Good evening everyone, i am here to request a help about my broken android phone screen to try and figure out how to fix the problem i'm facing, lets go from the start, i have a Samsung galaxy grand 2 (Sm-G7102) which had a really buggy touch, i could barely use the phone due to the cracked screen so one day i got really triggered and tried to take the first layer of the screen off but i ended up taking it all off with the one under it disconnecting the whole display (the thin cable that was connected to the screen got pulled off) now i'm only left with (idk what to call it) the last layer of the screen which is only a clear display but it doesn't respond to my touches anymore, and its locked with a pin lock so there's no way in hell i'm gonna be able to recover my files off of it, i tried everything like screen mirroring and a program which can remove a screen lock but sadly this Grand 2 is hardly supported by anything, and therefor its not gonna work i also tried using some ADB solutions but it wouldn't work, now idk if its me who's an amateur and couldn't use it or if my usb debugging is on, idk even know if my usb debugging is on but i'm sure its not. i don't know what kind of way to try. also my phone have been through a lot, Before the screen stopped working i had a custom recovery and i was curious and did something like ''wipe system'' which took my whole system off (including the custom recovery) cause i wanted to flash my phone to kitkat, so instead when i lost my whole system i downloaded Samsung Mega kitkat firmware and installed it directly to the phone using Odin. and it worked like a charm. Phone is also connected to wifi, connected to 2 of my google accounts, and that's all. Now my questions are:
First: I saw that my grand 2 is not supported by an OTG adapters which was my only hope but it supports the Mega and i have already mentioned that i flashed a Mega kitkat firmware into my Grand 2 does that mean it would work??
2: Second if an adapter doesn't work is there any hope to control my phone with an ADB or any other way?? or at least just to recover my files (It includes very important pictures that i don't want to lose).
Thank you all in advance.

I am totally stock, unrooted.It all started after I turned on Google Now. I was trying it out for a few days, didnt like it so I turned it off. After that, I noticed a considerable dip in battery life. After checking with better battery stats app I found that the phone would no longer go into deep sleep and the culprit was "mhl-kernel-wakelock". I have tried everything to get rid of this wakelock.
I have tried: phone reboot, battery pull, wipe data from all media player apps and usb service, deleted all my apps, reinstalled them. I tried a full data wipe/reset and wiped cache.I tried charging my phone while off. I deleted all my media off of my sd card and got a new sd card. I tried connecting to windows based pc. Nothing works, the wakelock remains.
I have never used my note 2 to connect to the tv or anything like that. Also my usb functionality no longer works. It wont talk to the computer. The phone will charge though. I have searched google extensively and there is very little information regarding this wakelock. I'm afraid it might be at the hardware level. The only other thing I can think of is buying an MHL cable to HDMI and hook it up and hopefully when I disconnect it it will shut off the MHL mode that it is stuck in. Obviously I could also root and flash a ROM with a different kernel, but I really enjoy stock and the spen features etc.
If anyone has any suggestions im wide open. Thanks
EDIT (2/1/13): I also realized that when I tried Google Now was around the same time that my house lost power during the night and the power flickered WHILE my phone was charging from the wall outlet. I initially attributed the problem to Google Now, while in actuality it makes much more sense that a power surge fried my USB port on my phone.
I know this probably isn't the answer you were hoping for but I think it might be a good idea to go ahead and, assuming you're comfortable doing this, root and unlock your device. I recommend you try out Jelly'Beans' Build 4 ROM. It has all the great features of stock with the bonus of being much lighter on your phone (smaller system ROM file) and you can set it up to look like AOSP Jelly Bean. Or if you really don't want that look and prefer TouchWiz, you can do that too.
I would do this anyway as imho, it's better to be unlocked and free for the remainder of days you own this device, rather than get an OTA and lose the possibility of unlocking ever again.
And this has a good chance to resolve your situation as you would be totally wiping the system partition and chances are thats where the issue is.

back up whatever you dont want to lose and wipe data/factory reset from stock recovery. you can try a cache wipe first, but a data wipe will fix guranteed.

