i've done the same...
and i've seen everywhere that no one should upgrade to 2.1 because it won't be able to root...
help...

you cant, thats why everyone says not to upgrade to 2.1

damn it...that was freakin stupid...i've read it and afterwards i completely forgot...
i've done it because since i'm in portugal, and the european gsm version didn't come out yet i've flashed with the taiwan version. since it's the bootlader issue that is preventing me from downgrading, i think i will still be able to install de gsm 2.1 european version correct? the bootloader is the same for sure right?
tks for the reply

hey, i've found this in other forum, can it be used for our gsm hero with official 2.1?

3UK will lock the Hero down.

Hi
I have rooted my 3UK HTC hero and running Hero21 community 1.7.
If the Hero gets an official upgrade to 2.1 then if I upgrade, 3UK will lock the Hero down.
I want the best of both worlds, I want to have the latest upgrade, but I don’t what the network provider
To lock it down.
Any help!
Hywel
What you mean exactly 3 will lock it down? I am also on 3 and are curious on what you mean.
official 3UK update
If you use the official 3UK update (on the HTC web site) you cannot root the phone with 3UK update 1.5
I can’t ... do you know different?
i think the official 2.1 will not allow the phone to be rooted anyway? So dont update if you want root until 2.1 is hacked
just dont update to the official 2.1 version....just wait for someone to come up with a custom 2.1 rom with htc hero driver and all....shouldnt take more than a day for dev to make one once the official version is released

How?
I have the latest 1.5 rom for 3UK on my Hero.
I've been reading that its difficult to root. Is there any special way to do this?
I hear the goldcard method is most successful, do I need to have an unlocked phone or can I just install a different rom?
If I goldcard the phone does that mean my current rom will be rooted or that I have to install a custom rom to allow root? Are there any rooted 3UK roms around?

Use BTDAG's guide linked in my signature. it gives all the information required to be able to flash custom ROMs with root access. You do not need a specific ROM for 3UK, just use any ROM you fancy, then re-install the 3UK stuff like MSN and SKYPE separately.

Root on 2.1 Official ROM

Hi guys, I'm new to this world, to custom ROM'S and such.
I have waited for the Official ROM from HTC, but I'm rly disappointing whit the Official ROM, but now I have seen some topic saying that after installing this one, it's impossible to downgrade it and put a custom ROM. But I have seen some replays around the forum saying that is possible.
Oki, saying this, I have been searching the forum since then, about a good tutorial for this, so i can put a custom ROM on the Hero, but I cant find any, so i, making this post so that the experts can help me out
P.S. I know about the warning's and such, but nothing is impossible, it just can take some time do to it.
Thanks for the help guys
As far as i know, official 2.1 = locked phone.
Might change sometime but not yet.
Rooted mine, far preferable
Try this, about the best one i found

Sorry, no linky, forum says i'm not old enough. Or was it too few posts
Wrong, you can downgrade it. Just run the RUU update file and it will downgrade (goldcard method).
2.1 is also now rooted with the same method for root as 1.5/1.6/2.0.

???????????
where did you see this info? have you done it yourself?
I've tried to do it, with goldcard method and it didn't work.
Reply to confirm what you have stated please.
tks
I don't know or ever used the goldcard method but I can assure I did update my Hero via OTA (both of the updates) and I was able to go back to a different ROM. Simply use Amon-RA's recovery image and you can flash anything you want.
You must know something though, my Hero came with version 1.76 (back in the day) and I never installed an official update through RUU's (thus blocking the phone by installing newer SPLs). And I'm also using the unlocked SPL for the Hero posted by Paul @ MoDaCo.
The RUUs normally install a new SPL (locked probably) but as you are all aware, the 2.1 update is only available via OTA (for now at least) and doesn't install a new SPL, so there's no problem there, assuming you are using an unlocked SPL or an older one. If a new RUU is made available for 2.1, it will probably com with a new SPL, or not, who knows...

