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

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
how can i hard reset this device please tell me.

Hi there,
I created this guide not so much as a substitute for the other guides or because this would be the best way to do it.
When I looked into rooting my new Axon 7 (international) I studied all the other guides first, but then did it very differently, mainly
because
- I am on Win 7 32-bit and some of the tools used in the other guides don't work for that
- since the other guides were created the Axon7Toolkit came along - that simplified a lot of steps.
The guide is actually very similar to this one for the 2017U:
https://forum.xda-developers.com/axon-7/how-to/complete-guide-to-unlocking-installing-t3561128
Only now with the toolkit it pretty much works for the 2017G as well without the need for tenfar's TWRP (see comments). In case I left out anything, this guide will be of help, too.
So this guide is for you if
- You want to root or flash a custom rom and don't mind unlocking the bootloader OR
- You are on Win32 and cannot use the axon7tool command line tool OR
- You want to use the Axon 7 Toolkit for the job to keep things simple
Please read all the notes below before attempting anything...
Disclaimer
- This worked well for me - no claims it does for anyone else. For the record: I was on Stock 6.0 MM B08 A2017G, no fingerprint/lock etc and went straight to RR.
- Use at your own risk, if you are unsure what you are doing stay stock - I'm not responsible for bricked devices, dead SD cards, Donald Trump, or you getting fired because the alarm app failed...
Regarding Drivers
- Qualcomm ones for MiFlash (link below)
- QUSB_BULK if going with eg the axon7tool commandline version (edl mode)
- You can use the Toolkit to install (some of) the needed drivers
- ZTE drivers - phone is set up to install them upon connect to the PC. Don't.
- Uninstall incorrect drivers, just installing the correct ones won't necessarily do the trick.
MiFlash
- right click & 'run as admin' (flashing didn't work for me without this)
- Correct driver: Qualcomm HS-USB QDLoader 9008 when in edl (check with device manager open)
Boot modes
- power phone down and boot into
- EDL by holding Volume UP/DOWN & POWER simultaneously
- recovery/TWRP (once installed) by holding Volume UP & POWER simultaneously
- fastboot: Not enabled in A2017G Stock
Windows
- 32-bit: MiFlash needed, commandline axon7tool not working
- The toolkit seems to run on Mac/Linux using a Windows emulator/virtual machine (not tested, Wine helps I guess)
TWRP
- versions: Signed tenfar TWRP 3.0.2 that is used in a lot of other guides is buggy and can do a lot of harm - not needed if you unlock
the bootloader first. You can (and should) use the latest official TWRP version.
- dm-verity: https://twrp.me/devices/zteaxon7.html
- USB OTG: Axon 7 supports this, so does TWRP - no need for SD cards. Simply use a thumbdrive with a OTG cable (with included Adapter if needed), boot into TWRP (thumbdrive needs to be connected beforehand) and click 'Mount' in TWRP, then select USB storage
Bootloader
- Afaik DO NOT lock again with custom rom installed or rooted (brick)
Root/Unlock
- Can create problems with Android Pay, playstore etc - see https://www.xda-developers.com/tag/safetynet/
- Root disabled by default in Lineage, needs flashing Magisk or SU - see other guides
- Some features root provides on Android 6.0 MM won't work in Nougat (so far anyway, eg xposed)

