Blank Screen

My G2's screen died, well kind of, couple of days ago. I can receive phone calls now if I've headset on by pressing the "play" button, but can't if headset is not on. Also I can't make phone calls or text/email etc.

On the advice of a senior member here on xda I successfully installed ADB and after running it, I can see that my device is attached to the computer now. The question I've now is that how can I fix my blank screen?

Do I flash it with a new rom again? If yes, how can that be done? I can put files in my sd card by using an adapter. Back in January I successfully rooted and s-off my phone and flashed it with virtous Rom using a step by step method described online and it's been fine since then, but I just don't know how to flash a rom using ADB now. Also what are the chances that it'll fix this problem? Any help will be appreciated. Thanks

Can't apply OTA

Hi everyone/anyone; any help is appreciated here what I need is to apply the OTA update. I just unrooted my phone, and I'm s-on (vol+power gives the following: Vision Pvt ship s-on

Hboot-0.82.0000

Microp-0425

Radio-26.02.01.15_M2

eMMC-boot

I downloaded the OTA update and try to flash it via stock recovery. It first tells me E: can't open /cache/recovery/command (Before I do anything)

When I apply update.zip it says :

verifying update package...

E:failed to verify whole-file signature

E: signature verification failed

installation aborted. I'm now stuck pre-OTA which is a little annoying to me but obviously not end of the world. Is there a way around this? I wiped data and cache in stock recovery and that did not help.

HELP... searched a lot but still stuck at clockwork after a bad rooting attempt

Hi everyone... I have been doing a bit of searching with no luck so far. And I searched a lot but no luck in finding my stituation and don't want to screw up the phone completely...

I bought a D-Z used, Bell Rom. It showed to be S-Off, but when i checked to see if it was rooted with RootCheck, it said it wasn't. So I started the process of applying Visionary for Temprooting and then on terminal emulator, I got the error: exec format error...and, stupid me, decided to keep going. I followed the rest of the process, up to step 10 on http://theunlockr.com/2010/11/30/how...g2-htc-vision/.

But when i turned phone back on, it got stuck on the white screen with the green htc logo....

If I vol-down/turn on, i see:

Vision PVT ENG S-OFF

HBOOT-076.2000 (PC1012000)

MICROP-0425

RADIO-26.03.20.26_M

eMMC-boot

Aug 20 2010,16:51:01

HBOOT and the options:

FASTBOOT, RECOVERY, FACTORY RESET, SIMLOCK, SYSTEM INFO, IMAGE CRC

On system info it says

OS Ver.-1.34.666.5

When I put the battery in it, plugged into charger, it goes into ClockworkMod Recovery v3.0.0.5 and below the menu it says:

ClockworkRecovery v3.0.0.5

E: can't mount /cache/recovery/command

E: can't mount /cache/recovery/log

E: can't open /cache/recovery/log

E: can't mount /cache/recovery/last_log

E: can't open /cache/recovery/last_log

the phone says S-off: should I just copy some rom and launch the flashing? If so, a zip to the SD card is the way to go, right?

Or is something bad and should I attempt first loading a stock rom? (I guess not, because it says S-Off!).

have you performed a FULL wipe? are you switching between AOSP/Sense roms only performing data/cache/dalvik wipes?

you can perform a complete wipe of your device from recovery ("factory reset"), but I would recommend amazinglarry's Superwipe.

it's almost certainly nothing to do with perma-root obtained via gfree... where did you get that idea? :confused:

[G2 and Desire Z Q&A, Help & Troubleshooting] TommyDom:
I've been following the FAQ for building CM7 from source, and was at the point where I needed to pull the APK's from the phone. On my phone (T-Mobile G2) I have MS-HTCVISION-KNT20-02.apk, which I believe (from another post on another forum) to be Froyo, and the extract-files.sh is looking for MS-HTCEMR-KNT20-02-A0-GB-02.apk which I believe to be a Gingerbread version... Since I rooted the phone, and flashed the CM7.0.3 ROM, I don't have this apk. Where do I find that?

