Problem flashing custom recovery

Just get my nexus, i unlock it root it and try to install twrp through nexus 4 toolkit...when im on flashboot i choose reboot recovery but nothing happens...also i notice that i have a bootloader* version mako10o ( i see only 10i and 10I exists correct me if im wrong)
Edit: somehow with nexus root toolkit i manage to flash it..even with some difficulties....
so anyone else has this bootloader?i have the nipples and the smaller "hole" in the back camera too!!
Don't use a toolkit and learn to do it all manually
I know who to make it manually even than from my old phone its a bit different..but i unlock,root,change recovery in 1st hour the phone came...
You probably types the wrong command or didn't place the file in the right place.
Anyways, you can just flash twrp using the too manager app from the play store.

Reboot problem

Hello. I have a problem with my nexus 4 randomly rebooting. I press the power button to bring on the screen but instead get a reboot followed by the powering down screen. I then have to power on again to get back to normal. Anyone else had this problem? My phone is unlocked rooted stock.

Are you uv'ed at all? That sounds like instability due to low voltage. I've had that happen before on wake.
Edit: I know you said "Stock" but I thought I'd ask.
No just stock settings. Logcat shows lots of errors that i dont understand including SPAN EXCLUSIVE EXCLUSIVE and Fatal Signal 13

many of those "errors" you see really arent errors. anyways, if you wantca log of a random reboot, you need to run a last_kmsg after you boot back up. itll show why you had a random reboot. if you rebooted manually after your bootup after the random reboot, then its too late. last_kmsg is produced by your phone when the device reboots on its own.

Did you just recommend he use a toolkit?
Get out.
Use the real method.

Ok, good method. Try Flash PA 3.60 good rom, install custom recovery, download zip and gapps, stock no good, no customizations, custom rom best.
Went back to stock everything using fastboot. Locked bootloader unrooted no apps installed and no stock apps updated and yet still getting reboots. Decided to take back to shop. It behaved itself in the shop but they were helpful and exchanged my unit. I now have a model with the tiny feet

PLEASE someone help me... I cant believe this is happening

Ok so i just bought a new lg g2 d801.
I unlocked it succesfully, then went on to root it succesfully using ioroot.
Then I tried installing twrp using freegee and it didnt work giving me comparable results to this: http://forum.xda-developers.com/showpost.php?p=50501346&postcount=867
so I went on to install it manually from terminal emulator (I installed the rogers version as suggested by another user here as this is exactly my situation: http://forum.xda-developers.com/showpost.php?p=50502408&postcount=869
I followed this method for the code in terminal emulator:
su
dd if=/sdcard/recoveryfilename.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery
replacing "recoveryfilename" to the name of the rogers .img.
Now the phone just boots normally into the stock interface but it is all glitchy, no wifi, computer doesnt recognize it and then within about 1 minutes it boots into the lg logo with the "turning on" sound randomly and keeps doing that.
adb devices gives nothing. I cant browse the contents of it but it does seem to be interacting with the computer since it is saying "driver updating... etc."
Ahhhh not too sure what to do from here.
If anyone can guide me I will be infinitely grateful, so discouraged right now.
I just want to bring it back to stock, nothing valuable at all on it, I have had it for 4 hours.
U can do a factory reset and see how it goes. Go to settings > general> backup and reset> factory reset.

I cant access any settings.
Just says: Error
In a little black box. I can browse the menus but cant actually enter into the specific settings areas.
I did factory reset from twrp which is accesible, didnt help.
Thank you though, I would love more ideas!
In that case u should flash stock rom using a computer. Go through this thread http://forum.xda-developers.com/showthread.php?t=2432476

Ok im going to try using the lg mobile support tool
I went in usb mode holding the up key and inserting the usb cable.
Seems to be working, downloading a ~2gb file.
I will update.
All the best
Sent from my LG-D802 using XDA Premium 4 mobile app
of course my wifi cuts when the download is at 1443 of 1772 mb.
I think the gods have something against me today.
Should I cancel the download and start over? Doesn't seem to be picking up where it stopped.
Do you have any other option to resume ur download?
Sent from my LG-D802 using XDA Premium 4 mobile app
OK thank god it went through.
Installed the stock recovery succesfully.
Restored factory settings.
Still doing strange boot shutdowns randomly and wifi is not working. I cant access any settings.
It seems like there is rom compatibility issues or something.
What should my next step be?
Btw thank you so much for being here I really appreciate your help.
Did u flash the stock rom or just recovery?

