[Q]Can't flash anything because bootloader freezes..Please Help - Nexus 7 Q&A, Help & Troubleshooting

[SOLVED]
I used the Wugfresh Toolkit. I'm on 4.3. Bootloader version Flo-3.05.
I unlocked the bootloader. Whenever I try root it just hangs on "booting to custom boot.img" and the
bootloader is frozen (the buttons dont work) and need to do a hard reset to get out. The bootloader
freezing also happens when I try to push anything like a custom recovery.
The first time I tried pushing a custom recovery it seemed to work but now I dont have a recovery installed at all.
Is the problem the bootloader version Flo-3.05? I cant even find that much about that version.
Please help

Hi, mentallo...
I don't have one (yet)... but I think Flo is Googles codename for the New Nexus 7(2013).
In which case, you probably should be posting here.... http://forum.xda-developers.com/forumdisplay.php?f=2409
And don't try to flash anything originally designed for the old Nexus 7(2012) on your new Nexus 7... as I suspect it will cause no end of problems.
I'm not even sure WugFresh has a toolkit available yet for the New Nexus 7.... but then I'm not a big toolkit user.
Rgrds,
Ged.

Oh my god, this is amazing. I bought this from ebay for $100 thinking its a first gen buts actually a 2nd gen. Brand New. Thanks for pointing that out. I'm flabbergasted.

No problem, mentallo...
My gasted is also equally flabbered. $100 at current exchange rates works out at approximately £64 UK pounds... which sounds too good to be true (my 1st gen N7 cost £200 around November of last year).
The new Nexus 7 differs from the old one visually (check Google Images), by having a wider bezel at the top and bottom. You also might want to check for a serial number (it's a transparent sticker on the back of the 1st gen model; I've no idea what it looks like on the new one).
But the bootloader, Bootloader version Flo-3.05, certainly suggests it's the real deal, as the official Google factory image has only been available for about a week (due to some legal wrangling between Google and Qualcomm)... so your device must have originally shipped with that bootloader. (In other words, it's hugely unlikely to be a fake).
Anyway, congrats. on a fantastic deal. Hope you can get everything working to your satisfaction.
Rgrds,
Ged.

4.1.2 OTA Stuck in bootloop

Hey guys,
I've just tried updating my Nexus 7 to 4.1.2 OTA, after the download was installed it tried to reboot and it's just hanging on the Nexus logo boot screen. I've tried to boot in to recovery mode but I just get the little android with the red exclamation mark triangle.
My device is not rooted and was previously running completely stock firmware 4.1.1, never tweaked at all.
Any ideas would be very helpful - apologies if this is a glaringly obvious fix, I haven't searched much as I'm posting from my phone.
Many Thanks
I am having the same problem but mine is rooted. So I was probably thinking I was having the problem cos it's rooted.

Do you have the 4.2.1 bootloader? or it might not work.
Don't think so, it's completely standard. Been updated from 4.1.0 to 4.1.1 when I bought it, since then only change to the firmware I've made is today downloading 4.1.2.
Did you do a manual update or was it system self prompted update?
I was notified that an update was available by my device. I pressed install now, it downloaded and the device rebooted and started installing it. Then it triedvto boot back up and failed.
if this happened and you did NOT root or unlock the bootloader, then you are eligible for a replacement. go to the store you have bought it from and ask for a replacement unit. if you did unlock the bootloader, then you have to boot into bootloader and use this tool and select 9 after installation. it should return your device to stock, providing you can still boot into bootloader. good luck!

I was hoping that wouldn't be the case to be honest and that I'd be able to fix it myself, ah well. Thanks a lot for your help
Just so everyone knows, I took my tablet back and got a new one, which when updated broke again. I got a third tablet and contacted Google directly, they told me they can't really help but try updating again, which I did and bricked my 3rd device in a row. When I called Google again they said I need to speak to Asus (regarding this issue with Android software) in terms of getting another replacement. Which means I'll be left without a device until they replace it!
Wow, the same problem as I had.
My brand new, stock nexus 7 (4.1.1) informed me there was an update so I allowed it to install it.
It was connected to the PC during the whole process.
It installed the update, but got stuck on the boot screen (the X logo). It took too long so I suspected something went wrong...
In a few minutes I was forced to learn how to do a forced restart, enter the recovery menu, etc.
But sadly nothing helped, as it ALWAYS ended up showing that X logo and would not go further. So I decided for a drastic measure and wiped the device (reset to factory settings). Unsurprisingly, it then booted fine and the new update was there.
Of course I lost all my game saves and other data... Really pissed off, but decided to swallow it for the time being.
If this happens at the next update, I'll definitely say goodbye to the Nexus. Would be a shame though, as it's a lovely device, very handy.
Just for the record, I live in the EU and the device was bought in a brick and mortar shop, and it had 4.1.1 installed.

