Can't install TWRP. Any advice? - Pixel C Q&A, Help & Troubleshooting

I recently bought a Pixel C second hand. It had the latest software installed.
I want to install Lineage OS, but unlocking the bootloader, rooting, and installing TWRP requires I enter bootloader mode.
Problem is, as soon as I do that, My computer no longer detects the device.
I have searched the forums and realize this is a common problem, but each thread seems to give a different explanation.

Go back to Stock nougat build. Then developer Setting unlock bootloader. Then try usual procedure. Btw you can boot twrp without installing it but bootloader must be unlocked

I attempted twice to downgrade using the nexus root toolkit, but the problem persists; when the device boots into bootloader mode, it becomes undetectable.

Maybee cable problem or change to USB 2.0 port? Or 3.0 port?

I have tried different USB ports on my computer, and different cables, but the problem persists; the tablet is detected as long as it is not in bootloader mode. : /

I think I just figured it out! Opening device manager I was able to see My Pixel until in Bootloader Mode, then I assumed that if I were to install drivers at this point something would happen. I was given a warning that what I was doing could harm my device but I hit continue and then when I typed"fastboot flashing unlock" unlocking the boot loader actually worked! Now I am going to try doing the rest and see what happens!

I ran into the same problem yesterday and also figured it out! Couldn't get Pixel C to come up in Device Manager until I opened Device Manager while the device was in fastboot mode. Device showed up and then I was able to pick ADB drivers.
Now I'm able to fastboot boot into TWRP, but the touch appears to be not working on this device and TWRP is all touch.

I was trying to root my nexus 7 but didnt switch on usb debugging. It is now in a bootloop i suppose (stuck with the google logo and unlocked lock). I have searched on alot of forums and tried them but i think i failed because the usb debugging function is not switched on. I still can access bootloader as well. Please advise. Thank you.
Also, i tried to go to recovery mode but it will go straight to the bootloop
Don't you think it's the normal problem? Try fastboot -w in bootloader.

Try this tool(If you are using the Wifi version, stay clear if you are using a LTE version) :[TOOL] 08/23/13 One Click Factory Restore (dead or alive) updated w/ JSS15Q images, a lot users reported that it works very well for restoring bricked/bootlooped N7s, I once used it to wipe my unlocked & rooted N7 and go back to stock and it worked like a charm.

When you access bootloader, do you see the "START" option on the right of the screen with the arrows going up and down?

You don't need USB debugging for fastboot operations. As a matter of fact USB debugging is only used to conveniently boot the Nexus into the bootloader, so you don't have to press any buttons on the device.

[Q] Mysterious problems with used Phone... HELP!

Hi guys!
So, my sister got a Galaxy Ace II yesterday with some ode stuff, then I decided to install Cyanomod 11, BUT more problems appered:
1 - My Windows 7 (64bits) doesn't recognize the drivers.. so it no even list the phone as conected. I tried using Kies to detect and a bunch of packages of drivers of this smartphone model, but till now haven't made any progress... what can I do?
2 - I reseted the phone to original especifications by his own menu and tried to acess its Download and Recovery mode by pressing the 3 buttons at the same time(Vol UP + Home + Power), but for my surprise it didn't boot like it should, jus initializing normaly...what can I do?
3 - I realized, when it booted, that the boot animation has been changed, samsung logo doesn't apper ever and including I found some stuff installed that doesn't seem to be something that generic stock roms have instaled; this made me think that the room installed is not its stock. If that's so, maybe the problems listed above are resolved, but still so I don't know what to do...
I want to install Cyanomod 11, but need the phone recognized for Windows, it rooted and in download mode, but haven't find a way to begin if my computer doesn't reconize it...
Any Help?

Yes, I hold the 3 buttons at once and waited to it boot, but it jus performed the normal boot, it didn't get into download or recovery mode... I tried many times, but it's always the same...
And I know that CM has it's own boot animation, I know it, but it's not it this time... it's another one... and for what I know, it's not the samsung original one...
Having Kies installed is counterproductive to installing flashing drivers (and if you sync contacts and calendars with Google I can't even think of why you need it :angel
Try unplugging the cable while entering recovery, the LPM mode (charging while "off") screws it up (but download mode should work!)
And by "no Samsung logo", you mean not even the firmware's "Samsung GALAXY ACE 2 GT-i8160"? Sounds like you got a fake then...
But if it boots, you should check the Settings/About menu and tell us the "build version", often that's enough to know what ROM is on it now

Ryccardo, I installed Kies in the hope of having the drivers easylier recognized... But that was not my luck...
About that trick could you be more especific? Do I put the phone off with the cable plugged to PC and when I press both 3 buttons I unplug it?
About the version it is :
DM_BASE_12A_W12.43|sc6820_modem|11-02-2012
And this means that??? It's not the original one, right?
Thanks for the help in advance!

