[Q] Optimus 4X HD full brick

I tried to put the CM10 on my phone, after installing the zip in recovery mode, I rebooted the device and it never returned to start. Does not show a single light. Do not enter in any way with any combination. When I connect by usb the only thing that appears in device manager is "apx device." Already tried so many things and nothing worked.
anyone have any idea what's going on?
by the way, I tried a lot here in xda before opening a thread.

is your bl unlocked?

does it vibrate? does it turn on? can you control it through adb? can you enter sw mode?

No, no, no and no. the only sign of life when it is connected to the pc. Appears "apx" in device manager.

Yeah you are in apx mode, which is basically the boot section of the nvidia tegra chipset.
You should be able to boot normally by unplugging the phone, remove battery for a few seconds, reinsert and hold power button for about 10 seconds
Also try holding power and vol+ (hold them a while) you should be able to boot into normal recovery

I've try that but dont work.

In device manager the apx device is it properly installed or does it have the triangle?
When it first connected as apx device it probably asked you for drivers, i doubt you installed them.
I don't know if the apx drivers for the 04 are out already, check these terms in xda i know some people have been working on them.
Maybe you can find them here
If the device isn't bricked you are in a situation in which you should be able to flash stuff.
For some this method worked:
Try turn off phone
take battery out
hold vol- and put usb cable into phone
if s/w mode starts put battery in and flash kdz
Otherwise check this thread out
or this
I have to go out and can't follow you for a while, sorry

The only way for you to get connected in APX is without battery, connect to PC while pressing vol- & vol+.
Anyway... why you want to do that? APX mode doesn't work in JB.
Ok... I got it.
Did you tried to deactivate the APX device in device manager?
You can try to performe the bootloader unlock again (run adb and connect the phone while the program wait for device...)
http://www.4shared.com/rar/HFf4newq/LGO4X-UNLOCK-BOOTLOADER.html (instructions inside).
Or try to get in SW mode by trying untill it works... (connect to PC while pressed vol-).

Any update on the problem?

No, i think what happened was that all the firmware is erased and this naturally gave access to apx that should be hidden by the software. Probably there was some error when I wipe to put the CM10. I see no other explanation.

The phone is actually mine. Already sent it to warranty hoping they'll fix it.
Resuming, the phone went unexpectadly in APX mode and havent found a way of quitting that mode, couldn't boot S/W neither bootloader.
And btw the phone is carrier locked and to be honest I'm not sure if it might be part of the problem or not. Anyway in about two weeks the phone should be back and hopefully fixed. If not I'll check here for some more help guys, thanks for attetion so far

Problem after miflash

Hey guys, I need your help, I bricked my phone yesterday, and trying to solve it I used miflash, but now that the process finished my phone only vibrate and show a green light and then start a loop , and my pc wont recognizes my phone, somebody can help me please?
sorry for my bad english

Could you give more info? Which phone, what bricked the phone, bootloader locked/unlocked, what do you see in device manager on your PC?
Are you able to go into fastboot?
There's another user dealing with a bricked phone currently here, see if anything there helps you out. Link: https://forum.xda-developers.com/zuk-z2-pro/help/zuk-z2-booting-anymore-restore-t3539804

So in the last days I bricked my z2 pro by closing the bootloader with a custom installed, and to solve the problem I put it in EDL mode and I used the flash mi, but now when I press the power button it just vibrates and flashes a green Led, but it does not turn on, I already tried several combinations of buttons to get into fastboot and nothing, and when I plugged the usb into the pc it shows nothing

Hey! You may be on EDL mode.
To exit it you have to press power button and one of the volumes buttons, though I don't remember which one. Just have a look on Google and you will find something.
As for the certificate, I saw people having that problem if they replaced the front camera or the face id module. I don't if that's your case, but as you have root you may be able to recover face id functionality.
Let me know how it goes!

Then you are on EDL mode, as when you boot in that mode, the phone change how it shows up on the PC. You need to try to get out of there. If you can't, as you said you were having issues with the OS, maybe something is broken and the phone can't boot up.
When Android starts it has 2 bootloaders (the normal bootloader and the secondary one, which has EDL mode). If the standard bootloader fails, then it uses the second one which is EDL.
So here are some suggestions:
1. Try to hold the power key + volume up key for several seconds. If it doesn't work do the same with the volume down key
2. If that doesn't work there is another method, though it's riskier and might not work. Try to open the phone and disconnect the battery, leave it disconnected for some seconds, reconnect and try to boot the phone.
If none of those things worked for you, it means you will need to flash the firmware to your phone using EDL, as the bootloader is damaged.
Unfourtynaly there is not much info on using EDL on Pixel devices, though a lot of people use EDL to unlock Xiaomi's bootloader, so maybe have a look on those forums. On my profile, I tried to use the EDL mode to unlock a Pixel bootloader(mine is carrier-locked), though had no success, you will find a lot of helpful information to solve your problem, like the tools and files you will need and some overall idea of how EDL works.
Hope those help you and let me know if I can help you further

Follow this guide, replace carefully, the specific files that are for your model device, instead of using those that are for that model based guide, i.e. your firmware https://forum.xda-developers.com/t/...india-6s-using-spflash-tool-for-free.4222027/

Just keep it trying, change the port USB, power off your device, then try again, try a different firmware, flash one file by one. This error uses to appear.

