how to flash a new room to an already rooted phone?

Hi
I have flashed my G1 T-mobile following the the one-click process in here! i have now root access. The ROM is CyanogenMod-3.9.11.2
After all that i bought a trascend SDcard 8GB class 6, formatted about 600MB to EXT4 using gparted on a live cd, winxp and my G1.
The first thing i noticed is that the phone is slower to load up. it stays about 35secs on the G1 logo and then move to android for a total of about 1min to be ready.
Second thing my free space on internal memory went from 38MB to 68MB, i believe somehow the phone moved the cache on the sdcard...if i install new programs they get installed on the phone memory as far as i understand...however i could be wrong on this. i never started the phone without sdcard since, I'm not sure if this could damage the phone in some way.
I would like to have some feedback on this (the slow boot and memory thing) if someone has experienced a similar situation.
I'm thinking to flash my phone again and move to a stable version of Cyanogen so that i can use app2Sd and Cyanogen updater!!
- how can i flash a new room, considering that i have the latest radio but not HARDspl. (as far as i understand the oneclick method doesn't change the SPL)
I was looking at using again the small oneclick software and flash the Cyanogen 4.0 this time, would that make sense since i have already root access on the phone?
thank you for the help

update
After installing and unistalling few softwares i found out that all programs are actually on the SDcard however the Mobile uses still the internal memory for the cache. This doesn't bother me for now since i still have about 68MB free. Basically if you install CyanogenMod and you don't have a partitioned SDcard all software get installed on the internal memory however as soon as you put in an partioned card all programs get transfered automatically after the first boot. At least this is what happen to me. Somehow i got what i wanted and because of this i don't need to flash my phone anymore... maybe I'll flash it again when android 2 is out, if i don't have to change spl, image recovery or anythingelse too risky

I used the 1-click method as well, and I just download the latest cyanogen rom, rename it to update, boot into cm-recovery and apply the update.

One more thing, the latest versions of Cyanogen's rom have auto apps2sd built into the rom. It will automatically move all apps to the sd card as long as you have an ext2/ext3/ext4 partition on your sd card.

Your still going to have the same boot time. It's still going to take awhile to boot, just because you have a custom rom doesn't mean it will boot faster. And to load a new rom either rename to update.zip and update or if you have the newest recovery then you can just flash whatever rom without renaming because you can flash any .zip file.

In reading your post I think you said you wanted to use the small 1 click software to download cm4.0 You are done rooting your phone you no longer need to use the 1 click software.
Just copy new rom (cm4.0.4) to sd card
unplug phone from computer
turn off phone
boot into recovery (home and power at the same time)
flash new rom

when you use one root, it flashes cm-recovery 1.4 so there is no need to rename, just put on the root of your sd and flash from recovery

Are you aware of any reason for the slow boot after partition of the sdcard??

is it the stock 1GB sdcard?

Cause it has to read from the sd during boot up and it has to run the script for the apps2sd

As far as i know i'm not using app2sd yet. I partitioned my SDcard ONLY after i flashed my phone. however like i said i think the phone is somehow using the ext4 partition for something.
You reckon this would be a normal boot time i mean it takes between 50secs and 1.05 min to be ready. Phone is stable as far as i can tell.

I myself am not concerned with the boot time, the ext4 is another filesystem that it has to read and recongize, you basicly have a little mini computer in your hands so how long does your pc take to load up, there are many files and system checks that it has to go through starting up not to mention all the settings and components it has to turn on
Bottom line, if you want something to boot up quickly than get a basic phone because there is a very good way to speed up a mini computer to do the same

Well i'm aware of all this and i'm not concerned too much about the boot time. I'm only trying to gather information and learn a bit more from other ppl experiences. I come from windows mobile and android OS is all new world for me.
have you a similar configuration to my G1? Do you run app2sd? is yor boot time similar to mine??

Just a quick question for future reference...
do i need to put Cyanogen recovery image on the root of the sd card when i boot into recovery mode?
thank you
Kirk

Why did you root your phone? You have no desire to search to even do one of the most well documented things to your phone in these forums. What you need to do is take a DREAIMG.nbh file and put it in the root of your sdcard (or in no folders), then open up terminal emulator and type su then reboot bootloader once that happens wait for it to flash that image. Then you will have the most pimping room on your phone. Also you have amazing boot times. Everything you want.

