Hello, people of xdadevelopers! I'm new here and keen to learn up on custom Android roms. Sorry if i sound really noob or am doing things wrong in this forum, but... everybody has their own starting phases right?? ^^ Please guide me where I'm going wrong...
Anyway, I'm from Singapore and i own a SAMSUNG GALAXY BEAM GT-I8520 (rare and unheard of phone released only in Singapore x.x). I won't elaborate much, but basically I'm kind of still a student (therefore no money to buy other phones) and my mobile plan is left with about 11 months to go before i can renew my plan and select another phone for a cheaper price... I don't really like my phone because the moment Samsung released it, they decided to stop updates because there is not enough users of this phone so I'm stuck with 2.1 eclair. It also has a slow 500/700mhz processor and lags like he**. By the way, it was released around July 2010 at the same time with the Galaxy S, and they have really similar specs, that's why i posted in this area of the forums.
So, i was thinking of switching over to the MIUI rom which i desperately want... and i decided to follow the Galaxy S I9000 (because they are sister phones!) tutorials to flash over to MIUI in hope it would revitalise my phone, stop the laggyness and crashes, give it a new look, allow me to use features that i miss out in froyo or gingerbread!!
I can understand most terms and softwares about flashing... been researching for a few days... and i found this guide
http://forum.xda-developers.com/showthread.php?t=1101601
which tells me to replace my bootloader with a gingerbread bootloader through ezodin, then boot into recovery mode which is the custom cwm recovery, and from there straight up install my rom that was placed in the sd card, and walla i get my MIUI. I assume that the bootloader will give me CWM recovery because the guide doesnt tell me to get it through rom manager. I currently have the base google stock recovery, so question <1> do i have to install cwm recovery through rom manager first or will the gb bootloader give it to me once flashed? and question <2> i've tried to install it through rom manager but it didnt work the first try (i chose my phone model as the S) and even erased all my apps and data :S Is there a way to go around installing clorkworkmod? I understand my phone isn't EXACTLY Galaxy S, but they're similar...
Also, another problem i face is that i DON'T have the 3 button shortcut to recovery mode or download mode. I'm following this tutorial to try repair it, since I've heard a batch of Samsung galaxy s have flawed recover and download modes that can't be accessed by the 3 buttons. since the two phones were released around the same time, it could be that the galaxy beam was affected also. Everything is fine going through this tutorial (even getting to download mode trough ADB is fine), problem is i get stuck every single time in ODIN at SetupConnection. Question <3> any freaking idea how to solve this? I've gone through google and searched through this forum... Now i don't know what to do and don't dare try anything else or other flashing unless i fix this 3 button shortcut because i know i can only access recovery or download through ADB REBOOT RECOVERY / DOWNLOAD and the phone has to be plugged in, turned on, booted into android, and in usb debug mode. the ADB command won't work if the phone is off and i'm worried the GB bootloader will stop eclair from loading.
This leads to the question <4> if i decide not to follow this repairing tutorial and just flash the gingerbread bootloader up front, will it give me the 3 button shortcut boot? because if i am not able to load the eclair rom with gingerbread bootloader, and have no 3 button shortcut, i will not be able to boot into recovery to install rom and wipe data and cache etc. Also, if i flash the gingerbread bootloader, can i still load into my stock eclair rom? If i can load into the stock eclair rom, then i don't need the 3 button shortcut, i can go straight to doing usb debug and the ADB command again after flashing bootloader and rebooting to go straight into recovery and installing MIUI.
Question <5> What about gingerbread bootloaders that can backtrack and load froyo roms and eclair roms? Do these exist? Where to download? If so, i can load into my eclair rom and use ADB for recovery mode, eliminating the step: repairing the 3 buttons.
