Error Code: Secure boot 1002 - What should I do? Please help

Dear XDA community
I recently bought a LG G4 from an online retailer. According to their website they said it was a UK model, which according to the back of the phone beneath the battery it is: LGH815. But then after booting the phone the ROM being used was: LGH815T. Then I typed in the IMEI number and found out it was a: Verizon US model??
Basically I am having trouble identifying my model. The phone apparently came unlocked and rooted, but the person who sent it must have done something wrong because when I flashed a TWRP recovery image to the phone it comes up saying: secure boot error code: 1002.
The good thing is, is that I can boot into the device and still operate it as per usual. But what I want to do is bring the recovery back to normal. I was searching around and apparently there are some KDZ files that can be used just to flash the recovery? Is this correct? If so could you assist me in what I have to do to fix my issue which is: secure boot error 1002.
I would really appreciate any help regarding the matter. :crying:
Tried posting photos, but forum would not let me, all they showed was the model numbers.

Use LGUP-NEW ( https://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803 ) to install/flash ... the appropriate stock KDZ for your specific model once you ascertain it (LGUP - NEW may recognize your model and you can use that info to find the right KDZ). You will have to re-root the phone if you still wish to have root.
If you do root, suggest you might want to check out steadfasterX's [LOCKED][G4][TWRP][UNOFFICIAL] TWRP-in-FIsH for all locked G4 devices at: https://forum.xda-developers.com/g4/development/locked-twrpinfish-locked-g4-devices-t3573048
It has been tested on locked devices AND unlocked devices. Version 3 Beta 4 and 5 seem very stable and the links are available in the later posts on the site. It works like a charm and has been tested on a quite a number of devices now.
Addendum: I'm wondering if the online retailer may have meant it was carrier unlocked (i.e., so you could use other service provider's sim cards), not bootloader unlocked? That could account for the secure boot error getting TWRP to load.

open phone . take out mother board .. and read plaque model. if sprint flash sprint KDZ and LGUP. if H815 then do that .. thats the only way to be sure.

U have a refurbished model.Go to nearest mobile repair shop & take out your motherboard to see what model no is written on this.Then flash a rom accoringly. Don't flash any other rom just by assuming else you will brick your device.

Yes my phone is refurbished...
But how to flash the rom?
If I found it to be a sprint version and flash a sprint rom ...it will be locked?I am using phone in India...

Any chance to root the phone and install twrp?
Then flash a custom rom?
Please help...

Most probably it will be locked cause most higher Android versions LG has blocked rooting or unlocking..But you can always browse few threads.
Mine is also a refurbished model with F500L motherboard,LS911 body & had H815 global rom installed out of the box.I am currently on F500L Nougat locked & unrooted..I have tried almost every method.It failed to root & even to enter fast boot.
If you get your proper model no on motherboard then just flash the rom with ToT flasher in download mode with respective DLL.

Your network is locked?
You cant unlock it?
Can we degrade our Os to lollipop to get root?

Even I cant turn on the Enable OEM unlock under the developer mode...
Any more advices?

Please help.....

I have tried almost all h815 ans ls991 roms with all flashing methods but still unable to successfully flash my device...lg tot flash tool always show dl error after 4 to 6 percent of flashing...
Please help

Any idea's?

Pick the phone, and send it to the place where you bought it. If you have warranty the repair is free, if not, then you must pay sadly.

Still no solution, I even cannot enable OEM unlock under developer options...
It automatically disables it...
Please help

Just experienced this issue after changing sim card... Call and Camera stopped working over and over again.
How I solved it: Go to the specific app that is causing you trouble, and clear cache/files (too bad I only found this after 3 factory resets).

Maybe it will help ... LG G4 CAM

Was on oreo and did flash all to 7.1 by mistake.

So I was on Oreo and accidentally flashed back to 7.1.
Didn't brick it but now it doesn't recognize my sim even after flashing back to Oreo.
I tried to fastboot the tmo baseband but no luck there.
Anyone run across this or have any suggestions?

