I recently rooted using unrevoked on a mac, and am now running CM6, id like to go to back to my original software which was 2.1 with Sense on Telus. Is this possible, I dont mind if i lose all my contacts and apps etc. I'd just really like to go back to the software so i can rest easy. If so, can someone provide detailed step by step instructions for this as im a big noob. Thanks in Advance.

UGH???
there is no telus one??
Dont suppose you performed a Nandroid backup that you can use to restore the original rom image using some recovery?
If not, check this thread:
http://ip208-100-42-21.static.xda-developers.com/showthread.php?t=762063
See post #19 (another member packed a nandroid backup of the stock Telus rom) especially and posts on the next few pages of this thread for a link to the original Telus stock radio image for 2.1.
Good luck.

There are a few nandroid backups of telus floating around but they do not include the radio. The current 2.2 radio's floating around do not work with 2.1 but should be able to find something that does work.
When you find a backup of the original telus rom you will need to copy it to your sd card to the location where they are stored... off hand I belive it is..
clockworkmod/backup/ date and time stamp of the backup
When you get the file there you boot into recovery, move down to android and select restore and pick the date of the one you want to restore.
Honestly if you want a sence UI there are many 2.2 htc sence roms on here which are much better then 2.1.
Are you only missing the sence widgets etc? Or do you need it back to original to return it etc?
Thanks i found a nandroid back up on another thread, as well as a radio. If you could find me a 2.2 sense rom, and radio, and tell me exactly how to install from a mac that would be great, cuz im super afraid of bricking my phone, and i dont really need CM6. THanks in advance

If you are running cm6 you are already rooted with recovery. All that is required to install any of those roms is to download them to your sd card, reboot into recovery, run a wipe system then install zip from sd card, boot and your good to go.
Note: Some of them may require a ext partition on the sd card which I would assume you don't have since cm6 does not need/use it nor did the 2.1 that came with it.
MacLite and the Official 2.2 rooted would not need any changes, just the download.
You should not need a goldcard for anything.
How do i install new radio??????
If you are running CM6 it already uses a froyo radio, you don't need to change it unless you are having issues etc. You do it the same way, download it to the sd card, boot into recovery and say install zip from sd card etc. Same way you would a rom.
Also, when i reboot how long do i wait at the android with the box, before yanking battery

Android with the box? Preferably never, only time its really safe to do so is when its the HTC Logo that never goes away.
so your saying when the android bot with the box comes up just wait it out, and it should reboot into 2.2 sense?

Ok, I really want to root my Evo and install a custom ROM but Im PETRIFIED!
I use to have a motorola droid that no matter what I did to the phone I could (even if it was bricked) restore it with an application made by Motorola. Because of this I had no problem playing around with Roms because I could always "fix" the phone if needed.
So my question is, is there a program that does the same thing for the EVO, where I can restore and unbrick the phone?
Also, can you recommend any custom ROMs to use? Preferably 2.2 if every thing works camera,wifi, bluetooth,4g etc...

To unroot you need to run the HTC RUU (ROM update utility) You just your phone into your PC and run the EXE. If you have questions about it look at this post.
http://forum.xda-developers.com/showpost.php?p=7147157&postcount=10
On to ROMs the 2.2 ROM's are moving along pretty well, but they are not 100% as far as I know. As to what to recommend that is all on what you like. Look in the Dev section and find you one like and read about it.
Hope that helps. If not let me know.
Ok, so I can un-root with the RUU utility but will it work if I updated with the recent OTA update?also, if I instal a custom rom will it restore it?
Thanks

