Hello ! I have a problem . It irritates me any photo software from LG and would like to upload CyanogenMod . The first thing I did was to install the drivers for fastboot according to this guide :
http://forum.xda-developers.com/showthread.php?t=2119090
But I think something went wrong because the point 14 something goes wrong and the phone will not restart and I do not know if everything went about Is it possible to make sure they do that? When instalwoałem drivers in device manager I did not have the device LG P2 , and most of the pictures / videos I see that the phone is in the name. I only had the OMAP 4430 .
Secondly, I installed rom v20b open eu . I waited 30 minutes and according to this guide http://forum.xda-developers.com/showthread.php?t=2221102 I wanted to unlock the bootloader . Unfortunately, only the phone restarts . I have a bootloader version LK MAY- 2012 but apparently it has nothing to matter.
Drivers have rather all installed so it's not the drivers fault . Can anyone had a similar problem with bootloader but somehow handled ?
P. S. Sorry for my english , but I used Google Translator
Hello,
A lot of people seems to have the same problem as you. It is not linked to the bootloader version (I also have the "LK MAY- 2012" version and my bootloader unlocking was a success).
According to this post, you need an active SIM card during the 30 minutes wait : https://plus.google.com/115049428938715274412/posts/CUu6YE3C6C2
Did you have an active SIM card when you tried it ?
There are references to "permanently locked bootloader" if something was done wrong : I hope for you it is not the case .
I hope too.
Yes, I was an active sim card for 30 minutes, if the word active, we understand that is inserted into the phone Do you think that doing this on Linux which is expected to make the difference? And you had any problems with unlocking or immediately did you do it?

Hello there, I have two Huawei Mate 2 (MT2-L03) and one of them is in a bootloop (I was trying to update to lollipop but forgot to unlock bootloader), the other one has Lollipop update and is working (but it has the screen all cracked, in some parts you can't read and speakers don't work). I tried searching in this forum on how to take it out of the bootloop and I didn't find any answers, now I can't get the bootloader unlock code from Huawei because they are asking for the phone ID and I can't access it with the phone like that.
My question is, is there a way to copy all storage from one phone to another or swap it? Because I thought that in that way I could fix the phone (the one in Bootloop). Remember they are both from the same model.
Hello friends of XDA, I have a big problem between hands, I have a MOTO Z and I had it in android 7.0 since last year the update to andorid 7.1.1 did not arrive and I felt that with android 7 the battery was consumed very quickly, so I tried to find the update to flash it and just about 3 days ago I found it, I proceeded to download it and flash it in fastboot and adb.
The thing is that a few months ago, browsing through my phone (I had already rotated it, and unlocked the bottloader, I decided to re-block the bootloader, and remove the root, which never worked at 100) I got into the developer options, and I saw an option that until then I didn't know about its "OEM Unlock"function, as it was turned on and deactivated because I thought it didn't work.
Returning to the update flashing I proceeded as usual, with the commands, I proceed to restart the device and show the image of the boot of motrola but then it shows me a message in red letters.
"Startup Failed"
"failed to pass validation, backup to fastboot.
I thought it was a compatibility problem with the downloaded version of 7.1.1 so again I decided to flash the stock rom 7.0 but when I finished and restart the same message appeared.
I started to investigate and it seems that the OEM blockade is responsible for not being able to install any Stock Rom, or anything, and now I have a nice brick with Moto mods and I can't use it.
I wanted to unlock OEM in fastboot but nothing. sends message from "ALLOW OEM UNLOCK IN SETTINGS"
There is way to unlock the OEM from pc or fastboot without needing to be unlocked from the android settings, as in my case it is impossible for me,
I'd be very grateful for your help friends, I know it's a bit tedious to read but it's the only phone I have and I feel weird without it on the street.:bueno::bueno::llorando:
I'm with same problem here!

