[Q] Why Flash Bootloader and Radio? How? - Paranoid Android Q&A

In the changelog for 4.4 RC 1, we are told that we need to flash a new bootloader and radio. This has not been part of my normal process. Why do we need to do this? Also, I wasn't able to find any threads on suggested bootloaders and radios for PA. Please point me in the right direction if this is something I really need to do. (using a Nexus 5)

4.4 RC1 - Kitkat 4.4.3
Dose of awesome sauce on this week from PA Headquarters, again. As you may know we merged 4.4.3 into our source. You will need to flash new bootloader, radio, Gapps and update to latest recovery before going forward. Many bugs have been also resolved on our bug tracker thanks to community’s reports, less to go.

Flash stock 4.4.3 and then flash PA. Did the same for my primary N4
Sent from my Xperia S using Tapatalk

I ended up unzipping the stock package and selectively flashing the stock Bootloader and Radio.
I'm not sure why I needed to do this, but I did it and I'm using 4.4 RC 1 now.
Thanks!

It was mentioned to do so but should have specified that it was only for those old 3.99 holdouts that weren't ready to switch. Mainly only applied to mako users.

Yes. You do not need to update anything but the rom

I'm kind of in the same situation, except a Nexus 7 2013 LTE is my device in question. I've been searching everywhere and haven't found any answers.

You don't need to update anything then. If your device didn't come with any new boot loaders or radios then there is obviously nothing to update.

[Q] How to upgrade to Android 4.0.3

Hi,
Just got my Nexus. Can't update it as Nexus says it's up to date. And my Android version is 4.0.1 at the moment.
But I see in your signatures most of you have 4.0.3.
Do I need to be a developer (must have SDK or smth) to upgrade? Or is there a simple way to do that?
Thanks!
4.0.3 OTA is not available. It's in AOSP.
Only way to get 4.0.3 is to use a custom ROM .

That was quick
I think I will wait for official. Have no balls messing with custom ROMs at the moment Tired already of messing with Windows Mobile and searching for a perfect ROM (didn't find that in 3 years).

well luckily for you if you ever decide to go the custom rom route, the people at samsung, google, and the wonderful developers online have made it almost idiot proof, and safe to do. you will probably be surprised how easy it is. in fact, most people seem to have the most issues installing the windows(or mac) drivers properly.
peter alfonso - peteralfonso.com has the Bugless Beast rom, which is nearly stock aosp, and very stable
i have to say I tried rooting, unlock and custom rom... and the hardest bit was finding the right drivers.. but used the universal ones (in the forums) and it worked like a charm.. Just follow a guide and it's simple... but I've stuck with stock as the camera functionality isn't as good in AOSP... will flash cm9 when its ready though
go with the one touch app for rooting and the touch clockwork app they work great

You don't need to install any drivers on Mac to make fastboot working. Just download a fastboot binary (like on Linux).
Btw
When we should expect 4.0.3 to be released officially?
How long it usually takes to release a new version?

no ETA. it is ready when it is ready.
flash to custom 4.0.3 if you want it now
I am also still at 4.0.1 and when I check for update, still no 4.0.2
When were will be an update to 4,0,3 will we be able to update without losing all the settings?
I have Backup checkbox marked in my settings.
So, if I'm on 4.0.2 and download a 4.0.3 ROM it will be compatible? Same with flashing a 4.0.3 kernel on a 4.0.2?
Thanks

Well by the sounds of it your not planing to root your device (at least straight away). Although if you do decide to purchase I recommend it as there are numerous fixes with custom roms/kernels. The battery out of the box was shockingly bad but this was quickly fixed by flashing a new kernel and it improved dramatically!! The other issue out of the box I had was the signal dropped out every so often but you can flash the latest baseband and that resolved the issue.
Hope that helps...

and for the signal drop issue which baseband should i flash?btw...is baseband different in every country?? i'm a noob
It depends on the rom you might flash. Some like CyanogenMod have a modified kernel that improves performance and battery life anyway. I personally like Francos kernel but it some what depends on your experiences with different rom/kernel combinations and experimentation.
As for flashing the 'right' baseband, there are different releases depending on your location. However this is not to say that a asian baseband won't work in europe (they do). So again this calls for personal experimentation and seeing what works best for you in your area.

