ilfat12 , In general, the question was asked not in vain and put an edge: derisive:
The solution was found:Club owners Asus Zenfone 2 Laser ZE500KL / ZE500KG (Post by gavrila # 54018605)
The only thing I can not remember is whether all TvRP issue a request for a recording mode)

in my opinion with version 3.0.
Yes, he did everything right. The only thing is, if you do not delete Magisk, but simply restore the stock boot, for example, the same TVRP (previously made backup or boot.img from the fastboot archive) or fastboot, then after updating it will be enough to flash only Magisk v7, you will not have to sew all the modules again, it is more convenient in my opinion, if there are a lot of modules)) Personally, I would do that :)
P.S. The easiest option is to return the stock kernel, it is through the same temporary TVRP to flash the backup boot made by Magisk, which is in the root of the data section (/data/stock_boot.img), which Magisk itself does when deleting itself, only it also magisk. img deletes where everything is.
By the way, the author saws Magisk hide and this is good news :)

Although no, the easiest option is to flash the stock booth via the fastboot, since we still need it to download a temporary TVRP. Then a temporary TVRP and rushed))
Although again, no)) For this option, you need a firmware archive for the fastboot. Extra zamorochki. Through TVRP is still easier. In any case, any option can be used. Who is more convenient))

Zamorochitsya now subject TWRP vs OTA. First discovered whether changing the hash partition system according to the selected mode at the first start tvrp or reset its configuration. Indeed, the hash changes, while just select the mode and immediately reboot rekaveri without doing anything else. It turns out that he is already changing mode selection system. Previously, I assumed (not on anything not based just speculation), it's just kind of protective option from accidentally changing system)) As a result of the PTA, of course, is not installed. Had, by the way, to revert to the previous firmware version to check it out. Experiments with the hash check is performed three times a hash varies and is always one and the same)
Also, experiments have shown that on my device, on others it is also possible, OTA does not check what is installed in the recovery section. That is, when TvRP is installed and booted into the temporary stock recovery command:

OTA is installed without problems. But the boot partition changes are no longer tolerated. From the DPR itself, as expected, it is also not installed, it immediately gives an error 7.
The conclusion is: the TvRP mode with respect to the system section should be selected Read Only, while the TVRP can be set to a constant, and the OTA can be sewn from the temporary stock recovery. There is no special difference, you still need a computer, but TVRP on board will never hurt and as a bonus, in the extreme case, you can flash OTA without a computer, restoring the recovery from the same TVRP, but you will need a computer to flash Magisk again.

back to your post. You have this opportunity. I apologize for the oftop, but FlashFire is perfect for you.
The steps are as follows:
1) Unlock bootloader.Keep in mind, as a rule, all data on the smartphone is deleted. Everything is clean.So take care of the backup.
2) Download temporary TVRP in Read Only mode.
3) Flash SuperSU 2.78 SR1
4) If you want to flash non-systemic Xposed 86.2 from topjohnwu. This version is intended to be installed together with SuperSU.
5) Install FlashFire from the market.
6) Upon receipt of the OTA agree to download, but do not install. Most likely the zip will be in the cache section. Flash it from FlashFire, by no means out of recovery, since Ruth will fly off and remember his name, you will need a computer again. Before this case, deal with FlashFire what and how.
Yesterday I personally tested it, no errors, everything is beautifully updated. FlashFire will restore the boot itself, flash the update, restore the Route and reboot the device. And backup will do, if necessary. The perfect solution if only Ruth and Xposed are needed. This is all provided FlashFire supports your device.

Why is that? Nothing was removed even after the firmware, not to mention the bootloader. : yes2:

888nn I know that there are ways to unlock without deleting, but it is still better to be safe. Many on this stung.
In general, it is so intended that all user data is deleted during this operation for security reasons.
Fastboot oem unlock is supposed to delete user data.

Unlock ways and their consequences are best viewed in the subject of your device. I just cautioned just in case)))

ilfat12 Of course, backup should be done without any questions.
But here is to remove a forced, controversial statement. Although he is a supporter of the "clean" installation.

ilfat12 ,
Is it possible, instead of SuperSYU and Iksposeda, to simply flash Magisk? I Xrosed so much is not needed. Only a non-systemic root is needed.

s710,
then why do you need Magisk at all? SuperSU is the root, and the most non-systemic. Plus, he has a suhide tool for hiding the root from programs that don't need to see it. For suhide there is a graphical shell in the market. In your case, simply the best solution.

s710, Moreover, even BusyBox is not installed systematically if there is a non-system SuperSU, but you probably don’t need it)))
The most important thing with the help of the root is that you do not accidentally hook the system))) so it is important that you are going to do this using the root))

ilfat12,
In nature, there are non-systemic root, bizybox, hposed, also mounted through the init.rts
They also do not touch the system.
Until I understand what the beauty and convenience of magic is ..

gavrila , Type in the modules)) But while few of them. I for myself have made such a module, push there anything you want to change the system. Such as all kinds of helpers for programs that need to be a system for producing large may be changing configs codecs, so out of the box was ac3, changing to a modified dialer. You can delete an application system without disturbing the system. True to this, I use Titanium (freezing), but the possibility is there. You can change the settings build.prop. Probably something else you can do. By the way, non-systemic viper4andriod available as a module.
I edit directly zip itself using X-Plorer.
In Magisk, the built-in BusyBox and in my opinion the hosts file is mounted on top of the system one for programs such as AdAway. But I use the Xposed MinMinGuard module. In applications, it cuts ads better, but it does not cut in browsers, unlike the version with hosts.
Well, about something like that))

Simply put, you can do almost anything with the system and it will remain even after the update. But not everyone needs this)

Where is he?
I did not find it in the / magisk section

Ahhh ..
Lies in / data / magisk without symlink .. and it does not link anywhere ..
With such a bizybox, there is no sense for the console command busybox to my android in this case is unfamiliar

Copied the busybox binary from / data / magisk to / magisk / phh / bin and commanded busybox --install -s / system / xbin
Now all the links on the ground

Post has been editedgavrila - 13.10.16, 18:12

gavrila , in version 7, I did not find the busybox binary itself, maybe a mistake or intentionally done, so yes, Android doesn’t know the busybox command, but all the utilities are there and the system sees them. Trite try the command which wget and everything will become clear.

symlinks are not needed if the path to executable files is in the $ PATH variable
Dial in the terminal $ PATH and it will be still more clear)))

Really))

I just can not see the root of the programВ® Secure Settingsin conjunction with the mag and phh-root ..
All other applications of the root see

gavrila Well, if the applications see, then I think this is enough))
I have Root Check, for example, sees Ruth, and BusyBox does not, but it is clear why)))

No, not really
applet which is in the toolbox ..
but try to launch the who applet - it is not in the toolbox .. and it is not called from the bizybox.
I looked at $ PATH and saw the path / magisk/.core/busybox, but there is no such folder there ..
Apparently the author forgot to make a link to the / data / busybox folder in the /magisk/.core folder

no matter where it is, it matters where it finds wget.is called. Again, try which who

there is such a folder. She is hidden. If the first character in the file or folder name is a dot, then the file or folder becomes hidden. In this case, the folder .core;)
