Wondering does the new boot loader support older custom ROMs and the nexus toolkit, will I need to re unlock bootloader after flashing it ?

Answered my own questions flashed with cwm still have root but don't know how to check if boot loader is locked or what version I have. Works fine with cm10. :)
[Nexus 7 Android Development] sparksco:
When you power your device on you hold the volume down button to get into bootloader. On the main screen it will say what version it is.

Re: [Bootloader][Android 4.2] JOP40C Bootloader version 4.13 flashable in recovery

I can run the new bootloader without flashing to a 4.2.2 Rom right? Debating flashing the new PA but haven't decided yet, would like top be ready to go though for this weekend when more of them start popping up
[Nexus 7 Android Development] N@th_OC:
Theoraticly you can.

You'll see no direct second effect.

It's more important i think in the other way.

If you use 4.2.2 you have to flash it. (before is better :silly:)

But i see no problem to run 4.1.2 on the new bootloader.

Re: [Bootloader][Android 4.2] JOP40C Bootloader version 4.13 flashable in recovery

So I edited the original zip so I could flash the new version in recovery. Some reason it didn't work.

Looks correct. Someone care to make a flashable zip? The motherboard died in my computer and I'm waiting for Asus to send a replacement.

Geez wouldn't it be easier to just have a flashable zip for all this? Do we really wanna spend pages of multiple threads of this stuff? I am just saying that think we would all be better off having a zip as opposed to non-stop Q&As on fastboot.
[Nexus 7 Android Development] sparksco:
Re: [Bootloader][Android 4.2] JOP40C Bootloader version 4.13 flashable in recovery

Re: [Bootloader][Android 4.2] JOP40C Bootloader version 4.13 flashable in recovery

Actually I have and it seems much of it deals with issues of fastboot. I am not saying we shouldn't learn to flash through fastboot but that much of this could have been satisfied with a simple zip file. I mean if you want pages of Q&A on fastboot, be my guest. I am just trying to help. I mean the title of this entire thread is about a flashable zip for a bootloader? Do I have that wrong?

[Nexus 7 Android Development] SkOrPn:
Well imo we can still use this thread for valuable information regardless if the OP makes zips any more. In my 5 years here I have seen many threads go from active rom or bootloader or kernel threads strictly into help threads. We have threads still active two or three years after the OP's topic has long been abandoned. Its just the way it is.

So, with that I would like to know if anyone knows what changed from Bootloader 4.13 to 4.18? Is there a reason to use one over the other? Just curious...

[Nexus 7 Android Development] sparksco:
Re: [Bootloader][Android 4.2] JOP40C Bootloader version 4.13 flashable in recovery

I don't see what the big deal is. It looks like on some Roms "display" has replaced "screen". As you can see display has the same icon as screen. On my ROM I still have screen and its 4.2.2. What Roms are you guys seeing this on, stock ota?
[Nexus 7 Android Development] fluxthesky:
I flashed the rooted stock 4.2.2 provided by someone on this board.

Before flashing the 4.18 bootloader, I have the 'screen' info, but now I have neither the 'display' or the 'screen'.
[Nexus 7 Android Development] sparksco:
Re: [Bootloader][Android 4.2] JOP40C Bootloader version 4.13 flashable in recovery

Hmm, I'd say it's the ROM your on cause like I said I still have screen under battery stats. Nothing changed for me after flashing the bootloader in fastboot.
[Nexus 7 Android Development] icytrey:
Re: [Bootloader][Android 4.2] JOP40C Bootloader version 4.13 flashable in recovery