Besides not sure what I will get when I build from source, this may be the root cause of some "quality" issues I'm having using WiFi and WiFi calling (weaker signal than I expect as well as a dropped call -- all in an 800 sq/ft apartment with a decent N router.

Any help would be appreciated.

Take a look at these threads...

The one thread you mention is relevant but dated. Unless you know what you have in the PC10IMG.zip for sure and it is specifically for your hardware, its one way of installing images.

I have found the following threads very useful. Take a read through these, especially the first set of posts in each thread.

I also found this to be extremely useful as well:

http://wiki.cyanogenmod.com/index.php?title=HTC_Vision:_Recovery,_Radio_and_CyanogenMod

I would suggest that un-rooting is not necessary, and leaving s-off intact is fine. The reference they were making in the other post fro Nov 2010 is for OS images outside these radio images.

There are a lot of people that say the radio should be left alone. So, if you really think you need a new radio, do your required reading, otherwise the suggestion is to leave it alone.

Hope this helps.

Gingerbread OTA Root

I recently (yesterday) got a new g2 (my old one was replaced via warranty). Am I correct in assuming that there is no root for the new gingerbread firmware that it came with yet? I've searched around and the general consensus seems to be that there isn't.

[G2 and Desire Z Q&A, Help & Troubleshooting] Ninj:
Someone corrects me if i'm wrong but "no". Because flashing the ROM means touching phone memory. Technically though, you're not always wiping data while flashing a ROM but that doesn't seem a solution to me.

MicroSD are so cheap these days anyway ;) But i guess you were impatient to flash.

(G2 owner) I havent done this yet but is there anyway to revert to the G2 Hboot after installing the Desire Z one?.... is there a PC10IMG.zip file with the g2 hboot and tmobile radio inside? and finally if I were to install the Desire z Hboot and wanted to unroot would I have to revert to the G2 Hboot before proceeding to unroot?
[G2 and Desire Z Q&A, Help & Troubleshooting] slopes:
I'm not sure if it will work for sure either way, but here's what I think...

You'd have to store the update on a partition which won't be getting flashed, not sure which ones would have enough space, but if you could get it on there that's one step closer...

I think the bootloader only checks the sdcard for the PC10(forget rest of name).zip, so you might be able to flash it from the recovery, depending on which one you have.

Check into some of that if no one else can help, I'll try and look into it a bit more, and as I said I don't really know what will/should work, I'm just making some guesses as to how to see if it's possible.
[G2 and Desire Z Q&A, Help & Troubleshooting] karlonicolas:
I'm not sure if this will work simply because i have not yet tried it, but my DZ works fairly well with Android Commander, a windows program that you can use to control your android phone.

there's an option in the menu Phone>Flash>Update and Phone>Flash>Image>Recovery and Phone>Flash>Image>Boot, so my guess it it may work even without the sdcard.

here's the link:

and more…

- options to reboot, reboot to recovery, reboot to bootloader, power off phone

- screenshots (beta)

- tools…

hope it helps.
[G2 and Desire Z Q&A, Help & Troubleshooting] Ninj:
karlonicolas, how would that help? He needs to flash a ROM (not the recovery or the bootloader), having the ROM file in the internal memory of the phone. I don't understand your solution.
[G2 and Desire Z Q&A, Help & Troubleshooting] karlonicolas:
like i said, i have not yet tried it (flashing an img file through android commander) because my sdcard works. but there is an advertized option in android commander for flashing zip and img files:

"and more…

- flashing zip and img files"

so maybe it will help him flash a pc10img.zip or an update.zip without needing sdcard access.

by the way, i am not endorsing the software as i am unrelated to the developer, who i think did a wonderful job for making life simpler.

cheers.
[G2 and Desire Z Q&A, Help & Troubleshooting] Ninj:
Well, interesting to try but anyway, to flash a system partition, you need not to run the system, so it will restart in recovery, and as far as i know, recovery flashes only from sd. I may be wrong of course!

