Two questions ( fastboot, sound ) GT 540

1. Where is stored fastboot? We can erase cache, system, boot, userdata, but phone still boots with fastboot. So where is stored that part, and how to delete it?
2. How to disable step up of sound in incoming call? What I need to edit, what file?
I sow that 2.3 has this option but where to find it in 2.1?

Fastboot stored in bootloader and for removing it you should flash originar LGs roms via KDZ. You can not remove it without reflashing.

You can remove it, but when an original ROM is flashed, you will be stuck at the LG screen and if you want to get it working again you must flash a Fastboot ROM again.

And how to solve that? I would like to revert to original state ( if it is possible), so I would like to flash with original rom.
Any suggestion?

Still trying, huh?
Why do you need to remove fastboot? You only know it's there if you boot with camera pressed and it doesn't take up any space. Really, it's supposed to be there it's just that LG disable it on their phones and that is wrong of them - it's a valuable part of the Android platform.

If you have fastboot then the chances of bricking your phone are lower.

I just try to find way to erase fastboot, and got chnace to flash LG 540 with original firmware. Nothing more, nothing less. And now, LG 540 is "old phone" but still there is no valid answer

You cannot erase fastboot once flashed, well you can but your phone will stick at the LG Screen, thats what I said before.

So , that is final state: no back to orginal roms after fastboot flash. I searching and found that GOLD CARD can do anything with Android, that is last solution.

I thought the goldcard was used on HTC phones to flash custom RUU files (Rom Update Utility) I'm not sure if it will have an affect on our phones, I could be wrong, I'm not sure...
Also, when you flash a Fastboot KDZ, It still flashes Stock Android 2.1 software. So if you want to use stock OS, just re-flash your KDZ.

You are kidding, right?

And what is wrong with that? You can still use Android 2.1 and Fastboot ROM, it's just like flashing a regular update, except you now have the Fastboot function

From my experience, u can remove fastboot by flashing original 2.1 rom from LG. There are things u need to do 1st.
I don't think u can't flash directly to original 2.1 with kdz updater from 2.2 or 2.3 custom rom. Flash to custom/backup 2.1 first using recovery (note that u need older recovery)
Then using that 2.1, flash original 2.1 rom from LG. Note the rom versions (v20d/b/a) I don't think u can flash to lower version. Once I've v20b with fastboot then I flashed v20a original, I got Linux Kernel Panic. Thankfully LG service center can fix that. I can flash v20b with fastboot to original v20b n the fastboot is gone (press cam + power, nothing happened)
I did that when I had problem with my screen, n need to go to service centre.

I try that 50 times: and always get same result: flash with stock firmware, and stuck at LG logo. I can use any fastboot rom, but cannot use original rom.

Beats me. It worked for me some months ago. What version of ur original rom and version with fastboot? Mine are v20b both. Try this: when u have custom 2.1 rom installed via recovery, try flash 2.1 rom with fastboot via kdz updater. Then try flash original 2.1 rom with kdz. Flashing with kdz updater when ur phone is in download mode might help, so try that too.
If that won't work, keep ur stuck in LG logo phone to service center. Just say when u try to update online, it became like that. They'll flash the original 2.1 rom without fastboot in 15 mins.

Thats very strange I could not get back on original ROM for the life of me I'm probably doing something wrong, This is me who bricked my phone -.-
Jack

i think to get back to complete stock no fastboot etc you need to flash a 2.1 backup via fastboot or recovery then use kdz to flash a complete stock rom but im not to sure on that one

Any link?
I try:
flash with KDZ ( any of stock rom)
repair option in LG tool
using out.kdz ( as someone suggested) then stock rom
using other modes in KDZ updater CS and CS Emergency
It looks like 90% of LG GT540 cannot flash with stock rom once fastboot rom is used, and like 10% can do this.

Need help, urgent

Hi, I have a D806 G2 and I have a big problem.
After an error modifying my build.prop I was left with a broken phone. It wouldn't boot to the os.
I was rooted and with TWRP so I restarded and tried to revert to the old build.prop (that's the only backup I had) and it didn't work.
I followed the tutorials to go back to stock (I had done it once before to update my phone while rooted, but that time the phone was working fine).
Well, to my surprise, given that I only had recovery or download mode, the process started but failed with an error.
Now, I don't have a System, meaning that my system folder is empty so I really don't have an os in the phone, and all procedures to flash a rom, fail.
I have tried flashtools and everyother tool but nothing, can't put a rom in the phone.
Now I'm kinda desperated because It is too expensive for me to loose the phone (things in Argentina are far too expensive) and when I put it in download mode it clearly says ROOTED so I will have a problem with guaranty.
Please, someone give me a hand!!

Can you still get to TWRP (recovery)? Which version of TWRP are you using? Do you still have the zip file of the ROM you're on?

Sorry was too crazy to post most data.
No I don't have a backup of my rom, but I got a backup from another phone and it doesn't work
Gladly I could use a USB OTG to copy Carbon and Gapps to the phone and I could install that so the phone is working now.
The problem is going back to stock because I would need a backup of a D806 rom and I don't have one.
I'm on TWRP 2.6.3.4 and it's working fine now. Thank you very much.,

Very simple and very lucky you still can access download mode. Just using flashtools to flash TOT again then its all go back to original stock.

I would if I could, but my IMEI reads 0, hence no luck with LG software.
Luckily I could boot the phone to an AOSP rom (copied via USB OTG to my phone -I still have recovery-)
So, I have an AOSP rom, I can get a backup of a similar rom to my stock rom -from a user in another forum- and I can install that backup (foing it ATM)
BUT, my IMEI is 0 so LG software doesn't fully recognize my rom and drivers don't fully install
HELP??

