Bootloader download? - Nexus 6 Q&A, Help & Troubleshooting

I was trying to update to 5.1 the other day and I got the newer radio but the only download link I found for the bootloader just 404's. Could anyone help me out with a download link for the bootloader that can either be flashed in fastboot or in recovery?

Why update the bootloader at all? Its not a requirement.

I had a lot of issues on the 5.1 ROM where the radio would be crashing every few seconds and was never stable. Using a 5.1 radio, 5.1 ROM, and 5.1 kernel. Figured it needed the bootloader to work right or something. The 5.1 radio is actually running perfect on the 5.0 ROM I am on once again until I could solve the issue, so I know it isnt the radio itself that is causing the crashing.

The problem is once you upgrade it, you can never downgrade it again. And then you're stuck with the danger of relocking the bootloader on the new version.
I imagine most of us who rooted when we first got our device still have the original bootloader (I have) so I would say it's not that.
Usually there is no reason to update the bootloader. I know sometimes CM "force" that, but it's very rare that there is an actual need for operational reasons..
Also FYI, Once the bootloader has handed off to the kernel during the initial boot process, it has no further interaction with the device (until next boot) so any issue in the rom is very hard to tie to the bootloader whilst its dormant.

Ok thanks for the info, guess I wont update it then. Ill try and debug the problem some more then and see if I can nail it down

If you exhaust all.options and feel you have no way forward, the best place to get the BL is from the official factory Image. Bigger download I know....

Radio update help..

...It's pretty much been over half a year since I needed to root my phone again, but I just received a brand new one from tmob.
SO. I did the root deal, that went super smooth, I have JF1.51 CRB43 ADP to start with.
NOW, I am trying to update the radio, and it does not seem to be working. From what I remember and what I've read, all you do is flash it like you would any rom, rename to update.zip and recov alt+s, right? Well, when I check the radio version it still says the original, not what I flashed. So I re-downloaded and tried again, no luck.
....feel like a real idiot here haha, never had it not work before. Tried searching but I had no luck finding the solution. By all means if you have a link and this was a pointless post just tell me, else I just need some help!
which recovery image do you have installed

If your using Cyanogen's recovery, try to physically press the alt-s, and home + back to reboot
I believe it works like that for flashing the IPL (radio) and SPL
where did you get the radio from?
Sorry I left out the recov info, I know my signature is misleading...didn't change it yet..!
I'm using JF 1.43 recov, I remember that (not sure if it was ever fixed, all I know is that flashing the SPL with CM recov caused 'error at line ___' when flashing new roms) that you cannot flash the new SPL with cyanogen recovery, so I'm using JF's until I get the radio and spl flashed correctly.
I got the radio from where I usually have in the past, as well as the new SPL
http://sapphire-port-dream.googlecode.com/files/
(Of course I will not flash the latest SPL until the newest radio is flashed first!)
I just want my happy CM 3.9.7 back..! With the ability to flash the new hero roms when I get curious..
****I am now attempting to flash the radio with cm recov 1.4, will update on this if it works.
****no luck with cm either, didn't think it would make a difference but thought I would give it a shot. I still have 1.22.12.29 for my radio :/ agh!
So...Still can't update the radio for whatever reason, just does not take, and I still can't find anything in the forums about this either... :/ Anyone have any ideas at all?
get the radio from the htc website maybe you got a bad download. i have flashed radio and new spl with cyanogens recovery so i know it will do it. after flashing the radio press home and back to reboot. do not reboot from the recovery console because i have noticed that it will not write the image.

Thanks for the link ^-^ I will give it a shot. Good to her that the CM recov flashes the new SPL alright now..! I will post results...every time I flash it goes through the motions of writing the radio but just never shows that I have the new one..super frustrating.
** I also notice that whenever I have tried to flash the radio on the new phone, when I reboot it goes through the appropriate motions, yes, however it puts me back into recovery every time. I wonder if I should just completely start over (unroot, re-root) hope thats not the case..I just got it all set back up again :/
Nope, no matter where I download from and how many times I flash with different recoveries.. I still have the original radio 1.22.12.29 :/
This has always been so easy! I've never had issues with rooting, then updating the radio, then updating to the new SPL.. :/

If you can, try rerooting, it will only be a few more steps.

