Bootloader issues

[MENTION=3110798]WugFresh[/MENTION],

with all due respect..i think you're the only one who can help me now..;'( Sorry for sort of hijacking your thread for this issue mate.

My nexus 7 grouper had been running on multirom TWRP for sometime now and running Optipop custom rom by [MENTION=5373714]freak_97[/MENTION] and Slimkat by the same guy for my secondary rom.. All was running well until a few days ago when my tab was acting strange...i was encountering some freezes and all i could do is to force reboot by holding the power button...and i also noticed that if i leave my tab idle for long it shuts itself unceremoniously and it takes a long time before i can turn it on again...it still boots into the OS..until last nigh when it finally happened..i was using chrome..which we know is a ram eater..my tab froze and again i was forced to do forced rebooot again..then i found it not able to get passed the google screen..just stuck there forever..so again i have to long press the power..yes i can still get into bootloader mode..when i tried going into recovery it only shows the TWRP intro screen and freezes there..so now i'm screwed. the only way i can get out of there was by doing the force rebot again and going into fastboot and power off from there (i found it weird because i have to press all 3 buttons together to successfully enter fastboot.

this morning i tried to flash factory image using your awesome NRT (latest build)..all goes well until the bootloader flash section where it fails with an unknown error message..i have tried many factory images for grouper..even the oldest (4.1.2) but to no avail..i researched about APX mode..i researched about NVflash because i'm suspecting my device is bricked...the weird thing, to add to the list, is that when i boot/turn on the device..on the google screen the menus are above..those selections like (Start, restart bootloader, recovery, power off) so that's weird right there and i know that my bootloader is screwed. i tried flashing the 4.23 bootloader (i found from here, xda, after hours of research that most bootloaders on google's factory images are screwed..so now i'm stuck with an Asus Nexus paperweight.;'(

Quick beginner question here:

I know this is the Nexus 7 forum, but since it should work exactly the same with my Nexus 4, I'm asking in this thread. I'm trying to backup my Nexus 4 and then install Cyanogenmod. I am a complete beginner to all this, and I have never had anything other than Stock Android on my phone - it is 100% stock and has never been rooted or anything. So I really have no clue about it.

I have googled a bit, and it's confusing, because most articles about this phone are 2-3 years old and I'm not sure how it is nowadays. I've seen somewhere, that I need to create a backup of my stock phone (Android 5.1.1), before I attempt to do anything. However, if I click "Create Nandroid Backup w/ Custom Recovery" on Nexus Root Toolkit, it says my device needs to be "unlocked", but if I want to unlock it using this Toolkit, it says, unlocking will wipe my data. So I'm completely confused about what to do now.

Is there maybe a current guide (at least for Lollipop) for Nexus devices, that explains EVERYTHING from backup to flashing the ROM, step by step, for someone who's never done this before? Or could someone help me out here? Thanks a lot!
[Nexus 7 Android Development] jman316:
Right, so thats me sick of the terribly unuasble device that is Nexus 7. It is terribly slow (5.1.1) and unusable and i think its time to do the shebang on it. I have purposely not tinkered with it until now but i dont think i can use it like this anymore.

Ive just downloaded the toolkit and now im waiting for the tablet to charge up before i start. Will report back. :) Thanks in advance....

Please update TWRP recovery for Nexus to the latest version available (2.8.7.0/2.8.7.1).
[Nexus 7 Android Development] milski65:
Not sure why it's not available for you but I got the update to 2.8.7.0 and downloaded it a couple days ago. Installed on my 7 now.
[Nexus 7 Android Development] lennydude:
The original TWRP 2.8.7 + was bad...........................it works now.

You can use an app named "Flashify" to download it.

I didn't find any notification in this thread about TWRP 2.8.7.0. For that I posted it.

The current TWRP for Asus is 2.8.7.1.

$Thanks

@wugfresh: Confirmation number: 3FB267632M846142K. More when I get CWM Recovery working from a cold PWR Vol- boot ;)
[Nexus 7 Android Development] thestrangebrew:
Thanks a ton for making this! Helped me so much. Good job and looking forward to more dev. from you!
[Nexus 7 Android Development] WugFresh:
Thank you! The cold boot CWM recovery issue on the Nexus7 is unrelated to the toolkit... but I guess I do have some ideas on how it could be resolved. I have a feeling that its bootloader related, and maybe the utilization of a modified bootloader would fix the problem. I am not sure what modifications would need to be made, but maybe another developer with more experience with that could figure it out. I will ask around.

Thanks man! I am happy to hear it helped you out. I look forward to that too ;)

[Nexus 7 Android Development] WugFresh:
Regardless of what method you use, this toolkit, or a manual approach; no matter what, you will have to (1) configure your drivers and (2) download a full factory image package for your device. So regarding your internet connection.. I really can't help you out there. You may wan't to go somewhere with public WiFi to download the files you will need. This toolkit alone is 130MB and the factory image packages are around 100-200MB....

