Roms for AT&T V495?

Are there any working ROMs or even recovery for the G Pad F 8 (V495)?
Sent from my Nexus 6 using XDA Free mobile app

Not at this moment. We need more people to be interested in such.
Fortunately, there's a recovery for the V496 (T-Mobile variant).
We need testing for the v495.
Look here.. Make sure to back up your exisiting recovery. Then flash this. If it works, make sure to reply here or at the other thread. If not, still let us know.
In the event we ever get roms, you wont be able to flash anything for a specific device that isn't v496. Atleast until someone rebuilds the recovery for your device.
In any event. I would like you to contact me so that I can walk you through a dump of all of your devices partitions, except the personal ones.

i guess it is a start, as there has been no info on these tablets. i have one and really like it, but it would be nice to get rid of all the att bloatware. i have it unlocked and am using defense mobile for carrier but i cannot use it to tether or hotspot. looking forward to more info.

I have this device for US Cellular. I would really love to install CM rom on it. From my understanding the two problems are the locked bootloader that prevent us from installing a rom, and also there being no ROMs that support our version.

Specifically, a locked bootloader also makes it either impossible or extremely difficult to have root, too, which of course is a prerequisite for installing anything custom.

Also to mention that you can root it with Kingroot but there is a good chance it will also brick it. I have v495 sitting here waiting for a proper KDZ.
I keep searching everyday hoping I see a KDZ pop up. Nothing as of yet. I just bought an nVidia K1 Shield to use in place of this thing for now. Maybe one day I will get it back working.

King root 4.6.2 will give you root on marshmallow but only till you reboot.. Would be happy to help out in the cause.

Can you walk me through what would be needed to get that root up? I tried it yesterday and it kept failing. I am trying to recovery data lost when a user profile was deleted. Many of those recovery apps need it and I would be eternally grateful

my device is alos bricked

waiting for the proper firmware for making my tablet working. If you got one, an you help me in that please

LG V495
Hello!
After unsuccessful firmware, I had the same problem as badvs3vil https://forum.xda-developers.com/showpost.php?p=67942420&postcount=29 blurred / damaged video screen.
I was flashing firmware from LG V490 using LGFlashTool2014.
As a result, immediately after the end of the firmware, stripes appeared on the tablet screen, and nothing was visible :crying:
There are sounds of charging, the tablet responds to touch.
Please help restore the tablet!

You can install LG-AK495 to fix it.

How can i do this? Do you have detailed instructions?

It turned out to solve the problem with a distorted image on the screen. Here I downloaded the firmware:
LG G Pad F 8.0 UK495 Stock ROM Firmware (Flash File)
Download the official LG G Pad F 8.0 UK495 Stock ROM Firmware (Flash File) for your device. We also provide Stock ROM for other LG devices.
lgstockrom.com
LG_G_Pad_F_8.0_UK495_LGUK495_UK49520c_00_0718
After installation, the image is normal!!

So, I guess there's no custom roms for this thing, huh? That's a shame. The thing is super slow and running Android 6 with AT&T bloatware

Looks like it. I found this tablet sitting in my drawer and thought I'd flash some AOSP or similar custom ROM, but not happening.

Where Are The People that Flashed the H815T with the H815 firmware and Bootunlocked??

There were some people who flashed their H815T with the H815 stock rom and then used the LG tool to unlock the bootloader. Where are you guys and what happened to your phones? Did you manage to install the H815 Marshmallow on your phones?
Were there any side effects, aside from losing the Hong-Kong specific frequencies?

Anyone?

Hey mate.
So yes i did flash stock firmware for H815-eu onto my H815T during the process of rooting right at the beginning ...tbh i may have done this by mistake as there wasnt anything for H815T available in the thread. After i finished this process my phone for all the information i could see said it was a H815 but i couldnt unlock the bootloader. After this i flashed 7s rom even though it had no support and everything is fine. I am still running it and have no need to change.
I dont think there was any real trick here as deep down i dont think it converted it to a H815. Happy to help where i can but am certainly no expert. I just followed instructions at the time and tried flashing when it said no support

The only way to unlock the bootloader is to go to the LG developer site, and download an unlock.bin specific to your IMEI.
If your phone is an H815T, LG won't give you one. It doesn't matter if you're using firmware for the H815.

Thanks for writing. So to confirm, you tried the LG bootloader unlocker after you flashed the H815-eu, and it didn't work?

This is not possible at all. it's done by IMEI, so it doesn't matter which image you flash.

