Support for OP8T: unbrick tool seems to not work, partions can't be mounted - OnePlus 8T Questions & Answers

I'm on OP8T, the current status is:
- I can access fastboot
- I can access orangefox recovery (so I could boot to EDL mode, but it seems to not work)
- I can use ADB from my computer
- I can't boot any OS
The problem: I have some partitions that seems corrupted because they aren't automatically mounted when I boot to recovery. I tried to clean data and flash crdroid rom but both operations have errors (all partitions have the error "the partition can't be mounted").
Other problem: Unbrick tool doesn't work, it seems to not recognize the device and not start the flashing. I followed the guide in the official thread https://forum.xda-developers.com/t/...l-to-restore-your-device-to-oxygenos.4180837/ but when I press volume buttons the smartphone doesn't go in EDL mode (because it's not recognized by the unbrick tool). It seems to not go in EDL mode even from recovery (using the "reboot to EDL").
Is there a way to flash stock oxygen os in order to "re-build partitions"?

Try putting your PC in test mode:
Press windows key (on keyboard) + x
This brings up a menu, click on powershell (administrative). Powershell is like a command prompt.
In powershell enter this command:
bcdedit /set testsigning on
Once it says successful, reboot your PC and then try MSM tool again.
Let me know how it goes.

I solved installing the driver manullay because the phone was recognized as QHUSB_BULK and not as QDLOADER 9008

Try also to look at this thread with proper driver installation.

[SOLVED] Problem with fastboot/recovery with TF300TG

There is some similiar threads about this, but I still haven't found solution to my problem. I also tried to post this same problem on general: (TF300TG)For All Your Jelly Bean discussions-problems, but I thought if this was better on troubleshooting.
I got problem with recovery/fastboot on tf300tg..
Background: I haven't root my tf300tg, I got 4.2.1 (10.6.2.11) and I have unlocked bootloader from Asus support and installed APX drivers to windows 7 which works with tf300tg. (even when it's not so needed?) Also I got USB debugging on.
Problem: When I press (Vol Down + Start) to get in bootloader and try to start RCK it gives me error ("Virhe" means error in finnish).

}
Second Problem: If I can't use recovery I could try to use fastboot. I downloaded ADB and tried to follow instructions but there is one problem with this. I can use fastboot only when my tf300tg is on normal mode. So I can't use fastboot in recovery or in bootloader mode. I'm not sure if I should use fastboot in normal mode (don't know if it's safe?) to install TWRP 2.6.0 (for tf300tg)
Normal mode:
APX mode/Bootloader mode:
EDIT: After 5 hours of finding, I found that reason was ADB version. Fixing this problem was download: minimal adb and fastboot program to windows.

Wpt500 wikipad rooted jb 4.2.2

Hi there, I've managed to root Wikipad on newest update
Works only on windows7 ( I used VMware ) unless you find a driver for windows8
1. Install driver in package
2. reboot PC
3. make sure you've got dev mode enabled with usb debugging on
4. read README.txt file
readme states:
1. power off device; RECOVERY : once off hold VOL+ and power for 5 s; pressing VOL- choose fastboot protocol pressing VOL+
2. run 'insecurebootflash.bat'
3. once rebooted go to fastboot protocol again
4. in Windows process manager kill adb and fastboot .exe
5. run 'cwmrecoveryflash.bat'
6. in developer's mode on device enable USB debugging and connect your Wikipad
10. run 'run.bat'
you're rooted
cortex69 via insecure boot made by myself
root method via motorchop (or something, can't remmeber exactly)

If anyone wants to use it or edit it go ahead. I have only built insecure boot.img
if you're not sure about you can try just to boot to boot.img
fastboot devices
fastboot boot boot.img
fastboot reboot
If anyone who has 4.1.1 installed and rooted Wikipad and is able to download but NOT INSTALL update firmware and pull it out, I am waiting for that someone. I will gladly take over the firmware and do my best to make it customizable and rooted. Might even take a look at kernel

My phone boot only on fastboot & recovery mode

Hi,
I have unfortunately erased my rom before install in my phone.
Result my phone can boot on “fastboot mode” (push down) and “recovery mode” (push up) but write “No OS installed”.
When I used PC for unlock my phone by USB, the PC can’t detect my phone and I am blocked.
My phone is over or what do you can do for save it ?
Thanks a lot.
If you can access fastboot your phone is fine. It seems like you just have a problem connecting it to your pc. Try another pc. When you get to fastboot install a custom recovery, and flash a new ROM from there

My phone bricked after Flash

Hi Everyone, sorry for my bad English if my question not clear enough:
- Phone model: Lamborghini 88 Tauri, snapdragon 801 MSM8974PRO-AB, 3/64 android 4.4.4
- After flash the ROM of LG G3 android 4.4.4 (I cooked but not well) ==> TWRP status sucessed, but No OS to reboot (only 16Mb), so i decided to restore (this steps i did so many times as backed up in TWRP). However when i reboot i shutdown immediately and totally bricked can not boot.
- I followed the guided to use Stock ROM of Oneplus X (same Qualcomm chip) to flash by Qfil in EDL mode, all success however it still can not boot to recovery (Only LED light flashing but not charging). So i decide to Flash another Stock ROM Xiaomi Mi 4 but now can not connect to EDL mode again.
- Facing issues now: Screen if off, could not access so i can not enable USB debugging for fastboot commands & unlock bootloader. Also ADB command can not use as it show no devices connected (Only can use Fastboot). Another issue: i can not go to EDL mode because whenever i connect the phone ==> LED light on and look likes charging mode (tried to keep power button or combine with volume +- but still show No Qualcomm Port... I used fastboot-edl tool, it shows:"done, entered EDL mode" but the driver still available on Device Manager & can use fastboot command, not really in EDL mode.
Really appreciated for You all support.

Be happy, you sucessfully entered Fastboot mode. Now direct Fastboot on PC per Windows CMD and/or PowerShell what action(s) to perform.
