[Q] Soft Brick Issues, What Can I Do?

Hi Everyone,
I rooted and used TWRP. Everything was fine, got SU installed and what not. Then I downloaded CM 10.2 Snapshot and Gapps and flashed them for the G2. I got the fastboot error. After trying to erase and replace the recovery, I found this thread http://forum.xda-developers.com/showthread.php?t=2448960
I get all the way to the last step when I use the LG flash tool and it says "Dowload FAIL!" It says Device Model is different! The LG Flash Tool shows I have a D802, but my phone is branded Verizon and I had LTE working on it earlier today...so I assume it isn't the GSM version...Anybody have any idea what to do?
I'm a new user, so I can't post external links, but here is an imgur address Ea8zgf7.jpg to a photo of the issue
Text on phone in the download screen says "VUSER S0.0 AS0.0 B82 UHS (New line) S US LG-D802 04.3.1 Hrev_10 (new line) VS98010B
Unfortunately I keep running into tons of dead links for different ways of dealing with this issue. Now I'm really concerned that I'm going to get screen burn in because I cannot shut the phone off. It either sits in the fastboot/error screen or in the download screen / firmware update screen.
I would really appreciate anyone's input. I tried to use this link http://forum.xda-developers.com/showthread.php?t=2432476 But almost all of the links are dead.

Was this ever solved? I have the same problem as the OP except with my ATT LG G2 D800. The lg flash tool shows my device as a D802. I have even tried downloading the D802 firmware, but got an error about the laf memory.
Like the OP I have followed other posts, but never found a solution. Please help.

I have an update: I used the procedure to do a factory reset by pressing the power and vol down until the lg logo appeared then release the power and immediately press the power button again. This prompted me to press the power button to do a factory reset. It came up with an error, but then booted into the CWM which I was using to flash CM on my device.
Hope this helps others.

Hi, I know this has been way back from 2 years ago. But is there any solution yet? Mine is ls980 and I'm having the same problem. Somehow trying ti factory reset does not work as after I released the power and volume down button the screen goes dark immediately and if I press it too long it just turns off.

Flash a different ROM
Ok, I hope this will help others:
I have an LG-H500F from Telcel Mexico, it got the security error bull after rooting and uninstalling bloatware, I could not find the original ROM anywhere but I found one for LG-H502F which is basically the same phone but for two sims and tv tunner.
Anyway, trying to flash the 502F Rom to the 500F kept giving me a download error complaining about not being the same model so what I did was, opened the dll file in an hex editor and found the model part H502F so I changed to H500F and saved it, also I changed the name of the tot file to H500F and Boom! It flashed it and revived my bricked little toy!!!
Hope this helps...

tried to upgrade to kitkat, ended up with bad touch response

i just received my new G2 D802 16GB,
i tried to upgrade to kitkat with this guide
(flashed Switzerland 16GB D80220F_00.kdz)
i ended up with a phone that wont boot, it got stuck it fastboot mode, i messed with fastboot until i got to the point i had download mode again, (i messed with the partitions: sb1,tz,laf...)
i tried flashing many roms (Europe Open D80210A_00,UK Open 16GB D80210B_00,Hungary OPEN 16GB KitKat D80220B)
the roms load fine, but now the touch response is unusable (touching a point is being registered in another spot altogether).
this happened with every rom i have tried.
i tried with the tot method from the same thread, i got memory Size mismatch 32G! error (i have a 16GB model),
i tried the tot again with the 32GB rom and it passed, but the problem remains (the bad touch response).
what do i need to do?

Why didn't you just use the PC program to update?

Maybe you can try that thing from update touch driver or whut from hidden menu.
I also read that some people also had this issue on kitkat but not on jellybean stock
So try some things and report back :silly:

Yes I meant that Step3 from that url.
What you can do is 3 things.
Downgrade to 4.2.2 :/
Connect an Usb OTG mouse to your phone.
Try or OSP(On screen phone) works.
If these things don't work then you must try to find something else cause further then this I don't have any Idea at the moment, maybe later...
Goodluck:good:

thanks,those are 2 great ideas i wish i had thought about!,
i sent the phone to be serviced, i will post here the outcome if that matters.

