Unlock your bootloader with omapflash. Although even if it does unlock, Your emmc/board probably has died.

[Samsung Galaxy Nexus] jhonnyx:
can you please me guide how to do the omapflash?

I've downloaded a file called OMAPFlash_tuna.zip.

- Set battery of the device aside

- Plug device into USB, let it detect the device and flash the SBF I think.

That'd be all?
[Samsung Galaxy Nexus] jhonnyx:
Pardon me, if EMMC/Board is dead; why does it boot or get into bootloop? There is something that reflashes itself; it even overrides odin or heimdall...

Yes, same method, still the same.

Weird part that NO one mentioned me is that when you unlock the bootloader, it'll still remain unlocked. Not in this case

I do fastboot oem unlock

then fastboot reboot-bootloader

loader is still locked!

I'm reading. did the exact steps at the 1st post and bootloader is still locked. Damn it. Also re-dumped param.img into param2.img after the flashing and it reverted!!! how come???

[Samsung Galaxy Nexus] Daedalus93:
I don't know if this has anything to do of what you've just said but after flashing a custom kernel and a custom ROM (second time flashing on this phone) it did work out fine. And was able to do everything for a few hours. But suddenly it restarted (wasn't doing anything at the time) and it entered in a bootloop. Knowing that those things sometimes happen I went to the recovery and restored the image that I've saved previously (everything stock unrooted). Bootloop still there.

Then I downloaded the official Google Image and chose to flash everything. Everything on the installation went fine but the bootloop was still there.

Suddenly Fastboot wasn't working on Windows 8 as it previously was. Reinstalled drivers and nothing. Couldn't send more fastboot commands from windows. Then tried Odin with stock image + fixing partition table. Bootloop continued.

Note that the device was able to boot in Odin Mode and in Fastboot Mode.

Then I left the device rebooting and after 10 minutes more or less it booted and displayed the Android Welcome Screen. Then it started the bootloop again. :crying::crying:

Is this hardware fault? Has the flashing of the ROM and Kernel done anything to the device or was it just a coincidence? Has this been fixed somehow (if it is hardware fault)?

Note: I could run fastboot commands in linux so I locked up the bootloader because I'm going to send the phone back.
[Samsung Galaxy Nexus] jhonnyx:
At least you were able to work on the bootloader; Even after rebooting, it locks again. Thanks to all the people above for their efforts. It would be great if somehow the program and/or code to erase/reprogram the EMMC thru OMAP would be available
[Samsung Galaxy Nexus] Daedalus93:
But I'm a bit out of context here because this is the first time that I see anything like this. I've searched a little and found that brickbug thing. Now I know that there are apps to know if the chip is faulty or not so I'll do that when I receive the new phone.

What triggers this? What I did was flash a new kernel -> device working for few hours ->device rebooted + bootloop -> restore via Recovery -> bootloop.

I've read that Samsung somehow fixed this in one of the JB Kernels. Does that mean that the danger lies in flashing a new kernel? With stock kernel can I backup and restore without concerning about the brickbug?

I just don't want to brick the new phone again :/
[Samsung Galaxy Nexus] Lanchon:
a good SSD, even if small, will change your computing life. absolutely go for it. problem is, the interwebs is all hot over the samsung 840 drives, bloggers cant stop praising them, but i got my doubts. forget the fact that they are using inferior, untested and less dependable TLC flash (on the 840s, the 840 PROs are MLC), what worries me is that they are samsungs! here on xda we know that time and time again samsung has been unable to output a working eMMC firmware. the eMMCs are crammed with features (seriously, they even got interruptable writes and erases in the latest firmwares) but their software testing in this area at least is obviously flawed. do i think the same people with samsung are behind SSDs and eMMCs? with similar software processes? do i expect the same output quality? yes yes yes, unfortunately.

if i were you i'd buy drive using a sandforce controller, now LSI, and avoid samsung. (watch for the AES 128 bit key export limitation, which was applied to domestic products too due to a process bug on some controllers.) also other manufacturers are still using MLC at samsungs TLC prices. you cant go wrong if u get a good 120GB for $90 bucks or less and move your system there, you'll love it.

me i'm screwed. im running from an old samsung 128GB SSD from before all these eMMC nonsense was known. its a PM830, a professional data center product, not the consumer crap, but still samsung... :(

SSDs can have, say instead of 8 flash chips, 9, and the controller can run the chips in a sort of redundant RAID mode. for 12% extra flash cost you can get near RAID safety. this is extremely important IMHO and usually not found in the price driven consumer market. try and look for something like that maybe. tell me if you find something interesting.

