Upgrading Rom on a G4 8125 Cingular Phone to latest Molski

I`ve been reading a lot of threads, but`m not able to find, a guide to check if my G4 phone is CID unlocked or not, i already know that is SIM unlocked.
But how can i check the cid unlock without bricking my phone??
Also, after that, should i go directly to execute the upgrade, or i need to use the lokiwicz soft...
Thanks

Paid CID unlock

Just out of curiosity:
If I buy unlock code from say IMEI Check and CID unlock my device, would I ever need to run Hard SPL or Soft SPL to upgrade/downgrade my Trinity? Then going forward, can I just run any custom/cooked/original ROMs without worrying (since my device is permanently unlocked)? Please don't ask me why I want to pay for this when there are so many free alternatives - I don't know the answer
Last but not least, which method of unlocking preserves the warranty? Can the device be locked back just in case I need to take it to service?
Thank you! (I know these qns have been answered many times in this forum, but I just want to reassure myself that I got it all correctly)

As far as I know, IMEI-Check will completely unlock the device, allowing ROM upgrading etc without the need for additional hard SPL or softSPL.
Unlocking in itself doesn't affect the warranty, so you could simply use IMEI check to unlock for use of another SIM card. Further than that, flashing a new, unofficial Radio or OS ROM will technically invalidate the warranty. Most of the free unlockers actually work by flashing the Radio ROM, so in that case IMEI Check is safer as it retains the original ROM.
Once unlocked, there is no way to relock a device, but as long as you have the Operators own ROM in place, the lock status won't be looked at.

Yes, you'll also need to use SSPL / HardSPL if you plan to flash cooked roms (unsigned) in NBH format using the RUU updater.
You'll not need to use SSPL / HardSPL if you plan to flash shipped official ROMs (signed) using the RUU updater or if you you extract the *.nb files from the NBH upgrade and flash from mtty using LNB command in imei-check's MFG bootloader (which doesn't check signatures). You won't be able to flash unsigned code with the standard RUU Updater or SD card using imei-check's bootloader.

Original roms yes, you can flash them without worrying, but you'll have to re-run imei-check's unlocker everytime you want to flash your device with an original rom not matching your CID as CID unlock is not permanent (it disappears when you flash the radio).
As for custom/cooked roms, no, you'll have to worry about a) using HardSPL/SSPL or extracting the *.nb from NBH and flash from mtty, as it's the only way to flash unsigned code with imei-check's bootloader.

- imei check, as long as you replace the bootloader with a standard one before returning your device
- free unlocker, as long as you don't check the "superCID" option when you run it and you flash a standard radio back into it after SIM unlocking.

Depending on why you have to take it to service, but basically yes if it's working.

It will SIM unlock, but the CID unlock will only stay as long as you don't replace the RADIO after unlocking. If you flash another radio, then you'll need to re-run imei-check's unlocker again to have it CID unlocked again. And remember that for flashing a cooked rom you don't just need a CID unlocked device, but also need to bypass signature checking.

But it replaces the SPL on the device by a 1.01MFG SPL, so the warranty is technically void. And it also modifies the radio, but keeps the existing version.

That's not true

That's true in most cases.

Thanks Pof

Thank you very much, pof! That's clear and exhaustive answer!

Please help a noob - never upgraded a ROM before

Hi People
I am new to upgrading. Before I get the business of "you have not read the posts" I have read the posts. That's why I am writing here. The more I read, the more contradicting it is. I have the following:
T-Mobile MDA Unlocked SIM
IPL/SPL 2.26.0001
GSM 02.25.11
OS 2.26.10.2
I know this is a G4, but I have read that you can flash a ROM to an locked CID, but other areas say you cannot. I also have seen many different guides to flash, but some say the CID have to be unlocked others don't. I also have not seen whether the original ROM is saved in case you want or need to put it back. I have also read that you may have to input the GSM settings (I use Rogers in Canada). I bought this unit on eBay unlocked and all I had to do was put in my SIM card and it worked. Will the same happen if I upgrade the ROM? I find after reading so many threads it seems so confusing and was hoping someone here could help me out as you all seem to love flashing ROMs.
Thanks so much in advance,
Mike

