Can I install CM7 on 2.1 kernel? - Motorola Droid and Milestone Q&A, Help & Troublesh

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.

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.

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?

OCLF uses ext2, which is less safe than ext4, which is used by Voodoo. If you want Voodoo, flash the JJ4 + Voodoo kernel in the dev section.

Depends. The newer Kernals really unlock a lot of features that we didn't have before, and you don't have now.
If you use your phone as your media player, than the benefits of Voodoo sound were enough to make me switch.

Hey folks, another Canadian Rogers Captivate user here...just wanted to confirm if I can use the Voodoo stable 5.4.1 for Froyo 2.2.1 as it looks like I'm on 2.2 stock (and rooted)? I'm new to android and a bit scared, but the Voodoo fix seems easy enough..
No one seems to be answering the main question posed here.
For us STOCK Rogers froyo users which version of voodoo should we use?
I am not running a custom rom, I have not used Odin (used Kies to install official froyo update). I can't seem to find a version of voodoo lagfix specifically for stock Rogers 2.2. If anyone e has it installed can you point us in the right direction?

People have been using the SpeedMod kernel which is the Rolls Royce of kernels; it enables a lot of the Captivates features and power. However, the Kernel is based on the i9000 kernel, which is the sister handset to the Captivate. The kernels are compatible across both phones, but the stock modems on captivates don't seem to do as well with some setups; you'll see this in the sprawling thread dedicated to that topic. Some people will flash an i9000 modem as well, and people seem to have varying results with different combinations.
Having said that, if you don't want to use bluetooth, the stock modem is perfectly serviceable. You could go ahead and flash your SpeedMod kernel and see vast improvements is phone function without tweaking in the handset's general recovery menu. There's also plenty there to keep the tweaksters busy
However, new to the scene is the same developers amalgam of his voodoo lagfix in a stock Rogers Froyo kernel. I'm running it now and I am still testing and checking things, but it seems fine though. There are some caveats to respect though, I just spent nearly an entire day getting my phone back to Stock Froyo after doing a bad job of 'un'lagfixing before flashing kernels. However, if it's your first endeavour into flashing or modifying your phone's software, it would be a relatively safe bet. You should not have any lagfix installed nor should you even think about doing it without doing a Titanium Backup of your phone, which would mean rooting.
Hope that helps a bit.

It's sort of officially unofficial. It would seem to be a prebuild for a forthcoming Gingerbread release, it's tight and a great daily driver.
I did use Odin; follow the usual safety procedures and all will be well. The modem that comes with the package is great, but my 4G no longer works, it's 3G for now, but I got terrible 4G speeds anyway, so there's not much of a downgrade there.
The GPS did not function so great straight away, but I keyed in the code *#3214789650# - Settings - SUPL Settings, and changed the server to supl.google.com and the server port to 7276. I got much better results from that configuration.
Hope that helps!
Thanks for the help of gps friend ... I have it installed and this great .. But you have some voovoo installed, can not find any on the net .. The voodoo 5.5.x served me just to change the start GTI9000, I do not like .. Thanks for your help..

[Q] confusion about JVB/JVH and other only letter listings

im very confused about the captivates organization of roms and what is and is not jvb and jvh.. i own a fascinate. and the only (only letter) acronym used with the fascinate are our "MTD" roms which is the file system used for our aosp roms..
what roms are jvb, jvh? what is your most current source? gingerbread or froyo? what is your most current ota?
JVB, JVH etc are leaked builds for international galaxy S I9000 which have been ported to work with captivate. If you go by this JVR which is 2.3.4 is latest.
But all these are I9000 sources modded to work on captivate. If you are looking at stock captivate build it is KF1 which is GB 2.3.3. KF1 is also a leaked build
Ok.. I have decided to go straight to miui. On the fascinate I would just odin all in 1 stock. Odin a recovery. Flash rom with kernel. It seems like all the guides I find want me to root.. Why would I root if I'm leaving the rom behind end going straight to a rooted rom? .. Is there a guide to flashing miui for captivate I'm not seeing? On fassinate you must flash cm7 first. I'm thinking I would do the same here right?

In answer to your question, here is the guide.
You'll want to be rooted for one simple reason - usually rooting allows you to install the ClockworkMod Recovery Menu (CWM) that will make installing Roms on the Captivate a whole lot easier.
Judging from the guide, you don't need to flash CM7 first. Just make sure you're running the original Froyo/Eclair bootloaders (if you haven't flashed gingerbread, you should have them), and that holding Vol+/Vol-/Power gets you to the recovery menu and that holding Vol+/Vol- and inserting your USB cable gets you to download mode.
Other than that, MIUI away.
Is your version of miui a mtd based rom?

I honestly couldn't tell you. I haven't used MIUI, so I don't have any experience to say. The MIUI info page is a little sparse, but a quick search in the thread does mention MTD a few times, so it's possible.
Cappy miui is MTD based. Gingerbread bootloaders do work but the stock miui/cm7 kernel doesnt ssupport them yet so you'll need to flash a kernel that does support the gb bootloaders such as TalonMTD

I ran miui on gb loaders with no problem. And I used the platypus/NEO 10, 12, & 16 kernels. Talonmtd actually kept causing my phone to freeze up.

But could you access your external sd card on GB bootloaders?

[Q] Can I "downgrade" from 2.3.4 to 2.2?

