G1 with NO SERVICE (old radio)

I bought a G1 from someone off of ebay and he said it doesnt recieve signal. I figured I could buy and maybe fix it. The radio is not updated but they wiped the phone before I got it, so now im stuck at the google account sign in with no service. Does anyone have any ideas or do I just need to call up HTC and send the phone in for repairs?
thanks and God bless

try to go through the process of rooting the phone... That may fix some of the issues

but how can I root the phone if i cant get pass the Google account screen? Ive done the bootloader already...nothing happened....i flashed to crb43...that worked but it still didnt solve anything....ive tried to update the radio to the newest but it says "no signature (5 files)"...verification failed. Is there anything that I can do?

what do you mean can't get passed the account screen?
like you try to sign in and you can't?

If you still can't sign in, try using a different ROM like TheDude's and try bypassing the sign in. Maybe you can get it to the main screen and try running some debugging tools and such.

yea cause i dont have any service cause the phone doesnt get any signal....like thats how i bought it..something is wrong with the radio (i guess)...like i just want to use a different ROM that you can skip the account process on so i can ROOT then try to upgrade the radio to see if it will work....but dont you have to have ROOT in order to flash stuff?

well if you are trying to create an account from your phone with no signal, just to sign up on a computer.
the screen does give you an option to skip the sign in process.
what build are you on?
go HERE to get help on bypassing the activation.

Only for ADP1
op: Look in the dev forum helpful threads sticky for a link to activating w/o google account. Also, as a previous poster said, you might want to just do the whole rooting process. Downgrading to RC29 will revert both the radio and android build.

The official OTA CRB43 includes the new radio. If that's what you flashed and it didn't help, flashing the radio isn't going to cure your issue.

Haykuro's IonR2 also gives you the option to skip sign in.

hmmm so i guess i just need to call up htc CC and make up some bogus story saying that cupcake fried my radio....cause i cant even get signal...
i actually had 2 bars last night... so i was able to sign inn and use wifi...but it just randomly cut off....and i wiped my phone....without thinking
so i guess ill give htc a call

Lost signal now at RC29 w/old radio
But I cannot figure out how to proceed. I have been rooting modding for a year now and suddenly lost my signal while the phone was just sitting on my desk. loaded recovery still didn't work, went back to RC29 stupidly and now cannot get newer ADP build loaded because I cannot login past account screen and my Adb isn't working because my phone is not recognized via USB. Is there a secret to that pre-account login? Thanks for any help I have a $400 paperwight right now.

You should be able to enable wifi and login to google. I just went through this process since I don't have any service on the sim i'm using in the g1
--fg

what was the selllers name o ebay. i did the same exact thing and when i got it i updated everything and nothing worked.. i sent it in to htc cause it was under warranty. i told them the truth and its been repaired just waiting on fed ex to deliver it. they replaced the main board and antenna wire

similar problem
sorted: the issue was sim card being faulty.
i recently got an old UK G1 from my brother.
It keeps saying 'no service'. I have downgraded it to RC7 for purpose of rooting but it still says 'no service'.
I was able to bypass initial registration process using adb.
The phone is connecting well to wifi. It is also able to search 'available networks' but does not connect with tmobile.
I have asked for another sim card (it will take a few days to arrive) thinking that the problem is related to sim card but could i be wrong?
Is this problem related to hardware?
Is it possible that wifi, bluetooth and searching network works well and still the hardware is faulty?
what are your thoughts?

[Q] Blocked from AT&T after international travel

I have read through this forum for hours and in no way savvy with this stuff; I have learnt a lot so thank you but please help me.
I just don't know how to tell what the problem is with my phone therefore i don't know which of the 100s of solutions here to apply.
its a S4 i337 previously used on AT&T LTE network, I traveled overseas and used other country's sim card for a short time after giving it to service provider to program. i believe phone was rooted and settings changed for this to happen, though i did not do them or know what they did.
I returned to U.S. and reinserted AT&T sim, made one call, but phone seems to trigger anti theft or network suspend right after. I have had it unlocked twice by AT&T but first use thereafter seems to reblock me out of their network and i get message that this device is blocked from network use. When I call they say phone shows stolen and i repeat process above only to get reblocked again.
I don't know if it is APN settings, previous rooting or what that is causing this? I found an app called SuperSU on the phone, i clicked on its settings and clicked "full unroot" which made app icon disappear but can't tell if I am really unrooted or not. I have also done factory reset and lost everything already, I just want phone to work back on AT&T network as before.

