Rom Downgrade

Hi all,
I own an I-mate Kjam with an official ROM 2.18.9.1 ITA. I would like to flash my kjam with a not official ROM, because they stopped to upgrade this device.
In order to flash the new ROM I should need to CID unlock my device and to do this I should downgrade to the ROM 1.xx.x.x.
I tried to do that but an error occurred and stopped the process. This error come out because it isn't possible to downgrade from this Rom version (this is the meaning of the error message). The same is written in the I-mate official site, "it is not possible to come back from this ROM version".
Is it possible to find out an alternative way the flash my device?
Thanks in advance.

Hi Jhonny,
Yes , i was followsh4d0w86 step by step instrunctios and go to this link: http://forum.xda-developers.com/showthread.php?t=1411904
after i downloaded RUU_Schubert_HTC_Europe_5.10.401.04_SLSPL_Signed_by_ansar i got the error message.

hi erezhavida
you get that error msg when rom is wrong region
you have to find earlier rom for your region
your Firmware number :2250.21.51003.206 last number...206 is your region
look for older stock rom ending in 206
try that....that should then downgrade your HSPL
cheers and have a gr8 day

hi...
I recently bought a new hd7 but while downgrade spl i half bricked my phone.
But using the goldcard method i was able to re alive my phone again.
you first see that what position is in your boot loader screen then you will use next methods. This goldcard method is for half bricked set where you will not see any serial option in bottom.
Your can use your device but can,not install rom anymore.

Be careful with just trying to flash rom versions, you can damage the bootloader and brick you device.
What is it that you are trying to do exactly?
Are you wanting to install a custom rom?
What method are you trying to use?
With a 5.xxx bootloader you can only use the goldcard/ Y cable method to flash your device and downgrade your SPL, unless you have a pre-mango Zune backup/restore point on your computer, then you can use that also to downgrade you SPL.
Let me know what your trying to accomplish and I'll try and help you!

Hi, xdrc45
Exactly I want to install Nextgen 3.4.
I'll trying to install official rom & and custom rom too.
In my planes firstly roll back to earlier versions (because HSPL installer says that required version firmware is not higher 1,6.....), then install HSPL & finish by installing Nextgen 3.4.
Can you help me step by step what I need to do?
Many many thanks for the any help!

You have to lower/downgrade your SPL to at or under 3.xxx to install RSPL/HSPL then flash Nextgen.
With 5.xxx SPL you can only downgrade your SPL in two ways.
1. Goldcard/ Y cable method, requires you to make a "Y" cable made out of 2male and 1 female USB cables and you need a SD card reader/flash drive.
2. Pre-Mango restore point, (Zubair's method, in Shadows tutorial) meaning you upgraded your device from a pre-Mango version to Mango and to you have the computer that you did it on.
Follow Shawods tutorial here, it explains all the above, How to downgrade SPL, flash XSPL and install a custom rom.

[Q] deepshinning is possible with 4.x SPL?

Hi,
I am newbie. sorry for that. It tells me that I need flas a NODO rom first to Downgrade SPL
http://forum.xda-developers.com/showthread.php?t=1271118
I have mango with 4.x version.
1) I think I need to downgrade to NODO first?
2) "flash a NODO Rom first to downgrade SPL" - does flashing Rom means downgrading also? or I need to flas first and then I can only downgrade to 3.x, 2.x, 1.x versions?
3) which SPL version I need exactly? as I know I can flash Rom with 4.x as well. It is not sufficient?
4) Shubert is for flashing or downgrading based on the version if question one is not same?
5) I am in Europe -Germany but I use DE_O2. which version I should use? DE_O2 means O2 branded phones or if I use O2 as provider only. because my card is O2 but phone is not O2 branded.
thanks for the answers.

There is a thread that explains the answer to most of your questions, I think: http://forum.xda-developers.com/showthread.php?t=1295068
Also, the wiki helped me a lot too, so search HTC HD7 on that. I still haven't been able to flash mine (problems with the microsd card reader, maybe).

From what I understand, by downgrading your ROM to an early version, you also end up with a downgraded bootloader. The OLD bootloader is the only one that is capable of allowing you to flash a custom rom such as Deepshining. In order to downgrade the ROM, you need to create a goldcard or use a similar method (there is a method for European devices that apparently doesn't require you to use a Y-Cable/Goldcard, here is the thread on that: http://forum.xda-developers.com/showthread.php?t=1411904 but make sure you completely understand your options first).
Read the replies to see if anyone else had experiences with DE_O2.
