I have tb-x304f that I unlocked and flashed TWRP and then tried three different custom roms that all failed to boot. I am trying to restore stock firmware but it is not working. I have installed firmware with qdl in Linux and with QFIL and Lenovo Rescue and Smart Assistant in windows. All three methods report success. After allowing time to boot it ultimately boots into 900E Diagnostic mode after a brief stint as MTP device. The boot logo shows on display, the little Lenovo tone chimes and a progress bar with powered by Android starts. Bar gets about one third of the way and it goes black, then it's 900E Diagnostics again. Use hardware buttons to put it in QDLoader 9008 mode and flash again, same results every time.
I am lost, with successful flashing with no errors, but it won't boot. Do we have a Qualcomm expert in house that can help me figure this one out ?
Hi, first of all, sorry for my English, I don't write it very well.
I have a Lenovo Tab4 A 10 x304l actually it is in bootloop, because I tried to install a Custom ROM and never boot it. I tried to install two stock ROM, that I download to diferent sites, but the tablet after a minute reboot it's self continiusly. I need your help, if Is possible, because I don't know what to do.
My WhatsApp Is ±5354161215, I apreciate any help.
Thanks very much...

Accidentally bricked my phone while trying to unlock the bootloader on my phone. I was doing this in an attempt to root my phone again after removing the root in an attempt to update Oxygen OS. After TWRP was unable to flash the update I gave up and tried to root the phone again using kingo root but kept failing. I checked whether or not the bootloader was locked and sure enough it was but after attempting to unlock it again, the phone was bricked and could only go into fastboot mode. Flashing the stock OS didnt work since the bootloader was locked. I tried using a unbricking method posted to oneplus forums that invloves downloading qualcomm diagnostic drivers and using a unreadable download tool but couldn't find the driver the method mentioned Qualcomm 9008. After some more searching other methods were similar but used the driver Qualcomm HS-USB Diagnostic 9006. Once that driver was installed i launched the MSMdownload tool which was taking hours with no progress bar whatsoever so i decided to go to sleep. I woke up to an unreadable notification from the download tool and my phone's battery was dead. The phone wouldn't go into fastboot mode but was still being detected in device manager. All the phone responds to is the power button and volume down button being pressed which just causes the phone to display a low battery notification and then stops charging a minute later. I then tried using an unbricking method that involves installing the qdloader 9008 driver and running a program called QFIL but this method failed to unbrick the phone. Is there any way to factory reset my oneplus 2 and put the stock OS back on to it? please keep in mind that the bootloader is locked. i cant post links to the methods i used as the site wont let me
My phone was really slow and it was lolipop. When i try to open same apps it stucked. Then i decided to install cm 12.1. I did it before. My phone was rooted and installed TWRP.

Thank You ?
I am also trying my best to recover the phone and i will write here so that anyone who is facing this issue can recover his/her Phone.
No Solution found for this.

You have to send your Lenovo K6 Power to Lenovo Service Centre and get your Motherboard replaced.
If your phone is in guarantee then you will get free replacement no matter if your phone is rooted but please don't tell about root to them otherwise they will charge money for your small mistake.
what happened?
Do a new install

Boss it seems that you have hard bricked your phone so it means it's first boot has been corrupted there is no chance as first boot is mandatory to flash any file, there are some tools like octopus, or Medusa box, they can repair your boot then the phone can be used its just an outside chance 5o get it in workable condition look for some person or Repairing person have this boot repairing gadget,
If this fails too or you have messed up very badly then, last option is mother board replacement, there is no software option to repair by yourself
Help please..!!!!
:crying:

Did you find any solution for this, present i'm facing same issue, please tell me if you have any solution for this...
i attempted to root my zte maven 3 with zpst for at&t and when the device went to restart the screen stayed black and no matter what key combinations i try i cannot get the screen to turn on. The only thing the phone does is connect to the pc and makes that connection noise. it connects as Qualcomm HS-USB QDLoader 9008. does anyone have any advice or suggestions that might help
Did you make any partition backups in QFIL by any chance? If not, I have no idea how one would go about fixing it. What's your bootloader version? I can try to give you my partition backups and you can try flashing it and seeing if it'll boot.
Tbh I should write my own rooting guide, because the existing methods are, quite frankly, ****ty and dangerous. To anyone reading this, please open QFIL and make a backup of all of your device partitions before messing with anything; this is basically creating a bit-for-bit backup of the storage itself, such as the persist partition, userdata, system, etc. I had to buy a for-parts Maven 3 from eBay because I bricked my Maven 3 using the same guide...
And don't use ZPST from now on. You don't need it. Everything can literally be flashed as a partition in QFIL easily. This is how I safely flashed a Magisk boot image (partition) and half-working TWRP recovery partition.

