G1 to Dev Phone 1

All the guides I've found thus far that have described how to root your phone and flash to a new ROM have required using a modified ROM. Is it possible to turn a G1 into a Dev Phone 1 without the use of a hacked ROM?
If I understand the guides correctly, you need to flash back to RC29 to gain a root console, then you need to replace your recovery partition with one that will take ROMs signed with different keys, then you need to replace the bootloader, and finally you neeed to flash from a modified ROM.
Would it be possible to instead replace the bootloader, recovery partition, and ROM with their stock Dev Phone counterparts, thus essentially turning my G1 into a stock Dev Phone 1? The Dev Phone 1 has root access enabled, so wouldn't I enjoy all the benefits of the hacked ROMs?
Sorry if this has been answered elsewhere, but the guides seem to focus on modified ROMs and a search revealed nothing.

You can downgrade and root, after that install official ADP 1.5 and eSPL but this doesn't really make sense, grab JF's Cupcake ADP 1.5, hSPL and you will have more fun.
The recovery system > original recovery, more options, real backup. So is hSPL > eSPL.

In this thread it says I have to replace the recovery partition with a modified one so that the phone will accept images that have been signed with different keys.
Will the recovery partition already on my phone accept ADP images, allowing me to skip this step and only deal with the SPL and an ADP image?

hSPL only gives you the ability to write non-matching NBH files. With eSPL or hSPL, you won't be using NBH files anyways, so this doesn't matter. Might as well use the stock eSPL. And yes, you can certainly write the ADP1 image once the eSPL is installed, or you can write any of the custom images... I wouldn't use the word "hacked", since those based on the official ADP1 1.5 image really aren't hacked, they're just customized. And of course, once the eSPL is written, you can switch between system images at will without any kind of crazy hacking procedure to do so -- that's what eSPL is made for.

Alright, let's take this a step further...
I am trying to identify the exact set of files that determine ADP1 vs. G1. I flashed the JF ADP1.5 and ADPCP2.0. The later was identifying itself on the phone as T-Mobile G1, despite the file name. I returned to JF, but used the boot from ADPCP2.0 and did manage to get a lot of the speed in it, as it is much faster. I still want the whole file system, though, but I need to be on an ADP version. Before you go on about su and root and stuff... I have it. But programs such as Spotter remain free if you are ADP branded. So the question is what do I need to keep to keep ADP?

Thats easy. The file that identifies to the OS if its a G1 or ADP1 is /system/build.prop. Note that you can customize this file however you wish.
The main *real* difference between the ADP1 and the G1 that gives the ADP1 infinitely more power than the G1 is the bootloader. With the engineering bootloader, you can do anything.

Xv6800 spl-1.20.olipro OS? Radio? ??

Hi,
First post for me.
I am trying to use an xv6800 given to me.
Problem is, the device will not boot into the OS.
The White Verizon screnn comes up, and at the bottome it says:
---------------
M09 No Radio
B03
D 2.17
---------------
So, I have done a bunch of reading and searching. I have gone through tons of info on the following pages:
HTC_Titan
TitanFaq
TitanStockHome
TitanOtherHome
forum.xda-developers.com/showthread.php?t=392133
I can get to the Tri-color screen (bootloader mode)
It says:
---------------
TITA100
SPL-1.20.Olipro
Serial
---------------
I would post pictures, but I am not allowed yet?
Anyway, from what I can gather, I need to load a radio and OS for that version of the bootloader. So far, I have been unable to do so successfully.
If look at the pictures in my gallery, you will see some of the progress.
There are tons of "step-by-step" instructions around, but either I am not savvy enough, or there are pieces missing.
Any advice?

looking for any suggesstions...
I have not tried a re-locker.
According to the majority of stuff I have read so far, you need to run a re-locker while actually in WiMo.
Are there ways to re-lock or change bootloader from the stage I am at?
I have seen threads about running different .exe files while connected via usb. some say you need to be in ActiveSync (successful boot of device required) and others seem to say not to be in Activesync.
If there is a way to essentially re-lock the device via SD card, I would be especially grateful for a step-by-step with links to the files.
Thanks.
P.B.

I am currently trying to flash back to a stock ROM. So far, all the .rar files I have downloaded are executable files. When I run these, the programs want me to be booted into WiMo on the device, and running ActiveSync.
Are there any .nbh files around?

