Was your phone rooted?
If it was and you didn't unroot 1st that is why it won't boot...

I restored with fastboot system IMG

Cool, just remember before updating you need to unroot...

More details on fastboot system IMG?

Flash the system image in that thread. Boot, open supersu, unroot, reboot. Search for update through settings and apply.

Where do you put the IMG file? on the external SD card?? I'm in the same situation. I unrooted the phone first before i updated. Now it bootloops, and I cant go into recovery.

Have a look here:
http://forum.xda-developers.com/zenfone2/general/firmware-update-2-18-40-12-release-date-t3127193

OK I was able to get into recovery via this link http://www.asus.com/support/FAQ/1006346
Do I then do the factory reset wipe/data option ? Im currently doing this.. but its just sitting there at "Wiping data formatting/data..." Not sure if this will progress or just stay there?

boot in recovery, do factory reset wipe/data then wipe cache and just wait, otherwise try erase cache via fastboot

if eveything fails, download and flash the latest full firmware from the asus site
have a look here: http://www.asus-zenfone.com/2015/04/how-to-flash-asus-zenfone-2.html
has instructions step by step

OK it wiped it, then i went to reboot after it was done.. but its just sitting at the main screen now with the cursor circling.. I guess I have to try the method you listed above, damn.

first give it sometime, it takes some time the 1st reboot.
Patience bro i feel you

Well its not working. So if I use this info http://www.asus-zenfone.com/2015/04/how-to-flash-asus-zenfone-2.html
What is the file that I use with ADB to send to the phone? Which firmware, or whatever file do I use?

its the latest firmware from here:
http://www.asus.com/Phones/ZenFone_2_ZE550ML/HelpDesk_Download/
or
http://www.asus.com/Phones/ZenFone_2_ZE551ML/HelpDesk_Download/
example: for ZE550ML is the UL-Z008-WW-2.17.40.6-user.zip so you type: "adb sideload UL-Z008-WW-2.17.40.6-user.zip"

OK i did that.. it finished and I cleared cache and rebooted and I'm just waiting on main screen again.... I don't have to flash a recovery IMG file right? I can just sideload that zip file correct?

I'm right there with you on the formatting /data

boot in recovery, update from adb , then adb sideload (name of the firmware).zip

This is what I did. It is still on the boot screen with the circle cursor... It's not working apparently.

[Q] Need help ASAP! CWM problem.

Hey guys, this is my first post on XDA forum.
So I've recently bought a nexus 7, I used wugfresh's root kit to root my nexus but then it didn't work... so I've tired the auto root by chainfire. Then I was able to get root. So then I went to playstore and downloaded rom manager to install CWM. I went to recovery then I get this message:
E : Cant mount /cache/recovery/log etc.....
I've tried everything I can do such as researching, changing recovery, and watching a youtube tutorial but nothing helped.
Thanks.
I would start over from scratch using fastboot to flash a factory image and stock recovery. If your bootloader isn't unlocked already, unlock it.

DO NOT USE TOOLKITS. They cause too many problems. Learn to do things the proper way using fastboot. I agree with the poster above, you should flash a factory image to start over. Download the system image from here- https://developers.google.com/android/nexus/images
You need to unlock your bootloader-
Code:
fastboot OEM unlock
Then run the flash_all.bat. That will automatically wipe and reflash everything to get you back to square one.
Then you need to flash TWRP (don't use CWM)
Code:
fastboot flash recovery recoveryname.img
TWRP will automatically prompt you to flash SU when you reboot. Choose yes, reboot, then install SuperSU from play store, update the SU binaries, reboot again, and then you're done.

Well then I don't know what to tell you at this point. I know Lollipop has been causing issues for some N7 users, but I also know that wugs toolkit causes problems too so honestly I'm not sure what the root of your issue is. I think someone with more experience with Lollipop is gonna have to chime in here, I'm still on 4.4.4 on all of my devices. Sorry I couldn't be of more help.

