Backup ROMS for Tmobile MDA - 8125, K-JAM, P4300, MDA Vario Software Upgrading

Sorry about the noob question but I have looking for this solution and seem to find bits and pieces of the answer but not the whole thing. I know if you unlock you T-Mobile USA MDA phone and update the ROM you void your warranty. I was looking to see if there was software out there that allows you to unlock and then back up Your original ROM. This way you can try out other roms but still have the ability to downgrade back to your original ROM and locked state, just in case something is physically damaged on the phone you can still have it fixed on your warranty.
I have seen the lokiwiz software posts but have not seen anything that explains the steps to take to unlock and back up. Then upgrade and restore.
Like I said this is a total noobie and defiantly not a developers question but any help would be appreciated.

Help would be appreciated... New MDA to upgrade

Hi Guys,
Firstly, i am new to this - so if i ask any stupid Q's, please forgive me
I will be getting my MDA Vario tomorrow, and before i do too much customisaton and transfer my phonebook over, i would like some advice on upgrading.
From reading this Forum, i believe that I have to do a CID unlock and a SIM unlock. I am familier with a SIM unlock, but what it a CID unlock?
Also, from what i can gather, in order to do this - i have to downgrade to an older version of the rom first. Once i have done this and unlocked the device, does anyone have any recomendations on what ROM i should upgrade it to? I have heard the Qtek rom is a good one, but will is this the best one to be going for?
Thanks for your input guys. You can be asured, once i get familier with this device i shall be providing much imput to this forum!

Hi, I'm new to WM5/vario as well (experienced on palms & treos).
You only need to unlock the wizard if you want to use another suppliers SIM card, and to get rid of the T-Mobile stuff you need to remove the Carrier ID (CID), so you can then change the rom to another one not recognised by your TMobile rom.
I understand, but could be wrong, that you only need to down grade if your device already has one of the latest a2dp stereo roms with push email built in.
Hope this helps (if I'm right)!!!

Has anyone CID ulocked and had it not void the warranty

Ive been looking for a while and no one is actually sure about voiding the warranty. Has anyone done it and sent it in? Can some one explain about cid unlocking a little. Reading the other posts just gets me (and im sure others) confused

Let me make it simple... CID Unlock voids your warranty. period. The question comes in that when you try to do warranty work is whether they will notice or not. I've heard some say they don't, and others have said they do. So in a nutshell, just understand that you ARE VOIDING your warranty. You may or may not be "caught" though if you try to get warranty work, but you made the decision to do something that voids it, so you have to live with that choice.

If you can't read and understand this post:
http://forum.xda-developers.com/showthread.php?t=285435
then you have no business doing this procedure. Dr. P has written an excellent post that takes you through the process step by step. Very simple and even tells you what to look for as you do it. There is no point trying to explain it further as it would be the exact same post as Dr. P's since it lays it out step by step in full detail.
ok, thank you.
now just one last question, i have upgraded to the newest tmobile rom, and i read somewhere that by doing that it unlocks somthing, did i read wrong?

I'm not aware of installing the newest (2.26?) TMobile ROM unlocking anything. You need to do the CID Unlock procedure and then finish by installing a rom like the TMobile 2.26 official rom. But jsut installing this rom doesn't unlock anything, just gets you to a current stable base to work off of for doing custom roms (very important step that too many people seem to be skipping).

Re-locking a 8125

Sorry if this is first grade material, I've only been working with PDA's for a matter of weeks.
I've gone over the CID/SIM unlocking threads, and I tried using WizBackup to backup before my first attempt at upgrading. Unfortunately my motherboard seems to have a conflict with the program and I can't backup. So my question is, If I unlock, then after upgrading decide to put it back to stock and use the official Cingular 2.25 rom will that lock the CID/SIM?
The only reason I ask this is incase I ever have to send it in for repairs from the occasional drop or something off the wall like that. Oh, not sure if it even pertains to this question or not, but I have a G3 phone.
Thanks in advanced,
Joe

No ! once SIM/CID unlocked,it'll remain unlocked,it won't get SIM/CID locked again if you reflash the official Cingular 2.25.But yes,if you want to re lock it,this can be done by flashing back the CID Lock_backup.bin code through lokiwiz02b,which will be generated at the time you'll SIM/CID unlock it with lokiwiz02b tool.you must save that lock_backup.bin,in order to re lock your phone and flash back the official cingular rom,it'll be back to it's official default status.
Cheers !