Yeah didnt work at all i cant remember how far i got but it was never really gonna work.
It is a pain not having unlock....but i am extremely impressed with 7s rom. Had loads of phone and this is bloody good for me.
Hope it changes with unlock...but im enjoying my G4 everyday still

Thanks for giving us details! Have you guys discovered any tips or tricks with the H815T? I installed the same rom as you as well as the lag fix you recommended in your previous posts.
I wonder when we are going to get Marshmallow? I feel that we were misled by LG when they said the H815 would be getting updates first. Most people probably thought that the H815T was the same thing, especially since there are H811, H812 etc...

Hey, guys, is it possible to flash any H815 custom roms to any H815 variants that do not have any unlocks for its bootloader? If so, is it through rooting, then using flashing apps like flashify? further, what about the dalvik cache, how do you wipe it without custom recovery?

qyrus said:
If you don't want to bother waiting you can flash the H815 MM kdz through LGUP. I've been on it for weeks with my H815T and everything works as it should. When the official H815T update is released it'll be pretty easy to swap over as well.

The above genius found a way to put Marshmallow on an H815T with no problems! It sounds like he did this: http://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803
But I can't figure out what kdz he used and whether we can upgrade without losing our apps/data/ instead of doing a full wipe... Thoughts anyone??

His directions weren't clear about whether he upgraded or wiped before flashing. So I followed the directions for upgrading....
And it worked! My H815T seems to be working fine on Marshmallow and all my apps and data are still there!

H815 TWN, differences from EU?

I am certain my G4 is TWN, from the box and the software version. But what are the actual differences to the European H815? Specifically, can I flash European KDZs or use the EU command for flashing a rooted /system image?
Code:
dd if=/data/media/0/system.rooted.H81510c-EU.img bs=8192 seek=55296 count=529920 of=/dev/block/mmcblk0
Thanks

I have a the TWN version too damn it. - that's what happens when you buy from a global vendor over the internet .
Good news is that you can flash the EU rooted system image. I did and it worked fine.
Bad news is that you can't unlock the boot loader (yet), which means no TWRP or custom roms and flashing a stock Marshmallow leaves you without root and no way to downgrade.
Cheers
BTW I don't know of any differences between the EU and TWN devices other than the version coding - to me it just seems to be a way for LG to control their different markets.

Thank you for this. I do not want to unlock it just yet, since I bought it from a local vendor and I have a 2 year warranty with them. I see there is already a rooted image for v10d TWN, so I will flash that soon (are you sure the parameters for the dd command are the same?).
Sidenote, it would be nice if we could compile our own KDZs and make rooted ones.

I can't really comment on the all the parameters in that command string except to say that it's one I used and it worked well. Whether those numbers would need to be modified for the 10D image or not I can't say - I would suggest you ask the author of that original rooting thread.
BTW you can't unlock the bootloader on the TWN version just now in any case. I tried the official method over the weekend and was told the TWN version was not supported. There's unofficial unlock method available for any G4 variant yet either but people are working on it.

Probably the parameters aren't different between firmware images, because they depend on the partition table of the device.
Now waiting for a version of Xposed that is confirmed not to drain battery. Thanks again!

I'm running xposed now with about 10 modules. I don't see any great battery drain.

I did the same thing, buying online and getting stuck with TWN. I came from a GS6 and was thinking "I'll wack an AOSP ROM on the G4 and I'll have the perfect phone". Now I'll probably never buy another LG even though I actually like the G4 but when we pay close to $1k for a phone we should be able to do what we like with it!

There is a thread for stock marshmallow which you can install with flash fire but there's no root available with that option just now.

Sorry. Missed this while I was away.
The thread I'm talking about is http://forum.xda-developers.com/g4/development/stock-h815-20a-stock-rom-t3233049
BUT be warned you will lose root !!. So far as I know just now there is no way to get root on stock MM without an unlocked bootloader. This may have changed inthe last couple of days - you'll need to read around the forum.
ALSO there is no sure way back to L is you decide you can't live without root (I certainly couldn't so I'm waiting for further developments). I think I read that someone here more-or-less accidentally managed to recover back to L but I didn't really have time to take in all the details so futher reading needed if you want to take the risk.

