[Q] Reset Back from Cyanogenmod to Galaxy

Hello, I post my problem here, because i'm new in this forum, and i can't post y Galaxy Ace forum.
Yesterday I installed Cyanogenmod in my Samsung Galaxy Ace, searching video in Youtube and reading the forum. Really, don't like the Cyanogenmod, it have some much details and options that I really don't use it. My cuestion is, how can I go back to my Gingerbread 2.3.x in my phone?
I'm from Chile and some words that u use i really don't understand. I someone can help me I'll be very grateful, maybe an the most basic explanation possible.
Cheers.

http://forum.xda-developers.com/showthread.php?t=1449320

Well I got the same question too but my question is; is it posible to just full reset the phone erase the cache partition and flash it back with the gingerbread ROMs found here?
http://forum.xda-developers.com/showthread.php?t=1300843
I just got hold of the ICS ROM for a day but I am thinking of going back to gingerbread since it drains my battery faster than before and the functions are a little bit confusing and I am looking for familiar things that I like before on gingerbread but can't find 'em like the task killer, my files option and the sim card option. also it is very slow on booting up like the kernel glitch will show for a minute then the android icon for another minute.

Welcome to xda y'all
Yes u can
Follow these instructions
- download a gingerbread rom for ur galaxy ace
- restart ur phone with power + volume down + menu button pressed
- you'll see a screen with small text. This is called recovery

-press home button
- wait
-press back button, then select reboot phone

[Q] Updating my flashed Galaxy Nexus

Hello!
Well, I own a Samsung Galaxy Nexus which originally were a yakjuxw but I "converted" it into an yakju. And now when Android Jelly Bean is reaching the surface I would like to know how to update because in the guide i read they said that I may have to update by flashing again.
I've also read this guide: http://forum.xda-developers.com/showpost.php?p=20843237&postcount=1 But I don't understand anything.
I don't know what "Stock recovery", "CWM recovery" or "ADB" is and I'm having a hard time with this so I would really appreciate if someone would want to help me with a detailed guide or explanation of the words.
Pretty much anything would help, thank you!
I have installed CWM on my phone since I now know what that is and I I have also unlocked the bootloader. Thought that may help!

wat you got to do is find the stock firmware file for your phone and carrier (probably on sammobile.com). Then download odin 1.85 and put your phone into download mode. Then oin odin make sure the "re-partition" box is NOT checked and and click PDA and look for the file you have just downloaded. Then plug your phone into the pc and wait for odin to recognixe then press start.
Now you will be back to normal. Just update as you normally would now
To cack up your apps download Titanium Backup and open it then go into batch mode and backup all your apps but not your data. Then save all tbhuis on your pc and redownload it when youve updated to jellybean and put it back in the Titanium Backup folder and restore all the apps.
You should also do a NAND backup from clockwork mod which wou would have to download and put on your phone the same way mentioned in the first paragraph.
This all assuming you are rooted.
Hit thanks please

Well I haven't rooted my phone and I don't think I will in a while so that won't work. But thanks anyways!

You don't need Odin. You do need to be rooted. If you can wait 2 weeks you will get the official update.

