I use google trad :(

Hello, since the beginning of installing TWRP 2.8.7.0 3.0.0.0 and now I toujour this time problem I can not solve, and when I make a backup date not corespont!

The bootloader is UNLOCK, I'm on a stock rom the 20D, it is ROOTE and SimpleGX_KERNEL_H81520X_v1.2.6 as kernel.

I'm registered reinstalled everything but impossible to adjust the time :eek::crying::(

Thank you for your answers. :good:
[G4 Original Android Development] bxlegend:
It's a known issue. For now just edit the file name manually.
[G4 Original Android Development] Swizzle82:
Maybe you guys and gals can figure out root for the rest of us! ?
[G4 Original Android Development] hendusoone:
The warranty voiding isn't as bad as y'all make it sound.

In other words: if the defect was not caused by unlocking/custom software, you still have warranty coverage for that defect.
[G4 Original Android Development] the_scotsman:
Good luck with that. Depoends on manufacturer or even the specific dealer, I've seen people get turned away even when the hardware fault has nothing to do with unlocking.
[G4 Original Android Development] hendusoone:
Agreed, it totally depends on the company, but it's sounding like LG is being reasonable about it.

It probably depends on your local laws, too - in the US at least (I know that doesn't help the Euro H815 owners), if the company cannot prove that your software changes directly caused whatever hardware defect you're experiencing, the hardware warranty will still apply. This bit is totally anecdotal, but a few years ago, with my T-mobile G2 (HTC Desire Z), I got full warranty coverage for a keyboard issue, even though the device was S-OFF and running CyanogenMod.
[G4 Original Android Development] wolfgart:
yes ;)
[G4 Original Android Development] somboons:
what's about something lose after unlock bootloader ?
[G4 Original Android Development] IlyaKol:
Magnusson-Moss act. Good to know. I might pull the trigger than when my H815 comes in on thursday...the only thing I can see using my warranty on is something like the hairline crack that the G3's had develops on the G4. I can't see any other issue with the phone software wise that would require warranty service as most of us are techie enough to probably fix it ourselves either via a different ROM, etc.
[G4 Original Android Development] the_scotsman:
Yea, what about DRM breaking - any codecs etc lost that may affect the camera?
[G4 Original Android Development] wolfgart:
is not yet clear. Not clear if you loose DRM partition or is simply hided

In my opinion is fixable....

nothing of that ... ;)

if i open the bootloader will this wipe my device? Where can i download the last or specific supersu.zip ?Thanks in advance

How to install the TWRP?

all methods in 1st post require root?
[G4 Original Android Development] the_scotsman:
Good question actually? :confused:
[G4 Original Android Development] tonyeltriton:
I assume that if you want to flash the twrp you must type "fastboot flash recovery twrp-2.8.6.0-h815.img"
[G4 Original Android Development] the_scotsman:
Yea...the website doesn't list this method. It is how I've always done it with HTC devices. Wasn't sure if it works for the LG too. If that's all I need to do, easy peasy :)
[G4 Original Android Development] NisseGurra:
No luck, getting stuck at "waiting for device"
[G4 Original Android Development] the_scotsman:
I read somewhere you need to install the LG software for it to work. Have you tried "adb device" to see if your computer sees the phone? Did you put it in download mode? Does the device show up in device manager when in this mode?

Going to do mine soon I think.
[G4 Original Android Development] BoneMo:
i think this could help

so question is what is the buttons combination to enter recovery ?
[G4 Original Android Development] NisseGurra:
Ok, TWRP installed:

adb reboot bootloader

fastboot flash recovery twrp-2.8.6.0-h815.img

Enter recovery:

Fastboot boot twrp-2.8.6.0-h815.img

Ahhh: ROOT, NICE :D

[G4 Original Android Development] the-erazer:
i have tried many times to flash twrp... i got a replacement... it is a h815 and ships with v20d... the only thing that works was booting twrp temporary but not the one for h815... only recovery that works ist twrp3.0.0.0h811... now my stock rom is rooted fine but i like to flash candy6 again... i can flash this recovery using flashify but the big problem is if i want to flash candy6 it says this model is not supported because the recovery is h811 and the rom is h815... if i flash twrp for h815 in flashify nothing happens only green robot in recovery... now i dont know how to solve this... i am thinking about downgrading to stock lolipop but i am afraid of a brick
[G4 Original Android Development] MickyFoley:
Did you unlock your bootloader again? Anything standing in the upper left corner whilst booting up your device? Like "Bootloader unlocked" in whitened font? If not, this maybe is the problem. I can only relate it to your replacement and probably the bootloader isn't unlocked on this device.
[G4 Original Android Development] the-erazer:
oh sorry that was the first thing i have done after i getting it:D it is h815 v20d

bootloader is unlocked

twrp starts only temp but only h811

i have done a backup with h811 twrp and after that i wanted to flash c6... done a factory reset and wiped system... bam no system on the phone and twrp rejected to flash c6... kdz over lgup but now v20c...

