[Q] Error switching to Cyanogen

I have a G2. I decided to root it using the guides on Lifehacker and Cyanogens wiki. I got a temproot using Visionary, and permaroot using terminal. Everything went swimmingly. I only used download links that I found on Lifehacker and on Cyanogen's site (the same places I got the guides to root my phone) I attempted to root my phone and put CM7 on it. I backed up everything with Titanium Backup. I downloaded Rom Manager, flashed ClockworkMod Recovery to get the latest version, downloaded CM7 through Rom Manager, and attempted to install it as well as backup existing ROM and wiping data and cache. My G2 returns to the HTC startup screen and just stops.
I tried to do a factory reset, it just stops at the same area. I tried doing a factory reset from the startup options (power and down volume), nada. I tried reflashing ClockworkMod Recovery, zilch. I restored my backup from Titanium, nothing.
The phone works, I'm able to do everything I would normally do on it, but I just can't get this to work and I don't know where I went wrong or how to fix it. I have experience with UNIX based systems so I know how to work a command line to an extent and I know that part went off without a problem. I just can't figure out what's going on with it.

can you connect to your phone using adb? if you can access the shell you might be able to figure out why it's hanging.

ADB
I'm not sure I've tried ADB, any tips?
Are you talking about hooking it up to my computer as an alternative method to flash it? I had a bit of trouble with that because my computer is currently down (I just moved and don't have the room to set it up yet). I think I need a copy of the original ROM for my phone as well, if I get that I believe I can restart the whole process and do it right this time. Any ideas where to get it?

yes hook it up to the PC, even if it's in a bootloop you might be able to access the phone's system to do repairs using adb to enter the shell.
check this thread: http://forum.xda-developers.com/showthread.php?t=865685
it also explains how to use it
http://developer.android.com/guide/developing/tools/adb.html
this one got all the adb commands.
I'm not sure about the log command, but there's a way to call on the system log to see where it fails.
it's not recommended to flash an original image again, you can try to restore the backup of the original ROM (nandroid backup) if you made one...
hope this can help you.

Sounds like there is a problem with your recovery, try to manually flash recovery using flash_image instead of ROM Manager.
Use this thread for a guide: http://forum.xda-developers.com/showthread.php?t=902493
You can get the latest version of CWM (currently 3.0.2.4) here: http://www.koushikdutta.com/2010/02/clockwork-recovery-image.html just scroll down to the link that says "HTC G2"
After you flash try to manually go into recovery by shutting down the phone and powering it up while holding the volume button down, this should bring you into the bootloader menu and allow you to launch recovery.

Thanks!
I'll give that a try as soon as I can, thanks for the assistance!

[Q] I messed up my M8 (is there RUU for GPe?)

Hello,
I'm wondering if there's an official RUU for GPe that would let me restore the phone to factory configuration. I messed up my phone and while it works I observed few issues with it so far: when it first boots up for short time the launcher is accessible before the phone finish loading soft buttons and then lock screen. It's not a big deal but it decreases phone security. My WiFi no longer works.
Here's some background what happened:
I have HTC One (M8) purchased from Google Play. When I unlocked it I tried to do very minimal changes to it (install SuperSU and Xposed, I did not even flash recovery I was able to boot PhillZ Touch recovery using fastboot boot <image>, also it is S-ON as I never needed to change radios etc.) everything worked just fine. A 5.0.1 OTA came and after applying it the phone worked fine but naturally root and Xposed stopped working. I realized that after the 5.0.1 I no longer can boot custom recovery using fastboot boot <image> so I flashed latest TWRP on the recovery partition then from it I installed latest SuperSU, I also called Xposed script that supposed to uninstall it, since I learned that Xposed won't work on Lollipop.
After a reboot the phone got stuck in loading animation. After connecting adb logcat I noticed that the same message was repeating, there was more of the text, but what drew my attention was "DSEC_DMO_Token ERR: Key file does not authorize requested features. - /system/etc/soundimage/srsmodels.lic". Anyway at that point I decided to restore my 4.4.4 backup. Once restored I noticed that the phone no longer prompts me about 5.0.1 OTA and says that I'm running the latest version. I then adb sideloaded official 5.0.1 update and this is the place where I am currently. I tried wiping caches, but that had no effect.

Stuck at boot logo after partitioning externalSD in twrp

Hi guys. One of my friend has this phone. Yesterday night he did these steps:
1. unlocked bootloader (booting properly)
2. flashed twrp recovery
3. flashed su for rooting but didnt know how to update su binaries (booting properly)
4. went to twrp and partitioned external sd card (fat32+ext3+swap)
5. fixed permission
after restarting it got stuck at htc boot logo
so he gave me phone for repairing xD
here's status.
i removed sdcard.. put it in card reader.. n merged all partitions into single one just like it was before partitioning
now, i am able to see that white screen called "software status" (don't what does it called) through which i can have access to:
recovery
factory reset
simlock
check smartsd
image crc
show barcode
so basically, i need to get the installed stock htc firmware working again.
i searched forums and found European stock 5.0.2 fw. so should i flash that zip from twrp on this Indian origin phone??
or should i try factory resetting from that white screen??
basically i want to undo partitioning modifications from os and get the phone working on stock fw just like before. thanks

The "software status" white screen is fastboot. After reading your post, I think that the problem is that the device is rom-less, and I assume it happened when your friend repartitioned SD card.
Since the device is unlocked and you have a custom recovery installed, I'd go and try to install any of the custom roms posted here in the forums.
Check what version of twrp you have because there are some roms that don't run with older versions.

