Hi, I feel like I screwed up! It's my first time doin this stuff. Could someone help me please. I managed to unlock the bootloader, so I went i tried to restore the abl_a/b partitions but my phone died right after that. I think what I did wrong was not naming the backup files properly so I probably mistook abl_b with modemst, and loaded modemst1/2 into either abl_a/b.

Now it wont boot at all; black screen. Can someone tell me if it's possible to bring it back in this state? What should I do?
[LG G8X ThinQ Guides, News, & Discussion] foenicxxx:
You have not mentioned about your device variant, anyway, try to get to download mode and flash the KDZ of your device to get back to your stock rom. Then afresh, go for the bootloader unlocking.
[LG G8X ThinQ Guides, News, & Discussion] civenci:
Hey thanks for replying. Sorry, I didn't think saying the variant was necesary. I got it fixed tho.

It was impossible getting into download mode since my device was not even booting in any way. neither it was being detected by the pc. But i figured out that if I pressed the power button + vol down button at the same time for a while the phone would vibrate for half a second. So with this finding I tried presing the combo keys and presing vol up after that little vibration and the deviced showed up in the device manager. The device had booted into EDL!

So from there I was able to re-patch the abl_a/b partitions, the device booted, stuck in a bootloop, understandably. But it was an easy fix since the only thing left was doing the stock rom flashing, aaand redoing everthing again.

Everything is fine now, I even managed to root my device and got rid of the "Can't find matched carrier. Check NT-Code: 0" thing. I tried fixing the FP scanner by relocking the bootloader with fastboot oem lock but It remained unlocked no matter what. Don't know if that fixes FP to begin with.

Thanks again for replying. And I hope this info ends up being of help for somebody else.

Good to know that, you got the device back on the track. A bit tricky with LG 😜

As a little

As a little update to this I was finally able to bring the FP scanner back with the BL unlocked. Don't try relocking the Bootloader since it prevents the device from booting if rooted. The guide I followed is on XDA.

Now I only need TWRP so I can backup in case I break something in the future.
[LG G8X ThinQ Guides, News, & Discussion] hieppo:
Could you please let us know what KDZ (download source) you used to downgrade using LG UP?

I currently have BL unlock and magisk running great. However, I like to try to fix the FP scanner by following the XDA guide. However, it's difficult to find the KDZ to use with my Canadian variant. I am not sure if it is safe to use KDZ from the US or others t fix the FP issue.

The XDA FP scanner fix thread does not provide enough information on what happen after you downgrade. What do you need to do to at least upgrade back to Android 10 latest updates. Would OTA for your country work or would you need to find the proper KDZ and LG UP? Once upgrade, would FP scanner still work or would it revert like back originally?
[LG G8X ThinQ Guides, News, & Discussion] civenci:
I downloaded my device's KDZ at LG Firmwares.

I was also concerned about this because my variant is regional and not country specific. When I looked up for my model it showed multiple options. And i mistook the proper KDZ for my device with another multiple times. But LGUP warned me bout flashing the wrong firmware so I simply kept trying different firmwares until I got the right one (LGUP won't let you flash the wrong Firmware, that's what I can tell from experience).

If you downgrade it will simply prompt you to upgrade like it did when you were on Android 9. you can go back to android 10 that way after you get your FP scanner working.
[LG G8X ThinQ Guides, News, & Discussion] hieppo:
I was able to downgrade and fix the fingerprint scanner issue. I went through all the OTA updates. Surprisingly it works fine.

However, once all updates have been process. I tried to magisk the device by following the universal unlock and magisk thread. I did exactly the same thing the first time around but Magisk would not install and activate.

The first time around BL unlock and Magisk works great but Fingerprint did not work. Now fingerprint works but I am unable to Magisk it.

I used the same _a slot as when I first started the process. It did not work so I tried to go back into fastboot just to confirm if the slot change but I can't go back into fastboot for some reason. I tried both combinations with power on and off but to no avail.

