Hi! I'm not new to xda, but I just don't get this method http://forum.xda-developers.com/g2-mini/development/bootloader-unlock-t2827748. I don't even know if i have to do this using PC or g2 mini.
I remember rooting, unlocking bootloader and flashing recovery on my lg l7. It was like i download 1 zip file on my PC, unpack it, connect the phone and run 1 file that did all for me. Is there something like that for g2 mini? (D620r)
Hey, i cant uderstand this method too, please tell me if you have found a solution for flashing a recovery in a way i could understand

Never had experience in rooting phones and stuff like that. (totally noob on that)
So I asked a friend of mine to install a custom rom for me.
He installed ordroid on my htc one x +. But there were glitches happening so i asked him to repair my phone.
When he tried to repair it he just deleted the rom and somehow the recovery manager too.(don't know how or why)
Now I can only enter the bootloader. Searched in the google means to flash the recovery and the rom again but no success at all. Tried with the cmd using fastboot and adb.
Does anybody knows how to unbrick it? The methods that i found on the internet all used the recovery manager, that i can't use anymore.
Thanks for the help.

had succes in flashing again cwm recovery.
it appears that the problem is that i can't acess the internal sd card on my phone. I tried to flash a custom rom using fastboot, it gives me this message.
archive does not contain 'android-info.txt'
archive does not contain 'android-product.txt'
error: update package has no android-info.txt or android-product.txt
(I tried flashing a custom rom because I had no succes finding a ruu in zip format.)
So I'm stuck here. Does anyone know if I only need the ruu and flash it with fastboot? Or I'm missing a step?
Hi everyone,
I just bought a brand new Z Ultra C6806. I plugged it into my computer, installed the My Companion software, and then proceeded to root the device via the Chinese root, which seemed to work just fine. I then tried to unlock the bootloader with Flash Tool, but couldn't get Flash Tool to recognize my device. It kept on saying that I needed to install drivers. I'm doing this on a windows computer, and I already navigated to the drivers folder and installed the z ultra drivers.
I then got fed up with that and saw the thread that let you flash a recovery with a locked bootloader. So I followed those instructions and had a working CWM and TWRP. Except then I wiped data and system and flashed the CarbonRom custom rom, and now my phone won't boot at all.
I'm hopeful that everything is not lost since when I hold volume up and plug my phone into my computer I see a blue LED, which I have gathered means that it is successfully still entering fastboot mode?
How do I get Flash Tool to recognize my device? And is it possible to unlock the C6806 bootloader or have I been deeply mistaken all along?
Thanks for any help
[HOW-TO] Unbrick your XZU
You can use method A. Read carefully how to install the drivers and do not use a USB 3.0 port.

so what you've done is to try and flash a ROM with a locked bootloader. You've found out that it wont....
You just need to use 'flashtool' and flash a FTF file.
But like you said before you'll need to ensure drivers are installed properly. flashtool will need to say:
'device connected in fastboot mode' or
'device detected in flash mode'
Download the latest version of flashtool. Then when you select the type of device, you can select Xperia Z Ultra.
and make sure that ADB is installed (windows will detect new device has been plugged in, and if it wont install drivers, you will need to tell it where to find them)

Reinstalled flashtool drivers for z ultra and flashmode and fastboot, pointed my windows drivers interface to the driver file I downloaded from the sony unlock bootloader website and still didn't get anything on my laptop.
Did the exact same things on my desktop and everything is working fine now, flashtool recognized my device, flashed a Sony FTF, unlocked bootloader successfully, playing with CM now.
Still not sure why this is the case, but alls well that ends well I suppose, thanks.
install flashtools driver you can find it in Flashtools folder. PC need driver when xzu in fastboot mode.If you use USB 3.0 like me try different usb slot.

Hi Guys,
My first Sony Phone (previous Samsung User). I have the US Version C6806 LTE model. I have a similar question. I have unlocked my bootloader successfully via Sony's website. I want to be able to install TWRP and backup original ROM before applying custom ROMs. Doesn't look like there is a root available for this phone model yet? I am on firmware 14.1.B.2.257. My questions are:
1 - Is there a TWRP image I can flash on my model via fastboot without having root? Then boot into TWRP and backup the ROM?
2 - If not can I flash any of the images that I seen on XDA via fastboot that include the Root and TWRP in them? Or will those not work with .257 firmware?
3- If none of the options above work can I download an FTF image (older version) that I can root and use TWRP and if so which image do you recommend that would work with my phone model and LTE network on AT&T?
Thanks for all your help and sorry for all the questions I am a noob with Sony Phones. I did research here and seems most of the threads and images are NOT for C6806 which I have.
I think all tyour questions are answered in various threads in the X-ZU forum...
You have gone about it all ass about face, you should have downgraded to .532 then rooted with kingo (looks like is is safe?). Once rooted you should of then backed up your TA partition in case you ever need the phone serviced.
I dont know if TWRP is working well in any of the boot.img but CMR works fine (except for the date of the backups)
any of the firmware/ftf/ROMs will work with any of the Ultras as far as I know

I flashed a .532 firmware still no safe root method from what I can tell. Looks like I need to flash an earlier version or a FTF hopefully that contains root and custom recovery. I will keep reading and researching. Thanks for the help.
do you want to end up on a rooted stock firmware?
as you have already unlocked the boot loader you can just flash one of the kernel/boot img with recovery and then flash whatever rom you want from there...
I also run into Cyanogen Recovery and have trouble going back to FlashTool with my chromebook. I am a bit panicky, but your post is comforting and ensuring.
I got the C6806 xperia z ultra in year 2014. I have been using it as a home primary PC.

