Corrupted bootloader, memory?

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.

hard, or possibly soft bricked sm-t230 tab 4 7.0. please help!

Hi y'all, i recently within the last month 2 months taken up a very unsual craving for delving deeper into my technology, with that being said. my tab 4 7.0 sm-t230 i Downloaded an app called "lucky patcher" was messing with it, been reading about deoxe(ing) my tablet,it gave me the option to do it for me (usually i enjoy the challange of using a emulated terminal and what not) but every file etc would take too long, and it worked, my daughter ot well over 150 million score on subway surfers etc. i notice my phone sluggish even bein over clocked, I/Os that i did myself, running max cpu and performance i could blabber forever since my 3 kids arnt interested in my newly found hobbie and my husbands a truck driver, i'm getting it out here (i'm sorry but i do need help) so anywyas i decided to kick her into recovery and begin to just manually delete all the dex copied files through TWRP went good till i wetn to reboot after staring at my screen for 3 hours and got threw up on twice from sick babies and i was boot looped. i decide to restore a previous freshly flashed rom/root backup. well they were deleted too. and all i could do was a master re format i think is what i read it was called, and excited to get back and re download everything i notice i now have no OS and no recoveries and TWRP fulll of emptiness. i can play through TWRP i've changed file permissions i've tried everything ive read and tried everything i learned and experianced to fix this issue, and yet stillno idea how to fix this issue..
Now the fun part is my set up. the only pc i have means and access too is my samsung Chromebook, and my tablet, that's it, no phone because my tablet handles everything my little heart can desire.
needless to say, i need some kinda recovery tool kit i can use via my chromebook, that'll allow me to use ADB for chrome (which another question i have is how do i enable my tablets USB debugging if i can't get into the phone?) so toolkit for chromebook for a ADB side load if possible. or some way to do it through my emulated terminal in TWRP,. my minds rushing, i'm confused and my over emotionally stressed female head is killing me without my tablet. (drive to any town where i could use anything but my chrome book. 3.5 hours.
sorry i pray this post doesnt get deleted. I need help because my tablet is my main source of income being in real estate when i'm back in town once a month. never made a page or a forum or anything like this usally google magic does it. but 3 days and countless mind numbing forums i've given in.. please help me! i'll donate pay something idc at this point. -a pissed off irish southen woman on the verge of pms and a meltdown thanks in advance i'll try to reply as fast as humanly possible, ill be up for awhile tonight going through more posts.

0well with a little more tinking around, i think i have found the issue as too why no matter what i do i'm unable to boot a rom/os. mt EXT3 wil not mount my system i'm clueless as to how to fix that at all threw TWRP, anyone have an idea of any kind please? i'm for anything, even if after more attempts and countless hours, i'll record me skipping it across my lake, and we'll all take guesses as too how many skips it'll do. hopefully my dog will fetch it if i throw at the wrong angle. (completely dumb jokes are the only thing keeping me from returning Sain.) we all cant be too serious. please very interested on how to fix this issue tho.

s,
you need to get a custom rom zip onto an sdcard, check development section.
in twrp, flash the rom,
if the rom still doesn't boot, then reboot to twrp again and use the format data option, then reflash rom and try again.
twrp terminal sucks, you can try flashing aromafm https://www.androidfilehost.com/?fid=95916177934547314
this is for the marvell variant, it may work for the msm/qcom variant.
stop using lucky patcher.

Hi, that's where another problem lies within, I have no way of communicating with the phone or being able to do much, considering the only pc/laptop i have access too is my chromebook, and this thing is a ssteaming pile of regurgitated dog bile. if theres one regret in life.. buying this thing.. even dual booted i still can't process the zips or compile them properly, maybe i need to find out how to build a zip file from scratch and comepile the corresponding stuff myself in small hopes it'll work on this chromebook
and yes, never again will I use that. it worked don't get me wrong. but then it decided to deodex my system to oblivion.

s,
hey that rhymed !
your alternative is to use a usb thumbdrive and an otg cable , else nada.

