Does the hardware on the HTC Flyer check the bootloader's digital signature?
Can anyone answer this?
I am bumping this thread again.
Will someone please answer this question?
It comes from the store locked, but you can unlock it by going to
http://www.htcimeiunlock.com/
They will allow an unlock, but you lose your warranty.

He means if the boot loader is locked, not the carrier. And also to the OP, do you mean read-write access to the boot loader or something else?
I want to know if the first stage bootloader is signature checked by the HTC Flyer's boot ROM. If it isn't then the locked bootloader problem can be solved by simple overwriting it. And yes, read/write access would be required to overwrite the bootloader.

Well i would say no. You can't get a custom boot loader to load 2 roms or anything yet. No access at all, read or write.

No it isn't, it's actually easy to edit a bootloader, it's getting it onto the device that's hard.
I still would like to know if the bootloader itself is signature checked.
well then read my last post.
The only thing your previous post tells me is that accessing the area where the bootloader resides is difficult.
The the "no it isn't" doesn't mean anything?
Sorry. I thought you were talking about simple read/write access.
Master Melab,
PM me is you have specific questions, you can post a summary after that if you want.
I messaged you my questions.
curious about what youre getting at,so subscribing

if its fairly easy to edit a bootloader, is it not possible to patch the HC hboot to think the radio is s-off(like the revolutinary does),then simply install that hboot in place of the real one,when following the HC install guide?
seems after one roots GB with revolutionary,it should be fairly easy to get an s-off HC hboot for someone who knows how to do such things what am i missing?
I've searched all day for info on wether it is possible to install recovery without unlocking the bootloader? Right now all points to not possible, but please give me a deffinate answer.
Thx in advance.

I was looking only half of a day and then got to this post - thanks.... Damn you ASUS for you wicked tricks
I like CWM on my Desire phone... kinda want me riverdancing... void my warranty
Someone correct me if I am wrong but changing out a recovery.img requires bootloader access. Unless a dev can crack the bootloader or the manufacturer allows it, def hard, help that helps.

.21 downgrade & unlock bootloader
The 9.2.4.21 firmwware presently cannot be rooted. The way to get root is to use version 9.2.4.15 or earlier, (I used .11) using a linking trick and then use ViperMOD to complete with root and unlock.
Tutorial by Wolf849 - over here - will get you to .11 firmware and working super user / root access.
Then use ViperMOD PrimeTime by - viperboy - which includes an option to install Clockwork Mod recovery and install the Asus Unlock Tool.
Once the bootloader is unlocked, you can install a custom recovery, such as CWM, CWM Touch, Open Recovery or other as you wish.
Unlocking does have the penalty of voiding any warranty and you might possibly get into a boot loop, which can be resolved with;
Code:
adb shell dd if=/dev/zero of=/dev/block/mmcblk0p3 bs=1 count=13
Roach2010 has a thread here explaining the boot loop issue in better detail and Diamondback has some very helpful unbricking tips.
Hello everyone.
I had posted this in the Z forum, not realizing there was a Z Ultra forum. So I will just quote my previous post and add some info at the end:
Hello guys. New guy here with an Xperia Z Ultra phone.
I'm trying to load the Paranoid Android custom ROM.
Had a couple of questions:
1. I went thru Sony's instructions to unlock the bootloader. When I ran the fastboot -i 0x0fce oem unlock (e-mail code), the first error message I got was "FAILED - Remote - Command did not succeed". So I tried the exact command again, and then I got "FAILED - Remote: The device is already rooted".
I have searched high and low, and cannot seem to find any way to verify that the bootloader is now in fact unlocked.
2. Reading the instruction on how to install CWM/TWRP recovery menus, Every single list of instructions includes the following "This tutorial is only for Sony Xperia Z Ultra with 510 and 493 LTE firmware. Do not use it for any other carriers or variants"
Again, I have searched high and low to find a way to confirm what firmware version I have. All I know is I have the C6806 model, with the build number: 14.2.A.0.290
So can someone please help out a very confused guy here? I don't want to brick my phone by accident
So far it's still working ok

So far, after doing some major searching, I seem to have found that I currently have "290" Firmware, and that this Firmware is currently NOT able to be rooted. Is this correct?
Also, I still have not found a way to verify wether the boot loader actually did unlock or not. From what I have been able to read, it seems that if a proper boot loader was in fact, unlocked, it would have wiped all the data on my phone along with the SD card data.
So far, it seems everything on my phone is intact. So does this mean the boot loader unlock command failed for me? If so, why did I get the reply "this device is already rooted?"
I can't believe how difficult it is to root a damn Android phone! Jailbreaking an Apple device is 10 times easier!
First of all, it's usually pretty easy to root Android devices. In most cases it's only a simple click, but sony has done a good(?) job at fixing exploits, so it does it much harder for us.
Second, you can check if your bootloader is locked or unlocked by opening the dialer and insert *#*#7378423#*#*, go to "Service Info" and then "Configuration". If your bootloader is unlocked, it should say "Rooting status: Bootloader unlocked: Yes". It's easier to use Flashtool to unlock the bootloader if you're having issues using a terminal.
You'll find the rest here (including bootloader unlocking). If you need some help, ask in that thread.
If you aren't boot loader unlocked then "BACKUP TA PARTITION" from My Lord's guide @LordManhattan
Just incase you need to re-lock it for service

First of all it' pretty damn complicated and unrewarding to root a Sony device. Not all android but Sony definately. We checked, bootloader is unlockable. We unlocked and relocked bootloader prevoiusly because there is no robust, easy-to-install ROM for ZU. But time to time we try to root it.
Now, the question is the same: what should we do to re-unlock the bootloader if anything is OK, but flashtool says "Command did not succeed" for the first time and "Device is already rooted" for subsequent times at unlocking?
Please write some advice about the question, not about TA backup and your success. Thx!