[Nexus 7 Android Development] torchwolfery:
hi all im a little lost how exactly do i flash the img using bootloader. I boot into bootloader and i have 4 choices, Start, Restart bootloader, Recovery mode and power off, neither seem to give me an option to flash the image... thanks guys
[Nexus 7 Android Development] fifasarajevo:
if its a flashable zip then you have to go into recovery and flash the zip file. If its just the img file then you have to connect your n7 to a pc and open a command prompt while you have your Nexus 7 set to fastboot mode. Then you can type in a command to flash the new bootloader.
[Nexus 7 Android Development] torchwolfery:
thanks dude some else sent me a guide with a step by step instructions for flashing via computer.. complicated lol
[Nexus 7 Android Development] fifasarajevo:
yeah after you do it a few times it really becomes nothing
[Nexus 7 Android Development] coolek33:
If someone is still strugling with bootloader flash you can use wug's nexus root toolkit. It works like a charm. I've pulled out image 4.13 from this threads zip and flashed it. After that i tried 4.18 from other thread. It works.
[Nexus 7 Android Development] pughie:

[Nexus 7 Android Development] .torrented:
to tell if its unlocked when you get to the Google screen there will be an Unlocked Lock picture at the bottom of the screen and when you boot into bootloader at the bottom of the screen it will say what version it is and if its locked or unlocked

If anybody wants the .img file to manually flash here it is (DO NOY FLASH THIS IN THE RECOVERY YOU MUST USE ADB)

flashed... no problems.
[Nexus 7 Android Development] sparksco:
I really do appreciate the help but I don't see why you feel the need to spam this thread with all your own files. All of the bootloader images are in the stock factory nexus 7 images (which I think there's links elsewhere here on xda for). I already stated this in a previous post (if you read it). This is just more convenient to flash in recovery...
[Nexus 7 Android Development] cale42:
Hmm.. so this is my first try flashing bootloaders.. and I have always used CWM.. but given some of the warning I wanted to try TWRP. So I loaded Scotts deodexed rooted 4.2, then installed goo manager, installed twrp, rebooted recovery and installed this. I flashed it twice. Both times it said Installation complete. BUT when I check my bootloader version it still says 3.41. Good news is it still works fine.. but thoughts?
[Nexus 7 Android Development] Pithism:
i should only flash this if i am running a 4.2 rom correct?
[Nexus 7 Android Development] Travisdroidx2:
I have the bootloader.img file in my platform tools but wanted to give this a shot. Flashed with twrp and worked perfect. I booted into bootloader and verified it is 4.13 and then went into recovery with no issues. Works fine here good job. Just a FYI I am still on 4.12 and the bootloader is working fine.
[Nexus 7 Android Development] brizey:
So, anyone have a change log? I was not aware of any bugs with the last bootloader. They already had fixed the boot without USB bug. Is there any new function? Just kind of weirded by these rapid bootloader changes.
[Nexus 7 Android Development] sparksco:
With every major platform update you can expect a new bootloader as well. This one is related to the recent 4.2 update.
[Nexus 7 Android Development] brizey:
That is kind of disappointing. Bootloaders should be simple and bulletproof. Changes in function should reside in the OS.
[Nexus 7 Android Development] sparksco:
Disappointing how so? Android has been like that forever.
[Nexus 7 Android Development] brizey:
Because it is architecturally unsound. Bootloaders should perform a very limited task set that is completely independent of the OS. My opinion of course. I just think the independence is important. Look at some of the issues people have had here upgrading.
[Nexus 7 Android Development] sparksco:
I don't make the rules for the architecture of Android, Google does. As for the issues I can't recreate any of them on my device. Some issues are bound to pop up here and there that's just part of android. Like I mentioned before, if this method fails just flash the bootloader from factory images in fastboot. Everyone that rooted their device should know fastboot. If not your just taking that much more of a risk! I don't really see why it's so hard to understand nexus devices are very hard to break unless it's just from incompetence on the user's part... I really don't understand what all the confusion is about.

[Nexus 7 Android Development] nathrinder:
Recovery still unbootable unless using 3.34

Sadly for me, I still have the same issue. Impossible to boot into recovery or even any boot.img using fastboot unless I downgrade to bootloader 3.34.

