Thought I was doing so well; tablet won't boot to OS - Shield Tablet Q&A, Help & Troubleshooting

Hey folks; I'm hoping I can get some advice or pointers, or maybe just a slap upside the head with something I've missed.
I have one of the original Shield tablets, and played around with it quite a lot, installing various custom ROMs from the marvelous directions I've found here. When the battery thing happened, I submitted the required info and happily received my new tablet. The original was rooted and customised still, kill-switch averted, and I had two working tablets. I gave the new stock one to my wife.
But then, about three months ago, I was playing with mine again installing a newer ROM than the one I was using (I *think* I was going from an older Bliss rom to one of the Cyanogen), and ... Something Happened (tm). The tablet rebooted in the middle of everything, and now won't boot to an image.
I'm on Windows 10 now, and had some fun getting the drivers working, but they seem to. I can communicate with the tablet through Fastboot, but ADB doesn't see it. I've flashed several versions of TWRP to the tablet, and can boot into that recovery - both through Fastboot and the tablet's power+vol-dn buttons. I've used TWRP to flash several different ROMs, and it *appears* to work (there are no errors), but when I reboot the tablet .... nada. Nothing but the Nvidia boot screen for days.
So now... what have I missed? I'm a little reluctant to flash a stock ROM, but I'm at a loss. I used to have more time to fiddle and figure, and I'm afraid that my impatience is going to kill the thing.

Format system and data see if that works

You need to have the latest bootloader to run the latest roms.

so you wan t your "burning" tablet set again stock?
Did you read about "recovery images" for shield tablet?
If fastboot is working you can flash the recovery image and all will update to the latest(blob,system,boot, etc)
flash latest twrp for shieldtablet.
after that use the nomoreota.zip to prevent the software brick from nvidida

No, I don't want it stock at all, I was just worried that was my only option to get this thing to respond again. I was running BlissPop v.somethingorother, but wanted to update. That's when things went awry.

Right, well it looks like I've got this thing going. I could flash TWRP 3.1.0-0, but not any 3.1.1. Cyanogenmod 12 worked. Reading up a little more (it got slow at work for a couple of days...) I flashed the firmware to 5.0, and could now install TWRP 3.1.1-1! Then I could install (in this case) Lineage 14.1, which *almost* worked. It booted, but there's no wifi.
Then I found a suggestion - I think it was on these forums somewhere - and restarted. Wiped all data again, flashed Cyanogenmod 12, no gapps. Restarted, checked everything including wifi, and is good. Rebooted back into recovery, performed a factory reset, then installed Lineage 14.1 and gapps. When it rebooted, everything is working!
So. Firmware. Huh.
Thanks all.

do not know if you need the bootloader(blob) from nougat to boot up, that lafester told you. but that sounds plausible. skooter says something from re-formating. so if you tried that all and nothing changes? cache and data partition you wiped also, so it has to be work for my understanding.
went always stock, so can t help you..
but you can use recovery images > twrp > bliss/linage. no need to boot up stock?

(Solved) Soft-bricked, but unable to flash anything but CWM.

Hello, I seem to have soft bricked my tf700.
​I flashed a newish pacman nightly in CWM (after wiping data/cache/dalvik cache), which completed with no errors, then I flashed the corresponding GAPPS. But my device became stuck in the pacman boot intro.
​So I tried flashing slimkat which led to my device not getting past the first bootup screen (where you can enter recovery if pressing the corresponding buttons).
​After this screw-up I stupidly hit the wipe data button on the bootloader. I then tried doing the method of using fastboot to erase system, cache, and all that so I could flash system blob of the newest asus US SKU (that is correct for a US bought tf700 right?). Either this or wiping the data caused me to have a different bootloader as pictured below as I no longer have the android button and it does not ask me to press volume up to access recovery (the only way to access recovery is by hitting the wipe data button in bootloader).
​I can still fastboot flash CWM, but trying to flash TWRP does not work as it finishes but going into recovery causes the tablet to just restart. Trying to flash asus stock as above would always give me an error like the one pictured below. Similar errors occur if trying to flash any rom inside CWM via an external sd card.
​I do not have access to adb as i believe i dont have usb debugging enabled since the pacman rom or any other rom did not ever start. It just gives me the device not found error even after manually installing the drivers on two different computers.
Cant seem to get these pics to load, but copying the url and pasting it works.

You probably flashed the wrong Rom. Try flashing the >right< stock Rom and go from there. Double check everything you flash.

Whats the "right" rom here? Talking about the original asus stock rom? I have now tried the the pacman nightly, pacman release, slim kat release, clean rom release, an ICS asus stock rom, and two different versions of the jellybean asus stock rom. These were either done in CWM via internal sd card, external sd card, or done through fastboost flash system blob and flash zip.

