Noobie Question

Hiya Vamp, I'm having a bit of a noobie problem here. In a nut-shell I can't get my fastboot tool to detect the tablet. However adb can detect it. After some quick research I found out I needed to write a udev rules file, which I did; I ran a lsusb command to get the hex id for the device. I also tried using sudo with no effect. My OS is Kubuntu 14.04 64bit, I have the 32bit libraries installed. I've never rooted a device before besides using "poot" on my old phone and I don’t even know if that really counts.

here is a quick copy of my /etc/udev/rules.d/51-android.rules file:

SUBSYSTEM=="usb", ATTRS{idVendor}=="04f2", MODE="0666"
SUBSYSTEM=="usb", ATTRS{idVendor}=="8087", MODE="0666"
SUBSYSTEM=="usb", ATTRS{idVendor}=="04e8", MODE="0666"

Here is the output from adb devices:

List of devices attached
YFGV0415004049 device

The output from either sudo fastboot devices or fastboot devices is nothing, the terminal gives no errors or other kind of output; it simply displays a new prompt.

And this is the output from the lsusb command:

Bus 001 Device 002: ID 04f2:b008 Chicony Electronics Co., Ltd USB 2.0 Camera
Bus 001 Device 013: ID 8087:0a5f Intel Corp.

Invoking the adb reboot bootloader command will reboot the device and it says "fastboot cmd waiting..." yet I still get the same output from the above commands, with or without using sudo. Anyway I'm at my wits end on this and hopefully you can point me in the right direction. :confused:

Are you using the fastboot binary I provided?
[Android Q&A, Help & Troubleshooting] Beef-Supreme:
No I think I'm using the one I installed from the ppa repositories. How do I get rid of it and use yours? Can I just overwrite the existing one in my sdk/platform-tools folder with yours?
[Android Q&A, Help & Troubleshooting] vampirefo:
To use mine simply open terminal in folder where you extracted my files, then sudo ./fastboot devices

---------- Post added at 06:42 PM ---------- Previous post was at 06:41 PM ----------

./ tells terminal to use local fastboot binary which in this case will be mine.
[Android Q&A, Help & Troubleshooting] Beef-Supreme:
Works!

Awesome! You are a gentleman and a scholar good sir :) Yours is detecting it, and now I have it rooted and that silly encryption gone! Super easy when you use the right binary lol. Thanks for your help boss, I'm going to have allot of fun with this tablet thanks to you. How do you make your own custom tools? Do you code them in Java like most android apps? Or is it written in C? I'm still somewhat new to programming but my snake game should be bad ass on this tablet. Anyway thanks Vamp! :highfive:

As a side question: Does/did your tablet open apps and do other random things without any input when its plugged into a computer via usb cable? Mine just randomly went to the brightness setting for the display without me touching it, kinda strange, it was doing the same thing before root so I don’t think it's a problem with any data installed during the root process.

No, but there is a reported memory leak with lollipop 5, so some of us are using xposed with memory patch.

Most of my tools are compiled using cm12 source.
[Android Q&A, Help & Troubleshooting] Dirtydarko:
I just want to say for the record that I followed your directions perfectly and rooted my tablet and installed the recovery without a problem. Now I'm running an unencrypted stock rooted lollipop ROM with the latest TWRP recovery and honestly I couldn't ask for more! (Maybe CM12.1 if i'm being greedy). Thank you so much! I don't know what's wrong with everyone else. If anyone needs me to, I can upload a twrp backup or something. I'm more than willing to help in any way that I can. I basically consider myself a noob, and following your instructions was not a problem, I actually even used windows and it wasn't a problem at all.

Another silly question

@vampirefo:

The adb.exe binary I downloaded from this thread:

http://xdaforums.com/showthread.php?t=3126306

Will not detect the tablet, but my stock adb detects it just fine. My question is can I push the files to the tablet and install them with my stock adb, or is there something special about the adb binary provided in the .zip file that requires its use?

@mrdyang23:

If you're using windows you'll need to download the Google USB Driver before adb will detect anything:

https://developer.android.com/sdk/win-usb.html

Also make sure to enable usb-debugging on the device (I've made this mistake before and felt silly afterwards).

I know nothing about a adb.exe that is a windows file, I use Linux.

Just use your own adb.

Thanks again :)

Woot de woot! Manually pushing the files and running the installer worked fine with my Linux adb. Don't mind me I've never really done much with androids besides making pixels move around on the screen. Rooting and Xposed are all entirely new to me. Thanks Vampy :)

[Android Q&A, Help & Troubleshooting] Beef-Supreme:
Way smoother

It feels a lot smoother after unencrypting plus android studio now works much faster with the tablet too. Also the battery lasts longer since the processor isn't wasting time with an encrypted file system.

Can you tell me if GPS is working on your Ares 8 tablet? I just hooked one up from Walmart for the sole purpose of running Nokia Here maps in offline mode. Here worked great last week in no-data situations in the northern tip of WI from my Nexus6. But Nokia Here, Google Maps, and several GPS calibration apps cannot get a GPS lock on this tablet. Only time I got a location was using wifi location. I wiped aGPS data, tried to download new aGPS data, etc. The GPS sensor appears to become active in the status bar but nothing happens. Guess I make it a picture frame or take it back unless someone tells me I got a lemon and should try another one??? Thanks.

This tablet doesn't have GPS, it can use wifi to get location, it can't detect satellites.

From Windows 7 Computer

Windows 7 Just a little different than linux here is what i did different.

I downloaded and unzipped the file from the previous post leaving twrp_recovery.img file in the c:\.

I still put the remove_encryption.zip, and SuperSU246.zip on sd card.

Then:

Just go to the Start menu type cmd in the search box and right click it and run as administrator.

