[Q] Restore problem using CWM recovery

Hi guys can some one please help me..
I bought my Galaxy ace last week with gingerbread 2.3.4 (India) in it. i had taken backup using CWM 4. then i updated to CWM5 and installed " CyanogenMod 7.1-cooper-KANG-RC1 Android 2.3.7 (upd: 12.10.2011)" on my phone. i almost liked this ROm but this ROm eats up my battery very fast.. so i decided to roll back to my official ROM which i had backed up. but when i restore the phone it gets stuck in Galaxy ace screen.
Please help me .. how do i restore my backup.
there were no errors during the backup nor during the restore..
Please help..!!

in cwm do a full wipe and then try to restore backup --> never tried this but somewhere read it works...
if this doesn't work then flash ddkq6 firmware from sammobile.com with odin.. install cwn and rollback backup
try the first one ... second one surely will do it

it has been asked many times ...search forum ..... it is not restoring because cm 7 uses ext format..and stock uses .rfs.... so u have to convert .ext to .rfs before restoring ... this can be done with ext manager ...( comes with cf-root)
Press thanks if i helped.

Wait. Whatever you do, Making a nandroid backup of your stock rom won't work, it tends to create a md5 file mismatch, a few times, and don't ask me how.
Well, I hate to break it to you, but, just use ODIN all over again,load a stock rom, and things should be as light as rain. But then again, you'd revert to that crappy standard recovery, so flash that with cwm, once you're done ^_^
Ooh, and if I helped, click that shiny 'thanks' button, then.

well i don't think ext4 manager will work on cm roms even if they are running ketut's kernel as ext4manager checks the kernel you are using..... never tried it ..ketut might have made it to work on it but no one is gonna change fs to rfs on that kernel

hey i know the last option is to flash thru odin .. but is there any other way to restore it thru CWM.. please let me know..
and ya one more thing i m following this thread to falsh thru odin " http://forum.xda-developers.com/showthread.php?t=1242925 " Please tell me whether is it correct and safe..

Hi @amitkhetan69...
Sorry to break it to you this way but you are not getting back to stock from custom rom without a full Odin re-flash of stock rom...
Have you tried @Jusada's IceCream Sunday2 (Extreme speed) rom...? Use this rom with a good script that has the ability to manage system resources (check my sig for scripts (V8.5 etc.)). These scripts give excellent battery managment along with many other top drawer tweaks...
There really is no need for you to go through the headache of returning to stock (unless your returning the phone for whatever reason).
FYI : You will need CWM5 to flash any CM7.2 rom... CWM4 will brick ya phone flashing 7.2 rom... "DONT DO IT" CWM5 only for 7.2 roms... I see that you have CWM5 but this could be just incidental to your situation hence my warning (in case you did'nt actually know)...
Stay Breezy n Be Lucky...

Bro, this is because CM7.2 RC1 that you are using is having an ex4 filesystem where stock roms have rfs filesystem. In order to resove this problem, ive made a guide: http://forum.xda-developers.com/showthread.php?t=1606336
Only go uptill STEP 3, if you wish to retain your custom recovery and root.

[Q] Question about Flashing ICS

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!

Now when I flash this bootloader you listed, will Froyo still boot or will I have to flash my ROM afterwards?

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

Hi all.
as i can't post yet in a thread mentioned by mrnapolean1 (http://forum.xda-developers.com/showthread.php?t=1362092) I'll try to ask my question here, as it related to a question asked by this thread starter
so i have gingerbread 2.3.5, installed CornKernel_UCKK4_v603 and custom rom SimplyStock KK4 V1.0 , so if i wanted to switch Team ICSSGS [Android 4.0.3] should i do following?
1. wipe data /factory reset
2.wipe system
3.flash from recovery mode Android 4.0.3 zip?
I already have a backup made with Efs Pro as a tar file
anything else i need to do?
thank you so much in advance

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

thank you !
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.

ok, in the end managed to boot the phone with working wifi but still would like to know how to flash back to SimplyStock KK4 V1.0, just in case ;-) if that won't be problem for you. thank you !!!

