For Singapore user. Root + flash jme v.4 + data 3G

Hi,
Finally got my galaxy tab to work after 6 hours. Now it is running well.
As it is 4 am here, i will post a guide for Singapore users once i wake up as i have meet with problems during the whole process.
Luckily, all information can be found on this forum but just that you will have to read through 20 plus pages from different topic in order to get the answer.
Super happy with my phone now!
*just another newbie* =)
Sent from my GT-P1000 using XDA App

Sorry to steal your thread. Singaporean tab user here as well. I think we should constantly update this thread for singapore users. I was running dxjm4 up til this morning when i decided to flash to roto-jme. spent the last few days reading the thread and considering whether to upgrade or not because of the lack of information for singapore users. so i decided to take the plunge and just go for the upgrade no risk no gain. my tab got stucked at the samsung logo after it auto rebooted but it was fine after i manually rebooted it
what i did was to upgrade from jm4 instead full flashing my tab. it turned out fine so far but there's one thing that puzzles me. the apps that roto mentioned were removed are still in my tab such as daily briefing etc.. do u have this problem as well?

Not Too Sure... I am new to Galaxy Tab or rather Android =P
But i suggest you do a full flash again.
i wasn't ready to even root my device initially as i only gotten my Tab on Saturday 7th Jan 2011.
One thing that actually forced me to root and flash the rom is the stock version whether bug or not i just couldn't sync with my company exchange 2010, which is critical for me.
Nonetheless, i haven't tried the jme v4 as yet (I suppose) as i did not know how to get it to work.
All i did was follow:
http://forum.xda-developers.com/showthread.php?t=895827
And all went well, except that Data doesn't work.
Thoughout the whole process i did not use the file name "Roto-JME-Full-v4"
which set me thinking whether did i actually do the right thing.
One thing is most of the stock app was gone, baseband was change to I9000UGJK3, Kernel Version 2.6.32.9 [email protected] #1 and Build number is Froyo.XXJME.

i am new to android too and this is my first android device. your baseband is weird? I9000? which firmware did u flash???