I personally have not ran the RUU, but people have unrooted even with the latest OTA. I believe
I guess I am not understanding what you mean by if you install a custom ROM will it restore it... If you run the RUU it will put you back to a completely stock state even if you are using a custom ROM. Not sure if that was the question but it was an answer
Yes, there is a way to use the RUU to get you back to complete stock.
You will be fine during the whole process as long as you follow directions, and don't do anything crazy (for example, never do a battery pull in the middle of flashing).
It's fun, you know you want to do it. lol
And also, with the custom recovery, there is a way to restore backups you make along the way
Hi all,
So I'm on O2 UK with a branded (and I assume locked) Desire.
HBOOT: 0.80
Firmware version: 2.1-update1
Rom version: 1.20.207.3
Bottom line is, I want to root before O2 push out their 2.2 update which will inevitably increase my HBOOT version. I'm a actually a software developer by trade, but I'm scared and want to take this whole rooting process slowly.
I've already created a goldcard but I've also set up my PC ready for the Unrevoked method, so I'll probably end up using that. So my main question is:
- Once I've rooted with unrevoked, do I HAVE to install a custom ROM that very minute or can I simply reboot my phone and use the stock ROM until I feel I'm ready to reflash?
Thank you! (my first post, be gentle please!)
-L
... delete
Good evening lodger. I was in the same place s you, o2, new desire and first time boot.
I used the unrevoked method, it took 5 mins and have not needed a gold card.
I have flashed another ROM straight away however my phone re booted in to the original Rom and I could continue to use it with the original o2 Rom but just with root access.
Hope this is of some help.
Sent from my HTC Desire using XDA App
Thank you for the quick replies!
So please correct me if my understanding is wrong, I run the unrevoked process and I get a new recovery rom that lets me perform nandroid backups and flash custom roms but nothing more (yet)?
So if I were to just take a nandroid backup at this point and boot the phone normally, I would see no difference until I actually flashed a custom rom with root access?
I'm actually unsure as to whether the phone is actually locked as I've been with O2 for a looooong time and never had a locked phone from them and unfortunately I don't have another sim card to try in it. The only branding is the O2 boot screen, nothing else. So if anyone could confirm the thing about needing an unlock code that would be great.
Sorry for all of the questions, I'd just like to understand the process a little better before applying it to my pride and joy

As of unrevoked version 3.0 it will root your desire and install a custom recovery.
So you'll have a stock Rom that's rooted, then you can nandroid backup and install a custom Rom when ever you want.
Sent from my HTC Desire using XDA App
I can confirm the first reply you got was wrong. Unrevoked is the easiest and best method to use. It WILL root your phone as well as install a custom recovery. You can then continue to use the stock rom with the benefits of root.

You won't require an unlock code for an o2 branded phone.
O2 phones are normally locked, but iirc you can use Orange sim cards in there too.

The only people who need an unlock code are Orange users.
As for unrEVOked, it will give you root. The handset will be perfectly usable as soon as unrEVOked is finished. You can then choose to stay as you are or play with all the roms in the dev forum.
Personally I'd jump straight into the dev section and download like a geek on speed
Thank you everyone. You've helped clarify thing no-end and given me the confidence to go ahead and join you all in root land Ok, one last round of questions:
So once I'm rooted, I can jump straight onto the market and download titanium backup and get all my stuff backed up, then I'm pretty much good to go right? (I'll feel a LOT happier once I have a backup!)
Any recommendations as to which rom I should go with first? There are a LOT out there and as a newbie to all of this, sifting through them is a tad daunting.
What's the deal with radio updates? Is there anything I should be aware of when applying them? Should they be applied first, before the OS rom or the other way around?
Having already created a goldcard, is it worth hanging onto it? I hear they do come in handy.
Again, sorry for all the questions but I figure it's best to ask them now rather than get stuck further down the line.
Thanks again
-L
Update: I'm rooted! nandroid backup is running now! Phew!
Thank you again everyone!

It depends what your looking for in a rom. If you want froyo with sense you could try ones by pays, or the leedroid one. If you want plain android, I'd go for defrost by richard trip, or opendesire by adamg.
You will need the latest radio for the new froyo roms for stability and to ensure no echo during calls. The radio is the baseband that you see listed in about phone. It will also increase your wifi and mobile network strength.
When flashing the radio your phone will reboot twice. It is extremely important that you do not interrupt the flashing process and if it looks like it's frozen or whatever, just leave it, and be patient. The radio flash is perfectly safe, but if you do interrupt it you will have an unrecoverable brick!
Titanium will work as soon as you have root, I'd get the paid version if you have a lot of apps, as the free version requires you to confirm each app install one by one, paid version is fully automatic.
Finally, if you want to put your apps to sd card, then the froyo one is rubbish! Most if not all the custom roms use oldschool a2sd which is far better but requires an ext3 partition to be made on your card. To make the ext3 partition use either the custom recovery you have from unrEVOked or download rom manager from the market. The process of creating the partition will ddelete your sd card though so take a backup if needed.
Hope this helps you a bit, and good luck. Once you have tried a few roms you will love it

This is wrong, Orange users must use a compatable radio meaning there's no need to unlock.
As for you, if your phone is locked then you will need to flash a compatable radio like orange users. I'm not sure which radio versions o2 uses so it may be worth googling or checking which radio your running. In future when flashing a custom firmware use one that doesn't have a radio file bundled with it.

