Losing HSDPA after reboot - G2 and Desire Z Q&A, Help & Troubleshooting

I'm not sure when this began happening as I'm normally on WiFi and don't pay attention to the network speeds, but now that I've noticed it I can't stop trying to fix it.
-I flash a radio.
-Reboot.
-Everything is great. I get HSDPA when expected.
-Reboot normally again.
-Everything is bad. No HSDPA ever. Anywhere. UMTS and EDGE only.
I need to flash the radio again to get HSDPA back. And if I then reboot again, I lose it.
I've tried this with 6 different radio/ROM combinations and it's the same result every time. Even when I wipe and flash a new ROM, I don't get HSDPA. I have to flash a radio to get HSDPA and then if I reboot normally again, I lose it.
Any suggestions? Thanks.

Even on your stock rom? If so might want to check warranty and revert everything to stock

Thanks for the reply. I didn't try the stock Rom. What I did try was flashing the same radio twice and that seems to work...for the time being at least.

Device Reboot when using WiFi or Mobile Interent

Please help. I just got used HTC Incredible.
It is S-OFF, Hboot-0.92, Radion 2.15.00.07.28 and Android 2.2
It is only work when no WiFI and not Mobile Internet.
If I turn on Mobile Interent I have up to minutes to use Interent and then device going in rebootin and white screen. Removing battery sometimes help and device starts loading but then will rebooting again.
Will changing ROM helps?
As I saw a lot of people has similar problems in USA.... may be I got bad device(
You received your DInc with S-OFF? Sounds like someone sent it in and the refurb department didn't do its job in checking the phone and reloading it... then sent it to you.
You could always flash the stock ROM back onto and see what it does.
http :// dougpiston . com/?page_id=108
is where you can get the Stock ROM from. You will need to place it on you SD card and name it PB31IMG.zip
Boot up into your HBOOT and proceed with the update
Thanks! It was on original Rom when I got it but with S-OFF! and was rebooting when try to use WiFi or Mob. Internet.
Now I'm on cyanogenmod 7 and then same problem.
Do I need play with radio version? Will it may help?
If you go back stock it will unroot you..... if you give me some more info I might be able to help..... like when you flashed cm7 did you do a full wipe and what recovery do you have
Plus did you get it from Verizon or Craigslist or something
Sent from my Incredible using XDA App
Yes, I did full wipe.
Now I'm under CM7 and seems it working now more stable. So I can use interent via WiFI near 10-15 minutes. Under Mobile connection near 5-10minutes. If I do just quick connection on 30-60 second it not rebooting at all.
I got the phone from a person who, I think, take it from ebay. It has verizon sign on it.
When I got it was with original lates ROM.
I'm starting think that it is overheating. May be I can low processor speed?
Updated. Also I've installed prog called 'neocore' which does 3d benchmark testing. I need to run just 2-3 times this test and my device starts rebooting.
I had a similar problem when using custom kernels with HAVS or smartass governors on them. Do you have Set CPU or any other program that controls your processing speed/voltage? If so, try disabling them and see if you still have the problem. Some phones do not react well to under/overclocking.
im not sure what kernel comes with cm7 but some dincs dont like multitouch kernels.... and they will kick you off apps and sometimes reboot so i would try switching kernels first.. try one that is close to stock
Just back to stock ROM. And what I see, that if I disable Mobile Internet it works stable. Just turn on Mobile Internet and it starts rebooting. Stock rom has a lot of apps which connect to the internet. Even with disabled auto-update I still see how on booting 3g icons areas and arrows up-down are blinking.
As I see after connection to the mobile internet my device starts rebooting. And only one think helps - remove battery and wait several minutes, which allows boot in successfully. And then if turn off mobile access it will work well (((
Thats odd that ur phone does that. Did u try and change the radio?
Seems that is last what I can try. Or will need to sell it on parts for cheap (.
As I know radio 2.15.00.07.28 is very stable. Which one you recomend to use?
And how to be sure that it will work well with my Current ROM?
Can I install older radio? like 2.07.00.07.16? or even older?
Thanks for help!

i have an idea man maybe you should run an RUU to unroot you and format everything back to the way it was from the factory.... if that dont help it has to be a hardware issue.... let me know and ill help you through it
Thank for helping. Just not sure that unroot may have difference. But will try at last.
What I had found last days. I had changed radio to some version.
On 2.15.00.09.01 was very fast rebooting after try use internet.
On 2.07.00.07.16 was working a bit longer, but not so much.
And 2.05.00.06.11 - the best one! Plus I switched to Stock rom with Android 2.2 and whole day without rebooting.
Only one reboot was when do charging of the device.
The only problem I've under 2.05.00.06.11 that Interent working only via 1x speed. It always tries to connect via 3G, but no luck and switch to 1x.
What do u think now?
Again, thanks for help!

