What's a general way to install recovery on a Z3?

I just upgraded to 5.1.1 and lost recovery, but I have an unlocked bootloader. I've looked for hours but can't find a guide for that version of the firmware. I'd like to install TWRP, but I'm not sure if it's kernel-dependent.
Does anyone know which version of TWRP I can install on my phone? Do I need a different version for each kernel, or can I keep using the same one? Where can I find it?

For unlocked bootloader quote:
Use the Kernel Builder to repack the kernel you are using now to replace the built in recovery with XZDualRecovery. Installing the locked bootloader variant will either not work at all or require unexpected operating instructions.

I suggest reading a lot. I have yet to unlock mine. I'm shootin for Tesla's rom myself but am waiting (forever) on a new power supply and a brand new 12.5" tablet as well.

Thank you. I tried installing the previous recovery I had and went into a bootloop, so it's definitely kernel-dependent, as you say.

Hmm, do you know how I can install that? I don't already have a recovery, and that's the only way I can figure out that this can be installed...

New in MI4C

Hello everyone.
I live in Brazil and I bought at the Aliexpress MI4C Xiaomi. I haven't received it yet, but I've already started researching ways to use it with another ROM than the original. The seller sends the device with google apps and multilanguage option. So, he makes some modification in the ROM, and says to not update the ROM officially on Xiaomi servers.
I see a lot of complaints about the Chinese bloatwares in ROM and so I wanted to install one that was good, but nothing with applications in Chinese or unnecessary ones.
My question is: in this case the bootloader is already unlocked?
In the meantime, I sent my request for unlocking bootloader to Xiaomi and received the SMS containing a link. As soon as I get the cellphone I intend to do the procedure. There is a risk of bricking the phone?
I’ll do appreciate good links with how-to and good ROM to daily use.
Thank you.

The seller shipping a modified ROM and telling you not to update the official would suggest your bootloader will not be locked. For now only flashing the latest official China dev builds will lock your bootloader.
Getting pre-approved for unlocking couldn't hurt though I guess.. just in case. You might need to have a working Xiaomi framework in your ROM to register your phone once though. If your ROM does not have the xiaomi services, I would suggest either Xiaomi.eu or sMiUI as a ROM, both are pretty much stock MIUI with some chinese bloat trimmed.
But most likely you will not need to unlock your bootloader anyway. You will need to check your bootloader through adb anyway before doing the steps to flashing a new ROM. You will best be flashing your recovery through adb, the instructions can be found through most ROM pages or simply searching TWRP Mi 4C. The command to check if it's unlocked is
Code:
fastboot oem device-info
A very extensive directory can be found in the INDEX thread, first in this forum.

you cannot check the bootloader locked or not by that way. My phone when checking this, gets the input "bootloader unlocked: false" but I can flash other recovery freely.
in his case, he is using a modified rom, it means his bootloader is not yet unlocked. Right now, if he wants to come back to chinese rom, he should use Mi flash to flash his phone. If he wants other rom like CM13, he should download the latest TWRP and the rom, put the rom into his phone storage. Then try to go to fastboot to flash the recovery, then go to the recovery and flash the rom.

Ah, that might be incorrectly reporting indeed. In any case when trying to flash recovery, if you're locked it'll simply fail and won't be harmful.
But why would you think his bootloader is not unlocked? If he's using a modified rom, it was probably flashed through fastboot or a custom recovery, both require the bootloader to be unlocked.
But even if he was not on a modified rom, stock Mi 4c have always come bootloader unlocked. Someone would have to have gone out of their way to lock the bootloader and I doubt any reseller would do that, they would risk a lot of refunds from angry customers.
I strongly advise against using miflash to flash any official rom unless you have no choice, since then there's a chance you WILL lock your bootloader. For now only dev builds are locking it, but the next stable release might very well too.
The first step should be to flash TWRP
The second step to stay away from Official China build
The third step to keep away from Official China build
The fourth st...

^ sorry my bad.... I was not focused. Actually I mean his bootloader is unlocked .
The safest way is flashing via computer, using mi flash or flash twrp image. You are right

1. Ur phone not lock bootloader
2. U can flash custom recovery...(TWRP)
3. "MUST" Stay away from official MIUI ROM
4. Flash whatever u want...sMiui, CM13, etc,etc
5. Remember Point No.3
***Btw, download official Fastboot ROM and keep it to ur drive, for just in case if u want to sell it again

Hello. Thank you all. I just received my phone. Great, btw. I'll read again and again all instructions and try. Thanks again!

Even as a last resort to getting your phone working if you did something wrong, please don't install the newer official roms, it's the mistake I did this weekend now I have a locked phone with a rom that has force-closes everywhere and absolutely no way back.

