[Q] MHL troubleshoot - Sprint Samsung Galaxy Note II

Got a cheap knockoff mhl. Ive been stock and only rooted. It worked completely fine for a good couple months until I stupidly accepted then MA7 update. It inevitably crashed while updating android software and now MHL to HDMI shows "HDMI connected" then instantaneously shows "HDMI disconnected" repeatedly, with no connection whatsoever. I flashed the MA7 firmware and modem, then flashed the deodexed version to reinstall the software and the cable still has the same results. Is there any way I can fix this without buying the samsung cable [ROMS, resets, cut and paste system files, etc]....?

I found that the only MHL adapter that works reliably is the one from Samsung. I've tried several others... Half don't work at all, and the other half are real buggy. I got the Samsung adapter and it works great.

I don't know if I've tried the MHL adapter on MA7. I'll try it later when I have more time.
I don't like the fact that your GN2 crashed when updating. It may be more prudent to do a wipe cache, davick, and system and reflash your firmware.
It sounds like you may have a short in your MHL setup--HDMI cable, adapter, etc. I've had it happen to me, and it was usually a loose connection somewhere between the MHL adapter, hdmi cable, or 5-11pin adapter.

I tested out the HML on my GN2 that is a MA7 deoxidized stock rom. It worked fine for me. Below is a video as proof.
I'm running Perseus kernel from March 3, Alpha 33. Beyond it's all mostly generic monoprice stuff--hml adapter, hdmi cable, 5-11pin microUSB adapter--and the USB charger and cable that came with the phone.

i tried custom roms...
one of them is 2.3.5 and the other one is 2.3.4
the two devices are rooted
I have the OEM Samsung adapter and it used to make my phone do the same thing. I sold the phone ans ended up buying another one and the second phone works perfect with it.
I am running the leomar75 rom with the ragemod 1.1b kernel
so you say this is a problem with the device itself?
I also have a generic adapter but mine works for a few seconds and then blank.....not supported. sometimes it gives green screen on my tv. I've tried on stock and custom roms. If it's the phone than it should be addressed t Samsung.
update:
I have to put my phone in offline mode to be able to use it.....
i tried the same cable on other tv...
on the other tv the phone signal stayed on (and i even received a call without any problem) but i still had no WIFI...
maybe its important, but i tried the other tv away from home..
at my home the phone signal is weak all the time
i have a stock phone w/ generic POWERED mhl cable and the wifi cuts off when plugged in. wth?
still no fix for this issue?? i just got a MHL cable yesterday and is really annoying
I called samsung and they said that it is designed to cut off wifi. it may look like u r still connected, but u will be unable to surf the net. they said the reason this was done was to prevent fickering of the video if you were browsing the net or something.
so ,there's no hope than MHL work with wifi?

dont ask me. call samsung. just telling u what they told me. the way it is designed wifi is shut off when mhl cables are used.
would be interesting to see if anyone got wifi to work w/ mhl plugged in.

I have had WIFI working with MHL connected for months. I've could surf the web AND stream flash videos in a room with GPRS coverage ONLY (which rules out the "you were surfing through packet data" variable) while connected to my Samsung HD plasma with no problems.
So I certainly have no idea what your Sammy rep was talking about.
BTW, I'm using the official, korean spec MHL cables I got from ExportPrive. But I'm positive it should work the same with the international MHL cables.
Bought a non Samsung MHL cable today and it worked perfectly fine, it even worked when providing power via a microUSB cable connected from a spare USB socket in my nearby router.
Another user on a forum I frequent has similar issues with WiFi dropping and had this solution:

Another OcUK user
My MHL problem is fixed now, i tested it for 15 minutes and wifi and gsm signal were fine
I was just about to post it in this thread and then saw your post haha
IF anyone decides to mess about with chargers/adapters with higher currents then do it at your own risk and read up if its ok to do so with your phone etc..!
I try with my nokia N900 charger and still nothing, I'm using the official MHL cable

Rom/kernel issue?
I'm using a Nokia AC10X (1200ma charger) + original MHL cable + Siyah 2.1rc2 (at that time, now running 2.1.1) + VR2.4.2 (don't ask) = no connection issues what so ever while in HDMI out.
Either that or it's a hardware problem with the cable or your phone.

