Upgrading Darkys V8.0 to V10.1?

Hey guys i've read all the instructions and it seems fairly straightforward, flash with odin first to Ficeto and then use CWM to flash it to V10.1..
Problem is, I'm already on Darkys V8.0, I have no idea where to start? Do i need Ficeto, do I just backup all my **** and then flash it? Will I lose apps?
So lost.
Cheers boys!

Firstly wadever u do backup all ur wanted apps
Secondly disable lagfix before flashin new rom( nt sure if its right)
Thirdly dl ur new rom and put on sdcard not external
Fourly go into recovery mode install zip from sdcard than select the zip wait for it to install
When finish go in and restore all ur apps

I never enabled any lagfixes though?
and how do I backup my apps?

Also guys what is this JVH and JVK stuff?
Is Darkys Gingerbread V8.1 with Kernel 2.6.32.9 ([email protected] #62)
appropriate to upgrade straight to V10.5 like the above user has said?
I've already read the rest about uploading to SDCARD then booting into CWM and flashing, just need to know the rest!
Thanks guys

V8.0 is bases on Froyo (Android 2.2.x), V10.1 on Gingerbread (Android 2.3.x). So DON'T flasg directly from 8.0 to 10.1. Flash any stock-firmware WITH bootloader first (I think the best way wouls be to use Ficeto's but I'm not quite sure it contains the bootloader). Them after installing the stock-ROM you have to root your phone (just flash another kernel) and finally flash 10.1 with CWM and you are done.

[Question] Help needed and advice regarding upgrading my firmware please.

Hi everyone, I am brand new sgs owner and first time smart phone user and I upgraded my phones firmware on kies to 2.3.3 / baseband xxjvo / build number gingerbread.xwjvh
I been talking to a few people that have got 2.3.4 and cyanogen mod 7. And I really want to get one of them because my battery life is pathetic on 2.3.3
I have an idea how to do it (I have watched alot of tutorials) but what is confusing me is all the different downloads like cwm and speed mod, kernals, ROMS. All these terms are driving me mad as I dont know if I need to flash this stuff first to upgrade the firmware.
I have been told I may or may not need to root my phone to make it all work because of the current firmware xxjvo 2.3.3?? So what do i do?
Can I just flash a new firmware on via odin? or do i need to flash diff kernals or clockwork mod or speed mod what ever they are to make it work properly.
Im sure its all easy enough once its understood but I cant find basic explanations for all these terms.
I really dont want to mess up my phone but i know I can get this done once i know how.
So could someone that knows please tell me once off, what do I have to do to upgrade from gingerbread 2.3.3 xxjvo to something better like cm7 or 2.3.4.
Do I need to root first? install CWM or speed mod or whatever.
Also what is CWM and speed mod. are the roots?
Sorry for not knowing anything as i said its my first smart phone and I want to get to know how to use it to its full extent
Will greatly appreciate any advice/ help given.
If some ones going to help me could they post the links to the downloads that i will need.
Thanks very much

1.its simple root ur fone first via odin and then flash the voodoo/fugumod lagfix(incase ur experience any lag)
2.Download Rom Mgr premium and download (cyanogen mod7 ,nightlies or watever)
3.Take a backup using Mybackuppro or titanium backup before u flash cm7
4.Go to Rom Mgr Premium and then install the rom of ur choice and also make sure u check GAPPS(if u want gmail, market an all crap)
I m a newbie 2 Galaxy S myself, but i have quite som experience on rooting other fones

Thanks for the reply but what is rom mgr? and must i pay for it if its premium
And what is the download for the correct root I have seen a thread by chainfire with hundreds of root downloads but I dont know what one to use.
Is a ROM the same thing as a firmware?

Do I still need to root the phone before I can flash cm7 from sd card? Do I put it on internal or external sd card? And If so what root do I use for my particular firmware

Anybody? ? Someone must be able to help me

Here are some posts I think will help u find some answers,

Thank you for the reply. Is cm7 a custom Tom?
How safe is it to use a custom rom instead of a Samsung rom.
Can some one tell me is there a particular order I need to follow to upgrade my phones firmware.
Like root then something else followed by the firmware.
Could I upgrade from xxjvo without rooting?
Again sorry all the questions I feel like a dumbass.
Thanks

Double post

Again sorry for being persistent but could someone give be a step by step quire to upgrading my current firmware xxjvo 2.3.3 to something better for battery and better radio signal.
Must the phone be rooted first? Must I install anything else before or after the new firmware
Thanks

Hi, check out samfirmware.com to download stock 2.3.4
I'm on the newest jvr, and my battery is good.
It's also flash manuals there for how to use odin.
thats the safest!
If you want root permission, you can flash cfroot kernel after the rom.
Edit: i'm on the oldest 2.3.4 jvr, looks like it came a new relese today.

