Bootloader - Defy Q&A, Help & Troubleshooting

If the bootloader is locked to only accept signed kernels would it be possible to forge the signature? I have never thought about the development before so sorry if this seems stupid.

Why not man great great idea.
Provided you have one of the nsa's super computer..
Sorry for being saccastic but the moto key is 1024 bits thats gonna take ample amount of power to break it.(days ,months or maybe years.)

One more stupid idea from me:
We have some guys who have unlocked bootloaders , those who got the defy repaired from service stations and now have a SE OMAP. Can those guys compile a kernel which suits our need and we can just flash the kernel like we go a CM7 or CM9 (froyo or GB) from recovery?
Its just a thought.... If we just need kernel, why not go this route?

check project cheesecake in development subforum .it would help you as am noob when it comes to bootloader and development.
Btw lets see i have send my defy for a motherboard replacement and see if i get a unlocked bootloader or not..

even if they can compile a kernel, we would not be able to flash it on locked one.

Ohhh. so thats the sole reason we just have two kernels of defy...
one is froyo
other is GB
Both locked to bootloaders.
Thanks for the info...

Thanks, could we make a custom sbf and use that as a base for cm9?

Someone Make a CM7 Rom Please.

I love the cm7 and wish someone would make a cm7 rom for the D2.
Its pretty much impossible with the locked bootloader. Cm7 needs a custom kernel that the locked bootloader doesn't allow, so were stuck with stock.

well that sucks.
Try liberty, it's about as good as it gets at the moment. I think keyjar is also working on a gummyJar GB version, which should be a solid rom as well. There is a working UD port for D2, but it's still on RC2 and hasn't been updated in a while, though I ran it for a few weeks and it was pretty solid. Liberty GB is also in the works, though not publicly available atm. CM7 isn't really necessary for the D2, since most of what you would get can be had in other roms currently available, just via some different means.
any way to get the lockscreen gestures currently?
Cm7 DOES NOT need a custom rom. It will run better if it does but it's not required. But we don't have aosp Rome such as cm7 because the locked bootloader makes it hard to make things work

Alright I wanna clear this up.
Cyanogenmod is a custom rom. We can install those on our Droid 2/X devices with Koush's Bootstrap tool. That said, we cannot install a custom kernel. Thus, cm-kernel for Droid 2/X is probably not going to happen anytime soon. However, that is not to say that Cyanogenmod 7 requires a specific kernel. I see no reason why Cyanogenmod 7 could not run on the stock Motorola kernel.
Moving on, cvpcs is working on a Cyanogenmod port for Droid X (and thus also Droid 2). When the rom will be stable, however, is unclear. As far as I understand, it's not really working.

More importantly, this is the development section, not the request section. There is no request section for a good reason.

Ok, for those who aren't searching these days...
1 - Cyanogen won't come out officially with a D2 port until Moto unlocks the bootloader
2 - Cyanogen actually doesn't need a custom kernel to do what it does
2a - Go use Liberty..its effectively Cyanogen sans a 'custom kernel' and does all the same.
Me, I'm flashing back to stock for a while. Liberty 2.0 is causing me some headaches as of late and I can't download @#$ from the market it seems cause its like everything is fricken blocked now.

I thought Motorola stated that they would unlock the bootloader, but it was up to the carriers whether or not they would allow for it.
Jordan umts is the codename of the Defy... which is also locked.... and we are the 4th device in cyanogen 7 number of installs stats

Originally, yes, it was Motorola's policy to lock the bootloader, but they had announced recently that they would leave the bootloader unlocked, at least for phones on carriers that allowed it (so, I would at least guess that AT&T would be out of the picture, since they've even been controlling of the ability to sideload apps).
Working on it come help if you can:

hello again my friends
i have moto filpout from a week ago
it very good phone
now i collect this inf about the phone
it has arm processor can be overclocked to 1 ghz
gpu as galaxy s that is the surprise & i can make it preform higher than galaxy s
the bad thing is screen resolution is 320x240
i see that there arent any devolper work in devolping its rom
so i suggest we devolp it with our selves just try to help us and all share us
i am now have froyo2.2 package as update.zip & as RSD flashable img
THE PROPLEM IS IN BOOTLOADER .... IF WE BYBASS THE VERSION WE CAN FLASH IT
ANY SUGGESTION?
Rsd can be flashed easily as per debranding guide.
where did u find 2.2 ?
Sent from my MB511 using XDA App
NO IT DOESNT as boot loader stop the system to boot and start i know about debrand and i extract file sys from moto flipside it has 2.2 froyo update and have same hardware of moto flip out but screen resolution is 340x320 i sucess in flashing but it say critical error
the proplem is in boot loader and file named sw in depranded sbf
i notice that filp side have bootloader 91.1b
but our devices have 91.10
any suggestion if we solve this we can make froyo very easy i think the proplem of screen resolution not affect on android booting
-----------attention i didnt flash the boot loader of flip side i just take system only
i think if i flash bootloader the phone will be dead

other files?
Is it possible to extract all the files from the rom, and overwrite what we have directly, then we'd have 2.2 except for the boot process/kernel...
Something similar was done for the milestone, I think.