Root devices *Important Points
And Yes i woke up...
Anyway i do not gain credit from the guide itself as everything can be found in this forum. If you want to thank people, please thank the people that writes the program and the trial & error people if you find my thread useful. I am just consolidating all the steps that i used to flash my Tab, important things to take note of and etc...
Step by step guide to Rooting:
Please read
http://forum.xda-developers.com/showthread.php?t=812367
*Important points to Note when Rooting"
Process:
1) Connect your galaxy tab with debugging mode disabled and sync with Kies even once - You must be damn sure Kies can connect to your phone
2) Disconnect it and enable debugging mode from Settings>Applications>Development>USB Debugging
3) Connect the tab again to PC and click on home button so that Tab comes out of Kies connection - I found that after USB Debugging is turn off, Kies can still find your phone but it will just appear as Connecting... on the top left hand side of Kies. (I left my Kies on throughout the process)
4) Launch SuperOneClick.exe
5) Click on root and wait for 5-10 Mins - it stated 5 - 10 min but it took like 5 - 10 sec for SuperOneClick to prompt me saying that device is rooted.
And that all for Rooting whole process took me about 5 min Including all the reading. (Simple Great Job by SuperOneClick!)
Now comes the slightly complicated part: Flashing New Roms
Below is the thread that is used
1) http://forum.xda-developers.com/showthread.php?t=894763
2) http://forum.xda-developers.com/showthread.php?t=895827
What i did was:
1) Download OdinV3 1.7 (Provided in the thread 895827)
2) Download Addon-JME-Modem.zip (http://files.deodexed.com/ModADroid-Galaxy-Tablet/Rotohammer/JME/)
3) Download P1_add_hidden.pit (http://files.deodexed.com/ModADroid-Galaxy-Tablet/Rotohammer/JME/)
4) Download Roto-JME-FmtIntSD.zip (http://files.deodexed.com/ModADroid-Galaxy-Tablet/Rotohammer/JME/archive/)
Additional:
I also downloaded (But till now i have not use any of the file below)
1) Roto-JME-FmtIntSD-v2.zip ( http://files.deodexed.com/ModADroid-Galaxy-Tablet/Rotohammer/JME/archive/)
2) Roto-JME-Upgrade-v4.zip ( http://files.deodexed.com/ModADroid-Galaxy-Tablet/Rotohammer/JME/)
Why is it not used, i myself is not too sure. For FmtIntSD alot of people is asking which is it to use as there are 2 different version 1 & 2 (i Suppose).
I have used the Version 1, as the time posted in the FTP link seem to be later than Version 2.
Also as thread http://forum.xda-developers.com/showthread.php?t=895827 shows in the screenshot, under tab CSC: Addon-JME-Hidden.Tar, this file is missing plus confirmation from the thread saying that it will fine without it.
Once downloaded, it is time to get to business =)
Steps i took:
1) Startup Odin
2) Connect Galaxy Tab to Kies make sure Kies is able to connect to the device and is able to Sync with device (Toggle with the USB Debugging option Either On or OFF) *My kies is never turn off from the start Rooting to Flashing* i think in order for Odin to work properly, Kies must be able to detect the device is been plugged in. (Just my Thought)
3) At this point of time Odin will also detect the device been plugged in as show in the screenshot provided in thread 895827. The yellow box will appear stating COM10 or 11 or 12 (DOesn't matter what com Number)..... Left hand bottom of ordin will also show Added!
Checked Make sure and double checked.... Yeah the next part!!!
4) Unplugged my phone from the USB
5) Off my phone
5) On my phone to get to the downloading mode (Hold Power Button and Volume Down Button)
6) Checked my Odin, Bottom left log shows REMOVED!
Hell Ya exactly the same as the sceenshot.....
7) Plugged in my phone with the Downloading screen....
8) Waited.... Waited..... 5 min pass..... Windows 7 is still searching for "Gadget Serial Port" Odin didn't detect the device connected.... don't have to worry Windows 7 will eventually find the driver, just got to give it sometime (Just in case you meet with the same problem like i did, Windows 7 took almost 10 min for the device to be ready)
9) Check Odin, Bottom left hand log.... ADDED!
Almost there.....
10) Plant in all the .Tar file as show in screenshot (Thread 895827)
*Please make sure you unzip the .rar file the logo is similar to winrar icon once you unzip. Can get a little messy, what i did was unzip and delete the original zip file that i downloaded. Remember JME-Hidden.Tar is not needed, just leave it blank*
11) Tick the "Re-partition" in Odin
Now you are all ready to start, double check all the setting and click the "Start" in Odin... =)
12) Pray.... Pray... Pray....
Whole process took me about 5 min, Odin will show you the details as it is flashing, Installing and Bla Bla Bla.... Once it is ready, Odin will prompt you either Successful or Failed...
Phone will automatically restart. Just leave it till you see the main screen comes out.
* I Succeed on my first try, so if you fail i guess you got more reading to do than me, but i am sorry that i am unable to help if you fail at this point*
Now then all good, checked my phone all seem well... did a call to my house number, Working....
Now the complication that i faced: My 3G (data Services) is NOT RUNNING!!!!
Did a search on the forum and found a few threads that is helpful:
1) http://forum.xda-developers.com/showthread.php?t=901021
2) http://forum.xda-developers.com/showthread.php?t=845263&highlight=modem.bin&page=3
3) http://forum.xda-developers.com/showthread.php?t=847273&highlight=modem_bell_i9000
* I Have attached the modem.bin that i use to get my 3G working, but before you download the attachment please do a few check as stated below.Things to check if your 3G (Data Service) is not working:
1) APNs setting
Setting>Wireless and Network>Mobile Networks>Access Point Names
2) Select the Access Point Names and see if there is any setting inside.
3) If it shows "No Setting"
4) Tab on the bottom left hand corner of your galaxy tab, "MENU" button beside the "Home" buttom
5) select "Add APN"
6) Use the information below, key in whatever is there. Those that you don't know just leave it blank. (As long as your are in Singapore i believe you know which telco you are with)
StarHub (Singapore)
APN: shwap or shwapint
Leave user/pass blank.
M1 (Singapore)
APN: sunsurf
user: 65 pass:
user123
swirlyMMS :
MMSC and Proxy server settings MMSC : http://mmsgw:8002/
Proxy : 172.16.14.10:8080
MMS-specific APN Settings
APN: miworld
username:65
password:user123
SingTel (Singapore)
APN: internet
Username: 65IDEAS (or blank)
Password: IDEAS (or blank)
Once Key-in "MENU" button again and safe the setting, now go back to your APNs and check to see if you have selected the setting you key-in (Button on the right hand side will be "GREEN"
Now Wait & Pray that the logo "3G" or "H" appear on the top beside your signal strenght bar.
if no launch your dialer (Press Phone) and Dial *#2263# select "automatic" 1st option. (Select it once and exit by pressing "HOME" or "BACK")
Wait & Pray....
I believe this should get it going as under JME-Modem.zip, the modem should already be in.
__________________ I sincerely hope that you do not have to do the step below________________________________________________
If the 3G or H is still not showing after you tried the above step. Download the modem.bin (Attachment in this thread modem_bell_i9000.zip)
Then follow the step below:
1) Unzip the file
2) startup Odin
3) Browse for the Modem.bin, using Odin "Phone" Tab (File you unzip from the attachment downloaded from here)
4) off your phone and boot it up to the "DOWNLOADING SCREEN"
Checklist:
5) Re-partition is NOT tick
6) Odin detect your device
Hit "Start" and wait for your phone to reboot.
*I succeed with this flashing of modem, if you fail all i can say is good luck*
Once your phone is up, check on the APNs setting again (Key-in the details is there is nothing in the list) Check on *#2263# and set it as automatic.
Then End.....
Conclusion:
I use the exact same step for my phone, and get it going. I hope it helps you.
Again i would want to highlight that none of the above is by me, all information can be found in thread posted by other users. Please give thanks to them as they are the one doing the job, taking risk to try ROMs, Root and etc...
=) i hope my thread helps anyone with the same problem as me...
PS: DO NOT HOLD ME RESPONSIBLE IF THE ABOVE GUIDE DOESN"T WORK FOR YOU.

