How to flash CWM Recovery Touch on T-Mobile G2?

I've been trying for hours and I can't seem to figure it out. I googled counltess times and it seems like other phones get .zip files and the G2 gets a .img file. I'm not exactly a noob, but not exactly an expert so if anyone can help it would be greatly appreciated!

If you have the eng hboot you can do "fastboot flash recovery recovery.img". Or you can flash it from inside ROM Manager. Not sure what sort of zip you have, if that's one that can be flashed from hboot or not.

I've tried the fastboot flash command it doesnt work
and its not a zip file its just .img

Ok so you don't have eng hboot.
Do you have the ROM Manager app installed ? Is there not an option to flash it from there ? Mine does, but I'm not sure if this is only an option for the paid version of ROM Manager.

Yeah you have to pay $2 but I don't want to pay for something that I can get for free. I might be sounding cheap right now hahaha, i don't have a credit card or anything so I can't really pay for it..

Have you tried pushing the file to the phone using ADB?

And then do what after that?

Push the file to your sdcard
Then rename it to recovery.img so its easier
Go into your terminal in your phone and do this
Code:
flash_image recovery /sdcard/recovery.img
reboot recovery
That's it and your done

Or just use the zip thats provided on the clockworkmod site http://download.clockworkmod.com/recoveries/recovery-clockwork-touch-5.8.1.0-vision.zip

Copy .img to desktop
Open cmd prompt, type cd (location of desktop)
Example"C:/users/blah/desktop"
Boot into bootloader. Press power button on g2 to enter fastboot
In cmd, type: fastboot flash recovery (exact name of recovery).img
Let it send and write..done

I actually tried using the ".zip" twice (once from Rom Manager and once directly from recovery). Every time I seems to go well and after install I land in touch recovery environment and think yes this really worked... So then I reboot to recovery and guess what... I'm back in the oiriginal non touch version !!!

OMG Please Help me!

Ok I think I've actually broken my One X.
I was trying to put a default ROM back onto the system, I had my phone plugged into my PC, and "ran Android_Revolution_HD_Super_Wipe_One_X"
STUPIDLY I deleted a couple of files off the SD card in Windows Explorer, and now I cant get into recovery mode for ClockwordMod Recovery (as I'm assuming like an idiot I deleted it somehow)
Literally if I boot the phone it won't go past the HTC welcome screen.
I apologise profusely if this is already covered elsewhere - but I am an absolute noob and do not understand much of the jargon. I shouldn't have messed in the first place, I could cry

1. Fastboot and erase the cache, that will then allow you back into the recovery.
2. Fastboot the boot.img to your phone, as S-OFF won't allow the clockwork to flash it.
3. Don't panic. You can always recover the phone through Fastboot.
I should know, i was once in your position.

thanks for the reply,
I read about erasing the cache, but I have no idea how.
the guide just says type it into your pc
sorry again for being thick!

No problem.
Do you have fastboot open on your pc? if so.
Type : fastboot erase cache
Then download the Boot.img from ARHD, and follow the instructions.
Mike has included a .bat file that will automatically erase the cache and flash the boot image. I suggest going on to his forum and running the file.

I know I have downloaded it (I'm so lost) but the file in my downloads isn't something that opens a program?
Thanks a bunch!

It should have a .bat named install-boot, it shouldn't run a program, but open in CMD with options displayed on what to do next. Follow the instructions and you'll be fine.

ok I don't have a file called install-boot, just adb, fastboot and a few .dll files. both exe files flash cmd but it doesnt remain open.
any chance you can point me in the direction of this software as it would appear i have the wrong thing!

It seems like we need to get back to basics a bit. Are you familiar with MS-DOS? Those programs are not meant to be run from windows by clicking on them. They are run with command lines typed in a DOS type window that is opened when you type "cmd" into your search box in windows.

sorry, confusing fastboot and flashboot I think,
I'm being told that I'm missing adbwinapi.dll - looking into it
I'm no genius but I'm not usually this bad, just so worried - got the phone 12 hours ago, naturally feeling sick!

ok, followed the steps with flashboot (ran the cache delete and install-boot)
still not let into recovery. it goes past the htc sense screen, all black with a mobile with green arrows in a circle (like a sync) which eventually changed to a triangle with '!' in it.
what am i missing?

You can't delete recovery through windows explorer for the record.

That's stock recovery it sounds like. Just relock your bootloader ( fastboot oem lock) then run an ruu. Then once booted you can start all over.

sorry noob alert again: how do i do this?

