VZW Variant - Vendor IMG Error, SIM Card Not Recognized?? - Google Pixel Questions & Answers

What can cause this? My friend got a Pixel with the not-newest firmware and could unlock BL & root, etc, and he is attempting to flash custom ROMs but getting the same result (in the title). Does anyone know why? It is happening reliably on first boot of each ROM flash.

You don't give us much information to troubleshoot with. However, there a good chance you didn't follow the OP of whatever rom you flashed. Go back and follow every step. My guess is you didn't reboot to bootloader AFTER flashing the rom followed by flashing the vendor image in recovery to the newly activated slot.
Could also be any number of other things: outdated fastboot, outdated twrp, wrong flashing order, who knows with this little info.

New in MI4C

Hello everyone.
I live in Brazil and I bought at the Aliexpress MI4C Xiaomi. I haven't received it yet, but I've already started researching ways to use it with another ROM than the original. The seller sends the device with google apps and multilanguage option. So, he makes some modification in the ROM, and says to not update the ROM officially on Xiaomi servers.
I see a lot of complaints about the Chinese bloatwares in ROM and so I wanted to install one that was good, but nothing with applications in Chinese or unnecessary ones.
My question is: in this case the bootloader is already unlocked?
In the meantime, I sent my request for unlocking bootloader to Xiaomi and received the SMS containing a link. As soon as I get the cellphone I intend to do the procedure. There is a risk of bricking the phone?
I’ll do appreciate good links with how-to and good ROM to daily use.
Thank you.
The seller shipping a modified ROM and telling you not to update the official would suggest your bootloader will not be locked. For now only flashing the latest official China dev builds will lock your bootloader.
Getting pre-approved for unlocking couldn't hurt though I guess.. just in case. You might need to have a working Xiaomi framework in your ROM to register your phone once though. If your ROM does not have the xiaomi services, I would suggest either Xiaomi.eu or sMiUI as a ROM, both are pretty much stock MIUI with some chinese bloat trimmed.
But most likely you will not need to unlock your bootloader anyway. You will need to check your bootloader through adb anyway before doing the steps to flashing a new ROM. You will best be flashing your recovery through adb, the instructions can be found through most ROM pages or simply searching TWRP Mi 4C. The command to check if it's unlocked is
Code:
fastboot oem device-info
A very extensive directory can be found in the INDEX thread, first in this forum.

you cannot check the bootloader locked or not by that way. My phone when checking this, gets the input "bootloader unlocked: false" but I can flash other recovery freely.
in his case, he is using a modified rom, it means his bootloader is not yet unlocked. Right now, if he wants to come back to chinese rom, he should use Mi flash to flash his phone. If he wants other rom like CM13, he should download the latest TWRP and the rom, put the rom into his phone storage. Then try to go to fastboot to flash the recovery, then go to the recovery and flash the rom.

Ah, that might be incorrectly reporting indeed. In any case when trying to flash recovery, if you're locked it'll simply fail and won't be harmful.
But why would you think his bootloader is not unlocked? If he's using a modified rom, it was probably flashed through fastboot or a custom recovery, both require the bootloader to be unlocked.
But even if he was not on a modified rom, stock Mi 4c have always come bootloader unlocked. Someone would have to have gone out of their way to lock the bootloader and I doubt any reseller would do that, they would risk a lot of refunds from angry customers.
I strongly advise against using miflash to flash any official rom unless you have no choice, since then there's a chance you WILL lock your bootloader. For now only dev builds are locking it, but the next stable release might very well too.
The first step should be to flash TWRP
The second step to stay away from Official China build
The third step to keep away from Official China build
The fourth st...
^ sorry my bad.... I was not focused. Actually I mean his bootloader is unlocked .
The safest way is flashing via computer, using mi flash or flash twrp image. You are right
1. Ur phone not lock bootloader
2. U can flash custom recovery...(TWRP)
3. "MUST" Stay away from official MIUI ROM
4. Flash whatever u want...sMiui, CM13, etc,etc
5. Remember Point No.3
***Btw, download official Fastboot ROM and keep it to ur drive, for just in case if u want to sell it again
Hello. Thank you all. I just received my phone. Great, btw. I'll read again and again all instructions and try. Thanks again!

