Hi!
Yesterday followed AndroidRoot.mobi's guide how to backup the blobs and important files, it went successfully. But now I am stuck with the 4.13 bootloader and I want to update to 4.23. I've tried several methods without any results.
I've tried to flash an unmodified version of the 4.13, flash a factory image that comes with the 4.13 also been trying wugs toolkit. The error I get is "BadParameters".
Does anyone know what I should do to update the bootloader to 4.23?
Flash with fastboot, if it doesn't work then be sure to post all input/output from cmd/terminal here

I have tried to flash via fast boot, but it doesn't work. I will post a screenshot below.

So you have a working tablet, but want to update bootloader right? Do you have WiFi only n7? Can you check something else as well, run this
fastboot getvar all

Yep, the tablet works fine (Stock 5.1.1), but it annoys me that it seems to be impossible to update the bootloader.
Yes, it is an Wifi only 32GB.
Here is the output from fastboot getvar all
Edit
Doesn't it look a bit strange that the partition-size:bootloader is blank?
I also tried to flash the bootloader from an another computer and got the same result as above but I noticed that in the upper-left corner there is a text "signature match"
Yeah this is what I was afraid of, not a huge issue, especially as you have the backed up blobs from nv flash
I've seen this from time to time where device works and boots but there is an issue with bootloader partition, normally when this happens in another partition like /cache you would just reformat and be on your way but you don't want to reformat bootloader, its a risky thing to do
I would suggest to be safe and make a copy of those nv flash blobs and keep it all safe, if an issue arises you can use that back up
As for fixing completely I can't say for sure, possible restoring backup now will do it, but I can't say for sure
As of now I would just stick with what you have unless you are in dire need of lollipop

Okey, but do you have a link to a guide that shows how to reformat the bootloader partition? I don't use the nexus that much anyway, at the moment I see it as a fun project. I have the blobs in three different locations so they are my backup.
Btw, I got an nandroid backup, if that could help?
Nandroid won't have the bootloader backed up so no there, as for a guide to reformat the bootloader I doubt you will find one as typically this is a bad idea
You may be able to reformat and run e2fsck through adb like you would with other partitions but adb may not allow just as fastboot won't allow reformating this partition.
That would leave UART or JTAG which will require special a special cable and software, you can Google around a bit and see what's out there.
As for now I would just attempt to restore blobs and hope that does the trick
Best of luck!

you MUST reflash a kind of stock/not gps moddified version :/
Getting this same issue on wifes Nexus 4. Its stock with the 4.3 JB OTA no mods or root since that OTA. Can't understand why GPS.conf could be changed.
If I root and TWRP could a factory image update.zip with the -w wipe removed work to get her to KitKat without wiping and redoing her phone? I am used to flashing custom roms this stock ota stuff is giving me a headache.

You do not use custom rom or custom recovery to flash factory image. Use the links in my signature for instructions.

I understand that, she is stock ROM, with stock recovery and not rooted when she is having this issue. No root TWRP or custom rom involved. Since it wasn't working with stock recovery was looking for options without wiping device during factory image flash to fix GPS.conf file thats buggered.
She got the OTA normal way on her phone this afternoon, but it failed. Will check out your sig links when I get home and see if I can solve this without spending all night setting her phone back up from a factory image wipe :/ Thx for feedback and any pointers

The flashing will required an unlocked bootloader, so if its not unlocked you will lose all data when unlocking it. (Doing a factory reset in stock recovery also wipe everything.)
I don't really know what else you can do, if there were never any modifications, then the problem is due to Google having too much protections and issues for their OTA packages.
Unlocked so can do the method in your guide. But she says she wants to clean up her phone so a clean start will probably perform better and she gets the clean slate she wants, problem solved Though OTA checks annoy me now lol
thx for the feedback and guides
I flashed stock rom with Toolkit, many times wipe data - cache - factory reset - sd reset etc. But problem not solved. Tried 4.4.3 - 4.4.4 nothing boot system. Just stuck on bootloader animation or Updating system apps...
I can boot with 4.2.2. but just one time. After i reboot don't boot. Stuck on bootloader animation... If i do wipe, stuck at Starting System Apps.
Its something wrong with 4.4.3+ or baseband version idk. What can i do other than flash stock Google img?
Also sim card don't working... No imei no imei sv no baseband. 4.3+ don't boot. I really don't know what should i do.

Did you flash the corresponding modem too? May be your efs partition is broken...