Question <6> Also, i noticed the guide didn't speak anything about kernels etc. From what I understand about kernels, it is the architecture or system between the hardware and the software. People can tweak kernels (leading to custom kernels) for different and maybe even better sound and video etc right? But the guide doesn't say anything about installing a custom kernel, so am i supposed to keep my current Zues kernel from Samsung, or is a custom kernel recommended by MIUI ALREADY provided in the zip folder i downloaded from here? (the I9000 one) When i flash this zip through CWM recovery, is the kernel changed together? Does this apply for the bootloader also? Is the bootloader supplied in the zip and flashed together at the same time? if everything, (rom kernel bootloader) is flashed together at the same time then i can eliminate many steps and just work on installing CWM recovery through rom manager. then use adb to boot into recovery and flash that one simple MIUI zip. no need for 3 button boot...
Question <7> Is there another way to get MIUI to install on my device without so much hassle? haha..
Thanks for the trouble, I know it's a lot of questions... Please answer whatever you can
umm, almost a 100 views... but no replies? :'(
I'd never heard of it until this post, I looked at some specs and they're quite significantly different to the SGS's ones, smaller screen and completely different processor(which is most important(TI OMAP 3440 720MHz in the Beam and Hummingbird S5PC110 in the SGS)). It's a completely different phone, don't even try to install MIUI for the I9000 on it unless you don't mind your phone being in a bricked state. I may not be right but it's my strong opinion. Here is the Xda wiki for it: http://forum.xda-developers.com/wiki/index.php?title=Samsung_Beam Which shows how to root and then OC it which may increase performance. And if you like the Miui look there is a look a like launcher floating round if you search. Good luck
true, they aren't exactly the same. the processor is definitely different, but i think MIUI was made for performance, which fits well with this lousy processor haha. screen shouldn't be a problem, most softwares fit to screens automatically. I've already Rooted and OC'ed it but its still slow.
Is there any way to flash everything at once, e.g. kernel rom everything flash together at the same time using ODIN, then maybe i will reboot and see if the MIUI works... The problematic part is the 3 buttons download mode. I'm willing to flash everything at once then see if i'm lucky and MIUI will work for me. I'm not willing to flash just kernel or etc, then can't get in to download mode already because phone cant be booted, thus cannot install ROM...
Does anybody know exactly what when flashed into the phone gives me the 3 button recovery and download...?
I also realised something in the wiki link u gave me...
Power+Menu+Volume Down -> Soft Reset
Power+menu+Volume Up -> Ready for Flash Screen
Could this be my recovery and download...? I'll try later.
I'll try and give you an example, the Galaxy SL or the I9003 came out the start of this year as a replacement for the original with the only difference being the chipset and display type. Quite a few people have got this phone and have being trying to get Miui to work on it hasn't happened. The I9000 kernel for Miui is made for the I9000, it only works with the Hummingbird chipset, end of story. I'm not stopping you from trying but expect the most likely consequence to be the phone dead, not running Miui.
Wow, if the I9003 which was even closer (spec-wise) to the I9000 can't flash I9000 MIUI, then my I8520 won't make it... :'( I understand what you mean, any kernel made for I9000 phones, even custom user-made ones, only work with specific hardware, like that chipset, unless that kernel some how is clever enough to work with my hardware, or probably just lucky enough to be compatible with my chipset.
I didn't know the software had to confirm so tightly to the hardware... I'd always thought software would automatically work with basic hardware, albeit there would be some issues and glitches, but at least it would still work. I thought maybe it would be possible to keep my Zues kernel, and just flash the rom, and let the rom use my kernel.. It wouldn't be very optimised because they weren't made for each other, but at least with a few bugs, still usable... But now I know my Zues kernel works with my hardware but probably wont work with I900 MIUI unless it was coded for my phone... Though, if my phone does have the same chipset and gpu, maybe it will work?
Seems like I'll have to continue to use this lousy unsupported phone :S
Thanks for your help
Hi guys,
Basically I would like to install the ICS rom on my Galaxy S i9000 but have absolutely no knowledge of how to do so having never installed a custom rom before. Looking at the 'tutorial' for installing ICS leaves me just as clueless as it seems the individual steps require a decent knowledge of knowing what you are doing!
