Hello XDA,
I just purchased a new Acer Iconia One 8 B1-850 and was wondering if I could root it.
I see many posts on B1-810 and similar, but nothing for the B1-850.

i want to root to enable the multi user option by updating the build.prop file, i've been able to connect with ADB but the device isn't visible in windows or mac (tried both) when you reboot into boot loader, in fact it doesn't appear to boot into boot loader it just seems to power off (when using ADB reboot command or choosing boot loader from the recovery menu) so i wonder if its locked out somehow??
Need it too. Did anyone find a way to root B1-850?
Thanks!

I too just purchased a B1-850 tablet, but I've figured out how to root it. Really quite simple. Just use Kingroot:
1.) Navigate to https://kingroot.net/ from your tablet
2.) Download the APK for android
3.) Install said APK (this requires you to have allowed installation from unkown sources in the "Security" panel of the settings menu)
4.) Load up the app and follow its instructions
5.) Reboot and try it out
For good measure, I would also unlock the "Developer Options" panel and allow USB debugging (adb access) and such; I did this before proceeding. You'll have to search for instructions on that yourself, its well documented.
This all worked for me this morning! Really looking forward to unlocking the potential of this cheapy tablet.
Kingroot worked first try, just swap their super user program with supersu. I am having trouble installing the xposed framework though if anyone has any tips.
I was able to root, now I need to install a custom recovery. CWM says this model is not in the supported list. Has anyone been able to install a recovery? I need NANDROID backup functionality.
I made a thread walking you through how to do it on this tablet in the guides area but just use flash fire for recovery and xposed install
Did the B1-850 hardware updated in anyway? I was able to root it in June 2016, but after a screen repair and factory reset and fresh rom from acer, king root and all others can't work. I'm stuck without any root options. Any idea?

There was recently new firmware released for this tablet (08/24/16, Build #: AV0L0.RV09RC04.WW.GEN1), and a handful of updates (08/25/16, 08/26/16) from Acer. I have this same tablet, and I'm unable to root after flashing to the firmware released on the 24th, and latest firmware (Build #: AV0L0.RV0BRC02.WW.GEN1) as well. Hopefully someone can find a fix, as the few different methods I've attempted simply will not work with the latest firmware from Acer.
On KingRoot Please click submit search if enough people do they will find a root until then just hold tight.

I have done this a bunch, sadly still no love. It's annoying me not being able to root a relatively cheaper tablet, as these tend to get rooted first since they get in more people's hands faster. Oh well, just have to have patience.
Thanks, I was having problems, two different rooters failed and I wondered if it was the recent software update! The image version on my B1-850 is the same as you have quoted! Please post if you find a solution, some apps that need deleting are annoying.

Which recovery do you install with flash fire; I don't see a link to it in your other thread?
Success!
The latest release of KingRoot is able to root the latest firmware for this tablet. I saw there was a new release of KingRoot back on the 23rd, and it's working as it should. I grabbed the working version here -> http://forum.xda-developers.com/devdb/project/dl/?id=21707
hi guys. any idea how to recover b1-850 from bootloop?
I no its a little late but i rooted mine with the kingoroot one click root apk. Ive installed xposed framework and customized like crazy everything from fonts to boot animation. Cant find a custom recovery tho.
I cannot root it with any of the tools I have tried (Kingo ROOT, KingRoot, etc). Anyone know any method that works?
Acer B1-850. Is this device even rootable?
This device has made an idiot of me. If I can be of any assistance finding a root exploit for this device let me know. I will gladly write a detailed procedure of the process. I made the mistake of assuming since it was an entry level, inexpensive device, the path to root would be simple. Three months later none of the common "one-click" programs has found an exploit. I have a copy of stock rom for recovery so testing is not a problem for me. It's a matter of pride at this point. So much so I found one on sale for $60 and bought it just for this purpose. I have followed every link I can find associated with this device to a dead end. Any help will be appreciated.

