Hello, i recently ordered a new digitizer & lcd for my phone but the phone stucks on samsung core 2 logo when i turn it on.
I figured out that the problem is the digitizer and not the lcd since the new lcd boots with the old digitizer.
BUT if i turn on the phone with the old parts and replace the lcd+digitizer while the phone is turned on, everything works perfect until you turn off the phone again and it stucks at logo again.
So, i assume that there is a code in the firmware that doesnt let the phone boot with thirdparty replacements. If i am correct, will a custom firmware solve my problem? Or, is there any other solution?

Hi there,
I have a weird Samsung phone - galaxy trend (GT-S7560) which is stuck in a boot loop. It started after I have replaced the screen due to a cracked screen. I was trying to boot it in a recovery mode, which seems to be both volume buttons + menu + power but it doesn't boot to recovery mode. I could only get it to boot in downloading mode (volume down + menu + power) but dont know what to do from there.
I have tried Kies, its stuck on connecting screen.
ADB doesn't seem to work either.
I'm clueless and frustrated. Please help
Many thanks!

One thing I forgot to mention is that when I was replacing digitizer on that phone the flex was sort of in the wrong place. Honestly it was almost 1 cm to the right as compared to the original and it didnt fit smoothly into the connector because the cable path was angled instead of straight. Could that be the boot loot problem? I have ordered a new digitizer already. Just need to wait 2 weeks :s
I think it's lcd with touch screen connection problem or not working touch screen/lcd . I has about 5 phones in this month (7560 & 7562) with broken lcd or touch screen and some of them after replacement was working, some not. And I changed again touch screen/lcd to new one, then I got them working. After that I've checked one of working phone, just disconnected touch screen from lcd a got boot loop. When I connected touch screen back to lcd, phone booted normally. So you have to wait for a new digitizer and then I hope your problem will be solved.

Trust me...
The digitizer is the problem.
I am encountering this problem 5th time (all of them, I changed digitizers... until the cable fit correctly, It will stay on samsung logo)
The digitizer is the problem. for sure !!
This problem was driving me crazy until I found this post! My Trend was working flawlessly before replacing a cracked digitizer and after replacement I faced a boot-loop, reinstalled stock firmware with Odin but nothing helped.
Now I'm waiting for a new replacement digitizer, I have to say that the non-working one was NOT original.

i found the solution my friend,you have to let the phone boot with the old digitizer,then when the boot its complete,remove the lcd and digitizer,replace with the new digitizer but be carefull the phone has to stay on .and conect back the lcd and its works but if you reboot the phone will stuck again.this is my short fix.
i hope i helped

This is not a Solution bro... its just a confirmation that, the digitizer is the problem... doing your such suggested fix i think is a total waste of time and effort you may even end up breaking the phone because of hot plugin

Same exact problem, I unplugged the digitizer from the LCD BUT leave the LCD plugged in and all goes well but obv the touch doesn't cuz I unplugged it. Some about the digitzer I'm thinking. Because if you plug in the old setup and let it fully boot up; then unplug the old and plug in the new everything works but if you reboot it will get hung at the Samsung logo again. Very very Weird
having the same problem with 2 mega i527's anyone out there found a solution?? replaced with multiple "full assemblies" and still boot loop. OEM works perfect but is cracked.
Hello, I have problem with lcd on samsung galaxy s3... When I turn my lcd on, it just flashes. Touch screen and everything else is doing normal, but lcd act like it loses power immediately when is turn on. I haven't dropped it or anything before that happened. I already tried to remove battery and pressing the power button and tried if the connector is loosen, but everything seems normal.

Boot into download mode, if still the same then it's hardware.
First replace the battery, if still the same then dismantle the phone, check screen connector. After that it's time for a new screen/phone.
I can't get into the download mode, screen is blank after flash... Battery and connector are fine.
Hello guys. I am doing this thread to find some help or at least some explanation for my problem.
I will start from 0, I got a N910T model last 2 weeks since my old N910H model screen got broken.
The issue appeared randomly. First is that when I put my phone to sleep (standby) by a minute or two and when I tried to unlock it it freezes, It totally freezes without posibility to unlock and after a moment the phone turns off, or at least tries to reboot but screen always stays black, I just remove the battery and it turn on again, but after setting my password and locking the phone again it freezes again and do the same thing, I was having my phone rooted but with stock ROM using BeastMode kernel and before today my device was working awesome. After having that I just tried to go to the TWRP and delete cache, thinking that was the problem, but when I select reboot to system the screen stayed black, no Tmobile sound, no led, nothing. And then I decided to flash it through odin, but everytime the device starting installing updates it finish it but then the screen got black with no life signal. without success I decide to install a custom recovery to let the boot start and then it works, but now everytime I lock the phone again it got the same problem PLUS after a minute staying like that it boot me to download mode... while I was reading it it shows a like saying: mmc_read_fail... now i have it with wakelock powermanager app and its working fine when I lock it, but when i disable it, it throws the same problem, plus I cant reboot the phone while is on, everytime I press the reboot key it just freezes and turns black... I need help.
There's no permanent software fix for the emmc issue, it's a hardware failure. It's best if you just look for a replacement device.
EMMC Failure is fatal....
Like seriosbrad said before, the EMMC failure/error is an hardware issue. Only way to solve this problems is to replace the mainboard. I also had an EMMC error once. I had to replace my mainboard. But it's not as difficult as it sounds.. You will need only one very small screwdriver, a thin plate (to stick in the gap between screen and frame) and a new Mainboard of course
But there is no other solution, sorry....

Hi, can anyone help me out?
I have a Samsung galaxy tab s3 -(Sm-T820 ud) rev. pie9.
I changed the battery because it would not turn on, when it tried to do so, it would just shut off,(never passed the galaxy tab page).
now with the new battery fully charged although it never shows the battery level, the tablet wont turn on and is stuck with the message recovery booting..... and with black screen, it just turns off and then on over and over.
I tried to connect to my pc but the tab is not detectable threw USB cable.
attached is a photo of the screen.
Please if anyone can give me some suggestions on how to get it up and ready again.
Do I have to reinstall everything or what????? and how to do it and what to use.