[GUIDE] [HOWTO] Return to stock for Huawei Watch

Hi guys, since the development is started i think that we also need a way to restore the watch to the stock FW.
HOWTO:
- download from the following links the boot, recovery and system image;
- reboot to fastboot and:
Code:
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
and then go to recovery and do a wipe data / factory reset.
EDIT:
For some strange reason the system img flash didn't work properly on a device i could test. Here is the workaround:
1- First of all download the TWRP from the other thread and fastboot boot it:
Code:
fastboot boot TWRP2.8.7.0-Sturgeon.img
2 - Then push the system.img in the sdcard so:
Code:
adb push system.img /sdcard/
3 - Now flash it:
Code:
adb shell
dd if=/sdcard/system.img of=/dev/block/platform/msm_sdcc.1/by-name/system
4 - reboot

Will try to get to it today. I am booted up on your kernel now as a test (just fastboot booted it). Will do the same to test the recovery once I get a chance.
Edit: btw...when I have pulled images before, I had always done something like
cat /dev/mtd/mtd2 > /sdcard/boot.img (or wherever the boot image is mounted).
in an ADB shell. Do these things even have an sdcard location to temporarily store the images? Just curious on how you pulled them.

Having su installed. When you install skin1980's kernel, it uses chainfire's autoroot method, which modifies your system partition. So to make sure OTAs work, this is a way to get back to a clean system image that will pass the hash checks done by the OTA script.
I tried this and for some reason every reboot goes straight back to recovery. Did I do something wrong or am I screwed haha. everything seems to work correctly but then just reboots to recovery.

Now I just get an icon of an android on floor with chest open haha

That's the stock recovery.
restore back to stock
question, did bootloader unlock flash twrp then immediately backup my watch before flash the kernel. if i restore this backup file will it get back to stock?
Thanx

If you flash the recovery (twrp) and reboot into twrp to backup then you are backing up the stock boot, system and data.
Flashing the kernel will replace the boot.img only so restoring the twrp backup prior to this will restore your stock boot, system and data. At this stage your recovery is still custom (twrp)
So I want to return to stock to sideload the LCB43B update. However, I'm having issues following the directions listed. The recovery img and boot img flash fine but when I try to flash the system img, I get:
Code:
target reported max download size of 63963136 bytes
Invalid sparse file format at header magi
So I follow the steps to boot into twrp and it boots fine but adb push and shell gives error no device found. I unlocked my bootloader and flashed your kernel so idk if that is causing the errors.

Hi,
I have the same problem.... As it has solved ?
I'm uploading a zip file that can be flashed with twrp. It might restore stock system, boot and recovery so, after the flash, you should only relock bootloader anda you are good to go.
It's untested so only people that know how to restore the watch should try it.
Like i said, i dont own this watch so i can't test for you. Sorry.

Does anybody could be able to tall me what is the reason to root this watch? What are the benefits?

Has anyone thus far tried to relock the bootloader? I usually don't unlock any of my device until using them for a couple weeks to make sure I don't have a lemon. I'm curious if it's unlocked if Huawei would check, or if their system would show it was being previously unlocked.

TWRP recovery loop, what should I do?

Hey all. I got my mi6 recently. and I installed twrp on it, and flashed magisk. I was trying to install atmos in recovery mod, then I remembered that I hadn't already downloaded the file. For some damn reason I decided to wipe my device. however that didn't go well, and now I'm stuck on a twrp load loop.
I've already tried this command unsuccessfully.
Code:
dd if=/dev/zero of=/dev/block/bootdevice/by-name/misc bs=256 count=1 conv=notrunc
Also in desperation, I flashed my phone, rebooted it and etc.
What else can I try?
you can re-flash Twrp in fastboot mode, then boot to twrp, connect to you pc, it will recognize your phone as usb storage.
Down load you rom, copy it to your phone, then install rom by Twrp.

you may need to use a mobile browser. But there are mirrors.
I managed to fix the problem, by accident.
I just wiped Dalvik cache and data using the wiping tool in twrp.
after the reboot, TWRP was gone, and a fresh rom was installed with all my data, gone. However, that already has happened. So it wasn't a great loss.
I'm not technical, so I don't really know what made caused the loop, or how another wipe fixed it. So if anyone can explain it better, the floor is yours.
Thanks for the support.

