[Q] Problem with TWRP - Nexus 7 Q&A, Help & Troubleshooting

I installed twrp a couple of weeks ago and all seemed well.
Tonight I needed to get into recovery to flash the system update, and it seems my recovery isn't working, all I get is the android on his back with an exclamation point over it. I then used wugs toolkit to unroot my device and flash the stock image.. which was successful, but still I have no recovery. As a last resort, I used the toolkit again to re-root, this time ticking the box to enable the installation of cwm, when it it got to the point of the process that cwm would be installed, it said something along the lines of "opening twrp" .. it finished it's process, I'm rooted, but without recovery.
I'm at a loss. Is there a way to force cwm or something?
*disclaimer*
My device was plugged into my pc while attempting to get into recovery.

I just went ahead and reinstalled twrp, and it let me boot into recovery to install the the update zip. I'd still like to know why twrp failed in the first place, it's not a good feeling knowing that your recovery might not be there when you need it.

Unlockr didn't totally work. Did nandroid restore. Not sure where I am now.

I tried yesterday to one-click root my MT3G following unlockr.
Got the Amon-Ra recovery on there, but it hung on the green MT3G splash screen when I tried flashing cyanogen 4.1.11 .
Waited like over 20 minutes. So I took out battery, and tried to boot again. Same thing. So I rebooted into recovery and tried flashing ROM again.
No matter what ROM I tried, I got a "E:Can't open /sdcard/update.zip (bad)" message. (I redownloaded ROMs from different sources given the message thinking maybe they were bad or incomlplete, but nothing worked).
I finally did a nandroid restore.
Now I'm not sure where I am. Given that I restored my stock nandroid backup, my understanding is I'm no longer rooted. Though, I am still able to boot into the Amon-Ra recovery. which I thought would have not still been possible. I downloaded better terminal and tried typing "su" but it wouldn't let me continue, so that confirms not rooted, right?
Do I run the recovery flasher app again (which is still on the phone), and reflash a recovery image? Or should I delete the app and redownload the recovery flasher apk.
Just not sure how to safely retry.
You need to provide more details about your process. I actually unrooted mine previously done with Cyanogen Recovery and rerooted with same instructions on that site only this time with Amon Ra recovery image without problems. In my case I wanted the option of formatting partitions. Maybe you should try Cyanogen stable Rom first, like 3.68.1 version. I had an issue with 4.1.11.1 after I partitioned the card so I did 3.68.1>4.0.4>4.1.11.1.

[Q] Stuck trying to root nexus 10

This isn't my first android root but I'm stuck. I followed the video for rooting my Nexus 10. Got stuck in a boot loop but was able to flash cwm but still in boot loop. I tried doing the factory reset and now cwm is gone too and still stuck in boot loop. I tried reflashing cwm. When I try to access recovery I get the red triangle with ! on it. And I'm stuck in boot loop. I went here and tried to reflash recovery.img and no joy. Still no recovery access and no boot. ((
accidentally posted this in the samsung nexus forum #whoops
Boot back into recovery and press all 3 buttons (power, vol +, vol -) simultaneously until the menu comes up. The timing has to be very exact so don't worry if it takes 10+ tries. Then select factory reset and it should boot up properly.
I never could get CMW to stay. So I flashed TWRP as the recovery instead. Also follow wireroid advice about getting out of boot loop. If you want to SEE that method, check out the rooting N10 vid on youtube by qbking777.
some progress!
Ok I got back into the tablet with wireroid help YAH!!
I have a system update pending but when I tried to install it I got the red! with 'no command' ... after a near heart attack I did the factory reset again and got back to where I was before.
Now I need pointed in the right direction. So right now I'm unlocked but that's it. I have no custom recovery and presumably no su access because all I successfully did was unlock the bootloader.
I downloaded the nexux10 toolkit. Do I need to flash a recovery first? Do I try CMW again or go with TWRP? I've only used CMW in the past.
Do I ignore this Jelly Bean system update for now??

Try this toolkit by Wugfresh. http://www.wugfresh.com/nrt/
It's what I used and I went from locked and stock to unlocked, rooted, and with TWRP as my recovery in less than 15 minutes. I unlocked and rooted my GNex the "old-fashioned" way but wanted something easier for my N10.
Also, here's a YouTube video from QBKing77 walking you through the process using the above toolkit. https://www.youtube.com/watch?v=YtLvlrUDB04&feature=youtube_gdata_player
Since you're already unlocked you should be able to just skip to the part where root and a custom recovery are flashed (you'll end up with TWRP but you can always download ROM Manager and flash ClockworkMod if that's your preference).
Good luck.
I ran MSkip toolkit and it repaired everything. I got a failed on renaming my recovery images so my stock recovery images are just gone I guess? Anyway I'm good. Rooted and repaired thanks to Skips toolkit.
Thanks for all the help!

