Hi all,
I am a chef-newbie, trying to cook my first very own ROM. I am making many mistakes, some ROMS don't work at all, some freeze, etc. Is there a way to test a ROM without flashing it to the phone? It's a very slow and boring process and I am affraid that the memory containing the ROM cannot be overwritten for a unlimited number of times. Some kind of emulator, where I can put my ROM??? Or a completely different way??? How do yo do it?
Thank you for your advices.
an emulator would be really nice!
hope that there is one
no emulator that I've heard of, and yes, it would be lovely.
as for flashing, you should start to worry once you have flashed 100,000 times.
(flash memory can take a hundred thousand to a million read/write cycles before it gets near failing.)

I know i have seen this mentioned before but in running a search never found a definitive thread on it...so forgive me if this is redundant.
Its my understanding that the same rom build but one being loaded with as many programs as the partition will allow vs. the same rom build with most extra programs taken out should have no noticeable impact on performance as long as you use the task manager to only allow the same essential programs to load at bootup. the down side of a 'light' rom is if you want to add programs later it will not be installed in the partition with the rom....even if there is space..it will take away from storage space.
My question is, if my above assumptions are correct, why do people want light roms? why not have one loaded up with all that can fit...no matter if your talking 2.1 or 3.5 (3.5 giving more space for roms due to the partition being moved).
thanks
Why installing many non needed applications isn't a good idea in ANY PC?
Because..... startup loading .dll, services, reading BIG registry file, crowded windows directory slow down the PC, decreasing available resources and memory.
A WM6 ROM is a swiss knife! Many things, to answer to all user needs... but I have mine . SO you can chose the fast way, flashing a lite rom, of the hardest way (mine), flashing a FULL rom and stopping non needed services, avoid loading uneeded dlls... The same things the chef does before releasing a lite rom . This is the hardest way, you have to know deeply WM6 structure, using a light rom is the easiest way

My rom is really full, and isnt slower then light roms.
hehe!
There is a difference in available memory with the different SPLs, spl1.2 gives you more storage memory than spl3.5.
That said......
when a rom is loaded with programs it sometimes gives a user problems to install a new build of a said program that was loaded in rom. When you install a newer build and then try to uninstall it you might end up with a "hanged" device (this happened to me multiple times), and the only way to not see that wait cursor is to soft reset, and after soft reset, the program is still there in "remove programs", and if you try to run it after soft reset it won't run, and if you try to install it again you will get the message that the program is already installed and you have to remove it first and when you try to remove it again your device is stuck with the wait cursor again.........after all this, the only way to remove this program that you can't use anymore is to do a hard reset.
this happened to me too many times, this doesn't happen all the time though...some programs got installed over whats built in, like opera9.5 but I ended up with 2 icons in programs.
This is one of the reasons that kicked me away from full roms. I liked full roms before but after these incidents I find that lite roms don't/hardly come with those kind of problems, plus I get more space with spl1.2 to install a good amount of programs that I use regularly and still have more than 100MB left to install more programs that has to be installed to main memory.
Below are things I had said in another post and didn't want to rewrite it, so I just copied and paste (something my friend can't do on his iphone, ha, I still laugh at him about it)
Well really, Lite versions don't really bring much to the table except that it allows me to install only the apps that I need or want without having my programs folder looking like something out of a horror movie , eg. if I use the more robust SoftMake Office 2008 there's really no need for me to have MS Office installed, right?
Lite versions gives me an almost clean OS which gives me the "feeling" that my phone runs faster (even it it isn't running faster and just a subconscious feeling). Plus it installs faster .
Lite Versions are just the courtesy from the chef to us the people who wants the lite version, because the chef cooks in the apps that he wants, so for him to take out all that just for us is real generous....get what I'm trying to say?
It is nothing superior to the full, it doesn't carry the bells and whistles, its just what it is "lite". I have a plethora of cabs and only the ones I use. On a full install I hardly use 50% of the apps that comes with it....actually, I might only use 25%.
For me it all boils down to this......a lite version offers me the option of really customizing my phone, no additives, just the things I put in it.

