Unbrand Nexus One - Nexus One Q&A, Help & Troubleshooting

Hi All,
A friend of mine has a Vodafone uk Nexus One (whilst I have a Three UK Desire lol), and I used to have a T-Mobile UK G1. One of the things you could do with that (and from experiences with friends' Heros) was create a goldcard and flash a google unbranded image.
Question is, can that be done with the Nexus one? I know how to create goldcards, but I don't see any RUU exe files anywhere. Obviously he'd like to get froyo asap and avoid the voda delays in future too.
So, he doesn't want to do custom roms, just would like to have the option of stock roms and ideally OTA updates when google give them not when voda mess about with them and eventualy release them. He doesn't want to void the warranty though, so as I understand it, fastbooting a .img file is out as he'd have to unlock the bootloader?

Hmm, unrooted nexii one are able to flash froyo without a goldcard, no idea about branded handsets. I'd suggest finding the link for frf91(latest froyo build) somewhere around these boards, chucking it on the sdcard as update.zip and hope for the best.
Maybe get the noradio .zip first, just incase it goes terribly wrong. I doubt it will though, it will either work or not flash at all, so give it a try.

We tried using a goldcard with an frf91 universal rom (i.e. the direct from google signed zip), but it failed verifiation on the phone's update system. I'm assuming RUU checked for goldcard but the standard recovery ignores goldcards
Anyone got any more suggestions?

Root the phone / unlock the bootloader, and flash whatever you want. There is no "unbranding", since Nexus isn't branded. It's just that there is no stock update that is based on your version (EPF21?), so no update will be executed.
He can try the "non-voiding-warranty" root, though it's specified to work for Froyo. If it doesn't work for him - he can try the PASSIMG.zip way of upgrading to some version that will allow root. If that fails too - oh well... Either root the usual way, unlocking bootloader, or accept the fate.

You can try the tutorial at http://bloginblack.de/2010/07/how-t...e-google-nexus-one-from-epf30-to-froyo-today/
I had same issues as my N1 was EPF30 build probably a EU one and the above tutorial helped me get all the new updates OTA, because to the best of my knowledge Froyo is not yet available OTA in EU, atleast that's what i found in google

Build EPF21B to Froyo

Does anyone know how i can get froyo on my phone with the EPF21B build? Could i change to the ERE27 build WITHOUT rooting my phone? Or flash pauls version through the stock recovery image, without voiding my warranty? Thanks for any help
same problem.
my phone is EPE54B
HELP!!!
Gotta root until Google sort it out I'm afraid.
I have ERE36B with locked bootloader. Can I just update or do I need another update file?
You're on an awkward build... I very much doubt there will be an upgrade path for you.
You will most likely need to flash a mainstream PASSIMG.ZIP (AT&T EPE54B or Vodafone EPF21B) and update from that when Google release one.

Edit: Actually, maybe you should listen to him. After clarification it seems that there were un-original roms out in the wild that didn't need an unlocked bootloader. If you updated to that ROM yourself, even without unlocking then you may not see an upgrade at all.
Old post below for continuity's sake.
--------
Don't listen to him. It seems he is telling you that you will need to unlock to upgrade. If you aren't going to unlock yet, just wait, there will be an OTA update for you too, you just have to wait for Google to send it out.
Google will not force you to unlock your phone.
Is there a way to go back to ere27 so i can update now, without unocking?
Dont mind if i have to do a factory reset or something like that

EPF21B is the official euro shipping ROM.
You can't change it back to ERE27 without unlocking the phone, period.
If you don't want to unlock, you'll have to wait until Google issues the OTA for the official euro phones.

Thanks for that completely incorrect post.
I am not telling you to unlock, both can be flashed in the same way you flashed ERE36B as they are official released images.
As ERE36B is a release that shouldn't be out in the field, I doubt an update will be made for it.
So, since I am not on Vodafone or AT&T, what should I update to? AT&T EPE54B or Vodafone EPF21B?
There has to be a way to restore the phone to factory state and factory ROM?