Hi Kay Kiat,
I Seriously don't know. See the steps i posted, i believe it is because i flash a i9000 modem in that is why my baseband is weird. =p
i believe all i need to do is to re-flash the Jme modem in, and it should be right.
But currently at work no time to try. haha
Best Regards

Hi guys, Singapore GT user here also. Looking forward to try out your guide.
EDIT: Just flashed Roto's JME-Full-v4 with repartition. All works fine. No modem flash required.

are you talking about the keyboard?

Hi,
wanted to share my experience from flashing this Rom.
The way I've done it is download the latest full version find in the ftp site (not the archive) directory and using Odin to fladh my tab. I also downloaded all the other files but did not use them.
Overall, this rom is good. It solved my exchange problem but i've lost a few things as well. There's no more chinese input and i'm no longer able to zoom and pinch on dolphin browser. Does anubody has any solutions to these problems?
Thx.

This was solved in another thread, maybe the Roto-JME one itself. Theres a new version from Dolphin with the fix. You'll find it

The Roto-JME-Full-v4 will format the internal sdcard only if it is corrupted. So you can shorten the steps to just flashing that one firmware. The ones in the archive are there just in case we needed to test something.

APN settings
Hi
Did you guys copy down the APN settings and did you manage to get your MMS working? I only have my 3G working. Was trying out the different settings to get MMS working too.
ps: for chinese input, can just install google pinyin. been using it since Im only android. swype does have chinese input but the one on the tab doesnt have it. I was testing the beta using my hero and i can do chinese input using the swype keyboard. i wonder if there is anyway to update the swype version to the latest one released by them.

