Is it possible to downgrade the bootloader ? I installed the jkv beta from ssamsung and it changed my bootloader, i need to get my old one so i can get EXT SD function on cm7
best regards
You need to find a froyo firmware with the bootloader in the package and flash through ODIN. Search around on the forums... i think the bootloader is called Sbl.bin.
Can we flash bootloader alone without firmware?

It can be, the most "3 buttons combo" fix for Recovery and Download mode are based on this kind of flash.

I tested it and working with xperia arc 2.3.4 (.42) fw!
I suggest you changed the title something like "cmw recovery on locked bl and more". I think many want recovery with but hesitant to unlock bootloader. Thanks for posting.
works perfect on rooted stock arc locked bootloader
sounds wonderful. I shall try on mine too
Can I install ROM now from the dev section in the forum?
can confirm that this does not work on the Xperia acro IS11S
so does this allow a recovery menu for devices with locked bootloaders, does that mean we can flash custom firmware on these devices. if not what are the benefits of locked bootloaders having a recovery menu

If we install CWM using this method, is there a way to remove it if we need to claim the phone on warranty or anything?
Also can more people confirm this definitely works with stock fw, locked bootloader

Are you sure that'll work? You still have a locked bootloader so custom ROMs probably still won't work. I think it more for backing up stock ROMs and installing mods etc.
ah ok i guessss your right....can we flash themes?
I have no idea. I'd like to know actually. Would make it a lot easier to test things that may cause a boot loop and be able to just flash back to stock without a full reset.

You can't upload the CM7 because CM7 need another Kernel. CM7 don't working with the stock kernel! If you make change kernel you need the unlocked bootloader phone.
I think that this works:

Yes, but this is just a rom in ZIP file, just flash with CWM over the original stock rom. Test it if you have time!?
How about adding a (second) post / sticky in this Topic, with Roms, Tweaks etc. that work by CWM flashing... (locked bootloaders)
With the GS2 I just got the file, put it on Odin and it was done so I have no clue about HTC phones. My phone is unlocked but has my networks firmware on it and I cannot update to newer firmware unless I get the stock firmware I'm guessing. So I'm just wondering where I can get that and how I do it?
Thanx.

Just about everything on htc phones is done through custom recovery.
If you have bootloader unlocked the you will need to flash a custom recovery I recommend twrp. After that just make a backup then download and flash a rom.
You can download and flash roms with just the phone no computer needed once you have the custom recovery

No I mean my network doesn't lock the phone but you get their firmware which is annoying. I have no idea how to check the bootloader, never even heard of one before, everything was much easier with Samsung lol.

Custom ROMs are tweaked so more than likely it will be snappier and more battery efficient compared to stock ROMs. Also some custom ROMs have different themes, wallpaper or look than a stock ROM. The only ROM I know that doesn't have ANY visual changes is ARHD ROMs by mike1986.

You need to flash a custom recovery to be able to flash a custom ROM. Read the guide that was mentioned a couple of post above. The steps år basically like this.
Unlock the bootloader through the HTCdev website
Flash a custom recovery
Make a nandroid backup of your stock rom from recovery
Download and copy a custom ROM zip to the SD card
Flash the custom ROM from recovery
No, Samsung was not any easier to modify . I have rooted and modified several devices from both Samsung and HTC. You just have to learn the steps.

If you haven't unlocked bootloader then it is locked you can't root before you unlocked the boorloader

Hi im a tmobile user and have a locked bootloader I rooted and installed a.custom recovery
on my phone but every time I install a custom Rom I get soft brick I've done this three times
I've followed the direction but still the same thing I have no idea what else to do
Okay so first, download ftf and flash it using Flashtool. Then you can go back to pure stock:thumbup:

Ok I am not an expert but first thing is if u are flashing a custom kernel then your bootloader must be unlocked.Since you have a locked bootloader so u have to flash recovery for locked bootloaders only else ur phone will not boot.Also being on a locked bootloader, u cannot flash roms like aosp(cm,aokp,pac etc.) U can only flash stock based roms which don't require u to flash custom kernels.

How is OP supposed to flash it? bootloader needs to be unlocked doesn't it? He says he's having trouble with the OEM unlock. Bootloader, then custom recovery, then you can flash roms, or am I wrong?

You should flash the firmware from your phone, in this case if i'ts G6 Plus, It's EVERT, it's here on the forum.

For flashing custom recovery and custom Rom, you need unlocked bootloader, for flashing STOCK system you don't need it to be unlocked
