[Q]Reset Factory Default Firmware

Hi there.. recently i've updated my firmware to v10e.. When i tried a new kernel, it got bootloop and had to divert to latest cwm backup..
Then i realised, the backup cwm is v10d version. When i tried update through LG Updater, the software detects that currently im up-to-date.
So, is there any way to reset the factory default firmware so that i can update? :-?
Current settings:-
- NeoBlaze 120811
- Stock v10d, rooted

I have a similar question...I think.
I want to revert my phone to the original LG rom, I am on FIDO in Canada...
I looked at this thread:
http://forum.xda-developers.com/showthread.php?t=1035041
But wasn't sure which one to pick...
so my question is:
how can I revert my phone to the original state that it came in when I got it from Fido?

I've tried using NVFlash.. but still the "factory default firmware" is the latest.. hurmm..

I think you will have to smartflash an older baseband (pre0725) , then you can use the lg updater.

I also think thats the solution.
By restoring your backup, you mixed two ROM versions. Now you currently use 10d + the baseband from 10e (since CWM backup/restore cant handle basebands) - that's why LG updater doesn't work.
Flash the corresponding BB for 10d, if that doesn't work then returning to 10a and updating from there on might work. (Caution: BB flashing wipes your device, do a nandroid backup before!)

Lost IMEI after flashing

Hi everyone,
Recently my phone loses IMEI after flashing any ROM, even after flashing kernel only (Semaphore 3.0.0 on CM10.1.3, for example). I have flashed the phone many of times before with different ROMs, kernels, sounds, fonts, animations, etc., but never had this issue before. Something has changed and I don't know what it is. It's getting annoying I just did a full cycle by the book: Format int/ext storage -> One-click stock ROM -> One-click Corn kernel -> Cyanogen 10.1.3 Stable (flash to repartition, flash the again). The phone works perfectly. Flashed another JB ROM to test, the same one I have flashed many times before with no issues (HellyBean 4.2.2, CM-based), and bam - lost IMEI again!
I have no problem restoring IMEI. The question is why the phone loses IMEI now after ROM change but never before?

What you describe suggests something has changed in the install scripts on either the CM or Helly roms.
It seems like flashing 10.1.2. instead of .3 would test CM as cause.
sent from one of my two SGH-I897 Captivates

I was thinking about this, it started somewhere around CM 10.1.2. But if the cause is changes in CM installation, then am I the only one experiencing this issue? I don't see many comments about lost IMEI on 4.2.2 ROMs. Yes, I know it happens, but not on every flash. I tried flashing Xylon 2.3.3 ROM, the one I flashed at least 3 times before with no issues, and same thing - lost IMEI. Seems like EFS is now in a place that gets wiped every time I flash something.

I tried installing cyanmod 4.2.2 and lost my imei. So I flashed back to 2.3.5 I think ill leave it where its at

Try again. Android 4.2.2 is much better than stock 2.3.x.

The phone will stay unlocked. Just try again and you"ll be fine. Use latest CM10.1.3 Stable release.

Is it a one click Odin file. I have the one for 2.3.5

Micromod...Do we need to have DD'ed the 12b aboot from JC's post? Or will any old loki'd aboot work as long as we flash XDABebb's stock kernel with this ROM? I take it we need to also flash the KK baseband. Should we flash the baseband first or make sure it boots. I know we will have to flash the 12b baseband to restore our old 12B rom such as Malladus 1.2.9.
Thanks to you and everyone else who havn't seen this allowing me to download @ 3MB p/sec

Thank you for this. I will download and test. Can't wait for your debloated version.

You need to have done everything needed to get on 24a plus everything needed to get the recovery on 24a. Older roms or backups will not work with 24a recoveries without old basebands.

I don't think this makes a whole lot of sense... If I currently have TWRP 2.7 and an old aboot. All thats required for this to flash is BB, ROM, and patched Kernel. Do we need to apply the recovery img from JC's thread or is the TWRP 2.7 we already have gonna work?

He states you need a 24a custom recovery. You could try just getting the 24a recovery.

I do not think it will work without getting to stock rooted 24a first. You can try it but I would not do it. I am on stock rooted 24a with the 24a version of TWRP. It is not terribly difficult to do.

I agree with this. In order to avoid confusion and a million requests/doesn't work replies can MicroMod provide a guide to flashing this in the OP. Even if it is copied bits from JC and XDABebb's guide I think it will help quell the issues. Most people's eyes probably will light up thinking this is something most can flash in the current state to avoid the commands some feel are dangerous. I know quite quickly in the ATT and TMobile threads there was flashable content entitled KK the easy way which seemed much more straight forward than this does. To clarify I am not complaining I just wanted to get the real skinny and help others understand if this is not a KK the easy way type zip. :angel:

There is no 24a custom recovery, per se. I believe what he means is that you'll need a custom recovery so that you have the ability to flash this. In order to do so, your aboot/bootloader will need to be 12b as that is the last loki-exploitable version...which is therefore the only way you can have any custom recovery at this point.
I think it's an excellent idea for someone to make a flashable zip for those that just want to update in that way, but please keep in mind that there are a number of other partitions involved beyond system, boot, aboot, and modem that should also be updated properly. Improperly mixing/matching/flashing them can cause problems. I don't want to scare anyone off of doing this...just make them aware.