Stuck in recovery after OTA but stupidly formatted SD card...need help please!

Hi all,
I have an LG D802, was running standard ROM just rooted and with PhilZ recovery. Well I was silly and tried an OTA update, and got stuck at recovery...unfortunately I panicked, cleared everything and tried to flash another ROM but I'm still stuck at recovery.
I tried the instructions in the thread about being stuck after an OTA update but as I;ve formatted the sd partition it didn't work.
I want to go back to stock, I just have no idea how....I have ADB access though if that helps! I'm not really experienced in this kind of thing so please dumb it down for me!
Any help much appreciated!

can you get into download mode either try the adb reboot download mode or turn phone entirely off and hold volume up(only volume up) and plug it into the pc usb, if you can use the back to stock guide to get your phone working again

Yes trued flashing a custom ROM, however in my haste to try and stop the OTA forcing me to recovery I may have formatted some partitions I shouldnt have.
Can I restore everything by downloading the kdz with all the correct IMG files in, converting to a flash able zip (saw a guide on here) and trying that?

VS995 boot loop into TWRP

I followed the root instructions to the letter and now I'm stuck in a boot loop that continually just goes into TWRP. I've down the format data/reflash SuperSU more than once and it doesn't help. Any ideas?

Did that and still reboots into TWRP. I tried reflashing my ROM and when it finished installing it tried to unmount system and it said failed; no such volume. Could that be the issue?

Only way I fixed this for me was to restore to stock using kdz. I was able to hold volume up with the battery out, plug it in. Kdz ran from there

That's what I was afraid of. Which program did you use to flash the KDZ file? I tried LGUP but I just get errors.

Have to use Uppercut. LGUp won't work because the model of the kdz won't match the dev bootloader from Dirty Santa I think. There's a few restore threads you should be able to get the link from there

it's very easy, and you have to go out there to find a kdz file for your phone.
if your windows defender is working, disable it.

Returning to Stock

I just got this phone and I'm debating on unlocking the bootloader and rooting it and I was just curious if in the future I need to return it to stock (especially for selling it in the future) how do you go about doing that? Do you just flash one of the stock firmwares though TWRP like I found here? http://downloads.codefi.re/autoprime/LG/LG_G6/US997/US997-USA/US99714a
Then what do you do if that is correct? Also how do you relock the bootloader? I'm sorry if these are noob questions but I have been out of the modding game for a good while.

Just flash a kdz trough LGup and the phone will be completely stock, no twrp and no root. Then you have to only lock the bootloader by typing "fastboot oem lock". Don't run this command while you have twrp and root!
Ah, and the fact you have relocked the bootloader doesn't mean that you recovered the manufacturer warranty, LG can easily verify if you used the unlock bin.

Also just to be clear I unlock my bootloader, install TWRP and root the phone. If I ever want to go back to stock for selling the phone or whatever I just download the latest KDZ file like I linked to above and then I flash it to the phone and it will return everything back to stock? Then after that you just do the relock command and the bootloader is closed again?
I appreciate your help. I just to be super clear.

Pretty much yes, search for uppercut if you have driver problems with LGup, and for firmwares this is the best site to download them: https://lg-firmwares.com/lg-h870-firmwares/

Ok then

LGUP
Hi, so I started flashing the kdz on my LG G6 using LGUP and it starts, but then randomly quits out. It's recognising my device and the file is definitely the correct one. Any hints as to why it's not working?
EDIT: I managed to fix it, apparently Windows Defender was seeing Uppercut as a virus and stopping it from creating the files it needed to. So make sure you turn off Windows Defender when you do this.

My experience with returning phone to stock is bad. First unlocked bootloader, installed twrp, bootloader for havoc ROM and ROM itself..
Havoc 3.1 OK, but BT calling not working, so I decide go back to stock.
LGUP used without problem, but then camera neither flash ligh doesnt work anymore.
Last firmware for H870 used from official.
Have someone same shi t experience like me?
Trying everything, but no success.
So its not easy go back to stock again..
(My phone is H870 for EU)

It's a known problem, the A10 ROMs somehow mess with files needed for stock camera that aren't included in stock pie.
You have to flash Oreo bootloader and then 30b zip for the camera to work.
If that doesn't work flash Oreo kdz and update to Pie.

Problem finally solved!
Tried many times flash Oreo bootloader and then 30b(pie), 20a (oreo). With 30b everythings work except camera. With oreo 20a phone wasnt even bootup normally.. (after reset just screen with green android and message "No commands" appear. I used LG UP 1.14 with Uppercut.
Then after many unsuccesses I put phone to state where bootloop appeared and I thought about to throw it into garbage.
ADB shell and TWRP saved me... I was again able flash roms.
At the end I found some package with LG UP 1.14 and patch (so I could use it without Uppercut...there is a new LGUP_common DLL), and with this combination flash procedure worked smoothly.
BUT! I had to load nougat stock rom first (H87011i_00_OPEN_EU_OP_0108.kdz), which fix partitions in phone somehow (but there wasnt possibility upgrade higher). Everything, camera included was working with this rom..
Then I flash oreo stock rom (H87020a_00_OPEN_EU_OP_0423.kdz), and now It booted right (no "no command" during startup). Phone worked perfectly, and I used OTA upgrade to land on 30b pie last official update.. tadaaa
Hope it will help others with same problem..
