[Q] LG Logo than blackscreen (no Download or Recoverymode) - G2 Q&A, Help & Troubleshooting

Okay so here is my Problem. I did nothing with my phone before except rooting. So I wanted to install a custom Kernel with the Recovery, everything went great. I installed the zip and rebooted the device. Yeah, first thing was that it said something like: "Fastboot mode started
, udc_started() " And I had no Idea what happend, but the phone was not starting. So I decided to get back to stock Rom with the LG Mobile Support Tool (because I was still able to access Download Mode). Everything went great again, I hoped everything gets fixed now. BANG. Error at 19 %. I dont know what to do now. Because now, theres no way (really NO way) to get into download Mode again. Everything I try dont works like Plugging in while pushing Up and and and.
Please tell me, what can I do now. I would be so happy if someone has a solution. This phone is so new I dont want to loose it Im a school student this was much money for me.

@Psylou Is there maybe something with qhusb? Cause if download mode doesnt work. The fastboot mode udc started was because the kernel wasnt good.
See the guide no download mode etc.
If you connect your phone to your pc do you see partitions?

I see hundreds of them my whole PC was full of "Do you want to format that data drive?"
And when I hit Yes and wanted to format one, it says that its read-only.

@Psylou good news still fixable dont format those in windows. Dont touch them at all first, read the guide good and then do it.
Btw you need ubuntu for it or some other linux ditribution but I suggest to use ubuntu.

I Did everything said. Everything went great. Now there is no blackscreen anymore, I can still dont enter Download Mode but when i press Down and Power it gets me to the factory hard reset. There I press 3 Times Power, but at the third time just nothing happens . the Bad thing is, Windows dont gets any devices now.

If you cant enter download mode and recovery doesnt work there you maybe did something wrong :/ does adb work in recovery mode or is it pre recovery?

Yes its Pre-Recovery... I messed up. I saw the people on xda with the same problem and no solution. I hope LG will repair it for a fair Price if they repair it. Im so dump I could punch myself rightnow. But thanks for your help anyway you are awesome! At first I thought no One will awnser this Post but you did in like 1 Minute

@Psylou sorry for your phone I think something went wrong. But I dont know what :/ Maybe there is still a way to fix but I think you kinda bricked it sad that it happend on your phone so fast even when it was new worse well goodluck mate I hope you can get a working phone soon again :good:

There has to be a way to fix it now. The Repairing costs more than the Phone. I mean I dont even know how to get in Fastboot mode or using ADB. Can you help me with this? Maybe this is working.

@Psylou sadly you cant boot into fastboot just like that without a modded bootloader. I dont know how adb should work if recovery mode doesnt even work. Sadly I dont have a solition atm

First thing if LG could fix it like that without replacing like the motherboard then I think it's okay because I don't like it if things even under warranty are going like that :/ but yeah then you are also again paying warranty so its like 50/50 of good and evil.
But what you could try is maybe make a second try and say that it was like that after a reboot or something idk, I never really returned anything in warranty and or bricked anything. Just make the second try maybe in 3days or maybe after a week. Btw did you also gave them your Imei etc information? If so then the chance is smaller you can get it fixed under warranty.

Just to say. I got my LG back and repaired for free. without telling them false storys. I told them everything and with a little bit of sadness they said, that I could have the warranty paper to send it there. This happend 4 Months ago, but this post reminds me to say that it worked great.

Might buy boot-looping Xoom, questions

Hello,
So I bought my Xoom over the weekend when I never heard back from a Craigslister about a Xoom they have that is bootlooping.
Finally got back to me today and I am looking to fix it, and make a little profit.
Guy explained he knows it can get into Fastboot and mentioned RSD lite so I know he has done some research but ultimately he said he is not good at computers and cannot fix it.
My question is what do I need to consider? If I can access hboot ( from power off wait til see M and hit Vol - right?) I should be good to go is my understanding. Is there any way to run a diagnostic and see if there is hardware issues going on?
What would you do I guess lol
He said I could tinker with it first. I am familiar with ADB and rooting / custom roms on Android but have only had my Xoom for about 3 days.
Thanks
If you can definitely get into fastboot, you can recover it; simple as that. Whether there are hardware issues is another matter.

