So I'm almost ready to jump ship and upgrade the original rom on my Bell PPC 6800. The question I have, is can I revert this back to the default state if needed. Original Rom/ Boot Loader / Radio / whatever else? Can I make a backup of these from my device prior to flashing?
Thanks

Gotta read brother, nothing comes easy. Check the upgrading thread instead of this one.

Backup is not going to work the way you think, you need to find the virgin rom and radio instead of imaging or something else you may be thinking.

Hi all,
Sorry if this has been covered elsewhere, i've had a look round but couldn't see anything.
Is there a way to backup or extract my current O2 UK Rom? I totally srewed my motherboard last time i tried to use another rom on my xda orbit as it wasn't cid unlocked. doh! Anyway i've had my motherboard replaced by O2 and was planning to get my device CID unlocked and install another rom but i would like a backup of the original O2 UK Rom just in case it all goes pair shaped.
Oh yeah forgot to mention that i currently use spb backup to backup my device but i dont think you can restore the image from the bootloader menu.
Thanks in advance.

Not as of now,spb back up works for phone data etc not for rom images,lets hope someone comes up with a solution soon.
I really want to slit my wrists
I am currently in the process of doing a warranty exchange on my Hermes with AT&T. I loaded a cooked rom too it and obviously change the bootloader. I know I need to reload a carrier supported rom but should I load an original bootloader to it as well?

If you are taking it in for Warranty Replacement, I would get it back to original specs if possible... Anything that isn't carrier loaded (as far as Rom and bootloader) must be reverted to original, or you may have difficulty getting it replaced... As always, when in doubt - put it back...
When did you update? Did you use pof's Unlocker v3a? Then I've got exactly the same problem (except my original CID is different I think). When pof has time the next days he'll send me a program that restores the CID he said. You could PM him and ask him to do the same for you. I think he'll read this thread as well.

If the OP has loaded a Radio version with HTC_Boot 0108...he wont be able to get his CID back, you should be ok since it looks like you have an early radio with HTC_boot 0107.
I am in the situation that I want to go back to the original Magic ROM. Where can I find it and how will I back to the original and not rooted ROM?
Any One?
Am told that it is not easy to get it rooted, but I will at least just like the original ROM
I'd like to do the same! I rooted my phone with Haykuro's Magic rootme ROM and all has been well for weeks but now I'm receiving an OTA and it just keeps downloading without installing. I know I should have done a nandroid backup but I didn't and now I can't go back unless anyone can post a link to a stock HTC Magic ROM image (uk vodafone would be ideal but any HTC or Google standard image should be OK). Has anyone done a nandroid backup of a clean phone and willing to share it? Thanks in advance.

I've not tested it myself yet.
Bit of a basic question really for all the Orange users out there (and crossposted a little) but by rooting is the warranty on a contract phone invalidated?
Basically before doing any kind of flashing to new roms I want to backup (simple - incase anything goes wrong but also so I can "preserve" any warranty by going back to the original Orange state), but to backup using Nandroid you need to root first (correct?) - so my concern is if by the process of backing up you are breaking the warranty anyway...if it's worth it.
Not sure if you need to root to Nandriod Backup. I thought you just :
1) put the phone into recovery mode (power-off, hold 'back' and power-on)
2) did a fastboot boot cm-recovery.img
3) select backup from that menu.
TBH, the first thing I did was root my Orange phone and THEN started playing with ROMS, so I could be wrong.
A pristine (non-rooted) Orange ROM is available from Modaco's site if you need to revert. Also, rooting simply changes the ROM. I'm more woriied that's I've unlocked the phone!
Hello,
Yea this is all pretty new to me however it would indeed seem you don't have to root to do a backup (which is perfect). I just figured it's best getting a back up how it is now before *any* changes are made.
I don't know anything about doing a fastboot though, could you point me in the direction of a newbie guide or something?
Also I didn't know the original Orange ROM was avilable - that's very useful to know! Thanks!
Fastboot documented here

Probably need to install the Andriod SDK, too:
http://developer.android.com/sdk/1.5_r3/index.html
SDK 1.6 is available, but I don't know if that causes any isses - I use 1.5.
Lots of good info on:

Good Luck!

