Flashing difference between Samsung and HTC?

Hi all, i'm currently with a HTC Desire and the procedure to flash a new ROM was first to flash a moded bootloader and a recovery from which you could just flash any .zip ROMs...
I'm not familiar with samsung, but I see that there is a tool called ODIN which you use to flash.
Can someone explain the difference? Will we always need a PC to flash a ROM or will be there a possibility to have a moded bootloader + recovery?
odin is to flash the .tar roms , mostly stock roms . In Galaxy s series if you have a hacked recovery like cwm 2/3 you can flash .zip roms also .
Diffrence 1%
We are doing the same but flashing the kernel + recovery with ODIN and then everything is the same
Also we are flashing ROM's with recovery, there is no need of PC, just to download the ROM's.
I'm not sure but, the bootloader is unlocked so, do we need to flash modded bootloader !?
Strange to me.

That makes sense!
Мерси, колега.
this is a question, should have been in the general section.... wrong thread. pls read the rules before posting buddy.... & try to keep this forum as clean as possible....
there is not even a single element of development in this new thread.... user has a doubt regarding different ways flashing of ROMs between different brands.....
pls dont repeat the same mistake.... search the forum carefully first, then you post in an appropriate section if you dont find anything what you are looking for....

Question about installing new rom

Hello all. I decided to install Hybrom on my Xperia mini pro (sk17i) but i'm little confused at the moment and don't know what to do. I have installed CM 7.2.0 rom with FreeXperia kernel. If i want to install the Hybrom, i just need to flash stock firmware via flashtool, install Clockwork once again, then install some custom kernel like Rage and then install the rom? Or do something else? And do i need to relock the bootloader to flash stock firmware?
Install stock firmware, install kernel, install ROM. That's all. No relock needed. Custom kernel already includes Recovery so it is not needed.

And when i flash firmware, wipe is automatically done so i don't need to do it manually?

Flashing stock firmware - if you choose it in Flashtool, then yes.
Custom - no, you have to do it yourself before installing the ROM.

Thank you, I really appreciate your answer, but I have one last question. Does the firmware already include rom and kernel, or rom only? And do I have to install newer baseband to it to make the custom rom work?

Stock firmwares in .ftf file already include ROM and kernel both.
Most custom ROMs have their own custom kernel that you need to install yourself. Sometimes it is written in the topic as separate download link, sometimes it is included inside the .zip file, then you need to extract it and flash via fastboot. Check my tutorial, if you need help with it.
Baseband will depend on the custom ROM.

Hi and welcome to X10 XDA first of all There are few steps you got to get through for safer flashing.
1)Update to OFFICIAL 2.3.3Gingerbread using latest SEUS/PC Companion by Sony to get Baseband 2.1.71 and Stock SEMC Kernel
2)Get Flashtool [newest or Older version] to Root your X10
3)INstalling Xrecovery [Optional but got benefits if you installed it]
4)[MUST]Using S1Tool, Check your SIMLOCK CERTIFICATE whether Setool2 or SemC. If one of two certificate is there, safe to unlock Bootloader. If No simlock certificate found, might be risky/problematic in unlocking bootloader process.
5)Download Necessary FTF files(called Flashtool Firmware) and ROM.Zip Files from the link of your desired ROM [To get Custom Kernel and CWM recovery flashing]
6)Unlocking Bootloader using Flashtools/Unlocking tools by senior 9luka5 [IF SIMLOCK CERTIFICATE FOUND] and Flash custom kernels, get to CWM recovery and flash ROM.zip..then reboot. First boot is longer abit, and if successful, will lead you to setup guide / homescreen.
Extra: If you wanna understand how things work or be done, you can visit my signature link for more reading materials. Although methods are older version abit, but trusted and Safer. Hope Helps. Cheers and Goodluck

After updating and installing xrecovery. You may try stock base rom like Fera NG, DonutHD etc. These are very cool.

dude, u got high expectation lol. u just bought the phone and u want to install the latest rom. possible.
ASK SOMEONE EXPERIENCED TO HELP YOU WITH THIS PROCESS. YOU CANT DO IT ALONE IF YOU JUST BOUGHT THE PHONE:
1) flash 2.1 stock rom
2) use z4root app to root ur phone
3) install busybox
4) unlock bootlaoder
5) install xRecovery
6) boot into xPrecovery
7) wipe date, cache, dalvik
8) fix permissions
9) install custom zip
10) choose the downlaoded zip file
11) flash the kernel and baseband files needed for ur rom (most likely two separate .ftf files: one for kernel one for baseband) using flashtool

