Can I safely upgrade my G1 to Android 2.1? - G1 General

I'm very new to Android (just got an HTC G1 with Android 1.6 from Craigs List) and I was wandering if there is a way to safely upgrade to Android 2.1.
I truly appreciate your help.

It's perfectly safe if you read and understand all the instructions before you do anything. If there's any part where you aren't 100% sure what you're doing and what the aim of it is, do more research before you press a single key. All the information is in the wiki here (link up top) and the wiki at cyanogenmod.com

One must realize that NOT ALL INSTRUCTIONS are correct. SOME instructions can brick your phone.
Using this is brick-proof: http://forum.xda-developers.com/showthread.php?t=717874
HOWEVER, your phone needs to be set up to work with it (the setup is safer for preparing for this than most others).
Installation of 1.33.2005 SPL aka "DEATHSPL" is the most dangerous step anyone puts in their instructions. The above link DOES NOT require 1.33.2005. It works with all SPLs, including all of the "perfectly safe" SPLs -- 0.95.x000 and 1.33.2003.

Thank you for the great responses.
I read a couple of instructions and looks like I have a lot more learning to do before I can touch anything. For example there are terms like rooting, flashing and other terms that I have no idea where to start from.
Do you know of any video that shows all the process?

And to add if you use this SPL.. and then decide that (after more reading debugging ect.) it would be easier to use dangerSPL; its a simple mater of using fastboot to flash 1.33.2005 and any future radios without the risks in most peoples instructions.
Information on 1.33.2003 is in CONFIRMED!! BRICKS: Radio and SPL + New SAFETY theory read a few pages around that post to ensure you understand what you are doing and what you want to install.
The important thing is to understand the importance of compatibility between radio->SPL->recovery if you want to flash these without (most) of the risk..
The other thing is to keep focused when flashing a bootloader (spl) and don't get side tracked, of start flashing other things since you last verified the state of your phone. If you can't do this best stick with what works now.

I absolutely DO NOT RECOMMEND videos.
The processes you need to follow are NOT CONDUCTIVE to being learned through videos and the PEOPLE who make the videos, by and large, are RETARDS.

Unfortunately there isn't a safe method to update G1 to 2.1 ROM. You will have to change SPL and propably a radio and when doing this you can brick phone. However, there is no chance to brick phone other way. You can try to flash as many ROMs as you want, you can do what you want, there is always recovery when you can just wipe and flash a new ROM.

1) while it may take more foot work you can flash a 2.1 rom without spl/radio changes
2) not safe well this depends.. is it safe to walk on a trail next to a cliff without a gaurd rail.. maybe not if you are blind but for most people it is... the problem is many people are blind in the android world.. and thus fall off the cliff.. frequently feeling they did everything correct without realizing they forgot the most important part..

Rooting Rogers HTC Dream

Hello,
Is it possible to root the HTC Dream from rogers yet? I just purchased one yesterday and I am not sure if the procedure is the same as for the T-Mobile G1.
Thanks
I too would like more information on this. Thanks in advance.
Dream...
I believe the Dream and the G1 are actually the same devices. So what you can do to one, should also apply to the other.
I am curious to try the G1 procedure, but I am wondering a few things... Biggest thing is if rogers would be using the same key to sign the updates? and second is if downgrading to rc29 would brick my phone.
I wouldn't use the DREAIMG.NBH rooting procedure on the Rogers Dream. If I recall correctly, it includes a radio image (please correct me if I'm wrong). If that's the case, you wouldn't want to try to flash the radio from the G1 to your Rogers version that uses different frequencies.
I would venture a guess that the method Haykuro used to root the Sapphire would work, and should be safe to try even if it doesn't. Go here:
http://android-dls.com/wiki/index.php?title=Magic_Rooting
I got that from a post in the Sapphire forum here on XDA Developers.
The key is to flash the recovery image with the rooted recovery image. I don't know what difference there may be between the magic and dream recovery images - you may want to grab the modified recovery image specifically for the dream and use it instead of the one on the wiki page.
Wish I had a Rogers Dream so I could try it. If any of you with this handset try it, post the result here!