Unless something has changed you are incorrect. Any radio updated away from the stock one locked orange handsets. No other networks are affected.
All froyo roms require the latest radio. This is not optional.
Something has changed because I have a locked orange desire, with the latest radio running the latest open desire firmware and have not had a sim lock message.
I wouldn't of said what I did if I wasn't sure
Best custom rom is neophyte 1.6 if you want sense froyo
Well I guess the only way to find out will be to pop a different sim in and see what happens. I haven't yet seen anyone with an O2 branded phone with problems flashing to froyo on my forum travels, but I guess its worth finding out for sure. I'm prepared to pay for an unlock code if need be.
So would I be better off using clockworkmod to flash to 2.2 or Rom manager? I assume I have the choice now?
I've taken a titanium backup so now all I have to do is put the radio and os roms on the root of my SD card, flash, *pray* then restore my apps after it reboots?
Thank you again to all. I wouldn't have done any of this if it wasn't for you guys taking the time to help me understand this whole process. I prefer to know more than just "Follow these steps and this happens".
-L
Well I finally grew a pair and flashed neophyte 1.6 and i'm proper impressed! Thank you to everyone again for your help and advice.
For the record, I didn't need an unlock code. I just flashed the latest radio and rom straight after each other in clockwork and rebooted. That first boot is a loooong scary one but it was all good in the end
Thanks everyone!

It was by far the scariest thing I've done this year!
Only thing I seem to be having a problem with is Juice Defender + Ultimate Juice (if anyone uses it?). When Juice Defender disables mobile data depending e.g. when the screen is locked, it keeps coming back on by itself which just adds to the battery drain. I've scoured setting after setting in case there's something forcing mobile data back on after JD disables it but found nothing. This used to work perfectly before I switched roms and it's kinda frustrating.
I'll probably have to try a couple of roms until I find one that works well with all my apps.
No, UnrEVOked doesn't work with a HBOOT > 0.80. From what I've read, there is a way to downgrade your HBOOT to 0.80 but with very mixed success rates.
hi all.
well im expecting to get abuse and called every kind of noob under the sun, BUT
im prepared to take it as normally someone will eventually give me the answer.
Currently i have a Desire - running Stock Froyo 2.2
i have rooted my desire using Revoked 3, so i have clockwork installed.
i have downloaded a few diffrent roms, but im getting confused with the instructions on exactly what to do to flash the actual rom on the phone.
Many people are saying about using diffrent tools/mods/processes, hench why i thought id come to the experts..
im intending on trying 4-5 diffrent ones to find the one i prefer, hench im looking for a general "do this, this, and this, reboot, bingo"
i have downloaded;
DeFroST_4.3
LeeDrOid_V2.1_A2SD
SuperFinal
(looking for OpenDesire, but cant find a dam download link which works)
i have used the nexus one (pure 2.2) and i really liked it hench looking for something fairly close to that.
can anyone help me please.
I think you need to read more pal, but essentialy the steps are:
1 reboot into recovery
2 wipe all your data (factory reset)
3 use the install from zip file option
4 enjoy your new ROM
however I would recommend you reading and studying the methods cause there's always a chance of bricking your phone

Rom Manager

ROM Manager, as it connects directly into Clockwork and enables everything that way, that should make flashing sooooooo much easier.

