how do i un-root my phone? - G1 Q&A, Help & Troubleshooting

so i did the 1-click rooting thing BUT the problem is that i wasnt supposed to let my phone reboot into normal mode and that caused the process to become undone. now, when trying to boot into recovery, i get the exclamation mark with the 3 options. please help me @[email protected] i'd rerun the recovery flasher program BUT my phone was wiped too and i cant get past the gmail screen. i have no data plan
android reflashed my recovery partition with the built-in backup DDDDDDDDDD:

If you get a recovery image when pressing home and end than youhave a recovery just boot a rooted rom like cyan's in and you will be good to go, you can acess your sd on a computer by going into recoverey console and typing ums_enable to mount your sd and ums_diable to unmount

i dont think i can, because my phone rebooted into normal mode and android reflashed my recovery partition with the built-in backup, so i dont get the usual recovery mode screen. i have the exclamation markw here you have to press alt+L and theres only options to wipe, install the update.zip and reboot.

Alright then you will need to find a way to acess your card like another phone or card reader if you can not get past that, once you can read, download a rom and rename it update.zip, if you are windows it hides the extension so just rename to update, by the way how did you get the orignal recovery if you used the one click witch flashes cm recovery 1.4 were you have a lot more options and don't have to hit alt-whatever

i did use flash cm recovery. but like it said, after rebooting into normal mode on accident, android reflashed my recovery partition. i wouldve had the screen with more options if that hadent happened. and i wiped too, so i couldnt access the phone due to being locked out because of the stupid log in screen. by the way, do you know how to get past it without another sim and data plan?

The recovery image is immune to wipes and partion cleaning, it is deep in the sif you get acess to your sd and put a rom on there ystem, without an adp phone, there really no way past that login without a custom rom, yes painif in the ass, try another sim get into phone and reflash the recovery to go any farther, once you have cm recovery 1.4 than you can really go, if you can put a rom on your sd before reflashing recovery and you can not get it go past the recovey that you are on now than you do not have permission and you are not rooted

[Q] Stuck on the clockwork recovery menu, help!

I flashed the Tayutama 1.0.3 captivated ROM, then I used the clockwork recovery to replace the glass lock screen by the Froyo stock one.
Now the phone automatically boots to the clockwork recovery screen, tried to take the battery out but no use.
I still can boot to download mode, but the point is that I left something important in the old system, and now it seems I can't take it out because of this bug.
Any idea?
Fixed it. Here's the tips for people who have the same problem as mine:
1. Use clockwork create a backup.
2. One click flash
3. Install Tayutama's ROM
4. Use clockwork again, choose "Advanced restore" and "restore DATA"
It should work.

Did it wipe your data? Or is it in a backup? You could ADB pull the file/information if its a picture or file .... IF you didn't wipe your SD Card.
Also you could attempt to find Tyutama 1.0.3 ROM and find the stock lock screen and try and push it back on and see if your phone reboots.
But rule of thumb:
Always put a backup of whatever your about to screw with on your SD Card. You can use root explorer/ADB/Little Green Men to do it.. doesnt matter how you get the file.. important thing is to have it on the SDCard.
When it fubars you can always (usually) copy the backup back to the location where you fubard it - and *voila* your phone should boot right up.
I have done this (countless) a few times and have always been able to restore the phone to have it boot up enough for me to either re-flash or go on my merry way.
Good luck.

[Q] Interesting boot loop problem.

2 nights ago I thought I would have a go at installing ULTIMATE ROM 3.0. I have flashed many Roms on my Galaxy S before and not had a problem yet. I have ClockworkMod Recovery 2.5.1.0 installed.
However, this time- something went wrong. I don't think the installation completed properly. When I tried to reboot the system (to go back into my previous ROM) I wasn't able to. The Samsung logo appeared before the phone booted back into Recovery mode.
I tried to re-flash my previous working update.zip but had problems. I wasn't able to properly re-flash as the Installation would abort for various reasons. After doing cache clearing and data/factory reset I still had no luck. I resorted to reformatting the sdcard. Still didn't solve the flashing problem.
Throughout the whole time I was able to adb into the phone, browse the file system and I could push files on to it and take files off. But Kies wouldn't recognise the phone and Odin isn't able to complete a transfer to the phone (not sure why).
Today, I am able to successfully flash update.zip files (at least, that's what it looks like) but the phone ALWAYS boots into ClockwordMod recovery.
I am fast running out of ideas. Does anyone have any suggestion?
How can I tell if my ROMs are really 'there' but I can't access them because ClockworkMod is preventing them from booting?
hmmm... me too.. stuck in a loop, that keeps going back to the CWM recovery menu, and no matter what i do, keeps going back to it... cant even get to the download screen to flash (again).... here i was thinking no matter what happens when installing custom roms, i can always flash to my stable secure rom, but not this time... need some software that can perform surgical operations, any suggestions?