i am now success in flash a kernel which have low energy & high performance & get full access to system file read & write but when i replace the files with froyo 2.2 the phone is still on moto logo small thing is missed i try to port if any devolper help us i would be greatfull
Man, if you can make Froyo happen on the FlipOut, that'd be awesome. I'm definitely buying one, if it supports Froyo They're becoming quite cheap, here in Italy
OT: how much cheap? My boss has one and I was thinking about making a FroYo/GingerBread ROM for it, but I don't want to fry his phone in the process
BTW, tech info hour: Motorola has released (a looong time ago) a set of files needed to compile Android for the FlipOut (and many other phones). This is the homepage.
The very first step should be to compile Eclair and give it a try on a real device. I don't know if MotoBlur is present (I hope it isn't...), but if the ROM works, the next step is to switch to the FroYo branch, compile again, fix what's broken, test on a real device, move to Gingerbread and so on. FroYo and GingerBread have differencies in the USB-SD handling, so it's highly likely that some changes to the kernel will be required. I don't know much about changes between Eclair and FroYo which affected kernel stuff.

Gingerbread for Flipout?? That'd be nice. BTW the Flipout would be nice OCd too, it's processor can handle it (it's not a low powered phone, really)

Yes, a looong time ago. But they are useless, because you can't flash them. The bootloader is locked, and motorola won't release the key.

I think I saw a modified Clockwork Recovery for the FLIPOUT, with a comment that it could not mount the filesystems, but it could flash update.zip files. ATM I can't find it, though.

bootloader and kernels

Okay now this is a guide for maybe noobs and mostly software modifiers.​Hi reader. thanks for reading lol. now this piece of work is something that even educates me. welcome to wilbso's unlocking bootloader and adding kernels guide. im gonna try and keep this short so you dont nod off...
What is a bootloader​Well...a locked bootloaer (normal) is something that stops you from adding custom kernels. you think that rooting your phone and loading a custom rom is all. well you thought wrong. yes you can install drivers such as multitouch etc by rooting but unlocking your bootloader is a totally (almost) different thing. now, these days, gingerdx requires linuxdx-which requires unlocking your bootloader. unlocking the bootloader can either end up in satisfactory... or... full and complete brick. now a full brick is-blah blah blah ( i will make a seperate thread for what type of bricks there are and what they mean)
so, basically unlocking your bootloader properly free's your phone. still think your up to it? wow your pretty brave lol...
What is a custom kernel?​A custom kernel is something other than a stock kernel.need anymore?
It is something that improves your phone. make it stand out. it can also improve the performance of your phone. if you would like to see a guide on how to build a custom kernel then click here
how to unlock your bootloader.​ I have unlocked my bootloader and I followed these threads. It would be a good idea to follow this and this
but when i did it i downloaded flashtool, s1tool (to check if my bootloader was unlocked) and something else ( i cant remember what it was called but it ran in my terminal i think). when i did unlock my bootloader i checked it with s1tool (i cant remember if THATS right either though lol) and i successfully managed it ut i still recommend reading the links that i put.
please, do hit the thanks button on my posts and the posts i put links to. i would greatly appreciate it.
kernels​i have looked at many different kernels since august ( the month i joined xda) and they all look cool.
flash them by a flashtool. i now run linuxdx v04
here's some kernels i have come across:
A gingerbread kernel
Linuxdx v04
Alfs for gingerdx
If you have any questions plese post them here or my FAQ or my latest guide to roms and mods. Also i am not responsible for any damage to you phone
And remember to press the thanks THANKSbutton
NO trolling here is tolerated either. cheers!

i dont know much about miui cuz i isnt supported for x8 but if your talking about bootanimation. a boot animation is something that replaces your current boot up logo. you can get an app that does it and you can flash them with a recovery i think