[Q] Losing 3g on Gingervillain 1.3 - 1.9

I've been using GV for months now, but I still have the same issue no matter what kernel I use. If I switch on WiFi, I can't acces my 3G network later on. I have to go to 2G and turn on 3G again to get the connection going again. Putting the device in flight mode also works, but it's a bit of a pain in the ...
I've seen other posts about this problem, but there is no fix that I know of. Any help?
Currently running GV 1.9
Radio: 5.11.05.27
Kernel: 2.6.38.2-defrost-brav
It would be down to the rom and I don't think there is any dev for it anymore... either put up with it or just change rom. You could try updating your radio to 5.14.05.17.
Ok thanks,
I thought flashing a radio was pretty dangerous. How does it work? Same as any other flash?
Yeh, just bung the zip onto your SD, boot into recovery and flash it. Reboot and it will install and your done. It is safer than flashing it through fastboot and it's the way I do it.
Do you have a link to that file?
Nevermind, I flashed a file I found. All is well again.

No 3G or 4G - 1x only - No Nandroid Backup HELP!

So my friend rooted his Evo with Unrevoked. I verified s-off.
He copied a PC36IMG onto his SD which turns out was some 2.1 rooted stock ROM. After doing that his phone could not make/receive calls/text or connect to 1x/3G/4G. Basically an expensive phone that has no phone functions. Everything else works (WiFi included). He flashed http://link.geekfor.me/rootedromzip onto his phone from http://forum.androidcentral.com/htc...vo-install-clockwork-recovery.html#post165998.
When I looked at it, he still did not have a custom recovery so I flashed Amon RA PC36IMG. Full factory wiped data/cache/dvalik. Flashed Synergy RC1. Phone still could not make/receive calls and was getting Error 16 when trying to call. Called Sprint and they reprovisioned phone and fixed calls and texting. Noticed his phone is stuck on 1x and cannot connect to 3G when my phone next to his works fine. Did not test 4G yet since I have poor 4G coverage in my area. Cannot update his profile - just sits there like something is happening but it never completes.
What are his options here? Is it a bad radio or something that we can fix? Can we flash a stock rooted ROM and regain 3G? Remember, no nandroid was made unfortunately.
I would try flashing the latest radios just to be sure. And tell your friend to always make a nandroid backup to avoid this problem in the future.
Well his first time flashing. I think he mistakenly thought the PC36IMG as a custom recovery but it was actually an entire ROM.
Didn't have a chance to nandroid. I'm instructing him how to update newest radio combo and seeing what happens.
Update: Flashed latest combo radio. Updated profile and PRL. Still stuck on 1x even after reboot. Is he hosed? Does Sprint have to do something on their end to fix his EVDO? 4G isn't working either by the way.
Update 2: Wimax Keys Checker - https://market.android.com/details?id=com.joeykrim.wimaxkeys says that RSA Key is present. Relieved that he didn't lose his RSA key. Just can't figure for the life of me why he can't connect to 3G or 4G. Not sure where to go from here? Maybe trying to flashing latest stock rooted RUU? http://forum.xda-developers.com/showthread.php?t=1110733
Bumping for some attention.
Hey, happened to me a couple of times, it will come back. Maybe wipe everything again, have you tried ##data# and entering msl key, wait... Have you updated his data profile in settings

Hello.....did that work for ya?
Sent from my PC36100 using XDA Premium App
Ok, was on the road when I had wife reply...lol.. When you rebooted the phone,did you wipe cache,and dalvik. Then try updating profile? It sounds weird,but has worked for me,without even updating profile. I have had no coverage before after flashing a Rom,also,did just that,and it came back. If rsa keys are present,that is good. If you would be kind enough to reply,whether fixed or not,would appreciate it,anyway,gonna move on...

Did he try updating his profile & prl
Sent from my criffvo
Updating profile and PRL doesn't work. It keeps attempting to update but it is never successful.
I haven't had a chance to get his phone to just try reflashing a new ROM or stock ROM to see what will happen though.
He says using ##data# and entering his MSL code and changing EVDO to automatic doesn't work either.

I would start over again ... wipe completely with Calkulin's "fomat all" zip and flash a rooted stock rom like xhausx. Once the phone boots up, call Sprint and have them walk you through provisioning everything. Once all is well, then move into whatever custom stuff he wants.

You took the words from my mouth!
Is he Flashing the RUU's or just running them through the computer? Normally, you sync your phone or through hBoot and then start the program, try flashing stock Froyo and then factory reset once flashed, it helps clear out traces of old roms etc. If you need anymore help feel free to ask, I would be more than happy!
I don't think it worked.
Calkulin's Format, flashed Odexed http://forum.xda-developers.com/showthread.php?t=1133379.
It showed 3G but I think it was misleading. Wiped and flashed to evodeck and it went back to showing 1x. My phone has 3G showing on evodeck next to his so he definitely has 3G coverage.
I guess it's just time to call Sprint for a re-provision? Does it have to be on a Sense ROM for them to reprovision?

