Problem SOLVED!!

Problem Solved!

(Please observe I assume that you know what you are doing and know the basic stuff regarding the phone, I am just a beginner like you)

Please remember all this will erase everything you have on the phone.(back it up)

You need the following:

-MircoUSB cable(for connecting the phone to computer)

-Zune installed on your computer (BUT DON’T RUN IT UNDER ANY CIRCUMSTANCES) (you need zune for installing Modem drivers on your computer)

-Windows Phone Developer Tools installed on your computer (for deploying /sending software to the phone when you are done jailbreaking it) I will get back to you on how to put apps on your phone the “Sideload” way

My phone has PC40100 and SPL 5.10 (so in theory it is not possible to install Cooked firmware)

What I did was the following:

1. Put the phone into Boot (hold down volume down and power at the same me when the phone starts it is like IOS DFU nothing major happens. Now you can see tri color (red,green and blue) on the white/bottom of the screen you can read “serial”)

2. Connect the phone to the Computer using your USB cable , and if you hear a you’re your computer you know it is connected to computer and your “serial” changes to “USB” on your phone

3 Downgrade the phone with RUU_Spark_HTC_Europe_5.10.401.06_SLSPL_Signed_by_ansar (search it on the forum)

4. Now the phone restarts into tricolor /DFU and nothing more happens , it is not dead just needs to be programmed (if you do nothing it will eventually reboots and windows phone starts, don’t do that it is just a waste of time, keep it in boot)

5. Choose the STOCK (stock means the released original firmware by HTC/Microsoft ) version of windows phone RUU_Spark_HTC_Europe_1.10.401.04_Spark_5.52.09_RELEASE (search it here on the forum) the 1.10.401.04 works fine with the jailbreak tool from DFT (dark force team)

6 . Install the stock version it will downgrade your phone from SPL 5.10 (SPL stands for the original boot of the phone ) to SPL 1.10.401 this is what you want

7. when it is done your phone will start and it looks fine but if you check the system in settings you will find that it is SPL 1.10.401 and the multitasking is gone.

8. REMEMBER DON’T connect the phone to Zune it will just update it and ruin everything

9. Now you need install RSPL /HSPL on your phone to be able to install cooked firmware (cooked means someone else like Ansar(a user here) has done all the work and removed the locks in the original firmware and made it easy for you and me to install software on the phone which is called by the way “sideload”)

10. DFT (dark force team has a jailbreak for boot which makes it possible to install cooked firmware)

11. Search and download DFT_XSPL_WP7FG1

12. You need to install RSPL first to be able to use HSPL (HSPL is more permanently like untethered jailbreak in IOS)

13. Put the phone again into BOOT mode (with tri colors) and connect it to the computer and run DFT_RSPL_WP7FG1_LAUNCH from your computer (just follow the onscreen instruction from DFT teams software and choose 1.10.401 it is imperative that you choose this for this jailbreak to work)

14. when it is done you will see RSPL on the screen of your phone (you are actually done here if you don’t want to lose your warranty but I doubt you have some left if you do GOOD for you , RSPL is reversible but HSPL is not)

15, in my case I went ahead and installed HSPL just to be safe it works , cause RSPL disappears when the phone is shut down. I just installed HSPL when the word RSPL showed on my phone but it is optional if you want that or not.

16. From where you see RSPL/HSPL it means your phone is ready for COOKED firmare NOT original/stock firmware REMEMBER THAT installing stock/original firmware will brick/destroy your phone, every page in this site says it DON’T push your luck

17.Install any Cooked firmware from Ansar (a user named ansar look him up and don’t forget to thank him for all this work) for instance HTC_Europe_5.12.401.06_Radio_5.69.09.05a_22.50.50. 21U_NT_Mango_8107_22L_TU_by_ansar (which is the latest )

Remember if you have any question I will be more than happy to help but I am just a beginner, you should ask Ansar directly here.

DISCLAIMER you do all this on your own risk.