Hi. Slightly off topic, but maybe worth mentioning : I have exactly the same problem with the 4.1.2 OTA update of the Nexus S.
What did you do, reset to factory settings?

Yes, but I had some difficulties doing it, couldn't even tell you exactly how I managed to.
I'm really disappointed by this OTA update, it shouldn't be more complicated than flashing an alternative ROM.

[Q] Nexus 7 Update Problem

Today I got a shiny new Nexus 7 32GB and was eager to get using it. Knowing of the 4.1.2 update I decided to get that installed ASAP and enjoy the benefits.
I went to Settings/ About Tablet/ System Update
There it appeared, 4.1.2 update available, so it downloaded the update and I clicked Restart & Install.
It rebooted and about a third of the way across the progress bar, it stopped, showing a green android lying on its back with a red triangle and exclamation mark on it.
I've tried updating through this method several times with the same problem every time. Does anyone know why this could be and a possible solution?
I would prefer to install this update through the device if possible without installing CWM Recovery or any other extra recovery tools.

I have also recently received my shiny new Nexus 7 32gb and have been unable to update to Android 4.1.2 - the update downloads, seems to install, but after restarting Settings still shows I've got 4.1.1.
Anyone got any idea what is going wrong?

I found a solution. The boot loader in stock 4.1.1 is different to those in the updates to 4.1.2 and 4.2 (apparently, I'm not 100% sure) and this prevents a straight forward update. As far as I can tell, the only way around it is to flash the Google stock image for 4.1.2 or 4.2.
Thankfully this is easy to do since you can use this incredibly useful toolkit to do it for you: http://forum.xda-developers.com/showthread.php?t=1809195
Just read through the instructions and make sure to backup your apps and personal files as you will loose all data!
If you choose to donate it'll let you download and install the latest stock image, 4.2, or you can just flash the stock 4.1.2 image for free and wait for the standard OTA update to reach you (which will now work, I tried it).
I chose to donate as the toolkit is superb and makes everything so much easier when fiddling with custom ROM's and backing up apps, and I prefer flashing the complete stock image of a new version rather than updating.
Hope this works out for you and helps anyone else who gets the same problem!

I don't think this is a solution that I want to try on my brand new Nexus 7. Clearly there is something wrong with it so I think I'll return it to PCWorld for a replacement. Though I might try a 'factory reset' first and see if after that the 4.1.2 update will install properly.
It's worth a try!

That's fair enough, I tried a factory reset first myself to no avail. If you do get your nexus replaced, please let me know if the update works!

I'm considering taking it back because it is not updating as it is supposed to, as it is designed to. A message comes up on the screen that a system update is available. I go through the procedure to download and install said update. The update doesn't install, though the system now says that it is up-to-date.
Bootloader? I don't even know what that is. I don't know that the problem is caused by the bootloader and neither do you. It may be a joke to you but to me its just a pain in the neck.

obviously the guy doesn't have working knowledge of ADB, rooting/unlocking or any other development terms we use to describe what we are doing to our devices.
The only jokable premise here is some nerd in his mother's basement thumbing his nose at random people because the world he lives in is so narrow it couldn't possibly comprehend the existence of someone honestly asking for advice and then doing the only logical thing he can think of to do as a consumer unfamiliar with a product at a developmental standpoint.
Not everyone wants to root. And not everyone who owns a Nexus has background experience in tinkering with electronics. I've been rooting since my Dinc and I actually want to keep mine as stock as possible. I find more problems come to me when I start messing with the device instead of just leaving it alone.

