As the title states, is there a way to flash a new rom without being tied down to a PC / laptop?
Bootloader's unlocked, rooted, it's strange how with this phone we're forced to stay locked down to a PC.
Have never flashed anything from the Original Dev section on this phone yet, would that be the same method as normal rom's like monx's and IHackers?
Cheers.
huh? TFTs are for returning to stock ROM and/or kernel and baseband, custom ROMs come in ZIP files which are flashable in recovery. What I do is download the ROM zip on my phone and flash it straight after via recovery, no need for a computer at all.

FTF's are not just for returning to stock, not at all, they're used to flash rom's too as the kernel and baseband needs to be flashed also.
Check out monx's thread, the instructions for install states to flash the rom and then without allowing a reboot, flash kernel and system (afaik)
Simply flashing the rom wouldn't be enough without flashing those files via flashtool.
What i'm trying to ascertain is do I have to do this every time as it's a pain in the backside.
Quote from Monx
LOCKED & UNLOCKED BOOTLOADER
BACKUP any critical data to microSD
Copy this rom zip package to microSD
Reboot in recovery, (do nandroid backup), do factory reset & install rom until finish
IGNORE RECOVERY INSTALLATION WARNING. SELECT NO & PROCEED AT THE END OF RECOVERY IF USING CWM RECOVERY
Skip (x) steps if u already running same base firmware with latest monxDIFIED base rom. Else, proceed.
(x) Turn off device. (Hold power button + vol up until vibrates 3 times) [or use recovery turn off device option, if any]
(x) Flash latest Sony's firmware (FTF) matching current latest monxDIFIED base rom using latest flashtools. UNCKECK all WIPE options and CHECK only SYSTEM & TA in EXCLUDE options.
(x) Disconnect USB cable & turn on phone. Done.
Notice how I write "and/or kernel and baseband"?
FTF only necessary if changing bases, don't need to flash every time going from ROMs on same base.

Because you wouldn't be performing a full wipe right?
Thing is I would never do a dirty flash over another rom, you're asking for problems if you do, so in which case I'm guessing that I'd need to use an FTF file to replace the files needed that aren't flashed with the rom right?
Thanks by the way.
Reason i'm asking all this is because this is the first phone that i've had were i've needed to be tied down to a PC to flash a rom, it's a bit crap really.

I used to have the HTC One X which required the same trouble-some computer steps.
The kernel and baseband don't even get affected when you do a full wipe, they're separate from the system, data, and cache partitions which gets wiped. Basically the stripped FTF holds the stock kernel and baseband needed to get compatible mobile signal and this only needs to be done once moving from base to base.
Going to and from ROMs with same base:
1. Full wipe
2. Flash ROM
ps. some ROMs flash their own kernel during ROM install i.e iHackers.

Nice one m8, that's put an end to my misery, cheers for that, makes a lot of sense now, i wasn't aware of how Sony rom's were flashed, it's strange as the bootloader is unlocked? What more is needed lol.
As for the one x, that's the only HTC i skipped and glad i did apparently they had a lot of problems with flashing and stuff, S-OFF.
Anyway, thanks m8.

