UPDATED 2013-09-06 (NEW AND EASY WAY with links to GB/JB FULL 3-parted Firmwares)
UPDATED 2013-09-05 (I8160PXXMG2_I8160POXXMG2_624MB_MULTI_ROOT)
UPDATED 2013-07-26 (USB Debugging is not needed for working with ADB in Android System Recovery)
UPDATED 2013-07-24 (I8160POXXMF1_MULTI & I8160POXXMF1_MULTI_ROOT)
This GUIDE is for those who own an GT-I8160P and flashed it to an GT-I8160 (non-P) with one of the leaked JB FW MB2/MB4 and/or MC8 or mixed MC8/ME1 or GB RUS LK6 (3-Parted).
This will bring back your FULL GT-I8160P with incl. Baseband, Bootlogo, Model info in Recovery, etc!
Without any Counter increase or unofficial custom Binarys!
Old way (NOT recommended anymore because to difficult for some - but still working)
Whats needed:
- Your ROOTED GT-I8160P has an active and working IMEI currently! This is not a guide to bring back IMEI!
- USB-Debugging is activated! - Not needed for ADB
- You know how to ROOT your Phone! GB or JB having different methods! - Good rooting HOW-TO [http://forum.xda-developers.com/showpost.php?p=39799320]
- Installed ADB and basic knowledge in ADB (I recommend installation to C:\ADB>)
- Installed ODIN 3.07 and basic knowledge in flashing with ODIN 3.07
- Knowledge how to enter Android System Recovery and ODIN Download Mode
- External SD-Card (everyone should have one if you own a 8160P)
- Phone is connected with USB cable to PC
- some patience
Which Files are needed:
- I8160P_DBT.rar (Contains I8160P_DBT.bin) [http://d-h.st/Q4L]
- ANY FULL original GB or JB Firmware for GT-I8160P [http://www.sammobile.com/firmwares/1/?model=GT-I8160P&pcode=0#firmware]
Optional Files
- I recommend to use JB FW I8160PXXME1_I8160PDBTME1_DBT [http://www.hotfile.com/dl/222919379/f5c8dfe/I8160PXXME1_I8160PDBTME1_DBT.zip.html]
- 1st TIP: Made by me MULTI-CSC FW I8160PXXMF1_I8160POXXMF1_MULTI [http://d-h.st/TNo]
- 2nd TIP: Made by me MULTI-CSC Pre-Rooted FW I8160PXXMF1_I8160POXXMF1_MULTI_ROOT [http://d-h.st/MeA]
- 3rd TIP: Made by me MULTI-CSC Pre-Rooted FW I8160PXXMG2_I8160POXXMG2_624MB_MULTI_ROOT [http://d-h.st/TEA]
- FULL_NAND_BACKUP_ADB.rar (ADB with easy to handle FULL BACKUP and FULL RESTORE script) [http://d-h.st/Efj]
Further Information
- If you go back to GB and do rooting with Kernel than your Counter will be increased!
- If everything went well your Data remains untouched! (If you did not Wiping Data and Factory Reset)
- BUT: Wiping Data and Factory Reset is still recommended after you finished HOW-TO!
- Keep the Backup of CSPSA_FS and MODEM_FS + EFS save! This is your Serialnumber, IMEI and MAC adress!
- Use ALL ADB commands from your PCs CMD - Command Prompt (e.g. C:\ADB>) while your Phone is in (stock) Android System Recovery
- If you got ADB message: mount: Device or resource busy - Don't care about it! Your SD-Card is already mounted! Go ahead!
- Its sometimes needed to let the SAMSUNG Android ADB Interface install its driver new. That happens if you came from JB and go to GB and vice versa.
Delete old ADB Interfaces in System Control on PC [if needed "Show hidden devices"] but do NOT delete Drivers!
De- and Replug USB that PC can install new ADB Interface. Only do the driver reinstallation if during ADB commands your Phone is not recognized.
Disclaminar:
I'am not responsible if you brick your phone. Keep in mind that we do some critical commands for partition copy/write here.
If you are NOT familar with ADB or ODIN please don't try this at home!