You don't have to flash kernel if you don't want to.you can unlock bootloader by itself. Just unlocking it means you have the ability to flash kernels and drivers

[Q] Kernel Question

Hey guys,
Its been a while since ive messed with my defy. Im looking to change my rom, but all this kernel talk has got me a bit confused. Here is my current setup.
My Defy Currently:
Android: 2.3.4
Rom: MS2Ginger2.0
Kernel: 2.6.32.9-g15cc991 [email protected] #1
All im trying to do is put another rom at my phone. Currently, im thinking of trying MIUI. Anyways, ive been reading that they only support froyo or certain gb kernels (usually below 2.3.6 i believe).
At the moment, im looking at installing MIUI pickachu edition. Can I just boot into CWM (2ndint), and run the zip of my SD?
Any input is appreciated. Thansk
Absolutely! I've been flashing all kinds of stuff onto my defy and have had no problems at all, any rumours you have heard or read are just that... RUMOURS! Just go ahead and flash the rom, chances are it'll work, and if it doesn't you should have a backup of your previous one anyway!

Im just a bit reluctant to flash alot because I remember bricking my defy every other day when it was first released. It would take hours to try get it back running (my pc is really old and slow). ive been putting up with MS2ginger2.0 for a while, but the sluggishness and the random reboots have been getting to me.
I guess ill try it when I get home.
ah, i feel for ya man. but I'm afraid its the only way you can fix this.

?? How can you say that... You didn't take the time to ask him if he's a Defy (green or red lens) owner, because I'm sure he isn't a Defy+ one and you told him : don't worry there is no problem of compatibility, all you heard or read is only remours !!!...
So, if he brick his phone hope you'll donate to him to replace his old computer to be able to flash a new SBF... But for sure I'll not donate to you...
I can say that because through extensive testing that in total wasted a week of my life, I KNOW that any defy can have that Tom. Plus, its almost impossible to brick an android phone... so please stop trolling when in fact, there is nothing wrong with what I said
If you flash a bld 7 rom on a green lense defy, you can't use your camera anymore. It is also wise to not flash a rom from witch you can't downgrade from. My defy for instants had the bug where your in-call speaker dies. If I had flashed a wrong rom they would have noticed it as it returned with another sbf than I had send it with. So if they got an error flashing this, I wouldn't have got my warranty.
Just saying.

You are right, it's almost impossible to hard brick a Defy. But, because of its locked bootloader it's very easy to have a soft brick or be blocked on a version without possibility to downgrade. So, i'm not trolling but you cannot affirm that these kinds of problem are only "RUMOURS".

Hey sutitan,
Well, I would tell you to flash froyo full sbf first, but I haven't tried MIUI myself so i don't know.
But I was myself a veteran of MS2Ginger 2.1 and 3.0 when I tried to return to CM7 on a 4.5.1-109 kernel and, well, it didn't work. (4.5.1-109 is a 2.3.4 kernel)
I would suggest that you play it safe and flash froyo fixed or froyo full and then proceed from there.

...and as for you, sir, I have been through 4 soft bricks, and have been testing ever since I got my defy. I am not going to list all the roms I have used as proof.

Kernel

Hi guys,
I need some help, sorry I'm a noob with defy... I'm trying to find a good kernel to flash but I was not able to find any.. I'm looking for both performance an battery life wise..
Can you recommend me a kernel and if possible get me a link of the thread please?
Sent from my MB525 using xda premium
You can't just flashh a kernel, first you must use a rom which works with that kernel, if you wanna a good batt life flash CM72, has a great batt life and works great
Sent from my MB525 using XDA
Are you sure? I have a Vibrant and I think it's quite possible to use a stock rom with a kernel of your choice on it. I'm new to the Defy as well, so I would like to know why it's different for this phone. I tried searching for an answer, but I can't seem to find any posts or articles specifically relating to the Defy and kernels. Pretty much everything just involves roms.
that's because the bootloader of defy is locked .. ;( ... Samsung has unlocked one you can put any compatible kernel in it .. but in defy .. only either FROYO one or GINGERBREAD one is the option :|
On Defy we have just two kernels, the GB and Froyo Kernel both signed by Motorola, we can't use custom kernels cause a locked BL, the GB is from the Defy+ Stock Rom, and the Froyo from Defy Stock, i never tried really the GB kernel over the Defy stock, maybe can work, but it will not give you a big difference in performance or batt, cause the Motoblur, first of all, root the phone, install 2nd init and then you can flash the GB kernel aka CM9 kernel here in the forum, but i suggest you to flash CM7.2