Try to boot in Fastboot flash twrp and flash ressurection remix rom. It's great rom. Forget about locking. I had the same problem like you as I was trying to flash stock ROM and lock bootloader.
I gave up on this.

Well, when the root didn't work properly, I flashed the phone again and blocked the bootloader. Will I still be able to install TWPR or should I lose my phone?

What do you mean with "I blocked my bootloader"?
Twrp is easy to flash. Root is integrated in ressurection remix rom. And this rom is great. Just try to flash twrp in Fastboot and than ressurection remix with twrp.
Can you boot in Fastboot?
Do you remember what build of 7.1.1 you had on your device before downgrading to 7.0?
If so, I would suggest finding that firmware (the full stock firmware, not OTA updates) or newer if you can, and try to flash that. Since your bootloader is still likely from the 7.1.1 build, a locked bootloader will only permit files matching the same patch level (i.e. from the exact same stock ROM as that bootloader patch) to boot.
If not, then unfortunately there's not a lot we can do. You could wait for a newer firmware to get leaked, but as your device is unable to boot (due to failing the bootloader checks) and you cannot toggle OEM unlocking because you cannot boot, it's a nasty vicious circle that is difficult to get out of. You may have to consider sending your device for service and pay for an expensive motherboard replacement otherwise, since Motorola have a record of your device being unlocked. Your service centre experience may vary.
Only lock a bootloader after ensuring you've flashed all the stock firmware and it is all the same patch level as your bootloader. Hopefully you'll find newer firmware that you can repair with.

I solved it, I finally flashed the stock rom to my phone and it works.
Apparently my pc was not flashing the stock rom in adb, and the phone turned off when loading the software. I did it 3 times until I load correctly and start well.
if you have the same problem apparently then OEM Blocking is not responsible. You have to flash the most current rom or the one that you had by default when the brick happened to you, you flash it in a normal way with commands of adb and ready, I would have to come back to life.
download from firmware center MotoZ Griffin the most current rom stock at 7.1.1

Thanks for your help friend, I finally flashed it with a recent android 7.1.1 update. Apparently the OEM lockout was not the culprit, but it was an interrupted flash of android 7.1.1 at some point when loading the software to the phone, it would shut down on its own and not complete the installation, which showed me the mentioned message. I didn't realize that and thought it was the OEM blockade.
I finally did it on another pc and it worked. the phone came back to life.
I have one Moto Z2 Force (XT1789-05), bought from coolicool.com, I didn't know device came Unlocked Bootloader, Device rom had problem with many apps, I googled and found one topic in XDA developer to Install Stock Rom, I downloaded and Installed India Rom, it's worked somehow fine, but still had problem, I downloaded Verizon Rom, Android 8, after Installed Android 8 Verizon Rom, Locked device bootloader immediately, now device stuck at Welcome Wizard in Android 8, after select language I got this message: (Please wait, this may take a few minutes) this is proof video (http://ahmn.co/Upload/IMG_0161.MOV), after this issue, device already locked, I can't unlock, because need to go to the Developer Option in Setting, I stucked in Welcome Wizard, there isn't any bypass, So, I start to search in Google, XDA-Forum, Android Central and more, I created many threads, many requests, no one can't help me, I tried to reach google developer support to the tell to me how can I bypass Android 8 Welcome Wizard, there is must be a way, but I can't find it, now I can access to Android Recovery and Bootloader
1. if you help me to FORCE UNLOCK device without need Developer Option in setting my problem will solve
2. If you help me to Bypass Android Welcome Wizard, access setting and enable OEM Unlock
3. If you help me to update the device from Android 8 to Android 9 Verizon ROM via ADB Sideload or Update from SD card in Recovery mode
4. If you have any idea to how can I fix it
Extra Information: I bought Belkin and Uni USB-C to Ethernet Adaptor to help me bypass Android 8 Welcome Wizard, I bought WSKY WIFI Adaptor because device Wifi can't find any network (I found QR setup by tap several times in Language Selection), after this section need to download google device policy apk, my device can't find any Wifi Network and my Ethernet Adaptor can't help me either, So, I just remained with my phone, and I can't do anything,
Please, someone, help me

