Hello! So after some research in the forum, and seeing that it can be "easy" to root your phone, even with a locked bootloader, I decided to look into doing this with my Verizon Galaxy Note II to get familiar with custom ROMs. I had been running on 4.1.2
Please redirect me to relevant forum information for DIY or feel free to contribute any help below. Also, feel free to shame me for not finding it myself, as I couldn't find it myself.
I used "NoYouVerizon-GalaxyNote2-Casual R515" to root my phone and about 5-10 seconds through the installation it errored out and showed "Disconnected". It stated that I needed the relevant drivers from Adam Outlet which I accepted to download, but I did not re-recognize my phone afterwards while in the download screen. But, since it error, I get the incompatible firmware yellow triangle of frustration. I can't seem to use any software such as Odin, most likely because my bootloader is still locked?, so I'm going to ask you experts for help while I research a way to get it out of this mode.
Edit: Also, I have the issue where Odin states "Can't open the serial(COM) port" which causes a failure. Attempted to flash root66_VZW_Stock_etc
Edit2: Was a Samsung Kies issue. Uninstalled and able to start root66 on Odin. Processing now
Edit3: Was able to wipe/reboot in recovery mode to get back to stock. Now I'm curious of why Casual had the error. Any suggestions from the error file uploaded?
Edit 4: I have my phone back up and working with root access. Though I'm unsure how I have root access without doing much to unlock the bootloader from verizon, I guess this works. Any commentary welcome.
Any help would sincerely, 100% be appreciated!
Hi all,
I recently got a new Dell Venue 7 3740 (yeah, not my first choice, but it was free for buying a computer). Anyway, started reading up on how to root the thing. I have a couple of apps that require root.
I found this thread: http://forum.xda-developers.com/dell-venue/development/guide-how-to-root-android-4-4-4-dell-t2918427
and also the main Dell page: http://opensource.dell.com/releases/Venue_7_3740_Merrifield/developer-edition/
Following Dell's guide to rooting appears to NOT root it. Installing Root Checker confirms I don't have root. Unbricked it and got it back up from 4.4.2 to 4.4.4. By reading the first guide for the 3840, my question is ...
Is the boot image linked there compatible with my 3740?
(yeah, I know this should be in the developer section ... unfortunately I don't have enough posts ... also, I am familiar with rooting/flashing/etc, my first device that I put CM7 on was the original Galaxy S1 ... and I have CM10 on my S3.)
Tried, failed
Yeah I got this tablet with a PC too and tried rooting. It FUBAR'd on me and I had to wrestle with unbricking it. Which sorry to say is a job and a half, the images on Dell's site are corrupt for this WiFi only version (no partition.tbl file, system image incomplete). Ending up downloading the LTE versions firmware to get the missing files and rewriting the batch as the file names for the fastboot commands were wrong too. And even then the tablet wouldn't boot, so I had to store the OTA on an SD card and use recovery to flash it. Unfortunately that leaves me with 4.4.2 and the dreaded clock and browser issues. And OTA doesn't work, it keeps saying no updates are available. Spoke with a Dell rep who said OTAs were suspended and to try again in a week but I think OTA was broken for me when I tried rooting and boot loader was unlocked (which the PDF on Dell's site warns you about).
So now I have a working tablet that skips hours ahead and has general stability issues.

Hmm ... Interestingly enough, I ran through the unbrick procedure from Dell, and didn't have any issues with it whatsoever. I'm not sure if they updated the TGZ since you updated.
I have read that root is for ADB to start with. Can anyone confirm this? If so, then which package could I get for a superuser binary?

I did this process just a couple days ago so everything I pulled from opensource.dell was current. The unbrick tgz on the site shows up as 128mb for the wifi only A1195 and the A5195 shows as 821mb (odd). When I extracted the tgz it said "unexpected end" or something like that on the system image. Then again when I extracted from that extracted tgz.
Following the root process initially worked and the temp cwm recovery let me flash the supersu update. It booted with su just fine and I tried a couple apps that needed root and they worked. Once I rebooted again the tablet showed up with a USB icon and would go no further. Never having dealt with Intel SoC drivers it took me a while to get them installed properly, and then I eventually understood what "full power off" meant lol.
Do you know how I can relock the bootloader and get OTA working again, assuming I'm already on 4.4.2 from the OTA zip installed via recovery?
Thanks.

