[Q] Ways to get new bootloader - Sony Xperia Z Ultra

As some of You may know, Sony gives as opportunity to use /recovery partition.
My question is if I still need to use EMMA or some update (.270, .283 for Tmo) has this bootloader built in?
I ask, coz I read (maybe its just gossip) the M2 with 18.3.1.C.1.17 got new bootloader (ofc it still needs unlocked bootloader to flash recovery).
Additionally i would like to ask someone who use it, how to flash recovery to this partition.
And what when i flash stock rom. Is it overwritten? Or recovery is always there?

I think recovery isn't flashed unless you flash it, because even flashtool doesn't do it.
Recovery can be flashed through fastboot using "flash recovery xyz.img", where xyz.img is your recovery but you have to compile one yourself as I haven't seen any already compiled.
Sadly, none update has integrated this bootloader update so far, maybe sony will surprise us with the 5.1.1 update and include it so yes, you have to use Emma.
EDIT: You can download AOSP package from freexperia, they have build an AOSP recovery that you can boot into with the new bootloader but the menu is missing, however I can be wrong because I have tried it a month ago, maybe some changes were made

Can't access anything

So, I think I finally did it. I broke my phone.
I wanted to flash the new Existenz Rom 6.0 and the flashing worked fine. The phone started and it got stuck in the Xperia logo. I than downloaded the Bootloop Fix. To make sure nothing goes wrong I wanted to do another factory reset. Somehow, my phone uses two roms (Philz custom recovery or something like that (I flashed the rom with this) and a TWRP Recovery). My phone booted into the TWRP (which it usually doesn't do) Recovery and I thought "Well, I can do a factory reset here". So I did the advanced reset but after restarting I can't access anything! When I turn it on, there is still the Sony Logo but if I press up and down I can't access none of the custom recoverys. I'm truly desperate and I can't afford a new phone. Can someone help me how to fix this?
@DerDokktor
XZDR and similar recoveries for locked bootloader reside in /system partition , when you wiped your system you also wiped the recovery...
You'll need to flash an .ftf firmware with flashtool to recover your phone. If you want root and a locked bootloader flash a KK or LP ftf (as MM is not rootable yet), then root it with kingroot or something else you like, install XZDR from your computer and then you can go to the recovery again and flash existenz rom or any prerooted rom you want.
You could also flash a MM .ftf directly but then you won't be able to root it without unlocking your BL.
If you need help with flashtool follow this guide:

Edit: the first steps of this guide are to create your own .ftf , if you already have an .ftf downloaded you can go straight to the "Now that the FTF firmware file has been created, you need to flash your Sony Xperia device." section of the guide.

Note 3 [SD] came with unlocked Bootloader

Hey all!
I just got my Note 3 (Snapdragon/Kenzo) from DX and it came with global US rom. I checked and its bootloader is already unlocked. I want to update to Miui 8 global dev but I'm worried with this unlock, is there a way to know if it was officialy or unnoficialy unlocked? I want to flash the oficial recovery rom but heard that it can brick the phone if it was unnoficialy unlocked.

It came with Miui 7.3 Stable (7.3.2.0.0 LHOCNDD)
Please, help. =)

