I know that there are loads of threads on XDA regarding bricked G2s (and how to fix them), and believe me, I have scoured every one I could find. None of them had the same situation as me. Here it is:
- tried upgrading rooted G2 (d802) to KitKat through PC suite
- on reboot, phone gives repeated "Unfortunately, com.android.systemui has stopped" messages
- this prevents me from doing anything - cannot start developer tools/USB debugging; cannot software factory reset; may as well have a broken screen
- tried booting into recovery - there seems to be no recovery
- I have booted into recovery before the update; I tried using the same method - nothing
- I googled for alternate methods, none of them worked either
- has download mode - what does this enable me to do?
- tried using a 'restore to stock' flashing tutorial on XDA - didn't work
- it is here if anyone was curious
- cannot access through ADB
- TWRP gone
- have no idea how to access through fastboot
Any other options available? Is there any other way to enable USB debugging, trigger fastboot, access the phone through ADB, or factory reset it?

ok well first entering factory reset(or custom recovery)
-before d80220d the key combination to enter factory reset is with phone fully powered off hold volume down+power and when lg logo pops up let go and hold volume down+power
-after d80220d(or any update that includes knock code) the combination was changed(pretty sure it had to do with the fact that on kitkat we used stock recovery to install root and everyone who couldn't get in via adb just had to use button combination which everyone knew) and the new combination with phone fully powered off is to hold volume down+power and when lg logo pops up let go and hold onto volume up+down don't touch power, if you have tried these then you should mention it

You are an absolutely beautiful person. I think I have fallen in love with you. THANK YOU SOOOO MUCH! I swear I found at least 5 different tutorials and none mentioned this.
If your name doesn't go down in history, the world is cruel and unjust.
Sorry. But thanks. SO MUCH.
Im facing the same problem, wanted to go back stock and had CloudFlexy 2.3 installed. Did the firmware flashing, got stuck with procesesses stopping and couldn't boot into factory reset.
Found this thread and got to factory reset, tried factory reset but now my phone only has android figure with spinning thingy inside of it going on in my screen. ADB wont recognize the phone.. I think i need to flash stock rom or something but not sure how to. Please help, how did you proceed rtswan1211 after getting the factory reset screen?
Edit:
After waiting for 'bout 10mins for something to happen i just tried to reboot the phone and still the same spinning android logo came on. Finally plugged in the USB cable and phone booted up with working software. Had me really worried.

after tried several times, FACTORY RESET successfully done.
Previously, I updated the 20G through custom recovery and forgot to wipe clean. After completely installed the 20G, error shows blocking the screen and the custom recovery was gone. after several attempted, I succesfully done by:
- turn off the phone completely
- press vol down and power
- release immediately, upon LG logo pop up, and
- press vol up and vol down
- Factory reset menu pop up
Seems now is harder than before, I need couple times to try before succeed
Hey guys,
I unlocked my Nexus [email protected] via fastboot oem unlock. It worked so far, the device rebooted but was stuck in a bootloop just showing the animated bubbles. So i bootet into bootloader by pressing power + vol-dwn to perform a factory reset. Now it bootload it says Downloading... Do not turn off target!! beneath the android icon with the open front.
Besides this my problem is, that I cannot select Recovery by using the vol-up / -down buttons. It just says start as if there is no alternative.
Is there any opportunity to perform a factory reset / exit the bootloop?
Thanks in advance,
Calle
Hi,
Unlocking the tablet effectively wipes everything. Try unplugging from PC and entering bootloader via keypress
Then see here
http://forum.xda-developers.com/showthread.php?t=2670400
Pay attention to the third post, you could also flash a custom recovery and sideload a ROM if you don't want stock
Best of luck!

Thanks for pointing to that guide. It worked and my N10 is back to live
Dear XDA friends,
i always hoped not to be one of those guys, who f****d up their phones to the point of no return. I really screwed up this time. Well, here I'am writing you about my screw up.
I unlocked, rooted, flashed and repaired all kinds of android phones in the past years, never without problems, but I could always fix it somehow. Not so much this time.
Now I'm stuck at Bootscreen with the Zuk logo. I even have problems pinging the phone via ADB.
Sorry for my noobish question guys. Any help would be much appreciated.

I got this translated from a chinese website:
For fastboot mode:
The phone turned off; keep the connection turned off the data cable to the computer, press: [volume down key] [Power Key] waiting to enter the fastboot mode.
For recovery:
Turn off the device
Press and hold Power key
When vibrates Volume UP key + Volume Down key about 10 seconds
Release all key when Android logo appear then you will see Android System Recovery
Use Volume key to select Menu
Use Power key to Confirm
Can you enter any of these 2 modes?

