[Q] CM7 and Stock SBF Soft Brick

You're all going to have to forgive my idiocy, but I have a problem. I installed SM7 in my Atrix on an unlocked bootloader. I decided to go back to stock today and downloaded and flashed the SBF through RSLite. Reading now, you're not suppose to flash a previous sbf version if your bootloader is unlocked, but I didn't know that, at least that's what I'm assuming happenned. Now, the phone goes into a loop on the Motorola animation and does nothing. I can get into fastboot, recovery, RsLite mode and all of that, but the phone itself is in a loop. My questions is, what (If anything) can I do (eg. flash, fastboot etc) to go back and fix my problem? That battery already died once and I found a way to charge it so I can get back in those menus, but any tidbits would be majorly helpful.

If you can get into recovery, flash a fruitcake.
Make sure to data wipe & cache wipe beforehand.

I tried going into recovery mode; no dice. Droid error icon showed up. What's this I'm reading about flashing using fastboot? Can I download and flash a fastboot file so as to fix my phone?

Tried full wipe using fastboot? That pulled me out of boot loop once.
There are instructions and batch files to automate it somewhere in development forum.

if ur ATnT then screwed for very long time(till there is a fix)
if ur international/bell user (i am bell user and i messed up mine big time) then download the bootloader unlock SBF (IHOP_Bell) and flash it via rdslite and this will give u back the bootloader unlocked logo on ur boot screen.
if yes then ur lucky connect ur phone in fastboot mode and remove every **** out of it
fastboot erase boot
fastboot erase system
fastboot erase webtop
fastboot erase userdata
fastboot erase cache
then flash latest recovery via fastboot (do a search in forum ull find it)
boot into recovery and mount ur memory card as a usb mass storage device and copy the fruitcake or any other rom's zip file into it and flash it via recovery and u should be good to go.
since i am bell user i was able to flash back 2.2.2 french rom via SBF and RSD but after flashing cm7 i am not touching rsd or any sbf for that matter.
Press thanks if i helped you, and if i didnt then press it anyways

i would say do what swiftks says
flash a fruitcake use fastboot its your
only hope now also swiftks has guides
in his signature

Yer not hard bricked. You'll be fine. PM swift or myself if you can't figure it out.

[Q] N4 stuck in boot loop after OTA update

Hello,
I saw that the OTA update to Lollipop was available on my phone today, so I went ahead and let it download. Upon completion of the download, it restarted and applied patches, then restarted again and has been stuck in boot loop for about an hour. After reading several other threads on how to try to reset the phone, I'm stuck. When I try power + volume up or down, the LED status indicator flashes red and I never get to any kind of other screen. Am I completely screwed? I previously had stock 4.4.2 with no modifications.

Finally was able to get to the bootloader menu. Apparently having the phone plugged into the charger was preventing me from getting there for some reason. I ended up having to wipe the phone to get it to boot

so you can get into clock recovery right? download nexus 4 toolkit..that might save your phone. I suggest you to unroot and flash everything to stock and then unlock again and start everything from scratch. good luck.

Similar issue on an OTA upgrade to an unrooted N4. It's stuck on the Lollipol boot screen with the rotating Circle thingies.
I can get to the Android System Recovery but there's no CWM or TWRP on my N4. I'm guessing a factory reset will fix it but is there a way to preserve my pics/files on the phone before doing so?

I guess TWRP Recovery has option to enable MTP and you can access the internal SD card by connecting mobile with computer using usb cable.

Flash TWRP Recovery using fastboot.
1. If you have otg y cable, connect it and use file manager to copy all the files.
2. OTG method is failed then select “Mount”, then select only “Data” and connect your Nexus 4 to your computer and Enable MTP in TWRP. now you can use adb pull and push commands.

I ended up going the factory reset route, which wasn't really a bad thing. My photos had been backed up in dropbox and the play store remembered all the apps and were able to reload them. The only things I really had to do was reload some music onto the phone and re-enter passwords for apps.

Same story here: sideloaded the OTA zip file, then had bootloop. Tried a few approaches, but none worked. In the end only wiping the data was the solution for me. Lost some userdata in a few important Apps...

I went through this yesterday. The only way to get it to boot is a Factory Reset from Recovery. It works like magic, but sucks you lose the data.

Got the OTA yesterday and also got a bootloop(stuck in boot screen animation). I couldnt afford losing my photos/videos as i had no backup , so i figured out a super easy to get it to boot without wiping data .
I was unrooted with stock recovery running stock 4.4.2, bootloader was unlocked. I flashed CWM recovery through fastboot and wiped chache+ Dalvik from there then simply rebooted the phone .
I had already tried wiping cache from the stock Android recovery,needless to say that didnt work for me.
If anyone else is having the same problem please try the method above and report back, cheers!

