[Galaxy Y GT-S5360 and Duos 6102 Q&A, Help & Troubl] mai77:
HOW TO INTSTALL MT-2.5 latest , which is build #206 as of Oktober 2012

make sure you have the following 3 files:

1-EliteKernelModules.zip = module installer for CWM

Ext4_Converter-signed.zip = build #206 kernel installer & ext4-filesystem-converter, for CWM

pda.merruk.tar = build #164 kernel with integrated CWM, for to flash with ODIN

-----------------------------------------------------------------------------------------------------

1. install MT-2.5 build #164 with ODIN: flash pda.merruk.tar

2. in CWM: create a backup (for use in step 6. THIS IS NOT OPTIONAL !)

3. install elite modules using zip in CWM

4. in CWM menu, choose to create "error report"

5. install latest kernel (use the "all in one"-file) build #206

6. CWM menu "restore advanced": restore system, data, cache but not kernel, from your backup data in step 2.

7. S7 = Step 7 = verify: look up "build #206" string in menu: settings --> about phone --> kernel version

8. optionally root your SGY

THIS WAY I SUCCESSFULLY INSTALLED Kernel: MT-2.5 #206 "de luxe"

after 1. you may get FC and non rooted SGY for some odd reason (happened over here, carry on regardless ! )

so you better UNmark "reboot" in ODIN and go straight into CWM by holding UP+HOME+POWER combo, without even fully rebooting into AndroidOS.

Also, this saves time.

after 3. one gets stuck in boot logo, if step 6. is not being carried out, but CWM was still accessible. modules in place.

Only if you restore your backup in step 6. from step 2. you will be able to boot fully !

do step 5. and step 6. in one go ! do not reboot after step 5. !

in step 5. be prepared to be given instructions ("restart now!") which you may not want to follow. Instead of restarting, you should restore first, else you get stuck.

in step 5. the installer says Ver. 2.0 when it is Ver. 2.5, just a cosmetical thing.

there is, however, a much simpler way to do it,

which is without ODIN. Also this is a fast way to rescue your system when it is screwed up. so keep these files on your SD card.

assuming that you are on stock ROM follow these steps:

1. install MT-2.0 build #103 with KernelUpdate-zip in CWM

2. in CWM: create a backup (for use in step 6. THIS IS NOT OPTIONAL, cuz of partition delete in step 5. )

3. install elite modules using .zip-file in CWM

4. in CWM menu, choose to create "error report" (optional)

5. install latest kernel (use the "all in one"-file) build #206, then choose: advanced / reboot recovery

6. CWM menu "restore advanced": restore system, data, cache but not kernel, from your backup data in step 2. (NOT OPTIONAL!)

7. S7 = Step 7 = verify: look up "build #206" string in menu: settings --> about phone --> kernel version (optional)

8. optionally root your SGY

I tested it, it works like a charm !!

for this method you need these files:

boot.img out of Kernel-MT-2.0 .zip file (in post #1 in main Merruk thread http://xdaforums.com/attachment.php?attachmentid=1053569&d=1336694938 )

KernelUpdate.zip

madteam-CWM.zip (trusted old temporary CWM)

Kernel-MT2.5 #205 install & converter pack, see above

Elite-module-installer (like above)

if you installed a "new" SGY system from scratch ( i.e. "factory data reset") or better, you may want to install 3 "essentials" in this proper order:

:laugh: 1. root the SGY with SuperUser.apk including latest binary with an UPDATE.ZIP inside "Android system recovery" // NOT ALWAYS NECESSARY UNDER MERRUK KERRNEL; MT2.5 comes pre-rooted (I suppose) !

:laugh: 2. run & install StEricsons's BUSYBOX offline-installer .apk (don't use the installer by JRummy16, because JRummy16's one is an ONline installer)

:laugh: 3. install Link2SD.apk, which needs both of the above as a prerequisite. Remember to prepare your SDcard with a secondary ext2-partition beforehand !

caveat emptor: to be perfectly honest: Link2SD was tested on stock ROM only by me. I cannot say for sure whether you have the same storage savings under MT2.5, but I will find out later.
