[Q] Reception...

Hello, i have purchased my Htc desire Hd a few days ago and i love it. I came across these forums and found them very helpful. I decided to _root my phone and install the latest Cm ROM and all went well. When i bought the phone the supplier (three) said that i would be able to get speeds up to to 6mb on the mobile broadband in my area. Sadly this is not the case as i am on EDGE.
I was wondering is there anyway to boost signal either by app or a different radio or ROM.
Thanks in advance.

Well, it could be from some setting maybe, but if i was in your shoes i'd ask the people in the Original Thread.
When upgrading from an fairly old ROM to a new ROM, i'd suggest the flashing of a new radio.
BE CAREFUL, AS FLASHING RADIOS ARE EXTREMELY DANGEROUS.
See the OP of the ROM thread and see if flashing a radio is mentioned (if its not mentioned on the thread, dont flash a new radio, or you can ask them if you can). Normally, ROM are supplied with a RECOMMENDED radio that works perfectly with it.
So ask the people in that thread (or see the OP) if and which radio you should flash.
FLASHING RADIOS COULD BRICK YOUR PHONE, AND ONLY YOU ARE RESPONSIBLE FOR BRICKING IT
- just a little warning with a happy face

Thanks alot for your time I didnt know flashing radios was as dangerous :/ i've done it twice. well thanks for the warning with the happy face
Is there any fail safes for flashing ? anything like roms or radios ?
Thanks in advance

By 'Fail Safes' do you mean 'a mechanism that manages failures and results in minimum harm'? (just googled it )
If so, well, android itself has MANY mechanisms. And by flashing ROMs, all it does is overwrite the current files. So flashing something (given that the script to flash it is correct - if not, then it wont flash - or could flash it to the wrong place) doesnt have any fail safes, which is why, if an incorrect radio is flashed, the phone wont do anything, but when you come to boot it, it could be bricked (worst possible case).
Flashing ROMs with errors can be fixed easily if you know how. Just build a flashable .zip file that'll overwrite the files that have errors with correct files.... - determining the error could be done by using 'adb logcat'

Thanks ! you couldn't have done more Thanks again for everything i will be more cautious when flashing Another big thanks !
Luke

Your Welcome , anytime

[Q] Xperia Play and Cola

So, I installed Cola on my XPeria Play - my first custom ROM ever, and also my first true "root" ever. Yay!
So, it seems like all is well... except, well, I can't access the 'net... period. I have no 3G/4G at all, and I can't enable wireless without the phone rebooting... and disabling wifi again.
Anyone experienced this or know what might be going on?
I would post this in the Cola thread... but, well, I don't have the required 10 posts yet... heh.
For what it's worth - all I want is a WORKING (fully) phone that doesn't have all the pre-loaded crap (like some of the games) taking up space.
(reposted from the general forums per another members request)
Yeah, I'm kinda new to the whole custom-rom thing... like I said, I really just wanted something faster that didn't have all the bloatware - it's the 800at as far as I can tell, but it looks like I can't unlock the bootloader (the info doesn't show when I attempt to view it, and from what I read here, that means I can't unlock it?)

I think you flashed a CDMA rom and you have a GSM phone, try my rom and see if it works, folow the Instructions and you'r done
http://forum.xda-developers.com/showthread.php?t=1631144

Is this from a stock kernal or Doomlords? If its doomlords, you might need to add the network modules.
I havent done this thing before myself, but have hung around the boards to gather the above advice.
Best of luck

I think he is talking about this rom:

As vokal1992 said, you flashed CDMA rom on your GSM (R800at I see) phone. That's why 3G/4G doesn't work and WON'T WORK AT ALL.
Sent from my beautiful Xperia PLAY using Tapatalk 2

Ah, aha... thank you so much! Lol, told you I was new to all this
I'll give the suggested ROM a try and let ya know how it turns out!

Well, quick update - i flashed the new firmware - that seems to have worked well, but I have no 3G/4G again - I'm attempting to install the new ROM now - I'll report back how that goes.
I did have one issue - my computer still reports that clockworks mod is installed even after the firmware flash... but I can't seem to run it within the system - I'll try to run it from boot to do the flash - if it doesn't work... well... I'll have to think of something lol
EDIT - so, further update... I can connect to wifi, but can't go anywhere on it, including the play store or to put in my google account info. I also still have no 3G/4G access... and clockworks mod doesn't work.
I'm... really not sure what to do at this point. Followed the instructions to the letter but... well, yeah. Now I've got a smart phone that apparently isn't so smart lol

Okay, so, in a "stroke" of genius, I realized that it was the APN's causing the issue (I didn't have any) - so I simply copied them over from my wife's phone (she also has an XPeria Play). So, yay, now I have internet access and 3g/4g again...
Now, next thing I need to do is figure out how to put clockworks back on this thing with my computer thinking it's already there lol
OH, and for what it's worth - at present, my network mode is WCDMA preferred / GSM - trying to use the GSM only doesn't work... at all SO I guess I have a WCDMA phone?
EDIT AGAIN - Okay, so I got Clockworks back on it, I'm re-rooting it now... hopefully i can get the ROM installed then!
New Edit - Okay, I'm at the point of using Clockworks to install the new ROM - however, it gives me an MD5 mismatch... hm...