Yeah, I was hoping to not have to but I will in a bit here if I still can't figure it out. I have root just fine, running CM 3.9.9.1 even, which I usually only run his roms, however I do like to try the Hero roms as well as they come out..
bummer :/

I don't know why its not updating your radio, but everything else works fine. You should update the radio before updating to cupcake builds. maybe that will help?
gave up for a while, finally re-rooted
Re-rooted and still cannot update my radio, I have tried updating it after the very first rooting steps, after updating to JF RC33 as well, I still can't get the latest radio to get onto my phone. I have tried with JF recovery, CM recovery, as well as the original recovery image, and nothing. Notta. Zip. No idea why my phone simply will not take the new radio image.. I have re-downloaded it a million times as well, going in circles..don't get why the phone will let me root, unroot, all that jazz, and simply will not let me update the radio... driving me nuts!! I can use CM roms just fine of course but any other roms I am stuck with not trying cause of this annoyance!! Anything anyone can recommend would be great
o man still can't get it to work?
try flashing the official 1.5 OTA update, which contains the updated radio. see if it gives you an error message. if it does, take it to tmobile and tell them to replace your phone.
if it flashes...see if it updated your radio. if it did, you can use the one click root to root your phone
Thanks again buddy, I will try it out ^^
So, I unrooted, and applied the OTA updates from 29 to 30, 30 to 33, 33 to cupcake..and I still don't have the latest radio, still at 1.22.12.29. I got the ota cupcake here:
https://android.clients.google.com/updates/partner/signed-kila-ota-150275.53dde318.zip
i'm going to try flashing the ota radio update without root if it will let me..grr..this is so weird, there is no reason why it shouldn't take a simple radio update..hrm
***attempted the ota radio update, guess you can't without root which is what I figured, but frick, this makes no sense.. >>
so, this is a bit odd, at http://developer.htc.com/adp.html, one of the spots to DL the latest radio, when you hover over the radio link for 1.5 and 1.6, it says "ota-radio-1_22_14_11.zip" rather than "ota-radio-2_22_19_26I.zip", weird, eh? Wonder if it's simply not the right radio, and labeled wrong, I have no idea, but this is getting super old.
I'm actually having the same problem, can't seem to update the radio with the radio image the htc site provides. It's still stuck at 1.22.12.29
Anyone had this before? Any help would be appreciated
I can't get around it, and it's really frustrating, since the only rom I can use is a CM build..aside from a couple others, but CM is the best as far as universal SPL use goes..
So what I've tried so far:
- Updated to HardSPL
- Tried multiple Radio updates, new ones, old ones, even some from the forums.
- Tried a few complete updates that include the radio image
- Tried flashing directly from fastboot, not sure what partition I need to flash though, the radio partition gives me an error that it does not exist.
Still no go. The weird thing is that I come from a stock 1.5 installation updated from 1.0 via t-mobile. And I'm still at the original 1.0 radio image.

Downgrading radio version 5.08

Hy there ! I have a question about downgrading the radio from version 5.08 to 4.06. It is possible to do it without bricking the system?

I'm pretty sure you just have to flash the older radio in recovery. You can only brick the phone if you take out the battery while it's doing it, or if your battery is too low (so make sure you're at least 50% or 100% if you're really paranoid).
Any verification on this? I have the 5.08 radio and it's not as good as the older one, at least, for me.
edit: Nevermind, I decided to give it a go and it seems to have worked.
Thanks.
Just today, after about a month of 5.08, i downgraded to 4.06. Just flash it, simple and let it do its thing. Took a couple minutes to boot back in and it felt like the phone was stuck on the nexus boot but it pulled through.
Main reason for downgrading was that 5.08 was a little unstable. Noticed crash after crash when it lost reception.
4.06 is slow though
My problem with the 5.08 is that i loose 3g signal all the time. Maybe the 4.06 works well i have to try it