Ahh okay, sorry for late reaction was busy with school.
If your phone gets serviced then they will also probably ship it back with 4.4.2 stock and also with normal working touch .
you can post the outcome if you want I think
Just wait for it till you get your phone back, then you will be happy again

Update your touch software from service menu and you should be okay.
Check xda for. Service menu code

i bought this "d802" online, the box, phone sticker and "about" all said it was a d802 (normal back panel, no "ATT" logo),
after i opened the phone i discovered the logic board is actually a d800.
i managed to change the model number in build.prop (to d800), and flash the d800 with the tot method, the phone works fine now,

[Q] Did I brick my phone?

Hello,
I have a LG G2 (D802). I was busy flashing the stock KDZ, when I got an error. The progress on my phone stopped, and nothing happened anymore. I wanted to try again, so I turned my phone off. Now, when I boot my phone, it gives the LG logo, and then nothing. When I connect it to my pc, I get a lot of format pop-ups.
I followed this tutorial: http://forum.xda-developers.com/showthread.php?t=2432476
The KDZ I used: Netherlands Open 16GB KitKat D80220D
Furthermore, also while connected to the pc, I only see a folder called "image".
Can someone help me with getting my phone back to stock? It doesn't matter if everything gets wiped, I already backed up everything.
Thanks in advance!

If lots of drives still pop up when you connect your phone to the PC,then follow this guide:https://www.youtube.com/watch?v=hQVTc2m6U-I
I did it,and it fixed my download mode,and I could finally access Download Mode.
If your Download Mode still works,try the TOT method,it worked for me,since the KDZ method would be stuck at 2% every time(in my case).
So,after,or if your download mode works,do try the TOT method.

Just dont panic,even if your phone is in a "hard brick" state(doubtfully),there is a fix for it too.
I suggest you do not do anything without consulting with other members.
You just have to be patient.

Oh,and go to the Device Manager and tell me what name your G2 has when connected to the PC.

Download the kdz suitable for your model and flash it with LG Flash Tool.
Follow the "Back to stock" guide which you mentioned in the OP.
There will be a link to the KDZ archive for various models,and make sure that you select the kdz for the 32 GB variant if you have a 32 GB variant. Because it will be dangerous if you flash a 16gb variant kdz on a 32 gb phone.

And if the same thing happens when flashing,fix it again(if it won't access the download mode) and try to flash while using another PC.

Yes,excellent job.
To root,download "Towelroot" to your phone,install it and press the "Make it rain" button,then install SuperSU,then look for "AutoRec" and make sure you get the version for your variant.

It is complicated,just do it. XD
I was asking the same thing like you.I ignored others,rushed with roms,didnt use the BUMPED TWRP and my phone was bricked.
Basically the TWRP you get with AutoRec is just capable of flashing partitions for the bootloader,not the system partition(the rom is in the system partition).
The BUMPED TWRP has a certain type of an exploit,and lets us install those system partitions.
Shortly:You can't install roms without the BUMPED TWRP.

I'm guessing my phone is refurbished?
I bought a D802 from a third-party, with:
- 32GB ROM
- 4.4.2 D80220b firmware
- 2G, 3G, 4G working
- The csmg.lgmobile.com website said that according to my IMEI, my model is the UAE 32GB D802 and gave me the D80230a firmware for manual flash via LG Flash tool.
I used the phone for a while, rooted it and used Xposed. Never got recovery so no backup(wish I'd seen the SRK tool before). Then I downloaded the firmware from the csmg.lgmobile.com website. I flashed it via the Flash tool and everything seemed fine. Then it booted:
- Touchscreen was erratic. Ghost touches, dead spots, phantom touches, whatever.
- The Baseband Version and IMEI in About Phone both say Unknown
- ROM has converted to a 16GB version
- Download mode is fine along with every other feature of the phone
After that I looked around and found a UAE D80220c firmware and flashed that. It flashed fine but all the above issues remained the same.
I browsed around extensively here and found out:
- Refurbished phones have their back cover and firmware changed to imitate D802's.
- My phone is probably some other G2 model with D802 firmware and an altered IMEI
- The actual model of my device is UNDER the motherboard. Which, apparently, I must get hold of so I can flash the appropriate stock kdz. This gets a bit too hardware-y for me.
So, basically, my phone is no more useful than a brick at the moment. Any expert help would be appreciated but here are the main questions that I'd really like answered:
A. Should I try various flashing the kdz files from different models mentioned in the link I gave up ^there until one clicks and then try to do something about the IMEI?
B. Is there any chance that my phone is beyond repair forever?
C. Should I stop messing around with my mediocre knowledge and take it to a repair shop?

