How do I do it?

Flash it to stock using the downgrade tools listed here in the forums.

And howI get back then to the stock recovery?

Do exactly like I said, flash using the downgrade tool to stock. Means just that, it will flash everything to stock. EVERYTHING WILL BE STOCK.

But will it update back to an A501 rom afterwards??
Was wondering, if I flashed the update.zip file using CWM, what would happen as I'm replacing the rooted CFW with a stock firmware that doesn't have CWM in it. Bricksville, do you think or it just wouldn't flash?

flash rom with stock recovery?

simple question. can i flash flexreaper rom with stock ics 4.0.3 recovery? or do i have to unlock bootloader and install custom recovery first? i have limited access to a pc and just got rooted this morning
You should be able to. Be sure to flash the honeycomb kernel parts immediately after flashing the ROM.

simple answer: no you cannot flash much of anything with the stock recovery.
If you want flexreaper then yes its best to flash the patched bootloader. Have the rom on yr sdcard ready to install once you've flashed the bootloader/custom recovery.
You can use the locked bootloader (3.01) with some of the flexreaper roms but be warned, its not the optimal solution. If you go this route you will need acer recovery installer to flash a custom recovery first.

If you really want the ring you'll need to update the BL
Do you have yr cpuid from HC or an old HC backup??
any reason you're not too keen to flash???
No I never had the Hc uid I updated to ota straight out of the box. I have my current uid tho. it's not that I'm against flashing I just have limited access to a PC and to install programs and go through the whole process with someone elses PC is basically unreasonable.

yeh fair enough. I ran stock OTA ics for a month or so and was reasonably happy with it...civato's stock ics rom was better though...and as far as his flex series of roms go they are the absolute best!!

I know it. I can see the features and the overwhelming recognition on YouTube and any Google search of a500 room. I'm just looking for the magical update.zip file that will cure all my shortcomings as far as the iconia goes. Thanks for the help friend.

How to update android version when on a custom ROM?

So I am using CM10.1 with CWM recovery. What will I have to do when a new version of Android comes out? (4.2.3 or 5.0)
And will I lose my root access?

Either flash a new ROM that's built on the new version, or go back to stock.

And to flash that ROM, do you have to get new bootloader and baseband or what?
And go back to stock: do you mean to flash the factory image, or can you also get OTA updates by restoring a nandroid backup of the stock rom?
once you are rooted, unlocked and with custom recovery changing ROMs is as simple as puting zip onto your devices' internal storage and flashing it through recovery. you COULD be asked to flash a newer radio version, however it is not that common.
no OTA when rooted, going back to stock only with facotry images.
anyway 5.0 will be availabale on custom ROMs shortly after or even before official google OTA so no need to unroot.

So when 5.0 comes out, I just have to wait a day and flash a new CM version without flashing a new bootloader or radio?
And will it directly be stable?

Android 5.0 is far away by now, and nobody can tell you yet about stability
i´m sure it will get announced, just check the CM thread and read about (possible) bugs

As long as you read threads properly you'll know whether or not anything extra needs to be flashed. Even if there is something you need to flash in the future, it should be fairly easy. Normally a flashable .zip is released soon after the official release so you won't even need a PC. Personally I think it's useless to worry about it right now.

Radios and boot loaders are completely separate from ROMs. You have to specifically flash a radio or boot loader separately. But no, you should not need to flash them but it would be worthwhile if a newer version came out

I am a bit scared of flashing bootloader and baseband, because I read someone who flashed a wrong one and his phone completely got bricked. Some other guy said in that thread why would you manually flash a bootloader..

If I restore my Nandroid backup of 4.2.2 stock ROM, am I able to get OTA update? (I dont care if I would lose root, the question is if its possible ) or is it impossible since I am running CWM recovery?

you have made alterations to your phone so its not longer stock. the file you are flashing is for a stock rom and to be flashed in a stock recovery. to flash the update simply re-flash a stock recovery and allow the update to go through. you can also simply wait and flash an updated custom stock rom.
Edit: link deleted....may confuse you
Edit2: Using the toolkits you should be able to find the stock recovery image and flash it back

Odin.
It will let you flash back to the stock ROM. If you are on the 4.4 bootloader though you can only go back so far. You can't go back to 4.2. I'm not sure about 4.3.
You can also restore the Nandroid backup of your stock rom that you should have made before you flashed CyanogenMod

You need to use the search feature here on xda. This is probably the single most covered topic in Samsung forums. There are dozens of very detailed guides on odin and how to use it.
There is even one stickied to the help posts at the top of this forum.
