Bootloop

Hi, everyone. I unlocked my phone through this way and ı had install Steadfaster's own v29a rom, kernel whatever ı have been using normally but ı had flash titan kernel without flash baseband and now ı have a bootloop issue. There is a solution specifically for what in state of mine. I didn't take any backup before flash. Phone: H815(tr) Rollback:0... IF English bad sorry to anyone who cares. Note: I'm not advanced user or in this forum not even regular one so ı'm just copy-paster and may we call cautious courageous...-Yeah, anyway ı did break up the phone. (Yaşamasın kötülük)

...

It's fixed when ı'd flashed last rom posted by WiZaRd891 thas rom has Titan kernel...

Thanks for the reply!

However with this Stock Rom my sim card is not detected. The message is "Service is disabled"

When I flash Lineage Rom everything is fine. Any Ideas WHY???
[G4 General] LukeSlovian:
Hello to all users of this forum. I warmly welcome the Honorable Recognized Developer steadfasterX.

I am asking you with a very sincere request for help and technical support.

Yesterday I've packed my smartphone LG G4 H815 LineageOS 15.1. According to the instruction.

After uploading the system, I have rooted the smartphone, by recovering TWRP in this configuration:

First I was flashing the SuperSU package with this one > BETA-SuperSU-v2.67-20160121175247

And right after I finished flashing the first packet, I was flashing a packet with Super SU, newer version> And right after I finished flashing the first packet, I was flashing a packet with Super SU, newer version> SR5-SuperSU-v2.82-SR5-20171001224502

After finishing the SuperSU flashing, by recovery TWRP, the LineageOS 15.1 system started successfully. After launching the LineageOS 15.1 system, I reinstalled Super SU, to the Super SU 2.82 Pro version, from the Android Desktop level - not via TWRP Recovery. Then I received a message saying that you need to update the binary files in the SuperSU application. So I did that, also from the level of the lucky LineageOS 15.1 system. After finishing the flashing of binary files, the SuperSU application displayed a message about successful binary files update. Then there was a message with a recommendation to restart the device, so I did.

And from now my newly uploaded system LineageOS 15.1 has a problem to load from the Lineage animation boot to the LineageOS 15.1 Android Oreo 8.1.0 desktop. I am asking you with very cordial request for your technical support.

Sincerely LukeSlovian
[G4 General] nenich78:
Problem solved!

With the Stock Rom mentioned above use this kernel

" h815_stock_boot_build-8-nougat"
[G4 General] LukeSlovian:
Hello, I am addressing you with a very sincere request for your support. Due to the fact that in LineageOS 15.1 I had complications with the correct launch of the GSM module - despite the correct insertion of the sim card, to the SIM card slot, when the LineageOS 15.1 is activated, the icon from the range is not active for a long time. Therefore, I decided to return to LineageOS 14.1 Android 7.1.2 Nougat.

Dear Forum Users, as recommended by one person from the forum, I tried to flash the Root application in LineageOS 14.1 with the Magisk Mask application in LineageOS 14.1 Android Nugat 7.1.2, however, TWRP recovery tells me that the flashing process from the zip package is not possible to run, details on the video>

https://photos.app.goo.gl/fYJ7d2dx77QQaVjE9

Dear users, I am currently using LineageOS 14.1 Android Nougat 7.1.2 but as I would like to go step by step to LineageOS 15.1Android Oreo 8.1.0 then I will be very happy. However, currently I have here in Android Nugat 7.1.2 trouble with running Flashing Magisk Mask v19 zip

Due to the fact that currently I have trouble with the correct start of flashing the zip package Magisk Mask v19 I am asking you with a very hearty request for your support.

It informs that after the restoration of LineageOS 14.1 Android Nougat 7.1.2 by TWRP recovery I removed the Super SU application manually from the desktop, thinking that I could replace the problematic Super SU on Magisk MasTWRP

Flashing the Magisk Mask v19 zip application works successfully on LineageOS 15.1 Android Oreo 8.1.0. Yes, if I manually remove Super SU in Oreo 8.1.0, flashing Magisk Mask v19 zip works successfully through recovery TWRP

In connection with the problem described above, I am asking you with a very cordial request for your support in the subject.

