Kernel - Defy Q&A, Help & Troubleshooting

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?

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

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

Didn't know you can't flash a custom kernel (I have a Nexus S and you can with that one) , thank you for letting me know

Ah, that's a bit of a disappointment, but it's good to know! Thank you all for answering. However, is there really no method of unlocking the bootloader? I'd appreciate it if someone could explain exactly why that is. Sorry if this has been asked before.

The short answer in no. Zephyrot has written a good text to begin with, start reading here

Not yet is the correct answer jeje, that topic is under research in this thread http://forum.xda-developers.com/showthread.php?t=1443678
Basically, Motorola has a way to unlock the bootloader, using the OMAP tools and a key owned by Motorola, is possible to unlock but no one can find a way to do that without the key...

X-play custom rom

Hi I'm new to the custom rom's and instead of searching through countless topics, mixing up instructions. I was wondering if I could get some directions.
Play is unrooted 2.3.3. I would like instructions on how to put a custom rom on the phone, and which custom rom would be recommended. Thanks in advance people.

is your phone fastboot enabled? (does the notification light in the power button turn blue if you hold the search button and then connect the usb to computer?)
If you want a custom rom but dont want to search and read these forums, i give your phone a week before you brick it.

or we could help people within the comunity to understand what's out there, the risks involved and how to get around the problems that could arise? we all need things explaining to us once in a while.
Oh im sorry i see your point, it is always good to be helpful, i am trying to be helpful as well when i say you should search and read, i mean look at all the countless threads where people didnt want to read, theres like 3 help im bricked threads per page.
lol. i know what you mean. and i know it can be frustrating. it's just a shame that the play is so much more complicated than the x10 that i was previously on. it was all flashtool and update.zip stuff. practically unbrickable!! loved it. fastboot and adb complicate things, and i feel that some of the tutorials can be a little confusing to total noobs. so we need to be accomodating to their lack of knowledge (i hardly know anything, so i'm still quite noobish), but also, people need to accept their own actions and consequences. not sure what i'm getting at now, but things need to be simpler for people who want to start out
Actually the way of installation is exactly the same for any custom ROM in this phone.
1) unlock your bootloader, either for free if you bought a factory unlocked phone or for some cash sending Alejandrissimo a PM, which you have to use if your phone is branded and/or Sim locked. You only need to do this step once.
2) install a custom kernel. There are two: DoomLord's kernel and the Cyanogen Mod kernel. The latter allows you only to install CM7. Doom's allows you to install the others.
3) Enter in Clockwork Mod recovery and install the ROM you prefer as long as your kernel of choice supports it.
As to which ROM you should pick, I use CM7 because it's stable and fast. Visit those threads and see for yourself which is the one you like best.
my personal favorite (until cm7 became more usable, and also because i like dooms kernel) was zerojay's aptly named zerorom. it's a very clean and fast sony based rom full of optimizations and tweaks. i'm currently trying out the FXP028 release of cm7 to see if it's more to my liking than it was in previous releases.
Unfortunately locked to Rogers. Is there a free way of unlocking the bootloader and how?
Again I'm currently running 2.3.3 nonrooted. Had it rooted on 2. 3. 2. but ofcourse lost it with update.

True, but paying $20 dollars to get it unlocked sounds like less of a pain in the ass

Bump, has anyone been able to get Cyanogen mod onto the Rogers r800a? This locked boot loader is really causing me grief. Have the phone rooted, cwr is installed as well as busy Box. Getting closer, but still no cigar.

You can flash CM7, but i doubt it will boot with stock kernel.

You won't brick it, if kernel is incompatible device with either not boot, or bootloop, flahing stock rom with flashtool will fix it though.

is ther any ICS roms for verizon R800x

hey my play comes in the 3erd and i will like to know is there any working ICS roms for it and how to go about doing every thing i need to. i use to have the lg ally running velocity v1.2 but by the looks of it with my new play i have flashing roms and recover look way harder then the ally was so i need some info guys and a guide and what roms are save to flash and what recovery do i need to have also and thanks for you help also!!!
I havent seen any ICS roms for the r800x but recovering/flashing roms is made very very easy with this from the android market "Xperia CWM Auto-Instaler"
You don't even need to unlock the bootloader, just needs to be rooted and then go about setting up the Xperia CWM Auto-Instaler and just make a nandroid backup. I would reccommend using Cola's rom or IT-ROM (which is based off of Cola's rom) for the r800x, they both have worked perfectly for me and I'm currently running IT-ROM which definitely makes the r800x run much smoother/faster.
Wifi, 3g, sms, ect all worked without any issues, and if you're somone who is worried about being able to overclock, I know someone is working on that with Cola's rom, but I dont think it's finished yet. But, those roms take care of basically any speed issues one may have with their r800x, it definitely did the trick for me.
Good luck