Recovery mode is: with power off, hold up+home+power (if it's on, it will reset since you're holding down power... keep holding it) and download mode is the same with down+home+power...
But that version is VERY dubious, the standard Ace never had "SC6820" (maybe it's the L model?) and I don't even think it was out at the start of 2012...

Googling "sc6820_modem" has http://www.pandawillforum.com/archive/index.php?t-18643.html at the end of the 1st page
2nd post there mentions "Star I8160"
Googling "Star i8160" on images shows http://www.gldron.com/media/tmp/catalog/product/6/4/64cfade20f06e0e31ffd853fb1f8009a.jpg as 5th result... while searching the version number on images shows a lot of Samsung clones...

You surely can't use roms from these forums... There may be other roms for your device but you'll have to find out what it actually is first, which can be somewhat difficult...

[HELP] Soft brick ZL C6506.

Hi All,
If you have some experiences with some situation like this, pls give some advices.
I have my Zl, upgraded to 5.1.1 (10.7.A.0.222) , it work fine for some week, then usually shutdown suddenly, 5.1.1 upgraded from 5.0.2 with rooted, installed xposed and some modules (but not unlocked bootloader) .
After some random hanging and rebooting, i try to flash brand-new from ftf file .
and BTW, i unlocked bootloader, after flash new ftf, system cannot boot up, only show up the Sony logo, then down, after that fastboot and flash older ftf ones normally , event i try to relock bootloader.
while unlocked bootloader, i try to install CM ROM, flash boot.img one but still not up.
While connect the charger, logo sony blink for every 10s (estimation) .
I consider the TA partition affected to booting processs. (i have backuped TA but still don't know how to restore via fastboot/flashtool)
Thank and appricated for reading till this point.
Hope you can give me and someone who encounter this situation some wise advices , i will report each try
This is more clear explanation (just read this ):
My case:
1./ first version is 4.4.2, then i try to flash to 5.02 via flashtool (as i remembered i flash ftf version for Generic US)
2./ Then root/install xpose .... and update to OTA (failed), success with updating via Sony Companion, after that, backup TA.
3./ using normally for some weeks, then occur suddenly hang, reboot, lose signal, i commit to flash a brandnew one
4./ After that i unlockbootloader via sony site, Flash 5.1.1 (10.7.A.222 but customized os)
5./ Try some solutions:
5.1/ (unlocked bootloader)Try to flash some other custom kernel (ex: CM12 kernel, one in this dev subforum) but the symptom as case 5.2 below
5.2 try to relockbootloader install the 5.1.1 Generic US/Customized US still doesn't boot up,
- Unplug charger, press and hold power butter, red light blink for 3 times (although connected to charger all night)
- Connect to charger, not show up the charging progress bar, just blink Sony - Xperia around every 10 s
Still consider to battery issue , hope to hear any experienced/wise advises

Gesendet von meinem C6503 mit Tapatalk
I really need your help guys. My ZL got updated yesterday, and then a random reboot. After trying to repair it, it keeps getting into Flashmode direcly.
It does not boot into system, but flashmode. Tried to repair again with PCC, no luck. I don´t know booting process to figure out and get out of bootloop. I can access fastboot, flashmode, TWRP, with UB. I flashed ROM a couple times via TWRP, but no luck again.
I think something is messed up with partitions or something.
HELP.

completely bricked?

