Sim Unlock in Singapore

Hi All,

Anybody kind enough to be able to guide me to somebody in Singapore who will be able to sim unlock M8 Harman Kardon for a fee? I'm not tech inclined so doing this myself is impossible.

Kindly reply this message or PM me. Many thanks in advance!

read the few posts above (post 110) on how to enable 2100 MHz band using QPST to enable 3G/H

E/a/G3cDK"]



I have unlocked ONE M8 here in Croatia on GSM network. I am also getting only 2G.

Are there any risks when trying to enable 3G via this method?

Also the HTC updates I downloaded don't seem to work in regards with mobile data, I always get an error message (works only with CDMA network).

I currently live in the US. Assuming I get a Sprint M8 but with a bad ESN, will I be able to use this method to unlock it and use with AT&T or any GSM carriers worldwide ? I don't plan on using Sprint network ever.

NO S-OFF Needed for M8 Sprint SIM Unlock

I just want to share with you guys my experience....

I was able to get my hands on one of these Sprint M8 and like everyone else, I wanted my phone to be SIM unlocked (to use it outside the USA). So, I followed instructions provided in the OP but at the S-OFF part I got stuck, since the Firewater method does not work in my phone.

Unable to get S-OFF, I skipped that part only to find out that when you replace the /system/app apk file, when you restart the phone, the changes are not saved, so the SIM Unlock Helper thing does not work. So, I was thinking, why would an app need S-OFF, I thought maybe the original HTC software was somehow preventing a system app to be replaced.

To make story short, I installed Viper ROM, and with root explorer I was able to overwrite the HTCOM... apk (change the .apk permision to allow everything), did a hot reboot, then a full reboot, and the unlock app worked perfectly, tho it crashed in the first attempt but I tried again and it worked!

My conclusion, you need to S-OFF in order to unlock this phone only if you are willing to install another ROM.

Anyway, if you guys need any details, I'll be glad to help you.

Thanks to the OP!

Hey Thanks. I have couple of M8 waiting for unlocking. My bad that on both the devices, Firewater does not work. You post did give me a hope that if I install custom ROM, there is no need to S-off.

So, if I install http://xdaforums.com/showthread.php?t=2729170, will that help?
Also, what permission is required to be modified? rw-r-r?

Please help.

Yes, it doesn't work on the newer updates (kernel made after June) and even if it did, it would require a reboot for the other stuff and it'd all be disabled due to the system r/w protection.

4.4.3?

I have a completely stock Sprint HTC M8 with 4.4.3. I just have a few questions before i attempt the unlock to use the device outside of the US with an international carrier.
  • Would the method described work with this version of android?
  • If the method is unsuccessful, can i revert the phone to completely stock? i.e. relock bootloader, remove custom recovery and remove root?
  • If the method works, can I remove root and remove custom recovery and the phone still be sim-unlocked? I want to be able to receive official OTA HTC updates.

    100% Work For Gsm Unlock Stock 4.4.2 ( Permanent )

    Step 1 - Unlockbootloader-custom recovery-root-s.off
    - Unlock bootloader from htc dev
    - donwload and Install Custom Recovery TWRP link http://xdaforums.com/showthread.php?t=2698400
    - download and install SuperSu from TWRP link http://xdaforums.com/showthread.php?t=2698400
    - S-Off Using firewater and follow Instructions (normal, rooted device method) link http://firewater-soff.com/instructions/ or Using Sunshine (25$)


    Step 2 -
    Download HTCOMADM_SPCS.apk and put in internal storage phone
    Download and install root explorer
    Download and install htc one sim unlockhelper from playstore

    Step 3 -
    Open root explorer and hit button Mount r/w for permission read.write
    Backup original HTCOMADM_SPCS.apk and HTCOMADM_SPCS.odex by changing the file name ( anything that is easy to remember ) From /system/app directory
    After rename the original file, copy modded file HTCOMADM_SPCS.apk to /system/app directory and make sure you have set the permission rw-r-r and reboot device

