Completely lost, won't boot, confused :( - Nexus 7 Q&A, Help & Troubleshooting

right so i have twrp 2.2.1.4 and made a backup, flashed cm10 (no gapps), tried to boot, nothing but a black screen. so i held the power button and vol down to get into bootloader but idk what to do from there because clicking "recovery mode" sounds like something other than a boot into twrp and fastboot commands aren't working. can someone tell me how to get this working again?
also when i tried restoring a backup via twrp before i wasn't able to boot cm it would just reboot twrp and not restore...
Edit: nvm i fixed it. i thought recovery mode would put it in something similar to dfu mode on ipods but clicked it anyway and got to twrp still can't restore my backup tho...
Edit2: ok now found out that 2.2.1.4 was a bad release. went back to 2.2.1 and all is good

[Q] ClockworkMod Recovery 5.0.0.1 flashed from ROM manager failed. trying again

I just got the new CWM recovery update through Rom Manager today, and it said it was successfully flashed, but the phone only hangs on the HTC logo when goingto recovery. I can still do fastboot and boot to Android tho, so I'm now gonna try to figure out how to get my recovery back before something bad happes xD
anyone have advice or know where I can download a standalone copy of CWM 5.0.0.1 for G2?
Wish me luck I'll keep updating as things progress
okipokey, solved my own issue. Just had to reflash back to an older recovery and try again a couple times before it stuck.
Time to test out the new recovery!
I decided to flash the upgrade as well. The flash went perfectly. However, I couldn't boot into recovery while within Android. I had to power off and boot into the bootloader and then select recovery... Whenever I tried to reboot to recovery via the Android UI, it restarted and hung at the boot splash screen.. It didn't even work if you selected the option from the ROM Manager itself... I rolled back to previous version as well and its working again. It may be a bug... Early adopters nightmare....
Same here just reinstalled the new version and it worked second time round
must be a bug they havn't quite worked out. Next time I'll do a fastboot flash instead for a low build number.
First time I flashed I tried it from a battery pull through HBOOT and it still hung. Reflash to 3.5 and then back to 5.0 fixed it like you guys

try just reflashing version 5 I had the same problem,but rebooted the phone reflashed version 5 from the rom manager and now is all good
I just sent the dev a comment about it on his Google+
maybe he'll have a fix out soon
Nice one, seems a "double flash" fixes it have just tested 3 or 4 times,seems to be working
yessir, seems to me that if it's a bug its really minor. I can see this being a problem if someone accidentally screws up something on their phone right after flashing the recovery, but not very likely and they'd still be able to reflash through fastboot
Seemed to flash the new version ok. But then, when trying to boot into recovery for the first time, the phone hung on the HTC logo boot splash. Pulled battery, and booted into recovery ok after that.
that's interesting that some of you didn't hang after the battery pull while mine did. Maybe it depends which version we're upgrading from?
stuck at htc
hey i also had this problem and i can't get my g2 to boot up at all. It hangs at the htc screen. I don't know how to fix this issue as i was trying to restore a backup from recovery right after the update. i can't get into recovery or anything else...all i get is the htc screen. Any ideas how I can fix this?

found this
-From Mr.Dutta via G+
I've just finished releasing updates to a bunch of devices to ClockworkMod Recovery 5.
Major changes:
Backups now use tar over yaffs for everything except mtd partitions. Backups got way faster.
Backups now preserve the filesystem type at time of backup. Restores will restore the appropriate filesystem type at restore.
Please update to ROM Manager 4.4.0.3 or higher and try out the new recovery!
Troubleshooting:
Flashing issues: If a recovery does not flash properly, enable erase recovery in settings and try flashing it again. Recovery flashing can be finicky at times.
Bugs: Report them to me! You can always revert back to the older recovery too from within ROM Manager!
So far no issues here while playing around.
my issue is i can't get back to android at all now. i went into rom manager to restore a backup and was told there was an update, then it reflashed the recovery. When i tried to restore my backup it froze and i have not been able to get past the htc screen at all.

can you get into the HBOOT?
pull the battery, put it back in, hold the volume down button and then hit the power button. you should come to a white screen with some options
In the case you want to update your recovery using fastboot method, heres what you'll need:
CWM 5.0.0.1 for G2 (Vision)
HTC Sync drivers
ADB fastboot from Android SDK
Make sure your phone is all the way off by pulling the battery. Get into the HBOOT by holding down the volume down button and then hitting the power. use the volume keys to navigate and the power button to select. Choose "FASTBOOT"
Rename the recovery that you downloaded from CWM to "recovery.img" and put it in your ADB and Fastboot folder
plug your phone into your computer and pull up a command line for your adb/tools/ or adb/platform-tools/ folder where you should have ADB and Fastboot.
under the command line type in:
fastboot devices
<list of devices>
If you do not see your device make sure the cable is plugged in and your drivers are installed. if still nothing try a different cable til you get it to be recognized by the computer.
Once it's recognized do:
fastboot flash recovery recovery.img
when its done:
reboot
I flashed through ROM manager. On suggestion, I checked the box for "erase recovery - recovery will be erased prior to flashing". On first reboot to recovery it sticks at HTC screen. Pulling battery and vol. up+power then entering recovery the 2nd time works just fine.
Hope this helps.

