Samsung Galaxy S2 [SGH-I757M][Bell] How to root and How to install a custom rom. - Galaxy S II HD LTE Android Development

This is a guide as I was finally able to root my phone. Every time I tried to root through CF it soft-bricked with a red android and would not boot ( If your in this state, use odin and flash the stock firmware from sammoble). I am no master at flashing but I did spend days on end and this method should be fool proof. For me the other ways of flashing the galaxys2bell file did not root it.
I am not responsible for any damage you do to your phone. ( Nothing should happen but just to cover my AS)
For ROOT:
1. Download Odin3 v1.85 and flash the latest version of Clockwork Recovery HERE
2. Unzip Odin and CWM
2 1/2 . Boot the phone into Download Mode. ( Shutdown, then hold Power + Volume Down)
3. Plug in your phone and you should see that a yellow box is filled up with a COM#
4. Insert the latest version of the Clockwork Recovery in the BOOT-LOADER make sure it is ticked and flash away.
5. Remove the battery after Odin says PASS
6. Put the battery back in and hold the Power + Volume Down + Volume Up until you see it boot with letters on the screen, let go and wait for 20 seconds.
7. If it is booted into recovery restart the phone and go into the google play store.
8. Download SuperSU
9. Open the app and select "TWRP/CWM method" on the popup
10. The phone should automatically restart and go into recovery, it should install the SU binaries
11. Enjoy your Custom recovery and your SU privileges
For CUSTOM ROM:
(Have a Modem for JB)
1. Boot into CWM, make sure you have the latest version 6.00^. (Shutdown then hold the Power + Volume Down + Volume Up)
2. Wipe/ Factory Reset Option > Install a New Rom
3. Install a zip option > Locate the SD card with your ROM , GAPPS, and MODEM
4. Install the MODEM FIRST
5. Install the ROM SECOND
5. Install GAPPS THIRD
For XPOSED ( For KK or Lower)
1. Go to the Xposed's website and download the Xposed Installer (Not on the play store)
2. Go into settings and allow installation of unknown applications.
3. Install the Xposed installer.
4. Open the app and give it SU permissions.
5. Phone will automatically reboot and install Xposed.
6. Install modules and enjoy.
Rom I currently use: Slim KitKat.
I recommend you find micro-gapps for kitkat.
IF ANYTHING DOES GO WRONG just don't panic. Try and boot your phone into download mode and flash the stock Firmware.

will there be any unofficial builds of android lolipop for this device or is it done? Im just wondering because the original s2 gets a lot of support so I think this one should too.

There is no more official support for our S2 AFAIK, although in the FAQ I remember reading something about our model having the ability to flash Roms built for another kind of S2. Don't take my word as Bible, but it's possible I think. In short, no official support, but there is still hope. Check out the skyrocket model of the S2.

Hi everyone!
I'm a new sgs user.. sry for my bad english, I'm just learning it
I've just wanted to try darky's rom and it was very difficult to do from CM7 nightly.. but I'm here and my accelerometer problem is solved...
Use it on your own risk!
So here we go!
[GUIDE]
First at all download these files:
ODIN:
ODIN 1.82
The latest original firmware:
samfirmware.com I9000
At the moment I used this: I9000XXJVS.rar
A flashable kernel that supports CWM for example: Semaphore 1.9.0
The CM7 or MIUI installer zip that you're already using!
that's it
What to do?
1. Now put your CM7/MIUI installer Zip on your SD.
2. Power off your SGS
3. Use the 3-Button Combination(Volume up+Home+power button) to recovery mode..
4. Go on backup and restore and do a nandroid backup!
5. Power off your phone
6. Unpack I9000XXJVS.rar
7. Start ODIN and select the files like this
8. Go your phone to download mode(volume down+home+power button), connect to USB and click on flash button. Installing(1-2 minutes)
9. After that your phone will reboots and boots the orginal SGS Gingerbread.
10. Skip all what you can, go to the settings, display, take yout phone flat and do a horizontal calibration.
11. Power off your phone.
12. choose semaphore kernel to PDA like this (without Re-Partition!!)
13. go your phone to download mode and flash the kernel!
14. Phone will reboots, but not now! take out the battery and go to recovery mode.
15. choose install zip from sd card and select your CM7/MIUI install zip
YOUR PHONE WILL REBOOTS LIKE CRAZY but don't be afraid take out your battery and go to recovery. Try now to install the zip: "install zip from sd card and select your CM7/MIUI install zip"
*INSTALLED*
16. Go back and go to backup and restore. Restore your phone (5-10 minutes for me)
17. Reboot your phone
18. ENJOY!!
I hope it can be help. That's my first thread, sorry if i wrong.

