WF Swift is hardbricked. Help me unbrick please!!!

Hey guys
Please may your help me. I recently bought a Wileyfox Swift and decided to install CyanogenMod 12.1 for my phone. I installed CM12.1 successfully and used it for a week. 2 days ago I tried to restore stock by fastbooting the ROM found on NeedROM. After it installed my Swift just turned off and couldn't turn back on. My PC sees it as Relink HS-USB QDLoader 9008. May someone please provide me with a way to unbrick this device?
Thanks
Regards

Connect phone to computer.
Take off battery. And wait.

Is your pc can detect your device on bootloader mode?

Or google "Unbrick All Qualcomm Snapdragon’s from Qualcomm HS-USB QDLoader 9008 (if you have the right kind of rom)"
And use that method.

Yes

Hi @FindYanot , are you able to upload WileyfoxTool1.0 exe on your website and also MEGA? I can't register at 4pda.ru as I always fail the CAPTCHA, even when I use the Russian Keyboard Viewer on Mac.
I have obtained the Android One (General Mobile 4G LUZ17E Retail build) prog_emmc_firehose_8916.mbn , emmc_appsboot.mbn , patch0.xml , rawprogram_upgrade.xml , system.img , NON-HLOS.bin etc. files from Longcheer but I can't get into Emergency Download Mode from my hardbricked Swift, even when pressing Volume Up or Volume Down + Power when inserting USB cable. 'fastboot devices' doesn't list the phone when connected via USB cable, and QFIL 2.0.0.3 within QPST 2.7.429 Qualcomm 9008 2.1.0.5 on Windows 10 x86 gives me a Sahara error and RELINK / Woowellstrong Electronic co., ltd 9008 2.0.0.0 on Windows 8.1 x64 gives me an EDL error.
Thank you.

use SP Flash Tool to reflash your stock rom
download it and download your official stock rom and connect it to pc
after flashing unplug your mobile from pc and power it on and replug and power on it will work

Back to stocn

Hello everyone,
I recently stopped using my Nokia 8 in favor of my new iPhone 11. However, I wanted to keep it just so I have an emergency Android phone. I found an article that says that there is a possible way to update Nokia 8 via TWRP. Of course, I didn’t trust it, so I backed up my phone via TWRP. Here are the steps I took after back up:
- I deleted everything from the device including the OS, excluding SD
- I tried installing the image but it failed
- I then restored my backup
However, phone won’t boot even after I restored my backup. I followed these instructions (forum.xda-developers.com/nokia-8/how-to/guide-restore-nokia-to-stock-t3867646/) to flash the stock firmware, but the OST LA program keeps giving me 0xc3b9 something like tool func not ready. Can anyone help me? Thanks in advance!
- I have my bootloader unlocked, if anyone’s wondering.
EDIT: I have followed the steps with more care, and I managed to advance to the flashing process, but it gets a new error; 0xc6DA
EDIT 2: I realized I don't have critical unlocked. I can't access my unlock.key since download link expired long ago. Is there any way I can unlock the critical at this moment?

UPDATE: It's recognized as HS-USB Diagnostics 9008

You must use OST LA 6.2.8 and firmware NB1-488 android 8.1. then update via emegency download. It works on EDL mode.

It's a good new if your computer recognize 9008 mode. Your phone's main is alive. Sahara failed because your phone is in EDL mode too long time. I don't know exactly how to fix it. The last hint: let take out your battery and insert again. Or Press and hold vol - + power 15-20s. Good luck

Update on the whole situation:
I managed to get to the download mode, and flash OREO NOVEMBER boot image on it. It successfully booted into Pie that I previously had installed. When I tried to follow the instructions given in the quoted post, I install November OTA successfully, but when I try to install December update, it says that I should use the 488K package. After I do that, it aborts the installation because there is no driver directory found. I think “Okay, November is fine” but when I try to reboot it goes into EDL. I again managed to flash the OREO boot image, and boot again into PIE (how is this possible?)
Also sidenote: WiFi doesn’t work. It didn’t work even after the first time I flashed Oreo boot. Can anyone perhaps provide me with a stock Pie boot image? Or does anyone know any other solution?

Back to stock - the aftermath
Hi all,
https://forum.xda-developers.com/showthread.php?t=4081895
(please read first and last post)
In short: I found some sketchy Android 10 update for Nokia 8, tried it out, did not work. Tried to restore my TWRP backup, did not work. Tried to bring back stock firmware via OST LA, did not work. I then flashed stock Oreo November 2018 boot image, and got into my Pie, but WiFi wasn't working. I then flashed pre-Magisk-rooted pre-TWRP-installed boot image, and WiFi works. However...
When my phone boots, it boots with Android logo instead of Nokia's
My phone is detected as Dual SIM, even tho it is not.
When I try to flash OTAs via TWRP, it doesn't work
I am looking for a solution on how to remove the Dual SIM problem and how to make my phone again boot with a classic Nokia logo. Any help? Thanks in advance!

