[Q] Did I brick my Nexus 4?

Hi,
Last night i was playing with my N4 (with some root applications) and an app asked for a reboot. I just pressed yes so that the phone will reboot (I have done this earlier without any issues). Suddenly the device doesn't boot up. My N4 is stuck at a black screen. While trying to boot up, the Google logo appears and then a black screen. It doesn't advance to the 'X' logo. I'm running on stock, rooted phone (used N4 toolkit by Wugfresh to root).
I'm able to boot into recovery although. I tried all the possible means, wiped cache, dalvik cache, did a factory reset, backed up the system and tried to restore the same. Nothing happened.
Then i tried the "Back to Stock" option in the N4 toolkit and chose the option "Soft-brick/Bootloop" to recover my N4. These are what happened:
Downloaded the 4.2.2 image from Google servers and tried to flash in the device with prior instruction from the toolkit. Everything went fine until the flashing process. In the last step the CMD window opens up saying it is unrooting and flashing stock and immediately it'll bring up a complete message saying the flashing is complete and to wait until the device boots up. But nothing happens again.
I tried the automatic flashing and on the downloading window it saying download failed and hash checks failed meaning its not downloading.
I searched all the possible threads in a day to find a similar problem but in vain. I'm not a noob but i'm too lazy . But i would do anything to bring my N4 back to life. Anyone please show me a direction.
In short:
Status: Soft-Bricked (guess so), black screen after Google logo
Version: Stock 4.2.2 (rooted+busybox+supersu+twrp)
Able to boot to recovering: Yes, bootable to recovery and bootloader.
Tried Nexus toolkit recovery: Yes but in vain.
Gave up: No and never, I'm searching and searching for answers and I'm worried if I'll end up in a hard brick. :crying:
Guys, please help.
Thank You!

I'm just taking a wild guess here - I'm not responsible if anything bad happens, and you might want to wait to someone else seconds my suggestion in any case (although I can't imagine things getting worse as long as you flash N4 stuff). But have you tried flashing a new boot.img/reset kernel from recovery or via fastboot/toolkit?

Err...nope I haven't tried any and will wait until someone seconds you. Meanwhile I have wiped off the ROM through the option in recovery. Still will I be able to do what you said? Also if could direct me to a "how-to" thread would be great. Just that I don't wanna mess up again.

Also, is there a way to transfer a ROM to N4 through fastboot? So that I can install the ROM through TWRP.

No, my suggestion would require that the ROM is still on the phone, so you should restore your ROM prior to my suggestion. And I'm by no means an expert (therefore the disclaimer), but I *think* that since it's a bootup problem, it could be solved by flashing a new boot.img (which is essentially flashing a new kernel to the system).
But yeah, let's see if others think this might help, haven't researched it, is at work right now. Just throwing in a suggestion, that's all...

I *think* (again, I'm totally not sure about this, as I haven't tried it) that you can sideload a ROM via zip file from recovery, but since I haven't tried it I'm not sure - can anybody confirm???
EDIT: Chromium's suggestion is better, by pushing the ROM.zip to the device and flashing from recovery (check md5 first, just in case).

Yes there is. Your nexus is not bricked and this is why you shouldnt use toolkits to do things. This is honestly an extremely easy and simple fix. Use adb to push a rom onto the n4.
Code:
adb push \path\to\rom.zip /sdcard
Boot into recovery, do a full wipe, and flash the rom.

You said you downloaded the Google images.
Just boot your phone into the bootloader and run the flashall.bat that is in the Google image folder.
Note this will probably fully wipe you're phone in the process

Okay, thanks guys. I'm on it. Will let you know when I'm done.

That same thing happened to me once. I had to extract the google file and look for the 4 img files(bootloader, system, userdata, recovery) and flash them with toolkit manually and it fixed it, but it erased everything on my sd

I tried to load the file "occam-jdq39-factory-345dc199.tar" into my phone using the ADB sideload feature in the toolkit. I don't have the SDK installed hence I depended the tool again. But now the tool only loads .zip file and not .tar as the one that i downloaded. Am I doing it right?

