My phone got stuck in Fastboot mode

My D855 got stuck in Fastboot mode, i try to get into TWRP, but also got stuck at teamwin screen. I went to Download mode, but then straight direct me back to Fastboot mode..... Now my phone couldn't switch back to adb mode, only stays at LG screen..... What can i do in fastboot mode? I try to do the command to restore the stock recovery, no working at all.....and all errors..... And my pc only can detect the phone when its in Fastboot mode, which is i can't flash stock rom or else..... Is there anything that i can do to get my phone back?

Which twrp are you using. I can't find for d855 only the d851 it has unlocked bootloader

Nah, now the phone only stays at LG screen or fastboot mode, so pc couldn't detect the phone at all....

No solution?

Check my guide in general section

Why did you install TWRP if you have a locked BL? Have you tried sending commands via fastboot to get into DL mode? Also have you tried to flash the stock ROM via fastboot using the fastboot flash img command?

Your phone is in secure lock! and flashes led?
Hold power and vol down when turning phone on, when LG logo appears stop pressing and press again, then it will say to hard reset, say yes!, then u go to fasboot, from there fasboot boot TWRP, and do what u want!, remember to see instructions! you have to backup ur recovery just in case...

Actually G3 only have one or few versions are BL unlocked, and they are not the international version that i got, so no hope..... Since i took it to warranty, what they have to do is to change the mainboard and that's it

The thing is they can't check it out coz they can't use the ordinary way to access into the phone and its files, so the only way is to change mainboard

Only the D851(T Mobile) has an unlocked BL. I would just be careful because they could always not cover it under warranty.

But there was no official service to the man who revived all.
Try to find out if he can help remotely.
Shipping to Ukraine for repair will be abnormally expensive.

I bought mine from Hong Kong, im in Sydney, so i took it to LG in Sydney to check. And they said they only can do is to change the mainborad, but since the phone is not bought in Australia, so i have to pay. That's why i send it back to Hong Kong for warranty.

Unbrick bricked by writing boot.img to wrong mmcblk

Hello community members,
TL;DR no adb, no fastboot, no flashmode, no QDloader (or similar) ... how to unbrick it?
I was trying to force Android to allow lower lcd backlight brightness levels by patching framework-res.apk and I had the edited zip file ready to flash. Then I realized that my Android 7 Ressurection remix ROM (thread) flashed Cyanogenmod recovery, which I don't like. So I decided to reflash TWRP 3.0.2 (link) ( edit: using "fastboot flash boot twrp.img", which was almost fatal mistake) and it has gone almost well. The phone started to boot into recovery mode everytime (and took a long time doing so). So I googled a bit and found this thread which lead me to this thread. I was looking forward to seeing my display brightness at lower than default values, so I probably skipped some security checks and texts with red color, so I flashed the zip with the boot.img replaced. After flashing I chose reboot and nothing happened since.
The problem is I flashed something that was not for my device (extracted boot.img to wrong mmcblk). The command that bricked my phone is (from META-INF/com/google/android/updater-script):
Code:
package_extract_file("boot.img", "/dev/block/mmcblk0p6");
After that it doesn't boot, doesn't light up LED (even when charging), doesn't get detected by PC in any state.
So I have no adb, no fastboot and no flashmode and not even a QDloader or similar mode.
Is there a way to unbrick it?
EDIT: How to unbrick it using JTAG interface? If I find somebody that has the required equipment, what data do I need to give them?

Hey there! Did you manage to solve the issue, because I just got into the same situation after the zip didn't save the corrected partitions but the initial ones... So i ended up without any signs of life in my phone

Nope, I found no solution ... even some kind of Qualcomm flashing mode via COM (serial port over USB) does not show up nowhere. I gave up and bought a used S5 mini, which is full of features I appreciate.
I'm gonna keep this Xperia M for some time if some solution comes up.

can you still access fastboot mode? anyway you need to know first what is exactly partition that you overwrite with boot.img :/

No, as I said. The partition that got overwritten was /dev/block/mmcblk0p6. It was overwritten by boot.img from LG OPTIMUS 3D that I link to in the main post.