Which firmware to flash in Lg g2 ls980 (sold as d802)?

Hi, i recently bought an lg g2 which is actually an ls980 but sold as d802. I ended up flashing the wrong version of firmware. Earlier i couldn't boot into download mode, but i fixed it using the qhsusb_bulk method.
I've flashed 3 versions of the d802 firmware but none of them actually boot. So i decided to open the phone and see the actual model number of the phone. There was written ls980 on the back of the motherboard and on all the parts. So my question is that if i flash the ls980 firmware, will it super hard brick the phone? I see no other way to get the phone working other than to flash the ls980 f/w.
Some advice needed. A quick reply would be appreciated. Thanks!

Did you check the IMEI to see if the the phone is a D802 or 980?

Yeah i did check the imei on the internet. It says the phone is d802. I've also heard that this source is not completely reliable to determine a phone's model number. But the phone's motherboard says ls980. I'm thinking to trust what's written on the motherboard itself. Should i proceed with flashing an ls980 rom? Please guide me. Thanks!

Sounds to me like the motherboard is from a 980. Did you try using the LG upgrade tool (not LG flash tool) to perform a recovery? The program should provide the model #.

I didn't try using the upgrade tool but I'll try that tomorrow and give you an update. But any d802 fw i flash: jellybean, kk or lp, the phone just doesn't boot up (it gets stuck on the lg logo w flashing led). That is the reason why i believe that it's an ls980. Anyways, I'll try using the upgrade tool.

my phone's up and booting once again but I'm facing two problems now:
1) invalid sim error (I'm pretty sure it can be fixed without too much effort)
2) very low wifi range. The wifi icon shows only one stick even if kept only 30cm away from the hotspot (the hotspot IS working fine in the other phone). Any help with this?

Not sure what can be done about the invalid sim other than checking to see if the phone is network unlocked.
Have you checked for loose wires inside the phone? This may be causing the low wi-fi signal.

pretty sure that the wires are fitted properly. But there's no harm in double checking. Lemme see...

I have faced the same problem you are facing bit is solved. Please try and root your phone first. Your phone model is ls980. So flash it with pc with this rom "Ls980zve_03.51102.tot and lgls980_20130904_lgflashv151.dll to do a clean flash with lgflash tool.
After that if you want you can root it with stump.apk . and autorec.apk for twrp recovery.
To me Ndm 5.5 inspired Ux Lollipop G2(Allvariants).zip is the best rom.

Bricked LG G6

Hello everyone!
To make my problem short I tried to update my LG G6 on Oreo but in the middle of update process phone shut down(I didn't know why-probably battery?) And after that phone is bootlooping and I tried to flash stock rom using uppercut and LGUP but without success I manage to start flash process and when it reaches about 50% phone just reboots and flash tool gives error message. Now phone is bricked. I don't now if there are any solutions. Any help is appreciated! Thank you guys! :fingers-crossed:

Keep on charging..
See some post how to enter in download mode (within fraction of second).. use LGUP and flash PROPER ROM..
(I see it was bootlooping.. that it must be charging)

Huge thanks for your reply, well I manage to get to download mode without problem, PC can detect phone as well and I can start flashing process, however with all firmwares I have found I cannot "refurbish" because "refurbished is not supported by that firmware" so I can only select upgrade in LG up. When I start process it goes all the way up to about 50% and phone just reboots back to download mode, after that LG UP moves a few % further reaching about 55% and gives error " invalid response code". I think if I can somehow use that refurbish option to clean flash stock rom , maybe that will be the fix. Thanks again.

I also forgot to mention that when I failed to install stock room with LG up my phone cannot escape download mode, when I force reboot it phone goes again directly to download mode. Probably because there is no OS installed?

Are you sure to using right firmwares for your model?

Thanks for reply. Pretty sure I did use good firmware I found links here on XDA forums and downloaded "H8710d_00_OPEN_EU_OP_0327.kdz" but if I somehow found .tot file would that make a difference and let me to use that "refurbish" option. Thanks everyone for help, very appreciated!

Hi Ray, can you provide me the link of the tot file? I have the same problem

Unfortunately, I think there are no tot files that support refurbish. But after I replaced motherboard regular kdz update flash worked perfectly. I haven't found solution to that problem.
I would suggest you to try your luck if you have unlocked bootloader and try to flash TWRP to get phone back.
