Corrupted bootloader, memory? - Nexus 7 Q&A, Help & Troubleshooting

I deleted a folder in /data that had some installed software in it. Once I deleted it, the N7 immediately began spitting FCs at me, Aldiko keystore, the WinnIME app, some .pngs, all FCs.
I rebooted and it hangs on the Google screen. I can get into the bootloader by holding volume down, but the menu usually navigated by volume buttons stays on Start and the power/enter button does nothing. No recovery, obviously.
Most depressing, fastboot and adb do NOT work. The closest analogs to this problem I have found through this search is people who accidentally erased their bootloader. It looks like mine may be corrupted, which could end up being no better.
I am out of town and away from my primary Android computer. The one I have with me is Windows, with an Ubuntu VM that has the SDK and confirmed working ADB and fastboot usually. No dice now, like I said.
When I plug in the tablet through USB, the Windows host attempts to install MTP drivers and fails. I would try and install the Windows SDK and try to get a connection through some of the Windows drivers, but the internet where I am cannot take it.
Any ideas? I am thinking the device is toast, but since I would be the first I have heard of to be able to get into the bootloader and still brick, I thought I would open it up to the community.
Details: I HAD CWM, no more. Stock, rooted only.

is there no nv flash for this device.. this is what you need. to boot into nv flash and flash the boot-loader.. .. I think this is the only way. There is another thread that talks about this.. Not sure if they managed it or not but they were very close i think..

Yeah. I used NVflash on the wife's transformer 101. I saw that thread, but i think the resolution was that they finally got close enough to find out they didn't know what they were talking about.
That sounds worse than I intended it. I mean that they simply weren't very experienced NVflash users and so they didn't know what they were missing until they worked at it. Seems a while away, if ever.
I have a second Nexus 7, i am wondering if i can do something with the hardware, maybe. Is all of the storage in one chip? I have the 16 gig, i seem to remember the 8 gig has n actual emmc.
I am going to try and stay away from devices with virtual sdcards from now on. This was just a folder in storage, WTF? I am not even sure how this is possible. Hardlink mayhem, presumably. The device had only ran stock.

yea there is only one storage device inside the nexus.. its all symlinked

If you could get the driver going, send a adb reboot-bootloader command, the bootloader should work then.
Will the next nexus have a longer screen?

Same problem here.

Hi, everyone!
I've got the same problem with my Motorola Razr D3 (XT920). After a system update, something bad happen while the system tried to install the last patch realeased by Motorola. I still can access the bootloader but nothing is working.
So I wonder if any of you guys have figured out how to reinstall the bootloader.

[Q] Got me some boot loops after using a specific font with Type Fresh.

Alright, so last night I was fooling around with "Type Fresh," which you guys have probably heard of. It was released here... It's a font changer...
Anyway, things were going good until I tried a font named, "Joystix," which replaced quite a few of my fonts. That caused my phone to go into a crazy bootloop.
So, at this point, I do not have Clockwork Recovery. I actually have the Stock Recovery. For some strange reason, my stock recovery just takes me to a screen with a red triangle, and factory reset just shows this hard drive and a loading bar that never goes anywhere before rebooting my phone into a boot loop.
I've checked to see if ADB will work in my stock recovery, and it does, except for the fact that my phone is, "offline," which is probably not good.
Is there anyway I can get my phone to work again? I remember when I was getting bootloops and I somehow got the phone to reinstall all the correct stuff after going into the stock Volume Down+Power thing a few days ago. I don't know or remember how. Like, it was going into the whole process of giving me the choices and said, "Do you want to update?" I said yes and voila, everything is back to normal. Sadly, this isn't the case atm. :|

Well I've never personally used type fresh to change fonts, I've done it in other ways. Just a thought for ya, but I would recommend that if you can get adb to recognize your device (cmd: adb devices) try booting into hboot(volume down + power), and see if it recognizes it regularly that way, from there I recommend trying a program called Droid. It's a windows program that I used when I messed up re-rooting my replacement mt4g (tip: Don't try rooting when having been awake for 26 hours for no apparent reason ). It has a feature called Debug Console which fixed a bootloop, and constant force close that I somehow managed. I also suggest pulling your sdcard, getting a usb scard reader, and installing the stock recovery zip (Pdimg or something like that, I forget off hand).
That's all I can think of, hope it helps
...I finally looked at my SDCard via my brother's phone.
Every thing in my SD Card pretty much has "Font" in front of it in regards to the name.
I mean... Yahoo became FontsYahoo.
wat
Solved.
For those who were wondering, I found out that I had to rename the recovery file to the PBNASFASodhwhatever it was.

