Unrooting and downgrading G2 touch - Hero, G2 Touch Q&A, Help & Troubleshooting

Hi there, just got a question that i'm hoping somebody can answer for me.
Currently i'm running a Villain 4.0 Custom Rom on my phone. I'm now thinking of selling my Hero and upgrading to the desire.
I don't want to sell the phone in it's current state (i.e rooted with custom Rom), with no disrespect to the devs behind the ROM intended as they have done an excellent job, it does have battery life issues.
My questions are that to go back to its original state i.e a T-mobile G2 Touch is it a simple case of following the unlockrs guide http://theunlockr.com/2009/10/03/how-to-unroot-the-htc-hero/??
If so once reverted back to 1.5 stock will the person buying be able upgrade to 2.1 via the official route once it is released?
one more thing, does reverting to stock 1.5 have any issues? i've heard somewhere that GPS doesn't work if done.
Thanks for your patience in reading this long post and hopefully somebody can answer.
Cheers

install one of these: http://forum.xda-developers.com/showthread.php?t=559622
and your phone will be "as first day"
I mean: ROM will be a "retail" one, radio, recovery image and SPL will be changed back to "official one"
ps: I don't think is a good idea to do this: HBOOT will changed and the next phone owner won't be able to install custom recovery, root and, ... since fastboot exploit is not anymore present. you should just install a stable SenseUI ROM that way rooting and other fun things will still be possible

install a stock generic rom, for example from here the HTC Generic 2.73.405.66 unrooted version. flash the latest radio before, this way you can make sure the gps works afterwards. then boot up the rom, check if everything works, go to recovery, wipe all, shut down the phone and put it in the box.
if you install any RUU the buyer has to go through the process of rooting again, wouldn't be nice imho.
and next time please check the subforum you are posting in, this was the wrong one...

Thanks for the replies guys
i think you're right, leaving the phone rooted would be the better option for the new buyer saving him the pain of the dreaded Gold card method.
I'll probably flash one of modacos roms. Now, since i'm only a noob on android and as i've understood from your posts, gps wont work. What do i need to do to get it to work? how do i flash different radios? is it before a rom flash or after?
@kendong2, sorry man i thought i was posting in the right forum, for future note where should i post a thread like this? Cheers.

Yeah, don't go down the process of installing an RUU.
Follow Kendong's instructions to the letter.

Reverting to 1.95 Stock ROM

Hey guys,
With this 1.95 AT&T ROM, just a question:
http://forum.xda-developers.com/showthread.php?t=439346
- I had the HARD SPL and cooked ROM before this
- I then flashed to this ROM because I wanted to go back to stock for a return.
Is that it then? Am I good? Or do I have to continue to flash the Stock SPL as listed in the HardSPL instructions for reverting to stock?
I'd really appreciate any help guys. I need to know if this ROM 100% puts me back to the way I was before starting with flashing. Or is there something else I have to do?
NOTE: I posted this in the thread for the actual ROM, but because of a lack of activity in that thread, I was afraid of not getting a response. Sorry for any inconvenience.
When I returned my Fuze, I just flashed the stock ROM and left Hard-SPL and didn't get any static. They didn't check the bootloader or anything. YMMV, so you may want to revert back to Stock SPL if you think they would check the bootloader. Personally, I would feel confident with just the stock ROM.
Those clerks don't know chit unless it has to do with the iPhone.

i having the same pro flash and no luck with the radio wish i could get the stock radio back
The stock radio is in the Radio thread. Flash that and you'll be fine. As was said however, you shouldn't even need it as i doubt they'd even check that.
Hey thanks for the replies, guys! That's great.
That will probably work for my return. But, I also have my wife's phone which I'm going to flash back to stock and I just want to make absolutely sure that EVERYTHING is back the way it was when purchased. Also, just for future reference I want to know how to get all components back to normal. Where is that stock radio thread?
Any help on that? What else am I missing?
UPDATE:
It just occurred to me that I should have written down the ROM and radio version numbers before doing the HardSPL and ROM flashes to try out some cooked ROMs.
Anyway, I've got the stock AT&T ROM on there now, but how do I know what radio came with my phone? Is there anything else I should put back on there? I know they won't check but I just want to be thorough.
Thanks!
if in the US it had to be the 1.02.25.32 radio as i dont think it came with any others initially in the US. if u go to the wiki it lists all the stock roms and radios that came with the device.
huh??
So, if I now have that radio and the Original ROM am I all back to stock settings now?
I'm confused though. Because out of the box I did the following:
1. Hard SPL (File called: RaphaelHardSPL-Unsigned_190_1_3)
2. NATF ROM 2.2
...then decided I wanted to go back and did nothing more than flash the stock ROM.
Without flashing back an SPL, how could I have still ended up with everything back to stock?

