Boot loop problem

Hello,
I tried installing a custom ROM on my 7310 and it had issues. I have tried installing the original ICS from the sammyfirmware site using ODIN. Now I have a boot loop. I think I need to repartition, but when I click the repartition checkbox in ODIN I get an error.
Do I need to repartition? If so, how do I do it? If not, how do I fix this error?
Thanks.

A few questions:

What did you try to flash and how did you try doing it (CWM, ODIN, ...)?
What 'issues'?

How far into the boot sequence does it get?
Are you able to get into recovery?
If so, what recovery do you have (Stock vs CWM)?
Have you tried seeing what is causing the boot-loop using adb?

This is an action of last resort. Exhaust all other avenues first.

I used CWM to flash AOSP 4.1.2. It seemed to work fine for a day or two, but then it needed charging (as normal). I let it charge over night and in the morning it had less battery. I figured the charger or cable were flaky so I tried another set on another outlet and same thing. Then it finally ran out of battery. I let it charge again over night and when I tried to turn it on it was really slow. The boot animation was only 1 frame every couple seconds. It would eventually boot all the way up, but it was still REALLY slow. So I went into CWM and reflashed the same ROM. Then I got a boot loop of the boot animation. I couldn't get into CWM any more, so then I went into download mode and flashed the official firmware and flashed it with ODIN.

Now when I turn it on it just says, "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again."
I can flash again with ODIN and it will get to the Samsung boot animation and just pulse SAMSUNG.

If I hold power and volume down I can get into download mode or Samsung recovery, not CWM, and power with volume up doesn't do anything.

I don't know anything about adb and I'm not sure what I would be looking for. Is there a tutorial I can follow somewhere?
Thanks for any help!

This worked for me with similar problem
Hi Spazlon,
Sorry I'm not allowed to post links yet as I am also very fresh. But I've underlined the addresses so you should be able to find them
I just spent the best of 2 days trying to solve a similar issue - my 8.9 P7300 kept running in boot loop. It had been running ICS stable for several weeks, then suddenly started to loop boot for no good reason. Anyway - you need two programs installed on your computer as well as USB drivers for your tablet. The two programs are Odin and SDK developer package. Odin3 v 1,87 and 1.85 are found here: filecrop.com/Odin-1.87 - try some of the links, one of them should work without having to type a password. The SDK is found here: developer.android.com/sdk You can find more about how to use the developer package on that site as well, but I installed as support for Android 2.1 through to 4.1
Also install the USB driver files for your tablet on your PC. For example from here: xpdrivers.com/usb/_1_24.cfm?gclid=CL2iDs7MCFWF7cAodxFYANQ
You also need the following recovery files which you can find by searching the developer forum for galaxy tab 8.9:
ClockworkMod_Recovery_v5.5.0.4.tar
P73xx_Stock_Recovery.tar
Clockwork_Recovery_6.0.0.8_GT-P7300.zip
and finally a ROM of your choice, for example the ICS rom cm-9-20121028-NIGHTLY-p5.zip that I just used. You can find the latest official ICS ROM's here get.cm/?device=p5
Now - hold down the volume down button on one of the boot cycles. You should now get into a menu with two choices - Download and Recovery. Default is "Download" - if you press volume down you switch between the two choices. Press volume up to select the choice you want.
First you want to select the "Download" option. Then connect your tablet to your PC. The drivers should now install and your tablet should read that you are connected.
Now start Odin3. Click the PDA button and select your P73xx_Stock_Recovery.tar file. Then press Start.
Once finished the tablet will reboot, and you now need to once again get into the recovery menu. Now select the recovery option, not the download menu. You get into the stock recovery menu where you navigate with the volume buttons and select choices with the power button. Do a full factory reset and wipe the cache. WARNING - you will loose ALL your data, but it'either that or stick to a bricked tablet so.... You will also loose your root access,m which is why the next step is needed.
Now that everything is wiped clean you can use Odin again in "download mode" to install ClockworkMod_Recovery_v5.5.0.4.tar with the same procedure as before. You now have root access.
Reboot again and once again into the recovery mode (not download mode). Once you get into the CWM recovery menu you are ready for the final step, which is to install your new operating system.
Go to your SDK installation folder and find the folder named "platform-tools".
First you want to copy two files into this folder (provided you want to install Cynaogen Mod 9):
Clockwork_Recovery_6.0.0.8_GT-P7300.zip
and
Your ROM file of choice
Press shift and right-click in that folder and select "Open command window here". In the command prompt write
adb shell
Note - I had some problems here which was caused by lack of permissions. On your tablet in the CWM menu there should be a choice under the advanced menu for fixing permissions. Use that and you should be able to get into the terminal shell afterwards with the adb shell command
Now write the following command sequence:
• mount /data (don't worry if you get an error message - it means the folder is already mounted)
• cd /data
• mkdir media (if you get an error message saying the folder already exists, that's also OK!)
• exit
• adb push Clockwork_Recovery_6.0.0.8_GT-P7300.zip /data/media
Now you may have to wait a little while until your command prompt is back confirming that the file was uploaded.
Now on your tablet go to the menu point "install zip from sdcard" and find your CWM file that you just uploaded and run that.
Reboot once again into the "recovery mode" - we are now nearly finished.
Run the above push command again from the computer terminal window, this time to upload the ROM file you want to install. (the command is adb push [filename].zip /data/media)
Now on your CWM recovery menu once again run the zip file you just uploaded from the "install zip from sdcard" menu
When completed and you now reboot you should have a completely fresh android installation. Hope this helps.
Remember to mark this thread with solved if it works!
Thanks to kallt_kaffe and all the others who helped me through their various posts (hope that coffee isn't getting too cold again), as well as the following web sites that indirectly helped me resolve this issue googleymind.com/2011/11/guide-so-you-think-you-bricked-your.html#.UJUNN8XAd8G and galaxytabhacks.com/galaxy-tab-10-1-hacks/how-to-root-galaxy-tab-10-1-the-easy-way/
Good luck.