Thanks for replying. I'll try any custom based rom. The recovery is 2.8.1.0 (AZ development flash screen appears before twrp home screen). However, I want to know, if the European stock fm will work on this Indian variant device? Coz I tried to search for Indian / Asian fm files but no luck. How do I get exact fm matching with this one?

By fm you mean radio?
Anyway don't worry about that, because I live in Argentina and haven't had any problems with any rom I flashed.
If I were you, I'd flash this rom http://forum.xda-developers.com/showthread.php?t=3249856 because it's pretty much bugless and doesn't have any mods pre-installed.
Just out of curiosity, could you go to fastboot and post the software version number? That'd be useful in case we can find a stock backup for your variant.

LG G4 H811 bricked? How to recover?

So at first- i backed up all my data on my microsd (and actually- still have it using the LG Backup app included with the phone.)
I didn't even flash a new stock, already had a gsm unlocked device, so i did adb fastboot, unlocked bootloader, installed twrp properly, and pretty much recovered all data after first time booting into the cleared stock Android Marshmallow version (20i.)
http://forum.xda-developers.com/tmobile-g4/development/stock-h811-20i-images-kdz-flashable-t3308227
I used the tutorial above to go through this process.
Everything had seemed fine, flashed/installed root through instructions, had root, etc. Then I went through the process of flashing and getting Xposed through multiple tutorials like this:
http://forum.xda-developers.com/xposed/super-alpha-posted-permission-xposed-t3072979
The device was now stuck in a boot loop and I could only get into TWRP recovery. So I downloaded the stock flashable zip and flashed it and now- nothing. the screen was black upon reboot. I tried plugging it in, computer is making confirmation sound like a usb device was recognized but nothing pops up. How exactly do I unbrick and get back to stock? I have all my main data still backed up on my microsd.
(Also, I apologize for this being in the wrong forum since I am new. Please redirect me as you please.)

LG H815 stuck on boot

Hello
I tried rooting my LG H815 and it didn't go so well.
I managed to successfully unlock the bootloader following the steps on the LG developer website.
I downloaded SuperSu (UPDATE-SuperSU-v2.46.zip) and placed it in the internal storage of the phone.
Afterwards in order to root the device, I booted into TWRP with "fastboot boot twrp-3.0.2-1-h815.img".
In TWRP I flashed SuperSu. After it finished flashing I rebooted the device. After it attempted to start up again, it froze at the LG logo. I waited around 10 minutes and figured it's not successfully boot.
I removed the battery and tried to fire it up again, but it didn't get past the Logo screen again.
I managed to send "adb reboot recovery" to it, but all I get is an image of a little dead android. I guess this is because I only booted TWRP and did not flash it.
When I get it in fastboot mode, "fastboot boot twrp-3.0.2-1-h815.img" does work anymore now. I just says < waiting for any device >.
I managed to get into default recovery with power up + vol down where it prompted me to do a reset by responding Yes twice, but after it rebooted, it still got stuck on Lg logo.

If you cannot get to the recovery then follow these steps:
i) Make sure you have the LG Drivers installed from here: http://oceanhost.eu/e4h2px4e0hkd/LGMobileDriver_WHQL_Ver_4.0.4.exe.htm
ii) Download the LG Bridge software from here: http://www.lg.com/us/support/product-help/CT10000025-1438110404543-preinstall-apps
iii) Remove the battery and reinsert it so the device it is fully off.
iv) While holding the up volume button, insert your USB cable.
v) You should enter download mode. Go to the Software Update tab of the LG Bridge. It will say connecting and then should say your device is up to date. Click on the recovery text on the bottom right and then follow the instructions. The software will download the system image for you and this is roughly 1.6GB so make sure your firewall doesn't block this connection.
This shouldn't delete your data (no guarantees) but you will have to grant app permissions again and reapply any changes to system files e.g. root, viper4android, xposed ect.
If you have problems try this method instead:
http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
If successful and you're brave enough to try again. Then make sure you actually flash TWRP. I think you are right in that you only booted TWRP .
You can follow my TWRP/root guide here: https://forum.xda-developers.com/g4/general/howto-complete-guide-to-unlock-twrp-t3370003
Good luck

Thanks a lot for answering.
LG Bridge wasn't detecting my device. I don't remember if I was in download mode when I tried this, though. I might've not been.
I didn't know how to fix it and asked a friend for help. He managed to flash the h815 stock firmware through some Taiwanese/Korean flash tool (Edit: It was LGUP and he flash a kdz file with the stock firmware).
I followed a similar guide to yours when I flashed SuperSU from TWRP, except I didn't install twrp permanently after booting it from the .img file. I thought it was not possible to install twrp if the device is not rooted first.
I still kinda want to root the device since I voided my warranty by unlocking the bootloader, but I'm afraid I'll break it again if I use the same method.
Edit: Managed to successfully flash twrp. Booted into recovery again after rebooting system. I am now creating and saving a full backup with TWRP. Will try flashing SU again afterwards.
Edit2: I flashed SU after properly installing TWRP and it worked like a charm.
