Now you just download a rom (.zip) and put the zip on your memory card, boot in to clock work, and go to install zip from sd, choose zip, then locate where you placed the rom (.zip file), and yes to install.
After that simply reboot your phone, wait a bit, and your phone will work.

go to google in search box type in cyanogenmod mirror select your phone model download desired rom to sd card and in clockwork mod select install zip from sd select file and and your good to go any / just inbox

thanks so much guys it works great now

[Q] cant access rom manager on boot to update cm9 nightly

Hi all
I am stuck on an older cm9 nightly from March and desperately want to flash the newer cm9 released a couple of days ago
My problem is that I cant boot into recovery, rom manager doesnt work and the various other apps that I have found people recommending dont work either.
Could some kind soul tell me how to get rom manager back to working order so I can reboot to recovery so I can install the latest nightly? Or suggest another/better way to go?
Thanks in advance!

Try turning off your Tf, and holding the Volume-Down key Before and While you hold the power key to turn it back on. This should boot to your cwm recovery if you have one, if it gives you nothing or the stock recovery download the Recovery Installer.apk in the development section and (You MUST have root, I assume yes on cm9) open it and flash 3.2.0.1 cwm recovery. Once that's done you can flash the newest nightly. Keep in mind that 3.2.0.1 ONLY reads from External SD card (MicroSD) so be sure to get one or NVflash a newer recovery with internal.
Also a tip: Rom manager has had a host of problems for the Transformer, and while it's really good for some supported phones, it's not so good for the tf (just look around Q+A and the dev you see all sorts of ROM manager related problems)
Good luck

Recovery installer apk is actually in apps n themes section. And it read both internal SDcard and the microSd as well.

Actually if you use Gnufabio's version it will flash Roach's CWM 3.2.0.1
It only read from external micro sd card.
There's a modified version of RecoveryInstaller that flash Team Rouge's recovery, that version read from internal and external sd.

After you have install recovery do the manual button method as posted above by Thing O Doom
or use this app
https://play.google.com/store/apps/...sMSwxLDEsImNvbS50cmFuc2Zvcm1lci5yZWNvdmVyeSJd
It's highly recommended you know the manual button method for when you're in a bootloop or your TF is stuck at the Asus page.

Resolved
Excellent, thanks so much for the help all, ended up getting team rogue's recovery....I had tried Gnufabio's one before and it hadnt worked when I installed and used the power & Vol down button(as the recovery image would not boot ever and froze after the first nightly I had installed)
Just a word of warning on the 4ext boot to recovery option, and this could just be me with Rom manager on previously when I tried to fix myself, when I installed 4ext it would freeze on boot totally...only way I got it to work was cold booting linux so just so you know it does seem to have its problems too
But I am now downloading the latest nightly to flash
Cheers!

Soft Brick CM9 bootloop- CWM 5.8.4.3 semifail

Currently I am in a soft brick state- I cant remember which CM- 9 either cm-9-20120614-EXPERIMENTAL-skyrocket-alpha5.zip, or cm-9-20120709-NIGHTLY... (I can see that those are the only two I have on my sd card. I am on an ATT GS2 skyrocket
If I boot normally - it stays stuck on the CM9boot screen.
I can use the 3 finger method to boot into CWM 5.8.4.3
While searching for answers I read that this CWM is broken.
Initially I was trying to go back to an earlier recovery. CWM would see the recoveries on the SDcard, but when I tried to recover- it would not mount from the SD card.
I got to CM( by using odin to put an earlier CWM, and superuser on the phone, then installed Rom manager, then used rom manager to flash CWM (via tmobile sgs2) then updated to CWM touch...
When I tried using the CWM to factory restore and cache wipe it starts then hangs I cant install zips from the external SD card, or any recoveries...
I'm figuring worst case - I can go back to ODIN, and do stock recovery http://forum.xda-developers.com/showthread.php?t=1342348 , then flash the non touch CWM, superuser http://forum.xda-developers.com/showthread.php?t=1340526, then flash a recovery from my sd card??
Is there something else I might have missed in trying to get back to a functional state without going to odin?
Many thanks in advance for any assistance