Thanks.I already tried this several times. I tried it from the OS and from the recovery. I also lost my usb functionality so im not even sure if I can flash a new rom with odin.
I think I'm screwed. I can't even access the hidden menu from the dialer pad to attempt change the USB mode. It looks like a hardware failure, even though I haven't done anything out of the ordinary. It would explain why its stuck in MHL mode with the constant wakelock (despite multiple factory resets and data wipes). and why no USB ( tried 3 different cables) cable or any number of computers (3 different computers) cannot recognize, connect, or exchange information with it via USB. This blows.
I registered with Samsung and am trying to fill out a service request through their website, but it just says the troubleshooting guide is unavailable right now and it won't let me get past that step to actually request a service repair. FTW
Just an update in case anyone has this problem. I was able to get the battery drain under control. However, I'm not absolutely sure which setting it was, but under screen settings it was either auto-rotate or screen timeout, but I pretty much changed them all back to default, rebooted and changed them back to the way I liked them. For some reason it disengaged the MHL mode that it was stuck on. This is even after 3 factory resets and data wipes.. all it took was to switch one of those on and off.
The other problem I had was that my USB hub quit working, although it would charge, but not communicate with any computer. After a couple more days though, it stopped working altogether. It wouldn't charge my phone or do anything. I tested my charger and cord with another phone and computer it works/charges flawlessly.
After that, I took it into Verizon (crossing my fingers, since I got my Note II on release day with no insurance... so way passed the 14 day return period) and told them that I did get my phone back in late November, but I had never tried to plug it into my computer since I got it (even though I had and new about this problem for awhile) so I told them it was probably defective from the release date, I just didn't know about it. Long story short, after talking with 3 of the reps and them mindlessly googling dead-end solutions that I had already tried, the manager issued DOA on my device and shipped me a new Note II for free.
F yeah... very happy at this point. The new one I got is not a refurb, runs flawlessly. I rooted, unlocked, and running Clean ROM... all right before the OTA hit.
facing same problem with mhl wake lock and my n7100 note 2 is not detected any more when connecting to PC
Hi,
A hour ago i was leaving my work my when i accidentally dropped my phone on the stairs.:crying:
My phone screen doesnt work anymore so i have a real problem now because i flashed my phone several times and of course its rooted.
So i thought of restoring my phone with odin to the stock rom unrooted the only problem i will have is my flash counter i want to send my phone back to samsung but how do i use triangleaway if my phone screen is dead?
Edit: Screen doesnt work, Led does sound does, connecting it to my laptop also works only the screen and the touch buttons (menu & Back) doesnt work (lightup)
Can somebody provide with some advice i really would appreciate it also sorry for my bad english.

Is this related to mhl cable only, or does it happen if you use Chromecast or similar devices? Haven't had a chance to try, so I figured I'd ask.
Sent from my SM-G900T using XDA Free mobile app
Also while watching or listening to music, the lockscreen no longer displays relevant art or album info.
im going to try chromcast tonight ,i have a wdtv box whitch will work with sreen mirroring,
wifi also has a problem
one note i called tmobile and explained my issue now there sending out a free s5, i hope it dont have 5.1.1 on it if,so ill have to downgrade my phone to 4.4 or 5.0
its deffinatly not the cable i tried my wifes s4 on it and it worked with 5.0
its deffinatly the update
whatever you guys do do not let it update
My chromecast works fine.
I reflashed with odin and factory reset. the mhl actually worked for a short while but when i plugged the charger into the mhl adaptor the phone immediately started rebooting even when i disconnected the charger and reconnected the phone it kept rebooting. even if the mhl works unplugging it and replugging into the phone causes it to reboot. Im pretty certain this is a firmware issue so i dont see how exchanging the phone can fix it.
ok I got mhl working with charging. I am using a vga monitor so I am using an mhl adaptor connected to an hdmi to vga convertor. the steps to make it work are not that hard but it is also not as simple as plug and play.
step 1 boot phone and use greenify to hibernate the lockscreen.
step two make sure to have your monitor or tv off and unplugged completely.
step three plug the phone into the adaptor that is connected to the monitor or television that is off and unplugged. step 4 plug in monitor or tv and unlock the screen on your phone. step 5 plug in a 300 mah charger into the mhl adaptor to charge the phone while you are using it. higher capacity chargers in my case cause immediate rebooting. this works on both mine and my wifes phone so it may work for you. good luck.
Edit you dont have to use greenify you can just lock the screen with the power button. Also my wifes phone was not factory reset , just reflashed with odin. Both phones now work well with hml .
well big big big news after i called tmobile they sent me a new phone which only took a day and it came with 5.0 so now i plugged it into my tv now it works i also plugged it into my car now it mirrors on my nav screen
like this i have 3 parts ,im so happy ,i wont make that mistake and update