please help me… i am not sure if i need to reroot, delete binary counter, flash with files???? i have read some about odin files, don't know what is the latest and which sources are safe…just confused all around.

please someone tell me where to start

Take it to a best buy Samsung service counter and have them reflash the firmware or update it to MK2. Wipe everything (including internal and external SD card) Then, call att to unblock it again. If it relocks, then go back to the Samsung service counter, tell them the issue and see if they can restore your efs for you from a backup. If they can, do it and then unblock it.
If after all this it relocks, its not your device. Its att who are at fault. Then all you can do is to yell at them.
EDIT:
Another possibility is that the ppl who unlocked your phone overseas stole your imei number and used it to revive a blocked stolen phone. In that case your imei is in an international stolen imei database and you are probably out of luck.

Interesting. If the IMEI was stolen, what would the phone show? Would they clone the IMEI (so it would show the same IMEI) or would it come up as UNKNOWN or blank or something. Reason I am asking is that I've been try to fix an issue with my father-in-law's phone that completely lost the ability to connect to wifi/data after having his S4 "unlocked" in Vietnam to use a local SIM there. Tried may reflashes with MK2 and custom TW ROM's but none work with wifi anymore (data works ok).

If data and calling works then the imei is fine. Its some other issue..

All is speculation but there is a small posibility that when you gave your phone that person gave you another phone which indeed was stolen. Your best bet is to go to the samsung guys right now or learning how to restock your phone. You tube search videos How To Unroot & Unbrick Samsung Galaxy S4

so its been a few days now with no service. it turns out my phone has somehow been programmed with a different imei that comes up as stolen according to at&t. so the theory of my imei having been stolen is pretty possible. every time i have the phone unblocked from the network, one phone call or message causes it to trigger the stolen phone alert and kick me out the at&t network. i have been to the at&t store with my device and the original packaging that shows my original and correct imei but the one that the phone is registering on screen does not match what is on my actual handset sticker and original packaging. the phone never left my sight the entire trip so i am 100% positive my handset was never switched, if anything it was reprogrammed with the stolen imei and they stole mine which is now working fine out there for some crook
i just can't believe that at&t can't verify my original imei that came with the phone i bought from them and just reprogram my phone and get my service going again. its looking like i will need to find a way to recover my imei myself. although i just got the 4.4.2 update that force placed itself on my zero service phone. hope this post helps to alert others to be careful of this type of thing.

Wow! what country did u visit?
If your s4 had insurance I would report the phone as stolen and give the original Imei to be blacklisted and try to get a new phone.

[Q] i9505 cannot register on network

Ok so here's my problem.
I have an I9505 previously with a GE custom ROM and modem version XXUEML2, everything was working fine so far, the only "strange" thing was whenever I reboot the device the Cell Network will take about 3 minutes to reconnect, and I constantly lost the 4g connection which I attributed to problems within my carrier.
So a couple days ago I re-installed my custom ROM (was having problems with the Kernel) and after it boot back I wait to my Cell Network to connect, which never happen. So I went ahead, format everything, re-install the custom ROM and no luck.
I tried everything, updating the Baseband to XXUEML6. Install the Stock ROM (which was locked, but the store where I get it unlocked it by warranty), install another Stock ROM (right now I have the I9505XXUFNC4_I9505PHNFNC1_PHN ROM) and I still cannot get signal).
Did my modem just died, or the "warranty" guys unlock my device in a wrong method. I don't think is a problem with my IMEI 'cause I still have the same as the dive box says.
Hope someone can guide me before I take it back. Thanks.

Well, when I bought the device, it was intended to be unlocked, but for a strange reason my device (only mine 'cause we bought 2 the same day) came carrier locked (MEO from Portugal) So I sent it back to warranty. After a week I get my device back "unlocked" (Same ROM, IMEI) but I notice that it was rooted, which only makes me think that they take it to a third party which unlocked the cellphone with a method that required root. I didn't care, I had signal and 3G,

There use to be possible using this guide, with the old firmwares as far as i know is not possible anymore unless you still have that firmware
http://forum.xda-developers.com/showthread.php?t=2282683
The other way is by an unlocking code ( you can buy in many places) once is unlock , stays unlock..no matter what you flash
Try something go Settings/connections / More networks/Mobile networks/ network Operator/ choose your carrier and see if it let you register, try others and see what kind of message you get

Already tried to choose my carrier, but sometimes it doesn't even appear, and when it does, connecting to it just throws and error saying "Not Registered On Network".
What I fear is that somehow they unlocked it using the Ariza patch (or other unlock method) which should not be used.
Also after digging some info, that kind of error happens when the device have been IMEI locked, which could be also a possibility given that my SIM works on any other device, but not otherwise. I will have to give a call to support service to discard this theory.

