[Q] Rooted a501 hdmi not detecting

Hi,
I've tried searching for this but I have found no solution. I'm a newbie that has rooted an A501,
Followed all the instructions and it has been working perfectly, but now my HDMI is not responding at all on my tablet. I plug in the cable and its not detected. I used a custom rom Alexandra lll. The cable is fine, it works on my wife's a500(not rooted).
Any help would be greatly appreciated

I'm using kernel 2.6.36.3HoneyVillian-3.4+, and rom Alexandra III Rev 1.1, if that helps at all.
UPDATE:
Turns out that it's a faulty connection on my device. I've been searching for hours and nobody else has had this issue.

I need Signed Stock/Any Firmware ZIP

Hello all,
I need to help a friend with his Note 4 N910W. The devices has some software issues but has a bad USB. Can not be flashed with Odin.
Already replaced the complete Charging port Flex/Module but still not connecting to PC for data. It doesn't also fast charge as I believe it uses the data pin to detect the charger plugged in.
I have tried rooting without pc then flashing a custom rom but can't find a rooting method.
Can anyone help or point to where a can get a ROM/FIRMWARE which is signed and can flash via the Stock Android Recovery cos I think it's the only next thing that can work.
Thanks.

Really Tricky Problem

Hello people!
I've been doing installation of custom ROM and any kind of configuration for a while now. But I have now in my hands a tough problem. My dad bought athene XT1640-DS (Moto G4 Plus), just like the one of mine own, but mine doesn't have the '-DS'.
But the device is stuck at Stock Android 6.0.1 and I can't update it.
The USB seems have some problem because any PC in my house recognize the 6.0.1 phone, but works fine with my up to date 8.1.0 athene, but it's charging only, and the turbo charging isn't working. the fingerprint isn't working neither.
It looks like the bootloader was unlooked, because everytime it's turned on shows the 'bootloarder unlock message'. But I was unable to root it, I tried all the one click root apps, but none of them worked.
It doesn't have any custom recovery, so I tried to update with the stock recovery but every OTA Blur Version rom that I found for athene shows a error telling that my ROM version isn't compatible with the updates (the ROM version code of this phone is MPJ24.139-23.1/ 1 user).
Anyone have any hints of what can I do to update this device?
Device XT-1640-DS
Android: 6.0.1
M8952_7000.04.03.32R
ATHENE_BRAZIL_DSDS_CUST
Kernel: 3.10.84-GCF01273

MPJ23.139-23.1
From what I know one click methods doesn't work with this device. You need a proper kernel for android 6.0 like elementalx 1.0. And supersu or magisk zip flashed through a recovery like TWRP.
Is there a way to update de kernel, or do that other things without PC and root?
Or a way to use adb without USB connection?
Have you tried fastboot flash methods like in this thread?

So.. the big issue is that this device isn't connecting to the PC, it's charges, but neither the PC not the Android show any signs that their are connected. I can't use adb from the PC because I couldn't make the computer recognize the phone.
can you at least transfer files in mtp mode with the usb cable? because looks like the micro usb port is messed up.
If you are on warranty period you should go for it
I can't use the mtp neither. The only thing I can do is charge. And I'm out of warranty :/
