I have a device with Android 4.2.2 much crapware that comes with the phone company and being a minimum device I think first to make a root but now I'm thinking that best change the ROM, you recommend? I worry about the baseband version.

Thanks for your comments :fingers-crossed:

[One (M8) Q&A, Help & Troubleshooting] Rezhwscene:
Hi everyone,

So my HTC one M8 was rooted with TWRP recovery. It was running Android 5.0 I think. I got an OTA update but I was not able to update it because of TWRP. I wanted the update so bad and I searched on Youtube to know how to update the software. I found a video and I followed these steps.

1 - Replace custom recovery with stock recovery

2 - Process OTA Update

3 - Replace stock recovery with custom recovery

However, when I replaced the custom recovery with the stock recovery, I downloaded the OTA update and updated it. But after the update completed, the device never booted up. It shows the HTC logo then it goes black! (The screen is still on, but black!) Have I bricked the phone? How Can I fix it please!

PS. Here is the video I watched www.youtube.com/watch?v=PPPT5J8xG6w
[One (M8) Q&A, Help & Troubleshooting] Einwod:
That video is nonsense. There is a blatant mistake at 6.44 and the knob doesn't see it. You need to go back to stock first, then take the OTA.
[One (M8) Q&A, Help & Troubleshooting] Rezhwscene:
Thanks for the reply! But please, how can I fix my device now? I don't have TWRP anymore! But I can access the Stock revovery. What should I do? :'(
[One (M8) Q&A, Help & Troubleshooting] Einwod:
Go into fastboot and open a command prompt. Type in fastboot getvar all and post the output here. Remove your serial and IMEI numbers before you post. Hopefully we can get you back to stock.
[One (M8) Q&A, Help & Troubleshooting] Rezhwscene:
Okay, before I see your respond I did a stupid thing! I flashed TWRP and I wanted to flash stock ROM and I followed these instructions from this website

http://www.carbontesla.com/2015/01/htc-one-m8-4-16-401-10-stock-lollipop-ruu-0p6bimg/

But when I want to flash the rom its says "target reported max download size of 1826414592 bytes error: cannot load 'L50RUU.zip'"

Anyway, now my device is " Relocked" and when I type fastboot getvar I get this>>>> [IMG="CMD adb"]http://i.imgur.com/gPgiwz3.png[/IMG]

What should I do? :(
[One (M8) Q&A, Help & Troubleshooting] Einwod:
First unlock the bootloader again. TWRP you need and the command is: fastboot getvar all Check your messages also.

[One (M8) Q&A, Help & Troubleshooting] Einwod:
Luckily you have a WWE device. Download this RUU and run it from Windows. Make sure you have HTC drivers installed. The easy way to do that is to install HTC Sync and then uninstall it. The HTC drivers will be left behind. That will take you to stock 4.16.401.10. You will then receive the update to 13.
[One (M8) Q&A, Help & Troubleshooting] Rezhwscene:
I owe you my life man! Thanks for responding quickly. Anyway, Should I unlock the bootloader then run the .exe file?
[One (M8) Q&A, Help & Troubleshooting] Einwod:
No, the bootloader needs to be relocked/locked for the RUU.exe to work. It should work from fastboot mode. If it doesn't, I'll be on again tomorrow.

Not working on s-on ...

It will be great if you made it working on s-on phones too.
[HTC Desire Eye] fabrizio b92:
thank you for your works :D

What's the differente between this and the 2.8.7.1 posted new stock ui??
[HTC Desire Eye] xXminiWHOOPERxX:
Take the plunge to s-off. I do all my work s-off so.. figuring out what causes your phone to not boot it means I have to go back s-on.. which I won't.. sorry. Plus I'll be releasing a few new things that require s-off to do... sorry again.

2.8.7.1 and the other recoveries in that thread are all ported from m8.... this one is purely built for our device.. I will be trying to get it to become official.
[HTC Desire Eye] karo222:
There is no way to s-off desire eye like m8 or m7 phones and we can't s-off our phone here like other places.

Can we s-off eye with sunshine 3 ?? It cost 25$ :(

I'm not sure why it shouldn't work on s-on phones. I am s-off, but i have flashed custom recoveries on s-on HTC phones for ages.

I would appreciate it if someone could explains what the issue is?
[HTC Desire Eye] karo222:
No, It's not.
[HTC Desire Eye] xXminiWHOOPERxX:
How you on marshmallow firmware when it's not even released by HTC yet?

I honestly don't know what's causing it as I haven't once had this trouble on HTC devices... but I have an assumption.

On my E8 I couldn't flash anything above 2.8.7.0 when it was on kitkat firmware, so when I flashed 3.0.0-0 it would just keep saying entering recovery.... so I flashed Lollipop firmware via fastboot and then flashed 3.0.0-0 again it would finally enter the new recovery.