If your drivers were properly configured.. then you wouldn't have to "install them every time". I don't even fully understand what you mean by that...? I strongly recommend that you uninstall all previous drivers using USBDeview (which is included in this toolkit, or if you plan on doing everything manually without this toolkit, you can grab USBDeview from Nirsoft). I personally do not recommend the Naked drivers. I keep hearing inconsistent feedback. Maybe they are good for other devices, and I respect the developers work on them, but for the sake of getting you up and running, I recommend using the raw drivers included in my toolkit and configuring them manually, or using the PDAnet drivers.

Here is a great video guide which goes over all the driver configuration with PDAnet, and using my current (needs to be revised) driver guide: http://www.droiddog.com/android-blog/2012/07/google-nexus-7-root-how-to-video/

Hope that helps.

If I install CWM using this Toolkit, can I also REMOVE it using this?

I see the option to install CWM, but not to remove it...other than removing Root of course...
[Nexus 7 Android Development] caanda45:
Of course flash stock and un-root will bring you back to stock with a stock recovery.
[Nexus 7 Android Development] WugFresh:
+1, also there is a button in advanced utilities which is called 'Restore Stock Recovery', just for removing custom recoveries.

{{ WugFresh }}
[Nexus 7 Android Development] ldzman218:
Thanks for the giant response. By uninstalling and reinstalling every time, I mean that I have to use usbdeview to remove all my drivers, and use PDA net to install them again. The problem comes when setting up PDA net, because it requires a device in USB debugging mode. Sorry if I wasn't clear, but what I really need is some way to a) install some bloody drivers so I can use the toolkit, or b) find a method of unbricking my n7. Thanks a lot for the response again, and sorry I wasn't clear. Several hours of desperately scrambling over my brand new bricked n7 has a way if taxing the mind
[Nexus 7 Android Development] WugFresh:
Oh. You can skip the part where you need to plug it in with usb debugging. PDAnet will say it's uninstalling, and you will get some error messages.. But at that point in the installation the drivers have already been installed.

A million thanks, for making this tool.

Unlocked, rooted.

Having fun.

Could I then reverse the instructions to remove SuperSU and keep Superuser?
[Nexus 7 Android Development] R3dbeaver:
just wanna say thanks, bro. and yes, i clicked the thanks button ;)

GJ!

ps: my device is JR003D. install option is JR003C. root works just fine though and thats all i need.
[Nexus 7 Android Development] torpe:
@stewarta: Already tried this. Doesn't work (doesn't change to #). BTW I have a Nexus S, not sure what happened. Is there any chance that switching to Chainfire's Superuser app could enable OTA Rootkeeper to restore root? Which one does this tool use?

@Wugfresh: Since I most certainly have to unlock and than root again, will your tool take care of all the legacy (busybox, su app, ...)?

Thanks!
[Nexus 7 Android Development] ldzman218:
Oh wow. Thanks for the advice, I'll try that and post how it works

Edit-fixed

[Nexus 7 Android Development] WugFresh:
Superuser no longer works. I have no idea why development halted on that, but that's the deal. SuperSU is just gonna to have to be our new friend.

{{ WugFresh }}
[Nexus 7 Android Development] stewarta:
Yes, I agree that it is the bootloader and not your toolkit. It certainly isn't CWM Recovery either as I am now using v6.1.0. I too am digging around ....Thanks for all your efforts though.

---------- Post added at 10:03 PM ---------- Previous post was at 09:57 PM ----------

I don't think so. Sadly, you may have to start again with Wugfresh's root kit. I think that way you can unlock, root and reinstall your apps ... then immediately do a Nandroid backup by using ROM Manager to either boot into recovery mode, or simply use the BACKUP menu item in ROM Manager. That way, you won't have to go through this again (hopefully). It is safe to update to CWM Recovery 6.1.0 or Touch.
[Nexus 7 Android Development] Shawn_230:
Not laying any blame here, but any chance downloading the Toolkit just gave me a virus?

I clicked the link in the first post, downloaded the installer from Softpedia (US) which installed the Toolkit just fine, but then I chose to setup the device drivers which wasn't successful. So I rebooted and next thing I knew I had Security Shield 2012 infecting my computer and not letting me do anything like pull up task manager or anything.

Just wondering if anyone else got this? I haven't downloaded anything else lately...
[Nexus 7 Android Development] thistimearound:
Thanks for the quick replies. I don't want to be friends with SuperSU, he's the new kid. I suppose I'll give it a try. Thanks again for the toolkit working great.
[Nexus 7 Android Development] caanda45:

Apologies for the dumb question.

I downloaded WUGs groovy toolkit & rooted my Nexus 7. Yay!

Can I use the toolkit to put a ROM on my Nexus 7 as well? I want to take my device back to Jellybean 4.1.2 (with all the extra google crap stripped out except google play store).

Before to ask an answer please think if your answer is enough clear to provide an answer.

Your request is too generic to provide an answer.

