How can I easily revert back to original Froyo ROM from currently running cyanogenmod nightly ??
also with fresh install of original ROM will my cell get locked for AT&T sim again ??
Thanks.
odin one click to 2.1 use kies to go to 2.2
unlock should stick through the process, even though im on at&t i unlocked mine months ago, through all my flashing/building/messing stuff up/reflashing its still unlocked

Hi guy, i have a galaxy s i9000m (canadian bell version)
I had the phone flashed to 2.2 prior to unlocking it. Im woundering if i flashed back to jh2, will the unlcok still work?
I have successfully unlcocked other i9000m with the unlock tool
why dont try the samsung galaxy s unlock from the market?
I unlocked mined with that.
I have a similar problem: I updated to 2.2 and the marketplace app doesnt work for me. Where can i get the stock bell rom and will it even work if i go back to the old rom to get my unlock codes?
I just tried going back to stock as well as restoring a backup i had made of the stock rom, no luck still gives me errors.

You cannot downgrade your bootloader. I think you're stuck until someone finds a way to root the new HBOOT.
I just want to go back to the stock android 2.1 , then update it to 2.2 ofiicially without rooting
The 'custom ROM' you flashed is actually official FroYo. There would be no difference even if you downgraded and got official FroYo. (Its not possible yet as stated above anyway, but, just letting you know)
Via unlock, I am on TMobile network, running 2.2 on captivate (AT&T locked) with cognition v2.3. I want to upgrade to cognition 4.1.
Will I be able to keep my unlock or it will be removed?

Assuming reverse logic is true, you should be fine.
I have a vibrant that is unlocked from TMO and it has been upgraded and downgraded so many times is scary and still works fine.. As long as you unlocked before you upgraded to 2.2 your /efs data should get converted (the unlock gets converted as well) when you install your first 2.2 rom.
I recently bought a used captivate . The seller has advertised it as 2.1 .This will be my first android device and i have no idea what things should i do 1st .
i have the following questions:
1. if i get a device with Stock OS 2.1 ,should i directly update it to 2.2 with Kies Mini or first unlock it before upgrading to 2.2 .
Does the unlock process becomes difficult after an official 2.2 OR
The upgrade process becomes difficult after unlocking
2.since official 2.2 has been released there is no point in reading custom ROM threads .DO custom roms offer any advantage over the official 2.2?
3.Is tethering working on 2.2 ..i guess it was disabled on the lastest 2.1 update
4.HOW do i check if i got a phone with stock 2.1 and if it hasnt been flashed with custom roms and reverted back .This will be useful in troubleshooting if i get into any problems
personally a custom rom would be a better idea than stock 2.2, most custom ROMs are on 2.2.1. All preference though... I never personally liked the iphone-esque launcher of Samsung, so I tend to stay away from custom ROMs. Why would you go from a 2.2.1 version to a 2.2 filled with AT&T's bloatware.
Check phone info in settings to see what version it's on
And when you update to a new version it generally needs to be re-rooted especially if it's official.
In the Dev section you can find an Odin one-click to stock ROM
If you're on 2.1 you want to get your real official unlock code before you upgrade (once you upgrade you can't get this unlock code). Write the code down, just in case somehow the phone relocks (mine never has).
start reading. i cant STRESS that enough!!!!!
i read for 3 days before i flashed anything custom.
KNOW what you are doing so when you do mess up (we all do) you can properly explain what you screwed up...
start here,

then check out the stickies in each section of the captivate forum.

While it is easier to get the unlock code if the phone has never been flashed, it is far from impossible after.

not true. i unlocked on 2.2 last month. you just need a new version of your unlock program. or a different unlock program.
2.2 isnt new. ATT isnt the rest of the world. ATT was late. time for you ATT people to catch up to the rest of the world.
thanks for all the replies
There was a thread which said there are no workarounds for 2.2
how do i check if the seller has upgraded to 2.2 and then reverted back to stock 2.1 before selling me ? This will effect the unlocking process as there are many methods posted
What the official unlock code (is it through SGS Unlocker?)
Is the unlock code stored on phone or on SD card . i am not be getting the original SD card
Hi, I'm new here. I need help restoring my HTC One back to the stock ROM. It is with virgin mobile in Canada. I'm trying to unlock my phone from virgin but having trouble and figure it can be from being on a stock ROM.
I have been reading for about an hour and searching for the stock RUU. Before I forget, I'm running OMNI ROM on android 4.4.2 and have CWM recovery installed.
Anyways back to topic. I couldn't find any RUU's for my device but read on here that you can restore using a nandroid backup if you can find one. Now me and my brother both got an HTC One at the same time but I went through so many ROMs and customizing it. I started with CWM and made a back up of the stock rom but kept getting errors with some ROMs so switched to TWRP and couldn't use it anymore. With android 4.4 I needed to go back to CWM but in some point when tesering ROMs I only had 3GB free of space so did a wipe and fresh install so I don't think that the original back up is still there somewhere.
Anyways. I have my brothers HTC One here and that's stock. Nothing modified what so ever. Can I make a nandroid back up or use a tool to extract the firmware from his phone and somehow use it to restore my phone back to stock, unroot, relock boot loader and get rid of the *tampered* flag in fast boot?
The phones still on contract, only had it for like 4 months and thinking of giving it back and getting an upgrade to the One Max or when the One 2 comes out but I don't think Virgin mobile will allow me to since the phones been tampered with.
Hi. I have created a Canadian stock thread. See of it helps. It is linked in my signature
