Gnex no baseband - cannot flash or relock

Not sure if anyone else has seen this?
A collegue of mine woke up to find his gnex not booting. I've got into the bootloader and it shows as no baseband and he also has no recovery.
I've tried flashing CWM via fastboot, which succeeds, however if you try to boot into recovery, it goes back to the bootloader stating that no recovery or boot is available.
I then tried to flash a radio, however had the same issue. Fastboot says a success but the bootloader says no baseband still.
Also, when rebooting bootloader, instead of powering off, the screen effectively dies/greys out.
Any ideas? I've tried reverting to stock using the Google images with no luck. Also tried to relock the bootloader - it succeeds, says so on bootoader, however on reboot it still says its unlocked

Sounds like there might be an issue with the flash memory?

Possibily. Seems a little odd that even the bootloader won't remember if its locked or unlocked. He's managed to get a replacement (even though the bootloader clearly states that it is unlocked)

The settings/changes made in the bootloader not sticking is (to me, at least) indicative of a hardware issue.
One last thing to consider - have you tried reflashing/updating the bootloader? There are instructions and links to the files needed in this thread: http://forum.xda-developers.com/showthread.php?t=1391881&highlight=flash+bootloader

Yep, flashed the bootloader several times using all 3 sources from Google to see if it made any difference. Same story - success but on reboots it never seems to remember

Boot Looping Help Please

I purchased a 5x for my wife so she can get on Project Fi. They said it was stuck boot looping, thinking I could solve the problem.
Here are the basics.
-Yes, I can get into boot loader (the menu of start, recovery, etc), but I can't get into TWRP. Tried flashing TWRP a few times and nothing. SkipSoft recognizes that its installed though.
-After bootlooping for awhile, it will load normally and work fine. However it wants to update to the newest version of android. I run the ota and back to bootlooping. It will show the android dude and say "error". Will eventually start bootlooping and then boot normally.
-I have flashed different stock versions. I tried the newest, the second to newest and the last M available. All will flash but continue the bootlooping.
Bootlooping can be anywhere from 1 minute to 10+.
The device will also first display something like, "Your device software can't be checked for corruptions. Please lock the bootloader"
But it'll show up whether the bootloader is locked or not.
The phone will freeze at some point. Whether right away or after 5 minutes. It freezes and then restarts and goes through the bootloop again.
So what else can/should I do? I've never dealt with Kernels but wondering if the last owner did something to them. Is there a way to flash stock kernels just incase or is this done when I flash a Google Factory Stock Image?
Would flashing a non-stock rom be a good idea?
Thanks

So I tried sideloading. I was able to get into the stock recovery. I tried wiping cache and data, then tried installing the newest stock rom.
Everything seemed to work. Then I had to restart. A message popped up after the same "Your device software can't be checked for corruptions. Please lock the bootloader". It had the title in blue stating "Encryption unsuccessful".
Then said, "Encryption was interrupted and can't complete. As a result, the data on your phone is no longer accessible. To resume using your phone you need to perform a factory reset. When you set up your phone after the reset, you'll have an opportunity to restore any data that was backed up to your Google Account."
Then there is a single button that says, "Reset Phone".
Problem still persists.
Help please...

Why did you bought a bootlooped phone?

When my Nexus 5x got into bootloop, I sent it to LG and they had to change the whole circuit. So yeah.

When you flash Google Factory Image, it flash the stock kernel.
If you have warranty, then send it to Google/LG. If you haven't got, then you're in problem. New motherboard needed, but it's expensive.

See the following thread for more info.

Exactly. Everyone has either been able to get a replacement under warranty or was pretty much screwed if it was out of warranty.

various issues with google variant

I've had Google phones for years now, including previous Pixel, but I just got an XL 2 yesterday and I'm regretting it.
It's Google unlocked and running June's latest image. I've experienced various app crashing on stock, and random reboots.
Then there's the rooting and flashing. I unlocked the bootloader and installed the most recent, twrp (the one verified to work on xda for roms) but can't flash anything.
My twrp either hangs on the twrp start screen, or when it does load, the touch screen doesn't work. When I can get it going, every rom I flash gives me an error on the second step. I'm flashing on slot B by the way, that's what boots up when I boot to twrp.
Lastly, I am unlocked both for flashing and flashing_critical thru adb, so I'm at a loss and seriously confused.
When I FIRST unlocked everything, I was able to flash Nitrogen rom but I got stuck at the rom splash screen.
Tldr:
-What is the Correct install method/sequence for roms?
-do the slots matter?
-is random reboots and app crashing on stock a sign of a hardware issue?

