GNEX Unbrickable?

First, pardon my ignorance on this matter. Since Google released the factory imagines for the Galaxy Nexus does this allow you to restore the phone no matter how bad you brick it? Thanks in advanced

Pretty much, as long as some how you dont break fastboot

thanks, I was deciding on whether I should flash YAKJU on my YAKJUXX, knowing that there is a way to fix a possible mistake is reassuring

Well to do that you need to flash the bootloader.
If you screw up flashing the bootloader (like unplugging the cable when it's transfering the file), then you're dead.

Exactly.
On some of the SGS phones its possible to mod them to be unbrickable. Basically you can make it so it boots via USB (at least that's what I understand it to do)
http://forum.xda-developers.com/showthread.php?t=1310865

Actually fastboot is a very safe protocol, it checks for sums before sending and before flashing so that the image is still intact. However if your bootloader is already corrupt on your computer or you dd (flash) some crap into the bootloader partition, your phone will be bricked.
I know a guy who wanted to return his HTC Desire HD. He replaced his bootloader with a porn image. I don't think I have to mention that the phone did not boot anymore

What is the method to fix a phone that is in a boot loop or something else.

No phone is idiot proof and as a previous Galaxy S II owner I have seen guys flash a i9000 (Galaxy S) ROM to their phone and then wonder why it does not boot and the amount of guys who flashed the partition table which also screwed their phones is unbelievable.
Bottom line is read the documentation and read it again and any questions ask on here and from there you cannot go wrong.

Unlock the bootloader.

I'm wondering this myself... in traditional cell phone lingo I believe "Unlocked" means not locked to a particular provider. However I believe in this case it means the bootloader is unlocked allowing you to flash other ROMs?
Thats my take but I could be very wrong
(Tried posting this right away but have to wait 5 minutes... guessing someone will answer this definitively before I get to post this)

You can flash other roms without an unlocked bootloader, such as on the Razr. However, without an unlocked bootloader, you can't use custom kernels.

Not correct. There is no NAND lock on Samsung devices. You can flash custom kernels even if your bootloader is locked (assuming you have root of course).
All that an unlocked bootloader gives you is the ability to flash or boot images using fastboot.

If you are running 4.0.1 or 4.0.2, you can get root without unlocking your bootloader. Not the case on 4.0.4.
As mentioned earlier, unlocking can refer to two things: unlocking the bootloader or unlocking the carrier lock. In this case, we are talking about the bootloader. Most GNex devices are sold carrier-unlocked out of the box.

I've edited the app description to clarify this. I thought I had made it clear on the xda post and at the top of the app description for giving credit to bliss. The bootloader is still very much locked, but we have this working exploit thanks to loki. What I did was just build loki into cwm, so instead of the rom dev or kernel dev having to run the loki patch on their pc, now everytime someone flashes a zip or uses adb sideload their boot and recovery partitions are checked and lokified if needed. This just automates the loki process slightly. Freegee also makes it a little easier to flash these modified recoveries and disable the wallpaper (lge security) if someone wants to stay on a stock rom but just debloat it.
So please do not misunderstand, I just re-implemented loki. Please edit he thread title to indicate it was loki.

i guess i dont understand? you guys could have had roms ages ago with 2nd init recovery. you could have had true cm ports with loki recovery. nothing has changed, there is two ways a device has development on it, either teh people who have it step forward or they find a dev who is interested.

Shabby is right. We could have had roms from the get go but no one either knows or wants to build. I was in the process of learning but LIFE showed up at my door and I had to take care of that first. Now that I'm single and living alone, I could get back to being a creep that lives in a basement(literally in a basement apartment), and try to learn how to build Roms.
Shabby I have a question: Is building Roms pretty much the same for all phones? Generally speaking that is. Because I will no longer have this phone much longer.

Please Help

yes, for the most part building is building. get your build machine set up, sync a repo, edit some manifests and makefiles, configure, compile! obviously there are device specific things when you are trying to debug but the process is basically the same for any cm based rom once teamlgog has the cm bugs worked out for camera, by, etc. once our cm is pretty stable I'll start putting together some roms if someone else doesn't beat me to the punch.
if you want to put together custom roms based on stock there are a bunch of guides in various places across xda on deodexing and using the kitchen, etc to modify resources and add/remove apps and features. and if you want to play around with custom kernels, there's a thread in here to get you started. good luck!

[Q] Unlock N5100 Bootloader

Hi,
Apologies if this has been asked before, I have searched the forums and google but not found the specific answer for the N5100. There are so many warnings about flashing a custom ROM without an unlocked bootloader and how it will brick your device that I haven't flashed one yet. My question is, is it absolutely necessary to unlock the bootloader and if so, how can I do it? There are no links to N5100 specific tools to unlock it and I can't find a way using any of the toolkits or utilities. There are custom ROMs available for the N5100 so people must be flashing them, right? If so, how did they unlock their bootloaders?
Thanks,
Coj

Thanks for the reply. Yes, I also used this to root the device. Does it also unlock the bootloader as it roots? It didn't explicitly say so, I thought they were two separate things I had to do. Is there any way I can check if my bootloader is unlocked?

this is the device information shown in toolkit, it suggests the bootloader is still locked. Is it?

I didn't have to do anything except CF AutoRoot then flash the recovery. However, I have a 5110 so hopefully someone here can validate for you just in case.

OK, so I took a punt and flashed knowing that I could brick my device but lack of specific info prompted me into it. It worked and I'm glad to say and I'm now running a nice custom ROM. One more question, is there a repository for stock apps on here?

Magisk way of rooting - how to get boot.img?

As some of you certainly know, Magisk manager has capability of rooting system.
The needed thing is kernel image, boot.img, very the same which seats in the device.
If the stock ROM was available to download then the kernel image would be possible to obtain by pulling it out from the ROM file (preferably zip).
So where to get the stock ROM file, please?

Here is a link to the Q610TA10K firmware

I'm thinking about the LG tablet I had. No root for it so someone did the Magisk thing also. Tablet was easily unlocked allowing us to put the image in place.
For the Q7, once a boot image is modified how would you get it in place on a running ROM? Far as I know the device is still locked down.

Without unlocking the bootloader this is not possible.
Kingroot, kingoroot will not work on this device atm, I've tried every method possible that's why I gave up on root on this device.
Maybe some day it will but I doubt it.

Sorry, not gonna kick a dead horse.
Even if the boot img could be modified with magisk, there still is no way to install to device without unlocked bootloader.

And have you refferred to this method ?
What do you think of these instructions:
https://www.techdroidtips.com/lg-q7-2018-unlock-bootloader/
especially this:
In conclusion, Android versions later than lollipop come with an option of OEM Unlock in the developer options. So, its quite easy to unlock the bootloader on any latest smartphone devices. And Still, some of the smartphones may not come with this option. Hence, in order to unlock the bootloader, you need to manually do it via PC.

Not on the list

However this list is extremely scarce. It seems something is wrong with it.
This is why wanted to try. The first obstacle is it is impossible to reboot into bootloader (which is needed to obtain device ID). When the command "adb reboot bootloader" is executed then the phone simply reboots into system again. (Attention: when "adb reboot recovery" is executed then it does Factory Reset!)
How to make it boot into bootloader? Is there any keys combination for it?
