[Mate 8 General] e285:
Is there somehow I can RE-lock the bootloader, UN-root my mate 8 - L09 and reset everything like it was when it was new?

edit:

This is what I have done until now.

- flashed to stock recovery (phone is not rooted any more)

- factory reset

Then when I try to relock the the bootloader , I get message FAILED (remote: root type is risk)

fastboot oem relock ****************

...

FAILED (remote: root type is risk)

finished. total time: 0.970s

Someone know how to resolve this issue?

Could this be fixed by installing fresh and untouched complete firmware from huawei?

If yes, some know which link to use for my device and version?

Model number: HUAWEI NXT-L09

Buld number: NXT-L09C432B152

All help is highly apprechiated.

[One (M8) Q&A, Help & Troubleshooting] phoeniiiix:
Hello guys,

Months ago i bought an HTC One M8 on Aliexpress, it worked fine for a few days but suddently refused to detect my sd-card, so i managed to install a new rom (Android_Revolution_HD-One_M8_50.2_76b56b). Everything worked fine until a few days, when my phone was seemingly unrooted. So i decided to update to a newer version.

Then here we are, i downloaded dozens of roms but was unable to boot any rom i installed, im by far not an expert but i managed to use abd and fastboot to install twrp 3. I finally managed to install Cyanogen (cm-13.0-20151228-NIGHTLY-m8) but it didnt detecter either my SIM, IMEI and crashed all the time.

Now i'm running a nandroid backup with a Marshmallow Sense 7 rom i downloaded here: androidsage.com/2016/03/08/update-verizon-htc-one-m8-to-marshmallow-using-custom-files-ruu-ota using their firmware (m8MfirmwareTWRP3_0_0_1)

But it does not detect my sim card neither my IMEI

The phone is S-OFF with TWRP-3, supercid, modified MID (from 0P6B20000 to 0P6B10000) and Official HBOOT

[One (M8) Q&A, Help & Troubleshooting] redpoint73:
MID 0P6B20000 and product ID m8_wlv are for the Verizon version (supports CDMA, in addition to GSM, but we call it the "CDMA version" here).

You flashed a Euro firmware 1.54.401.5 and bricked the radio. This is a known result of trying to flash non-CDMA firmware to the Verizon or Sprint M8 variants, which should never have been done.

The damage may be permanent. The most you can do is change back to the Verizon MID, and flash Verizon RUU, and pray it fixes the radio issue. http://xdaforums.com/verizon-htc-one-m8/general/vzw-m8-master-ruu-firmware-collection-t2946473

If not, the radio is permanently bricked.
[One (M8) Q&A, Help & Troubleshooting] phoeniiiix:
Thanks for the awnser

I can still flash the radio, does that mean its not bricked ? (im not familiar with android internal filesystem)

In case the phone is bricked, is changing the main motherboard a good idea (50€ on ebay), i also eard of jtag unbrick services
[One (M8) Q&A, Help & Troubleshooting] phoeniiiix:
Back

:)

So as you recommended, i installed a verizon rom, and this time it actually show my IMEI in settings :good:, and i launched adb shell to change my MID

Now it seems to "detect" my sim card, it ask for it but says "no service" and does not ask for the pin, does that mean the phone is carrier locked (some boxes are greyed out when i try to add APNs) ? In case it is, how can i safely unlock it, i'm from France and my carrier is Orange
[One (M8) Q&A, Help & Troubleshooting] MeltdownSpectre:
You'll have to buy an Unlock code.

Also, the IMEI on your phone has been changed.

Verizon and Sprint IMEIs start with 99x, yours is starting with 35x to try and make it look like an international model.

Notice the meid still starts with 99, as the seller probably didn't bother or forgot to change it.

[One (M8) Q&A, Help & Troubleshooting] redpoint73:
Try not to use the term "ROM" interchangeably with "RUU", as doing so may add unnecessary confusion to the discussion. They are different things. The RUU re-images all partitions, something like 41 partitions. Of which, the ROM is just one.

The Verizon version is unlocked from the factory. So I'm suspicious whether a SIM unlock will actually work, or if its a function of the radio brick (improper firmware flash). I suppose trying to unlock is low risk, as long as you use a service that does not charge money if it doesn't work (as many of them have that policy).

I'm also not sure if a SIM unlock will work, if the IMEI has been hacked (as the previous user pointed out).

Either may be an option. But changing the motherboard yourself is not that easy, and I don't personally recommend it unless you are very experienced and comfortable doing such things. I've seen more than a few reports of such repairs go badly on this device. Its fairly common to break something else while trying to "fix" the mobo.

A paid mobo or JTAG may be a better option.

Thanks a lot, using the RUU update you provided (0P6BIMG) i was able to fix it, you saved my phone i'm so glad =)

What about fingerprint sensor, i am not satisfied as i wanted to.
[Xperia Z5 General] kylebeattie11:
Mine actually worked better in Lollipop rather than Marshmallow, it worked almost every single time I used it however since Marshmallow it does get a lot of misreads.
[Xperia Z5 General] ross23:
Good review. I would give similar scores. However, when I first got this phone with Lollipop i was having major issues, battery was horrible, overheating issues, and some other bugs were ruining my experience. When I got MM it seemed everything just magically fixed up (Although I later found out much of my battery woes were due to my Universities WiFi).

