[Q] How to unbrick my 4X - a question of life and death!

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 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
Click to expand...
Click to collapse
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 :[

[Q] LG L70 kinda bricked

Hello all..
I'm sorry if this is the wrong section, but I can't connect my problem to anything similar..
I've been removing system apps on my phone and, unfortunately I selected Lg Home in a group, and without noticing I deleted it.
I did restart it after it.. and the problems started.
I was able to select the custom Home by LG somehow, but I'm enable to go into settings (getting "Unfortunately, Settings has stopped.")
After that, I noticed that I cannot do really anything on the phone.. my PC no longer recognize my device, usb debugging is disabled.
In addition, I cannot get into fastboot (boot loop, when I'm holding the keys),
I cannot go into recovery too.
I could only get to the LG hard reset page, did reset the phone.. with no success at getting anything back.
I have terminal emulator and SuperSU on my phone (it's rooted).
Is there anything I can do with the terminal? Like send LG drivers to my PC, or restarting in fastboot/recovery?
I even tried to flash the original ROM with LG Flesh Tool.
With that program I cannot get phone information, and when I try to flash I get a message saying that Upgrade stopped due to an error.
It asked me to restart and bla bla.. still same
I did try it from download mode, but my phone did not got recognized on the PC again, so nothing there too.
Whenever I connect the device to the PC, windows is searching for drivers for MTP Usb Driver (and fails everytime). Note: I did have those installed before I messed up the phone.
I have ADB and I'm working with cordova, so I tried to install another andorid on my pc, and it got recognized right away (every driver was installed without doing anything, and I can shell it).
Any advice?
Thanks.

Sorry for spamming..
But, nothing really??

OP3T Bootloop - no way to flash new firmware?

Hello!
I am a happy owner of a OP3T 128GB version, but I've currently ran into an interesting issue . I am familiar with rooting android, fastboot, adb and stuff and I have limited experience (a begginer, but a quick learner ) with some other android phones. I hope I'm not creating a duplicit question - I am really sorry if I am, but I haven't found a solution to my problem even after hours spend behind the desk.
Long story short - accidentaly did an Advanced wiped in TWRP (3.1.1-0) and wiped my system (OS) and everything in the phone. I don't really care about the data, but checking the Sysem box in Advanced wipe menu has brought me into serious trouble it seems. Of course, I got a bootloop - my bad, right , nothing I can't fix I thought... But when I approached to try to flash a zip or .img of a system file/stock ROM respectively, I found literally no way to do so. My phone isn't recognized by my PC(s) (Windows and Mac) and I tried everything I could. The device isn't even a Qualcomm or sth. in the device manager - simply nothing, I can only get the device to charge sometimes when connected to the PC (seen in TWRP). I cannot connect an USB key to it via OTG either in TWRP to flash from there - TWRP just does not seem to know I even plugged a USB into the phone. I tried OP drivers, adb naked drivers, the phone and the PC just don't seem to be communicating at all.
The device can boot into fastboot, recovery (TWRP) and if proceeded TWRP prompts with "No OS installed" and I get a bootloop as expected. Is there any way I could try to flash the device with proper firmware? I do have the firmware and everything, I just can't seem to find a way how to flash it . I am a young student who just likes to play with tech stuff and devices and messed up and cannot help myself and I am really hopeless at this point . Any advice is greatly appriciated.
Thank you so much.

If you can flash/boot into TWRP, then probably nothing is lost. While in TWRP, if you connect your phone with PC, what happens? Do you hear the usual USB connection sound? If yes, what appears in the device manager?

Even if it doesn't appear in device manager, don't worry.
Boot into TWRP, go to storage, DISABLE MTP and enable it again. I know it sounds dumb, but just try it. It will be recognized as long as you have the proper drivers installed.
After that copy the zip of an OxygenOS based ROM like FreedomOS and flash it. Don't wipe anything. It will boot fine. I've done that a few times, never had a problem.

Thanks for the advice guys - no, no sound, nothing - as I said, I only get the charging (+) icon in twpr next to the battery percentage.
I did disable and enable MTP before - although not plugged in a pc during the process - will try if I have the chance.
One more thing that might ring a bell for someone - I tried the key combo for hard reset today(power + vol down) for a couple second and moments later I got a fuzzy (random colored pixels) screen and a red led. Weird, if you ask me.
P.S.: Today I tried to chat with OP a bit - 230 Eur for a new MB (64GB) and 255 Eur for my 128GB version - I just wanted to know, I'm still not admitting failure though. But as a student, these numbers from the support literally hurt me when reading...

1) try to update the twrp to the official 3.1.1.0. Then flash the latest modem firmware for your device and try to flash a custom rom like lineage os (a 7.x rom)

If you connect the phone to PC in TWRP and your phone is not recognized, chances are good that either your phone's USB or the cable (or the USB port on the computer) is not working. You can try to download the adb driver installer from here, just to check if your phone is listed by the installer: http://adbdriver.com/downloads/

Update - tried the MTP Enable/disable option in TWRP (in the Mount menu) while plugged into the PC, with no luck
IvanPrince - have you actually read the description of my problem? I have the 3.1.1-0 and even if not, how should I actually flash another version of twrp? The problem here is I cannot seem to find a WAY how to flash ANYTHING on the device.
I'll see about the adb drivers and update.
Thanks all,

Does the phone show up as anything on the PC when you boot to fastboot? I re-read but didn't see anything about it.

