HTC Incredible :: Flashing Kernals And Slcd Screen
Oct 22, 2010
Flashing kernals is new to me although general rooting is not. Apparently with my new Inc I have the slcd which will only work with a few kernals. What I had to do to get some new ROMs working was flash the ROM, then flash a specific kernal before booting up. That worked and I was able to flash some ROMs that I was not previously able to use. It has come to my attention that there are some kernals out there that are better for battery life so my questions are:
1) If I want to flash a new kernal over my existing ROM can I just do that? Boot into recovery and flash the new kernal? (After a nandroid of course.) Or do I have to flash the ROM again, then flash the new kernal and then boot up? Do I need to wipe anything before flashing a new kernal?
2) What are the best kernals for battery life that work with the slcd screen?

I have tried flashing several kernals with different ROMs, but more often than not, my phone just ends up restarting over and over. after i boot it, when i flash the kernal, I would be playing with it then all of a sudden it would freeze up on me and start boot looping. I have cleared the dalvik and cache before flashing ROMs and kernal. I rooted via 3.21 unrevoked and it says on the top of hboot s-off. The only kernal that has worked is netarchy-toastmod 4.1.8 bfs. any idea what i could be doing wrong?

I just put Froyo 2.2 on my Moto Droid using this ROM: http://androidforums.com/roms-droid/127966-rom-stable-android-2-2-frg01-clean-untouched-virgin.html
And I used the 800mHz kernal found here:
How To: Get Android 2.2 (Froyo) On Your Motorola Droid Right Now! | TheUnlockr
I am experiancing a few freezing problems and bad start ups, but I am assuming these kind of surprises come with flashing different ROMs/kernals onto your phone. I noticed, however, that occasionally my screen will get really "twitchy" e.g. when I press a key on the android on screen keyboard it types the letter 4 times. or when i drag the notifications bar down half way and keep my finger still i can see the bar twitch up and down rapidly. I have heard from several review sites that twitchiness and stuttering usually have to do with the processing, which made me think of the kernal change. Does this mean i picked a bad kernal or a bad speed? If i get this twitching does it mean get a faster kernal or a slower kernal?

Finally received my Desire form Vodafone yesterday after waiting 3 weeks. Was wondering if there was anyway of telling if you have an AMOLED or SLCD screen?

I have a T-mobile UK Desire which arrived on 30th July. I'd like to root it and load froyo but I'm baffled as to which process to use: I have 0.80. Turned on the phone while holding back button which gave these details:
BRAVO PVT1 SHIP S-ON
HBOOT-0.80.0000
MICROP 031d
TOUCH PANEL-SYNT0101
RADIO-4.06.00.02_2
Mar 29 2010, 21:34:33
I don't have access to the packaging but I'm fairly sure it said 3.7 Touch Senstive Screen (no mention of AMOLED). I've tried having a look at the black hue the screen displays but this just confused me since I don't really know what i am looking for / got nothing to compare it to. This post has confused me further: "SLCD will NOT work on HBOOT 0.80" lollylost100 Senior Member [FAQ] HBOOT 0.83 / 0.92 / SLCD - rooting and recovery - xda-developers. Was 'lollylost100' correct and I DEFINETLY have AMOLED just because of the HBOOT version? Or is it possible to have 0.80 + SLCD?

I searched many forums but there seems to be no clear way to identify the screen type other than by eye. Clue #1: The box has no mention of AMOLED. Clue #2: P/N is 99HKZ009-00 Clue #3: Made in China Clue #4: Unbranded, unlocked phone bought from a US retailer. My plan is to root. According to what I've read so far, the method depends on the type of screen, SLCD or AMOLED. I need to know for sure, so as not to brick the phone.

If I get a Desire with SLCD instead of AMOLED- does this mean the screen has a true 800x400 resolution instead of what has happened with the Pentile screens? I know, I know, its not really noticeable- but wouldn't hurt to ask right.

Is there a way to check if your screen is a AMOLED display or SLCD. Without looking at the box it came in.

