Help in flashing custom roms - Zenfone 2 Laser Q&A, Help & Troubleshooting

I've unlocked the bootloader using the official asus unlocking app.
Upon checking fastboot oem device-info it says that my device is unlocked.
I had flashed twrp 3.0.24 using fastboot and rooted it but when i try to flash cm13 (downloaded fom official cm site), it gives error 7.
So, I had removed asserts from updater-scripts and tried to flash which was successful but it did not but and got stuck at fastboot mode
I had anandroid backup which helped me reviving and after that i eve n tried ressurection remix, which too fell me in the same problems..at first i got error 7 and after removing, it didnt boot..
I even flashed cyanogen recovery but after flashing, when i try to boot into recovery, it gets stuck at the fastboot mode ... though it booted normally, but it didnt boot into recovery mode.. so i again flashed twrp which booted properly though..

Nexus won't boot properly after flash

Hey guys, I flashed SmoothRom via that app goo.im, and when I did it, it said that I needed a compatible recovery, so I flashed the one that it recomended. Well I flashed the rom, and now my Tablet won't boot properly. I can get it to fastboot, but even when I try to flash a recovery from fastboot, it gets stuck at the boot screen (Yes my bootloader is unlocked). I've been trying to use the Nexus 7 toolkit to flash the recovery,and it is saying that it is flashing successfully, but I still cannot boot into recovery. Any ideas? I know I'm not totally bricked cause I can still get into fastboot, I just need recovery to work so that I can flash a new rom and fix this issue!
Fixed it! Just flashed the stock recovery, wen't back into fastboot and flashed CWM. Mod's you can delete this thread now

[SOLVED] Recovery loop - Bricked? - Reboot Mode Flag: Recovery

Hello everyone,
I'm not new to flashing and ROMs, so I tried flashing the Android L AOSP build from here. I succeded and wanted to install gapps through TWRP. I don't exactly know what I did. Now when I power on my device, I always get stuck in recovery. I already reflashed the 4.4 factory image and the AOSP lollipop build serveral times, but my fastboot info still says "Reboot Mode Flag: Recovery".
Summary: Fastboot works, I can flash imgs. Every time I start/restart it reboots to recovery.
I also tried relocking and unlocking, but I had no luck.
I hope I get my Nexus 10 working again.

How did you flash the android 5.0 zip ?
Thx Josh
I extracted the imgs from the zip and fastboot flashed them one by one. Then I flashed twrp (the stock recovery didn't work seither), rebooted to twrp and installed pa pico gapps with modified script. When I rebooted, that worked. I booted to recovery a few times to make the Google Now Launcher a system app. Since that it is only rebooting to recovery.
I doubt that it's bricked.
Have you tried flashing the factory image KTU84P exactly like instructed here? :
https://developers.google.com/android/nexus/images
Nope I already tried that..
once when i was upgrading from 4.3 to 4.4 i experienced something very similar. nothing worked.
the way i fixed it was to relock and then unlock the bootloader (even though it appeared unlocked, something was wrong.) I hope this helps.
I finally got it working. Thanks for the time you spent helping anyway.. So I flashed CWM through fastboot and restarted to recovery. CWM cleared the boot flag properly, which TWRP didn't. Now booting

Issue with unlocked bootloader

Hey,
I had AOSP rom and i decided to go back to OOS. (xXx rom)
I entered TWRP, Cleaned Data,Cache,Dalvik,System.
And Factory reseted it.
Installed the xXx rom, and i got on the splash screen instead of "Bootloader Unlocked"
And i'm getting "<!>"
And i couldn't boot.
And i can't press volume keys to get to recovery or bootloader, but it boots straight to bootloader.
i entered to TWRP again (Via bootloader), reflashed stock OOS.
It booted, and then i entered bootloader to flash TWRP again, and it didn't succeeded
I enter only Stock Recovery and every time i try to flash Recovery it's succeed but it's does nothing, still entering Stock OOS recovery.
Now i stuck at stock OOS, and stock rocevery.
Can't flash anything.
Can someone tell me what to do?
Best is via ADB flashing latest BlueSpark TWRP (fastboot devices, fastboot flash recovery (name of TWRP).img and then format all so you start with a clean plate. Then move your ROM from PC to Internal and proceed further. But IMO a "format" is needed. Also siakantabg made a flashable zip from the old bootloader. Flash this zip in TWRP first after formatting en wiping everything.

Stuck in black screen, can't boot into fastboot mode

I got my Mi A1 today and it came with Android 7 installed, so I decided to install LOS. I unlocked the bootloader and then I booted into TWRP using fastboot (I didn't flash it), it gave that "system is read-only" warning. I tried to reboot to system without doing anything and it was stuck in a boot loop. Then I booted into TWRP again and flashed LOS sucessfully. When I tried to flash gapps, however, it failed claiming I was still running Android 7. I rebooted and it booted sucessfully into LOS, but that was the last time the phone ever booted. Now it shows the unlocked bootloader message and then gets stuck in a blinking black screen. I can't even boot into recovery or fastboot anymore.

It seems you will have to flash stock ROM using Mi Flash (no idea how to use it so search it) and, once is done, flash LOS again.

I somehow managed to get to fastboot and then I used MiFlash to flash the stock rom. I'm back to the bootloop, which is an improvement, because at least I can consistently get into recovery and fastboot.
The phone got stuck in that black screen after I tried to flash LOS, should I actually do it again?
EDIT: I flashed the stock rom a second time and it's working again. I don't know why, but I'll take it.

Update to stock Pie before trying to reinstall LOS again. Hope this time works.

You should install 1.0.8.0firmware first before install 9 ROM!?

-PLEASE HELP- UNABLE TO FLASH TWRP OR ROOT

Hello
Sorry for my bad english
a few months ago, i decided to flash my first custom rom (One UI rom) and it worked fine
then i was testing a lot of other roms too until i tried lineage os 20
when i flashed lineage os 20, i decided to try another rom but i was stuck on the twrp logo screen. i tried methods of fixing it but none of them worked.
after trying a method of flashing twrp once again, it failed and i got stuck in a reboot loop and could only boot into download mode. so i booted into download mode and flashed a stock rom.
everything was working fine again until i wanted to try another custom rom. At first whenever i would flash twrp, they would always fail. but later i found the cause of that and fixed it. then, flashing twrp would always pass but my device would get stuck on a reboot loop once again and i had to flash stock rom again.
i tried rooting using auto root but it would show me a verification failed error and i had to reset my device. so now im stuck on a device which cannot flash twrp, nor can it be rooted. its been 1 month and i could not find a viable solution so any help would be extremely appreciated.
You have to just reflash your fastboot rom with fastboot mode unzip it and double click on flash_all.bat file or something like that
it is a samsung, there is no fastboot mode