twrp for h815 even dont want to flash
[G4 Original Android Development] welder73:
Download Twrp Manager from the Play Store and install twrp 2.8.7.0 from it,it's working on my h815 v20d.

And you can also download Quick Boot,to reboot to recovery (twrp) :)

Sent from my LG G4
[G4 Original Android Development] the-erazer:
thanks i will test it and report...

twrp manager reports that it finds no supported recovery for my device...
[G4 Original Android Development] welder73:
Strange...

What's your software version?

Mine is V20d-EUR-XX.

Sent from my LG G4
[G4 Original Android Development] the-erazer:
mine was v20d-262-02 now its v20c-262-02 it is vodafone branded.

my privious device was also vodafone germany no problems since bootloader unlock.

it must be somehow software related...
[G4 Original Android Development] casabato:
Hello everyone. I have a G4 with stock firmware v20d-222-10 (MM), unlocked bootloader, root and TWRP 3.0.0 installed. Until last week, I normally run different nandroid full backups, without excluding anything between Boot, System, System Image, Data, Cache, Recovery, Efs.

Today I tried to perform a Nandroid backup before applying some changes but the procedure aborts with this error: "createTarFork () process ended with ERROR: 255". I did some tests and I found that by excluding the partition "system" backup had a positive outcome. Including "system", the backup aborts with the message that I mentioned. What could have happened? If I try to install the previous version of TWRP the problem could be solved?
[G4 Original Android Development] wartomato:
Hmm, i think not.

Mine errors when trying to backup the system.IMG (md5 error), so i leave that out. Leaving it, the backups are fine.

Compressing the backups is also not a good idea... That's what i found out.

The system image has 4GB. Do you have enough space for this in every backup?
[G4 Original Android Development] casabato:
Hello. I solved!! :o Given that the problem was not the TWRP recovery but the "system" partition I tried to perform another backup of the single "system" which, of course, was canceled. I picked up the log of this execution and I looked for the error message. I found this:

"Error opening: '/ system / app / BluetoothMidiService' (Not a directory) I: Error in Generate_TarList! Error creating backup"

By RootExplorer I found that file (BluetoothMidiService), I copied it on the external SD and I deleted it from the internal SD. I rebooted the phone into recovery, I only backed up the partition "system" and the backup is finished regularly :). Then I ran a full backup, but I didn't run the restore, I'll try later. I tested the bluetooth and it seems to work as usual. I have "associated" a Samsung Galaxy-S4 and I exchanged files (images, movies bervissimi, pertaining to it) from one to another and everything seems to work. Now I ask: what is that file?

On March 13, I remember that I installed a couple of applications (then uninstalled) to try to connect my G4 to one smartwatch (the cost of a few Euros). I used it about a couple of days, to see how it works, but then I removed those applications (notice bluetooth, bluetooth file transfer). It may be a residue or an important file and maybe it is corrupt and should "fix it"?

Today I put back in place the file that I had canceled, giving the correct permissions and I rebooted the phone thinking I had some problems, a brick or a bootloop. Instead, I tested to back up and it works well, without any error. Why this?
[G4 Original Android Development] wartomato:
Perhaps only the permissions were wrong. :)
[G4 Original Android Development] casabato:
Maybe, but what has changed the permissions? I'm confused...
[G4 Original Android Development] wartomato:
You installed something, like you said... ;) Usually the system updates permissions on reboot, but not for all apps...
[G4 Original Android Development] nitrous²:
I've dealt with this issue for a couple days until I realized it would only happen when trying to make a backup of a ROM you've restored through TWRP before.

TWRP 3.0.0.0 Date and Time incorrect!:(
[G4 Original Android Development] wartomato:
Correct, like in the older versions... So?
[G4 Original Android Development] cajunflavoredbob:
H811 with TWRP 3.0.0 here. I took a full backup and had to restore it. Upon booting up, I found that my PIN was no longer being accepted. The only option I have changed in the TWRP backup settings is to compress the backup and save to external SD (exFAT). I had to factory reset to get back in, which kind of defeats the purpose of taking a backup.
[G4 Original Android Development] Jaysus88:
Hi!