I already answered him in the Cyanogen 7 nightly- thread... but I'll post this here as well:

http://www.firstdroid.com/tutorials...pphire-guias/how-to-load-a-rom-with-fastboot/

That's how the rom should be flashed without an SD card.
[G2 and Desire Z Q&A, Help & Troubleshooting] Ninj:
Indeed, loading from the computer is a solution, i didn't think of fastboot one second, don't know why. Though, it means you heavily depends on the stability of your link to the computer. I wouldn't try that unless i can't spend 10$ on a microsd :)

I also commented the article you linked.
[G2 and Desire Z Q&A, Help & Troubleshooting] Kenzy-FIN:
Yup, well all those fancy fastboot-stuff are for advanced users, who really know what to expect and what they're about to do. I don't recommend that kind of stuff to newbies or people, who really don't even know for sure if their SDK is configured correctly etc. $10 micro-SD is a noob-proof solution :)
[G2 and Desire Z Q&A, Help & Troubleshooting] Ninj:
And there's no shame in being noob :)
[G2 and Desire Z Q&A, Help & Troubleshooting] karlonicolas:
yes, why didn't i think of fastboot?

my guess is that android commander is only a GUI for implementing fastboot and adb commands, but of course only the developer can answer that.

thank you for the guide Kenzy-fin. very informative.

cheers!
[G2 and Desire Z Q&A, Help & Troubleshooting] slopes:
Ya I totally forgot about fastboot too, though you'll need to get a engineering hboot on there first (which needs an sdcard as far as I can tell)

Best bet is to get a new sdcard! I have an extra one if you'd like it, class 2, 8gb...

Bottom line though, don't start messing around with your internal storage unless you *know* what you're doing, you could easily brink your phone, and it's much cheaper to get a sdcard than to replace your main PCB...

Using gfree with CM7.0.3

I have one of the original HTC Desire Z's from Bell, running on Bell's network...

I rooted a long time ago, but I only set S-OFF with gfree (no change to SIM-UNLOCK or CID), and did not install the eng-hboot, as it was not recommended at the time.

I'm currently running CM7.0.3, and would like to SIM-UNLOCK my phone and more importantly get the eng-hboot on there so I can flash a newer radio Bell has released (v 26.06.05.25 I believe) because I've still got the stock radio from back in the day (v 26.03.02.26).

I tried using gfree which I pushed to my phone to /data/local/tmp but it fails to power the eMMC and thus doesn't work...

From what I can tell, gfree won't work on gingerbread roms, so I figured I'd just start from the beginning of the rooting guide, including the downgrade, but I'm having problems...

My question is this, can I use gfree to sim-unlock and/or change the CID and/or get the eng-hboot on there? (without downgrading?) If not, is it possible by downgrading?

I've tried that as well, and when flashing the older PC10IMG.zip through the bootloader I get a "Model ID incorrect!" error and the update fails. Do I then need to downgrade with a goldcard?

Any help would be appreciated!
[G2 and Desire Z Q&A, Help & Troubleshooting] DanWilson:
But as long as you don't touch the HBOOT or radio, you're safe.

I could wipe system, data, boot, cache and recovery. Leave the phone till the battery dies to simulate some disease or something, then bring it back from the "dead" no problem.

WARNING - DO NOT TAKE ANY OF THIS ADVICE​

Well, as long as the ENG-HBOOT was installed anyway.

Moral of the story - install the engineering HBOOT if you're going to mess with everything. Sure there is a risk to flashing it, but afterwards you're pretty sorted.
[G2 and Desire Z Q&A, Help & Troubleshooting] :
Coming from the #G2root IRC channel there is a problem with the serial communication between the PC and the phone does not working. If someone that thinks they can solve the problem by going to http://www.thinkthinkdo.com/trac/project1/wiki/kgdb and/or the git that it links to it it would be very helpful. It would be even better if you discussed it with Guhl (Main dev that is working on Gingerbread root) in the IRC channel of #G2root that would be even better.

