[Q] LG GW62 brick?

Okay.. Help!
I just recently bought a LG GW620 from a friend.
Usually it runs on Android 1.5
I wanted it to run on Android 2.2
So, i searched the internet and found out that LG gives us this by default, all you have to do is download their update manager and let that run.
So i did.. Until it started telling me that i needed to reconnect the phone.
I did that.. about 5 maybe 6 times. After that, the update program stopped.
I now have, a big fat "!
EMERGENCY MODE" on my screen.
So, i searched, and came across a way that told me to disable the modem.
I did, but still the update program shizzle from LG doesn't seem able to find the phone.
I'm really inches away from going crazy, haven't had any food since 8 o'clock this morning(okay.. just noticed now that that is 12 hours ago.. should get some food)
But.. please.. help me!
Don't make me go back to my Xperia X1 with friggin' Windows Mobile 6.1!
Edit:
I tried this:

OK, got it.
In the settings menu, you can run a factory reset, and after a reboot, it's back to virgin state.
so, to recap:
1) You can recover from bricked state (IE, won't boot) by holding 1+Power on start to get in to Emergency Mode
- You will need LG-Utils
- You will need V10C_00.kdz
- You will need B2CAppSetup.exe (set language to English for ease of use)
- You will need USB modem drivers (I used USB SP modem drivers from LG Modem Driver 4.9.4
-- From LG-Utils directory, run KP500-Utils-EN.exe
-- Phone Model: GW620
-- File: \path\to\V10C_00.kdz
-- Version: V10C_00
-- Takes about 5 minutes and will reboot your unit to charging mode.
2) At this point, you must turn on your device. You won't have much luck doing anything because the GUI is gone, but ADB will continue to work.
- You will need Android SDK
- You will need to have previously set up USB Debugging
- You will need to have previously enabled root for adb
-- Launch adb shell
-- execute: am start -a android.intent.action.MAIN
-- this will prompt you with a GUI to select the app to launch. go in to the settings to issue a factory reset.
3) Voila. On reboot, you are on initial setup screen. You have lost all of your data, but have recovered your device.

But.. every time it wants to connect the phone, the phone randomly disconnects from my pc!
What am i doing wrong!? :\ is there a problem with my pc? Is the device completely fried?
Correction: The phone does not randomly disconnect! It only disconnects when i try to talk to it!

Bump.. anyone?

[Q] Padfone 2 bricked: invalid kernel

After a lot of reading on Xda and Modaco I am still not much further.
After rooting with Framaroot and installing TWRP through Goomanager I bricked my phone because I forgot to unlock the bootloader....
Is there any hope for this phone?
The phone cannot get into fastboot: power button + volume up.
Recovery menu (power button + volume down) is non-functional > I get the "invalid kernel" message again.
ADB and Fastboot and cmd in Windows are all very new to me but I have nothing to loose.
Thanks in advance for any advice.

"invalid kernel !!!" - I bricked my phone
Hello,
I have exactly the same problem... I've also red a lot without finding any suitable solution...
I rooted with Framaroot, installed TWRP and thats it - I bricked my phone (probably because I forgot to unlock the bootloader?)....
Same problem for me: the phone won't get into fastboot (Power+VolUp).
Recovery menu (Power+VolDown) doesn't work: I always get "invalid kernel !!!"

Hi Vakilando,
It seems we're on our own with this problem. Either no one has an answer or all knowledgeable people never had to deal with this problem.
We also choose a not-so-popular phone. The tablet-phone combi is too expensive and the tablet of mediocre specs.
I went for the too-good-to-be-true price for the phone-only... and after a lot of reading found out that quit a few people had problems with their phone.
Perhaps some code monkey (no disrespect) could tell me if we have more options when the phone is connected to a Linux system? Android is Linux based, so that would be a compatible pair. Windows can only see one partion on a flash card and, but I might be wrong, Windows cannot read EXT 3, 4 partitions.
Windows device manager does recognize the phone as "ASUS Android Bootloader Interface" so the phone is not completely non-responsive.
I also posted on a German site; Android-Hilfe where there's a dedicated forum with knowledgeable people so perhaps that gives more options.

do this!it will work!!!

