constantly lost signal after flashing to yakju on Tmobile

i just flashed my nexus from yakjuxw to yakju last night, was on Android 4.0.2, baseband was XXKK6, if i remember correctly, i regreted didnt write it down. right after i flashed it, i noticed i lost signal in the living room, but i didnt pay too much attentions to it. today, i noticed when i step out the house on my regular route, i get intermittent lost signal problem, "no service", i had to reboot the phone, then signal will come back, but lose it again in about 2 mins, then might come back later, etc. in on Tmobile at Los Angeles area, baseband XXLA2.
is it possible that i can put the old radio XXKK6 back to this yakju, 4.0.4? how do i change it? can it be done with GNex tool kit or it have to be using CWM?

This is a known issue
code.google.com/p/android/issues/detail?id=28133

I'm on AOKP build 29.
I don't lose signal completely but I often lose HSPA/data connection.
I've noticed this a lot when I use wifi for a long time then switch it off... Rebooting resolves the issue.
Bar shows full signal but no "H" sign and no data. I've waited for a long time afterwards but still doesn't connect.

in fastboot mode, my lock state indicated UNLOCKED, but it doesnt seems that i have root access. superuser indicated" Failed to find currently installed su binary. Update cannot cotinue". Rom Manager said my phone is not root, "Superuser was not found at "/system/bin/su" or "/system/xbin/su". GNex toolkit v5.6 said support root on 4.0.4, what did i miss?
is it possilbe to just flash it back to yakjuxw 4.0.2 thru GNex toolkit?

Uh, I'm no expert, but last time I checked, the lock state shown in fastboot indicates the state of your bootloader, not whether or not you have root. You can have your bootloader unlocked but no root.

You need to fastboot clockwork mod recovery then reboot into recovery and flash su.zip look for the sticky under development that shows how to install custom recoveries.

Did you root the phone again after you flashed the stock img. You can flash any radio I use North America radio UGLC1

i think i know what my problem are, i only have the bootloader unlock, but no root. dont have CWM in it, i will try to root the phone later with GNex tool kit, then flash the CWM with ROm Manager so i could test out that UG radio.
thanks for all the replies!!!

Can't you just put the phone into fastboot, then use the manual method to flash the other radio to replace the last installed?
Or am I missing something?

What.the.heck.
I'm on Tmobile

If you want cwm touch use rom manager to flash standard cwm so the app will know you have it installed then use the toolkit to flash cwm touch.

after flashing to the UGLC1 radio, i c my singals becomes alot more stable than XXLA2, i dont lose signal ramdomly, even im playing with the phone and the phone is not in standby/lock state.
the only problem i noticed is once the phone is locked/standby, if i press the power button, before unlocking the screen, i noticed the signal bar indicated no signals, once in the phone, the bar will come back withing a 10-20 seconds, i know this problem already been reported.
so i tested the phone like leave it untouched, aside for about 15 mins, theoretically the signals should been gone, i should have no services, but when i call from other phone to myself, it always went thru, phone rang. it seens the signal bar just indicated 3G/4G only, but GSM still working in the back even it said no signals.

For me, I wake up the phone and no data. Nothing restores it except reboot. Calling functionally is not affected, just data.
Happened once on stock kernel + uglc1 and once on leankernel + xxla2 + 700mhz-1200.

XXKK6 is the best radio for all 4.0.3 & under roms.

I always lost data connection when I was on xxkk6, then I upgraded my radio to xxla2 n have had steady signal since then......
I use TMobile in Houston....n am using aokp ROM b29 with Franco kernel milestone 2

upgrading from Yakju to Jelly bean... how?

hey all, I noticed that jelly bean is out, sort of.
i would like to put it on my nexus but am sofar unable to make sense of the development forums pertaining to this so hopefully someone here can help me understand this.
I used the efrant's post:

to take my yakjuux nexus to yakju (4.0.4) using fastboot and the stock image provided from google...
I would like to upgrade further, though from what i can figure out JB is only available on takju (yakju with google wallet (works in US only)).

If you're running stock yakju you don't really need to switch to takju. Just install CWM (The Galaxy Nexus Toolkit is an awesome tool to help you do that) and flash this.

You can go from any rom (custom or stock) to jb as far as you have cwm and xxla2 radios..

got some troubleshooting to do... phone wont show up in fastboot... cant use the toolkit until i figure this out.
edit: reinstalled the naked universal driver... shows up in fastboot now.