Thanks! I'll give this a try when I get home. I'll let you know how it works out.

Don't ever try to 'repartion unless you really know what you're doing. You're soft bricked. Repartion and you'll hard brick.
I'd go back and get hc from sammobile and flash that with Odin. Ics has had some problems.

Agreed - my procedure avoids manual repartitioning - I tried lots of other procedures but none worked. I think my data partition had become corrupt because I kept getting error messages. My first try was to recover with my cwm recovery file I made originally but I kept getting back to the boot loop .

I followed the steps outlined by mobjunky and was able to get an official Honeycomb ROM installed, boot the official and copy my custom ROM and CWM 6.0.0.8 on it. Then install CWM 5.4.0.4 followed by 6.0.0.8.
Now my problem is that any custom ROM I put on there just does a boot screen loop. I tried CM10 and the latest AOSP. To install the ROMs I just booted into CWM, installed the ROM from zip, then installed the gapps. I've tried with and without formatting the cache, user data, and Dalkiv, same results.
What am I doing wrong? I have loaded tons of ROMs on this before without any issues, then all of a sudden I can't get anything except official loaded.

did a format /system before installing the custom roms? This is an important step.

This fixed it. Never had to do it with any of my other devices. CM10 loaded quickly after that. Loving how fast JB is!

How to Install 4.2 images, keep root and all data

**Disclaimer** If you don't understand what follows, don't attempt this. I'm not responsible for you softbricking your device,
This is a quick guide for how to install the new android without losing anything. You'll need fastboot for this. Also, before doing this, be sure to download the supersu cwm update zip, and have it on your sdcard. Make sure you also already have a custom recovery installed (I did twrp, but i'm sure cwm will work just as well). I would also suggest having a backup done, through titanium backup and through recovery, just incase.
First, download the factory images for the n7 from google's website. Decompress them (if you're in windows, you'll need winrar or something similar.) After you decompress the archive, there'll be another one inside (image-nakasi-jop40c.zip), decompress this one as well. Under here, you'll see the .img files for all the partitions. For now, go up one directory. You'll also see here bootloader-grouper-4.13.img. Once you have all this, reboot into the bootloader.
Once you're in the bootloader, you can update the bootloader to the new version (this step isn't needed, but I did it anyways). Plug into your pc, and type fastboot devices. Make sure it's not blank. If it is, you have to update drivers. If you can see the device, open up a command prompt, and cd to the directory that has the bootloader-grouper file. Type the following:
fastboot flash bootloader-grouper-4.13.img
then, after it's done, type:
fastboot reboot-bootloader
Now, you'll be booted back into the bootloader, it'll say 4.13. On to the rom.
cd into the folder image-nakasi-jop40c (make sure you see the files system.img and boot.img before you continue. If you don't see them, the next steps will do nothing but erase your kernel and system parition.)
now, you see the image files. Type the following (still in the bootloader)
fastboot erase system
fastboot flash system system.img
wait until it completes, then type:
fastboot erase boot
fastboot flash boot boot.img
Once this is done, hit the volume up on the device until it shows recovery mode on the top. When it does, push the power key and you'll boot into your recovery (shouldn't be touched.) Inside here, flash the supersu cwm zip file, which'll flash the superuser binary, and supersu. Once this is done, do a factory reset (removing your data and cache.) Boot into the rom.
Once it's booted, you'll notice your internal sd card appears to be empty (mine did, I was worried at first.) For some odd reason, it moved the entire contents of my sdcard into a folder on it called 0. When you get back into android, simply move the folder all up one level so they're in the proper place. You now have the rom booted, rooted, with all your data. Now, you can do a titanium restore to get all your stuff back.
My first boot got stuck for some reason. if it happens to you, just hold the power button and hard reboot. (I did this on 2 devices, it only happened to one of them, so I figured I'd give you all warning.)

