[Q] Eng-Hboot does not start - G2 and Desire Z Q&A, Help & Troubleshooting

Hey y'all!
Just noticing a problem after I installed my Eng-Hboot.
When performing the button combination, my phone vibrates and then the Green LED is on.
After this, the screen is "on", but does not display anything.
I've attempted to reflash the Eng-Hboot, but the problem persists.
Help would be greatly appreciated.

are you on a rom that gives you the option to reboot into bootloader from the ui?
see if you can get in at all.

it seems like more people are having this problem as soon as i posted about it! i actually do think its a software issue although today a t-mobile rep told me it is a "known issue" with the earlier production G2's
http://forum.xda-developers.com/showthread.php?t=1096406
Also, i want to make note i did not flash a new hboot, but my phone responds the same way.. i'm trying to flash stock rom & radio but doing so from a blank screen that "would" be hboot, although adb won't mount or connect to my device. I can boot the device fully, mount, and then "adb reboot bootloader" and get to the blank screen, perform necessary pushes to load PC10IMG.zip, no luck so far

Really? That's interesting. The current g2 I have is a replacement (with one dead pixel, auughh) and I have only ran into problems with this device.
I guess I'll be getting a replacement if my phone even semi-bricks... yikes.

Flashed wrong HTC stock ROM...I have SLCD screen, need help.

I tried to go back to unroot and stock HTC rom, Flashed wrong ROM, downloaded BOTH, now, phone vibrates one time (like its supposed to), but the screen does not work. Charge light does not work as far as I can tell so far.
Is there any way to get this back working or is it pretty much gone?
Edit: Charge light comes on..
Can you get into recovery through Hboot? Power it on while holding down the volume down button and see if Hboot loads.

Nope, I downloaded two recovery images. One for SLCD sreen and one for the other screen. I looked, and apparently flashed the wrong one. I get just a black screen.
So, you can't get to recovery, not even Hboot? If Hboot is black, I don't know if there is much you can do...

If I cant get HBoot to open..or anything for that matter, will verizon be able too? I took it to the store, told the guy very simply "the screen wont show up and nothing happens besides the single vibrate (as usual) on start-up). They hooked it to something...had the phone for about 20 minutes. Then came back and told me they ordered another one...
Edit: Once the recovery image flashed, Hboot came back up initially. S-ON was displayed. S-ON was the one thing I am glad happened.! lol
LOL, I hear you, I had a similar issue with my PSP a few years back. was getting random memory errors, and crash to reboot. I had enough sense to flash it back to stock fw, before bringing it back in. it crashed around 78% thru the stock fw flash. So that was kinda a godsend, since the only data they will be able to get off of it if they try, is stock.
Well your issue was the image you flashed. You went to unroot and flash a stock 2.1 ROM. Although this sounds correct, there is a problem. The stock 2.1 ROM was made for the release DInc's, and those, my friend, come AMOLED. So by flashing that stock 2.1 ROM, it does not contain the correct hardware drivers to support the newer batch of DInc, the SLCD.
What you could have done was:
Download the correct ROM that supports the SLCD from here (which can be found on http://dougpiston.com
Place that file in the root of your sdcard.
Now since your phone's display doesnt work, like you said it vibrates once, like normal, your phone still functions properly.
Boot your phone into HBOOT and allow it a few minutes, like normal to find this PB31IMG.zip file. It then will prompt you to press UP to confirm the update or press DOWN to not update. (you will not see this, but if you have flashed a radio then you know this process)
when you press up, it will then start updating to the stock ROM. however, you wont see any of this. just a black screen.
allow that to run, usually for 10 minutes. to be safe wait 15-18 minutes and then press UP. When the update is complete you are asked to reboot. UP for yes DOWN for no. again you will not see this. Then when it reboots....you will be happy and see the HTC Incredible white screen
It got me too, same thing you did. Just dug around and figured it out.