I'm gla you have a sense of humor, thank you hun. looks like i'm tabletless until i go back into town in two weeks ): i suppose till then i will tinker with it some more and unlock the universe, or find a way to convert zips that are made for windows or mac and be able to convert it to be able to be used and transfered unto the phone. Chromium os or chrome now has ADB for chrome as an extension but very iffy, has 3 options to screen record/screenshot and terminal. i was able to use vitural box for about 2 hours and force odin to pretend i was on a widnows enough to orignally root, then it crashed my chromebook. Maybe i've gotta achieve 88 mph first to get this thing to work? lol my chromebook "overclocked" 810 mghz.... maxx.... frequency says it can go to 2100... i think if i even try that i'd recreate the "hydrogen bomb"

Old issue, never fixed.

I started this thread: (https://forum.xda-developers.com/axon-7/help/help-loss-root-twrp-t3781054)
a while back and ended up never solving my issue, eventually giving up and living with an unrooted phone.
Anyhow I've been trying again to get to the bottom of the issue and after another day of fruitless research here I am hoping to bring it back to your attention.
Does anyone around here regularly use a mac to perform adb commands? I'd love to get some help trying to get fastboot working again.
Should I just give up and find a Windows computer to do this?
Thanks for reading

That guy was horribly wrong and sorry you had to live with an unrooted phone for so long. But in newer versions of Nougat (i think B32 or B35) they removed fastboot and you could not boot into it. I have a way of being able to install TWRP here without fastboot (assuming you're on an Oreo bootstack, otherwise you can do almost everything in that thread except use a TWRP for Nougat instead). I haven't tried this, but if you have stock recovery, try downgrading to Nougat B19 by using an official SD card update and using apply update from SD card in stock recovery. Haven't found an official SD card update for you but I've only done a little bit of searching.
edit: ive only found B19 Nougat full image , but here: https://mega.nz/#F!kYtRAJjJ!5tD1zPpo0nw2tJwhANA9pQ!tNsQhD5Y
download A2017U-7.1.1-B19-Full-326200B1901A2017UV1.1.0B19.zip and extract it and put update.zip in your sd card. boot into stock recovery and use apply update from sd card and select it. hopefully it works and it will downgrade

Thank you so much for responding.
So I finally went out and bought an sd card yesterday to try this and I am having no luck.
I tried unzipping the file, but it just creates a duplicate zip file so I simply tried installing the whole package.
Wether I try and install via sd card or via sideload/adb I get the same "installation aborted" message.
This is so frustrating. All I want is to root again! I'm trying to get this phone to last me as long as I can before replacing it.
Doing this all on a Mac, fyi. Not sure if that changes things. Since we're not using EDL or Axon7toolkit I assumed it doesn't matter, but there is a lot that I don't know.
Thanks for any help that you're able to provide!

If it's saying that error then it's probably not letting you downgrade.
Also this might be slightly more difficult since you're in a Mac. Can you get access to a windows machine at all? This is why I hate macs

So what would be the reason that it wouldn't let me downgrade?
I've always used a mac and always managed to find an answer. Sure, toolkits don't work, but using fastboot and adb and doing it that way always has. Now suddenly no fastboot and I'm screwed... I don't really have access to a windows pc.
I just find it hard to believe that it's simply not possible on a mac.