Hi ,
I also feel the same that is the problem , it has not been unlock right.
check with them , let me know what they tell you.

Ok, I have more information, typing on the dial *#0011# to get the Service Mode Menu, it says at the bottom IMEI CERTI: NA. But if y dial *#06# I get my correct IMEI, is something wrong with the EFS folder?

Hi ,
Just cheked mine , it said PASS
For sure something happen when unblocking the phone

Need some help getting back into things, thanks!

Hey all! I have made the switch to a Nexus 6P about a year ago, so I am quite rusty with the S5 and how to do things with it. I recently sold an S5 on swappa, and I am attempting to help that user get it back to stock. I would have done this before selling, but we thought the process would have been more simple.
To quote the user I am assisting at the moment "... I crossed into canada a few days ago, phone worked good with international plan. cross back to US and keep getting weird "not registered on network" messages and have 0 connectivity to my Verizon phone network. Tried new sim card, verizon store says the issue is because it is rooted etc (doubt they know what they are talking about)....But figured i'd do a clean install etc and see what happens. Followed instructions for Odin. From what i read it sounds like I need the OA 8 Lollipop retail tar..phone model number is SM-G900V. Keep getting "NAND Write Start!! FAIL! (Auth)" in Odin. Tried multiple USB cables and other random tips I found online. Any advice? Am I using the wrong stock tar?"
What can I/we do to resolve this issue? I have searched xda, but I am totally lost with the S5 to be honest. Things have changed so much since I used the phone that I have no idea where to start. It was on Alliance ROM before I shipped it. It has the Toshiba eMMC (or whichever doesn't have bootloader unlock).
Again, thanks in advance guys!

Some more info about the phone, I'm the buyer.
Still running Alliance. I do have an IMEI # (some sites say that could be an issue).
Model/Phone name is Samsung Galaxy S5 SM-G900V
Baseband Version is G900VVRU2BOK3
Kernel Version: 3.4.0 [email protected] #1
Tue Nov 17 20:06:51 KST 2015
Build number: AllianceROM_VZW_V10_G900V_XXU1BOH4

Exact message I get is "out of service area" when i make a call. then a "mobile network not available" message will pop up after.

Silly question, but have you tried pulling the battery, and Sim, let it sit for a sec, then power on to see if you have service? Might just need to reset the prl. Never been to Canada with the phone so idk what's going on ha.
Could also check the data settings to make sure it's set to CDMA+LTE instead of global or whatever other options it has. You haven't flashed a new radio file, have you? @miketon907

Pulled battery out and sim. No service fix. If I turn phone on with sim card out, it will say "no sim card". back sim card back in, no net work connection....It is set to CDMA+LTE. No, I have not flashed a radio file.

Ok, just trying to rule things out.
You activated the SIM in the US and used it before going to Canada, right?

Yep. so Sim card A which I got after buying the phone was working good. I went to Canada and used same sim card on international plan, went back to US and suddenly phone loses mobile connection and has no service as soon as I cross US border. went to Verizon for sim card B, sim card B does not work either.

You could try just doing a factory reset on recovery if you haven't already. Instead of starting from stock. Just wipe the data partition. If you wipe the system partition it won't have anything to boot into

oh. Well i'll try that later tonight. Report back around 11pm est. thanks!

