[TUTORIAL]LG Optimus one P500 with stock 2.3.3. ROM

After so many nights without sleep, i found solution for rooting new LG P500 official rom update.
DO THIS ON YOUR OWN RISK, I WILL HAVE NO LIABILITY IF YOU BRICK YOUR PHONE !!!
Read instructions carefully
First of all, download archive from here and extract it to your desktop
And download driver pack from here
1. Back up all data with ASTRO file manager, you can find it on market.
2. Hard reset your phone either with system->privacy->erase all data or turning your phone off, and holding HOME,VOLUME DOWN and POWER BUTTON.
3. After phone boots up, you have clean file system, then go to Applications, and turn on USB Debugging mode
NOW THE FUNNY PART
1. Connect your phone with usb cables, make sure you have installed all the drivers needed, and connect phone in DEBUGGING Mode (provided a bit upper on this post)
2. In the extracted folder called root on your desktop, go to ADB folder and start cmd7.exe if u run win7 or cmdXP.exe (run as administrator in both options) if ur pc runs win XP. (your address bar should like something like this: C:\Documents and Settings\YOUR NAME HERE\Desktop\root\ADB
3. After starting cmd7 or cmdXP, type following commands
Code:
adb devices
then
Code:
adb shell
(symbol will change to $ or #) and copy paste following command into your terminal
Code:
echo 1 > /data/local/lge_adb.conf
4. After doing this, REBOOT YOUR PHONE
5. After reboot, go to root folder on desktop again, and start SuperOneClick.exe
6. Select GingerBreak method and press root button
7. After few seconds VOILA !!! You have rooted Optimus One.
8. REBOOT PHONE and update superuser app from market (mine was updated automatically)
To unroot device, follow steps from 1 to 6 in FUNNY PART and select unroot instead gingerbreak. and you will have unrooted device
I tried to root all kinds with android SDK and many others, and always had problems with force close. Running on this method for 3 days, and have no errors.
This is my tutorial, if u consider it helpfull, think about donating for cofee or beer.
Comments, Questions... post it below, i will read them and answer ASAP
EDIT : If you want to have beautiful CRT OFF Animation on your phone read tut here be sure to backup phonebook mine was deleted, but now i have crt off animation, which i looooove and think that is the second best thing to do after rooting
VIDEO IS LOCATED HERE

Thanks for your effort

Hi, just "superusered" my p500, awesome. Thanks for the tutorial.

Dude nice tutorial... BTW Does this metod work with older version of Android on Optimus One (because I have one Optimus One with Gingerbread, and one with Froyo)...
GBU and all Croatians

I would like to write in croatian, but... ok, i had two files on my comp. for older versions, but, i rooted mine 2.2.2 with gingerbreak file, i can post tutorial, or if u want to send u files and tut on mail.

corrected in post, device MUST be in debugging mode, thanks for correction

i tried the above method and was successful but the problem is that superuser app crashes when some other apps require root access..and more over setcpu is not working, only clocks stock mhz...

Try EXACTLY as written, because if you don't do like it is mentioned above, root will be wrong, and u will have app.crash on superuser. If Everything is done by my tut, your superuser app will be updated and phone rooted.
Try again, reading row by row

Hi, today i rooted my Optimus One with 2.3.3 but i have one problem - Android Market don't work (Server error, try again later (...) - something like this).
How can i fix it ?
I think that i solved it.
I replaced SuperUser.apk with new one, downloaded from hxxp://androidsu.com/superuser/ and now everything seems to work correctly

Worked like a charm. Thank you

Getting SU error everytime I try to do anything on Titanium Backup, even after I updated SU. Any thoughts?
EDIT: Seems that, besides updating the SU app, I also needed to update the binary through SU itself. It seems to be working fine now. Thnx!

I succeeded too..

wow! worked like a charm. followed everthing exactly, and no problem has been encountered. thanks a lot.