THIS IS FOR I9020T ONLY! IF YOU DECIDE TO GET BRAVE AND TRY THIS ON AN I9020A, I9023 OR D720, MAY THE FORCE BE WITH YOU. I AM NOT RESPONSIBLE FOR ANY DAMAGE CAUSED TO ANY PHONE BY USING THIS ROM.
YOU MUST FLASH THIS ROM USING CLOCKWORKMOD RECOVERY. THIS WILL NOT FLASH USING THE STOCK ANDROID 3E RECOVERY AS THE ZIP FILE IS NOT SIGNED. I HAVE NOT TESTED IT ON OTHER RECOVERIES.
This is probably more for posterity now than anything else, however I have created a CWM-flashable full on ROM for the Nexus S Gingerbread firmware, version 2.3.2, build GRH78C. This is built exactly the same way that the full OTA ROM packages for 2.3.3 and 2.3.4 were built.
Some notes:
1. Flashing this ZIP will remove ClockworkMod Recovery on first boot. Android 2.3.2 contains a script that automatically overwrites alternate recoveries with the stock Android 3e recovery each time you reboot your phone. The script is located in /system/etc/install-recovery.sh. If you root the ROM, you can rename this file to avoid flashing the stock recovery on each reboot.
2. Flashing this ZIP will overwrite your bootloader and radio, restoring them to I9020XXJK1 and I9020XXJK8 respectively. These are the versions that came stock with GRH78C.
3. GRH78C is receiving OTA updates. As of this writing, the latest version of Android is 2.3.4, and Google is pushing an OTA update for 2.3.2 to 2.3.4.
4. This ZIP will NOT clear your user data or cache. For users running a stock ROM, I would highly suggest clearing your data and cache manually as sometimes downgrading without clearing data and cache can cause problems. If you are coming from a non-stock ROM, you are required to clear your data and cache or the ROM will not boot.
5. Since writing NFC tags wasn't introduced until GRI40/2.3.3, the Tags app is read-only.
6. There is no video chatting through Google Talk. This feature was not introduced until GRJ22/2.3.4.
Instructions:
1. Download the Stock GRH78C ROM package here.
2. Copy it to the root of your USB storage.
3. Reboot into ClockworkMod Recovery (or flash it).
4. Select "Install ZIP From SD Card"
5. Select "Choose ZIP"
6. Find the ZIP file and select it.
7. Wait for it to finish.
8. Wipe data and cache (optional but HIGHLY recommended for stock ROM users and REQUIRED for non-stock ROM users)
9. Reboot and have fun.
Reserved...just in case.
Thank You will post results if needed,i doubt it,again thank you very much,ping33tx
I can access the bootloader, I can access the clockwordrecovery, odin recognizes the device, but I can not access the intern sd.
I can only try to restore by odin

Wanted to flash this ROM, just wanted you to confirm that yours is an i9020A, not i9020T, therefore that's the reason why it won't turn on now.
Sorry for your phone by the way.
that could be the reason, i got this phone for very cheap and it was soft bricked so i had no idea if it was 9020a or 9020t (no box with it)
if this is the case, what can i do, USB jig or jtag?
Can you boot it to bootloader?
From off position, try Vol UP + Power.
If you can see the Android logo and 4 menu options, you got yourself a great deal.

He doesn't need to. If he can get to the bootloader, he can flash and boot a recovery via fastboot.
No guys, seems i got myself in a mess. It is indeed a i9020a (the info under battery was erased so i didnt know0 and i flashed the i9020t rom in this thread (different radios)
so this thing is HARD bricked, screen won't turn on, no bootloader, nothing, tried to get it into download mode (even without screen turning on) assuming it was working, but odin doesn't realize its there
so i think my only solution is jtag. I can buy a usb jig but I think that usb jigs dont do anything for hard bricked phones, am i right
Much thanks for your help.
Hey everyone, my phone is running 2.3.5 of Android and it is branded to Orange. My build number (and kernel version) is BVJVC. I cannot find the right cf root for me. There doesnt seem to be any for JVC. Can anyone help?

Are you planning on rooting to then flash a custom rom or do you just need root access?
If you are planning on changing roms then just flash a pre rooted firmware or one that has a root solution available.
What do you want cf-root for? If you want root to you can flash a custom ROM it doesn't really matter which one you use. If you want it to run you current stock ROM with root then it is better to run the correct one. I cannot find that one either. Good luck.

There's no cf-root for JVC. I've only found a french forum with a very tricky way to root... far easier to flash another ROM that has cf-root. But come on, let's have a little more fun... ICS!
I want to change rom. Can I just flash any rom compatible with galaxy s i9000 or do you have to have compatible kernels? I have seen tutorials where it says to flash to something specific before flashing to the final one. If it's possible can someone send me a link to a custom pre-rooted rom which I can flash straight away onto my phone?

most of the roms come with a kernel. You can then flash other kernels but these do need to be comparable. I have team oceans 4.2 for example. This comes with its own kernel but I have installed semaphore 0.9.1 which sheet a lot of testing has been the best fit for my use. Hope that makes sense. If you have something particular inn mind let us know and we can help more

This is a stock firmware and the Odin 512.pit that I use when going back to stock and root is easily applied. It is a good idea to save these on your computer if (or when) things go wrong .
Can I just flash a rom with its custom kernel over my orange stock rom and it's kernel? They don't have to be similar in any way? Also, so I don't need root access to flash a custom rom.
Sent from my GT-I9000 using XDA App
You will need root access to flash custom roms as most have to be flashed by cwm(which you will get when you root your phone)
This brings me back to my original problem, people told me to flash a rom with compatible CF-root, but to flash i need to root? So i am stuck in a little circle?
Or does this only apply to custom roms and not flashing stock roms?
You flash Cf-root with Odin. This gives you root. You then flash custom ROM through recovery on your phone. As mentioned above if you want root to flash custom ROM then you need root it does not really matter which cf-root you use. Just follow instructions in Cf-root thread then follow instructions from ROM thread you want to flash.
If you want to use stock ROM with cf-root then it needs to be compatible.

