Un-root CDMA Hero (Sprint)

I have an HTC Hero running Fresh 0.7 with the two-part patch applied. I would like to un-root the phone if at all possible. I have attempted using the RUU utility, but received an error code 170 when I ran it. The error indicates a USB connection issue, but the phone is definitely plugged in and has all drivers installed (I have the SDK and ADB drivers installed).
Can anyone give me a hand restoring my phone? Any help is greatly appreciated.

try booting into fastboot mode (hold vol up and power on) then run the RUU utility. This method has saved me at one point!

saved me too! I got into a pickle when i flashed a cyanogen 6 rom. The rom worked but for some reason my sdcard would not mount, keep getting
E: can't mount /dev/block/mmcblk0
p1 (or /dev/block/mmcblk0)
so then i tried fastboot and made sure usb was connected ( fastboot devices )
and still had problems.... fastboot failed, remote: not allow .. so after a couple of days reading forums i tried running my phone in fastboot usb ( made sure was connected through command on pc ) then ran Hero_C_Sprint_2.27.651.5_R_2.1update.exe utility and Bam! Loaded up back into stock. haven't had any problems and my sdcard works again

Fastboot mode has always worked for me. (Volume UP + Power On)

i have a question, i am taking my phone back to sprint today and if i just flash the RUU will it be fine, or will i have to unroot it??

it's right there in the thread you linked to.
1. Simply rename this to HERCIMG.zip and place on the root of your SDCard.
2. Power your phone completely off.
3. Press and Hold VOL DOWN and POWER until your phone boots into HBoot mode.
4. Wait for it to verify the zip, then click <ACTION> (Trackball) to update, or <SEND> (Green Call) to cancel.

If your running Windows 7 and get error 170 just exit out of the program, unplug, plug it in and rerun the program. That's what worked for me.

Bricked phone ?

Hi,
I tried to upgrade from v2.1 to new Android 2.3.5 Gingerbread For LG Optimus GT540 and I followed instructions exactly, but I am stuck at number 8, I did this:
8- Now click “Launch software update”, DO NOT USE THE PC TO THE PROCESS IS COMPLETE. THE PHONE WILL REBOOT WHEN FINISHED THE PROCESS IN KDZ. (The process takes about 15 minutes in KDZ).
and about 2 minutes text log writes and stopped, I am now waiting more then 40 minutes my phone didn't reboot. On display is still written download mode, what should I do now ?
In kdz is written:
3GQCT: wParam = 205. IParam = 36
p.s.
I disconnected phone from usb and pull out battery and now I cannot turn on phone, I tried to push vol down + power for 5 sec.
Any idea what should I do now? I hope I didn't brick my phone

What programs are you using?
What are you using to update your phone and have you tried taking out your SIM, SD card and battery then turned it on with the USB cable?

I used KDZ updater and tried to install CyanogenMod7 (2.3.5) @ GT540 Swiftdroid2 RC3 by Mur4ik. if that is what you ask ?
I removed sim card and battery also, then tried to turn it on while plugged in to computer usb but no response from phone, I can't turn it on
p.s. I am using win 7 64 bit OS

If you can't get into download mode, then it's game over I'm afraid. What you will need to do is return the phone back to where you bought it. This happened to me some time ago. But the Carphone Warehouse were happy to fix it (even though I had voided the warranty but don't tell them that ). Don't say that you tried to mod the phone, say something like 'I installed LG's PC Suite and it said my device had a software update. I went along with it, but it gave me an error half way through. Now my phone won't turn on at all' It might just work!