Also, I have discovered from attempts in the past that my Galaxy is one of those that is unable to go into download mode so that is another thing that I need help with (the link to the thread for the solution to this problem in the Galaxy FAQ is dead).
So yeah, any help much appreciated or even a point in the direction of the most thorough guide there is.
Cheeers.
Well, before you do anything you need to enable download mode. Think it's a case of enabling USB debugging and then adb, although I never had to do it.
Secondly you should probably stick a stock gingerbread rom on with odin.
Flash a kernel with odin.
Flash ICS
Flash ICS again.
Going straight to ICS with very little experience of custom ROMs may be a bit difficult especially given it's alpha status.
my phone also had the lock on the Download mode, seem like some service provides disable the feature to "try and prevent" people to flash custom roms as this voids warranty in South Africa. I found a fix on Google but cant remember where.. so if you dont get it right... some guys made a homemade jig here is a link on how to make it...
http://forum.xda-developers.com/showthread.php?t=819551
and when flashing a custom rom its best to follow the roms tutorial and usually there are post regard similar issues that could be encounter in the process. so the search function ends up helping alot instead of having to read thru 100 pages lol
its all new to us in the beginning then it just becomes second nature lol
i recon this is a nice tutorial to use
http://www.theandroidsoul.com/android-4-0-update-for-galaxy-s-i9000-custom-rom/
even has a method to return to stock

1st u did not say what stock firmware u ve, If u ve updated with kies then u should ve download mode, i ve exactly the same problem. Once i updated from foryo to gingerbread i ve the 3 button download mode but still no recovery, u might never get it but dun worry u can still flash custom roms.
Here's what u ve to do, upgrade to stock gingerbread 2.3 with kies then flash cfroot kernel with odin,u'll ve recovery n then flash what u like...

Josh. This is NOT a rom which you should pop your cherry on. It is buggy, not very fast and you need a good working knowledge of how to recover a soft bricked phone. If you cannot get into download mode, you would be foolish to flash ANY rom. There is a fix, search xda.
I admire the size of your swingers, but would recommend you gain a little more flashing experience.
However, good luck if you do decide to flash - there's plenty of help here if all goes wrong.
i "popped my custom rom cherry" on ICS build 12 i screwed it up when trying to go for build 13 but i found this tutorial http://forum.xda-developers.com/showpost.php?p=14273101&postcount=1
i installed the latest gingerbread kernel then the rom files and it was fine ater that and im just about to put build 14 on now so dont worry to much about it. Ive never got my phone to a state where i cant fix it, so if me a supernoob can recover a brick just about anyone could
I'm hoping someone here can help in explaining this because this is something I've NEVER seen or heard of before and in theory, shouldnt be possible but i'm seeing it with my own eyes!
I'm (about to) purchase a slightly used Samsung Galaxy S CAPTIVATE model (SGH-i897) at least that is what the "boot up screen" shows.. I KNOW this is the Captivate.. i've seen the physical differences between it and the Vibrant.. they are basically the same phones hardware wise but do have a different physical appearance on the outside.. the Vibrant's model is GT-i9000..
now when I go to the "About screen"...the model shows the GT-i9000! How is this possible? I'm baffled because I know that i'm actually looking at a CAPTIVATE and the boot up screen shows the correct model number..but the android os (which shows the gingerbread 2.3.5 model in the about screen) is showing the model number as the VIBRANT.. gt-i9000, on the same phone!
I want this phone and was about to buy it but i'm thinking this could seriously cause problems when i go to root and mod it as the conflicting model numbers could create problems with the proper files and processes i'll need to follow when doing the root/mods...
Has anyone heard of this or can explain this because I am STUMPED!
THanks
ok, it appears like a custom Kernel was used cause this conflict. Make sense?
I looked at the About screen again and the KERNEL VERSION looks like something that is NOT the stock kernel. It states:
2.6.35.7-I9000XXJVT-CL617736
[email protected] #DarkCore_4.1_JVT_C
this has to be a custom Kernel right?