[Q] How do I restore device after failed OTA 5.0.1 update on rooted N4?

Hi folks,
I recently rooted by N4. It was running Android 5.0.
I also have MultiROM installed, with CyanogenMod installed as a secondary ROM.
I didn't realise I couldn't apply the OTA updates to the stock Android system (my oversight), and I allowed the device to download and (attempt an) the recent 5.0.1 update from Google.
When the update attempted to reboot the device, I could see in the terminal data that popped up, that it failed.
After that device now gets stuck in the booting stage with the little coloured balls drifting around.
I continued to use my phone with the secondary ROM (Cyanogen) for some days until I had time to sort this out.
MY ATTEMPTED RECOVERY
I read that ordinarily on a rooted device one would manually apply the various image files from the full 5.0.1 package.
So, following instructions found here: http://forum.xda-developers.com/nexus-6/general/guide-flash-factory-images-nexus-6shamu-t2954008
Using method two (long method).
... In fastboot mode I flashed the system, boot, recovery, cache (after clearing cache), radio images from the 5.0.1 stock image.
At first I didn't flash the bootloader (as I wanted to maintain the multiboot loader I had installed) nor the user.img (I don't want to lose my user data). I read this should work. But it didn't.
When it came to booting into recovery mode to finish the process, an android icon with a ! warning on it would appear, and I could not do the recovery.
So, I have since flashed the bootloader also. That didn't change much, except that my dual-boot boot loader is now gone, and the device is still not recoverable.
Is there something I am not doing correctly? How can I recover this device so that it has 5.0.1, my existing user data, and my existing dual boot bootloader?
Cheers,...
May have solved it...
I'll post another update in a moment. Posting this just in case someone starts responding to my question in the interim.
After further fiddling around, I may have resolved this issue. I've managed to get it into recovery menu, rebooted from there, and device is now in "Android is updating" mode. Looking good.
Will post new message soon as to whether this was successful or not.
Issues continue
So, after the device booted a screen appeared for a fraction of a second, that appeared to be the screen for selecting system language (as per what happens when a device is first run after a clean install). But the screen almost instantly goes black except for the little network icon and battery icon and time in the top right of the screen.
If I use the power button to lock the screen and again to activate it, the screen very briefly flashed up the language selector, then goes blank again.
So... it seems something odd is happening after applying the 5.0.1 file.
Any suggestions?

Well, this is what I resorted to doing. And it worked. Phone started and was as new. Of course, I lost my user data which is a ****. I did pull the SDCARD content over ADB, but am not sure how I'd go about pushing it all back on, into right locations, etc.
BUT—and it's a BIG BUT—when I re-rooted it and applied SuperSu, it couldn't be put into recovery mode any more. It would keep running through the SuperSu install process each time I'd attempt to go into Recovery.
I ended up ignoring this, and installing Busybox (with Play) and SuperSu.apk (via Play). But the SuperSU apk would keep saying its files needed to be installed/updated.
I forget the exact mess that unfolded, but eventually (after installing MultiROM) I could boot the phone as it would ALWAYS go into (custom) recovery.
So I starter the whole process again, with another clean install of 5.0.1, and yet now it is stuck at the bootloader (the little swirling balls screen).

Try a full wipe from Factory Recovery, and see if it will fix the bootloop.
Bootloop no more...

After many tedious hours of messing around with this beast... there is life beyond the bootloop.
Back to a stock install.
So, now I am wondering why the SuperSu/Root process didn't work on my last round on this.
The SuperSu installer would kick in EVERY time I went into Recovery mode, and would then reboot the phone. This made it impossible to do things with ADP because I essentially couldn't get into recovery mode. I wanted to push through some of the stuff I pulled using ADP before I wiped the phone previously.
I installed MultiROM (which includes TWRP [is that what it's called] recovery system. BUT then go stuck in a Recovery loop.
Not wishing to repeat that fiasco... does anyone more knowledgeable than I (not a difficult status to achieve) have any suggestions to what might have caused those issues?