Just recovery I think... I just let the lg mobile support tool do its thing
It was in the usb download mode.
Now I am planning on attempting what you linked. Only problem is that the flash tool links are not up to date and I cant fidn where to download it.
U should flash the whole stock rom, not just recovery, u will find all the necessary tools in the thread I mentioned

I am actually going slowly insane right now.
I have been sitting in front of my computer for over 8 hours trying to get this back to functional condition.
I followed the procedure exactly as detailed, when I press "upgrade start" I get this:
Please install CSMG B2C Client Tool" "Select tool ->B2C Client setup
Absolutely discouraging. I wish I could just talk with someone right about now. I am making no progress.
Phone keeps turning on all the way through til the homepage then off again. I actually cant keep it off. It turns on by itself.
adb devices is now recognizing it but it says "offline"
Ideas? Recommendations?
I really appreciate everything so far
Did u run that update tool before running the flash tool?

Thanks cccho. looking into this now looks like it could very well work.
I actually didnt even sleep last night. Havent done that in a long time, I figured I would manage to figure out by morning but I was not even close!
Much love to all who helped.
Hopefully this works.:good:
Actually I have a question... In your link they are using .tot files. I have only ever seen .kdz files for this purpose... Am I safe to follow the procedure with a stock .kdz file?
Thanks
Ok so I have managed to succesfully reinstall the original exact videotron firmware that the phone was running just one day ago.
There is something else going on. Its still rebooting every 10 seconds, whenever there is a text input prompt the cursor goes when I press within the box but the keyboard never appears. Wifi is non functional. Imei is saying "null" now whichI find extremely worrying...
Anybody heard of this before? I would really love to understand what is happening to this seemingly incredibly fragile phone.
Im about ready to toss it in the trash.
It seems like it has a virus or something.
Every now and then during the short glimpses of functioning it undergoes, there is a small grey box that appears near the bottom that says error.
It is not recognising my sim card either.
Please somebody help me out, I am willing to pay for help at this point.
Much love,
Zach
Also, I can never close/lock the screen. If I close it, its a guaranteed reboot. Every signle time. so for the phone to work screen has to stay on. 24 hours ago it was showing absolutely no signs of any of this

[Q] Just keeps showing the boot logo

So im trying to fix my cousin nexus 4 but i tried everything to get boot but it won't past the boot screen. I adb several roms to it but it stays the same. I did notice there was no files at all whatsoever. I gonna try to factory reset it with a toolkit soon but at the moment has anyone encounter this issue?

Can't upgrade from 2.2

[Resolved]
Help, I downgraded from 2.3 to 2.2 for various reasons,but now when I try to upgrade again I just get the pink screen ,if I try using the option from settings/storage,it says key data couldn't be backed up , the installation will stop. Also if I boot into the system it runs fine for about a minute then locks up completely so I can't even continue to use it in 2.2 can anyone advise ?
Sent from my Nexus 7 using XDA Free mobile app
Try to put the 2.3 dload folder to a sd card, then remove the battery, plug in a USB cable to the computer and the phone, volume up+down+power (if I remember right lol). See if it will update that way.
no, that's the usual way I've been flashing it, I can get to the image folder ,but it won't boot into recovery either

Odd. Maybe try to flash the ICS pink screen unlocker? I had weird issues at some point too, then I flashed that and the problems went away. Afterwards flash ICS.
Just tried that,still no luck,it doesn't even get to the unpacking screen,it just stays pink. beginning to think its beyond repair

I think it's still possible to fix it. I was loosing hopes too, but I messed around with it anyway and got it working. Just try different dload's, different methods and maybe you'll get it running. Maybe other users will have some ideas too.

As long as your phone still gets power and pink/blue screen shows there is nothing to be afraid of yet,since this isn't a hardbrick.
Contact me on hangouts telling me what you have done resulting in the above issue.

Hi there!
I think when you upgrade from software menu there is an option for data back-up.
Uncheck this option and the error should go away.
Also what do you mean with this: "Also if I boot into the system it runs fine for about a minute then locks up" ?
What do you mean it locks up? Touchscreen is not responsive for example?
My suggestions:
1) Do a factory reset and then check if you can upgrade
2) Try re-installing your recovery(use cwm 5.0.27 by geno for best compatibility) or even replace the whole image folder with the froyo one from here: http://forum.xda-developers.com/showthread.php?t=2146856
Your phone is not beyond repair that's for sure. Since it boots fine.

I haven't noticed an option for data backup,will check again later on. And yes when it locks up touch screen becomes unresponsive and none of the buttons respond either. Also when I try to enter recovery ,both custom and stock, it displays the kernel logo then vibrates with a black screen for a second then back to kernel logo and continues to boot.

Ok guys,I copied over the stock image folder and now it works ok, however I still can't upgrade from froyo. At least I can use it again though so thanks for your help, its much appreciated. Incidentally, there wasn't an option to back up data when upgrading, but that error has now gone, except it now just reboots instead, so I will just keep trying.

[Edit] Finally I've managed to upgrade to GB , had to put both step 1 and step 2 in the same dload folder and it worked. So cheers for the tips
You've put all steps in one folder?

Steps 1&2 in dload folder ,step 2 renamed to UPDATE_G.APP.
Didn't use step 3 as I was updating to ICS after that