The question is, how much are you willing to pay if you can't fix it, then if you can you will be happy, if not you should stay happy.
Bootloop can be software but they can easily be hardware too so better be safe than sorry
take a laptop with you and do "fastboot devices' on the spot.
If the computer can see it then it can be wiped clean and fixed
It's $300 and it wouldn't kill me, obviously wouldn't be ideal but not the end of the world either.

That's what everyone told me when mine went into a boot loop. I was able to flash the new images in fastboot, but it never came out of the boot loop.

@OP
If seller knows about Fastboot & RSD Lite, he's probably on this forum. Might even be in this thread.
HEY SELLER just let me figure this out and I'll buy it right off ya, OK?
If you CAN get out of it that certainly a very good price. Most cases I think I have seen have been recoverable. Maybe ask the seller how he got into this situation in the first place, might give you a better understanding of how to fix it.

Installed Chainfire 3D now stuck on boot screen HELP PLEASE!

Hello,
I installed chainfire 3D ( Yes I know I should have read that jelly bean was no compatible) and am now stuck on the boot screen of my phone. I have got the factory hard reset menu up but don't know what to do apart from that. I have checked on other threads and they are all really confusing for a person that is new to android. Any help would be greatly appreciated. Also can I just permanently erase user data or will this brick my phone?

If you had cwm you can use adb to remove the .apk via recovery.. twrp even made it easier by having a file explorer inside the recovery..
But if you haven't installed them both i'm afraid you're out of luck..

Recovering your phone at this point wont help you at all my friend :/ you have officially bricked your phone sadly this is beyond my level of expertise in the smartphone world i would take it to a local rooting/roming buisiness on craigslist or i think cricket will do it... call them up and let them know your problem detail for detail they will probobly tell you you soft bricked your phone there is a slight chance they may be able to fix it for 15-50 dollars depending on how bad it is
Can you still get into TWRP or CWM recovery?
If so then you can probably still use an adb interface to push a ROM.zip file to your phone to flash. If you cant then Im not sure how you would go about fixing because we do not have an unlocked bootloader so I do not think you will be able to use fastboot commands to flash a ROM. Maybe someone more knowledgable in this can help you out better than I.
same thing with me
Dude the same thing had happened to me on my gionee p3 and i tried everything but u have to just take it to the service centre and i got mine done for free as i had a warranty but if u dont u will have to pay and also this happens when u download **** things that take the main startup programs of ur phone
.....so best of luck

Weird error flashing back to stock. D800

Background
Phone: LG G2 D800.
Where problem Arised: Flashing Paranoid Android Rom, missed a step. Forgot to install the boot image (I think)
Current Things not working: TWRP Recovery disappeared ( I really have no clue what the hell happened to it. Just not able to get into it anymore), Phone is in boot loop at PA loading screen. Using LG Flash tool , I keep getting an error telling me that I have the wrong .bin for my phone, but I'm certain the dll and tot I attempted to install are for my phone model. Meanwhile, LG mobile support tool freezes when trying to check my phone settings.
What is working: I can definitely get into download mode. So maybe there's still hope.
Any help guys?
I'm seriously stumped. Gonna maybe try emergency on LGNPST
I think this is the definition of hard brick. send it in, paid the cash to get it fix, get it back, read instruction carefully and flash.
Any good services you know of?

On this topic, do you know a good place I can send it in to be fixed? And what method do they use, if so?
Cause I'm only really going to send it in at this point if it's a jtag flash. They tend to be really quick, and I haven't lost hope with it just yet .

Deep, Deep Brick (LG G2 D802)

Hi guys,
After a long search on XDA, unfortunately I couldn't find the answer to my problem, so need to start a new threat.
This is the case: phone is on 5.0 CM12, tried to install twrp on it via the twrp market-app. When needed to reboot phone went dead and wouldn't turn on anymore. Tried to reflash firmware but my phone won't boot into download mode. When trying to do that, my pc just opens 7 screens with removable disk E:, F:, K:, L; etc.
In computer manager it also won't show the LGE port, which I would need to use to repair my phone. I never had something this bad before. Does anyone please know what to do?
Thnx in advance very much!

