Can I just ask about the bootloader?

I'm seeing alot of users reporting there's an issue within the bootloader that is included on the LRX21P image for Grouper, I performed a clean flash yesterday and flashed the leaked image for grouper, I haven't had any single issue flashing all of the images, even bootloader that came from the lollipop image doesn't seem to cause an issue.

Btw, everyone's suggesting to flash the bootloader from JB & KK on this lollipop build, is there any impact on the performance of why's that recommended to flash the old bootloader?

And I didn't really expect this but lollipop made it worst to run on this device! Even if it's a 2012 device, why's that it can't handle lollipop smoothly? I can't even drop the status bar down at a rate of 60fps as promised by Google, can't even swipe the screen smoothly and it's freezing as hell! It feels like something's wrong with this build.

We can't always tell the reason that this is a very old device so that it performs really bad, how come that my 2011 device with a CM11 installed that is still functioning well and smoothly performing operations on just top of its single core 1Ghz and 512 megabytes of RAM? Rather than this quad core tegra device that is WAY MORE faster supposedly?
[Nexus 7 General] Natakranta:
Because Asus used chip silicon chips as requested by Google to bring the cost down. They degrade with time and slow down. My wife's 32GB Grouper is unusable in my standards (using Nexus 5 for list year and OnePlus One now), it lags as hell no matter what, F2FS or ext4, stock or custom ROM, it lags. I so much regret I didn't convince her to change it to N7 2013 last year, as she didn't feel the need to spend money...

I was so looking forward to N9, but not for the price they ask. 16GB is useless, so 32GB is the only option, but 489 EUR (=610 USD) they ask in Europe is way over what I'd spend on YouTube player (that's what she most uses it for) with, wait, wrong screen aspect to watch videos!

The Answer to The Ultimate Question of Life, the Universe, and Everything is: CLEAN FLASH.
[Nexus 7 General] JovieBrett:
Yup, I all agree of what have you said. I tried ext4, f2fs etc etc, none of them improves the N7's performance or at least the stock one has the best performance and stability for me.

Heard alot of users blaiming about the tegra chip for this, they said that tegra chips are getting worst every year and if all of these are true, I have doubts about Nexus 9's performance since even the one of the famous 'Android Police' senior editors have found that there are unusual freezes and glitches from the device itself, idk if that happened on the latest build for N9.

The 2011 device I'm currently comparing to is an Xperia Mini, snapdragon chip with 1Ghz single core, 512MB of RAM, I'll look away from tegra based devices...

Btw, do you have an N7 2013? I'm planning to buy one this December to replace my 2011 device. Can I trust this 2013 model with snapdragon processor? I always trust these snapdragon based devices.
[Nexus 7 General] Mr-Glass:
Not sure what my issue is - after - CF-Auto-Root-grouper-nakasi-nexus7.img it goes through fine (red android) just like it did on the N5 - but the N7 just hangs at the Google screen - I can get back by putting the old kernel back on, but not sure why I am locking after AutoRoot.... any ideas?
[Nexus 7 General] Natakranta:
No, I don't have N7 2013, but I heard that in opposition to original N7, the 2013 model aged well.

If it only had the Snapdragon 800, I'd get it instantly. That would guarantee N5 performance which should be enough for long time

But N7 2013 has Snapdragon S4 PRO, which was outdated already last year.

Still I may consider it if I can get one really chip.

Maybe bad download. Download again and compare checksums.

Or try with SuperSU-working modified stock boot images for lollipop linked in this post

The Answer to The Ultimate Question of Life, the Universe, and Everything is: CLEAN FLASH.
[Nexus 7 General] JovieBrett:
Ok, thanks for the shared-knowledge.

That's ok with me even if it's only 1 year outdated, devices here sells like the price never drops down, it's always too much for the pocket. I'm looking for a phone but N7 2013 LTE is the only one I think I can get by, N5 is too much but I don't want to buy an N4, it's a already a 2 year old device.
[Nexus 7 General] Natakranta:
Save, borrow, sell your kidney, buy Nexus 5 :D

Look for 2nd hand one, it's one year old now, people may start selling their phones soon.

N5 is the ultimate phone. Go for it.

You are considering using N7 2013 LTE as a phone? Does it handle calls?

