[TUTORIAL] Fool-proof method to install latest CM7/MIUI without losing Baseband/IMEI

Lets get this out of the way first. I am not responsible if you screw up your phone, but you are probably here because you already screwed up your phone. I have now been through this several times over the last few days. Some will say this process is overkill, but there is no denying that it always works, so please refrain from stating the obvious.
If you have installed or updated CM7/MIUI and lost your baseband, IMEI, or both, this should help you. Due to the amount of people currently having this problem, I would recommend this be stickied at least temporarily until things are straightened out, so people can find it easily.
For Windows only, I do not have a Mac.
Step 1 - Read the entire post and understand everything involved before you attempt this. This is a long ride, probably 30-40 minutes from start to end. This is not for new people, and will assume you have a certain amount of knowledge because you attempted to flash CM7/MIUI.
DO NOT SKIP OR SHORTCUT ANY STEP IN THIS PROCESS, UNLESS I SPECIFICALLY STATED YOU MET THE CRITERIA TO DO SO. DO NOT EVEN THINK ABOUT TRYING THIS UNLESS YOU CAN REACH DOWNLOAD MODE AND RECOVERY USING BUTTONS WITH THE PHONE OFF!
Step 2 - Gather what you need...
1 - The AIO Vibrant Toolbox : http://forum.xda-developers.com/showthread.php?t=954509
Install according to directions in the post. Donate to this guy. He spent alot of time making this easy for you to do.
2 - The old CM7 install files : http://www.mediafire.com/?gn4qoonoe3cjyp6
Unzip to a location that is easy to get to.
3 - The new version of CM7/MIUI you want to install, from the thread of your choice. Donate to the developer you are using, they spend alot of their free time making your phone better. They don't get paid for it, and they dont charge you for it.
4 - Your phone, with a full battery.
Step 3 - Odin to JFD and install Clockwork 2.x
1 - Fire up the AIO Toolbox. Do not connect your phone yet, but power it down and pull your battery. See that sticker under it that says IMEI? Write it down! You will be referencing it a few times throughout the process. Start Odin and select your pit and pda files, they should automatically come up if you are using the toolbox. Hold down your volume up and down buttons, and insert your USB cable, then insert your battery. You should go to download mode, and see Odin connect. Hit start and let it fly. Once it reboots, unplug your phone. Go to settings/about phone and you should have a JFD baseband. Hit status, and check your IMEI. See how it matches the one you wrote down? Yay! Move on to the next item. If it does not, you have some reading to do because you really screwed something up, and it is beyond my power to help you...
2 - Mount phone and put the following files on the root of the sd card:
vibrant-efsbackup.zip (if you already have a backup/efs folder on your sd card you do not need this)
cm7-vibrant-initial-20110224.zip
The zip file of the new CM7/MIUI rom you want to flash.
3 - Download ROM Manager and install clockwork recovery 2.x (if you already have the update.zip on your sd card, which you should, you can also skip this) and power down your phone.
4 - Boot into recovery using the 3 button method (holding volume up and down and power, releasing power when the word VIbrant appears on your screen), hit reinstall packages, you may have to hit it twice to get to clockwork recovery. Choose to install zip from sd card, and select vibrant-efsbackup.zip. Let it do its thing. Then select reboot, and when it does, check your sd card for a backup/efs folder. Got it? Good. Power down the phone. (Obviously, if you already have the efs backup completed, you could have skipped this step.)
Step 4 - Install Clockwork 3.x and Old CM7
1 - Fire up the AIO Toolbox. Do not connect your phone yet, but pull your battery. Start Odin and hit the pda button, select the file cm7-vibrant-initial-kernel.tar from the CM7 package you unzipped (Remember, in a place that is easy to find). THIS IS IMPORTANT - UNCHECK AUTO REBOOT!!! Hold down your volume up and down buttons, and insert your USB cable, then insert your battery. You should enter download mode, and see Odin connect. Hit start and let it fly. Once it is finished, pull the usb cable. With the download mode screen still on your phone, boot into recovery using the 3 button method. You should now be in clockwork recovery 3.x. Move on to the next item! If you did not get in, you can try to pull your battery, replace it and boot into recovery from there. If you still can't get there, you get to go where the people who do not properly follow instructions go... back to Step 1.
2 - In clockwork 3.x, choose factory reset, and let it do it's thing. Then go to mounts and storage, and format system, data, and cache. Choose install zip from sd card and choose cm7-vibrant-initial -20110224.zip. As it is installing, one of the last things you see should be "restoring efs". Hit reboot when finished, and boot into CM7. When it boots, make sure you toggle the lockscreen a couple times so it connects to service. Check baseband and IMEI again. Baseband should have changed to KB1. IMEI still the same right? Awesome! Power down the phone, move to the next step! It's not? You my friend, get to meet all your other friends back at Step 1.
Step 5 - Installing what you really want...
1 - Boot into recovery using the 3 button combo. Do a factory reset, wipe cache partition, go to advanced and wipe Dalvik cache. Choose install zip from sd card, and pick that shiny new version of CM7/MIUI you picked out. You are almost there. Flash it! Reboot, and when it comes back up, take note of what time it is and DO NOT TOUCH THE PHONE FOR 15 MINUTES. You have no idea the amount of bugs this squashes. After that, check the baseband, it will be KB1 unless the rom you just flashed changed it. Check the IMEI, even though you already know it is right anyway. If it is not, do i have to say it again? You know where you are going...
2 - Destroy the paper you wrote your IMEI on, you would not want that info in the wrong hands...
3 - Enjoy your new rom
FAQ:
Q: I did everything you said, and it did not work!
A: You either skipped a step, or did not stop at the point I told you you were screwed.
Q: No, seriously, I did everything you said!
A: Seriously, I have done this 5 times in the past 3 days, and it worked every time.
Q: I installed CM7 nightly #9,10,or 11 with this method, and I have no sound on calls. What gives?
A: These builds have known issues with in call audio. Flash CM7.1
Q: Once I am on CM7/MIUI, do I have to do this every time or can I update normally?
A: Once you are on CM7 or MIUI with the proper IMEI and a good baseband, you should be able to update via the rom posting instructions. If you decided to switch from CM7 to MIUI or vice versa, I would go back to this process to get your initial installation.
Q: I installed CM7.1 and then tried to go to MIUI, and lost everything again, what happened?
A: There are changes betweeen CM7 to 7.1 that have made this difficult due to compatability issues, which is why I recommend doing this process again if you want to switch between the two.
Q: I thought there was an easier way to do this, why so many steps?
Read the first paragraph of the post, but I guess that is also asking too much...