As far as i know, i have installed the stock rom, or atleast multiple versions of it with no success as it gives me an error stating something like staging or system when trying to write it.

Hmm, I'd Download a stock Rom for the device offline, take on the sd card and put it on there real quick and try to flash that, if not, you probably bricked your device. I wouldn't know how to fix it beyond that. Ask the dev that made the Rom were everything that went south and an email to cwm wouldn't hurt either
I am also not sure if I need to have my external sd card formatted a certain way or download a specific CWM to allow flashing the stock rom. Ive spent over 10 hours trying to figure this out, very frustrating.
I have run CWM 6.0.4.6, CWM 6.0.4.7, and older versions to see if I could flash the stock rom with no luck. I have also tried different versions of TWRP but they always hang and reboot my tf700. I get errors ranging from status 6, status 7, cannot mount data, cannot mount staging, and cannot mount system. I am completely lost on what I can do. I have even tried a seperate sdcard to see if maybe the one I was originally using was bad with no luck. GG :/

You gotta stop flashing stuff and slow down!
During all of this you never posted your bootloader version, so you may have been on the wrong bootloader to begin with - who knows.
When you hit the Wipe Data in the bootloader menu you caused the BL do write a wipe data command to the misc partition, causing the tablet to boot to recovery each time you booted (I'm guessing here) and then interrupting it. Usually, with CWM installed, it eventually sorts it out and executes the wipe data command, but that takes hours! You just have to leave it alone.
Hard to tell where you are now since you flashed all kinds of stuff since then.
Can you still boot into the bootloader and have a fastboot connection?
What's the BL version number?
If you boot, what does it boot into?
The picture links are broken - at least in Tapatalk. Post them again?

Yes, the pictures are broken. You can still copy paste the url though. Couldnt figure out why it wouldnt work.
The tablet boots into the first screen that states it is unlocked, but does not go any further.
There is no bootloader version on the top left when holding down power + volume down.
I can still get to the place where it allows me to wipe data or fastboot, but the android icon to boot into android is now gone.
adb does not recognize my device even after manually installing the drivers, but fastboot works fine.
Is there any other way to find my bootloader version?

Maybe you want to edit your post with the urls then.... Makes it easier for people trying to help...
You're seriously messed up, I think. I see a USB icon in there which would indicate that your bootloader is ancient. But then it says: "starting USB fastboot protocol".
Is that after you selected the USB icon?
Anyway, I think you're only chance is buster99's method to get it back. Did you try that already?
http://forum.xda-developers.com/showpost.php?p=44244313&postcount=12
Naturally you have to extract the system blob from the 10.6.1.14.10 US Asus firmware, but then you can try to fastboot flash it with buster's method.
Good luck!

Its starts the usb fastboot automatically if no input is selected. I had a different bootloader up until i tried that thing that buster did. It always gives me an error like cant write to system or something if i try it.

Which blob did you flash with buster's method?
I'm afraid you flashed something totally incompatible with your tablet...
You did not generate your nvflash blobs sometime prior to this, did you?

I flashed the asus stock rom downloaded from their website. The US version as it was bought in the US (right? 0.o). I hadnt heard of nvflash before trying to install a rom so i did not make a backup.

Right stop flashing random stuff - you have combinations of JB4.2.1, JB4.1.1 and ICS 4.0.3 just listed there.
Let me put a call out to @lj50036 who may be able to save you but if you have messed the bootloader up with no nvflash backups you are not going to be happy with the result. If you can still get to the bootloader screen then he can perform miraculous superhero acts and *maybe* save your device.

Issues with TWRP 2.8.6.0: Flashing a different Modem

It's possible this is also somewhere else, but I am having trouble finding it....so I gave up and figured I'd ask.
Okei. I started with TWRP 2.8.6.1. So from my understanding flashing a modem does not work in versions of TWRP newer than 2.8.6.0. I get that, and so I decided to downgrade. However, that seems to be the version that I am unable to get working. I've attempted to flash the 2.8.6.0 recovery via fastboot. Everything says it's good in my terminal. So I go ahead and boot into recovery, but my phone goes to a black screen for a moment and then reboots into OS. I tried a different method, via the app from the google play store. It tells me that there is an error of some sort, or that I already have it installed. So I used the google play app to install 2.8.6.1, which worked flawlessly. So now I am back where I started.
Is there some trick to getting specifically TWRP 2.8.6.0 working so that I am able to use it to flash a different modem? Will using an even earlier version yield the same results? Or am I better off doing it via fastboot?
Thank you for your time <3

I too have experienced exactly what you describe and have yet to find a solution. I own 2 OPO's, plus I administer one for a friend who purchased one based on my recommendation. The oldest one I own which was purchased 4 months prior to the others has worked perfectly with any recovery or ROM I've installed on it. It has TWRP-2.8.6.0 installed and has no problems flashing any partition from recovery. My newer handset and my friend's both refuse to boot into recovery with that version installed. It doesn't matter if I flash from fastboot or from TWRP itself. I have no idea why this phenomena occurs on some of these devices, but it makes administering them a more time consuming pain in the ass. I'm going to try Phil's recovery, as was suggested, as a workaround, but I'm dumbfounded as to why the inconsistencies exhibit themselves on particular devices.