---------- Post added at 10:09 AM ---------- Previous post was at 09:57 AM ----------

forget it, it's not your fault. there used to be a clear trigger, brickbug, on eMMC erase commands. the commands were eliminated from bootloaders, recoveries and androids. then there was sudden death syndrome. now only nonpredictable sporadic errors remain, or we havent found triggers. its very possible that some physical flash defects may put the eMMC firmware in a hard untested place (this means no triggers on our parts) and it fails horribly. if a new trigger is found by the community, we'll all know about it. meanwhile its not your fault.

on your new phone just make sure you check that you have a sane chip before using fstrim (TRIM/erase) commands or apps that use them. use an app to check the eMMC.

before you relock make sure u are as stock as possible, especially the recovery.
[Samsung Galaxy Nexus] Daedalus93:
Many thanks. I've been searching about this brickbug but I can only find relevant posts from 2012 and as you said now it is unclear what triggers it. So I was kind of lost because what happened to me was something that wasn't one of "default" triggers that everyone talks about. It didn't happen on "Clear Data/Factory Reset". After I receive the new device I'll run that test app (and need to root it - hope I don't have some weird problems there...). But even if the app says that it is a sane chip can I flash new things or is there always the possibility of having the bug?

Some say that JB kernels are also safe but I'm not sure about that because it happened when I flashed the latest FancyKernel.

Yes I used Odin to return to full stock and then locked the device. :)
[Samsung Galaxy Nexus] Lanchon:
the eMMC check app doesn't need root. it just reads the world-readable files at:

/sys/devices/platform/omap/omap_hsmmc.0/mmc_host/mmc0/mmc0:0001/

ls that directory and cat the files yourself, get dirty :P

nothing in flashing should kill the eMMC. (unless you have the brickbug (rare this days) and u flash an unsafe kernel or something.) flashing is like any other write. flash wear and defects can kill the buggy eMMC no matter what you do. flashing a 160MB rom is as "bad" as loading 160MB worth of mp3s into the phone.

again, dont attempt to TRIM your drive if you have brickbug! (see lagfix app.)

you got a dud, you had bad luck, thats all. the new phone will work just fine, dont be afraid and tinker away.

take care!
[Samsung Galaxy Nexus] Daedalus93:
First thing I'm going to do is run that test. If it is rare nowadays then yay :D I bought mine 1 year ago.

So every JB kernel is safe to flash? (at least the more popular ones).

Many thanks :D
[Samsung Galaxy Nexus] Lanchon:
generalizations like these cannot be answered. you have to find your own researching vs. risk taking balance.

but i would say: no, samsung stock firmware could still be dangerous. i perceive it as certainly more dangerous than custom roms. so flash!
[Samsung Galaxy Nexus] Daedalus93:
Ok. Many thanks :D
[Samsung Galaxy Nexus] yudhafzn:
my device yesterday get same problem,to solve you can download program with name "nexus wugfresh toolkit" and follow the instruction
[Samsung Galaxy Nexus] jhonnyx:
Dear yudhafzn, please read the whole thread after posting. This problem cannot be solved by Wugfresh's kit nor reflashing with GNEXUS's toolkit. It goes beyond what software can do; unless you find a way to reprogram/erase the EMMC partition then re-populate it.

hey guys,

i'm running AOSP+ on my HTC device and it's very smooth but i'd like to try ANDROID REVOLUTION 7.0.

i'm using the BLADE kernel for AOSP+ 4.2.2 - do i need to flash to the stock kernel or can i use the blade kernel with ANDROID REVOLUTION HD 7.0?

thanks a lot
[HTC One X+] reaper90:
You have to flash another Kernel in order to install Andoird Revolution HD, AOSP Kernels won't work. you don't have to use stock kernel, you can also try hXORe kernel or elitekernel, which is based on blade kernel (although not latest version).
[HTC One X+] der_brecher:
thank you very much for your fast reply.

now i flashed the kernel with hXORe 1.3 and ARHD 7.0.. it's booting right now. hope it works and runs smooth :good:

hXORe 1.3? i hope you know latest version is 3.5 for international one x+ :D

[HTC One X+] Addicted2xda:
Core Manger helps you to optimize performance of this kernel.

