OTA Update turned Galaxy Pocket Boot Loop

Help Please?
I had my Galaxy Pocket rooted and got the Jellyblast v3 rom, it was doin fine until I checked on the app OTA and check for update, a new update appeared which is the Nemesis 2.5 Hybrid-Holo Editon. It asked me to download it and so I did. When it was done, it asked me if I wanted to install it and so I did, and rebooted. Later I noticed that it was already boot looping. I tried pulling the battery off and to clockwork mode, with the proper procedure..the holds and presses, but still it just kept boot looping. Tried to connect it to the PC using the USB chord and yet it just shows the charging icon and sooner it turns to white. I tried Kies but still it turned white screen all over again; no device found.
Can someone PLEASE help me with this one? PLEASE, PLEASE guys? I know you guys are knowledgable on these kind of issues. :crying:

I also received the same message and downloaded the update file. when ask to Reboot & Install i selected install the device booted in CWM and i selected update from .zip and selected the downloaded file in OTA Download Folder.
The update was successful, yet the ROM looks in BETA version.
Following are the issues i am currently facing in the updated ROM
1. Gallery ICS was Force Closed, later it was solved via uninstalling update.
2. Quick Panel, Nemesis Hub, Nemesis Owner Info & Nemesis Sound Boosters are giving FC messages.
3. OTA is giving INVALID ROM Message while updating.
I´m having the same issues.
After downloading and installing the OTA update, my device is keep stucking in the boot loop.
When I do to the recovery, I always get automatic update with the update.zip, which means I can't get into the full recovery to select another functional image.
Well I hope it's not bricked. Is there a sollution?
Thanks

For all the SGY Users who are facing issues after updating Jellyblast 3.5 to Nemesis (I faced it too) here is the guide to recover your phone:-
First to repair your phone you have to flash stock rom via odin .
Here's the guide for Flashing Stock Rom via Odin
Requirement: 1. A Samsung Galaxy y phone model gt-s5360.
2. A computer running on windows xp, vista, win7 or win8 with proper USB driver installed to connect your phone to computer {If you have not installed USB Driver for Samsung Galaxy Y then to Install USB Driver}
3. Stock Rom file : you can download stock rom according to your choice and region from the xda thread http://forum.xda-developers.com/showthread.php?t=1465800e
4. download ODIN: 1 .85.(google it as i cannot post outside links)
Installation Instruction : [ Charge your phone battery min 80%]
1. Download the required file Odin AND Stock Rom. zip and place in a folder on your desktop .
2. Now extract both with any file extractor.-- Odin v1 .85 .zip and the stock rom zip( file which contains the stock rom i. e 2 .3 .6 )
After that extract Stock Rom file after unzipping you will get three files :
PDA _S5360 _DDLK2.tar,
MODEM_ S5360 _DDLK2.tar &
CSC_S 5360 _DDLK2 .tar
3. Now turn off your Galaxy Y {Remove the battery for 5 -10 seconds and insert it back }
4. Go to Download Mode by Pressing Volume down + Home + Power for 5- 10 sec to boot in Download Mode
5. Now you entered in Download mode select continue by pressing Volume up button .
6. Now attach/ connect your phone to computer via USB cable .
7. Now on your computer open Odin v 1 .85. exe
8.Now make sure you are getting yellow box in ID:COM ( this means that your device is now connected and detected by odin )
9.Now Select those 3 files u download before
PIT - "totoro_0623.pit"
BOOTLOADER - "BOOT" file.
PDA - "PDA" file.
PHONE - "MODEM" file.
CSC - "GT-s5360- MULTI-CSC" file.
10.Now clik on start .
And let be ODIN do its work and wait till you see PASS in green colour it mean the flashing process is complete successfully . Samsung
11.Remove your phone from pc 12.Galaxy Y will auto reboot .
Now if you want to install nemesis Rom, you have to install the nemesis Rom 2.0 (Nemesis Titanium) first and than you should update the Rom by downloading the update file via OTA and flashing the zip file through CWM.
I hope my suggestion will solve your problem.
Did you wipe data and wipe catch before installing ROM??
Did you try flashing original ROM with Odin or others??

hey mate. Use chairfire autoroot to root your s3.
I used it too to root my phone. It is best way.
Just goto chaifire website (google it) -> download the autoroot for your variant -> download Odin (I think it come inside autoroot zip) -> extract the zip -> you will find a .tar file -> put your phone in download mode by pressing vol down + home button + power and press volume up key -> connect your phone in your computer and let it install necessary driver. if the drivers were installed properly you will see COM id in odin. Only proceed if you see COM id. -> click on PDA and select the .tar that we extracted before -> just don't touch anything inside odin and click on start. Wait until odin say finished but dont disconnect the phone.
after the odin process there will be some process done in your phone so wait until your phone completely reboots and you see the SU app in your app drawer.
Now disconnect your phone.
Your phone will be rooted mate.
If you wanna experience s5 in your s3 then download the S5 sensation custom rom from the very great dev @sunajkram23. He has developed s5 rom with all its features and funtion for s3.
Before you flash any custom rom, you have a flash a custom recovery. I am using latest touch CWM recovery ( google it ) and download .tar file and then flash through odin ( same procedure to flash as I stated above ).

