Z008 firmware on Z00A!!!

I have bricked ma phone once then i take itto service center which is in different city..I have 4th model ze551ml but they put ze550ml firmware which is Z008..I want to go back on Z00A can any body tell me how did this???
[ZenFone 2 Q&A, Help & Troubleshooting] vali.cheche:
I think the smartest thing to do is take the phone back to the service that did this and let them take care of fixing it. This is the best/safest way.

If you want to do it yourself, DIY at your own risk. According to the forums these should be the correct steps:

1. Check to see if fastboot/recovery are for the correct hardware (ze551), and if yes you can use the adb sideload method to flash the correct firmware. You can see this in the fastboot info or the recovery header.

2. If the fastboot/recovery are not the correct ones and are also for ze550, then I think you must reflash these first, and only then flash the ze551 firmware. To reflash fb/recovery, you can use the fastboot flash method as for moving from CN to WW, with the proper boot/recovery/droidboot images.

I strongly suggest you find a way to get the phone back to that service and let them fix their own mistake.

Help

I ordered a zenfone 2 from Taiwan but its the ww version. My question is....I ordered it because it says that it supports 1700mhz/2100mhz and aws band 4...I am with Mobilicity in Canada...For the life of me I cannot get this stupid phone to recognize my sim card. Ive messed around with the settings, changed sim card slots...tried everything I can think of, and its still not working. Will this method (or any you know of) get it working?
[ZenFone 2 Q&A, Help & Troubleshooting] jimchee:
Won't work on 4G because the 1700/2100 mgs and aws band 4 is not active in Chinese version, no one to this point knows if it can be activated or if it is a hardware issue, so you will be operating on 3G till someone determines if they can activate the 4G radio
[ZenFone 2 Q&A, Help & Troubleshooting] nevynnoir:
Thanks for the reply...the issue is that i cant even get 3g...or any signal. its not recognizing my sim card at all. It just shows "CND Roaming" Any idea on what the hell is wrong? I stuck in a Chatr SIM card, and it detects that with no issues.Im very frustrated.
[ZenFone 2 Q&A, Help & Troubleshooting] jimchee:
However, the SIM card issue should be solvable by updating to latest build, the SIM card issue usually happens when you restore a backup in some older versions of twrp sideloading a full version of .59 version should let you recognize the SIM card, there is a download link for that Rom located in the general section here.

---------- Post added at 10:33 AM ---------- Previous post was at 10:28 AM ----------

You can also try doing a hard reset before flashing the Rom, both times I had this issue I had to reset my data before it would recognize the SIM card, for me I had to reset and reload the rom, but some here accomplished it by simply doing the hard reset, if you do the sideload you will need the Intel driver's installed on your computer for and to recognize your phone in stock recovery.

---------- Post added at 10:38 AM ---------- Previous post was at 10:33 AM ----------

You could also get the latest Rom from shakalaka which is posted in the root and flash to ww section here and use boot loader to load his latest stock Rom that is rooted, last time I checked there he hadn't yet posted .59 but there was an empty folder for that Rom.
[ZenFone 2 Q&A, Help & Troubleshooting] nevynnoir:
Thanks for that info.....I will check more of the forums here to see if I can find more info/posts by people who are having the same issue. I am not tech illiterate by any means, but I have never flashed a custom rom to my phone or done anything with bootloading. I have been doing some reading here on the forums about it and trying to wrap my head around what actually needs to get done, and I just need a little guidance.

I noticed there are a few different posts, describing a few different things, so for the issue I am having, can you please link the exact post that I should be following? Thanks so much.

Hi there. I'm probably one of many users with same problem. Recently I bought ZF2 on Aliexpress with mentioned firmware. Could you please share with me your opinions about potential risk of this operation. I want to point that I'm aware of all potential damages etc. I also have plenty of flashing, rooting experience with my previous HTC models (ville, desire z), but those models were designed for european market and this ZF2 apparently is not what i didn't know when i was deciding for this purchase, that's why I have some minor concerns - person from local Asus Service centre told me that this proces comes with additional risk due to market origin and allegedly its differences on motherboard it may. I'm not saying I believe her but I do not want to hard brick phone. What you think people. Is it really additionally risky due to the differentation of origin market.

Will be very grateful for any advices, opinions

dear vivix,

I'm quite confused, so sorry if it is a stupid question, but would like to know.

I've rooted my phone before and not applied any updates until now, while i deleted bloatware (running on pre-rooted 2.19.40.22 on ze551ml).

I've now downloaded a new pre-rooted system.img and all regarding .img's (boot.img / droidboot.img etc.).

Can I now update using flashboot with this pre-rooted system.img? only flash system.img or also boot.img etc?

And will I loose my files?

Or do I have to use sideload?

Sorry but the posts I've read all confusing and focussing on OTA updates. Normally don't want to unroot, should be possible or not?

Okay, first place the update file on your SD card and make sure you rename it to MOFD_SDUPDATE then boot to bootloader, from there boot to recovery and it will automatically update, make sure your present rom is completely stock with no frozen or deleted apps, should work for you

[ZenFone 2 Q&A, Help & Troubleshooting] jimchee:
It is for SD card update, recovery looks for SD card to update without the SD card you need to use adb sideloading to run the update file, there is a thread with instructions on this forum and also on zenfone support page, take your pick, after you boot to recovery and you get the broken recovery error hold volume up and press power momentarily to display recovery options, select adb sideload, start adb 1.032 from within the folder on your computer that has the rom, run adb devices and make sure the computer recognizes your phone, then run your command for sideload make sure you input the file name for the rom exactly as titled, read up on the sideloading instructions on the thread or Asus site and I personally write the steps down each time I do it as a guide for me when I am doing it, but you can do it however makes you most comfortable

Hello,

how can I do this point?

Upload WW_2.17.40.12 or latest Firmware OTA ( Full firmware ) file to phone storage (Phone storage/File.zip)

Which tool and command do I need?
[ZenFone 2 Q&A, Help & Troubleshooting] vali.cheche:
You connect phone via USB to computer and use the following:

Tool: Windows Explorer

Command: Copy + Paste

Then disconnect the device and continue with the tutorial. ;)
[ZenFone 2 Q&A, Help & Troubleshooting] king0r:
I don´t have any access to the phone storage in fastboot mode! Therefore I can´t Copy + Paste the OTA.zip file!
[ZenFone 2 Q&A, Help & Troubleshooting] vali.cheche:
Fair enough, tutorial is not very explicit about it. :)))

From step IV onward it is assumed you have a functional phone already and that you are booted into Android, not in fastboot mode.

Up to step III you should have a working phone good enough to boot Android and be able to perform OTA....IF you choose to also flash the rooted system.img (see last step in III)

If you do not want the pre-rooted image, then after step III jump over to step V and load the OS via sideload method.

Disclaimer: I am advising this from the top of my head, I have returned my Zenfone 2 2 weeks after I bought it (not my cup o'tea) so I have nothing to test on.

---------- Post added at 01:24 PM ---------- Previous post was at 01:20 PM ----------
