[Q] bootloader related.

Holla! i'm thinking about getting the Zenfone 4GB ram variant .
but there is one thing that concern me and this is Custom ROMS
is the bootloader unlockable?
will it be possible to get CyanogenMod up and running on the device?

Not yet.

My 551ML does not show a locked bootloader, so I am able to flash a pre-rooted system.img file via fastboot. My guess is that CM and AOSP compiling will occur soonly.

To test whether the bootloader is locked or not, it would be a better idea to flash a custom kernel built from sources and see if it boots. According to the Asus forum (read here) the bootloader is locked and for now there is no plan to provide a way to unlock it.

I never understand WHY vendors like Asus, Motorola or Meizu makes ultra powerfull phones ... what we BUY for MONEY, and lock them for never let you install what you want...
I really want this phone ... but never will buy it if I can't install an AOSP custom made ROM ... (no CM, i hate it)
that why I always buyed unlocked phones like Nexus phones or my actual OnePlus One...
i hope the Lenovo K80, who will be released 30 april will be unlocked !
or the Elephone p7000 (for this, you can already find CM, AOSP, Flyme etc... roms on the OFFICIAL website !!!! )

I agree. I want to buy this phone, but I'm not going to until Asus allows to unlock the bootloader.

and NOW i'm REALLY interrested oO
on FlipKart you can now reserve a 128Gb version !!
NEED IT, but just if the bootloader and custom roms come ....
if not, I will buy the Oppo R7 or Elephone P7000...
seriously, what it cost to Asus to unlock the bootloader ? and let owners use our phone that they buyed ....

but..
In the warrenty document over on Asus Zenfone section the following details are interesting
Unusability or damage to the Product caused by installing and using the Unlock Device App, which is a utility that will unlock your Product's boot loader but will render the warranty null and void.
The pdf file can be reviewed from the Asus website
Does this help?

Odds are they were lazy and copied the warranty document over from the one for the previous Zenfone devices, which had bootloader unlock methods released by Asus. Hope they do the same with the Zenfone 2.

hmm...
But has anyone tried to unlock it by this method!

If bootloader is unlocked by default, people who are not suitable for that will brick the phone in a higher chance, with more issue varieties which increase the cost of after sale services like maintenance. Unless there is no warranty or support for the phone after sale, vendor will not unlock the bootloader.

I am under the impression the ZE550ML zenfone 2, I have, i that the boot loader is locked.
As it is proving impossible to root it using the pre root images available.
I have 2 sets of instructions that I have followed to the exact method, yet the phone will not root !!
1) ADB sideload method, in recovery mode, choose the ADB option. Zip file is in the folder with the ADB + fastboot files.......................................message in command is "unreadable zip or not recognised'......
Checked ADB device and ADB recognises zenfone attached to computer!
2) turn phone on and have debugging set.......................(no recovery mode) place system.img into fastboot folder...........open command via the shift + right click option............submit the line 'fastboot flash system system.img.........................continuously waiting for device......nothing else
Ive never known a more difficult phone to root, especially with all the easy straight forward instructions out there to follow.
So I'm of the impression the bootloader or something is stopping root
Anyone else had the same issue?

What is the best way to root G4, whilst keeping it "friendly" for warranty claims?!?

What is the best way to root G4, whilst keeping it "friendly" for warranty claims?!?
Hi, forgive me if this thread isn't in the appropriate section.
I have a bit of rooting experience, haven't done much in a few years though, (knowing that there are now several ways to root devices), and have just picked up the G4.
Now I'd like to root the G4, but keep the stock rom, (6.0) and mainly will be just running xposed to edit and muck around with LG's ugly skin. I'd still like to be able to receive OTA updates, (even if the OTA update may remove my root,) as well as hopefully still be fine if I needed to return the device under warren.
I've been reading around and apparently you must unlock the bootloader in order to root for Marshmallow? If i were to still do this, could I keep the stock recovery at least, or if not, would I be able to easily revert to stock with a stock recovery and relock the bootloader?
Apologies for my ignorance, just trying to figure out if I should really be rooting or just chuck on Nova launcher and be happy with LG's offerings. Cheers

Keep it on a stock rom and if yoi have a carrier varient then try to not change the boot logo lol idk just a guess.

Yes to reflashing stock rom
Yes to relocking the bootloader
So you are clear to make whatever modifications you want, you can always revert safely.

Once your bootloader is unlocked, you cannot relock it. Your device will always show a message saying "Bootloader unlocked" after turned on. Warranty is likely to be declined then. BTW: You have to get your unlock.bin file from lg, agreeing to void your warranty. So, even if you smash your screen and they cannot see the message, lg knows it is out of warranty.

Since when do you have to get the unlock.bin? We unlock from fastboot. Have you confirmed by trying to relock from fastboot? I read otherwise from another thread.
Furthermore, a quick search around indicates people who have unlocked and rooted have had their warranty honored despite software changes.

Unlock from fastboot is only possible after flashing said unlock.bin file, which can only be obtained by lg and is unique for each device. Furthermore, I had an unlocked, bootlooping h815 and lg refused warranty to me (in Germany). Got my phone replaced by my vendor on eu law which only applies if the defect strikes in the first six months.
So, while some people are lucky to have their phone repaired despite an unlocked bootloader, I'm really happy for them, but lg is not bound to repair it on warranty

Ah I see. You have a h815. I have a h811. Our process differs there.