Android Device Protection on Rooted Moto X Pure

I'm in a quandary. I bought a used Moto X XT1595 32GB from Amazon Warehouse and received it yesterday. Looks like the previous owner never removed his/her Google account from the phone so when I try to run it for the first time I'm hitting the "Verify Your Account" screen The rom currently on it is Lollipop. When I went to recovery I found out that not only is it rooted but it has TWRP 2.8.7.0 on it. I proceeded to download a MM rom and flash it it, everything went well, the phone booted but still returned me to the Verify screen.
I called Amazon and explained the problem and they offered to accept it as a return. This is great but they no longer have any used ones to replace it with (32GB Black for $279). The phone purchase was a bargain and I'd love to keep it if I can bypass the ADP, otherwise I will return it.
Is there any rom or anything else I can do to get around this? The phone otherwise is in great shape. Thanks
Factory reset in recovery didnt do the trick?

If the device is rooted and contains TWRP, shouldn't you simply be able to wipe/factory reset from recovery to eliminate the security? Did you do a full wipe before flashing MM? I can't imagine that Android Device Protection would persist through a full wipe via recovery and ROM flash. Also, did you update TWRP before flashing MM? There is a newer version 2.8.7.1 here.
You are out of luck. You will have to contact the previous owner. There is no way around it.

Nope, you need to do a factory reset from the settings menu.
I used flashed 5.1.1 from 6 without doing the reset in GUI, and sure enough the device protection kicked up.
I did see a post where you can use a rom with persistent ADB enabled, use ADB to launch the settings menu, and factory reset that way. Since TWRP is installed, you might be able to use that route?

Everything I've read online says it cannot be done. I tried everything from changing recoveries, to flashing 5.1.1 & 6.0 roms, factory resetting everything etc. but no luck. Google really has this thing locked down. The link you provided however worked perfectly! I was just about to give up and send it back to Amazon but you saved the day - thank you

Phone started rebooting randomly yesterday, now stuck at Google splash screen

I'm pretty adept when it comes to adb/fastboot/flashing etc but I'm running out of ideas here.
Yesterday my phone rebooted twice on its own --- didn't think much of it (but probably should have in hindsight). Happened a third time and now all I get is the white "Google" splash screen with constant reboots.
Holding volume down does get me to bootloader --- however cannot get into recovery (same issue with google screen). Tried plugging phone into multiple PCs in bootloader mode but I get device cannot be recognized (usb device malfunction). Tried manually updating the driver - nothing.
All I want is to retrieve the photos/videos of my kids --- hoping there is some last resort that someone can suggest before I give up on this thing.
Ideas anyone?
UPDATE: Got phone to recognize via fastboot ---- still can't get to recovery. Anyway to get files?
Same happened to me, something is horribly wrong with the build(s) that came out this month as more and more people are having this exact issue. I was able to barely get mine to boot initially with the latest stock image, just long enough to upload all my pictures via Google Photos before it would freeze and go right back to the constant rebooting.
Eventually even trying a stock image stopped working, I RMA'd my phone.
This seems to be a ticking time bomb and is going to be a huge issue very soon. It's really going to be rough for anyone beyond their warranty period unless Google/Huawei steps up after they realize what's going on. I'm not even sure what I'm going to do with my phone once I get it back for fear of causing the issue again.
My bootloader is locked so I feel like I'm SOL here.... hoping for a miracle
Just got off the phone with Huawei tech support.... apparently its a known issue with no resolution currently. This is some bs
That's not gonna help you ATM but you should really always backup important stuffs. My important stuffs are also kid photo and they are backed up in my cloud AND in Google photos.
From bootloader screen, can you give us your device specs? Like emmc, date, sku,.. ?

I would grab the Nexus Root Toolkit (that's what I used for all of my resurrection attempts, makes it super easy)
http://www.wugfresh.com/nrt/
Use it to flash stock (and unlock the bootloader in the process) from Fastboot. Let it sit (and bootloop many times) afterwards as the popup suggests and see if you can get lucky with some access to your phone. Either way you can then relock your phone with the toolkit and you're ready to RMA.
The bootloader is not able to be unlocked since the setting was never checked within android itself. I let the phone sit trying to boot for a solid half hour or so just rebooting at the google logo. I think its just a brick at this point

I'm not sure what you mean, I could lock and unlock the bootloader at will, without anything but fastboot functionality.