Same here, still no root for me. Usually these cheapo tablets are not as locked down.
Still waiting!?
I have given up getting assistance from xda on this device. Its as political here as anywhere else. I don't drive a Samsung so nobody wants to help with root. I've heard every excuse from locked bootloader (unlockable in dev options) to what one dev actually told me,"There's little interest in spending energy on an inexpensive device." I understand, but why misrepresent the site by implying all android devices are treated the same? Hell on the Iconia One 8 thread, it says that the B1-850 does not have a MTK SoC, but instead has an Intel Atom chip. Then they send you to another thread where, of course, there is no B1-850 listed! That's because it uses a MTK8163 SoC. In both tablets.
Ok, so this device came with 5.1.1 and when I plugged it in to let it charge up (even in airplane mode) it had already gotten a hold of 5.1.2.1. So yeah, it installed 5.1.2.1 and after much aggravation and research, I realized I was able to downgrade to 5.1.2 I used the files from here: http://forum.xda-developers.com/showpost.php?p=62986665&postcount=3 to get the 5.1.2 binary file.
It did downgrade successfully to 5.1.2 because now it's telling me "Your device is running Fire OS 5.1.2, Fire OS 5.1.2 (542169020) is ready to install."
Anyway, I've installed the latest official version of Kingroot (4.92 from June 3rd-2016) and it's a no-go.
It will get to between 16%-18% and then reboot itself. Then it will get to about 19% and then Kingroot will crash.
I've tried all the tricks, unplugged my USB, rebooted a million times, installed Kingroot several times, factory reset/cache clear, tried the PC version of Kingroot, removed Kingroot from "Recents" between reboots/crashes and I end up with the same. ZERO results.
If anyone has any insight into anything I may have missed or any other ideas, I would very much appreciate it.
Thank you

You, my friend... Are. The. Man! Thank you. It did hiccup on the first try but the second one was successful and I was able to switch over to SuperSu and all is well. Thank you!
What a dumb thing to cause such an issue. I would have pulled all my hair out before trying this. Thanks again!

Glad it worked out! If you intend to flash a custom rom (CM12, Nexus, etc.) be sure to grab the latest version of FlashFire from here (guidance/tips here). Some earlier versions were a bit shaky on this device.

Yeah, I'm aware of all of those things. These were actually 4 separate tablets (3 for my daughters and one for my mother) and I just wanted to remove the lock screen ads and prevent future OTAs (all of which require root) plus plop on the Play Store.
I don't think any of them care about flashing ROMs, but I hate when a system takes control over my device and prevents me doing what I want to do with it.
Again, thanks for that most obscure of solutions (on top of the other obscure prerequisites)!

I am having the same issue as OP. I have tried not registering with Amazon and it still isn't working for me. I am definitely on 5.1.2 and not 5.1.2.1. I have 3 of these tablets and this is the only one that I haven't been able to get it to work on. The others only took 1 or 2 tries. Anything else I could try?
Edit: Right after posting this it finally worked. If anyone else finds this thread with the same issue, I would say just keep trying. It took me probably 15-20 attempts but it eventually just worked.
Also I had trouble using the kingroot app on the tablet. If you go to the website and dl it to the pc and use kr it works every time

Hey so do you think the blu advance 5.0 hd will be compatible with the work being done on the R1 hd? I would really like to jump on this hype train with my similar but slightly less powerful phone.
I am hoping that I will be able to install a custom rom like R1 users. I also want to root my phone to disable google services in the meantime.

That phone is based on the 6580 SoC, the R1 uses a 6735. There is a site that lists some roms for blu products that may help, I don't know how reliable they are, I have never used them, but if you want to check it out...

I'm in the same boat. I've got 20 of these BLU Advance 5.0 HD devices and I need to root them to gain access to the VirtualSensor app to emulate a gyroscope. I've tried Kingo and Mobogenie (barf-boo-hisssss). I'm wondering if kingo isn't working on these since they have Marshmallow. I read somewhere they originally shipped with Lollipop.