[problem] Dead T-mobile HD2?

I had Magloader and WP7 in it. As time went by I upgraded to HD7 and never looked back. It's been a while since I have touched XDA and WM6.5.
My assumption is that even with Magloader, you only have to flash your stock ROM and it'll revert back to WM.
Mine won't go on and I suspect that I flashed a Non-Tmobile compatible ROM. Can someone confirm that this is the case? Here's the ROM string: RUU_Leo_HTC_WWE_1.43.405.1_Radio_Signed_15.26.50.0 7U_2.04.50_22_2_Ship.exe
I understand completely that if I messed it up then it's messed up. I just wanna make sure there might be other solutions or something I am missing out.
-Thanks in advance!
----------------------------------
Is this a final answer? I need to know if it's bricked and nothing else can be done.
Anyone thinks a shop may be able to recover it back? It won't go on at all..

Sometimes, it´s easier than you think.
You´ve got 2 options to get rid of HSPL. One of those options would be simply described in the original thread of HSPL.exe software. If you would have checked this program a little bit, you would have noticed the very fact that you can select what SPL or HSPL you want to install.
Second, you can flash your stock ROM via SD card method, this will replace HSLP and everything else - this does not work using RUU.exe via USB.

By the looks of the radio installed (2.04.50_22_2), I would say that you did brick your T-mobile phone. Take a look at the following thread for a possible solution to unbrick your phone:
http://forum.xda-developers.com/showthread.php?t=668347
Hi thanks for the response Lavell. Would MTTY be able to do anything?
The phone doesn't turn on at all, or it seems.
I've never bricked one before so Idk if this is the way it happens.
its gone. dead. it will need JTAGging or a new mainboard.
that thread wont help, the phone wont power on, and that thread requires you can get into bootloader.
that's a really early rom you used, the tmous didnt even exist when that rom shipped.
If you want to get rid of it let me know please!!!
Hey guys, don't mean to hijack the thread but I got the same problem here.
Had WP7 but could not use 2g so I went back to MAGLDR113 and installed the file below:
RUU_Leo_HTC_WWE_1.43.405.1_Radio_Signed_15.26.50.07U_2.04.50_22_2_Ship
It went all the way to 100% but now the phone is dead. Computer makes a sound when I plug in usb but I have tried changing batteries and all but it doesn't work.
Does anyone know in Dallas or areas around how to do that JTAG thing?
There is no proper documentation on how to go back to stock 6.5 Windows or at least I could not find one

At its most basic, its the same for ALL hd2's, ,
1 get the correct stock rom for your region&vendor
2 flash it
thats it.
Sadly lots of times this is shortened to
1 get stock rom
2 flash it
and people just assume they can use any stock rom, and since they usually already have HSPL installed, it allows the flash to start, and tmous phones die.
Yeh think the HSPL installer should of had a TMOUS version either blocking known bricking radio & ROMs or just an on screen message warrning & advising on checking before comencing with flash.
At end of the day it is the users fault for not researching or using a TMOUS rom to be 100% safer !

[Q] No 4g/3g, only data through wifi

A couple weeks ago, I decided it was time to root my phone, since I missed running the custom ROMs on my Droid. So I unlocked it and rooted it and everything went all fine and dandy. I decided for my first ROM, I would flash Xtreme Outcast's ICS ROM (v2.0, I think). When I first flashed it, my data worked fine (however downloading apps from the market gave me some issues, but I think that was another problem..). However, before long, like later that day, the 4g and 3g stopped working. After it stopped working, I decided to try to restore my nandroid stock ROM, but when I went back to it, not only did the 4g and 3g not work, the wifi just said 'error' when I tried to turn it on. So after that, I tried to flash the GB OTA RUU, but that gave me some issues, but I've figured out where that went wrong (mainver error).
Anyway, what I'm trying to figure out is what I can do to try to fix the issue. My mobile data IS on, the battery cover IS on, and the SIM card is inserted and, to my knowledge, working just fine. Would flashing an RUU help? Am I just having bad luck with this ROM and need to flash a different one? Should I update to the new RUU? Any help would be fantastic, and I'd award you 456789876435974 awesome points!
Sounds like you may have had a bad ROM zip. I would try re-downloading the ROM and re-flashing making sure you wipe all/factory reset first. If that works and you are feeling adventurous, I highly recommend Scott's ROMs new CleanRom 4.1 which requires an RUU. Check out his web site and developer thread here for more info. I took the leap and love it.

