I recently rooted my s3 i9300 and was planning to flash CM10 to it.
In the install instruction it states the following: "Make sure you run stock ICS rom. We won't care if you didn't and your Wi-Fi isn't working."
I am currently running 4.1.1 JB, so my question if I should go back to ics and how. Or can i just flash CM10 over my stock 4.1.1?

No, don't worry about that. You don't need to go back to ICS.. Just download the latest version of CM10 from here. And flash it via CWM.
But first
Take a backup of your current rom using cwm (Just in case you don't like CM 10 and wanna go back to how your phone was)

Thank you very much!
Do you recommend I do a factory reset via cwm as well?

Yes, that is always advisable when installing roms.
PS: Download Google Apps for CM 10
Wipe data/factory reset
Wipe Cache Partition
Advanced > Wipe Dalvik Cache
Install CM10 Zip
Install Google Apps via CWM right after flashing CM10
In that order

I first installed CM 10 nightly, didn't really like it, so I thought about restoring my old backup and going back to stock ROM, but, when I booted the phone, the logo came up then it rebooted.
Then I flashed Xperia Ultimate HD 2.0.3, Installation went fine, but the logo stayed for like 5 seconds then it went into a black screen, kinda abit blue'er than black.
The LED light went light blue.
What should I do now?
Thanks.
Fixed!
Finally, I managed to fix it.
I did this:
Locked bootloader: http://forum.xda-developers.com/showthread.php?t=1134335
Unroot with Flashtool.
Flashed boot.img from CM10.
Flashed 562 Android build. (or something :s)
And then the phone booted up. :laugh:
After/Before restoring your Backup, did you flash the right kernel for the software version?

Just for your information:
If you want to flash a new rom, you have to flash a kernel that's compatible. So you do it like this:
1. Push rom zip (and gapps if needed) to sdcard
2. Boot in cwm and do a backup
3. Flash the new kernel (in the zip or if you can choose one, watch out: there are kernels for GINGERBREAD or ICECREAMSANDWICH and use the right one )
4. Boot in cwm
5. Wipe data/factory reset, wipe cache, advanced -> wipe dalvik cache
6. Install zip from sd card -> choose the zip
Reboot and you've got it
I installed 4.1.2 on my s2 gt i9100 no brand but will not start, crashes on startup with the samsung logo. Why?
I now have the phone down, I think I have to replace the 4.0.3
this is the tread http://forum.xda-developers.com/showthread.php?t=1544487
Did you use CWM recovery wipe? Maybe it's emmc brick bug?
It can't be a brick as it is turning on
And it's flashable with Odin, not CWM.

CWM doesn't have the emmc bug, Its a bug in the stock 4.0.4 recovery.

This is most likely because you have just flashed 4.1.2 without wiping old rom data. Its advised on just about every single rom thread to wipe before flash. If you dont want to lose apps/appdata then use Titanium Backup Pro.

you have made a backup of the app + system data with titanium. also save photos, music and video
I did not think to flash a firmware I had to clean everything, I thought it was enough to download the file, put the phone in download mode with odin and startare
now how do I proceed? I wipe the 3 as I did for the rom?

1) Put ur phone into dwnld mode and flash a stock ICS 4.0.3 firmware using ODIN to make ur phone up and running.
2) after that root ur phone by flashing the tar file of Siyah kernel v5.0.1 vide ODIN.
3) then reboot to siyah kernel recovery and wipe Data/factory reset and the wipe cache partition.
4)Dwnld the stock JB firmware from that link u provided and flash the same using ODIN
that way u will have a clean install of stock JB on ur phone
but if by dalal recovery without installing the 4.0.3 and do the wipe, and then install the 4.1.2 is not good?

u can give it a try that way and post ur Success/Failure feed back over here

He has no need to do what you said and install rom twice. All he needs to do is flash kernel like Siyah v6 beta4, reboot into download mode, wipe data and then flash his stock rom via download. No need to install 4.0.3 first its just waste of time.
and where can I download the file of Siyah kernel v5.0.1?you say the kernel?
I installed the 4.1.2 doing the wipe, and everything went ok.
so every time I install a new firmware should I do the wipe right?
and then I do not have siyah kernel but everything went well from recovery

Good:good:
Yes, its always better to do the wipes first for a clean install, as u can see in ur case itself
Enjoy the rom for now and no need to worry about siyah kernel for now
ok
however, once I had siyah then I removed
thank you very much for your help, I did not know I had to do so for the firmware
thank you very much

Recently I unrooted my alerady rooted I9100 and installed stock ROM,after few days again I rooted it and installed
custom ROM but now whenever I go to install stock base ROM like S4 for I9100 , NoteII mini etc...
it gets stuck on the samsung logo (earlier they were working ok), but this doesnt happen with other ROM's like CM,Carbon etc...
Can anyone suggest any solution or what I must have done wrong.
Thanks in Advance

Always do Wipe data Factory restore and wipe cache before going to Stock rom to Cm10 or any custom rom.

Yep I also did format/system along with the wipes but no luck is it due to recent changes to cwm's like when I was on stock I had rooted with Philz (touch) and then when I tried to install other stock base I was on other CWM (non touch)
basically I am very new in this flashing world...

I installed unofficial CM 11 on my SGS2 yesterday and wanted to switch back to Wanamlite JB 4.1.2 after experimenting with KK 4.4. But encountered bootloop after flashing JB 4.1.2.
Should I be doing something specific when reverting back to JB 4.1.2 from KK 4.4?

You need to wipe your cache and data, have you done that? It's easy to forget :/

I did. I wiped cache and data and got bootloop. Do I need to flash an older version of CWM recovery when I switched back to JB 4.1.2?
Did you do a nandroid backup before you installed kitKat on your phone? If you did then try restoring it to go back to your old rom.

format /system (advanced menu)
perform factory reset
install rom
again perform factory reset
reboot.
It should boot then.

hello,
After installing NeatROM 6.4, I am not able to restore the CWM backup of Jelly Bean 4.1.2.
A CWM restore of the Cyanogenmod 10.1.3, works fine though.
When restoring the JB backup, I get a boot loop on the logo.
Even after doing a wipe data/factory reset and wipe Dalvik cache, still the bootloop.
It was possible to flash the stock ROM (both ICS and JB), so phone is back to normal.
Just want to know if anybody came across this issue and what might be the cause if it and how can one resolve it.
Many thanks for your help.
regards,

Backups don't always work. The best way to restore stock is to download the stock rom for your region from sammobile.com or one of the other sites with stock firmware and flash it via odin.

OK. That could make sense. But I restored the JB Backup several times, before I installed NeatROM.
Could it be that a directory was changed / deleted / overwritten during the installation of NeatROM, thus giving me the bootloop?

I'm not sure what could have happened, but I always have a copy of the stock rom in .tar.md5 format so if I get into trouble I can always go into download mode and rescue my phone with odin......
I found this out the hard way on my S2 as well......
It turns out that CWM doesn't backup the Preload partition.....so when you try to restore the nandroid it simply won't work.....
