Returning to the stock without flashing it? - Galaxy S III Q&A, Help & Troubleshooting

Hello. I am new to the world of rooting and flashing and one learn as things go. I own SGIII III I 9300. I rooted it, installed CWM, then flashed Archidroid v3.1.3, installed TWRP instead of CWM, upgraded Archidroid to 3.1.4 without creating a backup before root. It works nice and all but I would like to get my old stock ROM back with or without root, just as it comes from a factory. The thing is I cannot find an appropriate stock ROM (I am from Slovakia and my zone is I9300XXUGNA8 - there are stock ROMs with this zone but they are not intended for my country) and anyway, it would take like 9 hours to download it without buying a premium acc. Before flashing Archidroid I made a backup in CWM, it has got several files of which 2 are ISO.
My question is, if it is possible to somehow get to the clean stock ROM? I was thinking of returning to the backup I made in CWM, but I am not sure if the backup is compatible with TWRP. After restoring the backup I would just do a system wipe (including dalvik and cache). Would it work? Sorry if this has been answered somewhere but I haven't found anything.

[Q] How to get nandroid backup working on newer roms

Hi
I'm having issues with doing a nandroid backup and restore using current stock roms such as KI3.
I read the boot loader changed here compared to older roms, but I'm not sure that this alone is the issue.
What I did is install a frakenstein stock rom, meaning the whole rom was put together from seperate parts of different versions from http://forum.xda-developers.com/showthread.php?t=1075278:
This Frankenstein™ Non-Wipe package has: PDA: XXKI3| Modem/phone: XXKI3| CSC: XEUKD1
Download: http://www.multiupload.com/7JTWS2E37R
Over this I installed the rooted rom from http://forum.xda-developers.com/showthread.php?t=1103399: CF-Root-SGS2_XX_OXA_KI3-42-v4.2-CWM4.zip
Just from the rom side of view, so using the phone with it everything was fine.
However now I did a nandroid backup and later a restore since I wanted to try Cyanogen mod 7.1
The restore itself ran through without errors, however I found that almost all .apk files of /data/app were missing, even google apps like gmail and market.
I heared CWM did not go well with the new boot loader so I tried running the restore after applying an older rom (first just the old boot loader) but this did not help.
I then found that the backup itself did not contain the missing apk files, so the backup process itself was not done properly.
To get to a working state again I had to extract the apk files from an older backup and collect the apks that were still missing manually.
After restoring again and then copying the apks using adb push I had the system working again.
Anyway:
It seemes to me that i had the original boot loader applied when doing the nandroid backup, but that was apparently not enough to get it running properly.
Can anyone help in creating a properly working nandroid backup from one of the newer stock roms like KI3 and KI8?
Thanx!
Can anyone help in creating a properly working nandroid backup from one of the newer stock roms like KI3 and KI8?
Standard method works CWM restore+ backup . Should know i have done ten backups and restores on KI3 today no problem

You mean so you do not have to use odin to flash a such roms?
I think you can make those yourself. Just do a factory reset, clear all caches and then use odin to flash the rom, and then apply root and go into cwm to create a backup.
You could share that backup with others.
Ofcourase that would not be entirely stock anymore since root and CWM would be included there.

Interesting - so no problems at all with CWM backup and restore based on a KI3 at all? Including custom settings and own apps installed?
Which rom exactly did you flash and how did you apply CWM?

Standard CWM backup/restore works for me too.
I used the same KI3 Frankenstein firmware as you (OP) but KI3-v4.1 of cf-root.
Thanx.
I installed the 4.1 kernel and also to be sure the old boot loader and made a CWM backup the data.img is now 259mb instead of just 100mb so I think now its a proper backup.
Now I can go ahead and properly try out CM 7.1

Some very basic ROM questions. Could not find an answer for 24hrs of searching!

Hello everyone,
I'm just about to go out of my mind, haha. I've successfully rooted my phone and I am interested in installing a new, custom ROM. However, I want to be 100% sure that I am not leading myself into the path of bricking. I have a couple questions that I think are basic enough, but haven't found an answer to anywhere online.
1.) Do I need a specific kernel and/or firmware in order to install a custom ROM?
2.) These are my specs for my phone
Android 2.3.3
Baseband: I9100DXKI1
Kernel: I9100DXKI2
Looking at my specs, will I be able to install this rom: http://forum.xda-developers.com/showthread.php?t=1198334 ?
Will any other ROM work for my phone? Now that it is rooted, am I freely able to install any ROM using clockworkmod or odin without having to change the kernels?
I'm very new to this and I'm hoping somoone can help me out with this.
Thanks a ton in advance!
Just rooting is not enough to install custom rom. You need to install clockworkmod recovery either through rom manager or flash a custom kernel which has CWM.
You can flash any kernel compatible with your device (for example, you cannot flash I9100G kernel/firmware on I9100 model).
You can get a lot of information here at xda. All the developers here are very friendly and co-operative.
You're good to go. Backup apps and some data using Titanium backup and/or My Backup Pro or something like those. Then boot into recovery, make a nandroid backup (can be found in the recovery menu), and flash the rom of your choice. You can flash any rom you like, just don't forget to wipe! This is also an option in recovery, wipe data/factory reset. You can also wipe dalvik-cache (found under 'advanced'). Have fun flashing!
Thanks for filling me in guys. I do have CWM installed on the phone, so I'll back up and try to flash. We'll see if I don't brick the phone somehow, haha.