At first I tried Fasty II but the GPS was worse than what I was used to (KB2 stock ROM). I'm currently using the Fusion V ROM GB 2.3.4 but the GPS on it stinks as well.
Anyways, I've heard good things about the GPS on Fasty v2.5 KB1 ROM and since it is similar to KB2 I thought I would give it a try.
So, my question is: Can I flash this ROM while on GB bootloaders?
I seem to remember reading somewhere that the GB bootloader was backwards compatible. But I want to verify before flashing Fasty v2.5.
Thanks!
Shawn
you should be just dandy

Well I just tried to flash the ROM, but it said that it wasn't supported. I guess I need to flash back with the one click stock KB1. I'll try that next.
Thanks!
That's because the froyo ROM is written with ammend scripting.for cwm 2.5 and below and your most likely running 3.0+ which uses edify scripting.
Flash a froyo kernel with Odin/heimdall or sgs kernel flasher and then flash the ROM.

Thanks for the info, but I already flashed back to 2.2 1-click. Now I guess I should be able to flash a KB2 ROM. Assuming I figure out how to install CM that works with the stock 2.2. I'm back to the 3e version.
Shawn
Just do now what studacris said before... that is, just Odin/Heimdall/SGS kernel Flasher a Froyo kernel with CWM already baked in and then u can flash the Froyo Rom of ur choice.

Look for Speedmod-Kernel-K12u-t4-500kz .. flash it on your 2.2 with Odin and you'll get CWM for 2.2 that will let you flash 2.5. I always use this method when flashing new roms. Works great for me. I used 2.5.. it worked great on GPS.. Mosaic VII GPS also works great for me too.

[Q] New on android and I had problems with kernel talondev

Hi all,
I'm new to android and some things I do not understand, for example I have the galaxy captivate with the following characteristic:
Rom Android 2.3.4 I897UCKH3
boog_kh3_kernel3
su-2.3.2-efgh-bin-signed.zip
I updated my cellphone using these files, and all works fine but I wanted install a new kernel the last talondev, but after install it I think that my sgs is on soft bricked, displays the logo of AT & T and then starts "loading talon...", but then restarts.
This kernel can be used with the rom? it is compatible? or What should I do to choose a kernel?
Best regards
Talon is I9000 port kernel you are using native I897 rom. Use Samurai, Corn kernel or Boog's kernel. Actually Im not sure there is a corn or samurai kernel for KH3. I know they have it for KJ roms.
I have to find kernels for KH3, right?
Thanks
Correct. Or update to a newer leak like KJ3 as a example.
And I can change to a custom rom? or that such the cm7 rom?
I talk to do this to exit the soft brick and have it back.
thanks
CM7 has its own special instructions. I haven't kept up with it so go to their thread and read. But ya you can change to custom roms like Fusion IX, Fasty and others that are based of a newer firmware version.

You need to flash back to boog kernel. If this does not work it is best you re-flash to stock KH3 with the one-click solution here. http://forum.xda-developers.com/showthread.php?t=1300843
Choose the one WITHOUT bootloaders since you already have those on the phone. It is safer that way.
Regarding CM7 ROMs. You must know they are completely different system compared to the normal Captivate ROMs. Read this thread before flashing:
http://forum.xda-developers.com/showthread.php?t=978150
Don't get me wrong. THEY ARE VERY GOOD CUSTOM ROMs...absolutely. But you cannot mix and match.....Follow CM7 instructions strictly.
thanks for the replies, I will be reading information about their opinions.
thank you very much , I'll let you know the results.

Why would you send him to the nightly page and not the 7.1 stable current nightlys are a bit broken.
I am not amused by your phones performance

I would guess you are on GB bootloaders, but it doesn't matter which ones you are on if you're going to CM7. I wouldn't worry about it until you flash to something else. At that point you can either just reflash a full package with bootloaders to be sure or try flashing without them and see what happens. You should get a pixelated screen at boot on GB if your bootloaders are Froyo.

Yes, as long as you flashed a GB bootloader to get on GB then that's what you have. Just go ahead and flash CM7
Sent from my (CM9) ICS i897 Captivate
As mentioned earlier, if you want to know, just flash a gb ROM. You'll know if you have the wrong bootloaders as soon as it boots. If you think you may have the I9000 bootloaders, power the phone off and try volume up and power at the same time.
I read some where that froyo bootloader is neccessary for flashing cm7. So if I have ginger bootloader. Will it make problem? ?

Not anymore. It used to be froyo only, but now it works with either. However I9000 GB bootloaders may not play nice.
Ohhhh that's nice to know. So it means I can flash cm7 even if I have gb bootloader? ??
Well, yeah.
Whats the difference between cm7 and cm7 nightly ?
For all practical purposes, nothing. CM7 is compiled nightly (well, sort of, the build bot is currently broken) with updates, new features, bug fixes, etc. Every so often when they get a version stable enough for everyone's liking, they make it an official build. The reason I say there's not really any difference is that the current nightlies are at least as stable if not more stable than the current official release.
181 was the last official nightly released if I remember correctly, but you can find other people who are compiling the updates themselves. The one many of us are using can be found here: http://forum.xda-developers.com/showthread.php?t=1347273
thanks for reply guys

Just download the nightly to your sd card and install it from recovery. And no clue, I have never had any lag with adw launcher. You can try others to see if it helps

Cm7 is going to have worse battery life than touch wiz roms. Its a known issue with aosp roms. They don't contain the closed source hardware drivers. That the tw roms have.