You better redo the unbrick procces cause as you are now, you won't be able to update your tablet and 4.4.2 has some issues with the clock and browser. The best way to root is by thetered cwm, I did it and it's working great.

This is quite odd. From the documentation, it appears that the A195 is for the LTE version, and the A150 is Wifi only. Since I have the 3740 Wifi only, I only pulled the A150 version.
The Unbricking process was very straightforward and everything went smoothly, and after it rebooted, it prompted that there was a system update from Dell, and that took me from the 4.4.2 from the TGZ, to 4.4.4

* For Wifi-only device on A150 and Wifi / LTE device on A195
I see it now, I think I was misinterpreting the above statement which means I've been flashing the A195 rom this whole time. Thank you all for your help! :good:
After getting my 3740 back to "Unbricked" mode, and OTA upgraded to 4.4.4, it appears that I'm completely locked out of the rooting process.
I've tried to start over with the Dell info (unlocking bootloader), however, neither of my PC's will detect the tablet when using xFSTK (one PC - Win8.1-64bit, other XP-32bit). The tablet IS detected, however, it appears that the drivers are no longer correct(?).
I normally run Ubuntu, and thats where my Android development setup is on ... I see that xFSTK is available for Linux ... has anyone used it? or would I be better trying to fight Windows?

It is mentioned somewhere that the 3740 and the 3840 use the same firmware. Assuming that, what you can do is download the latest SuperUser zip, copy it to the internal or external storage, then use THIS, or THIS to root through CWM.

Hmmm ... I took this to mean that I could use the same boot.img as the Venue 8, and tried the process from this thread: http://forum.xda-developers.com/dell-venue/development/guide-how-to-root-android-4-4-4-dell-t2918427
NOPE. (Don't try, it'll cause the tablet to go into the "help my androids' fallen and can't get up" icon. )

I'm curious as to what it is you're trying to do. Why do you insist on having a developer's root (just the use of ADB shell), as opposed to full root flashing SuperSu from custom recovery?

I just want full root.
Most of the info that I've read on here and elsewhere are geared to the 3830/3840. Not as much for the 3740. So, by playing with the device and learning what works/doesn't work, possibly others may find this info useful to them.
I've been having issues seeing the device from XP, Win8.1 and Ubuntu, in the 'off' state of the tablet, when the PC should be seeing the merrifield. Just this morning, after bricking it last night, I discovered that my PC seems to see the device right away if I press Vol+ while plugging in the microUSB. (again, something that may help someone else) I was planning on double checking this info later today, to make sure that it wasn't a fluke.
I do appreciate both of the links that you've posted in this thread, and I will check them out. Of course, both are labelled for the Venue 8, not the Venue 7 that I have. Since I've gained knowledge on the unbrick process I feel more comfortable trying them.
I've installed (or tried to install) SuperSU from the Play store, but it didn't appear to help much, since I didn't have the custom recovery setup at that time. I'll work on that tonight.

A quick word on getting the device recognized in off mode, what worked for me was it needs to be completely powered off and nothing showing on the tablet screen then connect and bring up the device manager. Whatever shows up needs to be "Intel SoC" so change the driver to that if needed. When flashing firmware to unlock the bootloader the device's boot screen will show an "Intel Inside" logo instead of the normal "Dell" logo. I ended up running xFSTK commands in advance (they'll wait) and then running over to hook up the tablet (powered off) via USB as for some reason it'll show up and then I hear "da-Dunk" in Windows (device disconnected) after a short while which interrupts the process (same with fastboot commands). This was the unbrick process in a nutshell for me and I'm leaving it now as is (OTA'd to 4.4.4) until hopefully the supposed update to Lollipop comes around and maybe some progress is made on rooting it.
Hope this helps you!

