I recently bought a used captivate . The seller has advertised it as 2.1 .This will be my first android device and i have no idea what things should i do 1st .
i have the following questions:
1. if i get a device with Stock OS 2.1 ,should i directly update it to 2.2 with Kies Mini or first unlock it before upgrading to 2.2 .
Does the unlock process becomes difficult after an official 2.2 OR
The upgrade process becomes difficult after unlocking
2.since official 2.2 has been released there is no point in reading custom ROM threads .DO custom roms offer any advantage over the official 2.2?
3.Is tethering working on 2.2 ..i guess it was disabled on the lastest 2.1 update
4.HOW do i check if i got a phone with stock 2.1 and if it hasnt been flashed with custom roms and reverted back .This will be useful in troubleshooting if i get into any problems
personally a custom rom would be a better idea than stock 2.2, most custom ROMs are on 2.2.1. All preference though... I never personally liked the iphone-esque launcher of Samsung, so I tend to stay away from custom ROMs. Why would you go from a 2.2.1 version to a 2.2 filled with AT&T's bloatware.
Check phone info in settings to see what version it's on
And when you update to a new version it generally needs to be re-rooted especially if it's official.
In the Dev section you can find an Odin one-click to stock ROM
If you're on 2.1 you want to get your real official unlock code before you upgrade (once you upgrade you can't get this unlock code). Write the code down, just in case somehow the phone relocks (mine never has).
start reading. i cant STRESS that enough!!!!!
i read for 3 days before i flashed anything custom.
KNOW what you are doing so when you do mess up (we all do) you can properly explain what you screwed up...

then check out the stickies in each section of the captivate forum.

While it is easier to get the unlock code if the phone has never been flashed, it is far from impossible after.

not true. i unlocked on 2.2 last month. you just need a new version of your unlock program. or a different unlock program.
2.2 isnt new. ATT isnt the rest of the world. ATT was late. time for you ATT people to catch up to the rest of the world.
thanks for all the replies
There was a thread which said there are no workarounds for 2.2
how do i check if the seller has upgraded to 2.2 and then reverted back to stock 2.1 before selling me ? This will effect the unlocking process as there are many methods posted
What the official unlock code (is it through SGS Unlocker?)
Is the unlock code stored on phone or on SD card . i am not be getting the original SD card

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
My question is how do I root without unlocking my Bootloader? I've downloaded PAQman's Stock to FRF83 Rooted but I'm afraid of a couple of things. First, I'm already on Official FRF83 stock, Second, I don't want to unlock my phone since its only a month old? Any help would be greatly appreciated.
did you get FRF83 directly from ERE27? (or other eclair rom) I'm guessing that you had actually upgraded to FRF50 first right?
yes, did FRF50, then FRF72 then FRF83. But right after I flashed the stock FRF83, I saw another update by PAQman "from whatever to FRF83" rooted. So, would it be safe to reflash PAQman's FRF83 Rooted over stock FRF83?
You have to unlock your bootloader to root. There's an alternative way to do it with out unlocking the bootloader, but I wouldn't recommend it.
As of right now HTC is still honoring the warranty as long as you are able to put the stock rom back on your N1. http://forum.androidspin.com/showthread.php?t=2630
hi kobecamp2009,
I was wondering what are your sources were on the fact that they are honoring warranty if you can reflash stock? Everything I've read from various posts here seem to indicate that it's a crapshoot. Sometimes they will honor warranty on unlocked bootloaders, other times not.

according to an employee of Google i talked to, they will try to flash it to "original" state no matter what, sometimes they can sometimes they cannot *with an unlocked bootloader*
They'll flash to original state if possible, but then will they charge us 183$ for a repair?
I really wish Google would leak a Froyo build for our phones. I really need wifi tethering...Froyo would keep me satisfied until my warranty ran out!

no, if they could flash it without replacing the motherboard then they won't be charging.
Froyo for us should be sooner than Mid-July i'd say since Droid is getting its by Mid-July.... so... keep praying
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
Cheers
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)

First windows phone ever, skilled in android as well as older phones (think motorola seem editing, LOL) I just have no idea about this. I recently bought mine on craigslist and the guy added the nodo update like 2 days before I bought it, How did you revert to stock tmobile and chevronwp7 it? I want to sideload apps!
Hi,
Firstly apologies if this has already been answered elsewhere - I have had a look and couldn't find anything specific to my needs.
Basically, my question is...Is there a custom ROM for the HD7 which consists ONLY of Interop Unlock and no other changes from stock functionality?
I am looking to be able to use WP7 Root Tools on my HD7 but I do not want to use one of these crazy custom ROMS - no offense to the guys who put in the hard work to make 'em, it's just not what I'm looking for - I just want a stock Mango ROM, but I want it to be interop-unlocked.
Here's the progress I've made so far:
-My device is currently unbranded Europe (was previously O2UK but flashed an unbranded NoDo ROM back in the day) upgraded all the way to 8107. This means that I'm on a bootloader version > 5.10. Fortunately then, I am capable of using this method to downgrade my bootloader as I have a 401 (European) phone. I have the original unbranded NoDo ROM which I flashed when it first came out, which should have a low enough bootloader version.
-After that, I should be capable of flashing an RSPL/HSPL to my device, although I'm not sure exactly how to go about that. The instructions in this thread seem like a good place to start.
-Once that is achieved, I could theoretically grab the 7720 ROM from here, and edit it to include Interop Unlock. Then, flash it to my phone, run WP7 Root Tools, and I'm good to go! This is obviously the part I'm most likely to have issues with, I'm not exactly a ROM chef, and it doesn't look very beginner friendly
Hence my question: Is there a custom ROM already out there (presumably it would have to have Mango v1 drivers) which will be as close to stock as possible but with InteropUnlock so I can run WP7RootTools?
OR: Can I simplify these steps in any way?
Thanks for any replies... meanwhile, I'm going to continue my research!
Yeah...I'd say your on the right track. Use ansars SLSPL method for Europe devices to downgrade your SPL and using Shadows tutorial to install RSPL/HSPL. You can also get the 2nd rom needed for the SLSPL method from Shadows tutorial. The hard part is going to be adding in an unlock to the rom. I know this isn't the answer that your wanting but your best bet would be to find a custom rom that is as close to stock as possible!
Heh, thanks. I figured as much.
Well, it turns out that this needn't necessarily be as complicated as all that - I've just discovered that my student App Hub registration is still live (I could have sworn it had run out, as I was unable to dev-unlock my phone) but since updating to that latest Tango which just became available today, I am able to dev-unlock my phone again!
So, slightly different question: are dev-unlocks only possible with the most recent firmware? (Surely unlikely given the current status of firmware rollouts)
The reason I was unable to unlock my phone previously was possibly because of registry tweaks made down the line - I kept getting "error check the phone's time and date are correct" when the time and date were obviously correct.
If it is still possible to dev-unlock a device running Mango, then I can simply use ansar's SLSPL method to go straight to Mango 7720, dev-unlock, Interop-unlock, install WP7RootTools and mission accomplished
EDIT: Well, there goes that plan - while my device is currently on 401 (Europe firmware) it is not actually a 401 device (as it was previously o2UK branded) so I can't use ansar's method....time to go and find me a USB Y-cable!