Brilliant
Hello,
This worked perfectly, i now have root.
I must say i did not hard reset my phone (step 2) and still worked.
Thanks uploader for this beautiful tool
Cheers,

ok, if you are newbie, rooting is not necessary, but if you already have rooted phone it is ok. Go to market on your mobile and download "Android booster" easy tool to keep your phone in performance state. you can see about it here, and it is free

SuperOneClick 2.3.2 Root Attempt LG Optimus Net
I am running Android 2.3.4 on a LG Optimus Net L45C Smart Phone used under the NET10 (owned by Tracfone) service.
Following the instructions from the SuperOneClick author regarding LG phones and 2.3.2 I get as far as the following statement in the right pane of SuperOneClick 2.3.2 :
Killing ADB and restarting as root ... enjoy!
When I look on the Smart Phone in the Android Tab, There is no SU icon that appears prior to rebooting the phone. After rebooting the phone there is no SU icon that appears. The process was repeated 3 times with the same result: The phone is not rooted. Anyone with similar experience?
The attached pdf file shows the output from the right and left panes of SuperOneClick 2.3.2 during the root attempts.
SuperOneClick setting used was for Alternate ADB Parser.

Did you try using unlockroot method?

Rooting
For the LG Optimus Net LG L45C, you will need to use Unlockroot from Unlockroot.com. It is currently the only way to root the phone. The Clockwork recovery method that is posted above is not for L45C, it is for P698 and P690, which can brick your phone trying to install it in a phone that may not support it.
Also, good luck with getting software updates for the phone, because Net10 WILL NOT let you upgrade the software on it. It will download the software package, but states that it is invalid and will not install it. If they would allow the phone to update itself, it wouldn't have many bugs that are showing up

Guys I tried the method mentioned above for adobe flash but the files that I place inside data/data/com.adobe.flashplayer/lib keep getting erased everytime I restart my phone. Note that flash works perfectly as long as I dont restart my phone.

Sorry but that's how it is. Try using cm7 it doesn't seem to disappear.

I'm getting failed to chmod file: rootutility

While doing what -rooting or custom recovery?

rooting. with unlockroot.exe. Superoneclick fails as well

You've asked this on androidforum as well so i'll try to help you there as akashash5 but I think andyopie will give you a solution eventually.

Using Qtadb P690F> PC
Just one addition, as I had problems in using Terminal Emulator on my small screen phone, I wished to use Qtadb which is able to be run from a PC under Windows. I had all sorts of problems getting Qtadb to 'see' my phone and the installed files.
This is what I had to do:
1. Download and install Qtadb and Windows binaries Google as can't post link
2. Download & install LG drivers
3. DL & install Busybox Google Play
The last item was my problem, I had seen this on one of the many threads I checked & had DL but had NOT installed. When installed all problems solved.
Hope this helps someone.

you wouldnt happen to have the link for the lgl45c cwm would you?

Sorry but I don't think there is a cwm made for l45c

Hi long time phone community forum member but this my first post:
I spent multiple-hour long sessions looking for info on this stupid cute lil phone that my girls kid liked. and i was so shocked that first off i couldnt get this rooted with oneclick or a zergrush attack, then after rooting that there is little to no dev for this phone.
if you want to root it use unlockroot.com (i agree that this tool looks funny and like its going to be an advertisment or scam, but it worked)
for custom cwm recovery i used cmw v5.0.2.7 for the optimus q(lgl55c) this worked in the lgl45c that ive got i will not guarantee that it will in yours but if i was you id jsut go for it. I obtained it here:
androidarea51.com/***-all-things-root-***-12/custom-cwm-recovery-for-the-q/
---thanks to Mark_One (im guessing of that site) for the files adn info---
on that same page is the flash_image.zip file that you unzip to the root of your sd card and follow the instructions to flash the recovery into your phone. I used adb shell instead of terminal editor and used esfileexplorer.apk to move some files adn grant permissions where adbd wasnt cooperating
I put a pretty fun rom thats from the androidarea51 site into teh phone its some redrom adn is all devilish with red icons and widgets adn screams redrom redrom like redrum redrum on bootanimation this was also for the lgl55c so after i flashed it i did adn advance restore and only restored teh boot from my initial backup.
i am having a hell of a time getting this into a diagnostic mode?? lgs usually dont need to do anything just enable debugging. ive done this i get an lg androidnet modem adn two ports, they appear in qpst but are not listed with an active phone?? can anyone help me with this also spent hours looking for this, im wanting to flash it to cricket and need to change the prl.
hope this is helpful and reduces some peoples searchings for the optimus net lgl45c

Good work, just keep upgrading the list.:good:

I dont have the link, but you can find it at androidarea51 on the OptimusQ thread (lg l55c). It worked on mine. I just followed the directions exactly. Good luck, hope it helps.
Does anyone know where to find a link to a stock or rooted rom for this phone? Mine is rooted and has CWR 5.0.2.7, but is stuck in recovery bootloop. (loaned it to my daughters friend to play games on while i fixed his, he thought he could reset his game when he found settings, factory reset). If anyone could help i would appreciate it, or if anyone knows another way to get this to boot to phone i can go from there. thanks in advance, you guys on XDA are great.