Thats too bad guys,and i m sorry to hear that news.I would like to havean answer but i dont...
The fact is that since most people in this forum use some custom roms,and all of us think the same,that we can always go back,so it would be great if you give some more details about what happened to you,and mybe why it went wrong,and it would be even better if one of the BIG guys would give some explanation about this...
I already thinking of not updating my rom anymore,dot want to end up in looping too,so lets see if someone will find something.Good luck guys..
By the way,i didnt get it right,CWM recovery cannot load your backup????
I just got an idea,but not sure if or how it would work or not.
Since you can push file with ADB,if soeone made a clean backup with his CWM (o e mail,contacts,setting saved) and send it to you,so that you log in with CWM recovery and flash that ???
Just an idea..maybe stupid dont know...
Its not very clear if youve tried this already but cant you just boot into recovery through adb? or does that not work either?

[Q] Help with semi-bricked Sprint Hero CDMA

Hello All,
I believe my phone is either semi-bricked or completely bricked. I was in the process of wiping my system to load a custom ROM when I accidentally pressed the trackball and selected 'Reboot Recovery' in Recovery mode:
1. Wipe Data/Factory Rest
2. Format Cache
3. Format Boot
4. Format System
5. Format Cache
6. Format Data
7. Format Recovery
8. Wipe Dalvik
9. Reboot Recovery [WHOOPS!!!!!!]
Now my system is stuck when it boots up normally on the HTC screen. Attempting to go to Recovery by holding down the DOWN VOLUME provides me the menu:
- Vol Up - FastBoot Mode
- Back - Simlock
- Home - Recovery
With the following information displayed:
HERC XC SHIP S-ON
HBOOT-1.47.0000 (HERO200000)
MICROP-0110
TOUCHE PANEL-SYN0104
RADIO-2.42.02.10.29
Mar 1 2010, 16:02:39
HBOOT
Selecting Recovery sends me to the HTC screen with the FastBoot USB text displayed and it just sits there. I am not able to recognize the device via the ADB console nor HTC Sync.
Any ideas how to get thru this? The recovery.img is on the SDCard and all, I just can't get the phone access and load it into the system memory?
Thanks in advance,
GP
are you using CW or Amon?
well regardless what recovery youre usinghaha, you need to plug your phone in your pc (charge only) and boot into recovery and mount your sd card in recovery, i forgot what thats under, but find and and click it and should pop up on your pc with your open files option, put the rom of your choice on the sd card, unmount the sd card through recovery, reboot back to recovery, wipe again and install the rom, and that should do it.
pm me if you need more =]
Unfortunately that is the problem, I cannot get into the Recovery to see all the standard menu options to even select and mount the SD Card.
I am stuck at the menu showing only these 3 options:
> Vol Up - FastBoot Mode
> Back - Simlock
> Home - Recovery
Selecting Recovery locks up displaying FastBoot USB.

Go in to Fastboot USB mode & Re-Flash recovery using ADB. Then reboot recovery & you should get back in.
Or search for a HERCIMG.zip that has the recovery you want. Save to SD root & go in to HBOOT it should see the HERCIMG & ask you to apply the update.

Yeah what he said, only since your bootloader is s-on you can't use fastboot or hercimg.zip. You need to flash a recovery from adb. For future reference the part you messed up was when you formatted boot/system/recovery - those are unnecessary when flashing a new ROM. The reason your phone is mad is you took EVERYTHING away from it and didn't replace it with something, so in a way, yes reboot recovery is where you messed up. But it would've been the same if you rebooted the phone too, cuz well, you don't have a phone, you wiped it. It's an easy fix, and once you get a new recovery you can resume whatever, flashing a rom, restoring a nand, etc.
EDIT: just saw you can't get adb.... try this thread http://forum.xda-developers.com/showthread.php?t=958968
off topic, but when and why would you format anything (boot, data system, cache)
besides using Firerats

Well, because phone cleanliness is important. FYI "wipe" and "format" are the same thing. Depending on what you're doing, you may want to wipe certain things individually. Cache and Dalvik Cache should be wiped every you flash a new version/release of your current ROM or a new kernel. Sometimes wiping those two can help if you're having weird issues. Data should be wiped if you're trying a new/different ROM. System and boot get wiped by a ROM flash automatically. It really depends on what you're doing, but wiping/formatting is needed.
sweet thinks for the info..\hey if you can, could you look to my other issue im having?
its in q and a and called adb shell... $?
Thanks everyone for your help! I finally gave in and did what I should have done initially...I went to the HTC website and downloaded the 2.1 RUU update and just ran that. Now I am able to get the phone operating like new!
HTC HERO (SPRINT) 2.1 SOFTWARE UPDATE | 05.19.2010
HTC Hero CDMA 2.1 RUU
I'm still curious though how come all the recovery images I was trying to load using fastboot kept failing due to data length too long or there were too many links.
Anyhow, all is fine now. Thanks again everyone and for those who have a similar issue if you spend more than a few days and can't figure how to unbrick your soft bricked phones just install the original RUU or grab the latest one from HTC and you should be able to get back on your feet again.

hey what ruu did you run? im trying to downgrade
I used the 2.1 RUU from HTC's website for Sprint Hero CDMA.
Then I ran the auto rooter from:
http://forum.xda-developers.com/showthread.php?t=909258
If you are trying to downgrade I believe you just grab a 1.5 recovery image and clean your system and load it?
http://forum.xda-developers.com/wiki/index.php?title=CDMA_Hero_ROMs
If that does not work, at your own risk do all your standard backups and wipe your system then grab the 1.5 RUU (RUU_Hero_C_Sprint_1.56.651.2 signed release.exe) from geekfor.me and run it. I'm only guessing that was going to be my last resort if I hadn't been able to root my 2.1 installation.

