Unable to restore stock ROM via EDL + MiFlash/QFIL - Xiaomi Mi A2 Lite Questions & Answers

Unable to restore stock ROM via EDL + MiFlash/QFIL - Xiaomi Mi A2 Lite Questions & Answers

I've been trying to flash the stock ROM to my older A2 Lite phone, but for some reason I can't get the images flashed at all. The bootloader is locked and can't be unlocked since both recovery and system partitions are glitched, therefore, the only way to get it would be via EDL pinout shorts and using Miflash tool, however the flashing process gets stuck like this when we should be seeing status changing like in this video.
The drivers are apparently fine and the Qualcomm serial port is up and running nicely, I've used versions 2019.12.6.0 and 2020.3.14.0 of MiFlash and these are the images I'm trying to flash either one of them:
Code:
daisy_global_images_V9.6.11.0.ODLMIFF_20181112.0000.00_8.1_8028e3bf1c.tgz
daisy_global_images_V10.0.3.0.PDLMIXM_20190114.0000.00_9.0_e8d8d4a6d0.tgz
daisy_global_images_V11.0.7.0.QDLMIXM_20200617.0000.00_10.0_7d0ffb82ac.tgz
As a last resort I've tried QFIL v2.0.2.3 but it is also failing to switch to EDL an returning logs "Failed to Switch to Emergency Download mode" and "Fail to find QDLoader port after switch". Drivers have been re-installed multiple times and PC been rebooted quite a few times too. Anyways, literally ran out of tricks and any help would be greatly appreciated.
Here's the phone getvar output for reference.

Bricked Lenovo Vibe shot z90-7, no edl, fastboot twrp and locked bootloader.

I got a lenovo vibe shot z90-7 which was using Android 5.1. I found an upgrade rom on needrom to 6.0. I flashed it using qfil (qualcomm flashing tool) and it went all right, all functional. But I also wanted to unlock the bootloader and install a twrp (I found a procedure and twrp image on a russian forum). I followed the steps but it didn't work, I still wasn't able to unlock the bootloader. Thus, I was not able to enter fastboot anymore: from adb I was typing "adb reboot bootloader" and the device would reboot normally, not in fastboot mode. I decided to change to another rom (from needrom) which was claiming would allow you to unlock the bootloader. So, without hesitation I flashed it in qfil (edl mode) and it went all right, but I got stuck in boot loop. After the splash screen, the device shuts the screen off and does a long vibration and stays like that. If I connect it via usb to my pc I get a some "need to format drive" alerts, and in qfil I see "Qualcomm HS-USB Diagnostic 9006 (COM5)". If then I try to flash the rom I get this log:
Code:

It's seems like I need to get in Edl mode first, but I cannot use adb and pushing vol+ and plug the usb at the same time (or a little bit first one or the other, I tried all) does't do anything but booting the device normally.
I also tried getting in fastboot mode (keep vol- and power button) but it doesn't work.
I read of an "engineering mode" by keeping vol- on boot. It does something, the screen becomes black, but it's on. On my pc the adb driver comes in in the popup, like if I'm in fastboot or adb, but on "fastboot devices" I can't see anything, while on "adb devices" I see a device, which is "? unauthorized". Strange to me, I can't do much with it since it's unauthorized and the screen on the device remains black. And after a few seconds (about 30) it gets back to long vibration and screen off state.
I can get into the stock recovery by holding vol+, vol- and power, but it's a very poor recovery. All I can do is reboot, shut down, wipe data and update. I tried to use "update" and put a zip file of an official rom downloaded into the sd card and named "update.zip" as suggested by the recovery, but I get an error (with no technical information about what kind of error), so no luck with that either.
I tried to force the qualcomm driver from "Qualcomm HS-USB Diagnostic 9006 (COM5)" to "Qualcomm HS-USB QDLoader 9008 (COM5)", then tried to flash using qfil, but I still get an error, even if this time is different:

I finally tried to download the rom in .qsb format and get in engineering mode again, but the screen remains black and no sign of flashing possibilities.
Please help, I tried everything it came to my mind.
I also tried with miflash, but still got errors...
Thank you

Hello, did you solve the problem? i have the same as you....
regards

Hi guys.
I had the similar problem few moths ago. I tried to remember what i've done to fix it, but I don't remember all things, I hope this steps helps to find the solution.
Check this:
-Use Windows 7 (I tried with Windows 10 and always appears some errors)
-Use original miniUSB cable or good quality cables
-Install Lenovo Usb drivers
Turn ON phone and press Vol+ and Vol-, hold 3 seconds
If you cant enter Recovery mode (because is corrupt or bricked), phone will vibrate for 1-2 seconds and screen keep black. Now connect USB cable (check drivers, also if Qualcomm HS-USB QDLoader 9008 was installed)
Once you done, use QSFL or MiFlash (but not 2016 version!, never works to flash)
NOTE: I had some problems with my desktop computer with Windows 7 but no problem in laptop. So check it in more than one...
Good luck.

