hello guys,im new here i need your help..
I bricked my d802 today,i was on stock kitkat rom,what i did was rooted my device with towel root and used Autorec to install recovery,it installed successfully,then i clicked ''go to recovery'' then all i get were white lines on one side of screen and rest of screen is black(cant see anything).. after digging for hours i came to know that it is because of different Kernel version,but now i want to know how can i flash patched Kernel? as my device is bricked.. It is also not going into download mode so i cant also flash a stock rom.. tried Adb but it is not detecting my device... im completely lost
A tutorial or help will be appreciated.Thanks im waiting for your replies
EDIT:
i used fastboot commands n flashed some img. files..now my display shows up(dull white lines are still on it)..i can boot into download mode now..i flashed kdz stock rom it completed successfully.. but after reboot it is stuck on lg logo with led on... i did hard factory reset(holding volume down key + power button) but it is still stuck at lg logo.. i can still boot into download mode and i dont have a custom recovery installed what should i do now?
can i flash custom recovery using fastboot command? because ADB is not detecting my device. but computer is detecting my device(it also installed three drivers automatically)

none bro....i sent my phone in to an XDA Super Contributor in the LG G2 section. He was in California. Try to find someone to help you around your city or country. Sorry man. If he gets it done, i would ask him how he went about it and let you know.

Hello
I have bought my Lg g2 d802 few days ago and when I tried to root it and install recovery using autorec the phone screen went black after rebooting into recovery and still in that state.. no led, no download mode , no recovery nothing else just white lines on left corner.... I tried it to get its software repair but they said that the lcd has been fused and need to be replaced ...
I tried to connect it to pc and it is showing marshall london adb interface and in another pc it is showing Android with yellow mark which turned in to Android adb interface after installing drivers from internet
I tried fastboot.exe and adb.exe but no device found error in adb mode but some commands working as fastboot..
I want to know which partitions u flashed using fasboot and how because when i tried to flash it says cant load XXX.img (xxx belongs to the name of partition i flashed)
same problem is here....u found any solution???
AutoRec got my LG D802 bricked and now all i see white lines on screen. Can anyone help plzzzz

LG G2 Bootloop Bricked - No recovery or Download mode

Hi guys, I might need some help or a walk through here, I might have bricked my phone. I stump-rooted my phone ( 4.4.2) and installed TWRP Recovery 2.8.1 initially , Installing SuperSU which patched my sdcard and rebooted causing my phone to get stuck in a boot loop giving me no access to download mode, just recovery. From there I tried to install Cynogen mod 12 in TWRP recovery to fix the bootloop but any attempt at flashing gave me an error "error executing updater binary in zip." So I extracted the folders and flashed the 2.7.0 recovery.img which sayed it worked but now my phone is still stuck in boot loop, no download mode and when I try to enter recovery I get stuck in fastboot mode with port change errors. I took some screenshots so it would be easier to help me out. Every time I plug in the USB I get the following errors, the screenshot is from continuous attempts
I have the mini sdk installed and Koush drivers. Device manager does not recognize my phone anymore but it does come up under Fastboot Interface
Any Help would be greatly Appreciated
Because I'm a new member I can't post screenshots so just add an h infront of the links.
Thanks in advance for all your help

Can you please explain how to do that WITHOUT entering download mode?
Maybe LG Flash recognizes your phone and will do the job.
LG Flash does not recognize my phone at all. http://forum.xda-developers.com/lg-g2/general/lg-g2-unbrickable-fix-real-hard-brick-t2904404 Do you think this method will work?

Bricked Zuk Z1

Hello,
Ok, here is the situation
I have a Zuk Z1 with last COS update 12.1 with locked bootloader, no root etc ... (I didn't touch anything).
Yesterday, it reboot by itself but I got bootloop (starting apps then again lenovo boot image ...)
I try to factory reset by using the recovery metohd, it's start normally (optimizing apps ...) but then reboot and again bootloop ...
So I try to sideload the official COS ROM from Cyanogen Support (cm-12.1-YOG4PAS9IG-ham-signed-d4fc2c5394.zip), but the sideload stuck at 47% and saying total xfer: 1.00x and the phone go back to recovery but still have boot loop ...
I try to boot in fastboot and use the All In One tool to flash official ROM but didn't work (Its say that the bootloader is lock)
I find without knowing this menu a debugging hardware tool test, and then I run the test, its say SD : Fail and in another I got SD : Fail and no sd fuse in dir
I saw many thread here and on google, and some say that we have to use qfil/qpst method, and find this which seems complete : http://www.androidbrick.com/lenovo-zuk-phones-qfil-roms-unbrick-guide/
But as I don't know if its hardware issue or soft brick ...
Could someone help me to recover my phone to COS or CM by using the right method ?
Thank you !

Go with qpst/qfil method to recover your phone
And did you tried changing the USB port or cable while side loading cos ROM .. Cause most of issues are solved by the changing USB port or cable.. So try this.. Or else qfil is the option

Hello,
I got help on the telegram group, we try many thing, the result is that I can only get ZUI working, if flashing COS via QFIL, I get the same result, if I flash ZUI, unlock bootloader, flash TWRP, wipe everything, then sideload CM13, TWRP say that no os is installed and I get a bootloop at the bootloader ...
ZUI is good, but I get some error regarding notification.
If you have any other idea ?

It only sees my device as a composite device. I can't use fastboot as long as i don't know how to do it and how i can connect my device to pc . Please help is there any way i can get out of bootloop via sd card from recovery mode?? I am exhausted reading and searching and watching tutorials....Thanks in advance.

Still no one to help??

Hi,
can you flash a ROM using SP-Flash Tools? With SPF you don't need the mobile to be switched on. Of course drivers for MTK must be installed properly before doing this. Maybe clearing cache and Dalvik could help as well.