Your device is in EDL mode. It's the only mode that connects as Qualcomm HS-USB QDLoader 9008, and EDL mode doesn't display anything on your device screen. Just take the battery out for a second and you should be able to boot normally.
I'm going to post a new thread in this forum as soon as I send this, where I'll run down the steps I took to achieve root on my Maven 3 just this morning. I've powered off and booted up about 5 times since rooting and it's still rooted.
I have edl mode no boot no screen no lights, what do do next. I tried removing battery no luck

I am unsure of what you can do because iirc i faced the same issue. I have full partition dumps for my current maven 3, some of which (except for example persist) I can send and you can try flashing it using QFIL since your device sounds like it's in EDL mode
I was on A11.1.1.1 , when I decided to root my device. Tried to install Twrp but failed, then unlocked boot loader and flashed magisk using Adb from my windows 7 desktop. Phone restarted, went into bootloop, then restarted naturally - however I couldn’t turn on Wi-Fi. Downloaded SuperSU, which showed device was rooted. In an attempt to revert back to stock os, I flashed another boot image, and phone went into continuous boot loop. So I searched the web and downloaded Qualcomm hs-usb QDloader 9008, and MsmDownload tool v 4.0 in an attemp to unbrick my device and installed them. However, my desktop doesn’t recognise my phone as Qhusb_bulk or as Qualcomm qhusb qdloader9008 in devicemanager. So I m unable to use the MSM tool to un brick my phone. Tried reinstalling the drivers on desktop , but the phone doesnt show up on device manager still. Only shows up as “pci simple communications controller” under other devices.
When i turn on my phone, it shows the OP logo going round and round for 5mins, then the screen goes blank. If I keep the power off button pressed for quite sometime, phone restarts into boot loop again. Can’t get into boot loader, nor does adb on my desktop recognise the device.
i m at my wits end as to how I m gonna unbrick my phone, as this is my primary phone. Kindly guide me step by step as to how to unbrick my OP6t. Any help is appreciated.

When you get it to reboot did you try holding volume down as it starts? Should get you into recovery then bootloader.
Also get magisk to root rather than SuperSU. You can install twrp from magisk in oos with the correct installer but first you have to root correctly with modded boot.img. Can make your own or get from the one post in here. I'd suggest getting the newest oos also.

Probably need to flash a stock boot of 11.1.1.1 to unbrick. You can try booting to the newest twrp from fastboot I'm not sure if it works anymore.

Couldn’t fastboot into twrp, since device got corrupted while trying to flash multiple things. Thankfully while tinkering, my desktop recognised my device as qhusb qloader 9008, and all I had to do was boot my device into edl mode (which was also a pain tbh!). After trying numerous key combinations and timing it perfectly, device booted into edl and I could use the msm download tool to unbrick my device. Now device has rebooted into iOS 10.3.5 (same version as msm tool version) and I have somehow breathed a huge sigh of relief that my device could be resuscitated. Will be updating to 11.1.1.1 now (I see the latest is 11.1.2.2) and setting up my device now.
Thank you a lot for looking into my issue and suggesting solutions. In my younger years, I was a technology enthusiast and often rooted/flashed, but have pursued medicine since then. Now am out of touch completely to the tech scene and it was a grave blunder on my part to have used my primary driver to try and root/flash again.
Have a great day, my friend and please know that it means a lot to me to have received help from the community.

This happen to me several times and the first time it happened I thought my phone would not be unbricked after numerous attempts with the msm tool!
My issue was that my phone was a renewed amazon phone and amazon listed it as a unlocked international but it actually was a t-mobile variant and when i downloaded the correct msm tool with firmware it worked!
You need to get the phone into edl mode. For edl, when phone off press both volume buttons and plug in the usb while connected to your pc and the qualcom driver should pop up in device manager. After that finding the right msm firmware will be your next issue but with enough searching you should find it!
Let me know your progress with the driver and I can try and post some links to different msm firmware for the oneplus 6t!