[Q] How to go back to stock rom with a unlocked, 30.BC bootloader

Here is the problem.
I updated my xt1058 to 5.0.1 , so my bootloader was updated to the 30.BC version. It still is unlocked and I've TWRP installed too working good. After the update, a few days later using the stock rom, my phone got stuck on a bootloop, even after I wiped everything using TWRP the bootloop continued. In order to continue using the phone I installled the official CM12.1 rom over the stock, did all the wipes and then I could boot and use the phone.
My problem is that CM12.1 isn't fully functional yet, and I get random reboots, signal loss, and some apps crashes the phone and I really wish to come back to stock rom since I miss some stock features. There is a way to do this or I have to wait for a 5.0.1 SBF appear? And there is really no way to go back to stock 4.4.4 because the bootloader update right?
Thanks in advance for the help!
There may be ways that some will suggest using part from one rom, and parts from another... HOWEVER while that might give you what appears to be a "working phone" you may find some features not working, or some bugs that weren't there before because you have mismatched "parts" on your phone. And you will be at great risk for bricking your phone should you take an OTA in the future.
And yes, there is no 100% safe, and "will never brick" way to downgrade, even with an unlocked bootloader. It is why I spent the time writing this -> http://forum.xda-developers.com/moto-x/general/info-warning-risks-downgrading-impacts-t3058202 (which includes a collection of links to threads where people did brick trying to downgrade)
At this point, if you don't want to risk bricking your phone, and want to SAFELY get back to a Stock Motorola ROM, you need to wait until we see a leak of the Stock Moto SBF that is the same or newer build than the last update you flashed on your phone. It will bring all parts/pieces of your phone back into line.
So I'll have to wait the SBF, hope it doesn't take too long!
Thanks for the help.

It takes as long as it takes...
You wont see a 5.1 SBF util sometime after 5.1 starts pushing to ALL PHONES on all carriers, Moto has posted the Developer Images on their web site anywhere from a few weeks to a few months after the OTA update has been pushed. For all other carriers, since MOTO doesn't post/publish them, we are at the mercy of someone on the inside grabbing them and leaking them, so there is no telling how long that might take, and if it will definitely happen.

Where do I get the latest baseband, radio, kernal?

This is probably a newb question. I've rooted and flashed many roms but never really messed with the kernal. I have 7.1.1 Pure Nexus and I think I have the same baseband as I did on 6.0. Or maybe it's in the ROM? I googled a bit but if someone can point me in the right direction then I can download and flash.
***Dork Alert, ok I just noticed the big "[Kernal]" in the description. Now I need to read and see which one is good with Pure Nexus
You can download latest factory image from here, and extract it you will get bootloader and radio images and you may flash via fastboot

Thank you so much, you guys are great. I'll do it asap. I think I posted in the wrong forum also, so I really appreciate the help. This is probably also a dumb question. I just update the radio to the latest 7.0 one. Do I need a updated bootloader?

For nougat you should update bootloader, radio update if you like to see which one runs best for you
So far it's super responsive and smooth. With 7.1.1 is got better and now more so so I'll do bootloader now.
Take a look at http://forum.xda-developers.com/showthread.php?p=59728002/

Thanks again, I did do the radio and bootloader and so smooth and battery seems better than before. I can go all day again =). I was thinking of getting another phone but now it's perfectly fine

OTA Beta Updates

Hi,
One of my friends told me not to do OTAs beta updates because it could bootloop my phone.
Last update I flashed the zip and all worked perfectly fine, but I had to re-root my phone and re-uninstall annoying stock apps with titanium backup.
Now I have a question :
Is it really risked to do the update with an OTA download ?
I really don't want to re-root my phone and do all the other stuff that comes with it.
I guess there is a way to do a safe update which keeps my data with the OTA but I need a confirmation about that.
Thanks !
(Original post [here] but probably faster answers on this forum, I guess ?)
I think it is ok with official updates. I have not any issue. Just i have not rooted or etc. All stock

Thanks, but I would like to have the advice of somebody with approximatively the same setup as mine, I mean at least with a rooted op3t
If you have all stock, then I can't tell if doing the OTA update will re-stock my phone too
I always have stock phones, because early time when i tried root, unlock btl, install twrp, change rom... sometimes there were wrong things, examle booting only logo and phone make a stone looks like, also custom roms has some bugs and on stock i am sure that everything works good. I do not understan why people starting root, change roms or etc. Use stock always and everything will be ok

U better off using an iPhone
To answer OP, yes you can struck in bootloop.
Remember it's beta version and not stable release.