That was one of the 1st thing I ran across in the Oreo update thread. With development just really getting fired up I'll be surprised if you find a fix. If. I was you I would flash the mod that hides the unlocked bootloader warning and take it to TMobile. It's only a 5 dollor charge for defective devices. I've returned a total brick before.

So I am on the same board. The problem is I'm in UK and I cant claim warranty repair. Also my warranty was void in December soon when I generated bootloader unlock key.
SO what have I tried so far?
Hard brick bootloader to state when it is Qualcomm loader- only blank flash and Oreo Flash All is able to bring it back to live.
Ive also tried boot from B slot in twrp but it looks like my B partition is messed up. Fastboot will show red warning about no flashable A/B slot and only oreo flash can get it back to boot because it will oem lock itself.
When I get back fully on unlocked bootloader to 7.1.1 I cant update via adb sideload or update menu in settings. Both will fail.
Sim looks like it is detected on start but when taken out and slided back in it wont show up.
I have QCN area backed up with nv data but it wont help me.
Please note when boot is bricked oreo flash all will flash it on locked bootloader and will not show warning screen at all about botloader. However I was unable to boot to recovery from that point so I had to unlock it and flash 7.1.1 then oreo again.
So if someone could do nandroid backup of clear not set up rom it would be great. I can try restore it. I dont even know if twrp is able to do backup on A/B device.
Also if someone could read NV data from phone and share it ( from phone with working radio of course) would be really appreciated.

Can someone PM me NV backup? I need urgently qcn file. I think my hw partition is messed up. Please don't share it in this post as it can contain IMEI.

this is what i did, and why there is a giant post in caps in the thread that says not to do this. You essentially end up with a bootloader mismatch which hoses the radio. the only solution is a replacement.
and DONT DOWNGRADE !!!

Sorry but warning isn't clear. I did not enjoy Oreo and was looking for unlock method.
Also bootloader match to my current Oreo rom and radio but still no sim detected so I think it is hw partition messed up. When I flash retail Oreo on it bootloader just change itself to retail Oreo version. Still no sim.
Device is useable as paperweight with WiFi

I think I've found a way to unbrick your phones guys!
If someone still has their bricked phone could they tell me what state they're in? I managed to successfully unbrick mines but had to stay on 8.0

Everything about the phone works 100% except the Sim slot. It's like it can't read the Sim. It knows there is a sim in, but it can't access it.
On Oreo oem retail version.

I'm happy to stay on 8 but need my sim get back to life. All works fine except SIM card is not detected.
My phone boot as normal. When downgraded it won't accept ota's. It won't install it via sideload too. SIM card remain undetected no matter what rom and what version( T-Mobile, retail, etc) when I try to boot from slot B via twrp it won't boot. It will show bootloader screen with unbootable a/B partition.

Not OP, or guy with a link, but I did a similar bad thing and ended up on the retail Oreo without working SIM. What I did was take the modem file (the one that you fastboot flash to modem) from the tmo oreo zip and replaced the modem file in the retail oreo zip with the tmo one -- just change the name of the tmo modem file to the one that comes in the retail oreo zip and then run the retail flashall.
Still no way to get the latest tmo update that fixes some volte issues, though. Since I purchased within 14 days, I just added insurance and will probably end up drowning the phone to replace it... unless someone has a better idea. :/

guys i tried blank flash oreo on mine bricked tmobile moto z2 force and it isnt working, any help would be great on this , thanks.. and also i have tried many blank flashes some for even other moto phone models none worked so far.. one or two of them got really close the oreo one did but failed at last part... tried about hundred times and yes i even tried holding down power and volume button with no success it didnt work it did though recognize the phone but still failed trying to boot or flash it though... seems to me it needs either up to date or just different blank flash it seems, but i dont know that for sure...

