[Q] HDMI, OTA Updates, Unlocked Bootload, etc - Asus Eee Pad Transformer Prime

Hello Everyone,
Just some general inquiries:
Right before I rooted and unlocked bootloader on my Prime I recieved an OTA update from ASUS. After the update installed, HDMI out stopped working.
Questions:
I suspect the OTA update corrupted software (likely the kernal which controls software and hardware interaction) which caused the HDMI out to stop working. I know what you thinking...Haven't I read the forums? Units were shipped with defective HDMI outs... I have to say, for 2 months I had no problems with HDMI, worked flawlessley everytime, I used it daily. The port does not wiggle at all, the MicroHDMI fits snuggly. I've tried 2 different cords, multiple TVS of different brands, but since the update there as been a no go (I know it was the update, because the prime was connected to HDMI and I was watching netflix, then installed the updated with the TV connected, and it no longer worked on reboot of the prime). Any Ideas? Is it possible a kernal update pushed VIA the OTA update from ASUS messed up the output of HDMI? I noticed that all custom ROMs have been based off of the Build Number 9.4.2.15 V2. There's even the stock build listed here, http://forum.xda-developers.com/showthread.php?t=1518462 but does anyone know where I can get a previous build (custom only obviously so as to not brick it), to download and install it to correct the problem?
The only other solutions I can think of that I have not yet tried:
-Install a custom Kernal, and hopefully it rectifies the corrupted Kernal (Not ideal, I prefer the stock kernal and if custom kernals are based off of the stock kernal from the current build, I doubt it will fix the issue). Anyone know where I can find a custom kernal based off of a previous build??
-If the HDMI hardware is faulty, are there licensed repair shops where I can pay to have the HDMI output replaced? I can't RMA, I've already rooted and unlocked my bootloader.
Thank you in advance, for any advice or insight you might be able to provide.
Wave.

Potential HDMI Hardware diffency workaround
Has anyone tried this as a hardware work around due to a faulty MicroHDMI port???
Example:
1.) Connect stock USB cord to prime VIA port
2.) Connect Male USB connected to Prime into a female USB converter to Female USB converter.
3.) Connect Male USB to MicroUSB Female converter adapter found
on ebay **Crasy expensive here but sure its cheap in China.
4.) Connect MicroMHL to HDMI adapter found here (Normally used on Galaxy Nexus) - again on ebay
5.) Connect MicroMHL to HDMI cable and work around faulty HDMI output on Transformer Prime for TV Out???
Anyone out there given this a try? I have orders awaiting arrival and plan to test. The way I see it, if the kernal on a standard release of IceCream Sandwich shows support, I think the same will be across platforms (tablets, phones, etc.) or simply require a new .aph which exhibits support...
I will report back as soon as I have confirmed or unconfirmed functionalty.
Wave.

add a USB male to X2 USB Female splitter in the mix, and bam you can charge while you use your TV.... Heh like I said, I will report back once I attempt this hypothesis...

Think outside the box... I.E. Your tablet

Or think within it. Its official, the build update to .15 for the prime effectively stopped my HDMI output from working. It seems that the update to .21 build released by the masters today corrected the issue.
Now that the problem has been identified (OTA Updates), has anybudy sourced the root of the issue in the Kernal to prevent these problems from recurring in future updates?
Just happy to be back in action. Sure I order a bunch of un-needed cords as illustrated above, but its still worth testing for those who actually have a damaged HDMI out. Again. once I have test the above alternative I will report back.
As for now... Back to watching Netflixs and playing games on my Transformer Prime - Yeeeeah!

Do you have a confirmed source which indicates .15 version broke HDMI?
I have the same HDMI issue. It was working with initial ICS firmware. After some ICS update it stopped working. All this time I was thinking it was hardware issue, so I got motherboard replaced. Service center provided a 4.0.1 firmware and HDMI worked with it. But it stopped working again when I put latest JB firmware on it (US_epad_user_10_4_2_15_UpdateLauncher.zip). So it certainly is a software issue.
But it seems that only few people are observing this.
I am going to service center tomorrow and confirm that the hardware is fine by flashing older version.

[Q]Galaxy s2 i9100 + bluetooth mouse. 2.3.5 breaks it. 2.3.6 fixes!