Hi there,
I recently experienced the same thing, and it was a hassle to fix--but I have got my phone working each time. The downside being that I /had/ to switch over to Odin. Mind you, I am not necessarily experienced with Android, so I can't really say that this is the only way.
At any rate, here's what I did to get it back to normal:
Load up Odin
Put it in download mode -- I assume you know to hold the volume keys and then plug in the USB.
Flash either the ICS leak or the stock 2.3.5 Gingerbread.
You should be back to good. I hope you backed everything up in either Kies or some other resource...else you're in for a hell of a time setting stuff up.
Oh: bad news about the 2.3.5 stock is that, as far as I can tell, you're unable to upgrade to 2.3.6. In turn, you're then unable to update to the official ICS through Kies or OTA. I assume you don't mind, considering you're trying to flash a new rom anyway.
Anyway, I do hope there is some bit of clarity on getting CM9 on the Skyrocket. As of now I have still been unable to do it. Just as you, no matter the settings I try, I end up being stuck at that screen. The only difference between your method and mine is that I completely did mine through CWM...nothing through ROM Manager. (Actually, I believe I tried a few differing methods involving the CWM touch and non-touch...followed many different guides but still no good.)
Hope you get it back to a functioning state. If you get CM9 working on the Skyrocket, I'd appreciate you sending a bit of details on how to do so.
EDIT: I am now on CM9. Through magic, ponies and friendship I have failed to accomplish this feat. But by pure science and the blood of a pony, I have successfully installed CM9.
After you've restored to 2.3.5 or the ICS leak (the one I was on), do the following:
- Grab the recovery-clockwork-touch U27 described below. Flash it.
- Download both the newest CM9 build from their website, as well as Google Apps, and then copy those to your external SD.
- Follow this guide: http://www.teamchopsticks.org/p/install-guide.html. Here's what's relevant to you:
Wipe data/factory reset.
Format /system (mounts and storage->format /system).
Install the CM9 zip from SD card.
Install the gapps zip from SD card.
ONLY IF YOU ARE ON TOUCH CWM RECOVERY: Format /cache (mounts and storage->format /cache)
Reboot. Let it sit for a few minutes after the first boot. Be patient.\

After ~10 minutes you should be fine. Mine took less, but I'd bet it could take longer. Please follow those directions above EXACTLY. I'll be happy to help you in any way I can if you reply to this thread/ send me a PM.

When I softbricked with the latest CWM I wasn't able to return back since it wouldnt detect my SDcard so I just loaded up odin and used recovery-clockwork-touch-5.8.1.3-hercules.tar and was able to read my SDcard again which had all my backups and CM9 files. I have flashed every version of CM9 every since and still using this CWM version and havent had any problems. :good:

All better now- I used ODIN to restore to stock, then used it again to put CWM (non-touch) back on, then added superuser, then just did a restore from SDcard! Muchas Gracias all!
Should I be able to then use a restore of when I had a working CM9 (and backed up with CWM)? Or would I have to do all the cache wiping/ factory reset like I did to install it the first time before using such a recovery? (and I will try that recovery- clockwork touch hercules... latrer tonight from home)

ODIN tar to restore back to factory. I got the boot loop too. Only until after I flashed CM9 then flashed dark side wipe cache only would CM9 work for me. Only on regular CWM though. Try and give that a go.

problem after upgrade BaseBand

Hi
I have LG OPTIMUS P500H
I installed CM7 + Kernel. after that installation i couln't talk with the phone (NO SERVICE). so i installes new BaseBand the V20G and the service is back.
THE PROBLEM IS:
1) No 3G and NO WIFI.
2) After the CM7+Kernel installation the ClockWorkModRecovery version was 5.0... But after the BB upgrade the ClockWorkModRecovery version was 3.1.0.0 and it's stuck and i can't do recovery.
3) In the phone menu ther is an option to install from sd card but there is a message that there is nothing on the sd card. but when i connect the phone via usb i can see all the apps that on the sd card.
NEED HELP

1) Try to reflash your recovery through ROM Manager and choose "new BB".
2) After you flashed CWM through ROM Manager try to reflash CM7 too, but back up your data first.
Did you install a custom kernel on CM7?
Also what do you mean by "i can't do recovery"? If you can't enter in the recovery mode or you can not install anything the only solution is the one above. Also pay attention that recoveries can install ONLY ZIP ARCHIVES, not other types of files.

