You can request the unlock permission, then use the mi unlock tool with the phone on fastboot mode. After that flash the fastboot rom (8.1.4 because the 8.2.6 has many bugs). But I think your problem is going to be a hardware problem and you will have to finally take it to the technical service.

Energy Rom Problem

For the past few months I've been flashing separate Energy Roms onto my tilt 2. I finally found one that I liked and stuck with it for the past few weeks, which was the Dinik Glass Energy rom.
Everything was running great until last night when I was watching a video on You tube and everything froze up. I pulled the battery out and turned the phone back on and now it keeps going to the boot loader screen....
I've tried re flashing different roms to see if that would work but I've gotten nothing out of it.
If anyone could let me know of anything that i could possibly do to try and fix this I would be highly appreciative of it.
I dont know what may have caused the problem but in your situation i would have tried to do task29, flash radio and then flash a new ROM. this is normally how i flash my roms but task29 may remove somethin that may be causing the problem. if you have already done so, sorry for wasting 5 secs of your life ... let me know if it worked
Can you show me where I can dl task 29 at?
I had the same thing happen to my tilt2 last week!
Use task 29,
dont freak out when it only shows the screen that says touch pro 2.
Enter into bootloader and run ruu from there, it will fix everything.
Dont flash with sd card in or it will happen again.
I had to clear my sd card and reload it! good luck.
one more thing after task 29 do not disconnect from usb until you load next rom, that is what worked for me best.
hope it helps
I used the RUU and i tried reloading the ROM but it still starts in boot loader screen every time.
Should I just hit the hard reset?
you have nothing to loose by a hard reset at this point ... IF that works.
If I hard reset it will I have to flash a hard spl again?
Ok i noticed that yoy are pritty confused about the terminolog, so here is some help:
1. Task 29 - delets your rom of the phone so your phone become practicly unuseble.
2. HardSpl - "Unocks" (allowes) the phone for flashing custom made roms - i.e. all roms and ro preform Task 29.
3. Hard rest - reinstalls allready flashed rom.
4. Soft reset restart the phone - on/of
5. BOOTLOADER - allowes you to flash without activesync and from Sd card.
When any problem turns on with phene i usually check to see if there is any connection running. I discovered that too much internet over phone makes a phone buggy dissregarding the rom.
You dont have to hardspl phone again, once you did is enough.
Okay well here is the problem then... every time I turn the phone on it goes straight to bootloader. The only button I press to turn the phone on is the main power button. I've ran the custom RUU twice now. I've tried flashing a new rom onto the phone via sd card but it still turns on in bootloader mode. I'm nearly freaking out now because I'm led to believe I've got a bricked piece of $hit.
I hate sounding like a noob but if there is some way someone could run a step by step process to me that works I might through some $$ via pay pal.

I had the same problem with a phone about a month ago. I was able to flash the stock rom and it would boot up then put on the stock SPL and relock the phone. Sometimes I was able to take the battery out and get it to boot but even with the stock ROM I was getting the bootloader at startup. So once I reloaded the stock ROM and relocked it, I returned it and got a replacement.
Sorry, nothing I did every resolved the problem.
good luck.
I agree with taking everything back to stock
flash stock rom
do a spl relock
and start over...
oh, and dont forget about radios! idk if that could be part of the problem tho
I never changed the radio's so I should be good to go then, just the stock rom?
Try this :
- Enter bootloader
- Connect USB cable so "serial" in the bootloader changed to "USB"
- Perform Task29
- Reset
- If the phone enters bootloader skip this step. If not, hold volume down key while resetting (push the reset switch with stylus). The phone will enter bootloader.
- Flash a stock ROM. Download it from HTC website if you don't have one.
- Reboot.
Ow, the stock ROM also contains Radio. So Flashing with stock ROM will flash your radio also.

When you returned your phone and got a replacement was your phone starting in boot loader?
If so how did the workers at the ATT store react to that so I know what to expect?