How I fixed this
I fixed it installing a update.zip via recovery (vol + plus vol - plus power) I found here
http://forum.xda-developers.com/android/development/vibe-shot-6-0-update-root-xposed-t3409989
This not fixed the phone , but allowed me to unlock bootloader entering in fastboot mode (vol + plus vol - plus plug usb) using this
http://lenovo-forums.ru/topic/18149-lenovo-vibe-shot-разблокировка-bootloader/
Then I was allowed to install TWRP as explained here
http://lenovo-forums.ru/topic/18150-lenovo-vibe-shot-расширенное-рекавери-twrp-by-sevenmaxs/
Then I was able to go to TWRP terminal and type
reboot edl
Phone went into downloader mode and I was able to install this rom with QFIL
http://www.needrom.com/download/lenovo-vibe-shot-android-6-0-1-1625-encn-unlocked/
and I restored NVRAM with a qcn file I found in Ebay after putting the phone in diagnostics mode. Then I changed imeid, meid and esn to the original ones I found in the box. Phone fixed.
Just note that this file was for a Z90-7 rom and it will not work with a Z40a20 rom.
Hope this helps someone.

Hi, did you slove the problem? Same situation with me. But I managed to install twrp ( Chinese) but I can't install any rom .. After successful flashing it reboot with lenovo logo, then long vibrates.. When I connect it to PC. It show number of partition and need to format popup.. I tried different ROMs.. All via twrp. I don't use miflash or qfil.. If you have solved it please share how. Thanks.

i know how to enter in edl mode in z90-7 or z90a40
Hello
This is nisar I successfully entered in edl mode and flashed rom to know the procedure pm me on +919743392420 WhatsApp

Bricked Vibe Shot - multiple partitions in device manager - no edl
having read all the above I'd like to share small info once again, it is all about correct qualcomm drivers, you can get them from androidurdu.net, do not search on the site but click on mobile drivers then scroll down and download qualcomm usb drivers.zip . unpack and use "checked" folder within the zip, they are signed and work on any windows including 10th. You see, your brick might be having an edl times, but PC doesn't know without proper drivers installed. You might want to remove all earlier/bad driver versions, for example try sigverif command or just install below qualcomm drivers and try away.
1. connect phone with good usb cable, 2. press power button till it shuts, then release power button and press volume up and down same time and phone will enter edl mode itself almost instantly, if you had twrp installed then it'll enter there, if so run from terminal "reboot edl"; keep device manager open and comm tree will appear along.
other way is via adb reboot edl command, if fastboot doesn't work, or fastboot reboot-edl
on miflash when refreshed you see the short port name and the number like com4 or 3. now it's time to flash, but the last proven flash I did with QiFL, Miflash works as fine.
i used latest international marshmallow version. after first boot, within dev mode unlocked oem + enabled adb and connected to PC with phone turned on in order to accept handshake prompt.
unlocking bootloader is easy via adb command: adb reboot bootloader, then: adb bootloader unlock-go .
all files are available online via some russian speaking forum, you just need to install twrp, then place su.zip onto phone (I copied on internal memory), boot into twrp and flash; if clean - no errors flash then you got neatly rooted marshmallow phone.
my struggle with bricked vibe shot was worth it. earlier I noticed cpu was running high, all cores all the time. also many google apps which I wanted to eliminate for draining the battery and uploading stuff all the time.
right after flashing su.zip boot into phone and install kernel adiutor from play store, then take control of how your 8 cores behave. I discovered the minimums were set at 800+Mhz so I dropped them to 200, then below within cpu section enabled all "disabled" options for boost + enabled "ondemand" + plus few more. You got to understand the process and enjoy tuning your phone your way.
I've charged my vibe shot 3 hours ago and was randomly chatting on whatsap until now and I have 73% battery. Day before yesterday before the bricking, full charge would not last more than 3 hours, incredible battery performance thanks to "adiutor" .
One more important thing, use correct rom version for your phone because of advanced camera and specific drivers camera won't work well.
Names of files used to make my phone a super hero:
1. adb-setup-1.4.2.exe
2. Miflash_140509.exe
3. Qualcomm_USB_Drivers.7z via androidurdu.net
4. TWRP-3.0.2.0_Z90a40_by_SevenMaxs.rar - has .bat files inside; enter bootloader mode and shoot
5. UPDATE-SuperSU-v2.76-SYSTEMMODE-PRO.zip (I pay for my apps including supersu pro)
6. Z90a40_Android-L_unlock_7M.7z , or use command line via adb shell.
7. Z90a40_S363_160625_ROW_QPST.7z - latest intl Mashmallow Os , to make it more perfect download marshmallow google dialer - patched.apk.
8. QPST / QIFL , used to flash the above rom
I'm not a pro so small mistakes are acceptable, I hope.
ciao.

