Downgrade to 2.2

Hello,
I am on CM 7.2 and wish to downgrade to 2.2.
I am German and need the German Stock Rom. If anybody could help me with downgrading and finding the right bootloader I would be very thankful.

Hi, if you want to go down, just flash stock 2.2 with Odin.
You can download the package here:http://www.sammobile.com/forum/showthread.php?t=31

EDIT: Make sure you DL the european version. It has german language.

Thank you. I tried it some time ago and my Gio bricked because of the wrong bootloader? Whatever this is what they said to me. But now I am not quite sure which 2.2.1 Rom I should pick.
Can you tell me which one is best?
I think it's because its one packaged. Is there a Froyo Rom that isn't one packaged?

If its one package, tick the ''one package option in Odin and just select your file in one package slot.
I dont think that One package ROM would brick your phone easier than Multi package one.
I would take S5660XXKC6 Rom since its latest Froyo (2.2) for Gio
If you bricked earlier, it may be wrong ROM for your device.

Ah I got it. Thank you.

I just downgraded my Gio from CM 7.2 to official 2.3.6. It was one package and didn't brick my set. Just follow the procedure and you're good to go.

Hello,
Could you give me more details on the procedure? Btw, where did you find the link for the official 2.3.6?
Thanks

root ur su640

after updating my su640 to v10i,
i cant root it,
but this one works.

Good to know! I ended up just downloading the v10f .kdz when I needed to flash the SU640 rom to my Nitro in order to recover from bricking, but if this will root the latest SU640 rom that's great

Which rom is better - stock AT&T's or latest SU640 (v10i)?
And I wanna try the SU640 rom, will it work with AT&T's baseband?

Holy crap, you know I never tried actually just flashing the Nitro baseband and firmware onto the SU640 rom. I wouldn't recommend it, though, but if you're feeling adventurous, I'd love to hear the results. I think it's going to be possible to start working on AOSP roms pretty soon and maybe even start trying to port CM9.

Can anyone upload the latest SU640 rom (v10i)? I wanna try it on my P930.
Malnilion,
I liked the SU640 (v10f) rom more than AT&T's stock rom, but I haven't wi-fi on SU640, and I think the problem with a korean baseband. So I wanna try a korean rom with an american baseband. If it will work, it will be great.

I think the relevant images you'll want to flash back after you get to the SU640 rom are the baseband (for phone and data) and firmware (for wifi), but I could be wrong about what the firmware image does.

10i rom

You have a Telus P935 phone with the AT&T P930 leaked ICS v18f ROM installed on it. All the P93x devices are identical, so there's nothing wrong with having that installed on that device.
If you want to install custom ROMs, you will need to follow the unbricking guide to downgrade to Gingerbread. From there you can install CWM and then flash to any P93x ROM you want.
If you only want root and you are happy with LG's ICS ROM, then I'd actually recommend that you update your phone to the newest Telus ICS ROM which is improved over the one you have installed. You can root it easily as well, however you can't install CWM from any of the ICS ROMs.

Can you clarify if you care about custom ROMs or not? Or are you happy with rooted ICS from LG?

Could you give me a link to the oficial 4.0.4 update because the gyde you sent me has the firmware that i already have installed in it
Sent from my Desire HD

Install USB driver then software update from that page.
After you have the new update, do a factory reset (hold volume down + power button after turning phone off).
Then to root, do this: http://forum.xda-developers.com/showthread.php?t=1835946

I am new to this community site. I own a LG Optimus P350 phone.. its Android version is the default 2.2 Froyo as provided by the manufacturer. Few days back i rooted the phone using Gingerbrek.. Now i want to upgrade my Android version. Firstly i want to ask which ROM would be suitable for my cell phone.. and what are the steps to do upgrade the ROM? Also i want to ask is how do i move the factory installed apps in my cellphone (like facebook, etc) to SD card since my phone is already rooted... please go easy with the language i am a noob with such stuff so far... I did try looking out for the solution in other threads but could not find the answer (or maybe couldn't understand it )...

There you have the oficial CyanogenMod 7 rom support, instalation and development issues support.
In my opinion it is the best 2.3 alternative rom for p350.
The steps i know only in portuguese, but i believe i will find it in this link too.
The factory installed apps, the most one you will install with a Google package inside this link too.
The others you can download again on play store.

following a different guide i was trying to install CM Invasion V2 ROM.. i never got to the flashing ROM part... i was backing up the current ROM unsing ROM manager and my cell fone bricked... after banging my head... looking for solutions on the net and again banging my head... i finally was able to revive my cell fone (using kdz updater)... all this is a risky business
can anyone give me a near perfect guide for flashing ROM without using ROM manager.. please..

You'll have to flash a custom recovery first. Amonra is very stable. Then you can make a nandroid backup of your current rom from the recovery for you to go back to. Flash the rom you like and enjoy. If you need to do back to your original rom, just restore back from your nandroid backup

now flash recovery by going on thread then do steps
for flashing roms do following steps on recovery
1.creat nandroid backup only once not for everytime you flash
2.then go in wipe section and wipe all data
3.then go to flash zip manu and find rom then flash
4.sometimes some rom needs advanced steps for flashing like cm 7 official needs to format/system(steps for it it mentioned by the developer on his thread)
done reboot then enjoy flashing.
hope this will help you...........................
in future do not install recovery from rom manager it will brick your phone untill it gets perfect for our device

Remember we have a wiki page for this phone with an all-in-one guide for modifying it (rooting, recovery, custom rom installation, troubleshooting). I try to keep it updated, nice and clean (kinda hard some times).
About Android versions: The Optimus ME comes with Froyo (2.2) there is no other official firmware for it. CyanogenMod 7 is based on Gingerbread (2.3) which now has official support and is working pretty good now (yes, previous versions were slow, buggy but now they're pretty stable)... Honeycomb (3.0) is only for tablets, so it's not coming to P350. CyanogenMod 9 is based on Ice Cream Sandwich (4.0), which for this device is still a work in progress, so don't expect a timeline nor a soon release. CyanogenMod 10 based on Jelly Bean (4.1) is still a myth for the P350...
I hope to have answered your questions...

Install roms ??

hey i have just rooted my phone but if i suddenly choose to install a new rom in the future, will i still have the memo function ?

..............................have you unlocked the bootloader too?please do it as fast as you can,if you don't want to get into "certificate security error".
If you flash a custom rom based on LG firmware,yes you have all the functions. If you flash a CM based rom,no,you will lose every LG goodies. You decide what you want/need.
Consider this the first and last warning about unlocking the bootloader.I will ignore any other discussion on this matter.i don't like repeating myself.

the bootloader is alredy unlocked but thx for the answer.
and another newbie question - how can is ee if it is the same firmware as lg ?
i have rooted and oc´de my other htc incredible s, so i am not completly new

We have only 3 roms based on lg fw. Look on faq. Come on guys,think a litle. Do you think you are the first to have this phone?this questions have already been answered.
Sent from stock LG E975/smart phones,dumb people.

u have to unlockbootloader by freegee on playstore. and do guide about that rom of thread that u want to flash.