I haven't installed a custom ROM on my P2XL, so I'm running rooted stock. Anyway, for rooted stock, this is what I did.
Entered bootloader mode.
Booted into recovery using the command "fastboot boot recovery.img", where "recovery.img" is the TWRP recovery iteslf. In my case, I renamed it "taimen.img".
Flashed the TWRP installer zip needed for the P2XL (Required if intending to replace the stock recovery).
Rebooted into recovery.
Flashed a custom kernel (Recommended - resolves touch issues in TWRP).
Flashed Magisk.
6. Rebooted.
If installing a custom ROM, flash it prior to the custom kernel. Slots only matter if running stock. Random reboots and app crashes are not signs of a hardware issue.

Ya know my friend, after our conversation yesterday, and your questions in the nitrogen thread, and now random reboots and app crashes, I think it's time to consider a factory reset. You shouldn't be having those problems on a stock setup. If that's not successful, then I would definitely consider an RMA. Just my 2 cents worth :good:

I agree. I got it used tho which is an issue.

Just so you know, I got the rom to flash finally, but it's stuck at the rom splash screen during first boot. I'm going to leave it and hope it eventually boots up.

If it doesn't after 5 minutes, do a hard restart with the power button. If that doesn't work, then reboot to twrp and flash the rom and twrp installer zip again.

Ok cool thanks. I relocked bootloader last night and went back to stock. Unlocked it all this morning from my work computer and different unlock app. So here's hoping.

What did you do to get it to work? You could just flash the June vendor.img to both slots. If you keep getting a vendor mismatch, probably nothing to worry about according to the Dev of nitrogen.

Different machine, cable and unlocking tool.
But I went to bone stock with locked bootloader, then flashed the newest twrp with the newest all in one tool. Was on slot A so wiped everything and flashed rom plus twrp again. I rebooted system to slot B, but then it just hung at the rom splash screen.
So I did it all over on slot A, ignored the "no os installed" message and booted anyway. Then it fired up. Rebooting into twrp from there took me to B, which is where I need to be for an image file or root.
So yea, thanks for the help.

I'm having this issue also. I tried flashing nitrogen, it hung. I tried to go back with factory reset Img and nothing happens in adb. Flashed the may img and it wouldn't boot all the way up. Now I'm stuck in bootloader trying to figure this all out. Seems like nothing in doing is working. I can get recovery to boot, but no files inside so idk. Tried to sideloadb nitrogen, but it said adb out of date for device when sdk is fully updated.

You didn't mention the out of date message in your other post, but uninstall SDK and then download the stand-alone adb/fastboot binaries from May of this year. Dump that in a folder (eg. c:\adb) and put that folder in your path statement. Manually flash the full factory image without modifying flash-all.bat. Post your screeen if you have any errors. :good:

Google knows the date the phone was purchased based on imei number and honors their warranty by date, not owner. Unless it was blacklisted.

Weird bootloop with locked bootloader

Long story short, I ended up with a classic bootloop (shows boot animation continuously) from messing around with Magisk modules, so I did a wipe from recovery, still bootloop, so I tried reverting completely to stock with the OEM downloads. I tried flash_all_except_storage.bat, and flash_all.bat, but this time it was a different bootloop. The phone shows the Android One logo, the screen flickers like it's going to the boot animation, but then it just goes back to the Unlocked Bootloader Warning Screen, then the Android One logo, and loops like that. I dumbly thought locking the bootloader, reflashing everything, and starting over like it were a new phone would fix the issue, so I did flash_all_lock.bat, but now I'm just stuck with this weird bootloop and a locked bootloader. Trying to unlock the bootloader with fastboot just gives me "oem unlock is not allowed", so I'm at a loss here.
Does anyone know of anything else I could do, or is this a hard brick?

With a locked bootloader EDL flash probably is your last chance.

I got stuck with a similar problem and that was the only option, to boot into EDL mode you will need to partially dissasemble your device and flash the image via fastboot or via MiFlash (download the latest version as I had problems with an older one). Since that incident I kept the bootloader unlocked just in case something happens.

I had the phone booted into EDL mode and attempted to flash the stock ROM (10.0.3.0) with MiFlash, but it errored out with an ERROR_UNSUPPORTED_TYPE. I tried with the previous version, 10.0.2.0 and it worked for some reason. That fixed it though, so thanks! I've been lightly tinkering with rooting android phones a few years now, but until encountering this issue, I'd never heard of EDL mode. You learn something new every day? ?