The Answer to The Ultimate Question of Life, the Universe, and Everything is: CLEAN FLASH.
[Nexus 7 General] JovieBrett:
Lol, I'm living on a 3rd world country. Can't still afford an N5 even if it's a second hand one.

I really love to have one but I have no choice but to get an N7 lte variant, 2nd hand still.

Yup, I'm considering to use it as my main phone lol, struggling hard much :D Yeah I think hahaha
[Nexus 7 General] Mr-Glass:
Thanks for the reply.. Checksums were all good - tried bricked kernel - reinstalled twrp - flashed SuperSu 2.16 - still no joy... kinda at a loss -- considering starting back from previous stock images and working back up to 5.0 -- dunno..
[Nexus 7 General] phileg:
What Recovery to now?
[Nexus 7 General] STB2010:
Worked for me without wiping user data and flashing without wiping.

Seems to be stable so far.

root is working after booting with CF-Auto-Root.:)
[Nexus 7 General] Natakranta:
We have misunderstanding. Bricked karnel on its own won't do. You need either succeed booting CFautoroot.img for it to modify stock karnel or fastboot flash already root enabled stock karnel (boot.img) from the link Show-P1984 drive - there are the files there, one for Grouper, which needs to be fastboot flashed. And then flash superSU.

After that you can flash Bricked for lollipop test version.

The Answer to The Ultimate Question of Life, the Universe, and Everything is: CLEAN FLASH.
[Nexus 7 General] Groid:
I also had the issue of needing to apply the cf-auto-root with the command "fastboot boot CF-Auto-Root-grouper-nakasi-nexus7.img". The way the OP listed it for linux did not work on my Win7 pc. After running the edited command, I have root and supersu after booting back up. So far the system seems a little faster. Thank you so much to the OP. Perhaps you could edit your instructions to add the correct command for flashing auto-root from a Windows machine.
[Nexus 7 General] jetsaredim:
See this post for more information on the issue with the 4.23 bootloader...
[Nexus 7 General] jetsaredim:
The latest CWM recovery should work just fine. I linked to the CyanogenMod wiki install guide that has the link and instructions on how to install the recovery.
[Nexus 7 General] jetsaredim:
Did you flash or boot it? Sounds like you might have flashed it. Under normal circumstances, flash is the right answer for most bootloader installs, but in this case, you just want to boot the auto-root not save it permanently via flash. Might not be your issue, just a thought.
[Nexus 7 General] jetsaredim:
This is just a matter of how you unzipped the CF-auto-root zip file. On my system, it unzipped with 2 directories: image and tools. I added a note for Windows users to verify the path to the img file... Hopefully that clears things up.
[Nexus 7 General] phileg:
Thank you for your answer, but I can not find the link :fingers-crossed: :crying:
[Nexus 7 General] A-star:
Thanks for the guide!

It worked perfectly on my device!
[Nexus 7 General] Mr-Glass:
Thanks for the idea - I still do not know what happened with it - but it was just easier to start over, luckily I did not have a lot invested in that setup.. 2nd time all worked fine as it did on the N5...
[Nexus 7 General] Groid:
Understood. I had copied the .img file right into the platform-tools folder which is where I always put everything before flashing. I didn't realize your command relied on it being in the 'image' folder. So if you just unzip it from the platform-tools directory the command works fine and calls the file from 'image'.
[Nexus 7 General] Colchiro:
Anyone know if root survives a reset?

I'm considering selling my N7 while it's still worth something and need to know if it'll stay rooted.

TIA!
[Nexus 7 General] chowlala:
I ran into the same problem, but happened from a different way.

I had run the entire update as mentioned by OP. Everything checked out fine.

Then my damn fingers decide to become gnomes and try flashing Bricked kernel for the fun of it to test it out.

Bad move Al Pacino.

It got me stuck at the Google logo. Rebooting CF-Auto Root also led to the same problem. Only a stock boot.img modified for supersu worked, but didn't give me supersu.

So what I did was just fastboot reflash boot.img and system.img from the original LP update zips, booted up the system to have it do its usual blablabla, then reboot with CF-Auto Root.