Lg k10 at&t

Hey all. I Have a AT&T LG K10 (K425 Build number is MXB48T). As the new model is slated to release, im becoming more set on the opinion that our devices will not be receiving Nougat. So my sights have been set on rooting. My question is this: what can I do to root my device? (And to give you a clue to my experience, I have been using a Huawei fusion 2 from 2010 ( old I know. I didn't have a choice in that one ) which had a slim ROM on it, with a hugely modified system which was for a virtual memory file to increase its performance).
I've noticed that there isn't exactly much development on other versions, but if someone could point me in the right direction, that'd be great.

Non of the k10s that's running marshmallow (so 95% of them) can be rooted by any one click stuff (like kingroot,...). So the other solution would be to install Supersu in TWRP. In order to get into TWRP you either need to be rooted (obviously you are not) or you should get into fastboot and boot into TWRP from there. The MTK versions can get to fastboot and boot into TWRP without any problems. However the qualcomm versions are rarely able to get into fastboot and even if you manage to get into fastboot there is no way to flash or even just boot into TWRP... not to mention that you need to unlock your bootloader first which is also problematic in the qualcomm case.

My former LG LEON had the same symptoms. I guess it's qualcomms "secret" weapon against people trying to validate their warranty even if they messed up the device themselves...

Is it possible to downgrade to LL, and then root?OR Would doing that just be superlative to have MM?

You can root if you are in MM too... Forget KingRoot... I am working on a new root method based of dirty cow. It involves very deep analysis of "init" and replacing sepolicy and getting root. It will be out in few days.

i will test it tonight but the Q here can i relock the bootloader or what ???
oh and thanks man for your hard work i thought that i will wait for ever for the unlock.

Can someone give an example how to find Out what to Type for "<your aboot partition>" ?

pvineeth97 said:
Hi guys!
Disclaimer:
No more secure boot error!
I thank my friend @cerg2010cerg2010 for helping me out in patching the aboot.
-> Requirements:
LG G4 LGH818P
Rooted Phone
-> Steps:
(1) Downgrade to Lollipop version of the Android. Download here.
(2) Root your device.
(3) Download the patched aboot file. Click Here.
(4) Connect your phone to the computer. In command prompt, type "adb shell".
(5) Transfer the aboot file into /sdcard/ folder.
(6) Type "su" to enter the root shell. Then type "dd if=/sdcard/aboot_237568.bin of=/dev/block/<your aboot partition>".
(7) Restart your phone by typing "reboot".
You have unlocked your bootloader!
Refer Notes for more information.
-> Notes:
1) The aboot_237568.bin is the patched version of aboot partition of your device. Secure boot validation has been patched such that secure boot is always valid, so you can flash your own TWRP and Custom ROM.
2) Don't upgrade to any updated version of Android if you get any through OTA update. It might brick your device.

Sounds amazing. Please provide the details about the patch meaning what have you done exactly to get that patched aboot?
Could you please download my latest TWRP beta(!) and provide me the recovery log? Or someone else of course
My latest beta is a unified variant and so should work for h818 as well but maybe I need some small adjustments..

When you flash the patched aboot, the bootloader is unlocked. You don't need to do anything else.

Patched the secure boot validation function. The patched aboot has the secure boot set to always valid condition no matter what image you flash.

And after flashing KDZ the bootloader will still be unlocked ?

Proably not. Aboot is part of kdz flashing.

This is fantastic news! H812 user from Canada here hoping you can make this patch process work for our aboot too!

As in case of g flex 2..
Everyone be warned..
The aboot on lg k10 is not signed
But in lg g4 there is a hash verification to aboot.
It may result in a hard brick.. so be warned

first of all , thats great news. this is the same method we use in h815 with the unlock.bin from lg but instead of pushing the file directly, we flash it in bootloader. clever and nicely done.
since its public you should share it the right way not like this. i mean this is not a development project, this is about unlocking and flashing twrp. it should be a DEVDB thread in general under utilities section so that everyone can find it. Also the title should be: "Unlock Bootloader H818".
As it is, in a week or two its gonna fall at a second page and in search results also almost noone is gonna find it cause of the title.
in the op tell them about mmcblk0pX. They are not all expert , they don't know mmcblk0pX in g4 is like our sdX in linux.
Tell them the ls command to find which mmcblk0pX is the right one or how to find it with a root explorer. As it is, its just gonna give them an error and gonna ask you everyday about that.
We need h818 users too. To be able to start developing for more variants its important. Cooperate with steadfasterX to correct bugs in twrp (if there are any).
This would be the 1st step to start flashing together with us , custom roms.
Finally , Welcome H818 users