What have you flashed the phone to get a boot loop?
And a warning, when you actually had a Cwm on your phone and you factory reset it, your phone will be bricked.

This looks really rough, but apparantly there is a boot.img, then other cracking tools can be used.
I'd love to try it, but... well... my chinese is limited to google-translate.
The URL won't post so this is a big hint:

Currently on that URL is a approx 14 MB rar file download, I _think_ I just got it sorted!
I don't have time now to make this pretty, but some others who want to hack. add links, etc feel free to work with this...
in fact I dont know if all these steps are required.
General Broad steps (ymmv, you are doing this to your own dang phone, dont blame me for bricks viruses or earthquakes etc, etc/ etc).
on your computer, uninstall adb, pdanet and any other tools that use the adb drivers and dlls, reboot as needed.
install the mt6575 drivers (I forgot whether I downloaded these or if they were part of the 14 meg file) reboot as needed
power down phone.
remove battery from phone, don't plug into computer.
launch flash_tool.exe
load the included scatterloading file MT6575...emmc.txt
press the download button
plug in phone to usb
put battery in phone
watch the blinkinlights for a few seconds, wait for the big green O
then I disconnect phone and ensure power down.
install SDK
power up phone and plug in
test adb (adb shell)
kill adb server
download and install superoneclick
download extra superoneclick exploits
launch superoneclick
click the big root button.
Test (you can use something like rom manager)
Now people should be able to try to install various CWMs.
I haven't gotten that far yet.

Great work!!! I'll try this on my phone or wait until is working?
Are the recovery and rom in chinese?
Thank a lot for testing.

It is working very well.
No need for you or anyone to wait.
Just please know what you are doing (do you have basic understanding of recovery mode, roms, factory mode, and the dangers) in other words, if this is your first time doing this on a phone.. ask someone who knows what they are doing for help because I am not able to put together a documented procedure, but the findings above should allow someone else to do that. Additionally, I have no idea of the legality or safety of the software at URLs above.
conceptually this is 4 steps
1) flash boot.img that will allow cracking
2) crack to get SU installed
3) install Mobile Uncle Recovery mode and app
4) install gapps.
The MobileUncle recovery mode is Chinese, But the mobileuncle app is kinda like rom manager, it lets you set up what happens at next boot so you don't need to read the chinese in recovery text mode.
The patched rom is working for me in English with root, no detectable problem except FC on google partners (and I can't tell if that actually does anything). Remember this is not a new rom, just a patch to the huawei rom that allows a root crack.
There are about 4 chinese apps that I am afraid to uninstall..
one appears to be a chinese app store too, kinda fun to browse
gapps must be flashed with mobileuncle recovery (don't just unzip them)
US google play store is working.
I am fully migrated to this phone now and use it for daily work.
Good luck, and remember that this is why you got an android instead of a i-Thing.

Thanks thanks again. I'll try it and don't worry this is not the first time to modify a mobile. If it is all ok i posted here.

Working u8812d
Ok... It was successfully working on my phone. I have root and change recovery and then installing gapps. Almost of the apps is working of the play store. Thanks again and hope there is a release of ICS or JB rom for our phones.
See ya!!!:good:

Thanks for the steps though the problems are still coming thick and fast, I have a new U8812D from China, no China unicom splashscreen but lots of 'bloatware' still. I've been trying for days to root this thing and nothing's working.
I'm pretty sure I need root access becasue the phone is currently preventing me from adding my Gmail account and using the google play market and apps, other bits and pieces like assigning incoming call number to a contact are supposedly fixed by getting the google thing right. The phone is good but I'm missing alot of functionality.
If the above description sounds like rooting is not the solution, please let me know and point me to the right forum, if rooting is the obviously the only way out, I'm hoping to clarify a few step in the above walkthrough to help me and others.
1. I cant install the mt6575 MediaTek drivers, installing directly gives error 'driver cannot be installed this way' there is no COM-LPT port in my device manager to attach it to as a manually locate driver, I can add a COM port with add remove hardware but I have Code 10 error, device cannot start and doesnt seem to accept the mt6575 driver as an update even when forced to it with locate new driver, apparently this is no problem from other forums, still bugging me. Maybe I havent the right files? how do i get COM-LPT ports to show up properly?
2. when 'install m6575 drivers ... reboot' is the phone plugged in? to what device do we install the drivers or should it be automatic?
3. launch flash tool, i have located two versions of the MT6575...emmc.txt file, one delivers error, block count fail and has no files paths for the item in the main table, the other refuses to open, giving error, incorrect scatter file format. The latter has considerably more data in it when read in notepad.
4. Becasue of these errors, SP flash tool does not download to phone. all subsequent steps fail.
Assuming the initial flashing steps are successful, I must to use SuperOneClick to root the phone, where do I find the extra exploits needed? or are tehy automoatically sourced by SOC? Succeeding the root access step, I assume i can freeze the apps causing problems to my google sign in or delete them. Or could I please be directed to the ATTPlain rom mentionned by JohnnyParanoia in 'Almost All Huawei Stock Roms (Firmware) - Updated 28/06/12' board.
Since so many of the resource files I've trawled through are bung, anyone who can point me to reliable/tested files known to work with the U8812d I'd greatly appreciate in on top of the great appreciation I already have for your patience with a Noob. I located the 14Mbit .rar file mentioned above but not all parts worked, had to dl the different programs individually and some files had to hunt down form fileshare sites.
Lastly, i am using an HP laptop, Windows 7 64-bit, Thanks in advance.

[GUIDE]How to flash LG ICS KDZ and root it!

