Flash Stock Kernel - HTC U11 Questions & Answers

I have the latest version 1.13 xxxx .european single sim model.
I want to flash the stock kernel of 1.03.416 official firmware.
how can i do that?

First off there is no way to flash the stock kernel of a lower software version while S-ON. A lower kernel on a higher ROM version would also mean you'd break things and maybe cause a software brick. The only way to use slower grade software and firmware would be to flash a lower RUU. But this is only possible if you're S-OFF.
As you see this is the same as I already told you via PM.

Even with unlocked bootloader and fastboot flash boot or via twrp?
(left out other part of quote as yes it may or may not boot etc.)

No, you can never go backward in software/firmware versions, unless you are S-0ff.

Thanks, but that was not my question or this thread question.. I see no reason why you could not flash stock kernel (I am not asking if it will boot or not, just if you can).

You can but it can only be same version number or higher than RUU that's presently in the phone. Kernels have version numbers too.

AFAIK you can flash almost anything to system, boot and recovery once bootloader is unlocked.. But as my question was can you (not should you), I'll let it go.
Thanks for the answers.

Yes please let it go, no here is going to purposely help you brick your phone without an explanation.

Yes, you cannot. If you need to cure any issues now, you use the Specific RUU for your phone model to take it to 100% stock.
If and when S-0ff is achieved for the U11, then we will be able to move forwards and backwards in versions, plus
other modifications that we can't do right now.

[Q] HTCdev.com Unlock - HBOOT cannot find Recovery Img.

I have tried everything under the sun, but I cannot get this thing to work. My phone will not find any recovery img I put on my SD card. No matter how new or old it may be. It is really frustrating. Can anyone help?
You're doing it wrong.
Take the recovery.img off your SD card and put it on your desktop. Then use fastboot to flash the recovery image.
Wait how do I use fastboot? I used a Mac to unlock my phone using htvdev.com's method.
My intentions are to also root my phone and install the new set Coindroid rom. Can I do that with my current setup? I couldn't use revolutionary because I own a Mac.
If you unlocked, then you know how to use fastboot!
To install the recovery you use
Code:
fastboot flash recovery recovery.img

ok well what about install a custom ROM such as coindroid and rooting the phone? Do i follow the same steps every time?
Nope, once you've installed recovery, you just enter that and install the ROM/root files.
Ok which recovery would you recommend? I am mostly used to ClockworkMod, but does the touch interface ClockworkMod work for the Sensation 4g?
Yes it does, that's what I use. You can find it here: www.clockworkmod.com/rommanager

Ok.
And the code for that would be:
Code:
fastboot flash recovery (what I just downloaded?)
TO OP: Coindroid is an ICS ROM. All ICS roms require updated "ICS" firmware found in HTC's 3.32 software update. Here's the problem, you CAN'T update your firmware (except for stock TMobile versions) because you didn't s-off. HTC bootloader unlock does not give you s-off and only allows for flashing rom, recovery, and in a round about way kernel. You need to update your hboot and radio by updating firmware, which, as i said, you no longer can do. You are now stuck on gingerbread based ROMs until TMobile releases their version of the ICS update next month. If you flash an ICS ROM you will end up in a bootloop.

hrm. Well if I root can I still get the update from T-Mobile? I want to remove the crap off of my phone. And then would it be wise to still install a recovery?

You would need full stock ROM to successfully install the update via OTA, meaning stock recovery and all system apps present.
**edit** I also added a little more info in my previous post, to give you a clearer understanding of what's happened.
Ok, So I only unlocked the bootloader via htcdev.com. Should I just leave my phone as is until the update then? And did the bootloader unlocker mess up my chances of getting the update?
I honestly don't know how HTC bootloader unlock may or may not effect OTA's, but I will say this, if you don't get the update or if you do and it causes problems with your device, you're on your own. Your warranty has been voided by the HTC unlock method and TMobile will not service the device so you will have to go through HTC which can cost $$$!

