Bricked my lg optimus 2x

Hello, i bricked my lg optimus 2x by somehow, and i've read some on the forums and it keeps popping up that NVflash is the way to go. But the problem is nothing happens when i do it No reboot etc... It do react and say: S/W upgrade...
Also when i try to boot phone nothing happens, it is all black and no reponse... So what should i do ? I got no NAndroid backup etc

I haven't tried nvFlash, but Smartflash sure worked for me. (Verified it 10 hours ago as I just soft-bricked my O2X as well. )
You may follow instructions here.

can't find COM-port

So the problem is when i try to do that it doesn't find any COM-port :/

Try to install the LG drivers again and hopefully that helps finding COM-port

All of u is wrong. You have to use the method when you're holding vol up and vol down together. If u wait 'til I come home I can give you a link how its done.

The vol up + down method is used for NVflashing.
I used Smartflash so I didn't need to do that.
@random: Aside for checking for LG USB drivers, make sure that you have the battery pulled out, and you are plugging the phone to the PC with the volume down pressed.

smartflash
but it doesnt react to the volume down : P since what i've understand is that it should pop up a the LG bootup thingy
And it doesnt.... The only thing the phone reacts to is when i try to NVflash... but the nvflash seems to fail all the time by some reason :S in the middle of everything

take out your battery, plugin usb + hold volume down.
then smartflash all the way !

Wonder
i wonder how i smartflash then....
/watch?v=uCHRwKGTZTk] i followed that one, but he's phone react with a LG logo when he puts cable in and press vol down... Mine doesn't : (

Try using the USB ports at the back of your CPU (those that are from the MoBo itself). Are you using WinXP by the way?

Tried...
Yes, i have tried the other usb ports at the back and no im not on xp... Im on Vista
64bit.... It feels like i've tried everything that is possible.... So i wonder if there is any hope at all... Or could i turn it back and hopefully get it fixed ? Or will they be able to see what happend etc...

Thing is, if you have tried everything on your end, I guess there's no other thing to do but return it to the shop. I hope you have warranty.

Since you got to the S/W upgrade screen on NVflash, your phone can't be totally dead. Try another PC or redownload the flash file, it could be corrupted.

Dont worry, you probably DIDNT brick it
Search for smartflash and NVflash, smartflash should probably do the trick in this case, but in a few cases u need to use NVflash.
But try smartflash first.

Why flashing is so risky ?

Hello
I'm new android and samsung user for about a year now ! I'm just wondering why this flash procedure contains risk while it should not !
I've bought my phone with 400€ and i'm scared like **** to brick it, a normal thing isnt ?
Well what i want to say is, arnt these companies able to create an unbrickable phone in which i can install any android version like in my pc without risking the brick since i'm not touching the hardware part ?
Why these powerfull little things in specs are weak concerning the updating part ?
For me, its illogic to get a 400€ useless phone just after touching to its software part !!!!!
Do you think that its right ?

I believe phones like the SGS are really sturdy/robust and cannot be easily bricked.However if the situation is like a person taking the wheels of an automobile for the first time without any preparation or guidance and driving through a crowded street and thereby generating a huge risk,that is another matter then!
Invest some time reading through the various initiation guides in these forums some of which 'spoonfeed',and you are good to flash as often as you wish without the risk of causing any hopeless bricks etc.
Happy flashing ahead,but after understanding what it takes!

Flashing is risky only if you flash bootloaders. Otherwise it's safe (well it's good to keep USB jig near just in case) as you can always just reflash if something goes wrong. But I think you'll find more info from flashing tutorials.
Sent from my CM'd SGS

It's hard to brick the SGS. You just hear more about bricks, because no one goes around posting "OMG GUYS SUCCESSFULLY FLASHED!!"
The only real risk is if you flash over the bootloaders. The bootloaders are the software that control how the phone gets flashed, so if these are corrupted obviously you can't really flash it anymore. Problems arise if a) you flash incompatible bootloaders (like from another model), b) the flashing procedure screws up (your computer crashes in the middle of flashing).
It's actually pretty unlikely.

Flashing is not so risky process if you know exactly what you do!
Very often the device behind the keyboard screws up the phone.
People need to read and also getting some basic knowledge how the flashing process works would not hurt them at all. That's the key to a successful flashing

Well thanks guys for the answers ! It was recomforting ;-)
But again for me, even the bootloader shouldnt fear the damage !! Well its a point of view no matter whats the thing between the keyboard does
At least Apple knows how to push their customer to update their iPhones ! I had one and i never feared the updating procedures !
Well concerning the odin software does it write somewhere that the bootloader flashing went perfectly ??
Thanks guys ! And is there any super android phone to buy and which its updating still not risky ?
Sent from my GT-I9000 using Tapatalk

flashing aint risky, only moment that it could fail is the part when its flashing bootloader and that takes like second of the whole flashing process (or if youve putted absolutley wrong model firmware to flash)
from anything else you should just simply take out battery, put it back on and 3 button to download mode =)
and now with unbrickable mod its even more safe =)

Well... this thing with ODIN is not an official way to update firmware. It is a way to flash ROMs other than what your phone was supposed to receive. The official way is using Samsung KIES and only Samsung KIES. That is fault-free. If anything wrong happens you have emergency firmware update or smth. Don't compare official update with ODIN.