Nope - nothing. By now, I believe it is a hardware problem as the phone indeed got wet before my mistake with the advanced wipe. It appears to work just fine though, apart from the connectivity issue, so I believe the MB should be ok as everything else, including the screen is.
I just have one, perhaps a little courageous thing I'd like to ask from someone kind enough. Anyone with a Oneplus 3 or 3T who's not afraid to open the phone for a couplne minutes and has a multimeter alongside with a USB cable should be able to help me. :angel:
Could you, my awesome stranger, check where the 4 USB pins (on the side where you plug them into the PC) lead (make contact/'BEEP' on the multimeter) with the actual phone motherboard? It would REALLY help me in troubleshooting and perhaps saving 250 Eur. So far, I have this: (same color means contact) at that point. See picture.
BLACK - GND (all the heatsinks are connected to GROUND as well)
GREEN - DATA +
YELLOW - DATA -
RED - VCC
If anyone decides to open up their phone and help out a fellow xda guy, it will be greatly appriciated. :angel:

Hey Bro I was curious to know if you tried this method of recovering from a hard brick... When I first got my 3t something similar happened to me. I can't remember all the details of my hard brick but I thought I was f***ed. Please try this if you have not already.
https://forum.xda-developers.com/oneplus-3t/how-to/unbrick-unbrick-tutorial-oneplus-3t-t3515306

Might be a dumb question, but you did remember to mount the USB when you connected the otg right?

If the bootloader is unlocked, you can save it.
I would flash the stock recovery and the latest factory image (4.1.7)
Download them both from here:
http://downloads.oneplus.net/oneplus-3t/oneplus_3t_oxygenos_4.1.7/
After flashing the stock recovery using fastboot, boot to stock recovery and sideload through ADB the stock factory image.
Reboot and after checking that everything is working fine, feel free to relock the bootloader if you wish to stay 100% stock.
If the computer doesn't recognize it at all then it's a driver problem, not the phone... at least that's what I think.

try to use the program to fix my oneplus 3t it said download complete. try to restart

Alcatel Idol 4 6055K problem with firmware

Hello,
I have a somewhat aged Idol 4 lying here.
This no longer boots or it hangs in the boot loop.
So I tried to install an update via a stock rom from the network via the recovery menu and ADB sideload and always got the error status 7. (Alcatel_Idol_4_6055K_01001_01002_OTA)
Resetting the system didn't help here either.
Then I tried to install TWRP on the device.
But unfortunately both methods that I tried failed.
Once via Sahara & firehose-test and the second was Suger QCT via the download mode.
But both of them got the error message NPRG Error 5002.
I have installed suitable USB drivers.
So my question, does anyone have a tip for me on how I could get the device revived?
And Sorry for my bad english

Hello, I deleted my system from twr without realizing what I was doing, the result is that I stay on the Alcatel logo. My steps were, the installation of sugar, when it starts not to update the application. Choose the 6055 model, since the 6055P model that is mine does not appear in the drop-down. Before starting sugar, turn off the mobile completely and connect it off to the usb of the pc, check if when connecting it the pc does not detect it, use another cable (there are many cables that only serve to charge and not to read on the pc) Now start sugar, choose the model and click on the Udgrade tab. You will surely get several messages saying that the mobile has been modified and that you lose the guarantee, go ahead accepting the message, in a few minutes you will have it ready. Greetings.

Hello, thanks for the answer and the download.
I've tried the same way. I still downloaded your file and tried as you described.
Unfortunately I got the same error NPRG Error 5002 again.
Unfortunately I have no idea where the problem could be.

I found out that it could be a memory error.
As if a flash process had failed and there is no longer a correct series of partitions.
So I would need a complete original rom and would have to flash it via fastboot.
I could also try it via twrp, but I don't get this flashed.
And I don't have a complete original rom either.

Hello,
So I have now been able to flash the phone with another PC with Sugar QCT after it suddenly started up after the battery was completely empty and I charged it again.
But unfortunately the boot problem persists after turning off the phone again.
Even after replacing the battery with a new one.
Then I tried to flash TWRP via the Alcatel Flasher.
The flash process was successful but there was no TWRP on it after the reboot.
So the problem could still be somewhere else than just the firmware.

Hello, it may be that you are making the same mistake that I made when installing recoveri. When selecting the recovery, note that the twr is the one that weighs about 14 mb and the original one about 24 mb. I think that when you make a copy with the recovery program and then install the twr you select it wrong. In the program, do not make the copy of the recovery, skip that step and go directly to install and select the 14 mb file. You will see that this is the problem. Cheers

[NEED URGENT HELP] with my mi 8

Hello everybody how should i start to explain my problem……
my phone was by the police for 14 months and they tried to crack my password und recover data from it.
They couldn‘t and they send my phone to cellebrite and they couldn‘t do anything too.
Now after 14 months i got my phone back and i charged it first of all and then i powered it on (sry for my bad english).
I started the phone and all i can see is that my phone is stuck in recovery mode now,
when i try to reboot to system it will boot up to recovery mode again with a error message „This MIUI version can‘t be installed on this device“.
I tried to Connect with MiAssistant but when i choose „connect with MiAssistant“
and connect my phone with my PC, MiAssistant don‘t show any devices.
How can i Boot to ROM without loosing my data ? I need everything whats on the Phone especially the installed apps with saved login data.
I need my phone like it was before they took the phone from me. Is it possible ? Can somebody help my with my Problem ?
I think they opened my phone to do EDL because my backplate seems to be opened like you can see on the pictures i attached.
Before they got my Phone, my phone was i think rooted but i cannot remember any more but it had 100% installed TWRP which is gone now too,
and my bootloader is locked and i dont know if USB debugging is on or off now.
