Hi to all,
I have just updated the firmware to V10.4.2.20 and now the Unlock Device App: Unlock boot loader from Asus doesn't work for me does anyone have a fix for this or a work around?
I'd like to get my TF300T rooted again so I can replace all my apps.
Cheers.

You can find alternate steps for unlocking the bootloader here: http://forum.xda-developers.com/showthread.php?t=2041627
Also, if you need help with rooting or installing a new ROM, I've compiled a set of instructions on my technology blog (thoughtsontechnology.com, my second-to-last post).
(NONE of this work is mine, I just compiled the text and links in one spot for easier access.)

there's no "alternative" unlock method. the link you posted still uses the asus unlock app. the only way to fix this is to contact asus...

Hi I wish to re root my tablet, after the update I lost root and recovery, ma your link to your blog doesn't work for me could you re post please?

Try to re-install the drivers.

philos64 can you explain which drivers you mean....if the user can plug the device into the computer and is recognized then driver issue should be fine as I am able to load TWRP however this doesn't allow root access and the Unlock Device App v7.1.apk is a device resident application.
Cheers
Footnote:
I got it sorted
1. Download TWRP 2.4 and install via fastboot
2. Download this file http://www.mediafire.com/?cr209hb5e2fr910
3. Reboot into RCK
4. Install Downloaded zip in link
5. Reboot and you now have root access.
Let me know how you go
Cheers

Sometimes your TF300 is not any more acknowledged by your PC and it's just to re-install drivers simply

Trouble opening Unlocker_V8

I am trying to install recovery and root the TF300T that I just got. It looked like I needed to start off by unlocking the bootloader. I downloaded the file from the Asus website (V8 unlocker) since it is running 4.2.1. However after trying to run the unlocker, I keep getting "There was trouble parsing the package" immediately upon opening the APK file. I have been able to install other APK's without a problem. I tried 2 different file managers, downloaded v8 unlocker from 2 different locations, tried downloading it directly to device as well as transferring from PC. Still no luck. Is there anyone that can assist with this? Thanks.

Im pretty sure there is a Windows Utility you can try to connect with the tablet over ADB to unlock.

That would make sense, but I've had trouble finding a utility to do so. I will look around a bit more, but there's nor eason I shouldn't be able to run that APK. The V7 one runs fine, but finishes with some unknown error.

Well it looks like I was able to get it rooted, but I still can't install another ROM because I can't unlock the frickin bootloader. The guide that I followed didn't mention having to unlock the bootloader before being able to install the TWRP recovery. I went ahead and follwoed the instructions to flash the TWRP recovery and now my recovery image is shot. I need an option other than the APK tool from Asus for unlocking the bootloader.

The unlocker-V7 worked on the latest jellybean without any issues. I had to contact asus after registering the device on their site. i included the SN and MAC address. I also included a link to the google search results for the issue so they know the extent of it. They did something on their end and V7 was able to run and unlock it. They got back to me the next business day as well.

I've actually been on the phone with them multiple times and I couldn't get it straight with them no matter what. Usually I would get a tech that was of no use and not very technical so I basically gave up and this was months ago.

Pretty sure I have tried both as soon as there was a post here about it but just to make sure I just downloaded 7 from the asus site right now and gave it a shot and sure enough i get a network error, try again, etc. I know they have duplicate MAC addresses on file for me and each and every time i asked them to update their site with my current MAC they talk about "im sorry...we cant support unlocking......it voids your warranty"........blah blah blah...... meanwhile they provide the tool. Go figure. That's why I just said F it I wont buy another Asus product again.

Rooted Fire HD 10 7th Generation Running Fire OS 5.6.0.0

I was able to get rooted and switch to SuperSU on Fire OS 5.6.0.0 by following this guide. I used the google mirror for kingoroot pc since the link on their website is dead. After installing and opening kingoroot pc, it asked me if I wanted to update. I did that and it updated to 1.5.6. I followed the guide for everything else. I don't know if it works on any other fire tablets since I only have the Fire 10 7th Gen. Hopefully it works for y'all.
E: Based on the replies, it seems like it works on HD 10's only.

