Hi guys, another newbie question from me
Correct me if I'm wrong, but if I flash a v2.1 SBF, then the kernel will also be flashed to v2.1 as well right?
Ok, so we also have a variety of custom roms. Some are based on v2.2 kernel, while some are for v2.1.
Now my question is, I know that CM7 is based on v2.2 kernel. Currently, I'm using a stock v2.1 SBF, so the kernel is also v2.1 as well. I want to know that despite this, can I still flash CM7 custom rom (which again is based on v2.2 kernel) on my phone? Or can I only flash a CM6 custom rom that is based on v2.1 kernel?

Are you rooted on stock 2.1? Even CM6 is on the 2.2.1 kernel, so you would have to flash the 2.2 Vulnerable Recovery and then reroot, if I'm not mistaken.

i think you can flash CM7 (if you editing rom)

your kernel will update after install the CM7, because CM7 contain the new 2.2 kernel, you can flash CM7 directly, but remember to flash the BPSW update.

Yes i'm rooted on stock 2.1. Initially, I couldn't get into OpenRecovery after flashing the stock 2.1 SBF, whereas I could when I was on stock 2.2. I did some searching and found this:
http://android.doshaska.net/rootable
and flashed the vulnerable recovery and now everything works fine. I got my phone rooted and currently using the TelusLite v5.2 for Eclair. However, i'm not sure if the vulnerable recovery is the 2.2 or not, i'm guessing it is?

Ok now i'm confused. From what I know, the bootloader for Motorola devices like the Milestone is locked. Therefore, we can't properly flash a custom rom on the phone, and we can't flash a different kernel either (which is why if you try to change one of the settings that relate to the kernel in OpenRecovery, you'll brick your phone).
So I've always thought that only flashing a stock SBF will change the kernel, and that the custom roms will rely on the stock kernel, hence why there're custom roms for different Android versions, like Eclair and Froyo? So ya i'm a little bit confused here.
Also, what's the BPSW update? What does it stand for and is that included in the CM7 custom rom topic? I couldn't find it and Google didn't find anything either.....

Oh and one more thing, I think this is a bug so can someone look into it? The statusbar hides itself and to unhide it, you have to ADWSettings (press the Menu capacitive button, in between the back and home button, and then click More, then choose ADWSettings).
Then, click on System preferences, and the first option is "Hide Statusbar".
The problem is, that option is by default already un-ticked, which means it does NOT hide your statusbar. And yet, the statusbar is hidden........the only way to fix this is to enable the option so that it actually hides it, then close everything and go back to your desktop, and then open ADWSettings again and then un-tick it. This will fix it and make the statusbar appear.
However, if you move your shortcuts/icons on the desktop around, or if you move it to the Trash, then this will undo the statusbar change and will make it hide again. So then you'll have to do this constantly, so I suggest you guys make sure your desktop shortcuts are fully configured, and then make the statusbar change at the end.

ahh I see......but I still don't understand the part about the kernel.
I thought that every new firmware version update will use a newer version of the kernel? If yes, then how can custom roms like CM7 that requires kernel for v2.2, be installed on stock v2.1? Unless both the v2.1 and v2.2 stock SBF use the same kernel version? But then again, why are there specific roms for Eclair and Froyo? If you look at this topic here:
http://forum.xda-developers.com/showthread.php?t=966812
the OP says that some of those roms might not work because of different kernels. So it leads me to believe that if you're on stock v2.1, then the kernel is different than if you're on stock v2.2, hence why the custom roms you can install are separated by Eclair and Froyo......
And lastly, if custom roms like CM7 will install the v2.2 kernel, shouldn't that require the bootloader to be unlocked?? I thought we can't change the kernel yet? I'm confused....

What you're confusing is that the version of android such as 2.2 is NOT the Kernel. The only way for you to change the kernel per se is to flash an sbf such as the Eclair or Froyo sbf. These are signed by Motorola and have holes in the code that have been exploited so we can flash Custom ROMs. The only things that we can do is flash a custom ROM or flash an SBF through RSD Lite. Kernels cannot be changed otherwise.

ya I understand that, and that's exactly the reason why i'm confused.....
If you flash a v2.1 SBF, then your Android version is v2.1 (Eclair).
If you flash a v2.2 SBF, then your Android version is v2.2 (Froyo).
Now, the problem is that custom roms like CM7 requires the kernel for Froyo. In other words, you have to flash a stock v2.2 SBF first, so that your phone will be running Froyo and that the kernel will obviously be for Froyo as well.
So what I don't understand is, I'm using Eclair right now because I flashed a New Zealand v2.1 SBF. The Android version I'm running on is Eclair, and the kernel version should be for Eclair as well.
Then why is it that you guys said I can still flash CM7, which requires the kernel for Froyo?