Hey, I have the same problem as you, trying to do the step you did, but I get stucked at the first step,
I cannot find the file UPDATE.ZIP in the page from your link....
Could you help?
Thanks

Sorry if it's reviving the thread but i found a way to unbrick the device from this state. Not sure if will work for all models because this one was a really weird one (almost all button combinations were different than any described on the internet). So my phone was from China (Z90-7 - later it showed that it's a Z90A40 and I had to flash that firmware) with a international chinese ROM and it god badly bricked (no edl, no lenovo recovery, locked bootloader etc. etc.). Now, when holding [vol+]+[vol-]+[pwr] (usually recovery mode according to the internet) it went into the Qualcomm 9006 diagnostics mode that shows a million partitions. There was no way i could get it into edl mode but there was the so called factory mode that is accessed by holding [vol-] and plugging in the usb before it vibrates. Through this I managed to flash firmware in .qsb format from a SD card and successfully unbricked the phone that I almost threw into the bin.
1. Check if your phone has "factory mode" [vol-]+[pwr] then release [pwr] or hold [vol-] while inserting usb cable.
- make sure to try different combinations, the button combinations on my phone were much different than what I mostly found on the internet

2. Download Vibe Shot firmware in .qsb format (Google it, the phone will warn you if it's not the right one (A40 or -7))
3. Copy the .qsb file into SD:/sdfuse
4. Insert the SD card into the phone (maybe a restart will be needed for it to be detected, you should see a message saying "DEV: External storage" when you select sd flash)
5. Select "SD update" and follow the instructions.
I hope this helps someone who can access the factory mode. This is so easy and I couldn't believe that there is so little information on flashing it this way.
Good luck.

i wonder how do you change HS-USB Qualcomm 9006 become HS-USB Qualcomm 9008?

Sort of bricked G4, rebooting download mode, no fastboot recognition nor TWRP

Hi all,
I have tried my luck in two different threads already and did hours of research but thus far, no success. I hope somebody can help me.
I installed the official Nougat (V29A) update and after that the Oreo AOSCP ROM. Everything went (seemingly) fine, Oreo was working. I wanted to reflash Oreo to get rid of some Google Apps, but the problem then was, that I could not reboot into TWRP. The only recovery mode is the Android recovery and I cannot reset the phone, neither use ADB sideload, nor do anything else (unknown fs_filetype error). Only thing that is working, is to enter the fastboot mode, but my laptop does not recognize the phone while in fastboot mode.
I also tried resetting the phone to factory defaults from within Android (back when it was still booting up) and now my phone is stuck in a bootloop which ends in the (useless) Android recovery mode.
At first I thought reflashing the stock kdz would not be a problem. I am able to enter download mode, but it only stays in download mode for about 15 seconds and then reboots itself. LGUP or LG flash tool, don't recognize my phone in that short amount of time.
I tried the above mentioned solutions on OS X, Windows 7, Windows 10 as well as FWUL. No system recognizes my phone.
I really am at my wit's end. Any help would be appreciated.
If any further information are needed, I am happy to provide these.

I changed following in hidden menu NT Code, changed as below NT Codes with respect to firmware region... Rebooted after confirmation "NT Code Write OK" message.
V29a Firmware NT Code:
"1","FFF,FFF,FFFFFFFF,FFFFFFFF,11"
V20h Firmware NT Code:
"1","FFF,FFF,FFFFFFFF,FFFFFFFF,51"
Checked in both above firmwares..Worked flawlessly on my h818p...No more annoying message on every boot.
Software Version in about/ settings also changed to region exp. 20h-DS2-XX to 20h-ESA-XX upon reboot.
Is DS2 appears when cust mismatch..?

MiFlash: Device in EDL not showing up in MiFlash device list.

Hi,
I was trying to flash Lineage OS on my Whyred, and installed non-ARB ROM over MiUi 10 and my device is now bricked.
I can see my phone in EDL mode, as I can see "Qualcomm HS-USB QDLoader 9008" in the device manager.
I have also installed all the drivers from MiForum thread-784616-1-0. (I don't have right to post complete link)
Even after restart and power cycling the phone, my device does not show in MiFlash tool, and I get "Length cannot be less than zero. Parameter name: length" error. I have tried three different versions on MiFlash tool.
I am on Win10 64 bit
I have unlocked bootloader with TWRP installed before the brick happen.
EDIT:
I tried QFIL methods but it was unsuccessful.
Qfil tool detects the phone without issue, but flashing fails with the following error:
Code:
ERROR: Only nop and sig tag can be received before authentication.