I have the same error as you guys above. nandroid doesnt work because it errors at system image backup.

fresh installation of genisys and the phone is 4 days old - was just on stock MM and flashed genisys on the first day.

Do you know how can i fix this error?
[G4 Original Android Development] wartomato:
Some reported that formatting the system partition with 3.0.0-0 solved this...
[G4 Original Android Development] Jaysus88:
sorry - what do you mean?

formatting system partition (then reflash of course) in twrp and the error is gone?

which data i will loose with this method?

i actually just finished configuring the device and when everything must be done again.. well that would suck big time.
[G4 Original Android Development] wartomato:
Okay,

1) make a backup and leave the system.IMG alone. That is what i do.

2) Some users reported that reformatting the system partition again with 3.0 would help... Yes, you will loose it all.

I prefer 1). ;)
[G4 Original Android Development] ufocus:
Same problem here. Tried flash from fastboot then rebbot to recovery. No go. Manual flash of recovery .IMG from twrp it self ,again problem persists.
[G4 Original Android Development] Jaysus88:
so i figured it out and think it would help:

my problem was that my external SD was formatted with fat32. because of this TWRP would error out at system image because this file is bigger than 4GB.

backup SD -> format with exFat -> restore Data to SD - > Backup with TWRP now working without a problem -> profit

i hope this helps a few guys.

Btw:

Is this normal for LG ROMS that the rom itself is almost 10GB big? I had only CM in the last years and was a bit shocked about this..
[G4 Original Android Development] wartomato:
If you include the sytem image and all other partitions...yes, 8-10gb.

I cannot for the love of God enter this TWRP using the hardware keys - and it's annoying ... any suggestions ... I've tried both Power + volume down, also power + volume up ... it just boots up android and that's pretty much it ...

??

p.s. I am unlocked, rooted and when I boot into recovery from quick boot i get to TWRP - but I want to be able to access it via the hardware keys ... cheers.

Running the latest TWRP v3.0.2.0

FIXED: Didn't know that Vol Down + Power -> Logo-> release power only-> press power also again and then double yes (on all erase prompts) actually takes us to recovery mode - really not logical to me ... but if it works it works ;)
[G4 Original Android Development] f2bacon:
So I used the 3.0.2.0 from the twrp to flash a stock based custom rom on my lg g4. Things went great for a day. So great that I decided to make a backup cause this is a fantastic stable rom. I hit backup and it started the usual backing up, but then it froze up for a second, the screen went black and the phone restarted. I thought that was really weird but I figured I'd just try again later. The phone was working for about 5 minutes, I put it in my pocket and when I came back to it, it was off, black screen. I tried all thinkable button combinations, plugging it in to a computer and wall charger, changing batteries, nothing. Nothing lights up, nothing vibrates. I'm currently panicking. Does anyone have any ideas? Any help is greatly appreciated!!
[G4 Original Android Development] Follow_and_Feel:
Did you hit the power button? The phone will only react to the power button, if TWRP goes into lockscreen, but you surely did, huh? :eek:
[G4 Original Android Development] f2bacon:
the phone reacts to no buttons, no combination of buttons. i cant get into any kind of mode. i cant get any vibrations, or lights, no qhusbulk. sorta screwed on this one
[G4 Original Android Development] gonsa:
So has anyone here successfully made a backup and a restore with 3.0.2.0?
[G4 Original Android Development] Follow_and_Feel:
Yes. Pretty often. Why shouldn't we?
[G4 Original Android Development] bluflight:
If i understood right, until now more stable version is 2.8.7.0 on mm?
[G4 Original Android Development] Follow_and_Feel:
Well I haven't had any problems with 3.0.0.0/3.0.1.0 or 3.0.2.0.

Everything works as smooth as butter :)
[G4 Original Android Development] rswheaton:
Sorry for the repeat question... is there any way to unlock the H815t yet?
[G4 Original Android Development] goran_oh:
Nope
[G4 Original Android Development] bluflight:
But now to make backup/nandroid, we must to select also "System Image" ? Because when i restore nandroid, not have statusbar, so SystemUI is not restored i suppose
[G4 Original Android Development] Follow_and_Feel:
Well I've never backed up "System Image". I only back up "Data", "System", "Boot" and "Cache" and when I restore it everything is in its place.