Don't flash the latest chinese rom.
No.
The only scenario where you would want to use miflash to flash a chinese rom would be as a last resort to flash the fastboot version of V7.1.6.0.LXKCNCK to restore your phone. Any later version will lock your bootloader.
If you don't care about locking your bootloader and the arduous process of unlocking it, you're easier off just taking all the latest updates OTA via the updater.

Hello everyone. Thanks for the help. In fact my bootloader was unlocked. I flashed twrp 3.0.0.3 and flashed the CM13 teamluminial, Android 6.0.1. Excellent. Thank you.

Hi!
Same scenario here..
I will receive Mi 4c with the Bootloader Unlocked, Rooted and the Multilanguage ROM.
But I have already received from Xiaomi after my request also the number for the official unlock procedure but now I'm a bit confused..
Do I have to unlock the bootloader once and for good with the official way?
Because I've read that the unofficial way isn't so secure in long term.
Do I have to install from the Updater the latest Cina Dev ROM and after that to proceed with the official unlock? Or it is better to use the Fastboot ROM?
Please could some one tell me in any case what to do ?
Thanks !

If you don't flash something that will lock your BL, no need to Unlock.

Ok first I must check the status of the bootloader to be sure that it is unlocked (via cmd control or cpu-z)
And after that can I choose an unofficial weekly miui.eu international ROM and install it?
Can I download and also update every week via Updater this ROM without issues?
At the moment my problem with flashing is that I don't have my pc (the one I have now runs win xp) and I don't want to stuck with the eventually malware or fully spammed modified rom of the reseller..
Which options do I have?

TWRP works perfectly. The backup is simply stored in your internal storage。

Update 6.0 mm full tmo & skinny debloated version

6.0 Marshmallow with insecure modded kernel and TWRP recovery​
This needs testing by someone else. It has been flashed on my own personal phone with no issues.
Requirements- Unlocked bootloader, Draken FX's Bootstack -the fixed version by Turbo2012 found in DrakenFX's thread for the flashable 6.0 update. Must be currently on an LG based ROM NOT CM. After install flash SuperSU install zip, post any issues. You will be able to ADB and Fastboot even if you can only boot splash screen with this kernel so you should be able to recover from almost anything multiple ways. When time allows I will put up a source built 6.0 along the lines of Game Theory's Katana ROM. Everybody is welcome to everything I post and I strongly encourage the young crowd to get involved, these phones don't support their selves.

Does that mean a fastboot oem unlock, or the OEM unlock in the developers tools. If you mean fastboot oem unlock, is that available once you flash stock MM, since it is not in LP?
PS - thank you very much for taking the time to pick this up. Back in the days of the Galaxy S1, I had a build environment setup, and a lot more knowledge (it is amazing that if you don't use it, you lose it), but I have a son now, so I don't have the time to invest in all the hobbies that I want anymore. I will definitely be a guinea pig for you. I am not actually aware of a way to brick the Metro or TMO versions of this phone since we have a kdz -- it is not possible to blow up firmware download mode.

I would prefer to be bootloader unlocked through fastboot oem unlock before doing any mods in 6.0. Every single time I did not I got secure boot error. If you make any system change on 6.0 with locked boot it will not boot.

Thank you for taking the time to do this.
:good::good:

So it's still not possible to update from Lollipop to rooted Marshmallow without unlocking the bootloader via fastboot? A secure boot error might as well be a brick to me. Oh well.

The main reason I made this was because I can never boot recovery or fastboot manually ( ex. w/hardware buttons) when you have the insecure kernel adb works when at the splash screen so it's easier to recover if you have any problems.

If you used Draken's guide to root and install TWRP on lollipop, your bootloader will be unlocked.

You only need a "soft" unlock (enable oem unlock in developer mode) to root / install TWRP on lolipop -- no PC required. MM however, requires a "hard" OEM unlock, and that requires a PC.

Yes, you have to unlock your bootloader with fastboot oem unlock. If you flash this without unlocking your bootloader you will get a secure boot error, and you will have to flash a KDZ and start all over.
Lolipop doesn't come with fastboot. So you have to follow Draken's thread to get stock MM on your device. There is NO other way. Once you have stock MM you can unlock your boot loader with fastboot. Once you have an unlocked boot loader -- THEN you can flash this if you want.

Waiting on the debloated version.

I can vouch for this. That's exactly what happened to me when I tried to flash this without unlocking the bootloader with fastboot. At least I finally managed to ship my device to LG for repairs today. I'll just chalk it up as another lesson learned.

You didn't need to ship it back to LG. Firmware download mode is always available (hold vol up while plugging in USB cable -- just vol up, not vol up + power). Continue holding vol up until FW DL mode displays). Then just use the LG flash tool to flash a KDZ. It is a PITA when you have to go back that far, but you can't brick these phones, not with software at least -- they would need to be physically altered

You sent your device in for a soft brick? You should set up the flash tool for our phone with a 10j.kdz before doing anything. Hope you get it back soon.