For this you may try layapota's resource manager. (Don't install his mod pack as it causes issues with ARHD 7)

http://xdaforums.com/showthread.php?t=2221815
[HTC One X+] reaper90:
As Addicted2xda already said, you can change some kernel settings. Maybe you should know that by default this kernel only uses 3 cores on boot. So in case your not happy with only 3 cores, you have to run core manager after every reboot, set to 4 cores (or your desired number of cores) and press "Save & Exit" Button.
[HTC One X+] der_brecher:
thank you very much guys.

i searched in the Q&A forums but i didn't find coremanager. would you guys please give me a link?
[HTC One X+] Addicted2xda:
Check out post #9 in this thread!
[HTC One X+] der_brecher:
thank you very much guys.

i installed coremanager but there is no option for activating the 4th core or something like that, just this options:

hotplugging limit:5

charging limit: 80%

fastcharge: OFF GPU coupling: ON

selected IO scheduler: cfq

nothing else. dont know what to change :eek:
[HTC One X+] reaper90:
hoptplugging means enabling/disabling cpu cores depending on cpu workload, so the limit you may set there means the maximum number of cpu cores that are allowed to be online at the same time. The number "5" which is displayed there is a bug, you have to move the slider to get the correct number displayed. just set it to the number of cores you want to use and press "Save & Exit", remember this will be reset to 3 on reboot, so you have to run the app after every reboot and press "Save & Exit". and the app does not display the actual settings, it only shows the values you set the last time.

Or you can take a look at this: http://xdaforums.com/showpost.php?p=43409141&postcount=1086

i made a small script to apply settings automatically on boot, shouldn't be that hard to use.
[HTC One X+] der_brecher:
awesome, thank you! i moved the slider to 4 and pressed save & exit. thank you guys, you're awesome! :good:
[Sprint HTC One (M7)] Wicked_Girl:
Recently got an HTC One M7, and love the phone, but after firing it up on its wireless connection, I began noticing that my wireless network seems to be dropping its connection quite frequently. Upon closer inspection and reflection, this is not a new occurrence, but in our iPhone 4, iPad 1, HTC Evo 4G, ROKU XS, and several other OLDER wireless products household (albeit all on wireless N), I never noticed the disconnects as much as I do with the brand new phone now added to the network. I initially noticed the intermittent disconnect problems begin in earnest about four months ago and put them down to the usual crap-tastic service from Comcast, especially since we have had several full outages in recent months while they performed "service" in the area. I have a D-Link Gamerlounge DGL-4500 router and a Motorola Surfboard SB6120 modem. The firmware on the router is as up to date as it can be, and I have factory reset the phone twice, as well as applied all software updates.

So, here is my question...can a new piece of equipment like an HTC One place such a significant increase in demand on a potentially failing wireless radio portion of a router that it really magnifies the problem? I can stream movies over ROKU with no noticeable issues, but using the One in the Google Play store or the Blink Feed will send my router offline in about two minutes or less of use. My router logs show that each time I try to use the One wirelessly, I get the following message: "[INFO] Wireless system with MAC address XXXXXXX disconnected for reason: Received Deauthentication". This is not the only time I get this message though. I get it seemingly out of the blue as well. I have contacted Comcast, and they insist, as usual, that it is my router. In this case, they may be correct, since I do understand that the wireless portion of a router can go bad long before the wired portion. I did already order a new ASUS RT-AC66U router and a Zoom 5341J Modem, since it is probably time to do so based on the number of unmentioned wireless products that we use. But, can the new phone place such a load on the network? We have always been power networks users as it is, so what on earth would a little ity-bitty cell phone add to the mix? Hopefully, the new phone's wireless radio isn't defective too. My concern is to decide whether I need to trade this phone in ASAP while I still can. I already had a horrible experience in the past with Sprint and my HTC Evo 4G that I was stuck with. Thanks in advance for any input for a noob to the forums.
[Sprint HTC One (M7)] graycorgi:
It is most likely an incompatibility between the DGL-4500 and the wifi radio used in the One. I don't think your One is defective. There are a few (mostly older) routers that seem to have a problem with the radio used in the One (and some other wireless devices as well). I had a DGL-4300 that had the same problem with a specific laptop, and only replacing the router with a different model fixed it. I see that the last firmware update for your model was about 3 years ago so its probably time to upgrade anyway.

Replacing the wireless router will fix the problem. Your modem is fine and you didn't need to order a new one (the Moto SB6120 is much more solid than a Zoom anything).
[Sprint HTC One (M7)] Wicked_Girl:
Cheers!

Thanks for taking the time to answer my question. I was really scratching my head, having a gut instinct that your answer was going to be the case, but not knowing enough about networking to be certain. The One is a beautiful phone. My next task will be to spend many hours reading the XDA forums to learn about how to root it and install a custom ROM. I need to reclaim any memory I can from the crap software installed by Sprint that I will never use (including Facebook...sheesh).

