[Q] OTA Update Fails

Today i get an update OTA
i downloaded it and wanted to update, but in the Update-Screen, the progress failed and my phone reboot
i have rooted my flex2 (h955) and the software recognized it and throw out an error
is there any way to update?
i searched the problem in google, but google doesnt found anything and in the G3 forum stands, that root is no problem with stock recovery and ich have stock recovery

You might have to unroot before doing the OTA update.

Which version of the LG PC Suite did you use?
There doesn't seem to be one available for the Flex 2 yet on their main site.
*Edit* Software tool downloaded and works fine.

could anyone post links to the tool/s to update the sprint flex 2 please. i too got the OTA update and failed, most likely because im rooted. but anyway im just trying to update. also anyone also with sprint and updated notice any performance differences or better signal after update.?

I'm using Flex 2 after the root is not updated. When I unroot the LG logo hanging Flex 2, now I needed stock rom and file tot

you can try to flash this:
[KDZ][H955] LG G Flex 2 stock .kdz
And then you tell us if it worked or not.

The message is no problem, only appears at startup. But no phone reception is a ****ing thing.
Have you installed the correct one for your country? if it is on the list.

Which one did you get? LG PC Suite 4.3.41? Where from? I can't find it on the LG site for our phones.

count me in the same boat :/
have the sprint version of the phone and woke up this morning to a prompt that there was an android update. with my brain not being awake yet i went ahead and told it to update, not thinking about root preventing the update. So went about my morning routine and came back and the phone was booted back up, but obviously the update didn't apply as i was still on ZV4, not ZV5. when checking for update it says there are no updates available.
can anyone help me/us out and post some steps for how to unroot and reapply the update? i'm good at following directions, just too new to this stuff to be able to figure it out on my own

see provider but no signal

anyone have any tips on forcing the OTA to download again?i've disabled SU, rebooted, and factory reset and it still says i'm up to date when checking for an update. or is there a way to download the OTA and update the phone some other way?
really want to check out this update and see the improvements, just can't get it to go after trying to update this morning while still rooted

I tested all the files and I have no message and signal works perfectly.

woke up this morning to the prompt that there was an update available again, not sure why it does it overnight but won't when i manually check for update..... anyway, i disabled SU, rebooted, then started the update and watched it this time and in the middle of the upgrade it came up with the android guy on his back and it said error. after a bit it restarted again and was back to where i started, no update.
so it looks like i need to unroot. would appreciate any help on how to unroot so i can apply the OTA, thanks!!!!!

Here with a sprint flex 2. First time I tried ota update I was rooted and it failed. A few days later the update notification showed up again, went ahead and unrooted, tried the update and still failed. I'm not sure root has anything to do with update failing now. Could be something else. So far I haven't read about anyone successfully completing update and reporting it.

I was getting the same error message about being rooted even after un rooting the device.
I installed the lg pc suite and upgraded to 10d that way and then re rooted using the method on this forum.
It looks like there may be a flag thats triggered once u root that doesnt get removed even if u unroot it.

ugh! i can't even get my phone to connect to pc suite to try and "fix" it so i can attempt the update

Factory Reset, result: "Unfortunately, Android System has stopped"

AT&T D850, rooted, still running 4.4.2.
Yesterday having terrific wifi connection problems...on all wifi.
After hours of work, decided to Factory Reset.
Did on-phone software-based backup and factory reset.
Upon reboot, I get black box message: "Unfortunately, Android System has stopped"
I've had a phone repair teck look at it and he could not get very far. You can actually hit "OK" after the message and y get a microsecond to try and hit something on the screen. he was trying to clear the storage cache.
So, after numerous retries at hardware (button) based factory reset with same results, I'm the owner of a bricked device. Although I rooted to get rid of AT&T trash on the phone, I had little interest in custom ROMS and was afraid of bricking my phone. And after a simple factory reset, that's apparently exactly what happened.
So as if this point, I have a data connection with the carrier, and I can access internal memory via USB...but obviously I cannot go into settings and enable Developer Options or USB Debugging or anything like that.
What are my options to restructure things running purely thru a PC/USB connection?
Any help would be SINCERLEY appreciated.

When I go to the link for LG Tools...all I see is ads. Anything I click for the download leads me to unrelated software downloads. How do I actually dl the LG Tools? Actually...those links for downloads all result in Google Ads for unrelated software products. Frustrating.

Wait what? All the links in my guide work fine. If you look after you clicked you have to enter a quick catch code and click download. That is to stop abuse.

