TEST: Fix Flickering Screen And All Other Issues

I have an idea, that I'm willing to test. This is my first post in the Dev Section, so go easy on me if I have made any mistakes.
I'm sure many of you are aware of the issues with the One X, Flickering, Glitchy UI etc. So, I came up with a idea -
I have 2 HTC One X in my possession, one works flawlessly but has a Yellow screen (Because it is possibly made by Sharp), the other which is my first one, has flickering and every problem you can imagine.
So, If I was to get the ROM from my working Yellow screen One X, onto my first One X, is it possible that this would stop all the problems AND work on the clearer screen (possibly made by Acer)?
I'm willing to test it. But my time is running out. Both phones are due back within 3 weeks now as I've filed for a refund from Amazon. And before I do this, will it stop me from getting a refund? Regardless, the phones have issues (I guess the yellow screen is not a bug, but it is not the phone I purchased - if you get me).
So, what do I do? How do I dump my ROM, and how do I get it on my first One X?
All I know is to unlock them both on htcdev.com, but rooting and getting Clockwork/xRecovery (whatever it's name is now), I haven't got a clue. I've done it with all my other devices (around 6 or 7), but this is a different kettle of fish.
Thanks!

Are you assuming the screens are made by Sharp or Acer as they are the suppliers HTC chose for the Sensation?

Yeah, it's just an assumption. It's very probable.

I don't know if it's possible to return an unlocked phone, because unlocking the phone voids some parts of the warranty. But i believe that there's a way to return the phone to it's locked state by re-locking and flashing the stock RUU, but i haven't tried it, and i don't know if it's possible to do with the one X.

You really think the phones have different ROMs? Because that's what you are suggesting, and in that case there would be different RRU's also. And also a clean RRU install would fix the flicker in that case, which I'm sure it doesn't.. And also, I think the screens are made by Samsung, but I'm not sure. The few I've tested have had the same panel ID even though one is warmer (yellower) than the other.
And lastly, you won't be able to return it if you've unlocked it though htcdev.com.. Maybe, if your lucky they don't check, you could re-lock it and hope for the best. But I guess Amazon know's what to look for. You better leave the dev'ing to the devs.

Your right. Not unless the FW is stored on a server and somehow is locked to you when you download the FW for reinstall. I'll give this a shot. I'm back on Ubuntu now, so I'm not 100% sure how to update my HTC using it... I'll look.

Check the software version number, if it's the same then there is no benefit to "copying" the rom from one to the other.

I just thought it might be worth a shot. No one seems to have an answer as to why the screen flickers. I'm just trying to narrow what could be wrong down by doing tests.

The answer is most probably faulty hardware, I've tried loads of roms not one fixes the flicker, mine gets replaced Monday.

It's surely not software. Maybe if the nand is broken and your screen drivers just happens to be at the bad blocks every time (and don't get remapped) No, don't waste your time and possibly money on this, it's most likely faulty hardware anyway. You could "adb pull /proc/last_dmsg last_dmsg" then open that file in a text editor and check if the both phones hade the same panel ID. If not, then it could be driver-related. Or maybe it's as simple as a loose connection.

I am pretty sure the flicker is software and not hardware. I get it, it normally starts ( but is not limited to ) when on the home screen. If you are experiencing flicker navigate somewhere with the option to bring up a menu. When I bring up a menu over the flickering screen the menu is solid and does not flicker while the activity underneath is still distorted.
I have tried killing sense to let it restart and that normally gets rid of the flicker.
(I call it flicker but it is really more like the image on the screen warps from the bottom but stays still at the top in a fluctuating way.)

One X Dead

hey guys,
so my friend got a One X, that's Dead...pretty cheap...and we're trying to revive it.
up till now, the phone only vibrates when pressing the power button, screen doesn't wake up. how to access the bootloader "if it's even accessible"?
any way to know if it's fixable?

Uhh, it doesn't sound too easily fixable. If the screen isn't even turning on, you're off to a bad start. Sounds like some kind of hardware fault, not something you'll be able to flash to fix.

That's a hardware fault maybe faulty flex cable

if you look at the phone, it's very clean, i can tell it never had a smudge or any fall...also the screen is clean, no scratches. quite a catch! what could have made the flex cable go bad?!
in the boot animation the screen is quite good!

You say in the boot animation the screen is good, does it ever clear up entirely? You COULD get a display like that from software, but it's more than likely hardware. For example, running Gingerbread ROMs on the Infuse with Froyo bootloaders cause similar rainbow effects due to a change in coding, so you can POSSIBLY have a scrambled display without a hardware failure.
It may have just been a faulty phone and that's why it looks like it's in good shape. It's not necessarily something that someone broke. It could be a bad GPU chip, it could be a flex cable as mentioned, it could be a lot of things. If you (or rather your friend) got it for cheap, and you want to try opening it up to inspect the cables, you can find disassembly threads and videos to tell you how. You could be going on a wild goose chase though.

sometimes it boots up with that white messed up screen, sometimes it boots with the sense 4 lockscreen. lags a lot while trying to unlock the lockscreen, after that all hell breaks loose and screen becomes messed up pretty bad.
thanks for the tips man, i will try opening it up and having a look inside.
it could be a bad factory outlet as a friend suggested...