Thanks
bkores (for the tool), dnlilas (help in the forum), DrakenFX, Unjustified Dev, Controllerboy & all the guide/rom creators etc in this forum. (And the poor souls who came first and discovered all the ways not to do it, preventing my fall)
1) Prep
- Note down IMEI(s) from your settings/about phone/status/... just in case
- Unlock developer options (Phone settings > "About Phone" > Click "Build Number" 7 times...)
- Check "Allow OEM unlock" and "USB Debugging" there
- Connect your Axon 7 to your PC with the original USB cable - do not disconnect with MiFlash/Toolkit running.
- Open device manager to check your drivers (will show up differently depending on the boot mode)
- Run Axon7Toolkit
- Select Option 1 - Install/Test Drivers
2) Unlock
- This will RESET your device, did you save your data? (using Toolkit etc)
- Select option 6-unlock on toolkit main screen -
- MiFlash launches and one has to select the folder with the files to flash, following the instructions of the toolkit
- Check Device Manager lists your Axon 7 as Qualcomm HS-USB QDLoader 9008, if not uninstall wrong drivers and install Qualcomm ones
- The unlock files the Axon7Toolkit offers are in a folder 'A2017U_FASTBOOT_UNLOCK_EDL' - works for A2017G
(- Axon7Toolkit preview version offers different folder content to flash - have not checked that)
- One can restart MiFlash (e.g. to 'run as Admin') anytime and try again, but after the flash was succesful, do not disconnect the phone but
- Finish off with the Toolkit 'press a key to continue' (or one will have only fastboot enabled)
- A message will appear on the phone: Confirm that you want to unlock the bootloader (using volume & power buttons to navigate)
- Done. From now on you will get an annoying message on booting the phone about your device being unlocked. Just ignore and wait for a re-boot...
3) TWRP
- Unlock developer options - AGAIN etc as device was reset. And - again - enable debugging...
- In the toolkit (main screen) go to '11 Advanced Options', select <Flash boot/bootloader/modem/recovery<choose recovery partition
- In 'Open' dialog select C:\Axon7Development\Axon7Toolkit\twrp\twrp-3.1.0-ailsa_ii.img (or newer version)
- Flash as 'recovery'
- Reboot, check system boots up fine
4) Flash Custom Rom etc.
- Generally: Follow instructions provided with the custom rom you are going to flash (as they might differ)
- Boot into recovery/TWRP (Volume UP + Power after shutdown)
- No need to swipe to 'Allow system modification' - this can actually brick things...see https://forum.xda-developers.com/axon-7/help/a2017u-stuck-zte-screen-boot-factory-t3584062
- Mount/Select storage (for OTG USB)
- Backup boot, recovery, data(if needed), HLOS, System image or System (image was recommended but that did not work in my case, so I backed up system)
- Wipe/Format
- ***If you like to avoid your data partition to be encrypted, follow that thread: ( format your data partition to ext4 instead of f2fs (wipe -> advanced)????)
- Install Bootloader & then modem (or Nougat won't install if coming from MM) - A2017X_B15_Universal_Bootloader.zip & A2017G_N_Modem.zip
- Rom & Magisk/SuperSU
- GAPPS (version)
- Re-boot: Unlocked message, long first time boot - After RR, my phone show up as 2017U... well, who cares...
Any comments to correct errors in this guide or fill out any blanks are highly appreciated...
I dunno why now one has thanked this yet, it is a well written guide imo and useful for those not yet unlocked.
THANKS SOO MUCH FOR THIS!! The timing could not have been any better. I literally just bought this phone from a guy on craigslist for $270 (Couldn't pass that up coming from an LG G4) less than a hour ago. Quick question. It's a 2017u with build B25. Will the toolkit work with it. I don't see an option for this build
Hi Senny,
thanks a lot - I hope the guide is helpful, as mentioned it worked for me. Hopefully I included at least most of the pitfalls one could encounter...
Hi raphi809,
The toolkit should work fine with the 2017U (it should detect your version).
To be sure, also have a look at the toolkit thread (https://forum.xda-developers.com/axon-7/development/tool-axon7toolkit-t3573108) and the thread linked above (https://forum.xda-developers.com/axon-7/how-to/complete-guide-to-unlocking-installing-t3561128), as it is more specific for the 2017U.
The main thing I am not 100% sure with the 2017U is (as I am on a 2017G and started from Android 6.0 MM), if you have to downgrade from Nougat/certain versions before unlocking etc.
If someone could shed some light on this, that would be great!

Hi Whoooo?, first thank your for your time to write this guide.
I tested your procedure and I remain stuck at the same point than the others guides. After Axon7Tool / 6-Bootloader Unlock, MiFlash.exe doesn't launch because I am not under 64bits system. So, after a successful Xiao MiFlash package, I launch it manually (admin rights): my device (in edl mode) is not seen, whatever the driver used (Qualcomm, QUSB...).
If I understand correctly the right procedure to install LineageOS 14.1 & TWRP, Axon 7 must be unlocked in its bootloader by flashing A2017U_FASTBOOT_UNLOCK_EDL?

