Simple question. If answered in another thread, please give me a pointer. I searched, but couldnt find an answer. Here is the question.
Why do we have to revert to Stock 2.1 before flashing a custom ROM? Why can't we flash a 2.2 custom ROM over another 2.2 Custom ROM? And finally, is there a CWM flashable version of stock 2.1 with root and cwm pre-installed?
Thanks.
before a lagfix was adopted as "standard" by the dev community this was necessary to reset the phone file system to n unmodified state. Now that all the devs are using the same type of awesome lagfix, reflashing to stock isn't really necessary anymore, IMHO. I never do it anymore. I just do a wipe user data from my recovery menu and everything seems to work fine.
The answer is not simple.
You do not have to flash stock. It used to be more needed. Devs still say so, but I believe that is largely to problem shoot issues from the get go. Threads are cluttered with comments like omg my phone is possessed. Well what were you running prior, and what was your setup? If stock well we know what was what. If ulk kernel with ext 2 loop, then yes there could be issues
Flashing stock at this point is just as risky, if not more risky then flashing directly over. If something feels wrong and you can't fix it, flash stock\master clear start over
So in essence, we can flash fine over an existing ROM and if there are issues, better go to stock and flash from there. Am I right? Can you list the steps you take to flash a new ROM without going to stock? Will there be issues if lets say I flash a 2.2 ROM over a 2.2.1 ROM?
I.do this but it may be redundant
Backup apps
Dl rom
Boot recovery
delete cache
delete davlik cache
Flash rom
delete davlik cache
Boot
I never did flash back to stock. I failed. Odin would not connect.
But for you guys out there - there is a way to bring recovery menu, that's what saved me.
Remove SIM and SD card.
Power+VolumeUp = reboot from any locked state
Power+VolumeDown=reboot into recovery
Power+both Volumes=download mode, never worked for connecting Odin, I could go there from Recovery
So my sequence:
remove old backups
create new backups
download ROM
boot into recovery
flash rom
clear cache partition and dalvik cache (probably the same)
run fix permissions
reboot
I think for most new ROMs that take advantage of the updated 2.2.1 filesystems you don't need voodoo or any lagfix. Can't even remember the last time I used ext4 when using speedmod kernel and JS3/JS5 Rom. Makes it easier to flash new roms when you don't have to worry about corruption.
But flash back to stock clears out any unnecessary gunk that could cause 90% of Force Closes and random vibrates on boot
I always thought of it as installing a new operating system or a different version of. It. Cming from the same roots of the ROM or OS, you can just install a different, major update over it (Different ROM) and be on your way.
However if sonething is built differently from the start (Windows and OSX), you cant just install right over the other because there are problems.
I always start back at the beginning because it onky takes a few minutes extra and it makes the phone a whole lot faster; you clean out alk the gunk and unused folders and whatnot.
you definitely want to do a master clear if you do not start from stock, since there are some caches on your sdcard may ruin your new system.

Does anyone know how to do a Master Clear with Odin3? Or is there some other way we can do it without Odin3?
Thanks.

Hey guys, so I had MIUI since it came out and kept updating it every friday like I'm sure everyone else does that has it, but today I wanted to try out a Gingerbread ROM other than MIUI or CM7 so I went and tried to install Mosaic IV. I followed the tutorial on MobileTechVideos for installing it and when I got to the part where I had to install the zip from the sd card I did it and it got stuck at formatting partitions. So I waited a while, about ten minutes, then took out the battery and tried starting over from stock again. Then I realized that I was supposed to use a different kernel for Mosaic IV then the one Josh used in the video. So I downloaded that kernel and used that one instead of the one he used in the tutorial. And I couldn't get into recovery mode with it. So I flashed to stock again and redid the whole thing, this time I got into recovery and flashed it but it still got stuck at formatting partitions. So at this point I was like crap I have to get a different ROM. So I tried flashing Serendipity and that wouldn't install either. Then I tried MIUI again to at least get back to what I had earlier today, and I got an error while flashing the captivate-efsbackup zip in recovery. I have no idea what to do, all I want is to just get off of the stock firmware which im stuck with for now since I have to go to work in a little bit. If anyone can help it would be greatly appreciated. Thanks in advance
I had a similar problem, and the ultimate fix for me was this:
Flash back to eclair stock (which you did)
Master Clear (aka format internal sd - make sure to back up your stuff first!)
Install CWM (may have to go manually - renaming to update.zip and reinstalling packages)
Wipe dalvik cache and cache partition, as well as user data
Install a stable Froyo ROM (take your pick, preferably a full-wipe with no bootloaders)
Reboot to CWM and do a second dalvik/cache/user data cleaning
(If you're going GB)
reboot to download mode
flash stock GB (WATCH OUT FOR BOOTLOADERS!)
boot it up, let it settle, reboot to CWM
flash your GB rom.
(If not)
Go where you would go from a stable Froyo Rom.
That's how I got back from a messed up phone with GB bootloaders to a working Mosaic installation. I can't say it will definitely work for you, but it may give you some ideas.
+1 get clockwork recovery...you need to make sure the rom you are flashing is compatible with the version of CWR you are using.
For example a rom that needs to be installed with CWR3 you will need to install the zip presumably from CWR2. Pull the battery and reboot back to recovery - you should now be in the updated version of CWR. Then for safety sake - re install your zip.
Reboot and you should be all set.
I had lots of trouble going from 2.2 to 2.3. Flashing between 2.3 roms is very easy comparatively

so your saying that you went to a gingerbread rom straight from MIUI? if that's true it failed because you didn't have the gingerbread bootloaders before you installed the rom