Optional
- Before you start I recommend to make a FULL (incl internal SDCard) Nand-Backup of 3,68 GB (3.959.422.976 Bytes) to external SD-Card
- This Will take 6-7 mins - could be more if your SD-Card is slow.
A) Enter stock Android System Recovery
B) Mount SD-Card
Code:
adb shell su -c "mount -t vfat -o rw /dev/block/mmcblk1p1 /sdcard"
C) FULL Backup:
Code:
adb shell su -c "dd if=/dev/block/mmcblk0 of=/sdcard/fullbackup.img bs=4096"
Option: FULL Restore - If you want to go back to old state of your Phone
Code:
adb shell su -c "dd if=/sdcard/fullbackup.img of=/dev/block/mmcblk0 bs=4096"
Here we go:
1.) Move File I8160P_DBT.bin from Archive to root of external SD-Card
2.) Enter stock Android System Recovery
3.) Open Command Promt (CMD) to you ADB folder (e.g. C:\ADB> )
Leave the CMD ADB Window open. We need it again.
4.) Mount external SD-Card
Code:
adb shell su -c "mount -t vfat -o rw /dev/block/mmcblk1p1 /sdcard"
5.) Backup CSPSA_FS and MODEM_FS + EFS to external SD-Card
Code:
adb shell su -c "dd if=/dev/block/mmcblk0 of=/sdcard/CSPSA_FS.img bs=4096 skip=384 count=384"
Code:
adb shell su -c "dd if=/dev/block/mmcblk0 of=/sdcard/MODEM_FS_EFS.img bs=4096 skip=1024 count=6656"
6.) Write I8160P_DBT.bin from external SD-Card to your Phone
Code:
adb shell su -c "dd if=/sdcard/I8160P_DBT.bin of=/dev/block/mmcblk0 bs=4096 count=17664"
7.) Go directly into ODIN Downloadmode (Hold the 3 Keys as long as needed directly out of Android System Recovery)
8.) Flash FULL original GT-I8160P Firmware with ODIN 3.07 (PDA)
9.) After ODIN rebooted let your Phone boot completely! activate USB Debugging
10.) Root your Phone! (Keep in mind: JB and GB having different methods!)
11.) Enter stock Android System Recovery
12.) Mount external SD-Card
Code:
adb shell su -c "mount -t vfat -o rw /dev/block/mmcblk1p1 /sdcard"
13.) Write saved CSPSA_FS and MODEM_FS + EFS from external SD-Card to Phone
Code:
adb shell su -c "dd if=/sdcard/CSPSA_FS.img of=/dev/block/mmcblk0 bs=4096 seek=384 count=384"
Code:
adb shell su -c "dd if=/sdcard/MODEM_FS_EFS.img of=/dev/block/mmcblk0 bs=4096 seek=1024 count=6656"
14.) Reboot and be Happy that the FULL GT-I8160P with working IMEI is back in Town!
Without any Counter increase or unofficial custom Binarys!

Here we go:
1.) Move File BACK_TO_THE_I8160P.zip to root of external SD-Card
2.) Install CWM Recovery
- For GB: Flash I8160XXLL2_CWM_5.0.2.6_ANT.tar.md5 from archive with ODIN as PDA (This is the CWM Kernel for GT-I8160)
- For JB: Install CWM_6.0.2.8.zip from Android System Recovery. Move this file before to root of external SD-Card (This is the temporary CWM Recovery for JB)
3.) Go into CWM Recovery
- For GB: Press following keys together (as long as needed): VOL UP + HOME + POWER
- For JB: CWM is available right after you installed it from Android System Recovery (Enter Android System Recovery also with VOL UP + HOME + POWER)
4.) Install from CWM Recovery the file BACK_TO_THE_I8160P.zip and follow the instructions on the display
- This will also save your EFS / MODEMFS / CSPSA partitions to folder BACKI8160P on external SD-Card - Keep those files save.
5.) Flash FULL 3-parted GB or JB Firmware (PIT as PIT / CODE as PDA / CSC as CSC)
- This is also instructed in the script - You do not need it twice of course.
- Set ODIN as mentioned here: [HOW-TO] Go back from JB to GB on GT-I8160P (ACE 2 NFC)
6.) OPTIONAL: Flash any GT-I8160P Firmware of your specific country
That was easy, isn't it?
If you are Happy with this please push Thanks! :highfive: - Or if you just like my "Back to the..." Image LoL

