I just want to verify a few things I've been reading about
My phone is rooted.
1. The current releases of Froyo are off the pre-release that was leaked, correct?
2.Hence it wont have all the features?
3. To upgrade to a froyo release i would have to wipe, update radio and then flash the update?
4. If i want to go back to say cyanogen 5.0.7, do i have to wipe, revert back to previous version of radio, and flash cyanogen?
---or is flashing back to previous radio not necessary?
5. If i made a nandroid backup of my current cyanogen installation, and I try out froyo, but then decide to restore the backup, do i need to flash cyanogen first before i do so?
Thanks in advance!
1. Correct.
2. I don't know. It appears to have all the features that were promised on the I/O.
3. No need to wipe, but it's somewhat recommended. Radio is included within the update.zip if you download the correct zip of course.
4. Don't know about the specifics, but you don't need to reverse the radio. If you don't, then video recording won't work, and SD mounting might get buggy. You could always switch to CM 5.0.8 test3. It requires the new radio.
5. Nandroid does a backup of everything, except the radio.

So in order for video and mounting to not be buggy to work with 5.0.7 i would need to flash back the radio, correct?
And for the nandroid, i just restore and no need for wiping or flashing?
You would need to flash the previous radio back, yes.
If you do a nandroid backup, then flash the froyo with the new radio, you will have to flash the old radio before you do a backup restore, if you want everything back the way it was. If you just want to test Froyo, do a nandroid backup and then flash the version without the new radio. Everything, except video recording (and buggy SD unmounting), works.
And yes, no need to wipe nor flash on a nandroid restore.

Rather have everything working to get the full experience, i dont mind doing an extra re-flashing step
Thanks for all the help!
P.S. Any recommended froyo builds?
There's only really one right now: the stock one. All others are just apps added to the stock one. Real builds will follow after Google releases the source of the Froyo.

I did a couple searches but could not find a guide to updating my CyanogenMod version. I followed an old ninja tutorial on rooting which linked to v3.4.6. But I don't think I have to do a wipe and all that stuff do I? Do I just have to copy the ROM to SD, rename as update.zip and do the reboot thing? Will I lose my data? Settings? (I know it's a good idea to backup anyway)
Do I have to upgrade incrementally from 3.5-->3.6-->3.7-->etc.. or can I jump to latest version? Do I need to use an updated recovery image, or is cm-recovery-1.2.img okay?
On a side note, I just noticed that there is an update showing up under System Updates. Is that the official Google update? What would happen if I applied that update?
Thanks
just download cm 4.0.1 and flash it. you do not have to wipe unless things start to terribly mess up. i would recommend get the 1.4 recovery image as you can flash any .zip file with it. also you can restore a nandroid backup from it. if something does mess up try running fix_permissions in the recovery console before wiping.
if you applied an official google update you would lose root access but that wouldn't be terribly hard to get back with the one-click root in the market aka recovery flasher.
Thanks david1171.
Does either flashing the ROM or the Recovery Image wipe my settings, apps? Sorry for the noob q's.
Also, someone in a previous thread said to update radio? Is that a separate procedure? Where do I find the latest radio version?
just flashing the rom or radio or recovery image will not wipe anything. the newest radio is 2.22.19.26I. you can check in setting>about phone> under baseband version the part past the U_ is the radio version. if you do not have the latest radio you can get in cyanogen's thread in the first post. and you just flash the radio like a normal rom. the only thing that will wipe your data when you flash it is haykuro's spl.
what do you mean just flash the radio like any normal rom?
do I rename the radio zip file to update.zip, put in root directory, reboot, hold HOME, then ALT+S? Is that what you mean?
I tried to follow the HTC guide for updating radio, but it sounds like you need a developer machine to run those commands.
Thanks

