The Dell Venue has been rooted!

[DEV] DELL VENUE 7/8 Intel Rooting / Development Discussion
Dell Venue 8 DEV-EDITION conversion
I think we need a dedicated board for the new Venue tablets. I would like to get mine rooted as well.

I am waiting for the BF deal to get Venue 8 for $129. I also want to know if it will be possible to root it.
I am newbie to rooting as well, but I guess the first thing is to unlock the bootloader. Am I right?
What is Dell's previous attitude to locking the bootloader on their Android devices? Will it be possible to unlock this device's bootloader?
I would imagine that root will be possible at some point. It is running pretty much vanilla android. (I am glad dell didn't add all their bloatware)
$129 is an awsome price for this tablet. It tests out on Antutu much better than the Note 8.0 and $129 puts it almost $200 less. (Not counting what Samsung will do for its own BF deals)

Amazon just dropped the price by $20. $109 now and the 32G was $159. I went with 32G. :good:
I also just bought 32G version.. Great deal and free shipping with Amazon prime

which amazon site? i just checked both us and canada site and the us isnt even mentioning the 32 gig and the 16 gig is still 179 and canada site doesnt sell em yet this is valid as of 657am eastern standard time
I just ordered one from newegg. They're offering the 8" 32gb model for $159.99. Amazon has the 7" 16gb model for $159.99.

I got 32GB Venue 8 from Dell for $149 shipped Thanksgiving night. Got the Targus Folio case for $15 there too. Ordered an Armorsuit screen protector from Amazon for it, and already have it. lol
So, I ultimately decided not to get this 8 inch tablet. Instead got the Nexus 7, which should offer immediate OTA updates and more developer support.
The official Dell support for the tablet seems to be lacking as there are two or three issues still unresolved at their official forums. And I think the Venue 8 Pro Windows 8.1 tablet is getting much more popular, so Dell might offer more support to their Windows line.
Maybe all we need is a Clockworkmod recovery or TWRP recovery?
I found out that the bootloader is unlocked, that means it's ripe for the pickings: http://forum.xda-developers.com/showthread.php?t=2551863
EDIT: I gave some more thoughts into this rooting method and realized that using Motochopper wouldn't work because it will attempt to install an ARM su binary. The Dell Venue 7 & 8 are Intel x86 tablets, we must find another rooting method. This is just purely a hypothesis as I haven't done any detailed analysis of the Motochopper exploit, but maybe we can substitute the ARM su binary with an x86 one from the Galaxy Tab 3 10.1 or ASUS MemoPad FHD 10.1 forums.
I know that both of these tablets have successfully gained root, the Galaxy Tab 3 10.1 requires the tablet to flash a modified system image with su already pushed into it through ODIN and the ASUS MemoPad FHD 10.1 requires the same process through fastboot. I know fastboot is already unlocked on the Dell Venue 7/8, all there is now is to find a way to include the x86 su binary into the Dell Venue 7/8 system image and we can just flash it into our system.
This will likely mean that we need to find a way to extract the system image from these tablets and then manually install the x86 su library to /system/xbin/su and then also bundle SuperSU.apk on the system as well.

maybe this could help...Ramos i9 has the same processor our Venue 8 and has been rooted.

That set of instructions requires adb root, which doesn't work on the Android build on the Dell Venue 7/8. Since it's a production build, adb root doesn't work without the device rooted already.

With an unlocked bootloader root should be possible without too much trouble. I have gone through this process on an older phone, and hopefully we can work it out for this device without the need to get a real developer interested in the device. From my experience, the starting point is to get ahold of an image of the boot partition for the device. This can be unpacked, modified, then used to boot a device that has an unlocked bootloader. If that works, a temporary root shell can be opened on the device and permanent root obtained from there. If Dell has released the firmware for the device, then getting the boot.img should be easy. If not, then once an update is released the new boot.img can usually be extracted from the update package. I have looked around a bit, but could not find the firmware for this device. If anyone else can find an image of the current firmware, post your findings here. Otherwise, I will keep looking as well.
I am actually still waiting for my device to arrive, and will start tinkering once I get it. In the interim, has anyone tried some of the other root methods for 4.2?

