Downgrade from 2.1 to 1.5! - Hero, G2 Touch General

I know, the upgrade is not ready yet, but maybe someone knows the answer to my question:
Would it be possible to downgrade to the official 1.5 rom after I upgrade to the oficial 2.1?
Thing is, I don't know if everything will work fine. I heard there are problems with video/picture quality etc. on the sprint 2.1 rom and there might be other issues. I will of course upgrade, but I'd be happy to know that I could downgrade again.

Don't worry, Hero will never get an official 2.1 update since HTC wants us to buy HTC Legend / Desire instead.

Urm,... Possibly,... But I really wouldn't recomend it.
At the moment, when trying to downgrade from one official ROM to another we have to use a process using a "goldcard",... However this exploit may be shut down in the new updates.

Do not apply PART2 OTA 2.1 update - If you need root.

I would like to remind ppl, because many of you didn't think about...
If you will apply, 2.1 OTA update, on your 1.5, you will LOOSE ability to root. Don't be fools, and wait until you get "official" rooted 2.1, then flash it by yourself.
Please someone make it more clear if possible...
...But 2.1 official cannot be rooted, after update.
So turn off your Update check on your phone, and wait until there will be 2.1 rooted.
P.S
Looks like there is possibility to downgrade from OTA 2.1!! Omg
May I ask why HEOR upgraded to official 2.1 OTA couldn't be rooted??
It is temporary unable or permanently??
Can you substantiate this claim? Proof that the instantroot method (using the package installer's privileges) does not work on 2.1 for instance?
@iholleh
It's not possible to root at the moment, it could be quite a while before someone figures out how to root it if its already on a device, however if its looked at enough I'm sure they will do it. when its officially released it will be rooted very quickly to be flashed as a zip.
good to know...thanks for hte info!

The problem is you can't say one way or the other.. so if root is important to you then you are better off waiting.

Thx bro! I just upgraded to 2.1 OTA and trying to downgrade to 1.5, failed however...
Wait for good news
I think we need to make clear. What to do if.
I installed the first package (First OTA, PART 1, Youtube App update)?
Like I heard in develop, if I installed part 1 update, this stupid youtube update, i need downgrade.
I don't really understand why, and how to do that. I think many of noobs like me are interested, what to do now.
I have promted by my phone that 2.1 update is realeased, and I did not downlnoad it, because I would like to have root, to install in a future Android 2.2, etc.
If so, and i have Firmware build number 2.73.405.93, or 2.73.405.94, or 2.73.405.95. What should I do?
Please someone, write step by step action guide.
(Downgrade, root, install rooted 2.1?) If so, how exactly?
I also understand that, there is 100000000000 of guides out there, but IMHO we need new one for a while.
Situation with "not installed" OTA part 1 is little bit easier? Normal ROOT, and install for coocked, and rooted official 2.1?

I guess so, but how likely is it that the hero's 2.1 firmware is different in this regard from anything else? A quick google confirmed that the InstantRoot method works on nexus one and motorola droid.
Edit: But a little longer google had me wondering if it does work on 2.1 again. Sorry, I should check more carefully. If anyone has tried it do step up.
Check out dev. section. Looks like there is way to downgrade.

What if I want to root it up to 2.2 (Froyo) that would be fine because it is like you are upgrading to newer firmware?
Hi i just have a stupid question :
i'm quite lost with all the stuffs about the 2.1 update :
i have a 1.5 stock rooted rom on my hero.
i would like to update to 2.1 but keep the root thing.
and i want not to wipe my phone
So what i undestand is :
- if i update : i'm not root anymore and won't be able to do it with the 2.1
- if i want to be 2.1+root i have to use a full rom (rooted) to have both but i have to wipe my phone.
Is that right ?
Is there or will it be a way to have an update (not wiping phone), in 2.1, and with root maintained from my 1.5 ??
Thanx for help.. i don't what to do with this ota update...
Ciao

I might be out of subject and truely I know nothing about rooting but I know by fact that downgrading from official 2.1 to official 1.5 took about 15 minutes to proceed on my unlocked Hero today..