Just openned my N5X.
First boot to enable OEM unlock and ADB debugging.
Used sudo ./fastboot flashing unlock
Then I wanted to upgrade from 6.0.0 to 6.0.1, so I downloaded the factory image
I flashed twrp-2.8.7.2-bullhead.img
Booted to TWRP to ADB push some files and did not flash anyting from TWRP
After first boot it showed Google with the unlock symbol for several minutes, so I powered it down.
Now, if I boot to bootloader it shows a blank black backlight (I know it is in bootloader because sudo ./fastboot devices produces a s/n)
If booted normally, a mess of rainbow pixels is usually displayed (see pics).
Since it does get to the bootloader, I have tried revert to 6.0.0 with a couple different builds but the same screen issues persist.
I tried a bit more force with the following:
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot flash bootloader "name of bootloader"
fastboot reboot-bootloader
fastboot flash radio "name of radio"
fastboot reboot-bootloader
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash cache cache.img
I also have tried flashing using the update script, but still have the same results.
I find it strange on the first stock boot that the display was fine, but after flashing 6.0.1 and then TWRP this started happening. Is it possible the LCD is actually just defective?
edit: can't post link to pics of screen because I'm under 10 posts
I don't know why you used fastboot flashing unlock. This device requires fastboot OEM unlock. I don't know of that is your problem though.

Did you try flashing using the flash-all.bat?
Maybe that wil completely revert the phone to stock.
If not start from scratch using fastboot OEM unlock (see the root guide on this forum) and reflash the entire phone using flash-all script.

Agreed. Not sure what that command is for. Haven't seen that in any of the rooting guides. Flash all the files from the stock image to return to stock and try again would be my suggestion as pious stated as well

You relocked the bootloader in fastboot mode right? You can just fastboot oem unlock again from fastboot. Once unlocked, flash twrp, push and flash a rom. See what you get.

I have successfully flashed twrp (at according to cmd). When I boot to recovery using volume up + power, I get a blank screen. Tring to slide where the twrp screen lock should be does nothing. ADB does not see any devices. I have also tried booting to recovery from the bootloader with two volume down presses and one power button press-- same result.
I have also succesfully unlocked the bootloader again. I have updated my SDK/fastboot/adb/drivers/etc and have run every flash-all script from every build downloaded from the Google Dev site. I have tried all the flash-all.bat/sh on booth Linux and Windows. I have tried using different USB ports on my machine. I have tried using the USB-C to A cable ordered from the Google store and also the USB-C to A cable that came with the Nexus 6P. I used the same procedure to unlock, root, etc my 6P and did not have any issues.
Every time I get the same result that @SlimSnoopOS linked the screenshot to. I get the rainbow screen when booting to Android, a blank backlight when booting to bootloader, and a blank unlight screen when booting into recovery (although adb can't see the device from cmd or terminal).
Based on the amount of time I have spent on this, it may just be time to lock the bootloader and hope the Google Store accepts a return.

I had the same issue once with my lg g2. Turned out that I the issue was with the display. Sent in to the service center where they said the problem was damaged display connectors due to moisture.

I had a similar issue with my first 5x. I was trying to flash the update, I think, but may have been doing other things at the same time. My display all of a sudden showed a pixelated vertical line running down the left hand side of the screen. The line was about 1/2 inch wide. It was visible in the boot loader, recovery and when normally running system. All attempts to fix the issue by re-flashing were useless. I finally sent it back and got a new one. No issues, rooted and running perfectly. To this day I don't know if was something I did, or if the display was just defective.

[ZE551ML] Cant downgrade

Hello there. I updated my Zenfone 2 ZE551ML to Android 6 as soon as it came out (download it manually from the official website) and now i am trying to do downgrade without sucess. I tried a bunch of things alredy but none of them works. All that need the ADB/Fastboot i get stuck in "waiting device". I installed the drivers, i rebooted my PC, my phone and soo on. The only thing i didnt tried yet is sideloading the Android 5 room.
I have a Win 10 and i am from Brazil (yes, the one place that the Android 6 updated made almost all the sensors stop working), idk if that changes anything.

Ok I will keep an eye out for you .
You can boot into system or are you bricked ?

Hello there. I updated my Zenfone 2 ZE551ML to Android 6 as soon as it came out (download it manually from the official website) and now i am trying to do downgrade without sucess. I tried a bunch of things alredy but none of them works. All that need the ADB/Fastboot i get stuck in "waiting device". I installed the drivers, i rebooted my PC, my phone and soo on. The only thing i didnt tried yet is sideloading the Android 5 room.
I have a Win 10 and i am from Brazil (yes, the one place that the Android 6 updated made almost all the sensors stop working), idk if that changes anything.

I has the same problem as you, try connect your zenfone to the usb ports on the rear panel. Switch different usb ports and check for fastboot devices if it recognize your phone. Zenfones seems to not like all the usb ports, Zen max has this problem, too