Now I have excellent battery life and I can easily get around 4 hrs SOT and sometimes 5+ hrs SOT with the battery lasting me on average 1.5-2 days. Further, I find no more overheating issues and even with extended usage the phone does gets warm, but never hot. Although I don't play graphic intensive games.

I am so happy with my Z5 atm. One of the best phones I have ever owned.

---------- Post added at 11:46 AM ---------- Previous post was at 11:44 AM ----------

I personally see no major difference in fingerprint reading between LL and MM. When I first upgraded to MM i did notice a slight increase in the speed and reliability, but after a few weeks, its pretty much is the same. usually its very quick and reliable, but there is that odd few occasions where it just doesn't recognize my finger.
[Xperia Z5 General] spaha-bih:
Yes, the same, after upgrading to MM, fingerprint unlocking was noticable fast, but after some time, like it just get worste.

Also the same for heating, my everything was fine at the begining, but after it just get warmer for some reason, and i am on last update.
[Windows Mobile Development and Hacking General] Ultimate Chicken:
I figured I should come to you guys after accidentially trashing my bluetooth whilst trying to fix my A2DP no output problem in an unofficial WM6 ROM build.

I just need to do a little research here. Are problems with stereo headset compatibility common, even in the latest builds of WM6 ROMs? Is there a registry setting I should be aware of, or a port number I can check?

Or, heck, a way to check if the drivers are actually running?

Max OD's TMobile S7 port had the best implementation of AOD I've used, but it was still buggy and annoying...i disabled it straight away. I don't think Samsung has even had it working all that well. Different strokes and all that, but I don't see much point in the feature, makes the phone feel like an LG clamshell from '04.

Backuping EFS partition will backup data like device specific essential information such as the IMEI (International Mobile Station Equipment Identity), wireless device MAC address, baseband version, product code, system ID and NV data.

If you lose your IMEI during flashing and wiping roms, you will end up with a piece of brick incapable of making calls:crying:

[Samsung Galaxy S7 Edge Questions and Answers] CuBz90:
Well, I've managed to fix it myself. I noticed the Serial coded into my phone was not matching what was on the back of the phone and the box. So my wife let me root her S7 Edge and get a backup of her EFS. I then used a Hex editor to change all the details to match my phone (such as Serial number and CSC) then I restored this in TWRP and reflashed stock firmware. This worked but the IMEI was just 000000000000000 so I could not make calls. So I flashed the Factory firmware and this restored the IMEI. So then I reflashed stock firmware again and was getting dm verity error. I am able to get into system and use it as normal if I flash TWRP then flash the no verity zip. I am currently working on fixing this error not but not a huge deal.

This is good news. I lost my IMEI as well on my 930F. I was actually able to restore the s/n and fix dm-verity by copying certain files from my original corrupted efs folder that I had backed up to my ext sd and using my galaxy s6 edge I compared permissions and fixed them accordingly. File by file. Took me a while but eventually that fixed my dm-verity issue that wouldn't let me boot after flashing stock firmwares. My IMEI is still stuck on 00000's though. The s/n is under efs>factoryapp>serial_no. Just open that up with root browswer and input the s/n from the back of the phone or your original box and save. The permission for that file should be rwxr-r-- or 0744....thats how I was able to restore the s/n. For drk and dm verity I pretty much made sure every file except the corrupted nv_data.bin file was copied from my corrupted efs folder and used my s6 to compare and fix the permissions where needed. There's a few files in my s7 that my s6 does not have so I just left those alone. So I know there are still a few errors in my newly generated efs folder. But I was able to restore those above mentioned things and was able to regain signal/baseband. If anyone has anything that could help us out please share. The few people with octoplus boxes around me said that the fix was not available yet. Oh and well the nearest person with octoplus box is about 120 mile drive for me. So if he tells me he cant do it, I aint going. Thats a long drive..haha
[Samsung Galaxy S7 Edge Questions and Answers] CuBz90:
I did that (by editing the Efs.img and restored it using an efs restore app) and have got my IMEI back but will still get the dm verity failed error when flashing firmware. I have to flash the no verity zip to bypass it.

Easy way to hide files without moving them to the internal storage's "private mode"

If you want to hide something, Samsung has included "private mode". Unfortunately, this puts everything on the internal storage....which might clog up quickly. If you just want to hide a picture or something (say your mom wants to see pics from a recent trip, but she probably doesn't wanna see your gf's tits), you can do it while keeping it on the SD card. First, put all the files you want hidden in a folder. You can do this by going to the "my files" stock app. Then finding your files, selecting them, and moving them wherever. Create a folder on the SD card. To hide that folder, simply rename it, putting a "." at the beginning. Now, it will be hidden from your gallery or whatever.

To unhide the content, go back to your files app, hit "show hidden files" and then rename it again, removing the "." from the beginning.

Enabling OEM unlock in Developer options stops this behavior. But, you have to get Android fully working first.