Won't there be a way to update it even if I don't get updated through T-Mobile?
EDIT: Also couldn't I just relock it just in case?
There probably will be. In your case, your best hope is that the official RUU for the TMobile updated software gets leaked and posted. They usually do. Look for it in this thread. Probably won't be available until sometime after it's official release.

Another quick question. Can't I just flash the GB Stock ROM and then update if I need to?

How do i flash radios on nexus 5

So ill try to make this short and sweet but i need help. since 4.4.4 i really noticed bad signal issues and with a speed test my ping is 160 making online gaming really bad. ( its the only connection i have where i live to play online before 4.4.4 it was fine ping was like 70ms)
So i figured out the to get the radios say from 4.4.2 i would download the rom from https://developers.google.com/androi...s/images?hl=de
extract the file and the radio file is inside right. now how do i flash it. using Android SDK is there a tutorial or video somewhere. And can i use the roms from that site on a canadian nexus 5 my 4.4.4 build number matches the one on the site so im guessing yes.

From start to finish, skip over what you've already done.
1. Unlock your bootloader.
2. Root.
3. Install custom recovery using fastboot,
Google TWRP Hammerhead and the site for the recovery image and instructions will show up.
4. Have the modems downloaded, search for the thread here in Nexus 5 forum.
5. Go to Install .zip in TWRP recovery and flash the respective modems.
Protip : look up how to make an EFS backup just in case you somehow manage to corrupt your IMEI.

Check APNs if that doesn't work then
Return to factory default.
Not much else you can do without root.

Which without root is impossible unless the OTA comes through and its dependant on the country you're in. You could flash the 4.4.4r2 stock image using fastboot.

You don't need to be rooted persay to flash a modem, just a custom recovery. It just makes things easier. If you're going to unlock for sure, rooting makes things easier even though you don't REQUIRE it.
Best of luck and let us know how it all goes.
Why not extract the radio from the Android image and flash it via fastboot? That doesn't require root, only the phone to be unlocked.

No, rooting it would not affect the unlock status, and yes it will still be unlocked if you flash a custom ROM as long as it supports it. Ex: if you flash an AT&T ROM, it will only work on AT&T

Make sure your device is updated with the latest firmware, or at least 1.57, because CyanogenMods kernel doesn't support anything below that now

There's not one released yet. And most of us flashed other things that made it difficult to update. Later I will upload the patched system. Img and firmware zip. So others can have Oreo if they aren't able to update. Only downside is we lose twrp until I make one for 8.0 or someone else does.

A big TTHHHAANNNKKK yyooouuu Twinnfamous. I made a big mistake & relived the bootloader & this definitely pull me out the tight problem I was in when my phone bricked
Anyone know where I can find the RUU now? That ^^ link is dead, and I'm finding it impossible to find it via google/duckduckgo

[rom] [n960u/u1] [8.1.0 arja] [root for u/u1] [prerooted]

Mod edit
any screenshot?
Aren't the 960U and the 9600 different?
Please wait for confirmation before flashing this on your N960U/U1 device.
Seeing things like this and getting excited. But poking through the zip it seems this is something you already need a custom recovery to be able to flash anyways sadly
You need a custom recovery installed for this too work..
Will Safestrap work on Note 9?
There is no way to install it with out custom recovery literally unless some one made it where u can flash it with Odin
Clearly the OP has neglected to do basic research on the Snapdragon Note 9. There's absolutely zero information on the firmware version, kernel or any other information about this ROM. In my opinion, this is against forum rules and should be removed for obvious reasons. This is the kind of things we DON'T want the public attempting to flash on the $1,000.00 phone. Most everybody is aware of the locked bootloader and inability to flash custom zips but for somebody to post a flashable zip with no testing whatsoever is just reckless and shouldn't be allowed because people are too trusting and will try to flash it.

No Odin you might have to use fastboot commands to flash this. But I am sure it would not work for us..
and why is this not locked down yet?
Is it fake?
There is no way to flash it without custom recovery or fastboot nor do us devices have a unlocked bootloader so it will not work at all unless unless u have a device that has one of the options or all 3
Do we flash this via odin?
I am reading and seeing this may not work? Do we have any confirmation this will work? on the n960u?
