[Q] Downgrading - LG Optimus G Pro

ATT forced my E980 to update to 4.4.2 while i was sleeping. re-rooted the phone (even easier the 2nd time).
Really, the only issue i have is firefox will not play videos. i hear its because of flash with kitkat.
So, can i downgrade to jellybean 4.2? (what the phone came with).
i have searched until my eyes went cross-eyed. the "instructions" were not easy to follow and it seemed that it was some sort of full flash that would erase the phone. i have spent may too much time getting the phone set up how i like to change it all again.
So, is it possible to either flash without erasing or backup everything and reload it easily?

Nope.. u can't flash without losing data unless u hv the cwm backup.. check the about how to flash tot on E980.
Hit thanks if I helped you!

Or use dolphin with working flash for 4.4

[Q] upgrade without losing root

Good day! My wife has her phone rooted with the stock 4.54 ROM that was in her phone when I rooted it. Has anyone come up with a way to update her phone to the current 4.67 version without losing root?
I know that I can just get a rooted, stock 4.67 ROM and flash it, but that is going to freak her out...starting over, so to speak. I guess like a few others I'm waiting for a rooted 4.67 update for a 4.54 ROM. If anyone knows of anything that can help, it would be great. If I could just let her upgrade and then re-root it using revolutionary, I certainly would.
Thank you for your time.
Only option is to back everything up in titanium backup, mybackup root, ultimate backup pro or something similar flash a stock rooted rom and restore all the apps and data for contacts just sync to Google and SMS use SMS backup/restore from market

You could just do a nandroid, then wipe just cache & dalvik cache (I'd probably wipe boot and system too), then flash one of the stock rooted ROMs. That would preserve all the data, though it might cause some instability. But if it doesn't, you're golden. I might play around with actually putting together a rooted OTA zip, though I personally don't see a need for it. But that's a project for tomorrow.....
Thanks for the input, folks. I guess I'm going to go with the full backup of everything and flash the rooted stock. She'll just have to deal with it.
Have a great day!
Get Titanium or My Backup. She will lose call log and SMS. If this is an issue the get SMS backup. I flash a different ROM atleast twice per week and it is simple with Titanium. It usually puts every app back before I even open titanium. If something is missing you just go in and click restore.

So, per my post above, I was able to put together a rooted version of the OTA, but there are some restrictions on its use, unfortunately. It'll only work if you are currently rooted, and haven't removed any system apps. The OTA looks for each file that needs to be patched and if one is missing, it'll error out.
If you want to try it, let me know. All you have to do is flash it in recovery, actually. It's just like any other zip.

[Q] T889 Bricked, TWRP works, Wiped Everything, Have Android Toolkit, Now What?

Made big mistake. Downloaded Android Toolbox (PRO). Rooted 4.3 successfully. Trying to go to 4.1.2 from 4.3. Did Titanium backup. Downloaded Mr Robinson root66 ROM. Using TWRP (latest), made mistake of wiring everything (not extsdcard). Now stuck at the first Galaxy Note screen when the phone is turned on or I can get to TWRP. Feel dumb as a stump, but can't seem to move from here. Help!
All I really want to do is get back to an operating phone, be it with 4.3 or 4.1.2.

Sorry for the long-winded whiny first post. I'm just stumped how to flash a ROM back on the phone. Can I use TWRP to flash a new ROM? I usually have been able to muddle through but I'm really confused at this point. Anyone have an idea?
Thanks

If you can get into recovery you should be able to flash a custom rom, If not you will have to use Odin and flash a t889 rom to your phone preferably mk7.
Does your phone go in to download mode ? If yes, does it recognized by ODIN ?
If TWRP is working then you should not have any problems flashing any 4.3 rom via TWRP.
Thank you for the hint. I finally woke up after these replies and made the phone into a non-brick again. XDA continues to be my source for all things related to my toys.

[Q] Downgrade from Custom 4.4.2 to stock 4.3 possible?