I just recently bought a white galaxy s2 from newegg. I have an MHL to HDMI cable incoming, and when I saw that you could use a mouse with the device, I was really excited.
link: I'm too new to post links, but search google for "magic mouse samsung s2" and the youtube link should pop up first.
However, even though I am able to pair a mouse (I've tried a magic mouse and a mini presentation Microsoft Bluetooth mouse so far) when it connects, it instantly disconnects... and it keeps doing that over and over.
Bluetooth is able to keep a connection with other devices, like a headset and transfer data over bluetooth to my computer.
When I called Samsung support, first the girl didn't know connecting to a mouse was possible, and upon seeing the video, her response was why would I ever want to do that, and there was nothing she could do to help.
I saw other threads mentioning bluetooth problems could be fixed with a factory reset, but after doing so I have identical behavior. I don't think its a hardware issue, and I applied the newest update 2.3.5... I'm really confused here. What should I do? Any other details required? Maybe my magic mouse just doesn't like my phone?
From what I have heard apple magic mouse does not connect correctly.do you or a friend have a different bt mouse to test?

I have now tested the Bluetooth with a Logitech lazer Bluetooth mouse, in addition to the magic mouse and Microsoft mouse, with the same results. Does anyone else have this problem? Could the mouse HID been disabled by Samsung? or should I do a hardware warantee exchange?
Sent from my GT-I9100 using XDA App
I bought a cheap (8€) noname bluetooth mouse from amazon and it works perfectly on the Galaxy S2 on the stock rom, it also works on my Galaxy S running CM7.
Are you sure you have set your mouse to pairing mode?
(I had to press the connect button for 5 seconds)
I'm sure it's pairing. I press and hold connect on the mouse until it becomes visible to my galaxy s2. It ends up showing up as paired after I tap, but when I tap again, it only connects for a second (enough that the options for that device now show me HID) but it just drops immediately. But perhaps these mice with special buttons (like the Microsoft presentation mouse) and apple mice, and the Logitech mouse, are all beyond the scope of running on the phone.
I bought a super basic and cheap bluetooth mouse ($15 cdn) from amazon, it should arrive in 1-2 weeks. I'll follow up with this then. If the phone can't connect to that, I'm going to call Samsung and ask for a hardware exchange.
Also, I may be able to get my hands on a USB host cable, to see if i can get any mouse period working.
I really can't imagine it being faulty hardware though, considering all other Bluetooth functions work? or am I incorrect in assuming that?
So I decided to see what happens with a Bluetooth keyboard, and indeed I get the same result, connecting for a second then dropping.
I'm going to exchange my unit for a new one, hopefully that solves the issue. I'm getting paranoid that something is different with the white galaxy s2, can someone extinguish those fears for me?
Sent from my GT-I9100 using XDA App
Alright, follow up post. The new phone connects to mice/keyboards fine. It is current on 2.3.3. Could someone with an updated 2.3.5 s2 just confirm that the feature still works after update?
Edit: Ok, i let me phone upgrade from 2.3.3 to 2.3.5, and nothing can pair once again. Wow. Did Sammy really remove this functionality?
Final edit: Flash stock 2.3.6, and mouse will work again. So to recap, 2.3.3 good, 2.3.6 good, 2.3.5 bad
I have an Apple Mighty Mouse which work fine with my SGS1. It doesn't connect to SGS2. Same issue, the connection drops out after a second. My SGS2 is running on 2.3.6 Batista ROM with Siyah 2.3 kernel.
HID Bluetooth killed by 2.3.5 upgrade
Hi, I think I have a good picture of what has happened having trawlled the net looking for answers. In summary:
2.3.3 and 2.3.4 supported and worked with bluetooth HID devices (like my sandberg mini bluetooth keyboard).
2.3.5 as suggested by Samsung key's had issues with bluetooth from the start. It all looked good until you turned bluetooth on then it went into a FREEZE, BLACK SCREEN, LOCK SCREEN cycle with a 20-30 second window at best to try and turn bluetooth off once you realised it, repeating "ad infinitum".
Some folks found that a factory reset cured this. I got a replacement from Otrange UK after a lengthy discussion!
BUT however you may have fixed this is seems that any bluetooth HID device (Mouse, Keyboard) will not stay connected against 2.3.5. They pair ok, they even actually connect for a fraction of a second then bomb out again.
I just spoke to Orange UK Tech who in turn spoke to Samsung who said they were "Not aware" of the issue but would "Escalate a resolution" and get back to me. 2.3.6 is supposedly about to come out for Orange UK within "2 Months" and will contain a fix. Apparently. Looking at other stuff, 2.3.6 does appear to be the best hope.
They confirmed something though; 2.3.5 back to 2.3.3 / 2.3.4 is not supported/advised/safe so waiting for the new version is the only hope.
All this, so the lists won't bounce a'la APPLE and have a blue "bottom of list" flash instead... Ok, maybe there was some good stuff in the rom but it's kinda been overshadowed for me
Good luck out there and hold on to your hope!
I heard back from Samsung support today (Orange having referred my case).
They said that their 2.3.5 was new (erm, yes) and that it wasn't backwards compatible, and for any devices that no longer worked I would have to get that devices supplier to provide new software on that device.
They used a car kit as an example.
So I specifically asked "Are you saying you released an update without any warning, that would render all previosuly compatible bluetooth HID hardware incompatible?" And he answered that this was the case and that I would have to ask Sandberg to update my device so that it would connect to 2.3.5
Now, either he had absolutely no idea what he was talking about, or there is something very wrong at Samsung.
I have asked for him to confirm this to me in an email. (I intend to make use of this writen statement if it confirms the above conversation.)
Has anyone else ever heard anything so bizzarre?
I surely hope this can't be right!