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

Tab p1000 boots to android recovery after aokp fail??

hi all
well after flashing my p1000m(bell canada) numerous time,i got adventurous and tried to flash ics .
AOKP SGT7 BUILD 40
updated to stock bell gingerbread,rooted.
used odin to install overcome kernal 4.0
installed build 40 thru cwm,everything seemed to go fine.
went into bootloop with aokp screen and some audio message.
tried to flash back to original bell gingerbread with pit file and repartition checked,all seemed to go well but now boots to android recovery.
i think the partitions are screwed up.
i have original bell gingerbread with pit.
unit charges,goes into recover and download mode so seems softbrick.
odin detects and always finishes with no errors.
tried all the usual un brick tricks but not working.
any help appreciated

Stock via Odin:
Which "stock" gingerbread rom did you use in Odin? Are you using Overcome's gb_stock_safe .tar?
Bootloops:
After first flashing AOKP #40, it should bootloop since it first needs to update the recovery version as well as convert to mtd. Did you then go back into recovery and flash AOKP #40 a 2nd time? The 2nd flash installs the rom.
Btw, is your p1000 gsm or cdma?

hi
got it solved by the overcome restock rom.
but i only flashed once.
now running aokp build 40 ,most apps fc,i will reflash and see if that helps.
thanks

You need to wipe before flashing AOKP (or even after flashing, no harm)
And never restore system apps from gb to pics, or across any dissimilar rooms.

phone won't boot after flashing cm10 and going back to stock via nandroid

Hi guys,
I just need some short advise:
My dad flashed CM10 nightly a few days ago.
Before that he had a stock froyo rom (i don't know which version exactly) but with root and CWM.
Flashing CM10 worked but he had same bugs (baseband deleted, reboots every 10 minutes), so he flashed CM9 stable hopeing to get these things right. but it didn't, baseband was still gone. So he decided to restore his nandroid backup and go back to his froyo stock.
but that ended in a total disaster and the phone won't boot anymore. it is stuck at the white "Galaxy S" screen (before boot animation).
My dad said, that he tried to restore his backup a 2nd time. but he got many errors including "unknown volume for path /data"
He is a little bit frightened that he could brick his phone completely so he asked me for help.
Well, I don't know what to do besides flashing a stock gingerbread rom + kernel +baseband/modem with Odin.
Am I right with this? Or do you guys got some other advise for me.
thanks for help

try factory reset must done after restore

are you sure?
shouldn'd this be done before restore?
by doing a wipe, I would need to do 2 restors in order to keep my apps..

As the partition layout of CyanogenMod and stock are different, and thus stock partition layout is needed, you have to flash stock using Odin with pit512 and partition enabled. After that restore should work as well.
Besides: If baseband is missing in CM, try to flash a CM modem.

Galaxy S i9000 update

Hi all,
I'm still using my Galaxy S on Froyo and don't feel I need to upgrade to a new handset yet but I would like some advice on rooting and getting my phone updated to the latest and greatest F/W (Custom or standard) so that I can get the best out of my phone and give it a new lease of life. Can anyone point me in the right direction? I've already used Odin a while ago to update from Eclair to Froyo so I've had a bit of experience with this apart from rooting and loading custom ROM's Any help or advice would be much appreciated.

Thanks for that. What is CM9? Will I need to root first?

I've just attempted rooting. Does this result from Odin look normal?

Hey, Tox. Thanks for the advice. Why CM9? There are later versions, is CM9 the most stable? I'd like to try Slim Bean. Do I need to install that CM9 before I attempt to put Slim Bean on? Also, will I need any other files/apps? I've checked that my i9000 is rooted ok by doing an su in a terminal emulator.

Could anybody point me to a straight forward tutorial which could help me from where I'm currently at?

I've now installed clockworkmod recovery and created a backup to the SD card in recovery mode. I'm guessing the next steps should be pretty straight forward. I just need to know which files I have to download. What's the best Slim Bean for me to try and what other apps should I install with it?