Hi everyone I hope this is not a repetition of some old thread (I tried but couldn't find though).
I was using my note 2 (T889) on stock 4.3 which i previously flashed via odine. A couple of days ago i came by this good looking kitkat based rom ( eZKAT v2.0 ) and went on to try it. the rom flashed flawlessly and after flashing my modem i got the signals as well but the wifi was not working. tried using dr. ketans wifi patch but didnt get the wifi to working. Anyhow, I decided to go back to 4.3 via odine. The odine flashing completed successfully but i got stuck on T-mobiles boot screen for hours.
Is there anything called "you cant go back to 4.3 from 4.4.2"? If yes, then whats the way around? I really need to go back to the stock.
Thanks.

I had this problem on my Note also. Downgrading versions of Android requires a data wipe. You will need to reflash your 4.4 ROM then backup your data if you want. Save your backup to your computer then install the 4.3 image.

I already tried that but still the booting stuck on the t-mobile logo. I read somewhere that locked bootloader don't let you downgrade to previous version. Is this true?
In that case. Try finding a 4.3 rom that's close to stock.
Sent from my Nexus 7
The locked bootloader is always in stock firmwares i.e 4.3 for the Note 2 but not in custom roms meaning u can even install Lollipop custom on it & downgrade smoothly, i have done that many times. The problem is 4.3 stock firmware has locked bootloader hence downgrading still keeps u in 4.3 bootloader even if u remove all the KNOX files.
Stuck trying to downgrade from custom 5.1.1 to stock 4.3
Hi, i have a problem like this, upgrade to a custom 5.1.1 and then sell the phone, the new owner wants to have it stock, i try to downgrade to 4.3 but i cant, in odin i set the phone to flash it but seems like it doesn`t recognize the phone and i dont know why, so, i decided to try in recovery mode installing from the sd card but the sistem abort, so, i don`t know what to do, i`ll appreciates any help, sorry for my english, i do my best. (i have root access before upgrated to 5.1.1).

flashing lollipop update

i need help here. here's my scenario. im using lg g3 d855 with kitkat 4.4.2. i got an OTA notification update to lollipop (v20b SEA), since im rooted i tried to flash this using the lg flash tool with the correct kdz file. i was able to update it to lollipop and everything seems fine; however since i find it pretty big(for dpi) and also not rootable yet, i tried to downgrade again to kitkat (v10k) and it went fine. i was able to root it using purpledrake l, then install twrp to revert back to my nandroid backup. so overall, everything went back to normal.
after 3 days, i decided to go thru to lollipop again
so i did the flashing of the update, but after all of this and during the initial setup, i noticed that mobile network isnt working. i tried to ignore this and just continue to finish the setup. after all is done, and im on the homescreen. i noticed that i dont have the navigation button. also when i tried to switch on the mobile network, it was grayed out. i tried all the possible method of reflashing back this lollipop updte(even redownloading a fresh copy of the kdz file), but to no avail.
question is how to flash back this lollipop update with all functions working?
any help will be much appreciated. sorry for the long story!

thanks a lot! looks like it worked for me. i flashed the KK modem, then flashed chupachups ROM... now im in lollipop again with my root retained!

