My apologies, as I wasn't sure where to post this.
For a long time now I've been running CM7 both the nightlies and the weeklys with no issues. Yesterday I decided I would try Neutrino ROM and installed GT 2.5. After that I noticed I had no data connection so I attempted to patch the ROM using Notorious's recommendations to no avail so I installed 2.2 and the Google addons, Sync, etc..
All was working great, however everyone said 2.5 was better in the forums so I installed it again today and attempted to patch as explained and this time was successful. I had data connection again and all was well. About an hour later I went to use my phone and it was completely black.
I attempted to power it up and nothing happened. I finally had to pull the battery and was able to get it to boot up properly, however my data connection was gone again. I ran the sysctl -p command in terminal again and rebooted it to no avail. I finally decided to go back to 2.2 which worked properly last night, however after installing from the zip and the addon zips it went to the 'Dual Core' screen and then rebooted back to the 'Dual Core' screen and keeps doing that.
I attempted to go into Recovery Mode, however when it says 'Entering Recovery Mode' it just goes black and I can't power it back on. I then have to reseat the battery before I can get it to work.
I guess at this point, is there anything I can do to get my phone back? I've seen the hard brick messages and I don't have that (yet), but I am not sure, because I apparently can't get that far. Thanks for any help you can provide.

Sounds like a hardware problem to me. I recommend taking it to a service center ( for me ATT has one I use.) and sometimes they can boot it up. Or they can maybe give you ideas.
Just to confirm you can't boot anything right??

Thanks for the response. I was unable to boot into Android Recovery, however I hadn't tried the others. After numerous searches I found information on how to use moto-fastboot to install RomRacer's Recovery image and after doing that I was able to get into Recovery (phew!). I did a complete wipe on the phone (Dalvik, system, etc) and installed Neutrino 2.2 with Lite gapps, United States (GPS), Sync, and Gtalk (for video) and shockingly it finally booted into the rom. I think at this point I'll leave it alone after restoring my apps via Titanium Backup.
My phone is now working again. Hopefully I can keep it that way.

Firstly I am new to this and want to apologize for my english since it is not my first language, so please go easy on me
I recently did my first ever rooting on my new N10 16GB using CF-Auto-Root and did not flash custom recovery. It all went fine and worked great until last night when I tried changing fonts using Font Installer. After installing a font and rebooting, the device wouldn't boot past the X-Logo.
Restarting didn't work and after reading other threads I entered Recovery and did the Data Wipe/Factory Reset, but still get stuck at the X.
I tried the Clear Cache option and have done Data Wipe/Factory Reset several times, with and without USB plugged into computer, without any results.
Also, I don't think I enabled USB Debugging after rooting, if this makes any difference right now.
I really don't know where to go from here and as this is as far as my experience goes in these things and not wanting to mess up the device completely, I now turn to you for advice, hoping my dear tablet is not beyond rescue already.
Please please help me out!
SOLVED! I used this guide doing a stock recovery and it's working again!
Keeping this post if it may help someone else =)

Hi All,
I've searched across forum to find also similar cases, but no results so far.
I have a N4 with TWRP and CM (previously running 10.1.2)
Today I decided to install the new 10.2.
Installation went fine but after the restart I've noticed some strange behaviour with some applications (missing from phone, but installed for my play store account)
I've decided to reboot again the phone, and since that time I'm stuck with the black start up Google screen (the one with the lock at the bottom).
Entered recovery mode, I've wiped Dalvik, Cache and System, but no results, rebooting is always stuck on Google screen (I've also left it there for 15+ minutes, no changes)
I've tried to install a previous ROM (zip available on phone storage) but no result even in this case.
Any help or suggestion would be much appreciated, even a link pointing to similar case happened in the past.
Let me know if any further detail may be needed to better understand the situation
Thanks!
mh a wipe/factory reset should be working...
Try pushing a different rom with ADB to your device, then flash it.