[Q] Thinking of Rooting

Well i've been waiting and waiting and waiting and waiting.... for telus to release the official 2.1 but it seems that that's never going to happen so now I want to root my hero. Since i'm new to rooting my question is which ROM would you guys recommend, I want the one that's the same as the Sense UI 2.1 that would be on the hero if telus wasn't retarded. There are so many ROMs I can't figure out which one is which so if you guys could help it would be appreciated
You can upgrade the Telus Hero to 2.1 without rooting. I did mine the other day.
It will be the unbranded WWE 2.1 ROM

I have not seen this anywhere, do you have a link and just to clarify I have the TELUS hero does it work on this phone.
Once you've installed a recovery rom you can try all the rom's you want. You can switch between then in about 5 minutes or so, so its really easy to try out lots. My guide will allow you to gain root access and install a custom recovery. See my sig for a link.
Kk, Ive been looking more and I think that VillainRom 12 is the best for me anyway

[Q] Ultra-n00b: what ROM or firmware do I need?

Hi, all.
First timer here. Got the wife a Hero for X-mas. Notice it's slow sometimes, so thought I'd upgrade. It's on 1.5 now. I ultimately want to get on Android 2.1. However, in the phone settings info screen, there is no update option. I thought this might be due to the firmware not being up-to-date so was going to start by upgrading that. But I don't know which ROM to use.
I bought the unlocked phone in Switzerland, but it was clearly imported from the UK. I see on the HTC site there are several ROMs which are carrier specific. There seems to be a generic ROM on the bottom of the HTC page which says "ROM Upgrade for HTC Hero" with no specific carrier. This one looks to be the generic ROM, which I should use. Is that the case?
I've tried looking for a general tutorial, but they all also seem to be tied to carriers (Sprint, T-Mobile, etc).
Cheers.
Hi Bozo,
firstly do not be tempted to update your firmware to the latest one on the HTC web site, if you do that and also update to the HTC 2.1 ROM, you will not be able to ROOT your Hero without firstly downgrading again.
ROOTing your Hero will allow you to go beyond 2.1 to 2.2 ROMs, these are mostly in development at the moment but I've tried several so far and have settled on Android Version Froyd Villain1.6 (2.2.1) which has been great for several weeks with no crashes and plenty quick.
Hope this helps!
There are plenty of web guides on how to ROOT your Hero also Youtube videos.

Thanks for the reply. Is it the firmware that prevents rooting, the ROM, or both?
I've seen several of the videos on rooting. But again, they often reference a specific carrier model Hero, mostly Sprint.
I'd check out this post. Ignore the stuff about updating RADIO though.

Personally I use Cyanogen 6.1.0 with FlyKernel 12a (applying the FlyKernel CM fix first). Then custom tweaking the Cyanogen setup. If you were UK I'd offer to do it for you

I was able to root my phone after upgrading to the official 2.1 ROM.
There are many great ROMs to choose from; CM6.1, Froyo 2.2.1 Final (by Elelinux), FroydVillain 1.7.0 My personal preference would be Elelinux's one.
Just go for Feeyo's 2.3 1.0.1 best one ever.

I second that!
I am a flash-aholic and have tried nearly all the 2.3 roms. By far the best is cronos 1.0.1 It is uber fast (faster than any 2.1 I have tried) and has a brilliant forum community, with the dev responding quickly to any bugs.
Have fun!
Why shouldn't he update to the official 2.1 Rom? It is said to be rootable with Universalandroot! (see http://blog.23corner.com/2010/08/30/universal-androot-1-6-2-beta-5/#more-407) So getting the official 2.1 would also be a reasonable step towards more speed!
And I don't see a downside of doing so...
Thanks for all the info guys.
Is it possible to brick a Hero when attempting to root it?

Will htc at least release 2.3 gingerbread for wildfire?

I am just curious will htc release 2.3 android for wildfire??? Anyone know???
Best regards
Sent from my HTC Wildfire using XDA App
Unlikely. But, this has officially neither been confirmed nor denied. Someone sent a mail to HTC, and, got a standard automated reply "We will notify you if we are providing 2.3 for Wildfire... bla bla bla"
Anyhow, as I said previously, in my personal opinion, it is unlikely. More so now, because the Wildfire S is out.
Good point there... I mean it is kind of strange that we have custom roms for wildfire based on gingerbread that work quite fine,and then we dont have original rom with gingerbread... and then stupidest move of all is to lock bootloader and all that malarky that makes froyo unrootable...
Am I right or wrong???