Hmmm, thanks for the info guys. Its not from a carrier, i bought it outright. Seems like i might just have to keep it stock, its not too bad as is, guess ill just have to live with it. Thanks for the help though.

At least you can root with locked bootloader

Not under marshmallow

You can do none of things you listed keeping it stock. First of all google change policy and in marshmallow you need to flash modified boot.img in order to flash custom recovery and/or to root it. As you know the bootloader has to be unlocked but there is no way to relock it. So sorry, but impossible.

People need to understand a simple thing.
You either mod your device and lose warranty or you keep it stock.
It's that simple. People worried about warranties and ota updates are on the wrong site.

Buying HTC 10 from T-Mobile - what's the difference?

Hello
I am thinking about buying an HTC 10 straight from T-Mobile. My question is - will root/ROMs/recoveries work on the T-Mobile variant as well? Are they completely identical?
Thanks in advance :victory:

To answer your question most root/roms/recoveries should work on the T-Mobile variant. It isn't identical because the tmobile variant has tmobile added software and its made to fun on their network. i have used every single HTC One starting from the M7. this year was the first time i haven't. I instead went and got the unlocked model and I'm using it on T-mobile of course. My main reason of always rooting and s-offing my device was to be able to convert it to a developer or unlocked edition. This time with the unlocked 10 i haven't gotten the need to do any of that. I haven't unlocked the bootloader yet although I have the option in the settings ticked that I could in case i would need to.

What's the difference between S-Off and a Bootloader Unlock? Is it like Samsung Knox - where they only find out you've modified the device once you send it in - or does HTC get notified as soon as you S-off/unlock it? Thanks for the answer.

Bootloader unlock is what allows you to root, flash roms and etc. This is needed for any type of modifications. S-Off is not needed for this. What this does is allow you to further modify your device. For example, it let's you flash different firmware or different roms that normally your phone wouldn't work. So in my case the last few years I would take my T-Mobile M8 and M9 and use s-off and then flash them with official developer stock software and converted them into developer edition. the app to S-OFF is $25 but it's the best money you will spend
There should be a thread that explains this further if you need any help.

Anyone tried Rooting the H815 with Windroid 3.1 ?

Just came over this at the Nexus 7(2013) xda thread, and noticed that it also now supported the LG G4 H815 ...... was wondering if anyone has tried it, and if it worked fine on Marsmallow firmwares.... it says it can unlock the bootloader, flash recovery and gain root !
if so is this must be the first "one click" root tool for the G4 that not claims money to do it for you

Will this work with LG g4 H815 Taiwan on marshmallow? Been looking at ways to unlock its bootloader twice a week for 4 months :|

Thats what I wonder too..... it says all H815 variants so maybe? If this works well on the G4 this would be a real easy way to require both Twrp and then gain root in a easy way :fingers-crossed: , thats why I wondered if anyone had tried it out

I tried and it asks for unlock files .bin

Hey guys, I tried unlocking it but it didn't work and after a bit of research i have gotten the impression that there won't be a way to unlock its bootloader for a long while (maybe never). I've had enough of LG and their BS so im selling my phone and buying a oneplus 3. I would recommed you do the same before the prices drop too much.

is the LG G710pm impossible to root?

Is this phone impossible to root or is there just a lack of interest in figuring out a way to unlock the bootloader? I love this phone but really miss the freedom I had on previous devices to install certain apps and run different roms. I've never had a device that has been out this long without a root available.
I guess what I'm asking is if I should consider going to a different device if there isn't a way to unlock the bootloader in sight or stick it out because it'll happen in the near future.

So far, no way to root it yet, I am stuck on the Sprint G7 myself and currently fighting with Sprint to allow me to swap to another device. I know it wont work but at least I am voicing my dissatisfaction of this device with the lack of timely updates (still on November security). If I had known now when I went to Sprint back then, I would have never chosen the LG G7. The phone itself is decent, hardware is good but lack of root, lack of bootloader unlock, and lack of timely updates make the device unusable in my opinion.
I personally am hoping I or someone else can find an exploit for ROOT and eventually bootloader but so far, not much traction has been made in that department.

I have a g710pm, running Android 8.0.0
I see in developer options there is a selection that says, "Enable OEM Unlock" wouldn't that unlock the bootloader?

Nope it will not limited fast boot won't let you run the command its basically useless

You can take a look at my post, there are all the models in my country to unlock BL and ROOT, but only in the hands of a few people, they do not intend to share this, and through this to get benefits, they provide remote unlocking and ROOT services , but need to pay, which is expensive for me, I don't know English, sorry, the reply is translated by Google...

Hey everyone! As I had said earlier, the rumors are true, most G7 variants can be bootloader unlocked. I searched many Chinese websites that had already shown rooted G7 phones but showed no clear methods besides "remote unlock services". Now the method is known! The engineering bootloader from a very unique AT&T V35 V35AWM model (abl_a and abl_b) is flashed via an Octoplus box on the G7 when in QDLoader 9008 mode. This guy from Ukraine motogvasyag posted his methods on 4pda.ru and are now on XDA here: https://forum.xda-developers.com/lg-g7-thinq/how-to/to-unlock-bootloader-root-models-t3928505
Please check out the thread, and do donate if you can. He is doing these Octoplus flashes for free.
**This method won't work on T-Mobile model (G710TM and others). I'll still be on the lookout for any T-Mobile methods.**