[Q] Bootloop hell

I apologize in advance if this same issue has been replied to elsewhere. I'm in kind of a unique situation and couldn't find an answer anywhere.
I'm got an N1 with 2.3.6 stock ROM, rooted. Recently I downloaded Titanium Backup PRO and while attempting to integrate dalvik cache to ROM, my phone rebooted into a bootloop. I'm assuming this is a bootloop. I get the colorful splash screen, it freezes for a second of two, then continues on, and on, and on....
Is there a way to get me out of this loopwithout having to wipe all my data, so I can backup all my stuff before I flash a custom ROM?
Everything I see about bootloops, mentions unlocking the bootloader and wiping all your data. I've seen downgrading using PASSIMG and loading stock rom. I'd really just like a simple way to get out of this loop hell and get my phone back up. It's in teh ship now getting it's power button fixed.
Thanks in advance
first thing i do on bootloops is pull battery
if no go pull battery and then pwr on by pressing pwr and trackball at same time--you can then get to recovery and maybe wipe dalvik and cache and reboot
i have never used TB for anything other than backup/restores, so can't help with dalvik integration
You might be able to fix it by wiping your cache from recovery.

Thanks for the advice! I'll give it a try as soon as I get my phone back from being fixed.
Hey guys, I hope you can help. I got my phone back with new power button, Yay! When I try to boot into recovery, teh Nexus X logo comes on for a moment and then I get a white triangle with an orange exclamation point. Do I need to use ADB to try and go to recovery and wipe my cache? I've never installed a recovery image. Do I need to do that or should there be a stock image already on my phone? Am I SOL?
One more thing that might help. I notice that when I go into HBOOT, the phone searching for 4 images from my SD card and can't find them. They go by too fast to write them all down but I think some are PASSIMG, PASSDIAG, etc. Again, do I need to load a recovery like clockworkmod on my phone first and then go into recovery to attempt to wipe my cache?
I get the same passimg all the time--no problem
If your phone came back from repair, you are probably unrooted and hence the triangle. At least that is the way I remember it, but has been two years since I rooted
If that is comfirmed by someone else, you wil need to reroot and install a recovery
A good time, if you haven't, to install android sdk and root/install recovery the right way and have full adb/fastboot features
there other ways I am not familiar with
does the lock show unlocked on the screen, they could have relocked bootloader
the wiki has the instructions, just have to navigate to the htc smartphones and N1
jus to make sure that if u still got root. install su checker app from play store and confirm.
if not root using SUPER ONE CLICK ROOT.
flash recovery (4EXT is good) www.4ext.net
do a backup and then flash the rom u want

Thanks I'll check. I only had teh power button fixed and not by HTC so I doubt they unrooted it. I'm still in a bootloop but I can use superoneclick still, so I'll give that a try.
so what I'm trying to do is wipe my cache without wiping my data. I don't think my bootloader is unlocked. Am I screwed?I'm in a bootloop, so I can 't install anything to the phone. I probably could put a recovery image on the SD card, but if my bootloader is locked, I'm guessing that won't work. I'm rooted. When I go to HBOOT, the phone looks for passim files and doesn't find them, then when I choose recovery I get the white triangle. I've try to flash a recovery image through ADB but I get an error, failed to load image. Again, is that a bootloader issue?
I'm almost at the point of just wiping my data and hoping I can get it all back somehow.

You really know nothing huh. The triangle is the recovery. Press power button and volume up at the same time, it will the show you some options like wipe cache.

Did you miss the "stuck in boot loop" part?
sorry,
meant that the triangle is your stock recovery--
you install recovery thru fastboot not adb
i would still, if you haven't, install android sdk on pc-unlock bootloader (fastboot oem unlock) and fastboot recovery--all in wiki
i think it was mentioned--holding down pwr and tb will get you into fastboot mode--phone connected and usb debugging selected on phone
you'll just have more flexibility with flashing roms etc and getting out of trouble

cant get into recovery

Ok not sure what happened. I have even flashed the vulnerable recovery again. I have tried 2 different sd cards now and cont seem to get tinot recovery again. I currently have the froyomo 2.9.3 isntalled on it. want to get this device up to ICS
The only think I have not done is reflashed the GOT 2.2.1 recovery but I didnt think it would be necessary and I was not able to find a valid downlload likn.
I get to the triangle but for some reason just does not want to load the recovery at all?
any ideas?
delete threat I seems to be dumd. Just had to hold down camer and volume up to get into proper recovery