I am asking for your technical support. Sincerley, Luke

Hello!

Need some assistance again D:.

After installing this H815-ONLY_ARB-0_v29a_FULL-STOCK-ROM_UsU, I have found hard to root it.

Tried Super Su from Google play, but it said :"Root undetected". Then tried to flash it via TWRP, but then the Rom did not load.

Then flashed Magisk via TWRP, but when check the root it said "Not rooted".

Please give me some idea where I go wrong!
[G4 General] steadfasterX:
Supersu is unsupported .

Either use the lineageos root add-on (!) or magisk . Magisk is known to have that described issue on several devices and ROMs (even stock) . to fix: flash magisk reboot to android , reboot to TWRP , flash magisk again , reboot to android. Should work now. If not repeat .

Please keep the stuff in the correct threads (This is not UsU related)
[G4 General] Prayerwimp:
Hello and thank you for all you have done to bring this about. I have gotten to the point at which I installed the OS then I restart and the phone just loads to the LG screen and no OS. I have a LG VS986. I have tried to load it twice to no avail. I can get to the TWRP screen. Please help me with the next step. Thanks. Also now that I have it rooted do I still need to go into Linux to flash the OS, Google apps, etc?

Successfully Unlock F500K , i have now stock marshmallow rom installed f500k20t , i want to know that can i upgrade it to nougat through lgup ?

and THANK YOU SO MUCH FOR YOUR EFFORTS <3
[G4 General] steadfasterX:
Really ? I mean..... REALLY ? Do you really ask that ? Read the OP again .. And again and again until you got it.
[G4 General] sdembiske:
NO ... ! Suggest you re-read the OP, carefully this time - in particular FAQ 2a) & 2b). You upgrade by flashing a rom for your particular device/GPT compatability with the latest preview version of TWRP for the rom version you are flashing. You will find a UsU flashable rom for Nougat (stock or custom) in the Downloads section in the OP (recommended to stick to them in order to avoid problems) - do a

clean

flash in TWRP (wipe Cache, Dalvik cache, System and importantly,

format

Data), of whatever rom you choose. Backup your data first and do a TWRP backup of your current MM rom installation before proceeding to flash a new rom.
[G4 General] pchacker47:
Sorry mate i did'nt mean to shock you , actually i am new to android development and i read it but i have confusion that's why i ask , sorry for my dumb questions , and i want to say that THANK YOU SO MUCH FOR YOUR EFFORTS <3 YOU'RE A LEGEND !

[G4 General] adam_s_459_:
So in the OP (or FAQ) it says that there is an option in salt to flash kdz, but there is also LG UP. I know that LG UP will hard brick but if I flash that same kdz in SALT it will still brick correct? Or does it just not flash the partition(s) that brick the device?
[G4 General] sdembiske:
Your question should really have been put in the SALT thread.

From the SALT OP:

In development (already working on LP firmware!

NOT

on MM or N! read the Note):

Flashing a folder (e.g. from a previous backup)

* Flashing a KDZ*

i.e., not quite ready for prime time ...
[G4 General] kmmng:
Hi,

I have used UsU to unlock H815L Israel version.

The unlock itself is working fine, but after unlock I have problems with modem crashes (com.android.phone crashes all the time). I have flashed UsU baseband, this won't help. I have flashed different versions of full modem partition of Lollipop, either from H815L backup or from European H815, this also won't help. And I cannot flash UsU kernel, as there is no kernel for stock Marshmallow.

Stock Lollipop - seems to work fine, but I don't want to run old Android version.

Stock Marshmallow - modem crashes, only if SIM card inside.

Stock Nougat - modem crashes with SIM card inside. Using UsU kernel seems to work, but after a few days of use, phone crashes and bootloops and only data wipe helps. I don't know if the problem is in the kernel or in the ROM.

Custom AOSP based ROMs with UsU kernel - works, but there are some unrelated problems with them so I don't want (yet) to use them.

