[Z00LD] Big Problem - LineageOS Update softbricked my phone - Zenfone 2 Laser Q&A, Help & Troubleshooting

Hey, so here follows my problem:
I downloaded Lineage 0707 and the latest Gapps, installed both.
started installing my apps when a popup came in saying there was a new version for me to update into, for some reason it said it was version 0707.
I was like "Sure, another update, lets install it" and hit the install buttom.
Now the cellphone will only go into recovery mode, not even when I reinstall LineageOS it boots into SO, and I am completely lost since this never happened before.

but you have a working smartphone without installed OS. Just instal some custom rom or go back to stock rom. What is the problem? Instructions for going back to stock there is on the official website also here in xda

N910F problems - emmc read fail/ flashing stock no longer boots the phone.

Hello. I had gotten this Note 4 phone which had a custom recovery installed on it but the rom seemed to be official, on 5.1
The first thing I did was go to samfirmware and flash a 6.0.1 rom, it went fine, phone was working properly. Then I got greedy and wanted to test a Note 7 ported rom. Flashed TWRP recovery and from within I flashed RamROM http://forum.xda-developers.com/note-4/snapdragon-dev/rom-sm-n910g-ramrom-t3400349 , I downloaded the one from post#2 , the N910F one that my phone is and after it flashed to ROM it simply stopped working. My phone no longer booted, was booting me directly into Download mode with emmc read error. I kept trying to flash the stock rom which I previously flashed and it would fail.
Afterwords I used Smart Switch to reinitialize the phone, writing my phones S/N and that failed as well but at least that made my phone boot into a different recovery where it said to connect to Kies. Once again I used Smart Switch and this time it was successful 100%. My phone even booted into the OS and was working, however, while using it, after 10 minutes the phone restarted into Download mode with emmc read error.
So all in all the phone is functional but it starts to lag and restart. Now I'm kinda stuck again since I've tried to flash the firmware I got from Samfirmware through Odin, it succeded but it just doesn't boot, it goes to Recovery, tries to apply an update and I get an error.
Is there anything I can do? I can't believe the emmc could've broken just from trying to flash that custom rom, especially that afterwards I was even able to boot into the phone.
Thanks for reading and I appreciate the help.

read this - http://forum.xda-developers.com/note-4/help/note-4-issues-t3453048
there are links to more threads related to your issue.
Short version though:
it is dying. install wake lock application, add it to start up and set settings to #4.
accept the fact that your phone will eat the battery faster and one day WILL die completely
Thanks for your response. Regarding the Wake lock application, I'm starting to look into it, I asume I'll have to be rooted. I'll try to recover it again using Smart Switch and then I can only hope I can install TWRP and still have it functional.
Previously when I was able to get it working with Smart Switch, entering the recovery messed everything up. It said it was applying an update and that got stuck.

no need to be rooted, just download, install and set it to autostart
I'll try it if I somehow manage to get the phone working again, Smart Switch just fails now midway through.

Is this the app you're talking about? https://play.google.com/store/apps/details?id=eu.thedarken.wl&hl=en
What exactly does it do?
I managed to restore it eventually with Smart Switch, it took quite a few tries, then I switched to my Macbook when I saw the app was available on it too and the 3rd try succeded. I only did it because I saw the 2nd try had the % much higher than the first.

yes, that is the app.
i've read it does not allow your phone to go to sleep mode.
drains the battery faster, but this is the only way to keep note 4 working without swapping its motherboard...
I have a question, my gf recently bought a note 4 and we may swap our phones and if we do, i'll flash CM and tinker with it because i find this phone very interesting, just a question, does this bug affect the N910C (exynos) model? Do i have something to worry about? Because the phone is warrianty protected and if it's the case, i don't want to break it. I hope someone will shed some light on this

7.0 Update Crashed my Device. Custom Roms won't take. Stock Rom crashes, too

I received an update push from Motorolla that installed Nougat. After that, my phone would crash every 3-10 minutes. I did all the troubleshooting I could find online. I contacted support and they wanted me to spend $150 to get it "refurbished." Of course, it sure seems like a software problem, so that wouldn't help me anyways...
I turned to custom. After rooting, installing SuperSU and TWRP, I couldn't get several versions of AICP or Lineage to ever boot (stuck on loading screens). I also tried all the advice from this thread.
I went back and installed the stock Rom using f2fs , and the phone would get to the "hello moto" part of the boot up, then crash and reboot. I tried again using EXT4, and it worked, but just like before I ever begun, my phone was crashing every 3-10 minutes. However, the first crash wasn't until after I made a phone call, and my phone had been crash free for about 20 minutes before that call.
I'm a I.T. guy, but I'm not a "phone" guy. But it seems to me that there must be some other software that was modified during the update that is causing the problems that isn't part of ROMs. Something in the Kernal, or a driver folder or something?
Also, is there a way to get crash reports? So maybe if I at least go back to the default ROM and wait for it to crash, I have some info to work with?
Any help is greatly appreciated, thanks!
Flash full stock 6.0x for your model/region.
Important:
Without bootloader, gpt. Don't try locking BL.
Links you can find in my signature.
Try normal boot and after success any custom.
You cannot allow any ota update after it.
Some customs are only for Nougat modem/radio - don't flash it. @Kaivian
Ok, I got most of that, except I don't know what gpt refers to and am not getting any hits on search.
My signature - flashing stock - without bootloader & gpt.
So, I installed a 6.0 stock ROM and got tons of errors. I tried a 2nd time, still got tons of errors. Needless to say, stock 6.0 didn't boot. I decided, "The heck with it" and tried installing Lineage 7.1 again... and it worked! It finally booted up entirely. However, now I get a "Sim card missing" notification. Can I just reinstall part of something... like the modem? so I can keep this "working" lineage boot? Or am I starting over yet again?