This could be good... have to try it.

Not working.
Edit: Seems to work for many HD 10. Unfortunately not for mine.

Should have guessed that .If that doesn't work for 5.3.2.0 why would it work for 5.6.0.0? :crying:

Everytime i goto remove root from kingroot, it reboots.

If we can get to that point, can't we use the root accessed ADB shell to push su and BusyBox to system/bin and push SuperSU.apk to system/app for getting root?

Rooting works as in OP
Device: HD 10 (2017) that came with 5.4.1.0 (updates blocked on router)
Like the OP, I was able to root using KingoRoot. Next, I followed the guide to unroot, install SuperSU, and remove KingoRoot. The only "challenge" I encountered was with the unrooting using KingoRoot. After a couple of reboots and rerooting, I realized the instructions call for unrooting using the PC app (not the unrooting option within the Android app).

Would you please be more specific as to how you use PC app for unrooting?
Thank you.

That was where I was going wrong! Once i Unrooted via pc app I was able to achieve root! Thank you!

Just as you did to root with KingoRoot, run the KingoRoot app on your PC and connect the tablet when prompted. Once recognized, you will be presented with an "unroot" option (don't remember the exact title of the option, but it should be obvious). Click on it and wait for it to complete (you will see a confirmation dialog on the tablet as well).
Make sure you have an active shell prompt with su before you unroot.

Just tried a couple of times for the hell of it on Fire HD 8 7th gen on 5.4.0.1 (or 5.4.1.0 cant remember) but it failed.

Tried on HD 8 (2016) 5.4.0.0 and failed.

kingoroot gave "root failed" on HD 8 Generation 7 5.6.0.0

What do you mean by 'failed'?

Root failed for me too for a Fire 8 HD 7th gen

Based on the replies, it seems like it works on HD 10's only, which would make sense cause they have different SOCs this gen and firmware is probably a bit different.

How to root Acer Iconia One 10 B3-A40?

I've got this new tab recently. Has anyone rooted this device? Is there any hope for having the ways to root this device? Dear developers, please, do something for this device.
Thanks.

Just filling in some information holes.

Sorry to get your hopes up OP, I too have the Acer Iconia One 10 B3-A40 and would like to root mine as well. I wanted to add more details about the device to hopefully further along the progress.
The device in particular that I'm talking about it the Acer Iconia One 10
Model:B3-A40
Android Ver:7.0
Security Patch Level: January 5, 2018
Kernel Ver: 4.4.22
Image Version: Acer_AV0N0_B3-A40_RV09RC01_WW_GEN1
Build Number: Acer_AV0N0_B3-A40_9.001.00_WW_GEN1
CPU Vendor: MTK
CPU Version: MT 8167
I'm a super noob when it comes to rooting but a relatively comprehensive learner. With little to no guidance I've attempted to unlock the boot loader and TWRP flash to no avail. I would love to either be told by an experienced rooter that it is either impossible to root this device or the steps I would need to take to root this device.
Thank you all for your time, sorry for the lengthy post.

I'd need guidance too for this device, unlocking bootloader doesn't seem to do much, all power-up combinations simply lead to starting "demo mode"...

I have the same tablet. No luck with rooting tried pc rooting and everything. A Dev on another website said it was unrootable and there is currently no root for Acer B3A40 . Guess the iPad we all have is a waste of money if anyone else has a solution will be greatly appreciated thanks

This device is a MTK device, there is a tool that can build a TWRP recovery for your device for you.

Once you've successfully built a working TWRP for your device, flash Magisk via TWRP to root the device.

