Phone blocked at login no recovery mode

Hello,

my lg is locked at login with the secure booting error,i followed the procedure so,full wipe and install the rom 3.1.

I come from cloudy G2 3.3,the problem is that i cannot go into recovery mode...i follow the procedure but the phone goes into a mode where i can only chose to factory reset...i have installer TWRP.

Can anybody help?

Thanks.
[G2 Android Development] rtorres0106:
Just continue to factory reset it will just go to your recovery mode.
[G2 Android Development] mark745:
Takes over 3 hours to charge where it usually takes just over 1. Data speeds are also really slow. Can't find a solution to these problems. Can you tell me when the next update is please, or if there's a possible solution through modding or apps.

Having some problem, just flashed yesterdfay AospExtended V3.1 [OMS/DUI][2017/01/23]

First one I've flashed on LG2.

Cellular Data do not work. Wi-fi has no prolems - all is good. but in Cellular I cannot connect to Internet.

I've tried to switch LTE / 3G / 2G, make network connections from start - no use.

Someone else also has problems ?

EDIT:

Sorry !! It is problems with my mobile operator ! unluckily it is happening from the time I've flashed ROM :)
[G2 Android Development] simon92g:
I finally managed to flash bumpboot and installing this rom,there was a notification wich suggested to install superSU so i installed it by TWRP,the device will next reboot with the secure boot error again,i reflashed bumpboot and it went ok...

Now i have used the new rom for about an hour and i have already had 4 complete locking of the device,i had reboot it by pressing the power button for long time and supersu still says it's not installed.

What can be the cause?
[G2 Android Development] prokoppd:
SMS notification

I have a problem. They do not work for SMS notifications, and no sound when you receive an SMS. SMS senders when the icon is in silent mode. Why?

I'm going to see if I can get my att still going on this ROM. Can't seem to get data working on anything.
[G2 Android Development] bobgeneric:
I did flash another ROM.
[G2 Android Development] jrk190:
I also found that if you've got a stock flashable ROM, you can do the following:

Wipe system, data, caches

Flash stock ROM

Boot

Reboot to recovery

Back up /boot partition (go ahead and do efs and model just for the heck of it)

Flash the ROM and any zips you like

Flash boot bump

Hope your phone doesn't explode.

If you ever get the secure boot error again, you'll have your /boot backup in TWRP that you can restore.
[G2 Android Development] tubnik:
I really like your ROM and I'm going to upgrade to the new version soon.

The only thing that really bugs me so far is that USB audio is unsupported. Will it be fixed soon?

[G2 Android Development] simon92g:
Go back to page 35 of this forum,there is a post by jneto3000 with instructions and link where to download bumpboot,you have to wipe,flash the rom,flash the bumpboot and gapps,i was in the same situation and now the rom works just fine!If you can't go to the recovery with the button combination but it brings you to factory reset just click yes,it won't really reset anything but carry you to the recovery.If at the end of the flashing the recovery ask you if u want to install SuperSU,press NO!

I've just read that we have to flash bumpboot to get this rom working. Hell no. Last time I flashed bumpboot I was up all night to apply TOT method to my bricked G2. And I did everything as written.
[G2 Android Development] xb034:
Don't worry, I've just done it on my D802 and works fine
[G2 Android Development] djbaha:
By all means I'm not messing with my boot partition ever again. I don't want to waste hours.
[G2 Android Development] 60nine:
so why are you here then?

if you don't like the basic requirements to flash this rom - then don't do it - simple as that...

don't get me wrong but i bet you bricked your device because of your error only... you obviously missed something or did something wrong...

i've flashed all kind of zips to my device, and bricked it a few times - but only because of my error caused by not clearly reading provided instructions from the developer(s)...

my 2 cents
[G2 Android Development] djbaha:
Well, I did not listen to you guys, and bricked my phone again - boot certificate error with no recovery. Used SRT tool, nuked download mode, and fixed recovery via fastboot. This time I've listened to you guys and flashed bumpboot just after rom. No problems occured, and rom booted successfully. Testing the rom right now, Nougat seems cool.

