[Q] Is the nexus 4 unbrickable?

Hey guys,
Just ordered a Nexus 4 online and waiting for it to be delivered. But had to ask a quick question, that is, how easy is it to brick the Nexus 4? And if so, can it be unbricked easily via software?
I am currently using a Motorola Defy + and it its almost unbrickable and can be recovered from any type of brick. So just curious

Flash the wrong kernel is a really easy way to brick your nexus 4,and the only i know

Yep worst you can do is flash a kernel or ROM meant for a different device, but even that can usually be recovered by using download mode.

You can easily recover if you have a nandroid backup though I think.

Fastboot erase bootloader will brick you pretty quickly

In short, you really have to try to brick it. Even then, it takes some work to break it to the point that you can't fix it with fastboot. You won't hard brick it on accident. I don't consider a soft brick a brick of any sort when you can fix it in 15mins with fastboot.

Pretty much the only way to brick is flashing the wrong bootloader or flashing something that isn't a bootloader to the bootloader partition.

In a way yes. Although it isnt like samsungs download mode, it is kind of unbrickable if you do brick it you just go into the bootloader use a toolkit download the stock rom and it will do the rest for you

Thanks people. Much appreciated

There is a topic somewhere in these forums with a guide that uses a program called lgtool or lgetool (can't remember which)
Which even lets you recover from a bricked bootloader. Though it is a lengthy and technical process.
So at this moment it is physically impossible to brick your phone. Unless it is bricked from actual damage to the hardware

Yes there's a great guide by Gigadroid somewhere in the general section. Basically as long as you can get into download mode the phone can be recovered.

Yeah I don't understand why people view flashing a wrong kernel as bricked. If you can get into the bootloader in my opinion it's not bricked!
Bricked is when it's just that, the phone can only be used as a paperweight and doesn't turn on in any sort of fashion. So doing "fastboot erase bootloader" is what I call a brick, which you'd have to be really drunk or just a total moron to do. And flashing wrong bootloader, or being so lucky as to have a power outage in the spilt second it takes to flash a bootloader is one of those I view as brick.

Maybe because if you flash an incorrect kernel you can't boot into the boot loader? Just a thought.

When does that happen? I've never had that happen. I just purposely flashed a wrong kernel and i can still get to bootloader and recovery...

I saw a thread where someone flashed nexus 7 kernel on the nexus 4 and he had to buy a new device,but maybe Gigadroid wrote the guide after that thread

I remember accidentally doing that on my galaxy Nexus. But twrp actually caught it and wouldn't allow me to install it. Kept errroring out.

This isn't a true fastboot command
But yes, this is a very hard device to brick, most everything is recoverable. But I'm sure there are plenty who find a way to do this, usually the ones who dive in head first and have bad luck.
Just be sure you read and understand before you try and beg for help

Have you actually tried the command.
On the nexus 7 this was a valid fastboot command and there was a few instances of people bricking by erasing the bootloader then rebooting before flashing another one
It probably would be a good idea for Google to have removed the ability to erase the bootloader as there really is no need to erase it

WOW after i sold my s4 and got nexus 4 im even loving nexus moreeeDDD i wish nexus 5 is awesome as this DD

how can i fix it ? and why i have this problem i flash my phone many times and this is the first time i hace this problem
thnx

Try going into the stock recovery and wiping the cache. If that doesnt work, do a factory reset using the stock recovery.

I tried do what you suggest but still don't work :/

there any different between the versions ? 48/54 and 84

Not much I've used all of them. When I flashed 4.3 I did it with images from the Google page in bootloader mode. I updated all my Android pc software "I use Windows". I locked and unlocked, then flashed in bootloader. I had one issue I missed spelled something but very thing went well

Try flashing the 4.3 baseband and see if it loads. If it does then I suggest you use a hybrid baseband by morrislee.

[Q] anybody knows a method to step back from 4.4.2 to 4.3

Hi @ all
Does anybody knows a method to downgrade from the new bootloader aka KK 4.4.2 to JB 4.3?
The phone is rooted and a custom recovery is already installed.
I already tried this methods:
For the first only flash a custom 4.3 rom. Surprise no success After restore tried with an official fw by Odin without pitfile (anybody tried this?)
Surprise surprise no success.
Then I tried to unlock the bootloader cause I read that this one is locked. So I used adb with the following cmd lines:
Adb reboot - bootloader phone boots in dl mode
Then I typed fastboot OEM unlock and fastboot shows in cmd waiting for device. The phone driver are already installed in sdk, from official samsung USB driver and the Google adb USB driver. Phone where detected in adb but not in fastboot. U can check this if you type fastboot devices...
So this is what I tried. Does anybody have other solutions that we can try?
Does anyone know how to detect the device in fastboot?

and no no downgrading

NO, for the 100th time.
Don't you people read? *sigh*.