K if you have a custom recovery installed, there isnt much you need to do to fix the issue.
First setup adb/fastboot by reading this
Then boot the phone into recovery, and plug it into the computer. Open a new command prompt window and use adb like this:
Code:
adb push \path\to\rom.zip /sdcard
Then you can unplug the phone. From recovery go to the install menu, find the rom that you just pushed, and flash it.

Okay, installing the SDK. And the command saying "rom.zip", the file that I have is like "rom.tar". Does it matter? I downloaded the rom from here https://developers.google.com/android/nexus/images

No the tar wont work through recovery. You should download a rom from here or here.
If you want to flash the stock rom through recovery you can download it here.

Nexus 10 stuck at Fastboot Mode....I think

I have a Samsung Google Nexus 10 (Wi-Fi) GT-P8110HAAPHE Which was running Android 4.4.3 (I think but it is definitely the latest version) and I simply wished to root it.
I started following a video on Youtube and now I am stuck at what I think is called the Fastboot mode where My options are to scroll through START/RECOVERY MODE/RESTART BOOTLOADER/POWER OFF. I was using the Wugs Nexus Root Toolkit v1.8.3.
No matter which I select it returns me to the screen with the START option. When I select POWER OFF it does indeed power off but when I switch it on again it returns to the fastboot mode START option. I can get into download mode if that helps.
I did create a backup but cannot restore it.
I have done some research and downloaded the Android SDK Suite and fastboot/ADB and drivers etc ready to try and recover but I don't know where to start.
I have a Samsung Galaxy S3 which I have rooted and installed a number of different ROMS on so I am familiar with rooting but not sure if I can use Odin or something similar.
I think I have included all the information I have and hope someon can assist.
Thanks.

This is why I tell people not to use toolkits. Since everything is automated, it's hard to tell what went wrong and where. When it comes to Nexus devices, toolkits are entirely unnecessary IMO. These Nexus devices are so super simple to flash manually it's ridiculous. /END RANT
Okay. Sorry about that. Now, back to the issue at hand. The menu you are describing is, in fact, the Bootloader (aka Fastboot mode). Prior to using the NRT, were you completely stock? Was your bootloader already unlocked? To me, it sounds like you may have wiped your OS. Have you tried flashing the 4.4.3 factory image?

I was completely stock. Whilst using NRT I believe I had just succeeded in unlocking the Bootloader and the video then stated that with 4.4.3 a Factory reset was required which is what I did but I did not realise that deleted the O2. I thought that was on a protected partition like my S3 phone.
I can't flash the factory image as I can't get into recovery or is there another way of doing it?
I suppose where tablets are concerned I'm a book but if you could point me to any instructions on how to flash manually I'm hoping I can recover my tablet. Thanks.

Dont know how you got your os erased. But im using a custom recovery since I got mine so maybe the stock recovery erses the os when doing a factory reset. A factory image cant be flashed via recovery and must be flashed via fastboot. Its really easy. But it will wipe the entire device. If you dont want to wipe everything you need to edit it..

I don't mind wiping the device but I cannot access Recovery Mode. When I select RECOVERY MODE and press the Power button to take me there it just returns me to the START screen.
I don't know if the fiollowing is relevent but it displays the word START vertically in the top left of the screen and next to it
Device Information
Product Name: manta
Variant: wifi
H/W Version: 8
Bottloader Version: MANTAMF01
Carrier Info: None
Serial Number: Don't think I should show that
Lock State: Unlocked
Reboot Mode Flag: None.
I have tried RESTART BOOTLOADER and that brings me back to the Start screen but still cannot access RECOVERY MODE.
Holding down the Power Button and Volume Up/Down brings me back to the Start screen again
I can get into DOWNLOAD MODE
Is there ANY way I can flash anything onto my Nexus 10 without using RECOVERY MODE like using Odin or Heimdall with a Samsung phone?