i need help updating from 4.1.1

ok ppl.. I really need some help.. ill try my best to describe whats going on.. I bought my phone a couple years ago.. rooted it, install custom recovery straight out the box and never looked back... I have never updated bootloader or modem... and am currently using dlk3 as both... I wanted to clean my phone, and finally update bootloader, modem, and everything.. so I odin back to my origal stock.. android version 4.1.1 thinking I can just manually do the ota update.. but when I update it says um currently all up to date using 4.1.1 I tried using kies, but that also says im up to date....
so now im lost... I know you should do them in increments but I don't know wich order.. and I know when you get to a certain point theres no going back.. kinda why I never updated... I really want to get everything updated to the lattest version of stock.. latest bootloader and everything...
I thought the last update was 4.3.. so where did the NE4, NJ1, NJ2 come from?? wich just confused me even more?
oh, theres a 4.3ota thread.. basically said odin 4..1.1 wich I have.. then install 4.1.2, then 4.3 from a sdcard.. but my phone always had problems with sdcards.. and nowdays wont read any sdcards.. so that's not an option for me..
any information is appreciated
Is the system completely stock? Did you do a factory wipe using stock recovery after flashing 4.1.1? Did you try removing your sim card and moving the date ahead by a couple of days?
Yes.. everything is completly stock again.. including stock rocovery.. yes I did a factory reset with stock recovery after flashing 4.1.1.. yes I tried removing the sim.. and yes I did move the date ahead a few times searching for update
If you just looking to update the bootloaders and modem without going through the OTA, this may be a place to start: http://forum.xda-developers.com/showthread.php?t=2387423
Thank yoh audit13.. thats the thread I was yalking about in my OP.. that requires the use of an SDcard..
I shoukd have RMA this phone when I had a chance.. within the first year, it corrupted corrupted 3 sdcards in the forst year.. so I just stop using them.. they still read nust fine in my pc.. but now my phone wont even read them.. so im really at a loss
Sorry, I didn't notice the part about the external sd card in the thread I linked. I don't have the i747, I have the i747m and the stock 4.4.2 ROM is available for mine.
I think Kies has been replaced by smart switch.
Not sure what else to suggest other than copying the files to the internal memory and trying to flash the update that way.
i did see something about smart switch, but didn't update thinking it wasn't needed.. maybe that's my next step..
I don't see flash from internal with stock recovery.. just ADB, cache.. wich I don't know what they are.. or external.. those are my 3 options
could this be my problem? befoer odin back to stock.. I used triangle away.. used it before with success.. but I notice when im in download, flash counter says 1 and everything else says official.. I also notice when my recovery, my android guy is laying down with a red triangle..
any information is appreciated
The android laying down is fine.
With the external ad cards, are you using the phone to format the cards?
but what about the flash counter reading 1? I would still think it d/l but not install.. that I could fix if I could get that far.. lol
I use to format the sdcards in my phone.. but after a few months they become corrupt.. cards read just fine in my pc, but phone refuses to see them.. I been trying to get them to work formatted as EXfat.. NTFS is my second option
The best format I found is using a computer to format them as fat32.
The download counter is not an issue. As long as as you don't see the word "custom" in download mode, you should be fine.
You may just have to just wait and try the Ota update every few hours.
forgot about FAT32.. I do remember reading that was best...
and im running out of options, so I think your correct on the OTA
I been running TWRP and liquidsmooth 4.4.4 for ever.. and it was great.. but I wanted to run there lollipop.. but it wont boot on my phone.. I was told its because my bootloader is so old.. I also remember readin awhile back that updating bootloader can solve SDcard isuues.. but I have no clue about that..
thx for the suggestions audit.. ill make sure to thank you
Let me know how fat32 works. I am curious myself.
The latest custom Roms definitely need a kk bootloader and modem, preferably the latest nj2.

not meaning to butt-in. audit13 knows his stuff. :thumbup:
"all i can really do , is stay out of my own way and let the will of heaven be done"
no.. fat32 no go..
and im on jellybean..
couldn't I just odin 4.1.2, then 4.3.. but im having problems finding none rooted versions.. that I would trust.. I was hoping for OTA.. all that odin makes me nervous.. to many opportunities for things to go wrong
Just to confirm, the phone is running 4.1.1? There is no Odin i747 flash for 4.1.2 as far as I know.
In order of preference, I like OTA, Odin, and then flashable zips because OTA upgrades are the safest in my opinion as long as the phone is running stock.
ATT never released a full firmware for the i747 beyond 4.1.1 which explains why it is not available on sammobile.com.
yes, I am positive everything!!! is stock 4.1.1.. it was what was on my phone when I got it.. always made sure to have a stock image on hand.. and I never messed with bootloader or modem.. and i have verified there ucdlk3
I agree on OTA being safer.. but would you suggest I do now?? I really want to get this updated... 4.1 blows coming from 4.4.. lol I could always just set it the way I had with an easy root.. but I really wanted to try lolipop
All I can suggest is flashing the bootloader and modem in tandem since you can't seem to get OTA updates.
Check out the general thread. There is one for mjb, ne4, nj1, and nj2.
Do you have to flash them incrementally? I don't know as I don't have the i747.