This is usually happening when you don't flash something right. I'd go back, flash it all again with wiping everything and flashing it by the right order and stuff. If it doesn't work, as written above, flash other ROM through ADB or something similar.
Besides, you could always restore your nandroid backup, and if you don't have one, learn from your mistake
Good luck

To be honest, I've already tried to revert back to previous CM and even to the factory image from Google, but it always hang on the google screen.
I've not yet Format/completely wiped the phone, and that's my last option.
Once I'm done with the manual backup I'm doing via adb shell, I will try again to flash a new ROM, and see what happen.
Definitely I'm learning from my mistakes
I flashed the android 5.0 image from google website using NRT and then rooted the device. I have TWRP 2.8.1.0.
The problem is that my nexus 7 2012 12GB is giving me unbelievable lag. I have cleared cache and all but it is of no help.
I have no idea about F2FS but I read that changing to F2FS might help. So can any of you tell me what to do.

I had that problem when I first flashed the factory 5.0 Image, without wiping data. It was horrid. The situation didn't improve after wiping data.
Later I flashed the ROM in my sig, and it is working very good. Occasional lag, but nothing worse than kit-kat. Overall the performance is much better than kit-kat.
I made sure to wipe, format, and repair data, cache, and system. In fact, that ROM wouldn't even boot until I did.
I wiped, formatted, and repaired, then loaded the ROM and GAPPS manually via ADB and flashed both normally using the TWRP interface.
Bootloader: 4.23
TWRP: 2810

Factory reset does wonders. Lollipop works great after
I was having the same issue, then uninstalled Facebook and it has been fine since.
I had lag issue with google launcher. I am using launch came with Rom and nexus is much better. I am using f2fs Rom w/o google launcher. It's very usable.
I turned on Develop Options then scrolled to the bottom and checked off "Kill all activities when you leave them" and I really don't have the lag anymore.

Thank you for this tip. I did this and now its like having a whole different tablet. It is usable again. The only thing is in my developer options it is called "Don't Keep Activities."

Also, scale all the animation speeds down to 0.5x in Developer Options and you'll love the snappiness It works great on my Nexus 7.
wiped cache, 'Don't Keep Activities' and whatever i could find still laggy as sh*t. Will wait for 5.0.1 OTA if that doesn't work back to 4.4.4. Any other suggestions without resetting/wiping ?
Try to run fstrim on /cache and /data
try this fix
I was able to fix my nexus 7 2012 lagging problem after the lollipop update and now it is as fast as before. I posted a video on how I did it and there is no downgrade or rooting required. Here is the link youtube.com/watch?v=OH2iYdr91DE

u captured and uploaded a whole video just to tell us that the lag was fixed after turning location service off?!
I just received my nexus 7 2012, bought it from someone and it had 5.0.2 already installed on it.
This thing is sooo slow that i was wondering if i made a bad buy by getting this model.
Everything is super laggy, for example,.. 9gag or facebook, when it finally loads i cant scroll through it, its so slow it crashes the application before scrolling down.
I tried the wipe cache, enabled "dont keep activities" and set all animations to .5 in dev mode. i tried disabling location.
It all made it a bit more usable,.. but i read people having a smooth and fast device... which i dont have still.
what else could i try? as far as i know its not rooted and has the stock rom.
I really want to like this device but its not happening so far.
Any help is really appreciated
Most of the custom roms fix this issue. very fast now!
I am waiting for 5.0.3 and hoping it helps!

I am not going to hold my breath. After I did a full wipe & installed 5.02 that did seem to help.
I had really bad lag after flashing 5.0.2. I discovered (while trying to install Busybox) that the system partition was full. I deleted a few system apps (stuff I could get from Google Play if I ever needed it down the road), freed up a few megs, and things got instantly better.
Lost 1/2 my storage space
After factory resetting & flashing LRX22G on my 16Gb nakasi/grouper Nexus 7, it has turned into an 8Gb device... I've just spent the past 7 hours setting it all up again, so I am less than keen on factory resetting it all yet again to try & get it working as well as it did under Kitkat before I was stupid enough to upgrade to Lollipop. On the plus side, the horrible lag has finally gone (I think that it is the factory resets & cache wipes that fixes it, but I could be wrong). Now all I need to do is to find out how to convince it that it is a 16Gb version without having to factory reset it. Does anyone have any good advice on that please?