Hi Volumetrik,
For me the MiFlash version that came with the Toolkit originally didn't work either (as Win32, too).
Instead I used the installer that came with the beta version of the toolkit (v1.2 - there was an installer in the MiFlash folder).
The installer created two applications (MiPhone and MiFlash or similar) - one of them worked for me if run as admin.
Also make sure the right driver is actually used by windows (by checking what is used in the device manager when the phone is connected in edl mode) - Windows is sometimes funny if more than one driver is installed...
Hope that helps

Hi Whoooo?
Thank you for swift reply. In fact, I decided to work under x64 environment, so I made a fresh install. Then, I combined your guide with the others in this part in the forum.
I must say I thank you so much, for your work. For a N00b, it's difficult to sort the main steps to complete the process... even if I already did this on different devices before.
I'll explain in the LineageOS thread how I completed this conversion from a full stock A2017G B03 (MM). It's slightly similar with yours.
Once again, Thank you. :good:
It's now a few days ago since this guide has been published and I wonder why nobody seems to share any experiences. Has nobody tried to follow these steps so far? I am interested whether it is possible to start from Nougat or is MM recommended?

Hi there,
Obviously I have not tried this myself, so I only can refer to these two posts from the Toolkit thread:
https://forum.xda-developers.com/ax...on7toolkit-t3573108/post71673370#post71673370
https://forum.xda-developers.com/ax...on7toolkit-t3573108/post71861250#post71861250
...stating that 'Bootloader mode is disabled in G variant with Nougat update' and one has to either
- revert to MM or
- flash a different Unlock package with MiFlash (linked in the second post)
(There is also a note in the instructions saying that the toolkit's Bootloader unlock with MiFlashdoes not work on A2017U B25)

Hi Marcus,
I tried to find some time to reply and explain how I used this guide and two others to get my device unlocked, twrp'ed and LineageOS. It's running like a charm.
I started with a A2017G device basis with MM B03. My device was updated to the latest official update available via MyFavor network. I didn't try to update OTA.
I Used Axon7ToolKit v1.1.1 + Update_Install.bat / Qualcomm Drivers / A2017U_Bootloader_EDL. I worked under windows x64, because I experienced too many troubles to get Axon7toolkit working properly under 32bits. The only one differences I experienced and not written in the threads:
- I saw a FTM mode (Factory Test Mode) displayed in a white square centered on the device screen after unlocking bootloader. In my memory, it disappeared after TWRP flash.
- I got a problem with Flashlight, didn't work, associated with a problem to call (sms working). I flashed the modem firmware once again, it solved the problem after reboot.
- At the end, LineageOS installed, LineageOS updater strangely saw the same update version installed on the device. The only difference was the"signed" at the end of the update name I launched the update and installed it succesfully, without issue. No more update after that (until a new one of course)
Hope this will help someones

Hi Whoooo?
Thank you for swift reply. In fact, I decided to work under x64 environment, so I made a fresh install. Then, I combined your guide with the others in this part in the forum.
I must say I thank you so much, for your work. For a N00b, it's difficult to sort the main steps to complete the process... even if I already did this on different devices before.
I'll explain in the LineageOS thread how I completed this conversion from a full stock A2017G B03 (MM). It's slightly similar with yours.
Once again, Thank you. :good:

Hi, when are you planning to release your complete guide? This would really help me.
I am trying unlocking the bootloader on B11
When I try flashing bootloader unlock in MiFlash it says:
Lenght cannot be less than zero.
Parameter name: lenght
Tried restarting MiFlash, installing it again and restarting PC. Does anyone know what am I doing wrong?
EDIT: Managed to unlock using Controllerboy guide that didn't work for me at first (why I used toolkit). But I am still curious why that error in MiFlash happened...
Bootloader is unlocked. Drivers are okay, toolkit recognises the phone connected. But every time I try to flash twrp or root it says 'FAIL'.
Can someone please help?