Probably i had a similar problem.
Does your phone screen stays dark and the phone vibrates shortly each 20 sec? And you don't see any device when connect to PC over USB?
In my case when i held VOL+ and VOL- for a long time, the phone attached to PC shortly for programming.
I followed this manual
https://forum.xda-developers.com/t/x7-max-and-gt-neo-flash-ubrick-instructions.4337339/
and ONLY A15 firmware worked for me! But i had to uncheck boxes in SP FlashTools from:
opporeserve2
cdt_engineering
md1mg
After that flashing was successful.

Usually you have only ~10sec between auth bypass and phone disconnect... It is necessary to do fast: open the options in SP Flash Tool, select the COM port, then click 'Download'.

Your device is xiaomi right? Plug your phone to charger for couple of hours.Then, try pressing VOL UP, DOWN keys to get into recovery or fastboot mode while the charger is connected. You will be able to put your phone in fastboot mode i guess.
Flash the boot image and recovery image through ADB. Did you unlock the bootloader? Can you please tell me the model of your device?

Did you try some of the guides provided? It is not that hard to set up the drivers to can bypass the SLAA/DAA restriction, also you have other forum explaining how it works https://forum.xda-developers.com/t/mod-dev-mediatek-mtk-auth-bypass-sla-daa-utility.4232377/ there are various sites speaking about it, you have to keep it trying.
Can you enter to recovery, or fastboot mode? (this is done through stock recovery), I know you can't turn on the device, so you're bricked, but you have to try other modes, this will give you the certainty that device is not totally bricked, but only display is not showing a thing? When you try the various modes available, check on device manager from Windows, to see if the device is detected properly, open it in a part of your screen while you are trying.

Asus Rog Phone 3 Uber hard brick

Hi Guys,
I really need help with this one. I have tried almost everything.
Here is my problem.
I have an Rog phone 3 strix edition QUALCOMM based.
I repaired the screen because i dropped the phone.
Everything was fine working well. Me with my big head decided to do an factory reset to wipe everything clean from the phone and then the problem started.
The phone was restarting every time i plugged in a usb c cable. If i wanted to listen to some music on headset wont work because it will end in a bootloop.
Now the phone is stuck in CSC Fastboot mode and PC wont recognized it. The screen will turn on and send me to CSC fastboot but that's it. I can turn it back off.
Can i Revive the phone or is it food for the recycling bin?
Please Help.
Sincerely,
Ayolyas

With some effort you should be able to get back on track - unless it's hardware related to the display change you've done.
Can you do a reboot to bootloader from the boot menu? If you can confirm if you have fastboot access. If you do, RAW flash the device.
Worst case, you force the device into EDL mode and do a flash from there, but leave at as the last option.
If the relpaced display is causing harware issues, that's a bigger problem...

Hi Andrologic,
I cannot reboot to the bootloader. I am stuck in csc fastboot. I was trying to put it in edl mode i even bought an edl cable. But i have no idea how to use it or how to put the phone in edl.
I went back to the repair shop but the phone was working fine when it left the phone shop. The problem started when i decided to go for factory reset.

So, when you turn on the device, it falls into CSC FB and you can't navigate anywhere at all from there?
What happens if you try to do a RAW flash from CSC FB?
Flashing it in EDL mode may otherwise be the only option. Power off the device completely. Then hold Vol up+down pressed and connect to the USB side port. You should land with a completely black screen and on your pc see the device identified in 9008 mode - that's EDL. Since you have a flash cable, you can obviously use that too.
Remember you need Qualcom drivers installed to work in EDL mode. There is a guide with steps for EDL flashing somewhere here on the forum. All the steps are explained.

I cannot navigate anywhere from csc. If i try to reboot bootloader i will end in the same place.
I try to connect like you told me Vol up + down but i ended up at the same place. An raw flash from csc fb how do i do that?
And the steps for edl if you can help where to find those steps because my google history is full off items and still no luck finding the right one.

Yes, you have flash cable, so getting into EDL shouldn't be an issue any way.
This is a useful video on how to use your flash cable to force the device to EDL:
Just remember you need QCom drivers installed to flash in EDL mode, the normal drivers won't do it in EDL.
What is the device identified as on your PC when in CSC FB? Can you send any FB commands to the device at all? Does 'Fastboot Devices' return your device id? If so, try first to do a RAW flash from the Fastboot state you are stuck at. You don't really want to mess with EDL if you can avoid it. Download one of the RAW rom's from the links here on the forum. Version number doesn't matter as long as it matches with your device version, i.e. WW assuming you're on Global.