Sorry about that, it seemed to me that you were telling him he would never get an update without unlocking. But he did mention that he was still locked and had that release. I don't know how he got that one, but if he is truly locked wouldn't it make sense that Google knows of the phones out there with that version?
I still don't think it would make sense for Google to not give those phones an update, and to force them to unlock to upgrade.
Am I missing something important here that's really messing up my understanding?

Except that the factory ROM is different from one to another.
Tmobile factory ROM : ERD79 (which can then be updated to ERE27).
ATT factory ROM : not sure but the one before EPE54B
Europe factory ROM : EPF21B.

I think so.
There are certain ROMs that were leaked, these can be installed without unlocking the bootloader as they are release signed. No phone sent out by Google came with ERE36B, you had to install it yourself. There is also no way back to stock ERE27 without unlocking the bootloader.
My reckoning is that as this particluar ROM isn't meant to be in use by the public an upgrade path is unlikely, hence the advice to flash to a 'legitimate' release image (no unlock necessary) which will definitely be upgradable.

Thanks for explaining. I'll go edit my original post.
Thanks Rusty. What rom should i update to then? Is there another rom i can downgrade from, or is it generally impossible to go to an older rom with locked bootloader?
Can't go older unfortunately, else it would be a no-brainer.
As for which one, I doubt it matters, but I would expect EPE54B to be the next updated.
cant you just flash pauls prerooted version?

Doesn't work, cancels installation when it doesn't find the right signature.
yeh, tried that, Wont work with locked bootloader. Tried all ERE27 images, renamed to either passimg.zip or update.zip, and same for all frf50.. Only one thing left to do i guess, and that is wait.
Having the Same Problem,
Hi, I have a Nexus One from Vodafone, and have unlocked it, however, I still can't get it to update to Froyo FRF50 so I can then further upgrade it, I am currently on build EPF21B which I think Vodafone have mucked around with, because I have just updated a Friends Nexus Manually with the same file not problems, mine keeps coming up with, first:
Froyo+E:Can't open /cache/recovery/command
Then fails on this:
E:failed to verify whole-file signature
Can any of you kind people out there confirm that there is something slightly odd about the stock Vodafone ROM,
Thanks for your time in this matter, I assure you that it is deeply appreciated
Kind Regards - Ashe

[Q] Vodafone UK Nexus One to Stock Nexus One

Hi all,
Apologies if this has been answered elsewhere, I checked the FAQ and a forum search and found references that this could be done but no real instructions.
My friend has a Vodafone UK Nexus One and as you probably know when Google release an OTA it's about a billion years (or at least it seems) before it's rolled out to him as it is my understanding that Vodafone have their own special build. Therefore I'm wondering if there's any way of flashing a stock ROM onto his Nexus One (probably after unlocking the bootloader) so he can get future OTA upgrades when everyone else does?
Any pointers gratefully accepted
- echo
You can unlock the bootloader if you want, or not.
If you unlock the bootloader, download the FRG83 system image from http://developer.htc.com and use fastboot to flash over the system and boot images
If you don't want to unlock it, then use SuperOneClick to gain root, install ROM Manager and use that to flash a custom recovery and boot into it. From there you can flash the stock but with root .zip from here: http://forum.xda-developers.com/showthread.php?t=927935
Thanks Rusty, that seems to answer it! Now I've just got to convince my friend that flashing like this isn't actually that difficult and dangerous
As you're not touching the radio, it's not dangerous at all. Worst case scenario is you lose your data, so take a backup first to be safe.