So my newly bought HTC Hero is stuck as 2.1 as of now? (Kernal 2.6.29)

That is incorrect, I did my update through an RUU (Chungwa) and therefore I'm stuck with it.

It depends...according to Nazgulled, if you did a FOTA upgrade you should be able to downgrade. If like me, you did it through RUU...you're screwed for now...
I'm assuming i'm not going to be able to since my phone came stock with 2.1 lol, oh well. Hadn't planned on rooting right away anyway. Not actually too sure what rooting would do for me...

[Q] [REQ] Orange UK 2.1 update.zip

Heya,
Im just trying to flash my old hero as im selling it, and i need it unlocking first, the unlock site has suggested i use the latest orange ROM.
Does nayone have the orange 2.1 rom in update.zip format?
If you flash back to the stock 1.5 you should get the 2.1 OTA update - there is also a thread with official RUU *it's stickied* however if you want to unlock it for all carriers you'll have to buy a code - I tried to find a free alternative but couldn't. Just went on eBay and got one for about £6.
Yeah i didnt want to use the RUU files as i didnt want to have to redo the recovery stuff.
Yah i have a code.
Never mind, guess ill just have to totally redo it.

[Q] Unlocked Xperia X10a stuck on 1.6?

I have a unlocked xperia x10a on 1.6, Ive read a few things that clash with each other about updating. I read about the flash tool that says you have to be at 2.1 to run the tool.
I want to update the android with either a custom build or even the official build it doesn't matter but im on tmobile and I dont want to loose the unlock and I've already read some material that says once its unlocked you cant update.
Is there a way to update to anything other then 1.6 without loosing the unlock or at least being able to re-unlock.
Im sorry if this has already been posted but I need a specific answer before I mess this up Ive been through like 4 phones in the last month lol.
I actually did the same thing. I bought a x10a from eBay, unlocked the phone, updated to 2.1, and put it on T-Mobile. I didn't lose the unlock when I updated.
As far as updating to 2.1 or other software, I used this guide here from agentJBM. I haven't had any problems. Hope this helps.

Chinese t328w RUU update

Hi All,
I have a chinese t328w. Can I update the phone using an RUU from a different region?
If so where can get an up to date RUU from?
When using the RUU do I need to unlock the phone?
If I use the european RUU will the phone OTA update? (live in UK)
If I use the latest RUU does it stop me installing custom roms?
Thanks in advance
info
I've been looking around and found this site
http://filesdownload.net/showthread.php?63-HTC-One-V-(RUU_PRIMOU)
that has various RUU's for the phone, could I use the
RUU_PRIMO_U_ICS_40A_H3G_UK_2.09.771.1_Radio_20.72. 30.0833U_3831.17.00.18_M_release_262651_signed.exe
on my phone? or would I end up bricking it or not work?
Or would I be best to use
RUU_PRIMO_DS_ICS_40A_HTCCN_CHS_CU_1.35.1402.1_Radi o_1.04.34D.11_20.11.30.11U_release_256137_signed.e xe
which I hope would then let me OTA to the latest version and then could I install a custom Rom to get back goggle etc stuff?
AW: Chinese t328w RUU update
ATTENTION.
Only PRIMO DS is for our Phone the other file begins with PRIMO U which is for the e HTC ONE V

Need RUU for 1.74.1402.3 chinese version
I need a RUU for this version of stock rom with radio 1.10, because I've update my phone via OTA, and that changed my radio and hboot. Now my old RUU for 1.71.1402.4 and radio 1.08 is useless for returning to stock. Also I wasn't carefull and I deleted wrongly my nandroid backup
So, if someone have or find a RUU for last chinese update please tell me where I can get it.
Or if someone have a CWM backup with this stock version I'll take that too.
download GAPPs.
please google it to get one for your device.
i am using the same device and honestly can't upload such file now.
good luck!
