[Q] Versions and which can I use?

This is my very first time actually owning a device with that many Versions, in the past I've only rooted Nexus devices which is easy and straight forward.
I currently own a LG-H815; Main Software Version: V10e-OPT2-HQ; Software Version: V10d-EUR-XX
So do I have a h815 10e or 10d?
Do I have to go from a h815 10e/d to the EXACT same pre rooted image or can I use pretty much every h815 10abcdef Image?
I am sorry if this has been asked before, but the search function seems to not work atm.
Thanks in advance

Zenfone 2 (ZE551ML) No further updates? regional thing?!

Good evening.
I'm living in Japan and after years of head aches and troubles with japanese-market-only phones I decided to get a new-no-contract-sim-free phone
I chose the Zenfone 2 due to its price and update availability..
It says it should get an update to Android 6.0 but when I tried to update I noticed its only on Android 5.0
No 5.1 or 5.2...
This phone was release in January if Im not mistaken.. is it possible they didnt update it nor fix any bugs in a year ?!
OR...
Does it the next chapter of me getting screwed cause I'm living in Japan?
I've check about the update and it says on their site FAQ that it is possible to update manually... Push a zip file..
https://www.asus.com/Phone/ZenFone_2_ZE551ML/HelpDesk_Download/
The latest version is:
Version WW_2.20.40.139
but I noticed there are WW CN TW and *drums rolling* JP versions...
Now, in some of the other versions I saw mentioning of JP thingy being updated... does it means I can Install a WW version on a JP phone ?
example:
25.Fix JP FlipFont issue
29.Remove BookLive from JP SKU
They write that:
3. Only apply to same SKU update, Example: WW->WW, CN->CN, .
so.. do I have to wait for a JP SKU ?!
My current ver. is:
Android 5.0 JP_2.20.40.97_20150917 (update from 3 months ago? yet still android 5.0!?)
Baseband : 1527_5.0.35.1_0815,1527_7.0.20.0_0723
Kernel version: 3.10.20-x86_64........
Build number: LRX21V.JP-ASUS_Z00A-2.20.40.97_20150917
Again.. is this a regional thingy?
Are all other Zenfone 2 still stuck on Android 5.0?
Btw I've got an unrooted 2GB version...
Thanks in advance to all the helpers

6.0 hasn't come out yet. We are all waiting for it.

Hi the whole "latest" android version thing is a plague caused OEMs and/or the dreadful carriers versions, they always (think they have to) add their flavor on top vanilla (stock) android, be it a launcher (the interface), replacing stock android and/or google apps, sometimes with good and fast results (e.g. Motorola) because they add to stock android rather than changing the whole thing (e.g. freaking Samsung).
You're better off flashing a custom ROM, if you follow instructions CAREFULLY it would take an hour if you're a beginner as it's hard -but not impossible- to brick newer phones.

Question though..
Since its the JP SKU .. will I have problems ?
I had lots of problems on my XPERIAs, since they had JP systems/kernel/everything...
I only have experience tinkering with various japanese xperias... this is my first ZEN so... It should be easier to root and such than sony's... right?

It's easier to root and unlock bootloader than sony! As for changing JP to WW version of the firmware there is a guide how to. No risk of brick since you are familiar with these procedures as i read.

Hi @major9686
Do you recieve the monthly security and bug fix updates?
It seems that the japanese market has both WW and JP SKU phones. Hence the anomaly on the support page.
I don't know, flashing WW might break your cellphone service.
So 2.20.40.97 JP is the version your phone should have.
Yes the stock is still on android 5.0. and in time you will get 6.0 as will we all.

Android 6.0 is confirmed. But will take some time. This is true about most of the phones, except few who gets quick updates. Asus is still better than others.