i'm from malaysia(asia) so which baseband do u think i should flash??
again...i'm a noob...i really appreciate tat u answer my question...thanks alot...
The version out of the box will more than likely be 4.0.1. If your planning to root anyway then you don't need to worry about what you get out of the box.
If your bootloader is locked (which it probably will be) when you get your device you will need to unlock this. Doing so will wipe your device so it's recommended to do so sooner rather than later.
EDIT:
After this point flashing a new kernel will not wipe your app data (unless you want to )
There are 'stock' rooted roms available, I but I believe these are limited to 4.0.1/2 only. If you want great performance I would recommend a custom rom.
The Toolkit (here!) is a great tool if your new to the whole rooting scene so I recommended looking at that.
You can have a look at the list of basebands as well (here!) which might make the situation a little clearer. There's no 'easy' answer, as I said before you need to do some reading and self testing. Everyones situation is different depending on exact location and rom combination. Don't be afraid at trying these new things (you can always flash a different one).

now to think of it...maybe i'm not gonna root my phone...cuz it void my warranty and galaxy nexus cost a looooooooooooot in my country...it's really expensive...
i'm sorry but what is bootloader?
thx again for your help...i'm doing some research about all this procedure right now...
As far as I know (I may be wrong), unlocking the bootloader and rooting the device does not void Samsungs warranty. Even if it does you can relock the bootloader/unroot your device so there were no signs of you tampering with your device in that manner.
Try aokp with Franco kernel.
The best rom I ever use in galaxy nexus.

No. The newest official version is 4.0.2.
In the development section of this forum there are 4.0.3 roms available because they are in aosp but 4.0.3 never never got pushed ota. There are leaked 4.0.4 roms too.
To flash a kernel you need to unlock your bootloader, flash clockwork mod recovery and flash from there. Don't flash Franco.kernel over 4.0.2
Just use the gnex toolkit to do everything, its simple.
Then read about bootloaders, adb and fastboot.
very valuable knowledge.

It will update to 4.0.2 from 4.0.1 when you turn it on and it will upgrade Over The Air (OTA)
Aosp is android open source project.
All the code for android is free for people to take and build and is stored in Google's aosp repositories.
Read as much as you can, nexus are quite simple so you'll figure it out.

For a nexus, flashing a custom kernel requires root or unlock bootloader?
What is the use of unlock bootloader on a nexus device?
I came from a sony phone and that require unlocking bootloader to install custom kernel..not so sure about nexus.

Well you need to unlock your bootloader in order to root. I think you do need to unlock. But unlocking the bootloader is super easy so I don't see a reason not to.

BE CAREFUL of updates. Newer updates change the touchscreen driver!
If the touchscreen is working perfectly out of the box, DON'T UPDATE OTA.
If it works out of the box, I would recommend not updating and/or just flashing an updated custom rom without the touchscreen updates.

Thanks for clearing that up for me, fellas.

Is there an "official" 4.4.2 zip for Nexus 7 2013 Flo?

Hello xda developers!
So I had a quick question that I am really hoping that someone here can help me out with...
I have my N7 2013 32GB WiFi only model FLO tablet running Android 4.4 rooted (of course) with Multirom installed.
Okay so when I rooted my N7 I flashed the kexec kernel patch so I could install Ubuntu Touch...not knowing that Ubuntu Touch is only available for the N7 2012 tablet. So a few days after installing the kexec-patch an upgrade was available for Nexus 7. I tried installing the 4.4.2 upgrade but I knew that it was not going to work....
What I am wondering is, is there a way I can download the official ROM for the Nexus 7 (I want the official) and flash it with TWRP and Multirom? Will Multirom allow you to flash to the "internal" ROM?
If I can flash an offical nexus 7 flo rom I can then just root it again with the Nexus Root Toolkit.
I have done a lot of work with other ROMs on my Nexus 7 tablet that I have installed with MultiRom and I really don't want to have to erase everything just to put the official 4.4.2 upgrade on my N7. Yet...I really want the upgrade because I have heard they fixed a lot of issues with the camera.
Has anyone uploaded an apk for the official Nexus 7 4.4.2 camera app? If I can't flash an "official" nexus 7 flo ROM could I just install the camera apk from the Nexus 7 4.4.2 update?
I am really hoping someone can point me in the right direction here...
On a personal note I just want to say how much I enjoy this place and I am so thankful for xda and all the amazing work contributed by the developers and testers. Thank you all so much!
You all are the reason I will never buy an iPad or iPhone!
I thank you all for your time and your assistance.

