Please help me understand my options. I bricked my Zenfone 2 - ZenFone 2 Q&A, Help & Troubleshooting

I'm seriously stressed from thrawling through forums making posts and as of yet I've got no answers, hopefully someone here can help me or discuss my problems.
Yesterday I tried rooting the ZF2 Z00A , Originally a CN 2.20.40.63. It went into bootloop.
At this point ADB does not recognize the phone but fastboot does.
I tried installing a non rooted rom via SD Card but I got a signature verification error.
Now it looks like my only option is to flash a pre-rooted rom via Fastboot as that still recognizes the device. However I cannot find a CN 2.20.40.63 or newer pre rooted rom, I can only find CN 2.20.40.61 ....... am I right in believing that this would not work due to .61 being older than .63? Would it matter if I flashed a WW rom that was .63 or later? Even if it meant the phone was buggy but then allowed me to unroot and install a stock rom I wouldn't mind, I just would like my phone to work again (I only rooted because there was random webpages and apps opening and downloading the whole time).
Please somebody help. Also my brother who is in another country has a rooted CN 2.20.40.63 phone, is there anything he can do?

Have you unlocked your bootloader ?
No not too sure how to do that. Any good threads you guys reccomend.
Many thanks
So I know this is scary for you and because it is something new, therefore be sure that you want to live with the responsability if something goes wrong.
Now, the next forum thread tells you how to flash an already rooted image BUT, and this is very important, this works only if you have the version 10c installed (Check in About Phone>Software Version)
http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765
If you have the latest version of the software (20a) the best thing is to unlock your bootloader, void your warranty in the process, and flash a custom recovery. After that, you just need to flash the SuperSu zip file and you will have root.
To flash custom ROMs, just access recovery and flash the zip file of your ROM.
I'm using the unofficial CM13.0 and works very good for me, but I do miss the official camera app.
Thankyou very much for your advice okarr. Will look into this

Weird ZenFone 2 model?

Due to a series of unfortunate events(user error), I just purchased my third ZenFone 2. Each time I have purchased the same model Z3560, simply with different color and capacity just due to the pricing at each time. I just received the third one and I have found some oddities with it that I just want to share or ask about. I noticed on the gsmarena page that it says that the Z3560 is supposed to have 2GB of RAM but mine has 4GB. Also as I would usually do with a new phone, I went to update it but there is no update button where it was on the previous two ZenFone 2s I have owned, I simply cannot work out where to update this phone. Any ideas as to how to do that? I'm on build number ASUS_Z00A-2.18.40.12_20150529. Finally, when looking in CPU-Z to see the hardware it was reporting I noticed it said I already had root access which is odd? This has literally just been opened in the last 30 minutes and does not seem to be tampered with or a preowned model as the box was still in the shrink wrap plastic packaging that the box comes in. This isn't an issue, I just find it odd as I had to root my previous devices, zenfones included.
Z3560 with 4GB of ram comes from China wit China software,sellers in other countries changing it to EU ROM which is pre rooted,it was with mine but before I bought it seller has info in advertisements about it,I do not have any errors yet and I hope I won't get but I have problem with overheating it is warm on the top of the phone...
Did you stay on the rom that yours came with? Do you know if I am still able to flash other WW firmware onto this? I would like to be on the latest update for my device and this doesn't give me the option so I'm missing out on some of the newer features that I'm used to like disabling the bloat on the device

I have a 32gb 4gb 3560 zenfone 2, 2 actually. I followed the change to ww from cn guide to make sure everything was ok and have no issue with getting OTA's...
Everything works fine and one is on the latest stock 165 rom, the other is on a custom rom. Both had bootloader unlocked and both are rooted.
If you wish to find the latest pre-rooted rom, go to the pre-rooted rom thread made by Shakalaka, thanks again, and download from there, the latest is on Mega however.... Flash using fastboot...
He also provides recovery, boot and droidboot images,again, flash using fastboot BUT make sure you don't just copy and paste the same thing repeatedly, flashing the system image on the recovery partition after flashing the boot and droidboot image there already can really bork your phone...
Would suggest unlocking bootloader, seems to be easier flashing new roms and no issue with OTA's either. Bit more flexible if things go screwy...