I have never tried flashing CM7 from Eclair, so I can't tell you that it will work. I upgraded to stock Froyo on Telus the day it came out and got frustrated with it and rooted the same day.
Sent from my Milestone using XDA Premium App
Hmm well I'd flash to stock Froyo as well, then I wouldn't have a problem installing CM7 because I know it'll definitely work. Except that the kernel for Froyo doesn't work well on my Milestone. Many people have problems with the Froyo kernel, mostly to do with connection problems like wifi or 3g.
I've had problem with my wifi where it connects to my router, but isn't sending/receiving any data. Either that, or it works for 5 mins and then disconnects itself afterwards.
Many people suggested to flash back to stock Eclair, so I did and my wifi works awesome right now and never had a connection problem yet. Currently, i'm using the TelusLite v5.2 custom rom for Eclair, and it works great but I wanna try out custom roms for Cyanogen Mod, like CM6 or CM7.
From what I know, CM6 is for Eclair because it uses the Eclair kernel. Whereas CM7 is for Froyo as it uses the Froyo kernel. However, I think the latest version of CM6 also uses the Froyo kernel, as somebody mentioned it in the CM7 topic somewhere.......so ya I'm pretty sure you CAN'T install CM7 on Eclair since the kernel requirement is different.
And yet, i'm confused with the answer in the 4th post:

I haven't heard of Eclair to CM7 directly. Every ROM except for the Eclair roms like you are running now are ALL based on Froyo. GB is based on the Froyo kernel, but is a gingerbread port.
Sent from my Milestone using XDA Premium App
yup I know. After all, there is no official Gingerbread support for Milestone (yet), that's why we don't have a v2.3 SBF to flash (therefore not able to get the kernel for Gingerbread).
But ya i'm pretty sure I got this sorted, after all the OP did specifically say that some roms might not work due to different kernels, which is mentioned in this topic here:
http://forum.xda-developers.com/showthread.php?t=966812
so ya you either have to flash the stock v2.1 SBF or v2.2 SBF in order to install specific custom roms that you want, depending on what kernel they're based on, right?
Oh well, guess i'll just stay with TelusLite v5.2 for now. It's pretty fast and stable so I guess that's good enough.

The issue is that TelusLite is no longer updated. Any issues that you will encounter may not be fixed. I've always found RSD Lite to be finicky, but you can always flash the 2.2 VR and try other ROMs and if you aren't happy, you can reflash the 2.1 and go back to TelusLite.
Many options for you to try out!

ya it seems like it. But the latest build (v5.2) was updated on July 2011 so it's only a month old? So ya not too bad. I haven't had any issues with it, and all the stuff that I use my phone for works fine on this rom so i'm pretty happy with it.
I only wanted to try out CM7 because it looks nice and that many of my friends recommended me to use it. But ur right, there're still other great roms out there that I can test out.
RSD Lite works well for me, never had a problem with it so i'm pretty happy. At least the flashing and rooting process on Android is fairly easy. Whereas on Windows Mobile or on Maemo (when I still had my Nokia N900), it was a pain in the ass, especially that the flasher program for Maemo doesn't work on Windows 7
Anyway, thanks A LOT for your help. You've helped me in the other topic I posted as well, I really appreciate you taking the time to answer my newbie questions

Well, you can open a CM7 zip package, you should see a file named "boot.img", that is the kernel, came from the stock Froyo SBF, so that it can pass the bootlooder checking, and it will replace the old kernel during the CM7 installation. That is why the kernel will update to the stock 2.2 kernel after you installed the CM7.

I see......in that case, can I replace the boot.img with the one for Eclair? I.e, use the 2.1 kernel instead of 2.2? I'm pretty sure this isn't possible since the custom rom is made to work with that particular kernel version, but maybe it does work?
Hello everyone,
I want to know how to update CM7 to latest nightlies without waiting devs to make an update to the ROM.
Im using GingerDX.
Is it just flashing the cm7 zip in CWM? Which file to download from official CM7 site.
Any idea is welcome.
http://cm-nightlies.appspot.com/?device=shakira
Install only rom, not kernel.
Use one of FXP028 FXP030 or stable CM71 kernel.
Means i download the nightly zip and flash in cwm, thats all?
Why need to flash kernal?
nAa's kernel seemed to be working fine also with CM nightly
i would like to know how too...
Can u explain? I dont want any kernal, i just want CM7 nightlies. Im using stock kernal.

How to install the rom? flash using cwm?
Custom kernels works only with unlock bootloader.
CM7 rom doesn't work on stock kernel. Only on custom kernel.
If your bootloader is unlock, the best kernel for CM7 right now is either nAa's kernel or fxp028/030 as mentioned previously.
But cam is vga only and fm radio doesn't work yet on CM rom.
If you still want to try CM rom, flash kernel i mentioned and install CM update zip in CWM.