You'll need to goto Setting-Locale and text, check the Penpower Input Method. After that, at any input screen, press & hold - then select the input method.

A powerful bomb problem

I have a Galaxy Tab S4 device
I installed the following file on it
COMBINATION_FAC_FA81_T835XXU2ARI2_FACFAC_CL14168542_QB19864423_REV00_user_mid_noship_MULTI_CERT.tar.md5
Now the device has reached an interesting and strange situation that I do not know
I want to go back to the previous situation.
I can not get back to download mode.
I want to install back the real firmware.
How do I get out of this situation or I can switch back to download mode.

Connect your device to a PC.
Then using adb type the following into a command prompt:
adb reboot download

Then I tried to re-install, and installed something wrong, and it wrote me this:
SCURIYY EROR: THIS DEVICE HAS DEEN FLASHED WITH HNANAHORIZED SOFTWARE & IS LOCKED. CALL YUR MOBILE OPERATOR FPR ADDITIONAL SUPPORT. PLEASE NOTE THAT REPAIR / RETURN FOR THIS ISSUE MAY HAVE ADDITIONAL COST.
I gave it to the repair shop, I hope they will succeed and that it's cheap ...

Thanks for that tip, Ashyx. That saved my day. BTW, what is that password that the Factory Binary SW asks for? What's the reason for a password there?
I was trying this "Factory Binary" (combination) firmware because as soon as Pie came out for my SM-T835 (Galaxy Tab S4), it was available only for France (CSC = XEF) and I wanted to preview Pie/One UI in my device. Then my region's firmware (Brazil Open, CSC= ZTO) came out and I flashed it on the tablet. For some reason, my CSC became CHO (Chile Open), and I wasn't able to revert it back to ZTO (although it's a Multi-CSC and contain both regions) . Then I flashed
COMBINATION_FAC_FA81_T835XXU2ARI2_FACFAC_CL14168542_QB19864423_REV00_user_mid_noship_MULTI_CERT.tar.md5
(AP only) after having flashed official
T835UBU2ARL1_CL14803871_QB20870118_REV00_user_low_ship_MULTI_CERT_meta.tar.md5
but after entering code *#243203855#, as described in
https://www.sammobile.com/forum/threads/39155-How-to-change-CSC-with-a-combination-file
the code was recognized (cleared from the dialer) but no CSC selection appeared.
Do you have an idea where it went wrong?
Thanks in advance.

VOLTE Success, Activation without Firmware Replacement (Sony Mobile withdrawal area)

Hello Xperia users! In the meantime, I finally solved the VOLTE problem! I approached Qualcomm's diagnostic port-active-efsExplorer and solved the problem by inserting a VOLTE profile from my carrier
Sorry, this is Korea and I am Korean.
However, I will write down the method in English.
Unlike previous 1&5, Qualcomm's diagnostic port cannot be opened.
opening command
I don't even know. I don't think so.
So it's a little different from before.
I tried to force it open.
debugging connection
Open the Command Proposal window.
adb shell input
su input
Do you want to allow shell on your phone?
prompt acceptance of permission
Then the $ shape changes to #.
Now
setprop persist.usb.eng 1
Copy paste entry. Please enter
And you're gonna be out there during tethering.
In My Computer Item
View Device Manager.
Please turn debugging back on.
Of course, no access.
If you turn on debugging again,
I've already set it up, so it looks like that.
Among them, there is a product model named XQ-AT52.
There are four yellow exclamation points in total.
Manually update driver Press [port] to list the manufacturers
It's called Qualcomm hs-usb-diagh and 9091. with this
I need a manual update. gogo
Now run the EFS Express.
Press 0 on the ROW and OK.
(ROW or SF_Default)
Oh, it takes a long time. I thought it stopped.
It opens if you stay still. LOL
It's open. How nice to see you here!
I am the Korean telecommunication company EFS file extracted from xperia1.
I used it. If you need VOLTE,
XPERIA1 (Modem).Extract from SIN file
I will use the Korean communication file.
Just drag it and put it in a folder.
v check and Yes
There'll be folders that don't exist while you're pulling them in.
Then make it and put the file in.
In the folder where you can view this red file,
Drag and drop the file twice.
The reason is that once you do it, you just go in.
The red file is not updated.
That's how the numbers at the back change when you renew.
So make sure to put it in twice.
Files beginning with NV do not have folders.
Put it on top.
It's over now!