[Q] How to flash Stock GB ROM on ICS ROM

I have ICS rom installed in my note and wanted to go back stock GB ROM.

Section (5) : Getting back to your old Ginger Bread ROM :
If your having troubles and want to go back to your old GB ROM, this is how you restore. Credits to chasmodo for the instructions.
1. download AbyssNote 3.9 kernel. It's a flashable zip.
2. put this zip on your SD Card before you try to restore your previous system
3. when you want to restore, power off your phone
4. boot into recovery (Volume up + Home + Power)
5. chose 'install zip from SD Card'
6. navigate to your Abyss kernel zip and flash it
7. go back to the Recovery start menu
8. go to advanced/reboot recovery <--- this will reboot the phone directly to recovery
9. you will discover that you now have Hyperdroid Redpill Recovery - it comes with the Abyss kernel - it's pretty much the same thing as CWMR
10. wipe cache, dalvik, do your factory reset
11. start your restore, and it will work.

If you are familiar with PC Odin then flash using PC Odin.
Download Stock GB ROM
Open Odin
Put downloaded .md5 file PDA
Put your device in Download mode
Connect cable to PC and device
Make sure "Re-Partition" is not ticked and you havnt selected any Pit file
Make sure u have installed USB Drivers for Note
Make sure your device successfully added to Odin (Yellow block with COM port number)
Just click Start
and wait for complete reboot

No, flashing back AbyssNote 3.9 + a GB kernel should work (I did a nandroid restore instead),
just DO NOT WIPE ANYTHING while on the "killer kernel", this appears to corrupt the partition table.
can somebody help me, i flashed a stoch firmware over the ics without flashing the obysse kernel, now it juh go to samsung logo and restart there, what can i do now
Try this:
1. pull out your battery
2. wait for 30-40 seconds
3. put it back in
4. go to stock recovery (volume up + home key + power key)
5. wipe everything you can (wipe cache and do a factory reset)
6. reboot system
If this doesn't help, try reflashing your stock rom and do the above after flashing.

[Q]Unable to flash Cyanogenmod from rooted I9000XXJW4

Hi,
I'm having a major issue with not being able to flash roms using clockworkmod for some strange reason.
I decided to move from MIUI rom because every time I gave it a chance when new versions came out, it constantly let me down with countless bugs and such. So, I've decided to go back to modified stock ROMs as they seem more reliable.
When I attempted to flash using clockworkmod (that comes with MIUI) it failed to apply the new (non-MIUI) ROM and forced it to go into a bootloop which knackered up going into recovery, so my only other option was to go into download mode and flash a stock ROM (I chose the latest, I9000XXJW4), root it, flash cyanogenmod and try again.
But unfortunately this did not work and now I'm stuck on the stock ROM.
I've taken a video of the exact moment it all goes wrong. Also, below is each step taken of the process.
youtube.com/watch?v=EmZAZ3DeL2U
1) Download Samsung Value Pack (I9000XXJW4) and CF-Root-XX_OXA_JW4-v4.4-CWM3RFS
2) Galaxy S rebooted to download mode
3) Used Odin3 1.85 to apply JW4_JW4_JW4.TAR file to the PDA section. Re-Partition is not checked.
4) Allowed the device to reboot to the home screen.
5) Powered off the device and booted back to download mode
6) Used Odin3 1.85 to apply CF-Root-XX_OXA_JW4-v4.4-CWM3RFS.TAR to the PDA section. Re-Partition is not checked.
7) Allowed the device to reboot to the home screen (The video begins now).
8) Launched the CWM application (with root permissions) and rebooted to Recovery.
9) Wipe data/factory reset selected and confirmed
10) Wipe Dalvik Cache selected and confirmed
11) Format /system selected and confirmed
12) Install zip from SD Card, Choose Zip from sdcard and update-cm-7.1.0-GalaxyS-signed.zip selected and confirmed.
13) Here is an extract from the log that follows before rebooting:
- Finding update package...
- Opening update package...
- Installing update...
- Checking state of BML/MTD...
14) Self-Rebooted
15) Boot-loop
Any help is greatly appreciated!
Thanks,
Andy
when it bootloops it does it cause it just flashed the kernel and its trying to run the stock rom on the cynogen kernel. so pull the battery, put it back in. reboot into recovery and flash the rom again. it should work the second time cause its using the cynogen mods version of cwm recovery. let it boot it will take a while. but that should work.
dont forget to hit thanks!

