How do you unjailbreak the G1? Need OTA updates. - G1 Q&A, Help & Troubleshooting

I just bought a used g1 from a pawn shop and it has been jailbroken so that pinch zoom can be activated in the browser. I want it back to factory specs so that I can the 1.6 update ota. Help please...

dreaming.nbh
well i'v never unrooted my phone before. but i think all it takes is that you put the dreamng.nbh files on the root of ur sd card, then hold camera button and power. then follow on screen instructions.. it should update by itself.

Since android phones are NEVER JAILED, you really can't jail it without making significant changes to the platform and building your own system image.
If you simply want the 1.6 update, I suggest either using one of the community versions in the dev forum on this site, OR you can use the ADP1 official system image available at developer.htc.com/adp.html.

Thank you, I was going to ask how you unjailbreak something that was never jailed.
If you to going to use iPhone terminology, get an iPhone

I tried all of those methods and have surfed google to try to see how to do it but none of those things work.

Lol... That sounds comforting. I'm actually going to wait an see if any xda devs decide to mess around with this and mod their own version before I start using this as my new way to root.
Believe me it works, over at Android community .com I spent 5 hours downgradng my phone trying to get it to stock 1.5 [EPIC FAIL by the way] but I got in touch with him via Twitter and he came to the group and explained it a lot better.
What it does is it uses a security hole thats always been in the android platform to install Cyans 1.4 recovery image and from here you can flash any rom, I never got to try it but I believe and blnldy will say it works.
The .apk has been turned into an application in the market I believe its called Recovery Flasher and Besides me someone else confirmed it work.
Its really neat!

Questions
1.can I update to cupcake without having to setup my phone?(i dont have data plan)
2.Whenever I try to download something on the market, it just says 'starting download' and never starts
3.Can I develop apps with the current android sdk that will work on firmware 1.1 AND 1.5?
I do not have a data plan, and I had to go to a T-Mobile store and fight with the people there until they finally let me use a SIM card to set it up...and I do NOT want to go through that again
also, I'm a C++ programmer with 3 years experience, but no experience at all in Java...so will it be hard, or easy to start developing apps for android?
PLEASE help me with this, even if you can only answer one of the questions it will be GREATLY appreciated since this phone is more complicated than a rubiks cube!

Yes, you can update it and it won't ask for a re-avtivation, dun worry buddy !
The market stuff is crazy sometimes ! Just reboot the phone, and everything will be ok ( make sure your wifi connection is strong enough )
Since I am only a highschool's senior, I can't answer the last question ! Sorry
When you start a project using eclipse with the SDK installed correctly it will ask you 1.1, 1.5, or API.
Search the forums about activating without a dataplan there are instructions on how to do it.
You need the current sdk for cupcake, there is also a ndk for making native c apps too now, so hope you make something good
thanks for the replies.
I rebooted the phone and the downloads worked thx
do you know how to install the cupcake update? I went to setting and system updates, but it said my phone was up-to-date

Since you are on a modded rom, you cannot receive updates, pick out a new rom and go into recovery and flash it, since I am going to assume you are on an old recovery, you are gonna have to rename it to update.zip and put it on the root of your sd

You can manually install the update using the threads here, or at t-mobile.com/forums ( go the development section ). The update feature of the phone sucks badly, don't trust it
btw, u make me feel old (
I found on google that if you place update.zip on your phone and boot by pressing home+power, you can update it like that, but will that make me have to setup my phone again? I dont have a data plan, so i'll just stay with 1.1 if I have to
I haven't really started with android development yet, but I've given it a look over. I'm coming from c#.net and most of the syntax is the same, as they are both have roots in C you shouldn't have a problem there. So it's mostly just learning the platform and it's library. .net is managed though like android.
Eclipse isn't really in the same league as Visual Studio though.

if you flash a rom that is based on the adp phone (cyanogen's comes to mind)
you can skip singing into your google account until you have wifi set up.
so if i just do the update.zip trick with the cyanogen thing I wont have to sign in with google at all??!?!