Is a specific ROM needed to run a different firmwares? or vice verse?
If I flashed 2.3.4 does that mean I have a new ROM or new firmware or both?
thanks

Pls do refer my previous post for upgrading to 2.3.4 GB roms (2)
2.3.4 roms are way better for battery. There are some light weight roms with excellent battery life eg SURFACE,Matrux rom, Juwe's Smart Edition(My Pick) etc
You dont need to be rooted to flash a custom rom via ODIN.
CM7 is a custom rom and I would recommend it only if you know what u r doing. Its not very advisable for a noob (imho).
There is insanity cm7 034 with gb boot loaders [ROM] insanity CM 034 [16.08.2011] - Multi DPI But its in heavy dev stage. Pls go through their thread before flashing it.

Back up your stock gingerbread rom

Hello,
first a brief intro...i am not an android developer but I am a user and I love the OS.
However i have had a little trouble with the small issue of backing up stock ROM so that i can have the freedom to tinker with any custom ROM possible knowing that i can always fall back to my stock ROM if I don't like anything or something doesn't work.
I have the original ROM so i can flash it back whenever but not everyone has access to their stock ROM. so you must make a choice that once you flash a custom ROM, you cant go back.
So i am calling out to all the nice developers in the house...
1. Is this possible. is there a way one can do a backup of the stock ROM in the galaxy mini?
2. If its not possible at the moment, is there anyone willing to work towards ensuring its possible?
Like I said, I am not a developer but i could help in any little way i can to work with any willing developer towards achieving this.
Thanks.

yess is possible to backup your rom juste install ROM MANAGER and clic on backup is simple you can find it on android marcket ^^

I would not personally suggest Rom Manager since there are a lot of cases here that it bricked the phone. It is possible to backup your stock rom with cwm recovery. The problem is it can't be restored via the same recovery. This is a limitation of cwm. So Odin is still the best option to restore stock roms.. I do hope that restoring stock roms can be made possible thru cwm..

I have tried ROM manager and it doesnt even recognize the cmw recovery already installed. it requests to install a custom recovery and the SGM isnt listed among the supported devises so that wount work.

Have you actually backed up your stock rom using cwm?I have tried and each time i get an error that it couldnt mount the /system. And am seeking assistance to develop a means to back up and restore Stock ROMs in SGM.

with custom kernel with suport ext4 and convert rfs partition to ext4 partition you can backup your stock rom.
only need flash custom kernel. after that you can backup the rom.
galaxy S user have CF-root kernel for each rom. CF-root do this and root your phone and install CWR.
but for mini no any CF-root kernel

.i have changed my CWM by another one find here with godell thread I use "CWM5028.zip"

Dude, don't you try Rom Manager, it may brick your phone. CWM can't make stock rom backups as far as I know.

to make the backup of stock rom recovery is needed to be modded for work on bml partition layout it should also be compatible with rfs partitions

Question about rooting and install custom rom.

Hello all!
I'm new on this forum. I have questions about Xperia X8. About 1 week i will buy xperia x8(with android 2.1). I want to root it. I have found tutorials on net but i don't really understand, am i going to unlock the bootloader if a root my phone and install custom rom(I'm thinking to install Froyobread)? I don't want to brick my phone so is it safe to root? Also if i have Custom Rom(Froyobread) can I use market to install free apps?
Thanks
P.S Sorry for my english

rooting is easy. just use superoneclick. bootloader unlock is more difficult and dangerous.
for froyobread you wont need a custom kernel. you can us gingerbread roms 2.3 to without flashing a kernel. i have locked bootloader too.