[Q] Understanding rooting - NovaFusion/CyanogenMod

So I'm new to rooting and was thinking about spicing up my old NON-ROOTED European version of S3 Mini (as in I8190). I did some research and decided to go with CyanogenMod ROM for the best stability and support. The latest build (11.0) can be downloaded from NovaFusion. The developers offer the following instructions (I'm using a Mac):
You need to download these files:
JOdin3 r1035 for OS X/Linux/Windows: download
Latest Heimdall driver for your OS: download (from official page)
Latest version of ROM for Odin from our download page.
Installed Java (on Mac you can simply install it from AppStore, if you’re Linux owner, Google how to install it on your distribution)
And then perform this steps:
Install downloaded Heimdall drivers. After installation probably you will need to restart your computer.
Unzip downloaded package with latest ROM (if it’s zipped). You should get file with *.tar.md5 extension
Run JOdin3 using Java.
In opened window, click on PDA button and select file with *.tar.md5 extension from previous step
Make sure that only Auto Reboot is selected on the left side.
Turn off your phone, and then use VOL- & HOME & POWER buttons combination.
If you see Warning screen, use VOL+ button.
You should see Android and some information.
Connect phone to computer and make sure it is detected by JOdin (it will appear as COM device). If it doesn’t, try to use other USB port.
Use Start button. JOdin will inform you that no PIT file was attached and ask if it should be downloaded itself. Agree for it. Wait until flash process will finish.
Your phone will restart, but probably won’t boot. Pull down your battery and use VOL+ & HOME & POWER buttons combo to boot into recovery.
Click on Wipe, then use slider on the bottom to let process begin.
Click on Home icon, and then Reboot -> System.
Wait for boot. Now you should have ROM installed and ready to use!
They also suggest this:
For flashing KitKat, we recommend you to install our TWRP recovery (available on Download page)!
My problem: I'm having trouble understanding which part is the "rooting" (which from what I've understood must be done before flashing a ROM) and which part is flashing the CyanogenMod ROM. Does this method include rooting? When should I install the TWRP recovery? Is it the first step to do to an non-rooted device? Is every step of getting a non-rooted S3 Mini to a rooted S3 Mini with CyanogenMOD Kitkat included in these instructions?

Rooting is not required when flashing a rooted ROM via Odin or Heimdall.
Note: CyanogenMod is already rooted.
Note2: Odin or Heimdall is not the only installation method and other methods might require you to be rooted first...

Thank you for clearing this up. What about the TWRP recovery? None of the steps in NovaFusion's instructions include using this file. Do I need it or is it something for another type of flashing method (other than Heimdall/Odin)?

Typically the first thing you want to flash a custom recovery like TWRP via Odin or Heimdall. That allows you to flash things via recovery which gives you and additional option. Not all custom ROM's you find will have and (Odin or Heimdall) option. Most are recovery only; Also most MOD's are recovery only... If you are flashing a custom ROM then I would also flash the custom recovery the ROM creator recommends... :good:
EDIT: Also, recovery gives you the option to make a full backup, which you can restore incase you don't like the ROM..