Unfortunately, if that is the same one from twrp's website it isn't going to do me any good. I already attempted that through fastboot. 2.8.6.1 works flawlessly. 2.8.6.0 seems to bootloop once and then toss me back into the OS. Thank you though, I appreciate it.
Had the same problem tried to flash back to 2.8.6.0 via TWRP and didn't work and seemed like recovery had disapeared so used TWRP App to install 2.8.6.1 booted into recovery then rebooted and tried to downgrade to 2.8.6.0 but got a message about same recovery, rebooted phone tried again and it installed no problem.

YOG4PAS2QL bricks my OPO

Hi
Since updating my OPO to YOG4PAS1N0 I couldn't reboot my OPO. Since the last update it won't even boot any more. I've reflashed to stock 4.4.4, installed every update and had the same issue. I even tried to flash the zip true recovery, but i got an error while doing it. So, after three times of updating, I'm back to square one.
After going back to stock I have to factory reset in recovery, otherwise the OPO won't boot.
But of course I'd like to install Lollipop (and later Marshmallow). What can I do? I have a Mac with OSX 10.11 and a laptop with Windows 7, so I'm able to use both.
I did the flashing on my Macbook with the Toolkit found here. But I don't think there's an issue with this, as it uses the terminal. It's just easier then to type it all myself
Thanks in advance.

It'd help if you actually posted what errors you're getting, without information like that it's virtually impossible to troubleshoot. Anyway, your best bet is probably just to flash the stock images with fastboot. Back up anything important first as this will wipe your device. See section 8 of my guide:

I've tried the first, didn't work. I've tried flashing 11S and started upgrading. I didn't have issues until 12.0. When I got to 12.1 I couldn't reboot (but I could shut down and boot). With the latest update I couldn't even boot normally.
Anyone has some idea?

Not sure if its a language barrier but first of you are going to have to supply more information than that. Secondly what have you tried to fix it and especially since there are tutorial out the waaaaahzooo in here on how to repair your "bricked" phone.
Please research make some attempts and if any issue please document in full what your issue is. I guarantee you though whatever it is someone here has gone through it already so search thorough

What I have tried is on page 1 of this thread.
I tried to install 4.4.4 with a flashable zip and then installed all updates. I installed the 5.1.1 zip. I installed the fastboot 5.1.1 and 4.4.4 and installed all updates.
Now I'm on 5.0.
On the last update I couldn't update reboot or boot anymore. The update before that I couldn't reboot, bu I could boot.

XT1254 Won't boot to system after factory reset

Hi,
I have a VZW Quark that's been unlocked with Sunshine and rooted and running fine on custom ROM's for a year. Today I did a factory reset and complete wipe and reinstalled RR Rom and GApps etc. However, on reboot, it only goes back to recovery (TWRP 3.1.1-0). I faced this the last time as well and managed to find the fix by googling it but can't seem to get to it now. It was a quick fix and then it booted to system fine and I cannot remember it. Can anyone help! Thanks.

Someone else had this issue and they solved it by flashing the latest @bhb27 modded TWRP. You say you have TWRP 3.1.1, but is it from the TWRP website or from @bhb27? Flash this one below to make sure.
twrp-3.1.1-mod_2-quark.img
https://androidfilehost.com/?w=files&flid=39562
Once they flashed it, they were able to boot to system, then they booted back to TWRP (on purpose) -- and then upon subsequent reboots everything was fine.
See here:

@bhb27 Im face a problem, since I do a clean install build 08/23, when my phone restart, it always boot into TWRP, and I need to boot to bootloader and press START to start system normally.
Maybe Im doing something worng due the install process, (full wipe include internal storage, flash Crdroid, flash Gapps, reboot), I try to flash boot.img and new TWRP 3.1.1 recovery.img, but got a same results.
Please help, thanks a lot.

You may not be using the TWRP made by me, check TWRP thread and use the twrp-3.1.1-mod_2-quark.img version that is in the afh mirror folder if you are not using that... also try to update the ROM as 8/23 is one month old on updates...

No OS installed in TWRP

Hi guys
I was trying some of custom rom on my OP6 and I wanted to go back to Oxygen OS. So i did a clean installation with system wipe and i flashed the last full OTA update. But since i can't boot to system anymore, TWRP always displays that there is no OS installed despite the fact that I've tried several rom . Is this the first time it's done this to me how can I fix it?

