[Q] Want to go from CM7 to ICS, need some help

The last time I flashed a custom rom to my phone was CyanogenMod-7.1.0-RC1-N1.
I'd really like to get ICS on it, but the process seems just so much more confusing this time around. If anyone give me a breakdown of what I'd need to do, or even if they could just point me in the right direction, I'd be grateful.

i never messed with that as they are always a lil buggy i like sense better ^_^ try asking people in that thread im sure they be happy to help you bro
sorry i couldn't help

There are at least 3 ICS ROMs with 2 are in the working progress and the other we don't know what is the status of it. Spend some time to read first to gain some knowledge and procedures. They are in the Development section of Nexus One. And, remember, once you have Ice Cream Sandwich you don't want to have Gingerbread

u can flash this miui ics as like anyother roms before
http://forum.xda-developers.com/showthread.php?t=1479348
but for other ics roms u need to partition /system. for that first u need to know abt blackrose.

The process is actually easier than the process you went through to root your phone and install CM7.
First, download the ICS firmware zip file to your phone's sdcard.
Next, make your backup using TitaniumBackup.
For most ICS firmware, you'll need to repartition your hboot. Google for blackrose-manual_120216.zip, download to your computer, unzip and look for the hboot_brcust-220-10-206.nb0 file. This one is pre-configured with the right partition sizes. Follow the instructions in the README file, which are basically:
Update your recovery firmware, by downloading to your computer and then using fastboot from your computer. I used the Amon-RA recovery for CM and stayed with it for ICS.
On the phone, enable USB Debugging in the CM Developer settings menu.
Boot the phone into the bootloader and go to FastBoot mode. It'll tell you what HBOOT you currently have. Read the instructions in the blackrose README to see which (if any) of the goXX.lol files you need. Then, on the computer:
Code:
fastboot flash recovery goXX.lol
fastboot flash recovery recovery-RA-passion-v2.2.1.img
Next, flash the new hboot:
Code:
fastboot flash hboot hboot_brcust-220-10-206.nb0
The blackrose-manual zip contains fastboot binaries for Linux, Mac and Windows. If you need a fastboot for FreeBSD, send me a PM.
Then boot into recovery, do a Nandroid backup, then a full wipe, then install the ICS firmware zip you put on the sdcard earlier.
That should be all. Once the new system is booted, you'll use Titanium again to restore your apps.
For what it's worth, the BCM firmware is based on CM with all the CM additions you're used to, so things will be pretty familiar. It's running well for me.

Restore apps from GB backup might bring FC. It is better to download them from the Google Play

While, in theory, you are correct, I restored my GB apps using TB because it is very fast to do so. In practice, they all appear to be working just fine. I believe I have run every one of them to make sure.
But I agree that a better general procedure would be to restore the apps themselves from the Play Store then restore your former app data using TB.

This is great! I found blackrose_manual_120216.zip, but the only .nb0 file in it was hboot_blackrose.nb0. Will this work, or do I need to keep looking?

The instructions are in the Blackrose thread in the Development section, you don't need to use the manual if you're using Windows.

I would read the blackrose thread so you understand what you are doing and why. Easier to get out of trouble and harder to get into it. You probably did same for CM7. The blackrose hboot is not easy to work with without knowing what you are doing. The backrose thread has pre requisites in OP, like install of drivers if you don't have them.
You guys sure the fastboot command for the exploit has the word "recovery" in it or should be:
fastboot boot go.lol
where go.lol is exact name of exploit from the actual blackrose binary folder depending what version of blackrose you are fastbooting. could be "fastboot boot go2.lol" etc
just a suggestion--

So I was able to use blackrose to repartition my system cache, but now I've got a problem. In the bootloader, when I select "Recovery" the phone hangs on the Nexus "X" logo, and I'm unable to get my phone to reboot into anything but the bootloader.

you probably lost recovery and need to re fastboot it
i once had to fastboot erase system before the recovery would flash
all these issues are in the thread

Would this be the correct thing to do? http://forum.xda-developers.com/wiki/HTC_Nexus_One/Recovery_Images

good info but if you have sdk and know fastboot do this
Copy recovery-RA-passion-v2.2.1.img to a location where fastboot can find it. Usually tools folder.
Boot your phone into fastboot mode (power on while holding the trackball)
Connect your phone via usb to your pc
type fastboot devices (to make sure that fastboot "sees" your phone)
type fastboot flash recovery recovery-RA-passion-v2.2.1.img or whatever exact name your recovery is

I was able to get into recovery, but now when I select "Flash zip from sdcard", I get an error saying that there was No Signature and that the Verification Failed.