yeah thats how you do it.
Alright, I'm up and running:
recovery 1.4
newest radio
cyanogenmod 4.0.1
Here's a guide for noobs that I found useful:
http://androidandme.com/2009/05/gui...r-rooting-your-android-g1-to-install-cupcake/
It's going to be outdated but at least it shows how to update radio. I didn't realize that all updates were treated the same. Now with Cyanogen's Recovery 1.4, we don't have to rename the files to update.zip.
I also didn't realize that when you do updates it doesn't delete your data folder which houses all of your custom settings, apps, google account info. It just flashes the system files.
I still don't know a lot and don't completely feel comfortable doing everything. Hopefully soon enough, someone will put together a guide to explain all the particulars that are not obvious to the noob. People have already started.
Thanks so much to everyone who has worked on these projects. It's so awesome!
do you have the Hard SPL. if not go to the guide in my sig and you can install it noob friendly from there
First off, much thanks to everyone involved with CM7. The Nook Color is a fantastic Android tablet thanks to your work, I sincerely appreciate it.
I have successfully installed a CM7 nightly build, but I am interested in trying out the recent one which fixes video playback issues. Can I just download the updated ZIP file and install it using Clockwork Recovery on my recovery SD card? Is there another, perhaps better way? Will I lose anything (apps, settings, etc?)
Thanks in advance
Nick
I just did this myself.
What I did:
Open Rom Manager and manually do a backup of your current rom. Its easier to name it something YOU understand that way.
The NC will reboot and do the back then go back to the current rom.
Then download the video test and flash it using Rom Manager- Flash ROM from SD card. I wiped data and cache but did NOT backup current rom, since I had already done so manually. (I am not sure if that is required but I thought it better to test the video clean.)
Once I tested the video (which was perfect) I restored my backup and had my fully configured CM7 with Tablet Tweaks and OC kernel running.

Did you just flash the CM7 tablet tweaks through Rom Manager? You flash the tweaks over an already installed version of Cyan7 correct?
You know, I hadn't been thinking about it until I saw your question but I have been doing extra work- the Tablet Tweaks is the full rom not just an update to a rom....
So the way to get them installed is to find the latest version and flash it through Rom Manager (a "yes" to your question) and then flash the OC kernel through Rom Manager. That one IS an update instead of a full rom so can be flashed over the existing rom.
If I screwed up this post its because I just woke up from a nap.

Let me try to make this stuff clear for any who follow:
*Best to get the regular CM7 nightly installed and working correctly first, I think- less chance of bugs.
*video test and Tablet Tweaks versions are both FULL ROMS and will replace the current rom you are running. Data wipe should not be required for either, but if you have problems try wiping data and do it again.
*the Overclock kernel can be flashed OVER the current rom and will not replace it, just add to it.
If I screwed up this post its because I just woke up from a nap.
So im wondering, what is the standard practise, or based on your own experiences. What is the best way to flash over an existing rom using CWM? What do you do to prepare the fone for new rom, wipe user data, dalvik cache, before or after flashing. Just trying to get a good idea of how to do it.
Sent from my SAMSUNG-SGH-I897 using XDA App
going from rom to rom:
put rom.zip on /sdcard/
reboot to recovery
install zip from sdcard
point to rom.zip
flash
reboot
any rom that has been properly done will wipe user data and dalvik cache for you. no need to do it manually
i always flash back to eclair and master clear with odin one click to make sure all files from previous roms are gone then CWM flash new ROM

Except I do clear the caches manually, but that's just because I have OCD.

lets look at the master clear function shall we?
when you flash to stock...your entire / is stock (RFS, eclair 2.1, /data /system, etc)
essentially, you have just reformatted your root, think of it like formatting your C drive and your sdcard is like a secondary internal drive that contains storage
master clear at this point will only delete items off your /sdcard
roms dont care about your /sdcard, master clear is worthless when you are stock
there was a time where it was necessary to flash to stock to reset the filesystem and then flash the rom. it has not been needed in months, but it continues to get preached as gospel.
even flashing to stock isnt necessary unless you are trying to come from CM7 or MIUI....or if something goes horribly wrong
Thx for info guys, I have flashed a few times and it seemed like now and then my fone must became bogged down and needed to be fully wiped, sound didnt work or lagfix folders bunch of text docs, just seemed cluttered. So if wanted to really clear out junk what would be a good way without having to flash back to stock?

Just flash. If you have a problem then back to stock Ans a MC. I have flashed hundreds of time back to stock once.

I would definitely agree. I have also seen people say to disable lagfix before flashing. I have not done that either and never had any problem.
Would just like to amend the advice already given with the following:
Pre-flashing:
1. Titanium Backup of apps and data
2. Nandroid backup in case something goes boom.
Post-flashing (assuming success):
TB restore of user apps/data only. NEVER RESTORE SYSTEM FILES.
They may not apply to some people, but I feel those are necessary steps for anyone that actually uses their phone daily.

why not restore system files? Does this apply if coming from flashing back to stock first, or just flashing from one rom to another?
Glad to hear the advice about not flashing back to stock, that's been one of the major reasons I haven't flashed quite as many rom's as I want, too time consuming.........not to say that i'm not flashing a couple rom's a week, but there's just so many options to try

Making "search" a standard practice would be very helpful.
Restoring system is known to mess up ROMs in all cases. Though may not be mandatory, but make it a standard practice to flash stock. Takes hardly 10 mins, and helps save big headaches later.