It was terrible to be on the 3G phone.
If there's someone like me,
This information will help you a lot.

It's hidden in XPERIA1 firmware.
After downloading the firmware via Xperia Pim, change the extension to Modem.img in the Modem.sin file and extract it to the compression program (7z) to view the folder! Surprisingly, the world's telecommunications company VOLTE EFS file is hidden. +_+ Take advantage of it! You can open the VOLTE menu through the magazine module.

Hi, why don't you show by video or pictures. The windowns language is English. ???
Attach the necessary software.
Thanks

I estimate, its only possible by unlocking/rooting the phone?

how to
Even with the great contributors' information, I think there are a few areas where I struggle.
For additional information, I will post my success stories.
I'm posting them in machine translation. Please forgive me if it's hard to read.
STEP 1: Implement the Tools You Need
Please install the following tools.
QPST(QPST_2.7.460)
Qualcomm-hs-usb-diagnostics-9091-952454(DIAG driver)
Flashtool (and XperiaFirm)
newflasher(INSTALL is unnecessary, but please get it.)
*All of the above were available on the internet as of 8/15.
STEP2: Get a "modem" that supports VoLTE.
　As a prerequisite (regardless of the DualSim/SinglSim model)
　　For countries that want to use VoLTE, SONY is offering
　　Official firmware is required.
　　In my example.
　　Purchased model: XQ-AT52 (for Hong Kong)
　　The country where you want to use it: Japan -> SO-51A is available.
　　(The difference in the number of slots in the SIM doesn't affect it. )
　　This is the case.
　　If the firmware to run VoLTE does not exist in the country where you want to use it
　　This method does not work.
　　The annotations are long, but here are the steps.
　　Use XperiFirm, provided by SONY in the country where you want to use VoLTE.
　　　Download the firmware.
　　
STEP3: Use the newflasher to write the firmware from STEP2 to your Xperia 1 ii.
　　　In this case, if you want to burn into a model with a different number of SIM slots
　　　Example: Writing SO-51A firmware to XQ-AT52
　　　→The SIM will not be recognized, but it is temporary.
STEP4: Use EFS Explorer to get the necessary files.
　　Follow the steps of the great htcmage and have your Xperia 1 ii recognized by EFS Explorer.
　　4-1: Install the QPST.
4-2:Install Magisk on your Xperia 1 ii.
　　　　Therefore, it is mandatory to unlock the bootloader.
　　4-3:Execute the commands at the command prompt as follows.
　　　　adb shell
su
setprop persist.usb.eng 1
Magisk's permission is now required to get SuperUser privileges in su.
　　　　　Note: From the Magisk menu, go to "# SuperUser" and click on
　　　　　You can allow.
4-4: The debug mode is disconnected, so you need to re-enable it.
4-5: If you have installed the qualcomm-hs-usb-diagnostics-9091-952454 (DIAG driver), you can use
　　　　It is recognized by EFS Explorer.
4-6: On the Phone Selectio screen, Banner selects the ROW port.
STEP 5: Back up the files required for VoLTE activation.
Before following the steps below, you must have the SIM of the line/carrier you want to enable VoLTE on.
　　　　Please plug in.
　　　I have backed up the following folders.
　　　There may be some things you don't need, but at least it works.
　　　Data_Profiles
efsprofiles
Ims.
nv/item_files/datamodem
nv/item_files/ims
nv/item_files/mcfg
nv/item_files/modem
STEP6: Write the firmware you want to use, and copy the file from STEP5 to
　　　Override.
Follow steps 3 to 4 of STEP 3 to 4 to get the firmware you want to use.
　　　Write & make EFS Explorer recognize it. (Don't remove the SIM.)
　　　Then, overwrite it with the files backed up in STEP 5.
You should probably now have VoLTE available.
Thanks to the person who walked me through the Magisk installation process, and to the great htcmage.
Also, I pray that others wandering in the same sea of information will be saved.