The best suggestion I can give you is to flash stock oos with TWRP, reboot to stock recovery, without flashing anything else, wipe data from stock recovery and startup system.. if it is working you can flash back TWRP and magisk if you need it
Just be careful because at your point is easy to lose all of your stored data

If you wipe system, then flash oos ROM, TWRP will think there is no os. You can just ignore and boot.
Wiping system then flashing any time will make twrp display "no os installed" it does this because it hasn't created files for twrp to check if you have a ton installed. Flashing twrp then rebooting to twrp fixes it.
Reboot to stock recovery?

Hi, need a little bit of support, since I'm new to this as well. I was in a working OOS open beta 25/28, but then I think I flashed the wrong zip (OOS 9.0.9?), and I was not able to boot to system. It kept going to "bootloader unlocked" screen and custom recovery. Currently in TWRP blu_spark 3.3.1-x v. 9.109, and it's showing me no OS installed when I attempt to reboot. I haven't rebooted to system yet.
All the folders in my /sdcard is gibberish... if I try to push a file to it, it says "Required key not available." I did remove all security/passwords from my phone before doing any updates/backups.
I completed a wipe cache/dalvik/system via TWRP, and flashed the OOS OTA stable Android 10 zip downloaded directly from OnePlus Support. Considering this situation, do you still think it's safe for me to reboot to system? Then how do I get to stock recovery from there--is that by holding down the buttons?

No, your internal storage Is like trash cause the last rom you flashed has older security patch than oos10. Your device Is now encrypted and wont boot to system. I Guess you have to erase all via MSN tool or fastboot signed rom. Even if you wiped what mentioned above, your problem still be the data.
Fastboot method?

Thank you for replying. I'm relieved that you know of a couple methods to try.
Is using "Format Data" in TWRP an option for dealing with the encryption??
For the MSN tool, can I use this one? Tried looking around, but it's unclear. "[TOOL] MsmDownloadTool V4.0 International (Oxygen OS 5.1.5)" https://forum.xda-developers.com/on...wnloadtool-v4-0-international-t3798892/page10
I would be more comfortable with using fastboot, but am I at any risk of having lost fastboot, or can I just turn off my device from TWRP right now and hold down the buttons to get there? Afraid to move out of TWRP right now, in case I can't get back. I do have twrp-3.3.1-18-enchilada-Q-mauronofrio.img that I can run from fastboot if needed.
By "signed rom," do you mean I can simply flash one of the zips here from fastboot? "[OnePlus 6][ROM][OTA][Oxygen OS] Mirrors for official Oxygen OS ROMs and OTA updates" https://forum.xda-developers.com/oneplus-6/how-to/oneplus-6-mirrors-official-oxygen-os-t3792244

I hardbricked my device about 10 times and i was able to recovery It even from a blank screen. Btw format data Will erase all your data but also the internal storage. About fastboot dont be afraid, go under twrp reboot section and reboot to bootloader. Then go under xda op6 guide section and search for mirrors for fastboot rom guide by Mauronofrio. He pushed my ass out the **** a lot of time.
P.s. Sorry but I dunno how to paste a link via xda app. Yes, ik! It's a vert newbie thing.

That's awesome, I'm starting to grasp how much of a genius Mauronofrio is, after so many people referencing his work.
In his guide, he says, "These ROMs can't be used to update or downgrade your phone but just to restore your phone, so don't use them to come back to oreo or to update from oreo to pie." This may be a dumb question, but how do I know which zip/OOS version to flash, when I don't have a functioning OS on my phone?

I talked with Mauronofrio in pm and he said me that you could solve your issue simply flash the ROM you want and format data after flash that one. Remember that your internal will be wiped but it would happen in any scenario we talked.
Magisk, boot img?

That worked! And starstruck that you were able to check that with him. I flashed Mauronofrio's fastboot ROM for 10.3.2 and it rebooted (WOW). I clicked through the Google setup pages and checked that my data and wifi worked.
I then went back into fastboot, booted M's twrp img, fomatted data, and then installed twrp-3.3.1-x_blu_spark_v9.109_op6.zip, rebooted into recovery.
Then I think I made a mistake, because I installed Magisk-v20.4.zip. It succeeded, but now I can't boot into system anymore. Is it too late to flash the 10.3.2 boot.img?

I ended up following the guide to Magisk Root without TWRP for OnePlus 6 Oxygen OS https://forum.xda-developers.com/oneplus-6/how-to/patched-boot-image-magisk-16-7-beta-t3818853 since it was referenced by Mauronofrio's post for having issues getting his TWRP to work with latest Magisk.
Someone posted a patched boot.img for 10.3.2, so now I'm rooted without TWRP. Priorities. Now all I need is for special characters and emojis to work Will keep an eye on other threads.
I'm learning a lot, thanks so much for all your help. You pointed me in the right direction when I was not sure what the hell to do!