Uh oh
Since you have the MD5 mismatch I would try downloading the file again. Also make sure you wipe the cache partition and Dalvic cache in advance before flashing.

You don't have an unlocked bootloader. You must install ROMs specifically meant for locked bootloader.

Far as I can tell, Vokal's works for a locked bootloader, does it not?
@ Zack - wipe the what and the who now?

Okay, so, the phone is working normally now with just the updated firmware - however, I still am having a few issues with MD5 errors with Clockworks, and I'm not sure exactly how to remedy this - found a few suggestions online, but I'm afraid to try any of them without a little more guidance

Koodo SGH T-989D

The tutorial for Rooting and all these ROMs present in android development section, are they the same for the T-989D Canadian version? Flashing them would work? I'm tried searching but it would just bring up roms based on T-989D. Just need a quick confirmation before I root and flash. Thanks.:angel:

I'm pretty sure that if something can be flashed on T989 (T-Mobile), it can be flashed on T989D (Telus/Koodo). I understand that the are just some small differences wrt access to download mode and recovery. See here: http://forum.xda-developers.com/showthread.php?t=2079776
btw, I have a T989D on Koodo

Short answer is yes! Everything you will find here is working perfectly fine on the canadian version.
So go ahead and root/flash away!

I have a T989D on Koodo which I've been messing with quite extensively, and yeah, everything is basically the same. The download/recovery mode linked above is the only major difference.
One thing of note, if you end up messing up the device and need to fully reflash from Odin, the t-mobile stock may not work. I tried over and over to recover from what was essentially a brick (ultra, ultra slow) and it just stayed that slow, even though it did seem to boot and connect and everything. It was totally unusable, however.
I found a different one that did work however, I can't seem to find the post anymore but I'm sure you'll be able to get it if you need it, there seem to be others out there with the same name, but not quite the same filesize. That shouldn't really matter as you'll doubtless go back to a custom rom anyway, the point is just to get you back to something that works.
For reference, the name of the one that worked for me is "SGH-T989_UVLH1_Stock_Odex_zipaligned_signed.zip" and it's 422 MB. This post seems to have a Koodo stock zip as well as the T-mobile one, it's about 100MB less but again, that really shouldn't matter so long as it's Koodo.
Hopefully you'll never need to use it, but I just wanted to let you know that even if you have to recover and some files don't seem to be working, keep trying, because the correct ones are out there! Just may need to search a bit for 'em

A few more things SGH-T989D owners may want to be aware of:
1) This is an excellent resource: [ROM][Stock]T989UVLI4 (4.0.4) ♛ T989DTLLE4 (4.0.3) ♛ T989DTLLG2[ODIN][TWRP/CWM]
2) You might want to search and replace all "T989" with "T989D" in build.prop
" " replace all "TLLG2" with whatever radio your new ROM is using.
If you're on Koodo you might want to assign that to the ro.carrier property
3) If you've got a data plan with you might want to search the web for your carrier's apn info and insert it into "Settings|Wireless & networks|Mobile networks"
Note: This stuff is optional in the sense that your stuff is probably going to work if you don't make these changes. I haven't always updated all this after switching to a new custom rom, but I did notice that I showed up on the Telus network as a T989 as opposed to a T989D on the Koodo network. Really they're the same network but ... I don't know. Maybe I just over think things... I do like the fact that when I plug my phone into the computer or go to the play store or whatever that my phone reports as what it actually is and what radio it uses etc. I don't really care that much as long as my stuff works and I have access to apps that are appropriate for the hardware I'm using. YMMV.
Note2: Most of this info can be gleaned from your stock rom's "CSC" folder and build.prop file. When I have a little more time I'll write this up so its more understandable for those new to flashing Roms. Just wanted to mention that there are a few other tiny, nearly insignificant differences btw the T989 and T989D so that the OP and/or others can address these points if they choose to. At least not be surprised if it looks as though they're using data on a network with a different phone.
Note3: Maybe the only thing that matters is an imei number from your SIM. I don't really know. Be glad to be "told" by anyone that knows. I just know that these things are different even if they don't make a bit of difference in practice.