You can download factory images here. https://developers.google.com/android/nexus/images#razor
The included flash-all.bat will also restore the stock recovery, but you can always flash TWRP afterward. Someone else will have to chime in about MultiROM, which I've never used.
Pandae thanks so much for the reply...
I will check the link out further when I get home.
I am really looking for something like an official OTA zip that I can flash where I can keep my other installed ROMs with twrp and Multirom.
If anyone has done anything like that please let me know...
Thanks again,

stock kernel for 4.4?
I am thinking now that maybe if i can get a hold of the stock kernel for the Nexus 7 on Android 4.4 i could re-flash the stock kernel to remove the kexec-patch and then i could apply the official OTA update to 4.4.2
Does anyone think this would work?
Does anyone happen to know where I might be able to get the stock kernel for the Nexus 7 FLO for Android 4.4?
Thank you all so much for your time...

I haven't seen a flashable zip for the stock 4.4 kernel. If you have adb setup you can extract the boot image from inside the factory image and fastboot flash that. Did you make a backup (nandroid) after you rooted? Of course you did! Just restore "Boot" from your backup made with TWRP. To get the OTA to work your "system" will also need to be stock and you need to have stock recovery. If you don't have stock recovery and you have TWRP for instance you can flash the OTA zip with TWRP. At the very least your system and kernel will have to be stock to get an OTA to work. Edit: I just saw this ROM Stock Rooted 4.4.2 - KOT49H and it looks like you have to flash the bootloader seperatley. Flash the ROM and bootloader with TWRP.

Okay so when I rooted my N7 I flashed the kexec kernel patch so I could install Ubuntu Touch...not knowing that Ubuntu Touch is only available for the N7 2012 tablet. So a few days after installing the kexec-patch an upgrade was available for Nexus 7. I tried installing the 4.4.2 upgrade but I knew that it was not going to work....
What I am wondering is, is there a way I can download the official ROM for the Nexus 7 (I want the official) and flash it with TWRP and Multirom? Will Multirom allow you to flash to the "internal" ROM?
If I can flash an offical nexus 7 flo rom I can then just root it again with the Nexus Root Toolkit.
I have done a lot of work with other ROMs on my Nexus 7 tablet that I have installed with MultiRom and I really don't want to have to erase everything just to put the official 4.4.2 upgrade on my N7. Yet...I really want the upgrade because I have heard they fixed a lot of issues with the camera.
Has anyone uploaded an apk for the official Nexus 7 4.4.2 camera app? If I can't flash an "official" nexus 7 flo ROM could I just install the camera apk from the Nexus 7 4.4.2 update?
I am really hoping someone can point me in the right direction here...
On a personal note I just want to say how much I enjoy this place and I am so thankful for xda and all the amazing work contributed by the developers and testers. Thank you all so much!
You all are the reason I will never buy an iPad or iPhone!
I thank you all for your time and your assistance.

Hello, There is a way to download the stock ROM. I will leave a link and a tutorial on how to install it below. If you just want to flash it with TWRP then copy the .zip to your flash drive or whatever. I prefer to use fastboot because then I can flash only certain parts of the update and preserve my root. Hope this helps.

Hey DroidShadow,
If none of these worked for you, i have newer and better ROMs that ive come across over the past three months. Let me know if u want a list of them.

Kitkat OTA

I have an m on jb rooted with safe strap is it possible to let it take the OTA to kitkat then root with tr and unlock the bootloader? If it can update will it give me the version that can't be unlocked? If I can't do the OTA how else can I get it on the right version of kitkat?
This has everything you need... Use rsd lite to upgrade to kk make sure you upgrade to 182/183.46.10 so you can unlock the boot loader
We cannot teach people anything; we can only help them discover it within themselves.
Do you have a link to a download of the kk software? I'm at work looking at this on a phone don't see a link in that thread to it

Read through the thread linked to above and make sure you understand. There have been many people getting stuck at .15 and we don't want you to be one of them!
Firmware for use with RSD Lite: http://sbf.droid-developers.org/phone.php?device=8 . Note that unlike OTAs, flashing with RSD Lite will make you lose your data and your internal storage contents - back up first. Use the 183.46.10 one, and if you want to unlock your BL, DO NOT TAKE THE OTA TO 183.46.15! I SAY IT AGAIN, DO NOT UPDATE TO 183.46.15!!