You need to disable the signature verification in the recovery and then flash the ROM

Thanks so much for everyone's help! I've got ICS up and running now thanks to you.
Since this forum account is too new to post in the BCM thread, I guess I'll try asking a question here instead.
So far there's two problems I've encountered that would be dealbreakers for BCM. I saw on the BCM thread that voice search is currently broken, but it seems like it's kind of unexpected and will likely be fixed. The other issue I have, that I can't find anyone else complaining about, is that I don't seem to have the Car Home app anymore. Has anybody else run into this issue, or know a fix? I use my phone in my car pretty much every day in my car dock, and make extensive use of both the car home app and the voice search feature for getting navigation directions.
If there's a better place to post these questions, feel free to let me know!
Thanks

audio has been ab issue for me and others on ics and sense roms lately, don't know why. i am back on CM7 Kangs atm bc of it. hope it is found and fixed. the current remedies don't work for me
glad you are up and running, all these roms have issues of some type for a few at least. goes with the territory--
someone should be able to get you a car home apk you can install or push thru adb--i always delete mine as i don't use--sorry. might be able to find it thru search/google
posting here is perfectly fine--it a couple general threads for a "meaningful" post and you will be to ten real quick
enjoy rom

Sorry, I wasn't watching this thread over the weekend and I see you have already moved past this. But to answer the question...
I thought the pre-partitioned blackrose-220-10-206 was in that zip, but I see now that I found it on the Evervolv ROM thread in the Nexus One development forum. Sorry for not remembering to mention that.

BCM Version RC3.3Ux has very broken voice input. Many folk (including me) have commented that no VoIP apps work with it. Hopefully this will be fixed soon. BCM3.2U2 works fine, so I have reverted to that version for now.
You can install the CarHome app from the Play Store; it doesn't seem to be included in the BCM zip file.

[Q] Re: Hasoon2000's HTC Vivid All-In-One Kit

Hello,
I cannot make sense of either the written directions or the Youtube video. They assume knowledge that I do not possess. Speaking of which...
In the "flash a recovery" step, is this supposed create a recovery image of some sort, or flash an already existing one onto the phone. If the latter, where does this recovery image come from?
In the kernel step, it says to place your kernel in the /Data/Kernel directory. How am I supposed to obtain the kernel image?
Thank you in advance.

Assuming you are S-on you dont have to flash a kernel if you are just rooting it
Root your phone, S-off it(If you want to... I recommend it), and just flash a rom via recovery
I believe the recovery is in the folders already? Can anyone confirm?

Correct CW or WCX just have to choose which you want

It's pretty straight forward and noob friendly...follow instructions to unlock bootloader, choose cwm or wcx recovery then press button to flash...kernel is optional, if you want one download one from here and put it in the kernels subfolder...
Everything comes from/is located in the data folder and its sub-directories you also extracted

Thank you
Thanks for the replies. I found a simpler to follow method, using fastboot.exe and an included recovery image, and successfully rooted the phone.
Now, I'm going to do some RTFMing, so this won't be an issue again.

One piece of information that might help you is understanding that the term "recovery" can mean two things. In the context of "flashing a recovery" in the process of rooting your phone, what this means is flashing a recovery tool to the recovery partition of your phone. Your phone has a special place set aside for a backup OS (or recovery tool) in case things go south for your actual OS. The recovery you can flash with the all-in-one tool will install CWM (ClockWorkMod), or WCX. Personally, I use CWM. By holding the power key and volume down when you start your phone, you gain access to the boot menu, where you can load the recovery tool. This allows you to do all sorts of powerful things, from flashing kernels and ROMS, to preforming backups and restores, to clearing caches, and all sorts of other power-user type functions.
Hope that helps, and glad you got your phone rooted. These things are a lot of fun once you open them up a little

[tutorial][updating TWRP for 4.4 compatibility]