How would you recommend that I flash the stock ROM back on?
I'm kind of confused because I've always flashed with my SD card, how do I do it through my USB? Could you give me a step by step?
Well, those steps I wrote are basically "step-by-step how to flash from usb".
Allow me to clear it:
- Enter bootloader -> Hold volume down button while pushing the reset switch
- Connect USB cable to your computer. and wait until the "serial" word in the bootloader changed to "USB"
- Perform Task29, download task29 and unzip it. run ROMUpdateUtility.exe. Follow the instruction.
- Reset/reboot. well, the phone will reboot itself after task29 is completed
- If the phone enters bootloader skip this step. If not, hold volume down key while resetting (push the reset switch with stylus). The phone will enter bootloader. Connect the usb cable again to your computer (if you disconnect it.) and wait until the word "serial" changed to "usb" again.
- Flash a stock ROM. Download it from HTC website if you don't have one. Just run the exe file you downloaded and follow the wizard.
- Reboot.
I reccomend you to flash with stock ROM because Stock ROMs are "Guaranteed to work(at least by HTC )" and contains radio that may be the cause of your problem. there's no need to flash to stock SPL, yet.
I was stuck in bootloader...
You can find task 29 here. I always do this before flashing.
After task 29, make sure USB is still plugged in and enter bootloader by holding Volume Down key while hitting the reset button. You should see USB on the bottom of the bootloader screen.
Now you should be able to flash the NRG ROM by running the RUU in the same folder as your ROM (rhodium.nbh file).
If this doesn't help, search the entire forum for "stuck in bootloader." I did this and it saved me the hassle of the warranty process.

I was able to get it to boot to the ROM by removing the battery several times and reinserting, powering on until it boot. I am on TMobile and called them and they sent me a new phone and returned the old through the mail after expalining the problem. So never went into the store.
good luck.

Note stuck in OTA mode - Upgrading from 4.0.4 to JB

Hello everyone,
I seem to have a problem upgrading my GT-N7000 to JB, the phone downloaded a 494MB update, and restarted to FOTA mode.
The progress bar went from 0-100% in about 15-20mins, but the phone has since then not completed the FOTA.
If I restart the phone by long-pressing power key, the FOTA restarts, but again gets stuck at the 100% mark. Pressing Vol Keys and powering on makes no difference.
Further the phone isn't recognised in Windows - says 'Device Malfunction'. The cable is fine, as it works with another phone.
My bad luck it was, the phone data isn't backed up - I never expected anything to go wrong. Is there a remote possibility of data recovery before I wipe the phone?
Now, how do I get back access to my phone, and how do I complete the upgrade, or reset the phone? I would be grateful if you help me or guide me how to proceed. Taking it to the service point would be the last resort, I want to try out everything I can before I send this in - it's out of warranty.
Regards
Abhishek

Dont worry. In general your personnel data are stored in internal SD and external SD, not disturbed by a system install process.
In that situation you'd better to install a new JB4.1.2 ROM using Odin in download mode.
Firstly see what ROM to be flashed. Official stock ROM, custom ROM, download it.
Read how to use Odin in download mode by connection USB PC-phone.
Odin is utility under PC. Download mode on the phone is entered after hold in the same time volume-down, home and power.

[Q] Unroot and Reset without Screen? Pls help

Hi,
ma phone ist broken: the whole screen is just white and has stripes of dead pixels across it:crying:
I would like to reset the whole phone to factory settings, as well as remove all apps and the root access, so I can send it back to LG an try to claim warranty.
I have not found anything on how to unroot the phone.
I can propably reset via the Boot menu (pressing down power button and volume down when booting). But then i still need to know how many times i have to press the down button to select reset, since i can not see anything on the screen.
Any suggestion on how to unroot?
My Phone does have the original LG Rom, however it is rooted an i removed some of the original Apps.
Will they come back to the phone when i do a factory reset?
Or will I have to flash the whole phone again with some stock Rom in these forums?
If i do flash, will these also remove root?
Thanks for any answeres!

No i have the problem, that i am not able to see where to change the connection type when plugged in to the pc.
could you send me a creen shot of the screen, where you choose the connection-type?
I know i can get there by tapping on the notification bar when it is plugged in.
Or do you have an better idea how to resolve this?
Edit:
I have managed to change the connection settings by just tapping on the blind screen.
The LG Support Tool, which I got from the LG Website, tells me that my device is on the newest software, therefore I can not do an upgrade.
How do I solve this.
Secondly, on behalf of the first answere: How do I know if I unlocked the bootloader? I installed CWM, does that mean the bootloader is unlocked?
Thirdly, assume I somehow get to reset the phone and change everything back to factory settings and Apps, how do I know it worked without looking at the screen?
Man this thing is really tricky.

You can force an upgrade using the LGmobile Support Tool. This can be found under options>update recovery in the upper right corner. I suggest you put your phone into s/w update mode before doing this though. To do this, hold the VOLUME DOWN button while plugging in the USB cable and keep holding it until you 'see' the s/w screen (not sure if this is an option for you, haha. Just make sure you hold the V- button for a bunch of seconds). As always, make sure you have all the drivers.

Usually the answer is if you don't know if you onlocked it, you didn't unlock it. But you need to have an unlocked bootloader in order to get CWM, so I guess you do have it unlocked. You can check in the secret menu. I believe the bootloader status is also shown in the upper left corner while in s/w update mode. But since your screen is dead, it's kinda hard to check.