I post this on Google Product Forum 2 days ago. Hope it helps

(updated 29/11/2014)[not perfect but it is a SOLUTION]
The idea of this is to downgrade your nexus 4 without wiping your data, which means stuff you will need includes:
1. adb and fastboot on your computer (I am using mac but you can find it on windows as well. There are tones of website and forums telling you the latest method of getting it onto your computer)
2. factory image of nexus 4(I use 4.4.4, since that's what it was. I don't have the time and energy to try to do the same thing with lollipop. you can try can leave a comment).
update: do NOT try to flash 5.0 rom using this method. You will be stuck at boot loop again
3. usb cable
4. nexus 4 with unlocked bootloader(the process of unlocking bootloader will wipe your device)
5. computer
steps
1. unzip the factory image (something.tgz)
2. for me, after unzipping the .tgz, I still find another .zip inside. unzip that too.
3. hold vol+, vol-, and power button simultaneously to enter fastboot mode
4. open terminal(mac)(it would probably be cmd for windows)
5. connect your nexus 4(in fastboot)
6. to make sure it connect successfully, type "fastboot devices". if something like "005040c0d54bb291 fastboot" appears, you are good. Otherwise, try reconnect your device/boot to fastboot again/use another usb cable
7.now we need to tell the terminal to navigate to the location of the unzipped factory image. to do that, i suggest you put the unzipped folder to somewhere easy to find, like desktop. these are some commands to help you navigate:
"ls" allows you to look at whats inside the current directory of the terminal. For example, this is the output after typing "ls" for me:
some folder Photos
nexus4image.tgz how many folders do you have
5.zip occam-ktu84p
more folder occam-ktu84p.zip
after knowing where you are, use "cd" (below) to go to your folder
"cd" means change directory. For example. "cd Photos" will brings me to the "Photos" folder. And then if I type ls, I will see a whole bunch of photos in my photos. If you go to the wrong folder, type "cd ..", and it will bring you back to the previous folder.
8. flash bootloader.
enter the following command, BUT REMEMBER TO CHANGE THE NAME TO FIT YOURS(DIFFERENT VERSIONS HAVE SLIGHTLY DIFFERENT FILE NAME AT THE END(type ls first to help you type the correct name)
fastboot flash bootloader bootloader-mako-makoz30d.img
9. reboot bootloader. just copy and paste
fastboot reboot-bootloader
10. flash radio
enter the following command, BUT REMEMBER TO CHANGE THE NAME TO FIT YOURS(DIFFERENT VERSIONS HAVE SLIGHTLY DIFFERENT FILE NAME AT THE END(type ls first to help you type the correct name)
fastboot flash radio radio-mako-m9615a-cefwmazm-2.0.1701.03.img
11. reboot bootloader. just copy and paste
fastboot reboot-bootloader
12. flash system
system.img is located inside the zip, use ls to help you navigate. This steps takes the longest time, total time on this step is 87 seconds while the others are less then 1 second
fastboot flash system system.img
13. flash boot
boot.img is located inside the zip, use ls to help you navigate.
fastboot flash boot boot.img
14. flash recovery
fastboot.img is located inside the zip, use ls to help you navigate.
fastboot flash recovery recovery.img
15. format cache(not the memory, so everything should be fine)
fastboot format cache
16. reboot and wait
this will reboot your device. You probably have to wait for a while to initialise all the apps. after than you are good to go!
fastboot reboot

[Q] Need help! Did OTA update to 5.0, stuck in bootloop!

I need some major help
My N7 2012 was stock, never rooted. I had only installed OTA updates. Yesterday, the OTA update for Lollipop appeared, and I installed it.
It worked fine for about an hour, until it suddenly rebooted. After that, it will now only boot into the launcher (Nova Launcher) for about 15 seconds, then *bam* crash, reboot. Rinse and repeat.
I've tried booting into safe mode via long-pressing on the Shutdown menu, but it apparently crashes before it can reboot, because it just boots back to Nova Launcher.
I've also tried getting it into fastboot, and I can issue fastboot commands. However, I've never unlocked the bootloader. And when I try to unlock it now, I get the screen that says "This will void your warranty are you sure?" But when I select Yes, fastboot's console says "Failed", and it remains locked.
If I go into Recovery, it just says "No commmand"
I need some help from the geniuses on this forum. To me it seems like an app running at startup is causing the crash, so if I could just get it to Safe Mode, I could figure it out and uninstall it. Hell, I'd be fine w/ a total wipe at this point. Just something to get it working again!
Thanks in advance!

Try using wugfresh's nexus toolkit to fix your issue, preferably to full wipe and reinstall lollipop again.