Hi,
Sorry for the late reply -
just to clarify, are you stuck after point 2 of the guide (as root is the last step of the guide/only mentioned there)?
Personally I did root not via the toolkit but via TWRP when I flashed the custom rom (as described eg in the lineage os thread).
Problems with flashing TWRP I could think of:
- bootloader unlock not successful
- debugging/developer option not enabled
- TWRP not flashed as recovery
At what point does the toolkit report fail (maybe your problem is also worth posting in the toolkit thread)?
Alternatively TWRP could also be flashed with MiFlash (did NOT try myself - but there should be guides around somewhere).

Hi there,
I think (memory blanks setting in) that's the error I got when MiFlash was not running as admin.

Hello. Yes I have posted it there and the questions and answers section to which bkores (the one who made the axon7toolkit) replied and asked me to do a command in which I followed and replied to him with the results and he didn't reply after that. Also, bootloader is unlocked. This is what happens:
Checking ADB/fastboot connectivity...
ADB device connected!
Rebooting to bootloader...
Checking fastboot connectivity...
Fastboot device connected...
Flashing twrp...
And within a second an error message pops up with a red cross 'Flash failed!'
Sorry, I forgot to say that I couldn't follow your guide entirely because I think we are on different versions of the toolkit. I am on the latest version 1.2.0 (stable), so I don't have the option 11 to go to advance settings to install the twrp. I have just the option 6 to install directly(you can see in the thumbnail of axon7toolkit post).
Thank you so much for this guide ! Had the phone back in october and i unlocked it using tenfar tool but since it was stolen in march, i bought a new one last week and this is so much simpler and safer !

Did you try booting to recovery after the failed flash attempt ? I had the same issue with the fail message (toolkit 1.2.0) but twrp was running fine.

HURRAY! ! !
Well no it didn't work until today I tried the option to restore from bricked device to b10. Out took me to miflash and asked me to unlock bootloader? Dunno why, it's already unlocked, anyway , after that was successful I went back to the option page of the toolkit and selected 'install twrp', and this time it flashed! It didn't stop on the 'failed to flash twrp' message but still gave me a 'flash to boot into twrp' then I followed your advise to go to twrp directly from there and it had installed. I'm so happy thanks loads dude. :laugh:
Worked like a charm! Thanks for posting the guide
Edit: Went from locked Nougat to Unlocked Lineage.
Whole process took me about 2 hours, but if you are better at following the steps than me you'll probably be able to do it in 1 hour.
Hello, all!
I've been running Nexus v4.0.5 on my Thor device for a couple of years, but I'm more than ready for an upgrade. An upgrade to CM 14.1/LineageOS, to be exact.
At this point, I have a rooted Thor device with Safestrap v4.0.1 installed; Nexus v4.0.5 is installed in the STOCK ROM slot.
From what I understand, I need to unlock my boot loader, install TWRP, and then... something. Can anyone tell me how to go about unlocking my bootloader, installing TWRP, and doing everything else necessary to get CM 14.1 installed?
Oh, and if you're wondering exactly what I've done to this device thus far, check out this guide I made a few years ago. I've done all the steps outlined therein.
Thanks!

I've gotten to the point where I need to upgrade TWRP to the latest version, but I can't seem to get fastboot to recognize the TWRP file.
I'm using the command
fastboot -i 0x1949 flash recovery thor-twrp-3.1.1-1
thor-twrp-3.1.1-1 is in platform-tools, and that's the directory I'm running these commands in.
Do you know what I'm doing wrong?
Thanks!

Hah, yeah, that's it. Totally forgot about file extensions.
So, I've gotten TWRP flashed, and I've flashed LineageOS and GAPPS according to the instructions here. When I try to boot up, though, I get stuck on the "Welcome to your Kindle Fire HDX" screen; it gives me the option to restore data from a previous device or start fresh. Since I don't have an internet connection on my device, I can't do anything related to my prior devices. And clicking on the start fresh option crashes the start-up program and sends be back to the language selection screen (which pops up just before the "Welcome to your Kindle Fire HDX" screen).
Now, before I flashed GAPPS, I didn't have this problem. The "Welcome to your Kindle Fire HDX" screen didn't show up, so I was able to set-up the OS and use it.
I've tried wiping the device, restarting, and reflashing LineageOS and GAPPS (both in a queue and one after another).
Any idea what's going on?