Try flashing one of the modems on this page. It should reset the radio to have service again. I'd do it without the sim card in. Boot once, you obviously won't have service since there isn't a sim. Then turn off the device, insert the SIM and reboot.
I am looking into the write fail now just in case you can't even flash a modem file.
Also, you downloaded the samsung drivers, correct?
EDIT: I found an old thread that might help you troubleshoot odin - http://forums.androidcentral.com/sa...hacks/391849-galaxy-s5-odin-failing-root.html
EDIT 2: You might just have to switch to a different tar file. This user states that they used the same stock version as the one they were currently on. I'd give that a shot first. Then check to make sure "block reactivation" in security settings isn't checked. The exact directions that should get you going are from a user on that page, as follows;
"chainfire xda quote op-Follow these instructions to the letter. Do not touch any buttons or checkboxes that are not listed below to touch!
- Download and unzip the CF-Auto-Root-....zip file (see posts below this one)
- If you end up with a recovery.img and cache.img file, you've extracted twice. You need to end up with a .tar.md5 file - don't extract that one
- (USB) Disconnect your phone from your computer
- Start Odin3-vX.X.exe
- Click the PDA button, and select CF-Auto-Root-....tar.md5
- Put your phone in download mode (turn off phone, then hold VolDown+Home+Power to boot - if it asks you to press a button to continue, press the listed button, or run adb reboot download command)
- (USB) Connect the phone to your computer
- Make sure Repartition is NOT checked
- Click the Start button
- Wait for Android to boot
- Done (if it took you more than 30 seconds, you need practise!)
NOTE: Sometimes the device does *not* boot into recovery mode and root your device. Just do the entire procedure again if this happens. If it still will not install root and such, make sure that in Odin "Auto Reboot" is not checked. Then after flashing, pull the battery, and boot with VolUp+Home+Power button to boot into recovery manually. This will start the install process.
New to Samsung? Unfamiliar with Odin? Think all the above is a hassle? Get used to it. It's very simple, and us Samsung folk use Odin (or Mobile ODIN ) for everything! It's so very very convenient once you get used to it. Notice the 30 second comment above? For experienced users, the entire process indeed takes only 30 seconds!" - Dale Borrelli
Final note. Try the tar for the android version you are currently on first, then go up to the version you'd like to be on.
Edit: @miketon907 any luck yet?

yes, thanks a lot. flashing the modem worked. have service now again.

Updated Verizon G950U now no service

I have a stock Verizon G950U (on Selectel prepaid but that shouldn't be an issue) and used the PC software to install the latest update NRD90M.G950USQS2BQL1
Immediately following the reboot I have not have service since. My sim works in other phones, took S8 to Selectel store and they confirmed working Sim and said it was a device issue. I have factory reset and even restored the firmware with the software again. I don't get a ton of service in my rural area but was able to activate an old S3 that I had lying around. The Selectel store is also in a larger city with plenty of service.
The radio is on as it shows bars, scans and shows networks, but absolutely will not register manually or automatically.
My limited knowledge and searching says that I cannot directly downgrade the firmware to an older working version. I've rooted older devices but last I played with it KNOX and the risks of bricking are getting ridiculous unless someone can specifically state otherwise for this device and link me to videos and direct download links.
Thanks in advance, I'm pulling my hair out. Short of rooting or waiting for the next update to hopefully fix it I don't know what to do.

I have factory reset and even restored the firmware with the software again. I don't get a ton of service in my rural area but was able to activate an old S3 that I had lying around. The Selectel store is also in a larger city with plenty of service.
The radio is on as it shows bars, scans and shows networks, but absolutely will not register manually or automatically.
My limited knowledge and searching says that I cannot directly downgrade the firmware to an older working version. I've rooted older devices but last I played with it KNOX and the risks of bricking are getting ridiculous unless someone can specifically state otherwise for this device and link me to videos and direct download links.
Thanks in advance, I'm pulling my hair out. Short of rooting or waiting for the next update to hopefully fix it I don't know what to do.

Ok so its not a corrupt EFS issue. have you gone into netwrok and switch to global or anything....
Does it show your phone number in the info as well That will tell if its reading sim or not

It does show my number from sim after booting up without a sim and then inserting. I don't see any global settings. Again from the update no settings changed, since then I've wiped to factory settings numerous times.
I can't find a fricken stock rom file anywhere for crying out loud, just loads of register spam sites.
I think I'm downloading an Oreo 8.0 rom but can I downgrade later and again where's the dam file?

Don't worry about Knox, it's not possible to trip it on a 950u

Tried flashing to BQK5 with moderate success. Passed with Odin (which csc file should I use?) but on reboot it stalled at 32% when installing. Rebooted and after flash screen updated android and showed BQK5 but all my data and apps were there so i likely screwed something up. Installed sim card and momentarily showed 4g and appeared to register but at reboot did the same crap with no service.
Called Samsung prior to flashing and no surprise that was a colossal waste of time. I'm not paying them $200+ to fix an unrelated issue with the back glass that cracked with a case on and phone has never been dropped. They did say that they're partnered with best buy but that's two hours of driving for me...I'd fix the back glass myself and try to get them to give me a new phone if it came to it.
Verizon software shows an update now so I'll let it download (again...takes all night for some stupid reason) and vainly let it flash to current version.
I think I found the Oreo 'final' update so might try that...looks like it installs off an sd card if I can find an old one.
