[HELP] Hardbricked G3... :(

I am Done.
It's not booting, it shows LG splash screen and after some seconds dies.
I tried everything...
my last resort was using LG Flash Tool and flashing the .tot file...
First time, it went good, even reached where the 2 Factory Reset Status, where it froze though. Followed a guide saying I need to select Board DL, tried but no good.
Now, when trying to flash again, and reaching where the phone has to reboot, it shows the LG Splash screen and dies again, sometimes, it shows the Demigod Crash Handler saying either Kernel Crash or Tz Crash.
No one seems to want to help ...

Vibe K5 doesn't boot up

hi, I need some help, i'm desperate.
I was using a bad charger, when my phone was in low battery, so it turned off my phone (charging > not charging) three times. In the third boot, the CM logo just froze up, and the phone didn't boot anymore. It appears Lenovo's logo and then the screen turns black and i'm not able to press any button. I tried to: wipe everything, flash another rom, but the same still happening. I flashed stock rom too, but it gives me a bootloop. I tried to use a TWRP's backup from stock rom, but it didn't work either.
Any help? I don't know what to do

Since you flashed a stock rom , flash a new twrp using adb and fastboot and wipe everything except system . BTW a simple reboot (or three) cant damage system. Try checking battery too if you could

I tried that with QFIL and Lenovo Smart Assistance. and bootloop.
But I think i've made some progress:
I tried to flashed a new rom (I flashed CM/RR/AOCP before, is with these roms the frozen lenovo screen happens), CRDROID, and it appears crdroid bootanimation, and load until it frozes and phone turn off.

1) Main problem is Battery backup. It won't last long a day.
2) Stock ROM Really sucks
There is no heating issue though. It has been solved by latest updates

Try entering to TWRP by using the hardware keys. Do this:
Pull down the battery.
Insert again.
Press power key, volume up and volume down at the same time, until lenovo logo dissappear.
If luck, you are into TWRP now.
connect phone to computer via usb cable. you should be able to access to internal memory.
So, copy into it any custom ROM previously downloaded from your computer, and flash it. That's all.

Bootleggers has some bugs, like WhatsApp not being able to play GIFs or videos. Also, after a while in the day, launcher becomes laggy (maybe a kernel settings issue). You have to reboot and becomes smooth and fast again.
I highly recommend LOS 15.1 or AEX 5.6 from Harry (yes, he is continuing the development!) Both of them have June updates.
I'm on AEX right now, which is such a marvelous ROM. It has a looot of customizations than any other ROM I've tried.
How to get them?
Search into the Harry8242 profile from AFH.

LOS 15.1 is fine but has some bugs too(camera zoomer not working).
I've finally decided to use a STOCK ROM and there is a complication, here is the problem:" I'm using lenovo downloader software to flash and once my phone is connected, the progress bar gets stuck at the begining level and says:"Flashing" below the status bar and " Sahara "- which have no idea what means- below the step bar and it also takes too much time to do the flashing which is never done! I have the same problem with QFIL( Sahara Fail )!

Glad to hear that! So, you've decided to stay on stock ROM. OK, it has sense. stock firmware is free of bugs, right? Now, do you know being on stock LL you can "update" to MM and thus get doze and adaptive storage?
How?
Follow this guide:
https://forum.xda-developers.com/k5-plus/how-to/guide-a6020l36-official-lenovo-andoid-6-t3596733
and you'll get the most updated official stock ROM available four our device. Actually, it's a backup made by an Brazilian user, where you should restore only system and boot partitions, in order to keep your data.
This update was only released for Brazil region, but, users from other regions in the thread, reported it worked for them.
I've tried it once, and worked like a charm.

Heelp pls. !!!!!!!!!!!!!

Go into recovery and reflash your rom again. As long as you do not wipe all your data will remain

It's bootloop issue,I think.i had bootloop issue,so this "flashing all kdz I can find for my phone" is what I did-and nothing helped,always never-ending boot or bootloop or nothing.Only way to make it work is,flash 5.1 kdz for your phone with LGUP(you need unlocked bootloader for this),and than flash "disable big cores on 5.1" file using LGUP.then it will boot.But it's still broken phone,TWRP won't work and custom roms/kernels won't work.

