Hello everyone
So, this is my problem here, I got my G4 last week, rooted it to debloat, followed the instructions I found here on XDA, and it was working as a charm.
The problem came when I wanted to change the (micro) SD card to another phone, I took the back cover off, took out the SD card, and a warning message about the SD card might be damaged came on screen.
So I turned off the G4, after I was ready to put back the SD, tried to power on the phone again and the error message appeared.
"Security Error, Auth Fail #9" and then it just won't boot.
Hope anyone can help me.
I was on stock Telcel Firmware, had rebooted the phone several times before with no issues so far.
Never mind, I just reflashed stock firmware found
here: http://devtester.ro/projects/lg-firmwares/
then followed this steps
Tutorial: http://devtester.ro/projects/lg-firmwares/install.php
So, after a clean flash, it booted again, as Iv'e had it for just one week, nothing was lost.
Hope this helps anyone else facing this strange problem.
By the way, if anyone know something about the possible cause for this malfunction, I woud really appreciate you sharing info.
Cheers!
i Have had the same problem i was woundering if you could please walk me through the steps on how you fixed yours.
I recently just bought a new LG G Stylo with MetroPCS. this is my first time being with android so i took it upon my self to root the phone and see what all i could do with it. Everything worked fine for a couple of days then i tried to reset my phone and when it tried to come back on the lg logo cane up and it said Authentication fail #9. I try to factory reset the phone but it goes back to the same screen. I can not put the phone in download mode and my computer does not detect that there is a phone there. If there is anyone who can help me please it will be greatly appreciated.

How can be LG G4 H815P be rooted, have read many tutorials, but no one is for the variant "P" (Telcel).
Thanks!!!
Hello!
Well, I found out the source of the problem on "error 9".
As it happened again a couple days after posting the thread.
In my case, when I uninstalled LG apps, such as music and video apks, "error 9" would come up on next boot.
Follow the tutorials, the most important thing is to have the right version of SW to your phone.
Also, I had to download LG bridge, then a pop-up came telling that drivers for the phone should be updated, I just accepted the update and then my phone was detected on my PC .
If you encounter a problem, please provide me a little more info (with caps if possible).
Hope to help you.

@joyousfrank. I've just been de-bloating my phone and managed to get a Security Error problem and was hoping to use this method to get the thing live again. Trouble is that Google is blocking the LGFlashtool download link. Any chance you have another link or could maybe upload a copy of the tool somewhere? Cheers

I used this thread as a guide
http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765
(Follow the steps for International H815 10c Version)
This is the rooted image I used http://forum.xda-developers.com/g4/...on-root-lg-t3164765/post62251256#post62251256
After you download it just unzip it, and rename the .img file to "system.rooted.H81510c-EU"
The file must be system.rooted.H81510c-EU.img
Hope to help.
Cheers!

Hello!
The first thing to do, is to find the right SW foy your phone model (and carrier) as I read some problems when flashing other different than stock.
Look up here http://devtester.ro/projects/lg-firmwares/download.php there's where I found the SW for Telcel. Just input your IMEI on that page and it will give you a download link.
Then, follow this steps http://devtester.ro/projects/lg-firmwares/install.php
It's important to tell you that my phone wasn't detected by my PC until I downloaded LG Bridge as it comes with the latest drivers, so I recommend you to do this if you face the "not-detecting phone PC".
And for last, I suppose that there should be thread with a list of safe to uninstall apps (this is my first LG so not totally sure).
As there's enough room for apps on the phone, I just ended freezing annoying apps with Link2SD to avoid having the "Authentcation Error #9" problem.
Hope to help you, cheers!

When trying to upload factory rom into my Blackview BV7000 pro, it loads until I get to the md1img, then I get the status_insufficient_buffer error and my phone is bricked. Anyone have a fix?

