Fastboot Mode - Zenfone 2 Laser Q&A, Help & Troubleshooting

Hey Guys I Installed lineage OS 14.1 on ZF2 Laser ZE550KL Z00L
Everything was normal...But when i clicked reboot system after installation it went straight to fast boot mode.
I can boot into recovery just fine but i cant enter system
Need Help Thanks.

Might be a boot problem. Try reflashing the kernel inside the rom.zip manually via twrp img flash mode.

help! not sure if i hard bricked my phone

Hi everyone i flashed kings marshmallow hydrogen os but i didnt like it so i reverted back to my blisspop via nandroid backup. Unfortunately I am know stuck at the oneplus boot screen with the oneplus logo in the middle and the powered by android logo at the bottom. I am unable to boot into twrp. I was able to boot into fastboot mode and managed to flash twrp recovery however the phone will not load into recovery and goes to the oneplus boot screen. I think i softbriked or hard bricked phone because i went from kings hydrogen os which is marshamllow based to my nandroid backup which is blisspop 5.1. IDK what to do know
Bottom line i can boot into fastboot mode. device manager on my pc recognizes phone as android device- marshall london bootlooder interface any suggestions?
If you can Boot to Fastboot you have a softbrick. Somewhere around here is a thread for the recovery tool with the qualcom drivers. Read carefully and maybe give it a try.

Stucking 1+ logo is because having unsupported recovery from system... After you did restore did you got any error...
Get both recoveries and try command
fastboot boot recoveryname.img
One of them has to boot. Youre doing something wrong

Lost recovery, cant boot, only fastboot

Guys... when i tried to flash oos 3.0 on my op2 through twrp, i first wiped the data to install new rom, then install oos 3.0, it failed. I then flashed the recovery i downloaded from the thread, then restart the recovery
I cant boot into the recovery.
System can't boot
Is it called "brick"?
So i tried to flash stock recovery in pc by command, but it says "remote: device is locked. cannot flash images". any solution to this problem?
I can boot into fastboot mode
You need to run the phone in Qualcomm mode on a PC and run the recovery tool to fix you bootloader.
I did the same and it was a royal ball ache trying to find out how to fix it
Don't do what rosswaa said
Why not?
What you should do is boot your phone into fastboot mode, connect it to your pc. Flash this modified TWRP recovery img to your phone https://www.androidfilehost.com/?fid=24459283995297945. After that you have to flash this modified SuperSU (through the new recovery) https://www.androidfilehost.com/?fid=24459283995297946.
The normal recovery doesn't work in OOS 3.0 (just like in HOS) and it's the SuperSU that gives you the soft brick. A dirty flash of the modified SuperSU should fix it.
I also had your problem and I did what rosswaa said which shouldn't be necessary (I lost all my data and backups).
I didn't lose anything, but I tried doing what you said and my bootloader was screwed so wouldn't take a flashed recovery or anything (yes the modified one)
Wish I hadnt been so excited and just flashed but all sorted now
Hmm okay, if it doesn't work with flashing the new recovery img then do what rosswaa said and after that follow this post https://forums.oneplus.net/threads/installation-instructions-faqs-oxygenos-3-0-0.439108/
Obviously try what green says first, if it works then happy days
first i am really glad that someone give some advices on me. But since i am a noob, how can i flash twrp in fastboot mode? using command? "fastboot flash recovery xxx.img"? thx

Error loading zip and img on twrp

Hi guys. I have a problem with my ze500KL. I can install only the twrp 2.8.7.7 version. But when i try to install img or zip of roms /original firmware, the twrp fails the operation , saying " error data", "unable to mount"... i have problems with wipe too. any solution?

I can't understand what you mean. If you want to install stock rom from TWRP recovery, you have to modify updater-skript.
Why do you can install only the twrp recovery 2.8.7.7, when we have the twrp recovery 3.0.0.2
File img you can flash from fastboot mode. Commands:
fastboot flash system file.img
fastboot flash recovery file.img
fastboot flash boot file.img
or
fastboot boot file.img for example twrp recovery img or stock recovery img. This is command for once booting.
I want to return to original firmware , i download it from the site of asus. So, i booted twrp in fastboot mode (i tried different version of twrp, but the only that starts is the 2.8.7.7 version) using adb.
Now i am in recovery with twrp 2.8.7.7. I can push using .zip files or img files on internal storage.
But i have different problems with this recovery:
IF i use wipe function: error opening sys, could not mount, enabe to mount, ... (failed)
If i install rom or firmware with zip files: error unable to mount, unable to find partition for path.... (failed)
Adb sideload goes failed too.
What should i do???
I think that the problem is in the internal partition... I have to install using a min usb ext storage? or what????? thanks :fingers-crossed:

Easiest way to fix your phone is flash stock rom from stock recovery. Stock rom put to sd card. Reboot to stock recovery and choose flash rom from sd card. New version number system must be the same or higher than installed in the phone.
Do you want to return to the lower version of Android.

Stock recovery doesn't work man. The only recovery that works is the twrp 2.8.7.7. But it has problems.

