[Q] Just a Question. . . (SOLVED) - Defy General

Can I downgrade from the official T-Mobile US 2.2 (34.4.9) to the official 2.1 (6.36.0)?

no, you can not, there are 2 elements in the new bootloader that prevent downgrading

i think you need use restore other's backup

Yes you can by flashing the the sbf for 2.1

Awesome Now I can flash with confidence!

It absolutely works!! I've done it more times than I can count... In fact you can downgrade back to 3.6.360 coming from any rom currently available to date.. Well I have never tried coming back from the new Arabic 2.2 Rom that just dropped (3.4.3-20) but I've flashed back from 3.4.3-11

I flashed successfully

Which sbf did you use? If you check for update is the 2.2 update there?

Picked up a g2 with android 2.3, unable to downgrade

This phone was not rooted, htc upgraded it to 2.3 and I'm getting errors downgrading, and ideas?
Sent from my T-Mobile G2 using XDA App
You need to provide more details...
1. By what means did you get it?
2. Did you root the phone?
3. Do you have a warranty?
4. What kind of error?
5. A screenshot perhaps?
Explain your problem more in detail, also I think this is the wrong section for that. check the general questions section.
cant downgrade 2.3, you are stuck on there till there is a new root for it sorry
You tried using a gold card to downgrade it?
When did T-Mobile send the upgrade
Also I think this is in the wrong section

Wrong section. You should either be posting in the QA section, or one of the root threads with the error you get.
When was gb released? My sister hasn't gotten it yet.

but is the OTA for gingerbread being pushed to those who arent rooted yet?
Got the phone on craigs list the previous owner sent it in for repair for hinge issue and got it back with 2.3. The phone isn't rooted. I like 2.3 but prefer my freedom. I'm at work and can't recall the error but I can push the files with adb but get the error when I run adb shell p.... I did the goldcard. I'm thinking I'm stuck, but ill give it another shot later

Meanwhile, those of us with root have had Gingerbread for a couple months now. If it's not available OTA, it's not officially available.

yup i have it too as well not a big deal, no its not OFFICIAILY OUT, but the Official stock rom is here to flash for those that want to try, this is the latest one and most likely gonna be pushed out.
as my sig shows i have one g2 rooted running cm7 and my other on stock gingerbread no root or s-off
as well this Leaked officail rom was able to fix those that had soft bricks and could not unbrick
and everyone knows to do that the roms have to be signed officialy by htc/tmobile

I don't see any harm in taking the update. Afaik it is just a radio update which can be reversed by running the ruu back to an older version. Try it and let us know your results.
Sent from my One V using xda app-developers app
It brings me to the cwm recovery menu and when I locate the update -sdcard/downloads/update that's where it is, it says this software could render your phone incompatible but it's an ota update
So it should work. I'm just scared to brick this phone I just got it two days ago so I could return and say it's not working I want another but I got it on sale and I don't know if they would do that or if I have to pay the extra 100$ which I can't do. Do if it doesn't start up what could I do to fix it? Like when you flash you have to fastboot a boot.zip file right? How do I do that? I'm still on stock obviously and I have a backup of my current status and completely brand new stock, thanks guys

To install the OTA update, you'll need to restore the stock recovery, stock kernel, and most likely relock your bootloader. If you are using Virgin Mobile, be warned, the OTA is not compatible with any roms or kernels available now. If you try to install any custom roms or kernels, you will be stuck in a bootloop and will have to RUU back the older version to install them.

Ok thank you I am using virgin mobile but I like the stock phone I feel changing roms is too much work and I feel as if I won't like them plus I need a computer 24/7 and also I don't feel comfortable with switching back and forth all the time if I don't like anything. Mods can delete this if they'd like I got my answer thank you guys

If you updated the phone, the new radio has a problem with the kernels used by the custom roms that are being released here and the phone would constantly reboot itself when a different kernel/rom is used. You can still unlock your bootloader and root the phone, but you will be stuck with the stock rom/kernel.
You might want to downgrade the radio first by running the official RUU.
After you downgrade the radio, you can then unlock your bootloader and root without having any kernel problems. Something about the updated radio that comes with the OTA update ruins any custom rom/kernel installation.

You don't have to worry about downgrading radio... your device is a GSM as most of us in Asia.
I do not how to downgrade. Previously was using Samsung galaxy 3 which is way simpler to flash custom rom without unlock this and that. I am just afraid brick my phone. Anyway I just downloaded an app called contacts + so far it solves my problem like a charm

[Q] Stock unrooted ROM

Hello
I was wondering if I could get a stock ROM without root. Or could I do it my self by uninstalling SU?
Thanks.
Why would you want that ?
You can unroot by removing supersu.apk from /system/app and deleting root binaries.

Thanks! I'll try it in the morning. I wanted to find how to do this because there seem to be no RUUs.
Sent from my Galaxy Nexus using xda premium
Well there are ruu's....but depends on which one you need.
Well a Australian Vodafone RUU for Jelly Bean would be nice. But I've seen that the sites have be shut down.
Sent from my Galaxy Nexus using xda premium
There is a new domain up, google for android ruu.org index. But i dont think a JB voda ruu is released/leaked. The JB ruu's are pretty rare
Yea, I've kinda noticed that. But I could probably flash a stock European ROM and unroot it using the link you gave me.
Sent from my Galaxy Nexus using xda premium
http://androidfiles.org/ruu/?dir=Endeavor this the site but its down at the moment, but its the actual one. You cant run a different ruu for your phone then the official one (no other region or wwe european one) and yes you can run a stock jb rom and unroot it but then the next the owner will not be able to update the phone
I tried that site not too long ago so its still down. If I flashed the RUU then unlocked it, would it still get updates from Vodafone?
Sent from my Galaxy Nexus using xda premium
I was on it last night so it will come back up i guess......to be able to update the phone you need :
Stock rom (out of the box stock)
Stock kernel
Stock recovery
If one of these things are messed the up the update will fail
And yes if you ran a ruu and only unlocked the bootloader it can still update ..... even with root you can still update, you loose it after the update. Only when you messedwith system apps like deleting them, removing bloatware apps from voda then the update will fail again
Alright, by unlock I meant a network unlock.
I'm guessing that after updating to JB and a new HBOOT I can't run a ICS RUU?
Sent from my Galaxy Nexus using xda premium
ow haha your right after the JB update you indeed can not run a ICS ruu anymore ! :good:
I think I'll get one of the European rooted ROMs and unroot, flash stock recovery , kernel and OEM lock!
Sent from my Galaxy Nexus using xda premium
yes thats possible....but it still wont update in the future. the updates go by CID. that is not changable....so you flash a rom for CID A and the future update will search for CID B with a different software number and at that point it will 100% fail !
I thought you can't change your CID.
Sent from my Galaxy Nexus using xda premium
That's what im saying....you can't change CIDS. but you want to run a custom rom based on a wwe rom. most of the roms are built on the european base 3.14.401.31. And not on the software number from vodaphone that is released on your phone......
Vodapaphone gets a softwareversion from HTC and they put all sorts of vodacrap in the rom (branding the phone) so basically the phone is stuck on that. The next update will also have that crap and is looking to update the old vodacrap, but now its no longer there so it won't update.
Hope i make it a bit less difficult like this
OK I don't think there will be too many updates.
