Help Needed - Downgrade from Marshmallow to Lollipop

Hey Guys,

I upgraded on last Friday and really cursing myself now. The marshmallow update has screwed my phone, buggy, unstable.

How can I now downgrade to official stock android lollipop ?

Any help would be great.

Thanks

how to downgrade the lg transpyre to kitkat?

Hi guys, I am a newbie to smartphones in general and seem to have myself stuck in a loop. I have a lg transpyre that I was trying hard not to upgrade to lollipop because it would unroot it (I got it rooted before as kitkat). I guess at some points in time I forgot to uncheck the auto installing checkbox so now I have lollipop :crying:.

I have another identical transpyre that still runs rooted kitkat. I am researching on maybe somehow copying the operating system from this phone to the lollipop phone (I guess it calls flash?). So far it seems to me that such attempt would require both phones to be rooted.

Can anyone guides me to the right direction? I really appreciate any help I can receive!

I545VRUGOF1 need help with root or downgrade to COF1

Flashed GOF1 by mistake from sammmobile using Odin. Now can't find a root method that works. Tried to flash COF1 using Odin but get fail message. Anyone have any suggestions? I'm really just needing root to get backups restored from TiBu. Much appreciated if anyone has suggestions.

Desperate to Downgrade to Gingerbread

Moderators - my apologies if I have posted this in the wrong area and please relocate it.

if anyone knows a safe and proven way to downgrade my Samsung Galaxy Ace 2 GT i1860 to Gingerbread I would be eternally grateful.
there is a lot of info below, but I find it is of no use asking for help without explaining what and where I have been up to so far, so please bear with me.

after suffering some woes and a near bricking it currently has Jellybean 4.1.2 Baseband 18160XXNA1- Kernel 3.0.31-1106830 se infra@SEP-64#2 SMP PREEMP on it,
plus it is rooted with a temporary CWM on the sdcard.

I need the downgrade to be able to run Copilot Live 8 or 9 - ver 8 worked fine on GB, but not on JB whereas ver 9 on JB is useless.
see this link: https://forum.copilotlive.com/copilo...ent=topic_link

some googling suggested downgrade was possible and I tried these 2 links:
1. http://www.droidviews.com/how-to-dow...android-4-1-2/
sadly Yandex would not give up the file.

2. http://www.ibtimes.co.uk/galaxy-ace2...erbread-455579
this link is what caused my near bricking and days of anguish.

the downloaded 18160XXLK6.rar file did not extract the 3 files named in the tutorial:
CODE_GT-I8160XXLK6_CL1211243_REV00_SEC_KEY_LK6-4G.tar.md5 -CSC_GT-I8160-MULTI-CSC-0XELF1_SEC_KEY_4G.tar.md5 and GT-I8160_EUR_XX_4G.pit
but it just contained I8160XXLK6_I8160OXXLK1_HOME.tar.md5 and SS_DL.dll and when I looked into the rar file itself it had some image files.

nonetheless I followed the instructions, but just put the one md5 file into Odin -more than likely that is where I went wrong because the phone ended up nearly bricked and had a Data partition that could not be mounted nor formatted, so I could not restore any CWM backups. after days of downloads I did get it back up and running.
I think it was HOME_I8160XXNA1_I8160BTUNA1_I8160XXNA1_1106830_REV 00_user_low_ship.tar.md5 that got it sorted enough for me to restore a backup.

no doubt I have been a right prat - I obviously know just enough to be dangerous, but please be kind to a 70 year old plonker