I had the same problem when modding with kdz.
completely bricked my phone, but was able to fix by putting kdz into emergency mode instead of diag and updating with a fastboot stock rom,
it would stop after 2 minutes and give me and error but it managed to get fastboot onto my phone,
(camera + power)
then just flashed the fastboot method with adb and everything was fine,
my problem was something to do with lg modem drivers i believe,
I read a thread that said to disable the lg virtual modem. (didnt
work for me)
pretty noob myself
but the above method worked for me,
not sure if this can do anymore damage to the phone

have a look at this is u get it into emegancy mode.
On the kdz updater instead of 3GQCT put into emergancy

If you have tried flashing with Cm7 you might be lucky,
try holding camera button and powering on the phone, a black screen should come up thats fastboot.
if that comes up u should be able to just reflash following mur4iks instruction
if not try what i said in my last post and reflsh with phone type 3QGCT and PhoneMode EMERGENCY
again only going of how i fixed my bricked phone

He was trying to flash a fastboot rom (to install CM7) but bricked his device in the process. So he can't flash CM7-.-

Yeah I know that but I mean when I got the error he has, I flashed with a stock 2.1 fastboot rom With Diag changed to EMERGENCY and was able to get on to fastboot mode (camera+power), I got the error again as i was flashing but the phone would load fastboot and not start up
If he can get lucky and get into fastboot like i did, a simple:
fastboot -w
fastboot flash boot boot.img
fastboot flash system system.img
fastboot reboot
should fix his problem or did i just get lucky?
sorry if im confusing thinks here, but this is how i fixed mine. which was also dead and not turning on

Well like i told you im a noob at this myself (Android phone flashing atleast)
I suppose it would be good to see if you got fastboot??
Power on the phone while holding camera button (hold the camera button until the screen goes black) if you can get fastboot you can just follow the fastboot flash instructions after fastboot -w
if not on kdz in the top right were it says DIAG, Change this to CS_EMERGENCY,Click Launch update and flash again with a stock fastboot rom
after THIS see if the phone loads or boot loops(had this once too) or loads fastboot
Il try look to find the thread i read on another forum for troubleshooting kdz it helped me alot
EDIT: http://android.modaco.com/topic/321895-faqgt540-reference-thread/ try some of the troubleshooting tips at the bottom of the O.P
I basicly aimed to get fastboot working so make sure your flashing with a stock FASTBOOT! rom
again im new to this im just saying what got my phone back to life

I bricked my phone and I tried it again after getting it back from lg

I'm new here and to having a Smartphone, I've just been given an LG Android GT540 which is at version 1.6. The LG site tells me I can upgrade to 2 something or other, sorry can't remember the exact number and gives instructions on how to do the upgrade, but I'm a bit on the cautious side as I don't want to brick it, not this early on in owning my first Smartphone.
I'll be reading a lot of the posts here to try and find out as much as I can before I attempt to do this.

Well don't worry if it's official update. But if you some how brick your phone just tell lg the update bricked your phone and we are talking about unofficial updates

[Q] gt540 fastboot error :(

believe it or not i am stuck with the 'camera+power' button combination.
i have tried it a hundred times and different style of pressing both buttons but nothing happens, it's just run into normal.
what should i do???
i have made all of the downloads and instructions..

Flash new ROM with fastboot.. I recommend Official 2.1

is it the rom Europe version 2.1 that I downloaded and upgraded it to my gt540? and causes to not able to make a 'camera+power' button combination?
where can i find that???
can you give me the link??

Yes.. -> http://android.modaco.com/topic/311477-lg-gt540-rom-updates-from-lg/

The file names are the same, but the files are different. Flash the one from the provided link, and you should be fine.

No problem you need to flash that KDZ file to get official Android 2.1 ROM with fastboot.. there is no diffrence between KDZ file on your PC and KDZ file on MoDaCo forum.

okay2 thanks nutter! i am now currently downloading the V20A_00.kdz that droid00 gave to me.. just a 25mins after this download i'll try to launch the kdz updater and update with the new v20A_00.kdz. i wished i'll make it right.. please help me..

i made the flash again to my phone twice. but still can't access to the fastboot mode with the same button combinations of camera+power. argh!!! i quite pissed off to these guys.. help me out here (

Subsitute
Try holding the camera button when you see the LG logo. Is there any physical problems to the buttons?