Great news everyone..........well for me that is :laugh:
Thanks to Androidbeat.com I now have a fully operational Nexus 10.
Just in case anyone else was following this I did it by downloading all the necessary files into on folder on my Windows Desktop, opening a Command Prompt from there and followed the instructions.
Thank you to those who offered advice here and although my Nexus 10 is showing itself to be unlocked I think I'll give a miss to rooting it and just suffer the limitations rather than risk bricking it again.

Glad everything worked out for you. Just an FYI for future reference, the stock recovery factory reset does not wipe the OS (at least it shouldn't). By default, AFAIK there are no custom recoveries that will wipe your OS either while doing a factory reset. It must've been something with the toolkit.
Regarding root, it's super easy to get root on this device. All you have to do is download the custom recovery image file of your choice. I prefer Philz, but you can use CWM or TWRP as well. Then, download the latest SuperSU zip file (I believe it's v1.99r4 now). Simply fastboot flash the recovery image, boot into recovery, and install the SuperSU zip, and you're good to go. The whole process takes two minutes, and no toolkit required.

[Q] stock rooted Lollipop OTA fails?

All,
Thanks in advance for any help you can provide. I have a Nexus 4 that I rooted and installed CWM recovery on, but I never installed any new kernels, ROMs, or radios. I'm currently on 4.4.4 and I want to upgrade to Lollipop. The OTA upgrade failed. So I tried returning to stock recovery and doing both the OTA and adb sideloading the OTA zip. Both fail.
The error message is "Package expects build fingerprint of google/occam/mako:4.4.4/KTU84P/1227136:user/release-keys or google/occam/mako:5.0/LRX21T/1576899:user/release-keys; this device has google/occam/mako:4.4/KRT160/907817:user/release-keys." (But I definitely have 4.4.4 on my phone, not 4.4.0.)
The extra difficulty is that I really, really do not want to wipe my phone. I have a lot of apps with a lot of configuration and other user data. So is there anything I can do? I guess I should try unrooting somehow? Or is there some other zip I can download that, through some type of recovery, will install the OTA without doing this check and also without wiping me?
Thanks again!

OTA wants complete stock and obviously it doesn't think so about your phone. One option could be to back up to the cloud or some place outside the phone with TiBu (or whatever backup app you trust), then flash lollipop and try restore from TiBu. Another option would be to unroot (Supersu has an option to completely unroot), then retry.

Actually, I figured out what works! This was on a stock rooted device with stock recovery, but I bet it would work with custom recovery too. Instructions modified from https://pay.reddit.com/r/nexus4/comments/1qny3f/howto_update_your_stock_w_lte_nexus_4_without/ .
1. Download the image you want from https://developers.google.com/android/nexus/images . Extract it, extract the .zip file inside it too, and collect all of the .img files into one folder.
2. adb reboot bootloader (and wait until the bootloader comes up)
3. fastboot flash bootloader bootloader-mako-makoz30f.img (or whatever file has a similar name, if you got a different image than I did)
4. fastboot reboot-bootloader (and wait until the bootloader comes back up)
5. fastboot flash radio radio-mako-m9615a-cefwmazm-2.0.1701.04.img (or whatever file has a similar name, if you got a different image than I did)
6. fastboot reboot-bootloader (and wait until the bootloader comes back up)
7. fastboot flash boot boot.img
8. fastboot flash recovery recovery.img
9. fastboot flash system system.img
10. fastboot format cache
11. fastboot reboot
12. Don't panic unless you've seen the startup animation for at least 15 minutes without anything else happening.
I lost root, but I imagine re-custom-recoverying and re-rooting won't be any harder than the first time around.

Hi moriarty00,
I'm going to try the same procedure, thank you for posting this.
Can you confirm that your data and app are safe after the upgrade?