Can this be used to come from JB (the P version) back to GB? It would help a lot of people since many people who had official update through Kies (PHE and XEZ CSC) have only 482 MB of RAM. (I would try it if I wasn't such a *****... but I just got my phone back from service yesterday since it was hardbricked )

---

This will go over GB RUS FW (this will bring you 550MB) and then (after the other suff) we flash I8160PXXME1_I8160PDBTME1_DBT (you get also 550MB)
If you can use an GB FW of I8160P instead of JB could be possible - Logically it must work - BUT THIS IS NOT TESTED BY ME...
Personally I don't see any reason to go back to GB but I understand your wishes.
I think I'm the best choise to test this (because the RIFF Box is lying around here :good
I will test this with the latest GB 8160P DBT - I8160PXXLK2_I8160PDBTLK2_DBT and let you all know.

---

AGAIN: Success :victory:
Works also with GB I8160PXXLK2_I8160PDBTLK2_DBT
Be sure that you have Pre-Rooted Version of it or the rooted system_rooted.tar.md5 and csc.tar.md5 available....
I don't know if this will work with the Kernel-Root method - I do not test this.....
So it's also possible to go back to FULL I8160P with GB!
With this way we have an access error to DBT CSC - And Multi CSC will be installed. But this is not a problem!
This leads me to the opinion that this might work with any other original FW of JB or GB of 8160P
Feel free to test this and report please if you used another FW.... Please keep in mind that you need to root it to push CSPSA_FS back....

---

So in which step should I flash the GB DBT ROM? (step 2 or 9 according to your guide)?

Click to expand...
Click to collapse
Step 9 (of course)
Please read it again and try to understand what we are doing here...
Main Key is to save the CSPSA_FS from a working IMEI FW.
Then we push the first 70 MB of an 8160P DUMP (to get the 8160P back technically)
This is actually the most "risky" part. But you'll have access to Andriod recovery and Downloadmode anyway. So who cares :angel:
Then we flash the 8160P original FW.
After that we write saved CSPSA_FS back to get IMEI.
The Rest is Rooting, ADB Drivers installing and getting back 550MB (with 3 parted RUS FW)
If you like to have another FW combination (to have 482/550/624MB) feel free to test it.
I posted this HOW-TO for the most recommended way! 550MB with JB in my opinion.
BUT: If you want to stay with your current RAM configuration - and only get back the 8160P - Then you can leave 1 - 3 and start directly with Nr. 4.
It might also work if you save the CSPSA_FS before you do the DUMP and FW flashing (NOT tested). But I decided to write this HOW-TO that everyone has the same initial situation...

---

Okay, my last question
Lets say I'm on P-version JB and have 482 RAM. I want to have 550. The fact that I have only 482 is caused by the new SBL (normal.bin) from XEZ ME1 JB ROM. (the DBT JB Odin package doesn't contain the normal.bin and because of that it has 550 RAM if you flash it over GB) In order to get 550 I need to flash the GB SBL.(most probably ) Can I just do this?
1. backup CSPSA_FS
2. flash the I8160P_DBT.bin you posted
3. restore my CSPSA_FS
Is there a risk of bricking my phone? (Except typing wrong dd command.)

