My phone's bootloader is locked and it's stuck in a bootloop.
I'm currently trying the Two Point method to re-flash my phone(the only options to unbrick a locked phone).
But I'm having some issues with that too. The phone still keeps auto booting(continuously) when I plug the USB to PC even after I disconnect the battery connector from the phone and won't enter EDL mode when I touch the two points. And I don't see the Qualcomm 9008 or any of the ports from Device Manager.
Any suggestions?
Did you try unlocking your phone via official method(if again)? Then flashing MIUI via Xiaomi Flash tool?(it also works in edl mode.)
Try unlocking bootloader via official method via mi flash tools and then flash ROM.
Or try this method on your risk, read carefully before proceeding.

I have half-bricked P880. Bought just a week ago.
My ROM is stock V10C. I’m trying to get rid of that crap ROM, but so far without success.
I have rooted the phone but flashify is the only app saing that the phone is not rooted. Every other app which requires root is normally working. I can’t unlock the bootloader because phone can’t be recognized by any computer, using different Windows, USB cables etc. It just shows charging but PC doesn’t see any connected device. Nor the phone shows any connection option when I connect it to PC by USB.
I’ve tried to install TWRP (without success) and CWM (successfully) but the phone can’t be load into bootloader. Just an LG logo will appear and this error message:
[LGE_SECURITY ERROR] boot image signature
Critical failure: Unable to start kernel
Unrecoverable bootloader error (0x00000002)
I think it’s still locked.
This method hasn’t help either…
http://forum.xda-developers.com/showthread.php?t=2251407
What’s more, the error message appears almost every time I try to turn on the phone. Sometimes it takes 10 attempts until the phone will finally boot into Android.
Yes I’ve tried basic things like playing with USB debug mode, LG PC suite option/USB tethering… please don’t respond to my question by that kind of suggestions, I’m no rookie in flashing roms and Android problems.
Only hope for me is to flash kdz file via PC (when the phone is off and battery out). BUT I’m unable to do that, due to problem that the phone is again NOT RECOGNIZED by PC. Of course I've tried every kind of LG driver but the problem is in the phone, because the PC won’t even notify by sound that a phone has been connected to it. So I need to change the corrupted bootloader… somehow.
I’ve already searched everything to this issue on XDA and elsewhere - without any solution. So I’m 95% the phone is half-bricked without any chance to flash new ROM.
If none of those things that you said doesnt work, as last resort you should try this

Thank you for a quick reply! However the autor of the method says:
i mean when you get stucked with S/W screen, and you can't flash the device in any way
Click to expand...
Click to collapse
In my case I can't say that I'm stuck with S/W screen. Because I don't even get in there. Any PC in my home (XP/Windows 7) don't even recognize that a mobile has been connected to it. So there is no S/W screen. The only way I can get in S/W screen is to keep the battery in, but it doesn't solve anything. Because the phone remains unrecognized to PC. Therefore I'm unable to flash anything. A simple explanation in here arose: the USB port in my phone is faulty. BUT, how that can be, when the USB charging works fine and even S/W screen appears while the battery is in?
Either way I'll keep your suggestion as the final solution(since I'm very skeptical of it and also dont have screwdriver small enought to take out those tine srews) if there will be no other responce to my problem.
I'm not very experienced in things like this, but when I was flashing kdz to my phone, my computer wasn't able to recognize the phone with battery out, so I did whole process with battery in (and it worked)
anyway if you want to unlock the bootloader you have to update to official JB (just flash JB kdz and then wipe data in LG recovery to prevent bootloop)
so first you have to connect somehow your phone in sw mode to computer
then flash JB kdz and wipe data in LG recovery (it should be back even if you've flashed twrp)
and finally root JB and unlock bootloader (for example this way I found by two clicks here at xda, just browse Optimus 4x general category: http://forum.xda-developers.com/showthread.php?t=2251407 )
I hope I helped you a bit
I agree with you SuperLamic. Especially with this:
so first you have to connect somehow your phone in sw mode to computer

My only hope is to flash kdz file using fastboot mode. However after days of searching on XDA, installing all kinds of drivers, trying different methods etc., I'm still unable to connect my phone to PC.
Any PC I tryied so far haven't even made a sound while pluging my LG to it. Nor it's vissible in the list of connected USB devices.
So now I'm sure that a USB port on my phone is faulty There is no other possible explanation. But thank you all for your suggestions anyway.
P.S.
There is maybe a tiny chance for workaround by unlocking the bootloader without PC. But this method doesn't work. http://forum.xda-developers.com/showthread.php?t=2251407 With unlocked bootloader I woud be able to solve the problem without PC. Right now I can't install TWRP nor CWM because they require bootloader to be unlocked. CWM in ROM Manager always says that installation was successful but actualy, it wasn't. Since there is always this error when I try to load recowery mod...
[LGE_SECURITY ERROR] boot image signature
Critical failure: Unable to start kernel
Unrecoverable bootloader error (0x00000002)
EDIT:
So I find out that only JB ROMs can be unlocked. It's not possible with my stock ICS. So there is really only one solution: repair my USB port on LG to flash kdz. But I'm afraid that these days a repair will cost more than the phone itself :[
i was trying to connect my phone with usb cable but my pc not recognize any connection while the power charging working normally
i tried to check through fastboot but still the same also i tested 2 cables and 2 PCs still the same

