Introduction and few comments re: ICS / rooting

Firstly, what a great forum. I have dabbled with my phone purely on what I have gleaned from here, so keep up the great work.
I have viewed for quite a time but it is a pleasure to make my first post, so go easy on me.
I am a total newbie when it comes to phones although I have a lot of experience building PCs for many years. I have an unbranded S2 (prev XEU) which I updated with ICS OTA a few days ago. I am now on LPS. I then successfully rooted using Rachmat’s work [GUIDE] ROOT/UNROOT Stock ICS Firmware without flashing unsecure kernel), which was a breeze to do (apart from initially putting it in download mode instead of recovery and wondering why I couldn’t get any further!!).
I have since installed Titanium Backup and frozen a number of apps.
I want to share some of the problems which I have experienced after updating to ICS:
- I get the wifi problem where connectivity is suddenly lost and necessitates a reboot. After a reboot the battery level dramatically drops. I checked the router (VM Superhub) and strangely it had defaulted to factory settings. I have a LAN which runs well with 2 wired PCs, 2 laptops on wifi, 2 iPod Touch and a BB Playbook – I had to set them up again after reconfiguring the router. Needless to say, the wifi problem still exists and I have to reboot the phone every now and again.
- A strange problem with my internal SD storage – before updating I had about 9gb full which included a number of videos, etc. Following the update it still showed 9gb but my videos were gone and the USB storage folder showed 0kb. Adding up what I actually had only amounted to about 4gb and I had to erase the internal SD to get my space back.
- Battery consumption is still very poor – I had not noticed any difference using ICS. I still only get about 10 hours from a full charge if I am lucky, with a moderate amount of use. I have stopped auto-sync for everything, dimmed the display as much as possible and various other tips and I hope there will be an improvement. I have started using Juice Defender again although I am not convinced on that one.
Rooting has made no difference to the wifi issue and I will reset the router and start again when I get time tomorrow.
Thanks again

I too used Rachmat's quick and easy guide on how to root & unroot ICS firmware and found it so simple and great to use. I have flashed a number of different custom ICS roms since rooting XWLP8 and my counter has not gone up at all and there is no yellow triangle. I recommend this method for anyone using ICS.

Did you wipe everything after updating to ICS?
About battery dropping after reboot, it's normal (at least I didn't find a fix).. I mean, it's normal that the battery indicator shows a wrong information.. if you just let your phone, you will notice the indicator going up without charge.. after reboot sometimes the battery indicator doesn't show the real battery level.
And about your battery lofe, you should be more specific.. like how many time of screen on, calls, if you are using 2G, 3G or wifi, if you are playing games or videos etc.

I had WIFI problem with the LPQ and LPS update (last saturday OTA) fixed it.

After updating to ICS I erased my internal USB data which solved the problem where my free space was reported inaccurately.
I didn't do a factory reset.
With regard to phone/battery usage, I tend to use it for browsing, email and occasionally music. Don't play many games on it, especially CPU/graphic intensive games. Very occasionally I will watch a video but not many and I fully expect the battery to discahrge quickly.
To give an example, this morning at 09:00 my battery was at 83%. It is now at 41% some 5.5hrs later. Screen is 0% display and has been during this time, all syncing is off, wifi has been on perhaps 10-15 minutes max, no GPS or bluetooth. I have browsed the web, checked emails, etc - used the phone for approximately 30 minutes in 5.5hrs. by the way, JD is showing x2.17.
Thank you

Are you with CWM recovery? If so, do a nandroid backup first and then wioe everything. Wipe data, cache and dalvik cache.. this won't affect your sd card (both internal and external), but will set the system as default, with no apps or data (such as google accounts).
When you change your system (specially in your case, when you moved from a GB to iCS rom) you should wipe everything.
Also, about battery life, only after 3/4 full cycles you will be able to see how it really is.
But since I've never used stock kernel, can't say much about it, but Abyss is being a great kernel for me.

Do you refer to the CWM.zip file I put on the external SD card from Rachmat's tutorial?
If so, I still have it there. Do you mean go into recovery, install CWM.zip from external SD, and Nandroid backup will be an option?
thanks

Yes, you can use this CWM.zip, you will find an option for backup (there won't be mention to nandroid, so don't look for it).
Sent from my GT-I9100 using Tapatalk 2

Okay, just so that I get this straight...
I go into recovery
Install CWM.zip from sdcard
backup using backup/restore in recover
Wipe data/factory reset from recovery
Wipe cache partition
Where is dalvik cache? Also, will not the factory reset put me back to GB 2.3.4?
Sorry to appear dumb but I just want to get it clear in my head.
Thanks again
Tim

Dalvik is under advanced in cwm.
You will do everything under cwm, ok? Enter normal recovery, apply cwm.zip and do everything in cwm recovery.
No, it won't take you back to gb.