This phone must have been rooted and mod'd at some point (the seller didn't know and thought his cousin only unlocked the phone).
I assume a custom kernel that likely is typically for the Vibrant GT-i9000 was flahed with or without a custom rom to this phone and that is why there is the conflicting model numbers... this make sense?
Normally that wouldn't be good idea to use another kernel or rom for a slightly different model of phone but i guess it worked..
I would now like to confirm that this is the case and if so, that it is obviously ok..cuz the phone is working fine.
Should I now wipe the phone back to stock rom/kernel? Can I? if I want to do more mod'ing on the phone anyways.. different kernels and likely update os to ICS 4.0
Thanks for any help on this and hopefully this all makes sense now and explains what i'm seeing
Many of the custom builds for the Captivate are based on I-9000 framework. DarkCore is one of the custom kernels. This phone has been flashed. If you prefer a stock Captivate firmware, there are ODIN One-Click programs in the Development section that will put you back to an "Out-of-the-Box" state. Then do some reading if you plan on shopping around for different roms, as there are several different sets of bootloaders among them and a bootloader mishap is a surefire way to brick this phone.
Happy Flashing and good luck! Welcome to the Captivate!
The vibrant model number is T-959 or some ****..I9000 is the international galaxy s. The original.
It is really easy to switch what is displayed in about phone...it's all in the builds.prop located in /system
You can open that up with a plain text editor and change any instance of Gt-I9000 to sgh-I897 and Viola...
But as mentioned above, flashing to stock with Odin/heimdall will get you back to stock.
Btw what does "build number" say in about phone? Cause that is the name of the ROM that was flashed to it.
Build number says: Mosaic 8
So that is the custom rom that was flashed to the phone I take it?
Ultimately I dont want to go back to the stock rom/kernel but want to definitely flash to OTHER custom roms/kernels. With that being said will I have to go back to stock on either rom or kernel FIRST before doing another change?
I'd like a kernel that will allow me to play with some overclocking and the rom(s) can be one of many.. preferrably I want to put ICS 4.0 on this
Can anyone give me the links to the best info/tutorials to flash the kernel/rom's to do so on this phone?
As said, the actual phone is an unlocked and rooted AT&T Samsung Galaxy S Captivate SGH-i897 but has been already flashed with custom rom kernel as follows:
Model Number
GT-i9000
Firmware Version
2.3.5
Baseband Version
I9000UGJK4
Kernel Version
2.6.35.7-I9000XXJVT-CL617736
[email protected] #DarkCore_4.1_JVT_C
Build Number
Mosaic 8
Thanks
M8 is a great custom rom. You shouldn't need to flash to stock before flashing a new rom. Just follow the steps in the first post of each rom you want to flash. A good ROM to try next would be Mosaic 9
yeah...i hear great things about mosaic!
Thanks..i figured it was a good rom..i play around with it for a while.. it also came with the custom kernel from DarkCore..
I'm fairly new mod'ing rooted phones and all that so I'm curious if I can install a different custom kernel on this Mosaic 8 Rom and if so, what's best way? I want to use one of the many on this site that allow for oc'ing...is it ok to replace the Darkcore Kernel that came with this rom to any other or not?
THanks
hey buddy, i happen to be the lead developer for mosaic.
you are more than welcome to change the kernel, the best way to do that would be in cwm recovery...which can be accessed by holding down on the power button and choosing recovery. or by powering off and holding vol up and power til you see the first splash (that should actually say I9000) then let go that will boot into recovery.
if you see an at&t screen at all the its vol up AND down AND power.
as said above i have updated mosaic, and the latest version includes a kernel that is overclockable already, this one to be exact the .tars in post 1 are for use with odin. post 2 are zips to be flashed in recovery. ater the kernel is flashed it will install an app called semaphore, in there are a bunch of options including oc up to 1300Mhz
that being said...FIRST I would play around with it some more and get used to it WHILE DOING SOME RESEARCH AND READING...i mean you just got the phone...get to know it take her out on the town before you get her all nekkid and vulnerable
THANK YOU SO MUCH for this reply! I was just trying to get into recovery mode and I noticed this phone was allowing me.. this is due to the rom/kernel on it..but you're post with the info WORKED! I was about to start doing a bunch of stuff to try and fix.. THANKS
This whole double splash screen is very new to me with it showing the phone as TWO different models..