So my only conclusion is that some users are on kitkat firmware... at which they need to update the device... and since theirs a few variants they have to figure that out on their own.
[HTC Desire Eye] karanm18:
i had stock non rooted till android 5.0.2 and then i rooted it and S-OFF and installed android 6.0 (your port if M8) so i am not sure which firmware should i say i am on but i am not even able to update to 2.8.7.0 when i do i get the same entering recovery message but it never goes thru
[HTC Desire Eye] marsb455:
This is odd, because I have it install on my HTC Desire Eye, S-On and it functions perfectly. I have used it to flash back and forth all the new ROM that have just been released
[HTC Desire Eye] xXminiWHOOPERxX:
EYE_U, EYE_UL? EYE_UL_CA?

I would need to know how to find that out, but TWRP is installed and is working correctly. Thank You

Questions :P

oki i am noob to all this yet i have my S-ON desire EYEUL PVT lollipop on 5.0.2 beatsmod rom and its annoying and making my phone laggy. Recovery that im currently on is TWPR 2.8.4.0

Even kernel is flashed with Charms Eye cuz the one with the rom(Linux 3.4.x) wasnt working for me.

so miniwhooper i need ur help. I wanna have your [Android 6.0] SkyDragon EYE rom on my HTC.

can u tell me the process or atleast tell me if i have the right idea okay?

I tried flashing ur rom through TWRP 2.8.4.0. My phone got stuck in a bootloop.

now see i figured i should put this recovery TWRP 3.0.0.0 and then try to flash ur rom again.

so i wanna ask is ur rom ([Android 6.0] SkyDragon EYE) also a port from m8? is it flashable with 3.0.0.0??

is my process correct that i try to flash this recovery then try to flash ur rom?

Tell me what to do to get ur rom? do i need to flash something else too? like other kernel?

do i need to do flashing through windroid?? if in case this recovery doesnt work i can go back to 2.8.4.0 right? by flashing it through fast boot right? plz tell me everything im sorry im noob.

btw is skydragon better or viperm8 port? what do u suggest? anyways does flashing this recovery enable me to get ur skydragon rom working? im very eager on that i want it. plz tell me a way. My device is unlocked international version EYEUL PVT maybe its europe not sure. tell me how to get ur rom.
[HTC Desire Eye] karanm18:
I did flash the original boot.img of lollipop 5.0.2 stock and went back to stock and even got super cid and have s-off but still when i flash this it says entering recovery and stuck there.... please help there is no point of gaining s-off and unlocking without twrp my htc desire eye is EYE_TUHL
[HTC Desire Eye] xXminiWHOOPERxX:
Just flashing boot.img of stock lollipop doesn't mean you've updated your firmware.... you have go actually flash a firmware.zip in fastboot RUU mode. ??

Go to boodloader and give me the output to this command via pm

fastboot gervar all
[HTC Desire Eye] karanm18:

You have to update your firmware first to lollipop by finding the correct firmware file for your device and then install this recovery and through that you can install any roms and its the only way to do that as the recovery you have right now is not compatible with Marshmallow roms... Do all this with fastboot and you will be through all your problems in no time

[HTC Desire Eye] TahirZX:
What do u mean by update firmware to lollipop. I'm already on a lollipop 5.0.2 and it pretty much matches the stock lollipop Rom. So my question being that that I want skydragon marshmallow 6.0 rom on my phone so what are the steps as I tried installing it through twrp 2.8.4.0 it would install but would get stuck at boot. Now depending on what I have said so far what do I need to do to get that rom? Just simply flash this recovery? Through fastboot? Will it work? I have HTC desire eye EYEUL PVT. it's the Europe version. Is this recovery compatible with this model?
[HTC Desire Eye] karanm18:
You need to update your twrp to latest and after that you can get Skydragon Rom... But i would suggest you to get S-OFF for stability of your device
[HTC Desire Eye] TahirZX:
Can u help me on how to get s-off for desire eye? Like what are the steps? So let me get this straight. First s-off then get twrp 3.0 then get the rom right?
[HTC Desire Eye] karanm18:
You can get S-OFF from this website https://www.google.co.th/url?sa=t&s...xj123dBVofDHH3h7g&sig2=MJZxsMNukf35n_njErI8nw

You need to be rooted in order to S-OFF and once done you are S-OFF get anything you want on your device... Root is the only requirement for S-OFF

P.s. it takes 25$ to S-OFF

I'm considering using my Jump upgrade to get an Edge+ or an LG v10. Has anyone had any problems jumping with a rooted S6?
[T-Mobile Samsung Galaxy S6] ktrinh4213:
This was my worry when I was jumping from a Galaxy Light (which I hadn't used for over a year) to my GS6, and the service agent at the store told me that they do a 3-point check: if it turns on, if there's physical damage, and if there's water damage (or something along those lines). They don't check software or firmware, they just need to know if it's in good usable condition.