Lg G2 LS980: Having Problems After Trying To Flash CyanogenMod 12.1

Sprint LS980 in an odd state after trying to flash CyanogenMod 12.1
Ok... so I got two of these Sprint LG G2's. I was able to successfully flash the first one with a minimum amount of problems considering I was just learning how to do it.
This second one is a problem though. Here's what I did:
I tried to root but it could not due to the version of the Sprint firmware on the phone. I did the TOT stock flash to get it back to stock. That worked fine.
Then I was able to root it via ioroot. Once rooted, I installed FreeGee and tried to install TWRP, that didn't seem to work, so I installed CWM Recovery. I did option two on this thread to try to get the loki stuff installed using openrecovery-twrp-2.6.3.4-ls980. That "installed" and I was able to boot into it. I installed cm-12.1-20151125-NIGHTLY-ls980 (same one I used on the other phone). That would not install via CWM and gave an error about not being able to lokify (or something like that).
So I said, OK, I must have done something wrong, so I tried to redo stock flash again. That acts like everything works fine LGFlash does it's thing (using LS980ZVA_01.TOT), but the phone boots up and does not seem to finish the install process. The LG logo comes up and not the Sprint screen that I would expect. I can do this over and over again and the results are the same whether I let it sit for an hour or 10 minutes after flashing. So now, the phone boots, but I can't do anything with the touch screen, and will then go into a reboot loop (getting into the OS but rebooting shortly after). I CAN get into CWM where I can wipe data/factory reset and wipe cache partition. After I do that, the phone will boot and will let me interact with it, but after a short time (a few minutes I think), it will reboot again and be in the same state it was before I went into CWM. I tried to do a factory reset in settings. It would say that two reboots would occur, but then nothing happens.
I'm at a bit of a loss as to where to go from here. I don't think that it's an unrecoverable brick, but heck if I know how to fix it.
In between reboots, ADB does see the device in ADB Devices, but shows that it's offline, so I can push an APK to it.
Here are the options that I get in recovery mode:
Reboot System Now
Apply Update From External SD Card
Apply Update From Cache
Apply Update from ADB
Wipe data/factory reset
Wipe cache partition
Any assistance is greatly appreciated!
Ok.. well.. I downloaded and flashed ZVE and it seems to have greatly stabilized the phone. However, it seems that I have lost the ability to do download mode and recovery mode. I can still get into the device through ADB, but ioroot no longer is able to root the device, so I can't install any recovery. There is a system update available to install, but didn't want to do that unless I'm good an stuck in this mode.
I also don't seem to be able to enable the cellular service. I don't know if the update it wants to install would fix that or not.
Edit: I can still do ADB reboot recovery and get into recovery mode with these options:
Apply Update From External SD Card
Apply Update From Cache
Apply Update from ADB
Wipe data/factory reset
Wipe cache partition
Edit2: I was able to root with Stump. FreeGee won't run on ZVE, so not sure what to do from here. The phone does not work at all. None of the phone info is listed in About Phone. No IMEI or anything.
Edit3: I have been able to get TWRP installed and can boot into it. I have also verified that I can get into download mode now. I'm very concerned about my EFS info though. I did back it up, but not to the PC, so effectively I have no EFS backup and no way to recover the IMEI information. Not cool...

Stuck in "Safestrap"?

I followed the instructions here http://forum.xda-developers.com/verizon-galaxy-s5/development/safestrap-odin-safestrap-flashable-t3161043 to install Safestrap on my phone with rooted BOE1, my phone rebooted, and I'm looking at a screen that say Android System Recovery <3e> LRX21T.G900VVRU2BOE1
I was trying to install the MOAR rom, but I fear that now I'm stuck in this strange recovery with no way out. Could someone please tell me exactly what I will need to do to get out, and possibly how to actually boot to Safestrap?
Not to leave anything out, though I'll look the fool if I don't, while in this recovery I wiped Data+Cache and attempted to install the ROM, got some sort of error about footers and signature verification (it happened pretty quick then rebooted) and wound up back in recovery, so I tried flashing the BOE1 kernel, same problem, back to recovery.

S5 doesn't have a custom recovery per se, so any app that "reboots to recovery" will go to the Android stock recovery which your in. You can't flash anything of value in there, and can't install a custom recovery. You should just be able to turn the phone off then on again to get back to the stock rom, right?
It's been so long since I've done it, but won't safestrap only install on kitkat? Doors it even work in lollipop? Must people use flashfire I think
I should probably mention now that I got it fixed. Following more instructions in that thread, I did everything in the order of the first step again, using ODIN, flashed back to NC2 (I think? Going off memory) rooted, installed Safestrap, flashed MOAR, and the OC4 firmware, and here I am.