99% sure about this, I've been flashing ROMs, Radio and stuffs regarding my G1 for a while. At first it was kinda scared indeed, but as long as you get through the first time, the left is as easy as eating an apple pie . Ask me and I will answer if I can
all you do is
put the update.zip on the root of your sdcard (i.e. no folders)
power down your phone and boot into recovery with home and power
(optional but may be required if your phone doesn't boot all the way up.)
wipe your phone.
flash the rom
reboot and wait for phone to boot up
choose to skip signing into google
set up your wifi
open the market and you can sign into google on wifi and be able to download apps.
OMG IT WORKED! thanks to all of you
hopefully it wont crash in the future!

Rooting ?

Soooo folks , my Baby has arrived yesterday and now i have following Question:
Anyone know how to root this shard? Same as Hero? .... I don´t think so...
Thx for Answers
how did u get it so fast. where did u buy it from?
I think rooting the Legend would be like for the Nexus One, because it's the first 2.1 OS to be rooted, anyway why would you root it if no dev made a ROM yet?
We will have certainly modded ROMs with fully working Live Wallpapers but give them a little time

Depends allways from your Provider, when is your Provider West-EU u can use Market without restriction....
If the Legend is not Rooted we can't install APK games and apps?
It's exciting to see the Legend finally released. But I'm waiting for the Desire
About the apps. I'm sure we can install any apk files on the Legend. As for the paid apps bought on the Hero, you can get the apk file from your Hero using Root Explorer. I have purchased one application and the apk file is located in /system/sd/app-private folder.
The problem here is that if the developer relases an update to the market you won't be able to update your app!!!
So I found my Apps in Hero in /data/app so i can install them to Legend... thats important for first time and later when Rooted then i will use Market...
Bootloader mode, may be helpful for anyone ....
Does Anyone has a solution for rootingthe phone and activate then Market Enabler... Here in Belgium we have the same problem...
is it possible to root it without reinstalling a new rom ?
thx
Yes, i mean it will be possible , we need to wait a bit ... i´m in contact with one dev that working already on the solution ...
Stupid question, but what does rooting does? Is it like gaining full admin rights? Also what is the market activation thing people talk about?

Rooting gives you access to functions that're normally shielded from the end-user. Yes, this means you can do more, but you should also be aware of the risks. First and foremost tampering with the software in the device will always void your warranty. Moreover if your machine somehow has vulnerabilities, and they're exploited, they'll not only have regular access but they'll have full admin access to your phone. It happened to the iPhone, which resulted in ransomware being installed on some iPhones (hacked ones where the terminal password wasn't changed by the owner upon rooting it). So it'll give you plenty of extra's, but do read up on what you're doing.
MarketEnabler is an app which allows you to set different regions for the market. Then you'll be able to download apps which might not be available in your region (developers can control in which regions they want to sell their apps, and some regions don't have paid apps yet).
I'm not worried about warranty. Besides you can always flash a official rom back right?
Checked up some more on rooting and it doesnt seem too usefull yet? Removing default apps you dont use and move the cache to SD card seems to be the most usefull at the moment. And maybe running apps from SD though that doesnt seem fail safe and google is working on that anyway right?
Sorry for the questions. I get plenty of experience with WiMo but this will be the first time I get a android phone so its kinda like having to learn things all over again
On WiMo its sooo each Just flash and find you .cab's and your good to go. About that, does android actually have some decent copy protection? or is it like wimo where you only need a .cab or the iPhone that also runs whatever you want after jailbreak?
When i look in the settings menu there's also an option accesibility only its shield of.
Does a root give me acces to this option?
I'm currently thinking of getting a Vodafone-branded Legend since it's much cheaper here in my region.
How are the chances of getting rid of the branding (it's software-only, just 2 links on the home screen and a boot animation) and to upload the original rom image to the phone? I want to have the latest updates on the phone when they're released by HTC...
Your going to need a hacked SPL to be able to change the boot image... and as this phone has just been released I'm guessing your chances are very slim at this point in time..
What i mean is to replace the complete ROM with the stock ROM from HTC.
What i've heard is that future updates will probably be released later for the branded phones, so i just want to have updates for the ROM as early as possible.
Most probably it's too early to make any assumptions here.