Thanks for the response, but do you think it was just a bad flash if it affected the stock nandroid backup too? I will try flashing a new ROM soon either way, though. Is it possible to download an older version of CleanRom? I can't find a link on the first page of the thread, though I might have just overlooked it. I'm just not sure if I want to update to the new RUU right now, but if there are no other options, I might just pull the trigger on it.
Go to Scott's ROMs web site and you can download ISCE 3.7 which is still on the old firmware so no RUU needed. His roms are pretty slick and he provides great support.
Good point on the nandroid so I'm not sure what's going on. Hopefully the new ROM flash helps.
Well, I flashed the ICS RUU, and now my data works! but now...I can't get my phone to root. Is there a guide for rooting on the new RUU?

It is just easiest to install and ICS new firmware ROM that is already rooted.
There is however a couple of thread in the development forum on rooting and there is an ICS root tool there

Reverting to Gingerbread from ICS

I've been having some issues with constant reboots and phone signal strength after installing ICS. I have tried both methods (fastboot flashes and CWM flash) and still have the same problems.
Unfortunately, I'm a newbie, and was an idiot and did not create a backup.
I would like to be able to revert to the last stable official Gingerbread. Any recommendations on version to revert to? I'm been searching here for hours, and every time I think I find a good thread on how to do this, the links to the files are all dead.
Can someone please steer me in the right direction.
Also, again, I am willingly admitting that I'm an idiot for not making the backup in the first place. I saw that so many people were having no issues at all, so I assumed I would not either.
Thanks.

I recommend you the ROMs NottachTrix, it has Aroma installer and lets you configure it to your own taste. Guess this one is the best, if not you could go with a stock GB, search for fruitcakes (don't like them because the bloatware).
I'm assuming that you already have or know how to install a recovery. If it's not the case, let me know and I'll help you.
Thanks. I have CWM loaded so I shouldn't have an issue.
I think I would have the best luck with a stock ROM for now. The problem is finding a stock unlocked ROM for GB that still has a valid link. 90% of the links I'm coming across here including fruitcakes are all dead links.
http://samcripp.com/files/
you can find fruitcakes here. works from your phone or computer.
be sure to thank Sam Cripp for hosting the files for us. and the project in the first place.
Thanks. I was able to restore back to GB, but unfortunately still have the same signal strength issues.
have you tried to flash a new radio? there are plenty of radios on that website as well.

HTC Sensation Z710a Changing OS

Hi,
First of all, I have next to no knowledge of anything related to operating systems and my phone and so on, but I can follow instructions well if explained in simple terms. Thank you in advance.
I bought a HTC Sensation Z710a from Ebay and I didn't realize that it didn't have the "normal" Android on it. I've had it for a while now, over a year and I only recently revisited the subject of my OS when I realized I hadn't been asked to update anything like my previous phone (Nexus from Vodafone). I looked into it a little and it appears I have Android 4.0.3 but "Android Revolution HD 6.6.0 XE" by mike1986?
I would like to know what the best thing to do here is, as I would like to update to the newest available Android out for my phone, and I think I would prefer the "normal" Android to the mike1986 development version (but whatever works I suppose).
I have absolutely no idea how to go about this, so any help would be appreciated. Also, my battery seems to be dying a lot faster these days. Will getting a new one fix the problem entirely, and will updating the OS aid in this at all?
Thank you!
Any help!
Please, I really need assistance with this. Thank you!
I would suggest you to take a look in the section for your device for a custom rom which you think look's fine for you and also I'm quite sure that you have a CWM recovery and unlocked bootloader on your phone so that's not needed to be added.
Well, after that simply download the rom and put it on your sdcard and flash it with CWM, sometimes you might need to update the radio to get everything working. After you have flashed the zip you need to wipe data / factory reset, otherwise you might get a bootloop.
I also suggest you to make a nandroid backup before continuing to flash your device
Okay, thanks. Is it at all possible to get the regular version of Android on it though?
