Qualfast Flash Tool for Qualcomm devices (smartphone&tablets)

* [ Not Confirmed yet, especially for Lenovo Tab 3 Plus models - Works only with Qualcomm devices generally,smartphone&tablets!] :confused:

_Νote: Qualfast Flash Tool for any Qualcomm device: (has not been tested by me because I do not have the device anymore,but it is the easiest tool generally for Qualcomm devices!(smartphone & tablets)

_Qualfast Supports : Windows XP / Windows Vista / Windows8 / Windows8.1 / Windows10

_ Qualfast Tool all Versions : https://androidmtk.com/download-qualfast-tool
_How to Flash Stock Rom Using Qualfast In Qualcomm devices : https://androidmtk.com/flash-stock-rom-using-qualfast

If someone tried it,he can tell to us his opinion & if Qualfast worked in Lenovo Tab 3 Plus models
* I have no responsibility for what anyone does on his device!

Hi guys,
Firstly thanks for your great work on getting these tools and all the translations.
An official update from Lenovo brick'd my device, so I am trying to reinstall the official ROM, or any ROM.

I had the usual sahara errors, but was able to get the boot loader to transfer using QFIL 2.0.1.1 as described in the QPST method. However I am now getting stuck with Firehose unable to see the device...
I am using the TB-8703F_S000030_170307_ROW_QFIL image.

Any tips on where to go from here? I'm not super familiar with the tools in question, so may just be doing something obvious wrong.

the whole world is my home ?
Υou are not putting device in download mode in proper way.(IDK your pc but maybe need the correct drivers-Qualcomm HS usb)
First setup QFIL, set all settings, provide path of binaries and xml...read carefully in OP & see the screenshots...

1) go to OP & read carefully : 3)Disable driver signature enforcement on Windows 10/How to disable Driver Signature Enforcement
(disable driver signature & reboot your PC) *this needs before anything
2) Qualcomm HS-USB QDLoader 9008 : go to OP & Install these drivers
3) https://androiddatahost.com/np4wq ( extract file & use QFIL that included inside > https://androidmtk.com/use-qualcomm-flash-image-loader-qfil )

_[take the correct file from OP for your device,read carefully & follow the steps]
I do not have the device anymore,I can not help more...

Quote:
A test point is detected (wi-fi version of the tablet, it may work on lte).
So, install QPST, drivers, download firmware, prepare QFIL for firmware (the instruction is in the subject), when connecting, the brick is defined as HS-USB Diagnostics 900E, disconnect usb cable, disassemble the tablet, turn off the acb, tweeze the pin specified in the photo on the iron frame, hold, do not release the jumper and connect usb, then connect the acb, as soon as the computer determines HS-USB Qdloader 9008
release the jumper and click download in QFIL.
what does "acb" mean? I'm trying to resuscitate the tablet, but it persists in staying in "HS-USB Diagnostics 900E", but probably because I do not understand what is this "ACB" mentioned
is it possible to flash the twrp or if I can make it go in "the HS-USB Qdloader 9008" I will be forced to put the stock rom?
thanks a lot to those who can help me

I don't know. The only things that come to mind are adb (doesn't really make sense in this context) or backup battery (which i don't know if the tablet has). Sorry I can't be of more help. Good luck

thanks for the fast response and for being there anyway... it was just the flat of the battery... I flashed directly the twrp, restarted in recovery, press ''advanced'' and then ''RM Forceencrypt"... everything went very well!!
I report the steps a little more extensively:

01)install QPST
02)install drivers
03)download firmware or recovery
04)prepare QFIL for firmware or recovery, when connecting with usb, the brick is defined as HS-USB Diagnostics 900E
05)disconnect usb cable from TB-8703
06)disassemble only the back cover tablet
07)remove the cover that occludes the contact to make the short circuit
08)remove the two screws that block access to the flat battery cable
09)disconnect the flat battery cable
10)close with tweezers the contact indicated on the photo on the iron frame
11)do not release the jumper, connect usb
12)then connect the flat battery cable
13)as soon as the computer identifies the TB-8703 as HS-USB Qdloader 9008, release the jumper
14)click download in QFIL
15)Good lucky!

I cannot detect my lenovo using qfil and booting it with volume up + power button. The port is not available. I installed the qualcomm usb drivers and lenovo usb drivers but to no avail.

this is a matter of incorrect installation of drivers on the pc
did you disable driver signature before ?
try from the beginning with correct way
uninstall drivers / reboot pc / disable driver signature / Install usb drivers / Qualcomm HS-USB QDLoader 9008 drivers / reboot pc & try again to connect device - pc

Tried this as well, did not work. It works in EDL but not this boot mode.

Hello,

I try all you tricks but I can not restart my Lenovo TB-8703F tablet.
When I try to start it in "Download Mode" (Power + Volume Up), the tablet vibrates and the small diode flashes white but nothing more.
On the other hand, Recovery mode still works. But I tried to flash several ROM (lineage, CrDroid etc ...) but nothing changes at the end of the process the tablet crashes either in boot loop or starts directly in the recovery mode.

And when I was in QFIL utility and I try to flash I get this :
Start Download
Download Fail:Switch To EDL FailFailed to Switch to Emergency Download mode


Do you have a solution?

thank you in advance