Re:Koodo SGH-T989D
Hello I'm new to posting on the forums, sorry If I've missed the answer to this question already!
I have a Koodo SGH-T989D that I got in September, before that I was using a non smart flip phone . So I'm quite new to this whole rom business, but even android/ smart phone os in general.
I've been able to flash many roms in the past couple months and have a good understanding of what it is i'm doing. Never had an issue I couldnt fix myself actually, so I've never made an account.
This latest problem has me puzzled though, I've totally lost data connection on my s2x while using any radio. I use SGH-T989D_TLLG2_Koodo_radio but I tried UVLI4 just to see.
However I did change a few things up from my usual routine to flash 4.2.1
1: changed twrp to 2.4.1.0 from 2.2 cwm flashable zip
2: moved all my zips to sd card and formatted internal memory(to eliminate possible issues)
Before this I was using twrp 2.2 and only doing a clean install, not formatting internal sd without any issues or instability.
I've been on [4.2.1 | 4.2.2] AOKP :: jb-mr1 :: build 3 and very impressed with it, except this one issue.
In the thread there is a post that refers to getting data working with koodo, so I think its an apn/proxy setting. I just am not sure where I would have to change these settings.
Just restored a recent nandroid backup and everything works fine.
Can anyone help me out, any insight or tips would be greatly appreciated!
Thanks

Go to settings > wireless and network, more... > mobile networks > access point names > then hit your options button > New APN > enter the details found on the page linked above.
Hope that solves it for you.

Re:Koodo SGH-T989D
Thank you so much, worked right away!
The reason I didnt just look up koodo apn settings is because I had no idea what they were.
And Until now I've never had an issue.
Is this something to do with aokp 4.2 or is it because I formatted my internal storage?
Since mid December I've tried out about 5 or 6 roms just to see how they compared to stock. And all I have to say is wow!
Thank you to all those who make this possible, it really is a great community.
I was on stock koodo rom and unrooted until december because my charge port stopped working after like 3 months...? So I went looking for info and I was brought here, haven't looked back since.

When to check for proper apn info?

Ususally associated with radio upgrades; but rather than get too particular, its good practice to check the apn info after any ROM upgrade. If you think about it, any of the hercules upgrades are going to be the same across the board for any given update. Where they're different is where we want to pay particular attention. In this case, carrier specific information.

Pissed Off Desire HD

Hi everybody, I was thinking whether to open new "story" or not and I thought I can do it by myself..but..I did everything I could, I have read hundreds of forums..some things totally confused me and some simply I don't understand..so however I decided to open new thread because I really need professional help here.
Here is the story,
I've bought used HTC DHD before two days with an custom rom android 4.2.2 but WI-FI not worked and also camera not worked very well (when I take a shot phone turns off). i have tried few roms in hope that will fix the problem (PACman v23, CM10.1 and JT 4.2.2 - and still on JT) but nothing. In bootloader says Unlocked but security is damn ON. So, I worked two whole fckin day without success. I have tried many tools, guides etc but it simply won't make S-OFF. Also I've tried to flash to few stock RUU roms to do a downgrade but every time when try I'm getting some errors (140, 150, 170 or even unknown error xD). I really don't know what to do anymore and because I'm pissed off I came here. I love this phone and I won't sell it third day already. I gave last money for this smartphone..I won't money back..I won't new phone..I just want this to be working device. On pic you can see what I already tried..
So please, be patient and take your time to solve this **** together.

Come on guys, I know this can be fixed. I need just little of your time. and thank you very much in advance.

NO idea why you so desperately want S-OFF in the first place as you can flash custom ROMS without it and there is no other way you can fix wifi on software level (so most probably it's a hardware problem), but anyone have access to search in the upper right corner if you wish.
As for the phone shutting down when taking photos, it's a common problem and is thought to be related to aging battery, but you have a great chance of fixing(compensating) it by increasing CPU voltage a couple of notches. Install CPU Master and increase the mV of corresponding maximum frequency used, it should be 1Ghz to look at if not overclocked, try to increse it by 50mV

You are unlocked and still s-on so, as with every one who has issues like yours, you need to flash the boot.IMG via fastboot from the ROM you want to install, after you've installed the rom.
I suggest switching to SVHD by mygamers, every thing works, its super smooth and is great on battery too.
P.s. unless you REALLY really need the advanced functions of s-off, I wouldn't worry to much about it.
"Some" advantages to unlocked bootloader and s-off are:
Flash new Roms direct with out having to flash boot.img
Restore nandroids that are different from current installed rom easier
Flash radios
Change splash screen (you may only see it when you turn on phone, but it can be awesome thing to show off a bit)

First, why do you need S-Off? You can flash ROMs without S-Off, and S-Off won't fix your WiFi problems. It's not clear whether you're successfully flashing ROMs right now, but you can. You do need to flash the ROM zip's boot.img from fastboot each time after you flash s ROM from recovery.
Second, please bump a thread only once every 24 hours per the forum rules.

