Help with persistent bootloop - Xiaomi Redmi Note 4 Questions & Answers

So I was bored and bought a bricked Nikel Redmi Note 4 from ebay. According to the seller it hanged on the camera app and upon reboot it was stuck on the bootloop. He tried reflashing the rom to no avail and so did I. Any Ideas?
I tried using SPFlash to readback some emmc areas, mainly those that should not have been touched by the flasher (the ones marked as protected or invisible in the scatter) and most of them seem to be blank. If anyone could dump their own partitions and check with a hex editor if there should be values stored in there I'd appreciate it as this is my only lead other than a malfunctioning motherboard.
Thanks.

Help on bricked Clone N9000 note 3 phone

Hello!
I have a Galaxy Note 3 phone that no longer boots after I tried a hard reset. I maybe stupidly cleared that cache and it froze during the process making me remove that battery. Now it just flashes and goes dead when connected to power or when i try switching on.
The challenge is that I don't know the chip type though its MTK. I also am not sure if its Korean or Chinese clone going by the "fake" label.
I also see this "a3_mb_v1.0." on it and dont know if it has to do with the chip. I have tried flashing with the following roms mt6582 and mt6572 both keep getting the message that the scatter file does not match the chip.
Can anyone help me with link to a rom that works?:crying:

HELP softbricked my Chinese clone tablet

I acidently bricked my Chinese clone tablet. I got it from Aliexpress (here is the URL http://www.aliexpress.com/snapshot/7000961874.html?orderId=70071566001044) I can get into TWRP OK. but when I boot into the OS I just get short lines across the center of the screen. If this was a PC I would guess it is a problem with the video card driver. Not sure if the same guesses apply here. I did a backup but it ended up corrupted and unusable. Would anyone have some suggestions of ROM's I could try to bring this back to life? When it was working, was looking around in the files, in one of the boot areas found a ton if SAMSUNG logo stuff, not sure if this make it a Samsung clone.
It was/is called a model N9106 or N9101 (forgot which) and the number HK-MTK6582 were in there if that helps.
Thanks in advance for any hints.

Bootloop after lcd replacement

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)

after new android install - red logo teekey appear

Hi Guys, could you please help me?
I download and install new android on my ulefone power 3s yesterday, everything passed ok, without errors, but now red logo on right corner appears which is visible almoust everywhere (probably developer sign) how can I remove it? do you have any ideas?
I`ll be very thankfull for every advice
Sadly this is a consequence of not backing up certain partitions prior to flashing the phone. I have got the same issue on an Oukitel K10. Best explanation I have found so far is here: https://forum.xda-developers.com/android/help/allcall-s1-x-official-firmware-v1-t3870503
Mine came about after following the official upgrade process from the manufacturer!
Assume that your device is rooted with rw access to both vendor n system dir....
Try look into this line entry in build.prop in /vendor dir.
ro.mtk_trustkernel_tee_support=1
change the value to 0 fixed the watermark appearance on my oukitel u223 oreo stock rom.
