[General Questions and Answers] Oleg69:
Hello everyone, I need some help.

On november 2021 I purchased Nokia 1.4 and that day when alarm was ringing my phone screen frozen/stopped. Screen sensor and the buttons stopped was not responding. I googled immediately and found the way to turn off forzen Nokia 1.4 by pressing Wolume up + Power off buttons same time (Source: https://www.nokia.com/phones/en_int...-reboot-my-smartphone-when-its-not-responding ).

When my phone turned on again I was happy till the next restarting of my phone. My nokia get Stucked in a Reboot Loop.

Screen lights and when Android GO Logo appears it turns off again and again.

I tried to flash my phone using QFIL Tool but there was unsolved issue of Android ADB Interface driver. The QFIL Tool couldn't detected my device. Mybe it needed different keys combination when connectiong it to PC to boot.

QFIL Tool source: https://androidmtk.com/download-qualcomm-flash-image-loader-qfil

Than I unlocked bootloader using this command:

fastboot oem unlock-go

I thought it was boot or recovery fail and by the reason I downloaded the firmware from alien9firmware

Source: https://alien9firmware.com/index.php?a=downloads&b=file&id=1325

Because QFIL Tool did not work I flashed boot and recovery via ADB. I moved these two .img files to disk C and ran the following commands

fastboot devices
fastboot reboot bootloader
fastboot flash recovery c:\recovery.img
fastboot flash boot c:\boot.img
fastboot reboot bootloader
fastboot erase cache
fastboot reboot

Disconnect device

You guess what do you think guys happen 🤣

My nokia was still stucked in reboot Loop.

Than I googled smartphones with same Core Qualcome QM 215 and downloaded Nokia 8 and Nokia 6.2 TWRPs from twrp official website.

ADB thrown me an error when I tried to flash Nokia 8 TWRP. "The file is too large and blablabla..."

Then I tried to flashed twrp-3.6.0_9-0-SLD_sprout(nokia6.2) with no errors.

I have never seen anything like that. When I press to "Power button + Volume down" buttons my phone shows the stock recovery again which has no matter.

Then I gooled so many times I and I made a decision that every smartphone with Qualcomm QM215 core has absolutely same bugs.

There are smartphones with this terrible Processor:

Smartphones with Qualcomm Snapdragon 215 processor

List of smartphones that works with Qualcomm Snapdragon 215 processor inside.

Than I found this video. In this video he used dryer and it worked. Unfortunately I have not dryer and... It may works on our devices too, Who knows...

Than someone told me to use MiFlash tool to boot my device. I faced another problem the firmware backup was missing the boot_lock.bat file. I had to download Xiaomi Kenzo global firmware to copy and modify the .bat files to my firmware backup. That trying became my night mare. I accidently erased Bootloader.

Today I was searching how connect How to a connect phone with erased bootloader to pc and I found this:

Than I connected my phone to pc via usb and opened Device manager. There appeared QHSUSB_BULK device missing driver.

Then I found the driver here: https://fixfirmware.com/qhsusb-bulk-driver/

At least I managed to connect my device to pc again. And now QFIL Tool detects my phone.

Problems never ends. I downloaded 5 firmwares from different websites and the emmc filefouse prog_emmc_firehose *** ddr.mbn and Rawprogram .xml files missing in all of them.

Do someone know where can I fount the emmc Firehose and Rawprogram .xml files?