[Q] Stuck in recovery boot loop...?

While using the PA Updater app to upgrade my rom, the app attempted to reboot into recovery to run an openrecovery script. While doing this, I believe it set my "reboot mode flag" to recovery.
The tablet boots with the Google screen and then shows the TWRP splash (I'm on version 2.6.0.0), then it reboots and starts again.
I am able to get to the bootloader, but even if I press start or recovery mode it reenters the boot loop trying to get into recovery. In the bootloader was where I saw the reboot mode flag set to recovery. Is there a way to use fastboot to remove that or am I just going to have to do a wipe with fastboot?
It happened to me once. I pushed the power button for 60 seconds as it supposed to do a kind of battery pull, and it worked.

I've done this twice to my nexus now and I think I found a reliable way to restore to running condition. YMMV
1)Boot the nexus into fastboot (power and both volume keys) when you power up.
2)Attach your usb cable from the PC (or MAC I guess, dont have one to try)
3)start WUG Nexxus Root Toolkit. 'Launch' advanced utilities.
4)Test your fastboot with Quick tools. check the button at Fastboot-Bootloader and click 'List Devices' if the box that pops up is empty then fastboot isn't working (I can't help you there and it must be working to continue).
5)If fastboot shows a device then go to "Boot Temporary" and click 'Custom Recovery'.
6)I selected 'Touch TWRP' but CMW may work as well. This will reboot you into (temp)TWRP and from there you can force a reboot that will reset the 'Recovery' flag that has locked your bootloader.
7)Give it a few minutes (be patient for 5 minutes) and hopefully you reboot to where you were prior to this mess.
Long time lurker and couldn't fix my fails without everyone here.
Thanks to all.

I had the same thing happen to me (though i updated from stock 4.4 to 4.4.2 [and i had twrp installed]). I tried reflashing to stock recovery and a few other things but same problem, it kept booting me into stock recovery. I know this is going to sound crazy, even stupid, but just letting it sit there for 5 minutes (at the stock recovery screen) let it work... I was searching for more things to try and it just started booting.... Checking the bootloader again showed the reboot mode flag set to none.

I guess mine worked because I was still on stock bootloader and adding TWRP was an important key but the 5 minutes seems to be the solution after all the rest.
recovery boot loop:- Is coz, one of your partitions would be facing problems while mounting.. So Wipe the Partition and Format it with Ext-2 file format. and reboot the Mobile. Then it'll stops rebooting.
Do you have a Samsung device?
Be warned - there is no such thing as fastboot mode for most Samsung Galaxy devices - you'll be wasting your time doing this and typing "fastboot devices" for many hours!
If you have problems with your recovery, it works to just reflash the CF-autoroot kit, which happens to flash the cache partition too. My problem was similar to the OP's - a bootloop with TWRP's obviously buggy OpenRecoveryScript, which was installing a ZIP file over and over again.
If you flash the CF-autoroot specific to your device, TWRP will be gone, but the phone will boot normally again - with all your data on it - hooray!
Then you install TWRP or CWM recovery as you did originally.
Stay away from OpenRecoveryScripts! I'll be installing a ZIP file in the traditional, manual way from now on, from an external SD card so I can remove the card if I get another TWRP boot loop.

Security error after recovery update

I have a d802 . I had cloudy1.3 and twrp 2.7 installed with autorec. I tried to update it using
dd if=/sdcard/recoveryfilename.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery
(from twrp page, with the latest img file).
But I coudn't access recovery, some error about security. Then I shutdown my phone and then it booted fine into system. I retried to access recovery but nothing.
So I decided to return to autorec, I installed it, I clicked "Flash Recovery" and now my phone doesn't boot in any way.
It show "lg security error" and then shutdown.
I can access download mode. Is there a way to fix my phone without deleting everything?
I'm sure the problem is the recovery, I was messing with it, can I bring my phone back and don't delete my configuration, photos, apps?
Thanks
I'm so happy!
I did it!!!
I managed to boot into recovery with the usual combination of keys (with the method that ask you if you want to format, but then you press power and it boot into recovery).
From there I saved everything using adb pull (Just in case). Then I dirty flashed Cloudy 1.3 and my phone is back !
I hope my experience can help someone