I posted this so we can find a working kernel.

You just quoted that you only read half of what he said. 24a OR KitKat kernal patched to work on 12b. The same way people are installing cloudypro 2. There are two possible ways for us to get a 4.4 stock ROM.

Is this because my aboot is most likley still 10b from ancient times long forgotten. I have never OTA'd only flashed custom JB roms of AOSP and Stock currently Malladus 1.2.9 which is 12b?
Thanks to everyone so far and appreciate direction.
Edit: Scary restore...my restore backup window was empty...I played around with TWRP 2.7.0.0 after I flashed the 12b radio back. Had to wipe everything but internal again, Go into advanced...Unmount all parts...remount all partitions. Use file manager to search the backup directory to make TWRP self aware and then I could restore.
Restoring now to Malladus 1.2.9 (12b)
Edit 2: Restore completed...re-flashed 12b Radio and Furnace 1.7.1 kernel for good measure. Wiped cache and dalvik once more cause Ill wipe till I'm bloody successfully rebooted.
What we all learned: Restoring is not a big deal but I don't know what would happen if you flushed TWRP out of RAM by accidentally rebooting after any failure. I am assuming power+down vol would be fine but please don't make an ass-umer out of me

Correct. There's a check in the script that verifies you have a 12b aboot. It's just for safety, so if you feel brazen you can change the "vs98012b" to "vs980" in the loki.sh script.

XDABebb before I go all Rambo has anyone tried any KK related installs with 10b/11a? I do not really think there is much of a diff and I would have thought that with all the weird security issues with 12b when it came out devs would just have tried the older less quirky aboots to begin with. But I can't make that call I am just a Lemming on these forums
Looking at it from the opposite perspective I have been using 12b JB kernels with whatever aboot I currently have for the last few months with 0 issues so in theory...who's up next LAWL

From what I have gathered the only important step is to DD the 12b aboot to your device and then everything should come easily once we have a solid kernel....I attempted it earlier and the kernel check failed because my aboot is 10a since I have never restored a tot/kdz or took an OTA. I haven't gotten a response back if we can DD the 12b safely while on a JB ROM in the interim so we have a backup that will work while we are testing kernels.
To answer your question though we need a new Kernel that works with KK 24a and has been patched to work with the 12b aboot and boot image.. We don't necessarily have to worry about hte boot image because that is included in the flashable ROM its just the specific aboot that is killing most of us. I also asked if it could be written to work with 10a and 11a aboots as well so it wouldn't matter since they are really the same except the revision number. I also haven't heard back on that subject either.

Hi
If you've done a nandroid backup, flash it.
If no backup, you can safely flash with odin a 4.2 ROM from sammobile.
Done the both because of some problems with kitkat and worked fine even if I'm on kitkat now with everything working fine.

I was wondering the same thing myself cause i tried several times with different Stock ROM's without any success??
When you are trid to flash it comes up with some kind off authenication error (The only ROM i able to flash is the 4.4.)
And i am not even able to Root without getting stuck during boot. Tried several senarios.
CF-Root causes boot lock
T
ried Also : recovery_6.0.4.7.tar.md5
Then i get this Warning: kernel is not seandroid enforcing
Status for SE for Android:
Enforcing + type details
Build no:
KOT49H.I9295XXUCNE4
I read somewhere that a Stock ROM with modified files could do the trick:
http://forum.xda-developers.com/showthread.php?t=2715435
Maybe such a ROM would do the trick? Maybe someone else has done this work already.
i hope so - cause It kinda sucks running a Stock ROM

revert to 4.2.2
hello,
i have a GT-I9295
i have updated from 4.2.2 to 4.4.2 PDA: I9295XXUCNH2 released 7 aug. via odin 3.09
had to do a factory reset to get wifi working, etc..
i then wanted to revert back to 4.2, but i couldn't, and still can't... i did the following:
- flash with odin the 4.2 from sammobile: error: NAND Write Start!!.....<ID:0/004> Complete(Write) operation failed. soft brik, Firmware upgrade encountered an issue. Please select recovery mode in Kies and try again.
- tried to reflash the 4.4 firmware i already had with odin...same error.
- couldnt boot the phone again untill i flashed cwm 6.0.5.0
- installed carbon rom from cwm no problem. did reset, wipe cahe, format system, etc. i now have the not seandroid enforcing message when booting and entering recovery, but everything works.
- tried to flash again with odin the 4.2 official, still no luck. same error right after nand write.
i remember downgrading from 4.4 PDA: I9295XXUCNE4 to 4.2 PDA: I9295XXUBML3 with no problems a while back on my other i9295 via odin.
is the bootloader different in this version of 4.4 i flashed than the one i flashed a while back?
the weird thing is that i get the same write failure with reflashing 4.4 with odin.
any thoughts?
thank you

Small update. You will not be able to downgrade from next after ne5 versions of KitKat.