Does this method wipe everything?

i think it worked, used option 6 for my build of android, then selectedthe option to install cwm touch, followed the instructions in section 3 on:
http://forum.xda-developers.com/showthread.php?t=1614827
Hopefully this will fix the issue i was having with my nexus where the radio would lose all connection to the network... usually have to reboot the phone to get it to work again... a minor annoyance for an awesome phone. Atleast it doesn't take 3-5 min to boot up like my blackberry playbook tablet (that's not cool RIM, please fix)...

it didn't on my nexus... though i didn't use the 7th option which does steps 3-6 (unlock bootloader, root phone, flash recovery) which would wipe the phone.
I just hope i can still send messages on it, last time i flashed it i had to get telus to resend the info to the phone.

another question, I don't think I got the full JB os, as my phone is still using the xxla2 radio... if i wanted to go back to yakju for the full stock OTA update, supposedly coming next month sometime, and keep my warranty, I would just reflash everything back to yakju, including recovery (CWM - stock)?
I assume I would have to do this with the fastboot in the DOS window since I don't think that I can revert everything back to 4.0.4 with the toolkit.
also how do I tell if the phone is rooted? I don't think i did this but would like to know anyways.

Yes, for stock, use adb+fastboot and Nexus Factory Images for everything stock 100%. And to check for superuser, just download an app that requires it and see if you get a command prompt. But even easier than that, SuperUser or SuperSU should be in your app drawer if you have it installed, and also in your /system/app

I don't have those apps installed, guess I am not rooted. Good to know.
Also it should be noted that I no longer have any input lag using poweramp, with ICS 4.0.4 there was always a 1 second (seemed like it anyways) delay between the button press and the phone doing what I want. I hope this extends to using my bluetooth headset as well.

hmmm figured i would try downgrading to takju using the toolkit... it did everything which is nice however i noticed that it still uses the radio from yakju...
is there a way to check what it didn't add to the phone when it downgraded?
edit: I should add that it wiped my phone when I loaded takju...
looking forward to getting the official JB update next month...

I already had bootloader unlocked, so I just had to install CWM recovery and flash the jb-takju image mentioned earlier. Once the phone has rebooted the CWM was gone, so had to reflash that. Afterwards I downloaded the XLFF1 radios (you can search for radio-i9250-xxlf1.zip) and flashed them as well. Now my phone shows all the same versions as the takju phones passed out at Google I/O. All my settings, etc. were preserved.

i really would like to remain stock but get JB as well, what would I need besides that radio to make the takju image from the google site to be prompted to dl the OTA JB update if it is still available to download from google...?

if not, is it possible to reflash with the newer zip without setting everything up again?

good to know, i compared the url's for both links, the one in efrant's post is missing the ) at the end. I ended up wiping the cache's (except for the one that sounds like some guys name) and flashed the zip from it. working great so far.
at the moment I am reinstalling my apps, and i do not think that all of the apps that were in the google folder last time i reinstalled the os, are there. anyone know what the default apps that are supposed to come with the OS are in that folder? I can only remember Layer which I installed manually...

Sorry, I didn't have to reinstall anything, so the apps in my Google folder are the same as before the update. I do however have Currents in the main app drawer which I don't remember having before.

Stuck in wrong build??

Several months ago I purchased the nexus 7 2013 wifi version. In my tiredness after a long day I unlocked, rooted then flashed a custom rom (aokp) my build numbers is KVT49L instead of KVT49H. I must have flashed the LTE version in error.
I'm trying to upgrade from 4.4.2 to 4.4.4. Wugfresh toolkit doesn't work, also unfathomables tool won't work either.
I have been rooting, swapping kernels, unlocking bootloaders and flashing custom since the Droid x days.
I assume I need to use ADB? I am having a hard time finding specific instructions on how to complete this minor upgrade to 4.4.4. In afraid to try anything being on the build for a different version of my device.
any suggestions are appreciated.
I apologize in advance if I left out any critical info regarding my situation.
Edit:
Also are the tool kits not working because I'm on the incorrect build?

K... so, does anyone have any thoughts about just flashing KVT49H rom over what I have?

Why isn't the toolkit working with flash stock and unroot? You should be able to select the option that says it is in a boot loop... And for current version, you can select anything you want - that is what it will flash when you do the flash stock and unroot.
If that doesn't work, where specifically does it fail?
Mike

It goes into bootloader mode and does not come out. Toolkits worked fine on N7 v1. I am attempting to un root and revert to stock.