[Q] Flashing a clean stock ROM on US T-Mobile HD7

I want to flash a clean stock ROM on my T-Mobile HD7 and I need to know which one to go for ?
the leaked Nodo ROM or the one posted by Ansar.
(In the Bootloader it says 'Security Unlocked' on the top of the phone)
Is the Goldcard method the only way and I want to know after I flash this ROM would it be updateable in future via Zune ?
Also where can I find the tutorials where I can learn more about this ?
Doing a search on the forums would yield directions and information on everything you've asked.
How to Flash a new ROM: http://forum.xda-developers.com/showthread.php?t=876451
As for stock ROMs, the European ROMs (unbranded ones) from HTC, would be as stock as you can get. This would come stock with only HTC apps installed, which of course, can be easily removed. This would be the NoDo one posted. You aren't going to find a true stock app, since there are none available.
The branded T-Mobile ROMs of course, come with some T-Mobile apps (that can be easily removed), and very little customization. Most important, they include preset configuration settings for T-Mobile services such as data connectivity (though this can be configured to any HTC phone with the HTC Connection Setup app), and most importantly, the latest software radios for phone use in the United States.
If you choose a device with radios outside the USA or made for a different network, you may notice varied battery life, call reception and quality, and varied data throughput.
Because you say your device is security unlocked, you should have no trouble installing a ROM for the HD7 from any region, without goldcard. I think.
original t-mobile rom for hd7
i have htc hd7 changed my rom to HD7_TMOUS_2.20.841.02_Radio_5.65.09.11a_22.44.50.1 5_NoDo, by ansar and tried to do chevronwp7 and i think i should have done chevron first before the rom. i dont know if there is a way to unlock my phone with chevron with the nodo rom already installed but thinking i should revert back to original rom then chevron it but where can i get that rom since i had t-mobile. or is there a way for me to unlock with chevronwp7 even with the installed TMOUS_2.20.841.02_Radio_5.65.09.11a_22.44.50.1 5_NoDo, by ansar (no worries i figured it out , no need for reply)

Freeing Myself from Carrier Updates - HD7

Greetings All,
Just bought a HD7 from Telstra in Australia and I have a simple question regarding the ROM currently on it in regards to receiving updates on the device.
What I am really after is the ability to free myself from Telstra in an official way.
I'd like a Vanilla ROM for my HD7 that will still allow me to receive updates from Microsoft and/or HTC as they are released, cutting out the 'Approval Time' set by Telstra. (Telstra is one of two carriers worldwide that still hasn't released NoDo for their network - I'm scared to even ask about the HTC Specific update released just after NoDo)
Is what I'm asking to do impossible?
I can see the ROM available here:
http://forum.xda-developers.com/showthread.php?t=993186
It looks official enough, but I'd like confirmation that this ROM will still allow me to receive updates as I've heard that people hacking ROMS/Updates onto their devices won’t be receiving future updates.
A secondary request would be help unlocking of said ROM so that I can tinker with the registry, side load apps ect, but at the moment I'd just like the ability to receive updates as they are released.
Thanks in advance for your help.
Estens.

Frist: Gratz to your HD7!
Depending on your country laws, a modification of the preinstalled rom is not legal or at least voids your warranty. (thankfully in germany its only the latter, which makes no effect bevause you can flash back to an operator ROM for warranty reasons).

It is possible to flash any compatible rom (HD7 ROM) on your device. See this thread for a howto. The other way is that ansar provides a hacked rom that you can update without goldcard. (See the threads of him in the dev Froums). But keep in mind that they are modified by ansar and therefore not really official. (I use one of them on my phone atm, without any problems)

This rom is a telstra rom with OS Verion 7389. The official OS verion is 7390. So if you flash this one, you still will get an update via zune (the 7390 one). I did not see any differencec between 7389 and 7390.

It was possible to force a NoDo Update via chevron (that has nothing to do with dev-unlock or flashing a rom on you rdevice). If you do this (force the nodo update via chevron) you possibly won't get any further updates.

Huh? I thought Ansar's ROMs were just various branded/unbranded ROMs? Pretty sure you can't install a truly modified ROM with a locked bootloader, right? Some people have security unlocked phones, and can thus flash whatever they want. In my case, though, Ansar's TMOUS ROM system image has the exact same md5 as Football's stock...therefore, I'm assuming it still has MS signatures intact. Flashing anything without a signature fails at 0% on my phone.
I was under the impression that Ansar's unbranded ROMs take advantage of the fact that certain branded phones (O2 for example?) simply allow flashing of unbranded ROMs (or other still signed bootloaders, which allow flashing of unbranded ROMs)? Is this anywhere near correct?