I see you have the new Mosaic 9 out..and that's the one you're takling about i take it? and it comes with another new custom kernel that will allow for oc'ing too? sounds good..and 1300 is more then enought.. I'm happy with 1.2 if I can.. dont need to get crazy and try for 1.6 like some..
Just follow the steps on the main page for that rom and all should be good? What will be the easiest way for me to flash to your new rom/kernel? Can I do it from a rom manager or use sd card or internal mem? Any help on this is greatly appreciated! Thanks again for posting a response to my concerns!
btw can i just update this Mosaic 8 rom to that new custom kernel you're talking about or do i have to update to the new Mosaic 9 rom first?
You can flash that on 8.
Don't ever use ROM manager, it doesn't work right on the galaxy line.
And whenever sdcard is mentioned, that is the internal sd, cwm does not flash from an external sdcard.
To flash mosaic 9 over 8 just put ROM on sdcard, boot into recovery, wipe data/factory reset, then go to install zip from sdcard, choose zip, and find the ROM you just downloaded.
Flash the kernel the same way, just don't do the wipe first.
The ROM flash will wipe all your apps, the kernel will not, use titanium backup to backup your apps, then restore them after the flash. Again only needed if you're flashing the ROM and you can flash the kernel on the ROM you have now,
but a backup is a good idea before any flash if something were to go arwy.
As for the 2 boot screens (and the different button combos for recovery, btw download mode is vol down and power), is because the phone has I9000 bootloaders, which is the first splash you see, the second splash is the kernel, both darkcore and semaphore use the same splash the one that says sgh-I897. some kernels use a custom image there instead.
But again, i urge you STRONGLY, PLEASE read, and understand completely what it is that you want to do, and more importantly how to fix a situation that doesn't go as planned, BEFORE you start flashing stuff. Please.
Thanks again bud this is all so helpful. I already downloaded your mosaic 9 zip. Quick question..do i have to format my sd card a certain way first for the update to work? on past.flashes on different phone certain.partioning had to be done on the sd card in order for the update to work.successfully.
Thanks n looking forward to this mosaic 9.

Nope, you're good. Anything that was needed, which was flashing gingerbread bootloaders, has already been done by the previous owner.
Thanks again bud. That last question was pointless cuz i read back again and u mentioned that the sd card stated is always internal and not external..so obviously i wouldnt need to format n partition etc. Thats a bit newer for me well on this new phone anyways. Used to using ext card in past.
As of now ive only updated the kernel to the new one and not the whole new rom...yet. Will play around with it for a bit. The oc was very easy and working just fine.
Btw any plans to do this mosaic rom on ICS 4.0 at all? Or maybe there is one u could recommend? i really want to check it out as so many are "raving" about the new ics os and that it the best by far, etc. Whats your take?
One other question about the flashing from the internal sd now, hope this aint silly but if the zip rom file is saved to the internal mem and im doing the usual data wipe/factory reset wont everything get cleared.including the rom file itself and then not find it when i go to do the update?
and again thanks for all the info, still a bit of noob when it comes to the phones side of things but fyi im definitely a techie when it comes to the pc hardware, software and networking side. Take care
Sent from my GT-I9000 using XDA App
Data wipe/factory reset only wipes the /data partition. Leaving all others including /sdcard intact.
Data factory reset clears (/data, /dbdata or /datadata depends on the ROM you are on, /cache, and /mnt/sd_card/android.secure
Definitely gonna wait a while before flashing any ICS4 roms as still too early and lots of bugs to workout. Im hoping u guys eventually come out with an ics rom cuz this mosaic 8 n 9 are damn good and high quality and read a lot of good things too.