SuperSu binary: https://docs.google.com/open?id=0B7a8xHNJlpgTR0ZkR1pWZWR2VzA

Thanks for this.
I flashed the 4.2 ota in the dev section and I lost root. Can I just flash the supersu binary in cwm to regain root?

Thanks for this.. Apparently you found out too a clean 4.2 isn't rootable via typical methods.
That SuperSU package did the trick. I have to remember to keep a SuperSU binary on hand for these kinds of situations that SuperUser fails..

Yes. If you do it though cwm, you're not using any exploits, you're just inserting the superuser binary and supersu.apk into the proper places on the rom. On any nexus device, any rom, this will root it.

DANGER WILL ROBINSON!!
The "odd reason" is called "multiple users" - add a second user and they get a folder called 10.

Exactly.
If everything goes right we should have an AOSP prerooted build in about *looks at watch* 20 minutes.... Unless there is a compile error or SU error. *laff*
Back to watching the scrolling terminal window

Just got this working on a mac...
did not update bootloader(couldnt get it to)
other than that, same commands except all fastboots are ./fastboot on a mac
the only other trick is i needed the fastboot and abd files in the jop40c folder...seems to have worked like a charm....im deff on 4.2 with su installed... and it looks like my data is still there...once google is done restoring i'll know just how sucessfull it is, but so far, seems to work!!!

I did this all on linux, just kind of adapted the guide for windows. I figured all the linux users would understand how to do it on their own. Glad to know it's the same for mac as well.

OK where did they put the developer options? Not in settings on my 32GB 4.2 device
Never mind. This: http://www.androidpolice.com/2012/1...hidden-in-android-4-2-heres-how-to-find-them/

Settings - about tablet - build number
push it a few times and it will enable dev options

You have .bat file in the package.

Why so complicated?
I downloaded 4.2 from here:
http://android.clients.google.com/p...gned-nakasi-JOP40C-from-JZO54K.094f6629.zipia
I then just flashed it from recovery via CWM.
Done.
CWM asked me if I wanted to maintain root and of course I chose the correct answer on this, so now my N7 is running on a rooted 4.2.

Here is my method:
1. Download official 4.1.2 from http://forum.xda-developers.com/showthread.php?t=1929270 and 4.2 OTA image from http://forum.xda-developers.com/showthread.php?t=1989188
2. Boot into CWM (i have CWM touch installed)
3. Clear data and install 4.1.2, don't forget to turn on root in the installer
4. reboot check that root is fully working
5. reboot into recovery install 4.2
6. before reboot CWM will ask to disable recovery flash and protect root. Ansver yes to both questions

I'm confused, it says if you are already on a custom rom, just flash as usual.
What makes this different?

I was on stock ROM rooted with some system modifications, and this wwadd the only way I could get the update working...

For some odd reason, it moved the entire contents of my sdcard into a folder on it called 0. When you get back into android, simply move the folder all up one level so they're in the proper place. You now have the rom booted, rooted, with all your data. Now, you can do a titanium restore to get all your stuff back.

So I'm at the step listed above. I have 4.2 on my device but I can't seem to find this "0" folder. I'm browsing the /sdcard folder via adb shell. Am I looking at the wrong place? Do I have have the incorrect permissions? Or might it not be there?
Thanks.

Ill have to wait until a rooted rom is created, I have no comp.

Not advisable to move this folder - if it got moved to a new location by the o/s then there's probably a good reason why - maybe like 4.2 introducing multiple users
Each user appears to get their own "home" directory created in /mnt/shell/emulated/
Default user dir is "0"
Second user dir is "10"
Each contain the standard dir's from 4.1 and earlier.