Well obviously you wont, all you can do with flashing a wrong rom is getting boot loop, you can always restore your previous rom via nandroid backup. Happy flashing

Stock recovery question

So I probably should of asked this before flashing but anyways, I flashed CWM to my tablet and I am about to flash aokp to it but I was wondering if I was going to go to back to complete stock again does it matter what stock 3.2 recovery I use to get official updates? I did make a nandroid backup so I am not to worried about getting a stock OS but its just the stock recovery that bothers me.
For the record I have a Canadian WIFI 16 gig tablet.
Official updates...? Odin is the only official update you need! :] Just so you know, you can't completely revert to stock unless it's for that specific firmware, only way to do that is by a clean flash to avoid all the un-necessary bricks and such.
Nandroid backup does not exist on stock and last I checked the recovery and CWM do the same job of "Applying update.zip" so it shouldn't matter, it's the firmware's regional value that matters, not the recovery.
So if I were to do a restore of my nandroid backup (from CWM) then that means that I would be able to get the notice that I would be able to update to the latest official firmware from Samsung no problem?
As long as you don't use Cus ROM's then yes.

[Q] Correct way to first time flash ROM... then return to originally running one?

Would the following work as a way to try out, for example Cyanogenmod 10. I am currently running a 4.1.2 install (pretty much stock just rooted/cwm via Philz as per the tutorial). I have a complete backup made via Philz recovery of this rom along with the kernel (which I believe is still stock from that) and efs.
1) Install a custom kernel (eg. dorimanx 9.x?) via the Philz recovery.
2) Install cm-10.2-20140102-NIGHTLY-i9100.zip.
3) To return to the original rom, reflash the original kernel (with whatever CWM is included in dorimanx) - then reflash the backed up rom via the same recovery?
I hope this is clear enough a question.
I believe you have to flash a stock rom through Odin, to return to complete stock. Just flashing a stock kernel isn't enough, and is surely not going to work (so don't do it).There are also tutorials how to remove the yellow triangle afterwards.
Please correct me if I'm wrong

This is the part I'm most unsure of. Ideally I'm trying to figure out the process that lets me go from CM10.2 (and whatever recovery) to the point I am running the backed up rom rooted with PhilZ-cwm6-XWLSW-XEU-5.06.1-signed.zip again. Very confused on how to do so.

Topher,
If you have rooted and cwm via philz, you already have a modified kernel installed. I believe the philz-cwm6 should be as close to stock kernel with the CWM incorporated. You don't need to add another kernel, because it will be replaced when you install the custom ROM. You should just be able to flash the cm10.2 via philz or via odin. You can then flash the dormanix kernel if you want - can't comment on that kernel - or if it has cwm included.
I would also suggest that you consider backing up you /efs folder (one with you imei information etc) prior to flashing any custom roms. People have been using hcKtool to do the backups and also an actual copy as well.
Depending on the custom rom, you may have connection problems with your network. So you may want to consider keeping a copy of your modem.bin file from your stock rom handy in case you need to flash onto the custom rom.
If you want to go back to stock, then you just need to flash the stock rom - you can check sammobile website for your stock rom or use the backup that you made.
I should point out that I have yet to do any of the above - I gathered this from reading the forums. Some more experienced forum users can add corrections. I rooted my phone a couple of months ago and now considering installing custom rom in the next couple of months.
Thanks.
if u flash a custom rom (cm10.2 for example), it already included kernel as well. so if u want to try out other custom kernel, i can flash it after you are done flashing a custom rom but make sure it is compatible with your android version. (u cant use custom kernel that not support android 4.3 with a custom rom running android 4.3)

Newbie to flashing, rooting, etc - several basic questions

Hello,
So lately I've been have some troubles with my phone and I decided to try and flash with a new ROM and see if that helps.
I've been reading on the forums some of the guides, FAQ, and read about some ROMs but I'm still a bit unsure of the entire process.
Currently using GT-I9300, 4.1.2 OS, stock.
Backup:
1. Do I need to flash a custom recovery tool (CWM/TWRG) to create an image backup? Should I just root with Odin and then use Titanium?
2. Do these backup my EFS partition or should I back that up separately?
3. Do I need to root my phone with Odin to be able to flash custom recovery tool/backup my EFS?
ROM/Kernel flashing:
1. Since I'm a newbie to this and there seems to be a ton of ROM options, could you recommend on a stable CM based 4.3 ROM I could use?
2. I haven't seen a stock 4.4.4 for GT-I9300, is it stable to use?
I'm sorry If I've asked something thousands have asked before, I couldn't find a clear answer in a decent amount of time.
Thanks for the help!

Backup
(1) Titanium only backs up apps and data it does not do a full (Nandroid backup Google it) Root with cf autoroot http://forum.xda-developers.com/showthread.php?t=1980683 and then flash a custom recovery (choice is yours cwm,Twrp,PhilZ flash with Odin)
(2) Yes some custom recoveries back up efs PhilZ does I think twrp does not sure about cwm ( I don't think it does maybe wrong on that) nandroid backups don't backup your efs do this separately
(3) Technically you don't need root to flash a recovery but if you want to backup anything in recovery then you need to root.You will only need to root your phone once if you are intending to flash custom roms (so that you can backup) because root is included in custom roms.
IMPORTANT! You must backup your efs once you have flashed a custom recovery especially coming from 4.1.2. and keep multiple copies on phone and pc!
Rom/Kernel flashing
(1) We cannot recommend roms it is against XDA rules
(2) Their is no stock 4.4.4 roms last release was 4.3 anything else is a custom/port of 4.4
Thanks for your help, that cleared up a few things.
I ended up using samsung galaxy S3 toolkit (which is amazing btw) to root & load insecure boot image, flash custom recovery img and backup everything on my phone.
I'm now ready to flash my first custom ROM
Again, thanks a bunch