you dont need Sprint to provision, just get your MSL code and do it your self plus I would do a search for people who may of had similar issues and see what they did. Now if that does not work then why dont you check what your network settings are.. See if its set to CDMA(Auto) I remember my Touch Pro I could of set it to 1x maybe something is getting stuck. I think its in ##3282 you check it and I also remember an app on the market called network that did it for you as well.
If that does not work then flash 3.70 radios and then a 3.70RUU and start from scratch.
He already tried ##data#. He can change his EVDO to automatic but it doesn't stay that way.
Alright I don't know how I fixed it but it's fixed.
Just cannot get 4G now. Wimax keys are present. It keeps scanning and cannot get connect. Previously could get 4G at these locations.
I am running EVO as donor/target phone, my is only 1x speed, no matter which rom I try
Synergery, Mik, Stock-Rooted, differ kernal, different PRL, check the data profile Automatic, Try restore but can not cat automatically update, still need to go qpst to update my profile. I have been working on this for two weeks. I went back to my orig phone, it show ev most of time, the speed is must faster than my evo. Searc all over from goole, still no luck, Anyone any idea to try

i know this post is somewhat old. but Making a back up wont take hardly and extra time! always always make one unless you have 100% reliable roms already backed up.

Go back to an old Radio using fastboot?

I recently tried the radio xxkk6 but don't think it's much good for me. My phone always connects to 2g when turned on and takes a while to then find 3g. I have a full 3g signal in my area and have tried changing various settings. This was never the case with xxkk1 so i would like to go back to using that.
I have the xxkk1 image on my laptop ready and waiting. Is it just a case of re entering fastboot and using the
$ fastboot-windows flash radio <image name here>
or do i have to do something else like delete the radio partition first?
Thanks.
Rik.
flash it the same way

Ok i'll give it a go. Is there any way to find out what radio version is installed(obviously to verify it has reverted back)?
go into settings/about phone and check baseband version.

All sorted now. I tried this earlier and my phone was still struggling to get a 3g signal so I'm now left wondering if it was a coincidence. I've just rebooted and it got 3g straight away.
I'm new to all this fastboot and rooting etc and only just started last night.
Thanks.

[Q] Sprint Note 2 LTE Issue

Hello there, I have been in the search for a perfect 4.4 ROM to work, I seem to be at an impass..
The 2 that I have tried, and Quite enjoyed so far are the Omni ROM and the Cyanogenmod 11
Both roms have the same issue, I cannot connect to a 4g LTE Sprint tower. I know the LTE Towers are working, My mom has the same phone, Sprint Note 2 and I have Mac's Rom on it and is picking up a very strong 4g Signal, yet my phone which sits literly right next to it, Refuses to get any 4g.. I drove around, went to known working areas, Never once did I snatch a 4g signal.
I played with the settings, it is set to LTE mode, I even tried Flashing as a fresh Install..
I tried flashing a Stock rom, but for some reason after it installs, and on boot up the phone does not work. I get a blank screen and literly nothing. I have to pull the battery to get it to turn back on. At that point I have to either Re-flash or restore a backup through CWM.
Any help would be appreciated, I miss my LTE Thanks
Same issue here. Not sprint though...
In cm11 set your mobile network type to cdma+lte/evdo or global. See if that works.
Next you can try to flash a touch wiz rom and do a hands free activation, verify lte works on the touch wiz rom, then flash to CM11 and see if you can connect to lte.

I have tried setting it to both. Global shows no signel what so ever on anything, I currently have it on cdma=lte/evdo and I just get a good 3g signal..
I might try that one out, Which is a good touch wiz rom to try and do that with ? I dont think I even tried a touch wiz rom yet

Personally I would recommend doing this:
Backup everything to your PC (both internal and external)
Delete the contents of the "0" folder on your internal card. If you use ES File Explorer, you'll need to enable root access, and then while in the app hit the menu button. The left menu will slide open and you'll see "Local".... underneath that you'll find the "0" folder. The problem is the way CM and Touchwiz mount the file system - they don't do it the same way. So when you do a factory reset in CWM, it doesn't clear out one of those folders. (I found this thread helpful - especially posts 2 & 4) I had major data problems on CM10 for 2-3 months, then I found this out.
After you do that go back to stock. Make sure you download the keep root file as well.
To play it safe, once stock, I highly recommend entering ##72786# in your dialer. The phone will grab the latest prl and update your profile. Whether or not you want to update the software (incl modem) is up to you, but I'd rather not get into the knox world.
Verify working gps. (I prefer "GPS Status")
Then go back to CM11.
I will try that out thanks

Update us on your progress.
If it works, consider hitting the thanks button - at the very least the guy in that other thread - I know I thanked him - his info saved me from going crazy!!!
I had working data (3g/LTE) on any touchwiz, but not on CM. It turned out that I had some corrupted data that wasn't getting deleted upon a factory reset. After I cleared out that data, everything was fine.
Hope your phone is back to normal!
Finally was able to download everything and run the tip, Thanks a lot dude! That helped and that did it ! I got 4g Back and everything is all peachy!!! Thanks again!