I have finally settled down and got the tablet rooted. What's really odd, was Win8.1 kept losing the proper driver. I'm not sure exactly why ... but suffice it to say, I got it working. It did appear to be more stable when I hit the Vol+ and plugged in the USB, but then again it may have been a coincidence.
Open source dell
If you follow the link to dell open source, they do have a detailed PDF download for unlocking the boot loader etc. The file was too large for me to upload on XDA. I just found it today while I was researching how to root this tablet. I have not had a chance to try it yet.
http://opensource.dell.com/
That doesnt work for 3740 lte. I;ve done everything that was in PDF. OTA image should be with unlocker bootloader and root but its not. ;/
Its adb root not su big difference
Does anyone have any idea to root dell venue 7 3740 lte
The open source is for venue 7 3740 wifi

This is a zip file with all the tools and files you need and instructions on how to use them.
What it covers:
Restoring bricked device (as long as download mode still works)
Unlocking bootloader (firmware dependent)
Rooting (any firmware)
Installing a custom recovery (any firmware)
Installing a custom ROM (any firmware)
I made this because all the guides for this phone were seemingly outdated, and some required tools and files were incredibly hard to find. Didn't want anyone else going through the pain I went through to break this phone open.
Thank you so much for uploading this. The charging port on my Nexus died and I have to use my old Note 2 as a backup, but I forget how this old piece of junk works. This should be very helpful.
I rooted and flashed twrp to boot to a triangle saying system software not authorized. Tried 3 firmwares and wont boot correctly. I got error about firmware update failed use kies... Kies won't do anything and kies 3 says unsupported device. On the 3rd firmware (root66 rooted stock ) firmware file I now am back to the original triangle system software not authorized by Verizon ..
How do I fix this?!?

Did you read my guide? You can't flash TWRP unless you successfully unlocked your bootloader with Casual, otherwise you are limited to SafeStrap. Also you can't restore with Kies, you have to use Odin and the files I've included to restore.

Nice to see people still looking for something like this, so my guide wasn't for nothing!
I was geeked to see this!! but then i got "This item might not exist or is no longer available"
I take it back.. i let it sit on the "failed" page for like 2 min, and randomly it popped up with a download!
Well the auto bootloader didn't work, so now i'm at the root section. However i'm getting an error where ADB isn't detecting my phone. USB debug is on, and i'm definitely in media mode and not installer. The phone shows up in windows and looks good, but adb doesnt detect. I opened command prompt and ran adb /? and found adb devices -l, and it reports "list of devices" and theres nothing in the list. I can't imagine why it's not seeing it. I tried turning on and off debug mode, switching from camera mode to media, changing usb ports. still nothing comes up, but windows sees it fine. grrrr
*edit, well since we can't delete posts i'll leave this here, because i have to. But what i did was re-open the "no you verizon" and it showed DISCONNECTED also. I changed usb ports like 3 times, turned usb debug on and off, changed from installer mode, to camera, to media mode, restarted the phone and the computer multiple times.. and then it just all of a sudden was detected again. So i went with it and it seems to have worked.
-it took 3 times to actually work, you noted it may take multiples, and it sure did. I ran it through the command prompt so i could read the text, and it took 5 times longer and reported much more stuff when it actually worked.
-final edit: if you can't unlock your bootloader, you're still stuck with ditto or alliance from 2014, and lots of apps won't update on android that old. So if you thought this guide was some holy grail, it is not. But still useful if you need the assist, so thanks to the author.
Hi, total noob here, I just bought Verizon note 2 at a yard sale but there is a pin I don't know. When I went to do a factory reset it booted into TWRP, so I am assuming is rooted. Do I need to be able to get into the phone to use your tools? I know nothing about TWRP. I would like to install a newer Android version and unlock it so I can use TMobile. Thanks
Something wrong...
when i try to load this file from the packages folder i get an error message:
"md5 error! Binary is invalid"
none of the other three works for me. they all come back ailed.
any suggestions?
awesome! thanks for posting this, just found my old note 2 and want to get it up and running again for the kids.
Kudos!
Used this to get my Note 2 up and going again temporarily until the Pixel 4a release...
NOTE: I had strange issues with Odin on my modern X570 board (USB 3.2 Gen 2) where I did not receive any errors, yet the process would randomly seem to time out. Sometimes I'd get stuck at flashing boot.img, sometimes it would hang up at the start, once I got to flashing system.img and it seemed to hang....
Used an older PC circa 2013, no issues! Not the first time I've had issues with this newer motherboard and older USB flashing interfaces; had the same issue on my Note 8 (RIP) as well.
excited to try this.
I'm on some rooted 4.4.2 stock-looking rom. Recovery doesn't look custom.
Hoping to be able to install a working Oreo or Pie ROM
great post, bought a couple of these for almost nothing and am having fun playing with them. sadly they are both 4.4.2 but its great fun anyway.