Hi, in september last year I bought New Moto z dual sim With 64 gb on Ebay.Co.uk. After one of official updates Phone starts reseting itself and stuck on informations that this device may not work properly, I have to restart bootloader to get Phone working. I tried to Connect to Verizon aplication on my Windows 10 pc but i have unlocked version and program doesnt recognize phone, so I sent to Lenovo official Phone fix Company but they Will not Fix my Phone because IMEI is from hong kong. So I dont have a warranty, any user noob frendly solutions??
Since you don't have your warranty anymore, you can unlock your bootloader and flash a custom rom.
Unlocking the bootloader, flashing TWRP and flashing a rom is pretty easy, I did it within 10 mins or so after placing a new motherboard.
If you can wait and want to know more, I can assemble a quick guide thread with all the fresh info this weekend.
Ok thanks, could you notify me when you will do your guide.

I sent my device do diffrent repair Centre but they told me that bootloader wont let Them install fresh system. What can i do maybe selling for parts.
hi!
after reading all related post in this forum and searching google for ages, i am still not able to unlock my z5c's bootloader. it is not a lack of skills or know-how - i have successfully unlocked my z1c and z3c - but this one simply does not unlock.
i have tried both windows and linux, used shell and flashtool, all drivers properly installed, phone is correctly recognized, bootloader unlock is positive, oem unlock and usb-debugging are activated, phone is in fastboot but i still end up with error "command did not succeed". flashtool additionally shows "oem unlock not activated?". it is, but doesn't seem to have any effect.
i also tried to include the .txt file with the unlockcode into flashtools filestructure: flashtool does something but can't finish the unlock proccess and my phone is not resetting.
i even tried those one-click unlocker without success.
and there is something fishy about this phone: three month ago i got it brandnew from a vendor in china via ebay and first thing i did was connecting it to the pc companion to upgrade the firmware which was 5.1 and it told me, firmware was up to date... so i tried the repair option and it told me "that due to it's prototype status it can only be upgraded from certain ips" - although the phone does not show any hints of being a prototype, neither software- nor hardwarewise and even if it was, it wouldn't prevent the bootloader from being unlocked (afaik).
so you guys are my last hope! any further ideas???
regards,
andi
Hmm... Possibly not the solution but have you tried enabling "Unknown Sources" as well?
Another thing is - you can try flashing a later version of the firmware with Flashtool - one that is common. Afaik there are some versions that have trouble unlocking. Try flashing something like Nordic Unbranded, boot it up, make the settings again.
P.S. Flashing does NOT remove the old leftover firmware - it just writes on top. So you should format the partitions (/system, /data, /cache, /dalvik-cache) before flashing in order to start clean.
when i couldn't upgrade the firmware via pc-companion i used flashtool to flash 7.1.1 (some german version) which i kept ever since. so flashing a different firmware before unlocking is something worth trying? i thought of this as well but never actually tried it because i was just too lazy going though all the setup process again if the attempt failed just like the others... but i'll give it a try then!
and thanks for the input!
Hy,
For me i had to make two steps :
- Flash a non-branded firmware from Xperifirm
- Network unlock it (actually for me it unlocked automatically at the end of the warranty ). This step it is critical (as i was informed in the Sony store)
Then the normal cmd command through adb worked fine.
Basically for me the network lock / warranty was the issue that prevented me to unlock the bootloader
thank you very much for your Input! but there is no network lock...
what i was going to do was flashing a different firmware and try again - and there is something else i didn't think of: the usb2 connector of my mainboard is blocked by an infrared device to power up my pc by voice command via alexa and a harmony hub. and to still be able to use the front usb ports of my case i connected them with an adapter cable to a free usb3 socket on the mainboard…
so it might have been the firmware, the usb2 port on a usb3 socket or prototype-status that caused the trouble - but i'll never know cause basically i'll give up on that phone since more issues occured… i contacted the vendor yesterday and it seems i'll get a full refund!
i now got my hands on a shiny new galaxy s7 and hopefully i'll experience the joys of oreo 8.1 and lineage 15.1 anywhere soon without the hazzle!
thanks again for your help and regards,
andi
Samsung A02s(SM-A025F)