Mods can we make this a sticky to stop further irrelevant threads
Please categorize your question accordingly, Anaylize which forum to post it
Development forum is only for development of phone OS related stuff
Q- My phone is stuck and the android loading or the second screen
A- your ROM flash went wrong or some system files are missing
Remedy- Flash the ROM again or try flashing some other ROM, check your SD card if its inserted properly(If you have Linux-swap or apps 2 sd activated)
Q- I cant go past the first splash screen and i cant move into recovery or bootloader
A- Say goodbye to your phone, it is bricked.
Remedy- PM me maybe i can help you get a new phone (already got a new phone after bricking)
Q- I cant go past the first screen but can enter recovery or SPL
A- Your ROM is not flashed properly or check your SDCARD maybe its not inserted (SDCARD step only if you have apps 2 sd , linux-swap or data 2 sd)
Remedy- flash a new ROM, use nandroid and and try reformatting the ext partition
Q- My phone is slow
A- Your phone is overloaded
Remedy- Try wiping, removing some apps and increase linux swap
Q- Home screen reloads after quitting Application
A- Your RAM is not enough, phone quits Launcher or Rosie to make some RAM free
Remedy- Use or increase linux swap or try increasing swappiness
Q- Sdcard says update.zip not found
A- maybe you renamed the update.zip as update.zip.zip .If you have enabled show file extensions for know file types then rename it as update.zip and if not then rename it as update
Q- Which ROM is best for me/ Which ROM is the best for 32A/B?
A- Take some time on the forums, look at the ROMs available for your device and individually assess what works for you by reading the various issues affecting them and make a decision. If that still doesn't work out for you, hey, that's what makes XDA great, try a different one and so on, till you find one that YOU'RE happy with. It's very subjective since what my needs are could be totally different from what yours are.
Q-What will/is released, When will be released, New is released
A- Post is General Forum, leave this forum for Phone Development by Developers
Any other questions or suggestions welcome

Q- ADB doesn't find or see my device?
A- I suggest reading the Sapphire Wiki as it contains a lot of information about troubleshooting when you're stuck
Q- I have no data/ 3G connection
A-Check under settings ->wireless controls->mobile networks->access point names, If you have no APN set then add your carrier APN settings from this list here

Not 100% correct: if you can still load in fastboot mode (vol DOWN+POWER) you can still boot a recovery image and flash it on the device:
1. fastboot mode
2. fastboot boot myrecovery.img
3. (in the recovery) adb shell mount /sdcard
4. adb push myrecovery.img /sdcard/recovery.img
5. adb shell flash_image recovery /sdcard/recovery.img
myrecovery.img: whatever the file is called.

Bootloader is same as fastboot mode

Hey...
How do I know if I have a 32a/32b phone?
I've got a myTouch 3g and I just got it a month ago.
Is rooting illegal? I know it voids your warranty but do you get apps for free and stuff?

Boot your phone into fastboot mode:
Power phone off
Hold Back key and power phone on
It will bring up a screen which either says
SAPPHIRE PVT 32B SHIP S-ON G
or
SAPPHIRE PVT 32A SHIP S-ON H
There will be instructions on the screen to power the phone off so you can boot as per normal.

Yeah but charnsingh says, if we CAN'T go into recovery.. You're assuming we can
The post is a bit misleading, cos we don't expect physical damage to the device (in which case, you get to the first splash, but can't reach recovery.. i.e. your Back/Vol. down buttons don't work)

Whenever I flash a new ROM I backup my data and apps using either Backup To Root or MyBackup Pro. When I reinstall my apps it never puts the apps back into the Market under my Downloads so that if the app developers update their apps it shows that there is an update. IN fac the only apps shown are the ones I've purchased.
What do I need to do, besides reinstalling each one individually, in order to have the Market get all my apps in the Downloads the way I want them?
Thanks

can someone explain what SPL refers to?
and then i hear terms like perfected SPL, eng SPL....
ive flashed some ROMs earlier...without worrying too mmuch about this SPL business, and now with a mandatory rogers update out, people are talking about SPLs (see rogers thread)
cheers

