I need help understanding why I'm stuck in reboot loop with my EVO 4G.
I originally was trying to root the device using unrevoked3 but getting the ERROR "Backup CID is Missing" message and unable to proceed. I followed the instructions at http://androidforums.com/evo-4g-all-things-root/194918-rooting-dummies.html which talk about troubleshooting this. It talks about going into recovery mode to see if I've lost the recovery mode which I did (black screen with phone and read arrows). It says to reboot but I was unable to so I unplugged the battery.
Since then I have been stuck in a mode where the device boots but the sdcard is not recognized and upon completion of boot up it shuts down and vibrates five times. I did a bunch of research last night on understanding what I thought I needed to do alleviate this. My thought was since I was stuck without a recovery image I need to flash new one. At this point I'm fine with not being rooted with all the trouble I've had.
I downloaded the latest stock recovery rom (3.70.651.1) from http://androidforums.com/evo-4g-all-things-root/259446-clockwork-amon-ra-pc36img-files.html and pushed it to my sdcard under the name PC36IMG.zip (with two files .info and recovery.img). I restarted my phone via HBOOT and it sees the zip file, reads it in, goes to checking and then does nothing (back to HBOOT screen). I don't get what I'm doing wrong. I also tried getting the stock image from http://forum.xda-developers.com/showthread.php?t=874091 but I can't seem to open the firmware.zip file to try that recovery image.
Again I just want to get back to stock ROM and recovery files now. Any help would be greatly appreciated!
OK so I put the newest nightly for CM10 onto my Nexus and it has been a while since I did a clean install so I performed a full wipe, but accidentally wipped the sdcard as well. Soooo, I have no update on the phone to flash via recovery and I wiped sysetem, data etc.... so I got nothing.
I know I can either flash the update via fastboot, or send the update to the sdcard via abd but for the life of me I cannot remember how to do either. This is my only phone and im home alone with my two kids right now so I need it fixed asap. Everything I have found doesn't seem to be working for me. I tried
while in recovery mode hook phone to computer via usb, then open cmd and "abd push c:\android\platform-tools\update,zip (I renamed it to this) /sdcard
No luck there.
I also tried from fastboot mode :fastboot flash update update.zip" Thought I had success here because it was sending the date but the phone still wouldn't boot past the "Google" screen.
I know someone on here has the answer for me easily, and it would be much appreciated if anyone could help me out.
Thanks in advance

Try ...
adb push c:\android\platform-tools\update,zip /sdcard/
or
adb push c:\android\platform-tools\update,zip /data/media/
fastboot flashes .img files
Ok so I have figured something strange out here. I thought that I had accidentally wiped the sdcard. I thought this because in recovery I select "install from sdcard" and then "choose zip from sdcard". Then I see " 0/ " It didn't even occur to me that everything was in there because that has never happened before. I would love to just restore a nandroid I have saved, but when I select restore in recovery it tells me that no files are found, because they are in "0/sdcard/". If I navigate there in recovery I can see the nandroid but CWM cant find it. Any ideas on this??
Stuck in a bootloop. Here's my story.
Updated to 4.4.2 earlier today.
Tried to root my Nexus 7 later after the update. Here's what I did:
rebooted into bootloader with adb (adb reboot-bootloader)
unlocked the bootloader with fastboot (fastboot oem unlock)
flashed clockworkmod using fastboot (this is the file i downloaded and flashed: -http://download2.clockworkmod.com/recoveries/recovery-clockwork-6.0.4.3-flo.img)
rebooted into recovery
selected "install zip>choose zip from sdcard" (trying to install supersu.zip file that I had loaded onto the internal memory)
Here's where I ran into trouble. After selecting "choose zip" nothing happens, and a message shows up on botton of the screen that says "E: Can't mount /sdcard"
So I can't install anything from clockworkmod.
I rebooted into bootloader, tried to re-flash using fastboot - "device not found"
I tried to reboot the device into android - bootloop animation
I tried wiping data, cache, factory reset, dalvik chache, etc from recovery - still getting bootloop animation
Any ideas?
Ok, I wiped/deleted sdcard data from clockworkmod and I managed to get it to boot.
That's deadly but I still don't have root, which was the point of this in the first place. Anyone know where I went wrong?
Strange. I did pretty much the exact same procedure and it worked for me.
Sent from my Nexus 10 using xda app-developers app
So, I flashed TWRP.
Tried installing SuperSu from there. This worked slightly better than Clockworkmod Recovery, it at least could read the internal storage, and allowed me to select the supersu.zip file. But I get the following error when I try to install it:
E: Unable to open zip file
Error flashing zip 'sdcard/Download/UPDATE-SuperSU-v1.80.zip
Not sure what's happening here.... May have to do with the 4.4.2 update? Maybe I'll try flashing the 4.4.2 factory image and then retrying the above steps.
I also did pretty much the same. I had a new Nexus 7 2013. The very first thing I did was to update to 4.4.2 through OTA before I went to rooting procedures:
Unlock bootloader (data was wiped because of it)
Flash TWRP
Flash superuser.zip file through TWRP
Everything worked fine.
So just as the title says i decided to root my n7. Everything seemed to go smooth until my nexus 7 was stuck on the boot animation screen for about 20 minutes. I tried doing a factory reset in TWRP and it said wipe failed. I decided to flash CWM instead and do a factory reset but i couldn't. It said error mounting /data. I'm not sure what to do googling around didn't seem to work.
TWRP gave me a message saying SU is not installed after i installed the recovery so i clicked instal SU. I'm not sure if that contributed to my problem or not. Any help would be greatly appreciated.
Ok so i figured this out.
So for anyone who ever gets into an endless bootloop with the inability to wipe data you need to do the following.
1. Download the latest Factory image from google.
2. Exctract the files into your platform-tools folder an run the "flash-all" command this video illustrates it perfectly http://www.youtube.com/watch?v=bsss9e71bKo
3. And you're done! hopefully this helps someone out
Can't install any ROMs on G2.
Had CWM 5.0.27, I think. Couldn't install any of several ROMs. Installed CWM 6.0.4.5. Same outcome.
Aroma installer always stops at "Symlinking..." after extracting files.
Says "set_perm: some changes failed" and Status 7.
What am I doing wrong?