I've been trying to extract boot and system but the methods I know on Linux requires root (dd) so I'm not sure how to extract them.

"pretty decent" is very polite. Personally, I find the battery life mediocre. I know that PressReader is an energy intensive app but Venue 8 should not loose 35-40% of its charge reading a newspaper.

Not sure how that's possible because I've been playing with a Dell Venue 7, and I can surf the web and play a few light games and it still has about 8 hours of battery life.
Though, not sure what brightness you set the screen to, I manually adjusted the brightness because the Dell Venue 7's auto brightness never seems to get the brightness settings correct, I always find it too bright for my liking and the screen brightness seems to be what eats up the battery the most.

I recently received a Kuno Tablet. It has the same physical characteristics as the 10.1 except for the lack of a hdmi out. Its running android 2.3.1 with a 1.2ghz processor. I have been trying to find some way to root this tablet for a few days now and have had no luck whatsoever. As far as I know no one else has even attempted to root one of these. Help of any kind would be appreciated and I will do my best to answer any questions. I am considering trying petes root tools or gingerbreak but i have my doubts that this will work. I have tried to put the device into some sort of recovery mode but have had no luck so far with any of the button combinations I tried.
Hi xsurferx,
the Kuno really looks like the Archos 101... the chinese engineers are incredible.
Under the hood there's different hardware working.
The manufacturers website mentions a [email protected]
http://mykuno.com/kuno-specs.html
Due to this fact there's nothing in common with the way Archos created the firmware on the A101 and the way you could root this device.
You could try to find out how the firmware looks like on your Kuno... but i guess this is not the right place to discuss these things.
Anyway, good luck!

Progress
Any progress on trying to root the Kuno tablet? Superoneclick says that it roots it successfully but Superuser does not get installed. Is there at least a way to flash Gapps onto it? I can't even set up a gmail account unless I use the IMAP settings
super one clicks havent worked for me yet either however, i do work for the high school that i attend on their tablets and anything else they need done, through contact with the company that created the tablets ive learned that the tablet does not have a recovery mode and that the tablets actually have to be imaged like a computer would. So once i get my hands on an image i should be able to modify it to allow root access. If that fails im going to try rooting it through adb and installing superuser that way as well
what shcool has the funds to buy tablets like that?
So you just help them>?
lots of them
Many schools are going to one to one devices to try and help students learn and while they are expensive most of it is payed for by grants and other funds. I do anything they need from pc to mac and android. The tablets will be given out to freshman this coming semester and they want to see just how locked down these are and im assuming that rooting them will be the first step to unlocking them from the cirruculumloft software they are using. They want to see how to unlock them so they can prevent it in the future. Which is where i come in.
Status...
The kuno tablet has a recovery system that can only be accessed by flashing a new firmware to it, however, it is not possible to get this firmware without getting it from the company that made the tablet. So...in order to root the tablet you have to create a custom firmware from scratch for the tablet because the firmware on the tablet was designed in such a way that the android market can not run on it. The company removed the directories and other items the market needs to run. You can not connect the tablet through adb, nor can you install from SD or even access the SD card from inside the firmware the tablets are currently running. In order to root this tablet we would need to create a custom firmware and then flash it onto the tablet. Anyone interested in trying? Also, super one clicks will brick the device, I'm surprised yours still worked after that.
new discoveries
The market will run on the tablet, i was lied to on that one. The tablet connects through adb very easily and most commands work in adb. unfortunately you can not reboot into recovery or the boot loader through adb
unrevoked won't find my tablet. what do i do now?

http://lmgtfy.com/?q=unrevoked+won't+find+my+kuno+tablet,+What+now?
I work for a company that will be selling these Kuno tablets to schools. A CurriculumLoft Employee told me these tablets are not approved by Google so that makes them not able to use the android market. I have found that these can use the Amazon App market.
Figured it out!!!
After working on this for the better part of 6 months i have finally achieved root and flashed a custom rom with CWM recovery installed. I found that the Kuno tablet is essentially the same as the Arnova 10 G2 tablet with the exception of hard drive size. Here is the link to the site and instructions i used to flash the rom. If any one has any questions let me know.