HTC M9 (Canada) softbrick then baseband issues while trying to root

So I was trying to root my phone. I unlocked the bootloader from HTCdev and managed to install TWRP. I selected the read and write option though I think that may have been a mistake reading some of the posts on this forum.
Anyways the next step was flashing superuser unfortunately I flashed the latest version however apparently only till 2.64 works. This caused a bootloop. As I had no ideas, I wiped my phone and installed CM13. Now my phone boots up and runs perfectly and I can install other ROMs too but one critical error is that my phone doesn't recognize my sim card. It says baseband is unknown and IMEI number field is blank if I check using the dialer. My phone is S-ON.
This seems to be a common error around this forum but I can't find a solution which helps me.
Most people suggest flashing the stock rom but since my phone is S-ON I can only flash the Canadian videotron version which I can't find anywhere. I found nandroid twrp backup here in the following link but I don't know what to do with it. I put it on my phone but obviously I can't flash it nor does TWRP automatically find it to restore it. Do I have to flash it from my computer somehow like ODIN is used for Samsung(?) phones ?
Any help will be greatly appreciated.

Help to unlock the bootloader

So I have been trying to install Cyanogenmod 14, but I am kind of new to this, so I will probably seem pretty stupid. I basically tried to install it but forgot to unlock my bootloader. It was messed up, but I got help to install 2.20.40.184, so it works again. Now, however, I still want to install cyanogenmod 14. Partly because I for some reason don't get the OTA updates (I live in Denmark, where the Zenfone 2 isn't sold, so that may be it), so I've been stuck on lollipop since I got the phone. I don't even get a software update section under settings. So after all this, I tried to unlock the bootloader with the official app that you can download from the Asus website, however, when I do that, I get an error message saying "This device model is not supported". So looking for manual ways to root, I only found one that works with marshmallow, and when I download a ROM for marshmallow, I don't get the notification about an available software update. I also cannot enter recovery mode.
Hope this made sense, and that I posted it in the right place. Thank you!

Look for raw file .196 LP from RealYoti on here
Flash it in boot loader, with AFTool
You may have a china firmware converted to WW.
Once you flash try unlock ..or update from sd card to M ...Check my signature for flashing in AFT , also clues in downgrade link for how to write M to be recognised after a reboot for updating
If not got Chinese original serial you should be fine
Then when upgraded to M , Modder tool should be ok for unlocking bl in M
Then you can install 14.1
Hi, thank you very much for your reply.
Should I flash the raw file .196 even though I am using .184 right now? And which of the links in your signature is for flashing with AFtool (and where do I get AFTool?)
I have no idea if I have a chinese firmware converted to WW. Sorry, I am new to this xD
Yes, I am planning to use the modder tool once I have managed to update to Marshmallow.
Thank you very much

Updating to nougat

Hello All!
I'm sorry if this has been asked before but I'm trying to install nougat on my phone and having some great difficulty.
So far my phone is flashed and I was running TWRP 3.0.2 however every time i try to flash a lineage 14.1 based rom it would never work. (tried straight lineage 14.1, nutOS, DOT) none of them worked (wiped the phone clean, then received error 7, removed the assert lines that let in install but just perpetually boot looped) . My many a google searches makes me believe that that particular version of TWRP does not work with nougat. but that's the only version I am able to get working. any newer version of TWRP gets stuck in a perpetual boot loop.
So with that said, if my suspicious are correct and i need a newer version is there anything I'm missing to install a newer version of TWRP? if 3.0.2 is a good enough version to install nougat based rom's what am I missing on that end?
Any help at all would be greatly appreciated! and Thanks in advance!
Ninja edit: I'm runnnig the Z00A (Z551ML) and i've been using using roms/images meant for Z00A
I'm actually not yet used to these kind of stuffs but I guess your problem has something to do with either your twrp version or the bootloader version, this link might help you. http://theflamingskull.com/downloads/z00a/MM_BL_STUFF/

Yup that was it. My google-fu is off as i found my answer from a reddit post (5 seconds after asking this question in reddit...) My issue was that i was still on lolipop, the last OTA update and had no idea asus put out a manual update. worst part is, after unlocking the bootloader installing twrp, THEN installing that oem update, that might have cause my phone to crash mid update so it ended up bricking the phone...
I was able to Frankenstein it back together with old parts that I thought were no good, right now I'm on that last manual update and I gotta fight through a few issues preventing the boot loader from being unlocked.
Anyway you were correct, using the last OTA update updates the bootloader so I was stuck cause of that.