Ok, I've screwed up. I installed clockworkmod recovery and created a backup. I tried flashing the latest Slim Bean ROM and addon pak but my phone wouldn't connect to the cell network. I attempted to recover from the backup using CWM but my phone is now stuck in a bootloop with the Samsung splash screen. Can anybody help me please?

you lost your IMEI , that's why i told you to flash CM9 first , to avoid loosing IMEI ,
reflash 2.3.6 firmware via odin , root it , flash CM9 , then flash slim bean rom

Thanks. I've just flashed 2.3.6 again and then applied CWM recovery but it still boot loops. Do you know why I couldn't just restore from the backup I'd created?

How can I flash the CM9 pack with Odin? It's a ZIP folder and wont recognise it. Please help.

Is there any other way around this? I've just installed SB again with the addon pack just so that I could get the CM9 onto my SD card. What's the best way to sort this out and get my IMEI number sorted?

Can anyone help me at all?? I have the IMEI number in the back of the phone if that's any use?

this how to install cm 9
Put it ( zip file ) to your phone's internal sd-card
Reboot to recovery (vol up + home + power)
Wipe data/factory reset
Wipe cache
Advanced > wipe dalvik cache
Install zip from sd-card
Choose zip from sd-card
Select cm-9.0.0-galaxysmtd.zip
Confirm
Wait
Go back
Reboot
the same you way you do with a JB rom
and please push thanks button ,

Thanks for the reply T. So should I do a full wipe (Wipe data/factory reset Wipe cache Advanced > wipe dalvik cache) before installing 2.3.6, then apply the CWM update followed by your instructions above? Will that recover my IMEI because, as you said, it's definitely no longer there.

I've just wiped everything and installed GB 2.3.6 and got the following messages. Does this look ok? Also, after I'd done that, I rooted it with CWM then tried installing the latest stable CM10 but now when I reboot, it shows the CM/Samsung screen as if it was booting then it just goes back to the CWM recovery What do I do now??

Success!
I've just powered up my phone again and suddenly the Cyanogen startup screen appeared! I powered down and put the SIM back in from my backup phone and I'm back on the phone network. I was reading up on lots of other complicated ways of recovering the IMEI and this has been really straight forward. I'm liking the Cyanogen 10.1.2 so far so might stick with that. Thanks so much for your help TT!

So to answer a few of your questions, I know I'm late to the party but for future reference
-The reason why Tox recommended flashing CM9 first is because problems can occur going straight from 2.3.6 to Jelly Bean in terms of your IMEI- your device's "identification". If you lose the IMEI, you lose the ability to connect to your network provider. Flashing CM9 and letting it boot as an intermediate step prevents this from happening. Once you've booted CM9 when you flash and you have reception, you're all goods to flash any JB rom from there.
-Your bootloop from recovering the backup that you made from Slim- I'm guessing it was a backup from 2.3.6- has nothing to do with the IMEI. Phones can boot without the IMEI. Its because the data partitions in 2.3.6 are different to those in Jelly Bean. Hence they're incompatible with each other- you tried to restore a different data partition that what was available on Slim Bean (because it was Jelly Bean).
-Flashing any 2.3.6 rom will restore your IMEI. However regarding the photo you took with the red error messages...
-That's because of the reason I mentioned above, with the data partitions. Because they're different, the phone can't recognise them and so can't boot, hence resulting in a bootloop. Easy way to fix this- there's a file called dbsdata.rfs.tar (its somewhere in these forums, right now I can't find a link). If you get that situation again, just pul the battery and reinsert it, go back into download mode, put dbsdata.rfs.tar in PDA, let it flash. That should put the right data partition on the phone.
Hope that these clarified some of your questions!

Now I've learned a little more, I can have a play around with different ROMS with a bit of confidence. :good: Any suggestions on good things to try out? I think I still need to apply some add-on's for this CM10.1.2 build as I don't have market place, google, FB etc.

Click to expand...
Click to collapse
Don't forget your Gapps ;3 (most roms need them to be flashed seperately)
Good things to try out as in?