Understood. So basically after installation of Heimdall I will flash TWRP (and probably do a backup via TWRP) and then continue on with
Unzip downloaded package with latest ROM (if it’s zipped). You should get file with *.tar.md5 extension
Run JOdin3 using Java.
In opened window, click on PDA button and select file with *.tar.md5 extension from previous step
Make sure that only Auto Reboot is selected on the left side.
Turn off your phone, and then use VOL- & HOME & POWER buttons combination.
If you see Warning screen, use VOL+ button.
You should see Android and some information.

Click on Wipe, then use slider on the bottom to let process begin.
Click on Home icon, and then Reboot -> System.
Wait for boot. Now you should have ROM installed and ready to use!
Thank you so much for helping me with these beginner's questions!

No matter what i flash in odin, the result is the same: bootloop

i wonder if there is a way out of a bootloop that works no matter what, as long as you can enter download mode.
after reading for 3 days and flashing everything i could (flashing stock ROM, WIPE_I8190.tar.md5, PARAM_I8190.tar.md5, "LeFreu" I8190 серв. укр) it all gave me the same result: bootloop.
i made a back up before flashing a custom ROM (Dmod V6 and Virginity V3 as they seemed like the best ones) so if any of u help me access CWM recovery or TWRP i could do a restore and make my phone work again.
NOTE: the only way i managed to use CWM recovery the first time was rooting with odin "I8190XXALL2_I8190OXXALL1_HOME_rooted_by_avicohh" and then downloading rom manager from the playstore
the attached screenshot shows my device info from factory, can anyone help me restore my phone?
gimmesansa said:
i need serious help.
i have a galaxy s3 mini gt-i8190 and im stuck on a bootloop
i bought it in new sealed condition and it came with this firmware (see attached screenshot)
and when i tried to update it a window popped saying that my device was modified and that software update were not available.
i decided to root my phone so i could install a new rom.
i downloaded all the software i needed including drivers dor the usb samdung devices and enabled usb debuging in developer options
then i used odin to flash I8190XXALL2_I8190OXXALL1_HOME_rooted_by_avicohh
then i tried flashing custom recovery via odin also
everything went normal but custom recovery was not sticking, meaning no matter what type of custom recovery i flashed (twrp, cwm) i ended up having 3e stock recovery.. (NOTE: the 3e stock recovery before AND after flashing rooted ROM, had always a broken android on the floor with an exclamationg sign in its chest) so i tried another method:
i downloaded root checker from the playstore and rom manager. after checking i was rooted (wich i was) i flashed cwm recovery and succesfully was able tu boot into cwm recovery. i did a back up in both, internal storage and external sd, and procedded to flash Dmod V6. i followed the aroma installer and when it finished i selected reboot system now and got a bootloop.
i entered in cwm recovery and did a restore. did a full wipe (data, cache and dalvik) and tried flashing another rom: virginity ROM. followed the aroma installer and selected reboot system now, the result was bootloop.
when i was trying to do another restore the recovery told me that the system would try to flash stock recovery again and i choosed to keep the cwm recovery.
at this point my phone was able to turn on and boot normally. tried again to flash via cwm the virginity rom and got a bootloop again. so i went to do another restore and this time i choosed diferently (flash stock recovery) and when the restore ended i selected rebbot system now and got a bootloop AGAIN.
now i cannot enter CWM recovery (i guess that is obvious because i choosed to flash stock one)
i have readed 3 days now and tried everything that the forums say: flashing stock firmware, flashing WIPE_I8190.tar.md5, flashing PARAM_I8190.tar.md5 and still ended with a bootloop. tried flashing I8190 серв. укр (LeFleur) and nothing, absolutely nothing works.
i even downloaded Unified_Android_Toolkit_v1.2.8 and tried to flash stock firmware but nothing seems to work. all my phone does is bootloop, and boot into download mode.
can a serious developer help me solve this? im about to give up.... and that seriously affects me because im not a quitter.
any help would be greatly apreciated...