[Q] Anyone having issues with HDMI out post .15 update

So, I haven't had any problems with my TFP until now. My HDMI out port was working just fine about a week ago then I tried it yesterday and it completely does not work. I'm not sure if this is due to the .15 update (it could be hardware failure), but I wanted to know if anyone else is having issues with their HDMI out port.
Keep in mind I tested both the HDMI port on my TV and the cord and both are fine. I plan on taking it back for an exchange today as it's my last day to do this, unless somebody knows for sure it's a software problem. I got it at best buy so that means a refund and I get to go back and troll the website until they get some in.
Nope...Mine working fine.
Thanks for the response! I now think my problem was likely hardware and the port for whatever reason just stopped working. I already returned it to BB and am now trolling for another....again...

[Q] XXLPQ ROM with working MHL

Hi,
the MHL HDMI output is very important for me. Does someone know if the new XXLPQ Roms support MHL?
regards
Andre
I just tried with mine, first time kernel panicked, I had siyah b06 kernel flashed.
I then flashed the stock kernel, tried kernel didn't panic however my TV just gave the following output: unsupported signal.
So my guess is NO.
However this could be that I have a faulty MHL cable though.
Can anyone verify this ?
I got nothing on my tv. Original cable, charge function works just fine though. I'm running XWLP2-CL258785 [email protected] #3. I don't get it. I even tried it with 2.3.6, no result either. I'm pretty pissed.
I just want to hook it up to my tv and use a BT Mouse as a controller (mouse doesn't work properly eiter). Thinks this firmware is not so good as i thought.
I will try it with a friends phone (HTC Sensation XE) later this week just to be shure. If i don't get any image eiter maybe the cable is broken.
I doubt that your cable and mine are faulty what are the odds ?
Anyways let me know when you try on your friend's sensation.

HDMI not working, RMA?

My hdmi port isn't working anymore and google tells me its a motherboard issue and that I should send it in,
however I am rooted with cm10. Should I unroot and flash stock before I sent it in?

you should check to see if its an issue with your rom. not all roms have functioning hdmi

That's what i thought of first (even though it would've been weird for it to just stop working), so I tried another rom but it still didn't work.
When I plug it in, I no longer get the hdmi notification also the cable feels loose in the port.
Just wanted to know if I should unroot and stuff for the rma (if it goes through).
Try flashing different rom
Edit: you just answered it. If you are u locked you'll probably have to pay for the repair...

i had same issue, but the fault was with the micro-hdmi to hdmi adapter...
try another adapter or a direct cable, before you RMA or before you install new rom

[PX5] MCTE - Any possible low temperature fix? WiFi/USB issues below 0°C!

