Hello i wanted to root and unlock my SM-T220 and did all of that and then tried to remove the warning by overwriting up_param from termux
That resulted in bootlooping with only backlight on
Then i tried recovering using MTK SP Flash but now it only shows up as MTK usb device cant even get to bootloader, is the tablet toast?
Can you boot it to EDL?
You shouldn't have done it with Termux anyways since it was fully booted from the beginning.

I unlocked the bootloader, i've opened the device up so i think i did
Does the screen come on at all when you power it up?
If it does, put it in download mode:
Power device off completely with no cables connected
Hold both Volume buttons, do not press Power, connect USB cable from PC
Device should start in download mode
Reflash firmware using Odin

Hi XDA members
How are you
My friend brought me his phone
The screen is black, seems problem with the LCD itself, i dont know if its a connection problem or what
The phone is working, you can boot it and hear the sound of booting
The problem is when i plug it in the PC, and open it. The files does not appear because the phone has lockscreen " password " and i cant enter it because of the dead screen
The phone is not roooted
debug mode not enabled
is there a way to remove that lock screen or remove somefiles from it ? any ideas
I tried ti install the drivers for it, no luck, the device never show in adb device list
Thanks if anyhas some ideas ?

Flash CWM recovery, boot into recovery and adb pull the files. Use adb shell + cd and ls to find where everything is. If it doesn't work then you might need to recovery root the phone as well by looking at a picture of cwm to see what to click or by flashing cf-auto-root (then reflashing cwm since cf gives you stock recovery).

Try reinstalling the drivers. You could also try making a nandroid on your ext SD and unpacking the parts to extract your data.

what i did. I brought an S3 that works fine, I removed both back cover of the broken S3 and the working one
then you remove the screws, and remove the upper black cover in both
there is a wire which is attached in the right side i thinkm its a bit big, you can see it coming from below ( the screen )
I deatached the one in my broken phone, then i attached in it the one from the working S3
then i opened the device, copied everythiing, and return the cords as normal
I see thanks
I am trying to unlock my bootbloader but I can't seem to get my phone to boot into fastboot. I have tried the official method posted through the Sony Developer site and It says to Hold the power button + Volume down at the same time and plug it into your computer. And when I do this, a blue light should come on notifying me that I'm in fastboot mode. But no matter how much I try this, my phone simply just changes its state to charging. Can someone please help me out?

Have you checked that your bootloader is unlockable in service menu ?
Dears, I was (was) getting excited about the Oreo upgrade for our Z3 Tablet and I started the needs by following the related thread but when I flashed the boot.img........ after that, Windows started to recognize it as "Unkno w USB Device (Configuration Description Request Failed).
Now it doesn't boot anymore and it is not recognized by the system. I tried also from another PC with Windows 10 but same result....
How can I fix it?

My guess is that your device either got hard-bricked or that you need to re-install the drivers on your PC (e.g. with Flashtool).

thanks, I tested it also under macOS... it's hard brick. There is any way to bring it at life?
Thanks for your support
Can you boot in fastboot mode? Or is your device not recognized in fastboot mode? If you can you can try flashing stock firmware with Flashtool. If not, I can't help you any further :crying:

I had this exact issue, adb worked properly when phone was on, and in fastbootd as well but in regular fastboot the phone wasn't detected at all, turned out the issue was the usb-c cable I was using, so be sure to try another one if you have it already, but before you go out and buy an extra usb-c cable check if there's any warnings about the driver in your device manager, I hear that's also a possible cause.

Can I do it without administrator privileges? The only other computer I have is my school computer, and well, it doesn't have administrator rights.
Hi, I literally f**ked up my root progress with patched boot.img.
I'm using a phone that is a clone of Panasonic Eluga x1 Pro. I decided to root it with magisk patched root.img. Simply flashed the patched img with adb using "fastboot flash boot patched_boot.img" and ran "fastboot restart" to restart it to my system, it didn't booted up since. I can't go in recovery mode, the phone is literally not giving or receiving anything.

In the Device Manager on PC, it simply says "MediaTek Preloader USB VCOM (Android) (COM12)" about my phone i think.
I don't wanna be that guy but your phone is, think of a person who's alive but can't speak, move, nod, anything, for itself.
However, you may have luck, because they're still repairable, but your best bet is take it back and play dumb, they don't have the time/willingness/resources to check whether you messed with it. Went to bed, woke up, i swear, i dunno, it was like that, tsk, tsk, tsk...

enter fastboot devices , if the computer recognizes your device, flash the stock rom, otherwise try to find a way to get into edl mode on youtube until the computer recognizes your device. EDL is just a 2nd bootloader (maybe?)
