate (not a stolen device) and they unenrolled it from KNOX before I could ask if they would do so. So, overall a satisfactory outcome, even if the tech part of me wanted to find a way to defeat a technical challenge.
EDIT 2: The device may not be stolen after all, seller has given a plausible explanation. Withholding further judgement until more information comes in.
EDIT: I was originally thinking of 'USIC' as a subsystem of Android or KNOX. A user on Reddit suggested I reach out to the company USIC and see if the tablet was stolen from them. I did. It was. Will be getting the tablet back into their hands and pursuing a refund from the eBay seller. Will leave this post up in case anyone has a use for the technical rabbit hole I went down.
Backstory: Found a good deal on a new Galaxy Tab Active Pro from an IT liquidator company on eBay, it was listed as locked and price reduced because of that. I thought along the lines of 'hardware access is total access' and figured I would be able to wipe / reset it.
Device arrived today, the crippleware (MDM or administration software actually, but I'm feeling ornery at it) installed is Soti Mobicontrol. I can boot into the OS but a bunch of stuff is disabled. First I initiated a factory reset from Settings - it resets and during setup lists "This tablet is protected by Knox Cloud Service. To continue setup, connect to a Wi-Fi or mobile network." From there it states "Your admin can monitor and manage settings".... a bunch of stuff ending with "USIC will manage and monitor this device using the following app: MobiControl" with the only option being 'Accept & continue'.
Tried another factory reset through the boot menu (hold down vol down and power to reboot followed by hold down vol up) - same result.
Found and downloaded the same version firmware the tablet currently has: SM-T540_XAR_T540XXU2BTG5_fac.zip where XAR appears to be the US/Canada region code and T540XXU2BTG5 is the exact version of firmware the tablet currently has installed (verified by going to 'Software information' in settings).
Downloaded latest version of Odin (3.13), booted the tablet into the correct mode and flashed clean firmware (just the AP firmware) to the device. Went through first install sequence to no change in behavior, still installs Soti Mobicontrol as a device admin.
I've looked into maybe getting TWRP installed (so I can delete KNOX from TWRP file browser perhaps as demonstrated here:
) but as far as I can tell there isn't a build for this version of the tablet - closest I can get is for the SM-T547 XDA forum post on it here: https://forum.xda-developers.com/t/...alaxy-tab-active-pro-10-1-snapdragon.4284347/. Also not sure how I would get it installed since I can't enter dev options in the tablet (tapping on Build number, even in safe mode, results in a popup: Action not allowed This action is disabled by MobiControl.

I've found someone on YouTube (
) who removed the software just by intentionally entering a wrong password until a factory reset tripped - but I am already able to use the factory reset option and the software comes back. I'm thinking Soti Mobicontrol and the KNOX service are separate issues and in this person's example he was only dealing with Soti and not KNOX Enrollment.
Next I found this gentleman on Youtube:
who specifically mentions using the 'Nand erase' option in Odin along with flashing all files in the stock firmware to remove management software. Tried that, no luck. Same as each install I get the message 'Updating... Updating Knox Enrollment Service... X%' after being required to connect to wifi to continue setup with the 'Skip' option greyed out.
So, that's where I am right now with it, and I refuse to give up. Ideas?

@studentoflife don't know this device but might be a chance to flash the multiple part stock ROM you can get via Samfirm_reborn.

I am unfamiliar with Samfirm_reborn. What is this project? I can't seem to find much in the way of descriptive notes.
Edit: apologies, did some googling and now know what Samfirm_reborn is. I'm pretty sure I've already flashed all parts of the stock ROM - downloaded the T540XXU2BTG5 version firmware and flashed the BL, AP and CSC images. No CP image given this version of the device does not have a cellular modem.
Hm. I suddenly wonder what will happen if I reflash with the earliest version instead of the current one. I know I don't want to update it to the latest firmware in case that applies some security patch that can't be downgraded and locks out some workaround I haven't found yet, but downgrading... maybe.

I have a similar tablet with mobicontrol. I can't unlock OEM so all the methods of flashing new firmware I tried, failed. Have you had any luck since your last post?