It's pretty damn clear that he have tried other ROMS.

But he finishes that line with "but nothing." Given the number of "flash the boot.img" posts I've had to write lately, I was wondering if that meant he managed to get them to boot or not.

Sorry guys that I did't mentioned before but mainly what I want to do is to bring back stock rom but I can't..someone said that I need S-OFF for that, I heard that when you flash stock rom can fix wi-fi and camera and then if you want can install new custom rom after. About damaged hardware, everything is possible. I was in service shop and guy there said that hardware is modem in essence that controling wi-fi, GSM, bluetooth and GPS. Maybe I understood him wrong. But my BL and GSM working just fine. I have to try new step-by-step tutorial, I'll be back soon.

You don't need to get S-Off. Just relock your bootloader with fastboot and run the RUU executable from your computer while the phone's connected to it.

OK, let's clear this. Every rom I've tried worked but wi-fi not again, camera is little stable in JT 4.2.2. Only rom that not worked was JT 4.3 beta 3. Installed very well but when it boots it stays on splash screen forever.

Sent from my GT-I9505 using xda app-developers app

umm if your stuck on splash screen you haven't flashed the kernel. Extract the zip, then place the boot.img into your adb folder. Reboot your phone into hboot then fastboot. Now go to your adb folder type in fastboot flash boot boot.img from cmd.
If that doesn't work to achieve s-off on newer versions of android is 1) Make a goldcard 2) Downgrade with a ruu 3) Get root exploit 4) Get s-off exploit (This was back in 2010 so I don't know if the procedure changed but I s-offed with this. It's probably easier since its 2013:silly
For future reference, Unlocked bootloader means the boot.img is restricted from recovery YOU need to flash kernels via fastboot with Unlocked Bootloader, S-OFF means nothing is restricted apart from splash image, ENG-Soff is engineering mode is same as s-off but with a Eng tag and splash screen is changeable.

First of all there was no any hate nor any of this "agro" of yours lol.
Secondly, none of the mentioned JB ROMS have wifi issues, so there is really no point in wasting time and trying every available ROM.

Stuck on Samsung boot screen

I rooted my old milestone many years ago but havee been keeping my devices stock ever since, until today that is. Today I decided I wanted to try to root my Samsung SGH-I747M with Telus and everything seemed to start off smoothly. Once installed the SuperSU stopped working. I tried fixs I had read online such as updating the app, but this did not work. I read on a forum that you could flash something to disable know to help fix the problem. When I tried going this avenue I was not able to reboot my phone. I tried restoring from a backup taken before flashing, but I havent done any of this in so long im not entirely sure the backup took properly. At one point I got a message saying no OS was installed but after restoring this seemed to go away. I apparently do not remember anything about rooting from my milestone and am hoping someone may be able to help me get out of this mess. I am currently downloading the stock firmware and I think I will try flashing it tomorrow. I also was hoping someone could point me in the direction of a thread on xda that went into a more detailed explanation of how rooting works, what specifically roms and flashing all is and does. Any help is greatly appreciated.

I will be trying to flash the stock firmware tonight but I want to have a clear understanding on what flashing is and what the difference is between os firmware kernel and rom and such BEFORE flashing this firmware tonight. I hope someone will be able to help.

Well that info is already in the Sticky Index. Understanding what you're doing (or about to do) is really important but you gotta start reading, it's all there.
OS, firmware and ROM are the same thing.
When your phone boots, it basically goes: Bootloaders -> Kernel -> ROM (OS).
The kernel has pretty much all the "underground" controls (RAM, Mhz, governor, scheduler, BT, Wifi, etc).
I won't write everything but those are the basics.
Also, having a Canadian variant of the S3 (that's what the M is for), doesn't change much other than flashing bootloaders and stock ROM (which you'll wanna use the Canadian variant bootloaders and Telus ROM for stock). Everything else is basically the same.

Sweet I will definitely check that out. So I did flash twrp to my phone. Is it possible that I flashed the version say for the i747 but not the m version and that is why the phone wont move past the samsung screen? Also should I attempt to get rid of twrp before flashing the stock firmware. This should answer all my questions and then I will explore the stickies some more.

If flashing a stock ROM, flash the Telus one. If flashing a custom ROM, it doesn't matter (I747 or M variant), as long as it's D2LTE.
Your recovery doesn't change anything to flashing with Odin, it will overwrite it.

Flashing the stock firmware fixed my problems. Thanks for all of your help and I will definitely be checking out the links that you sent me before trying to root again tomorrow.