Wow, a 12-step program
I simply rolled back my changes, and applying the OTA was as simple as pressing the "restart and install" button Here are some steps:
I used the app Flashify from Play Store to flash stock 4.4.4 recovery. I downloaded the stock factory image from google's own site (this one), used 7zip to extract the archives (tgz and tar), found "recovery.img" and transfered that to my phone. Then chose that file in Flashify.
Uninstalled all apps that made system changes, like Xposed framework and mods, BetterBatteryStats etc.
Removed Root with SuperSU cleanup function
Rebooted for good measure and apply OTA from notification - wait an hour or two for it to complete
Profit (do we still say that on the internet? Getting old here...)
I don't know if certain ways to get root will break the OTA. I used towel-root, and apparently SuperSU was able to undo that completely.

Unfortunately the steps did not work for me, maybe I had some irreversible modifications or I had followed a different rooting procedure.
Or maybe I made a mistake in the upgrading steps.
Anyway, I had to flash the whole ROM and now everything is working fine.

Hey!
Basically I have similar problem with upgrading from 4.4.4 to 5.0 using OTA. Log from TWRP says:
Package expects build fingerprint of google/occam/mako:4.4.4/KTU84P/1227136:user/release-keys or google/occam/mako:5.0/LRX21T/1576899:user/release-keys; this device has google/occam/mako:4.3/JWR66V/737497:user/release-keys.

Phone has been rooted using Nexus Root Toolkit. And as long as there wouldn't be a problem with flashing using adb and wiping all data, there is one setback... My nexus is somehow broken. Communication via USB does not work, at all. Neither phone nor PC sees other device. Certified LG service centre nearby said that it is problem with main board, so generally repair is unprofitable.
So question is: How do I update to 5.0 and then root, without USB connection to my PC?

Lolipop OTA capture

Update 2 after some fiddling I found that after flashing Pico Capps hdxposed is needed to make the play store work on this build http://forum.xda-developers.com/showthread.php?t=2618158
Update 1 New lolipop ota, this appears to be based on lolipop 5.1 and as such requires xposed unofficial by romracer if you want to use xposed Xposed for 5.0 would not flash for me. Same upgrade steps as before just this one instead of the bottom one and change your xposed package

Replace the original META-INF/com/google/android/updater-script with the one from the zip below. Remove "images" directory. This will ensure that your bootloader stays 4.5.3 and unlocked. When TWRP asks to add root, say yes.
If for some reason you lose TWRP (recovery), reflash it from within 5.0. Since you have root, no biggie. I'll play with this a bit too, but later.

I tried yours and tried my attempt. I'm getting a bootloop with both, let me know if you have any luck. TWRP protects itself from getting replaced.

OK. Does it flash successfully? Does it ask to install root? If it does and bootloops, the bootloader probably needs to be updated too. You could try to flash the new bootloader (just grab my uboot_4.5.3.zip, replace both files in /images, and re-zip).
The trick is that you install Lollipop, install root, and install the new bootloader separately. It should boot OK and you should have root in 5, but you'll lose TWRP (it won't be able to boot since the bootloader will probably be signed). To get TWRP back you'll need to downgrade to 4.5.3

Yes it flashes successfully and asks to install root. Looks like I'll be trying that tonight, thanks!
Edit we have a winner.
Flashed lolipop without bootloader

Fire has booted and is currently doing the very long lolipop upgrading screen

Currently booting to home screen but then back to the fire screen, etc. Probably my fault for not clearing the cache or a factory reset. I'm not at a computer at the moment but any ideas on how to fix this?

Turn it off with a long press of "power" button. Then press "power" and "vol+" together, this should get you into the Amazon recovery. It should offer you a factory reset option. Your system should be pretty much stock Lollipop, so I don't see why it should be doing what it does ...
Actually, does it now have stock Amazon recovery or TWRP ? My suspicion is that it should have flashed recovery during the first upgrade cycle.
Upon reflection, there is a chance you have a bit of a soft brick. If the factory reset option does not come up, it may end up a little tricky to fix things. I wonder if you'd be able to connect via adb before it reboots.

it appears to have TWRP but it will not boot to it with holding keys. I can get the device to appear in ADB but I can not authorize it. Appears to not actually be rebooting. just crashing to fire screen for some reason then back to launcher etc. I may be able to try again at home with a usb port that it remembers.