Even as a last resort to getting your phone working if you did something wrong, please don't install the newer official roms, it's the mistake I did this weekend now I have a locked phone with a rom that has force-closes everywhere and absolutely no way back.

yes, or the safer way is always flash the latest chinese rom via miflash. twrp does not like Chinese roms

No.
Don't flash the latest chinese rom.
No.
The only scenario where you would want to use miflash to flash a chinese rom would be as a last resort to flash the fastboot version of V7.1.6.0.LXKCNCK to restore your phone. Any later version will lock your bootloader.
If you don't care about locking your bootloader and the arduous process of unlocking it, you're easier off just taking all the latest updates OTA via the updater.
Hello everyone. Thanks for the help. In fact my bootloader was unlocked. I flashed twrp 3.0.0.3 and flashed the CM13 teamluminial, Android 6.0.1. Excellent. Thank you.
Hi!
Same scenario here..
I will receive Mi 4c with the Bootloader Unlocked, Rooted and the Multilanguage ROM.
But I have already received from Xiaomi after my request also the number for the official unlock procedure but now I'm a bit confused..
Do I have to unlock the bootloader once and for good with the official way?
Because I've read that the unofficial way isn't so secure in long term.
Do I have to install from the Updater the latest Cina Dev ROM and after that to proceed with the official unlock? Or it is better to use the Fastboot ROM?
Please could some one tell me in any case what to do ?
Thanks !
If you don't flash something that will lock your BL, no need to Unlock.
Ok first I must check the status of the bootloader to be sure that it is unlocked (via cmd control or cpu-z)
And after that can I choose an unofficial weekly miui.eu international ROM and install it?
Can I download and also update every week via Updater this ROM without issues?
At the moment my problem with flashing is that I don't have my pc (the one I have now runs win xp) and I don't want to stuck with the eventually malware or fully spammed modified rom of the reseller..
Which options do I have?

TWRP works perfectly. The backup is simply stored in your internal storage。

How do I safely root and unlock bootloader on Marshmallow?

My device is European L04, currently running North Africa release (the earliest Marshmallow build uploaded) - L04_2016_0316_0900 (B820)
I'd like to unlock the bootloader and root my Honor 6. I've never done it (on this particular device), because I've read enough here to know it's slightly more risky than on other devices, especially when you plan to update the stock rom soon, so I preferred to wait until I have the last important update the device is likely to receive - Android 6.0.
What I want to know (some of the answers are in the topics which I listed below):
MultiTool - I've seen reports of bricks when using MultiTool with EMUI4/Marshmallow - why does it happen? My understanding is that MultiTool is a bundle of adb/fastboot and some recovery images for older Android versions, so my theory is that instead of using MultiTool, I should simply get the proper recovery for Marshmallow and flash it manually with fastboot, right?
unlocking bootloader, rooting, flashing recovery - I think I understand the process; in a nutshell: 'fastboot oem unlock X', 'fastboot flash recovery imagename.img', then flash the proper SU.zip in recovery. Where do I find the code, the Marshmallow recovery image, the SU.zip file?
will recovery backup in TWRP work without any problems?
what is the procedure to go back to stock completely after rooting? Unroot, (then wipe if it's needed?) so I am able to safely flash stock firmware again (since, from what I know, flashing stock on a rooted phone makes itself brick permanently, right? or is it just a soft-brick and it can be fixed?)
is there anything else I should know before proceeding?
What I found so far:
http://forum.xda-developers.com/showpost.php?p=66615082&postcount=502 - two recovery images, TWRP and another one (stock?) for the Marshmallow release
http://forum.xda-developers.com/honor-6/general/honor6-multi-tool-t2963060/page50 some rooting instructions for the L02 beta, see posts 494 and 498; no idea whether this is applicable to final Marshmallow or L04 at all
http://forum.xda-developers.com/honor-6/general/huawei-honor-6-plus-unlock-bootloader-id-t3357259 an app to get the unlock code, seems a bit shady to me though on the first glance
http://forum.xda-developers.com/honor-6/development/honor-6-rooting-method-t2962795 alternate methods for bootloader (through a website or by email), in case the app won't work; also, detailed instructions on unlocking and rooting
Basically, I need to know whether my procedure is more or less right before I proceed. I think the information is quite hard to find and the risks are quite high, so I'd like to make a promise - when I'm done rooting it and I know the correct process, I'm going to make a "Update to Marshmallow, unlock, root" how-to thread for all the people that will need it in the future.
Another two questions...
1. Where do I get proper SuperSU for Marshmallow? I get a boot loop (yeah, I know I have to wait and I did, but it's a pretty obvious bootloop from watching the logcat content, and nothing new happens...) after flashing http://download.chainfire.eu/supersu-stable (2.65).
2. I have unlocked my bootloader and installed TWRP, so recovery and fastboot are functional. I didn't make a backup before flashing the zip and now I'm in a bootloop. How do I restore working Marshmallow? I assume I can either beg somebody to upload a TWRP backup for my H60-L04, or somehow flash the stock over what I have now. Can I simply use manual update from SD? Can I somehow flash Marshmallow again with fastboot? I'm too scared of bricking my device right now so I guess I'll brace myself for a few days without a phone until somebody helps me :/
I just flashed the Marshmallow release I had before the bootloop (I used Huawei Update Extractor and flashed boot, cust, system and recovery with fastboot; then open up Huawei recovery and factory reset for good measure, I'm not sure it was even needed) and the device is working. I'll restore my stuff, install TWRP, make a backup then try out your ZIP. Thanks
edit: thanks again - your zip works indeed. So after the initial hurdles, now I've got working root and a reasonable way of restoring in case I screw something up along the way.
Before making a new topic with the tutorial I have a few more questions.
First of all, why exactly we weren't supposed to update the rooted devices? I'm not currently interested in OTAs (it's pretty obvious that it needs a functional Huawei recovery, and you need to unroot cause an update can make a mess in a rooted system, making it bootloop for example), but can we flash extracted images with fastboot on rooted devices? Logically, we should be able to... How about sdcard update method?
Can we flash Marshmallow on Kitkat? (fastboot, sdcard, local update methods?) Or do we need to update to Lollipop along the way?
Can I flash stock roms in general (evenbetween different Android versions) by using fastboot with {boot, cust, recovery, system} images only? There's a lot of images that you can extract with Huawei Update Extractor - why there's so many if they're not needed?