I used this tutorial using the files on it and everything worked just fine, I was able to turn on the phone in fastboot mode and flash CM7

thanks jhonny and ernub!
i have this thing the V20A_00.kdz, and i used that download to flash my gt540 in the kdz updater. i have been updating this phone thrice now and it seems that i has no IO File, taskiller and the one i forgot it thou sorry! and it has a added app of the sims3 the foursquare.
about the fastboot thingy. i dont know if it has to do with the camera button? idk if it has an error or something. promise! i tried it several times since last week! and im very stuck with it that i could not go on with the next step..
still I'll try my luck of pressing both buttons. is it has a trick or better way in fastboot???

youtube.com/watch?v=t2exzAMBh64&feature=channel_video_title
just add the 'www'
here's on how i do the 'camera+power' buttons. and nothing happens. its just run normally.
can you show me a clip/vid on how to do the fastbooting pleaseeee???? im begging.

I just watched your video and seems like you're doing it fine, the only thing i can think of is that your camera button is physically damaged

I have noticed that no-one has suggested flashing a fastboot rom-.- Only the V20A_00.kdz, which does NOT contain fastboot.
What KDZ did you flash? The one from csmg.lg.com or a different location, if you downloaded it from csmg.lg.com, then no wonder you cannot get into fastboot, you didn't flash a fastboot ROM.
Otherwise:
Try flashing a different fastboot ROM such as V20A Europe with fastboot, or Orange France V20C
Hope it helps.

idk what website it is, 'cause a lot of folks suggested any sites for me since i was in fastboot process and I'm totally stuck now with the 'cam+power' combinations!
right now I am downloading the franceOrangeV20C and hope'll works...
I am damned quite pissed with the europe version. otherwise, if the france version don't work, it would probably on my phone's physical condition in the camera. but when i use the camera button when i take shots, nothing wrong happened with .. hmmmmm.....

Volume
My volume up button doesn't work on ClockworkMod Recovery
Maybe I need to re-flash the current recovery or wait till the next one come out.

Hey simeus, the optimus gt540 aka swift has a few versions, i.e. mine is GT540f. It seems some of them don't have a display when in fastboot mode, check if your screen is "on" but black when you do power+camera, you may be in fasboot mode and you don't know it, my phone does that, no animation, no LG logo

Also, you can see if you are in fastboot because you will be able to see the backlight. Also, if you run fastboot devices, it should return:
Code:
list of devices attached:
? fastboot
That means your device is connected.

hello guys! my bad! soooorrryy if im not able to send in my responses immediately. btw, i can now manage to fastboot this phone and i truly recommend to you guys to use franceOrange version! you can see that link in the first page.
now, my only problem is that i am stuck with the:
fastboot flash boot boot.img
fastboot flash system system.img
it says 'error: cannot load boot.img'
and the 'system.img'

how can i know the location of that two??
can you send the link downloads of that boot img and system img??

[q] problems with lg gt540

hi guys.. could you help me with my problem.!
I have an LG GT540 android 1.6 firmware version(stock)
So here are my problems:
1. I tried to upgrade it from 1.6 to 2.1 using this tutorial http://forum.xda-developers.com/show...27&postcount=3 thanks to lavero.burgos for posting it, I was successful at first part, but I cant follow the next because my device wont go to fast boot,, I tried putting it off, then camera+poweron but it doesnt do anything. It doesn't light, no lg logo appears, just nothing although the computer can read the drive when I connect it through usb. So I cannot flash it to 2.3,2.3 because it just wont go to fastboot.
2. When I turn it on normally, It takes long before it response like after 30sec to light, but just light, no lg logo appears although it wasnt bricked because I can use it normally after just waiting to on.(annoying)
3. Since I upgraded it to 2.1, I lost all 3rd party application and the internal apps were the only left, so I copied all my saved apps (.apk) to my sd card but the problem is there is no saved app on my phone to read and install those apps from my sd card.(irritating)
4. My device wont read my sim card, when I start it it says "sim card unprovisioned" so basically I cant connect to mobile networks here in the philippines(im using globe telecom). I feel that Im stucked in the middle of nowhere since I cannot contact and txt all my family and friends.
5. I cant connect to wifi,, when my device detects wi-fi, I try to connect to it but from the log it only try to connect but doesn't obtain the ip address. Even when the wi-fi signal is strong, it does the same thing.
So please help me guys,,I want to hear from my fellow xda-developers badly,,,
PS. also those who have problems with their LG GT540 pls feel free to post and share it with us here... thank you all guys in advance....

hmmm maybe there are no fastboot drivers(main suspect....) there are a few ways to get it but for mine i just plug my phone in to my pc (windows 7 64bit) it just recognize it and tries to get the "google fastboot interface" drivers from windows update...