I flashed the gingerbread stock rom and have it rooted with xcal's kernel, but when i flashed mosaic IV it got stuck at formatting partitions and i pulled the battery after about 15 minutes and then restarted my phone to find it stuck in a bootloop. So i had to start from stock again and now im back to gingerbread stock with root. I'm kinda scared to try again because it takes me like 30 minutes to get back to gingerbread stock with root. I think ill just stick with stock for a little bit
I just flashed to gingerbeard rom from cyanogen 7 (after odin flashing froyo)
from that i am always getting error like not sufficient space.. i am unable to download any app via market. i tried diff version. now i am using darky 10.2. please help me
when using old market.. the download not even starting
are you sure you flashed like u should?
formatted system and all?
my suggestion to you is:
format system, dalvik, cache.
download stock JVQ - http://hotfile.com/dl/122481899/943a689/I9000XXJVQ.rar.html
install it thru odin 1.8 with repartition.
after booting put ur rom on SD and go to CWM and flash it.
tell me how it goes and if it helps.
GL!
I installed Deodexed Stock XXJVT stock rom from here, and everything went well. Than I wanted to root it. I did that with this kernel CF-Root-XX_OXA_JVT-v4.3-CWM3RFS.zip, and it also went well. After that I wanted to "restore to factory settings" - format my user data. When I tried that, phone rebooted, than went to Android system recovery, and ask me to choose one of the options (see picture). I tried "wipe data/factory reset", but I got error messages from picture bellow. Tried again with same result.
Than I flashed phone with stock rom and stock kernel AGAIN. Tried to restore to factory settings, and 1. phone DIDN'T go to system recovery, and 2. erased all data WITHOUT any errors and with complete success.
Than I tried AGAIN (for the second time) to root with same kernel (again it went well). Than AGAIN tried to restore to factory settings (erase private data), and AGAIN problem mentioned above happened.
Now I have stock rom and stock kernel again. I need root for some things, but I don't know how to solve this problem. Could someone please help me with this?
Thanks.
hello
use odin to flash it see here
original rom xxjvt : http://www.techgom.com/2011/10/install-235-gingerbread-xxjvt-on.html
how to root it : http://www.techgom.com/2011/10/cf-root-for-gingerbread-235-xxjvt.html
-----
you must translate page to english with google chrome
You've already done a hard reset, so just install cf kernel again. Most instructions say wipe before flashing, you have still removed previous files etc
Sent using TCP/IP
Thanks both for quick reply.
@seghier
Thanks for these instructions. I did slightly different process. Maybe this why I got all these errors. I did use ODIN, but I flashed rom with "re-partition" checked (instruction says it shoudn't be checked), and also I used PIT while I am doing this and this instruction says I should do this without it. Check attachemnt picture for hw I did this.
Also, I did root with only PDA, and this tutorial says I should also PIT file included. See attachment for how I did this root.
I am a newbie so I am not sure if this could cause these errors? And did I do something wrong flashing and rooting phone my way?
Should I do this again following this two tutorials or not?
Also I am not sure what is DEODEXED means? Is there any differences between regular stock rom, and this DEODEXED one?
I just want regular stock rom and regular root.
oxeded rom is the original rom from samsung / deodexed is rom can be modified by users and you find in xda forums the difference
the method in photo is right
or you can install deodexed rom from here and the flash very easy :
http://www.multiupload.com/E9AT600ZUC
than use the files like see in image without pit or repartition
http://img707.imageshack.us/img707/1808/ppppas.png
Thanks, I will try now.
I still checked "re-partition" because I was using before DEODEXED, and now I am flashing ODEXED rom, so I thought maybe it is a different partition type. Is this ok? Flash went okay.
hello
when you find pit file repartition cheked automaticly
tell me if you success with flashing
Yes I did, thank you. But this problem with unable to restore to factory settings, after do root, still exist, even on ODEXED rom. It is deffinatelly some bug.
if you have problems you can format your sd card but first save all your files and data files using cwm : than create backup
you can try other deodexed rom from : s i9000 developement
i used the original deodexed rom and work fine
I don't have external SD card, just internal memory. Backup isn't problem. I wanted to delete all my personal data, but this error happenes. Did you try erase personal data AFTER did a root?
try this
settings ----- sd card and phone storage-------usb storage : format usb storage
and that remove all your files : music photos ...etc
-for hard reset try this : *2767*3855#
-factory data reset : *#*#7780#*#*
save all your photos and music ....
I already bring back some things, and also I managed to erased all that before doing root, so I won't experimenting anymore for now. Thak for your help. I will try this next time I want to clean my phone completly.
i hope that work for you
and deodexed rom more better because you can add new theme or launcher or flash update without limit than oxeded rom
good luck
Thanks.
try a new kernel
working now? please give a feedback ?
Like a wrote before. DEODEXED and ODEXED both work and I CAN restore to factory settings. After do root, it can't ba done anymore. I tried every possible combination, but result is same, so I guess that can't be done (which isn't so importante to me because I already restored to factory settings before apply root).
I didn't try other kernel (don't know either where to find other kernel), because I already installed programs, made personal settings, so I don't want again to wype all that.
If someone of you could try this it would be okay.
try semaphore kernel is very nice :
http://forum.xda-developers.com/showthread.php?t=1112908
use this application to install kernel :
https://market.android.com/details?id=neldar.sgs.kernel.flasher
and this application for save all your application to external card and you can restore it :
http://fr.appbrain.com/app/app-backup-restore/mobi.infolife.appbackup
--------
and don t forget to make backup with cwm
I am not so experienced about all this. What is difference between semaphore kernel and that other kernel I used for root?
Also if someone else could try this, who need to clean phone anyway, because I just make everything to work OK, so I don't want to experiment again.
I want to Flash Team ICSSGS [Android 4.0.3] (Link to ROM Thread) but I am not for sure what Bootloaders or Kernel I need to use.
I currently have:
Firmware Version: 2.2
Baseband Version: I897UCKB1
Kernel Version: 2.6.32.9
Build Number: FROYO.UCKB1
In general, the Gingerbread bootloaders are preferred with any of the ICS ROMs, because they are more ubiquitous and can be used with virtually any version 2.1 thru 4.0. Kernel-wise, the ICS ROMs come with a kernel, and your only other option is Glitch v14 beta right now...but mostly, you shouldn't need to worry about flashing anything beyond what's in the ROM itself right now.

