I have a rooted r800x phone with 2.3.3 running on it right now. The phone is cdma. I installed cwm on it via the xperia app from marketplace (locked bootloader still). My question is where csn i find compatible cfw for my phone and how do i go about installing it? also if there is anything else i need to know please feel free to mention. This is my first attempt at cfw on a phone. I really want to overclock the phone so any help is appreciated!
All firmware files can be found in the Dev section along with instructions (note the ones with CDMA in the titles).

Unfortunately with a locked bootloader you limit yourself to only stock based ROMs, and it also rules out overclocking. The reason being is that for other firmwares (CM7, CM9, MIUI, etc) you need to flash a custom kernel (the kernels also what allows you to overclock along with some other low level tweaks) and you can't do that without unlocking your bootloader.
*EDIT* And since people keep telling you you need to flash a kernel to do anything, here's the first step:
http://forum.xda-developers.com/showthread.php?t=1322827
Read that, that's how you unlock your bootloader (it costs $24ish last I checked), you can't overclock without it, sorry, that's how it is, it's the only way. After that you still need to flash a kernel with fastboot, which is a process in itself. So read up, there be good information in these here threads.

Hey
I just got a brand new Defy and I'm hoping I can get ICS on it. However, in my country there's no T-Mobile, Verizon, Orange or whatever, I bought it in an electronics store, so I have absolutely no idea about what CG version it is. I've already read the beginner's guide from top to bottom, but I still have some doubts:
1. How do I know which CG version do I have? (I need to know so I can know how to get back to stock in case of warranty)
Nevermind, I found the answer >_> CG 4 SBF 3.4.2 (Froyo)
2. I've seen lots of ROMs for this device, but their instructions aren't very clear and I don't want to brick my device (which, from what I've read it is very hard to do) or get stuck in a higher CG version.
3. The beginner's guide is cool, but I haven't seen any tutorials on installing a specific rom (in my case ICS) so, I'd appreciate some pointers here, if possible
Thanks in advance! =)

I have a defy+, so i have 2.3.6 on it. But you don't need to flash any new firmware to get ICS or MIUI, since they both have froyo builds. CG version only changes when you flash full SBF, not when installing zips and custom ROMs. So you shouldn't worry about getting stuck on a higher CG.
So what you need of course is a rooted phone , the SndInitDefy_2.0.apk (to install custom recovery and bootmenu because of locked bootloader), install the latest bootmenu (don't mind installing the old one although it might work on froyo). And there you're ready to flash! (to enter custom recovery on your defy, reboot your phone and press the volume down key when you see the blue led) I assume you know how to use the custom recovery, so I won't go into detail on that.
Since I haven't flashed any froyo ICS builds before, I don't dare to tell you how to myself! So just head over to the main CM9 ICS thread You'll find a guide in the first post. Nevermind, i'll just quote it here:

How to flash ICS (Defy Builds)
1:Head Over To Stable recovery
2:Wipe Data
3:Install Zip from SD Card
4:Select ICS(Defy) .zip
5:Flash
6:Flash CM7 Kernel
7:Clear Cache and Dalvik Cache
First Boot will take some time...

You need to flash Google Apps seperately through recovery. You should find the files and links needed in the thread linked above. Know the difference between the Defy+ builds (with gingerbread [gb] kernel), and the Defy builds with froyo kernel.
Please note that ICS for defy is still in it's early stages and you might experience bugs. But most people still think it's worth it! xD Sorry if I made it too detailed for you, but then others can make use of it too! Oh, I hope I haven't said wrong that will soft brick your phone! Flashing the wrong kernel always gives me bootloader error! Anyway bricking really isn't that scary (only the first time i can confirm) It's good to have an SBF with RSDLite and Drivers installed on your PC just in case
Oh! And then If you want MIUI, just do the normal wipes and flash the ROM. Let me recommend MIUI Pikachu edition by TweetyPeety, the best MIUI ROM out there! It even has the touch based AROMA installer in recovery where you can customize the installation!
I was wandering if there is any advantage in flashing a newer kernel (either CM9 kernel or a GB full SBF) on defy if I'm using CM7/CM9/MIUI
Also, I tried CM9 without flashing the kernel, and it works, so I can't figure what difference would that step make. How does changing the default kernel affect the use of custom roms? Any hit in performance/usability? Would I have to use Defy+ roms if I flash CM9 kernel?