Works like a charm without having to wipe userdata.
[Nexus 7 General] go4fan:
Thanks for the guide. Will any subsequent OTA updates still work? Or what would be the means for updating, where available?
[Nexus 7 General] Rxpert:
No, as OTA updates now check the entire system, not just what's being patched.
[Nexus 7 General] basisforbart:
This worked perfectly for me, great directions. Anyone have any idea if TWRP 2.8 works with 5.0? I don't like not having a custom recovery.
[Nexus 7 General] ZenInsight:
Bumped. I would also like to put a recovery back on. Right now I have CWM, but I don't care as long as there is something.

Great conversations in here. Especially about NAND performance or the Tegra 3 degrading over time. I never considered that a possibility. I hear people saying that with ART and an "ALL F2FS" file system, that would be enough to speed up and save the Nexus 2012. But, I will flash the stock and root it while I wait for the F2FS version. Then I will flash again.

Additionally, I think this is the right thread to get help with this install. So here is my issue. I feel dumb for asking, but I must be doing something stupid. I have plugged in my Nexus, it looks for the driver and of course can not find it. Then I go to the management and "update drive" selecting the Asus one I downloaded. No problem, installs just fine. I put the Nexus into debug mode. New driver installs. again just fine.

I go to CMD (as admin). Type >adb devices. Nothing there.

I tried the adb reboot bootloader (even though there is no device listed...so of course I get

C:\Users\laptop\Desktop\adb_files>adb reboot bootloader

error: device not found

Clearly I am doing something wrong. The device manager says "Adroid composit adb interface" but if I refresh it then it will tell me driver did not install. There is no X mark on it. Arg. Frustrated.

EDIT: Wow. You have to put it into Camera Mode on the USB connected drop down to get it to be visible. Problem solved.

flashaable zip link plz
[Nexus 7 (2013) Q&A] Gforce083:
I've searched and haven't found the answer to this, typically I can figure these things out but I'm at a loss.

About a month ago my 4 year old daughter dropped the tablet (inside poetic smart case) face first on a concrete floor, about a 2.5ft fall. The device was on at the time, but upon picking it up off the floor to survey the damage, cosmetically there was none but the tablet was dead. I could not get it to turn on or boot into the bootloader with several attempts.

A few days later, I took the back cover off and disconnected the battery ribbon for a few minutes. Once put back together, I plugged it into the charger and the LED light flashed as it would when it had a dead battery. After a few hours of charging, still would not boot. I then attempted to try booting to the bootloader and got that to work. However, from there any selection you make, reboot bootloader, recovery mode, start, etc... the device simply turns it self back off. Only once have I got it to go into the first recovery mode screen but then it turned off after making a selection there.

With 5.0 dropping today, I thought I'd give it a shot to see if adb and fastboot commands would recognize it. This is where things get weird for me.

adb devices show nothing listed, if I do fastboot -s XXXXXX devices it will then make some sort of connection. From there if I do fastboot reboot-bootloader it simply turns off again. The bootloader has always been locked and even says so on the device. However, if I do fastboot oem unlock it tells me the bootloader is already unlocked. When I tired fastboot oem lock, it took about 90 seconds and said it couldn't lock it.

I then downloaded 5.0 factory image, attempted to flash the 04.04 bootloader and is says FAILED Remote: bootloader is locked. Attempting to unlock again tells me it's already unlocked. See attached photo of Terminal and device bootloader screen.

Anyone have any ideas here?
[Nexus 7 (2013) Q&A] Gforce083:
So.... just because, I took the whole device apart and then back together again. Held down power button and the thing booted into the OS. However, the touchscreen is not responsive. Looking into that now.
[Nexus 7 (2013) Q&A] Gforce083:
Looks like I got teased.... ever since it fully booted (without touch response) I've yet to manage to even get it to boot into the bootloader.

Not much help going on here, the more I've read the more it looks like a motherboard replacement is what's needed. I'm out of warranty by a couple months, so I guess I'll be looking around the web to see what I can find as a replacement.
[XDA Assist] :
I can get into download mode and if I flash CF-Auto-Root.tar with odin, I can get it to boot regularly and it's running kitkat however the wifi doesn't work. There were a few roms that had to be run from recovery mode to fix this problem, according to my instructions with this rom, however It will not boot into recovery for me to run them off of the sd card. Any help would be appreciated.
[XDA Assist] :
Hi,

Asking in the thread of the rom you flashed is the best way to find help.

Good luck!