Help! I don't know which file to pick! The filenames confuse me!
First thing: don't panic! It's all rather easy, and you won't easily do something bad! I am personally attentive to use the exact same version as the ROM I am running, but it's not that important.
First, go to Settings -> About phone -> Build number. It should say something like FROYO.xxJPy. It's primarily the JPy that we are interested in. Try to match that with a download link available in this (and the next few) posts. Some of the downloads dont just have JPy file name format, but are called xx_xxx_JPy.
Find the one that is closest to yours, if yours is not present, and flash that one.
If you are just installing CF-Root to flash a custom ROM like Darky, make sure you have ROM Manager already installed, ClockworkMod flashed, then simply install the latest CF-Root, reboot once normally, then reboot in recovery and run the Darky update.zip. In this case it does NOT need to be a near match at all!
Before you start it is a good idea to download your stock rom or another one for your phone from here. http://www.sammobile.com/firmware/?page=3&t=1&o=1&m=GT-I9000&r=-1#modelsa Then where it says region click your country.
I recommend getting everything you need before you start. So make sure you Odin, a 512 pit file & your stock rom with the PDA, Phone & CSC files. There are plenty instructions for getting back to stock if you search.
Next get the ROM you want & the kernel you want.
Now that you have everything you are ready to go.
My process is as follows.
1. Remove SD Card, some say to remove sim but I have never done this.
2. Turn on phone & turn on USB debugging.
3. Connect phone to usb & copy everything on my internal sd card onto my pc. (I have a samsung folder & create a folder with the date and put everything in there - just in case)
4. (USB) Disconnect your phone from your computer
5. shut down phone.
6. Follow cf-root thread instructions.
7. Unzip the attached CF-Root-xxx-vX.X.zip
8. Start ODIN
9. Click the PDA button, and select CF-Root-xxx-vX.X.tar
10. Put your phone in download mode (power on, volume down, home button)
11. (USB) Connect the phone to your computer
12. Make sure repartition is NOT checked
13. Click the START button
14. Wait for the phone to reboot
15. Done (if it took you more than 30 seconds, you need practise!)
Now you have root & cf-root. Restart phone. Next step is generally as follows.
1. Start phone.
2. Connect phone to pc.
3. copy files you wish to flash onto root of internal sd card. in my case team icssgs 4.2 & semaphore 0.9.1
4. (USB) Disconnect your phone from your computer
5. restart phone into recovery.
NB. Make sure to do a backup at this point and ensure you have a copy of your efs folder somewhere!!! - if for some reason your IMEI number is corrupted you will need this
6. factory reset & clear cache
7. advanced button -> clear dalvik cache.
8. back & choose install zip from sd card
9. choose zip from sd card.
10 .select the zip file (in my case team icssgs 4.2)
11. Choose yes- install... zip name
12. repeat steps 8-11 and select semaphore kernel.
13. factory reset & clear cache
14. advanced button -> clear dalvik cache.
15. reboot phone. Reboot can sometime take a while. sometimes you may need to do this twice.
Semaphore: http://forum.xda-developers.com/showthread.php?t=1468795
Team ICSSGS: http://forum.xda-developers.com/showthread.php?t=1398223
If no luck then reinstall stock rom using odin making sure to use all three files & pit file with repartition checked.
Please note I am still fairly new at this so it may not be perfect & you should always rather follow instructions from the thread of the ROM you wish to flash
Hopefully that's it. Don't think I left anything out.