[GUIDE] How to unbrick RN8 (won't boot only backlight turns on for a second) using EDL

Hi all, after lots of trial & error, I would like to share how I managed to unbrick my Redmi Note 8
original thread: https://forum.xda-developers.com/t/need-redmi-note-8-firehose-without-authentication.4031513/
many thanks to dxD7 who provided valuable info on how this worked for him
WARNING: this process requires you to enter EDL mode which means you have to separate backplate and short 2 pins on motherboard so USE AT YOUR OWN RISK! since its not quick&easy solution yet.. thanks Xiaomi!
Symptoms:
while pressing power button , the display backlight will turn on for approx a second and phone will vibrate and then turn off
while pressing power+volume- button, the phone will do the same as above but will show fastboot image for a second too
while phone is connected via cable its backlight will turn on for a second and thend turn off repeatedly..
tested on ginko, batch 2020.11 - but should work on other (older phones as well) not tested on 8T-willow but might work - some mention about it is in original thread
note that there is different kind of brick where after turning on the phone only the LED light blinks - it wasn't tested on that situtation but you can try it and pls let me know.
What you will need
clean windows without any previous ROM-flashing or android development drivers is recommended as it looks like windows is unable to fully uninstall previous drivers - they will reappear once device is connected
download xiaomi flash tool 20200314 from https://xiaomiflashtool.com/download/xiaomi-flash-tool-20200314
download QPST v2.7.480 from https://forum.hovatek.com/thread-22467.html
download fastboot ROM named ginkgo_global_images_V11.0.12.0.PCOMIXM_20201119.0000.00_9.0_global_37804edbcb.tgz from https://bigota.d.miui.com/V11.0.11....XM_20201001.0000.00_9.0_global_389eff34c9.tgz
prog_emmc_firehose_Sm6125_ddr.zip from attachment
STEPS:
unpack ROM (for example to Desktop)
unpack prog_emmc_firehose_Sm6125_ddr.zip and place prog_emmc_firehose_Sm6125_ddr.elf from .zip into your unpacked ROM folder: /ginkgo_global_images_V11.0.11.0.PCOMIXM_20201001.0000.00_9.0_global/images/prog_emmc_firehose_Sm6125_ddr.elf (overwrite the old one)
run QFIL.exe and set it up similiarly like in this video (i know it's for 8T and but same principle is applicable here)
leave QFIL.exe running, you will need it later
now the tricky part. remove backlplate, connect phone using USB cable (prefferably stock cable that came with the phone and into USB2 slot) and short these 2 pins to get into EDL mode

}
you should hear windows sound of device plugged in. check in the device manager - it should report as unknown device QUSB_BULK_CID:XXXX_SN:XXXXXXXX
now run xiaomi flash tool 20200314 and it will prompt to install drivers so click Install and check if your unknown device now reports as QUALCOMM HS-USB QDLoader 9008 (if install process happended too fast and you cannot see the driver (this happened to me) please remove anything from MiFlash20200314\log folder and try again)
once the driver is installed, QFIL should show QUALCOMM HS-USB QDLoader 9008 instead of No Port Available
click on Download Content to flash firmware
now my 1st flash failed - I got Sahara Error, so I disconnected the cable, pressed all 3 buttons on phone for ~10seconds until screen blinked and phone vibrated
I connected cable again, shorted these 2 pins to get into EDL mode, pressed Download content again and now it worked (took few minutes) and Download Succeed
hold all 3 buttons for ~10seconds and phone should start up
to my knowledge the error you will get the most in QFIL is Sahara Fail. according to the internet, this might be due to many reasons (bad cable, bad usb port, antivirus running, wrong firmware or firehose or wrong driver but in my case it was the wrong driver - internet is full of various qualcomm driver but I had succes only with the one included in xiaomi flash tool 20200314 ) for more troubleshooting please use for example https://www.nirsoft.net/utils/usbdeview.zip check if your driver's version is same as on the attached image (2.1.0.5)
No reboot nor enabling unsigned drivers, running QFIL as administrator, disabling antivirus was needed in my case.
Maybe some of these steps are unnecesarry, maybe this guide can be written more understandably - sorry for that - i wrote is asap so I won't forget anything I did during process. Please feel free to modify it or I will try to improve it in the future if I brick my phone again and have more knowledge about it..
and I also need to figure out how to stick backplate to phone again so that it can be removed if needed while still preserving some kind of waterproof function..
EDIT: bricked my phone 3 more times aftrer trying to install RR but was able to recover from all of them again
UPDATE:
user Elinx stated that this happens only with 11-2020 batch and flashing FW 12.01 with recovery. So let's hope it won't happen on other batches..
It is also mentioned here (hope it helps):
see in this topic
and here too