Great post. Thanks for the info...

Pretty sure you can install the latest CM7 just via clockwork2.

i thought the baseband loss was due to kernel compatibility with the newer versions of CM7/Miui? Good post nonetheless hope it helps people out.

That is the first paragraph of my post. And it has already been stated that people are losing IMEI/Baseband anyway. This always works, period. Thanks for the input.

I did the steps properly and now my phone only boots to recovery...

yup i do this every time - the last few attempts with the quick two file flash method is causing all sorts of crap to go wrong on my phone even from a fresh odin - i am pdy05 and i approve this message
-screen tearing
-wifi drop
-incorrect model
-no cell connection etc....

I've done this twice now, and yet again I end up in a situation where my phone will only boot to Clockwork Recovery.
If it helps, Clockword always says E:no misc partition at the bottom. Never seen that before with all of my flashing endeavors.

Nope, I was previously running CM7.1. I said **** it and installed 7.1 from CWM2 and it worked perfectly. IMEI is correct and everything.
It seemed to **** up when ODINing the initial kernel.

Glad it worked out for you anyway, may have been a bad download. Those are the exact files I use to do it... and I am on CM7.1 using this method after losing my IMEI trying to go from clockwork 2...
Was it when you tried to boot into clockwork 3 for the first time, or after you wiped and flashed the initial rom?