That is a vendor rom.
More than likely it is unofficially unlocked, because your only allow to unlock 1 device per month for each account.
Since your bootloader is unlocked, flash an official rom (which might lock the bootloader again).
Don't flash the latest 6.0.1 rom yet as you might not be able unlock with that.
Then unlock officially.
Check the reddit xiaomi wiki for guides.
Got it! Thanks, for your answer. I realy dont mind unlocking, I just want a miui 8 dev(it has a built in root, right?). I just was afraid of what method of flashing I should use with this unnoficialy unlocked bootloader. I'm going to search this wiki for it.
And better do a Alka TWRP backup now, before anything! Then, if you get your bootloader locked, you can always restore the backup to your current status - ROM and unlocked bootloader. I have two Kenzos in the same situation, and that's the way I do it.
Nice! Will do. Can't I just use that recovery to install an updated rom? There is an annoying bug on this version, I can't open my contact or dialer app, they close befero they appear on screen, tried erasing data but no help.
Boot from TWRP without installing it, make the backup (all partitions), then make sure you get the backup on your PC. After that you can install TWRP and make whatever you wish.
And don't forget, if you need to restore, do it without restoring the firmware partition, or else you'll get an error.
Thansk! But I think I will stick with the global dev. Can I flash it via Fastboot (MiFlash)? This unnoficial unlock wont cause any trouble, right ?
This is not an unofficial unlock. Is isn't either official
My phones came with some vendor MIUI's - 7.4.9.0(LHOCNDD), respectively 7.4.18.0(LHOMIDD), but I never flashed another MIUI, just custom ROMs. For what I know, if you flash via fastboot it will wipe the entire partition structure, including boot and recovery, and the bootloader will get locked. In that case you can not restore the backup you make now. You'll have to apply for official unlocking, or go unofficial.

that means.. you recieved an unboxed device, may be refurbished, repacked and resealed and sold $25 costlier than the original. :silly:
Not necessarily. I have two, buyed from a local big online store, both came with unlocked bootloader. Both boxes were sealed, with no sign of foreign hands
I have 7.3.2.0.0 LHOCNDD rom and unlocked bootloader. Can I just type on fastboot:
fastboot flash recovery recoveryAlkaUpdate.img
to get twrp(alka)?
Thats work!

I have the same MIUI vendor as you, 7.4.9.0(LHOCNDD), what method did you use to install TWRP? I only want to install AOSP/CM based ROM on this device. I want to flash it ASAP cause this MIUI ROM have a Trojan downloader, which luckily can be disabled.
I used Cofface on first phone, Alka on the second. Before flashing, first boot from TWRP image, make backup of all partitions to the SD card, copy the backup on computer, and only after that flash the TWRP image. After that... flash ROMs

I followed a tutorial that uses ZXC TWRP while on MIUI. Then I flashed ALKA, I'm on Nexus Experience now.

Bootloader Unlock = No after Restore.

I have a Z5C(E5803) that was originally able to unlock the bootloader and let me flash ROMs, specifically the Cyanogen ROM that CTXz has been working on. I ran out of power and got stuck in some kind of nasty bootloop yesterday that prompted me to re-flash boot.img and TWRP.
After I did these things I left it charging for a few hours and it was able to boot into TWRP where I then restored it to a backup of the basic Xperia pre-loaded ROM.
This all worked fine, thought I could boot into TWRP and just flash the Cyanogen zip again. I can get into TWRP just fine but I attempt to flash Cyanogen I get an "ERROR 7"
I have since done several wipes, gotten into the bootloader settings by entering that code in the dialer and have seen that bootloader unlock = no. I distinctly remember bootloder unlocking being allowed the first time I installed CM on my device, what could have caused this?
I was able to use it with fastboot anyway and install CM13 again, maybe this was a bug?
When I tried using oem unlock command with fastboot it said my device was already rooted even though I had just restored from a backup, and then I just proceeded normally from there.
use CM13 official Recovery to FLASH CM13.
also i don't think so twrp3.0.2 is out there for z5c. are you using any other variants Twrp? (YUGA ? )