- insure bootloader is unlocked; unlock again if uncertain
- be sure to wipe system & data partitions before flashing LinOS
- ROM and GAaps (7.1/arm/nano) should be flashed in one operation
- if still no joy downgrade to TWRP 3.0.0-1 then try again
- as a last resort flash Fire Nexus KTU84Q (just one file), boot and allow ROM to initialize, then return to TWRP and reflash LinOS + GAaps
The above may seem a bit random but there's a reason behind each suggestion and the order in which they are presented.

So, I can't seem to get fastboot to run unlock because fastboot isn't recognizing my kindle as a device. When I go to Device Manager, my Kindle is under Portable Devices, and if I browse for drivers on my computer, I only get "MTB USB Device."
Any advice?

We are all ignorant about 99.99% percent of the world around us with unique 'points of light' distinguishing various individuals; never apologize for being ignorant!
Possible solution:
- boot into TWRP (turn off tablet then restart by pressing <power>+<vol-down> together; release first logo appears)
- tether device to host PC (assumes Windows)
- tap Reboot
- tab Bootloader
Above sequence should place your tablet in 'fastboot mode'. If the word 'Ready' appears on the tablet screen the correct drivers are installed on the PC. If not follow previously posted procedure for updating drivers.

True, true! Thanks for your kind words, Davey!
And thanks for your help with this, too!
I was able to boot into fast mode, and I went through the unlock process again. With that done, I tried to reflash LineageOS and GAPPS, but I ran into the same issue I did before. So I did a bit of googling (which I didn't exactly think to do before :C), and apparently this is a known issue for CM operating systems.
Here's the fix.
Swipe down (a few hundred times) to get the notification tray. Go to settings. Turn on wifi. Problem (probably) solved.
Thanks again for all your help, Davey! I wouldn't have gotten Nexus running back in the day without ya, and I wouldn't be running LineageOS right now if you hadn't been my savior a second time around. And in addition to my thanks, sorry for not googling first! It would have saved both of us a bit of trouble, haha.

Hey - glad you got it working and left a solution that hopefully will help others who encounter the same issue. Enjoy your rejuvenated device!
Hi folks,
Today it's a great day for me : I have successfully patched the kernel to have a 100% working TWRP 3.2.1 for our Maze Alpha 4G.
I have port a Jemmini build for Bluboo S1 and I have patch the kernel to have a working touch panel
I have followed this Thead
For the Maze Alpha 6G version, you can test it and tell me please.
How to flash:
I Fastboot method (must unlock device) :
1- Reboot your phone in bootloader mode : adb reboot bootloader or phone off, press and hold at the same time POWER and Vol+ buttons
2- Connect your phone to your computer with adb/fastboot already installed
3- Unlock your bootloader : fastboot oem unlock (it will erase you data, only data)
4- Flash the recovery : fastboot flash recovery recovery_maze_alpha_4G_twrp-321.img
II SPFlashTool method (no need to unlock device) :
1- Download latest version of SPFlashTools.
2- Execute it and load the provided scatter (the recovery image must be in the same folder as the scatter and must be renamed to recovery.img) then press "Dowbload" button
3a- windows SPFlashTools users : phone off, press VOL+ and connect it to your PC (running SPFlashTool and waiting for phone connetion)
3b- linux SPFlashTools users : phone off and connected to PC , press VOL+ and POWER while your PC is running SPFlashTool (with sudo) and waiting for phone connetion.
Update : you can found here the latest version: TWRP 3.3.0 for MAze Alpha 4Ghttps://github.com/dreambo/android_device_maze_alpha/releases/tag/3.3.0
have a nice day.
Works great on Maze alpha 4G. Thanks.
But I forgot to save original recovery...