Tried to apply the 4.2 OTA on my factory restored N7 running bootloader 3.41, failed as well (which means even stock recovery can't boot, as opposed to some people mentionning issues with certain versions of CWM/TWRP)

This is really weird. Hardware issue ?
[Nexus 7 Android Development] sparksco:
Well considering the official ota's use stock recovery to update I would see that as a problem for even non-rooted users or people without a unlocked bootloader. That should be something worth complaining about as far as warranty. Have you tried locking the bootloader to apply a ota update?
[Nexus 7 Android Development] MeLViN-oNe:
Hey

just flashed the new bootloader and my device is unable to boot.

It stucks at the google logo and ends up in a bootloop.

I also installed a new rom, installed the bootloader img via fastboot but nothing.

Same problem with 3.41, only 3.34 works without problems.

Any Ideas ?
[Nexus 7 Android Development] juicejuice:
You probably flashed a bad bootloader image. Did you check the MD5 or SHA checksums on your download against those posted at the start of this thread?

Easiest fix would be to download a fresh bootloader image and flash it via fastboot.

Try the new zip it has a img in it.

I've also tried flashing 4.13 bootloader many times now from both recovery AND fastboot with the boot image downloaded directly from google and no matter what my bootloader is still at 3.34......???
[Nexus 7 Android Development] sparksco:
Kernel and ROM shouldn't have anything to do with bootloader? Probably because you flashed a ROM it clears dalvik-cache. That's why I've been asking people if they wipe cache and dalvik-cache prior to flashing.
[Nexus 7 Android Development] paranoid android85:
using the latest twrp
[Nexus 7 Android Development] sparksco:
Worked fine for me on the latest twrp...
[Nexus 7 Android Development] MeLViN-oNe:
Yeah i thought the same but after flashing the newer kernel it works.

And i always wipe cache and dalvik so i knew that wasn't the problem :P

Weird thing but i'm glad that it works now.
[Nexus 7 Android Development] sparksco:
KERNEL AND ROM HAS NOTHING TO DO WITH FLASHING A BOOTLOADER.
[Nexus 7 Android Development] sluflyer06:
So I guess nobody else's device is refusing to update the bootloader? There's really nothing else I can try, I used your file, I used the boot.img pulled out of the OTA package, I tried flashing it as different filenames through fastboot. Still at 3.34.
[Nexus 7 Android Development] MeLViN-oNe:
You're right mate but my problem was that my rom won't boot up as soon as i flashed the new bootloader.

And i think it was because of the kernel, it was not even 4.1.2 compatible, so i think is the same with the bootloader.

This maybe gave me the bootloops, the bootloader otherwise worked fine.

But please correct me if i'm wrong, it was just a guess
[Nexus 7 Android Development] brizey:
Did you flash them immediately boot into system? The version will not update until you boot "through"the bootloader. Try flashing, reboot to system, then reboot to bootloader to see if the version number updates.
[Nexus 7 Android Development] Travisdroidx2:
Funny I swear I used this already a week ago and it worked. I wiped cache using newest twrp and flashed the 4.13 zip and clear cache one more time reboot system. Let it boot up rebooted into boot loader and still had 3.41 thought maybe I hit the wrong boot loader and tried again with same results. No big deal downloaded factory images and flashed it with fastboot it works every time. Rebooted boot loader and now on 4.13

---------- Post added at 05:38 AM ---------- Previous post was at 05:34 AM ----------

Did you use the boot.img to flash in Fastboot. The boot.img is the kernel not the boot loader. The boot loader should look something like this: commands

Fastboot flash bootloader bootloader-grouper-4.13.img

Fastboot reboot-bootloader

*now you should see version 4.13

Fastboot reboot

Same story here bro, I can't move off 3.34 unless I flash the 4.2 OTA, but there's no way I'm doing that again as the new filesystem layout is a bloody nightmare if you're not planning on staying on 4.2, which I'm not.