Sorry, for not well-advanced users - could you please describe step-by step how to flash phone in "invalid kernel" condition CWM recovery with fastboot? Tnanks!

Ola Goldenval, try this link, it worked for me.

This is first link I found in google & tried to follow. My problem is that PC (W7 ultimate) doesn't see the phone. So cmd window is hanging on message "waiting for device" forever. Problem isn't in PC, as I tried different PC, where another similar phone had been seen some time ago.

Hi Goldenval,
the onlything I can tell you is that it didn't work out for me the first time, just like you now. Then I found another, German, website with lots of information on the subject and I gave it another try. Second time I succeeded...
it is a long time since it happened so I can't recall all the details but keep on trying and you will succed.

[Guide]Flashing HTC One M8 for Windows back to Windows Phone 8.1

*NOTE*THIS GUIDE WILL NOT LET YOU FLASH AN ANDROID HTC ONE M8 TO WINDOWS. THERE IS NO KNOWN WAY OF DOING THIS AS OF ME WRITING THIS COMMENT */NOTE*
I decided to make this guide because many non-tech/phone people will likely be trying out Windows 10 Mobile 10536 and will run into problems if they upgrade from a previous build, or eventually want to move to a new build.
Had a failure with Windows 10 Mobile? Had a botched update of some kind? As long as you can see the HTC boot screen when you power on your phone, you should be able to reflash your phone back to Windows Phone 8.1 and start over again!
The Windows Phone recovery tool (last I was aware) does not support the Verizon version of the HTC One M8 for Windows, so this method is the ONLY method for restoring the phone back to Windows Phone 8.1.
What you will need:
ACDU (the rom update utility)
Rom for your carrier:
Verizon(rom only)
AT&T(includes ACDU)
T-Mobile(includes ACDU)
USB cable (I recommend using original HTC cable to avoid problems)
Possibly USB drivers (if you don't have them when you get to the serial=>USB step, read later)
My handy reference video that is a bit old. I recommend watching this video at least ONCE before trying anything!
If you are able to, I recommend performing a backup of your phone before doing flashing any of these roms. Also, you should probably eject your SDcard just to be on the safe side. THIS WILL FACTORY RESET YOUR PHONE. It is my experience that a Windows 10 Mobile backup will restore on a Windows 8.1 Phone. If the phone uses any Authenticators, make sure you unattach those Authenticators from the accounts they are associated with before doing this!
Step 1: Extract ACDU to a folder.
Step 2: Extract your carrier's rom into the same folder as ACDU
Step 3: Make sure phone is NOT plugged into USB and 100% fully charged! Leave your data cable unplugged at this time!
Step 4: Shut down the phone. If the phone will not shut down because the metro screen will not appear or for for some other reason, ejecting the SIM card tray will normally force the phone to reboot. If that fails, then try holding the power button + vol down for several seconds and this will force the power off.
Step 5: With the phone off now hold both vol buttons, and then press power to power the phone. Keep holding both volume buttons down until you see a white screen with bar codes and your IMEI and other information on. This screen should read "serial" on the bottom (*note* NEVER post a picture of this screen anywhere without blacking out the barcodes and information!).
Step 6A: Plug in your phone to USB. If the prompt at the bottom changes from "serial" to "USB", then proceed to Step 7, otherwise check the Step 6B.
Step 6B: If did not change to the USB prompt, open your PC's device manager and see if you have an unknown device. If you do see an unknown device: Click on the Start button, then type: "Device installation settings." Change "Never install driver software from Windows Update" to "Install driver software from Windows Update if it is not found on my computer." The HTC driver should now download and install. Once you see the "USB" prompt on your phone, you are ready to continue. Change the driver setting back to its default if you have drivers you do not want Windows Update to upgrade.
Step 7: With the USB prompt now displayed, run "ROMUpdateUtility.exe" and select yes at the Admin privileges prompt.
Step 8: Sit back and watch the phone flash the ROM. Once the first phase of the flashing is done, you will see the HTC logo appear, and it will disappear and appear again. The phone should now proceed to boot into Windows Phone 8.1.
As far as the Verizon version of the rom goes, this rom is the shipping rom, so you will need to install all of the updates to have the newest version of Windows Phone 8.1. I recommend installing these updates before attaching a Microsoft account to the phone and restoring a backup. I recommend factory resetting the phone after installing all updates, THEN restoring your backup from your Microsoft account.
I hope this guide will help those avoid some of the pitfalls that comes with testing Windows 10 Mobile!