Likely you have too much power coming from your usb ports, use a usb hub such as this: https://www.amazon.com/BYEASY-Porta...jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ==
Now try Mi Flash again, make sure that the lock bootloader (which is checked by default) is unchecked.
Now it should work, be sure that you are using a fastboot rom and not a recovery rom. ( a recovery rom will not work)
Make sure that it is a fast boot for your device : If you have a global device here is a link with quite a few fastboot roms :https://c.mi.com/thread-1899815-1-0.html
If you still have trouble let me know, and tell me specifically how you arrived at your brick, I helped someone with this exact issue a couple of weeks ago, and I was going to link you to that thread. But i can't find it at the moment.
I get the same error " cannot receive hello packet" with hub USB.
MY xioami mi 8 is global version, i unlock the bootloader and make a downgrade with twrp to a older version of stable rom, and when the phone start ,its all ok and login my mi account, and the phone goes down and never more boot. Always in the pc i get qualcom port (edl mode) . Sorry for my bad english.:crying:
I think i need account with EDL authorization to flash any rom. And i can't found anyone to save me..
Try https://forum.xda-developers.com/mi-8/how-to/unbrick-mi8-edl-authorized-account-t3896677
Thank you .. i try this metod but no success

Maybe try this site : MOD EDIT: link removed
I dont have his name but one of the techs from this site is a frequent XDA user and supposedly legit.
In the end there is a risk of losing $12. Seems to be worth $12 to me.
I send message to this brother , and it's 40 dollars .. i'm thinking about
thanks for reply
I installed android 12 beta on my Mi 11 ultra. Did not like it and wanted to install global. Installed TWRP, wiped data and instead of rebooting in twrp, I tried to enter fastboot mode via adb. The phone screen turned black. Now it is not showing in ADB, not detected by Mi flash tool, not enetering fastboot mode and not entering recovery. When I connect it to computer, there is this connecting sound but soon it is followed by disconnecting sound. Not even getting the charging screen. In the device manager on Windows, there is this Qualcum HS-USB QDLoader 9008 (COM9) when the phone is connected via USB cable to PC.
Anyway to restore any firmware on it? It is a CN version, star, has bootloadder unlocked.
EDL time? Or even worse? Is it paperweight now?
EDL time I think.

Believe me, this is reassuring. I'm happy to settle on EDL instead of paperweight... For EDL does the phone need to be opened, back cover removed and then that magic short circuit or is there a way to get it done without opening the phone?

Don't worry. When mine was EDL flashed the guy asked me to download a specific miflash version that he had the link for and the ROM of choice to be flashed. I connected the phone to the PC, he connected, asked me to put it in to EDL mode ( he will explain if your not sure) and done his stuff using TeamViewer with control of my desktop. Once finished, just rebooted when asked, all done.
need mi auth to flash
How do you put the phone in EDL mode?
can you get your phone on fastboot?

Hold both vol up and down while powering up or adb, adb reboot edl or fastboot, fastboot oem edl . You will see edl drivers load on your PC.
Thank you guys for your replies. I got it fixed and now it is rocking again. If anybody faces the same issue, please see details below.
Diagnosis: EDL mode
Signs and problems: Completely dead phone. Black screen. None of the buttons or their combinations work. Volume down plus power, volume up plus power, Both volume buttons, All three buttons. None of these worked in this EDL mode. In fact, the only sign that this phone was "alive" was the Qualcomm driver showing in the device manager when the phone was connected to a PC. There was this yellow sign even on the Qualcomm driver and the official Xiaomi flash tool failed to detect the phone due to the Qualcomm driver malfunction. Got the Qualcomm driver working (the yellow sign on the driver name icon in device manager) by disabling windows driver signature check. After this the phone was detected by the official Xiaomi flash tool. When I tried to flash the official and stock CN ROM, it did not allow me and gave the error "you are not authorized to download". Took the phone to Xiaomi service, they refused as the phone was of another region. They did not know any unofficial paid solution. Took it to local technicians. They tried but failed (ultimate multi-tool, some other tool they called as "aqua" did not work.
Treatment: Searched online and found a YouTube channel (
). Paid USD 35 and got it flashed via TeamViewer. I just sat anxiously (praying that he must not be a scammer...). He did some magic and successfully flashed the phone with the original CN ROM with the boot loader unlocked. I then was able to install the global version via fastboot as usual.
Thanks again for the free support I got here. Obliged and stay blessed

I tried this method today and it wasn't successful. It appeared he flashed it with his auth code, but it still doesn't power on. I'm so bummed because DHL won't touch the phone for less than $151 (risk of it being sent back) because seller wants me to lie and say it's a gamepad when DHL has precautions on phones being sent back, etc. requiring importer certificates.
My phone was acting strange on 3rd day: wasn't detecting charging USB cable overnight, would only charge wirelessly. I manually rebooted a bunch of times, then it detected the USB charging and would charge. About that time I updated to Miui 13 OTA update (Chinese /EN Rom) and noticed it was rebooting randomly in my pocket asking for PIN (not getting notifications) . Again got no USB charging through cable.
I was doing a bunch of vol up/down and Power and rebooted into safe mood. Rebooted again after things were 'ok' and little while later, the phone was OFF and never came back on again.
Did I put it into EDL and brick it this way? I Never flashed anything through USB until I tried the 35eur paid service dude.
Happy to see that is being fixed.
Wish it had fixed mine. Unfortunately, it didn't . Was refunded
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.

Hi,
Nope. I can get into EDL mode so i think it is hardware related. You can say it is fresh for the garbage.