I think you shouldn't flash new kernel for CM9 since it is in alpha
it is better to keep on CM7.1 and wait until a stable version from CM9 (unless you are a real HW or SW developer)
Hi all, first of all i want to mention that i have researched and read everything i can about Defy unlocking and still have some questions which bother me because the Defy+ comes with ginger as def OS.
I want to get a Defy+ (which is carrier locked and i don't know the exact operator it is from) that should run on a modified CM7.2 or maybe some other ROM at time as 2init. Most of the tutorials are for Defy(non +) and CM 7.1/Froyo.
The questions that bother me are:
1. Will the method for softunlocking work on Defy+
2. Will it work on any other CM BASED ROM like 7.2 official/MIUI/Pikachu/etc, and must i have a certain SBF(full)
3. Is the soft unlocking method bound to certain radio version and will it work in Europe?
Here are the links i find the most simple:

I know the tutorials are relatively clear but it means allot to get confirmation from people that have done this as i can buy the defy onlu once .
Thx in advance.

1. Yes, the method for rooting, and installing 2nd init is the same in the Defy+, the 2nd init 2.0 works fine on Defy+.
2. The only important thing when flashing a ROM is over which kernels is the ROM based, for the Defy+ you must use the GB kernel version of the ROMs, you can't use a kernel with a lower BL version than the one your SBF has.
3. Each ROM has a Baseband switcher where you can set the Radio frecuency.
Any doubt, just ask.
Ok ,thx for the info.
One more question, will the soft unlock work on ANY CM7.2(GB based) ROM? And will it work on CM9/10 later on?(If u know)
Found the info thx for the reply, everything is ready now .
hello sir me not succes in unlock my defy plus till....
plz help me wht i do for it...

Hi All,
I've done literally weeks of research on this, so hopefully I've not missed any easy posts, but I want to check my approach and ask a final question. This is my daily phone, and while I know the risks and issues with custom roms, I want to get it right. Hope someone can advise.
ROM I want to install is Quarx's JB 4.1.2 CM10.
Phone I have is UK Motorola Defy (Red Lens, original):
System version: Blur_Version_2.21.0.MB525.Retail.en.GB
Model Number: MB525
Firmware version: 2.1-update1
Baseband version: EPU93ST2_U_03.02.00
Kernel version: 2.6.29 [email protected] #1
My plan is:
1. Official upgrade to Froyo - it seems this is not yet done on mine, and custom ROMs require its Kernel, I read
2. Root phone - SuperOneClick
3. Titanium Backup - Needs Root
4. ClockWorkMod Recovery - Needs Root, and gives me Nandroid Backup capability in BootLoader
5. Nandroid Backup - this should provide me a route back to stock (* see question below)
6. Flash ROM - this will give me CM10 based on Jelly Bean 4.2.1
Question is, despite reading many threads, I'm still confused on CG versions and SMG file versions (CG##.smg). I do want to be able to flash back to stock after this, in case I want to sell the phone - if I flash up to Quarx's CM10 JB 4.1.2, what CG version is it and is it higher than I can possibly get back to stock from? Or can I find a Fixed SBF of a Stock ROM that will let me go back? How can I best prepare for this?
Anything else to be aware of or concerned about?
Thanks very much.
Steve.
The easiest approach is to directly flash cm10 first and check off it works(you can flash back your stock sbf if there's any problem) because CM10 WILL NOT INCREASE YOUR CG VERSION
The potential problem you can face(which can not stop you from stock sbf flash) is an incompatibility of 2ndboot with your stock kernel.
If you run into that problem (which I think should not occur) you will have to flash a compatible sbf, with higher cg version and a compatible stock kernel.