As of 28/12/2013, I no longer have this phone. My threads will stay open for all who want to assist others. I've had a great time being a member of the O3D community, so thank you all!
For questions, requests or any other remarks, please don't send me PM, I will not answer. Instead, please post properly in the thread, so that anybody can read and benefit or even assist.
Using the LG Flashtool has never been to my liking. So, as soon as I read about the new ICS for P920, I dug up my hard drive for that nice little tool that had beautifully served me back in the ghost-calls days to easily flash back and forth Froyo and Gingerbread! After successfully upgrading once more, this time to ICS, I decided to write this guide.
DISCLAIMER: This procedure is NOT for the faint hearted! If something goes wrong and you fry your device, I cannot be held responsible. Hundreds of people have successfully upgraded (or downgraded) their devices using this guide. If something doesn't work for you then you're doing something wrong! Read the guide again and find what you've been missing.
I'm always open to suggestions. So, if you feel like I should have described some part in a different way, please say so. Of course, this means that from time to time, as new suggestions come in, I will edit parts of the guide to make it as helpful and understandable as possible. So, if you are planning to flash, stay tuned for the latest info.
Links to KDZ files
- Leaked EURO beta P920V28B_00.kdz (rename it to V28B_00.kdz)
- EURO OPEN V30A_00.kdz
- SPAIN Vfone V30B_00.kdz
- You can actually use any KDZ firmware for the P920
Flashing Part 1 (What you need):
A. Download and install LGUnitedMobileDriver attached at the end of this post.
B. Download and unzip KDZ_Flashing_Software.zip attached at the end of this post.
C. From the folder you just unzipped, install LG Mobile Support Tool (B2CAppsetup.exe). Quit the application after installation has completed.
D. Right-click on msxml 4.0 SP3 parser.msi and select Install.
E. BACKUP your data including the contents of your internal SD to your PC, especially if you're upgrading from ported SU760 ROM, cause it may be erased!!!
F. (Win7+ users only) Open the properties of the UpTestEX.exe and Windows Enabler.exe, enable XPSP3 compatibility mode and Admin rights and click OK.
Flashing Part 2 (Procedure):
1. Run "Windows Enabler.exe" and turn it on by clicking on its taskbar icon.
2. From the folder you unzipped previously, run UpTestEX.exe and select 3GQCT and CS_EMERGENCY
3. Select the KDZ file you want to flash.
4. Put your phone in S/W download mode
... To do this, you need to shutdown phone and connect USB. To make sure phone is off, press power for about 10sec. While keeping Vol-Up pressed, press power for about 3sec. After you hear the USB connection sound on the PC, you may release Vol-Up. (Depending on your bootloader, you may see the Korean S/W screen, or your screen may remain black). If this is the first time, let the PC install drivers.
5. Now click on "Normal web upgrade test" (don't click on "Start Upgrade").
6. In the new window that opens, click on "Upgrade Start".
7. Select "Different Country" and your preferred language and hit "OK".
8. Flashing has now started. Wait until you see the following...
Code:
...
...
14:37:21 : CDMA: wParam = 2004, lParam = 99
14:37:21 : Model Dll Msg Not Found(2004, 99)
14:37:23 : CDMA: wParam = 2004, lParam = 100
14:37:23 : Model Dll Msg Not Found(2004, 100)
14:37:23 : CDMA: wParam = 2001, lParam = 0
14:37:23 : Model Dll Msg Not Found(2001, 0)
(It is normal to hear the USB disconnection sound before flashing is finished. DO NOT INTERRUPT before you see the above log!)
Wait until the updater has finished.
9. Exit the tool and remove USB cable.
10. Power on the phone to see that everything works.
Factory Reset
It is not necessary but advisable to do a Factory Reset at this point, so make sure you have made a copy the contents of your Internal SD to your computer and go to System Settings/Backup & reset/Factory data reset. Select "Erase Internal Memory" and press "Reset phone".
IMPORTANT: Do not try to do the factory reset as described above after you have flashed a custom recovery. You may end up in a "recovery loop"! Instead, you can boot into your custom recovery and do the reset from there!
How to root:
There are three methods that I know of. You are free to select the one that suits you best, but Baidu is my personal favourite and can be used on other devices too.
BAIDU EASY ROOT APK (any ROM - Easiest way)
Make sure you have USB Debugging and Unknown Sources enabled.
Turn off all Internet communications (mobile data and WiFi).
Attached at the end of this post you will find the app. Just install it as a normal apk and run it. If you forgot to turn off Internet, it will ask you to upgrade. Don't let it, because the newer version will be in Chinese! Sometimes, the app may exit after you refuse to update, so be quick to hit the "root'' button before it asks.
In about a minute you will have root access. I would then recommend you to go to PlayStore and install SuperSu, run it and let it replace the su binary.
After that, you can uninstall Baidu root.
VROOT ON PC (ICS only)
Read this excellent guide by OptimusRS
FLASHABLE ZIP (any ROM)
1. Download Su_Bbox_1.20.2_gazhead_signed.zip and save it somewhere in your SD card
2. Use OS_Hacking's tool to install Wkpark's v1.25a ICS bootloader (read here if you need more help with the tool). After this step, your boot-up LG logo will be silver!
3. With the same tool install a GB recovery. (ICS recoveries are only for xbsall's ported SU760 ROM, they can't read your internal SD - Read here for an in-depth analysis)
4. Boot into recovery
5. Flash the zip from step (1) and reboot. Check your apps drawer, you should now have Superuser app.
6(optional). Now that you have root access, if you want, you can restore the Stock Bootloaders and Recovery (you can't have a custom kernel with stock bootloader). Download Stock_ICS_btldr-recov.zip (attached to this post). Reboot to recovery and flash it. Reboot. Now you have a rooted ICS with stock bootloaders and stock recovery!
Additional reading about bootloaders and recoveries. This is important info. If you understand it, you will avoid lots of problems when flashing.
Troubleshooting:
1. If you shutdown your phone from the power menu, it will turn back on by itself. This is a bug in Wkpark's 1.25a bootloader. If you want to completely shut your phone, just keep power pressed for about 10sec as soon as it starts to reboot.
2. To boot to recovery, Shut your phone down as described above. Keep Vol-down pressed and press Power for about 4sec. Release Vol-down when you see the silver LG logo. If this doesn't work, there is also another way. Again shut your phone completely. Keep Vol-down + 3D pressed and press Power for about 4sec. You will see a menu with three options. The last one will be -Recovery and it will be preselected. Release keys. In a few sec the phone will reboot to recovery. Remember that the O3D is quite stubborn and may not boot to recovery every time. Keep trying and it will work eventually!
3. I mentioned above the possibility to get into a recovery loop (your phone boots only to recovery). I have made a flashable zip to break this loop and boot back to android. Just download P920_ICS_RecoveryLoop_Breaker.zip (attached at the end of this post) to your computer. While your phone is in recovery, connect it via USB, select to mount SD to computer and copy the zip. Eject from computer and flash the zip. Reboot. After booting into system, you'll have to flash a new recovery (e.g. from ROM Manager or OS_Hacking's Tool).
4. Losing IMEI is something that doesn't normally happen when flashing KDZ files. It happens sometimes when flashing BIN/FLS. I suspect that flashing a KDZ with this guide after you have lost your IMEI will actually fix it! This remains to be proven (feedback please). Another way that has been confirmed to work is to run LG Mobile Support Tool, connect your phone in S/W download mode and select "Recovery Phone" from the "Customer Support" menu. A popup will appear asking for the IMEI. You need to type the correct one (it's written beneath the battery). The tool will then download and flash the latest official firmware for your country/provider fixing IMEI at the same time.