[Q] Acer A500 bricked. Is it fixable?

So, my neighbor bought an Acer A500 a few months back. He ended up not liking it so I bought it off of him. My tablet and I got really close and I fell in love. I started neglecting my girlfriend and all that. We had a beautiful relationship; my tablet and me. But, a couple days ago I was playing N.O.V.A 3 and it froze. I thought nothing of it and just powered it down. To my dismay, it froze at the Acer screen. I restarted it again and got the same thing. My life was over. My heart felt like it was ripped from my chest... I shed a manly tear.
I've tried vol- and power, vol+ and power, the reset button, D/Ling several different update.zip files and copying them to my SD. I've spent the last couple days reading and trying everything. All I get is the Droid guy with the blue thing swirling in his chest and then him laying on the ground with a red triangle and an exclamation point.
I'm told it's most likely not a hardware issue as things things are almost bullet-proof. But, I am pretty good at breaking things
Am I screwed or does someone have a miracle they can share. My gaming life depends on it.

Do you know what you were running on this thing? Was it stock Honeycomb, scock ICS, or was it running a custom ROM? (If so which one?)
Was it ever hooked up to your PC? (This would help with retrieving CPUID, if it was.) Do you know your CPUID? (Or SBK?)
You should at the least know the answers to these questions before you attempt any type of repair, as it is almost certainly salvageable, but you will almost certainly need your CPUID.

I was running 4.0.1 ICS. I do have my cpuid and SBK. I tried flashing a new rom using blackthund3rs flash tool but it got to about 25% and stopped. I keep losing sync with my PCs, though.

So, do you want to go back to stock, or to a custom ROM? If you wanna go stock, the easiest way would be load a 3.01 EUU, & upgrade on the play market to 4.03. That will prove it isn't a hardware issue. Alternatively, you could root, load a recovery, a bootloader, & flash a new ROM.

To be honest, I really don't care as long as I can getting it working again. But I would rather root it.
I think I can get it to work but neither one of my computers will recognize it. It shows up in APX and says something about recovery driver mode when I plug it into the laptop with Vista automatically downloads a driver and installs it again. I've tried turning off automatic driver install but that doesn't work for some reason. The one with XP Pro just shows up APX device but the APX Flash Tool by blackthund3r says it can't find it. I've downloaded the Acer Iconia 500 drivers and installed them but that doesn't work either. I'm at a loss.
Any tips would be great. I think I have a better chance using my laptop with XP, though. I also need to let you know that I truly do appreciate you trying to help. If you're ever in Columbus Ohio, let me know and I'll buy you a beer. lol

Sorry,I thought I responded to this yesterday, but just now noticed I didn't.
Fire it up in APX mode, and install the 3.01 EUU from the development section, (Stock ROM listing) then simply follow the upgrade path to 4.03, then root. If you drivers are installed correctly, everything will work fine, if not, nothing will happen. If it does start to load the stock ROM, then fails with a write error after it attempts to write the bootsector, you may need to run Badsector, or babsector, depending where you look. Search the recent posts on this, you will find lots of stuff.

