best way to 7.8?

Hi - I'm currently on 7.5 and I've unlocked using Chevronwp7 and have 'internet sharing' working. I want to upgrade to 7.8 but I do not want to loose my unlock and 'internet sharing'. I believe if I use the Samsung 7.8 I will screw myself - so if I do the following I'll get the Microsoft 7.8 and all should work? Is my understanding correct? Here is where I planned on getting 7.8:

there is only the MS 7.8, Samsung have a firmware that will firstly clear all your ICS settings, and secondly disable the ability to install the dev unlock. however, ICS can be enabled, and so long as your unlocked BEFORE applying the Samsung firmware you can remain unlocked. you can also search the WP7 forum for a newer solution that should help you no matter what you do

easy way to 7.8
Thanks - today I used the process outlined here to get to 7.8:
http://www.windowsphonehacker.com/articles/want_windows_phone_7.8_now_try_this_easy_tool-01-31-13
This tool saved me a lot of time as I was way back on 8107. My unlock and working ICS were still fine and I was on 7.8
Also, on my wife's focus s.. I unlocked it today using the process listed here (and then turned on ICS):

Were you able to get internet sharing to work afterwards? I can't seen to get it to work.

root tools or winTT will work, you just need to get them installed and functional

Just got a brand new Focus S in the mail today.
Plugged it into the computer. Let it do the updates. Went through the process of the 2nd generation Interop Unlock successfully. Used the tweak in WP7 Root Tools to enable internet sharing and got the same message.

In the above thread, does this method work with the stock sony Xperia T firmwares
please can you post your firmware version (stock only, no cm, no aokp or custom roms) and let me know

Basically I want to access my wifes phone and check her messages as she has been acting weird
I tried the service menu trick on her phone but it didn't work which means her phone has more up to date firmware i believe

Just tried that for you, it didn't work; the Emergency dial screen wouldn't accept the *#*#73556673#*#* code.
The lock screen WAS disabled whilst the Demo was active but as pressing the power button to wake the screen was immediately rerunning the Demo I'm sure that would get noticed. (Xperia T firmware 9.1.A.1.141).
Might have time to test out the 2nd link you posted later.

1) Did the demo run?
2) Did you then press home button to go to the home screen?
3) Did you then bring up dialer and type in the demo code again to disable the demo?

In the video when the demo is running he taps it to bring up the home button, did this work on yours?

1) The Demo ran when the phone was already unlocked and I typed in the code from the dialer - on first run it even prompts you that it will change the screen unlock password.
2) Yes pressing the home button went to the Home screen (at this point if you switch the screen off then back on the Demo reruns).
3) Yes I did.
The code doesn't seem to work at the Emergency Call screen on my Xperia T, or perhaps the phone he's using in the Video doesn't have the most current firmware.

It is possible you can test the zip file method?

I'm on my way to work now, I'll try the 2nd thread a little later. I'll have to try Method B in that thread because I don't currenty have CWM recovery on my phone which is required for Method A using the Zip file.

ahh ok, neither does her phone so that wont work.... never mind thanks for your help

Had a thought what if I flash an older version of firmware which has the service menu security hole?
Would just have simply plug her phone in, flash it, and then let it restart (wiping only cache and dalvik, if they are available in stock recovery)
So she won't lose any of her data and won't be any wiser?
hmmm....

I've tested a similar method on windows that worked on my T on JB.
all it needed was a
adb shell
su

This of course has limitations, the device needs to be rooted and usb debugging must be enabled

Well I suspected that USB debugging would need to be enabled to use the B Method in that thread you linked and what Matt has said Tally's with this; I've now had time to try and can confirm this.
Matt's commands worked when I substituted 'password.key' instead of 'gesture.key' in the 3rd line (I had a PIN lock set) - 'gesture.key' seems to be for when a pattern lock is set, and 'password.key' for PIN lock.
Method B in that thread is missing the 'su' line that Matt has above, so failed with 'Permission Denied' when trying to delete the .key files - works once you add the su command.