[GUIDE] Flashing XQ-AT51 Firmware on XQ-AT52 Device

Disclaimer: I am not responsible for any bricks/ issues you may encounter following this guide. Although, I will do my best to try to help you if something were to go wrong.
MAKE SURE OEM UNLOCK IS ENABLED UNDER DEV SETTINGS BEFORE YOU DO ANYTHING BELOW
Update 2: 3/11/2021 : I see maybe deleting the .ta files may help avoid soft bricking, feel free to try it I have not personally tested yet to see if it works.
Update#3 3/13/2021 : If you are following this guide recently make sure you update to Android 11 first! Do not do any updates after the first one to Android 11! Then the flashing should work just fine. Tested and verified this on Taiwan XQ-AT52 to 51 firmware
Hello, I've managed to successfully flash AT51 firmware on my AT52 without issue using Newflasher.
Step 1 download = the US firmware/ whatever region is needed for you and new flasher/ the sony xperia drivers needed to flash the firmware to your device. Extract it to your desktop. Install the Xperia driver from newflasher if you need to/ haven't yet. Newflasher needs to be extracted into the same folder where the firmware files are that you downloaded from Xperifirm. This step is crucial!
Step 2 : Power off your Xperia and put it in flash mode by pressing down on the volume and connecting it to your PC via usb. (Do not use the USB C cable that came with the phone use a different one if you have one) You'll know it is in flashmode if the notification LED turned green and the screen remains off.
Step 3 : Open newflasher.exe
Step 4: type n then press enter
Step 5: type n again and press enter
Step 6 : This is when you should get to the flashing stage. Press Y and enter to everything you are prompted to. type y for yes to. This for me resulted in a successful conversion over to AT51.
Step 7: Once everything is done and it says you are safe to disconnect your phone please do so and then press and hold your power button until the phone boots up.
At this point you should have a fully working AT51 firmware!
Bare with me as I"m working on getting developer access for androidfilehost and will upload the files asap. In the meantime you can download newflasher and the firmware files yourself using Xperifirm if you don't wanna wait for me to upload.

Can you please help? I followed and i got a corrupted message and power off in 5 second.
I tried xperia companion, failed.
I tried to reflash newflasher with original firmware again, failed.

Can you tell me the model of your xperia phone? If you can still get it into flash mode when the notification LED turns green you may still be able to recover it.

Hi, I finally managed to restore it. I have to remove all the ta files to flash it, then it booted up.
Thanks for your respond.

I have using newflasher
After using 3 time xperia companion it work normal again

Hi, I didn't find this thread until after I made an attempt at flashing the device. I followed the instructions from the link below and ended up with the device saying it's corrupted.
https://www.xperiablog.net/2018/01/...-firmware-for-xperia-xz-premium-xz1-and-more/
I tried redownloading newflasher as well as redownloading the firmware I wanted as well as a new cable and that did not help. I reflashed it with this procedure listed above and it did not help.
Xperia companion won't let me do anything because it says the device is locked even though the device was not locked and there doesn't appear to be a way to unlock it. edited to add that I did get xperia companion to repair it successfully
edit again to advise I succeeded only after doing n and enter a third time then hitting y and enter for the final flashing step and that was successful in getting it updated correctly

Would it work to unlock my phone
Thanks for the guide!
Can I ask few questions please?
First is do I need to have my bootloader unlocked? I enabled OEM unlock setting in developer settings but that is only one thing I did.
And the second one is could this flash unlock my phone?
I am in this situation where my AT51 won't work with other sims except for Vodafone. UK.
I stayed with them for 30 days, (required time frame to get your phone unlocked) requested unlock code and it has been more than 10 working days but still have not received the code.
So today I did some searching online and found the service code to check if my phone is locked to a network and to my surprise it says it's not. So I am guessing that they have limited my phone to using only their sim through some other means andnot buy locking my modem. But this is ofc just a guess.
I kept chatting with the customer support and he keeps saying wait for the code which I do not believe is going to come, they have to unlock it on their end. But I am not sure about that. I don't think they are sure either..
Basically I'll wait fem more days maybe they will unlock it but if they won't when I am thinking maybe my modem is not locked and I could unlock it by flashing different ROM?
Or do you think this won't work?
Sorry for a rambling post. Looking forward to your reply. Thanks!