I already read every post and everywhere the only answer no but nowhere I can read something about let us try this or that. Sorry for annoying you but if you don't want to try to get a solution for that you better not post.....

It's already been stated hundreds of times that it is impossible to downgrade from 4.4 to 4.3 because the latest bootloader sticks the device to 4.4.

Exactly the same says everybody in the galaxy s2 Foren when 4.0 came out and they want to downgrade to any firmware befor this. It took a while but there was a solution found. So I asked here if anybody tried anything to test if we really stuck on 4.4.2.
Maybe there is a simple way to unlock bootloader and use the files from nexus 4. They got a solution for the downgrade procedure. They unlocked the bootloader and flashed by fastboot a file named flashall.bat. so they where able to flash fw befor 4.4.2. So you see it is possible to do it!!

Oh man does anyone read the first post. I need a bit help with the fastboot driver. It does not detect the phone. That's why I asked for help not to become stupid reposts that it is not possible. I think no one of you tried to get a solution!
And when there came someone who asked for help nobody reads the op and get stuck on the first sentence. DONT POST ANYTHING IF YOU ARE NOT ABLE TO HELP. I KNOW THAT AT THE MOMENT THERE IS NO SOLUTION BUT LET US TRY TO FIND ONE!!!

If your phone is rooted you can enable fastboot. There is a script in the dev section on how to enable fastboot. As for downgrading and playing with bootloaders. You will need to be very very careful, samsung bootloaders don't play nice and you can hard brick very easily.

Couldn't find it. Could you share a link?

[Q] Xt907 Locked Bootloader, Possible to install Cyanogenmod or Roms with Safestrape?

As the title says, I am wondering if I can install the current Cyanogenmod (file: cm-10.1.3-xt907.zip) with Safestrape/TWRP. My system version is 98.15.66.XT907.Verizon.en.US, baseband: SM_BP_101031.027.32.81P. I am aware that I have the OTA update that locked my bootloader, nulling the use of motopocalypse.
I did try flashing a Cyanogenmod build to Slot 2 of my recovery which ended up softbricking my phone. I might have messed up something during the flashing, or perhaps didn't change a certain setting.
The Safestrape version I have and used is 3.11, the latest build for my device is 3.12. Would 3.12 be any better when flashing Cyanogenmod?
Any help would be appreciated.

.66 was the OTA prior to the one that locked the bootloader. .78 locked the BL. Try to see if you can unlock.

System version 98.30.1 XT907 Does anyone know if my version is unlock able or not?

Thanks, but the question remains. Is it possible to install CyanogenMod or other Roms with Safestrape/TWRP? I tried flashing it once again, but after I select reboot phone, it remains black. I have to do a hard reset on my phone to get it to recovery to restore the stock.

TWRP is for those of us with an unlocked boot loader... You can use safestrap sure... Not to many roms for it most all is stock/stock based... There is a old cm ROM you can flash in safe strap but it's an older one and I think the camera was broken... There is topics all over here about what you can do with a locked boot loader... Have you tried to unlock it yet...

[Q] Stuck at Bootloop[Urgent]

Hey fellas!
I am actually a N5 owner and using it without rooting it for past 6 months and pretty happy with that.Before N5 i had Galaxy S3 on which i tried a lot of things and learned about rooting,flashing..etc.
Now i have my friends N4 which always stuck at bootloop after update(that's what my friend told me) i tried clearing cache,factory reset from the stock recovery but all in vain.I have no drivers installed in my lappy just for info.
So, what info i have?
in recovery it is showing build no - KRT16S
Bootloader ver - MAK0Z30d
Baseband ver - M9615A-CEFWMAZM-2.0.1700.97
Secure Boot - enabled
Lock State - locked
What can i do?
U tell me!

Flash factory image, latest one

Update your recovery and try flashing again.

Maybe unlock the bootloader and flash the factory image with a toolkit