Hi all, as you can tell by the title, I am a newbie to not only this site but also to Android & Linux too!
A little bit of a bio on what I've done so far (a bit long so please bear with me!)
I've had my HTC Desire (about 6 different handsets at last count) for just over a month, and as I have problems with the standard Orange HTC software, I read up and successfully rooted my handset, since this I have had no problems with the handset what so ever, and wont ever go back to Orange based software!
Now I have read up about 'cooking' my own ROM's, and spent some time on android.modaco.com, but I dont have the spare cash to pay for the online kitchen, and with a lot of research I stumbled upon this site (great site & info by the way!!!) so I followed the post on how to set up Ubuntu in VirtualBox (until the Java error and it needing root access or something) but anyway, I then saw the post about Cygwin and how to set up the kitchen and I did 'cook' a ROM, it was bassed on Pirate Rum's Android 2.2 ROM, so I run this through and added a few extra's but when it was burnt onto my handset and it rebooted, it did not work, the screen came up as normal, but I think I left out a launcher as I couldnt get to a home screen, no problem I thought so I then downloaded the 'PB99IMG_Bravo_HTC_WWE_1.21.405.2_Radio_32.36.00.28U_4.06.00.02_2_release_126984_signed.zip' ROM from the list of sites in the post about Cygwin, and precoded to modify this to my liking, also adding the Apps2SD package, all seemed to go well until the install was complete and it just got stuck in the loop of rebooting, getting the white HTC screen with the annoying tone and rebooting again.
It was like when I first rooted my handset and didnt partition the SD card & set it up per the guide on how to partition the card (512MB EXT2, the rest FAT32) etc... but anyway, I couldnt recover the handset properly, so I had to do the rooting procedure all over again, with goldcard, then set up Apps2SD, partition SD card before I could install ROM Manager to restore my phone to fully working order!
Please can you help a noob to be able to successfully 'cook' and burn my own ROM onto my handset please, as I am really eager to complete this so I can add new skills to my repertoire
Thanks in advance for your patience, help & advice and again, sorry for the mammoth post!
TIA, Arty.
Hi Arty,
Welcome to xda-developers. It seems you've already read up alot on android. Still I would advice you to read the top sticky posts, as they contain ALOT of useful info on "cooking" and android rom.
Oh, and try to refrain from creating new topics with every question you have. I know this is your first, but I'm just making sure you're going to be a good member.
Advice needed!
Thanks for the welcome NeoS2007!
I have managed to custom a few ROMS, but these have been ROMS that others have cooked and I would like a blank canvas so to speak!
The other day I did download a stock Android 2.2 ROM, but I think it was for the N1 or something because after waiting ALL FLIPPING DAY for it to download(guess the guys site speed was really pants) I flashed it onto my Desire but it didnt work, just was stuck on the white HTC screen for about half hour before I accepted it would not work!
I have also tried to use different boot animations (how DO you make these yourself?) made by others and use that on a ROM I have been fond of, but that dont work either
Also, how is it possible to make your own backdrop wallpapers for Android to add to your cooked ROM?
In short, the topics I need help with are:
*** Where to get an un-modded Android 2.2 ROM from that works on the Desire?
*** How to make your own custom boot animations?
*** How to make & add your own wallpaper to add to your cooked ROM?
Thanks in advance for your help, time & replies, I hope I can get the answers to the questions I have asked here!
Arty.
Hi guys,
First off, I'm a total newbie to custom ROMs, root etc - so whilst I'm considering following ChainFire's directions to install CWM, it makes me nervous... I did read all 20 pages of the thread, but am still left wondering about a few things:
1) Once installed, is that it? Have I voided my warranty? It states that you can still update firmware or re-install stock ROM, but I got the impression that it left a trace behind which Samsung could find. Is this correct?
2) Presumably before attempting this, I should completely back up my phone. But how? I can copy files from readable SD card (int & ext), but what about the 'hidden' parts of my phone?
3) Finally, how risky is this? I have been tempted to root for ages now (had an HTC Magic, then N1), but just felt my complete lack of knowledge (have been using Android for 2 years now and regularly read tech sites, but more from a user POV rather than dev) has kept me from attempting it. I know, bravery is the key! But is it really worth me trying it if I'm that lost in the world of dev-speak...???
In advance, I really would like to thank anyone who can spare me their time to help me through this...! I feel so out of my depth, yet am actually really comfortable with Android (since cupcake), so feel as though I should be able to get more from the OS.
Once again, thanks.

Hi, everyone. I'm new, and i just realize "rooting" will speed up my phone.
I'm totally newbie, i need a tutorial which have more details and attached file for me to help me out.
my phone is I9000M.
And the other question is: what is the definition of ROM, FLASH, ROOT?