I dont really like my Asus so far ...
My EeePC gave me problems back in the day, the battery died and I cant replace it no one sells it anymore...
It barely lasted 2 years... now it only runs when plugged and even then lags (even after getting an SSD inside)
My Nexus 7 is also a bit laggy even after factory reset, only bought it 6 months ago
and my recently bought Zenfone 2, already been to repair once but problem still persists. Ear Receiver doesnt work, only if I press the screen around the ASUS logo, some sound gets out.
GPS is messed up, gyroscope as well.
SIM Card 1 is giving me trouble, only after several resets, factory reset and whats not it suddenly became readable without becoming unavailable after every few seconds...
and the most annoying thing, after the repair the USB port became loost, the cable isnt held in place as well as it was before the repair.
But you get what you paid for... so far I had a few Xperias and they all had great build quality. I'm soooo sorry I decided to get an asus this time
whats more, even getting an Asus sim-free I get stuck with the Japanese kernel which doesn't allow me to remove the friggin shutter sound from the camera unless I'll root it
Getting this piece was a big mistake. build quality is sooo bad!
Last Asus I'll ever buy...
In PC components already learned my mistake years ago and changed to Gigabyte...
And dont get me started on being stuck on Android 5.0 ... at least with sony we get 1-2 updates...

I got tired of waiting for an update. Bad battery life and Asus apps using most of the memory so I decided to unlock the boot loader yesterday with their software, rooted and installed Bliss Rom based on CM 6.0.1 witch is awesome

Hi,
I found the latest 2.20.40.164 firmware for Japan SKU on their support website.
NB: This is a full ROM.

Time to root my LG G4 H-815TR v20i. What do I do?

I have boringly used an LG G4 for almost two years now. Just after a few months of using it, I had the bootloop issue, LG gave me another G4 which I've been using for more than a year. But I believe it is time to unlock the true potential of my phone. I've transferred all my pics and vids and similar stuff to my computer, so now it's go time. The only thing is... I don't know what to do.
Model number: LG-H815TR
Android version: 6.0
Android security patch level: 2017-03-01
Kernel version: 3.10.84
Build number: MRA58K
Software version: V20i-TUR-xx
These are the info I think are relevant. I have no experience in rooting whatsoever. What do I do now? (an up-to-date detailed guide also works for me)

Hey,
I still need help for this.
I've checked online and couldn't find anything for H-815TR v20i running Marshmallow.
Can someone come to my rescue?

It's very easy:
You can't unlock your device because LG allows unlocking of the 815 international version and 811 only.
Marshmallow can be rooted on unlocked devices only (so not on yours).
If you really need root you need to downgrade to lollipop.
Downgrading to LL requires a compatible anti roll back version. Search the forum for the code which displays your current antirollback version and the how-to for downgrading and rooting LL
.

Oh okay.
So I can't root my phone as is, I need to downgrade to Lollipop to do that.
Well I was thinking of flashing some custom ROMs and maybe underclocking for more battery life but given that this is my only smartphone I'd better stick to its current state then.

find the service menu for your phone. Google lg g4 service menu. call that number. check anti roll back version (last entry) if 0 you should be ok to downgrade, if not 0 downgrade will likely brick your device.
https://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803
read carefully and ask a any questions before using LGUP if unsure
after that you can root with https://forum.xda-developers.com/g4/general/lg-g4-100-root-success-directives-root-t3180586
or upload your img file and kindly ask someone to root it for you and re-upload it

Anti-rollback version is 0.

I need some tips

Hi there, i just bought this phone and it is already rooted, i tried to upgrade OS (it have Android 5.1) but for my surprise i cant because of root, im really new in all this and i need help with some things like...
Can i upgrade to Android 7.0 with the rom from the official page ?
My phone was SIM unlocked via Unlock Box, it is probably to have any problem if i update my OS ?
Which is the best Rom that you tried ??
Greetings.

Downgrade A520F from Oreo to Nougat if Samsung already blocked downgrade

I have moved all of our devices to A520F and TAB A (2016) runing LineageOS 14.1 and I am very happy with it. The bad side is one of the A520F, which aleady costs me 2 days because wether heimdall nor odin (i setup a windows machine to test it under windows too) replied with an valuable error when trying to flash nougat, except failed. I finally found out the at some version (i think August) it is not possible to downgrade the bootloader. Now I have one device running with an unsupported LineageOS 15.1 and had to hand it out to our Boss, because all other device had their new owners. She is kinda unhappy, that hers is different from others , but we cannot buy more A5's just to maybe receive one with an downgradeable Oreo version and trash all others.
My question is now is there any possibility to work around this and downgrade her phone to Nougat to be able to run 14.1 on it too. Any crack, special keys or whatever.
Thank you very much for any hint.

Not at the moment, but 15.1 won't be too far away.

My experience: Downgrad is possible, but you can't downgrade all parts. Not 100% sure, but just don't downgrade BL.