Thanks for posting this. I would push thanks but I'm on my phone. All to often people run into this exact situation and don't realize there phone is still working normal. They just don't know it because of the black screen. For future reference those are great instructions.

boot loop - probably bricked

Hello,
I wanted to debrand my htc wildfire s, and after many unsuccessful attempts (main version older) following other tutorials on the forums, I finally went to this one:
http://forum.xda-developers.com/showthread.php?t=1162971
Followed it step by step, everything was as expected until the flash in the end finished and the phone, instead of booting, entered boot loop.
Now when I try to boot it or to enter bootloader, the backlight turns on for a second, turns off after that, then again turns on for a second, off... and etc. It doesn't even show the HTC screen. When I turn it off and connect it to usb - it charges.
I am already assuming the worse, but if anyone has any ideas, it will be great, as this is my girlfriend's phone and I can already see the tears in her eyes when she understands the phone is dead... :'(
Can you get the phone into hboot?
Pull battery,
then put it back in,
then hold volume down and press power while still holding volume down
If luck is on your side you should be in hboot
Unfortunately I have tried that already - still the same backlight on / off / on ... loop. :-/
Try battery out, back in, connect USB, then try to boot into bootloader. See if your PC picks it up. If it does try to issue the fastboot command "fastboot reboot recovery" and see if it goes.
Also does it vibrate when its having its flashy seziure?

Hi,
Thanks for the suggestion. Tried that also - unfortunately - no vibration (qualcom diagnostics seems to not be the case - unfortunately).
Connecting it to usb brings the orange "charging" light for a 5-10 secs, after that the phone tries to boot and enters the bootloop again.
I think after 5 HTC phones, I will finally have one matching my avatar... :'-(
Hmm. Does the PC pick it up at all?

No, it doesn't

Whoa, I wouldn't be so hasty. Try taking your old one to a service first, it'll cost you a lot less
@johnnyspritz
I am thinking about sending it back to repair, the phone is still under the 2 years warranty. However if they find a way to read the contents of the boot or system partition (JTAG?), they might have some arguments against applying the warranty :-D
Hi Simaka,
Like you my phone is in the same boot loop....
Can't access to Bootloader, no HTC Logo.
I have try to contact HTC, but the mail they send me was out of context ....
If you find any solution, please share it ;-)
Hi, for sure I will. For now I will try to return it in the shop where I bought it as it is still s-on and locked bootloader, so they might agree to take it back. I checked the possibility to buy JTAG connection equipment, but it amoints to 150€ with shipping, plus probably a month or 2 of troubleshooting...
One interestimg thing to note is that during the procedure described on the link above the current rom version in misc.img before editing it was 9.9.9.9
I believe this was a way of artificially imposed restriction so any attempt to update would fail...

[q] htc g2 not rooted semi bricked boot looping please help

Long story short my friend gave me a T mobile HTC G2 because it didn't turn on. I opened the phone to find the part where the battery connects to the phone came off the mother board so i solder it back on put the phone back together and turned it on. It booted up normal and came to the lock screen nothing worked the touch wasn't responding so i push power button to turn screen off and then again to turn it back on and the screen worked. I tried guessing his pattern five time and it didnt work it asked me to sign in to my Google account when the screen came up the phone rebooted and it kept doing it every time i turned it on. So i looked on xda how to restore it tried it and im not sure if it restored or not but it strated boot looping. I tried the flashing the pc10img.zip from the root of the sd card it usually says something like version to new or to old or something it didn't work. My phone is not rooted and i don't think usb debugging is on. Any info you guys want just ask. What can i do? How can i fix it? Please help
I'm going to take a guess, that if the battery connection to the motherboard 'broke off', then it's possible you have other physical issues such as the ribbon cable connecting the screen/digitizer to the rest of the phone.
If it were me I would have sent the phone into HTC for hardware warranty (which you can't do now since you soldered it.).
Can you provide some specific information about the phone, can you get into the boot loader, and if so what exact information do you have there? (USB debugging would be easily turned on under system settings, if you can get into it via the screen).