now i have rooted it and installed the 5.99 titanium backup
and put a freeze on software updates
Mhl does work. When flashing phone make sure you take out your micro SD card and Sim card when flashing. This was my problem I had. Also, odin bootloader and modem first before flashing the actual rom USING ADMINISTRATOR RIGHTS! Found this a problem when trying to install modem. After setting up your phone and reinstalling twrp (optional) everything should be fine UNLESS you are using a multimedia dock or any mhl adapter cable that can trigger dock mode on phones with dock mode. My mhl setup is 5pin mhl to hdmi adapter with 7pin adapter with micro usb input for power. Mhl does work!
no it does not if you have a stock phone and your phone starts updating by itself ,thats what happened to me other wise i would not be trying to warn you guys that this could happens ,its only a heads up all i did was look at my phone for the time and if was finishing updating, i didnt think nothing of it till i pluggged it in my tv and car and it didnt work,im sure what your saying is right but my experiance was differant i didnt even touch the phone
but im all good now they sent me a new phone ,and they no of the complaint
still no more software updates this is great
phone running good still with 5.0
Bluetooth playback and calling still works though. Also OEM bootloader unlocking was removed
Sent from my SM-G900T
5.0 is probably the best out there
Wow, what happen to all the S5 devs here? I mean, there are not many custom roms here, did anyone do a custom 5.1.1 yet? I just see the odin version. ....wondering minds want to know...lol
I have been running the 5.1.1 FOG6 V-X.
This one seems available, and I have booted it no problem, G900T1UVU1BOH1
lol hi hope you are feeling better

So, gave the screen mirroring a try today in the car (Appradio) connected to (Microsoft wireless display adaptor) got video, touch even worked, but the sound came out through the phone. Tried for a while, different apps, nothing, still through phone (Sound)
So tried my old lg g3 worked perfect first time, sound and full mirroring worked.
LEads me to believe its the phone.
Now the s6 is rooted, using unikernel atm.
ive tried using different roms, but they are all linked to samsung ones (Other phones you could have completely custom roms, samsung though apparently not) but the roms where the samsung mirroring is not present, theres no mirroring, tried a google search of an apk to add the lollipop native mirroring, couldnt find it.
So yeah, my last resort, help!! Been at this for five hours now and bricked my phone 3 times, someone please help, i just want to achieve mirroring with sound, i know its samsungs tech i should be going to but lets face it, you guys are armore useful than they are, plus the first person to solve it gets a few beers!!!

You're lucky you're able to mirror even video because when you have a modified kernel, it breaks screen mirroring. Every Samsung i've had I had to stay away from custom kernels because I mirror my screen often enough that i rather stay stock then lose that. Sometimes I could use wanam to fake system status but even then, the mirroring wasnt as smooth as it were on a stock kernel
So if I put the stock kernel back on it then it will work again?? Will I loose root if I do so?
If so is there anyway of keeping root when going back to stock kernel?

Kernel and root and 2 different things. One is dependent on the other but the other is not. You can have stock kernel while rooted without a problem. Thats what I do.
You can flash stock kernel in recovery and you will stay rooted.
Well I managed to get screen mirroring to work. Stumbled across a rom called echorom. That appears to work whilst keeping both gear manager and root. So happy days. Figured I'd post the solution as not many do.

So this is an old problem, and I'm kind've just hoping someone knows what's wrong with the phone even though it doesn't really matter anymore, because I'm genuinely curious. So a few years ago, I was running an unofficial CM12 build on my Sprint Galaxy S4, and I'd been using the ROM for about two months, give or take a few weeks. One day I just took a picture, and it turned off. But I couldn't turn it back on. And I still can't.
I've tried charging it, it's charged but it wont boot the main ROM, it wont recovery, it wont boot download mode/bootloader, it wont boot into safe mode. My laptop doesnt register it when i connect it through USB either (of course) so can't do anything with the laptop. It just shows "Samsung, galaxy S4" and just turns back off. If I want to make another attempt at powering it on in any way, I have to take out the battery and try again.
If anyone has any idea how to fix it, or AT LEAST what's wrong with it (again, I have a fully functional Note 5, I don't NEED the S4 to work) I would really appreciate the help. Thanks in advance.