I wonder if Lollipop does not update recovery at all, and just uses the one from 4.5.4 You do have your old settings around, so there is a chance that prior USB authorization will help. It looks like one should have updated to stock recovery while in TWRP as the last step, after updating the bootloader, ir order to be able to do a factory reset in a situation like this.
If it comes to worst, Amazon reps never ask "did you brick the device yourself?". They only ask if you can get to the home screen, and if not, proceed with the replacement

I think TWRP just blocked it from updating. Oh well, if the ports at home don't work, I was eventually going to get it replaced anyway since I had a blue discoloration on my screen. Glad to be of some moderate use to the community instead of a leecher for once. May the next person have some luck!

ok I was able to get adb on a previously used port. I do not have root though. What are my options? What recovery should I flash? I also have a replacement kindle coming tomorrow so this is mostly for science now. I am also able to get into bootloader.
erased cache via fastboot. stuck on fire instead of boot to homescreen

So no adb anymore? I am not sure how SuperSu comes in, there gotta be su program somewhere.
Anyway, the great news is that JMZ is going to be back soon. That's going to boost our tinkering capabilities by 300%

Yes it flashes successfully and asks to install root. Looks like I'll be trying that tonight, thanks!
Edit we have a winner.
Flashed lolipop without bootloader
Installed su
Reboot to recovery
Installed superuser flashable zip
Flashed uboot file with lolipop images folder
Fire has booted and is currently doing the very long lolipop upgrading screen

And then soft brick ...
So I wonder now if one could do this :
install 5.2.0 via TWRP
install supersu.zip
and here it gets very tricky:
without any reboots, replace TEE1, UBOOT, and recovery to stock versions 5.2.0
The hope is to end up in 5.2.0 with root. If things fail, then booting into 5.2.0 recovery (which must be installed!!!) should give one an option to do 1) factory reset 2) downgrade to stock 4.5.3 as in here : http://forum.xda-developers.com/fire-hd/general/how-to-downgrade-to-4-5-3-root-device-t3139351
The problem is that I don't see a way to boot into 5.2.0, and then flash GAPPS after (since your TWRP was replaced by stock recovery earlier). So one would have to install GAPPS those via something like Titanium backup if root does work.
Please, if you already had 1 warranty replacement, don't do this. And, if you replace TEE1 and UBOOT (5.2.0) but not recovery, then you won't have any way to recover.

Yes I've used my warranty replacement so I'll be waiting until the official release before breaking my kindle again . How do you stop TWRP from preventing the recovery from being flashed? I noticed it gave a message about protecting itself.

Interesting, at what stage of the update did this happen? 5.2.0 file system is slightly packaged and is pain in the neck to peak into, but in 4.5.3 the recovery is updated via a pretty specific command install-recovery.sh , and I cannot find any references to this in updater-script. So I wonder at what stage will this be run. Also, there is no direct image for recovery, one has to reconstruct it as the commands below do. A bit messy ...
install-recovery.sh
Code:
#!/system/bin/sh
if ! applypatch -c EMMC:/dev/block/platform/mtk-msdc.0/by-name/recovery:5888256:6d9d1bbc4172c107db3228ed8d9f97111219c617; then
log -t recovery "Installing new recovery image"
applypatch -b /system/etc/recovery-resource.dat EMMC:/dev/block/platform/mtk-msdc.0/by-name/boot:5370112:c2c686ada1b194050a3c8f05e2102345df48e9ce EMMC:/dev/block/platform/mtk-msdc.0/by-name/recovery 6d9d1bbc4172c107db3228ed8d9f97111219c617 5888256 c2c686ada1b194050a3c8f05e2102345df48e9ce:/system/recovery-from-boot.p
else
log -t recovery "Recovery image already installed"
fi
Edit: It kind of looks like /system/etc/install-recovery.sh will be run at every boot. So I wonder if TWRP just renames it to something and calls it "protection". I guess one can double check the file system after 5.2.0 update while still in TWRP, and see what happened to recovery files.