Oh boy, your in pickle then! Then I suppose you'll have to....
fastboot format userdata
Then fastboot each image, which I think there are 21 of them if memory serves.
The command lines aren't that hard, just a lot of them. Start with the bootloader, then radio, then just start going down the list, ie.......
fastboot flash bootloader bootloaderxxxxx.img
fastboot reboot bootloader
fastboot flash radio radioxxxxxxx.img
fastboot reboot bootloader
Then just start flashing all the images from the secondary zip you'll find in the factory image.
but are they all the same target as the .img name

Unable to flash OTA update

Hi all, I have TWRP + Magisk on my device and I am attempting to update from PQ1A.181205.006 to PQ2A.190205.001.
Steps taken
1. Downloaded the OTA from here: https://developers.google.com/android/ota#crosshatch
2. Moved the OTA to phone storage.
3. Checked SHA256 checksum matches.
4.
Code:
adb reboot recovery
5.
Code:
fastboot boot twrp-3.2.3-3-crosshatch.img
6. From TWRP > Install > OTA zip file
Fails with the attached error. I have also tried sideloading through TWRP with the same result. Has anyone hit this error or successfully flashed the OTA update through TWRP?
I have not heard of anyone successfully loading an OTA through TWRP. Either restore stock recovery (install boot.img to both slots) and sideload with the Google instructions or run the flash-all (remove the -w) to use the factory image. Either way, you ere going to be reverting to stock recovery.
P.S. Your message doesn't make sense since you say you have TWRP on your device but then are showing that you used fastboot boot to run the TWRP .img file. If TWRP was on your device, you wouldn't have to use that command. You would just have entered TWRP with the adb reboot recovery command. I am guessing you are rebooting into the bootloader screen where either you run the TWRP .img or run the flash-all.
I also thought I saw a previous post somewhere that said you cannot skip an update, so going from December to February may not work.....not sure...
But definitely you need to load the OTA via regular Recovery using adb not TWRP....
Can you install a OTA?
I thought you had to perform an ADB sideload of an OTA.
Even then I am not aware that ADB sideload works for Pixel 3xl yet.
I have been flashing the factory image with -w removed.

ADB sideload works fine for the OTAs in stock recovery. That's how I've been doing mine.
On a side note, the Essential phone is the only phone I've come across so far that TWRP will flash the factory OTAs.

Flash them or sideload them? I never had a P2XL, but I had a Nexus 6p and I don't remember being able to flash that with the factory zips. That doesn't mean my memory isn't shot either.

Sideloading or factory image method?
I am trying to do an OTA update on my Pixel 3xl. I have TWRP installed and need to get back to stock recovery. I have the stock boot.img file and have attempted to flash with adb fastboot but I keep getting this error
writing 'recovery'...
FAILED (remote: Not allowed to flash (recovery))
Bootloader is unlocked
USB debugging is on
Any help would be appreciated.

Did you first extract the secondary zip file inside the factory image, and then placed the boot.img in your platform-tools folder, and the used the command..fastboot flash boot boot.img....??

Okay, and you are in fastboot mode and not adb from the OS as well I take it? Have you tried a different USB cable and port? If all else fails, you can flash the boot.img in twrp as well.

Hi all, I have TWRP + Magisk on my device and I am attempting to update from PQ1A.181205.006 to PQ2A.190205.001.
Steps taken
1. Downloaded the OTA from here: https://developers.google.com/android/ota#crosshatch
2. Moved the OTA to phone storage.
3. Checked SHA256 checksum matches.
4.
Code:
adb reboot recovery
5.
Code:
fastboot boot twrp-3.2.3-3-crosshatch.img
6. From TWRP > Install > OTA zip file
Fails with the attached error. I have also tried sideloading through TWRP with the same result. Has anyone hit this error or successfully flashed the OTA update through TWRP?

I've installed 3 latest updates from twrp ...
Download the latest OTA, you have to be in stock Rom and Kernel stock ... and have last twrp on your phone... Flash OTA and twrp installer to keep twrp ... restart in twrp for magisk or restart system ... benefits
sorry for my bad english.

Tap install on the twrp home screen. Then go to where you have the boot.img on your internal storage and tap image on the bottom right. Then select the "boot" partition, and swipe to install. This will return you back to stock recovery and kernel :good:

Well I managed to do that, but now when my phone rebooted the touch screen no longer responds. Very strange. It all loads fine and I can see my screen but nothing works. I tried to go back into recovery and I get the little dead Android guy laying on his back with a red exclamation point and "No Command" below it.
Any ideas?
