[HOW TO] Root Remix Mini

[Poeta]

I simply changed the code on installing root to direct to the update file. Which you get at jides website.

How do you do that? Can you share the changed update file?

How do you do that? Can you share the changed update file?

/dev/tty.usbserial 115200
mount -o rw,remount /
mount -o rw,remount /system
mkdir /tmp
cd /system/bin
ln -s busybox-smp unzip
cd /data/local/tmp
cp /mnt/usbhost/Storage01/UPDATE-SuperSU-v2.46.zip /data/local/tmp <- Double check zip's file name and try Storage02 if Storage01 does not work because it depends on which usb port you plug the flash drive in.
cp /mnt/usbhost/Storage01/update-binary /data/local/tmp

The red text was changed to represent the update file name

This use the uart port or USB port?

UART

In case if you have the 104 framing error:
Have your pins connected to booted Mini, then replug the USB converter and hit Connect in Coolterm

@unloseking2500
I think the above is worth adding to the OP. I almost gave up on this, because I thought it's Win 10 or my PL2032HX converter. Wasted quite some time as well

Other things worth mentioning is that you don't have to pry off the whole rubber to get access to the screws. You can just lift up the part where screw is and take it out.

Thanks for the guide!

Would there be a way from this terminal to write an image of the contents of the storage to a usb drive so we could get a dump of the OS, file system, etc then use that to flash onto other remix minis to give them root?

@garrlker
You mean using the data to make a flashable .zip for the stock recovery?
You could try that, but I never used the Mini recovery so it's hard to say.
If you know how Mini's recovery .zips should be structured, then I think it should be possible to root with a flashable package.
It still wouldn't require you to pull data from a rooted mini to get the flashable zip. You can always try flashing a supersu zip, but I doubt it will work.

 

[garrlker]

Hmm yeah I figured it was a long shot. I might look into once I get this thing working.

So far, I can read the serial out but i don't think it is sending my commands, or atleast when I type a command and send I'm not getting feedback. Typing reboot doesn't do a thing. I've made sure my TX and RX wires are both plugged in well, anything you recommend to try?

 

[Vioner]

What do you use for the connection? Which converter?
Did you follow all the steps showed in text and screenshots?

 

[garrlker]

Same converter that is in the original post.

I have some jumper pins that are a just barely too big to slide right in but I have shoved them into the pinholes on the remix mini with a small amount of force. They're in enough that they are standing on there own and I can move the mini around and they won't come out.

I followed the steps exactly.
When I type any linux command and send it I don't get an output, which leads me to believe my TX must not be hooked up, but I assume there is some handshake the converter must go through to start receiving bits.
So the TX would need to be hooked up.

If not then that would make sense, it's just displaying all bits of information that it receives and just thinks it's sending out input when it really isn't.

Any thoughts? I'm at a loss here.

Do you have everything in Coolterm set as described in OP - significant part quoted below:?

6a. Click Options -> Serial Port -> Hit "Re-Scan Serial Ports" so it detects the appropriate port for serial converter. Mine is COM3.

- To find out, go to Device Manager -> Ports

6b. Select the right port. Then change the setting as in the picture:

6c. Go to tab Terminal -> Select Line Mode.

6d. Hit OK.

7. Power Remix mini up (make sure this happens or you will get serial 103 or 104 error code)

I attached my serial converter exactly the same way by forcing jumper pins in the Mini's connector holes.

Remember you are supposed to attach Rx-Tx, Tx-Rx, not Rx-Rx, Tx-Tx.

If the connection is right, then you should get output from Mini. If you don't, hit disconnect in Coolterm, reconnect the USB cable in your PC and then hit connect.

Yeah, i attached them right and I get output from the Mini atleast. It just seems like my TX might not be working if anything.

If I type a command and send, the TX "light" on the bottom right of CoolTerm does like up for a split second. I don't know if it actually is able to tell if the data was sent or not, but it does light up.

 

[Vioner]

I understand that in Terminal settings you have Line mode selected?

If you send a "ls" command and it returns nothing then Mini definitely does not receive the transmission.
In that case, to make sure the connection is right, I can only recommend using a multimeter continuity test.
Put 1 test node at the Tx converter pin and 2nd node on the Rx Mini pin. Pin, not the cable/jumperwire.

 

[garrlker]

@Vioner, so I have my multimeter hooked up from serial TX -> Red Multimeter Node -> Black Multimeter Node -> Mini RX
When i write a command and hit send I am seeing a voltage spike(although it is negative somehow, im sure im hooking it up wrong).
If I send a big command you can see the multimeter spiking on voltage for seconds as coolterm sends it. But still, no command is giving me output.

If you want a picture let me know.

@garrlker
Looks like the connection is just fine, so I'm pretty clueless :/ Not an experienced serial port user either, so can't be of much help.
It's always worth to try with a different PC to rule out drivers issue.
My converter is PL2032HX - a counterfeit of ProLific's converter. I had a problem with drivers for it in Win 10 x64, but in the end it works just fine.
@unloseking2500 maybe you can be of help as the thread author and user of exact same serial converter as @garrlker

 

[garrlker]

@Vioner
I tried with 4 PCs so far, but no dice.

Regardless, thank you so much for your help. I really appreciate it.

 

[Cubinsan1111]

anyone try this on v2.0.626 ??????????????

 

[Vioner]

I did. The version doesn't matter.

 

[scotyard]

Stuck on same issue as in : https://forum.xda-developers.com/showpost.php?p=71160959&postcount=52 ; cant get root prompt.

Using 2102 serial converter. Have used same process on PC & MAC also different ports.

any advice ?

Saw a notification of UPDATE today while reboot (unsuccessful). A new update after a long time?