Debloated version
Fixing some force close problems on a debloated version now, should be up later today or tonight.

@runningnak3d
Flashing the KDZ seems easy enough. But how could I fix it without unrestricted access to a computer? And my stock charger is broken without a USB cable. I had no choice but to send it in for repairs. Guess I'll be stuck on Lollipop for a while longer, at least.

Can the bootloader be unlocked on the CDMA versions (ex. Boost, Sprint, Verizon)? If you can I will make a variant for it. But if you can't NO.
I just found out that the unlocked bootloader in 6.0 survives even the .kdz flashtool. So once you unlock your boot in 6.0 with fastboot oem unlock you never have to do it again even survived kdz downgrade to lollipop and update to 6.0 stayed unlocked.

Question: Rooted Concept?

Hey guys,
I tried out the Android Concept MM when it first came out and i was a huge fan and insanely satisfied due to it's stock-like android experience, however the only thing keeping me away from using it is lack of root and xposed, however i was wondering can i just make a pre-rooted ftf with the ftf of the concept with recroot 4? like i would with a normal Marshmallow ftf or am i completely wrong?
I would appreciate the help thanks!

Concept ROM uses dm-verify, so it's unrootable on locked bootloader. However I've managed to root it on unlocked bootloader before somehow. I'll try to explain as best as I can:
1. Download and flash concept FTF http://forum.xda-developers.com/z3/...arshmallow-t3229030/post66825447#post66825447 (this is latest one I could find)
2. OTA update to the latest version if you want
3. Download Systemless SuperSU zip and place it on SD card https://download.chainfire.eu/921/SuperSU/UPDATE-SuperSU-v2.65-20151226141550.zip
4. Flash recovery via fastboot (it needs unlocked bootloader) (for recovery I used this one) : http://forum.xda-developers.com/z3/development/z3-twrp-2-8-7-0-d6603-t3273996
5. Don't leave fastboot mode! Navigate with volume keys to "recovery mode" and click power button to enter it.
6. Flash SuperSu you downloaded earlier and then reboot.
7. Done, enjoy your rooted Concept.

Well, ZyxxOS has Sony's Concept based kernel. The developer itself at first thought it will work on locked bootloader, but it didn't. You could try to flash original Concept .2099 kernel, but I don't think it will work.
As for DRM, you can easily backup them before unlocking, but it's up to you.

I'm confused with the effect DRM has but is there anyway to avoid them? Like if i backup do i just restore them after unlocking my bootloader?
Ideally, i wanted to run a AOSP like ROM and i hoped to remove all Sony stuff etc from Concept, However i'm just reluctant to unlocking my bootloader
This is probably the stupidest idea ever, I have close to no knowledge however what happens if i put Stock Sony 6.0.1 Kernel which has already obtained recovery without unlocking bootloader and flash SuperSU via that?
Alternatively, is there anyway to convert Our current Stock 6.0.1 into True Stock Android

Looking into Android 6.0 Complications from this article (http://www.xda-developers.com/a-look-at-marshmallow-root-verity-complications/)
It states the following:
If you want root today, on Android Marshmallow (6.0), you’re going to need to use a modified boot image. While it remains to be seen if this remains true indefinitely, it looks likely to be the case for some time – SELinux changes make it much harder to get root access without modifying the boot image. And as modifying the boot image requires an unlocked bootloader
Click to expand...
Click to collapse
So i'm assuming Z3 Has SELinux thus preventing us from editting the boot image for Marshmallow Concept hence leaving us with the only option to unlock out bootloader?
Lastly: Is there a potential to convert Stock Sony ROM into an AOSP looking/feeling rom?

want to root & use custom rom!

Hello good people i want to use custom rom !my device is idol 3 6045I as i am noob about this stuffs here is my query :
1. 1st i need to unlock bootloder using fastboot right ?
2. then i need twarp / custom recovery then my desire rom ?
3. what is the best rom currently available ? (my requirement is very good battery life, smooth & stable performance , don't play game that much tho ) i saw lineage 14 available in other sites but not @ xda! really love to use multi screen features ... @Unjustified Dev has 3 rom project i guess! which one should i get or should i try lineage 14! if i miss something please enlighten me ! TIA

1. Yes, Go Here
2. Flash TWRP and Flash the SuperSU ZIP IF ON LOLLIPOP Found Here.
3. 5.1 - PAC as I am currently using right now. Only minor problems are little to no freezes, And if you heavily modify the UI, prepare for some Double FC's here and there. Doesn't happen all the time. But if you feel uncomfortable CM 12.1 is the way to go.
6 - Lineage. Idk about the others.
(Oh, And by the way, do not forget to backup your modem! Some roms are not actually built on from your exact model but they all (6045 variant wise) work the same!)