Didn't work

I tried using the Nexus toolkit, using Flash to Stock/Unroot in Bootloop mode, and it didn't work. A few sections succeeded, but most of the sections said "FAILED". Even after performing this, it still wants to boot to my normal desktop, so I know it's not re-flashing a thing.
I wish I knew more about this. I can get into fastboot by going to Power+VOL- but because it won't stay on the desktop, adb commands are a no-go. Is there something in the Advanced section of the Nexus Toolkit that will let me do a reflash? I'm afraid of just poking and trying things for fear of truly bricking it.
Thanks.

Sorry just re-read your last reply didn't realise you can't do adb commands, if you get to a point when you can then below may help...
I had a similiar issue caused differently what i did was to go to this link
http://forum.xda-developers.com/showthread.php?t=1907796
Downloaded the bootloader from JWR66V the guy mentions in his thread he mentions the same issue that i had which is when i tried to flash a stock or custom rom i kept getting messages about invalidstate on bootloader then the system and userdata images would fail when i tried to install...
In the end i downloaded the stock JWR66Y rom, replaced the bootloader image with the one mentioned above, i had to flash the seperate parts of the rom as the Nexus Root Toolkit wouldn't accept the MD5 after i replaced the bootloader so make sure the recovery, the modified bootloader, system and userdata are in your SDK tools folder then i did the following in cmd...
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
fastboot flash bootloader bootloader-grouper-4.23.img
fastboot reboot-bootloader
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot flash userdata userdata.img
fastboot erase cache
Fastboot reboot
And voila it booted up and then upgraded its self and is now stock running 5.0 but its working for 2days it wasn't lol

You can try booting into Safe Mode directly from powered off state. From a reference guide here in help

[size=+1]Safe Mode Boot[/size]
From a cold start boot (press & release Power button), wait 2 seconds after the B&W Google (bootloader) splash screen appears, then press and hold Vol-Down button until the normal OS boot is fully completed (lock screen or home screen appears)

Sounds like something is draining the RAM. Try using the stock launcher as default.

I didn't know that. I tried it, and I was able to boot it into safe mode doing this ... and then it crashed in 15 seconds and rebooted...
At this point, I'm considering just emailing Google, since its their update that did this.

They'll probably tell you to wipe cache partition. And by the way,
alastria1 said:

Click to expand...

that is a normal operation, it's supposed to say that. What you need to do to get the actual recovery menu is, with screen saying No Command, hold the power button, then click the volume Up button, them let go of power.
This will get you the recovery options, where you should scroll down to wipe Cache partition (last one I think) and select it by hitting power. Reboot into Android and see if that helped.
If not in the same recovery menu there's an option to wipe everything, factory reset. that might cure your device but it will wipe your data.
There is an adb command to pull your sdcard data off your device, but I've never tried it in stock recovery. it might work, but of course it will probably require you had turned On USB debugging.
adb pull /storage/sdcard0/ yourcomputerfolder
yourcomputerfolder being a location on your laptop, like a folder on the desktop.
try this command when in recovery, I don't think it works in bootloader. also, if it works it will only backup your regular files, not your installed apps.
if not then just do the wipe from recovery.
good luck.

Still a no go...
So, I got into the recovery menu, and did a full factory reset. After it rebooted, it went right back to Nova Launcher (with my usual wallpaper on there), and crashed as before. Getting into safe mode confirmed that it no apps were wiped. Factory reset didn't reset a thing.
Its almost like the flash memory is stuck on read-only mode. No matter what I do, nothing changes the contents of memory.

That is weird. And I suppose you can't do what 'wakers' suggested and flash the individual partitions since it probably requires an unlocked bootloader, which you already tried to unlock unsuccessfully. I'd say you were up sh-- creek without a paddle, but... Google searching, maybe there's still a tiny bit of hope:
See this discussion: http://android.stackexchange.com/qu...p-after-lollipop-flash-no-adb-and-no-fastboot
to summarize the suggestions:
- try holding the power button for over ten seconds to kind of reset... something
- try sending the command: fastboot oem lock
yes I know you never unlocked but try it anyway, it might go thru where unlock failed.
speaking of fastboot oem unlock, I know it failed but maybe you can just keep sending the command a few times, one of them might go thru.
I'd add another suggestion: carefully remove the back and carefully unplug the battery and let it sit for a while. then put it back together and try booting up.
may the force be with you.

Finally resolved
Thanks to the posters for the help. I contacted Google customer support and they're overnighting a refurb replacement for free.