Magisk's permission is now required to get SuperUser privileges in su.
　　　　　Note: From the Magisk menu, go to "# SuperUser" and click on
　　　　　You can allow.
4-4: The debug mode is disconnected, so you need to re-enable it.

　　　　It is recognized by EFS Explorer.
4-6: On the Phone Selectio screen, Banner selects the ROW port.
STEP 5: Back up the files required for VoLTE activation.
Before following the steps below, you must have the SIM of the line/carrier you want to enable VoLTE on.
　　　　Please plug in.
　　　I have backed up the following folders.
　　　There may be some things you don't need, but at least it works.
　　　Data_Profiles
efsprofiles
Ims.
nv/item_files/datamodem
nv/item_files/ims
nv/item_files/mcfg
nv/item_files/modem
STEP6: Write the firmware you want to use, and copy the file from STEP5 to
　　　Override.
Follow steps 3 to 4 of STEP 3 to 4 to get the firmware you want to use.
　　　Write & make EFS Explorer recognize it. (Don't remove the SIM.)
　　　Then, overwrite it with the files backed up in STEP 5.
You should probably now have VoLTE available.
Thanks to the person who walked me through the Magisk installation process, and to the great htcmage.
Also, I pray that others wandering in the same sea of information will be saved.

Hello, you are so cool Thank you so much for organizing the guide. I hope it helps many xperia 1 II users ah! I opened the volte-related menu without changing the firmware using the magical module. The reason is that the buildprop cannot be modified for this xperia1 II
pa// Attached file for used module

Has anyone had success doing this on the Xperia 5 ii ?

Hello Xperia users! In the meantime, I finally solved the VOLTE problem! I approached Qualcomm's diagnostic port-active-efsExplorer and solved the problem by inserting a VOLTE profile from my carrier
Sorry, this is Korea and I am Korean.
However, I will write down the method in English.
Unlike previous 1&5, Qualcomm's diagnostic port cannot be opened.
opening command
I don't even know. I don't think so.
So it's a little different from before.
I tried to force it open.
debugging connection
Open the Command Proposal window.
adb shell input
su input
Do you want to allow shell on your phone?
prompt acceptance of permission
Then the $ shape changes to #.
Now
setprop persist.usb.eng 1
Copy paste entry. Please enter
And you're gonna be out there during tethering.
In My Computer Item
View Device Manager.
Please turn debugging back on.
Of course, no access.
If you turn on debugging again,
I've already set it up, so it looks like that.
Among them, there is a product model named XQ-AT52.
There are four yellow exclamation points in total.
Manually update driver Press [port] to list the manufacturers
It's called Qualcomm hs-usb-diagh and 9091. with this
I need a manual update. gogo
Now run the EFS Express.
Press 0 on the ROW and OK.
(ROW or SF_Default)
Oh, it takes a long time. I thought it stopped.
It opens if you stay still. LOL
It's open. How nice to see you here!
I am the Korean telecommunication company EFS file extracted from xperia1.
I used it. If you need VOLTE,
XPERIA1 (Modem).Extract from SIN file
I will use the Korean communication file.
Just drag it and put it in a folder.
v check and Yes
There'll be folders that don't exist while you're pulling them in.
Then make it and put the file in.
In the folder where you can view this red file,
Drag and drop the file twice.
The reason is that once you do it, you just go in.
The red file is not updated.
That's how the numbers at the back change when you renew.
So make sure to put it in twice.
Files beginning with NV do not have folders.
Put it on top.
It's over now!
Volte Success ^0^ About IMS
VOLTE OK

It was such a hard time for me!
I was sad because I couldn't get help.
With 5G mobile phones in 2020,
It was terrible to be on the 3G phone.
If there's someone like me,
This information will help you a lot.