Hi David
I had specific reason to root 2 different G1 and this is not to play with it or try a new ROM or even experiment new things. I may change my ROM again when a major relase is out (i.e. Android 2 if it has something that i need)
Going back to reflashing the phone.
You now suggest me to use DREAIMG.nbh which is actually mentioned on the guide "hoe to downgrade-root-flash your phone" here
....am I missing something here?? thank you for taking the time to reply anyway.
..I have read quite a bit on this forum and i decided to use the one-click method (because is the quickest and safiest one). I thought reflashing should be as easy. go in safe mode wipe and reflash it. Anyway for my nature i tend to ask/investigate one thing before go and actually do it. My questions are:
- if i press home power right now, considering that i have nothing on my sdcard would it take me to the safemode screen?
- Consequently do i need to have Cyanogen image revovery together with the ROM on my sd card in order to flash a new version of CyanogenMod?
Thank you
Kirk

you can boot into recovery at any time by pressing home and power when the phone is powered down. it will go into recovery no matter what is on the sdcard.
Also the recovery image you have on your phone does not determine what rom you can flash.

wow... i am at a loss for words...... do you even know why you did any of the things you did? did you even read the release notes for cyan's rom's? ALL OF THE ANSWERS TO YOUR QUESTIONS ARE THERE...
if you have an ext partition on your sd card....it WILL AUTOMATICALLY be used for apps2sd with 80%-90% of the ROM's out there today... ITS IN ALL OF THE ROMS' CHANGE LOGS/RELEASE NOTES

if you didnt root to try a new rom or experiment with new things, your better off with the stock firmware...which is why david suggested you flash DREAIMG.nbh

going into safemode wont flash anything.... i suggest you search and find out what exactly safemode is, especially since there was a thread only a few threads below yours detailing it.
All you need to flash a new ROM is the rom on your sd card and a working recovery, as well as anything that the ROM your installing has required which are noted in the changelog/release notes....
nothing else is needed on your SD card, except maybe specific partitioning, which will be noted in the ROM's requirements.
I try to help out here as much as i can when i have time (most of my posts are in Q&A helping out people) but it seems as though no one even bothers to look at the actual forums anymore. They just create an account, create a thread, bug people till a simple question is answered, and disappear forever.....
I came to this site simply to get roms, but i stayed because there was so much to learn and i created an account to help out people as well...i did all of my major modifications without asking any questions....all the questions are already answered somewhere...
i understand its hard to go through all the clutter, but it is starting to look as if no one even cares anymore

@B-man007 i am starting to feel like you do, i had my phone rooted and all that good stuff at least a month before i made an account just to download something uploaded to the forum. I wish i could see how many post i have in a ceratin forum bc i imagine at least 450 or 500 of them would be in this one helping people. Its getting to the point where i no longer care to help people and i thought i had a lot of patience. I porbably do but people are sinking to new lows with the questions they ask...

I think I have maybe 5 posts in dev, most of my posts are q&a and general, but then again half of those posts are from hijacking threads. I just got tired of answering the same questions over and over and over

ROM Manager does not Work

ROM Manager just does not work.
................... So mad anybody buys this program it installs Clockwork Boot Partition but IT DOES NOT ALLOW TO UNINSTALL !!!! This is like a virus.
To make matter worse the program just does not work.
Download any RON from ROM Manager it boots to Clockwork Recovery "the virus" and just sits the with the clockwork Android/exclamation.
Clockwork does not answer emails.
Their Forum is full of people that like me are kind of nobbish and very mad that you can not restore the normal android partition.
Two questions anybody have any clue why the program does not work for me?
Failing that how to uninstall revert back to normal Nexus One configuration?
I seen somewhere where somebody says you download a file.
Run some commands from somewhere??? not sure where. I think if you find the the Android ADK you can connect you Nexus One to a computer, turn on some sort of terminal emulator "how?", type these commands from a promote in this emulator. THEY SAY THIS IS EASY ???
You know I live in Toronto I would pay somebody to revert my N1 to stock and not go through the hassle.
All this rooting stuff maybe nice, Titanium Back up, Shoot me, "Cool ROMs which I can not install with ROM Manager" but the education curve is not worth it in my book.