a6000 shut down during MIUI flash, won't boot into recovery

Hey guys I was trying to flash MIUI 8 on my a6000 lenovo. Bear with me because I'm new to this so I might have screwed up.
Rooted and installed TWRP perfectly. Phone was running kitkat.
I then, through TWRP tried to flash MIUI 8 from http://forum.xda-developers.com/lenovo-a6000/development/rom-miui-7-lenovo-a6000-a6000-t3355692
After first swiping right to install the zip, i got an "error executing binary in zip" error. Wiped dalvik,etc. again and tried again and then I got a MD5 file not found "warning". It was not in red letters and after that message there was no progress bar or anything and the phone just stopped responding. I assumed it wasn't working and few minutes later took the battery out. After trying to boot again it would give me the "mi.com" boot screen (not the default lenovo I used to get) and won't boot into neither recovery nor normal mode. (for recovery boot I'm trying holding both volume buttons and the power button at the same time. perhaps that is different now?)
I'm guessing the flashing was going on and i interrupted it. How can I fix this?
Update: It boots into MIUI now however pretty much nothing works as expected. It wont even go into settings. Recovery still seems botched and i cant boot into it.
TLDR: Recovery broken cant boot into it. Can boot into MIUI with very limited capabilities. Cannot select USB debugging and "adb devices" won't find the phone. What can I do?
Alright nevermind guys I managed to fix it. for anyone wondering or having the same issue, i tried many things but what I think worked is this:
Turnt on my phone in fastboot mode (hold volume - and power button) , connected it to the computer and used command "fastboot flash recovery recovery.img" to flash the old TWRP i had on my computer. After that I managed to boot my phone in recovery mode and reflash the rom properly. The weird thing is, my phone could not be recognized by the computer and "adb devices" gave me nothing back so I thought using any fastboot command wouldn't work. Oddly, it did and it flashed TWRP back into my phone.

Cant boot into TWRP

Hello, ive unlocked my bootloader on my h870 and ive flashed twrp. when ive just flashed it i was able to boot into twrp but now everytime i try to boot into it it wil wipe all my data with the stock lg recovery mode can someoneone please help me? Thanks! Just got the phone a few hours ago
You have to install a custom rom or root to make twrp permanent, if you don't do that it will install always after the first boot the stock recovery.

When you have flashed twrp, you do the buton combination to enter twrp, if you fail to enter twrp a the phone boots into system the stock recovery will be reflashed so you have to reflash twrp.
Try making these:
When you are in the bootloader after flashing twrp press button down+ power button. When the screen turns off quickly stop pressing power button and quickly press again until the lg logo appear.
When the lg logo appear stop pressing power button, quickly press again and stop pressing the power button and press again quickly until you see twrp logo.
These method works for me for booting twrp easily
The stock recovery appears but you have to select the factory reset option and it will boot into TWRP

Unfortunately still not succeeded after trying all the solutions i've found here
Hey, i have the same Problem, my TWRP broke, i can't boot into recovery and my Device ist not listed in fastboot mode. Can someone help me out?
I get the ring in windows when i plugin but its not recognizing.. Can someone pls help me out?
Okay, I'm going to try to explain it, and see if I can succeed where others have not.
You install TWRP by booting to bootloader and using fastboot to push a new recovery:
Code:
fastboot flash recovery twrp.img
It seems like you accomplished that successfully. The next step is to immediately boot to recovery; do not boot the phone to system first. You will get the factory prompts for wiping data, but it will not actually wipe your data this time. Instead it will boot to TWRP.
Now, while you are in TWRP, you need to either root (flash Magisk) or install a custom ROM. If you do not, your next boot to system will remove TWRP and restore the stock recovery. If that happens, then the data-wiping prompts the next time you boot to recovery are real and the phone will wipe. So you MUST - must must must - root or install a custom ROM while you have TWRP up, in order for TWRP to persist.
If you have already experienced this problem, you need to start over at the beginning; flash TWRP again, and then follow the rest of these directions.
Maybe this will help clear up the problem for you guys.

Oh my god, i really really thanks for your reply, you're so fre*king good. U made my day.
Guys a little help
I only manage to see the TWRP welcome screen and the the phone automatically reboots to system
I can't get to see the TWRP menu at all!!
WTF is going on?
I have repeated the process many many times and always the same. What i am missing here?!?!?
me too when it boots in twrp only showing logo then it reboots in system what are wedoing wrong?
Got the same problem. I unlocked Bootloader, checked if unlocked (yes). After flashing TWRP i see the TeamWin Screen and phone boot again. There is no TeamWin Menu.
A try with an older TWRP-Version and flashing via fastboot with another PC does not work too.
Anybody an idea?
Did you guys manage to fix it?
Matt.

With 3.2.1.0, 3.2.2.0 and 3.2.3.0 it only briefly shows the TWRP screen and then boots into system anyway.
With 3.1.1.0 the key combination to boot into TWRP as with the other versions above simply doesn't work, again it directly boots into system without even showing the TWRP screen.
I'm stuck with a resetted phone because of this bull****, because some instructions said "oh, the reset dialog will not really reset your data..." - yeah thanks for nothing, buddy.
So what now?
EDIT: I got it working using TWRP 3.1.1.0, but the same version from the OFFICIAL site didn't work, as I described above.
The only 3.1.1.0 TWRP that works with my phone is the one from this Link: http://downloads.codefi.re/rashed/g6/
(which is linked ... somewhere here in the Forum, don't remember which thread)