It's to force people to ditch their Wildfire and get their new line of phones. Simple and cold business logic.
why the hell do u need official gingerbread on ur wildfire. the official froyo for wildfire updated the bootloader and implemented greater security on the bootloader, so that no one knows whether it will be rooted or not. 4months of work without any result.
i dont want official gingerbread on my device. and i dont want any further security on my bootloader. need someone to root my wildfire.
the answer to ur question is wildfire is not getting any official gingerbread. the 3 network in UK has already confirmed that.
the reason is simple. wildfire s is releasing this may, which decreases the htc support to the original wildfire.

Hero wasn't a budget device but the Wildfire is.
HTC Tattoo for an example is still on 1.6.
Also HTC UK said on facebook, "Because of the capabilities of the wildfire we think its best for now to keep the wildfire on 2.2"
Which makes no sense, Gingerbread is even faster.

great news dude. it means that even u can still root ur froyo wildfire now. ur patience benefitted u. to be patient is what i learn frm u.
and where is that modified version of official froyo update. can u give me a download link of it.
i think the modified version definately has an updated radio, updated recovery image, and other updated things leaving the HBOOT unupdated. do u face any problems with this issue.
i think the modified update is OTA UPDATE zip file. and in that ota zip file, we will see firmware.zip .
the firmware .zip contains boot.img and HBOOT file
i think u replaced the boot.img and HBOOT with an older version eclair RUU. am i correct
creators of the modified version, pls let me know how u did that.
edit:
oh, sorry i got it.
so, u first had a rooted phone and then u made update with ROOTED OFFICIAL UPDATE.ZIP

No one has, because Gingerbread Sense does not boot on the Wildfire. Atleast yet.
Gingerbread is pretty light, It has the exact requirements of Froyo.
It will not run slow, there are custom roms that prove that.
HTC is just forcing you to buy a new phone.
I think I'll go Samsung next time.
From my expirence with samsung - DONT!! My tab has had no updates, is laggy (as all other galaxy s devices are) I would reccomend a higher end htc

+1 on samsung. I myself am thinking of getting a Galaxy Ace. Rooted my friend's ace yesterday - it was so easy! Just psneuter (superoneclick) is enough - and you have full system r/w access. Trying to get CWM running on it now
Actually, a lot of the new SE phones are supposed to ship with unlockable bootloaders. As far as I know, anyway. Neo, Arc and Play, at least. These seem to be fairly high-end.
Just wondering whether they will back out soon like they did with PS3's OtherOS option.

needed a htc hero 2.1 update-2 rom

Hello everyone,
since I have a custom bootloader I cannot receive any official OTA updates, however I'd be glad if someone could upload/link an image of the update-2 ROM of the htc hero. (which includes a youtube app and twitter update). I have already looked for it on the internet with no success.

This rom from Elelinux is almost stock, more stock rom you will not find here with the latest hero updates.

But this is update1 ROM. Has update2 ever been released for Hero?

I am pretty sure, because on one hand with the update1 rom it asks if i want to upgrade(however i cannot with custom bootloader) and htc also announced it. It should have a twitter and a youtube app fix.
i think update 2 was fr sprint users?
n besides it was never released wit update2
two versions of 2.1 update1 were released by sprint despite being different releases both were called update1 :S
speaking of YouTube. its really annoying getting the cannot play video notification. is there any fix for this? or any rom which the YouTube app flawlessly works on.

what twitter update? peep in update1 works perfectly. and the twitter app from the market is far better than peep anyhow. peep is only a requirement in htc roms that have friendstream, which isn't in any official hero roms, only in ports from other phones.

i found this on internet, but it's Southeast Asia version(well, it Singapore OTA release and my country is next to it; Malaysia). i dunno if u can flash this into your hero but it's worth to take a look. (I'm not responsible for whatever happens to your hero or you) Here is the link for the webpage. i still doubt whether it comes with a new locked bootloader or not. so, have fun trying(or just ask someone here to hack/mod it for us)