How would I go about installing the EUU? I have nvflash and blackthund3r's flashing tools. But I can't seem to get my PC and tablet to connect. When I plug it into my PC without being in APX mode, it just says MTP Device. When I plug it in while in APX mode it does say something about Picasso Recovery Driver.
If you could explain things to me like I'm aN idiot, I'd really appreciate it.
Thanks,
Dennis

Yea, it's still bricked. I did finally get the flash tool to recognize it but it kept hanging up. I also tried Timmy Dean's EUU tool and that hangs up too. I did a little more research and found that I may have a faulty emmc. I ran babsector and got 'fatal error code 9 cannot format partition BCT.' I found a thread here that discusses how to write around the bad sectors using Linux. I'm going to give that a go... I've always wanted to learn Linux. Hey, I can't screw it up anymore than it already is, right? Again, thanks for your time and effort in trying to help.
Cheers,
Dennis
Hey, before you try that, try different USB cables and ports (if u haven't already)
I had a similar problem with my phone not maintaining stable USB link to PC... after 4 days I tried a diff USB cable and boom, snap, working.
Just a thought.....

[Q][Answered] Have I screwed up? (Fastboot not seeing the Tablet)

Okay, I bought a Nexus 10 off someone, and they had already rooted the device. Bootloader is unlocked and whatnot. That's where my problems start. I can not for the life of me get fastboot or adb to see this thing.
Here's my info:
Google Nexus 10 (Samsung)
ClockworkMod Recovery 6.0.4.3
Bootloader Version: MANTALJ12a
Windows 8.1 Pro x64
Full Android SDK
Samsung drivers installed (I rooted my Galaxy Nexus without issue).
USB has a direct connection
Before I decided to format and try to install a stock .zip, I could access the tablet as a media (That's how I got the .zip on the device).
Steps to how I got here:
Flashed Cyanogenmod 10.2 or whatever. Didn't want JB, wanted Lollipop.
Pushed the (what I thought was correct) .zip to /sdcard
Booted into recovery
Formatted /system, /cache, /data, /factory
Reflashed the .zip
Failed. Miserably.
I named the .zip as something simple and just overwrote it. I wouldn't have this issue if it wasn't for that. I know I did a bad there.
But still, nothing I can do will get fastboot/adb to see the device. It makes the sounds that it's connected when I plug it in. I'm using an elevated prompt as well, but it will not pull the device. How do I get myself out of this hole? If I could push a new .zip to somewhere on /sdcard I could at least use the recovery to reflash.
Wrong device ? [emoji14]

No, I was going to put it in the general help thread, may be better here since this may not be a simple question (Please prove me wrong).
Some additional things I've tried:
The NExus Root Toolkit. Removing all drivers etc. Still getting to fastboot by PWR+ VOL+ + VOL-.
Still nothing. Should I go to my wife's computer and try it there? I might do that anyways.

You don't have access to have os then? How did you push your zip if you don't have access to adb?
I have seen people who couldn't get adb and fastboot working on their windows and switching to another computer solved the issues.
Ok, make sure to make a full clean of your drivers. Wug toolkit explain how to. Then install proper samsung driver and this
If it is not a hardware's problem, you should have access to fastboot & adb. You might try on another computer if possible. A clean one would be the best (i.e. never used any droid devices, etc.).
Another workaround would be to use and otg cable and an usb drive with any zip of your liking.
Another one, I had an issue long time ago, similar, I had to flash through odin in downloading mode to fix my problems.
BUT did you really deleted /factory partition? It contains various proprietary files needed for the device to work. Well concerns more devices with imei and stuff to allow 3g connection and co. Might have no incidence tho on your device's behavior.

It's a Wifi tablet, no cellular data and IMEI etc.
edit: As a side note, I've been thinking about reformatting my computer, though it'll be a huge pain to get it back to here as I've got to go from 7 - 8.0 - 8.1 on the upgrade paths to get it back here again.