Try Volume Up+Search Key+Power to go into Fast boot Mode, There's different keys to activate Fastboot Mode (There is different versions of Fastboot)

Your phone is/was bricked
Hey, I'm sorry to bing back such an old thread, but I just wanted to say this for posterity: your phone has/had a soft-brick. This means: you can't see Android nor LG boot logos, can't enter Recovery and (maybe) can't access Fastboot, but I'm not too sure on that last one. Besides that, the phone works "okay", but you should try to fix it.
Basically this soft-brick is almost always caught when upgrading from 1.6 to 2.1, so everyone should have it, including me. It took me a whole year to realize how to friggin' fix it lol, but here goes what I did:
Thanks for your help everyone, I came to a solution after a full year lol. Here's my enlightenment, from another Thread:
------------------------------------------------------------------------------------------
Just wanted to leave my 2 cents here, I've been trying to do my best since around august 2014, no success. 2 days ago I retried this, and I DID IT! I will tell everyone what I did very shortly:
My problem that I solved: I can boot, device works like a charm. But: no boot logos, no recovery.
My solution for TL;DR: UNINSTALL ALL DRIVERS FROM DEVICE MANAGER 1ST, then reinstall. After that, flash a fastboot ROM and use it to WIPE ALL THE DATA IN YOUR PHONE! THIS was what I needed and was never explained: you had to WIPE the old data in order to get the boot screens back.
IN THIS ORDER (THANK YOU to those people from previous replies, gathering all your info was of great value):
Uninstall all of your phone drivers from your PC!!! This is what made most of my headaches go away, just use Device Manager and uninstall anything from LGE. After that, plug in your device in your USB ports (always BACK ports, not front ports, important). It should detect all drivers and download them.
IF it fails (it generally does with LGE USB Modem), you can go to Device Manager > Unknown Device (the one that wasn't recognized) > Right Click and Update > Choose 2nd option, then choose "choose from a list of local controllers" (or whatever the button says). After that, scroll down to LG Electronics, Inc. and install what didn't install.
I also found these drivers, but I did not test them: http://www.mediafire.com/download/p693hcz6kkouh19/USB_Driver_LG_GT540.zip
Huzzah!
Now you're set to begin:
FIRST thing you wanna do is a factory reset, this is something I'd forgotten with time, don't make the same mistake as I did. You can do it by turning your phone on and pressing Volume +/- & Home & Quick Search buttons all together for 5 seconds (it works, be patient and wait for it, even if you open the camera or any other stuff).
Download this Google SDK Tools (unzip and put the folder in C:\ drive) and this Fastboot drivers for GT540 (unzip and put the files inside the folder in C:\android-sdk).
Skip this next line if you know your ROM has fastboot.
Now, if you don't have a ROM with fastboot, I recommend you use either European Open+Fastboot or V20C Orange France Fastboot ROM.
Click to expand...
Click to collapse
Since you have Fastboot enabled, now all you need to do is turn off your device (all this with its battery on it, no weird things) and hold the Camera button before turning it back on. This should take you either to a black screen, or simply to no display, like me. Either one will work anyways.
Now press the Windows key > Type cmd and open it with Right Click > Run as Administrator.
In it, type all this, command by command (you can paste by right clicking):
cd C:\android-sdk
fastboot -w
fastboot erase boot
fastboot erase system
fastboot -w
fastboot reboot
Click to expand...
Click to collapse
And now it's go time! Do what everyone else says in here: Take out your phone's battery, SD and SIM cards, fire KDZ Updater up as Administrator (If your KDZ freezes, then it's either faulty or you did not install msxml, look for a good KDZ that comes with that file and delete your current one), choose CS_Emergency PhoneMode and:
1-Plug your phone while holding the volume DOWN button (don't worry! My phone didn't show "Download Mode" either, if you hear the Windows "Somethingpluggedin" Bump noise, it's ok).
2-Flash French V20A
3-Unplug your phone once KDZ says "==FINISHED==".
4-Plug it once again, holding the volume DOWN button.
5-Flash out.kdz (remember! it's CS_Emergency).