Actually I see more problems caused by Kies in these forums then I do Odin/Heimdall errors. Beyond that, because Kies is kept closed and limited by Samsung often times the user will have no idea why the Kies update failed, or how to resolve the problem. 99 percent of all Odin/Heimdall problems are due to user error or intensely bad luck while the bootloaders are being flashed and there is always plenty of support online for any error. I take Odin over Kies any day.
As for saying that the bootloader should be unbrickable, I know some people have recently been posting hardware mods that create unbrickable Galaxy devices. However, for most of us who are not adept with soldering irons and transistors, the bootloader is no different then the Bios on a PC. If something corrupts the Bios, all you can do is send it to the shop or replace the Bios chip yourself...just as all you can do with a corrupt Bootloader is use a Jig or sent it in for service.

Really??? So, please take your "unbrickable" PC, and unplug it in the middle of BIOS update (in case of laptop:unplug AND remove battery), and you'll see the results.

basicly you can not compare those two situations
Sent from my GT-I9000

Well, i'm talking guys based on information i learned from the unbrickable mod, these guys have created an unbrickable SGS, do you think Samsung or other companies aren't able to do that officially ? Yes sure they can, but they don't want to, aand i don't know why !!
And for the BIOS thing, i'm partially agree that it's also a dangerous procedure, BUT the difference is that no matter what OS you want to install, you aren't obliged to update the BIOS first, and again, for my 2 Years laptop, i remember well that i've installed Vista and 7 quitly without touching the BIOS
Well, this post wasn't a question at first but kind of "debate" bcause i wanted just to know how people are reacting in front of that situation !
Thank you all

So, who forces you to touch the SGS bootloader?
Same time, Win Vista and Seven are OFFICIALLY released systems.
To compare the situation fully, you should assume that:
- you have PC bought directly from Microsoft, branded by them;
- you want to install "homemade" Win 7 and 3/4;
- you are claiming that you are in problems.
By the way: BIOS and Win Vista or 7 are old systems already. Try to read what is planned and developed now with Win 8 and UEFI: Windows 8 Branded PCs Could Prevent Other Operating Systems From Being Installed, and then compare it with SGS.
Simply, Samsung develops the device with THEIR OS on board, and is not obliged in any way to support homebrew systems, possibly because of likely claims of home grown hackers, who would brick their stuff and then claim it as warranty issue. Flashing different OS'es is possible thanks to effort of the people who are not related with Samsung at all. To use an example going further, look here on the HTC HD2 thread. Device was originally supplied with Win Mobile 6.5, but Dev's managed to port Win Phone 7, Android, Ubuntu and MeeGo to this phone.
Do you think that this is supported by HTC, or the persons who flashed Android and bricked phone would claim that this is HTC's fault? Same is with the SGS: flash not even the stock, but official releases via KIES only, and if something will went wrong, then blame Samsung.
So, there is no situation. Just group of people, who have or not the knowledge what they are doing, while flashing.

dude.. its not about samsung and android problems.. when you're trying to update your phone OS, its risky on every phone. unless you know how to do it right. I just read that if your phone brick, you can bring it to life using USB Jig. I never try it tough, cause my phone is never brick.

[Q] Bricked LG P990?

I've bought a LG P990 today, the seller told me he had put the cyanogenmod on it but it wasn't very stable, en he couldn't get the stock back on it, so he sold it to me for a fair price.
I thought i 'll put it back to stock en i'll have a great phone!!
so i tried to flash it, but the phone wont even start, when i push the volume up and down buttons the computer recogniced it, but i can't get the apx driver installed (not on win 7 + win XP) now i'm stuck........
can some one give me a hand with this? is there a way to fix this or am i screwed sorry for the bad english. please help!

search for nvflash, if nothing else works this will.
Sent from my Optimus 2X using XDA App

i've already doen that, but then I'll need to install the APX driver, and that is the part where i am getting stuck. any suggestions?

anyone please!!

thats the driver on the pc? if so, what exactly is the problem?
Sent from my Optimus 2X using XDA App

I put the volume buttons down en connect the usb cable - the message 'usb device isn't recognize' - then i go to devicemanager - there is a "!" bij unkown USB device - left mouse click and point to where i stored the driver - but then i get the message" best driver already installed.
this is where i'am now - is there another way to recover the phone maybe with program on sd card or something?
the phone itself doesn't do a thing - screen black - no flashing lights, no nothing
am i doing something wrong? or is it really bricked?

i think you need a different driver for your device... here you can find the driver that i use http://forum.xda-developers.com/showthread.php?t=953182
and you might also need the NVFlash drivers that is found here http://android.modaco.com/topic/335...k-rom-release-v10b-dated-1300166062-15032011/

tnx for the reply, but i have already have these drivers..(the lg driver that i've installed i newer though, does that makes a diffrent?)