Thanks. Can you share stock recovery.img, if you have it? I have recovery-verified.img from V05 but I don't know if there is a new update and if size is correct: 11,54MB. Your TWRP recovery has got a size of 14.24MB...
Can you make a small procedure on how to install it? Will help many nOOb's out.
And people need to report back issues and successes !!!! Again I see many questions and people with issues that we seniors try to help out with that end up in no more response which to me is not done and not helping others.
I have a 6GB version that I could test on but at the moment I am using it for other stuff and I can't risk bricking it this week.
Would finally love to start some stuff happening on this phone.
Ok in the process of doing so on my 6GB/64GB version.
edit : congratz I now have a 'phone' that can only go into TWRP . Should have never ever done this!
Says no OS installed ... really nice
Edit 2: after hours wasted was able to get your zipped rom on the Maze but I got no boot with that TWRP, so flashed recovery-verified.img from the 6GB rom from Alpha I had downloaded ... It would then start up but show 4GB out of 6GB. No good but at least all the rest seemed to work. All other effort to get it going back with the proper kernel etc resulted in frustration.
So now to flash the official rom back via their tool... that one got me really frustrated and was completely my fault that I couldn't figure it out. But you know angry, frustrated, must get it back to work, can do this ... After all these years of toying with phones we are so used to pressing 'power and vol+ or vol-' together to make something work. Now in the end I re-read the manual again and saw that you only have to push vol+ and NOT vol+ and power together or it wont go in the mode it should go to make it flash!!
In case this happens : The best advice I can give to people is to download the proper MTK drivers. Search for vcom drivers for MTK and you will find.
Print out the instructions and mark every step you do to the letter. The flashing itself only takes like 3 or 4 minutes

Haha I did the same exact thing..and managed to get it working after flashing it with the spflash tool but the trick is if you have Windows 10 latest version you won't be able to do this..at least I couldn't because of driver incompatibility so in my case:
1 I installed Windows 7 and installed mtk drivers for spflash tool
2.booted into twrp
2.1 if you can't boot into twrp or it doesn't turn on you can still try this
3.Start sp flash tool and download the zip the one(in case of trouble)that the moderator published
4. Load the scatter file and make sure that all of the files and the scatter are in the same folder.
5.click download and leave it like that
6.plug in your phone in fastboot if you can't try one of the following
6.1 just plug it in turned off and monitor spflash tool status
6.2 plug it in holding volume up key (just volume not power)
6.3 in twrp go to boot and boot into bootloader
And the tool should do the rest
If all else fails check the drivers one more time
After all that if you are feeling adventurous flash twrp one more time and do not factory reset through twrp ! Because that was the problem in my case and after you unlock bootloader boot your phone and go through the setup without setting the password because twrp will be locked.
Good luck.

Wait a sec., missing a couple of things here.
1) Do you have a 6GB ?
2) In case you have a 6GB did you manage to get it working, rooted and all?
Your point 6) well I flashed mine on the latest 64bit win10 ... but.... if the phone is off and you connect the usb cable my phone tried to boot up either in twrp with no com port. Also booting it in bootloader doesn't make the comport visible so you can't flash.
The only way to make mine visible for the flashtool was to press vol+ and then connect the usb cable.
Btw I am glad someone finally responds and spreads information. A very good post! Your first 'thanks' well deserved!
I wonder where the guys are that I was trying to help. Did they throw their phones away or something? Sharing is caring I thought.
I want to root mine to alter the camera settings and the media xml file. I find it strange that our sensor, which is the same as in my wife's Xiaomi's, takes seriously bad pictures.

Sorry forgot to mention I have a 4 GB version but since maze is not providing the roms on their website any further development will be limited..thank God for dreambo he is the only guy doing any work here and like you said nobody is responding to any questions asked..shame really because maze is a great phone with a terrible camera..which drivers did you use on Windows 10? because I tried a hundred of them and non of them recognize my phone..and in adb I can run the command fastboot reboot bootloader but after reboot none of the commands are working .
And yes I did manage to install twrp and root using magisk and I to hope that all those other guys didn't brick their phones