Did you deleted all samsung vendor, etc from the usb program, you know what i am talking about?
You can force to install drivers from device maanger, don't remember how, when installing manually, you must do some step , install from floppy or file, get inf files or so, you will get a prompt telling you it might be harmfull and it will force installation. Might be the solution?
The culprit is definitely software-sided.
Does the mount internal storage (mtp) work?
Would this be easier in Linux? I could pop open my Ubuntu VM and do this if it'd be easier?
Beyond that, are you telling me to try and install the drivers from the driver files created by the Samsung vendor .exe?
I have tried to 'mount USB storage' from recovery, but it doesn't seem to do anything. /system /cache /data /factory are all mounted ATM and nothing is showing.
You've already got more advanced advice than I can offer but when I tried to update to 5.0.1 from 4.4.4, I couldn't get my windows computer to see my device. I was trying the adb fastboot but it I couldn't get it to work.
Wug's toolkit got it all straightened out (http://forum.xda-developers.com/showthread.php?t=2015467)[*]. There was an option on his interface that asked whether the device was working properly or not (a!most missed it as a choice). Checked that box and it went through much of the process I had done (installing adb, updating drivers etc). Long story short, it worked.
Where did you see this option? The only thing I see is the Soft Brick/Bootloop option where it will install the factory again. Was it that or somewhere else?
I swear to the Android droid that I tried that before. That seems to be doing what needs to be done, holy crap thanks!
e: I would like to know, however, why fastboot/adp wouldn't work but this would without doing any of the other stuff?

You're right. I confused the heading but choosing that option got my computer and my Nexus "talking." After installing the factory image I think you can then push a cusom ROM to you Nexus (http://forums.androidcentral.com/go...acks/264619-wugs-nexus-toolkit-questions.html).

Problem solved ? I always had less issues with fastboot and adb on Linux you can install a ppa that install for you adb and fastboot
Hovewer if you are using 2.8.2.0 you will need 1.0.32 and the ppa includes 1.0.31 so only adb sideload fails.

Wiped Phone, OS is gone and phone is unrecognized

Hello everyone,
I have wiped everything using the TWR recovery boot option in a really poor attempt to unroot my phone since it was behaving strangely.
Now it look like my OS is gone and the phone cannot be recognized anymore by my PCs even if I install the appropriate drivers manually.
Since it is no longer possible for me to attempt to flash the phone with a stock firmware using odin, I have attempted transfering the file on the phone using the sd card and installing it through the TWR recovery menu however it does not seem to be a possible option.
Does anyone have any advice to propose to restore the phone with a working OS?
It should still be able to load a recovery file from TWR, I am just unsure where I could get these since they differ from ROMs available everywhere else, I can also make change directly to the device drive using the file explorer so worst case scenario, I suppose it could be possible to copy past all the content of an image over there via the sd card.
Thanks
what happens when you put it into download mode and connect it to a computer? can you even get to odin mode? there is a way to ADB an OS onto it , but its pretty particular and usually not necessary.

The download mode seems functionnal on the phone, however the phone is not recognized by any PC which render it useless. My guess is that some files or driver on the phone side got deleted and it is no longer sending the right information to the machines it connects to.
Loading ADB into the OS seems like a neat idea, I didnt know it was possible. I am just unsure if flashing from within the phone is functionnal, my guess is that it probably work, but it is perhaps just a little riskier than doing it from an external device.
Thanks, I will try that, if you have any further advice, let me know
Edit : Oh I just realized you said to ADB an OS into it, yeah I don't thinks its possible, since nothing recognize the phone.
Have you uninstalled and reinstalled the drivers on your computer? Tried a few different computers? And, more likely to be successful, a few different cables?

Yes, it also worked perfectly fine a minute before everything get wiped. I am pretty confident the only way to get it back working would be to copy the files into the phone manually, I am just unsure what files I should copy to the root since I have never seen how it usually look.
That's weird because I don't know of a way to wipe stuff in such a way to remove the capability of Odin connecting to a computer

Hmmm I went on cyaogenMod and installed it on my device using the sdcard. Unsure why the stock OS wouldn't work, but at least now the phone is functional.
The phone is still not recognized but it seems like it is slightly better, it now displays as Unknown USB Device (Device Descriptor Request Failed). Which is better than getting disconnected right away from the computer. Now it probably just is a matter of fixing the drivers or the phone further since I have messed around a lot since everything stopped working.
Alright thanks a lot, it didnt occur to me that I probably could install other roms. Im still unsure whether or not I should stick with it but thats the least of my worries right now

have you tried a different version of odin? or at least a new download of it? does your computer recognize it when its booted up?