Do you loose 5g support after this method?
Does your mobile restart after changing the data carrier from Sim1 to Sim2?

Hi! We have the same model, where did you sim unlocked your device?

sura_tth said:
how to
Even with the great contributors' information, I think there are a few areas where I struggle.
For additional information, I will post my success stories.
I'm posting them in machine translation. Please forgive me if it's hard to read.
STEP 1: Implement the Tools You Need
Please install the following tools.
QPST(QPST_2.7.460)
Qualcomm-hs-usb-diagnostics-9091-952454(DIAG driver)
Flashtool (and XperiaFirm)
newflasher(INSTALL is unnecessary, but please get it.)
*All of the above were available on the internet as of 8/15.
STEP2: Get a "modem" that supports VoLTE.
　As a prerequisite (regardless of the DualSim/SinglSim model)
　　For countries that want to use VoLTE, SONY is offering
　　Official firmware is required.
　　In my example.
　　Purchased model: XQ-AT52 (for Hong Kong)
　　The country where you want to use it: Japan -> SO-51A is available.
　　(The difference in the number of slots in the SIM doesn't affect it. )
　　This is the case.
　　If the firmware to run VoLTE does not exist in the country where you want to use it
　　This method does not work.
　　The annotations are long, but here are the steps.
　　Use XperiFirm, provided by SONY in the country where you want to use VoLTE.
　　　Download the firmware.
　　
STEP3: Use the newflasher to write the firmware from STEP2 to your Xperia 1 ii.
　　　In this case, if you want to burn into a model with a different number of SIM slots
　　　Example: Writing SO-51A firmware to XQ-AT52
　　　→The SIM will not be recognized, but it is temporary.
STEP4: Use EFS Explorer to get the necessary files.
　　Follow the steps of the great htcmage and have your Xperia 1 ii recognized by EFS Explorer.
　　4-1: Install the QPST.
4-2:Install Magisk on your Xperia 1 ii.
　　　　Therefore, it is mandatory to unlock the bootloader.
　　4-3:Execute the commands at the command prompt as follows.
　　　　adb shell
su
setprop persist.usb.eng 1
Magisk's permission is now required to get SuperUser privileges in su.
　　　　　Note: From the Magisk menu, go to "# SuperUser" and click on
　　　　　You can allow.
4-4: The debug mode is disconnected, so you need to re-enable it.

Hi!
I think i missed something during yoyr great guide . My case is that I'm in Israel, where Sony doesn't provide original firmware, and I use Xperia 5 iii (XQ-BQ52 from UK), So will this guide work?
Thank you

I used a software called S1 Unlock Tool. You need to buy a credit from this website: https://networkunlocking.com/shop/sony-xperia-cable-unlock-0-counter-supported/. There is also a link to download the software. Along with unlocking your phone it will also grant you access to unlock your bootloader if you wish to do so. I did this and tried to root my phone but I wasn't successful, it just soft bricked my phone and was stuck in a boot loop. I had to use Xperia Companion to restore my phone. Maybe you can't root the Japanese variants, I'm not sure. I saw on here on another forum that you can root the Xperia 1 II.