Have you unlocked your bootloader? I suspect not. This is what flashtools is referencing.
Custom roms and mods that work on stock kernels can be installed on rooted devices.
Some mods/roms make such significant changes to Sony's builds that a new kernel is required (MIUI, CM, AOKP). To install a custom kernel you need to unlock your bootloader.
You may read the instructions provided by the author of the rom., to flash kernels, you need to unlock your bootloader. Seek and you'll see.
Is that right? lol

Now you’ve flashed one ROM on the Ray I can’t see you stopping
It doesn’t matter what WE recommend because your experience of which is the best ROM may be different to ours.
Try them all – I usually change mine once a month. But in my humble opinion, the most cutting edge, fully featured, experimental yet suitable for daily use ROM is PAC. My little Ray runs smoother than my wife’s Galaxy S2 and has so much more swagger – to borrow from AOKP.
so you recommend PAC rom ? actullay i want to stay with my stock based smooth (ASOP) ROM. if you know something then pls recommend me

Need Little Help

Hey guys,I own optimus one and I m used to rooting and stuff but my brother owns xperia mini pro so I need to install cyanogenmod (9 or10) whichever is stable.I had gone through various guides and stickies yet I want to be dead sure that I don't mess up my brothers handset. Its kinda new coz bootloader needs to be unlocked and also kernel image needed to be flashed separately unlike in optimus one.
Now I want help of you guys in the following manner like:-
1. My brothers mini pro is on ICS 4.1.B.0.587 and the rooting tutorial provided here for the said firmware
http://talk.sonymobile.com/thread/41119?start=0&tstart=0 is not clear to me coz it says that first I need to install some kernel [only mini mentioned here] then next I need to flash another kernel according to firmware. Can someone explain what is being done in this and why rooting is so complicated in this.
2. Certain ROM's say that you need to flash kernel first using flashtool
My query is that all ROM's that I flashed till now on optimus one included kernel and I only needed to flash ROM zip through cwm.. So do I need to flash kernel everytime I flash ROM!! and isn't there flashable zip for kernel too!!
3. FXP ROM's do not contain things like what's working and what's not, it only has issue tracker so it become difficult for new comer to know the bugs in ROM. Can anyone tell me the least bugs cm9 & cm10 ROM and what are the bugs present.
4. Lastly, should I proceed like this!!
i. Root device (though method isn't clear to me)
ii. unlock bootloader
iii. install cwm (I guess I can do this using flashtool)
iv. backup current ROM along with kernel (for future use,I know its optional)
v. flash kernel using flashtool
vi. flash ROM through cwm.
I m a quick learner and I just need some guidance on this new device (double checking coz its my bro's device) . Looking forward for support. Thanks

You needn't root first if you want to unlock bl, just unlock bl and flash a custom kernel (in most custom kernels cwm is included).
Backup your rom and install the rom...
hmmm....
1. Unlock Bootloader........
2. Flash Custom Kernel (all custom kernel is per-rooted and have CWM).......
3. Boot into CWM and Flash CM9 or CM10 (factory format/wipe dalvik/cache).....
4. Boot into Fastboot And Flash FXP kernel for CM9 or CM10.....
xperia phones aren't like sammy, lg or htc where recovery is a separate partition from kernel. in fact, by default xperia phones doesn't even have "stock recovery" like on other phone. by that we integrate cwm in kernel ramdisk.
and to answer the question:
1- flash custom kernel mean't for your phone only, never ever flash kernel intended for other phone. and its done via fastboot and should be flashed before flashing rom.
2- like i said u can't compare xperia phone with other phone like sammy etc, its different. kernel must be flash via fastboot.
3- for cm10, bugs that i notice is slow accelerator, but fixable with some text editing, and non working front camera for lww and minipro.
4- should be like this, according to order:
- unlock bootloader.
- flash kernel via fastboot.
- boot into cwm.
- backup rom if u want.
- wipe data, cache and dalvik cache. don't wipe system partition or u will get error when flashing rom later.
- flash rom, and gapps if its cm/aokp/pa rom.
- profit :good:
thank you guys.... this made me clear...
one last thing :- which kernel should I flash on stock 4.1.B.0.587 which is pre rooted and have cwm after unlocking bootloader.I mean the one compatible with above firmware and also do I need to do anything with baseband or will it be compatible. After this m ready to enter the custom xperia world
Remember to backup your stock rom before unlocking the bootloader as everything will be wiped clear.

No, i just meant that backup up your contacts, messages, apps (can be done through astro file manager) etc, before unlocking your bootloader because unlocking will wipe your data.