I have tried to isolate the kernel patch from sources, and apply it to stock H815L kernel source for Marshmallow, then compile my custom kernel. This seems to solve the modem crashes, but bluetooth still wasn't working and maybe there were another issues I don't remember now. So maybe I'm not applying the patch correctly, or not compiling it correctly.

It would be very good if you could provide stock Marshmallow kernel, preferably based on H815L sources without any modification, or give me instructions how to patch and compile it right.

Thank you.
[G4 General] Bcoates84:
Re read the O.P.

Do a clean flash.
[G4 General] kmmng:
What do you mean clean flash?

I have flashed everything from the beginning multiple times, wiping data even more times, and all this on two different H815L devices, all with the same result. What am I missing?
[G4 General] Sir Daniel III:
Um, clean flash means you wipe cache, dalvik cache, data, and system. Then you flash whatever ROM you want, etc.
[G4 General] steadfasterX:
The custom AOSP based UsU ROMs (with a CLEAN modem partition!) or those for h815/h811 but with the UsU baseband flashed are working fine afaik. Oreo is great but use Nougat when you depend on bluetooth voice. Our custom ROMs are more stable and battery friendly then stock IMHO...

Share your kernel sources on github/gitlab and the changes you applied. I may can take a look at it.

When you flash your own kernel you may need to flash the kernel modules as well when bluetooth isn't working. Does WiFi work on your custom kernel?

I won't have the time to build a h815 mm kernel in the near future sorry.

[G4 General] steadfasterX:
so here it is.. the real & fixed fix for low video framerates on UsU'd devices.

sorry again for any inconvenience and those who got a heart attack after applying the first version of that patch (broke cell service, camera and more).

This patch is needed only for those who are willing to take a risk and who are able to read instructions thoroughly.

Flashing that patch will change how you flash ROMs afterwards and it may break things nobody knows (yet). It will blow / trigger a qfuse different but similiar to the ARB one though (details in the README).

You know it, of course: flashing things is always a risk even when we all are so used to the fact it goes well - most of the times.

We see the warnings when flashing but as it is written everywhere we ignore or simply do not want believe them.

Like: "It went fine the last billion times so why should it fail

now

?"

This whole thing here showing me (and I guess you) again how risky it is especially when working with vendors like Verizon, Sprint and such who makes heavy use of locking down android phones.

(Funny enough that exactly one of these(!) OEMs who are trying to tie up his customers makes UsU possible at the end.. lol.. )

ok here are the instructions: follow them briefly and you will/should (hopefully) have your full framerate performance back: https://github.com/Suicide-Squirrel/issues_oreo/issues/11#issuecomment-483691424

.. but do this only when you can take the risk and disadvantages this patch has (check README).

The above has been tested by 3 persons, me (h815 - UsU'd), thsachs (h815 - official unlocked) and [MENTION=6302635]sdembiske[/MENTION] (H812 - UsU'd).

Thanks again dudes.

if you had read the instructions and so the README.txt you will find that flashing this will increase another qfuse to make your device working again. qfuses cannot be reverted so again:

DO THIS AT YOUR OWN RISK !

:p

As you can read there this patch should work for any UsU'd g4 model but .. we all are aware again that flashing is a risk - always.

and last but not least and before you may ask:

This patch will never find its way into my LOS builds as it increases qfuse levels which should be IMHO a user decision.

Even when this fixes an issue with the UsU implementation I am not willing to take that decision. In general an UsU'd device works fine

without

that patch.

If a user thinks he needs this fix he must apply it

manually

. Over and out :)

[G4 General] kmmng:
This is exactly what I did multiple times, but it doesn't help as the problem is somewhere else.

---------- Post added at 09:04 PM ---------- Previous post was at 08:42 PM ----------

I will eventually switch to AOSP-based ROM but for now I need the option to have stock MM working.