HELP
Hello. Questions, what is adb and i've found a site called blapkmarket.com which lets you download apps if you have firefor installed on your kuno. But my firefox browser crashed so i unistalled it and i cant download apps anymore. My last resort is to reset my Kuno completely and take it to my media specialist. any suggestions ??

Not sure this is the right place to post this but here goes. I just bought a Polaroid P10 tablet today. I wanted to root it, but can't find any information available about this product except unboxing videos. Running Kitkat 4.4.2 Kernel 3.3
I found a root using towelroot, but when I click on the icon, it just opens up a page with code and doesn't do anything. I'm a total noob and don't know much about rooting, but people tell me it's the only way I can add my own content. Any help is appreciated. Please and Thanks

That's a shame. It's a nice tablet. Hopeful that someone will be able to get this thing rooted. Just so I'm clear about "rooting" all this really does is allow installation of apps and music and stuff that was not downloaded at the app store, right? I mean, I'm sure it does more than that if you're a hacker and know what you're doing, but for me, this is the only perk to rooting. I guess I can wait. I only paid 75 bucks for mine. It was 99 originally but 20 percent off and the cashier also gave me another discount cause she was cool. I will keep checking back here in case someone has some good news! I forgot to add that I cannot get my laptop to download the driver for the tablet when I try to connect it.
Er... I'm not sure if the tablet is different but on any other android device I've ever used you can do all of that without root. Feel free to look up "How to enable from unknown sources android" . All it takes is checking one little box in settings. for apps I personally prefer the app from aptoide.

OK, see I was mistaken about what rooting meant. The first tablet I ever had, I HAD to root to get access to the internal storage. I will try again with this one to even find the internal storage. BUT, I just got this tablet yesterday and already it's resetting itself when I turn it off. I will try to start it and it gets stuck on the loading screen for a while, then It will load and I have to re enter all the setup info. Pain in my a**. I'm taking it back to exchange for a new one in a couple days.

Well I have the Polaroid q10bt that I bought @ Menard's last week for $99 cpu z says it is a p10/q10/ptab1040/ptab1041 I think this is the same as big lots 4gig but mine is 8gig. It is a really nice tablet 4.4 kk quad core processor. But yes root would be really nice. I've tried using kingo root with pdanet driver, (no go) also tried iroot apk app & there PC program which are Chinese to root those failed. Also tried framaroot & even other Chinese root programs I found on YouTube those failed as well. So next I seen that CPU z said my q10 has a all winner a31 processor so I Google root all winner a31, found 2 different zip file apps that u run from update app using stock recovery but yet again those failed. CPU z says tablet is rooted but super su won't update the binary? Well that's all info I have. Hopefully we can work together & hack this bad beast lol! Thanks in advance ppl & have a blessed day! Ron.
I'm gonna try king root on this. It's another Chinese root method & they have apk app & PC version
Dont try Vroot or Kingo theyre malware
Here is working root for the Polaroid Q10/P10/etc. and possibly other 4.4 a31 tablets
Instructions
Make sure you have ADB installed and working for the tablet, it will work with standard ADB drivers, just look it up im too tired to tell you how to make ADB work
1. Make sure USB debug and Dev mode are on
2. Go to settings, backup & restore, then boot into recovery
3. In recovery select ADB sideload and then in cmd prompt type "adb sideload (path to .zip)" and let it update
4. Reboot and enjoy root
This was about 5-6hrs of experimenting, credit goes to those who made SU, Chainfire for SuperSu, etc.

yea NP
took me a bit to figure out what exactly the issue was
The other a31 root zips arent for 4.4 and dont install all the needed files and permissions for it to work properly in 4.4. I was working on it and remembered chainfire saying something about it a while ago so i found a script designed to install from stock recovery and modified it to work for our device. I might work on a recovery but cant make any promises.
also, once you have root be sure to lower your screen DPI to 120, it makes the UI a bit smaller and in general things tend to look a bit nicer at that DPI on a 1024x600 screen (that should be the screens native DPI)

So I shared your root method with a p10 thread over at www.freaktab.com but made sure to give u all credit for figuring it out. Since I tried all the other root methods but failed, SuperSU installed it self as a system app & wont uninstall & CPU z says tablet has root but SuperSU wouldn't update binary. So question can i still use your root method or would I need to do a factory reset either thru tablet settings or stock recovery. Thanks in advance & have a blessed day! Ron.