Why so complicated?
I downloaded 4.2 from here:
http://android.clients.google.com/p...signed-nakasi-JOP40C-from-JZO54K.094f6629.zip
I then just flashed it from recovery via CWM.
Done.
CWM asked me if I wanted to maintain root and of course I chose the correct answer on this, so now my N7 is running on a rooted 4.2.

You had two extra characters at the end of your link, but I fixed it above and it's good to go for others in the future. Just flashed it in TWRP, it didn't ask if I wanted to maintain root, hit reboot when it was complete and lost root, so it doesn't work for everyone - good news is that all my data remained intact without having to resort to advanced restoring my data from a backup....
When I tried the SuperSU binary root flash trick, I finally got root back. But don't think it's as easy to get to recovery! I had to obtain the TWRP Recovery one more time since it wiped it and put in place a recovery that did absolutely nothing but reboot the device after a few minutes, so you'll have to
Code:
fastboot flash recovery openrecovery-twrp-2.3.1.1-grouper.img
to get TWRP back.... Hope that helped everyone!

}
Setup, Preparation and Prerequisites
Basic tasks that I may refer to throughout this guide:
Open command prompt - Press Window Key + R, type in "cmd" (without the quotes), and hit enter.
Enter the bootloader - Turn the phone off. Hold volume down + power. The bootloader is also known as fastboot mode.
ADB and Fastboot Installation
Download the full Android SDK here (scroll to the bottom of the page>DOWNLOAD FOR OTHER PLATFORMS>SDK Tools Only) or get a slimmed version containing only the essential components(Thanks @El Daddy)
Link removed since it expired
Extract the zip and place the android-sdk-windows folder on your desktop.
**If you chose to download the slimmed sdk skip to step 5**
Only if you downloaded the full sdk: Go into the android-sdk-windows folder and run SDK Manager.exe. Install the following packages (there are a total of 4 packages):
- Tools > Android SDK Tools, Android SDK Platform-tools
- Extras > Android Support Library, Google USB Driver
Only if you downloaded the full sdk: Go back into the android-sdk-windows directory, and you should see a new folder named platform-tools. If you don't see this new folder, repeat the step above.
To confirm that it is indeed working, open a command prompt window and enter the following commands:
Code:
cd Desktop/android-sdk-windows/platform-tools
adb version
If it displays "Android Debug Bridge version x.x.xx" it is working. If it is gives an error saying that adb is not a recognized command, it has not been successful. Carefully repeat the steps above if this is the case. Close the command prompt window when you are done.
USB Debugging - On your phone go to Settings > About phone > Tap on Build number 7 times. This will enable Developer options. Now go back to Settings > Developer options > Enable USB debugging
Show File Extensions - Open a command prompt window and run "Control folders" (without the quotes). Go to the View tab and uncheck the "Hide extensions for known file types" option. This will help avoid confusion when renaming files.
Battery - Ensure that your phone has at least 60% battery remaining, and that your PC is plugged in and wont shut down spontaneously during the process. The procedure doesn't take very long (5-15 minutes), but its best to have enough charge in case something goes wrong.
Backup (Optional) - Unlocking the bootloader will completely wipe all data from the device. This includes apps, settings and even the contents of the internal sdcard (pictures, music, etc.). Copy all important files off the phone onto a PC or upload them to a cloud.
Driver Installation - Try this first, but if that doesn't work look here. Still having issues? Give this a try. None of these working? Hopefully this does the trick.
Downloads
Download a custom recovery of your choice and the SuperSU zip below. Place both files (recovery image and root zip) in the platform-tools folder located on your desktop within the android-sdk-windows folder.
Custom Recovery:
TeamWin Recovery Project (TWRP) or ClockworkMod (CWM)
Root:
SuperSU
Information
Rooting a nexus device is actually quite a simple and easy process. Before you begin, it is recommended that you at least try to understand what each part of the process will do. Although this guide will elongate each step in order to show all of the details, the method used can be broken up into 3 main steps: Unlocking the Bootloader, Installing a Custom Recovery and finally Rooting. Each new step relies on the previous step to have been completed, and a basic summary of each part is:
Unlocking Bootloader: Opens the door to the internal memory of the device to be written on to. This allows you to flash images onto the main partitions of the phone.
Installing a Custom Recovery: A custom recovery is flashed onto the recovery partition of the device and overwrites the stock recovery that exists by default. Custom recoveries bring lots of functionality and give you the ability to perform wipes, install flashable zips, create full backups of your NAND (Nandroid backup), and various other features. An unlocked bootloader is needed to install a custom recovery.
Rooting: You can gain root by either flashing via recovery a pre rooted custom rom, or flashing a zip containing the SuperSU binaries. A custom recovery is necessary to do this.
After completing these steps your phone will be rooted, the phone will have a custom recovery installed, and the phones bootloader will be unlocked. This, in my opinion, is the most practical and beneficial method for rooting your phone. It gives you some basic adb/fastboot knowledge, and should hopefully help you have a decent understanding of what is going on. Also this method will work regardless of what android version your phone has. Using a toolkit will only make things worse in the long run...learn to do it properly. It has been proven that every time you use a toolkit, god kills a kitten. Save the kittens.