The other time I bricked my phone, I assure you I did nothing wrong. Followed as written.
[G2 Android Development] 60nine:
it happened to me when i was upgrading from version 3.0 to 3.1 of this rom...

recovery is there, you just have to turn off your phone completely and use the button combination to enter twrp...

turning device off completely:

1. press and hold pwr button for 10+ seconds

2. device will turn off and on, showing lg logo, DO NOT LET THE PWR button off until it shuts off completely

3. only now you can try button combinations to enter twrp (if you fail - go to 1. and try a different button combination)

4. if you succed with the button combination - screen will show white factory reset screen, choose "yes" 3 times to enter twrp (don't worry - you won't delete anything)

when you enter twrp - just flash rom > gapps > bumpboot and voila...

sure - if you have all of this on your device storage or usb/otg stick... (i personally always use usb/otg stick when flashing roms and stuff)
[G2 Android Development] umerzifonlu:
If TWRP has been ınstall before boot error.

Full turn off device

Power+vol down

When you see LG logo

Vol up + vol down

After yes yes...

[G2 Android Development] 60nine:
does anyone else have an issue with dialer app?

phone rings - it takes some 5 seconds for screen to turn on and show who's calling... is this a kernel thing? (maybe something to do with waking device from deep sleep?)

can it be easily fixed? (by changing some settings in Synapse app perhaps)

[G2 Android Development] Immortal0907:

[G2 Android Development] djbaha:
Well, I'm not sure the problem we had was the same but the LG did not stay long enough to allow me to enter recovery, as soon as the logo showed the Error would show too. Anyways I've solved it.
[G2 Android Development] 60nine:
it's because you didn't turn off your phone completely...

there is a difference in reseting your phone by holding pwr button and turning your phone off completely...

turning the phone off requires pwr button to be pressed for a longer time, and in the process, LG logo shows just for a fraction of a second and if you continue to hold pwr button while it happens - the phone will shut off...

(all of this must be done without any usb cables connected to the device)

if i had a dollar for every time i was explaining this on xda :)

nevertheless - i'm glad you solved it...

cheers...

-Wipe Dalvik/Cache;

-Answer n at the twrp su questiton;

-Reboot

but still my g2 won't boot correctly, it just shows the LG logo for a sec or less and then goes black screen. What am i getting wrong?
[G2 Android Development] sh1bby:
If you did everything as explained you wouldn't have a problem mate. Are you on Daniel Stuart's hybrid bootstack to begin with? Are you using the latest TWRP?

[G2 Android Development] 60nine:
wipe system, cache, dalvik

flash rom

flash bump boot zip

flash gapps

clear dalvik & cache

reboot

edit:

flash kernel of your choice only after you succesfully flash the rom that boots...
[G2 Android Development] belgianrebel:
Could be a bootstack issue, search XDA for hybrid bootstack and flash this, then ROM, then gapps, than bump, wipe dalvik and cache and everything should be ok

[G2 Android Development] Lycanlk:
After using the phone with stock based ROMs for about 3 years, I tried this ROM for a change. It was a bit hard to get everything done at once just like flashing a stock based ROM, however once you have done them all, this is much better than any stock based ROM by agreeing that you need to give up some of the stock features.

The ROM is super smooth and far more better performance than the stock also with a good battery life. I had to fully unroot the ROM in order to work with my bank app and to play PokeMon. Unrooting removed my recovery (TWRP) and it flashed stock Nouget recovery instead. That's fine for me until the day I wish to try an update or a new ROM. (You might need SRKTools to to get Recovery back)

Hope the Dev will resolve these flashing issues in later versions.

Anyway thanks all the Devs for this nice ROM!

Waiting patiently for 3.1 for vs980
[G2 Android Development] czajunia:
Just a quick check. Has anything changed installation wise between previous versions and the 3.1? In the past I've never had to flash "bump boot zip" and it all worked perfectly fine. However, after automatically downloading the 3.1 version I followed the exact same installation procedure as always (with full wipe) and was greeted with the "Secure boot failed. Cannot verify boot certification." message afterwards. Which meant I had to reinstall everything from scratch.

Does it mean that "bump boot zip" needs to be installed from now on? Also, where can this be downloaded from?