It's safe to root your X8, i recommend this program to do with: http://forum.xda-developers.com/showthread.php?t=803682
It's a very simple and great program. U just need to connect your phone with USB Debugging, and click on root. Thats all
If you want to change the stock kernel (most of roms can run with stock) u will need to download stuff, and make these steps. http://forum.xda-developers.com/showthread.php?t=1254225
Also, make sure, your phone is able to do these processes.
And If you have a costum rom, you can download free apps from market. It's very simple.
To install a costum rom, u need just to read a lot of about it.
Good luck!
If I helped, please click on the THANKS button
magyarlovag

So that means with rooting i won't brick-damage my phone(if a follow instructions carefully)? What 2.3 android Rom to choose for daily using?

Will froyobread run on stock kernel(will i need to unlock bootloader)? Also is there a tool so if a brick(damage) my phone to restore to old state(i have heard that Sony PC Companion is doing that)???
Sorry for stupid questions

Every rom have it's own advantage. I'm using now Alfsv8 kernel, with GDXv22.
It's a very good rom, for almost everything. But nAa's kernel and rom are very popular and great too.
Rooting is very simple with this program, you can't miss it
EDIT: Most of GingerBread roms require the latest nAa kernel, but I prefer Alfs As I mentioned, u must unlock your bootloader to flash a costum kernel.
And yes, you can restore your phone if u accidently brick ur phone. You can make the restore with PCC.

So if i want to install froyobread i will need to change kernel. Is kernel automaticly installing when i browse and choose to install custom rom in xRecovery 0.1. Or is there a special procedure for that?

No, it won't get installed with a rom automatically (it would be too simple )
http://forum.xda-developers.com/showthread.php?t=1254225
Read this thread carefully, and u will know how to do it.

Wait but luisniklas said that i wont need custom kernels for froyo. I also read tutorials for installing custom rom for froyo and i don't find anything for custom kernels. I don't really understand is there a difference between bootloader and custom kernels? If i need to change kernel, i'm not going to risk my phone at all.
Sorry I'm so boring but i really don't understand this things
Update: I found that Froyobread is going to work on stock kernel? Is that mean that i have to skip that hard procedure(changing kernel)?

Some rom will work on stock kernel. I dont know which ones, minicm, gingerdx and the other better roms need to change the kernel. If you don't want to change the kernel, u will need to test the roms by yourself. With stock kernel, maybe u will have wifi, notification bar, bluetooth, camera, fm radio and other bugs. The performance will also won't be fast.

Thanks for explaing that. Now if someone know answer me:
WILL FROYOBREAD WORK ON STOCK KERNEL?

Look.I'll make it as easy as I can get:
First,you root.It's simple, easy and safe. Search for instructions about SuperOneClick.
Then, you install xrecovery.This is necessary in order to install rom.
Then,you choose the rom you want to install.Every rom mentions if it runs on custom or stock kernel, or both.
I suggest since you are new, you should not try to unlock your bootloader yet, you don't want to end up hard bricking your phone.
Go to the rom you want to install, and see if it says stock or custom kernel.And then, you save it to your sd card, you go to xrecovery and install it.

I found this http://forum.xda-developers.com/showthread.php?t=1079463
There is nowhere said that this rom need stock or custom kernel. What will happen if this rom needs custom kernel and i have install on stock?

After you install it, your phone will be stuck in the Sony Ericsson logo. That's what happens.

This one will works on stock

I want to be safe, so I will make a backup of stock rom in case this custom rom not work. I'll make backup and then if get stuck on sony ericsson logo i wall restore to stock. Anyway thanks guys for explaing me, if I stuck on some steps i will ask you.
Edit: Last stupid question: So if this rom work on stock kernel i won't need to change kernel or unlock bootloader?

Yes, that's what it means.

No, you won't.
But after u learn things about the X8, u should change the kernel too.

install recovery after rooting. use the xrecovery installer. if you cant find it pm me and i will help you. in xrecovery you can backup your current rom with apps etc .
i use GingerXperia(with all xperia apps) V22 on stock kernel. its very nice.
i something gets wrong you mostly can restore your phone with sony ericsson update service.