You probably had the box ticked in developer settings or had previously unlocked it.
I believe rootjunky posted a video on how to do it with bootloader being locked
Just got off the phone with tech support again.... phone is under warranty and they are going to send me a new one. Sucks about the pictures/videos but what can you do
Is it the recent updates that's the issue? I'm still on pure Nexus 7.0
Same happend to me and someone in another thread too.i think there is a big problem with the last build

Wish I knew the cause.... as stated I was bone stock - locked bootloader and all (that's never going to happen again since I couldn't re-flash stock images because of this). Huawei was no help as to the cause other than to blame google.

Well, to be fair, this issue seems to have just started popping up with a handful of us in the last week or two.
I'm sure they are in the process of trying to figure out what happened and why with the RMA units they have. Since we were all just fine prior to this month and suddenly had this happen on various 6P phones of different ages, I'm guessing some code that Google added lately can potentially corrupt the memory/storage in certain scenarios.
This is an escalating issue

Have you requested RMA? The same happened to me too last monday night just browsing Chrome, but it isn't just the build people have in common but also the TWRP version 3.0.2-1, so everyone with their 6P still running, update your TWRP and change your ROM it sucks being a week without your phone besides losing all your files :crying:

Soft Brick - Sideload ADB OTA Signature Verification Fails

I'll put the long story below..but spare those that don't want to read. The short is, I'm not able to ADB Sideload the OTA images as it always fails to verifiy signature at about 40-47%. I've searched many places and not found a fix. So I'm hoping the genuises here at XDA which I frequent can help.
The long story. I've flashed roms for many years. My current device was the Nexus 6p. Running XE Rom I think it was. Flashed an update all was well, but my sim card would not show up. I was on MetroPCS and remembered needing a different radio. Flashed that,still no sim. Decided I'd go back to Stock since those had been updated to 8 by now. Flashed the OTA and followed some steps by another thread on XDA, one of the last was locking the bootloader. I had not booted up so I didn't know if my system was working. My big mistake! I locked my bootloader and don't have a system to boot into so I can enable OEM Unlocking. So now I only have adb sideload, can't flash individual images through fastboot! I think it can be recovered but for some reason the signature verification issue keeps coming up no matter what cable or PC I use.
If anyone has any thoughts I'd love to hear them. I have since moved to a Hauwei Mate SE and am pretty pleased but will not be a flashing phone I don't think. I loved my 6p and it still had lot's of life for me. I hate to sell it for parts at this point.... Thanks for anyone willing to chime in.

I was on MetroPCS and remembered needing a different radio. Flashed that,still no sim. Decided I'd go back to Stock since those had been updated to 8 by now. Flashed the OTA and followed some steps by another thread on XDA, one of the last was locking the bootloader. I had not booted up so I didn't know if my system was working. My big mistake! I locked my bootloader and don't have a system to boot into so I can enable OEM Unlocking. So now I only have adb sideload, can't flash individual images through fastboot! I think it can be recovered but for some reason the signature verification issue keeps coming up no matter what cable or PC I use.
If anyone has any thoughts I'd love to hear them. I have since moved to a Hauwei Mate SE and am pretty pleased but will not be a flashing phone I don't think. I loved my 6p and it still had lot's of life for me. I hate to sell it for parts at this point.... Thanks for anyone willing to chime in.

First, if i understand right you tried to flash OTA over custom rom to return to stock?? To go to stock you must flash full system image, not OTA.
And second, why the hell did you lock the bootloader??...you dont lock the BL unless you are 100% stock..
I know i didnt help you much, but if your BL is locked, dont know how to help...maybe someone else know how to unlock it again
Meanwhile read this guide,it will help you to understand some things:

Oh believe me my head hit the wall for sure! I got careless and wasn't thinking straight. No reason to lock the boot loader except it was on a list of steps to get back to stock..and I guess it was late! doh.
There are lot's of posts/videos I've seen that should allow what I'm trying to do with sideload adb but mine keeps getting a signature verification error. Each new full version of a release 7.0 8.0 etc..has the entire rom, images etc. So your suppose to be able to flash those even though they are OTA updates... *shrug*
It's a blur what I did exactly in some areas. I at one point may have tried to flash the set of Stock IMG files as well. But for sure now all I'm left with is a locked phone with who knows what on it! Stock recovery...some form of 7.0.0 that has NYC as letters...that I can find NOWHERE! on any official releases...
Prob trash, I really want that night back..lol.