If you are confused by anything in this guide, I would highly suggest getting it clarified being before moving on. Ask your question in this thread and I or someone else will likely answer. Also I'd suggest that you read over the whole thread a few times before actually doing anything to the phone.
Understand? Good...lets begin:
1. Unlocking Bootloader
Turn the phone off. Then boot it into the bootloader/fastboot mode by holding volume down + power.
Plug the phone into your PC, then open a command prompt window window and type:
Code:
cd Desktop/android-sdk-windows/platform-tools
Code:
fastboot devices
This command will list the connected devices. If your phones serial number shows up you are good to go and may continue. If the phone is NOT listed this indicates that your drivers are not installed correctly. In order for you to continue you must fix your drivers so that your phone is listed under fastboot devices.
If the phone has been recognized by the command above, proceed to unlocking the bootloader with the following command:
Remember that this step will wipe EVERYTHING off the phone
Code:
fastboot oem unlock
On the phone a screen should pop up asking whether or not you would like to unlock the bootloader. Use the volume rockers to highlight "Yes" then press power to confirm the action.
After the above command has finished excuting, run the following (DO NOT skip this step, it is more important than you think):
Code:
fastboot reboot
The phone will reboot. Next you will be presented with a screen containing an android logo and a progress bar (this may take up to ten minutes to complete). Wait until the phone has fully booted up into android, then proceed onto the next section of the guide.
Close the command prompt window.
2. Installing a Custom Recovery
Turn the phone off. Then boot it into the bootloader/fastboot mode by holding volume down + power.
Rename the recovery file that you downloaded above to recovery.img. *Make sure that you rename it to recovery.img NOT recovery.img.img* Remember that you should place the file in the platform-tools folder inside of the android-sdk-windows folder on your desktop.
Open command prompt and run the following commands:
Code:
cd Desktop/android-sdk-windows/platform-tools
Code:
fastboot flash recovery recovery.img
On the phone, use the volume buttons to scroll onto "Restart Bootloader" and hit power to select it. After the bootloader reloads, use the volume buttons to scroll onto "Recovery Mode" and power to select it. You should then be greeted with your newly installed custom recovery.
Close the command prompt window.
3. Rooting
Now that your phone has an unlocked bootloader and a custom recovery installed you have a two options to gain root (Pick one or the other. You don't need to do both)
Option A) Flash SuperSU binaries which will give you root with the stock rom
Confirm that you have downloaded the SuperSU zip from the downloads section above and that it is located in the platform-tools folder inside of the android-sdk-windows folder on your desktop.
Turn the phone off then boot into the bootloader. (volume down + power). Once in the bootloader use the volume rockers to scroll onto Recovery Mode, then press power to select it. This should bring you into your newly installed custom recovery. Leave the phone at the home page of the custom recovery.
Open a command prompt window and run the following commands:
Code:
cd Desktop/android-sdk-windows/platform-tools
Code:
adb push UPDATE-SuperSU-v[COLOR="Red"]X[/COLOR].[COLOR="red"]XX[/COLOR].zip /sdcard/
This will copy the SuperSU zip onto your phone. Once the command has completed continue.
Instructions for TeamWin Recovery Project (TWRP):
Install > browse to SuperSU zip and select the it
Swipe to confirm the installation. Then reboot.
Instructions for ClockworkMod (CWM):
install zip from sdcard > choose zip from sdcard.
Next, browse to the location where you previously copied the SuperSU zip and select the it.
To confirm the installation, scroll down to "Yes" and select it. The installation shouldn't take very long, and once it has completed you may reboot.
Option B) Flash a custom rom which will come pre-rooted
Note that not all custom roms will be pre rooted, however the majority of them are. Read the OP of the ROM thread to see what the verdict is.
Copy a custom rom (you can find these in the Nexus 5 Android Development and Nexus 5 Original Android Development section) onto the phone (remember the location where you copy it to)
Turn the phone off then boot into the bootloader. (volume down + power). Once in the bootloader use the volume rockers to scroll onto Recovery Mode, then press power to select it. This should bring you into your newly installed custom recovery. To install a custom rom the general procedure to follow is: factory reset, wipe cache + dalvik cache, flash ROM, flash GApps. Here are the recovery specific instructions:
Instructions for TeamWin Recovery Project (TWRP):
Wipe > Swipe to Factory Reset
Install > browse to the location where you previously copied the ROM zip and select it > Swipe to confirm the installation
Install GApps using same process as ROM, then reboot.
Instructions for ClockworkMod (CWM):
wipe data/factory reset
wipe cache partition
advanced > wipe dalvik cache
install zip from sdcard > choose zip from sdcard > navigate to the location of the rom > select the rom > confirm the installation by selecting "Yes"
After that you may install the GApps using the same method for flashing the rom, and finally reboot the phone.
Keep in mind that the first boot after installing a custom rom & wiping the phone may take longer than usual, as the phone will need to rebuild the dalvik cache and initialize other first boot stuff.
Congrats! That is all! Your phone now has an unlocked bootloader, a custom recovery installed and is rooted...Plus you saved a kitten. Enjoy