help find and install i9305 ODIN and root tools

Hello all android experts superior to me. I am just a simpleton right now but I am hoping I can learn how to feed myself over time and actually contribute something back to this developer community. Your patience is greatly appreciated.
*Yes I have already read every single thread for my device and not been able to find a clear solution without risking bricking my phone.
*The video asked to be brief but clear. I was not brief, but clear.
*
I am a noob and I am very interested in learning how to mod my Android Samsung Galaxy 3 i9305 (details).
Samsung Galaxy S3 LTE Hong Kong Version
Model number:GT-19305
Android version: 4.1 .1
Baseband version: 19305ZHALl1
Kernel version
3.0.31-177985
**
I have spent about 20 hours of research and got conflicting results.
I am looking to do the following things (in order) and I would deeply appreciate any specific instructions (with specific device only and complete software file names and versions please) any of you might help.
1) Root the phone
2) Install the ODIN application on a PC (Win 7 Ultimate 64 bit) so I can actually back up my device to an external PC. I am amenable to using the mobile ODIN program offered but I need to know what specific ODIN application will work for the device. *Note yes my KIES drivers installed for USB to PC connection working fine and will turn off KIES when using ODIN
3) Install CWM or something similar so that I can copy my own device ROM and save it for back ups in case I lose my phone or wifey smashes it.
4) Use CWM or SU program of some sort so I can flash my own backup ROM for backups AND try out other people’s custom ROM’s.
5) Find or build a custom ROM that is devoid of bloatware and google extras.
*
Only component I need to retain is to be able to use the Samsung Chinese IME supplied keyboard since I need to read and type Chinese characters in pinyin.
*
Thanks for listening and sorry for being such a dullard, didn’t know how else to start out learning this. I am very interested in learning more and would appreciate any reading suggestions you might offer.
:cyclops:

Nice work, Some people flash there phones before reading everything properly and brick there devices, But you did a very good move by doing NOTHING untill 100% sure. Because of this thread and my instructions bellow I decided create a thread (What to do after you buy the 4G S3) Either go there or just keep reading on here.......
So before you flash anything, or start playing with your gem, follow these important steps below to get all the important parts backed up and safe, so that you will not have to return your device back to samsung broken. Believe me I have seen it happen PLENTY of times in this forum, so read carefully
Make sure you have a Good USB cable and a stable PC and that don't get any power outages or surges, you dont want to be half way through something and you loosing power or bad connection.
1st: Install Samsung Kies on your PC this will then Install the Samsung USB drivers you will need to connect your device to your PC OR you can get the samsung drivers on there own from the Link in 2nd step, but I recommend you install kies as it may be useful to you in the future.
2nd: Now as your IMEI number is like the heart of your device lets back it up right now: Follow only part of these steps in this link, you will finish the rest of the backups at the end when your rooted. I have copied and bolded the parts you will need to do right now, once finished this section of the backup you should be left with a *.qcn file which is roughly around 250kb of size.
http://forum.xda-developers.com/showpost.php?p=33048706&postcount=1
*Setting up QPST with your PC:*
*Backing Up IMEI / NV Data:*
*Restore USB Settings after Backup / Restore:*
Now keep that page open because you will return here in step 6 once you are rooted to complete the backup process.
3rd: Now Install Odin V3.04 - You can get the link for odin in the 4th step link, So you may aswell just continue on to 4th step as the instructions inside that link advice you to install Odin aswell.
4th: Now you must Root your device and install CWM recovery , Follow these steps carefully > http://forum.xda-developers.com/showpost.php?p=32235061&postcount=1
5th: Once you have root I recommend you instantly make a full backup of your device also known as a Nandroid backup. You must go into recovery mode to do this with the CWM recovery you have just installed in 4th step above.
6th Now lets finish the backup process since we are now rooted, I am going to say this again, this is VERY important incase something goes wrong and you loose your Imei and Data, you need to back it all up. By doing this it will save you returning your device back to samsung like many have done previously because they have not done this, Remember where you left off in 2nd step above? Well now you can go back and complete the partition backup of the efs folders. You should be left with 4 backup files for this final section of the backup process >>> http://forum.xda-developers.com/showpost.php?p=33048706&postcount=1
--------====FINISHED====--------
Congratulations you now have your Imei/Nv data backed up , You are rooted and Nandroided. Now you can play around but off-course DO NOT be reckless make sure you know what you are playing with
Peace
PS: Only trust what you see in this I9305 XDA forum, as i have been following the device from day one and I can only recommend the information you see here.

I appreciate your altitude of ask before risking.
Well, I'd give you process & advices for your question.