1. none of the custom rom has ARB switched on! how did you brick your phone by flashing Linage??? I cannot understand
2. you cannot JUST go in to EDL mode with RN5pro since Xiaomi has removed the pressing volumes and power button 30 seconds to get in to edl mode! you have remove BACK PANEL of rn5p and short the testpoints with metal & plug the usb in with pc in order to ender edl mode!
3. even if you enter in edl more! miflash will ONLY flash if your MI account has been authorised from china!
now what exactly is your device state? can you reboot enter in fastboot mode?
fastboot roms cannot be placed in LONGGGG paramiters! put it in C drive and rename folders to smaller.. like C:\1 and put all the unzipped Tz files here to flash!
if you cannot flash by mi then you should consider Qualcom Qfil flasher! , RN5p is snapdragon device and can be flashed with QFIL!

I don't know how it got bricked AFTER installing Lineage OS.
Current situatiuon
1) Mi Flash tool does not list/detect my phone even though I am in EDL mode.
2) Qfil tool detects the phone without issue, but flashing fails with following error:
Code:
ERROR: Only nop and sig tag can be recevied before authentication.

Hello everyone, a couple of months now are also thanks to you in the world of modding. Yesterday (i have a Xiaomi Mi A2 Lite) during the installation of a custom ROM using ADB, typing in the fastboot command "erase system", I wrote erase a_boot for error because before I was reading a post about it and I wrote it. Yes I know, I was too stupid. Result? The phone does not start up either in recovery or in fastboot mode, and from the PC it is recognized as COM port. I have already documented about it and tried to flash everything with the Qualcomm tool after installing the drivers but nothing. I tried the EDL by activating it manually to unlock port 9008, but still during the flash gives me error. I tried everything, do it all over again in a newly formatted and clean PC from any other driver, but nothing. During the flash, even if I put the firmware in the same directory, it still gives me error. Guys I'm desperate please. I do not know what else to do. I hope to receive your answers

Hello,
If you use Windows write it in CMD in Adminastrator,
Code:
bcdedit /set testsigning off
After that try flash via MiFlash a stock rom. IMPORTANT, Select clean all only.
If this not work use a Deep Flash Cable,
- Shutdown your phone
- Connect the usb cable to your computer
- Start pressing the button
- Wait 10 seconds
- Connect the cable to your phone
- Wait 5 seconds
- Stop pressing the button
Normaly the led flash, You are in EDL mode
Flash a stock rom via MiFlash with clean all option.
To leave EDL mode you need to press on power button 20 seconds.
PS: Soory for my very bad English

Oneplus 7T bricked in EDL mode (Firehose GetUsInfo Failed)

I was using my oneplus 7T normally without root and with bootloader locked when it decided, out of nowhere, to fall into "Qualcomm Crashdump Mode". When I tried to reboot it, it just went into "Qualcomm Crashdump Mode" again. So I went into fastboot mode, unlocked it, and flashed an european ROM from here: https://sourceforge.net/projects/fastbootroms/files/OnePlus 7T/ . However when the device tried to boot up it just went to "Qualcomm Crashdump Mode" again, so I tried using "MsmDownloadTool" (hotdogb_14_E.21_201105) ( https://forum.xda-developers.com/t/...l-to-restore-your-device-to-oxygenos.3994835/ ) and it worked, but this time when the device attempted to boot up it went into EDL mode and the bootloader was locked and when I tried to unlock it, it gave me an error related to "OEM unlock" not being enabled in developer options. So I tried using "MsmDownloadTool" (hotdogb_14_E.21_201105) again, and somehow this time it actually booted up. Still, after 10 seconds it went into EDL mode AGAIN (note: at this point, I couldn´t get out of EDL mode, I could only boot into anything else after the battery died, in the first boot). So I downloaded another ROM for msm but this time it gave me the error: Firehose GetUsInfo Failed, and the phone seems to disconnect and reconnect. From here I tried multiple ROMs for msm and always received the same error, even using the one I used originally. (Note: I have been waiting for my battery to die for 5 days, and it still has power; also tried removing the battery )

Sorry if the description was too confusing, long, or had any mistakes in terms of English. I am just trying to be as complete as possible.

The same arround here.....
Any solution?

Sounds like hardware failure (memory ram chips). Buy a cracked 7T and swap motherboard

First of all thank you for replying! I really appreciate it. Second of all, I did some research considering your reply and I stumbled upon this post: https://forum.xda-developers.com/t/oneplus-6-possibly-soft-bricked.4297489/ . What I did after seeing it was, I vacuum sealed my phone in a bag (to minimize condensation) and place it in the freezer for about 20 minutes I tried booting up the phone but it just went into edl mode again. However this time when I used MSM download to it actually was able to complete the whole process. The phone still didn't boot, but now I can enter fastboot and recovery. All this leads me to conclude that you are right.