Thanks for replying i don't think anything else is wrong with the phone all the cables were fine. To begin with warranty was already finished. "Yes", i can get into the boot loader/H boot. I can turn on usb debugging because the phone doesn't boot all the way in to android. When you say information what exactly are you looking for?

when you first had the phone it won't boot right? but when you tried fixing the battery connection thingy (sorry I don't know whats it called )
it booted and ran again?
have you tried doing a factory reset?
Power button+volume rocker down (volume down button) to boot into bootloader mode then do a factory reset maybe that would work ?

Would probably have to stick to the original Stock RUU update since you're S-ON (would need S-OFF for any kind of custom recovery, kernel, unsigned packages, etc), so would have to use a signed full package from T-Mobile, I don't know much bout that because I usually have my phones rooted and away from stock as fast as I can.
What stock rom did you find before? links?

Thats is the above link i used and i used all the ones that start with "PC10" I rename them to PC10IMG.zip so the phone can recognize it and it did. The only problem is that after it tries to install is say something along the lines of version is older or newer since i tried multiple packages. One package was going through the process and after that it didn't do anything, it didnt say failed or reboot or anything like that. Ive been trying to fix this for like a week and a half now. Ive even flashed custom PC10IMG.zip to see if it could help but nothing the furthest ive gotten is the phone boots for like 2 seconds the screen is blurry and the shuts off and there is an orange light in top right that wasn't lighting up before. Here are the links for the custom packages

You would have to much it to your exact carrier/phone, Just flashing whatever you get your hands on can be very very risky.
For example for me being on T-Mobile with a T-Mobile branded G2, I would grab PC10IMG_Vision_TMOUS_1.19.531.1_Radio_12.21.60.09b_26.02.01.15_M2_release_149459_signed.zip from http://forum.xda-developers.com/showthread.php?t=971109
(noting the *.15 is the original radio my device was shipped with, though I've upgraded to the newer *.19)
I of course have no intention to returning to complete stock, but it's usually the only course of action for most people stuck with S-ON (and then would look into exploiting/unlocking/rooting again from there).

Same problem, but desire z S-ON
Hey guys.
I have the same problem with the boot loop /semi brick. Expect I never had any problem before, with the phone. I have tried taking out the sd card, starting it agian. I have tried without simcard. I have tried to flash the ROM with RUU_Vision_Gingerbread_S_HTC_WWE_2.42.405.2_Radio_12.56.60.25_26.10.04.03_M_release_199043_signed
via Hboot Fastboot USB PLUG mode (which was the only mode the aplication was progressing in until it want to restart the phone in bootloader), but the phone frezzes and the aplication on the computer just keep working, without progress.
The factory reset just frezzes the phone.
The only thing reali seem to not frezze the phone is the revocery option. Here the phone react with restart showing a image of a phone with two green arrows bent around, over the phone. then it turns off the display and vibrate 4-5 times, og stays turn off not reacting to anything other then taking out the battery and you can start the phone once again.

Unable to get into bootloader or recovery mode, stuck at white HTC logo screen

Hey everyone,
I have read the various topics with a similar title but none helped.
Here is my problem, I bought a used HTC Desire on eBay. It booted just fine on the first start, then I did a factory reset (from within the Android system menu).
Since then, I'm stuck at the white screen with the green HTC logo. I have tried to get into bootloader mode by removing the battery, holding vol down and power, but it just goes straight to the white screen again.
Also connected the phone to the pc, but adb isn't picking up anything...
Any ideas?
Try Power+Back button.
just got one step further:
I can get into fastboot mode with BACK + POWER. But volume keys doesn't work, is that a known issue that I can solve somehow?

Then you'll have to flash a RUU to make it work.
http://forum.xda-developers.com/showthread.php?t=1772499
It's official HTC Firmware. Your phone will boot after this.
So:
1. Install HTC Sync.
2. Download and extract the RUU.exe from the zip (It's somewhere in there)
3. Run the exe while you connect your phone in fastboot (Power+Back)
4. Wait for it to install
5. Boot

Weird.
This may be the reason:
Now, that may not sound too bad to some of you, but there's more: the 2.3 RUU update is limited regionally, as well. It's not available to users in Germany, North America, South America, South Korea, or Japan.