Question Soft Bricked T-Mobile OnePlus 9 Pro

So, I soft bricked my TMO OP9P. I can still access Fastboot but can't access anything else. After leaving fastboot, when the phone is rebooting, I just get a black screen.
On plugging it in, It shows up in ADB as unauthorized, and with no prompts to authorize, I can't get any further.
Any ideas?

I did that to an HTC U11 once - Never got it recovered, had to toss it...
Never dared relock a bootloader since...

I had the same thing happen to me.
The only thing that worked for me is to boot recovery and wipe system. Good luck

i have the same problem let me know if you figure out a way around this !

For all of you having this issue, simply use the msm for your respective device by unplugging your phone, select power off, enter edl mode with cable plugged in and run the tool. I know another solution, but please PM me if this one doesn't work.

I had this issue as well, but you better not have messed with the sensitive partitions without a backup, otherwise there's no way to repair it.

Did you try booting your phone into EDL mode? Hold down both the volume buttons, and while holding them down, plug in the USB cable (Connect with the PC). If you're on Windows, check the device manager in the control panel, and check if the PC recognized the phone (you might need to install the drivers too).

Yes, it's for the Pro, but the procedure is the same. A good thing is that EDL works. Now just grab the MSM Tool for your model and flash it.

im sorry i just realized i jumped in the middle of a different thread. This happened while trying to flash tmobile oneplus 9 pro to global firmware and after trying to enter recovery mode. Im guessing it happened because the files are for one plus 9, so im looking for the files for a 9 pro conversion but only am finding msm tool downloads for conversion instead of flashbin files.

i have the le 2127 from tmobile because i didnt know any better. i dont want to root or do anything crazy. I just want to be able to flash to global or eu firmware so i can upgrade as oneplus releases the updates and not be a year behind on tmobiles schedule. I have the sim and bootloader unlocked successfully. I started to flash to the one plus 9 firmware because i somehow missed that it did not say pro. So now my phone in unresponsive except for QDL 9008 mode. MSM tool recognizes it and begins to update it but then gets a param preload "device not image match" message in red and stops. So once i figure out how to get past that and get this set to factory, i want to properly flash it to global or eu, whichever is available, and upgrade it to the latest version.

Are you getting the mismatch on the global/eu MSM or are you trying to flash back to stock T-Mobile? You're getting a mismatch because you're most likely using the wrong version of a firmware (msm).

Question Hard-Bricked Poco F3 (shocker). Won't boot into EDL.

Hello peeps.
My Poco F3 got hard bricked after update froze (was doing clean install of stable EU rom). Phone won't boot into any mode, and won't appear on pc. I've tried sorting the Test Pins 50 different ways and it still doesn't get picked up by the pc. Qualcomm Drivers are installed. Device is connected with working data transfer USB cable. It definitely is getting charge cause Battery and CPU are hotter than the rest of the phone. I'm at complete loss, I have no idea what I'm doing wrong or if I screwed up my phone that bad that EDL also doesn't work. Thanks for anyhelp!

1. Disconnect the battery
2. Make USB-Cable ready for Insertion
3. While shorting the 2 Test-pins, connect the USB-Cable
This is how I had to do it. ^^ This can be difficult and may require multiple trials, but this should work!
Windows should make the "Hardware connected"-Sound directly after connecting the USB-Cable, and show "Qualcomm 9008" in Device Manager.
If not, you need to repeat it: disconnect USB, short the 2 Test-pins and connect USB again. All while leaving battery unplugged.
Note: EDL Mode can't be bricked. This read-only Mode resides inside the Qualcomm SOC. There would have to be physical (hardware) damage for this to not function.
If you need more assistance or so, I can give you my Discord. Though you already seem quite far. Good luck dud.

I am assuming the phone screen does not light up at all, no fastboot or recovery mode.
This would mean the phone's hard bricked. It will require EDL flashing which can be done by someone with an authorised Xiaomi account.

Yes. Just to be safe I would flash the rom with "clean all" instead of "clean all and lock" if I were you. Then after booting up the phone you can later lock the bootloader safely using "fastboot oem lock" in adb.

In case of "clean all and lock" if something goes wrong during flashing, the bootloader will be locked and you will not be able to fix the phone. So it is safer to flash the rom first without locking the bootloader and then lock it after booting up.