I was able to root mine successfully the long way.... had to obtain a dump of the boot.img / recovery.img using software that I'm not sure of the policy of discussion on here at XDA - compile TWRP - unlock bootloader - fastboot boot the compiled recovery - flash SuperSU to get patched boot.img (kitchen was being dumb and systemless root didn't want to work) - Flash SuperSU in system mode - Convert SuperSU.apk to system app so it doesn't get removed every reboot. I can post my compiled TWRP when I'm back at my office or grab it from my repository that I'm trying to establish - https://bluroms.info . Sorry for the design mess / lack of much there at moment haven't had much free time lately in process of cleaning up the device kernel sources to build from source... its sort of ... messy in there...... can post on github if anyone wants in

I've been trying to root a Blu Advance 5.0 HD for a while now and stumbled on this post. I visited your site but am not sure what a 'Scatter File' is, or in what order I need to do things in order to get root.
If you could provide a little more detailed info that would be very much appreciated.
Thanks!

EDIT: Sorry, to clarify I tried all of the other PC and APK rooting solutions but was able to unlock the bootloader using ADB. I guess I'm just looking for the proper way to root and add TWRP. Thanks!

I found a option in developer settings that is "Enable OEM unlocking" and it makes it so you can unlock the bootloader from fastboot, if you do adb reboot-bootloader and then fastboot unlock it should undo the bootloader for you

I too am trying to root this device, and am unclear on a few of the steps here. I actually found your site with the recovery and boot images independently, really appreciated! I am at the point where I just need to patch the boot image, though I am not sure how to do this. If you could help me out with this step I might be able to put together some sort of list of steps to get through the whole process if you don't have the time.
Any help would be appreciated, thanks!
I know how to install Xposed Framework I'm just having issues on which files to use to install. Can anyone point me in the right direction ? Thank you! My Blu R1 HD is rooted with TWRP. I also removed ads but only one remains ( Didn't show at first but now it stays there no matter what, even with notifications) .
I followed Colton's excellent guide to installing xposed here: http://forum.xda-developers.com/r1-hd/how-to/guide-installing-xposed-stock-rom-t3426100
Be aware that if you allow the phone to accept any of the Amazon updates, you will be locked out from modifying the bootloader or getting root or flashing the phone. I converted mine to the non-amazon version using Colton's other excellent guide: http://forum.xda-developers.com/r1-hd/how-to/guide-convert-to-prime-rollback-ota-t3432499

Thank you so much ! And I have not allowed it update at all. It's running what it came with. Which I believe is 6.1.
Hello, good day, I am searching for a n00b friendly way of rooting an HD 7" thats is running the system version 7.5.1.
EDIT: I managed to root it, but I am now searching for an easy way to install TWRP.
also what custom rom's would you rec?
How did you root you fire 7? Please tell me been searching for ages.
I followed the youtube video: https://forum.xda-developers.com/showthread.php?t=2551661. The files needed are in the notes below the video.
I followed with installing 2nd boot loader and TWRP.
Could one have not just restored to a 7.2.3, for example (https://forum.xda-developers.com/showthread.php?t=1951254), which appears to be prerooted, then used FireFlash to flash all the necessary files?
I'm going through this process myself, as a noob. What I'm finding is that it's fun and not terribly difficult, but that a lot of the information out there is getting a bit old since 2015 or so. I'm taking notes along the way though and will try to share something to help others follow along.
Yes, there is a moutain of info to trawl through. a lot of it quite detailed, technical and not the sort of operation where you can screw up so you have to digest it all carefully.
THEN you discover that it all stopped working about 5y ago and you start again. Very frustrating and hugely time wasting.
As a last resort I installed KingRoot, but now I can't get rid of the damned thing. There's no uninstall option and if I pull the apk , su no longer works.
I'll look at the two links above . Thanks.

Hi...I just found this forum. Can you tell me how you rooted your kindle fire? I have one running 7.5.1 and I can't find any links or downloads that work.