Well, for the Legend there aren't too much options yet, but for the Hero there's a ****storm of custom ROM's, from leaked 2.1 ROMs to AOSP (Android Open Source Project) vanilla Android builds ( means without HTC's modifications). So for me (not a developer), it's a matter of waiting 'til the device gets rooted and some custom ROMs start popping up. 'Til then: no, rooting won't do you much good .

What's the highest official ROM?

My local provider doesn't seem to have the Dream listed. The one in my possession runs 1.5 at the moment.
flashing procedure as well would be appreciated.
Official is 1.6. There should be an OTA update from your service provider. Any custom installs require root.
Do providers have the same method of supplying OTA or will I have to ask my provider?
Just download the official 1.6 rom and install it on your phone by renaming to "update.zip" and flashing it.
I can't post a link cuz I'm new, but google "official 1.6 g1" and you'll find it.
I don't know how to force an OTA.

that might not be the case, i got flamed on here once because i asked if a non rooted phone can run 1.6
what ppl didn't realize was that many providers have not created 1.6 ota, tmobile is the only that i know of (now) that has
Rogers has not i know of forsure.
Yes, 1.6 is the highest like everyone else has said. You will notice on this forum we have ROM's going all the way up to 2.1 or so.
Just my opinion and my advice, stick to 1.6. The G1 in my opinion just doesn't have the hardware to run 2.1 as well as a reliable every-day use phone should, especially as you have more and more applications and widgets, etc.

If you have robbers and have all the latest OTA's (1.5), then you've been screwed -- need JTAG to get root.
The latest HTC build (the word "official" doesn't apply to android at all) is 1.6, which you can get from developer.htc.com/adp.html -- flashing procedures includes, however, they won't work if you don't have root.
The OTA updates for each provider differ in their security keys, so an update for one provider WILL NOT work on a phone sold by someone else.
so i have to root the phone to run 1.6?

If you could simply goldcard any old build onto a robbers dream, they wouldn't be stuck at 1.5 -- instead, you need to disassemble and jtag.

Sign out of Google or Reset the phone ?

i bought a used g1 on ebay for $40 and when i click on various settings it states a gmail email address but it doesnt let me change it, only enter the previous users password. how do i delete his account? should i just reset the phone to factory default? if so how do i do that? also Wifi is available right now, if i reset the phone will the wifi become locked? i dont have a data plan just prepaid plan. thanks for you help in advance
You have to reset it first. Then You will need to setup Your own google account details. You will be able to set your own wifi settings and turn off data if Your pay as you go plan not include it. Read forums and download manuals as it can save a lot of stress and money for You. Enjoy Your google device

Choose whichever is more understandable for you
BTW, this will downgrade you to 1.0, so if you want to use newer firmware you're gonna have to root and flash a custom ROM.
I can walk you through it, if you don't know how.
that whole guide is just to enable wifi? why the hell has htc even locked out wifi???? also since your guide downgrades me to 1.00 isnt it easier for me to just install custom android firmware that gives me access to wifi,etc?

Wifi isn't accessable until after you sign into google... I just got my g1 too, but mine only cost 3 weeks of begging a friend! Without data, it's a PITA. I borrowed a friends sim card (with data) to sign in to google, and once past that, turned on wifi and switched back to my sim. Much easier if you have the option.

Yes they just want to force a data plan on you
And to install custom android firmware, then you'd need to start with 1.00
After you do the wifi thing and sign in, you go on to rooting and flashing a custom recovery. Then the rest is easy peasy. If you want to I can help you. You should install Froyobylaszlo.
im worried about bricking the device, plus on some of these guides i clicked the terminology is unclear or not explained such as "terminal", etc
I've messed with my dream so much and never bricked it