Toolkit works on v2 as well. When you do the flash stock and unroot, you have to select the option that says your phone is soft bricked.
If that doesn't work, when you are in the bootloader, are you at least able to use the volume buttons and power to select recovery?

Thanks Mike, I'm going to try that

Soft brick option did the trick!! I was also able to restore to KOT49H. Thanks my friend

Possible Brick HTC M8

Hello All,
I think I may have possibly bricked my m8.
I was using cyanogen 11, when I decided to try and flash the GPE rom that is available.
However I did not flash the latest firmware. I am not able to get into fast boot. When I press Power + Volume Down, it takes me too bootloader but no options are available other then press power to reboot.
When it reboots I do get into the rom however, wifi, and service are unavailable for obvious reasons. My Stupidity may have costed me this phone :/ I wasn't able to get s-off with my t mobile variant. It is unlocked, and had TWRP installed.
Any help would be greatly appreciated!

Bricked? But you can get into ROM? Do you even know what a "brick" means?
Just restore your device to Stock and do an OTA to get latest firmware in order to have a working custom ROM on latest firmware. You are T-Mobile, US? Do an RUU, or head over to the Collection thread in General section and download a nandroid backup for your device and restore it from within TWRP(Instructions is also available in the first 2 posts of the Collection Thread).
If you can get it into bootloader/fastboot it ain't "bricked", it's recoverable.

Okay maybe not bricked but I messed it up quite badly, Im not able to get it into the recovery or have it be detected via fastboot. I did try and do a ruu to have it be put back to stock but Im not sure how to go about doing that since ruu cannot see it since it isnt in fastboot... :/

Did you Make sure you update you SDK. Only the latest fastboot and adb will work with lollipop

I did get the latest one from the official site, I was able to use it perfectly fine last night. Now however when I try adb shows the device offline, even if I kill and start the server, and disable and renable the debugging, try different ports etc. I can get it to show the device name, but it says offline next to it, I get no prompt on the device. I was reading the gpe doesnt use fastboot, ( I may be wrong) But that would explain why I dont see anything at the bootloader screen, other then press power to reboot the device.

Good news everyone! I was able to fix it in the most impractical way ever.
So why nothing else worked, I did still have access to the rom which of course had no wifi or service. So what I did was install the terminal emulator via browsers onto my phone, from there I was able to type reboot recovery and restore my backup that I had! and wala, whatya know, now it works, and I dont have a useless phone anymore

Can I go from 4.0.4 to 4.1.1 or higher right away?

Hi all, new comer to the S3 here but not new to flashing etc. I just wanted to get a few things straight before I went ahead.
1. I downloaded and used Mskip unified android toolkit. I rooted and flashed twrp recovery to my S3.
I am on I747UCALG1 4.0.4 and I just wanted to know if I can flash the 4.1.1 build ATT-I747UCDLK3 that I found here straight away in odin. I know some sammy phones are drama queens when it comes to new bootloaders etc. Will the new build update the bootloader or should I do this separately.
Or should I just download a rom from the development section and flash it in twrp or won't that work and I need to flash a new bootloader first then flash the newer roms.
Thanks for any help and yes I did search around but only found questions regarding downgrading.

Bro, remember my strong advice - don't go higher.
Battery life goes worse with every update. I wish I never did it.
But if you want to try something new, try OctOs

The problem I'm having right now is that my wifi keeps on scanning but does not find any networks although I am 2 feel from my router. This phone really was my Gfs that went crazy and I changed out the mainboard so I'm just running it as a back up.

Personally, I would flash stock 4.1.1 from sammobile.com and sim unlock the phone using the free method if the phone is sim locked. Once sim unlocked, I suggest running OTA updates until the phone is running the latest stock ROM. Once it is running the latest stock ROM, flash twrp, take a nandroid backup, and then flash a custom ROM if you want.
Note: once the phone is running the latest bootloader, you cannot downgrade the bootloader.

Would be hard to do an OTA since I cannot connect to any wifi networks.

if youre talking upgrading bootloader/modems , and cannont do as @audit13 suggests , and cannot connect to wifi or use/have enough data ; then i would suggest upgrading incrementally.

No it is on and scans for networks but it does not show any, even if I add a network manually it does not connect. I read somewhere that I need a newer bootloader in order for the wifi to work. Does anyone have the newest bootloader for me to flash and try this out on?

Do the last 4 characters of the modem match the last four characters of the bootloader?
For wifi to work properly, it is best to match the bootloader to the modem and vice versa.
