boot loop after lineage os installation - G2 Q&A, Help & Troubleshooting

hello everyone,
I just installed the lineage os, but it gets stuck at the boot animation, can you help me accessing the recovery? It doesn't let me do it by presing the volume down and power button like I used to do.
Please help me, I can't use the phone and it is the only one I've got
thank you

Go through the link below, if you can't find what you need ask again on the link below, and add detail for what version of stock firmware you were on, lollipop is preferred, what version of TWRP you are on, the latest is 3.1.0-0, and if you took the lineage OTA update, OTA is currently causing bootloops to TWRP (read posts before and after post 777.
Don't do anything to partitions from the terminal without backing the partition up first.
There is also a lot of info in the thread, use the thread search function.
For LG D802

[Q] Installed another tablets rom on my acer a500

i accidentally installed a rom that is not for my tablet...now when i turn it on it stays vibrating and nothing appears on the screen...pliz can someone help?
can you boot into recovery? i believe its vol down + power
If you can't get to recovery its time to go to Acer....
If it vibrate's all time then I think then installed that tablet bootloader.bin, if you want to recover your tab you need download EUU HC 3.2.1 rooted version from http://forum.xda-developers.com/showthread.php?t=1307539
And read instructions how to install it. Sorry for bad English.
ive tryed getting in recovery mode and even ractory reset but nothing happens
Do you know how to boot into APX mode?
hope this help

I HOPE, before you did this silly "accidental" thing, that you did a recovery backup before you commited to this act? Because you will probably need your original UID number. And you can find it in your recovery files on your ext sd card.

It ain't over, till the big hog sings..... (I hear squealing though)
Actually, if you can get into APX mode, and you have your original UID number, the chances are 70/30 for recovery.

I had a couple of spontaneous reboots at start, but other than that this is really smooth and I haven't found any major bugs. I'm running d802. Just beware that you can't access recovery with the vol down + power, but doing reboot recovery from adb works. And for some reason viper4android does not work.

Yes you can still access recovery, but in a different way.
Just press vol down + power as usual when power is off and then press vol down + vol up after the LG logo is shown.

how can i solve your same problem????? thanks so much
It would be awesome if you could upload the 1.1 version to Google Drive or sth. cause the Filehoster you posted is crap. Thanks
All it's ok for me. Great rom.
Best way to go to recovery is installing ROM MANAGER or similar.
So in updated my bootloader to the KK one to get the rom working. Now everything seemed great, except I was not able to get into recovery. Someone (not sure who) said i should use AutoRec, and so i did. But now i'm stuck with a secure boot error. Download mode still works, so not all is lost, but i just wanted to know if there is an easy fix for this, or at least a way to save some of the files on my phone. Thanks.
Warning to all D801 (T-Mobile) users
Wifi does not connect, mobile data only works sometimes then disappears. Do not flash if you are a D801 or you will have this issue, hopefully there is a workaround to this but I am yet to find one.
Abseloutly stunning, even tho this rom is a mess when installing, but if you got it right, you won't dissapointed, i can guarantee it, btw I'm on VS980, thanks for brint it here. good job OP.

Recovery works fine, this ROM doesn't have an option for advance boot though, so if you want to go into recovery/custom recovery, it's just the same method with pressing this combo:
But first make sure your phone is turned off, then Press and hold Power Button + Volume Down Button, after the LG logo shows up release ONLY Power Button and quickly press and hold Power Button again.
with this combo you will go into LG default Hard reset page, but don't worry it's NOT! , to go to recovery page choose Yes and another Yes, and viola!!
hope this help

WARNING!!! for rom_simple_5.0.1_v1.1 the zip package from Fshare link contains an error for:
var\d800\modem_d800.img. i got the message from winrar that "The file is corrupt"

It is a great shame that I find this thread late on a Sunday, so I am not very keen to experiment right now. But have two burning questions for my d802
1) will it skype?
2) are there any options for kernel control?
And yes I have read the entire thread.(before those people start)

Lol and how do you flash stock on bootloop ? Read OP then comment .....
If it is caused by chainfire bootloop, and can not enter the recovery is the only alternative, only come into download mode

Op is asking how to get out of bootloop and access any menu so he can install things like stock you mentioned
You basically told him what he wants to do anyway and not how to do it ...
One does not simply plug bootloop to PC and flash ....