Ok, let's clear things up a little. Every rom has its own kernel, let's say the default kernel of that ROM. There are stock Roms, which are those official of Samsung. Those come with its own kernel, but not rooted.
Now: there are some stock roms, of which some guys have managed to modify its kernel just to be able to have root access, and to have a modified version of the recovery: ClockWorkMod recovery.
There are other kernels, though. Kernels that people develope to improve those default kernels that come with stock kernels. But improve performance comes with (perhaps) less stability (actually that's not completely true, as cooked kernels also improve stability, and are in general far better than stock ones). What is true is that not every cooked kernel works with every rom, you have to make sure it works with what you want.
You definitely don't need to have root access to flash, but you do in order to make those highly important security backups! You can have root without flashing kernel.
Now, what are those roms that flash over other roms...? Generally cooked roms are stock roms modified to improve them. But they still use a lot of the stock roms system, that's why cooked roms have to be flash only over that rom they are based on. You still don't need to be root to flash those roms, but generally you do need ClockWorkMod recovery, that's why you need to flash cf-root kernel prior flashing a cooked rom. Or perhaps the cooked rom do not come with a modified/rooted kernel and you still needs to change the kernel (but usually they already come with a rooted kernel)
Hope that helps you even a little to know what do you want to do!
Thanks for the help everyone. I am going to flash an unbranded stock rom to get out of this orange rom. Would this tutorial work to debrand my phone?

Hi,
I have some experience with ROMing but I really do only basic staff. First of all, info:
Device is SGS1, with an Israeli operator stock ROM (2.2), not rooted, not SIM free.
Never messed with an SGS before, only Atrix and used to doing everything easily with ROM Manager but on SGS I'm reading about Udin, flash stock before custom ROMs etc and decided to stop and ask...
Is it possible to simply, root, install ROM Manager, flash CWM recovery and get going (nandroid and full wipe before installation of course)? This is what I did on the Atrix (with the addition of unlocking the BL which I understood is not needed here)
Again, I just want basic ROM flashing the way I am used to with the Atrix
Thanks!
You can enter the recovery with the stock ROM. Power off your phone,then when its completely off,hold volume up+home key+power button then wait for the recovery to show up.
Not following you.
The device doesn't even have root. Is the BL really unlocked from stock? Is it ok to do everything with ROM Manager all the time as long as I do a full wipe?

The easiest way would be flashing a Gringerbred Firmeware that is alerady rooted.
Try and follow these instructions: http://www.darkyrom.com/index.php?threads/odin-darkyrom-10-2-resurrection-gt-i9000.4272/
After installing that Rom, your Phone will have unlocked BL, Root-rights and other Stuff You'll need for flashing.
Just give it a try you can use Rom Manager as well after following and flashing that Rom
Edit: If you flashed that custom Rom you are abel to flash all other Roms like these Stock Roms: http://forum.xda-developers.com/showthread.php?t=948790

Hi There,
Just wondering if anyone had any ideas why my phone refuses to co-operate!
Basically, after getting bored of the stock rom when I first got my phone, I somehow managed to install a CM based rom. That worked, but I got bored of the fact that the camera never seemed to work right, and some apps didn't work/ were graphically buggy. Assuming it was just a badly ported graphics driver or whatever, I found a way, using FlashTool, to revert to the stock rom (C6603_10.3.1.A.0.244_Generic UK to be precise). I wasn't sure exactly what it did, but it was back how it used to be. sorted.
So, since kitkat made it's way to the XZ, I thought I'd try one of those roms, being the curious bugger that I am. The process I ended up going with eventually was:
>Downgrading Kernel to a lower version because the root explot wouldn't work on 10.3.1.A.0.244
>Rooting using "DooMLoRD_Easy-Rooting-Toolkit_v18"
>Upgrading kernel to one that would accept a recovery
>Installing TWRP
>Booting into recovery, CWM appeared instead. Strange, I thought. Oddly, mount USB wouldn't work at all, so I had to boot the phone back up to transfer the kitkat rom over
>Trying to flash the rom gave me an error number 7
>Boot Loop, at which point I just flashed 10.3.1.A.0.244 again.
I've tried this twice now, first with DooM Kernel, and then once with a different one. Neither CWM or TWRP have worked properly. Any help? Or am I just cursed?
Cheers
Tried this again, did literally everything I could think of and still no dice. Help? Have I somehow forced my phone to be on stock software forever?
If you dont unlock your bootloader, you can not use any kind of custom kernel.
That means aosp or aokp based firmwares can not run over locked bootloader.
Locked bootloader checks sign of kernel, if not certificated you will stuck on bootloop.
If you want to use any kind of custom rom... basicly.
1. Backup ta partition. " so you can revert any time you want."
2. Copy firmware zip file tou your internal or external sdcard.
3. Flash custom kernel. "Most of kernel have recovery option build in".
4. Boot in recovery mod. "Mostly press volume down while booting"
5. Insall custom rom.
6.a wipe dalvik-cache
6.b factory reset
Old setting might work or not with new rom. So first try to wipe dalvik- cache. If you stuck on boot loop or any kind of problem, just boot in recovery again and run factory reset.