This is the filename I used on Windows 10 VCOM Drivers (All MTK Devices & All Windows OS version).zip I think I downloaded it from XDA somewhere.
Also something you must know https://www.howtogeek.com/167723/ho...8.1-so-that-you-can-install-unsigned-drivers/
Another thing I experienced is that one USB connector is not the other one on a pc. Always connect it to the ones directly on the main board next to the other device outputs like audio etc. and preferably not go through ones that have been extended via a cable like the ones on top of the casing or so. Also a must have application is usbdeview.
Well should be easy to get it going if you can boot it into 'fastboot' then you can try as much as you want to. But djeeeeezzzz the letters are very small when you boot it with a power+volume up . Also check that volume up will toggle between 'fastboot', 'recovery' and 'normal start' and volume minus will select it, not the power button which would be more logical to me.
I might have another go at trying to get it working on my 6GB but it involves having a lot of time and knowing that I will get frustrated. Installing all apps and settings is also a time consuming thing. Once you have TWRP on it it all becomes easy to backup. So many things to test or try.
Maybe dreambo has an idea on how to get mine up to a 6GB one as it is probably only indicated in the kernel.
Anyway I will continue to write down my progress.
Ok more frustration. Done multiple things to try to get this running. It's good to know that the original rom is easy to install again after practice.
Take 1: Try to install clean 6GB rom and immediately install TWRP.
Results: Dreambo forgot 1 step and that is to allow OEM unlock in the developer options. If you do the adb command to unlock press volume up and it will unlock (very hard to see, very small letters on the display in bootloader mode)
Well TWRP starts but immediately I get a message 'mount decrypt data password' which I tried a couple of things but no go. Also googled... different solutions but always ending in a bootloop to TWRP
A possible solution that I read was to create a startup pin .... no go 'pin not valid'
Take 2: Take all the rom files and change the scatter file with the one dreambo provided.... Thought it was successful but ended up with the same Chinese recovery. Trying to figure out why since the filename was correct like indicated in the scatter file. Came to the conclusion that the original file was/is called recovery-verified.img and not recovery.img. Really really strange this one as in the original scatter file it also points to recovery.img. So this one I will have to investigate. Renaming the TWRP file to recovery-verified.img lead to a error during the initial scan of the flashtool.
So moral of the story is that I am back on square 1 and lost 2 hours today (plus putting all apps and settings back) today.
I get a bit lost, is this TWRP method only working with the 6GB or also with the 4GB version?

There is no fundamental difference between 6G and 4G version.
It must works in boat versions.
If you have issues with SPFlashTool try this (no need to install any drivers on Windows 10) :
Put the preloader.bin (found in the rom package designed for SPFlashTool) in the same folder as the recovery.img without checking it the list of partitions (only recovery must be checked) and click on Download to flash the recovery, as usual.
Perhaps SPFlashTool cannot read by himself the preloader in the EMMC, and we must provide it.
The linux version of SPFlashTool not works at this moment, I do not know why
With the SPflashtool I always get the error:
ERROR:STATUS_DA_HASH_MISMATCH (0xC0070004)
HINT

Hello
I had the same problem, (error BROM ERROR: STATUS_DA_HASH_MISMATCH)
what I did: I use Windows 7 System
1- clear all drivers for smartphones with "usbdeview-2-17"
2- install Drivers "Drivers_Auto_Installer_v1.1236.00"
3- install "PdaNetA4170"
4- use "SP_Flash_Tool_v5.1708_Win" to flash the rom. first flash the preloader alone and then flash the others.
the problem was the bad installation of the drivers, after that everything went well for me.
try it can work for you too.
the mentioned software is easy to find on google

If there is no difference between the 4GB and 6GB then why did I literally spend days on trying this and documenting what happened?

I only have the 6GB version of the Maze Alpha. But you wrote that the procedure should work for both versions. I think I wrote down what happened with mine if I installed TWRP.
I tried both the 'regular' flashing and then the full rom install with the trick to put the files in the directory and rename but both ended up as I've written in my previous post.