Ok. Tests are done.
According to the screenshot above and the 7 vibrations, you have a radio brick. It's a brick that can hardly be overcome.
The only solution is flashing the RUU and hoping that the phone will eventually boot.
That's why I don't buy second hand phones.

freecer did it, was able to flash the 2.3 RUU again successfully. But now I'm back at the bootloop, but now, it simply does vibrate once (no more 7 vibrations) and reboots after some seconds.
So what can I do now? RUU flashed successfully, I'm running out of ideas...
and again the freezer did it, put it in, normally started via POWER button, it booted right through into Android.
Well, let's see if it keeps running now or if this overheating issue also exists in normal operation mode...
Thanks so much for you help so far, the freezer hint saved this device and hopefully will make my gf very happy tomorrow
Hold on I thought it was some pvt1 devices that had overheating issues.
Thought it was fixed on your newer ones. Then again I've never had a problem with my pvt1 desire flashed both hboot and find countless times.

it is a PCT3 device.
but the overheating-reboot issue is rendering it useless. I can use it just fine outside (-2° currently) but as soon as I'm inside, boot-loop...
Anything I can do from a hardware perspective to fix that? Sending it in for repair/replacement is not an option, it's simply not worth the cost.
do you think installing a custom rom of any kind might help?

It's a motherboard fault. If you don't send it to repair, you just got yourself an "Ice-Phone", or a very complex paper holder.
i think a custom rom would help a small bit, like the rom in abaaaabbbb63 sig (mildwild redux) because its small and lite unlike a sense rom. therefor it mite not overheat as quick or as often. but thats only a guess. the only dodgy thing is trying to get ur phone s-off or rooted because if ur phone overheats in the middle of the s-off/rooting progress u could brick ur phone. plus charge ur phone using ur computer coz it uses less power and the phone does'nt heat up as much as plugging into the wall.

[Q] Screen flickering / Bootloop -> Is my Nexus dead? Data recovery possible?

Hello,
just some hours ago my Galaxy Nexus (SC-04D) rebooted while lying on the table next to me. After several sings of vibration I noticed that the phone doesn't boot completely.
When switching on the phone I get the turn-on-vibration, then the google letters are displayed. Most times the word "google" flickers from left to right over the screen (only the line where the word is supposed to be). Sometimes it boots further and I get the colored "X" displayed. This symbol starts flickering, too and if it went so far it reboots.
Here are two pictures I took from the phone failing to boot:
picpaste.com/img_0001_01-Rmm7kDYb.jpg
picpaste.com/img_0001-eoLqVoiM.jpg
The phone is running stock Android from Docomo. The phone is about 14 months old and has never been unlocked, rooted, modded, taken a bath, ... 'til now.
I tried starting with and without SIM-card, with and without charger attached and let it lie around for several minutes without battery between my tries.
Is there any chance to get my data from the phone or even get it fixed? Please give me a hint what I can do.
Well the Red exclamation mark means that there is a problem with the phone reading the build path. Since you have never rooted the phone, this would mean that the files got corrupt on the phone. With a non-rooted phone a Factory Reset is about the only solution, but is probably only a temporary fix. This is most likely caused by too many apps on the phone and it just freaked out on something eventually.
I think these options might work for you, however I cannot confirm since I have rooted my phone from day one and never looked back:
Power button + up volume= recovery
Thanks GPFboy for your fast response,

As far as I understand a factory reset results in a complete loss of data on the phone, right? So without root/unlock there's no chance to get my data from the phone? That would be really bad.

What is "too many"? I think there are about 35 apps installed atm. By the moment the problem arose wifi and 3g-data,BT,GPS were disabled and just a minute before I took a look how late it was. So nothing special.

The phone reaches fastboot mode, but when selecting recovery mode I get the google logo and after that the open android with the red exclamation mark. That doesn't look good, does it?

thats stock recovery.
is your bootloader already unlocked or no?