This caused it to not boot.
I went back to 6.0 and turned off auto-updates. I'll try again sometime when I have time. I did like the custom rom a lot, just couldn't use it as a phone xD

I am having problems flashing stock rom and locking bootloader

So basically, few months ago i tried to root the phone, get new recovery and different rom. If I remember correctly I got stuck trying to get custom recovery to work, because everytime I restarted phone it would be replaced by the stock one. So I left the phone as it was, and disabled the TWRP app on it. Problem was, I could not update phone. Today I tried to completely revert to stock.
I flashed stock recovery but when I tried to install update from the phone storage, it did not even give me option to select a file.
I tried to update the recovery to newer one which gave me the option to select a file, but the installation got canceled after few seconds, putting me back on the file selection screen in recovery.
I tried to instal TWRP but I can't even boot into it at all because the phone is just stuck with blackscreen and lightblue led light.
I tried to ADB sideload the newest stock rom that I downloaded from OP5 site but this one went to around 50% and then crashed as well.
I also tried to do the update using the Settings>System update > Local Upgrade but this one also fails once it gets into recovery.
I tried wiping cache/reset system settings or wiping every data on the phone before any update but none of it seems to help and everytime I restart the phone afterwards the TWRP app is still there needing an update.
I tried to just lock the bootloader but I got the "Your device is corrupt. It can't be trusted and will not boot" message followed by link to google support. I assume that is because of the TWRP app that is on the phone but I can't get rid of it no matter what I try. I tried searching for people having simillar problems but I couldn't find anything that would help me.
Any suggestions?
Thanks in advance.
You can go with the last resort and use the Unbrick tool.

Unable to flash RN7

Hello everyone xda users / developers. I got one problem. I sat on the MiRoom firmware. After that, I wanted to install EvoX. Before installation, I made a backup of MiRoom so that if something comes back to it. Everything worked well. And I decided to return to MiRoom. So I installed backup and rebooted smart. I noticed that the phone was loading for a long time. But the phone turned on. But I could not unlock it. I installed a script that removes the lock password. Everything worked fine but there were bugs. And after that I decided to return to Official Rom Stable. But I could not install it. Since the phone was not detected in Fastboot. The problem is that I can’t even go into Recovery because the smartphone hangs on the Redmi splash screen. I decided to install the firmware via EDL but could not. Since I get the error Only nop and sig tag can be recevied before authentication. How to solve this problem? And is there any way to solve this problem?

Need help installing Lineage OS 18.1

Hi!
(Note: Please skip to the third paragraph if you don't want to read my entire useless lifestory lol)
So... Around September-ish 2022 I got an S5 Neo that was previously owned by a good friend of mine, she gave it to me because she didn't need it anymore and I was stuck without a phone for a while because my daily (iPhone 6S) was tragically killed after I accidently dropped in the sea.
Anyways, the S5 Neo I got had Lineage OS 18.1 (Android 11) on it and it was really nice to use thanks to how light that ROM was, fast forward to January 2023 and I got a new phone to replace the dead 6S of mine and the stopgap S5 Neo, but I decided to still use the S5 Neo every now and then as a secondary phone or a testing phone, for custom ROM's, recoveries, and that kind of fun stuff. I successfully installed the latest stock software it supported and tried a few things I wanted to try, like the camera for example, I wanted to see if the camera would be better on the stock Android compared to Lineage OS, etc.
But after I installed the stock software for the S5 Neo I was unable to revert back to LineageOS due to my lack of knowledge with how this all works, I assume I got the "revert to original software" part right because it's a simple "Download Odin, download the software for your phone, put it in download mode, boom it's done", but every time I tried it with LineageOS it doesn't want to work.
My main issue is trying to install TWRP or Lineage Recovery using Odin, I tried to be fast, tried the remove battery trick, the hold power button for 10 seconds then hold buttons for recovery when out of download mode, I tried everything, can someome please help?
The problem I am facing is that when I hold the buttons to go into recovery when it's in download mode when the recovery is successfully loaded, it doesn't go into recovery, and when I remove the battery and install it again and press buttons to go to recovery (A guide I read said that) it just got stuck on the flashscreen forever (Not bootloop, just "Samsung Galaxy S5 Neo" flashscreen stuck), and only got unstuck when I removed the battery again or went into download mode and said no, restarting the device, and at which point I think I have the original OS still but actually funnily enough no recovery whatsoever, not the normal one or the TWRP recovery, so yeah I really need help
I am open to any suggestions for methods that are simpler for a noob to me to go through to install a custom ROM, my goal is to install LineageOS, not to install TWRP. Thanks!!!

I would just follow the official installation instructions. Read through them once before you follow them and you should be fine. Let me know if you have any questions regarding flashing it (Don't worry, I remember my first flashing ).