Sorry, just one more thing. Once I have reset/wiped using recovery do I just restart my phone and use or do I have to restore the backup?
Tim

Just reboot. The backup is just for the case of something going wrong.. the nandroid backup backs up everything.. I mean EVERYTHING.. so if you wipe everything and restore the backup it will be as if you didn't wipe anything.

I cant get this method to work despite numerous attempts. Not sure where I am going wrong.
It all appears to work okay (Superuser is in the Apps menu) but when I run Root Checker it says it is not rooted and this does appear to be true because the latest Total Recall will not work either.
Maybe someone else could try Root Checker and confirm that they are actually rooted.

Glad it worked.
I suggest you to try other kernels... but remember, when you flash other kernel, give it some time untill you make conclusions, since, as I said, 3 or 4 full charges are needed to settle things up.

All you have to do is install cwm.zip onto external SD card and install SU-Installer-Signed.zip onto your internal SD (I tried it on external but CWM didn't recognise the file). Reboot into recovery, then choose install update from SD card and install cwm.zip . Once that's installed click on install zip from SD card and install SU-Installer-Signed.zip and once that's installed just go back and reboot.
If Superuser is in your apps list then I'm fairly certain you're rooted. I did exactly what you did and was able to install custom roms, overclock and every app that needs root (Titanium Backup, Rom Manager CWM) asked for permission and it was granted. Give it another try and see how you go. :thumbup:

The need to wipe battery stats died with Android FroYo (or maybe it was already back at Eclair?). When you charge your battery to 100% and pull the cord, then the stats are reset.

Battery Calibration

Hello all
My phone dies when 6% left and doesn't charge over 98%. I observe that this weird thing started happening after i restarted my phone while it was getting charged through AC.
So, now how do i go about it? Do i need to calibrate it? If Yes, What is the best procedure to do so? Please help me as my nexus is 2 weeks old and don't want to see it in this situation.
Thank You

There are some apps that do it for you, but I prefer to do it manually.
1. Charge your phone untill 100
2. Download Root Browser
3. Disconnect it and reboot
4. Charge it till 100 again
5. Go to Root Browser and then open data/system folder.
6. Unplug your phone
7. Delete batterystats.bin file
8. Let it drain till 0%
Calibrated!!

GUIDE: How to Install Marshmallow on G925I coming from Lollipop ROM

I have seen many people on the ROM forums saying that you can't install Marshmallow ROMs on a G925I, or asking how to install.
Well I can say that yes it is possible and yes it is really straight forward and easy to do.
So I have decided to do it myself (prior to this I was also on Lollipop ROM) and took down the steps (literally step by step) to help others.
Please note: This will trip Knox.
What you need first:
1. Official Stock Marshmallow ROM for G925I
Download from here
2. Odin (I used 3.10.7)
3. Arter97's TWRP 3.0 recovery fro G925FI
Download from here
4. A custom ROM (I used Pure Stock ExtraLite Rom). Copy to your phone.
Steps:
1. Backup (EFS, nandroid, I also copied my files like photos, documents, etc to my PC)
2. Turn off device
3. Power on device directly in recovery (volume up + home + power)
4. Plug USB cable to PC and device
5. Go to Mount and enable MTP
6. Delete folders you don't need (I only kept DCIM, Bluetooth, downloads, documents, etc)
6.1 In DCIM, delete .thumbnails. I also deleted all the other folders with a . in front of them
7. Disable MTP and pull the USB cable from your device
8. Go to Home and click on Wipe
9. Swipe to factory reset
10. Click back and then advanced wipe
11. Select dalvik cache, cache, data and system (no need to wipe internal)
12. Swipe to wipe
13. Turn off device
14. Power on device directly in download mode (volume down + home + power)
15. Press volume up to continue in download mode
16. Start ODIN in administrator
17. Connect USB cable and make sure your device is recognised by ODIN
18. Click on AP and select G925I Marshmallow Stock ROM
19. Click start (it will take some time to flash)
20. Once finished, let it boot into new Marshmallow Stock ROM
21. You can unplug the USB once it is booting
22. Once booted, quickly setup your phone (probably dont need to but i wanted to see it first)
23. Once booted, turn off device completely
24. Power on device directly in download mode (volume down + home + power)
25. Press volume up to continue in downlod mode
26. This time uncheck auto reboot
27. Connect USB cable and make sure your device is recognised by ODIN
28. Click on AP and select Arter97's TWRP 3.0 (.tar.md5)
29. Click start
30. Once finished, unplug the USB cable from device
31. Press volume down + home + power until phone turns off (screen black). Release the keys and immediately press volume up + home + power to boot phone into recovery
32. Agree to TWRP's modification of the system message (swipe to allow)
33. Plug USB cable in device and click on mount
34. Once again delete files you don't need (folders with a . in front of them)
35. Disable MTP and unplug USB cable from device
36. Go to Home and click on Wipe
37. Swipe to factory reset
38. Click back and then advanced wipe
39. Select dalvik cache, cache, data and system (no need to wipe internal)
40. Swipe to wipe
41. Go to Home and select Install
42. Select ROM and swipe to flash
43. Reboot once installation is complete
44. Enjoy!