Did you click "flash clockwork recovery" at the top of the program?

Did you flash anything? Or just root and install Rom Manager?

Here are the steps......
Made sure I was rooted, ran a few apps that require root permissions.
Ran ROM Manager,
Flashed the latest Clockmod Recovery
Select Download ROM
Selected CyanogenMod 6.0.0 "I know it work well at least they say so here"
First time select backup current ROM, I did not go for a wipe, selected Google Apps addon.
Watched and it seemed to back up,
Rebooted but.... everything looked the same.
About phone, looked at Andriod Version 2.2 Baseband , kernal Build FRF91
see CyanogenMod nowhere.
Sucker for punishment opened ROM Manager and it asked me if I wanted to report an error "cancel" tried to install CyanogenMod again, it went staright to Andriod Guy/Exclaimation, hit up volume/power, rebooted.
Now whenever I try again I get Andriod guy/exclamation.
I think if I hit "fix permisions in ROM Manager", Flashed CLockwork recovery again .... I can go back to the first step above.

Have you downloaded a rom off of xda and attempted to flash it through recovery?

You can download ROMs from ROM Manager.
I downloaded them from ROM Manager.

Is Rom manager listed under the allowed list under the superuser apps? And it doesn't seem like clockwork is properly loaded on the system, otherwise you would not see the android/with exclamation mark when you boot into recovery. You would see that the latest clockwork recovery is listed twice on the top of the phone. If you have both lines there, that means you have the latest recovery. If you are still having problems with the latest clockwork recovery to install, have you tried the earlier versions to see if they properly install on the phone?
From my experiences, you need to indeed wipe and install gapps to properly install any rom. Then use titanium backup to restore your apps and settings. Looks like you are already backed up/nandroid before doing so.

Wipe first. My fault I didnt see that you ddint wipe

I know most people say when you download ROMs you need to wipe.
I know with Android this should not be a big deal, enter your Google info, the market downloads everything you paid for and then set up exchange mail again but it does take me a few hours to go through the steps and I been lazy.
Try a wipe......

No one said rooting would be easy lol. Customizing one's possesion, let it be a car to a phone is no real small feat. Like anything, you can go into detail as much as you want or not depending on why type of Rom you choose and like. For CM6, that ROM is excellent for customizing pretty much everything on your phone, but it does take some time to get it to your liking.
If you like a "kitchen sink" ROM, have you looked at eVilD's Sense ROMs? Well thats if you like the Sense UI's really, which I do not mind, but everything is thrown in there lol. BUT CM6 is a great launching pad for a novice, like I still am.

I've had no problems with Rom Manager. which clockwork did you install? the beta or stable one? Cause i know when i was doing mine it asked me.
I did the following steps
1. Root
2. Installed Rom Manager and backed up
3. Downloaded Rom of my choice
4. Full wipe and installed rom (via rom manager)

The OP just didn't root, of course.
If the education curve isn't worth it - just uninstall the application. Because you didn't install anything besides the application - because you have no root privileges - because you didn't root. And since you state that you don't want to learn - then why did you start messing with it in the first place?
The only thing that I don't like about ROM Manager is that it creates a lot of people like the OP - starting to mess with something without any wish for understanding, how it works, screwing things up (or not), and start complaining. You did what you did, you didn't bother learning, so why exactly are you complaining?!

Well I will ignore Jack_r1 who is a troll.
"All boards have them ..... sigh"
For the people that were much more friendly and helpful,
Ok next time I try it I will do a full wipe.

Full wipe won't help you. Installing a root-only program without rooting the phone and expecting it to work wouldn't care if you wipe or not.
Guess you really have no clue...