Now flashed 4.2.2 (JDQ39) Google img with toolkit + TWRP 2.7.0.1 everything is Ok. Then flashed 0.48 Radio (Source: JDQ39). Nothing changed.
I also tried 0.84 radio.
And always boot takes a long time.
Maybe its hardware problem, how can fix it?

Try too when flashing 4.2.2 with toolkit changing your recovery to CWM. And it's not necessary to flash a radio after, the radio is included in the image.

If all else fails, take a look at this tutorial, in theory could recover access to your imei with it.

Hi all, well I think I have all but fubarred my 16gb shield tv. I unlocked bootloader, installed twrp and rooted, all was working fine. Then I decided to flash the full android rom that is on the forum . before doing so, i used twrp and made a backup. I installed the full android rom, although it seemed to work fine, i was not crazy about it and decided to go back to the original OS, so I booted up in twrp and went to the restore function, there were no backups to restore , I guess when I installed the system img for the full android it erased my backup somehow. anyway, moving right along, I next went to nvidia website and downloaded the restore image for the 16gb shield tv, i booted in to bootloader and was following the instructions to restore the shield. all seems to go fine until I try to flash the system img, then I get the error "invalid sparse file format at unknown block 0000" it tries to continue but fails, afterwards the system will not boot at all, I can get back to twrp recovery an flash the full android rom just fine, but am not able to flash back the original os without that error. any suggestions would be greatly appreciated, as I am stuck at this point as what to attempt next. thanks

Just going to go out on limb here, but are you sure the downloaded image isn't corrupted? You could try to download it again, if available do a MD5 hash check to verify it downloaded correctly and then retry flashing it.

Thanks for making such a great work! :good: I don't want to be rude, but some people are looking for a tool to completely replace NRT. Is there anything missing in your tool that we should be aware of? Anything we can not do but doable with NRT? Is it 100% compatible with Win10 and 8.1 factory images? Thanks!

For now all is working good, the only think you can't do with this tool is to root your phone, nrt tool use a modified boot.img to root it and for now i don't want to make the same
Hi Guys,
My son has a MI9T.
Hé wanted to flash a custom rom the day after he got this phone from me (why i dont know) but he never did it before. And i aM no expert either.
Hé installed a few custom kernals, and roms and TWRP'S and dont actually know what hé is dooing.
But the phone is stuck in startup screen with Every rom he installed so far.
Hé did no backups from the working device either........???
The phone have working TWRP now and unlocked bootloader.
i tried to do the Xiaomi recovery (Miflashtool) but wont work either cuz of the fault:
Anti Rollback protection and i cant find a right firmware for IT.
The anti rollback protection is on 1 on this phone.
Can Any one help me out maybe?
or is the phone already to throw away?
Hi. The anti-rollback protection exists purely in a file in the fastboot image. Here is a tutorial on how to avoid triggering it on our device:
https://telegra.ph/Fix-fastboot-flashing-problems-09-20
The reason that no roms he tried are booting is most likely that on this device he has to wipe data + internal storage after flashing or it will most likely not boot.

Download the latest fastboot rom for your device. Extract it and open the flash_all.bat file with Notepad++. Remove all the lines before "fastboot% erase.." line. Then run the bat file.

Move the fastboot rom folder (with the modified bat file) to C:/. Then try flashing again with miflashtool.
nothing worked for me. tried all the above and many other tricks but no.

OK! Let's try something different. First of all, the phone is not dead, so, don't worry. We just have to figure it out.
Enter TWRP, format DATA, tipe Yes (it's not wipe, it's format data).
Just to be sure, flash the latest TWRP https://dl.twrp.me/davinci/twrp-3.4.0-0-davinci.img
Since you formated data, you will have no files on your phone (be shure of that, if it isn't empty, you haven't formated data), you have to tranfer this TWRP from the computer or OTG.
After flashing TWRP, reboot to recovery. Now, let's flash some stable rom. Try this: https://sourceforge.net/projects/xi...K20MI9T_V12.0.4.0.QFJCNXM_v12-10.zip/download
Flash only the rom (no magisk, nothing). Reboot! Now, wait patiently. The first boot will take time (from 5 to 10 minutes).
Then, give us feedback. Ground your son until the weekend. Good luck, mate!
Hi
Do you find solutions???
used the above steps except edl mode and was able to sucessfully flash fastboot rom without crc list error