Try to follow the Cyanogen's Wiki
Here's how to setup an google account with a Wi-Fi connection:
http : // wiki . cyanogenmod . com/wiki/Google_Login_via_a_WiFi_Connection
These steps will only work if you haven't added an account yet, and you're on RC29 system software
Here you have instructions to install RC29 system software, in section "Downgrading the Firmware":
http : // wiki . cyanogenmod . com/wiki/HTC_Dream:_Rooting
If you've an GSM data plan you can just do a wipe, and then login with your data plan.
To wipe, power off your phone, turn it on while holding the "Home" button. You'll see an triangle with an "!" inside, just press Alt+L, and then Alt+w. Reboot your phone and login with your GAccount!
Complete info about all this on Cyanogen's wiki for HTC Dream:
http : // wiki . cyanogenmod . com/wiki/HTC_Dream
Just remove spaces from the links!
hey i followed your guides above and i have installed rc29 and i setupd a google account on my wifi network. im on android 1.0.
so i go to the Market in my phone and i click list all applications or games and it cant find any except solitare. where are the thousands of android apps?????
are they not available on android 1.0??? do i have to upgrade my firmware to access the full android market? is so how do i upgrade? can i upgrade normally without hacking the phone again? how did the original G1 upgrade originally? basically i dont care what firmware i have i just want to have access to the thousands of apps on android market. how do i do that? thanks in advance

1.0 doesn't have many apps
There's a way to upgrade...
Look it up.
I can't right now.
When I get to a computer ill post a link if you haven't found one by then
But I really recommend rooting and installing a custom rom...
the OTA update doesnt happen on wifi. im guessing this rc29 i installed is already a custom rom. so what is the best custom rom for the G1 right now? i dont want anything that will slow down the phone. what do you recommend? any easy guides? will this be easier than the other guides u posted? thanks
First, flash the original RC29 G1 firmware, it's a DREAIMG.NBH file that's flashed from the bootloader.
The market thing is kinda simple to solve. Don't use the categories and these things, use the "Search function" (Menu > Search on market).
Then, you have 2 options from here:
1. Flash the cupcake upgade OR...
2. Flash an alternative recovery from telnet.
I really recomend the second option, shorter and less MiBytes to download.
Then, the idea is to update the radio and from here you can install the new SPL/Radio combo for 14 MB extras on RAM, or the combo that you prefer. Till' here all the hard part is done, the thing that lefts to do is a wipe (recommended one from fastboot), and flash the rom/kernel that you prefer.
If you want step-by step guidance, you can follow this guide: http://wiki.cyanogenmod.com/wiki/HTC_Dream:_Rooting
Do all the process till' the "Flashing Radio" section (do the flash radio thing, but don't do more steps).
From here, you must decide what SPL/Radio combo you prefer, the 2708+ radio and 1.33.0013d SPL is a good combo cause it allows to the phone to use 14 MB extras on RAM. The only thing is that this SPL/Radio combo is problematic with android 2.1.x and earlier, special kernels are needed and they aren't so easy to find. But if you're planning to install android 2.2.x or later, then this SPL combo will be one of the bests.
For guidance to flash radio/spl/rom/kernel and these things after following cyanogen's wiki, you can post here. Also, there are lot of threads here in XDA that guide you to do these SPL/Radio and other things, but be really carefull with them, you can harm your phone in a irreversible way.
i dont understand most of the terms you are mentioning. i downgraded to rc29. now what is the highest level of android available for the G1 that is an Official download from tmobile or htc. how do i install it?
http://androidandme.com/2009/10/beg...the-official-t-mobile-android-1-6-on-your-g1/
is that guide correct or do you have a better easier guide?
also what is the best unofficial rom to download for the G1? android 2.2? android 4? i dont know what spl is or radio,etc, what is the easiest guide for noobs? there are so many rom threads in the forum i dont know where to start. what is hands-down without a doubt the best rom available for the G1 right now, official or unofficial and a guide for it? let me know thanks. also are there any chances or bricking the phone?

About that link, better that you don't try it. You may have serious problems with so many written commands.
I'll be putting this as simple as i can
Respecting to the ROM and SPL and Radio and all those, just a few questions to decide about it:
You'll like features as share internet via WiFi, Bluetooth, USB, install aplications from market that require newest versions of Android, block ads on web pages and aplications, transfer files via bluetooth, they're kinda good stuff to try a larger guide for you? Or you won't those functions and prefer a shorter way?
Be adviced that with the shorter way you'll suffer all the T-Mobile limitations, with the larger one you'll have tons of capabilities and posibilities.
So, decide about this.
And some questions, to recommend you a ROM that adequates to your needs...