Do you have Lollipop or Marshmallow and what is your version number.
For Marshmallow you need to this working twrp recovery.
https://drive.google.com/file/d/0B7F3ZXr565GkY28yUjhfRkd5MUk/view?usp=drivesdk
For Lollipop you need to this working twrp recovery.
https://drive.google.com/file/d/0B7F3ZXr565GkY1NQbUtoVzdwWEU/view?usp=drivesdk
If you haven't installed stock recovery, it's not no problem. You can it flash from fastboot mode.
i had mawshmallow. i tried but failed...

How did you flash the file twrp.img.
OK guys I've solved the problem. I moved in this way:
1) Volume up + power to go in fastboot mode
2) after installing adb and the other drivers, i've insered these commands:
fastboot erase cache
fastboot erase userdata
fastboot erase system
3) after downloading twrp version 3.0.0 (for the zenfone 2 laser), I load it using the command "fastboot boot (name file twrp).zip"
4) the recovery starts automatically. Now i downloaded the file "back2stock.zip" and the original firmware (WW, worldwide) form the official site of the Asus
5) this passage is the most important:using 7zip I've extracted the file zip of the firmware and the backtostock, then i created a new file using 7zip : in this new zip i've loaded the files inside back2stock and the files file_contentexts, system.new.dat, system.patch.dat, boot.img e system.trasfer.list inside the zip of the official firmware
6) I've loaded this new file on the phone using the command "adb push (new file name).zip /"
7) at last i have installed this file on the phone ENJOY it

Failed Update from 10.3.12 to 11 - Assistance Appreciated

Attempted to update from the latest stable 10.3.12 to 11 by flashing the full OTA zip in TWRP.
Install failed and phone locked up.
Attempting to boot to recovery or system results in Qualcomm Crashdump Mode.
I can get to Fastboot, but I'm not sure if I should try flashing twrp.img or pull boot.img from the OTA or what.
Anyone have any suggestions?

I did not have time to wait so before bed I just reset everything.
I ended up using the MSM tool located here:
The Complete Guide to Unbrick OnePlus 6/6T from a Hard-Brick using MSMDownload Tool
Unlocked bootloader, installed TWRP & Magisk, installed A11 zip, everything is working again now.
Good luck!

Flash temporary recovery first ( lineage recovery ) then from fastboot.. boot into recovery.
You will see lineage recovery.
Select apply update - > update from adb ....
Then "adb sideload <twrp image>.img...
(probably it ask to verify choose yes)
Go back select advanced restart ( not sure the right word ) -> reboot to recovery.
Then you will have twrp installed.
If you only want to root why not flash magiskpatched image there no need TWRP just to root.

Hm but how would I install lineage recovery? Flashing recovery through fastboot doesn't work on the new devices anymore right?
I also tried booting lineage recovery without flashing but that also didn't work (although it didn't get stuck on crashdump but booted into the regular OS instead).
I did notice that it seems to be related to OOS 11 firmware. On 10 booting into TWRP works just fine and as soon as I upgrade to 11 it stops working (maybe this means it's fixable?). What I used as a workaround for now is to have 10 firmware in one slot, upgrade other slot to 11 and flash TWRP to both slots from the 10 slot. Seems to work so far but is not ideal IMO. I'm not a developer sadly but maybe someone smarter than me will come up with a solution.
What do you mean by "new device"?? New OOS version right??
I use this method all the time with oos 11.x.x.x.x to install TWRP so i can install Custom ROM later.
no need to go to oos 10 you can flash it from newest oos11.
---------------------------------------------------------------------------------------------------------------
First boot into fastboot mode.
to install lineage recovery
fastboot flash boot <lineage recovery image>.img
download from here https://download.lineageos.org/fajita
menualy select and boot to recovery. It will boot to lineage recovery.

All Custom ROM installations fail the same way.

I am trying to get a custon ROM to work on my Oneplus 8 Pro (instantnoodlep)
ROMs I tried installing:
Cherish OS 3.9.5
Nameless-AOSP_instantnoodlep-12.1-20220708-0935-Official
What I do:
1. Download recovery provided with the ROM
2. Reboot to bootloader and flash recovery
'fastboot flash recovery recovery.img'
'fastboot reboot recovery'
3. Select apply update/apply from ADB
4. Connect device to PC
5. Sideload rom.zip
'adb sideload rom.zip'
6 Do Factory reset/format data from recovery
7. Restart to system
What happens:
Phone goes to fastboot and stays there.
When I try
fastboot reboot system
or
fastboot reboot recovery
I also land in fastboot again.
The only way to get out of fastboot again is fastboot boot recovery.img, which boots into recovery. When I then reboot into system, my old OOS11 boots up.
Because this is independent of the Custon ROM, there might be another issue. But which one?
You made sure you have latest OOS11 on BOTH slots?

When you're booted in OOS 11 just do a local install of the same OOS version that you're on. That will install OOS to the other slot, meaning you'll have the same OOS version on both slots and "should" be able to flash a custom rom.

U don't need the command fastboot reboot recovery. U can just use the volume buttons to select recovery and press power button to boot to recovery

Another way to set your phone up for a custom rom can be found here. https://wiki.lineageos.org/devices/instantnoodlep/install
Just make sure your booting from a good 00S11 install when you do this.
I had a heck of a time with this two days ago. OP pushed c33, A12 on my phone. It took forever to corrupt both a and b enough to get twrp recovery installed and working to install A11 again. I had to load the recovery on both slots, a and b and I used twrp install to install the OTA to slot a. Right now I have nothing on slot b other that twrp recovery.