Many thanks.
[G2 Android Development] 60nine:
i don't know if it's "from now on", but it's required for 3.1...

i also remember it wasn't required when i've updated from 2.0 to 3.0...

nevertheless - it was already explained by the OP few pages back...
[G2 Android Development] freinet:

[G2 Android Development] Tibiti:
If I'm correct all you had to do is dirtyflash the rom zip..

What happened is su installer changed the kernel signature, which in turn said "nope, effed kernel, not using it".. that's the same reason you need the kernel bump.
[G2 Android Development] 60nine:
nope... dirty flashing is not recommended for this rom
[G2 Android Development] Tibiti:
Didn't he just install it clean prior to that!

Coz in that case (only) dirty flash is fine, otherwise not, I know that.
[G2 Android Development] maksakal:
Still Hotspot problem exists. Will there be any solution. Did I miss something about that problem?
[G2 Android Development] 60nine:
ok, a misunderstanding...

yes, he can dirty flash the rom but he must flash the bump boot as well...
[G2 Android Development] Lycanlk:
Just flash the SuperSU latest and open it. In settings you have the options to fully unroot. But if you do that you will lose the recovery. So back up all your stuff first. It is also hard to get back to custom recovery too. Good luck!
[G2 Android Development] czajunia:
Thanks guys. Yes it was a clean install which I normally prefer anyway.

Where can I get a compatible bump boot zip file from? I'd like to avoid trial and error.

Also, as this has been mentioned, I can confirm that HotSpot doesn't work for me either. Not even with 3rd party apps such as Barnacle Wifi Tether. I am getting an error message saying there is no WAN interface to be found.

[G2 Android Development] akkenoth:
I did it! Took me at least 5h to get it done right though :silly:

Disclaimer

I'm not responsible for any data loss, bricked devices (how would you even do that?) nor your cat eating your fishes. Your actions, your responsibility.

As always, DO A FULL BACKUP FIRST.

Dirty flashing

I did it while clean flashing, however the flash script

seems

to support dirty flashing.

Also you can always do a full backup with oandbackup, do a clean flash and then restore it.

Instructions

Removing root from base ROM

Download original ROM's .zip file

Unpack it (preferably to a new folder to keep it cleaner)

Open folder you unpacked it to

Remove supersu directory with all the contents

Navigate to META-INF\com\google\android and open updater-script in your editor of choice (it's a text file)

Remove lines 61 to 64 (their contents, for reference, included below)

Navigate back to ROM's top-level directory (the one containing META-INF and boot.img)

Select all files and pack them into a zip archive

Copy created zip archive to your phone along with Magisk .zip and Blastagator's flashable bump (optionally: GApps installer, I've used pico package from opengapps)

Reboot to recovery

(Recommended but possibly optional) Wipe everything except storage

Flash the created zip file (you may have to disable zip verification in recovery settings!)

(Optional) flash GApps

Reboot to system (will take some time)

Reboot to recovery (option to do so from power menu is enabled by default)

Flash Magisk

Flash cbump

Reboot

Enable magisk hide, busybox hide etc in Magisk settings

Reboot

Profit! See attachment!

Lines to remove from update-script:

ui_print("Flashing SuperSU...");
package_extract_dir("supersu", "/tmp/supersu");
run_program("/sbin/busybox", "unzip", "/tmp/supersu/supersu.zip", "META-INF/com/google/android/*", "-d", "/tmp/supersu");
run_program("/sbin/busybox", "sh", "/tmp/supersu/META-INF/com/google/android/update-binary", "dummy", "1", "/tmp/supersu/supersu.zip");

Additional notes

Magisk script actually supports bump-ing on its own but currently it's LG G2/G3 detection is not working properly (there is a pull request in Magisk repo already). I have flashed a patched version, so I didn't have to use cbump; however the outcome should be exactly the same.

AFAIK it's not currently possible to achieve this without reflashing the ROM, as it flashes SuperSU by default and by that it modifies boot.img populating it with SuperSU's files, so simple scripts like unSU won't work. I managed to get Magisk working and detecting SuperSU earlier, but it won't pass SafetyNet that way.

EDIT: Yes, PokemonGo works!
