[HELP] Stuck in Fastboot loop! Unable/Unsure how to put data on the sdcard - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

Hi,
I'll start by saying this is the first time i've tried putting a custom rom on a phone.
I unlocked the device, enabled usb debugging and installed twrp. I was able to get into recovery mode and wiped the correct partitions.
I was then unable to install pixel experience? I was unsure how to put the rom on the phone. It was not coming up on my pc when connected.
I then disabled MTP and rebooted the phone. It went straight to fastboot and no matter how many times i reflash twrp, or what button combinations i push, i'm stuck in fastboot.
Can anyone help?!
Thanks in advance!
A helpless noob

[Q] Bricked L70

Hi,
so I rooted my phone, unlocked the bootloader, installed TWRP, put in 3 different ROMs on my External SD card, went ahead, deleted EVERYTHING from the phone, tried flashing ROMs, not a single one worked.
I rebooted the phone because I saw no other option, TWRP said that there is no OS, I went ahead and did it.
Now the phone won't start, I tried returning it to stock firmware as per lg-phones website guide (worked before, though my phone was not this messed up, I could access download mode and now I can't), but I keep getting connection problems. I have tried doing this with the phone just "turned on", it hangs on LG logo for infinity.
When I try putting the phone in download mode, the only thing I get is fastboot. When I try to use adb devices and other similar commands, it says device not found or simply does not list it, regardless of the "mode" the phone is in. However if I try and use LAF RECOVERY MULTITOOL, it detects my phone and I can use fastboot commands. I have custom recovery, boot and laf imgs on my PC, I tried flashing them all, PC and phone tell me everything's ok, but when I restart the phone, I get nothing... what am I doing wrong, and can this be fixed? If you have any questions, I'll answer to the best of my ability.
Thanks in advance!
SOLVED!!!!
Just found a backup laf.img that enables download mode... PHEW!

xperia Z3c bootloop after flashing CWM

I recently got a z3c and decided to try to get a slim rom on it.
I have done the following:
I unlocked the bootloader.
This was done successfully to the best of my knowledge
The next thing I did was flash a cwm image to by z3c using fastboot. The problem was that I flashed the z3 version on my z3c.
The device would boot but the screen would be blank.
Later I flashed the z3c boot loader named : Z3c_DooMLoRD_AdvStkKernel_v01_FW-105
After this the device goes in a boot loop. I am able to access CWM.
I have tried to root the phone as well as flash the slim rom in an attempt to fix it....
Wiping disk / cache doesn't help.
Also for some reason even though adb drivers are installed I cannot use it so I can't get the twrp install to work.
I have no idea what to do can someone please help?
Thanks,
stp
I have same issue....Phone is ib bootloop...i can still go to fastboot mode....
Anything can be done here????
Flash an factory image with flashtool then you will have original recovery. Then reinstall CWM, maybe smth went wrong.
Tried flashtool---Ended up with errors as attached pic
As i cant bootup my phone...USB Debugging option cant be ticked
I was running SlimLP (unofficial) while bricked my phone....
Anything on that please....
I managed to recover my phone. I don't think you need usb debugging for flash tool. What I did was turn the phone off (power and volume up seem to be the buttons that force shutdown and break the reboot loop).
flashtool will prompt you to connect when you flash the ftf file and you hold power up and volume down when you connect the usb cable. If you have issues flashing (it hanged on me on system.bin) try restarting your computer.
Resolution and Problem Exp
Right after flashing the device recovery through fastboot the USB cable is plugged and that seems to loop the boot loader, so you need to force shutdown while looping by pressing POWER + VOLUME UP, and after that unplug the USB cable. You will notice that on boot now the light is no longer red.

Cannot connect to fastboot through ADB

Hi guys. I've had my HTC one for a while now and it had TWRP flashed on it. About a week ago I flashed the android revolution rom, worked well but my camera went really weird if I looked back at some recordings. So I wanted to revert back to stock everything. I flashed a stock recovery for the M7, after that I had the problem of not being able to connect my device to the computer when I fastboot mode. Simply wouldn't pick it up when I typed ADB devices in cmd. My device wouldn't show up after installing stock recovery. And it doesn't want to restore any roms either in stock recovery mode. I can't even access my folders in that mode to flash any roms. I click either apply from sd card, apply from phone storage. Says for a split second check CID failed or something and reboots itself.
I cannot flash TWRP back cause my computer since it can't pick it up. I've tried everything. Changing USB ports, uninstalling my drives for htc. Changing computers, unlocking, relocking bootloader. No result. I'm screwed cause I'm stuck on this android revolution rom, rooted. Just wanna flash custom recovery. I can connect it to my computer, access folders and add things to it but soon as I turn it off and go into fastboot mode it says fastboot usb and can hear the noise when its connected but it doesn't show up in adb devices and when I flash the TWRP it starts send then comes up with FAILED. Help please, would be appreciated!

Adb only works if you'te booted to OS or custom recovery. Command you're looking for in bootloader menu is "fastboot devices"
Fala Puno. Ja sam raditi sada. I'm of Croatian decent in Australia. I'll try this later when I return home
Fixed it! I'm an idiot, I didn't realise I was flashing the m8 twrp instead of m7. That's why it failed. Lol. Anyway thanks

Oneplus 3T will not boot into full recovery

I updated my oneplus and i got the TWRP decryption message, so i formatted it back to the stock format.
now all the phone does is boot into the bootloader but gets stuck on the boot screen of Blu Spark 3.1.1
my computer wont recognize it while its in the bootloader or while its stuck trying to boot in twrp
is there anything i can do or is my phone screwed at this point? i see a lot of threads that would answer parts of my issue but nothing that covers this as a whole. id rather ask for help now while there may be some hope.

So no response to fastboot commands, while in bootloader-fastboot mode?
Are you sure you installed the right drivers for your pc? If all else fails, you can do this.
This is how I fixed my phone when i was stuck at a black screen. You can also try a different usb cord or port. Check device manager and see if it recognizes it when its plugged in. hope this helps!

can you boot into fastboot? if your phone can boot to fastboot mode..just flash stock recovery image..then flash rom via adb shell (better flash the stock rom). if it works you can reinstall the custom recovery image or something. dont forget to erase everything via stock recovery..

How do I unbrick my unrooted HTC 626G?

(I couldn't find this exact problem on the forums, forgive me if I overlooked it)
I tried booting my mom's old phone, an HTC Desire 626G, but it is stuck in a bootloop. When I try to enter recovery mode (by pressing power + volume down), it just enters the loop again.
I can however enter what I think is the bootloader menu, giving me three options: recovery, fastboot or normal boot. Fastboot freezes the phone, the other two options just start the bootloop. I've never installed a custom ROM.
I disassembled the phone, un- and replugged the battery to no avail. I tried ADB but I never enabled USB debugging in the first place, so that doesn't work either.
Do you have another idea that might work?

Bro You need to flash the factory firmware using a pc with that fastboot mode.....
The existing firmware might have been got corrupted or the storage might have been damaged, since its an old device(which is very rare),
To do so u can find many articles on the internet very easily,

Thanks a lot, I'm finally able to communicate with my phone via PC now. Booting still doesn't work but now I can at least format the storage and hopefully flash the factory ROM.