Am I right in thinking...

Hi all, sorry for being such a newbie, but...
I want to buy a Diamond locked to the Orange network, UK. Am I right in thinking the following...
1) The only way to get this phone unlocked is to pay for software (As mentioned elsewhere on this forum).
2) Once unlocking software is purchased, it comes with other software which de-brands the phone and replaces the Orange firmware with the HTC original (or at least, a cooked version thereof).
Thanks for all help received !!!
P.S. I did try searching for these answers myself on the forum, but kinda lost the will to live whilst reading page 6 of a 16-page thread, in which people appeared to contradict one another - So I thought I would just ask the experts and get a simple yes / no !
1) Not strictly the only way, but the simplest and cheapest.
2) No, you can leave as is, or you can just put whatever you like in it, and that's whether or not it's locked to Orange...
I'm still locked to Orange (no intention of changing given the great deal I got), and I've already flashed to the latest HTC original 1.93.405.1, I've tried a variety of radios, and am currently back to 1.00.25.05, (the phone originally came from Orange with a 1.00.25.03 Radio).
1. why get a phone from orange and then want to unlock it.why not use it on orange.
2.you can use any rom on here with it locked to orange.i use swiftbl 6.0 and
mines still locked to orange.just follow instuctions on how to flash rom on here.it is easy dont worry about it.

1. Because, obviously, his intention is so.
Hi,
Thanks for all the help.
I didn't make myself very clear above. What I was trying to say was that I am going to buy a phone which is (briefly) used, but comes with a 1-year guarantee. At present the phone is locked to Orange and I wanted to unlock it and rebrand it because...
1) Orange are alot dearer unless you tie yourself into a (min)12 month contract
[Something which I def. dont want to do !]
AND
2) Orange usually (or at least used to) personalize a phones firmware with their own menu system/ icons etc. Which again, I don't want, because the phones original/generic firmware is usually better IMHO.
I was hoping that the unlocking & de-branding may simply have been a case of flashing the phone using existing software - but oh well !!!
Actually, just a thought - the Orange phones do come locked don't they ?
Orange phones are locked, yes. But with the Diamond, it's unbranded so no real need to flash the ROM unless you want to improve upon it's working speed
Flashing the ROM is pretty easy and all the software is free and available on this site in the ROMs section.
Unlocking the phone means paying for an unlock code which isn't usually that expensive.
keep in mind that this will void your warranty too

Is there no way of backing up the original rom before overwriting it ?
Thanks

[Q] Bell HTC Raider LTE - Not recognizing Sim

About a week ago I received notification to update to ICS. After downloading the file and the phone upgrading it get locked into a boot loop, then after about 14 hours it finally escapes form the loop and starts up only to have the SIM not get recognized, I tried restoring to factory default but it didn't work... I then sent the phone to Bell to get repaired but now they are asking for $200 to fix the phone as apparently the bootloader was unlocked and voided warranty.
As you can guess I'm saying "screw you" to that and trying to fix myself... I'm not experienced with android and when I originally upgraded I didn't back up my original software so i have nothing to restore... So basically right now I am wondering what I should do... the phone is being returned to me not repaired and I want to fix this but don't have the knowledge how to... I'm not dumb when it comes to unlocking phones as I used to unlock old Nokia's and jailbreak iPhones but I have no idea when it comes to Androids.
I'm guessing I will need to try and find an official ROM for this but Bell canada isn't the most open with their OEM software so I was wondering if anyone could help in this area by providing a ROM I could use... secondly I guess I will need to S-off my device in order to install the software?
I have searched the forum to find somethings that may be relevant to what I'm trying to do... but I'm getting confused as to what i should do (The curse of being a Noob)
Any info would be great... thanks
Read through this thread: http://forum.xda-developers.com/showthread.php?t=1668259
Quick summary: you have to be totally stock (relocked bootloader, unrooted, S-ON) to run the update to ICS via Bell.
Thanks... will give it a look through and see if I can recover this way.