Run the commands in the same order that the previous post shows.

adb reboot bootloader

Just change this command "sudo ./fastboot flash recovery ./twrp_recovery.img"

TO:

fastboot flash recovery C:\twrp_recovery.img

Then follow the rest of his direction in the post.

Hello, great work, vampirefo, making NXA8QC116 rooted.

I'm completely new to Android and rooting and I'd like to ask few question (that I've trying to answer myself, but I have still some doubts).

1- I need to use twrp recovery to install remove_encryption and supersu because the original recovery does not allow this. Am I right?

2- When someones installs remove_encryption what exactly happens?

3- When someones installs supersu what exactly happens?

4- With the previous steps, does the table have root access and the encryption has been removed?

5- Why do I need to flash boot with another boot.img different than the original?

6- How could I get a backup (using fastboot or adb or something else) of the table's original boot.img and recovery.img (I mean the original recovery and boot partitions)?

7- Which of the uploaded files should I use follow the vampirefo's instructions (NXA8QC116_root_kit.zip or boot_recovery_ares8.zip or root_twrp_remove_encryption.zip)?

Sorry, I bother you, guys, with my very noob questions, but I really need to understand what is happening in the rooting process.

Thanks you very much in advance.
[Android Q&A, Help & Troubleshooting] zerozed99:
Vampirefo most likely will not answer you [MENTION=6903011]silviodelgado70[/MENTION] and if he does, it probably won't be very polite. I 100% appreciate you wanting to know the basics, but devs generally don't have the time or patience to educate people on the fundamentals of Android. I'd recommend you just do some google searches on Android rooting in general--that will give you the answers you're looking for probably. I'm not trying to be rude, but I doubted you'd get any reply to your questions, so I figured I should probably tell you why.

I'm not going to answer your questions one by one, but here's the bottom line....when you purchased your tablet you did not have "root" access or a custom recovery. Without root access you cannot make substantive changes to the OS. The Ares 8 had decryption turned on by default with no ability to turn it off. To turn off the decryption, you need to be able to flash stuff via recovery, but to do that, you need a custom recovery (in this case TWRP). So that's what this system provides...flashing a custom recovery, which in turn allows you to flash a boot image not hampered by encryption, and finally the ability to install SU so you'll have root access. Once you have TWRP installed you can just do a nandroid backup from within TWRP thus allowing you to restore the tablet to whatever configuration you've backed up.
[Android Q&A, Help & Troubleshooting] silviodelgado70:
Thanks you very much, zerozed99, for your quick response. I'm so glad to know this forums has very gently people.

Ok, I did very large reading in the Internet before asking my questions. I did not found good answers. If anyone knows a link to something that might be useful, please, let me know.

Well, to do the procedure I will not wait to know all the details that I asked. So what I need is only the answers to the last two questions.

I mean, how do I get the backup images to recover my tablet if something goes wrong?

What files should I use to follow vampirefo's instructions (NXA8QC116_root_kit.zip or boot_recovery_ares8.zip or root_twrp_remove_encryption.zip)?
[Android Q&A, Help & Troubleshooting] theWolfTamer:
I finally rooted mine after a couple of months. I just wish I got the deoxed version. I didn't have any issues once I opened terminal in the right place. Just wanted to say thanks.
[Android Q&A, Help & Troubleshooting] silviodelgado70:
I successfully rooted my NXA8QC116 thanks to vampirefo instructions. But since then I have noted that after some time my tablet is turned on, the games are slowed down. I mean, they have very high fps when it is recently turned on but later the fps falls very much. I run antutu benchmark and the same happens (very high score when recently turned on and very low score sometime after turned on).

I’m completely sure it was not happening before rooting. Anyone knows why is this happening? How could I fix it? Can anyone give me a link to original boot.img and system.img (just to check if it’s a problem of my system)?

Thanks anyway.

This is common for any 5.0, this version has a memory leak, as noted by google, the only real fix is upgrade to 5.1 however 5.1 isn't available for this tablet.

Only option available is to install xposed then install memory leak fixed. The memory leak fix works well enough, 5.1 would be a permanent fix.

ok I don't see an easy way to edit my post up there, and I am out of time. I tried wiping data/cache from twrp, it gave a mounting error. I could use format... but it looked scary and for all I know that's how people are bricking. Your instructions say:

"in stock recovery

format /data and /cache, reboot to bootloader "

Ok well after we have twrp, how do we get to stock recovery to do this?

Wow, no one, really? I was able to do this from TWRP after flashing remove_encryption, a step that isn't present in one of the guides in the OP, but is in another.

Most of my problems are driver related. Most the time fastboot or adb or both would not recognize my device, no matter what drivers I tried to install.

The rest could have taken 5 minutes if a couple things made a little more sense. This is my 4th or 5th device I've rooted including nexus prime, htc incredible, kindle fire (original), and fire phone. I'm not exactly a noob.

I do not have this tab atm but I am thinking of getting it because of the price but don't want all the greaf that comes with it so I am very interested in doing all the work to get it working at its fullest potential. Anyone else's help is also appreciated. I understand how to download and extract the files and placing certain ones one an sd card. I'm assuming I would have the tablet plugged into my computer and using the terminal to do the commands is this correct? Right now my computer doesn't even recognize the files and won't run anything. I am trying things on my own but there are quite a few blanks I am unaware of and can only possibly find them through trial and error. Hopefully not so much error. Again I need to use windows if this is possible. Thank you all in advance for your help and patience. Also there may be some of these blanks mentioned in this thread but beyond my comprehension at this point. It might also all be clear once I get the tablet and hook everything up but I haven't convinced myself yet to even buying it but it seems to be the best deal atm. lol, maybe I can practice on my cellphone which I recently had to do a full reinstall.