Completely clueless, but that is why I put this up, so after I had a definite way to fix mine, others could fix theirs. The problem itself seems to be more with MIUI than CM7, but it is happening with both. I would not be surprised if it happened to more people who have simply not checked their IMEI, and are working off a generic one because they have service.

Curious what happens if the imei is in the wrong hands and stolen
- excuse my grammar im using swype-

My external sd card is not recognized after successfully booting MIUI. This has been bother me for days now... I see sd card icon in the status bar and it says "sd card safe to remove" I tried mounting/unmounting/formating - I only see the main partition when i plug usb cable to windows. EMMC folder is empty as well.
Does anyone else experience this?!

what i dont understand is Rom manager premium made it so easy a baby could install it! download rom off rom manager premium CM7 nightlies make sure u flash clockwork recovery vibrant mtd and 3x and not 2x! install download and wait......way too easy!!!!!!!!!!!!!!!!!
Make sure u wipe data, wipe dalvik and backup rom when it asks its pretty simple.

I've got a better way, install Rom manager, select rom, click flash. TADA!!!!

LG Marquee has CWM.

Okay guys, I thought what the hell, I'll try the LGE Black option in ROM manager and see what happens.
IT WORKS!!!!!!!!!!!!!!!!!!
Use the volume keys to move and the search button to select.
The first boot into it, you will get all kinds of errors saying it can't mount certain files.
Go to "Mounts and Storage" and select "mount /cache". The errors will go away.
Everything seems to work as it should.
A quirk that I found was that until you "Wipe cache partition" you will be stuck in recovery and you cannot get out. Once done, "Reboot System Now" and everything works great.
One last thing, I cannot figure out how to key combo into recovery. I have to use ROM manager to access it.
NOTE:CWM messes up turning off the phone. Pressing the power button and selecting OK to turn off will now reset the phone and then boot it back up. Now only way to power off phone (besides pulling battery) is to use ROM Manager to boot into recovery, wipe the cache, then select power off.

good news dude

no key combo on Black, I think it's the same on Marquee

This seems weird; does CWM allow you to make a backup?

I have tried and you do not get a complete backup. You do get the boot and recovery img files but not much else.
I have tried (without luck) via twitter to contact Koushik Dutta, the man responsible for CWM. We really need his assistance for this to move forward.

well, I know its possible to use the Android Terminal Emulator to flash a custom recovery image from your sd card;
thedroiddemos.com/2010/07/23/how-to-flash-a-custom-recovery-on-android-tutorial
I wonder if it can be used to generate an image of your phones current state to create your own back up and file it on your sd card.

Haven't tried to do any type of restore yet. I have managed to get the boot and recovery IMG files and used adb to get a copy of the system files.
(The LG-Black Dev's are using these files to develop their Gingerbread version.)
I might try to figure out how to do this from the link you gave. If I do, I will post what I find out.
Honestly though, after guinea pigging the root and CWM without total bricking the phone, I'm afraid of pushing my luck too far.
It would be nice if some more people would jump in and help with some of this but I guess the phone is to new to have very many users. Seems like I see the same few names on the three Marquee forums I know of.

I know what you mean. I'm starting to think you are the only one out there with a rooted Marquee.
Hang in there... I think once all the chaos from the iphone settles down, more people will have the Marquee. Most stores in my area are saying they don't even have it. They don't even have them on display.

any response from koush?
Also, I was wondering...
I often download files from peers in forums instead of going strait to the source. I saw that you got CWM from the android marketplace via Rom Manager...
Do you have the premium version?

also, I was reading at the link above and noticed you can email koush directly for help with CWM via [email protected]

Also, according to this;

it mentions the following;
"Did flashing break your recovery? Flash an alternate/experimental one and flash back to fix!"
I'm still looking for a place to download alternate/experimental ones but I think the latest is here;

hey guys, I have done a backup of my stock rom from cwm, I think it worked, but I have no reason to flash it back yet, I'm as geeked as everyone else for roms on this thing, but I still miss my captivate, firefly was awesome

But I honestly haven't had enough time to delve into this much. I had the Marquee for about 2 weeks or so, but had to temporarily switch for work-related reasons. Will probably switch back to it as my personal phone, so I would love to see / hear some progress on this.