Installing 2e recovery for SGS i9000

HII ALLL.....
I m a newbie here...
Recently I got an SGS i9000 from my cousin which runs on FROYO 2.2 . Its very outdated so I thought its time that I give my SGS an update. For this I rooted my phone and installed ROM manager so that I can flash clock work recovery in it. But even after flashing CWM successfully it boots in android recovery. Its only then I got to know that my phone rune '3e' recovery and I need '2e' recovery for this.
Since a few days I was browsing on how to revert 3e recovery of mine back to 2e recovery. I found a handful of information regarding the same. A video in Youtube suggesting that I can use ODIN and flash the kernel to speedmod-k12 or i can even download CF_ root_"Build no".tar from xda and flash my kernel to get 2e recovery. Also to take a nandroid backup i need 2e recovery as 3e doesnt show any option for this. Can you suggest me which is the safest and best possible method to do the recovery reverting.
Details of my phone:
Model No : SGS GT-i9000
Firmware : 2.2
Baseband version : I9000JXJPE
Kernel version : 2.6.32.9 [email protected] # 91
Build no : FROYO.JPJPG
Also suggest me, if I am going to flash using CF_ root method , I cant find the kernel related to my build number JPG. Can I use JPE instead of that.
Thank you in advance

i think you wanna flash some gingerbread or maybe ice cream sandwich or jelly bean rom!
but for a person how hanv´t flashed anithing bevor i would suggest you only to flash gingerbread. becouse this ist the last android version suportet by samsung und till now the only one which has a stable releas for custom roms like minu or cyanogenmod (http://www.cyanogenmod.com/devices/samsung-galaxy-s).
the first thing you have to know is i think, that there ar different bootloaders for gingerbread.
so you have to flash them first like discribed in this thread:
http://forum.xda-developers.com/showthread.php?t=1011701
if you have done this you are free to flash any gingerbread (or above) firmeware you want to.
here is a list of some stock firmewares: http://forum.xda-developers.com/showthread.php?t=948790&highlight=all+gingerbread+bootloaders
these are not the fastest rom´s but they are stable, becouse they are made by samsung and there is only root integratet.
about the efs folder discribed in this thread. the efs folder is the lokation of your IMEI. in some crazy situations, most times only in not heavy testet alpha releases of for exemple cyenogenmod, ur IMEI get erased and with the safed es folder you can backup it the easy way.
for me personaly the best rom´s ever made are based on cyanogenmod. so if you wanne test it here is an update guid how to get cyanogenmod 7 (based on gingerbread): http://wiki.cyanogenmod.com/wiki/Samsung_Galaxy_S:_Full_Update_Guide
i hope i may helped you a litle

Hey
For flashing ics or jb u need 2.3.6..so if kies still recognises ur phone..i say update it from there...
If it doesnt goto sammobile.com and signup and download the firmware u need and also the flashprograms,flashguides...
Its simply...

Thanks for your guidance.....
Sorry 4 being a noob...But let me ask u something...Isnt it betr 2 take a nandroid backup before i proceed with the installation of gingerbread..Incase if it gets bricked i can restore it back ....
Since my recovery is 3e there is no option of backup and recovery...I used a rom manager and flashed CWM ...but read somewhere that CWM works only wid 2e recovery ... So I just wanted to revert back my phone recovery to 2e...I saw in youtube a video showing that if i flash my kernel with speedmod-K12-500hz using odin, I get a speedmod kernel and CWM recovery....
I was not sure whether doing this would cause any probs to the device or is it ok to flash speedmod kernel..???
Thanx in advance

My internet connection is not tat gud ..so i wudnt prefer updating via kies.....
I downloaded XXJVU 2.3.6 from androidsoul.com... I m just a bit worried that I cant get a nandroid backup cos my recovery being 3e ....I have already flashed to CWM using Rom manager..but it wud work only on 2e recovery...
So wat i wanted 2 ask is can i flash my kernel to speedmod-K12 for CWM recovery.....or is there a betr suggestion frm ur side...??

speedmod kernal is a good choice! i did it that way i flashed the first time.
i don´t know the number of speedmod for froyo but i think you have posted the corect number of the kernel.
if you want to be 100% sure that you won´t lose your contakts you can use myphonexplorer to backup them to your computer bevor you flash spedmod

Thnx in advance...

Dial in your phone: *#1234#
Look at CSC, it should be like CSC: I9000123456, the last 6 digits/letters are the CSC string, the first 3 letters of are your CSC code (Example: XEU, ITV, XSA...etc.).
Go to : http://forum.xda-developers.com/showthread.php?t=1102881 and download the firmware for your region and extract by using 7zip.
Enter Download Mode on your device and flash the firmware using Odin.
Find a Kernel with a build in CWM, almost all developers Kernels has that, flash as PDA.
Now you are ready to flash any ROM you like using CWM.
Take your time and read to know what you need to do and how.
Best of luck