Get your stock firmware from sammobile.com (sorry to the Mods for linking a page where you have to register) and flash it through Odin
---------- Post added at 07:00 PM ---------- Previous post was at 06:59 PM ----------
Or you could flash TWRP (http://forum.xda-developers.com/android/software/twrp-twrp-galaxy-core-plus-sm-g350-t3275740) through Odin and restore a Backup of the stock rom (http://forum.xda-developers.com/gal...-nandroid-backup-twrp-stock-4-2-2-sm-t3316010)
ATTENTION: Make sure to only restore /system

Download your stock system from sammobile.com and flash it through ODIN. Your files on the internal memory may disappear when doing this.
If it doesn't work afterwards, try the same again with an attached PIT file for the phone:

WARNING: Flashing with an attached .pit file will format your phone. Do it with caution!

Try qfil method, between the reboots there is a chance your device gets recognized. Before that: empty your battery completely(otg) and check if bootloop is gone

Even I have the same problem.
I locked The bootloader after installing cm13, and the phone went to bootloop, now I cannot unlock my phone. Somehow I went to fastboot mode and tried all the commands to unlock the phone. And the phone responded "Access denied".
Tried with qfil also and it didn't work. Some or the other error. My phone is dead, someone please help me..
Try this..
Remove battery belt,
To switch off your phone.
Then attach it again,
Keep pressing UP volume button while your phone is off and attach USB.
As your computer detect Qualcomm Port, click on DOWNLOAD button in QFIL & install stock firmware again.
Try at your own risk.
Been there.. Had the same issue..
Exactly the same.. Flashed zui, then mokee and boom.
Unstoppable boot loop. Just zuk logo followed by a small vibration and restart.
I am giving you the solution.
1. Let the battery die. It will take 7,8 hours.
---------- Post added at 04:58 PM ---------- Previous post was at 04:53 PM ----------
2. Download these-
a. Tool all in one
b. Fastboot drivers
c. Lenovo/zuk drivers
d. Pc
e. Twrp 3.0.2(flashable img format)
f. Rom and gapps (download them afterwards only if rom isnt present, You will know it after the process.)
---------- Post added at 05:03 PM ---------- Previous post was at 04:58 PM ----------
Steps.
1. Let the phone die.
Press power button when it stops - this will start the whole bootloop process again.
Do this till there is just a 2 min loop mode ie. It loops for just 2 min,then goes off.
*power + any key combination doesnt work. No twrp and no fastboot mode.
*pressing power button for 30 second to switch off the phone doesnt work.
2. Install all softwares.
---------- Post added at 05:16 PM ---------- Previous post was at 05:03 PM ----------
3. Press vol up and down both and connect usb from pc. It goes to fastboot mode.
*dont remember exactly if it was vol up + vol down OR vol up+ vol down + power. Try both please.
4. See if phone shows up in connected fastboot devices. If not, do this-
a. Remove phone. Check driver status of pc.
b. Retry if all seems right.
5. It connects in fastboot mode.
6. Now let me tell you the basic problem - you have a relocked bootloader courtesy zui.
So, you will have to unlock it again.
*full data gets wiped due to this process. Your internal memory is formatted.
7. Check bootloader status. If its locked, unlock it. Then, flash twrp again.
*flashing twrp isn't compulsory, but we are doing it as an added safety check.
8. If it isn't locked, you are lucky, just flash twrp again.
9. Reboot to recovery from tool all in one.
10. If successful, reboot to system from twrp. If your previous rom is present and it boots up, its great.
Otherwise, you would have a zuk logo that doesn't restart, it stays there continously. Press power button for 30 second to switch off the phone. Download rom and gapps and flash them via external usb through twrp.
---------- Post added at 05:20 PM ---------- Previous post was at 05:16 PM ----------
11. If this fails,there is a method called qfil (as stated by @strongst).
There is also a youtube video for qfil method. Channel is dtech terminal, watch it to see how its done. It also has the links to all files for qfil.
*I am in no way related to dtech terminal. Sorry moderators if i am violating any policy by giving link kf ylutube channel.
I'm in the same situation and found solution as below link