Thanks - good to know CM10 has no CG version. I expected the developers to want to get rid of that kind of limitation as soon as they could!
Hmmm, so could someone confirm, that Quarx's CM10 will flash directly over the stock 2.1 Eclair ROM as listed above (with root/CWM), and doesn't need Froyo deployed as a base? That would really help if so - then I have no further considerations and I can just get on with it. I'll take it carefully and I'd rather not be faced with non-booting etc the first time round.
I believe wifi tethering doesn't work on it, though, or there's some problem with restarting regarding wifi tether. That's a shame, but maybe an app like Barnacle or OpenGarden can work instead...?
You could try it yourself by taking a Nandroid backup and if you face the non booting problem then flash stock sbf+ restore. Beware that sometimes first boot hangs or bootloops and in such cases you can fix the problem with a battery pull, or data wipe respectively
Open garden works without issues
Hit thanks!
Hi, I have a rooted verizon galaxy s7 (g930v) and i flashed some rom from here that a user uploaded that gives me the s8 icons and some other fancy stuff without too much affecting stock.
I read about getting a different kernel would allow the cpu frequencies and such to be more in your control, and I was wondering how i can go about getting a custom kernel.
The only problem here is, Almost every tut i've seen requires TWRP, and the last time i tried to install it, when i went into recovery booting, i would get in a bootloop, and i last heard it wasnt supported for the s7 anyway.
So I guess my question is, can someone link me a compatible version of twrp (if there even is any for the US variant on verizon), tell me how to install it, and please let me know with a link to a custom kernel that should work on my verizon galaxy s7?, with instructions on how to get it in my system? (I've read everywhere sorry for being a noob with kernels.)
I really wanna work on this and it's been driving me nuts! I would really appreciate any and all help i can get on this matter.
Thank you.

The bootloader on the Verizon S7 is locked. I believe with a locked bootloader you cannot load TWRP or a custom kernel. You are basically stuck with variations of the stock Verizon ROM with the stock kernel.

Damn, well in that case could you answer me this: I want to improve the performance of my phone without losing battery, I know tweaking the cpu and things of that sort could help, but in your personal opinion what would be the best way of controlling such things and their values? I've tried LSpeed, didn't really help, I used kernel adiutor, but one thing i noticed is that i think my system has its own cpu managing techniques, because if i went into kernel adiutor, set the min to 307, when i move my finger it shoots up to 900 then back down, in other people's videos of kernel adiutor i don't see that, any idea on what that's about?
I assume it's something in my system that's making my cpu do that, and i think that's why im not getting the snappy performance I crave. Any ideas?
Appreciate the help btw

Without a custom kernel, you can't tweak the CPU. Can't have a custom kernel on the S7 because of the locked bootloader. So there you go. I haven't tried messing with anything to improve the performance of my S7, so sorry I'm no help to you there.
hello,
i'm looking for a ROM, that everything works. Everywhere I read, this or that doesn't work.
I'm looking for something that isn't too old and everything works without a problem.
it is not necessary to have android 9 or 10.
Thank you in advance for your answers.
Someone?
I can't guarantee that every single thing will work but blackdiamond n8 is a fantastic rom. You can choose which bloatware apps you want and other settings

Then stay on stock rom its the best one that fits your criteria..
Also depends what you exactly need custom rom for.. you need often to sacrifice on somethings to get another ..
At this point.. if you are new to rooting and custom OS scenario, i recommend staying on stock.. because it is now more complex procedure and gives far more problems sometimes then it gives benefit. Imho the benefits of rooting/custom OSes are degrading slowly to the point where its just a useless hassle..
But ofcourse its everyone's choice.. you want to live on the edge by trying new OSes/new things/features you are free to do.. just make sure you know how to do everything safely, and backing up the vital data, like copying your nv data (the first thing after gaining su access), knowing the correct/safe procedure and please DON'T "ACCIDENTALLY" turn oem unlock off..
I personally recommend gaining su access by SYSYEM LESS methods plus magisk in order to avoid dm verity errors and encryption problems.. it also makes it less likely to mess with your nv data..
See alexndr's system less dev base and custom rom.. its based on stock 8.0 too (i think its all stock) and also stable too
https://forum.xda-developers.com/s7-edge/development/rom-dqd1-devbase-v4-1-multi-csc-safe-t3591647/
OR if you want to live on the edge.. backup your nv data and try custom roms like black diamonds, hyper rom, deluxe rom and any other which is being actively updated/supported.. try and find your taste on your own and report problems on their threads (every rom has their problems)
But i would either root stock "system lessly" or flash alexndr's custom systemless OS devbase