I think your misunderstanding it, I think your looking at the ads and not the actual download link.
After you enter the code it will count down 8 seconds then you can click download. It brings you to a page with the download link.
That's the download link you then click.

For example, when trying to dl the last link...I get a big circle link at the top to dl something about CCD Color Camerara...at the bottom there are three smaller circles...for Fix Windows Update, Start Download/Update Windows 10 Drivers, and Free Driver Upgrades by sparktrust.com.
Nothing else. I don't find anywhere to dl the real file...it's just spam.

OK- I have all files from other sources. Step 2: Install LG Drivers. I'm sorry- I'm really not a stupid person, but I don't know how to "install".
Do I copy the files in the zip to a certain place in the internal memory of the G3?

Well, OK, I just ran the LG Drivers and it installed to C;\drive.
So , the next step, Install Flashtool...How does this happen? I extracted everything in the zip to it's own folder. I don't see how to install this to the c:\drive.

You extract it and run it. It doesn't install.

When I click on the FlashTool application, I get a dialog box with bunch of parameters. It doesn't look like it's going to install anything...or run anything...it's just a bunch of parameters that' I don't understand. One of which, is "Ty;e" and the default is CDMA. I KNOW this phone is for AT&T- so I should not be messing with anything for a CDMA system/Verizon/Sprint. Totally confused. I'd really appreciate your input...if you want I'll make a contribution to your PayPal or something...I know I'm a PITA. I'm an intelligent guy that works with computers all day. I'm not a grandma or a noob...but you're way more advanced than me and I'm having trouble making the connections that you are completely familiar with.

Firstly you would keep it on cdma as that doesn't apply to what the phone network or is for. Also your using the Wrong method. You would use the TOT method. Tot method doesn't ask for what your seeing

issues after mm upgrade
Here's what I experienced after update...
Once you upgrade you can't flash back to stock. LG flash tool fails because it couldn't detect the model. After setting up McAfee it disables root and usb debugging. You have to go into McAfee and turn those options off. So it seems like once you go to mm you can't get back to lollipop. I'm also having proximity sensor issues also with the screen going black during a call. I guess once we can get root I'll be able to install another rom.

Hi, I got the notification and I was not in WiFi network so decided to cancel it and check it again once I got to wifi zone. But when I checked next time, I just get a message, your phone is uptodate. I tried rolling date forward to circumvent the 24 hour check, but no luck. Any ideas to get the update notification back ?

no luck updating
tried the update today, it just sends me to twrp recovery screen every time

You can't install a factory update while rooted. Come on guys you should know this.

Not sure if there is an "anti roll back" But You cannot use flashtools once updating to Lollipop you must use LGUP.

Its KDZ. the D850 is TOT method only.
My Guide:

But remember its your own risk, not sure if downgrading will brick or not yet from MM on the AT&T Model.

FWIW, if you're experiencing DND issues after the 6.0 update check settings > dnd > advanced > schedule. kept noticing on my moto360 it was switching to dnd for no reason. turns out some scheduling magically appeared. been running 6.0 without a hitch since last night. had to manually disable at&t video calling and a few other things but im happy with it thus far.

You have to do a hard reset through stock recovery. Don't do it if you are using a custom rom. If you are not experienced I recommend you wait to see if you get another update notification

That is because flashtool you cannot use if your on MM you use LGUP with the TOT file.

[Rom] Bootloader Recover Huawei Watch 2 BT LEO-B09/LEO-BX9

Hi Everyone,
As some of you have tested the first firmware (4G) available in the Bluetooth version, our friend @mcdull and @sorayahya have fixed a broken Watch using below firmware.
Sorayahya will post the manual in this same thread so all of you can make your watches functional again.
Link: https://mega.nz/#!gqQATbga
Decryption key: !mD2smD4jEq_FOkhE1uy0PQ5uf6XYpxR0wxxkM6msPiE
Special thanks to @mcdull for preparing this file to all of us.

So after downloading the above files from dr_chch's post extract the files. After that we will need to get QPST which has the program called QFIL which we will be using to unbrick the watch.
Download “QPST 2.7 (QFIL)” from HERE and extract it to an empty folder. Install QPST by double clicking setup.exe.
Now you want to plug in your Huawei Watch 2 to the PC using the charging cable that came with the watch.
At first you might get a notification from the PC that the usb device is unknown, if that happens you will need to hold down on your watch's right top button for around 30 seconds. After that you should get a notification from your PC that a new device was plugged in and it will start to install a new driver. Once that's done you should have a "Qualcomm HS-USB QDLoader 9008" device show up in your device manager.