[Guide] How to change CSC on A71

Disclaimer: This post is an adaptation of the original one in A51 forum. Thanks!
Warning: Do this at your own risk, I am not responsible for any damage that is caused to your device. This method worked for me and should work for everyone.
Credit to yakapa40 on XDA for the apk. This would be impossible without him!
You must make sure the model numbers are the same for the country you want to change to. To check that go to
https://www.sammobile.com/firmwares/recent/
and type in your device model number. Leave country code blank. The countries that are listed are those that will work on your specific device. DO NOT TRY TO CHANGE TO A DIFFERENT MODEL NUMBER COUNTRY!
MAKE sure device has above 70% battery just to be safe
OK lets start!
Backup all your data on samsung cloud and google
This process will erase all your data
Download samsung drivers
https://www.hardreset.info/download/samsung-drivers/
Check the CSC code you want from
https://forum.xda-developers.com/sho....php?t=2546689 credit to Jasi2169
Important later
Download the firmware you want from sammobile (slow download speed) or
https://samfw.com/ for faster download speeds.
It will be a zip file so use winrar to extract and you should get 5 files that start with
AP (System &Recovery)
BL (Bootloader)
CP (Modem / Radio)
CSC\_ (Country / Region / Operator)
HOME\_CSC (Country / Region / Operator)
DELETE the home file.
Next download Odin.
https://dl2018.sammobile.com/Odin3-v3.14.4.zip
Extract the Odin file and run as administrator.
Add each file to its respective field in Odin.
Now we need to put the phone in download mode to do that go to:
https://www.hardreset.info/devices/s...download-mode/
Keep trying until it works.
Next plug the device in and press start. It should take about 3-4 mins for odin to say PASS.
DO NOT UNPLUG THE PHONE AT ANY POINT EVEN AFTER ODIN SAYS PASS.
Let the phone do its thing and dont worry if it takes too long on the Samsung screen.
You should then be greeted with the welcome screen BUT it may not be the correct language so set it to English.
Set the phone up but dont worry about apps we are going to reset the phone again.
Head over to (APK provided by yakapa40).
https://drive.google.com/file/d/1hU3...ew?usp=sharing.
on your device or PC and download it. Extract and it should be a apk file. Download it with your device.
Allow unknown sources and it should says done and not open (that is normal).
put you device in flight mode/airplane mode.
hold down the home screen and go to themes.
Galaxy themes.
My stuff.
Select mysterious theme(make sure not to click update).
Select try it out.
Go to Settings.
About phone.
Legal information.
Change Carrier or whatever third option is (the one that says android 10).
Choose and install the CSC you want (that 3 letter code) remove sim and it will restart phone.
again, dont worry if its on the Samsung screen for too long.
You should be back on the welcome screen and you are done!!!
Set up the phone and enjoy!!!
Credit to yakapa40 again on XDA for the apk. This would be impossible without him!

Download link is broken

This app will NOT work on firmware with August 2020 (or later) security patch. .
The App was originally discussed in the S20 thread and stopped working for all Samsung models if August update was installed)

is there any easier way for changing CSC?
this one seems so complicated.

Stock Firmware for Active Watch 2 LTE - Tizen 5.5.01 - Germany - Help needed "please"

Hi Guys,
i want to install the stock firmware from samsung on my active watch 2 LTE, but I cannot find the right Files online.
Can you support me with the right files?
Why...
I tried to flash via Net_Odin to change CSC (to make BP, ECG and so available on my German Watch).
I dont know why, but it failed all the time by using following file:
-COMBINATION-FT40_R825USQU1ASL2.tar
Now I heard that BP and ECG will be available soon in Germany, so a flash to a custom firmware is not needed anymore.
Now the Watch always goe into Boot Mode and thats it.
I can go to the screen were I can acitivate AP mode and WIFI is working fine to connect the watch with my PC and use Net_odin again.
Can you help me, to get my Watch into "standard" Setup again?
Thanks a lot

I´ve read other THread regarding "flashing the active 2 watch".
For now i would do following steps...
1. Change Watch into AP Mode and connect my pc to it.
2. Open netodin and flash 4 files
-AP_R825FXXU1BTI9_usr.tar.md5
-BL_R825FXXU1BTI9_usr.tar.md5
-CP_R825FXXU1BTI9_CL1701429_QB16973615_SIGNED.tar.md5
-CSC_OXA_R825FOXA1BTI9_usr.tar.md5
3. Reboot the watch
4. use to files to activate ECG and BP
-SHM1.1.0.175.mod4.apk
-TPKpusher_v9_BPandECG_31_inside-apk
Am I right?
Thanks a lot.