Hi, I new the trying to root my htc evo 4g i just got from sprint. I`m looking at using unrEVOked 3.21 since i have a macbook pro. I was just wondering if it will delete anything off my phone, it says no data wiping. And what does full nand unlock do? Also, It says it flashes a custom recovery rom too, will this change the operating system thats on it now or just the recovery & will the phone stay like it is now until i flash a custom rom to it? Thanx for the help, I`ve been hacking iphones since they came out & now I`m switching to the evo
It will not erase anything or change the ROM that's on there. Your phone will be exactly the same, except it will be rooted.
You need full nand unlock to be able to do most things, so this is a good thing.
Custom recovery is where you go to make backups, and flash ROMs/Kernels/Mods. It's completely separate from the ROM.
Edit: Welcome! Glad you got rid of that icrap . Had an iphone 4 for a few weeks. Nice phones, but no comparison.
thanx for the help, I`m gonna try to root it later on. It should work since i have the newset software i hope? android 2.2, baseband 2.15.00.11.19, kernel 2.6.32.17-gee557fd, build 3.70.651.1, PRI 1.90_003, PRL 60677.I have alot to learn. LOL Yeah, I love the evo, its way nicer than the iphone 4, i cant quit playing with it. just wish u could get the paid apps for free too. I can`t wait for the evo 3d

hahaha sorry. i meant 'roll' s-off like, 'thats how i roll'. meant it in that context. s-off is security-off. it unlocks the nand, bootloader whatever. this allows you to flash radios, pri's, boot animations, etc.

Nothing is 100% safe. But the Wiki method of rooting is the safest there is, and the risk is low. Just read as much as you can before you start, and follow the instructions very carefully, and you will be fine.

As how to install Sense on the phone, the best way is probably to flash the Virtuous custom ROM after you root. Not only one of the more recent Sense Froyo builds (1.85), but also will keep you rooted, comes overclocked by default, and has some cool extra features and optimizations. Installing Virtuous is a snap. After you're rooted, install ROM Manager, flash clockworkmod and make a nandroid backup of your current ROM, then use ROM Manager to flash Virtuous.

Not only it will prevent him from Flashing Stock DZ onto G2, he might even end up bricking his phone.
I have G2, rooted, used Virtuous on it with Sense, it was fantastic, but I have never been a fan of Sense ROMs in general, so went back to CyanogenMod and enjoying Gingerbread right now.
Rooting is not rocket science but it does require you to fully understand the method, if you don't, ask questions, read forums and get yourself familiar with before trying and end up bricking your phone.
How to one by one :
First thing you need is Root Access
Try this link
http://wiki.cyanogenmod.com/index.php?title=TMobile_G2:_Rooting
Or alternatively you can try the links provided by redpoint73.
Once Rooted, first thing you want to do is install ROM Manager from market, search for ROM Manager, check this link if you can't find what you are looking for.
https://market.android.com/details?id=com.koushikdutta.rommanager&feature=search_result
Once installed, open the app, give Root access to the application and Install ClockWorkMod Recovery on your phone(CMW).
Once this is installed you are almost there, between your rooted and cmw installed phone and you flash any sense rom, is to make Nandroid Backup.
Here is how to make a backup of your current/stock ROM. Boot into recovery mod, go to Advanced option, click Backup and sit back and wait for about 5 minutes, system will do a backup of your phone to the SD card. Once done, you are pretty safe, incase if you screw up something, you can go back to original and get your phone back alive.
Once you did the backup, now you can download any ROM you want, flash anything you want and enjoy. One thing you would want to know is S-On and S-Off. S-On means there is a check for the Stock ROM, if you try installing anything with is not made for your career, you will screw up your phone. Once S-Off, you can flash anything and everything available for your phone. Which means, you can install CyanogenMod, you can keep Stock, Install DZ ROM, any ROM you want.
There is a way to Check if your phone gained S-Off or not, it is explained in the link I gave you above.
That's it!!!
Happy Flashing!!!
Edit : Oh by the way, you want to check out some videos available which will help you gain Root access and do other stuff with your phone at this link

I believe being S-On (and/or not having SuperCID) will prevent him from flashing the stock DZ RUU onto the G2. I'm sure somebody here can confirm that.

He is completely right! Another way this can be done is through ROM Manager and flashing a Virtous ROM with enhancements. This ROM is no different from the stock and is completely stable and I can guarantee your safety. But I do still advise setting up a back up just in case you start to not like it. I know I did because, it is to simple but it does look good! Lol
One thing you should worry about is your CID. If your CID isn't one of the standard HTC Vision ones then it wont let you do it unless you've rooted the phone with SuperCID.