Rooting
Rooting is the method in which the user gains 'root access'. Root access is a linux term and is used to define the abilities of the super user account, akin to the 'administrator' account in Windows. This account can modify and change anything on the OS it resides. So when your phone is 'rooted' it is not broken, you are merely in complete control of your phones OS, cool huh?
But what does this mean? Most people don't even realise they aren't in complete control. Well there are a few benefits to having a rooted phone, but there are two big ones. Custom ROMs, and apps.
Firstly, apps. Because you are now in complete control, you can grant apps super user access that require them to work. Such as taking a screen shot of your phone, taking a comprehensive backup of your important data, using the flash as torch light or enjoying an ad-free Android!
Custom ROMs
Firstly what is a Custom ROM? Well a ROM, is actually a colloquial shortened version of 'ROM Image' which in turn is short for 'Read Only Memory Image', and dates back to the cartridge gaming days. Remember slotting that thing into your sega mega drive? or your N64? Anyway, back on track, it's basically an entire OS in a file called an image. So a 'ROM' is a file with an OS in it. Now a 'Custom ROM' is a ROM that has been customised, simple enough, yes? Nearly every device comes with a 'custom' ROM on it, bar two phones so far, the Nexus One and the Nexus S. They are the 'pure' androids so to speak.
So for every phone, there is a ROM preinstalled, this is the ROM the manufacturer has usually developed for that specific handset, or a range of handsets. These preinstalled ROMs usually include a lot of junk called 'bloatware', essentially just apps and links that can't be deleted that you may or may not want. You don't get a choice! The beauty of custom ROMs is you can delete and add anything you like to them!
FLASH
Flashing is the method you use to put a Custom ROM on a phone. Flashable packages are zip files that can be installed by Flashing using a tool like ClockWorkMod.
Let me point you in this direction for your i9000 - http://forum.xda-developers.com/forumdisplay.php?f=748
Goodluck!
Hi everyone, I am a new member here and would appreciate any help regarding running a net program called “Starfall” on my Viewpad 7. I use this program to help teach my Grandson Maths and English, I should say that I am nearly 70 so not too up to date on androids so be gentle.
The problem seems to be with the Viewpad 7 (which I only bought two months ago) is that it will not support Adobe Flash Player. The reason I have been told is that the Viewpad does not run fast enough to operate Adobe for Androids latest version or any version.
I have tried to install an app called SWF (I think) but the Starfall program would still not work.
Is there any player which will work on the Viewpad 7 or can I download a different operating system and store it on the SD card.
I have seen posts by Amalgation regarding a ROM upgrade (I think) but could not really follow what it was about. Would this help?
Many thanks

Hi, been away and busy lately with Nexus 7 running Jelly Beans (4.1.2) and there isn't much going on around here - Vpad7 has been discontinued. Mine is still in great condition after almost 18 months, great for playing Angry Birds & introduction to tablets and Android OS.
Are you running stock Rom - I suggest taking at look at the EUv1.7 rom (ITE or non-ITE, depending on your hardware build) which support & run Flash Player 10.2 - it's very responsive and my personal Rom for 15+ months. For web browsing, consider using Dolphin Browser as it is work with Froyo.

Hopefully, this will get you started in getting your device to better run Flash for the Apps.
Thank you
Thank you for your kind reply, I am very grateful as a member in their twighlight years.
As i understand your reply, the link to the post dealing with downlaoding a different ROM is that this download will be into my SD card and upon bootup, the Viewpad will work for the OS in the SD card rather than the interal system. The proceedure does worry me as it seems easy to get lost but i assume if all goes wrong I can do a "factory reset" and get back to the "as purchased" system.
Once again many thansk

John, yes - I can confirm that running EUv1.7-LTE custom rom, and after downloading "Starfall" from Google's Play Store that the app will install and run, but it also FC (File Closed) or crashed.
You will need to go to the Development section of the Viewsonic forum here, follow the steps to root the device, install the custom recovery partition, and flash the custom rom - it sounded like you are new to Androiid, welcome but you need to learn how to do it and/or get someone experienced to help you do it.
On the other hand, with numerous Apps out there, you might want to take the easy route and choose some of the free Apps that do not require the use Flash Player undr Froyo OS, just my recommendation depending on your skills level & availability of help.