Stuck in rescue mode after tried flashing stock firmware

Good evening! I hope you can help me.
I flashed LineageOS 14.1, but I wanted to go back to EMUI. I made all the wipes and tried to flash different stock firmwares through a forced update (volume buttons + power button), but it never worked. At that point, I read about a guy in this forum who suggested to create a flashable zip with Huawei Update Extractor: I followed the suggestion and tried to flash it with TWRP. No error was given, but when I tried to restart, TWRP told me I had no OS installed. I thought it was strange, so I tried to restart anyway. That's when I got in rescue mode. I can't get into the recovery and I can't use fastboot. What rescue mode shows me is:
RESCUE MODE
Attention!
Please update system again
Update User Guide:
*link*
*android avatar*
Error!
Func NO: 10 (boot image)
Error NO: 2 (load failed!)
Pressing the three buttons, I'm able to force an update. The problem is I can't find a firmware that doesn't get rejected. With Lollipop firmwares, it starts to install, but it fails at 12%. With Marshmallow ones, the installation process doesn't even start.
What can I do to make it work again? I'm very sad because this phone was gifted to me a couple of days ago and I already messed it up. I don't even know how to turn it off.
What can I do to get in fastboot mode? At that point, what should I do to flash the stock firmware? Or maybe do I need to find the first stock firmware ever installed into this phone to make the forced update work?
Please, I need help. Thank you in advance!
P.S. The phone's model is ALE-L21. I live in Italy, so I assume it's a European version.

Not yet, but I'm working on it. I found out that the device is recognized by my PC if I follow these steps:
1. Connect the phone to the PC and wait for it to go in rescue mode;
2. Wait until the notification LED stops to blink;
3. Disconnect the USB cable;
4. Press volume - and power button;
5. Reconnect the cable.
At that point, the screen turns black and the phone is recognized as "㄰㌲㔴㜶㤸". I installed the drivers and now it's recognized as "HUAWEI USB COM 1.0". I should be able to reflash the partitions and make my phone work again, but I'm still trying to understand how to do it correctly.
Any help is appreciated!

At that point, the screen turns black and the phone is recognized as "㄰㌲㔴㜶㤸". I installed the drivers and now it's recognized as "HUAWEI USB COM 1.0". I should be able to reflash the partitions and make my phone work again, but I'm still trying to understand how to do it correctly.
Any help is appreciated!

fastboot detects your device when you plug it into your computer?
I mean, if you run "fastboot devices" it shows your phone?
I've had this same problem but with an P8 Lite 2017, after flashing some ROM that supposedly was the stock one and trying to flash recovery I ended up with my phone bootlooping into rescue mode, I was able to "bypass" this thing rebooting my phone like crazy, seriously like after 20 reboot it finally booted into the damn ROM and I never touched the phone again. Sometimes when the phone ran out of battery and tried to power it on the phone booted into rescue mode and again after some reboots it booted to Android but now I want to install a custom ROM or at the very least root this damn phone so that's why I'm asking you if you have solved this, if you do then probably if I follow the same steps I would be able to fix that screen, hopefully.
If you are able to flash something start with flashing all recoveries your update.app has, maybe that's the problem (at least in my phone it is).

No, it doesn't show anything if I write that command...
I guess mine won't ever boot into the rom because it seems like there's no system installed. I made some researches and found out there are some softwares that let you reflash the partitions IF the phone is recognized as "HUAWEI USB COM 1.0". I'm still trying to figure out how to do it correctly though. I feel like if I do something wrong, then my phone won't probably turn on again.
In your case, you should be able to flash a custom rom without any issue. You just have to be very careful and inform you as much as you can: I don't want your phone to end up like mine?. Anyway, it seems pretty hard to go back to the stock rom, so think about it before you flash a custom rom. Also, make a Nandroid Backup is very important.