Most Recent Magisk update won't allow me to boot up phone

My phone is root with magisk and TWRP. Some other downloads from the repositories within Magisk but I don't think that's relevant. Anyways, around 9:10 pm (EDST) on Sunday the 15th I got a notification that the latest version of magisk was available and ready for download. I downloaded and installed. It booted to fastboot with the typical menu to start, restart bootloader, turn off, or boot into recovery. I thought this was weird as it has never happened before and the phone has been loaded with both since at least July. At first I thought it was just a one off and started the phone. It came back to Fastboot mode and will not let me do anything besides restart and once it does that it's back in fastboot mode. ADB is not recognizing and like I said I cant get any farther than the phone booting into fastboot mode. I'm a full time student with no money for another phone and I was dumb enough to do all this on my daily driver. I am not well versed in phone modding, just enough to be dangerous. Is there any recourse or action I can take to get it back to working order or am I just screwed? Any suggestions welcome as long as they are productive. Thanks
I have the same exact problem going on with my phone. I'm in the process of trying to unbrick it as we speak. If I see any success, I'll be sure to share what I did to remedy the issue.
PS - my problem might be slightly different, as initially I could get to TWRP recovery but I made the mistake of wiping the entire device, which seemingly included all partitions, OS and all. So now I don't even have TWRP and can only get to the fastboot screen. When I try to boot the TWRP.img I get an error... I'm rather new to dealing with a bricked device so this is definitely a learning process
You will lose your data, but this guide should get you both up and running.

Yeah, you guys shouldnt be too scared about your phone being bricked but data loss could be an issue. MSMDownloadTool will almost always save your phone and if you are able to boot into fastboot you could just flash a factory image straight from the OnePlus website. If you want to recover files on the phone maybe try booting a twrp image in adb and if the encryption key is still intact you may be able to USB file transfer the data off of the phone.
Does the msm download tool work on Linux or does it require Windows? I downloaded it on a Windows laptop but it was one of the newer laptops that had zero internal storage and instead uses OneDrive in lieu of, so I downloaded the tool to a thumb drive but Windows wouldn't open the .rar file. Any help or insight is greatly appreciated. Thanks!
Is it allowing you to boot to recovery from fastboot?
If not you will have to use MSMDownloadTool and lose all data unfortunately
I would recommend using Syncthing for the future. It atomatically backs up your data to a local PC.

Try flashing the Magisk uninstaller ZIP, boot the device and hope it boots, then reinstall Magisk using the ZIP in TWRP.
I'm not at all worried about losing my data. I do have a relatively recent backup on my computer but I really don't care whether or not I need to start from scratch, however I'm still wondering if I'm able to use the MSMdownloadtool on a Linux machine or not. I was led to believe that it needed to be run on a Windows machine but for some reason I wasn't able to run the program on an HP laptop running Windows 10. Not sure whether it's relevant or not but as I mentioned above in a previous post, the device has no internal storage so I saved the program to a thumb drive and when trying to open it windows asked me what program it wanted me to open it with and/or whether I wanted to search the software / application store for a program with which to run it, leaving me to believe that it may not be something that I can run on a Windows operating system after all. Or, is it just the fact that I save it to a thumb drive? I can try to get another windows PC that may have the space internally or if it will run on my Linux PC that would be ideal. I'm just sick of using this old Motorola Droid Turbo POS LOL.
OP - how are you fairing with your issue?
Thanks in advance everybody for your help, I promise to pay it forward if and when anybody else is stuck in a similar pickle where I might be able to offer any advice to remedy their situation.
PS I Love syncthing but ironically stopped using it regularly some time prior to the **** hitting the fan
Problem fixed, thanks for those of you who chimed in!

Used fastboot flash all partitions and got it going again currently on android 10 running Syberia Rom. Turns out that it was flashable even though I wasn't getting any response from the computer as far as identifying the phone. Freaked out after a few days with no responses and purchased the 7 pro ^_^. At present I'm messing with that. Looking at RomAur-V2.0 to upgrade this the 7P to 10 since, for some reason, my international hasn't received the OTA.

Just use Oxygen Updater app on the Play Store to update your OnePlus 7 Pro to Android 10.

Yup, that's why I always keep a magisk uninstaller zip on my sdcard!