You do not need the bootloader unlocked as you are flashing official firmware.

Anyone know if you can flash a XQ-AT52 to a XQ-AT51 and then back to the XQ-AT52 firmware?
Sent from my XQ-AT52 using Tapatalk

I know this thread is a few months old at this point but I'm really struggling to flash to XQ-AT51. I've successfully flashed from XQ-AT52 Hong Kong (my original firmware) to the Taiwan version which is slightly better because of the messaging compatibility but I really want to get the US version. I have tried at least 20 times over the course of a full day and I have not been able to flash the US firmware without getting an error saying "Your device is corrupt It can't be trusted and will not boot" every time. I have repaired it back to the Hong Kong firmware (back when that was the one I had) and to the Taiwan version once I had that installed. But I have never gotten the US firmware to take without the "Device is corrupt" error.
My phone is the Sony xperia 1 mark 2 running the then default XQ-AT52 Hong Kong, and now running the default XQ-AT52 Taiwan. I've been trying to flash to XQ-AT51 US. I've been using newflasher v39 and the US firmware downloaded for xperifirm v 5.5.0.

So I was able to flash from the hong kong version to the Taiwan version and back with no issues at all. But I'm still unable to flash to the US version without the "Your device is corrupt It can't be trusted and will not boot" error that seems to happen every single time I try to install the US firmware.

Can someone make me a favor and can upload the latest ftf of Android 10 for the Xperia 1ii Single SIM?

The 1 II has downgrade protection, so as long as the firmware version of the US version isn't the same or newer than the highest version you've ever used you're gonna get the corruption error.
What you could try is flashing the newer EU version and then flashing only the older US customisation image. That's what I did for a while since US firmware was older than EU firmware, and it worked. Not sure if it'll work with Android 11.

im in the us and was looking to the 256gb version (i think its taiwan). is the hong kong or taiwan version missing anything? or is the only reason to flash to US to get better coverage with us carriers?

It's for better coverage and for VoLTE and Wi-Fi calling support. Also if you get a HK one with Android 11 you will be unable to flash the US firmware, because it is still on Android 10; and the phone has anti-rollback protection.

it arrived on 10 still, but its bugging me to update.

This isn't the case now since the US models have Android 11 too now

Can anyone confirm that this process has to be done using USB 2.x? I've read in a separate post that newflasher isn't compatible with USB 3.x, which is currently what all my computer use. Also, should I be using the newest version newflasher?
EDIT: Tried on USB 2.0 and it worked perfectly.

Any Guide to Unlock Bootloader or Change the Official ROM to a different one?

Hi there, so about few months ago like back in August, I got myself an LG Wing after LG announced that they were going to close the mobile division. I live in Malaysia and I asked help from a friend in India to help me get one and send it over.
After getting it in my hands, and after I inserted the SIM, it says Network locked. I bought the phone unlocked but it turns out, the phone needs to be used with a SIM from the same country, perform a 30 minutes call and then it would become unlocked.
Given that I stay in Malaysia, its impossible for me to travel all the way to India to unlock a phone. That said, is there any way I could perform either one of the following?
- Get the Unlock Pin to be able to use with other network?
- Change the India Official ROM with a different country ROM perhaps?
Thanks!

Hi there, so about few months ago like back in August, I got myself an LG Wing after LG announced that they were going to close the mobile division. I live in Malaysia and I asked help from a friend in India to help me get one and send it over.

Currently no method (yet) to unlock bootloader and install ROMs or GSI images, unless you get lucky like one member did here and get a demo model that's already bootloader unlocked from factory

What are the steps to root a demo model? I am thinking to buy a demo model. It seems cheap.

You don't, unless you hopefully get lucky and its factory bootloader unlocked. There's no way (yet) to unlock the bootloader to root every lg wing, demo or not
Don't buy a demo model unless its just a phone to play with. Not a good every day use phone