Hey so I actually just used the update app built Into system to boot into recovery & then I just flashed zip file from stock recovery, then cleared cache & rebooted. Then I updated su binary & was good to go. Do u think doing this way was OK being as I now have root or should I have done adb method & side loaded it or should I still attempt to do it that way. Also what do u think about over clocking stock CPU using no thrills CPU or do I need a custom kernel? Also do u think a custom recovery would work on this? Well thanks in advance for all your help & have a great day!!! Ron.

no if it worked that way is fine too :] w.e works for you to install i just listed the way i did it. as for overclocking dont set the CPU higher than 1.3ghz or itll lock up as we dont have the ability to adjust the voltage atm. Im working on tearing it down and seeing about updating the screen and getting an SD card to work on custom imgs.
I can tell you its using DDR3L 1333 cas latency 9 and is an Allwinner A31s so far, looking into the other chips to figure if its close enough the the A31 dev board to use the kernel source. Display idk yet, cant get the battery off safely as its glued down pretty tight but i think its the same as a tablet called the Q102. These might be just rebranded versions of those. If we can find a better display that works with the Q102 and a speaker that is the right size we could mod it for better sound and display. Im searching Aliexpress and alibaba for a display thats possible to use. I anyone can find another 10" tablet with a similar size and shape using an a31 with a better screen we might be able to do a transplant.
edit: added board pic, nand is toshiba tc58teg6ddkta00 and bt/wifi is Realtek RTL8723BS, the RT is used on some Rockchip boards so should be able to get drivers for it. Once i get an SDcard ill work on recovery and maybe a custom SDcard img as the hummingboard a31 kernel looks like it might have the power management stuff in it? not sure if the hummingbird a31 using hynix nand and ram will be an issue.
Well, managed to get stuck in recovery bootloop and cant get out of recovery. Im contacting southern telecom for the firmware img but we'll see if i can get it, device works just cant get past recovery xP

Yea perhaps, but im not gonna ask for hardware donations because i got ballzy and didnt wanna wait for an SDCARD lol and i know we knew it was A31 just wanted to confirm because sometimes they lie and wanted to confirm if it was a31 or a31s
If they dont give me the img i will have to try either making a bootable SDCARD so i can write to nand or flash another tablets firmware and hope it works. I might be able to fix it if someone dumps their nand/partitions and then i could try and make a bootable SDCARD and write the stock recovery back in terminal. You can pull the partition imgs through ADB on a running system., probably shouldve done that before i tried to mod recovery lol wouldnt be so bad if i could get usb access in recovery but cant.
EDIT: Looks like im going to have to do the dishonest thing and exchange it at the store saying its broke as they told me there is no firmware available.

EDIT: Looks like im going to have to do the dishonest thing and exchange it at the store saying its broke as they told me there is no firmware available.

I used romtoolbox try that
Also i suppose it works out as its 50$ off so ill get an SDcard and work on a bootable SDcard fr nand restores in case something similar happens. Also word of warning, phoenixsuit doesnt seem to recognze the tablet for some reason, drivers work and all but in FEL mode you cant flash with phoenix it just fails. Number one priority is finding a bootable nand restore method from sdcard. Make sure not to try any other a31 imgs as you maybe soft brick it and not be able to recover.
So far this tablet seems to be pretty modable as long as we find parts that will fit/work. All the peripheral devices unplug easily the only difficult thing is the batter which is glued tight. I may have found 1280x800 IPS screen that'll work with it and looking at finding a better speaker.
Got a new firmware update tonight. Tablet seems faster now. Anyone else get it? Glad to see they are still updating this tab.
can't update.
i got error on installing update.
please help me.

i also got the update on my dell venue 7 3740. but it disabled the fastboot, now i cant root it.
Got it as well. Seems snappier. I would like to know what got updated? Kernel tweaked again?
As far as the problem your having golfyrider, reboot them just keep selecting system update under "about tablet" eventually it will download.
It's still 4.4.4 and the source code hasn't shown any signs of change yet either. Still can't pull the boot.img or recovery.img from the device, having trouble splitting the ones from hharte, still no email replies yet, kinda hate to think my email yesterday caused this as this isn't an answer to my questions, I'm just not stoked about an update that is basically the same as previous, going to snatch it and post it for those who think it's worthy of an update. excuse this rant, been sweating out my days and nights trying with this tablet, not going to stop, just isn't much of an update to me. Sound is still distorted, which really grinds my gears. ... ok, I feel an insey bit better. thanks 4 reading my O.