Hi CombinedEffort
I've got an Orange Hero that is SIM & CID locked and as such I cannot download the official HTC ROM update. I have already nandroid backed up and rooted, but I not too sure about flashing new ROMS (ie. Modaco's). As you say you rooted then started playing with ROM's so hope you can answer a few questions.
-Did your Orange phone come from Orange direct and was SIM & CID locked?
-How have you unlocked your phone? Was it just a SIM unlock code, or have you managed to CID unlock too? (I've seen a thread http://forum.xda-developers.com/showthread.php?t=559806 about CID unlocking that requires you to make a serial debug cable - something I'm trying to avoid, but will to do if need be).
-Even if you haven't CID unlocked your phone, were you still able to flash custom ROMs, as long as you don't flash a new radio?
-Did you use the "update.zip" method to flash new ROMs?
Sorry for the number of questions, but hope you're able to answer them.
Can't wait to get rid of the stock ROM
Cheers

I was under the impression that the process of rooting thereby allowed you to use other ROMS such as the offical HTC ones - if this isn't the case I'm also very interested in more information!

Well I took the plunge and flashed MoDaCo's 2.2 ROM. Looks like you were right, you can flash ROMs if you've rooted your phone. However I'm still not sure about flashing radios if your phone is CID locked - I got the impression this wasn't possible from other threads I've read.
So go right ahead and flash ROMs till your hearts content - don't forget to do a backup 1st though, just incase.
One issue I have with the new ROM though, I can send SMS but can't view the threads afterwards (just says "loading") also when receiving SMS I can't see them. Me thinks some investigation is needed

I bought mine from Dial-a-phone with an Orange contract. It's Orange branded and was locked to the Orange SIM

I unlocked the phone with http://hero.unlock-now.com/sim-unlock-HTC-Hero/
adq (Andrew de Quincey, by any chance?) hadn't posted his CID unlock by then, so I know nothing about that.

I did flash generic / custom ROMS hoping it would unlock the phone - it didn't, but I could still use the Orange SIM with the generic ROMS. Not sure how flashing the radio would affect this - I would have thought it wouldn't

No, rooting affects the *ROM* not the *phone*. Modaco's custom ROMs come pre-rooted.
I came from an iPhone 2G background where I was expecting to have to Jailbreak and unlock the phone before being able to do anything useful with it. This is not the case with the Hero. Out-of-the-box, you can boot the Hero to the bootloader and flash a custom ROM from there - VERY hacker friendly!

Hey guys,
I have a few questions about unrooting my HTC Legend, just in case. So I went to the thread "Easiest way to unroot HTC Legend" and it was a straight forward guide. I just have a few questions. The guide gives you a link to 1.03 software version, and 2.03 software version to unroot to, and all you have to do is reboot your phone while holding down the DOWN volume button. If I were to unroot (Just in case for emergencies) I would choose to roll back to 2.03 software. I'm on software 3.15 and was just wondering if this will roll back successfully to the stock ROM for 2.03? Will my stock ROM after unrooting be Android 2.1? Will my phone's radio version change? That I don't want at all. Just wondering because if for emergencies I need to unroot my phone then I need a stock ROM and software number that are out here in Canada, currently my phone has Froyo which isn't out for us yet. I wish I could put up a link but I can't, I was told before I'm not allowed to. But what I explained about the guide is everything you need to know just in case you don't. Thanks for the help guys.
I'm not sure about the firmware given in the guide, but those RUU files usualy contain radio too..It can be extracted from it, but I think that radio from froyo might not work with eclair rom you'd roll to...But as this is just in case, I think you have plenty of time to find out
Sent from my HTC Legend using XDA App
Actually the Froyo Rom I got didn't have another radio file in there, it kept the one I had with Eclair, so I'm sure it'll work. But what is a radio file do? I actually forgot to ask that, I always knew that it's needed but I actually don't like it when it gets changed, just because I was told if I flash the wrong radio, my phone will have problems. What happens when you change a radio file?
Anyway, there are versions of radios that do not work with certain ROMs and vice versa...
Radio image is an intermediate between android system and a GSM/CDMA/3G (phone) hardware...it is referred to as a RIL (Radio Interface Layer) it sort of acts like BIOS on PC, just between certain hardware and in your phone's software...
And yes, if you flash a wrong radio, you legend can act up like not being able to make a call or establish data connecttion, no wifi etc...
As Canada doesn't run GSM as far as I know, I'd be very carefull about radio firmware.(most radios here are WWE or Vodafone UK based and I'm not usre if it'll work out there )
You can check the zip files you update if they have radio update in them - easiest way is to remove the radio.img and re-sign them...
I actually used an RUU to root my phone that was WWE, with "Theunlockr.com" and it was used to downgrade. So I think WWE would work. If I use a Nandroid backup and something goes wrong such as wrong radio version, and restore the Nandroid backup, will everything go back to normal? If that's the case then there's not much problem in taking a risk. How do you know if the radio version if right for the mobile carrier though? I'm guessing that's the hard part of updating software? :/