I tried to flash kernel modules to /system/lib/modules but this didn't help me with bluetooth. I will check about wifi and all other things in a few days.
[G4 General] Vishnuisgod:
hello gents;

I recently started using my G4. First time, my g3 suffered a catastrophic screen breakage. I had put a sim card in it, and I was trying to get my google account loaded but my contacts werent updating (over several days). As I dont have full access to the www, I had limited time to search for answers. The one answer I found was to do a factory reset. I was kind of desperate, so I did..... Now all my wifi passwords wont update/work. Im presuming something went wonky with the data transfer, Im on a ship in the arctic.... Its frustrating to go back to IT support everytime Im in a wifi different zone. As my g3 had about 4.5 years worth of wifi passwords, all I can find seems to say its in a locked folder I can only access via rooting.

My question is this; do I need to go through the whole unlocking and rooting process or just the rooting? I still on stock MM. Yes Ive UsU'd. If I just re-root. Could you please direct me to the proper guide, I know I cant use LG UP, etc anymore.

best regards from the Bering sea

[G4 General] steadfasterX:
Well this thread is about UsU not about how to migrate from another device to the g4.. But here is a quick reply anyways :

Unlocking and TWRP is enough usually as you can access all your data by TWRP then.

/data/misc/wifi/ should usually contain what you need but keep in mind that this might be incompatible from ROM to ROM and between devices.

The other option is to even root and let titanium backup do its job (their you can backup your access points as XML which should ... be compatible with other ROMs. Still no guarantees for between devices though).

I would suggest to Google around for other guides maybe there is a better solution but not in this thread . Good luck ...
[G4 General] sdembiske:
Enhancing battery performance. Things over a number of years I have found to actually help.

I run both Amplify and Greenify, free on Play Store. Both require root to maximize the benefits and to further enhance battery performance, Xposed (required by Amplify but optional on Greenify - recommended to allow further settings to enhance).

In addition, install these two modules in Magisk -- Greenify4Magisk (while thread indicates deprecated, it is still functional & updated to end of 2018 - make sure you have enabled root mode in Greenify before installing this module) and Enable Doze for GMS Magisk Module.

In your phone's Settings > Security & Privacy > Trust > Privacy guard (

Note

: not all rom versions may have incorporated this Lineage feature & in that case, if on Nougat or lower, look at AppOpsXposed (Post # 873), to obtain similar features) -- in Privacy Guard click on the 3 vertical dot menu at top right of the screen > Advanced > scroll over to Device and turn off the Keep Awake setting in Google Play Services & Google Services Framework and on all your User apps that you do not need to be active at all times - also turn off Start at Boot & Run in background on those User apps that you do not need instant access to on boot-up etc. There is no impact to their functioning when you need to actually use them.
[G4 General] Bcoates84:
- do a clean flash in TWRP (wipe Cache, Dalvik cache, System and importantly, format Data), of whatever rom you choose. Backup your data first and do a TWRP backup of your current MM rom installation before proceeding to flash a new rom.

[G4 General] fates13:
I'm having call issues on VS986 but I never flashed the bootloader, only the full lollipop modem. I think there's just a specific issue with Verizon CDMA phones and H811 rom compatibility.
[G4 General] slim902:
#5 under Limitations/Known Issues in the op covers this. You have to open the rom zip and remove the "assert" line in the update script.

I also have an H812 and installed asocp using this method.
[G4 General] nummer:
So i want to flash RR 7.1.2 rom (meant for h811) and this is what i do:

1. remove assert line at top inside rom zip so it will let me install (bc i am on koodo h812)

2. Boot to recovery and wipe system/dalvik/cache/data

3. Flash RR/gapps/supersu

Now here id the part where i get confused. Which zips do i need to flash for everything to work properly?

-G4_29a_N_modem_UsU.zip

-H812_UsU_baseband_flash-in-twrp.zip

-G4_ARB-0_29a_bootloader_UsU.

I did not flash the boatloader stack and I cannot get calls on my h812 with the nougat Rom.

Read the FAQ m8:

13) I want to flash a custom ROM but I can't!!! It says "This ROM is for device xxxx but this device is >.< !! You told that I can flash any ROM so whats wrong here?