Hi
1) I installed that KERNEL (2.6.35.14)] candiedIce v2.5.6 (2012-08-29) and the CM7-20120902-NIGHTLY-p500.zip
. after the BB upgrade, it's look's like the CM7 deleted beacause the phone back to it's first homescreen, the rom manager + the superuser deleted.
after that the phone info is:
android ver: 2.3.3
kernel ver: 2.6.35.10
build number: GRI40
softwer ver: LG P500 V20G
2) I can get to the CWM (power + vol+ home) and i can see the menu but it didn't respond it's stuck.

I tried to flash but i get a message that's said: "An error occured while attempting to run privileged commands!".
And when i tried to ROOT again with GINGERBREAK it's stuck. (run almost an hour and i stopped it)aginnors vere-

Lolz.. instead of upgrading baseband.. you flashed stock GB rom.
Your root is broken.. did you root using superoneclick?? Gingerbreak wont work in GB 2.3.3.
Use oneclick again and root it again. After that flash CWM 5.0.2.0 using Rom Manager.
Then do usual things to flash rom.. kernels.. etc!!

Hi
I used GingerBreak, and i already upgrade the BB, I cant found SuperOneClick all the link's is broken.
Is there anything to Reboot again.

Hi
I succeed to Root with SuperOneClick v2.3.3, but i can't to install the CM7 because the CMW is stuck.
Is there something thats i can do to delete or reinstall the CMW.

Install rom manager and flash clockworkmod from it
Sent from my LG-P500 using xda app-developers app

If you are on new baseband.. reflash cwm 5.0.2.0 through rom manager.
Select new bb when the flash option comes!!

Booting with booti: mmcread

Hello!
I've got a problem. I flashed PACMAN rom from berni witho Gapps and...
All works fine. But when I try turn on my phone I've got booti:mmcread0... I don;t remember.
What can I do? After this mmcread... screen becomes many colours.
What should I do? I'm coming from 28b normal rooted with CWM recovery.

Come one man.. stop this smartflash ideas. and bootv21e.
first smartflash give you many problems asi IMEI lost, then you go back to GB with this 21e.
So... now to Karim Kahale
Explain us what you had before PACMAN
1. Bootloaders?
2. Recovery?
3. GB or ICS?
4. was this mod ROM or stock?
5. How did you flash it? Did you clean any thing. Did you read all on the first page?
6. Is this PACMAN on dual boot or not?
Then we can start thinking about that.
some ides
- if you had stock ICS before with locked bootloader - probably the kernel has to be changed
- if you had GB - look the first page
- go to recovery and flash another Rom if you have - before that keep the power button for 20 sec to be sure that you stop the phone, and then start it for recovery.
.
But do not use SmartFlash.., if you go for such a big system change... let use LG Flash Tool and use 28b big partition.
edit: someone with the same problem like you link

The Fact You see booti:mmcread0 (AFAIK Stock loader does not display anything~) means you wkparkbootloader but which version if not 1.25a flash it then reflash the rom i also got that with a previous version of pacman just reflash your rom or try another think it has something todo with the kernel

Before PACMAN I had the same problem with MIUI by OptimusRS. But I couldn't enter recovery mode. Then, when I boot in recovery, i couldn't boot phone in normal mode! Flashing with CWM didn't work.
Then I flashed normal v28b (without fls file, only bin) with normal partitions from xbsall. Than i flashed bootloader and CWM using All-In-One by OS-hacking version 1.2 (in the first post of this tool there is an information "6- ICS Bootloaders (wkpark's 1.25a Bootloaders)"
PACMAN I downloaded from there and read all on the first page.
Version pac_p920-nightly-20130613 but I couldn't flash it because when I tried it in CWM was: assert fail Status 7 instalation aborted so I delete updater script assert and then flashed rom and gapps. Before flashing I did "wipe data/factory reset" and "wipe cache". Anything more.
Then I wrote this thread. I boot in recovery mode (to see does it work) and now I can't boot normal. Only CWM mode. Flashing rom with CWM doesn't help. That same as it was with MIUI. What should I do now? If I flash 28b with flashtool what should I do next?