That is very strange. What carrier HTC One M8 where you attempting to flash? Normally that kind of error would indicate bad flash memory.

just use the wprt，so easy

The official Windows Phone recovery tool doesn't work for all carriers HTC One M8's, namely the Verizon one isn't covered.

I updated the Verizon ROM link with an active download link. Thanks arnoldcp for letting me know.

This must have been a recent change. The first time I tired using Windows 10 Mobile preview builds in March of 2015, the recovery tool did not support the Verizon model, leaving people who installed it completely screwed.

I'm a bit shocked that no one told me sooner about the bad Verizon rom download link (after 160+ people downloaded it). The file was corrupted somehow. I have changed it with a working file that should be okay now.

Windows Phone 10
Is there a ROM we can use to flash the phone to Windows 10 without having to go all the way back to 8.1 and in turn having to perform numerous updates to get into Windows Phone 10?

Not at this time. In reality, from original 8.1 on my phone, I only needed two small updates, then the large Windows 10 Update.
That could change with production Windows 10 Mobile. After that comes out, perhaps Microsoft will update the the recovery tools with Windows 10 Mobile roms?

Well, thanks for your help! I would have been lost without your guide as the Windows Device Recovery Tool was not working for my phone. I do hope the production build of Windows 10 Mobile comes out soon.
All the best,
JM

It appears that Windows 10 Mobile has finally launched. The HTC One M8 isn't on the current list of phones receiving official updates (HTC has said they will support updates for the HTC One M8 for a bit longer, so I have no doubt we'll see an official W10M update).
I don't see the phone as being ready for prime time on Windows 10 Mobile until after HTC issues software updates to the Dot View case software, and perhaps a firmware update to address wrong battery levels being reported. The old software doesn't seem to play well with the Alarms app (all alarms do not sound when a Dot View case is engaged!?), and Dot View is just about completely broken as well. Other then the show stopping Dot View issues, I think the software is ready for prime time. Last last major show stopping bug for the W10M builds in general, the keyboard not swiping in Edge, has been cleared.

So I did see the comment in the OP but just to clarify... does this mean I can not take my BL unlocked, rooted Verizon M8 and flash windows 8.1 or win 10 on it to try out? This is not possible ever?

Hi, good day. I'm investigating before i upgrade to w10 and i cant get my phone to work with the USB Drivers. I have followed all the steps and nothing. If i connect the phone to the PC, it does recognize it and does everything as it should with the data but i open HTC Suite it won't detect it. Also if i open wdrt the phone is shown there but if i click on it it sends me to boot loader mode (shows me the steps on how to get in)... I do everything as described there (comparing with your guide) and the serial thing is shown... But i connect the USB and nothing changes. Installed some drivers that ive found here and there but nothing changes. Don't know what to do next since i cant find more drivers... Thanks!

Is it also possible to flash an AT&T or T-Mobile rom onto a Verizon phone (if you root the phone; Verizon has probably locked the rom)? For Verizon has in the software locked out most of the european 4G bands, while AT&T and T-Mobile just let them open.
I'll be using my phone on the European networks, so it's nice if 4G actually works.

[Tutorial] FNF Ifive Mini 4s bootloop fix

So you probably did something wrong trying to get a custom recovery or root on your FNF Ifive Mini 4s. Well I did too, that's why I'm writing this
WARNING: This will remove ALL files from your tablet.
Just follow these steps and your tablet should be back on track soon!
So first you have to download FNF Ifive's official upgrade tool which can be found here
Press on the latest one, which as of April 2 is called ifive_mini_4S_US_1.0.6_20170330 Upgrade Tool&Firmware.
Now download both files in the onedrive folder. One is the recovery tool and the other is the latest firmware.
Extract both to a folder of your choosing.
Enter the folder called Driver and run Driverinstall.exe as admin.
Press uninstall driver, press ok and press install driver.
Go back to the main folder and run FactoryTool.exe as admin.
Turn off your tablet.
Enter loadermode on your tablet by connecting it to your computer with the included cable and pressing the powerbutton and Vol-.
Click on "Firmware" in the FactoryTool.
Locate the .img file you downloaded and extracted.
Check the box called "Restore".
Click on "Run" and wait for it to say success.
After it says success you should disconnect the tablet from your computer and just wait for it to boot. This will take a few minutes.
Success! You have now fixed your bootloop and updated to the latest firmware if you did not have it already!
If you had any problems I will be happy to help you

Error
Thanks for your help.
I tried it but it never end with "success". It says: "Wait for loader fail".
I don't know what I don't have to do.