BTW, I ordered the Zoom modem based on several things. One was the reviews of many Comcast users experiencing many of my current symptoms who also own my Motorola SB6120. It is also listed as one of Comcast's approved modems for the next tier of service when we decide to get it. Based on what you have said, I may just try the router swap first and see what happens there. That would save me some bucks! Thanks so much again!
[Sprint HTC One (M7)] bsmith427:
I can confirm intermittent resetting issues after connecting an AT&T HTC One to the DGL 4500. I wonder if the DGL 5500 (due out 8/1) will suffer the same problems.
[Sprint HTC One (M7)] eXplicit815:
You know what's odd about that, I have a Linksys WRT54G2 that is having intermittent problems with disconnecting from the internet overnight. It happened last night. When I woke up, my phone was connected to WiFi, but I had no connection. Each time, I have to go out to the living room and power cycle the router to get my internet back. Same issue?
[Sprint HTC One (M7)] jackzepplin:
Very interesting, and very similar to a problem I was having until recently. I kept losing my internet connection several times/day. I logged into the router and disabled WPS; problem solved. I recently moved to an apartment where there could be a lot of WPS seeking devices (including my HTC One) that were trying to connect to it. I won't get too technical, but disabling WPS solved my problems. Frankly, I'm not a fan of WPS anyway. It might be something for you to look at though.
[Sprint HTC One (M7)] ctiger:
Interesting to see such a post, I was using video call last time on my laptop and noticed horrible video quality, and turning off my phone's WiFi seemed to help a lot. I'm still trying to determine which to blame, I thought the QoS device I set up might have clogged the bandwidth before.
[Sprint HTC One (M7)] bsmith427:
The "fix" for me that I saw on another thread on this site was setting it to transmit on 802.11 G standard only. No more intermittent router resets.
[Sprint HTC One (M7)] Wicked_Girl:
While setting the router to wireless G only definitely fixes the problem, I did not buy high end gaming routers only to "cripple" them by using only wireless G. That ain't gonna happen. My DGL-4500 Gamerlounge router was specifically designed with gamers in mind, and it was definitely awesome. The ASUS RT-AC66U that I just replaced the 4500 with is another high end router. I am not dropping the signal at all in such a way as to be noticeable now, but looking through the logs carefully shows an occasional very quick drop every so often. It is curious, because my HTC Evo 4G started out with wireless N and then Sprint updated the software about six months after I bought it and removed the wireless N capability completely. That really pissed me off, let me tell you. So, to have wireless N problems still, with an HTC phone and Sprint, makes me highly suspicious. I would be curious to know if AT&T HTC One owners have the same trouble. I am willing to bet money they do not. Oops! Scratch that. I see an AT&T HTC One user above saying they have the same problem. Guess I cannot blame Sprint just yet.

I do appreciate your input though. I do not want to sound ungrateful in my above response. Another upcoming project for me will be to root my HTC Evo and see if I can restore the wireless N. then, I will just see if there is a problem with that radio. If not, I can place the blame squarely on whatever software tweaks Sprint places on these phones and proceed to rooting my HTC One as well, thereby thumbing my nose at Sprint. ;)
[Sprint HTC One (M7)] Wicked_Girl:
Hmmmm......

I find your answer extremely intriguing! I am pretty sure that WPS was disabled on my DGL-4500 router because I could never get it to work, so I disabled it. However, it is enabled by default on the new router I bought. I am going to try disabling it and see if performance improves on my network. I never use WPS anyway, preferring to manually set up my devices. Thanks for the input!
[Sprint HTC One (M7)] Wicked_Girl:
I have seen various posts on this problem advising to turn off QOS, however, since my understanding of QOS is that it is designed to prioritize the use of bandwidth properly so that things like streaming video are stutter free? Of course, everything can go horribly wrong in networking, depending on the overall circumstances. I currently have QOS turned off on my new router, but it was on on the old router. I will experiment with it later today to see if it makes a difference. I believe you can also tell QOS what to prioritize, depending on the settings available in your router software.
[Sprint HTC One (M7)] ctiger:
The router I have has a list for QoS devices, and if there's something wrong with that device, it might just gulp up all the bandwidth, I think, so I turned it off. But for the software QoS, which the router might try to determine which service should take the priority, I think I didn't touch. I did turn off the WPS as someone suggested, but didn't have a chance to test the performance of video call. Of course, I'm too cheap so I just got a 3MB cable service, if that's 6, it should be hard to mess up.
[Sprint HTC One (M7)] Aldo101t:
i had this problem with a BELKIN N router, i did a firmware update, and set it at n only(all my devices are n draft)works great now
[Sprint HTC One (M7)] Marcador:
My router started having the same issue as soon as i connected my HTC One to it, except my router is a D-Link DIR-655. The solution was similar to what bsmith said, I just turned off the 802.11n mode and had it mix between 802.11g and b modes. I did that a little over a week ago and haven't had any problems since.

My guess is that the frequency of the 802.11n mode isn't compatible with the HTC One's, but again, it's just a guess so I could be wrong.