Sounds like it has the stock recovery on it. Download the Cwm recovery and you should have a file called recovery.img. Place this file in the adb platform-tools folder. Go to that location in cmd prompt then type fastboot flash recovery recovery.img or you can find on xda via search one x all in one kit which if you download and open then put your phone in fastboot mode via bootloader will allow you to flash Cwm recovery and should do it for you

int the adb platform-tools folder? again im very very sorry, but where is this?

When you downloaded adb did you download the exe or zip version. If exe download zip version then extract it place the contents on your c drive then when using cmd use the cd commands to get to the correct folder.

ok, I have managed to boot a recovery (i think) and can now get into CWM, only problem now, is that my PC no longer recognises my phone in order for me to put any ROM files onto the SD card so that it can load them?

Yes Cwm does not support sd mount atm. I think you will need to refer to the post by someone saying relock bootloader and flash ruu. You will need to find and download the ruu that matches your device. ie network your on and country ur in. As I'm guessing you have deleted the rom image of the sd or nand backup?

Holding power button and volume down i can boot into fast boot hboot does not let me select recovery.
clockwork mod and rom manager do not show on apps listed.
looks like reverted to stock tmobile rom but s off and htc vision show up so I may be still rooted?

1. True S-OFF is a permanent type of S-OFF. There are ways to do it temporarily. It looks like yours is perm S-OFF.
2. From the instructions that you followed, did you have to put a PC10IMG file onto the root of your SD card? If that file is still there, the bootloader will always look to that file and not allow anything else to be done.
3. Clockwork Mod will not show in an apps list. It replaces the recovery of your phone. It is not an app. As for ROM manager, I'm not sure what to tell you. Maybe if you can pull logs from your phone we can work on that.
4. Just because S-OFF shows up does not mean you are rooted. If you flashed the stock T-Mobile ROM then chances are you lost root privileges. You can do a quick check by looking in your app drawer for the "Superuser" app. If it is there, you are still rooted. If not, most likely you are not.

Oh! your smart…Yes PC10IMG is still on SD card.
As is superuser.apk and clockworkmod and titamium backup
"Superuser" app is not in app drawer
how would i pull the logs

take the image off sd card and you will be allowed back into recovery, then do a full wipe and flash rom of choice via recovery
Sent from my HTC Vision using xda premium

ok took off image and it allowed me into recovery now i have a cool picture of the phone with a red triangle and exclamation point
update: pulled battery turned it on using only power button goes to tmobile stock screen and works fine. do i need to re root and flash new rom?

need to flash a custom recovery again via fastboot. get the .img from somewhere in xda (or google it)
put recovery.img in the same folder as fastboot.exe on computer
connect your phone via usb and boot into fastboot
open cmd on computer change directories to where fastboot and recvoery image are
type fastboot devices (just to make sure its working)
then type
fastboot flash recovery recovery.img
then
fastboot reboot bootloader
now boot into recovery
now flash rom of choice via recovery

Hello, thanks for all the help.
Am I using ADB AND FASTBOOT or SDK to put recovery.img in the same folder as fastboot.exe on computer

sorry a bit confused on what you are asking
after downloading the sdk package you will find a folder probably under platform tools with adb and fastboot .exe in it
this is the folder you want the recovery image
this is also the folder you want to open cmd
right click in the folder and choose open comand here
then you should be ready to use fastboot
(another option is to change enviromenta variables so you dont need to worry about what folder fastboot is in in the future but not necessary right now)

Any suggestions?

did you get the recovery in an .img or a .zip? if its zipped extracted it
alsom make sure it is named recovery.img
windows adds the file extention so you may just need to name it recovery
Sent from my HTC Vision using xda premium

It came as a disk image file not zipped, until I changed the file to just recovery I got an error cannot load.
Once changed it loaded started recovery and failed.
Ive been reading about eng hboot as mine shows "s-off" not "eng s-off" but I don’t know how it applies to this.