Take a look at the kernel source for the 7840 it has a py script intended to unpack / pack the unsigned images a small modification can be made to the script to take into account the Sig . if you wanna better idea of the Intel image assembly I suggest at signing up for the baytrail bsp from wind river or other vendor.
If your on windows this might unpack the signed image and repack as a unsigned image so you'll need the boot loader unlocked.

Thanks for the tools that'll hopefully help a great deal. I've played with the 7840 kernel code for two days and still was left with a non-flashable boot.unsigned.img, I truly appreciate any help I can get with this. I've tried like 5 different device tree cobinations and probably more than that. Hopefully this will truly bring a light for a breakthrough. Thanks a million social-designs-concepts
Here's the update zip that this thread is based off of:
incremental4.4.4update.zip - 24.09 MBBe advised though, this is a direct download from OTA and unmodified by me other than the name of the zip.
It will temporarily disable your root and does something funky to the button combo of down and power to get into bootloader mode (I used adb reboot bootloader-perfect) but if you already obtained root, you can get it back. theres a couple patches and 3 or 4 libs added. other than that? IDK you check it, lol.
It's good your tablet is still getting updates, the 3830, and 3730 hasn't received any updates since 4.4.2.
Lollipop is suppose to start rolling out to the Venue xx40 series on Tuesday April 21st, I suspect this is a preliminary update to make the device work for lollipop. The 3x30 saw similar small updates days before the JB to KK update.
@vampirefo maybe we'll luck out and get Lollipop too, the 3x30 was suppose to get 4.4.4 and it's yet to be seen so maybe they scrapped working on 4.4.4 when Intel did the 360 on supporting 32bit ART and Clovertrail Plus. Though not going to hold my breath. You also might wanna try building cm12 since the 3830 has an unlocked bootloader , they seem to be making progress with it on a couple of other Redhookbay devices.

You sure about that? I only saw the 7840 mentioned on Dell's support site for the Apr 21 update to Lollipop.

I saw it in a 3740 thread and the 7840 all three devices are merrifield based tablets and the last email I got from dell legal said it was going to start rolling on the 21st and that at this time they have no word on if or when it would be available for the 3x30 I'd post the email but it full of Dell Private Confidential headings.

it removes the 480byte signature and corrects the image flag to be unsigned what ever image it was
boot.img wasn't signed, haven't used or seen a signed boot.img since I unlocked the bootloader on this tablet.
pm-cz scripts leave the signature ? Never checked.

Alright maybe I am missing a major point if dude are capable of unpacking, repacking and all that good stuff, My question is wtf, why not me? what on earth can i do to get the appropriate file sizes to know where the boot sector is so I can extract it and if need be modify a script that'll allow me to do all of this and re-flash it for testing? the 7840 builds so smooth and I am losing my mind. I feel like theres a whole lot of know how in a small click. Initiate me, make me an apprentice, study buddy. idk I'm loosing my mind. Must have over 20GB worth of trials and errors. I'm going to Google the mentions of sdc from earlier but am really not sure of what I am looking for. If I could get a pm tutor that'd be nice. I can do all the work. But nothing I have tried so far has been acceptable. I'm getting other things done but this is my priority goal. Thanks for helping guys. I'm generous when I got it. I fell so behind in learning the specs of this new device to be successful at what I wanna do with it. There I go again giving reading material for the pooper seat. I need to build and sign a Sig for starts, lol, if momma only knew what I did all day and night now, lol.
thanks again for reading my troublesome O.
Normally I'm just a joy, ROFL, heh