Troubleshooting & FAQ
Why am I seeing a red triangle with a dead android when booting into recovery even after I flashed a custom recovery?
What you are seeing is the stock recovery, meaning that the custom recovery that you flashed did not install correctly. Try the following suggestions:
Make sure you are using the USB cable that came with your phone. Only use other ones, if the stock one isn't working
Try using different USB ports. USB 2.0 ports (the ones that ARE NOT blue) are preferable. USB 3.0 ports (the blue ones) may cause problems with connectivity.
If you are on a desktop, use the ports on the back of the tower instead of the ones in the front. These ports are directly connected to the motherboard, rather than the ones in the front which are usually attached to a header cable which then indirectly connects to the motherboard.
My phone wont boot into android. I can only access the bootloader and custom recovery. What do I do?
Suggestion 1: Factory reset via recovery.
TWRP Instructions:
Boot into recovery
Wipe > Swipe to Factory Reset
Reboot
CWM Instructions:
Boot into recovery
wipe data/factory reset
wipe cache partition
advanced > wipe dalvik cache
Reboot
If that doesn't work continue onto Suggestion 2.
Suggestion 2: Push a ROM to your phone and flash it.
Download a ROM onto your computer. If you don't have time to look for a ROM, just download the stock ROM.
Move the downloaded ROM onto your desktop, and rename the file to "ROM.zip" (without the quotation marks)
Boot phone into recovery
Open command prompt and run the following commands:
Code:
cd Desktop
adb push ROM.zip /sdcard/
Wait for it to finish copying the file, then flash the ROM. If you need further details on how to flash a ROM take a look at the OP, section 3. Rooting, Option B)
If that doesn't work continue onto Suggestion 3.
Suggestion 3: Flash the factory images.
Flash the factory images
My phone wont boot into android. I can only access the bootloader. What do I do?
Flash the factory images
My phone exploded. What do I do?
Tape it back together then flash the factory images

Yes, if you only unlock the bootloader you will still be able to get ota's. The lock state of your bootloader will not affect your ability to receive ota's.

What about if you unlock the boot loader and root, will you be able to get OTAs then? I guess a better question is what's the point of no return (without reflashing the factory image) where you break OTA updates? Thanks for the thread btw!

Can people please post confirmation of TWRP or CWM recoveries + rooting working without problems if they've done it? I know it's unofficially supported at this time, but getting some data collected would be useful.

If you unlock bootloader & root, and modify some system files, OTAs may not be able to pass some pre-install checks, at least this has happened to me on N4 before. I added one line to /etc/build.prop, also one of the older SuperSU versions had to be uninstalled for pre-install OTA checks to pass.

There isn't *yet* a booting custom recovery for the Nexus 5. Give it a couple of days.

Did u order one chromium?

Is unlocking the bootloader going to be the same as on my GNex, where it wipes the device in the process? If so, this will be the first thing I do when I get it out of the box on Monday.

If you wipe cache exactly after you unlock the bootloader, without booting, no.

There are currently no working custom recoveries, so it really only makes sense to unlock the bootloader for now. That way you'll be ready to continue on with the guide right when a stable recovery is released.