No, I take it all back! The horrible lag & frequent crashes are still here on 5.0.2 & exactly the same as they were on 5.0, & after an afternoon trying to use my tablet I am having no luck. Now my problem is that because I have lost half of my storage space, I don't have enough space to copy back my nandroid backup of my lovely, fast, & fully functional Kitkat installation.
Good day everyone, i am going to report my delicate and infuriating problem that has been haunting my head for two months
I'll describe my problem in extreme detail, hoping you guys able to identify this disaster.
My android phone is Lenovo A6000 Plus, i've bought it 2 years ago and it's running on latest Lollipop version 5.1.1 I never alter the system files, since i only use my phone for games and communications, and i'm not really into tinkering android's software. so i use my phone like a normal person, do the updates when the settings asked me, update the apps, etc. and this phone running smoothly in my service. i wanted to ask both WISDOM and HELP in this thread.
1. The Bootloop disaster symptoms started on april 2018, when the phone boot SLOWLY AS HELL, seriously.. it took about 1-2 hours to boot, and it also shows the (ANDROID IS UPGRADING 0/132 apps) like wtf? , i haven't update or install any new android apps before this symptom happened. So i leave my phone plugged in and wait it to complete the upgrade; then it worked normally as it should. Unfortunately, it happened EVERYTIME i turn my phone on, EVERY SINGLE TIME.. T_T. so i struggled to avoid my phone from running out from battery as i can. This symptom happened for 3 weeks and it got from bad to worse. I wonder what kind of problem is this?
2. The worse part came when my phone is running at high RAM usage, let's say, i game on my phone alot in my spare time, using the ram up to 1800mb everytime i play game or open chrome browser (Lenovo A6000 plus have 2GB ram). When i close/task manager the apps, my phone launcher wont appear normally as it should (long pressing bottom left button) and it FORCED me to restart the phone and suffer the 1-2 hour LONG BOOT. That's unusual, i cleaned my phone regularly (using cleanmaster) and preserve both of my internal and external storage with 3-4GB free space. I wonder what kind of curse is this?
3. So the bootloop disaster finally got me this May when i turn my phone off and tried to reboot. And... no Android is upgrading 0/132 showed up, i waited for 4 hours and reboot my phone again and again and again. And its finally STRANDED on BOOTLOOP :crying:
Im on panic mode when problem 3 happened, then i searched the almighty Google for help, and found that i can backup my data with TWRP recovery, so i do as it said, followed the guides and BACKED UP all of my data.
For once i felt relieved my data is now saved. Now onto the main problem.
I've had enough of this problem so i format the phone into factory reset, wipe the Dalvik ****s, cache, system and data. All of it. thus, making my phone virgin again.
4. Now im trying to resurrect my phone, and tried my effort by downloading Stock Lollipop 5.1.1 OS again along with its prerequisites. I tried to zip-install it using TWRP but it said that "has not switched carriers and cannot be upgraded" i scratched my head and searched almighty Google again then found that i need to do ####6430### thingy before doing that. umm.. so my phone domain need to be changed, how can i do that with a phone who can't boot? (I'm from Singapore btw). What did i do wrong?? did my phone just turned into useless BRICK? but i've read that bricked phone can't even start the recovery, yet my phone still able to start either with Lollipop stock recovery or TWRP (if i adb fastboot it with adb tools from .cmd), so it's not totally fuc.. uh., BRICKED and i got the chance to fix it.
TL;DR
So, Guys.. i desperately need help. i'm a peon both in work and college, and a dead phone will not make a great company for a person like me.
I searched for enlightments and breakthroughs but always ended up failed resurrecting my phone, can you guys PLEASE :crying: tell/give me a SAFE and WORKING walkthrough to re-install my Lenovo A6000 Plus with Lollipop 5.1.1? And does it running a custom OS like those Cynadrogen thingy is good and worthy enough to speed up my phone? is the chances of getting bricked is unavoidable when running custom OS? I thought its going to be easy like reinstalling Windows, but i was wrong.
FYI, my phone now is UNROOTED and running on TWRP 3.0.2 and i can easily revert it back to Lollipop stock recovery if needed (does it considered rooting if i install custom recovery?) I also need a valid info if my phone would never turn like this again if i resurrect it again.
PLEASE HELP ME PEOPLE
THANK YOU.. ! :highfive:

When 5.1.1 update arrived?
Okay lets get to the point. Just don't panic. You have the stock rom file, extract a file named 'system.zip'. Now go to TWRP, perform advance wipe (wipe dalvik, data, system and cache partitions) and flash that file from TWRP. You'll be on stock rom with a fresh new experience.

Custom ROMs are amazing and far better than the stock lenovo rom. Believe me, no one here is using that crap stock rom. You just need some instructions to flash and your phone will get a new life. We are here to assist you.