I didn't bother reading his next post, where he said he had root. My mistake.
I believe he had the recovery installed initially (otherwise he wouldn't see it backing up), but the first reboot to stock ROM removed it. After that, he wasn't able to do anything, being booted to stock Android recovery. And came here to complain. I guess a difference between running a program and rebooting from different partition aren't common sense to understand? Should be a prerequisite list before rooting.
The correct way would be, of course, to reflash the recovery through ROM manager again, but for people who don't understand the concept of dual-booting and think they run an application - that's not obvious (and it's one of the reasons I think ROM Manager is bad, and manual installation is good). And the better way would be to read the guides and flash the recovery manually. And while going any of those ways, whining on internet boards instead of asking questions would be the most unwelcome way.

I use ROM Manager because I'm a lazy bastard and it has worked flawlessly for me. I have literally flashed over 50 ROMs (mostly CM nightlies) and it has yet to fail me.
But people that have no clue what they're doing shouldn't be using a program like this and I'm pretty sure it comes with a disclaimer of sorts? Although I've barely flashed anything manually I did read up on the processes before going the custom ROMs route, it just seemed obvious.

Me too - lazy bastard, that is...
However, there was an issue with one of the ROM Manager updates a while back, where backups wouldn't restore. That's when a bit of manual knowledge came in handy...
Sent from my Nexus One using XDA App

[Q] Installing new apps or even restoring has become impossible.

I am fairly new to all of this but feel I have a firm grasp of things. Having said that, I have lost the ability go install apps from any source. My backups are just files and the market is juat for window shopping. Please help me... Oh yeah, already flashed 2 different ROMs to try to start fresh with no luck.

Could you be more specific what isn't working now that was working before? How are you trying to install apps? from .apks on the phone or by sideloading? Can you load apps from the market? What did you use to create backups?
Best way to start fresh is to flash to stock, and start over. Whats ROMs have you been running?

what isn't working
First off I'm on ROM 3 and I flashed to stock first. Anyways it asks if I want to install an app I click ok and get the action bar bug it never finishes. I've tried from the market and from my SD card. My backups were made with Titanium Backup.
Thank you for your time.

You didn't explain which way you are trying to install an app before the bug happens. All ways?
To be 1000% honest, you're starting to sound like a customer... I'm phone support for a major cable/internet company, and when I ask what's wrong, and it can't be articulated, I DON'T KNOW WHAT'S WRONG.
Feel free to PM me for help or ask in this thread.
If your phone is not right, then flash to stock and start over. What is ROM 3?

lol I accept your point. I will try doing by my own.
My reqirement for the ROM is very simple, to increase my internal memory for atleast 300mb and smooth running OS.. Any suggestion for me.?

are you a heavy app user? i stress this as there's stable roms and some unstable but nice roms...
example..
using my own Holo 2 Based rom...
1.03gb internal memory 23% free at the minute (244mb)
280 applications 129 System/151 User
No errors what so ever.
On App2sd roms ie m1ndh8x4r/Einstein frat/razor (im not dissing or flaming any users roms, just stating facts using app2sd)
using same internal memory as mine and the data2sd script available for those app2sd roms, you won't get passed 225 apps total inc system, as there's something in the script creating and error in the dalvik storage, this is an ongoing problem and has yet to be fixed lol.
if your a light weight user then any rom can be used, if your a heavy user like me...then you have my rom only at the minute.
based on your 300mb idea..id would suggest a nicely themed one....check my website for rom details available on older roms.
roms at the moment consist of 2.3.3 (Mine), 2.3.5 )Wildfire S Port), 2.3.5 (Pico Sense 3.5 port)
All roms 2.3.5 and above are non Salsa based, there all ports.
so there's advantages and disadvantages...you make the choice based on your needs.

You could try reverting back to 4.3 then update to 4.4.2 by installing a custom rom.

By any chance your extreme lag also affects the audio performances? I and a friend of mine had in the same period (for 2 weeks) EXTREME lag, signal lost on mobile network. The lag was so powerful that even music was interrupted. The only way to get rid of this was rebooting the tablet.
The most awkward part is that the bug persisted over ANY KIND OF ROM/KERNEL. Even the official one from Google Developers (any android version).
Best part: It was fixed by itself. Lags started to be increasingly rare and at some point they stopped.
I tried to catch some logs...at the moment of failure, just once they pointed me to some lines in the source code...so I quit trying to figure it out what happens..