probably you are in recovery "Recovery Loop". take the file of the fires post form this threat. Then you flash new recovery.
And read the whole first post there. hope this work for you

Thank you bro! I'll try this today. Now I am on another computer but second is in my neighborhood. There I have all needed files. Today I'll edit this post and tell you does it work.
EDIT:
I've got a problem :/ When I try: mounts and storage>mount USB storage it doesn't work. I can't mount sdcard because my sd card reader is damaged. Why? I don't know.
When I replaced my digitizer in phone reader stopped working. Before it works. I was on ported acura (korean based on port from xbsall). After that I flashed v21e Gingerbread and reader didn't work.
What can I do? I want use my sdcard but I can't.
EDIT 2:
I couldn't copy file to phone so I flashed v28b normal partitions by xbsall. Please tell me, what should I do now? I don't wanna flash next time with LG Flashtool.

Do you want ICS or JB?
In both cases you should do that:
1. Download this tool. Probably you have it already.
2. Flash with it EXACTLY:
(8- Flash ICS BootLoader)
(6- Flash TWRP Recovery (version 2.3). - Yes... this one. not the one for ICS.
3. Start the 28b that you have and format both internal and external card - make a copy before that
4. Reboot in recovery and install the custom Rom according to the instruction
Unfortunately you install the normal partition so many roms will not work. I suggest you that you install the big partition 28b. with it all roms work.

OK. I'll try it. But why my sd card reader is damaged?
Do you know how can it damage?
EDIT:
What do you think? Phone will work better with ICS or with JB?
Which one is better?
I don't need 3D, but smooth. Only smooth and fast.
And should I install v28blarge only bin or bin + fls?

JB Kernels are still not mature for O3D. And there is where you get more battery and speed. Look in my signature what I use. For me is the best combo. if you delete around 40 apps that you do not use form Darkroom V4 XXL ROM and put Acura Next Level V4 KERNEL and tune it good - you can get around 2-3 days using your phone in light condition. I could not get more than 24h with any JB and tunings.
Edit: only the BIN. take the fls form 30a

Thank you one more time. What do you think about this rom?
And:
How can my sd card reader damage? Is this problem of system or hardware problem? When I was on ported ICS I didn't flash bootv21e. At once I flashed normal v21e. Maybe it's the problem?

it is not damaged. probably you have to re-format it within the system you use. search around the forum - i do not have in mind in the moment. Was s.t. about ported ICS and P920 ICS file system.
OptimusRs is a good developer. I have not test his rom but is based on 30A so probably is OK for you if you are from Europa.

have you search around the forum? have you try to format the card on your phone or computer?
with this tool you con format your card (on the computer not inside your phone) to be Fat32 - just delete the partition and make a new one in fat32. put it back in the phone and try again.

I'll try it. But problem is the any sd cards don't work on phone but on other phones it works.

I have just format my sd card and the phone doesn't detect it. What's happened?

Can someone help?

I think this has basically been said before, by defcomg and others, but it could be from a bad flash due to incorrect driver install or incomplete flash. Yes, you will need to use LG Flash Tool to reflash. Follow 1-2 here,
http://forum.xda-developers.com/showthread.php?p=39269819
then install whatever rom you wish. Just be aware that some custom roms require wkpark bootloader to be installed first, as has been said before.
I have not tried installing Pacman.

Sorry that I haven't replied. I was in Italy ;D
So, if i flash it, will sd card reader work?

If it was working before, it should. Mine is working. I have heard of this issue before with Pacman; I think it is a bug with some versions of it, but don't quote me on that. There is probably some other way to fix it, but flashing a ROM known to work is one way.