I don't know what else to try now.
[LG G8X ThinQ Guides, News, & Discussion] civenci:
You may need to get a new modified boot image and try flashing that?

what method did you use before to flash magisk?
[LG G8X ThinQ Guides, News, & Discussion] foenicxxx:
You have to use the right and correct Magisk Patch as per the version of your device. In your case, after OTA updates the firmware version changes and the old patch wont work. Just to make the things clear, an example, you did Unlock BL and root with "B" version and got back to "A" version firmware to make the FP to work, later with OTA, you reach the firmware of "C" version, then the old Magisk patch will not work. Here you have to use a newly patched boot image as per the recent version.

If my reply is irrelevant or wrong, please update your question.
[LG G8X ThinQ Guides, News, & Discussion] hieppo:
Thank you for replying. I now know after I redo the steps from step 1. I notice teh switch in the slot. That was what my mistake when I tried to magisk the 2nd time. When I followed the step originally, everything was followed exactly and it work.

After I fixed the FP scanner, I notice that the BL was already unlocked so I did not think i needed to find out the slot used. And flash the Magisk patched img into the slot a. which did not work and cause me to load the original boot from the first run. This cause the fastboot loop.

Anyway, I could not boot anymore so I downgrade using LG UP and KDZ and restarted.

Everything is good now. BL unlocked, magisk and fingerprint all works. I am skipping TWRP for now since there is no rush for the custom rom yet.
[LG G8X ThinQ Guides, News, & Discussion] foenicxxx:
Glad you got your device Back in working (y):)
[LG G8X ThinQ Guides, News, & Discussion] hieppo:
One last question, Magisk is installed but when I check the safetynet, I receive the error "SafetyNet API Error".

For other devices I Magisk, I never receive this API error and get individual status for basicIntegrity ctsProfile and evalType. I just correct these.

I was wondering if there is any different with the way G8x is patched and installed if we would be able to get all the same feature.

I did notice I that Netflix is not available for installing. I assume this has something to do with root. Now Netflix is not high on my list of apps that I want but it leads me to believe other apps that i need to install that is not available is due to root being exposed.

What remedy did you do on your G8x or if any?

Thanks

Hi, Thanks for this tutorial.

This exploit works on G850UM variant...?
[LG G8X ThinQ Guides, News, & Discussion] arbiter99:
If the UM variant is one of the traditionally GSM varieties like Canadian variants, AT&T and Tmob (and I am not familiar with the other American varieties,) I think it should minus the AT&T variant.

did anybody get this working on a QM version? I have US unlocked and bought with android 10. a month ago I tried and updated to latest android 10 after having dl'ed the earlier firmware. I have 2 G8X's and ran into different problems with both. the second one I learned a lot about how and what to flash but still no FP work. I am waiting for LG to put out a halfassed android 11 and hopefully update it to stable, or a few more people whip up some light custom stable roms. hopefully another guide or some updates will make it easier. I want that root but so far the workarounds I have are getting me by.

Check your device version and country, find out the person who holds the same, request him to send those files. Flash them back through QFIL. QFIL is a double edged knife...

Looking for a ROM to flash my Universal but there are just to many of them. Which one is really good, fast and stable? Are there any German ROM#s available besides the T-Mobile one?

Thanks
[JASJAR, XDA Exec, MDA Pro ROM Development] orb3000:
Depend exactly your needs, try to do a SEARCH on this forum, at least you will find 6 marvellous ROM´s.

Personally I would recommend Tomal ROM´s as in my experience gives the best performance-stabilty and support

Good luck
[JASJAR, XDA Exec, MDA Pro ROM Development] dosada:
I have just updated with this rom but there are quite a few problems. Firstly some of the language is in german as it was previously before the flash. The radio is still version 0.0.0 as it was after i used the unlocker. Also is there is still the tmobile logo on boot up which i hope i can somehow get rid off.

Any help is much appreciated.
[JASJAR, XDA Exec, MDA Pro ROM Development] orb3000:
Perhaps some master of more knowledge can give us a clue, I honestly don´t know why is happening that.

My only recommendation would be to have a good look into the Wiki, over there you will find out how to install a different radio version when you upgrade a ROM.

Also in the Universal section there is a post (Don´t remember exactly where) where you can learn to change your bootsplash screen. I made it and it´s easy.