But honestly I don't know what "System Image" is, but I've read you don't need to backup it unless you wanna switch e.g. from Cyanogenmod to Stock LG or to stock HTC etc. But I'm sure a quick google search might help.

Cheers :)

Hi [MENTION=912474]Dees_Troy[/MENTION]:

first of all many thanks ! All your work is so highly appreciated!

Would it be possible for you to build a TWRP version which supports hardware encrypted devices?

See my hint here: https://github.com/TeamWin/Team-Win-Recovery-Project/issues/477#issuecomment-222518195

As far as I understood it (only?) has to be compiled with CONFIG_HW_DISK_ENCRYPTION enabled .

The problem is that at the moment we cannot decrypt from within twrp with the LG g4..

Thanks in advance

Hello.

So I have a problem with installing TWRP on my G4 H815. I unlocked the booatloader through the official LG website, it went well. It even says my bootloader has been unlocked on the boot screen.

The problem is that no matter what TWRP I use, I get into stock recovery (red exclamation mark) with 'adb reboot recovery'. I also tried the hard reset method, but it ended up doing what it is originally for, reseted my phone. Any ideas?

EDIT: I solved it by booting into the image itself with 'fastboot boot *.img' then flashed it through TWRP.
[G4 Original Android Development] seeee7:
Thanks -- I had the same problem. :D
[G4 Original Android Development] wartomato:
Ever thought that this was the "normal" way to do it on h815.

When I installed mine, all Guides on the net told me to do it this way (booting in twrp with fastboot & flashing the TWRP then from there...)

HiI tried two days in a row to do this...but to no avail, it keeps reverting to stock, unlocked the BM via LG and still nothing...Could anybody please provide a step by step to install TWRP? O tried with 3/0 ver, my phone is v20d OTA
[G4 Original Android Development] wartomato:
Like I said... I did it like Looper_98 wrote in his edit.

Connect with your pc, enable usb Debugging and mtp Mode in stock Rom. Copy twrp to the phone. Keep a copy on pc.

Get it in fastboot mode. Do not flash twrp now.

Boot into the twrp.img via fastboot boot twrp.img (Name from the file on pc)

It should boot into twrp on the phone. In this twrp screen, select install, choose the twrp on the phone and flash it.

Now reboot. Let it Finish.

Get the phone again into fastboot Mode via pc.

Verify the install via fastboot boot recovery.

You should end up in twrp on the phone...

This should roughly be the way I did it. Sorry, but cannot write it down better from my phone. :)
[G4 Original Android Development] mrqro:
Did the above...luckily back-ed up my boot, after writing the twrp...it did not boot into system at all, only in twrp...gsus I think I'm too old for this stuff anymore :(. Thanks again

I'm getting error: unable to mount storage with my sdcard. Any idea?
[G4 Original Android Development] Danmike:
Done all that except once i press enter after reboot bootloader it wouldnt even turn on.. once the device had powered down i had to remove battery put device on charge wait for the screen to say no battery soon as it done that put battery in while holding power and it would boot to the lg screen and bootloop, can't test it anymore though as i claimed on my insurance and theyve given me a G5 as a replacement device.

Thanks anyway it was appreciated to get a response as im still a fairly new poster but been lurking for years :D

Can I update the internal date of a LG G4 H815 to today's date for the TWRP take it correctly and not the date 02/22/2015 ??? it is very uncomfortable having to correct the date each time a backup is done.:confused:

Recently while using TWRP 3.0.2-0 for my h811 I attempted to move a file from internal storage to external storage.

The file was 16mb.

Upon moving the file, I was given an error message. I thought nothing of it. The message said failed.

So I rebooted TWRP.

My SD card was wiped completely, I lost 56gb of data including my backups. And I had just wiped my system partition to perform a fresh ROM installation..

I don't have a log for this because I rebooted TWRP and lost the log. Luckily I could interface with a PC while still in recovery to transfer a ROM and GApps.. But this was a crazy scenario. I've never seen thos happen before in all my life!

[G4 Original Android Development] Mr.FREE_Bird:
Do you get the following message on the webpage when you try to unlock your phone: Device ID is unmatched. Please check your Device ID. Your account will be locked if you enter the wrong Device ID more than * times.

If you get that message on the LG unlock page, then there's something wrong with their database.

Just describe your problem in an email with pictures of your device info (the sticker on de box and the info sticker behind the battery) and send it to the LG Dev Team.

They will correct their database for you so you will be able to get your unlock bin.