Didn't work quit as well for me... When I tried to mount the cache I got an error. The only way I could get out of the recovery screen was to 'Wipe Cache Partition'
By the way THANK YOU for posting that. I could not figure out how to get out of that screen. My phone is rooted and I have been waiting for people to develop... but it looks like there are not many people developing on the Marquee

BTW I posted a request for the Marquee on Cyanogenmod facebook page... if we all do the same we may be able to get some love.

[Q] Unable to boot tablet.. please help

Hi I hope someone can help me as i'm a little stuck how to proceed....
Basically I purchased a new P7310 tablet 2 days ago with the idea of installing lovely JellyBean.
I firstly 'Rooted' the following the instructions on http://forum.xda-developers.com/showthread.php?t=1406137 and then installed and run 'Superuser' without problems.
Next I installed 'Titanium Backup Root' and 'RomManager from ClockWorkMod', I run Titanium Backup Root and carried out a full system and apps backup successfully.
Next I connected my tablet to my Windows PC and downloaded the latest two ROM zip files from http://forum.xda-developers.com/showthread.php?t=1777398 and copied them to the Root of my SDcard.
I then disconnected my tablet and clicked the 'RomManager' app, once opened I clicked on the 'Boot in Recovery' button and a message appeared saying it needs to install the Recovery Manager, so I clicked OK. Next a success message appear saying it installed OK. So I decided to click the 'Backup ROM' button before I started just to be safe but the tablet switched off... black screen, it then loaded up but the Samsung logo flash up then disappeared.
Now If I try to power on the tablet I just get to the logo then powers off, if I try to boot into recovery mode it displays the two icons on the screen ok but selecting the left icon (with mini android character) it powers off. If I select the other green icon it shows me a message about installing custom roms and asks me to connect the tablet to a USB... followed by asking about 'odin3'?
I'm totally confused what I can do now, as I say I haven't actually got to the point of installing the JelyBean Rom, I just wanted to make a few backups first.
Any help much appreciated..thanks.

From further investigation I think I have soft bricked my tab :crying:
Now trying to find out how I might be able to fix it, found this post which I really hope will help me - http://forum.xda-developers.com/showthread.php?t=1133590
Any help with trying to fix my tab would be great.. thanks.

Fixed it thanks to this forum :victory:
Encase anyone else has the same issue I just downloaded the original ROM file for my UK P7310 (P7310XEUKJ4_P7310XXKJ4_HOME.tar.md5) which was approx 600MB (once extracted to desktop) from http://forum.xda-developers.com/showthread.php?t=1582943
And followed the screen shot instructions further down the thread from user 'suwandiapr' which informed me which options to have selected when runing the 'Odind3 v1.85' application.
The whole process took around 10 minutes to complete.

Sounds like ROM Manager screwed you. This is why I'm not a big fan of these Play Store release ROM/recovery installers. You can't test on every device, therefore there are going to be issues and some people are going to end up with bricks. Sure, they're convenient, and they work most of the time, but when they don't work, it has the potential to be catastrophic.
IMO, stick with flashing things through working recovery (or Odin the first time).
EDIT: Also, glad you're back up and running.

had same problem with p7300 after Rom Manager.
now using cwm for total backups and 'my backup' for applications when moving between different roms.

I'll second everything said. Always use a recovery to flash a rom. Never rom manager or other such things i hard bricked my i727 using goo manager. Don't trust the rom either rom manager or goo manager say are compatible with you device. Pretty sure my hard brick was from a gapps goo manager said was compatible with the rom. Check xda and what others have said works
Sent from my SAMSUNG-SGH-I957 using xda app-developers app

The best option to flash any rom is from the cwm recovery, unless its a stock rom and u want to use Odin from dl mode. Also, some versions of cwm recovery are deemed dangerous for ics. Pls visit tracids thread in development for details.