Good luck

[JASJAR, XDA Exec, MDA Pro ROM Development] loithuxua:
Impossible to say for sure as the matter is that one rom may run well with a HTC uni but might have lots of problems with another HTC uni. This is the truth, even though the two PPC are of the same kind. It seems to be strangge but happens to my EXEC. Now DarkForcesTeam's latest rom has no broblems with my phone so I currently use it.

No one can answer this question for you, you need to try different ones and find out the best for your PPC.

Signal lost, this might help...

Hi there nunu,

I had the same problem, went back to the store and nope not a known problem.... So I started to troubleshoot this

1. normal G connection

2. 3G appears or even H

3. signal lost and after 30 sec. the cycle starts again.:confused:

what worked for me was the changing the of the radio version. I am currently in the Netherlands and here the NEON_Radio_Only_1.65.24.36 works fine, I confirmed it by loading a rom with a different radio in it and the result was again the same.

hope this helped in any way...

Major problem --

I have been travelling round the world for a year and have the same problem, Have tried many radios, if I use 3G( wscdma) or auto band then the signal drops everytime i try to make a call, and no data is possible however if I use gsm only data and voice work fine, thease symptoms are on many networks, Chile, Easter Island,Tahiti, NZ, Fiji, Optus ( OZ ), and m1 ( singapore ),

Radios tried

EMO 1.71.09.01

Neon 1.65.24.36

1.65.21.18 ( att )

I even loaded the generic dopod rom + radio and it didnt seem to help.

Is it possible something low level has changed whilst doing all this flashing ?

Or could the Hard SPL affect something.

I always try to buy a 3G USIM in each country and test the sim in a backup G800 to ensure the carrier has enabled 3g data okay.

Phone is Kaiser ( HTC TytnII )

ROM is varied but and usually lorentis series roms -- L26 12 light atm

Symptoms, 3G icon shows but data wont connect, if you try to call radio strength bar drops to zero and cell communications are lost , sometimes reestablishes comms but often needs soft reset to band switch to work.

If 3G icon not showing all calls and GPRS data works Okay.

Personally I would not expect this to be a hardware failiure as many others are experiencing teh same fault and for working hardware to fail in use is more erratic in the failiure mode, but a low level register, or some other type of protocol corruption could easiliy be the cause......

The proven "high GPS current consumption in standby" issue is also present as it seems to be on all Kaisers but afaik the root cause of this was never resolved either .....

I have the same problem. Already had it with WM6.0 original HTC ROM (Finnish ROM, but language set to English). Then sent it to service. It came back, they said they "reapplied software or smth" and it worked after that. Then after 6.1 update again, the same problem (even with the latest updated Radio ROM).

When I set band selection to auto, it picks up 3G or even H but tends to loose it and definetly looses connection to network if I try to make a call. Can't take any incoming calls either.

It works ok when I force it to use GSM (EDGE for data) on Band selection tab, in phone properties.

I probably won't bother taking it to service anymore cause there is no local service here in Estonia, they ship it to Finland and it will take a minimum of 3 weeks...

... so I'm waiting for Xperia X1 and hope it's not as much HTC.

Hardware problem, repair needed and unavoidable to get 3G functionality back.
[Tilt, TyTN II, MDA Vario III General] stooby:
I have the same problem.

I bought an O2 Stellar (Kaiser) from a work colleague and it worked fine on 3G/Auto on the day I bought it.

The next morning, when I switched on the phone, it had exactly the symptoms described (i.e. it would only work if forced into GSM mode).

My colleague took it back to O2 under warranty.

1 week later, it was returned as 'fixed', but it actually still had the problem, so my colleague returned it again to O2.

Another week later, O2 provided a replacement unit under warranty.

The replacement worked fine, until the next morning when I turned on the phone and had to force it into GSM mode again because it wouldn't work in 3G/Auto mode.

I'm on 3 in the UK and I suspect the problem is something to do with the roaming onto Orange GSM which happens when there is no 3G signal from 3UK. However, on the day each of the units worked, it was switching between 3G and GSM repeatedly because the 3G signal is fairly poor in my office.

I'm now waiting for my colleague to return from his holiday so that he can return this unit to O2 and we'll see if we get another replacement. If we do, I'm very reluctant to actually use it - I think I'll probably just sell it on and get something different. Shame because I really like the Kaiser.