Yeah fastboot screen was removed in newer versions. But that's at a software level of the phone. On your computer, the adb and fastboot commands are universal. It's usable on Mac, Linux and windows. The tools used for the phone like miflash or axon7tool are made for windows though and you kinda need those to fix bricked phones. There's a way to force push the twrp image into the recovery partition via adb but I don't know what the name of the recovery partition is

@alajoy: You can give yourself access to a fake Windows on your Mac. It's called a virtual machine. VirtualBox is one free software that can do this. Pretty easy to use, you install a virtualized Windows that you can boot into. Then you can run all Windows-based tools out there. It's also easy to share a USB port with the VM. Then flashing tools can access it. I run Linux as my main OS on a Sager gaming laptop, this is how I flash my A7 and Samsung phones. It just works, and reliably. I do also have a real Windows 10 installed on a partition on the same PC, but that is only for gaming and I never, ever allow it to connect to the Internet.
@Teet1: The literal name of the recovery partition is exactly that, recovery. And that is what most Android devices call it, regardless of manufacturer. It doesn't matter whether it is TWRP or ZTE stock recovery, the name is the same. It can be accessed via the paths:
/dev/block/platform/soc/624000.ufshc/by-name/recovery
/dev/block/bootdevice/by-name/recovery
/dev/block/sde14
On other devices the path may be different (but the 2nd example above will work for most), but the name is usually the same.

By name i meant the path, are you sure that's the path for our device? I tried that once and it was not that. Either way he is able to do it

@Teet1: Yeah, I'm sure, but not on all 3 paths. /dev/sde14 may be correct or not, depending on firmware/boot stack that is installed (or the presence of a vendor partition, which might change the paths). But the other 2 should be as I listed.
Just open a root file manager and see for yourself. I use Total Commander, which also shows symbolic links (the one with "bootdevice" in the path is really just a symlink to 624000.ufshc). Getting the recovery path from the example with "bootdevice" in the name should also work on almost any device running Android, and will generally point to the recovery partition. You can see the paths in TWRP too, but TWRP doesn't show symlink (but you should be able to see them if you use the right commands in any terminal, like TWRP's terminal).

6T keeps 'crashing'

So I just picked up a clean used International 6T. Was going through the root and update (I did the Android 10 update through Oxygen Updater) process and all that, things were going great, then out of nowhere they weren't and I had a complete black screen. I've literally been up all night trying to fix this thing, then again out of nowhere it actually boots, and I was able to use the MSM tool to restore it to that earlier version, then proceeded to get back up and running again.
Thought, phew, dodged a bullet. Nope, after getting rooted and TWRP installed, transferring a bunch of files over from my old SD card and restoring apps through Titanium (again, everything was going great again), and yet now all of a sudden I'm back where it all started earlier, stuck at the 'The boot loader is unlocked and ....' boot screen, it just hangs there, I can reboot into recovery just fine, but no operating system.
I'm literally about to pull my freaking hair out and try and sell this thing if it's going to keep doing this, I've never had a phone act like this one has (prior phone was a Nokia 8, headache). I have friends/family who haven't heard from me in a couple days now because I'm out of a phone and I need to get this thing working stable.
Can anyone help or shed some light on why this has happened again? I didn't update to 10, left it on the last stable Pie (begrudgingly), didn't flash any custom rom or anything, it was restoring most of the titanium apps just fine (some just hang there, not sure what that's about) and now I can't reboot into the os. To say the least I'm beyond pissed and annoyed at how much time I've lost on this thing.
Please please please help if you can, I'm not a newb to rooting (already rooted this one twice) but I don't know what to do at this point.
Thank you in advance, let me know what/if any info is needed.
Edit: I think I know/understand partially that magisk is to blame for this and reinstalling it fixes it, though I just did that through TWRP and it's still stuck on the boot screen.
Edit: Yup, right back where I was, device now shows as HS-USB QDloader..... in device manager. What gives? I have to use the MSM tool again? Why? Why is this happening...I've never had this much trouble with a phone

Try a clean install. Don't root and don't restore the titanium apps. Install them fresh. If your problem persists then it may just be hardware. But something you are restoring may be causing the crash due to the way it is trying to restore the app data.

I had similar problems. For me it was my self-created magisk module that ran without problems under Android 9. As it seems, there are also problems with modules from the magisk repo.Could be the case with you.