MY SITUATION: My phone was rooted with unrevoked3. I tried to install one of the modaco ROMS and did not realize that it was incompatible with my phone because my Desire has a newer type of screen (not amoled) but SLCD. This caused the phone screen to go black on start up and be unresponsive. It was frightening because at first the HTC bootscreen (green HTC on white) had black streaks through it , then goes black. But don't worry it is easily redeemed in below instructions. You need the latest ROM in zip form, put onto your phone and run recovery. Sweet as suzi, you will be debranded (if you were in the process of doing this , remember to make your gold card).
ISSUE:
1. Desire screen not switching on at all even though phone switches on.
2. Phone boots but doesn't go beyond bootloader/recovery/fastboot
3. Can get into recovery even though nothing comes on screen (test: press volume down and power. Wait for 10 seconds. Press volume down. Press power. Phone should vibrate. Wait 20 seconds. Phone should now be in recovery mode.)
4. Can get into fastboot (back+power)
5. No goldcard
CAUSE of ORIGINAL AUTHOR'S ISSUE:
I had Aura Sense7.9+AlphaRev S-Off. Cause::Ran a very old RUU just because I wanted to bring things back to stock. The RUU overwrote my HBOOT from 0.93 to god knows what. Turned out, the RUU was for amoled screens and not for SLCD screen. So even though the phone turned on, the screen never did......

Droid Incredible transitioning from AMOLED to SLCD touchscreens this month | Android Central. I thought it was just N1 and Desire, as HTC didn't mention Droid Incredible.

I already had my Incredible replaced a few months ago, but now I am having trouble with the replacement, and I'm thinking about getting this one replaced with another certified replacement. However, I'd much rather have the SLCD screen because the text is much sharper since the screens use the typical RGB pixel layout as opposed to the RGBG PenTile layout of the AMOLED screens. This is the one reason I can't stand the AMOLED screen, you can read more about it here...

I am currently trying to track one down from t-mobile as there has been many shortages lately but, anyway i was told this was because of the screens being changed to SLCD ones from sony. I know that sony do quality products and that but, will there be much difference e.g battery life wise, representing color etc. compared to the AMOLED screens.

Last night I exchanged my Fascinate for the Incredible due to some really poor call quality issues. Well, I am not a huge fan of Sense - mainly due to the swipe down action of answering calls and unlocking the phone but I digress. So I decided to root. I've rooted several phones before (Eris, Ally, Fascinate). I flashed the DInc last night using the unrevoked one touch method. Then I installed ROM Manager - paid version. ROM manager thought I still had the Ally so I went ahead and flashed the CWM recovery image included with ROM Manager and I think that caused a problem. Things just weren't working right so I searched the forum and found an image that I had to rename, put on the root of the SD card and then flash.
After doing that I was then able to flash the Skyraider ROM that I downloaded in ROM Manager. What I'm really looking for is a ROM with a Vanilla dialer so I tried flashing Cyanogen's 6.0.2 from ROM Manager. It downloaded but hangs at the HTC Incredible screen on bootup. Thought there may be an issue with the flash so I downloaded and installed it manually and it still hung at the boot up screen. I thought it was a problem with the cyanogen ROM so I gave up but I just tried another and am having the same problem. I flashed the MIUI ROM manually and it booted up the same screen and hung there as well. What am I doing wrong?

I was taking videos on my Dinc when all of a sudden the screen started to flash pink static. The screen is completely pink, flashing, and you can't see anything through it. The only cure is to do a battery pull. I've tried everything else but a factory reset. Has anyone else had this issue and has anyone figured out a way to fix it? This is now a daily occurrence and it is very annoying because I use my camera quite a bit and have to pull the battery every time to use the camera again.

Saw on Droid Life, they are now available. Went to my local BB just now and they are in stock. Wonder how these new screens affect battery life?

I just got a new Incredible with the sLCD display. Pretty nice phone, got it all rooted and flashed with unrevoked and noticed the clockwork recovery didn't give a display. So I whent ahead and flashed amonRA instead. Everythings working OK, but whenever I try and flash cyanogen or any roms similar I get stuck at the 1st boot screen (HTC Incredible) I have gotten a few roms to install but none of the ones I wanted to try unforunatly. Is this perhaps being due to the lack of support for the slcd screen? Does anyone have cyanogen installed on their SLCD Droid Incred?