It's still locked.
you might try and go into recovery,
then press (i think) power and vol up and try and see if you can wipe just cache.

ok, I tried that several time now, but it didn't work. The only thing when I select recovery and press the power button is that I get the google logo and then the dead android + red exclamation sign, but this screen is scrambled and shows flickering pixels as shown in one of my pictures in the first post. So recovery mode seems not to work for me?
Is there a software or hardware problem with my device?

You can try to unlock your boorloader and flash a custom recovery like cwm or twrp. Maybe that helps. You can always go back and re lock it.

He wants to keep his data... which, at this point, seems rather impossible.
If fastboot doesn't solve it, i would try omapflash, OP. That "flickering" doesn't look good.

Well if I was him I would be more worried about my expensive phone instead of data. Maybe a lesson for later to have a backup

Yes exactly this is the point. Since I don't have a current data backup the first thing to try is getting my data from the phone. I already tried temporary loading the clockwork recovery through fastboot - with the galaxy nexus toolkit and by hand(sdk) - but it failed ("Bootloader locked").
What I'm wondering about is the fact that the phone seems to behave normally in odin and fastbood mode but going nuts the moment it's expected to boot. Besides the flickering google logo and the "matrix-modded" dead android it even ended up in a totally green screen one time.
At the moment I don't dare trying to unlock/flash the phone because of being afraid getting stuck and ending up with the phone being in some kind of undefined / totally broken state. Initially I was in hope of being able to rescue my data but now i will try my luck with docomo support first.
As far as I understood omapflash is primary used for recovering bricked phones not even starting to odin/fastboot mode. But thanks to your hint I found http://forum.xda-developers.com/showthread.php?t=2016628 "Unlock bootloader on GT-I9250 without wipe and without root" This might bring some chance for data access.
I will try to get through 1 to 4 of the guide first and see how far I get.
If this won't work I might try to unlock, recover and try to "undelete" what's possible. (http://forum.xda-developers.com/showthread.php?t=1994705)
Does this order make sense?
Btw, having a dead phone is bad, of course, even when I got it new for 2300Yen but loosing some pictures i really liked and having no phone atm currently hurts more. Especially when knowing that I was thinking of copying all photos to my computer only one day before when I pulled only some minor important ones from the phone I needed for work and planned to do a full backup and unlock this weekend when I get back my 'Milestone' currently lent to someone else.
Once again something I learned. Backup! Even you phone.

It will work actually, I read/also replied to that thread! I had forgotten about it, sorry. I must say that if you had already read the stickies that matter, you'd already know about it.
It will unlock your bootloader, bypassing fastboot. Still, it's not for the faint hearted. I refered to omapflash because its a low level tool, it doesn't require the bootloader to be unlocked, and is able to restore the bootloader to working state, and I got there because you mentioned you see graphical glitches/flickering which may indicate bootloader partition failure and/or consequent corruption.
I think that's your best shot at trying to get your data back. After unlock, boot to fastboot and 'fastboot boot custom_recovery.img', and grab your stuff (if you can) from /data/.

Your hint was very helpful for me getting the right direction since I'm just starting to dig into all this stuff.
Unlocking went quite well. Writing back to the phone worked without a problem and after that it's shown as unlocked in fastboot mode.
It even started loading clockwork recovery with fastboot. But the initial cw recovery screen (their logo and the cw recovery footer) was already shown on a scattered screen (google logo + unlocked lock was fine). After that the usb port connected and disconnected several times, then the screen went blank.
May this be because of corrupted fs or defective hw?
From my understanding with omapflash one have raw access to the phones internal memory similar to with dd on Unix/Linux. So currently I'm trying to dump ("upload") the emmc from the phone - actually in smaller chunks since omapflash needs to allocate all the memory in advance for the upload and to prevent interruptions. This will take a while...
After that I want to try to 'cat' the parts together and mount the filesystem - might be possible to do this from linux since it seems to be ext4 filesystems

Great, so far so good.
Yeah, they're ext4 images, but sparse images i believe - link