Well as far as I remember, the new roms were better to be installed with 4ext Recovery, because the CWM had some problems working with ext4 filesystem. Try the one I have on the web site below, that should fix it for you.

Thanks, but the zip didn't work. Put it in sdcard root and tried several times with CWM Touch 5.8.1.0 -- installation failed, every time.
I've since gotten CM10.1 and Mimicry to work with CWM, but I'm struggling with one ROM in particular no matter the recovery: coolIOS, a 4.0.4.
Tried to install it with CWM 5.0.2.7 and got the error described at top.
Tried with CWM 6.0.4.5.
Tried with CWM Touch 5.8.1.0.
Tried with TWRP 2.6.3.0.
Same error, every time. Redownloaded the ROM, but same. I'm really at a loss with that one. It worked fine on a previous G2.

I meant the only 4ext install zip I could find didn't work.
Downloaded the apk from the site and got "Cannot open file".
Yes, Unknown Sources is checked.
Thanks, anyway.
EDIT: Got 4ext working, but still no help. Had to extract the .img from the install zip, install Mimicry ROM, and use the Terminal Emulator to flash the .img. That got it working, but it only boots in safe mode. Says it can't read the cache partition, and also says this:
"If you changed hboot you should choose to format all partitions (except sdcard)".
Formatted all partitions, rebooted recovery -- still safe mode. Still says it can't read cache.
Starting to think some of the physical memory is corrupt.
But if that's the case, why do other ROMs work? Or does someone else see another plan/fix/anything here? Thanks.

There is no install zip on my pages, just zipped image which should be pushed in via Fastboot. You are perhaps doing something terribly wrong my friend.
What you need to do can be achieved by several ways:
- Rename recovery.zip to PC10IMG.zip put it into your /sdcard root and start your phone to recovery (hold Vol-Down and Power to start recovery system)
- use adb to push the image to the recovery partition
- or the easiest could be to check this one: http://www.4ext.net/install.pdf

Perhaps I was unclear. I downloaded your zip and renamed it PC10IMG.zip and put it in sdcard root and started to recovery, but that did not work. I thought it would work, since the phone showed the "vertical progress bar" as if it was about to change recovery, but I didn't get the prompt to "Update recovery?" that I usually see there. So nothing happened.
I also tried to download the 4ext apk directly from the site onto my phone, but after downloading the apk, phone said "Cannot open file."
Instead, I got 4ext working by downloading the zip in the 4ext forum zip. It contains an .img that I flashed in Terminal Emulator, which got 4ext working.
Once I booted to 4ext, it said it could only load in safe mode because it couldn't read the cache. It advised to wipe the cache, so I wiped everything several times, but it still only loads in safe mode.
I'll try your zip method again, and I thank you for the assistance. I just don't get why five different recoveries work on some ROMs but not one that worked fine on a past G2.

SOLVED: Helps if I read the instructions. Thread for that ROM clearly says to have Desire Z hboot; I had G2 hboot. In all the years of using a G2, I've never had to switch hboot and was unfamiliar with it. If anyone else has same issues as this post, might try installing the Virtuous Team's PC10IMG.zip and read up on it at the Hboot thread. Thanks to all who beared with my lack of knowledge.