Thnx mate.. only one noob question: how do I boot into Ubuntu?
I don't really know a lot about rooting either but I can tell you that you, well, have to have ubuntu installed as your OS.
anyways me and my brother tried it and it didn't really work, because the G2 was only connected to the laptop for a few seconds.
I just wrapped it up now and im going to send it back tomorrow. I hope I'm lucky... good luck with your brick

I discovered super brick

Yes folks,
As I said, I discovered SUPER BRICK, TOTAL BRICK, COMPLETE FAILURE or whatever yoy want to name this new brick. It has been like this: I was following the instructions to update oreo in HONOR 8 LITE, at the end I had to write some codes in twrp (advance / terminal ...) so it was starting to do the last update (sd card update.zip) and by accident I touched the screen where it appears: REBOOT, so the phone restarted but the screen is not working when it tries to enter erecovery mode, so here is the list of my problems:
- it does not work: erecovery (so I can not recover the phone)
- fastboot works: when I install something (twrp or firmware, I have tried everyone of them) the phone does not start
- if I try to go to TWRP (after installing an oreo one): the screen seems to break and you can not see anything
Please, my phone is 2 months old, man I need to make it work again, I need it.
Help help help
You should post this in Honor 8 lite forum ...
But whatever, you said that fastboot works if so you can try to use huawei update extractor and flash system,boot,recovery,cust that *should* work

There is a way to fix that.. but... Its too complicated and hard to do..
Since your phone is new, you probably dont want to buy new.
This is going to cost you a bit.
First you will need to find honor 8 lite or p8 lite (if you say they are the same)
that is well.. dead, open it take out a memory chip on both phone and place chip from dead phone to yours. If you dont know how to do that take it to the repair shop and they should know how to do that.
As i sad its very hard and it costs, but it works if done properly.
I saved my friends phone like that, idk what he did but phone wasnt visible in adb, fastboot and recovery didnt work just blue screen.
Note:
This needs to be done very carefully or ypur phone will be 100% dead

DC Phoenix worked fine, it's been awesome, I installed the rom and my phone is alive, I wonder: why I couldn't do it with ADB? Why this software is so powerful? And finally, why nobody is making kind of software like this for free? I mean, dc phoenix must be like the software that Huawei technicians use in their lab and samsung has ODIN that is so powerful as well and is free.
Anyway, if anybody has a problem as mine, you have to pay but it has solution. By the way, I went to tech service and they did not do anything because I bought my phone in China and they could not touch more than european phones, but they told me something that made me think that my trouble had a solution: rewrite the rom and that point convinced me that DC Phoenix would work, and so did it. Thank you all for the info.
Same for me, how to fix please. Bricked following this "guide"
https://www.haky86.com/2018/05/12/install-emui-8-0-huawei-p8-lite-2017/
I was on official Emui Nougat, wanted Oreo, forced update with nocheck, everything is broke except fastboot.
When I want to flash his OreoTWRP.img with "fastboot flash recovery_ramdisk /path/to/img" it work but can't reboot to recovery.
I press Power + Vol+ but it reboot "phone untrusted" with Vol+ for going to eRecovery (usualy it's here you can shutdown the phone) but error mode.
Maybe the OreoTWRP work after my command but can't boot into it. Please help.

Bro my P8lite is also bricked, I accidentally wiped the EMMC then I showed it to a repairer and he somehow took me to fastboot mode, now I can't flash anything because that repairer has partitioned the EMMC and now it is showing 486mb total storage so no ROM is flashing because of size. Can you please give me your USERNAME and PASSWORD of DC Pheonix as you've already bought it. It will solve my issue and it will also save me some money.... I will be very thankful to you....
WAITING FOR A POSITIVE REPLY.
I bought it some time ago and it was a 72 hours license and it expired so I do not have anything from that situation. I will check my computer but I will not probably find anything.

Hello just looking at that pic is enough. That happens cause you installed the wrong firmware. Either get a proper nougat rom for your device and install boot, recovery and system images from fastboot or a oreo version. Either way that screen means its the wrong firmware version or wrong zone. for example you can be trying to install a europe rom in a asian device. hope this helps