You inverted step 1 and 2.
1st: Either -
a) Install Samsung Kies from the enclosed disc / Samsung's site
OR
b) Install the SAMSUNG Android USB Composite Device Driver (Google it Yourself)
2nd: Download Odin (from CF-Auto-Root thread)
3rd: Root by
a) Install CWM -> Root
e.g. ClockworkMod 6.0.1.5 and SuperSU zip package;
b) Root -> Install CWM
Install pre-rooted Firmware / CF-Auto-Root then install CWM from above
4th: Better backup your ROM and /efs (IMEI data and etc.)

In fact, you just RESTORE backup not flash one. They work differently.
You can flash ROM zips in CWM or Mobile Odin by ChainFire and Odin tars in Odin or Mobile Odin

Well, there isn't any AOSP ROMs (Android Open Source Project, which developers build directly from source code) yet, but only modified stock ROMs.

You could try some other replacements like Go Keyboard.
If you still get questions fell free to ask me even in Chinese (not in thread but PM me)

Seems like someone did not read the thread before postin instructi0ns again, lol . But. Anyways i gues it does not hurt having more instructions, well my instructions is exactly the way i did my phone. It was done in those steps and i am sure its clear for you. Pick and just follow 1 set of instructions d0 not confuse yourself by lo0king at 2 sets of instructions as it is a different way shown in the last post.

Nice guide however I would recommend step 5 to be the first thing to do after installing the drivers as EFS area is very important.

I've done back up you detail but can't do the other until rooted? Is this correct

Thanks Liyriquid. I thought you needed root to do the QCN as i did when i was rooted but since you dont have to that is the best idea. To the OP >>>>>>>>>>>>> I HAVE NOW EDITED MY INSTRUCTION POST.
Please Note that you will ONLY be able to dp the QPST Tool QCN backup before you are rooted but to complete he partition backup you will need to be rooted. So just follow my steps i have broke up the steps for you easily to figure out
Edit: My guide should be the first thing people look at after buying this phone and start playing with it, as it links you to the most important guides and steps you need to take to keep it backed up and safe

A big thanks to btemtd for putting this easy to read guide together.
Also thanks go out to lyriquidperfection for the initial guide on backing up the EFS.
I have only had my S3 for a few days now and am keen to try a few different ROMs out on it. I also have an original Galaxy S that I have been trying out many different roms on for the last two years I have had it. Had a lot of fun doing so, and look forward to the same now with the S3. Can't wait to get Odin fired up and CWM installed. Let the fun begin !

I am thinking it may be a good idea for that instruction to have a thread on its own,

Is there any chance of it bricking my device when installing Cwm and leaving on me unable to get my imei details stored?
Also is a nandroid backup a complete backup image of my firmware as I'm not quite sure what this is a and why I need it.
Thanks

Hi guys. I'm considering the 9305 but I have a question.
Can you install any 9300-ROM on the 9305? Kernel and baseband aside, of course.
Or do all (great) ROMs need to be recompiled for the 9305? It the same Exynos 4412 in the bottom, should work to flash most 9300-ROMs?
Thanks.

Yes it should not be too hard to port over, You just need to abit of fiddling around, A noob wont be able to do it, but someone who knows what they are doing should be able to do it easily You just need to change the updater script as the partition location has changed so you just have to tell the rom installer where you want it to install. which is what the updater script.
Kernel + and base firmware need to be changed. I just dont understand why more expereinced people have not done this yet, i guess they dont really care about roms

I really cant see how you can brick your device if you follow those steps VERY carefully as this is what i have done and most of us on here, and make sure you have Good usb cable and stable PC and don't get any power outages or surges

I don't think it will brick your device. Recovery partition is a relatively safe one compare to /boot, however it may happen.
It won't break your /efs except you flashed CWM over efs partition and overwrite your IMEI.
Nandroid is a complete backup of your phone. It's useful because you can recover your Android if you did made something wrong.
You may better think Nandroid is a kind of 'snapshot' of you phone.

Soon I will show you all how to make your own pre-rooted Odin packages!