Bricked VS995 after Dirty Santa attempt - could use some help! :(

So my VS995 (Verizon LG V20) is stuck in a fastboot loop. I can't do anything outside of fastboot. I got to after step 3 in the Dirty Santa root method and could not get the phone to boot into TWRP recovery. I kept getting an ADB device offline error and could not get ADB to see my device to initiate the "ADB reboot recovery command".
In a stupid and drunk state I did a "fastboot erase system" and thats what locked me into the fastboot loop.
Any help is appreciated as my V20 is now unusable :crying:.
I guess I would need a stock boot image, and stock recovery to get back to where I started. If anyone could point me in the right direction and help me get my phone back (and possibly rooted), I would be more than happy to donate via PayPal .
P.S. The LGUP software used in the how to restore v20 thread linked-> ( https://forum.xda-developers.com/v20/how-to/restore-v20-to-100-stock-bricked-devices-t3524903) does not recognize the model of device giving the error ("you have to select a known model, please")

to my understanding, the kdz file contains the stock boot.img and stock system.img, everything to bring the device completely back to stock .
In fastboot to boot to the system the command is "fastboot reboot"

Did you flash the kdz using Uppercut?

imucarmen - I can't post in the dirty santa thread because I am a new member to XDA (been coming here for years just never made an account )
bond32 - Yes I was able to flash the .kdz using Uppercut+LGUP but my problem is not fixed. My phone still boots right to FastBoot Mode in the "Locked State" to where I can't issue any commands or alter any partitions.
This makes no sense to me if LGUP is able to 100% flash the stock firmware, WHY CAN'T I GET OUT OF FASTBOOT! Lol
Does anyone have any ideas as to what I could try to unbrick this thing?

I know it's a different issue from the one that I had, but the LG Support Tool method that KedarWolf posted might help solve this issue too.

Did you try pulling the battery, put the battery back in.
Hold the volume down and power button at same time. When the lg logo shows up let go of the power button but continue to hold the volume down and press the power button again. It will bring you to a screen tgat has 2 questions. Answer yes to both of them. Then reboot. I believe that resets the way the phone boots almost like resetting a cmos

hold the vol down and power and put in battery as soon as its on click the power button and re hold it. it will get to recovery, it took me hours but its there.

I had tried that a few times after reading about it but I'll try now for an extended period of time and see if I can activate it. I'll report back with what happens, thanks for the tip dwertz and Team DevDigitel

Well I got in to the recovery menu and reset to factory settings and wipe cache (the only two options) but I still am booting right into FastBoot and can't escape!
I even flashed the stock .kdz again after the factory reset and wiping cache and I'm still stuck in FastBoot

When you have a unlocked boot loader and you do a factory reset, I believe it wipes the OS from the phone giving you no OS. If you can get back to recovery, flash this rom https://forum.xda-developers.com/v20/development/vs995-vzw-nrd90m-modded-notsostock-rom-t3525864
That will at least get you booted so you can flash the kdz.

I can't get into any kind of recovery to flash a rom though

Same problem here, did you ever fix it?

OEM Loop

So firstly, eff this phone. First phone I have had real problems with.
We rooted following methods on this forum. Once TWRP was installed I flashed a custom rom and once it rebooted it was telling me an error beyond the google your device is unlocked message and gave me only one option to factory reset.
I went with that option after 4th reboot and now it only reboots to the google unable to verify corruption. I have tried fastboot and pushing TWRP, but it fails.
Since I am on Mac i decided to install windows 10 and use Uppercut. I followed all of the steps, but the device isn't being recognized. Verified drivers installed, but I have very limited windows experience.
Any ideas would be appreciated. This is a 1 day old v20 and I would like to not have to buy another phone for the wife

So firstly, eff this phone. First phone I have had real problems with.
We rooted following methods on this forum. Once TWRP was installed I flashed a custom rom and once it rebooted it was telling me an error beyond the google your device is unlocked message and gave me only one option to factory reset.

Did you accept to give authorization to your computer prior to do all this? if you didnt then it will never recognize your device in fastboot mode. But ... If you cant do anything beyond going into fastboot mode, then i suggest you use LG up and use the kdz for your phone and then... voila! problem solved. Assuming that your variant has released a kdz. (when you download the kdz, use LG UP refurbish function while your phone is on download mode (not on fastboot mode). To enter into download mode follow this link: http://www.hardreset.info/devices/lg/lg-v20/download-mode/ .). If you do all this, then you should be back into stock and can try once again to get root.
So, it is basically:
1) download LG UP & your kdz file
2) go into Download mode on the phone
3)use refurbish function on lg up and use the kdz file

You have to formatt data with twrp!!!!
Format data
It requires you to type yes.
Then flash stock rom.
This is part of the unlock procedure.
Device needs formatted not just wiped to remove the encryption that was on it.. Once done then you can flash a rom and boot.

2nd.. If you have fastboot and the above was done and your still not booting
Fastboot erase system
Fasbtoot erase data
Fastboot erase misc
Fastboot erase fota
Fastboot erase cache
Fastboot erase etc
Then pull battery and reboot to twrp. Install rom and reboot and wait 15min. Most take atleast that long 1st flash.