did you follow the htc official dev bootloader unlock?
or did you root following the wiki?
if you did the htc way you are not true soff and you will need to do this first. look for nipqers directions

well you can try downloading superuser and rommanager from the market and see if you can install recovery that way. i think there is a busybox installer app in the market too but im not sure
you can also try with adb

relock your bootloader first
then flash stock ruu
you will be unrooted
to flash stock recovery,extract recovery.img from stock ruu and place it in c:\
connect your phone to pc in fastboot mode (you should have android sdk installed)
open cmd and type "cd c:\" without quotes
type fastboot flash recovery recovery.img
now you should have stock recovery

first of all for fully unroot you need stock ruu (like if your wfs model is european brand your stock ruu is eu 2.26.401.3 )
you can find it in android dev thread>marvel/marvelc stock ruu thread by jmztaylor
then run it on computer..(you can see now update wizard,dont close it)
now open task manager see processes you will see process named ARUwizard (something) right click and select open location.
now you will see temp folder is opened..you will find rom.zip in that folder..copy that zip file (its our stock ruu)
now you can close that update wizard because we got our rom.zip
now renamed rom.zip to PG76IMG.zip
now go to this thread
http://forum.xda-developers.com/showthread.php?t=1530864
and download bootloader control tool.
flash it from cwm recovery..
A Menu-type will appear. It will show you 4 options:
Unlock Bootloader
Lock Bootloader (Guarantee Mode)
Lock Bootloader (Relocked State)
Supervision
Now, choose 2 or 3 option.
Then say "NO" to reboot. Go back to the main menu of CWM.
It'll reboot the recovery and get you the main menu again.
then flash that tool again now choose supervision and reboot..
now time to make gold card.
go here,
http://www.mediafire.com/?hdxoe6e5km434tb
download it and put phone in debugging mode and select mmc00 mmc01 (try one by one till ones give u cid)
then put cid in given website and you will hv now goldcard.img
put it phone in usb mounting mode,and put that PG76IMG.zip on it and patch with goldcard.img
now just put that sdcard on your phone and wait...phone will detect zip and it ll asked for confirmation..say yes with volume up and you will be unrooted after sometimes(this process takes upto 5-10 min)
good luck
IMP NOTE :
AS GOLDCARD CREATION WEBSITE IS PROBABLY CLOSED,FOLLOW THIS TUTORIAL TO CREATE BOO.IMG AND THEN PATCH IT WITH GOLDCARDCREATOR
1) download this and extract it.
http://d-h.st/UGV
2) Start CMD as administrator.
3)Type, then press ENTER after each command:
Code:
cd c:\gcard
gcard.exe -r -c [COLOR="Indigo"]enteryourmmccode[/COLOR] -o Chiffinske.img
4) now rename chiffinske.img to boot.img and patch it with goldcard creator utility.
( thanks a lot to genepool to create this script so we can create boot.img without that website )

My G2 will not boot up correctly

I have the htc g2 and it's rooted, I was running elitemod gb for awhile until yesterday when all of a sudden my shut itself off while I was playing music. I power it back up and when I do it just says system update and it shuts itself up by itself before I can swipe the screen to unlock it. So I thought it wasn't a big deal, just do a complete wipe factory/cache/dalvik and still no dice. So I wiped again and this time reflashed the rom and still no dice. So I downloaded 3 new roms, elitemod ics, cm9 sense and that old stock rooted rom for this phone. And still no luck, everything goes as planned until it finally boots up and says system update and it shuts itself off. I wiped front to back and nothing works. I'm running latest clockwork recovery. So I looked for a superwipe zip or something, I found a thread that has the superwipe g2 and used that and flashed a stock rooted rom and others and still does the same thing. My last and final theory of a remedy is to use a different recovery, but I can't download 4xt recovery cuz I can't use my phone, so I tired the downloading the zip by itself on my wife's phone and on computer but clockwork says aborted. Can anyone give me the recovery zip or have any ideas on how to fix my current issue?

Download the image from 4ext website, then wipe and flash the image via fastboot

Can you tell me a step by step on fastboot method? I have the recovery.img file on the root of my sd card but it doesn't do anything when I press fastboot?

correct, fastboot is a .exe program tha works similar to adb, which if you rooted you own phone then you should have some familiaity with it
I assume you have a pc, so simplest way is
rename and put the .img in the same folder on pc as fastboot.exe (probably platform-tools in the sdk)
now plug in phone and boot to fastboot mode
hold shift and right click in the folder with fastboot and image and choose open command here
now type fastboot devices, you should see your serial number
now type
fastboot -w
now type
fastboot flash recovery recovery.img
now type
fastboot reboot bootloader
now reboot to recovery

Why does it have to be so complex? Why can't there be a flashable zip that you can flash in clockwork like many devices? Is there a flashable zip? That would be more simpler. I do have my pc, and it was a pain in the ass to root this phone since it was my first time downloading the android sdk and the other stuff that told me to download.