Oh, are we demanding help now?
Bootloader unlocking is a straight forward process. I've had a couple of strange errors in Flashtool while trying to unlock the bootloader, but just close Flashtool and try again. Also be sure to be on the latest version of Flashtool.

No sir, not at all. I wrote please, no demanding. Well yes, I'm a bit picky because there were no answer and I usually find some on XDA. Besides I used custom roms on Samsung devices for years (SGS2, SGN, SGN2) and I was disapponted when I bought my XZU that there are very few roms and I couldn't use them (I managed with very hard work to go back to stock in 9 hours after unsuccesful flashing).
So there is some basic problem every time. Like trying to root but cannot re-unlock because of some mysterious errors with no solutions.
Enough of my problems, your answer is much appreciated, will try to re-unlock some time. Thx!

Oh, i get that. I came from Samsung myself, and this is my first Sony device ever, so I've had some issues myself. I've gotten the same error message(s) as you before, and i think i restarted Flashtool and rebooted my Ultra and it was back to normal again - i think, but it "fixed itself" after trying a couple of times, so don't give up. It's also important to always be on the latest version of Flashtool.
It would also help us if you could tell us what you're trying to achieve, so you don't end up spending 9 hours on something that takes 5 minutes
@Champdor
From what I can make out you have never managed root your phone or back up the TA. If the latter is true then there is very little point in relocking the bootloader.
Yes the process is a little harder than Samsung, but the last device I rooted was a ZTE, and that was even harder to root and flash from what I can remember (yes this is my first Sony device as well, and I will buy another...)
Take you time and read the stickies that we have written and all should go well. Don't be afraid to ask (intelligent) questions if you get stuck, and read some more

I have not had this error so have not tested this, but what happens if you flash a full FTF and wipe everything then try to unlock the BL?
And remember that you can take a backup of the unlocked BL (re member to name it as such) and just flash that to unlock again. Doing it this way you don't get the format that happens when using the unlock code.
I followed this post to downgrade, root, i use Backup TA v9.10 to backup DRM Keys, use Flashtool 0.9.14.0 to unlock Bootloader, then to flash other Rom's (stock and customs), came back to Stock Rom .681, relock the Bootloader with Flastool 0.9.15.0 flashed the last .757 and unlock the Bootloader again with no kind of problems using Flashtool 0.9.15.0....

You just back it up as you would for a locked BL. Just remember to make sure you name them well so you know which is the locked one and the unlocked one.
NEVER use a TA backup from another phone, you WILL HARD BRICK IT

Hello , i want to root my phone z ultra 6833 .757 i watch this video youtube . com/watch?v=uFSeSe8gQOY
i unlock bootloader after this install 757.img by flashtool so i can open recovery but after this i didnt find the same file he run i try run supersu.zip but the phone havent rooted plz what the problem
Hi, I literally opened the nexus 9 out of the box, powered it on & after choosing a wifi network it began updating, the device crashed during this update and now it won't boot! I've tried & searched for everything, anyone have any ideas?
Booting to recovery with HW buttons, wiping cache/userdata/factory reset - Nada!
Can boot into fastboot, no permission to flash as oem unlock is disabled!
I cant get into the tablet to unlock fastboot oem unlock within devOpitons or usb debugging etc, (com.android.phone has stopped on boot) black screen indefinitely.
I can't flash any images while it is locked
surely there must be a simple method?
desperate here
Return it
I'd just return it. I'm no expert, but I'd seek a way to avoid the update during setup and try to postpone it until you unlock developer options and OEM unlock. I'm not sure how you'd bypass the update during setup, but you're in the right place if it's possible.

If I remember correctly you can still flash the stock images even with the boot loader locked. Its only custom images that google will not accept unless you unlock boot loader.

Bootloader has to be unlocked to "fastboot flash" anything.
You can sideload an OTA with a locked bootloader, but you have to be able to access recovery.

Indeed I'm still new to nexus devices. I've been flashing on Samsung devices for years so I'm still stuck in my Odin ways. Just got the N9 less then a week ago. The whole fastboot thing was foreign at first but I'm getting there lol. Thank you again.
Hi all, I have a problem,so I aks for a little help. I was unlocking bootloader to follow the guide for rooting but when I use flashtool to unlock the bootloader I can't put the unlocking code received from Sony cause flashtool open a windows where a code of 4 number is prewrited where I have to put the Sony's Unlocking code. And naturally I can't overwrite/erase it. Is some way to fix possible?
Thanks.

Strange. First thing to do is update Flashtool. Then try with new version.
I haven't used it to unlock the bootloader for a long time, so can't really remember the details, but I know it worked fine, and stored the code.
Maybe try double-click...
Hi,updated flashtool but not solved,also trying other solutions to modify the code but still not possible. >_<
Finally unlocked ,thanks for help.
