Question Lenovo Legion Duel 2 Stuck on Fastboot screen after QFIL (Bootloop) - Lenovo Legion Phone Duel 2

Can anyone help? For the life of me I can't get it to go into recovery mode or anything of the like after attempting a flash of official firmware.

---

It's not being picked up by ADB, fastboot OR Lenovo's smart recovery crap.

my Duel 2 is now stucked on FastBoot and cant select other options like START or Recovery Mode..
Now im trying to use QFil but im having an error:
"Download fail: Sahara Fail: QSaharaServer Fail: Process Fail"
Btw these are the files in the ROM 12.5.188ST thats appearing when selecting PROGRAMMER:
and on the XML:
Patch:
Tried:
prog_firehose_ddr.elf
rawprogram_unparsed0 (also tried selecting all files)
patch0 (also tried selecting all files)
Sorry this is my 1st time doing this stuff and i have no idea..
Hope someone can help me fix my Duel 2. Thank you

Duel 2 ของฉันติดอยู่ที่ FastBoot และไม่สามารถเลือกตัวเลือกอื่น ๆ เช่น START หรือ Recovery Mode..
ตอนนี้ฉันกำลังพยายามใช้ QFil แต่มีข้อผิดพลาด:
"การดาวน์โหลดล้มเหลว: Sahara ล้มเหลว: QSaharaServer ล้มเหลว: กระบวนการล้มเหลว"

นี่เป็นไฟล์ใน ROM 12.5.188ST ที่ปรากฏขึ้นเมื่อเลือกโปรแกรมเมอร์:

และใน XML:

พยายาม:
prog_firehose_ddr.elf
rawprogram_unparsed0 (ลองเลือกไฟล์ทั้งหมดด้วย)
patch0 (ลองเลือกไฟล์ทั้งหมดด้วย)
ขออภัย นี่เป็นครั้งแรกที่ฉันทำสิ่งนี้และฉันไม่รู้ ..
หวังว่าใครบางคนสามารถช่วยฉันแก้ไข Duel 2 ของฉันได้ ขอบคุณ

try going into your firehose options and select erase all before flashing. other than that im uploading all the partitions ive made copies of using qfil. You can try flashing them over one by one in qfil or see if fastboot flash will work . https://mega.nz/folder/TqxSjYrD#l3GM8SQgJcxhVrSeXMLW7Q

great work, its really appreciated. will these work on cn and global roms? or are they rom specific? and would it be possible to write a fastboot flashable script to make flashing the partitions easier? (for noobs like me who don't know how to flash them all manually) thanks again

completely forgot to specify which rom it was lol. its global
if you use fastboot flash commands you just go off of the file name . fastboot flash boot boot_a.bin fastboot flash vbmeta vbmeta_a.bin . im pretty sure you can reuse the same file for both partitions. fastboot flash boot_a boot.bin | fastboot flash boot_b boot_a.bin etc. to make a windows script you'd write out each command in notepad then save it as a bat file.
You can also install them all manually using qfil.
-1. put phone into edl mode
-2. select firehose_ddr under the flatbuild section
-3. click on tools / partition manager
-4. right click a partition
-5. manage partition data
-6. load image (if you want you can erase the partition before loading the image )
-7. pick matching file, it immediately flashes it to your phone
-8. rinse and repeat
how i got out of the bootlop was using the file from rescue smart assistant. id flash it in qfil using the meta build option, and ddr firehose. then boot up into the bootloader and flash a persist image I had previously saved. if it doesnt work for you I can upload that image and see if that helps

I had the same issue of it not flashing and it fixed the problem . When your stuck with a $500+ paperweight and nothing else works ya get kind of desperate after awhile lol. Figured it'd have a better chance of working with a clean slate then trying to write over something that's broken

Make sure the device is off, hold the volume down button and turn it on, will boot into the loader menu, plug in to usb side port and type fastboot reboot fastboot, it will reboot into fastbootd and now can flash through fastboot.

i tried both qfil and fast boot same issue

Windows or Linux? If windows, look in Device manager when you do fastboot reboot fastboot and see if there is an exclamation in the list of devices, if so you will need to update the driver manually to android adb device (which is also the driver for fastboot). Which model do you own, Duel 2 or Pro 2? Have you tried Lenovo's RSA software tool since adb works? Use RSA only if it is a Duel 2, if it's a Pro 2 you will have to gather the right bundle posted on another thread (do not use it if you don't know as it can cause further issues).