Hi! I have the Huawei Ascend G7 and unlocked the bootloader. Then I tried to get root with iRoot and it worked but I don't like the Kinguser App and would like to replace it with SuperSU. That did not work. I read something about Cyanogenmod and custom recovery stuff but don't know where to start and what will fit for my G7. I just want that SuperSU works. Any help? Can someone please give me a step-2-step tut? Do I need to place those images of recovery (don't know which fits with my phone) in internal drive of my phone? For example here it is described something with SuperSU(http://forum.xda-developers.com/showpost.php?p=57896700&postcount=17) but the sentence "After extract Find the way how to use the fast boot you can flash cuatom recovery and then after root flash the stock recovery" is kind of confusing. I only manage to reboot the phone with those commands via CMD.
Hope someone can help! Thank you!!!

Hi! I've managed to brick my device (d610ar) badly, i think
the device doesn't boot normally (message "Secure booting error! Cause: boot certification verify.", and i am stuck there), can't charge it with the wall charger, and the only thing that works is download mode; but flashing a kdz with LG FlashTool (the way i went back to stock a few times) says flashing and at 2% (or 3% sometimes) it says that doesn't find the device, that i have pull out the battery to reconnect my device again and when i do that it does the same thing on a loop, asking to do it again later..
the funny thing is that it appears on device manager on windows, on com port 11 for example, but the FlashTool doesn't recognize it..
so, i can't flash any kdz and doesn't boot.. i've read around here in xda to enter fastboot to fix it, but.. can this device enter fastboot? i couldn't do it, tried adb too and couldn't make the device visible..
i, before this happened, had multirom installed, rebooted to recovery and deleted secondary roms to install in primary rom cm12.1.. there started to happen strange things when rebooted normally to configure it..
after a while trying to boot found around here in xda too that i could enter twrp recovery via hardware keys to reinstall again, so got into it and installed a flashable zip to come back to stock KitKat directly, that have worked for me before..
after that rebooted and i can't do anything else than download mode..
i kinda figured that the problem must be that multirom injected the boot sector after installing the stock flashable zip, and when i did that restored the stock aboot and abootb (these, modified carefully, allowed us to unlock bootloader and flash recoveries, etc, etc.. ; by the way, many thanks to the devs that discovered it and made the guides!)..
now i have read the instructions for flash via fastboot the stock boot.img and so pass the security verification, but i can't enter it..
so, what do you think that could be the next step? or is it really hard bricked and i should forget about it? i'm really hoping to recover it but i don't know what else to do..
sorry for the bad english, not my primary language
thanks for reading and i am hoping to hear some suggestions!
He is not hard bricked you need to flash stock boot and reunlock bootloader if you have custom recovery still installed, but go first with the eazy way search xda about lg flash tool stuck at 2% there some guides to help you get kdz flashed
Thank you very much!

Thank you very much! You made me realize why wasn't working..
Because of you, i started to search threads related with the "flashtool stuck at 2%" and one of the things to look at was a txt file to see what was the problem.. there i found out that the lg FlashTool recognized my device as LGD618..
That's when i realized that i must've messed up when i flashed a lollipop flashable zip for the D618(a while ago), "converting" my cellphone on that model.. so when i connected on download mode and put the LGD610 kdz the comparison of cellphone model and binary model didn't match..
Solution was to flash LGD618 kdz, boot up normally, install towelroot, install supersu, edit a line on build.prop
from persist.multisim.config=dsds to persist.multisim.config=none
rebooted and that's it.. everything works perfectly now! i won't be doing stuff to it for a while
probably will stay stock like that, because now i will be using an OnePlus One in a few days and the G2 mini will be used by my mother, i think..
Thanks again! You saved my device for being bricked forever
i glad i could helped you :good:
I tried installing kitkat having installed lollipop and did not work, also I tried installing lollipop and nothing. Well I think this update lollipop are adding some kind of lock to disallow downgrade or upgrade by KDZ. I try other methods, unlocking bootloader, and install a aboot.img, bricked my phone. I recommend that you do not attempt to unlock the bootloader and install any system image that is not official, or may end up with a dead device.
I was going to try and put the new 511 rooted on , but my sd failed and on reboot can't do anything, no TWRP no nothing except I can get into Flash mode
I have looked around and it is suggested I can put a custom rom on , but the one I have doesn't have*.img files it is a zip with METADATA etc inside.
I am on a uk SGP311, where can I find a decent rom that I can put on using fastboot method only? I want root and CWM or TWRP and was looing at 511 versions.
Any help please to a source for a ROM in this format and a tutorial how to put on appreciated
I don't understand what all the POLLOX stuff is about... can I use these roms?
THANKS
Hi.
Did you unlock your bootloader ?
Is your Xperia Tablet Z LTE (pollux is codename) or Wifi version (pollux_windy) ?