I wrote it in the LIMITATIONS/KNOWN ISSUES topic of the OP but here again:

Taken from the OP:

Quote:

5) If a ROM has no active developer or the developer has not made it UsU compatible you may need to open the ROM zip file on your PC and change the update-script within (just remove the assert line at the top is enough)

edit***nvm figured it out lol

Edit** cant get any roms to boot. Get a black screen with the blue light on. I can flash the stock 29a rom thats in this thread and it works and boots up fine except i have no cell service. Doesnt read sim. Am i doing something wrong?
[G4 General] doomanix:
Successfully UsU'd my main H812 G4 (hoping to replace the mainboard on my bootlooping one) and installed Nougat. Like a few other people here I've got a problem with cell service not working on the phone after install. Followed the instructions:

Flashed UsU = Success

Flashed TWRP = Success

Flashed G4_29a_N_modem_UsU.zip = Success

Flashed H812_UsU_baseband_flash-in-twrp.zip = Success

Then proceeded to flash G4_ARB-0_v29a_FULL-STOCK-ROM_UsU.zip = Success

After booting however I can't get cell service to work. I have not flashed the bootloader stack and won't as to SteadfasterX's previous post. I've tried various combinations of flashing each such as the ROM before the modem and H812 Baseband or the Modem, ROM, Baseband but still no service. I'm on Wind if that helps at all and I'll post a picture of my Software Info screen.

Thanks for any help.

[G4 General] slim902:
I also have a H812 (Koodo) and I had the same problem: i flashed G4_29a_N_modem_UsU.zip, flashed H812_UsU_baseband_flash-in-twrp.zip, then flashed asocp oreo rom and was not getting cell service. I then flashed the modem and baseband again (the same ones i flashed before the rom) and then cell service worked.

Im having issues with no sound and maybe flashing those two things again caused this, but cell service is working.
[G4 General] grantdb:
So happy with my unlocked stock MM H812 rooted custom kernel (stock based) and will be going with stock N next and want to be sure of the steps before I mess anything up!

So what I need to do is:

1) Flash the above stock rom and remain in TWRP

2) ‎Flash my baseband (H812_UsU_baseband_flash-in-twrp) and remain in TWRP

3) ‎Reboot device directly back to recovery again

4) ‎Reboot device

I don't need to flash any modem or N bootloader or anything else. I don't need to factory reset or do any wipe in TWRP before or after the above steps.

Is this correct? Anything missing?

I don't want to be one the people having problems I want to be sure BEFORE instead of trying to fix after!

Thank you!

EDIT: After reading all the posts I'm sticking with my stock MM for a while. Just being rooted gives me lots to play with until things get figured out. Good luck to everyone!
[G4 General] Makifylmz:
Hi again [MENTION=5545101]steadfasterX[/MENTION] I've unlocked my device thanks to you. But during the process i've trouble with laf and rawres files. Salt flashed successfully aboot file but can't make it with the laf and rawres file. So i follow the instructions. Salt get me into fastboot mode and manually flashed laf and rawres file. After that salt wanted to during fastboot mode "push volume up until download mode shows up" but download mode did'nt show up. So i pulled out battery and cable and put back all in with pressing volume up. Boom download mode showed up. Continue the progress salt said unlock succesfull. Than i took breathe after that message :D All fine now.

" https://bpaste.net/show/46a4f4d5682c " This is my error log.

I installed stock nougat zip. That works fine too until supersu. When I flashed SuperSU my imei and ofc cell gone. Before that everything was fine. The other "issue" or "missing" thing is VoLTE support. My carrier supports VoLTE and I'm already using it before installing stock nougat zip. ( Before that I was using the tot one for my H815-TR known as H815-TUR ). I'm going to re-flash stock nougat zip again. Let's see what will happen.

Update 1 : Flashing stock nougat zip solved the cell problem. Of course without supersu. I will try magisk.

Update 2: Succesfully flashed magisk and cell failed again. I've waited 1 minute and cell comes back again !! So magisk works !! BUT everytime when i reboot my device, i need to wait 1 min to cell get work.

Update 3: I've installed viper4android with that way. Install magisk, busybox and I've used The SELinux Switch app to set kernel permissive. After these installations i can able to get viper4android work.

Secret menu ARB Version says = "Versions are different! APPSBL(LK):2, SBL1:0 , TZ:0, RPM:0" What does it mean ? It was "0" before these process.
