Turbo Unbrick for Android 4.4.4 - 5.1

[ilia3367]

How can i put my device in this mode to unbrick it?

I can give a script that will put your phone in this mode. The main thing that you do not put a brick in his pants!

Please!

just a dumb question. if i were to hypothetically flash a blankflash on my turbo, then flash another phone (nexus6) gpt.bin and the phone bricked would even the lollipop versiom be able to save it? upon much consistent advice to not do so, i have not done this, i am just curious. thank you for this unbrick.

Added full UNBRICK 5.1. Use with pleasure! Good luck! :highfive:

Too bad we can't use this to reprogram the turbos to be the xt1250 so that the bl can be unlocked.I bricked my phone purposely to try and flash the XML of the moto maxx and it will only let me flash the system for the turbo.It does unbrick your phone though,did it 3 times in a row so it definitely works.

so would the result be the same flashing n6 on the Turbo? brick then unbrick? I ask because the only clue I have found (aside from extra entries in fsg (shamu and quark files akin to the ghost and obake found on the droid maxx fsg) is looking at the turbos make file and seeing that it starts with "little fish". my curiosity has the best of my logic. still reticent to pull the trigger, though.

I tried flashing the nexus files,the xt1250 files to the turbo after I ran the unbrick file but it would not let me,I kept getting an error about preflash validation.That's after flashing the maxx's gpt and bootloader.Nothing would flash besides turbo boot image and system.I can flash the maxx gpt and boot loader but everything else after fails.If you have any ideas let me know and I'll try it.We're basically unbrickable now so I can try whatever comes to mind

How would You not want, all the same you won't be able to flash anything else, except intended for TURBO.

 

[kitcostantino]

my idea was to flash the nexus gpt and bootloader, but im pretty sure it will do the same. the nexus doesnt require server-side approval to bl unlock. if it flashes the bl, though, my fear is it will not allow downgrading to the turbos
and as @ilia3367 pointed out, if its not a Turbo file, likely it will kick it out. who knows.

The boot loader can be downgraded from 5.0 to 4.4,it's the gpt that can't be downgraded.I've flash every version of boot loader from all the maxxs and the nexus 6 it's the partition table that can't be downgraded

Same apq8084 bootloader,same gpt,but systems won't flash.unless someone can make a mofo IMG from 1 of the maxx variants that we could flash.Bl unlock still won't work as I found out because the moto site checks cid,pid, and the uid which I have no knowledge of how to change or if it can be changed.Maybe w/JTAG????

 

[kitcostantino]

I had looked at the sigmas and a couple of other ones, but none have apq8084 support. cid is why I had been so hung up on n6. that and the turbo kernel source's make file starting with the line "little fish" like moto was just saying "here it is".

I honestly have to re-read the order of operations for bl unlock again. im sure there are more holes in my theory than that, even on a N6.

The good thing is we have unbrick. I think we all owe @ilia3367 a big thank you.
edit: just re-read that. so if we sould somehow do a complete flash (I know sig checks kill that) then n6 might be viable.

edit 2: re-reading the bl unlock bible. http://blog.azimuthsecurity.com/2013/04/unlocking-motorola-bootloader.html well, and this: http://newandroidbook.com/21-Security.pdf

Ok simple question here if your on 5.1 could you downgrade to 4.4.4 if this would work then.I could get root

 

[kinglove1211]

The unbrick tool is for fixing a corrupt bootloader,when you updated to lp it also updated the security partition which won't let you downgrade your system.You could flash a 4.4 bootloader but anything else will fail.Also when you unbrick you have to go back to the system number you were on before you bricked or you'll be stuck in bootloader mode with no os.

Once you go to lp you're stuck till root can be found.Hope jcase can get sunshine to work.

I have a XT1225.
I wanna to change somethings on the bootloader, and flash it to the phone.

Question's... If i brick my bootloader, with this change image of my, this tool can be used to fix the XT1225 AKA Moto Maxx?

And will this have anny set backs?

Like that security lock that prevent me from go back to 4.4.4 or somethings like that?

I do have a bootloader unlocked device. But still want to test somethings...

:good:.

Right,it won't let you flash kitkat system,don't look at it so much as the bootloader not letting it downgrade,it's the security partition,gpt.bin that really determines if the system can be downgraded.I've flashed bootloaders from all quark phones w/no problem at all,but if I flashed the gpt from lp nothing else will load so I stayed away from flashing that

You're basically stuck on lp unless sunshine can be updated to support the device or someone can find a way to use jtag to downgrade.At least jcase and beaups are working on it,not much hope w/o them

So is there anyway to downgrade theoretically because some guy said he did it I think I have the screen shot
Here I did take a look I really would like someone do prove or disprove this

well, the key to read there is "or even *upgrade" to 5.1" this person wasn't on lollipop if 5.1 was an upgrade.

In the original thread the guy was on 5.1 OTA and bricked trying to downgrade it sand was saying he had success downgrading

that's insanely awesome if it actually happened, bc motos bootloaders typically, even in a bricked state, will not allow a lower version. that would mean some major awesomeness for those stuck on 5.1.1