The bootloop is just showing the ''ZUK logo'' in the middle of screen and "'powered by Android logo'' below,and the phone vibrates everytime it flashes these logos. I tried QFIL but it can only detects the unit on the first boot or first flash that is 2 secs. only from the time i press the power button, and then it disconnects and not detect the unit again. Does anyone know where can i find the scatter file , MTK ROM for zuk z1, i would like to try the SP flasher tool. Or if anyone have any idea how to solve this issue on lenovo zuk z1,pls. help.tnx
Can y get to fastboot ?
im facing the same problem after i had the stupid idea to lock the bootloader again, before that i flashed the phone successfully with the cm mod recovery and cm 13.
Has anyone found a solution to this ? or do i have to send it back ?
What i did exactly :
I locked the bootloader again and just to test it i tried flashing the recovery again , ofcourse it didn't work which was what i wanted.
Afterwards i rebootet the bootloader with sudo fastboot -i 0x2b4c reboot
now im stuck in a bootloop that i cant even stop , in other words i cant turn my phone off nor can i access the recovery or fastboot
Im feeling so stupid that i locked it again .... i will try to get into recovery after my phone ran out of battery but so far it looks quite bad...does anyone know if i will get a replacement even though it was my fault ? ( i don't need to say that it was my fault ..and the bootloader is now locked again )
UPDATE::
I found a promising thread about this problem, i will report back here if i was successful.

Please help , same problem
I am facing same issue too from 2 days. I didnt even try to flash custom roms or play with boot loader or recovery or anything. All of a sudden my phone entered boot loop. After two three bootloops phone is entering "12 apps optimized of 230 apps" mode, completing optimizing all apps and then failing to start apps, entering boot loop again.
Effort made so far to fix -
1) Went to recovery and cleared cache - didnt work
2) Went to recovery and did factory reset - factory reset did happen but boot loop didnt stop, I realized that factory reset happened because now its saying optimizing 120 apps instead of my 230 apps during the bootloop.
3) Went to recovery, Entered fast boot mode but not able to connect to PC. Fastboot devices is not showing anything. I made sure proper driver is installed after researching on XDA.
4) Went to recovery, Tried "Install update". Didnt install anything but browsed through folder structure and realized my data is intact
It will be great if someone can help me atleast recover my data before I handover phone to service center for fixing boot loop issue.
Same problem

Sorry For Re-posting Here. This is Solution
Why this is happening ?
Due to Dirty Flash from Zui or from COS/CMOD but suddenly Bootloader gets locked
May be Due to Some Custom Rom which only works with Old Bootloader ( And you are on latest 2.5 Zui QPST Flash)
Reasons are many. I also did same mistake. I flashed ZUI 2.5 using QPST then unlock bootloader using official site installed twrp after wiping cache system and data , Installed Lineage 0S JAN Build then without rebooting installed Lineage Nightly build (Latest) with Gapps After rebooting Phone goes into Restart endless loop on ZUK Logo. Blink and Vibrate .. After 1hr I figured it out but its 5am So slept.
HOW TO FIX ENDLESS REBOOT ON ZUK Logo ?
-> Identity vibrate patterns (Press Power Key I count 6- 7 Vibration pattern ) After long Vibrate immediately remove finger from power key.
->Once its Done (Phone completely off)
Download QPST and Official COS QPST from this Link https://goo.gl/InWQji OR https://goo.gl/iqrnlI (I am personally Very Thankful to D tech Terminal for posting Wonderful video on Youtube https://www.youtube.com/watch?v=4Dl6JkAVpuM
<- please install all drivers and software.->) @ankurpandeyvns Thanks bro.
Main Task is here and Lots of Patience is required and You also need to be very Blazing fast to achieve this.
-Once you download and install Qpst open Qfil
-Now press Volume Up only and connect USB (Just press POWER KEY only for 1 sec It will vibrate and connect)
-Without waiting hit Download button.
-Voila It will start flashing your phone again and Hence Your phone is now Revive..
-Once Revive You can use it to again flash custom Rom or stick to stock Rom if you want.
Keep Flashing !!!
Patience is Key here. And Don't lose hope.
:good:
EDITED:
While connecting to pc and by pressing Volume key you also need to press Power key for 1 sec or 2 sec until it gets detected. Thanks addicted777 (for tip)

You can try factory resetting your phone.
Steps :
1) Power on or reboot your phone. Press and hold volume up+volume down button for 10 sec while your device switches on.
2) In the recovery mode, choose factory reset and follow the instructions.
Now your device will be completely factory retested and no more lock.
Same issue
Okay so I'm in a bit of a bind, I've been running NSS 6.5 for many months and today I decided to factory reset my phone so I can hand it over to my son. Without thinking, I factory reset from the settings menu and it took me to recovery mode. I immediately tried rebooting the system only to be forced back into recovery. I factory reset from recovery and rebooted and was forced back into recovery. I reflashed the ROM at that point, and rebooted and was forced back into recovery. I'm in a real bind here and I haven't been able to figure out how to get out of this from searching around. I'm really hoping somebody can come through for me here, I would really appreciate the help! Thank you!

Turn off the phone completely. Power on while holding volume and power. Once the lg logo shows let go of the power and press it back down. It should give you the factory reset option. Select yes yes (it won't format just take you to twrp. Once you're in twrp press system (I think that's what it's called - bottom right option). Then select reboot.
