[Q] Downgrade Ace 2 GT-I8160L to GB from JB

Hi, Last week I upgraded my Ace 2 GT-I8160L to official JB in hope of improved performance,speed and stability but what I got was random hiccups, freezes and reboots. RAM was increased to 624MB though, is there any way to downgrade it to GB just like GT-I8160 ? I can't find odin files for PIT & CSC of GB firmware for GT-I8160L

You can't go back to GB. But try installing kyrillos v8. It's insanely fast I heard. Follow the link on my signature

But you can, sure only tested on i8160P but i am pretty sure it applies for non p and l versions. Just need to have proper dump and backup of cspsa, efs and modem fs partitions.

edit the updater-script in the V8 rom to allow install on the "L" otherwise you'll get an assert fail error.
assert(getprop("ro.product.device") == "GT-I8160L" && getprop("ro.build.id") == "JZO54K")

Best ROM is CM 10.1. It is fast and stable, it has only a few bugs.

[Q] Any other solution other than reverting back to 4.1.2 for lag issue ?

I am fed up with the lag issue in this GRAND duos. tried all these methods
(1) reverting back to amf7
(2) flashing bna4
(3) flashing ubmk3
(4) disbaled stock gallery app
(5) disabled as many as possible official apps....
All the solutions proved to be just temporary. After 24 hours to 4 days it starts lagging again. Now I am sick of flashing firmwares.
My phone is under warranty up to 19 April. If I go to service center and ask for replacement of motherboard/phone, will they replace just on the complain "my this phone hangs a lot. I have googled and found that many users have flashed other firmwares yet phones lag. These users say that this problem has no solution but replacement of motherboard?" (I cannot tell them that I have flashed other firmwares myself).
If any user with same problem has flashed custom ROM, please share your experience.

Bro, though I've never flashed a custom rom on my grand , but my Grand is rooted and I've flashed a lot of mods on it , but my Grand never lags . It is very fast and buttery smooth . I want to ask you that wether you directly started flashing custom roms on your galaxy grand or in the beginning you just rooted and flashed some mods like me ?

@MohdGhufran
From what date is your last stock ROM?
I'm having the same problem. But I've used the CM11 on another occasion and did not face any problem. Then I went back to Stock and updated the same last week.
The phone was very bad (lag). So I returned to the CM11, but the lag continues.
I'll try an earlier stock and after the CM11.
I'll post the result here.
(Sorry for my English by Google)

@Mohdgufran - I agree... I m running umbmk1 ... after 3 to 4 days with out restart the phone starts to lag...
The only solution temporarily is to clear the ram in task manager...
Stay wid 4.2.2 and use a ram cleaner (it sucks a bit battery but its the only possible non technical solution)

Have you tried a factory reset, followed by clean flashing a smooth ROM?? In my experience, THAT always solves any problem...

Its the stock rom that is cursed..:/

I think u need a reverse gear.. First back to 4.1 version then flash with 4.2 November month version then use cm 11 custom rom.. Its fast.. Gud battery back up.. No lag.. And all with dual sim.. I hope this will work for u..

Try greenify and the cleaner both are small apps (around 1 mb) and it will speed up your phone .....
Hit thanks if you find this usefull

Didn't root.

I have not flashed any custom ROM on this phone. Neither have I rooted it. This lag issue started since my bro got an OTA update. So, as per solutions/guidance available on xda, I just flashed official firmwares (which proved to be just temporary solutions)

it is not like that stock ROMs are not good. It is just a problem with Galaxy Grand Duos. I had rooted my Galaxy R and Galaxy S Advance and had flashed Custom ROMs. All the custom ROMs had some limitations / missing features (like USB PC connection, wifi tethering, USB tethering, etc). This is why I do not want to flash any custom ROM on Galaxy Grand.

Yes I had tried this. Went back to 4.1 and the upgraded to 4.2. This too proved to be a temporary solution.
I don't want to flash custom ROM but now it seems like I will have to flash the same.

I solved my problem by not installing facebook and twitter as well as also installed battery saver pro which kills apps running in background for every five minutes..

Radio issue is common in all custom roms and to use dual sim functionality you can use cosmic cm v3 for good performance (if camera crashes while video recording you can use google camera instead of stock one)

Hello,

Unknown issues are common like only one sim support, etc.
Through, this ROM doesn't have any unknown issues I suppose.

yeah it is a good rom ( Gennext custom rom is not updated since november last year ) but it based on 4.2.2 JB which means it only supports JB functions . if you really want to use JB rom for good performance you can check PyramiD V2 and *TouchWiz Revolution* V2[Stock 4.2.2]....

[Q] Safe Procedure to Downgrade from 4.4.2 to 4.1.2

Hello all XDA members especially in our beloved Note 2 community :good:
I've owned my Note 2 since it's first launch.. I'm satisfied and proud to have one of the best phone ever made from Samsung. :good:
I have questions related to downgrading process, just want to confirm the process coz I don't want to brick my Note 2.
My mighty Note 2 is on Omega V.28, 4.4.2 Android Version with MJ5 bootloader and latest TWRP. I want to downgrade to 4.1.2 as I missed the 4.1.2 balance among performance and battery life.
My question are :
1. Can I just flash Omega V.18 (4.1.2) or the others 4.1.2 custom rom (not interested in stock rom ) directly from TWRP ?
2. Won't that procedure brick my phone ?
3. Will I lost my imei and signal ?
4. Can I flash existing modem to fix lost imei (XXUENA) ? Will it compatible with 4.1.2 (Omega V.18) ?
Thanks all for the answer an comments.. :good:
Cheers for Note 2

As long as you are on MJ5 bootloader you can flash 4.1.2 custom ROM via custom recovery.If you lose signal flash any of the modems either from hurricane modem changer or your current one if you have a flashable zip file for that.

HELP!! How to restore original NOTE2 7100 ROM ???

Hello all,
I need help,
I flashed my origianl rom without backup using TWRP ...... i tried a 4.4.4 modified rom, cm11 and another lollipop modified rom
They are all giving problems, slower and overall worse than the original rom
could you please direct me to a tutorial to install the latest original note 2 rom please ?
I didnt change the kernel, it should be the old original one
phone is currently rooted (i used auto root)
And the bootloader/recovery is TWRP from TEAM WIN.
How do i go back to the latest original note 2 rom pelase ??? thank you very much in advance! :fingers-crossed::good:
edit:
going a bit off topic here but if anyone would know any of this 2 you d make me happy
1. what are the fastet lollipop custom ROMs? i like the interface but it tends to be slow ...
2. I miss the s Pen visual feedback dot on screen when i moved the pen nearby the screen in the original rom, do you know how to get that feature back please?

Didn't you do systembackup either with twrp? maybe you can get stockrom back that way.
maybe you can try cm12.1 it works ok for me (about 30% for me now)