Sent from my GT-I9000 using XDA App
So the bootloaders, when are they input or changed? Is it a seperate update or do they typically come with a rom or kernel? So the ones i have now with the dual splash screens (gt-i9000 then sgh-i897), will i keep those if i wipe and flash a different rom or will a new set of different bootloaders come with most other custom roms? I still dont fully understand that yet and would prefer to mess with them as little as possible cuz i know how important they are and thats an easy way to mess up a phone.
Another quick question i have is about the Captivate phone itself...i know all the specific hardware specs and its states it has 512 ram outside of the 16gb storage/2gb internal rom but why can i only find spec screens that show my phone having 323mb of ram and of that most of it is used up all the time even after a fresh wipe and flash of the mosaic 8 rom ane nothing new installed? Does this have something to do with the rom itself or am i missing something? a little puzzled by this. Part reason i upgraded to this phone was to get better hardware and have more memory cuz i like to eventually install a ton of apps but im thinking i could quickly run into issues with the numbers im seeing. Any thoughts on this? Thanks
Sent from my GT-I9000 using XDA App
Bootloaders ate only flashed with a pc flashing program such as Odin or heimdall.
The second image may change, that within the kernel itself, the first image will not.
As far as storage space goes, you have 16gb on the entire phone. 2gb of that is for user apps. About a Gb for the system, and about 13Gb on the sdcard.
you do have 512mb of ram, but some of that is always used by the system leaving the user with 323. And THAT being mostly used up is just they way Android handles memory. It keeps recently opened applications loaded in memory so that if you wanna access it again it will open much faster than having to reload it. It will also kill off apps as the memory load grows. Put simply: free ram is wasted ram.
Just got this tab, and want to upgrade it from the crappy Verizon firmware. Would like the advanced features and root, but it must be stable for work and it must do 3G and/or 4G.
Apparently I have to install a ROM that is specifically for the SCH-i800 and not for the P1000? So how do I identify which ROMs are suitable?
I used to use CM7 on my Nexus One and now use MIUI which I think is great. Experiences on either, or some other flavor?
I am aware that ICS is available, but have the impression that it is not complete or stable. So I'd just as soon stay with Honeycomb or maybe lower as long as it can be relied on.
OK message received, there is none.
This matches my research. CM9 is shot through with bugs, and MIUI development is dead. No other contenders.
So I guess I stay with the factory firmware, root it, remove the crapware and set up security.

UGH, thank you JT. I am having a helluva time with this thing.
Trying SuperOneClick, but it does not recognize the device. No one says, but I suspect it depends on ADB. ADB apparently does not have the drivers for the SCH-i800, and I've no idea where to get them.
The Samsung sync software would not install in my XP running in VirtualBox -- drivers failed to install. So I plan on just putting files on the SD in another machine since I run Debian exclusively.
And there doesn't seem to be an alternative recovery like Clockwork or Amon Ra, but maybe I'm wrong.
Pretty much given up on flashing any better ROM, although I know you've done some good work, maybe for CDMA.
I'll check out that more applicable forum.
I also have the SCH-I800 from Verizon and the only ROM that I found that works with barely any issues is the GB 2.3.5 Galaxy Cube 3. You can find it here:

If you have any questions or if you find any new working ROMS please let me know. Good luck.
I got a Samsung Galaxy Tab from someone that is doing some weird stuff.
First off its force closing a bunch of apps when it first starts up and when in use.
Secondly when I make changes to the tablet and restart it those changes revert back to the way they were.
And the third thing is that when I try to reinstall the stock rom or use other third part roms the problems still exist.
I am kinda experienced with rooting/flashing roms as well as using adb and clockwork mod but unfortunately I think this device was rooted by someone that didn't know what they were doing and screwed something up... anyone got any ideas?