I have flashed a ROM from ansar to unbrand my HD7 from O2. But i can't flash a HTC Europe ROM (invalid vendor ID). I'm not sure if they are hacked or not but dorianmuthig stated here that they are.
Maybe ansar himself can bring in some light.
Thanks for the info ST13Hogan, your a champion.
Basically, the method to use would be to flash to the ROM I mentioned in the original post:
http://forum.xda-developers.com/showthread.php?t=993186
Then unlock the ROM using the dev-unlock tools.
Then upgrade the device to recieve NoDo.
This will still leave me at the mercy of Telstra for updates though will it not? Pretty sure they still haven't approved NoDo for their network so I'll have to wait till it gets approved before i can do this.
Thanks again.
Estens.
On a somewhat related note, i found this article and it looks rather interesting.
Can anyone confirm that this works as it may be exactly what i've been looking for.

Help with network branded firmware

Yesterday I received my one from T-Mobile UK with 1.28.61.7 on board. I am not quite a noob but I have always had devices with WWE un-branded firmwares. There is no bloatware on the device but I guess that, until s-off, I am dependant on T-Mobile to provide updates.
I am not particularly bothered about custom roms and, in the past I have usually gone with stock rooted roms so that I can go add-free and remove anything that I do not require.
Last night I lied awake thinking about the implications about what I have and I really need some informed advice about it.
If I root my device, how can I return it to stock in the future so that I can receive any ota updates that T-Mobile may eventually offer without a RUU which appear to be quite scarce?
Am I able to install custom firmwares based on higher firmwares ie. 1.29.401.12 and, if yes, will I be able to return my device back to stock without an RUU as backup?
I am most confused about the scenario which I have. I love the device apart from the 3 dot menu bar which is doing my head in and am confident in my ability to remove it but am worried about my safety net if something goes wrong. Please somebody enlighten me as to what I am and are not able to do. Thanks in advance.

You have options. Firstly S-Off is not likely to come soon if at all. HTC made it such a pig to crack, the entire year I had my One X it was never (to my knowledge) posted here how to do it. But it's not really that necessary. S-Off just adds convenience for flashing kernels in recovery at the same time as a ROM. With S-on you just have to accept that a bit more faff is required using fastboot to change a kernel.
(Side note: I have not had my device arrive yet so I am staying out of the development threads. I heard a rumour you can have a flashable kernel for this phone with S-On. Anyone know if this is true?)
Once a custom recovery is on, take a backup of your stock ROM. That way if you ever really wanted to go back for an official OTA update, you could restore the backup, flash back the stock recovery and relock the bootloader. Not sure why you'd want to go this route though.
Being on XDA and knowing how to do this stuff means you can get all the features an official update will bring you, usually months before any carrier will be providing it. You'll just be going through all this extra work to get an update that has been in the custom ROMs for ages.

Thanks for your answer. As I said, I am not quite a noob :silly:. The reason I am looking to go back to stock at a later date is that I believe (rightly or wrongly you tell me) that to update firmware in it's entirety, it is necessary to use an official update from the provider.
If I back up my official stock rom after I root, are you absolutely sure that when restoring this backup, I will be able to receive official ota updates? It is not that I don't believe you, just want to be 100% sure.
Edit Perhaps we are more likely to get s-off now that we are on Quallcom not Tegra?
S-off together with super cid would give us the ability to use any RUU for this device which gives us an excellent safety net.

It's ok. It's always best to be sure before attempting something!
You will not loose out on anything by not using an official update. All it will be is the stock firmware with T-Mobile's add touches. More often than improvements to the stock firmware, carries tend to restrict the features of a ROM and add bloatware (like game demos you can't uninstall) because they have made a deal with a game developer to make some money forcing them upon you.
Even without a nandroid backup you'll still be able to download and flash the stock firmware somewhere here. Basically anything you do to your phone you will be able to undo if you so choose. The only exception to this is that if you re-lock your bootloader, HTC will still be able to tell that it was at some point unlocked if you wanted a warranty return.
Yeah, as long as the stock bootloader is available, you just need to flash it after restoring the backup, and the updates should arrive.
The firmware might be flashable without the RUU or OTA, it was on the One X, but it was necessary to relock the bootloader.
I say go for it, mike1986 has the stock ROM in the dev section as well as his stock like improved ROM.