I live in canada and I found a 2mm double sided tape on amazon for like 10$ made for electronics. I think that's what I'll buy, and I can come back with an update if it's good or not. https://www.amazon.ca/dp/B00BXYWXY8/

thanks either that or I'm thinking about B7000 glue which looks like many people are using for sticking battery cover

Thank you, I revived the Redmi Note 8 in the way you share.

u re welcome. good to see it works!

Hi, i will follow this process, but i have a different kind of brick, it`s completely dead, not vibrate, no led, nothing. The only sign of life is the sound in my pc when i connect/disconnect usb cable and i can see it in MiFlash as "COM3" and "QUALCOMM HS-USB QDLoader 9008" in QFIL.
It will work?
PD: i brick the phone after update to MIUI 12, ye i dont know how

I have the famous "Sharara" error, what did you do to solve it?

So i finally unbrick my phone! It´s alive ahaha. Thanks a lot, you are my new god.
The reason why i get Sahara error was becouse i have a old version of QPST/QFIL

Fantastic work. I waited about 50 days for the same so the official service could do this.
I'll bookmark your work if I need it again in the future
Cheers man. Thanks.

Nice work !
i saw a tutorial on how to enter EDL mode without opening the phone but i can't find it anymore
its here on xda, if you find it update your tutorial

I haven't tested this myself, but with unlocked bootloader you maybe can use the fastboot command:
fastboot oem edl
I haven't seen this with RN8 on XDA, but with RN7 Pro and Poco X3

thanks a lot, got my phone back.

now the tricky part. remove backlplate, connect phone using USB cable (prefferably stock cable that came with the phone and into USB2 slot) and short these 2 pins to get into EDL mode View attachment 5209521
you should hear windows sound of device plugged in. check in the device manager - it should report as unknown device QUSB_BULK_CID:XXXX_SN:XXXXXXXX
now run xiaomi flash tool 20200314 and it will prompt to install drivers so click Install and check if your unknown device now reports as QUALCOMM HS-USB QDLoader 9008 (if install process happended too fast and you cannot see the driver (this happened to me) please remove anything from MiFlash20200314\log folder and try again)
once the driver is installed, QFIL should show QUALCOMM HS-USB QDLoader 9008 instead of No Port Available
click on Download Content to flash firmware
now my 1st flash failed - I got Sahara Error, so I disconnected the cable, pressed all 3 buttons on phone for ~10seconds until screen blinked and phone vibrated
I connected cable again, shorted these 2 pins to get into EDL mode, pressed Download content again and now it worked (took few minutes) and Download Succeed
hold all 3 buttons for ~10seconds and phone should start up
to my knowledge the error you will get the most in QFIL is Sahara Fail. according to the internet, this might be due to many reasons (bad cable, bad usb port, antivirus running, wrong firmware or firehose or wrong driver but in my case it was the wrong driver - internet is full of various qualcomm driver but I had succes only with the one included in xiaomi flash tool 20200314 ) for more troubleshooting please use for example https://www.nirsoft.net/utils/usbdeview.zip check if your driver's version is same as on the attached image (2.1.0.5)

No reboot nor enabling unsigned drivers, running QFIL as administrator, disabling antivirus was needed in my case.
Maybe some of these steps are unnecesarry, maybe this guide can be written more understandably - sorry for that - i wrote is asap so I won't forget anything I did during process. Please feel free to modify it or I will try to improve it in the future if I brick my phone again and have more knowledge about it..
and I also need to figure out how to stick backplate to phone again so that it can be removed if needed while still preserving some kind of waterproof function..
EDIT: bricked my phone 3 more times aftrer trying to install RR but was able to recover from all of them again

From what I understand, this looks a specific problem with Board ID 3.29.
The reason could be that only the same Miui version or higher and same region can be flashed than the one with which the phone came.
Also flasshing without battery connection could help.

I too had this flashing backlight problem and found the reason why this happens.
It is only the november 2020 batch (11-2020) which has Miui 11.0.11
This batch can't be flashed with recovery to Miui 12.01 or 12.01 FW.
If you do this, your phone get this brick, while there isn't a single error with twrp flashing.
No fastboot, No recovery, No system anymore
You need EDL testpoint and patched firehose file to revive your phone.
With twrp, Flash Miui12.02 or higher , you will never notice this problem.