    Step 4 - Begin Sim Unlock
    Open htc one sim unlock helper on your phone, it will say htc one device check fail. now click the 3 menu dot and click on "Display SIM Unlock Log" It might ask you for Permissions. Make sure to Grant them. After that it will say "SIM Unlock Log". There shouldn't be anything there. Now hit the back button and now it should say Device Verified, Root Available etc.
    Next hit "start" button. If everything goes well, within seconds you should be in the OMADM Test Client Menu and Scroll all the way down to the end and tap the selection SIMLOCK. The phone will freeze a couple of seconds and then return to normal. Once done and normal, tap the back button and the SIM Unlock Helper should show SIM Unlock Results. If it says Successful, hit back button then show Device Verified, Root Available etc menu again. Then reboot the phone manually from power button

    Step 5 -
    Once Rebooted, Insert your SIM Card of your GSM Carrier and go to your Settings> Mobile Data> Network Mode. Once you tap that, Tap GSM/UTMS Only. If successful your phone will switch from Sprint to the GSM carrier. All there is next is to setup your APN settings to be able to receive the carriers data services.

    Step 6 -
    delete the modded file HTCOMADM_SPCS.apk
    And rename the original HTCOMADM_SPCS.apk and HTCOMADM_SPCS.odex to original state which we renamed in previous steps to avoid vdm client stopped error

    Step 7 - optional
    Changing signal logo to H or 3G icon
    open root explorer then open in text editor file default.xml from /system/customize/ACC
    Scroll all the way down find this line <item type="integer" name="sku_id">10</item>
    Change the number to 42 and save
    reboot

    Thanks bro, u really helped me and i love you .
    So may be i can help the others.
    If u press start button and nothing happens? May be u forgot about permissions ( long press on htcomadm, which u placed in system/app and choose permissions. It must be on first column - RW, second - R, third - R)
    Thats what helped me and i hope it will help you too

    Hello guys
    I just bought a US Sprint Version M8 and It is driving me Crazy.
    I still am not able to unlock it. HELP HELP
    My device is htvdev boot loader unlocked.
    S-off
    Rooted as well
    I first tried the Universal sim unlock method via http://www.sieempi.eu where you flash in the config.dat file via simlock option, everything failed except it said successfully applied imei code.
    I popped in a foreign gsm sim card, still it was locked. Nothing happened
    I than proceeded with the SuperCid 11111111 trick, I was able to change the code successfully.
    But when I tried in ma foreign sim card. Nothing worked.
    After doing the above two steps I than tried the HTCOMADM_SPCS.apk mod trick on my currently installed stock rom.
    I renamed the original HTCOMADM_SPCS.apk and HTCOMADM_SPCS.odex to something else
    And pasted modified HTCOMADM_SPCS.apk and changed permission to rw-r-r.
    I ran sim unlocker helper program, granted it SU rights reached the page with the start button but when I press the start button no pop up window appears. Nothing happens at all.
    I than decided to flash my Stock Rom to BSC_Stock_Rooted_M8_RLS_21 Rom
    I tried the same trick and switched the original HTCOMADM_SPCS.apk with the modified file.
    I open sim unlocker helper, grand su access and it takes me to start button but when I press start nothing happens still.
    Now with the new Rom when I pop in the sim card I get Invalid Card. Please contact customer care.
    Note: I also changed the network to gsm only directly via the menu and also by using the #*#*4636*#*# code
    Attached is a screen shot :

    Can someone tell me what am I doing wrong?

    Try the following on you responsibility
    - You should know your SPC, you can read it with CDMA Workshop or CDMA DFS Tool.
    - Install QSPT (http://xdaforums.com/show....php?t=2263391)
    - enable diag mode ##3424#
    - open QPST configuration, from port tab add your device diagnostics port.
    - from start clients tab choose service programming then ok & click on read from phone.
    - on system tab choose automatic for roam preferences.
    - on UMTS System tab choose any for pref service domain & any band (last bottom right) for proffered band.
    - click write to phone, then your device should work on GSM mode with modified HTCOMADM_SPCS.apk.