So what is an SPL anyway? What does it do?
The SPL, or Second Program Loader, is essentially the Android bootloader. It's job is more than just loading the Android OS - it also offers several other boot options, including Recovery mode, Fastboot, and HBOOT modes, and ultimately it's the SPL that allows manipulation of the flash nand on your device. Part of the SPL's job is to ensure that the data flashed to the device is correct. Most of the current shipping SPLs (apart from the "Perfect SPL's) let us flash a complete ROM image, but don't let us flash a recovery rom or boot image as it checks the verification signature. Haykuro has modified the SPL's available to remove this check and this is what the Engineering SPL's available offer. As the SPL is so crucial to the handset though, you have to be very careful when flashing it as if it's updated incorrectly then you may be incapable of restoring it without specialised hardware and knowledge. You essentially have a very expensive brick

remap "search" button on MyTouch
I have searched the forum and only found results for the G1 or remapping the soft keyboard...
Can the search button (magnifying glass) be ramapped as hard key to the camera?
If this has been discussed and i missed it, links are appreciated.
If it's a kernel-level issue, i'm on enomther's TheOfficial 2.5.1 AOSP.
Thanks in advance
[Sorry mods if this isnt the right place to ask this, tired, at work and pretty much I was asleep at the wheel. Please move this to the appropriate subforum if need be. ]

if i download a rom using my phone can i rename it and apply it or do i need a computer. im already rooted and ive got the requirements for the rom already on my phone. i just want to know if its possible or not.

it will work without computer

ROM Development
Hi, I have been Googleing for a while now and cant find any info on how to remove my current Android keyboard from my current ROM and replace it with the Hero keyboard – does anyone have any links relating to ROM modification. I a have come across how to download the Hero keyboard and load it into your current setup but I kept on getting FCs plus I want to learn how to modify any part of a ROM not just the keyboard.
Thanks.

Does my new mytouch with the more ram and 3.5mm jack have an actuall name?
Hello, I recently purchased my first smartphone. The mytouch3g with 288 ram and 3.5mm jack. For two weeks now I have been researching about rooting and roms. Most of the info that i am reading/viewing is on the oringinal mytouch3g...does this stuff still apply to mine? Will installing a custom rom give me more ram? Obviously I am completely new to all this but I am finding all this stuff to be quite fascinating...Any help would be greatly appreciated.
Thanks

As a solution to the brick issue and not getting past the bootscreen or not beeing able to load fastboot or recovery here's a solution which I had tried on my magic after I lost all hope and it worked ..Thanks to God and google
while on the bootlogo screen stuck, insert your datacable. it will show fastboot in red color on top corner.
run the android sdk cmd from dos prompt and enter "fastboot boot recovery_image_name.img" provided you can find the appropriate recovery image for your phone.
after updating, it will restart and you will bt good to go

grankin01's root guides

So what are the difference between his two guides?
Does the TRUE way really offer anything more for the beginner rooter/android user? Such as speed/ su permissions/ and custom ability?
Thanks.

it just gives you more control over your device.
its not worth it unless you will be changing the splash screen at boot and doing other mods (like flashing stuff through fastboot)

As I am new to android and this site, what is the splash screen?
I doubt I will be doing much more then the ROM flash when I get the MT4G. But I like to learn.

The splash screen is the screen that says "T-Mobile my Touch 4G" on it. The animated boot screen is the next part, where the "My" logo is animated.

One gets you root with an engineering bootloader and security off on the bootloader
The other one (super ultimate guide) also gets you security off on the radio, which basically sim unlocks your phone.

[Q] Engineering HBOOT

Ok lets start the Q&A
First:
1) What is engineering HBOOT?
2) What benefits it brings to the mytouch 4g?
3) what is Danger SPL or something like that?
4) what benefits it brings if any?
I already search the forum but to be honest xda is by far the hardest place to find stuff even thou the answers are probably here.
People talk about it but what the hell is engineering HBOOT I did a google search and theres lots of threads saying i have this HBOOT or that one but none of those define its use or purpose.

The HBoot (engineering Screen) would be similar to the BIOS on a Windows based Computer. It is what physically loads the OS up for us to use.
As far as benefits? you can flash specific sections that compile a ROM, and or Change the Splash Image, what you see when the phone turns on.
and you do not need to worry about the Danger SPL on this phone.
SPL is the secondary program loader... it gets loaded by the IPL and then it loads the OS.
IPL : Initial Program Loader
initial hardware bootup. just like a BIOS
-borrowed from a different forum.

Thanks neidlinger for your answer now my new question would be like what if I choose not to change the HBOOT once i root the phone? besides changing the splash image is there any true benefit like saving your phone from a brick perhaps? something really useful more than eye candy?

You'll get mixed answers on that one. Personally as long as you have a working recovery image, and make sure to do things correctly bricking a phone is pretty hard to do. As far as the Engineering HBoot v. the stock one with the engineering screen you can flash different parts of the ROM.