Bootloop, soft or hard?

Hi,
I've got H815 stuck on LG logo. I've tried flashing stock fw, the I've tried the LG Bridge way, all of them completed but still stuck. Then I've tried the hard reset but no luck. Is this hardware issue then?

I've tried that already. Flashing goes well, but then it's still stuck on LG logo. Another thing, when I leave the phone without the battery for night, then in the morning it boots up up to optimizing apps, blue led flashes but then goes back bootloop. Some people here recommend lgup with different dll files and particular fw but I don't know if there's a point.

Yea I unbricked my bootlooped H815T with thiskdz give it a try..

I got this phone second hand and the guy said he was trying to downgrade fw, after which the bootloop happened. Is it possible that it's just the anti-rollback and not the faulty motherboard? How to make sure?
My phone is in the freezer now and we'll see how it goes...

I've just tried something that definitely prooves that's hardware issue. I've disabled big cores using that guide and phone works now. It's just single core though. You can make images to run on 4 cores but it's only temporary solution and I'm afraid the phone may die at any time. I think I'm gonna do the return but the guy is not really happy to do that.

Maybe try to unlock the bootloader and flash twrp. It's what I would do.
Best of luck

It is unlocked. I'm just gonna return the phone. Guy sold it as having a software issue, but disabling big cores proved it's an infamous LG ilapo. It can run on 4 cores, there are guides how to do it, but you can never be sure when it dies completely. Thanks for help anyway.

Hi there,
I've been exactly there with my H815. I have tried numerous solutions, but to no avail. On your reddit post I saw that you tried the recovery key combination and ended up in download mode again? Did this happen, after you pressed a button? With my phone, when the LG factory reset screen appeared and I confirmed twice, a long time nothing happened. After a couple of minutes the Android recovery (not TWRP) screen appeared. Maybe you'll have a chance to get your phone recognized via adb sideload or sth. Or start fastboot mode. Maybe you can reflash TWRP? But if you are facing the same problems as me, it probably won't help you.
For me, I ended up sending my phone to LG, despite the fact that the warranty was void. They changed the mainboard and never said anything about repair fees and apparently the phone is on it's way back to me as I write. I hope it arrives tomorrow and I can let you know.
Hang in there! :fingers-crossed:

My warranty is over ( 2 Years ) Do you think I could try ?? (Bootloader unlocked/ Custom rom and recovery have been installed)

I cannot give you any guarantees, as I am not associated with any LG support haha. Technically, I am still on warranty, but as I also unlocked the bootloader, installed Custom ROMs etc... the warranty would be void anyway.
I got a reply from LG support that i should send it to their repair shop (some shop in Germany) and they would reply with an estimate of the repair costs. Now, all I got is the tracking number, the phone's on its way home and they did not charge me at all (as of yet). So you could be lucky, but you very well may not be.
I'd say, take your chances and contact LG support, send it in. If they want to charge you a huge amount of money, they can still send it back to you unrepaired and you might be able to fix it yourself. In any case, I wish you the best of luck!

the thing is after you have flashed TWRP you HAVE to boot directly to TWRP afterwards. otherwise it gets overwritten.
You can also setup SALT and depending on what your current firmware is you can flash TWRP with SALT too.
For that IRC is much better though http://webchat.freenode.net/?channels=carbonfusion-user

Hi,
A belated little update. My phone has found its way back to me and is working perfectly again. The main board had some dysfunction, it was exchanged.
LG didn't charge me a dime, so I can't complain. Flashed LOS 14.1 just now and everything is running smoothly. Hope you had some luck with your phone as well?
Cheers

Ok I tried everything with salt, with the motherboard ! Last thing I can do is to contact the support ... Waiting their answer and i'll tell you the feedback