Hi there,
At 4pda, they are writing, that some PX5 units have troubles with WiFi/USB below 0°C.
It looks like my Witson unit (MX2 MCU, PX5, Android 8) suffers from exactly this problem. The last days we had warm temperature and USB and WiFi worked perfectly.
Now I went outside and the issues are back. It's 0°C now here!
Can anyone confirm this issue?
At 4PDA, they suggest a fix by adding a screw-whole + screw to better fix the proccessor unit:
https://4pda.ru/forum/index.php?s=&showtopic=883219&view=findpost&p=77467642
It looks like the processor unit is only fixed by 2 and not 3 screws and especially the two most outside pins, which are responsible for wifi and usb suffer from loosing contact with cold temperature.
I'm keen on trying to hardware fix. But I'd like to know if someone has experience with this?
Christian
Seems like a easy issue to check for and then apply if your unit has this issue. You might help others by testing the solution and posting result/images.

I now read the whole post in an ugly into german translated version.
The theory with the processor unit is not confirmed, the people over there discuss about powering issues for the usb ports, temperature-related problems etc. No finally confirmed fix seems availbale yet.
As my unit is less than two weeks old, I am claiming warranty. At least I purchased trough an UK dealer with paypal, so first I hope for a replacement.
If I don't make progress with that, I'll open the unit and look for the issue.
If someone elso would have a confirmed working fix, I'd try it.

There's another thread where a few of us have been researching this problem. The fix is posted HERE. There's no need to open the unit.
There's links in that thread to the 4pda forums where they explain what the issue is also. Long story short, it ends up being a manufacturing defect relating to the USB host controller. Newer versions of the board don't have this problem. But I can confirm the above fix does work like a charm, I've tested it several times.

Hi there, will comment in the thread you linked. I have running that fix with tasker already but still have partial drops of the host controller. I'm also working on a tasker task to switch WiFi on as soon as it gets off.

If anyone is still interested in a hardware fix, my KSP units have a 5-pin IC for USB current limiting and I found if the part is cooled, the USB will not turn on when it wakes up. I replaced one with a TPS2001DDBVT, same package and pinout but better specs. It passed the bench test. I haven't gotten around to installing the HU yet.
Update: I installed the unit with replaced ic, and it behaved differently, though not yet correctly.
It's worth noting, a Dasaita HU which has not exhibited the low-temperature wifi issue has the same USB hub chip, but a different (much larger) crystal attached.
I installed the newer usb hub chip as mentioned in the other thread. No more low temperature problems, however if I reboot the unit via software (with a rooted app), the wifi does not come on. One must reboot with the reset hole. Do not try this while driving.

Hello
Can you make a photo of crystal and send it here?
Dasaita change something in board design (usb hub for sure) and currently doesn't exhibit cold temp bug.
Info confirmed with my friend with new unit.
I have older unit (from September) with older usb hub and need to make an upgrade.

Thanks for the info and question, I will send a picture, I can also compare to an earlier model, that's much easier than trying to trace the current circuit.

Hi
I have the same problem on my Dasaita bought on september 2018!
which upgrade do you suggest? hardware or software?
the problem occurs only with the dab module connected to the cable with 2 usb, while the single USB cable, which I connected the 4G wi-fi router, always works.
If I will installed the hal9k ROM, could I fix the problem?
thanks

I'm going for HW repair. I've ordered GL852 sop28 from ALiexp (0,55+3,4USD shipping).
Dasaita knows about problem with GL850, but they proposed to replace chip by myself or to send them SOM board and wait till they resend it back. well, i'm definitelly not happy with their response.
I hope that replacing USB hub will solve at least one other problem - random unmounting usb drives and problems with copying files from usb to sd-card.

You need to open-up your HU to check. Also there is a thread on xda regardig WiFi/BT issues;

Ok. I'm going to check the chip model.
I haven't problems with the Wi-Fi or BT.
when the temperature is low the DAB module connected to the double USB cable doesn't work, everything else are fine.
could I have your same problem?
I changed the gl850 ssop28 with the better version gl852g. Now I have no real problems anymore with my xrc unit. There is a software fix in hal9k 3.1.1 in the mod settings but it was only working when it was not to cold. I had in cold days allway to wait and reboot the system ...

No, it's not really easy, but without no skills before I did it. I just watch some desoldering and soldering videos and tried a bit with an littel another broken board with a ssop8 socket on it. I desoldered a lot and soldered a lot on it and then I change the chip on my mainboard.

I used a soldering iron beacuse I din't had a hot air station.