Read more prior to posting... There's a lot of info in here (no ICS), and unless you take the time to sift through it all and understand it, you will mess up your phone.

ya i know that as i have done all of this with the ally but what i dont know is with this http://forum.xda-developers.com/showpost.php?p=14815942&postcount=4 do i root and then flash the recover and then install the rom because i know the recovery does not work with stock and thats what i will be on or do i install the rom and then the recovery if i have more info on this then im good
How are planning on installing the ROM without recovery? Seriously, read everything again so you don't brick your phone.
And make sure you're installing a ROM for locked bootloaders.... If you try to install that CM7 ROM it'll likely never boot again.

ok i looked up some info and i can not unlock my bootloader on the R800x i am so happy i did not try and flash the CM7 lol
you can unlock your boot loader it just cost $$ , someone with setool , a paper clip and not minding voiding your warrantee. I would not suggest it until you've gotten a bit experience under your belt but when you get there its worth having done in my opinion , many people vary on this subject and they're right also.
There is limited real benefit to unlocking the R800x, since the devs have been focusing on the locked ROMs... Not much out there, unless you're planning to develop it yourself.

Indeed, fully functional cm7 is hardly worth unlocking your bootloader for

[POLL] PrimeHD on Stock Kernel?

I've opened this thread because I want to collect some statistics. Please participate in the poll.
Please click on 'Yes' only if you haven't unlocked your bootloader.
I have some targets for this i.e. the poll will only be counted only if it has 100+ participants, otherwise ignored.
Thank You.
No, dude it is outdated. We need to upgrade our kernel for better performance. But this will be helpful for those who can't open their bootloaders so yeah useful for some people.
YES !!!!!!!!!!!!! My frenz need it cause his hardware is 11w51, criticaly dangerous to unlock.
Yes. Not unlocked bootloader 11w33

I need the ROM for Stock kernel. I don't have any problem updating with Kernel but with boot loader.
101% yes!!!Because i dont want to unlock again my bootloader because now i know the risk...
i don't use stock kernel but i voted yes for stock kernel, because here have much people that can not unlock bootloader, then people, vote yes please for stock kernel because these people thus can use this rom in their phones..FREEDOM OF CHOICE!!
sorry my bad english

yes plss
I tried to unlock my bootloader once and it just end with a hardbrick and it takes 1month for the se service center to repair my unit
reason
Reason is simple. I had a simlock. For now there is no safe way to unlock bootloader and the simlock NOT to come back.
Cheers,
yea i want it on stock kernel i have unlocked my bootloader but i want it for those who cant its the best rom ever and i want it for my other brothers as well
I want more ROMs on stock kernel.
11w48 I bought my x8 almost 2 months ago and the first thing I tried was to update it. Then I realised that my phone will never get past 2.1 ,so I read that I can manually install 2.2 or 2.3 ROM. And a week later my phone was running gingerdx. But I wanted something more, I wanted a custom kernel and I was very disappointed to read that I can't unlock my bootloader. I check the development section about 10 times a day and Im very happy when I see a new ROM or a ROM that gets updated. But most of them are for alfs or nAa and I feel like noone cares about the people who can't unlock their bootloaders. I voted YES. Thank you.
I guess the development of this rom will released till xmas if we wait the 100voters because not all is participate...
As of now 42 have voted with 31 for and 11 against. Guys please don't vote against there are lot of your brothers who can't unlock their bootloader..please please vote infavour.
Sent from my X8 using XDA App
YES please
Well as said before, many of us cant unlock bootloader and there are few roms to pick from that are updated for us. I would really like to try this ROM. And would like to see other ROMs updated as well. We all want the same thing. A smooth, good looking rom that is up to date with the best modules, speed mods, and completely works. I have found a couple. but most you gotta enable, and update modules. Some dont even have any modules, so you got to use root explorer to install them yourself. Thank You for asking this question. Hopefully it will get more attention to itself and other roms that wed like to see on stock kernel. Oh and a bunch of yes votes.
Yes we need more Rom's for stock kernel as I don't want to unlock bootloader. My x8 11w01 so should be fine to unlock. I hope for ics on stock kernel but this is not looking promising.

Bootloader

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?

[Q] What is 2ndboot?

Hi,
I currently have CM9 on my Defy+.
I saw that there is an update to CM10 with/out 2ndboot.
Could someone please explain what 2ndboot is and whether I should worry about it.
I only intend to use my Defy+ as an average user.
Thanks,
neiljain
Seek and thou shall find 2nd boot for more info.
And no, you shouldn't worry about it.
Well you don't have to worry, since we've got a locked boot loader any issue can be solved with a simple reflash of your stock sbf. As for what the second boot is read the link on the above comment and what it does, in what could be a layman explanation is boots a secondary kernel for to enhance the custom ROM experience (I guess )