That is probably because you are doing something wrong when entering loadermode or because you forgot to first uninstall the driver and then install it. When entering loadermode you must make sure the tablet is connected to the pc with the application open and running. Then you turn it off, and enter loadermode by pressing the power button and volume down simultaneously.
Hope this helps

Worked!!
Many thanks.
I manage to get the tablet working. I tried many times and I finally get it to work.
Sry for my bad English.

By using this tutorial.

Hi,
I successfully upgraded the firmware, it says Build Number ifive_mini_4S_1.0.8-W in my settings but my device still doesn't work properly. The message "Unfortunately Google Play Store/services has stopped" pops up frequently and the boot screen sometimes shows up out off nowhere closing all my apps and locking the device. I also can't open the Play Store at all. I always get the "Unfortunately Google Play Store has stopped" message.
Once I rebooted the device I got a bootloop but it stopped after a while and now my Wi-Fi does not work anymore. I can turn it on but it doesn't find any networks and turns itself off after a few seconds.
I read that some models are just straight up broken. The serial number of my device is P1QRMW1HAR. I bought it a year ago or so and I had problems with bootloops all the time so I barely used the device and hoped for a firmware upgrade that would fix everything. Now my patience is about to run out and I really hope that someone knows how to fix this stupid China device...

Hey guys!
i'm a bloody noob.
i never did something like unbricking my phone or wiping it or flashing it. It was my first time doing something like this because i just hate stock roms nowadays.
to unlocking the bootloader on my phone was no problem. but the problem was, that i updated my phone to adroid 11 and all the files i found in the past (half year ago) was for android 10, i think.
BUT I DIDN'T KNEW THAT BEFORE! I didn't knew that it would cause problems or that i had to be cautions about that.
Whatever. I tried to follow the instructions on this site: https://wiki.lineageos.org/devices/guacamole/upgrade
the twrp site i used was: https://eu.dl.twrp.me/guacamole/
Is the data "https://eu.dl.twrp.me/guacamole/twrp-3.6.0_11-0-guacamole.img.html" from 2021-11-22 know for adroid 11?
Because half year ago, i think, this all didn't work because there was no twrp for adroid 11 outside.
to be honest i don't know if i tried to install something else too in the past. i don't remember anymore.
I stuck half year ago on this bootloop problem. and i didn't worked again on this phone. i thought i could just wait for a new data for android 11 and try it later again.
Later is today but i made i worse!
I downloaded from this site https://download.lineageos.org/guacamole the file:
lineage-18.1-20220227-recovery-guacamole.img
after the command 'fastboot flash boot xxx.img' i reboot my phone.
Now my phone is displaying :
qualcomm crashdump mode
dm-verity device corrupted force dump
kernel-restart
what can i do now?
If i press the sound buttons + off-button i come the the boot screen which says:
blablabla
internetsite
press power button to pause boot
but this display won't stay long enough. after few seconds it's again on this crashdump mode
edit: i think i wiped in the past the whole os. And now? What should i do?
On this MSM Tool my phone isn't recognized. even with newest driver or other cable.
What should i do know? Is my phone lost now?
If some can help me please write exactly down what i should click / download etc.
If someone can german here and knows help, please help me in german. but don't have to. i'm glad if anyone can help me.

From what I can gather from your details I would try to get the MSM tool to work, it sounds like a driver issue, just make sure you uninstall previous driver first then go here
https://www.getdroidtips.com/download-qualcomm-qdloader-hs-usb-driver/
and get latest driver , follow all instructions,, also make sure your PC is installing all the optional drivers in the windows update section while your phone is connected to the PC, hth,, good luck
