Hi all. A friend gives me a Redmi Note 3 (MTK) for replacing the lcd and touch. But, after replacing those parts, the Redmi won't turn on, and goes Bootloop on MI logo. I tried to go in recovery mode, but not work. I downloaded the leatest hennessy stable image (fastboot version) from xiaomi and then I correctly flashed him with SP Flash Tool, but the bootloop seems remaning. I also tried to flash the xiaomi.eu V 7.5.1.0 (Quaze) and the V 7.2.3.0 (JamFlux) without preloader check, but the result is the same: bootloop.
What I can do? I didn't touch anything about software before this problem! I simply follow a guide for replacing the LCD screen (isn't my first time for replacing LCD in smartphones), I unmount anything and then re-mount, but the problem still the bootloop. I don't understand what to do. The phone has locked bootloader (the user didn't made anything with it), but goes in fastboot mode. There's any command to know what is wrong whit this redmi? I'm really furios, this is my first broken smartphone for repairing, but it isn't mine... And i'm in trouble... HELP ME!

sorry but I think only way to see if the problem is in the display is getting another MTK device and try to test this one motherboard in other device with original display.
UPDATE: Tried to change the flex motherboard to usb port cable (seems damaged) but stills on bootloop. I have acces to fastboot, there's someone with a big heart that tells me any hoping question or solution?
Sorry can't really help but AFAIK there is a amount of different components used in our Xiaomi phones. Different lcds, different fingerprint etc etc.... Maybe your new Display is from a different manufacturer and that's why u got a bootloop.. maybe flashing a new rom could help because it uses other software ?!
Same problem. I just disassembled and assembled the phone (I was looking for a way to replace a broken touch). Seems like failed boot checks for device response (glass was broken a month ago but the phone was rebooted recently)

Hi !
Today the screen of my Cubot One went black, when I turn it on and off the problem remains, I can still lock the screen.
I downloaded a ROM and I tried installing it with both "Smart Phone Flash Tool" and "SP Flash tool" (Or maybe it is 2 different versions of the same software).
I load the scatter file but when I hit the "download' button nothing happens...
Can you please help me with my problem ?
Edit: Now I get this message: "ENABLE DRAM FAILED!"
rscredin The

My phone is experimenting some similar issue
I tried to change the recovery in my cubot one (the grey one), supossedly it has the mt6589t SoC, but every try failed, then I thought to change the firmware (the firmware the phone had was G800_CUBOT_D1_V1.3_"some_number_here"_MJK), with the firmware G800_CUBOT_D1_V0.8_20140124_MJK, i employed the SP tools without problem, the download was succefully, the i put the battery on again, then i switched it on, the telephone started, the screen lites on, but the screen keeps black, it sounds like boots normally, even the unlock screen sound normal, but there is no image in the screen, I've looked for the newer firmware everywhere but I did not found it, somebody could help me, please!!!
The firmware I used to flash the phone succesfully was the cubot one turbo available in the needrom page. Maybe the newer versions of cubot one have a new graphic chip or something different.
The error...

hi i have same problem, i install the rom that download of needrom but not work fine, i install the rom succesfull but my screen is black, phone turns on, I can unlock and lock it, volume buttons work, but there is simply no image.
are you have any solution?
Guys I need a help, my S3 touchscreen is not responding, the screen is normal but when I touch there is nothing happen, I think the problem is when i want to install CWM using odin, when the flash completed the screen got unknown error. Then I flash using stock ROM and no luck, also booting time is take a longtime not as ussual. what should I do?
Usually happens after flashing a firmware/recovery for the wrong model of S3, if screen is still not working in recovery then you'll need a new screen assembly as the digitizer in the old one is blown.
bought a phone advertised as ulefone u692.
tried to flash cwm to devive , lost recovery.
tried to flash stock firmware to device in hope of fixing afore mentioned problem.
epic fail phone boots but screen is black.
after many attempts and downloading numerous roms and flashing numerous file....finally get it to boot but with several driver issues! many sensors not detected.
what i have found out is the screen is 1920x1080 as opposed to the ulefone u692 which has 1280x720, hence the black screen issue.
everything else says it is right apart from screen resolution.
i do hear cpu info can be faked, how do i check my real cpu info?
would it be possible to add the screen driver to the stock u692 kernel?
thanks.
Hi bro
Please remember , always backup all partitions first on unknown mtk phones.
i wonder your IMEI isn't lost too,
try this tool -> http://forum.xda-developers.com/showthread.php?t=2160490
Don't buy copycats....
So... I recently got a chuwi hi 9 plus and yesterday I decided to root it (installing twrp) but eventually it got stuck in bootloop mode, i managed to bring him to life again flashing his rom with sp flash tool and this is the result:
ibb.co/0cpFsHR
ibb.co/23nYv3F
as you can see from the images the display is moved to the center (i don't know how to explain this problem) but the touchscreen still works well. Any ideas how to fix this?

Hi there,
Unfortunately I cannot help you with that problem as I'm not experimented enough with umidigi phone (that are more and more common around here). But I though a little response would be enough to warm your sad heart.
Also could you clarify what's going on with your IMEI?
Also, you double posted this question, let me ask @xanthrax for help with that
Here is the double one:

Hello,
Thanks for your reply
As for IMEI, I fixed it, it remained a problem. The phone no longer accepts lock mode and when I lock the screen and open it again the phone stops working with a black screen until I restart it and some applications do not work
Any help @xanthrax !? please