You want to upload ROM. Stock or mod? In which way?

Are you sure to read carefully first post? then next write down to jisut did it before to claims if someone suggest to do it.

In the first post is already explained all things that NRT can do.

[Nexus 7 Android Development] manymarius73:
Resolved.

Hi. I know this is gonna be a basic question for ya'll, but I can't figure it out. I'm have a nexus 7 2012, with build number LMY47V. I can't get past the driver installation. I keep getting this error: windows found driver software but encountered an error while attempting to install it: Android Composite ADB Interface. I've been through the steps, but I can't find the problem. Any help is appreciate it.
[Nexus 7 Android Development] NLBeev:
While connected (N7 - PC) use device manager to update the driver and choose a driver manually (look for driver on PC).

Another option.

Disable existing drivers with remove option.

Look in the directories of NRT for drivers and try.

bootloop vs modified bootimg

So.. I wound up with the black screen of death on my Nexus 5 running 5.1.1. The only thing I can do is factory wipe (or flash stock) which get's me back up and running however losing all my apps and data. But if I restore nandroid (twrp) OR restore data partition.... Immediate BSOD!

I was able to find a 5.0.1 nandroid (cwm) that semi works (its a few months old) to rebuild me (I had a couple of apps that I could only use if recovered from backup). I used NRT, like I normally do, and upon reboot after flash I am in a boot animation (4 colored dots) loop. I've restored multiple times, let the loop run as much as 24 hours with no progress. The only thing I have been able to do to get into the phone was to "fastboot boot modified boot.img" from advanced utilities. This works as long as I don't have to reboot my phone.

My question(s) is would it be NOT adviseable to permenantly flash the modified bootimg to my phone to survive a reboot? What's the difference between stock and modified? Any idea why my nandroid fails without using the modified boot.img?
[Nexus 7 Android Development] barclac:
Hi ,I'll try again my last post was not answered, I'm trying to unroot my phone flash stock to start over again, I'm on n5 ,my pc is running w10 preview, everything seems to be OK, nrt recognized my phone and the drivers are OK,my pc recognized my phone, firmware is downloaded OK,but when nrt say's rebooting phone, nrt say's waiting for phone, and twrp which is 2871, stay's on start,and that's where it stay's, I've left it like that for about 40 mins but nothing, so had to reboot back to the original rom,which is catactysm, please help.

I'm likely reaching here, but you may want to try using a slightly earlier version of TWRP or even try with another recovery like CWM.

Thanks mate, but tried that as well, didn't make any difference.
[Nexus 7 Android Development] finneginsfast:
I've noticed some strange behavior in my pc since installing the drivers for this that may or may not be related here. Seems as though when my N7 and or phone are plugged in that they will get the autoplay popup which in itself is normal. Once I dismiss it however it seems to continually and randomly popup and it's getting annoying.

Could this be related to the drivers that have been installed via this install process with this tool?

[Nexus 7 Android Development] chrisnewton:
Hi all I have just flashed my first rom using this toolkit and it went OK, however I want to flash another rom but I'm stuck. Because I have flashed a custom rom now when I click on flash zips and file is already on this computer it won't open the box like before because the build has changed, how do I go about flashing another rom? And how do I wipe everything first as I assume you can't just flash a rom on top of a rom?

I´m having trouble using the toolkit with Windows 10, especially the fastboot commands do not work.

Has anyone encountered similar problems and has maybe solved them already?
[Nexus 7 Android Development] shobuddy:
I'm on Windows 10 as well and had no issues last week. What specific error(s) are you getting? I did a clean install of Win 10 so had to reinstall drivers. Not sure how it works if the drivers carry over correctly if you're doing the 10 upgrade.
[Nexus 7 Android Development] The Apostle:
I am baffled. I have been flashing phones and tablets for years. Recovered from soft bricks, etc, etc...

Last night I decided to root a new Nexus 7 2013. The device came with 5.1.1 (LMY48G). I read several posts and watched some videos. Then I d loaded the WUGfresh toolkit. First I did all the driver stuff, then unlocked the device. Everything was going fine. I confirmed the device was unlocked by visually seeing the padlock on the splash screen while booting.

Next I tried to root. I chose the root+install custom recover option. When I did this the device would boot into TWRP but never get any further. I manually told TWRP to reboot the device and it said no OS installed. I rebooted anyway to see a bumch of RED script. The device rebooted and works fine but I cannot seem to root it. I am baffled. I restored to stock but have the same issue. TWRP keeps telling me no OS and I cannot get this thing to root.

Any suggestions?

[Nexus 7 Android Development] Cheech1976:
I upgraded to Windows 10, no clean install, but I deleted and reinstalled all the drivers from the toolkit, to no avail.

The command flashtool doesn´t seem to be working.

When erasing or sending to the various partitions (boot, recovery, system etc.) i get an error message like "invalid arguments" or "too many links".

I will try to un- and reinstall all the drivers again.