Yes it should work. That is the build that I flashed to switch to Marshmallow from Lollipop.

Thanks, was looking for the instructions, just to make sure and will do it soon and update on the result.
UPDATE: Worked like a charm ... thanks. BTW, trips KNOX for those who cares.

Flashing anything not signed by Samsung like a custom recovery, kernel or ROM will trip Knox. Rooting also trips Knox.

Knox for me was already tripped before flashing MM but yes this will trip Knox

Awesome tutorial, very easy to follow indeed.
I however, instead of downloading a custom ROM fom XDA decided to download the stock Nepal 6.0.1 from sammobile. Since installing that ROM I have noticed very very poor battery life. Almost losing 5% of battery every 30 minutes SoT, this compared to losing 1% per 30 mins of SoT back on stock 5.1.1 Australia XDA.
Would anyone be able to shed some light on this at all? Maybe a fix? Do you know of a better custom MM ROM with better battery life?
Thanks

Well that's what I did. I downloaded the stock MM ROM from sammobile in order to get MM boot loader and modem. And then was able to use a custom ROM.
Not wanting to be rude but are you sure you have your stats right? 1% of battery loss per 30 minutes of SOT is impossible.. that means you'll be getting 5 hours SOT per 10% battery loss..
Right now I'm sitting on 90% battery life with a SOT of 30 minutes with hotspot on, browsing the internet, XDA and facebook.. battery life should get better but in the past few days I've been getting over 4 hours SOT per cycle. Which is roughly what I got on LP.

I'll admit the 1% per 30 mins SoT was a tiny exaggeration/estimate, but not far off.
I noticed the poor battery this morning when I woke up. I took my phone off charge (100% at the time, after an ~8 hour charge), I muted some alarms and put my phone back down, roughly 30 minutes later I got out of bed, checked my phone and noticed it was down to 96% without even using it.
As I've used it more and more through the day (as my charge gets lower) I am noticing an improvement in battery discharge so I guess I'll just let it go flat and give it a fresh charge and go from there.
I may just be focusing on the battery percentage more now because, new firmware/features ect.. But I still feel like I am losing 3-4% more now then I was on Lollipop.
But just to clarify, using the Nepal ROM on an Australian phone wouldn't be draining battery would it? I can't really think why it would, but worth asking.

I believe this is because sometimes your phone may want to boot straight into the firmware after flashing certain things. Such as with installing TWRP, TWRP needs to finish installing by booting into recovery after flashing, and not into the firmware.
Pardon me if this isn't correct.

Only reason I ask is I tried it both ways of letting it reboot and not (by Editting the Odin.ini file) and their was no difference other than I had to manually reboot when auto reboot was off (which was annoying!)

Did you try rebooting into recovery after instead of booting into the firmware? Also you can uncheck auto reboot within Odin, you don't need to edit the .ini file.

One question: can I get to install the marshmallow stock rom only following the instructions 14 to 20? I am not interested to wipe data (I haven´t done it the previous times I have done it in other mobiles) and I don't want to install a custom rom
I'm feeling curious, in this case you don't need to install it rooting the device in first place?
Thank you!

If all you're doing is flashing the stock MM ROM then yes, you should be fine doing steps 14-20. Generally, when flashing stock ROMs you wont lose any of your data (images, media, documents..) also there is no need to wipe your phones data, but I would still recommend making a backup just in case something does go wrong.

Complete wipe and flash firmware?

Hi,
Could someone please tell me, how do i completely wipe the current firmware on my phone and flash a fresh new rom on it to make the phone totally like new and no cache or so of previous remains.
I have worked with ODIN app and i did install a few firmwares on it through ODIN. But the thing is, i feel old files remain. Correct me if am wrong.
My battery life is very bad. So i am trying to find a solution if any.

After odin flashiing the proper firmware for your phone's model
do a factory data reset under the phone's settings.
Settings>General Managment>reset
Click on "reset" and follow the prompt.
Doing that will make your phone just like it was when it was new.
Good luck, have a great day!

Yes it's normal especially after flashing fresh new firmware.
It takes about 3-4 complete charges to get more of an accurate
reading of the battery's hourly power consumption starting from
a fully charged battery.