Have you tried any other version of SP flash tools? I'm not very experienced but I've been messing around with the BV9000 pro for a few months and have found some success by flashing stock ROM switching up different versions of SPFT/scatter files. Granted not flawlessly, my home and back buttons don't work anymore. And the insufficient buffer is the error I get the most and have found very little on the subject. I never thought that I would know as much as I about phones(granted it's not much) but I'm determined to get this phone to work. So if I find out anything useful I'll come back and let you know, that is if you haven't figured it out already.

I don't have this device nor use the SP Flash Tool but, you may find one of the following threads helpful and don't be afraid to ask for some member guidance within one of them.

Hello,
I have a problem after the official update to OREO 8: the instant switching-on of the TV no longer works.
the option is regularly activated in the android menu.
With the previous operating system I never had this problem.
I also reset the TV to factory data with no results.
Can anyone help me?
Many thanks in advance,
Michele

they answered me from TCL ITALIA assistance, telling me that it is a known problem and that it will be solved (we hope) with an update ... update that they don't know when it will be released ...
Today I wrote to TCL EUROPE pointing out that this problem is not acceptable and that they give me solutions.
I will keep you updated on this.

What version is your Oreo?
Try downloading V534.
Go to.
https://support.tclelectronics.com.au/software-updates/
It's official TCL Australia Software Download Page.
V534 is stable and has no issue with Instant Power On feature.

Does this firmware update work for European TVs as well? Has anybody tested it?
I have the exact same problem on my TCL 50DP660, bought in Germany.
I don't recommend this TV to anyone because of this particular bug. So annoying. Terrible user experience.
Okay, I tried to install Australian v534 on my TV and it didn't work, failed on validation, probably the signature doesn't match
49 inseries Thomson / TCL Percee TV instant start
I have the exact same issue with a 49 inch 6 series Thomson / TCL Percee TV bought in Spain. I am in contact with the manufactures. So far they have advised me to download and install the latest software version and completely reset the tv. This did nothing and the problem persists so I am awaiting their next response. I will update the thread if I receive a working solution. They also told me that it is not possible to roll back to the previous android version.
Same problem here with an TCL U55X9006 QLED. With the OREO.
Any news..?!

The link has an error in it. Try replacing the first full stop with @ e.g. [email protected]
This is for Aussie customers though. Someone else on this thread tried it and the download mismatched with their tv. I have not had any success with the latest European version that tcl/Thomson recommended I download and install. I have not heard back from them since. At the moment I cannot pursue as I am in the UK and the tv is in Spain. I intend to chase up again in new year when next over there.
Any news please ?
I fixed mine! Tried a bunch of stuff, almost bricked my TV (seriously) but now Instant Power On is working! I'll explain exactly what worked for me and how to do it:
DO IT AT YOUR OWN RISK, I take no responsibility for any damages:
Download the file Update.pkg from https://drive.google.com/drive/folders/16RcAprPvyJuiXiEpEbIgvGlIW493kKtQ (folder v528)
Add it to the root of USB Pen Drive
Turn off your TV and take the energy cable out
Insert the Pen Drive
Connect the energy cable while pressing and holding the Power button (the TV button, not the remote control)
Keep it pressed until the screen flicks
You will see a Update in Progress screen (a small gray square in the center of the screen), do not turn off your TV until it's finished
Wait for it to restart. In my case after the update it also wiped all data, if yours does not, try doing it manually before testing Instant Power On
Remember to disable auto updates
Notes:
My TV is a TCL 50DP660 (Percee TV)
Before starting the process it was updated to the latest version (v543)
I chose v528 randomly, I have no idea if it only works on this version
I believe the Update.pkg contains the full image, while the zip is meant for OTA upgrades, but I'm not sure
Maybe the fix came from doing a full installation and is not related to specific version. If you're feeling adventurous feel free to try another version, I'm fine
The reason why I almost bricked my TV is because I tried other stuff before doing this.Just for documenting, this is the complete step by step I did (not recommended):
I was trying random stuff to make Instant Power On work, first I enabled developer mode, ticked some options including "Stay Awake", "Show Taps" and "Pointer Location". Of of them caused my TV to restart and enter a bootloop. At this point I was only trying to make my TV work again. I couldn't find a way to factory reset, so I tried installing the .zip update again with no success, tried to install v528 zip with also no success. Then I tried to downgrade it to Android 7 installing the Update.pkg from version v373. At this point not only my TV would boot, it would also present a lot of image issues, flickering and trying to install the v543 zip started to fail in the middle of the process. At this point I was convinced it was bricked and I lost the guarantee. Then I tried to install the Update.pkg from version v528. I had to remove the pen drive right after the installation was finished otherwise it would go on a update loop. I really don't recommend trying any of those things, I only did because I was already in a boot loop and still I think I was quite lucky. I wasn't even expecting Instant Power On to work in the end of the process.
Good luck! Please send a feedback if you try these steps!
Well done Lucasl! Thanks for posting this excellent write up. I shall be giving this method a try in March when I have access to the tv again and will feed back.?
Lucasls, where did you manage to download the various versions from? Do you have a link? In case v528 does not work on my tv.
Thanks