I'm wondering this too. I'm not new to flashing devices etc but THIS is all new to me lol ... I found more info on This page that also explains about the radio however, I'm not sure what all applies or how things change with the Rogers phone. The more I read the more confused I get. One site said follow the link above and you wont have any problems, another said dont follow the site in order but do the radio first then flash the SPL.
Can someone please confirm the steps required to root the Rogers phone and then flash haykuro's ROgers ROM please? I just dont want to brick my device if at all possible (not that anyone really wants to brick their phones).
THanks guys!!
I am going to see if I can boot any of the recovery images without flashing them. I read in a thread thats possible....
None of the recovery images I've tried will boot on my device, Haykuro told me he's working on a solution with dream_kill to root this device.
So it can't be rooted yet?
Awwww I was hoping to put hero on

ya we must be patient.
i don't do that so well
the waiting game
I will be waiting as well. Though as soon as the US rooting procedure failed for me, I felt like Rogers had just bent me over and shoved a big rusty sand covered......you get the idea. Was it not enough to put Rogers logos all over the phone, but you had to take away our rooting ability's as well? How sad. But I like the phone too much to take it back Oh well, wait and hope for the best
All you guys (and girls) working on this, you totally rock!
Well, guess we're all in the same boat. I have been reading some of the other threads though, seems like maxawesome, has the Rogers Dream version, and had success rooting and flashing a few days ago, maybe he could share? Looks as though he is the first and possibly only to get root so far for rogers. I tried sending a pm to him, but not sure it went through. You should try, he has some posts in the "rogers rom" thread, just doesn't indicate which SPL version he ended up using.
I'm in the same boat as everyone else. Lets just hope we get to rooting our phones soon!
Just a suggestion: Perhaps you Canadians can try the goldcard method used for non-US/UK Dreams described in the following thread:
http://forum.xda-developers.com/showthread.php?t=485364
EDIT: Sorry, I forgot that the updated SPL may cause bricking when the older radio is used. Please disregard this post!
Wasn't it just the haykuro modified spl that caused bricking? Of course, there is more to the radio on this device, even if it doesn't brick it, may result in a non-functional radio (until the correct radio is put back).
Work in progress
I see haykuro is working on it here
More waiting and searching.
Any other updates on where haykuro (or anyone else working on this) is at?
i think haykuro is looking for a device but its still hard to find in USA.
hrmmm ... wonder if we can put a call out and some extremely generous Canadian can send one to him ... seriously if I had a way to get my hand on another one without having to fork out $700 I'd totally contribute a phone

Root HTC Hero

Hello all, I read all the posts about how to root HTC Hero (Poland Era G2) but I still do not know which method is the simplest. I depend mostly to BT to work normally. Could someone give me links to the topics. Because I have already lost in this. Thanks
the simplest way is pick one of them and try it, instead of looking through all of them

The fact you say you need bluetooth to work normally, in relation to rooting your device, suggests maybe a misconception on your part, so I'm writing this just in case that is true.
The method you use to root your phone won't determine what features it supports or how reliable it is. Once you root your phone, using any method you can find which works for you, you can install a custom recovery image (current AmonRa recommended).
When that's done you're then free to choose any custom gsm Hero ROM you like & that is what will determine the features & reliability of the device. It's also fairly easy to swap between ROMs so you can try several & very easy to revert to one you've already tried (& backed up via nandroid backup, a feature of the recovery image).
So it's okay to plunge in & try the various rooting methods, though obviously do follow the instructions carefully. I think theunlockr.com has some good video guides if you prefer video to the written word. Just google 'unlockr htc hero rooting'.
Argh, just realised the original post is two months old. Oh well. If you're reading do post back to say if you managed.

Noob question...what is the deal with the ROMS?

ok, totally new to the HD2 thing, and the ROM thing. i am a former blackberry guy, so i was always nuking and loading on new OS's, and i'm sure once i get the hang of this, it'll makde sense. i've seen the guide on how to do it, but what is the benefit of different ROMS? is that like a modded version of the OS to play with? can you restore all your contact/calendar info to it once your done?
sorry about the "noob-ness" of this question, but once you tell me, i'll run with it
thanks
Yes a ROM is basically a users take on what they would like the original OS to look/perform like. We also get updated packages from Microsoft thanks to some great people on these forums that keep us on the cutting edge of what's going on.
Basically, you unlock you phone and can flash ROM's whenever you want. You can always back up all your data and restore it all after a flash. You can also re-flash back to the original stock ROM your phone came with and restore the same info and never touch it again. Your prerogative.