do i need to update the radio and bootloader?

I have a Verizon pixel that's been rooted from day one. I'm running the latest PureNexus ROM and had a question about whether or not I need to update the BL and radio. I've only flashed ROMs and never messed with anything else.
If I should, what's the easiest process??
I do. Do you have to, maybe not but I like to have the latest to match the latest OS.
You need to keep in mind that new bootloader complicates things a bit for root, TWRP, etc as it needs a signed boot image (there is a zip for that).
Radio is easy, just flash it in fastboot.
fastboot flash radio_a radioimagefile.img
you can do both your slots that way.
You can do same for bootloader same way but you may need to reflash your TWRP and SuperSU.
For now TWRP and superSU are not signed so everytime you flash them you need to flash VerifiedBootSinger right after.

TWRP Flashing Custom Roms Zip Files Error

Hello XDA Developers
I have been trying to flash a custom rom on my Google Pixel which is running Android Oreo and I have gotten as far as unlocking the bootloader and installing TWRP. How ever when I attempt to flash any zip file it just says error installing zip and I have no idea what's going on. TWRP sometimes even has trouble mounting the proper partitions so it's a bit of a hit and miss. Id really like to install a custom ROM. I thought maybe it was a bad zip file but I have tried several different ROMs and they all throw up the same error.
Update: Okay I have figured out that installing newer versions of TWRP doesn't work with some of the ROMs and it's better to use the older versions but you have to figure out which one that is if they don't tell you. I was able to successfully install a custom ROM.
Dunno if this advice is any good but don't set a pin code or password on the phone leave it unlocked it's easier for TWRP to read the partitions that way.

tmobile bypass twrp unlocked bootloader no service

I tried to follow these instructions: https://www.xda-developers.com/t-mobile-oneplus-7-pro-root-tutorial/
I first flashed the phone to the international firmware and then installed the devleoper preview which allowed me to unlock the bootloader.
I then updated the developer preview to a beta version of oxygen os 10 which made it possible for me to use the fastboot mode in order to load the twrp and then install it with sideload
I then tried a few custom roms such as havoc os.
Unfortunately at that point I get kind of stuck because there is no service, which is strange considering that the article claims that the service would become available during a custom rom install.
After flashing the phone back to the international firmware the service works again.
I am not exactly sure what I am doing wrong.
Basically the main issue has to do with the fact that there is no service as the developer preview trick starts and me not getting it back until I flash back the international firmware which has the bootloader locked and has no custom recovery.
The main reason why I wanted to do all of this is to simply have root.
The solution ended up consisting of reinstalling the stock oxygen os with the TWRP recovery AFTER the whole unlocking thing was finished, at which point it should either be possible to jailbreak the oxygen or to install a custom rom.
Either way the service seems to be back.
If you ever encounter such an issue it's possible that reflashing the stock os with TWRP may fix it.
