Doesn't really matter as far as HTC is concerned.

Flash the stock frf91 from stock images in rom manager. The non rooted version. So just don't click the two choises it gives you.

[Q] Return Nexus One to Stock

Hi all. I was trying to find a guide to return my AT&T Nexus One to fully stock. Right now I have Clockwork Mod Recovery and CM7 installed. I would like to return it back to stock recovery and stock froyo then update to gingerbread. Can someone help me or is there a guide posted somewhere to do this. I am still a newb at this so I would appreciate some clear instruction if possible. Thanks!

Thanks. Should I use fastboot method or PASSIMG? How do I know if I have AMOLED or SLCD screen?

Will this also restore the stock recovery?
Everything.
I am planning to do the same as the OP but what I would like to know is it possible to keep Clockwork Recovery while running stock Gingerbread and if so is there any advantage to this?

You would have to at least
Root the stock gingerbread for it to be any use at all.

Alright I am really lost.
It seems there are several paths to restoring my N1 from CM7 RC1 to hopefully stock Gingerbread
Fastboot Method
PASSIMG Method
And because I have ClockworkMod Recovery using the backup and restore feature?
I wouldn't mind the last one as it seems fairly simple (I have a copy of the backup on my desktop, just need to figure out where it goes, path etc...) and should restore everything to how it was pre CM7 RC1.
I am worried that because apparently the newer version of CWM Recovery doesn't work with Froyo (2.2.2 which is was I would be restoring to, then factory reset, upgrade to Gingerbread). Also the HBOOTs are different between Froyo and Gingerbread correct? Would CWM Recovery restore the older HBOOT?
Or can I simply use the PASSIMG method with a Gingerbread Stock ROM?
Thanks in advance for putting up with my n00b questions

[Q] Updating Radio - Nexus One

Hi,
I'd like to know if I must have a rooted nexus one to update my radio version.
thanks!
Depends how you do it...
Some of the official Google updates include an updated radio also, so if you can install them, you will get the radio update with them.
The biggest factor is probably which version of Android you are currently on, which radio you currently have, and which radio you want, etc...?

You do not to be rooted. Flash radios via fastboot.

Which requires an unlocked bootloader...
Sent from my Nexus One using XDA Premium App
Yes, It's not the only way but the easiest way. Not so easy if you're on gingerbread though because gingerbread root right now still under construction. You'll need to downgrade and root it. Or unlock the boot loader and flash custom rom to acquire root. You can easily flash radio via recovery. Easiest way.

Yes, I suggest you find a guide that one of your modorators has put their time into to help people like you. Please next time look a little harder and read.

Of course. Rooting is the first step to make any modifications to your phone. What stock version are you currently on?
Sent from my SGH-I897 using XDA
I can't say you need to be rooted, but it is needed for certain backup utilities like Titanium Backup. Otherwise, all you need is CWM

I suppose I misspoke. Root is not required, but is greatly helpful, and I'd suggest obtaining it first.
Sent from my glitched ICS Captivate using XDA App
I would say , root is highly recommended. But I think I seen a tutorial somewhere about flashing clockworkmod recovery on a stock unrooted captivate, or flashing a modded 3e Recovery to flash unsigned zip packages. I will try to find the link for you. But to backup all your apps and data, you will need root.

There are methods to root gingerbread, but they tend to be more involved then earlier versions of android. I correct my earlier statement that root is necessary. I'd highly suggest it if you want to back up apps etc, but it isn't required. I'd suggest downgrading to 2.1 or 2.2 and use the superoneclick utility. Supposedly this tool works on gingerbread but I haven't had any luck with it.

The easiest way is probably to flash Corn kernel, because you get the option to root in CWM. And you will have corn kernel, so it will also be easy to flash from there
Sent from my CM9 ICS i897 Captivate
If you want to flash a custom roms, flash back to stock, then flash a custom kernel via Odin, reboot to system, put the rom on root of sd card, reboot to cwm, do a nandroid backup, wipe data/factory reset, then flash zip from sd card. That's the basic of flashing. Search around in the captivate section and you will find your answers. There are so many topics about flashing roms. Most of the time the rom dev, posts detailed instructions on flashing his/hers rom from start to finish.
Almost every custom rom comes pre-rooted. No need to root once you flash the custom rom.
Also, if you want to save your contacts, you should do so before you flash back to stock, or before you flash the custom rom. If you want to backup all of your apps, then you will need to be rooted, and have titanium backup installed from the market.

[ROM] Android 4.2.2 | JDQ39 | Stock | Unrooted

This is just a flashable stock unrooted ROM for anyone wanting a copy to flash via CWM as opposed to fastboot. It was literally the JDQ39 system image dumped into the dsixda kitchen and thrown straight back out with NO changes whatsoever - it's not even deodexed! Useful if you need to use an app which can still detect root even after using a root-hider app (e.g. to watch Sky Go in the UK)
It is the 100% untouched, unmolested system image
Enjoy...

If you flash this, will you get OTA updates even when on a custom recovery?

Far as I know, OTA is dependent on the recovery. So you would still need stock recovery to pull the OTA.
Someone feel free to correct me if I'm mistaken. I came from an HTC monstrosity, and we all know how easy those are to modify.

Hmm. Though we would get "Failed" upon an ota via s3 I remember regardless of recovery it would indeed update as well as patch recovery. But I'm not saying this is the case on nexus devices as this indeed is my first.

Hey swirly ..as you approach a possible flash coming from this flash able stock zip would you mind posting any positive results if any with your performance and battery? I have heard and at times on other devices found at times this does improve somewhat by the partitions being reset or to those lines etc. Thank you.

You didn't keep a stock from first flash?. I always do. Good ole flashback unroot then delete twrp (depending if really needed as s3 wasn't) then protect root with root keeper then unroot take ota then load saved root. If this doesn't work on nexus 4 I'd love to know but worked on RAZR rezound and s3..if not I'll report in a created thread via next update. My reason is I like having that true first stock backup. Good for fresh installs of custom when reverting first. IMO lol

Just a quick question. If you flash this and then flash stock recovery, can you basically unroot by doing that? It'll be much easier (at least in my opinion) of you could just flash the rom to unroot and go back to pure stock
Sent from my Nexus 4 using Tapatalk 2
Well the truth is that if you have cwm 6+ the OTA installs with no problem and if you are root, it keeps it too! Just for your information the OTA needs system ,bootloader, radio, boot.img unmodified.
TBH I made this to help people too lazy to flash the stock factory image from Google. I'd always recommend the factory image personally
Gapps requirement
Is gapps required after flashing the ROM?

TWRP/CWM is for flashing roms, doing backups, etc. The stock recovery is mainly flashed before returning for a replacement or repairs.