Ok, the wording in OP is:
"Currently neither recovery has official support for the Nexus 5, so the download links below are unofficial and may not be functioning 100% correctly."
and:
"**Warning: Currently there are no officially stable custom recoveries, so i would only recommend unlocking the bootloader for now**"
Which implied that it does work, just not thoroughly tested. Now from the recent replies you're saying it DOES NOT boot at all into recovery?

Yes that is correct, they do not boot. I will update the OP now, sorry for the confusion.

[Guide] How to recover Soft-Brick from OTA & custom recovery

I know this one has been answered a few times in pieces, and somewhat understandable manner. However, I wanted to decrypt this for everyone to be able to understand how to do it and to overcome this particular issue.
Issue: You have a custom recovery installed and your LG G2 prompts you to install the new OTA (i.e. KitKat update). You then accidentally/unknowing of consequences accept the update. Your phone restarts and keeps going to the custom recovery which you had installed, instead of booting to the update. You endlessly try to boot to your phone, but it just keeps going back to your custom recovery.
Things to do ahead:
1. Have LG G2 drivers installed on computer you will be using. You can get those from the LG website easily by searching LG G2.
2. Obtain ADB and fastboot files from HERE
3. Obtain working TWRP vs 2.7.0 from HERE if you don't have the TWRP recovery installed (i.e. if you're using CWM or Philz recovery).
Recovery Procedure:
1. If you have TWRP recovery installed, proceed from step 9
2. If you have CWM or Philz recovery installed, follow these next steps.
3. When inside CWM/Philz recovery, click on option to install zip.
4. Have your phone connected to a computer which has the LG G2 drivers installed, found on LG's site. Make sure to install drivers without phone connected to computer first. After installing, restart computer, and then plug phone to computer USB port.
5. Now that you have the phone plugged to comp, and that the comp has recognized your phone, open up CMD and navigate to the folder where you have your ADB file located and workable TWRP recovery zip file.
6. Once there, click on install using sideload on your phone's custom recovery which should be located inside the install zip option.
7. Then type in CMD on computer this: ADB sideload TWRP-file-name.zip
Note. Replace TWRP-file-name.zip with whatever the TWRP zip file on your computer is named to the letter.
8. Your phone will install TWRP recovery at this point. Once it finishes, restart your phone by rebooting recovery (should be an option somewhere there in the main level of the recovery)
9. TWRP should boot now. Once inside TWRP, click on Advance
10. Then click on Terminal Command
11. Next click on Select
Note: Do not navigate to any other folder. Just click on Select. You'll know what I mean once your in Terminal Command.
11. Type this command in the space provided in your phone (NOT in CMD) which should be now in Terminal Command mode exactly to the last letter. I'm not kidding; don't miss a character or replace a number. You risk nuking your phone. Double check your typing.
Type this: dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
Note: You should note that there is a space between dd and if=/dev, and another space between /zero and of=/dev
12. Once the command finishes running, about 30 seconds or less, restart phone. And voila. Your phone should boot back to your pre-selecting update with OTA mode.
In my case, I wiped everything and tried restoring one of my nandroids. That did not help me boot my phone. However, when I did the above mentioned steps, my phone booted to my backed up state which I installed prior.
Hopefully you don't end up being a victim of this. But if you are, now you can confidently bring yourself back :good:
Good luck and share your progress. Thanks!
Cheers,

I repeated this three times, and no luck... any suggestions?

I did it a tad differently. I am running Windows 7.
First I downloaded these universal drivers so my phone was recognized under Device Manager, went to my adb directory with command prompt and typed the following:
adb shell
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
I just preferred using the keyboard, but your directions will work, too.

Soft bricked phone? Can't install recovery and can't install a rom

Okay so I got my oneplus 3t today and I updated it to Nougat via the ota file all good so far. I then decided that I wanted to install a custom rom so I downloaded twrp supersu etc everything needed to root and install the rom. Here's where it went wrong in knowingly I downloaded the wrong twrp flashed it and it would just hang at the flash screen for twrp. Anyway after hours of trying to install a recovery I managed to get a stock one to semi work, now it turns out I don't know how I did it but my phone won't even boot it just turns on and goes straight to fastboot mode. I managed to get a stock recovery semi working but it won't let me install the stock rom from internal storage and I've tried updating through adb and it will hang at a random percentage for a good 20 mins and then just fail. Really need some help here it would be great, thanks