I also talked to the guy i've got the fone from; he said that he accedently must have whipped te phone memory, is this irreversible?

and i've tried on a other desktop computer with win xp proffesional! (usb on the back) can it be that there is no apx driver on the phone? is there another way to connect and flash?

If he had cyanogen on it have you check if it has flash recovery?
Sent from my Optimus 2X using xda premium

i can't check it, because the phone won"t start - screen stays black.

OK u will have to check where the phone is corrupted. When you switch it on does the LG boot screen start?

I think your phone is bricked. I had almost the same problem with motorola milestone. I bought phone with software failure. Seller was saying that he tried to update phone and it hanged so he sells it. I thought i will flash it and have a great phone. But I tried all of flashing, recovering methods and nothing... I took phone to phone service and they said that phone's motherboard is broken... So I sold it for parts and now I have LG optimus 2x. thats my story It hink you should talk with seller for more details. Also you can try to contact lg customer service. Maybe they can help you

I think that u should try on fresh win7 instalation.Put O2x in DL-mode and connect with computer.

You need to get the Nvidia driver for APX

Best thing to do I think is to try flashing recovery. Yu can Google on flashing recovery it's pretty simple. Yu will be halfway there once yu can get your phone in recovery mode.

My phone is HARD bricked!

I bricked my old Galaxy Mini with ROM Manager :crying: by flashing CWM for the wrong phone. I think it was some Huawei model. Nothing is working! Is there a way to unbrick it? :fingers-crossed:
PS: It's not nessecsary, I will buy a new phone.

1. search before posting
2. search before doing ANYTHING with phone
3. you can try with usb jig/j-tag, there's instruction on how to make one floating around here somewhere

Most important rule always read about the stuf your doing

lol sad everyone is doing the same mistake. If your phone is under warranty take it to samsung service center and tell them u set the alarm in the night and in the morning it never turned on. They will change the motherboard free of cost. If it is not under warranty. Buy a better phone instead of paying $100 for a motherboard.
PS: Theres no way to bring it back from that ROM manager brick.

Should really contact devs of rom manager to make it unavailable to SGM... More and more pppl are bricking their phones because of this.
For your case, try a USB Jig. Details and guides can be found in the link in my signature.

Lol, I bricked my phone too with ROM Manager. I selected a recovery for Geeksphone just to see if ROM manager has a protection for flashing wrong recoveries. And no, it doesn't have. I returned my phone to Samsung service and they replaced the motherboard. Now I continue to test lots of ROMs and my IMEI was bricked too. It's 000...

the app have the protection
wrong things is done by us by selecting wrong device model

Yeah its same for me ,i have bricked with rom manager ,after that i m going to samsung service center , they make my phone comeback but number IMEI is gone

it need some technical assistance from a service center and be JTAG.
too bad i think it doesnt have warranty tho.

a only way is assistance

i bricked mine too not from rom manager but from flashing roms. i brought a jig but it gnner take 2 weeks to get to me

By the way, I bought a new phone, and does anyone know how rom manager bricks the Galaxy Mini?

I think because it's installing wrong recovery image. Simply after recovery installed, ROM Manager will reboot your phone to recovery mode. Since the recovery image was wrong and unusable (since ramdisk & configs are different) the phone wasn't able to boot and ACTUALLY stuck on recovery mode.

But what does that have to do with the boot up sequence? Sorry, I'm an htc guy...

simply put, its like a one way door..once u enter into the room u cant go out..
same way the due to bad recovery and wrong mount partitions loading, once u boot into recovery using rom manager, u cant boot out..thus it will result in a hard brick..

I get it! It's all much easier with HTC phones... You can get inside a boot menu where you can flash roms and kernels and recoveries using the pc. In the boot menu, you can go to recovery. If you screw something up, flash a bad rom, kernel or recovery, you can always flag the right thing using the boot menu.

Did you post your issue in the official LG UP thread or in the back to stock marshmallow kdz thread where the file that you need to get this back to stock using LG Up is listed. If you would have searched in the kdz back to stock thread you would have seen that another user helped me with the exact same issue ss you. Was ready to turn my phone in for warranty before finding my answer there. Your phone is still able to boot into recovery manually but you have to do it a few times then you install a rom that's saved on your sd card and your phone will boot up. Hopefully you still have your G4 and can try this method.