I have the same issue with my nephew 's mi a2 lite which has the bootloader locked.
It only shows the android one logo.
I cannot go to recovery mode, but I can go in fastboot.
Changing from "a" to "b" doesn't solve anything and being the bootloader locked is not possible to flash anything from fastboot.
So I've opened the device and I've short circuited the edl pinpoint to be able to flash with MiTool (I've used an old version since more recent ones gave errors when flashing).
I was able to flash both the latest official ROM and the oldest one which I've found ( daisy_global_images_V11.0.14.0.QDLMIXM_10.0 and daisy_global_images_V9.6.4.0.ODLMIFF_8.1 respectively).
In both cases the device still is "frozen" with the android one logo when I've tried to turn it on after the flashing procedures gave me a successful status.
What else can I do?

Samsung j610fn stuck in bootloop even after nand erase and pit flash, please help !

Greetings,
I have a certain problem, i have an Samsung J6 Plus which has suddenly rebooted and since then it just turns on the samsung logo, then it turns off the screen, then the screen flashes and finally it reboots again.
I have tried everything, the phone has a pie binary so i could only flash one rom i found.
But even after flashing every part of OS on its own, performing a NAND Erase and re-partitioning with pit file, i still get the same result. The phone restarts after the flash, and then turns off the screen, flashes etc...
Every time the same, no matter what i try.
Has anyone experienced similar problem ?
I have read about 15 of other threads here with similar problems and tried every solution that works for some people but nothing works for me.

You shouldn't have used the nand erase option, that is an easy way to brick the device when used improperly. I doubt you will be able to repair it with Odin now.

But, you see, i did it as a last option, because i tried to flash several different roms before that, and at first it didn’t let me flash Oreo and older, just failed in odin, because of Pie binary.
So i flashed official pie ( first time only AP, and second time all files), and it didn’t help either, the phone was still acting the same (the same thinh happens like before all the flashing).
I can’t boot into recovery, it ends up being the same as trying to boot normally, and it won’t let me flash other recovery because of the frp.

Sounds to me like the hardware itself is bricked or damaged. If that is the case, the only option is to replace the motherboard.

I'm having the same issue after oreo update for j7 nxt so what i did is easily rooting phone via Magisk!
Ahh,, maybe u have frp lock?
Just google for (Combination rom of your device) then flash it with odin. After that you can go to settings -> about device -> software information -> Build number (click on this option 5-7 times).
Then back to settings you'll see an additiona setting (Developer options) go inside it and click on (OEM unlocking) and cograts you have unlocked frp lock
Note : there is a fairly chance that you won't find this option (OEM unlocking)! So what to do? You just need to trick the phone by changing the date/time for 2014 and restart then check if it's there if still not there just try again with different dates for ex. 2013 and restart (keep doind this and every restart check the developer options section, Just KEEP TRY!! until you find the button there in developer options
After that go flash the stock rom then install TWRP then ROOT via Magisk and you're all done

OEM unlock does not "by itself" remove FRP, there is more to the process than just enabling OEM unlock, removing the Google account from the device and disabling MDM(find my device) is what actually "unlocks" FRP.

Since he didn't mention about getting this message "only official binaries are allowed to be flashed"
Then itsn't something related to RMM.
Also as what he said he can't flash TWRP as he gets "OEM LOCK" it's also called "FRP LOCK" the type of lock i'm talking about is in (download mode) that doesn't allow to install custom binaries, so the only solution is tirning (OEM lock) option and that's enough to flash custom binaries such as TWRP.
The type you are talking about seems to be RMM lock which could be fixed using Miracle Box but as it's not allowed to dicuss this stuff here in xda + his problem is frp locked and phone doesn't booting, so the only solution we can provide in this situation is Combination rom which will boot even if you bricked your phone, even if you've Rooted and bricked your device's kernel (even if it won't boot anymore).. combination should boot, i faced the exact issue but as i explained in my last post. And hmm it could be 80% the solution.
Thank for your reply.

No, I'm talking specifically of FRP lock.
The point you make about binaries has nothing to do with FRP. Binaries can be blocked on both FRP locked and FRP unlocked devices. The binaries only prevent flashing firmware with a lower binary than the current binary installed on the device. Binary version is related to RMM or KG state, not FRP. FRP is directly related to MDM and only "partially" related to the things you mention and only because there are other "tamper-proof" elements that "can" trigger FRP. Have you ever noticed that a device that does not have a Google account signed in does not encounter FRP issues when the device is factory reset, but if there is a Google account signed in the device, factory reset triggers FRP? If it were as you you seem to be suggesting, FRP would be triggered on devices that have no Google account associated to them when attempting to flash/modify the device, but this is not what happens.
OEM unlock really only applies to unlocking bootloader in order to flash unapproved software or make modifications to the system partition without being blocked.