Ive noticed many people with older TWRP versions having problems with the updater script when installing 4.4 roms you need to be on the latest version of twrp (CWM may also need to be on a recent version). This tutorial will cover TWRP. Goo manager will not work for installing the latest TWRP recovery version on grouper. The following will give you the basics on how to use fastboot to flash a recovery.img (In this case twrp)
Things you will need:
A PC
Android SDK http://developer.android.com/sdk/index.html
TWRP recovery.img for grouper http://techerrata.com/browse/twrp2/grouper
A basic understanding of terminal/command prompt
You will need a PC and the android SDK (SDK http://developer.android.com/sdk/index.html) for fastboot to push the recovery file. TWRP can be found here (http://techerrata.com/browse/twrp2/grouper) you need the 2.6.3.0 version. Extract your android sdk and move your twrp image file (openrecovery-twrp-2.6.3.0-grouper.img) to the platform-tools folder in the sdk (This is where fastboot/adb are). For simplicity's sake rename your twrp file to recovery.img Enter command prompt or terminal depending on what OS you are using (windows/linux) and navigate to to your platform-tools folder in the SDK folder (where you should have moved your recovery.img) using the cd command. (plug device in) Once there check to see if you device is connected and seen with the adb devices command hopefully you will see a wonky alpha numeric code with "device" after it. If you dont you need to enter developer setting to enable adb. You do that by going into settings/about tablet and tapping build number 7 times. That should give you a developer options in settings check to make sure USB debugging is enabled. If all is well reboot your device into the boot loader with the adb reboot bootloader command once your device is at the bootloader check fastboot with fastboot devices you should see another wonky output with "fastboot" after it. The final command to push your new twrp image will be fastboot flash recovery recovery.img You should see some output saying how long it took to push the file it should not take that long. That should cover it! Now you should be good to go with the 4.4 rom's floating around.
There are many tutorials online explaining this process I just thought customizing it to the grouper would help those less comfortable with adb/fastboot. It's always a good idea to know how to use these tools you never know when you might need to use them. Anyone with question's feel free to ask.

Or just install flashify and it basically does all of this for you. I did it and it worked.

That will work. But knowing your way around adb/fastboot can't hurt. There won't always be a GUI to do everything for you.

Actually it's suited to the General section (guides and all). I appreciate you advising the fastboot method (I use it too), but it can b a pain for people who don't have their devices configured (configuring it can be a pain sometimes too). Flashify, as one member said, is a great alternative. BUT you *may* brick your device if you flash something to the wrong block device (possibility of that happening to an expert user: 0.0001%; possibility of that happening to a new user: 1%). Just my two cents.

I agree guys this should be in general. I've never posted anything but a build and didn't even think about it. Do I need to get a mod to move it? As for flashify sounds like a great tool. I've never had the pleasure of using it but if it works and people are comfortable with it more power to it. Personally fastboot is what I'm comfortable with it might seem a little in depth but really its quite simple especially if you use adb for logcats and are setup.

OP No worries, moved and thank you.

To flash 4.4 ROMs one could follow this tutorial, or one could simply flash this .zip of the latest version of CWM:

So, i've bricked it already.
Hello experts and knowledgeable persons!
First, i'm a noob.
I decided to flash KitKat as I play a WebView based game and thought the WebView Chromium of KitKat might make it run faster as it ran pretty slow. On the Paranoid Google+ page it says you need TWP 2.6 later and other sites say 2.6.x. I had 2.6.0.0, so did a backup of boot, data, system and recovery, copied to PC and then tried installing KitKat, it failed. So I updated to TWRP 2.6.3.0 and it failed again, tried a second time and it updated.
The game didn't work well on KitKat, so I restored my original version. I then decided to take screenshot of game not working on KitKat to complain, so tried installing KitKat again forgetting to update to 2.6.3.0 as the restoration of the backup restored the prevous 2.6.0.0 recovery, was a noob and tried again and i'm now left with a Nexus 7 in a boot logo loop.
Restoring the backup fails, as does installing the KitKat Zip or Opensensation . If I try flashing TWRP 2.6.3.0 via fastboot, it says success, but when I reboot the recovery i'm still in 2.6.0.0. I can boot into 2.6.3.0 using "fastboot boot", but it still won't restore the backup or flash. I also have a backup of the OpenSensation rom (wanted to try PDroid and it was the only rom I could find prepatched) which I made on 2.6.3.0, that won't restore either.
So now what do I do, as I don't want to make things worse. I am doing a factory reset before installing. The error i'm getting is "symlink: some failed"", "can't open destination log file: '/cache/recovery/log'" and "E:Unable to open '/cache/recovery/log'"

I'm sure this is not what you want to hear but if all else fails push the factory.IMG you will be starting from square one. You can try pulling your backups off but might as well start over for 4.4

Thank you very much for this recommendation. Really nice. Simple and took out all the nervousness of using the computer to push these files etc.

Won't it work too if you just flash the zip from twrp itself? I'm running 2.6.3.2 and I read somewhere that i can simply install the new version (2.7.0.0.) zip from the recovery itself..Is it right??