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
We won't be needing the storage device to show up so if it doesn't for you that's alright.
Next we will open QFIL from start menu, if it's not in the start menu you can locate it by going to Program Files\Qualcomm\bin\. You should see "Qualcomm HS-USB QDLoader 9008" written on the top, if it's not then click on the "SelectPort" button and then select "Qualcomm HS-USB QDLoader 9008". After that Insert all the necessary file needed by QFIL:
(1)The programmer will be prog_emmc_firehose.mbn;
(2)Use the rawprogram0.xml;
(3)Use the patch0.xml;
(4)Hit “Download” button.
If the process you did with QFIL finished successfully, the watch will boot again. If not then try to restart the program and repeat the same process again until you succeed.
At this point your watch is alive again but without a firmware so you will need to flash the correct ROM through fastboot.
For that you can check out the guide dr_chch made here:

Thanks for the files and the recovery guide. Please make sure you understand the below before your recovery.
1. You will probably lost the original MAC Address of your WIFI and Bluetooth. But at least the device will work with both functions, it will assign another MAC Address for you.
2. The recovery file includes only the boot loader, you still need to boot into fastboot (holding the device power button until you feel it vibrate. Then quickly release and press the power buttons) to flash the latest ROM downloaded from here.

Mod Edit
what you can help?

Hi Everyone,
As some of you have tested the first firmware (4G) available in the Bluetooth version, our friend @mcdull and @sorayahya have fixed a broken Watch using below firmware.
Sorayahya will post the manual in this same thread so all of you can make your watches functional again.

You wont need this file as this is for de-bricking the BT version only.
And the mega link works just fine.

I'm getting this error. I tried multiple Desktop's and win7/10

Just learned of this thread......
I am wondering if anyone got the LEO-DLXX Watch 2 4G working again? Mine is recognized in QFIL as a qualcomm 9008, but that is as far as I can get. Has anyone been able to get the bootloader working with the files in this thread? I'm not sure what happened to mine, but it got bricked while installing the global ROM Huawei2_NXG46W_Global_4G. It is strange how it worked for so many people, but not mine. Any help or guidance is appreciated.

The ROM worked for you or were you able to recover the boot loader? Has the LEO-L09S recovery found here: https://forum.xda-developers.com/watch-2/help/flashed-huawei-watch2-power-t3632341 worked for anyone?

Are you getting the sahara protocol error message as well? Are you trying to use QFIL to restore the bootloader on the LEO-DLXX watch?
Two strange things happened when flashing the ROM from this thread: https://forum.xda-developers.com/watch-2/development/rom-huawei-watch-2-4g-l-09s-global-t3602205
First, it took a very long time for the device to show up with adb devices. There was a device there, but it wasn't listing every time I connected. As soon as I did, I went ahead but probably shouldn't have. Second, the fast boot process seemed to go along as normal (I have flashed a few ROMS, but never on a watch) until it came to the system. The system fast boot process took seconds....not longer than bootloader, boot, etc.... That is something I have not experienced before and thought it may have to do with a smaller system for android wear, but in fact it is not that small. After that, well it is bricked, but at least showing as a qualcomm disk.
I guess I have to wait until the recovery bootloader (firehose, rawprogram etc..) is leaked for the LEO-DLXX device. There is no possibility of returning the device or paying for service since it was bought in China and brought to Canada where it hasn't even been released yet.

Yes everytime I tried to flash the .mbm file I get the sahara protocol error saying it is 0 bytes.
I also tried draining the battery fully and I switched between many desktop's
And still no luck
And quick question: my friend has the same watch. Can i do something with that to fix my own?

Has anyone successfully flashed the Huawei Watch 2 Pro (LEO-DLXXU)?
I'm keen to get my watch compatible with Play store apps rather than Huawei App Store, but I'd be keen to hear from someone who has been successful.

Hi @dr_chch, do you have the files for DLXX ? I tried to flash the Google P preview forgeting that I have a 4G and not BT model and It totally bricked my watch...

same here, i just wish someone would help us find the right files for the 4G version.

Same problem with my LEO-DLXX. I noticed that 1 of 3 files needed to flash has wrong name
rawprogram_unsparse.xml , nor rawprogram0.xml
Is there a problem with this?