So flash this file using RSD Lite afterwards phone will be on the version of KK that can be rooted with TR and bootloader unlocked with motopocalypse. Then can install custom recovery. I thank you for your help
As AndyYan stated read through the linked thread, it has very well written instructions complete with screenshots and links to the required files and please be sure to thank ATTACK for his time in putting it together for us... Just go to the original post for the walkthroughs and hit that thanks button to show him some well deserved appreciation...

Just reread if I understand it correctly I don't need kk just the firmware. . . If I'm understanding it correctly

Huh? The firmware's version is KitKat. You need the full firmware to be on KitKat and unlock your bootloader.
Bonus info: after upgrading to KitKat and unlocking, if you find KitKat's battery performance isn't satisfactory, you can always downgrade back to Jelly Bean using the guide in General section, and because this will not relock your bootloader, you're safe to do this.
If you have any trouble doing the above, read through the guide and other forum posts, and if no answer comes up, feel free to ask.

I wrote that the wrong way. What I mean is the firmware file listed is a 750mb file. For my m8 the 4.4.4 firmware update was only 24mb. This leads me to believe that this file includes a kk rom to go along with the firmware. Read a little more(light bulb went on) I thought firmware and roms were always two separate things. . . Duh now I understand why just the one file is needed. I will give this a shot when I get up. Thanks for the help again. Sorry I was asking the wrong question ☺
Thanks andyyan and dbreezy187 all worked out got it done eventually ☺
That would be

Ha, he hasn't unlocked his BL yet, so just let him upgrade and do it. After unlocking BL he can still downgrade to JB and maybe even flash CM11 for JB BL (and that's what I recommend).

Thanks again for your help. Now that I'm all unlocked I've seen a lot of stuff about jb and kk bl. I would assume I have a kk bl? Then if I downgrade to jb would have a jb bootloader. Do you have a favorite kk rom and a favorite jb rom? Is downgrading any more difficult than doing all the unlocking? This phone isn't my daily driver just kinda having fun with it ☺ sorry for the barrage of questions you seem waaayyyy more knowledgeable than I. Thanks again

The BL version is the same as your *stock* OS version, so because you now have stock KitKat, you're on KK BL. However, BL version is *not* tied to your custom ROM OS version. You can have KitKat with JB BL as well.
Please do note that some custom ROMs are built for a specific BL (e.g. CM11 has JB BL and KK BL variants).
As for now, it seems that most if not all ROMs for KK BL have minor but annoying issues, particularly in WiFi, BT and GPS, so if you want to avoid these issues, you can follow the guide in General section to downgrade to *stock* JB (in order to have JB BL - this will not relock your BL), then flash any JB BL ROM you want.
I'm always a CM fan so I load most of my devices with CM (see my signature), but if your RAZR is also a secondary device, you can try all the choices out there without worries, so why not?

Thanks for the info. I'm still very new to all this the only phone I've really messed with is my m8 it's just roms and firmware. People like you make it a joy to learn and figure this stuff out. Thanks again

One last question I forgot. Can you use adb with this phone or only mfastboot I ask cause that program seems to hate me ?

Didn't know if you had seen this but seems like an easy way to go back and forth between roms and bl's http://www.droidrzr.com/index.php/topic/50096-how-tomobile-downgrader-flash-back-10-09-14-14/ seems almost to good to be true. What do you think?

Hmm, what do you intend to do? If it's flashing something in the AP Fastboot mode (e.g. boot logos, raw partition images) then no ADB. Custom recoveries and the OS itself accepts ADB commands pretty well, provided that you know how to use.

Looks good. Since you have a unlocked BL, there's near zero risk for trying anything (RSD's your best friend when everything fails) - go ahead if you feel adventurous.
Since I don't know what boot logost and raw partitions are don't think I'll need it. I know enough about adb to be dangerous ☺ I can usually bumble fk my way through and get it to work. Thanks again I'll give some of this stuff a shot and have you on speed dial if I really mess up