Power options

From what I understand what I have to do to add the 4way reboot options to my rom is edit the android.policy.jar. Inside of that file I find the classes.dex file. Using baksmali I can get to all the smali files that I need to edit. The file I believe I need to edit is PowerDialog.smali in the com/android/internal/policy/impl/ folder but when opening it I am lost. I have absolutely no idea what most of it means and reading through it doesn't actually give me any real clues. So my questions are first is this the right file to be editing and second what do I need to add in here to get my goals accomplished?

Edit: I attached the smali file that I think needs to be edited. Just remove the .txt

Edit 2: I just tried to swap out the PowerDialog.smali with one from cyangoen and that did nothing so back to square one I guess.
[G2 and Desire Z Q&A, Help & Troubleshooting] bsbokc:
For a lot of .apk's you can move them just fine without worrying about other files, but if you get something that won't work you will need to find the lib for that .apk it will be in the /system/lib/ folder if you have the correct lib and it is installed in the correct folder and the application still won't work correctly then you will need to modify the liscense, and that is something that I won't go into because I don't think it is allowed. But from my experience about 99% of the time the correct .apk and lib files make it work.

Noob need help

First of all, i'm a noob on android and the desire z!

on my desire z i have the stock ROM - everything stock!

but some things in the stock ROM are bothering me...

1. Data connection:

All apps are always connected to the web. consuming power and data-volume.

is there a possibility, to cancel all this crap or deinstall?

I don't need this googlemaps, amazon mp3, friendstream, latitude....crap.

Would a new customized ROM save this issue?

Are all these apps also included in a custom ROM? or clean?

2. Battery power:

My batterie lasts only 1-2 days.... ok, it's a smartphone...

but with my old Touch Pro 2 i reached nearly 5 days.

Is this also possible with a new Radio or ROM?

sure, disabling dataconnection, wlan... will save ernergy - i know.

3. Autosart of apps

If i resart the phone, all apps are started...

how to cancel?

normally if i close an app, it should be complete closed, not running in the background...?

4. new ROM

Are all the offered custom ROMs multilingual?

i new a rom in german....preferred

5. Speeding up

Is there a "safe" possibility to speed up the phone, instead of overclocking?

Sorry for some stupid questions, but on WN 6.X i have already experience with such things....and now i want to gather them on android... :o
[G2 and Desire Z Q&A, Help & Troubleshooting] dannejanne:
1. Rooting and putting in a custom ROM will help you with this. Some roms incude those apps, but when rooted you can freeze or uninstall them. Other roms doesn't even have those apps to begin with.

2. Basically no. A smartphone generally never lasts more than 2 days of use whatever you do even when rooted. If you want to have it last longer you basically can't have any apps running at all and barely use the phone.

3. If you don't want an app to run at all, root and then freeze the program with Titanium Backup for example. Then it can't start. You can completely close apps when exiting, but I don't think you should. Android handles running apps very well and in own experience if you run task killers to free memory and such the phone can become unstable instead. I almost never kill apps totally and let them be cached and the phone runs great. It will automatically exit apps if you open a new one that needs the memory.

4. No. Not all roms have the same languages. But most of them have a pretty good selection to chose from.

5. It will get boosted by rooting it and getting rid of all the apps that you don't want to have or to run in the background. Rooting and putting in CM7 for example will increase the performance of your phone. Overclocking is optional.
[G2 and Desire Z Q&A, Help & Troubleshooting] pimpmyfriedl:

Freezing means, the app is installed but can't be startet automatically?

battery issue:

android-phone also have a Radio or?

because in WinMob i had some ROM/Radio combinations which had a really good erergy-balance...

Or is this Radio the kernel in android?

With CM7 do you mean THIS?

Is this a MOD or a complete ROM?