Cannot get into recovery

I have a LG Thrill that is stock ICS. If I boot the phone and check all the buttons the buttons work, however when I try to boot into recovery the phone just boots or turns off. I hold the 3d and volume down button then push the power button until a vibration and lg logo then release the power button. I've tried to go thru adb to reboot into recovery but I cannot see the device in adb.

Have you actually installed cwm recovery?
Sent from my LG-P920 using xda app-developers app

No, I'd love to be able to install CMW or TWRP but the guides I have found all say that I need to be able to boot into recovery.

You can install CWM (or TWRP) by flashing it with Fastboot, but you will need to place a recovery image file named "cwm.img" in the CWM folder in the Fastboot pack. Some available packs (check the Optimus 3D dev section, same device, Euro flavor) have the image files already included, I think.
The method I have mostly used is to flash xbsall's rooted ICS with recovery.
http://forum.xda-developers.com/showthread.php?t=2195753
His rooted ICS uses a type of recovery that is in system partition (not recovery partition). So if you want that, or you do not want to flash your device, use Fastboot (or one of the customized variants)

First, thanks for the help. I now have superuser available and couldn't be happier. The reason I decided to do this was that I couldn't get the wifi to switch on and even with the super user access it won't. Should I assume that this is a problem with the phone or is this something that would work if I were to roll back to gingerbread?

It's most likely a problem with the ROM/kernel you're using. I'd switch to another.
Sent from my LG-P920 using xda app-developers app

I can't say thanks enough for holding my hand so far. Is there a good guide that you would recommend for me to look at. Some of the ones I've viewed here have different information for each of them. Is the reason that thus phone is so different from what I'm used to due to the omap processor?
Sent from my SGH-I727 using Tapatalk

I had the wifi problem a while back; it was due to me installing a custom ROM without doing required wipes in recovery before installing it. Not sure how you got to ICS, but if you follow the guide I linked above it should solve your problem. You don't have to install the custom ROM if you don't want. Just stop after installing rooted ICS. Be advised that driver install for pc is fiddly, hence the detailed install instructions.

Can anyonne throw me a line here. When I install the omap drivers for the phone (step f4.1-4.5) the phone still keeps disappearing from the device drivers. Even disconnecting and reconnecting with the volume up button pressed isn't helping. Any ideas? I've tried uninstalling all of the drivers, using system restore to roll back, different cables. It used to work, now it doesn't any ideas?

If you mean the way it keeps blinking on and off, be ready with the mouse. Watch for when it appears and quickly right click on it, you kind of have to catch it. Then point it to the driver in the Fastboot folder (not the one in the omap4flash installer folder) as described. Once that is done you unplug phone, then replug, volume up, and let the two LG drivers install. All LG stuff on pc should be uninstalled and pc rebooted before beginning with all this. Also, some antivirus software can mistake the driver as being malicious and delete it when unraring the Fastboot folder, without it notifying you. And if you have a custom bootloader on your phone you may need to skip running omap4flash installer; they seem to not agree somehow.

[Q] LG D415 L90 - Stuck On "udc_start()"

This is the first issue with an android phone I've had in a while where I have absolutely no idea what I should do next.
The music player was beginning to stutter a LOT on my install of CM11, and I was having issues where if I selected a song to play on my music player, the volume would suddenly spike to THE HIGHEST LEVEL, and I had to adjust the volume down to get it to reset back to normal. So I figured I'd wipe everything clean and re-install CM11. I didn't just wipe /data and /cache, but I also wiped /system because I believe the issues mentioned above came from a Sony Walkman Mod ZIP I flashed. So after formatting all of the partitions, I went to the "Install" button of TWRP (by the way, I am using TWRP 2.8.1.0) to re-install the CM11 ROM. When I tried to open the CM11 ZIP, TWRP gave me an error saying it couldn't open the file to flash it. I tried using adb sideload as well but adb sideload gave me a similar error.
So I figured it was just an issue with TWRP and that I'd have to boot into fastboot and flash a different recovery image that I know works, like shinobisoft's CWM. I power off the phone, hold the volume up button while plugging the phone back in to the USB port and I am greeted with the Download Mode screen as usual. Here's where things start to get unusual: instead of the phone taking about 1-2 seconds and presenting me with a "Fastboot Ready" line of text or something similar to that, the Download Mode screen hangs on [270] udc_start().
What should I do from here? I tried flashing back to the stock KDZ, but Download Mode needs to be working to do that. Also, I can still get into TWRP recovery just fine, and TWRP can still see all of my partitions.