If you have the tablet that is in the title of this thread.
This wasn't hard to find at all, it's on the Acer website, the stock firmware versions are listed on this page, click where it says "+OS (3)"
Then download the firmware listed at the top, the one that says:
Date: 2018/02/27
Version: RV09RC01.WW.GEN1
Vendor: Acer
Size: 1,804.6 MB
This firmware exactly matches what is already installed on the device according to the specs that were listed earlier in this thread.
https://www.acer.com/ac/en/ID/content/support-product/7251?b=1
Download that firmware, then follow the instructions in the last method that is listed in the link that I posted with the different ways to build/install TWRP.

The MTK Droid Root & Tools program is asking for the recovery.img file, which isn't in the update file downloaded from the Acer site.
It does have the scatter file and boot.img.
These are all the files in the zip file downloaded from the Acer site:
boot.img
file_contexts.bin
lk.bin
preloader_neostra8167_tb_n.bin
scatter.txt
system.new.dat
system.patch.dat​
It does say I can use a recovery.img file from a similar tablet, but I do I know which tablet to use and where can I get it? Any ideas?

So, no ideas about how to get the recovery?
I found the recovery for the A3-A40, but MTK Droid Root & Tools complained that the size wasn't what it should be.

You should be able to port the A3-A40 TWRP to work on B3-A40.
Do a Google search for:
"Port TWRP Mtk"
That will give you lots of results with videos and guides to port TWRP on Mtk devices.

Fire HD8 8th Gen gets OS update to 6.3.1.2

I just now received the 6.3.1.2 OS on my 8th gen Fire HD 8. The build number is 1852.
It's still loading the update, so I don't know if it messes with my launcher hijack or not. Should know soon.
I think the main OS version is the same one that came on the recent 9th gen Fire 7 tablets.
Just thought I'd share. We'll see what happens.

What's new/working on Fire OS 6.3.1.2
On another Fire HD 8 we updated.

Does mtk-su still works? I didn't unlock my tablet yet, waiting to know if it still works for upgrading.

Not with latest FireOS build(s); vulnerability apparently blocked/patched. Can still unlock and root, just no temp root via mtk-su.

Can anyone catch this OTA Update and post the link?

Can someone test out if it's possible to downgrade to 6.3.0.1 via recovery without bricking? If it ends up not booting, you can recover it through the amonet+hardware method.

Can you block the internet access from OTA updates using NoRoot Firewall from Google Play Store
Can you also downgrade it the Fire OS 6.3.1.2 to 6.3.0.1 via ADB sideload without bricking (Wipe all the cache and data first, before downgrade it). If your Fire tablet gets boot-loop or bricking, Get solution: https://forum.xda-developers.com/hd...d-8-2018-downgrade-unlock-root-t3894256/page1

Typically VPN based firewalls (VPNs in general) do not function well on FireOS. Are you stating NoRoot Firewall operates correctly on FireOS v6 ... or simply speculating based on feature set?

Yea, he's posted the same thing in several threads w/o substantiation. I challenged the assertion in one thread but have yet to receive a response.
Might work, just need some evidence it doesn't yield a (soft) brick. Seems strange Amazon would tweak the bootloader given changes baked into 6.3.1.2 and above.

Just to confirm, downgrade to 6.3.0.1 is NOT POSSIBLE using stock recovery (It will result in a brick).
Code:
[4646] [ANTI-ROLLBACK] Processing anti-rollback data
[4650] mmc_rpmb_send_command -> req_type=0x1, type=0x4, blks=0x1
[4654] mmc_rpmb_send_command -> req_type=0x2, type=0x4, blks=0x1

LK-Version has been updated from 1 to 2. (TZ and PL remain at the same version)

Yeah, that makes sense, @k4y0z, because someone else reported getting a brick. This AmznUser guy, I suspect if he did try it, it was using TWRP. That's why I emphasized stock recovery...

I suspect he didn't try at all, since 6.3.1.2 can still be rooted fine using Magisk when unlocked, no downgrade necessary.
To be honest I don't understand most of what this guy is posting