I'm bout to root, and wanna run a Hydra kernel, but I wanna know if the recent OTA could mess with the way the kernels work. More specifically the fact that the OTA brought 802.11N with it, yet the kernel has the option for it. Should I not use the Hydra with N? Just want to make sure having the OTA won't mess with any functionality of a custom kernel.

I rooted my Droid incredible 2 days ago so bare with me as I am still trying to understand all this new terminology and get the fullest use out of my phone. I was wondering about Kernals, overclocking and underclocking. I would like to increase my battery life as we all know how crappy it can be under normal use. I am running Skyraider 3.3 now because I enjoy the stock look of the HTC sense and I am using ADW.launcher as well. I downloaded a kernal for Skyraider but I can't tell what the speeds are and change them up. I saw a program called setcpu for rooted users on the market. Anyone have any experience with this app and is it worth the money? I am not wanting to slow down the performance of my phone but I still want to be able to have a good battery life. Anyone have any suggestions for a kernal to use or anyone using setcpu have a suggestions for a good speed to use.

I ask for some clarification on ROMs, radios, bootloaders and kernals.I am currently running a rooted stock incredible. I want to try CM6, the 2.2 leak, and the 2.2 lite or Sky Raider. I know there are issues with having the right radio and kernal with all these. If I understand it right, the stock kernal will work with all of them. If I wan't to try another kernal I would be limited to kernals made to get along with those specific roms. Is this correct?I have the 1.x radio right now, which will work with CM6 right? If I go to the 2.2 leak it will upgrade it to 2.x, which will work with 2.2 lite or Sky Raider. However I am I right in thinking to go back to CM6 or stock from 2.2 leak I will have to downgrade the radio? Also, I will have to downgrade the bootloader as well?Whew, this is all so confusing.

i was wondering about the hydra kernals. I installed the latest overvolt hydra kernal. My question is when you go into idle, does it underclock for you? Or do you have to install undervolt to do that? Also can you install both overvolt and undervolt at the same time? (not literally at the same time but have both kernals at once to get the most power and battery saving?)

Was playing with the touch to take feature on my DI, when suddenly the camera started displaying flashing red and blue screen. Not sure what happened there. Battery out resets did not fix it. I did a complete data reset and it returned to normal. Anyone else experience this?

I rooted today (unrevoked 3 + forever) and I did a nandroid backup (thank god) and titanium backup. I tried to flash the undervolt (0.5) and overclocked (0.1, #1) hydra kernals on the phone but it gets stuck at the boot up screens. Am I doing something wrong? I put the zip on the root of my SD card and used Clockwork to flash the zip file. Should I just upload the HTC .32 kernal?

I have the HTC EVO 4g and used the unrEVOked method to ROOT my phone. I got ROM Manager and Titanium Backup Pro for all my backup/flashing needs. I downloaded cyanogen mod 6.0 (stable release I believe) and when I approve the phone to go ahead and backup/wipe my phone, it just goes to the bootloader screen. No code runs down, nothing happens. I rebooted and I still have the same ROM installed, the froyo 2.2 ROM. Any suggestions to where I went amiss? Also if I'm using the incorrect lingo sorry, I'm new to hacking phones and such

My dad has a Samsung Galaxy S Vibrant with the Super Amoled screen and I could barley tell the difference between my Htc Desire with Slcd and his phone. The only difference I could see is his blacks were a tiny bit darker.

I got my desire about 3 weeks ago and with a week i dropped it, shattered the digitiser and damaged the SLCD. I decided to "try" and do a self-repair - i bought a new digitixer and LCD (AMOLED). I know for sure that i had an SLCD as it wasn't branded samsung on the rear of the screen unlike its replacement which did. My problem is that the AMOLED won't work. my SLCD works fine (except the damaged pixels) so i know the handset itself is fine.

I just received a branded o2 desire with an slcd screen and have been reading various forum threads saying that making it unbranded may not work because it has an slcd - people have been getting black screens because drivers were not there? Is there a way to unbrand my desire without causing problems and also would i use the unrevoked method or goldcard? Also would i be able to receive OTA updates (official htc ones not o2 ones) after doing this.