Really I'm thinking not explain to me how my lg g4 phone can boot into recovery manually when i relocked the boot loader through adb.
All I have is down load mode No regular O.s boot no fast boot mode
Its all secure boot error 1003
I download the kdz 20i from auto primes code fire link that's the only kdz for 20i around .
The issue is lg up tool sees my device as Unknown model because I was on a ROM when this happened apparently there's no fix unless you can boot into the O.s and edit the ROM

This is impossible lg bridge is not a semi brick or full brick fix tool its a upgrade tool from what I see
lts for a device that's in a bootable operating state allowing firmware upgrade .
It can only read in a device in mtp mode If you only have download mode that doesn't help at all Withp lg bridge The unknown device model issue is only seen with the Other tool Caller Lg up.

Not being able to connect suggests driver problems. Reload them and try again.

No that's not true I guarantee you wasn't
Relocked boot loader u couldn't have been
I am for sure about this and lg bridge sees my device when I choose update recovery error it tells me there are No update errors that can be recovered
So how does that prove it fixed yours when we was in the same scenario?

I made a mistake when upgrading my phone from LP to MM and accidentally left my Bootloader locked when trying to upgrade, nearly bricking my phone. I was receiving a 1003 error every time I tried to boot. I posted this in a different thread last month for someone else who had the same problem.
I had this exact same issue when upgrading my phone. Didn't do it correctly and it took me about 3 hours before I got my phone working again. It was about a week ago on another computer, but I'll try to recall what I did when it finally clicked in my mind.
Download H81120i_00_0201.kdz flashable zip from here (1.6GB Feb-04-16):
http://downloads.codefi.re/autoprime.../H811/H81120i/
Download LGUP and install it. I used the DropBox link in this thread:
http://forum.xda-developers.com/g4/h...mm-lp-t3249803
Remember to install the LGUP_8994_DLL file BEFORE LGUP_Install
Download and install LG Bridge (for the USB drivers) here:
http://www.lg.com/uk/support/pc-suite
Select the LG 815 model, the drivers will work. I only used the LG Bridge to install the USB drivers. Nothing else.
OK, now here's where your phone comes in.
Step 1: Turn off your phone (pull the battery if you must, but put it back in).
Step 2: Hold the VOLUME UP button and plug the USB cable into your PC. This puts your phone into DOWNLOAD MODE.
Step 3: On your PC, open up LGUP. The program shoud recognize the phone as H811 in COM3 or COM4. Highlight it and click the SELECT button.
Step 4: Under the "Process" row, select UPGRADE
Step 5: Click the blank space under File Path, it will pop up a [...] [X] at the end. Click the [...].
Step 6: Select the H81120i_00_0201.kdz and click on Start. The program will push the STOCK H811 MM ROM to your phone. This will bring your phone out of Brick mode, but you will have to go through the entire rooting process again.

Once again I was on a ROM when in did all this if it wasn't for that fact Lg Up would see my device model as h11 not unknown
So tell me how to get past the Unknown device model issue due to bring on a Custom Rom when this happened

The issue lies in step 3
The phone doesn't recognize as h811 it is as unknown model
If you know a way around that I'd love to know because every day I Go to snap the phone in half and recycle it as trash I stop my self thinking maybe one person will get that I was on a ROM when this happened and have a solution for Lg up to see my device as h811

That sounds like a driver issue. When I did mine I was also on a custom ROM. I had to manually remove all LG drivers via the Device Manager and install the LG Bridge for its LG USB drivers before the LGUP tool would recognize it. Before I did that it wouldn't even see my phone.

I would like to think that butt LG up is evidently seeing a connection from my phone to the PC it's just reading the device model as unknown because if I unplug the phone it goes back to reading nothing I plug it back in pops up red box model unknown I know it's reading the phone in LG up because it actually tells you the ROM it detects which is Xtreme ROM by micro mod
Not only that LG Mobile support tool read my phone and says software is up-to-date LG flash tool 2014 attempts to flash but fails because it is not compatible apparently with Android 6.0
Nlg bridge when I try to use that tool sees my phone when I choose update recovery error and says there are no recoveries to update I don't believe it's a driver issue I think it's the fact that I'm stuck on a ROM that is edited in some fashion that will not allow the tool to to proceed to the next step and if you look at the LG up thread it talks about a member explaining about the unknown device model issue is due to the ROM developer editing his ROM name somehow
Everyone that has gotten past the unknown device model happen to have an unlocked bootloader or was just trying to do a regular upgrade and still had an OS to boot into there's just no way around this mess