Fix for no WiFi connection when Sim is active

I imported my HTC first from America and a major problem I found was that the WiFi didn't work. I was prepared to return my phone citing hardware problems but I waited and instead tried to find a solution by myself. I finally got it working.
This thread is for all others who have the same problem that I did.
Temporary Fix
1) unlock boot loader, root and do s-off
2) you must be running ruu 1.08.502.1
3) make your way to http://forum.xda-developers.com/showthread.php?t=1445766
There you can see many people have the similar problem.
Follow the instructions and install the app by the OP
(Make sure push the wifix app in the /system/app folder) verify the app is working properly by dialing the code given in the other thread. Open the wifix manager and set code to 'us'
4) if you read the thread you will see the app works for android 4.0 but most users having jellybean report it as not working
5) try the steps of post #250 (I used the AT&T code)
6) now whenever you restart make sure WiFi is switched OFF before reboot. When your phone boots up again make sure you're getting network signals, then open the market changer app and select AT&T. Then turn on the WiFi.
7) your Wi-Fi can see and connect to access points!
--------------------------------------------------------------------------------------------------------------------------
UPDATE 13/5/2014
WIFI NOW WORKS 100%
Ok with a lot of digging around I finally managed to fix my wifi. Sim inserted or not, wifi on/off at reboot or whatever, it doesn't matter because wifi always works. And no need for any annoying apps to run at boot!
For this method I had to endure a lot of headaches -_-
Had to search the whole internet, learn about adb commands, logcat, compiling .jar files etc
1) unlocked bootloader, rooted , s-off and running deodexed 1.08.502.4 . I did this on a clean install with no wifix/wifi codes/market unlocker
2)
First you have to learn how to compile and extract jar files:
http://forum.xda-developers.com/showthread.php?t=2251719
You just have to read "1. How to Decompile and Recompile *.jar file or classes.dex"
3) THIS STEP NO LONGER NEEDED *Removed*
4)
You need to read this too:
http://forum.xda-developers.com/showthread.php?t=2628707
modify "framework2.jar" which is present in /system/framework
And after you have decompiled, open on your PC
classout/com/android/internal/telephony/MccTable.smali
recompile framework2.jar , put it back in androids /system/framework and set permissions to Rw-r-r
Now we have to modify another file
This time its the /system/framework/framework.jar
after decompiling open in PC : classout/com/android/net/wifi/WifiStateMachine.smali
and edit as per the second post in the link, recompile and paste it back into system/framework,set permissions to Rw-r-r
Note : its best to use adb commands to copy and paste the framework files from android to PC and vice versa
(namely adb pull and adb push)
then do some extra steps:
"Extra step 1
click on "/system/build.prop" and open in any text editor(on android);
seek line
ro.product.locale.region=GB
and change GB to US; confirm OK for save file.
mount /system R
Extra step 2
because of first boots, in Settings database is written our country code,
which should be US.
for this: install "Sqlite Editor" (android app), run, grant ROOT access. after program finds
& lists databases, look for & open "Settings Storage" > settings.db > global:
find "wifi_country_code", select it and press menu button > Edit Record;
change value to US and press "save" "
Reboot.
Congrats!! Wifi now works no matter what you do!
(as long as your wifi is on channels 1-11 , if youre on channel 12 or 13 then I think you need to change wifi country code to an european country instead of 'us')
Note: Be sure to thank the original authors in the threads i've linked.
As usual, do these steps at your own risk, I am not responsible for your bricked devices. Do report if it worked for you.
Also I know i've made quite a bit of mess. Do tell if you have any problems with the steps. I was thinking about posting my own framework.jar and framework2.jar but i'm not sure if they are safe to share or they contain private data. I'll need to confirm from someone.

Gt-N7000 imei and power problem

Hello All,
I have Gt-N7000 note mobile. I am running JB germany official rom. Suddenly my phone has restore it default imei "0049999010640000" so i can register on any network. Also, the power button problem appeared to me. When i press it for a long press the menu of restart does not pop up instead the phone just power off and if i pressed for a short one, the phone will just turn off the screen so if press it again or the home button, the phone would just open and bypass the lock screen.
Thanks for ur help guys

Try to explain this again.
Can you register on a network?
Or can't?
This IMEI is not a "restored" one. You simply lost your original one. If you did not make and do not have a backup of your /efs then it's lost.
So: was your device rooted? What did you do before "suddenly"?

i really mean suddenly. The phone was OK then it lost its imei. I can not register to my network anymore. the mobile internet is working fine but i can not make any voice calls. The phone was not rooted then but i root it now.
For the EFS folder, i do not have a backup

Workaround 1: disable SIM pin number. After that the network should work
Workaround 2: use an older version of android.policy.jar (from an unofficial developer release from Samsung). In this versions the check for a corrct IMEI seems to be disabled.
I have this problem myself and was lucky to get an upgrade with the so called developer imei. Since then I use the android.policy.jar from this upgrade.
But please try W1 first. If you'll get the network then it is solvable with W2.
If W1 doesn't work then even W2 will fail.

Of course you should try it.
First root your device. Go to Philz kernel thread and download the kernel for your JB version (XXLT4?).
Tomorrow I will connect to my PC in Germany and download the old version from there (right now I'm in Thailand).
Will attach it here.
With a rooted device and a file explorer with root options you can copy it to your device.

Great..thanks alot.
And for the power problems? do u have any opinion?

sorry but it worked on an operator and did not on another. i could not register on my main network using the W1 solution.

Yes, same reason. When I use the other jar this problem disappears too.
I just copied the file from my N7000 and attached it here.
Copy it to /system/framework. Change permissions to rw-r-r.
For this you need a rooted device and something like Total Commander with /system mounted as writeable. And before you do this make a backup of you android.policy.jar.
If you do not understand these things right now: start searching and reading here about root explorer, mounting /system, permissions. There are enough examples and descriptions.
But first: root

If it's the U1 3AUDD update you can't downgrade. The bootloader revision has been bumped to 3 and there is no going back to bl 2.

I'm pretty sure you can't downgrade because the bootloader is a different version than the previous version. The number that is shown 5 characters from the right on your Build Number identifies the bootloader version. The May update took me to bootloader version 3. Prior to the upgrade, I was on bootloader version 2. Forgive me if I'm wrong, but I don't believe you can downgrade once you've updated to a different bootloader.

May update clearly mentioned in it's changelog that it was not possible to go back to older firmware after updating. No dice.

You could try PDANet

Are you in the US?
I haven't tried to tether with this phone.
So, you're saying that if I tether, it will check with T-Mo or whatever my carrier is to see what I'm eligible for?
I guess that was 1 benefit about the Pixels. No checking, just tethering!

Very happy with May update

OMG THANK YOU I LOVE YOU! IT DIDNT CARRIER CHECK 👁👁 but I'm not updating to any future updates at this point unless someone else can confirm it turns on still

Here's a work around I found:
Download Activity Launcher from the play store -> go to the search on the top right -> type in "tether" -> it should search for "Mobile Hotspot and Tethering (there should be 3 that pop up) -> choose the 2nd one -> click on "WiFi Hotspot" -> click On.
I don't take credit for this as I found this on reddit. It worked for me and a few others. Good luck!

Thank You soldier.
By the way, folks: you can make this work with Shortcut Maker too. Great app.
Thank You to Samsung for leaving this untouched, LOL.

Other than locking you in so you can't go to an earlier version does it serve any useful function?