Clean install of the apps, after doing another MSM restore? And trust me, I won't be installing ANY other magisk files other than just the magisk.
Is there any way to save all the work I just did though without having to start over again via MSM? I'm guessing not....sigh

Grrrr...ok before the MSM tool worked, the phone was just unresponsive. It's back at that stage where the MSM tool times out and doesn't do a darn thing to save the phone.

I swear this thing is all over the place, now I'm in the bootloader, yay. I guess I'll try a wipe in TWRP and start over.

One thing I forgot to ask, is magisk the ONLY option available for root?

The question would be, how did you root.
TWRP is not working when you don't follow the instructions which involves OldKeysFlasher.zip.
Otherwise you have to flash Magisk with a patched boot image, be sure uyou have one for OOS 10 Stable.

I hope that anger is directed towards yourself because you can't hold the device or its manufacturer responsible when you get into the flashing game.
If you had done some reading, you'd know that TWRP doesn't play well with Android 10 and upgrading from 9 takes a very specific procedure. There's a dedicated thread for it even. Happy searching. You may also want to take a peek at my posting history for some pointers.
One more thing, are you absolutely sure it's an international device and not a converted T-Mobile version? Because that can cause a major amount of troubles.
Wrapped with delicious Fajita [emoji896]

I'm well aware it's my own doing, part of the frustration is having too many sources of information all claiming they fix a 'thing'. There's the "fix it with fastboot" camp who doesn't like MSM, and there's the MSM camp that helped me the first time. Phone is currently dead/black screen, going to try MSM again, and will check out the info you provided.
And I'm sure, double sim tray, does not flash a pink tmobile screen and/or no branding of any kind on the phone related to tmobile.

Just remember that dual SIM trays are easy to get and if it's been converted from TMO to international version there will be no indicators till n you try to flash A10. Best bet would be to treat it as a converted TMO, if it is the info in recovering and flashing a TMO device will work and if it's truly an international version it will work too. Best of both worlds.

I'm 99% certain, by the label on the box, etc. Regardless, I'm to the point now that I can't even get it to boot to TWRP after 'fastboot flash boot twrp.img', it just does nothing and when I try to boot to recovery it bounces right back to bootloader. I've been trying all afternoon to fix it with no luck.
Was android 8/oreo good on these phones? That was my sweet spot and I'm just gonna downgrade if possible, there's too many things I don't like about 9 and 10.

Onn 7" Model 100026191 TWRP Development

Alrighty... So I'm in the weeds here after going through three variants of the Samsung JPop (Which have bootloaders locked up like Fort Knox) and decided today to break down and dish out $59 for this bargain device. First thing I did upon getting it home was fastbooting it, and was able to unlock the bootloader with no issue. (So easy, a caveman could do it)
I've read just about every thread in here and though there seems to be TWRP support for quite a few models of the Onn tablets, I didn't see this one in here. Right now I have a throwaway laptop which is installing ubuntu for building TWRP for this device. Now, I have NEVER built TWRP. But I have plenty of free time, ambition, and am willing to learn. I have the basic guide to building TWRP open elsewhere. I will take whatever help I can get on doing this, big or small. Building a basic TWRP image should be easy enough, but the guides don't really go into device specific details (as expected), so this is where I could use some veteran help.
Device Specs:
Model: 100026191
Out-of-the-box Android Version: 11
Display: 7" 1024 x 600 Resolution
Processor: 2.0 GHz Quad-core CPU
RAM: 2GB
Cameras: 2MP front & back
USB: Type-C

Ubuntu just finished, and I am getting the build environment ready as we speak. Will keep this thread updated with progress and hickups that may occur along the way. Wish this noob some luck!!!!

Alrighty, so here's what I've been able to come up with as far as more detailed system information. Sorry for the late post, had trouble getting wifi working on ubuntu but got it going.
I suspected a MediaTek CPU and was eager to do a readback with SP Flash Tool, but as you can tell from the provided screenshots, it's actually a Cortex-A53 CPU. my goal here is to some how pull my stock recovery out of here. I thought about dd'ing it but someone in another thread advised against it. Does Onn have stock firmwares hidden away in the internet somewhere? Or is there another tool I can use to pull recovery?