Help
If someone can please help me. I downloaded the update to 5.0, unzipped it, replaced the updater script, but when I zip it back and try to flash it says that it failed. Am I doing something wrong.
Also, if someone has the zip file already and wouldn't mind uploading and sharing it, I would appreciate it.
Thanks for all the help.

Last time this procedure ended up with a soft brick. Are you sure you want to pursue this route?

Help
Maybe not, but if someone can help me with something else. The developer preview for the camera is extremely sharp and the 4.5.4 really isn't. Is there a way to make it crystal clear and sharp?

Meaning exactly what? It'd be possible to replace the camera app, one for another. Do you think some other system stuff is involved such as some sort of settings?
You'll have to find a way to mount the big 5.2.0 system update file as a filesystem, then you could read what's in there, including the camera stuff.

TWRP help
So I downloaded the zip file for 5.0 and it flashed and asked to install super user. I had to download the apk for supersu and then update it.
But the problem is that I lost my twrp. I push the volume + and power and it just reboots. I also lost my play store. Any thoughts how to get twrp back on?

Nexus 6p Root Failure / Boot Loop / Android 6.0.1

I tried to root my Nexus 6P and now I'm stuck. It won't finish booting. I followed instructions found on the web. I unlocked bootloader with no problem. I copied the latest SuperSU file to the phone. I installed TWRP recovery. However, I could not find the SuperSU file when using TWRP. Nevertheless, when I went to exit, TWRP asked if I wanted to instal SuperSU. I recall reading somewhere that it will install the wrong version of SuperSU (not the one for 6.0.1). Somehow I must have hit the wrong selection because it installed it anyway. Now I have an infinite loop.
I have tried to factory reset with TWRP. That fails. I downloaded the 6.0.1 images files from Google. I tried to run flash-all.bat, but that doesn't work. I have pushed images and ZIPs to the /sdcard/ folder with ADB. ADB recognizes the device, but fastboot does not (when connected to my laptop) (which is why flash-all doesn't work). I have tried to install the images/zips with TWRP. However, I always get "failed" messages. I get messages that partitions won't load.
Stupidly, I do not have a nandroid backup (yes, I know, a dumb move).
Any suggestions on what to try next? I'm at my wit's end with this. I've searched the web all morning and found all kinds of helpful info, but I can't find anything to get me past this point. I am perfectly willing to wipe it all out and start over again if I could just force it to do that. I just bought it so I suppose I could return it (I think there's a 30-day return policy), but Google might not like it if it comes back in this state, I suppose. I had an AT&T Galaxy Note 5 for half a day but found out, after the fact, that I can't root it.
Thanks for any help or suggestions.

Why did you follow instructions found on "Web" when u have the beautiful guide by our @Heisenberg? Read this thread. Instead of running flash - all. Bat file, follow the instructions in this guide. http://forum.xda-developers.com/showthread.php?t=3206928

I saw that post. I wish I had followed it. However, the instructions are very similar to what I tried, although not exact. Where I went wrong is letting TWRP install SuperSU for me. I didn't mean to but when I touched the phone it installed it (of course, I hit something, but I don't know what). Fastboot does not recognize the phone in recovery. I can follow Heisenberg's instructions to get back to stock IF fastboot would recognize the phone. ADB recognizes the phone. Would it be possible to use ADB Sideload instead? How can I force fastboot to recognize the phone? If I could do that, I would be able to flash images back to the phone. Thanks!

U should try fastboot in bootloader / download mode instead of recovery mode..

OK, two comments: Duh (as I slap my head) and Bless You! That worked. I'm back to stock. At least the phone works now. I'll try again to root following Heinsenberg's instructions! Thanks. Where do I sent the beer money?

Well, I'm back to a stock phone, anyway. Flashing SuperSU per Heinsenberg's instructions did not give me root. Oh well. I'll keep trying. It did install and it did reboot just fine. However, root checker says I have no root and Titanium Backup won't run, either. Thanks.