I found on internet, but I have no reason to believe they are tweaked. In fact I believe they are all signed (has a cryptographic signature that can only be made by the original vendor), because I think to install custom non signed by TCL firmware you first would need to unlock the bootloader. This is my experience with Android phones, I don't expect Android TVs to be any different.
If you Google for this Google Drive folder's link (https://drive.google.com/drive/folders/1vXfF1A3WtxTTU3CDRWraWyA7xd_dTGgr) you'll see it shows in many different forums with many different languages, but I can't know for sure who uploaded it in the first place... See: http://bit.ly/35KpebC
In my case I was desperate because my TV was already bootlooping when I tried to flash this image, so it's of course a harder decision when you have a fully functional TV.
I Ask you this becouse there Is a Little probability that that firmware are not for 55dp660 TV but for a similar model.
So the TV install the upgrade.pkg but TV gira in bootloop... :crying:
I have been searching and reading post after post about how to update my unit to fix an issue I am having. My bluetooth and wifi only work like 10% of the time after hard resets. I was able to find a post that has the same issue and a possible fix for the same issue here: https://forum.xda-developers.com/showpost.php?p=78204931&postcount=70
If anyone else has seen this issue please let me know
But it looks like I need a custom ROM or MCU to get that to URL fix to work? I have done a ton of reading but its just all overwhelming for me on what I should be updating/updating too. This is my unit information:
It seems like my manufacturer XRC is not that common and i cant find many information on what updates work on it. I would like to get the newest I can if possible while Im updating.
Any help would be very appreciated. I am sure this gets asked a lot, but I tried and failed to figure it out on my own :crying:
Thanks
anyone able to help?
thanks
no luck yet
Still stuck with no bluetooth is there maybe i way i can run the script without rooting it? and would any XRC MXU work with my resolution?
still no luck any help would be appriciated
I attempted to do a factory reset thinking that the system would automatically revert back to EMUI from Harmony OS. Apparently that was a big mistake because once I get to the last step after connecting to Wifi it keeps saying "Unable to connect to the server, tap to try again." I'm completely stuck and lost. Some help and insight would be greatly appreciated.
I also have photos of every step setup takes me through if anyone needs visuals. Once again, much thanks

Unfortunately not yet. I took my phone to a repair shop this morning and they were baffled with the scenario. They said they've never seen a phone get stuck on the final setup screen.
What about you, any luck? I can't find anything related to our particular situation when searching Google.
This problem can be solved by HCU utitlity (https://hcu-client.com/category/tutorials/).
It is paid.
Need unlock bootloader to recover factory Andoid version.
All phone requests are blocked on Huawei servers - therefore, VPN will not help here..
I also took it to the repair shop - and so and so to pay, but there is no alternative to this device yet.

Thanks. Which one did you buy, EMUI 11 repair?
As I understand it, this is the version that came in the box (Android 9)...
If it remains after installation Harmony OS.
I don’t remember the version EMUI...