Good evening guys and gals. New day, new opportunity. So i'm still stuck at pulling off boot and recovery from this tablet. I used
Code:
/adb shell cat /proc/mtd
to no avail. Permission denied just like with dd.
Today, I got the MTK droid tool and hooked the tablet to it and got these results. Still no scatter file, still no progress on pulling these partitions. (I apologize for my dumbness yesterday, this device is in fact MediaTek)

Alright. Eighty of you have clicked in this thread, zero of you show any motivation to do anything to contribute. You guys must hate this tablet because I went through this entire board, and each thread that even mentioned this model were left with no response. I just want the boot and recovery partitions off of the stock tablet. I am willing to do the rest. I said before, I'd take any help I could get but since this device is "so" insignificant, I'm not trying anything else on it.
I don't know if you guys dodge this device because it's Android 11, or what. But the least you veterans could do is either tell us it's not going to happen (given that you tried), or give us some other ideas we could try. Hell I'll paypal you enough for you to have the device in your hands in order to help. But that's where I stand. Moderator can lock this thread if he wishes. There's nothing else I can do for this device at the moment.

guess i'll return it to walmart
was hoping to root it easily with twrp
just gonna go grab the 8' if this is how it ended for the 7'
thanks for the help though!

I need a firmware for the 100026191

Alright. Eighty of you have clicked in this thread, zero of you show any motivation to do anything to contribute. You guys must hate this tablet because I went through this entire board, and each thread that even mentioned this model were left with no response. I just want the boot and recovery partitions off of the stock tablet. I am willing to do the rest.

I have the boot and recovery images if you want them.
I unfortunately accidentally deleted the original boot image, but I have a magisk patched image still present.
I can walk you through the process of extracting the original if you would prefer that, it's quite simple, I just don't feel like buying a second Onn tablet at the moment.

Just note that if you want to extract the original boot image, do NOT flash the Magisk image, it will permanently erase the original boot image. There is another way, I can walk you through it.

I oicked up one of the gen3 tablets. Do you think your way of pulling the boot image would work on it?

My way of pulling the images should work on any Android device that ships Android 8.0+, however if you got it brand new, don't update it.

Factory reset it if it downloaded an update, then disable OTA updates before enabling Wi-Fi.
You can run `adb logcat` while the update is downloading to find out where to download the OTA, and dump the boot partition from that.
From there, if you install Magisk, you can dump the recovery partition with `adb shell`.

Ok I will have to reset it then go from there. Do you have a guide on how to pull the image?

When doing first time setup, don't connect to Wi-Fi.
Enable Developer Settings
Disable OTA Updates
Enable USB Debugging
Connect to Wi-Fi
Connect the device to your computer
Run `adb logcat > ota.txt`
Reenable OTA Updates
Go to Software Updates and start downloading the Android 12 update (If it's not the Android 12 update, disable OTA updates again after this one finishes installing, then try logcat again after rebooting)
Search for a link that looks like `https://android.googleapis.com/packages/ota-api/package/827ee737174e0e8f761bcaeb12738221a924c810.zip` in the logcat.
Put the update link in your browser, and download the zip file.
Extract the zip file
There's your boot.img, very conveniently.
The update link I have provided is for the 100074181, the 3rd gen Onn 7, if you happen to have that one then go ahead and just use my link.
Though update to Android 12 before actually using that boot.img with Magisk, it won't work with Android 11.

After you're done with that, and you're rooted.
`adb shell`
`su`
`dd if=/dev/block/by-name/recovery of=/storage/emulated/0/recovery.img`
Then connect your tablet to your PC and enable file transfer in USB settings, then just pull recovery.img out of your tablet and you have the recovery image.

I will look for it. Saved it to a USB drive and of course it decided to be stupid and it is repairing now. Slow going but as soon as it gets done I will look to see if it survived and if so I will get it uploaded.