Re-flashing OPX ROM via fastboot

Hi
First a little history...
I recently got an OPX with the intention of installing Sailfish OS on it. So first I need to get CM 12.1 installed. Following the instructions here I flashed TWRP using fastboot, but the version of TWRP provided at the link would not find any system partitions on my device and therefore could not be used to flash any images. Newer versions of TWRP would simply not load.
Eventually, using the stock OPX recovery, I managed to upgrade Oxygen OS to the latest version. I then flashed the latest version of TWRP (3.1.1-1) again and it worked! It found my devices partitions and I could flash ROMs with it. But, it wouldn't flash CM 12.1. Something about a trustzone incompatibility...
So I got the idea to try and downgrade Oxygen OS, which I did via TWRP. But then TWRP stopped working... and here is my problem.
I'm now stuck in a situation where:
- I can access fastboot
- The only versions of TWRP which work (e.g. 3.0.2-0) fail to find my system partitions, and therefore can't be used to flash ROMs
- The stock recovery also seems to fail to find the system partitions (clicking on "install locally" does nothing), so I can't use that to flash ROMs either
So I really need to get a working image on my phone somehow... but how?? Is it possible to do this via fastboot only?
Cheers!
Is your bootloader unlocked? TWRP cannot see system partitions if so.
I unlocked it originally... but since then I have installed a new ROM (Oxygen OS 2.x). Would this overwrite the bootloader? Do I need to unlock again? I think I must be using the old OOS bootloader now...
I think you can see if it's unlocked if you boot into bootloader, connect to pc and write on cmd "fastboot devices".
Whenever you switch between android 5.0 roms and 6.0 and further you have to first use the correct recovery from oneplus, only then you can flash the correct twrp and the adequate roms
My bootloader is unlocked. I cannot flash a new ROM via recovery, because none of the recovery images (stock, TWRP) can see my system partitions (I don't know why). At this stage I would just like to know if there is a way to flash a stock ROM/recovery/bootloader via some other method (fastboot, or a special tool), so I can restore my phone back to factory state. I don't care about losing data. Thanks.
EDIT: Just to clarify, I believe this is my current situation (please correct me if something doesn't make sense):
- OOS has two different bootloaders, 2.x and 3.x.
- The phone originally had OOS 2.x on it. None of the TWRP images I installed recognized my system partitions, so I couldn't flash with TWRP.
- After re-installing the stock recovery (which happened automatically when I booted to the stock ROM), I was able to upgrade to OOS 3.x via stock recovery. Now recent TWRP versions were working (I assume because upgrading to OOS 3.x updated the bootloader too), and were recognizing my system partitions.
- Using a new version of TWRP (3.1.1-1), I re-flashed an older version of OOS 2.x again. I think this was my mistake, because I think this downgraded the bootloader to 2.x again. Now none of the TWRP versions recognize my system partitions, so I cannot flash ROMs.
- I have re-flashed the stock recovery from the OnePlus website, but not even this allows me to flash ROMs. The symptoms look like in TWRP, i.e. that it fails to recognize my system partitions. So I am stuck with no way to flash ROMs, or upgrade the bootloader.

Root lolipop stock ROM

How i can root lolipop stock ROM of lenovo tab 2 a7-10f ?
I have tried kingroot and much more methods, but doesnt support.
I heard people say that lolipop version cant be rooted, just kitkat version which is first ROM. Lolipop is OTA upgrade from Lenovo.
I dont want to flash ROM, i want to use some tools which are available throught root.
I have tried flashing TWRP throught unlocked bootloader (fastboot), when i run command:
fastboot flash recovery c:\twrp.img
It says, done.
But i cant eneter recovery, and i flashed it multiple times, and it says it flashed fine.
But when i use key combination i enter in stock recovery.
And i tried diffrent command (i didnt know that command is bad idea)
fastboot flash boot c:\twrp.img
And i stucked in twrp recovery, it coudnt boot in normal system, because i changed what android should boot.
I extracted from stock ROM, boot.img and flashed it only in fastboot.
And booted normaly, but when i run on recovery, i saw i deleted it's stock recovery.
I was freaked, and i didnt touched anything anymore, i lost stock recovery but i dont care, i care that tab is still alive.
I'm not able to flash anything in any other way that fastboot which is quite scary to use if tab is working good (i dont want to break if something works)
How i can root it.
I have knowledge of adb commands but with all that knowledge i didnt managed to get root to this device, it looks like it's locked in that way.
Lolipop is best, it is very good and accesibile, and i just want to tweak it more with some xposed modules and apps that support root.