The 7840 build script is be able to unpack and repack your boot.img, don't know if it will boot on your tablet as I don't have your tablet and not interested in it, I did download a 3840 boot.img, unpacked and repacked boot.img flashed to my tablet just to see if it would flash, and it does flash without any problems, wont boot cause my tablet is a 3830.
Below is flashing same boot.img on my iview i-700 same results as 3830 both will flash the boot.img but neither can boot from image.
Code:
fastboot flash boot '/home/vampirefo/Desktop/dell-venue-boot-tools-master-3840/boot_script/Vamp_packed_boot.img'

LOL, yeah, if he hasn't unlocked his bootloader, he just been wasting his time. :good::good:

No difference. :silly:
I have an Acer Iconia One 7 B1-760HD that I just rooted with Kingroot, installed SuperSU and replaced Kinguser. Once I rebooted, it booted past the "powered by Android" screen, but freezes on the boot animation. Does anybody have a stock (Recovery/ADB flashable .zip format) ROM that I can install to either fix my problem or reinstall Android.
Hmm same, the Acer website has nothing, absolutely nothing. Have you managed to do anything yet? Maybe I'll return the tab tomorrow and get a replacement, this truly sucks.
Hello! I sent it to reinstall a service for which you will pay, because I did root. Because my warranty is not valid. There is no possibility of backup is not possible to install the official rom, this truly sucks

Yeah I see. Yesterday I went back to the store and got a full refund for the tablet, and so today I went back to a different store and picked up an Asus Zenpad Z170C.
My experience: You can root the device using Kingroot and replace Kingroot with SuperSU safely, this is the method that I used: http://www.w0lfdroid.com/2015/05/How-to-Remove-Replace-KingUser-KingRoot-with-SuperSU.html. This method didn't brick my device. From there I was able to flash the Xposed Framework.
The thing that actually bricked my tablet was trying to uninstall apps using Link2SD, trying to clear the bloatware. The tablet was fine at uninstalling the Acer apps but for some reason as soon as I tried to uninstall the Amazon App Store, the tablet froze and suddenly the systemui was not responsive in a loop. I restarted the tablet, and then it bricked.
Thanks Acer for your abysmal support! I'm sticking to Asus from now on, this tablet has a much wider collection of stock firmware that I can reflash onto the device if something was to go wrong.
Absolutely the same way bricked my tablet. I tried to delete system application using Link2SD. I feel that these have some protection against it.
Anyway sell it and afar off for this brand, instead of enjoying the new device I deal with ****. Thanks ACER I will remember this mockery.
Thank you AwesomeLewis24. Happy New Year
A bit late maybe, but you can download the firmware and kernel from http://www.acer.com/ac/en/GB/content/drivers
Search for the B1-760HD and its available there to unbrick your tablet.... It saved mine

Looks like they have updated the website indeed. Looks like it came a little too late for us though. Oh well, it's good that they've finally taken the initiative to add it.

I recently picked this 7" tablet, a Ematic EGQ377BL, for a mere $35 new. It was a steal, Quad Core, 8GB storage, 1GB of ram, with an external SD card reader.
It looks similar with similar specs to the 307, but it comes with Android 5.0.1
Now I'm just curious, does anyone know how to root these things?
Or get cyanogenmod or another custom ROM working.
As far as port work goes, what is involved?
edit: I tried "KingRoot 4.1" and aparantly this works.
http://forum.xda-developers.com/and...id-2-x-5-0-t3107461/post60709910#post60709910
you can also replace kingroot with super su following the instructions here:
http://www.w0lfdroid.com/2015/05/How-to-Remove-Replace-KingUser-KingRoot-with-SuperSU.html
I am leaving this here, in hopes that anyone who googles this device can find it.
I paid $35 for this device. The screen sucks, but it has an unlocked bootloader, and root works, and the specs are decent.
updated post. Now, about cyanogen mod/clockwerk/team win
This thing has an unlocked bootloader and recovery, so it should be possible
I picked up one of these also and was able to successfully root it following the link in the OP. I haven't replaced kingroot yet because I tried supersume and it resulted in my device getting stuck in a bootloop. I think I'll wait until I can get a recovery or backup of the OS before I attempt again.