fifo, fifo, fifo... - If you what to have 550MB and JB why you didn't do it as written in the HOW-TO?
This I8160P_DBT.bin is from an GB Phone! Therefore I think the most secure way is to write this to an GB FW.
And in order to get back 550MB for all the best way was to use the GB RUS FW (3-parted).
I can't say exactly if your way will work. What I can say is that during the whole testings with this 70 MB BUMP (if you flash it completly) I got never got HardBrick...
But what do you what me to say? Your Phone will never be Bricked again? I can NOT promise this! I hope you understand this.
AND: Please do not type the commands! Use Copy&Paste. STRG-C for coping the command from the HOW-TO and right mouse button and insert to paste it to ADB window (I can't belive that I'm writing this here )

One question: After you flash the JB rom do you have valid imei without the 13th step (CSPSA restore) or you have to flash CSPSA to show the correct imei even if with LK6 was ok ?

---

Thanks for this great guide!
Just one question, whlie I am mounting the SD card, cmd writes that "mount: Device or resource busy", but when I do backup, I´ve got a 3,69GB fullbackup.img there, so what am I doing wrong if something..? Thanks in advance.
P.S.: SU rights are allowed for adb in phone.

No - After JB flash the IMEI is NOT there. If this would be so then we didn't have this whole trouble :laugh:
Only after CSPSA flash! And CSPSA of GB works on JB!
[EDIT] I konw this is strage because LK6 RUS has also an CSPSA. And the IMEI works after flshing this... Could be that this CSPSA of this LK6 has an emty part in it?! That is one of my next plans to check/compare unflashed CSPSA LK6 with flashed working CSPSA.
But it seams that the step over GB RUS is not needed (some futher tests to go) - Main Key is the to save CSPSA from an working IMEI phone, flash the DUMP of 8160P, flash complete FW and write CSPSA back.
After I did some furthr tests I will adapt the HOW-TO. But up to now this works like I've written it.

If it say "mount: Device or resource busy" then your SD-Card is already mounted and its OK!
ARH! Its 3,68 GB (3.959.422.976 bytes) - You are right!!!! LOL Will correct HOW-TO! :good:

Thanks again mate, I´ve got a fully working i8160P with IMEI and everything :good:

If you have local restrictions with uploaded.to please wait until Monday - After I updated the HOW-TO I will move the files to DEV-HOST. This seams to more stress-free for most Users.

Click to expand...

I'm not sure how but I managed to get 624MB RAM on my i8160P
I was running XEZ JB ROM with 482MB RAM but wanted to try CM10, so I backed up my ROM in CWM, changed some lines in build.prop (otherwise the CM won't install), went to CWM, full-wiped, formated /system, installed CM10 and GApps. The phone still had 482MB RAM with CM10 but it was fast and smooth. After few days I wanted to go back to stock Samsung ROM, so I went to CWM, restored my backup, booted up the phone and BANG - there was 624MB RAM.
I hope you'll find out why this happened.
BTW I was using this CM10 by dh.harald.

Thx for this info! Flashed recently (for testing purposes) the MF1 (from 8160) on my 8160P (as it was an still an 8160).
This gave me also 624MB. Without any repartionering.
Knisperingo had his 8160P at the Samsung Service (as it was HardBricked long time ago). They changed the complete PCB and now he has also 624MB with an 8160P! Never heard that before!
I really don't know what this RAM is all about But lets go back to Topic. There are many other threads which are talking about this never ending story of 482/550/624 RAM...
This for instance: http://forum.xda-developers.com/showthread.php?p=42075864

I would try to format system/data and wipe cache...In Recovery Mode... If not already done.
And flash the FW again...
If this did not help you could try to format the partitions with the temporary CWM 6.0.2.8
http://forum.xda-developers.com/showthread.php?t=2141395
Menu MOUNTS AND STORAGE
Format SYSTEM, DATA, CACHE, PRELOAD, EMMC
BUT NOT SDCARD!!!! :angel:
After this your phone will not start anymore properly. But this is normal because of formated partitions
Then flash via ODIN again.....
The next start will take longer than normal....