[Q] Reflashing I9003

First Thanks to all of you for supporting I9003, and for helping us noobs
I have th GT-i9003 from like a year, great phone. it came with the LUBKPE stock firmware from entel in chile, and i updated it to XXKPQ following the tutorials here in XDA, also updated the kernel to [email protected] #15, i've got root cwm and a tweaks icon.
The problem is that like 2 weeks ago i installed a program called prey anti theft, after that when i try to enter CWM it just stays in a black screen same for tweaks icon, no problem with root.
So i decided to reflash my phone to get everything working fine. After a lot of reading decided to install the stock DDFL2 thats claimed to be the most stable stock rom for this phone.
1.-My first question is, i have read that i could screw up my emei doing this becouse a band incompatibility with this stock firmware (indian) and the bands used in my country (chile) is this true?? dont know if a got it wrong but thats what i understand of it.
2.-Also i read about making a backup of folders of the phone so in case of something like that happens i could recover it. So how i do this and what i need to backup??
3.- Third i read about bam kernel being better for stock firmwares, and [email protected] for customs is this true?
4.- when reflashing in the steps i read "flash KPE+pit twice", but in another forum i read of flashing KPE+pit and after that just flashing KPE (without pit) which one is the way to do it??
5.- and last, the wipe cache, clear cache and dalvik cache is done after the first boot, before i adjust my phone parameters?,or after that?, or before it first boot?? the first time id never did this but is said to be useful.
Thanks for taking the time to read my post and for ur replys.
PD: and for rooting ddfl2 is best bagaria? ddfl2-cfroot? cfroot.apk? superoneclick? Thanks!

1)As far as I know ddlf2 is universal stock rom.. it wont screw up ur imei.. Bt S.. It has been designed for indian phns.. U might lost local language supprt/app etc on ur fone.. if u face any prblms, u can easily revert back to original rom using nandroid backup..
2)Jst root ur phone with cfroot(which installs cwm as well) using odin.. Then go to recovery mode >backup & restore>nandroid backup
3)I don no vch kernel is better.. Its purely depends upon ur usage/preference.. So try every kernel on ur phone atleat one week then compare the petformance.
4) I suggest flashing kpe with 4 files twice.. it will clean off ur phone..
5) can do it whenever u wnt..

The i9003L and i9003 are the same phone, the "L" means it has a diferent modem, but the specs are the same and their roms are also the same. Also The L or Latona is for "Latin America"/Latinoamérica. So thanks again and sorry for my bad english!

Since you are from Chile, you need the modem for your country.

Thanks for ur replyes they really helped me out.
That means that after i flash the DDFL2 rom i have to flash the Modem.tar.md5 file of the xxKPE, and with this i activate the bands of my country?
And also i have read that people with the SCL version of the phone dont need to do this, but the ones with the L version do. Thats real and how i know wich version i have? i have read of a guy that claims that his L version phone transformed into SCL... dont really know what this means.
Thanks.

Yes, you would need to download a software called Odin. You also need to download a compatible firmware. You stated you have a N-7100. Your firmware should be available here. Simply search for N7100. If you do not see yours listed, please let me know.
If you do find it, put your phone into download mode (hold Vol Down + Home + Power), open up Odin on your computer, then plug your phone to your computer, in Odin, select the "PDA/AP" tab, a window will popup, select the file you downloaded (it will be in a .tar format, if it is in .zip, simply extract it and you will find the .tar file), wait a few seconds while it checks the file. Once it is ready, select start. It will take several minutes to finish and you will be back to 100% stock. You will be able to update your phone without receiving that error. Hope that helps.
EDIT: Here is a video I found that may be useful. It is step by step.

unrooting N7100
You don't provide enough information (stock /custom rom, reasons for unroooting,...) for an easy answer imho.
Don't deem me rude ... but to my reckognition it's the best way to start with learning 'how do I make good use of web & forum search mechanisms' - before trying to mess with some complex devices' firmware.