I had the same problem, I solved it installing SlimKat, but probably you can solve it with any custom rom, I tried many times to restore 4.4.2 but always the same, only installing custom roms seem to solve it...
I remember it, is like a nightmare to me, turn the tablet On and let it 5 minutes before open any app, open Google Play and see how it lags, installing apps always causing freezing... It remembers me my Windows XP years...
At the beginning i let it thinking it will solve itself, haha, after months I was about to broke it with a stone

By any chance your extreme lag also affects the audio performances? I and a friend of mine had in the same period (for 2 weeks) EXTREME lag, signal lost on mobile network. The lag was so powerful that even music was interrupted. The only way to get rid of this was rebooting the tablet.
The most awkward part is that the bug persisted over ANY KIND OF ROM/KERNEL. Even the official one from Google Developers (any android version).
Best part: It was fixed by itself. Lags started to be increasingly rare and at some point they stopped.
I tried to catch some logs...at the moment of failure, just once they pointed me to some lines in the source code...so I quit trying to figure it out what happens..

Ya the tablet is extremely slow, and freezes sometimes for some seconds!
What do you mean with "rebooting the tablet"? Factory Reset on the original recovery menu?
Thanks.

If you want to keep the official rom you can just try to reflash 4.4.2 wiping everything, just copy to PC the files you want to keep and after flashing copy again to tablet, i would recommend you to copy only important data, not everything, and specially not copy the folders with strange names that you dont know what they are

It's necessary root?

Before flashing anything try to restore the tablet, copy all your stuff to PC and format it by going to settings / backup and reset / factory data reset and checking to wipe all on internal memory/sdcard
It will wipe all your data, apps and everything, so be sure that you dont forget anything to be copied to pc.
Maybe it solve the problem without flashing
About root and flashing:
You dont need it, but you can root it if you want after flashing,
I dont know how much you know about flashing and all that, so Im gonna make you an quickly tutorial
Basically all you need is:
Nexus root toolkit from here: www.wugfresh.com/nrt/
4.4.2 firmware (can be downloaded directly from the Nexus Root Toolkit)
And be sure that you have copied to PC everything you dont want to be deleted, you can just copy all to PC and after flashing copy to tablet only what you want...
On tablet turn on USB debugging, on developer options (To unlock it go to settings /about tablet /build number and click it many times until it says "you are now a developer", then go back and you will see it)
When its done follow the Nexus Root Toolkit instructions to "flash stock + unroot" (by clicking a button with that text) you should select Android 4.4.2 (KOT49H) and check the option "automatically download"(dont remember what the option says exactly)
And the tool will download it and tell you when you have to do something. Just dont disconnect the tablet until the tool ends its job
Maybe you should install some drivers if you get an error message like "device not found"
If you want to know more about insalling drivers, you get any problem or something else just tell me, but maybe im gonna make you wait because tomorrow is my birthday and I wont be checking it for few hours.

No...just a simple restart. As I stated, I tried different resets and flashes and everything and nothing worked...

Be careful about "Returning to stock" method as I think Google broke their "flash-all.bat" from the arcvive of Android 4.4. Flash every file by your hand. I used that idiotic flash-all on any android version, but on 4.4 it completely broke my motherboard by flashing wrong boot.img.

Okay, I was no sure that you also format "SD card" factory reset do not delete user data/sd card on some devices and Im not sure if in N7 you have to check the option
Try the 2° option but take a look at this comment:

If thats true then try to flash 4.3 and install 4.4.2 by OTA, just select 4.3 instead 4.4.2 when you are about to flashing

Ok,
I flashed the nexus 7 2012 directly to the factory 4.4.2 using the nexus root toolkit, and everything is working fine without problems, at least for now.
The tablet isn't giving exchange errors, and doesn't hang everytime, but I only used it for some minutes, lets see how it works after some days/intensive usage.
Anyway, as I said, I flashed to 4.4.2 directly using the toolkit, and it worked without any problem
Thank You!