1.I unlock oem through developer option
2.I unlock bootloader successfully
3.I downloaded firmware and patch AP with magisk to root
4.I flash Patched AP
5.After getting my phone rooted successfully I want to install TWRP Recovery
6.I downloaded unofficial version of TWRP from xdaforums....
7.I followed the steps guided here
The steps are as follows
1.reboot to boot loader and flash vbmeta_disable.tar
2.Put TWRP tar in AP and flash
3.Reboot to recovery
4.Disable encryption
Go to Advanced >Terminal : type "multidisabler"
5.Go back to wipe>Format Data>type "yes"
6.Reboot system
This is my first experience to root and flash TWRP.... but after that when I reboot my phone got lock .... only official binaries allowed to be installed....and stuck there
I got frightened so I locked my bootloader
But nothing happens...
I downloaded stock firmware and flash.....now my phone works perfectly But I want to root my phone I searched and found a correct way to root but now oem unlock option is not found in developer options....
I watched hundreds of videos on yt and searched a lot on Google but
found no proper solution.....someone tell me to wait 7 days....
In about phone> phone status>uptime
Uptime should be equal to 7days... then oem unlock option will appear but ...... I want another solution date change and WiFi connect is not solution ... If any body knows any other solution please guide me ... I'll be very thankful.....
@ladlabaloch512
Perhaps your device has the same "OEM unlock" block like mine.
On mine I was supposed to wait 7d after turning on dev options.
I bypassed that by
1. switching to airplane mode
2. Setting manually date back one month
3. Restart (still in airplane mode)
4. Turning off airplane mode and let it sync date
and voila OEM unlock option was there.
Perhaps that works on your device as well.

Keep us updated.. I'd like to get my OEM unlock to come out of hiding.. this is frustrsting.. i see all these tutorials for the A02s root, twrp and ROMs and whatnot and I'm itching to get flashing!
Is it possible to flash an unlocked carrier firmware in ODIN and then be able to unlock OEM? Without carrier issues or anything? I'm a little nervous to be the first to try.. and not sure where to find US unlocked carrier firmware or if location even matters... I have the SM-A025AZ (US Cricket variant).. I guess as long as Download Mode (fastboot) is still accessible I could just flash the Cricket version back to the device.. bricked my LG-E980 back in the day.. took me a few months how to get it back up and running with LG flash tool.. i just dont want to repeat that fiasco lol... so anybody got any updates on hacking this OEM (un)lock bs??? Or any idea on flashing some other variant to the device without interrupting carrier stuff??.. seems like alot just to get a damn virtual switch to turn on.. but damnit I need root access! Lol.. about to just exchange this phone for an actual rootable phone.. i disagree with charging for hotspot.. that should be illegal.. getting charged twice to use th same bs internet.. eff that.. i just want Rooooooot!!!
Hello,
I have also been having these troubles, with no way to unlock oem after stock flash, and the closest I've got to finding a solution was this, but I simply cannot find samsung's bootloader unlocking form like it says in the guide. I bought my phone just for a bootloader unlockable version (A025M), and now I am very angry at samsung.
also, since over a 1000 hours have gone by since last post, have any one of you solved this issue just by waiting?

its not only samsung that does this, many other companies like motorola does this. Dont be angry, just try a different device. Also, snapdragon US models (i dont think) arent able to be unlocked. If its a mediatek model and isnt sim/carrier locked, u can try MTKClient