Not sure if that's possible for you.. Perhaps someone else knows a solution for that..
Flashing the kdz will automatically format your system and data partitions
In case you aren't sure from adb shell you can run format system and format data commands or you can use fastboot erase <partition>
Always from adb you can enter the shell and use ls command to list contents of the phon and check if it was wiped

Phone do not boot after Oreo update

As i installed update and clicked reboot to apply it, now my system do not boot. Phone always stuck on white NOKIA logo boot screen forever. I tried few times to restart it via VOL-UP + POWER, but it always have same result - never boots. Please give me advice how to deal with it
It happened to me too, in December already. Mobile is in service now.
They flashed original fw, tested and returned it with results no fault. Right after switch on and new Oreo update it starts to freeze and produce various mistakes again, so I have returned phone to service. Will complain with seller about exchange.

That really sucks. But what do you mean by various mistakes? Like your system boots, but some functionality is not working? As i said in my case it totally cannot boot and recovery mode i can't enter factory recovery mode by VOLUME UP + POWER on start.

Ach yes, sorry. First it stucked in logo Nokia and rebooting again... VolumeUp+Power does not work normally on Nokia.
It helped procedure found here:
https://forum.xda-developers.com/showpost.php?p=74406267&postcount=34
Then I was able to make factory reset and mobile booted, but worked with various faults.
Did you unlock your bootloader , flashed TWRP and then changed the slot? Slot A to B or vice versa?
If so, then the solution is
How to solve!
I simply waited until the battery ran out
When battery was completely dead and no Nokia-logo appear any more >>
Then I charged the battery 3% juice without booting
and from there I entered recovery-mode with the help of a USB cable.
Holding the volume+ button while connecting the USB-cable
From TWRP-recovery I changed to the other inactive slot
and whooala, that's it!
Edit: I sucked the juice (mAh electric-capasity) out of the battery quicker with help of OTG-cable and an external USB-powerd fan.
Use almost any external max 5volt USB-powered devices available at home, even charging another phone unless the second phone doesn't reverse-charge, this Nokia can be used as a power-bank.

Huawei Mate 20 Lite stays black and ob pc it Shows "USB SER"

Hi,
So I had a Problem that my huawei (Working Phone) soft bricked himself over night. It was on his charger over night and worked fine on this evening... on the next morning I want to check my calender and the phone was already on the huawei logo... I think ok it does a reboot and locked himself. Than I forced off the device with power + volume up. Reboot instant after that and still stucked so ok I am soft bricked now. After searching a bit on Google it sad delete your cache via recovery. Problem I can't enter recovery or eRecovery only fastboot is available. Going into fastboot try the hisuit from huawei with the result phone not supported. But after that try on the white fastboot screen stand's "entering recovery mode..." so i let it do his thing... After many hours I came back and there it was the emui recovery. I decided to only clear the cache and boot. Again soft lock on logo... After that I tried again fastboot -> hisuit that doesn't work that the phone says entering recovery mode... -> but nothing happened...
I came back after the next work day...
The screen was black and I can't boot it anymore (still lie on my desk since first soft brick so yeah I am 100% proof the display will work) I plugged it in in my pc and it says now USB SER typical driver not found error code from windows...
IT will react when I force it with power + volume up only with dc from pc and reconnect in USB SER
Anyone any ideas to fix this hard brick?
Model: SNE-LX1
FRP and Phone locked
Stock Rom on it !
And If it possible I will let it as stock as possible (as I said it's only a work phone!)
Thanks for all the help !

Huawei phones just aren't what they used to be... Some time ago their unlock policy vanished into thin air, then came alligations of spying, a trade ban in the US, and I've even heard rumors about them trying to make phones brick themselves after installing custom software. ?
Sadly, I can only recommend to stay clear of their devices until this whole situation improves...
I actually have the same issue, my phone downloaded the latest update and I scheduled it to auto update at midnight,next morning when I woke up,was surprised coz my regular alarm (from phone) didnt woke me up,so I grab my phone and saw it was dead,but it was full charge, then it didnt open anymore,and I tried to do all the reset or hard recovery technics on the net but it still is bricked. If I plug it on a computer it only says usb ser.. I guess its how the company makes money by destroying their own system,so you'd buy a new one,coz you cant access your data or all your files from the old one,so you would buy a new huawei again,to retrieve your files.
USB SER is testpoint mode. Idk how, but you have closed the service mode contacts. In general, this is solvable, in the service it should not cost a lot of money.