Sorry you're having trouble. I've never came across someone with a loop at optimization before. Maybe you can try to re download the file and repeat the process again. You might have a corrupt download.

Tutorial for downgrading to 4.3 jellybean

FLASHING STOCK JELLYBEAN​Hey guys, i have seen that a lot of people want to downgrade to jellybean 4.3 and facing a "fail" in Odin. so i'm creating this thread to overcome that problem.
Most importantly, clear the data of your phone before you flash the stock JellyBean. Otherwise you will face a bootloop.
Step-1: Download the following required files.
(All links are from my AndroidFileHost account so you dont have to login for any kind of websites)
Samsung USB drivers(for G7102 only): https://www.androidfilehost.com/?fid=24459283995316252
Odin: https://www.androidfilehost.com/?fid=24459283995316253
JellyBean firmware: https://www.androidfilehost.com/?fid=24459283995316591
Step-2: The actual flashing.
>Extract SAMSUNG_USB_DRIVERS_FOR_MOBILE_PHONES.ZIP AND INSTALL THE DRIVERS.
>Extract the Firmware file.
>Extract Odin ZIP file.
>Open Odin v3.10.7 folder and run Odin3 v3.10.7.exe.
>Reboot Phone in Download Mode by pressing and hold Home + Power + Volume Down buttons.
>Connect phone and wait until you get a blue sign in Odin.
Note: If you didnt get the blue sign, you did not install samsung drivers properly.
>Add the firmware file to AP / PDA.
>Make sure re-partition is NOT ticked.
>Go to options tab and select nand erase all (this is very important).
>Click the start button, sit back and wait few minutes.
Voila. You successfully flashed stock JellyBean on your samsung galaxy grand 2 (SM-G7102)
This worked on my device. and my friend's devices. i have tried in 2-3 devices. If u still fail to flash and brick your device im not responsible.
Firmware link updated.. if any1 tries, do respond here...
downgrading stable http://4pda.ru/forum/index.php?s=&showtopic=595850&view=findpost&p=35653052
i heard this method from someone...but the difference was that he told me to check the 'bootloader update' option also..is it ok?

Should there be the need to flash the
phone?
If yes where can i find the firmware for
the above mentioned model.
Kindly advice.
Greetings, @su2674raj
The answer is simple!
"Flash stock ROM"
There is a way to flash the firmware again. First unlock your bootloader
Requirements: A PC of course, A working USB cable, your A10, unlocked bootloader, Odin 3 or Higher, and a mind, some patience.
I am not responsible for bricking your device.
This is how to unlock bootloader. I just chooses a random YouTube video I don't own any content I WILL SEND.
Galaxy A series bootloader unlock:
Downloading "Samsung Odin"
Then download "Samsung Odin" to your PC. I prefer latest version.
Odin download link: https://odindownload.com/
Galaxy A10 firmware
Then download the Samsung Galaxy A10
firmware.
Galaxy A10 firmware: https://samfrew.com/fr/download/Galaxy__A10__/f4ji/PAK/A105FDDU3BTF1/A105FOJM3BTF1/
You can back if this isn't your A10 version and choose another one from the site bellow.
Now shut your A10 down. (To shut it down just hold volume down and power for more than 10 seconds. Now hold both volume keys while device is off... Then connect USB cable. Allow the download mode thing. And when it say "downloading" you will see a yellow thing appears in "Odin" tool.
Now... Unzip the firmware and open Odin.
The files inside the zip will start with something like this
A file will start with "BL" at the beggining so obviously load it in the "BL" section in odin
The one starts with "AP" will be putten in the AP section. Etc.
Warning!
The "AP" might take some time to load. It might say it's not responding but just wait for it. You are loading 2GB firmware.
After loading all the files simply click start. That's all! Wait for it and it will reboot . I hope this be helpful for you.
TROUBLESHOOTING SOME ISSUES!!!
If you connected your phone in download mode to PC but you didn't see yellow colour that means you have to install "Samsung galaxy USB drivers" from online.
After flashing... (Clicking start) if it finished and the ROM said Invaild... You have to get another firmware from another site (use a YouTube video I
recommend)
if the Odin stuck on "setup connection" for more than one minute that means you have to click "reset" then close Odin and restart your mobile to download mode again and start everything again.
TIPS!!
In "Odin" if you filled all the required files in thier right section there might be a section without a file in it. Just skip it
Consider installing twrp recovery for easier ROM flashing (without a PC!)
Android 11 ARM64 LINEAGE OS 18.1 is unofficially out for our galaxy A10. It can be flashed using the twrp recovery. The twrp can be flashed uising Odin.
Thanks all i will try it and let you know the outcome of the same.