Incompatibilities across rom versions, mostly. As the guy above me said, restoring system files tends to mess up a rom because you are overwriting part of it with files from a different rom.
There is one caveat, however. If you're flashing back to a rom you originally performed the backup on, you can safely restore system files. For example, if you were running Cog 4.3 and did a full TB backup, then decided to flash Serendipity 6.3, you would want to restore only your user apps and user data. However, if you decided to flash back to Cog 4.3 at some point, you could do a full TB restore without worrying about incompatibilities.
I agree with everyone else. Flashing over another rom seldom causes issues. I make s nandroid backup of my favorite rom with everything setup the way i like it. then flash away trying different roms. When i am done, i just restore my backup and all is good!
I have done a search, couldn't find the specific answer I needed, hence my asking. Could be I wasn't phrasing the search correctly......but here I am.....
To clarify, what do you dpo to get your system settings back after flashing a new rom? I flashed to serendipty 6.4 last night, as per the advice, I didn't restore system files, just apps and data, but that didn't work so well for me. I lost my data connection, could only use my wifi, and had no contacts, or any sms msgs. I don't know what else was missing, but I then went and restored system files, everything came back as needed, and there seems to be no issue......
How do I get my info setting back, or do I just need to manually re-set everything after flashing? Apart from wireless info, msgs and contacts, what else do you lose by not restoring?
Appreciate your help
havent flashed a new rom in a while and forgot if anything extra was needed when flashing a rom over a rom
thx!
Hello,
I am trying to install CM7, the stable (bbq) version, on my gfs n1. I downloaded the zip, did a nandroid backup just in case, applied zip and rebooted. It opened to the CM7 load screen and i thought everything was working. Waited on that blasted screen for 45 mins and nothing happened. Did a battery pull and restored from the backup and everything is working how it used to. I am trying to figure out why the CM7 install didnt work.
I think it is because of the radio. She is coming from 2.1, an old CM rom. I am not sure which one. I didnt update any radio before i flashed the rom. I didnt know which radio to flash. The newest radio is a Korean radio. Should i flash that before i do CM7 flash. Any advice would be great. Thank you.
yes, you should have the newest radio, korean radio is ok for usa use.
alright, ill flash radio, then flash rom, then reboot. Ill let you know if i blow anything up. Thank you =)
Did you wipe everything?
i would do a full wipe ...yes
Did you flash gapps file also?
Full wipe should include system partition also.
FYI radio 5.08 is what come with 2.3.x ota. Radio 5.12 should work no problems.
will i lose all settings, files, apps?
is there a way to keep everything and change rom?
I would say it is good practice to do full wipe when switching to different ROM generation.
Once you are on CM7 upgrading to never version is OK with just caches cleanup.
In your case I would use TitaniumBackup or any similar app to backup all the apps. In theory you could try to restore the app data but may not work properly. Use as much as possible backup/recovery build in the apps.
BTW consider app2ext - I do not known if such a feature is available in FM - search the forum how to create separated partition on your SD card
well i gave it a try.
updated OR, did all 3 wipes, installed the latest CM7 and rebooted.
i just got the M sign no matter what i did.
had to nandroid back to my latest backup.
never had that in any froyo mod.
is it hopeless?
should i try again?
When you wipe, go into the partitions menu and format boot and system too.
Sent from my Droid using XDA App
how exactly?
didn't find it in the OR menus.
Don't do that!
There's no data of /boot in CM7 packages!
Switching from Stock 2.2.1 to CM7 worked flawlessly for me back then.
Try downloading the CM7 .zip again, apply it and do all 3 wipes afterwards.
tried again, like you said.
didnt work. back to froyo.
bummer.
ok, tried the HO NO mod of this rom and its working!
looking great. thanks for your help.
this HO NO is a version of the original CM7. meaning if there are future updates to the original CM7 i will be able to update, correct?
i wont have to necessarily wait for a "HO NO" version?
It's not that easy.
HO!NO! is a CM7 mod - that's right.
But if you mix updates from both HO!NO! and CM7 you will very likely end up with the M-screen or bootloops again.
Usually it's like this:
Update the ROM you're on: flash zip, wipe caches
Change to a different ROM: flash zip, wipe everything