[Q] CM10 - USB OTG / Keyboard

I'm trying to use a keyboard with my nexus for ssh. I have CM10 nightly (over a week old, updating now.)
I have not seen much talk so I assume that it works? I can't get it to work, but it might be the adapter that I have. I'm using a short usb conversion cable and a female to female adapter in the middle.
Thanks,

This is a Logitech cheapo 101 key. I can't believe it wouldn't work if others work. I can't get storage or anything to work. not certain but I'm thinking it's my adapter.
Similar problem here, and i'm pretty sure it's not the adapter because I tried it -and the same keyboard- on a Galaxy Tab 3110 with the stock Samsung ROM, works fine. I have the 3100 (same thing plus GSM) and it will not see the keyboard either on CM9 or CM10, so I'm even considering going back to the Samsung ROM :s

[Q] Note 2 MHL / CWM 6

Hey all
Just bought the MHL adopter. I had omega v9.1 installed on my note 2 and the MHL did not work with that. Then I installed stock ROM and MHL started to work.
Then I rooted my phone with cwm 6 and now when I connect MHL, I only get a notification HDMI connected but no image. Is there anyone here who is using MHL adopter with note 2 and his/her phone is rooted or has a custom ROM. Any help would be appreciated.
My infuse didnt work after 2.2 with the hdmi adapter lol.
I douvt its cwm6 but rather your rom is most likely the culprit. But you say you're on stock.
Can you try a different tv? Since hdmi is a handshake thing.

Alot of issues with the mhl adapter. I just went to th3 sprint store to see a friend and get info about my phone and found out alot of mhl adapters are knock offs. Some say samsung and come from china but they dont work and if u place the product next to the real deal product ya see there r several differences. Some try to save a buck but end up with a headache due to the knock off not working.lol go to your local dealer or samsung and b happy

Some people have issues with the port on the phone from being rough and shoving plug in b gentle and it will work fine and last. To make sure its not the phone itself go to a store and have em look at it its free.if nothing wrong with the port u need the right mhl cord .sprint has the wireless adapter for note ii to connect to television

So the problem is the root...
I'm rooted with a mhl adapter and it works. This may sound crazy but have you tried resetting the ROM counter using triangle away?

[Q] OTG intermittently recognized on stock FW

Can someone please help me with this issue. My phone (SGH-M919) doesn't have any working issues, except when I plug an OTG cable in, "most of the time" the phone won't recognize it. I can go a couple of days plugging it in without it working, and then one day it will just work all day. I've tried doing a reset. I've also used Kies to reinstall the firmware and none of those things seem to work. I originally used odin as well and that didn't work. I know it's not the cable because I've tried 5 different ones and they all work on my wife's S4. Any help will be much appreciated.
First assumption is bad otg cable.

Thanks for the reply, but as stated all cables work fine in wife's S4. I'm experiencing the issue at this moment. Cable started working immediately after posting this problem, just a few minutes ago (@ 10 hours later) it stopped working "again"! Considering an exchange.

Root/Knox and MHL HDMI

I have had a Note 2 for a few years along with an MHL cable. When I first got the phone, this worked perfectly to show on the TV.
I forgot about the cable for a few years, but now when I try to use it, it does not work, nothing on screen, the only thing that happens is the phone charges.
The only difference I see from before is that Knox has been tripped. I've always had my phone rooted and it worked before, but maybe something Knox has done? I tried the 'Screen Mirroring' fix on another thread but no luck.
Tried many different TW Roms and 2 compatible MHL cables.
Is anyone else experiencing this problem and does anyone have a solution?
Noticed it too, had to upgrade from 4.1 for software and can't get the mhl/hdmi to work yet.