hi,
ok,now let me try to explain in plain words,
1. U cannot for sure upgrade to a newer rom untill u r CID unlocked, now as u say u got ur wizzard from ebay.now it must have come with a pre-installed OS,plz check from which carrier it is from.If its Cid locked than it can only be upgraded with that official rom from which it came pre-installed with. But if u want to upgrade to some other wm6 cooked rom than u'll have to get it Cid unlocked.
now to upgrade,do the following:-
a)If u want to upgrade with official rom from which it came preinstalled,than visit the official site and download the official rom for ur exact device and upgrade without any Cid unlocking process ,its fairly self explanatory,how to upgrade with official rom as it comes with a self upgrade romutility.
b) if u want to upgrade to any other wm6 cooked rom,than i'am afraid u'll have to CID unlock ur device.As u say u have a G4 device there's a different procedure to Cid unlock it than G3.It's done with a utility tool called SHELLTOOL.search and read how to go about it.First download a tool "WST tool" by Mestrini ,install it and check if ur device is Cid locked or unlocked.If u find it locked than adopt the Cid unlock method through SHELL tool,if its already Cid unlocked than go ahead & flash with any wm6 rom.
As for ur question about sim unlocked,its different being from CID unlock.with sim unlocked u can put any carrier sim and use ur device.But with Cid unlock u can upgrade to any rom u desire.
Well, once SIM/CID unlocked it remains unlocked forever,unless u personelly don't lock SIM/CID.
Well,I believe if it came SIM unlocked, than it might be CID unlocked also.cuz all the carriers never give Sim unlocked.but than there might be some exceptions.therefore u must get it confirmed before any upgrade.
Hope I was able to clear some of ur doubts.goodluck

@zabardast_1 dude..
@Miker2006
Upgrading won't affect your Sim unlock status, it's permanent.
You don't NEED to CID unlock your phone to upgrade:
You can use Soft SPL to make the phone temporary think it's CID unlocked (while flashing).
Or you can semi-permanent let the phone think it's CID unlocked by Hard SPL.
This SPL will mimic a CID unlocked state, so you can flash all kinds of ROMs to your device.
BTW ShellTool WON'T cid unlock your device, Hard SPL is the closest you get to a Free CID unlock.
Best regards,
EquinoXe
PS. Read the stickies before Flashing, don't turn your wizard into a brick.

Actually it is a good show case that reading helps .. one day after his post Miker2006 did ..

question about how to keep GPRS/GSM/phone settings after wm6 rom upgrade

Ok I have searched and searched and I am about ready to upgrade to a wm6 rom. I have a cingular 8125 and its still CID/SIM locked. I just want to know once I downgrade then CID unlock then upgrade are my GPRS settings saved once the new ROM is on??? If not how to I go about getting these set up. And also, does a phone need to be SIM unlocked to upgrade or just CID. I am guessing just CID but i want to make sure
Thanks

sim unlocking is used if you want to use other carriers on your phone, cid if your flashing a new rom, they are just steps away, why dont you just do them both, and be sure to know what kind of device you have G3 or G4, you can use the network wizard floating around here for your settings, enjoy

ok, i know its a g3 i have been reading up for ages while it was in repair. but I cant seem to find the GPRS tool or whatever you are talking about. Can you point me to a thread?

xda-developers free trinity cid-unlocker, is cid lockable again???

hi,
in a german forum i read, that only the cid unlocker which you had to pay for permanently gives you supercid status. now, i unlocked my trinity with the xda-developer version ''sspl'' for free, and want to restore the original condition, with locked cid, and original rom...
is this possible, and if it is, how?
kind regards, luki
ps: i used pofs method to unlock the trinity

Hi.
I'm searching for the same question and that's why I'm still on original WM5 ROM.
Mine is locked to Vodafone PT and I'm afraid to put another ROM like Dopod one, and if I got some problem, I don't know if it's possible to return the Trinity to the original state (CID) and send it back to waranty.
I keep an eye on this post and if you find some information, please put in here.
Good luck.

I don't think that you could CID locked your PPC !! But if it's just for going back to warranty...Often, they didn't see anything if you reinstall the original Rom ...

Are only branded trinitys cid locked ? what is cid lock ?

CID = Customer Identity
I don't know exactly why CIDs exist but i think it has something to do with licenses and stuff like this.
And no, original HTC devices have a CID lock too.
But @ shym I think you shuold watch out for the CID bypasser, I'm pretty sure it doesn't unlock your phone but you will be able to flash other ROMs anyway...

That's exactly what I'm looking for.
A way to flash another ROM, like Dopod or coocked one, and if I don't like or need to go back to WM5, just put the operator (Vodafone) original ROM and returnt it to warranty, if is the case (hope not)
Don't want to risk my Trinity to loose the warranty if the service found the phone was CID unlocked or else.
