[Help] Failure of updating to 7.0 via flashfire

[Ivan Chung]

My phone is rooted before. Every time I used flashfire to update it. But this time, it is stuck when it is rebooting. It takes for hours....
What can I do with it?

Have you tried to restart the phone? If it won't start, can you put it in bootloader mode? If so, fastboot flash the images or adb sideload ota through recovery. If you have TWRP, it can flash images and/or zips.

 

[Ivan Chung]

yes, I can get into the recovery mode. What image should I flash? the img from google developer, e.g. 7.0 or the version I used before?
Thank you very much.

Sorry for delay. Adb sideload the ota.zip. It's probably the same one you have. You can download it (https://developers.google.com/android/nexus/ota) if needed then check the SHA-256 checksum to make certain it's a good download. Using ota saves data.

If you flash the image bat file, it will wipe your data so if you want to flash images, you have to extract them to flash each, not flashing user.img, via fastboot . Ota zip is easier.

adb sideload? would it save the data in the phone? because I didn't back up the recent documents. or any methods I can save the photos in the phone at this moment?

I am trying to use twrp...but it shows"unable to mount storage" " Full SELinus support is present"
What can I do?... I dont even get into the back up page and then flash the img.

First, the ota does not flash userdata so everything you've set up in your phone remains. With twrp, do you get something similar to this? I know pic is very bad. Bottom left says Select Storage. Click that.

then choose Internal Storage You should be able to locate the zip file.

Or, instead of choosing Install, go to Advanced and choose adb sideload. For this, your ota.zip needs to be on your PC, preferably (maybe absolutely) in your adb tools (adb, fastboot files) folder.
Sideload works with windows command or mac terminal commands.

now....
1. I can't back up....it told me "unable to mount storage"

2. it shows failure of decryption? can't find/open the internal storage

3. fails to sideload....as shown in the picture...I don't know why


I am just afraid to lose the photos in the phone......

Did you download a fresh ota? It appears (unfortunately I'm not a programmer) something in the file is missing. You could also try sideloading the version you had on the phone before 7 update. There's still the image flashing procedures which you can do either through twrp or bootloader. You want to extract all the individual image files from the download and flash one at a time. If you need help doing that, PM me. I don't think the unable to mount storage is the issue. Do you have the latest version of twrp for the 6p?
Do you have your photos backed up on Google? It's automatic unless you chose not to.

 

[Ivan Chung]

finally fixed!!!

I use adb to fastboot flash the img(all img except userdata) and succeed. It is lucky that I fail to use twrp to sideload the ota.zip file. Otherwise, userdata maybe cleared.(I am not sure)
I find twrp is useless this time.....can do nothing....

Thank you for your help!!

I agree fastboot was the best choice. Ota's don't wipe data, though. Well, anything could happen, but there is no userdata file inside the ota.
Glad you got it sorted out.