This is the first issue with an android phone I've had in a while where I have absolutely no idea what I should do next.
The music player was beginning to stutter a LOT on my install of CM11, and I was having issues where if I selected a song to play on my music player, the volume would suddenly spike to THE HIGHEST LEVEL, and I had to adjust the volume down to get it to reset back to normal. So I figured I'd wipe everything clean and re-install CM11. I didn't just wipe /data and /cache, but I also wiped /system because I believe the issues mentioned above came from a Sony Walkman Mod ZIP I flashed.

I tried your suggestion of holding the power button but that didn't work. And this is the ONE TIME where I did not make any backups. I couldn't because TWRP couldn't read my /data partition since my phone was encrypted, but before this whole thing happened I formatted /data as EXT4 (which I did before without issue), so I don't think it should be encrypted anymore.

What I said about the power button was only to help you get out of fastboot mode so you could try to get to fastboot mode again. LOL.
BTW, I always have a least 2 backups on my sdcard.
You're in a bit of a pickle... I need to think about this for a few...

**BUMP***
I went back to TWRP and tried flashing a PurePerformances .zip and it was able to flash just fine. But even with a fresh download of the CM11 ZIP It still doesn't work. Maybe I'll try flashing a different ROM.

That's really strange. As I stated in my ROM thread, I haven't changed anything with the last build...

Whoa, just noticed the 12/2 build! I was trying to flash the 10/22 this whole time. I'll try flashing 12/2.

I tried the new build with ADB Side load. It was able to load the zip!
But the device could not be found...

So ADB debugging isn't enabled in TWRP 2.8.1.0? Have you tried another recovery? And why sideload? Why not straight flash?

I can't load another recovery on here without going into fastboot. And I am currently in the process of attempting a straight flash. I am going to save the rom on an SD card on another phone then inset it in the L90.

I've never had this happen to me before. What's weird is the cable was able to transmit power to the device, but not data.

Ya got me. I use the same cable for PC communication. My main charger is a hardwire charger so I basically just leave my data cable attached to my PC. In fact, it's the same cable I started modding my P506 with about 2 years ago .

Speaking of feeling stupid, is that the fastboot screen? Like, if I have that screen and it says "hold up till download mode" does that mean I can do fastboot commands like that????? Maybe I DID enable fastboot mode????

Yes, that is the fastboot screen in the picture and it passed the UDC START. What you have to do is power off the phone, hold volume up while inserting USB cable to phone, and KEEP HOLDING VOLUME UP until you see something like "fastboot: processing commands". Then you will be in fastboot.

I don't think I got it. It goes into the screen but if I hold down the button it stays the same. I unplugged the coed and plugged it back in (saw something about that here but I can't find it again) fastball devices comes back with nothing. Fastboot OEM unlock gets "waiting for device" as does fastboot reboot and fastboot flash recovery recovery.IMG (I have twrp in my fastboot folder called recovery.IMG) does download mode look like all the rest of the LG phones I have seen with the S/W UPGRADE IN PROGRESS DO NOT TURN OFF TARGET. Just asking because these things are subject to change!

Download mode and fastboot mode are the same. S/W Upgrade mode is totally different. S/W Upgrade mode is what you should have if you DIDN'T zero out your laf partition. If you did zero out your laf partition, then you should have access to fastboot/download mode.
If the fastboot executable isn't recognizing your device, then you must be in S/W Upgrade mode, or fastboot mode on the device had become corrupted somehow.
I remember reading in the Android Original Development section that you used the script to increase your internal data storage. Does that script mess with the laf partition? If so, there's your issue.