This is if you own a T-Mobile USA version HD2!
From what I have seen, the custom Roms usually are faster and have more add-ons than the stock software does. At least in the case of Energyroms
anyone have a suggested first rom for a first time noob with a tmo hd2?
Dutty's...it's a very basic/clean ROM and it works very well...

i honestly feel stupid looking at the instructions for this, and i am a real technical guy too. is there a really really dulled down instruction set for this somewhere? like, "hold the hand of a baby" easy?

lol, I'm in the same boat! This is my first steps into the realm of WinMo. I've successfully loaded the Energy rom (pretty sweet too!) and just loaded the Kumar Rom last night. I really like the Kumar, it looks pretty close to stock and is really fast (plus I think I'm getting way better battery life with it).
The guide at the top of the page does a great job at explaining how to flash a rom imo, Except when it comes to backing up the data.
I (and you as well) would definitely benefit from a "Hand Holding" through backing up all the data and using sashimi or xda_uc to restore it.
I've tried both and I still don't quite get it. I just want to be able to restore my email accounts, my quick launch links, install the programs I want, and setup my facebook. I really wanna try Miri, it looks great! But I want to back up everything first.
Where are some good backing up step by step tutorials? So I don't skip/forget anything?
Thanks!
p.s. sorry if I hijacked your thread. I think you'll benefit from it greatly thou
I'm also gonna have to jump on the bandwagon and say I need my hand held.
I thought I was pretty technical but apparently not enough. ^^;;
Thanks for any help provided! =D
Actually found the installation process to be extremely easy. =D Just follow the instructions, the onboard menus will explain the rest.

ok, but here is my thing. i just looked at dutty's, and it doesn't look any different from the stock. am i missing something?
That's the point, it is very close to stock. The performance is much better than stock though. You'll notice the more crap people start dumping in ROM's the worse they work. That's why i suggest using one that is close to stock so you don't have to worry about trouble shooting problems.
Ryan and Joe,
The instructions are pretty easy, but its the concept that bugged me at first. Keep this in mind and maybe it'll help you:
1) Our phones have the Firmware (OS) locked out so we can't load our own custom one. Therefore, we have to flash the HSPL to allow custom firmwares (ROMS). Once you flash the HSPL, you should be good to go with trying out all the compatible ROMS.
2) When you decided on a ROM (Energy for me), download the version you want. NRG has two versions with multiple variants of those versions. (I chose 23549 Cookie). Download that. There will be two files, one is an exe.
3) Whether you are flashing your HSPL or a ROM, ActiveSync MUST SEE YOUR PHONE. If it doesn't or if you have problems, try different USB ports. I know I had issues when using a hub.
4) Your phone's data will be wiped each time you flash. There are some alternatives (like putting cabs in the UC folder or using Sashimi).
PM me if you need some hand-holding. I don't mind. Everybody needs to start somewhere.
ok, well i did the first step fairly easy. now i'll explore flashing a new rom, and see how that goes....
here goes nothin
so is there any software or tutorial on backing up the phone's data ( like contacts,messages,..etc) before flashing any ROMs?
and if there is one...then how do i use it after flashing the ROMs?
If you're just worried about contacts/calender/texts then use Microsoft Myphone. Just download the program, sign in, and sync what you want. Then after you flash you install the program, sign in, and sync your info right back.
Hit me on gtalk...school's in session. It's easier than it looks JB. I'll help you if you havin' trouble. YEEEE!!
PLEASE MAKE SURE the ROM you're flashing is compatible with the US 1024MB version of the HD2!!
Also, some radio ROMs can brick your device if you don't use the correct version, so I suggest noobs don't flash their radio versions.
Some ROMs come with a RADIO flash and some don't (most don't) so make sure you read the ROM description carefully to MAKE SURE it explicitedly says it's compatible with the U.S. version of the HD2 - and if it doesn't.. DON'T FLASH, don't take the risk.