Hey, thanks for your reply!
I had unlocked the bootloader when I first got the phone and just assumed it would be permanent. Would flashing it back to stock firmware re-lock the bootloader?
But yes, assuming my boot loader is still unlocked ( I have tried to check and it doesn't seem to be locked) I have been through those steps basically. I am fine to flash a kernel with a recovery but the recovery never works properly/ at all. I can root the phone no problem though.
Best to extract the boot.img from the zip file of the ROM you want to flash, and flash that first. Then flash the ROM from its recovery.

Cheers, I'll give that a go - I was under the impression that you weren't supposed to flash kernels that weren't designed for the currently installed ROM though? It just seems that any kernel I flash isn't working properly so I didn't think doing that would play any nicer with the phone

You're not actually going to boot into your current rom after flashing the kernel.
Flash the kernel via fastboot, then boot into recovery and flash the rom.
All this should be covered in the installation instructions of whatever rom you're trying to flash in any case....
Sent from my C6603 using Tapatalk
Well, that seems to have done it! Thanks very much for your help.
So, I guess the moral here is that if you're on stock and need a recovery to flash a new ROM, always use the boot.img from the ROM you'll be using.
Thanks again - I'd never seen that said before but quite possibly I wasn't paying attention!

Flashing a kernel doesn't auto wipe data. Since you're completely stock right now, I am guessing you'll be flashing the kernel via fastboot so you should be fine. As for boot loop errors, the kernel's meant for stock based roms so it shouldn't be a problem. I remember using it with Existenz. Worse case scenario, you'll have to reflash the kernel part from the stock firmware with Flashtool if things go wrong. Alternatively you could take a backup of your kernel via Rashr since you're already rooted.
Speaking of Rashr, you could use it to flash a recovery in your Fota partition which doesn't go away unless and until you remove it using stock firmware. This means that no matter which kernel or rom you flash, you'll always have a working recovery to get yourself out of trouble. You can take a complete nandroid backup of your system before even trying Williams kernel and in the off chance your phone is stuck in a bootloop, you can just restore your nandroid backup and you'll be back to stock.
If you're still worried about your data, just get Titanium backup and make a backup before you proceed. I have switched over a dozen roms in the past few months only because of it. Imagine setting up 30-40 apps every time you migrate to a different rom

If I am not mistaken, SP like most older Xperia phones (not sure about the new ones) does not have a stock recovery nor does it have a recovery partition. The recovery is part of the kernel (the boot.img file or the .elf file). So when you flash a kernel, you are flashing the recovery along with it. This is why people flash a recovery in the Fota kernel partition since its a separate partition and is not overwritten while flashing other roms or kernels. A recovery flashed in the fota partition becomes your primary and only visible recovery irrespective of how many recoveries came bundled with the kernel you flashed. The only way to remove it is by flashing stock firmware or to be more specific, the fota kernel from the stock firmware. If you need it, you can find it here :

Now since your phone's already unlocked and rooted, go grab Rashr from the playstore and use it to flash the latest Twrp from here :

This way you will have a permanent recovery which you can use to take a nandroid backup before you try new roms or kernels and restore it if things go wrong.
Your other option is to flash the kernel via fastboot but remember if you flash another rom, the existing kernel will be overwritten by the kernel that came with the rom. It becomes really cumbersome when you are trying different roms. Another reason to flash a recovery in the Fota partition.
As for a new kernel speeding things up, yeah it helps. The first link is also the main thread for Tangerine kernel which has CPU overclocking and governor options and a bunch of other tweaks to improve performance but its only for LP roms. If you wanna stay stock, you can try the Williams kernel. Doesn't have as many features as the Tangerine kernel but more than the stock kernel. If you know which tweaks to make, I am sure you can gain a performance boost from either.