Agree that LG Flashtool is a joke. However, smartflash is great if you aren't doing a baseband.

This ROM has all 3D features?
Tks so much!

Yes!

The LG Flash Tool is not so bad for all of us who are used to it because we had to downgrade/upgrade ROMs during that dreadful ghost-calls era.
And according to many reports here, the LG Flash Tool /kdz method, is the most reliable when flashing the new v28b ICS rom.
I'm still not sure about the step 3 though and flashing a GB recovery instead of a ICS one, like many people did already. It may be that the "recovery loops" are cause by the bootloaders and not the ICS recoveries but this has to be confirmed.

I think you may need to replace the KDZ file name as V28B_00.KDZ.

Do i need to install wkparks boot loader if i don't want to root the phone?
And does the IMEI Change after flashing v28 via kdz?

Hi,
i've tried your guide step by step. But i'm stuck at the part 6, i'm waiting nearly 30 min with an "MOD UpTestEX MFC Application doesn't work" (translated by me) messagebox and at the taskmanager the memory usage doesn't change since the messagebox. Only the phone heats a little bit.
I have done this twice. Second try after a clean reboot and start as admin but this doesn't help.
After this the phone is unchanged.
Any advice ?

Perhaps it doesn't work with the updated drivers. Google for "LGUnitedMobileDriver_S4981MAN32AP22_ML_WHQL_Ver_3. 2.1", uninstall your drivers and install these. I will try to upload later when I get home.
Edited 1st post just to be sure.

Very good manual. 10x for the work. :good:
is there any reason to be GB? I have installed ICS CWM touch with the same tool and still work.

It's because we are now using the standard P920 (GB) partition table again, so ICS recoveries won't read your Internal SD Card!

I've downgraded but it doesn't change his behavior. Could the OS (win7 64bit) be the problem ? I found old guides where they use XP.

OK! Sorry for the trouble. I will update 1st post! I guess you have to find an XP machine or use a virtual machine or simply use LG Flashtool! You may also use Smartflash for the system (bin), but not for the baseband (fls).

[Q] Batch file won't open

Hi All, new to forums. No one else seems to have had this problem, or am I trying to open it wrong? I try to d-click the batch file runme.bat to get root access but it won't open as the message says it's not supported on LG-Optimus L7II dual running Android 4.1.2. It opens in Win 7 so it proves that the file is OK. Hope I get some info on this, thanks.

Hello,
.bat files are Windows/DOS batch scripts that does not (generally) work on Android.
Most likely you have to run that .bat file on the Windows computer with your phone connected.

Thanks heaps Cyrus_pc, Had to use Cydia Impactor a few times to reroot, worked perfectly. It gained root but Root Checker from Jacksoft labs
said no root. So did search on xda forums (can't Remember thread to thank them) and used terminal to type SU and check root(thanks). Also, used Root Checker by joeykrim and that does work.
If I can indulge a bit about other problems with my phone model LG Optimus L7 II Duo P716, this may help others. I first wanted root access to use Titanium Backup and Rom Manager before using LG update to see what was new and roll back if needed. Bad move, Rom Manager wouldn't backup or boot to recovery mode just kept Factory resetting and loosing settings(what a pain).
Fix this from xda thread from Blackzair with (CWM Recovery on LG P&15 L7 II Dual) boothack+recovery.rar to load Gscript.apk. Got into recovery even though as he said screen is upside down.Tried to load a CM 10 but it didn't take, will have to check boot image version.
Thanks again to everyone