Problem installing Clockworkmod

hi guys! I'm new at this forum, so if i'm doing something wrong about rules and regulation, even if i've read them, correct me please! However, i just bough an At&T Atrix HD with stock 4.1.1 and i wanted to install a CM11; i obtained root privileges and unlocked the bootloader, and when i try to flash the clockwork recovery, apparently everything goes fine in fact i get no errors, but when i turn off the device and try to reboot in recovery it displays the "dead" droid with a red explanation mark. I've read in the cyanogen wiki that some firmwares during the reboot overwrite the custom recovery, is this the case? Which is the command or the procedure to reboot the cell in recovery then?
PS: I flash it through the command line by the PC, i got OSx and i tried with the clockwork posted in cyanogen wiki and the one posted here http://forum.xda-developers.com/showthread.php?t=2421418

Hi, first of all, did you installed the recovery with: fastboot flash recovery recovery.img right??
If you did so, you just need to turn off your phone, hold volume up button and power button and wait until it enters to recovery mode. From there you can flash a new ROM if you have it on your SD card or internal storage.

1. You're rooted so go to /system/etc and rename "install-recovery.sh" to "install-recovery.sh.bak"
2. Use Myth Tools to flash recovery (CWM or PhizTouch is included in the tool)
3. Check and Test

thanks to both of you guys!! i've solved with the solution in the second post, just deleting the "install-recovery.sh" script, i was going crazy!! i hope this post will help someone else!
PS: i don't understand why they do not put these solutions in the first posts in important threads like that one i've linked....

Nope. You need to do it manually.
I tried to put that function into Myth Tools but it's impossible to do it via adb commands if the kernel is not enabled "insecure".
That's why I put a guide line in Myth Tools to remind user rename that file manually before flashing recovery.

Not necessarily. You don't HAVE to rename that file before flashing. The newer CWM's detect that file and will fix it for you. All you gotta do is enter recovery and exit it through the menu, it'll prompt about the file, and say yes to it. Problem solved. It's what I do along with flashing a root zip with every stock flash I do; haven't had a problem yet.
"Enter and exit CWM" is a lot easier to describe than renaming or deleting a file on the /system partition...less error prone too.

It's what I do along with flashing a root zip with every stock flash I do; haven't had a problem yet.
"Enter and exit CWM" is a lot easier to describe than renaming or deleting a file on the /system partition...less error prone too.

We are 2, never had problems

Deleted OS

Hey guys,
I was trying to unlock my phone and install a custom ROM so I installed TWRP and everything was going smooth until I tried installing a custom ROM. In TWRP I hit "Install" and click the zip file for the ROM I want (PureNexus) and it says "Invalid zip file format! Error installing zip file '/sdcard/PureNexus.zip"
Does anyone know what the problem is? I can't figure this out. This is the first time I'm doing anything from the bootloader so I'm a bit of a newb. I would be fine going back to stock everything if it means my phone will turn on. I tried installing the official image from google (7.1.1) and I get the same zip error.
So where I'm at is I do not have an OS installed on but I do have access to TWRP. In the command prompt on my desktop it recognizes my phone when I type 'adb devices' but it doesn't do anything when I type 'fastboot devices'.
Any help is greatly appreciated. I'm scared.

Okay, so I figured out what fastboot was and I was able to install Google's 7.1.1 stock image using the command prompt. I was freaking out for a few hours and even though I didn't get the custom ROM I wanted I'm really happy I didn't brick my phone. I've never done anything like this on my phone so it was a fun learning experience
I'm still curious what I did wrong and why TWRP couldn't unzip any of the zip files (PureNexus, Google Stock, etc). If anyone knows I'm still interested in learning what I did wrong.

TWRP: wrong version or damaged;
ZIP: damaged or incomplete download.
Latest version TWRP is 3.2.1.0.

Yes, and the Google factory image isn't meant to be flashed that way. I guess the Google OTA image might be flashed from TWRP, but I haven't tried it.

TWRP will flash an image (. img) file if you set it to by tapping the img button. If you don't have that set and try to flash an image it will error. If you have it set to img and try to flash a zip it will also error.

1. Unlock the bootloader.
2. Install the latest TWRP recovery.
3. Wipe.
4. Install the required ROM.
To go back to stock firmware, just download the relevant factory firmware zip, extract it and run the script. I think a readme file is provided in the zip explaining how to go about it.
Cheers! Happy New Year!