Where to start?

I've had the HTC Hero since launch in October and I've loved it. But three things have really bothered me about it. One is the fact that they are constantly delaying the new firmware and the second is that my battery life has gotten worse and I've tried all that I can to fix it. The third thing is the lag that can happen, especially when I want to make calls, can be frustrating. So I've heard about the use of custom ROMS and I feel like finally transitioning over to them. What I want to know is what exactly I have to do in order to be able to load up a custom ROM? This might be a noobish question but the last thing I wanna do is brick my phone by making a stupid mistake.

Read the FAQ's and wikis posted at the top of the forum. Once you get passed those you should be able to ask the 'right' questions
Basic steps are:
Root phone
Install recovery image
Flash rom
The wiki has steps for those...and I seriously recommend reading through the thread of whatever ROM you choose.
And before you ask: The choice of ROM is up to you. They all have good points and bad points, so don't create a thread asking which is the best...it's pretty subjective.
Damageless' great set of instructions.
Here is an excerpt from his instructions:
I have compiled this guide from the other one posted on this forum, the discussion therein, and my own knowledge. If you have any suggestions on making it better or to correct any mistakes I may have made please let me know.
This guide is intended for Windows and includes detailed instructions. It will cover the steps necessary to root, flash the new recovery image, create a full backup. This will work with software versions 1.29.651.1 and 1.56.651.2. I am not responsible for any damage done to your phone using this guide. Root at your own risk.
I have put to together a video on YouTube for you to follow along as well.
Links are attached in the .txt file.
I have used the Fresh and Damage ROM's and they are very good. Everything does seem snappier, but I still get the phone keypad lag which is very, very troublesome and not noticeably different from the stock. Others have claim no lag, and so YMMD.
There are many neat things about the modded ROM's, but there doesn't seem to be much to be done about the phone lag. Not good, since first and foremost I expect the Hero to be a *phone*.

[Q] Noob seeking Root advice

hi,
I want to root my Desire Z as I would like to use Titanium Back Up Pro. I have checked thru the threads here. And, well, I am totally confused.
On TheRomMistress's great sticky there are 27 guides with at least 11 dealing with rooting the phone. Some of these guides refer you to other guides and these refer you to yet more guides for various reasons (updates etc).
I know a lot of the guides were initially worked out before the whole NAND lock was cleared up.
So my question is which guide should a noob follow to get root?
I love the whole android experience, love Sense and think my phone is all shiny, sparkly etc. I may want at a later stage to try out some of the other ROMs but so far I really love stock (heck, my previous phone was a windows 2003 Magician with BigStorage courtesy of XDA!!). I just want to be able to back it up.
Thanks for your help guys.
personally i used this guide:
http://forum.xda-developers.com/showthread.php?t=843014
worked well once i had reset my phone and made sure my sd card was clean. Read up on adb before you attempt though so you know what is happening at each stage, it makes the whole process easier. And if things don't work as expected you'll be able to sort it.
The method listed in the official Wiki is the one recommended by most people nowadays: http://forum.xda-developers.com/wiki/index.php?title=HTC_Vision#OTA_Updates.
It is generally considered the "safe" way to attempt root at this point. There were reports of semi-bricks caused by the permroot function in Visionary so general consensus is not to use it. For other guides (such as the one linked to earlier), if you have a typo while flashing the engineering HBOOT, you could cause a semi-brick as well (though if you follow the instructions carefully, it shouldn't be a problem).
A typo with the Wiki method shouldn't lead to a semi-brick though. It also has the added benefits of not only giving you root, but also true radio S-OFF, SuperCID, and subsidy unlock (if your phone was originally locked to a specific carrier).
That being said, as long as you read carefully and follow instructions, you should be fine following most any of the guides.
thanks guys for the answers and sorry for my delay in replying. The wife came home with a new netbook that she "needs". I do get the joy of setting up something I'll never get to use. Yay!! hmmmm
I'll read thru all this and hope to try this out over the weekend.
Again thanks guys.
Just use gfree method, its painless
Sent from my HTC Vision using XDA App
Sorry for responding so late, just wanted to say thanks again. Took me ages to get around to doing this. Work just went crazy busy Again thanks for your help guys.