Well, hell, you can try reflashing the software if you can see enough in recovery mode (vol down and power at the same time). I can't see how it would hurt it any more. From the sound of it, you either have VERY messed up software, or more than likely, faulty hardware. Does it seem like the display works any better when it's been off for a while (cold)? If it gets worse the longer it's on, or if it had been on and you just rebooted, it would point more towards a faulty gpu chip to me and the heat causing the problem to come out.
Not sure about how warranties transfer or if they do at all (might depend country to country too), but you could see if it's still under warranty and can be sent in before you open it up.

alright then
i'll post later if it worked out either ways. thanks for your time bro, unfortunetly i'm out of thanks to thank your last post
actually, the screen gets better when used more to be honest. first we got it, the screen never turned on, then after many tries, it finally came up...first time it was like in the pic, second boot it was sense 4 lockscreen, but messed up later on.

Hmm... weird. Not sure what to say. Well, good luck. I hope it works out!

What honestly it looks like to me is that they tried to flash a american version of a rom on to the phone so you have the improper bootloaders and such. hopefully this works for you.

I know I don't own an one x, but I do have a HTC Rezound, and I cracked the screen in it, and mine did the something while watching YouTube videos, but then it just went back to normal, this happened twice to me. I thought my screen was going out, but if yours is doing it and there's no physical damage, had to be something in the phone, or maybe software is that even possible? Lol.
Just thought I'd share what happened to me..

yes it could be a software issue. so your phone had that issue after changing your digitizer/screen? and then became normally by itself later on...?

[Q] Dead screen

Screen has gone black. Sometimes i can see everything fine for a second and then it just goes black. I know the phone is still on because I can feel the haptic feedback of the buttons even when its black. My question is how do I unroot my phone so I can return it through verizon without the use of the screen? Any help would be appreciated I am at a loss on this.

Like david_hume suggested I would try getting into boot loader first.
My guess is that its hardware failure. If you no longer have warranty/insurance on your phone you could try taking your phone apart. It could be as simple as the connection for the LCD came loose. My other guesses would be the LCD could have went bad or the connection on the PCB failed. You might want to start looking for a donor phone if you can find one cheap. Or if you aren't up for the DIY challenge it could be time for a new phone. If you decide to try fixing it I highly recommend looking for a good tear down video on YouTube.

The phone is still under the htc 1 year warranty so I could have it replaced under that. My only question is will they be able to tell its rooted by hooking it up to a computer or will they just give me a new one since the screen went dead.

I'm not sure about that. I've never done an exchange through them. I have heard of people getting warranty replacements while their phone is rooted but not sure if that is through VZW or HTC.

HTC One X Camera fault

Hi all,
first post here. I've been sucking info from this site for the past year so thank you all for all your helpful info.
I have just bought a HTC one x from a friend with a faulty camera. I was wondering if anyone has come across this fault before. when using the main camera. the screen goes green like it's crashed. all messed up. I don't think it is a hardware fault but then I haven't read this fault anywhere yet.

Yep well known issue.
Its mainly when flash is on right?
This isn't hardware I don't think mate, it is a software bug.

No, what he means is the whole screen is green, can't see anything, which basically means the camera crashed and is either undetectable or damaged, or a kernel problem

Yes thats what i mean. Cant see or do anything. green crashed screen. ive flashed it back to stock and its still the same so im guessing it is damaged camera. painful as camera is on main board to cant really replace it or fix it in any way.

Has anyone else come across this problem? I'm debating weather to just sell it on ebay to recoup some of my money. its definitely not the same issue as the green kind of filter that occurs quite a lot with the camera. I posted it as i couldn't find any posts anywhere about this issue.

it s related to KERNEL.. on ICS is find..so it's a software pb.

Hey this Thread is a bit old, but maybe you're having the same problem I am:
http://forum.xda-developers.com/showthread.php?p=41063671#post41063671
See if it's similar.
If it is, I replaced camera, nothing, flashed rom, nothing, not sure if hardware or software yet, but i changed HBOOT and Flashed ARHD 21.0, and NOTHING happens.. still green :\

Persistent sound issue no matter what

I've done just about everything. There's a log cat below. EVERY ROM, EVERY KERNEL STOCK OR CUSTOM, this issue is there after the first reboot. Im only going to answer every question that goes like "have you tried...." With a full rundown of what I did and results. I will remind I've tried every custom nougat rom, stock or custom and I've tried stock marshmallow rom to. Also some roms haven't even had sound on first boot. Some roms will work for a bit then they will do a soft reboot that takes 30-45 minutes to complete. Then have no sound. I'm open to taking my phone apart since my screen is fu*ked up. Im begging at this point I love this phone, I've had it for 2 months, I don't want to have to buy another one.

Tried unbrick tool yet? That may have a slightly different effect than just flashing stock ROM (as it completely nukes the device and installs everything again).
Anyways, you may have a hardware issue. In that case taking the phone apart won't do much ... You can only check the connections, that's about it.

I did actually brick it awhile back trying to solve that damn sound issue. I used the mega unbrick guide to fix it, I can try again. Cause hell who knows it might fix it. Thanks for the recommendations.

Found out it is hardware i narrowed it to the aux port board which is what the fingerprint sensor, microphone, speaker connect to. I'm ordering a new part tomorrow for it