Hi,
If you can get into fastboot mode then the best recourse is through there. Hope you properly OEM unlocked your device.
First of all, you MUST have the latest adb/fastboot binaries and FOR SURE have the correct drivers.
Follow the links on this XDA article to download the latest adb and fastboot binaries: https://www.xda-developers.com/google-releases-separate-adb-and-fastboot-binary-downloads
This is the link for the Windows binary: https://dl.google.com/android/repository/platform-tools-latest-windows.zip
Extract all the contents of the zip file in a folder on your PC.
Then, also make sure to have THE CORRECT twrp, 3.0.2.0 or 3.0.3.0. This is the link but currently it is down: https://twrp.me/devices/oneplus3t.html
Download THE IMAGE, NOT FLASHABLE ZIP and put it in the same folder as the android platform tools above.
Finally, download the latest complete 3T firmware from OnePlus from this link: http://downloads.oneplus.net/devices/oneplus-3t/
I STRONGLY recommend not to use an update zip, even a full ROM update zip as that one might not include certain firmware images.
Put THE ZIP on the same folder as the others, DO NOT EXTRACT ANYTHING.
On your PC, open a command prompt in the folder where you extracted the android platform tools and run the following: fastboot boot twrp-3.0.3-0-oneplus3t.img (assuming you downloaded the 3.0.3 version of twrp).
Your phone will TEMPORARILY accept the twrp recovery as a boot image and boot from there. NOTHING IS BEING PERMANENTLY WRITTEN AT THIS TIME.
After that, enter TWRP's Wipe menu and wipe system, data and cache.
Finally, use TWRP's Advanced menu and enter adb sideload mode. Once there slide that slider to the right to enable adb mode and return to your PC and enter the following command in the command prompt:
adb sideload OnePlus3TOxygen_28_OTA_029_all_1612131737_17e7161d2b234949.zip (assuming you downloaded the 3.5.4 binary from OnePlus).
TWRP should properly flash the OnePlus ROM and hopefully, return you to proper function. You can then update back to Nougat.
Hope that helped!

Yeah that sorted it thanks a lot

Use the emergency tool for OP3T and start from scratch:

I'm trying to follow this guide, but did you miss something out here?

Once I do "fastboot boot twrp" and get a success, then what?
Do I need to somehow reboot the phone into TWRP - because that didn't happen on its own.
If so, how do I do this?
Thanks,

My instructions while detailed are not step-by-step. I expect the person reading them to have their PC configured correctly and at least a vague idea of what they're doing.
So, assuming you put the correct TWRP image (my command uses the name of the image for TWRP 3.0.3.0, you MUST alter it to reflect the actual image's filename if it's not that) on the same folder as the fastboot binary then yeah, the command
fastboot boot twrp-3.0.3-0-oneplus3t.img
should have made your phone reboot and enter into the TWRP image that you had on your PC.
If it didn't then you did sth else wrong before that.
Either you didn't OEM unlock your phone when you still could or you didn't use the android platform tools that I linked or you don't have the correct ADB drivers installed on your PC.
Start from there.
Hope that helped!

Thanks for your help @KeyperOS - I know where I went wrong...
To save some time, when I tried to reboot into TWRP, I typed "fastboot boot " then I dragged and dropped the TWRP img file onto that line in the cmd window (rather than typing the filename manually) - when you do that, it appears to include the full path to the img - it was that that was causing the problem.
When I typed the TWRP filename manually, it worked.
The only thing that caught me out was after I'd installed the ROM (via adb sideload) I tried to reboot the device from TWRP recovery - this seemed to just hang. In the end I just powered off the phone using the power key, then powered it back up as per usual.
Checked that the phone booted to the first of the setup screens, then powered off/booted into fastboot mode, relocked the bootloader and it seems to be OK.
I'm now back on 3.5.4 again, which was what I was trying to do...
4.0.0/1 had felt a bit laggy, and I'd sensed some issues with wifi and BT, I can now run 3.5.4 and see how it compares - was I just imagining it?
Thanks again for the guide and your help - I really appreciated it

@PugRallye
Windows' command prompt has an autocomplete feature. If you want it to add the name of a file, type a couple letters and then present TAB, it's gonna complete the filename itself and if it's the wrong file you can keep tapping tab to cycle through all the options.
Really glad it worked out Btw [emoji4]
In my experience, 3.5.4 was great but 4.0 is a step up in both battery life, which IME is amazing and features, with it I almost didn't need root and certainly don't need xposed which was a first.