Try to do it from the app and it should show connections offer.

I mean from Android app.

Also try going to Main Menu like you see in the Screenshot then you will be in my-verizon logged on mobile browser.

Then you should see Connections Offer on the left side, Under HOME section not plan.

If not then it might be because you have loyalty 10GB Plan before they were public to all people this might be why..

you can also try calling customer service they should be able to do add it for you.
[Verizon Galaxy Note 4 General] lazer9:
Verizon removed offer?

So I just seen this thread today and tried with both stock browser and Chrome via my Note 4 and got this: See attachment.

Apparently Verizon has dropped this already?

[Verizon Galaxy Note 4 General] patt2k:
How much you have total with Promo data? just wondering thanks :)
[Verizon Galaxy Note 4 General] lazer9:
Well, recently I had called Verizon CS regarding that other promo stuff listed here about 10gb data = 30 or whatever and also had noted one user actually opted for a $10 discount off their bill in place of (I believe) taking advantage of that offer.

So in the end. At that point in time, I had 3GB data on my plan. Talked to agent and as I mainly use wi-fi both at home and work and barely exceed 1gb average a month (yet it's nice to know I have some extra in case I want to stream pandora, ect... in car), anyhow, I ended up getting my monthly bill discounted (-$10) and an extra GB of data thrown in to equal 4GB at that time.

So in answering your question, I should be at least temporarily now at 5GB I suppose for the next couple months. :victory:
[Verizon Galaxy Note 4 General] patt2k:
That's not bad.

You can get Loyalty Credit on Contract lines if it has little more then 1 year left on your contract.

Try calling and asking about "Loyalty Credit" not all lines can get it.

If contract has less then 1 YEAR LEFT it would extend contract END date by few months but not the upgrade date.

So you might save even more $$
[Verizon Galaxy Note 4 General] lazer9:
Thanks for the info. Basically I just have my main line (The recently purchased Note 4) a month after my eligibility date from Sept 19th this year and a stupid Home Connect which I don't even use and it's contract expires this Nov 21st... Long story short, ex girlfriend whom I mistakenly at the time purchased and put a phone under contract had broken up with me so instead of paying the ETF, I went on Ebay at the time, purchased a Verizon Home connect box, and ported the number to it.

Looking forward to saving that extra $20 per month very soon! :cool::laugh:

[Verizon Galaxy Note 4 General] RJV3:
Wow excellent find! Just signed up! Thanks for sharing [emoji2]
[Verizon Galaxy Note 4 General] lazer9:
Follow up - So I now open the "My Verizon" app and as also still indicated on the widget I'm still sitting at 4GB and they have not bumped me to 5GB.

There is a little exclamation mark next to the data used circle within the app and when pressed on, simply says:

I have no idea what to conclude from this :confused:
[Verizon Galaxy Note 4 General] patt2k:
in myverizon app or in pc browser it should show in blue Promotional data then below your regular data.
[Verizon Galaxy Note 4 General] lazer9:
Interesting. Well it does show this when logging in via the web to My Verizon. I guess the Rep I mentioned that previously told me he was upping me from 3GB to 4GB prior to this thread/offer, failed to do so.

It lists now 1GB promotional

and

my usual 3GB regular

so total = 4GB

I was supposed to be not only switched to a 4GB plan prior but also start getting -$10 off my bill. Guess I will await the next cycle and see what things show up as. :silly:
[Verizon Galaxy Note 4 General] patt2k:
Can you go to my verizon click on the + button on the top and then go to plans i think you should see all promotions listed under your phone number.

It will tell you when the 1gb ends.

Also looks like the rep lied to you.
[Verizon Galaxy Note 4 General] websterzx10r1:
could it be that your on a month to month plan? I have 2 promotional free gigabytes, 1 when girlfriend edged up on new phone and i added this to my line. Wonder how many times can this be applied to a account i have 4 phones on my account?
[Verizon Galaxy Note 4 General] patt2k:
If you already have 2 promo gigs from Upgrades, this will give you +1 free promo gig for the 2 billing cycles.

I can confirm this on someone elses account they got :

1GB free for 1 year ends in March

1GB from Edge Upgrade

1GB from This Promo til January 6th 2015. (end of their billing cycle)

= 3GB promo on top of 30GB for 130$,total 33GB.