From times to times, I notice trouble with flashing using SPFlashTools.
First (when I post my first post relating of the root) I use the linux version : no issues it works perfect, no need of any drivers!
Actually, no way to have it working on linux, why I do not know!
I have tried Windows 10 and I notice that we have to provide the preloader to have it working, as I write in my post.
In theory, and only in theory, the SPFlashTool must works the same manner in any phone with a Mediatek SOC.
But in reality, we have notice that with exactly the same phone the flashing procedure works for some users and not for others!
SPFlashTool is a very capricious software, there is no warranty to have it 100% working in any platform, even with the same OS.

The thing is that I have no issue with flashing the software as I can perfectly flash the original rom. The problem is that when flashing the TWRP file, in both options by the way, so also via method 1, I get a boot loop.
RCA 10" Touchscreen Tablet PC/DVD Combo Featuring Android 6.0 (Marshmallow)
*No idea why it says PC/DVD as its Android not Windows.
ASIN/Model numbers: ASIN: B077L4VBHK Model: DRP2091
RCA typical RCT number: RCT6603W47M7
Chipset/CPU: MT8127
Ports: 1x Mirco USB (supports ADB! etc. unlike VikingPRO), 1xUSB A, 1xHDMI (mini i believe), 1xMicroSD slot (supports up to 128GB)
Special: 1xDVD/CD Reader/Drive. has unlockable bootloader via fastboot oem unlock
Root Attempts: (Failed: KingoRoot, SRS, KingRoot, RootMaster)
MTK Droid Root & Tools and SP Flash Tools don't seem to work right with this cant create scatter etc. (i assume because of MT8127)
Links:
Walmart/Wally World
Amazon
if any dev could help me root this and get custom recovery would be great.
UPDATE: Thanks to NepoRood (and my testing) theres now CWM recovery (attached to post extract zip and flash img via fastboot flash recovery command.) unfortunately we were still unable to get root access.. if anyone has this device or wants to help root this pm me.
Additional files attached maybe someone can build me cwm or twrp for this as i could never get anything to build for mtk devices.

I found various firmware downloads, but need to know the exact type of firmware you are running.
Example of one I found: rct6603w47m7-android6.0-v23-v2.15.80 (<-- underlined part is what matters)
If you boot into recovery, it should show you the type of firmware you have.

DRP2091-android6.0-v62-v1.19.90-E02
*also says on very bottom of screen "supported API: 3"
**DRP2091 is rct6603w47m7 not sure why there's so many different model/serial numbers referencing the same exact device...
also i managed to dump the whole device via SP tools readback on linux so if anything beyond recovery or boot img are needed i should have it.

That version isn't on the site (or any v1.19.x), I'll download the images from the OP in a bit and see what's inside...

Had the same issue also I came across a bunch of ota test files on a Chinese site but links were dead and because no ota update is available i can't grab the ota url or file name. So ended up hitting a dead end.
Would it be possible to bypass the activation code screen with cwm or twrp? Or maybe put a different version of android on the tablet, other than marshmallow.?

I've got the RCT6603W47M7 tablet, but here in the UK it goes by the name of RCA Neptune 10.1L.
Problem is I have bricked it and I am now trying to recover it using SP Flash Tools. I have tried 2 different stock ROMs, only to have nothing but errors and interruptions during flashing. (errors 2004 and 4008). My tablet is fully charged yet it will randomly disconnect during flashing. I've tried both the MTKAllInOne.bin and DA_SWSEC.bin but I still get the same problem either way.
I've tried different USB ports, different cables and the two download agents that I just mentioned but I am stumped.
I wanted to try the ROM found here https://www.needrom.com/download/rca-rct6603w47m7/
But as I don't have a premium account I cannot access it.
Any ideas? This is very frustrating.

Thank you for your reply, I was worried that this discussion was dead. That's frustrating to say the least! Damn! Well, I don't know if this will work but I found another device that is also a MT8127 and has exactly the same spec of this tablet. My point being is that I found a TWRP image for that device, and because it's the same chip set I assume that it'll work for this device too?
If I can get my bricked tablet to even turn on I shall try it. It also makes me wonder that if we were able to root the device, would we be able to access the internal storage by normal means? By using the micro USB ? Either way it'd be great to have it rooted.
I stayed up all night last night trying to flash this tablet and still no luck, it keeps disconnecting half way through.