So that ROM I listed in my OP comes with its own Kernel?
And is there a particular Bootloader I should use?
If there is, may you please link me to it?
Hey im currently running the ROM you are asking about. To answer your questions you have to be on the gingerbread bootloaders. You can flash those using odin, or since there is an official update out, use Kies mini to update your phone to gingerbread and that will flash the bootloaders for you.
About the kernel, the ROM you posted includes a kernel in the .zip and when you install the .zip it will flash the kernel for you. Its a fine kernel and works great so dont worry about changing it unless you have problems.
Here is the link on how to flash the bootloaders using Odin. Its not a hard process and pretty safe so let us know how you come out on the other side!

froyo will still boot. GB BL are backwards compatible and the ISCSGS script should allow it to flash over any ROM

Yes, Froyo will still boot. If this were a layer cake it would go something like bootloader, kernel, rom. So basically, your bootloader has nothing to do with your kernel or your rom but it is at the bottom layer of the boot process. It does effect which ROMs you can use though as gingerbread and ICS roms require GB bootloaders. So flash the bootloaders, you will still be on Froyo. Update to GB. Root GB. Place the ROM on your internal SD and then flash it. If you run into any problems check the common problems page found on the first page of the SGSICS ROM.

First, if you want to keep any of your apps or contacts backup those as well using Titanium Backup. Make sure to backup to the External SD card or make a copy of the backup somewhere other than the phones internal SD.
Second, you dont have to wipe data/factory reset before you flash. This is only if you have the problem of a bootloop when you try to install. I had this problem and when I did the wipe data afterward it fixed it immediately. So follow this:
1: Boot into CWM
2: install rom
IF you have an issue with a boot loop at this point
1: Get back into CWM using the button combination
2: Wipe data/Factory Rest and Wipe Cach

one more question, i understood about data/factory/cash, but dont i need to format system before flashing new rom? i thought its always better to do before new rom flashing?

I think this was true when flashing older roms. When I flashed that ROM I did not format system and it worked fine. Let me know if you have any problems when you flash.

IMHO the best way to go from gingerbread to ics 4.0 is to
- in the development section download stock kk4 without bootloaders, unless you dont have them http://forum.xda-developers.com/showthread.php?t=1300843
- then download a kernel of your choice probably cornkernal and put it on your internal sd card
- download ICS latest build and gapps and put them on your internal sd
- oneclick odin the stock kk4, let it boot up completely
- power off and install kernal via odin without aut reset
- boot into recovery, factory/data reset, clean cache, clear dalvik, install latest ics, then install gapps right after,
- reboot system and youre done.
IF you want to go back to your other rom the simplest way is to just kk4 fresh install, install kernal via odin, then isntall your rom.
I always keep all my contacts synced with gmail, and titanium backup any game data or app data i need, and reinstall apps through the market.
hope this helps

I gone ahead and flashed ICS onto my phone. It is working good but the Hang up button does not work. In order to hang up, i have to lock it and unlock it.
Now i did a Backup of Froyo from within CWM. if I do have a problem, can i go to DWM and restore the backed up Froyo?
